ITP symptoms and treatment

ITP is a common hemorrhagic disease, causes complex, it is also more difficult for the capital Medical University School of Chinese Medicine of Beijing Medical subsidiary Gulou Chinese medicine hospitals Hall Primary ITP is a professional specialist in primary ITP treatment and research institutions, many of four treatment invalid ITP patients find here the hope of rehabilitation.

ITP is characterized by a significant reduction of platelet, with skin mucosa Purpura, who may have other serious bleeding sites such as nose bleeding, bleeding gums, women’s menstrual of excessive or serious vomit blood, hemoptysis, blood in the stool, and other symptoms Niaoxue , With intracranial hemorrhage is the cause of the disease died. Henoch-Schonlein purpura is characterized by skin limbs scattered spots or affect general, patients with severe joint pain or abdominal pain, blood in the stool, vomit blood, such as the collapse of serious cases can be developed for Purpura nephritis. ITP is divided into two categories of primary and secondary. Primary ITP is an autoimmune syndrome, is a common hemorrhagic disease. Is characterized by blood circulation in the anti-platelet antibodies, so that excessive platelet destruction caused purpura, and giant cells in the bone marrow of normal or more of the naive. Clinical acute and chronic can be divided into two, both pathogenesis and performance have significantly different.

Acute multi-for under 10 years of age, no gender differences. More in winter and spring disease, before the disease has infected more than history, more respiratory infections, , , most; may also vaccination, infection and the incubation period purpura in more than one to three weeks. Adult acute-rare, often drug-related, than with serious illness. Jizhou onset, fever.

Mainly for skin and mucous membrane bleeding, often more serious, skin was bleeding from the size of stasis, the uneven distribution to more limbs. Mucosa have epistaxis bleeding, bleeding gums, tongue oral mucosa Xuepao. Common digestive, urinary tract bleeding, bleeding under the eye of film, a small number of retinal hemorrhage. Common or intracranial hemorrhage, can cause lower limb paralysis or performance of intracranial hypertension, can be life-threatening.

Chronic more common type of primary ITP of 80 percent, more than 10 to 40 years old, men and women for three to four times. Hidden passage of onset. Patients can have persistent or recurrent bleeding, and some local performance for the bleeding tendency, such as repeated epistaxis or menorrhagia. Stasis points and Yuban can occur in any part of the skin and mucous membrane, but the limbs to more remote. Will have gastrointestinal and urinary tract hemorrhage. Trauma may also appear deep hematoma. Intracranial hemorrhage rare, but in the event of acute attacks occur. Breathing deep in the spleen, even reach.

Primary ITP the etiology and pathogenesis, has not yet been clarified. And that is a more immune-related diseases.

At present western medicine treatment of ITP and allergic purpura is the preferred drug hormones, taken after the platelet generally increased, but the side effects of hormone very great increase in platelets at the same time will add many new diseases, such as concentric Obesity, hypertension, diabetes, , and hormone reduction, the platelet will be reduced, after stopping attacks will be repeated. Splenectomy risk of , patients themselves difficult to accept. Spleen is the body’s immune organ, the splenectomy after the immunocompromised patients, easily lead to serious infections, to patients with physical and brought great suffering, the splenectomy after the relapse rate in 58 percent. Is there a method not only increased platelet, disease control, but also alternative hormone, the body will not produce side effects » National autoimmune disease experts, doctors Beijing Gulou Chinese medicine hospitals in Beijing Museum of primary ITP specialist founder Professor Jin Chu-lan mainly of the Group Based on years of clinical , with great concentration study, the use of early-model of the first principle of immunity The establishment of the integrity of the Chinese concept of immunology. The results stated ITP the pathogenesis.

Professor Jin Chu-lan was born in 1952 in Fujian She Nationality Chinese , graduated from the Jiangxi College of Traditional Chinese Medicine. In the autoimmune disease treatment and research for nearly 30 years, keen to medicine, industry expertise in ground handling. Is the capital of the Gulou Chinese medicine hospitals Medical University (Beijing Medical Museum) experts, and as lupus erythematosus, director of the Institute of Dalian, Weihai bimodal director of the Institute of Chinese Medicine, director of the Chinese Society for Chinese Medicine, Chinese Society for Chinese Medicine Council of AIDS , Vice chairman of the China International Association for autoimmune diseases to professionals, chairman of the Committee, “capital of medicine” Magazine Editors.

Professor Jin Chu-lan, ITP is the pathogenesis of pulp, the onset of incentives (such incentives can come from both inside and outside) the stimulation, Ki-hang of Fu’s “pulp” to respond and produce a The whole concept of the viscera model to meet the changes. This pattern projector in a holistic manner to various body organs viscera. Rapidly, and form a new body, and when this status and further strengthen the “pulp” to stimulate the formation of a vicious circle. This vicious cycle of continued role in the body, so that pathological changes in the body, which showed systemic symptoms, skin Yuban or stasis, epistaxis, gingival bleeding, urine, menorrhagia, blood in the stool, cerebral hemorrhage, but also performance To the symptoms of anemia. This is what we said ITP.

Beware of children playing himself flu

Had common cold a few days later, still no rebate fever, cough and increased Nongtan, should pay attention to the mixed infection with acute bacterial bronchitis or pneumonia. Common cold, mostly due to a cold body, or from respiratory infections caused by viruses, often will not arouse people’s attention. But some seemingly cold and fever patients but can not be taken lightly, especially . For these Bianlelian cold, it is timely to go to the hospital for inspection, so as not to delay treatment.

Pneumonia see family

Winter is the season of high pneumonia, the medical experts therefore suggested that the elderly and the infirm pneumonia vaccine should be vaccinated in advance. However, human pneumonia is a big , classified according to different pathogens, there are about 25 to 30 kinds, the treatment also varies.

■ viral pneumonia

Influenza virus pneumonia: assertive in the elderly, and those with chronic diseases, high fever, exhaustion, irritability, theatrical cough, short breath, difficulty in breathing, ineffective antibiotic therapy, the mortality high. 9 annually, in October can be injected flu vaccine for prevention.

Adenosis toxic pneumonia: a predilection for six months to two-year-old infant, rapid onset, high heat, heat-long lethargy, languish and looking pale, white vomit mucus sputum, respiratory difficulties.

Primary varicella pneumonia: more common in adults and older , light, silent, heavy have high fever, cough, pain, hemoptysis, and dyspnea and tachycardia, etc.. Injectable vaccine to prevent .

Other viral pneumonia: infants and , respiratory syncytial virus, parainfluenza virus, nose viruses, such as gastro-intestinal virus caused by pneumonia.

■ mycoplasma pneumonia

Often pneumonia accounted for 15 per cent of the total to 20 percent, the slow onset, fever, sore throat, severe intractable cough, fatigue, muscle pain or rash.

■ Chlamydia pneumoniae infection

Common because of the pneumonia accounted for the first three or four, the elderly, youth Most of fever and angina, sound mute,

■ bacterial pneumonia

Pneumococcal pneumonia: is the world’s most common bacterial suppurative pneumonia, often accounting for more than half of the total number of pneumonia. Sudden onset, a shivering, fever, pain, body muscle-ache, cough, cough rust colored sputum, and other symptoms, and if breathing difficult or gastrointestinal symptoms. Primary was particularly prevalent in males. Secondary was particularly prevalent in , the elderly and those with chronic diseases. Penicillin preferred treatment, the prevention of immune 23-valent pneumococcal conjugate polysaccharide vaccine to protect up to five years.

Legionella infection: multi incidence in the summer and autumn, and often occur in the elderly and immunocompromised persons and chronic diseases. Processes high fever, chills, body muscle soreness, headaches, watery diarrhoea, nausea, vomiting, pain, dry cough, difficulty in breathing, and other symptoms associated with the nervous system. Treatment can be used erythromycin and rifampin or cyproterone scrapping Star.

Klebsiella pneumonia: often occur in middle-aged men, long-term alcohol in patients with chronic bronchial pulmonary disease, viscous sputum, a red brick, it is difficult Gaichu, some hemoptysis. Available cefazolin and gentamicin treatment.

Staphylococcus aureus pneumonia: multi-secondary, rapid onset, recurrent fever, chills, sweating, pain, dyspnea, cough, cough or Xietan purulent. Penicillin can be used or new cefalotin treatment.

Pneumonic and pulmonary anthrax: two very similar symptoms have chills, high fever, pain, cough, Xue Tan, difficulty in breathing. The former can be found in sputum bacilli; latter livestock and germ warfare agent anthrax exposure history, could be detected in sputum Bacillus anthracis.

■ other

Other pneumonia are anaerobic pneumonia, pulmonary fungal infections, Candida disease, pulmonary infection with AIDS (, Pneumocystis carinii pneumonia).

Understanding viral pneumonia

Viral pneumonia is caused by a variety of infections bronchial pneumonia.
Many viruses can cause bronchitis, a few can cause pneumonia. Infants and is the most common respiratory syncytial virus, adenovirus, parainfluenza virus, influenza A and B viruses. In healthy adults, the only common the viral pathogens is A, influenza B virus. sometimes, adult viral pneumonia can be adenovirus, - zoster virus, Epstein-Barr virus, Coxsackie virus and Hanta virus. elderly are important pathogens the influenza virus, parainfluenza viruses and respiratory syncytial virus. impaired immune cells from patients often latent virus, especially cytomegalovirus (CMV) or herpes simplex viral infection. Furthermore, the majority of infections due to non - the immunity contact with the pathogens caused by the people.

Pathological changes

The virus penetrated thin bronchial epithelial caused bronchiolitis, the infection can be broadcast interstitial and alveolar caused pneumonia. Congestive lesion site, and sometimes bleeding from mononuclear cells in the strong participation of the inflammatory response. Alveolar fibrin content within alone nucleated cells, occasionally, polymorphonuclear leukocytes. serious cases, a transparent membrane. adenoviruses, cytomegalovirus, respiratory syncytial virus, or - zoster virus can see characteristics of the cells with the virus within inclusion bodies.

The main clinical manifestations

Most of the patients have headaches, fever, muscle pain and mucus purulent sputum with the cough.
1. Slow onset, headache, fatigue, fever, cough, cough or a small number of present phlegm, symptoms generally lighter.
2. Immunodeficiency patients, and the illness was more serious, sustained high fever, palpitation, dyspnea, cyanosis, extreme exhaustion, can be associated with , failure and azotemia.
3. signs less, there are limitations of a small amount of breathing and the sound weakened wetlands Romanian Music.

Diagnosis

1. Will occur in winter and spring, the outbreak or epidemic can be distributed. 2. Onset slow, often accompanied with upper respiratory tract infection, persistent dry cough. signs less. 3. Normal blood leukocyte count, lower or slightly higher. 4. Etiology inspection: Virus Isolation: sputum or isolated virus; removed respiratory secretions or biopsy specimens isolated virus; respiratory secretions of inclusion bodies in the nuclei can be suggested that the virus infection. Serological examination: Complement combination test, hemagglutination inhibition test, and test specific IgG antibodies in serum; immunofluorescence assay, ELISA and RIA detection of the virus in serum IgM antibody specificity. Virus detection and viral antigens: Remove respiratory secretions or tissue biopsy specimens, found cells by light microscopy within inclusion bodies; electron microscope using immunofluorescence assay respiratory secretions or exfoliated cells in the tissue of virus antigen. 5. X-ray examination-see spots, patchy or uniform shadow on both sides was particularly prevalent in the next 2 / 3 field. Pleural rarely involved. 6. Antibiotic treatment ineffective.

Therapeutic Use principles

Treatment principles
1. Mainly symptomatic treatment, prevention and treatment of secondary bacterial infection. 2. Antiretroviral treatment. 3. Strengthen support therapy. 4. Treatment complications.
Medication principle
1. General cases mainly to symptomatic treatment, cough expectorant and added all kinds of vitamins and other complementary medicine. Ling virus can be oral or ribavirin. 2. Severe cases mainly by intravenous medication, therapy and support to prevent complications. Treatment under conditions corresponding extension. 3. Merger bacterial infections, according to clinical and sensitivity test to choose effective antibiotics.

Drug Treatment and Evaluation

Drug therapy
To have herpes simplex, or varicella zoster infection of the lungs, generally advocate the use of acyclovir, adult 5 ~ 10 mg / kg every 8 hours 1st, or 250 mg/m2 body surface area every eight hours 1st . in organ transplant recipient, cytomegalovirus pneumonia can be used ganciclovir 5 mg / kg intravenous injection two times a day, and the use of immune globulin (intravenous immunoglobulin or cytomegalovirus immune globulin). this treatment of AIDS patients had no significant effect (prevention and treatment of influenza in section 162 of influenza in the discussion).
Some patients, particularly influenza patients, such as the merger of bacterial infections require antibiotic treatment. Common pneumococcal is the main pathogens and Staphylococcus aureus, followed by the Haemophilus influenzae, A β - hemolytic streptococcus and Neisseria meningitidis cocci. pathogenic microorganisms, patients of different age and complications, prognosis also is greatly different. treatment based on pathogens may be.
Evaluation
1. Cured: symptoms, signs disappear, X-ray showed shadow completely absorbed. 2. Turn for the better: symptoms, signs disappeared, the shadow of the absorption. 3. Surprised me: symptoms, signs or no obvious changes deterioration of pulmonary lesions not absorbed or deterioration.

Preventive measures

Virus antibodies later, the infection control is very limited. Interferon on susceptible cells infected with the virus has a protective effect, prevent disease and prevent its spread development role. Cellular immune control on the role of a virus, such as leukemia or Hodgkin’s disease cellular immune defect, it is easy to feel a and virus, and no other virus susceptibility. The current domestic already widespread inoculation of infants live attenuated vaccine, has now extremely rare, pneumonia even rarer.
Human immunoglobulin passive immunization on the susceptibility of patients, especially against and have a protective effect. Specific vaccination on influenza, adenovirus, such as despite protective effect, but not completely prevent attacks.

Genital herpes diagnosis and differential diagnosis

HSV infection to the diagnosis based on history, clinical performance and laboratory test results may be. A history of dirty sexual intercourse, and parts in a primary blisters and skin erythema, it is not difficult to diagnosis, and so easy to relapse. If necessary, can be used for blister fluid smears, nurturing, Vaccinations, immunofluorescence inspection. Determination of serum immunoglobulin antibody, among other things, help to diagnosis and determine the virus type.

First, cytology method

The films do lesions scraping Wright-Gemsa (Tzanck test) or Papanicolaou stain, HSV detection of cytomegalovirus infection characteristics of packet letter, but HSV infection or - zoster virus infection, the sensitivity was only virus isolation 60 percent.

Second, culture

Bottom from blisters to do tissue culture based separation virus, for the present more sensitive and specific method, takes 5-10 days because of technical conditions and high requirements, which is very expensive, not widely used. Third, antibody detection

Now is the most widely HSV-2 antibody detection, such as the Western blot method could also be used gD2 for antigen detection of HSV-2 antibodies, sensitive, and can distinguish between HSV-1 and HSV-2 advantages.

Fourth, diagnosis

Chancroid soft for the quality of ulcers, although local recurrence pain without the history, laboratory examination chain was positive.

Other sites skin diseases such as herpes zoster contact, Behcet’s disease. Pustule sometimes with herpes similar, from the history and examination of the distinction.

Syphilis laboratory

Previous laboratory tests have Treponema pallidum inspection, syphilis test serum and cerebrospinal fluid examination. With the development of gene diagnosis technology, PCR technology applications of DNA testing Treponema pallidum, the syphilis diagnosis become accurate, rapid and sensitive.

First, Treponema pallidum inspection

(1) inspection methods

1. Dark-field microscopy: skin lesions, using slide organizations exudative fluid or lymph node puncture fluid, see that the activities of Treponema pallidum.

2. Immunofluorescent staining: green fluorescence microscopy showed the Treponema pallidum.

3. Biopsy examination Treponema pallidum, such as silver staining (Warthin - starry) Act, or (Levoaditis Act) or fluorescent antibody staining, available on the see Treponema pallidum, a dark brown, spiral structure, located in the surrounding dermal capillary. Silver stain positive results have to be interpreted cautiously because similar Treponema pallidum of other substances easily confused. While specific fluorescence tests were more reliable. (B) Identification of spirochetes

Endoscopic examination Treponema pallidum and Yaws, endemic syphilis, for his three non-venereal spiral of identification, and the tooth should also be of great spiral, helical gear of the small, soft spiral body, the spiral of phase identification.

1. Yaws, endemic syphilis, for his three non-STD spirochetes: morphology and Treponema pallidum not distinguish, but epidemiology, medical history, clinical manifestations can be identified;

2. Teeth of the spiral: reduced spirochetes than Treponema pallidum longer exists in the oral cavity, particularly the largest in Chifeng;

3. Tooth small spiral of: shorter than Treponema pallidum, Rotary also short distance, irregular movement at both the central slightly more width. Scale were seen mainly in the tooth; 4. Soft spirochetes: dredging of the spiral, spiral less, law and not fast, often changing its shape. The parasitic skin ulcers.

5. spirochetes: short than Treponema pallidum, the spiral of big without rules, born in overcast dirt, not regular cleaning to a higher detection rate.

6. Other: spiral-shaped mesh fiber, fiber protein filaments, cilia, string-cell, and other objects of a spiral differential.

Second, syphilis serum test

According to different antigen used, syphilis serum test is divided into the following two categories:

(A) Non-Treponema pallidum serum antigen test motives for phospholipid antigen in the serum of anticardiolipin antibodies, also known as Su-reaction. This high sensitivity and specificity test lower, it can easily happen biological false positive. Patients with early syphilis fully after treatment, the reaction-can disappear without treatment early to late in the reaction of some patients may also be reduced or disappear. As the current general screening and quantitative tests, observation of relapse and re-infection. 1. Sexually transmitted diseases research laboratory test (Venereal Disease Research Laboratory test, VDRL); intentions phospholipid, lecithin, and cholesterol as antigen, can be used for quantitative and qualitative tests, reagents and control serum has been standardized, low-cost. This method commonly used, simple operation, preparing microscope to read the results, the deficiency is a syphilis sensitivity is not high.

2. Quick-reaction test plasma (Rapid Plasma reagin test, RPR): VDRL antigen improved sensitivity and specificity and VDRL similar advantage is the naked eye can read out the results.

3. No heating of glass test seropositive (Unheated Serum Reagin USR) is also VDRL antigen improved sensitivity and specificity and VDRL similar.

(B) Treponema pallidum serum antigen test: living or dead Treponema pallidum or their components to make spiral of antigen-antibody determination. This test sensitivity and specificity are high, generally used to confirm test. This test is to test anti-serum IgG antibody Treponema pallidum, even after adequate treatment of patients still exist for a long time, even lifelong not disappear, serum continued existence of positive reaction, therefore, can not be used to observe the effects.

1. Fluorescence Treponema pallidum antibody absorption test (FTA-ABS Test): This method is more sensitive and specific than the helical body experiments.

2. Treponema pallidum hemagglutination test (TPHA): sensitivity and specificity are high, easy to operate, but on a syphilis test as FTA-ABS sensitive.

3. Syphilis system dynamic test (Treponema Pallidum immobilization, TPI); spiral of strains with Nichol (live) plus serum (containing antibodies), in meeting with the participation of inhibited spiral of events. If ≥ 50% Treponema pallidum stop their activities, compared to positive. This test specificity and sensitivity are high, but high equipment requirements, operational difficulties, only research.

Third, gene diagnosis technology detection Treponema pallidum

Treponema pallidum not conducted in vitro. Clinical specimens of Treponema pallidum in the most sensitive and reliable test method is infected rabbits (RIT), live RIT can prove the existence of Treponema pallidum, the syphilis testing is commonly used standard methods. But with RIT on neonatal or adult conventional diagnosis of syphilis is not realistic. Syphilis serology diagnosis and treatment of infections identified significant, but not sensitive to the early diagnosis of syphilis, congenital syphilis and the diagnosis of nerve enough specificity. Serological tests for the diagnosis of congenital syphilis, the first problem is to be asymptomatic infected babies from the non-infected babies separately, these baby’s mother serum test positive syphilis, the difficulty lies in not humoral immune response to mothers with babies antibody response phase difference, because the mother’s IgG can be passed to the fetus. Also due to the existence of IgG life, it is difficult to evaluate the treatment results. Serological diagnosis often time, there is the false positive.

PCR Treponema pallidum DNA, highly specific, high sensitivity, is the diagnosis of syphilis in advanced methods.

(1) the design of PCR primers location and sequence:

At present, there are four sets of Treponema pallidum DNA amplification systems: Amplification 47 KDa membrane antigen gene (tpp47 gene), amplified 39 KDa alkaline membrane protein gene (bmp gene), amplified TpF1 protein gene (tpf-1) or TyF1 protein gene (tyf-1) and gene amplification tmpA.

(B) the methods of operation

1. The collection of samples, according to the patient’s condition may take partial discharge, collected lymph node fluid, amniotic fluid, serum and cerebrospinal fluid. Distilled water with proper dilution, stored at 4 ° C refrigerator.

2. Sample handling: purpose is to expose the DNA Treponema pallidum, the elimination of specimens of PCR inhibitors. The following approach.

① boiling method: take 10 or 20 μ l serum or CSF Add 0.5 ml micro centrifuge tube, the water bath in boiling 10 minutes after cooling in the ice bath, 13000 g centrifugation 10 s, the supernatant for PCR analysis.

② low speed centrifugation: 100 μ l amniotic fluid, serum or cerebrospinal fluid into the 900 μ l sterile phosphate buffer, 10000 g centrifugation 10 min at room temperature, the supernatant was transferred to another microcentrifuge tube, 20000 g4 ℃ centrifugal 1 h, The supernatant was removed, suspended sediment 50 μ l sterile water, direct boiled for 10 min, ice bath cooling, supernatants from 40 μ l for PCR.

③ alkaline lysis method: take specimens 100 μ l collection in Canada with 1 mol / L NaCl, 1mol / L and 0.1% SDS NaOH solution in boiling 1.5 min, with 400 μ l (0.5 mol / L), Tris-HCl (pH 8.0) and . With the same volume of phenol extraction, then to 100 μ l 0.15mol / L NaCl phenol extraction. The entire 600 μ l solution with the same volume of chloroform: isoamyl alcohol (24:1) extraction, and then use the same volume of isopropanol precipitation (-20 ° C too fluid). 13000 g4 ℃ centrifugal 15 minutes, Along amylin suspended in 51 μ l sterile water, from 20 μ l as PCR template.

(C) PCR Amplification

1. Amplification 47 KDa membrane antigen gene: 100 ml of reaction of: 10 mmol / L TrisHCl (pH8.3), 50mmol / L KCl, 3mmol / L MgCl2, 100 μ g / ml gelatin, 0.5 μ g primer (47-1 and 47-2) , 75 mmol / LdNTPs, 2.5U TaqDNA polymerase. Preparation of various different from the DNA as template, the reaction process: 94 ° C 15 s, 60 ° C for 1 min, 72 ° C for 1 min, cycle 40, the end of the cycle to increase 72 ° C for 10 min extension of time, from 10 ml of reaction by 1% agarose gel Electrophoretic analysis. Dot blot analysis product: from 10 mlPCR amplified products by adding 10 ml0.5mol/LNaOH-1.5mol/NaCl solution degeneration 10 min, with 380 μ11.5 mol / L NaCl - 1mmol / L Tris (pH 7.2) and then use Minifold I point Films, 80 ° C vacuum processing film for 2 h with 496 bp probe 65 ° C hybridization overnight. Probe for primer 47-3 and 47-4 the PCR product with random primer labeling.

2. Amplification 39 KDa alkaline membrane protein gene: 25 μ1 reaction system including: 1 × RT buffer, 50 mmol / L Tris-HCl (pH 8.5), 50mmol/LNaCl, 4mmol/LMgCl2, 2mmol / L DTT (Kisumu sugar disulfide Alcohol), 200 μ mol / L dNTP, 100 µ mol / L primer (TP7 and TP8), 0.01% bovine serum albumin (no DNase and RNase), 1UTaqDNA polymerase, 5 μ1 sample, which may be included in 0.05 mmol / L 4-chloro enhance methylamine PCR.

PCR1: by using primers TP7 and TP8 amplified a 617 bp fragment, the reaction process: 94 ° C for 3 min and entered the cycle of: 94 ° C for 1 min, 65 ° C for 1 min, 72 ° C for 1 min, cycle number 30 or 35, each cycle of 72 ° C extension increased by 5 s, the last extension of time to 6 minutes.

PCR2: reuse nesting primer TP3 and TP4 amplified a 500 bp fragment, PCR1 product with distilled water diluted by 10 times, from 5 μ1 for the second time amplification. PCR2 of MgCl2 and primer concentrations of 5 mmol / L and 20 μ mol / L primer ( TP3 and TP4), and other conditions and PCR1 same.

PCR products were analyzed. ① from 10 μ1 reaction products by 2% agarose gel electrophoresis; ② Southern blot, using oligonucleotide probes TP5 (32P for end labeling) hybridization.

3. Amplification TpF1 protein gene TyF1 protein gene: 100 μ1 reaction containing: 50 mmol / L KCl, 10 mmol / L Tris-HCl (pH8.4), 2.5mmol / L MgCl2, 0.2mg/ml gelatin, 1 µ mol / L dNTP, 2mmol / L primer (F1 and F2), 2.5UTaqDNA polymerase, 10 μ1 treated rabbits testicular Treponema pallidum suspension, the reaction process: 94 ℃ 1min, 55 ℃ 1.5min, 72 ℃ 2.5min, cycle 40 times, from 10 μ1 PCR products used 2% agarose gel electrophoresis, Southern blotting, with tpf-1-specific probe F3 and tyf-1 special foreign body hybridization probes F4, respectively.

To achieve maximum efficiency amplification reaction parameters should choose the best value. Use the double-stranded DNA probe fragment detection of PCR products, rather than synthetic oligonucleotide probes, as this can be labeled high specific activity of radiation. In addition, the largest fragment probe can reduce wild strains tpp47 variable sequence and false negative results due to the Taq DNA polymerase base substitution errors led to the false negative results. Experiments confirmed: PCR can really achieve the sensitivity of detection tpp47 copy level.

Because clinical samples may contain a large amount of personnel cells and microorganisms, the establishment of Treponema pallidum highly specific PCR method is very important. Despite the large number of As noted in support of 47 Da membrane antigen gene and its corresponding gene with Treponema pallidum specificity, but also in-depth study of the specificity of the method. In EB stained agarose gel occasionally visible non-specific PCR products, (such as amplification gonorrhea Nyquist cocci), on the need for tpp47 specific probe hybridization to increase the specificity and sensitivity. Only Treponema pallidum subspecies of syphilis and Yaws subspecies of chromosomal DNA obtained specific PCR products, show that the pathogenic spirochetes very close relationship and 47 Da immune highly conserved protein antigenicity. Amplification tpp47 not as if the conventional method can distinguish between syphilis and of Borrelia burgdorferi, using serological tests in the diagnosis of Lyme disease and syphilis, there are two spiral cross-reaction.

Treponema pallidum subspecies of syphilis tpf-1 gene in 123 locations A, Yaws subspecies tpf-1 gene in 123 locations for G, Noordhoek with tpf-1 or tpf-1-specific oligonucleotide probe (two probes only one nucleotide different) testing different strains tpf-1 or tpf-1 gene amplification product. The results show that: it can not tpf-1 or tyf-1 gene 123 locations nucleotide difference between syphilis to the different subspecies. These strains isolated from patients with syphilis, some have spent several rabbits passage through the fresh clinical specimens Treponema pallidum DNA analysis and comparison, the above results may be due to Treponema pallidum in the passage by the mid-point mutation.

4, cerebrospinal fluid examination

For the diagnosis of syphilis nerve, including cell count, protein, VDRL test, PCR, colloidal gold test. Neural asymptomatic except for syphilis, all syphilis patients who period of more than one year should be for cerebrospinal fluid examination. Early Congenital Syphilis all babies should also check with the exception of cerebrospinal fluid of the central nervous system involvement may be. Cerebrospinal fluid cell count and the total protein amount of the increase in non-specific changes in neural CSF VDRL test is a more reliable diagnosis of syphilis basis. However, when the activities of the presence of syphilis, CSF white blood cell count often increased (WBC> 5/mm3), it also CSF white blood cell count is often a sensitive indicator of judgment. Conditional CSF PCR units will be fast and accurate diagnosis of syphilis nerve.

5, syphilis false positive serum reaction

Technical false positive: high sensitivity antigen, serum specimens made a mistake or hemolysis or bacterial contamination, the inspection room technology unskilled.

Biology false positive: spiral of non-antigen positive rate higher than the serum test spiral of serum antigen test. The former is to test the response of the patients, which is to test anti-Treponema pallidum antibody. The spiral of non-antigen test used also exist in other organizations, so other diseases have emerged even occasionally normal reaction of, in certain diseases occurred positive reaction against syphilis case called false positive.

1. Acute biological false positive: these diseases in the six months to overcast.

Seen , , , infectious mononucleosis disease, upper respiratory tract infections, , subacute bacterial endocarditis, pneumococcal pneumonia, active , filariasis, typhus, trypanosomiasis disease, relapsing fever, leptospirosis, malaria, but the low titer, in 1:8 following general, when using serum antigen spiral of FTA-ABS or TPHA test, serum negative reaction. PCR negative.

2. Chronic biological false positive, and sustainable for more than 6 months or a few years or even for life, can be divided into two categories:

(1) non-spiral of serum antigen test false positive; these diseases common in autoimmune diseases such as systemic lupus erythematosus, disseminated discoid lupus erythematosus, autoimmune hemolytic anemia, and systemic sclerosis, rheumatoid , rheumatic disease, cirrhosis, nodular more arteritis, Sjogren’s syndrome, chronic glomerulonephritis and heroin addiction, titer up to 1:64 ~ 1:128; minority pregnant women, the normal crowd false positive rate of 1% -2%. In over 70 years old in one percent false positive.

(2) antigen in serum spiral false positive rate than non-spiral of serum antigen test less, although some other disease patients FTA-ABS false positive, the staining was often weak or non-typical “beaded - like.”

(3) serum syphilis false negative reaction

1. A syphilis hard chancre:: General hard chancre: in 2-3 weeks, before a reaction of the body, so early response negative serum.

2. Immediate treatment of syphilis infection or advanced syphilis: Because of low serum response, a negative.

3. Secondary syphilis false negative; less than 1% of the patients with secondary syphilis not diluted its serum VDRL test were negative or weakly positive reaction, but in a highly diluted as positive, that is, before the band phenomenon (Prozone phenomenon), it is serum anticardiolipin antibodies in excess inhibit positive results.

4. Technical operations or antigen in serum low-sensitivity test negative.

Eyelid Vaccinia the diagnosis and treatment

[Diagnosis]
1. History often Vaccinia vaccine vaccinia vaccine or skin splash into history.
2. Obviously redness, and there Vaccinia-like pustules, pustular pierced forming ulcers, skin healing callus appeared, after forming a permanent .
3. A small number of cases, secondary Vaccinia conjunctivitis or keratitis.
[Treatment]
Treatment of herpes zoster and basically the same.

skin disease
According to the common causes of skin disease can be divided into:
Bacterial infection of the skin: ① erysipelas, caused by streptococcus infection subcutaneous tissue inflammation, and more involvement on the lower at the same time, the primary infection rare, facial or more since spread from nearby organizations. fever, quality hard, smooth surface, congestive was bright red lesions edge clear, with a high degree of swelling of the eyelids can not be opened, local pain and tenderness, swelling of submandibular lymph nodes often. ② pus cell disease, also known as septic callus , staphylococcus or streptococcus infection by the cause. Staphylococcus pustular disease for the easy proliferation of superficial suppurative skin infections, for the early cluster of yellow pustules, pustular rupture, the callus formed on the surface of pale yellow skin, Pustular streptococcus infection without disease characterized by the integration of erythema, a surface blisters, Rupture very thin-walled, easy adhesion formation of the yellow scab skin, the skin scab off easily without leaving scars. ③ unusual lupus, the skin for the most common form of . Often onset in childhood or infancy, in the beginning under the translucent skin and soft small nodules, a light red, yellow or brown red, nodules gradually increasing expansion and integration into a brown-red, to the visible glass pressure of brown powder in small point that the so-called “lupus nodules “Edge was irregular activities change, the central part of ulcer formation or . ④ furuncle swollen eyelids, occurred in the vicinity of the eyebrow. General Staphylococcus aureus infection of hair follicles caused inflammation of the mouth, followed far spread along the hair root of the formation of inflammatory sclerosis, congestive swelling of the skin, a few days later, the top of a sore filthy yellow-green pus suppository, swelling pain intensified, preauricular lymphadenopathy, the worse the temperature increased, with some pus toxicity , thrombosis of the cavernous sinus .
Virus infection of the skin diseases: multiple body from the bottom, according to clinical manifestations into vesicular, and the rash of new biotype. Common: ① herpes simplex, caused by the herpes simplex virus, with more body heat in STDs, can possibly complicated by the herpes simplex keratitis. ② herpes zoster, of the ? Herpes zoster virus, characterized by distribution along the trigeminal nerve (mostly first) with inflammation in the skin herpes generally confined to the side. ④ molluscum contagiosum. ⑤ other infections, such as smallpox, chicken pox, and other systemic diseases may occur in the with the same skin damage.
Fungal skin diseases: multiple by the , face or other parts of the body from the spread, in the shallow - and deep-two. The superficial skin organized by various fungal infections of Trichophyton, the ball of spores, such as Candida caused. The Trichophyton for those infected with the most common skin psoriasis ring, the first to use red spots, gradually expanding to the surrounding form surrounded by edge brown yellow spots. Ball blister son of disease secondary to the more systemic infection, at the beginning, was micro-red skin nodules, can rupture the pus from the rich fungus, and ultimately the development of ulcerative Chenghua pyogenic granuloma block. Violations of the conjunctiva and deep organizations such as cryptococcal fungi, Candida albicans, bacteria and spores silk Actinomyces by the face and other parts of the body from expansion.
Allergic skin disease: more concerned with the systemic immune mechanism. The most common have eczema, , contact dermatitis, psoriasis, erythema multiforme and other allergic skin.
