Objective To study the accuracy of plasma matrix metalloproteinase-9 (MMP-9) predicting hemorrhagic transformation (HT) in ischemic stroke. Methods The studies on plasma MMP-9 predicting HT in ischemic stroke were included, in which diagnostic criteria, methods, and subjects were clearly described, regardless of language of publication and type of studies. MEDLINE (Apr, 1966 to 2006), EMBase (Apt, 1966 to 2006), CNKI (Feb, 1977 to 2006), and wanfangshuju (1989 to 2005) were searched and the references lists of eligible studies were manually searched. Two reviewers independently evaluated the quality of studies and extracted data. The data were analyzed using the Revman 4. 2 or SPSS 11.0. Results Five trials including 497 patients fulfilled the inclusion criteria, 109 of the 497 patients developed HT. The heterogeneity among studies was great (xspecialty 89. 9% (95% CI: 86. 4%-93.5%), sensitivity 86. 5% (95% CI: 77. 3%-96. 8%). Conclusions The values of plasma MMP-9 may be an independent predictor of hemorrhagic transformation. The number of patients in the included studies is not large enough, and the results need to be confirmed in further studies.

Pseudomyxoma peritonei is a rare kind of clinical disease,mainly characterized by mucus exocrine cells grown in the peritoneum or omentum sticky which caused lots of jelly-like ascites.There is no obvious clinical specificity performance for pseudomyxoma peritonei,which is always misdiagnosed.By enhancing the awareness of pseudomyxoma peritonei,improving the relevant checks and reasonably extracting specimens for pathological examination can improve diagnosing rate of pseudomyxoma peritonei.Using complete cytoreductive surgery or major debulking surgery combined with intraperitoneal hyperthermic perfusion chemotherapy help to improve the survival of patients with pseudomyxoma peritonei.

Objective To compare the efficacy and influence on the immune function of oxaliplatin combined with tegafur gimeracil oteracil potassium capsule and mFOLFOX6 method in the treatment of gastric cancer with liver metastasis.Methods One hundred and thirty-four gastric cancer with liver metastasis patients who underwent treatment from Jan.2014 to Jan.2016 in Yulin First Hospital were selected as the participants and randomly divided observation group (67 cases) and control group (67 cases).The control group was treated by mFOLFOX6 method,while the observation group was treated by oxaliplatin combined with tegafur gimeracil oteracil potassium capsule.After treatment,the curative effects were evaluated.The life quality in each group as performed by KPS method before the treatment and in every period of treatment.Before and after the treatment,the levels of CD3 +,CD4 +,CD8 + and CD19 + were detected in two groups and the toxicity was compared.The SPSS 22.0 software was used to analyze relevant data,the measurement data was described by (x ± s) and using t-test,the enumeration data was described by percentage,using the Chi-square test.Results The total effective rate was 52.2％ in the observation group,higher than the 38.8％ in the control group (P ＜ 0.05).After the third and fourth course of treatment,the karnofsky perfomance status score were (81.3 ± 9.7) and (83.2 ± 9.9),were significantly higher in the observation group than which in the control group (P ＜ 0.05).After the treatment,the levels of CD3 +,CD4+,CD8+ andCD19+ were (54.21 ±6.38)％,(24.11 ±2.41) ％,(21.33±3.16) ％ and (7.18 ±1.13) ％ in the observation group,and higher than the control group (P ＜ 0.05).During the treatment,there were no serious toxicity occurs in the patients and the rates of toxicity were significantly lower in the observation group than which in the control group (P ＜ 0.05).Conclusion Oxaliplatin combined with tegafur gimeracil oteracil potassium capsule has a better effect and safety for therapy in the treatment of gastric cancer with liver metastasis than mFOLFOX6.

Objective To investigate the mechanism of ursolic acid-induced apoptosis in human leukemia cells.Methods U937 cells were exposed to ursolic acid(UA) at various concentrations for 6 h and 12 h,or at 20 ?mol/L for different time intervals.Cells were stained with Annexin V/PI,and their apoptosis was determined through flow cytometry.Total protein extracts were prepared and subjected to Western blot assay using antibodies against PARP,C-Caspase-3,C-Caspase-9,Mcl-1,Bcl-2,Bcl-xL,Bax,and Bad.Parallel studies were performed in human leukemia cell lines Jurkat and HL-60.Results Exposure of U937 cells to UA resulted in increase in apoptosis in dose and time-dependent manners.We found that UA-induced lethality was associated with Caspase activation and PARP cleavage,and that UA-induced apoptosis was proceeded by the downregulation of Mcl-1.Jurkat and HL-60 leukemia cells in parallel studies exhibited apoptosis after UA exposure similar to those observed in U937 cells,although HL-60 cells were less sensitive than U937 cells in UA-induced apoptosis,PARP degradation as well as Caspases activation.Conclusion UA induces apoptosis in human leukemia cells through a process that involves Mcl-1 downregulation,followed by Caspase activation and PARP degradation.

Murine interleukin-4 gene(mIL-4) was transfected into mice glioblastoma cell line G422 by recombinant adenovirus vector. We detected mRNA transcription of target gene in gene modified tumor cells(G422-mIL4). High level of mouse IL-4 could be detected in the culture supernatant of G422-mIL4. When inoculated subcuatneously, the tumor growth of G422-mIL4 was significantly inhibited as compared to wild type G422 and LacZ gene modified G422( G422-LacZ) . The period of survival of mice inoculated with G422-mlL4 was significantly prolongated(p
