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.

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.

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.

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.

OBJECTIVE:To provide reference for developing effective interventions to self-medication and promoting reason-able self-medication. METHODS:Questionnaires were designed based on the modified Anderson's behavioral model of health ser-vices. By using cluster sampling,residents were randomly selected from 4 districts of Wuhan city to analyze the self-medication be-havior and its influential factors. RESULTS:Totally 204 questionnaires were sent and 199 were recovered with effective rate of 97.5%. The result showed 47.7% residents who perceived discomfort within 2 weeks medicated themselves,and the rate was high-er thansee the doctor. Among self-medication residents,the rate of mild disease,general and serious disease was separately 50.5%,46.3% and 3.2%. The length of illness<7 d and the length of illness ≥7 d accounted for 95.8% and 4.2%,separately. Cold and cough was the highest cost disease for self-medication. The reasons for selecting self-medication were:no need tosee the doctor(43.2%),trouble-saving(23.1%),high medical costs(14.6%),no time to see the doctor(14.6%). 54.1% residents acquired basic medication knowledge from the past experience,25.5% from other's recommendation,and the other from the inter-net,newspaper and magazines. As for the effect of self-medication in the past one year,75.4% residents considered most were ef-fective. 18.6%had suffered from ADR due to self-medication;the incidence of ADR in the residents reading the instruction was sig-nificantly lower than those not reading the instruction(P<0.05);the ratio of reading the instruction in residents with low education level was significantly lower than that with high education level(P<0.05). Single factor analysis showed that residents'choice of self-medication were significantly influenced by the marital status,education,monthly income,medicare,accessibility of medical institutions,the severity of disease and duration of illness(P<0.05). The proportion of self-medication for married group was sig-nificantly higher than unmarried group;the proportion of self-medication for low education level group was significantly higher than high education level group;the proportion of self-medication for low monthly income group was significantly higher than high monthly income group;the proportion of self-medication for group with business medical insurance or self payment was significant-close to medical institutions;the proportion of self-medication for mild disease group was significantly higher than serious disease group;the proportion of self-medication for length of disease≥7 d was significantly lower than length of disease<7 d. Results of multivariate analysis showed that severity of disease and length of disease were the important influential factors for the choice of self-medication(P<0.05). CONCLUSIONS:Self-medication is common in Wuhan city,and mainly for general and chronic dis-ease. Residents don't pay enough attention to reading the drug instructions. Self-medication is affected by various factors which has a certain health risks.
