ABSTRACT
With reference to the comprehensive evaluation system for the clinical effectiveness of Chinese patent medicine， this paper summarized the current status and problems of the comprehensive evaluation of the clinical effectiveness of traditional Chinese medicine （TCM） in the treatment of malignant tumors from seven aspects， including safety， effectiveness， cost-effectiveness， innovation， suitability， accessibility， and TCM features. On this basis， the characteristics of TCM and the disciplinary characteristics of oncology are considered， and multiple sources of evidence， focus on dominant groups of people， consideration of economic toxicity， paying attention to post-marketing research， targeting at patients' willingness of medication， anchoring the supply of TCM services， and introducing symptoms threshold events are further emphasized. Moreover， methods such as nested case-control studies， enrichment designs， real-world research， and intelligent TCM diagnosis and treatment platforms are used to obtain high-level clinical evidence， ultimately building a scientific， homogeneous， and standardized comprehensive evaluation system for the clinical effectiveness of TCM in the treatment of malignant tumors.
ABSTRACT
Human rotavirus has been discovered since the early 1970s, which is still a primary pathogen causing infant diarrhea under the age of five. Each year about 600,000 infant died of severe body dehydration caused by rotavirus infection. Since the current rotavirus diarrhea have no specific therapeutic drugs, using vaccine to prevent rotavirus infection is an effective method. Research on a vaccine often involved in a multidisciplinary theory and technology. This article reviewed the epidemic situation of rotavirus,animal model,the body's immune response after infection, developing and using vaccine and other related issues.
ABSTRACT
To obtain a recombinant human plasminogen (hPLG) with potential anti-platelet aggregation activity, we cloned the cDNA coding Pro544 to Asn791 of hPLG, a kringle-deficit derivative (hPLG-deltaK). The Pro559 in activation loop was then mutated into Asp559 to provide Arg-Gly-Asp (RGD) motif. The constructed pPICZalphaA-RGD-HPLG-deltaK plasmid was expressed in yeast Pichia pastoris GS115, which produced RGD-hPLG-deltaK about 0.160 g/L broth. After affinity chromatography, the purity of the recombinant protein reached above 90%. Western blotting test confirmed that it retained the immunological reaction capability as human PLG. Its urokinase activation rate in 24 hours and its fibrinolytic activity made no deference against native hPLG-deltaK (P=0.630, n=5). Importantly, after activation by urokinase, RGD-hPLG-deltaK showed a significantly higher platelet aggregation inhibition rate (Ri) (21.8% +/- 1.57%) than hPLG-deltaK (3.8% +/- 0.33%) (P=0.000, n=5). These results proved that we constructed an hPLG mutant with anti-platelet aggregation activity, which made a foundation for developing innovative thrombolytic drugs with multifunction.
