Aim To investigate the effect of the total flaconoids extracted from Xiaobuxin-Tan g ( XBXT-2 )
on the hyperactivity of hypothalamic-pituitary-adrenal axis in mouse learned helplessness model. Methods Learned helplessness was induced by inescapable foot shock stress over 1h session for 5 days. After screen-ing, we divided learned helplessness mice into five groups:IS, inescapable shock;Dlx, dulxetine(20 mg ·kg-1);XBXT-2(25,50 mg·kg-1). Latency to es-cape shocks and escape failure had been recorded. During the test, Dlx(20 mg·kg-1 ) and XBXT-2(25, 50 mg·kg-1 ) were administered intragastrically once daily for four days. Serum corticosterone level and ad-renocorticotropic hormone ( ACTH ) level were meas-ured by ELISA, and expression of glucocorticoids re-ceptor ( GR) α/β and brain-derived neurotrophic fac-tor ( BDNF ) in hippocampus was determined using Western blot method. Results XBXT-2 (25,50 mg·
kg-1 ) or duloxetine treatment showed antidepressant effect in mouse learned helplessness model, as demon-strated by the decreased escape failure and escape la-tency. Our ELISA results showed that XBXT-2 or du-loxetine significantly decreased serum corticosterone level and its upstream stress hormone ACTH level in learned helplessness mice. Furthermore, Western blot result demonstrated XBXT-2 treatment increased GRs and BDNF expression in hippocampus. Conclusions XBXT-2 produces significant antidepressant effect on learned helplessness mice. In addition, the modulation of HPA axis produced by XBXT-2 may be important mechanism underlying its antidepressant-like effect in mouse learned helplessness model.

Hepatocellular carcinoma (HCC) is a primary malignant tumor of the liver and has a complex pathogenesis. At present, the oxidative stress theory is one of the many important theories for the mechanism of the development and progression of this disease. Autophagy is an important way for cells to clear misfolded proteins or damaged organelles and maintain homeostasis of the internal environment. An increasing number of evidence has shown that autophagy plays an important role in liver fibrosis and HCC and is closely associated with oxidative stress. With reference to the latest research findings around the world, this article analyzes the interaction between autophagy and oxidative stress in the pathogenesis of HCC from the aspect of their relationship with HCC. It is pointed out that the molecular mechanism by which autophagy regulates oxidative stress in the development of HCC may become a research hotspot in the future; it may provide a new means for the early diagnosis and treatment of HCC to activate or block a key pathway through which autophagy regulates oxidative stress.

A large number of studies have shown that berberine exerts an anti-tumor effect mainly by inhibiting cancer cell proliferation, inducing cancer cell death, inhibiting cancer cell metastasis and invasion, regulating the expression of endogenous oncogenes and tumor suppressor genes, affecting the activity of cancer-related enzymes, exerting an anti-oxidative stress effect, correcting abnormal glucose metabolism, and inhibiting the activity of nuclear factor-kappa B and its pathways. In vivo and in vitro studies have shown than berberine has a marked clinical effect in the treatment of hepatocellular carcinoma with various pharmacological actions and molecular regulatory mechanisms. This article reviews the role and mechanism of berberine, an active component of traditional Chinese medicines including Coptis chinensis, in the treatment of hepatocellular carcinoma and thus reveals the clinical effect of berberine in the treatment of hepatocellular carcinoma. In future, new dosage forms should be developed to improve its bioavailability and form effective therapeutic regimens for clinical application.

The incidence rate of nonalcoholic fatty liver disease (NAFLD) continues to rise around the world, and due to its complex pathogenesis, there is still a lack of effective treatment drugs. If NAFLD is not treated in time, it may increase the risk of related metabolic diseases such as diabetes and hyperlipidemia and even lead to liver fibrosis and liver cirrhosis. Glucagon-like peptide-1 is a hormone secreted by L-shaped cells of the small intestine and can regulate glucose-dependent stimulation of insulin secretion, reduce gastric emptying, and inhibit food intake. This article reviews the effect of glucagon-like peptide-1 receptor agonist in the treatment of NAFLD and related mechanism.

Objective: To explore the function of NLRP1 in noninfectious pulmonary injury (nonIPI) after allogeneic stem cell transplantation (allo-HSCT) . Methods: In this study, we established the model of allo-HSCT with C57BL/6 and NLRP^-/- mouse as recipients. Chimera rate was measured by flow cytometry. The HE staining was used to observe the pathology changes in the lungs. NLRP1 and relevant inflammatory proteins were measured by Western Blot. Results: On the day 14 after allo-HSCT, the chimera rate was more than 96%, HSCs of donors had been successfully transplanted into recipients. HE staining showed that nonIPI occurred after allo-HSCT. The degrees of injuries reached the peak on day 21. In addition, the expressions of MPO, NLRP1, p20, Mature-IL-1β and Mature-IL-18 had same tends with the degrees of nonIPI. When we knocked out NLRP1 gene of recipients, the degrees of nonIPI reduced and the expressions of MPO, p20, Mature-IL-1β and Mature-IL-18 were less than in non-knockout group. Conclusion allo-HSCT could cause nonIPI and high expressions of MPO, p20, IL-1β, IL-18, NLRP1. Knocking out NLRP1 gene could alleviate the degrees of nonIPI and reduce the expressions of relevant inflammatory proteins, indicating that NLRP1 might be one of factors contributed to nonIPI after allo-HSCT.

ObjectiveTo investigate the mechanism and effect of Qingfei Paidu decoction on transient receptor potential vanilloid-1/Transient receptor potential ankyrin1 （TRPV1/TRPA1） based on heat-sensitive channel and inflammatory response. MethodAccording to body weight， 80 8-week-old C57BL/6 mice were randomly divided into the normal group， model group， dexamethasone group （5 mg·kg^-1）， and low-dose， medium-dose， and high-dose groups of Qingfei Paidu decoction （14.865， 29.73， 59.46 g·kg^-1）， with 12 mice in each group. In addition to the normal group， the other groups were administered 20 μL （1×10^-3 g·kg^-1） to each mouse by airway infusion to establish the acute lung injury （ALI） model. In the administration group， the drug was given 1 h after modeling and again after an interval of 24 h. The lung tissue was taken 36 h after modeling. Double lung wet/dry weight ratio（W/D）， hematoxylin-eosin （HE） staining， enzyme-linked immunosorbent assay （ELISA）， and Western blot were used to observe and detect the pathological changes of lung tissue， expression levels of inflammatory cytokine tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）， and expressions of TRPV1 and TRPA1 proteins in heat-sensitive channel， nuclear factor kappa-B （NF-κB）， inhibitor of NF-κB （IκBα） in inflammatory pathway， and phosphorylated proteins. The phosphorylated protein/total protein ratio was calculated. ResultCompared with that in the normal group， the lung tissue of mice in the model group was seriously damaged， and pulmonary capillary permeability increased. Alveolar capillary congestion and dilation destroyed the complete structure of the alveolar， and the alveolar wall thickened. A large number of inflammatory cells and red blood cells were infiltrated， and pulmonary edema was significantly aggravated. The expressions of TNF-α， IL-6， TRPV1， TRPA1， phosphorylated NF-κB p65/NF-κB p65， and phosphorylated IκBα/IκBα were significantly increased （P<0.01）， and the whole lung W/D was significantly increased （P<0.01）. Compared with the model group， the dexamethasone group and low-dose， medium-dose， and high-dose groups of Qingfei Paidu decoction could significantly improve pulmonary edema. TNF-α， IL-6， TRPV1， TRPA1， lung tissue NF-κB p65， and IκBα phosphorylated protein/total protein ratio decreased significantly （P<0.05， P<0.01）. The whole lung W/D also decreased significantly （P<0.05， P<0.01）. ConclusionQingfei Paidu decoction has anti-inflammatory and protective effects on LPS-ALI mice， which can effectively reduce inflammation， induce diuresis， and alleviate edema. Its mechanism may be related to the regulation of the expression of TRPA1 and TRPV1 and the inhibition of the activation of the NF-κB pathway.
