OBJECTIVETo compare the efficacy differences between fire needling therapy and oxycycline tablets for the treatment of moderate to severe acne vulgaris.

METHODSSixty cases of moderate to severe acne vulgaris were randomly divided into a fire needling group and a medication group, 30 cases in each one. The pricking method of fire needling at Ashi points around damaged skin was applied in the fire needling group, once every five days for totally 4 times. The oral administration of oxycycline tablets, 100 mg, was applied in the medication group, twice daily for 20 days, also external application of adapalene gel before sleep was adopted. The fading time of skin damage, including papule, pustule, nodule and cyst in the two groups was recorded and clinical efficacy was compared. After the treatment, two-month follow-up was performed to observe the recurrence rate in the two groups.

RESULTSThe curative rate was 69.0% (20/29) in the fire needling group, which was statistically different from 40.0% (12/30) in the medication group (P < 0.05). The fading time of each type of skin damage in the fire needling group was shorter than that in the medication group [papule: (2.67 +/- 0.66) d vs (4.36 +/- 0.61) d; pustule: (2.47 +/- 0.57) d vs (4.27 +/- 0.55) d; nodule: (7.76 +/- 1.06) d vs (9.88-1.30) d; cyst: (11.81 +/- 1.54) d vs (14.79 +/- 0.89) d, all P < 0.05]. The recurrence rate was 46.4% (13/28) in the fire needling group, which was not significantly different from 44.0% (11/24) in the medication group (P > 0.05).

CONCLUSIONThe acne vulgaris could be fast and effectively treated by fire needling therapy, which has shorter fading time than oxycycline tablets. However, the preventive effect is not different between the two theraies.

OBJECTIVE To investigates the effects of imperatorin on the oxidative stress in the cerebral cortex and hippocampus after focal cerebral ischemia/reperfusion injury. METHODS Transient focal cerebral ischemia/reperfusion model in male Sprague-Dawley rats was induced by 2 h middle cerebral artery occlusion followed by 24 h reperfusion. Imperatorin (1.25 and 2.5 mg·kg- 1) or vehicle were administered intraperitoneally at 1, 5 and 9 h after the onset of ischemia. At 24 h after reperfusion, the biomarkers of oxidative stress such as the levels of reactive oxygen species (ROS), lipid peroxidation products malondialdehyde (MDA), nitric oxide (NO) and total antioxidant capacity (T-AOC), the activities of inducible nitric oxide synthase (iNOS), superoxide dismutase (SOD) and catalase (CAT) in the cerebral cortex and hippocampus were observed. We also assessed the nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and the NAD(P)H-quinone oxidoreductase 1 (NQO-1) protein expression by Western blot. RESULTS As compared to vehicle-treated animals, imperatorin treatment significantly reduced the ROS, MDA, NO levels and iNOS activity, increased T-AOC and the activities of SOD and CAT. Furthermore, imperatorin treatment also significantly induced the nuclear translocation of Nrf2, enhanced the protein expression of HO-1 and NQO-1 in the cerebral cortex and hippocampus. CONCLUSION Our findings indicate that imperatorin can protect the brain against the excessive oxidative stress induced by cerebral ischemia/reperfusion through activation of Nrf2 signaling pathway.

For screening the potential drugs as anti-liver fibrosis candidates, we established a high- throughput drug screening cell model based on COL1A1 promoter. The activity of COL1A1 promoter and luciferase reporter gene can be elevated by TGF-β1, and inhibited by candidate drugs. We constructed a recombined plasmid with COL1A1 promoter and luciferase reporter gene pGL4.17, the activity of COL1A1 promoter was reflected by fluorescence intensity. COL1A1 promoter activity was detected by Dual-Luciferase Reporter Assay System, it came that the relative luciferase activity of COL1A1 promoter was 15.98 times higher than that of control group induced by TGF-β1, showing the recombined plasmid could be used in cell model. The recombined plasmid was transfected into human hepatic stellate cells LX2, detected the effect of potential drugs, and obtained a stable expression system through stable transfection and monoclonal cell culture. A sample which could reduce COL1A1 promoter activity signally by our cell model, decreased collagen I mRNA and protein expression detected by real-time RT-PCR and Western blotting. It indicates this novel cell model can be used in high-throughput drug screening of potential anti-liver fibrosis drugs.

To establish an HPLC-MS/MS method for the analysis of quercetin, kaempferid and isorhamnetin in rats plasma and study its pharmamacokinetics after an intragastrical administration of Hippophae rhamnoides extracts. Five healthy male Sprague-Dawley (SD) rats were given single doses of H. rhamnoides extracts (quercetin 26.35 mg x kg(-1), kaempferid 4.040 mg x kg(-1), isorhamnetin 31.37 mg x kg(-1)), and then their orbital sinus blood samples were collected at different time points. The drug plasma concentration of the three flavonoids was determined by HPLC-MS/MS method. After that, the main pharmacokinetics parameters were calculated by using Kinetica 5. 0. 11 software. The methodological test showed that the linear concentration ranges of quercetin, kaempferid and isorhamnetin were 7.500-600.0 μg x L(-1) (R2 = 0.998 5), 1.000-80.00 μg x L(-1) (R2 = 0.998 5 ) and 10.00-800.0 μg x L(-1) (R2 = 0.998 0), respectively. The inner and inter-days precisions were both less than 14.0%. The plasma samples showed a good stability and consistency with the requirement of biological sample analysis after the samples were frozen once and placed at - 20 degrees C for 15 d and room temperature for 6 h and the treated analytes were placed at -20 degrees C for 24 h. For quercetin, the pharmacokinetic parameter t(½β), AUC(0-∞), MRT(0.∞), C.(max) and T(max) were (113.3 ± 19.37) min, (12 542.14 ± 3 504.05) μg x h x L(-1), (119.6 ± 13.29) h, (164.6 ± 27.33) μg x L(-1) and (5.199 ± 0.840 3) h, respectively. For kaempferid, the pharmacokinetic parameters t(½β), AUC(0-t), MRT(0-∞), C(max) and T(max) were (79.85 ± 17.15) min, (934.51 ± 94.59) μg x h x L(-1), (81.50 ± 13.75) h, (80.15 ± 14.24) μg x L(-1) and (3.827 ± 0.902 7) h, respectively. For isorhamnetin, the pharmacokinetic parameters t1,2,, AUC(0-t), MRT(0-∞), C(max) and T(max) were (118.3 ± 20.73) min, (26 067.77 ± 4 124.60) μg x h x L(-1), (129.0 ± 16.30) h, (269.6 ± 29.32) μg x L(-1) and (6.513 ± 1.450) h, respectively. The HPLC-MS/MS analysis method established in this study was proved to be sensitive and accurate and could be applied in the pharmacokinetic study of quercetin, kaempferid and isorhamnetin in rat plasma.
