Hepatitis B virus(HBV) infection is a severe health problem in the world.However,there is still not a satisfactory therapeutic strategy for the HBV infection.To search for new anti-HBV agents with higher efficacy and less side-effects,the inhibitory activities of traditional Chinese medicine Rheum palmatum L.ethanol extract(RPE) against HBV replication were investigated in this study.Quantitative real-time polymerase chain reaction(PCR) was employed to analyze the inhibitory activity of RPE against HBV-DNA replication in a stable HBV-producing cell line HepAD38; the expression levels of HBV surface antigen(HBsAg) and e antigen(HBeAg) were also determined by enzyme linked immunosorbent assay(ELISA) after RPE treatment.RPE could dose-dependently inhibit the production of HBV-DNA and HBsAg.The concentration of 50% inhibition(IC50) was calculated at 209.63,252.53 μg/mL,respectively.However,its inhibitory activity against HBeAg expression was slight even at high concentrations.RPE had a weak cytotoxic effect on HepAD38 cells(CC50 = 1 640 μg/mL) and the selectivity index(SI) was calculated at 7.82.Compared with two anthraquinone derivatives emodin and rhein,RPE showed higher ability of anti-HBV and weaker cytotoxicity.So Rheum palmatum L.might possess other functional agents which could effectively inhibit HBV-DNA replication and HBsAg expression.Further purification of the active agents,identification and modification of their structures to improve the efficacy and decrease the cytotoxicity are required.

BACKGROUND:Excessive apoptosis and decreased infiltration of cytotrophoblasts are essential causes for hypertension in pregnancy. Human placenta-derived mesenchymal stem cels contribute to damage repair, which has been shown in many studies, and moreover, human placenta-derived mesenchymal stem cels have a certain endocrine function and can act on the other tissues in an autocrine or paracrine manner. Therefore, we attempt to explore whether the human placenta-derived mesenchymal stem cel can repair damaged cytotrophoblasts, and then to gestational hypertension.
METHODS/DESIGN:This is a randomized controled cytological experiment. Human placenta-derived mesenchymal stem cel culture medium is colected and filtrated as human placenta-derived mesenchymal stem cel conditioned medium. Human cytotrophoblasts, JEG-3 cels, are cultured and randomized into three groups:15% normal pregnant serum is added in control group; 15% serum from severe pre-eclampsia patients is added in gestational hypertension model group; and in condition medium group, 15% serum from severe pre-eclampsia patients is added for 24 hours of culture, and then human placenta-derived mesenchymal stem cel conditioned medium containing 15% serum from severe pre-eclampsia patients is used instead. Flow cytometry is used to detect cel apoptosis rate.
DISCUSSION: This study wil help to find the feasibility of cel transplantation for gestational hypertension by exploring the effect of human placenta-derived mesenchymal stem cels on cytotrophoblasts function in gestational hypertension.
ETHICAL APPROVAL: The protocol is approved by the Ethics Committee of Shenyang Central Hospital of Shenyang Medical University. Informed consent is obtained from normal and pre-eclampsia women in pregnancy.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

Objective To observe endoplagmic reticulum stress in bone tissue of fluomsis rats and further explore the pathogenesis of skeletal fluorosis.Methods 48 Wistar rats were divided into 4 groups according to their body mass.The control and low.calcium group were fed with normal diet(0.79%calcium)and low-calcium diet(0.79%calcium)respectively,and both drank tap water(sodium fluoride concentrations<1 mg/L).High fluoride and low.calcium plus high-fluoride groups were fed with normal diet(0.79%calcium)and low-calcium diet (0.79%calcium)respectively,and both drank tap water containing sodium fluoride(sodium fluoride concentrations 221 mg/L).During experimental period,rats were measured body mass once a week with a stand diet and water available ad libiturn.The experimental period was 3 months.The biochemical techniques were used to test the indicators of oxidative stress and ALP in seFum of fluorosis rats.The total RNA was extracted from the one side of the femur,and the transcription level of Bip,Xbp1,CHOP and PDI were investigated by reverse transcription polymerase chain reaction(RT-PCR).Results The level of MDA in serum of low-calcium plus high-fluoride group wag higher than that of the control[(14.74±3.11)μmol/L vs(10.15±1.96)μmol/L,P<0.05];the activity of GPx was ma~edly higher in hish-fluoride group compared with the control[(3.87±0.41)×103 U/L vs(2.85± 0.55)×103 U/L,P<0.05];the level of uric acid in sel'um was significantly lower both in high-fluoride group and low-calcium plus high-fluoride group compared with the respective control and the low-calcium group[(73.95± 9.52)μmol/L vs(110.43±25.48)μmol/L,(54.32±22.09)μmol/L vs(101.71±17.01)μmol/L,P<0.05]. The activity of ALP wag obviously higher in low-calcium plus high-fluoride group compared with the control [(24.77±4.57)×103U/L vs (12.91±3.97)×103U/L,P<0.01)].The mRNA expression of Bip/GAPDH in bone tissue was markedly higher in bone of high-fluoride group and low-calcium plus high-fluoride group compared with the control(1.38±0.24,1.35±0.12 vs 1.14±0.06,P < 0.05). The expression of Xbp1/GAPDH in bone tissue significantly increased in low-calcium plus high-fluoride groups compared with the control and the low-calcium group (1.48±0.20 vs 1.02±0.25,1.07±0.25,P < 0.05 or < 0.01);and CHOP/GAPDH in bone tissue significantly increased in low-calcium plus high-fluoride groups compared with the control(0.84±0.18 vs 0.52±0.07,P < 0.05 ). Conclusions Accelerated osteogenetic action is seen in fluorosis rats,accompanied by oxidative stress and bone endoplasmic reticulum stress,which is likely involved in the pathogenesis of skeletal fluorosis.
