目的系统评价多烯磷脂酰胆碱注射液治疗酒精性肝病(ALD)的有效性和安全性。方法计算机检索PubMed、Embase、the Cochrane Library、***、中国知网、SinoMed、维普和万方数据库,搜集有关多烯磷脂酰胆碱注射液治疗ALD的随机对照临床试验(RCT),检索时限均为建库至2022年12月31日。由2名研究者独立筛选文献、提取资料并评价纳入研究的偏倚风险后,使用Stata 17.0软件进行随机效应模型的Meta分析。结果最终纳入10个RCT,包含809例患者。Meta分析结果显示,多烯磷脂酰胆碱注射液组的有效率高于对照组[RR=1.12,95%CI(1.04,1.20),P=0.0038];与对照组相比,多烯磷脂酰胆碱注射液可以降低丙氨酸氨基转移酶(ALT)水平[MD=-18.92 U/L,95%CI(-27.75,-10.09),P<0.001]、天门冬氨酸氨基转移酶(AST)水平[MD=-31.19 U/L,95%CI(-46.27,-16.11),P=0.0001]、总胆红素(TBiL)水平[MD=-7.31μmol/L,95%CI(-10.75,-3.88),P<0.001]和γ-谷氨酰转肽酶(GGT)水平[MD=-48.93 U/L,95%CI(-54.64,-43.21),P<0.001]。仅1项研究报告了轻度的不良反应,6项研究均报告患者未出现明显不良反应。结论当前证据显示,多烯磷脂酰胆碱注射液治疗ALD可以提高有效率,改善肝功能指标(ALT、AST、TBiL、GGT)的水平,不良反应较少。受纳入研究数量和质量的限制,上述结论尚需开展更多高质量研究予以验证。

The growth of tobacco is sensitive to environment conditions. The tobacco production is strictly restricted by regional cultivated land. Based on the principal of hiberarchy analysis and fuzzy mathematics and the technique of geographic information system （GIS）, the comprehensive evaluation of tobacco ecology suitability were studied according to the actual circumstances of the whole Henan tobacco planting regions, China. The evaluation index system of tobacco ecology suitability of Henan tobacco planting regions was established by choosing 17 evaluation indexes from 3 respects of climate, soil and landform with Delphi method. Furthermore, the membership function was set up according to the effects of each ecology factors on the growth and quality of tobacco suitability. And the analytical hierarchy process （AHP） was used to determine the weight of indexes by using quantitative analysis. Then the tobacco ecology suitability map of Henan tobacco plantation was drawn with GIS software mapGIS. It is found that the most areas of the western and southern parts of Henan Province, China, are the highly suitable regions, accounting for 22.52% of Henan tobacco planting areas. It is because that there are medium air temperature, sunshine and rainfall, medium soil pH value, and high contents of soil organic matter in the regions. Moreover, the topography is hill and massif, and the height above sea level is between 150-800 m there. Some areas of the southern and middle parts of Henan Province are the suitable ones, accounting for 34.99% of Henan tobacco planting areas. It is because that there are enough rainfall, medium air temperature, high contents of available N and available K in the soil in these regions. There are less suitable regions in the northern and eastern parts of the investigated regions because of drought, too high pH value and CI in the soil and irrigation water, accounting for 35.54% of the whole areas. It can be conducted rapidly and correctly by combining

幼胚是目前广泛用于玉米组培再生和遗传转化的主要外植体材料,但获取幼胚的数量和质量会受到季节和气候条件的严重影响。通过将玉米子粒在4℃条件下浸泡3 d获得萌动胚,进而以其为外植体,建立玉米组培再生体系。通过调整培养基组成和激素配比,萌动胚在2,4-D浓度为8 mg/L的诱导培养基上,初代愈伤组织发生率可达到54.17%,经继代培养胚性愈伤诱导率可达42.13%。胚性愈伤组织在激素组合为1.5 mg/L 6-BA+0.1 mg/L NAA的分化培养基上分化率超过40%,经生根培养后可100%生根。基因表达分析同时发现,与体细胞发生相关的7个基因在不同培养阶段的表达变化与胚性愈伤组织的形成密切相关。结果表明,玉米萌动胚可替代幼胚或作为其补充用于玉米组培再生和遗传转化相关工作。

The acidic, corrosive effect of sodium polystyrene sulfonate(PSS) in poly 3,4-ethylenedioxythiophene:sodium polystyrene sulfonate(PEDOT:PSS) limits the stability of inverted perovskite solar cells(PSCs) based on the ITO/PEDOT:PSS/perovskite/PCBM/BCP/Ag structure. In this work, a poly 3,4-ethylenedioxythiophene(PEDOT) hole transport layer(HTL) with high hole mobility and good catalytic performance was prepared by electrochemical cyclic voltammetry(CV) method for inverted PSCs. By controlling the CV cycles(from 1 to 5 cycles) and EDOT monomer solution concentration(from0.5 to 2.0 mmol·L^(-1)) of electrochemical deposition, the thickness, morphology, optical and electrochemical properties of PEDOT could be accurately adjusted. The optimal photovoltaic performance with current density(J_(sc)) of 22.19 mA·cm^(-2), open circuit voltage(V_(oc)) of 0.94 V, fill factor(FF) of 0.65 and photoelectric conversion efficiency of 13.56% was obtained when deposition of PEDOT with 1 CV cycle and EDOT concentration of 0.5 mmol·L^(-1). At this point, the perovskite showed good crystallization,optimal optical, charge transport and recombination performance, resulting in better V_(oc)and photoelectric conversion efficiency(PCE) compared to the devices with higher CV cycle numbers and 3,4-ethylenedioxythiophene(EDOT) concentration. For comparison with spin-coated PEDOT:PSS, the device with electrodeposited PEDOT showed improved J_(sc)and comparable V_(oc), which may result from its better charge transport and catalytic *** device with spin-coated PEDOT:PSS showed photoelectric conversion efficiency of 12.25%, which was lower than that based on electrodeposited PEDOT(13.56%) with1 CV cycles and 0.5 mmol·L^(-1) EDOT concentration. And the device with electrodeposited PEDOT as HTLs showed more excellent air stability. In ambient air((32 ± 5) ℃ and RH: 70% ± 20%), it still maintained more than 80%of the initial photoelectric conversion efficiency after1000 h. In comparison, the photoe
