ObjectiveTo compare colonoscopy compliance rates under different screening strategies, to explore ways to enhance colonoscopy compliance among residents with colorectal carcinoma. MethodsResidents aged between 50‒80 years were recruited through extensive community outreach and voluntary participation. A total of 210 630 residents who participated in the colorectal carcinoma screening program in Jiading District, Shanghai, between 2013 and 2019 were selected as the research subjects. All subjects underwent a colorectal carcinoma risk assessment questionnaire survey and two fecal occult blood tests (FOBT). Positive results in the initial screening were defined as a positive questionnaire survey or a positive result in at least one FOBT. Participants with positive initial screening results were advised to undergo colonoscopy screening in a hospital. Colonoscopy results were collected from hospital reports and physician follow-ups. Compliance with colonoscopy was analyzed under different screening strategies to identify possible factors influencing residents’ willingness to undergo the procedure. ResultsA total of 21 403 individuals (10.16%) were identified as positive with the questionnaire survey, 31 595 individuals (15.00%) tested positive with at least one FOBT. Combined questionnaire and FOBT positivity was observed in 3 501 individuals (1.66%). Among the 48 453 individuals with positive initial screening results, 17 230 (35.56%) underwent colonoscopy, and a total of 315 cases of colorectal cancer were detected. The sensitivity, specificity value of FOBT initial screening were 83.81% and 84.66%, respectively. According to the combined risk assessment and FOBT initial screening preliminary screening, the lowest colonoscopy compliance rate (25.63%) was observed among individuals with only a positive questionnaire, and the highest compliance rate (52.55%) was among those with both positive questionnaire survey and two positive FOBT results. Multivariate analysis revealed that FOBT positivity had the greatest impact on colonoscopy compliance. Those with one positive FOBT test result were 2.64 times more likely to undergo colonoscopy screening than those with negative FOBT results, while individuals with two positive FOBT results were 3.18 times more likely to do so. After adjusting for FOBT results, individuals with positive questionnaire survey results were 1.43 times more likely to undergo colonoscopy screening than those with negative results (95%CI: 1.34‒1.52). Compared to questionnaire-based risk assessment, FOBT results were more influential in determining compliance with colonoscopy. ConclusionThe choice of initial screening method significantly impacts residents’ compliance with colonoscopy. While implementing colorectal carcinoma screening programs, it is necessary to strictly adhere to screening protocols, including risk assessment and FOBT. Additionally, efforts should be made to raise public awareness, encouraging residents to actively participate in risk assessments and FOBT, thereby improving their compliance with colonoscopy.

AIM:To observe the clinical efficacy of vitrectomy at different times for open ocular trauma and explore the timing of stage Ⅱ vitrectomy.METHODS: Retrospective case series study. A total of 60 cases(60 eyes)with open ocular trauma who visited our ophthalmology department from June 2022 to February 2023 were included. They were divided into treatment group A(interval ≤14 d)and treatment group B(interval >14 d)based on the interval between the stage Ⅰ emergency treatment surgery and the stage Ⅱ vitreoretinal surgery. Among the 32 cases(32 eyes)in the treatment group A, 16 eyes(50%)had eyeball rupture, 13 eyes(41%)had penetrating injury, and 3 eyes(9%)had perforating injury. Among the 28 cases(28 eyes)in the treatment group B, 15 eyes(54%)had eyeball rupture, 12 eyes(43%)had penetrating injury, and one eye(4%)had perforating injury. The two groups of patients were followed-up for 6 mo after surgery, and the treatment effects were compared.RESULTS:There was no statistically significant difference in visual acuity between the two groups of patients before vitrectomy(P>0.05). In the treatment group A, 10 eyes(31%)had significantly improved visual acuity, 21 eyes(66%)had effectively enhanced visual acuity, and 1 eye(3%)had no improvement in visual acuity at 6 mo after surgery. Among the 28 eyes in the treatment group B, 5 eyes(18%)had significantly improved vision, 16 eyes(57%)had effectively enhanced vision, and 7 eyes(25%)had no change in vision, with statistically significant difference between the two groups(U=322.5, P=0.032). There was no significant difference between the treatment group A and the treatment group B in complications such as secondary glaucoma, silicone oil dependence, vitreous hemorrhage, and eyeball atrophy(P>0.05). There was no evidence of traumatic proliferative vitreoretinopathy(TPVR)in the treatment group A during postoperative follow-up, which was significantly lower than that of the treatment group B(P<0.05).CONCLUSION:The prognosis of the stage Ⅱ vitrectomy for open ocular injury is relatively good after completing the stage Ⅰ surgery within 2 wk.

ObjectiveTo evaluate the intervention effect of meteorological risk forecasting service on acute onset and medical expenses of chronic obstructive pulmonary disease（COPD） patients， and to provide scientific basis for the establishment of health management model for chronic obstructive pulmonary disease（COPD） patients. MethodsStudy subjects were recruited from chronic obstructive pulmonary patients aged ≥40 in Pudong New Area. Propensity score matching method was used to determine the intervention group and the control group. The control group received regular health education and follow-up management， and the intervention group was provided with meteorological and environmental risk forecasting services through WeChat， mobile phone short message service（SMS）and telephone. Finally， a total of2 589 subjects were included in the analysis， including 1 300 in the intervention group and 1 289 in the control group. General demographic data， past medical history and family history of COPD， COPD related knowledge and practice survey， COPD related symptom assessment， acute onset， health service utilization and medical expenses before and after intervention were collected through questionnaire survey. The differences of acute attack， health service utilization and related medical expenses between the two groups before and after intervention were compared to evaluate the intervention effect. ResultsIn terms of acute attacks， after intervention， the incidence of acute attacks in the intervention group was lower than that before intervention（χ²=52.901， P<0.001）， and the incidence of acute attacks in the groups with different intervention methods was lower than that before intervention （P<0.001）. WeChat had the best effect， decreasing the incidence by 14.4%， followed by mobile phone SMS SMS decreasing by 12.3%. In terms of utilization of health services， the outpatient rate due to acute attack was lower in the intervention group after intervention than that before intervention （χ²=7.129， P=0.008）， and the outpatient rate due to acute attack was lower in the subjects who received the forecast service through mobile phone SMS than that before intervention （χ²=4.675， P<0.001）. In terms of medical expenses， there was no significant difference between control group and intervention group with different intervention methods before intervention （P>0.05）. After intervention， the difference between the control group and the intervention group with different intervention methods was statistically significant （H=11.864， P<0.05）. The results of multiple comparisons showed that compared with the control group， the average annual medical expenses of patients receiving mobile phone SMS and telephone forecasting services after intervention were lower than those of the control group， and the difference was statistically significant （P<0.05）. ConclusionMeteorological risk forecasting service can reduce the acute onset of COPD， reduce the rate of consultation and medical expenses due to acute onset， and provide scientific basis for the basic COPD health management model.

Objective To explore the relationship between baseline urinary protein levels and the onset of chronic obstructive pulmonary disease (COPD). Methods A questionnaire survey, blood and urine sample collection, physical examination, and pulmonary function test were conducted among permanent residents over 40 years old in Pudong New Area, Shanghai. The subjects were divided into four groups based on the baseline urine albumin-to-creatinine ratio (ACR) quartiles (0~1.65 mg/g, 1.65~4.89 mg/g, 4.89~10.78 mg/g, and ≥10.78 mg/g). Cox regression analysis was used to explore the relationship between ACR levels and the incidence of COPD in middle-aged and elderly people. Results Among the 3 105 subjects, the median follow-up time was 3.212 years (P25~P75：3.102~3.473). 116 new cases of COPD were observed, with an incidence density of 10.423 per 1000 person-years. The incidence densities for COPD at four ACR levels were 7.922 per 1 000 person-years, 8.300 per 1 000 person-years , 11.419 per 1 000 person-years, and 13.843 per 1 000 person-years, respectively. Cox regression analysis revealed that as the ACR level increased, there was a rising trend in the incidence rate of COPD (χ²=4.396, P=0.036). After adjusting for gender, age, education level, occupational exposure to dust, history of childhood pneumonia, smoking, family history of COPD, central obesity, and hypertension, the risk of developing COPD was 2.499 times higher (95% CI: 1.460~4.276) for ACR levels ≥10.78 mg/g compared to the reference group with a baseline ACR level of 0~1.65 mg/g. Conclusion Elevated ACR levels in middle-aged and elderly population may increase the risk of COPD, and early monitoring of urine protein levels is beneficial for COPD prevention.

ObjectiveTo understand the usage of antibiotics in outpatients in a county of Zhejiang Province from 2015 to 2020， so as to provide a basis for further standardizing the clinical application of antibiotics in this region. MethodsOutpatient records and prescription records of 146 public medical institutions from 2015 to 2020 were extracted from the electronic medical record data sharing platform system of medical institutions in a county of Zhejiang Province. The utilization rates and the number of types of antibiotics used in outpatient patients were described. According to the drug anatomy， therapeutic and chemical classification system （ATC）， clinical application classification and dosage form， the use status of different types of antibiotics was observed. The annual percentage change （APC） was used to analyze the time trend of antibiotic use. Among the antibiotic prescriptions in each year， the proportions of prescriptions aimed for different use reasons and patients were compared to analyze the changes in the structures of antibiotic prescriptions. ResultsDuring 2015‒2020， a total of 2 861 438 prescriptions were issued in146 primary public medical institutions in this county， including 314 642 prescriptions for antibiotics， and the overall utilization rate of antibiotics was 11%. The utilization rate of antibiotics showed a decreased trend across the years （from 14.23% in 2015 to 7.59% in 2020，APC=-11.51%， 95%CI=-0.01%‒-21.7%， t=-12.05， P<0.001） and an obvious seasonal variation character （higher in winter and spring， lower in summer and autumn）. Cefoxitin sodium for injection was the most used antibiotic in 2015， and cefuroxime was the most used antibiotic from 2015 to 2020， respectively. The utilization rates of cephalosporins （APC=-11.06%， 95%CI=0‒-20.89%， t=-22.233， P<0.001）， quinolones （APC=-9.74%， 95%CI=0‒-18.53%， t=-7.652， P=0.002）， macrolides （APC=-17.52%， 95%CI=0‒-17.52%， t=-3.626， P=0.022） and lincoamides （APC=-49.01%， 95%CI=0‒-74%， t=-3.35， P=0.029） showed a decreasing trend across the years. There were differences in the distribution of drug use reasons （χ²=9 458.427， P<0.001）， as well as the age （χ²=5 421.709， P<0.001） and sex （χ²=245.322， P<0.001） of patients. During the observation period， 50.69% of antibiotic prescriptions were used to treat respiratory diseases， with the highest proportion of 57.67% in 2015 and the lowest proportion of 34.93% in 2020. 58.37% of patients were aged 50‒70 years， with a decreasing proportion of patients under 50 years （17.83% in 2015， 6.64% in 2020） and an increasing proportion of patients over 70 years （24.1% in 2015， 38.41% in 2020）. ConclusionThe utilization rate of antibiotics used in outpatients from primary public medical institutions in a county of Zhejiang Province shows a decreasing trend across the years， but higher than that of secondary and above hospitals in China， and also higher than that of primary medical institutions in economically-developed areas. The management and monitoring of the clinical use of antibiotics in the county should be actively strengthened.

AIM:To summarize the clinical features and prognostic factors of patients with open ocular trauma in northwest China, and to explore the application of ocular trauma score(OTS)in open ocular trauma.METHODS:The clinical data of 91 patients(91 eyes)with open ocular trauma admitted to Xijing Hospital from June 2021 to June 2023 were retrospectively analyzed. The correlation analysis of visual acuity prognosis was carried out by age, treatment time, initial visual acuity, trauma zone and other factors, and the relationship between different OTS and prognostic visual acuity was discussed.RESULTS:Univariate analysis showed that age(0-20 years), treatment time(<24 h), initial visual acuity, trauma zone, trauma type(penetrating injury), anterior chamber hematoma, vitreous hematoma were correlated with prognostic visual acuity(all P<0.1); multivariate Logistic regression analysis showed that initial visual acuity and treatment time(<24 h)were risk factors(both P<0.05). There was a significant correlation between different OTS and prognostic visual acuity(rs=0.639,P<0.001).CONCLUSION:Patients with open ocular trauma should be diagnosed and treated as early as possible. The main factors influencing the visual prognosis are age, treatment time, initial visual acuity, trauma zone, trauma type, anterior chamber hematoma and vitreous hematoma. OTS has good application value in visual acuity evaluation of open ocular trauma prognosis.

ObjectiveTo explore the characteristics and major factors influencing mental health literacy (MHL) among non-graduating middle school and high school students in Taizhou, Zhejiang Province, and to provide a reference for the promotion of mental health literacy among adolescents. MethodsFrom September to October 2023, a stratified random cluster sampling method was used to conduct a questionnaire survey among students from three classes each in non-graduating grades in four middle schools and four high schools in Taizhou, Zhejiang Province. The survey included basic demographic information, a Structured Mental Health Literacy Questionnaire (MHLQ), and other psychological scales [Educational Stress Scale for Adolescents (ESSA), Perceived Choice Single Scale (PC), Child Depression Inventory (CDI), Generalized Anxiety Disorder (GAD), The University of California at Los Angeles 3-item Loneliness Scale (UCLA-3) and Multidimensional Scale of Perceived Social Support (MSPSS)]. t-tests, chi-square tests, analysis of variance (ANOVA), and multiple linear regressions were applied for the statistical analysis of the data. ResultsThe mental health literacy average score of 2 094 students was (82.3±15.8) points, with a mean of (4.1±0.8) points. The dimension of belief in mental health rights had the highest score. There were significant differences in the mental health literacy score across different dimensions for students with different household registration, economic levels, academic performance, and father’s education level (P<0.001). Multiple linear regression analysis indicated that rural household registration, lower paternal education level, greater academic pressure, a weaker sense of control over one’s behavior, less social support, and symptoms of loneliness, depression, or anxiety were associated with poorer mental health literacy among the students. ConclusionThe mental health literacy of middle school and high school students in Taizhou is generally good, but there are differences among students with different characteristics. Targeted interventions should be carried out for students from rural areas, with poorer mental health, and less low social support to improve the overall mental health literacy of adolescents.

Objective To analyze the refractive prediction error(PE)in combined vitrectomy,phacoemulsification,and intraocular lens(IOL)implantation for patients with macular disease and cataract.Methods This study encom-passed 96 patients(96 eyes)diagnosed with macular disease and cataract,who underwent combined vitrectomy,phacoe-mulsification and IOL implantation at the Department of Ophthalmology in Xijing Hospital,Air Force Military Medical Uni-versity from May 2014 to November 2022.The best corrected visual acuity(BCVA)and actual spherical equivalent(SE)were studied,PE and absolute refractive error(ARE)were calculated,and the correlations between PE and axial length(AL),anterior chamber depth(ACD),lens thickness(LT),flat keratometry(Kf),steep keratometry(Ks),mean kera-tometry(Km),corneal astigmatism degree(cylinder,Cyl),intraocular pressure(IOP),BCVA,corneal astigmatism axis,the classification of macular diseases,and the type of intraoperative vitreous fillers were analyzed.Results In the early postoperative period(within 3 days after surgery),no statistically significant disparity in BCVA was observed compared to preoperative data among the 96 patients studied(P＞0.05).The ARE was determined to be(1.47±2.54)D,indicating a substantial deviation between the actual SE and preoperative predictive refraction of the 96 patients(P＜0.05).Among them,61 patients had a myopic shift,35 patients had a hyperopic shift,and the values of PE were(-1.81±3.07)D and(0.87±0.96)D,respectively.At the 1-month mark after surgery,there was no statistically significant difference in BCVA compared to the preoperative data of 12 follow-up patients(P＞0.05).Similarly,no statistically significant differences were found between every two of the three data,namely the actual SE one month after surgery,the preoperative predictive refraction,and the actual SE in the early postoperative period of the 12 follow-up patients(all P＞0.05).Also,no disparity was observed in BCVA at the last follow-up(P＞0.05)among the 6 patients who were followed up for over 1 year(long-term postoperative follow-up).The correlation analysis revealed that,in the early postoperative period,the PE of patients with myopic shift was negatively correlated with both preoperative AL and Cyl measurements(both P＜0.05).The early postoperative PE of patients with myopic shift was associated with the diagnostic classification of macular diseases(P＜0.05),and the degree of myopic shift was observed to be significantly greater in patients with pathological myopia macular holes compared to those with other macular diseases(P＜0.05).Additionally,the early postoperative PE of patients with myopic shift was uncorrelated with preoperative ACD,TL,Kf,Ks,Km,IOP,BCVA,the type of intraoperative vitreous fillers and the corneal astigmatism axis(all P＞0.05).In contrast,for patients exhibiting hyperopic shift,the PE observed in the early postoperative period exhibited a positive correlation with preoperative Cyl(P＜0.05).PE was also correlated with the type of intraoperative vitreous fillers(P＜0.05),and the degree of hyperopic shift was notably enhanced when the intraoperative vitreous cavity was filled with silicone oil(P＜0.05).The PE of patients with hyperopic shift observed in the early postoperative period exhibited no correlation with preoperative AL,ACD,TL,Kf,Ks,Km,IOP,BCVA,the diagnos-tic classification of macular diseases or the astigmatism axis(all P＞0.05).Conclusion Refractive prediction error may occur in patients with macular disease and cataract in the initial postoperative period after the vitrectomy combined with phacoemulsification and IOL implantation,predominantly caused by myopic shift.However,over time,there is a signifi-cant reduction in the magnitude of this refractive error.The direction and extent of diopter drift appear to be influenced by preoperative AL,Cyl,the specific diagnosis of macular disease,and the type of vitreous cavity filler utilized in the surgical procedure.

Objective:To investigate the effects of compound Duzhong Jiangu Granules on joint function and gut microbiota in patients with Kashin-Beck disease.Methods:A single group pre- and post-experimental design was conducted, the patients with Kashin-Beck disease were selected as the subjects in Xunyi County, Xianyang City, Shaanxi Province; and treated with oral administration of compound Duzhong Jiangu Granules (12 g/bag, 1 bag/time, 3 times/day) for a period of 1 month. The improvement of joint function was evaluated using the joint dysfunction index scoring method before and after treatment. Morning stool samples of patients were collected and the changes in gut microbiota were analyzed before and after treatment using 16S rDNA sequencing technology.Results:A total of 87 patients with Kashin-Beck disease were included, including 44 males and 43 females; the age was (60.38 ± 7.12) years old, and the body mass index was (23.67 ± 3.59) kg/m 2. The comprehensive scores of joint dysfunction index for patients with Kashin-Beck disease before and after treatment were (7.27 ± 2.05) and (5.86 ± 2.01) points, respectively, and the difference was statistically significant ( t = 5.88, P < 0.001). The sequencing results of gut microbiota showed that there were statistically significant differences in the alpha diversity (chao1, observed species index) and beta diversity of gut microbiota in patients with Kashin-Beck disease before and after treatment ( Z = - 5.08, - 5.03, R = 0.09, P < 0.001). In the distribution of gut microbiota, Firmicutes was the dominant phylum, with relative abundances of 50.21% and 52.09% before and after treatment, respectively; the Bifidobacterium was the dominant bacterial genus, with relative abundances of 16.83% and 18.81% before and after treatment, respectively. At the genus level, a total of 17 gut microbiota genera were screened out, among which the relative abundances of Hafnia-Obesumbacterium, Gammaproteobacteria_unclassified, Acinetobacter, Pantoea, Leuconostoc, and Akkermanisia were significantly higher than before treatment ( Z = - 2.40, - 2.24, - 2.06, - 3.59, - 2.24, - 2.11, P < 0.05). The relative abundances of Dubosiella, Selenomonas, Anaeroplasma, Lachnospiraceae_ NK4A136_group, Rikenella, Prevotella, Megasphaera, Lactobacillus, Prevotella-9, Phascolarctobacterium, and Desulfovibrio were significantly lower than before treatment ( Z = - 9.38, - 2.61, - 2.18, - 8.43, - 2.45, - 2.46, - 2.49, - 7.29, - 2.29, - 2.55, - 2.08, P < 0.05). Conclusions:Compound Duzhong Jiangu Granules can effectively improve the joint function of patients with Kashin-Beck disease, and alter the diversity and richness of the gut microbiota community. It may reduce clinical symptoms in patients by regulating the structure of gut microbiota.
