Human cervical cancer oncogene(HCCR) is newly identified in cervical cancer tissues,and expresses in most human tumors. Resarches show that HCCR is a candidate marker for human hepatocelular carcinoma and breast cancer. Moreover,the expression of HCCR is regulated by mitogen-activated protein kinase (MAPK)and phosphatidylinositol 3-kinase signal pathway. The proliferation,apoptosis,migration and invasion of tumor cells could be inhibited by siRNA of HCCR.

Abnormal expressions of long non-coding RNAs (LncRNAs) are associated with a variety of tumors.Recent studies show that lncRNA can regulate other epigenetic processes such as DNA methylation,histone modifications,chromatin remodeling and miRNA through various ways;on the other side,other epigenetic processes can influence the expression of lncRNA.The mutual regulation of them paly important roles in the occurrence and development of malignant tumors.The better understanding of the crosstalk between lncRNA and epigenetic modulation will contribute to clearly clarify the mechanism of tumor,which provides a theoretical basis for the anti-cancer therapies targeting lncRNAs.

Objective To investigate the expression and significance of DLL4 in endometriosis.Methods 83 cases due to ovarian cyst surgery from December 2010 to September 2013,were selected in the Second Affiliated Hospital of Zhengzhou University,and were randomly divided into two groups in accordance with the random number table.Group A:48 cases were induded after staining from 83 patients who were tahen a part of cyst wall;Group B:of laparoscopic ovarian cyst surgery in 83 patients,37 cases of simultaneously hysteroscopy due to fertility requirements,exclude endometrial lesions,were taken reign uterine endometrium.The American fertility association revised standard (r-AFS)in 1985 was used to divide the clinical stage:Group A:21 cases of Ⅰ ~Ⅱ stage,27 cases of Ⅲ ~Ⅳ;Group B:16 cases of Ⅰ ~Ⅱ stage,21 cases of Ⅲ ~Ⅳ stage;Group C:30 cases hysteroscopic uterine septum resection with electricity due to lower mediastinal uterus were selected at the same period.The expression levels of DLL4 protein in Group A,B were detected by S-P method,and compared with the control group (Group C),then analyze its relationship with EMs stage. Results In Group A,B and C,the expression of DLL4 protein were (144.99 ±10.12 ),(1 15.42 ±10.39 ),(90.08 ±7.29 ),and there were significantly diffiences among three groups (F=314.220,P<0.05);The expression of DLL4 protein atⅠ~Ⅱstage were significantly lower than that inⅢ~Ⅳ stage (P<0.05).Conclusion DLL4 protein may play an important role in the pathogenisis of endometriosis.

The ecological balance of gastrointestinal microbiota plays an important role in digestion,absorption, metabolism,immunity and protection against pathogens. Functional disturbance of gastrointestinal microecology is closely related to gastrointestinal diseases. Recent studies have shown that gastrointestinal microecology was involved in the pathogenesis process of gastric cancer. This article reviewed the progress in study on relationship between gastrointestinal microecology and gastric cancer.

Objective To evaluate the early diagnostic value of cerebrospinal fluids (CSF) procalcitonin(PCT) for the post-neurosurgery bacterial meningitis (PNBM).Methods Conduct a prospective study in 34 patients who suspected PNBM in ICU of Kowloon Hospital of Suzhou.On the first day, all the patient blood samples were obtained for detection of routine blood count, C-reactive protein, PCT.Also, all the patient CSF samples were obtained for detection of routine CSF count, biochemical tests, PCT and for CSF culture.The patients were divided into PNBM group and non-PNBM group according to PNBM diagnostic criteria.Results Fifteen cases(44.12％) patients were diagnosed as PNBM,the other 19 cases were non infection group.Levels of CSF procalcitonin PCT 0.50 μg/L were significantly higher in patients with PNBM than those non-PNBM 0.29 μg/L on the first day(P＜0.01).The ROC curues indicated that the area under the curve (AUC) for CSF PCT was 0.846, it was significantly higher than the other traditional indicators' area.The cut off points of CSF procalcitonin was set to be 0.415 μg/L for patients with proven PNBM.The corresponding sensitivity, sepecificity were 80.0％ and 73.7％.Conclusion The level of the CSF procalcitonin may be valuable early diagnostic parameter for PNBM.Sensitivity and specificity of the CSF procalcitonin was higher than the other traditional indicators.

Objective To investigate the protective effects of pretreatment with low-dose ketamine on intestinal mueosa against ischemia-reperfasion injury (I/R) and the underlying mechanism. Methods Forty-eight male SD rats weighing 230-270 g were randomly divided into 6 groups (n = 8 each) : group Ⅰ sham operation (S) ;group Ⅱ ketamine + sham operation (KS);group Ⅲ l/R;group Ⅳ ketamine + I/R (K);groupⅤ ketamine + ZnPPⅨ + I/R (KZ) and group Ⅵ ZnPPⅨ + I/R. Ketaminc 10 mg/kg and/or ZnPPⅨ 5 mg/kg were injected intraperitoneally 30 min before I/R in group Ⅳ, Ⅴ and Ⅵ. Intestinal I/R was produced by clamping of superior mesentery artery for 1 h followed by 6 h reperfusion. The animals were then killed and a segment of small intestine of 2 cm in length at about 10 cm from ileocecal valve was removed for determination of MDA content and SOD activity, HO-1 and iNOS expression and histological examination. The degree of intestinal tissue damage was graded using Chiu's scoring system (0 = normal, 5 = severe damage-exfoliation of villi, disruption of proper lamina, bleeding and ulceration). Results Intestinal MDA content was significantly increased, SOD activity was decreased and HO-1 and iNOS expression was significantly up-regulated by I/R (group Ⅲ) as compared with group Ⅰ and Ⅱ . Ketamine pretreatment significantly attenuated I/R-induced increase in MDA content and decrease in SOD activity and the protective effects of ketamine against I/R were counteracted by concomitant asministration of ZnPPⅨ. Microscopic examination showed that the pathological changes induced by I/R were significantly attenuated by ketamine and the protective effects of ketamine pretreatment against I/R were reversed by ZnPPⅨ in group Ⅴ. Conclusion Low-dose ketamine pretreatment can significantly ameliorate intestinal ischemia-reperfusion injury and up-regulation of intestinal HO-1 expression and down-regulation of iNOS are involved in the mechanism.

Objective To investigate the effect of unfractioned heparin and low molecular weight heparin on expression of plasma hepatocyte growth factor(HGF)during percutaneous coronary intervention(PCI).Methods Seventy four patients with unstable angina pectoris were classfied into unfractioned heparin(UFH)group(n=49)and low molecular weight heparin(LMWH)group(n=25)according to the type of heparin used during PCI.The plasma levels of HGF were measured before,during,and after PCI in the patients.Results The plasma levels of HGF before procedure were of no statistical difference between the two groups.The levels of HGF were significantly increased during and after PCI in the unfractioned heparin and the LMWH group.Comparing with the pre-procedure level,the post-procedure level of HGF in the UFH group was 13 565.60?3 768.99 ng/L(vs 1 736.09?603.95 ng/L,P

The main spots of Ginsenoside Rg1, Ginsenoside Re, Ginsenoside Rb1, Schisandrin and Radix Ophiopgonis were identified by TLC method. Conclusion The preparation processes are stable. The method of quality control was showed rapid, reliable and well reproducible. It set a good basis for the compatibility study on Shengmai Injection in vivo.

Objective To seek an effective and safe therapy for acute variceal hemorrhage of patients with Child class C cirrhosis. Methods One hundred and nine Child class C cirrhotic patients with an acute hemorrhage from esophageal varices were reviewed. Sixty - one patients received medical therapy;29 patients were underwent sur- gical operations and 19 patients received TIPSS. Results The surgical group had a higher mortality rate during hos- pitalization(65. 5 % ) than either of the other groups(36. 1 % and 26. 3 % respectively ). The rebleeding rates during hospitalization were 24. 1 %, 36. 1 % and 15. 8 % respectively in the surgical group, medical group and TIPSS group. Rebleeding rate during following- up period were 33. 0%, 36. 1 % and 21 .4% respectively. The rebleeding rate was significantly higher in the medical group than that in either of the other groups during the two phases. Kaplan - Meier survival analysis didn' t show significant difference among the three groups. Conclusions The results showed that TIPSS is a good alternative to surgical or medical therapy for patients with Child class C cirrhosis and acute vericeal bleeding.
