急性心肌梗死与肺炎衣原体关系的多因素分析

急性心肌梗死(AMI)属动脉粥样硬化性冠心病最严重的临床类型,而动脉粥样硬化(As)的感染机制日益受到人们的重视。本次研究旨在通过对AMI患者进行血清流行病学调查,探讨AMI与肺炎衣原体(Cp)感染的关系。     

Childhood abuse history and risk behaviors among teen parents in a culturally rooted, couple-focused HIV prevention program.

Pregnant and parenting adolescents living in inner cities are at risk for acquiring HIV through unprotected sexual activity. In addition to individual risk behaviors, a lack of socioeconomic and other environmental resources create risk environments that make certain communities vulnerable to both adolescent pregnancy and HIV/AIDS. Research indicates that adolescent parents, many who have histories of childhood trauma, may use their experience of young parenthood and the concomitant feelings of parental protectiveness as a source of renewed hope for their future. The purpose of this report is to explore the relationship between history of childhood abuse and high risk behaviors in adolescent Latino mothers and fathers enrolled in a randomized clinical trial of a culturally rooted, couple-focused HIV prevention program. In addition, this report describes the HIV prevention program that was designed specifically for young Latino parents wherein maternal and paternal protectiveness are viewed as intrinsic and developing critical factors that promote resiliency and motivate behavioral change.     

pH值对IFN-α2b、rIL-2、ADM合用维拉帕米对人肝癌细胞杀伤作用的影响

目的　观察培养液在 pH值为 6 .8、7.3、7.6条件下rIL - 2、IFN -α2b、ADM及合用维拉帕米对人肝癌细胞 74 0 4杀伤作用的影响。方法　MTT法于 96孔培养板上进行杀伤实验 ,测定培养液pH值分别为 6 .8、7.3、7.6状态下 ,rIL - 2、IFN -α2b、ADM、及与维拉帕米联合杀伤人肝癌细胞 70 4 0的差异。结果　pH值为 7.6状态下rIL - 2、IFN -α2b、ADM及合用维拉帕米杀伤效果最佳。pH值为 6 .8、7.3、7.6时 ,IFN -α2b都能增加ADM抗肿瘤作用 ,但pH值为 7.6时 ,IFN -α2b +ADM杀伤效果最佳。结论　在偏硷性环境下 ,rIL - 2、IFN -α2b、ADM及合用维拉帕米对肿瘤细胞杀伤效果最佳     

超声乳化联合小切口硬核白内障摘除的临床观察

目的 探讨贫困地区超声乳化联合小切口硬核白内障摘除联合PMMA人工晶状体植入手术的疗效。方法 对336例(336只眼)Ⅳ级以上核白内障行超声乳化联合小切口晶状体摘除联合PMMA人工晶状体植入术。结果 术后1天、3天视力在0．5以上分别为240只眼(71．4％)、265只眼(78．8％)。术中主要并发症为后囊破裂。术后主要并发症为角膜水肿、眼压升高。结论 超声乳化联合小切口晶状体摘除治疗Ⅳ级以上核白内障切口小，术后反应轻，散光小，并且视力恢复快，费用低。手术技巧的提高可避免或减少术中术后并发症。

血管紧张素转换酶2与糖尿病肾病

The identification of angiotensin-converting enzyme (ACE)2 opened new recognition of renin-angiotensin system (RAS). ACE2 degrades Ang Ⅱ to Ang (1-7), maintains homeostasis of RAS with ACE. Studies have revealed that ACE2 has important functions in diabetic nephropathy. It may be a target for drug and is used as gene therapy for diabetic nephropathy. Amplifying ACE2 activity may have a potential therapeutic role for diabetic nephropathy.     

8年间剖宫产率及指证变化的临床分析

近年来，我国各地的剖宫产率均呈明显的上升趋势，部分地区的剖宫产率甚至高达60％。居高不下的剖宫产率已引起了广大产科工作者和全社会的广泛关注。对我院近8年来剖宫产病例的临床资料进行回顾性分析，以寻求剖宫产率逐年上升的原因及探讨降低剖宫产率的途径与方法。     

The radial forearm flap

Described in 1981 by the Chinese authors Yang Kuofan et al. [1] as a free flap, then in 1982 by Lu et al. [2] as a retrograde flow pedicle flap, this fasciocutaneous flap is designed at the level of the anterior and external faces of the forearm, and vascularized by the radial artery via a network of septal arteries. Prior to utilization it must be reversed on its distal pedicle. This flap allows repairing cutaneous substance loss of the whole hand and fingers. The emergence of the Chinese flap in the 1980’s resulted in a regression of the Mac Gregor groin flap that was widely used at this time [3,4]. Nevertheless, other forearm flaps, less “expensive” in terms of vascular involvement [5–9] have reduced its indications. The Chinese flap however keeps two essential indications: the multi-finger important defect that no other forearmflapmay cover; and composite substance loss of the thumb (despite the fact that the Chinese flap shares these indications with interosseous artery composite flaps).
