颅脑损伤部位及程度与日常生活活动能力的相关性

目的：研究颅脑损伤部位及程度与日常生活活动能力的相关性,为提高鉴定意见的准确性提供理论依据。方法选取颅脑损伤被鉴定人501例,详细记录其伤前情况、损伤部位及程度、治疗方式、教育程度,应用日常生活活动能力量表（Barthel指数）对被鉴定人进行测验,统计损伤部位及程度与Barthel指数的相关性。结果轻度颅脑损伤组各损伤部位Barthel指数差异无统计学意义（P〉0.05）;中度颅脑损伤组蛛网膜下腔出血与其他脑叶损伤,顶、枕叶损伤与额叶损伤,顶、枕叶损伤与颞叶损伤间Barthel指数差异均具有统计学意义（P〈0.05）,额叶损伤与颞叶损伤Barthel指数差异无统计学意义（P〉0.05）;重度颅脑损伤不论手术与否,各颅脑损伤部位的Barthel指数两两之间差异均有统计学意义（P〈0.05）。结论颅脑损伤部位与Barthel指数存在一定相关性,对分析判断颅脑损伤后日常生活活动能力具有重要的参考价值。

羊口疮病毒F1L与B2L基因核酸疫苗联合免疫小鼠特性的研究

为评价羊口疮病毒(OrfV)F1L与B2L基因核酸疫苗PVAX1-F1L、PVAX1-B2L联合免疫小鼠诱导体液和细胞免疫的应答效果,分别将PVAX1-F1L+PVAX1-B2L、PVAX1-B2L、PVAX1-F1L、PVAX1空载体与PBS通过后腿肌肉注射方式免疫小鼠,采用ELISA方法检测免疫不同时间段的小鼠血清中OrfV特异性抗体及细胞因子IL-2、IL-4和IFN-γ,并通过MTT法检测免疫小鼠脾淋巴细胞增殖反应。结果显示,PVAX1-F1L+PVAX1-B2L联合免疫组小鼠血清抗体效价及IL-2、IFN-γ细胞因子水平显著(P<0.05)高于PVAX1-F1L和PVAX1-B2L单独免疫组,IL-4细胞因子水平差异不明显,但均与PVAX1空载体和PBS组差异极显著(P<0.01);PVAX1-F1L+PVAX1-B2L联合免疫组小鼠脾淋巴细胞增殖水平与PVAX1-F1L和PVAX1-B2L单独免疫组相比,差异显著(P<0.05),与PVAX1空载体和PBS组相比,差异极显著(P<0.01)。结果表明,PVAX1-F1L+PVAX1-B2L联合免疫小鼠能够增强OrfV特异性抗体的分泌和细胞免疫应答,这为羊口疮新型疫苗的研制奠定了理论基础。     

Association of autoimmune type atrophic corpus gastritis with Helicobacter pylori infection

AIM:To study the association between Helicobacter pylori(H.pylori)infection and autoimmune type atrophic gastritis. METHODS:Twenty-three patients with different grades of atrophic gastritis were analysed using enzyme immunoassay-based serology,immunoblot-based serology,and histology to reveal a past or a present H.pylori infection.In addition,serum markers for gastric atrophy(pepsinogenⅠ,pepsinogenⅠ/Ⅱand gastrin)and autoimmunity[parietal cell antibodies(PCA), and intrinsic factor(IF),antibodies]were determi...

Distribution of Chemical Phenotypes (Chemotypes) in European Agricultural Hemp (Cannabis sativa L.) Cultivars

In Europe, more than 50 approved cultivars of fiber hemp (Cannabis sativa L.) are in agricultural production. Their content of psychoactive tetrahydrocannabinol (THC) is legally restricted to <0.2% (%w/w in the dry, mature inflorescences). Cannabis strains with much higher THC contents are also grown, illegally or under license for drug production. Differentiation between these two groups relies on biochemical quantification of cannabinoid contents in mature floral material. For nonflowering material or tissue devoid of cannabinoids, the genetic prediction of the chemical phenotype (chemotype) provides a suitable method of distinction. Three discrete chemotypes, depending on the ratio of THC and the noneuphoric cannabidiol (CBD), can be distinguished: a “THC-predominant” type, a “CBD-predominant” type, and an intermediate chemotype. We present a systematic genetic prediction of chemotypes of 62 agricultural hemp cultivars grown in Europe. The survey reveals the presence of up to 35% B_T allele-carrying individuals (representing either a THC-predominant or an intermediate chemotype) in some cultivars—which is unexpected considering the legal THC limit of 0.2% THC. The fact that 100% of the seized drug-type seeds in this study revealed at least one B_T allele, reflects that plant breeding efforts have resulted in a fixation of the B_T allele in recreational Cannabis. To guarantee a sincere forensic application based on a genetic chemotype prediction, we recommend not to classify material of unknown origin if the samples size is below nine genetically independent individuals.     

Guest workers or unauthorized immigrants? The case of forest workers in the United States

This study examines regional differences in the legal status of forest workers in the Pacific Northwest and Southeastern United States, using United States Department of Labor data and qualitative fieldwork in Alabama and Oregon. The authors find that there are significantly fewer H-2B guest workers on federal lands in Oregon than on privately owned forest plantations in Alabama, and the Southeast more generally. By contrast, numerous workers on federal lands in Oregon are undocumented. This difference may largely be explained by variations in the economies of scale in forest work in the Pacific Northwest (federal lands) and the Southeast (mainly private lands). The study also finds that there is no real difference in the working conditions of undocumented immigrants and guest workers—both groups face labor exploitation. Guest workers in the forest industry, many of whom have no previous work experience or access to social networks in the United States, face extreme isolation at worksites, are beholden to contractors, fear losing their jobs if they complain, and are generally unaware of their basic rights. By contrast, many undocumented forest workers in Oregon belong to established social networks through which they are recruited onto forest labor crews. However, unauthorized workers are also vulnerable to labor exploitation because they fear deportation and are obliged to their kin-employers. Policy recommendations to improve labor conditions and enforce existing labor laws for all forest workers include: better tracking of workers across states to monitor labor abuses, allocating more resources to state labor departments to facilitate worker outreach and worksite inspections, and better communication among land management officials and the Department of Labor.
