AIM:To investigate the current status and influencing factors of knowledge-attitude-practice in myopia prevention and control among children and adolescents in Ningbo City, thereby providing a scientific basis for formulating targeted prevention strategies.METHODS: Children and adolescents aged 6-12 years old were selected from the medical-school collaborative myopia prevention network in Ningbo City between August 2024 and May 2025 using stratified cluster sampling. Information on myopia prevention knowledge(15 items)and practice(9 items)was collected through questionnaire surveys. Logistic regression models were used to analyze factors influencing myopia occurrence in children and adolescents.RESULTS: A total of 664 children and adolescents aged 6-12 years were enrolled in this study. Participants were divided by age into three groups: 6-7 years old(n=221), 8-9 years old(n=221), and 10-12 years old(n=222). Of the 664 questionnaires distributed, 637 valid questionnaires were returned(201 from the 6-7 age group, 235 from the 8-9 age group, and 201 from the 10-12 age group), yielding an effective response rate of 95.9%. Based on myopia screening results, the non-myopic group comprised 203 participants(31.9%), including 100 males and 103 females, with a mean age of 8.82±1.98 years old. The myopic group comprised 434 participants(68.1%), including 213 males and 221 females, with a mean age of 9.10±1.95 years old. The myopia prevalence rates in the 6-7, 8-9, and 10-12 age groups were 37.8%(76/201), 71.9%(169/235), and 94.0%(189/201), respectively(P<0.001). Regarding the knowledge and practice of myopia prevention, the overall awareness rate in the non-myopic group(59.7%±9.7%)was significantly higher than that in the myopic group(48.7%±8.5%; P<0.001). Additionally, the non-myopic group scored higher on the key practice of “regular eye examinations”(4.27±0.96)compared to the myopic group(4.10±1.05; P<0.05). Logistic regression analysis indicated that age was the primary risk factor for myopia occurrence.CONCLUSION: Age is the dominant factor in the onset of myopia, and there is a phenomenon of “knowledge-practice gap”; the traditional health education model has limitations, and a precise prevention and control system based on developmental patterns should be established.

AIM: To characterize the current status, research hotspots, and evolutionary differences in clinical studies on amblyopia published in Chinese and English from 2015 to 2025, and to provide a reference for the clinical diagnosis and treatment as well as relevant research of amblyopia.METHODS: Clinical studies on amblyopia in both Chinese and English were retrieved from the CNKI, VIP, Wanfang and Web of Science(WoS)databases. Bibliometric and visualization analyses of publication output, institutions, authors, and keywords were conducted using Cite Space 6.4.R1 and VOS viewer 1.6.19.RESULTS: Totally 1 302 publications were included, comprising 920 Chinese and 382 English publications. The publications of Chinese literature declined after 2019, while that of English literature showed an upward trend. Relevant studies involved 18 countries, and the institutional cooperation connections of English literature were relatively closer. The core author cooperation networks of both Chinese and English literature presented multi-cluster distribution. A total of 360 and 283 keyword nodes were obtained from Chinese and English literature, respectively. The high-frequency keywords of both literatures covered four aspects, including amblyopia types, research populations, evaluation indicators, and treatment methods. Both Chinese and English studies focus on anisometropic and strabismic amblyopia. Chinese studies predominantly investigated children of different age groups, whereas adult amblyopia received earlier attention in the English literature. Visual acuity, contrast sensitivity, and stereopsis were the major outcome measures of common interest, while optical correction and occlusion therapy remained the mainstay treatments. Totally 19 and 13 keyword clusters were identified in the Chinese and English literatures, respectively. Burst analysis indicated that digital treatment such as binocular dichoptic training appeared relatively early in English literature. In recent years, quality of life and risk factor screening for amblyopia received increasing attention. In Chinese literature, growing focus was placed on digital visual training and traditional Chinese medicine intervention. In addition, neuroimaging evaluation based on resting-state functional magnetic resonance imaging was conducted much earlier in English studies.CONCLUSION:From 2015 to 2025, Chinese and English clinical research on amblyopia has shown diversified development, with substantial similarities in the major types of amblyopia investigated, visual function assessment, and basic treatment modalities, but differences in the timing and emphasis of some research hotspots. Clinical research on amblyopia is gradually expanding from improvement in visual acuity toward restoration of binocular visual function, multidimensional outcome assessment, and investigation of visual neural mechanisms, while treatment strategies are becoming increasingly digitalized and individualized. Future research should further optimize standardized treatment, strengthen investigations into adult amblyopia, binocular digital vision training, visual neural mechanisms, and multidimensional outcome assessment, and evaluate the clinical value of integrated traditional Chinese and Western medicine interventions through high-quality clinical studies.

OBJECTIVE To investigate the use of common disposable and reusable supplies for prevention and con-trol of infections in Shanghai.METHODS A survey was conducted for the use and reuse of disposable high-value consumables,disposable bronchoscopes and environmental cleaning and disinfection tools in Shanghai by using structured questionnaire.RESULTS Totally 81 medical institutions were involved in the survey,44(54.32％)of which were tertiary hospitals,and the median number of beds was 500.The orthopedic implants(70.37％),ul-trasound knife(69.14％)and endoscopic puncture instrument(66.67％)were the high-value consumables rank-ing the top 3 utilization rates.There was reuse of 18 types of high-value consumables in total among the 12 medi-cal institutions.The major causes of reuse of high-value consumables included fee less tan cost of consumables(58.33％)or being unable to included in charge items(33.33％).27.78％of the recycle high-value consumables were not treated with a dedicated disinfection and sterilization system and procedures for the disposable high-value consumables,and 33.33％did not have the report systems for related adverse reactions.49.09％of the medi-cal institutions reported to use the disposable bronchoscopes,4 of which reused them.The majority of the medi-cal institutions could carry out centralized cleaning and disinfection for the recycled floor cloths(60.81％)and cloth towels(56.76％),and 32.43％of the medical institutions reused the cloth towels by manual cleaning.The utilization rate of antiseptic wipes was 75.41％in adult intensive care unit,62.50％in neonatal intensive care unit.CONCLUSION The study reveals that there are some problems in the use of disposal and reusable supplies for prevention and control of infections,which may provide baseline data for management of the related supplies and the surveillance of disinfection of the recycled supplies so as to enhance the quality of management of hospital-asso-ciated infections.

Objective:To observe the clinical efficacy of gentle moxibustion at different temperatures in treating people with diarrhea-predominant bowel syndrome(IBS-D)due to spleen deficiency.Methods:A total of 108 IBS-D patients were divided into two groups using the random number table method,with 54 participants in each group.Moxibustion group 1 received gentle moxibustion at(43±1)℃at bilateral Tianshu(ST25)and Zusanli(ST36),lasting 30 min each session;moxibustion group 2 received gentle moxibustion at(37±1)℃at the same points.Both groups received the intervention 3 times weekly for a total of 18 sessions.Abdominal pain intensity,stool form,pattern-based efficacy,quality of life,and mental health assessments were performed at weeks 0,3,6,and 8.Results:The total effective rate for abdominal pain intensity was 87.8%in moxibustion group 1 versus 51.1%in moxibustion group 2,and the difference was statistically significant(P<0.05).When the treatment finished,abdominal pain intensity,the Bristol score,IBS-symptom severity scale(IBS-SSS)score,self-rating anxiety scale(SAS)score,and self-rating depression scale(SDS)score dropped significantly in both groups(P<0.05),and the IBS-quality of life(IBS-QOL)score increased markedly(P<0.05).Between-group comparisons demonstrated that abdominal pain intensity,the Bristol general score,IBS-SSS score,traditional Chinese medicine(TCM)pattern score,and SDS score were significantly lower in moxibustion group 1 than in moxibustion group 2 at treatment week 6(P<0.05),and the IBS-QOL score was notably higher in moxibustion group 1(P<0.05).Conclusion:Whether at 43℃or 37℃,gentle moxibustion at Tianshu(ST25)and Zusanli(ST36)can improve abdominal pain,stool form,and quality of life,reduce disease severity,and mitigate TCM pattern in IBS-D patients;43℃gentle moxibustion performs better than 37℃gentle moxibustion in improving abdominal pain,stool form,disease severity,TCM pattern,quality of life,anxiety,and depression in IBS-D.

The theory of"eyes as the convergence of various meridians"recorded in the Ling Shu Kouwen chapter is the theoretical basis for acupuncture treatment of eye diseases.This article explained the theoretical connotation of"eyes as the convergence of various meridians"from this perspective:eyes rely on the circulation of the twelve meridians and the nourishment of qi and blood to maintain the divine radiance;the penetrating operation of the twelve meridians enhances the close connection between the eyes,the brain,and various related organs.Based on the above theoretical basis,the basic pathogenesis of amblyopia patients with"lack of dependence on qi and unclear visual perception"was summarized.The treatment principle is"regulating qi and meridians,improving vision",and the application of the regulating qi and improving vision acupoint formula has shown good efficacy.The article also expounded the acupoint selection rules and basis from the perspective of meridian syndrome differentiation,in order to provide reference for the selection and compatibility of acupoints for amblyopia.

Objective:Investigate the impact of calcification on the long-term outcomes of patients with coronary chronic total occlusion (CTO) after percutaneous coronary intervention (PCI).Methods:A retrospective cohort study was conducted. Patients who underwent PCI and had at least one CTO lesion at Fuwai Hospital between January 2010 and December 2013 were consecutively enrolled. Calcification was evaluated by coronary angiography, and patients were divided into two groups: moderate/severe calcification group and non/mild calcification group. Clinical follow-up was completed up to 5 years. Incidence of PCI-related complications and immediate procedural outcomes were compared between two groups, and the primary endpoint was the target lesion failure (TLF) at 5 years after PCI. Clinical follow-up endpoint events were analyzed using Kaplan-Meier survival analysis with log-rank test, and Cox multivariate regression model was used to evaluate the relationship between calcification and TLF.Results:The study included 2 659 CTO patients with an age of (57.2±10.5) years, of whom 442 (16.6%) were female, and among whom 13.5% (360/2 659) had moderate/severe calcification. Compared with the non/mild calcification group, the moderate/severe calcification group had a higher incidence of PCI-related complications (43.2% (156/361) vs. 32.5% (772/2 374), P<0.001) and procedural failure (34.3% (124/361) vs. 24.3% (577/2 374), P<0.001). Additionally, the moderate/severe calcification group showed a higher risk of the primary endpoint event (TLF) during the 5-year follow-up (19.8% vs. 15.3%, log-rank P=0.028). Higher incidence of cardiac death was observed in moderate/severe calcification group (5.7% vs. 2.7%, log-rank P=0.003). Cox multivariate regression analysis revealed that moderate/severe calcified plaques remained an independent risk factor for 5-year TLF after CTO-PCI ( HR=1.34, 95% CI: 1.01-1.79, P=0.043). Conclusion:Compared with CTO patients with non/mild calcification, those with moderate/severe calcification have higher procedural failure and complication rates, as well as poorer long-term prognosis, mainly due to an increase in cardiac death.

Objective:To explore the structural relationship between WMSDs in the upper limbs and various risk factors in the occupational population in China, based on a large sample epidemiological survey and structural equation analysis, and to establish a structural equation model, so as to lay a foundation for the prevention and control of such diseases.Methods:The Chinese version of the Musculoskeletal Disorders Electronic Questionnaire was used to conduct a nationwide survey on the prevalence of WMSDs in the upper extremity. Six factors related to WMSDs in the upper extremity were extracted by the classification standard of adverse ergonomic factors and their source and confirmatory factor analysis, including work organization, work type, upper extremity work posture, individual factors, upper extremity fatigue and upper extremity WMSDs. The structural equation analysis was carried out and the structural equation model was established.Results:The incidence of WMSDs and fatigue in the upper limbs was 24.44% and 43.76%, respectively. The adjusted structural equation model fitting indicators were generally up to the standard (GFI=1.000, AGFI=1.000, RMSEA=0.043, NFI=0.808, TLI=0.784) . The four exogenous latent variables of work organization, work type, upper limb work posture and individual factors were correlated. There was a strong positive correlation between job type and upper limb work posture ( r=0.865) , a moderate positive correlation between work organization and job type and upper limb work posture ( r=0.570, 0.490) , and a weak negative correlation between individual factors and the other three exogenous latent variables. Upper limb work posture and individual factors had direct effects on upper limb WMSDs, and the effect coefficients were 0.10 and 0.06, respectively. Upper limb fatigue played a mediating role between work organization, work type, upper limb work posture and upper limb WMSDs. The effect coefficient was 0.46, and the composition ratios of indirect effects were 100.0%, 100.0%, and 38.3%, respectively. The direct path effect of upper limb work posture, individual factors and upper limb WMSDs was weaker than the mediating path through upper limb fatigue. Conclusion:When carrying out the prevention and control of upper limbWMSDs, it is necessary to comprehensively consider the pathogenesis path of upper limb muscle fatigue and upper limb WMSDs caused by work organization, work type, and upper limb work posture, so as to provide theoretical reference for improving the prevention and control level of such diseases.

Objective:To observe the clinical efficacy of gentle moxibustion at different temperatures in treating people with diarrhea-predominant bowel syndrome(IBS-D)due to spleen deficiency.Methods:A total of 108 IBS-D patients were divided into two groups using the random number table method,with 54 participants in each group.Moxibustion group 1 received gentle moxibustion at(43±1)℃at bilateral Tianshu(ST25)and Zusanli(ST36),lasting 30 min each session;moxibustion group 2 received gentle moxibustion at(37±1)℃at the same points.Both groups received the intervention 3 times weekly for a total of 18 sessions.Abdominal pain intensity,stool form,pattern-based efficacy,quality of life,and mental health assessments were performed at weeks 0,3,6,and 8.Results:The total effective rate for abdominal pain intensity was 87.8%in moxibustion group 1 versus 51.1%in moxibustion group 2,and the difference was statistically significant(P<0.05).When the treatment finished,abdominal pain intensity,the Bristol score,IBS-symptom severity scale(IBS-SSS)score,self-rating anxiety scale(SAS)score,and self-rating depression scale(SDS)score dropped significantly in both groups(P<0.05),and the IBS-quality of life(IBS-QOL)score increased markedly(P<0.05).Between-group comparisons demonstrated that abdominal pain intensity,the Bristol general score,IBS-SSS score,traditional Chinese medicine(TCM)pattern score,and SDS score were significantly lower in moxibustion group 1 than in moxibustion group 2 at treatment week 6(P<0.05),and the IBS-QOL score was notably higher in moxibustion group 1(P<0.05).Conclusion:Whether at 43℃or 37℃,gentle moxibustion at Tianshu(ST25)and Zusanli(ST36)can improve abdominal pain,stool form,and quality of life,reduce disease severity,and mitigate TCM pattern in IBS-D patients;43℃gentle moxibustion performs better than 37℃gentle moxibustion in improving abdominal pain,stool form,disease severity,TCM pattern,quality of life,anxiety,and depression in IBS-D.
