OBJECTIVE To explore the intervention mechanism of Bushen anzhi decoction （BSAZD） in rats with insomnia induced by kidney failing to store spirit. METHODS A total of 36 SD rats were randomly divided into normal group （normal saline）， model group （normal saline）， eszopiclone group （positive control group， 0.27 mg/kg）， and low-， medium- and high-dose BSAZD groups （5.85， 11.70， 23.40 g/kg）， with 6 rats in each group. Except for the normal group， rats in the remaining groups were subjected to combined administration of D-galactose and DL-4-chlorophenylalanine to establish the rat model of insomnia due to kidney failing to store spirit. After successful modeling， corresponding liquid medicine or normal saline was intragastrically administered once daily for 14 consecutive days. After the last administration， behavioral indicators and hippocampal histopathological morphology of rats were detected. Untargeted metabolomics was adopted to screen serum differential metabolites and enrich relevant signaling pathways. RESULTS Compared with the model group， the high-dose BSAZD group exhibited significantly increased open arm entries ， open arm time and sleep time （ P ＜0.05）， accompanied by markedly decreased closed arm entries， closed arm time and sleep latency （ P ＜0.05）. Hippocampal neurons in the high-dose BSAZD group were arranged regularly， and the size， morphology and location of cell nuclei were nearly normal. Untargeted metabolomics analysis identified oxidized glutathione， glutamate and other differential metabolites in serum of rats in the high-dose BSAZD group； these differential metabolites were mainly enriched in GABAergic synapse， glutamatergic synapse， cAMP signaling pathway and 2-oxocarboxylic acid metabolism pathway. CONCLUSIONS BSAZD can improve sleep quality， relieve anxiety-like behaviors in rats with insomnia due to kidney failing to store spirit. Its therapeutic mechanism may be associated with regulating GABAergic and glutamatergic synaptic pathways to restore neurotransmitter balance and further alleviate oxidative stress injury， modulating the cAMP signaling pathway to facilitate neural repair， and intervening the 2-oxocarboxylic acid metabolism pathway to optimize energy supply.

Objective To investigate the mechanism of the miR-518a-5p/histone deacetylase 6(HDAC6)axis in DNA oxidative damage in ovarian cancer(OC)SKOV3 cells.Methods Expression levels of miR-518a-5p and HDAC6 mRNA in OC tissues and in various cancer cells(A2780,SKOV3,CAOV3)were detected by qRT-PCR.SKOV3 cells were separated into Control,miR-NC,miR-518a-5p mimics,miR-518a-5p mimics+pcDNA-NC,and miR-518a-5p mimics+pc-HDAC6 groups.Cell proliferation and apoptosis were analyzed by colony-forming assay and Hoechst 33258 staining.Expression of phosphorylated histone H2AX(γ-H2AX)was detected by immunofluorescence assay and reactive oxygen species(ROS)were detected by flow cytometry.HDAC6,Bcl-2-associated X protein(Bax),and B-cell lymphoma-2(Bcl-2)protein expression were analyzed by Western blot.The regulatory relationship between miR-518a-5p and HDAC6 was analyzed by dual luciferase assay.The effect and mechanism of miR-518a-5p on oxidative DNA damage in OC cells were studied in a xenotransplantation tumor model.Results miR-518a-5p expression was decreased and HDAC6 expression was increased in OC tissues and A2780,SKOV3,and CAOV3 cells(P＜0.001).Expression levels of miR-518a-5p were lowest and expression levels of HDAC6 were highest in SKOV3 cells,and SKOV3 cells were therefore selected for subsequent experiments.miR-518a-5p expression,apoptosis rate,number of γ-H2AX-positive cells,relative ROS fluorescence intensity,and expression of Bax were all higher in the miR-518a-5p mimics group compared with the miR-NC group,while HDAC6 mRNA and protein expression,Bcl-2 expression,and colony-formation number were all lower(P＜0.001).HDAC6 mRNA and protein expression,colony-formation number,and expression of Bcl-2 were higher in the miR-518a-5p mimics+pc-HDAC6 group compared with the miR-518a-5p mimics+pcDNA-NC group,and the apoptosis rate,number of γ-H2AX-positive cells,relative ROS fluorescence intensity,and expression of Bax were all lower(P＜0.001).HDAC6 had a targeted regulatory relationship with miR-518a-5p.Overexpression of miR-518a-5p decreased tumor volume,weight,and HDAC6 protein expression in tumor tissues,and increased γ-H2AX expression in vivo(P＜0.001).Upregulation of HDAC6 expression by overexpression of miR-518a-5p increased graft tumor volume,weight,and HDAC6 protein expression and decreased γ-H2AX-positive expression(P＜0.05).Conclusions miR-518a-5p expression is reduced and HDAC6 expression is increased in OC tissues and cells.Overexpression of miR-518a-5p can induce oxidative DNA damage in SKOV3 cells by inhibiting HDAC6 expression,thereby inhibiting cell proliferation and promoting cell apoptosis.

Osteofascial compartment syndrome(OCS)is a serious complication frequently occurring in the orthopedic department,and delayed treatment may result in irreversible limb damage.With the increase of traffic trauma accidents in modern times,the incidence and disability risk of OCS have increased,so it has been widely concerned by medicine.Based on the clinical characteristics of OCS in traditional Chinese and Western medicine,this paper summarized the commonly used animal models of OCS by referring to CNKI and PubMed literature,and evaluated the data of the animal models'coincidence in combination with clinical diagnostic criteria,analyzed the comprehensive characteristics of the models,and provided a feasible reference for the animal models in the treatment of OCS in modern traditional Chinese and Western medicine.The results showed that the most commonly used OCS model was the rabbit model,which was constructed with pressure damage.Most of the methods are provided by foreign research institutes,but there is no research on the model of combining disease and syndrome of OCS with traditional Chinese and Western medicine,which brings certain obstacles to disease research.Therefore,this study summarized the advantages and disadvantages of the existing model of OCS through a large number of literature analysis,and put forward suggestions for the preparation of the model of combining traditional Chinese and Western medicine with fundamental theories of traditional Chinese and Western medicine.

AIM To investigate the protective effects of the aqueous extract of Bulbophyllum kwangtungense Schltr.on D-galactose(D-gal),an oxidative stress-induced liver damage in rats.METHODS 60 Male SD rats were randomly divided into the normal control group,the model group,the resveratrol group(20 mg/kg),and low-dose,medium-dose,and high-dose B.kwangtungense aqueous extract groups(750,1 500 and 3 000 mg/kg).Except for those of the normal control group,the rats of the other groups were subcutaneously injected with D-gal(200 mg/kg)in the back of neck to establish a liver damage model.Simultaneously,each group underwent the corresponding drug administration by gavage(10 mL/kg)once daily for 42 days.After the treatment period,the rats had their peripheral blood and liver tissues collected for the calculation of the liver index;their serum AST and ALT activities,hepatic SOD and GSH-Px activities,and MDA levels measured;their hepatic pathological changes observed using HE staining;their hepatic mRNA expressions of Nrf2,NQO-1 and HO-1 detected by RT-qPCR;and their hepatic protein expressions of Nrf2,NQO-1,HO-1,Bax,Bcl-2 and cleaved Caspase-3 measured by Western blot.RESULTS Compared with the model group,the groups intervened with medium-dose or high-dose B.kwangtungense aqueous extract showed increased liver index level(P＜0.01);decreased serum AST and ALT activities(P＜0.01);increased hepatic SOD and GSH-Px activities(P＜0.05,P＜0.01);reduced MDA levels(P＜0.01);alleviated pathological liver damage and increased hepatic mRNA and protein expressions of Nrf2,NQO-1 and HO-1(P＜0.05,P＜0.01);and reduced protein expressions of cleaved Caspase-3 and the Bax/Bcl-2 ratio as well(P＜0.05,P＜0.01).CONCLUSION The aqueous extract of B.kwangtungense is protective of rats with D-gal-induced liver injury,and the underlying mechanism may associate with the inhibition of oxidative stress and the suppression of hepatocellular apoptosis mediated by the activation of the Nrf2/HO-1/NQO-1 signaling pathway.

AIM To study the protective effect of Gynura divaricate polysaccharide on gouty nephropathy(GN)induced by dry yeast combined with adenine in rats.METHODS Sixty male SD rats were randomly divided into the normal group,the model group,the allopurinol group(42 mg/kg),and the low-dose,medium-dose and high-dose G.divaricate polysaccharide groups(140,280,560 mg/kg).All the rats except those of the normal group were induced into GN models by intragastrical dosing of yeast(5 g/kg)and adenine(100 mg/kg)and intervened with corresponding drug administration simultaneously.After 35 days,the rats had their levels of creatinine(Cr)and uric acid(UA)in serum and urine detected and their fraction excretion of uric acid(FEUA)value determined;their kidney mass and volume measured and their levels of kidney index and density calculated;their renal pathological changes checked by HE staining;their renal GLUT9,URAT1,ABCG2 and OAT1 mRNA expressions dectected by RT-qPCR;and their renal GLUT9,URAT1,ABCG2 and OAT1 protein expressions dectected by Western blot.RESULTS Compared with the model group,each dose of G.divaricate polysaccharide group displayed decreased levels of kidney mass,kidney volume and kidney index(P＜0.01);increased levels of kidney density(P＜0.05,P＜0.01);decreased serum levels of UA and Cr(P＜0.01);increased urine levels of UA and Cr(P＜0.01);increased FEUA value(P＜0.01);decreased GLUT9,URAT1 mRNA and protein expressions(P＜0.05,P＜0.01);and increased ABCG2,OAT1 mRNA and protein expressions(P＜0.05,P＜0.01);and more alleviated renal histological aberrations.CONCLUSION G.divaricate polysaccharide exerts good protective effects against yeast/adenine-induced GN in rats probably through down-regulating protein expression of GLUT9,URAT1 and up-regulating ABCG2 and OAT1.

Bruton's tyrosine kinase inhibitors (BTKi) are a class of novel small-molecule targeted antitumor drugs used to treat B-cell malignancies. However, safety issues associated with BTKi may lead to treatment interruption, compromising their efficacy. To promote the standardized management of safety in BTKi treatment, Evidence-Based Pharmacy Professional Committee of the Chinese Pharmaceutical Association, Hospital Pharmacy Professional Committee of the Chinese Pharmaceutical Association, Division of Therapeutic Drug Monitoring of Chinese Pharmacological Society, Expert Committee on Lymphoma of Chinese Society of Clinical Oncology, Expert Committee on Leukemia of Chinese Society of Clinical Oncology, Integrated Cancer Cardiology Branch of China Anti-Cancer Association, Hematology Branch of the Chinese Medical Association, and Hospital Pharmacy Professional Committee of the Cross-Straits Medicine Exchange Association formulated the Evidence-based Expert Consensus on the Clinical Management of Safety of Bruton′s Tyrosine Kinase Inhibitors (2024), which was published in the Chinese Journal of Cancer Research in June 2024. It covered 9 clinical issues in the following 3 domains: (1) the management of common adverse reactions of BTKi such as bleeding, cardiovascular events, hematological toxicity, infections, rashes, diarrhea, and arthralgia; (2) the management of drug-drug interactions; (3) management guidance for special populations. This consensus provides evidence-based recommendations for the safety management of BTKi medication in clinical practice. This article provides an interpretation and evidence summary of the consensus in Chinese, aiming to facilitate its implementation in China, enhance the safety management of BTKi treatment, and improve patient outcomes.
