Objective To study the role of local immunity in the female genital tract with non- gonococcal urethritis(NGU).Methods Forty-four cervical secretions from patients with NGU were collected.After treatment with Azithromycin,22 cases were followed up.One month later,pathogen was eliminated in 15 patients.Another 27 un-infected people were included in our study.The level of secretory immunoglobulin A(SIgA)was detected using the automatic special protein analysor,and interferon-?(IFN-?)was quantified by enzyme-linked immunosorbent assay(ELISA).All data were analyzed with ANOVA.Results The levels of SIgA and IFN-?in NGU infected group were(34.29?15.92)mg/L and(97.13?24.00)ng/L respectively,while those of uninfected group were(47.57?19.61)mg/L and(120.71?33.78)ng/L,respectively(all P0.05).Conclusions SIgA and IFN-?secreted by genital tract mucosa may help pre- vent and resist the local NGU infection.However,the effect is limited,and is insufficient to eliminate infection completely and prevent reinfection.

ObjectiveTo observe the effect of comprehensive rehabilitation treatment on clinical nerve function deficiency (CNFD) and activities of daily living (ADL) of the patients with stroke. Methods45 stroke sufferers from different period were divided into three groups (1st group: in one month; 2nd group: one to six months; 3rd group: over six months). Before and after the comprehensive rehabilitation treatment was given, the CNFD, ADL and clinical effect were assessed.ResultsAfter comprehensive rehabilitation treatment, the CNFD of 1st group, and the ADL score of 1st group and 2nd group were improved significantly, and the 1st group's was better than the others. The total effective rate also increased in 1st and 2nd group. Conclusions Early rehabilitation treatment can improve the patient's neural motion function and the activities of daily living.

Sleep plays an important role in the modulation of endocrine function and energy metabolism;hormone levels are markedly different during a sleepless night compared with a night of normal sleep.Sleep deprivation may change the levels of cortisol,growth hormone(GH)and thyrotropin(TSH)at night.In addition,sleep curtailment disturbs the balance of anorexi- genic(leptin)and orexigenic(ghrelin)factors,and does harmful to glucose tolerance.

BACKGROUND:Previous studies have found that human platelet-derived growth factor-B (PDGF-B)-transfected gingival fibroblasts are capable of rapid proliferationin vitro, which can secrete platelet-derived growth factor BB proteins. OBJECTIVE:To explore the ability of PDGF-B-modified gingival fibroblasts in the acelular dermal matrixin vivo to form periodontal tissue engineering compound. METHODS: Gingival fibroblasts from Beagle dogs transfected with or without PDGF-B gene were implanted into the acelular dermal matrix. Cel growth on the acelular dermal matrix was observed. PDGF-B gene-transfected gingival fibroblasts/acelular dermal matrix composite (experimental group), gingival fibrobalsts/acelular dermal matrix composite (control group) and acelular dermal matrix (blank group) were implanted subcutaneously into the nude mice, respectively. At 2, 4, 8 weeks after implantation, skin tissues were taken and observed histologicaly. RESULTS AND CONCLUSION: PDGF-B gene-modified gingival fibroblasts and non-transfected gingival fibroblasts both grew and proliferated wel in the acelular dermal matrix. At 8 weeks after implantation, in the blank group, the surrounding cels largely entered into the acelular dermal matrix, but produce less new colagen fibers, and the cels only grew on the original colagen scaffold; in the control group, a great amount of colagen fibers formed, the original colagen fibers in the acelular dermal matrix were replaced by newly formed colagens, but the original colagen structure was reserved; in the experimental group, a large scale of permineralization formed, and mineralized nodes were arranged along the original colagen scaffold. These findings indicate that PDGF-B gene modified gingival fibroblasts can acquire osteoplastic abilities in the acelular dermal matrix in vivo.

Objective To investigate the activity of autologous pericardial patch treated by distilled water in right ventricular outflow tract reconstruction of tetralogy of fallot,and to evaluate its clinical effect. Methods The study used 125 patients who had applied correction surgery of tetralogy of fallot and autologous pericardial patch treated by distilled water in the right ventricular outflow reconstruction. 39 cases used fresh autologous pericardial patches,and 86 cases used autologous valved pericardial patch. The degree of insufficiency and activity of the pulmonary valve were compared. Results The mean follow-up time was ( 63 ± 8 ) months in fresh autologous pericardial patches group, while (55 ± 7) months in valved patch group. No significant difference was found in age, body surface area, heart rate, pulmonary artery diameter, cardiopulmonary bypass time and priming volume postoperative between the two groups. The exacerbations of pulmonary valve insufficiency and activity in fresh autologous pericardial patches group were significantly higher than in valved patch group. Conclusion Autologous pericardial patch treated by distilled water was beneficial in right ventricular outflow tract reconstruction of tetralogy of fallot. It reduced pulmo-nary valve insufficiency and sclerosis after the correction surgery and showed good mid-term clinical results .

Purpose　To investigate the diagnostic valuation of Gd-DTPA enhancement MRA in intracranial occuping and vescular diseases. Methods　Gd-DTPA MRA（63 cases）, MRA without Gd-DTPA（16 cases）as a control group was performed with Elscint Prestige 2.0T MR,MRA. 56 cases were proved by operation or pathology, 7 cases were proved by clinical observation. Results　The shape of aneurysms, the feeding arteries, the draining veins of AVM and diploe angioma, the feeding arteries of occuping were clearly showed by Gd-DTPA enhancement MRA and were not showed by MRA without Gd-DTPA.There wasn't much difference between cavernous angioma with Gd-DTPA enhancement MRA and MRA without Gd-DTPA in the shape and blood supply of cavernous angioma. Conclusion　Gd-DTPA enhancement MRA is useful and worthy for showing blood circulation of intracranial occuping and vascular diseases.

Objective To study immunologic mechanism of tiger's urine on patients of rheumatoid arthritis. Method We used ELISA method to detect TNF values of serum; we also used MTT colorimetric method to detect the inhibition of tiger's urine on T－ cell. Result TNF values of RA patient's serums at both active stage and stationary phase before the therapy were higher than those of healthy group; TNF values of patient's serums after the therapy were lower than those before the therapy; tiger's urine had obvious inhibitive action on proliferation of peripheral blood's T－ cell. Conclusion Tiger's urine could inhibit T－ cell's proliferation and TNF's secretion, which may be the important mechanism of curing RA.
