Objective To study the absorption and transport mechanism of ursolic acid(UA) by using Caco-2 monolayer model.Methods Evaluating the transport characteristic through studying whether P-glycoprotein(P-gp) transporter inhibitor Verapamil(VER) exists or not by using Caco-2 cell monolayer as an intestinal epithelial cell model and investigating the effects of uptake time,drug concentration,system temperature,and pH value of culture media on the uptake of UA.The drug concentration was measured by HPLC coupled with UV detector.Transport parameters and apparent permeability coefficients (P_(app)) were then calculated.Results In the concentration range of 10—40?mol/L,the uptake of UA by Caco-2 cell all linearly increased.The P_(app) of UA transported on Caco-2 cell monolayer model significantly changed when the specificity inhibitory of P-gp was added to model and the apparent permeability ratio decreased from 3.445 to 1.386.Conclusion The intestinal absorption of UA is passive diffusion as the dominating process and active transportation mediated by P-gp transporter in Caco-2 cell monolayer model.

Objective To study and analyze the clinical efficacy of massage combined with Astragalus and eucommia Decoction in the treatment of periarthritis of shoulder.Methods100 patients with periarthritis of shoulder treated in our hospital from July 2015 to July 2016 were selected.They were randomly divided into the control group and the experimental group, with 50 patients in each group.Patients in the control group were treated with massage, and the experimental group was treated with massage combined with astragalus root and Eucommia ulmoides decoction.The 2 groups were treated with 2 or two courses, the 1 course of treatment for 15 days.The treatment effect and relative shoulder index score of the experimental group and the control group were compared and analyzed.ResultsAfter the corresponding treatment, the effective number of patients in the experimental group was 48 cases.The effective rate of treatment was 96%.The number of effective cases in the control group was 44, and the effective rate was 88%.The effective rate of the experimental group was significantly higher than that of the controlgroup, with statistical difference (P<0.05).After treatment, the shoulder function, activity and pain in the experimental group and the control group were significantly better than those before the treatment,The scores of shoulder functional performance index and shoulder pain index in the experimental group were significantly lower than those in the control group, with statistical difference (P<0.05).ConclusionMassage combined with Huangqi Eucommia Decoction in the treatment of periarthritis of shoulder can improve the therapeutic effect to a great extent, reduce the pain of patients with shoulder joint, to help with the recovery of shoulder joint function, with further clinical promotion and application significance.

Objective To explore the absorption characteristics and mechanism of P-glycoprotein (P-gp) mediated transport of oleanolicacid (OA)across membrane in vitro.Methods The intake and transport of OA were evaluated by an HPLC/MS quantitative detection method.Safe concentration range of OA was determined by MTT.The effect of different drug concentration,incubation time,pH and temperature on the intake of OA by Caco-2 cells were investigated.The effect of P-gp inhibitor on the transmembrane transport of OA was investigated by the Caco-2 cell monolayer model,and the apparent permeability coefficient (Papp) was calculated.Results The uptake of O A was concentration-time dependent and correlated negatively to temperaturein Caco-2 cells within the safe concentration range,but was not significantly affected by pH value.Compared with controls,the Papp significantly changed when the P-gp inhibitor was added to the model(P ＜ 0.05).The apparent permeability ratio decreased from 2.90 to 0.95.Conclusion The absorption of OA was primarily by passive diffusion and might be mediated by the effiux by P-gp.

Objective To investigate the optimal gestational weight gain (GWG) in twin pregnancies and to analyze the impact of GWG on pregnant outcomes.Methods A retrospective cohort study of twin pregnancies was conducted on women who gave birth in International Peace Maternity and Child Health Hospital,Shanghai Jiaotong University School of Medicine from January 1,2012 to the June 30,2015.An optimal range of GWG was calculated based on the amount of weight gain in 711 subjects who gave birth to normal twins and with uncomplicated pregnancy.Another 504 twin pregnant women without gestational complications were recruited for further analysis of the relationship between GWG and gestational outcomes.T-test,analysis of variance and Chi-square test were used for statistical analysis.Results (1) The optimal range of GWG for full-term twin-pregnancy was 15.3-21.4 kg.In those with low body mass index (BMI,＜18.5),normal BMI (≥ 18.5-＜25.0) and overweight/obesity (≥ 25.0),the GWG [M(P25-P75)] were 18.5 (15.8-22.2),18.3 (15.3-21.3) and 18.1 (14.9-21.5) kg,respectively.There was no significant difference in GWG among those groups (F=0.121,P=0.886).(2) According to the optimal GWG mentioned above,we divided the 504 cases into three groups,including lower GWG group (less than the optimal GWG,n=137),normal GWG group (in the GWG range,n=238) and higher GWG group (more than the optimal GWG,n=129).The neonatal birth weights in the three groups were (2 626.1 ±225.8),(2 680.14-237.9) and (2 751.9±257.1) g (F=9.189,P＜0.01),respectively,indicating that neonatal birth weight was increased by increasing GWG.The proportion of both twins with birth weights of more than 2 500 g was slightly increased,but there was no significant difference among the three groups [51.1 ％ (70/137),60.5％ (144/238) and 64.3％ (83/129),respectively,x2=5.279,P=0.071].The incidence of gestational diabetes mellitus (GDM) was reduced along with increased GWG [31.4％ (43/137),14.7％ (35/238) and 9.3％ (12/129),respectively,x2=25.144,P＜0.01],while the incidence of hypertensive disorders in pregnancy (HDP,including gestational hypertension and preeclampsia) in the three groups showed no significant difference.There were 90 cases (17.8％) of GDM in the 504 cases with a pre-pregnancy BMI of 22.5±2.8,which was higher than that of the non-GDM cases (21.21±2.9),(t=3.735,P＜0.01).Among the 504 cases,there were 67 cases (13.3％) of HDP (including gestational hypertension and preeclampsia) with a pre-pregnancy BMI of 22.4±2.8,which was higher than that of the non-HDP patients (21.3 ± 2.9,t=2.767,P=0.006).Conclusions The pre-pregnancy BMI has little influence on GWG in twin pregnancies.Increasing GWG to the recommended optimal range or above,and within a certain range,could promote an increase in neonatal birth weight without adding the risks of gestational complications,such as gestational diabetes mellitus,gestational hypertension and preeclampsia.
