Objective To explore the incidence and risk factors of perioperative major adverse cardiac events (MACE) in lung cancer patients with high-risk coronary heart disease undergoing pulmonary lobectomy. Methods The clinical dataof 1 647 high-risk coronary heart disease patients diagnosed with lung cancer undergoing lobectomy in our hospital was analyzed, and performed Framingham scoring. High-risk patients (score> 20%) were included in the study, and the periopertive major adverse cardiac events was defined as primary endpoint. The risk factors of MACE were analyzed. Results Perioperative MACE occurred in 26. 4% of lung cancer patients with high-risk coronary heart disease undergoing lobectomy. Multivariate analysis demonstrated that hypertension, high density lipoprotein (HDL-C), diabetes, age, coronary angiography, stroke, smoking index in descending sequence were independent risk factors of perioperative cardiac events in lung cancer patients. While shorter operative time, coronary angiography and clinical intervention was protective factor. Conclusion Lung cancer patients with high-risk coronary heart disease undergoing lobectomy has higher risk of perioperative MACE. Preoperative sufficient cardiac risk scores, coronary angiography andclinical interventioncan reduce the incidence of perioperative MACE in lung cancer patients with high-risk coronary heart disease.

Objective To adopt the capillary electrophoresis(HPCE) for detecting the contents of emodin,chrysophanol and rhein in the extract of rheum officinale.Methods The detection was executed with a fused-silica capillary column(67.4 cm× 75.0 μm,effective length 51.0cm) as the separation column.The buffer solution consisted of 60 mmol/L Na2B4O7,40 mmol/L Na2CO3 and 40 mmol β-cyclodextrin(pH 8.9).The detection wavelength was 254 nm.Results RSD of precision in emodin,chrysophanol and rhein was 1.79%,4.46% and 2.30%.respectively The linear range of 3 components was 1.1-19.0 mg/mL;the average recovery rates of emodin,chrysophanol and rhein were 100.14 %,99.65 % and 98.44 % respectively,RSD was 2.43 %,2.54 % and 2.02% respectively(n=3).Conclusion The method can be used in the content determination of rheum officinale extract.
