Persimmon leaf flavonoid has been shown to enhance brain ischemic tolerance in mice, but its mechanism of action remains unclear. The bilateral common carotid arteries were occluded using a micro clip to block blood flow for 10 minutes. After 10 minutes of ischemic preconditioning, 200,100, and 50 mg/kg persimmon leaf flavonoid or 20 mg/kg ginaton was intragastrically administered per day for 5 days. At 1 hour after the final administration, ischemia/reperfusion models were estab- lished by blocking the middle cerebral artery for 2 hours. At 24 hours after model establishment, compared with cerebral ischemic rats without ischemic preconditioning or drug intervention, plasma endothelin, thrombomodulin and yon Willebrand factor levels significantly decreased and intercel- lular adhesion molecule-1 expression markedly reduced in brain tissue from rats with ischemic pre- conditioning. Simultaneously, brain tissue injury reduced. Ischemic preconditioning combined with drug exposure noticeably improved the effects of the above-mentioned indices, and the effects of 200 mg/kg persimmon leaf flavonoid were similar to 20 mg/kg ginaton treatment. These results indicate that ischemic preconditioning produces tolerance to recurrent severe cerebral ischemia. However, persimmon leaf flavonoid can elevate ischemic tolerance by reducing inflammatory reactions and vascular endothelial injury. High-dose persimmon leaf flavonoid showed an identical effect to ginaton.

BACKGROUND： The most prominent characteristic of brain aging is decreased learning and memory ability. The functions of learning and memory are closely related to intracerebral acetylcholinesterase （ACHE） and monoamine neurotransmitter activity. Previous studies have shown that Schisandra chinensis polysaccharide has an anti-aging effect. OBJECTIVE： To explore the effects of Schisandra chinensis polysaccharide on AChE activity and monoamine neurotransmitter content, as well as learning and memory ability in a D-galactose-induced aging mouse brain model compared with the positive control drug Kangnaoling. DESIGN, TIME AND SETTING： Completely randomized, controlled experiment based on neurobiochemistry was performed at the Pharmacological Laboratory, Henan University of Traditional Chinese Medicine from September to December 2003. MATERIALS： Schisandra chinensis was purchased from Henan Provincial Medicinal Company. Schisandra chinensis polysaccharide was obtained by water extraction and alcohol precipitation. Kangnaoling pellets were provided by Liaoning Tianlong Pharmaceutical （batch No. 20030804; state drug permit No. H21023095）. A total of 50 six-week-old Kunming mice were randomly divided into five groups： blank control, model, Kangnaoling, high and low dosage Schisandra chinensis polysaccharide groups, with 10 mice per group. METHODS： Mice in the blank control group were subcutaneously injected with 0.5 mL/20 g normal saline into the nape of the neck each day, while the remaining mice were subcutaneously injected with 5% D-galactose saline solution （0.5 mL/20 g） in the nape for 40 days to induce a brain aging model. On day 11, mice in the high and low dosage Schisandra chinensis polysaccharide groups were intragastrically infused with 20 mg/mL and 10 mg/mL Schisandra chinensis polysaccharide solution （0.2 mL/10 g）, respectively. Mice from the Kangnaoling group were intragastrically infused with 35 mg/mL Kangnaoling suspension （0.2 mL/10 g）, and the mice in the m

Postoperative tumor recurrence remains a predominant cause of treatment failure. In this study, we developed an in situ injectable hydrogel, termed MPB-NO@DOX + ATRA gel, which was locally formed within the tumor resection cavity. The MPB-NO@DOX + ATRA gel was fabricated by mixing a thrombin solution, a fibrinogen solution containing all-trans retinoic acid (ATRA), and a Mn/NO-based immune nano-activator termed MPB-NO@DOX. ATRA promoted the differentiation of cancer stem cells, inhibited cancer cell migration, and affected the polarization of tumor-associated macrophages. The outer MnO2 shell disintegrated due to its reaction with glutathione and hydrogen peroxide in the cytoplasm to release Mn2+ and produce O2, resulting in the release of doxorubicin (DOX). The released DOX entered the nucleus and destroyed DNA, and the fragmented DNA cooperated with Mn2+ to activate the cGAS-STING pathway and stimulate an anti-tumor immune response. In addition, when MPB-NO@DOX was exposed to 808 nm laser irradiation, the Fe-NO bond was broken to release NO, which downregulated the expression of PD-L1 on the surface of tumor cells and reversed the immunosuppressive tumor microenvironment. In conclusion, the MPB-NO@DOX + ATRA gel exhibited excellent anti-tumor efficacy. The results of this study demonstrated the great potential of in situ injectable hydrogels in preventing postoperative tumor recurrence.

Background : SHARPIN (SHANK- associated RH domain interactor) is a component ofthe linear ubiquitination complex that regulates the NF- κB signaling pathway. To betterunderstand the function of SHARPIN, we sought to establish a novel geneticallyengineered Syrian hamster with SHARPIN disruption using the CRISPR/Cas9 *** : A single- guide ribonucleic acid targeting exon 1 of SHARPIN gene was designedand constructed. The zygotes generated by cytoplasmic injection of the Cas9/gRNA ribonucleoprotein were transferred into pseudopregnant hamsters. Neonatalmutants were identified by genotyping. SHARPIN protein expression was detectedusing Western blotting assay. Splenic, mesenteric lymph nodes (MLNs), and thymicweights were measured, and organ coefficients were calculated. Histopathologicalexamination of the spleen, liver, lung, small intestine, and esophagus was performedindependently by a pathologist. The expression of lymphocytic markers and cytokineswas evaluated using reverse transcriptase- quantitative polymerase chain *** : All the offspring harbored germline- transmitted SHARPIN *** with wild- type hamsters, SHARPIN protein was undetectable in SHARPIN −/−hamsters. Spleen enlargement and splenic coefficient elevation were spotted inSHARPIN −/− hamsters, with the descent of MLNs and thymuses. Further, eosinophilinfiltration and structural alteration in spleens, livers, lungs, small intestines, and esophagiwere obvious after the deletion of SHARPIN. Notably, the expression of CD94 and CD22 was downregulated in the spleens of knockout (KO) animals. Nonetheless,the expression of CCR3, CCL11, Il4 , and Il13 was upregulated in the esophagi. Theexpression of NF- κB and phosphorylation of NF- κB and IκB protein significantly diminishedin SHARPIN −/− *** : A novel SHARPIN KO hamster was successfully established using theCRISPR/Cas9 system.

中药在疾病预防和治疗的过程中发挥重大作用,但部分中药在临床的长期应用过程中,给人体带来的不良反应也逐渐显现出来,肝损伤属于其中之一。肝损伤也是中药新药研发过程中作为临床安全用药的重要检查项目,已成为众多上市药物退出市场的重要原因。随着对中药临床用药安全性的关注增加,关于中药肝损伤研究日益增多,大多数研究集中于中药或者中药成分的肝脏损伤研究。为了提高中药的安全性,该文总结了部分致肝损伤中药的物质基础和机制及降低中药肝损伤的措施,包括减少给药剂量和疗程,改变给药途径,改变药物剂型,药物配伍和炮制等方法;此外该文还总结了防治各种诱导物诱发肝损伤的单体中药、中药复方和中药成分及防治肝损伤的生物效应和作用机制。结合现代致肝损伤中药的减毒研究,提出明确致肝损伤中药的安全剂量和“毒-效”界限,明确减毒措施的减毒机制及确定致肝损伤中药的毒性物质基础,为致肝损伤中药的临床应用提供安全性保障;结合中药防治肝损伤的研究,提出加强中药防治肝损伤的临床研究的同时,利用现代科学技术“从局部到整体”来阐释中药复方防治肝损伤的科学内涵,进而为临床防治肝损伤提供科学依据。
