Escherichia coli AFP111 is a spontaneous mutant with mutations in the glucose specific phosphotransferase system (ptsG) in NZN111 (delta pflAB deltaldhA). In AFP111, conversion of xylose to succinic acid generates 1.67 molecule of ATP per xylose. However, the strain needs 2.67 molecule ATP for xylose metabolism. Therefore, AFP111 cannot use xylose due to insufficient ATP under anaerobic condition. Through an atmospheric and room temperature plasma (ARTP) jet, we got a mutant strain named DC111 that could use xylose under anaerobic condition in M9 medium to produce succinic acid. After 72 h, DC111 consumed 10.52 g/L xylose to produce 6.46 g/L succinic acid, and the yield was 0.78 mol/mol. Furthermore, the reaction catalyzed by the ATP-generating PEP-carboxykinase (PCK) was enhanced. The specific activity of PCK was 19.33-fold higher in DC111 than that in AFP111, which made the strain have enough ATP to converse xylose to succinic acid.

Escherichia coli BA002, in which the ldhA and pflB genes are deleted, cannot utilize glucose anaerobically due to the inability to regenerate NAD+. To restore glucose utilization, overexpression of nicotinic acid phosphoribosyltransferase (NAPRTase) encoded by the pncB gene, a rate-limiting enzyme of NAD(H) synthesis pathway, resulted in a significant increase in cell mass and succinate production under anaerobic conditions. However, a high concentration of pyruvate was accumulated. Thus, co-expression of NAPRTase and the heterologous pyruvate carboxylase (PYC) of Lactococcus lactis subsp. cremoris NZ9000 in recombinant E. coli BA016 was investigated. Results in 3 L fermentor showed that OD600 is 4.64 and BA016 consumed 35.00 g/L glucose and produced 25.09 g/L succinate after 112 h under anaerobic conditions. Overexpression of pncB and pyc in BA016, the accumulation of pyruvic acid was further decreased, and the formation of succinic acid was further increased.

Objective:To explore the role of lectin-like oxidized low density lipoprotein (ox-LDL) receptor(LOX1) in ox-LDL stimulating endothelial nitric oxide(NO) production. Methods: LOX1 mRNA expression was detected by reverse transcription-polymerase chain reaction(RT-PCR). The quantity of NO was detected by Enzyme-method. Results: Incubation of ox-LDL increased endothelial NO production and LOX1 mRNA expression. When HUVECs were incubated with ox-LDL as well as the inhibitor of LOX1, polyinosinic acid,the increase of NO production and LOX1mRNA expression were attenuated. Conclusion: Ox-LDL enhanced endothelial NO production in a concentration-dependent manner, and the effect of ox-LDL on endothelial NO was mediated by LOX1.

OBJECTIVE： To summarize the problems and countermeasures which the construction of drug clinical trial institutions face after China Food and Drug Administration （CFDA） join in ICH， and its effects on clinical study management in China. METHODS： Combined with the experience on Good Clinical Practice （GCP） in our hospital during recent years， reviewing related content of ICH-GCP， the differences between China’s GCP （CFDA-GCP） and ICH-GCP， the problems faced by drug clinical trial institutions after joining in ICH， and the thinking of China’s clinical research were discussed. RESULTS & CONCLUSIONS： There were differences between CFDA-GCP and ICH-GCP in the management concept of clinical drug trials， the structure and function of ethical committees， the protection of the rights and interests of subjects， the choice of researchers and research institutions， management requirements of experimental drugs and the management of documents and data. After joining in ICH， the current organization and management structure， system and standard operating procedures， ethics committee， GCP training and continuing education， professional quality control system， experimental drug management， data management and information system construction and upgrading， clinical research coordinator management and other aspects of the drug clinical trial institutions were far from the requirements of ICH. The standardization of drug clinical trial institutions in China can be further promoted by revising regulations and guidelines， formulating standard operating procedures in line with ICH-GCP， building standardized ethics committees， implementing GCP training and continuing education， improving quality control system and drug management in clinical trials， strengthening hardware and software construction and clinical coordinator management， etc. At the same time， problems such as fewer full-time personnel and weak implementation of the system can be improved by strengthening project management， improving the quality of employees and building normal cross-regional cooperation.

Objective:To compare the short-term clinical efficacy, adverse reactions and pharmacoeconomics of advanced mutation negative lung adenocarcinoma treated by albumin-bound paclitaxel or pemetrexed combined with cisplatin.Methods:From September 2019 to October 2020, 80 patients with advanced lung adenocarcinoma diagnosed in the First Affiliated Hospital of Bengbu Medical College were divided into observation group and the control group according to the randomized digital table, with 40 cases in each group. The observation group received albumin-bound paclitaxel combined with cisplatin, and the control group received pemetrexed combined with cisplatin. After 2 cycles of treatment, the short-term efficacy and the adverse reactions of the two groups were evaluated. The cost of chemotherapy drugs and the average length of hospital stay were compared between the two groups.Results:The objective response rates of the observation group and the control group were 30.0% (12/40) and 32.5% (13/40), the disease control rates were 77.5% (31/40) and 82.5% (33/40) respectively, and there were no significant differences ( χ2=0.058, P=0.809; χ2=0.313, P=0.576). The adverse reactions of the two groups were mainly grade Ⅰ-Ⅱ. The incidences of leucopenia, neutropenia, thrombocytopenia, hemoglobin decreased, gastrointestinal reaction, liver function damage and renal function damage in the observation group were 20.0% (8/40), 20.0% (8/40), 20.0% (8/40), 17.5% (7/40), 37.5% (15/40), 12.5% (5/40) and 7.5% (3/40) respectively, those in the control group were 25.0% (10/40), 20.0% (8/40), 17.5% (7/40), 15.0% (6/40), 32.5% (13/40), 17.5% (7/40) and 5.0% (2/40) respectively, and there were no statistically significant differences between the two groups ( χ2=0.287, P=0.592; χ2<0.001, P>0.999; χ2=0.082, P=0.775; χ2=0.092, P=0.762; χ2=0.220, P=0.639; χ2=0.392, P=0.531; χ2<0.001, P>0.999). The median cost of chemotherapy drugs and the median length of hospital stay in the observation group were 7 453 yuan and 6 days respectively, which were less than 8 956 yuan and 7 days in the control group, with statistically significant differences ( Z=-3.057, P=0.002; Z=-2.733, P=0.006). Conclusion:The short-term efficacy of albumin-bound paclitaxel combined with cisplatin is equal to pemetrexed combined with cisplatin in treatment of advanced mutation negative lung adenocarcinoma, and the adverse reactions are similar. However, the average cost of chemotherapy drugs of albumin-bound paclitaxel combined with cisplatin is less than pemetrexed combined with cisplatin, and the average length of hospital stay is shorter.
