Objective To understand the working pressure source of obstetric nurses in Kunming through a sample survey study, so as to provide a reference for obstetric nurses to adjust self-psychology and for clinical managers to relieve working pressure on obstetric nurses. Methods We gave a sampling survey on 249 obstetric nurses in provincial,municipal and private hospitals,and usedChinese nurse job stress scaleto collect the data for statistical analysis. Results Kunming obstetric nurses' working pressure mainly came from the workload and time allocation. The ten stressors with highest score of pressure were frequent highest score, too much work, low welfare benefits,too much useless paperwork, low social status,worry about mistakes at work, too high expectation of patients,too much non-nursing work, nursing work is not accepted by patients and their families, few nurses to work. Age,title and nature of the preparation had no effect on work stress. Public hospital nurses' working pressure was significantly greater than private hospitals. Conclusion Working pressure sources of obstetric nureses in Kuming are too much night shift,too much work,welfare berfits useless paperwork,social status,mistakes at work, patients expectation work is not accopted and staffing Hospital management and nuusing managers should doploy rationally human resoures on obstteic area,reasorabal scheduling.

Objective To evaluate the effect of ?-lipoic acid(ALA)as a antioxidant on the histomorphologic changes of the kidney in type 2 diabetic Goto Kakisaki rats.Methods Four healthy Wistar rats(normal control group)and 10 GK rats were divided randomly into two groups:diabetic control group and lipoic acid-treatment diabetic group(?-lipoic acid 35 mg/kg intraperitoneal injection qd alt),who were both fed for 12 weeks.Indexes of oxidative stress of kidney were measured.Sections of renal tissue were evaluated using both a light and electron microscope to assess histomorphologic changes.Paraffin sections of the left kidneys were prepared and stained with H&E,PAS and Masson stains to compare the histomorphologic changes.The image analysis software of Motic Image Advanced 3.1 was used to measure the area of glomerulus and mesangial region,and the thickness of the glomerular basement membrane(GBM).Results Compared with normal control group,there were significant decreases in GSH,SOD,VitC and VitE levels in diabetic control group.The kidneys of the normal control group exhibited normal cortical morphology as determined by light microscope.Mild glomerulosclerosis,characterized by widening of the mesangial region,mesangial expansion and intercapillary cells proliferation,and GBM thickening under electron microscope were observed in the diabetic control group.In the ALA-treatment group,all the above pathological changes were alleviated.Conclusion In the kidney of type 2 diabetic rat,there exists oxidative stress which is associated with diabetic nephropathy.?-Lipoic acid can alleviate the abnormal histomorphologic changes of the kidney via antioxidative effects.

Purpose To establish rabbit VX2 tumor model and to explore the relation between perfusion parameters and the expression of the VEGF in the portal vein VX2 implanting tumor emboli. Materials and Methods VX2 tumor was implanted in the portal vein of eight experimental rabbits. Multi-slice CT (MSCT) perfusion scan was performed after tumor formation to measure and compare portal vein tumor thrombus, hepatic blood lfow (HBF) near tumor foci and far away from tumor foci, hepatic blood volume (HBV), probability of surface area product (PS) and mean transit time (MTT). The VX2 tumor emboli were then resected to analyze the relationship between the liver perfusion parameters and VEGF expression using immunohistochemical method. Results MSCT liver perfusion parameters were not statistically signiifcant between foci close to or far away from the tumor (P>0.05). The HBF, HBV and PS within the tumor emboli were higher than that in hepatic parenchyma (P<0.05) and the MTT was higher (P<0.05). There was positive correlation (r=0.711, 0.646 and 0.626, P<0.05) between the HBF, HBV and PS of portal vein VX2 tumor emboli and VEGF expression, and there was negative correlation between MTT and VEGF expression (r=-0.565, P<0.05). Conclusion MSCT perfusion parameters in the portal vein VX2 implanting tumor emboli and the expression of VEGF are positively related. MSCT can evaluate the angiogenesis of portal vein VX2 implanting tumor emboli.

Objective To observe changes of motilin(MTL) levels in gastric body, duodenum and plasma in rat model of acute incisional pain.Methods A total of 156 healthy male adult SD rats,weighing 180-220 g,were randomized into two groups:control group (group C,n=78) and incisional pain group (group P,n=78),Rats in P group received incision on the right plantaris. Values of paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) at dif?ferent time points of 24 hours before operation (T0) and 1 hour (T1),6 hours (T2),24 hours(T3),48 hours (T4) and 72 hours (T5) after operation were measured in six rats chosen randomly from each group. Twelve rats were chosen from each group at T 0-5, and sacrificed. The MTL levels in plasma, the mucosal tissues of gastric body and duodenum were detected by ELISA. Re?sults Compared with group C, PWMT and PWTL were significantly decreased at T1-4 in group P. The MTL levels were sig?nificantly decreased in plasma and gastric body (P<0.05).The MTL level was significantly increased at T1-4 in duodenum (P<0.05),and no significant changes were found at T0 and T5 in P group(P>0.05). The plasma MTL levels were positively correlated with PWMT and PWTL (r=0.952,r=0.879,respectively,P<0.01) in P group. The MTL levels in gastric body were positively correlated with PWMT and PWTL(r=0.970,r=0.931,respectively,P<0.01) in P group. The MTL levels were neg?atively correlated with PWMT and PWTL(r=-0.991,r=-0.975,respectively,P<0.01) in duodenum in P group. Conclu?sion The MTL levels in plasma and gastric body are decreased in rat model of acute incisional pain, and increased in duo?denum.
