ObjectiveTo investigate the effect of cerebellar intermittent theta-burst stimulation (iTBS) on postural control and fall risk in stroke patients. MethodsFrom October, 2024 to August, 2025, 45 stroke patients were recruited from Huadong Hospital Affiliated to Fudan University. They were randomly divided into control group (n = 15), group A (n = 15) and group B (n = 15). All the groups received conventional medication and rehabilitation. Group A was additionally administered iTBS over the ipsilesional primary motor cortex (M1), while group B received iTBS over the contralesional cerebellum, for three weeks. Before and after intervention, postural stability indexes (eyes open/closed), limits of stability, directional control score and reaction time were measured using Biodex Balance System, and they were assessed with Berg Balance Scale (BBS), Timed Up & Go Test (TUGT) and 10-meter walk test (10MWT). ResultsAfter intervention, significant group-time interaction effects were observed for eyes open/closed postural stability indexes, limits of stability, directional control score, reaction time, BBS score, TUGT and 10MWT (F > 23.487, P < 0.001). All the groups improved in all the indexes after intervention (P < 0.01). The eyes open/closed postural stability indexes, limits of stability, directional control score and reaction time were the best in group B, followed by group A, and the worst in the control group (P < 0.05), while BBS, TUGT and 10MWT were better in groups A and B than in the control group (P < 0.05). ConclusionCerebellar iTBS can effectively improve postural control disorders and reduce fall risk in stroke patients, and may be superior to M1 iTBS.

ObjectiveTo systematically evaluate the effect of intermittent theta burst stimulation (iTBS) on lower extremity motor function and balance function in patients with stroke. MethodsA systematic literature search was conducted in the Cochrane Library, Embase, PubMed, Web of Science, CNKI, SinoMed, Wanfang data and VIP from inception to February 19, 2025. Randomized controlled trials comparing iTBS with conventional rehabilitation or sham iTBS in patients with post-stroke lower extremity motor and balance dysfunction were included. The methodological quality of the included studies was assessed using the Cochrane Risk of Bias Tool. Meta-analysis was performed using RevMan 5.4 and Stata 14.0. ResultsA total of 16 articles involving 647 patients were included. Meta-analysis showed that iTBS improved the Fugl-Meyer Assessment-Lower Extremities score (MD = 2.58, 95%CI 1.61 to 3.55, P < 0.001), Berg Balance Scale score (MD = 4.11, 95%CI 2.43 to 5.79, P < 0.001), Barthel Index score (MD = 4.95, 95%CI 0.97 to 8.92, P = 0.010) and motor-evoked potential (MEP) latency (MD = -1.42, 95%CI -2.54 to -0.30, P = 0.010). Subgroup analyses suggested that at subacute stage, cerebellar iTBS, more than ten treatment sessions, and 1 200 pulses per day may be more effective. ConclusioniTBS may improve lower extremity motor function and activities of daily living in patients with stroke, and shorten MEP latency, and it may also confer potential benefits in improving balance function in these patients.

Objective:To analyze the impact of occupational health management assistance for small and micro enterprises in Suzhou on employers, exploring the assistance model for occupational health management in small and micro enterprises.Methods:From 2020 to 2022, a total of 318 small and micro enterprises with serious occupational disease hazards, weak occupational health management, and strong subjective improvement were selected as assistance objects annually by means of territorial recommendation and active registration of employers. The basic information of the enterprise and the status of occupational health management were obtained by means of questionnaire survey, archives review, workplace field investigation and occupational disease hazard factors detection. Pearson χ2 test was used to analyze the changes of occupational health management before and after helping enterprises. Results:The small and micro enterprises receiving assistance were mainly private enterprises (51.26%, 163/318) and limited liability companies (27.99%, 89/318). The occupational health training rates for enterprise leaders, management personnel, and workers increased from 77.36% (246/318), 82.08% (261/318) and 72.44% (4554/6287) before assistance to 90.57% (288/318), 95.28% (303/318) and 94.40% (5905/6255), the differences were statistically significant ( χ2=20.60, 27.63, 1092.67, all P<0.001). After the assistance, the distribution and wearing of personal protective equipment for workers, the detection of occupational hazard factors in the workplace and occupational health examination by enterprises increased by 3.34%, 18.39%, 13.21% and 15.10%, respectively. In terms of occupational health management, the comprehensive establishment rate of occupational health management system increased from 21.70% (69/318) before assistance to 64.47% (205/318). Compared with before assistance, the comprehensive notification rate/setting rate of warning signs and notification cards, labor contracts for occupational disease hazard positions, occupational health bulletin boards, and occupational health examination results were significantly increased after assistance ( χ2=120.08, 77.40, 149.18, 86.76, all P<0.001) . Conclusion:Suzhou adopts a model led by the health administrative department and supported by technical support from service institutions to assist small and micro enterprises, resulting in a significant improvement in the occupational health management level of small and micro enterprises.

Objective:To explore the medication adherence of elderly patients with chronic diseases and polypharmacy in rural areas of Hangzhou City and analyze its influencing factors.Methods:From April to July 2023, convenience sampling was used to select rural 240 elderly patients with chronic diseases and polypharmacy in five administrative districts (counties) of Hangzhou as participants. The survey was conducted using the General Information Questionnaire, Social Support Rating Scale, Medication Knowledge and Beliefs Questionnaire, and the Chinese version of the 8-item Morisky Medication Adherence Scale. Multiple linear regression was used to analyze the factors influencing medication adherence in elderly patients with chronic diseases and polypharmacy in rural areas of Hangzhou City.Results:A total of 240 questionnaires were distributed and 220 valid questionnaires were collected, with an effective response rate of 91.67%. Among 220 elderly patients with chronic diseases and polypharmacy in rural areas of Hangzhou City, 135 had poor medication adherence. Multiple linear regression analysis showed that age, educational level, family doctor contract, medication knowledge, and beliefs were the influencing factors of medication adherence in elderly patients with chronic diseases and polypharmacy in rural areas of Hangzhou City ( P<0.05) . Conclusions:The medication adherence of elderly patients with chronic diseases and polypharmacy in rural areas of Hangzhou urgently needs to be improved. Medical and nursing staff should pay special attention to patients who are old, have a low level of education, have not signed a family doctor, and have poor knowledge and beliefs about medication. It is suggested that the contract system for family doctors be further promoted, focusing on health education on medication knowledge and beliefs, to improve medication adherence among elderly chronic disease patients in rural areas.

Sensorineural hearing loss (SNHL) is recognized as the most severe ototoxic complication following radiotherapy or chemoradiotherapy in patients with head and neck cancers (HNCs). It significantly impairs patients′ quality of life due to the lack of effective drugs. Although advances in radiotherapy techniques have played a crucial role in improving patients′ survival rates and protecting organs at risk, SNHL remains inevitable. This review presents the diagnosis, differential diagnosis, clinical manifestations, assessment criteria, pathogenesis, risk factors, and prophylactic/therapeutic strategies of SNHL, in order to provide novel insights for clinical diagnosis, treatment, and prevention.

Objective To investigate the expression of exosomal α-synuclein(α-syn),serum lipocalcitin-2(LCN-2)levels and the relationship with disease severity in Parkinson's disease(PD)patients.Methods 106 PD patients admitted to Yulin Hospital,the First Affiliated Hospital of Xi'an Jiaotong University,from June 2020 to June 2023 were selected.The PD patients were divided into the early group(n=31),the middle group(n=45)and the late group(n=30)according to their conditions,and 92 healthy volunteers who had outpatient medical checkups during the same period were selected as the control group.The exosome α-syn and serum LCN-2 levels were detected,and the differences in exosome α-syn and serum LCN-2 levels were compared in PD patients with different disease severity levels.Factors affecting the prevalence of PD and the value of exosomal α-syn and serum LCN-2 in diagnosing PD were analyzed.Results The levels of exosomal α-syn(3 086.23±359.46 pg/ml)and serum LCN-2(4.92±1.32ng/ml)in the PD group were higher than those in the control group(1 993.24±244.35 pg/ml,1.96±0.34 ng/ml),and the differences were statistically significant(t=24.636,20.909,all P<0.05).The levels of exosomal α-syn(3 312.72±53.46pg/ml)and serum LCN-2(5.76±0.28ng/ml)in the late-stage group were higher than those in the early-stage(2 843.65±65.29pg/ml,4.02±0.32ng/ml)and the middle-stage group(3 102.35±105.48pg/ml,4.98±0.41ng/ml),and the differences were statistically significant(t=9.092～30.644,all P<0.05).Family history of PD,high level of exosomal α-syn and high level of LCN-2 were the risk factors for the development of PD(Wald χ2=8.121,7.002,4.805,all P<0.05).The AUC(95%CI)of diagnosing PD with serum LCN-2 in combination with exosome α-syn was higher than that of exosome α-syn,while serum LCN-2 alone was used for diagnosis(Z=4.869,5.103,all P<0.05).Conclusion Serum exosomal α-syn and serum LCN-2 levels are significantly higher in PD patients,which can be associated with the exacerbation of PD,and combined exosomal α-syn and serum LCN-2 can assess the risk of developing PD.

Objective To develop a risk prediction model for ischemic stroke in symptomatic intracranial atherosclerotic stenosis(ICAS)patients based on high-resolution magnetic resonance imaging(HR-MRI)and arterial spin labeling(ASL)imaging.Methods A total of 142 patients were included and divided into acute ischemic stroke(AIS)and transient ischemic attack(TIA)groups based on stroke occurrence.Clinical risk factors,plaque characteristics,and arterial transit artifact(ATA)presence on ASL images were compared between the two groups.Multivariate logistic regression analysis was performed,incorporating clinical risk factors,plaque characteristics,and double post labeling delay(PLD)ATA presence.The predictive value of different models was compared using receiver operating characteristic(ROC)curve and DeLong tests.Results Hypertension,positive lumen remodeling,plaque enhance-ment rate,1.5 s-ATA presence,and 2.5 s-ATA presence were independent risk factors for AIS(P＜0.05).The combination of HR-MRI and ASL imaging predicted AIS most effectively[area under the curve(AUC)=0.908;95％ confidence interval(CI)0.862-0.954].No significant difference was found between the prediction performances of HR-MRI and ASL(95％CI-0.041-0.082,Z=0.659,P=0.509).Conclusion ASL is more convenient than HR-MRI for predicting ischemic stroke in ICAS patients.A model combining plaque characteristics and ATA presence effectively predicts AIS occurrence.

Objective To investigate the protective effect of carvacrol(CAR)on high glucose(HG)-induced retinal ganglion cell(RGC)damage by regulating the protein kinase B(PKB,also known as Akt)/nuclear factor erythroid 2-relat-ed factor 2(Nrf2)signaling pathway.Methods The RGC-5 cells in the logarithmic growth phase were inoculated into 96-well cell culture plates with 4 × 104 cells/well and then treated with CAR(5.0 μmol·L-1,10.0 μmol·L-1,20.0 μmol·L-1,40.0 μmol·L-1,80.0 μmol·L-1,and 160.0 μmol·L-1)together with 30.0 mmol·L-1 glucose for 24 hours.Cell viability was detected by the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay to screen the ex-perimental concentration of CAR.Then,these RGC-5 cells were inoculated into 6-well plates and randomly assigned into the Control group,30.0 mmol·L-1 glucose(HG)group,low-,medium-,and high-concentration CAR groups(CAR-L group,CAR-M group,and CAR-H group),and high-concentration CAR+Nrf2 pathway inhibitor(ML385)group(CAR-H+ML385 group).Flow cytometry was used to detect the apoptosis of RGC-5 cells.The fluorescent probe was used to de-tect the level of oxidative stress in RGC-5 cells.The enzyme-linked immunosorbent assay(ELISA)was employed to detect the level of superoxide dismutase(SOD),lactate dehydrogenase(LDH),malondialdehyde(MDA),glutathione peroxidase(GSH-PX),and reactive oxygen species(ROS)in the supernatant of RGC-5 cells.Western blot was used to detect the ex-pression of proteins related to the Akt/Nrf2 signaling pathway.Results Compared with the HG group,the survival rate of RGC-5 cells increased significantly when the concentration of CAR was above 20.0 μmol·L-1(all P＜0.05).Therefore,20.0 μmol·L-1,40.0 μmol·L-1,and 80.0 μmol·L-1 of CAR were used for subsequent experiments.Compared with the Control group,the apoptosis rate of RGC-5 cells in the HG group increased significantly,the protein expression of Bax and Caspase-3 was up-regulated significantly,the level of interleukin-1β(IL-1β),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),ROS,LDH,and MDA increased significantly,and the level of SOD and GSH-PX decreased significantly(all P＜0.05).Compared with the HG group,the apoptosis rate of RGC-5 cells in the CAR-L,CAR-M,and CAR-H groups de-creased significantly,the protein expression of Bax and Caspase-3 was down-regulated significantly,the level of IL-1β,IL-6,TNF-α,ROS,LDH,and MDA decreased significantly,and the level of SOD and GSH-PX increased significantly(all P＜0.05).Compared with the CAR-H group,the apoptosis rate of RGC-5 cells in the CAR-H+ML385 group increased signifi-cantly,the protein expression of Bax and Caspase-3 was up-regulated significantly,the level of IL-1β,IL-6,TNF-α,ROS,LDH,and MDA increased significantly,and the level of GSH-PX and SOD decreased significantly(all P＜0.05).Compared with the Control group,the p-Akt/Akt expression ratio and the relative expression level of Nrf2 in RGC-5 cells decreased significantly in the HG group(both P＜0.05).Compared with the HG group,the p-Akt/Akt expression ratio and the rela-tive expression level of Nrf2 in RGC-5 cells increased significantly in the CAR-L,CAR-M,and CAR-H groups(all P＜0.05).Compared with the CAR-H group,the p-Akt/Akt expression ratio and the relative expression level of Nrf2 decreased signifi-cantly in the CAR-H+ML385 group(both P＜0.05).Conclusion CAR may reduce the inflammatory response level in RGC-5 cells by activating the Akt/Nrf2 signaling pathway,thus inhibiting oxidative stress-related injury and apoptosis.
