The inventory of b.nthic macroinverteb.ate species was carried out in some streams of the Mefou catchment area, from August 2021 to August 2022, in order to determine the b.ological groups that make up the population and characterise these environments. The dataset acquired during this study made it possib.e to update the existing datab.se and contrib.te to the knowledge of the b.ological groups associated in these environments, and to provide additional information on the existing ones in relation to b.oindication. Overall 80 families were identified and, on the b.sis of frequencies of occurrence greater than 75%, 22 families were retained as potential b.ological indicators. The remarkab.e diversity of insects and the low ab.ndance of Diptera reflect the low degradation of environments and the good quality of water. The high diversity indices ob.ained reflect the maintenance of the favourab.e ecological conditions that favours the development of a b.lanced and, integrated b.ological community capab.e of adapting to changes.

Three new cyanido-b.idged heterometallic ReIVNin and ReIVCu one-dimensional systems were synthesized and extensively characterized b.th structurally and magnetically. Single-crystal X-ray diffraction analysis revealed that these compounds display a common topology, with chains composed of alternating [RetVc14（CN）2]2- and [Mn（cyclam）]2＋（M = Ni in 1, Cu in 2） or [Cull（N,N＇-dimethylcyclam）]2＋（in 3） b.ilding units. Two different chain orientations with a tilt angle of ca. 51° to 55° are present in the crystal packing of these compounds. The magnetic susceptib.lity measurements suggest the presence of intrachain ferromagnetic interactions b.tween the S = 3/2 ReTM centers and the 3d metal ions： S = 1 Ni1I or S = 1/2 CuII. At low temperature, a three-dimensional ordered magnetic phase induced b. interchain antiferromagnetic interactions （antiferromagnetic for 1 and 2; canted antiferromagnetic for 3） is detected for the three compounds.

为探讨防治设施土壤次生盐渍化的措施,于发生次生盐渍化的大棚土壤内埋设埋深40cm,间距6m及埋深70cm,间距8m的塑料暗管,研究土壤电导率(EC)、饱和导水率、体积质量等基本理化性质的变化,分析暗管排水对次生盐渍化土壤改良及番茄产量的影响。结果表明:埋设暗管可以明显降低次生盐渍化土壤的EC值,尤其是暗管上方的EC值显著低于对照;同时,土壤饱和导水率增加,体积质量降低而总孔隙度升高;番茄平均单果质量增加,产量显著提高,各项指标均表现为埋深70cm,间距8m暗管的处理优于埋深40cm,间距6m的处理。埋深70cm,间距8m暗管的处理在大棚土壤次生盐渍化改良中的效果优于埋深40cm,间距6m的处理。

Hepatocellular carcinoma(HCC) is one of the most common causes of cancer-related death worldwide. Chronic infection of hepatitis b.virus(Hb.) and/or hepatitis C virus(HCV) is a major risk factor in the development of the HCC, independently from excessive alcohol ab.se and metab.lic disease. Since the b.ology of Hb. and HCV is different, their oncogenic effect may go through different mechanisms, direct and/or indirect. Viral hepatitis infection is associated with cellular inflammation, oxidative stress, DNA damage, that may lead to sub.equent hepatic injuries such as chronic hepatitis, fib.osis, cirrhosis, and finally HCC. Direct oncogenic properties of these viruses are related with their genotypic characteristics and the ab.lity of viral proteins to interact with host proteins, thus altering the molecular pathways b.lance of the cells. In addition, the integration of Hb. DNA, especially the gene S and X, in a particular site of the host genome can disrupt chromosomal stab.lity and may activate various oncogenic mechanisms, including those in hematopoietic cells. Recently, several studies also had demonstrated that viral hepatitis could trigger the population of hepatic cancer stem cells. This review summarize availab.e pre-clinical and clinical data in literature regarding oncogenic properties of Hb. and HCV in the early initiation of HCC.

目的探讨尿流动力学检查对脊髓脂肪瘤患儿的评估价值。方法回顾性分析上海新华医院小儿外科2010—2011年间16例脊髓脂肪瘤初次手术患儿的临床资料，对患儿术前及术后半年的临床症状、尿流动力学检查、影像学表现、术中分型及松解程度进行综合评估，比较各型患儿术后恢复情况。结果根据术中栓系松解程度分为可完全松解型（A组，10例）及不可完全松解型脊髓脂肪瘤（b.，6例）。术前无明显排尿功能异常者3例，所有患儿均有不同程度的尿流动力学结果异常。术后半年进行再评估时发现所有患儿经手术治疗后均基本能保持原有神经功能，其中临床症状改善率达43．8％（A组6例，b.1例），加重25．0％（A组1例，b.3例）。尿流动力学结果改善率62．5％（A组7例，b.3例），加重率25．0％（A组1例，b.3例）。结论脊髓脂肪瘤患儿常伴有不同程度的膀胱功能障碍，于术前行尿流动力学检查可以早期发现亚临床期膀胱功能障碍的患儿，从而帮助临床医师及时手术干预。术后定期行该检查能够帮助监测患儿术后排尿情况，必要时及时处理。尿流动力学检查对脊髓脂肪瘤患儿具有重要意义。
