OBJECTIVETo explor the curative effect of double pedicle sliding skin flap for correction of cryptotia.

METHODSFrom January 2011 to October 2014, 7 cases with cryptotia (12 ears) were treated. We designed a double pedicle sliding skin flap above the helix. The flap was slided downward to form a new auriculocephalic sulcus. The other wound was covered by skin graft.

RESULTSAll wounds healed very well with no complication. The follow-up period ranged from 3 months to 1 year, with an average of (5.67 ± 3.38) months. The ear had stable appearance with no recurrence. The result was satisfactory.

CONCLUSIONSThe method is simple with reliable flap survival rates. The new auriculocephalic sulcus is stable and resistant. It's a good choice for correction of cryptotia.

Objective: To investigate the function of the heath expenditure in the role of the economic growth through the research on the effect by the human capital. Methods: To establish endogenous growth models and human capital growth models of simultaneous equations, to analyze the mechanism by the method of a three-stage least squares. Results: Growth of human capital is positively related to economic growth, health expenditure growth is negatively related to economic growth, health expenditure growth and growth of human capital is positively correlated. Conclusion: Influences of health expenditure growth on economic growth depends on the comprehensive response.

To analyze the relationship between hospital non-price competition behavior and market structure, analyze the relationship between hospital market construction and health care costs gtowth. Methods:Using cross-province data(SCP) theory to establish the regression function of health cost expenditure, hospital market concentration ratio and the occupancy of public hospital market, process the empirical analysis based on the two-factor effectiveness model of panel data. Results: There is no medical arms race in hospital business under the current market concentration. Conclusion: The reinforcement of market competition played a more important role in the improvement of operational efficiency rather than the differences in the nature of property rights and the profit of hospitals.

Objective:To investigate the function of the quality factor in the growth of the total heath expenditure, in order to provide references for making the object of the health policy. Methods: Through the decomposition the identical equation of the growth of the total expenditure on health, to analyze the contribution of medical service quality and its factor. Results: The sustaining improvement of medical service quality in the important factor on the constant growth of the total expenditure on health. Conclusion: The primary objective of health policy is to improve the quality of medical services, and the secondary is to control the expense.

To investigate the possibility of resection arthroplasty of the sternoclavicular joint in treatment of dislocation of this joint.Methods:Five patients who had had resection arthroplasty of the sternoclavicular joint and in whom the costoclavicular ligament had to be reconstructed,follow-up averaged 1.8 years.Results:The average duration of follow-up were 1.8 years.All of the patients had an excellent result,no cases had infection、pain and abnormalities.Conclusion:We believe that resection arthroplasty of the sternoclavicular joint and preservation reconstruction of the costoclavicular joint is essential,and it is a satisfactory and safe way for the treatment of dislocation of the sternoclavicular joint.

Methods From Feb. till Mar. 2005 and from Sep. till Oct. 2006, the residents living in 4 functional districts in Lu'an city, Anhui Province for one year or more were investigated by questionnaire. The investigation involved the general status, noise perception, behavior, adjustability and so on. 952 available questionnaires from 84 sites were attained. Results The significant differences were seen in the environmental noise perception among sex, age, occupation and health status (P

Objective To assess the value of CT, PET, PET/CT in diagnosis of peritoneal metastases with Meta analysis. Methods Articles of CT, PET or PET/CT on peritoneal metastases published in English or Chinese from Jan 2000 to May 2008 were collected, and histopathological and (or) surgical findings were taken as golden standards. The sensitivity, specificity, summary receiver operating characteristic (SROC) curves, area under the curve (AUC) and the heterogeneity were calculated with software of SAS 8.0, Meta-DiSc 1.4 and STATA 10.0. Results The results of Meta analysis from 11selected articals showed that PET had the highest pooled specificity [0.96, (0.91-0.98)];PET/CT had highest pooled sensitivity [0.77, (0.67-0.85)]. The AUC and Q~* of PET, PET/CT and CT was (0.92, 0.85), (0.99, 0.96), (0.91, 0.84), respectively. AUC of PET/CT was higher than that of CT (Z=2.33, P<0.05). Conclusion PET/CT is a high accuracy diagnostic tool for detecting peritoneal metastases.

ObjectiveTo evaluate the ability of high resolution magnetic resonance (MR) imaging at 3.0 tesla to depict the characterization of human carotid arterial vessel wall and detect atherosclerotic lesions ex vivo in comparison to histopathologic results. MethodsEighteen carotid arteries obtained from 9 elderly donors underwent fat-suppressed T1 - and T2-weighted MR imaging at 3.0 tesla MR system with a mouse coil. Corresponding histological sections were obtained for the comparison. Correlation between MR images and histopathologic slices was obtained by Pearson or Spearman correlation coefficient.Cohen K was computed to quantify the agreement between MRI and histopathologic findings.Results Lumen area,intima and media area measured on fat-suppressed T2-weighted images showed stronger correlation with the corresponding histopathologic slices [ MRI vs.histopathology:( 27. 53 ± 6. 77 ) mm2 vs.( 25.83 ±6. 69 ) mm2, r2 ＝ 0. 91,P2 ＝ 0. 024, ( 12.31 ± 3. 31 ) mm2 vs.( 12. 28 ± 3.71 ) mm2, r2 ＝ 0. 70, P2 ＝ 0. 020,Median 12. 29 mm2(Min 1.12 mm2, Max 33.18 mm2) vs.Median 11.62 mm2(Min 0.89 mm2, Max 32. 84 mm2 ), r2 ＝ 0. 74, P2 ＝ 0. 016, respectively]. The Cohen K score between the MR imaging and American Heart Association classifications was 0. 74, which corresponds to a good agreement. Conclusions 3.0 T high-resolution multi-sequence MRI can clearly show the structure of ex vivo carotid artery wall and allow quantitative assessment.Fat-suppressed T2Wimaging has a greater advantagein presenting atherosclerotic lesions.

BACKGROUND:Nasolabial fold flap has been widely used in clinical surgery. The facial artery anatomy has been widely used in clinical research. Angular artery dissection is becoming more and more important to nasolabial groove area surgery, but at present, there is a lack of anatomical analysis of internal angular artery.
OBJECTIVE:To study the anatomy of the angular artery, and to provide anatomical data for protecting the nasolabial flap during surgery.
METHODS:Twenty sides of adult cadaver specimens on head and face were dissected. A reference coordinate system was made based on the line between the connection of two medial angles of eyes (axis X) and the facial midline line (axis Y). The location of the angular artery was measured taking A-F as reference points.
RESULTS AND CONCLUSION:(1) The slant angles of the angular artery on BC section, CD section, DE section and EF section were (11.1±4.3)°, (34.1±8.8)°, (21.5±10.5)°, and (17.0±4.7)°, respectively. (2) The angular artery sourced from facial artery was more than it sourced from ophthalmic artery. The diameter of right blood vessel was larger than that of left side. (3) The angular artery sourced from ophthalmic artery comes from the location which extended 8.1 mm to both sides from the point which was 10 mm up from the intersection of facial medial angle of eyes connection and midline. The blood vessel diameter of the starting point was (0.7±0.2) mm. The whole range was 20.1 mm. (4) The angular artery sourced from facial artery comes from the location which extended 25.8 mm to both sides from the point which was 40 mm down to the intersection of facial medial angle of eyes connection and midline. The blood vessel diameter of the starting point was (0.9±0.3) mm. Point to the wing of nose the lateral distance was (5.0±1.2) mm. The whole range was 68.7 mm. The surface projecting of angular artery coming from research results provided anatomic basis for surgery of nasolabial flap.
