The traditional medical treasures of zhouyi and qianjin have much in common in the aspects of logic approach,recognition characteristics,values conception,theory construction,and category system,which demonstrate that the two doctrines are closely related both geographically and historically. Bearing the same cultural genes and value orientation,sharing similar constructions of logic approaches and recognition characteristics,the two doctrines contain a great deal of wisdom in recognition and practice.

Objective To investigate the infection type,clinical features and prognosis in the infections complication patients with severe hepatitis.Methods 72 severe hepatitis patients with infections complication were analyzed retrospectively.Results The infection occurrence rate was 62.5% in the 72 severe hepatitis patients.Mortality rate was 75.56% in the patients with infections complication,and it was significantly higher than those without infections complication(29.63%).The mortality rate was 72.5% in the patients with multiple organ infections.The different bacterium infection could lead to different mortality rate,K.peneumoniae(69.89%),E.coli(58.12%),Staphylococcus aureaus(55.56%),Staphylococcus epidermidis(59.90%).The mortality rate was higher in the patients with lower sera albumin and higher serum bilirubin level.Conclusions The patients with severe hepatitis have bad outcome with infections complication.The prognosis is correlated with the dysfunction severity of liver and pathogenic bacteria.

Objective To investigate the role of TRAF2 in AP-1 signaling pathway of human B cells.Methods Human Ramos B cells were transfected with plasmids expressing YFP fusion wild type TRAF2(YFP-WT-TRAF2) or YFP fusion dominant-negative TRAF2(DN-TRAF2),or transfected with shRNA-TRAF2 and control shRNA plasmid.After incubation overnight,cells were either sorted with flowcytometry or screened by antibiotics G418.Activation of AP-1 pathway,including phosphorylation of ERK,JNK and P38,as well as nuclear translocation of AP-1 subunits were detected by western blot and ELISA.Results Overexpression of WT-TRAF2 selectively induced activition of MAPK by phosphorylation of ERK and P38,and further induced nuclear translocation of C-FOS.Moreover,both overexpression of DN-TRAF2 and transfection of shRNA-TRAF2 inhibited phosphorylation of ERK and P38,and nuclear translocation of C-FOS.Conclusion TRAF2 selectively activates some kinases in CD40 mediated AP-1 signaling pathway,and plays an important role in AP-1 activation.

Objective To observe the imaging features of branching vascular network (BVN) in polypoidal choroidal vasculopathy (PCV).Methods Eighty PCV patients (90 eyes) were enrolled in this study.The patients included 58 males and 22 females.The age was ranged from 49 to 85 years,with a mean age of 61.4 years.All the patients were examined for fundus photography,fundus fluorescein angiography (FFA),indocyanine green angiography (ICGA) and optical coherence tomography (OCT).The fibrovascular retinal pigment epithelium detachment (PED) was defined as a well-demarcated subretinal heterogeneous plaque with increasing fluorescence on FFA.The late lichenoid hyperfluorescent plaque was defined as a well-demarcated lichenoid hyperfluorescent plaque on late phase ICGA.The double-layer sign on OCT was defined as a wide range of shallow PED from Bruch membrane.Results BVN were found on early ICGA in 76 eyes among the 90 eyes (84.4％).Among these 76 eyes,18 eyes (23.7％) demonstrated the subretinal reddish-orange branches corresponding to BVN.Fifty-six eyes (73.7％) demonstrated all or part of the BVN on early FFA.Three eyes (3.9％) demonstrated branching transmitted fluorescence corresponding to BVN throughout the FFA.Seventy-three eyes (96.1％) were manifested by occult choroidal vascularization on FFA,and 21 eyes (27.6％) of them were fibrovascular PED.Among the 76 eyes with BVN,all BVN appeared earlier than polypoidal lesions on ICGA.Polypoidal lesions located on the terminal of BVN in 62 eyes (81.6％).Sixty-nine eyes (90.8％) on ICGA demonstrated the late lichenoid hyperfluorescent plaque,whose area was equal to or greater than the area of BVN shown on early ICGA.Seventy-two eyes (94.7％) had the double layer sign.Among these 72 eyes,15 eyes (20.8％) had lumen like structure within the double-layer sign.Sixty-five eyes (90.3％) had punctate and linear hyperreflectance within the double-layer sign.Two eyes (2.8％) demonstrated a hyporeflective short segment and a gap of Bruch membrane on OCT corresponding to the origin of the BVN.Sixty-three eyes (87.5％) had an area of double-layer sign that matched the area of late lichenoid hyperfluorescent plaque on ICGA.Conclusions BVN in PCV can be noted as reddish-orange branches on fundus examination.Most of the BVN are shown as early branching transmitted fluorescence but collectively an occult choroidal vascularization on FFA,as lichenoid hyperfluorescent plaque on late ICGA,and as double-layer sign on OCT whose area matches late lichenoid hyperfluorescent plaque.

Objective To investigate the application of microteaching in experimental teaching of pathophysiology. Methods A total of 120 integrated Western and Chinese medicine major students were randomly divided into experimental group (n=60) and control group (n=60). The experimental group accepted microteaching method. First, students were divided into several groups, teacher gave every group 10~15 minutes microteaching and shot the video of training process; second, students watched the video to find their deficiency with the help of teacher; and then students overcame the deficiency by repeated practice;last, the teacher gave evaluation. The control group adopted traditional method. Results The average test results of experimental group were (83.7±6.8), while the average test results of control group were ( 76 . 1 ± 7 . 2 ) , so the average test results of experimental group were higher than that of control group (P=0.000). In teaching satisfaction survey, 91.7%students were satisfied with the microteaching mode, and the satisfaction of experimental group were higher than that of control group (P=0.03). Conclusion The application of microteaching in experimental teaching of pathophysiology can improve students' experimental skills, increase students' interest in learning and improve the quality of pathophysiology teaching.
