Objective This study was carried out to investigate the effect of myocardial insulin resistance on expression of p38 mitogen-activated protein kinase (MAPK) in ischemic heart failure in rat.Methods Male sprague-dawley rats were subjected either to ligation of the left anterior descending artery (LAD) (n =24) or to sham operation (n =24).After two weeks,cardiac size and function were determined by echocardiography.Glucose and fatty acid (FAO) oxidation rates as well as insulin response were measured in the isolated working heart.The protein expression of p38MAPK was evaluated by Western blotting.Results The infarcted hearts were dilated and had a reduced ejection fraction (ejection fraction ＜0.50).The basal glucose oxidation was preserved,but the fatty acid oxidation was significantly reduced.Insulin effect on substrate oxidation was significantly impaired for both the decrease in fatty acid oxidation and the increase in glucose oxidation.The protein expression of p38MAPK in infracted hearts wasfisigni cantly reduced(P＜0.05).Condusion Myocardial infarction in rats caused partial insulin resistance at the level of substrate oxidation,which was associated with cardiac contractile dysfunction and the expression of p38MAPK.

Objective To investigate the diagnosis of intracranial artery fenestration and its other vascular anomalies with CT angiography ( CTA ) . Methods The image data of 653 patients examined with head CTA and 39 patients diagnosed as intracranial artery fenestration in Zhongshan Hospital Affiliated to Sun Yat-sen University from January 2013 to January 2014 were analyzed retrospectively. The incidence, location,morphology of intracranial artery fenestration, and other vascular anomalies were analyzed. Results (1) In 653 patients,39 (5. 97%) with 41 artery fenestrations were detected. The detection rates of basilar artery fenestration was 3. 37% (n=22),vertebral artery fenestration was 0. 31% (n=2),anterior cerebral artery fenestration was 1. 22% (n =8),anterior communicating artery fenestration was 0. 61%(n=4),and middle cerebral artery fenestration was 0. 76% (n=5),respectively. The post-circulation fenestration was mainly convex lens type (66. 67%,n =17),the anterior-circulation fenestration was mainly fissure type (76. 47%,n=24),and there was significant difference (χ2=7. 411,P<0. 05). (2) In the 39 patients,22 complicated other vascular anomalies. Most of them were unilateral or bilateral fetal-type posterior cerebral arteries (n=10),and followed by aneurysms (n=5). The locations of 5 aneurysms were far from the fenestration,3 located in the communicating segment of internal carotid artery,1 in the top of basilar artery,and 1 in the M2 segment of bilateral middle cerebral arteries. Conclusion CTA can intuitively and clearly reveal the intracranial artery fenestration and other vascular anomalies. But there is no significant correlation between arterial fenestration and vascular anomalies.

Objective To evaluate the practical value of procaleitonin(PCT)in diagnosis of pneumonia in patients after kidney transplantation.Method A total of 102 patients with pneumonia after kidney transplantation were reviewed.According to the diagnostic criteria of pathogens of pneumonia,32 patients were enrolled in bacterial group and 70 patients in non-bacterial group.The data of the PCT level and the C-reactive protein (CRP) level of the two groups were determined and compared with each other.Results There was significant difference in PCT level between bacterial pneumonia patients after kidney transplantation and non-bacterial pneumonia patients group (P<0.01).The difference in CRP level between bacterial pneumonia patients after kidney transplantation and non-bacterial pneumonia patients group was not significant (P>0.05).The changes of PCT level and the CRP level in 32 patients with bacterial pneumonia after kidney transplantation were not significant (P>0.05),and they were not associated with each other.Conclusions Monitoring the PCT level in patients with bacterial pneumonia after kidney transplantation would have an obviously clinical significance in diagnostic value.

Objective To observe the effect of interventional therapy of urokinase on sudden hearing loss.Methods65 patients with sudden hearing loss were divided into the treatment group (n=35) and control group (n=30). The patients of the treatment group were treated with urokinase pouring into vertebral artery accordingly into labyrinthine artery in order to improve internal ear microcirculation. Those of the control group were treated with routine drug dropping in vein. All patients of two groups were examined by pure tone test before and after treatment and the therapeutic effect of two groups was compared.ResultsIn the treatment group, the audition of 21 cases recovered, 12 cases got 15～30 dB increasing, 2 cases increased <15 dB. In the control group, the audition of 10 cases recovered, 4 cases got 15～30 dB increasing, 9 cases increased <15 dB and 7 cases had no obvious improvement. There was a significant difference between effects of two groups ( P<0.05).ConclusionThe effect of urokinase on sudden hearing loss is superior to routine drug dropping in vein.

Objective To evaluate the effect of the clinical nursing path integrated with the holistic nursing on advanced schistosomiasis patients with ascites. Methods A total of 226 advanced schistosomiasis patients with ascites were randomly di?vided into a control group and an experimental group (113 cases each group). The subjects in the experimental group were nursed by the clinical nursing path integrated with the holistic nursing,while those in the control group were nursed only by the holistic nursing. Then the clinical relevant indexes of the two groups were observed,and the quality of life of the patients before and after hospital discharge was assessed. Results The improvement rate,satisfaction degree,and awareness rate of health knowledge of the patients in the experiment group were 93.8%,100%and 97.4%,respectively,which were significantly higher than those of the control group(all P<0.05). The mortality rate and the complication rate of the patients in the experimental group were 0 and 2.7%,respectively,which were significantly lower than those of the control group(both P<0.05). In addi?tion,the average hospitalization days and the hospitalization cost of the experiment group were(12.2 ± 0.7)d and(4 725.0 ± 310.1)Yuan respectively,which were less than those of the control group(both P<0.01). When 6 months after the discharge from hospital,the quality of life of the patients in the experimental group in various fields was significantly better than that of the control group(all P<0.05). Conclusions The clinical nursing pathway integrated with holistic nursing can effectively improve the improvement rate and decrease the mortality of the advanced schistosomiasis patients with ascites;meanwhile,it can short?en the hospitalization time and save the hospitalization cost. Therefore,this nursing model is suitable for popularization and ap?plication in the treatment and nursing work of the advanced schistosomiasis assistance.
