There are multimechanism and multipathogens in the course of the progress and the metastasis of hepatocarcinoma Growth factors play an important role in the process. In this review, the relationship between growth factors and hepatocarcinoma are summarized.[

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

[ ABSTRACT] AIM:To investigate the protective effect of 1, 3-dicyclopentyl-1, 2, 3, 6-tetrahydropyrimidine-4, 5-dicarboxylic acid diethyl ester (ZL-5015) on lethal endotoxin-challenged mice and to explore the underlying mechanism. METHODS:Mouse model of lethal endotoxin challenge and endotoxemia were established by intraperitoneal administration of lipopolysaccharide (LPS) at a dose of 70 mg/kg to the C57BL/6J mice.Mouse peritoneal macrophages stimulated with LPS (10 mg/L) were used as an in vitro inflammatory model.The levels of interleukin-1β( IL-1β) , interleukin-10 ( IL-10) and tumor necrosis factor-α(TNF-α) were measured by enzyme-linked immunosorbent assay (ELISA).Real-time PCR was used to evaluate the mRNA expression of the cytokines.RESULTS:Prophylactic treatment of the mice with ZL-5015 (100 and 200 mg/kg, ig) slightly increased the survival rate, extended the survival time, decreased the serum levels of IL-1βand TNF-α, and increased the serum level of IL-10 in the early stage of endotoxemia as compared with model group.The results of in vitro study demonstrated that treatment of the endotoxin-stimulated mouse peritoneal macrophages with ZL-5015 (10, 20 and 40μmol/L) inhibited the expression of IL-1βand TNF-αat both mRNA and protein levels but promoted the expression of IL-10 at both mRNA and protein levels.CONCLUSION: The tetrahydropyrimidine derivative ZL-5015 shows a moderate anti-endotoxin effect by increasing the survival rate and extending the survival time of the mice challenged by endotoxin, which may result from inhibition of the expression of pro-inflammatory cytokines such as IL-1βand TNF-α, and promotion of the expression of anti-inflammatory cytokine IL-10.

Objective To study the chemical constituents from the roots of Euphorbia sonngarica. Methods Compounds were isolated by Sephadex LH-20,MPLC,and silica gel column chromatographies. Their structures were identified by spectral methods together with physicochemical analysis.Results Eleven compounds were isolated from the roots of E.sonngarica.They were identified as cryptomeridiol (Ⅰ),betulin(Ⅱ),betulinic acid(Ⅲ),3?-hydroxy-olean-12-en-28-oic acid(Ⅳ),7-oxo-?sitosterol (Ⅴ),erythrinasinate(Ⅵ),octaeosanoie acid(Ⅶ),1-octacosene(Ⅷ),24-methene-cycloartenol(Ⅸ),eu- phol(Ⅹ),?-sitosterol(Ⅺ).Conclusion CompoundsⅠ-Ⅷare isolated from this plant for the first time.

Objective: To learn the epidemiological characteristics of infectious disease related public health emergencies in Zhejiang Province from 2010 to 2018 for the prevention and control. Methods: The surveillance data was extracted from National Public Health Emergency Management Information System. Descriptive epidemiology method was used to analyze main diseases as well as distribution characteristics of time and places. Results: A total of 445 events were reported, which caused 14362 cases and 34 deaths, with a attack rate of 0.69% and mortality rate of 0.24%. There were 298 events with less than 30 cases, accounting for 66.97%. The event classification was dominated by general events ( 242 events, 54.38% ) and ungraded events ( 201 events, 45.17% ). The main diseases were chickenpox ( 134 events, 30.11% ), hand foot mouth disease ( 59 events, 13.26% ) and other infectious diarrhea ( 51 events, 11.46% ). The incidence peaked from April to June ( 129 events, 28.99% ) and from November to December ( 131 events, 29.44% ). Ningbo ranked the top in the number of reported events ( 141 events, 31.69% ). Most events ( 322 events, 72.36% ) occurred in schools. Conclusions The infectious disease related public health emergencies in Zhejiang Province from 2010 to 2018 were mainly caused by chickenpox, hand-foot-mouth disease and other infectious diarrhea. The two peaks of the emergencies occurred from April to June and from November to December. Ningbo was the main area reporting infectious diseases, and schools were the main places.

Objective To obtain highly purified oligodendrocyte precursor lineage cells in vitro and make identification.Methods The oligodendrocyte precursors were separated from astrocyte by orbital shaker and further purified by differential adhesion,and finally cultured in chemically defined serum-free medium,with appended neurotrophin 2(N2),platelet-derived growth factor(PDGF),basic fibroblast growth factor(bFGF).Immunofluorescence assay was applied to identify the separated cells with A2B5,O4,O1 and glial fibrillary acidic protein(GFAP) antibodies.Results Over 95% of cultured oligodendrocyte precursor cells were obtained.The oligodendrocyte progenitors were A2B5 and O4 positive,immature oligodendrocytes were O4 and O1 positive while GFAP were negative.Conclusions Separation and purification by shaking and differential adhesion and chemically defined medium are suitable and effective to obtain highly purified oligodendrocyte precursor cells.Cell output will increase notabily and rest in immature phase by appending both N2,PDGF and bFGF.
