PS联合CPAP治疗新生儿呼吸窘迫综合征临床研究

目的通过研究肺表面活性物质(PS)结合持续气道正压通气(CPAP)治疗新生儿呼吸窘迫综合征(NRDS)的治疗效果,进一步指导NRDS的临床治疗。方法选取于2017年4月-2018年10月间在本院收治的80例确诊为新生儿呼吸窘迫综合征的患儿作为研究对象,随机将患儿分为试验组和对照组,对照组给予持续气道正压通气治疗,试验组在对照组的基础上联合使用PS治疗。结果试验组对于呼吸窘迫缓解的有效率明显高于对照组,在气管插管内滴入PS治疗后试验组的血气情况明显优于对照组,且试验组患儿副作用发生率明显低于对照组,以上指标差异具有统计学意义,P <0.05。结论 PS结合CPAP在新生儿呼吸窘迫综合征的治疗中疗效很好。     

后路枕骨髁螺钉技术研究进展

正枕骨、寰椎和枢椎共同构成了枕颈部活动的结构功能单位,即枕颈交界区~([1-2])。炎症、创伤、肿瘤及畸形等因素会导致枕颈交界区失稳,从而引起颈脊髓或神经根的损伤、麻痹及难以忍受的疼痛,甚至危及生命~([3-4])。后路内固定融合技术是治疗枕颈部失稳的重要手段,目前常用术式为枕骨螺钉技术,该技术较钢丝固定技术有更好的生物力学稳定

重型颅脑损伤的手术治疗

目的探讨重型颅脑损伤梯度减压的手术方法对预防术中脑膨出、降低死亡率及致残率的效果。方法对100例重型颅脑损伤患者采用分次减压手术方式及去骨瓣后，硬膜与颞肌筋膜瓣减张缝闭硬膜切口方法。结果40例脑肿胀患者术中脑嘭出6例占15．0％，死亡19例占47．5％；60例脑内血肿病人未发生脑膨出，死亡12例占20％。结论脑外伤后脑血管调节麻痹及血肿压迫继发脑水肿易造成脑膨出.术中分次减压降低了骨窗部位脑组织的顺应性，从而降低了局部的压力梯度，避免脑血管急性扩张，能有效防止脑膨出，降低死亡率及致残率。     

不同区域晶状体上皮细胞基因表达差异分析

【目的】比较不同区域猪晶状体上皮细胞的基因表达在转录组水平上的差异。【方法】解剖显微镜下分离晶状体前囊膜，将附着于其上的上皮细胞分为中央（直径为10．56mm）和周边两部分。分别提取两个样本的总RNAs并经PCR扩增，以Cy3和Cy5分别标记扩增的中央与周边部分的cDNA。与含7548个基因的表达谱芯片杂交，经图像分析，生物信息学处理获得基因表达在转录水平差异的相关信息。【结果】中央与周边区域的猪晶状体上皮细胞在转录组水平共鉴定出952个有效表达的基因点，其中差异表达基因261个．以中央区域为参照，周边上皮细胞mRNA上调137个，下调124个。差异表达基因主要涉及的功能有：细胞周期与凋亡、细胞骨架蛋白及细胞外基质、转录、细胞信号分子等。【结论】中央与周边区域猪晶状体上皮细胞基因表达在转录组水平上差异明显。这类差异呈明显的功能聚类。

Perspectives on Health Among Adult Users of Illicit Stimulant Drugs in Rural Ohio

CONTEXT: Although the nonmedical use of stimulant drugs such as cocaine and methamphetamine is increasingly common in many rural areas of the United States, little is known about the health beliefs of people who use these drugs. PURPOSE: This research describes illicit stimulant drug users' views on health and health-related concepts that may affect their utilization of health care services. METHODS: A respondent-driven sampling plan was used to recruit 249 not-in-treatment, nonmedical stimulant drug users who were residing in 3 rural counties in west central Ohio. A structured questionnaire administered by trained interviewers was used to collect information on a range of topics, including current drug use, self-reported health status, perceived need for substance abuse treatment, and beliefs about health and health services. FINDINGS: Participants reported using a wide variety of drugs nonmedically, some by injection. Alcohol and marijuana were the most commonly used drugs in the 30 days prior to the interview. Powder cocaine was used by 72.3% of the sample, crack by 68.3%, and methamphetamine by 29.7%. Fair or poor health status was reported by 41.3% of the participants. Only 20.9% of the sample felt they needed drug abuse treatment. Less than one third of the sample reported that they would feel comfortable talking to a physician about their drug use, and 65.1% said they preferred taking care of their problems without getting professional help. CONCLUSIONS: Stimulant drug users in rural Ohio are involved with a range of substances and hold health beliefs that may impede health services utilization.

Effects of magnetic resonance imaging diffusion gradient recalled echo on a patient with an intracranial hemorrhage presenting to the emergency department.

Generally, a computed tomography scan is conducted for the diagnosis of stroke in the emergency department, because these scans are easier and faster in the detection of stroke. If there are no signs of hemorrhage on computed tomography scan, an ischemic stroke is diagnosed and treated accordingly. A magnetic resonance imaging scan may be taken in order to verify ischemic stroke. This process may lead to improper treatment and is time consuming. To address this situation, case studies are presented in which magnetic resonance imaging diffusion-weighted imaging and gradient recalled echo were performed to detect hemorrhagic and ischemic stroke and particularly, subarachnoid hemorrhage, which is undetectable with a computed tomography scan.
