BACKGROUND: The risks in pregnancy to the developing fetus result in cerebral palsy after delivery. Therefore, the study on etiology of cerebral palsy should transfer to biological field of embryonic development and stress on multi-factor analysis on relevant environment of pregnant mother,hereditary factors and relevant diseases.OBJECTIVE: To analyze the main risks of incidence of infantile cerebral palsy.DESIGN: Pair design at ratio of 1:2 and Logistic regression analysis of multi-factors were applied.SETTING: Prevention Medical Research Room of Jiamusi University and Department of Epidemiology, College of Public Health, Harbin Medical University.PARTICIPANTS: Totally 103 cases of infantile cerebral palsy were collected from Jiamusi Treatment and Education Center of Cerebral palsy,Shanyang Pediatrics Hospital and Qingdao Pediatrics Hospital from December 2002 to September 2003, of which, 68 cases were male and 35 cases were female. The guardians were in the know and agreed with the investigation. The pair principle at ratio of 1:2 was adopted, based on which, 206 cases of sick children with non-cerebral palsy and disorders in neurological system and healthy children treated at same period in the hospitals were collected as the control. The match conditions in the control were same sex, same nationality and difference in age ± 3 months.sy and healthy children was self-designed. The investigated items included mainly: Factors before delivery (hereditary factors): family history of similar disease; mother's factor: general situations, such as occupation, educational background and age of delivery; behavioral factors of birth: including times of pregnancy, times of delivery and abnormal delivery; healthcare and nutrient in pregnancy: such as examination before delivery and intakes of various foods; sickness or abnormal manifestations in pregnancy: including pathogen infection, pregnant syndromes and vaginal bleeding; medication in pregnancy, fetal placents factors: such as neck winding, mass weight of birth, twin pregnancy, factors during delivery (complications in delivery,methods of delivery) and neonatal factors (various kinds of disorders in neonates). Questionnaire of investigation was performed by looking-up medanalysis was done on single factor and multi-factors. The factors that presented statistical significance in single-factor analysis, significant difference (P ＜ 0.05) and P value near to 0.05 were adopted to establish the model of multiple Logistic regression of main risks of cerebral palsy and conditional Logistic regression analysis was carried on.MAIN OUTCOME MEASURES: Analysis on the effects of factors before delivery, during delivery and in neonatal phase on incidence of cerebral palsy.RESULTS: Totally 103 cases of cerebral palsy and 206 cases of healthy factors: Occupation of mother was associated with cerebral palsy. Worker and age ≥34 years were the risks of cerebral palsy (OR=13.333, 2.864,eating fish and sea products in pregnancy, pre-delivery body temperature,mass weight of birth ＞ 4 000 g and pregnant weeks of 37 to 42 were the protective factors of cerebral palsy (OR=0.028-0.576, P ＜ 0.05-0.01); abnormal delivery history and vaginal bleeding in pregnancy were the risks of ery: Apgar score and caesarian section were the protective factors of cerebral palsy (OR=0.458, 0.343, P ＜ 0.01); forceps delivery and delivery with oxytocin were the risks ofcerebral palsy (OR=16.338, 2.116, P ＜ 0.01,of newborn and neonatal intracranial hemorrhage were the risks of cerebral sion analysis: Forceps delivery was the highest risk (OR =70.668) and the sequence risk degree from high to low was asphyxia of newborn, elder age of pregnant mother, vaginal bleeding in pregnancy and abnormal mass weight of birth (OR=19.083-4.138, P ＜ 0.05-0.01). Eating fish and sea products in pregnancy and caesarian section were the protective factors (OR=0.324; 0.262, P ＜ 0.01, 0.05).CONCLUSION: Risks of cerebral palsy are mainly focused on pregnant period and perinatal period. It is suggested to prevent and eliminate actively various risks of cerebral palsy before, during and after delivery (such as forceps delivery, asphyxia of newborn, elder age of pregnant mother,vaginal bleeding in pregnancy and abnormal mass weight of birth) so as to reduce the incidence rate of cerebral palsy.

AIM: This study is to detail its possible mechanisms that homocysteine (Hcy) induces injury of cultured endothelial cells.METHODS: Hcy in sequential concentrations was added into the cultured human umbilial vein endothelial cells for 24 hours in serum-free medium. The lipid peroxidation, release of LDH, cell total protein content, cell apoptosis and necrosis were assessed. RESULTS: Hcy increased the apoptosis of endothelial cells.In high Hcy concentration the cells also showed obvious injurious and necrotic morphological changes. Lipid peroxidation increased, with LDH releasing up and cell total protein content down, and they showed a positive dose-effect relationship with the Hcy concentration. All the above effects of Hcy was strengthened by low density lipoprotein (LDL) which may suggest synergetic effects of Hcy and LDL.CONCLUSION: Our results indicate that Hcy has a strong oxidizing effect, which may be one of its major mechanism for injury of EC.

Objective To study the reliability and validity of the Chinese version of the dynamic occupational therapy cognitive assessment for children (DOTCA-Ch).Methods The English version of the DOTCA-Ch was translated into Chinese. One hundred and nine students from the city of Jiamusi were assessed with the Chinese Binet intelligence test and the DOTCA-Ch. Intra-class correlation coefficients (ICCs) were used in inter-rater and intra-rater reliability assessments. Cronbach's alpha coefficient was used to assess internal consistency. Factor analysis was used to assess construct validity. Pearson correlation coefficients were used in assessing criterion-related validity. Results The total ICC of the DOTCA-Ch was 0. 892. Cronbach's alpha coefficients for the subtests were orientation 0. 713 ; spatial perception 0. 793 ; praxis 0. 850 ; visuomotor construction 0. 844 and thinking operations 0. 630. The ICC for intra-rater reliability was 0. 991 and for inter-rater reliability it was 0. 989. Using the Binet intelligence test as a benchmark, the Pearson correlation coefficient between the IQ values and the total DOTCA-Ch scores was 0. 872 for 6 year-olds, but 0. 870 for 11 and 12 yearolds. Factor analysis revealed an acceptable set of 5 common factors. Their cumulative contribution was 67％.Conclusions The Chinese version of the DOTCA-Ch is reliable and valid. It can be used as an effective measuring tool to evaluate children's cognitive functioning.

ObjectiveTo investigate the distribution of types of human papillomavirus(HPV)in cervical cancer Xinjiang Uyghur women.MethodsFrom june 2008 to April 2010,patients in the gynecological departmen of people's Hospital of Xinjiang Uygur Autonomous Region,who was gidiagnosed cervical cancer and came from southern of Xinjiang.Cervical cells of these patients were collected,HPV genotyping DNA chip was used to detect HP-DNA of each collected sample.ResultsTotally 120 wommen were screened,the infecton rationof HPV was 95.8%(115/120).The positive rate of HPV-16 infection was 69.6%(80/115);other highrisk HPV infection rates were ranked from high to low as HPV-56,HPV-33,HPV-18,HPV-45,HPV-58,HPV-51,HPV-59,HPV-31,HPV-52,HPV-39,HPV-68,HPV-73,low-risk HPV infection rates were ranked from high to low as HPV-11,HPV-42,HPV-43,HPV-6.However,HPV-35,HPV-53,HPV-66,HPV83,HPV-MM4 and HPV-44 were not detected.Single infection of HPV16 or HPV56 was 53.9%(62/115)and 17.4(20/115)respectively,ultiple infection rate was 29.6%(34/115).ConclusionHPV-16 is the most common types in cervical cancer of Xinjiang Uyghur women.HPV56 maybe susceptible to the Xinjiang Uyghur women,reflecting the specificity of HPV infection in cervical cancer of Xinjiang Uygur women.It needs deep study to development a suitable HPV vaccines.
