Objective To observe the clinical effect of gifitinib combined with hydroxylcamptothecin pericardial perfusion in the treatment of patients with advanced non-small cell lung cancer(NSCLC) with pericardial effusion. Methods From January 2016 to September 2017,eighty-four cases of late NSCLC with pericardial effusion treated in the People′s Hospital of Jiaozhou were randomly divided into two groups according to the digital table,with 42 cases in each group.The control group was treated with gefitinib,and the observation group was treated with hydroxylcampto-thecin on the basis of the control group.The curative effect was evaluated after two courses of treatment in the two groups,and the clinical efficacy and adverse reactions were observed.Results The effective rates of the control group and the observation group were 47.6% (20/42) and 66.7% (28/42),respectively.The effective rate of the observa-tion group was significantly higher than that of the control group(χ2 =4.525,P<0.05).The effective rate of pericar-dial effusion was 33.3% (14/42) in the control group and 69.1% (29/42) in the observation group,the difference between the two groups was statistically significant( χ2 =10.720,P <0.05).There was no ststistically significant difference in the incidence rate of adverse reactions between the two groups during treatment(P<0.05).Conclusion Combination of gefitinib and hydroxylcamptothecin pericardial perfusion in the treatment of NSCLC with pericardial effusion has good tolerance and good safety for the patients.

Dioscin chemical compositions are the main effective components in clinical commonly used Chinese medicines such as Diaoxinxuekang capsules and Xinnaoshutong capsules etc , which show distinct curative effect on cardiovascular and cerebrovascular diseases.Meanwhile, they are the important raw materials for the synthesis of steroid hormone drugs .The studies on the extraction technology exhibit important significance in the exploration of pharmacological activities of the components , which also are the external requirements for the growing demand of steroid hormone drugs market .In this paper , the relatively mature extraction methods re-searched in recent years were summarized ,and the advantages and disadvantages of the different processes were discussed in order to provide reference for the further studies and application .

Objective: To optimize the alcohol concentration for Jinyin Qingre oral liquids extracted by semi-bionic extraction (SBE). Methods:Using proportional division method to set up 5 alcohol concentration 30%,55%,61. 25%,67. 5%,80% for the ex-periment . The dried extract yield and the contents of chlorogenic acid ,geniposide,salviandic acid B and total phenolic acid were set up as indexes which were standardized as the comprehensive evaluation value ( Y) ,using the weighting coefficient had been set. Choosing the appropriate concentration by comparing the value of Y. Results:The order of comprehensive evaluation value was as follows:30%>61. 25% >55% >80% >67. 5%. Conclusion:Combining the clarity of the oral liquids, the best alcohol concentration in SBE for Jinyin Qingre oral liquids is 61. 25%.
