Recent years have witnessed significant advancements in myopia control research through the application of diffuse optical technology(DOT)spectacle lenses. Myopia has emerged as a global public health challenge, affecting nearly half of the world's population, with childhood and adolescent myopia rates continuing to rise. DOT lenses represent an innovative myopia control intervention based on retinal contrast signal theory. These lenses incorporate micro-light scattering dots distributed across the lens surface to reduce retinal imaging contrast and modulate the influence of visual input on axial elongation, thereby slowing myopia progression. The core mechanism operates through refractive index differences between the lens substrate(1.53)and scattering dots(1.50), which generate optical scattering effects. This design maintains clear vision through a central 5 mm optical zone while effectively reducing contrast signal intensity in the peripheral retina. Large-scale randomized controlled trials, including the CYPRESS study, have demonstrated significant myopia control efficacy in children aged 6-10 years: 12-month follow-up data revealed a 74% reduction in myopia progression and a 50% reduction in axial elongation, with sustained safety and visual quality maintained over 4-year long-term follow-up. However, several aspects of DOT technology remain contentious and require further clinical validation, including its applicability across different age groups, optimal scattering dot density configurations, combined application effects with other myopia control methods, and long-term visual adaptation during extended use. This review systematically examines the theoretical foundations, design characteristics, clinical application progress, and future development directions of DOT technology, providing scientific evidence for clinical myopia prevention and control strategy formulation.

Objective To compare TyG index between the patients with CHF and ADHF to eluci-date the metabolic difference between these two stages.Methods A total of 1156 HF patients ad-mitted in Taizhou People's Hospital between January 2020 and December 2022 were enrolled,and according to 2021 ESC Guidelines for Diagnosis and Treatment of Acute and Chronic Heart Fail-ure,they were divided into CHF group(365 cases)and ADHF group(791 cases).The clinical da-ta,results of laboratory tests,and cardiovascular history were collected,and TyG index was calcu-lated.All-cause death outcome was observed in ADHF patients during a follow-up of 1 year.Results The TyG index was significantly lower in the ADHF group than the CHF group[8.27(7.99,8.62)vs 8.35(8.04,8.75),P=0.001].In the ADHF group,the TyG index was positively correlated with SBP,DBP,TC,TG,LDL-C,FPG,HbA1c,BMI,and LVEF,and negatively with age(P＜0.01).In the CHF group,the index was positively correlated with DBP,TC,TG,LDL-C,FPG,BMI,and HbA1c,and negatively with age(P＜0.05,P＜0.01).Both univariate and multiva-riate logistic regression analyses indicated that the TyG index was a protective factor for ADHF(OR=0.647,95％CI:0.503～0.832,P=0.001;OR=0.694,95％CI:0.536～0.898,P=0.005).Multivariate logistic regression analysis showed that the index in ADHF patients was a protective factor for one-year all-cause mortality(OR=0.483,95％CI:0.254-0.916;P=0.026).Conclusion TyG index might be regarded as an important marker for assessing the metabolic status in HF patients and predicting the prognosis in ADHF patients.

ObjectiveTo analyze the development status and quality of clinical practice guidelines for the treatment of dominant diseases with Chinese patent medicines （CPMs）. MethodsDatabases were searched from Jan. 2019 to Dec.2023 to collect the published clinical practice guidelines of CPMs for the treatment of dominant diseases. The information about the title， the participants， clinical problems， outcomes， evidence grade， recommendations， and recommendation strength in the included clinical practice guidelines were collected， for which the development status was analyzed， and the quality was evaluated with the Scientific， Transparent and Applicable Rankings （STAR） tool for clinical practice guidelines. ResultsTotally， 34 guidelines were included， involving 273 kinds of CPMs. One to ten （with the medium five） clinical problems were proposed from 29 clinical practice guidelines respectively. All the guidelines divided the evidence into four grades according to Grade of Recommendation Assessment， Deve-lopement an Evaluation. And 28 guidelines had five levels of recommendation strength. A total of 344 recommendations were extracted， including 86 strong-recommendations， 191 weak-recommendations （including 36 weak recommendations only based on expert consensus） and 67 recommendations with unclear recommendation strength. All guidelines had high scores in the three areas of “clinical questions （94.20%）”， “evidence （91.45%）” and “recommendations （89.06%）”， while the scores in the three areas of “registry （22.06%）”， “protocol （19.00%）” and “accessibility （31.51%）” were low. The STAR recommended stars of 8 guidelines were 5.0~4.0 stars， while that of 18 guidelines were 3.5~2.5 stars， and 8 guidelines were 2.0~1.0 stars. The three guidelines with the highest recommended stars were depressive disorder， community-acquired pneumonia， and influenza in adult. ConclusionThere is a certain gap in the quality of the published clinical practice guidelines of CPMs， and the quality of the guidelines could be further improved in registry， protocols， funds， and accessibility.

Objective:To illustrate the onset of epileptic seizures in children with brain injury admitted in pediatric intensive care unit (PICU), and to explore the risk factors and the correlation between epileptic seizures and the prognosis.Methods:Clinical data of pediatric patients with brain injury who were admitted to PICU of Peking University First Hospital from January 2013 to December 2019, and monitored by video electroencephalography (VEEG) were retrospectively collected, including general demographic information, etiological data, clinical seizures prior to VEEG performing, in-hospital mortality, brain function score, VEEG manifestations, etc.Seizures detected by VEEG were the primary outcome, and prognosis when discharged from PICU was the secondary outcome. Logistic regression was used to analyze the factors associated with seizures and poor outcome. Results:A total of 284 children were included, involving 54.9%(156/284) males.The median age of included children was 1.7(0.5, 5.0) years.Stratified by the cause of disease, 45.1%(128/284) had epilepsy, 26.1%(74/128) had genetic metabolic disease, and 14.4%(41/284) had central nervous system infection.A total of 82.0%(233/284) children had abnormal VEEG background activities, and 59.5%(169/284) had interictal epileptic discharges.Seizures were detected in 106 cases, including 39.6%(42/106) of non-convulsive seizures and 24.5%(26/106) of non-convulsive epileptic states.There were 12.0% (34/284) had poor prognosis at discharge, including 24 patients died in-hospital, and Pediatric Cerebral Performance Category scores were increased in 10 survivors.Multivariate Logistic regression analysis showed that seizures existed before VEEG monitoring and interictal epileptiform discharge were the independent risk factors for seizure.Besides, mental retardation, sepsis related encephalopathy, consciousness abnormality during VEEG, abnormal VEEG background activity, and epileptic status were significantly correlated with the poor prognosis of children with brain injury in PICU. Conclusions:The incidence of electrographic seizure is higher in children with brain injury in PICU, and VEEG monitoring is beneficial to children with brain injury that achieves an early identification of seizures and prediction of prognosis.

Tumor lysis syndrome is an oncologic emergency that seriously threatens the lives of pa-tients. Prevention of tumor lysis syndrome is more important than treatment. According to the risk classifica-tion,identifying high risk patients and effective preventive measures can improve the prognosis of patients. Patients with tumor lysis syndrome should receive hydration, rasburicase, diuretics, correction of electrolyte imbalances and appropriate renal replacement therapy.

Objective The study the clinical characteristics and death risk factors in patients infected with severe fever with thrombocytopenia syndrome bunyavirus (SFTSV). Methods The clinical data of 56 patients infected with SFTSV from May 2011 to October 2016 were retrospectively analyzed. The clinical characteristics and laboratory examination results were compared between cured patients and death patients. The death risk factors were analyzed by two classification Logistic regression analysis. Results Among the 56 cases, 40 cases were cured and 16 cases were dead, and the time of onset to death was (12 ± 3) d. All patients showed symptoms including fever and weakness. Bone marrow biopsy was performed in 26 cases, and hemophagocytic phenomenon was found in 21 cases. Compared with cured patients, the death patients were older; the rate of underlying diseases was higher; fever time was longer; the incidences of skin and/ or gastrointestinal bleeding, neuropsychiatric symptoms, abnormal troponin and arrhythmias were higher, platelet, CD4+and CD8+were lower; the levels of activated partial thromboplastin time (APTT), creatine kinase (CK), lactate dehydrogenase (LDH), viral load, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were higher, and there were statistical differences (P＜0.01 or ＜0.05). Two classification Logistic regression analysis result showed that viral load ≥ 5 lgTCID50/ml, age ≥ 70 years, platelet ＜ 20 × 109/L, CK ＞ 1 200 U/L, fever time ＞ 8 d, APTT ≥ 120 s, troponin elevation and neuropsychiatric symptoms were the independent risk factors of death in patients infected with SFTSV (P＜0.01 or＜0.05). Conclusions The high viral load, high age, lower platelet, increased CK, prolonged fever time and APTT, elevated troponin and neuropsychiatric symptoms were independent risk factors of death in patients infected with SFTSV. Early identification for the risk factors of death may improve the prognosis.
