Objective To observe the effect of ulinastatin on NT -proB -NP and Picco in patients with severe sepsis.Methods 50 patients with severe sepsis were randomly divided into the control group and observation group,25 patients in each group.The control group received the routine treatment,and the observation group received ulinastatin additionally.The venous blood was collected to determine cTn -I,NT -proBNP,TNF -αand Lac before treatment and 7 days after treatment.The APACHE Ⅱ and CFI were observed before treatment and 7 days after treat-ment.Results The differences of CFI,cTnI,NT -proBNP in the two groups before treatment were not significant (t =0.419,0.321,0.335,all P >0.05),after treatment,cTnI and NT -proBNP decreased more significantly(t =2.976,2.910,all P <0.05),while lifting more apparent CFI[(3.98 ±0.95)vs.(2.39 ±0.85),t =6.237,P <0.05]in the observation group than in the control group.The differences of TNF -αand Lac in the two groups before treatment were not significant (t =0.602,0.848,all P >0.05 ),after treatment,TNF -αand Lac decreased significantly faster in the observation group than in the control group(t =8.478,3.104,all P <0.05).After treat-ment,APACHE Ⅱ score decreased significantly in observation group than in the control group(t =2.321,P <0.05). Conclusion Ulinastatin had protective effects on heart function in patients with severe sepsis.

Objective　To explore the correlation between the expression of p33/ING1 and the clinicopathological features in patients with colorectal cancer, and to understand the possible mechanism of p33/ING1 in the oncogenesis of colorectal neoplasms. Methods　All samples of normal mucosa and cancer tissues from 52 patients with colorectal cancer were detected for their expression levels of p33/ING1 by RT-PCR. Results　A significant decrease in p33/ING1 mRNA expression was found in 30 out of 52(57.7%) colorectal cancer tissues. The results also showed that repression of p33/ING1 expression markedly related to both the Duke's stage and metastasis. Conclusion　Down-regulation of p33/ING1 may play an important role in the oncogenesis and development of colorectal carcinoma.

ObjectiveTo study the expression of ING1 mRNA and its mutation status in human colorectal cancer. MethodsSamples of normal mucosa and cancer tissues from 52 patients with colorectal cancer were detected for their expression of ING1mRNA with RT PCR, and screened for its mutation with PCR SSCP. The expression of p53 protein was detected with immunohistochemical staining.ResultsThe impaired expression of ING1mRNA in colorectal cancer was associated with an advanced Dukes′ stage and metastasis of lymph nodes ( P ≤ 0 01). The expression of ING1mRNA positively correlated to that of p53 protein ( P ≤0 01). And a infrequent mutation of ING1 was also observed. Conclusion Our results suggest that ING1 contributes to the tumorigenesis and progression of colorectal cancer through down regulating its expression rather than through mutation.

BACKGROUND: Overexpression of cancer suppressor gene ING1 may cause apoptosis of many kinds of cancer cells and results in cell cycle arrest in G1 stage. ING1 is involved in p53 signaling pathway and regulates the activity of p53 as a transcription-activating factor.OBJECTIVE: To explore the association of ING1 gene expression and mutation with the clinicpathological features of colorectal cancer.DESIGN: A controlled observation of the pathological samples.SETTING: Department of General Surgery, Southwest Hospital, Third Military Medical University of Chinese PLA.PARTICIPANTS: Totally 52 fresh colorectal cancer samples were obtained from patients hospitalized in the Southwest Hospital, Third Military Medical University of Chinese PLA from October 1998 to October 1999. Normal mucosal tissues were also collected 10 cm from the margin of the tumor during the operation. The patients included 29 male and 23 female patients with an average age of 50.28 years.METHODS: ING1mRNA and protein expressions were detected in the 52 colorectal cancer tissue samples. The ING1 gene mutation was detected by analyzing single-stranded DNA polymorphism. The expression of p53 protein in the colorectal cancer tissue was detected immunohistochemically.tion-single-strand conformation polymorphism.was obviously decreased in comparison with that in the normal mucosa(0. 626 ±0. 382 vs 1. 166 ±0. 245, P ＜ 0. 001) . The expression of ING1 in the tumor tissue of patients with lymphatic metastasis was significantly lower than that in the tumor tissues from patients without lymphatic metastasis (0. 393 ±0. 243 vs 0. 960 ±0. 299, P ＜0.01). The expression of p53 protein was positively correlated with ING1 mRNA expression( P ＜ 0.01). Only one of the 52 samples was positive for ING1 gene mutation.CONCLUSION: ING1 gene may participate in the occurrence and progression of colorectal cancer and its decreased expression inhibits the action of tumor suppressor genes. The decrement in ING1 mRNA and protein expression without gene mutation indicates that ING1 participates in the pathogenesis of colorectal cancer in a manner quite different from that of the classic tumor suppressor genes.
