ObjectiveTo investigate intrapulmonary expression of ICAM-1 mRNA and the relationship between the expression of ICAM-1 and lung injury in ANP. Methods ANP was reproduced by retrograde injection of 3.5% sodium taurocholate. Animals were sacrificed at 1,4,12 and 24 hours after induction of pancreatitis. Intrapulmonary ICAM-1 mRNA expression was assayed by reverse transcription-PCR. The following parameters were also measured: Serum amylase, histologic grading of lung injury and intrapulmonary myeloperoxidase (MPO). ResultsThere was intrapulmonary overexpression of the ICAM-1 mRNA on the first hour and persisted up to 12-24 hours with the increase of serum amylase and intrapulmonary MPO after pancreatitis induction. Score of the lung injury correlated well with the expression of the ICAM-1 mRNA and intrapulmonary MPO (r=0.85, 0.85 and 0.96, all P

Objective To investigate the mechanism that cause allelic dropout of amelogenin gene on X chromosome(Amel-X)when using routine Sullivan106/112 bp primer set in sex identification and discuss its influence on the forensic sex identification and the clinical diagnosis.Methods Amel-X dropout was validated with Sullivan212/218 bp and Haas-Rochholz80/83 bp primer sets.Amplification of amelogenin gene was used to analyze dropout of the Amex-X followed by sequencin.Results Sullivan212/218 bp and Hgas-Rochholz80/83 bp primer sets could be used to identify gender correctly.Three types of point mntation were observed in the forward primer binding region of the Sullivan106/112 bp primer set by sequencing in the lost Amel-X,including single point mutation at 2nd and 13th sites,respectively,and heterozygous multiple point mutations at 2nd and 13th sites.Conclusions Point mutation in the primer binding region may result in a failure to amplify amelogenin allele and thus lead to a null allele.This finding should be mid attention to because it may interfere with the sex identification.

Objective To investigate the longitudinal systolic ventricular function of children with single ventricle, and to appraise the feasibility and clinical value of velocity vector imaging (VVI) on assessing it. Methods The study group consisted of 30 patients with functional single ventricle. The control group consisted of 30 age- and gender-matched normal children. Using Sequoia C512 echocardiography machine,the peak velocity(V),peak displacement(D) ,strain(S) ,and strain rate(SR) were measured. Results Basel and median velocities,as well as basel and median displacements of rudimentary chamber side(RCS), were lower than those of septum[Basel velocity (1. 93 ± 0. 71)cm/s vs (3. 53 ± 1. 07)cm/s;Median velocity (1.19±0. 57)cm/s vs (2. 03 ± 0. 90) cm/s; Basel displacement (2. 53 ± 1.65) mm vs (6.21 ± 2. 12)mm;Median displacement(1. 26 ± 1. 06)mm vs (3. 21 ± 1.37)mm]. The values of strain of all the six segments of single ventricle were significantly lower than Corresponding segments of the control group [ basel nonrudimentary chamber side(NRCS) ( - 16. 17 ± 4. 37) % vs ( - 19. 66 ± 3. 47) % ; Median NRCS ( - 15. 23 +4.36)% vs (-19.64± 4. 75)%; Apical NRCS (-13.84 ± 5.79)% vs ( - 16. 7 ± 4. 15)%; Basel RCS(-10. 54±5.35)% vs (-19.49±3. 74)%;Median RCS ( - 10. 16 ± 5. 26)% vs ( -20. 83 ± 3. 82)% ;Apical RCS ( - 10. 97 ± 5. 22) % vs C - 18. 11 ± 4.43) %]. Aside from basel strain rates of NRCS, strain rates of all the other five segments of single ventricle were significantly lower than Corresponding segments of the control group [Median NRCS ( - 1. 21 ± 0. 42)s-1 vs (- 1.49 ± 0. 24)s-1 ;Apical NRCS ( - 1.10 ±0.41)s-1 vs (-1.47 ± 0.24)s-1;Basel RCS ( - 1.07 ± 0. 35) s-1 vs (- 1. 49 ± 0. 22) s-1; Median RCS (-0.97± 0.34)s-1 vs ( -1.48 ± 0. 20)s-1 (Apical RCS ( - 0. 93 ± 0. 39)s-1 vs ( - 1. 48 ± 0. 22)s-1]. Conclusions Longitudinal systolic ventricular function is impaired in children with functionally single ventricle. VVI can be used to asses ventricular systolic performance in children with functionally single ventricular.

Objective To explore effects of parents exposure to TBT on blood routine of F1 generation mice. Methods 80 mice including 40 males and 40 females, were randomly divided into control groups (CK) , low dose groups (LTBT), middle dose groups (MTBT) and high dose groups (HTBT).They were given dose of TBT (0,0.2,2, 20μg/kg) every day.The experiment lasted 45 days.At 60 days, one female and one male of the same concentration were bred in the same cage according to 1∶1.At postnatal day 60, blood was collected for the determination of blood routine. Results Compared with control group, the number of red blood cells and hemoglobin of F1 generation male mice in LTBT and HTBT groups were significantly increased (P <0.01); Red blood cell volume, mean corpuscular hemoglobin (P <0.01), and the lymphocyte absolute value in F1 generation male LTBT were significantly reduced (P <0.05); HTBT of female mice were significantly increased about the number of red blood cells (P <0.01).A dose-dependent increase of the hemoglobin, red blood cells, and platelet count of F1 generation female experimental groups was observed.Conclusion Parental TBT exposure affects the F1 mice blood routine.There is the greatest influence on LTBT in F1 generation male mice and on HTBT in F1 generation female mice.

Objective To investigate the value of MR perfusion imaging in early detection of findings following arterial chemoembolization of hepatocellular carcinoma Methods Twenty eight consecutive patients with pathologically-confirmed HCC were evaluated. All patients underwent MR perfusion imaging at pre-TACE and 3 to 10 days after TACE. The negative enhancement integral (NEI) ,the time to peak(TTP) ,the maximum slope of decrease (MSD) , the signal enhance ratio (SER) were acquired from MRI software FuncTool 2. 5.36a Version. Statistical analysis using SPSS 14, least significant difference test (t test) were utilized. Results The time intensive curve of tumor was observed to descend rapidly to reach the peak at pre-TACE studies, whereas it descended slowly to reach the peak on post TACE studies. The Value of TTP and SER prior to TACE were(51.2 ± 10. 3) s, 60. 6 ± 36. 3 respectively, and post TACE (43.7 ± 12. 0)s, 41.2 ±27. 5 respectively. The values of TTP and SER post TACE were lower than those prior to TACE (P < 0. 05). The value of NEI prior to TACE was 108.7 ± 58.9, and after TACE 149. 6 ±80. 1 and there was statistically significant difference (P <0. 05). The Value of MSD post TACE were lower than those prior to TACE, but there was no statistical significance (P > 0. 05). Conclusion PWI is a very sensitive imaging technique that can be used to monitor early dynamic changes of HCC following TACE.

ObjectiveTo explore and establish pre-hospital scoring system (respiration, pulse,motor and burn, RPMB) for evaluation of coal mine gas explosion injury. MethodsAfter analysis of characteristics of blast injury caused by coal mine gas explosion, a new pre-hospital scoring system,RPMB, for evaluation of blast injury was established on the basis of pre-hospital evaluation of coal mine injuries (respiration, pulse and motor, RPM). From January 2003 to December 2009, 251 patients with blast injury caused by coal mine gas explosion were collected in this study for a retrospective study. ISS≥16 points was set as the gold standard for severe wound. All the injuries were assessed by RPMB, RMP,pre-hospital index (PHI) and trauma triage rule (TTR). The consistency and detection rate of severe wounds were compared. The sensitivity and specificity were also calculated. ResultsOf 251 patients,41 patients were evaluated as severe, with high consistency rate between AIS-ISS and RPMB (kappa =0.985). The sensitivity of RPMB, RPM, PHI and TTR was 97.6%, 26.8% , 22.0% and 17.1% respectively and the specificity of those was 88. 1 % , 97.6% , 87.6% and 95.7% respectively. ConclusionRPMB is a simple and easy scoring method, with high detection rate of severe wound and potential of clinical applications.
