objective To investigate the clinical signiifcance of the changes of angiotensionⅡ(AngⅡ) in children with IgA nephropathy (IgAN). Methods Thirty children diagnosed as primary IgA nephropathy by renal biopsy (IgAN group) and 30 healthy children (control group) were recruited from May 2008 to December 2012. The serum and urine AngⅡwere measured by ELISA and compared between IgAN group and control group. The AngⅡexpression in the renal tissue of IgAN group was detected by immuno-histochemical method, and was correlated with other clinical data.. Results Urine AngⅡwas signiifcantly higher in the primary IgAN group than that of control group (P<0.05);AngⅡexpression in the urine is positively correlated with proteinuria (r=0.37, P=0.046), and is associated with the severity of clinical presentation; AngⅡexpression in kidney tissue increased with the severity of the renal histopathologic grading (r=0.69, 0.79, P=0.000), while AngⅡin blood and proteinuria, AngⅡexpression in kidney tissue were not signiifcantly correlated with the number of crescents. Conclusions Urine AngⅡin children with IgAN is signiifcantly correlated with the severity of the pathologic stage and the level of proteinuria. Urine AngⅡdetection may be useful to assess the progress and prognosis of chronic kidney disease.

OBJECTIVE:
To assess the patterns of linkage disequilibrium (LD) of 16 STR loci on X chromo- some and investigate the genetic stability.
METHODS:
Genomic DNA samples extracted from blood stains from 500 unrelated individuals and 885 lineage members from Eastern Chinese Han population were genotyped through multiplex amplification using IDtyperX-16 kit by our independent research followed by capillary electrophoresis. LD was assessed by PowerMarker v3.25 software and mutation rate of every locus was analyzed.
RESULTS:
LD were not found at the 16 X-STR loci. Allele mutations were observed at 10 loci. Among them, mutation rates of DXS6809 and DXS7132 were both up to 0.0048.
CONCLUSION
When the 16 X-STR loci included in IDtyperX-16 kit were used for parentage testing, product princi- ples can be applied to calculate the likelihood, but mutation should be taken into consideration in the case that the genotypes do not meet the genetic law (especially at DXS6809 and DXS7132).

OBJECTIVETo establish the triple-transgenic mouse model and study their biological characteristics by molecular biology, behavior and pathology.
METHODSHybrid the Tau and amyloid precursor protein (APP)/presenilins (PS1) transgenic mouse, the genotype of offspring mice were identified by PCR. Transcribed target genes were detected by RT-PCR. The protein expression of exogenous genes was detected by Western-blot. The pathological change of neurofibrillary tangles and senile plaque were observed by Bielschowsky silver staining and ABC immunohistochemical method. The changes time of learning and memory were observed by Morris water maze.
RESULTSAPP, PS1 and Tau genes were transcript in Tau/APP/PS1 mice. In 6 to 8 months old Tau/APP/PS1 mice, the neurofibrillary tangles and senile plaque could be found in cortex and hippocampus. In 6 months old Tau/APP/PS1 mice, the learning and memory abilities were worse.
CONCLUSIONWith the behavior change and pathological changes in Tau and beta-amyloid protein (AP), the Tau/APP/PS1 triple-transgenic mice can be used as a further study animal model of AD's pathogenesis and the target of drug treatment.

OBJECTIVEThe present study was performed to examine functional and structural impairment of rat sertoli cells following dibutyl phthalate (DBP) exposure.
METHODSThe 6-week-old healthy male Sprague Dawley rats were randomly divided into 4 groups with 16 animals in each group. DBP dissolved in peanut oil was administered by gavage at doses of 0, 250, 500 and 1 000 mg/kg. After 2-week DBP treatment, half of the rats were sacrificed. The rest were killed following 4-week DBP exposure. Follicle stimulating hormone (FSH) was analysed by radioimmunoassay. The relative expression levels of androgen binding protein (ABP) mRNA and inhibin (INH)alpha mRNA were determined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). The sertoli cell ultrastructures were observed by using transmission electron microscope (TEM).
RESULTSFSH levels were increased after 4-week DBP exposure with significance at doses of 250 and 1 000 mg/kg. Sperm head count and daily sperm product were decreased significantly in 500 and 1 000 mg/kg groups. The expression levels of ABP mRNA were 0.89 +/- 0.15, 0.85 +/- 0.23, 0.54 +/- 0.17, 0.52 +/- 0.16 and 0.88 +/- 0.16, 0.61 +/- 0.12, 0.48 +/- 0.15, 0.47 +/- 0.11 for 0, 250, 500 and 1 000 mg/kg after 2- and 4-week DBP treatments respectively with significance at doses of 500 and 1 000 mg/kg (P < 0.01), while the levels of INHalpha mRNA were 0.88 +/- 0.16, 0.61 +/- 0.12, 0.48 +/- 0.15, 0.47 +/- 0.11 and 0.75 +/- 0.19, 0.56 +/- 0.16, 0.53 +/- 0.08, 0.45 +/- 0.10 with significance at all exposure groups (P < 0.01 or P < 0.05). In sertoli cells of rats exposed to 1 000 mg/kg DBP, TEM photos showed more lysosomes in cytoplasm, proliferated and expanded endoplasmic reticulum and nuclei malformation.
CONCLUSIONSSertoli cell should be one of the major toxic targets. Impairment of spermatogenesis caused by DBP should be partly due to the suppression of ABP and INHalpha biosynthesis.

To study relevant risk factors of Shenmai injection induced adverse reactions by using Logistic model and ROC curve, and made the prediction for the occurrence of relevant adverse reactions/events. Case data of patients treated with Shenmai injection were collected by using the prospective, multi-center, large-sample, nested-case control method, in order to analyze the risk factors of Shenmai injection-induced adverse reactions/events, establish the logistic model and draw the receiver operating characteristic (ROC) curve for risk factors. During the study, 7632 patients (including 3 477 males and 4 155 females) were included, and eight of them suffered adverse reactions/events. Based on a multi-factor Logistic model analysis, the age (> or = 50 years) (OR = 5.061, 95% CI: 2.197-7.924; P = 0.001), the total number of medication days (OR = -1.020, 95% CI: -l.652 - 0.388; P = 0.002) and the single dose (OR = 0.245, 95% CI: 0.127-0.364; P = 0.000) were significant independent risk factors for Shenmai injection-induced adverse reactions/events. According to the results, ROC curves were drawn with age (> or = 50 years), the total number of days of inedication and single dose; The area under ROC curves the joint predictor (0.9753, 95% CI: 0.9443-1.000, P < 0.005) was larger than that of the other three single indexes, with a higher risk prediction value. The independent risk factors for Shenmai injection-induced adverse reactions/events included the age (> or = 50 years), the total number of days of medication and single dose. In clinical practice, the age (> or = 50 years), the total number of days of medication and the medication dose can be substituted in the joint predictor calculation formula (P = 1 / [1 + e(-(-21.58 + 5.061 x Xage - 1.020 x Xd + 0.245 x X(mL)] to predict the potential adverse reactions of patients and adjust the dosage regimen.

OBJECTIVETo investigate the effects of mono(2-ethylhexyl) phthalate(MEHP), the primary metabolite of di(2-ethylhexyl) phthalate (DEHP), on testosterone biosynthesis in Leydig cells cultured from the Sprague Dawley rat testis.
METHODSBased on the primary Leydig cell culture model, MEHP exposure groups involved control (0 micromol/L), 62.5, 125, 250, 500 and 1000 micromol/L. We observed mitochondria activity with the MTT method, measured the testosterone level with RIA and determined steroidogenesis acute regulatory protein (StAR) mRNA expression with RT-PCR.
RESULTSAfter Leydig cells were exposed to MEHP for 24 hours, the activity of mitochondria enhanced evidently at 250 micromol/L and then declined markedly at 1000 micromol/L compared with the control group (P < 0.01). The testosterone level showed an increasing tendency in both basal and hCG-stimulated states with statistical significance at 250 and 500 micromol/L compared with the control group (P < 0.01). However, the expression of StAR mRNA appeared unchanged at 62.5, 125 or 250 micromol/L, but exhibited a decreasing tendency at 500 and 1000 micromol/L (P < 0.01).
CONCLUSIONME- HP directly affected the activity of mitochondria and testosterone biosynthesis of the Leydig cells in vitro. StAR, the regulator of cholesterol transport into mitochondria, might not be responsible for the increase of testosterone biosynthesis induced by MEHP.
