Objective To explore imaging features of the lateral atlanto-dental interval (LADI) of atlanto-axial joint and its value in the diagnosis of atlanto-axial joint dislocation/subluxation. Methods Two hurdred and forty healthy volunteers without atlanto-axial joint dysfunction and 32 patients with torticollis and/or functional impairment at atlanto-axial joint were enrolled into this study. All subjects were examined with multi-slice CT in both neutral and max rotation positions to the left/right. Clinical endpoints including VBLADI, variance range of the VBLADI and asymmetric conditions were evaluated. x2 test is used to evaluate the variance of incidence of bilateral LADI asymmetry in different age groups, Pearson-test(2-tailed) is used to evaluate the correlation between VBLADI and rotary function of atlanto-axial joint,precise test of fourfold table is used to compare normal group with patient groups. Results ( 1 ) In the normal control group: asymmetry of bilateral LADI were observed in 204 among 240 (85.00%) healthy volunteers including 60 youngsters( < 15 years) and 180 adults( ≥ 15 years). The median and P95% of |VBLADI| were 0.850 mm,2.450 mm in the young ( < 15 years) and 0.700 mm,2.051 mm in the adult(≥15 years),there were 2 and 10 volunteers whose |VBLADI| ≥P95% in the young and in the adult respectively. There was no correlation between VBLADI( -2.146 to 2.114 mm,Median 0.000 mm) and LA(22.949° to 44.649°, Median 34.500°), RA (25.284° to 45.334°, Median 35.300° ), VLRA ( - 11.643°to 8.623 °, median 0.000 ° ) respectively in normal people ( r = - 0.030, - 0.005,0.026, P > 0.05 ). ( 2 ) In the study with 32 patients including 25 youngsters( < 15 years) and 7 adults( ≥ 15 years). Seventeen of 32 had atlanto-axial lateral subdislocation (AALSD),in 16 youngsters( < 15 years), the median of the |VBLADI| was 3.350 mm and 14 cases |VBLADI| ≥2.450 mm;1 adult patient(≥ 15 years) had |VBLADI| ≥ 2.051 mm; 7 of 32 patients had atlanto-axial rotatory dislocation (AARD) including 4 youngsters |VBLADI| <2.450 mm,median 1.200 mm,3 adults |VBLADI| <2.051 mm,all of the 7 patients with AARD had unilateral parasol LADI in neutral position;8 of 32 patients had atlanto-axial complicated dislocation(AACD) including 5 youngsters |VBLADI| ≥2.450 mm,3 adults |VBLADI| ≥2.051 mm. There are more cases whose |VBLADI| ≥P95% in group AALSD and group AACD than in abnormal group( P<0.01 ), but there is no difference between group AARD and normal group( P = 0.738 ).Conclusion The imaging finding of "asymmetry of bilateral LADI" may be either a physiological variation or a pathological condition, clinical manifestations and other imaging findings should be evaluated to make a diagnosis.

Objective To screen the indicator system of sub-health.Methods Three rounds delphi consultations were conducted for selected indicators of sub-health.30 experts were selected for the three rounds' consultations.Results The experts who had been invited are from about 10 different majors and have been engaged in their current profession for 21.75 years on average.The enthusiasm coefficient of specialists in pretest and two rounds' formal consultations were 90.00%, 93.33% and 89.29% respectively.The coordination coefficients Kendall' W of the experts' opinion were 0.327,0.185 and 0.249 respectively.The weight of the first grade indexes of the sub-health namely physical, mental and social sub-health indicator dimension were 40.61%, 33.34%and 26.05% respectively.After two rounds' formal consultation,64 assessing indicators were remained in the final.Conclusion It is practical,efficient and successful to use Delphi method in screening indicator system of assessing sub-health.

The education of rehabilitation therapy specialty is the important task and content of the modern rehabilitation medicine education. The professionals of rehabilitation therapy are far from the needs of the further development of rehabilitation medicine, therefore the education of professionals are more important. Many Medical Colleges began with the education of rehabilitation therapy specialty. Basing on the traditional educational mode, we tried to reform and innovate in all ways including educational ideas, educational concepts, educational Methods , educational contents, and educational instruments and so on to develop the rehabilitation therapists with modern ideas.

Objective To search for a treatment approach for scalp avulsion injury based on the clinical experiences and review of literature.Methods Twenty-six consecutive scalp avulsion cases were involved in the study:15 cases were complete scalp avulsion (5 including forehead skin) and 11 cases were partial scalp avulsion.Cranial bones exposure occurred in 16 cases,11 of which had a size over 4 × 4 cm2.The treatment methods were various:11 cases with microsurgical replantation,9 cases with skin grafting,4 cases with secondary skin grafting followed by multiple drilling of the calvarium,1 case with local flap,and 1 case with free flap.According to the clinical cases and literature reviews,authors tried to search for an optimal protocol.Results Patients with microsurgical replantation achieved the best recovery including hair growth.In case of not qualified or fail to microsurgical replantation,skin graft could be considered as an alterative step,whereas the result of it was no hair growth and usually scar healing.In summary,14 different clinical conditions followed with 10 surgical techniques were concluded in a route chart.Conclusions To achieve the optimal outcomes of scalp avulsion injury,proper techniques should be chosen according to the treatment protocols.

Objective:
New infectious diseases have become a global problem that seriously threatens human life and health and social development, which greatly increases the demand of CT examination for outpatients with fever. Through the discussion of the examination room design of the special CT for epidemic prevention, it can provide reference for medical institutions and reduce cross infection.
Methods:
Based on the requirements of CT equipment installation and environment, combined with the special requirements of epidemic prevention in fever clinic, the paper analyzed the location of examination room, room layout, site construction method, air purification and disinfection, intelligent image aided diagnosis of special CT for epidemic prevention, and put forward the design scheme.
Results:
Through the detailed analysis of the key points of engineering technology and the requirements of infection prevention and control of CT examination room, the design scheme of the examination room was given.
Conclusions
The establishment of special CT for epidemic prevention can meet the needs of clinical examination and effectively reduce cross infection. The design scheme given in this paper has certain reference value and can provide effective help for medical institution.
