ABSTRACT

Objective To explore the features of recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) and the related factors.Methods 117 cases of LT for HCC were retrospectively analyzed in a single transplantation center,Medical School of Hanover between Nov 1993 and May 2006.The cumulative survival rates were calculated using the Kaplan-Meier method and the differences of the related factors between various groups were analyzed by Log-rank test.Results 63 cases (58.3%) met the Milan criteria,45 cases (41.7%) exceeded the Milan criteria.Those comply with and exceed The University of California,San Francisco (UCSF) criteria were 73 cases (67.6%) and 35 cases (32.4%),respectively.103 cases were cadaveric donor liver transplantation (CDLT) and 14 cases of living donor liver transplantation (LDLT) with no significant difference between the two groups in postoperative survival rate (P =0.911).Age(P =0.048),microvascular invasion(P =0.001),over UCSF criteria(P =0.013),and the grading of tumor differentiation(P =0.015) were major factors of tumor recurrence after transplantation.Conclusion Appropriate selection criteria,perioperative comprehensive treatment and effective control of recurrence are the keys for improving survival rate of liver transplantation recipients for HCC.

ABSTRACT

Colorectal cancer is currently the world's fourth incidence of malignant tumors,the early clinical manifestations are not obvious,so the early diagnosis is difficult to find,most of them are in progress.Treatment of advanced stage with chemotherapy,interventional therapy,radiotherapy and other methods,in which chemotherapy in the killing of tumor cells at the same time,the normal cells of the body also has a killing effect.In recent years,all kinds of new nano targeting delivery system has been developed,which can be targeted to the tumor tissue,so it is more and more important in the treatment of intestinal tumor,especially with metastasis.The author has made an overview of the types of nano drug carrier materials,the research status and its application in the research of colorectal cancer.

ABSTRACT

OBJECTIVE To understand the pathogens and their drugs resistance in general surgery department and provide rational suggestion of antibiotics use for clinic treatment.METHODS A total of 158 cases with nosocomial infection among the general surgery department inpatients from Jun 2006 to Oct 2008 were retrospectively analyzed and summarized.RESULTS The common nosocomial infection sites were the lower respiratory tract,gastrointestinal tract,urinary tract and surgical sites.The G-bacilli of nosocomial infections in turn were Escherichia coli(18.02%),Acinetobacter baumannii(11.26%),Pseudomonas aeruginosa(7.66%),and Klebsiella pneumoniae(4.50%).The main G+cocci were Staphylococcus aureus(21.62%),Enterococcus faecium(5.86%)and E.faecalis(3.15%)in turn.In G-bacilli,the sensitivity to imipenem was the highest from 58.82% to 100.00%.The sensitivity to amikacin were more than 70.00% except A.baumannii,and to sulbactam/cefoperazone were more than 50.00% except Pseudomonas aeruginosa.In G+ cocci,the sensitivity to vancomycin of S.aureus and E.faecium was 100.00% and 84.62%.CONCLUSIONS Investigating the pathogens and their drug resistance in general surgery department is very important to prevent and control nosocomial infections.

ABSTRACT

Hepatic resection is considered curative treatment for patients with hepatocellular carcinoma (HCC),but the range of indication is narrow. Liver transplantation(LT) is another option, but recurrence and metastasis reduce long-term and medium-term survival. Appropriate patient selection is crucial in ensuring acceptable outcomes. Novel anticancer agents (chemotherapy and molecular target therapy) and appropriate use of immunosuppressant hold promise for improving the outcomes.

ABSTRACT

Objective To investigate the effect of imbedding chemotherapy of sustained release of 5-fluorouracil on the healing of colonic stoma in dog. Methods Twenty-eight adult hybrid dogs were randomly divided into chemotherapy group (n=22) and control group (n=6). The canine sigmoid colon were firstly detached and then anastomosed via median abdominal incision, 200 mg sustained release of 5-fluorouracil was imbedded in the mesentery 1.0-1.5 cm away from colonic stoma in chemotherapy group, whereas the control substance was injected into the dogs in control group. Tissue samples were collected from mesentery and stomas on 3, 5, 7, 10 and 15 days after operation, respectively, in order to observe the healing of stoma. The drug concentrations in the stoma and in the tissues that were 0, 1, 3, 5, 7, 10 and 15 cm away from the imbedding point were also measured by high performance liquid chromatography method at different phases. Results The tissues from colonic stoma only showed inflammatory reaction at early stage, with no necrosis and cellular degeneration. It was observed that the stoma healed basically on the tenth day after operation. The drug concentrations in the tissues gradually decreased at the range of 0-15 cm over time, but all of which were higher than the anti-tumor effective concentration (0.10 ?g/g). Conclusion The imbedding chemotherapy of sustained release of 5-fluorouracil in mesentery has little effect on the healing of stoma, and it could remain an effective anti-tumor concentration in a period of time.

ABSTRACT

Purpose:To investigate the relationship between the expression tansforming growth factor ?(TGF ?) and the differentiation, invasion of colorectal adenocarcinoma.Methods:To observe the expression of transforming growth factor ? and transforming growth factor ? receptor in 68 samples of colorectal adenocarcinoma with immunohistochemical technique. Results:The cells with positive reaction of TGF ? antibody were scattered in the stroma. The cells with infiltrative growth had positive TGF ? staining.Conclusions:It was indicated that TGF ? might play an important role in the invasion and metastasis of colorectal adenocarcinoma.

ABSTRACT

Objective To explore the effect of norcantharidin (NCTD) on proliferation and apoptosis of implanted human gallbladder carcinoma in nude mice. MethodsGBC-SD cells of human gallbladder carcinoma were implanted subcutaneously into nude mice. Mice were randomly divided into control, 5-FU, NCTD and NCTD+5-FU -treatment groups. Tumor size, growth curve and inhibitory rate was respectively evaluated. Cell cycle and apoptosis were measured. Morphological changes of tumorous cells were observed. ResultsLD_ 50 of NCTD for nude mice was 139.96mg?kg -1. Tumor volume (5.61?0.39cm3 vs. 9.78?0.61cm3, P=0.000), percentage of the S phase cells (43.47%?2.83% vs. 69.85%?1.96%, P=0.000) in NCTD group was smaller than that in control group, with tumor inhibitory rate (42.63% vs. 0, P=0.012) and cell apoptosis rate (5.49%?0.59% vs. 15.08%?1.49%, P=0.000) being increased. Compared with other groups,the difference on tumor volume (4.51?1.11 cm3), tumor inhibitory rate (53.89%), percentage of the S phase cells (33.76%?2.39%) and cell apoptosis rate (18.68%?2.38%) in NCTD+5-FU group was statistically significant (P=0.000), with increased nuclear shrinkage, karyorrhexis and typical apoptosis. Conclusion NCTD inhibits the growth of implanted tumor of human gallbladder carcinoma in nude mice. The inhibitory effect could be intensified when combined with 5-FU.
