Objective To investigate the expression of insulin-like growth factor Ⅱ mRNA-binding protein 3( IMP3 ) in transitional cell carcinoma of bladder( TCCB ) and its clinical significance. Methods The IMP3 expressions in 6 normal bladder tissues and 48 TCCB tissues were determined by immunohistochemistry staining, and the relationships between IMP3 expression and gender, age, pathological grading and staging were analyzed statistically. Results The positive expression rate of IMP3 was 62.5% ( 30/48 ) in bladder cancer,which were significantly higher than that in normal control ( 0/6 ) ( P < 0. 05 ). The positive rate of IMP3 expression were significantly lower in superficial TCCB ( 46. 15%, 12/22 ) or early TCCB [ Grade Ⅰ 12. 5%(1/8) ,Grade Ⅱ 60. 0% (12/20) ] than that in invasive TCCB [T2 or above,81.8% (18/22) ] or advanced TCCB [ Grade Ⅲ ,85% ( 17/20 ) ] ( Ps < 0. 05 ). Conclusion IMP3 is a promising biomarker for eraly detection and assessment of the malignancy degree in TCCB.

OBJECTIVETo explore the value of HLA-DRB1 gene in predicting the outcome of unexplained recurrent spontaneous abortion (URSA) treated with paternal lymphocyte alloimmunization therapy (PLAT) in Henan Hans.
METHODSThree hundred URSA patients were recruited. Following PLAT treatment, they were divided into two groups according to the outcome of pregnancy. Polymerase chain reaction sequence specific primer (PCR-SSP) were conducted to analyze the HLA-DRB1 gene.
RESULTSFor those who have received PLAT treatment, the frequency of HLA-DRB1*11 was significantly lower in successfully treated cases than those with abortion (0.052 vs. 0.110, P < 0.05, OR=0448), whilst the frequency of HLA-DRB1*15 was significantly greater in the former (0.207 vs. 0.100, P < 0.05, OR=2.352).
CONCLUSIONFor patients who have received PLAT treatment, those with HLA-DRB1*15 are more likely to conceive that those with HLA-DRB1*11.

Objective To observe the value of conventional ultrasound combined with ultrasonic elastography for evaluating the severity of active lesions of juvenile localized scleroderma(JLS).Methods Totally 27 JLS children with 46 active lesions were prospectively enrolled.The thickness,echo and blood flow of skin and subcutaneous tissue of JLS lesions and the paired sites were evaluated using conventional ultrasound,while the skin stiffness of all lesions and paired sites were assessed using shear wave elastography(SWE),and the strain ratio of lesions and surrounding skin were evaluated using strain elastography(SE).The thickness,echo and blood flow of skin as well as subcutaneous tissue,and the Young's modulus of skin were compared between JLS active lesions and the paired sites.The correlations of the individual sum total of each Young's modulus and the limited scleroderma activity index(LoSAI)or the limited scleroderma injury index(LoSDI)were explored.Results Compared with the paired site,no significant difference of the skin thickness was found among 46 JLS lesions(P>0.05),but JLS lesions had thinner subcutaneous tissue(P<0.05)and greater Young's moduli(all P<0.05).The strain ratio of the lesions and surrounding skin were all larger than 2.For JLS children with active lesions,the individual sum total of Young's moduli had moderate rank correlations with LoSAI(rs=0.63-0.69,all P<0.05),but there was no significant rank correlation with LoSDI(rs=0.27-0.33,P>0.05).Conclusion Compared with the paired site,JLS active lesions had thinner subcutaneous tissue and stiffer skin.The higher the lesion skin stiffness,the more severe the JLS lesion activity.

OBJECTIVE:
To analyze the genomic variation characteristics of fetal with abnormal serological screening, and to further explore the value of copy number variation (CNV) detection technology in prenatal diagnosis of fetal with abnormal serological screening.
METHODS:
7617 singleton pregnant women who underwent amniocentesis for prenatal diagnosis solely due to abnormal Down's serological screening were selected. According to the results of serological screening, the patients were divided into high risk group, borderline risk group and single abnormal multiple of median (MOM) group. CMA and CNV-Seq were used to detect the copy number variation of amniotic fluid cell genomic DNA and combined with amniotic fluid cell karyotype analysis for prenatal diagnosis. Outpatient revisit combined with telephone inquiry was used for postnatal follow-up.
RESULTS:
Among 7617 amniotic fluid samples, aneuploidy was detected in 138cases (1.81%) by CMA and CNV-Seq, 9 cases of aneuploid chimerism were detected by amniotic fluid cell karyotype analysis, and 203 cases of fetus carrying pathogenic and likely pathogenic CNV (P/LP CNV) were detected, the variant of uncertain significance (VUS) was detected in 437 cases (5.7%), the overall abnormal detection rate was 10.33%. The detection rate of aneuploidy by CMA and CNV-Seq in three group were 123 cases (2.9%), 13 cases (1.3%) and 2 cases (0.4%), respectively,and showing no significant difference (χ 2=7.469, P=0.024). The detection rate of pathogenic and likely pathogenic CNV in three group were 163cases (2.6%); 24 cases (2.6%) and 16 cases (3.3%), respectively, and showing no significant difference (χ 2=0.764, P=0.682). The CMA reported 2.9% (108/3729)P/LP CNV, and CNV-seq reported 2.4% (95/3888)P/LP CNV, both tests showed similar detective capabilities (χ 2=1.504, P=0.22).The most popular P/LP CNV in this cohort were Xp22.31 microdeletion, 16p13.11 microduplication /microdeletion, 22q11.21 microduplication /microdeletion. In fetuses with P/LP CNV CNV, 59 fetuses were terminated pregnancy, and 32 of 112 fetuses born had abnormal clinical manifestations. Non-medically necessary termination of pregnancy occurred in 11 fetuses carrying VUS CNV, 322 fetuses carrying VUS CNV were born, 4 of them presented abnormal clinical manifestations.
CONCLUSION
Compared with the traditional chromosome karyotype, CMA and CNV-Seq can improve the detection rate of pathogenic and likely pathogenic CNV. CMA and CNV-seq can be used for first tier diagnosis of pregnant women in the general population with abnormal Down's serological screening.
