OBJECTIVE: To evaluate and summarise the evidence from published Meta-analyses/systematic reviews(MAs/SRs) of Traditional Chinese Medicine(TCM) in the treatment of recurrent respiratory tract infections(RRTIs) and to provide a scientific basis for the clinical treatment of RRTIs with TCM. METHODS: Studies were retrieved from Chinese and English databases including the China National Knowledge Infrastructure, Wanfang database, China Science and Technology Journal Database, SinoM ed, PubM ed, Web of Science, the Cochrane Library and EMbase from their establishment date to March 2023. Involved studies were screened, extracted, and evaluated for quality by two researchers independently. The a measurement tool to assess systematic reviews(AMSTAR) 2 scale was used for methodological quality evaluation, as well as the preferred reporting items for systematic reviews and Meta-analyses(PRISMA) 2020 statement for report quality evaluation, the risk of bias in systematic reviews(ROBIS) tool for risk of bias, and the grading of recommendations, assessment, development and evaluation(GRADE) quality assessment tool for evidence quality. RESULTS: Twenty MAs/SRs studies were included, including analyses of 274 original studies involving 38 335 patients with RRTIs. The AMSTAR 2 scale evaluation results showed that 19 studies were of very low quality and one of moderate quality. The ROBIS evaluation results showed that 11 MAs/SRs were at high risk and nine at low risk of bias. The PRISMA 2020 report quality showed the included studies had scores between 23.5 and 35.5, among them one with high quality, 17 with moderate quality and two with low quality. The GRADE system results showed that among 126 outcome indicators, only 17 had moderate quality of evidence, 27 had low quality, 82 had very low quality, and none had high quality. CONCLUSIONS: The MAs/SRs methodological quality of using TCM for treatment RRTIs is generally poor, the quality of reports as well as of evidence is generall

目的对已报道的围绝经期综合征(perimenopausal syndrome,PS)动物模型制备方法进行综合分析,比较模型制备各要素和检测指标的优缺点,为优化相关动物模型并规范其在新药疗效评价中的运用提供有益参考。方法采用文献研究方法,以“围绝经期综合征”和“perimenopausal syndrome”等为主题词,在中国知网、万方数据、PubMed等数据库中检索2016年1月—2023年2月发表的与PS动物模型制备相关的文献,按照纳入标准和排除标准筛选出符合PS动物模型制备的实验文献,梳理文献中详细记载的实验动物品系、造模方法、给药时长、阳性药物、检测指标等相关信息。将上述信息统一进行标准化处理后,利用Excel2010表格建立PS动物模型数据库,系统归纳总结模型制备要素和评价指标,并用Excel2010软件进行统计学处理和分析。结果共筛选出247篇文献。制备PS动物模型常选用SD大鼠(164次,65.86%)和Wistar大鼠(35次,14.06%)。造模方法常选择双侧卵巢摘除法(139次,53.87%)和自然老化法(43次,16.80%)。用于建模的大鼠年龄从7周龄~18月龄不等,其中以3月龄大鼠(22次,21.78%)最常用。关于检测指标,大多采用血清生化、阴道脱落细胞涂片、组织形态学、一般情况观察、行为学观察以及脏器组织蛋白免疫印迹等多指标进行综合评价。检验模型是否成功制备常选用西医评价指标,西医常用阴道脱落细胞涂片方法判定动情周期(125次,85.04%),待实验者观察到实验动物动情周期紊乱或不规则即可认为模型制备成功;同时也有部分文献通过检测发现血清雌二醇含量明显降低来判定造模成功(5次,3.04%)。中医证型评价常采用中西医评价指标相结合的方法进行综合评价,实验者通过阴道脱落细胞涂片辅以一般情况观察判断中医证型(3次,2.04%)。结论目前已有的PS动物模型制备方法较多,但相关研究在动物种属选择、动物年龄、造模成功标准、中医证型评价等方面仍存在较大差异。

目的探究盆腔炎性疾病(pelvic inflammatory disease,PID)动物模型的造模要素和评价指标,为改进PID动物模型的造模方法、完善PID动物模型的合理应用提供参考依据。方法以“盆腔炎”并且“动物模型”或“鼠”或“豚鼠”或“兔”或“犬”或“猪”为主题词,在中国知网数据库、万方数据库和PubMed中检索2013—2023年发表的PID动物模型相关文献,对文献中记载的实验动物种类、造模方法、造模周期、检测指标、阳性对照用药和给药时间等内容进行整理归纳,建立数据库并进行统计分析。结果检索筛选出214篇符合纳入标准的PID动物模型文献。其中,模型动物种类选用最多的是SD大鼠,其次为Wistar大鼠;最常用的造模方式是机械损伤联合细菌感染法,其次是苯酚胶浆法;急性盆腔炎(acute pelvic inflammatory disease,APID)和慢性盆腔炎(chronic pelvic inflammatory disease,CPID)/盆腔炎性疾病后遗症(sequelae of pelvic inflammatory disease,SPID)动物造模周期频次最高的是8~14 d,其他不明确分期PID造模周期频数最高的是7 d;高频检测指标包括用苏木精-伊红染色法观察组织病理、酶联免疫吸附法检测血清相关指标、肉眼观察组织外观变化、免疫组化法检测子宫组织中相关蛋白表达和病理评分等;阳性对照药物应用频次最高的是妇科千金片,其次是金刚藤胶囊;APID给药时间频数最高的是7 d,CPID/SPID动物模型给药时间频次最多的是15~21 d。结论目前SD大鼠和Wistar大鼠是制备PID模型常用的实验动物,采用机械损伤加混合细菌感染双重造模法与临床发病机制吻合度较高,可建立术后宫腔感染引起的PID模型;根据研究目的不同,可选取不同的阳性对照药物和检测指标进行整体评价。现有的PID动物模型研究大都以西医诊断为标准,对中医症候动物模型的研究较少,需结合中医理论病因病机,构建更符合中医临床病证的PID动物模型。

为了避免利用2D图像提取特征点并进行三维重建的烦琐,同时满足芯片引脚3D测量指标的高精度要求,采用点云处理技术,提出一种基于法向量差异的点云水平校准方法,将该方法与最小外包围盒算法相结合来剔除芯片内部引脚点云。对剩余点云进行聚类分割后,利用采样一致性算法对芯片各外部引脚、上下表面进行平面方程参数拟合并求解各引脚区域的中点。通过以上获取的数据计算芯片高度、引脚栈高以及引脚翘起度。最后,通过试验验证了所述芯片测量方案的有效性。

为提高复杂环境下无人特种车辆安全性、自主性及作业能力,面向在崎岖地形下无人特种车辆应用需求,提出一种基于地形特征时频变换的速度自适应控制方法。通过度量地形特征崎岖度、建立崎岖度和车速数学模型,实现无人特种车辆在崎岖地形的自主、自适应车速规划。针对崎岖地形和坡度引起的点云数据失真问题,融合惯性测量单元传感器数据对点云进行补偿,获得了车辆前方地形的精准点云数据;针对可视距离与跟踪精度冲突问题,不同于传统横向曲率计算方式,采用以线到面的方式,将激光雷达纵向剖面点云数据进行时频变换后,在频域内选取次频区域的积分面积作为崎岖度量化值,实现对不同地形下的崎岖度量化;此外,基于上述获得的崎岖度,采用迭代搜索的方式建立速度与崎岖度数学模型,并采用滑动窗口的方式更新崎岖度,实现车速到崎岖度之间的连续映射。以可控震源野外勘探特种车为研究对象,采用上述方法在实际野外地形环境中进行多次实验。实验结果表明,所提出的方法在崎岖地形具有良好的安全性、自主性,可以识别地形和自适应控制车速。
