AIM:To investigate the prevalence of visual impairment and its correction status among junior high school students in Xi'an, so as to provide evidence for the development of targeted myopia prevention and control strategies.METHODS: A stratified cluster sampling design was adopted. From March to May 2025, students in grades 7-9 were recruited from three schools in Xi'an, Shaanxi Province, China: Dongfang Middle School, the Middle School Attached to Xi'an University of Technology, and the Xingqing Campus of the High School Affiliated to Xi'an Jiaotong University. In total, 3 974 students were invited, including 1 726 in grade 7, 1 206 in grade 8, and 1 042 in grade 9. The visual acuity was measured monocularly using a 5 m standard logarithmic visual acuity chart, with the fellow eye occluded; the line corresponding to the smallest optotype that could be correctly identified was recorded as the visual acuity value. Non-cycloplegic autorefraction was performed with a desktop autorefractor to obtain spherical equivalent(SE)values for refractive error screening.RESULTS: This study initially included 3 974 students, of whom 32 did not participate in the vision test, resulting in 3 942 students being included in the final analysis. Among them, 3 067(77.80%)were identified with poor vision. The prevalence of myopia was 81.47%(1 746)in males and 87.55%(1 575)in females(P<0.01). A stratified analysis by grade showed myopia rates of 81.72%(1 386)in junior grade one, 84.47%(1 017)in junior grade two, and 88.10%(918)in junior grade three, demonstrating a significant upward trend with increasing grade level(χ2=19.8484, P<0.01). Among the 3 321 myopic students, 2 287 adopted corrective measures. The rates of full correction, under-correction, and non-correction among all myopic students were 48.15%(1 599), 20.71%(688), and 31.14%(1 034), respectively. The rate of non-correction was significantly higher in male students than in females(32.70% vs 29.40%, χ2=4.2222, P<0.05).CONCLUSION: The findings indicate a high prevalence of visual impairment among junior high school students in Xi'an, coupled with suboptimal spectacle-wearing and full-correction rates. There is an urgent need for collaborative efforts across society, schools, and families to implement effective interventions to slow the onset and progression of myopia in this population.

Objective To explore the feasibility and safety of robotic-assisted laparoscopic Boari flap reconstruction for middle and distal ureteral stricture.Methods A retrospective study was made on 22 cases of middle and distal ureteral stricture between February 2019 and September 2022 in our department.The patients underwent DaVinci robotic-assisted laparoscopic middle and distal ureterectomy.Then flap of bladder was released and excised to perform Boari flap reconstruction for recuperating ureteral patency.Results The length of ureteral stricture ranged 7-10 cm(mean,9.3 cm).The operation time was 110-190 min(mean,132 min)and the intraoperative blood loss was50-150 ml(mean,87 ml).All the 22 cases were followed up for 12-44 months(mean,28 months).None of patients suffered from postoperative surgical side ureteral obstruction or vesicoureteral reflux.Conclusion Robotic-assisted laparoscopic Boari flap reconstruction for middle and distal ureteral stricture is safe and feasible,having definite therapeutic efficacy.

Objective To compare the efficacy and safety of defocus incorporated soft contact lenses(DISC)and orthokeratology(Ortho-K)for myopia control in children aged 8～15 years,and to further investigate the influence of dif-ferent baseline age and spherical equivalent(SE)on the treatment effect.Methods A retrospective cohort study was conducted,involving 197 myopic children(197 eyes)aged 8～15 years who were fitted with contact lenses at the Depart-ment of Ophthalmology,Xi'an People's Hospital(Xi'an Fourth Hospital)from May to September 2023.They were divid-ed into the DISC group(97 cases)and the Ortho-K group(100 cases).After 12 months of continuous follow-up,the chan-ges in axial length(AL)at 3,6,and 12 months after lens wear were compared between the two groups.Subgroup analysis was then performed:participants were divided into a younger subgroup(8～10 years)and an older subgroup(11～15 years)based on pre-wear age,and into a low myopia subgroup(-1.00～-3.00 D)and a moderate myopia subgroup(-3.25～-6.00 D)based on pre-wear SE.The AL changes at 3,6,and 12 months after wearing DISC or Ortho-K were com-pared between groups within these subgroups.Meanwhile,the incidence of conjunctivitis,incidence of corneal staining,corneal endothelial cell density,and corneal thickness were compared between the two groups at 12 months after lens wear.Results Inter-group comparisons showed:The change in AL in the DISC group at 3 months after lens wear was significantly lower than that in the Ortho-K group,and the difference was statistically significant(P＜0.05);at 6 and 12 months after lens wear,the differences in AL change between the two groups were not statistically significant(both P＞0.05).Subgroup analysis by age and SE showed:In the younger subgroup and the low myopia subgroup,the AL change in the DISC group at 3 months after lens wear was significantly lower than that in the Ortho-K group,and the differences were statistically significant(both P＜0.05),but these differences disappeared at 6 and 12 months after lens wear(all P＞0.05);in the older subgroup and the moderate myopia subgroup,the differences in AL change between the two groups at 3,6,and 12 months after lens wear were not statistically significant(all P＞0.05).At 12 months after lens wear,there were no statistically significant differences in the incidence of conjunctivitis,incidence of corneal staining,corneal endothe-lial cell density,or corneal thickness between the DISC and Ortho-K groups(all P＞0.05).Conclusion DISC demon-strates superior myopia control efficacy in the short term(3 months)for younger children and those with low myopia,but its medium-term(6 months)and long-term(12 months)efficacy converges with that of Ortho-K.Furthermore,the long-term safety of DISC is not significantly different from that of Ortho-K.

OX40 is a costimulatory receptor that is expressed primarily on activated CD4⁺, CD8⁺, and regulatory T cells. The ligation of OX40 to its sole ligand OX40L potentiates T cell expansion, differentiation, and activation and also promotes dendritic cells to mature to enhance their cytokine production. Therefore, the use of agonistic anti-OX40 antibodies for cancer immunotherapy has gained great interest. However, most of the agonistic anti-OX40 antibodies in the clinic are OX40L-competitive and show limited efficacy. Here, we discovered that BGB-A445, a non-ligand-competitive agonistic anti-OX40 antibody currently under clinical investigation, induced optimal T cell activation without impairing dendritic cell function. In addition, BGB-A445 dose-dependently and significantly depleted regulatory T cells in vitro and in vivo via antibody-dependent cellular cytotoxicity. In the MC38 syngeneic model established in humanized OX40 knock-in mice, BGB-A445 demonstrated robust and dose-dependent antitumor efficacy, whereas the ligand-competitive anti-OX40 antibody showed antitumor efficacy characterized by a hook effect. Furthermore, BGB-A445 demonstrated a strong combination antitumor effect with an anti-PD-1 antibody. Taken together, our findings show that BGB-A445, which does not block OX40-OX40L interaction in contrast to clinical-stage anti-OX40 antibodies, shows superior immune-stimulating effects and antitumor efficacy and thus warrants further clinical investigation.

ObjectiveTo analyze the occurrence of suspected adverse events following immunization （AEFI） after changing the priority vaccination sites of the adsorbed acellular diphtherior-pertussis-tetanus vaccine （hereinafter referred to as DPT vaccine）， so as to provide scientific basis for mass vaccination. MethodsMonitoring data of AEFI for the DPT vaccine in Wujiang District from September 2020 to August 2022 were collected from China's disease prevention and control information system， and the vaccination information of DPT vaccine in all children's vaccination clinics in Wujiang District during the same period was selected. The incidence of AEFI for the DPT vaccine was analyzed and compared. ResultsThe reported incidence of AEFI was significantly lower in the buttocks than that in other sites （P<0.05）. The reported incidence of AEFI was significantly higher in booster immunization than that in basic immunization （P<0.05）. After inoculation at different sites， the main clinical symptoms of AEFI were local redness and swelling. There were significant differences in the incidence of local redness and swelling， local induration， pruritus and other symptoms （lethargy， abnormal crying， etc.） （P<0.05）. There were significant differences in the severity of local redness and swelling in different sites （P<0.05）. The degree of redness and swelling in the anterolateral thigh was lower than that in other sites （P<0.05）. The local strong reaction of swelling （>5.0 cm） in the deltoid muscle of the upper arm was significantly higher than that in the buttocks （P<0.05）. ConclusionThe DPT vaccine is safe in different parts of the body and is worth popularizing.

Objective:To analyze the effect of the implementation of diagnosis-intervention packet (DIP) on the doctors′ diagnosis and treatment behavior of chronic diseases, so as to provide reference for further improving medical insurance payment related policies.Methods:The first page information of chronic disease patients admitted to hospitals with diabetes, hypertension and coronary atherosclerotic heart disease as the main conditions in 103 hospitals at all levels and township health centers in a city from 2016 to 2020 was collected, and the patients were divided into non-DIP group and DIP group according to the implementation time of DIP. After 1∶1 propensity score matching to balance the general conditions of the 2 groups, the diagnosis and treatment behaviors were analyzed from two dimensions: diagnostic behavior and treatment behavior. The grade A rate of medical record writing, admission and discharge diagnosis coincidence rate, and the average length of stay were used to evaluate the diagnostic behavior; the proportion of drugs and the degree of change in the cost structure were used as the evaluation indicators of treatment behavior.Results:After matching, 41 050 patients were included in both the non-DIP group and the DIP group.From the perspective of diagnostic behavior, the grade A rate of medical record writing in the non-DIP group and the DIP group was 99.40% and 99.83%, the coincidence rate of admission and discharge diagnosis was 58.42% and 61.79%, the average hospital stay was 8.03 days and 7.04 days respectively, and the difference between the groups was significant ( P<0.05). From the view of treatment behavior, the proportion of drugs decreased from 33.00% in the non-DIP group to 27.59% in the DIP group, with a significant difference ( P<0.05); the drug cost represented by Western medicine changed negatively, while the diagnostic cost showed a positive change. Conclusions:DIP has played a certain role in regulating doctors′ diagnosis and treatment behavior for chronic diseases. Among them, doctors have significantly improved their diagnostic behavior for chronic diseases, and the proportion of drugs in treatment behavior has been well controlled.

Objective:To investigate the effects of repetitive transcranial magnetic stimulation combined with paroxetine hydrochloride on executive function in depressed adolescents with non-suicidal self-injury.Methods:The clinical data of 120 depressed adolescents with depressive disorders who were admitted to The Second Hospital of Jinhua from August 2021 to July 2022 were retrospectively analyzed. They were randomly assigned to undergo treatment either with paroxetine hydrochloride (control group, n = 60) or repetitive transcranial magnetic stimulation combined with paroxetine hydrochloride (observation group, n = 60). All patients were treated for 2 months. Hamilton Depression Rating Scale-24 (HAMD-24) score, Non-suicidal Self-injury Behavior and Function Scale for Adolescents (ANSSIQ) score, executive function, brain-derived neurotrophic factor, 5-hydroxytryptamine, and clinical efficacy were determined in each group. Results:After treatment, the Hamilton Depression Rating Scale-24 score in the observation group was significantly lower than that in the control group [(15.85 ± 1.08) points) vs. (18.72±1.21) points, t = 13.71, P < 0.001). After treatment, the number of self-injury attacks, number of self-injury impulsions, and the intensity of self-injury thought within 2 weeks in the observation group were significantly lower than those in the control group ( t = 3.42, 3.03, 1.92, all P < 0.05). The scores of the Trail Making Test, Stroop Word test, Stroop Color test, and Stroop Color-Word Interference Test were significantly higher in the observation group than those in the control group ( t = 2.66, 3.33, 3.97, 4.64, all P < 0.01). Brain-derived neurotrophic factor and 5-hydroxytryptamine levels in the observation group were (11.45 ± 1.79) μg/L and (136.68 ± 11.90) μg/L, respectively, which were significantly higher than (9.06±2.21) μg/L and (124.82 ± 10.34) μg/L in the control group ( t = 6.51, 5.83, both P < 0.001). The total response rate in the observation group was significantly higher than that in the control group (91.7% vs. 78.3%, Z = 2.73, P = 0.006). Conclusion:Repetitive transcranial magnetic stimulation combined with paroxetine hydrochloride is highly effective on depressive disorders in adolescents with non-suicidal self-injury. The combined therapy can reduce symptoms, improve executive function and cognitive function, and optimize serological indicators, and thereby deserves the clinical promotion.
