Objective To understand the status and demand of training of community nurses, and to improve the quality of community nursing services. Methods 161 community nurses were surveyed using a stratified sampling in proportion and self-designed questionnaire. Results 23.0% of nurses in this group had never partiticipated in the training; 52.8% of nurses thought they needed the training very much; 58.4% of nurses thought the training work should be shouldered by the organization such as nursing association. 49.1% of nurses thought the main reason influencing participation in the training for the community nurses was short of funds. Conclusions The on-job training work for community nurses is not extensive and thorough. All levels of government should emphasize the on-job training work for community nurses so as to ensure the continuous development of community nursing services.

Objective To observe the influence of environment stimulation on learning and memory ability and hippocampal pathology of neonatal rats with hypoxic-ischemic brain damage (HIBD).Methods The models of HIBD SD rats were established by the method of Rice, and were divided randomly into three groups: enriched environment stimulation group (EE), impoverished environment stimulation group (IE), and standard environment stimulation group (SE). The sham-operation rats were served as control group. Different environment stimulation was administrated to the rats since day 1 after HIBD.On the day 28,Morris water maze was used to evaluate the learning and memory ability. HE staining and nissl stain were employed to observe the pathological change and the number of neurons in hippocampus of rats.Results The learning and memory ability of EE group was significantly higher than that of SE group (P0.05), and the ability of SE group was higher than that of IE group ( P0.05). The number of SE group was lower than that of Sham group (P

Objective To observe the changes in gut mucosal barrier and gut-origin bacteria-endotoxin translocation in acute necrotizing pancreatitis (ANP) rats. Methods Wistar rats were divided randomly into normal group (n=6), sham operation group (n=30) and ANP group (n=39). ANP was introduced by infusion of artificial bile into biliopancreatic duct. Morphology of pancreas and intestine were observed and tight junction on ileum epithelia were assessed by cryofracture replicas electroscopy. Plasma levels of D-lactic acid and endotoxin were examined at various time points. The rates of bacterial translocation to abdominal organs were also calculated. Results Mucosal and tight junction damages of the gut were found during early stage of ANP. Simultaneously, plasma D-lactate levels increased and endotoxemia occurred. The rate of bacterial translocation to organs was 59.5% 72h after ANP occurred. Conclusions Gut barrier function can be injured in the early stage of ANP, and resulting in gut origin bacteria-endotoxin translocation, which may be the originator of systemic inflammatory reaction and secondary infection of the pancreas.

Phosphatase and tensin homology deleted on chromosome 10 (PTEN) plays an important role in the proliferation,migration,differentiation,apoptosis and synapse establishment of nervous system.Elucidation of PTEN function is helpful to understand the mechanisms of neural development,and thus may find new therapies for diseases in central nervous system using PTEN as a target.

Objective To explore the effects of Atorvastatin and Simvastatin on serum levels of lipid,high sensitive C-reactive protein (hs CRP)and ventricular remodeling in patients with acute coronary syndromes(ACS).Methods In this prospective study,96 patients with acute coronary syndrome were admitted in our hospital from December 2014 to September 2016.In the prospectively study,they were randomized into Atorvastatin group(Atorvastatin 20 mg daily,n =48) and Simvastatin group(Simvastatin 40 mg daily,n=48),and serum levels of hs CRP,lipids and changes in myocardial function were detected and compared between two groups before and after treatment.Results The serum levels of hs-CRP and lipids were significantly lower in Atorvastatin group than in Simvastatin group at 8 weeks after treatment(P＜0.05).At the end of the treatment,the levels of left ventricular reject fraction and left ventricular end-diastolic volume index were improved (all P ＜ 0.05) in two groups,but significantly higher in Atorvastatin group [(44.8 ± 6.3) ％ and (62.7 ± 10.4)] than in Simvastatin group [(48.9 ± 6.9) ％ and (67.9 ± 10.5) respectively,all P ＜ 0.05).Conclusions Simvastatin and Atorvastatin can effectively promote the decrease in levels of blood lipids and inflammatory reaction,and help to improve the myocardial function in patients with acute coronary syndrome,but Atorvastatin effects are more significant.

ObjectiveTo investigate the expression of integrin β1 during retinal detachment and reattachment of rabbits.Methods24 rabbits were used to make retinal detachment and reattachment model by using hyaluronidase and micropipette. The expression of integrin β1 were observed with hybridization in situ.ResultsThe expression of integrin β1 in reattached retina was lower than that in detached retina.ConclusionRetinal reattachment may inhibit the development of proliferative vireoretinopathy.

ObjectiveTo determine the source of IL-6 in detached retina and the change of IL-6 level in detached and reattached retina.MethodsRetinas of SD rat were examined after subretinal injection of 1.4% Healon GV at different period of time, and the level of IL-6 in detached and reattached retina were detected by radio-immune histochemistry method. Wax-embeded sections were labeled with IL-6 antibody to determine the location of IL-6.ResultsDetached retina with normal vitreous and inner limiting membrane could only induce the subretinal fibrosis. This kind of fibrosis reached to its peak at 10th day and then remolded with time. Retinal pigment epithelial (RPE) cell, Muller cell, endothelial cell, glial cell were labled with IL-6, and the level of IL-6 in neuro-retina reached to its peak at 3rd-4th day and then downed to normal within a few days. The level of IL-6 in reattached retina was lower than in detached retina. The expression of IL-6 in RPE of detached area was stronger than in attached area.ConclusionIL-6 takes active part in wound healing process induced by the separation of RPE and neuro-retina. Reattachment can lower the expression of IL-6 in retina.

AIM: To observe the clinical efficacy of Dengzhan Shengmai Capsules(Herba Erigerontis,Radix et Rhizoma Ginseng,Radix Ophiopogouis,Fructus Schisandrae chinensis) in improving type 2 diabetes insulin resistance. METHODS: 98 patients were randomly divided into two groups: the control group(50 cases) were treated with conventional therapy,the treatment group(48 cases) were treated with Dengzhan Shengmai Capsules based on conventional therapy.These two groups were all treated for 2 months.FPG,FINS,2hPG,HbA_1C and ISI were observed before and after treatment. RESULTS: The total effects of the treatment group(91.67%) was higher than that of the control group(40.00%)(P

Objective:To observe the therapeutic effect of acupuncture-moxibustion at different intervals on persistent allergic rhinitis. Methods: A total of 90 patients conforming to the inclusion criteria were randomized into three groups named A, B and C by randomized block method. Patients in all three groups received the same treatment of acupuncture and herbal cake-partitioned moxibustion at the same acupoints, while the treatment frequency was different. Patients in group A received the treatment once a week, group B twice a week and group C three times a week, and all the treatment lasted for 4 weeks. The total nasal symptom score (TNSS), total ocular symptom score (TOSS) and Sino-nasal outcome test-20 (SNOT-20) were evaluated before and after treatment. The self-rating score of symptoms was evaluated during treatment and 2 weeks after treatment. Results: The total effective rate was 80.0% in group A, 93.3% in group B, and 100.0% in group C. The total effective rate in group A was statistically different from that in group B and group C (both P＜0.05), but there was no significant inter-group difference in total effective rate between group B and group C (P＞0.05). After treatment, scores of TNSS, TOSS and SNOT-20 in all three groups dropped significantly, and statistically different from those before treatment (all P＜0.05); between-group comparison showed group B and group C decreased more obvious than group A (all P＜0.05). In self-rating score of symptoms, there were no inter-group statistically significant differences in the first 3-week treatment (all P＞0.05); after 4-week treatment, the score in group A was higher than that in group B and group C, and showed statistical significant (both P＜0.05); at 2 weeks after treatment, the score in group A was higher than that in group B and group C based on an everyday record, showing statistical significance (both P＜0.05). At the 11th day after treatment, the score in group B was higher than that in group C (P＜0.05). There were no significant differences between group B and group C at other time points (all P＞0.05). Conclusion: All three protocols are effective for allergic rhinitis. With the increase of treatment frequency, the therapeutic efficacy with a treatment frequency of twice a week and three times a week is superior to that of once a week. Frequency of three times a week has a better long-term effect than once and twice a week, together with the least fluctuation of symptoms.

Abnormal proliferation of vascular smooth muscle cells (VSMCs) plays an important role in several pathological processes of cardiovascular diseases. In this study, the effects of XCT790, a potent and selective inverse agonist of estrogen-related receptor alpha (ERRalpha), on rat VSMCs proliferation and related signal pathways were investigated. The proliferative activity of VSMCs was determined by CCK-8 assay. The mRNA levels of ERRalpha, PGC-1alpha, OPN and MCAD were assayed by RT-PCR. The protein levels of ERRalpha, ERK2 and p-ERK1/2 were evaluated by Western blotting. ELISA was used to assess the protein expression of VEGF. The results showed that XCT790 (5-20 micromol x L(-1)) inhibited rat VSMCs proliferation, and the expression of ERRalpha and its target genes, as well as p-ERK1/2, were also inhibited. XCT790 inhibited VSMCs proliferation in a dose-dependent manner at the dose range from 5 to 20 micromol x L(-1) and in a time-dependent manner at the dose range from 10 to 20 micromol x L(-1). These findings demonstrate that XCT790 inhibits rat VSMCs proliferation by down-regulating the gene level of ERRalpha and thus inhibiting the ERK signal pathway, suggesting that ERRalpha may be a novel potential target for therapeutic approaches to inhibit VSMCs proliferation, which plays an important role in several cardiovascular diseases.
