Congenital entropion, an abnormal condition in which the eyelids roll inward, with the eyelashes losing their normal angulation and tilting toward the eye, especially in the lower eyelids and inner canthus, often occurs in infants and young children. Congenital entropion may lead to corneal epithelial abrasion, inflammation and ulcer, which may affect the function of the eye if not treated in time. Early surgical intervention is helpful to the health of children's eyes. The purpose of surgery is to change the structure of eyelid and weaken the force of entropion, thus improving the symptoms and corneal astigmatism. At present, there are many surgical treatments for congenital entropion. In this paper, the advantages, disadvantages and indications of these treatments are analyzed and summarized, providing a reference for clinical practice.

In many neurodegenerative diseases,eye movement is disrupted,which is a common and early characteris-tic of neurodegenerative diseases.Characterizing eye movement is important for the diagnosis of neurodegenerative disea-ses,helping to track disease progression and response to treatment.In recent years,eye tracking technology has been ap-plied to the assessment of cognitive function in patients with neurodegenerative diseases.Compared to traditional cognitive assessment methods,the technology has higher temporal and spatial resolution for sensitive quantification.Eye tracking da-ta confirms that executive dysfunction is common in Parkinson's disease and amyotrophic lateral sclerosis,while attention deficit is a characteristic of Alzheimer's disease and multiple sclerosis.Research using eye tracking to evaluate the cogni-tive function of epilepsy patients is still in its early stages,but this method has shown advantages.In this article,the appli-cation of eye tracking technology in neurodegenerative diseases is reviewed.

Objective:To investigate the changes of blood glucose and blood lipid in gestational diabetes mellitus (GDM) patients with different insulin sensitivity during pregnancy and the effect of non-drug intervention.Methods:Data of 240 pregnant women with GDM and 240 healthy pregnant women were collected from July 1 to September 1, 2023 in Shijing People′s Hospital in Baiyun District and other five hospital. The insulin sensitivity index (ISI) was calculated by homeostasis model assessment 2(HOMA2) model, according to the 25th percentile of ISI of normal pregnant women, GDM patients were divided into insulin sensitive group (group A) and insulin sensitive deficiency group (group B), and group A and group B were divided into two groups according to 36-week blood glucose control: group A1 with good blood glucose control (group A1 and group B1) and group A2 with bad blood glucose control (group A2 and group B2). The age, body mass index (BMI) before pregnancy, fasting plasma glucose (FPG), blood lipids and blood glycated hemoglobin (HbA 1c ) in the first trimester, blood glucose and blood lipids in the second trimester were compared at the 28th, 32nd and 36th weeks of gestation, the number of cases, blood glucose, blood lipids and non-drug intervention were measured. Results:There were 166 cases in group A and 74 cases in group B. Blood glucose and blood lipid were normal in early pregnancy. There was no significant difference in blood glucose between group A and group B during the second trimester. The levels of blood lipids were significantly higher than those during the first trimester, and the levels of triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) were significantly higher than those during the first trimester. The number of pregnant women in group A1 was significantly more than that in group A2 in the third trimester ( P = 0.01), and the number of pregnant women in group B1 was more than that in group B2 at 28 weeks ( P = 0.01). At 32 weeks, the number of pregnant women in group B1 and group B2 was similar ( P = 0.31). At 36 weeks, the number of pregnant women in group B1 was significantly lower than that in group B2 ( P = 0.01). In the third trimester of pregnancy, the levels of blood glucose in group B2 were higher than those in group A2 ( P<0.05). The levels of TG and LDL-C in group A2 and group B2 were higher than those in group A1 and group B1 respectively, high-density lipoprotein cholesterol (HDL-C) was lower than that in group A1 and group B1( P<0.05), and there was no significant difference in TC between group A2 and group A1 at 28 and 32 weeks ( P>0.05), but it was significantly higher at 36 weeks ( P = 0.01). In the third trimester of pregnancy, diet control was the most common (91.7%, 87.7%, 81.6%, respectively) in group A ( P>0.05). The proportions of diet-only and diet-plus exercise interventions were similar in group B1 at 28 weeks and 32 weeks (52.9% vs. 47.1%, 45.7% vs. 54.3%)( P = 0.072, 0.113). At the 36 weeks, the main intervention was diet combined with exercise (73.3%). In group B2, dietary intervention (69.6%, 71.8%, 69.5%) was the main cause of poor control of blood glucose. Conclusions:In GDM patients with insulin sensitivity deficiency, the blood glucose and blood lipids in the second trimester are obviously increased, and the abnormality in the third trimester is even greater.

N6-methyladenosine(m6A)is produced by methylation of the 6th nitrogen atom of ade-nine.The m6A methylation modification is the most common internal modification of RNA,and the modifica-tion process mainly relies on m6A-related enzymes,including methyltransferases,demethylases and binding proteins.The core structure of the methyltransferase complex(MTC)is methyltransferase-like 3(METTL3).The pathogenesis of osteoarthritis(OA)is intricate and complex,and various factors interact with each other.This paper summarizes the mechanism of action of m6A and related enzymes,and elaborates the pathogenesis of os-teoarthritis from the aspects of chondrocytes,proteases,cytokines and signaling pathways,emphatically intro-duces the regulatory role of METTL3 on OA in m6A methylated modification.The aim is to provide new per-spectives on the pathogenesis of osteoarthritis in order to provide new ideas and approaches for the treatment of osteoarthritis.

Background and purpose:Human epidermal growth factor receptor 2(HER2)is closely associated with drug efficacy and prognosis in urothelial carcinoma(UC).HER2 is a significant biomarker and therapeutic target in various tumors.In recent years,anti-HER2 antibody-drug conjugates have shown significant clinical efficacy in UC patients with HER2 overexpression.Therefore,an in-depth understanding of HER2 expression and its characteristics in Chinese UC patients is crucial to guide treatment decision-making,optimize treatment strategies and achieve personalized therapy.This study aimed to thoroughly investigate correlation of HER2 expression and clinicopathological characteristics in Chinese patients with UC.Methods:This study was a multicenter study that retrospectively included UC patients from urology departments of 8 tertiary hospitals in 5 geographical regions of China(North China,East China,South China,Central China and Northwest)whose tissue samples were collected from January 2023 to March 2024.Inclusion criteria:① age above 18 years;② UC diagnosed by histopathological or cytological examination;③ complete results of HER2 expression detection using immunohistochemistry(IHC)in the primary tumor site were required.Exclusion criteria:① diagnosed patients with tumors in other parts of the body;② physicians evaluated other situations that were not suitable for inclusion in this study.IHC results for HER2 expression and clinicopathological data were collected.HER2 expression was determined according to the criteria outlined in"Clinical pathological expert consensus on HER2 testing in urothelial carcinoma in China",with HER2 2+and 3+defined as HER2 overexpression.The HER2 expression and clinicopathological features were analyzed.This study was approved by the medical ethics committee of Fudan University Shanghai Cancer Center(ethical number:2301268-12)and was registered at China Clinical Trial Registry(registration number:ChiCTR2300069746).Results:A total of 1054 patients with UC were included.Most of the tumors were bladder UC(n=807,76.6%).The mean age of patients was(66.8±10.5)years,and the majority were male(78.5%).The HER2 overexpression rate was 58.4%(n=616),with an additional 23%of patients having HER2 1+expression(n=242),and a small proportion exhibiting negative HER2 expression(n=196,18.6%).HER2 expression was significantly associated with various clinical and pathological characteristics such as Eastern Cooperative Oncology Group(ECOG)performance status,history of cardiovascular disease,history of metabolic disorders,smoking,UC disease location,differentiation grade,pathological type,and tumor stage.Conclusion:Retrospective analysis of multi-center data shows that HER2 expression is frequently observed in Chinese UC patients,with an overexpression rate of up to 58.4%.Furthermore,HER2 expression is closely associated with various clinical and pathological features of UC patients.This study underscores the critical importance of accurately assessing HER2 expression in UC patient to guide personalized therapies.

Objective:To explore the effect of "Internet +" combined with multidisciplinary out of hospital management in hospital-home transitional period management of patients after lumbar internal fixation.Methods:From October 2021 to September 2022, convenience sampling was used to select 176 patients who underwent lumbar internal fixation at the Department of Orthopedics of the First Affiliated Hospital of Zhengzhou University. According to the admission time, patients enrolled from October 2021 to March 2022 were included in the control group, and patients enrolled from April to September 2022 were included in the observation group, with 88 cases in each group. The control group implemented routine out of hospital follow-up management, while the observation group implemented "Internet +" combined with multidisciplinary out of hospital management. After three months of intervention, the recovery of lumbar and back function [Oswestry Disability Index (ODI) and Macnab score], surgical efficacy (NaKa grading), nursing satisfaction, and readmission rate were compared between the two groups.Results:After three months, the ODI score of the observation group was lower than that of the control group, and the Macnab score was higher than that of the control group, the NaKa grading was better than that of the control group, with statistically significant differences ( P<0.05). In the observation group and control group, the total effective rate of surgery, nursing satisfaction, and readmission rate were 88.64% (78/88) vs. 67.05% (59/88), 94.32% (83/88) vs. 78.41% (69/88), 4.55% (4/88) vs. 17.05% (15/88), respectively. The total effective rate and nursing satisfaction of the observation group were higher than those of the control group, and the readmission rate was lower than that of the control group, with statistical differences ( P<0.05) . Conclusions:"Internet +" combined with multidisciplinary out of hospital management can effectively improve the recovery of lumbar function in hospital-home transitional period management of patients after lumbar internal fixation, enhance the surgical efficacy and nursing satisfaction, and reduce the readmission rate.

Objective To investigate the impact of overweight on the prognosis of patients with acute mild ischemic stroke or moderate-high risk transient ischemic attack (TIA). Methods A total of 366 patients with acute mild ischemic stroke or moderate-high risk TIA who carried CYP2C19 loss-of-function alleles were included in the study. Baseline data were collected at admission, and clinical outcomes were collected within 3 months post-onset (primary outcomes: stroke recurrences within 3 months post-onset; secondary outcomes: composite outcome of stroke recurrence or death within 3 months post-onset, vascular events, and quality of life within 3 months). Kaplan-Meier method was used to plot the cumulative incidence curve of outcomes. Multivariate Cox proportional hazards model and multivariate Logistic regression model were used to evaluate the relationship between overweight and clinical outcomes within 3 months post-onset in patientswith ischemic stroke or TIA. The integrated discrimination improvement index (IDI) and net reclassification improvement index (NRI) were calculated to assess the predictive value of adding body mass index (BMI, whether overweight or not) based on traditional models for predicting the prognosis of acute ischemic stroke or TIA. Results After 3 months of follow-up, 28 patients had stroke recurrence, 1 patient died, and 31 patients had vascular events. The Kaplan-Meier cumulative incidence curve showed that the cumulative incidences of stroke recurrence, stroke recurrence or death, and vascular events after 3 months of onset were lower in overweight patients compared with non-overweight patients (Log-rank P < 0.05). Multivariate analysis showed that compared with non-overweight patients, overweight patients had significantly reduced risks of stroke recurrence within 3 months (HR=0.24; 95%CI, 0.08 to 0.71), composite outcome of stroke recurrence or death (HR=0.24; 95%CI, 0.08 to 0.69), and vascular events (HR=0.22; 95%CI, 0.07 to 0.63), and significantly improved quality of life within 3 months (OR=0.39; 95%CI, 0.20 to 0.76). The IDI and NRI calculations showed that compared with traditional models, the new model adding BMI (whether overweight) had significantly improved predictive ability for the prognosis of acute ischemic stroke or TIA. Conclusion Overweight may be a protective factor for the prognosis of TIA patients with acute mild ischemic stroke or moderate-high risk who carry CYP2C19 loss-of-function alleles. Compared with non-overweight patients, overweight patients have reduced risks of stroke recurrence, composite outcome of stroke recurrence or death, and vascular events within 3 months post-onset, and improved quality of life within 3 months post-onset.

OBJECTIVE: To study the anatomical characteristics of blood vessels in the lateral segment of the vertebral body through the surgical approach of oblique lumbar interbody fusion (OLIF) using MRI imaging, and evaluate its potential vascular safety zone. METHODS: The lumbar MRI data of 107 patients with low back and leg pain who met the selection criteria between October 2019 and November 2022 were retrospectively analyzed. The vascular emanation angles, vascular travel angles, and the length of vessels in the lateral segments of the left vertebral body of L ₁-L ₅, as well as the distance between the segmental vessels in different Moro junctions of the vertebral body and their distances from the edges of the vertebrae in the same sequence (bottom marked as I, top as S) were measured. The gap between the large abdominal vessels and the lateral vessels of the vertebral body was set as the lateral vascular safe zones of the lumbar spine, and the extent of the safe zones (namely the area between the vessels) was measured. The anterior 1/3 of the lumbar intervertebral disc was taken as the simulated puncture center, and the area with a diameter of 22 mm around it as the simulated channel area. The proportion of vessels in the channel was further counted. In addition, the proportions of segmental vessels at L ₅ without a clear travel and with an emanation angel less than 90° were calculated. RESULTS: Except for the differences in the vascular emanation angles between L ₄ and L ₅, the vascular travel angles between L ₁, L ₂ and L ₄, L ₅, and the length of vessels in the lateral segments of the vertebral body among L ₁-L ₄ were not significant ( P>0.05), the differences in the vascular emanation angles, vascular travel angles, and the length of vessels between the rest segments were all significant ( P<0.05). There was no significant difference in the distance between vessels of L ₁, L ₂ and L ₂, L ₃ at Moro Ⅰ-Ⅳ junctions ( P>0.05), in L ₃, L ₄ and L ₄, L ₅ at Ⅱ and Ⅲ junction ( P>0.05). There was no significant difference in the vascular distance of L ₂, L ₃ between Ⅱ, Ⅲ junction and Ⅲ, Ⅳ junction, and the vascular distance of L ₃, L ₄ between Ⅰ, Ⅱ junction and Ⅲ, Ⅳ junction ( P>0.05). The vascular distance of the other adjacent vertebral bodies was significant different between different Moro junctions ( P<0.05). Except that there was no significant difference in the distance between L ₂I and L ₃S at Ⅰ, Ⅱ junction, L ₃I and L ₄S at Ⅱ, Ⅲ junction, and L ₂I and L ₃S at Ⅲ, Ⅳ junction ( P>0.05), there was significant difference of the vascular distance between the bottom of one segment and the top of the next in the other segments ( P<0.05). Comparison between junctions: Except for the L ₃S between Ⅰ, Ⅱ junction and Ⅱ, Ⅲ junction, and L ₅S between Ⅰ, Ⅱ junction and Ⅱ, Ⅲ and Ⅲ, Ⅳ junctions had no significant difference ( P>0.05), there were significant differences in the distance between the other segmental vessels and the vertebral edge of the same sequence in different Moro junctions ( P<0.05). The overall proportion of vessels in the simulated channels was 40.19% (43/107), and the proportion of vessels in L ₁ (41.12%, 44/107) and L ₅ (18.69%, 20/107) was higher than that in the other segments. The proportion of vessels in the channel of Moro zone Ⅰ (46.73%, 50/107) and zone Ⅱ (32.71%, 35/107) was higher than that in the zone Ⅲ, while no segmental vessels in L ₁ and L ₂ were found in the channel of zone Ⅲ ( χ ²=74.950, P<0.001). Moreover, 26.17% (28/107) of the segmental vessels of lateral L ₅ showed no movement, and 27.10% (29/107) vascular emanation angles of lateral L ₅ were less than 90°. CONCLUSION L ₁ and L ₅ segmental vessels are most likely to be injured in Moro zones Ⅰ and Ⅱ, and the placement of OLIF channels in L _{4, 5} at Ⅲ, Ⅳ junction should be avoided. It is usually safe to place fixation pins at the vertebral body edge on the cephalic side of the intervertebral space, but it is safer to place them on the caudal side in L _{1, 2} (Ⅰ, Ⅱ junction), L _{3, 4} (Ⅲ, Ⅳ junction), and L _{4, 5} (Ⅱ, Ⅲ, Ⅳ junctions).
