Restudy on morphology of Oryctocephalus indicus (Reed, 1910), based on specimens from Guizhou, China and Nevada USA, suggests that the subspecies regarded previously as Oryctocephalus indicus indicus (Reed, 1910), O. indicus latus Zhao et Yuan 2002, and O. indicus kobayashi Saito, 1934, are synonymous, and Oryctocephalus americanus Sundberg et McCollum, 2003 is a similar form of O. indicus. Oryctocephalus indicus is rediagnosed as having a glabella that is subconical in outline and tapering forward slightly; a thorax that comprises 12 segments, and a small pygidium that bears 2—3 axial rings with a terminal piece and a postaxial ridge. Oryctocephalus indicus is widely distributed in eastern Guizhou and ranges through a great interval of Kaili Formation. Its first appearance is almost identical with these events of trilobite extinction-recovery occurring at the end of the Early Cambrian, the alternation of acritach assemblages, the change of trace elements (REE) and stable isotopes (carbon) at the Wuliu-Zengjiaya section. As one of the key forms for defining the traditional Lower-Middle Cambrian boundary (the base of Cambrian Series 3 and Stage 5 in the new Cambrian chronstratigraphic standard), O. indicus has received detailed study and has more advantages than other species such as Ovatoryctocara granulata Tchernysheva, 1962 or Arthricocephalus chauveaui Bergeron, 1899.

目的:探讨急性重症胰腺炎(SAP)患者发生肠内营养不耐受的相关影响因素及其干预措施。方法:回顾性分析2019年2月-2020年12月赣州市人民医院收治的115例SAP患者的临床资料,分析SAP患者发生肠内营养不耐受的相关影响因素。结果:115例SAP患者,出现肠内营养不耐受62例(53.91%),肠内营养耐受53例(46.09%)。单因素分析显示:APACHEⅡ评分、血糖、添加膳食纤维、腹内、血清白蛋白水平与SAP患者发生肠内营养不耐受均有关,差异均有统计学意义(P0.05)。多因素分析显示:APACHEⅡ评分≥20分、血糖≥11.1 mmol/L、腹内压>15 mmHg、血清白蛋白水平<25 g/L均是SAP患者发生肠内营养不耐受的高危因素(P<0.05),添加膳食纤维是SAP患者发生肠内营养不耐受的保护因素(P<0.05)。结论:SAP患者发生肠内营养不耐受与APACHEⅡ评分、血糖、腹内压、血清白蛋白水平均密切相关,添加膳食纤维是SAP患者发生肠内营养不耐受的保护因素,临床可针对各危险因素加强护理措施干预。

目的探讨在患有脑后部可逆性脑病综合征患者的临床诊断方式选择当中,CT与MRI的不同应用效果。方法选择本院2018年1月~2019年10月收治的25例脑后部可逆性脑病综合征患者作为主要研究对象,让其入院后分别接受CT扫描与MRI扫描诊断,对两组患者的具体检查情况、确诊情况进行分析。结果所有患者接受MRI扫描检查的确诊情况多于CT检查,MRI确诊例数25例,CT确诊例数23例,但是两种检查方式的相关数据对比后无差异(P>0.05),在所有患者当中,21例患者治疗8~20 d后症状基本消失,患者接受CT检查显示病灶多为低密度病灶,MRI检查则出现高信号表现。结论对于患有脑后部可逆性脑病综合征患者的诊断,让其接受MRI的诊断效果要稍好于CT扫描诊断,可作为这类患者的首选诊断方式进行应用。

[Objective] This study aimed to investigation the effects of straw covering and different types of potassium fertilizer on salinity accumulation in surface layer of tobacco-planted paddy soil in southern China. [Method] Tobacco variety ‘Yunyan87’ was used as the experimental material to investigate the effects of salinity accumulation in surface layer of tobacco-planted paddy soil on the growth and development of flue-cured tobacco using different types of potassium fertilizer and mulching cultivation methods. [Result] The results showed that K＋ , Ca2＋ , SO42and NO3-were the major salt ions in topsoil at different growth stages of flue-cured tobacco, Na ＋ and Mg2＋ contents were also relatively high at vigorous growth stage, indicating that these salt ions were easily accumulated in surface layer of soil; to be specific, the absolute increase of salt ion concentration showed a decreasing order of K＋ SO42- NO3-Ca2＋ Mg2＋ Na＋ Cl-, while the relative increase of salt ion concentration showed a decreasing order of Ca2＋ K＋ Na＋ NO3-SO42-Mg2＋ Cl-. At 60 d posttransplanting, total salt content in topsoil reached the minimum of 359.1 mg/kg in Treatment 2, total salt content in topsoil reached the maximum of 536.1 mg/kg in Treatment 5 （CK）, which was significantly higher than that in other treatments. At 90 d post-transplanting, no significant difference was observed in total salt content among various treatments. At harvesting period, total salt content in topsoil reached the maximum of 3 278.4 mg/kg in Treatment 1, which was significantly higher than that in other treatments. Topsoil pH showed no significant differences among various treatments at three different periods, ranging from 5.39 to 5.59. Straw covering could effectively reduce salt content in topsoil, accelerate vigorous growth of tobacco, shorten vigorous growth period and increase plant height, leaf number and lead area; at vigorous growth stage, root vitality and root volume of tobacco were improved, but the yie
