Fudan University Journal of Medical Sciences 2001;28(1):13-16
Purpose To observe the effect of Anti-c-myc on the apoptosis of HL60 cells and leukemicpatients' leukocytes. Methods HL60 cells and leukemic patients, leukocytes were treated with anti-c-mycoligomer-5' d(CTT CTC GAG GCA GGA GGG)3'-complementary to the transcriptional initiation of c-mycmRNA. After 10 hours, we detected the apoptosis by several methods: DNA agarose gel electropboresis,ELISA(enzyme- linked immunosorbent assay), Flow Cytometric Analysis, and Accounting the number ofapoptotic cells after stained with Wright' s. Results The apoptosis of HL60 cells were induced by theanti-c-myc oligomer, and the induction of apoptosis was dose-dependent, i. e. more HL60 cells vereapoptotic as we treated them with higher dose of the antisense oligodeoxynucleotides. Furthermore, the antic-myc oligomer also induced the apoptosis of leukemic patients, leukocytes, but had no effect on theapoptosis of normal leukocytes. Conclusions These results imply that we can treat acute myeloidleukemia with the anti-c-myc oligomer through apoptosis-inducing, and it has good specificity. This studyprovides basis for leukemia treatment.

Objective To study the relationship between cardiovascular diseases (CVD)and 24-h peritoneal protein losses (PPL) in continuous ambulatory peritoneal dialysis (CAPD)patients. Methods One hundred and seventy-eight CAPD patients in our department were enrolled in this study. Their 24-h PPL was measured and other clinical data were recorded at the beginning. Meanwhile, Doppler ultrasound examination was performed. They were then followed-up prospectively for the development of CVD. Results The average of 24-h PPL was (5.0±1.8) g.Patients with diabetic status or preexisting CVD or carotid arteries arteriosclerosis had higher 24-h PPL than those without (t=2.082, P=0.039; t=2.601, P=0.010; t=2.217, P=0.029). 24-h PPL was positively correlated with left ventricular end-diastolic diameter (LVDd), interventricular septal thickness (IVSTd), posterior wall diameter of left ventricle at end-diastolic (LVPWd) and left ventricular mass index (LVMI) (r=0.222, P=0.040; r=0.217, P=0.043; r=0.339, P=0.002; r=0.305, P=0.007). It was negatively correlated with ejection fraction of left ventricle (r=0.221, P=0.040). One hundred and fourteen CAPD patients were prospectively followed-up for at least twelve months. Patients developing CVD were 40.4% and 19.3% for high and low PPL groups respectively (x2=6.035, P=0.014). In the multivariable logistic regression analysis, the 24-h PPL was one of the independent factors for developing CVD. Conclusions There is a significant and independent relationship between 24-h PPL and new cardiovascular events. 24-h PPL may be an important predictor of cardiovascular disease.

Objective To investigate the effect of stress-related hyperglycemia on myocardial function of patients with cardiac disorder after non-cardiac surgery.Methods The clinical data of 211 patients having undergone thoracic or abdominal operations in Department of Critical Care Medicine of Sun Yat-sen University Cancer Center were retrospectively analyzed. According to the postoperative average blood glucose level in the following 3 days after surgery and the patients' history of cardiac disorder, they were divided into four groups: without hyperglycemia (blood glucose ≤ 10 mmol/L) and cardiac disorder group (HG0CV0 group), without hyperglycemia but with cardiac disorder group (HG0CV1 group), with hyperglycemia (blood glucose > 10 mmol/L) but without cardiac disorder group (HG1CV0 group) and with hyperglycemia and cardiac disorder group (HG1CV1 group). The correlations between the blood glucose and each level of the following items: high-sensitivity cardiac troponin I (hs-cTnI), brain natriuretic peptide (BNP), myocardial zymogram aspartate aminotransferase (AST), creatine kinase (CK), MB isoenzyme of creatine kinase (CK-MB), lactic dehydrogenase (LDH), lactic dehydrogenase isoenzyme (LDH-1), myoglobin (MYO), α- hydroxybutyrate dehydrogenase (HBDH) in each group were analyzed.Results The postoperative blood glucose levels of all 211 patients were significantly higher than those before operation (mmol/L: 8.7±0.2 vs. 5.7±0.2,P < 0.05), and the blood glucose level more than 6.1 mmol/L in postoperative 179 patients accounted for 84.8% of the total. In HG0CV0 group, the postoperative blood glucose level was positively correlated with MYO and AST [r values were 0.193, 0.307; 95% confidence intervals (95%CI) were 0.010 - 0.362, 0.096 - 0.479;P values were 0.038, 0.003]. There were no correlations between postoperative blood glucose level and hs-cTnI, BNP, LDH, LDH-1, HBDH, CK and CK-MB (allP > 0.05). In HG0CV1 group, the postoperative blood glucose level was negatively correlated with hs-cTnI level (r = -0.609, 95%CI = -0.810 to -0.264,P = 0.001). There were no correlations between postoperative blood glucose level and the levels of BNP, MYO, AST, LDH, LDH-1, HBDH, CK and CK-MB (allP > 0.05). In HG1CV0 group, there were no correlations between postoperative blood glucoselevel and hs-cTnI, BNP, MYO, AST, LDH, LDH-1, HBDH, CK and CK-MB (allP > 0.05). In HG1CV1 group, the postoperative blood glucose level was positively correlated with hs-TnI level (r = 0.837, 95%CI = 0.476 - 0.984,P = 0.001). There were no correlations between postoperative blood glucose level and the levels of BNP, MYO, AST, LDH, LDH-1, HBDH, CK and CK-MB (allP > 0.05).Conclusion The early stress-related hyperglycemia after non-cardiac surgery may have a protective effect on myocardial function of patients with cardiac disorder.
