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:总结儿童重症肺炎支原体肺炎所致塑型性支气管炎的临床特点,寻找发生塑型性支气管炎的危险因素,为判断预后和综合制定治疗方案提供参考。方法:回顾性分析2017年1月至2019年12月中国医科大学附属盛京医院小儿呼吸内科收治的急性期行支气管镜检查的重症肺炎支原体肺炎患儿的临床资料(146例),按照是否为塑型性支气管炎,分为塑型性支气管炎组(68例)和非塑型性支气管炎组(78例),并收集患儿性别、年龄、实验室检查指标、影像学特征和治疗情况,将有临床意义及统计学意义的单因素进行多因素Logistic回归分析。结果:两组患儿性别、年龄、热程、白细胞数、C-反应蛋白值、白细胞介素-6值比较差异均无统计学意义(均P>0.05)。塑型性支气管炎组中性粒细胞百分比、丙氨酸转氨酶、天冬氨酸转移酶、乳酸脱氢酶、D-二聚体、胸腔积液例数、住院时间、支气管镜检查次数均高于非塑型性支气管炎组,右肺上叶实变例数少于非塑型性支气管炎组,差异均有统计学意义(P<0.05)。多因素Logistic回归分析显示,胸腔积液(OR=4.898,95%CI 2.195-10.926)、乳酸脱氢酶(OR=1.051,95%CI 1.003-1.101)是儿童重症肺炎支原体肺炎发生塑型性支气管炎的独立预测指标。结论:重症肺炎支原体肺炎患儿,如肺CT提示非右肺上叶均一致密实变影且合并胸腔积液,乳酸脱氢酶明显增高,应注意发生塑型性支气管炎的可能,需及时完善纤维支气管镜检查,可能缩短病程,减少并发症的发生。

地方主导型产业政策加深了“行政区经济”的市场壁垒和地方保护,严重阻碍全国统一大市场建设。当前迫切需要以中央主导型产业政策推进全国统一大市场建设。重点方向是通过缓解要素市场和中间品市场交易壁垒来降低生产端的市场交易成本,通过缓解商品市场分割来降低消费端的市场交易成本。中央主导型产业政策推进全国统一大市场建设,具体在于促进要素自由流动和公平竞争,消除地方政府使用产业政策搞“自我小循环”的各种因素;充分发挥中央主导型产业政策的“统一”作用,降低地方主导型产业政策的“分割”性;积极推动地方政府之间的沟通交流,将区域协调发展战略的实施作为开展全国统一大市场建设的推进器。
