OBJECTIVETo identify the genetic alteration in human keloid.
METHODSComparative genomic hybridization was applied in 6 cases of keloid to investigate the genomic imbalance (the gain or loss of genetic material).
RESULTSThe study showed that the loss of chromosome DNA copies included chromosome, 1,7,9,13,16,17,18,19,20,22. Among them, the frequently detected chromosome loss was chromosome 1 p(66.7%), 16 (83.3%), 20 (83.3%) and 22 (83.3%). The minimum overlapping regions were 1 pter-32.2,16p13.2p11.l,20q11.1-q13.2 and 16p13.2-p11.1. Frequent gain of DNA copy numbers was not found in the special regions.
CONCLUSIONSThe mapping of DNA copy variation frequency in keloid showed that there may be inhibitory genes in chromosomes 1p,16,20,22. The loss of these genes may be involved in the development and progress of keloid.

Absract: Objective To report the result of annual monitoring and analysis of nasopharyngeal virus in children with respiratory tract infections in Nanxiang, Shanghai District. Methods Nasopharyngeal secretions were collected from 4389 children with acute respiratory tract infection in outpatient department from January 2007 to September 2013, 9 common respiratory viruses were analyzed by Multiplex RT-PCR, including inlfuenza virus (FLU), parainlfuenza virus (PIV), respiratory syncytical virus (RSV) , adenovirus (ADV), human bocavirus(HBOV), human coronavirus(Cov), enterovirus(EV), human metapneumovirus(HMPV), and rhinovirus(HRV). The same analysis was done in 123 asymptomatic children during the same period. Results The positive rate of detected respiratory viruses in children with respiratory tract infections in nasopharyngeal secretions were 34.8% (1526/4389), including FLU 10.3% (453/4389), RSV 7.3% (320/4389), PIV 6.2%(274/4389), ADV 3.3%(146/4389), HBOV 2.7%(118/4389), EV 2.5%(110/4389), Cov 2.4%(105/4389), HRV 1.6%(72/4389), HMPV 1.5%(67/4389);two and more combined respiratory viral infection were found in 273 cases (6.2%). The virus detection
rate between age groups was signiifcantly different (χ2=41.91, P<0.001). The school-age group had the lowest positive rate of 23.4%and the positive rates in other three groups were all higher than 35.0%. The infant group had the higher positive rate of RSV and HRV. FLU detection rate in school-age group was 13.6%. Respiratory viruses in children with asthmatic disease has high detection rate. RSV infection rate was the highest 14.8%(30/204) in the asthmatic disease group, followed by HBOV 13.8% (28/204). In nasopharyngeal secretions of 123 asymptomatic children, virus-positive detection rate of 6.5% (8/123), which showed signiifcant difference from that in respiratory virus infection group (χ2=42.60, P<0.001). Conclusions In seven consecutive years of testing, the inlfuenza virus and respiratory syncytial virus play an important role in children with respiratory tract infections in this region. The detection rate of virus showed difference between different age groups and a higher detection rate of RSV in infants with respiratory tract infections was observed. The overall detection rate of virus was decreased with the increase of age excluding the inlfuenza virus.

OBJECTIVETo study the clinical characteristics of human bocavirus (HBoV) infection in children.
METHODSNasal and throat swab samples were collected in 843 children with lower respiratory tract infection. The multiple RT-PCR method was used to detect HBoV and six other common respiratory tract viruses. The clinical characteristics of HboV positive cases were investigated.
RESULTSAmong 843 cases, 90 were HboV positive (10.7%), 131 were respiratory syncytial virus (RSV) positive (15.5%), 117 were influenza virus positive (13.9%), 84 were parainfluenza virus positive (10.0%), 55 were rhinovirus positive (6.5%), 48 were coronavirus positive (5.7%), and 33 were human metapneumovirus positive (3.7%). Of the 90 HBoV infected patients, 45 (50%) showed a co-infection with other respiratory tract viruses. Among them, 33 were infected with one other type of virus (37%), 11 (12%) were infected with two other types of virus, and 1 case (1%) was infected with other three viruses. The HBoV positive rate in children with wheezing was significantly higher than those without wheezing (17.0% vs 9.2%; P<0.01). The common clinical manifestations of HBoV-infected patients included frequent coughing, wheezing and fever. There were no significant differences in the frequency of wheezing between HBoV and RSV infected patients.
CONCLUSIONSHBoV positive rate detected from children with wheezing is higher than from children without wheezing, suggesting that apart from RSV, HBoV is another virus causing wheezing in children with respiratory tract infection. Co-infections of HBoV with other respiratory track viruses can be present in some patients.

OBJECTIVETo study the mutation in RH120480 fragment of RUNX3 gene among the Chinese patients with keloid.
METHODS20 samples of keloids were collected with each patient's venous blood sample as normal control group. The genomic DNA was extracted from each sample. RH120480 fragment of RUNX3 gene was amplified by Polymerase Chain Reaction (PCR). The amplification products were analyzed by denaturing high-performance liquid chromatography (DHPLC). Some fragments were sequenced directly and then compared with the GenBank data.
RESULTSBy DHPLC, the results of all the blood samples showed single chromatographic peak indicating homoduplexes, meanwhile the results of keloid tissue samples showed double peak indicating heteroduplexes. Through gene sequencing, 19 cases showed gene mutation among the 20 samples of keloid. The mutation incidence was 95%. Two mutation sites were detected including base A absence in 96th sites and base C insert in 279th sites. The base A absence rate was 90% (18/20) in keloid group, and 10% (2/20) in control group. The base C insert mutation rate was 95% (19/20) in keloid group, and 0% (0/20) in control group. There was significant difference in the mutation rate between two groups on the two mutation sites.
CONCLUSIONSThere is a strong correlation between the RH120480 fragment of RUNX3 gene mutation and Keloid. RUNX3 gene could be possibly a scar suppressor gene (SSG).

OBJECTIVETo construct an off-line hybrid bioartificial liver supporting system with human liver cell line, and study it's effect on the plasma from patients with liver failure.
METHODSWe established the bioreactor using Psu-2s (Fresenius) cultured with Hep G2 cell transfected with human augmenter of liver regeneration (hALR) gene, then constructed a hybrid bioartificial liver supporting system, at last using the bioartificial liver support system to purify the plasma treated 2 hours with serum bilirubin absorbent, separated from acute on chronic liver failure patients infected by hepatitis B virus.
RESULTSBioreactor was successful constructed. The cell viability in perigastrum of bioreactor is 85.2% and cell propagated rapidly. Before and after treating with bilirubin absorbent, serum total bilirubin was (176.19 +/- 54.14) micromol/L and (50.1 +/- 16.85) micromol/L respectively (P = 0.0002). While there were no significance difference in the level of albumin, urea and glucose. At the begin and end of treatment with bioartificial liver, serum total bilirubin was (50.10 +/- 16.85) micromol/L and (30.27 +/- 15.02) micromol/L respectively (P = 0.000), the urea and albumin increased, urea has significantly difference, but the change of albumin hasn't.
CONCLUSIONThe off-line hybrid bioartificial liver supporting system with human liver cell line were builded successfully and have synthesis and metabolism functions for acute on chronic liver failure patients.

OBJECTIVEThe aim of this study was to investigate the loss of heterozygosity (LOH) on chromosome 1 pter-36.21 of keloid in order to locate the deletion areas probably harboring scar suppressor genes.
METHODSUsing polymerase chain reaction ( PCR )-denaturing polyacrylamide gel electrophoresis, 25 samples of keloid tissues and peripheral blood were analyzed.
RESULTS15 out of 25 samples of keloid tissues exhibited LOH in at least one microsatellite locus. There were deletions at more than one locus of one keloid tissue. No MSI was found. The frequency of LOH was remarkably higher in the keloid tissues (n = 25, 15, 60%) than in the normal control samples (n = 25, 1, 4%). The frequency of LOH in D1S243, D1S468, D1S507 and D1S199 was as following: (n= 25, 7, 28%), (n =25, 10, 40%), (n = 25, 13, 52%) and (n= 25, 3, 12%). The frequency of LOH in D1S243, D1S468, D1S507 were statistically significant.
CONCLUSIONThe most common LOH occurred at D1S243-D1S468-D1S507 might imply the existence of potential tumor suppressor gene of a subset of keloid , while MSI on 1 pter-36.21 may not a crucial event.
