Objective:To study the effect of interleukin-18 on transdifferentiation in renal tubular epithelial cells(TECs).Methods:Human proximal tubular epithelial cell line(HK-2) was cultured in vitro.TECs were exposed to different concentrations(0,0.1,1,10 and 100 ng/ml) of IL-18 for 24,48 and 72 hours.At the end of each incubation,the expressions of the ?-SMA and TGF-?_1 mRNA were assessed by RT-PCR,the rate of ?-SMA expressing TECs was assessed by immunocytochemistry,and the expression of the ?-SMA protein was assessed by Western blotting.Results:(1)The expressions of ?-SMA and TGF-?_1 mRNA were increased significantly by a dose- and time-dependent manner when TECs were exposed to IL-18(P

OBJECTIVE: To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence. METHODS: The rat heroin dependent model was established by increasing intraperitoneal injection of heroin. DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group. RESULTS: DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time. CONCLUSION Heroin dependence can affect postsynaptic density of hippocampus, amygdala and frontal cortex. The changes become more apparent with extension of heroin dependence time.

Partial nature of "promoting blood circulation and dieresis" of Salvia Miltiorrhizain was initially demonstrated by investigating the regulation effect of AQP2 expression in kidney of trauma blood stasis model rats with the Salvia Miltiorrhizain so as to provide guidance for its clinical deployment of administration. Random allocation was taken to averagely divide 30 SD rats into two groups: 10 rats in normal group and 20 rats in blood stasis syndrome group. Trauma blood stasis rat model was established by quantitatively beating. Then the rat model group was divided into model group and salvia group. After 7 days of treatment, the rat kidney AQP2 expression was detected, the content of urine AQP2 was compared and the damaged local muscle and kidney pathological changes were observed by immunohistochemical method and western blot method. Compared with that of the normal group, rats in model group had inflammatory cells infiltration, blood stasis and edema of the injured local muscles and up-regulated AQP2 expression, decreasing urinary output, and kidney tissues blood stasis and edema (P < 0.05). On the other hand, compared with that of the model group, those parameters of rats in salvia group were all decreasing except urine output (P < 0.05). Such result indicated that Salvia Miltiorrhiza can reduce trauma blood stasis rat content of urine AQP2 and down-regulated AQP2 expression in kidney tissue, so as to reduce the reabsorption of water by renal tubular and increase urine output. The promoting blood circulation effect of Salvia Miltiorrhizain can alleviate the degree of the damaged tissue edema and encourage urine drainage. This therapy is closely related to the effect of regulating AQP2 in kidney by salvia, so the purpose of this study by verifying "promoting blood circulation and diuresis" as the mechanism for the regulation effect of the salvia on AQP2 expression.

OBJECTIVETo analyze the parameters of urodynamic tests for patients with type-III B prostatitis and evaluate the significance of the results of urodynamic tests in the choice of therapies for this disease.

METHODSUrodynamic tests were performed for 87 type-III B prostatitis patients aged 22-45 (30.7 ± 8.5) years, who had moderate or severe lower urinary tract symptoms (LUTS) and failed to respond to routine therapy. Different treatments were administered according to the results of urodynamic tests followed by observation of the therapeutic effects.

RESULTSUrodynamic abnormalities were found in 70 of the 87 patients, bladder outlet obstruction in 28 (32.2%), detrusor overactivity in 25 (28.7%), bladder hyperesthesia in 18 (20.7%), low compliance in 10 (11.5%), detrusor-external urethral sphincter dyssynergia in 1 (1.1%), and impaired detrusor contractile function in 1 (1.1%). Treatments achieved obvious effectiveness in 26 cases (29.9%), effectiveness in 51 (58.6%), and no effectiveness in 10 (11.5%).

CONCLUSIONUrodynamic tests contribute significantly to the choice of therapies for type-III B prostatitis patients with moderate or severe LUTS.

Objective To compare the predicted efficiency ofmacular hole closure index (MHCI) calculated by 2 different methods for postoperative anatomical outcomes after idiopathic macular hole (MH) surgery.Methods This is a prospective exploratory clinical study.A total of 63 patients (63 eyes) with idiopathic MH,who received vitrectomy,inner limiting membrane peeling and gas tamponade,were enrolled in this study.All the patients received optical coherence tomography (OCT) examination at each visit to measure the MHCI using the formula MHCI=(M+N) /BASE,M and N is the distance from outer limiting membrane break points to the beginning points of detached photoreceptor from retinal pigment epithelium of both side of the hole,respectively.BASE is the length of MH base.MHCI1 was measured by built-in caliper of OCT software,MHCI2 was measured by ImageJ software.The minimum macular diameter (MHD) was measured by built-in caliper of OCT software.Based on the OCT images,the anatomical outcomes were classified grade A (bridge-like shape closure),grade B (complete closure) and grade C (poor closure).Grade A and B are considered as good closure,grade C as poor closure.Patients were followed up at 3,6 and 12 months after surgery.The closure grades at last visit were the final outcome.The relationship between MHCI 1,MHCI2 and closure grades was analyzed.And the predicted efficiency of MHD,MHCI1 and MHCI2 for anatomical outcomes after the surgery was studied.Results The mean MHCI1 was 0.68±0.21 (0.30-1.35),MHCI2 was 0.95±0.26 (0.41-1.55),and MHD was (476.24±210.18) μm (127-956 μm).MHCI1 and MHCI2 were both negative correlated with the closure grades (r=-0.665,-0.691;P＜0.001).The receiver operating characteristic (ROC) curve analysis ofMHCI1,MHCI2 and MHD for the prediction of good or poor closure showed that area under the curve (AUC) was 0.928,0.957 and 0.916 respectively,and 0.505,0.67 and 559 μm were set as the lower cut-offvalue.The sensitivity was 96.2％,92.3％ and 90.9％ respectively,and specificity was 81.8％,72.7％ and 76.9％ respectively.Accordingly,the ROC curve analysis for the prediction of grade A or B closure showed that AUC was 0.840,0.847 and 0.653 respectively,and 0.705,0.965 and 364 μm were set as the upper cut-off value.The sensitivity was 80.0％,82.9％,63.4％ respectively and specificity was 75.0％,85.7％,65.9％.Conclusion MHCI1 and MHCI2,measured by built-in caliper of OCT software or ImageJ software,both have good predictive efficiency for the anatomical outcomes of MH surgery.

Objective To investigate the effects of a novel standardized training program on the satisfaction and training quality of general practitioners (GPs). Methods 114 GPs trained in Wuxi People's Hospital between 2009 and 2013 were included, 52 GPs and 62 GPs were trained before and after the reform respectively. The measures of teaching reform included improvements in curriculum provision, theory teaching, learning modality and skills training. The evaluation indexes of satisfaction questionnaire and examination were confirmed by literature method and small-group discussion. Self-report satisfaction ques-tionnaire were distributed to graduate GPs and valid questionnaires were collected, while the results of entrance examination and graduation examination of GPs were recorded before and after the teaching reform. The research data were analyzed by chi-square test using SPSS 16.0 software. Results The basic characteristics of GPs and results of entrance examination before and after the teaching reform were compa-rable (P>0.05), however, GPs' satisfaction with curriculum, theoretical education, study form and skill training were increased significantly after teaching reform (P<0.05). Besides that,the results of graduation examination of GPs after the teaching reform, both the theory and skill examination, were improved signifi-cantly (P<0.05). Conclusion The study showed that GPs satisfaction with training modality and the results of graduation examination were improved greatly through our innovative teaching reform.
