Objective: To explore the in vitro inhibition effect of Zuojin pills on 6 cytochrome P450 isoenzymes ( CYP1A2, CYP2C8, CYP2C9, CYP2C19, CYP2D6 and CYP3A4) in human liver microsomes. Methods:The water extract of Zuojin pills, Cop-tidis Rhizoma and Euodiae Fructus was respectively incubated with human liver microsomes in the presence of seven probe substrates of CYP450 isoenzymes, and seven metabolites of cytochrome P450 probe substrate ( paracetamol/CYP1A2, 6α-hydroxypaclitaxel/CYP2C8, 4-hydroxydiclofenac/CYP2C9, 4-hydroxymephenytoin/CYP2C19, dextrorphan/CYP2D6, 6β-hydroxytestosterone/CYP3A4 and 1-hydroxymidazolam/CYP3A4) were simultaneously measured by LC-MS/MS, and the inhibitory effects were evaluated with IC50 value. Results:The IC50 value of Zuojin pills on CYP2D6, CYP1A2 and CYP3A4_T was 11. 6, 77. 4 and 97. 0 μg·ml-1 , respec-tively. The other IC50 values were from 334 to 690μg·ml-1 on CYP2C8, CYP2C9, CYP2C19 and CYP3A4_M isoenzymes. The IC50 value of Coptidis Rhizoma on CYP2D6, CYP1A2 and CYP3A4_T was 5. 8, 36. 8 and 59. 2 μg·ml-1 , respectively. The other IC50 values were from 163 to 476 μg·ml-1 on CYP2C8, CYP2C9, CYP2C19 and CYP3A4_M isoenzymes. The IC50 value of Euodiae Fructus on CYPs was over 107 μg·ml-1 . Conclusion:Zuojin pills shows notable inhibitory effect on CYP2D6, and weak inhibitory effects on CYP1A2 and CYP3A4_T. Coptidis Rhizoma has similar effects on CYPs and may be the main herbal medicine in the formu-la. Therefore, much attention should be paid to the combination of Zuojin pills and the drugs metabolized by human CYP2D6 in clin-ics.

[ ABSTRACT] AIM:To investigate the effect of maxadilan, which specifically activates pituitary adenylate cycla-se-activating polypeptide type I receptor (PAC1 receptor), on the proliferation, apoptosis and differentiation potential of human adipose-derived stem cells ( ASCs) .METHODS:ASCs from human adipose tissue were isolated by enzymatic di-gestion and cultured.ASCs were confirmed by the analysis of the markers for cell phenotypes by flow cytometry ( FCM) and adipogenic/osteogenic induction.The effect of maxadilan on ASCs viability was analyzed by CCK-8 assay and FCM.ASCs were irradiated by ultraviolet C ( UVC) at 254 nm and the absorbance of apoptotic ASCs induced by various doses of UVC was measured by CCK-8 assay.ASCs were exposed to 702 J/m2 UVC for 24 h to induce apoptosis.The effect of maxadilan on ASC apoptosis was analyzed by FCM and the determination of caspase 3 and caspase 9 levels.RESULTS:Adipose-de-rived stem cells were confirmed by the detection of the positive expression of cell phenotypes including CD29, CD44, CD59 and CD105 by FCM.The data of CCK-8 assay revealed that ASCs treated with maxadilan (80 nmol/L) had the strongest ability of proliferation.The data of FCM also demonstrated that the addition of 80 nmol/L maxadilan to ASCs in experimen-tal group markedly improved the proliferation capacity of the cells compared with control group (P<0.05).The apoptosis of ASCs exposed to 702 J/m2UVC was dramatically inhibited by the treatment with maxadilan (80 nmol/L).Such process involved the caspase signaling pathway including caspase 3 and caspase 9.There was statistical significance (P<0.05) between experiment group ( ASCs irradiated by UVC and supplemented with maxadilan) and control group ( ASCs only irra-diated by UVC) .Meanwhile, adipogenic and osteogenic differentiation potentials were both positive in experiment group and control group.CONCLUSION:Maxadilan promotes proliferation and inhibits apoptosis of the ASCs.The differentia-tion potential of ASCs toward adipogenic and osteogenic lineages wouldn’ t be altered by maxadilan.Maxadilan would bene-fit to growth and expansion of ASCs in vitro.

This study was aimed to observe the antipyresis and cholagogue effect of theFructus Gardeniae-Fructus Forsythiaeherb couple in order to explore the possible pharmacodynamic mechanism. Dry yeast suspension was subcutaneously injected into the back of rat to establish the fever model. The freeze-dried powders ofF. Gardeniae,F. Forsythiae, andF. Gardeniae-F. Forsythiaeherb couple were prepared. They were dissolved in the water for intragastric administration. SD rats were randomly divided into the normal group, model group, positive control group and Chinese medicine group. The Chinese medicine group was subdivided into the group ofF. Gardeniae,F. Forsythiae, andF. Gardeniae-F. Forsythiaeherb couple. The concentration of herbal water extract was 10 mL·kg-1 (which equaled to 3 g·kg-1 of a single crude herb). The concentration of positive control was 10 mL·kg-1. Intragastric administration of equal amount of normal saline was given to the blank group and the model group. Except rats in the normal group, rats in other groups were subcutaneously injected with 10 mL·kg-1 of 15% dry yeast suspension on the back of to establish the fever model. Electronic thermometer was used to record the body temperature of rats at 0, 1, 4, 5, 6, 7 and 8 h after the injection, respectively. Meanwhile, bile was collected from 1-1, 1-2, 2-4, 4-6, 6-8, 8-12, 12-24 h, respectively. Observation was given on changes of body temperature and bile amount of rat. The results showed thatF. Gardeniae,F. Forsythiae, andF. Gardeniae- F. Forsythiaeherb couple had certain effect to reduce the body temperature of rats. The temperature-reducing effect of the combination of both herbs was better than a single herb. TheF. Gardeniae -F. Forsythiae herb couple can reduce the body temperature of fever rat (P < 0.05, orP < 0.01). It had a little effect on the body temperature of normal rat. TheF. Gardeniae - F. Forsythiaeherb couple can promote the bile secretion, which was better than the single using of F. Gardeniae (P < 0.05). It was concluded that theF. Gardeniae - F. Forsythiaeherb couple had better temperature-reducing effect than the using of a single herb; however, there was no significant difference. But it had obvious effect on the promotion of bile secretion, which indicated the strengthening of cholagogue effect.

BACKGROUND:With the deepen understanding on the biological function of Rho/ROCK pathway, new ROCK inhibitors continue to be discovered, and ROCK inhibitors show good promoting effects on the survival, proliferation and migration of keratocytes. Research on ROCK inhibitors wil provide more donor materials or seed cels for regenerative medicine and clinical cel transplantation. OBJECTIVE:To summarize and explore the progress in the treatment and application of corneal disease using the ROCK inhibitors Y-27632 and Y-39983. METHODS:The PubMed database and CNKI database were retrieved by computer to search the relevant literature published between 2008 to 2015 using the key words of “corneal endothelial cel, corneal epithelial cel, ROCK inhibitor, Y-39983, Y-27632” in English and Chinese, respectively. Relevant articles in line with the theme were screened and analyzed. RESULTS AND CONCLUSION:Totaly 264 papers were initialy searched. At last, 45 papers were selected. Currently there are two main ROCK inhibitors: Y-27632 and Y-39983, but both of which are stil in basic research stage and clinical testing stage. Y-27632 promotes the proliferation and activity of corneal epithelial stem cel after resuscitation; Y-39983 as a novel ROCK inhibitor can be better to inhibit Rho kinases activity than Y-27632, thereby more effectively promoting the healing of the corneal endothelium. There are many studies on the application of ROCK inhibitors in corneal treatment, but not a stable method established to obtain seed cels. Each method has its own advantages and disadvantages, and how to overcome these disadvantages and to find fast and stable access to seed cels is the future direction of development.
