Objective To investigate the relation among clinical nurses′resilience, emotional, the pressure load and self-efficacy with the 10-item Connor-Davidson Resilience Scale. Methods A total of 449 nurse in Guangzhou were recruited to investigate by 10-item Connor-Davidson Resilience Scale (CD-RISC-10), Kessler 10 Scale (K10), General Self-Efficacy Scale (GSES), Chinese Stress Overload Scale (SOS). Results The average score was 23.6±6.7 for CD-RISC-10 , 24.4±8.2 for K10,24.7±5.7 for GSES , 63.3 ±16.6 for SOS ,and the individual vulnerability scoring was (31.2±10.0) points, events load was (32.0±7.5) points. High mental toughness of nurses in general self-efficacy scores higher than that of low mental toughness group (t=-8.53, P<0.01), in the K10 dated, S0S scores were lower than low mental toughness group (t=11.23, 7.70, P<0.01). Nurse relevant regression analysis results showed that gender, general self-efficacy, K10 dated, SOS as the main factors influencing nurses mental toughness, could explain 40%of variances. Conclusions The CD-RISC-10 can better reflect the level of clinical nurses′resilience, and the gender, self-efficacy were the main effects, as well as effectively predict the nurses′emotional distress and stress level. However how to improve the toughness of the clinical nurses need more research.

Objective To observe the effect of five-tone music therapy on relieving anxiety and depression and on improving the quality of life of patients receiving chemotherapy after gastric cancer radical surgery.Methods Ninety anxiety and depression in-patients treated with chemotherapy after gastric cancer radical surgery were randomly divided into observation group and control group,45 cases in each group.Patients of the two groups were treated with the same chemotherapy regimen and nursing,and additionally,the observation group was given fivetone musie therapy and the control group was given conventional music therapy.The intervention effects were evaluated by scoring with Self-rating Anxiety Scale (SAS),Self-rating Depression Scale (SDS) and questionnaire for the quality of life of gastric cancer patients (QLQ-STO22) at admission time and when discharging from hospital.Results The SAS and SDS standard scores and the scores of each dimension of QLQ-STO22 in the observation group were markedly decreased after intervention,the differences being statistically significant (P ＜ 0.01 compared with those before intervention).And the SAS and SDS standard scores of the observation group after intervention were lower than those of the control group (P ＜ 0.01).In the aspects of quality of life,the scores of all dimension of QLQ-STO22 except taste,appearance and hair loss in the observation group were lower than those in the control group (P ＜ O.05).Conclusion Five-tone music therapy is effective on relieving anxiety and depression and on improving the quality of life of patients receiving chemotherapy after gastric cancer radical surgery.

Objective To observe the changes in estrous cycle and vaginal smears in ovarectomized NOD/SCID mice.Methods To continuously observe the estrous cycle time by vaginal smears of NOD/SCID mice in consecutive nine days, twice daily.After ovariectomy, the changes of estrous cycle were observed by vaginal smears for 7 days.Results The estrous cycle in NOD/SCID mice was 4-6 days.Regular estrous mice accounted for 80%.There was no significant correlation between vaginal opening and estrous cycle status.After ovariectomy, the vaginal smears showed characteristics of metestrus or diestrus.Conclusions Vaginal smear cytology can be used to determine the estrous cycle and characteris-tics of NOD/SCID female mice.The ovariectomized operation of NOD/SCID female mice is effective.

Objective To investigate the level of caregivers′burden and the coping style among parents of cancer children. Methods Totally, 229 parents of cancer children participated in the investigation by Chinese version of zarit burden interview (ZBI), Chinese version of coping health inventory for parents (CHIP) and self-designed general information questionnaire. The associations between caregivers′burden and coping styles were tested by Spearman correlation analysis. Results The caregiver′s burden on the parents was in the middle level with a total score of (30.50 ± 12.24). The coping style the parents took most frequently was to unite the family and keep a positive attitude and regard it as most effective. The caregiver′s burden was negatively associated with the positive coping style . Conclusion The parents of cancerous children suffer from middle level of burden . Nurses should assess the caregiver′s burden, provide targeted interventions to relieve it, help the to establish effective coping style and change their psychological and mental state and ultimately improve their quality of life.

AIM: To explore the expressive role of lipoprotein-associated phospholipase A_2, high sensitive C-reactive protein and matrix metalloproteinase-9 in vulnerable atherosclerotic plaques in a rabbit model. METHODS: Forty eight New Zealand white male rabbits were randomly divided into 4 groups (12 rabbits each): control group, stable plaque group, p53 group, and p53+drug group. Rabbits in control group were fed with a regular diet and underwent sham operation. Rabbits in stable plaque group, p53 group and p53+drug group underwent balloon induced arterial wall injury and then were fed on a diet with 1% cholesterol. The animals were all fed for 3 months, then the rabbits in p53 group and p53+drug group underwent Ad5-CMV p53 transfection at 10th week. Before killed, the animals in p53+drug group underwent pharmacological triggering with Russell's viper venom (RVV) and histamine to induce the rupture of the atherosclerotic plaques. At the 1st day and before sacrifice, the serum was collected for measuring Lp-PLA_2, hs-CRP, MMP-9, HDL, LDL and VLDL. The expressions of Lp-PLA_2, hs-CRP and MMP-9 in tissues were determined by the methods of hybridization and immunohistochemistry. RESULTS: At the end of 12th week, the serum and tissue levels of Lp-PLA_2 and MMP-9 in stable plaque group, p53 group and p53+drug group were significant different from those in control group and in each group at the first day (P<0.05). The serum levels of Lp-PLA_2 and hs-CRP in p53 group and p53+drug group were significantly higher than those in control group and stable group (P<0.05). The serum levels of Lp-PLA_2, hs-CRP and MMP-9 were all significantly different between p53 group and p53+drug group (P<0.05). At the end of 12th week, pathological results showed that 4 groups were normal artery, stable plaque, vulnerable plaque and rupture plaque, respectively. The fabric cap was thicker in plaque groups than that in normal group (P<0.05). The rupture and formation of thrombus were more significant in p53+drug group than those in p53 group. The serum level of Lp-PLA_2 had negative interrelated relationship with fabric cap in plaque groups (r=-0.710, P<0.01), and hs-CRP, MMP-9 had no interrelated relationships with fabric cap in plaque groups. CONCLUSION: Base on the successful establishment of the atherosclerotic plaque animal model, serum Lp-PLA_2 shows better interrelated relationships to plaques stability. Combination with hs-CRP and MMP-9, we can exactly evaluate the nature of plaques.

Objective: To investigate the safety and efficacy of the Weitan Waifu patch on the postsurgical gastroparesis syndrome (PGS) of gastrointestinal cancer. Methods: The multi-center, double-blind, randomized controlled trial was conducted with superiority design. Patients with PGS of gastrointestinal cancer diagnosed in 4 AAA hospitals and the abdominal symptom manifested as cold syndrome by Chinese local syndrome differentiation were recruited. These patients were randomly divided into two groups according to 1∶1 proportion. Placebo or Weitan Waifu patch was applied in control group or intervention group, respectively, based on the basic treatments, including nutrition support, gastrointestinal decompression, promoting gastric dynamics medicine.Two acupuncture points (Zhongwan and Shenque) were stuck with placebo in control group or patch in treatment group. The intervention course was 14 days or reached the effective standard. Results: From July 15, 2013 to Jun 3, 2015, 128 participants were recruited and 120 eligible cases were included in the full analysis set (FAS), and 60 cases in each group. 88 cases were included in the per-protocol set (PPS), including 45 cases in the treatment group and 43 cases in the control group. In the FAS, the clinical effective rate in the treatment group was 68.3%, significantly superior than 41.7% of the control group (P=0.003). The medium time of effective therapy in the treatment group was 8 days, significantly shorter than 10 days in the control group (P=0.017). In the FAS, 3 adverse events occurred in the treatment group, including mild to moderate decrustation, pruritus and nausea. The incidence rate of adverse events was 5.0% (3/60) and these symptoms were spontaneously remitted after drug withdrawal. No severe adverse events were observed in the control group. There was no significant difference between these two groups (P=0.244). Conclusion: Weitan Waifu patch is a safely and effectively therapeutic method for patients with PGS (cold syndrome) of gastroenterological cancer.
