ObjectiveTo systematically review the effect of dual-task training (DTT) on mobility and balance in stroke patients. MethodsCNKI, Wanfang Data, VIP, PubMed, Web of Science, Embase and Cochrane Library were searched for randomized controlled trials (RCT) on DTT in stroke rehabilitation from inception to June, 2025. The quality of the included studies was assessed using the Cochrane Risk of Bias Tool and the PEDro scale. Meta-analysis was performed using RevMan 5.4. ResultsA total of eleven RCT involving 517 stroke patients were included, and the scores of PEDro scale were four to eight. DTT was more effective on the score of Fugl-Meyer Assessment-Lower Extremity (MD = 3.70, 95%CI 1.88 to 5.53, P < 0.001) and Berg Balance Scale (BBS) (MD = 3.04, 95%CI 1.58 to 4.49, P < 0.001), fall incidence (OR = 0.32, 95%CI 0.11 to 0.87, P = 0.025), gait speed under a single-task condition (MD = 0.08, 95%CI 0.03 to 0.12, P = 0.002), gait speed under a dual-task condition (MD = 0.13, 95%CI 0.10 to 0.16, P < 0.001), Timed Up and Go Test time (MD = -2.78, 95%CI -3.85 to -1.72, P < 0.001), and score of modified Barthel Index (MD = 4.77, 95%CI 1.88 to 7.66, P = 0.001). Subgroup analysis indicated that motor-motor DTT was more effective than cognitive-motor DTT on BBS scores and single-task gait speed. ConclusionsDTT can improve mobility and balance in stroke patients, especially with motor-motor tasks.

Objective To investigate the effect of osthole(Ost)on neuroinflammation in IS rats by regulating the HMGB1-RAGE signaling pathway.Methods After rat IS model was established with middle cerebral artery occlusion by intraluminal suture,40 model rats were grouped into model group,low-and high-dose Ost(Ost-L and Ost-H)groups,and Ost-H+recombinant rHMGB1(Ost-H+rHMGB1)group,with 10 rats in each groups.Another 10 rats served as sham operation group.Zea-Longa scoring was used to evaluate the neurological function.Serum nerve growth factor(NGF)and LDH levels,and hippocampal TNF-α,IL-10,and IL-1β contents were detected by ELISA.Triphenyltetrazolium chloride staining,Nissl staining,and TUNEL staining were applied respectively to observe the volume of cerebral infarction,hippocampal morphology,and apoptosis in hippocampal tissue cells.The activity of superoxide dismutase(SOD)in the hip-pocampus was detected by hydroxylamine assay,and that of catalases(CAT)was by ammonium molybdate.The content of malonic dialdehyde(MDA)was determined by thiobarbituric acid method.Western blotting was used to measure the protein expression of cleaved Caspase-3,HMGB1,RAGE,NF-κB,and p-NF-κB in brain tissue.Results The model group showed obvious damage in the hippocampal tissues,higher neurological function score,increased stroke volume percentage,serum LDH level and hippocampal TNF-α and IL-1βlevels,elevated neuronal apoptot-ic rate and MDA content,and up-regulation of cleaved Caspase-3,HMGB1,RAGE,and p-NF-κB/NF-κB proteins,while decreased serum NGF level,hippocampal IL-10 content and SOD and CAT activities when compared with the sham group(P＜0.05).Low-and high-dose Ost treatment re-sulted in obviously declined damage in the hippocampal tissue,decreased neurological function score,lower stroke volume percentage,reduced serum LDH level and hippocampal tissue TNF-αand IL-1β contents,lower neuronal apoptotic rate and MDA content,and down-regulated cleaved Caspase-3,HMGB1,RAGE,and p-NF-κB/NF-κB protein,while raised serum NGF level,hipp-ocampal IL-10 content and SOD and CAT activities when compared with the model group(265.84±34.76 pg/ml and 394.52±41.68 pg/ml vs 187.56±23.54 pg/ml,P＜0.05;41.84±5.67 pg/ml and 68.57±8.39 pg/ml vs 16.73±3.52 pg/ml,P＜0.05;87.49±12.53 U/mg and 109.86±14.67 U/mg vs 52.73±8.46 U/mg,P＜0.05;45.38±5.72 U/mg and 67.43±8.91 U/mg vs 21.54±3.47 U/mg,P＜0.05).rHMGB1 could alleviate the improvement effect of Ost on nerve damage in IS rats.Conclusion Ost can attenuate neuroinflammation,oxidative stress,and neuronal apoptosis in IS rats,which may be through its inhibiting the HMGB1-RAGE signaling pathway.

Objective To investigate the effects of electroacupuncture at"Zusanli"(ST36)on type 3 innate lymphoid cells(ILC3s)secreting interleukin(IL)-22 and intestinal cholinergic neurons in the colon of mice with inflammatory bowel disease(IBD),and to explore the mechanisms underlying electroacupuncture-mediated amelioration of IBD.Methods Twenty-four male C57BL/6J mice were divided into a normal group(n=8)and a modeling group(n=16)using the random number table method.The modeling group received 4％dextran sulfate sodium solution ad libitum for 7 days to establish the IBD model.On the fourth day after modeling,the modeling group was divided into a model group and an electroacupuncture group using the random number table method,with eight mice per group.Electroacupuncture intervention was applied bilaterally at"Zusanli"(ST36)in mice of the electroacupuncture group,once daily for 20 min each time,for seven consecutive days.After intervention,stool characteristics and occult blood were assessed.The disease activity index(DAI)of mice in each group was scored,and colon length was measured.The morphology of the colon tissue in mice was observed using hematoxylin-eosin staining,and the histopathological score was determined.A cytometric bead array was used to detect the contents of IL-1β,tumor necrosis factor-α(TNF-α),and IL-6 in colon tissue.Flow cytometry was used to determine the IL-22+ILC3s proportion in lamina propria lymphocytes of colon tissue.The content of IL-22 in colon tissue was detected using an enzyme-linked immunosorbent assay.Immunofluorescence was used to detect the number of choline acetyltransferase(ChAT)+/cellular Fos(c-Fos)+co-labeled neurons in colon tissue.Results Compared with the normal group,mice in the model group exhibited different degrees of loose stools,strongly positive fecal occult blood test,elevated DAI scores,shortened colon length,increased colon histopathological score;increased contents of IL-1β,TNF-α,and IL-6 in colon tissue;and a decreased IL-22+ILC3s proportion in lamina propria lymphocytes of colon tissue(P＜0.05).Compared with the model group,mice in the electroacupuncture group exhibited improved fecal traits,weakly positive fecal occult blood test,decreased DAI score,increased colon length,reduced colon histopathological score;decreased contents of IL-1β,TNF-α,and IL-6 in colon tissues;an increased IL-22+ILC3s proportion in lamina propria lymphocytes of colon tissue;increased IL-22 content in colon tissue;and increased ChAT+/c-Fos+co-labeled neurons in colon tissue(P＜0.05).Conclusion Electroacupuncture at"Zusanli"(ST36)can significantly ameliorate colonic damage and reduce inflammatory responses in IBD mice,and its mechanism may be related to the activation of intestinal cholinergic neurons and the enhancement of colonic ILC3s function.

Objective To identify high-risk factors for healthcare-associated infection(HAI)in patients in inten-sive care units(ICUs),and develop a quick response(QR)code-based APP prediction tool.Methods Information of inpatients in general ICUs of three hospitals in Guizhou Province from January to December 2024 were collected.Risk factors were analyzed with a logistic regression model.QR code-based APP was constructed and validated.Results A total of 1 782 patients in general ICUs of three hospitals in Guizhou Province in 2024 were included in the analysis,out of which 410 were HAI cases,and the incidence of HAI was 23.01％.Multivariate logistic regre-ssion analysis results of HAI in ICU inpatients showed that regional gross domestic product(GDP)≥58 685 Yuan,performing pathogen culture during this hospitalization,history of diabetes mellitus,history of cancer,length of hospital stay ≥7 days before infection,and duration of persistent fever＞5 days before infection were independent risk factors for HAI in ICU patients(all P＜0.05).The discrimination of the model(area under the receiver operating characteristic curve[AUC]of 0.841),calibration(Brier score of 0.129),and clinical effectiveness(net benefit of 11.4％when the risk threshold was 5％-74％)all performed well.Conclusion The QR code-based APP prediction tool is of great significance for scientific research transformation and precise HAI control.

Objective To investigate the impact of donor kidney histopathological lesions on the risk of BK virus (BKV) infection and progression after kidney transplantation. Methods A retrospective analysis was conducted on the clinical data of 326 kidney transplant recipients from deceased donors at the Department of Kidney Transplantation, the First Affiliated Hospital of Zhengzhou University, from January 2019 to June 2020. The recipients were divided into two groups based on whether BKV infection occurred after kidney transplantation: the BKV infection group (145 cases) and the non-BKV infection group (181 cases). The correlation between donor kidney histopathological findings from zero-hour biopsy and BKV infection, as well as the impact on the risk and progression of BKV infection, was analyzed. Results The incidence of BKV infection among the 326 kidney transplant recipients was 44.5% (145/326). The clearance rate of BKV after infection was 82.1% (119/145), while 17.9% (26/145) progressed to BKV viremia. Among the 326 qualified kidney biopsy specimens, 32 cases showed mild tubular atrophy, 324 cases had mild acute tubular injury, 27 cases exhibited mild hyaline arteriosclerosis, 10 cases had moderate to severe hyaline arteriosclerosis, 7 cases showed mild interstitial inflammation, 23 cases had mild interstitial fibrosis, 6 cases exhibited mild arterial intimal fibrosis, and 1 case had moderate to severe arterial intimal fibrosis. Multivariate logistic regression analysis revealed that male recipients, donor age and tubular atrophy were independent risk factors for BKV infection (all P<0.05). Tubular atrophy was also an independent risk factor for the progression from BKV uria to BKV viremia (P<0.05). Conclusions Donor kidney histopathological lesions have a certain impact on BKV infection and progression after kidney transplantation. Patients with more severe tubular atrophy in donor kidneys have a higher risk of BKV infection after kidney transplantation and are more likely to progress to BKV viremia.
