Objective To determine whether the maternal serum interleukin-6(IL-6)and in- terleukin-8(IL-8)concentrations can be used in the antenatal diagnosis of intrauterine infection in premature rupture of membranes(PROM).Methods The level of maternal serum IL-6 and IL-8 were determined by a sensitive enzyme-linked immunosorbent assays in 50 normal late pregnant women,25 patients with PROM but without evidence of IAI and 49 patients with PROM and IAI. Results The maternal serum IL-6 and IL-8 concentrations in patients with PROM and IAI were 301.19?142.34/L and 312.32?149.56 ng/L,which were higher than that in patients with PROM but without IAI(133.22?55.26 ng/L and 125.35?61.30 ng/L)and the normal late pregnant wom- en were(126.59?57.12 ng/L and 112.69?56.02 ng/L),P

Objective To formulate the quality standard of Rukang Capsule. Method The TLC of Zhebeimu, Xuanshen, Ruxiang and Tiandong were done separately. The HPLC-ELSD was used to determine the content of Astragaloside in Mongolian Milkretch Root. Result There were the same spots between the controls and samples and an excellent linear relationship for 1.44~4.32 ?g to the content determination of Astragaloside. The average recovery can reach 100.3% with 0.5% of RSD. Conclusion This method is reliable and accurate to application, and can be used for the quality control of the preperation.

To detect the soluble Fas (sFas) receptor level in sera from patients with myelodysplastic syndrome (MDS) and acute leukemia (AL), and investigate its clinical significance, the levels of sFas receptor in sera from 18 patients with MDS and 42 patients with AL were detected by using ELISA methods. The results suggested that the sFas receptor levels in sera from patients with MDS-RA were significantly lower than that from normal control (2.89?1.72 ng/ml vs 6.29?1.07 ng/ml, P

Objective To investigate therapeutic mechanism of radiation therapy associated with Doeetaxel on human uterine cervi-cal carcinoma. Method Hela cells were incubated with 0. 5 μmol/L, 1.01 μmol/Docetaxel for 24 hours, and were radiated with 0, 2, 4, 6, 8Gy X ray. The proliferation activity was detected with MTT method. Apoptosis was evaluated with TUNEL method. Expression of caspase-3 protein and the degradation fragment was measured with Western blot. Result Inhibitory effect of radiation therapy associated Docetaxel on Hela cells was significantly stronger than that of radiation group. Treated with 2 Gy and 6MV X ray radiation, inhibitory rate of Hela cells increased with the increment of associated Docetaxel doses (P<0.05). Inhibitory rate of Hela cells in radiation associated Docetaxel group was significantly increased compared with radiation group. Apoptosis index in radiation associated Docetaxel group 48 hours after treatment was significantly increased compared with radiation group or Docetaxel group with TUNEL method (P<0.05). Western blot results indies-ted that caspase-3 protein was degraded and small active fragments were produced. Conclusion The reason that Docetaxel enhanced Hela cell radiation sensitivity may probably he correlated to easpase-3 protein activation.

Objective: Docetaxel as a newly semi-synthesized anti-tumor drug,exhibits significant cyrotoxic activity and enhanced sensitivity for radiotherapy.The aim of this study was to investigate the correlation of the apoptosis of human Hela cell line with the expressions of TRAIL and its receptors induced by the combination therapy of Docetaxel with radiation.Methods: We treated the Hela line by Docetaxel,radiation,and combination therapy of Docetaxel with radiation,respectively,detected the apoptosis of the Hela cells using Hoechst 33342 staining and the TUNEL method,and observed the changes in the mRNA expressions of TRAIL and its receptors TRAIL-R in the three groups by RT-PCR.Results: Compared with the Docetaxel and the radiation groups,the apoptosis of the Hela cells was increased significantly in the combination therapy group,and so were the mRNA expressions of TRAIL and its receptors TRIAL-R1 and TRAIL-R2.Conclusion: The combination therapy of Docetaxel with radiation increased the apoptosis of the Hela cell line,which might be mediated by the up-regulation of mRNA expressions of TRAIL and its receptors TRAIL-R1 and TRAIL-R2.

OBJECTIVE:To prepare Puerarin polymeric micelles and establish a method to determine its entrapment efficiency. METHODS:Puerarin polymeric micelles were prepared by film dispersion method. The polymeric micelles and free drug were sepa-rated by centrifugal-millipore filter filtration method. The entrapment efficiency of puerarin polymeric micelles was determined by HPLC. Diamonsil C18(2)column was used with 1% citric acid solution-methanol(65∶35)at the flow rate of 1 ml/min. The detec-tion wavelength was set at 250 nm,and column temperature was room temperature. RESULTS:The prepared polymeric micelles were spherical and spherical-like in shape with a mean particle size of 54.12 nm,polydispersity index of 0.122,Zeta potential of -13.60 mV;the linear range of puerarin was 2-10μg/ml(R2=0.999 4)with average recovery rate of 99.2%(RSD=0.9%,n=3). The re-covery rate of free drug was 95.3%(RSD=1.7%,n=3). The mean entrapment efficiency and drug-loading amount of puerarin were(35.5±2.12)% and(0.3±0.07)%,respectively(n=3). CONCLUSIONS:Film dispersion method is suitable for the prepara-tion of Puerarin polymeric micelles. Established method is convenient,accurate and reliable for the content and entrapment efficien-cy determination of Puerarin polymeric micelles.

Aim To establish an allogenetic mouse skin trans-plant model,in order to provide a research model for immunosup-pressive drugs. Methods Skins from the ears of C57BL/6 mice were transplanted to the back of BALB/c mice and skin isografts ( BALB/c mice to BALB/c mice) were used as control. Cyclos-porin A( CsA) was used as a model compound to test the imm-nosuppresive effect on allogenetic graft rejection. Following the transplation and CsA treatment, the graft rejection score and graft skin survival rate were quantified. Four and nine days after transplantation,serum IL-4,IL-12 and IFN-γ levels were meas-ured using ELISA kits. Twelve days after transplantation, mice were sacrificed. The weight of spleen and thymus was obtained, and CD4 + and CD8 + population of spleenic T cells were ana-lyzed using flow cytometer. Histological features were assessed by hematoxylin-eosin( HE) staining of formalin-fixed, paraffin-em-bedded graft skins. Results After transplantion, the graft rejec-tion score increased and graft skin survival rate decreased gradu-allly. Serum IL-12 and IFN-γ levels of allograft mice increased markedly. Compared with those of isograft mice, mice with skin allograft displayed a significant increase in the percentage of the CD8 + T cell subpopulation. Remarkable inflammation, such as edema, inflammatory cell infiltration were observed in allograft mice. Compared with saline treated mice, CsA significantly re-duced the graft rejection score and improved survival rate of skin grafts. And also, CsA treated mice had smaller spleen and thy-mus. Mice that received high doses of CsA had significantly less CD8 + T cells than those treated with saline. Moreover, allograft skins in mice that received CsA had less inflammation. Conclu-sions Allogenetic mouse skin transplantation exhibits acute graft rejection. CsA can inhibit the rejection in a dose dependent manner.
