Objective To evaluate the association of apM1 gene single nucleotide polymorphisms (SNP) with type 2 diabetes mellitus in Chinese population. Methods Odds ratios (OR) of apM1 gene SNP distribution were analyzed. The Meta-analysis software (RevMan 4.3.1) was employed for summarizing the studies,calculating the pooled OR and its 95% CI and testing the overall effects. Egger's test and fail-safe number for P=0.05 (Nfs<,0.05>) were performed for evaluating the publication bias. The sensitivity analysis by different effect models and sample sizes were employed for the reliability of Meta-analysis. Results Nine literatures were obtained, apM1 gene SNP45 showed remarkable heterogeneity among the studies (P<0.10). Sub-group analysis revealed that the discrepancy based on southern Chinese individuals was the main source of the total heterogeneity.The distribution frequencies of apM1 gene SNP45G, SNP45GG, SNP276G and SNP276GG were significantly higher in Chinese type 2 diabetes mellitus group than those in NGT group (P<0.05). Their pooled OR and 95% C/were 1.50[1.12,2.02], 2.15[1.53, 3.02],1.23[1.03, 1.46] and 1.26[1.00,1.59], respectively (all P<0.05). The distribution of apM1 gene SNP45TG and SNP276GT between type 2 diabetes mellitus and normal glucose tolerance group revealed no difference among these studies. The results of publication bias diagnostics and sensitivity analysis accounted for the reliability and stability of this Meta-analysis. Conclusion apM1 gene SNPs are strongly associated with type 2 diabetes mellitus in Chinese population. SNP45G and SNP276G seem to be risk factors for type 2 diabetes mellitus.

Objective To investigate the effects of liraglutide on gene expression related to cholesterol metabolism in ApoE-/-mice with adiponectin deficiency. Methods Thirty six ApoE-/-mice fed with the high-fat diet were subdivided into four groups. One group was given 100 μl(1×109PFU) of adenoviral pAd-U6-GFP(GFP group, n=6). The second group received 100 μl of adenoviral pAd-U6-Acrp30(ADI group, n=10). The third group was given 100 μl of adenoviral pAd-U6-Acrp30 and liraglutide(HEA group, n=10) and the fourth group was given only 100 μl sterile saline(HF group, n=10). Insulin sensitivity and glucose metabolism were assessed by the hyperinsulinemic-euglycemic clamp technique using 3-[3H] glucose as a tracer. Plasma adiponectin level was evaluated using a commercially available ELISA kit. The mRNA expressions of genes involved in cholesterol metabolism were measured by quantitative realtime PCR. Results Fasting blood glucose(FBG), free fatty acids(FFA), total cholesterol, triglyceride, low density lipoprotein cholesterol, adiponectin, and fasting plasma insulin(FINS) in ADI mice were significantly higher than those in the other groups(P<0.01), while high density lipoprotein cholesterol was significantly lower(P<0.05). During the clamp, glucose infusion rate(GIR) in ADI group was significantly lower than the other groups(P<0.01), and hepatic glucose production(HGP) significantly higher in ADI group(P<0.01). The mRNA expressions of INSIG2 and LDLR in ADI group were significantly down-regulated in HEA group(P<0.01 or P<0.05), while HMGCR and SREBP-2 were significantly up-regulated in HEA group(P<0.01 or P<0.05). Conclusions Liraglutide regulates a number of genes involved in cholesterol metabolism and ameliorates hypercholesterolemia by elevating plasma adiponectin level.

OBJECTIVETo investigate the effects of Qili Qiangxin capsules on the amino-terminal pro-brain natriuretic peptide (NT-proBNP) level and cardiac function in patients with silicosis.
METHODSHospitalized silicosis patients with heart failure were divided into treatment group (41 cases) and control group (30 cases) according to their own will. Both groups received comprehensive symptomatic treatment; in addition, the treatment group received Qili Qiangxin capsules. The treatment lasted 6 months. The observed items included NT-proBNP level, 6-minute walk test, ultrasonic cardiogram, and NYHA classification before and after treatment.
RESULTSAccording to NYHA classification, the response rate was 29.27%in the treatment group and 10.00%in the control group; there was a significant difference between the two groups (P < 0.05). The average walk distance in the treatment group was increased from 150.96±73.12 m before treatment to 169.32±77.04 m after treatment, and the improvement was statistically significant (P < 0.05). The average NT-proBNP level in the treatment group was reduced from 1154.44 ± 480.79 ng/L before treatment to 494.49 ± 342.61 ng/L after treatment, and the reduction was statistically significant (P < 0.01). Left ventricular ejection fraction was significantly improved in the treatment group (P < 0.05).
CONCLUSIONQili Qiangxin capsules in addition to comprehensive symptomatic treatment can significantly reduce NT-proBNP level and improve cardiac function in silicosis patients, and thereby improve patients' quality of life.

Objective:To explore the feasibility of estimating adenoma detection rate (ADR) based on polyp detection rate (PDR) in colonscopy.Methods:In the present single-center retrospective study, the conversion coefficient was calculated based on the total colonoscopy cases in 2017. ADR of each colonoscopists was estimated based on PDR and conversion coefficient, which was then verified compared with the actual ADR for consistency.Results:A total of 25 112 colonoscopies with 20 experienced colonoscopists were included. The overall conversion coefficient was 0.483. The intraclass correlation coefficient of the actual ADR and the estimated ADR was 0.818 (95% CI: 0.596-0.924, P<0.01). Conclusion:It is feasible to estimate ADR based on PDR, but this method is only an expediency. More attention should be paid to the establishment of a standardized electronic database.

The objective was to investigate the effect of kinsenoside (Kin) treatments on macrophage polarity and evaluate the resulting protection of chondrocytes to attenuate osteoarthritis (OA) progression. RAW264.7 macrophages were polarized to M1/M2 subtypes then administered with different concentrations of Kin. The polarization transitions were evaluated with quantitative real-time polymerase chain reaction (qRT-PCR), confocal observation and flow cytometry analysis. The mechanism of Kin repolarizing M1 macrophages was evaluated by Western blot. Further, macrophage conditioned medium (CM) and IL-1 were administered to chondrocytes. Micro-CT scanning and histological observations were conducted on anterior cruciate ligament transection (ACLT) mice with or without Kin treatment. We found that Kin repolarized M1 macrophages to the M2 phenotype. Mechanistically, Kin inhibited the phosphorylation of IB, which further reduced the downstream phosphorylation of P65 in nuclear factor-B (NF-B) signaling. Moreover, Kin inhibited mitogen-activated protein kinases (MAPK) signaling molecules p-JNK, p-ERK and p-P38. Additionally, Kin attenuated macrophage CM and IL-1-induced chondrocyte damage. , Kin reduced the infiltration of M1 macrophages, promoted M2 macrophages in the synovium, inhibited subchondral bone destruction and reduced articular cartilage damage induced by ACLT. All the results indicated that Kin is an effective therapeutic candidate for OA treatment.
