Objective To study the clinicopathological significance of the expression of glutameta decarboxylase 65(GDA65) and protein kinase C(PKC) in the central cancer tissues, cancer edge tissues, paracancerous liver tissue and non-cancer liver tissues. Methods The expression of GDA65 and PKC were detected by immunohistochemical method in 10% neutral formalin- fixed and routinely paraffin-embedded sections in 37 hepatic cancer specimen. Results The positive rate and the score of GDA65 and PKC in the cancer tissues were significantly higher than that in the paracancer tissues or non-cancer liver tissues, but the PKC expression was no difference between the central cancer tissues and the cancer edge tissues . The expression of GDA 65 was related to the pathological types, differentiated degrees, liver cirrhosis or metastasis of hepatocarcinomas. No correlation was found between the expression of PKC and the clinicopathological features of hepatocarcinomas. Conclusions The expression of GDA65 and PKC might be closely related to the carcinogenesis of hepatocarcinoma, they might be important biological markers of hepatocarcinoma.

Objective To study the effect of expression of myoglobin which mediated by adenovirus,on ATP value of liver and the protective effect on liver ischemia reperfusion injury.Methods Adenovirus carrying CMV promoter sequences linked to the human myoglobin gene(AdCMVMyo) were transfected into rats liver. Then myoglobin, hepatic ATP levels and liver function were evaluated. Results Myoglobin expression was verified in rat livers after AdCMVMyo transfection. The ATP levels in rat livers 72 hours after AdCMVMyo transfection were significantly higher than that in control group(P

ObjectiveTo explore the spatial distribution patterns of flavonoid glycosides in Epimedium sagittatum and the influences of environmental factors on the accumulation of these components. MethodsThe spatial statistical analysis and GeoDetector model were used to analyze the distribution patterns of epimedin A,epimedin B,epimedin C,icariin,and total flavonoid glycosides in E. sagittatum samples from 92 different production areas in 36 cities of 13 provinces/municipalities/autonomous regions of China,as well as the effects of 28 environmental factors on the accumulation of each component. ResultsThe average content of flavonoid glycosides 64 (69.56%) producing areas and 30 (83.33%) cities met the quality standard of no less than 1.50% of total flavonoid glycosides in the 2020 edition of Chinese Pharmacopoeia.Epimedin A,epimedin B,epimedin C,icariin,and their sum showed significantly high accumulation.The hot spots regions of epimedin A and epimedin B were similar with each other,mainly located in western Hunan,eastern Hubei,eastern Guizhou,and northern Guangxi.The common hot spot areas of epimedin C and total flavonoid glycosides were in western and southwestern Hunan,southern Henan,northern Anhui,eastern Guizhou,and southern Chongqing.The hot spots areas of icariin were in southern Chongqing,western Hunan,and eastern and northeastern Guizhou.The interactions between environmental factors had stronger explanatory power for the accumulation of components than single factors.The strongest single factor and interactive factor affecting the accumulation of epimedin C were precipitation of wettest quarter (q=0.16) and its interaction with temperature seasonality (q=0.35),respectively.The strongest single factor influencing both the accumulation of icariin and total flavonoid glycosides was the precipitation of coldest quarter (q equals 0.15 and 0.22,respectively).The strongest interactions were observed between precipitation of coldest quarter and gravel content (q=0.34),as well as between precipitation of coldest quarter and aspect (q=0.35). ConclusionThirteen cities,including Zhumadian and Nanyang in Henan,Huaihua,Shaoyang,and Zhangjiajie in Hunan,and Zunyi,Qiandongnan,and Tongren in Guizhou,were hot spots of total flavonoid glycosides in E.sagittatum.Precipitation,gravel content,temperature seasonality,and aspect significantly influence the accumulation of flavonoid glycosides in E.sagittatum.This study provides reference for the utilization and production zoning of E.sagittatum.
