Objective To observe the clinical curative effect of Bushen Tiaochong method on treating early unexplained recurrent spontaneous abortion (URSA). Methods 200 patients who conformed to the inclusion criteria were randomly and paralleled control study divided into two groups.The control group (routine tocolysis group,n =100 ),with 8 cases fell off. The experimental group (routine tocolysis group +traditional Chinese medicine group,n =100 ),with 10 cases fell off. Results After the treatment,the total efficiency of the control group was 70.65%,and the experimental group was 88.89%. The total efficiency of comparative difference was statistically significant (p<0.05 ). And compared the experimental group with the control group,the former group improved the level of human chorionic gonadotropin(HCG)in patients. Conclusion Bushen Tiaochong method with traditional Chinese medicine combined western medicine treatment can significantly improve the symptoms of URSA patients with threatened abortion. Compared with simple western medicine therapy,the former group has better curative effect on early unexplained recurrent spontaneous abortion.

This study was aimed to investigate the effect of modifiedYin-Chen-Hao (YCH) decoction on the expression of aquaporin-8 (AQP8) mRNA and protein in rats with estrogen-induced cholestasis, in order to explore the potential mechanism of YCH decoction in the treatment of intrahepatic cholestasis during pregnancy. A total of 50 SD female rats, which were weighed between 180 g to 200 g, were randomly divided into the normal group (N,n = 10) and the model group (M’,n = 40). The animal model of intrahepatic cholestasis was induced by subcutaneous injection of 17-α-ethinylestradiol (5 mg·kg-1·d-1) for 5 days of rats in M’ group. The same volume of propylene glycol was subcutaneously injected to rats in N group. Five days later, rats in M’ group were divided into the model group (M,n = 10), high-dose (Zg,n = 10), middle-dose (Zz,n = 10) and low-dose (Zd,n = 10) modified YCH decoction group. The intragastric administration of normal saline, high-dose, middle-dose and low-dose modified YCH decoction were given to each group for 7 days, respectively. Then, rats were sacrificed and the liver tissues were removed and stored in liquid nitrogen. The expression of AQP8 mRNA and protein were detected by real-time polymerase chain reaction (RT-PCR) and western blotting analysis. The results showed that compared with the normal group (N), the expression of AQP8 mRNA and protein in liver tissues of rats in the model group (M) were decreased (P < 0.01). Compared with the model group (M), the high-dose, middle-dose and low-dose modified YCH decoction can increase the expression of AQP8 mRNA and protein in liver tissues (P < 0.05). Moreover, along with the dose increasing of modified YCH decoction, the upregulation of AQP8 mRNA and protein was increased. It was concluded that the molecular mechanism of modified YCH decoction in treatment of intrahepatic cholestasis during pregnancy may be through the increasing of AQP8 mRNA and protein in liver tissues.

Logistics supplies are essential for normal operations of hospitals,while effective management of hospital suppliers is key to optimizing the materials supplies.An evaluation system is built for both key suppliers and standby suppliers respectively.Based on such a system,a dynamic management mechanism is built to provide long-lasting supplier incentives,for competitive selection and elimination of the suppliers.These efforts enable the hospitals to pick the best suppliers by means of systems and regulations.

Treatment with the combination of Chinese herbs and cytotoxic chemotherapies showed a higher survival rate in clinical trials. In this report, the results demonstrated that the tanshinone II A, a key component of Salvia miltiorrhiza bunge, when it is combined with the cytotoxic drug cisplatin showed synergistic antitumor effects on human prostate cancer PC3 cells and LNCaP cells in vitro. Antiproliferative effects were detected with MTT assay. Cell cycle distribution and apoptosis were detected by flow cytometer. Protein expression was detected by Western blotting. The intracellular concentration of cisplatin was detected by high performance liquid chromatography. The results demonstrated that tanshinone II A significantly enhanced the antiproliferative effects of cisplatin on human prostate cancer PC3 cells and LNCaP cells with the increase of the intracellular concentration of cisplatin. These effects were correlated with cell cycle arrested at S phase and cell apoptosis. The apoptosis might be achieved through death receptor pathway and mitochondrial pathway. Furthermore, the Bcl-2 family members were also involved in this apoptotic process. Collectively, these results indicated that the combination of tanshinone II A and cisplatin had a better treatment effect in vitro not only on androgen-dependent LNCaP cells but also on androgen-independent PC3 cells.
