Phospholipase D(PLD) is ubiquitous in bacteria,fungi,and mammal.In pathogenic microorganisms,PLD can be pathogenic determinant and play a role in spore generation.In mammalian cells,PLD functions in several signal transduction pathways,such as membrane transportation,mitosis regulation,and actin cytoskeleton regulation.In the process of pathogens invasion host cells,both of the pathogen and host cells’ PLD will be activated and a series of cascade reaction will be generated.During this process,pathogen’s PLD can regulate the polymerization and reorganization of its own actin filaments and induce the polymerization or reorganization of the host cell actin filaments near the foci,thus to promote the phagocytosis of the pathogen by host cell.Investigating the role of PLD activation in the infection will be significance for further understanding the molecular mechanism of pathogen-host cell interaction.

Aim Using chronic pre-pregnancy stress to establish a postpartum depression animal model, given a single YG,and acute ketamine was served as control, to explore the pathology of PPD and the anti-depressive mechanism of the YG on the PPD model on AKT/mTOR signaling pathway. Methods Thirty-two fe-male Balb / c were randomly assigned to two groups, the control group ( Control, Con) and the pre-pregnancy stressed group(Model,Mod) , which was subjected to 3 weeks chronic restraint stress. After the last stressor, the pre-pregnancy stressed group was housed with a male. After about 4 weeks later, the mice gave birth to pups. Then at 3 weeks postpartum, we tested the ma-ternal tail suspension test ( TST). Both YG and Ket-amine was single administered 24 hours before behavior test, with single saline for control group and PPD mod-el group. After TST,the mouse hippocampus were ex-tracted to detect the expression of AKT and mTOR. Results After 3 weeks postpartum, the model mice showed depression-like behaviors. Immobility in TST was significantly increased in vehicle groups(P <0. 01). Acute YG improved performance in the TST (P< 0. 01), which was similar to ketamine. And the PPD model mice group showed decreased phosphorylation of AKT and mTOR (P < 0. 01,P < 0. 01), compared to control group. A single dose of YG or ketamine normal-ized AKT/ mTOR signaling in the PPD model mice(P< 0. 01,P < 0. 01),( P < 0. 01,P < 0. 01). Conclu-sions Chronic pre-pregnancy stress can induce dams into postpartum depression and its mechanism maybe associated with down-regulating AKT/ mTOR signa-ling. Acute YG exerts fast antidepressant effect on this PPD model similar to ketamine, and its mechanism may be related to up-regulating AKT/ mTOR signaling in the hippocampus.

Solid dispersions technique was used to solidify buagafuran and improve buagafuran in vitro dissolution and stability. Buagafuran solid dispersions were prepared separately using PVPK30, PEG6000 and Poloxamer188 at various weight ratios as carriers. The status of buagafuran in solid dispersions was determined by using DSC and IR. The solubility, content and in vitro dissolution of pure drug and the solid dispersions were detected by using HPLC. When buagafuran/carrier was 1:5 or less, the drug existed in a solid dispersion form. Three kinds of carriers all can improve buagafuran dispersibility and in vitro dissolution. Accelerating experiment showed that buagafuran/PVPK30 < or = 1:10 solid dispersions was ageing-resistant, and the aspect, content and in vitro dissolution did not change after storaged over 3 months, but PEG6000, Poloxamer188 and a lower ratio PVPK30 solid dispersions became aged. Buagafuran/PVPK30 < or = 1:10 solid dispersions can be developed as buagafuran oral drug delivery carrier.

OBJECTIVETo assess the antihypertensive effect and safety on medicine named 'Beijing Hypertensive No. 0' in a three-year treatment of primary hypertension.
METHODSA community-based intervention study was conducted. The antihypertensive effects and adverse events were observed.
RESULTS4000 patients with primary hypertension were randomly divided into two groups with 1529 patients treated with 'Beijing Hypertensive No. 0' and 976 patients treated with other antihypertensive drugs, among which 946 and 853 patients in the two groups completed the three-year study. After treatment, the systolic blood pressure decreased 13 mm Hg and 7 mm Hg while diastolic blood pressure decreased 8 mm Hg and 4 mm Hg in the 'No. 0' group and controlled group respectively. After three years of treatment, 90.0% and 79.5% in the 'No.0' group and in the control group had reached the BP 'fulfillment criteria', which were much higher than the baseline data. Side effects occurred in 33/1274 (2.6%) cases during three years' treatment with most commonly seen as dizziness, headache, palpitation and weakness. No serious adverse reactions occurred. There were some positive effects after treated by 'No. 0', including 0.13 mmol/L decrease of TC, 0.70 mmol/L decrease of LDL-C and an average 0.12 mmol/L increase of HDL-C. All of these changes were statistically significant. There were also opposite effects as 0.13 mmol/L increase of TG, 0.24 mmol/L increase of K+, and 0.88 mmol/L increase of Na+ on average, which were also statistically significant.
CONCLUSIONCompared with the conventional treatment, this treatment of 'Beijing Hypertensive No.0' was more convenient, safe and effective in treating mild to moderate primary hypertension in the community.
