Cerebral palsy (CP) describes a group of disorders of the development of movement and posture,causing activity limitation attributed to disturbances,which occurred in the fetal or infant brain.Early identification and intervention of CP has always been a difficult topic in the research of neuroscience.The intervention should be focused on infants showing early signs of CP.Such signs may be efficiently detected by a combination of neuroimaging and the General Movements Assessment.Besides movements,enriched environments,active participation,parental coaching have benefits to early intervention.In this investigation,the early identification and intervention in cerebral palsy were focused.

OBJECTIVE To investigate the vocational safety protection in nurses in the clinic work,then to enhance the protection consciousness of nurse,and the usage of protection.METHODS The relative questions on the vocational protection were investigated in the nurses from one tiatiary care level hospital in China by the Questionnaire designed by ourselves.RESULTS Among the one hundred and fifty nurses investigated,one hundred and one(67.5%)of them just knew little about the vocational exposure,and one hundred and four thought they just accepted little education of vocational exposure.The average score of the usage of protection appliance was 54.89?14.70.The average score was increasing with the higher degree of the study and with the length of service.CONCLUSIONS The vocational safety protection should be emphasized,the protection appliance should be provided comprehensively,and clinic protection system of full efficiency with long time and ensuring system should be founded.

BACKGROUND: Carboxymethyl chitosan is a water-soluble derivate modified from chitosan, with various biological activities. It is a good ligand of metal ion and can integrate Ca~(2+) to prepare a novel biological material. OBJECTIVE: To explore a method for preparing carboxymethyl chitosan calcium (CCC) and analyze its properties and structure. METHODS: CCC was produced by carboxymethyl ohitosan reacting with solution of calcium chloride. The solubility, carboxymethylation degree, rotational viscosity, and calcium content of CCC were determined, and infrared and ultraviolet spectral analyses were performed.RESULTS AND CONCLUSION: The calcium content of CCC was approximately 15%. Compared with carboxymethyl chitosan, infrared spectrum and ultraviolet spectrum of CCC were changed. The prepared CCC is a new calcium compound through property and structural analysis.

Objective To observe the effect of carboxymethyl chitosan calcium(CCC) on the concentration of lead,calcium,and liver antioxidative capacity in lead poisoned mice.Methods mice were randomly divided into 6 groups.Three test groups were treated with CCC at three doses.The lead poisoned mice model was established by giving water containing lead acetate,and then CCC was administered to mice once a day.After 30 days,the mice were killed and the content of lead in blood,liver,brain and femur were determined by atomic absorption spectrophotometer,and antioxidative capacity in liver was measured using assay kit.Results CCC could reduce the contents of lead in blood,brain,liver and femur significantly,decrease the level of maleicdialdehyde(MDA),increase activities of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and total antioxidative capacity(T-AOC) in liver markedly. Conclusion CCC can promote the excretion of lead,increase the content of calcium in femur and antioxidative capacity in lead poisened mice.

Objective To explore the health guidance role on treating uterine fibroids in high intensity fo-cused ultrasound thermal ablation(HIFU).Methods High intensity focused ultrasound ablation treatment was used in 74 cases of uterine fibroids patients before and after treatment to enable patients to better health guidance with treatment.Results After treatment,symptoms of patients with the clinical manifestation including menstrual too much,dysmenorrhea,frequent urination,constipation and anemia,were significantly improved.The volume of myoma of uterus before treatment and after treatment for 3 months,6 months and 1 year were (100.780 ±104.243 )cm3 , (53.446 ±49.546)cm3,(32.704 ±32.246)cm3 and (21.991 ±16.301)cm3,respectively.The volume of myoma of uterus gradually reduced after treatment as compared with that before treatment,the difference had statistical signifi-cance(t=6.758,186,7.567,all P<0.01).Conclusion Effective health guidance is beneficial to HIFU treatment for patient.
