Objective To clinically analyze the incidence of early extrapulmonary complications in premature infants with bronchopulmonary dysplasia(BPD),including periventricular intraventricular hemorrhage(PVH-IVH),white matter injury(WMI),parenteral nutrition associated cholestasis(PNAC) and metabolic bone disease(MBD),in order to direct the prevention and monitoring of these complications in BPD patients.Methods The clinical data of premature infants who were admitted to the neonatal department between September 2014 and December 2015 was retrospectively analyzed.A total of 87 premature infants diagnosed with BPD were studied as BPD group,while other 90 premature infants without BPD who were hospitalized at the same time were randomly selected as non BPD group.The occurrence of several common extrapulmonary complications was compared between two groups,including PVH-IVH,WMI,PNAC and MBD.Results The incidence of PVH-IVH in BPD group increased compared with non BPD group[(26.4%(23/87) vs 11.1%(10/90)] (P＜0.01),grade Ⅰ-Ⅱ PVH-IVH was more often seen in the BPD group too[24.1%(21/87) vs.11.1%(10/90)](P＜0.05),although the difference between two groups regarding the incidence of grade Ⅲ-Ⅳ PVH-IVH was not significant (P＞0.05).The incidence of WMI in BPD group was much higher than that in non BPD group[33.3%(29/87) vs 16.7%(15/90)] (P＜0.05),especially periventricular leukomalacia,the severe type of WMI,was more often found in BPD group than that in non BPD group[13.7%(12/87) vs 2.2%(2/90)](P＜0.05).The incidences of PNAC[22.9%(20/87) vs 5.5%(5/90)],MBD[17.2%(15/87) vs 3.3%(3/90)] and MBD with imaging changes[6.9%(6/87) vs 0] were all higher in BPD group compared with non BPD group,with significant differences between the two groups (P＜0.05).Conclusion BPD patients are more likely to have early extrapulmonary complications like PVH-IVH,WMI,PNAC and MBD than other preterm infants.It is crucial to prevent these complications reasonably and monitor them regularly for the BPD patients in order to improve the quality of life.

Objective To investigate the oxidative damage of ultraviolet A (UVA) radiation to primary cultured human keratinocytes and the protective effects of sunscreens from UVA Methods The levels of malondialdehyde (MDA) in supernatant and the activities of catalase (CAT) and superoxide dismutase (SOD) in intra keratinocytes were determined among primary cultured human keratinocytes irradiated by UVA radiation at different dosages The protective effects of sunscreens from UVA radiation were evaluated also Results With the dosages of UVA radiation increasing from 2 88 J/cm 2 up to 11 52 J/cm 2,the levels of MDA increased from 2 54 ?mol/L to 6 75 ?mol/L,the activities of CAT decreased from 15 76 U/mg(prot) down to 6 33 U/mg,the activities of SOD decreased from 25 55 NU/mg(prot) to 23 81 NU/mg(prot) After the primary cultured human keratinocytes were irridiated by UVA radiation with the same dosages as mentioned above through a piece of quartz glass surface of which was smeared by the broad spectrum sunscreens,the levels of MDA increased from 2 18 ?mol/L to 4 82 ?mol/L,the activities of CAT decreased from 17 19 U/mg(prot) to 10 35 U/mg(prot),the activities of SOD decreased from 26 52 NU/mg(prot) to 24 51 NU/mg(prot) Conclusion UVA radiation could cause significant oxidative damage to human keratinocytes Under the conditions of this study,the broad spectrum sunscreens had certain protective effects on keratinocytes from UVA radiation

Objective To compare the differences of two kinds of EIA reagents for HIV-1/2 (Ab/Ag) screening results of voluntary blood donors,in addition to find out the feasibility of reducing 1 times of EIA detection.Methods To collect data of HIV 1/2 screening positive results and confirmatory test for voluntary blood donors from 2009 to 2014 in Jiaxing area,and to compare the relationship of screeing test results with that of the confirmatory test,and then to analyze the relevance between S/CO values of screening test and confirmatory test.Results Screening positive rates of domestic and imported reagents,which were 9.58/10 000 and 12.43/10 000,respectively;and the confirmatory coincidence rates were 11.84％ and 9.12％,respectively.There was no significant difference (x2 =1.11,P＞0.05).The double-reagent joint detection positive rate was 1.37/10 000,and its positive predictive value was 82.86％.Single-reagent test result compared with that of double-reagent test,which had significant differences (x2domestic =94.04,P＜0.05 and x2ximported =124.86,P＜0.05).When the S/CO value was more than 6,domestic and imported reagents positive predictive values were 93.55％ (29/31) and 87.50％ (28/32),respectively.Conclusion There is no difference between domestic and imported reagents EIA-HIV1/2.

Objective To provide anatomic data for operation of inserting the electron cochlear in young children. Methods Fourteen heads,28 sides specimens of young children of 1to-5-year old were dissected,through posterior tympanum approach,via mastoidectomy,posterior tympanoto to enter posterior tympanum.The related anatomy structures of the location of the electron cochlear inserted into the proper sites were observed and measured under surgical microscope. Results The round window was seated in superior part of the round window niche.The pyramidal eminence,tendo musculi stapedius,incudostapedial joint,base of stapes,cochleariform process,round window niche and promontorium tympani were all visible from different directions.The posterior arch of stapes was situated in the prozone of scala.Scala was situated in the posteroinferior scala vestibuli.The distance from the middle point of the anterior border of the round window niche to the inferior wall was(1.49?0.42)mm,to the posterior wall of the Scala tympani(0.90?0.31)mm,to the basal tissue(1.49?0.41)mm,to the pyramidal eminence(3.28?0.55)mm,to the lateral semicircular canal(7.41?0.90)mm,to the inferior margin of the base of stapes(3.09?0.53)mm.Conclusion It is considered that the location of the insertion should be at the middle point of anterior border of the round window niche anterior from 0.90mm to 1.49mm,deorsum from 0mm to 1.49mm.When the round window niche is not found,the location of the insertion has to be at the middle point of the inferior margin of the base of stapes deorsum 3mm.

Objective To evaluate the effect of exogenous wild type p53 (wtp53) gene on radiosensitivity of human lung adenoeareinoma cell line under hypoxia. Methods Human lung adenoeareinoma cell line A549 was transfected with adenovirus carrying recombinant exogenous wtp53. Four irradiation groups were studied : normal cell ( Group A), wtp53 transfeeted cell ( Group B ), normal cell under hypoxia (Group C) and wtp53 transfected cell under hypoxia( Group D). Ceils were irradiated with 9 MeV electron beams. Cellular survival fraction was analyzed. Multi-target single-hit model was used to plot the survival curve. D0,Dq ,oxygen enhancement ratio(OER) ,sensitizing enhancement ratio(SER) and other parameters were used to evaluate the effects of wtp53 gene on radiosensitivity of A549. The cell apoptotie rate of each group was examined by flow eytometry. Results OER was 1.75 and O. 81 before and after wtp53 transfeetion. SER was 1.77 in oxic circumstance and 3.84 under hypoxia. The cell apoptotie rate of Group A and B was lower than Group C and D(F=7.92 ,P=0.048) ,with Group A lower than B and Group C lower than D (F=82.50,P=0.001). But Group B and D were similar(t=2.04,P=0. 111). Conclusions Hypoxia can increase the radiation resistance of lung adenoeareinoma cell line .4,549. The wtp53 can promote apoptosis and improve tumor radiosensitivity,especially under hypoxia.
