Objective To investigate the expression of Bcl-2,survivin and pancreatic cancer stem cells markers Oct-4 and ABCG2 in pancreatic cancer cells resistance to chemoradiotherapy.and explore its mechanism.Methods Concurrent ehemoradiotherapy was used to obtain pancreatic cancer cells resistant to chemoradiotherapy,the pancreatic cancer cells without chemoradiotherapy treatment were used as control.Western-blot was applied to detect the expression of Bcl-2,survivin,Oct-4,ABCG2.Results The expression of Bcl-2 was 0.7955±0.0326,0.5718±0.0212,0.6137±0.0382 and 0.8733±0.0461,respectively;the expression of survivin protein was 0.8207±0.0490,0.6973±0.0211,0.7967±0.0346 and 0.8013±0.0398,respectively;the expression of Oct-4 protein was 0.8728±0.0177,0.7861±0.0139,0.4794±0.0932 and 0.4216±0.1043,respectively;the expression of ABCG2 protein was 0.7810±0.1370,0.4957±0.1126,0.6102±0.1358 and 0.4670±0.1274,respectively.in resistant pancreatic cancer cells of SW1990,BxPC3,pc3,jf305 cell line.The corresponding values in the control group were 0.4723±0.018,0.2954±0.0103.0.3587±0.0201 and 0.2718±0.0136;0.4717±0.0274,0.3587±0.0113,0.3891±0.0147 and 0.3326±0.0124;0.6053±0.0142,0.4236±0.0086.0.2385±0.0671 and 0.1985±0.0582;0.3156±0.0582.0.2360±0.0423,0.2813±0.0512 and 0.1808±0.a0370.The expression of all the four proteins significantly increased after ehemoradiotherapy(P<0.05).Conclusions Pancreatic cancer cells resistant to chemoradiotherapy may contain cancer stem cells.

Objective To analyze the causes of hypoglycemia coma in emergency diabetes patients and its corresponding nursing strategies.Methods The reasons of hypoglycemia coma was retrospectively analyzed in our hospital and the risk factors of hypoglycemic coma were analyzed by multivariate logistic regression,and the corresponding nursing strategies were summarized.Results Of the 767 critically ill patients,100 (13.04%) had hypoglycemia,among whom 27 patients (3.52%) had severe hypoglycemia.Multivariate logistic regression analysis showed that patients with type 2 diabetes history,hypoglycemic drugs therapy,hypoproteinemia,renal insufficiency,hemodialysis,malnutrition were risk factors for hypoglycemic coma.While normal hemoglobin was a protective factor for hypoglycemic coma.Conclusion Hypoglycemia is the result of multiple factors in emergency patients.Reasonable nursing measures can effectively prevent the occurrence of hypoglycemic coma in emergency patients.
