This study aimed to provide scientific evidence for predicting quality markers(Q-markers) of Elephantopus scaber by establishing UPLC fingerprint of E. scaber from different geographical origins and determining the content of 13 major components, as well as conducting in vitro anti-cancer activity investigation of the main components. The chromatographic column used was Waters CORTECS UPLC C_(18)(2.1 mm×150 mm, 1.6 μm), and the mobile phase consisted of acetonitrile and 0.1% formic acid solution(gradient elution). The column temperature was set at 30 ℃, and the flow rate was 0.2 mL·min~(-1). The injection volume was 1 μL, and the detection wavelength was 240 nm. The UPLC fingerprint of E. scaber was fitted using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(2012 edition) to determine common peaks, evaluate similarity, identify and determine the content of major components. The CCK-8 assay was used to explore the inhibitory effect of the main components on the proliferation of lung cancer cells. The results showed that in the established UPLC fingerprint of E. scaber, 35 common peaks were identified. Thirteen major components, including neochlorogenic acid(peak 1), chlorogenic acid(peak 2), cryptochlorogenic acid(peak 3), caffeic acid(peak 4), schaftoside(peak 6), galuteolin(peak 9), isochlorogenic acid B(peak 10), isochlorogenic acid A(peak 12), isochlorogenic acid C(peak 18), deoxyelephantopin(peak 28), isodeoxyelephantopin(peak 29), isoscabertopin(peak 31), and scabertopin(peak 32) were identified and quantified, and a quantitative analysis method was established. The results of the in vitro anti-cancer activity study showed that deoxyelephantopin, isodeoxyelephantopin, isoscabertopin, and scabertopin in E. scaber exhibited inhibition rates of lung cancer cell proliferation exceeding 80% at a concentration of 10 μmol·L~(-1), higher than the positive drug paclitaxel. These results indicate that the fingerprint of E. scaber is highly characteristic, and the quantitative analysis method is accurate and stable, providing references for the research on quality standards of E. scaber. Four sesquiterpene lactones in E. scaber show significant anti-cancer activity and can serve as Q-markers for E. scaber.

Antrodia camphorata, a well-known and highly valued edible medicinal mushroom with intriguing activities like liver protection, has been traditionally used for the treatment of alcoholic liver disease. A. camphorata shows highly medicinal and commercial values with the demand far exceeds the available supply. Thus, the petri-dish cultured A. camphorata (PDCA) is expected to develope as a substitute. In this paper, nineteen triterpenes were isolated from PDCA, and thirteen of them were the unique anthroic acids in A. camphorata, including the main content antcin K, which suggested that PDCA produced a large array of the same anthroic acids as the wild one. Furthermore, no obvious acute toxicity was found suggesting the edible safety of PDCA. In mice alcohol-induced liver injury model, triglyceride (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and malondialdehyde (MDA) had been reduced by the PDCA powder as well as the main content antcin K, which indicated that the PDCA could protect alcoholic liver injury in mice model and antcin K could be the effective component responsible for the hepatoprotective activities of PDCA against alcoholic liver diseases.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.

Objective To study the effect of hypoxia on proliferation and invasion in non-small-cell lung cancer cell line A549 and its molecule mechanism.Methods The non-small-cell lung cancer cell line A549 were stimulated under hypoxia and normoxia for 24 hours in vitro.The proliferation ability was detected by CCK8.The invasion ability was detected by Transwell assay.The mRNA and protein expression levels of HIF-1 oα and β-catenin were detected by RT-PCR and Western blot.Furthermore,β-catenin siRNA was used to investigate the role of β-catenin on hypoxia induced proliferation and invasion.Results The results demonstrated that hypoxia could promote A549 cells proliferation and invasion.The mRNA and protein level of HIF-1oα and β-catenin was upregulated by hypoxia treatment,whereas β-catenin siRNA could block these processes.Conclusion Hypoxia can promote the proliferation and invasion of non-small-cell lung cancer cell line A549 by activating Wnt/β-catenin signaling pathway.

OBJECTIVETo evaluate the efficacy and safety of entecavir maleate (ETV) versus ETV in Chinese patients with hepatitis B e antigen(HBeAg)-positive chronic hepatitis B(CHB).

METHODSThe patient population of this previously published randomized, double-blind, double-dummy, controlled, multicenter study was expanded by patients in the 0.5 mg/day ETV maleate group (total n = 110) and patients in the 0.5 mg/day ETV group (total n = 108). At treatment weeks 12, 24 and 48, hepatitis B virus (HBV) DNA levels were measured by the Roche Cobas Ampliprep/Cobas Taqman PCR assay. Adverse events (AE) were recorded.

RESULTSAs in the original analysis, the two treatment groups showed similar characteristics at baseline. In addition, the results for the all therapeutic effects showed identical trends to the results obtained in the original analysis, including the statistically similar effects of ETV and ETV maleate treatment-induced decreases in mean HBV DNA level at weeks 12, 24, and 48 (ETV: by 4.28, 5.00, and 5.53 log10 IU/ml vs. ETV maleate: by 4.46, 4.99, and 5.51 log10 IU/ml, respectively; all vs. baseline P more than 0.05), achievement of undetectable levels of serum HBV DNA ( less than 20 IU/ml) at week 48 (ETV: 38.18% vs. ETV maleate: 35.19%; P more than 0.05), HBeAg loss rates at week 48 (ETV: 10.91% vs. ETV maleate: 12.96%; P more than 0.05), HBeAg seroconversion rates at week 48 (ETV: 7.77% vs. ETV maleate: 10.38%; P more than 0.05), normalization of alanine aminotransferase at week 48 (ETV: 75.47% vs. ETV maleate: 82.86%; P more than 0.05), and overall incidence of AE (ETV: 18.02% vs. ETV maleate: 17.43%; P more than 0.05).

CONCLUSIONPerforming analysis of the therapeutic efficacies of entecavir maleate versus entecavir with a larger study population confirmed our original findings of similar efficacy and safety profiles for these two drugs in patients with HBeAg-positive CHB.

Objective To explore the demographic characteristics and clinical features of patients with idiopathic pulmonary arterial hypertension ( IPAH ) in China.Methods Between March 2007 and September 2010,IPAH diagnosis was confirmed by right heart catheterization in 150 adult patients from 31 clinical centers in China.Clinical and hemodynamic data were analyzed and patients were divided into WHO functional class Ⅰ / Ⅱ and WHO functional class Ⅲ/Ⅳ group.Results The mean age of 150 patients were 36 ± 13 years with female patient/male patient ratio of 2∶1,and mean BMI was ( 21.3 ± 3.5 ) kg/m2.Fatigue (n =123,82.0％ ) and dyspnea ( n =112,74.7％ ) are the most common symptoms.Accentuated pulmonic second sound ( P2 ) was detected in 92.0％ ( n =138 ) of patients during physical examination,which was also the most common sign.About 49.0％ ( n =73 ) patients were WHO functional class Ⅰ/ Ⅱ patients and 46.0％ ( n =68 ) patients were WHO functional class Ⅲ/Ⅳ patients. Six minutes walking distance (6MWD) and Borg dyspnea score was (337 ± 101 ) m and 2.0 (2.0,4.0),respectively.Right ventricular hypertrophy was suggested by ECG in 93.1％ ( n =140 ) patients.Right atrial pressure was (10 ±6) mm Hg,mean pulmonary artery pressure was (61 ±16) mm Hg,cardiac index was (2.3 ±0.8)L · min-1 · m-2 and pulmonary vascular resistance(1484 ±699) dyn · s-1 · cm-5 in this cohort.6 MWD (305 m ±89 m vs.377 m ±88 m) was significantly shorter while Borg dyspnea score [3.0 (3.0,5.0) vs.2.0 (2.0,3.0) ] was significantly higher in WHO functional class Ⅲ/Ⅳ patients than in WHO functional class Ⅰ/Ⅱ patients. Similarly hemodynamic parameters were also worse in WHO functional class Ⅲ/Ⅳ patients than in WHO functional class Ⅰ / Ⅱ patients ( all P ＜ 0.05).Conclusion Idiopathic pulmonary arterial hypertension patients in this cohort affect mostly young adults,dominated by female gender and lower body mass index. Fatigue and dyspnea are the most common symptoms and accentuated pulmonic second sound ( P2 ) is the most common sign.IPAH patients are often displaying severe functional and hemodynamic disturbance at first visit to hospitals.Dyspnea and hemodynamic impairment are related to 6MWD and WHO functional class.
