In the study, we determined the rate of appearance of micronuclei in lymphocytes of patients with malignant or benign gastric disorders as well as healthy subjects. The values are 3.40?0.26% for healthy subjects, 9.85?0.75% for gastric carcinoma, 5.62?0.33% for atrophic gastritis, and 4.86?0.23% for superficial gastritis (mean?SEM). There are very significant differences between gastric carcinoma and controls(p0.05). The results suggest that the rate reflects the degree of mutation and damage of chromosomes. The number of micronuclei increases with the degree of malignancy of carcinoma, suggesting that the determination of micronuclei may have a prognostic value and predictive of a relapse of carcinoma. The authors suggest that this method may be used as a tool in mass screening of gastric cancers.

Objective To investigate effects of Livin antisense oligodeoxynucleotides(ASODN) on the proliferation and apoptosis of human leukemia(HL60) cells.Methods Livin protein on HL60 cells was examined by immunohistochemistry.Specific phosphorothioate antisense oligodeoxynucleotides and missense oligodeoxynucleotides target Livin mRNA were synthesized and transfected into HL60 cells following cationic liposome.The proliferation inhibition of HL60 cells was assessed by MTT.The expression of Livin mRNA was detected by RT-PCR.Transmission electron microscope and TUNEL technology were used to detect the apoptosis and morphologic change.ResultsASODN of 600 nmol/L inhibited the HL60 cell proliferation and the expressions of Livin mRNA.The percentage of apoptosis detected by TUNEL was 38.48%?4.37%.cellar ultrastructure was markedly destroyed by Livin ASODN.A significant difference was found when compared with the control group(P

QT dispersion(QTd,equals maximal minus minimal QT interval on a standard ECG) has been shown to reflect inhomogeneity of myocardial repolarization and cardial electrical instability, hence,been proposed to be associated with ventricular arrhythmias.But the intrinsical mechanism of QTd is incompletely understood. Contributing to QTd are differences of action potential duration(APD) in the three-dimensional structure of ventricular myocardium, which is identified to own three cell subtypes:endocardial, midmyocardial(M cells) and epicardial cells.And findings suggest that regional differences in the duration of the M cell action potential may lead transmural and spatial dispersion of repolarization. Autonomic nerves by combining receptors on the myocardial cells,especially M cells affect significantly the APD.Concordance between heterogeneity of ventricular myocardium and heterogeneity of autonomic innervation in heart provide support for the role of autonomic nerve in the generation of the QT dispersion.

Objective:To investigate the changes and clinical significance of body mass index (BMI), blood lipid and fat soluble vitamin levels in patients with different types of severe preeclampsia.Methods:Sixty-eight pregnant women with severe preeclampsia who received antenatal examination in Lishui Maternal and Child Health Care Hospital, China from February 2017 to February 2019 were included in the study group. According to the onset time, the pregnant women were divided into an early onset group (≤ 34 weeks of gestation, n = 38) and a late onset group (> 34 weeks of gestation, n = 30). An additional 50 healthy pregnant women who concurrently received antenatal examination in the same hospital were included in the control group. Serum levels of triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), vitamin A (VA), vitamin E (VE) and vitamin D 3 (VD 3) were determined in all pregnant women. Logistic regression was used to analyze severe preeclampsia-related influential factors. Results:There were no significant differences in age, number of births and number of pregnancies among the three groups (all P > 0.05). BMI and serum levels of VA, VE, TC, TG, and LDL-C were (22.99 ± 4.39) kg/m 2, (0.48 ± 0.08) ng/mL, (11.91 ± 1.74) ng/mL, (4.93 ± 0.34) mmol/L, (1.57 ± 0.26) mmol/L, (2.68 ± 0.27) mmol/L, respectively, which were significantly higher than those in the control group [(20.68 ± 3.68) kg/m 2, (0.40 ± 0.07) ng/mL, (10.32 ± 2.56) ng/mL, (4.12 ± 0.67) mmol/L, (1.25 ± 0.32) mmol/L, (2.15 ± 0.32) mmol/L, t = 3.725, 6.698, 4.352, 8.731, 6.282, 10.512, all P < 0.05]. Serum levels of HDL-C and VD 3 in the study group were (1.51± 0.32) mmol/L and (16.16 ± 2.37) ng/mL, respectively, which were significantly lower than those in the control group [(1.88 ± 0.57) mmol/L, (17.86 ± 2.39) ng/mL, t = - 6.959, - 4.520, both P < 0.05]. BMI and serum levels of TC, TG, LDL-C, VA and VE in the early onset group were (23.13 ± 4.13) kg/m 2, (5.05 ± 0.34) mmol/L, (1.62 ± 0.27) mmol/L, (2.95 ± 0.32) mmol/L, (0.52 ± 0.06) ng/mL, (12.16 ± 1.80) ng/mL, respectively, which were significantly higher than those in the control group ( t = 6.507, 17.462, 11.217, 16.593, 9.075 and 4.142, all P < 0.05). Serum levels of HDL-C and VD 3 in the early onset group were (1.43 ± 0.28) mmol/L and (15.76 ± 2.42) ng/mL, respectively, which were significantly lower than those in the control group ( t = 14.635, 5.871, both P < 0.05). BMI and serum levels of TC, TG and VE in the late onset group were (22.70 ± 4.32) kg/m 2, (4.67±0.32) mmol/L, (1.49 ± 0.25) mmol/L and (11.45 ± 1.61) ng/mL, respectively, which were significantly higher than those in the control group ( t = 5.821, 12.857, 8.059, 3.482, all P < 0.05). Serum level of VD3 in the late onset group was (16.72 ± 2.31) ng/mL, which was significantly lower than that in the control group ( t = 4.319, P = 0.01). There were no significant differences in serum levels of LDL-C, HDL-C and VA between late onset group and control group (all P > 0.05). There were no significant differences in BMI, and serum levels of TC, TG, HDL-C, LDL-C, VA, VD 3 and VE between early onset and late onset groups (all P > 0.05). Logistic regression analysis results revealed that BMI and serum levels of TG, TC, HDL-C, LDL-C, VA, VD 3 and VE are independent influential actors of early onset severe preeclampsia ( P = 0.000, 0.008, 0.032, 0.043, 0.032, 0.002, 0.041, 0.009). BMI and serum levels of TG, TC, VD 3 and VE are independent influential actors of late onset severe preeclampsia ( P = 0.002, 0.016, 0.013, 0.031, 0.042). BMI, blood lipid and fat soluble vitamin in combination are of high value for the prediction of early onset severe preeclampsia (sensitivity 87.81% and specificity 76.67%), but they are not of high value for the prediction of late onset severe preeclampsia (sensitivity 52.51% and specificity 55.10%). Conclusion:BMI, serum lipid and fat soluble vitamin in combination are of high value in the prediction of early-onset severe preeclampsia.

: Insomnia is one of the most often complaints in the stroke patients and its incidence rate in the stroke patients is more higher than in general population.Insomnia can adversely affect the stroke patients' rehabilitation.Sedative hypnotics are still the most often used for insomnia after stroke currently.Furthermore,several studies have compared different pharmachotherapies and nonpharmachological treatments for insomnia after stroke.
