Lifestyle intervention for 6 years in IGT was associated with a 47% reduction in the incidence of severe, vision-threatening retinopathy over a 20 year interval, primarily due to the reduced incidence of diabetes in the intervention group. However, similar benefits were not seen for nephropathy or neuropathy.
The aim of this work was to study the relationship between excess body weight and the risks of hypertension and diabetes in the population of northeastern China. Subsections of a cross-sectional survey in Da Qing City were used to assess the relationship of excess weight to risk factors for coronary heart disease (CHD). A 6-year prospective study also assessed the probability of developing Type 2 diabetes. A total of 2856 adults (25-70 years of age) were assessed cross-sectionally and 629 non-diabetic subjects of similar age were followed-up for 6 years. Blood pressure, plasma fasting glucose, triglycerides, high-density lipoporotein (HDL) cholesterol and fibrinogen levels were measured as well as weight, height and waist and hip circumferences. About 45% of adults had a body mass index (BMI) of > or =25.0. Risk factors increased with increasing BMI from a baseline value of 21.0: at a BMI of 23.0-24.9, the risk of hypertension and hypertriglyceridaemia doubled; the risk increased threefold at a BMI of 25.0-26.9. The prevalence of Type 2 diabetes increased progressively in women within the normal BMI range and in men from a BMI of 25.0. Type 2 diabetes was four times as common if the BMI was >27.0. Increasing waist measurements predicted 10-fold increases in hypertension and a three-to-five times increased risk of diabetes. Suitable waist cut-off points were 85cm for men and 80cm for women, with statistical analysis showing waist as the more dominant predictor of risk than age, waist-to-hip ratios or BMIs. Hence, small increases in BMI, and particularly in waist circumference, predict a substantial increase in the risk of diabetes and risk for CHD, especially hypertension, in Chinese adults.
Both live attenuated (HA-L) and inactivated (HA-I) hepatitis A vaccine were licensed for routine use in China. Although phase 1, 2 and 3 clinical studies of both vaccines have been completed, further systematic evaluation of their immunogenicity and immunological persistence under phase 4 clinical studies in a wide range of conditions and involving large populations is necessary. A phase IV clinical trial (NCT02601040) was performed in 9000 participants over 18 months of age. Geometric mean concentrations (GMCs) and seroconversion rates (SRs) were compared at five time points during 3 years for 1800 individuals among them. The SRs of HA-L and HA-I were 98.08% (95% CI 95.59%e99.38%) and 99.64% (95% CI 98.93%e100.00%) respectively 28 days after administration of the first dose, and remained at 97.07% (95% CI 94.31%e98.73%) or above and 96.73% (95% CI 94.07%e98.42%) or above respectively during the following 3 years. The GMCs for both the HA-L and HA-I groups showed that both vaccines elicited high anti-HAV titres, considerably more than the threshold of protection needed against HAV infection in humans, and these titres were sustained. Hence, both HA-I and HA-L vaccines could provide an excellent long-term protective effect, and supported the routine use of both vaccines.
Aim
To compare the 2-h postprandial blood glucose (PPBG) excursion following a standard test meal in insulin-requiring patients with diabetes treated twice daily with human insulin mix 50 vs. insulin lispro mix 50 (LM50).
Methods
This was a multicentre, randomised, open-label, crossover comparison of two insulin treatments for two 12-week treatment periods in 120 Chinese patients. One- and 2-h PPBG and excursion values were obtained following a standardised test meal. Fasting blood glucose (FBG), haemoglobin A1c (HbA1c), insulin dose, rate of hypoglycaemia and safety data were obtained. A crossover analysis using SAS Proc MIXED was employed.
Results
Mean 2-h PPBG excursion decreased from 6.32 ± 3.07 mmol/l at baseline to 3.47 ± 2.97 mmol/l at end-point in the LM50 group, and from 6.31 ± 2.88 at baseline to 5.02 ± 3.32 mmol/l at end-point in the human insulin mix 50 group (p < 0.001). Two-hour PPBG (p = 0.004) and 1-h PPBG excursion (p < 0.001) were significantly lower with LM50 as compared with human insulin mix 50. Both treatment groups were equivalent for HbA1c control, 1-h PPBG and insulin dose requirements. Mean FBG was higher with LM50 than with human insulin mix 50 (p = 0.023). The overall incidence of treatment-emergent adverse events and hypoglycaemia rate per 30 days were similar between treatment groups.
Conclusions
Insulin lispro mix 50 provided better postprandial glycaemic control compared with human insulin mix 50 while providing the convenience of injecting immediately before meals. Both treatments were generally well tolerated by all randomly assigned patients.
Background. To assess the association of metformin monotherapy with the risk of all-cause deaths and cardiovascular deaths and events in type 2 diabetes patients in real clinical practice. Methods. This retrospective, observational study comprised patients with type 2 diabetes initially treated with metformin or nonmetformin monotherapy over 2011-2016. Data were extracted from the National Healthcare Big Data database in Fuzhou, China. Propensity score matching (PSM) was performed, matching each patient on metformin to one on nonmetformin in terms of a set of covariates. The primary endpoint was all-cause death, and secondary endpoints were cardiovascular death, heart failure, and heart failure hospitalization. Covariate-adjusted associations of metformin use with all the endpoints were assessed by Cox proportional hazards models. Results. Among 24,099 patients, 5491 were initially treated with metformin and 18,608 with nonmetformin. PSM yielded 5482 patients in each cohort. During a median follow-up of 2.02 years, we observed 110 and 211 deaths in the metformin and nonmetformin groups, respectively. Metformin was significantly associated with reduced risk of all-cause death (adjusted hazard ratio (aHR) 0.52, 95% confidence interval (CI) 0.39-0.69), cardiovascular death (aHR 0.63, 95% CI 0.43-0.91), and heart failure (aHR 0.61, 95% CI 0.52-0.73), whereas the reduced risk in heart failure hospitalization was not statistically significant (aHR 0.70, 95% CI 0.47-1.02). Conclusions. In this analysis of electronic health record data from a large database in China, metformin as first-line monotherapy greatly reduced the risk of all-cause death, cardiovascular death, and heart failure in diabetes patients as compared with nonmetformin medications.
Background
Limited information is available on the long‐term risk of cardiovascular disease (CVD) associated with hypertriglyceridaemia (HTG) in the Chinese population. We estimated this risk over a 23‐year period in participants recruited from among those included in the Da Qing Diabetes Study.
Methods
A total of 833 Chinese adults including 379 with normal glucose levels and 454 with hyperglycaemia were identified by their oral glucose tolerance in 1986 in Da Qing, China. CVD outcomes were monitored until 2009. Thirty‐four percent (280/833) of the participants had HTG, which was defined as a fasting plasma triglyceride (TG) level ≥ 1.7 mmol/L, at the baseline time point.
Results
Over the 23‐yearfollow‐up period, 149 subjects in the HTG group and 190 subjects in the non‐HTG group (NTG group) experienced their first CVD event, including fatal or nonfatal myocardial infarction (MI) and stroke. The age and sex‐adjusted annual incidence of the first CVD event per 1000 person‐years was 30.23 for the HTG group vs 18.68 for the NTG group. The corresponding rates for MI and stroke were 7.71 vs 3.89 and 19.55 vs 13.98, respectively. After adjusting for confounders, the HTG group had a 28% higher risk of the first CVD event than the NTG group. This association was significant among only the subjects with a serum cholesterol level > 5.7 mmol/L and those with diabetes or impaired glucose tolerance (IGT).
Conclusion
HGT predicted a substantially higher subsequent long‐term risk of the first CVD event in Chinese adults, especially in those with hypercholesterolaemia and hyperglycaemia.
Amomum villosum (Zingiberaceae) grows as a perennial herb in (Sarbajna, 1990). Additionally, P. costina was isolated as an endophyte from leaves of Amomum siamense and Alpinia malaccensis in Thailand (Bussaban et al. 2003). This is the first report of P. costina causing a leaf lesion on A. villosum in China.
