Objective To investigate the possibility of auricle reconstruction assisted by an expander using porous silicon auricle frame.Methods An adult male with average sized,normal ears was selected.The spiral CT scan was used to acquire primitive data of his external ear.Mimics 8.1 and Geomagic studio 12 were used for 3D reconstruction and image processing.Three-dimensional model of auricle 1.4 mm in thickness was created according to the anterior auricular surface data.Finally,a metal model was made according to the 3D model of auricle.By the extrusion method,silicon auricle frame was formed from the metal model.Multiple perforations,1 mm in diameter and 1 mm internal from each other,were then made by a puncher.50 ml kidney tissue expanders were implanted between the panniculus carnosus and the fascia through an incision on the backs of 10 New Zealand white rabbits.The expander was inflated with 20 ml saline weekly,to a total of 160 ml.Maintenance of expansion lasted for a month.The expander was then removed through an incision along the expander near the back.Silicon auricle frame was inserted into the pocket.The reconstructed ears were observed for 6 months postoperation.Whether there were deformations,contractures and extrusions were observed.Results The reconstructed ears were elastic and compressible.No deformation,contracture or extrusion were observed 6 months postoperation.Scaphoid fossa,triangular fossa,helix,antihelix were legible.Conclusions The silicon frame,1.4 mm in thickness manufacted by computer aided design,could stand up to contraction of the overlying expanded flap,and it thus is possible to be used for auricle reconstruction assisted by the expander.

Objective To describe the clinical characteristics of 9 cases of idiopathic pulmonary alveolar proteinosis (iPAP) with secondary infections. Method The clinical and radiological data of 9 patients with iPAP and secondary infections admitted into Peking Union Medical College Hospital from 1 st January 1990 to 1st January 2010 were retrospectively analyzed. Results In that period, there were 97 patients of iPAP were admitted in our hospital. There were 9 patients of iPAP with secondary infections,aged (46.4±14.6)y. There were 5 males and 4 females. Among them, 6 patients were misdiagnosed as interstitial pneumonia and corticosteroids were given to them. When the infection appeared, corticosteroids were still given to 3 patients, and the other 3 patients had stopped corticosteroids for 3 to 15 and a half months. Five patients had accepted mono-lung or whole lung lavage before 1,2, 9, 14,24 months. The clinical manifestations were fever(8 cases) ,cough(9 cases) , expectoration(8 cases) ,hemoptysis(2 cases),chest pain(1 case) and moist rales(1 case). Glass-ground opacities (9 cases) and cavitations(4 case)were the main manifestations of chest radiology. Pleural effusions(1 case) was not common. The locations of infection was limited in chest:9 cases had pulmonary infection and one case was associated with pleurisy.The infectious pathogens were the acid-fast tubercle bacillus (4 cases), fungus (3 cases, candida albicans,penicillium and aspergillus fumigatus for each one) and norcardia (2 cases, one case was associated with cytomegalovirus infection). Follow-up: 6 patients were cured, 1 patient was improved and 2 patients were died. Conclusions For patients with iPAP, especially when they had been receiving corticosteroids, if they had fever and/or recently exaggerated dyspnea, especially whose chest radiology showed nodules and cavitations, the clinicians should be aware of infections diseases for them. Further specific microbiological studies and sufficient therapy should be obtained as quickly as possible.

OBJECTIVE To investigate the etiology of acute respiratory tract infection(ARI)in Hefei area and risk factors that may influence the distribution of common pathogens.METHODS Direct immunofluorescence assay was applied to detect the respiratory syncytial virus(RSV),adenovirus(ADV),influenza virus A(FluA),influenza virus B(FluB),parainfluenza virus PIV(1,2,3)and real time fluorescent quantitation polymerase chain reaction (FQ-PCR)was applied to measuring Mycoplasma pneumoniae(MP)and Chlamydia pneumoniae(CP)in nasopharyngeal secretions and sputum specimens.RESULTS Among 530 cases included in this study,421 cases (79.43%)showed positive viral etiology.ADV accounted for 73(13.77%),FluA-68(12.83%),FluB-56 (10.56%),RSV-48(9.05%),PIVl-47(8.86%),PIV3-42(7.92%),PIV2-33(6.22%),MP-32(6.03%)and CP-22(4.15%).The detected positive rate of pathogens isolated in winter was the highest(85.07%).CONCLUSIONS Acute upper respiratory tract infection(AURTI)is common and more than 75%pathogens in Hefei area are virus in which the most commonly virus is ADV.Meanwhile atypical pathogens of infection should not be ignored.

Objective To study the possible influencing factors in the formation of coronary collateral circulation in patients with chronic total occlusion (CTO). Methods Patients were enrolled having at least 1 major coronary artery angiography revealed as CTO of 144 patients. According to the Rentrop classification, patients with grade 0 and grade 1 filling were catogorized as insufficient collateral circulation group (n=72) and patients with grade 2 and grade 3 filling as collateral circulation group (n=72). Serum biomarkers and insulin-resistance by HOMA model were also studied in all patients. Results In the insufficient collateral circulation, BMI,TC,ApoB, lipoprotein a, fasting insulin HOMA-IR,HOMA- beta, CRP was significantly higher than the well collateral circulation group and ApoA-Ⅰ, ISI lower than the well collateral group ( all P ﹤0. 05 ) . Bivariate correlation alaysis showed. Rentrop score, BMI, TC, ApoB, lipoprotein a, fasting insulin, HOMA-IR,HOMA- beta and CRP are positively correlated to the formation of collateral circulation ( P ﹤ 0. 05 ); ApoA-Ⅰ and ISI were negatively correlated ( P ﹤0. 05 ) . Logistic regression analysis after calibration with weight, ApoA-Ⅰ and HOMA-beta factors, lipoprotein a ( OR 7. 575,P=0. 009), TC (OR 2. 154,P =0. 001) were found to be the independent factors of coronary collateral circulation formation. Conclusions TC, lipoprotein a, obesity, CRP, and HOMA-IR are correlated with the formation of coronary collateral circulation and may predict formation of collateral circulation in patients with CTO.

Four patients with coexistence of sarcoidosis and primary Sj(o)gren syndrome (pSS) were retrospectively analyzed.All patients were female,who were referred to our department mainly because of respiratory symptoms.Positive antinuclear antibody (ANA) was detected in 2 patients and anti-Sj(o)grens syndrome A (SSA) antibody positive in 1 patient.All patients presented specific histologic patterns of both sarcoidosis and pSS.Publications related to coexistence of these two diseases were reviewed.Forty-one patients were finally included in the analysis,among whom 37 confirmed patients were from literature search.There were 37 women and 4 men.The main clinical features presentation were xerophthalmia in 40,xerostomia in 38,hilaradenopathies in 28,interstitial lung disease in 15,respiratory symptoms in 13.The main immunologic data were positive ANA in 23,SSA antibody in 19,anti-Sj(o)grens syndrome B antibody in 10 and rheumatoid factor in 12.All patients presented specific histologic patterns of both diseases.Patients with both sarcoidosis and pSS of ten represent multisystemic involvement and positive immunologic parameters,as well as the dual expression of specific histologic characteristics.

Objective:To investigate the effect of traditional Chinese medicine (TCM) icariin (ICA) on metastatic phenotype of methotrexate (MTX)-resistant lung cancer A549 cells and elucidate the action mechanism and therapeutic value of ICA. Methods:The half inhibition concentration(IC_(50))value of ICA in inhibiting the growth of A549/MTX cells was measured by MTT assay. The colony formation rates and the morphology of cell cluster of A549/MTX and ICA-treated A549/MTX cells were determined by double-layer soft agar colony formation assay. The migration abilities of A549/MTX and ICA-treated A549/MTX cells were evaluated by cell scratch assay. The invasion ability of cells was tested by using Transwell chamber assay. Results:MTT assay showed that the IC_(50) value of non-toxic ICA plus MTX was reduced compared with that induced by equal dose of MTX (35.50±1.85 μmol/L vs 52.17±2.25 μmol/L). The colony formation rate of ICA-treated A549/MTX cells was 0.94±0.09, less than that of A549/MTX cells (1.56±1.07, P<0.05). Cell scratching assay demonstrated that the migration capability of A549/MTX cells was stronger than that of ICA-treated A549/MTX cells at 72 h (P<0.05). Transwell experiment revealed that more A549/MTX cells passed through artificial basement membrane than ICA-treated A549/MTX cells (P<0.05), indicating that the invasion capability of ICA-treated A549/MTX cells was weaker than that of A549/MTX cells.Conclusion:TCM ICA can reverse the metastatic phenotype of MTX-resistant A549 cells.

Objective To describe the clinical presentations,radiographic findings and histological pathology of bones,diagnosis,treatment options and prognosis for patients with Gorham-Stout syndrome (GSS).Methods Clinical data of 5 GSS patients seen from January 1980 to January 2008 were reviewed.Results(1)There were 2 males and 3 females,aged 15 years to 37 years(mean age was 30.2 years).(2)All of thern had osteolysis,but the site and extent of involved bones were not the same.Three cases had large amount of bloody pieural effusion and two of them had also chylous effusion.All of the 5 cases had no evidence of malignancies.Four cases accepted bone biopsy.Among them,2 cases having local puncture and open biopsy showed typical bone pathologic manifestations.(3)Various forms of treatment including bisphosphonates,calcium supplementation,active vitD3 treatment,local radiation therapy and surgical ligation of thoracic duct were tried.(4)Follow up and clinical outcomes:the two cases,who had only bone osteolysis remained stable.Of the other three cases who had bone osteolysis associated with pleural effusion,one patient needed interrupted effusion drainage with stable bone impairment and the other two cases were out of contact.Conclusions GSS is a rare disorder charactcrized by progressive osteoIysis.The clinical presentations of this disease are variable and depend on the sites of involvement.There were no standard therapy available.Prognosis depends on the site of involvement,extent of the disease and presence of complications.Those who have plueral effusion had poor prognosis.

Objectives Aiming at the current health management mode of chronic disease preven-tion and control as the focus of work, this paper was to evaluate the effect of chronic disease management-based education on clinical teaching and training in cardiovascular medicine. Methods Totally 54 students participating in internship training in Department of Cardiology, the Shanghai Ninth People’s Hospital be-tween July 2013 and Aug 2014 were enrolled. Twenty-eight students were taught by chronic disease man-agement-based method while twenty-six students were taught by traditional method. After the internship training in cardiology, final examination (theoretical exam, skill appraisal and case analysis) were compared between the two groups to assess the teaching efficacy. Questionnaire survey was employed to investigate student satisfaction with chronic disease management-based teaching method. Data were analyzed by SPSS 13.0 software. Quantitative data or enumeration data between two groups were compared by t-test or chi-square test respectively. Results There was no significant difference in the theoretical exam score between two groups (P=0.422). However, the scores of skill appraisal and case analysis in students taught by chronic disease management-based method were significantly higher than those in students taught by traditional method (P<0.05). Most students taught by chronic disease management-based method were satisfied with the novel teaching method. Conclusion In the course of clinical medicine education, the emphasis on the management of chronic diseases can not only significantly improve the quality of clinical teaching in car-diovascular medicine, but also lay the foundation for the implementation of the concept of chronic disease management.
