Objective To evaluate the impact of different exercise frequencies on the symptoms,quality of life,and duration of rehabilitative effects in patients with Parkinson's disease(PD).Methods A total of 90 PD patients(Hoehn and Yahr stage ≤3,receiving continuous dopaminer-gic stimulation)admitted in Department of Neurology of Chinese PLA General Hospital were en-rolled and randomly divided into groups G1,G2 and G3,with 30 participants in each group.They received rehabilitation exercises of Parkinson's Wellness Recovery(PWR)1 h per time,at differ-ent frequencies,that is,once(G1),twice(G2)and three times(G3)a week,for totally 6 months.Unified Parkinson's disease rating scale(UPDRS),levodopa equivalent dose,10-meter walk test(10-MWT),Fullerton advanced balance(FAB)Scale,trail making test-A(TMT-A),nine-hole peg test(9-HPT)and Parkinson's disease questionare-39(PDQ-39)were applied to evaluate the efficacy of the rehabilitation.Results The PDQ-39 score was significantly decreased in all the three groups after PWR exercise(P＜0.05,P＜0.01).Compared with the corresponding levels before intervention,the group G2 had obviously lower 10-MWT score and higher FAB score(P＜0.05),and the group G3 obtained notably decreased scores in UPDRS,UPDRS-Ⅲ,10-MWT,TMT-A,9-HPT,and PDQ-39[30.72±11.31 vs 31.41±10.42,P=0.001;19.21±9.72 vs 20.17±8.80,P=0.001;7.38(6.26,8.49)s vs 7.48(6.53,8.56)s,P=0.004;53.97±8.74 s vs 54.07±8.62 s,P=0.026;38.71(33.71,49.71)s vs 38.90(33.78,49.82)s,P=0.001;28.00(14.50,36.00)vs 30.00(15.50,38.50),P=0.001],and increased FAB score[23.00(16.00,33.00)vs 21.00(16.00,32.00),P=0.005].In addition,the patients in the G3 group experienced the most pronounced re-habilitation effect immediately after exercise,but,all aforementioned indicators remained augmen-ted even 4 weeks after exercise.Conclusion Exercise rehabilitation three times weekly can greatly enhance the motor function of PD patients,ameliorate non-motor symptoms,and the overall quali-ty of life,with the beneficial effects persisting for a minimum of 4 weeks.

Objective:To develop outcome indicators for the implementation of comprehensive inter-ventions targeting the multimorbidity of myopia and obesity in children and adolescents,providing a basis for the co-prevention of multimorbidity and the outcome measurement of implementation research in children and adolescents.Methods:Based on the RE-AIM framework,a preliminary set of indicators was constructed.The Delphi method was employed,with experts scoring and providing feedback on the proposed indicators via questionnaires.After each round of consultation,expert enthusiasm index,authority coefficient,coordination degree,and consensus level were calculated.Expert opinions were col-lected and analyzed to modify,delete,or add indicators based on consultation results and screening crite-ria.Two Delphi rounds were conducted until consensus was achieved.Results:A total of 28 experts par-ticipated actually in both rounds.The Kendall's W coefficients for the two rounds of expert consultation were0.352(x2=413.952,P＜0.001)and 0.499(x2=405.044,P＜0.001),both statistically sig-nificant.The final outcome indicators for implementation research on comprehensive interventions for myopia and obesity comorbidity in children and adolescents included five primary dimensions with 13 secondary and 20 tertiary indicators.The dimension of reach included the number of children and adoles-cents involved,participant representativeness,and full-course participation representativeness.The di-mension of effectiveness included multimorbidity incidence,myopia incidence,spherical equivalent,body mass index(BMI),overweight and obesity prevalence,waist-to-height ratio,comprehensive health knowledge score,and comprehensive health behavior score.The dimension of adoption covered school representativeness and representativeness of school nurses and teachers involved in implementation.The dimension of implementation included fidelity,content modification,and cost.The dimension of mainte-nance included individual health outcomes and organizational sustainment.Conclusion:This study developed implementation outcome indicators for comprehensive interventions targeting multimorbidity of myopia and obesity among the children and adolescents based on the RE-AIM framework.These indica-tors can serve as a reference for optimizing intervention research strategies related to common multimor-bidity among children and adolescents in China.

Objective:To explore effect of information management mode of full lifecycle for medical equipment on the basis of Service-Oriented Architecture(SOA)on the information management for information management of full lifecycle in hospital.Methods:An information management mode of full lifecycle for medical equipment was adopted to conduct information management for full lifecycle of medical equipment,so as to solve a series of problems included perception for the situation of equipment,and early warning for fault,and so on.A total of 100 medical equipment in clinical use at The First Rongjun Youfu Hospital of Shandong Province from February 2023 to February 2024 were selected for the study.In them,50 equipment were managed under a continuous improvement mode,while the other 50 equipment were managed by using a SOA-based information management mode of full lifecycle(information management mode).The score of management quality for equipment,management standardization and operational quality of the two kinds of management modes were compared.A self-designed satisfaction questionnaire of using and managing equipment was used to survey the satisfactions of medical engineers,operators of equipment,and staffs of equipment department in using and managing equipment,who involved in usage and management for equipment.Results:Under the information management mode,the scores for usage of equipment,the return efficiency,safety performance,maintenance quality,cleaning quality,and overall evaluation were respectively(22.98±2.11),(23.69±1.65),(22.74±1.36),(23.65±1.54),and(93.01±4.65),all of which were significantly higher than those of the continuous improvement mode,with statistically significant differences(t=6.672,11.428,9.256,12.976,13.182,P<0.05).The standardizations of usage operation of equipment,cleaning and disinfection,safety monitoring,and quality control of adopting information management mode were higher than those of adopting continuous improvement mode(x2=13.709,11.679,11.284,15.120,P<0.05).The failure rates of surgical equipment,therapeutic equipment,diagnostic equipment,dialysis equipment,and emergency equipment of adopting information management mode were all lower than those of adopting continuous improvement mode,with statistically significant differences(x2=16.872,13.878,17.156,11.679,12.805,P<0.05).Satisfaction scores of medical engineers,operators for equipment,and staffs of equipment department of adopting information management mode were significantly higher than those of adopting the continuous improvement mode,with statistically significant differences(t=16.872,13.878,17.156,P<0.05).Conclusion:The application of a SOA-based information management mode of full lifecycle for medical equipment in management for medical equipment can enhance management level for equipment,and improve operational quality of equipment,and enhance safety and utilization efficient of using equipment.

Objective To explore the effects of glycyrrhizic polysaccharide(GP)on the biological activity of salivary adenoid cystic carcinoma tumor cells and its mechanisms of anti-tumor action.Methods GP was prepared,and human adenoid cystic carcinoma high-metastatic cell line SACC-LM and low-metastatic cell line SACC-83 were used as target cells.Different concentrations of GP were used for intervention.The cell counting kit-8(CCK-8)assay was employed to detect cell proliferation and apoptosis.Reverse transcrip-tion polymerase chain reaction(RT-PCR)and Western blot experiments were conducted to detect the expression of genes and proteins related to tumor invasion and metastasis.The scratch assay was used to observe the effect of GP on the migration ability of SACC cells.In vivo experiments were conducted to verify the inhibitory effect of GP on tumor cells.Results Glycyrrhiza polysaccharides signifi-cantly inhibited the proliferation and migration of the highly metastatic human adenoid cystic carcinoma cell line SACC-LM by regulating the expression of epithelial-mesenchymal transition(EMT)-related markers.In vivo experiments showed that glycyrrhiza poly-saccharides had no significant hepatotoxicity,could significantly reduce the volume and weight of tumors,and inhibit the growth rate of tumors in nude mice.Conclusion GP has a certain inhibitory effect on the growth and migration ability of SACC.

The esophagogastric junction serves as a natural anti-reflux barrier and possesses a complex anatomical configuration composed of several key components, including the lower esophageal sphincter, diaphragmatic crura, His angle, and phrenoesophageal ligament. Alterations in these anatomical structures or dysfunction thereof may predispose individuals to gastroesophageal reflux disease (GERD). In response to such structural and functional impairments, various therapeutic strategies have been developed. Surgical intervention is currently regarded as an effective approach for fundamentally addressing GERD, with commonly employed techniques including laparoscopic fundoplication, magnetic sphincter augmentation, and endoscopic radiofrequency ablation. The author classifies the anti-reflux mechanisms at the esophagogastric junction into intramural and extramural components, and based on this classification, systematically reviews and evaluates the indications and clinical applications of major surgical interventions for GERD, aiming to provide clinicians with evidence-based guidance for selecting appropriate therapeutic modalities.

Parkinson′s disease (PD) is a neurodegenerative disorder prevalent among the elderly, characterized by the degeneration of dopaminergic neurons in the substantia nigra. The motor symptoms of PD include resting tremor, bradykinesia, rigidity, and postural gait disturbances. Additionally, non-motor symptoms such as depression, pain, cognitive impairment, sleep disorders, and autonomic dysfunction are gaining increasing attention. Among these, bladder and urethral dysfunction is one of the most common manifestations of autonomic dysfunction and significantly impacts patients′ quality of life in the later stages of the disease. This article provides a review of recent research on the epidemiology, pathogenesis, and treatment of bladder and urethral dysfunction in PD, aiming to enhance the understanding and management of urinary symptoms associated with PD.

Objective:To evaluate the left atrial structure and function in patients with non-obstructive hypertrophic cardiomyopathy（NOHCM）and atrial fibrillation（AF）using four-dimensional automatic left atrial quantification（4D Auto LAQ）technology，and to explore the correlation between left atrial remodeling and AF.Methods:Ninety patients with NOHCM treated in the First Affiliated Hospital of Zhengzhou University from May 2023 to September 2024 were prospectively selected and divided into AF group（ n=27）and non-AF group（ n=63）according to whether they had AF. Clinical data of all enrolled patients were collected，and two-dimensional，color Doppler，and tissue Doppler ultrasound parameters were measured. 4D Auto LAQ technology was used to obtain left atrial volume and strain parameters. Inter-group comparison，univariate and multivariate Logistic regression analysis，and repeatability test were used to analyze the data. Results:Compared with non-AF group，left atrial maximum volume index（LAVImax），left atrial minimum volume index（LAVImin）and left atrial pre-systolic volume index（LAVIpreA）were increased in the AF group，but left atrial total ejection fraction（LAEF），left atrial passive ejection fraction（LApEF），left atrial active ejection fraction（LAaEF）and the absolute values of left atrial reservoir longitudinal and circumferential strains（LASr，LASr-c），left atrial conduit longitudinal and circumferential strains（LAScd，LAScd-c）and left atrial contraction longitudinal and circumferential strains（LASct，LASct-c）were decreased（all P<0.05）. Multivariate Logistic regression analysis showed that LAVImin was independently associated with AF（ OR=0.837， P<0.001）. Conclusions:4D Auto LAQ can quantitatively evaluate the left atrial structure and function in patients with NOHCM and AF，and LAVImin is independently associated with the presence of AF.

Objective:To evaluate the left atrial function in patients with hypertrophic cardiomyopathy（HCM）combined with heart failure with preserved ejection fraction（HFpEF）using four-dimensional automated left atrial quantification（4D Auto LAQ）technology，and to investigate the independent factors affecting patients with HCM combined with HFpEF.Methods:One hundred HCM patients with left ventricular ejection fraction（LVEF）≥ 50% who were admitted to the First Affiliated Hospital of Zhengzhou University from September 2023 to March 2025 were prospectively selected. There were 50 cases in the HFpEF group and 50 cases in the non-HF group. The clinical data and conventional ultrasound parameters of HCM patients were collected. The 4D Auto LAQ technology was applied to obtain the four-dimensional volume and strain parameters of the left atrium，including the minimum left atrial volume（LAVmin），the maximum left atrial volume（LAVmax），the maximum left atrial volume index（LAVImax），the pre-atrial contraction volume（LAVpreA），the left atrial emptying volume（LAEV），the left atrial ejection fraction（LAEF），the longitudinal and circumferential strains in the left atrial reservoir period（LASr，LASr-c），the longitudinal and circumferential strains in the left atrial conduit period（LAScd，LAScd-c），the longitudinal and circumferential strains in the left atrial contraction period（LASct，LASct-c），and the minimum left atrial volume index（LAVImin）. The differences in the above parameters between the two groups were compared. Univariate and multivariate Logistic regression analyses were used to analyze the independent influencing factors in HCM patients with HFpEF. The intraclass correlation coefficient was used to test the repeatability of the 4D Auto LAQ parameters.Results:Compared with the non-HF group，LAVmin，LAVmax，LAVpreA，LAVImin，and LAVImax increased，while LAEF，LASr，LAScd，LASct，LASr-c，LAScd-c，and LASct-c decreased in the HFpEF group（all P<0.05）. Multivariate Logistic regression analysis showed that LASr was the strongest independent influencing factor in patients with HCM combined with HFpEF（ OR=0.255， P=0.003）. The consistency test showed that the intraclass correlation coefficients of each parameters of 4D Auto LAQ were all>0.7，the consistency was good. Conclusions:4D Auto LAQ technology can be used to evaluate left atrial function in patients with HCM combined with HFpEF，and LASr is the strongest independent influence factor in patients with HCM combined with HFpEF.

Objective:To investigate the efficacy of lightroom therapy on depressive mood and sleep problems in patients with depression, and the potential effects on physiological indices related to circadian rhythms.Methods:From October 2021 to July 2023, 54 patients with acute-phase depression hospitalized in the Mental Health Center of the First Hospital of Hebei Medical University were recruited. The participants were randomly assigned to either medication combined with the bright light therapy group (bright light group, n=36) or medication combined with the dim light therapy group (dim light group, n=18). Both groups received light therapy for 2 weeks, at 10 000 lx in the bright light group and 300 lx in the dim light group. Both groups received 30 minutes of light therapy from 7:30-8:00 a.m daily over two weeks, followed up for 1 week post-treatment. The Hamilton Depression Rating Scale (HAMD 17) was used to assess patients′ depressive symptoms, and the Pittsburgh Sleep Quality Index (PSQI) was used to assess patients′ sleep quality at baseline, at the end of every week. The 32-Item Hypomania Checklist (HCL-32) was used at the end of week 2 to assess the risk of manic switching after treatment. Daily measurements of body temperature, heart rate, and blood pressure were taken before and after light therapy, along with recording adverse events related to the therapy. Paired t- tests were used to compare changes in physiological indicators before and after treatment, and repeated measures ANOVA was applied to compare clinical symptom changes between the two groups. Results:Thirty-one and fifteen patients completed this study in the bright light and dim light groups, respectively, with no statistically significant difference in dropout rates( P>0.05). There were significant interaction effects between the time and group for HAMD 17 and PSQI score( F=5.51,4.11, both P<0.05). Both groups showed significant reductions in HAMD 17 and PSQI scores at baseline, week 1, week 2, and week 3 ( P<0.001). In the bright light group, body temperature increased significantly post-treatment on days 1-4, day 7, and day 12 (all P<0.05). Heart rate elevated on day 5 ( P<0.05).Systolic blood pressure decreased on days 4, 5, 11, and 12 compared to the pre-treatment baseline(all P<0.05). In the dim light group, systolic blood pressure increased on day 11 ( P<0.05). Diastolic blood pressure in the bright light group decreased on days 1, 5, and 6( P<0.05). No serious adverse events, vision loss, ocular structural changes occurred in either group. No hypomania or mania episodes were observed. The incidence of adverse events did not differ significantly ( P>0.05). Conclusion:Medication combined with indoor bright light is more effective than the combination of dim light for depressive symptoms and sleep problems in patients with depression. Patients receiving bright light also may exhibit a higher body temperature, accelerated heart rate, and reduced blood pressure.
