Objective:To survey the effect of the Dureping Injection on the kinetic change of nitrous oxide(NO) in macrophage infected by the influenza virus FM1 strain.Methods:The murinal celiac macrophage(Ana-1) was infected by the virus,add the different concentration of the drug in the supernatant of the macrophage for 6 h,12 h,24 h and 36 h.The level of the NO in the supernatant was measured by the method of traditional Griess.Ana-1 cell line was infected by influenza virus FM1 strain,then treated with Dureping Injection 1 ?g/ml for 24 h.The cells were then collected,mRNA was extracted and the expression of NF-?B p65 was measured by RT-PCR;The nuclear protein was extracted and the expression of NF-?B p65 measured by Western blot.Results:60 ?g/ml,30 ?g/ml,10 ?g/ml and 1 ?g/ml group of Dureping Injection down-regulated amount of NO secreted by the Ana-1 cells infected by virus,and it was showed in dose relationship significantly;1 ?g/ml group of Dureping Injection down-regulated the expression of the NF-?B p65 mRNA and protein.Conclusion:Dureping Injection has an obvious effect against influenza virus FM1 strain by depressing the activity of NF-?B,which prevents the production of NO secreted by Ana-1 cells infected by the virus.

Objective: To probe into the relation of nutritional status with serum lipids levels in children. Methods: The levels of serum lipids, dietary intakes and physical indices were investigated for 316 children aged 7～11 years in Beijing Chao Yang District. Results: 36.21% of energy was from fat. Of 60.1% children the daily intakes of cholesterol were equal to or more than 300 mg. The intakes of cholesterol were positively associated with TC and apoB levels. Energy percentage from carbohydrate was also positively related with HDL C level. On the other hand, the levels of TC, HDL C and apoAI in cholesterol high intake group were more than control group. The TC, TG, LDL C, apoB and Lp(a) levels in overweight/obese children were more than normal and underweight children, and the lipids levels increased with overweight degree. In boys the waist hip ratios were positively associated with TC, TG, LDL C and apoB levels, negatively with HDL C level. Conclusion: Overweight/obesity (especially abdominal obesity) and unreasonable diet were related closely with dyslipidemia in children. It could be used in early diagnosis for high risk children of dyslipidemia.

Taking Duke University as an example, this article makes a comparison between the major of biomedical engineering in the Southeast University and that in American universities in term of subject direction, faculty, teaching principle and status of publishing academic papers. Through the comparison and analysis, the problems we face were explored. From the comparison and summary the future improvements in four aspects, such as strengthening the interdisciplinary among different majors, etc. so as to provide an inspiration on the future perspectives of research and teaching in biomedical engineering in China.

OBJECTIVETo investigate the influence of Dureping injection to the murinal celiac macrophage Ana-1 on TIR signal pathway.

METHODAna-1 cell line was infected by influenza virus FM1 strain and treated with the Dureping injection in different concentrations (10.1 mg x L(-1) group) for 12 h and 24 h. Then we collected the cells, extracted mRNA and measured the expressions of TLR7, MyD88, IRAK4, TRAF6 and NF-kappaB p65 respectively by RT-PCR.

RESULTDureping injection down-regulated the expression of TLR7, MyD88, IRAK4, TRAF6 and NF-kappaB p65 mRNA in Ana-1 cell line infected by influenza virus, in a dose-dependent manner significantly.

CONCLUSIONDureping injection has an obvious effect against influenza virus FM1 strain by regulating the TIR signal pathway.

Objective To study the distribution characteristics of peripheral blood stem cell-like memory T cells ( TSCM) in patients with gastric cancer and to analyze their relationship to clinicopathologi-cal characteristics and clinical application value. Methods Thirty-two patients hospitalized with gastric cancer in our hospital from July to December, 2018 were selected as the case group. Twenty-three healthy volunteers recruited during the same period served as the control group. The percentages of TSCM, naive T cells ( TN) and memory T cells ( TM) were detected by flow cytometry and the differences between the two groups were compared. The relationship of clinicopathological features to TN, TSCM, TSCM/TN ratio and TM was analyzed. Results The percentages of TN and TSCM in peripheral blood of the patients were signif-icantly lower than those of the healthy control group, while the ratio of TSCM to TN was significantly in-creased in the case group (all P<0. 05). The proportion of TN was negatively correlated with tumor TNM stage and invasion depth, and positively correlated with the degree of tissue differentiation. The ratio of TSCM to TN was positively correlated with TNM stage, invasion depth and lymph node metastasis. Conclu-sions TN and the ratio of TSCM to TN in peripheral blood of patients with gastric cancer are closely related to clinical and pathological characteristics such as tumor stage and invasion depth, which could be used as a new way to evaluate the immune status of patients. TSCM might have important clinical application value in adoptive cellular immunotherapy of gastric cancer, but large-scale multi-center clinical studies are needed for further evaluation.

Objective: To evaluate Chinese clinical practice guideline/consensus for digestive diseases published in the past five years in order to recommend the high-quality guidelines and help with the promotion and implementation of them. Methods: From January 2013 to June 2018, the officially published Chinese practice guideline/consensus for digestive diseases were selected. The inclusion and exclusion criteria of the guideline/consensus was evaluated by "Evaluation Criteria for Chinese Clinical Practice Guidelines 2017(AGREE-China 2017)" . The guideline/consensus were independently scored by three evaluators and then calculated the average value. Descriptive analysis methods were used to analyze the Chinese clinical practice guideline/consensus for digestive diseases. Those with the total score more than 40.0 points were included in the recommended list. Results: A total of 119 officially published clinical practice guideline/consensus of digestive diseases were retrieved, and 74 clinical practice guideline/consensus for digestive diseases were included in the evaluation. Among them, 18 (24.3%, 18/74) scored over 60.0 points, 31 (41.9%, 31/74) scored between 40.0 and 59.9 points. Finally 48 guideline or consesus were selected for the recommended list 19 cases of esophagus and gastrointestinal diseases, 18 cases of liver diseases, five cases of biliary and pancreafic diseases, and six cases of digestive endoscopy. The three guideline/consensus with the high scores (> 80.0 points) were The Fifth Chinese National Consensus Report on the Maragement of Helicobacter pylori Infection, Consensus on the Diagnosis and Treatmeat of Cholestatic Liver Disease (2015) and Guidelines for the Prevention and Treatment of Chroaic Hepatitis B (2015 Update). The higher the score of the guideline/consensus, the more scientific and rigorous the method, and the clearer the evaluation of evidence grade and the description of the formation of recommendations. Compared with international standards of guideline/consensus development, there are still some problems in Chinese guidelines or consensus such as no explanation of retrieval strategy, no basis of evidence classification and no description of the formation process from evidence to recommendation. Conclusions The quality of Chinese clinical practice guideline/consensus for digestive diseases has been improved year by year. However the scientific aspects need to be further improved. AGREE-China which demonstrates good validity, realiability and practicability is easy and clear to use.
