Objective To improve the treat effect of the orthotopic liver transplantation patients with severe sepsis. Methods Fif-ty-six post-surgery patients were enrolled in this study. Patients were divided into two groups. One was non-OLT group (A group) and the other was OLT group (B group). Besides general data, the surveillance of blood lactate, the number of failure organs, APACHE Ⅱand MODS were recorded. 28-days survival rate and follow-up were checked. Results The mortality of hospitalization in non-OLT group was 30% and 57.6% in OLT group. The level of blood lactate in OLT group at the 1 st day increased significantly, which was statistically differ-ent with that in non-OLT group (P <0.01). It decreased but kept higher than that in non-group in following seven days. The numbers of failure organs in OLT group were more than in non-OLT group (P <0.01). The continuous APACHE Ⅱ score had no significant difference between two groups. But the continuous MODS score in OLT group was higher than in non-OLT group (P <0.01). Conclusions The 28-days mortality of OLT with severe sepsis is almost two times as much as that of non-OLT. It should cause more attention. The OLT with se-vere sepsis is more likely suffered from failure organs and difficult to recovery. To assess the condition of failure organs in OLT patients with severe sepsis, MODS score is better than APACHE Ⅱ score in this study. It is suggested that the standard of score system could be improved or come up with new score for organ transplantation. It will be better if blood lactate score is included.

MTH1 protein can mitigate DNA damage which caused by reactive oxygen species through hydrolyzing oxidized deoxy-ribonucleoside triphosphate.MTH1 is highly expressed in various cancers, so as to maintain the viability of cancer cells.MTH1 is closely related to tumor associated genes such as microRNA,RAS gene and p53 gene.Moreover, MTH1 inhibitors can selectively suppress the proliferation of cancers,which is a potential new target in tumor therapy.

Objective To evaluate the curative effect of reoperation on postoperative recurrent hepatocellular carcinoma (HCC). Method From Jan.1995 to Dec. 1998, 18 recurrent HCC patients underwent 27 sessions of reoperation in our hospital. Result The mean interval between first and second operation among 18 patients was 39?14 months, and for the 9 cases, in which cancer recurred after second surgery, the mean interval between the second and the third operations was 21?4.5 months (P

Objective To explore the effect of applying Case-based study (CBS) in combina-tion with Reference-induced self education (RISE) in clinical teaching of Digestive endoscope diag-nostics. Method One hundred and twenty undergraduates in Grade 2012 of clinical imaging speciality of Beihua University were selected as the objects of study and classified at random into experiment group (60 students) and control group (60 students), In the course of teaching, the traditional LBL study and CBS-RISE study were separately employed, and examined through theoretical assessment in combination with case analysis, and the teaching effect in experiment group students was also evaluated through examination paper. SPSS 16.0 statistic soft ware was employed for data treatment and analysis, t test was used for quantity data and expressed as x±s, and x2 test for number counting data, and P<0.05 as the statistical significant difference. Results In experiment group, the total result, and the results of theoretical examination and case analysis were all superior to the control group, and the dif-ference between two groups exhibited statistical significance (P values respectively 0.008, 0.017 and 0.021). The excellent and good rate of the experimental group's theory examination score was 70%, which was higher than that of the control group (48.3%). The excellent and good rate of the experimen-tal group in the case analysis of examination results was 63.3%, higher than that of the control group (43.3%), and the difference was statistically significant (P values respectively 0.016 and 0.028). The students in experimental group showed better degree of satisfaction to the teaching model of CBS-RISE. In general, they considered that the CBS-RISE model could stimulate the learning interest of students, enhance the ability of analyzing and solving problems, deepen the understanding of knowl-edge, train a better clinical thinking model, and also develop a cooperative group idea. Conclusions CBS-RISE teaching model is feasible in the application of teaching in digestive endoscope diagnostics, and beneficial to the training of self learning ability and clinical consideration, deserving populariza-tion.

[Objective] To discuss the relativity between the deviation of nasal spetum and acute sinusitis ’offering relative theoretic base for clinical perven-tion, causa morbi, diagnosis and treatment.[Method] Select 1 case of deviation of nasal spetum from Hangzhou City First People Hospital, make pair com-parison 2 sides of the sinus, record the attack of 2 flanks of sinus with deviation of septum(frontal sinus, maxil ary sinus, frontal and back ethmoidal cellules, sphenoid sinus) for the sinusitis, and make quantitative analysis to the severity, evalulate susceptivity and severity. [Result] There ’s no difference of statistical meaning on the occurrence rate and sinusitis scores for the 2 flanks of the patient.[Conclusion]For such patient of acute sinusitis, the susceptivity and severi-ty are the same for 2 flanks of nasal cavity; the pure correction of the deviation can ’t effectively prevent or treat acute sinusitis; for such patient, we shal correspondingly evaluate and treat the compensatory change caused by deviated spetum.

CTL responses by autologous colorectal cancer cells were observed in five cases. The specific CTL was induced from two cases, in which tumor associated antigen, CA-Hb_3, was strongly positive. The CTL could not induced from other three cases in which CA-Hb_3 antigen was weakly positive. Weakly positive tumor cells in the three cases were loaded CA-Hb_3 antigen into cytoplasmas by the cationic liposomes and tested by immunohistochemical assay. The results showed that CA-Hb_3 antigen of tumor cells in two cases changed to strongly positive, and could induce CTL responses successfully. With blocking agents BFA and anti-MHC-I monoclonal antibody, CTL responses could be blocked. Our results suggested that soluble CA-Hb_3 antigen could enhance the immunogenity of colorectal cancer cells and induce effective anti-tumor cellular immune responses.

Purpose:To study the expressions and its clinical significances of bcl-2 and integrin?3 in human Non-small cell lung cancer(NSCLC)after radical surgical resection. Methods:Immunohistochemical (IHC) staining of bcl-2 and integrin?3 was performed on paraffin-embedded sections from 269 NSCLC patients who underwent surgery and were followed up for 1.1 to 122.2(median, 48.4) months postoperatively. Differences in survival rates and clinical characteristics were evaluated by SPSS10.0 statistical software packet. Results:The prevalence of bcl-2, integrin?3 and both these proteins expression in NSCLCs was 56.9%, 47.2% and 34.9%, respectively. Bcl-2 expression was seen more frequently in female NSCLCs and smaller tumors. Integrin?3 was seen more frequently in squamous carcinomas. Cox multivariate analysis showed that bcl-2 expression in stage Ⅱ NSCLC was an independent risk factor (5 years survival rate: 39.3% vs 52.1% P=0.04), and both bcl-2 and integrin ?3 positive in stage Ⅲa NSCLC are independent good factors(5 years survival rate: 34.5% vs 23.8% P=0.04). Conclusions:Bcl-2 and integrin ?3 are indicators of NSCLC biological behavior. Combined analysis of expression of these proteins in tumors may indicate the prognosis of NSCLC.

The absorption process is an important factor in determining the bioavailability of orally administered drugs. however, the absorption mechanism of many drugs is not clear. Caco-2 cell model is the best in vitro absorption model nowadays. It is widely used in the research on drug absorption process and absorption mechanism, especially in the aspect of traditional Chinese medicine absorption, the use of Caco-2 cell model has become the hot spot recently. Mo- reover, Caco-2 cell model is also applied in the research on drug metabolism. Therefore, Caco-2 cell model will become an important method in the research of drug absorption, and will be helpful to accelerate the process of new drug screening and development.
