ObjectiveThis study aims to investigate the dynamic changes in general body parameters, blood glucose, and blood lipid profiles in obese cynomolgus monkeys, exploring the correlations among these parameters and providing a reference for research on the obese cynomolgus monkey model. Methods30 normal male cynomolgus monkeys aged 5 - 17 years old (with body mass index < 35 kg/m² and glycated hemoglobin content < 4.50%) and 99 spontaneously obese male cynomolgus monkeys (with body mass index ≥35 kg/m² and glycated hemoglobin content < 4.50%) were selected. Over a period of three years, their abdominal circumference, skinfold thickness, body weight, body mass index, fasting blood glucose, glycated hemoglobin, and four blood lipid indicators were monitored. The correlations between each indicator were analyzed using repeated measurement ANOVA, simple linear regression, and multiple linear regression correlation analysis method. Results Compared to the control group, the obese group exhibited significantly higher levels of abdominal circumference, skinfold thickness, body weight, body mass index, and triglyceride (P＜0.05). In the control group, skinfold thickness increased annually, while other indicators remained stable. Compared with the first year, the obese group showed significantly increased abdominal circumference, skinfold thickness, body weight, body mass index, triglyceride, and fasting blood glucose in the second year(P＜0.05), with this increasing trend persisting in the third year (P＜0.05). In the control group, the obesity incidence rates in the second and third years were 16.67% and 23.33%, respectively, while the prevalence of diabetes remained at 16.67%. In the obese group, the diabetes incidence rates were 29.29% and 44.44% in years 2 and 3, respectively. Among the 11-13 year age group, the incidence rates were 36.36% and 44.68%, while for the group older than 13 years, the rates were 28.13% and 51.35%. Correlation analysis revealed significant associations (P＜0.05) between fasting blood glucose and age, abdominal circumference, skinfold thickness, body weight, and triglyceride in the diabetic monkeys. Conclusion Long-term obesity can lead to the increases in general physical indicators and fasting blood glucose levels in cynomolgus monkeys, and an increase in the incidence of diabetes. In diabetic cynomolgus monkeys caused by obesity, there is a high correlation between their fasting blood glucose and age, weight, abdominal circumference, skinfold thickness, and triglyceride levels, which is of some significance for predicting the occurrence of spontaneous diabetes.

Objective To explore the characteristics of Xin'an doctors in the syndrome differentiation and treatment of liver cirrhosis from the dimensions of symptoms,syndromes and medication using data mining methods.Methods Medical cases and prescriptions for liver cirrhosis were collected from Xin'an medical literature.Data mining was performed using frequency analysis,complex network analysis,Louvain clustering analysis and factor analysis to investigate syndromes,symptoms,and medicines.Results A total of 363 prescriptions were analyzed,involving 15 syndromes and 325 kinds of Chinese materia medica,with 33 identified as core medications.Tonifying herbs were the most frequently used;the primary syndromes were liver qi stagnation and water retention;core symptoms of liver qi stagnation included emotional distress,reduced appetite and hypochondriac pain,with core medications such as Bupleuri Radix and Poria;core symptoms of water retention included lower limb edema and abdominal distension,with core medications such as Pinelliae Rhizoma,Citri Reticulatae Pericarpium,Magnoliae Officinalis Cortex and Poria.Factor analysis of core medications identified 12 common factors.Conclusion The pathogenesis of liver cirrhosis involves deficiency in nature and excess in superficiality,primarily affecting the liver and closely related to the spleen and kidneys.Xin'an doctors emphasize treating the symptoms with qi-regulating,blood-activating,dampness-drying and heat-clearing strategies,while simultaneously addressing the root with qi-tonifying,spleen-strengthening,liver-nourishing and kidney-replenishing therapies.

Objective To explore the regulatory role of N-methyl berbamine(N-MB)in intracellular calcium homeostasis in H9c2 car-diomyocytes,and,thereby,clarify the possible mechanism of the myocardial protective effect of N-MB.Methods Binding of N-MB to CaV1.2 channels was simulated using the MOE software,and the binding affinity and binding mode were determined.The hCaV1.2 gene was transfected into HEK293 cells,and the effect of N-MB(30 μmol/L)on the CaV1.2 current was detected using the whole-cell patch clamp technique.In addition,a Fluo 3-AM fluorescent probe was loaded into H9c2 cardiomyocytes,and the effect of N-MB(3,30 μmol/L)on intracellular calcium ion concentration was observed under a laser confocal microscope.The effect of N-MB(3,30 μmol/L)on the expression of Ca2+regulation-related genes Cacna1c,Cacnb2,Ryr2,Serca2a,and Ncx1 in H9c2 cardiomyocytes was examined using real-time quantitative PCR.Results N-MB was predicted to bind to CaV1.2 channels.The binding sites mainly involved Phe1191,Thr1420,and Asn771,and the binding modes were H-donor,pi-pi,and pi-H.N-MB(30 μmol/L)significantly inhibited CaV1.2 currents,with an inhibition rate of 76.09％±7.41％.The fluorescence intensity of intracellular Ca2+level in H9c2 cardiomyocytes was significantly enhanced with N-MB treatment(3,30 μmol/L,P＜0.01).Compared with the control group,differences in the expression of Cacna1c,Serca2a,and Ncx1 in H9c2 cardiomyocytes were not significant after N-MB(3,30 μmol/L)intervention(P＞0.05),whereas the expression of Cacnb2 significantly reduced(P＜0.001)and the expression of Ryr2 significantly increased(P＜0.05).Conclusion N-MB binds to CaV1.2 calcium channels.N-MB may regulate intracellular calcium homeostasis by inhibiting calcium currents by decreasing the gene expression of CaV1.2 calcium channels.Additionally,N-MB may also increase intracellular Ca2+concentration by promoting the expression of Ryr2,which could be the mechanism underlying the myocardial protective effect of N-MB.

Objective:Postdoctoral researchers in Chinese universities commonly face a high risk of mental health issues,such as depression,yet the underlying causes and mechanisms remain unclear.This study aims to explore the influence of childhood socioeconomic status(SES)on depression among postdoctoral researchers and the mediating roles of current subjective SES and perceived stress in this process. Methods:An online survey was conducted among postdoctoral researchers at a university.The survey included a general information questionnaire,the Childhood Socioeconomic Status Scale,the Subjective Socioeconomic Status Scale,the Perceived Stress Scale,and the Patient Health Questionnaire.A total of 505 valid responses were collected.Pearson correlation analysis was used to analyze the data,and the PROCESS macro was employed for chain mediation analysis. Results:Childhood SES was significantly positively correlated with current subjective SES(P<0.05)and significantly negatively correlated with postdoctoral tenure,perceived stress,and depression(all P<0.05).Current subjective SES was significantly negatively correlated with perceived stress and depression(both P<0.05),while perceived stress was significantly positively correlated with depression(P<0.05).The chain mediation effect of childhood SES → current subjective SES → perceived stress → depression was significant(P<0.05). Conclusion:Childhood socioeconomic status can influence depression among postdoctoral researchers through the mediating roles of current subjective socioeconomic status and perceived stress.These findings provide a target for the prevention and intervention of depression in postdoctoral populations and offer a reference for the development of mental health promotion strategies for young university faculty.
