Objective To explore the compatibility and combination patterns of traditional Chinese medicine(TCM)formulas in treating kidney deficiency and blood stasis type osteoporosis,to identify the most frequently used drug pairs,and to explore their mechanisms of action in treating kidney deficiency and blood stasis type osteoporosis through network pharmacology and molecular docking,providing theoretical guidance for clinical medication.Methods Formulas used for treating kidney deficiency and blood stasis type osteopo-rosis in the past 10 years were screened from databases such as CNKI and Wanfang.SPSS,Origin,and IBM SPSS Modeler software were used for frequency,taste and meridian statistics,and drug combination analysis.Cluster analysis was applied to identify the core drug combinations.The best drug pair for treating kidney de-ficiency and blood stasis type osteoporosis was selected.Network pharmacology analysis was conducted on this drug pair to identify core targets,main components,and signaling pathways.Molecular docking was performed using AutoDockTools,AutoDock Vina,and PyMOL software to further verify the possibility of their interac-tions.Results A total of 117 formulas containing 148 TCMs were screened out.The frequently used drugs and combinations were mainly kidney-yang and kidney-yin tonics and blood-activating and stasis-eliminating drugs,with sweet and warm tastes,mostly attributed to the liver and kidney meridians.Further cluster analy-sis of drugs with a frequency greater than 20 yielded five categories.The Epimedium-Bupleurum combination was selected for network pharmacology analysis,which identified 89 targets.Core targets included STAT3,IL-6,and JUN.Main components were cryptotanshinone,kaempferol,luteolin,and quercetin.Molecular docking was performed on the main components and core targets to verify the treatment effect of the drugs on osteopo-rosis.Conclusion TCM treatment of kidney deficiency and blood stasis type OP mainly focuses on tonifying the liver and kidney and activating blood circulation to remove stasis,supplemented by tonifying the spleen and boosting qi.This can provide a theoretical basis for the clinical treatment of OP.Additionally,the Epime-dium-Bupleurum drug pair can exert therapeutic effects on osteoporosis through a multi-target and multi-pathway mechanism,laying the foundation for subsequent experiments and clinical applications.

Nutritional support is an indispensable part in the treatment of critically ill patients with coronavirus disease 2019 (COVID-19). Critically ill COVID-19 patients are often in a state of high inflammation, high stress, high catabolism, and their energy consumption increases significantly. All critically ill patients with COVID-19 should be screened for nutritional risk with NRS-2002 or Nutric tool in the early stage. If there is a risk of malnutrition, subjective global assessment (SGA) or Global Leadership Initiative on Malnutrition (GLIM) are further used for malnutrition assessment. After assessment, the daily energy, protein, electrolyte and liquid quantity needed by the patients should be determined according to the actual condition. Then, according to the degree of gastrointestinal function impairment in patients, the oral nutrition supplement, enteral nutrition, parenteral nutrition or their combination are selected for nutritional support. For patients with normal gastrointestinal function who require prone position ventilation or receive extracorporeal membrane oxygenation (ECMO) treatment, enteral nutrition is recommended as the first choice. In addition, in the process of nutrition implementation, it is necessary to closely monitor the adverse reactions such as abdominal distention, diarrhea, regurgitation, phlebitis and liver function damage, timely adjust the nutrition program to ensure the smooth implementation of nutritional support. Based on the metabolic characteristics of critically ill patients with COVID-19, this paper makes a summary and suggestion on the following perspectives such as nutritional risk screening and assessment, target amount of nutritional treatment, nutritional intervention and treatment, nutritional support of special populations, and common adverse reactions in nutritional support treatment, so as to provide reference for individualized nutritional support therapy of critically ill patients with COVID-19.
