ABSTRACT
Objective To analyze the positive features of cytomegalovirus antibodies in children aged 0-12 years in Shandong.Methods 1 429 inpatients and outpatiens w ho came to Shandong Provincial Hospital Affil-iated to Shandong University from January 2014 to December 2016 were enrolled in the study.Cytomegalovir-us IgG and IgM antibodies were detected by chemiluminescence.SPSS21.0 software was used for statistical a-nalysis.Results The positive rate of IgG and IgM antibody of cytomegalovirus was 89.36% and 16.59% re-spectively,and the positive rate of IgG antibody of cytomegalovirus in male was 88.04%,which was signifi-cantly lower than 91.32% in female (P<0.05).The positive rate of cytomegalovirus IgM antibody in male was 14.07%,which was significantly lower than 20.31% in female (P<0.05).The positive rate of IgG anti-body of cytomegalovirus was the lowest in 6-12 months age group ( 73.68%),the highest in 0-<6 months age group (92.73%);cytomegalovirus IgM antibody positive rate was the lowest in 4-12 year-old age group (10.26%),and the highest in 1-3 year-old age group (21.57%).The positive rate of IgM antibody of cyto-megalovirus was the highest in winter (22.92%) and the lowest in autumn (11.11%),and the differences of positive rate between the four seasons were statistically significant (P<0.05).A total of 4 cytomegalovirus antibody combination patterns were detected,with the most common type of cytomegalovirus IgG antibody positive and cytomegalovirus IgM antibody double negative,accounting for 73.27%.Conclusion There were differences in sex,age and season in the positive rates of CMV antibody in Shandong area.Prevention and con-trol of cytomegalovirus infection in children should be strengthened.
ABSTRACT
Objective To analyze the mortality in people aged 70 years and over who had undergone aortic valve replacement (AVR) for aortic stenosis.Methods The clinical data of 246consecutive cases aged 70 years and over,who had received AVR,were retrospectively analyzed.The 144 cases (58.5 % ) had hypertension,42 cases ( 17.1 %) had atrial fibrillation,27 cases ( 11.0 % )were obeses,and 18 cases (7.3%) had undergone previous heart surgery.Results The 29 cases (11.8%) were dead within 30 days after operation.Among them,15 cases (8.8%) were with isolated AVR and the other 14 cases (18.7%) were with an associate procedure,the difference was significant (P ＜ 0.05).The rate of postoperative complication was 24 .4%.The commoncomplications were:48 cases (19.5%) with low cardiac output,24 cases (9.8%) with renal dysfunction,52 cases (21.1% ) with prolonged ventilatory support and 12 cases (4.9%) with sepsis.In the Poisson regression analysis,the main predictors of mortality were low cardiac output,renal failure,sepsis and associate procedure.The main predictors of morbidity were CBP time ＞ 120 min,atrial fibrillation and chronic obstructive pulmonary disease.Conclusions The balance between the benefits and risks of the surgery should be well evaluated before deciding to perform AVR.
ABSTRACT
50?10~9/L in MP group was 1,10,19,19 and in control group was 0,0,2,2,respectively.The ratio of the total effi- ciency was 93.7% in the treatment group and 80.6% in control group,respectively.The clinical efficacy was dif- ferent significant between groups after 2 weeks(P0.05).Conclusion High dose MP is more effective in the patients and with obvious hemorrhagic tendency than that those of the tradition- al treatment;whereas the traditional treatment is available for other severe ITP patients.
