用PCR技术同时检测微量血痕的种属来源及其DNA多态性 [PDF]
Zhongshan Daxue xuebao. Yixue kexue ban, 1992 应用聚合酶链反应技术扩增血痕DNA,根据扩增产物中有无aPoB基因的数量可变重复序列(VNTR)及其扩增片段的大小即可同时确定其种属特异性和DNA的多态性。实验结果显示人血痕可见扩增带并具有多态性,而猴猪狗猫鸡血痕无扩增带。

PCR/异源双链形成分析法在β地中海贫血产前诊断中的应用 [PDF]
Zhongshan Daxue xuebao. Yixue kexue ban, 1993 采用聚合酶链反应(PCR)结合聚丙烯酰胺凝胶电泳(PAGE),检测PCR产物异源双链形成情况,诊断和产前诊断B珠蛋白生成障碍性贫血(β地中海贫血)CD41-42(-CTTT)突变。此方法简便快速,可区分有无突变,并能鉴别纯合子与杂合子。应用本方法进行了4例产前诊断。对此方法的优点和局限性及应用前景进行了讨论。

SARS‐CoV‐2 infection as cause of in‐utero fetal death: regional multicenter cohort study
Ultrasound in Obstetrics &Gynecology, Volume 62, Issue 6, Page 867-874, December 2023., 2023 ABSTRACT Objective Placental infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can lead to placental insufficiency and in‐utero fetal death (IUFD). The objective of this study was to confirm and quantify the extent to which fetoplacental infection with SARS‐CoV‐2 is a cause of fetal death.

Journal of Advanced Nursing, Volume 76, Issue 8, Page 2191-2197, August 2020., 2020 Abstract Aim To determine the effectiveness of a hydrophobic dressing (Cutimed Sorbact®) against a silver dressing (Aquacel® Ag Extra) in the level of colonization of chronic venous leg ulcers. The secondary endpoints are health‐related quality of life, level of pain, and time to complete healing.

Study on the mechanisms of Pygopus-2 promoting invasion and metastasis in hepatocellular carcinoma [PDF]
, 2016 第一部分Pygopus-2在HCC中高表达与病人恶性预后密切相关 Pygopus-2是经典Wnt/β-Catenin信号通路转录复合体的重要成分。本研究目的是观察在原发性肝癌中Pygopus-2的表达情况及相关的临床病理意义。RT-PCR的方法检测50对肝癌病人组织标本中癌组织与癌旁组织中Pygopus-2的mRNA表达情况，结果发现癌组织中Pygopus-2的mRNA水平明显高于癌旁组织(P=0.009)。免疫组化分析显示异常表达的Pygopus-2蛋白与肝癌病人的年龄(P=0.025)、肿瘤大小(P=

Amplification of Ovis aries papillomavirus type 2 DNA from an ovine cutaneous fibropapilloma
Veterinary Dermatology, Volume 35, Issue 2, Page 226-229, April 2024.Seven of 60 Perendale sheep within a flock developed single or multiple exophytic masses on their distal hind limbs. A mass was excised from one sheep and histological evaluation revealed epidermal and mesenchymal proliferation, papillomavirus‐induced keratinocyte changes and marked keratohyalin clumping.
