Objective:To investigate the interventional effect of Rhizoma Corydalis on mice with ulcerative colitis(UC)induced by dextran sulfate sodium(DSS),as well as the potential mechanism of Rhizoma Corydalis in the treatment of UC based on metabolomics and inflammation biomarkers.Methods:A mouse model of UC was established,and then the mice were divided into model group,high-dose group(1.517 g/kg crude drug),middle-dose group(0.986 g/kg crude drug),low-dose group(0.455 g/kg crude drug),and positive drug group(5-aminosalicylic acid at a dose of 718.8 mg/kg),while the mice without modeling were selected as normal group(0.9%NaCl by gavage).The mice in each group were administered for 7 consecutive days,and phenotypic parameters were dynamically moni-tored,such as body weight change,disease activity index(DAI),mean daily food intake,and daily water intake.The mice were sacri-ficed after 7 days to collect serum and colon tissue samples;ELISA was used to measure the serum levels of the proinflammatory fac-tors interleukin-6(IL-6),interleukin-17A(IL-17A),C-reactive protein(CRP),and tumor necrosis factor-α(TNF-α),and ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)was used to perform the non-targeted metabolomics analysis and compare the differences in se-rum metabolite profiles between groups.The mice were selected for modeling and validation with the same method,and glutathione(GSH)was selected as the positive drug.Colon length and mucosal damage were assessed,and quantitative real-time PCR was used to measure the relative mRNA expression levels of the key genes in the glutathione synthesis pathway(γ-glutamylcysteine synthetase[γ-GCS]and oxidative stress regulators yap1p and skn7)and mito-chondrial GSH transporter protein(Slc25a39)in colonic tissue.Results:Rhizoma Corydalis significantly improved weight loss,DAI,and colon length in a dose-dependent manner in the model animals,and there were reductions in the serum levels of IL-6,CRP,and TNF-α,while it had no significant effect on IL-17A.The metabolomics analysis revealed 21 potential biomarkers associated with amino acid and lipid metabolism,which were significantly regulated by Rhizoma Corydalis.In the verification experiment,both Rhi-zoma Corydalis and GSH exerted a significant protective effect against colonic mucosal damage without affecting colon length.Rhizoma Corydalis upregulated the expression of genes associated with glutathione synthesis,especially γ-GCS,suggesting that Rhizoma Co-rydalis could enhance intestinal antioxidant defenses.Conclusion:Rhizoma Corydalis has a therapeutic potential in a mouse model of DSS-induced UC and can alleviate symptoms,reduce the serum levels of inflammatory markers,and regulate metabolic pathways,and upregulation of the genes associated with glutathione synthesis suggests that the drug can enhance intestinal antioxidant defenses.

ObjectiveTo evaluate the effectiveness of stone needle thermocompression and massage compared to flurbiprofen gel patch in relieving chronic musculoskeletal pain in the shoulder and back， and to explore the potential mediating mechanism through muscle elasticity. MethodsA total of 120 patients with chronic musculoskeletal pain in the shoulder and back were randomly assigned to either stone needle group or flurbiprofen group， with 60 patients in each. The stone needle group received stone needle thermocompression and massage for 30 minutes， three times per week； the flurbiprofen group received flurbiprofen gel patch twice daily. Both groups were treated for 2 weeks. Pain improvement， as the primary outcome， was assessed using the Global Pain Scale （GPS） at baseline， after 2 weeks of treatment， and again 2 weeks post-treatment. To explore potential mechanisms， a mediator analysis was conducted by measuring changes in superficial and deep muscle elasticity using musculoskeletal ultrasound at baseline and after the 2-week treatment period. ResultsThe stone needle group showed significantly greater pain relief than the flurbiprofen group 2 weeks post-treatment. After adjusting for confounders related to pain duration， the between-group mean difference was -8.8 ［95% CI （-18.2， -0.7）， P＜0.05］. Part of the therapeutic effect was mediated by changes in deep muscle elasticity， with a mediation effect size of -1.5 ［95% CI （-2.0， -0.9）， P = 0.024］， accounting for 17.9% of the total effect. ConclusionStone needle thermocompression and massage can effectively relieve chronic musculoskeletal pain in the shoulder and back， partly through a mediating effect of improved deep muscle elasticity.

Objective: This study aimed to investigate the impact of bladder volume on dosimetric outcomes of organs at risk (OARs) in postoperative volumetric-modulated arc therapy (VMAT) for patients with cervical cancer. Methods: The study included 71 cervical cancer patients who received radical hysterectomy and postoperative VMAT between January 2020 and January 2023. Patients were divided into 3 groups according to average bladder volume observed in computed tomography simulation positioning images: Group A (<300 mL), Group B (300–500 mL), and Group C (≥500 mL).The study compared dosimetric parameters(V30 , V40 , V45 , and D2cc ) for OARs like the bladder, rectum, small intestine, and sigmoid colon, as well as the incidence of radiation cystitis and proctitis among these groups. Results: The median follow-up of the cohort was 33 months, with a median patient age of 48 years. Group A demonstrated the highest V40 and V45 values for the bladder (p<0.05).Conversely, Group C displayed the highest values for the V40 and V45 of the rectum, as well as the V45 and D2cc of the sigmoid colon (p<0.05). No statistically significant differences were observed in the incidence of acute radiation cystitis and radiation cystitis among the 3 groups. Significant difference was observed in the incidence rates of late radiation cystitis (p<0.05) and radiation proctitis (p<0.05) among the 3 groups. Group A exhibited the highest prevalence of late radiation cystitis, whereas Group C demonstrated the highest prevalence of late radiation proctitis. Conclusion Bladder volume significantly affects dosimetry of the bladder, rectum, and sigmoid colon in postoperative VMAT for cervical cancer patients. A recommended bladder volume of 300–500 mL helps reduce radiation-induced cystitis and proctitis.

In clinical surgery,various anesthetic drugs produce different effects on the blood circulation of patients.For example,propofol and inhaled anesthetics may lead to dose-related cardiovascular depression,meanwhile which is accompanied by sympathetic nerve tensile decline,vascular resistance decrease and is easy to induce postoperative hypotension.Ketamine can activate the sympathetic nervous system leading to release catecholamines and inhibit the vagus nerve,thus which is clinically manifested as increased blood pressure,in-creased heart rate and other cardiovascular excitation characteristics.As the dextroisomer-isomer of ketamine,esketamine(S-ketamine)not only retains the properties of ketamine,but also has relatively few side effects.Currently,it has been used in clinical anesthesia induction and maintenance,analgesia and treatment of refrac-tory depression.This paper provides a comprehensive overview of the effects of ketamine and S-ketamine on the hemodynamics of general anesthesia.
