OBJECTIVE To investigate the effects of osthole （OST） on skin wound healing and angiogenesis in rats by regulating the sonic hedgehog （SHH） signaling pathway. METHODS Full-layer skin defect wound model rats were established and then randomly separated into Model group， OST low-dose， medium-dose and high-dose groups （OST-L group， OST-M group， OST-H group， 20， 30， 40 mg/kg OST）， high-dose OST+SHH inhibitor cyclopamide group （OST-H+cyclopamide group， 40 mg/kg OST+10 mg/kg cyclopamide）， with 12 rats in each group. Another 12 rats were selected as the control group. The wound healing of rats on 1， 7 and 14 days of administration was observed， and the wound healing rate of rats in each group was measured. The pathological changes and collagen deposition in rat wound tissue were observed； the levels of angiopoietin-1 （Ang-1） and basic fibroblast growth factor （bFGF） in wound tissue of rats were detected； the relative expressions of vascular endothelial growth factor A （VEGFA） and vascular endothelial growth factor receptor-2 （VEGFR-2） mRNA were also detected in wound tissue of rats； the protein expressions of VEGFA， VEGFR-2， SHH and glioma-associated oncogene homolog-1 （GLI1） were determined in wound tissue of rats. RESULTS Compared with Model group， the healing rate of skin wound， relative expression of collagen protein， the levels of Ang-1 and bFGF， the mRNA and protein expressions of VEGFA and VEGFR-2， and the protein expressions of SHH and GLI1 were all significantly increased in OST-M and OST-H groups （P＜0.05）. The wound tissue underwent significant re- epithelialization， with reduced inflammatory cell infiltration and granulation tissue edema， and an increase in the number of new blood vessels. SHH inhibitor cycloparamide weakened the promoting effects of OST on skin wound healing and angiogenesis in rats. CONCLUSIONS OST may promote skin wound healing and angiogenesis in rats by activating the SHH signaling pathway.

ObjectiveTo evaluate the clinical efficacy and safety of acupuncture combined with levodopa in the treatment of Parkinson's disease（PD）. MethodsA total of 60 patients with PD were enrolled and randomly assigned to test group or control group， with 30 patients in each group. The control group received levodopa only， starting at 100 mg per dose， three times daily， with gradual increases not exceeding a maximum daily dose of 800 mg. The test group received acupuncture three times per week in addition to levodopa. Both groups were treated for 12 weeks. Assessments were conducted before treatment， after 6 and 12 weeks treatment， using the Unified Parkinson's Disease Rating Scale（UPDRS）， Wearing-Off Questionnaire-9（WOQ-9）， Montreal Cognitive Assessment（MoCA）， Mini-Mental State Examination（MMSE）， Depression Rating Scale（DRS）， Hamilton Depression Scale（HAMD）， Hamilton Anxiety Scale（HAMA）， PD Questionnaire-39（PDQ-39）， and Pittsburgh Sleep Quality Index（PSQI）. Repeated measures ANOVA was utilized to evaluate the effects of time， group， and their interaction on each index. Spearman correlation analysis was conducted to examine the relationships between combined treatment and outcome scores. Adverse events in both groups were recorded throughout the study. ResultsBoth groups showed significant improvements after 6 and 12 weeks treatment， with decreases in UPDRS total score， WOQ-9 total score， DRS score， HAMD score， HAMA score， PDQ-39 score， and PSQI score， and increases in MoCA and MMSE scores（P＜0.05）. Compared with the control group， the test group demonstrated significantly greater improvements in all the above indicators after 6 and 12 weeks （P＜0.05）. Repeated measures ANOVA showed significant time main effects， group main effects， and their interaction across all outcome measures（P＜0.01）. Spearman correlation analysis revealed that combined therapy was significantly negatively correlated with UPDRS， WOQ-9， DRS， HAMD， HAMA， PDQ-39， and PSQI scores， while positively correlated with MoCA and MMSE scores after 12 weeks of treatment（P＜0.05）. Both groups did not experience any serious adverse events and did not affect treatment. ConclusionAcupuncture combined with levodopa is more effective than levodopa alone in improving motor function， non-motor symptoms， cognitive function， depression and anxiety， quality of life， and sleep quality in patients with PD， with good safety.

Objective: To explore the independent and interactive effects of school green space exposure and outdoor activity duration on screening myopia among primary and secondary school students, so as to provide theoretical support for the prevention and control of screening myopia in children and adolescents. Methods: From September to November 2023, 117 487 primary and secondary school students from 497 schools were selected using a cluster random sampling method, covering 98 counties (cities, districts) in Jiangsu Province. Data on the students screening myopia status and associated health influencing factors were collected and analyzed. School green space exposure was quantified using the normalized difference vegetation index (NDVI), which was extracted with ArcGIS Pro software; meanwhile, information on students outdoor activity duration was gathered through self reported questionnaires. Multivariate Logistic regression was applied to assess the independent and interactive effects of green space exposure and outdoor activity duration on screening myopia among primary and secondary school students. Results: Univariate analysis showed that there were statistically significant differences in screening myopia detection rates among primary and secondary school students of different genders, NDVI groups, every outdoor activity duration, monitoring points, school stages, parents educational level, and whether they lived on campus or had parents with screening myopia ( χ 2=88.91-1 950.08, all P <0.05); as the school age and sedentary time increased, the detection rate of screening myopia in primary and secondary school students also increased ( χ 2 trend =8 410.15, 2 028.91, both P <0.05). Independent effects showed that compared to the low NDVI group, the medium and high NDVI groups had lower risks of screening myopia ( OR =0.93, 0.95, both P <0.05). Compared to those with outdoor activity duration<2 h/d, students with outdoor activity duration≥2 h/d had a lower risk of screening myopia ( OR =0.96, P <0.05). When stratified by school level, compared to the low NDVI group, the medium NDVI group had lower risks of screening myopia in primary and junior high schools (primary school: OR =0.91; junior high school: OR =0.88, both P <0.05). Compared to those with outdoor activity duration<2 h/d, junior high school students with outdoor activity duration≥2 h/d had a lower risk of screening myopia ( OR = 0.90, P <0.05). When stratified by monitoring site, urban primary and secondary school students in the medium and high NDVI groups and those with outdoor activity duration≥2 h/d had lower risks of screening myopia ( OR =0.92, 0.92, 0.93, all P <0.05). Interactive effects showed that when medium or high NDVI was combined with outdoor activity duration≥2 h/d, the risks of screening myopia among primary and secondary school students were lower (medium NDVI×≥2 h/d: OR =0.89; high NDVI×≥ 2 h/d : OR =0.89, both P <0.05), and the combined effect was superior to that of a single factor. Conclusion Green space exposure and outdoor activity duration have negative correlations with screening myopia among primary and secondary students, and the combined effect is better than that of a single factor.

Objective: To investigate the association between outdoor light at night (LAN) exposure and sleep quality among primary and secondary school students, and to examine the pathways of negative affects including depressive, stress and anxiety symptoms, so as to provide a theoretical basis for optimizing the school environment and enhancing the physical and mental well being of students. Methods: In December 2024, a total of 36 885 students from 154 primary and secondary schools in Suzhou, Nantong, and Changzhou were included via a stratified cluster sampling method. Sleep quality and negative affect were assessed by using the Pittsburgh Sleep Quality Index (PSQI), Center for Epidemiologic Studies Depression Scale (CES-D), Generalized Anxiety Disorder-7 (GAD-7), and Depression, Anxiety and Stress Scale-21 (DASS-21), respectively. Outdoor LAN exposure data were obtained from the national polar orbiting partnership visible infrared imaging radiometer suite nighttime light(NPP-VIIRS NTL) dataset provided by the National Earth System Science Data Center. Multivariate Logistic regression model was employed to analyze the association between LAN exposure and sleep quality across different regions, with stratification by monitoring site. Spearman correlation analysis was used to examine the relationships between LAN, negative affect, and sleep quality. The mediating role of negative affect was tested by using Model 4 of the PROCESS macro. Results: The detection rates among students were 13.95%( n =5 147) for depressive symptom, 16.72%( n =6 166) for stress symptom, and 17.49%( n =6 451) for anxiety symptom. The median outdoor LAN exposure was 28.85(19.10, 41.44)nW/(cm 2 · ( sr). After adjusting for confounders, multivariate Logistic regression analysis showed that high LAN exposure ( Q 4) was positively associated with sleep problems (urban areas: OR =1.28, 95% CI = 1.17- 1.41; rural areas: OR =1.21, 95% CI =1.07-1.36; both P <0.05). Spearman correlation analysis revealed significant positive correlations between LAN exposure, depressive symptoms, stress symptoms, anxiety symptoms, and sleep quality ( r =0.03-0.75, all P < 0.01). The mediation analysis indicated that all dimensions of negative affect significantly mediated the relationship between high LAN exposure and poor sleep quality (all P <0.01). Specifically, the indirect effects were 0.03 (95% CI =0.02-0.05) for depressive symptom, 0.05(95% CI =0.03-0.08) for stress symptom, and 0.07(95% CI =0.05-0.09) for anxiety symptom. Overall, 31.9% of the total effect was mediated by negative affect, with anxiety (14.89%) being the strongest mediator, followed by stress (10.64%) and depression(6.38%). Conclusion Reducing high levels of outdoor LAN exposure and implementing interventions targeting negative affect may contribute to improved sleep quality among primary and secondary school students.

Objective: To assess the effectiveness of online and offline myopia prevention and control health education interventions using wearable behavior monitoring tools for non myopic elementary school students,so as to provide evidence based medical support for public health practices. Methods: From May to June in 2021, two schools were selected within the same county in Jiangsu Province. School 1 conducted online and offline parental health education ( n =111), while school 2 exclusively conducted offline health education activities, representing the traditional intervention group ( n =122). Students from both schools underwent monitoring through wearable behavior tracking tools, with feedback reports provided (eye distance, eye duration, ambient light, and outdoor exposure time). Both schools relied on activities to carry out health education interventions, and organized the distribution of promotional materials and display boards. The intervention group also established WeChat groups to conduct online "Healthy Parents Action" (answering and providing feedback on health knowledge related to myopia prevention and control, myopia prevention and control, science popularization, etc. raised by parents). Evaluation criteria included myopia rates, post dilation refractive error, and axial length, with a tracking period of two years (from 2021 to 2023). Additionally, the study collected refractive parameters from non myopic students who did not participate in wearable tool monitoring in the 12 classes across the two schools. Results: The baseline results indicated that there were no significant differences between the two groups in terms of refractive parameters and wearable tool monitoring results (including screen time, viewing distance, outdoor exposure time, and homework light exposure)( t/Z/χ 2=1.94,1.17,0.58,0.40,0.80,0.69,0.32, P >0.05). After a two-year follow up, in the first and second year, the myopia rate of the online Healthy Parents Action group (11.4%, 29.7%) were lower than that of the traditional group (26.2%, 50.9%), and the degree of refractive change in the intervention group [0.63(0.38,1.19)D] was lower than that of the traditional group [0.91(0.40,1.50)D], and all the differences were statistically significant( χ 2/ Z =4.93，10.37，2.29， P <0.05). However, there were no significant differences ( P >0.05) in axial length changes between the two groups over the twoyear intervention period. Nevertheless, in the second year, the axial length change in the traditional group [0.35(0.20,0.65)mm] was lower than that in the natural observation group [0.55(0.30,0.75)mm], and this difference was statistically significant ( Z =1.92, P <0.05). Conclusions Online and offline myopia prevention and control health education can effectively reduce myopia rates. The intervention mode combining wearable behavior monitoring tools with online health education may have better effects, but further large sample and multi center studies are needed to provide additional evidence and confirmation.

Objective: To explore the influencing factors of exposure to campus bullying among junior and senior school students, and to establish a column line diagram model for risk prediction, while providing a theoretical basis for campus bullying prevention and control in secondary schools. Methods: A total of 22 034 junior and senior school students were selected via direct sampling technique from September to November 2021 in 13 cities in Jiangsu Province, China, and questionnaires were administered using the Student Health Behavior Questionnaire. The Chi squared test and multifactor Logistic regression analysis were used to derive the influencing factors of exposure to campus bullying, and a column line graph prediction model was drawn. Results: A total of 540 students reported that they had experienced campus bullying, with a prevalence rate of 2.45%. Being in a non conventional family ( OR =1.30,95% CI =1.02-1.65), overweight/obesity ( OR =1.35,95% CI =1.09-1.67), scolding by parents in the past 30 days ( OR =2.27,95% CI =1.82-2.84), cigarette smoking in the past 30 days ( OR =1.54,95% CI =1.11-2.15), Internet addiction ( OR =2.03，95% CI =1.34-3.08), and depressive symptoms( OR =5.24，95% CI =4.16-6.61), all of which were positively correlated with exposure to campus bullying among junior and senior school students ( P <0.05). Furthermore, the following factors were negatively associated with junior and senior school students protection from campus bullying in female students ( OR = 0.58 , 95% CI =0.46-0.72)，senior school students ( OR =0.68，95% CI =0.54-0.83), eating breakfast sometimes ( OR =0.37，95% CI = 0.22 -0.62), and eating breakfast everyday ( OR =0.28，95% CI =0.17-0.49) ( P <0.05). The column line graph established based on the above influencing factors had an area under the curve of 0.792 (95% CI =0.769-0.815), and the calibration curve showed that the predicted value was basically the same as the measured value. Conclusions Non conventional families, overweight/obesity, male students, junior school students, scolding by parents, cigarette smoking, Internet addiction, and depressive symptoms are correlated with school bullying among middle school students. The predictive model constructed in the study can provide an effective basis to predict the risk of school bullying and facilitate the implementation of proactive interventions for junior and senior school students.

Objective:To investigate the relationship between serum glial cell line-derived neurotrophic factor (GDNF) levels and neuroimaging changes and cognitive impairment in patients with cerebral small vascular disease (CSVD).Methods:135 patients with CSVD recruited from the Department of Neurology of the First Affiliated Hospital of Xinxiang Medical University from September 2021 to July 2022 were assessed by cranial multimodal magnetic resonance imaging and Montreal cognitive function assessment (MoCA), and the basic data were analyzed at the same time.The serum GDNF concentration of all patients was detected by enzyme-linked immunosorbent assay (ELISA). According to the median GDNF concentration, the patients were divided into low GDNF group and high GDNF group. The baseline data, MoCA score and imaging markers of the two groups were compared by Mann-Whitney U test, chi-square test, logistic regression, Kruskal-Wallis H test and Jonckheere-Terpstra trend test, and the correlation between serum GDNF level and imaging markers and cognitive function of patients with CSVD was analyzed. Results:The median serum GDNF concentration of all CSVD patients was 16.66 pg/mL. Multivariate logistic regression analysis showed that low serum GDNF level was a risk factor for white matter hyperintensity and total image load in patients with CSVD. Serum GDNF level was a protective factor of cognitive impairment in patients with CSVD in multiple logistic regression analysis. The area under the curve of ROC curve analysis of cognitive impairment after CSVD predicted by serum GDNF level was 0.735, the sensitivity was 66.4%, and the specificity was 71.4%. The level of serum GDNF was positively related with visual space and executive function, attention and computational power, delayed recall and orientation( r=0.267, 0.187, 0.219, 0.215, all P<0.05). Conclusion:The serum GDNF level is related to white matter hyperintensities, total imaging load and cognitive impairment in patients with CSVD. Serum GDNF level may play a predictive role in CSVD and cognitive impairment.

Objective:To investigate the effects of Danggui Shaoyao San(DSS) on cognitive function and neuronal apoptosis in vascular dementia (VD) rats.Methods:Fifty SPF grade male SD rats aged 6-7 weeks were randomly divided into sham operation group, model group, positive drug group (nimodipine group, 9.45 mg·kg -1), DSS low-dose group (1.6 g·kg -1), DSS high-dose group (6.4 g·kg -1) according to random number table, with 10 rats in each group. The VD rat model was established by permanent ligation of bilateral common carotid arteries. Seven days after modeling, the rats in different groups were administrated by gavage according to corresponding interventions, once a day, for 28 days. Morris water maze test was used to evaluate the learning and memory ability of rats.The levels of malondialdehyde (MDA), superoxide dismutase (SOD) and reactive oxygen species (ROS) in hippocampal area of rat brain were detected by ELISA.The protein expressions of apoptosis-related proteins Bcl-2, Bax, cleaved Caspase-3 and leptin receptor/glycogen synthase kinase 3β microtubule-associated protein tau(LEP-R/GSK-3β/tau) signaling pathway were detected by Western blot. GraphPad Prism 9 software was used for statistical analysis of data, repeated measure ANOVA and one-way ANOVA were used for comparison between multiple groups, and SNK- q test was used for further pairwise comparison. Results:The results of water maze experiment showed that the time and group interaction of escape latency of the five groups were not significant ( F=1.223, P>0.05), the main effect of group and time were significant ( F=74.65, 18.32, both P<0.05). On the 5th day, the escape latency of nimodipine group, DSS low-dose group and DSS high-dose group were lower than that of model group ( q=14.425, 7.477, 21.392, all P<0.05), and that of DSS high-dose group was lower than that of nimodipine group ((15.28±2.46)s, (22.78±3.31)s, q=6.966, P<0.05). There was statistically significant difference in the number of crossing platforms of rats in 5 groups ( F=17.331, P<0.05). The numbers of platform crossing in nimodipine group and DSS high-dose group were higher than that in model group ( q=6.789, 10.635, 5.270, all P<0.05), and the number of platform crossing in DSS high-dose group was higher than that in nimodipine group ((6.84±1.63), (5.22±1.75), q=3.846, P<0.05). ELISA results showed that the levels of MDA, ROS and SOD in hippocampal tissues of rats in 5 groups were significantly different ( F=49.338, 38.518, 15.440, all P<0.05). The levels of MDA and ROS in hippocampus of DSS high-dose group were lower than those of model group ( q=16.061, 13.541, both P<0.05) and nimodipine group ( q=4.317, 5.162, both P<0.05), SOD level of DSS high-dose group was higher than those of model group ( q=8.179, P<0.05) and nimodipine group ( q=4.135, P<0.05). Western blot results showed that the levels of apoptosis-related proteins Bcl-2/Bax and Caspase-3 were significantly different in the 5 groups ( F=30.692, 43.384, both P<0.01). The level of Bcl-2/Bax in DSS high-dose group was higher than that in model group ( q=10.562, P<0.05) and nimodipine group ( q=3.820, P<0.05), the level of Caspase-3 was lower than those of model group ( q=12.139, P<0.05) and nimodipine group ( q=7.734, P<0.05). The levels of LEP-R, p-GSK-3β, p-S404 tau and p-S202 tau expression level in hippocampal tissues of the 5 group were significantly different ( F=80.927, 59.230, 159.784, 105.923, all P<0.01). The levels of LEP-R and p-GSK-3β protein in nimodpine group and DSS high-dose group were higher than those in model group ( q=16.275, 20.104, both P<0.05; q=12.942, 17.257, both P<0.05), the levels of p-S404 Tau and p-S202 Tau in the two groups were lower than those in model group ( q=19.121, 27.456, both P<0.05; q=17.559, 22.780, both P<0.05). The levels of LEP-R(0.98±0.15), (0.86±0.14)) and p-GSK-3β((0.95±0.16)s, (0.82±0.13)) in DSS high-dose group were higher than those in nimodipine group ( q=3.829, 4.314, both P<0.05), the levels of p-S404 Tau((0.41±0.03)s, (0.58±0.07)) and p-S202 Tau((0.48±0.05)s, (0.59±0.06)) in DSS high-dose group were lower than those of nimodipine group ( q=8.335, 5.220, both P<0.05). Conclusion:DSS can improve the cognitive function of VD rats, and the mechanism may be related with reducing oxidative stress level, inhibiting neuronal apoptosis, and upregulating LEP-R/GSK-3β/Tau signaling pathway.
