Objective To investigate the effect of altered oxidative stress system on liver function after partial splenic embolization(PSE).Methods Twenty-nine patients with liver cirrhosis and hypersplenism who received PSE were selected.Peripheral venous blood was drawn from the patients before and at 1 week,1 month,and 3 months after PSE,and the indexes of oxidative stress system factors including malondialdehyde(MDA),superoxide dismutase(SOD),advanced oxidiation protein products(AOPPs),and gluta-thione peroxidase(GSH-Px)were detected,as well as liver function indexes.Results There were positive correlation between SOD activity and total bilirubin(TBil)and model for end-stage liver disease(MELD)scores at 1 week postoperatively(TBil:r=0.725,P＜0.05;MELD:r=0.764,P＜0.05).There was positive correlation between GSH-Px activity and alanine aminotransferase(ALT)at 1 month postoperatively(r=0.777,P＜0.05),however,the AOPPs was negatively correlated with ALT and aspartate aminotransferase(AST)at 3 months postoperatively(ALT:r--0.900,P＜0.05;AST:r=-0.957,P＜0.05).Conclusion PSE can improve the body oxidative stress system and enhance the body's antioxidant response,and then improve the liver function.

Objective:To construct a value evaluation framework for high-value medical consumables,providing a guidance for medical insurance access and hospital access management scenarios in China.Methods:It conducted literature review,qualitative in-terviews and quantitative surveys.A total of 12 experts were invited for qualitative interviews,while 100 experts from four fields of health technology assessment,medical insurance,hospital management,and clinical practice participated in the quantitative survey.Through those process,it generated the composition of the value framework and the scoring of each item.Differences in ratings be-tween different scenarios and experts were analyzed through chi-square tests.The recommendation level for each item was graded.Re-sults:A comprehensive value evaluation framework for high-value medical consumables was established,which included 6 core dimen-sions,comprised 16 items for secondary dimensions and 50 items for tertiary dimensions.It showed significant differences between the medical insurance access and hospital access scenarios,as well as among different fields of experts in the same scenario.furthermore,grading the items in two scenarios.The medical insurance access scenario had 8 highly recommended items,and the hospital access scenario had 24 highly recommended items.Conclusion:Value evaluation should encourage multi-dimensional assessments and inter-disciplinary participation,continually improving the management of high-value medical consumables in medical insurance and hospital access.

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.
