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 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 the role of chemokine CXC-ligand 16 (CXCL16) in renal ischemia-reperfusion (I/R) injury in the mice.Methods Twelve healthy male C57BL/6 mice and 12 CXCL16-knockout (CXCL16-KO) mice,aged 8-10 weeks,weighing 20-30 g,were studied.The 12 C57BL/6 mice were randomly divided into 2 groups (n=6 each) using a random number table:C57BL/6 sham operation group (group C-S) and C57BL/6 I/R group (group C-I/R).The 12 CXCL16-KO mice were randomly divided into 2 groups (n=6 each) using a random number table:CXCL16-KO sham operation group (group KO-S) and CXCL16-KO I/R group (group KO-I/R).The right kidney was removed,and the left kidney was exposed,and the renal artery was then clamped for 45 min with atraumatic microclips followed by 24 h reperfusion to establish the model of renal I/R in anesthetized mice.Venous blood samples were taken at 24 h of reperfusion for determination of the serum blood urea nitrogen (BUN) and creatinine (Cr) concentrations.The renal specimens were obtained at 24 h of reperfusion for microscopic examination of the pathological changes,and the damage to the renal tubules was scored.The number of myeloperoxidase (MPO) positive cells (MPO+ cells),F4/80+ cells and CD3+ cells in renal tissues was counted by immunohistochemistry.The expression of tumor necrosis factor-alpha (TNF-α),interleukin-1beta (IL-1β),IL-6,and macrophage inflammatory protein-2 (MIP-2) mRNA in renal tissues was determined by real-time reverse transcriptase polymerase chain reaction.Results Compared with group C-S,the serum BUN and Cr concentrations,renal tubular damage score,and the number of MPO+,F4/80+,and CD3+ cells were significantly increased,and the expression of TNF-α,IL-1β,IL-6 and MIP-2 mRNA was significantly up-regulated in group C-I/R (P＜0.05).Compared with group KO-S,the serum BUN and Cr concentrations,renal tubular damage score,and the number of MPO+,F4/80+,and CD3+ cells were significantly increased,and the expression of TNF-α,IL-1β,IL-6 and MIP-2 mRNA was significantly up-regulated in group KO-I/R (P＜0.05).Compared with group C-I/R,the serum BUN and Cr concentrations,renal tubular damage score,and the number of MPO+,F4/80+,and CD3+ cells were significantly decreased,and the expression of TNF-c,IL-1β,IL-6 and MIP-2 mRNA was significantly down-regulated in group KO-I/R (P＜0.05).Conclusion CXCL16 is involved in the pathophysiological process of renal I/R injury in the mice.

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.

Objective:To assess the implementation of injection-related risk management based on WeChat platform for type 2 diabetic patients with the insulin self-injection.Methods:A total of 124 diabetic patients, who would receive insulin therapy by self-injection at home after discharge from the PLA 903 hospital during April 2017 to July 2018, were divided into the control group( n=62)and the study group( n=62). All patients were given routine education on insulin injection during the hospitalization,while the study group( n=62)received additional video and text education based on WeChat platform after discharge. The skill of self-injection and the status of blood glucose control were evaluated in both groups 4 weeks and 8 weeks after discharge, respectively. Results:The insulin injection skill, including skin disinfection [36(58%) vs. 11(18%),χ 2=21.42, P<0.01], exhaust before injection [62(100%) vs. 51(82%),χ 2=12.07, P<0.01], stay 10s after injection [60 (97%) vs. 47(76%),χ 2=11.52, P<0.01], disposal of used needle[49(79%) vs. 18(29%),χ 2=31.20, P<0.01], rotation of injection site [48(77%) vs. 35(56%),χ 2=6.16, P=0.01], insulin storage [62(100%) vs. 57(92%),χ 2=5.21, P=0.02], and the ability of correctly dealing with hypoglycemia [52(84%) vs. 38(61%),χ 2=7.94, P=0.01] in the study group were significantly better than those in the control group after 4 weeks of injection-related risk management. The fasting plasma glucose [(6.41±0.76) vs.(7.19±0.81)mmol/L, t=5.61, P<0.01], glycosylated hemoglobin A1c [(6.71±0.64)% vs. (7.37±0.78)%, t=5.18, P<0.01], incidence of hypoglycemia [6(10%) vs. 15(24%),χ 2=4.64, P=0.03] in the study group were significantly lower than those in the control group after 12 weeks of the management. Conclusion:The risk management based on WeChat platform can improve insulin self-injection skill and the ability of dealing with hypoglycemia,also promote effective blood glucose control for diabetes patients.

Objective To investigate the duodenum absorptive character of monosialotetrahexosylganglioside sodium (GM1) in rats.Methods The contents of phenolsulfonphthalein (as indicators) and GM1 were determined with ultraviolet-visible (UV) method and high performance liquid chromatography (HPLC) method in rats with in situ cycle intestinal perfusion model.Results The ratio of duodenum absorption of GM1 was 10％ in 2 h after cycle and 22％ in 6 h after cycle,respectively.The Ka was (0.030± 0.012)h,and absorption t1/2 was (25.50 ± 8.56)h in 8 h after cycle.Conclusions GM1 is absorption in rat duodenum,and the accumulate absorption of GM1 is almost linearly related to the cycle time.The absorption dynamics of GM1 may be first-order kinetic process.

Objective To evaluate the reliability, validity and feasibility of the Chinese version of SF-36 health survey questionaire in long-term survivors of nasopharyngeal carcinoma (NPC). Methods A total of 85 long-term NPC survivors completed the Chinese version of SF-36 by either telephone or mail survey. Correlation analysis, reliability analysis and factor analysis were performed to evaluate the reliability and validity of the scale. Results The Chinese version of SF-36 was easy to complete. The split-half reliability was 0. 92 and the Cronbach's α coefficient among domains were all above 0. 70, which showed good reliability and discrimination capacity among domains. All the correlation coefficients between each item and its domain achieved or approached 0. 5, which were greater than those between the item and other domains. These results demonstrated that the Chinese version of SF-36 had good content validity and discriminatory validity. Six principal components were extracted from the scale, which could basically represent eight domains. The cumulative variance was 71.4%. Two common factors were extracted from the eight domains, which accounted for 73.3% of the variance. The Chinese version of SF-36 was able to detect differences in the quality of life between NPC patients and healthy populations. Conclusions The Chinese version of SF-36 has good feasibility, reliability and validity in evaluating the quality of life in long-term NPC survivors.

Objective To analyze the effect of quality of life (QOL) on the prognosis of long-term survivors with nasopharyngeal carcinoma (NPC). Methods A total of 192 NPC patients treated between 1999 and 2000 and with tumor-free survival before July 2003 were enrolled in this study. All patients received QOL measurement between July and August in 2003. Measurement scales included Chinese SF-36 questionnaire and a checklist consisting of fourteen items about self-rating symptoms. The median follow-up time was 7.9S years (range 2.67-9.55 years). The effects of QOL, social demographic and clinical factors on prognosis were analyzed. Results Univariate analysis showed that QOL affected the tumor-free survival and overall survival. Multivariate analysis showed that hypomnesia was an independent prognostic factor of tumor-free survival, while trismus, headache and age were independent prognostic factors of overall survival. The younger and the better QOL had better prognosis. The other sociodemographic and clinical factors had no prognostic value. Conclusion QOL is an important factor affecting the prognosis of long-term survivors with NPC, and it should be routinely evaluated during the follow-up.
