目的：对比分析支气管动脉灌注化疗与支气管动脉灌注化疗十栓塞术治疗中晚期肺癌的临床疗效。方法：将我院2011年1月-2013年1月期间收治的76例中晚期肺癌患者随机分为两组,即观察组38例,对照组38例。观察组患者行支气管动脉灌注化疗联合栓塞术治疗,对照组患者行单纯支气管动脉灌注化疗治疗。分别对两组患者治疗后的临床治疗效果进行评价,同时观察两组患者治疗后的不良反应及并发症的发生情况。结果：观察组患者临床治疗的总有效率为84．21％,对照组为64．78％．两组比较,差异具有统计学意义（P〈0．05）。两组患者治疗后,观察组患者总不良反应率为23．67％,对照组为21．04％,两组比较．差异无统计学意义（P〉0．05）。且经对症处理后,均得到有效改善。结论：支气管动脉灌注化疗联合栓塞术治疗中晚期肺癌的,临床疗效明显优于单纯支气管动脉灌注化疗,且无明显不良反应及并发症的发生,安全性好,值得临床推广与应用。     

The effect of aortic valve replacement on quality of life in symptomatic patients with severe aortic stenosis

Background

Although symptomatic patients with severe aortic stenosis have a high disease burden and guidelines recommend aortic valve replacement, many are treated conservatively. This study describes to what extent quality of life is changed by aortic valve replacement relative to conservative treatment.

Methods

This observational study followed 132 symptomatic patients with severe aortic stenosis who were subjected to an SF-36v2TM Health Survey.

Results

At baseline 84 patients were treated conservatively, 48 were referred for aortic valve replacement. In the conservatively treated group 15 patients died during a mean follow-up of 18 months (Kaplan-Meier survival was 85 % and 72 % at one and 2 years respectively) and 22 patients crossed over to the surgical group. Of the resulting 70 patients in the surgical group 3 patients died during a mean follow-up of 11 months (survival 95 % at 1 year). Physical functioning, vitality and general health improved significantly 1 year after aortic valve replacement. In conservatively treated patients physical quality of life deteriorated over time while general health, vitality and social functioning showed a declining trend. Mental health remained stable in both groups.

Conclusions

Aortic valve replacement improves physical quality of life, general health and vitality in patients with symptomatic severe aortic stenosis. Besides having a low life expectancy, conservatively treated patients experience deterioration of physical quality of life. Health surveys such as the SF-36v2TM can be valuable tools in monitoring the burden of disease for an individual patient and offer additional help in treatment decisions.     

两种途径介入治疗急性心肌梗塞疗效分析

目的：探讨对急性心梗患者行不同途径急诊经皮冠状动脉治疗（PCi）的临床疗效及预后。方法：选取我院自2011年1月至2012年12月收治的75例sT段抬高的急性心肌梗死患者作为研究对象进行回顾性调查,对比分析经桡动脉PCI（TRA—Pet）和经股动脉PCI（TFA—PCI）两组治疗疗效及出现并发症情况,包括比较两组穿刺成功率,手术时间,术中出血及术后局部及其他并发症等方面,并作统计分析,取P〈0．05为有统计学意义。结果：两组穿刺成功率及PCI手术成功率差异无统计学意义,P〉0．05。在手术操作时间上,TFA—PCI组明显长于TRA—PCI组,差异有统计学意义,P〈0．05。TFA．PCI组局部并发症发生率为11．8％．远期并发症为2．9％。TRA-PCI组局部并发症发生率为2．4％,远期并发症为7．3％,两组差别显著,P〈0．05。结论：TRA—PCI和TFA—PCI在手术时间及术后并发症上有差异,TRA—PCI术中花时间较少,术后局部并发症要轻,值得在临床上推广,但是由于有远期并发症的危险,故术后应加强肝肾功能等的监测。     

剖宫产术后切口妊娠介入治疗与保守治疗效果的临床研究

目的:研究子宫动脉介入化疗栓塞术在临床上对剖宫产切口妊娠的治疗效果.方法:回顾性分析我院2007年1月至2012年12月的收治的切口妊娠患者53例.并将53例患者随机分为介入治疗组28例、保守治疗组25例,介入治疗组患者采用双侧子宫动脉栓塞术后进行刮宫术的治疗,保守治疗组患者采用口服米非司酮以及肌内注射MTX后进行刮宫术的治疗.对两组患者的临床资料包括出血量,住院时间,降血HCG时间等进行统计学分析.结果:介入治疗组患者的出血量,住院时间,降血HCG时间明显低于保守治疗组患者的情况,差异具有显著性(P＜0.05).介入治疗组和保守治疗组间的不良反应差异无统计学意义(P＞0.05).结论:对患者采用子宫动脉介入对剖宫产切口妊娠进行治疗的方式,可以对切口妊娠大出血进行有效的控制,同时也可以对妊娠物进行有效的杀死.     

晚期早产儿颅内出血的相关因素分析

目的：探讨晚期早产儿颅内出血的相关因素,指导晚期早产儿颅内出血的防治。方法：2011年9月至2012年8月我院收治晚期早产儿253例,其中有210例行头颅MRI检查,以经头颅MRI检查确诊颅内出血30例为ICH组,同时随机抽取同期住院的经头颅MRI证实无颅内出血晚期早产儿60例作为对照组。应用SPSS 17.0进行统计学分析。结果：1.ICH组产前激素应用率显著低于对照组（P〈0.05）。2.ICH组经阴分娩、胎膜早破、代谢性酸中毒发生率显著高于对照组（P〈0.05）。3.Logistic回归分析显示产前激素是颅内出血的保护因素（P〈0.05）,而经阴分娩、胎膜早破（P〈0.01）、代谢性酸中毒（P〈0.05）是颅内出血的危险因素。结论：产前应用激素是晚期早产儿颅内出血的保护因素,经阴分娩、胎膜早破、代谢性酸中毒是晚期早产儿颅内出血高危因素。     

Dietary partitioning of three large carnivores in Majete Wildlife Reserve,Malawi

Between 2011 and 2012, the carnivore guild in Majete Wildlife Reserve (MWR), Malawi, was restored following the reintroduction of lion (Panthera leo) and leopard (Panthera pardus). The aim of this study was to describe and compare the diet of lion, leopard and resident spotted hyaena (Crocuta crocuta) using scat analysis. Lions and spotted hyaenas displayed the greatest dietary overlap (O_ab = 0.88) and selected mainly medium- to large-bodied prey species. Lions had a mean preferred prey weight of 120.33 ± 42.14 kg (SE), with warthog (Phacochoerus africanus) and waterbuck (Kobus ellipsiprymnus) making up 60.64% of relative biomass consumed. Spotted hyaenas had a mean preferred prey weight of 102.40 ± 41.69 kg and had a more generalised diet (B_a = 0.46) compared to lions (B_a = 0.36). In contrast, leopards occupied a dietary niche substantially lower than that of lions and spotted hyaenas, selecting relatively smaller prey with a mean preferred prey weight of 27.50 ± 6.74 kg. Our results suggest that coexistence between the resident hyaena and reintroduced lion and leopard in MWR is facilitated by dietary partitioning. We advise long-term monitoring of reintroduced carnivores in small, enclosed reserves to assess their impacts on predator and prey populations.     

Pareuchiloglanis (Teleostei: Sisoridae) from the Pearl River,China with description of three new species

We describe three new species of Pareuchiloglanis. Based on a comparison of 17 valid species of Pareuchiloglanis, the genus can be divided into two groups contingent on their gill opening size and the anus position. One group, which we call the large gill opening group, has a large gill opening extending to the base of the first pectoral-fin element; the anus is obviously closer to pelvic-fin insertion than the anal-fin origin; this group includes five species distributed in the Red and Pearl Rivers, China. The other group has a small gill opening extending only to the middle base of the pectoral-fin elements; the anus is usually located at the midpoint of the pelvic-fin insertion to the anal-fin origin or slightly behind. This group includes the other 12 species, which are distributed in the Mekong and Yangtze Rivers. The large-gill-opening group can be divided into two sub-groups based on the length of the caudal peduncle. One sub-group has a long caudal-peduncle and the distance from the anal-fin origin to caudal-fin base is greater than distance from the pelvic-fin insertion. This sub-group is only distributed in the Pearl River drainage. Another sub-group has a short caudal peduncle and the distance from the anal-fin origin to the caudal-fin base is typically smaller than the distance from the pelvic-fin insertion. This sub-group is only distributed in the Red River basin of China and Vietnam. The former will be called the large-gill-opening group with long caudal peduncle in the text and only includes one species P. longicauda. During our ongoing taxonomic work of specimens collected from Nanpan-jiang and Beipan-jiang (upper Pearl River drainage in Yunnan, China), some Pareuchiloglanis specimens that had the characters of the large-gill-opening group with long caudal peduncle represent three undescribed species.
