Association of the Platelet Glycoprotein Ⅰa C807T Gene Polymorphism With Risk of Myocardial Infarction in Chinese

Objectives To investigate the relationship of the GPIa C807T dimorphism to the risk of myocardial infarction (MI) in Chinese. Methods We did a case-control study including 100 patients and 110 controls with same race. An allele-specific polymerase chain reaction (PCR) was used for genotyping of C807T polymorphism. Results An apparent association was found between the T807 allele and MI among individuals younger than the mean age of 60 years (odds ratio,2.49; 95% confidence interval, 1.08 ～ 6.22 ). The T807 allele remained an independent risk factor for MI when age, sex, smoking, hypertension, diabetes, bodymass index, LDL-cholesterol and HDL-cholesterol were adjusted by logistic regression. Conclusions GPⅠa T807 appears to be an independent risk factor for MI.     

64排螺旋CT冠状动脉造影与DSA的对照研究

目的:通过和冠脉造影对比,评价64排螺旋CT冠状动脉成像在冠状动脉狭窄中的临床应用价值。方法:28例患者同时行64排螺旋CT冠状动脉成像和有创性冠脉造影检查,依据AHA17段分段法,评价所有有效节段,并将两者进行对比。结果:冠脉造影显示阴性病例占7.1%(2例),单只病变占21.4%(6例),多支病变占71.4%(20例)。按节段分析,CT检出冠脉狭窄的敏感度,特异度,阳性预测值和阴性预测值分别为91.1%,94.6%,90.0和95.3%。结论:64排螺旋CT冠状动脉成像和传统的冠脉造影检查对检出正常冠脉节段以及狭窄节段具有很好的一致性。     

PICC的X线分析

目的:旨在探索PICC末端位置的合理区间。方法:观察79例患者PICC末端位置、置管后的近、远期临床表现以及100例正常胸片肺门位置。结果:导管末端位于第一前肋端至右肺门上方时,少有不良反应。结论:导管末端位置以第一前肋端至右肺门上方为宜。     

慢性肝炎辨治五法

慢性肝炎（简称慢肝）属中医学“胁痛”、“黄疽”、“瘾积”等范畴。其病程长，疗效慢，且易反复发作。目前尚无特殊疗法。笔者通过研习有关文献，回顾长期临床验案，对慢性肝炎之证治略有心得，兹介绍如下。     

慢性鼻窦炎鼻息肉合并支气管哮喘患者鼻窦内镜术后对支气管哮喘疗效的影响

目的观察鼻窦内镜术(endoscopic sinu ssurgery，ESS)对慢性鼻窦炎伴支气管哮喘患者哮喘发作的影响。方法对210例慢性鼻窦炎患者施行ESS术，其中伴有支气管哮喘病史者42例(20．0％)。210例患者均于术前、术后采用酶联免疫吸附测定法(ELISA)检测外周血单个核细胞(PBMC)培养上清液中的白细胞介素4(IL-4)，干扰素γ(IFN-γ)，可溶性白细胞介素2受体(sIL-2R)和可溶性IgE低亲和力受体(solube CD23，sCD23)的含量，并与20例正常对照组进行比较。通过主观和客观标准评定42例患者哮喘发作及对皮质类固醇的耐受状况，并对术后患者进行为期1年(10例)和3年(32例)的随访。结果鼻窦炎合并支气管哮喘患者术前PBMC培养上清液中IL-4，sIL-2R、sCD23含量较对照组显著升高，而IFN-γ含量较对照组显著减少。术后IL-4、sIL-2R、sCD23含量较对照组显著降低，而IFN-γ含量显著增高。术后哮喘改善水平由随访术后1年的45％提高到术后3年的70％。42例中32例(76％)哮喘发作次数明显减少，术前长期服用类固醇的2l例中，14例(67％)减少了对口服类固醇的使用。结论ESS对慢性鼻窦炎伴支气管哮喘患者的治疗有较满意的远期疗效。ESS能调节IL-4、IFN-γ sIL-2R、sCD23水平，降低哮喘的发作频率和对类固醇的依赖。     

Does the Suggested Lightwand Bent Length Fit Every Patient?: The Relation between Bent Length and Patient's Thyroid Prominence-to-Mandibular Angle Distance

Background: To date, no study has explored the effect of bent length on lightwand intubation. For successful intubation in daily practice, the authors found that bent length should be approximated to the patient's thyroid prominence-to-mandibular angle distance (TMD), but some patients have a TMD much shorter than the suggested bent length range. The purposes of this study were to understand TMD distribution in adults and to test the influence of bent length on lightwand intubation.

Methods: The TMD, airway, and demographic data of 379 patients were collected. To test the bent length influence, patients were enrolled in group A (158 patients, TMD <= 5.5 cm) and group B (131 patients, TMD > 5.5 cm) and were intubated randomly using the lower (6.5 cm) and upper (8.5 cm) limits of the suggested range. Success rate and lightwand search time were compared.

Results: In group A, the success rate was 98.8% with 6.5-cm bent length and 78.2% with 8.5-cm bent length (P < 0.05). Search times were 5.7 +/- 2.90 and 8.9 +/- 5.80 s with 6.5- and 8.5-cm bent length, respectively (P < 0.01). In group B, there was no statistical difference in success rate and search time between 6.5- and 8.5-cm bent length.     

铁打的营盘VS流水的人才空军总医院的"激将法"

“铁打的营盘流水的兵”,到哪儿都是这个理。可当“铁打的营盘”遭遇“流水的人才”结果会怎样?曾几何时,一度人才防线牢不可破的公立医院,在面临外资和民营医疗机构强大的“挖角”攻势下,不得不仓促应战。虽然目前公立医院在这场人才拔河较量中仍具优势,只是不知这种优势还能维持多久?
