Objective To investigate the expressions of c-Fos,5-HT and spontaneous activities in single prolonged stress (SPS) stress rats,and to study the possible mechanism of posttraumatic stress disorder(PTSD).Methods forty-eight male SD rats were randomly divided into 6 groups:Individual living + SPS group (IS group),Individual living+control group (IC group),Enriched environment+SPS group (ES group),Enriched environment+control group (EC group),control+SPS group(CS group),control group(C group),8 rats in each group,spontaneous activities were measured before the experiment and post experiment at week 1,2.And the expressions of c-Fos,5-HT in the hippocampus were examined by immunohistochemical staining.Results (1) Spontaneous activity:there were no differences of crossing number and distance among 6 groups before experiment (P＞0.05).On SPS 14 days the crossing number and distance of IS group (12.12±9.64,(2.71 ± 1.99)m) decreased compared with the CS group(45.25±8.37,(6.37± 1.18) m,P＜0.05),and ES group (69.75± 10.05,(10.69± 1.50) m)showed significant increase compared with CS group (P＜0.05).(2)5-HT:the expression of 5-HT in the hippocampus of IS group(0.1125±0.0095) was significantly higher than that in CS group(0.6138±0.0059,P＜0.05),menwhile lower in ES group(0.0495±0.0074,P＜0.05).(3)c-Fos:compared with CS group(0.3108±0.0074),the expression of c-Fos in the hippocampus of IS group(0.3585±0.0150,P＜0.05) significantly increased,but decreased in ES group (0.2613±0.0063,P＜ 0.05).Conclusion Enriched environmental can improve the level of activities in PTSD rats,and to reduce the the expression of c-Fos and 5-HT in the hippocampal neurons.

Objective To explore the application of comprehensive nursing in the placement and maintenance of PICC catheter.Methods 185 patients with PICC catheter were chosen and by the use of random number table, patients were divided into observation group (93 cases) and control group (92 cases).The control group accepted routine nursing, and the observation group accepted the comprehensive nursing.The complication rate, treatment compliance and the patients ’ satisfaction were compared between groups.Results In the observation group, one case had venous thrombosis, with the incidence of 1.08%;in the control group, 6 cases had phlebitis, 4 cases had venous thrombosis, 3 cases had associated infections, 5 cases had catheter blockage, 3 cases had catheter breakage, with the incidence of 22.82%.The incidence of complications between two groups was statistically significant (χ2 =9.375,P<0.05).Compliance rate and satisfaction were 98.92%and 97.85%in observation group, which were significantly higher than 82.61% and 73.91% in the control group (χ2 =4.182,5.846, respectively; P <0.05).Conclusions The comprehensive nursing can improve the compliance rates and reduce the incidence of complications of patients with PICC catheter, and promote patients’ recovery and satisfaction.

In recent years, the contradiction between the construction of backward first aid system and the demand for emergency services in rural areas in China is increasingly serious. In order to further improve the quality and efficiency of first aid, the state has vigorously promoted the construction of the " Five Centers" , namely chest pain centers, stroke centers, trauma centers, critical maternal treatment centers, and critically ill children and neonatal treatment centers in rural areas, in an effort to develop an efficient rural emergency service network. The authors collected relevant policy documents and summarized practices of the " Five Centers" construction. On such basis, they referred to experiences of overseas emergency systems and medical rescue centers, and made focused analysis for on the functionality and mechanism of the " Five Centers" in building an innovative first-aid system, in terms of internal and external environment, institutional function positioning, resource integration, and operation mechanism. In view of the integration among " Five Centers" , pre-hospital emergency and in-hospital first aid in rural areas, information construction, personnel first aid capacity building and interest allocation, policy recommendations are proposed.
