社交焦虑障碍患者父母的人格特征和心理健康状况调查

目的探索社交焦虑障碍(SAD)患者父母的人格特征和心理健康状况。方法设研究组(SAD患者的父母)和对照组。入组时按要求进行艾森克人格问卷(EPQ)和症状自评量表(SCL-90)评定。结果SAD患者的父母在EPQ量表测验中的内外向因子标准分低于对照组;SAD患者的父母SCL-90各项因子除强迫和敌对因子,标准分低于对照组。结论SAD患者的父母的人格特征倾向内向,易安静、内省、离群、不喜欢接触人;SAD患者的父母更容易表现出躯体化症状、人际交往的困惑、抑郁、焦虑、恐怖和偏执。     

2001年广西疟疾防治效果及流行特征分析

目的：分析2001年全区疟疾防治效果、流行趋势、流行特征，为疟疾防治与监测提供依据。方法：对全区2001年疟疾监测结果和调查结果资料进行分析研究。结果：2001年全区疟疾发病率、居民原虫阳性率分别比上年降低21．74％及16．67％，91．49％的当地感染的病人分布在山区县，86．02％的病灶村为1例病人。流动人口检出疟疾病例数占各类人群血检检出疟疾病例总数的87．89％，外出回归人员检出病例中84．79％的病人从事与野外作业相关的工种。结论：全区大部分地区为低疟区，局部地区疟疾传播仍未阻断。流动人口和山区复媒地区是当前疟疾监测的重点。     

神经梅毒的临床特征与诊断分析

目的：分析神经梅毒的分型和临床特征及提供早期诊断依据。方法：回顾性分析经临床和实验室检查确诊的18例神经梅毒病人的有关临床资料。结果：神经梅毒的临床特征包括：(1)急性、亚急性起病为主；(2)临床以间质型，尤其是以脑卒中起病常见，症状元特异性；(3)血清学检查以梅毒螺旋体血凝试验(TPHA)及快速血浆反应素试验(RPR)特异性较高；(4)脑脊液检查表现为压力增高(42．9％)、蛋白增高(81．2％)及细胞数增高(56．3％)；(5)头颅CT、MRI表现与高血压、动脉硬化所致脑梗死不同，为多发、散在病灶。结论：神经梅毒早期误诊率高，临床表现与分型密切相关，实验室及影像学检查是诊断的重要依据。     

Methods of Measuring Community Characteristics

There is increasing interest in the influence of community characteristics on child development and family functioning. In order to address questions on community influence, it is important to be aware of the measures available and their strengths and limitations. Useful strategies have been developed within a number of disciplines, including sociology, social and community psychology, and criminology. Methods include summarising information from existing administrative databases and census data, conducting observations, and using survey instruments with residents. The most commonly used methods are reviewed and their psychometric properties described .     

Mental retardation,structural anomalies of the central nervous system,anophthalmia and abnormal nares: A new MCA/MR syndrome of unknown cause

We report on 2 unrelated Brazilian girls, born to nonconsanguineous parents, and presenting structural central nervous system defects, hydrocephaly, macrocephaly, craniosynostosis, prominent forehead, anophthalmia, and abnormal nares. These patients may have a previously undescribed recurrent-pattern cerebro-oculo-nasal syndrome. © 1993 Wiley-Liss, Inc.     

四川省绵阳市2019—2021年流行性感冒流行病学特征分析

目的 了解绵阳市2019—2021年流行性感冒流行病学特征,为绵阳市流感防控工作提供重要依据。方法 收集绵阳市2019—2021年流感监测相关数据,采用描述性流行病学方法进行统计学分析。结果 绵阳市2019—2021年流感共报告发病55 970例,年均报告发病率388.08/10万。报告流感样病例（influenza-like illness cases, ILI） 103 723例,年平均ILI%为3.58%。2019年流感报告发病率、ILI%、阳性检出率均远超过历年同期水平。人群分类构成以15岁以下学生为主。报告发病数居前三位的地区分别为涪城区20 118例（占35.94%）、游仙区6 394例（占11.42%）、江油市5 800例（占10.36%）。2019—2021年共收到并检测ILI标本10 126份,阳性率19.53%;标本阳性检出率以15岁以下学生为主。历年流感病毒优势毒株呈现出交替流行的趋势,2019年以A（H3）型为主,2020年受新冠疫情影响,全年阳性检出率均较低,2021年除检出2份A（H9）型外,其余均为BV型。2019—2021年共报告ILI暴发疫情43起,发生时间主要集中在冬季,场所以小学居多。结论 2019—2021年绵阳市流感病例、ILI、病原学监测、暴发疫情的特征基本一致,15岁以下的学生及学校仍为重点关注人群及场所。而新型冠状病毒肺炎疫情大流行下,流感的低发水平进一步印证非药物干预措施对流感防控工作的重要性。     

A psychosocial study of male prostitution

A semistructured questionnaire was administered to 50 male prostitutes and 50 nonprostitutes matched on age, sex, and socioeconomic status. The questionnaire focused on areas pertaining to family, sexual and criminal history, current life situation, sexual practices with clients, substance abuse, etc. In addition, the Beck Depression Inventory and the Tennessee Self-Concept Scale were administered to 35 subjects from each group. Results indicated that there were differences between the groups but that these differences did not entirely support the demographic profile offered by previous researchers. Specifically, our findings suggest that factors related to family background may be less important as potential determinants for entry into prostitution than influences related to financial gain, sexual orientation (homosexuality), and early sexual experiences.This research was supported by a grant from the Donation Richelieu.     

Impedance of goat eye lens at different DC voltages

A computer assisted AC impedance system is used to measure the DC voltage—current (V-I) characteristics and AC impedance of a goat eye lens using a two-probe Ag−AgCl electrode system. The measurement of the V-I characteristics shows that when a DC voltage from 0mV to 30mV is applied, the resultant current decreases from an initial value of 0.58μA to 0.006μA. However, when the voltage is increases beyond 30mV, the current increases and reaches a value of 0.9μA at 100mV. The data on the frequency response (0.01–10 Hz) of the impedance of lens tissue show an inverse relationship with frequency. The effect of various DC voltages, namely 0, 30, 50, 100 and 200 mV, on the impedance of the eye lens is also investigated over a frequency range of 0.01–10 Hz. The measurement results for both V-I characteristics and AC impedance further suggest the presence of a 30 mV voltage compartment in the goat eye lens.
