BACKGROUND:The degradation of extracellular matrix, which is mediated by matrix metal oproteinases, plays a crucial role in the corneal neovascularization. Tissue factor pathway inhibitor 2, a new type serine proteinase inhibitor, can effectively inhibit the activity of matrix metal oproteinases.
OBJECTIVE:To elucidate the effect of tissue factor pathway inhibitor 2 on the expressions of matrix metal oproteinases in keratocytes in vitro.
METHODS:Rabbit keratocytes were primarily cultured and subcultured in vitro. Plasmid vector pBos-Cite-neo/TFPI-2 was transfected into keratocytes with Lipofectamine 2000. The positive cells were selected using G418.
RESULTS AND CONCLUSION:The results of reverse transcription-polymerase chain reaction, western blot analysis and gelatinase zymography analysis showed that, expression of mRNA and protein of tissue factor pathway inhibitor 2 was upregulated in the transfected keratocytes (P<0.05), while activity of matrix metal oproteinase 1 and 2 was significantly decreased (P<0.05). Experimental findings indicate that that tissue factor pathway inhibitor 2 strongly inhibits the activity of matrix metal oproteinase 1 and 2 in keratocytes.

Objective:To develop an E-chart visual acuity recognition card suitable for children aged 2-4 years and to design a child-friendly gamified intervention method to improve the success rate, compliance, and parental satisfaction in visual acuity testing for this age group.Methods:A non-concurrent historical control study design was employed, involving 143 children aged 2-4 years and parents who attended the ophthalmology outpatient clinic of Renmin Hospital of Wuhan University from January to June 2023. The children were divided into the control group and the intervention group based on their appointment times. Both groups underwent binocular visual acuity testing using the E-chart visual acuity recognition cards. The control group received conventional visual acuity testing, while the intervention group was subjected to a child-friendly gamified intervention. The effectiveness of the intervention was assessed by comparing the success rate of visual acuity testing, examination compliance, and parental satisfaction between the two groups.Results:Finally, the sample size of the control group and the intervention group were 69 and 74 cases. The children in the control group was (3.06 ± 0.47) years old, with 36 males and 33 females; whereas the children in the intervention group was (2.99 ± 0.45) years old, with 38 males and 36 females. The parents in the control group was (29.37 ± 4.00) years old, with 24 males and 45 females; whereas the parents in the intervention group was (29.35 ± 3.50) years old, with 27 males and 47 females. The success rate of visual acuity testing in the intervention group was significantly higher at 63.5% (47/74) compared to the control group′s 34.8% (24/69), with a statistically significant difference ( χ2=7.45, P<0.01). The compliance of the children during the examination in the intervention group, categorized as no grade I cases, 19 gradeⅡcases, 21 gradeⅢcases, and 34 grade Ⅳ cases, was significantly higher than that of the control group, which had 17 grade I cases, 23 gradeⅡcases, 15 grade Ⅲcases, and 14 grade Ⅳ cases ( Z=4.61, P<0.01). In terms of parental satisfaction, the intervention group′s satisfaction score was (4.53 ± 0.56) points, which was significantly higher than the control group′s score of (3.74 ± 0.78) points, indicating a statistically significant difference ( t=-4.88, P<0.01). Conclusions:The child-friendly gamified intervention significantly improved the success rate and compliance of visual acuity testing in children aged 2-4 years and increased parental satisfaction. This intervention provides an effective solution for visual acuity testing in children aged 2-4 years.

Objective: The aim of the study is to validate whether the Recognition Of Stroke In the Emergency
Room (ROSIER) scale can be used by general practitioners (GPs) in an emergency medical service
(EMS) protocol to transfer stroke patients from primary care center to advanced hospital with acute
stroke center. Methods: GPs prospectively performed the ROSIER scale and the Cincinnati Prehospital
Stroke Scale (CPSS) on suspected stroke patients as a transfer protocol. All patients were immediately
transferred to the Level-II hospital for further treatment. Results: 468 of the 512 suspected stroke
patients met the inclusion criteria in this study. The ROSIER scale showed a diagnostic sensitivity
of 83.13% (95% confidence intervals [CI] 79.74-86.52%) and specificity of 80.88% (95% CI 77.32-
84.44%). The CPSS showed a diagnostic sensitivity of 78.01% (95% CI 74.26-81.76%) and specificity
of 70.59% (95% CI 66.46-74.72%). The Kappa statistic value of the ROSIER scale and the CPSS
were 0.601 and 0.454, respectively. The area under the curve (AUC) of ROSIER scale was large than
the CPSS (AUC 0.855 vs. 0.791). However, the difference was not significantly different.
Conclusions: This study suggest that ROSIER and CPSS could be used in an EMS protocol to transfer
stroke patients from a primary care center to an advanced hospital offering thrombolysis service

AIM: To investigate the relationship between objective ocular torsion and near stereopsis in patients with primary superior oblique overaction(PSOOA).METHODS: Retrospective study. A total of 59 strabismus patients with PSOOA who underwent strabismus surgery at Renmin Hospital of Wuhan University between January 2019 and November 2023 were collected. Based on the collected fundus photographs and the position of the fovea relative to the horizontal line through the optic disc, the eyes were categorized as incyclotorsion, excyclotorsion, or no cyclotorsion. Additionally, the fovea-disc angle(FDA)and the relationship between objective ocular torsion status, FDA, and near stereopsis function in the patients were further measured and analyzed.RESULTS: Totally 59 patients(92 eyes)showed superior oblique overaction. There were no cases of excyclotorsion, 32 cases with no cyclotorsion, and 27 cases with incyclotorsion. The total binocular FDA was significantly smaller in the no-cyclotorsion group compared with the incyclotorsion group(2.83°±2.89° vs 16.12°±5.74°, P<0.001). The preservation rates of near stereopsis were 66% and 15% in the no-cyclotorsion and incyclotorsion groups, respectively, with a significant statistical difference(P<0.001), and the preservation rates of fine near stereopsis were 38% and 11% in the no-cyclotorsion and incyclotorsion groups, respectively, with a significant statistical difference(P=0.02). Among all patients, near stereopsis was correlated with total binocular FDA(r=-0.526, P<0.001), with the strongest correlation observed with the FDA of the incyclotorsion(r=-0.546, P<0.001). In the incyclotorsion group, there was no correlation between near stereopsis and total binocular FDA(r=-0.366, P=0.060), with a negative correlation between near stereopsis and the FDA of both the incyclotorsion and the overaction(r=-0.424, P=0.028; r=-0.485, P=0.010). In the no-cyclotorsion group, near stereopsis was not correlated with total binocular FDA, incyclotorsion FDA, or overaction FDA.CONCLUSION:PSOOA patients with incyclotorsion have a lower preservation rate of near stereopsis than those without cyclotorsion. Near stereopsis function of patients with PSOOA is negatively correlated with total binocular FDA, especially the greater the FDA of the incyclotorsion and overaction, the worse the near-stereoscopic function.
