OBJECTIVE:To explore the medication rules of TCM complex formulas for anti-experimental liver injury. METH-ODS:Usingexperimental liver injuryTCM complex preparationsprotection effectas themes,related literatures about medi-cation rules of TCM complex formulas for anti-experimental liver injury in CJFT,Wanfang database and VIP database were re-trieved,and general information,distribution,use frequency and co-occurrence frequency of single herbal medicine were descrip-tively analyzed. K-means clustering model and Apriori in SPSS Modeler were adopted for cluster analysis(clustering side and im-portance)and correlation analysis in medicines with top 10 use frequency. RESULTS:498 related literatures were retrieved,and 70 valid literatures were involved totally,including 51 TCM complex formulas and 111 Chinese herbal medicines. It was mainly drug for clearing heat,restoring vital energy and blood circulation. Drugs for clearing heat were most widely used(34 varieties),drugs for restoring vital energy showed the highest use frequency,with 63 times(25.82%);Prunella vulgaris had the highest frequency in single herbal medicines(accounting for 25.49%);and P. vulgaris-Salvia miltiorrhiza had the highest co-occurrence frequency in drug pairs. 5 clustering sides were obtained in clustering analysis,which were P. vulgaris-S. miltiorrhiza-Angelica sinensis- Glycyr-rhiza uralensis,Astragalus membranaceus-A. sinensis-Hedyotis diffusa,Artemisia scoparia-Curcuma wenyujin-Plygonum cuspida-tum,P. vulgaris-S. miltiorrhiza-A. scoparia,Schisandra chinensis-G. uralensis. Importance prediction showed,S. chinensis was the most important and P. cuspidatum was the least important. 13 drug pair rules were obtained from correlation analysis,and both sup-port and confidence degrees were low. CONCLUSIONS:The TCM complex formulas for anti-experimental liver injury are mainly based on drugs for clearing heat and restoring vital energy,while the compatibility is varied,and correlation degree is relatively low.

In order to investigate the change in and relationship between endothelin 1(ET 1) and nitric oxide(NO) in hypoxic pulmonary hypertension(HPH),the content of ET 1 and NO in plasma and lung tissue homogenate, the expression and localization of ET 1, constitutive and inducible nitric oxide synthase(cNOS,iNOS) using immunohistochemistry in HPH of rats were assayed. The effect of NOS inhibitor nitro L arginine methyl ester(L NAME) on the content of ET 1 was also studied. The results showed that the content of ET 1 and NO in plasma of the HPH rats were significantly higher than that of controls; positive expression of ET 1 and iNOS were enhanced in the endothelium of vessels, the epithelium of bronchi and the smooth muscle of vessels and bronchi,but the expression of cNOS weakened The content of ET 1 in plasma and lung tissue homogenate were increased after administration of L NAME. The results indicate that in the normal animals, NO may suppress the secretion of ET 1. The increased ET 1 may play an important role in the development of HPH, and the induced iNOS may be the result of functional adaptation to chronic hypoxia.

Background and purpose: Itch protein is an established regulator of T cell immune response thresholds, belong to a class of E3 ubiquitin-transferring enzymes, widely involve in the ubiquitination of several key signaling molecules, such as ZAP70, P85, VAV, PLC-γ, PKC-θ, etc, plays a critical role in tumor induced immu-nosuppression. Itch ligase activity regulate T-cell anergy and development of regulatory T cells in the periphery by modulating key components of T-cell receptor and transforming growth factor-βsignaling. Therefore, manipulation of Itch activities may provide the opportunities to develop future therapies for immune disorders such as autoimmunity and cancer. speciifc small interfering RNA(siRNA) was utilized to silence the expression of Itch gene of T-lymphocytes and investigate the cytotoxicity activity of transfected T lymphocytes against MFC stomach neoplasms cells in vitro. Methods:T lymphocytes were isolated from the spleen of 615 mice and transfected by speciifc siRNA to silence the expression of Itch gene, The expression of Itch protein were examined by Western bolt in each group;72 hours after transfection, The secretion level of IL-2, INF-γwere measured by enzyme-linked immunosorbent assay (ELISA). At the end, the cytotoxicity activity changes against MFC stomach neoplasms cells was compared between transfected T lym-phocytes, negative control and blank control in vitro. Results:Compared with control group, the expression rate of Itch protein of transfected T-lymphocytes was decreased to 16%after transfection 48 hours;72 hours after transfection, the secretion level of IL-2 in transfection group, negative control and blank control respectively were (1 891.96±141.91)pg/mL, (1 241.69±91.67)pg/mL and (1 175.03±89.14)pg/mL (P<0.001), the secretion level of INF-γin transfection group, negative control and blank control respectively were (958.33±75.46)pg/mL, (683.33±66.67)pg/mL and (691.72±68.72) pg/mL (P<0.05). Transfected T lymphocyte also showed more efifcient killing ability against MFC stomach neoplasms cells than negative control and blank control in vitro, the highest killing rate has reached (54.18±2.96)%. Conclusion:Silencing Itch gene can signiifcantly promoted the secretion level of IL-2, INF-γof mice T lymphocyte, enhanced the cytotoxicity activity of T lymphocyte against MFC stomach neoplasms cells in vitro.

Objective To explore the protective effects of electro-acupuncture (EA) serum onβ-amyloid protein (Aβ) induced primary rat hippcampal neurons. Methods The rat models of Alzheimer's disease were established by intracerebral injection of Aβ1-40. After treated them with EA, the serum was harvested. Primary cultured hippocampal neurons were treated with Aβ25-35 to establish neuronal damage model in vitro, and divided into normal group, model group and EA serum group. The proliferation of neurons was detected by MTT test. Neuronal apoptosis was examined by TUNEL staining, and expression of cysteine aspartic acid proteases-3 (Caspase-3) was detected by immunocytochemical staining. Results MTT test showed that the cell viability was significantly decreased after treated with Aβ. While compared with the model group, cell proliferation of EA serum group was significantly enhanced (P<0.01). TUNEL staining showed that the number of apoptotic cells in EA serum group decreased significantly compared with the model group (P<0.01). After 48 h of Aβ treatment, Caspase-3 expression levels were significantly elevated. However, compared with the model group, the number of Caspase-3 positive cells in EA serum group was significantly reduced (P<0.01). Conclusion The EA serum could promote the proliferation of hippocampal neurons, reduce the expression of Caspase-3, counteract the neurotoxicity of β-amyloid protein, and reduce neuronal apoptosis.
