Objective To study the effect of finasteride on preventing prostate hyperplasia with acute urinary retention.Methods Totally 626 patients with benign prostatic hyperplasia (BPH) were randomly divided into treatment group (316 cases) and control group (310 cases),followed up for 3 years.The incidence of acute urinary retention and prostate volume changes were analyzed.Results There were 3 cases of acute urinary retention in treatment group (1.0 ％),9 cases in control group (2.9％) (x2 ＝5.37,P＜0.05).In treatment group,the average prostate volume was reduced about 23.6％ compared with before taking the medicine,on the contrary,prostate volume was averagely increased 12.3％ in control group.Conclusions Finasteride can reduce the risk of acute urinary retention by narrowing the prostate volume in patients of benign prostatic hyperplasia.

ObjectiveTo study the feasibility,safety and efficacy of laparoscopic cyst excision and Roux-en-Y hepaticojejunostomy for adult congenital choledochal cyst.MethodA retrospective study was conducted on 7 adult patients with congenital choledochal cyst who received total laparoscopic cyst excision and Roux-en-y hepaticojejunostomy from May 2008 to February 2011 in the Department of General Surgery of Shengjing Hospital,China Medical University.ResultsAll the laparoscopic surgery was successful.The mean operation time was 210 minutes.The average intraoperative blood loss was 80 ml.All patients were out of bed within the first 24 h after surgery.The mean time to first flatus/bowel motion was 2.4 days.Except 1 patient who had small amount of bile leakage,all patients recovered smoothly without any major postoperative complications.The average hospital stay was 8.1 days.No patients suffered from abdominal pain,fever or jaundice during follow-up from 3 to 30 months.ConclusionTotal laparoscopic cyst excision and Roux-en-Y hepaticojejunostomy was a safe,efficacious,and minimally invasive procedure.

ObjectiveThrough the examination of Clostridium difficile (Cd) in the stool of inflammatory bowel disease (IBD) patients to investigate its infection status in IBD patients and the relationship with IBD.MethodsFrom December 2009 to January 2011,a total of 130 diagnosed IBD patients were collected in the Department of Gastroenterology,Ruijin Hospital,Shanghai Jiaotong University School of medicine,including 60 ulcerative colitis (UC) patients and 70 Crohn's disease (CD) patients.At same time.60 irritable bowel syndrome patients and 60 healthy volunteers were collected as control.Stool samples were tested by PCR and Cd toxin A/B test kit (CDTK).SPSS statistical software was used for statistical analysis.ResultsIn 130 enrolled IBD patients,16 cases (12.3％) were Cd infected,of which 10 were UC cases (16.7％) and 6 were CD cases (8.6％).No Cd infection was found positive in control group (x2 =15.779,P=0.000).The infection rate of Cd in the patients of active stage was higher than that in the patients of inactive stage (x2 =10.092,P=0.001).The infection rate of coion-type CD patients was 4/14,which was significantly higher than those of other types CD patients (x2 =13.125,P=0.001).The infection rate of Cd was 4.5％ in mild UC patients,14.3％ in moderate and 6/17 in severe (x2 =6.667,P=0.037) ; the infection rate were 0％ in mild CD patients,4.2％ in moderate and 5/16 in severe.The infection rate increased along with the increase of The disease severity (x2 =13.907,P=0.000).There was no significant difference in the infection rate of Cd between broad-spectrum antibiotics used and not used patients (x2 =1.414,P =0.378), or between patients with broad-spectrum antibioticsused aloneand combinedwith immunosuppressant (x2 =0.330,P=0.962).ConclusionsThere was certain infection rate of Cd in IBD patients,especially the patients in active stage. The infection rate increased along with the increase of the IBD severity.

Objective To analyze the common and individual training needs of palliative care among nurses in different level hospitals. Methods The self-designed questionnaire about training needs of palliative care was used to investigate 340 nurses in different level hospitals. The data were analyzed by Ridit analysis method. Results There were 24 important items and 26 unimportant items in the common training needs. Regarding the individual training needs,the concept of palliative care,basic nursing care and bereavement support were preferred by the primary-level hospital nurzes,while the principles of palliative care,basic nursing care and pain management in secondary-level hospital nurses,radiotherapy and chemotherapy care and the ethical and moral problems in palliative care in third-level hospital nurses. Conclusion Different level hospital nurs-es have beth common and individual needs in the training contents of palliative care. Ridit analysis can distinguish the differ-ences and provide reference for the training.

Education of medical morality is an important part of medical education and must be through the whole career life of medical workers.Now our society is in the period of transition,but education of medial morality fails to get enough attention.Based on the present situation,the paper first makes a systematic exposition of the importance,intension,element and process of the reception of medical morality education of medical workers,then points out the rule of this reception and the approach to realize the validity of medical morality education.

Objective To evaluate the clinical efficacy of Memotherm TM stent,a type of metallic stent in the management of secondary ureteropelvic junction obstruction. Methods From October 1995 to June 2001,13 cases (10 males and 3 females,mean age of 41 years) of secondary ureteropelvic junction obstruction underwent the Memotherm TM stenting.They were all followed up for an average of 26 months by B ultrasound,IVU,radionuclide renography and ureteroscopy. Results Of the 13 case,8 were cured,and 3 achieved improvement,while 2 cases failed.The main complications of endoprosthetic fibrotic stricture occurred in 5 cases.The forceps or YAG laser through ureteroscopy was used to remove the endoprosthetic fibrotic tissues. Conclusions Memotherm TM stent is mostly effective in the treatment of patients with secondary ureteropelvic junction obstruction,especially for patients who has undergone multiple operations or those are ineligible for open surgery.This procedure can significantly reduce the recurrence of ureterostenosis.

Objective To summarize the causes of failed drainage of double J ureteral stents following ureteroscopy. Methods From June 2000 to March 2003,the double J ureteral stents were placed for 3972 patients (2184 males and 1788 females)following ureteroscopy.The stents were placed through retrograde approach in 3138 cases,through antegrade approach in 1497 cases.The patients were followed up until the ureteral stents were retrieved. Results Of the 4635 cases,failed drainage of double J ureteral stent was found in 115 cases (2.48%).The main causes were severe extra luminal obstruction,serious steinstrasse,severe ureteral stricture and overperiod placement of ureteral stents. Conclusions Correctly identifying the indications for ureteroscopy and the placement of double J ureteral stents as well as close follow up are the keys to reduce the failure rate of drainage of double J ureteral stents following ureteroscopy.

Transient visual disturbance(TVD) is caused by artery stenosis,or artery embolism and migraine,which lead to reduction of eye blood flow,retinal ischemia and hypoxia.Major clinical manifestations include amaurosis fugax and visual transient ischemic attacks(TIA).The present research situation and progression of TVD were reviewed.

AIM:To analyze and compare the chemical constituents difference between single medicine decoction(SMD) and mixed medicine decoction(MMD) of Changweikang Granules. METHODS: TLC and HPLC methods were applied to comparing the chemical constituents in SMD and MMD of Changweikang. RESULTS: Spots of TLC between SMD and MMD similar,except for some difference in the HPLC. CONCLUSION: The analyses were carried out for the first time.We found that the plus of the chemical constituents in SMD equal to MMD of Changweikang,also during the course of MMD,new constituents may be generated.Based on these,we proposed that the material base of Changweikang were the rational preparation and complementation of the effective components and the generation of new constituents.
