Hepatocellular carcinoma(HCC)is the third most common cause for cancer-related death worldwide,especially in China[1].Hepatectomy is considered one of the most potentially curative therapies for HCC[2].As HCC is capable of vascular invasion and metastasis via the portal venous system,anatomical resection is often performed to reduce tumor *** process involves resecting the tumor-bearing portal branches and the corresponding hepatic parenchyma[3].Certain comparative studies have demonstrated better overall survival and disease-free survival with the use of anatomical resection when compared with nonanatomical resection[4–6].

Background： Several studies have reported that apolipoprotein A5 （APOA5） is involved in the development of non-alcoholic fatty liver disease （NAFLD）. However, no research has been performed regardingthe association between APOA5 polymorphisms and the risk of NAFLD. This study aimed to explore theassociation between APOA5 gene polymorphisms and NAFLD in a Chinese Han population.

为探讨肾上腺素能神经与脾功能联系,用免疫组织化学SP法和免疫荧光双标记法观察β_(2)-肾上腺素能受体(β_(2)-AR)和羊脾神经丝(NFs)在山羊脾中的表达分布特点。结果显示,β_(2)-AR免疫反应阳性产物在山羊脾中分布广泛,白髓、红髓、中央动脉、被膜、小梁、边缘区均有不同程度的着色,白髓中免疫组化染色阳性相对表达量极显著高于红髓(P<0.01),极极显著高于边缘区和被膜(P<0.001);红髓中免疫组化染色阳性相对表达量极显著高于边缘区和被膜(P<0.01);NFs免疫反应阳性产物在山羊脾中红髓、被膜、小梁、小血管、白髓和边缘区均有不同程度的着色,红髓中免疫组化染色阳性相对表达量显著高于白髓(P<0.05),极显著高于边缘区(P<0.01);被膜中免疫组化染色阳性相对表达量极显著高于边缘区和白髓(P<0.01)。共定位研究表明β_(2)-AR和NFs在3个区域存在共定位关系,在平滑肌细胞构成的被膜和小梁中存在,在富含平滑肌细胞的小血管(如中央动脉)中存在,在T、B淋巴细胞丰富区域(如白髓、红髓和边缘区)存在。表明交感-肾上腺素能神经系统对机体免疫具有调控作用。β_(2)-AR和NFs共定位结构证明脾受到交感-肾上腺素能神经的调控,交感神经纤维通过释放神经递质-去甲肾上腺素,作用于脾上的肾上腺素能受体实现功能调控。

The aim of this work was to assess the effect of applying three different doses of fluxapyroxad on microbial activity, community structure and functional diversity as measured by respiration, microbial biomass C, phospholipid fatty acid （PLFA） and community-level physiological profiles （CLPPs）. Our results demonstrated that substrate-induced respiration （on day 15） and microbial biomass C （on days 7 and 15） were inhibited by fiuxapyroxad, but stimulation was observed thereafter. In contrast, fluxapyroxad addition increased the basal respiration and metabolic quotients （qCO2） and respiratory quotients （QR）. Analysis of the PLFA profiles revealed that the total and bacterial biomass （both Gram-positive bacteria （GP） and Gram-negative bacteria （GN）） were decreased within the initial 15 days, whereas those as well as the GN/GP ratio were increased at days 30 and 60. Fluxapyroxad input decreased the fungi biomass but increased the bacteria/fungi ratio at all incubation time. Moreover, high fluxapyroxad input （75 mg fluxapyroxad kg-1 soil dry weight） increased the microbial stress level. A principal component analysis （PCA） of the PLFAs revealed that fluxapyroxad treatment significantly shifted the microbial community structure, but all of the observed effects were transient. Biolog results showed that average well color development （AWCD） and functional diversity index （H′） were increased only on day 60. In addition, the dissipation of fluxa- pyroxad was slow in soil, and the degradation half-lives varied from 158 to 385 days depending on the concentration tested.

Background Human amniotic epithelial cells （HAECs） are able to secrete biologically active neurotrophins such as brain-derived neurotrophic factor and neurotrophin-3, both of which exhibit trophic activities on dopamine neurons. Previous study showed that when human amniotic epithelial cells were transplanted into the striatum of 6-hydroxydopamine （6-OHDA）-induced Parkinson disease rats, the cells could survive and exert functional effects. The purpose of this study was to investigate the survival and the differentiation of human amniotic epithelial cells after being transplanted into the lateral ventricle of Parkinson＇s disease （PD） rats, and to investigate the effects of grafts on healing PD in models. Methods The Parkinson＇s model was made with stereotactic microinjection of 6-hydroxydopamine （6-OHDA） into the striatum of a rat. The PD models were divided into two groups： the HAECs group and the normal saline （NS） group. Some untreated rats were taken as the control. The rotational asymmetry induced by apomorphine of the HAECs group and the NS group were measured post cell transplantation. The expression of nestin and vimentin in grafts were determined by immunohistology. Ten weeks after transplantation the density of tyrosine hydroxylase positive cells in the substantia nigra of the HAECs group, NS group and the untreated group was determined. The differentiation of grafts was determined by TH immunohistology. High performance liquid chromatography （HPLC） was used to determine monoamine neurotransmitter levels in the striatum. Results The rotational asymmetry induced by apomorphine of the HAECs group was ameliorated significantly compared to the NS group two weeks after transplantation （P 〈0.01）. The grafts expressed nestin and vimentin five weeks after transplantation. TH immunohistochemistry indicated that the TH positive cells in the substantia nigra of the HAECs group increased significantly compared to the NS group （P 〈0.01）. Tyrosine hydroxylase （TH） posit
