Background: Cervical insufficiency is one of the major causes of preterm birth among pregnant women that leads to severe mortality and morbidity issues among newborns. Prophylactic cervical cerclage is a surgical procedure performed between 11 and 14 weeks of gestation upon diagnosis of cervix insufficiency among pregnant women. Aims & Objectives: In this study, we aimed to evaluate the effectiveness of prophylactic cervical cerclage in comparison to other interventions to treat cervical insufficiency among pregnant women using a meta-analysis approach. Methods: We searched the three databases (Coachrane Library, PubMed, and MEDLINE) that were used for articles related to research aims by using MeSH keywords. The timeline of research was set from January 2015 to January 2024. The methodological quality assessment of included studies was performed by the Risk of Bias in Non-randomized Studies—of Interventions (ROBINS-I). A recent meta-analysis was conducted by using Review Manager 5.4.0 software. Results: About 441 research articles were extracted from three electronic databases and only 125 articles were assessed for eligibility criteria. Finally, 8 studies were included in the analysis for a recent meta-analysis. Six out of eight included retrospective or pilot studies were graded as having a moderate risk of bias, and two studies had low risk on the basis of owning bias. About 1008 pregnant women with cervical insufficiency were analyzed in a recent meta-analysis. By pooled analysis, it was evaluated that significant difference found in prolongation of delivery weeks (Mean difference = 1.05;cl: 0.81 to 1.29: p > 0.00001), number of deliveries > 37 weeks (OR = 0.59;cl: 0.19 to 1.84: p > 0.006), and preterm birth (OR = 0.73;cl: 0.42 to 1.28: p > 0.50) among pregnant women receiving prophylactic cervical cerclage as compared to other treatment strategies. Conclusion: Recent meta-analysis suggested the prophylactic cervical cerclage reduces the rates of preterm birth,

High-intensity focused ultrasound ablation as a bridging therapy for hepatocellular carcinoma patients awaiting liver transplantation

引用

Hepatobiliary & Pancreatic Diseases International 2012年第5期11卷 542-544页

作者： Tan To Cheung Kenneth SH Chok Regina cl Lo William W Sharr See Ching chan Ronnie TP Poon Sheung Tat Fan Chung Mau Lo Department of Surgery The University of Hong Kong Department of Pathology The University of Hong Kong State Key Laboratory for Liver Research The University of Hong Kong

The scarcity of liver grafts in Asia leads to a significant dropout of patients from liver transplant waiting lists, particularly patients with hepatocellular carcinoma and a low model for end-stage liver disease score. In order to reduce dropping out, different bridging therapies are employed. We report the use of high-intensity focused ultrasound ablation as a bridging therapy for a patient with hepatocellular carcinoma of stage two and an extremely low platelet count (20×10 9 /L). The ablation was successful. Blood tests showed that his liver function was similar before and after the treatment. No adhesion was encountered in the liver transplantation performed six months later.

随机对照试验报告规范声明(consolidated standards of reporting trials,CONSORT)是一个旨在提高随机对照试验(randomized controlled trial,RCT)报告透明度和质量的指南。本扩展版针对将来确定性RCT之前所进行的随机先导性和可行性试验制定统一报告规范。该清单适用于任何随机研究,其中包括确定性RCT及此前的、在小规模研究样本下进行的任何先导性试验,而其设计(如聚类、析因、交叉)或作者用来描述该研究的术语(如先导性(试验)、可行性(试验)、试验、研究)并不会对此造成影响。不过,需要注意的是,本报告规范扩展范围不直接适用于主要试验设计中内置的先导性试验、非随机的先导性和可行性试验,或者Ⅱ期临床试验。不过这些研究都与随机先导性和可行性试验有一定相似性,因此许多原则也同样适用。本扩展版的研发是因为越来越多的研究被描述为可行性试验或先导性试验,但这些研究的报告和实施存在缺陷。我们遵循了所推荐的良好实践来研发CONSORT先导性和可行性试验扩展版,其中包括进行德尔菲调查、召开共识会议和研究团队会议及试行此条目清单等。由于先导性试验和可行性随机试验的目的和目标不同于其他随机试验,因此,尽管在这些试验报告中的许多内容,与评估效果和效力的RCT中的报告内容相似,但在报告内容类型、报告条目解释方面,其与标准CONSORT存在一些关键差异。本文保留了部分标准CONSORT声明的条目,但仔细阅读就会发现,其中大多数条目已经被修改或删除,并且添加了一些新的条目。其中,新增条目包括:如何识别受试者并获得同意;如果适用,用于判断是否或如何进行将来确定性RCT的预先制定的标准;如果相关,其他重要的非预期结果;先导性试验的结果对将来确定性RCT的影响,还包括任何拟定的修正及伦理批准或研究审查委员会的批准,并要求附有获准批号。本扩展版包括26个条目清单、摘要的单独清单、研究的流程图模板及对所做条目更改的解释和相关范例。我们相信,使用CONSORT先导性和可行性试验扩展版,将提高先导性试验的报告质量。

目的:探讨牛磺胆酸钠对小鼠胰腺腺泡细胞氯通道的激活作用及途径。方法:胶原蛋白酶消化分离FVB/N小鼠胰腺腺泡细胞,采用膜片钳技术记录牛磺胆酸钠激活的全细胞电流;去除电极内液配方中的三磷酸腺苷(ATP),观察其胞内ATP依赖性;阴离子置换实验分析其阴离子选择性;利用氯通道阻断剂检测其药理学特性;采用47%高渗灌流液观察其容积敏感性;清除胞外等渗灌流液中的Ca^(2+)分析通道激活对胞外Ca^(2+)的依赖性;使用透膜荧光探针2',7'-二氯荧光黄双乙酸盐检测胞内活性氧(ROS)水平。结果:5 mmol/L牛磺胆酸钠可激活小鼠胰腺腺泡细胞产生电流,该电流呈外向整流优势,对细胞内液的ATP具有依赖性,其阴离子通透性顺序为:I->Br^(−)≥cl^(−)>gluconate-(P<0.01);该电流能被氯通道阻断剂4,4'-二异硫氰酸十八烯-2,2'-二磺酸二钠盐水合物(DIDS)和tamoxifen抑制,且可被细胞外47%高渗刺激阻抑(P<0.01)。N-乙酰-L-半胱氨酸清除细胞内ROS不能阻断牛磺胆酸钠诱导胰腺腺泡细胞产生氯电流;氯通道阻断剂DIDS不影响牛磺胆酸钠诱导的ROS生成。清除细胞外Ca^(2+)后,牛磺胆酸钠未能诱导胰腺腺泡细胞产生氯电流。结论:牛磺胆酸钠可激活小鼠胰腺腺泡细胞氯通道,该通道的激活对胞外Ca^(2+)具有依赖性,但不依赖于ROS途径。

超级双相不锈钢(SDSS)因优异的耐蚀性和卓越的力学性能以及性价比高等优势,在烟气脱硫领域具有广阔的应用前景。以2507 SDSS为研究对象,利用金相显微镜、扫描电子显微镜及电化学工作站等手段,对其在不同温度(20、40、60、80℃)烟气脱硫冷凝液中的点蚀行为进行深入研究。结果表明,当溶液温度为40℃时,试验钢的自腐蚀电位(Ecorr)为-0.078 V,自腐蚀电流密度(icorr)为5.09 mA/cm^(2),点蚀电位(Epit)为0.956 V,阻抗谱半径最大,电荷转移电阻(Rct)为54200Ω/cm^(2),频率为0.01 Hz的阻抗模值|Z|f=0.01 Hz为52036Ω,其耐蚀性最好。当溶液温度从20℃升高到80℃时,试样的Ecorr、Epit先增大后减小,icorr先减小后增大,电化学阻抗谱半径先增大后减小,Rct先增大后减小,腐蚀后点蚀坑数量先减少后增多,耐点蚀性能呈现先升高后降低的规律。分析认为这是温度对电化学过程的2个相反作用(氧含量降低的阻滞效果和离子活性增强的促进效果)的综合影响结果。当温度低于或处于40℃时,溶解氧的质量浓度减少,cl^(-)的活性、反应能力较弱,氧含量降低的阻滞效果占主导作用。随温度升高,2507 SDSS耐点蚀性能提升。当温度高于40℃时,过高的温度会增强腐蚀性卤素离子的活性及其反应能力,cl^(-)活性增强的促进效果占主导作用。随温度升高,2507 SDSS耐点蚀能力降低。

Ultrafine nano-scale Cu2Sb alloy confined in a three-dimensional porous carbon was synthesized using Nacl template-assisted vacuum freeze-drying followed by high-temperature sintering and was evaluated as an anode for sodium-ion batteries(SIBs)and potassium-ion batteries(PIBs).The alloy exerts excellent cycling durability(the capacity can be maintained at 328.3 mA·h·g^(-1) after 100 cycles for SIBs and 260 mA·h·g^(-1) for PIBs)and rate capability(199 mA·h·g^(-1) at 5 A·g^(-1) for SIBs and 148 mA·h·g^(-1) at 5 A·g^(-1) for PIBs)because of the smooth electron transport path,fast Na/K ion diffusion rate,and restricted volume changes from the synergistic effect of three-dimensional porous carbon networks and the ultrafine bimetallic *** study provides an ingenious design route and a simple preparation method toward exploring a high-property electrode for K-ion and Na-ion batteries,and it also introduces broad application prospects for other electrochemical applications.
