Objective:To verify mechanism of Dunhuang Ruicao ointment in frostbite treatment through network pharmacology and experiment.Methods:Targets of Dunhuang Ruicao ointment in intervention of frostbite was screened through network pharmacology.Dunhuang Ruicao ointment was used to treat rat model of frostbite.Effect of drug was observed and results of network pharmacological enrichment analysis were verified.Results:A total of 239 active drug components,186 disease targets and 36 common targets were screened.KEGG pathway enrichment screened out 96 pathways,mainly enriched in Toll-like receptor signaling pathway,IL-17 signaling pathway,tumor necrosis factor signaling pathway,AGE-RAGE signaling pathway,Th17 cell differentiation pathway,suggesting Toll-like receptor signaling pathway may play an important role in treatment of frostbite by Dunhuang Ruicao ointment.Animal experiments showed that compared with model group,skin frostbite of rats treated with different doses of Dunhuang Ruicao ointment group was significantly improved,wound healing rate was increased,swelling rate was decreased,wound tissue epithelialization was obvious,inflammatory infiltration was reduced,angiogenesis was increased,and collagen fiber content was increased.mRNA and protein expressions of TLR4,MyD88 and NF-κB p65 in local skin lesions were decreased to different degrees,and middle-dose group had the best effect.Conclusion:Dunhuang Ruicao ointment in treatment of frostbite has characteristics of multiple components,multiple targets,multiple pathways synergy,probably playing a role in treatment of frostbite by inhibiting TLR4/MyD88/NF-κB signaling path-way activated to reduce frostbite rats serum proinflammatory media release,reduce inflammation,improve rate of tissue remodeling,promote healing of frostbite,providing a theoretical basis for further study of complex mechanism of Dunhuang Ruicao ointment in treatment of frostbite.

Objective:To systematically evaluate the home care needs of the disabled elderly in China, to provide a reference for developing home care services oriented to the needs of the elderly.Methods:Qualitative studies on the need for home care services for the disabled elderly in China were electronically searched in PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP, WanFang Data, and China Biology Medicine disc. The search time limit was from the tstablishment of the database to March 9, 2024. The methodological quality of the included literature was evaluated using the quality evaluation criteria for qualitative research (2016) of the Joanna Briggs Institute Evidence-Based Health Care Center. The results of the qualitative study were analyzed using the convergent integration method.Results:A total of 12 articles were included, and 43 outcomes were distilled, summarized to form eight new categories, and synthesized to produce two outcomes, including medical care and rehabilitation needs (professional nursing needs, rehabilitation and exercise needs, health guidance needs, and psychological guidance needs), and supportive needs (policy support needs, home environment needs, service resource needs, and life care needs) .Conclusions:Disabled elderly have multifaceted needs for home care. It is recommended that a multidisciplinary team be formed and a multi-pronged integrated care model be adopted to meet the needs of the disabled elderly living at home.

Intestinal injury is a common adverse reaction of clinical chemotherapy drugs, which limits the further application of chemotherapy drugs and causes serious physical and mental burden to patients. At present, the mechanism of chemotherapy-induced intestinal injury is complex, and traditional Chinese medicine has an excellent preventive effect. This article reviews the related mechanisms of intestinal flora imbalance, oxidative stress, inflammatory response, cell apoptosis, and immune damage caused by chemotherapy, and summarizes the role of traditional Chinese medicine in prevention and treatment of oxidative stress, inflammatory response, cell apoptosis, and immune damage.
