抓住机遇构建和谐发展的疾病防控体系

近几年，国家加强了对突发公共卫生事件应急反应能力的要求，人民群众的防病意识不断增强，疾病控制中心传统工作模式受到了极大挑战。吉林省疾病预防控制中心作为省直卫生系统人事制度改革试点单位，于2003年11月初开始，历经2个月时间圆满完成了单位人事制度与分配制度改革工作，取得了令人满意的效果。现将我们的做法与体会总结如下。     

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.     

Radiographic manifestations and pathologic basis of parosteal osteosarcoma. Analysis of 17 cases.

The authors reviewed the radiographic manifestations of 17 cases of parosteal osteosarcoma, with pathologic correlation in 15. There were two types of parosteal osteosarcoma radiologically. The majority of cases were type I with uniformly dense masses which had regular borders. They often adhered to the cortex and showed no evidence of soft-tissue invasion which correlated with low-grade pathologic malignancy and a relatively benign clinical course. Type II involved the bone, soft-tissue and the medullary cavity. These lesions were poorly differentiated and frequently accompanied by metastatic lesions.

     

The influence of some non-steroidal anti-inflammatory drugs on the retraction of collagen lattices.

The effects of some antirheumatics on the formation and retraction of collagen lattices seeded with fibroblasts have been studied. Among the antirheumatics, diclofenac was the most active inhibitor of lattice retraction, then tropesin and to a lesser extent indomethacin. Ibuprofen which is known as a very slight inhibitor of protein synthesis was able to significantly enhance lattice retraction when 10 micrograms/ml (48.5 microM) and 50 micrograms/ml (242 microM) were used.     

脊柱侧凸翻修手术

目的探讨脊柱侧凸手术失败原因及翻修手术的处理方法。方法回顾性分析我院自1997年以来收治的脊柱侧凸矫形术后需要进行翻修手术患者33例。男10例，女23例。翻修时距初次手术时间平均为13．4个月(0．5．66个月)。33例患者共行43次翻修手术，其中29例进行1次翻修手术，2例进行3次翻修手术，2例进行4次翻修手术。另有4例患者增加脊柱矫形和融合，同时行脊柱前路松解、支撑植骨手术。结果翻修手术时间平均3．9h(1．5—7．3h)，手术中平均出血601ml(50—2000ml)，平均输血量643．3mk(0-2000ml)。术后随访平均27个月(3—67个月)，未出现畸形加重、内固定失败等并发症。结论脊柱侧凸翻修手术是脊柱畸形矫形术后的一种补救手术。术前完善的手术策略和良好的手术技术是翻修手术的关键。     

子宫动脉栓塞治疗子宫肌瘤89例报告

目的 评价子宫动脉栓塞术治疗子宫肌瘤的近期疗效。方法 89例子宫肌瘤患者，采用Seldinger技术分别作左右子宫动脉主干插管检查和栓塞治疗，栓塞剂采用聚乙稀醇颗粒(PVA)或白芨混合颗粒。结果 72例(80．9％)完成随访，随访时间1～28个月。有94．1％(64／68)的患者月经复常；治疗后瘤体缩小25．2％～76．8％(M=41．3％)。除了术中术后疼痛(65例)和发热(16例)外，有2例因肌瘤坏死行子宫切除术，1例出现卵巢早衰。结论 子宫动脉栓塞术治疗子宫肌瘤的近期疗效满意，远期疗效尚待进一步观察。     

上胸椎骨折手术治疗方法的探讨

目的 探讨上胸椎骨折的特点及治疗。方法 15例病人按AO分型，A型2例、B型10例、C型3例。均经后路切开复位、脊髓减压、长节段内固定、取髂骨植骨融合术治疗。结果 随访18-24个月，后路长节段固定随访时无一例失败，完全瘫的患者9例中有1例神经功能改善I级．不完全瘫的5例均有Ⅲ级改善，1例无神经损伤。结论 上胸椎骨折损伤严重，后路长节段固定技术是一种合理的有效治疗方法。
