ObjectiveTo investigate the current status of assistive device use and unmet needs among persons with disabilities in Sichuan-Chongqing region, and to identify the key factors associated with satisfaction with these devices. MethodsFrom October, 2024 to February, 2025, quota sampling was adopted to recruit 1 040 persons with disabilities in Sichuan and 260 persons with disabilities in Chongqing. Telephone and online questionnaires were used to collect data on demographic characteristics, status of assistive device utilization and unmet assistive device needs, as well as satisfaction with assistive device use. Correlation analysis, multiple linear regression analysis and structural equation modeling were performed to identify key factors associated with satisfaction. ResultsA total of 1 186 valid responses were collected, of which 942 were from Sichuan Province and 244 from Chongqing Municipality. The utilization rate of assistive devices among persons with disabilities in Sichuan-Chongqing region was 61.9%, and the rate of unmet assistive device needs was 30.6%. The assistive device utilization rate of participants with agricultural household registration (57.98%) was lower than that of participants with non-agricultural household registration (66.86%). The utilization rate showed a J-shaped upward trend with the increase of educational attainment. Educational attainment (P = 0.002), perceived usefulness of assistive devices (P < 0.001), home living environment (P < 0.001), public environment (P < 0.001) and disability type (significant differences were found in visual and hearing disabilities compared with physical disability, P < 0.05) were key predictors of satisfaction with assistive device use. The impact of public environment on satisfaction was exerted through two indirect mediating paths: mediating effect via perceived usefulness of assistive devices (ind₁ = 0.357, 95%CI 0.279 to 0.437, P < 0.001), contributing approximately 70% of the total indirect effect; mediating effect via home living environment (ind₂ = 0.129, 95%CI 0.006 to 0.242, P = 0.038), contributing approximately 25% of the total indirect effect. ConclusionThere is a structural imbalance between assistive device use and demand in Sichuan-Chongqing region. People with psycho-intellectual disabilities are most likely to be excluded from the service chain because they neither perceive need nor access information. Education exerts a robust positive effect on both adoption and satisfaction, so training content must be tailored to different educational levels. Satisfaction is shaped by disability type, device usefulness and environmental factors. Future product development should therefore integrate functional and psychosocial dimensions. Priority should be given to micro-scale home-and-community accessibility retrofits before extending upward to public transportation and employment settings, to maximize the cost-effectiveness of limited funds.

Objective To investigate the relationship between serum trimethylamine oxide(TMAO),endo-thelial cell specific molecule 1(Endocan)and cardiac function and pregnancy outcome in patients with hyper-tensive disorders of pregnancy(HDP).Methods A total of 182 patients with HDP admitted to Handan Ma-ternal and Child Health Hospital from January 2021 to June 2023(HDP group)and 98 healthy pregnant women admitted to this hospital during the same period(control group)were selected as research subjects.Serum TMAO,Endocan and left ventricular cardiac function indexes[left ventricular ejection fraction(LVEF),left ventricular end-diastolic volume(LVEDV)and left ventricular end-systolic volume(LVESV)]were compared between the two groups.According to pregnancy outcome,HDP patients were divided into poor outcome group(78 cases)and good outcome group(104 cases).Spearman correlation analysis was used to analyze the correlation between serum TMAO and Endocan and cardiac function indexes in HDP patients,and multi-factor Logistic regression was used to analyze the influencing factors of adverse pregnancy outcomes in HDP patients.The predictive value of serum TMAO and Endocan for adverse pregnancy outcomes in HDP patients was analyzed by receiver operating characteristic(ROC)curve.Results Compared with control group,serum TMAO,Endocan,LVEDV and LVESV were increased in HDP group,and LVEF was decreased(P＜0.05).Serum TMAO and Endocan in HDP patients were negatively correlated with LVEF(P＜0.05),and positively correlated with LVEDV and LVESV(P＜0.05).The incidence of adverse pregnancy outcomes in 182 HDP patients was 42.86％(78/182).Preeclampsia(PE),severe preeclampsia(SPE),24 h urine protein increase,LVEDV increase,LVESV increase,TMAO increase,Endocan increase were independent risk factors for adverse pregnancy outcomes in HDP patients,and LVEF increase was protective factor(P＜0.05).The area under the curve of serum TMAO combined with Endocan in predicting adverse pregnancy outcomes in HDP patients was 0.880,which was greater than 0.793 and 0.788 predicted by serum TMAO and Endocan a-lone.Conclusion The increase of serum TMAO and Endocan levels in HDP patients are relate to the decrease of cardiac function and adverse pregnancy outcomes,and the combined detection of the two has high predictive value for adverse pregnancy outcomes in HDP patients.

Objective To investigate the expression levels of peroxisome proliferator-activated receptor gamma coactivator-1β(PGC-1β),hypoxia-inducible factor-1α(HIF-1α),and resistin(RETN)in gouty arthri-tis(GA),and analyze their correlation with the degree of joint damage.Methods A total of 134 patients with GA in the hospital from January 2022 to October 2023 were selected as GA group,and 134 healthy people who underwent the physical examination in the same period were selected as control group.The serum expression levels of PGC-1β,HIF-1α and Retn were compared between the two groups.The expression levels of PGC-1β,HIF-1α and Retn in serum and synovial fluid of patients with different clinical characteristics in GA group were compared,the degree of joint destruction was graded according to the subjective pain grading method(VAS)and the patients were divided into a severe GA subgroup of 78 cases and a mild GA subgroup of 56 ca-ses.The expression levels of PGC-1β,HIF-1α,RETN,bone destruction factors[β-cross linked degradation products(β-CTX),tartrate resistant acid phosphatase-5b(TRACP5b),receptor activator of nuclear factor kappa B ligand(RANKL)]and inflammatory factors[tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)]were compared among different degrees of joint destruction,and the correlation between serum and syno-vial fluid PGC-1β,HIF-1α,RETN and the degree of joint destruction,bone destruction factors,and inflamma-tory factors was analyzed.Results The expression level of PGC-1β in serum of GA group was lower than that of the control group,while the expression levels of HIF-1α and RETN in serum were higher than those of the control group(P＜0.05).There were statistically significant differences in serum and synovial fluid PGC-1β,HIF-1α,and RETN levels among GA patients with different clinical stages,affected joints,disease duration,and annual seizure frequency(P＜0.05).The expression levels of PGC-1β in the serum and synovial fluid of the severe GA subgroup were lower than those of the mild GA subgroup(P＜0.05),while the expression lev-els of HIF-1α and RETN were higher than those of the mild GA subgroup(P＜0.05).The expression levels ofβ-CTX and TRACP5b in the severe GA subgroup were higher than those in the mild GA subgroup(P＜0.05),while the expression level of RANKL was lower than that in the mild GA subgroup(P＜0.05).PGC-1βin serum and synovial fluid was negatively correlated with the degree of joint destruction,β-CTX,TRACP5b,TNF-α,and IL-1β,and positively correlated with RANKL.HIF-1α and RETN were positively correlated with the degree of joint destruction,β-CTX,TRACP5b,TNF-α,and IL-1β,and negatively correlated with RANKL.Conclusion PGC-1β,HIF-1α,and RETN are abnormally expressed in patients with GA,and are closely associ-ated with the degree of joint destruction,bone destruction factors,and inflammatory factors.They are expec-ted to become reliable indicators for evaluating the occurrence and progression of GA.

Objective To explore the relationship between serum pregnancy-specific protein 1(PSG1),stress-induced protein 2(Sestrin 2),growth arrest-specific protein 6(Gas6)and uterine artery blood flow pa-rameters and fetal growth restriction(FGR)in patients with gestational hypertension(GH).Methods A to-tal of 485 GH patients admitted to Handan Maternal and Child Health Hospital from January 2020 to October 2023 were selected as the research objects and divided into the occurrence group(81 cases)and the non-occur-rence group according to whether FGR occurred.The correlations between serum PSG1,Sestrin 2,Gas6 and uterine artery blood flow parameters[pulse index(PI),resistance index(RI),ratio of peak systolic velocity to end diastolic velocity(S/D)]was analysed,as well as the related influencing factors of FGR in GH patients.In addition,a Nomogram model based on the influencing factors was constructed to analyze the predictive value.Results The serum PSG1 level in occurrence group was significantly lower than that in non-occurrence group,and the serum Sestrin 2,Gas6 levels and PI,RI,S/D values were significantly higher than those in non-occurrence group(P＜0.05).Pearson correlation results showed that serum PSG1 was negatively correlated with the uterine artery blood flow parameters PI,RI,and S/D,and the levels of serum Sestrin 2 and Gas6 were positively correlated with the uterine artery blood flow parameters PI,RI,and S/D(P＜0.05).Gestational di-abetes mellitus,umbilical cord abnormalities,high Sestrin 2,high Gas6,high PI,high RI,and high S/D were independent risk factors for the occurrence of FGR in GH patients(P＜0.05),and increased PSG1 level was protective factor for the occurrence of FGR in GH patients(P＜0.05).Receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC)of the Nomogram prediction model con-structed based on the influencing factors for predicting the occurrence of FGR in GH patients was 0.982,and the sensitivity and specificity were 0.943 and 0.938,respectively.The internal verification of the Bootstrap method shows that the Bias-corrected prediction curve basically coincides with the Ideal line,and the consis-tency index(C-index)was 0.964,indicating that the model was relatively stable.The decision curve shows that the threshold probability of this model was 0.01-1.00 and the net return rate was above 0.Conclusion Ser-um PSG1,Sestrin 2 and Gas6 in GH patients are closely related to uterine artery blood flow parameters and FGR,and the three are the influencing factors for the occurrence of FGR in GH patients.The constructed No-mogram model has a good predictive efficacy for FGR.

Objective To investigate the impact of high-frequency repetitive transcranial magnetic stimula-tion(rTMS)combined with biofeedback-assisted dry swallowing training on treating dysphagia following a stroke.Methods A total of 152 patients with dysphagia after stroke,admitted to the hospital from January 2022 to January 2024,were randomly divided into four groups using a random number table,with 38 cases in each group.The biofeedback group received biofeedback-assisted dry swallowing training,the magnetic stimulation group received high-frequency rTMS on the unaffected side,the combined group received both biofeedback-assisted dry swallowing training and high-frequency rTMS on the unaffected side,and the placebo group received conventional swallowing training and sham rTMS.All interventions lasted for 4 weeks.Clinical efficacy was recorded,and pre-and post-treatment assessments of the upper esophageal sphincter(UES)opening time,opening degree,and pharyngeal contraction duration were performed using multifunctional esophageal manometry.Additionally,swallowing func-tion,nutritional status,neurological function,and quality of life were compared.Results The clinical efficacy of the combined group was higher than that of the biofeedback and magnetic stimulation groups.Post-treatment UES opening time,opening degree,and pharyngeal contraction duration were(205.33±29.01)ms,(1.14±0.34)cm,and(559.19±63.48)ms,respectively,which were significantly better than those in the other 3 groups(P<0.05).The swallowing function scores of the combined group were(6.04±0.83)and(20.03±3.26)points,and significant improvements were observed in swallowing function,nutritional status,neurological function,and quality of life(P<0.05).Conclusion High-frequency rTMS combined with biofeedback-based dry swallowing training signifi-cantly improves the efficacy in the treatment of dysphagia after stroke.

Objective:To compare the significantly differentially expressed proteins in peripheral blood mononuclear cells between patients with different types of depressive disorders and normal participants and explore objective biomarkers with diagnostic significance.Methods:From March to May 2024, peripheral blood samples were collected from bipolar depression (BP), simple depression (DEP), persistent depressive disorder (PDD), and normal participants (NP) at the outpatient department of the Mental Health Center of Ningxia Medical University General Hospital.

Objective:To evaluate the efficacy and safety of Luofuoshan-Baicao oil (LBO) and wind medicated oil for the treatment of Aedes albopictus bites. Methods:A paired self-controlled study was conducted. Thirty-six healthy volunteers were recruited from Guangdong Provincial Hospital of Traditional Chinese Medicine from February 2023 to March 2023. Each participant's forearms were subjected to Aedes albopictus bites, with 3 bites on each arm. For the first 18 participants, LBO was applied to the left arm, and wind medicated oil to the right arm; for the latter 18 participants, wind medicated oil was applied to the left arm, and LBO to the right arm. The observation period was 24 hours. Within the first 3 hours after the mosquito bites, the topical agents were applied once every other hour for a total of 3 sessions, with an applicator centered on the bite site at a dose of approximately 50 μl, covering a skin area of about 2 cm in diameter; after 3 hours, participants applied the topical agents themselves until symptoms subsided or the 24-hour observation period ended. All subjects were followed up at the occurrence of skin lesions after mosquito bites, 0 to 3 hours after the first treatment, as well as 24 hours after the first treatment. During the follow-up, the effects of both topical agents on pruritus, erythema, papules, or wheals were evaluated, differences in treatment frequency were analyzed, and treatment-related adverse events were recorded. The time to disappearance of pruritus after treatment was statistically analyzed using Kaplan-Meier survival analysis, and intergroup differences were analyzed using the log-rank (Mantel-Cox) test. Two independent samples t-test was used for comparisons of other measurement data, and Pearson's chi-square test or Fisher's exact test was used for comparisons of count data between groups. Results:Within 3 hours after the first treatment, the time to initial disappearance of pruritus was significantly shorter in the LBO group (20.71 ± 1.92 min) than in the wind medicated oil group (28.30 ± 2.20 min, P < 0.05). The cumulative pruritus rate (the proportion of participants with pruritus among all participants) over time showed an overall stable fluctuation, and the cumulative pruritus rates at all observation points were significantly lower in the LBO group than in the wind medicated oil group ( P<0.05). After 3 hours of treatment, the mean values of changes in erythema diameters were 25.83 mm in the LBO group and 26.24 mm in the wind medicated oil group, while the mean values of changes in papule or wheal diameters were 8.25 mm in the LBO group and 9.18 mm in the wind medicated oil group; within 24 hours after the first treatment, the average time to disappearance of papules or wheals was 71.85 minutes in the LBO group and 73.01 minutes in the wind medicated oil group, while the average time to disappearance of erythema was 82.27 minutes in the LBO group and 84.86 minutes in the wind medicated oil group; there were no significant differences in the above observational indices between the two groups (all P > 0.05). The number of pruritus episodes within 24 hours of treatment was 56 in both the LBO group and wind medicated oil group, and the treatment frequency was 107 in both two groups; there were also no significant differences in the frequencies of pruritus episodes or treatment (both P > 0.05). No adverse events or reactions occurred during the trial. Conclusion:LBO was more effective than wind medicated oil in reducing the time to disappearance of pruritus after Aedes albopictus bites, with a high safety profile.

Neuronal injury in glaucoma persists despite effective intraocular pressure (IOP) control, necessitating neuroprotective strategies for retinal ganglion cells (RGCs). In this study, we investigated the neuroprotective role of the γ-hydroxybutyrate analog HOCPCA in a glaucoma model, focusing on its effects on CaMKII signaling, oxidative stress, and neuroinflammatory responses. Retinal tissue from high IOP animal models was analyzed via proteomics. In vitro mouse retinal explants were subjected to elevated pressure and oxidative stress, followed by HOCPCA treatment. HOCPCA significantly mitigated the RGC loss induced by oxidative stress and elevated pressure, preserving neuronal function. It restored CaMKIIα and β levels, preserving RGC integrity, while also modulating oxidative stress and neuroinflammatory responses. These findings suggest that HOCPCA, through its interaction with CaMKII, holds promise as a neuroprotective therapy for glaucoma.

Objective:To systematically synthesize the real experiences of women who have undergone emergency cesarean sections, providing evidence-based insights to inform the development of personalized care strategies.Methods:A comprehensive literature search was conducted across PubMed, Web of Science, Embase, CINAHL, Cochrane Library, PsycINFO, ProQuest, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc for qualitative and mixed-methods studies related to the psychological experiences of women who underwent emergency cesarean sections. The search covered all publications up to January 31, 2025. The methodological quality of included studies was appraised using the Joanna Briggs Institute Center for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. The results were integrated using an aggregative synthesis approach.Results:A total of 16 studies were included, from which 78 findings were extracted and grouped into nine new categories. These were further synthesized into three overarching themes: shift in birth plan and emergence of dynamic emotional responses; desire for diversified external support and encouragement; emotional investment and character growth.Conclusions:Women undergoing emergency cesarean sections commonly experience intense negative emotions. It is essential for healthcare providers and family members to pay close attention to the physical and psychological well-being of postpartum women, offer timely emotional support, and help them recover from psychological trauma, thereby promoting maternal mental and physical health.
