OBJECTIVE: To assess the effectiveness and safety of Xianling Gubao(XLGB) Capsule in the treatment of osteoporotic fracture(OF). METHODS: Published articles from eight Chinese and English databases were searched from inception to August 2017. Clinical trials were selected according to inclusion criteria and exclusion criteria. Risk evaluation tool was used to assess the quality of studies. Data was extracted and meta-analysis was performed by RevMan5.3 software. RESULTS: A total of 229 articles were searched, and 27 were included for study with 2292 samples,including 1152 cases in the experiment group and 1140 cases in the control group. For patients with four limbs OF,XLGB Capsule combined with manipulation reposition with plaster external fixation can shorten healing time of fracture[MD=–0.77, 95% CI(–1.25, –0.30)], increase bone mineral density(BMD) [MD=0.17, 95% CI(0.10, 0.25)], blood calcium content [MD=0.52, 95% CI(0.38, 0.64)], phosphorous content in serum [MD=0.28, 95% CI(0.21, 0.35)], and alkaline phosphatase content [SMD=–5.24, 95% CI(–3.45, –2.42)]. In the treatment of spine OF, XLGB Capsule had no significant effects on reducing re-fracture rate of non-surgical vertebral body, but it could postpone the interval time of refracture of non-surgical vertebral bodies [RR=0.71, 95% CI(0.23, 2.18)]. Combined treatment with XLGB Capsule could improve clinical effective rate [RR=1.17, 95% CI(1.11, 1.23)]. Both alone and combined application of XLGB Capsule could increase BMD and calcitonin content of patients with spine OF. Combined application of calcium or medicine that regulating calcium metabolism was faster in reducing Cobb angle of centrum kyphosis than application alone [MD=–2.68,95% CI(–3.72, –2.12)]. Alone or combined application showed no significant effects on osteoporotic pain. The adverse reactions reported in the study were mainly the digestive system damage. CONCLUSIONS: XLGB Capsule alone or combine with other western medicine had better efficacy

目标多尺度性质、高层语义信息不足等造成现有算法很难在目标边界取得非常准确的分类精度。为此,提出了一种基于多层次特征融合的语义分割算法。在解码阶段,设计了三个特征提取分支,分别为空间细节分支、语义补充分支和上下文信息分支。空间细节分支采用浅层较高分辨率特征图来生成最终分割图,主要用于保留大量空间细节信息。语义补充分支用于增加更多的高层语义抽象信息。上下文信息分支主要负责提取多尺度全局信息。在语义补充分支中,设计了一种特征融合指导模块(FFGM),建模不同特征图之间像素的对应关系,从而有效地融合不同层次的特征。在空间细节分支中,提出一种自增强特征模块(SEM),对低层次特征进行精调细化,旨在得到清晰的目标边界。在上下文信息分支中,采用金字塔池化模块(PPM)获得多尺度上下文信息,解决目标多尺度性带来的像素错分问题。最后,采用注意力机制融合三个分支提取的特征图,从而强化重要特征,抑制非显著特征。在主流的语义分割数据集PASCAL VOC2012与Cityscapes上,该网络模型获得了81.12%的平均交并比和74.56%的平均交并比,明显优于实验比较算法。

Vehicular emissions in China in 2006 and 2010 were calculated at a high spatial resolution based on the data released by the National Bureau of Statistics, by taking the emission standards into consideration. China＇s vehicular emissions of carbon monoxide （CO）, nitrogen oxides （NOx）, volatile organic compounds （VOCs）, ammonia （NH3）, fine particulate matters （PM2.5）, inhalable particulate matters （PMlo）, black carbon （BC）, and organic carbon （OC） were 30,113.9, 4593.7, 6838.0, 20.9, 400.2, 430.5,285.6, and 105.1 Gg, respectively, in 2006 and 34,175.2, 5167.5, 7029.4, 74.0, 386.4, 417.1, 270.9, and 106.2 Gg, respectively, in 2010. CO, VOCs, and NH3 emissions were mainly from motorcycles and light-duty gasoline vehicles, whereas NOx, PMzs, PMlo, and BC emissions were mainly from rural vehicles and heavy- duty diesel trucks. OC emissions were mainly from motorcycles and heavy-duty diesel trucks. Vehicles of pre-China I （vehicular emission standard of China before phase I） and China I （vehicular emission standard of China in phase I） were the primary contributors to all of the pollutant emissions except NH3, which was mainly from China III and China IV gasoline vehicles. The total emissions of all the pollutants except NH3 changed little from 2006 to 2010. This finding can be attributed to the implementation of strict emission standards and to improvements in oil quality.
