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.

Betulinic acids are lupine-type pentacyclic triterpenoid saponins commonly found in some plants of Betulaceae family, especially in the bark of betula alba (birch). The potent anti-HIV and anti-tumor activities of betulinic acids have been greatly concerned. The natural betulinic acids include betulinic acid, 23-hydroxy betulinic acid, betulin and so on. Some investigations on the structural modifications of betulinic acids were carried out, and many derivatives with excellent biological activity have been obtained nowadays. In this paper, the research advances of the structural modification of betulinic acids, as well as their anti-HIV and anti-tumor activities are reviewed.

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.

Objective:To investigate the relationship between gene polymorphisms of disease-relevant multiple cytokines including TNF-α,IL-6,IL-10,TGF-β1,IFN-γand acute graft versus host disease(aGVHD) in allogeneic hematopoietic stem cell trans-plantation ( allo-HSCT ) . Methods:32 cases of recipients received allo-HSCT and 36 cases of normal groups in January 2014 to December 2015 were selected as objects of study. We detected genotypes on specific SNP of target genes by polymerase chain reation ( PCR) combined with gene sequencing and observed the occurrence of aGVHD in postoperative recipients. The influence of cytokine gene polymorphisms on prognosis of allo-HSCT patients was analyzed,and the potential relationship between specific SNP mutation of the disease-relevant cytokine genes and severity of aGVHD was discussed. Results:Distribution of cytokines gene polymorphism including TNF-α-308(G/A),IL-6-174(G/C),IL-10-1082(A/G),TGF-β1+915(G/C),IFN-γ(T/A) had no significant differences with incidence of severe aGVHD(P>0. 05). However,the occurrence of severe aGVHD in allo-HSCT recipients with C/T genotype was significantly higher than C/C and T/T in SNP of TGF-β1+869(P<0. 01). Conclusion:Gene polymorphism of TGF-β1+869(C/T) in allo-HSCT patients was closely related to the occurrence of severe aGVHD. The research show allo-HSCT patients with C/T genotype occurred severe aGVHD more frequently, which is an important potential risk factor to induce the incidence of severe aGVHD. Therefore,detecting gene polymorphism of TGF-β1+869 ( C/T ) in allo-HSCT recipients and developing the appropriate therapeutic regimen may be helpful to reduce the incidence of aGVHD.

Objective To study the change of matrix metalloproteinase-2 (MMP-2) in the development of renal fibrosis and evaluate the diagnostic value of blood MMP-2 level in renal fibrosis.Methods Thirty three patients with chronic glomerulonephritis were divided into proliferation group(n=18) and fibrosis group(n=15) according to renal fibrosis degree in renal pathology.Another 8 healthy subjects were used as control group.The levels of pro-MMP-2 and MMP-2 in serum were measured with the method of SDS-PAGE enzymography.Then the levels of pro-MMP-2 and MMP-2 in serum were compared between various groups.Results The serum MMP-2 level in proliferation group was much higher than that in control group(P0.05).Conclusion There is a significant difference of serum MMP-2 between suffering group and normal control group.Therefore the detection of serum MMP-2 level can be conducive to understand the development of disease and estimate prognosis.

Objective To develop an efficient and all-round management system of personnel information based on the standards of quality management in clinical laboratory.Methods ASP.NET and database technology were used to construct a web platform and develop the management modules of personnel information.Results The developed system consisted of 4 modules.The module of onestop management for personnel archives was realized,which could be viewed and self-maintained by individuals and auto-retrieved by the system.The module of job post for staff attendance record was realized by continuous,dynamic management and permanent retrievability of registered responsibilities.The module of training and examination could publish the information for staff to complete self-training within deadline and evaluated the training effects and competence by online tests,and granted appropriate authority to staff.The module of performance assessment could evaluate the performances of staff statically and dynamically by using objective indicators and review mechanism.After the application of the system,staff archives were updated in real time instead of once for year.The time for reviewing archives of staff reduced from fifteen minutes to one minute,the error incidents of staff reduced by 20％,workload for staff training and examination reduced by 60％,and the satisfaction degree of customers for staff increased from 93％ to 96.5％.Conclusion The developed management system could realize all-round standard management with high efficiency,so it should be more effective and cost-saving than traditional manners.The staffs would be willing to accept and cooperate with it.

Objective To research the establishment and application of real-time monitoring system of temperature-humidity in clinical laboratories.Methods The collection net for temperature-humidity data was set up using wireless temperature-humidity recorders and repeaters,and a management software which connected to LIS seamlessly was developed according to the management standard for temperature-humidity in clinical laboratories and the requirements for real-time monitoring.Results The real-time monitoring system sent the collected data of temperature-humidity as needed to repeaters by wireless signal and then transferred to host computer.As long as the data was out of the allowable range,the monitoring system could trigger alarm by sending message or E-mail to administrator who accessed the host through web browser to view the status of system,save attendance records,export data and generated reports.Conclusion The automatically monitoring for temperature-humidity of circumstances and instruments in the laboratories was achieved for 24-hours of every day by the developed system and met with the relevant requirements of real-time monitoring for temperature-humidity in clinical laboratories.
