Objective To explore the effects of beraprost sodium (BPS) on angiotensin Ⅱ(AngⅡ)-induced podocyte apoptosis and the relationship between BPS and peroxisome proliferator activated receptor δ(PPARδ). Methods Differentiated mouse podocytes were exposed to AngⅡ, further treated with BPS (or GSK0660) for 24 h. Podocyte apoptosis was detected by flow cytometry and AnnexinV-FITC staining. Bax , Bcl-2 and PPARδ mRNA were assessed by RT-PCR. Results AngⅡ promoted podocyte apoptosis and Bax mRNA expression significantly, down-regulated Bcl-2 and inhibited PPARδ mRNA (P < 0.05). Conversely, treatment with BPS reduced AngⅡ-induced podocyte apoptosis and Bax mRNA expression and promoted Bcl-s expression significantly resulting in an increase of PPARδ mRNA expression (P < 0.05). With the inhibition of PPARδ, podocyte apoptosis and Bax mRNA expression increased while Bcl-2 mRNA expression reduced. Conclusion BPS can effectively reduce AngⅡ-induced podocyte apoptosis , which is associated with the activation of PPARδand regulation of Bcl-2/Bax mRNA expression.

Objective To examine the effects of IL-10 on cardiac fibroblasts ( CFBs) proliferation and phenotype transformation to myofibroblasts (MyoFbs) induced by transforming growth factor-β1 (TGF-β1);and to investigate the regulating pathways .Methods Cardiac fibroblasts were isolated from cardiac ventricles of neonatal SD rats . The passage 2~4 were used and divided into the following groups for treatment:1) control group, 2) IL-10 reac-tion group, 3) TGF-β1 reaction group, and 4) IL-10 plus TGF-β1 reaction group (TGF-β1 treatment followed with IL-10 pretreatment ) .Cells proliferation was assessed by MTT assay and immunocytochemistry staining for prolifera-ting cell nuclear antigen (PCNA);the phenotype transformation into MyoFbs was assessed by immunocytochemistry of α-smooth muscle actin (α-SMA);extracellular signal related kinase ( ERK1/2) and P38 kinase pathways were assessed by western-blot.Results TGF-β1 (10 μg/L) treatment boosted the proliferation and the expression ofα-SMA significantly (P<0.01), while IL-10 (10, 50 or 100 μg/L) plus TGF-β1 co-treatment induced lower cell proliferation and expression of α-SMA than treating with TGF-β1 alone ( P<0.05 ) , with the inhibitory effect of IL-10 being concentration dependent .TGF-β1 could significantly stimulate the ERK 1/2 and P38 kinase phospho-rylation ( P<0.01 ) , however IL-10 (100 μg/L) plus TGF-β1 co-treatment failed to down-regulated the phospho-rylation of ERK1/2 and P38 kinase compared with TGF-β1 alone ( ERK1/2:P<0.05;P38:P<0.01 ) .Conclu-sions IL-10 can attenuate TGF-β1-induced CFBs proliferation and phenotype transformation to MyoFbs .The in-hibitory effects may explained by a mechanism of inhibiting the activation of ERK 1/2 and P38 kinase .

Objective To investigate the status of self-care ability and cognition among disabled elderly,and to analyze the relationship between self-care ability and cognition,then analyze their influencing factors.Methods A total of 813 disabled elderly accepted long-term care at community or facility were recruited by stratified sampling method and investigated by socio-demographic questionnaire,activities of daily living and short portable mental status questionnaire.Results The total scores of self-care ability of the long-term care disabled was 32.01±11.59,and the total points of cognition was 3.77±3.24.Disabled elderly with severe disorders of self-care ability had a higher obstacle rate in every cognition ability than those with mild disabilities (P＜0.001).There were differences in orientation and memory function with different persistent disabled time (x2 =11.875,14.758,P＜0.01).Disabled elderly with cognition obstacles have a higher obstacle rate in every self-care aspect than those with normal cognition (P＜0.01).The multiple regression analysis showed that the educational level (β=-0.067),arital status (β=-0.071),disabled persistence time (β=0.121),orientation ability (β=0.403),the amount of cognition obstacles (β=0.443) were the influence factors of Basic Activities of Daily Living(BADL) among disabled elderly ; and disabled persistence time (β=0.116),orientation ability (β=0.417),recalled ability (β=0.275),memorial ability (β=0.189),calculative ability (β=0.257),the amount of cognition obstacles (β=0.358) were the important factors influence Instrumental Activities of Daily Living(IADL).Conclusion The self-care ability and cognition of the long-term care elderly were declining sharply,and influencing each other.It is advisable to offer them direct long-term care service combined with the laws and characteristics of cognition and self-care ability.

Objective To compare the clinical effect of different doses of methylprednisolone in the treatment of children with severe hand foot mouth disease research and analysis. Methods 100 patients in our hospital from January 2014 to August 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The control group were treated with small doses of methylprednisolone, 2 mg/ (kg?d), intravenous injection. The experimental group was treated with large dose of methylprednisolone, 10～15 mg/(kg?d) intravenous infusion. The therapeutic effects of the experimental group and the control group were compared and analyzed. Results after the corresponding treatment, the number of adverse reactions in the experimental group was 31, the adverse reaction rate was 62.0％, and the adverse reaction rate in the control group was 60.0％. There was no significant difference in the incidence of adverse reactions between the two groups. The upper respiratory rate and critical illness in the experimental group were 26.0％ and 32.0％, significantly lower than that of the control group (P<0.05). The average remission time of the patients in the experimental group was (2.19±1.01) days. The symptomatic remission time in the control group was (4.19±1.89) days. The remission time of the control group was significantly longer than that of the experimental group, with statistical difference (P<0.05). Conclusion The short term large dose of methylprednisolone in treatment of children with severe HFMD clinical effect is ideal, can be reduced to critical illness rate, less symptom remission time, with the further promotion of the clinical significance.

AlM: To research the characteristics of positive relative accommodation ( PRA) , negative relative accommodation (NRA) and PRA/NRA ratio in myopes. To analyze the relationship among PRA, NRA, PRA/NRA ratio, spherical equivalent degree, years and habbits of wearing glasses, myopia development, and pupil diameter.METHODS: Aretrospective study of ninety eyes in the 180 th Hospital of Quanzhou from August 2014 to December 2014. PRA, NRA and PRA/NRA ratio were compared among low, moderate, high myopes and emmetropes. The correlation were analyzed among PRA, NRA, PRA/NRA ratio, spherical equivalent degree, years and habbits of wearing glasses, myopia development and pupil diameter. PRA, NRA, PRA/NRA ratio, years and habbits of wearing glasses and pupil diameter were compared between progress group and non-progress group.RESULTS: ( 1 ) Without statistical differences in age, sex and intraocular pressure, PRA and PRA/NRA ratio of myopes were lower than emmetropes, while NRA was higher. (2) Without statistical differences in age, sex and intraocular pressure, PRA, PRA/NRA ratio and NRA had no statistical differences while years and habbits of wearing glasses had statistical differences among low, moderate, high myopes. ( 3 ) With longer years of wearing glasses, PRA, PRA/NRA ratio were larger and NRA, pupils were smaller. ( 4 ) Without statistical differences in age, diopter and intraocular pressure, one group which were not easy to deepen degree had more often-wear-glasses myopia patiens and longer years of wearing glasses, the other group which were easy to deepen degree had more seldom-wear-glasses myopia patiens and shorter years of wearing glasses.CONCLUSlON: PRA and PRA/NRA ratio of myopes were lower than emmetropes, while NRA was higher. No correlated relation was detected among PRA, NRA, PRA/NRA ratio, spherical equivalent degree and myopia development. lt suggests the onset and progress of myopia are related to many factors. Wearing-glass timely and accurately can release the decline of PRA and PRA/NRA ratio and slow down degree development in myopes.
