Objective To systematically review the effect of dietary and physical activity interventions on weight management during pregnancy.Methods The PubMed (from Jan.1990 to Sep.2013),Springer (from Jan.1960 to Sep.2013),Willy (from Jan.1990 to Sep.2013),Web of Science (from Jan.1990 to Sep.2013),Wanfang data (from Jan.1995 to Sep.2013),China National Knowledge Infrastructure (CNKI) (from Jan.1995 to Sep.2013)were searched for relevant articles.All published randomized controlled trails (RCT) on dietary and physical activity interventions during pregnancy were considered.The quality of RCTs was appraised and data were extracted by 3 reviewers independently.Meta-analysis were conducted by RevMan 5.2 software.Results In total,eleven RCTs were included in this review.Meta-analysis revealed that dietary and physical activity intervention significantly reduced incidence of cesarean section and macrosomia;However,there were no statistically significant differences in the total gestational weight gain.Conclusions Interventions based on dietary and physical activity during pregnancy appears effective in reducing incidence of cesarean section and macrosomia.However,there are many limitation of the Meta analysis,therefore more multi-center,large sample with high quality RCTs are required for future verification.

One hundred elderly patients with hyperthyroidism were enrolled in a paired design study.The outcome of ~(131)Ⅰand antithyroid drug(ATD)treatments was examined after 2 years.The results showed that ~(131)Ⅰcould be recognized as the safer,more convenient and effective treatment than ATD for the elderly patients with hyperthyroidism.

Objective To investigate differences between Han and Uyghur children in dyslexia prevalence and potential environmental risk factors as well as to provide diagnosis and treatment evidence for dyslexia children . Methods We used cluster sampling to recruit 2 854 students in grades 3~6 from five Uyghur -Chinese bilingual primary schools in Xinjiang province .The children with dyslexia were selected step by step according to the defini‐tion of ICD-10 and DSM -IV .The children with DD and children without DD were selected and compared by 1∶1 of the same class ,ages and genders .Then single factor analysis and logistic regression analysis were used to as‐sess children'environmental risk factors .Results In total ,2 438 effective quostionnaires have been got .The difference between Han (3 .89% ) and Uyghur (7 .05% ) dyslexia prevalence was statistically significant .The factor analysis revealed that educational grades ,family income ,father's and mother's occupations ,and their education levels as well as some home literacy environmental factors were significantly different for the two groups of children with dyslexia (P<0 .05) .Conclusion The prevalence of dyslexia was high in both groups ,and especially for Uyghur children . Some environmental factors may be responsible for the differences noted ,especially for the occupation of mother .

The paper analyzes proposing and development of the concept of information literacy of clinical nurses and its relations with evidence-based nursing, nursing scientific research and clinical nursing, summarizes current situation and main opinions on influ-encing factors of the study, summarizes the methods and strategies to enhance information literacy of the clinical nurses, and tells the main direction and key points of the study on information literacy of clinical nurses.

Objective To investigate the gait differences among patients with Alzheimer's disease (AD) and mild cognitive impairment(AD-MCI) and the person with normal cognitive function,and analyze the reasons for the abnormal gait.Methods Eighty patients were included and divided into 3 groups according to the cognitive status:noncognitive impairment (NCI group,n =30),patients with mild cognitive impairment (AD-MCI group,n =29),Alzheimer's disease (AD group,n =21).The mini-mental state examination (MMSE),the Montreal Cognitive Assessment (MoCA),Addenbrooke's Cognitive Examination (ACE-R),the connection test (TMT-A),Digit Span Test(DST),activities of daily living questionnaire(ADL) and associated gait and balance scale (5 times sit to stand test (FTSTT),3 m walking test (TUG),Berg balance scale) were used to evaluate all research objects in each group.Results There were significant differences in NCI group compared with AD-MCI group and AD group in terms of FTSTT,TUG,Berg balance Scale and leg speed((9.59±2.39) s vs.(13.71±4.65) s vs.(14.15±4.20) s,(7.70±1.58) s vs.(11.13±3.02) s vs.(11.35±4.43) s,(54.20±1.56) points vs.(48.17±4.93) points vs.(48.10±5.46) points,(82.12±22.79) cm/s vs.(57.49± 14.89) cm/s vs.(57.70±14.68) cm/s;P＜0.05).There were significant differences in NCI group compared with AD-MCI group and AD group in terms of MMSE,MoCA,ACE-R,TMT-A,DST((28.67±1.27) points vs.(26.76±2.59) points vs.(21.86±5.29) points,(26.03±2.58) points vs.(22.39±5.05) points vs.(16.90±5.05) points,(85.80±5.90) points vs.(78.03±7.58) points vs.(60.95± 13.99) points,(12.66±5.36) s vs.(18.99 ± 11.46) s vs.(30.49±26.98)s,(18.60±4.64) points vs.(15.94±4.76) points vs.(12.86±5.23) points;P ＜0.05).Conclusion Gait disorder might be an early sign for cognitive impairment.

Objective To analyze the features of normal high-frequency ultrasonography of tarsal tunnel. Methods Forty volunteers (20 males and 20 females) were examined with high-frequency ultrasound (12 MHz). The tendons,nerve and blood vessels in tarsal tunnel were observed from short-axis and long-axis views dynamically. The areas of tarsal tunnel and posterior tibial nerve were measured and com-pared between the males and females. Results High-frequency ultrasonography depicted the anatomical structure of tarsal tunnel,and the tendons,nerve and blood vessels presented different sonographic features that were easy to differentiate. The area of tarsal tunnel: male (7.61 ±1.00) cm2,female (6. 61 ± 1. 07) cm2 (P <0. 01). The area of posterior tibial nerve: male (9. 59 ± 0. 75) mm2,female (8.91 ±0.74) mm2(P<0.01). Conclusion High-frequency ultrasonography can clearly show and accurately measure the tarsal tunnel structure. To be familiar with the normal ultrasonographic anatomy of tarsal tunnel will help to improve the efficacy of ultrasound diagnosis of tarsal tunnel abnormalities.

Objective To evaluate the predictive value of plasma levels of soluble vascular endothelial growth factor receptor 1(VEGFR-1,also known as sFlt-1) in second-trimester for preeclampsia.Methods One hundred and forty-six pregnant women with normal blood pressure previously were prospectively included in the study.Peripheral venous blood samples were obtained between 20 and 26 gestational weeks.Plasma levels of sFh-1 were measured by an enzyme-linked immunoassay.Results (1) Among 146 previously normotensive women,12 developed preeclampsia (preeclampsia group), 134 remained normal pregnant till the end (normal group).(2) The plasma levels of sFh-1 in preeclampsia group [(4135?699)ng/L] was significantly higher than that in normal group[(1490?1033)ng/L](P

Background and purpose:With the recognition of prognostic factors and application of surgical- pathological staging,the treatment strategy of endometrial cancer has greatly changed.In this study,we investigated the treatment strategy,survival rate and prognostic factors of endometrial cancer.Methods:Five hundred and fifty-nine patients of endometrial cancer underwent primary surgical treatment from January 1996 to December 2006 in Cancer Hospital,Fudan University.The clinicopathologic parameters and prognosis were analyzed retrospectively.Results: Patients were followed up with the median period 36 months,25 cases experienced local relapse,24 cases were found to have distant metastases.The 3-year overall survival(OS)was 88.7%,3-year and 5-year disease free survival(DFS) was 82.7% and 80.9%.The 3-year overall survival(OS)were 95.5% in stageⅠ,95.3% in stageⅡ,75.9% in stageⅢand 32.4% in stageⅣrespectively(P
