Objective To investigate the clinical effect of intra-articular injection of sodium hyaluronate combined with psychological intervention in the treatment of knee osteoarthritis.MethodsA total of 90 patients with knee osteoarthritis treated in our hospital from June 2015 to June 2016 were selected as the research object, according to the different treatment methods, the patients were divided into two groups,with 45 cases in each group.The patients in the control group were treated with conventional treatment, while the observation group was treated with conventional therapy and intra-articular injection of sodium hyaluronate.The experimental data of the two groups were compared.ResultsAfter treatment, the changes of knee joint pain score, joint effusion and joint mobility in the observation group is better than those in the control group.The change of knee function score in the observation group was better than that in the control group.The clinical therapeutic effect of the observation group (95.6%) is better than that of the control group (75.6%);There was significant difference between the two groups (P<0.05);There were no serious adverse reactions in the two groups of patients receiving treatment,and there was no significant difference between the two groups.ConclusionThe clinical effect of intra-articular injection of sodium hyaluronate combined with psychological intervention in the treatment of knee osteoarthritis is good, which is worthy of clinical application.

OBJECTIVE:To observe the efficacy and safety of metformin in the treatment of type 2 diabetes(T2DM) with non-alcoholic fatty liver disease(NAFLD). METHODS:106 patients with T2DM with NAFLD were randomly divided into control group and observation group. Control group was received health education about T2DM with NAFLD and living intervention(diabe-tes diet and physical therapy);observation group was additionally given Metformin tablet 0.5 g,orally,3 times a day. The treat-ment course for both groups was 12 weeks. Clinical efficacy,and liver fat content,BMI,FPG,IR,TG,TC,LDL-C,HDL-C,HbA1c before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:After treatment,liver fat con-tent and related index in 2 groups were significantly better than before(except HOMA-IR in control group),and observaton group was better than control group,the differences were statistically significant(P<0.05). The total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). CONCLUSIONS:Based on the conventional treatment,metformin has good efficacy and safety in the treatment of T2DM with NAFLD.

Objective To investigate abdominal visceral fat area and its relationship with insulin resistance in male patients with type 2 diabetes and normal body mass index (BMI).Methods Seven male patients with type 2 diabetes and normal BMI were divided into two groups according to the abdominal visceral fat area (VFA) measured by CT:visceral obesity group (VFA ≥ 100 cm2) and non-visceral obesity group.Indicators of glucose and lipids metabolism were measured in two groups.Results Among 70 patients 50 (71％) had visceral obesity.In 59 patients who had normal BMI and normal waist circumference (≤90 cm),41 presented visceral obesity (69％).Compared with non-visceral obesity group,the waist circumference,homeostasis model assessment of insulin resistance (HOMA-IR),triglyceride,and VFA were significantly higher in visceral obesity group [(86.4 ± 5.6) vs.(81.2 ± 4.8) cm,t =-2.980,P ＜ 0.01;2.83±2.31 vs.2.01±1.30,t=-2.025,P＜0.05;1.93(1.26-2.79) vs.1.11(0.75-1.46) mmol/L,Z=-3.777,P＜0.01;(143.6 ±31.8)vs.(73.7 ±17.3)cm2,t =-11.456,P＜0.01].Fasting insulin,fasting plasma glucose and glycosylated hemoglobin tended higher in visceral obesity group but not significantly (P ＞ 0.05).Multiple linear regression analysis showed that after adjustment for age and body mass index,abdominal VFA was positively correlated with HOMA-IR (r =0.240,P ＜ 0.05).Conclusion Male type 2 diabetic patients have a high rate of visceral obesity even when their body mass index and waist circumference are normal.Abdominal visceral fat area is closely associated with insulin resistance.

Objective To investigate the association of serum levels of soluble intercellular cell adhesion molecule-1 (sICAM-1),soluble vascular cell adhesion molecule-1 (sVCAM-1) and high sensitivity C-reactive protein (hs-CRP) with peripheral vascular disease of lower limbs in patients with type 2 diabetes mellitus (T2DM).Methods One hundred and thirty T2DM patients admitted from October 2011 to October 2012,and 30 age/sex-matched healthy subjects were enrolled in the study.The serum levels of sICAM-1,sVCAM-1,hs-CRP and other clinical parameters were measured; the peripheral blood vessels of lower limbs were examined with color Doppler ultrasonography.Based on the extent of angiopathy of lower limbs T2DM patients were classified as normal vascular group (n =26),mild angiopathy group (n =45),moderate/severe angiopathy group (n =59).Results The serum levels of sICAM-1 and sVCAM-1 in moderate/ severe angiopathy group of T2DM patients were higher than those in mild angiopathy group,normal vascular group and healthy controls (t:4.15-8.93,all P ＜0.05) ; the serum levels of hs-CRP in moderate/severe angiopathy group were higher than those in mild angiopathy group,normal vascular group and healthy controls (t:2.18-4.27,all P ＜ 0.05).The serum sICAM-1 level was positively correlated with total cholesterol (TC),low density lipoprotein cholesterol (LDL-C) and sVCAM-1.The serum sVCAM-1 level was positively correlated with course of disease,systolic blood pressure and CRP.Conclusions Serum levels of sICAM-1,sVCAM-1 and hs-CRP are correlated with the extent of angiopathy of lower limbs in T2DM patients,and the elevated sICAM-1 ; sVCAM-1 and hs-CRP levels are also associated with hyper blood pressure,dislipidemia and chronic inflammation.

Objective To investigate the association of serum visfatin and free fatty acid (FFA) with insulin resistance in type 2 diabetes mellitus (T2DM).Methods One hundred and nineteen patients with T2DM and 65 health subjects with normal glucose tolerance (NGT) were enrolled in the study.TheT2DM patients were further classified as insulin resistant (HOMA-IR ＞ 2.8 mU/L,T2DM-IR group,n =61) and non-insulin resistant (HOMA-IR≤2.8 mU/L,T2DM-NIR group,n =58).Serum visfatin,free fatty acid and related clinical variables were measured,and HOMA-IR was calculated.Results The serum levels of visfatin and FFA in T2DM patients were significantly higher than those in healthy controls [(4.7 ±2.5) vs.(1.7±0.9) ng/L,t=-11.831,P＜0.01; (1.65±0.69) vs.(0.61 ±0.21) mmol/L,t=-9.239,P ＜0.01].The serum levels of visfatin and FFA in T2DM-IR group were significantly higher than those in T2DM-NIR group [(6.3±2.3) vs.(3.0±1.4) ng/L,P＜0.01; (2.16±0.45) vs.(1.12± 0.46) mmol/L,P ＜0.01].Multiple regression analysis showed that FFA,fasting insulin level and waist/ hip ratio (WHR) were independent risk factors of serum visfatin level (r =0.564,0.267 and 0.188 respectively,all P ＜ 0.05).Conclusion Serum levels of visfatin and FFA are increased in T2DM,and they are closely associated with insulin resistance.

Objective To investigate the prevalence of overweight,obesity and related metabolic diseases among male public institution office workers in health check-up.Methods Total 1 018 male public institution office workers aged 23-60 underwent annual health check-up at our hospital in 2012.The data including blood pressure,waist circumference,height,body weight,serum glucose,plasma lipids and serum uric acid were analyzed.According to body mass index (BMI),the subjects were classified as:underweight(BMI ＜ 18.5 kg/m2),normal weight (18.5 kg/m2 ≤ BMI ＜ 24 kg/m2),overweight (24 kg/m2 ≤ BMI ＜ 28 kg/m2) and obesity(BMI≥28 kg/m2).Results The prevalence of overweight,obesity,central obesity and metabolic syndrome (MS) were 40.9％ (416/1 018),7.9％ (80/1 018),53.0％ (540/1 018),and 11.2％ (114/1 018),respectively.There were significant differences in fasting blood glucose (FPG),TC,TG,uric acid(UA),systolic blood pressure(SBP) and diastolic blood pressure(DBP) levels among different groups (F =4.82,12.09,40.55,6.19,28.97 and 49.29,respectively,all P ＜0.01).The prevalence rate of hypertension in underweight,normal,overweight and obesity groups was 0,11.8％,27.4％ and 37.5％,respectively; that of diabetes was 0,1.6％,5.5％ and 10.0％,respectively; that of hyperlipidemia was 40.0％,47.2％,66.3％ and 71.2％,respectively; that of hyperuricemia was 0,5.0％,13.5％ and 13.8％,respectively,which showed that with the increasing of BMI,the prevalence rates of related metabolic diseases were increased(x2 =55.97,9.65,43.32 and 24.08,all P ＜0.01).And the co-morbidity rate with ≥3 diseases in 4 BMI groups were 0(0/20),1.4％ (7/502),5.8％ (24/416) and 13.8％ (11/80),respectively (x2 =31.90,P ＜ 0.01).Conclusion Obesity and overweight are correlated with metabolic disorders and the obese subjects are at high risk for cardiovascular diseases.

The effect of Selenium(Se) on regression of atherosclerosis(AS) induced by feeding quails -with high cholesterol diet was observed. The result indicated that serum cholesterol, triglyceride and lipid peroxide significantly decreased and the ratio of high density lipoprotein cholesterol/total cholesterol increased markedly in Se treated group, that the cholesterol content of aortic tissue and AS index were significantly reduced at the end of the 15th week. It was suggested that Se had a powerful accelerated effect on regression of experimental AS.
