采用不同剂量尿激酶治疗急性心肌梗死的对比研究

目的　评价不同剂量国产尿激酶静脉溶栓治疗急性心肌梗死 (AMI)的疗效。方法　随机抽取住院AMI患者分成两组 ,分别给予常规剂量 (12 0～ 15 0万U)和大剂量 (2 0 0～ 30 0万U)尿激酶静脉溶栓治疗 ,观察其疗效。结果　常规剂量组再通率 (5 5 5 6 % ) <大剂量组 (76 47% ) ,P <0 0 5 ;常规剂量组出血率 (5 5 6 % ) <大剂量组 (17 6 5 % ) ,P <0 0 5 ;常规剂量组 4周内病死率 (5 5 6 % ) <大剂量组 (5 88% ) ,P >0 0 5。结论　尿激酶静脉溶栓治疗AMI ,剂量增大再通率就增大 ,但出血等并发症亦增加 ,总死亡率并未降低。因此主张应用 12 0～ 15 0万U为宜。

囊肿切除治疗婴儿先天性胆总管囊肿

目的探讨囊肿切除、胆道重建治疗婴儿胆总管囊肿的疗效.方法1984年6月～1999年6月共有15例婴儿先天性胆总管囊肿患儿在我科接受了囊肿切除、胆道重建手术治疗,并对这些患儿进行了随访,随访资料包括症状、体征、B超.钡餐及肝功能检查.结果随访资料完整者12例,除1例术后3个月死于肝功能衰竭外,其余11例成活的患儿生长发育均正常;2例未行套叠瓣的患儿偶有上腹疼痛,但腹痛可自行缓解,钡餐检查见钡剂返流;全组病例肝功均正常,未见胆道结石、消化道溃疡、食道下端静脉曲张.结论囊肿切除、胆道重建治疗婴儿先天性胆总管囊肿可取得满意的疗效.     

五种生长因子mRNA在兔角膜中的表达

目的 了解ＥＧＦ、ＴＧＦ－α、ｂＦＧＦ、ＴＧＦ－β１和ＰＤＧＦ在兔角膜上皮和基质中的表达情况,探讨其在角膜伤口愈合中的作用。方法 应用原位核酸分子杂交方法检测兔角膜上皮和基质中ＥＧＦ、ＴＧＦ－α、ｂＦＧＦ、ＴＧＦ－β１和ＰＤＧＦ ｍＲＮＡＲ的表达。结果 ＥＧＦ、ＴＧＦ－α和ＰＤＧＦ ｍＲＮＡ仅在正常角膜上此细胞层表达,基质中未见表达;ｂＦＧＦ和ＴＧＦ－β１ ｍＲＮＡ在正常角膜伤口和基质中均有表达。     

Characterization and phylogenetic analysis of a neurovirulent Zika virus isolated from Cambodia in 2019

The geographic range of Zika virus (ZIKV) has expanded from Asia to the Americas, leading to the 2015–2016 pandemic with enhanced neurovirulence. At present, ZIKV is continuously circulating in many Southeast Asian countries. Unfortunately, the persistent evolution of ZIKV in Southeast Asia and its influence on the biological characteristics of the virus remain incompletely understood. In this study, the in vitro and in vivo properties of a new ZIKV isolate obtained from Cambodia in 2019 (CAM/2019) were characterized and compared with those of the Cambodian strain (CAM/2010). Compared with CAM/2010, the CAM/2019 virus showed similar plaque morphology and growth curves in cell cultures and induced comparable viremia and organ viral loads profiles in both BALB/c and A129 (IFNAR1^−/−) mice upon intraperitoneal (i.p.) inoculation. Remarkably, the CAM/2019 virus exhibited enhanced neurovirulence in neonatal mice compared with CAM/2010, with a 74-fold reduction in the 50% lethal dose (LD₅₀). Consistently, CAM/2019 produced higher viral loads in the brains of BALB/c neonatal mice than CAM/2010 did. Sequence alignment showed that the CAM/2019 virus has acquired 12 amino acid substitutions, several of which were found to be associated with neurovirulence. In particular, the CAM/2019 virus shared an A1204T substitution in NS2A with the Thai isolate SI-BKK02 that was isolated from a microcephaly case. Taken together, our results indicate that a ZIKV strain isolated with specific mutations has emerged in Cambodia, highlighting the need for extensive molecular and disease surveillance in Cambodia and other Asian countries.
