Objective:To investigate the continuing education training demands and its related factors in mental health practitioners in China.Methods:The sample of 1391 mental health practitioners was collected from 29 provinces by convenient sampling with the self-made questionnaire.Results:The practitioners had the highest demands for practice(4.2±1.0)and skill training(4.1±1.0).Their training demands could be summarized as three factors:supervision and evaluation,knowledge,practice and skill.The ones who had lower educational level,less work experience,or more knowledge training had more demands for these three kinds of training.For supervision and evaluation training,junior colleges had more demands than doctors [(14.9±3.9)vs.(13.1±3.9),P<0.05],females had more demands than males [(14.8±3.7)vs.(14.3±3.4),P<0.05],and the ones with social orientation had more demands than those with educational or clinical orientation [(15.2±3.6)vs.(14.4±3.6),(14.4±3.6);Ps<0.05].The ones who were part-time workers,trained less times,and skill-trained had more demands for skill training [e.g.part time workers:(8.4±1.6),full time workers:(8.1±1.8);P<0.05].Conclusion:The mental health practitioners have the highest demands for continuing training,especially practice and skill training.The related factors to their demands include gender,age,education level,occupation area and working time.

Complicated characteristic of facial modality acquisition and measurement is commonly needed in clinical environment.Two different methods were compared, one method was acquisition two-dimensional character based on the principle of machine vision with a charge-coupled device (CCD) capturing image, and another method was acquisition three-dimensional character based on the technology of Reverse Engineering with laser scanning capturing image. The principle, composition of the system, calibration and characteristics of different method are analyzed. Two-dimensional and three-dimensional facial data of thirty undergraduates was used to compare different methods. The application and restriction of different methods are concluded. The conclusion of this paper provided a reference for face plastic surgery, facial paralysis, facial surgical evaluation and rehabilitation design.

ObjectiveTo explore the characteristics and correlation of intelligence development and socioemotional development in 1~3 years old children with expressive language disorder,and provide a basis for early intervention.Methods125 cases with expressive language disorder(language disorder group) and 126 normal children (normal group) are evaluated in two parts (intelligence and social mood) with 0~6 years old neuropsychological development diagnosis scale and Chinese version of urban infant-toddler social and emotional assessment.Results (1)The scores in language disorder group were lower than normal group in the area of free movements (81.60±10.40 vs 89.62±7.94),adaptability (81.48±10.95 vs 91.25±8.89),language (67.46±7.20 vs 89.13±8.24),social behavior (76.61±9.73 vs 90.12±8.13) and total developmental quotient (80.17±6.39 vs 91.15±6.05) (P<0.05).(2) There were significant differences between language disorder group and normal group in the area of externalizing behavior(56.28±10.15 vs 53.57±7.91),deregulation (56.45±10.61 vs 51.11±9.32) and capabilities(46.79±9.08 vs 51.25±7.47) (P<0.05).The boys' scores in internalizing behavior were lower than the girls' (49.19±10.76 vs 54.71±9.90) (P<0.05).(3) The scores of gross motor had positive correlation with externalizing behavior (r=0.220,P<0.05).The scores of language had negative correlation with externalizing behavior and deregulation(r=-0.650,P<0.05;r=-0.470,P<0.05).The scores of social behavior had negative correlation with externalizing behavior (r=-0.208,P<0.05).There was also a negative correlation between total development and deregulation (r=-0.184,P<0.05).(4) Multiple stepwise linear regression results showed that the externalizing behavior domain and mothers' education could predict 44.1% of variances in the language area.ConclusionThe children with expressive language disorder not only show backward in level of language development,but also in the development of other areas,and also bad social behavior and emotional problems.Individualized parenting interventions should be adopted to promote these children's intelligent development in an all-round way.

Objective To establish a method of LC-MS/MS for determining cordycepin(Cor)and 3′-deoxyinosine(3′-Deo)concentration in rat plasma,and to study their pharmacokinetics in rats.Methods Protein was precipitated with methanol using 2-chloadenosine(2-Chl)as an internal standard.The chromatography was performed on Kinetex C18(3 mm×100 mm,2.6 μm,Phenomenex,USA)with gradient elution in aqueous(5 mmol·L-1 ammonium acetate)-methanol solution as mobile phase.ESI ion source was used for mass spectrometry,and positive ion multiple reaction monitoring(MRM)was used for scanning detection.The pharmacokinetics of Cor and 3′-Deo after oral administration of Cor(10 mg·kg-1)were studied in rats.Results Cor at 0.5-100 ng·mL-1 and 3′-Deo at 1-200 ng·mL-1 had good linearity,and the lower limits of quantification were 0.5 and 1 ng·mL-1,respectively.After oral administration of Cor in rats,the plasma concentration of Cor was low,which was mainly converted into the metabolite 3′-Deo.The Cmax of Cor and 3′-Deo were(5.4±3.4)and(142.0±50.0)ng·mL-1,and AUC0-360min min were(658.4±459.3)and(18 034.9±4 981.1)ng·min·mL-1,respectively.Conclusion The method is simple,sensi-tive,and accurate,which is suitable for determining Cor and 3′-Deo concentration in plasma and the pharmacokinetic study.

Objective To investigate the prevalence of allergic and infectious diseases in children， and to assess the influence of indoor and outdoor environmental factors on these two common diseases in children. Methods A questionnaire was used to investigate the prevalence of allergic and infectious diseases in 140 children of 7 years old in Laizhou Bay， Shandong Province. Logistic regression was used to analyze the associations between indoor and outdoor environmental factors and children’s allergic and infectious diseases， respectively. Results The prevalence of previous eczema and other allergic diseases for the past year in children was 37.9% and 15.0%， respectively， and the prevalence of infectious diseases for the past year was 35.7%. As for allergic diseases， eye irritation due to outdoor air （ OR =2.977； 95% CI ： 1.407‒6.296） and nose irritation due to outdoor air （ OR =5.147； 95% CI ： 1.272‒20.827） were the risk factors for previous eczema in children. Indoor musty taste increased the risks of urticaria （ OR =4.306； 95% CI ： 1.062‒17.454） and previous eczema （ OR =3.853； 95% CI ： 1.080‒13.743）. The use of cockroach killers indoors increased the risk of rhinitis （ OR =6.102； 95% CI ：1.297‒28.697）. As for infectious diseases， having outdoor pollution sources increased the risk of gastrointestinal infection （ OR =4.937； 95% CI ： 1.050‒23.216）， and the use of mosquito coils and clothing mothproofing agents increased the risks of respiratory （ OR =6.333； 95% CI ： 1.397‒28.714） and gastrointestinal infections （ OR =3.218； 95% CI ： 1.074‒9.644）， respectively. However， we did not find associations between indoor passive smoking and allergic or infectious diseases. Conclusion Except outdoor passive smoking， all the other indoor and outdoor environmental factors increase the risks of children’s allergies and infectious diseases.
