Transient receptor potential(TRP)channels as an important non-selective cation channels family mainly permeate Ca2 + ,Na + and other cations. TRPC channel is a subtribe of TRP family which regu-lates the second messenger of Ca2 + concentration and variety of protease activity,and which can directly or in-directly affect the biological behavior of cells. Recently,more and more evidences have certificated the TRPC channels affect the tumorigenesis and development,such as regulation of proliferation,differentiation,migra-tion,apoptosis and resistance of chemotherapeutic agents during cancer progression.

Objective To explore the effect of type 2 diabetes mellitus(T2DM) on vascular damage characteristics of acute cerebral infarction and the impact on the short term prognosis.Methods One hundred and fifty-six cases of acute cerebral infarction patients were selected and divided into the T2DM group with 64 cases and non-T2DM group with 92 examples.According to the whole cerebral angiogram,the results and the results of the treatment of acute cerebral infarction and prognosis were analyzed.Results The incidence of intracranial artery stenosis of the T2DM group was 79.69％ (51/64),of non-T2DM group was 58.70％ (54/92),the difference between two groups was significant(x2=12.856,P＜0.05).The incidence of before andafter intracranial artery stenosis coexist,circulation narrow coexist in T2DM group was 50.00％ (32/64),59.36％(38/64) respectively,in non-T2DM group was 21.74％(20/92),29.35％(27/92) respectively,the difference between groups was significant(x2 =9.652,8.659;P＜0.05).The incidence of multivessel lesions and diffuse lesions and without collateral compensatory in T2DM group was 71.88％ (46/64),65.63％ (42/64) and 71.88％(46/64) respsctively,in non-T2DM group was 54.35％(59/92),39.13％(36/92) and 31.52％(29/92) respectively,thedifference between groups was significant(x2=8.625,9.354,11.053;P＜0.05).The total effective rate after 2 weeks of treatment in T2DM group was 46.88％(30/64),in non-T2DM group was 90.22％(83/92),the difference between groups was significant(x2=8.061,P＜0.05).Conclusion The incidence of intracranial artery stenosis in patients with intracranial artery stenosis combined with T2DM is higher than the control group,and lesion range widely,diffuse damage,vascular damage moderately severe stenosis and occlusion are significantly higher than in non-T2DM group,especially without collateral compensatory rates is higher than non-T2DM group,while the neural function damage of T2DM group is heavier and poorer prognosis.

Patients with ischemic stroke is often accompanied by inflammtory response. Studies have suggested that toll-like receptor 4 (TLR4) has induced the occurrence,development and of ischemic stroke and secondary brain injury. This article reviews the toil-like receptor 4 signal transduction pathway and its roles in ischemic stroke in order to provide certain basis for the development of TLR4-targeted medication.

Objective: To evaluate the impact of the number of negative lymph nodes on disease free survival (DFS) of patients with locally advanced gastric cancer. Methods: A total of 485 patients who underwent surgery for gastric cancer were enrolled in this study. We analyzed the data of these patients including complete information of follow-up and definite postoperative pathological results. The disease free survival of all patients was more than 6 months and was analyzed according to the pathological stage respectively. COX regression analysis was performed to screen the independent prognostic factors. Kaplan-Meier method was used to draw the disease free survival curve and the disease free survival rate was compared among subgroups. Results: Cox regression analysis showed that the disease free survival rate of gastric cancer patients with pathological stage T_3N_(0～2)M_0 was significantly associated with age, degree of tumor differentiation, tumor location as well as the number of negative lymph nodes. In the T_3N_0M_0 subgroup, when the number of negative lymph nodes was 1 to 4 and 5 or more, the 2-year disease free survival rate was 8.3% and 55.6%, respectively, and the 3-year disease free survival rate was 0 and 24.9%, respectively (P=0.025).In the T_3N_1M_0 subgroup, when the number of negative lymph nodes was 3 or less, 4 to 9, and 10 or more, the 2-year disease free survival rate was 17.3%, 39.1%, and 52.6%, respectively, and the 3-year disease free survival rate was 4.2%, 6.0%, and 17.1%, respectively (P<0.001). In the T_3N_1M_0 subgroup, when the number of negative lymph nodes was 7 or less and 8 or more, the 2-year disease free survival rate was 11.5% and 35%, respectively, and the 3-year disease free survival rate was 0.8% and 5%, respectively (P=0.015).Conclusion: For gastric cancer patients with pathological stage T_3N_(0～2)M_0, the number of negative nodes could reflect the level of regional lymph node dissection. The number of negative nodes can be an index for evaluation of the accuracy of pathological staging and is considered as an independent prognostic factor for disease free survival of gastric cancer patients.

Objective To observe the influence of Zhibai Qianqing(ZBQQ) Decoction combined with Levofloxacin on sperm quality of chronic prostatitis(CP) patients and explore its possible mechanism through sperm apoptosis rate.Methods Fifty eight cases were divided into 2 groups randomly.Twenty eight cases were served with ZBQQ decoction combined with Levofloxacin(observe group),30 cases were treated by Levofloxacin tablets(control group).The curative effect of the two groups was compared one month later.All the cases underwent semen analysis.Sperm apoptosis rates were measured by TUNEL before and after the treatment.Results Sperm liquefaction time of CP group was significantly longer than the normal group(P0.05).The clinic cure rate of observe group was 35.71%,and overall effective rate was 85.71%,significantly higher than that of control group(P

Objective To investigate the relationship between 5 ,10-methylenetetrahydrofolate reductase (MTHFR) gene C677T locus polymorphism and unexplained adverse pregnancy.Methods Three hundreds and twenty pregnant women with unknown ad-verse pregnancy ≥ 2 times in the infertility department ,and obstetrics and gynecology department of our hospital from June 2014 to May 2016 were selected as the case group and 388 healthy non-abortion parous women were taken as the control group.The MTH-FR gene C677T locus polymorphism in the two groups was analyzed by using gene chip method.The differences in genotype and al-lele frequency distribution were compared between the two groups ,and the relationship between unexplained adverse pregnancy and MTHFR C677T locus polymorphism was analyzed.Results The frequency distribution of MTHFR genotype C677T C/C had sta-tistically significant difference between the case group and control group (P<0.05 ,OR=0.284).The frequency distribution of gen-otype C/T had no statistical difference between the case group and control group (P=0.400 ,OR=1.140).The frequency distribu-tion of genotype T/T had statistical difference between the case group and control group (P<0.05 ,OR=7.672).The frequency distribution of allele C and T had statistical difference between the case group and control group ( P< 0.05 ,OR= 0.304 ). Conclusion The high expression of MTHFR C677T genotype T/T may be a risk factor of unknown adverse pregnancy in child-bearing age women.

Objective:To investigate the clinical efficacy of every 3-week regimen of oxaliplatin (OXA) plus 5-fluorouracil (5-FU)/leucovorin(CF)as postoperative adjuvant chemotherapy for colorectal cancer.Methods:Ninety eight patients with stage Ⅱ to stage Ⅲ colorectal cancer received every 3-week OXA plus 5-FU/CF adjuvant chemotherapy for six cycles after resection surgery. All the patients received a complete reexamination every 3 months after the end of adjuvant chemotherapy. The disease-free survival period and 1- and 2-year disease-free survival rates were observed.Results:The total 2-year disease-free survival rate was 74.5%. It was 87.0% for stageⅡpatients and 63.5% for stage Ⅲ patients. The main adverse reaction included peripheral neurotoxicity, neutropenia and diarrhea at grades Ⅰ to Ⅱ. Grades Ⅲ to Ⅳ adverse reactions occurred rarely.Conclusion:The every 3-week OXA combined with 5-FU/CF adjuvant chemotherapy regimen had definite efficacy and good tolerance, which was a rational choice of postoperative adjuvant chemotherapy for colorectal cancer.
