Objective:To explore the effect of exercise on glycemic control and physical indicators among community-dwelling persons with type 2 diabetes mellitus (T2DM).Methods:A total of 42 T2DM patients undergoing regular follow-up at a community health center were divided into a control group and an exercise group. To minimize confounding factors, 1∶1 propensity score matching was performed, resulting in 21 patients in each group. Both groups received standardized diabetes management, including medication, dietary guidance and diabetes health education. The exercise group additionally performed exercises which integrated sports and medical care models. The experiment lasted 8 weeks. Before and after the intervention, glycosylated hemoglobin A1c (HbA1c) levels, body weight, body mass index (BMI), fat mass, visceral fat area (VFA), fat mass index (FMI) and appendicular skeletal muscle mass index (ASMI) were recorded and compared between the two groups. Moreover, the actual exercise compliance of the exercise group was observed, along with any adverse events such as hypoglycemia or exercise-related injuries, as well as changes in antidiabetic medication dosage.Results:After the intervention, significant improvement was observed in both groups in all of the measurements, but with the average HbA1c, BMI, fat mass, VFA and FMI values of the exercise group then significantly better than the control group′s averages. The average compliance rate in the exercise group was 60%. No cases of hypoglycemia or exercise-related injuries were reported during the intervention, and there were no changes in the use of anti-diabetes medications.Conclusions:Exercise effectively improves glycemic control and physical indicators among community-dwelling T2DM patients. However, exercise compliance needs improving.

Insulin-like peptides(ILPs)play a crucial role in the biological processes of nematode metabolism,signal transduction,and developmental processes,representing potential therapeutic targets for nematode infections in animals.In order to explore the specific role of ILPs in nematode development and infection,genome-wide identification,sequence and evolution analysis of the ILPs coding genes were conducted on Haemonchus contortus(H.contortus);transcriptional levels of these ILPs coding genes among developmental stages were determined by a real-time quantitative PCR method;recombinant ILPs were produced in prokaryotic system for polyclonal antibody prep-aration and Western blot analysis;indirect immunofluorescence localization experiment was used to reveal the tissue distribution of ILPs at different developmental stages.It was showed that the number of ILPs coding genes in H.contortus were significantly reduced compared with that of Caenorhabditis elegans,namely three members of ILPs coding genes exhibiting antagonistic fea-tures;the highest transcriptional levels of ILPs coding genes was detected in the infective third stage larvae of H.contortus;ILPs were found dominant in the intestine and hypodermis of the in-fective larvae of this parasitic nematode.In this study,three genes encoding antagonistic ILPs were identified in H.contortus,they might play a role in regulating the development and infection processes.The finding lay a foundation for the study of nematode hypobiosis(larval diapause)in animals and the screening of potential intervention targets.

Objective To explore the role and potential mechanisms of all-trans retinoic acid(ATRA)on activation and oxidative stress of hepatic stellate cell(HSC).Methods Platelet-derived growth factor(PDGF-bb,10 ng/ml)was applied to induce the activation of HSCs,which was then treated with ATRA at a dosage of 5 μmol/L for 48 h.The effects of ATRA on HSC activation were evaluated by detecting changes in cell growth viability and phenotypic marker expression.The effects of ATRA on HSC oxidative stress were evaluated by detecting changes in intracellular reactive oxygen species(ROS),reduced glutathione(GSH)and malondialdehyde(MDA),and the expression of antioxidant genes.The effects of ATRA on HSC autophagic activity were evaluated by detecting changes in autophagy marker expression and autophagic flow.Results Compared with the PDGF-bb group,the cell viability was significantly reduced in ATRA-treated HSCs(P＜0.01),as well as the expression of α-SMA and Collagen I.The intracellular levels of ROS and MDA were significantly reduced in ATRA-treated HSCs(P＜0.01),whereas the GSH level was significantly increased(P＜0.01).The expression levels of antioxidant genes(NRF2,HO-1,and ATF4),were significantly higher in ATRA-treated HSCs than those in the normal ones under PDGF-bb condition(P＜0.01).Meanwhile,the expression of autophagy markers Beclin 1 and LC3 Ⅱ/I,and signal of autophagy flow in ATRA-treated HSCs were found to be significantly reduced(P＜0.01).Conclusion ATRA significantly inhibited PDGF-bb-induced HSC activation and reduced the level of oxidative stress and autophagic activity of HSCs,which had potential applications in the prevention and treatment of liver fibrosis.

OBJECTIVE: To study the expression of Cyclin D1 in nasopharyngeal carcinoma cells processed by epigallocatechin gallate(EGCG) and it's significance, and revealed the anti-tumor mechanism of EGCG against nasopharyngeal carcinoma. METHOD: CNE-2 cells were treated by EGCG at different concentrations, the morphological changes of CNE-2 cells were observed by inverted microscope; the inhibition ratio of cell proliferation was detected by MTT colorimetric method, flow cytometry was used to analyze the changes of cell cycle. The expression of Cyclin D1 mRNA was detected by RT-PCR. RESULT: After treated by EGCG, the CNE2 cells decreased in amount and density, some of which became roll and small; Floating and dead cells can be seen in the inverted microscopy; cell proliferation was significantly inhibited in a time and dose dependent (P < 0.05). CNE-2 cells were arrested at G1/G0 phase. The expression of Cyclin D1 mRNA was down-regulated by EGCG with concentration and action time dependent (P < 0.05). CONCLUSION EGCG resisted nasopharyngeal carcinoma by inhibiting the cell proliferation, The down regulation of Cyclin D1 mRNA expression in a time and dose dependent may be the possible mechanisms.

OBJECTIVE:To probe into the general regularity and characteristics of ADR in our hospital. METHODS:117 ADR reports were analyzed retrospectively in respect of the patient’s gender,age,dosage form,route of medication,medication combination,category of drugs,involved organs and system and clinical manifestation,ect. RESULTS:Of total 117 cases of ADR,female cases of 69 accounted for 58.97% while 48 male cases 41.03%. ADR cases were mainly found in the group aged from 41 to 50(23.93%). ADR was predominantly caused by intravenous drip infusion(86.32%). 46 kinds of drugs in 10 categories were involved,in which antimicrobial drug took dominate place including 20 kinds in 10 categories(58.97%). The most common clinical symptom represented as lesion of skin and its appendants(54.70%). 117 cases were cured and improved without death case. CONCLUSION:Great importance should be attached to rational use of drug and safety of drug use of special population.
