Objective To observe the effects of compound Sophorae Flavescentis Radix (Kushen) Injection on immune function and quality of life in ovarian cancer patients with chemotherapy. Methods Sixty cases of ovarian cancer patients with chemotherapy were randomly divided into the observation group and the control group. Patients in the observation group were treated with paclitaxel plus carboplatin chemotherapy plus compoundKushen Injection for intravenous injection, while the patients in the control group were treated with paclitaxel plus carboplatin chemotherapy for three cycles. Changes in peripheral venous blood, the level of T cell subsets and NK cell, body weight, quality of life of 1 day before chemotherapy and 1 week after chemotherapy were observed.Results The mean values of CD3+, CD4+, CD4+/CD8+ and NK cells in the observation group improved to certain different degrees, with statistical significance compared with the control group (P<0.05). The body weight of observation group after chemotherapy increased than before chemotherapy (P<0.05);the control group had no significant difference (P>0.05). Karnofsky score of the observation group increased after chemotherapy (P<0.05);the control group had no obvious change (P>0.05).Conclusion CompoundKushen Injection can effectively enhance the immune function of ovarian cancer patients with chemotherapy, increase the weight of patients, and improve their quality of life.

A new aporphine alkaloid, named fuzitine, was isolated from the tuber of Aconitum carmichaeli Debx. Its chemical structure was identified by the chemical, UV, IR, MS and NMR spectra analysis.

Objective To study the relationship of expression of angiopoietin gene and angiogenesis in the in-situ implanted hepatoma in rats. Methods Forty Wistar rats were used to establish the in-situ implanted hepatoma model by implanting Walker256 hepatoma cell line. The number of microvessel density(MVD) in hepatoma was calculated . The expression of angiopoietin mRNA was observed by in-situ hybridization method. Results The MDV in the implanted hepatoma in the first day of 1, 2 and 3 week postimplantatively were (15?4.3)/Hp,(17?3.6)/Hp,(45?7.8)/Hp respectively. The amount of MDV and expression of Ang-1 mRNA were increased significantly and correlated with MDV in the hepatoma tissues and non-hepatoma tissues,and no significant difference between the two types of tissues. Expression of Ang-2 mRNA was not seen in non-hepatoma tissues,but in hepatoma tissues,the expression of Ang-2 was obvious. Conclusions Angiopoietin-2 mRNA may play a role in the angiogenesis of the in-situ implanted hepatoma.

OBJECTIVE:To extract,isolate the triterpenes from the leaves of Olea europaea,then conduct structural identifica-tion,and provide reference for development and application of the leaves of O. europaea. METHODS:Silica gel column and other methods were used for elution,column chromatography and recrystallization of the ethyl acetate part of ethanol extracts from the leaves of Olea europaea. The structures of separated compounds were identified by nuclear magnetic resonance. RESULTS:6 com-pounds were isolated from ethyl acetate part of the leaves of O. europaea,identified as β-amyrin,erythrodiol,2α,3β-dihydrox-yl-12-ursen-28-acid (compound 3),oleanolic acid,camaldulenic acid (compound 5),3α-maslinic acid. Compound 3 and com-pound 5 were isolated from the leaves of O. europaea for the first time. CONCLUSIONS:The study has provided test basis for the further development and reasonable application of the leaves of O. europaea.

Objective To discuss nicardipin′s influence on post operation cognitive dysfunction (POCD) in senior patient after hip joint replacement operation.Methods 180 senior patient, who received selective unilateral hip joint replacement operation between October 2015 and October 2016 under the condition of combined spinal-epidural anesthesia (CSEA) were randomly divided into Group A (with nicardipine) and Group B (without nicardipine).Nicardipine was only appropriately pumped into vein in time in Group A.MAP was observed and recorded 30 minutes after starting the operation and at the end of the operation.Mini-mental state examination (MMSE) was applied to score the patient one day before, one day, three days and five days after operation, and the number of POCD was recorded.Results Compared with Group B, Group A was obviously lower in MAP level (P<0.05) after 30 minutes.MMSE score of Group A was obviously higher (P<0.01) one day after operation.The number of POCD in Group A was 8 (8.89%) significantly lower than than that of Group B (19, 21.11%).Conclusion Nicardipine could maintain hemodynamic stability of senior patients receiving selective unilateral hip joint replacement operation under the CSEA and prevent POCD to a certain extent.
