ObjectiveTo investigate the significance of hearing screening combined with gene screening for neonates with high-risk of hearing impairment.MethodsNeonates admitted to the Neonatal Department of Guangdong Women and Children Hospital between July 2013 and June 2014 were enrolled in this study. They were divided into high-risk group (with high-risk for hearing impairment) (n=3 129), and control group (n=5 106). Neonate hearing screening was carried out using otoacoustic emission and automated auditory brainstem response. Blood samples were collected using a standard protocol for detecting the mutations of four common deafness genes, includingGJB2,GJB3,SLC26A4 and mitochondrial 12s rRNA.Chi-square test was used to compare the differences of the pass rate of hearing screening and positive rate of gene mutations between the two groups.ResultsThe rates of failure on otoacoustic emission, automated auditory brainstem response or both in the high-risk group were 11.92% (373/3 129), 10.32% (323/3 129) and 4.83% (151/3 129), respectively, higher than those in the control group [5.03%(257/5 106), 6.56%(335/5 106) and 2.02% (103/5 106)] (χ2=130.265, 37.354 and 51.196, allP=0.000). In the high-risk group, the overall positive rate of gene mutations was 5.63% (176/3 129), and theGJB2 andSLC26A4 gene mutation rates were 3.04% (95/3 129) and 2.40% (75/3 129)], all higher than the control group [3.15% (161/5 106), 2.04% (104/5 106) and 1.06% (54/5106)] (χ2=30.301, 8.216 and 22.517, allP<0.01). But the mitochondria 12S rRNA gene andGJB3 gene mutation rates were the same in high-risk group and control group [0.19% (6/3 129) vs 0.06% (3/5 106); 0.03% (1/3 129) vs 0.00%(0/5 106), bothP>0.05]. The rates of failure on otoacoustic emission and automated auditory brainstem response of the neonates with deafness gene mutations were 9.50% (32/337) and 10.39% (35/337), respectively, higher than the neonates without [1.14% (90/7 898) and 1.29% (102/7 898)] (χ2=154.621 and 163.399, both P=0.000).ConclusionCombined hearing screening is of clinical significance for neonates with high-risk of hearing impairment.

Objective To explore the genetic prenatal diagnosis method for acbendroplasia (ACH).Methods During May to November 2007, three ACH pedigrees were diagnosed at the Prenatal Diagnosis Center, Department of Obstetrics and Gynecology, Affiliated Drum Tower Hospital of Medical College, Nanjing University. In family 1, there was a 6-month-old male ACH infant. In family 2, the expectant mother, with 18 weeks of pregnancy, was an ACH patient. Amniocentesis was performed for prenatal diagnosis. The fetus of family 3 was diagnosed as ACH by ultrasound examination on the 39th week of gestation. Umbilical cord blood of this fetus was collected for examination. Totally, three methods, restriction enzyme (Sfc Ⅰ and Msp Ⅰ ) digestion analysis, denaturing high performance liquid chromatography (DHPLC) and sequencing analysis were performed simultaneously to detect the pathogenic mutation of flbroblastic growth factor receptor 3 (FGFR3) for the three ACH families. Results ( 1 ) The DHPLC detection: heteroduplex was detected in the patient of family 1 ; beth the patient and the fetus of family 2 showed heteroduplex results; the result of the fetus of family 3 was also heteroduplea. (2) The enzyme digestion analysis for the PCR products of 10 exon of FGFR3: after Sfc Ⅰ digestion, the PCR products of patients and the fetus of family 1 and 2 showed not only the band of 247 bp, but also bands of 162 bp and 85 bp. But their PCR products could not be digested by Msp Ⅰ , and it only showed the band of 247 bp. For the fetus of family 3, the PCR products could not be digested by Sfc Ⅰ , while after digestion by Msp Ⅰ , bands of 162 bp and 85 bp were shown up. The PCR products of the normal control could be digested by neither Sfc Ⅰ nor Msp Ⅰ. (3) The sequencing results: the heterozygote mutation of 1138 C→A was confirmed in the patient of family 1. The pregnant woman and her fetus in family 2 showed the same result. The heterozygote mutation of C→C was confirmed in the fetus of family 3. The site of 1138 was G homozygote in the normal control The three detection results of the fetus in family 2 were the same as that of the mother, which means that the fetus inherited the same pathogenic mutation from his or her mother. Conclusions Both DHPLC and restriction enzyme digestion analysis could detect the mutation of FGFR3 gene, but DHPLC is more rapid, convenient and sensitive. So DHPLC can be applied to genetic diagnosis and prenatal diagnosis for ACH patients.

Objective Up to now, there has been no sure cure for genital herpes (GH), and vaccine seems a most promis-ing approach to the prevention and treatment of herpes simplex virus Ⅱ(HSV-2) infection.In this study, we investigated the feasibili-ty of preparing a dendritic cell ( DC) vaccine modified by the adenovirus-mediated HSV-2 gD gene. Methods We subcloned the HSV-2 gD gene into the vector Shuttle-2 and constructed the recombinant adenovirus pAdeno-HSV-2 gD following identification by en-zyme digestion and DNA sequence analysis .We isolated DCs from the mouse bone marrow , analyzed their phenotypes by flow cytome-try after transfection with the recombinant adenovirus pAdeno-HSV-2 gD, and determined the expression of HSV-2 gD by immunohisto-chemistry, RT-PCR, SDS-PAGE, and Western blot. Results Based on HSV-2 DNA, the corresponding target fragments were am-plified with the gD gene primers.Agarose gel electrophoresis showed the correct size of the PCR product (1182 bp) as predicted.The recombinant adenovirus pAdeno-HSV-2 gD was obtained by transfecting the 293 cells with pAdeno-gD DNA, which had an activity of 4 ×1010 IU/mL.The contents of CD40, CD80, and CD86 were (74.2 ±3.9), (73.9 ±4.1), and (76.1 ±5.5) % in the mature DCs and (81.3 ±3.1), (80.4 ±2.9), and (83.7 ±3.9) % in the pAdeno-HSV-2 gD DCs, significantly increased as compared with those in the immature DCs ([9.7 ±0.5], [7.5 ±1.2], and [5.2 ±1.1] %) (P<0.01).No statistically significant differ-ences were found between the expression of the surface molecules in the pAdeno -HSV-2 gD DCs and that in the cytokine stimulation-in-duced mature DCs (P>0.05).RT-PCR and immunohistochemistry confirmed the expression of HSV-2 gD in DCs.SDS-PAGE and Western blot of the expressed protein showed a new band with an apparent molecular mass corresponding to the predicted size (43000). Conclusion The results of our study have paved the ground for the successful preparation and identification of a dendritic cell vaccine modified by the adenovirus-mediated HSV-2 gD gene.

Objective To evaluate the specific immune response induced by a dendritic cell-based adenovirus-mediated vaccine carrying the herpes simplex virus type 2 glycoprotein D gene (pAdeno-HSV-2 gD-DC) in BALB/c mice.Methods Forty BALB/c mice were equally divided into four groups:blank control group receiving no treatment,pAdeno-DC group immunized with pAdeno-DC,pAdeno-HSV-2 gD-DC group immunized with the previously constructed vaccine pAdeno-HSV-2 gD-DC,DC group immunized with DCs only.Totally,three rounds of vaccination were conducted at a 7-day interval.Ten days after the last vaccination,serum samples were collected and spleen cells were isolated from these mice.Enzyme-linked immunosorbent assay (ELISA) was performed to measure the level of IgG antibody against HSV-2 gD in the serum samples.Some spleen cells were stimulated with HSV-2 gD protein (10 mg/L) for 72 hours; then,ELISA was carried out to determine the levels of interferon (IFN)-γand interleukin (IL)-4 in the supernatant,and 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide (MTT) assay to estimate the proliferative activity of these cells.The cytotoxicity of spleen cells was also evaluated based on the measurement of lactate dehydrogenase (LDH) release.Results The serum level of IgG antibody against HSV-2 gD (given in the absorbance value at 450 nm) was 0.313 ± 0.034 in the pAdeno-HSV-2 gD-DC group,significantly higher than that in the pAdeno-DC group,DC group and blank control group (0.034 ± 0.009,0.028 ± 0.009 and 0.026 ± 0.010 respectively,all P ＜ 0.05).Increased proliferative activity and cytotoxicity were observed in spleen cells from the pAdeno-HSV-2 gD-DC group compared with those from the pAdeno-DC group,DC group and blank control group (cell stimulation index:1.600 ± 0.215 vs.1.063 ± 0.070,1.056 ± 0.063 and 1.020 ± 0.051,all P ＜ 0.05; percentage of cytotoxicity:37.1％ vs.16.0％,14.9％ and 15.7％,all P ＜ 0.05).The levels of IFN-γ and IL-4 (both given in the absorbance value at 450 nm) were 0.568 ± 0.031 and 0.544-± 0.043 respectively in the supernatant of spleen cells from the pAdeno-HSV-2 gD-DC group,compared to 0.266 ± 0.021 and 0.278 ± 0.037 respectively in the pAdeno-DC group (bothP＜ 0.05),0.271 ± 0.023 and 0.275 ± 0.044 respectively in the DC group (bothP＜ 0.05),and 0.252 ± 0.012 and 0.245 ± 0.051 respectively in the blank control group (both P＜ 0.05).Conclusion The vaccine pAdenoHSV-2 gD-DC could induce a specific and strong immune response in BALB/c mice.
