糖尿病患者饮食的自我调控单因素回归分析

目的 研究糖尿病患者饮食和自我调控的关系。方法 采用问卷法和访谈法。结果 经过对与饮食相关的诸因素进行Logistic单因素分析,每次喝酒量的多少,家人对饮食疗法执行的支持情况,性别等三项指标,其OR值均大于1,是正调控因素。说明自我调控越强喝酒越少;家人越支持饮食疗法执行情况越好;男性的自我调控力在执行饮食疗法时比女性高,测血糖的时间,OR值小于1,自我调控力越高的人测血糖越定时。结论 饮食疗法的控制和自我调控力并非正相关。     

Hand grip strength as a predictor of recovery from low back pain in the pregnant women-a prospective study

BackgroundLow back pain (LBP) is a common musculoskeletal problem during pregnancy with an estimated prevalence ranging from 30% to 78%. The symptoms usually disappear gradually after delivery, but some women may have persistent problems even later in their lives. The definite mechanism behind LBP during pregnancy remains unknown. Therefore, the purpose of this study was to investigate whether hand grip strength (HGS), which is a straightforward and reliable indicator of overall muscle strength, is associated with unrecovered LBP after delivery.Methods257 pregnant women who registered at obstetrics units in two tertiary hospitals from January 2016 to June 2017 and meanwhile suffered the LBP during pregnancy were included. They were grouped based on whether they recovered from LBP after delivery (recovery was de?ned as a pain rating of ≤3). The variables such as age, HGS, and education level were recorded and examined for the risk analysis of unrecovered LBP. Also, the Pearson correlation between HGS levels and pain intensities was investigated.ResultsLBP without recovery at two years after delivery was reported among 22.7% of the subjects. Women with increasing age, low HGS (<25 kg), LBP in a previous pregnancy, back pain, sick leave, and a large amount of physical demand (all p < 0.05), were more likely to report LBP without recovery. Besides, there was a significant correlation between HGS values and the intensities of LBP (r = ?0.525; p = 0.003).ConclusionsLow HGS has the highest OR value (adjusted OR = 9.12, P < 0.001) among these factors. The present findings may be used to design and encourage a specific stabilization exercise regime to build well stability of the lumbar spinal column and thus alleviating the LBP.

不同波段红外线对小鼠胚胎发育作用的实验研究

目的:研究不同波段红外线对小鼠胚胎的作用。方法:采用不同波段的红外线对正常孕鼠及环磷酰胺(CP)致毒孕鼠的照射,观察了受孕母鼠的体重变化,活胎率、死胎率、吸收胎率以及胎鼠的身长、尾长、体重等指标。结果:单纯红外线照射各组孕鼠的体重、胎鼠的体重、身长、尾长都有增加。其中中波红外线组与正常对照组相比有显著性差异(P<0.01)。阳性对照组(CP组)与正常对照组比较活胎率、死胎率、吸收胎率、胎鼠的体重、身长、尾长均有显著性的差异(P<0.01),CP可明显抑制胎鼠的发育及降低胎鼠的活胎率。红外线+CP各组与阳性对照组比较,活胎率、吸收胎率、死胎率、胎鼠的体重、身长、尾长均有显著性差异。结论:红外线特别是中波红外线能促进胚胎的生长并对CP引起的胚胎发育障碍有一定的缓解作用。

Vaxvec: The first web-based recombinant vaccine vector database and its data analysis

A recombinant vector vaccine uses an attenuated virus, bacterium, or parasite as the carrier to express a heterologous antigen(s). Many recombinant vaccine vectors and related vaccines have been developed and extensively investigated. To compare and better understand recombinant vectors and vaccines, we have generated Vaxvec (http://www.violinet.org/vaxvec), the first web-based database that stores various recombinant vaccine vectors and those experimentally verified vaccines that use these vectors. Vaxvec has now included 59 vaccine vectors that have been used in 196 recombinant vector vaccines against 66 pathogens and cancers. These vectors are classified to 41 viral vectors, 15 bacterial vectors, 1 parasitic vector, and 1 fungal vector. The most commonly used viral vaccine vectors are double-stranded DNA viruses, including herpesviruses, adenoviruses, and poxviruses. For example, Vaxvec includes 63 poxvirus-based recombinant vaccines for over 20 pathogens and cancers. Vaxvec collects 30 recombinant vector influenza vaccines that use 17 recombinant vectors and were experimentally tested in 7 animal models. In addition, over 60 protective antigens used in recombinant vector vaccines are annotated and analyzed. User-friendly web-interfaces are available for querying various data in Vaxvec. To support data exchange, the information of vaccine vectors, vaccines, and related information is stored in the Vaccine Ontology (VO). Vaxvec is a timely and vital source of vaccine vector database and facilitates efficient vaccine vector research and development.
