人乳头瘤病毒感染的局部免疫反应

本文应用ABC法对30例尖锐湿疣(CA)和30例宫颈癌(CCU)进行原位观察,分析对比两者浸润单一核细胞(MNC)的亚群组成、分布及活化状态。结果提示,两者局部免疫均受抑制,而以宫颈癌为甚。依此本文对不同类型HPV相关疾病的局部免疫反应状态及宿主对不同型别HPV感染的免疫反应进行探讨。     

Mononuclear-cell subsets in human idiopathic crescentic glomerulonephritis (ICGN): Analysis in tissue sections with monoclonal antibodies

Mononuclear inflammatory cells (MIC) were analyzed in renal biopsies from 16 patients with ICGN (7 with glomerular immune complex deposits, 3 with anti-GBM disease, and 6 without immune deposits) by the avidin-biotin-immunoperoxidase technique utilizing monoclonal antibodies to cell surface antigens: T11 (total T), T4 (inducer/helper T), T8 (suppressor/cytotoxic T), B1 (B cells), M1 (monocytes/granulocytes), and Leu 7 [natural killer (NK) cells]. Total MIC were significantly increased in both glomeruli and interstitial tissues of the patients. Interstitial MIC consisted mainly of lymphocytes (80%) and monocytes (19%), with small numbers of B and NK cells present. In contrast, MIC in renal glomeruli of patients with ICGN were composed of monocytes (65%) rather than T lymphocytes (34%). A majority of T lymphocytes found in renal tissues of patients and controls had the helper/inducer phenotype. Tissue T4/T8 ratios were not significantly different in the glomeruli and interstitium. Monocytes and T lymphocytes accumulating in renal tissues of patients with ICGN may mediate glomerular injury in all forms of human ICGN.Presented in part at the 15th Annual Meeting of the American Society of Nephrology, Chicago, Illinois, 1982.     

致癌物分子结构识别中的一种特征提取方法

本文论述基于拓扑参数的致癌物分子结构识别中的一种特征参数－－特征片段的提取方法；对一组活性已知的分子训练集，将其分子结构用ＫＬＮ编码法进行编码并输入计算机，在三个约束条件下用深度第一法对各分子进行结构分解，生成片段文件，并汇总成片段总库，然后用统计检验和聚类分析提取和优化特征片段，从而为识别模型提供合理有效的特征参数。     

带臂外侧上皮神经及其营养血管筋膜皮瓣的应用解剖

目的:为带臂外侧上皮神经及其营养血管筋膜皮瓣提供解剖学基础.方法:32例经灌注红色乳胶的成人上肢标本,对臂外侧上皮神经及其营养血管等进行了较详细的应用解剖学研究.结果:臂外侧上皮神经在均由腑神经发出,起点横径为1.5±0.4mm,在三角肌深方斜向外下3.6±1.1cm从该肌后缘中1/3浅出肌间隔,分为上支和下支,分布于三角肌后部、外侧部和臂外侧上部.该神经的营养血管起源于旋肱后动脉,起点外径为0.9±0.4mm;其行程、分支和分布均同在神经,供血范因为14.8×9.8cm~2,并与周围的皮动脉存在丰富吻合.结论:带臂外侧上皮神经及其营养血管筋膜皮 瓣可视受区需要设计成游离瓣或旋转瓣,用于修复邻近部位、手或颌面部缺损.     

用液晶开关实现RDS立体成像的方法学研究

本文报道以ＲＤＳ立体图作为检测图形，用液晶开关实现其三维立体显示的一些探索性研究，用液晶开关眼镜作为立体图的同步分离部件。使得本系统建立于继时法成像的基础上，因而消除了“红绿竞争”等影响检出精度的因素；系统采用帧频作为同步切换的总控信号，使ＣＲＴ的视页切换与液晶眼镜开关同步，为此而开发出的显示寄存器编程技术解决了ＣＲＴ视页切换的超高速要求。     

19种变应原在门诊变应性疾病病人中的分布情况研究

目的探讨门诊变应性疾病病人中变应原的分布情况,寻找变应性疾病的诱发因素,为预防和减少变应性疾病的发作提供依据。方法对1115例变应性疾病病人进行19种变应原疫苗检测,对其中1030例阳性资料,进行归类、整理及统计分析。结果城镇组以尘螨、桑蚕丝变应原占的比重较大,而多价兽毛、多价昆虫、多价霉菌Ⅰ组等仅次之;乡村组以多价霉菌Ⅰ组、屋尘、多价昆虫、多价兽毛、多价羽毛、春季花粉Ⅲ组、夏秋花粉变应原占的比重较大,而尘螨、桑蚕丝等次之。两组间差异有极显著性(X2=6099.05,r=0.96,t=118.88,P<0.001)。结论诱发变应性疾病的变应原谱与病人的年龄、性别、居住区域有关。

Porcine germline genome engineering

Germline editing, the process by which the genome of an individual is edited in such a way that the change is heritable, has been applied to a wide variety of animals [D. A. Sorrell, A. F. Kolb, Biotechnol. Adv. 23, 431–469 (2005); D. Baltimore et al., Science 348, 36–38 (2015)]. Because of its relevancy in agricultural and biomedical research, the pig genome has been extensively modified using a multitude of technologies [K. Lee, K. Farrell, K. Uh, Reprod. Fertil. Dev. 32, 40–49 (2019); C. Proudfoot, S. Lillico, C. Tait-Burkard, Anim. Front. 9, 6–12 (2019)]. In this perspective, we will focus on using pigs as the model system to review the current methodologies, applications, and challenges of mammalian germline genome editing. We will also discuss the broad implications of animal germline editing and its clinical potential.
