Phacoemulsification represents the mainstream, efficient, and safe surgical modality for cataract treatment, and continuous technological advances have further improved the safety profile of this procedure in ordinary patients. However, patients with high myopia feature inherent anatomical abnormalities of the eyeball, leading to a fundamental incompatibility with conventional phacoemulsification protocols. Such patients face a markedly elevated risk of both anterior and posterior segment perioperative complications, posing a persistent clinical challenge in cataract surgery. Focusing on the unique ocular anatomical characteristics associated with high myopia, this review systematically summarizes the distinct traumatic effects and pathological impacts of phacoemulsification on the anterior and posterior ocular segments of affected patients. Moving beyond generalized discussions of routine cataract management, it consolidates clinical evidence specific to this special-population patients, aiming to provide refined references for perioperative risk prevention and control in cataract patients complicated with high myopia.

OBJECTIVE: The objective of our study was to evaluate the vaccine effectiveness (VE) of the pentavalent rotavirus vaccine (RV5) among < 5-year-old children in three provinces of China during 2020-2024 via a propensity score-matched test-negative case-control study. METHODS: Electronic health records and immunization information systems were used to obtain data on acute gastroenteritis (AGE) cases tested for rotavirus (RV) infection. RV-positive cases were propensity score matched with RV-negative controls for age, visit month, and province. RESULTS: The study included 27,472 children with AGE aged 8 weeks to 4 years at the time of AGE diagnosis; 7.98% (2,192) were RV-positive. The VE (95% confidence interval, CI) of 1-2 and 3 doses of RV5 against any medically attended RV infection (inpatient or outpatient) was 57.6% (39.8%, 70.2%) and 67.2% (60.3%, 72.9%), respectively. Among children who received the 3rd dose before turning 5 months of age, 3-dose VE decreased from 70.4% (53.9%, 81.1%) (< 5 months since the 3rd dose) to 63.0% (49.1%, 73.0%) (≥ 1 year since the 3rd dose). The three-dose VE rate was 69.4% (41.3%, 84.0%) for RVGE hospitalization and 57.5% (38.9%, 70.5%) for outpatient-only medically attended RVGE. CONCLUSION Three-dose RV5 VE against rotavirus gastroenteritis (RVGE) in children aged < 5 years was higher than 1-2-dose VE. Three-dose VE decreased with time since the 3rd dose in children who received the 3rd dose before turning five months of age, but remained above 60% for at least one year. VE was higher for RVGE hospitalizations than for medically attended outpatient visits.

This study aims to analyze the screening results and epidemiological characteristics of prostate cancer (PCa) among elderly males in the rural areas of Songjiang, Shanghai City, through the implementation of a preliminary prostate-specific antigen (PSA) screening based on a community-linkage model, and to explore an effective screening approach. A retrospective observational study design was employed to collect data from residents who underwent PSA screening at Songjiang Hospital affiliated to Shanghai Jiao Tong University School of Medicine, in collaboration with multiple community health service centers in Songjiang District, Shanghai City, between June 2022 and June 2024, through free clinics and annual health examinations. Prostate biopsy was recommended for individuals with total PSA (tPSA) levels >10 ng/ml and those with 4 ng/ml≤tPSA≤10 ng/ml and abnormal free-to-total PSA (f/tPSA) ratios. Clinical characteristics of detected PCa patients were analyzed. Follow-up was conducted through phone calls and home visits by family doctors, coupled with enhanced health education. The results indicated that a total of 17 198 residents participated in the screening, among which 2 234 (12.99%) had tPSA levels between 4 ng/ml and 10 ng/ml, and 257 (1.49%) had tPSA levels >10 ng/ml. Ultimately, 417 residents underwent prostate biopsy, with 171 being diagnosed with PCa, yielding a positive biopsy rate of 41.00% and a PCa detection rate of 0.99%. The predominant pathological subtype among PCa patients was adenocarcinoma (168 cases, 98.24%). Of the 146 PCa patients who received treatment, the majority were classified as intermediate or high-risk (124 cases, 84.93%). Furthermore, with the optimization of the screening model, there was a significant increase in the proportion of subsequent outpatient visits. In conclusion, the community-linkage-based PSA screening model demonstrated high effectiveness in screening for PCa among elderly males in the rural areas of Songjiang, Shanghai City. Epidemiological findings revealed that PCa patients in this region are primarily composed of intermediate and high-risk groups, highlighting the need for intensified early screening and health education.

Objective:To explore the effect on cardiac remodeling of combining high-intensity interval training with metformin in cases of type 1 diabetes mellitus (T1DM) and its possible mechanisms.Methods:Sixty male Sprague-Dawley rats were randomly divided into control, model, exercise, drug and combination groups with twelve per group. T1DM was induced in all except the control group using a single intraperitoneal injection of streptozotocin (60mg/kg of body weight). The control and model groups were then housed without intervention, while the drug and exercise groups underwent metformin gavage (300mg/kg/day) or 8 weeks of high-intensity interval training (3 sessions/week), respectively. The combination group receiving both. After the training, body weight, a cardiac index (heart weight/body weight), and fasting blood glucose (FBG) were measured in all of the rats. Echocardiography assessed cardiac structure and function, and myocardial tissue was collected for HE or Masson staining to measure cardiomyocyte width and collagen volume fraction respectively. Protein expression and the levels of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), transforming growth factor-β (TGF-β), collagen (Col), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), phosphorylated AMP-activated protein kinase (p-AMPK), ryanodine receptor (RyR), and sarcoplasmic reticulum calcium ATPase (SERCA) were determined using western blotting.Results:Compared with the control group, the model group showed significantly increased cardiac indices, FBG levels, and left ventricular end-systolic and end-diastolic diameters. But they had significantly decreased body weight, left ventricular fractional shortening and ejection fraction. Compared with the control group, there was a significant increase in the cardiomyocyte width and collagen volume fraction, as well as in ANP, BNP, TGF-β, and Col levels in the model group, along with downregulated PGC-1α, p-AMPK, RyR, and SERCA protein expression. Compared with the model group, the exercise, drug, and combination groups exhibited varying degrees of improvement in all these indicators, with the most pronounced effects in the combination group.Conclusions:High-intensity interval training combined with metformin promotes cardiac remodeling in T1DM rats, outperforming either intervention alone. The mechanism may involve minimizing myocardial fibrosis and pathological hypertrophy, restoring mitochondrial function and intracellular calcium homeostasis.

Objectives:To explore the feasibility of zero-ray radiofrequency catheter ablation for paroxymal atrial fibrillation under the guidance of transthoracic echocardiography combined with three-dimensional mapping system.Methods:This is a single-center prospective observational study.A total of 12 patients with paroxysmal atrial fibrillation who underwent radiofrequency catheter ablation in Fuwai Hospital,Chinese Academy of Medical Sciences from June 1,2024 to September 30,2024 were included.All patients underwent successful percutaneous puncture,atrial septal puncture under the guidance of transthoracic echocardiography,and all patients underwent left atrial modeling and discharge ablation under the guidance of transthoracic echocardiography combined with three-dimensional mapping system.The disappearance of pulmonary vein potential was confirmed after the ablation operation and as the ablation endpoint and successful ablation marker.The operation results and 1-month and 3-month follow-up results of the patients were observed.Results:There were 12 patients with paroxysmal atrial fibrillation,9 males and 3 females,aged(56.8±11.2)years,with a history of paroxysmal atrial fibrillation(4.2±2.3)years.The mean left atrial diameter was(36.5±2.5)mm,the left ventricular end-diastolic diameter was(47.8±4.1)mm,and the left ventricular ejection fraction was 55%-65%.The mean overall operation time was(102.25±14.51)min,the ultrasound operation time was(29.58±6.23)min,and the catheter operation time was(33.08±4.10)min.All patients completed circumferential pulmonary vein isolation without intraoperative complications.The hospitalization time was 2-6 days.At the 1-month follow-up after ablation,all patients showed sinus rhythm on 24-hour ambulatory electrocardiogram,and 2 patients had occasional atrial premature contractions without recurrence of atrial fibrillation.At the 3-month follow-up,two patients had occasional premature atrial contractions,and no recurrence of atrial fibrillation was recorded on the electrocardiogram of all patients.Conclusions:It is feasible to complete radiofrequency catheter ablation of paroxysmal atrial fibrillation under the guidance of transthoracic echocardiography combined with three-dimensional mapping system.

Objective To explore the relationship between triglyceride-glucose(TyG)index and hypertension in patients with cerebral hemorrhage.Methods A total of 1718 patients with cere-bral hemorrhage admitted to our hospital from January,2013 to May,2023 were enrolled in this study.According to the TyG index quartile,437 cases were assigned into Q1 group(≤8.375),424 cases into Q2 group(TyG index 8.376～8.737),429 cases into Q3 group(TyG index 8.738～9.087),and 428 cases into Q4 group(≥9.088).The general clinical data were compared in the four groups.Logistic regression analysis was used to study the correlation between TyG index and hy-pertension.Results There were significant differences among the four groups in terms of age,hy-pertension,diabetes,SBP,DBP,TC,TG,HDL-C,LDL-C,FBG,glycated hemoglobin and TyG in-dex(P＜0.05,P＜0.01).Logistic regression analysis showed that when the TyG index was a con-tinuous variable,it was significantly correlated with the risk of hypertension(OR=1.999,95％CI:1.393-2.869,P=0.001).When the index was used as a categorical variable,with Q1as a ref-erence,TyG index in Q3 and Q4 was associated with an increase in OR of hypertension(OR=1.869,95％CI:1.220-2.865,P=0.004;OR=1.844,95％CI:1.125-3.020,P=0.015).After ad-justing cofounders,the association of TyG index and risk of hypertension was stronger in the fe-males(OR=2.618,95％CI:1.312-5.221,P=0.006)than the males(OR=1.783,95％CI:1.151-2.761,P=0.010),and in the patients ≥65 years old(OR=3.277,95％CI:1.600-6.741,P=0.001)than those＜65 years old(OR=1.782,95％CI:1.076-2.949,P=0.025).Conclusion TyG index is closely associated with hypertension in patients with cerebral hemorrhage,especially in women and elderly.

Objective:To establish 30-day of age transcutaneous bilirubin (TcB) reference curves for healthy neonates, and to investigate regional variations in bilirubin dynamics.Methods:A multicenter retrospective cohort study was conducted. A total of 220 950 healthy neonates born at a gestational age of 35-<42 weeks, with a birth weight ≥2 000 g, who did not receive phototherapy within 60 h after birth were recruited. All of them underwent remote TcB monitoring using the Bilibaby remote jaundice monitoring system between August 1 st, 2020 and December 31 st, 2024 in 426 hospitals. TcB data were collected within the period from birth to 30-day of age. The P40, P75, and P95 of TcB values were calculated, and dynamic TcB curves for 30-day of age were constructed. Patterns of bilirubin change, rates of change, and transition outcomes were described. Regional comparisons between South and North were conducted using linear mixed-effects models for TcB trajectories and Pearson′s chi-square test for outcome differences. Results:A total of 220 950 neonates were included, of whom 101 711 (46.03%) were female. Gestational age at birth was (38.75±1.12) weeks, and birth weight was (3 272±417) g. TcB levels increased rapidly within 3-day of age, peaked at 4-6-day of age, with peak values at P40, P75, and P95 of 200.6, 239.7 and 275.4 μmol/L (11.8, 14.1 and 16.2 mg/dl), respectively. TcB levels gradually declined thereafter and stabilized after 13-day of age, with values at P40, P75, and P95 fluctuating between 147.9-159.8, 190.4-200.6, and 231.2-239.7 μmol/L (8.7-9.4, 11.2-11.8, 13.6-14.1 mg/dl), respectively. Notably, among neonates categorized as low-or low-intermediate-risk within 3-day of age, 6 700 (12.76%) progressed to intermediate-high or high risk between 4 and 30 days of age. Before 13-day of age, TcB levels in the southern regions were consistently higher than those in the northern regions ( P=0.039); from 14 to 30 days of age, the overall TcB levels had no statistically difference, but the temporal changes in TcB still showed regional differences (degrees of freedom=3, all interaction P<0.05). Among neonates classified as low-or low-intermediate risk within 3-day of age, 25 326 were from southern regions, of whom 4 254 (16.80%) progressed to intermediate-high or high risk between 4 and 30 days of age. In northern regions, 27 193 neonates were classified as low-or low-intermediate risk within 3-day of age, among whom 2 446 (8.99%) progressed to intermediate-high or high risk. The risk progression between the 2 regions had statistically difference ( χ2=716.49, P<0.001). Conclusions:A TcB percentile curve for neonates within 30-day of age was established, revealing that both the overall TcB level and its temporal trend were higher in southern than in northern newborns. These findings provide baseline data to support continuous management of neonatal jaundice.
