Objective To develop and validate a"quick self-assessment questionnaire for cochlear implant out-come(QSACI)".Methods A research team,composed of audiologists,otolaryngologists,data analysis experts,and cochlear implant(CI)recipients,was formed to establish objectives,research subject criteria,and framework of the QSACI.An item pool was creaed through literature review and brainstorming.Question items were evaluated and screened,and the framework and answer options of the questionnaire were established.The comprehensibility,etc.,was analyzed and refined through pilot test,interviews,and expert consultation,leading to the development of the final version.A total of 39 post-lingually deafened adults with known stable outcomes completed the question-naire.The split-half and test-retest reliabilty of the questionnaire was analyzed,and the validity was quantitatively analyzed by comparing scores with the categories of auditory performance(CAP)scores.Results The initial item pool of the questionnaire had 18 items,and the final questionnaire consisted of 12 questions in four dimensions:com-munication status,audiological status,medical factors,and other factors.The average score of 39 recipients was 88.81±6.17 and CAP was 6.19±0.94.The questionnaire showed good reliability and validity,with a Cronbach's alpha coefficient of 0.71 and a test-retest reliability of 0.824(P＜0.05).The criterion-related validity,assessed by the correlation between the self-assessment questionnaire scores and CAP scores,showed a significant moderate pos-itive correlation(r=0.512,P＜0.05).The correlation coefficient between self-assessment and professional assess-ment was 0.720(P＜0.05),indicating a significant correlation.The area under the receiver operating characterstic(ROC)curve was 0.82(P＜0.05),the cutoff values corresponding to the maximal Youden index were 82.5 and 88.6,therefore score of 85 was taken as the median threshold score of judgement.Conclusion The QSACI reflects the post-imlplant outcomes,and it can serve as a tool for people with postlingually deafness and their families to un-derstand the eligbility of CI and the expected outcomes,helping to establish realistic expectations before CI surgery.

We collected the positive serum of Echinococcus granulosus infection in sheep,an inter-mediate host with strong immune response,and used healthy serum as negative control,purified the serum and target protein to capture and enrich the corresponding antigen by immunoprecipita-tion,and obtained target protein-antibody-target protein complex.Mass spectrometry strategies were combined to screen and identify specific antigens associated with Echinococcus granulosus,and the proteins with the highest peptide coverage were analyzed bioinformatically using online prediction software.The results showed that 133 Echinococcus granulosus related proteins were i-dentified by IP-MS.Among them,one protein with peptide coverage≥70％was actin Ⅱ,and three proteins with peptide coverage between 30％to 40％were Ton B box domain containing protein,NADH dehydrogenase(ubiquinone)1 α-subcomplex 2(NADH dehydrogenase[ubiquinone])and lactic dehydrogenase.There were six proteins with 20％to 30％peptide coverage,namely,spli-cing factor 3B subunit 5,tumor protein D52,expressed conserved protein,NADH dehydrogenase(ubiquinone)1 alpha subcomplex 7,inosine-5'-monophosphate dehydrogenase,and aldo keto re-ductase family 1 member B4.Bioinformatics analysis revealed that actin protein has no signal pep-tide,it is probably a non-secretory protein and is subcellularly localized to the cytoskeleton,six op-timal potential antigenic epitopes are present,and the secondary and tertiary structures are consist-ently dominated by α-helices and irregular convolutions.The results indicate that immunoprecipita-tion-mass spectrometry is a high-throughput,simple,rapid and effective method for screening and identifying fine-grained Echinococcus granulosus antigens,which can provide a basis for screening specific molecules for serodiagnostic markers in intermediate host sheep and for the development of novel diagnostic techniques for hydatid diseases.

Objective To explore relationship between glucose metabolism and neonatal weight in high-risk gestational diabetes melli-tus(GDM).Method A retrospective study was conducted on 779 pregnant women who underwent prenatal examinations at Tongzhou Maternity and Child Health Care Hospital in Beijing from March to June 2022.The data on pre-pregnancy weight,mid-and late-preg-nancy glycated albumin(GA)and glycated hemoglobin(HbA1c),pre-delivery weight,gestational weight gain,and neonatal birth weight were collected.A GDM risk assessment model was established using multivariate logistic regression to classify pregnant women into high-risk and low-risk groups for GDM,followed by separate management strategies.Regression discontinuity(RD)analysis was applied to evaluate the relationship between gestational glucose metabolism status and neonatal birth weight.Results Among the 779 pregnant women,the overall incidence of macrosomia was 7.32％.The high-risk GDM group exhibited significantly higher pre-pregnan-cy weight,late-pregnancy HbA1c,and GA levels compared to the low-risk group(all P＜0.001).Neonatal birth weight in the high-risk group was significantly higher than that in the low-risk group(P＜0.05),with a significantly increased macrosomia incidence(13.55％vs 5.77％,P＜0.05).RD analysis revealed a jump reduction of 199.59 g(P=0.029)in neonatal birth weight at the risk score thresh-old.Conclusion Lifestyle glucose metabolism management in high-risk GDM pregnant women may effectively reduce neonatal birth weight,mitigated the trend of excessive gestational weight gain,and improved late-pregnancy HbA1c and GA levels,providing evi-dence-based support for maternal and child health services.

This study aims to analyze the screening results and epidemiological characteristics of prostate cancer (PCa) among elderly males in the rural areas of Songjiang, Shanghai City, through the implementation of a preliminary prostate-specific antigen (PSA) screening based on a community-linkage model, and to explore an effective screening approach. A retrospective observational study design was employed to collect data from residents who underwent PSA screening at Songjiang Hospital affiliated to Shanghai Jiao Tong University School of Medicine, in collaboration with multiple community health service centers in Songjiang District, Shanghai City, between June 2022 and June 2024, through free clinics and annual health examinations. Prostate biopsy was recommended for individuals with total PSA (tPSA) levels >10 ng/ml and those with 4 ng/ml≤tPSA≤10 ng/ml and abnormal free-to-total PSA (f/tPSA) ratios. Clinical characteristics of detected PCa patients were analyzed. Follow-up was conducted through phone calls and home visits by family doctors, coupled with enhanced health education. The results indicated that a total of 17 198 residents participated in the screening, among which 2 234 (12.99%) had tPSA levels between 4 ng/ml and 10 ng/ml, and 257 (1.49%) had tPSA levels >10 ng/ml. Ultimately, 417 residents underwent prostate biopsy, with 171 being diagnosed with PCa, yielding a positive biopsy rate of 41.00% and a PCa detection rate of 0.99%. The predominant pathological subtype among PCa patients was adenocarcinoma (168 cases, 98.24%). Of the 146 PCa patients who received treatment, the majority were classified as intermediate or high-risk (124 cases, 84.93%). Furthermore, with the optimization of the screening model, there was a significant increase in the proportion of subsequent outpatient visits. In conclusion, the community-linkage-based PSA screening model demonstrated high effectiveness in screening for PCa among elderly males in the rural areas of Songjiang, Shanghai City. Epidemiological findings revealed that PCa patients in this region are primarily composed of intermediate and high-risk groups, highlighting the need for intensified early screening and health education.

Objective To study the correlation between expression levels of serum Spexin and Pannexin 1 protein,glucose and lipid metabolism and insulin resistance in elderly patients with diabetic cataract.Methods A total of 118 elderly diabetic cataract patients were selected as the case group,and 103 elderly diabetic non-cataract patients were selected as the control group who were treated in the same hospital during the same period.Serum levels of Spexin and Pannexin1 were detected by enzyme-linked immunosorbent assay(ELISA).Fasting blood glucose(FPG)and glycosylated hemoglobin(HbA1c)were measured.Lipid metabolism related indicators including triacylglycerol(TG),high density lipoprotein cholesterol(HDL-C),total cholesterol(TC)and low density lipoprotein cholesterol(LDL-C)were detected in two groups of patients.Insulin resistance related indexes:fasting insulin(FINS),insulin sensitivity index(ISI),insulin resistance index(HOMA-IR)and islet beta cell function index(HOMA-β)were also detected.The correlation between serum Spexin and Pannexin1 levels,glucolipid metabolism and ISI was detected by Pearson method.Receiver operating characteristic(ROC)curves were used to assess the predictive value of serum Spexin and Pannexin1 levels and their combination in the development of cataract in elderly diabetic patients.Results The level of Spexin was lower in the observation group than that in the control group,and the level of Pannexin1 was higher than that in the control group(P＜0.01).Levels of TG,TC,LDL-C,FPG,HbA1c,FINS and HOMA-IR of the observation group increased compared with the control group,while HDL-C,ISI and HOMA-β levels decreased compared with the control group(P＜0.01).Pearson correlation analysis showed that serum Spexin level was positively correlated with ISI and HOMA-β,and negatively correlated with TG,TC,LDL-C,FPG,HbA1c,FINS and HOMA-IR in elderly patients with diabetic cataract(P＜0.05).Serum Pannexin1 was negatively correlated with ISI and HOMA-β,and positively correlated with TG,TC,LDL-C,FPG,HbA1c,FINS and HOMA-IR(P＜0.05).There was no correlation between the above indexes and HDL-C(P＞0.05).The combination of both serum Spexin and Pannexin1 predicted the development of cataracts in elderly diabetic patients was better than serum Spexin and Pannexin1 assessed individually(Z both combination-Spexin=3.220,P=0.001,Z both combination-Pannexin1=4.838,P＜0.001).Conclusion In elderly patients with diabetic cataract,the expression of serum Spexin decreases and the expression of Pannexin1 increases,and they have a certain correlation with glucose and lipid metabolism and insulin resistance

Objective:To compare the clinical effect of femoral neck system (FNS) and cannulated compression screw internal fixation in the treatment of femoral neck fractures in young and middle-aged patients.Methods:The databases of CNKI, Wanfang Data Knowledge Service Platform, VIP, Chinese Medical Journal Full-text Database, PubMed, Embase, Web of Science and Cochrane Library were searched. The intraoperative blood loss, intraoperative fluoroscopy times, hospital stay, fracture healing time, Harris hip function score, partial weight-bearing time and complication rate were extracted to compare the clinical efficacy of the two surgical methods. Stata18.0 statistical software was used for meta-analysis.Results:A total of 699 patients from 11 studies were included in this study. Compared with cannulated compression screw internal fixation, the FNS had a shorter operation time [ WMD= -8.54, 95% CI(-14.87, -2.21), P=0.008], fewer intraoperative fluoroscopy times[ WMD= -8.29, 95% CI(-11.45, -5.12), P< 0.001], a shorter fracture healing time [ WMD=-1.59, 95% CI(-2.49, -0.68), P=0.001], a shorter partial weight-bearing time[ WMD=-3.45, 95% CI(-4.43, -2.46), P<0.001], a lower incidence of postoperative complications [ RR=0.41, 95% CI(0.22, 0.76), P= 0.004], and a lower incidence of postoperative nonunion [ RR=0.40, 95% CI(0.18, 0.88), P=0.022]. Meanwhile, the FNS group had more intraoperative blood loss [ WMD=9.53, 95% CI(2.70, 16.35), P=0.006] and a higher Harris hip function score at the last follow-up [ WMD=3.50, 95% CI(2.11, 4.89), P<0.001] than the cannulated compression screw internal fixation group. There were no statistically significant differences in the length of hospital stay [ WMD=-0.48, 95% CI(-0.82, -0.13), P=0.092] or the incidence of femoral head necrosis [ RR=0.57, 95% CI(0.26, 1.24), P=0.159] between the two groups. Conclusion:Compared with cannulated compression screw internal fixation in the treatment of femoral neck fracture in young and middle-aged patients, FNS has more intraoperative blood loss, but it has more advantages in operation time, intraoperative blood loss, intraoperative fluoroscopy times, postoperative fracture healing time, Harris hip function score, partial weight-bearing time, postoperative nonunion rate and postoperative complications rate.

This paper interprets the disease name related to bi （痹） disease in traditional Chinese medicine （TCM） from the perspective of micropathological phenotypes in knee osteoarthritis （KOA）. By systematically reviewing classical TCM literature on the pathogenesis and clinical features of different subtypes such as damp-retention bi， bone bi， and tendon bi， and integrating these with current research on pathological subtypes of KOA including the synovitis type， cartilage-meniscus type， and subchondral bone type， the study explores the correlation between traditional disease terms and modern micropathological phenotypes. The author proposes subtype classifications of damp-retention bi corresponding to synovial inflammation， bone bi related to abnormal subchondral bone remodeling， and tendon bi representing cartilage and meniscus degeneration. This approach provides a microscopic biological explanation for TCM syndrome differentiation and offers new perspectives for advancing integrative diagnostic and therapeutic strategies in both Chinese and western medicine.

In recent years， hyperuricemia （HUA） has shown a rapidly increasing incidence and tends to occur in increasingly young people， with a wide range of cardiac， renal， joint， and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage， medication restriction， and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid （UA）， and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology， which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine （TCM） can treat HUA via multiple targets and multiple pathways from a holistic view， with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However， its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA， this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora， intestinal metabolites， intestinal UA transporters， and intestinal barriers. Furthermore， we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology， with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.
