Objective:Helicobacter pylori is one of the human pathogens causing gastric ulcers and cancers.A key virulence factor of H.pylori is the Cag pathogenicity island,which encodes a type IV secretion system.HP0525 is an essential component of the Cag system and acts as an inner membrane associated ATPase.To construct recombinant plasmid containing hp0525 gene of Helicobacter pylori(H.pylori)NCTC 11637,and analysis of sequence nucleic acid,express it in E.coli BL21 and study the influence of the HP0525 protein on proliferation of SGC-7901 cells.Methods:H.pylor hp0525 gene was amplified from the genome DNA by PCR,then operated T-A cloning and sequenced.The hp0525gene fragment was inserted directionally into vector pMD18-T to construct recombinant clones of hp0525 and was sequenced.The recombinant plasmid was transformed into E.coli BL21for expressing under induction of IPTG.Purify the expressed protein by Ni2+-NTA column chromatography.Expressed product was analyzed by Western blot and MALDI-TOF.Added the purified protein into SGC-7901 cells,the effect of cell proliferation in SGC-7901 cells induced by the recombinant protein was observed by MTT.Results:A 993 base pairs long hp0525 gene,which encodes a product of 330 amino acid,was obtained using PCR method and was cloned into pMD18-T vector successfully.The sequence analysis for hp0525 showed that it shares 97%~99% homology with other strains in Gene bank.SDS-PAGE showed a protein band with a relative molecular weight of 36 000,which was consistent with the expectation.The expressed product reached a purity of 97% after Ni2+-NTA column chromatography.The protein after dialyzed and annealed,was co-cultured with SGC-7901 cells,The protien of different concentration co-cultured with SGC-7901 cells for different times,found that the protein in low concentration stimulates proliferation of cells,to achieve some concentration,it inhibits proliferation of cells along with multiplication of the concentration of the protein;The protein inhibits proliferation of cells relay on the extension of time and concentration.Conclusion:It is indicated that the correct hp0525 gene was obtained and expressed in E.coli BL21.High purified protein was obtained by Ni2+-NTA column chromatography,the protein can inhibits proliferation of SGC-7901cells,and T-ATPase activity which posed a basis for further researching on its biological function.

Diabetes is a chronic noncommunicable disease,which is can't be cured,and only can be suppressed by long-term treatment and self-management.The clinical decision support system can simulate the thinking process of diabetes specialists in disease diagnosis,and can provide the regular medical treatment plans and recommend the optimal plans to doctors.Most of the existing clinical decision support systems are based on clinical guidelines,rule-based and case-based reasoning as well as ontology-based systems.The big data technology can acquire and process multiple heterogeneous data,and provide a more scientific personalized treatment plan.In recent years,a variety of big date processing methods have been applied to the clinical diagnosis of diabetes based on decision tree,neural network,fuzzy logic,support vector machine,APRIORI association rules and multidimensional analysis,and timing mining.However,these methods are still in preliminary stage.The framework of diabetes clinical decision support system based on big data technology was analyzed,and the future diagnostic and treatment methods were forecast.

Objective To study the effect of coenzymes complex combined with vitamin E on liver and kidney inju-ry induced by neonatal hyperbilirubinemia. Methods One hundred and fifty full-term neonatals with hyperbilirubinemia were chosen as observation groups, who were divided into mild, moderate and severe groups according bilirubin. Forty five healthy full-term newborns in the same period, who are either healthy or with physiological jaundice, were selected as con-trol group. Serum total bilirubin, gamma-glutamyl transferase (γ-GGT) , Malondialdehyde (MDA) and Cys-C were measured within 24 hours of hospital admission.The observation groups were randomly divided into regular and combined treatment groups. Coenzymes complex combined with vitamin E were given in addition to regular method to combined group while reg-ular group only received regular methods.All above biochemical indexes were tested in the 7th day after medication admin-istration. Results Serum MDA were higher in all observation groups (mild, moderate and severe groups) than in control group (P＜0.05);but the levels ofγ-GGT and Cys-C increased in moderate and severe groups compared with control group (P＜0.05). There were positive correlations (P＜0.05) between levels of serum total bilirubin with MDA,γ-GGT and Cys-C. Positive linear correlation were found between MDA with γ-GGT and Cys-C(P＜0.01). After early intervention,γ-GGT, Cys-C and MDA declined with drop of bilirubin level. This is more prominent and faster in a in combined treatment group than regular group (P＜0.05).Conclusion In hyperbilirubinemia newborns, lipid peroxidation activated by bilirubin may lead to damages of liver and kidney. Coenzymes combined with vitamin E have protective effect to these damages.

Results　From 2011 to 2021, the average annual registration rate of elderly patients with pulmonary tuberculosis in Xianning City, Hubei Province was 211.52/100 000 (5 289/2 500 496), which showed a downward trend （χ2 trend=58.06, P<0.05), and significantly higher than the average registration rate of 96.04/100 000 patients with pulmonary tuberculosis (26 463/27 554 195)(χ2=2 896.69, P<0.05). The average proportion of the registered number of elderly patients with pulmonary tuberculosis in the whole population was 19.99% (5 289/26 463), which showed an upward trend (χ2trend=272.05, P<0.05). The average positive rate of etiology in elderly patients with pulmonary tuberculosis was 51.86% (2 743/5 289), which was significantly higher than that in the whole population 46.41% (12 282/26 463) (χ2=52.53, P<0.05). The average proportion of retreated patients in elderly patients with pulmonary tuberculosis was 8.92% (472/5 289), which was significantly higher than that of retreated patients in the whole population 6.33% (1 674/26 463) (χ2=47.23, P<0.05). The sex ratio of male to female in elderly patients with pulmonary tuberculosis was 2.92∶1. Among the six counties (districts) under the jurisdiction of Xianning City, Hubei Province the registration rate of elderly tuberculosis patients in Xian'an district was the highest 262.20/100 000 (1 267/483 220), and that in Tongcheng County was the lowest 123.83/100 000 (575/464 338), with significant differences (χ2=233.67, P<0.05). Conclusion　The overall incidence of tuberculosis in the elderly in Xianning City , Hubei Province showed a downward trend, but the proportion of the incidence of tuberculosis in the elderly in the whole population has increased year by year, suggesting that the elderly are the key population of tuberculosis prevention and control in Xianning City in the future, and comprehensive prevention and control measures should be taken to reduce the incidence of tuberculosis in the elderly population.

Objective To investigate the influence of heparin pretreatment on serum and lung tissue level of neutrophil extracellular traps (NETs) in septic mice model and its molecular mechanism.Methods Ninety male C57BL/6J mice were randomly divided into control group (n = 30), lipopolysaccharides (LPS) group (n = 30, 30 mg/kg LPS in 100μL normal saline was intraperitoneally injected) and LPS+heparin group (n = 30, 8 U of heparin in 20μL normal saline was subcutaneously injected 30 minutes before the injection of LPS). Six hours later of LPS injection, blood was collected and lung tissue was harvested. Enzyme linked immunosorbent assay (ELISA) was used to assess the concentration of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and histones 2AX (H2AX), neutrophil elastase (NE), which reflected NETs concentration. PicoGreen fluorescent dyes was used to detect serum circulating free DNA (cf-DNA/NETs) concentration. The protein expression levels of H2AX and NE in lung tissue were examined by Western Blot.Results The serum concentrations of TNF-α, IL-6, H2AX, NE, cf-DNA/NETs, and the protein expression levels of H2AX and NE in lung tissue of septic mice were significantly higher than those of control group [TNF-α (ng/L): 133.0±14.1 vs. 2.7±1.0, IL-6 (ng/L): 3911.2±189.2 vs. 298.9±52.5, H2AX (ng/L): 545.5±40.0 vs. 21.9±8.3, NE (μg/L): 6.48±0.12 vs. 0.47±0.15, cf-DNA/NETs (μg/L): 846.3±137.5 vs. 152.7±36.4, H2AX protein (gray value): 1.14±0.09 vs. 0.68±0.04, NE protein (gray value): 0.56±0.03 vs. 0.32±0.04, allP < 0.05]. After heparin pretreatment, levels of serum TNF-α, H2AX, NE, cf-DNA/NETs, and protein expression levels of H2AX and NE in lung tissue were significantly reduced [TNF-α (ng/L): 83.2±7.6 vs. 133.0±14.1, H2AX (ng/L): 435.0±39.0 vs. 545.5±40.0, NE (μg/L): 4.26±0.17 vs. 6.48±0.12, cf-DNA/NETs (μg/L): 606.5±73.9 vs. 846.3±137.5, H2AX protein (gray value): 0.91±0.03 vs. 1.14±0.09, NE protein (gray value): 0.42±0.03 vs. 0.56±0.03, allP < 0.05], but no significant change was found in IL-6 (ng/L: 3919.9±166.6 vs. 3911.2±189.2,P > 0.05).Conclusion Heparin pretreatment could significantly decrease the level of NETs in serum and lung tissue, and can be the potential mechanism of its organ protection in sepsis.

OBJECTIVE To observe the regulation effect of chidamide on energy metabolism in HCT-8 and HT-29 cells. METHODS HCT-8 and HT-29 cells were treated with chidamide 5,10 and 20 μmol · L-1. Morphological changes of these cells were observed under an ordinary optical microscope. Cell proliferation was detected by MTT. ATP production was determined by CellTiter-Glo? assay kit. Metabolic changes were tested by glycolytic stress kit. The mRNA level of lactate dehydrogenase A (LDH-A)was analyzed by real-time quantitative PCR,whereas the protein level of LDH-A was analyzed by Western blotting. RESULTS Compared with control group,cell morphology of HCT-8 and HT-29 cells in chidamide treated group was irregular,accompanied by deformation,shrinkage and cell debris, and the inhibitory rate of proliferation increased(P<0.05). There was no significant difference in ATP total content between chidamide 5 and 10 μmol · L-1 16 h treatment groups,but in chidamide 20 μmol · L-1 treatment group it was decreased(P<0.05). Chidamide 20μmol · L-1 had no effect on oxygen consumption rate, but glycolysis ATP generation rate was reduced by 30.7% and 37.9%(P<0.05),respectively. Chidamide 20μmol · L-1 had no effect on LDH-A mRNA level,but it decreased the protein level of LDH-A(P<0.01). CONCLUSION Chidamide can abate the respiratory metabolic ability of HCT-8 and HT-29 cells. The mechanism may be related to the down-regulation of LDH-A.
