Chinese Journal of Endocrine Surgery 2016;10(3):201-205
Objective To investigate the effects of Nrf2/ARE pathway activator upregulating the expression of phase Ⅱ detoxifcation enzymes and antioxidant enzymes in islet B cell on its morphological structure in type 2 diabetic rats.Methods Type 2 diabetic rats were divided into diabetes model group (DM group),and tertiary-Butylhydroquinone intervention group(tBHQ group).At the same time,the normal control group (NC group)was set up.All rats were killed after eight-week continuous intervention.Fasting blood glucose (FBG) and fasting insulin (FINS) level were determined.Morphological structure of islet cells and apoptosis were observed.ELISA was used to determine MDA,TNF-α and T-SOD levels in serum and pancreatic tissues and Western blot was used to detect the protein expression levels of total Nrf2 and nulear Nrf2 in pancreatic tissues.Results Compared with NC group,FBG and FINS levels significantly increased and decreased in DM group respectively (all P=0.000).Compared with DM group,FBG and FINS levels significantly decreased and increased in tBHQ group respectively (all P=0.000).Compared with NC group,the number of islet cells significantly decreased and swelling,necrosis and apoptosis occurred in DM group.Islet cells in tBHQ group were significantly better than those in DM group.Compared with NC group,MDA and TNF-α levels in serum and pancreatic tissue significantly increased and TSOD levels significantly decreased in DM group (all P=0.000).Compared with DM group,MDA and TNF-α levels in serum and pancreatic tissue significantly decreased and T-SOD levels significantly increased in DM group(all P=0.000).Total Nrf2 and nulear Nrf2 in protein expression in DM group were significantly lower of than those in NC group (P()=0.000,P nulear Nrf2=0.006).Rats in tBHQ group had significantly higher protein expression of total Nrf2 and nulear Nrf2 than in DM group (all P=0.000).Conclusions Activating Nrf2/ARE pathway can reduce injury of oxidative stress and chronic inflammation on islet B cells further through upregulating the expression of phase Ⅱ detoxifying enzymes and antioxidant enzymes in islet B cells.

Objective To search for a more effective method for the treatment of traumatic tatoo. Methods According to the depth and pattern of tatoo in the skin, the ultra high frequency elecxosurgical technique was applied to make no bleeding incision. Then the particles of tatoo were exposed and removed thoroughly under a surgical microscope.Results Nine cases was treated with this method,and the degree of the particles was decreased remarkablly.Conclusion The ultra high frequeney electrosurgical technique is an ideal option in removing traumatic tatoo.

Objective To survey the current status of job stressor and exhaustion among nursing staff in the catheter room of grade Ⅲ-A general hospitals and to look for regularities.Methods 178 nursing staff coming from catheter room,operating room,and outpatient department of Shenzhou Hospital and Fengtian Hospital accepted questionnaires of Chinese Nursing Stressor Scale and Exhaustion Scale in Spring 2010.Results Chinese Nursing Stressor Scale indicated that scores of subitem and total score of job stressor in the catheter room were significantly higher than those in the outpatient department; however,there were no significant differences in scores of subitem and total score of job stressor between catheter room and operating room.On the other hand,Exhaustion Scale showed that scores of emotional exhaustion and job unconcerned feeling in the catheter room were significantly higher than those in the outpatient department,but scores of job achieved feeling in the catheter room were significantly lower than those in the outpatient department.There were no significant differences in Exhaustion Scale between catheter room and operating room nurses.Conclusions Job stressor and exhaustion were serious among nursing staff in the catheter room of grade Ⅲ-A general hospitals,which should cause the attention of management department.

Objective To observe the distributions of epidermal growth factor receptor(EGFR),transforming growth factor ?(TGF ? 1,? 2,? 3)and thyroid transcription factor 1(TTF 1)in developing lungs,and to discuss their functions and relationships each other. Methods The expression of EGFR and TGF ? was examined in mouse fetal lungs by immunohistochemistry.TIGER image analysiser was used in TTF 1 quantitative study. Results 1.In the early developmental phase,EGFR localized in the epithelium of airway surface,TTF 1 was expressed predominantly in the nuclei of distal lung buds and TGF ? was expressed in the bronchioles with localization patterns.2.At the late developmental phase,the positive reactions of EGFR and TTF 1 were mainly detected in alveolar cells.TGF ? expressed in mesenchymal at high levels.3 The average optical density(A A )of TTF 1 in the distal epithelial cells increased gradually during the development,while their volume(VOL)and volume integrated optical density(VI A )all decreased.Conclusion\ The functions of EGFR,TGF ? and TTF 1 might be respectively different at different developmental stages.They not only stimulate the process of branching morphogenesis,but also modulate epithelial maturation and differentiation.\;[

Objective To explore the correlation of the indoor carbon monoxide concentration and chronic diseases by monitoring the indoor carbon monoxide concentration timely.Methods Collected the data of non-traumatic patients(n=80)from July 201 1 to January 2014,and assigned them into the experiment group with carbon monoxide concentration measured and the control group without measured.All the subjects were further divided into one group with complaint of carbon monoxide poisoning and the other one without.For patients exposed to high concentration of carbon monoxide,carboxyhemoglobin was also measured and APACHEⅡ was scaled,and the relationship between them was analyzed.The confirmation and misdiagnosis rate of carbon monoxide poison-ing were calculated.For the patients with acute exacerbation of chronic diseases like chronic cardiac failure,chronic obstructive pul-monary disease,cerebral infarction induced by carbon monoxide poisoning,BNP,CAT and NIHSS were documented on admission and during follow-up with removal of carbon monoxide exposure and compared respectively.Results The relationship between blood carboxyhemoglobin,APACHEⅡ scores on admission and indoor carbon monoxide concentration was linear,and obviously positive.Between the experiment group(n=40)and the control group(n=40),there was significant difference(P <0.05)in confirma-tion rate and misdiagnosis rate with 80.00% vs.55.00% and 6.25% vs.81.80% respectively.For the 54 patients with carbon monoxide poisoning diagnosed,the changes between before and after removal of carbon monoxide exposure of the CAT scores of chronic obstructive pulmonary disease and NIHSS score of CI disease and myoglobin,troponin I,creatine kinase isoenzyme,BNP for chronic cardiac failure were significantly different(P <0.01).Conclusion The indoor carbon monoxide concentration may indicate the severity of carbon monoxide poi-soning,which could increase the confirmation rate of carbon monoxide poisoning,and reduce the misdiagnosis rate.It is helpful to identify carbon monoxide exposure,the common inducing factor,so as to improve the patients′clinical symptoms.

Objective To evaluate the curative effect of urokinase combined with low molecular heparin sodium in managing arteriovenous fistula embolism. Methods Toally 48 patients with arteriovenous fistula embolism treated from January 2014 to October 2015 were selected for the study, where 22 were assigned into control group and 26 as trial group according to the registration time. The former group were treated with urokinase and the latter with urokinase combined with low molecular heparin sodium. The rate of recanalization, the rate of thrombosis recurrence, and the adverse reactions were compared between the two groups. Results The recanalization rate in the trial group was higher than that in the control group (P<0.05). The rate of thrombosis recurrence in the trial group was significantly lower than that the control group. There was no statistical difference in adverse reactions between the groups. Conclusion The thrombolytic effect of urokinase combined with low molecular heparin sodium is superior to that of urokinase alone, with a higher rate of recanalization.
