The review focus on the utility of high-resolution computed tomography (HRCT)in childhood rheumatic lung disease, including HRCT technique, the normal and abnormal HRCT imaging appearances,then emphasizes and illustrates HRCT imaging futures of several childhood rheumatic lung diseases.

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.

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.

Objective To understand the situation of, mental health and behavior of the residents influenced by the environment noise. 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 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.

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 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.

Objective:To assess the differences among the expressions of p38 mitogen activated protein kinases (MAPK),phospho-p38MAPK and nuclear factor kappa B (NF-κB)in oral lichen planus (OLP)and oral squamous cell carcinoma (OSCC ).Methods:In the study,53 cases of OLP,45 of OSCC,and 18 controls were obtained and 4-μm-thick histological sections were prepared from formalin-fixed paraffin-embedded tissue blocks.The expressions of p38MAPK,phospho-p38MAPK and NF-κB were detected by immunohistochemistry staining.Furthermore,the expressions of p38MAPK and phospho-p38MAPK were detected using Western blotting analyses in the fresh tissues from 1 1 cases of OLP,5 ca-ses of OSCC,and 7 cases of the controls.Results:p38MAPK was over-expressed in the lamina propria, but lowly expressed in the epithelium in OLP group.Phospho-p38MAPK was lower expressed in OLP group than in OSCC and control groups.NF-κB was found over-expressed in the lamina propria in OLP group.p38MAPK was found expressed in all the samples in the 3 groups.The expression of phospho-p38MAPK was observed in 8 (8/11)OLP samples,5 (5/5)OSCC samples and 4 (4/7)controls by Western blotting,but no significant differences were found within the 3 groups.Conclusion:p38MAPK can be detected in normal oral mucosa,OLP and OSCC.phospho-p38MAPK may be related to the onset and progression of OSCC.The role of p38MAPK in OLP is yet to be revealed.
