目的 測(cè)定多發(fā)性骨髓瘤(MM)患者血清胱抑素C (Cys-C) 的水平,探討Cys-C與國際分期體系(ISS)、血β2-微球蛋白、溶骨性損害等指標(biāo)的關(guān)系。 方法 收集2008年1月-2010年9月32例初治和8例復(fù)發(fā)的MM患者作為研究對(duì)象,同時(shí)收集40例健康體檢者的檢查資料作為對(duì)照組,測(cè)定血清Cys-C、血肌酐(Scr)、血β2-微球蛋白。采用核素全身骨顯像(ECT)觀察患者的溶骨性病變部位數(shù)。 結(jié)果 患者血清Cys-C水平(1.40 mg/L)明顯高于健康對(duì)照組(0.90 mg/L)(P<0.01);在MM患者中Cys-C比Scr更敏感,能反映腎小球?yàn)V過率;血清Cys-C水平與ISS分期晚,血β2-微球蛋白升高以及溶骨性病變進(jìn)展密切相關(guān)。 結(jié)論 MM患者的Cys-C水平高于健康者。Cys-C是骨髓瘤腎損害的早期敏感標(biāo)志物,與腫瘤負(fù)荷及溶骨性損害密切相關(guān),可作為評(píng)價(jià)腫瘤負(fù)荷的潛在指標(biāo)。Objective To evaluate the serum levels of cystatin-C in patients with multiple myeloma (MM), and to explore its possible correlations with clinical data, including ISS stage, serum β2-microglobulin, and advanced lytic lesions. Methods From January 2008 to September 2010, serum cystatin-C, creatinine (Scr), and β2-microglobulin in 32 patients with MM, 8 patients with relapsed disease, and in 40 healthy controls were detected by automatic biochemistry analyzer detection. According to skeleton ECT, grading of osteolytic lesion was observed. Results The levels of serum cystatin-C of patients with MM were significantly higher than those of the controls. Serum cystatin-C could reflect the glomerular filtration rate , and was more sensitive than Scr in patients with renal lesion. Serum cystatin-C had ber correlations with advanced ISS stages, high levels of serum β2-microglobulin, and extensive bone diseases. Conclusion Serum cystatin-C is a sensitive marker of renal lesion in patients with MM, it could be a potential indicator to assess the tumor burden.
目的 總結(jié)采用改良帶蒂(足母)展肌肌皮瓣移位修復(fù)足跟部皮膚惡性黑色素瘤擴(kuò)大切除后軟組織缺損的療效。方法 2008年2月-2011年6月,收治5例足跟部皮膚惡性黑色素瘤患者。男2例,女3例;年齡35~69歲,平均49歲。病程2~10年。足跟原發(fā)腫瘤范圍為3 cm × 2 cm~5 cm × 4 cm,3例伴破潰。4例腫瘤擴(kuò)大切除后缺損范圍為6 cm × 6 cm~8 cm × 6 cm,1例因伴衛(wèi)星灶缺損達(dá)13 cm × 12 cm;采用大小為6 cm × 6 cm~11 cm × 9 cm改良帶蒂(足母)展肌肌皮瓣移位修復(fù)缺損,不足部分取中厚皮片修復(fù)。供區(qū)采用腹股溝中厚皮片修復(fù)。 結(jié)果術(shù)后肌皮瓣及供受區(qū)植皮均成活,創(chuàng)面Ⅰ期愈合。2例腹股溝切口發(fā)生淋巴漏,經(jīng)換藥和清創(chuàng)術(shù)后愈合。5例均獲隨訪,隨訪時(shí)間12~24個(gè)月。足跟部皮膚無破裂和磨損,外形豐滿、彈性良好,肌皮瓣痛、溫覺和耐磨性能良好。足踝伸屈功能正常,恢復(fù)負(fù)重功能,無腫瘤生長(zhǎng)。足部切取肌皮瓣處凹陷明顯,第1、2、3趾底感覺減退、麻木。 結(jié)論改良帶蒂(足母)展肌肌皮瓣修復(fù)足跟部皮膚惡性黑色素瘤切除后缺損可獲得豐滿、耐磨和彈性好的外觀。
