The discussion and research on the clinical dominant diseases of traditional Chinese medicine （TCM） have attracted increasing attention. Through approaches including modern technology， evidence-based medical methods， and multi-disciplinary treatment， we should construct a sound TCM inheritance and innovation system， establish a collaborative innovation mechanism， and integrate major research projects， striving to make breakthroughs in TCM theory， methodology， standards， and regulation system， promoting the scientific and technological progress of TCM， and thereby improving its curative effect. The China Association of Chinese Medicine （CACM） carried out a series of youth salon seminars for clinical dominant diseases in TCM， discussing and sorting out the advantages of the dominant diseases in clinical diagnosis and treatment of TCM and integrated traditional Chinese and western medicine in specific diseases or fields. Authoritative experts in the industry were invited to give comment and guidance to form a report. Centering on clinical research of dominant diseases， thematic research was carried out in the aspects of practice， human experience-based evidence， and transformation path. Through the systematic study of the dominant diseases， the advantages of TCM in different stages of disease treatment were excavated to constantly improve the prevention and treatment ability of TCM and carry forward the advancement of TCM theory and practice. At the same time， the communication and understanding between traditional Chinese and western medicine were improved， laying the foundation for the further formation of industry guidelines or consensus and comprehensive promotion. These seminars are expected to provide references for the development of policy planning， clinical diagnosis and treatment， health economy， and social services in TCM and lay the foundation for the formation of a new modern diagnosis and treatment system with Chinese characteristics.

Gastroesophageal reflux disease （GERD） is a frequently and commonly occurring disease in clinic. In recent decades， with the development in pathophysiology and drug researches， modern medicine has achieved remarkable progress and results in diagnosis and treatment. However， the treatments for non-erosive reflux disease， refractory gastroesophageal reflux disease， proton pump inhibitor resistance， overlap of disease symptoms， and extraesophageal symptoms are limited and ineffective. Traditional Chinese medicine （TCM） was widely used in clinical practice， which has been proved effective in relieving symptoms and improving the quality of life. Sponsored by China Association of Chinese Medicine （CACM） and undertaken by the Spleen and Stomach Disease Branch of CACM， "the 12^th Youth Salon of Clinical Predominance Disease Series （GERD）" invited 18 authoritative digestive experts of TCM and western medicine to discuss "the difficulties of clinical diagnosis and treatment of GERD and TCM advantages". The focus issues such as modern medical diagnosis and treatment achievements and contributions， improvement and maintenance of symptoms， response to overlapping disease symptoms， reduction and withdrawal of acid suppressors， and treatment of extra-esophageal symptoms were discussed in depth. TCM and western medicine exchanged and complemented each other's strengths， combing the difficulties of modern medical diagnosis and treatment， which clarified the positioning and advantages of TCM and provided guidance for clinical and scientific research.

Objective:To investigate the effect of degassing and peroxidation on metal-ceramic bonding strength of Pd-Ag alloy. Methods:The metal-ceramic interface of group A (peroxidation)and B (degassing)was investigated under scanning electronic micro-scope(SEM)and energy dispersive spectrum (EDS).The bond strength between metal and ceramics was measured using a three-point bend test according to ISO9693.Results:The formation of nodules on the surface of alloy specimens was observed in both groups by SEM.The nodules on the specimens of group A were more densely than those of group B.The diameter of nodules in group B was 1 .5μm approximately.The interface of the metal-ceramic specimens had a clear transition porcelain layer and no hole or slit was present. The mean bonding strength of group A and B was (45.97 ±3.92)MPa and (49.1 1 ±6.42)MPa respectively(P=0.031 ).Conclu-sion:Degassing can improve metal-ceramic bonding strength of Pd-Ag alloy significantly.

BACKGROUNDQuantitative dynamic contrast enhancement MR imaging (DCE-MRI), used to measure properties of tissue microvasculature and tumor angiogenesis, is a promising method for distinguishing benign and malignant tumors and characterizing tumor response to antiangiogenic treatment. The aim of this study was to assess the feasibility of quantitative parameters derived from clinically used DCE-MRI for distinguishing benign from malignant tumors in the sinonasal area, which may be potentially useful for prediction and monitoring of treatment response to chemoradiotherapy of sinonasal tumors.

METHODSOne hundred and forty-three patients with sinonasal tumors, including 78 malignant tumors and 65 benign tumors and tumor-like lesions, underwent clinically used DCE-MRI. Parametric maps were obtained for quantitative parameters including K(trans), kep and ve. Two radiologists reviewed these maps and measured K(trans), kep and ve in the tumor tissue. Data were analyzed using independent T-test or Mann-Whitney U test analysis and receiver operating characteristic curves.

RESULTSK(trans), kep and ve showed significant differences between benign and malignant tumors in the sinonasal area (P = 0.000 1). The accuracy of K(trans), kep and ve in differentiation between benign and malignant sinonasal tumors were 72.0%, 76.2% and 67.1%, respectively. There were significant differences in kep and ve between malignant epithelial sinonasal tumors and lymphomas (P < 0.05). Using a ve value of 0.213 as the threshold value differentiated malignant epithelial tumors from lymphomas with an accuracy of 78.3%, sensitivity of 88.2%, specificity of 68.0%, positive predictive value of 66.7%, and negative predictive value of 90.9%. However, no significant difference in K(trans) and kep was found between malignant epithelial and non-epithelial tumors in the sinonasal area (P > 0.05).

CONCLUSIONSIt is feasible that quantitative parameters of tumors can be derived from clinically used DCE-MRI in the sinonasal region. Preliminary findings suggest an increased value for quantitative DCE-MRI in the evaluation of sinonasal tumors in clinical practice.

Objective This study describes the protective effect of myocardial isehemic post- conditioning on ischemic-reperfused myocardium (I/ R) of diabetic rat and its Signaling mechanism. Methods Healthy SD rats weighing 25O-30Og were divided into 6 groups; (1) Blank control; (2) Ischemia-reperfusion; (3) Post conditioning; (4) Diabetic postconditioning ; (5) Diabetic ischemia-reperfusion; ( 6) Diabetic blank control group. Ten rats in each group were randomly selected. Introduction of diabetic rat model: 65 mg/kg STZ was injected into the intraperitoneal cavity, until 2 consecutive blood glucose measurements≥ 16.65 mmol/L were reached after48h. The diabetic model was successful when rats had following symptoms, such as more drinking, more eating, polyuria, weight loss and epilation. Langendorff isolated rat heart perfusion was used for the experiment. Following parameters were measured and compared: Coronary perfusion flow, myocardial infarct size, western blot for measurement of P-Akt, changes in myocardium and mitochondrian observed by Electron microscopy. Results Blood glucose concentration in diabetic group was (23. 15±2. 16) mmol/L and (4. 16±0. 31) mmol/L in non-diabetic group. There was a significant difference (P <0. 01) between the two groups. There were more coronary flow in post-conditioning groups (Post group and Dpost group) than ischemia-reperfusion groups (IR group and DIR group) (6.5±1.2、5.6±1.0 vs. 3.4±1.0、2.0±1.3). The myocardial infarction size was smaller in post-conditioning groups than in ischemia-reperfusion groups (25.2±2.1、34.2±3.6 vs. 47.5±3.5 、65.2±4.5). There was more expression of P-Akt and the myocardial fibers and mitochondrian in post-conditioning groups were better preserved. Conclusion Postconditioning has protective effects in diabetic rat hearts. The mechanism may be associated with Akt activation.

Objective:To investigate the feasibility of universal newborn hearing screening in countryside in order to provide reliable evidence in launching this program all over the countryside of China. Method:Subjects were 12 638 infants who were born in 9 counties from Jan 2004 to Dec 2005. TEOAE was used for the fast hearing screening. Infants were screened on the 2-7 days after the birth. The re-screening was conducted in 4-6 weeks if failed in the initial screening,and follow-up were provided continually if they also failed in the re-screening. Result; Ten thouand eight hundred and forty-five of 12 638(85. 8%) were screened including 9 963(91. 9%) normal newborns and 882(8. 1%) newborns with high-risk. Seven thouand four hundred and fifty (68. 7%) newborns passed the initial screening, and 3 395 (31. 3%) people failed. One thouand seven hundred and ninty-three (14. 2%) infants were refused to be screened.Only 2 536 (74. 7%) were re-screened on time, and 859(25. 3%) did not receive re-screening. One hundred and twenty were failed in the re-screening or first screening, and 79 (65. 8%)of them received diagnostic assessment. Among the infants received diagnostic assessment, 6(7.6%)ca-ses were found to have profound hearing loss in both ears, 9(11. 4%)cases were found to be severe hearing loss(7 in both ears and 2 in single ear) , 11(13. 9%)cases were found to be moderate hearing loss (5 in both ear and 6 in single ear), 26 (32. 9%) were found to have slight hearing loss (11 in both ear and 15 in single ears), and 27 (34.2%) were normal. Fifty-two infants were diagnosed as hearing loss with a prevalence of congenital hearing loss(in binaural and monaural) of 0. 5%(52/10845)and a prevalence of bilateral hearing loss of 0. 3%(29/10845). A prevalence of congenital hearing loss was 0. 2% (22/9 963) in well infants and 3. 4% (30/882) in high risk infants. Among the 13 cases of children with severe and profound hearing loss in both ears children, 8(61. 5%)cases were fitted with hearing aids and 1 (7. 7%) case was implanted with cochlear implants. Conclusion:It is necessary and feasible to conduct hearing screening program in the rural area. However, the suitable model to perform the program in the countryside needs to be set up as soon as possible in order to get more poor infants to participate into the hearing screening program for free and increase the screening rate.

OBJECTIVE: To evaluate the diagnostic performance of the AllergyScreen system from Mediwiss An alytic GmbH and the Pharmacia CAP system from Pharmacia Diagnostics for the detection of four inhalant allergens in the diagnosis of allergic rhinitis. METHOD: All 35 serum samples were collected from patients who were referred to the allergist for a suspected allergic rhinitis between January to March in 2007. Patients were classified as study diagnosis-positive for inhalant allergy if they both had a positive clinical examination/history and a related positive skin test for the suspected inhalant allergen. RESULT: Comparing with the reference standard, the diagnostic indexes (sensitivity, specificity, accuracy, predictive value of positive, and predictive value of negative) of the CAP system and the AllergyScreen system were 0.96 vs 0.89, 0.84 vs 0.75, 0.89 vs 0.80, 0.78 vs 0.65 and 0.93 vs 0.93 respectively. The CAP system method had higher sensitivity, specificity and accuracy than AllergyScreen system method, but there have no statistical difference between two systems (P>0.05). CONCLUSION This data support the use of ImmunoCAP system and AllergyScreen system to identify potentially significant individual allergens in the diagnosis of allergic rhinitis. The diagnostic indexes between the two systems have no statistical difference. As a simple, rapid turnaround time and low-cost system, AllergyScreen system can test multi-allergens in one time, so it can be used as a complementary with the ImmunoCAP system.
