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.

BACKGROUND:As a common disease in middle-aged and elderly,osteoarthritis is difficult to cure,and the pathogenesis is not clear.Long non-coding RNA participates in the pathogenesis of osteoarthritis through many ways,such as regulating translation,promoting or inhibiting mRNA,and adsorbing miRNAs. OBJECTIVE:To review the types of common long non-coding RNA in osteoarthritis,and the influence of multiple long non-coding RNAs on the pathological factors related to osteoarthritis,to analyze the future application of long non-coding RNAs in osteoarthritis. METHODS:Literature retrieval was conducted in CNKI,WanFang Data,VIP database,PubMed,Web of Science and Sciencedirect databases,using the search terms of"osteoarthritis,degenerative joint disease,degenerative arthritis,OA,LncRNA,long non-coding RNA,long noncoding RNA,long intergenic non-coding RNA"in Chinese and English.All relevant literature published from 1976 and May 2024 was retrieved.After literature screening,induction,analysis and summary,93 articles were finally included for review. RESULTS AND CONCLUSION:This review collected 25 long non-coding RNAs that are well studied with osteoarthritis.Long non-coding RNAs,as a molecular sponge for miRNA,are competing endogenous RNAs to competitively adsorb miRNAs and then affect downstream targets.Long non-coding RNAs can regulate physiopathological processes such as chondrocyte apoptosis and proliferation,cartilage extracellular matrix degradation,and inflammatory responses.Long non-coding RNAs are expected to become a biomarker and potential therapeutic target for the clinical diagnosis and therapeutic prognosis of osteoarthritis,and it may become a new strategy for the clinical treatment of osteoarthritis in the future.

ObjectiveTo explore the effectiveness of traditional Chinese medicine (TCM) chronic disease management programme in preventing postoperative recurrence of colorectal polyps. MethodsThe clinical data of 447 postoperative colorectal polyp patients were retrospectively collected, and the patients were divided into an exposure group and a control group taking the acceptance of TCM chronic disease management programme as exposure factor, and the polyp recurrence rate as the main outcome indicator, comparing the differences in baseline characteristics, outcome events, and safety assessment between the two groups, and conducting correlation analysis between the length of medication and polyp recurrence. Multifactorial logistic regression was used to analyse the effects of receiving the TCM chronic disease management programme (TCM treatment and life management for spleen deficiency and dampness stasis syndrome, dampness and stasis obstruction in collaterals syndrome, and intestinal dampness and heat syndrome), gender, age, co-morbidities, TCM syndrome, and dietary and exercise factors on the outcome events. ResultsAmong 257 postoperative patients with colorectal polyps, there were 172 in the exposure group and 85 in control group. The recurrence rate of polyps in exposure group was 22.7% (39/172), while the recurrence rate in control group was 57.6% (49/85), and the difference between groups was statistically significant (P<0.01). The diameter of recurrent polyps in exposure group (median= 4.0 mm) was smaller than that in control group (median= 5.0 mm, P<0.01). The correlation analysis between the duration of medication taking and the recurrence of polyps in the spleen deficiency and dampness stasis syndrome group showed Phi value as -0.345 (P<0.001); the correlation analysis within the group of dampness and stasis obstruction in collaterals syndrome showed Phi value as -0.361 (P<0.05), indicating a negative correlation between the duration of medication taking and polyp recurrence. The results of multivariate logistic regression analysis indicated that the positive effect of accepting TCM chronic disease management programme on preventing polyp recurrence is statistically significant (OR=0.224, P<0.01). ConclusionAccepting TCM chronic disease management programme for colorectal polyps can help reducing the recurrence rate after polyp surgery, which is a protective factor for patients to the outcome event.

ObjectiveTo investigate the effects of Danhong injection on mitochondrial dynamics, morphology, and function in the rat model of chronic heart failure by mediating the adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK)/dynamin-related protein 1 (Drp1) pathway. MethodsFrom 75 SD rats, 15 rats were randomly selected as the sham group, and the remaining 60 rats were used to prepare a rat model of chronic heart failure by abdominal aortic constriction (AAC). The modeled rats were randomly allocated into model, Danhong Injection (6 mL·kg-1), and captopril (8.8 mg·kg-1) groups and administrated with corresponding agents for 15 consecutive days. The levels of N-terminal pro-brain natriuretic peptide (NT-pro BNP), adenosine diphosphate (ADP), adenosine triphosphate (ATP), interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α and the activities of mitochondrial respiratory chain complexes Ⅰ-Ⅳ were determined by enzyme-linked immunosorbent assay. The changes in cardiac function were detected by echocardiography. The ultrastructural changes of myocardial mitochondria were observed by transmission electron microscopy. Western blot was employed to assess the protein levels of AMPK, p-AMPK, Drp1, p-Drp1, optic atrophy 1 (Opa1), mitofusin (Mfn2), and fission l (Fis1) in the myocardial tissue. Real-time PCR was performed to determine the mRNA levels of Opa1, Mfn2, and Fis1, and immunohistochemistry to detect the expression of p-AMPK. ResultsCompared with the sham group, the model group showed elevated levels of NT-pro BNP, ADP, TNF-α, IL-6, and IL-1β (P<0.01), declined ATP level (P<0.01), weakened activities of mitochondrial respiratory chain complexes Ⅰ-Ⅳ (P<0.01), decreased left ventricular ejection fraction (LVEF) and left ventricular fraction shortening (LVFS) (P<0.01), and increased left ventricular internal diameter at end-diastole (LVDd) and leaf ventricular internal diameter at end-systole (LVIDs) (P<0.01). Electron microscopy results showed that the model group presented heavily abnormal myocardial structure, with large areas of myofilament structure destroyed and dissolved, significantly enlarged residual structural gaps, and fragmented mitochondria. Western blot results showed that the model group demonstrated down-regulated protein levels of p-AMPK, Mfn2, and Opa1 (P<0.01) and up-regulated protein levels of p-Drp1 and Fis1 (P<0.01) in the myocardial tissue. Real-time PCR results showed that the model group presented up-regulated mRNA level of Fis1 (P<0.01) and down-regulated mRNA levels of Mfn2 and Opa1 (P<0.01). Immunohistochemistry results showed reduced expression of p-AMPK in the model group compared with sham group (P<0.01). Compared with the model group, Danhong injection lowered the levels of NT-pro BNP, ADP, TNF-α, IL-6, and IL-1β (P<0.01), raised the level of ATP (P<0.01), increased the activities of mitochondrial respiratory chain complexes Ⅰ-Ⅳ (P<0.05, P<0.01), increased the LVEF and LVFS (P<0.01), decreased the LVDd and LVIDs (P<0.05, P<0.01), alleviated mitochondrial damage, up-regulated the protein levels of p-AMPK, Mfn2, and Opa1 (P<0.05, P<0.01), down-regulated the protein levels of p-Drp1 and Fis1 (P<0.01), reduced the mRNA level of Fis1 (P<0.01), elevated the mRNA levels of Mfn2 and Opa1 (P<0.05, P<0.01), and promoted the expression of p-AMPK (P<0.05). ConclusionDanhong injection repairs the imbalance of mitochondrial dynamics, restores the mitochondrial function, improves the myocardial energy metabolism, and reduces the inflammatory response by regulating the AMPK/Drp1 pathway, thus improving the cardiac function.

Objective:
To investigate the effects of plateau environment exposure on the reproductive system of male rats, so as to provide the reference for mechanisms of reproductive damage in plateau environment.
Methods:
Sixty SPF-grade 12-week-old male Wistar rats were randomly divided into the plain-exposed group, the 1 day-, 3 day-, 7 day-, 14 day- and 28 day- plateau-exposed groups. The rats in the plain-exposed group were raised under normal conditions for 28 days, while the rats in the plateau-exposed groups were raised in a simulated high-altitude plateau chamber. After the completion of the designated feeding periods, the rats were sacrificed under anesthesia, and testicular tissue and abdominal aortic blood were collected to detect the testicular index and evaluate sperm quality. Histological and cellular morphologies of the testicular tissue were analyzed. Additionally, the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and reactive oxygen (ROS) in the testicular tissue were determined, along with serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T).
Conclusions
Plateau environment may cause a decrease in testicular index and sperm quality, impair mitochondrial function, induce oxidative stress, and thus affect reproductive system of male rats. However, there are signs of self-repair in the reproductive system with the increase of exposure duration.

The clinical practice guidelines of traditional Chinese medicine (TCM) have problems such as limited clinical application and unclear implementation effects, which may be related to the lack of clinical practice evidence. To provide reliable and precise evidence for clinical practice, this article proposes a model of combining TCM guidelines with real-world study, which includes 4 steps. Firstly, during the implementation process of the guidelines, a high-quality research database is established. Secondly, the recommendations in the guidelines are evaluated based on the established database in multiple dimensions, including applicability, effectiveness, safety, and cost-effectiveness, and thus their effectiveness in practical applications can be determined. Thirdly, based on the established database, core prescriptions are identified, and the targeted populations and medication plans are determined. That is, the best treatment regimen is established based on the analysis of abundant clinical data regarding the effects of different medication frequencies, dosages, and duration on efficacy. Fourthly, the guidelines are updated according to the real-world evidence. The research based on this model can provide real-world evidence for ancient and empirical prescriptions, improving their application in clinical practice. Moreover, this model can reduce research costs and improve research efficiency. When applying this model, researchers need to pay attention to the quality of real-world evidence, ensuring that it can truly reflect the situation in clinical practice. In addition, importance should be attached to the clinical application of guideline recommendations, ensuring that doctors can conduct standardized diagnosis and treatment according to the guidelines. Finally, full-process participation of multidisciplinary experts is encouraged to ensure the comprehensiveness and scientificity of the study. In conclusion, the application of this model will contribute to the development of TCM guidelines responsive to the needs of clinical practice and achieve the goal of promoting the homogenization of TCM clinical diagnosis and treatment.

The classification of traditional Chinese medicine (TCM) syndromes is one of the core technical elements in the industry standard of Specification of Diagnosis and Therapeutic Effect Evaluation of Diseases and Syndromes in TCM. In the past,when clinical standards for TCM were formulated,the determination of TCM syndrome classification relied heavily on textbooks and expert experience,lacking systematic research. This approach thus failed to reflect the advancement and scientificity of the standards,thereby affecting their implementation and application. This article reviewed the presentation forms and technical methods of TCM syndrome classification,including the two-tier syndrome classification model with primary and secondary symptoms,as well as the application of modern literature research,ancient literature research,Delphi method,in-depth expert interviews,consensus conferences,and real-world research. When syndrome classification standards are developed,it is necessary to build upon modern literature research,adopt a mixed approach combining qualitative research and quantitative analysis results,and reach expert consensus through consensus conferences. Through systematic research,the scientificity,applicability,and coordination of TCM syndrome classification standards can be enhanced,providing guidance for the standardization of TCM.

BACKGROUND:Studies have shown that imbalance of bone metabolism during glucocorticoid-induced osteonecrosis of the femoral head necrosis is closely related to oxidative stress. OBJECTIVE:To investigate the pathological mechanism by which oxidative stress-induced ferroptosis promote apoptosis in osteoblasts involved in steroid-induced osteonecrosis of the femoral head. METHODS:General data and serum specimens were collected from 47 patients with steroid-induced osteonecrosis of the femoral head.In addition,six femoral head specimens were collected from these patients.According to the Association Research Circulation Osseous(ARCO)staging system,serum specimens were grouped into ARCO Ⅱ,Ⅲ,and IV,while femoral head specimens were classified into ARCO Ⅲ and IV.Serum levels of malondialdehyde and superoxide dismutase 1 were measured.The protein expression of superoxide dismutase 1,glutathione peroxidase 4,Bcl-2 in the femoral head was detected and verified by Data independent acquisition(DIA)for quantitative sequencing,western blot and alkaline phosphate detection. RESULTS AND CONCLUSION:The ARCO stage of patients with steroid-induced osteonecrosis of the femoral head was independent of age,sex and necrotic side.The serum levels of malondialdehyde and superoxide dismutase 1 were higher in patients with ARCO stage Ⅲ compared with those with ARCO stage Ⅱ and IV.The results of DIA protein quantification showed that the function of differential proteins was mainly related to redox.The levels of superoxide dismutase 1,glutathione peroxidase 4,and Bcl-2 in the necrotic region were lower than in the normal region,as well as lower in ARCO stage IV than in ARCO stage Ⅲ.Western blot verified the results of DIA protein quantification.The alkaline phosphatase activity was lower in the necrotic region than in the normal region,as well as lower in ARCO stage IV than in ARCO stage Ⅲ.In the necrotic and sclerotic regions,the function of differential proteins was also related to redox,and superoxide dismutase 1,glutathione peroxidase 4,Bcl-2 protein expression and alkaline phosphatase activity were lower in the necrotic area than in the sclerotic region,as well as lower in ARCO stage IV than in ARCO stage Ⅲ.To conclude,glucocorticoids can influence the progression of steroid-induced osteonecrosis of the femoral head by upregulating oxidative stress levels,inducing osteoblast ferroptosis,and inhibiting osteogenic function.
