持续性特发性耳鸣严重程度的相关因素分析

目的 探讨导致持续性特发性耳鸣严重程度的相关因素。 方法 分析870例持续性特发性主观性耳鸣患者的一般资料、病史、听力学结果、耳鸣匹配实验、耳鸣残疾量表、匹兹堡睡眠质量指数量表和焦虑自评量表,应用多因素Logistic回归分析研究与患者耳鸣严重程度相关的因素。 结果 (1)性别(P<0.001)、年龄(P=0.010)、耳鸣主调声频率(P=0.005)、听力损失(P=0.037)、焦虑程度(P<0.001)、睡眠状况(P<0.001)在THI分级上差异有统计学意义(P<0.05);(2)病程(P=0.053)、侧别(P=0.437)、主调声响度(P=0.120)在THI分级上差异均无统计学意义(P>0.05)。 结论 女性患者特发性耳鸣的程度较男性更为严重;低频较高频更扰人;焦虑程度和睡眠状况是影响耳鸣严重程度的因素,而病程、侧别、耳鸣主调声响度不是影响患者特发性耳鸣严重程度的因素。     

Challenges in platelet inventory management at a tertiary care oncology center during the novel coronavirus disease (COVID-19) pandemic lockdown in India

The novel coronavirus disease (COVID-19) has been declared a pandemic by the world health organization and to limit the spread of the disease, many countries in the world, including India, had enforced a lockdown. Despite no restriction over the platelet donation activities, plateletpheresis donors became apprehensive regarding the possible risk of spread of the COVID-19 during the platelet donation and in the hospital premises. Many of them started hesitating for platelet donations. With this, the blood center started having an acute shortage of platelets. Various confidence-building steps were implemented by the blood center to promote voluntary plateletpheresis. The blood center staff and individual donors were educated to prevent the spread of COVID-19. The donor organizations and plateletpheresis donors were informed about the steps to be taken by the blood center during the donation and necessary steps for the prevention of the possible spread of COVID-19. With the help of these measures, the confidence of the individual platelet donors and the donor organizations was restored in the blood center and regular plateletpheresis was continued. These measures may also be useful to other blood centers in the COVID-19 pandemic and this experience may be useful if a similar pandemic lockdown happens in the future.     

大学生心理素质与思想品德发展的关系

研究大学生心理素质与思想品德发展的关系，目的在于分析、发现个体在接受教育过程中的心理运动规律，从而提高思想教育的实效性。本文从马克思主义认识论和实践论的观点出发，依据教育心理学的原理，探讨了心理健康教育与思想品德教育的内在联系和相互作用，提出良好的心理素质是大学生思想品德发展的基础的观点。认为品德的形成与人的心理活动息息相关，个体如果没有良好的品德，将影响其心理素质的完善；同样，没有健全的心理素质，思想品德也不能得到很好的发展。只有思想品德教育与心理健康教育协调发展，共同作用，才能收到良好的教育效果。     

68例社区获得性肺炎病原及临床特征分析

目的　 68例外周血白细胞正常或降低的社区获得性肺炎 (CAP)病原及临床特点分析。方法　检测CAP患者呼吸道及血液标本的常见病原体 ,并分析其临床特点。结果　军团菌属占 2 2 .1 % (1 5/ 68) ,肺炎支原体占 1 1 .8% (8/ 68) ,病毒占 1 6 .2 % (1 1 / 68) ,其中甲型流感病毒 2例、乙型流感病毒 5例 ,副流感病毒 1例 ,腺病毒 1例 ,艾滋病病毒 2例。细菌占 2 .9% (2 / 68) ,有 47.1 % (32 / 68)不能明确病原体 ,混合感染率为 8.8% (6/ 68)。病毒性肺炎、军团菌肺炎及肺炎支原体肺炎的临床症状、体征、外周血白细胞、胸部影像均无特异性 ,其鉴别需靠病原学检查。结论　外周血白细胞正常或降低的CAP病因主要为非典型病原体和病毒 ,对此类CAP的经验治疗应首选大环内酯类抗生素或抗病毒药物。     

伴ADHD的对立违抗性障碍儿童行为特征分析

目的：了解伴注意缺陷／多动障碍(ADHD)的对立违抗性障碍(0DD)患儿的行为特征。方法：以ICD-10作为诊断标准对门诊就诊儿童进行诊断，得到ODD伴ADHD者40例(64.52％)．ODD不伴ADHD者22例(35．48％)。自编家庭情况调查表调查患儿的基本情况。用家长填Achenbach儿章行为量表评定儿童行为。结果：与ODD组相比。合并ADHD组的家长更多对患儿经常打骂和严厉管教：对儿童的不良行为更多地采取打骂的方式。合并组父亲急燥易怒者比ODD组多；合并组起病年龄及就诊年龄比ODD组早：合并组在CBCI。思维、注意问题，违纪、攻击行为，外化性问题，行为总分均高于ODD组。结论：ODD合并ADHD的患儿在思维、注意问题，违纪、攻击行为，外化性问题方面表现更突出，家长对儿童管教方式及不良行为处理方式影响ODD的发生。提示要注重ODD、ADHD的早期干预。     

Validation of silver-stained nucleolar organizer regions for evaluation of invasive character of urinary bladder carcinoma in rats and mice

A series of 8 rat and 16 mouse invasive bladder carcinomas were investigated for the presence of silverstained nucleolar organizer regions (AgNORs) to clarify whether this parameter is applicable to the estimation of their invasive character. With regard to number of AgNORs per cell, neither rat nor mouse carcinomas showed any difference between invasive and noninvasive sites within the same tumor. However, the frequency of cancer cells bearing bizarre dots, irregular in size and shape, was significantly higher at sites of actual invasion. Quantitative data generated using an image analyzer revealed significantly lower values for NOR roundness and significantly larger NOR size in invasive sites than in noninvasive sites in all groups. Double staining for the proliferation marker proliferating cell nuclear antigen (PCNA) and AgNORs was performed on eight rat carcinomas and a close correlation between the two was confirmed. Thus the number of AgNORs in PCNA-positive cells was significantly greater than in PCNA-negative cells. Furthermore, a particularly strong correlation was observed for incidences of PCNA-positive cells and bizarre dots (P<0.01). The quantitative data also demonstrated significant differences in size and shape of dots. It is concluded that AgNORs have diagnostic value for the invasive character of bladder carcinomas.     

中国军人个性特征的调查分析

为了解我军不同人员的个性特征，建立军人的艾森克个性问卷（ＥＰＱ）常模，为我国军事心理学研究提供依据，采用修订的ＥＰＱ（成年）对全军１９６２２人的个性特征进行了调查，其中陆军１３２４５人，海军１２８４人，空军１５８３人，学员３５１０人。结果：军人精神病质和神经质量表分均显著低于全国常模，内外向量表分高于全国常模，效度量表分则与全国常模近似。军人个性的内外向以中间居多（５２．５％）、其余依次为外向（１９．７％）、倾向外向（１８．２％）、倾向内向（５．９％）和内向（３．７％）；情绪稳定度呈中间、稳定、倾向稳定、倾向不稳、不稳者分别占４３．９％、１９．８％、１４．９％、１１．５％和９．９％。提示军人个性有其特征，本研究结果可作为我国军人的ＥＰＱ常模。     

抑郁障碍患者人格特征与发病关系的研究

目的探讨抑郁障碍患者的人格特征与其疾病发病间的关系。方法采用自评抑郁量表(SDS)、艾森克人格问卷 (EPQ)、应对方式评定量表 (WCRS)和归因方式问卷 (ASQ)对 76名抑郁障碍患者进行测试 ,同时选取 84名健康被试进行对照研究。结果①抑郁组患者在EPQ中神经质 (N)与精神质 (P)的得分显著高于健康组。②WCRS的结果显示在“宣泄接纳”、“退避调节”两个因子上 ,抑郁组的平均得分低于健康组。③在ASQ的得分中 ,抑郁组在负性事件归因的自身性、持久性和整体性均显著高于健康组。④抑郁障碍患者的“神经质”人格特质与应对方式的“宣泄接纳”和“退避调节”因子呈负相关 (r = 0 .474)。结论抑郁障碍患者的人格特征可表现为较强的神经质及孤僻、交往障碍 ,他们这种人格特征及应对和归因方式在其发病过程中起着重要作用。
