Microsatellite instability (MSI) is an important molecular mechanism in colorectal cancer's initiation and progression,which has significant clinical significance.MSI is a diagnostic biomarker for Lynch synchrome.Moreover,the clinical implication of MSI testing extends to the role of prognostic marker and predictive maker,due to the better outcome of patients with MSI positive colorectal cancer and a general lack of response to chemotherapy employing 5-fluorouracil.

0.05);The expression of Survivin in hilar cholangiocarcinoma was closely statistically related with the expressions of PTEN and nm23.Conclusion:The expression of Survivin in hilar cholangiocarcinoma is significantly higher than that in tissues near carcinoma,suggesting its correlation with tumor;Survivin plays an important role in the oncogenesis and metastasis of hilar cholangiocarcinoma;Survivin is statistically related with PTEN and nm23 and detected together may helpful for diagnosis and prognosis of hilar cholangiocarcinoma.

Objective To explore drinking water pollution by algae in Wuhan. Methods Sampling was carried out in different kinds of tap waters and tank waters for algae detection and identification. Results The detection rate of algae in tap waters was 89% in tank water it was 86% and at the same spot the genera and number of algae in the tank waters increased by 37% and 60% compared with the tap waters respectively. Conclusion Drinking water has been polluted by algae in different degree in Wuhan.

Objective To investigate the pathogenesis of brain-type hemodialysis disequilibrium syndrome(DDS) in dogs with acute renal failure. Methods Seventy-two hours after bilateral ureteral ligation,12 uremic dogs were hemodialyzed for 2 hours,yeilding decreases in plasma urea from (66. 76?13.70) mmol/L to (17. 85?5. 84)mmol/L( P

Objective To observe the clinical efficacy of small-dose ranitidine hydrochloride and diphenoxy- late compositae in the combined treatment of diarrhea-predominant irritable bowel syndrome(D-IBS).Methods A prospective,randomized controlled clinical trial was designed.150 D-IBS patients according to RomeⅡcriteria were randomly divided into combined treatment group and control group.The combined treatment group(74 patients)re- ceived ranitidine hydrochloride,0.15g,each evening and diphenoxylate compositae,1 piece,each evening.The control group(76 patients)received diphenoxylate compositae,1 piece,rid.This study consisted of a 2-week baseline period, a 3-week treatment period,followed by a 2-week follow-up period.The main efficacy variable was assessed by per- ception of overall symptom during the previous weeks.Secondary efficacy variables included severity of diarrhea,ab- dominal pain and distention and other symptoms.Results After treatment of 3 weeks,the efficacy of the combined treatment group was better than that of the control group(x~2=5.10,P
