Objective: To observe the effect of Mo-Rubbing abdomen manipulation on glucose metabolism and inflammatory factors in rats with type 2 diabetes mellitus (T2DM). Methods: Sixty Sprague-Dawley rats were randomly divided into a normal group (n=10) and a group for modeling (n=50) using the random number table method. Rats in the group for modeling were induced to form T2DM models by a high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin. Thirty successfully modeled rats were randomly divided into a model group, a Mo-Rubbing abdomen group, and a metformin group, with 10 rats in each group. Rats in the normal group and the model group received no intervention, those in the Mo-Rubbing abdomen group received Mo-Rubbing abdomen manipulation, and those in the metformin group received metformin by gavage. After 8-week intervention, fasting insulin (FINS), fasting plasma glucose (FPG), homeostasis model assessment for insulin resistance (HOMA-IR) and area under the curve at the oral glucose tolerance test (AUC-OGTT), as well as serum inflammatory factors interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α were detected, and the morphological changes of the pancreas were also observed. Results: After the 8-week intervention, the levels of FINS, FPG, HOMA-IR, and AUC-OGTT of rats in the Mo-Rubbing abdomen group were significantly lower than those in the model group (P<0.05); the pancreatic injury degree in the Mo-Rubbing abdomen group and the metformin group was lower than that in the model group. Compared with the model group, the serum IL-1β, IL-6, and TNF-α levels of rats in the Mo-Rubbing abdomen group were significantly decreased (P<0.05), and the serum IL-1β and TNF-α levels of the metformin group showed a downward trend; the serum IL-6 and TNF-α levels in the Mo-Rubbing abdomen group were significantly lower than those in the metformin group (P<0.01). There was a significant positive correlation between FPG with IL-1β, IL-6, and TNF-α in the T2DM rats (P<0.01). Conclusion: Mo-Rubbing abdomen manipulation reduces the inflammatory response and improves the morphological changes of the pancreas in T2DM rats, thereby achieving the effect of lowering blood glucose.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.
