Intrauterine infection is an important cause of some birth defects worldwide. The most common pathogens include rubella virus, cytomegaloviurs, ureaplasma urealyticum, toxoplasma, etc. General information about these pathogens in epidemiology, consequence of birth defects, and the possible mechanisms in the progress of birth defects, and the interventions to prevent or treat these pathogens?infections are described. The infections caused by rubella virus, cytomegaloviurs, ureaplasma urealyticum, toxoplasma, etc. are common, yet they are proved to be fatal during the pregnant period, especially during the first trimester. These infections may cause sterility, abortion, stillbirth, low birth weight, and affect multiple organs that may induce loss of hearing and vision, even fetal deformity and the long-term effects. These pathogens?infections may influence the microenvironment of placenta, including levels of enzymes and cytokines, and affect chondriosome that may induce the progress of birth defect. Early diagnosis of infections during pregnancy should be strengthened. There are still many things to be settled, such as the molecular mechanisms of birth defects, the effective vaccines to certain pathogens. Birth defect researches in terms of etiology and the development of applicable and sensitive pathogen detection technology and methods are imperative.

Background A multi-center large scale study is needed to confirm the efficacy and safety of domestic peritoneal dialysis （PD） solutions. Some researchers believe that 6 Lid is enough for adequate dialysis, but there is no multi-center prospective study on Chinese population to confirm this. In this study, we evaluated the efficacy and safety of domestic PD solution （Changfu） and its difference between 6 L and 8 L dosage. Methods Adult PD patients who had taken PD therapy for at least one month were selected and divided into four groups according to two dialysis solution brands and two dialysis dosages, i.e., 6 L dose with Changfu dialysis solution, 6 L dose with Baxter dialysis solution, 8 L dose with Changfu dialysis solution, and 8 L dose with Baxter dialysis solution. After 48 weeks, the changes of primary and secondary efficacy indices were compared between different types and different dosages. We also analyzed the changes of safety indices. Results Changes of Kt/V from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of creatinine clearance rate （Ccr）. Normalized protein catabolic rate （nPCR） from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of net ultrafiltration volume （nUF） and estimated glomerular filtration rate （eGFR）. Changes of nPCR from baseline to 48 weeks between 6 L and 8 L showed no statistical differences; so did those of nUF and eGFR. The decline of Kt/V from baseline to 48 weeks in 6 L group was more than that in 8 L group. Change of Ccr was similar. During the 48-week period, the mean Kt/V was above 1.7/w, and mean Ccr was above 50 L.1.73 m-2.w1. More adverse events were found in Changfu group before Changfu Corporation commenced technology optimization, and the statistical differences disappeared after that. Conclusions The domestic PD solution （Changfu） was proven to be as effective as Baxter dialysis solution. During 48- week period, a dosage o

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in june 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in june 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

Background： Over the years, the mechanical ventilation （MV） strategy has changed worldwide. The aim of the present study was to describe the ventilation practices, particularly lung-protective ventilation （LPV）, among brain-injured patients in China. Methods： This study was a multicenter, 1-day, cross-sectional study in 47 Intensive Care Units （ICUs） across China. Mechanically ventilated patients （18 years and older） with brain injury in a participating ICU during the time of the study, including traumatic brain injury, stroke, postoperation with intracranial tumor, hypoxic-ischemic encephalopathy, intracranial infection, and idiopathic epilepsy, were enrolled. Demographic data, primary diagnoses, indications for MV, MV modes and settings, and prognoses on the 60th day were collected. Multivariable logistic analysis was used to assess factors that might affect the use of LPV. Results： A total of 104 patients were enrolled in the present study, 87 （83.7%） of whom were identified with severe brain injury based on a Glasgow Coma Scale 〈8 points. Synchronized intermittent mandatory ventilation （SIMV） was the most frequent ventilator mode, accounting for 46.2% of the entire cohort. The median tidal volume was set to 8.0 ml/kg （interquartile range [IQR], 7.0-8.9 ml/kg） of the predicted body weight; 50 （48.1%） patients received LPV. The median positive end-expiratory pressure （PEEP） was set to 5 cmH20 （IQR, 5-5 cmH20）. No PEEP values were higher than 10 cmH20. Compared with partially mandatory ventilation, supportive and spontaneous ventilation practices were associated with LPV. There were no significant differences in mortality and MV duration between patients subjected to LPV and those were not. Conclusions： Among brain-injured patients in China, SIMV was the most frequent ventilation mode. Nearly one-half of the brain-injured patients received LPV. Patients under supportive and spontaneous ventilation were more likely to receive LPV.

目的了解鄂西南地区新生儿急性呼吸窘迫综合征(ARDS)的临床特点及转归。方法采用回顾性临床流行病学方法,根据新生儿ARDS蒙特勒诊断标准对2017年1~12月鄂西南地区17家二级或三级医院新生儿科/儿科收治的新生儿ARDS病例资料进行调查分析。结果所纳入的鄂西南地区17家医院2017年1年内共收治新生儿7150例,其中确诊新生儿ARDS 66例(0.92%),包括轻度23例(35%),中度28例(42%),重度15例(23%)。新生儿ARDS的主要原发疾病包括:围生期窒息(23例,35%)、肺炎(18例,27%)、败血症(12例,18%)、胎粪吸入综合征(10例,15%)。66例ARDS患儿中,产妇年龄≥35岁10例(15%),宫内窘迫30例(45%),1 min Apgar评分0~7分32例(49%),胎心监测异常24例(36%),羊水胎粪污染21例(32%)。脑室内出血是最常见的合并症(12例),其次为新生儿休克(9例)、动脉导管未闭(8例)。66例ARDS患儿在针对原发病治疗的基础上,均给予机械通气治疗。死亡10例,病死率为15%(10/66);治愈、好转56例(85%)。结论鄂西南地区新生儿ARDS以轻/中度为主;围生期窒息和感染可能是该地区新生儿ARDS的主要病因;脑室内出血是最常见的合并症;综合治疗后患儿存活率较高。
