Objective To investigate the functional and histological changes in aging gerbil bladders.MethodsTwelve male gerbils were randomly divided into control group and aging bladder group,with 6 in each group.Experiment was conducted in gerbils of control group and aging bladder group 6 months and 24 months after normal feeding,respectively.Urodynamic examinations including irrigation volume,compliance and filling pressure of bladder were performed,bladder weight was obtained,bladder weight index was calculated,morphological observation was conducted with HE staining,ratio of amount of smooth muscle to collagen was obtained with double immunohistochemical staining,and electron microscope was used to evaluate the ultrastructure of bladder.ResultsCompared with those in control group,the irrigation volume and compliance of bladder significantly decreased in aging bladder group(P0.05).However,the bladder weight index was significantly lower in aging bladder group(P0.05).There existed degeneration in smooth muscle cells and organelles in aging bladder group.ConclusionThe function of aging bladder in gerbils is impaired,which may be related to the degeneration of bladder tissues.

Objective To investigate the effects of human urinary kallidinogenase (HUK) on the abilities of spatial learning and memory and the expression of nestin in the peri-infarction cortex of rats after focal cerebral ischemia-reperfusion. Methods Sixty rats were equally randomized into 5 groups:sham-operated group, model group, low dose HUK treatment group (3.5 ×10-3 PNAU/kg), median dose HUK treatment group (8.75×10-3 PNAU/kg) and high dose HUK treatment group (17.5×10-3 PNAU/kg).The focal cerebral ischemia-reperfusion models in the model group and HUK treatment groups were established by introducing an intraluminal filament into the right middle cerebral artery of the rats. HUK was administered intraperitoneally right after the operation and afterward once daily for 2 weeks. The spatial learning and memory functions were studied by Morris water maze test, and the nestin expression in the peri-infarction cortex was measured by immunohistochemistry on the 15th d. Results The model group exhibited seriously spatial learning and memory deficits in both place navigation trail and spatial probe trial. In the place navigation trial, the mean values of escape latency in the median dose and high dose HUK treatment groups were shorter than those in the model group (P＜0.05). In the spatial probe trial, significant differences in the percentages of time spending in the former platform quadrant and frequency of crossing the former platform site were noted between the model group and both median dose and high dose HUK treatment groups (P＜0.05). Immunohistochemical analysis showed that the nestin expression in the peri-infarction cortex of median dose and high dose HUK treatment groups increased significantly as compared with that in the model group (P＜0.05). Conclusion Treatment with HUK improves the spatial learning and memory abilities in rats after focal cerebral ischemia-reperfusion, which may result from the increasing expression ofnestin and the proliferation of neural stem cells.

Methods The questionnaires were administered,including complaints of LUTS,International Prostate Symptoms Score(IPSS) and quality of life assessment.Meanwhile,uroflowmetry was performed and volume of residual urine was measured. Results The total number of women surveyed was 359.According to IPSS,the prevalence of moderate to severe LUTS(IPSS≥8) was 39.0%.The prevalence in those with age of 50-59,60-69 and ≥70 years were 35.1%,46.2% and 54.8%,respectively(P=0.034).Of all the women surveyed,73.8% had predominantly irritative symptoms.The maximum flow rates(Qmax)were(24.5?11.5) mL/s,(22.7?11.0) mL/s and(14.5?8.2) mL/s,respectively for these age groups(P

BACKGROUNDBenign prostate hyperplasia is one of the most common diseases affecting the health of the aging males. Watchful waiting is an acceptable management strategy for benign prostate hyperplasia in which the patient is monitored by the physician but receives no active intervention. The epidemiological data on this are lacking in China. Our study was designed to evaluate the changes of signs and symptoms of patients with benign prostate hyperplasia during management by watchful waiting in China.

METHODSOne hundred and forty-five patients with benign prostate hyperplasia aged > 50 years were enrolled in management by watchful waiting. All the patients were visited every 6 months and were given an International Prostate Symptom Score and Quality of Life questionnaire to complete. They also had uroflowmetry and were assessed using ultrasonography to get the volume of prostate, transition zone and amount of residual urine. The Student's t test, the Chi-square test, and variance analysis were used in the statistical analysis.

RESULTSAll patients were visited after 6 months, the mean volume of transitional zone was found to have increased by 1.6 ml (P < 0.01), International Prostate Symptom Score was increased by 0.8 (P < 0.01) and Quality of Life was increased by 0.2 (P < 0.01), and there was no statistical change in other data. Among these patients, 17.9% (26/145) visited again after 12 months when the data failed to show a statistically significant difference among the three groups (0, 6, and 12 months).

CONCLUSIONSAfter one year's follow-up, the progression of benign prostate hyperplasia was slow and the clinical data did not undergo much change.

Objective To explore the expressions of matrix metalloproteinase-9 (MMP-9) and tissue inhibitors of matrix metalloproteinase-1 (TIMP-1) after focal cerebral ischemia-repeffusion injury in rats. Methods Totally 40 Wistar rats were randomly divided into 2 groups: sham-operated group and iscbemia-reperfusion group. A middle cerebral artery occlusion model was constructed in the 25 rats with Longa's method. The expressions of MMP-9 and TIMP-1 were investigated with immunohistochemistry and HE staining at 6, 24, 48, 72 h and 7 d of reperfusion following 2 h ischemia. Results MMP-9 began to be expressed at 6 h reperfusion, and was obviously increased at 24 h and reached the peak level at 48 h, and then, the expression of MMP-9 began to decrease at 72 h to a low level at 7 d. TIMP-1 positive cells began to arise at 6 h reperfusion, peaked at 24 h, decreased at 48 h and remained a low level at 7 d. The expressions of MMP-9 and TIMP-1 were mainly located in vascular endothelial cells, neurons and gitter cells. The expressions of MMP-9 and TIMP-1 were negative in sham-operated group. Conclusion The expressions of MMP-9 and TIMP-1 are induced to increase by focal cerebral ischemia-reperfusion, and vascular endothelial injury may be the main cause to the high expressions of MMP-9 and TLMP-1.

Objective To evaluate the efficacy and safety of stenting on symptomatic severe M1 segment stenosis (>80% lumen reduction) of the middle cerebral artery. Methods Thirty-two patients with symptomatic severe M1 segment stenosis of the middle cerebral artery, admitted to our hospital from July 2007 to August 2010, were included in this study. These patients were diagnosed by cerebral angiography and treated using balloon-expandable stents. Their clinical data were collected; the success rate of the treatment, perioperative management and complicatious, stroke during the follow-up period and reangiostenosis were further discussed. Results The success rate was 93.8% (30/32) for total lesions. During the perioperation, 2 patients had cerebral infarction and one of them was asymptomatic ischemic stroke; no other complications appeared. No recurrence of ischemic stroke or death appeared in these 32 patients during the mean 12.6 months of follow-up. Conclusion Stenting based on drug treatment appears to be an effective and feasible therapy for symptomatic severe M1 segment stenosis of the middle erebral artery, but also appears to have the perioperation complication.
