BACKGROUND: Rheumatoid arthritis(RA) is an autoallergic disease,but its immunological pathogenesis has not been completely known. T lymphocytes, especially CD4+ TH1/TH2 cells, may have an important effect in the occurrence and development of RA.OBJECTIVE: To investigate the action of CD4+ TH1 and TH2 cells which separately mediate cellular immunity and humoral immunologic response (respectively) function in the occurrence and development of RA.DESIGN: Case-control, comparative observation.SETTING: Department of Immunology, Medical College of Chinese People's Armed Police Forces.PARTICIPANTS: Totally 15 patients with RA hospitalized in the Department of Internal Medicine of General Hospital of Tianjin Medical University between March 1999 and March 2000 were selected for a RA patient group, consisting of 2 males and 13 females. Of them, 12 patients whose serumal rheumatoid factor (RF)was positive and the three others' was negative. At the same time, 30 healthy individuals from persons receiving health examination in the hospital or from our department were selected for a healthy control group, consisting of 4 males and 26 females. Informed consents were obtained from the participants.peripheral blood mononuclear cells(PBMC) from the two groups of subjects were detected by enzyme-linked immunospot assay (ELISPOT). 200-500 lymphocytes were counted under a normal light microscope, and the perwhich secreted cytokines were detected by ELISPOT, and those which had red spots in their plasma after staining were positive cells. Among them,the cells secreting γ-interferon (IFN-γ) were Tm cells while those secreting interleukin-4 (IL-4) were TH2 cells. 200-500 lymphocytes were counted under a normal light microscope and the percentages of TH1 and TH2 cells square test were used for comparing statistical differences of data between the two groups.MAIN OUTCOME MEASURES: Quantitative analysis of T lymphocyte subsets (including CD3+ T cells, CD4+ T cells and CD8+ T cells) and CD4+ TH1/TH2 cells in peripheral blood from the two groups of subjects.RESULTS: Analysis of the results was from the study on all of subjects percentages of total T cells (CD3+ T cells), CD4+T cells and CD8+F cells in peripheral blood were not significantly different between the two significantly higher in RA patient group than that in healthy control group [(24.44±5.25)%, (14.93±3.82)%, P ＜ 0.05],while in RA patient group the percentage of TH2 cells and ratio of TH1 cells to TH2 cells from peripheral blood were not significantly different as compared with those of control group(P ＞ 0.05).CONCLUSION: Cellular immunologic function mediated by TH1 cells may be associated with the occurrence and development of RA.

Imaging data was analyzed by two senior radiologists to summarize its imaging featueres.Results Multiple hemangioblastomas (HGBLs)in cerebellum,spinal cord or brainstem were seen in all the patients.Flow void effect with varied degree was seen in the lesions.Dilated feeding and drainage blood vessels around lesions was seen in 6 cases.Multiple kidney and pancreas cysts were seen in all the patients.There were 4 cases with syringomyelia,7 cases with ocular retinal angioma,5 cases with renal cell carcinoma,2 cases with ground-glass-like lesions and micronodulars in lung.Conclusion VHL type Ⅰ has complex imaging performance.Ima-ging examination is important for early detection of VHL disease.

Objective:To describe our diagnostic and therapeutic experience of patients with urinary tract endometriosis.Methods:We performed a retrospective analysis of 22 cases of urinary tract endometriosis with histopathological results from 2001 to 2007.Results:The mean patient age was 36.0 years.Of the 22 patients,4 had bladder involvement and 18 ureteral involvement.In those with bladder endometriosis,the diagnosis was made by cystoscopy and biopsy in 4 patients.The treatments consisted of partial cystectomy in 3 patients and transurethral resection of the bladder in 1 patient.One of the patients who underwent transurethral resection of the bladder experienced 1 relapse.The relapse was treated with partial cystectomy.In the patients with ureteral endometriosis,the diagnosis was mainly established by ultrasound(18 cases),intravenous urography(11 cases),retrograde pyelography(7 cases),CT(14 cases) and MRI(5 cases).The treatments consisted of ureterolysis in 1 patient,ureteroneocystostomy in 4,and ureteral resection and end-to-end anastomosis in 13 of them.All the patients pathologic results were of endome-triosis.Conclusion:Urinary tract endometriosis is an uncommon disease.Partial cystectomy should be considered as the therapeutic option for bladder endometriosis.For cases of ureteral endome-triosis,the first technique depends on the location,extent and depth of the lesion.

Objective To investigate the effects of meliorated renal failure decoction (MRFD) on renal function and inflammatory cytokines in patients with CKD 3-4 stages. Methods Sixty-two patients with CKD 3-4 stages were divided into treatment group and control group through random number table method. Both groups were given conventional treatment of western medicine, and the treatment group was given MRFD additionally. After 6 months of treatment, the changes of TCM symptom scores, Hb, Scr, BUN, 24 h UP, IL-6, IL-8, TNF and eGFR were observed. Meanwhile, the clinical efficacy was evaluated. Results The total clinical effective rate in treatment group was 65.63%(21/32), and 30.00%(9/30) in the control group (P<0.01);the effective rate of TCM syndromes in treatment group was 96.88%(31/32), and 53.33%(16/30) in the control group (P<0.01). The symptoms were improved better in the treatment group than the control group except for the symptoms of dry mouth and throat, and diarrhea. The level of eGFR in treatment group increased obviously (P<0.05), while the levels of Scr, 24 h UP and BUN decreased (P<0.05, P<0.01), with statistical significance between the two groups ( P<0.01). The level of eGFR increased, and the levels of Scr decreased in the control group (P<0.01). The levels of IL-6, IL-8, and TNF in both groups were reduced, while the level of Hb increased in the two groups, without statistical significance (P>0.05). Conclusion MRFD can improve TCM syndrome and renal function, delay the progress of patients with CKD at 3-4 stage by means of reducing the inflammatory cytokines and inhibiting micro-inflammatory state.
