背景:阑尾切除术是一个切除阑尾的外科手术,阑尾大约6英寸长或者更短,是大肠的分支。有两种方法来执行这个手术分别是开腹和腹腔镜。在微创手术过后,腹腔镜手术的并发症发生率在多年来持续减少。腹腔镜阑尾切除术尚未被一致认为是治疗急性阑尾炎的第一首选,由于其较长的手术时间,手术时腹腔脓肿的风险,并且成本要比开腹阑尾切除术。另一种方法是开腹切除。外科医生定位阑尾并通过切口切除阑尾。与任何外科手术一样,都有可能发生并发症。本文的主要目的是定性地回顾最近在复杂的阑尾炎中进行的腹腔镜手术和开腹手术的随机对照试验。本论文还将详细介绍这两个程序的优点和缺点以及复杂性,使读者对这两种程序有全面的了解。根据大量的研究以及发表的文章和期刊表明,这两种手术都是具有多重优势以及常见的,并且是积极的结果,两者仍然具有并发症的风险,而且有着让人不满意的美容效果的缺点。目的:本论文的主要目的是对两个最近进行的随机对照试验进行了系统的回顾性分析,并得出结论方法:自从2006年开始到2016年为止,从多个在线可用的数据库进行搜索,两个rct采用开腹与腹腔镜阑尾切除术及复杂性阑尾炎的相关术语,在数据库pubmed,cochrane和embase。rct在纳入和排除标准之后可以免费以及公共观看的。这两个rct曾通过jadad评分系统的审查和评分,进行递归抽取,并且将两个实验缩减至总结版本。prisma图证明了搜索随机对照实验的过程,以及总结。没有使用软件并使用笔和纸进行审查。还应注意的是,试验不再是免费的,thomson的试验报告可在“researchgate”免费获得,但taguchi的试验不再可用,必须购买且在本研究期间均可用。meta分析没有进行,本系统综述以叙述形式提供。还有许多其他研究以同样的方式进行,否则被称为只是系统的审查或实证研究定性分析。结果:从众多的研究和发表的文章缩小到了只有2项2014和2015年施行了,本文只涉及在复杂的情况下的随机对照试验,在thomson2014年的试验中有提到过,这是有史以来第一个rct针对la和oa。本次审查的重点是手术时间,转换率,术后住院时间,并发症,发病率和恢复到正常活动。这项审查也以定性的方式系统地分析了这两个试验。结论:通过仔细分析递归抽象的数据提取和通过JADAD的试验进行分级后,显然可以说腹腔镜手术治疗复杂阑尾炎是安全和可行的,但没有发现任何腹腔镜超过开腹式的特征。

Wheat is a strategic crop for food security in Pakistan with predominance of smallholder farmers. Farmer-saved seed （FSS） is used nearly by 75% of farmers for wheat production. Frequent variety or seed replacement is uncommon even among large-scale farmers, and certified seed （CS） is mostly bought to verify the value of new varieties. Replacing old and obsolete varieties by new high yielding disease resistant varieties is key to transferring new genetic gains to farmers. For the first time in Pakistan, on-farm factorial experiments involving seven new and five old wheat varieties and their corresponding CS and FSS were conducted. A total of 49 farmers representing major wheat cropping patterns throughout the country participated in these trials in the 2014 and 2015 wheat growing seasons. Analysis of variance revealed that there was highly significant difference between wheat varieties and between seed classes. New variety ＋ CS gave 33.8% more grain yield as well as higher marginal return over farmers＇ variety ＋ FSS. Grain yield and returns from new variety ＋ FSS and farmers＇ variety ＋ CS were at par. Scientific knowledge generated in this research demonstrated that use of CS ＆new wheat varieties is best option, while growing new varieties with FSS is a second choice for the advantages accruing from their built-in genetic traits of economic importance over growing CS of old and obsolete varieties. Having more flexible seed system will help accelerate the delivery of new genetic gains to farmers＇ fields.

·AIM:To identify various risk factors that may play a significant role in the development of congenital nasolacrimal duct obstruction(CNLDO).·METHODS:This observational case-control study included a case group of 122 children less than two years of age with CNLDO who underwent probing and irrigation treatment at the ophthalmology department of Imam Khomeini Hospital in Ahvaz,Iran,from June 2022 to June2024.A control group of 122 age-matched children without CNLDO was also included for *** was collected from the children's medical records.·RESULTS:The study found a significant correlation between the occurrence of CNLDO and several maternal factors,such as preeclampsia,the use of levothyroxine,hypothyroidism,having more than three pregnancies(gravidity>3),natural pregnancy,and gestational diabetes ***,in children,factors,such as oxygen therapy,anemia,reflux,jaundice,and a family history of CNLDO in first-degree relatives were associated with CNLDO,and maternal preeclampsia and hypothyroidism were found to significantly increase the risk of developing CNLDO in children.·CONCLUSION:Given that CNLDO affects both premature and full-term children,the present findings may potentially facilitate the early identification of children and infants at risk of nasolacrimal duct obstruction,thereby preventing the onset of chronic dacryocystitis.

The Late Cretaceous Chagai arc outcrops in western Pakistan, southern Afghanistan and eastern Iran. It is in the Tethyan convergence zone, formed by northward subduction of the Arabian oceanic plate beneath the Afghan block. The oldest unit of the Chagai arc is the Late Cretaceous Sinjrani Volcanic Group. This is composed of porphyritic lava flows and volcaniclastic rocks, and subordinate shale, sandstone, limestone and chert. The flows are fractionated low-K tholeiitic basalts, basaltic- andesites, and andesites. Relative enrichment in their LILE and depletion in HFSE, and negative Nb and Ta and positive K, Ba and Sr anomalies point to a subduction-related origin. Compared to MORB, the least fractionated Chagai basalts have low Na2O, Fe2O3^T, CaO, Ti, Zr, Y and ^87Sr/^86Sr. Rather than an Andean setting, these results suggest derivation from a highly depleted mantle in an intraoceanic arc formed by Late Cretaceous convergence in the Ceno-Tethys. The segmented subduction zone formed between Gondwana and a collage of small continental blocks （Iran, Afghan, Karakoram, Lhasa and Burma） was accompanied by a chain of oceanic island arcs and suprasubduction ophiolites including Semail, Zagros, Chagai-Raskoh, Kandahar, Muslim Bagh, Waziristan and Kohistan-Ladakh, Nidar, Nagaland and Manipur. These complexes accreted to the southern margin of Eurasia in the Late Cretaceous.
