ObjectiveTo investigate the in vivo effects of down-regulating the FGF-21 gene expression by shRNA on glucose and lipids metabolism in high fat diet (HFD) fed ApoE-/- mice.MethoedsMale ApoE-/- mice were randomly divided into chow diet (CF)fed group ( NF,n =10),CF fed + pAd-shFGF-21 group ( NFG,n =9),and HFD fed group ( HF,n =10),HFD fed + Adv-null vector ( pAd-GFP ) group ( GFP,n =6) and HFD fed + pAd-shFGF-21 group ( HFG,n =10).Mice were fed for 16 weeks.C57BL/6J mice were set as control group ( NC group,n=10).NFG,HFG,and GFP groups were injected with pAd-shFGF-21or pAd-GFP by tail vein at the end of 15 weeks.The insulin sensitivity and glucoselipid metabolism were assessed by the hyperinsulinemic- euglycemic clamp technique using 3-[ 3 H] glucose as a tracer at the end of 16 week.ResultsThe plasma FGF-21 levels in NFG and HFG groups were significantly degraded than those in NF and HF groups(20％-27％,P＜0.05),respectively.In the basal state,the fasting blood glucose,fasting plasma insulin,free fatty-acids,triglycerides,total cholesterol,and LDL-C were significantly higher,while the HDL-C was lower in NFG and HFG groups compared with those in NF and HF groups,respectively (P＜0.05 or P＜0.01 ).During the steady-state of clamp,FFA was suppressed in all groups,but it was still higher in NFG and HFG groups than NF and HF groups ( P＜0.05or P＜0.01 ).The glucose infusion rate (GIR)and glucose disappearance rate (GRd)in NFG and HFG groups were significantly decreased compared with NF and HF groups (all P＜0.01 ).In addition,insulin's ability to suppress hepatic glucose production (HGP) during clamps was significantly decreased in HFG and NFG group compared with HF and NF groups (49％ and 20％,respectively; all P＜0.01 ).ConclusionFGF-21 knockdown and low FGF-21 level facilitate the development of metabolic disorder and insulin resistance.

Objective To evaluate the reliability and validity of the Chinese version of the Diabetes,Hypertension and Hyperlipidemia(DHL) Knowledge Instrument in community diabetic patients.Methods A face-to-face interview was conducted among 513 patients with diabetes in the community from January to March 2016 by using the Chinese version of DHL Knowledge Instrument.Forty of them were randomly sampled and reinvestigated 4 weeks later.The analyses on Cronbach's α coefficient,test-retest reliability,content validity,discriminant validity and construct validity were performed to evaluate reliability and validity of the DHL Knowledge Instrument.Results The qualified questionnaires were collected from 488 participants,including 232 males and 256 females with a mean age of (66 ± 6)years.The overall scores of the Chinese version of DHL Knowledge Instrument was 67.7 ± 18.0 and the scores of diabetes,hypertension,hyperlipidemia,medications and general issues sub-scales were 82.0 ± 22.5,65.9 ± 25.2,38.2 ± 34.3,75.5 ± 20.8 and 72.1 ± 22.9,respectively.The standardized Cronbach's α coefficient of the total scale was 0.849 and the test-retest reliability of the total scale was 0.706 (P ＜ 0.01).In term of content validity,the correlation coefficient was from 0.580 to 0.827 among total scale and sub-scales (P ＜ 0.01).In term of discriminant validity,the difference between the high and the low score group on total scale and sub-scales were significant (t value =-13.486 to-35.528,all P ＜ 0.01).In term of construct validity,based on exploratory factor analysis,the scale was revised.According to confirmatory factor analysis of revised scale,four factor model containing 20 items was well fitted (X2 =159.689,df =134,P =0.064);the GFI (goodness of fit index) =0.966,AGFI (adjusted goodness of fit index) =0.952,RMSEA (root mean square error of approximation) =0.020.Conclusion The Chinese version of DHL Knowledge Instrument possesses good reliability and validity and is suitable to evaluate the knowledge of community diabetic patients,and the modified version may work better than the original one.

Objective: To observe the effect of moxibustion on the expressions of tumor necrosis factor-α (TNF-α) and nuclear transcription factor kappa B (NF-κB) proteins in ankle joints of rats with rheumatoid arthritis (RA), and to explore the anti-inflammatory mechanism of moxibustion in the treatment of RA.Methods: Adjuvant arthritis (AA) rat models were induced and used as rat models of RA. Rats were randomly divided into a normal group, a model group, a moxibustion group and a saline group. Rats in the normal and model groups were not treated; rats in the moxibustion group accepted treatment by moxibustion at Zusanli (ST 36) and Shenshu (BL 23) after modeling; rats in the saline group were injected with 0.15 mL saline to the bottom of the left hind paw and had no other treatments. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes of rats' ankle joints under light microscope. Immunohistochemistry was used to observe the expressions of TNF-α and NF-κB in ankle joints of rats.Results: Compared with the normal group, the rats' ankle joints in the model group showed disorganization, joint surface defect, and significantly increased mean optical density (MOD) of TNF-α and NF-κB (allP<0.05). After moxibustion treatment, rats in the moxibustion group showed repaired ankle tissues, smooth joint surface without defects, decreased MOD of TNF-α and NF-κB than those in the model group (allP<0.05). Rats in the saline group had no damage to ankle joints, while TNF-α and NF-κB were significantly different from those in the model group (P<0.05).Conclusion: Moxibustion could down-regulate the expressions of NF-κB and TNF-α protein in ankle joints of RA rats, and produce an anti-inflammatory effect to promote tissue repair.

Objective To assess the effect of community management of type 2 diabetes mellitus (T2DM)patients with signing on family doctor service in Shanghai.Methods Six community health service centers in two Shanghai districts were selected by cluster random sampling method from April 2014 to March 2017.T2DM patients,who visited the community health service centers more than three times in the last one year, were enrolled in the study.The questionnaire survey was conducted and lab tests were documented.Results A total of 5 078 T2DM patients were enrolled in this study,among whom 2 033 had signed contract service with family doctors(signing group)with a signing rate of 40.8%.Compared to non-signing group,the patients in the signing group were better followed the recommendations of blood glucose control[64.6%(1 320/2 053)vs.35.7%(1 061/2 978)], diet[64.6%(1 320/2 053)vs.35.7%(1 061/2 978)]and physical activity[63.4%(1 295/2 053)vs.34.8%(1 033/2 978)](χ2=356.507, 400.649 and 393.996, P<0.01).The medication compliance rate and regular exercise rate in signing group were higher than those in non-signing group[80.2%(1 615/2 053)vs.77.6%(2 272/2 978), χ2=3.894,P<0.05;81.8%(1 679/2 053)vs.74.5%(2 215/2 978),χ2=38.084, P<0.05]. The control rates of GLU,2 h PPG,HbA1c,and blood pressure in signing group were higher than those in non-signing group[40.0%(823/2 053)vs.35.9%(1 069/2 978),47.3%(971/2 053)vs.45.4%(1 352/2 978),35.2%(722/2 053)vs.32.5%(968/2 978), χ2=18.495,5.218, 5.006, all P<0.05].Conclusion The community management with signing on family doctor service enhances the improvement of health related behaviors in patients with type 2 diabetes; but currently the rate of contract signing is still low.

Objective To analyze the risk factors of microvascular complications in patients with type 2 diabetes mellitus (T2DM).Methods The demographic and clinical data of 5078 T2DM patients in six communities of Shanghai were collected during September 2014 to April 2015. The risk factors of microvascular complications in T 2DM were analyzed by classification tree model .Results Among 5078 T2DM patients there were 1007 cases of diabetic retinopathy (DR) (21.1%) and 1937 cases of diabetic nephropathy (DN) (38.4%).The classification tree models showed that the risk factors of DR were higher hemoglobin A1C ( HbA1c), fasting blood glucose ( FBG), postprandial blood glucose ( PBG) and triacylglycerol ( TG) levels;longer course of disease and younger age of onset .The model showed that the risk factors of DN were higher HbA1c, FBG, hypertension, PBG, body mass index ( BMI ) and triacylglycerol (TG) levels;and lower high-density lipoprotein (HDL) level.The HbA1c, course of disease and PBG were more closely related to DR and HbA 1c, hypertension and FBG were more closely related to DN.Conclusion HbA1c is the most important risk factor to microvascular complications; FBG and PBG are independent risk factors of microvascular complications;the course of disease and hypertension are risk factors of DR and DN , respectively .

Objective:To survey on the status quo of the management capabilities of general practice team leaders in community health service centers in Shanghai.Methods:Using stratified sampling method, 18 community health service centers in the urban and suburban areas of Shanghai were selected, then the general practice team leaders and general practitioners (team members) in the centers were selected as the study participants. The questionnaire survey on the management capabilities of general practice team leaders was conducted among selected participants from November to December 2021. The self-assessment by general team leaders and the other-assessment by team members were carried out, and the total scores was calculated according to the weight of self-evaluation score (30%) and other-evaluation score(70%).Results:A total of 110 general practice team leaders and 749 team members participated in the survey. Among the team leaders, 63.64% (70/110) were females, 82.73% (91/110) were bachelor degree holders, 71.82% (79/110) had intermediate professional title, and 50.91% (56/110) worked for more than 9 h per day. The total score of general practice team leaders was (87.15±10.76) points, the other-assessment score was significantly higher than self-assessment score ((88.62±9.34) vs.(83.71±14.08), t=2.22, P<0.05). The average score of the 5 dimensions was 4.41 for special business management, 4.39 for organizational management, 4.38 for personal quality, 4.27 for teaching and research management and 4.22 for strategy and cultural construction, respectively. Conclusion:The overall management capabilities of Shanghai community general practice team leaders are at the upper-middle level, however, the capabilities in scientific research and team planning are relatively weak.

Objective:To analyze the relationship between capacity of general practice team leaders and the team performance in community health service centers.Methods:This study was a cross-sectional study. A questionnaire survey was conducted between November and December 2022, among general practice team leaders and general practitioners (GPs) from 18 community health service centers in the urban and suburban areas of shanghai selected by stratified sampling method. The personal information questionnaire, leadership of general practice team leader questionnaire,and work performance scale of general team members were used for the survey. The relationship between leadership of general practice team leaders and team performance was analyzed based on structural equation model (SEM).Results:A total of 944 questionnaires were distributed and 856 valid ones were returned with a response rate of 91.0%, including 110 general practice team leaders and 749 were GPs. The SEM analysis showed that some dimensions of the management ability of the general practice team leader had significant effect on the employee organization loyalty (organizational management: β=0.37, teaching and research management: β=-0.29, strategy and cultural construction: β=0.23, personal quality: β=0.11) and work performance (special business management: β=0.95, organizational management: β=0.54) (all P<0.05); and employee organization loyalty played a partial mediator role in relationship between leadership of general practice team leaders and work performance with a mediating effect of 39.50%. Conclusion:The management ability of the general practice team leader directly affect or indirectly affect the work performance of team members through team members′ organizational loyalty.

Objective: To study the molecular features of metanephric adenoma (MA) and discuss their values in differential diagnosis. Methods: BRAF V600E immunohistochemistry (IHC) using the mutation-specific VE1 monoclonal antibody and Sanger sequencing of BRAF mutations were performed on 21 MAs, 16 epithelial-predominant Wilms tumors (e-WT) and 20 the solid variant of papillary renal cell carcinomas (s-PRCC) respectively. p16 protein was detected by IHC also. Fluorescence in situ hybridization (FISH) analyses using centromeric probes for chromosome 7 and 17 were performed on the three renal tumors in parallel. Results: Fourteen (14/21, 66.7%) of 21 MA cases demonstrated diffuse, moderate to strong cytoplasmic BRAF V600E IHC staining and the BRAF V600E protein expression was detected in 2 (2/16) of 16 e-WT cases for the first time, whereas all s-PRCCs were negative (P<0.05). All cases (including 14 MAs and 2 e-WTs) with diffuse, moderate to strong cytoplasmic BRAF V600E IHC staining were confirmed to harbor BRAF V600E missense mutations using Sanger sequencing, and no BRAF mutations were detected in cases with negative BRAF V600E protein expression. One case (1/21, 4.8%) showed trisomy of chromosome 7 alone, and another one (1/21, 4.8%) showed trisomy of chromosome 17 alone in 21 MAs. Two cases (2/16) of 16 e-WTs showed trisomy of chromosome 17 alone. In 20 s-PRCCs, trisomy of chromosomes 7 alone was reported in 2 cases (2/20), trisomy of chromosome 17 alone in 3 cases (3/20) and trisomy of chromosome 7 and 17 in 14 cases (14/20). The total positive rates of trisomy of chromosome 7 and/or 17 in MAs, e-WTs and s-PRCCs were 9.6% (2/21), 2/16 and 95.0% (19/20). p16 protein was positive in 81.0% (17/21) MAs, whereas the positive rates in e-WTs and s-PRCCs were 2/16 and 5.0% (1/20). Conclusions Most MAs harbor BRAF V600E mutations, and MAs lack the gains of chromosome 7 and 17 that are characteristic of papillary renal cell carcinoma. These molecular features can be used to distinguish MA from its mimics. BRAF V600E IHC using the mutation-specific VE1 monoclonal antibody provides an effective method in BRAF V600E mutations detection of renal tumors. p16 is overexpressed in MA, and the finding suggests that the low proliferative rate of the tumor might be attributed to BRAF V600E-induced senescence mediated by p16.

Objective To investigate the outcomes of patients with diabetic retinopathy (DR) in Shanghai communities and the influencing factors.Methods From October 2015 to April 2016,533 type 2 diabetic patients with DR were selected by target sampling and cluster random sampling method from six community health service centers in Shanghai.Patients were followed up for 1 year.The demographic information,physical examination,laboratory tests and eye fundus exam results were documented and the DR was graded.The factors associated with the regression of DR were analyzed.Results Total 478 patients,including 280 females (58.6％) and 198 males (41.4％),were followed up for 1 year.The mean age of patients was (64±7) years and the mean disease duration was (8.85±4.20) years.The original DR lesion was remitted in 35 patients with an improvement rate of 7.3％;while the original DR lesion was aggravated in 29 patients with a progression rate of 6.1％.Ordinal logistic regression analysis revealed that age (OR=0.197,95％CI:0.056-0.699),body mass index (BMI) (OR=0.383,95％CI:0.171-0.856),glycosylated hemoglobin (HbAlc) (OR=0.287,95％CI:0.102-0.803),triglycerides (TG) (OR=0.541,95％CI:0.295-0.991),urinary albumin to creatinine ratio (ACR)(OR=0.218,95％CI:0.066-0.720) were associated with DR in type 2 diabetic patients.Conclusion The regression of DR is closely related to age,BMI,glucose,serum lipids and renal function,so it is suggested that lowering BMI,controlling glucose and serum lipids and maintaining normal kidney function are necessary for preventing the progression and promoting the improvement of DR in diabetic patients.
