The dominant eye is the eye that plays a significant role in visual perception.It plays an essential role in binocular vision and fusion functions with a complex formation mechanism.According to the principle of the dominant eye examination method, ocular dominance can be classified into sighting, motor, and sensory dominance.Changes in visual acuity or visual function due to the unbalanced progression of binocular disease may lead to the switch in the dominant eye, affecting the balance of binocular vision and the therapeutic effect.Therefore, misjudging or neglecting of the dominant eye will change the long-term visual balance between the eyes, which may affect people's visual quality and quality of life.These aspects are mainly represented in the process of refractive error correction, refractive surgery, strabismus correction surgery, amblyopia training methods and cataract intraocular lens measurement.The formulation of medical plans based on the strategy of the dominant eye can remarkably improve the reconstruction good binocular vision and the quality of life of patients.However, the role of the dominant eye in binocular vision is not fully understood, and clinicians are not sufficiently aware of its importance.Therefore, this study will review the latest research progress on the mechanism of dominant eye formation, examination methods, and clinical significance of dominant eye switching.

Objective Genotypes(G)1,3,and 5 of the Japanese encephalitis virus(JEV)have been isolated in China,but the dominant genotype circulating in Chinese coastal areas remains unknown.We searched for G5 JEV-infected cases and attempted to elucidate which JEV genotype was most closely related to human Japanese encephalitis(JE)in the coastal provinces of China. Methods In this study,we collected serum specimens from patients with JE in three coastal provinces of China(Guangdong,Zhejiang,and Shandong)from 2018 to 2020 and conducted JEV cross-neutralization tests against G1,G3,and G5. Results Acute serum specimens from clinically reported JE cases were obtained for laboratory confirmation from hospitals in Shandong(92 patients),Zhejiang(192 patients),and Guangdong(77 patients),China,from 2018 to 2020.Seventy of the 361 serum specimens were laboratory-confirmed to be infected with JEV.Two cases were confirmed to be infected with G1 JEV,32 with G3 JEV,and two with G5 JEV. Conclusion G3 was the primary infection genotype among JE cases with a definite infection genotype,and the infection caused by G5 JEV was confirmed serologically in China.

Objective:To analyze the growth characteristics of different genotypes of Japanese encephalitis virus (JEV) in different cell lines, and to provide scientific basis for the selection of cell lines in the study of JEV.Methods:BHK-21, Vero, C6/36, PK-15, DF-1, N2a, SH-sy5y and MDCK cell lines were selected. The proliferation ability of genotype 1 (NX1889 strain), genotype 3 (P3 strain) and genotype 5 (XZ0934 strain) JEV in these cell lines was evaluated by plaque assay and RT-qPCR.Results:Significant cytopathogenic effects (CPE) were observed in BHK-21, Vero, C6/36, DF-1, N2a and PK-15 cell lines across all three JEV genotypes. However, no significant differences in CPE characteristics were observed within the same cell line. SH-sy5y and MDCK cell lines did not show significant CPE, but virus proliferation was detected in SH-sy5y cell line, while MDCK cell line were found to be insensitive to JEV. No significant difference was observed in the proliferation curves of G1, G3 and G5 JEV in BHK-21, Vero and SH-sy5y cell lines. In C6/36 and PK-15 cell lines, the titer of G1 JEV was higher than that of G3 and G5. In DF-1 cell line, G5 demonstrated a higher titer than the other two genotypes, whereas in N2a cell line, G5 showed a lower titer than the other two.Conclusions:There are differences in the proliferation of three different genotypes of JEV in different cell lines, which can provide reference for the study of JEV in different directions.

Objective:To analyze the clinical, genetic mutation characteristics, and treatment prognosis of type 2A hereditary hemochromatosis (HH) in China.Methods:Peripheral blood samples and clinical data of patients with primary iron overload were collected through the China Registry of Genetic/Metabolic Liver Disease from June 2015 to November 2023. HH-related genes were detected by Sanger sequencing. Clinical characteristics and gene mutation characteristics of HH patients carrying HJV gene mutations were analyzed.Results:Among the 37 cases with primary iron overload, ten cases (27.0%, 10/37) had detectable HJV gene mutations, which included four homozygous mutations, five compound heterozygous mutations, and one monoheterozygous mutation. p.Q6H and p.C321X (80.0%, 8/10) were the most common mutated sites. The average age of onset was 30.7±14.7 years. The age of diagnosis was 35.7±16.2 years, with male-to-female ratio of 7:3. Ferritin and transferrin saturation were (5 267±905) ng/ml, and 94.3%±1.2%, respectively. Magnetic resonance imaging showed iron overload in the liver, pancreas, and myocardium. Liver biopsy showed diffuse iron deposition within hepatocytes. All ten cases had elevated transaminases; one case (1/10, 10.0%) had liver cirrhosis; four cases (4/10, 40.0%) had heart failure and arrhythmia; five cases (5/10, 50.0%) had diabetes; six cases (6/10, 60.0%) had hypogonadism; six cases (6/10, 60.0%) had skin pigmentation; and six cases (6/10, 60.0%) had fatigue symptoms. All six cases underwent bloodletting therapy, and ferritin levels dropped to about 100 ng/ml. Two cases of oral administration of the iron chelator deferasirox did not meet the ferritin level standard, and one case died from acute heart failure following a confirmed diagnosis during hospitalization.Conclusion:The HJV gene may be one of the main pathogenic genes of HH in China. The p.Q6H and p.C321X mutations were one of the hotspot mutations. The onset age of HJV gene-related HH was between 20 and 30 years old, and their condition was severe. Therefore, early bloodletting treatment can have a favorable outcome.

Severe acute pancreatitis (SAP) is a serious disease commonly encountered in the emergency department and can precipitate systemic inflammatory response syndrome and multiple organ dysfunction syndrome with high morbidity and mortality. However, its etiology and pathogenesis are complex and have not been fully elucidated. Clinical studies can provide some data on the etiology, pathophysiology, and outcome associated with the disease. However, research on SAP cannot be carried out in humans directly for ethical considerations. It is very important to establish an appropriate animal model of SAP to elucidate its pathogenesis and seek innovative therapeutic methods. In this paper, we reviewed the latest research progress at home and abroad in animal models of SAP over the past several years.

Objective:To investigate the efficacy of iRoot BP Plus pulpotomy versus root canal therapy for the management of cariously exposed pulp in deciduous molars. Methods:A total of 62 teeth from eligible patients who received treatment at Hefei Stomatological Clinical College (Hefei Stomatological Hospital), Anhui Medical University between September 2021 and March 2022 were selected for the study. These teeth were randomly treated either with iRoot BP Plus pulpotomy (pulpotomy group, n = 31) or root canal therapy (root canal therapy group, n = 31). Follow-up examinations were conducted at 6, 12, and 18 months post-treatment to compare the success rates of treatment between the two groups. Results:The success rates of treatment at 6, 12, and 18 months post-treatment in the pulpotomy group were 100.0% (31/31), 100.0% (31/31), and 96.8% (30/31), respectively, while in the root canal therapy group, they were 100.0% (31/31), 93.5% (29/31), and 80.6% (25/31). The success rates in the pulpotomy group were significantly higher than those in the root canal therapy group at both 12 and 18 months post-treatment, with a statistically significant difference observed at 18 months (χ2 = 4.02, P < 0.05). Conclusion:The iRoot BP Plus pulpotomy procedure yields a more favorable and stable outcome compared with root canal therapy for managing cariously exposed pulp in deciduous molars.

Objectives:To investigate the screening status of warning signs for mental and behavioral development (WS) and influencing factors of infants and young children (IYC) in poverty eliminated regions of Henan Province.Methods:This study was a cross-sectional study. A total of 15 680 IYC aged 6-23 months from 51 poverty eliminated counties in Henan province from June to September of 2023 were selected through a multi-stage random sampling method. IYC′s early warning signs were screened using the WS checklist (WSC). Children′s socio-demographic characteristics, maternal information, birth status, and illness conditions such as fever and diarrhea within 2 weeks were measured through a uniformly designed questionnaire. All participants also received the measurement of height, weight, and hemoglobin concentration level. Logistic regression model was used to explore the influencing factors of positive WSC and conducted sensitivity analyses.Results:Among the sample of 15 680 IYC, there were 8 462 boys (53.97%) and 7 218 girls (49.03%), with their age of (15±5) months. A total of 291 (1.86%) IYC were positive in WSC. Parenting risk ( OR=5.07, 95% CI 3.93-6.52, P<0.001) and preterm birth ( OR=1.63, 95% CI 1.06-2.52, P=0.027) were both positively associated with the odds of WSC′s positivity. Being girls ( OR=0.66, 95% CI 0.52-0.85, P=0.001), age (12-17 months, OR=0.47, 95% CI 0.35-0.62, P<0.001; 18-23 months, OR=0.40, 95% CI 0.30-0.54, P<0.001), and maternal educational level (junior high school, OR=0.46, 95% CI 0.32-0.66, P<0.001; senior high school or vocational high school, OR=0.35, 95% CI 0.23-0.56, P<0.001; college and above, OR=0.36, 95% CI 0.23-0.57, P<0.001) were all negatively associated with the risk of WSC′s positivity. Sensitivity analyses demonstrated that, after excluding anemic children, the association between preterm birth and WSC′s positivity was not significant ( OR=1.54, 95% CI 0.95-2.49, P=0.081). Despite this situation, being girls, age and maternal educational level were still negatively associated with the odds of WSC′s positivity (all P<0.05); preterm birth, parenting risk were remained positive associated with the risk of WSC′s positivity (all P<0.05) either by excluding children with protein-energy malnutrition or 2-week morbidity, or using prevalence ratio instead of OR. Conclusions:Among the IYC in poverty eliminated regions of Henan Province, the risk of positivity of WSC was higher for those IYC with parenting risk, preterm birth, boys, younger age, and lower maternal education level. These influencing factors, such as gender, age, preterm birth, parenting risk and maternal educational level, were in certain stability across different IYC characteristics and estimation models.

OBJECTIVE: To design and construct a graphene oxide (GO)/silver nitrate (Ag₃PO₄)/chitosan (CS) composite coating for rapidly killing bacteria and preventing postoperative infection in implant surgery. METHODS: GO/Ag₃PO₄ composites were prepared by ion exchange method, and CS and GO/Ag₃PO₄ composites were deposited on medical titanium (Ti) sheets successively. The morphology, physical image, photothermal and photocatalytic ability, antibacterial ability, and adhesion to the matrix of the materials were characterized. RESULTS: The GO/Ag₃PO₄ composites were successfully prepared by ion exchange method and the heterogeneous structure of GO/Ag₃PO₄ was proved by morphology phase test. The heterogeneous structure formed by Ag₃PO₄ and GO reduced the band gap from 1.79 eV to 1.39 eV which could be excited by 808 nm near-infrared light. The photothermal and photocatalytic experiments proved that the GO/Ag₃PO₄/CS coating had excellent photothermal and photodynamic properties. In vitro antibacterial experiments showed that the antibacterial rate of the GO/Ag₃PO₄/CS composite coating against Staphylococcus aureus reached 99.81% after 20 minutes irradiation with 808 nm near-infrared light. At the same time, the composite coating had excellent light stability, which could provide stable and sustained antibacterial effect. CONCLUSION GO/Ag₃PO₄/CS coating can be excited by 808 nm near infrared light to produce reactive oxygen species, which has excellent antibacterial activity under light.

Objective:To investigate the risk factors of depression in patients with lacunar cerebral infarction 3 months after discharge, and build a risk prediction model.Methods:The clinical data of 237 patients with lacunar cerebral infarction diagnosed and treated in the Second Affiliated Hospital of Wannan Medical College from January 1, 2021 to January 1, 2022 were retrospectively analyzed. Demographic data, laboratory indicators and risk factors of cardiovascular disease were collected when the patients were admitted to hospital. The patient health questionnaire-9 (PHQ-9) score was used to assess the risk of post-stroke depression (PSD) 3 months after discharge. Univariate and multivariate logistic regression analyses were used to identify independent risk factors of depression. A predictive model was constructed based on the above risk factors. The predictive efficacy was evaluated by receiver operating characteristic (ROC) curve, and the clinical applicability of the predictive model was measured by calibration curve and decision curve.Results:Fifty-four patients with lacunar infarction (22.80%) showed symptoms of depression at 3 months after discharge. Multivariate logistic regression showed that women ( OR=2.952, 95% CI: 1.403-6.213, P=0.004), cystatin C ( OR=2.964, 95% CI: 1.222-7.191, P=0.016), apolipoprotein B ( OR=4.836, 95% CI: 1.533-15.258, P=0.007) were the independent risk factors for PSD in patients with lacunar infarction. Activity of daily living (ADL) score ( OR=0.939, 95% CI: 0.915-0.964, P<0.001) was a protective factor for PSD in patients with lacunar infarction. The area under the curve (AUC) of the prediction model was 0.779 (95% CI: 0.703-0.855, P<0.001), which was better than other predictors. Hosmer-Lemeshow H test showed that the model was well calibrated ( P=0.588). In addition, the prediction model of decision curve analysis had a good clinical applicability. Conclusions:The predictive model based on gender, laboratory indicators and daily life ability score can evaluate the risk of PSD in patients with lacunar infarction 3 months after discharge. It is good predictive efficacy and clinical applicability which worth clinical promotion and application.

Objective:To retrospectively compare the clinical efficacy of two PDE3 inhibitors, oplinone and Milrinone, in order to evaluate which drug has better effects on the improvement of cardiac function, protection of renal function and adverse effects of arrhythmia.Methods:A total of 41 neonates with congenital heart disease after biventricular treatment under cardiopulmonary bypass in the Department of Cardiothoracic Surgery at Soochow University Children's Hospital during 2018-2022 were collected. The experimental group was divided into two groups: Oprilinone(25 cases) and Milinone(16 cases). A retrospective study was conducted on the incidence of renal function, cardiac function improvement and arrhythmia in the children.Results:On the first day after operation, EF in both groups decreased significantly compared with that before operation( P<0.01); On day 4 after surgery, EF in the oprilinone group was significantly higher than that on day 1 after surgery( P<0.01), Milrinone group was slightly higher than that on day 1 after surgery( P<0.05), and EF in oprilinone group was significantly higher than that in Milinone group during the same period( P<0.01); EF in Milinone group continued to increase on day 7 compared with day 4( P<0.01), but there was no significant difference between the two groups. Long-term follow-up showed that there was no significant difference in EF value in the oprilinone intervention group on day 7 after surgery( P<0.05), and the long-term EF in Milinone group was higher than that at 7 days after surgery( P<0.05). The creatinine level in the oprinone intervention group continued to decrease on the 4th and 7th day after surgery( P<0.01; P<0.05); The creatinine level of Milinone group on day 4 after surgery was significantly lower than that on day 1 after surgery( P<0.01), the decrease was not significant on the 7th day after surgery compared with the 4th day after surgery; The creatinine level in the oprilinone group was lower than that in the Milrinone group on day 7 after surgery( P<0.05). The rate of arrhythmia in children was slightly decreased in the intervention group of olplinone. There was no change in the Milinone group. Conclusion:Oplinone improved cardiac function better than Milrinone, and the recovery time to normal cardiac function was shorter. In terms of renal function protection, oplinone was stronger than Milrinone, and the protective effect of oplinone on kidney lasted longer. No significant abnormalities were found with respect to adverse reactions, such as the incidence of arrhythmia.
