Objective To investigate clinical and MRI features of the reversible posterior encephalopathy syndrome (RPES).Methods Clinical and MRI materials of 4 RPES cases confirmed by integrated clinical diagnosis were retrospectively analyzed.Results All the cases presented with a rise of blood pressure.The neural symptom include severe headache (2 cases),dysphoria (3 cases),blur of vision (2 cases),impairment of impermanent memory (1 case),seizure (2 cases).In MRI,the lesions mainly systematically located in posterior parietal lobe and occipital lobe in all cases,or randomly located in frontal lobe (2 cases).Lesions demonstrated high signal on T_2 weighed and water-suppressed sequences in MRI.The lesions dominantly located in cortex in 2 cases,in both cortex and subcortieal white matter in 1 case and in subcortical white matter in 1 case.Four cases resolved their lesions when re-examined. Conclusions RPES represents such characteristic MRI findings as symmetrical distribution of reversible lesions in posterior brain with involvement of cortex or subcortieal white matter.When combined with hypertension and neural symptoms caused by involvement of posterior brain structure,it is helpful for early differential diagnosis of this syndrome.

Aim To prepare and identify monodonal sntibody (Mab) specific for Toaoplasma gondii tachyzoites. Method The Mab specific for Taxoplasma gondii tachyrzoite were prepared via bybridoma technique. Indirect ELISA was used to determine the activity of the Mab. Agarose double immuodiffusion test was performed to confirm subclass and SDS-PAGE & western blot were used to analysis rolecular weight of the antigen (s) recognized by the Mab. IFA was used to identify the epitope of Taxoplasma gondii tachyzoites. The protection and specificity of the Mab were snalysed at same time. The Mab was tesed in Mab-ELISA method to detect Taxoplasma gondii antigen. Results A Msb F7C8H12 specific for T. gondii was produced. It belongs to IgG1 subclass. Moleculsr weight of the sntigens recognized by the Mab was 16.5 and 24 kDa. IFA did not show fiuorescence in intact tachyzoite.Inhibition test showed that the inhibition rate was 50% when the concetration of the antigen was 40μg/ml.Afterthe RH strain tachyzoites were incubated with Mab ascites, mice were inected with the tachyzoites through peritoneum. The results showed that the mean dead time of mice were not delayed. T. gondii antigen mixed with PBS snd normal human serum was detected by Mab-ELISA, the sensitvity was 0.78 yg/ml and 1.5μg/ml respectively. When mice were infected with T. gondiiRH strain tachyzoites, 103/mouse p.i., circulating antigen could be detectedin 6 day and 8 day. Conchusion The Mab (F7C8H12) to T. gomdii tachyzoites is an excellent probe for studying T. gondii snd toxoplasmosis.

It has been 50 years since the discovery of thyrotropin receptor autoantibody (TRAb). Advances in the knowledge of thyrotropin receptor ( TSHR) structure and function, combined with the elucidation of TSHR signaling and TSHR-autoantibody interaction have greatly facilitated our understanding of TRAb and their clinical applications. Measurement of TRAb activity plays an important role in the diagnosis of Graves' disease ( GD) and Graves' opthalmopathy. It has also been well recognized that TRAb is an effective predictor of GD relapse or remission after antithyroid drug and radioactive iodine treatment. TRAb test is of particular help in pregnant women and lactating mothers with recent iodine load, where radioactive iodine or technetium tests are contraindicated. In addition, it is useful in the diagnosis and differential diagnosis of fetal and neonatal hyperthyroidism as well as some rare forms of thyrotoxicosis in clinical practice. Accumulating evidence also indicates the possible correlation between thyroid cancer occurring in GD patients with positive TRAb and adverse outcomes. However, further innovation and standardization of TRAb tests are required to help pave the way for clinical applications.

Objective To construct eukaryotic expression vector of HPV18 L1- E6, E7 chimeric gene and examine the humoral and cellular immune responses induced by this DNA vaccines in mice. Methods The C-terminal of major capsid protein L1 gene and mutant zinc finger domains of early E6/7 oncogenes in HPV18 were integrated and inserted into eukaryotic expression vector pVAX1 to generate vaccines pVAX1-L1E6Mxx, E7Mxx. CHO cells were transiently transfected with the individual construct. Target protein expressions in the lysate of the transfected cells were measured by ELISA and immunocytochemistry. After BALB/c mice were vaccinated with various recombinant plasmids(pVAX1-L1-E6M3 or pVAX1-L1-E7M3) and immunie adjuvants (pLXHDmB7-2 or LTB) through different administration routes (intramuscular or intranasal) , the great cellular immune responses were produced as revealed by delayed-type hypersensitivity (DTH) and lymphocyte proliferation, and the expression of IL-4 and IFN- γ cells in CD4+ and CD8+subpopulations. Results The highly efficient expression of pVAX1-L1E6Mxx, E7Mxx vector in host eukaryotic cells were demonstrated both by ELISA and immunocytochemistry. The level of specific serum IgG against HPV in experiment groups mice was much higher than that of control group, and intranuscular immunization group had the highest antibody level. Intramuscular immunization groups were superior to intranasal immunization groups in DTH response, splenocyte proliferation and CD8+ IFN-γ + cells number, but CD4+ IL4+ cell number was higher in intranasal immunization groups. The immunization groups using pLXHDmB7-2 as adjuvant were superior to other groups in immunoresponse. Conclusion These DNA vaccines produce remarkable cellular and humoral immuneresponses in the mouse and may provide as prophylatic and therapeutic candidates for HPV induced cancer treatment.

BACKGROUND: Superficial fungal disease is one of the most common human infectious diseases. A recent clinical survey reported that more than half of patients with superficial fungal diseases might be infected at home. OBJECTIVE: The aim of this study is to investigate the correlation of the fungal infection between the patients and their family members. METHODS: Dermatologists of 71 general hospitals were involved and evaluated 7,323 patients and 1,037 their family members who were confirmed microscopically to have superficial fungal diseases. RESULTS: According to the survey results, 46.1% of the patients answered they might have been infected at home and 33.6% of the patients remembered there were other fungus-infected patients among their family members at the same time. The isolated organisms were Trichophyton rubrum (1686 cases, 80.9%), Trichophyton mentagrophytes (269 cases, 12.9%), Candida albicans (112 cases, 5.4%), Microsporum canis (12 cases, 0.6%), Trichophyton tonsurans (3 cases, 0.1%), Epidermophyton floccosum (2 cases, 0.1%). On the basis of the fungus culture, it was proven that 85.4% of the patients and their family members had the same kind of microorganism. CONCLUSION: As a result, we could conclude that there is a high possibility of transmitting the fungal infection from one family member to another.

PURPOSE: The metabolic parameters were compared with the 1st episode calcium oxalate urolithiasis in 3 age groups and according to gender. MATERIALS AND METHODS: A total of 167 patients (114 male and 53 female) with their 1st episode calcium oxalate urolithiasis, including 21 patients aged <30 years (group A), 99 aged 30-59 years (group B) and 47 aged 60 years (group C), were investigated by metabolic evaluation. The items of metabolic change evaluated were the low 24-hour urine volume (<1,500cc), hypercalciuria, hyperoxaluria, hyperuricosuria and hypocitraturia. RESULTS: A low 24-hour urine volume was more common in group A (46.6%) than groups B (24.2%) or C (23.4%). Hypercalciuria was more common in group B (16.2%, p<0.05) than groups A (0%) or C (2.1%). There were 14.3% hyperoxaluric patients in group A and 34.3% in group B, which was statistically significant (p<0.05). Of the 167 patients, 101 had hypocitraturia, but seemed to show no statistically significant difference between the groups. Hyperuricosuria was more common in group A (33.3%) than groups B (11.1) or C (2.1%). CONCLUSIONS: In patients with 1st episode calcium oxalate urolithiasis, hypocitraturia is the most common risk factor, regardless of age or gender. Hypercalciuria was more common in group B (age 30-59) than the other age groups, while low urine output and hyperuricosuria were more common in group A (age<30). Considering the significant differences in the various risk factors between the different age groups, the specific prevention and treatment of certain risk factors for calculus formations according to age and gender seem necessary.
