Objective To analyze epidemiologie and injury characteristics of traffic injuries in Shenzhen through emergency department. Methods A questionnaire was pre-designed to collect data of patients admitted to six general emergency departments of six district in Shenzhen from January 2007 to December 2007 for clinical analysis. Results There were 1 328 patients with road traffic injuries, at age range of 2-84 years (average 31 years). According to occupation, most patients were local workers and migrant workers (57.8%). The accidental vehicles were mostly cars (48.5%). Most accidents (78.6%) occurred in urban streets. As for time distribution of traffic injuries, most injuries happened on Friday and Saturday (accounting for 17.8% and 18.7% respectively), especially on Friday (r = 0.166 0, P <0.01). There was central tendency around 15:35 p.m. in one day (r = 0.285 6, P < 0.01). The age of male was (32.36±8.70) years and that of female (29.96±4.32) years, with statis-tical differences (P < 0.05). Of patients followed up, 84.4% patients could work on their original jobs, 8.5% needed ehange of their jobs and 7.1% lost the ability of work. Conclusions It is neeessary to strengthen road safety education among local workers and migrant workers to improve their awareness of road safety. Traffic administrators and road safety marks should be added in the chief period and districts where road traffic injuries happen most frequently. Controlling the number of small cars may be effective to reduce traffic accidents.

Objective To investigate expressions of microRNA-21 (miR-21),PTEN,NF-κB,and caspase-9 in colon carcinoma and their possible mechanisms in progression of tumor.Methods Expressions of above-mentioned indexes and percentage of apoptotic cells in colon carcinoma,colon adenoma,and normal tissue specimen were detected.Results Expressions of miR-21,PTEN,N F-κB,and caspase9 in normal tissue were 0.39 ±0.02,50％,25％,and 50％.Expressions of them in colon adenoma were 0.62 ±0.06,50％,35％,and 55％,and those in colon carcinoma were 0.88 ±0.04,30％,75％,and 20％.Percentage of apoptotic cells were (24.64 ± 7.66) ％,(15.86 ± 1.44) ％,and (6.20 ± 2.57) ％,respectively.The above P-values were all less than 0.05.Expression of miR-21 was positively correlated with TNM stage,depth of infiltration,differentiated level and expression of NF-κB while inversely correlated with PTEN and caspase-9 expressions and percentage of apoptotic cells.The r-values were 0.647,0.297,0.259,0.519,-0.299,-0.388,and-0.931,respectively.Conclusions Hyperexpression of miR-21 participated in progression of colon carcinoma probably through down-regulating expressions of PTEN and caspase-9 and up-regulating expression of NF-κB and then suppressing cell apoptosis.

Objective:To observe the anatomic characteristics of supratubal recess and the morphological change of it in the sick ear. To investigate the relation between the morphological changes of supratubal recess and otitis media.Method:Using high resolution CT to observe and measure the supratubal recess of the normal ears and the ailing ones.Result:For the normal adults, the anteroposterior diameter of the supratubal recess is(3.83±1.28)mm,the vertical diameter(3.67±1.14)mm,the height(3.76±0.36)mm;and the length of the cog is(2.84±0.38)mm.The size of the supratubal recess showed no significant difference between left and right(P＞0.05).There was no relationship between the size of the supratubal recess and pneumatization of mastoid cells (P＞0.05).There was significant differences in size of the supratubal recess between normal ears and the ears with cholesteatoma(P＜0.05),but there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells(P＞0.05)in the ears with cholesteatoma.There was no significant differences in size of the supratubal recess between normal ears and the ears with chronic otitis media(P＞0.05).In the ears with cholesteatoma,40% had osseous destruction in supratubal recess.Conclusion:For the normal adults, the size of the supratubal recess showed no significant difference between left and right, and there was no relationship between the size of the supratubal recess and pneumatization of mastoid cells. Anterior tympanic isthmus , posterior tympanic isthmus and supratubal recess which is the supplement of the formers constitute the air way between attic and mesotympanum. The supratubal recess of the cholesteatoma is smaller than the normal, when the eustachian tube dysfunction occurs, the air way in the middle ear would herein be affected, and cholesteatoma forms eventually. There was no significant differences in size of the supratubal recess between normal ears and ears with chronic oti-tis media, as in the clinic.The effect of the supratubal recess should be taken into account when we consider the pathogeny and treatment of the middle ear cholesteatoma.

Objective To evaluate the clinical efficacy of integration of traditional Chinese and western medicine (ITWM) or pure western medicine on the patients with immune thrombocytopenia (ITP). Methods Randomized controlled trials (RCTs) on ITWM treatment of ITP were searched in PubMed, EMBASE, Wanfang database, CBMDisc, CNKI and VIP. Quality of the RCTs was evaluated strictly, and statistical analysis was performed with Cochrane Collaboration’s RevMan5.1.7 software. Results Twenty-two trials involving 1527 patients were included. The results of Meta-analysis showed that the ITWM treatment of ITP significantly improved the total effective rate [RR=1.23, 95%CI (1.17, 1.29), P<0.000 01] compared with that of pure western medicine treatment. Funnel plot showed that publication bias was small. Meanwhile, peripheral platelet count and the number of megakaryocyte which can generate platelet in bone marrow increased, obvious advantage was showed in long-term effect, and adverse reactions were reduced with ITWM treatment in ITP patients. Conclusion The existed limited evidences suggest that ITWM treatment of ITP can significantly improve clinical efficacy. The quantity and quality of research literature were limited, and well-designed randomized double-blind controlled trials with large sample and multi-centers are required for a more reliable conclusion.

Objective To assess the interobserver reliability and intraobserver reproducibility of Neer classification system and its influencing factors.Methods The present study reviewed the series preoperative radiographs (including those of scapular anteroposterior view,scapular lateral view and modified Velpeau axillary view and an axial CT scan) of 40 patients who had been treated in our department from January 2010 to December 2010 for proximal humeral fractures.The radiographs were assessed by 12 individual observers on 2 separate occasions with an interval of 3 months at least Half of the observers (the professional group; n =6) had received a shoulder fellowship training and the other half (the control group; n =6) had not All the observers were asked to categorize the radiographs according to the Neer classification system of 16 types of fractures in a same process.The reliability and reproducibility of the system were assessed with the Kappa statistics.Comparisons of classification agreement were made between the professional group and the control group.We also evaluated the simplified Neer system of only 6 types of fractures with recombinant data.Results The interobserver reliability coefficients were 0.534 and 0.473 for the first and second assessments,with an intraobserver reproducibility coefficient of 0.669.The agreement level in the professional group was significantly higher than in the control group ( P ＜ 0.05).The interobserver reliability coefficients of the simplified Neer system were 0.581 and 0.502,with an intraobserver reproducibility coefficient of 0.680.Use of the modified Neer system did not elevate the agreement level beyond the moderate range.The classification was agreed on by all the observers in 17.5％ of the fractures during the first assessment and in 15.0％ during the second assessment.Conclusions Neer classification may have fair interobserver reliability and moderate intraobserver reproducibility.Experience of shoulder fellowship training is an important factor influencing the reliability of the Neer system.Simplification of the system may not help increase its reliability.

Objective:To study the histogenesis and cell differentiation of desmoplastic ameloblastoma.Methods:The expression of various protein filaments was detected by immunohistochemical stainning in 20 cases of desmoplastic ameloblastoma and the ultrastructure of the tumor was observed in 4 cases.Results:CKH,CK8 and CK19 were positive in spindle-shaped and polygonal epithlium tumor cells.Vimentin was positive in mesenchymal fibrocytes and smooth muscle actin in some mesenchymal cells.Ultrastructural observation found that tonifilaments were in epithelial cells and there were desmosomes between these cells.In stroma myofibroblasts were presented.Loose connective tissue could be seen around some epithelial cell nests.Conclusion:Desmoplastic ameloblastoma may be arise from the early stage of the dental germ formation, epithelial cells of the tumor had the tendency to differentiate to the keratinized cells.
