The fasting blood glucose level (7.31±1.02) nmol / Lin the experimental group was significantly lower than that in the control group (7.90±0.82)nmol / L, with statistical difference (P<0.05). Urine glucose levels of patients in the experimental group was significantly better than the control group, with statistical difference (P<0.05). Conclusion The application of Tangniaole capsule assisted with metformin in newly diagnosed type 2 diabetic patients in can largely reduce blood glucose and urine glucose and insulin resistance level, with further clinical promotion and application significance.

BACKGROUND: Exercise-induced myocardial cell apoptosis and signal transduction and regulation mechanisms of sports medicine research have become an important issue, but remain poorly understood. Studies concerning the protective effect of bone marrow-derived mesenchymal stem cells (MSCs) to the exercise-induced myocardial cell apoptosis are rarely conducted.OBJECTIVE: To analyze the protective effect of MSCs on myocardial apoptosis and the exercise-induced myocardial cell apoptosis, so as to explore the pathological cause of exercise-induced myocardial apoptosis and the protective effects of MSCs on myocardial cell apoptosis induced by hypoxia, ischemia, and oxidative stress.METHODS: A computer-based online search of articles was performed in Medline database (1994-01/2009-09) with "Mesenchymal stem cells, Excessive exercise, Cardiomyocyte, Apoptosis" as key words and Chongqing PubMed Result NCBI database (1994-01/2009-09), Tsinghua Tong Fang database (1994-01/2009-06), with "bone marrow mesenchymal stem cells, over-training, myocardial cells, apoptosis" as key words. RESULTS AND CONCLUSION: A total of 365 articles on stem cells and exercise-induced myocardial apoptosis were collected, including 120 Chinese and 245 English. Outdate, repetitive and similar studies were excluded, and 68 were included. MSCs display a protection to myocardial cell apoptosis induced by hypoxia, ischemia and oxidative stress caused by high-intensity or overload exercise training, thereby contributing to the improvement of heart function and early rehabilitation of exercise-induced myocardial tissue diseases.

Objective To discuss the correlation between procrastination and the mentalities of anxiety and depression among medical postgraduates,so as to carry out mental health work effectively.Methods 423 medical postgraduates in Central South University were assessed randomly, using General Procrastination Scale (GPS),Self-rating Anxiety Scale(SAS),Self-rating Depression Scale (SDS).Results Procrastination score and incidence in medical postgraduates was 54.92±8.40 and 60.99%respectively,the differences of procrastination scores(53.3l±8.21,55.90±8.30,55.75±8.49,P=0.013)and incidences(52.60%,66.09%,65.58%.P =0.028)among three grades were statistically significant.Both total coarse score of anxiety and that of depressionwere higher than that of the whole country(31.24±7.40,29.78±10.07,P=0.000;34.8±8.11,33.46±8.55,P=0.000),the differences were statistically significant.Procrastination had a positive correlation with anxiety and depression significantly(r=0.304,P=0.000;r=0.369,P=0.000),the higher the grade was,the weaker the intensity of correlation was.Hish-delay group,low-delay group and normal-behavior group had different deglees of anxiety(46.63±10.55,44.01±10.12,38.32±7.57,P=0.000)and depression(51.45±10.12,47.81±10.78,40.69±8.23,P=0.000),which was statistically significant.Conclusion Anxiety and depression among medical postgraduates were outstanding and had a close relationship with procrastination behavior,which should be taken seriously and handled by strengthening mental health education.

AIM: To investigate the effect of puerarin on diabetic myocardial damage and to explore its possible mechanisms in rats. METHODS: The male Sprague-Dawley rats were randomly divided into normal control group, diabetic group, high dose puerarin (160 mg/kg), middle dose puerarin (120 mg/kg), low dose puerarin (80 mg/kg) treatment groups and aminoguanidine (100 mg/kg) treatment group. Corresponding drugs were intraperitoneally injected once a day. The animals in normal control group and diabetic group were given equal propylene glycol. 12 weeks later, the rats were sacrificed and their cardiac muscles were collected. Myocardial structure was observed under transmission electron microscope (TEM). The blood glucose concentration and the activities of superoxide dismutase (SOD), Ca~(2+)-ATPase, Na~+-K~+-ATPase and the content of malondialdehyde (MDA) in myocardial homogenate were measured biochemically. In addition, the mRNA expressions of peroxisome proliferator activated receptor γ (PPAR-γ), glucose transporter-4 (GLUT-4) and aldose reductase (AR) in myocardial tissues were determined by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: It is observed that the myofibrils were diminished, broken or fused, some lipid droplets deposited in the cytoplasm of cardiocytes and part of cristae of mitochondria were broken or disappeared under TEM in diabetic group. The activities of SOD, Ca~(2+)-ATPase, Na~+-K~+-ATPase as well as the mRNA expressions of PPAR-γ and GLUT-4 decreased significantly (all P<0.01). The blood glucose concentration and the MDA level and the AR mRNA expression increased obviously (all P<0.01) in diabetic group as compared to those in normal control group. How-ever, in puerarin treatment groups, the above changes were reversed, a significant differences of those were found as compared to those in diabetic group (P<0.05 or P<0.01, respectively). The pathological change of cardiac muscles was relieved. It showed that myofibrils were well-arranged and only few lipid droplets deposited in the cytoplasm of cardiocytes and most mitochondria had clear and regular cristae under TEM in puerarin treatment groups. CONCLUSION: Puerarin exerts preventive and remedial effects on the diabetic myocardium, which may be related to up-regulating the mRNA expressions of PPAR-γ and GLUT-4, promoting glucose uptake and relieving oxidative stress damage.

Objective: To explore the association between biomarkers and activities of daily living (ADL) in the elderly over 65 years old from longevity areas in China. Methods: A total of 2 439 people from 8 longevity areas were included in our baseline survey in 2012. Using questionnaires, body measurements, and blood biochemical examinations, information on demographics characteristic, life style, ADL, blood pressure and biomarkers were collected. Based on these six items of ADL (bathing, dressing, indoor activities, toileting, eating, bowel and bladder control), we constructed a dichotomous indicator for ADL. A respondent was defined as ADL disabled if any difficulty in one or more of the above six activities was reported. Information were collected in the follow-up in 2014 using the same questionnaires and examinations. We excluded information on the elderly who lacked ADL or biomarkers test results or with ADL disability at baseline study. Finally 938 elderly people over 65 years old were included in this analysis. Multivariate logistic regression model was used to analyze the influence factors of ADL disability. Results: During the 2-year follow-up, 100 (10.7%) participants developed into ADL disability, with a rate at 10.7%. Multivariate logistic regression analysis indicated that each year increase in age or each 1 mmHg (1 mmHg=0.133 kPa) increase in systolic blood pressure (SBP) would cause the risk of ADL disability to increase 9% or 1%, whose OR (95%CI) were separately 1.09 (1.06-1.12), 1.01 (1.00-1.02). Han nationality or cognitive impairment increased the risk of ADL disability, whose OR (95%CI) values were separately 4.90 (1.13-21.24), 2.47 (1.44-4.25), while increased lymphocyte count (>1.60×10⁹/L), being married, or participating in recreational activities decreased the risk of ADL disability, whose OR (95%CI) values were separately 0.51 (0.31-0.82), 0.52 (0.28-0.96), 0.43 (0.23-0.80). Conclusion In the elderly elevated lymphocyte count was associated with lower risk of ADL disability. In addition, incresed age, increased SBP, unmarried, Han nationality or cognitive impairment were associated with the increasing risk of ADL disability in older people, while participating in recreational activities would reduce the risk.

Objective: To investigate the influence factors of survival outcome among elderly aged ≥80 years old. Methods: In baseline survey in 2009, 930 participants aged ≥80 years old were enrolled from 7 longevity areas, to collect the information of socioeconomic factors, life style, cognitive function, activities of daily living and diseases, as well as physical examination to test biomarkers of blood and urine. The survival status was followed up at 2012 and 2014 survey. Stepwise Cox proportional hazards models were used to screen influence factors of 5-year survival. Results: During 5 years of follow-up, 571 participants died, 133 participants were lost to follow up, and the all-cause mortality was 63.4%. In stepwise Cox proportional hazards models, male, unmarried, self-reported poor life quality, disability in daily life, cognitive impairment, cardiovascular and cerebrovascular diseases, chronic kidney diseases were risk factors for elderly survival outcome, with the HR (95%CI) at 1.75 (1.40-2.12), 1.49 (1.10-2.03), 1.40 (1.16-1.69), 1.37 (1.11-1.70), 1.51 (1.22-1.88), 1.62 (1.18-2.23) and 1.48 (1.23-1.77) respectively. Each 1 year increase in age corresponded to 4% increase in mortality risk (HR (95%CI)=1.04 (1.02-1.05)); each 1 kg/m² increase in BMI corresponded to 5% increase in mortality risk (HR (95%CI)=0.95 (0.93-0.98)); each 1.0×10⁹/L increase in total lymphocyte count (TLC) corresponded to 13% increase in mortality risk (HR (95%CI)=0.87 (0.76-0.99)). Additionally, the mortality risk decreased 19% (HR (95%CI)=0.81 (0.66-0.98)) in participants with regularly physical exercise compared to those without; and the mortality risk decreased 41% (HR (95% CI)=0.59 (0.40-0.88)) in participants with elevated triglycerides (TG, ≥2.26 mmol/L) compared to those without. Conclusion In Chinese longevity areas, some nutritional and immune indices such as relatively higher level of BMI, TLC and TG were independent protective factors for 5-year survival outcome, which was different from general adults and younger elderly.

Objective:To seek any correlation between cortical activity and the swallowing of dysphagia patients with infratentorial stroke, and to observe any effect of three-needle acupuncture of the tongue on such activity.Methods:Thirty infratentorial stroke survivors with dysphagia were randomly divided into a tongue three-needle group and a sham acupuncture group, each of 15. Functional near-infrared spectroscopy was used to monitor changes in the concentration of oxygenated hemoglobin (ΔHbO 2) at rest, during acupuncture (or sham acupuncture), during real or sham electro-acupuncture, and at rest after the acupuncture or sham acupuncture treatment. The Modified Rankin Scale, a Penetration-Aspiration Scale (PAS), and the Functional Oral Intake Scale were employed to assess overall functional disability and the swallowing of both groups. Results:At rest the average ΔHbO 2 concentrations recorded in the left primary motor cortex, the left dorsolateral prefrontal cortex and the left premotor cortex in both groups were positively correlated with the PAS scores. During the acupuncture ΔHbO 2 concentration in the right inferior frontal gyrus and the left middle temporal gyrus increased significantly in the tongue three-needle group. It decreased significantly in the left somatosensory cortex and the left primary motor cortex. Conclusion:Three-needle acupuncture of the tongue induces changes in cortical activity in infratentorial stroke survivors with dysphagia, suggesting a potential technique for improving disordered swallowing.
