ObjectiveTo observe the effect of proprioception disturbance on the activities of daily living (ADL) after stroke.Methods67 stroke patients were divided into group A (32 cases with proprioception disturbance) and group B (35 cases without proprioception disturbance) according to if having proprioception disturbance. All patients of two groups were treated with routine medicine and rehabilitation treatment. Modified Barthel Index (MBI) was used to assess ADL when admission and 8 weeks later.ResultsIn all 67 stroke patients, the incidence of proprioception disturbance was 48.6%. After 8 weeks treatment, MBI scores of both groups improved significantly (P<0.05～0.01) and the average scores of group A was obviously lower than that of group B (P<0.05).ConclusionProprioception disturbance has bad affect on recovery of ADL after stroke obviously. Examination for proprioception disturbance should be performed in early stage after stroke and rehabilitation training should be carried on as soon as possible.

Abstract: At present, nucleic acid detection technology based on the PCR principle is commonly used to detect malaria parasites, the existing Plasmodium detection methods mainly include microscopy, antigen immunoassay, and nucleic acid detection,but due to the long detection time, high personnel and equipment requirements, and other shortcomings, its popularization, and application at the grassroots level are limited. What challenges previous Plasmodium detection methods are the lack of experienced professionals and advanced equipment at the grassroots as well as the requirement of rapid detection of large samples under extreme conditions. The isothermal amplification technology developed in recent years has potential application prospects due to its simplicity, rapidity, high sensitivity, and high specificity. This article attempts to review the principles, characteristics, and prospects of various isothermal amplification technologies, and on this basis, focuses on the introduction of recombinase polymerase amplification (RPA) and recombinase⁃aided isothermal amplification (RAA) assay technologies and proposes the use of such recombinant enzyme amplification technologies to achieve rapid and accurate diagnosis of common Plasmodium species possibility and imagination.

Objective To introduce small group learning in the course of introduction to gen-eral practice to cultivate students' ability of active learning and innovation. Methods Totally 221 students of 2008 grade A and B classes were enrolled as teaching objects and were divided into 20 groups. Introduction to general practice was used as learning materials. One week before the class, teacher gave students learning task and A and B classes carried on class discussion respectively. Re-view speaking was conducted by the representatives of groups. Effectiveness was evaluated through the observation,interview,questionnaire survey and answer scoring points. Results Overall support per-centage to small group learning was 91%. Percentages of students who believed that small group learn-ing was beneficial to cultivating the ability of active learning and innovation were 88% and 73% re-spectively. Conclusions Introducing small group learning in the course of introduction to general practice is effective and conductive to training students' ability to study and innovate.

Objective To investigate the expression of caspase-10 in differentiated thyroid carcinoma and association with its development and metastasis. Methods Thyroid samples from 37 patients in a period from January 2006 to December 2007, with differentiated thyroid carcinoma were retrospectively analyzed for caspase-10 by immunohistocbemistry(streptavidin-perosidase, S-P), compared to control group of 46 cases with nodtdar goiter. The relationship between the expression of caspase-10 and the clinical pathologic characteristics of thyroid carcinoma were also explored simultaneously. Results caspase-10 were observed as brown or yellow particles located in the cytoplasm or cell membrane of nodular goiter but there were no significant evidence for its positive expression in thyroid carcinoma, caspase-10 expression was markedly down-regulated in differentiated thyroid carcinoma(29.73%,11/37) compared with benign nodules(71.74%,33/46, χ2=14.528, P<0.01). The positive expression in 18 cases with lymph node metastasis(11.11%,2/18) was significantly lower than those in 19 patients without lymph node metastasis(47.37%,9/19; χ2=4.210, P<0.01). There was no significant correlation(P> 0.05) between the expression of caspase-10 and the clinical pathologic characteristics including male, age, TNM stage and pathologic type. Conclusion Down-regulation of caspase-10 may play a critical role in carcinogenesis and development of differentiated thyroid carcinoma.

Objective To find out the iodine nutritional status of children in Xiamen island, and to provide the scientific basis for iodine supplimentation. Methods On March 2010, thyroids of all children aged 6to 12, from primary school on the Xiaodeng island of Xiamen were examined by palpation, urinary iodine, iodine content of salt athome and IQ level were tested, and were collected 20 households, iodine content of drinking water was tested randomly. Results IQ testing and thyroid palpation were carried out among a total of 156 children, the goiter rate of children was 1.28% (2/156), the mean IQ was 110; 154 urine samples were taken, the median urinary iodine was 219.1 μg/L; a total of 153 salt samples were tested, and the qualified rate of iodized salt was 87.58%(134/153), and the mean iodine content in the tap water was 4.52 μg/L Conclusions Iodine nutritional status of the island residents is better, and there are no such problems as excessive iodine.

Objective To construct eukaryotic expression vector of wild type E 4F1 and the mutant deleting amino acid region 32-81, and to detect the interaction between wild type or mutant E 4F1 and p53 and to study the effect of E4F1 on the expression level of p21.Methods Wild type and mutant sequences of E 4F1 were amplified from the mammary library using standard PCR and recombinant PCR .The sequences were cloned into pXJ 40-MYC vector to generate the MYC-E4F1 and MYC-E4F1(Δ32-81) recombinant plasmids that were transfected into 293T cells and identified by Western blotting . FLAG-p53 and MYC-E4F1 or MYC-E4F1(Δ32-81) were co-transfected into 293T cells and immunoprecipitation assay was performed to detect the interaction of wild type or mutant E 4F1 with p53.Wild type and mutant E4F1 expressing vec-tors were co-transfected into osteosarcoma U2OS cells and the expression of p21was detected.Results Recombinant plas-mids of MYC-E4F1 and MYC-E4F1(Δ32-81) were successfully constructed.Both wild type and mutant E4F1 interacted with p53.Deletion of amino acid region 32-81 of E4F1 increased the interaction .The expression level of p21 was in-creased by wild-type E4F1, but not by mutant E4F1.Conclusion The eukaryotic expression vector of wild type E4F1 and its deletion mutant is successfully constructed .Both of them interact with p53.Deletion of amino acid region 32-81 of E4F1 increases the interaction .This study contributes to further studies on the regulation and mechanism of E 4F1 on p53.

OBJECTIVETo analyze the reliability and validity of Instrument zur stre beta bezogenen Tätigkeitsanalyse 6.0 (ISTA 6.0).

METHODS991 participants were sampled with stratified cluster randomly methods from various kinds of occupations, including teachers in primary and middle schools, doctors, bankers and environmental protection officers in order to study the reliability and validity of ISTA 6.0 with inter-item consistency and construct validity.

RESULTSThe Cronbach's alpha coefficient of ISTA 6.0 was over 0.7 with exception of Cooperation closeness (KOP) and Cooperation requirements (KER). Single factor analysis of construct validity of ISTA showed that the first and fifth subitem of Complexity (AK), the fifth subitem of Task control (HS) and Work organization problems (AOP) had lower factor loading (P < 0.05). The multilevel confirmatory factor analysis showed that the fit index and factor loading were significantly greater except KER of Regulation possibilities (RR) and Cooperation possibilities (KSP) of Regulation possibilities (RP). The non-normed fit index (NNFI) and Comparative fit index (CFI) were lower than 0.9, possibly because of irrationality of some subitems and lower factor loading of KER and KSP factor. It implied that Chinese edition of ISTA6.0 needed further improvement according to the modification index (MI) and the special knowledge for higher construct validity.

CONCLUSIONISTA 6.0 can measure truthfully occupational stressors. Owing to the difference of culture, economy and custom, some subitems of ISTA 6.0 does not fit in with Chinese situation. Therefore it will be revised further for use in China.
