Medications for common cold are used routinely in daily life， and most of these are compounded to be more effective for people suffering from common cold. The composition and quality of the coating， a common component of tablets， have been of great concern. In this paper， laser-induced breakdown spectroscopy (liBS)， with advantages of rapid， real-time， and in-situ analysis， was used for surface analysis of tablets with and without coating film for common cold. Firstly， the spectra of compound paracetamol and amantadine hydrochloride tablets (CPAHT) and compound diclofenac sodium and chlorphenamine maleate tablets (CDSCMT)， without and with coating film， respectively， were analyzed. Secondly， two kinds of tablets were investigated in-situ at depth to analyze the changes of atomic and molecular spectral line intensities under different number of laser pulses and verified using liBS imaging method. Finally， the Ca and Ti elements in CDSCMT were analyzed by calibration free liBS (CF-liBS) to further verify the elemental content differences at different depth in the tablets with coating film. These results indicate that the liBS technology can be used in fast， in-situ， depth， and multi-element detection for cold medication tablets.

目的对卵形疟原虫(Plasmodium ovale)curtisi亚种和wallikeri亚种编码的细胞色素b(cytochrome b,Cytb),细胞色素c氧化酶Ⅰ(cytochrome c oxidaseⅠ,CoxⅠ)和乳酸脱氢酶(lactate dehydrogenase,LDH)基因的单核苷酸多态性进行分析。方法选择浙江省疟疾诊断参比实验室2011-2014年确诊的卵形疟原虫感染患者血样,提取卵形疟原虫DNA,巢式PCR扩增卵形疟原虫Cytb、CoxⅠ和LDH基因的部分片段,对扩增产物进行双向测序。测序序列经校对、拼接后,应用MEGA软件对测序序列和相应的氨基酸序列进行比对,分析单核苷酸多态性位点以及氨基酸突变位点。结果 19例卵形疟原虫感染者(其中curtisi亚种11例,wallikeri亚种8例)均为赴非洲返国人员。PCR扩增Cytb、CoxⅠ和LDH基因的产物长度分别为735、1 323和355 bp。curtisi和wallikeri两个亚种在Cytb、CoxⅠ和LDH基因分别发现10、13、13个单核苷酸二态性位点,且大多数的二态性位点属于同义突变。此外,两个亚种内部也存在核苷酸多态性,同时发现1例血样的CoxⅠ基因存在693个碱基的缺失。结论对卵形疟患者血样的Cytb、CoxⅠ和LDH基因进行了单核苷酸多态性分析,丰富了卵形疟原虫基因多态性信息。

A lightweight road-assistant detection algorithm， EBD-YOLO， based on YOLOv5s is proposed to address the problems of high model complexity， computation cost， and difficulty in deployment on resource-limited embedded terminals in existing assisted driving detection algorithms. First， lightweight Transformer model EfficientViT was used as the backbone feature extraction network of YOLOv5s model to reduce network parameters and calculation costs. Secondly， a Focal-GIoU Loss function is proposed for bounding box regression to accelerate model convergence and reduce loss. Thirdly， the feature pyramid structure is improved to a weighted bi-directional feature pyramid network (BiFPN) to enhance localization and semantic features. Then， a dynamic head framework is added to unify the attention mechanism with the object detection head to improve its performance. Finally， a Soft-CIoU＿NMS algorithm is proposed in the post-processing stage to enhance occluded targets' localization and detection ability and reduce the missed detection rate. We conducted experiments on the KITTI and BDD100K datasets for autonomous driving， and the results showed that the EBD-YOLO model reduced in size by 38.4% and 37.2%， respectively. In comparison， the computational cost was reduced by 48.1%. As measured by mAP@0.5， the detection accuracy improved by 0.5% and 5.8%， respectively， and mAP@0.5:0.95 improved by 2.8% and 7%， respectively. These improvements satisfied the requirements for deployment on embedded terminals in cars.
