Weeping forsythia is an important ornamental, ecological and medicinal plant. Brown leaf spots limit the large-scale production of weeping forsythia as a medicinal crop. Alternaria alternata is a pathogen causing brown leaf spots in weeping forsythia; however, its pathogenesis and the immune response mechanisms of weeping forsythia remain unclear.

The present study is to establish a quantitative analysis of multi-components by single marker(QAMS) for determining contents of seven compositions in Alismatis Rhizoma, alismoxide, alisol C 23-acetate, alisol A, alismol, alisol B, alisol B 23-acetate and 11-deoxy-alisol B. Six relative correction factors(RCFs) of alismoxide, alisol C 23-acetate, alisol A, alismol, alisol B and 11-deoxy-alisol B were established in the UPLC method with alisol B 23-acetate as the internal standard, which was to calculate the mass fraction of each. The mass fraction of seven effective constituents in Alismatis Rhizoma was calculated by the external standard method(ESM) at the same time.

Objective: To analyze the clinical characteristics of cytomegalovirus(CMV) infection after allogenic hematopoietic stem cell transplantation(allo-HSCT) and the effect of preemptive therapy.
Methods: A total of 134 patients who underwent allo-HSCT from March 2010 to March 2015 in the Department of Hematology of our hospital were enrolled in this study. The CMV infection rate, the median time of CMV infection occurence, and the risk factors for CMV infection after allo-HSCT, the response rate of preemptive treatment and the median time of CMV-DNA turning negative were analyzed.
Compared to Trichoderma reesei RUT-C30 cellulase (Trcel), Penicillium oxalicum 16 cellulase (P16cel) from the fermentation supernatant produced a 2-fold higher glucose yield when degrading microcrystalline cellulose (MCC), possessed a 10-fold higher β-glucosidase (BGL) activity, but obtained somewhat lower other cellulase component activities. The optimal temperature and pH of β-1,4-endoglucanase, cellobiohydrolase, and filter paperase from P16cel were 50-60 °C and 4-5, respectively, but those of BGL reached 70 °C and 5. The cellulase cocktail of P16cel and Trcel had a high synergism when solubilizing MCC and generated 1.

Beclin 1 is a key factor for initiation and regulation of autophagy, which is a cellular catabolic process involved in tumorigenesis. To investigate the role of alternative splicing of Beclin1 in the regulation of autophagy in leukemia cells, Beclin1 mRNA from 6 different types of cell lines and peripheral blood mononuclear cells from 2 healthy volunteers was reversely transcribed, subcloned, and screened for alternative splicing. New transcript variants were analyzed by DNA sequencing.

The protective effect of Astragalus membranaceus on myocardial hypertrophy has been extensively proved. To test the hypothesis that Astragaloside IV can ameliorate the myocardial hypertrophy and inflammatory effect induced by β-adrenergic hyperactivity, we carried out in vivo and in vitro experiments.

Despite its dual role in determining cell fate in a wide array of solid cancer cell lines, autophagy has been robustly shown to suppress or kill acute myeloid leukemia cells via degradation of the oncogenic fusion protein that drives leukemogenesis. However, autophagy also induces the demise of acute leukemia cells that do not express the known fusion protein, though the molecular mechanism remains elusive. Nevertheless, since it can induce cooperation with apoptosis and differentiation in response to autophagic signals, autophagy can be manipulated for a better therapy on acute myeloid leukemia.

In order to obtain a large amount of lipase, the lipase gene from Candida antarctica ZJB09193 was cloned, and expressed in Pichia pastoris with the vector pPICZαA. Under the optimal conditions, the yield of recombinant lipase in the culture broth reached 3.

This study was designed to characterize the differential protein expression in the progeny of human liver cells surviving exposure to ionizing radiation. The progeny of irradiated cells were derived from a human liver cell line exposed to 0, 2, 4, or 6 Gy of (60)Co gamma-irradiation. Total protein of the cells was extracted by two-dimensional electrophoresis (2-DE) and analyzed with ImageMaster 2D Platinum software.

This study examined the protein expression in lung tissues of rats exposed to radon and cigarette smoke using a proteomic approach. Male Wistar rats were exposed daily to radon at a concentration of 100,000 Bq/m(3) for 16 h, and then exposed to 20% cigarette smoke for 1 h for a period of 75 d, with the radon cumulative dose reaching 200 WLM (working level months). Proteins from rat lung tissue were separated by two-dimensional gel electrophoresis (2-DE), stained with Coomassie blue, and analyzed with ImageMaster two-dimensional (2D) platinum software.

The total proteins of lung tissue from Wistar rats exposed to radon for cumulative doses up to 100, 200, or 400 WLM (working level months) were isolated by two-dimensional electrophoresis (2-DE) and analyzed with ImageMaster 2D Platinum software. Comparison of the 2-DE images between the control and radon-exposed groups resulted in 14 upregulated and 9 downregulated protein spots, of which 15 were identified by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) or matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass spectrometry (MALDI-TOF/TOF-MS).
