抑郁症患者与非抑郁症人群中儿童期虐待与社会支持的关系

目的 研究抑郁症患者与非抑郁症人群中儿童期虐待与社会支持的关系。方法 本研究 采用非匹配的病例对照研究，对2014 年1 月至2017 年12 月北京安定医院符合入排标准的研究对象进行 研究，共连续纳入224 例抑郁症患者及214 例非抑郁症人群。采用调查问卷（自编）收集研究对象的基本 信息（年龄、性别、婚姻状态、教育水平、工作状态、吸烟史及体质量指数）、疾病史、精神疾病家族史；采 用儿童期虐待问卷中文版（CTQ-SF）评估研究对象16 岁前的经历；采用社会支持评定量表（SSRS）评估 研究对象在过去生活状态中获得的社会支持情况，包含客观支持、主观支持和支持利用3 个维度。采 用单因素分析对抑郁症患者与非抑郁症人群进行基本资料、CTQ-SF及SSRS 评分的比较，采用多因素 Logistic 回归分析影响成年期患者抑郁发生的因素。结果 抑郁症患者中有儿童期虐待经历者（93 例， 41.52%）多于非抑郁症人群（51 例，23.8%），差异有统计学意义（χ2=15.51，P ＜ 0.01）。多因素Logistic 回 归分析显示，儿童期虐待是成年期抑郁的重要危险因素（OR=2.030，95%CI：1.302～3.164）。抑郁症患者 社会支持总分［（32.33±7.45）分］、主观支持［8（6，10）分］、客观支持［17（14，21）分］及支持利用度得分 ［6（5，8）分］均低于非抑郁症人群［分别为（36.79±6.24）、9（7， 11）、20（17， 23）、8（6， 9）分］，差异均有统 计学意义（均P＜0.01）。抑郁症患者中，有儿童期虐待者社会支持得分［（30.41±7.99）分］、主观支持得分 ［7（5，9）分］、客观支持得分［（16.57±4.78）分］均低于无儿童期虐待经历者［分别为（33.70±6.76）、9（7，10）、 （18.53±4.35）］，差异均有统计学意义（均P ＜ 0.01）；非抑郁症人群中，有儿童期虐待者主观支持得分 ［8（6，10）分］低于无儿童期虐待经历者［9（7，11）分］，差异有统计学意义（P ＜ 0.01）。结论 儿童期虐 待是成年期抑郁症及获得社会支持的重要影响因素。     

25例新型冠状病毒肺炎患者的病情观察及护理体会

目的观察25例新型冠状病毒肺炎患者的病情变化,并总结护理体会。方法选取2020年1月22日—2月20日确诊为新型冠状病毒肺炎后由120急救车转入内科继续治疗的25例患者。对25例集中收治的新型冠状病毒肺炎的患者进行观察,给予规范治疗,实施针对性的护理干预,包括消毒隔离与防护、一般护理、加强监测、药物的治疗与护理、中医护理及心理护理。结果25例患者中发热21例,咳嗽、咳痰13例,乏力、肌肉酸痛7例,胃纳差12例,腹泻5例,胸闷12例,头痛5例。23例胸部CT示两肺单发或散在多发的多叶段的高密度斑片状磨玻璃影,2例出现了实变影和支气管充气征等。25例患者经过治疗与护理后,患者均达治愈标准并予以出院,1个月后随访未出现复发。结论新型冠状病毒肺炎患者初期临床主要表现为乏力、发热、咳嗽、胃纳差、恶心、腹泻,部分患者伴有胸闷,呼吸困难等。护理人员在做好自身防护的同时,密切监测患者病情变化,并实施中西医结合的护理方法,不仅避免了自身感染风险,而且保障了患者的生命安全。     

Knockdown of Nestin inhibits proliferation and migration of colorectal cancer cells

Nestin, a member of type VI intermediate filament protein family, is widely expressed in mammalian nervous tissue and stem/precursor cells of non-neuronal normal tissues. Nestin has also been investigated to determine possible tumor-promoting functions. However, whether Nestin is involved in colorectal cancer (CRC) cells remains unclear. In this report, Nestin expression was upregulated in stromal cells of human CRC tissues. Endogenous Nestin expression in CRC cell lines SW480 and HCT116 was knocked down by a lentivirus. MTT and colony formation assays revealed that Nestin deletion significantly inhibits the proliferation of CRC cell lines; flow cytometer analysis showed that Nestin deletion causes cell cycle arrest at S phase. Transwell chamber and wound healing scratch assays also revealed that Nestin deletion suppresses cell migration. Our findings indicated that Nestin plays an essential role in CRC progression; thus, Nestin can be applied as a therapeutic target of CRC.     

Prevalence of heterophoria in a population of school children in central China:the Anyang Childhood Eye Study

AIM:To investigate the prevalence of heterophoria and the relationship between heterophoria and refractive error in a school-based study conducted in central China.METHODS:A total of 23637 th-grade children were recruited into the cross-sectional school-based Anyang Childhood Eye Study(ACES)by cluster sampling method.Heterophoria was examined using alternate cover and cover-uncover testing.The Maddox rod and prism test were conducted at 33 cm and 6 m distance fixation.Uncorrected viual acuity(UCVA)and best-corrected viual acuity(BCVA)were recorded as logarithm of the minimum angle of resolution(logM AR)with cycloplegic autorefraction by administrating of Mydrin-P and 1.0%cyclopentolate.Hyperopia was defined as the spherical equivalent(SE)refraction of+0.50 D or greater,and higher hyperopia was defined as+2.00 D or greater.Emmetropia was defined as the SE refraction in the range of-0.49 to+0.49 D,and myopia was in the SE refraction range from-0.50 D to less.RESULTS:Totally 2260 students in grade 7 were examined.Response rate among eligible children was 95.64%.Totally 486 children,22.66%of the population,were diagnosed with heterophoria in which 479 were diagnosed with exophoria at near distance,and 6 with esophoria.Totally 89(4.15%)children were diagnosed with heterophoria in which 82 had exophoria,and 7 had esophoria at far distance.Exophoria was common at near fixation(22.33%).Myopia was examined to be related to exophoria at near distance(OR 3.03,95%CI 2.33-3.95)and far distance fixation(OR 1.90,95%CI 1.09-3.32).CONCLUSION:Exophoria is a predominant heterophoria for 7 th-grade junior school in central China.Significant associations are discovered between heterophoria and refractive error.Hyperopia is associated with esophoria,and myopia is associated with exophoria.     

短暂性全面遗忘相关危险因素的临床研究

目的探讨短暂性全面遗忘(transient global amnesia,TGA)患者脑血管危险因素、临床特点、影像学特征、预后及与短暂性脑缺血发作(TIA)的相关性。方法回顾性分析大连医科大学附属第一医院神经内科收治的TGA患者61例为TGA组和TIA患者61例为TIA组,对比2组脑血管危险因素、临床特点及影像学特征,TGA组随访6个月。结果与TIA组比较,TGA组高血压、糖尿病、冠心病、吸烟、血脂异常、高同型半胱氨酸血症及TG水平明显降低(P<0.05,P<0.01),症状持续时间明显延长[300.0(150.0,480.0)min vs 20.0(5.0,60.0)min,P=0.000]。TGA组6个月内无缺血性脑卒中发生,TGA组复发患者9例(14.75%),复发患者与未复发患者年龄、性别、高血压、糖尿病、冠心病、血脂异常、高同型半胱氨酸血症及同型半胱氨酸水平等脑血管危险因素比较,无统计学差异(P>0.05)。TGA组发作前有潜在诱发因素或事件15例(24.59%)。TGA组颈动脉、颅内动脉粥样硬化发生率明显低于TIA组(9.84%vs 80.33%,P<0.01;32.79%vs 59.02%,P<0.05)。结论 TGA与脑血管危险因素不相关,其发病与病前应激因素及潜在诱发因素或事件相关。TGA是一个良性病程,预后较好,可能不是TIA的一种特殊亚型。
