Exploration on interaction of Chinese and Western drugs / 中国中西医结合杂志

To study the interaction of traditional Chinese medicines and Western drugs in the interest of the interaction of Chinese and Western drugs viewing from their own characteristics, pharmacokinetics and pharmacodynamics to provide a scientific basis for rational clinical utilization of drugs. Pharmacological mutual coordination and/or restriction existed between the two kinds of drugs. When they were used in combination, it would increase or decrease adverse reactions, or even toxic reaction. When traditional Chinese drugs were used in combined with Western drugs, it is ought to know the nature and pharmacological effect of various chemical constituents in the compound for the best combination, try to avoid adverse drug interactions for the sake of reaching the goal of high effectiveness, safety and harmlessness.

Beta-cell dysfunction is the primary contributor to the early postpartum diabetes among Chinese women with history of gestational diabetes mellitus / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Women with a history of gestational diabetes mellitus (GDM) are at higher risk of future development of diabetes. This study investigated the risk factors associated with early postpartum abnormal glucose regulation (AGR) among Chinese women with a history of GDM.</p><p><b>METHODS</b>A total of 186 women with a history of GDM were screened for early postpartum AGR at 6-8 weeks after delivery. Those with AGR were given lifestyle intervention therapy and reevaluated in 6-12 months. The demographic, anthropometric, prenatal and delivery data were recorded. The plasma high-sensitivity C-reactive protein (HsCRP) and lipid concentration were measured, and insulin secretion were analyzed. Insulinogenic index Deltains30'/DeltaBG30', the homeostasis model assessment index (HOMA)-B, and HOMA-IR were calculated. Multiple regression analysis was performed to identify the risk factors.</p><p><b>RESULTS</b>Of the GDM women 28.0% (52/186) had AGR at 6-8 weeks after delivery; 45.2% (17/40) of these AGR women reminded abnormal after 6-12 month lifestyle intervention. Compared to the women who reverted to normal, women with consistent AGR showed significantly lower fasting insulin concentration, lower Deltains30'/DeltaBG30' as well as lower HOMA-B. No significant differences in age, body mass index (BMI), waist circumference, blood pressure, lipid level, HsCRP and HOMA-IR were observed between the two groups. Pre-pregnancy BMI = 25 kg/m(2), fasting glucose level = 5.6 mmol/L and/or 75 g oral glucose tolerance test (OGTT) 2 hours glucose level = 11.1 mmol/L during pregnancy were predictors for the AGR at 6-8 weeks after delivery. Deltains30'/DeltaBG30 = 1.05 was a significant risk contributor to the consistent early postpartum AGR.</p><p><b>CONCLUSION</b>There is a high incidence of early postpartum AGR among Chinese woman with prior GDM. Beta-cell dysfunction, rather than insulin resistance or inflammation, is the predominant contributor to the early onset and consistent AGR after delivery.</p>
