Object To study the efficacy and potential mechanism of Tongbianling capsule in constipation. Methods The effects of Tongbianling capsule on intestinal motility in normal mice and carbon powder propulsion rate in small intestine of constipation model mice after were observed administration. The potential targets and key pathways of Tongbianling capsule in treating constipation were identified through network pharmacology. To verify the mechanism, the expression of p-PI3K/PI3K, p-AKT/AKT and CASP3 proteins in mouse colon tissue was detected by the western blot. Results The time for mice to excrete the first black stool was shortened and the number of fecal particles was increased in Tongbianling capsule administration group, and the carbon powder propulsion rate of mice in each Tongbianling capsule administration group was increased. The results of network pharmacology showed that treatment of constipation by Tongbianling capsule may be related to signaling pathways such as PI3K-Akt signaling pathway and 5-HT. The protein expression of p-PI3K/PI3K, p-AKT/AKT, and CASP3 in mouse colon tissue could be significantly downregulated in administration group. Conclusion Tongbianling capsule could effectively promote intestinal peristalsis in mice, increase the frequency of defecation, and effectively treat constipation. The mechanism of its action may be related to the direct or indirect regulation of intestinal motility by the PI3K-Akt signaling pathway.

Objective To explore the predictive value of coronary artery calcium score(CACS)combined with C-X-C motif chemokine ligand 12(CXCL12)and soluble CD40 ligand(sCD40L)for major adverse cardiovascular events(MACE)within 5 years in patients with stable coronary artery disease(SCAD).Methods A total of 206 elderly SCAD patients admitted in our depart-ment from March 2015 to November 2018 were recruited,and according to whether MACE occurred within 5 years of follow-up,they were divided into MACE group(42 cases)and control group(164 cases).Multivariate logistic regression analysis was performed to identify the inde-pendent predictors of MACE.ROC curve analysis was applied to evaluate the predictive value of the combined model,and its area under curve(AUC)value was calculated.Results Compared with the control group,the MACE group had significantly older age,larger proportions of hyper-tension and diabetes mellitus,higher CACS,and elevated CXCL12 and sCD40L levels(P＜0.05,P＜0.01).Multivariate logistic regression analysis revealed that age,hypertension,diabetes melli-tus,CACS,CXCL12 and sCD40L were independent risk factors for MACE in the elderly SCAD patients within 5 years(P＜0.05,P＜0.01).ROC curve analysis indicated that the AUC value of CACS,CXCL12,sCD40L,and these three indicators combined together in predicting MACE in elderly SCAD patients within 5 years was 0.872(95％CI:0.819-0.915),0.768(95％CI:0.704-0.824),0.726(95％CI:0.660-0.786),and 0.935(95％CI:0.893-0.965),respectively,with the value of the combination obviously higher than that of each indicator alone(P＜0.01).Conclusion Increased CACS,CXCL12 and sCD40L have predictive value for MACE in elderly SCAD patients,and the combination of the three indicators has obvious advantages in the prediction.

Objective To investigate the role of cathepsin K(CTK)and secreted frizzled-related protein 2(sFRP2)in ventricular remodeling in very old patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI),and analyze the correlation.Methods A total of 192 very old AMI patients undergoing PCI in our department from January 2020 to December 2023 were recruited,and based on clinical outcomes at 6 months after surgery,they were assigned into a ventricular remodeling group(74 cases)and a non-ventricular remodeling group(118 cases).The clinical data and postoperative biochemical indicators were collected in the two groups.Multivariate logistic regression analysis was performed to assess the correlation between CTK and sFRP2 levels and ventricular remodeling.ROC curves were plotted to analyze the predictive value of CTK and sFRP2 in ventricular remodeling.Results The ventricular remodeling group had significantly longer length of hospital stay,larger left ventricular end-diastolic diameter,and higher levels of CTK,sFRP2,C-reactive protein(CRP)and IL-6,but lower left ventricular ejection fraction than the non-ventricular remodeling group(P＜0.05,P＜0.01).Multivariate logistic regression analysis suggested that CTK and sFRP2 were independent risk factors for postoperative ventricular remodeling in very old AMI patients(P＜0.01).ROC curve analysis manifested that the area under curve value of CTK,sFRP2,CRP and IL-6 combined together in predicting ventricular remodeling in very old AMI patients after PCI was 0.892,with a sensitivity of 79.73％and a specificity of 88.14％(P＜0.01).Conclusion CTK and sFRP2 are significantly increased in ventricular remodeling in very old AMI patients after PCI,and are closely related to the occurrence of ventricular remodeling.They can be used as potential biomark-ers in the prediction of ventricular remodeling and provide important reference for clinical diagno-sis and treatment.

Objective:To explore the intervention effects of the skill training for parents with autism child (STPAC) on toddlers with autism spectrum disorder (ASD).Methods:A multicenter non-randomized concurrent controlled study design was conducted. Thirty children with ASD aged 15-30 months, first diagnosed at the Children′s Hospital of Fudan University, the First Hospital of Jilin University, and Chengdu Women′s and Children′s Central Hospital from 2019 to 2020, were enrolled in the STPAC group. Thirty children with ASD who visited the same hospitals during the same period but refused the STPAC intervention were selected as the control group. The STPAC group received an 8-week intervention (3 h/week) followed by quarterly follow-ups for 1 year, while the control group voluntarily chose community-based routine interventions. The Griffiths development scales-Chinese (GDS-C) was used to assess the developmental levels, and the communication and symbolic behavior scales developmental profile infant-toddler checklist (CSBS-DP-ITC) was completed by the primary caregivers to evaluate social, language and symbolic behavior. The independent samples t-tests or Mann-Whitney U tests, etc.was used for inter-group comparison. The paired t-tests or Wilcoxon signed-rank tests, etc. was used for inter-group pre-post intervention comparison. Results:The STPAC group included 30 children (22 males and 8 females, aged (23.9±2.2) months), and the control group included 30 children (20 males and 10 females, aged (24.2±2.6) months). Before the intervention, there were no statistically differences in GDS-C development quotient (DQ) and CSBS-DP-ITC scores between groups (all P>0.05). After 1-year intervention, GDS-C DQ in personal-social, hearing-language, hand-eye coordination, performance domains of STPAC group and GDS-C DQ in personal-social, hearing-language domains of control group were all increased (all P<0.01). After 1-year intervention, CSBS-DP-ITC scores of both groups were all improved in socia, language, symbolic behavior, and total scores (all P<0.001). GDS-C DQ changes before and after 1 year of intervention in hearing-language, hand-eye coordination, performance domains of the STPAC group were all higher the those of control group (34(15, 48 vs. 10(-4, 39), 11±20 vs. -1±19, 23±25 vs. 8±22, all P<0.05). CSBS-DP-ITC scores changes before and after 1 year of intervention in social and total scores of the STPAC group were both higher the those of control group (10(5, 30) vs. 3(1, 7), 26±17 vs. 11±8, both P<0.001). Conclusion:Compared with the community routine interventions, the STPAC better improves the language, hand-eye coordination, visual-spatial, social communication, and play skills in ASD toddlers.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

OBJECTIVE: To determine the role of Tripterygium wilfordii multiglycoside (TGW) in the treatment of psoriatic dermatitis from a cellular immunological perspective. METHODS: Mouse models of psoriatic dermatitis were established by imiquimod (IMQ). Twelve male BALB/c mice were assigned to IMQ or IMQ₊TGW groups according to a random number table. Histopathological changes in vivo were assessed by hematoxylin and eosin staining. Ratios of immune cells and cytokines in mice, as well as PAM212 cell proliferation in vitro were assessed by flow cytometry. Pro-inflammatory cytokine expression was determined using reverse transcription quantitative polymerase chain reaction. RESULTS: TGW significantly ameliorated the severity of IMQ-induced psoriasis-like mouse skin lesions and restrained the activation of CD45⁺ cells, neutrophils and T lymphocytes (all P<0.01). Moreover, TGW significantly attenuated keratinocytes (KCs) proliferation and downregulated the mRNA levels of inflammatory cytokines including interleukin (IL)-17A, IL-23, tumor necrosis factor α, and chemokine (C-X-C motif) ligand 1 (P<0.01 or P<0.05). Furthermore, it reduced the number of γ δ T17 cells in skin lesion of mice and draining lymph nodes (P<0.01). CONCLUSIONS TGW improved psoriasis-like inflammation by inhibiting KCs proliferation, as well as the associated immune cells and cytokine expression. It inhibited IL-17 secretion from γ δ T cells, which improved the immune-inflammatory microenvironment of psoriasis.
