Objective We aimed to assess effectiveness of Risk Score Scale (RSS) for aortic Dissection (AD) in early triage stage.Methods A total of 251 patients with acute chest or back pain complaints were allocated by triage nurses according to the pre-established RSS from 2011 to 2013.87 cases were assessed to have 5 points or more,and 80 cases were assessed to have 6 points or more from 95 patients diagnosed as aortic dissection (the diagnosed group) by CT angiography and magnetic resonance imaging while excluded 156 cases of control after discharge (control group).The general conditions,distribution of aortic dissection risk factors,aortic dissection risk score,sensitivity and specificity of RSS between two groups were compared.The misdiagnosis rate,missed diagnosis rate,RSS triage sensitivity and specificity and OR value were compared between RSS ≥5 points and RSS ≥6 points.Results There was significant differences in abrupt onset of severe pain intensity,ripping or tearing pain,pulse deficit or systolic blood pressure differential between extremities [upper extremity≥20 mmHg (1 mmHg=0.133 kPa) or lower extremity≥ 10 mmHg],x2 value was 62.6,94.2 and 20.2.RSS≥5 points had high sensitivity and specificity,lower missed diagnosis rate and high OR value for triage application.Conclusion RSS≥5 points could serve as a reliable evidence for early triage of aortic dissection.

Background Retinitis pigmeutosa (RP) is a progressive inheritance disease.It is characterized by highly genetical and phenotypical heterogeneity.With the rapid development of genomics,new methods are applied to the genetic screening of RP.Objective This study was to characterize the clinical features of a Chinese family with autosomal RP and to screen the candidate genes.Methods Twelve members from this family were included in the study.All participants underwent complete ophthalmologic examinations.Targeted-capture next generation sequencing (NGS) based molecular genetic analysis was performed on two patients of this RP family(Ⅱ5,Ⅱ 7).The DNA sample from the two patients was separately sequenced using custom capture gene chip,which includes 59 retinal disease genes.The sequencing results were analyzed by bioinformatics technology.Identified variations were verified in the rest family members by PCR and Sanger sequencing.This study was approved by Ethic Committee of West China Hospital,and informed consent was obtained from the subjects.Results Four members of this family were diagnosed as RP,and the rest were asymptomatic.Missense mutation (c.3065T＞C,p.Phe1022Ser) in USH2A and missense mutation (c.1699G＞A,p.Ala1319Gly) in PDE6A were found in two patients (Ⅱ 5 and Ⅱ7).The variants were not co-segregated with the phenotype of this family.The causative mutation was not found by the targeted-capture NGS based eye disease chip,but it ruled out a large number of candidate genes for RP.Conclusions Our study suggests that targeted-capture NGS based eye disease chip can quickly detect mutations in known RP genes.It can be a new applicable and efficient method for molecular genetic analysis of ocular disease.

Objective To study the effects of liver graft on the immune tolerance of intestinal allograft in auxiliary en-bloc liver-small bowel transplantation in pigs.Methods Seventy outbreed Landrace pigs were divided into 4 groups.Ten auxiliary liver-small bowel allotransplantations were performed in group A,B,C,respectively,and 5 segmental small bowel allotransplantatiom were performed in group D.Pigs were administered with routine and lower dose of cyclosporine and methylprednisolone in group B and C,respectively. No immunosuppressive agent was administered to pigs in group A and D.Results The initial time of acute rejection was obviously prolonged in group A than group D.and the acute rejection was milder in group A than group D(P＜0.05).There was no significant difference upon postoperative survival time,initial time of acute rejection and degree of acute rejection between group B and C(P＞0.05).Conclusions The immune tolerance of intestinal allograft Can be induced by liver graft in auxiliary en-bloc liver-small howel transplantation.

Objective To calculate the electric field intensity and transmembrane voltage of spherical cells and ellipsoi -dal red blood cells ( RBC) in an extremely low frequency electromagnetic field .Through this calculation , we can provide reference to the search for interaction targets and mechanics between the extremely low frequency electromagnetic field and organisms.Methods The Finite Element Method was used in the numerical computation for the spherical cell model and the ellipsoidal RBC model .Results The electric field intensity of the two types of cells on the cellular membrane was both significantly higher than the applied electric field strength , and the values of the induced field strength and transmembrane voltage varied with the direction of the electric field periodically .Conclusion The cell shape and direction of the applied electric field are not the main determinants of the cellular membrane electric field intensity and the transmembrane voltage compared with electromagnetic parameters .The distribution of the electric field intensity and transmembrane voltage are re-lated to the direction of the applied electric field.

Acute myocardial infarction (AMI) and acute massive pulmonary embolism can be characterized by no pulse electrical activity. Patients of cardiac arrest (CA) with no pulse electrical activity have a high mortality rate before the cause was corrected. Extracorporeal membrane oxygenation (ECMO), as a kind of artificial heart-lung support organ, provides treatment for CA patients. A case of massive pulmonary embolism similar to AMI was treated in the Third Central Hospital of Tianjin, who received interventional thrombolysis assisted by ECMO. Through the review of the overall development of the case, we aim to broaden the diagnosis and treatment of CA patients with no pulse electrical activity, and to improve the understanding of the complications secondary to ECMO.

To clarify the function of miR-103 in the differentiation of porcine preadipocyte, we carried out real-time PCR to detect the expression pattern of miR-103 during adipogenesis, and clarified its expression tendency through cell differentiation. Then we used adenovirus that overexpressed miR-103 to infect porcine preadipocyte. Subsequently, mRNA and protein expression of adipogenesis marker--PPARgamma and aP2 was analyzed by real-time PCR and Western blotting. At last, Oil-Red O staining was used to detect lipids accumulation in the 8th day after adipogenic inducement. The expression of miR-103 increased during adipocyte differentiation; compared with the control, the preadipocyte infected by pAd-miR-103 had an elevated expression level of adipocyte marker gene PPARgamma, aP2, and obvious lipid droplet was seen in the 8th day after adipogenic inducement. These results showed that miR-103 can enhance adipogenesis in primary cultured porcine adipocytes.

Objective To explore the effect of the cluster nursing management in the emergency endotracheal incubation .Methods One hundred and eighty patients with emergency endotracheal incubation were chosen and divided into the control group and the experimental group according the admission time , each with 90 cases.The control group received the routine nursing , and the experimental group received the cluster nursing management .The preparation time of incubation , the number of incubation , the pulse oxygen saturation ( SpO2 ) before and after the incubation and the incidence rate of complication were compared between two groups.Results Twenty-two patients including 14 cases in the experimental group and 8 cases in the control group finally changed to the other ventilation ways .The preparation time of incubation was (179.5 ±36.0) s in the experimental group, and was (317.4 ±56.0) s in the control group, and the difference was statistically significant (t=19.65,P<0.01).The success rate of one and double intubation were respectively 53.9%, 32.9%in the experimental group, and were higher than 34.1%, 21.9% in the control group, and the differences were statistically significant (χ2 =3.972,4.497, respectively; P<0.05).The SpO2 before and after the incubation were respectively (88.0 ±9.9),(85.0 ±11.3)% in the experimental group, and were (78.9 ±14.0),(72.1 ±14.4)% in the control group, and the differences were statistically significant (t=5.036,6.687, respectively;P<0.01).The differences were found in the incidences of complication including loose teeth loss and soft tissue injury bleeding between two groups (χ2 =4.378,4.304, respectively;P<0.05). Conclusions The cluster nursing management can shorten the preparation time of incubation , and increase the success rate of intubation , and prevent the reduction of SpO 2 during the intubation , and decrease the incidence of intubation complication .
