AIM: To investigate effect of naringenin on ADP-induced platelet aggregation and its possible mechanism.METHODS: The levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) were measured in the platelets with ADP stimulation using ELISA in the presence or absence of different concentrations of naringenin.The effect of naringenin at different concentrations on the change of phosphodiesterase (PDE) activity was measured by high efficiency liquid chromatography.The effects of naringenin at different concentrations on phosphorylation of vasodilator-stimulated phosphoprotein (VASP) at positions Ser157 and Ser239 in washed platelets with ADP stimulation were analyzed by Western blot.The phosphorylation of VASP at Ser239 was also analyzed in the presence of protein kinase A (PKA), protein kinase G (PKG), or protein kinase C (PKC) inhibitors before incubation with naringenin.The platelet aggregation was measured in the presence of PKA or PKG inhibitors before incubation with naringenin.RESULTS: Naringenin elevated cGMP levels significantly but not cAMP levels in the platelets with ADP stimulation in a dose-dependent manner.Naringenin inhibited PDE activity.Naringenin increased the phosphorylation of VASP at Ser239 in a dose-dependent manner in the platelets with ADP stimulation but only modest changes in the phosphorylation at position Ser157.The phosphorylation level of VASP at Ser239 position was inhibited when the platelets were treated with PKA inhibitor before incubation with naringenin.Incubation of platelets with neither PKG nor PKC inhibitors before treatment with naringenin affect the phosphorylation of VASP at Ser239.Pretreatment with PKA inhibitor but not PKG inhibitor significantly reversed the antiplatelet aggregation by naringenin in ADP-stimulated platelets.CONCLUSION: Naringenin may inhibit platelet activation through the elevation of cGMP-and PKA-mediated VASP phosphorylation.

Objective To explore the effects of case management on the stigma and coping style of discharged patients with bipolar disorder.Methods During October 2012 to October 2015, 116 cases of patients with bipolar disorder in our hospital were selected as the research object. Patients were randomly di-vided into the control group and the observation group, with 58 cases in each group. Patients in two groups were given routine nursing care, and patients in the observation group also received case management. The scores of stigma, coping style and quality of life (QOL) of patients between two groups before and after intervention were compared.Results After intervention, the scores of social contact, ability and treatment of stigma scale in the observation group were (12.75±3.05), (9.53±2.28) and (11.13±2.45), and they were all significantly lower than the control group (t=2.396,2.504,2.559;P<0.05). After intervention, the scores of solving problems, self-accusation, seeking help, fantasy, avoidance and rationalization of coping style scale in the observation were (8.02±3.06), (3.11±2.16), (6.13±2.62), (3.05±2.24), (4.09±2.06) and (6.61±3.28), and they were significantly better than those in the control group (t=2.573,2.537,2.186,2.389,1.996,2.557;P<0.05). After intervention, the total QOL health score of patients in the observation (56.87±17.13) was significantly better than (53.83±16.46) in the control group (t=2.279,P<0.05).Conclusions The case management can significantly reduce the stigma of patients with bipolar disorder, and improve the coping style and QOL of patients, so it can be further promoted and used.
