Objective To investigate the effect of xuebijing injection applied after abdominal operation on the inflammatory reaction,infection rate,length of stay and hepatorenal function. Methods Sixty patients received abdominal operations were randomly divided into therapeutic group (30 cases) and control group (30 cases). The inflammatory reaction indexes (temperature,heart rate,leucocyte) and hepatorenal function indexes(aminopherase, total bilirubin, creatinine, blood urea nitrogen) were observed in both groups before operation and after operation 3,7 days respectively. The infection rate and length of stay were compared in two groups. Results Temperature and leucocyte post operative 3 days [temperature:(37.0 ± 0.2) ℃ vs. (37.9 ± 0.4) ℃ ;leucocyte: (8.8 ± 1.1 ) × 109/L vs. ( 10.3 ± 1.7) × 109/L, P＜ 0.05] and length of stay in therapeutic group was obviously better than that in control group[ (8.7 ± 1.9 ) d vs. ( 10.9±1.6) d, P ＜ 0.05 ]. The hepatorenal function indexes and infection rate in both groups had no significant difference(P ＞ 0.05). Conclusion Xuebijing injection could significantly palliate the inflammatory reaction after abdominal operation, shorten the length of stay and has no hepatorenal toxicity in short term.

Objective: To assess the reliability and validity of the Chinese version of Swedish universities Scales of Personality(SSP).Methods: The Chinese version of SSP was administered to 204 undergraduate students of Shanghai.40 subjects were retested after 3 to 4 weeks.Results:The Cronbach's ? coefficients of all personality dimensions' subscales ranged from 0.63 to 0.82.The Cronbach's ? coefficients of the whole scale was 0.88.The test-retest coefficients ranged from 0.65 to 0.81(P

AIM: To investigate mutations of oncogene k-ras in colorectal cancer tissues and the relationship between mutations of k - ras and biological behavior of colorectal carcinoma. METHODS:The specimens of 123 patients with colorectal cancer were collected. Real - time fluorescence quantitative PCR were performed to detect k-ras mutations at codon 12 and codon 13 of exon 1, and the results were analyzed with the corresponding clinical pathological data. RESULTS: Among 123 colorectal cancer cases, point mutations were detected in 53 cases (40.8% ) , point mutations at codon 12 were found in 42 (34.1 % ) cases, and 11(8.9% ) cases at codon 13.No closely relationship between mutations of k-ras and tumor size, location, invasive depth and differentiation extent was observed. The rate of k-ras mutation in the cases with more invaded lymph nodes was higher than that in the cases without invaded lymph nodes ( P < 0.05 ) , and the rate of k-ras gene mutation in the cases with hepatic metastases was higher than that in no hepatic metastases (P <0.05). The rate of k - ras gene mutation was higher in TNM staging Ⅲ/Ⅳ than that in Ⅰ/Ⅱ( P < 0.05 ). CONCLUSION: Mutation of oncogene k-ras plays an important role in the carcinogenesis and development of colorectal cancer, and it is closely associated with invaded lymph notes and hepatic metastases, suggesting that mutation of k- ras indicates a poor prognosis.
