"Sinew prescription correspondence" is the principle of selecting prescriptions for channel sinew diseases. On the basis of the theory of syndrome differentiation and treatment, the pulse manifestation corresponds to the channel sinew syndrome, which can improve the flexibility and standardization of clinical prescriptions. From the perspective of systematic dialectical sphygmology, this paper explains the dialectical relationship between channel sinew theory and pulse body elements, pulse wall elements, pulse elements and blood flow elements, and clarifies the internal relationship between pulse manifestation and prescriptions at the level of channel sinew disease. The prescription is derived from the method, while the method is established with the syndrome, and the prescription is unified by the method. According to the theory of "sinew prescription correspondence", the treatment ideas of channel sinew diseases were analyzed from the perspective of channel sinew distribution, functional characteristics and structural changes. On this basis, the diagnosis of channel sinew disease and the application of prescriptions are expanded, and the research on the internal treatment and diagnosis mode of "pulse manifestation-channel sinew-zang fu (脏腑)" is prospected, so as to expand the differentiation and treatment methods of channel sinew theory.

ObjectiveTo analyze the comorbidity patterns of chronic metabolic diseases and their influencing factors among residents aged 35‒75 years old in Nantong City of Jiangsu Province, and to provide theoretical support for the prevention and control of comorbidities. MethodsThe permanent residents aged 35‒75 years from the Comprehensive Prevention and Control Project of Cardiovascular and Cerebrovascular Diseases in Nantong City from 2021 to 2024 were selected as the research subjects. Clustering analysis and association rule were used to investigate the comorbidity patterns of chronic metabolic diseases, and their influencing factors were identified through logistic regression analyses. ResultsThe prevalence of comorbidity of chronic metabolic diseases among residents aged 35‒75 years in Nantong City was 47.40%. Among comorbidity patterns based on disease counts, the prevalence of hypertension+dyslipidemia was highest in binary comorbidity patterns (6.25%), while that of hypertension+dyslipidemia+obesity was highest in ternary comorbidity patterns (4.01%). Association rules showed that in both binary and ternary comorbidity patterns, the confidence level was highest for obesity+hypertension (72.70%) and obesity+dyslipidemia+hypertension (74.54%). Renal insufficiency formed an independent cluster in cluster analyses. Logistic regression analyses revealed that, compared with the non-comorbidity group, males (OR=2.22, 95%CI: 1.69‒2.91), advanced age (45‒54 years, OR=1.38, 95%CI: 1.02‒1.88; 55‒64 years, OR=1.59, 95%CI: 1.14‒2.23; 65‒75 years, OR=2.34, 95%CI: 1.58‒3.47), and low physical activity (OR=1.26, 95%CI: 1.10‒1.65) were influencing factors for metabolic disease comorbidity. ConclusionIn the comorbidity patterns of chronic metabolic diseases among residents aged 35‒75 years in Nantong City, hypertension, diabetes mellitus, and dyslipidemia interact with each other. Individuals with obesity are more prone to diseases such as hypertension and dyslipidemia. Prevention and control of chronic metabolic diseases should be strengthened for males, individuals with low physical activity and advanced age.

Objective To assess the nutritional status of patients undergoing preventive ileostomy and identify the factors that influence the status,thereby providing guidance for medical staff to formulate nutritional intervention strategies.Methods Convenient sampling was used to select 239 patients undergoing preventive ileostomy who were attending follow-up visits or hospitalized while awaiting stoma closure at 4 tertiary hospitals in Guangzhou from November 2023 to July 2024.Data was collected by a general information questionnaire and the Patient-Generated Subjective Global Assessment tool.Factors influencing nutritional status were analyzed by multivariable ordinal Logistic regression.Results Of the 239 patients,227 provided valid responses.The nutritional status was categorized as follows:64 patients(28.19%)had good nutrition or were at risk of malnutrition;104(45.81%)exhibited moderate malnutrition;59(25.99%)had severe malnutrition.Multivariable ordinal Logistic regression analysis revealed that preoperative cumulative chemotherapy cycles,postoperative duration,age,current dietaiy type,use of oral nutritional supplements(ONS),enterostomy-related complications,and stoma self-care ability were significant predictors of nutritional status(P<0.05).Conclusion Patients undergoing preventive ileostomy are at a high risk of moderate to severe malnutrition and ONS provided to patients did not result in a meaningful improvement in their nutritional health.Specifically,those patients with a higher number of cumulative preoperative chemotherapy cycles,shorter postoperative recovery time,aged ≥ 65 years,liquid diet or semi-liquid diet,experiencing enterostomy-related complications,or poor stoma self-care ability,are particularly vulnerable to malnutrition.These findings underscore the need for medical staff to formulate intervention strategies based on these factors to improve nutritional status of patients undergoing preventive ileostomy.

proteins in quadriceps muscle tissue of the rats in model group were significantly decreased(P<0.05);compared with model group,the expression levels of IL-6,JAK,STAT3,Pax7,Desmin,Myosin,and Myogenin proteins in quadriceps muscle tissue of the rats in celecoxib group and acupuncture group were significantly increased(P<0.05);compared with celecoxib group,the expression levels of IL-6,JAK,STAT3,Pax7,Desmin,Myosin,and Myogenin proteins in quadriceps muscle tissue of the rats in acupuncture group were significantly increased(P<0.05).Compared with control group,the expression levels of B-cell lymphoma 2(Bcl-2),B-cell lymphoma-xl(Bcl-xl),and myeloid cell leukemia 1(MCL1)proteins in quadriceps muscle tissue in model group were significantly decreased(P<0.05),and the expression levels of Bcl-2-associated X protein(Bax)and cysteinyl aspartate specific proteinase-3(Caspase-3)proteins were significantly increased(P<0.05);compared with model group,the expression levels of Bcl-2,Bcl-xl,and MCL1 proteins in quadriceps muscle tissue of the rats in celecoxib group and acupuncture group were significantly increased(P<0.05),and the expression levels of Bax and Caspase-3 proteins were significantly decreased(P<0.05);compared with celecoxib group,the expression levels of Bcl-2,Bcl-xl,and MCL1 proteins in quadriceps muscle tissue of the rats in acupuncture group were significantly increased(P<0.05),and the expression levels of Bax and Caspase-3 proteins were significantly decreased(P<0.05).Conclusion:Acupuncture can promote the differentiation of quadriceps muscle satellite cells and inhibit muscle cell apoptosis in the model rats with KOA,and the mechanism may be related to the up-regulation of expressions of IL-6,JAK,and STAT3 proteins in the quadriceps muscle tissue.
