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.

PURPOSE: Synuclein-gamma (SNCG), which was initially identified as breast cancer specific gene 1, is highly expressed in advanced breast cancers, but not in normal or benign breast tissue. This study aimed to evaluate the effects of SNCG siRNA-treatment on breast cancer cells and elucidate the associated mechanisms. METHODS: Vectors containing SNCG and negative control (NC) siRNAs were transfected into MDA-MB-231 cells; mRNA levels were determined by real-time polymerase chain reaction. Cell proliferation was evaluated using the MTT assay, cell migration was assessed by the Transwell assay, apoptosis and cell cycle analyses were conducted with the flow cytometer, and Western blot analysis was performed to determine the relative levels of AKT, ERK, p-AKT, and p-ERK expression. RESULTS: SNCG mRNA levels were significantly reduced in MDA-MB-231 cells transfected with SNCG siRNA. Our results indicate that in SNCG siRNA-treated cells, cell migration and proliferation decreased significantly, apoptosis was induced, and the cell cycle was arrested. Western blot analysis indicated that the protein levels of p-AKT and p-ERK were much lower in the SNCG siRNA-treated groups, than in the control and NC groups. CONCLUSION: SNCG siRNA could decrease the migration and proliferation of breast cancer cells by downregulating the phosphorylation of AKT and ERK.

Objective To analyze the magnetic resonance images (MRI) of patients with spinal epidural lipomatosis (SEL) in high-altitude areas and to determine the optimal cut-off value for diagnosis with epidural fat thickness. Methods This retrospective study included patients who underwent lumbosacral MRI examination for lumbosacral pain in Ping’an District Hospital of Traditional Chinese Medicine, Haidong City, China from January 1, 2021 to December 31, 2022. The epidural fat thickness in vertebral segments T12/L1 to L5/S1 was compared between the SEL group and the non-SEL group. The diagnostic efficacy with different cut-off values at each vertebral segment was evaluated. Between-group comparisons were performed using the t-test, Mann-Whitney U test, chi-square test, or modified chi-square test. The area under the receiver operating characteristic (AUC) was used to evaluate the diagnostic efficiency. The DeLong test was used to compare AUC between the two groups. Results A total of 370 patients were included (60 in the SEL group and 310 in the non-SEL group). There were no significant differences in age, sex, height, body weight, and body mass index between the two groups (all P > 0.05). At different vertebral segments, the epidural fat thickness was significantly higher in the SEL group than in the non-SEL group (all P < 0.05). The cut-off values for SEL diagnosis with epidural fat thickness in segments T12/L1 to L5/S1 were 2.23, 4.25, 4.85, 5.57, 7.21, and 8 mm, respectively. The AUC of MRI SEL diagnosis with epidural fat thickness in segment L5/S1 was the highest (0.945, 95% confidence interval [CI]: 0.916-0.966, P < 0.001). SEL diagnosis with epidural fat thickness > 8 mm in segment L5/S1 was the most accurate, with an AUC of 0.931 (95% CI: 0.901-0.955, P < 0.001), a sensitivity of 95.0%, and a specificity of 91.3%; this AUC was significantly higher than those of diagnosis with other cut-off values (all P < 0.05). Conclusion SEL patients have significantly increased epidural fat in the spinal canal. Epidural fat thickness > 8 mm in segment L5/S1 can be used for diagnosis of SEL with improved efficiency and accuracy.

ObjectiveTaking the rat model of spleen-stomach damp-heat syndrome(SSDHS) as the research object, this study aimed to investigate the potential biomarkers of SSDHS and the related metabolic pathways based on urine metabolomics, and tried to reveal the essence of SSDHS at the level of endogenous small molecular metabolites. MethodSixteen SD rats were randomly divided into normal and model groups. The normal group was fed normal chow and the model group was fed with 200 g·L-1 honey water daily, and lard and Chinese Baijiu alternately on alternate days for 17 days. The SSDHS model rats were exposed to external dampness-heat environment with temperature at 30-34 ℃, relative humidity of 95% for 2 h at the same time every day from the 10th day for 7 d. Then, the model was evaluated by observing the general conditions of the rats, measuring the contents of motilin(MTL) and gastrin(GT) in plasma by enzyme-linked immunosorbent assay(ELISA), and examining the histopathology of gastronitestinal tissues. In additon, the urine metabolomics analysis was performed by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS), and the detection conditions was as follows:ACQUITY™ UPLC BEH C18 column(2.1 mm×100 mm, 1.7 μm), mobile phase of 0.1% formic acid aqueous solution(A)-0.1% formic acid acetonitrile solution(B) for gradient elution (0-3 min, 1%-18%B; 3-8 min, 18%-40%B; 8-10 min, 40%-100%B), the flow rate of 0.4 mL·min-1, electrospray ionization(ESI) in positive and negative ion modes, scanning range of m/z 50-1 000. The univariate and multivariate statistical analysis were constructed for screening inter-group differential ions, the element composition was calculated according to the precise relative molecular weight, and ion information was matched with databases such as Human Metabolome Database(HMDB) to identify biomarkers. Kyoto Encyclopedia of Genes and Genomes(KEGG) database was used to obtain the biological information of metabolites, and their associated metabolic pathways were analyzed by MetaboAnalyst 5.0. ResultCompared with the normal group, the rectal temperature of the model group increased significantly(P<0.01), the levels of plasma MTL and GT decreased significantly(P<0.05, P<0.01), and pathological changes such as bleeding, congestion and inflammatory infiltration in the gastric and colonic tissues. A total of 25 differential metabolites such as L-histidine, citric acid and isocitric acid were found to be the potential biomarker of SSDHS by urine metabolomics, 13 of which were phase Ⅱ metabolites of endogenous substances(glucuronic acid conjugates, sulfuric acid conjugates and acetyl conjugates), involving the metabolic pathways of histidine metabolism, tricarboxylic acid cycle, glyoxylate and dicarboxylate metabolism. ConclusionSSDHS primarily causes disorders of histidine metabolism, tricarboxylic acid cycle, glyoxylate and dicarboxylate metabolism, as well as the imbalance of the activation/inactivation of endogenous metabolites, which may involve the immune response, material and energy metabolism, inflammatory response and intestinal flora, and may provide a basis for the establishment and application of SSDHS model.
