高等职业学校护理专业中医教学现状调查

目的了解高等职业学校护理专业中医教学的现状.方法对省内外具有代表性的医学职业学校进行问卷调查,了解其护理专业中医课程设置情况及教学情况.同时,对职业大专毕业生进行问卷调查,了解其在临床护理工作中中医知识的运用情况.选择具有代表性的各级医院,对其管理人员及临床医生进行问卷调查,了解其在临床护理工作中中医知识的运用情况及对中医教学的建议.结果在护理实践中多数护士需要运用中医知识护理患者,但临床护士的中医知识贫乏,尤其是对中医护理的操作技能和中药方剂知识了解甚少,影响临床运用.学校的中医教学由于教学时数偏少等多种原因,无法安排充足的实践教学时间,有的操作只能看录像,学生没有动手的机会,更谈不上学以致用,出现了教学与临床严重脱节的局面.结论中医护理教学应进行改革,以适应护理专业学生和临床护理工作的需要.

血清脂联素、抵抗素与2型糖尿病

目的探讨人血清脂联素、抵抗素水平与2型糖尿病(T2DM)的关系。方法2型糖尿病患者47例和正常对照46例,两组年龄、性别匹配,采用酶联免疫分析法检测其空腹血清脂联素、抵抗素、胰岛素水平,同时测血糖、血压、血脂、身高、体重,计算腰/臀围、体重指数(BMI)、腰臀比值(WHR)和胰岛素敏感指数(ISI)、胰岛素抵抗性(HOMA-IR)、胰岛β细胞功能(HOMA-β)。结果2型糖尿病组的脂联素水平减低,脂联素水平在糖尿病超重组低于糖尿病正常体重组和对照组;相关分析显示脂联素水平与BMI呈负相关,与ISI正相关。而抵抗素水平在糖尿病超重组显著高于糖尿病正常体重和对照组(P<0.05)。相关分析显示抵抗素水平与BMI、腰围、空腹胰岛素、血压呈正相关,在对照组,与ISI、HOMA-IR、HOMA-β相关。结论脂联素、抵抗素可能参与胰岛素抵抗,与2型糖尿病的发生有关。[关键词]脂联素;抵抗素;2型糖尿病     

Recurrent corneal perforation and acute calcareous corneal degeneration in chronic graft-versus-host disease.

Keratoconjunctivitis sicca (KCS) is a common complication of graft-versus-host disease (GVHD), and may lead to corneal epithelial defect and melting. In contrast, recurrent corneal calcareous degeneration and perforation is rare. A 46-year-old woman developed chronic GVHD after bone marrow transplantation for aplastic anemia. Severe KCS with corneal melting and calcium deposits were noted in the left eye. Penetrating keratoplasty was performed because of corneal perforation, but poor re-epithelialization and calcium deposition recurred. Lamellar keratectomy and amniotic membrane transplantation (AMT) were performed, but acute calcareous degeneration developed with subsequent recurrence of corneal perforation. After regraft, AMT and tarsorrhaphy, the corneal graft remained clear for 3 months. However, breakdown of the corneal epithelium occurred 3 weeks after spontaneous separation of tarsorrhaphy. Six months later, corneal perforation recurred again along with exacerbation of GVHD. Regraft was performed, but the patient refused tarsorrhaphy and AMT. Poor re-epithelialization persisted after regraft. Corneal melting with impending corneal perforation ensued. Further corneal surgery was refused and the patient chose to undergo evisceration. This case demonstrates that the ocular complications of GVHD may be severe enough to lead to corneal perforation and calcareous degeneration that is recalcitrant to medical and surgical treatment.     

未足月胎膜早破的封闭疗法

1PPROM概况 未足月胎膜早破（preterm premature rupture of the membranes，PPROM）是指妊娠未满37周胎膜在临产前发生破裂。在所有妊娠中PPROM发生率为2％～3％，早产30％～40％由PPROM引发，PPROM孕妇中只有7．7％～9．7％的胎膜破损能够自然闭合，而60％～80％的孕妇在胎膜破裂7d内分娩，其中位潜伏期为6．6d。     

子癎前期子癎并发止血功能异常的特点与处理

止血功能包括血管壁、血小板、凝血与抗凝血的作用,后者又包括纤维蛋白溶解系统的功能。正常情况下,各部分功能平衡,保证血管内的血液呈流态;血管损伤时血栓形成以止血。正常妊娠中晚期,由于产后止血的需要,大多数凝血因子在肝脏合成增加,同时纤溶活性降低,处于生理性的高凝状态。子疒间前期、子疒间患者由于血管内皮细胞损伤,血小板活化、抗凝血酶Ⅲ消耗,使机体处于明显的血栓倾向,此种更高水平的高凝状态可导致子疒间前期严重并发症的发生,如弥散性血管内凝血(DIC)、胎儿生长受限。1子疒间前期、子疒间并发止血功能异常的特点1.1血小板…     

Molecular Characterization of Duck Hepatitis B Virus Isolated from Hubei Brown Ducks

The objective of this study was to characterize the genome structure of duck hepatitis B virus (DHBV) isolated from Hubei brown ducks. The natural carrier rate of DHBV in adult ducks from Hubei area was investigated and the DHBV DNA-positive serum screened out. The complete genome of a DHBV strain was amplified by polymerase chain reaction (PCR) and cloned into T vector and sequenced. The results showed that the carrier rate of DHBV in Hubei brown ducks was 10 %. This strain (GenBank accession number DQ276978) had a genome of 3024 nucleotides with three overlapping open reading frames encoding the surface, core and polymerase proteins respectively. Comparison of the strain with 17 DHBV strains registered in GenBank revealed a homology from 89.3 % to 93.5 % at the nucleotide level. The sequences of the structural and functional domains of these proteins were highly conserved. The strain was found to share more signature amino acids in the polymerase genes with the "Chinese" DHBV strains than those of the "Western" country strains. This finding was also corroborated by a phylogenetic tree analysis. Therefore, the DQ276978 might belong to a subtype of the Chinese DHBV strains.     

Vascular endothelial growth factor expressing mesenchymal stem cells improves cardiac function in chronic myocardial infarction in pigs

Transplantation of mesenchymal stem cells （MSCs） for myocardial reconstruction has shown promise in both animal models and human phase 1 clinical studies. Vascular endothelial growth factor （VEGF） is a strong therapeutic agent for treating ischaemia by inducing angiogenesis. The feasibility of ex vivo MSCs mediated gene transfer is documented. Matsumoto and colleagues have recently reported genetically engineered MSCs carrying VEGF165 delivery for revascularization in a model of acute myocardial infarction （MI）. The promising data from our laboratory in both angiogenesis and MSCs transplantation in cunicular heart model of acute MI have prompted us to attempt the combined and simultaneous application of the two strategies.

中国居民代谢综合征与脑卒中的相关性研究

目的探讨中国居民代谢综合征与脑卒中的关系。方法数据来源于2002年中国居民营养与健康状况调查,选择15岁以上人群48633例,其中男性23080例,女性25553例。代谢综合征的定义参考中华医学会糖尿病分会2004年建议的标准。结果单因素logistic回归分析表明,代谢综合征与脑卒中呈正相关,OR值为5.998(95%CI4.799~7.496),多因素分析调整年龄、性别、6类地区、教育程度、中重度体力活动时间、吸烟、饮酒后代谢综合征与脑卒中仍具有统计学相关性,OR值为3.114(95%CI2.432~3.987)。代谢综合征的所有组分中,高血压与脑卒中的相关性最强,且随着代谢综合征组分在个体聚集越多(趋势性检验P<0.0001),患脑卒中的可能性越大。结论中国居民代谢综合征与脑卒中的患病有关。
