AIM: To evaluate the postoperative clinical efficacy of non-diffractive extended depth of focus intraocular lens(EDOF IOL)in patients with highly myopic cataract(HMC).METHODS:A retrospective analysis was conducted on the clinical data of patients diagnosed with HMC at the hospital from January 2022 to December 2024. Patients were divided into an observation group [undergoing femtosecond laser-assisted cataract surgery(FLACS)combined with non-diffractive EDOF IOL implantation] and a control group(undergoing FLACS combined with aspheric monofocal IOL implantation)according to the type of implanted IOL. Postoperative visual acuity(LogMAR), visual quality, and patient satisfaction were compared between the two groups.RESULTS: A total of 33 patients(47 eyes)were finally included in this study, including 10 patients(17 eyes)in the observation group and 23 patients(30 eyes)in the control group. The observation group had a median age of 59.0(52.8, 63.8)y, with 8 males(13 eyes)and 2 females(4 eyes). The control group had a median age of 56.0(53.5, 60.0)y, with 13 males(17 eyes)and 10 females(13 eyes). At 3 mo postoperatively, the best-corrected distance visual acuity(BCDVA)was 0.10(0.08, 0.12)in the observation group and 0.20(0.10, 0.40)in the control group(P=0.586). However, the best-corrected intermediate visual acuity(BCIVA)[0.10(0.10, 0.10)vs 0.50(0.40, 0.90), P=0.032] and best-corrected near visual acuity(BCNVA)[0.20(0.18, 0.20)vs 0.60(0.45, 1.45), P=0.044] in the observation group were significantly better than those in the control group. The defocus curve showed that the uncorrected visual acuity(UCVA)in the observation group was relatively stable within the range of -2.00 to +1.00 D, which was superior to that in the control group. Postoperative questionnaires showed that the spectacle independence rate(76%)and overall satisfaction(88%)in the observation group were significantly higher than those in the control group(10% and 60%, respectively).CONCLUSION: Non-diffractive EDOF IOL significantly improves intermediate and near visual acuity, reduces spectacle dependence, and maintains distance visual acuity by extending the depth of focus, providing better postoperative visual quality and life satisfaction for HMC patients.

Objective: To analyze the association between drinking behaviors and anxiety symptoms, with the mediating role of insomnia symptoms among college freshmen, so as to provide a reference basis for reducing the occurrence of anxiety symptoms in college freshmen. Methods: From October to December 2021, 31 856 freshmen were selected by the purposive sampling method in 22 colleges across 11 provinces (Fujian, Jiangsu, Guangdong, Henan, Anhui, Hubei, Shanxi, Jiangxi, Shaanxi, Yunnan, Chongqing) in China. The Semi quantitative Food Frequency Questionnaire was used to investigate college freshmen drinking behaviors. The Depression Anxiety Stress Scale 21 and the Insomnia Severity Index were used to assess anxiety symptoms and insomnia symptoms in college freshmen. The generalized linear model was employed to analyze the association between drinking behaviors and anxiety symptoms in college freshmen, and the structural equation modeling was used to assess the mediating effect of insomnia symptoms on the association. Results: The detection rate of anxiety symptoms among college freshmen was 28.2%, the detection rates of the mild, moderate, severe and extremely severe were 6.6%, 15.9%, 3.2% and 2.6%, respectively. While 23.6% of college freshmen reported drinking in the past month, the rates were 39.8% among boys and 15.9% among girls. After adjusting for demographic variables (ethnicity, education, major, etc.) and confounding variables (self evaluation of learning burden, number of close friends, screen time, etc.), the results of generalized linear model analysis showed that beer consumption was associated with anxiety symptoms in college freshmen( β =0.09, 95% CI =0.04-0.14), girls( β =0.14, 95% CI =0.07-0.21) and those aged 19-20 years ( β =0.12, 95% CI =0.05-0.19)(all P <0.05). Red wine consumption was associated with anxiety symptoms in male students ( β =0.13, 95% CI =0.02-0.24, P <0.05). Alcohol and beer consumption were associated with insomnia in college freshmen[ β (95% CI ) =0.22(0.08-0.36),0.31(0.23-0.39),both P <0.01]. Insomnia symptoms partially mediated the association between drinking behaviors and anxiety symptoms among college freshmen with a mediating effect value of 0.05, accounting for 50.49% of the total effect. Conclusions Insomnia symptoms partially mediates the association between drinking behaviors and anxiety symptoms in college freshmen. Measures should be taken to simultaneously intervene in the drinking behaviors and insomnia symptoms of college freshmen to prevent the occurrence of their anxiety symptoms.

Objective: To statistically analyze the association between blood donation intervals and the incidence of adverse reactions to blood donation based on blood donor data from Shenzhen. Methods: Basic data and records of adverse reactions to blood donation among voluntary whole blood donors in Shenzhen from January 2017 to June 2025 were extracted. A total of 795 404 whole blood donations were recorded, including 502 743 from males and 292 661 from females, with 1 088 and 751 cases of adverse reactions, respectively. Analyses were performed using R software, including restricted cubic spline (RCS), binary logistic regression, and generalized estimating equations (GEE) to evaluate the correlation between donation intervals and adverse reactions. Results: A total of 1 839 cases of adverse reactions were recorded, accounting for 0.23% of the total donations. Both binary logistic regression analysis and the generalized estimating equations (GEE) model showed that there was no significant difference in the incidence of adverse reactions between male and female donors with an interval of ≥6 months compared to those with an interval of ≥3 months but<6 months. Furthermore, using the 3-5 month interval group as the reference, the analysis indicated that the incidence of adverse reactions significantly increased in males with a 9-12 month interval, while no statistically significant differences were observed across any of the female subgroups. Conclusion: There was no significant correlation between adverse reactions to blood donation and the donation interval. Compared with a donation interval of ≥6 months, an interval of<6 months does not lead to an increase in the incidence of adverse reactions among male or female donors. The findings of this study may help enhance the willingness of blood donors to participate.

Objective: To statistically analyze the association between blood donor age and the incidence of adverse reactions based on whole blood donor data from Shenzhen. Methods: Data on basic characteristics and records of adverse donation reactions among voluntary whole blood donors in Shenzhen from January 2017 to June 2025 were extracted. A total of 795 404 whole blood donations were recorded, including 502 743 from males and 292 661 from females, with 1 088 and 751 cases of adverse reactions, respectively. Analyses were performed using R software, including restricted cubic spline (RCS) analysis, binary logistic regression, and generalized estimating equations (GEE) to evaluate the correlation between donor age and adverse reactions. Results: A total of 1 839 cases of adverse reactions were recorded, accounting for 0.23% of the total donations. Both binary logistic regression and GEE model revealed that, compared with the≤55 years age group, the incidence of adverse reactions was reduced in both male and female donors in the >55 years age group, with the difference being statistically significant in males. Using the <23 years age group as a reference, the incidence of adverse reactions significantly decreased in both male and female donors across the 23-30, 31-40, 41-50, and 51-60 age groups, with the differences being statistically significant. Conclusion: There is a negative correlation between the rate of adverse donation reactions and age, with the incidence of such reactions among whole blood donors over 55 years old being no higher than that among donors aged 55 years or younger. These findings carry positive significance for safeguarding the donation rights of older donors and meeting clinical blood demand.

Objective: To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents. Methods: A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models. Results: The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05). Conclusions Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

Objective: Some regions in China have lowered the minimum interval for whole blood donation to 3 months through local regulations: Hainan, effective from March 1, 2012, allows men to donate at intervals of≥3 months and women at intervals of≥4 months; Shenzhen, effective from November 1, 1995, allows whole blood donation at intervals of≥3 months. The aim of this study was to evaluate the impact of shortening the whole blood donation interval on blood donation adverse reactions and donation behavior, thereby providing scientific evidence for policy evaluation and revision of relevant regulations. Methods: This was a multicenter, retrospective cohort study based on blood donation registry data from Shenzhen and Hainan. Data were obtained from the blood information management systems of Hainan Province (1991-2025) and Shenzhen City (2018-2024). Eligible participants were donors aged 18-65 years who had donated whole blood at least twice and met health eligibility criteria. The exposure was defined as a shorter donation interval (whole-blood interval≥3 months and<6 months) and was treated as a time-varying variable. The primary outcome was blood donation adverse reactions. Negative binomial regression with person-years as an offset was used to estimate incidence rate ratios for adverse reactions. Marginal standardization was used to estimate the adjusted incidence rate difference, and donor-level bootstrap resampling was used to estimate the 95% confidence interval of the adjusted incidence rate difference. Non-inferiority was assessed by comparing the upper limit of the 95% confidence interval with the prespecified non-inferiority margin of Δ=0.00 070 per person-year. In addition, Andersen-Gill models were used to analyze adverse reaction-free probability for recurrent events. Secondary outcomes were donation behavior, including annual repeat donation rate, annual donation frequency, mean donation interval, and annual whole-blood donation volume. These were analyzed using logistic regression, negative binomial regression, and linear regression models, respectively, with adjustment for age, sex, region, and donation site. This study was approved by the Ethics Committee of the Institute of Blood Transfusion, Chinese Academy of Medical Sciences (Approval No.2025011) and registered in the Chinese Clinical Trial Registry (ChiCTR2500114968). Results: A total of 375 075 repeat whole-blood donors were included, contributing 1 292 748 whole-blood donations. Among them, 119 993 had ever donated at a shorter interval and 255 082 had never done so. Over 1 281 842 person-years of follow-up in the dynamic cohort, 2 100 blood donation adverse reactions were recorded. The incidence rates of adverse reactions were 1.76 and 1.58 per 1 000 person-years in the ever-short interval and never-short interval groups, respectively. After adjustment for age, sex, province, and donation site, the ever-short interval group had a slightly higher adverse reaction rate than the never-short interval group (IRR=1.28, 95%CI: 1.15-1.41, P<0.001). Marginal standardization showed that the adjusted incidence rates were 1.73 and 2.21 per 1 000 person-years in the never-short interval and ever-short interval groups, respectively. The adjusted incidence rate difference was 0.000 48 per person-year, with a bootstrap 95%CI of 0.000 26-0.000 69 per person-year; the upper limit of the 95%CI was below the prespecified non-inferiority margin. Andersen-Gill recurrent-event analysis showed that the ever-short interval group had a higher probability of remaining adverse reaction-free. Analysis of donation behavior showed that among donors followed for at least 365 days, the ever-short interval group had a higher annual repeat donation rate than the never-short interval group (74.2% vs 18.3%; adjusted OR=12.5, 95%CI: 12.3-12.7, P<0.001). They also had a higher annual whole-blood donation rate (adjusted RR=1.98, 95%CI: 1.97-1.98, P<0.001), a shorter mean whole-blood donation interval (β=-239 days, 95%CI: -242 to -237 days, P<0.001), and a higher annual whole-blood donation volume (adjusted RR=2.14, 95%CI: 2.13-2.15, P<0.001). Conclusion: Based on real-world data from repeat whole-blood donors in Shenzhen and Hainan, lowering the minimum whole blood donation interval to 3 months did not show an absolute increase in blood donation adverse reactions exceeding the prespecified margin within the scope of this outcome. Shorter whole-blood donation interval behavior was also associated with greater repeat-donation activity, higher annual donation frequency, and higher annual whole-blood donation volume. Given the observational nature of this study and the lack of long-term donor health indicators such as iron status and longitudinal hemoglobin changes, the long-term safety of setting the minimum whole blood donation interval at 3 months requires further evaluation.

Objective:To investigate the clinical features of adherent perirenal fat (APF) in patients undergoing laparoscopic adrenal surgery through peritoneal approach, and to analyze its predictors and risk factors, so as to provide reference for clinical diagnosis and treatment.Methods:A total of 86 patients who received transabdominal approach laparoscopic adrenal surgery in the Department of Urology, the Rizhao Hospital of Traditional Chinese Medicine and the First Department of Minimally invasive Urology of Shandong Provincial Hospital from February 2021 to February 2024 were retrospectively selected as the study objects. According to whether patients developed APF during the operation, they were divided into APF group (29 cases) and non-APF group (57 cases). The Mayo Adhesive Probability (MAP) score and preoperative perirenal fat CT density were compared between the two groups. Receiver operating characteristic (ROC) curve was used to analyze the value of each index in predicting the occurrence of APF. Univariate and multivariate logistic regression models were used to analyze the influencing factors of the occurrence of APF.Results:The MAP score, CT density of perirenal fat (renal vein level, adrenal tumor level, normal adrenal gland level) and CT density score of the APF group were higher than those of the non-APF group, with statistical significance (all P<0.05). Age, body mass index (BMI), perirenal fat thickness and the proportion of diabetes mellitus and hyperlipidemia in the APF group were significantly higher than those in the non-APF group, with statistical significance (all P<0.05). The area under ROC curve predicted by MAP score, CT density of perirenal fat (renal vein level, adrenal tumor level, normal adrenal level) and CT density score for APF in patients undergoing laparoscopic adrenal surgery were 0.921, 0.655, 0.628, 0.538, and 0.912, respectively. Logistic regression model results showed that high MAP score, high CT density score, old age, high BMI, large perirenal fat thickness, and complicated diabetes were independent risk factors for APF in patients undergoing peritoneal laparoscopic adrenal surgery (all P<0.05). Conclusions:In patients with adrenal tumor treated by peritoneal laparoscopic adrenal surgery, MAP score and CT perirenal fat density examination before operation are beneficial to predict whether APF will occur, which has certain guiding significance for the formulation of surgical plan.

OBJECTIVE: To analyze a Chinese pedigree affected with Non-syndromic autosomal recessive deafness type 12 (NFNB12), validate the function of candidate variants, and explore the underlying mechanisms. METHODS: A NFNB12 pedigree presented at Henan Provincial People's Hospital in February 2023 was selected as the study subject. Whole exome sequencing (WES) was carried out, and candidate variant was verified by Sanger sequencing of the pedigree members. Reverse transcription polymerase chain reaction (RT-PCR) was used to determine the level of mRNA transcription in the peripheral blood samples from the pedigree members, and protein expression was evaluated with Western blotting assay. This study was approved by Medical Ethics Committee of Henan Provincial People's Hospital (Ethics No.: 2019-134). RESULTS: WES analysis revealed that the proband has harbored homozygous c.6688delG (p.Ala2230Profs*4) variant of the CDH23 gene, for which both parents were identified as heterozygous carriers. RT-PCR analysis demonstrated the sole presence of the variant mRNA in the proband, and both the variant and wild-type mRNAs in both parents. Furthermore, Western blotting analysis indicated that the proband had exclusively expressed the truncated CDH23 protein, while both the normal and truncated forms of the protein were noted in her parents. CONCLUSION The c.6688delG (p.Ala2230Profs*4) variant of the CDH23 gene probably underlay the pathogenesis of NFNB12 in this pedigree. The loss of function of the CDH23 gene resulting from this variant is not related with nonsense-mediated mRNA decay, but rather production of a truncated protein. Above finding has not only enriched the mutational spectrum of the CDH23 gene and offered a method for investigating the function of its variants using peripheral blood samples, but also delineated the molecular basis for the loss of function, which has provided crucial evidence for genetic counseling and prenatal diagnosis for this family.
