In 2015 , policy reforms on centralized drug purchasing system have been released one by one , and the quality of medicines has been highly valued .Centralized drug purchasing system distinguishes different qualities of drugs mainly through bidding grouping , in order to achieve “uality priority”.However , there are yet some existing problems in group bidding policy at present , such as lack of a unified hierarchy , no scientific indicators and so on , which inevitably weaken the leading role of centralized purchasing policy over the quality of medicines .This paper , focuses on the study of group bidding , and the existing main problems are found through the statistical analysis of rel-evant policies introduced in different provinces .Finally, it explores some optimization strategies for “Group Bidding”which is of paramount importance .

Objective: To summarize the typical experiences and practices based on the quality evaluation of medical consumables in foreign countries and the practice of drug bidding in China,and to explore the establishment of a bidding grouping scheme for medical consumables in China. Methods: Using literature analysis and evaluation method of combing foreign countries typical measures of medical consumables quality assessment,this paper summa-rized the construction of index system of bidding in China Pharmaceutical Group, and used simple statistical data to reflect the present policy of China's medical supplies such as lack of relevant policies,different levels of quality etc.. Results:There are many problems in the quality evaluation of medical consumables in China. However, the typical measures of extraterritorial quality evaluation and the practice of pharmaceutical bidding in China provide a solid theo-retical and practical basis for the establishment of medical consumable supplies bidding grouping. Conclusion:Estab-lishing bidding grouping scheme is necessary in the Chinese Medical supplies context. Based on a clear difference be-tween medical supplies and medicines,and according to the"three stage"our conceptualization gradually improved. On the basis of the existing data and practical situation,the establishment of scientific selection index bidding group division standard,has been in the exploration of the formation of China's medical supplies bidding grouping scheme.

Objective To test whether glucagon like peptide-1 (GLP-1) would regulate the expression of visfatin in adipocytes,and to explore the mechanism of this effect.Methods Fully differentiated 3T3-L1 adipocytes were treated with GLP-1.Total RNA was extracted for analyzing the level of visfatin mRNA by quantitative RT-PCR.The media were collected for measuring the level of visfatin protein by enzyme linked immuno-assay (ELISA).In order to test the involvement of PKA pathway,the adipocytes were pretreated with a specific pharmacological PKA inhibitor H89 for 30 min before GLP-1 was added.Results GLP-1 increased visfatin expression in a time-and dose-dependent manner.The level of visfatin significantly increased at the concentration of 10 10 mol/L GLP-1 (P＜0.05),and reached the peak at 10-9 mol/L (P＜0.01).After incubation for 18 hours,GLP-1 dominantly increased the level of visfatin (P＜0.05).Inhibition of PKA pathway by H89 partially blocked the effect of GLP-1 on visfatin expression.Conclusions GLP-1 may enhance the expression of visfatin in 3T3-L1 adipocyte via the PKA pathway,which might contribute to the improvement in glucose homeostasis.

Objective To investigate the relationship between polymorphism of NAD (P)H quinone oxidoreductase 1 (NQO1)and X-ray repair cross-complementing group 1 (XRCC1) and their correlation with smoking on the susceptibility to gastric cancer. Methods A 1:1 case-control study of 334 patients with primary gastric cancer, with non-cancer or alimentary inpatients as control group (matched for ages ± 5 years, sex and reqion) in Anhui province was conducted to analyze theNQO1C609T and XRCC1G28152A. Gene types by PCR-based restriction fragment length polymorphism techniques. Interaction index (γ) was calculated to determine the type of gene- environment interaction. Results The average age of 334 cases of gastric cancer patients was 57 years, with 65.3% of them were male. Smoking rate in the case group (55.09%) was significantly higher than in the control group (36.53%). The consequence showing that it carried the heterozygous variant (CT)or homozygous variant (TT) of NQO1 could enhance the risk of gastric cancer(OR= 1.507,3.050),but not the XRCC1G28152A gene polymorphism or the susceptibility to gastric cancer. At the same time,individuals that carrying XRCC1AG and NQO1TT could increase 2.789 times the incidence of gastric cancer than those who carrying the XRCC1AG or NQO1CC. The gastric cancer risk of XRCC1GG individuals that carrying NQO1TT was 4.448 times higher than those who carrying XRCC1GG or NQO1 CC. The positive interactions of NQO1 homozygous variant (TT) , XRCC1 homozygous variant (GG) and smoking were revealed in the occurrence rates of gastric cancer (OR=3.094,γ =2.070). Conclusion Our research findings showed that the significant interactions between genetic polymorphisms of NQO1, XRCC1 and smoking added the risk of gastric cancer, while genetic and environmental hazardous factors co-effecting the development of gastric cancer.

Most drugs need to interact with cell membrane to reach the biological target, so that membrane affinity assay is an important early screening step in drug discovery. However, at present, the traditional oil-water distribution method is still used, a new, simple and accurate method for membrane affinity assay is urgently needed. In this study, according to the colorimetric principle, a new assay model based on polydiacetylene vesicles was optimized through a series of experiments including different concentrations of vesicle solution, temperature, or pH reaction environment. On this basis, tetracaine hydrochloride, 2-methylimidazole and histamine were used as model drugs to measure the membrane affinity constants and verify the between-batch precision of the optimized assay model (relative standard deviation less than 5%). In addition, polydiacetylene vesicles were stable for up to 180 days, demonstrating the potential application of the assay model. This strategy is simple, stable, reliable, with high reproducibility, low cost and easy to promote, which provided a new tool and a new direction for the high-throughput assay of membrane affinity.

Objective:To explore the clinical value of laparoscopic abdominoperineal resection(LAPR) with pelvic peritoneum closure for patients with low rectal cancer.Methods:The clinicopathological data of 90 patients with low rectal cancer who underwent laparoscopic abdominoperineal resection from Mar 2014 to Jan 2019 at the Subei People's Hospital of Jiangsu Province were retrospectively analyzed. These patients were divided into closed pelvic floor peritoneum group (study group, n=42) and without pelvic floor peritoneum group (control group, n=48) . Results:The postoperative hospital stay of the study group was shorter than that of the control group[(10.8±3.0) d vs. (12.4±3.1) d, t=2.569, P=0.013]. There was no statistically significant difference in the operation time , intraoperative blood loss , time to first flatus ,first time of getting out of bed between the two groups. Perineal incision infection and perineal incision dehiscence occurred in 2 cases and 1 case in the study group, and 10 cases and 9 cases in the control group respectively (χ 2= 5.007, P=0.025; χ 2=6.077, P=0.033). In the study group, there were 0 cases of perineal hernia, 1 case of pelvic floor peritoneal hernia and 2 cases of adhesive intestinal obstruction, while those in the control group were 7 cases, 8 cases and 9 cases, respectively (χ 2=6.642, P=0.013; χ 2=5.079, P=0.033; χ 2=4.085, P=0.043). Conclusion:Laparoscopic abdominoperineal resection with pelvic peritoneum closure significantly reduces the incidence of postoperative perineal-related complications and shorten postoperative hospital stay.

This study was aimed to evaluate the frequencies and prognostic significance of the nucleophosmin 1 (NPM1) mutation, the fms-like tyrosine kinase 3 (FLT3) mutation and c-KIT mutation in acute myeloid leukemia (AML) and to explore their relevance to clinical characteristics, cytogenetics and survival. Genomic DNA from 78 newly diagnosed AML from August 2010 to October 2012 was screened by PCR and sequencing or capillary electrophoresis (CE) for NPM1, FLT3 and c-KIT mutations. The results showed that the incidence of NPM1 mutation was 14.1% in AML patients and 26.7% in normal karyotype AML patients. NPM1 mutant cases were significantly associated with old age (P < 0.05), high peripheral white cell count and platelet counts (P < 0.05) and low expression of CD34 (P < 0.05), but no statistic difference was found in sex, percentage of bone marrow blasts, Hb, expression of CD117 and HLA-DR, complete remission rate, overall survival and relapse rate (P > 0.05). The prevalences of FLT3-ITD and FLT3-TKD mutations were 11.5% (9/78) and 3.8% (3/78) respectively, and no one patient has both of the two mutations. Patients with FLT3-ITD mutation had higher white blood cell counts and percentage of in bone marrow blasts (P < 0.05), and lower overall survival (P < 0.05), more relative to normal karyotype (P < 0.05), while no statistic difference was found in sex, age, platelet count, Hb level, complete remission rate and relapse rate (P > 0.05). No statistic analysis was performed due to the cases of less FLT3-TKD mutation. C-KIT mutation accounts for 7.7% (6/78). Patients with C-KIT mutation had a higher percentage in abnormal karyotype (P < 0.05), and higher relapse rate (P < 0.05), and lower overall survival, whereas no statistic difference was found in sex, age, percentage of bone marrow blasts, peripheral blood cell count, complete remission rate (P > 0.05). It is concluded that the detection of NPM1, FLT3 and C-KIT mutations may contribute to guiding treatment and evaluating prognosis of patients with AML.
