Objective To study the correlation of serum cardiac troponin levels and cardiovascular events in elderly type 2 diabetes patients,and provide the basis for prevention and treatment of cardiovascular disease combined with type 2 diabetes mellitus.Methods Totally 200 elderly type 2 diabetes patients were selected in the First Affiliated Hospital of Zhengzhou University,and divided into cardiac troponin-positive and negative groups according to serum cardiac troponin levels.The incidence of cardiovascular events and mortality was compared between the two groups.Results The levels of fructosamine and hemoglobin in cardiac troponin-positive group were significantly lower than those of cardiac troponin-negative group (P＜0.05).The C-reactive protein levels were increased in cardiac troponin-positive versus negative group (P ＜0.05).The incidences of cardiovascular events and mortality in cardiac troponin-positive group showed higher than those of cardiac troponin-negative group[63.3％ (19/30)vs.4.1 ％ (7/170),26.7％ (8/30) vs.1.2％ (2/170),x2 =73.45,28.44,all P＜0.05].Conclusion Lower levels of serum fructosamine and hemoglobin,higher C-reactive protein level exist in diabetes patients with high cardiac troponin levels.The serum cardiac troponin level has a certain relationship with cardiovascular events in diabetes patients.

Objective To investigate the clinical effect of mosapride combined acupoint massage on diabetic gastroparesis(DGP)in elderly patients with type 2 diabetes.Methods 150 cases of DGP in our hospital from April 2015 to May 2016 were collected and randomly divided into three groups:the conventional treatment group(n=35,in insulin treatment),the control group(n=52,in mosapride treatment),and the experimental group(n=63,in mosapride combined with acupoint massage treatment).All patients received the conventional diabetic therapy.Clinical efficacy,gastric emptying rate and the levels of serum gastrin and fasting blood glucose were observed and compared before versus after treatment among the three groups.Results After treatment,the total effective rate was 92.1% in the experimental group,versus 51.4% and 73.1% in the conventional treatment group and control group respectively,showing a statistically significant difference(P<0.05).There were significant differences in gastric emptying rate,the levels of serum gastrin and fasting blood glucose among the 3 treatment groups before versus after treatment.And gastric emptying rate,the levels of serum gastrin and fasting blood glucose were improved in the experimental groups compared with the conventional treatment and control groups(all P<0.05).The follow-up results showed that the adverse reactions and the recurrence rates were significantly lower in the experimental group than in conventional treatment group and control group(all P<0.05).Conclusions Mosapride combined with acupoint massage in the treatment of diabetic gastroparesis have significant clinical effect,low recurrence rate and high safety,and is worthy of promotion.

Objective To investigate the prevalence and features of thyroid nodules in middle and aged patients with type 2 diabetes mellitus(T2DM). Methods High-resolution ultrasonography was used to detect thyroid nodules in 132 cases middle and aged patients with type 2 diabetes and 89 patients without diabetes.The nodule features and its relationships with related indicators in diabetic patients were analyzed. Results The prevalence of thyroid nodules in middle and aged patients with type 2 diabetes was higher than that without diabetes (67.4％ vs. 53.9％,P＜0.05),and most occurred in 50 to 59 age group (66.7％ vs. 42.9％) without dependence on changes in thyroid functions and volumes.In diabetes group,the prevalence of thyroid nodules were 59.5％ in male and 81.3％ in female (P＜0.05),no obvious difference was observed in the size and number of thyroid nodules between male and female,multiple nodules and micronodule (＜ 1.0 cm) had the higher incidences in both sexes.The prevalence of thyroid nodules was increased with aging,but not with diabetes duration and glycosylated hemoglobin (HbAlc) level (x2 =0.797,P=0.372; x2 =1.078,P =0.229). Conclusions It is common that thyroid nodules combined with diabetes in middle and aged patients,thyroid ultrasound screening and regular following-up of patients aged ≥50 years have important clinical significance.

Objective To explore the relationship between serum osteocalcin levels and glucolipid metabolism in elderly type 2 diabetic patients with non-alcoholic fatty liver disease (NAFLD).Methods Data collected from 97 patients with type 2 diabetes mellitus(T2DM)admitted to the Department of Geriatric Endocrinology of the First Affiliated Hospital of Zhengzhou University from June 2014 to April 2015 were retrospectively analyzed.Patients were divided into the T2DM group(type 2 diabetic patients without NAFLD,n＝ 47)and the NAFLD group(T2DM patients with NAFLD,N ＝ 50).Healthy elderly subjects (n ＝ 30)from the same period served as the control group.Body mass index(BMl),osteocalcin,fasting blood glucose,fasting insulin,homeostasis model assessment for insulin secretion index (HOMA-β) and insulin resistance (HOMA-IR),glycosylated hemoglobin(HbA1c),total cholesterol,triglyceride,high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL C)were compared between the 3 groups.Results Levels of fasting blood glucose,fasting insulin,HbAlc,total cholesterol,triglyceride,LDL-C and HOMA IR were higher,while levels of HDL-C,HOMA-β and osteocalcin were lower in the T2DM and NAFLD groups than in the control group(all P＜＜0.05).Levels of BMI,fasting glucose,fasting insulin,HbAlc,total cholesterol,triglyceride,LDL-C and HOMA-IR were higher and levels of osteocalcin were lower in the T2DM group than in the NAFLD group(all P＜0.05).Pearson correlation analysis showed that the osteocalcin level was negatively correlated with fasting blood glucose,HbA1C,HOMA IR and BMI(r＝-0.701,0.442,-0.337 and 0.543,P＜0.05 or P＜0.01),and positively correlated with HOMA-β (r ＝ 0.341,P ＜ 0.05) in the NAFLD group.With serum osteocalcin as the dependent variable,multiple linear regression results showed that fasting blood glucose was an independent influencing factor for serum osteocalcin(β＝-1.57,P＜0.05)in the fatty liver group.Conclusions Serum osteocalcin levels significantly decrease in elderly T2DM patients with NAFLD,are closely correlated with glucolipid metabolism,and may have some important clinical significance in the prevention and treatment of NAFLD in elderly patients with type 2 diabetes.

Objective To investigate the characteristics of the blood glucose fluctuation in elderly patients with type 2 diabetes mellitus (T2DM). Methods The 92 elderly patients with T2DM (the elderly group) and 58 young and middle-aged patients with T2DM (the non-elderly group) were monitored using the continuous glucose monitoring system(CGMS). The characteristics of glucose profiles of the two different age groups, and of the different glycosylated hemoglobin (HbA1c) level groups in the elderly were comparatively analyzed. Results (1)There was no significant difference in HbA1c level between the elderly group and the non-elderly group. Compared with the non-elderly group, the elderly group showed the increases in blood glucose fluctuant coefficient [BGFC, (2.68±1.00) mmol/L vs. (2.12±0.74) mmol/L, t=-3.691, P＜0.001], in postprandial glucose excursion (PPGE) of breakfast and supper [(5.96±2.47) mmol/L vs. (5.11±2.44) mmol/L, t=-2.058, P＜0.05; (5.17±2.15) mmol/L vs. (4.16±2.28) mmol/L, t=-2.730, P＜0.01], in the time to postprandial glucose peak of breakfast and lunch [(112.5±29.7) min vs. (97.0±27.2) min, t=-3.225, P＜0.01; (140.0±39.7) min vs. (118.1±42.6) min, t=-3.195, P＜0.01], in the frequency of hypoglycemia (26.3% vs. 5.5%, P＜0.05), and showed the largest amplitude of glycemic excursions [LAGE, (9.66±2.48) mmol/L vs.(8.40±3.13) mmol/L, t=-2.720, P＜0.01]. (2)In the elderly, along with decreased HbA1c, the incidence of hypoglycaemia increased (P＜0.05); And along with increased HbA1c, the amplitude of blood glucose fluctuation increased. There were significant differences in BGFC, PPGE of breakfast and lunch, and LAGE among different HbA1c level groups (P＜0.01, P＜0.05, P＜0.05, P＜0.001). (3)HbA1c was positively correlated with FBG, mean blood glucose (MBG), percentage of time at glycemia (PT7.8, PT11.1), the lowest blood glucose (LBG), the highest blood glucose (HBG), BGFC, PPGE and LAGE (r=0.899-0.289, all P＜0.001). Multiple stepwise regression analysis indicated that MBG, FBG and PT7.8 was the independent influential factor of HbA1c (adjusted R2=0.807, P＜0.05). Conclusions The elderly patients with T2DM are at a particularly high risk for postprandial hyperglycemia and nocturnal hypoglycemic episodes, CGMS could show glucose fluctuation characters of T2DM patients diurnally, and provide a clinical basis for reasonable therapy.

Objective To study the effect of maternal subclinical thyroid abnormalities [including subclinical hypothyroidism, hypothyroxinemia and positive anti-thyroid peroxidase antibody (TPOAb) with normal thyroid function] in women during 16-20 weeks of gestation on offspfing's intellectual development and motor function. Methods Sera from 1 268 women during 16-20 weeks of gestation (collected 2 years ago) were obtained and thyroid stimulating hormone (TSH), total thyroxine (TT4), free thyroxine (FT4) and TPOAb levels were measured. Pregnant specific thyroid function reference ranges were used to screen for subclinical hypothyroidism (18 cases), hypothyroxinemia (19 cases) and positive TPOAb (34 cases). From the same cohort, a total of 142 pregnant women who were euthyroid with negative TPOAb were selected as controls (a case: control ratio of 1 : 2). Intellectual and motor development score evaluations were performed in their children at 25-30 months of age. Results In the group of pregnant women with subclinical hypothyroidism, the offspring' s intelligence score was (109.89±13.81) points, which was 8.88 points lower than in the control group (P < 0.01). Similarly, the motor score of the offspring was (108.11±9.93) points, which was 9.98 points lower than in the control group (P < 0.01). In the pregnant women with hypothyroxinemia, the offspring's intelligence score was (112.32±15.10) points, 9.30 points lower than in the control group (P <0.01); the motor score was (112.21±12.26) points, 7.57 points lower than in the control group (P < 0.01). In the pregnant women with positive TPOAb and euthyroid function, the offspring's intelligence score was (112.70±20.64) points, 10.56 points lower than in the control group (P < 0.01); the motor score was (110.64±12.49) points, 9.03 points lower than in the control group (P < 0.01). Conclusion Maternal subclinical thyroid abnormality between 16-20 weeks of gestation adversely may affect offspring intellectual and motor development, suggesting the necessity for screening and treatment of maternal subclinical thyroid abnormality in the early stages of pregnancy.

Objective To investigate the correlation between the expression levels of miRNAs and the pathogenesis of diabetes mellitus.Methods A total of 120 patients with type 2 diabetes recruited from October 2014 to October 2016 and 40 healthy individuals as a control group were included in this study,and diabetic patients were further divided into newly diagnosed group(n=40),prediabetes group(n =40),and susceptibility group (n =40).The fasting blood of four groups were collected,and real-time RT-PCR was applied to measure the expression levels of miRNAs including miR-9,miR-124a,miR-375,miR-29a,miR-126,miR-197,miR-233,and miR-320.The relationship between the pathogenesis of disease and miRNAs expression levels was analyzed.Results The levels of miRNA in the three diabetes groups were obviously higher than in the control group(P＜ 0.05).The miRNA expression level showed a certain trend in diabetic patients.The higher levels of miR-9,miR-124a,miR-375,and miR-29a were observed in the three diabetes groups,while the levels of miR-126,miR-197,miR-233,and miR-320 were decreased in these three groups.The expression levels of miR-9,miR 124a,miR-375,and miR-29a of miRNAs were correlated with the onset of diabetes(RR =5.96,6.32,5.24.5.69,all P＜ 0.05).Conclusions The level of miRNA is associated with the onset of diabetes that suggests it may be used to predict the occurrence and development of diabetes.

Objective To investigate the clinical effect of Metformin on inflammation,intestinal flora imbalance,and metabolic impairment in elderly patients with type 2 diabetes mellitus(T2DM) Methods A total of 74 elderly patients with T2DM admitted to our hospital from October 2014 to October 2016 were included in this study and assigned into an intervention group(n=37)and a control group(n=37)according to the sequence of admission.The intervention group was treated with 0.5 g Metformin once a day for 2 weeks,while the control group was given a placebo with the same frequency as in the intervention group.Fresh pre-and post-treatment stool samples were collected in sealed sterile anaerobic growth bags for the detection of changes in patient intestinal flora.Serum inflammatory factor levels,blood glucose levels,and blood lipid levels were measured.Results Before treatment,the numbers of beneficial intestinal flora(bacillus bifidus,bacillus acidi lactici,and bacteroides)in the intervention group were lower than in the control group(all P＜0.05);The levels of serum inflammatory factors(CRP,IL-6,and TNF-α)in the intervention group were higher than in the control group(all P ＜0.05);The levels of parameters for glucose and lipid metabolism(HbA1c,FPG,TC,TG,and LDL-C)in the intervention group were higher than in the control group,while the level of HDL-C was lower than in the control group (all P ＜ 0.05).After treatment,the number of beneficial intestinal flora significantly increased in the intervention group(all P＜0.05)but was not different from that in the control group(all P＞0.05);The levels of serum inflammatory factors had significant reductions in the intervention group compared with pre-treatment levels(all P＜0.05)but demonstrated no difference from those in the control group(all P＞0.05);Parameters for glucose and lipid metabolism in the intervention group showed improvement(all P ＜0.05)after treatment but no difference was observed between these two groups(all P＞0.05).Conclusions Metformin can effectively control blood glucose and blood lipid levels in elderly patients with T2DM,improve the chronic inflammatory state,increase the number of beneficial intestinal bacteria,and regulate flora imbalance.
