Objective To study the effects of the staging acupuncture combined with physical therapy on the neural function, motor function and activities of daily living in stroke patients. Methods 166 cases were divided into two groups: 83 cases in the treatment group were treated with staging acupuncture combined with physical therapy; 83 cases in the control group were treated with traditional acupuncture combined with physical therapy. They were evaluated with modified Edinburgh-Scandinavia Stroke Scale (MESSS)，Fugl-Meyer Assessment (FMA), and Bathel Index (BI) before and 2 months after treatment. Results There was no significant difference between these 2 groups before treatment (P>0.05), but were significant differences in MESSS, FMA and BI (P<0.05) after treatment. The incidence of recovery after treatment was 90.36% in treatment group, significantly better than that of the control group (74.49%, P<0.05). Conclusion In comparison with the traditional acupuncture, the staging acupuncture can significantly improve the effect on stroke based on the physical therapy.

Objective To explore the influence factors and the status of anxiety and depression in main caregivers with cerebral palsy children , improve caregivers psychological health status , and offer references for improving the rehabilitation level of cerebral palsy children .Methods A total of 145 caregivers of cerebral palsy children were selected by cluster sampling to carry on the investigation by using SAS , SDS, WHOQOL-BREF. Results The incidence of anxiety and depression was 42.76%and 53.79%, respectively.The score of anxiety was 47.73 ±10.96, which was higher significantly than domestic routine norm (29.78 ±0.46) with a statistical difference (t =19.730; P <0.01).Anxiety and depression score increased as the life quality score of increased.The single factor analysis results indicated that there was a statistical significance in rate of anxiety among different jobs, education levels,ages,monthly income,and with complications or not (χ2 =11.695, 10.787, 3.919, 5.133, 9.942, respectively; P<0.05), so did the depression among different genders ,and age groups (χ2 =10.393 and 8.919; P<0.05).Multivariate Logistic stepwise regression analysis found the results as following:female caregivers , with complications , and half-paidcombining with New Rural Cooperative Medical System (NRCMS) were easier to have the depressed mood .Workers, peasants, and course of disease above 10 years appeared anxiety easily .Conclusions The caregivers of cerebral palsy children psychological status are relatively poor in hospital , which exists seriously anxious and depression .Medical workers should pay attention to the psychological changes of main caregivers , offering health education and psychological care during the treatment.For there have been mental illness caregivers , it is recommended for them to receive timely psychological treatment , thereby improving the rehabilitation level of cerebral palsy children in an all -round way.

OBJECTIVETo elucidate the dietary exposure to deoxynivalenol (DON) and zearalenone (ZEN) from cereal-based products in Chinese populations using the probabilistic assessment approach.

METHODSA total of 292 wheat flours and 347 corn-based products were collected from sampling sites of 107 supermarkets or farmers markets, which were randomly selected from 44 cities of 13 provinces in 2009 by the stratified cluster random sampling method. Then, DON and ZEN contamination levels in these samples above analyzed by UPLC-MS/MS in combination with the food consumption data of 68 959 respondents, who were divided into group 1 aged 3 to 13 years old, and group 2 aged 14 and over 14 years old (≥14 years old), obtained by China National Nutrition and Health Survey in 2002 were investigated. A probabilistic assessment model using Monte Carlo simulation was applied to derive the intake distribution of P(1)-P(99) percentile of dietary exposure to DON and ZEN. Meanwhile, all parameters related to dietary exposure to both toxins were compared with either the provisional maximum tolerable daily intake (PMTDI) of 1 µg·kg(-1)·d(-1) for DON, or the tolerable daily intake (TDI) of 0.25 µg·kg(-1)·d(-1) for ZEN in order to evaluate the risk of dietary intake of two toxins and find the minimum percentile of dietary exposure to these two toxins. The statistical differences of dietary exposure to these two toxins between two groups were achieved by t test.

RESULTSThe detection frequencies of DON in wheat flours and corn-based products were 100% (292/292) and 97.4% (338/347), respectively. A total of 21 out of 639 samples (wheat flours: 5/292, corn-based products: 16/347) were positive for DON at the levels exceeding the Chinese regulatory limit of 1 000 µg/kg for DON. And the detection frequencies of ZEN in wheat flours and corn-based products were 53.4% (156/292) and 87.6% (304/347), respectively.54 out of 347 corn-based products and no wheat flours were positive for ZEN at the levels exceeding the Chinese regulatory limit of 60 µg/kg for ZEN. Meanwhile, the mean values (95% CI) of the P(50), P(75), P(90), P(95), P(97.5) and P(99) percentile of dietary exposure to DON in populations of 3 to 13 years old were 0.170 (0.170-0.171), 0.762 (0.759-0.765), 2.066 (2.038-2.069), 3.515 (3.501-3.530), 5.342 (5.314-5.372), and 9.220 (9.155-9.279) µg · kg(-1)·d(-1), which were higher than those in populations of ≥14 years old (0.131 (0.130-0.131), 0.500 (0.498-0.501), 1.280 (1.276-1.285), 2.138 (2.128-2.14), 3.510 (3.494-3.527), and 5.512 (5.474-5.546) µg·kg(-1)·d(-1)), with t values of 87.19, 163.87, 164.66, 157.78, 105.47 and 96.31, and all P values less than 0.001. And the mean values (95% CI) of the P(50), P(75), P(90), P(95), P(97.5) and P(99) percentile of dietary exposure to ZEN in populations of 3 to 13 years old were 0.001 (0.001-0.001), 0.006 (0.006-0.006), 0.039 (0.038-0.039), 0.101 (0.100-0.101), 0.195 (0.194-0.197) and 0.378 (0.374-0.381) µg · kg(-1)·d(-1), which were also higher than those in populations of ≥14 years old (0.001 (0.001-0.001), 0.004 (0.004-0.004), 0.026 (0.026-0.026), 0.061 (0.060-0.061), 0.115 (0.115-0.116) and 0.232 (0.231-0.235) µg·kg(-1)·d(-1)) with T-values of 151.11, 73.80, 96.81, 100.81, 91.93 and 76.13, and all P values less than 0.001. Besides, the minimum percentile of dietary exposure to DON in populations of 3 to 13 years old and ≥14 years old exceeded the corresponding PMTDI of 1 µg·kg(-1)·d(-1) was found in the probability distribution of P(76) (99% percentile = 1.03 µg·kg(-1)·d(-1)) and P(84) (95% percentile = 1.01 µg·kg(-1)·d(-1)) percentile, respectively. And the minimum percentile of dietary exposure to ZEN in populations of 3 to 13 years old and ≥14 years old exceeded the corresponding TDI of 0.25 µg·kg(-1)·d(-1) was found in the probability distribution of P(97) (95% percentile = 0.25 µg·kg(-1)·d(-1)) and P(98) (90% percentile = 0.26 µg·kg(-1)·d(-1)) percentile, respectively.

CONCLUSIONThe contamination levels of DON and ZEN in wheat flours and corn-based products and the risk of dietary exposure to both DON and ZEN in populations in Chinese populations were at relatively low levels. The dietary exposure to both DON and ZEN in populations of 3 to 13 years old was higher than those in populations of ≥14 years old . Populations of 3 to 13 years old were the populations at the high risk of dietary exposure to both mycotoxins.
