To understand Lophatherum gracile plant community's structural characteristics, a survey of community structure and species diversity was conducted through quadrat sampling in Yongchuan district of Chongqing. The results showed that there were 386 species vascular plants, belonging to 117 families and 229 genera. Based on habitat, community structure and species composition, L. gracile were found in three community types: Pinus massoniana community, banboo community, shurb community. Vertical structure was composed of three layers, including tree layer, shrub layer and herb layer. Species in shrub layer was the richness. P. massoniana is the only dominant species of the community, it can not regenerate naturally, the shrub layer has a greater effect on the community of L. gracile in the future. In addition, the banboo community and shurb community is not stable because of human's activity. Therefore, the community characters of L. gracile should be taken care of conservation when the resources are utilized.

This study was aimed to investigate the expression levels of TRF1, TRF2 and RAP1 mRNA in peripheral blood mononuclear cells of patients with acquired aplastic anemia, and to explore their relation with onset of acquired aplastic anemia. Peripheral blood mononuclear cells of 40 patients with acquired aplastic anemia and 20 normal subjects as control were collected to detect mRNA expression of TRF1, TRF2 and RAP1 by using real-time quantitative polymerase chain reaction. The results showed that the expression levels of TRF1 and RAP1 in peripheral blood mononuclear cells of patients with acquired aplastic anemia were significantly higher than that in normal controls (P < 0.05), while the expression level of TRF2 was lower than that in normal controls (P < 0.01). There was significant correlation between TRF2 and RAP1 expressions level (r = 0.522, P = 0.001). It is concluded that the changes in expression levels of TRF1, TRF2 and RAP1 may play a role in the pathogenesis of acquired aplastic anemia.

OBJECTIVE To study the pharmacokinetics change of schisandra chinensis under the pathological condition of liver dysfunction for safe and rational use of herbal medicines. METHODS The metabolism of four effective lignans from schisandra chinensis(SC), schisandrin,schisantherin A, deoxyshisandrin and γ-schisandrin was studied using microsomes from patients with advanced hepato-cellular carcinoma. In situ intestinal and hepatic perfusions were conducted to clarify the contributions from impairments of gut and liver on the pharmacokinetics of the four schisandra lignans in CCl4-intoxi-cated rats.The metabolism in rat and human liver microsomes and transport in Caco-2 monolayer cell model were studied to reveal the key factors for the in vivo disposition of the four lignans. RESULTS When SC alcoholic extract was orally administrated to CCl4-intoxicated rat for a short term (4 d), the pharmacokinetics of four active SC lignans was significantly changed while its hepatoprotective effect was not obviously observed.The plasma concentrations of the four schisandra lignans were dramatical-ly elevated compared with the control.The Cmax,AUC and MRT were all increased or prolonged signif-icantly while parameter CLz/F was obviously reduced in rat pretreated with CCl4. In hepatic perfusion study and liver microsomes incubation,it was found that the hepatic metabolism of the four lignans was markedly decreased mainly due to the activity reduction of multiple CYP450 isoenzymes involved the metabolism, which, eventually, might lead to the alternation of their pharmacokinetic profiles in CCl4-intoxicated rats or patients with advanced hepatocellular carcinoma. CONCLUSION The pharmacoki-netic studies of SC components in pathological situation of liver dysfunction are expected to provide useful data for rational and safe application of SC preparations in clinic or further pharmacological and toxicological research.

To investigate the risk factors of hepatic encephalopathy in patients with liver failure. Nine-hundred-and-seventy-six hepatitis B virus (HBV) patients with liver failure were retrospectively analyzed. Clinical data (sex, age, family history, liver cirrhosis, diabetes, celiac infection, pulmonary infection, liver kidney syndrome, upper gastrointestinal hemorrhage) and laboratory findings (albumin, globulin, total bilirubin, direct bilirubin, alanine aminotransferase, aspartate aminotransferase (AST), gamma-glutamyl transferase, alkaline phosphatase, cholesterol, cholinesterase, K+, Na+, creatinine, international normalized ratio (INR), alpha-fetoprotein, HBV DNA, white blood cell, hemoglobin, platelet) were collected and used to screen the risk factors for hepatic encephalopathy by univariate and multiple regress analyses. Multiple logistic regression analysis indicated that upper gastrointestinal hemorrhage [risk (R) = 0.993, relative hazard (RH) = 2.699, 95% confidence interval (CI): 1.567-4.651], pulmonary infection [R = 1.043, RH = 2.839, 95% CI: 1.680-4.797], INR [R = 0.257, RH = 1.293, 95% CI: 1.220-1.370], AST level [R = 0.001, RH = 1.001, 95% CI: 1.000-1.001], and cirrhosis [R = 0.569, RH = 1.815, 95% CI: 1.112-2.965] were closely correlated with hepatic encephalopathy. HBV-infected patients presenting with upper gastrointestinal haemorrhage, pulmonary infection, prolonged INR, elevated AST, or liver cirrhosis should be carefully monitored for indications of hepatic encephalopathy to initiate timely therapeutic interventions.
