医疗卫生服务价格改革方向初探

医疗卫生服务价格改革是要理顺价格构成成份之间量的关系，使每个构成成份的价格值都在供求关系的约束中，在政府的有效管制中，从而成为医疗卫生资源合理配置的有效工具。为此：①对生产要素分别定价；②对劳动定价；③对资本和自然资源定价；④确定医疗卫生机构内部管理时劳动价格；⑤价格中的所有构成成份价格都置于供给和需求关系约束下；⑥确定医疗卫生服务价格的理想传递方式。     

Richard钉治疗股骨粗隆间骨折

目的：报告在不使用C型臂X线机的情况下，应用Richard钉治疗股骨粗隆间骨折经验，并对治疗结果进行评估。方法：33例股骨粗隆间骨折均采作一次摄片导针定位行Richard钉内固定手术。结果：33例随访6月-3年骨折全部愈合，无螺钉穿破股骨头，无钉板、螺钉断裂。无螺钉退出，无骨折畸形愈合，3例行走活动时有轻微疼痛，全部病例均无髋关节活动受限。结论：该方法定位准确、操作方便、固定可靠、允许早期活动、功能恢复快、并发症少，特别适合无C型臂X线机的基层医院推广应用。

小腿后侧逆行血管筋膜蒂皮瓣修复小腿软组织缺损

小腿软组织缺损的修复是骨科领域的一大难题,目前方法很多,效果不一。我科自1990年7月至2000年4月,应用小腿后侧逆行筋膜血管蒂皮瓣,修复小腿软组织缺损8例,获得良好的临床效果。1临床资料1.1一般资料:8例患者中,男性6例,女性2例,年龄21～45岁,平均31.5岁。部位:小腿下端前侧4例,足跟部2例,外踝处2例。病因:分明伤性软组织缺损伴骨处露7例,其中3例合并骨折,1例合并骨髓炎,另1例为跟腱外露,皮瓣面积最大15×12cm,最小7cm×4cm。1.2手术方法:以窝中心与腓骨头连线的中点为起点,内外踝连线中点上方5cm为止点,连续即为皮瓣的轴心线。并以内外踝…     

Analysis of differentially expressed genes in fetal skin of scarless and scar-forming periods of gestational rats

Objective: To study the differences of gene expression between earlier gestational skin and later gestational skin of rats with the aids of single primer amplification (SPA) and high-density oligonucleotide DNA array to understand the molecular mechanism of scarless healing. Methods: Total RNAs were isolated from fetal rat skin of the scarless (E15) and scar-forming (E18) periods of gestation (term =21.5 days). The RNAs from earlier gestational skin (EGS) and later gestational skin (LGS) were both reversely transcribed to cDNAs, then labeled with the incorporation of fluorescent dCTP for preparing the hybridization probes by SPA method. The mixed probes were then hybridized to the oligonucleotide DNA arrays which contained 5 705 probes representing 5 705 rat genes. After highly stringent washing, these DNA arrays were scanned for fluorescent signals to display the differentially expressed genes between the 2 groups of skin. Results: Among 5 705 rat genes, there were 53 genes (0.93%) with differentially expressed levels between EGS and LGS groups, 27 genes, including fibroblast growth factor 2 ( FGF2 ) and follistatin were up-regulated (0.47%) and 26 genes were down-regulated (0.46%) in fetal skin during scarless period versus scar-forming period. Higher expressions of FGF2 and follistatin in EGS than those in LGS were also revealed by RT-PCR method. Conclusions: High-density oligonucleotide DNA array provided a powerful tool for investigating differential gene expression in earlier and later gestational fetal skins. This technology validates that the mechanism of fetal scarless healing is very complicate and the change of many gene expressions is associated with fetal scarless healing.
