AIM: To compare the clinical outcomes of extended depth-of-focus intraocular lenses(EDOF IOLs)using either micromonovision implantation or mixed implantation of EDOF and diffractive bifocal IOLs.METHODS: This retrospective clinical trial included 130 patients(260 eyes), who were divided into two groups. Group RR comprised 70 patients(140 eyes)bilaterally implanted with ZXR00 IOLs(Tecnis ZXR00, where one target was -0.5 D to -0.75 D and the other was 0 to -0.25 D). Group RM comprised 60 patients(120 eyes)unilaterally implanted with both ZXR00 and ZMB00 IOLs(Tecnis ZMB00, 0 to -0.25 D). Postoperative outcomes were compared after 3 mo, including visual acuity, defocus curves, stereoacuity, modulation transfer functions(MTFs), higher-order aberrations, and Visual Function-14(VF-14)questionnaire responses.RESULTS: Group RR had superior bilateral intermediate vision, while the group RM had superior bilateral near vision(both P<0.05). Group RM also exhibited superior MTFs and reduced higher-order aberrations(both P<0.05). Stereoacuity and VF-14 questionnaire results showed no statistically significant difference between groups(P>0.05).CONCLUSION: The implantation of micromonovision has significantly improved near vision. IOLs and their collocation can be customized according to individual patient needs to achieve precise treatment and provide cataract patients with high-quality vision.

Intraocular ointment is conventionally placed on the eye to prevent infection after cataract surgery. The purpose of this study is to report a case and conduct a systematic review of a rare occurrence of the entry of intraocular ointment after cataract surgery. PubMed, Scopus, Embase, CNKI, WANFANG data, China Science and Technology Journal Database and Chinese Medical Journal Full-text Database were systematically searched from their commencement to 30th October 2023, and 19 literatures were screened out and 31 cases of intraocular ointment after surgery were collected. Among the 31 patients, the age of presentation ranged from 55 to 87 years with a median of 73, males accounted for 45.2% and females accounted for 32.3%. The length of the incision was generally 3.2 mm. Most of the patients detected ointment within 3 days post-operation and presented without complications(45.2%). The most common ocular manifestations were corneal edema, glaucoma and uveitis. Early postoperative follow-up is very important. Presence of anterior chamber ointment is a rare complication after cataract surgery, but it can lead to severe vision loss if not detected and treated on time. When patients complain of foreign body sensation in the in the eye after cataract surgery, ophthalmologists need to take a kin interest and examine the eye for early detection of ointment for appropriate intervention and prevent further complications.

Objective: To explore the association between dietary patterns and overweight and obesity among primary and middle school students, so as to provide the guidance of diet balance and obesity prevention for students. Methods: Students from 11 primary and middle schools in Tongzhou District, Beijing Municipality, were selected using the stratified cluster sampling method. Demographic information was collected through a general questionnaire, and dietary intake types and frequencies over the past week were assessed using a food frequency questionnaire. Dietary patterns were determined using factor analysis, and the dietary pattern factor scores were divided into Q1, Q2, Q3, and Q4 groups based on quartiles. Height and weight were collected through physical examinations, and Z-scores of body mass index adjusted for gender and age were calculated to assess overweight and obesity. The association between dietary patterns and overweight and obesity was analyzed using a multivariable logistic regression model. Results: A total of 1 485 students were surveyed, including 745 males (50.17%) and 740 females (49.83%). The mean age was (12.87±2.86) years. Three dietary patterns were identified: animal and plant protein dietary pattern, high-fat and high-sugar dietary pattern, and vegetable-fruit-dairy dietary pattern. The detection rates of overweight and obesity were 42.57%, 48.42%, and 34.75%, respectively, with statistically significant differences (P<0.05). Multivariable logistic regression analysis showed that compared with the vegetable-fruit-dairy dietary pattern, the animal and plant protein dietary pattern (OR=1.406, 95%CI: 1.084-1.823) and the high-fat and high-sugar dietary pattern (OR=2.137, 95%CI: 1.643-2.779) were associated with a higher risk of overweight and obesity among primary and middle school students. Compared with the Q1 group of dietary pattern factor scores, the Q3 group (OR=1.631, 95%CI: 1.206-2.208) and Q4 group (OR=1.965, 95%CI: 1.446-2.671) of the high-fat and high-sugar dietary pattern had an increased risk of overweight and obesity, while the Q4 group of the vegetable-fruit-dairy dietary pattern (OR=0.551, 95%CI: 0.406-0.747) had a reduced risk of overweight and obesity. There was no statistical association between factor scores of animal and plant protein dietary pattern and overweight and obesity (all P>0.05). Conclusions The animal and plant protein dietary pattern and the high-fat and high-sugar dietary pattern are associated with a higher risk of overweight and obesity among primary and middle school students. Within the same dietary pattern, the more inclined students are to the high-fat and high-sugar dietary pattern, the higher their risk of overweight and obesity, while the more inclined they are to the vegetable-fruit-dairy dietary pattern, the lower their risk of overweight and obesity.

OBJECTIVE To investigate the effects of triptolide （TP） exposure during pregnancy and lactation on the reproductive system development and function in male offspring of rats， providing a reference for medication safety during pregnancy and lactation. METHODS Pregnant rats were randomly divided into control group （12 rats， normal saline） and T1-T4 groups [12， 13， 14， 17 rats that received TP at 200， 400， 600， and 800 μg/（kg·d） respectively]. They were given relevant medicine/normal saline intragastrically， once a day， until the offspring were born and naturally weaned， the intragastric administration volume of each rat was consistently 2 mL. After 60 days of feeding， reproductive organ weights and coefficients were measured in male offspring， testicular and epididymal histology and sperm morphology were observed. Sperm motility， sperm count， and serum levels of gonadotropin-releasing hormone （GnRH）， follicle stimulating hormone （FSH）， luteinizing hormone （LH）， and testosterone （T） in the epididymides were analyzed. Protein expressions of glycogen synthase kinase 3α （GSK3α）， phosphorylated GSK3α （p-GSK3α）， and phosphatase 1γ2 （PP1γ2） in sperm were also determined. RESULTS Compared with the control group， the testicular and epididymal weights， serum levels of GnRH and T， the relative protein expression of PP1γ2 were significantly decreased in T1-T4 groups. Additionally， in the T2 to T4 groups， there were significant reductions in the weight and coefficient of the seminal vesicle， total number of sperm， sperm concentration， sperm motility as well as relative protein expressions of GSKα， p-GSK3α in the offspring rats. Furthermore， the epididymal coefficient in the T3 and T4 groups， the testicular coefficient， mean sperm track velocity and sperm curvature velocity in the T4 group were significantly decreased （P＜ 0.05）； the number of abnormal sperm， rate of sperm abnormality， and levels of FSH and LH in the offspring rats of the T1 to T4 groups were all significantly increased （P＜0.05）； in the offspring rats of the T1 to T4 groups， there was a decrease in the number of epithelial cells in the seminiferous tubules of the testes. Within the epididymal tissue， degenerative and necrotic changes in the epithelial cells were visible， accompanied by mild infiltration of inflammatory cells in the stroma. CONCLUSIONS TP exposure during pregnancy and lactation disrupts reproductive organ development， impairs spermatogenesis and sperm motility， as well as suppresses androgen synthesis in male offspring，thereby having a negative impact on the development of the reproductive system. These effects may be mechanistically linked to regulation of GSK3α， p-GSK3α and PP1γ2 protein expressions.

OBJECTIVE To investigate the effects and mechanism of Wenpi tongluo kaiqiao formula （WPTL） against neuronal necroptosis in Alzheimer’s disease （AD） mice based on the Z-DNA binding protein 1 （ZBP1）/mixed lineage kinase domain-like protein （MLKL） signaling pathway. METHODS Forty APP/PS1 transgenic AD mice were randomly divided into model group， WPTL low-dose （WPTL-L） group （10.4 g/kg， calculated by the raw medicine）， WPTL high-dose （WPTL-H） group （20.8 g/kg， calculated by the raw medicine） and donepezil hydrochloride group （3 mg/kg）， with 10 mice in each group； another 10 C57BL/6J mice were selected as normal control group. Intragastric administration， once a day， for 30 consecutive days. Twenty-four hours after the last administration， Morris water maze test was performed to evaluate learning and memory abilities； the pathological morphology of hippocampal tissues was observed； the serum levels of tumor necrosis factor-α （TNF-α） and interleukin-4 （IL-4） were determined； the expressions of amyloid precursor protein （APP）， Tau protein， and ZBP1/MLKL signaling pathway-related proteins in hippocampal tissues were detected； the positive expression of phosphorylated receptor-interacting protein kinase 3 （p-RIPK3） in the neurons of hippocampal tissues and mRNA expression of ZBP1 were measured in hippocampal tissues. RESULTS Compared with normal control group， the escape latency of mice in model group was prolonged significantly on day 3 to 5 （P＜0.05）， the times of crossing platform reduced significantly （P＜0.05）， and obvious pathological changes were observed in the hippocampal tissue. The level of TNF- α， the expressions of APP， p-Tau and ZBP1， the phosphorylation levels of RIPK1， RIPK3 and MLKL， the fluorescence intensity of p-RIPK3 as well as the mRNA expression of ZBP1 were significantly increased （P＜0.05）， while the serum level of IL-4 was decreased significantly （P＜0.05）. Compared with model group， above indexes were reversed significantly in administration groups （P＜0.05）， and pathological damage of hippocampal tissue was alleviated. CONCLUSIONS WPTL can inhibit the ZBP1/MLKL signaling pathway， reduce neuronal necroptosis in AD mice， and inhibit inflammatory responses， thereby improving learning and spatial memory abilities in AD mice.

OBJECTIVE To investigate the efficacy and safety of tirofiban for early neurological deterioration in patients with acute ischemic stroke. METHODS A total of 126 patients with early neurological deterioration of acute ischemic stroke who were admitted to the Department of Neurology， Heji Hospital Affiliated to Changzhi Medical College from January 2022 to December 2023 were selected and divided into observation group and control group according to random number table method， with 63 cases in each group. All patients received standardized treatment such as lipid-lowering and blood pressure-lowering therapy. Based on the standard treatment， patients in the control group additionally took Aspirin enteric-coated tablets 100 mg+Clopidogrel bisulfate tablets 75 mg orally （once a day， for 14 consecutive days）. The patients in the observation group received Tirofiban hydrochloride and sodium chloride injection based on the standardized treatment [first intravenous infusion of 0.40 μg/（kg·min） for 30 min， and then continuous intravenous infusion of 0.10 μg/（kg·min） for 47.5 h]； subsequently， patients were given Aspirin enteric-coated tablets （100 mg） and Clopidogrel bisulfate tablets （75 mg） once a day for 14 consecutive days. The clinical efficacy， the National Institutes of Health Stroke Scale （NIHSS） score， modified Rankin Scale （mRS） score， and hemorheological indexes before and after treatment were compared between the two groups， and the adverse reactions were recorded. RESULTS The total effective rate （87.30%） of the observation group was significantly higher than that of the control group （71.43%） （P＜0.05）. NIHSS scores of the two groups at 1st， 7th and 14th day after treatment， the mRS score at 90th day after treatment， and the platelet aggregation rate， whole blood viscosity， plasma viscosity and fibrinogen at 14th day after treatment were significantly lower than those before treatment in the same group， and the observation group was significantly lower than the control group at the same period （P＜0.05）. The total incidences of adverse reactions such as nausea， headache， fever， gastrointestinal bleeding， oral and nasal mucosal bleeding and thrombocytopenia in both groups of patients were 28.57% respectively， with no statistically significant difference （P＞0.05）. CONCLUSIONS For patients with early neurological deterioration in acute ischemic stroke， the addition of tirofiban can accelerate the recovery of neurological function， improve blood hyperviscosity and platelet aggregation， and improve the prognosis of patients with good safety.

Background and Objectives: The Fractional Flow Reserve and Intravascular UltrasoundGuided Intervention Strategy for Clinical Outcomes in Patients with Intermediate Stenosis (FLAVOUR) trial demonstrated non-inferiority of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared with intravascular ultrasound (IVUS)-guided PCI. We sought to investigate the cost-effectiveness of FFR-guided PCI compared to IVUS-guided PCI in Korea. Methods: A 2-part cost-effectiveness model, composed of a short-term decision tree model and a long-term Markov model, was developed for patients who underwent PCI to treat intermediate stenosis (40% to 70% stenosis by visual estimation on coronary angiography).The lifetime healthcare costs and quality-adjusted life-years (QALYs) were estimated from the healthcare system perspective. Transition probabilities were mainly referred from the FLAVOUR trial, and healthcare costs were mainly obtained through analysis of Korean National Health Insurance claims data. Health utilities were mainly obtained from the Seattle Angina Questionnaire responses of FLAVOUR trial participants mapped to EQ-5D. Results: From the Korean healthcare system perspective, the base-case analysis showed that FFR-guided PCI was 2,451 U.S. dollar lower in lifetime healthcare costs and 0.178 higher in QALYs compared to IVUS-guided PCI. FFR-guided PCI remained more likely to be cost-effective over a wide range of willingness-to-pay thresholds in the probabilistic sensitivity analysis. Conclusions Based on the results from the FLAVOUR trial, FFR-guided PCI is projected to decrease lifetime healthcare costs and increase QALYs compared with IVUS-guided PCI in intermediate coronary lesion, and it is a dominant strategy in Korea.

Background/Aims: The World Health Organization set the goal of eliminating hepatitis C virus (HCV) by 2030, with 80% and 65% reductions in HCV incidence and mortality rates, respectively. We aimed to evaluate the health benefits, cost-effectiveness and return on investment (ROI) of HCV elimination. Methods: Using an HCV transmission compartmental model, we evaluated the benefits and costs of different strategies combining screening and treatment for Chinese populations. We identified strategies to achieve HCV elimination and calculated the incremental cost-effectiveness ratios (ICERs) per disability-adjusted life year (DALY) averted for 2022–2030 to identify the optimal elimination strategy. Furthermore, we estimated the ROI by 2050 by comparing the required investment with the economic productivity gains from reduced HCV incidence and deaths. Results: The strategy that results in the most significant health benefits involves conducting annual primary screening at a rate of 14%, re-screening people who inject drugs annually and the general population every five years, and treating 95% of those diagnosed (P14-R4-T95), preventing approximately 5.75 and 0.44 million HCV infections and deaths, respectively, during 2022–2030. At a willingness-to-pay threshold of $12,615, the P14-R4-T95 strategy is the most cost-effective, with an ICER of $5,449/DALY. By 2050, this strategy would have a net benefit of $120,997 million (ROI=0.868). Conclusions Achieving HCV elimination in China by 2030 will require significant investment in large-scale universal screening and treatment, but it will yield substantial health and economic benefits and is cost-effective.
