Objective To study the effect of macrophage, its stimulating factor, granulocyte macrophage colony-stimulating factor (GM-CSF), the combination of GM-CSF and macrophage on the survival of rat deep epigastric perforator flap (DEP). Methods The stable animal model of DEP flap in Sprague-Dawley rat mimicing human deep inferior epigastric perforator flap in breast reconstruction was established. The rats were treated with subcutaneous injection of recombined rat GM-CSF or rat peritoneal macrophages, respectively, or combination of GM-CSF/ Macrophages. Normal saline was used as parallel negative control. The rats were sacrificed and flap specimens were harvested on day 7 after operation, the flaps survival area were measured by the method of rubbings and the survival proportion of flaps were calculated, Von Will brand factor were detected by immunohistochemistry and microvessel density (MVD), and were calculated with microscopic study, and collagen were stained and quantified by Masson staining. Results Survival proportion of flaps in group GM-CSF (53.08% ± 8. 76% ) was not different with that in macrophages group (47. 95% ± 4. 92% ), and both of these two groups were significantly higher than parallel negative control group (43.28% ± 5.27% ) but significantly lower than combination GM-CSF/ macrophages group ( 61.68% ± 6. 60% ). For MVD, flap in GM-CSF group ( 24. 82 ± 4. 18 ) was not significantly different with macrophages group (24.30 ± 3.02 ), and both of these two groups were significantly higher than group parallel negative control (21.37 ± 2.65 ) but significantly lower than combination GM-CSF/macrophages group ( 29. 82 ± 4. 74). Collagen deposition in the flaps in GM-CSF group (17. 25% ± 2. 85% ) were significantly higher than parallel negative control group (14.41% ± 2. 89% ), macrophages group ( 12. 69% ± 3.55% ) were lower than parallel negative control group but there was no significant difference. That in combination GM-CSF/macrophages group (20.31% ± 3.01% )was significantly higher than GM-CSF group ( P < 0. 05 ). Conclusion Treatment with rat GM-CSF or macrophage can significantly promote the survival of the flaps. Combined application of GM-CSF and macrophage could synergetically promote the survival of the flaps, the vasculogenesis and the collagen deposition.

Objective To investigate the value of critical scoring system in the treatment of multiple organ dysfunction after exposure to poisoning by analyzing 3 cases of industrial organic fluorine gas poisoning.Methods Clinical data of symptoms,signs,treatments,outcome and the changes in the scores as APACHE Ⅱ,SOFA,MODS were collected,the differences among the patients were compared and the relevance was analyzed.Results The first APACHE Ⅱ was 19-26.Scores of case 1 in the three scoring systems constantly increased and different components were found,with the suggestion of sequential organ dysfunction.Other two patients' scores decreased and survived without complications.Conclusiorn Multiple critical scoring systems can be used to evaluate the outcome of multiple organ dysfunction due to organic fluorine gas poisoning.System evaluation and individualized treatment are both important.More studies can help to set up a special critical scoring system.

Objective:To reports the nursing care of a patient with superior mesenteric artery syndrome after posterior spinal correction for adolescent idiopathic scoliosis.Methods:While in hospital, conservative treatment requires fasting and water deprivation, gastrointestinal decompression. Combined with perioperative nursing measures of spinal orthopedics, the nursing focus of patients during hospitalization includes: enteral and parenteral nutrition, designed the condition record sheet, and dynamically monitor the patient′s condition; personalized guidance about function exercise was gibien.In addition,continuous care after discharge were provided through health education before discharge and post-discharge follow-up.Results:After the implementation of the nursing measures, the patient recovered well after surgery, the symptoms of superior mesenteric artery syndrome were effectively controlled, and the patient resumed eating through the mouth. Two months after discharge, the patient gained 4kg of body weight.Conclusion:The treatment and nursing of superior mesenteric artery syndrome is a long-term process, nurses should place emphasis on observation and nutrition support, and also the patient psychological care.

Objective To explore the influence of health education and treatment compliance on COPD patients' outcome.Methods 258 subjects (186 males,72 females,average age 75.2±8.5 years) were enrolled from patients diagnosed with COPD between June 2013 to June 2014 in huashan hospital north compus.Study began in July 2014,health condition assessment and grading、telephone follow-up and education were performed once every half a year together with COPD lectures,the number of patients participated in education sessions,and status of smoking cessation,exercise\home oxygen therapy and medication were recorded as indicators for health education compliance.Clinic/hospital stay and cost,condition change were also recorded.The study ended in December 2015 with final assessments of conditions and classification of patient outcome.Multiple logistic regression was used to analyze factors influencing the COPD patient's outcome;Independent sample t test was applied to compare different compliance in patients with outpatient and hospitalization per-time cost difference.Results Higher reimbursement ratio,the better adherence for health education,no complications and the low grade of disease classification at the beginning of the study were protective factors (OR=10.35,2.147,5.791,4.51,P＜0.05);Underweight to normal weight,5 times or more acute attacks during during the study,poor health education compliance were risk factors for disease progression (OR=0.031,0.131,0.010,P＜ 0.05);Never exercise and never participating in health education management are the risk of illness/death((OR=6.793,P=0.005,95％CI:1.766～26.125) vs.(OR=11.872,P=0.002,95％CI:2.525～55.815));for mild COPD patients,these never participating in health education management had a higher per hospitalization than patients with health education management (6 619 yuan,t=2.681,P=0.010).The outpatient cost of more severe COPD patients who are smoking or quitted smoking in less than 5 years was higher than these quitted smoking more than 5 years (985 yuan,t=-2.225,P=0.028).Conclusions Health education management can help medical staff to provide guidance to patients to quit smoking,encouraging the regular use of home oxygen therapy,doing more exercise,taking prescription of preventive drugs,these will in turn improve patient compliance for disease control and prevention.These efforts can effectively slow disease progression and improve patient outcomes,reduce medical costs,reduce the burden of the family and society.
