目的:研究自体肋软骨“瓦合支架法”在鼻综合整形术中的临床应用效果。方法:纳入158例实行鼻综合整形术的就医者,选取右侧第7肋内侧部分肋软骨作为鼻中隔延伸移植物(Septal extensional graft,SEG)、鼻小柱支撑移植物(The nasal columella support graft,STRUT),按照“瓦合支架法”塑造鼻形,收集术前、术后鼻部照片,测量鼻部形态数据,行统计学处理。结果:153例就医者术后愈合良好,无鼻部形变,歪曲,鼻形态明显改善;5例出现切口感染。鼻宽/鼻高、鼻根宽/鼻高及鼻根高/鼻高术前术后比较差异无统计学意义(P>0.05);鼻尖高/鼻高及鼻背长/鼻高较术前有所改善,差异有统计学意义(P<0.05)。就医者满意度为94%。结论:自体肋软骨“瓦合支架法”在鼻综合整形术中的应用对于抬高鼻尖、延长鼻背、改善鼻部整体美学形态及减少术后并发症均有明确的改善效果。

目的分析肝移植术后重度高乳酸血症的危险因素,为临床采取有效预防措施提供依据。方法回顾性分析2021年1—12月于我院行肝移植手术的120例患者的临床资料,根据其术后动脉血乳酸(LAC)值分为重度高乳酸血症组与非重度高乳酸血症组。绘制趋势折线图分析所有患者围术期血生化指标与动脉血LAC水平的关系,采用χ2检验、t检验、非参数检验及多因素logistic回归模型分析上述指标对肝移植术后重度高乳酸血症的影响。结果趋势折线图显示,所有患者手术前3 d至手术后第3天的血清谷丙转氨酶水平、谷草转氨酶水平、白蛋白水平及血浆国际标准化比值、凝血酶原时间随时间变化的趋势与动脉血LAC变化一致。单因素分析结果显示,两组患者的原发病构成比、术中无肝期时间、术中总入量、术中出血量、术中输注红细胞量比较均差异有显著性(χ^(2)=10.579,U=-2.811~-2.183,P<0.05)。多因素logistic回归分析显示,术中无肝期时间延长和术中输注红细胞量增多为肝移植患者术后重度高乳酸血症的独立危险因素(P<0.05)。结论肝移植术中无肝期时间延长及术中输注红细胞量增多是肝移植术后重度高乳酸血症的独立危险因素。

Advances in Remote Sensing 2018年第3期7卷 259-275页

作者： Ali Imam Mirza Ali Iqtadar Mirza Tabasam Jamal Syed Shehzad Hassan Muhammad A. Butt Atif Ali Hafsa Batool Rashid Mahmood Attia Naz Azam Sohail imran Saddique Kaukab Sana Alvi Javed Ahmad Safeer Ali Muneeb Aamir Azeem Akhtar Arshad Javed Department of Geography GC University Lahore Pakistan Remote Sensing Group Department of Space Science University of the Punjab Lahore Pakistan

The contamination of drinking water in Pakistan is a serious threat to its citizens. Urbanization leads to an increased demand of drinking water supply that leads to excessive drawdown that further causes lowering of water table. The current WASA (Water and Sanitation Authority) supply network does not fulfill the demand of a growing metropolitan city of Lahore. The drawdown of Lahore is absolutely reliant on Water and Sanitation Authority (WASA) water supply network that causes numerous problems due to inappropriate management of groundwater capital and increased urbanization. This research investigates groundwater qualities: Alkalinity, Arsenic, Calcium, chloride, Total Hardness, Magnesium, Nitrate, pH and Total Dissolved solids using geographic information system (GIS). Residents of high concentrated towns, like Samnabad Town, Allama Iqbal Town, Gulberg, Data Ganj Bakhsh Town, Ravi Town and Wahga town witness cut-down of water supply mainly due to over burden on tube wells. Chemical properties of drinking water show that most of the parameters were within the allowable limits of WHO whereas the pH, and arsenic values are higher than the average. Arsenic is a carcinogenic element which causes cancer and is higher in the drinking water. Finally, this study identifies highly contaminated groundwater zones and makes it convenient to find actual pollutants. Therefore, plans are needed to protect the aquifer.
