AIM: To evaluate the long-term treatment outcomes in patients who underwent revision of external dacryocysto- rhinostomy (DCR) and nasal intubation by bicanalicular silicone tubing (BSTI) under endonasal endoscopic guidance. · METHODS: Data from 28 patients with recurrent dacryocystitis were retrospectively reviewed. Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance was performed in 28 eyes of 28 patients. The patients were evaluated with respect to the reason of recurrence, time to recurrence, time to revision, duration of follow-up and surgical success. · RESULTS: Endoscopic endonasal examination detected an osteotomy-side obstruction by the excessive granulation tissue in 24 patients (86%), nasal septal deviation in three patients (10%) and nasal polyp in one patient (4%). Recurrence occurred after a mean duration of 5.3±3.7 months following the first operation. The mean time between the first DCR operation and the revision DCR was 11.5 ± 9.3 months. After a mean follow-up of 14.9±7.8 months, the rate of anatomic success alone was 85% (24/28); the rate of subjective success was 78% (22/28). · CONCLUSION: Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance can be recommended in patients with recurrent dacryocystitis as a surgical approach that achieves satisfactory objective and subjective success rates.

The SgN VIgS Tool： User-Friendly Software to Design Virus-Induced gene Silencing （VIgS） Constructs for Functional genomics

Dear Editor,Virus-induced gene silencing （VIgS） is a fast and powerful method to study gene function in plants （Burch-Smith et al., 2004）. It is based on plant defense mechanisms against viral gene replication and allows high-throughput silencing of genes of inter- est （SenthiI-Kumar and Mysore, 2014）. The molecular mechanisms involved in post-transcriptional gene silencing （PTgS） have been studied intensively, and its steps are well known. The silencing pro- cess begins with the recognition through Dicer-like ribonucleases （DCL） of double-stranded RNA （dsRNA） that is generated during viral replication. Upon recognition, the dsRNA is processed into 21-24 nucleotide fragments, termed small interfering RNA （siRNA）. Based on sequence homology, both viral siRNA and plant mRNA associate with an RNA-induced silencing complex （RISC） and are targeted for degradation （Llave, 2010）.

Safety and Efficacy of Endoscopic Retrograde Cholangiopancreatography for Common Bile Duct Stones in Liver Cirrhotic Patients

作者：李德民赵洁赵秋覃华王波李荣香张敏g 胡继芬杨敏 Department of gastroenterology Tongji Hospital Tongji Medical College Huazhong University of Science and Technology Nursing Department Tongji Hospital Tongji Medical College Huazhong University of Science and Technology

In order to investigate the safety and efficacy of endoscopic retrograde cholangiopancreatograpy（ERCP） in liver cirrhosis patients with common bile duct stones, we retrospectively analyzed data of 46 common bile duct stones patients with liver cirrhosis who underwent ERCP between 2000 and 2008. There were 12 cases of Child-Pugh A, 26 cases of Child-Pugh B, and 8 cases of Child-Pugh C. 100 common bile duct stones patients without liver cirrhosis were randomly selected. All the patients were subjected to ERCP for biliary stones extraction. The rates of bile duct clearance and complications were compared between cirrhotic and non-cirrhotic patients. The success rate of selective biliary cannulation was 95.6% in liver cirrhotic patients versus 97% in non-cirrhotic patients（P〉0.05）. The bile duct clearance rate was 87% in cirrhotic patients versus 96% in non-cirrhotic patients, but the difference was not statistically significant. Two liver cirrhotic patients（4.35%, 2/46） who were scored Child-Pugh C had hematemesis and melena 24 h after ERCP. The hemorrhage rate after ERCP in non-cirrhotic patients was 3%. The hemorrhage rate associated with ERCP in Child-Pugh C patients was significantly higher（25%, 2/8） than that（3%, 3/100） in non-cirrhotic patients（P〈0.01%）. There was no significant difference between these two groups in the rate of post-ERCP pancreatitis（PEP） and cholangitis. ERCP is safe and effective for Child-Pugh A and B cirrhotic patients with common bile duct stones. Hemorrhage risk in ERCP is higher in Child-Pugh C patients.

基于最新的文献数据,我们研究了八面体配位下Ni^(2+)离子自旋禁止跃迁3A_(2)⁃1E的能量与新的电子云膨胀效应参数β1=(B B0)^(2)+(C C0)^(2)之间的经验关系,其中(B、C)和(B0、C0)分别是Ni^(2+)离子在晶体中和自由离子状态下描述3d电子间库仑作用的拉卡参数。研究结果表明,Ni^(2+)离子1E态的能量是β_(1)参数的线性函数。这样的发现确认了完全处理电子云膨胀效应需要同时考虑两个拉卡参数B和C约减贡献的重要事实。通常使用的电子云膨胀效应参数β=B B_(0)由于完全忽略了拉卡参数C的约减贡献,在估计1E态能级位置上是不准确的。相比而言,我们构建的理论方法则更好。本文所收集的实验数据以及实施的理论分析均将会对Ni^(2+)离子掺杂材料的光谱学研究有一定的参考价值。

新冠疫情暴发后,如何应对呼吸道传染病的传播这一难题再次摆在了人们面前.通风是最重要的工程防疫措施,ASHRAE、REHVA、SHASE以及中国的相关机构、学会就如何利用暖通空调系统有效防控COVID-19的传播相继出台了指导性文件.总结和分析系列指导性文件中有关通风量和气流组织方面的内容,发现现有工程防疫措施尚存在诸多需改进之处.传统的全空间通风在疫情期间表现出通风量不足、对近距离短期暴露事件效率低下、能耗高等缺陷,而基于先进气流组织的源头控制技术具有控制效率高、个性化可调、响应快速且节能潜力大等优势,恰好可弥补全空间通风的不足.在此基础上,系统地总结了基于先进气流组织的源头控制措施在呼吸道传染病传播控制方面的技术类型,并考虑到后疫情时代通风系统设计面临以“平疫结合”为导向的发展趋势,探讨了在“平疫结合”中应用源头控制技术的优势,以及在一些高风险场景应用源头控制从而实现“平疫结合”的技术路线,并分析了为落实“平疫结合”设计理念所需进一步探索的技术方向.所做探索预期为后续指南的编撰提供参考,为未来防疫通风设计带来新思路和新启示.
