The pea leafminer (Liriomyza huidobrensis) is a notorious pest of vegetables and ornamental plants worldwide. Despite a large number of studies on its biology and ecology, the courtship behavior and sexual communication of this species remain unclear. Here, we studied vibrational communication in the sexual interaction of the pea leafminer. On host plant leaves, females and males behaviorally displayed the bobbing-quivering alternation, which finally led to copulation. Moreover, records of laser vibrometry revealed threesignal duets underlying the behavioral alternation. Sexually mature males spontaneously emitted calls (MCs) to initiate the duets. The females rapidly responded to MCs by emitting replies (FRs) that are longer in duration. The FRs further triggered male replies (MRs) in their search for potential partners. Leafminer-produced vibrational signals convey efficient information to partners and generate pair formation on stretched substrates, such as plant leaves and nylon mesh, but cannot elicit responses on dense substrates, such as glass and plastic. Vibrational playbacks of both MCs and FRs can elicit replies in females and males, respectively. This study completely characterizes substrate-borne vibrational duets in a dipteran insect. The discovery of vibrational sex signals in the pea leafminer provides new insights for the development of novel approaches to control the pest and its relative species.

Patients with complete spinal cord injury retain the potential for volitional muscle activity in muscles located below the spinal injury ***,because of prolonged inactivity,initial attempts to activate these muscles may not effectively engage any of the remaining neurons in the descending pathway.A previous study unexpectedly found that a brief clinical round of passive activity significantly increased volitional muscle activation,as measured by surface *** this study,we further explored the effect of passive activity on surface electromyographic signals during volitional control tasks among individuals with complete spinal cord *** patients with chronic complete thoracic spinal cord injury were *** electromyography data from eight major leg muscles were acquired and compared before and after the passive activity *** results indicated that the passive activity led to an increased number of activated volitional muscles and an increased frequency of *** the cumulative root mean square of surface electromyography amplitude for volitional control of movement showed a slight increase after passive activity,the difference was not statistically *** findings suggest that brief passive activity may enhance the ability to initiate volitional muscle activity during surface electromyography tasks and underscore the potential of passive activity for improving residual motor control among patients with motor complete spinal cord injury.

目的研究阴道毛滴虫（Trichomonas vaginalisvirus）对甲硝唑的耐药性，探索共生人型支原体对其耐药性的影响。方法由医院提供阴道毛滴虫样品，对其进行体外培养，达到纯培养后提取虫株核酸，进行扩增及测序；制备浓度梯度板，测定甲硝唑对阴道毛滴虫的最小致死浓度（minimum lethallon centration，MLC），并将人型支原体进行序列分析和清除后再测定DNA及MLC，并作前后比较。结果甲硝唑对34株阴道毛滴虫MLC范围为1～300／μg／ml，其中敏感性较高的共有21株，9株敏感性略低，4株敏感性低；在人型支原体共生与甲硝唑MLC关系测定中，12株扩增出特异性产物（长度大小约为530bp），阳性率为35．3％。DNA检测阳性的12株阴道毛滴虫中，甲硝唑MLC在1～25μg／ml、50～70μg／ml和100～300μg／ml范围内的虫株共生率分别为14．3％、66．7％和75．0％。当MLC在300μg／ml时，有2个虫株呈现人型支原体共生现象，显示人型支原体共生状态与甲硝唑MLC之间存在一定的关联性；清除人型支原体后的甲硝唑MLC测定中，加入多西环素并对虫株进行传代培养。当传至3代后进行检测，12株阳性虫株中仅有7株未再检出人型支原体DNA，其中甲硝唑敏感株的4株MLC无变化，对甲硝唑耐药的3株MLC略有降低，但仍维持在较高水平。结论甲硝唑MLC不同的阴道毛滴虫虫株人型支原体的共生情况也不同。对甲硝唑耐药性越强的虫株人型支原体检出率越高，甲硝唑MLC为300μg／ml的虫株均查出人型支原体，表明阴道毛滴虫对甲硝唑的耐药性与人型支原体共生现象可能存在一定关系。

目的分析本院产妇发生产后感染的病原菌分布特点、感染因素及厚朴排气合剂辅助疗效。方法采集被诊断为产后感染的产妇的血液、尿液、腹水、切口分泌物等标本,采用全自动微生物鉴定仪鉴定病原菌。采用回顾性分析方法,调查参与研究的所有产妇病历资料,分析不同分娩方式对产后感染的影响及产后感染的相关因素。选取本次研究中200例未发生产后感染的剖宫产产妇,分为对照组与观察组,分析厚朴排气合剂对剖宫产术后肠胃功能恢复的辅助疗效。结果本次研究中,92例产妇发生产后感染,感染率为4.57%,其中55.43%为初产妇。67例出现妊娠并发症,主要为妊娠期糖尿病、妊娠高血压、胎膜早破。产后感染产妇的临床表现,主要为剖宫产伤口感染(27.17%)、急性阴道感染(22.83%)、急性外阴感染(15.22%)、急性宫颈感染(10.87%)。感染产妇主要分布于30~39岁(56.52%)。92例产后感染产妇采集标本92份,88份样本检出病原菌,检出率为95.65%。共培养出病原菌96株,80例为单一病原菌感染,8例为两种病原菌混合感染。96株病原菌中,51.04%为革兰阳性菌,以金黄色葡萄球菌(29.17%)居多;42.71%为革兰阴性菌,以大肠埃希菌(23.96%)居多;3.13%为真菌感染,3.13%为厌氧菌感染。参与本次研究的2015例产妇接受常规分娩为对照组,选取同期90例产妇参与医院开展的无保护性自然分娩为试验组,试验组产妇感染率为2.22%,对照组产妇感染率为4.57%,对照组感染率明显高于试验组。分析参与本次研究的产妇资料发现,产妇发生产后感染,与产妇年龄、体重指数、是否吸烟无关(P>0.05)。产后感染率与分娩次数、分娩时长、分娩方式、侵入性操作次数、是否严格消毒、是否并发其他基础疾病、是否进行人工宫腔操作有关(P<0.05)。对比接受不同治疗方式的对照组与观察组产妇的治疗指标发现,观察组产妇的首次肛门排气时间、首次肛门排便时间均短于对照组,术后72 h胃肠道相关并发症发生率低于对照组,差异有统计学意义(P<0.05)。结论本院产妇产后感染主要为剖宫产伤口感染,集中于30~39岁,以金黄色葡萄球菌与大肠埃希菌为主要病原菌。分娩次数多、分娩时间长、侵入性操作次数多等,容易引起产妇产后感染。通过厚朴排气合剂辅助治疗,可以缩短剖宫产后产妇的住院时间,降低产后感染的发生。
