Objective To find out the incidence tendency and characteristics of bladder tumors during the past 28 yesrs in our institution. Methods The data from 1980 to 2007 were divided into three stages:1980-1989,1990-1999和2000-2007.Microsoft excel and SPSSl3.O were used to analyze the sex,age and histological types. Results There were 2350 cases of bladder tumors in 28 years.There were 92(66 males,26 females)cases of benign tumors and 2258(1788 males,470 females)malignant tumors,the incidence in male was 3.8 times higher than that in female.The cases of bladder malignant tumors increased,and the female increased faster than male.The peak age of incidence changed from 50-69 in 1980-1989 to 60-79 in 2000-2007.The average age of squamous cell carcinomas was 68 years,which was the oldest;and the average of paraganglioma was 35,which was the youngest.The age of urinary bladder carcinoma in 1980-1989,1990-1999 and 2000-2007 were significantly different(male:57.5±11. 7,62.6±12.3,65.9±11.3;female:58.7±13.6,60.75±12.1,65.85±12.0,respectively,P<0.05).In male,the age of squamous cell carcinomas was significantly different from the age of urothelial cell carcinomas and adenocarnomas(68.0±9.7 vs 59.85±14.1 and 63.4±9.9,respectively,P<0.05).Inverted papillomas were the most common bladder benign tumors;urothelial cell carcinomas were the most common bladder malignant tumors,and adenocarcinomas were the second,squamous cell carcinomas were the third. Conclusion The incidence of bladder malignant carcinomas in our institution increased and the female increased more quickly than male.

Objective To assess the feasibility of heterogeneous acellular dermal matrix(ADM)seeded with adipose derived stem cells(ADSC)for urethroplasty in a rabbit model.Methods ADSC were isolated from a rabbit and expanded in vitro,then identified by flow cytometry.We seeded ADSC onto the ADM and made it into tissue-engineered urethra.12 male rabbits were removed 1 cm urethra and divided into experiment group and control group.There were 6 rabbits in each group.Reconstructed urethra with tissueengineered urethra was used in experiment group,while unseeded ADM were used in control group.Urethrography was performed at 6 months after surgery.The animals were scarified at 3 and 6 months after surgery and the repaired urethra were harvested.H&E staining and immunohistochemical staining were performed with cytokeratin AE1/AE3 and smooth muscle desmin makers.Results The morphology of isolated ADSC was with long spindle cross-links,and had multicentral growth.Flow cytometry showed that the ADSC expressed CD166,CD105,CD90 and CD44,but not expressed CD45 and CD13.The cells could growth well on the ADM and showed good biocompatibility with it.All animals could void normally,urethrography showed there was no significant stenosis.3 months after surgery,the experiment group appeared regenerated smooth muscle but not in the control group,both groups did not regenerate urothelium.At 6 months urothelium and smooth muscle cells could be observed in the experiment group,but only the smooth muscle was evident in the control group.Conclusions By applying tissue engineering methods,we can seed the ADSC onto the heterogeneous ADM and make it into tissue-engineered urethra,which can help improve the reconstructive effect of urethra.

Objective:To explore the impact of clinical pharmacists involved in the treatment team on the reasonable drug use rate in medical orders. Methods:Totally 782 medical records including hypertension and 1-3 kinds of hypertension associated diseases in our hospital from January 2011 to December 2011 were used as the pre-intervention group, and 1 061 ones with the same conditions from September 2012 to August 2013 were used as the post-intervention group. The patients of the two groups were divided into 8 dis-ease subgroups, clinical pharmacists performed timely intervention on the medical orders in the post-intervention group, and the rational drug use rate between the two groups was compared. Results:In hypertension, hypertension associated coronary heart disease, hyper-tension with heart failure and hypertension with diabetes subgroups,the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 01), in hypertension with coronary heart disease and heart failure, hypertension associ-ated coronary heart disease and diabetes, hypertension with heart failure and diabetes subgroup, the difference in the rational drug use proportion before and after the intervention was statistically significant(P<0. 05), while in hypertension with coronary heart disease, heart failure and diabetes subgroups, the difference was not statistically significant(P>0. 05). After the medical records in the 8 sub-groups were aggregated, the difference in the rational drug use proportion before and after the intervention was statistically significant( P<0. 01). Conclusion:Clinical pharmacists should involve in the clinical treatment to intervene irrational drug use,which can signifi-cantly improve the medical record rationality, avoid the health risks as much as possible and ensure the medication safety and treatment effectiveness for patients.
