AIM: To analyze the influencing factors of capsular constriction syndrome(CCS)in cataract patients after phacoemulsification(Phaco)combined with intraocular lens(IOL)implantation.METHODS: Retrospective study. The data of 2 900 cataract patients(2 900 eyes)in our hospital's information system from January 2021 to January 2024 were collected. All patients were treated with Phaco combined with IOL implantation, and the incidence of CCS within 30 wk after surgery was recorded. Patients were categorized into CCS(116 cases, 116 eyes)and N-CCS group(2 784 cases, 2 784 eyes)based on the occurrence of CCS. The basic data of the two groups were compared, and the influencing factors of CCS within 30 wk after Phaco combined with IOL implantation in cataract patients were analyzed by multivariate Logistic regression.RESULTS: Among 2 900 patients(2 900 eyes)included, 116 cataract patients(116 eyes)developed CCS within 30 wk after Phaco combined with IOL implantation, with an incidence rate of 4.00%. The single factor and multi-factor Logistic regression analysis showed that the complicated diabetes, high myopia, complicated glaucoma, and axial length(AL)>30 mm were the risk factors for the occurrence of CCS after Phaco IOL implantation in cataract patients(all P<0.05).CONCLUSION: Attention should be paid to cataract patients with diabetes, high myopia, glaucoma and AL>30 mm, which will increase the risk of CCS within 30 wk after Phaco combined with IOL implantation in cataract patients.

Objective: To construct a hypertension risk prediction model for residents aged 18-79 years, so as to provide an assessment tool for early screening and prevention of hypertension in high-risk groups. Methods: The permanent residents aged 18-79 years from 6 townships (streets) in Fangshan District of Beijing Municipality were selected as the study subjects using a multi-stage stratified random sampling method from March to June 2023. Demographic information, lifestyle, body mass index (BMI), blood pressure, fasting blood glucose, and blood lipid were collected through questionnaire survey, physical examination, and laboratory tests. Subjects were randomly divided into training and validation sets at a 7∶3 ratio. The logistic regression model was used to screen the risk factors of hypertension, and a hypertension risk prediction nomogram was constructed. Receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis were used to verify the discrimination, fit, and clinical application value of the model. Results: A total of 4 438 subjects were included, including 2 365 males (53.29%) and 2 073 females (46.71%), with a mean age of (44.99±14.90) years. The prevalence of hypertension was 35.29% (1 566 cases), and the standardized prevalence was 24.74%. The logistic regression model screened out 9 influencing factors of hypertension. The nomogram was established as ln[p/ (1-p)]= -2.873 + 0.935×40-<50 years + 1.463×50-<60 years + 1.908×60-<70 years + 2.346×70-79 years + 0.298×male-0.675×college degree or above + 0.384×smoking + 0.227×drinking + 0.572×overweight + 1.449×obesity + 0.557×heart rate ≥80 beats/min + 0.428×diabetes + 0.484×dyslipidemia. The area under the ROC curve of the validation set was 0.821 (95%CI: 0.798-0.843), and the calibration curve results showed that the calibration curve fitted the actual curve well. Decision curve analysis showed that the threshold probability was in the range of 0.10 to 0.70, and the model had good predictive value and clinical application value. Conclusion The nomogram based on age, gender, educational level, smoking, drinking, body mass index, heart rate, diabetes, and dyslipidemia can be used to predict the risk of hypertension among residents aged 18-79 years.

Objective:To investigate and analysis of the occurrence and influencing factors of sarcopenia in elderly critically ill patients in the intensive care unit (ICU).Methods:A prospective cohort study was conducted. Elderly patients (aged ≥ 60 years) admitted to the ICU of Tianjin Medical University General Hospital from November 2023 to June 2024 were enrolled. Clinical records were collected, and conduct muscle mass and strength measurements, as well as upper arm circumference and calf circumference were measured. Appendicular skeletal muscle index (ASMI) of less than 7.0 kg/m 2 for males and less than 5.7 kg/m 2 for females was defined as reduced muscle mass, grip strength of less than 28 kg for males and less than 18 kg for females was defined as decreased muscle strength, patients meeting both low muscle mass and low muscle strength criteria were diagnosed with sarcopenia. According to the diagnostic criteria for sarcopenia, patients were divided into sarcopenia group and non-sarcopenia group. Multivariate Logistic regression analysis was applied to identify risk factors for sarcopenia in the elderly and to develop a predictive model for the occurrence of sarcopenia. The predictive value of various risk factors for sarcopenia in elderly critically ill patients were evaluated by receiver operator characteristic curve (ROC curve). The Kaplan-Meier curve for the length of ICU stay of two groups patients were drawn. Results:Finally, 540 elderly critically ill patients were included, including 43 patients with sarcopenia, and the incidence of sarcopenia was 8.0%. Univariate analysis showed that there were significantly differences in body mass index (BMI), number of hospitalizations in the past year, the length of ICU stay, ventilation mode, duration of mechanical ventilation, pre-admission exercise habits, nutritional support methods, upper arm circumference, calf circumference, and albumin infusion between the sarcopenia group and the non-sarcopenia group. Multivariate Logistic regression analysis showed that BMI [odds ratio ( OR) = 0.79, 95% confidence interval (95% CI) was 0.67-0.93, P = 0.004], calf circumference ( OR = 0.64, 95% CI was 0.54-0.76, P < 0.001), and duration of mechanical ventilation ( OR = 1.06, 95% CI was 1.01-1.12, P = 0.034) were associated with an increased risk of sarcopenia in elderly critically ill patients. The ROC curve results showed that the area under the curve (AUC) and 95% CI of BMI, calf circumference, and duration of mechanical ventilation for predicting sarcopenia in elderly critically ill patients were 0.828 (0.767-0.888), 0.889 (0.844-0.933), and 0.397 (0.299-0.496), respectively, with cut-off values of 22.95 kg/m 2, 28.25 cm, and 50.50 days, respectively. The Kaplan-Meier curve showed that the cumulative survival rate of patients with sarcopenia was significantly lower than that of the non-sarcopenia group (Log-Rank test: χ 2 = 5.619, P = 0.018). Conclusion:Lower BMI, smaller calf circumference, and longer duration of mechanical ventilation are associated with an increased risk of sarcopenia in critically ill elderly patients.

Objective To investigate the effect of rehabilitation instruction based on resourceful theory on the execution intention of exercise behaviour in patient with the first-episode stroke.Methods From September 2022 to February 2023,a total of 80 inpatients with first-episode stroke from a general hospital in Anhui Province participated in the study.Patients in Wards Ⅰ and Ⅱ were assigned to an intervention group,while those in Wards Ⅲ and Ⅳ were assigned to a control group,with 40 patients per group.The patients in control group received standard interventions,while those in the intervention group were offered with a rehabilitation instruction based on resourceful theory in addition to the standard interventions.Stroke patient rehabilitation exercise behaviour execution intention questionnaire,resourcefulness scale and modified Barthel were employed for assessments before and after the intervention.Results After the intervention,the intervention group showed significantly higher scores inexecutive intention of exercise behaviour,resourcefulness level and daily living activities compared to those in the control group(all P＜0.01).Conclusion Rehabilitation instruction based on the theory of resourcefulness can effectively increase the executive intention of exercise behaviour in the patients with first-episode stroke,improve the resourcefulness thinking levels and enhance the daily living activity of the patients.

Objective:To compare the consistency of lymphoma multigene detection panels based on next-generation sequencing (NGS) with FISH detection of B-cell lymphoma gene rearrangement.Methods:From January 2019 to May 2023, fusion genes detected by lymphoma-related 413 genes that targeted capture sequencing of 489 B-cell lymphoma tissues embedded in paraffin were collected from Henan Cancer Hospital, and the results were compared with simultaneous FISH detection of four break/fusion genes: BCL2, BCL6, MYC, and CCND1. Consistency was defined as both methods yielding positive or negative results for the same sample. The relationship between fusion mutation abundance in NGS and the positivity rate of cells in FISH was also analyzed.Results:Kappa consistency analysis revealed high consistency between NGS and FISH in detecting the four B-cell lymphoma-related gene rearrangement ( P<0.001 for all) ; however, the detection rates of positive individuals differed for the four genes. Compared with FISH, NGS demonstrated a higher detection rate for BCL2 rearrangement, a lower detection rate for BCL6 and MYC rearrangement, and a similar detection rate for CCND1 rearrangement. No correlation was found between fusion mutation abundance in NGS and the positivity rate of cells in FISH. Conclusions:NGS and FISH detection of B-cell lymphoma gene rearrangement demonstrate overall good consistency. NGS is superior to FISH in detecting BCL2 rearrangement, inferior in detecting MYC rearrangement, and comparable in detecting CCND1 rearrangement.

Objective:To construct and test the reliability and validity of an assessment scale for self-management of patients with dry eye, so as to help patients establish dry eye related health behaviors.Methods:Based on the knowledge attitude and practice theory, the initial scale was constructed on the basis of literature review and qualitative interview, and revised through Delphi expert consultation and expert argumentation. After the preliminary investigation, 211 dry eye patients treated in the dry eye nursing outpatient department of Beijing Tongren Hospital from August 2023 to January 2024 were selected by convenience sampling method for questionnaire investigation to test the reliability and validity of the scale.Results:Among 211 dry eye patients, there were 58 males and 153 females, aged (39.31 ± 12.81) years old. The scale of self-management of patients with dry eye included 27 items in 3 dimensions: knowledge, attitude and behavior. The authority coefficient of the two rounds of expert consultation was 0.86, and the Kendall coordination index increased from 0.175 to 0.223 (both P < 0.01). The cumulative variance contribution rates of the three dimensions were 41.843%, 54.219% and 44.273%, respectively. The Cronbach α coefficient of the scale was 0.787, and the Spearman-Brown coefficient was 0.641. Conclusions:The scale of self-management of patients with dry eye has good reliability and validity and can be used in the assessment of dry eye patients to provide a reference basis for targeted guidance and intervention.

This article reviews the application status and prospect of endoscopic technology in surgical treatment of breast cancer.

Background Job burnout has become an important factor affecting the mental and physical health and work efficiency of college counselors, and indirectly affects the quality and development of talent cultivation for college students. Objective To explore the relationship between job stress, job crafting, and job burnout among college counselors, and to test the mediating role of job crafting between job stress and job burnout, in order to take targeted measures to alleviate job stress and job burnout of college counselors, reduce associated health risks, and improve the effectiveness of higher education. Methods An anonymous questionnaire survey was conducted among 400 counselors from social network communication groups by convenience sampling. The Counselor Work Stress Scale, Job Crafting Scale, and Maslach Burnout Inventory-General Survey were used. Harman's single-factor method was used to evaluate common method bias in the survey data. One-way ANOVA was applied to test the difference in job stress, job crafting, and job burnout among college counselors by demographic characteristics, and chi-square test was used to analyze the difference in reporting job burnout. Partial correlation analysis was used to evaluate the correlation between selected variables. Structural equation modeling was used to analyze the relationship of job stress, job crafting, and job burnout among college counselors, and Bootstrap analysis was used to test if there was a mediating effect of job crafting on the relationship between job stress and job burnout. Results Of the 390 questionnaires recovered, there were 338 valid questionnaires (86.67%). Among the included subjects, the mean scores of job stress, job crafting, and job burnout were (2.70±0.62), (3.77±0.62), and (2.09±1.09), respectively. The positive rate of job burnout was 76.9% (260/338), with a positive rate of 72.8% in exhaustion dimension and 59.8% in cynicism dimension. There were significant differences in job crafting scores among the college counselors by different genders and professional titles (P<0.05). Female counselors had significantly higher job burnout scores and positive rates than male counselors (P<0.05). The partial correlation analysis showed that job stress, work load, school evaluation and expectation, and interpersonal relationship were positively correlated with job burnout (r=0.562, 0.442, 0.473, and 0.455, respectively, P<0.01), and negatively correlated with job crafting (r=−0.271, −0.169, −0.246, and −0.247, respectively, P<0.01); job crafting, cognitive crafting, relationship crafting, and task crafting were negatively correlated with job burnout (r=−0.447, −0.452, −0.366, and −0.340, respectively, P<0.01). The modified structural equation modeling indicated that job stress negatively affected job crafting (b=−0.348, P<0.001) and positively affected job burnout (b=0.454, P<0.001); job crafting negatively affected job burnout (b=−0.459, P<0.001), and played a partial mediating role in the relationship between job stress and job burnout, and the effect value was 0.160 (95%CI: 0.102, 0.230) that accounted for 26.10% of the total effect. Conclusion Job burnout among the college counselors is prominent. Job crafting presents an inhibitory effect on job burnout. Job stress indirectly affects the occurrence of job burnout by inhibiting the generation of job crafting.
