ABSTRACT
Objective:To investigate the correlation between plasma concentration and effective dose of tacrolimus in the treatment of membranous nephropathy. Methods: Totally 41 patients with membranous nephropathy were given tacrolimus combined with hor-mone at low dose. The valley plasma concentration of tacrolimus was detected using a homogeneous enzyme multiplied immunoassay method. According to the changes of 24-hour urine protein,serum albumin and kidney function, the clinical efficacy was evaluated. The correlation between curative effect and plasma concentration and dosage of tacrolimus in the treatment of membranous nephropathy was analyzed. Results:The plasma concentration of tacrolimus was (7. 47 ± 2. 74) ng·ml-1 and the dosage of administration was (0.047 ±0.007)mg·kg-1·d-1 in complete remission group, that in partial remission group respectively was (5.72 ±1.19)ng· ml-1 and(0.049 ±0.008)mg·kg-1·d-1, and that in non-remission group was respectively (3.30 ±1.08 )ng·ml-1 and (0.052 ± 0. 01)mg·kg-1·d-1. Conclusion: The clinical efficacy of tacrolimus in the treatment of membranous nephropathy has close rela-tionship with the plasma concentration,and that is promising when the plasma concentration within the range of (5. 10-9. 32) ng· ml-1 . The plasma concentration of tacrolimus isn't increased with the dosage increase in some patients.
ABSTRACT
Objective To study the time the liver injuries appeared,the different level of liver injury induced by injecting Cisplatin and Carboplatin in mice and the possible mechanisms of the liver injury.Methods Mice were intravenously given,Cisplatin(17 mg/kg),Carboplatin(67 mg/kg) respectively.In the 3th,7th,11 th and 14th day after injecting the medicines,the serum biochemistry parameters,oxidation and antioxidation parameters of liver and histopathologic change in hepatic tissue were observed.Results HE stain showed that fatty degeneration of hepatocyte in the two experiment groups in the 3th day after injecting medicines,and hepatocellular spotty necrosis,and infiltration of inflammatory cells arroud the necrotic liver were found in,Cisplatin group.The level of aspartate aminotransferase and alkaline phosphatase in the two experiment groups increased significantly compared with those in the control (group P＜0.01),and alanine aminotransferase in Cisplatin group increased significantly(P＜0.01),compared with that in the control group and Carboplatin group.Conclusion Hepatic injury was observed in the 3th day after injecting medicines,the level of liver injury in Cisplatin group was heavier than that in Carboplatin group.
ABSTRACT
OBJECTIVE:To prepare Xiaocuo emulsion and to study its stability.METHODS:The formula and techniques were optimized with metronidazuo,cimetidine,chloramphenicol and salicylic acid as the chief ingredients,and with the uniformity of emulsion as the indicator.The stability test was performed using storage test and accelerated centrifugal test.RESULTS:The optimized formula was the following,5ml azone,4ml tween-80,1g metronidazole,2g cimetidine,2g chloramphenicol,1g salicylic acid and 100ml deionized water.CONCLUSION:The preparation is reasonable in formula,simple in preparative techniques,stable in quality and feasible in production.

ABSTRACT
Objective To explore the prognosis and etiological treatment of cardiogenic syncope in children.Methods The cause,clinical manifestation,treatment and prognosis of 45 children with syncope were made in affiliated hospital of Qingdao medical university were su mmarized and analyzed.They were divided into arhythmia group and other groups,the former included myocarditis,dilated cardiomyopathy,and post-operation of congenital heart disease and the latter included tetralogy of fallot,pulmonary stenosis,hypertrophic cardiomyopathy,pericarclial effusion,and right atrial myxoma.Results There were 29 cases(64.44%) with arrhythmia in this group,of which there were 18 cases with complete atrioventricular block(CAVB),2 cases with second degree type Ⅱ atrioventricular block,3 cases with ventricular tachycardia,2 cases with bradycardia,2 cases with atrial flutter,1 case with supraventricular tachycardia,and 1 case with nonconducting atrial premature.There were 16 cases(35.56%) with other etiologies,of which there 8 cases with tetralogy of Fallot,2 cases with pulmonary stenosis,hypertrop-hic cardiomyopathy,pericardial effusion,and right atrial myxoma,respectively.Children with CAVB,bradycardia,or ventricular tachycardia resulted from viral myocarditis were given anti-virus medicine,protecting myocardium,neoepinephrine,and intravenous vitamin C 100-200 mg/(kg?d).Dexamethasone 1-2 mg/(kg?d) was given in earlier period for short course,and some children were given human ?-globulin.Eight cases were placed temporary pacemaker because of unsatisfactory therapeutic efficacy,and 1 case was placed permanent pacemaker.In all,38 cases(84.44%)were cured,1 case(2.22%)was improved,and 4 cases(8.88%) died.Conclusions Cardiogenic syncope is pediatric emergency and shall be treated immediately.Temporary pacemaker shall be placed at the right moment.
