大学生健康概念认知的调查研究

随着教育改革的深化,健康教育日益成为高校素质教育的热点课题。现代健康理念建立在“生物-心理-社会医学模式”之上,1978年WHO在《阿拉木图宣言》中指出:“健康不仅是没有疾病或不虚弱,而且是身体的、精神的健康和社会适应的完美状态。”[1]依据这一健康观的指导,笔者认为高校健康教育机构应该从机体健康、心理健康、行为与社会适应性健康几方面对学生的健康观和保健能力进行培养。为了解目前大学生对“健康”的理解和认识水平,进一步为高校有针对性的健康教育实践提供依据,笔者在广州市两所综合大学对学生的健康概念认知情况进行调查。1…     

联合应用经腹腹膜前腹腔镜疝修补术和腹腔内网片植入术治疗成人腹股沟疝

目的联合应用经腹腹膜前腹腔镜疝修补术(transabdominal preperitoneal prosthetic,TAPP)和腹腔内网片植入术(intraperitoneal onlay mesh,IPOM),探讨理想的腹腔镜下腹股沟疝修补的方法。方法2006年1月~12月,对30例成人腹股沟疝行腹腔镜下修补。以腹壁下血管内侧缘为界,把疝薄弱区纵行分成内侧和外侧,内侧采用改进的TAPP方法,外侧仍用IPOM方法。沿腹壁下血管内侧缘纵行剪开腹膜后向内侧游离的区域内基本上是无血管区,亦无重要的神经,组织疏松极易游离,数分钟内即可分离出所需要的面积(7.5 cm×6.5 cm)。补片的材料亦分为内侧和外侧,内侧是聚丙烯材料,外侧应用Proceed补片。结果30例均在硬膜外麻醉下完成,手术时间单侧30~40 min,平均35 min,双侧50~60 min,平均55min,术中出血1~5 ml,术后第2天可离床活动,术后3~4天出院,术后2周均恢复工作。术后随访2~12个月,平均9个月,无粘连性肠梗阻,腹股沟部和全身无不良反应。结论联合应用TAPP和IPOM后,能体现微创的原则,易掌握,损伤少,手术时间短,恢复快,手术效果确切。     

Performance and comparison of the Cockcroft-Gault and simplified Modification of Diet in Renal Disease formulae in estimating glomerular filtration rate in a Chinese Type 2 diabetic population.

AIMS: Our aim was to assess performances of the Cockcroft-Gault and simplified Modification of Diet in Renal Disease (MDRD) formulae in estimating glomerular filtration rate (GFR) in Chinese diabetic populations and their association with vascular risks. METHODS: A total of 1009 patients with Type 2 diabetes were categorized into low estimated GFR groups (GFR < 60 ml/min/1.73 m(2)) and control groups by the two equations. The performances of these formulae were assessed at different stages of kidney function. Carotid artery intima-media thickness (IMT) and the prevalence of diabetic retinopathy or albuminuria were compared among the groups. The ability of these formulae to identify established vascular risk markers using sensitivity, specificity, positive and negative predictive values were also compared. RESULTS: The prevalence of low estimated GFR was 32.7% with the Cockcroft-Gault formula and 5.2% with the MDRD formula, respectively. In low estimated GFR subjects by the MDRD formula, IMT was significantly thicker than those by the Cockcroft-Gault formula (1.2 mm vs. 1.0 mm; P < 0.05), with a higher prevalence of albuminuria (78.4 vs. 52.8%, P < 0.05) and diabetic retinopathy (46.5 vs. 30.5%; P < 0.05). The Cockcroft-Gault formula gave a specificity of 71.7% and a sensitivity of 37.0%, and the MDRD formula gave a specificity of 96.6% and a sensitivity of 7.9% in estimating low GFR relevant for established vascular risks. CONCLUSIONS: These formulae performed differently in Chinese diabetic populations. The simplified MDRD formula is minimally superior to the Cockcroft-Gault formula for its high specificity and positive predictive values in estimating low GFR relevant for vascular risks.     

“黄风湿”系列疗法——火针封闭治疗痛风石的疗效观察

痛风是一种由嘌呤代谢紊乱所致的疾病,日久不愈、反复发作则逐渐形成痛风石沉积。常规治疗对痛风石效果不明显。黄再军医院采用火针封闭疗法治疗痛风石36例,经临床观察治愈率为69.4%,显效率为25.0%,有效率为5.6%,总有效率达100%。     

乳腺非典型增生病与血管生成关系的实验研究

目的：建立乳腺非典型增生病动物模型，探讨非典型增生与血管生成的关系。方法：采用灌服二甲基苯蒽＋颈部枷具方法复制大鼠肝郁血瘀型乳腺非典型增生动物模型，并给予中药乳复汤治疗。常规染色观察大鼠乳腺组织病理组织形态．免疫组化方法检测MVD、VEGF和bFGF的表达。结果：病证模型组乳腺非典型增生率90％．较单纯造模组高．P=0．0415；中药乳复汤治疗组非典型增生率较病证模型组低．P=0．0459；随着一般增生到非典型增生程度加重，MVD计数增多，VEGF、bFGF的表达升高，P〈0．05。结论：病证结合造模更适合中医动物实验要求，中药乳复汤具有抑制血管生成作用。

面部烧伤病人感染危险因素的分析及护理

面部是人体的暴露部位,在烧伤病中占有较大比例。烧伤后很容易引起组织毁损及吸入性损伤,反复感染影响创面愈合,伤愈后常留有色素沉着、瘢痕增生、睑外翻、唇外翻等后遗症,影响面部美观及五官功能,给病人带来长期精神痛苦。我院1998年—2001年面部烧伤病人感染率为6.09%。因此,2002年—2005年,我科护理人员加强面部烧伤感染的防护措施,使其感染率下降到2.49%。正确的护理干预可以有效预防病人感染,减轻各种并发症的发生。现对面部烧伤病人的护理干预报告如下。1临床资料我科2002年—2005年共收治烧伤病人558例,其中面部烧伤281例,男195例,女…

Inhibition of the ubiquitin-proteasome system: a new avenue for atherosclerosis.

BACKGROUND: The ubiquitin-proteasome system (UPS) is thought to be functionally active in atherosclerosis (AS) lesions. Aspirin was found to be a potent inhibitor of the UPS in some tumour studies; however, its effect on AS remains to be demonstrated in vivo. METHODS: New Zealand rabbits were placed on a normal diet (N) or on a normal diet with aspirin (NI) or on an atherogenic diet without (H) or with aspirin (HI) for 12 weeks. Proteasome activity, concentrations of plasma lipids and levels of peroxidation were determined. Ubiquitin/ubiquitin-conjugates (Ub), IkappaBalpha, phosphorylated IkappaB (pIkappaBalpha) and p65 were investigated by Western blotting or immunochemistry. RESULTS: Concentrations of plasma lipids and peroxidation levels were higher in H or HI vs. N or NI. Histological analysis showed that atheroma was increased in H. Ub and IkappaBalpha were mainly localised in subendothelium and media vascular smooth muscle cells. Western blots revealed that Ub, IkappaBalpha, and pIkappaBalpha were increased, whereas p65 was lower in HI vs. H. The activity of the 20S proteasome was functionally active in H vs. N, NI or HI, while the 26S proteasome was not affected in any of the groups. CONCLUSIONS: Aspirin can attenuate the pathogenesis of atheroma formation, the degradation of IkappaBalpha and pIkappaBalpha, and lower the expression of p65, indicating that its therapeutic effects on AS may be via inhibition of the UPS.
