Objective To evaluate the role of intercellular gap junction in lung injury induced by hemorrhagic shock and resuscitation in rabbits. Methods Twenty-four healthy rabbits of both sexes weighing 1.5-2.2 kg were used in this study. The animals were anesthetized with iv 3% pentobarbital 30 mg/kg,tracheostomized and mechanically ventilated. Femoral artery was cannulated for MAP monitoring, blood-letting.Right external jugular vein was cannulated for fluid infusion. Hemorrhagic shock was induced according to the method described by Wiggers. MAP was maintained at 35-40 mm Hg for 60 min. The animals were then randomly divided into 2 groups (n = 12 each):traditional treatment group (group A) and octanol group (group B). Both groups received rapid iv infusion of lactated Ringer's solution (LR solution) 1.5 ml·kg-1 ·min-1 for 30 min (T3 ).In group B 99.5% octanol (a specific gap junction inhibitor) 5 mmol/kg was injected intraperitoneally (IP) in addition to iv LR solution infusion. Thirty minutes later the animals were resuscitated with infusion of the blood withdrawn and LR solution (the volume was equal to the volume of blood loss). Then LR solution was infused iv at 2.5 ml· kg-1 · h-1 for 150 min ( T4 ). Left ventricular systolic pressure (LVSP) and HR were recorded before blood letting (T1), immediately after successful establishment of the model (T2), and at T3 and T4. The mortality during resuscitation was calculated. The animals were killed at T4. Blood samples were taken from femoral artery for determination of the serum protein concentration. The lungs were removed. The left lower lobe was lavnged. The protein concentration in broncho-alveolar lavage fluid (BALF) was measured. Lung permeability index (LPI) was calculated (LPI = protein concentration in BALF protein concentration in serum). Na+-K+-ATPase and Ca2+-ATPase activities and W/D lung weight ratio were determined and microscopic examination was performed. Results HR was significantly lower at T3 and T4 and LVSP higher at T4 in group B than in group A. The pulmonary permeability index, W/D lung weight ratio and mortality were significantly lower and the activities of Ns+-K+-ATPase and Ca2+ -ATPase were significantly higher in group B than in group A. The lung tissue danage was significantly ameliorated in group B. Conclusion Intercellular gap junction is involved in the development of lung injury induced by hemorrhagic shock and resuscitation in rabbits.

Objective To summarize the experience of nursing cancer patients with Wernicke encephalopathy (WE) after gastrointestinal surgery. Method The clinical data of 6 patients with WE after gastrointestinal surgery in our hospital from January 2005 to June 2015 were retrospectively analyzed to summarize the nursing strategies. Results All the 6 patients showed mental changes of different types, 5 patients developed with ocular manifestations and one patient with ataxia. Only one patient showed the classic triad of the disease at clinical presentation. All the 6 patients had characteristic manifestations on cranial MRI and received thiamine (vitamin B1) at diagnosis. Four patients were completely recovered and 2 were partially recovered. Conclusion Timely sufficient thiamine supplementation during the perioperative period is the key to prevent and treat WE in the patients with gastrointestinal cancer. Careful observation of the patients′ mental state and the effective nursing for the special classic triad of the disease are critical for a better prognosis.

Objective To investigate the correlation between job stressors, resilience and turnover intention among nurses in Beijing. Methods A total of 419 nurses from top three hospitals in Beijing were investigated with the Job Pressure Scale, Resilience Scale and Turnover Intention Questionnaire from April to May 2015. Results The major job stressors in clinical nurses were as follows: problems of the nursing profession and work, time allocation and workload, patient care, working conditions and environment, management and interpersonal relationship. The total score of job stressors was 2.15 ± 0.38. Job stressors of nurses was negatively correlated with resilience (r =-0.222, P < 0.01), positively correlated with turnover intention (r=0.221, P<0.01). Conclusions Resilience plays an important role in releasing pressure of nurses. Enhancement of resilience in nurses is an important way to relieve job stress of nurses as it can reduce the turnover intention.

Objective To observe the serum level of C-reactive protein(CRP) in transient ischemic attack(TIA) patients,and to assess the correlation between CRP and other dangerous factors of cerebral infarction.Methods 102 TIA patients were divided into two groups: TIA deteriorated into cerebral infarction in two weeks(group A,n=40) and TIA could be relieved in two weeks(group B,n=62).Many factors were measured within 24 h,such as CRP,BP,BS,FIB,TC,TG,HDL-L,and LDL-L.67 healthy subjects were usded as control group.Relative analysis was performed between CRP and 8 parameters mentioned above.Results ①The serum CRP level of TIA patients was higher than that of healthy controls(P

Objective We aimed to explore the experience of posttraumatic growth in patients with cervical cancer who had a hysterectomy at the childbearing age.Methods The phenomenological methodology was used in the study.An in-depth interview was conducted among 12 patients chosen by purposive sampling method.Results Through careful analysis and collation,three themes were identified:smashing the original assumption,searching the meaning of existence and rebuilding the new cognitive schemata.The experience of patients' was conformed to the model which was put forward by Tedeschi,and the theme changes in personal relationships,personal strength,altruism born from sufferings and new philosophy of life were conformed to theoretical connotation of PTG.Conclusions Clinical medical staff should update psychological nursing concept timely and taking advantages of PTG to help patients pass through their difficult period.

To study the anti-inflammatory activity of glycyrrhizin acid, ligustrazine and puerarin. In the study, the liquichip-based high-throughput synchronous detection technique for 23 inflammatory factors, uniform design, comprehensive weight method were adopted to study the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin in inhibiting the expression of lipopolysaccharide (LPS)-induced RAW264. 7 cells and multiple inflammatory cytokines. In the study, the uniform design table U₉ (9³) was adopted to design doses of glycyrrhizin acid, ligustrazine and puerarin. The liquichip technique was used to detect the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin on the 23 cytokines expressed in LPS-induced mouse macrophage RAW264. 7 inflammation model. The traditional Chinese medicine component optimization software and the improved least angle regression algorithm were used to analyze the dose-effect relationship among the three components and the cytokine inhibition rate and produce the regression equation. The comprehensive weight method was applied to get the optimal dose ratio of glycyrrhizic acid, ligustrazine and puerarin with highest efficacy of 25:2:13 and verify the optimal dose ratio. The verification results were consistent with the prediction trend, indicating the accuracy of the mathematical model for predicting the experiment. The experimental results showed the multi-target and multi-level efficacies of glycyrrhizic acid, ligustrazine and puerarin and the high anti-inflammatory activity of their combined administration, which provides powerful basis for subsequent drug development.
