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.

The fabrication system for the electrochemical microfluidic device was set up based on the pulse driving and controlling of microfluids technology.The nano silver ink and glycerol solution were jetted on the glass substrates to form the microelectrode pattern and the liquid mold pattern for the microchannel.Then the microelectrode and microchannel were obtained through a sintering process and a molding process, respectively.The electrochemical mircrofluidic device was Finally prepared through a bonding process with the microelectrode and the microchannel.The influences of the system parameters on the formation of the droplet were studied, as well as the influences of the droplets diameter and the overlap on the formation of the liquid lines.The minimal width, the thickness and the resistance of the prepared microelectrode were 45 μm, 2.2 μm and 5.2 μΩ cm, respectively.The minimal width of the microelectrode was 35 μm and the surface was smooth.The electrochemical flow detection of glucose concentration was carried out with the device, and the results showed that the glucose concentration had a high linear correlation with the response current, which could be used in the quantitative detection of glucose concentration.The fabrication of the electrochemical microfluidic device based on the pulse driving and controlling of micro fluids technology has many advantages such as simple system structure, lower cost and higher accuracy of the micro droplet and can be used in the preparation of the devices in the biochemical analysis and biosensor areas.

Objective To explore the best mode of diabetic dietary education in the nursing specialist outpatient service,which is suit for China's national situation.Methods A total of 100 diabetic patients consulting diabetes diet in the nursing specialist outpatient service were divided into observation group and control group with 50 cases each by random digits table method.The routine sermonic education mode was used in control group,while the error-correction education mode was used in observation group.The question-real-time evaluation was performed at the end of the education and a follow-up evaluation after 6 months of intervention was evaluated.Results Grasp of the knowledge of diabetes diet in observation group immediately after education and 6 months after education were better than those in control group,t=3.07,3.06,P＜0.01.In the follow-up evaluation after 6 months of intervention,fasting blood glucose and glycosylated hemoglobin were (6.84±0.79) mmol/L,(6.83±0.36) ％ in observation group and (7.56±0.93) mmol/L,(7.67±0.87) ％ in control group.The indices in observation group were significantly better than those in control group,t=-4.17,-6.32,P＜0.01.Conclusions Using the error-correction education mode can correct the false dietary behavior of patients and improve the effect of the diabetic dietary education more effectively.

Objective To evaluate the role of the sodium removal and explore the relationship of sodium balance and blood pressure in patients with traditional hemodialysis.Methods Fourteen patients with maintenance hemodialysis were randomly enrolled in this study.Serum sodium concentration was measured at the pre-dialysis and post-dialysis.At the beginning of dialysis and every half hour,20 ml waste dialysates were collected,10 ml were drown from total 180 ml waste dialysates that had being mingled for measuring total NaCl removal and the removal caused by ultrafiltration.The Fisher's Exact Test was used to analyze the difference in incidence of hypertension(≥ 150/90 mmHg group or ＜ 150/90 mmHg) between the different NaCl removal groups.Results The total NaCl removal in single hemodialysis session was (29 ±14.9)g,A average of (18 ± 6.9)g sodium was removed by ultrafiltation (83 ± 58.6)％.The patients whose sodium removal in a hemodialysis session were less than 29 g,which were vulnerable to hypertension (≥ 150/90 mmHg group) (P =0.023).Conclusions The factors that effected sodium removal in hemodialysis session were complicated; most of sodium was removed by ultrafiltration of plasma water.These results demonstrated that adequate ultrafiltration volume in triple times a week rather than restriction of fluid intake was the principal factor that controls blood pressure in patients with traditional hemodialysis.

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.

Objective To analyze the value of dynamic contrast-enhanced MRI(DCE-MRI) parameters of Extended Tofts and Exchange model in the differential diagnosis of hepatocellular carcinoma (HCC) and hepatic metastases of colorectal cancer. Methods A retrospective analysis of 40 pathologically confirmed cases was conducted , including 25 cases of HCC and 15 cases of hepatic metastases of colorectal
cancer,all patients underwent DCE-MRI. Applying liver double blood supplement model , and respectively using Extended Tofts two-compartment model and Exchange model liver microvascular permeability parameters [volume transfer constant of the contrast agent(Ktrans), efflux rate from extracellular extravascular space to plasma(Kep), extravascular extracellular volume fraction(Ve)and blood plasma space volume fraction (Vp)] and the perfusion parameter hepatic arterial perfusion index(HPI) in the lesion parenchyma of HCC and metastases were calculated. We used t test to compare the differences of the parameters measured from the two types of tumors , statistically significant parameters between HCC and metastases were screened which compared with the gold standard of pathological findings in order to draw the ROC curves to evaluate the diagnostic efficacy of different model parameters, using χ2 test compared the diagnostic accuracy of optimal parameters between the two models. Results By using Extended Tofts and Exchange model , Ktrans value of HCC were (0.661 ± 0.402)/min and (0.604 ± 0.316)/min respectively, Ktrans value of hepatic metastases were (0.196±0.175)/min and (0.179±0.135)/min respectively;Vp value of HCC were (0.334±0.217) and (0.294± 0.098), Vp value of hepatic metastases were (0.089 ± 0.015) and (0.089 ± 0.022),respectively; HPI value of HCC were (0.680±0.281) and (0.769±0.245) , HPI value of hepatic metastases were (0.326±0.216), (0.373± 0.298), respectively. There were significant differences between HCC and hepatic metastases in Ktrans, Vp and HPI values in both models(P<0.05). There was not statistically significant difference between HCC and hepatic metastases in Kep, Ve values(P>0.05).Drawn ROC curves of Ktrans, Vp, HPI , the Ktrans value (area under the curve of 0.869) among Extended Tofts model parameters was selected as optimal parameter to identify HCC and hepatic metastases; the HPI value (area under the curve of 0.845) among Exchange model parameters was selected as optimal parameter to differentiate these two types of tumors.The diagnostic accordance rate of Extended Tofts model and Exchange model were 80.0%(32/40), 82.5%(33/40), respectively ; There was no significant difference between them(χ2=0.082,P=0.775). Conclusions Parameters including Ktrans, Vp, HPI of the Extended Tofts model and Exchange model in DCE-MRI perfusion can be used to identify HCC and hepatic metastases of colorectal cancer. Among these parameters, Ktrans of Extended Tofts model and HPI of Exchange model have higher diagnostic value in differentiating HCC and hepatic metastases of colorectal cancer.
