Zolpidem induced nocturnal sleep‐related eating disorder (NSRED) in a male patient

Nocturnal Sleep‐Related Eating Disorder (NSRED) is a well‐documented sleeping disorder where the person is reported to experience bizarre eating behavior during sleep. Although various causes are implicated in this disorder, role of drugs cannot be ruled out. Here we narrate an interesting rare case report of a drug‐induced new onset NSRED, where a 45‐year‐old man on zolipdem performed an unexpected and bizarre eating behavior during somnambulistic state, type of which has not been reported earlier in the literature. The case falls under even rarer category as such behavior in sleep is reported mainly in woman. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009     

152例老年高血压病的诊治体会

目的:观察中西医结合治疗老年高血压的疗效。方法:将152例老年高血压患者随机分成两组,对照组76例采用西药治疗,治疗组76例除用西药治疗外辅助中药治疗。结果:治疗组显效30例,有效44例,总有效率97.4%;对照组显效24例,有效40例,总有效率为84.2%。结论:中西医结合治疗老年高血压有较好的疗效。     

双胎输血综合征29对临床分析

目的：探讨新生儿双胎输血综合征的临床表现及其合并症等问题。方法：对过去10年间收治的29对双胎输血综合征患儿资料进行回顾性分析。结果：双胎输血综合征患儿有一般双胎儿的临床共性，且双胎输血综合征患儿中受血儿出现病理临床表现及合并症较供血儿多且严重。结论：双胎输血综合征对受血儿危害更大，故临床上一旦确诊为双胎输血综合征，应对受血儿进行严密监护，若出现临床表现，并发生红细胞增多症，应积极采取治疗措施，以减少严重并发症及后遗症的发生。     

共培养诱导小鼠ES细胞向软骨细胞分化的初步研究

目的 探讨软骨共培养体系诱导小鼠ES细胞向软骨细胞分化的可行性.方法 GFP标记的小鼠ES细胞初步分化为EB后,将EB消化为单个细胞,同猪关节软骨细胞按一定比例(1∶3)昆合后接种于PGA材料,体外培养1周后植入裸鼠皮下3周取材.对照组为EB细胞接种组及软骨细胞接种组.取材后行连续冰冻切片,切片分别做荧光拍照,HE染色及甲苯胺蓝染色.结果 组织学结果显示,EB细胞接种组形成畸胎瘤;软骨细胞对照组形成软骨组织;实验组形成软骨组织和畸胎瘤的混合体.甲苯胺蓝染色结果和荧光照片对照结果显示,部分软骨组织GFP阳性,由小鼠ES细胞分化而来.结论 软骨共培养体系可以诱导小鼠ES细胞向软骨细胞分化,但得到的软骨组织不纯,混有畸胎瘤组织.     

水稻亚种间杂种优势利用研究

本试验探讨了华南双季稻区利用亚种同杂种优势的特点和问题,结果表明:当前,两系亚种问杂种一代主要存在的问题是结实率低和谷草比低;籼粳交杂种易受环境条件的影响;每穗实粒数和单株有效穗数是决定单株产量的重要因子;每穗实粒数增加的关键在于结实率的提高,本文还就提高结实率和谷草比等问题提出了意见。     

A Biomechanical Double Sac (Pericardium-Pebax) for Specially Shaped Artificial Ventricles: A Computerized Study to Evaluate Its Mechanical and Volumetric Properties

Abstract: For original ovoid shaped artificial ventricles. a biomechanical double sac consisting of a biological sac (porcine pericardium) as the blood contact interface and a synthetic sac (Pebax 3533) as the mechanical support to assume systolic-diastolic dynamic constraints was conceived. The volumetric and mechanical properties were assessed with a three-dimensional modeling of Pebax sacs and computerized simulations of their systolic distortions for both right and left ventricular configurations. The stresses and strains of these sacs were represented as quantitative mappings for a maximum end-systolic state and were below the respective threshold values above which the Pebax material is jeopardized for permanent structure impairment. After fatigue tests applied on Pebax strips under the alleged working conditions of Pebax sacs, the material structure was unchanged and maintained its intrinsic mechanical properties. The theoretical maximum stroke volumes were 74.4 cm³ and 62.4 cm for the left and right ventricular configurations, respectively. With these mechanical and volumetric features, the biomechanical double sac concept was considered valid and could be provided for a consequent specific total artificial heart.
