Conclusion The nursing intervention can significantly improve lung function and quality of life in elderly chronic obstructive pulmonary disease.

Objective To observe the expression of inducible factor 1(HIF‐1) ,vascular endothelial growth factor(VEGF) and miRNA‐210 and explore the regulatory mechanism after unilateral ureteral occlusion (UUO) .Methods UUO models are made by ligation unilateral ureteral with silk ,and they were divided into sham group and UUO group .All the mice were sacrificed by cer‐vical dislocation after 2 ,5 ,9 and 14 d of UUO .The kidney samples were examined for HIF‐1 mRNA ,VEGF mRNA and miRNA‐210 by quantitative real time reverse transcription polymerase chain reaction (RT‐PCR) ,and HIF‐1 protein by Western blot . Results The expression level of HIF‐1 mRNA was gradually raised after UUO (P<0 .05) ,and compared with the sham group ,the expression level of VEGF mRNA and miRNA‐210 were up regulated after 2 d of UUO and down regulated after 5 ,9 and 14 d of UUO compared with the sham group (P<0 .05);the expression level of HIF‐1 protein increased after UUO compared to the sham group .Conclusion The results of the level of HIF‐1 protein increased and VEGF mRNA and miRNA‐210 were up regulated ,which might be related to the adaptive response of kidney hypoxia and ischemia after UUO .

Objective To observe the relationship between psychological factor(anxiety and depression) and postpartum hemorrhage?mode and duration of labor. Methods Ninety two healthy nulliparas who had no gist of cesarean section were involved in our study. Their psychosis were evaluated with Self-rating Anxiety Scale(SAS) and Self-rating Depression Scale(SDS),according to which they were divided into two groups:high-score group and low-score group.All women were not interfered during the courses of delivery. Mode, duration of labor and postpartum hemorrhage were observed. Results Among the 92 nulliparas observed, the spontaneous delivery rate was 86.96% (80 cases) and the postpartum hemorrhage rate was 10% (8 cases). The scores of SAS and SDS of the low educational level group, the spontaneous group or the non-hemorrhage group were significantly lower than those of the high educational level group, the dystocia group or the hemorrhage group respectively. Moreover, the duration of first and the second stage of the high SAS score group or the high SDS score group was significantly longer than that of the low SAS score group or the low SDS score group,P

Objective To study the prevention and treatment effect of ω-3 fatty acids on intestinal mucosa in critical illness. Methods Forty patients including severe trauma, infection shock were enrolled as experimental group, while 30 healthy people as control group. At the same time, the patients in expermental group were randomly divided into group A and group B(20 cases each). While the patients were. Treated with low calorie parenteral nutrition totally, those in group A received ω-3 fatty acids additionally. The plasma concentrations of dimnine oxidase (DAO), endotoxin were detected by spectrophotography, and TNF-α was detected by ELISA. Results After treatment the concentration of DAO, endotoxin, TNF-α in group A and that of endotoxin in group B decreased significantly (P<0.05 ). While there was no significant difference of endotoxin levels between group A and group B. After therapy, DAO and TNF-α levels in group A were sig-nificantly lower than those in group B (P<0.05 ). The concentrations of DAO and TNF-α in group B were also significantly higher than those in control group (P<0.05). Conclusion ω-3 fatty acids can prevent and treat critical intestinal mucosa effectively.

Objective To investigate the short-term clinical efficacy and complication of esophageal cancer patients with two-field lymph node dissection by thoracolaparoscopic esophagectomy surgery and open surgery. Methods One hundred and fifty esophageal cancer patients with two-field lymph node dissection were selected, and they were divided into control group (using open surgery, 75 cases) and observation group (using thoracolaparoscopic esophagectomy surgery, 75 cases) by random digits table method. The operation time, bleeding amount, hospital staying time, number of lymph node dissection, reoperation rate, intensive care unit (ICU) transferring rate and postoperative complication were compared. Results There was no statistical difference in operation time between 2 groups ( P>0.05). The bleeding amount and hospital staying time in observation group were significantly lower than those in control group: (210.33 ± 30.71) ml vs. (254.59±35.28) ml and (8.45±1.52) d vs. (11.61±2.08) d, there were statistical differences (P<0.05). The number of chest lymph node dissection in observation group were significantly higher than those in control group:(17.20±4.06) pieces vs. (10.44±2.65) pieces, and there was statistical difference (P<0.05). There were no statistical differences in reoperation rate and ICU transferring rate between 2 groups ( P>0.05). There were no statistical differences in incidences of hoarseness and anastomotic stenosis between 2 groups ( P>0.05). The incidences of pulmonary infection and arrhythmia in observation group were significantly lower than those in control group:17.33%(13/75) vs. 30.67%(23/75) and 2.67%(2/75) vs. 14.67%(11/75), and there were statistical differences (P<0.05). Conclusion Compared with open surgery, thoracolaparoscopic esophagectomy surgery with two-field lymph node dissection for esophageal cancer patients can effectively reduce the degree of operative trauma, accelerate postoperative rehabilitation process, improve the effects of lymph node dissection, and reduce postoperative complication risk.

Objective To explore the long-term effect of open reduction and internal fixation for the treatment of displaced acetabular fracture,and analyze the influence of risk factors.Methods The clinical data of 62 patients with acetabular fracture from August 2005 to February 2009 was analyzed retrospectively.All the cases were treated with open reduction and internal fixation.The long-term effect and related risk factors were analyzed.Results All the cases were followed up for 24-52(38.8 ± 2.6) months.According to the Matta standard of replacement of fracture,there were 43 cases with anatomic reduction,14 eases with satisfactory reduction,5 cases with unsatisfactory reduction.Fracture union was obtained in all the patients.Based on the modified Merled' Aubigne -Postel clinical grading system,the result was excellent and good in 50 patients,fair and poor in 12 patients,with excellent rate of 80.65％ (50/62).Postoperative complications including traumatic arthritis were seen in 7 patients,heterotopic ossification in 3 patients and femoral head avascular necrosis in 1 patient.The related risk factors of clinical results of displaced acetabular fracture were age,Letournel-Judet fracture type,operation time,cartilage surface damage of the femoral head and quality of reduction (P ＜ 0.05 ).However,gender,AO fracture type,surgical approach and hip dislocation were not affecting factors of the acetabular fracture(P ＞ 0.05 ).Conclusions Open reduction and internal fixation can result in a satisfactory clinical outcome.Age,Letournel-Judet fracture type,operation time,cartilage surface damage of the femoral head and quality of reduction are independent risk factors affecting postoperative long-term functional outcomes.
