1.Roles of transient receptor potential canonical channels in tumors
Journal of International Oncology 2015;(7):522-524
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.

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.

Two lipase active fractions Lip1 and Lip2 were purified from the cell extract of Rhizopus chinensis CCTCCM201021.Both gave a single band on SDS-PAGE after using ammonium sulfate precipitation、Phenyl-Sepharose FF、DEAE-Sepharose FF and Sephadex G100 gel filtration chromatographies.The molecular masses of two lipases were 59.2kD and 39.4kD respectively.Lip1 and Lip2 showed optimal pH at 8.0 and 8.5 and their optimal temperatures were 40℃ and 35℃ respectively.The substrate specificity of the two lipases was obviously different.Lip1 was more specific to long chain fatty acid of p-nitrophenyl esters while Lip2 had a preference for the hydrolysis of short chain fatty acid of p-nitrophenyl esters.Lip1 had 1,3-position specificity for triacylglycerols hydrolysis while Lip2 had nonspecific position.Both lipases were stimulated by Ca 2+、Mg 2+ while SDS had strong inhibition on their activities.Lip1 and Lip2 had good stability in cyclohexane、hexane、heptane and isooctane(30% V/V).
8.Association of the Number of Negative Lymph Nodes with Prognosis of Post-operative Gastric Cancer Patients
Chinese Journal of Clinical Oncology 2010;37(2):101-103,107
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.
9.Clinical observation on every 3-week oxaliplatin plus 5-FU/CF regimen as postoperative adjuvant chemotherapy for colorectal cancer
Tumor 2009;(12):1167-1169
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.

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
