目的:觀察持續腹腔引流治療頑固性腹水的療效。方法:將頑固性腹水患者74例分為兩組,治療組38例,采用腹腔置管,持續腹腔引流腹水,3000mL/天;對照組36例,以常規補充白蛋白、限鈉、限水、利尿治療為主,比較兩組的療效。觀察治療組治療前后患者尿量、腹圍和體重變化,并比較治療組與對照組在肝、腎功能及電解質的變化及總體療效。結果:治療組療效優于對照組(Plt;0.05),與治療前比較,治療組治療后尿量、腹圍、體重有明顯改變(Plt;0.01), 肝、腎功能及電解質與對照組比較無明顯變化(Pgt;0.05)。結論:持續腹腔引流治療頑固性腹水經濟適用,不良反應少,患者依從性好。
Objective To investigate the detection of peritoneal free cancer cells and its clinical significance. Methods The peritoneal free cancer cells, the positive rates of CK20 protein and CK20 mRNA expressions of peritoneal lavage fluid were detected by peritoneal lavage cytology (PLC), flow cytometry (FCM) and real-time fluorescent quantitative RT-PCR in 50 cases of gastric cancer patients, respectively. The sensitivity of three kinds of detection method to peritoneal free cancer cells was compared. Results The positive rates of peritoneal free cancer cells, CK20 protein and mRNA expression of peritoneal lavage fluid were 20.0% (10/50), 36.0% (18/50) and 58.0% (29/50), respectively. The positive rate of CK20 mRNA expression detected by real-time fluorescencequantitative RT-PCR in peritoneal lavage fluid was significantly higher than those of the CK20 protein expression detected by FCM and peritoneal free cancer cells detected by PLC (Plt;0.05 or Plt;0.001). The difference of positive rate of CK20 protein expression and peritoneal free cancer cells was not significant (Pgt;0.05). The positive rate of CK20 mRNA expression of peritoneal lavage fluid was related to the tumor invasion depth, differentiation degree, TNM stage, and lymph node metastasis (Plt;0.05). Conclusion Real-time fluorescence quantitative RT-PCR is an effective method for the detection of peritoneal free cancer cells.
