RESUMO
Acute liver failure (ALF) is one of the most critical liver diseases in clinical practice and seriously affects the life and health of Chinese people. Due to its high morbidity and mortality rates, unclear pathogenesis, and limited treatment methods, ALF has become a major problem that needs to be solved urgently in the field of liver diseases. In recent years, more and more studies have shown that endoplasmic reticulum stress is a key biological process in the progression of ALF, and the IRE1α/TRAF2/JNK pathway, as a part of endoplasmic reticulum stress signaling, plays a role in amplifying inflammatory response, promoting hepatocyte apoptosis, and inhibiting liver regeneration ability during the progression of diseases. As a traditional treasure of China, traditional Chinese medicine has become a research hotspot in search for effective prevention and treatment drugs for ALF from monomers of Chinese herbs. This article elaborates on the mechanism of action of the IRE1α/TRAF2/JNK pathway in the progression of ALF and summarizes the potential value of several monomers of Chinese herbs in regulating this pathway, such as salidroside, Fructus Broussonetiae, Fructus Psoraleae+Schisandra chinensis, baicalein, genipin, kaempferol, resveratrol, sea buckthorn polysaccharide extract, and luteol, in order to provide a reference for further research and clinical practice of ALF.
RESUMO
This review focuses on the structure, function and pathological role of leukocyte function-associated antigen-1 (LFA-1) which is a heterodimeric protein consisting of two subunits. LFA-1 plays a most important role in the immune system including adhesion, extravasation, migration, apoptosis, cytotoxicity, cytokine production, and proliferation of lymphocytes. Therefore, T-cell activation can be suppressed by blocking ICAM-1/LFA-1 interaction in autoimmune diseases and organ transplantation. Many different inhibitors (i.e. antibodies, peptides, small molecules) have been demonstrated to block ICAM-1/LFA-1 interaction, and some of them are promising for medical treatment or have reached clinical trials.

OBJECTIVE:To explore the effect of Xiaoyu anshen capsule on the space learning-memory ability of chronic stress-induced depressed model rats.METHODS:The enrolled rats were divided into 6 groups:blank control group,model group,Fluoxetine group,Xiaoyu anshen capsule groups(high,medium and low dose).Chronic depression rat model was induced by chronic stress and isolated breeding.Water-maze video tracking analysis system was used to detect the capacity of rats' space learning-memory,and the indexes such as the body weight of rats before and after modeling and the consumption of sucrose,etc.were measured.RESUTLS:Compared with the blank control group,the model control group showed significantly decreased space learning-memory capacity,significantly lower in body weight increase and significantly less sucrose solution consumption.Compared with the model control group,the high,medium and low dose Xiaoyu anshen capsule-treated group showed significantly shortened escape latency,the high and medium dose groups showed increased number of times of crossing the hidden platform and body weight increase,and in high dose Xiaoyu anshen capsale group sucrose consumption increased.CONCLUSION:Xiaoyu anshen capsule is a nootropic Chinese herbal medicine for its inhibitory effect on the abnormality in body weight and sucrose solution consumption of chronic stress-induced depressed model rats and their action in enhancing the space learning-memory ability.
RESUMO
Objective To investigate the effects of DanzhiⅠ on rats acute skin trauma model.Method Perforate back of the rats was made with special puncher to establish acute trauma model.Wound surface was applied with Danzhi Ⅰ and the healing process was observed.Result Danzhi Ⅰ significantly shrinked the rim of raw surface and shorten the time of healing.The number of completely healed rats increased obviously.Conclusion Danzhi Ⅰ can significantly accelerate the healing of acute skin trauma of rats.
