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 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.

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.

Background and purpose:Internal mammary sentinel lymph node biopsy(IMSLNB)is a minimally invasive diagnostic technique for regional lymph nodes in breast cancer,which can provide accurate lymph staging and guide adjuvant treatment decision,but its clinical application has been controversial.The purpose of this study was to investigate the prognosis of IMSLNB in early breast cancer.Methods:In this study,a retrospective cohort of 7 949 patients with breast cancer from January 1,2016 to December 31,2021 was analyzed.After applying propensity score matching,the patients were divided into IMSLNB group and no-IMSLNB group,and the regional recurrence-free survival(RRFS),local recurrence-free survival(LRFS),distant metastasis-free survival(DMFS),disease-free survival(DFS)and overall survival(OS)of the two groups were compared.This study was approved by the Clinical Research Ethics Committee of the Affiliated Tumor Hospital of Shandong First Medical University(approval number:SDTHEC20130324).Results:A total of 990 patients were included in the final analysis(330 in the IMSLNB group and 660 in the no-IMSLNB group).IMSLN metastasis was found in 54 patients in the IMSLNB group,including 47 patients with axillary lymph node(ALN)metastasis and 7 patients with IMSLN metastasis only.The IMSLN transfer rate was 16.4%.The median follow-up of 41 months showed that the IMSLNB group demonstrated better 3-year DFS[98.4%vs 94.2%,hazard ratio(HR)=0.509;95%CI:0.312-0.828,P=0.007]and 5-year DFS(92.5%vs 87.3%,HR=0.214,95%CI:0.206-0.222,P=0.011)compared with no-IMSLNB group.However,no significant differences were observed in 3-year OS(99.1%vs 99.4%,HR=0.618,95%CI:0.231-1.655,P=0.338)or 5-year OS(98.5%vs 99.1%,HR=0.52,95%CI:0.51-0.53,P=0.392)between the two groups.The 3-year RRFS in the IMSLNB group was better compared with the no-IMSLNB group(99.09%vs 97.73%,HR=0.066;95%CI:0.061-0.071,P=0.048),while no significant differences were observed in 3-year LRFS(99.70%vs 98.19%,HR=0.209;95%CI:0.201-0.217,P=0.130)or DMFS(95.76%vs 96.06%,HR=0.865,95%CI:0.858-0.872,P=0.820)between the two groups.The exploratory subgroup analysis of DFS revealed that patients in the following subgroups could significantly benefit from IM-SLNB(P＜0.05):diagnosis age(≤50 years),premenopausal status,BMI(≤24),lymphovascular invasion(LVI,present),tumor location(lateral),molecular subtype[hormone receptor positive(HR+)/human epidermal growth factor receptor 2 negative(HER2-)],histological type(invasive ductal carcinoma),and axillary lymph node status(positive).Conclusion:IMSLNB can provide more accurate regional lymph node staging for early breast cancer,help optimize adjuvant radiotherapy strategies,and improve patients'DFS and RRFS.It can be promoted as a minimally invasive staging technique for regional lymph nodes.

Background:To compare the efficacy and safety of monthly administrations of gonadotropin releasing hormone (GnRH) agonists LY01005 and Zoladex ? in Chinese patients with premenopausal breast cancer. Methods:From October 2020 to November 2021, 188 premenopausal breast cancer patients were enrolled in 34 hospitals and randomized 1:1 to receive either LY01005 or Zoladex ? every 28 days for a total of three injections. All patients concomitantly received oral tamoxifen (TAM). The primary efficacy endpoint was cumulative probability of maintaining menopausal level [oestradiol (E2) ≤30 pg/ml] from day 29 to day 85. The second efficacy endpoint included changes in E2, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) compared with the baseline. Pharmacokinetics (PK), pharmacodynamics (PD), and safety were analyzed. The study also evaluated the pharmacokinetic and pharmacodynamic characteristics of LY01005. Results:A total of 188 patients were randomised and 187 patients received either LY01005 or Zoladex ?. Cumulative probabilities of maintaining menopausal level (E2≤30 pg/ml) from day 29 to day 85 were 93.1% for LY01005 and 86.3% for Zoladex ?. The between-group difference was 6.8% (95% CI: -2.3%, 15.9%) and primary efficacy in the LY01005 group was not inferior to that in the Zoladex ? group. Changes in E2, LH, and FSH levels compared with the baseline were equivalent between the two groups (E2: 89.34% to 90.23% vs. 82.11% to 85.02%; LH: 88.89% to 95.52% vs. 89.70% to 97.02%; FSH: 75.36% to 80.85% vs.73.07% to 80.24%, respectively). After three consecutive doses of LY01005, the LH and FSH levels of the subjects showed a transient increase after the first dose, reached a peak on the second day and then started to decrease. The LH and FSH reached a lower level and remained at or below that level until the 85th day. Both treatments were well-tolerated. Conclusion:LY01005 is as effective as Zoladex ? in suppressing E2 to menopausal levels in Chinese patients with premenopausal breast cancer, with a similar safety profile.

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.

One-step nucleic acid amplification(OSNA)technology is a molecular diagnostic technology that assesses the metastatic status of lymph nodes by detecting the expression level of cytokeratin 19 mRNA in sentinel lymph nodes(SLNs).It is characterized by its rapidity,ac-curacy,semi-quantitative nature,and high reproducibility,thereby providing comprehensive lymph node diagnostic information for clinical physicians.It is of great significance regarding avoiding secondary axillary lymph node dissection(ALND)or excessive ALND.The de-escala-tion treatment pattern for breast cancer is the current therapeutic strategy pursued by surgeons.SLN biopsy(SLNB)can help patients re-ceive more precise and personalized treatment,thereby reducing unnecessary treatment intensity and side effects while ensuring thera-peutic efficacy.This article reviews the application of OSNA detection in SLNB.

The elderly are a high-risk group for cardiovascular diseases, and as they age, the function of the cardiovascular system gradually declines, leading to a significant increase in the risk of illness.The decline in cardiopulmonary function, abnormal blood pressure, metabolic issues such as blood lipids and glucose, and elevated levels of inflammatory factors are the main factors affecting cardiovascular health in the elderly.Resistance training, as an effective form of exercise intervention, can improve the cardiopulmonary function of the elderly, regulate abnormal states of indicators such as blood pressure, blood glucose, and blood lipids, and reduce the potential threat of inflammation to health.The article analyzes the effects of different training intensities, frequencies, and durations, which can provide a scientific basis for the cardiovascular health management of the elderly.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.
