1眼前节内眼手术应用5%吡咯烷酮碘两种不同用法的前瞻性随机化比较研究显示文摘目的:确定5%吡咯烷酮碘采用两种不同的方法(结膜囊滴两滴和10ml溶液穹窿结膜冲洗)对降低结膜囊菌群的功效。方法:在这项前瞻性对照实验中。将行眼前节手术的200只眼随机分为对照组和研究组。两组病例术前均给予氧氟沙星滴眼液局部点眼和5%吡咯烷酮碘眶周区域皮肤擦洗消毒。术前对照组眼结膜囊内给予2滴5%吡咯烷酮碘溶液,研究组眼用5%吡咯烷酮碘溶液冲洗穹窿结膜。分别于术前和术后4个时间点行结膜细菌培养。结果:研究组78只眼中20只眼(26%)术前结膜细菌培养阳性:对照组94只眼中40只眼(43%)为阳性(P=0.02)。手术结束时。研究组78只眼中14只眼(18%)、对照组94只眼中30只眼(32%)结膜细菌培养阳性(PP=0.05)。结论:手术时应用5%吡咯烷酮碘溶液冲洗穹窿结膜与结膜囊仅点入两滴相比。前者显著降低了结膜细菌培养阳性率。Herminia Mino de Kaspar Robert T.

2Human adenovirus(HAdV)infection in children with acute respiratory tract infections in Guangzhou,China,2010–2021:a molecular epidemiology study显示文摘Background Human adenovirus(HAdV)infection can cause a variety of diseases.It is a major pathogen of pediatric acute respiratory tract infections(ARIs)and can be life-threatening in younger children.We described the epidemiology and subtypes shifting of HAdV among children with ARI in Guangzhou,China.Methods We conducted a retrospective study of 161,079 children diagnosed with acute respiratory illness at the Guangzhou Women and Children’s Medical Center between 2010 and 2021.HAdV specimens were detected by real-time PCR and the hexon gene was used for phylogenetic analysis.Results Before the COVID-19 outbreak in Guangzhou,the annual frequency of adenovirus infection detected during this period ranged from 3.92%to 13.58%,with an epidemic peak every four to fve years.HAdV demonstrated a clear seasonal distribution,with the lowest positivity in March and peaking during summer(July or August)every year.A signifcant increase in HAdV cases was recorded for 2018 and 2019,which coincided with a shift in the dominant HAdV subtype from HAdV-3 to HAdV-7.The latter was associated with a more severe disease compared to HAdV-3.The average mortality proportion for children infected with HAdV from 2016 to 2019 was 0.38%but increased to 20%in severe cases.After COVID-19 emerged,HAdV cases dropped to 2.68%,suggesting that non-pharmaceutical interventions probably reduced the transmission of HAdV in the community.Conclusion Our study provides the foundation for the understanding of the epidemiology of HAdV and its associated risks in children in Southern China.Yi Chen Tao Lin Chang‑Bing Wang Wan‑Li Liang Guang‑Wan Lian Mark Zanin Sook‑San Wong Xin‑Gui Tian Jia‑Yu Zhong Ying‑Ying Zhang Jia‑Hui Xie Ling‑Ling Zheng Fei‑Yan Chen Run Dang Ming‑Qi Zhao Yi‑Yu Yang Rong Zhou Bing Zhu 2022World Journal of Pediatrics2022,18,8:5

7Endoscopic submucosal dissection vs endoscopic mucosal resection for colorectal polyps:A meta-analysis and metaregression with single arm analysis显示文摘BACKGROUND Endoscopic submucosal dissection(ESD)has shown to be effective in management of colorectal neoplasm in the Asian countries,while its implementation in Western countries where endoscopic mucosal resection(EMR)is preferred is still debatable.AIM To compare the surgical,histological,and oncological outcomes between ESD and EMR in the treatment of colorectal polyps,with subgroup analysis comparing the efficacy of ESD and EMR between Japan and the rest of the world.METHODS Embase and Medline databases were searched from inception to October 2020 in accordance with PRISMA guidelines for studies comparing en bloc,complete resection,margin involvement,resection time,need for additional surgery,complications,and recurrence rate of ESD with EMR.RESULTS Of 281344 colorectal polyps from 21 studies were included.When compared to EMR,the pooled analysis revealed ESD was associated with higher en bloc and complete resection rate,and lower lateral margin involvement and recurrence.ESD led to increased procedural time,need for additional surgery,and perforation risk.No significant difference in bleeding risk was found between the two groups.Meta-regression analysis suggested only right colonic polyps correlated with an increased perforation risk in ESD.Confounders including polyp size and invasion depth did not significantly influence the en bloc and complete resection rate,bleeding risk and recurrence.In subgroup analysis,Japan performed better than the rest of the world in both ESD and EMR with perforation risk of 4%and 0.0002%,respectively,as compared to perforation risk of 8%and 1%,respectively,in reports coming from rest of the world.CONCLUSION ESD resulted in better resection outcomes and lower recurrence compared to EMR.With appropriate training,ESD is preferred over EMR as the first-line therapy for resection of colorectal polyps,without restricting to lesions greater than 20 mm and those with high suspicion of submucosal invasion.Xiong Chang Lim Kameswara Rishi Yeshayahu Nistala Cheng Han Ng Snow Yunni Lin Darren Jun Hao Tan Khek-Yu Ho Choon-Seng Chong Mark Muthiah 2021World Journal of Gastroenterology2021,27,25:4
8ICC density predicts bacterial overgrowth in a rat model of post-infectious IBS显示文摘AIM:To investigate the interstitial cells of Cajal(ICC) number using a new rat model.METHODS:Sprague-Dawley rats were assigned to two groups.The first group received gavage with Campylobacter jejuni(C.jejuni) 81-176.The second group was gavaged with placebo.Three months after clearance of Campylobacter from the stool,precise segments of duodenum,jejunum,and ileum were ligated in self-contained loops of bowel that were preserved in anaerobic bags.Deep muscular plexus ICC(DMP-ICC) were quantified by two blinded readers assessing the tissue in a random,coded order.The number of ICC per villus was compared among controls,Campylobacter recovered rats without small intestinal bacterial overgrowth(SIBO),and Campylobacter recovered rats with SIBO.RESULTS:Three months after recovery,27% of rats gavaged with C.jejuni had SIBO.The rats with SIBO had a lower number of DMP-ICC than controls in the jejunum and ileum.Additionally there appeared to be a density threshold of 0.12 DMP-ICC/villus that was associated with SIBO.If ileal density of DMP-ICC was < 0.12 ICC/villus,54% of rats had SIBO compared to 9% among ileal sections with > 0.12(P<0.05).If the density of ICC was < 0.12 DMP-ICC/villus in more than one location of the bowel,88% of these had SIBO compared to 6% in those who did not(P<0.001).CONCLUSION:In this post-infectious rat model,the development of SIBO appears to be associated with a reduction in DMP-ICC.Further study of this rat model might help understand the pathophysiology of postinfectious irritable bowel syndrome.Sam-Ryong Jee Walter Morales Kimberly Low Christopher Chang Amy Zhu Venkata Pokkunuri Soumya Chatterjee Edy Soffer Jeffrey L Conklin Mark Pimentel 2010World Journal of Gastroenterology2010,16,29:3

12手助式腹腔镜肾切除术围手术期并发症的处理显示文摘目的探讨手助式腹腔镜肾切除术围手术期并发症的处理方法。方法回顾性分析1998-2004年377例手助式腹腔镜肾切除术患者资料,其中根治性肾切除术206例,单纯性肾切除术91例,根治性肾、输尿管切除术49例,肾部分切除术31例,对围手术期并发症类型、发生率及处理方法进行统计分析。结果377例患者术中估计失血量平均315.6 ml(30~7000 m1)。术中发生脾脏损伤、难以控制的出血、肠道损伤、肾蒂血管损伤、胰腺损伤等并发症14例(3.7%)。中转开放手术13例(3.4%)。术后发生肠梗阻、肺炎、切口疝、继发性出血、冠心病发作、血管栓塞、低钠血症等并发症48例(12.7%)。死亡2例(0.5%)。有腹腔或腹膜后手术史者围手术期并发症和术式中转率高于无手术史者。结论手助式腹腔镜。肾切除术仍会出现一些严重的围手术期并发症。局部粘连、肿瘤体积过大会增加并发症的发生。术中一旦出现严重出血、器官损伤等难以控制的并发症时应及时中转开放手术。充分的术前准备、正确熟练的手术操作可降低并发症的发生率。李爱华 Leonard G.Gomella Ramsay Kuo Dolores Shupp-Byrne Mark Chang Stephen Strup Demetrias H.Bagley 2006中华泌尿外科杂志2006,27,10:2
13Crystal structure of Lamellipodin implicates diverse functions in actin polymerization and Ras signaling显示文摘The adapter protein Lamellipodin(Lpd)plays an important role in cell migration.In particular,Lpd mediates lamellipodia formation by regulating actin dynamics via interacting with Ena/VASP proteins.Its RA-PH tandem domain confi guration suggests that like its paralog RIAM,Lpd may also mediate particular Ras GTPase signaling.We determined the crystal structures of the Lpd RA-PH domains alone and with an N-terminal coiled-coil region(cc-RA-PH).These structures reveal that apart from the anticipated coiled-coil interaction,Lpd may also oligomerize through a second intermolecular contact site.We then validated both oligomerization interfaces in solution by mutagenesis.A fluorescence-polarization study demon-strated that Lpd binds phosphoinositol with low affinity.Based on our crystallographic and biochemical data,we propose that Lpd and RIAM serve diverse functions:Lpd plays a predominant role in regulating actin polymerization,and its function in mediating Ras GTPase signaling is largely suppressed compared to RIAM.Yu-Chung Chang Hao Zhang Mark LBrennan Jinhua Wu 2013Protein & Cell2013,4,3:2
