Chinese Journal of Postgraduates of Medicine 2012;35(19):17-20
Objective To detect the level of visfatin in the peripheral blood ofpafients with coronary atherosclerotic heart disease (coronary heart disease),and investigate the conelation between the level of visfatin and the lesion degree of coronary heart disease.Methods Two hundred and twenty patients who were diagnosed as coronary heart disease by coronary artery angiography from January to June 2011 (coronary heart disease group) were enrolled in this study,including 74 cases with stable angina pectoris(stable angina pectoris group),60 cases with unstable angina pectoris (unstable angina pectoris group),and 86 cases with acute myocardial infarction (myocardial infarction group).And 20 healthy persons with normal coronary artery angiography were selected as control group.The biochemical parameters of triglyceride (TG),total cholesterol (TC),high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were detected by biochemistry autoanalyzer.The level of serum visfatin was detected by ELISA analysis.The serum biochemical parameters and serum visfatin among all the groups were compared and the correlation between them was analyzed.ResuIts The level of serum visfatin of coronary heart disease group [(34.07 ±5.51) μg/L] was significantly higher than that of control group [(13.22 ±3.17) μg/L](P<0.05).TC and LDL-C of different coronary heart disease groups had no significant differences compared with that of control group (P > 0.05).TG,H DL-C and serum visfatin of stable angina pectoris group,unstable angina pectoris group and myocardial infarction group [(1.44 ±0.27) mmol/L,(1.16 ±0.12) mmol/L,(21.36 ± 3.35) μg/L; ( 1.84 ±0.32) mmol/L,(1.01 ± 0.08) mmol/L,(27.78 ±4.47) μg/L; (2.31 ±0.34)mmol/L,(0.93 ± 0.06) mmol/L,(33.14 ± 5.66) μ g/L] had statistical significance compared with those of control group [(0.93 ±0.25) mmol/L,(1.48 ± 0.24) mmol/L,(13.22 ±3.17) μg/L](P<0.05 or <0.01).TG,C,ensini score and serum visfatin of unstable angina pectoris group were significantly higher than those of stable angina pectoris group and HDL-C was obviously lower than that of stable angina pectoris group (P <0.05).Gensini score and serum visfatin of myocardial infarction group were significantly higher than those of unstable angina pectoris group and HDL-C was obviously lower than that of unstable angina pectoris group (P < 0.05).Spearman correlation analysis showed that the level of serum visfatin of coronary heart disease group was positively correlated with TG and Gensini score (P <0.05 or <0.01 ) and negatively correlatedwith HDL-C (P < 0.01 ),and had no correlation with TC and LDL-C (P > 0.05).Conclusions The highlevel expression of visfatin in the peripheral blood may be a risk factor of coronary heart disease.The changes of serum visfatin can reflect the lesion severity degree of coronary artery.

Objective To review the prevalence of nosocomial infection and the change of drug resistance in a comprehensive intensive care unit (ICU) and to provide theoretical basis for clinical prevention and treatment.Methods The strains of bacteria and fungi were isolated from ICU and their drug resistance was retrospectively analyzed from Jan.1st,2010 to Dec.31th,2011.Results The main pathogen of nosocomial infection were Gram-negative bacteria ( 73.3% ),Gram-positive bacteria ( 17.9% ) and fungi ( 8.7% ).In bacterial infection,Gram-negative and G-positive bacteria accounted for 80.3% and 19.7% respectively.In Gram-negative bacteria,pseudomonas aeruginosa was the major type (21.7%).In Gram-positive bacteria,staphylococcus aureus (31.4%) was most prominent.Drug resistance of bacteria was severe,while that of fungi was mild.Conclusion Bacteria has severe drug resistance and exhibits multi-drug resistance for commonly used antibiotics.The principle of antibiotics application should be mastered and antibiotics should be chosen according to drug-sensitivity tests.

Objective To study the influence on primipara's second stage of labor with the methods of Changqiang-pressing and Vaginal-pressing. Methods 180 primipara in the second stage of labor were randomly divided into 3 groups of 60 each, in which Changqiang-pressing, Vaginal-pressing and general guidance (the control group) were used respectively. The duration of uterine contraction and second stage of labor, vaginal bleeding amount in 2 hours after delivery, mode of delivery, perineal injury and birth case would be evaluated. Results The results in both Changqiang-pressing group and Vaginal-pressing group were statistically significant when compared with the control group, but there was no significant difference between Changqiang-pressing group and Vaginal-pressing group. Conclusions Using Changqiang-pressing and Vaginal-pressing can promote the progress of the second stage of labor for primipara, reduce the rate of cesarean section and neonatal asphyxia, and improve the quality of obstetric department.

Objective To investigate the effect of massaging Changqiang acupuncture point during the second labor course of primiparas. Methods 124 primiparas were randomized into the observation group(63 cases)and the control group (61 cases). In the observation group, after entering the second stage of labor, Changqiang point was massaged upwards by using index finger and middle finger, and at the same time primiparas were guided to hold breath to coordinate with uterine contraction to make effort to the anus point which was massaged. While the control group were directed with routine way of correctly using abdominal pressure during process of uterine contraction in the second stage of labor. Results The lasting time of uterine contraction was significantly longer in the observation group than in the control group, the time of second stage of labor was shorter, and the amount of postpartum hemorrhage in the observation group was less than those in the control group. Conclusions Application of massaging Changqiang acupuncture point could prolonge the time of uterine contraction, advance the progress of second stage of labor, and decreased the amount of postpartum hemorrhage.

Objective To investigate the effects of Livin antisense oligonucleotide (ASODN) on the proliferation and apoptosis of human leukemia (K562) cells. Methods Specific phosphorothioate ASODN and missense oligonucleotide (MSODN) target Livin mRNA were synthesized and transfected into K562 cells following cationic liposome. The proliferation inhibition of K562 cells was assessed by MTT. The apoptosis rate of each group was detected by Annexin V-FITC. The expression of Livin mRNA was detected by reverse transcription polymerase chain reaction (RT-PCR). Results ASODN at a final concentration of 600 nmol/Lcould inhibit the K562 cells proliferation (IR) was (52.99t2.67) % and the expressions of Livin mRNA (ODR)was (59.75±3.24) %, the apoptosis rate was apparently increased [(36.89±1.08) %] (P <0.01); but the difference between Lip-MSODN group, Lip control group and cell control group was not statistically significant (P >0.05).Conclusion Livin ASODN may decrease Livin gene expression, suppress K562 cells proliferation effectively, and induce significant apoptosis of K562 cells.
