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 investigate the impact of nutritional risk of preoperative patients with different parts of colorectal cancer. Methods 385 cases of surgical patients diagnosed with colorectal cancer were selected in the retrospective study in April 2008 to March 2009, Gastrointestinal Surgery Center of West China Hospital in Sichuan University. Patients were divided into the right colon cancer group, the left colon cancer group, the rectal cancer group, using internationally recognized NRS- 2002 Scale and serum nutrition indicators to assess their preoperative nutrition. Results NRS-2002 score in the right colon cancer group showed higher than the left colon and rectal cancer group, but no statistical difference between the latter two rates; serum concentrations of HGB, TP, ALB, A/G were lower in the right colon cancer group than the other two groups, but the concentrations of ALT, AST, Ca2+, PO43-showed no statistical difference among three groups. Conclusions The proximal colon (right colon cancer) were more susceptible to the risk of preoperative malnutrition, the patients with different parts of colorectal cancer should be given to the corresponding preoperative nutritional assessment and nutritional support.

Objective:To probe into the long-term effect of La(NO3)3 fed orally on gast ric mucosa of rats.Methods:The gastric mucosa of rats was studied after La(NO3)3 was administe red orally for a long-term,by the use of ordinary histological technology and m orphometry.Results:In the groups of 20 mg·kg-1 and 10 mg·kg-1,the cytopl asma of more parietal cells lying in the top of the gastric gland was loose.Proporti on of cell types of the gastric gland was related to the doses. The acid mucus l evel of the mucous neck cells of male rats in the groups of 20 mg·kg-1 an d 10 m·kg-1 decreased. In the groups of 2 mg2kg-1, 0.2 mg·kg -1 and 0.1 mg*kg-1,the acid mucus level of the mucous neck cells of both male and female rats increased.Conclusion:La(NO3)3 fed orally for a long-term could injure gastric muc osa in higher dose (20 mg·kg-1,10 mg·kg-1) but promote the protect ive action of the gastric mucosa in lower dose (0.2 mg·kg-1,0.1 mg·kg- 1).
