The purpose of this study is to investigate the enantioselectivity of norgestrel (NG) transdermal permeation and the potential influence of linalool and lipids on the enantioselectivity. In vitro skin permeation studies of NG across the excised rat skins were performed with Valia-Chien diffusion cells, and the permeation samples were analyzed by enantioselective HPLC. The possible enantioselective permeation of NG across intact rat back skin and lipids extracted rat back skin and the influence of linalool were evaluated. The skin permeation rate of dl-NG was two times higher than that of l-NG when donor solutions (EtOH/H2O 2 : 8, v/v) containing l-NG or dl-NG. It may be mainly attributed to the solubility discrepancy between enantiomer and racemate. The enantioselective permeation of dl-NG across intact rat skin was observed when the donor solutions containing dl-linalool. The permeation flux of l-NG was 22% higher than that of d-NG. But interestingly, the enantioselective permeation of dl-NG disappeared under the same experimental condition except that the lipid extracted rat skin was used. Attenuated total reflection-fourier transform infrared spectroscopy analysis of stratum corneum showed that the wave number for asymmetric CH2 stretching vibrations of lipids treated with dl-linalool was greater than that of the control. The results indicated that the enantioselective permeation of NG may be contributed by the interaction between dl-linalool and lipids. More than half of lipids were composed of ceramides. The stereospecific interaction maybe existed among chiral enhancer (linalool), lipids (ceramides) and/or chiral drugs (NG).

Objective To analysis the human T lymphotropic virus (HTLV) infection status in Wenzhou among voluntaty blood donors.Methods Selected 72 417 voluntary blood donors of Wenzhou from from March,1,2016,to November,30,2016,to screen HTLV-Ⅰ / Ⅱ antibody by ELISA method.The positive samples were reexamined two times,two test results of samples were determined positive by ELISA.HTLV positive samples was confiemed by Western Blotting (WB).Results Screened 23 cases of anti-HTLV positive by ELISA method,then confirmed 9 cases of HTLV positive by Western Blotting (WB).HTLV infection rate of Wenzhou blood donors was 0.01％ (9/72 417).Conclusions HTLV infection was found among volunteer blood donors in Wenzhou,but the HTLV infection rate of volunteer blood donors in Wenzhou is still at a relatively low level.

This study aimed at investigating the dose-effect relationship of SFI between the blood viscosity and the early-and mid-stage cardiogenic shock and the mediatory effect on rats.The end or root of left anterior descending coronary arteries (LADCA) was ligatured to establish the rat model of the early-and mid-stage cardiogenic shock.The blood viscosity indexes included low shear rate (LSR,10/s),middle shear rate (MSR,60/s),high shear rate (HSR,150/s) of the whole blood viscosity and plasma viscosity (PV),being observed 60 mins after the venous administration of 0.10,0.33,1.00,3.30,10.00 and 20.00 mL·kg-1 SFI (low dosage range:0.1-1.0 mL·kg-1,middle dosage range:1.0-10 mL·kg-1,high dosage range:10-20 mL·kg-1) with a blood rheometer.Dose-response curves were fitted by GraphPad Prism 6.0 software,the dose-response relationship of SFI between the blood viscosity and the early-and mid-stage cardiogenic shock in rats was evaluated to calculate the dose threshold parameters of the indexes.It was found that the blood viscosity indexes were improved with the dosage of 10 mL·kg-1 SFI in rats with the early-stage cardiogenic shock,while the dose-response curves of LSR,MSR and HSR at the early stage all presented favorable s shapes.Most of the effective dose range [D]2o-[D]80 and the threshold dose [D]20 were between 3.3 and 6.3 mL· kg-1.The four indexes of blood viscosity were improved with the administration of 10 and 20 mL·kg-1 SFI in mid-stage model rats with favorable s shapes in the dose-response curves.Most of the effective dose range and the threshold dose were in the range of 3.3 to 10.0 mL·kg-1.In conclusion,most of the dose-response curves of blood viscosity indexes in early-and mid-stage cardiogenic shock rats presented favorable s shapes with the threshold dose between 3.3 and 10.0 mL·kg-1,indicating an effective middle dosage range,which was converted into clinical dosage about 37.1 to 112 mL each day.The research provided an experimental basis for clinical medication.

Background and purpose:Chemotherapy with docetaxel has become the first line treatment for hormone refractory prostate cancer.To preliminarily investigate the efficacy of docetaxel plus prednisone and mitoxantrone plus prednisone for treating metastatic hormone-refractory prostate cancer and to further evaluate its adverse events in Chinese patients. Methods:83 patients with metastatic hormone-refractory prostate cancer were candidates for the trial and given a combination of docetaxel 75 mg/m2 intravenously on d 1 or mitoxantrone 12 mg/m2 on day 1 plus prednisone 5 mg twice daily on d 1~21, 21 days a cycle. Serum PSA level, relief of bone pain, myelosuppression, and vomiting were recorded and calculated.Results:Docetaxel plus prednisone were administered to 44 patients, 13.6% (6/44) of them got a complete response; 29.5% (13/44) achieved a partial response; 29.5% (13/44) had stable disease; and 27.3% (12/44) progressed. The average time to PSA progression was 37.8 weeks (12~101 weeks) in the responsive and stable disease patients. The 12 patients with progressive disease were given MP as a salvage therapy, and 16.7% (2/12) achieved a partial response, 25.0% (3/12) had stable disease. Only 2 patients died of disease aggravation. Mitoxantrone plus prednisone were given to 39 patients, and 7.7% (3/39) of them got a complete response; 25.6% (10/39) achieved a partial response; 25.6% (10/39) had a stable disease; and 41.0% (16/39) of patients progressed. The mean time to PSA progression was 25.3 weeks (8~61 weeks) in the responsive and stable disease patients. The 14 patients with progressive disease were administered DP as a salvage therapy, and 7.1% (1/14) achieved a complete response, 35.7% (5/14) got a partial response, 21.4% (3/14) had stable disease and from the new baseline. Four patients died at the last follow-up.Conclusions:In Chinese patients, docetaxel plus prednisone is better than mitoxantrone plus prednisone in PSA response rate and PSA control, but there occurs a bit more toxicity. When the tumor is resistant to one regimen, the other might be still effective in controlling the disease from progression.
