Objective To observe the effect of elemene injection for the maintenance treatment of malignant pleural effusion.Methods A total of 90 patients with malignant pleural effusion from May 2014 to Apirl 2016 in First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine were collected.They were divided into observation group (n =45) and control group (n =45) according to the random number table method.The patients of the two groups were treated with pleural effusion drainage through thoracocentesis,and Mannatide (Lifein) and carboplatin were poured.The observation group sequentially received maintenance treatment of elemene injection.The therapeutic effects of the two groups were compared.Results At the 12th month after treatment,the difference of relapse rate between the two groups was statistically significant(82.2% vs.100.0%,x2 =8.780,P =0.003).The median progression-free survival (95% CI) of the observation group and the control group were 10.00 (9.15-10.85) months and 6.00(4.74-7.26) months respectively,with a significant difference (x2 =40.475,P < 0.001).The improvement rates of life quality of the observation group were 82.22%,57.78%,54.55% respectively at one,six,twelve months after perfusion treatment,and the improvement rates of the control group were 84.44%,23.26%,0 respectively.The data differences between the two groups were statistically significant at six,twelve months (x2 =10.840,P =0.001;x2 =32.390,P < 0.001).The one year survival rates of the observation group and the control group were 97.78% and 95.56%,and the difference was statistically significant (P =1.000).Conclusion The effect of elemene injection for the maintenance treatment of malignant pleural effusion is obvious,which can prolong the progression-free survival time and can significantly improve the quality of life.

A method for the determination of caffeine in urea was developed based on bubble-in-drop single drop microextraction (BID-SDME) followed by gas chromatography/mass spectrometry (GC-MS).Under the optimum conditions including chloroform as extraction solvent, an exposure volume of 1 μL, a bubble volume of 1.6 μL, stirring for 5 min at 300 r/min, 15% (m/V) NaCl, and a distance of 1 cm between bubble and stirring bar, the detection limit of this method was as low as 0.003 mg/L and the linear range was from 0.005 mg/L to 10 mg/L with correlation coefficient of 0.982.The recoveries of caffeine were from 89.2% to 107.5% at different spiked levels in human urine and the relative standard deviation (RSD, n=6) was less than 8%.

OBJECTIVE:To observe clinical efficacy and safety of Xiaoaiping injection with rectum administration combined with conventional chemotherapy in the treatment of epithelial ovarian tumor. METHODS:60 patients diagnosed as epithelial ovari-an tumor were divided into observation group and control group according to the actual order,with 30 cases in each group. AU pa-tients received TC chemotherapy,4-6 cycles in total;And patients in control group received TC chemotherapy for 3 weeks,i.e. pa-clitaxel 175 mg/m2,3 h,i.v.+carboplatin AUC=5-7.5,1 h,i.v.. Based on this,observation group was additionally given Xiaoaip-ing injection with rectum administration,20-30 ml each time,once a day,2 weeks as a treatment course. Clinical effective rate, 1-year progression-free survival rate and median progression free survival and the incidence of adverse events were compared be-tween 2 groups. RESULTS:Effective rate of observation group was 83.33%,and higher than that of control group (53.33%);there was statistically significant difference (χ2=13.20,P<0.05);1-year progression-free survival rate of observation group was 86.67%,and median progression free survival was 11.3 months;those of control group were 63.33% and 7.2 months;there was statistically significant difference between 2 groups (P<0.01 or P<0.05). There was no significant difference in the incidence of ADR between 2 groups(χ2=0.53,P=0.47). CONCLUSIONS:Xiaoaiping injection with rectum administration combined with con-ventional chemotherapy in the treatment of epithelial ovarian cancer show good curative effect and safety,high 1-year progres-sion-free survival rate and long median progression-free survival.

Objective To establish a method for determination of allicin(diallyl trisulfide) in the ultrafine garlic powder by gas chromatography(GC) . Methods Allicin injection was extracted by supersonic wave with a mixed solvent hexane-anhydrous ethanol(1:4) in GC by capillary column and detected by hydrogen flame ionization detector(FID) ,using nitrogen as the carrier gas. Results The peak areas were proportional to the allicin concentrations and the standard curve showed good linearity,y=190 282.5x-11 734.5(r=0.999 3) within the range of 0.30~3.00 mg/ml,the average recovery was 84.6%-98.6 % with RSD of 1.85%~3.27%. Conclusion The method is simple,accurate with good repeatability,and it is applicable to the determination of allicin in the ultrafine garlic powder.
