HPCAL1 is a novel driver of autophagy-dependent ferroptosis / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

自噬是细胞内一种高度保守的生理过程，可通过溶酶体系统降解过量或受损的细胞器、有毒的蛋白聚集体和病原体等。最新研究表明，海马钙素样1（HPCAL1）可作为特异性自噬受体和铁死亡的正调节因子。HPCAL1可选择性降解钙粘素2（CDH2），加速脂质过氧化，促进癌细胞铁死亡。iHPCAL1是抑制HPCAL1的小分子化合物，可抑制Erastin诱导的肿瘤细胞铁死亡。此外，它还可以抑制铁死亡诱导的急性胰腺炎。本文通过对HPCAL1在铁死亡中的具体作用机制进行概述，为HPCAL1作为铁死亡相关疾病的潜在治疗靶点提供新思路和理论依据。

Overview on Traditional Chinese Medicine syndrome differentiation and treatment of Coronavirus Disease 2019 (COVID-19) / 国际中医中药杂志

This paper reviews the Traditional Chinese Medicine (TCM) diagnosis and treatments for Coronavirus Disease 2019 (COVID-19) and the theories of different experts in TCM. The pathogenesis of COVID-19 involves dampness, toxin, heat, cold, blood stasis and deficiency. Dampness and poison were the core pathological factors. The treatment is based on the situation of patients in different regions and different stages of the disease, and focuses on dampness and toxin, with the purpose of eliminating evil and consolidating the foundation. Oral TCM prescriptions such as Qingfei-Paidu Decoction, Qingfei-Touxie-Fuzheng Decoction, Lianhua-Qingwen capsule (granule) show good curative effect. TCM non drug therapies, such as acupuncture, moxibustion, acupoint application, ear acupuncture, traditional exercises, etc., are mostly aimed at light, ordinary and convalescent patients, which can improve symptoms. However, high-quality TCM research is still needed.

Objective: To investigate the effect of self-etching adhesive with different unsealing time on the microleakage of the adhesive interface between tooth and resin. Methods: Unopened self-etching adhesives, Scotchbond Universal (S) and Xeno V+ (X) were respectively used to adhere Z350 resin for restoration of the prepared occlusal cavities sized 4 mm × 4 mm × 4 mm (n = 40) . The methylene blue staining method was used to observe the microleakage of the adhesive interface between the tooth and filling material at the instant moment, 1, 2 and 3 months after the self-etching adhesives was opened (n = 10) . Results: (1) Increase of microleakage in S group was found with the time span after unsealing, and there was a statistical difference between the instant moment and 3 months after unsealing (P＜0. 05) . (2) There was no significant difference at the 4 test time points in X group (P＞0. 05), although the microleakage value of the samples were increased with the increase of the time after unsealing. (3) The microleakage of X group was greater than that of S group at the instant moment and 1 month after unsealing (P＜0. 05) . Conclusion: Unsealing time may increase the microleakage of the adhesive interface between the tooth and the filling material, the effect varies with the types of the adhesives.
