针对某反应堆临时开合顶盖的支座设计，提出一种新型可拆卸节点——夹持型节点。首先仿照钳盘式制动器的结构形式和工作原理设计了夹持型节点的具体构造，通过推导传力装置所传递的挤压力和摩擦力，阐述了节点的传力机理；然后通过确定螺栓力、螺栓扭矩及夹持结构的简化分析，提出了节点的简化设计方法；最后使用通用有限元分析软件ABAQUS对夹持型节点的受力性能进行有限元分析。结果表明：夹持型节点能满足连接强度要求且对所连接构件无损伤，理论上验证了夹持型节点的实用性和设计方法的可行性。研究可为类似的支座节点设计提供参考。

Objective　To investigate the clinical efficacy of Jiedu Huayu Hushen prescription in the treatment of acute－onchronic liver failure （ACLF) complicated by hepatorenal syndrome （HRS) and its effect on endotoxemia. Methods　Clinical data were collected from 96 patients with ACLF complicated by HRS who were diagnosed and treated in The First Affiliated Hospital of Guangxi University of Chinese Medicine from March 2020 to June 2022, and they were divided into observation group and control group using a random number table, with 48 patients in each group. In addition to comprehensive Western medicine therapy, the patients in the control group were given norepinephrine and albumin, while those in the observation group were given Jiedu Huayu Hushen prescription combined with norepinephrine and albumin, and the course of treatment was 2 weeks for both groups. The two groups were compared in terms of serum endotoxin level, traditional Chinese medicine （TCM) syndrome score, 24－hour urine volume, renal function, liver function, coagulation function, and clinical outcome. The independent－samples t test was used for comparison of continuous data between two groups, paired t－test was used for comparison before and after treatment within the group； and the chi－square test was used for comparison of categorical data between two groups. Results　Compared with the control group after 2 weeks of treatment, the observation group had a significantly lower TCM syndromes core （P<0.05), significantly lower levels of endotoxin, blood urea nitrogen, serum creatinine, cystatin C, and prothrombin time（ all P<0.05), and significantly higher levels of glomerular filtration rate, 24－hour urine volume, serum albumin, and prothrombin time activity （all P<0.05). After 2 weeks of treatment, the observation group had a significantly higher overall response rate than the control group （87.50% vs 66.67%, P<0.05). Conclusion　Based on comprehensive Western medicine therapy, Jiedu Huayu Hushen prescription can reduce serum endotoxin level, improve liver and renal function and coagulation function, and increase urine volume in patients with ACLF complicated by HRS, with a better clinical efficacy than Western medicine therapy alone.

[Objective] The aim of this paper is to study the effect of Naringenin ( NAR) on human immortalized HaCaT cells and its antioxidant activity. [Method] Cell activity was detected by MIT. H & E staining was used to observe the effect of naringin treatment on the morphology of oxidative damage HaCaT cells. Cell migration ability was detected by scratches. Cell proliferation was detected by cloning. Western blot was used to detect the protein expression. SOD and MDA levels were measured with the oxidation kit. [Result] Naringenin had no obvious inhibitory effect on the activity of HaCaT cells, and the migration of HaCaT cells damaged by H2O2 was accelerated after the intervention of naringienin. After the treatment of naringenin on HaCaT cells damaged by H2O2, the expression level of SOD and CDK protein increased, the activity of SOD increased and the content of MDA decreased. [Conclusion] Naringenin can restore the proliferation and migra-tion of HaCaT cells damaged by H2O2, affect the expression of SOD2 and CDK2 protein, improve SOD activity and reduce the content of MDA. Subsequently, it may be developed into a potential skin protective drug to delay aging. [ABSTRACT FROM AUTHOR]

Objective: To investigate the clinical effect of vitamin E (VE) and levetiracetam (LEV) on the epilepsy and serum levels of total antioxidant capacity (T-Aoc) and malondialdehyde (MDA) of patients. Methods: 134 cases with epilepsy who were treated in our hospital from June 2013 to September 2015 were selected and randomly divided into two groups. The patients in the control group were treated with LEV, while the patients in the observation group were treated with vitamin E on the basis of the control group. Then the clinical efficacy, the EEG background activity, plasma levels of T-Aoc and MDA of two groups were recorded and compared before and after the treatment, and the safety of treatment was also evaluated. Results: After the treatment, the total effective rate of observation group was 88.1%, which was higher than 74.6% in the control group (P<0.05). Compared with before treatment, the frequency of δ wave, and the θ wave of EEG in the two groups were increased, while the α wave frequency was decreased (P<0.05). After treatment, the improvement of EEG in the observation group was significantly better than that of the control group (P<0.05). Compared with before treatment, the plasma levels of T-Aoc in the observation group significantly increased, and the MDA decreased (P<0.01); In the control group, the plasma T-Aoc level slightly increased, and the MDA level slightly decreased, but the difference was not statistically significant (P>0. 05). Compared with control group, the improvement degree of oxidative stress indexes in the observation group were significantly better (P<0.01). The adverse reaction rate o f the observation group was 10.4%, which was higher than 7.5% in the control group, while there was no statistically significant difference (P>0.05). Conclusion: VE and LEV could effectively reduce the seizure frequency, improve the EEG background activity, balance oxidative/antioxidant system, and control recurrence in the treatment of in patients with epilepsy assisted treatment with high safety.
