目的探讨梅毒感染孕产妇所生围产儿死亡情况及主要影响因素,为降低湖北省梅毒感染孕产妇所生围产儿死亡水平和消除梅毒母婴传播提供参考依据。方法收集2012年1月1日至2021年12月31日全国预防梅毒母婴传播管理信息系统中湖北地区报告的已分娩的梅毒感染孕产妇相关流行病学调查资料,采用趋势性χ^(2)检验和Logistic回归模型,分析梅毒感染孕产妇所生围产儿死亡情况及其影响因素。结果2012至2021年,湖北省梅毒感染孕产妇所生围产儿死亡率从39.11‰(7/179)下降至5.57‰(3/539),呈下降趋势(χ^(2)_(趋势)=9.95,P=0.002),梅毒感染孕产妇所生围产儿死亡率高于全人群围产儿死亡率。多因素分析结果显示,妊娠末次非梅血清学滴度≥1∶8(OR=5.58,95%CI:2.02~15.36)、妊娠末次非梅血清学滴度不详(OR=4.52,95%CI:1.70~12.02)、早产或低出生体质量(OR=7.21,95%CI:4.72~11.03)、新生儿窒息(OR=16.82,95%CI:8.10~34.93)、出生缺陷(OR=11.52,95%CI:5.09~26.10)均是梅毒感染孕产妇所生围产儿死亡的危险因素(P<0.05),接受治疗(OR=0.58,95%CI:0.37~0.91)是梅毒感染孕产妇所生围产儿死亡的保护因素。结论湖北省梅毒感染孕产妇所生围产儿死亡率呈逐年下降的趋势,早产/低出生体质量是梅毒感染孕产妇死亡的首要原因,重视开展科普宣教,早期检测规范治疗、积极降低非梅血清学滴度和加强新生儿保健服务质量是降低围产儿死亡发生风险的重要手段。

BACKGROUND： The traditional Chinese medicine acrous gramimeus is the dry rhizome of Acrous gramimeus Soland, a kind of Araceae familial perennial herb, which has a sedation action, anticonvulsant and antiepileptic effect. Its effective component has not been known yet, and α-asarone, the major component of the volatile oil extracted from acrous gramineus, has been supposed to play a necessary role in it. OBJECTIVE： To explore the effects of acrous gramimeu and α-asarone on the reactivity and convulsive threshold to electric stimulation in immature rats, furthermore, attempt to definitize the anticonvulsant effect of α-asarone. DESIGN： A randomized controlled study.SETTINGS： Department of Pediatrics, First Hospital of Jilin University; Department of Histology and Embryology, School of Basic Medical Sciences of Jilin University; Department of Neurology, First Clinical Hospital affiliated to Harbin Medical University; Department of Internal Medicine, Children＇s Hospital of Changchun City. MATERIALS ： Seventy 3-week immature Wistar rats （either males or females） of 34-40 g were used. Acrous gramimeu （1 g/bag, the content of α-oasarone was 0.046 26%-0.070 16%） with the batch number of 0307113 was provided by Tianjiang Medicine Company Limited, Jiangyin City. α-asarone tablet （60 mg per tablet） with the batch number of 030219 was provided by Tianwei Pharmaceutical Factory, Shenyang City. α-asarone injectable preparation （2 mL per piece） with the batch number of 030105 was provided by Shuanghe Medicine Limited Company, Beijing City. METHODS ： The experiments were carried out in the Neurological Laboratory of the First Hospital of Jilin University between August and October in 2004.① The 70 rats were randomly divided into intragastric subset and intraperitoneal subset. The intragastric subset included four groups of control, phenobarbital sodium, acrous gramimeu and α-asarone; the intraperitoneal subset included three groups of control, phenobarbital sodium and α-

The biogenic silica (BSi) ,total organic carbon (TOC) ,total nitrogen (TN) and grain size were analyzed with a gravity core (3250-6) collected from the mud area in the north East China *** average deposition rate of the upper core was about 0.078cm yr1based on the results of *** mean grain size increased with depth in *** frequency distribution of grain size showed that two marked changes of deposition environment occurred at 30 cm and 50 cm depths (about 1550 AD and 1300 AD,respectively) .The variations of BSi and TOC indicated two distinct major periods of primary productivity over the past 800 years:a stage of low primary productivity corresponding to weak upwelling and low nutrient input below 30 cm depth (about 1200-1550 AD) ,and a stage of high primary productivity with strong currents and upwelling above 30 cm depth (about 1550-1950 AD) .The stage with high primary productive appeared to be due to the northward-expanded muddy area caused by strong Asian Winter Monsoon and enhanced Yellow Sea Warm Current in *** conclusion,the BSi and TOC in the muddy sediments,the symbols of marine primary productivity,can be then used to investigate the evolution history of currents and relative climate change in the offshore areas.
