Objective To explore the impact of overweight and obesity on flow mediated dilation (FMD) in adult people.Methods Intact clinical data of 183 healthy people, aged 30~65 in our hosipital were analyzed.According to BMI, all people were divided into obesity group (48 cases), overweight group(75 cases) and normal group (60 cases).FMD was detected by E tracing of ultrasonic.Weight, WC, BFP, baPWV, BP,FPG,CHO,HDL-C,LDL-C,TG and UC were observed at the same time.FMD of three groups were compared and the risk factors of FMD were analyzed.Results The level of FMD in the obesity group and overweight group was significantly higher than that in the normal group[(5.63±2.76)%,(6.45±2.54)% vs.(8.31±3.04)%](F=13.77,P<0.001);there was no statistically significant difference between the obesity group and overweight group (t=1.68,P>0.05).Age(β=0.078,95%CI: 1.004,1.164),BMI(β=0.465,95%CI 1.148,2.208),LDL-C(β=2.294,95%CI: 9.918,1.612) and UC(β=0.007,95%CI 0.986,1.000) were independent risk factors of decreased FMD(P<0.05).Conclusion Age, BMI, LDL-C and UC are independent risk factors of decreased FMD.

Strong inhibition of Bacillus subtilis strain NJ-18 on mycelia growth of Alternaria solani was observed in the antagonistic tests by cylinder plate methods, and the inhibition width was 21.5 mm. Observation under microscope found that the supernatant of fermentation from NJ-18 could make the pathogen hyphae cells malformed and swelled, and consequently the growth of the pathogen was inhibited. Determining of the colonization in potato plants by the signed rifampicin-resistance in NJ-18 showed that it could colonize well in the plants, the colonization quantity of NJ-18 in the root and stem of the potato detected 30 days after fermentation irrigation was 103 CFU/g plant’s fresh weight. In pot experiment, we inoculated the tomato plants with the spore suspensions of Alternaria solani after spraying the fermentation of NJ-18, the results were investigated in 14 days and the efficacy in controlling the disease was 72.9%, which was significantly higher than 45.7%, the efficacy resulted from spray treatment of 2000 fold dilution of 50% iprodione wetable powder.

Objective To investigate the anti-inflammatory activity of the main active ingredients in the dried stem bark of Daphne giraldii Nitsche.Methods Severialchemical compounds like vladinol D, pinoresinol, daphneticin, daphnoretin, daphnetin, giraloid A and giraldoid B were isolated from the stem barks. The CCK-8 experiemnts were analyzed for the cytotoxicity study. The cells were divided into the control group, the model group and the treatment group according to random number table method. The control group and the model group were added with 50μl culture medium. Moreover, treatment group was added with different concentrations (50.00, 25.00, 12.50, 6.25, 3.12μg/ml) of the solutions of giraloid A, giraldoid B and daphneticin. Then, RAW264.7 cells were treated with 50μl LPS (4μg/ml) for 24 h in the model group and treatment group. Griess reagent was used to determine the amount of NO release, and the secretion of TNF-α was detected by ELISA kit.Results Cytotoxicity test indicated that giraldoid A (50.00μg/ml), giraldoid B (50.00μg/ml) and daphneticin (50.00μg/ml) showed noobvious cytotoxicity. Giraldoid B (12.50, 25.00, 50.00μg/ml) could inhibit the production of NO (271.86% ± 20.92%, 256.48% ± 20.92%, 199.31% ± 15.16%vs.358.62% ± 28.64%) and  TNF-α (647.87% ±115.79%, 618.42% ± 87.52%, 588.33% ± 87.94%vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group. Giraldoid A (25, 50μg/ml) could inhibit the production of NO (234.99% ± 34.28%, 167.36% ± 25.76% vs.358.62%±28.64%) and TNF-α (691.76% ± 60.37%, 534.01% ± 41.60% vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group. Daphneticin (12.5, 25, 50μg/ml) could inhibit the production of NO (283.89% ± 36.69%, 243.08% ± 48.19%, 225.92% ± 33.67% vs.358.62% ± 28.64%) and TNF-α (713.77% ± 121.96%, 670.62% ± 18.70% vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group.Conclusions Giraldoid A, giraldoid B and daphneticin exhi bited anti-inflammatory effect through inhibiting the release of NO and the production of TNF-α in RAW264.7 induced by LPS.

Ebola virus (EBOV) and Marburg virus (MARV) belong to the family Filoviridae. Filoviruses cause severe filovirus hemorrhagic fever (FHF) in humans, with high case fatality rates, and represent potential agents for bioterrorism and biological weapons. It is necessary to keep surveillance of filoviruses, even though there is no report of their isolation and patients in China so far. To characterize MARV morphology, the Lake Victoria marburgvirus--Leiden was stained negatively and observed under a transmission electron microscope which is one of important detection methods for filoviruses in emergencies and bioterrorism. MARV showed pleomorphism, with filamentous, rod-shaped, cobra-like, spherical, and branch-shaped particles of uniform diameter but different lengths. Pleomorphism of negatively stained MARV is summarized in this article, so as to provide useful information for possible electron microscopic identification of filoviruses in China.

Objective:To explore the expression of TNF a and IL-10 in different layers of laryngeal tissues after laryngeal transplantation and its relationship with acute rejection.Methods:Laryngeal heterotopic transplantation was performed in Wistar and SD rats(Wistar→SD rats).The SD rats were divided into 4 groups:GroupⅠ:Sham control(receive no transplantation): GroupⅡ(receive transplantation,without cyelosporine A treatment);GroupⅢ(receive transplantation.with 5 mg?kg~(-1)?d cyelosporine A treatment):and GroupⅣ(receive transplantation.with 10 mg?kg~(-1)?d~(-1)cyelosporine A treatment).The transplanted larynx was harvested on 3,7 and 11 days after transplantation for pathological examination.The expression of TNF-?and IL-10 in different layers of grafts was detected immunohistochemically.Results:Pathological observation showed mild,moderate and severe acute rejection in GroupⅡandⅢon 3.7 and 11 days after transplantation,respectively:there was no obvious rejection in GroupⅣ.Immunohistochemical staining showed expression of TNF-?and IL-10 in GroupⅡ.Ⅲ.andⅣ,not in GroupⅠ.The ratios of the positive areas of TNF-?and IL-10 in the mucosal and submucosal layers were significantly higher than those in the muscle and cartilage layers of laryngeal tissues(P

ObjectiveTo apply the Schwann cell neurilemma channel(SCNC) in promoting the regeneration of injuried spinal cord.MethodsSpinal cords of rats after laminectomy at T8/9 were divided in 3 groups randomly: 10 rats were transplanted with SCNC(Group A);10 rats only made models(Group B);10 rats were as normal control group(Group C).All rats received behaviour survey and inclined plane test every week 8 weeks after operation.6 weeks after operation,they were measured with cortical somatosensory evoked potential(CSEP).And 8 weeks after operation,all specimens were studied histologically.ResultsCSEP could be recorded in group A and C,but not in group B.There were marked differenties between group A or C and group B in behavior survey,inclined plane test.Amount of nerve fibers regenerated through the injury gap in group A was significantly larger than that in group B.ConclusionSCNC could facilitate axonal regeneration and promote the repairing of injuried spinal cord.

Objective To analyze the situation of smoking control calls at 12345 citizens′ hotline in Shanghai and investigate the smoking control hotspots concerned by citizens, the handling efficiency and quality of the hotline management, especially after the tobacco control ordinance was amended. Methods Statistical analysis was made on 48 945 smoking control calls, and data model established by natural language processing. Results After amendment of the tobacco control ordinance, there was a great increase in the number of smoking control calls, which reached a peak in 2017, and became 6.7 times that of 2016.Complaint report was the most important part of tobacco control calls, accounting for 76.24% of the total.Work and dining places were the main venue for complaints, while restaurants and offices were with the largest number of calls.The proportion of health departments in all responsible departments was the largest, accounting for 29.71%.Criticism and education were still the main way to deal with the problem, which was far from meeting the demands of citizens in this regard. Conclusion Publicity can mobilize the enthusiasm of the citizens to participate in tobacco control.The working efficiency and quality of responsible departments still needs to be improved.Citizen′s appeal can serve as a reference for future amendments to the law.

A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.
