Objective To discuss the key points of nursing care for patients using ultrasound-guided microwave coagulation therapy with artificial pleural effusion for liver carcinoma in the hepatic dome.Methods The preoperative and postoperative data of 34 patients who were hospitalized in our hospital from June 2004 to February 2009 were reviewed.Results All the patients finished the treatment successfully.Slightly chest distress was the most frequently complication correlated to artificial pleural effusion,mostly disappeared in 3-7 days.Only 3 patients suffered from dyspnea and a decrease of SpO_2 in the second day after the treatment.The symptoms were relieved after a drainage of pleural.The common side effects of microwave coagulation therapy were found as fever,pain during deep respiration and liver dysfunction,which were relieved after symptomatic treatment and nursing care.No severe complication was found.Conclusions Adequate preoperative preparation,proper intraoperative cooperation,close postoperative observation and nursing are the key points to decrease complications.

Objective To determinate the contents of α-pinene, β-pinene, eucalyptol and linalool in Baeckea frutescens by reference substances method and reference extract method respectively; To explore the feasibility of replacing single component reference by control extracts in assay. Methods The GC system consisted of a quartz column DB-5 (60 m×0.25 mm×0.25 μm); The temperature programming rose from 80 ℃ (15 min) to 90 ℃ by 1 ℃/min, lasting 2 min, then 10 ℃/min to 110 ℃, then 25 ℃/min to 240 ℃, lasting 8 min in the end; The temperature of the entrance of capillary vessel column was 250 ℃, and the temperature of the detector was 250 ℃. Results α-pinene, β-pinene, eucalyptol and linalool were in a good linear relationship within each concentration scope (r≥0.999). The average recovery rates were in the range of 96.5%–102.2%. The results of t-test demonstrated that there is no significant difference between the two methods. Conclusion The reference extract method can be used as a quality evaluation pattern for Baeckea frutescens.
