Objective To observe the inhibitory role of valproic acid (VPA) in hypertrophic cardiomycytes induced by angiotensin Ⅱ (Ang Ⅱ)in rats. Methods The cultured rat cardiomyocytes were divided randomly into control group, hypertrophic group and VPA group. They were treated with Ang Ⅱ to induce hypertrophy and then given with VPA. The morphologic changes of cardiomyocytes were observed under the contrast phase microscope and electron microscope. The mRNA levels ofβ-MHC were exmained by reverse transcriptase polymerase chain reaction (RT-PCR) method. The protein expression of C-FOS was exmanined by immunohistochemistry method. Results Stimulated by Ang Ⅱ, the cardiomyocytes were enlarged under the contrast phase microscope and the ultrastructure also changed. After stimulated by Ang Ⅱ, the mRNA level of β-MHC and the protein expression of C-FOS increased in the hypertrophic cardiocytes. Given by VPA, these data decreased accordingly. Conclusion VPA may inhibit the cardiomyocyte hypertrophy induced by angiotensin Ⅱ in some degree.

To study the influence of individualized medication guidance based on an Short Messaging Service( SMS) platform on the medication compliance in the patients with diabetes. Methods: Totally 100 cases of diabetic patients from the outpa-tient section were randomly divided into two groups using a number method with 50 ones in each, namely odd number was in the obser-vation group and even number was in the control group. The observation group was given pharmaceutical guidance based on the SMS technology platform by pharmacists, and the control group was given telephone follow-up once a week to understand the medical situa-tion. At the beginning of the study and after three-month treatment, the medication compliance in the two groups was evaluated, and the control situation of blood glucose was also compared. Results:There was no significant difference in the medication compliance be-tween the two groups at the beginning (P>0. 05). After the 3-month treatment, the blood glucose and medication compliance between the two group had statistical significance (P<0. 01). Conclusion:Based on a mobile phone short message technology platform, indi-vidualized clinical pharmaceutical guidance can significantly improve the medication compliance in diabetic patients.

This study analysed the tissue specific expression of critical genes involved in chlorogenic acid and luteolin biosynthesis, for exploiting the molecular mechanism of components biosynthesis in Lonicera confusa. Expression of PAL, 4CL, C4H, CHS, CHI, FNS and HQT gene families of chlorogenic acid and luteolin biosynthesis-related genes in buds and leaves of L. confusa were analyed by Real-time PCR. Expressions of PAL1, C4H1, 4CL1, CHS1, CHI3 and HQT2 in buds were lower than that in leaves, and expressions of PAL3, 4CL2, CHI2 and FNS2 in buds were higher than that in leaves. The results indicated that that PAL3 and 4CL2 may be associated with accumulation of chlorogenic acid, and the expression patterns of PAL1, CHS1, CHI3 and HQT2 in buds and leaves of L. confusa were different with L. japonica. This study provided some theoretical basis for the further research on genetic mechanism of active components differences in L. confusa and L. japonica.

Objective To study and compare the metabolism of Hedyotis diffusa flavonoid extract in intestinal flora from human, normal rats and pseudo germ-free rats in vitro. Methods Intestinal flora of human, normal rats and pseudo germ-free rats were incubated with Hedyotis diffusa extract, rutosid, isoquercitrin and quercitrin under anaerobic conditions at 37℃.High-performance liquid chromatography with diode-array detection ( HPLC-DAD ) was used for the analysis of components and metabolic products.The trends of metabolic transformation of the various components were analyzed according to the changes in chromatographic peak areas at different incubation time points. Results The components of Hedyotis diffusa extract and its monomer were quickly metabolized by human and normal rat intestinal flora and the main metabolite was quercetin.However, they were hardly metabolized by intestinal flora from pseudo germ-free rats. The metabolism effect of intestinal flora was weaker on components than on the corresponding monomers. Conclusion By comparing flavonoids metabolism in intestinal flora from human, normal rats and pseudo germ-free rats, the important role of intestinal microflora in the metabolism of flavonoids is further confirmed.
