Objective To observe the effects of Baishile Capsules on neonatal neuronal activity and synaptic plasticity in hippocampus of depression model rats;To explore its mechanism of antidepressant.Methods Totally 32 SD rats were randomly divided into blank group,model group,fluoxetine group(5.4 mg/kg)and Baishile Capsules group(2.88 g/kg),with 8 rats in each group.The depression rat model was established by chronic unpredictable mild stress and single cage feeding,and drugs were administered at the same time as modeling for 21 consecutive days.Forced swimming test and open field test were used to evaluate the depressive-like behavior of rats,Golgi staining was used to observe the synaptic morphology of hippocampal neurons,and immunofluorescence was used to detect the positive expressions of BrdU/GABA-B,BrdU/c-fos,BrdU/GAP-43,BrdU/MAP-2 and CXCR4 in hippocampal tissue.Results Compared with the blank group,the immobility time of forced swimming experiment in the model group increased,and the horizontal and vertical time of open field experiment decreased significantly(P<0.01);the hippocampal neurons dendrites and dendritic spines atrophied,the density decreased,the branches became shorter,synaptic structure becomes blurred,and the longest and total lengths of synaptic branches significantly decreased(P<0.01);the positive expressions of GABA-B,c-fos,GAP-43 and MAP-2 proteins in hippocampal neonatal neurons decreased(P<0.05,P<0.01),and the expression of CXCR4 in hippocampal tissue decreased significantly(P<0.01).Compared with the model group,the immobility time of the forced swimming experiment in fluoxetine group and Baishile Capsules group significantly reduced,and the horizontal and vertical activity time of the open field experiment significantly increased(P<0.01);the number of dendritic spines in hippocampal neurons increased,synaptic damage improved,and the length of the longest and total branches of synapses significantly increased(P<0.01);the positive expressions of GABA-B,c-fos,GAP-43 and MAP-2 in hippocampal neonatal neurons significantly increased(P<0.05,P<0.01),and the positive expression of CXCR4 in hippocampal tissue significantly increased(P<0.01).Conclusion Baishile Capsules can regulate hippocampal synaptic plasticity and nerve regeneration by improving the activity and function of hippocampal neonatal neurons in depression model rats,exerting antidepressant effects.

Objective To investigate the effecs of evidence-based nursing of the treatment with propranolol forthe intractable infantile hemangiomahemangioma. Methods Dividing the children who were treated with propranolol into experimental groups and matched groups randomly according to the random number table each 42 .The experimental group adopted evidence-based care,according to PICO tool description of the problem and combining the results of theresponsibility nurse′s regular follow-up and assessment to come up with evidence-based problems,seeking for high-level evidences,combining the existing conditions of careand having formulated corresponding care norms,contingency plans for adverse reactions,healthy education card,the operation videos and other measures and they are implemented.The control group adopted the routine care procedure.two groups of effects were determined by the Achauer level 4 classification after 12 months of treatment,and evaluating the condition of occur of blood pressure drop ,slow heart beat ,diarrhea, sleepdisorders, hypoglycemia and other adverse reactions in both groups during the process of treatment. Results there was statistical significance in the difference of two groups′Achauer 4 levels. The numbers of Ⅰ, Ⅱ, Ⅲ, and Ⅳ in the two groups were 3, 7, 20, 12, and 11, 15, 11, 5, respectively (t1=1372, t2=2132, P<0.05). The two groups had a statistically significant difference in blood pressure, heart rate, diarrhea, sleep disorder, and low blood sugar response. The numbers of two groups were 12, 2, 3, 6, 1 and 26, 15, 12, 21, 8 respectively (χ2=6.098-12.464, all P<0.05). Conclusions Evidence-based nursing enhances the treatment effectiveness of theintractable infantile hemangioma with propranolol effectively and has preventing the occur of adverse reactions during the process of treatment.

Objective To explore the effects of application of the new model of evidence-based land humanized nursing in patients with universal pustular psoriasis.Methods Divided 84 patients with universal pustular psoriasis into the experimental group (42 cases) and the control group (42 cases) randomly.Evidence-based questions were raised according to the requests about humanized nursing of patients in the experimental group,and then retrieved and screened literature,sought high-level evidence,combined with previous nursing experience,developed new evidence-based and humanized nursing programs and implemented in the experimental group.The control group used conventional care program.Two weeks after admission,pain,anxiety,depression degree and the complications of two groups were compared.Results Two weeks after admission,the patients with 0 to 5 levels of pain in the experimental group was 0,5,26,7,4 and 0 cases respectively,which in the control group was0,0,0,12,20 and 10 cases respectively,the difference was significant between the two groups (U=6.957,P＜0.01).Anxiety and depression scores in the experimental group was (41.35±4.30) and (42.55±7.71) respectively,which in the control group was (51.31±4.56) and(50.36±6.89) respectively,the difference were significant between the two groups (t=10.540 and 4.893,P＜0.01).Conclusions The new model of evidence-based and humanized nursing can effectively improve the effects of humanized nursing in patients with universal pustular psoriasis.
