    • 摘要: 非洲猪瘟是由非洲猪瘟病毒感染家猪和欧亚野猪引起的一种急性、出血性、高度接触性传染病,其表现特点是高热、多器官出血性病变,急性死亡,死亡率高达100%,严重威胁全球养猪业的健康稳定发展。目前尚未研制出有效的疫苗,其缘由除了与我们对该病毒了解不够全面以外,还与该病毒结构复杂、基因组庞大、能够编码调节宿主细胞功能、抑制免疫和免疫逃逸等相关的蛋白有关。本文旨在当前国内外的研究结果基础上,综述非洲猪瘟病毒几种重要蛋白的研究进展,以期为非洲猪瘟疫苗研发、新检测方法的探索提供一些借鉴。

    • 摘要: 目的:探讨转化生长因子诱导的基因蛋白与肿瘤耐药的相关性。方法:分别用载有 TGFBI 基因质粒以及空质粒转染人卵巢癌细胞株 SKOV3,采用 Western blot 技术检测转染后两组细胞 TGFBI 蛋白的表达情况,用 MTT 法检测不同浓度紫杉醇、顺铂对上述两组细胞的抑制率,采用流式细胞技术检测紫杉醇对上述两组细胞凋亡的影响。结果:用载有 TGFBI 基因质粒转染细胞后其 TGFBI 蛋白表达情况显著高于用空质粒转染细胞后 TGFBI 蛋白的表达。在紫杉醇、顺铂同种药物浓度下,TGFBI 转染后细胞抑制率显著高于空质粒转染细胞(P <0.05)。TGFBI 质粒转染细胞凋亡率为(67.35±12.36)%,而空质粒转染细胞凋亡率为(50.21±14.85)%,TGFBI 质粒转染细胞凋亡率显著高于空质粒转染细胞凋亡率(P <0.05)。结论:TGFBI 高表达能够降低人卵巢癌细胞 SKOV3的耐药性,提高肿瘤细胞对化疗药物的敏感性,有助于促进肿瘤细胞的凋亡。%Objective:To investigate the correlation of gene expression induced by transforming growth factor in tumor resistance. Methods:The expression of SKOV3 protein in human ovarian cancer cell line TGFBI was transfect-ed with gene plasmid and empty plasmid. The expression of TGFBI protein was detected by Western blot,and the inhi-bition rate was detected by MTT assay. The effect of paclitaxel on apoptosis of two cells was detected by flow cytome-try. Results:The expression of TGFBI protein was significantly higher than that of TGFBI protein after transfection of TGFBI gene. The inhibition rate of TGFBI was significantly higher than that of empty plasmid transfected cells(P <0. 05)at the same concentration of paclitaxel and cisplatin. The apoptosis rate of TGFBI plasmid was(67. 35 ± 12. 36)% ,and the apoptosis rate of empty plasmid was(50. 21 ± 14. 85)% . The apoptosis rate of TGFBI cells was significantly higher than that of empty plasmid transfected cells(P < 0. 05). Conclusion:High expression of TGFBI can reduce the drug resistance of ovarian cancer cell line SKOV3,improve the sensitivity of tumor cells to chemothera-peutic drugs,and can promote tumor cell apoptosis.
    • 摘要: 据韩媒报道,韩国食品研究院通过动物实验研究发现:桑属植物的根皮桑白皮提取物可有效缓解压力。研究小组为确认可食用天然提取物对压力的缓解效果,开发了可定量测定、评估白鼠压力指数的超声波检测技术,通过该技术确定了桑白皮提取物有缓解压力的效果。摄取桑白皮提取物的白鼠在压力下,与对照相比,随着摄取时间与浓度变化,压力最高减少了50%。

    • 摘要: Objective To study the rules of the expression of oncogene APC, Bcl-2, K-ras, Ki-67 and Cox-2 and their roles in the course of occurrence and development in melanosis coli(MC) and colorectal carcinoma and its precancerous lesion,and to explore MC relation to assess their risks of cancer. Methods All of 445 patients selected by colonoscopy, histopathology and special staining confirmed were divided into five groups. Immunohistochemistry method was used to examine the expression of APC, Bcl-2, K-ras, Ki-67 and Cox-2 in MC 108 cases, ulcerative colitis (UC) 69 cases, colorectal polyps(CP) 122 cases, colorectal carcinoma (CRC) 96 cases and 50 subjects of normal colorectal mucosa. Results The positive expression rate of Bcl-2,K-ras of the older MC group 51. 4 % (36/70) ,41. 4% (29/70) was significantly higher than that of young and middle-aged MC group 26. 3% (10/38) , 21. 1% (8/38) ( P 0. 05). Conclusion Apoptosis and mutation of cell mucosal are related to elderly patients with MC, the patients with MC compared with those of normal mucosa, ulcerative colitis and colorectal polyps, the cells mucosal apoptosis and mutation of MC are possible between normal mucosa and precancerous lesions. For the patients with MC and polyps,the active colonoscopy,histopathology and immunohistochemical examination should be carried on as early as possible. Periodical follow-up is necessary,the controlling strategies of MC is practical and can improve level of the diagnosis and treatment of early colorectal carcinoma in primary hospital.%目的 研究结肠黑变病(MC)黏膜组织大肠癌相关癌基因(APC、Bcl-2、K-ras、Ki-67)和环氧化酶2(Cox-2)表达的变化,与结肠癌、癌前病变之间的比较,探讨 MC病变癌变的风险.方法 本研究纳入445例患者,根据肠镜检查和病理结果分为5组.MC组108例,对照组分为4组:溃疡性结肠炎(UC)组69例,大肠息肉(CP)组122例,大肠癌(CRC)组96例,正常黏膜组50例.均行黏膜组织相关癌基因(APC、Bcl-2、K-ras、Ki-67) 和Cox-2的免疫组化检测.结果 Bcl、K-ras阳性表达率,MC老年组51.4%(36/70)、41.4%(29/70)显著高于MC中青年组26.3%(10/38)、21.1%(8/38)(P0.05).结论 MC老年病人与中青年相比,细胞黏膜凋亡与突变相关性大;MC与正常黏膜、UC、CP比较,MC细胞黏膜凋亡与突变可能性介于正常黏膜与癌前病变之间.为此,临床应重视MC,尤其MC 伴息肉,通过肠镜下活检行黏膜组织大肠癌相关癌基因监测,可提高基层医院早期大肠癌的诊治水平,可作为切实可行的MC防治策略.

    • 摘要: WH EN Beijing resident Xie Hongzhen visits her rural hometown in jiangsu Province every year,the top item on her list of things to take back to Beijing with her is cooking oil.as many bottles as she can carry."It’s safe for me to eat oil made from soybeans grown by my parents in my hometown."said Xie."I don’t trust the soybean oil sold in the supermarkets in Beijing as it is mainly made from genetically modified(GM)soybeans."The jury is still out on the safety of GM crops,and public debate on the topic has flourished in China."

    • 摘要: 流感病毒经过遗传漂变会周期性地变得更具毒性,严重威胁全球公共健康。通常,抵抗新流感菌株的疫苗需要数月的时间完成开发、测试和生产等环节,同时它们对已患流感者毫无作用。因此,当致命性流感突然出现和快速传播时,疫苗的研制和发送所造成的长时间延误让人们束手无策,而人们缺乏免疫能力又加速了流感病毒在公众间的传播。
