The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

Background Some drugs with inhibitory effect on the proliferation of lens epithelial cells have a limiting application in clinic because of their adverse response.To screen the effective and less side-effect drug for supressing LECs growth is very inportant for the prevention and treatment of after cataract.Objective This study was to explore the effects of docetaxel on LECs growth and compare its role with epirubicin hydrochloride,pirarubicin hydrochloTide and rahitrexed.Methotis Immortalized human LECs line (SRA01/04) were cultured and passaged.Different concentrations of docetaxel,epirubicin hydrochloride,pirarubicin hydrochloride and rahitrexed were added into the medium respectively for 24.48 and 72 hours.The proliferation of LECs was detect by M1Yr.Flow cytometry analysis Was used to analyze the influence of different concentrations of docetaxel on cellular cycle at 48 hours after addition of docetaxel,and Annexin V-FITC/PI marking method was used to assesse the apoptosis of LECs under the action of docetaxel.Expression of bcl-2 protein in LECs Was evaluated by Westeru blot. Result The growth rate of LECs Wag 100%in 8-519 pmol/L doeetaxel groups with the normal cell shape.Majority of abnormal cells and low growth rate were found in 66 nmoVL docetaxel group at 48 and 72 hours.The IC50 of docetaxel was lowest in 48 and 72 hours in docetaxel group in comparison to epirubicin hydrochloride and pirarubicin hydrochloride. However,no evident inhibition on LECs growth in 23.22-523.56 μmol/L of raltitrexed.At 48 hours,the percentage of LECs in G2/M phase increased as the asccnte of concentration of docetaxel,showing a significant difference among 4 groups(F=2633.05,P＜0.01).The percentage of early apoptotic cells increased to 22.4%(χ2=20.00,P＜0.01) and 27.9%(χ2=42.68,P＜0.01)from normal control 3.1% at 48 hours after LECs exposed to 8.3 nmol/L and 266 nmol/L docetaxe.The expression of bcl-2 protein in LECs was obviously weakened after addition of docetaxel,especially 8.3 nmol/L docetaxel group. Conclusion Docetaxel,epirubicin hydrochloride and pirarubicin hydrochloride can inhibit the proliferation of human LECs in vitro.But there is no supression on LECs growth inraltitrexed.Docetaxel is proved to have a strongly arrested effect on the proliferation of LECs in comparison with epirubicin hydrochloride and pirarubicin hydrochloride and play its role at concentration-and time-dependent manner.

Objective To study the characteristics of the transcranial electric stimulation(TES)-elicited motor evoked potentials(MEP)recorded from different points of the diaphragm,and to determine the optimal record- ing site in the diaphragm.Methods One EEG electrode was placed subcutaneously in the midline of the skull as stimulation electrode and another EEG electrode was inserted into hard palate submucously as cathode in 30 male rats.And single square wave electrical pulse was used for stimulation.The stimulation intensity was 15 mA,the du- ration of the pulse was 0.2 ms,and the stimulating interval was 200 ms.The concentric needle electrode were insert- ed into the following eight sites:the medial,intermediate,lateral crura of the diaphragm,the junction of the posterior axilla line and the inferior border of the eleventh rib,the junction of the anterior axilla line and the inferior border of the ninth rib,the junction of the intermediate line of the clavicle and the inferior border of the eighth rib,the junction of the para-sternal line and the inferior border of the seventh rib,the pars sternalis.The MEP was recorded from each point,respectively.The optimal sites of the diaphragm MEP were found and recorded.Results The MEPs were re- corded from each of the 8 sites of the diaphragm in all the rats after TES.There was no statistically significant differ- ence among the latencies of every site.But the amplitude varied from 6.08?0.46 mV in maximum along the inferior border of the ninth rib at the anterior line of the axilla to the minimum of O.91?0.03 mV at the pars sternalis. Conclusion It is safer to insert the needle along the inferior border of the ninth rib at the anterior line of the axilla, because there was certain distant from the folding part of the pleura and the amplitude of the recorded wave at this point is maximal.

Objective To explore the therapeutic effect of combining continuous venovenous hemofiltration (CVVH) with hemoperfusion (HP) on patients with septic shock.Methods A prospective study was conducted. Thirty-two patients with septic shock admitted to Changshu No.1 People's Hospital were enrolled, and they were divided into two groups according to random digits table. The observation group (17 cases) was given HP before CVVH, in the control group (15 cases), only CVVH treatment was carried out, and lasting for 5 days in both groups. The changes of pulse oxygen saturation (SpO2), central venous pressure (CVP), systemic vascular resistance index (SVRI), cardiac index (CI), extra-vascular lung water index (EVLWI) were observed before treatment and 5 days after treatment.Results Compared with those before treatment, the levels of SpO2, CVP, SVRI, CI were obviously elevated, and EVLWI was markedly decreased after treatment in two groups. Compared with those of control group, the degrees of improvement of above indicators in observation group were more prominent [SpO2: 0.966±0.035 vs. 0.939±0.036, CVP (mmHg, 1 mmHg = 0.133 kPa): 8.5±3.2 vs. 8.1±4.2, SVRI (kPa·s·L-1·m-2): 1 497.35±157.08 vs. 1 343.60±144.48, CI (mL·s-1·m-2): 120.36±15.34 vs. 106.69±12.33, EVLWI (mL/kg): 6.84±0.73 vs. 7.65±0.70, allP < 0.05].Conclusion Combing HP with CVVH for treatment of patients with septic shock can improve their prognosis more obviously than using CVVH alone.

After studying the discipline of chemical components distribution in peony root, it was found that the content distribution of albiflorin, paeoniflorin, benzoylpaeoniflorin and paeonol was inhomogeneous in different parts of peony root, as same as in different roots belonging to a same plant. Therefore, in order to minimize the effects of different qualities of materials on experimental result, the content changing percentages of four chemical components was chosen as indicators to study processing method of Paeoniae Radix Alba. The processing technique of Paeoniae Radix Alba was put peony roots in the boiled water for at most ten minutes, and cut them into 2-3 mm slices after peeling the root bark, finally dry them in a oven under 55 degrees C, which was similar to the traditional processing method used in Bozhou. And the peeling, boiling and drying methods would affect the contents of albiflorin, paeoniflorin, benzoylpaeoniflorin and paeonol on several levels.
