Correlation between aortic arch calcification and arteriovenous fistula failure in maintenance hemodialysis patients / 中华肾脏病杂志

Objective:To explore the relationship between aortic arch calcification (AoAC) and arteriovenous fistula (AVF) failure in maintenance hemodialysis (MHD) patients.Methods:The patients who underwent initial AVF and started MHD in the General Hospital of Ningxia Medical University from September 2016 to September 2017 were retrospectively recruited and prospectively followed up until two years after AVF surgery or withdrawal from MHD or death. Calcification of the aortic arch was estimated with plain chest radiology. The patients were divided into four groups (0-3 grade) according to the aortic arch calcification score (AoACs). Spearman correlation analysis was used to analyze the relationship between AoACs and AVF failure. Multivariate logistic regression was used to analyze the influencing factors of AVF failure.Results:A total of 165 MHD patients were included in this study, with age of (55.52±14.06) years old and 102 males (61.82%). Among 128 AoAC patients (77.6%), 45 patients were categorized as grade 1 (27.3%), 35 patients as grade 2 (21.2%) and 48 patients as grade 3 (29.1%). There was significant difference in the, age, pulse pressure, corrected calcium, phosphorus, diastolic blood pressure, intact parathyroid hormone and AVF failure between AoAC group and no AoAC group (grade 0 calcification) (all P<0.05). The results of Spearman correlation analysis showed that AoACs was positively correlated with AVF failure ( r=0.759, P=0.010), age ( r=0.407, P<0.001), pulse pressure ( r=0.575, P=0.006), and diabetes history ( r=0.848, P=0.049), blood calcium ( r=0.591, P=0.018), and blood phosphorus ( r=0.509, P=0.012), and negatively correlated with diastolic blood pressure ( r=-0.614, P=0.013). Multivariate logistic regression analysis showed that diabetes history ( OR=6.702, 95% CI 1.431-31.396, P=0.016), high corrected calcium ( OR=10.830, 95% CI 3.479-35.300, P=0.008), high phosphorus ( OR=3.792, 95% CI 1.128-12.750, P=0.031) and AoAC ( OR=4.473, 95% CI 1.490-13.428, P=0.008) were the independent influencing factors of AVF failure. Conclusions:AoAC is an independent risk factor for AVF failure in MHD patients. Evaluation of AoAC has predictive value for AVF failure.

Study on liver function and viral lood of pediatric AIDS patients with HBV/HCV co-infection receiving HAART / 中国免疫学杂志

Objective:To investigate the change of liver function,viral load and CD4+T count in pediatric AIDS patients with HBV/HCV co-infection after HARRT therapy,and explore the effect of HBV/HCV co-infection on HAART.Methods:95 pediatric AIDS patients without HBV/HCV co-infection ( group A) ,9 pediatric AIDS patients with HBV co-infection ( group B) and 23 pediatric AIDS patients with HCV co-infection ( group C) who received HAART for 2 year were enrolled.Liver function,viral load and CD4+T count were detected before and after HAART.Results:After HAART for 2 years,26 patients (20.5%) were found with liver injury of grade 2 (1000.05 ) .Conclusion: Co-infection of HBV/HCV can aggravate the liver damage of HIV-1 infected children,but has no significant effect on HAART.

The curative effect of mammotome minimally invasive biopsy system in the treatment of benign breast mass / 中国基层医药

Objective To compare the curative effect of ultrasound guided mammotome minimally invasive biopsy system and open operation in the treatment of benign breast mass .Methods 60 benign breast mass patients with total 115 phymas were selected as treatment group , and were given the mammotome minimally invasive biopsy treatment .60 benign breast mass patients with total 105 phymas who were given traditional open operation at the same time,were selected as control group .The treatment effect and satisfaction condition of patients in the two groups were compared.Results The phymas of patients in two groups were all removed by operation .The operation time,blood loss,healing time and scar size after operation in the treatment group were all shorter than those in the control group (t=2.41,3.87,2.44,9.84,P<0.05 or P<0.01).The incidence rate of postoperative complication in the treatment group (6.66%) was significantly lower than that in the control group (20.00%)(χ2 =4.62,P<0.05).The postop-erative satisfaction of patients in the treatment group (95.00%) was significantly higher than that in the control group (20.00%)(χ2 =5.26,P<0.05).Conclusion Compared with open operation ,ultrasound guided mammotome min-imally invasive biopsy system in the treatment of benign breast mass has advantages of shorter operative time ,smaller operative trauma ,shorter postoperative healing time ,less operative complication ,higher satisfaction of patients .

Value of plasma ADMA in predicting cardiac structure and function of patients with chronic kidney diseases / 中华肾脏病杂志

Objective To explore the predicting value of plasma asymmetric dimethylarginine (ADMA) in cardiac structure and function of patients with chronic kidney diseases (CKD).Methods A total of 100 CKD patients were enrolled in this cross-sectional study.According to staging of the K-DOQI guideline,CKD patients were divided into five groups.Twenty healthy people were enrolled as control.Plasma level of ADMA was determined by reversed-phase high performance liquid chromatography.Cardiac structure and function were detected by color echocardiography.Results Plasma levels (μmol/L) of ADMA in CKD stage 3 to 5 patients (1.3318±0.4684,1.5712±0.4210,2.1093±0.7714) were significantly higher than those in CKD stage 1,2 patients (0.4387±0.2575,0.4809±0.2846) and healthy control (0.4611±0.1615) (all P＜ 0.01).Meanwhile,ADMA level of CKD stage 5 was significantly higher as compared to CKD stage 3-4.The left ventricular mass index (LVMI) was significantly higher in stage 4-5 patients than that in stage 1-3 and healthy control.Plasma ADMA was positively correlated with LVMI (r=0.476,P=0.028) and negatively correlated with left ventricular ejection fraction (EF) (r=-0.327,P=0.041).Multivariate stepwise Logistic regression analysis revealed plasma ADMA level was an independent predictors for EF (OR=0.984,P＜0.01).Conclusions Plasma level of ADMA begins to increase in CKD patients of stage 3 and rises proportionally to the decline of renal function.Plasma ADMA level is useful in predicting the cardiovascular complications of CKD patients.

Different Therapeutic Regimens for Diabetic Patients with Sulfonylureas Secondary Failure:Cost-Effectiveness Analyses and Evaluation of Life Quality / 中国药房

OBJECTIVE:To compare the cost-effectiveness and quality of survival among different therapeutic regimens for diabetic patients with sulfonylureas secondary failure(SSF).METHODS:The cost-effectiveness and the effects on patients life quality of four therapeutic schemes(group A: mixed-human insulin;group B:repaglinide and metformin;group C:repaglinide and acarbose;group D:glipizide,metfonmin and novolin N) were compared using cost-effectiveness analysis in pharmacoeconomics and DSQOL(diabetic patients’ score on quality of life).RESULTS:Group A showed the best clinical efficiency,with cost-effectiveness ratio significantly lower,physiological and psychological dimension scores significantly higher and social dimension score significantly lower than in all the other 3 groups,and all were of significant differences,but no significant differences were noted in therapeutic dimension score as compared with the other 3 groups.CONCLUSION:Insulin is optimal among four schemes in the treatment of diabetic patients with sulfonylureas secondary failure in the cost-effectiveness analysis, and it has the best efficacy in the improvement of patients’ physiology and psychology.
