AIM: To compare the efficacy of simple autologous blood coverage with ILM flap tamponade combined with autologous blood coverage after pars plana vitrectomy(PPV)with internal limiting membrane(ILM)peeling in treating macular hole retinal detachment(MHRD)of high myopia patients with moderately long axial length.METHODS: This retrospective study enrolled 45 patients(45 eyes)with high myopia and MHRD, and axial lengths of 26-29 mm treated at our institution between January 1, 2020 and January 1, 2024. Patients were divided into two groups based on surgical technique: group A(24 eyes)underwent PPV with ILM peeling, ILM flap tamponade, autologous blood coverage, and silicone oil injection; group B(21 eyes)received PPV with ILM peeling followed by autologous blood coverage and silicone oil injection. Intraocular pressure, best-corrected visual acuity(BCVA), retinal reattachment and macular hole closure status were compared at 1 wk, 1, 3, and 6 mo postoperatively. Silicone oil removal was performed at 6 mo postoperatively, with additional 2-month follow-up.RESULTS:At 8-month postoperative follow-up, both groups achieved complete retinal reattachment. Macular hole closure rates showed no significant intergroup difference(88% vs 86%, P=0.860). Significant improvement in BCVA was observed in both groups compared to preoperative values, with the group B demonstrating better visual outcomes than the group A(P<0.001). Transient parafoveal subretinal fluid persistence was noted in 2 eyes of the group A(resolved spontaneously at 5 and 8 mo post-PPV, respectively), and 1 eye of the group B(resolved by 4 mo post-PPV). Serial optical coherence tomography(OCT)monitoring revealed no macular hole reopening, with complete subretinal fluid resolution confirmed in all cases at final follow-up.CONCLUSION:For high myopic MHRD patients with moderately long axial length, both surgical approaches effectively promote macular hole closure and retinal reattachment. However, the autologous blood coverage technique demonstrates better BCVA than the combined ILM tamponade.

Objective:To investigate the satisfaction levels of the rural elderly in Dafeng district of Yancheng, Jiangsu province with the contracted family doctor services, and to identify the factors that influence their satisfaction.The findings of this study will provide valuable insights for improving the quality of the contracted family doctor services offered to the rural elderly population.Methods:The study utilized the stratified cluster sampling method to select elderly individuals aged 60 years and above from Dafeng district, Yancheng city for a questionnaire survey.Specifically, the study focused on elderly individuals who had participated in contracted family doctor services for more than six months.The survey aimed to gather information on the elderly population's general situation, as well as their understanding, utilization, and satisfaction with contracted family doctor services.The satisfaction of contracted family doctor services was analyzed using the chi square test and multivariate Logistic regression to identify the influencing factors.Results:The study surveyed 385 elderly individuals from rural areas who had contracted family doctor services.The results showed that 88.3%(340/385)of respondents were satisfied with the services they received.Additionally, 99.2%(382/385)of those surveyed were aware of the contracted family doctor services, and 81.8%(315/385)had received basic medical services from their signed-up doctors.The results of a multifactor analysis that examined the factors influencing the overall satisfaction of elderly patients with their contracted family doctor services revealed several significant factors.Specifically, being female( OR=2.557, 95% CI: 1.122-5.830, P=0.026)and unmarried( OR=7.355, 95% CI: 1.850-29.237, P=0.005), supporting the contracted family doctor services system( OR=18.442, 95% CI: 1.732-195.973, P=0.016), believing that the contracted medical institutions had excellent hardware facilities( OR=9.918, 95% CI: 2.313-42.526, P=0.002)and providing high-quality health services for the elderly( OR=8.723, 95% CI: 1.556-48.908, P=0.014), as well as experiencing improved health status after signing the contract( OR=5.006, 95% CI: 1.764-14.201, P=0.002)were all significant factors influencing their satisfaction.These findings suggest that these factors are important considerations for improving the satisfaction of elderly patients with their contracted family doctor services. Conclusions:The contracted family doctor services provided in Dafeng district, Yancheng city have been well received by the rural elderly population.Factors such as gender, marital status, attitude towards the contracted family doctor services system, improvements in health status after contracting the service, quality of the hardware facilities at the contracted medical institution, and availability of health services specifically tailored for the elderly all play a role in determining the level of satisfaction among the contracted elderly population.To better serve the elderly population, it is crucial that we prioritize their needs.This can be achieved by improving the level of "suitable aging" in the contracted services and enhancing the satisfaction of family doctors who provide these services.

Objective:To analyze the correlation between fatty liver index (FLI) and myocardial remodeling.Methods:For cross-sectional study, cluster sampling was used to conduct a follow-up study of “Risk evaluation of cancers in Chinese diabetic individuals: A longitudinal (REACTION) study” among communities of Gucheng and Pingguoyuan of Beijing from April 2015 to September 2015. According to the inclusion and exclusion criteria, 8 848 participants were selected. Biochemical indicators such as body mass index, waist circumference, triglycerides, and γ-glutamyl transpeptidase were detected to calculate the FLI. The correlation between FLI and myocardial remodeling was analyzed. Interventricular septal thickness (IVS), left atrial diameter (LAD), left ventricular end diastolic diameter (LVEDD), and the presence of diastolic dysfunction were measured by color doppler ultrasound. The participants were divided into Q1 group (FLI<30, 4 529 cases), Q2 group (30≤FLI<60, 2 762 cases), and Q3 group (FLI≥60, 1 557 cases) based on FLI levels. Single factor analysis of variance was used for inter-group comparison, logistic regression analysis was used to analyze the correlation between FLI and myocardial remodeling.Results:A total of 8 848 subjects were selected for the study (3 110 male and 5 738 female, mean age: 59.96 years). The IVS of Q1, Q2, and Q3 groups were (9.35±1.08), (9.73±1.22), and (10.07±1.31) mm, respectively. The LAD were (30.94±3.90), (33.37±4.12), and (34.98±4.47) mm, respectively. The LVEDD were (42.51±5.05), (44.43±5.10), and (46.06±5.52) mm, respectively. All increased with the increase of FLI (all P<0.001). FLI was an independent risk factor for IVS thickening, LAD increase, LVEDD increase, and diastolic function decrease. The respective risks for IVS thickening, LAD increase, LVEDD increase, and diastolic function decrease in a population with intermediate and higher FLI levels was 1.62 times (95% CI 1.39-1.89) and 2.53 times (95% CI 2.13-3.00); 2.71 times (95% CI 2.39-3.06) and 5.00 times (95% CI 4.12-6.08); 2.36 times (95% CI 1.85-3.00) and 4.33 times (95% CI 3.33-5.62); and 1.90 times (95% CI 1.63-2.19) and 1.95 times (95% CI 1.60-2.37) than those with lower FLI levels. Conclusion:There is a certain relevance between FLI and myocardial remodeling.

Objective:To analyze the correlation between fatty liver index (FLI) and the outcomes of individuals with high normal blood pressure.Methods:In this retrospective cohort study, data from the follow-up population of the Beijing branch of the Risk Evaluation of Cancers in Chinese Diabetic Individuals: A Longitudinal (REACTION) study conducted from December 2011 to August 2012 were selected. Obtain indicators such as height, weight, waist circumference, fasting blood glucose, 2-h postprandial blood glucose, triglycerides, high-density lipoprotein cholesterol, and glutamyl transpeptidase were measured, and the FLI was calculated. The population with high normal blood pressure was divided into the FLI<30 group (1 822 cases); 30≤FLI<60 group (1 026 cases); and FLI≥60 group (473 cases) based on FLI levels. The blood pressure outcome data from the follow-up survey of this population from April 2015 to September 2015 were collected. Single factor analysis of variance was used for intergroup comparison, and logistic regression was used to analyze the correlation between FLI and the outcome of high normal blood pressure in the population.Results:The FLI was an independent influencing factor for their conversion to normal blood pressure (all P<0.01). Among all observed populations, the likelihood of conversion to normal blood pressure in the 30≤FLI<60 group and FLI≥60 group was 0.63 (95% CI 0.51-0.78) and 0.61 (95% CI 0.45-0.82) of the FLI<30 group, respectively. In the population of 40≤age<60 years, this likelihood was 0.60 (95% CI 0.47-0.76) and 0.57 (95% CI 0.41-0.79), respectively. FLI is not an independent influencing factor for the conversion to normal blood pressure in individuals aged over 60 years ( P=0.161). FLI is an independent risk factor for hypertension (all P<0.05). Among all observed populations and population of 40≤age<60 years and age>60 years, the risk of hypertension in the 30≤FLI<60 group and FLI≥60 group was 1.49 times (95% CI 1.23-1.80) and 1.54 times (95% CI 1.19-1.98); 1.41 times (95% CI 1.13-1.75) and 1.38 times (95% CI 1.04-1.83); and 1.75 times (95% CI 1.22-2.53) and 2.10 times (95% CI 1.24-3.58) of the FLI<30 group, respectively. Conclusions:There is a correlation between FLI levels and future outcomes of individuals with normal high blood pressure. Although people with higher FLI are more likely to develop hypertension, those with higher FLI are also less likely to develop normal blood pressure in the 40≤age<60-year group.

Objective:To investigate the intention to stay on among primary health care workers (PHWs) during the COVID-19 epidemics and its influencing factors.Methods:An online questionnaire survey was conducted among PHWs from 62 primary health institutions in 31 provinces, autonomous regions and municipalities across China selected by multi-stage whole cluster random sampling method between May and October 2022. According to the job position, the PHWs were divided into 5 categories: general practitioners (GPs), nurses, public health doctors, managers and support staff. Intention to stay was measured using the Chinese version of the Intention to Stay Questionnaire. Multiple linear regression model was used to analyze the influencing factors of the intention to stay in PHWs of different occupational categories, including personal factors, work factors, factors related to the COVID-19 and psychological reactions.Results:A total of 3 769 PHWs from 44 community health service centers, 18 township hospitals of 27 provinces/autonomous regions and 4 municipalities participated in this survey. The mean age of participants was (37.4±9.2) years, including 2 971(78.8%) women. The mean score of intention to stay of participants was 21.7±4.1. Compared with GPs, managers had lower intention to stay ( P=0.004). Age, female, in marriage, monthly income, years of primary care service, self-evaluation of unit support function, MSQ-SF score, and PA score were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 score, EE score, and DP score were negatively correlated with the score of intention to stay (all P<0.05). The MSQ-SF scores of all occupational categories were positively correlated with the scores of intention to stay (all P<0.01). In addition, among GPs, monthly income, years of service in primary care, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while PHQ-9 scores and EE scores were negatively correlated with the score of intention to stay (all P<0.05). Among nurses, age, female gender, monthly income, self-evaluation of unit support function, and PA score were positively correlated with the score of intention to stay (all P<0.05), while EE scores and retention will score were negatively associated with ( P<0.001). Among public health doctors, in marriage was positively correlated with the score of intention to stay ( P=0.018). Among managers, DP score was negatively correlated with the score of intention to stay ( P=0.001). Among support staff, female gender, monthly income, years of primary care service, self-evaluation of unit support function, and PA scores were positively correlated with the score of intention to stay (all P<0.05), while EE score and DP score were negatively correlated with intention to stay (all P<0.05). Conclusions:The intention to stay of PHWs in China during the COVID-19 was at an intermediate level, which was affected by many factors. Among them, job satisfaction was positively correlated with the intention to stay of all occupational categories, and the influencing factors of different occupational categories have some variations.

Objective:To investigate the value of soluble interleukin-6 (IL-6) receptor (sIL-6R) level in predicting ultrafiltration insufficiency in peritoneal dialysis (PD) patients.Methods:It was a prospective cohort study. The patients who received continuous ambulatory PD and regular follow-up between November 2016 and July 2018 in the PD Center of Renji Hospital, School of Medicine, Shanghai Jiao Tong University were enrolled. Enzyme-linked immunosorbent assay was used to determine dialysate sIL-6R and its appearance rate (AR) was calculated. Patients were divided into high sIL-6R AR group and low sIL-6R AR group according to median value of sIL-6R AR and prospectively followed up until death, PD cessation, or the end of the study (December 31, 2022). Multiple linear regression was used to analyze the related factors of sIL-6R AR. Kaplan-Meier method and log-rank test were used to compare the survival rate difference of ultrafiltration insufficiency between high sIL-6R AR group and low sIL-6R AR group. Multivariate Cox regression and multivariate competing risk models were used to assess the risk factors associated with occurrence of ultrafiltration insufficiency.Results:A total of 198 PD patients were enrolled, including 115 (58.1%) males, with age of (54.9±13.7) years old and PD duration of 22.5 (6.6, 65.0) months. The sIL-6R AR of the cohort was 2 094.7 (1 672.4, 2 920.9) pg/min. Compared with low sIL-6R AR（<2 094.7 pg/min）group, high sIL-6R AR（>2 094.7 pg/min）group had older age ( t=-3.269, P=0.001), higher body mass index ( t=-3.248, P=0.001), proportion of combined diabetes mellitus ( χ2=8.890, P=0.003), 24 h glucose exposure ( Z=-2.257, P=0.024), 24 h ultrafiltration capacity ( Z=-2.515, P=0.012), 4 h dialysate creatinine to serum creatinine ratio ( t=-2.609, P=0.010), mass transfer area coefficient of creatinine ( Z=-2.308, P=0.021), IL-6 AR ( Z=-3.533, P<0.001) and solute glycoprotein 130 AR ( Z=-8.670, P<0.001), and lower serum albumin ( t=2.595, P=0.010) and residual renal function ( t=2.133, P=0.033). Multiple linear regression analysis showed that body mass index ( β=0.194, P=0.005), serum albumin ( β=-0.215, P=0.002) and dialysate lg[IL-6 AR] ( β=0.197, P=0.011) were independently correlated with sIL-6R AR. By the end of the study, 57 (28.8%) patients developed ultrafiltration insufficiency. Kaplan-Meier analysis showed that high sIL-6R AR group had a significantly inferior ultrafiltration insufficiency-free survival rate than that in low sIL-6R AR group (log-rank χ 2=5.375, P=0.020). Multivariate Cox regression analysis and multivariate competing risk models showed that high dialysate sIL-6R AR (>2 094.7 pg/min) was an independent influencing factor of ultrafiltration insufficiency ( HR=2.286 , 95% CI 1.254-4.165 , P=0.007 ; SHR=2.074, 95% CI 1.124-3.828, P=0.020) in PD patients. Conclusions:Dialysate sIL-6R level was associated with body mass index, serum albumin and dialysate IL-6 level. Dialysate sIL-6R may be a predictive factor of ultrafiltration insufficiency in PD patients.

Objective To compare and analyze the tilt and decentration of the intraocular lens in patients receiving four-point and two-point suspension fixation,as well as their relationship with visual prognosis.Methods A total of 80 patients(80 eyes)who underwent intraocular lens suspension fixation at the Ophthalmology Department of Baoding No.1 Central Hospital from June 2021 to April 2022 were selected as the subjects.These patients were randomly divided into the experimental group(41 patients,41 eyes,underwent four-point suspension fixation)and the control group(39 patients,39 eyes,underwent traditional two-point suspension fixation).They were followed up for at least 6 months after surgery to re-cord their uncorrected visual acuity(UCVA)and best corrected visual acuity(BCVA)before surgery and at the last follow-up.The tilt angle and decentration distance of the intraocular lens of patients in the two groups were measured after surger-y by a panoramic ultrasound biomicroscope.The preoperative and last follow-up UCVA and BCVA of patients in the two groups,as well as tilt angle and decentration distance of the intraocular lens after surgery,were compared,and the corre-lation between tilt angle,decentration distance and postoperative UCVA,BCVA was analyzed by Person correlation analy-sis.Results The UCVA and BCVA at the last follow-up in the experimental group and control group were better than those before surgery(all P＜0.05).The difference in postoperative UCVA between the experimental group and the control group was statistically significant(t=-6.20,P=0.00),and the experimental group had better postoperative UCVA than the control group.There was no statistically significant difference in postoperative BCVA between the experimental group and the control group(t=-1.43,P=0.16).The postoperative horizontal and vertical tilt angles of the intraocular lens in the experimental group were 0.70°±0.24° and 0.60°±0.16°,respectively;while those in the control group were 2.66°± 1.40° and 3.76°±0.67°,respectively.The differences between the two groups were statistically significant(t=-8.51 and-29.42,P=0.00 and 0.00).The postoperative horizontal and vertical decentration distances of the intraocular lens in the experimental group were(0.24±0.10)mm and(0.25±0.10)mm,respectively,while those in the control group were(0.85±0.77)mm and(2.14±0.50)mm,respectively.The differences between the two groups were statistically signifi-cant(t=-4.82 and-21.68,P=0.00 and 0.00).In the experimental group,neither the horizontal and vertical tilt angles of intraocular lenses nor the horizontal and vertical decentration distances were correlated with postoperative UCVA and BCVA(all P＞0.05).In the control group,the horizontal tilt angle of intraocular lenses was positively correlated with post-operative UCVA and BCVA(both P＜0.05),while the vertical tilt angle was not correlated with postoperative UCVA and BCVA(both P＞0.05);the horizontal decentration distance was positively correlated with postoperative UCVA and BCVA(both P＜0.05),but the vertical decentration distance was not correlated with postoperative UCVA and BCVA(both P＞0.05).Conclusion Both four-point suspension fixation and traditional two-point suspension fixation can effectively im-prove postoperative vision of patients,while the tilt and decentration of the intraocular lens are smaller after four-point sus-pension fixation.

Objective:The study retrospectively analyzed the etiology, clinical manifestations, emergency treatment and etiological treatment of a large sample of cases with hypercalcemic crisis.Methods:The clincial data of patients with hypercalcaemia cirisis who were administered in First Medical Center of Chinese PLA General Hospital from January 2009 to July 2022 were analyzed, inculding the general data, clinical manifestations, etiology, photographic examination, emergency treatment, etiological treatment, serological examination before and after treatment, pathological immunohistochemical findings and prognosis.Results:A total of 143 hypercalcaemia crisis patients(84 males and 59 females) with a mean age of 53.51±16.60 were enrolled. The most common disease was hyperparathyroidism(62/143), followed by solid malignancy(57/143) and multiple myeloma(12/143). Patients presented with digestive system symptoms at 76.91%, followed by neurological symptoms at 63.60%, urinary system symptoms at 58.76%, musculoskeletal symptoms at 55.23%, and cardiovascular system symptoms at 32.91%. After emergency calcium-lowering treatment, the remission rate of hypercalcemic crisis in 143 patients was 100%(143/143), and after etiological treatment, the remission rate of hypercalcemia was 85.31%(122/143).Conclusion:Early identification, emergency treatment and etiology treatment of hypercalcaemia crisis are essential. Effective treament with comprehensive calcium reduction can quickly relieve clinical symptoms and create opportunities for treatment for the cause. Targeted etiological interventions can lead to the correction or long-term remission of hypercalcemia.

The clinical data, laboratory test, and gene mutations were collected from a family with Liddle syndrome. Literatures on Liddle syndrome published in domestic and abroad since 1994 were reviewed and the types of gene mutations were summarized. The proband was diagnosed with hypertension at the age of 24. Laboratory test showed that serum potassium was 3.65 mmol/L, plasma renin was <0.5 mU/L, and plasma aldosterone was 1.5 ng/dL. Proband′s father was diagnosed with hypertension at the age of 34 with the serum potassium 3.34 mmol/L, plasma renin 3.72 mU/L, and plasma aldosterone 6.04 ng/dL. A nonsense mutation(1724G>A, p.Trp575*) in exon 13 of SCNN1G gene was detected in the proband and his father. In 288 cases from 107 families reported in the review of domestic and foreign literature, the incidence of hypertension, hypokalemia, and low renin/low aldosterone were 95.1%, 55.2%, and 49.6%, respectively. This case suggests that the clinical phenotype of Liddle syndrome is heterogeneous. Patients with early-onset hypertension, regardless of whether they are accompanied by hypokalemia, should be screened for renin-angiotensin-aldosterone and genetic testing related to Liddle syndrome should be further detected in patients with low plasma renin/aldosterone.

Objective:Development and validation of a nomogram for predicting the 4-year incidence of type-2 diabetes mellitus (T2DM) in a Chinese population was attempted.Methods:This prospective cohort study was conducted in Shijingshan District Pingguoyuan Community (Beijing, China) from December 2011 to April 2012 among adults aged≥40 years not suffering from T2DM. Finally, 8 058 adults free of T2DM were included with a median duration of follow-up of 4 years. Participants were divided into a modeling group and verification group using simple random sampling at a ratio of 7∶3. Univariate and multivariate Cox proportional risk models were applied to identify the independent risk predictors in the modeling group. A nomogram was constructed to predict the 4-year incidence of T2DM based on the results of multivariate analysis. The Concordance Index and calibration plots were used to evaluate the differentiation and calibration of the nomogram in both groups.Results:A total of 5 641 individuals were in the modeling group and 2 417 people were in the validation group, of which 265 and 106 had T2DM, respectively, at 4-year follow-up. In the modeling group, age ( HR=1.349, 95% CI 1.011-1.800), body mass index ( HR=1.347, 95% CI 1.038-1.746), hyperlipidemia ( HR=1.504, 95% CI 1.133-1.996), fasting blood glucose ( HR=4.189, 95% CI 3.010-5.830), 2-h blood glucose level according to the oral glucose tolerance test ( HR=3.005, 95% CI 2.129-4.241), level of glycosylated hemoglobin ( HR=3.162, 95% CI 2.283-4.380), and level of γ-glutamyl transferase ( HR=1.920, 95% CI 1.385-2.661) were independent risk factors for T2DM. Validation of the nomogram revealed the Concordance Index of the modeling group and validation group to be 0.906 (95% CI 0.888-0.925) and 0.844 (95% CI 0.796-0.892), respectively. Calibration plots showed good calibration in both groups. Conclusion:These data suggest that our nomogram could be a simple and reliable tool for predicting the 4-year risk of developing T2DM in a high-risk Chinese population.
