Objective To explore the function of ERCC2/XPD polymorphisms in the repair of DNA damage induced by UVC. Methods Plas?mids stably expressing ERCC2/XPD rs13181 AA(Lys751)and ERCC2/XPD rs13181 CC(Gln751)were transfected into Chinese hamster ovary cells,and the stable ERCC2 transfected cell lines were obtained. MTT assay was used to compare the inhibitory rates of the transfected cells treated with UVC at different irradiation intensity. The DNA damage repair ability of the transfected cells treated with UVC for 1,3,6 and 24 h was detected by modified comet assay. Results Compared with UV5ERCC2(CC),UV5ERCC2(CC) was more sensitive to UVC with decreased cell viability. DNA damage level of UV5ERCC2(CC) cells was more serious than UV5ERCC2(CC). Conclusion DNA repair capacity of ERCC2/XPD rs13181A allelic is lower than its wild?type,suggesting that ERCC2/XPDpolymorphisms play a critical role in UVC?induced DNA damage repair.

Objective To investigate the infect capability of recombinant adenovirus mediated PDGF to human umbilical cord derived mesenchymal stem cells (MSCs). Methods The PDGF cDNA sequence was amplified with RT-PCR and constructed recombinant adenovirus vector AdPDGF. The human umbilical cord derived MSCs were isolated and cultured. In vitro AdPDGF infected MSCs with various MOI,and determine the efficiency using FACS and fluorescence microscope. Trypan blue and MTT assay was used to detect cell viability and proliferation. ELISA was used to quantify PDGF secretion. Results Recombinant adenovirus AdPDGF was successfully and constructed,in which infection efficiency to MSCs was dose dependent. The highest efficiency was around 87.36 % when MOI =50,at which cell viability and proliferation wasn' t impaired. Cell viability of uninfected,AdPDGF infected and control virus infected MSCs was (97.8 ±2.3) %,(91.9±4.0) % and (92.8±4.0) %,separately. The cell proliferation was (100±16.8) %,(95.9±12.0) % and (87.5±9.7) %,separately. There was no statistic significance among AdPDGF infected,control virus infected and uninfected MSCs. 48 hrs post infection,PDGF secretion can be measured from infectious MSCs' supernatant. The secretion level was (1.53±0.37),(3.03±0.68) and (5.25±0.92) ng/ml,separately,when MOI= 10,30,50. No PDGF can be detected from MSC-GFP and control MSC group. Conclusion Recombinant adenovirus AdPDGF was constructed and can infect human umbilical cord derived MSC at high efficiency.

Objective To investigate the effect of different doses of sufentanil combined with dexmedetomidine ( DEX) on hemodynamic and Narcotrend index ( NI) during pediatric anesthesia induction. Methods A total of 45 children with lower abdominal surgery were randomly divided into three groups evenly: sufentanil 0. 1 μg·kg-1+ DEX (S1 group),sufentanil 0. 2 μg·kg-1+DEX (S2 group),and sufentanil 0. 3μg·kg-1+DEX (S3 group). Patients in each group began with intubation at the peak point of administration. Blood pressure,heart rate,perfusion index (PI) and NI were detected at the baseline (t0), delivering DEX 0.5 μg·kg-1·h-1 and sufentanil intravenously for 5 min (t1),delivering sufentanil for 3 min (t2),time of intubation ( t3 ) ,1 min ( t4 ) ,and 5 min ( t5 ) after intubation. The application rate of atropine and propofol was recorded. Patient recovery time and adverse reactions were observed. Results Compared with basicline value at t0 time point, hemodynamic parameters and NI were decreased at t1 and t2 ,while PI was increased in both groups. At t3 ,t4 ,and t5 ,all of the indicators in S1 group were significantly different from those at t0 ,and also significantly different from those in S2 and S3 group. Six patients were treated with propofol in S1 group and four presented with agitation after operation,more than S2 and S3 groups. Three patients were treatment with atropine in S3 group. Conclusion Sufentanil (0. 2 μg·kg-1 ) combined with dexmedetomidine can be used to induce intubation for pediatric anesthesia with stable hemodynamic profile and low incidence of adverse effects.
