BACKGROUND:Whether determination of tacrolimus blood concentration by different immunoassay methods can influence predictive ability to immunosuppressive effects and toxicity, and whether it can be more sensitive to reflect blood concentration in patients with renal dysfunction are worthy of studying.
OBJECTIVE:To analyze the correlation of tacrolimus (FK506) concentrations determined by enzyme-multiplied immunoassay technique (EMIT) and enzyme linked immunosorbent assay (ELISA) in combination with renal function parameters.
METHODS:133 clinical blood samples were col ected. EMIT and ELISA techniques were used to determine the FK506 concentration. The correlation of two determination methods were analyzed, combined with renal function. RESULTS AND CONCLUSION:In patients with renal dysfunction, the mean results and standard deviation mensurated by ELISA were higher than those by EMIT. For blood concentration in 5-20μg/L by ELISA, the incidence of renal dysfunction occurred less than by EMIT. The overal mean results of blood concentration for two methods appeared no significant difference (r=0.904 5, P>0.05). When the concentration was less than 2.0μg/L, the concentration results by EMIT were higher than those by ELISA (P<0.01). When the concentration was more than 2.0μg/L, there was no significant difference between two determination methods (P>0.05). These findings indicate that EMIT and ELISA has good correlation, which are both suitable for clinical routine determination of plasma concentration. It is not recommended for applying EMIT method to determine low blood concentrations (<2.0μg/L). The reference range of concentration should be compartmentalized depending on combination of determination methods and renal function.

Background Medical refraction after cycloplegia is the preferable choice for precise measurement of degree of refractive error.Drugs used in China for cycloplegia include atropine and tropicamide,and the use of cyclopentolate is an alternative for ophthalmologist.However,the data for the evaluation and comparison of efficacy of the available drugs in cycloplegia is still lacking.Objective This system analysis was to evaluate the difference between atropine and cyclopentolate in cycloplegia in children.Methods A systematic literature retrieval was conducted in MEDLINE,EMbase,Google residual accommodation after cycloplegia by atropine and cyclopentolate were compared.Statistical analysis was performed using the RevMan 5.1.0 software.Results A total of 7 studies were included in this meta analysis,including 6 cohort study design and 1 randomized,doubleblinded clinical trial and 1232 eyes.For retinoscopic evaluation after cycloplegia,no significant differences were found between cyclopentolate and atropine in children with hyperopia and myopia (WMD =-0.21,95％ CI:-0.47-0.06,P=0.13 ; WMD =-0.10,95％ CI:-0.36-0.15,P =0.43).For residual accommodation after cycloplegia,no significant difference was seen between cyclopentolate and atropine in ammetropic children (WMD =0.30,95％ CI:-0.10-0.71,P =0.15).Conclusions Cyclopentolate shows the same effect on the cycloplegia as atropine in children,and it can take the place of atropine in cycloplegia in childhood.

OBJECTIVETo investigate the pathogenic infection and its drug resistance in expressed prostatic secretion (EPS) and its correlation with serum PSA, and provide some evidence for the systematic and normalized diagnosis and treatment of prostatitis.

METHODSThree EPS swabs were collected from each of the 320 prostatis patients following measurement of the serum PSA level, 1 for bacterial culture and identification, 1 for detection of Mycoplasma and drug sensitivity, and the other for examination of Chlamydia trachomatis antigen by colloidal gold immunoblot.

RESULTSTotally 244 strains were isolated from the 320 EPS samples, including 188 bacterial strains (dominated by Staphylococcus and sensitive to vancomycin or linezolid) and 44 Mycoplasma and Chlamydia strains (mainly Ureaplasma urealyticum and susceptible to josamycin or doxycycline). The serum PSA level was significantly higher in the pathogen-positive than in the pathogen-negative group ([6.98 +/- 0.56] microg/L vs [2.32 +/- 0.12] microg/L, P < 0.05).

CONCLUSIONProstatitis may lead to the elevation of the serum PSA level and the pathogens involved vary in their resistance to different antibacterial spectrums. Therefore, appropriate and individualized antibiotic therapy should be selected according to etiological diagnosis and the results of drug sensitivity test.

OBJECTIVETo investigate the influence of the rate of morphologically normal sperm (MNS) on the clinical outcomes of conventional in vitro fertilization (IVF) in patients with one retrieved oocyte.

METHODSFrom January 2013 to January 2015, a total of 256 couples with one retrieved oocyte underwent conventional IVF in our center. According to the rate of MNS, the patients were divided into two groups: MNS < 4% (134 cycles) and MNS ≥ 4% (122 cycles). We compared the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo between the two groups. A total of 75 fresh embryo transfer cycles were performed, 43 in the MNS < 4% group and the other 32 in the MNS ≥ 4% group. We also compared the rates of implantation, clinical pregnancy and abortion between the two groups.

RESULTSThere were no statistically significant differences between the two groups in the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo (P > 0.05). The rates of implantation, clinical pregnancy and abortion exhibited no remarkable differences either in the fresh embryo transfer cycles between the two groups (P > 0.05).

CONCLUSIONThe rate of MNS does not affect the clinical outcomes of conventional IVF in patients with one retrieved oocyte.
