Objective To study whether vancomycin dosage 2 g daily in Chinese adult patients would achieve the target serum trough concentration of 10-20 mg/L.Methods The data of 122 adult inpatients under therapeutic drug monitoring while receiving vancomycin were collected from September 2011 to December 2012.The correlation between vancomycin trough concentration and dosage,age,sex,body weight,concomitant medications were analyzed retrospectively.Results Vancomycin trough concentration was below the target concentration in 62.1% of the included patients.Age is an independent risk factor for attainting target concentration.Serum concentration was below target concentration in 70.0% of the patients below 60 years of age.Serum concentration was above target concentration in 62.5% of the patients above 60 years of age.Conclusions Clinicians and pharmacists should assess the dosage regimen of vancomycin cautiously,and age should be considered especially as an independent risk factor.

Objective To investigate the characteristic of lipoprotein(a)[Lp(a)]in different phases of chronic kidney disease (CKD ),to provide the basis for clinical prevention and treatment of CKD.Methods 200 patients with CKD in the Republic Hospital of Shifang were collected as study group,including 5 phases (every phase had 40 cases),and 100 healthy people were selected as control group.Measured the serum Lp(a)of both study and control group,analyzed the correlations between Lp(a)and different phase of CKD.All data were analyzed by SPSS version 17.0.The significant level was established at 0.05.Results CKD1 [(146.0 ±95.5)mg/L]and all CKD group [(231.5 ±133.2)mg/L]had higher level of serum Lp(a)than the control group [(115.5 ±70.2)mg/L] (Z=-2.800,P<0.05 and Z=-7.922,P<0.05).CKD3 had higher Lp(a)level than CKD2(Z=-2.069,P<0.05 ),while there were no significant differences between each of the other two groups.CKD4 -5 [(325 .0 ± 194.7)mg/L]also had higher Lp(a)level than CKD1 -3 [(182.0 ±110.5)mg/L](Z=-4.439,P<0.05). Conclusion Patients with CKD always have high level of serum Lp(a),which have been slowly increased since CKD1 ,meanwhile the level of Lp(a)may have a certain correlation with the stage of CKD development,since Lp(a) is an important promoting factor in the progress of CKD.
