一种新的正交参数选优法及其在非线性回归分析中的应用

非线性回归分析是工程中经常采用的一种用来估计数学模型参数的方法，该方法能否顺利运用与参数初始值的选择有极大关系。本研究提出一种新的正交参数选优法——阻尼正交表法，它不仅可以保证非线性回归分析算法的顺利收敛，而且能够显著提高后者的收敛速度，进而极大改善非线性回归分析算法的应用性能。本研究的数值试验及心肌造影超声心动图定量分析应用实例表明，作为对传统正交参数选优法的一种改进，阻尼正交表法在科学与工程计算或信号与信息处理领域有着很好的应用前景。

Human parotid proline-rich proteins: correlation of genetic polymorphisms to dental caries

Parotid saliva contains a variety of proline-rich proteins. This study found that, among 306 children between the ages of 5 to 15 years, there is a significant increase in the decayed-missing-filled tooth surface (DMFS) score of the permanent teeth with age in children with the specific proline-rich protein phenotypes Pa and Pr. However, the increase in DMFS score of the permanent teeth of children was significantly greater in children with Pa+ and Pr22 than in those with the other phenotypes (Pa- or Pr11 and Pr12). The previously established close correlation between the Pa and Pr phenotypes and the genetic variants of salivary peroxidase (a powerful antibacterial system in the oral cavity) may provide an explanation for the relationship of certain proline-rich protein phenotypes to dental caries.     

The impact of surgical treatment on the mental health of women with obstetric fistula

Obstetric fistula is estimated to affect 2 million women worldwide and has considerable social and psychological effects on affected individuals. In this prospective study, 51 consecutive women with obstetric fistula admitted to the Barhirdar Hamlin Fistula Centre in the north of Ethiopia were screened using the General Health Questionnaire (GHQ-28) for potential mental health disorder before and 2 weeks after fistula surgery. Prior to surgery, all women screened positive. By 2 weeks after, this had dropped to 36% ( P = 0.005). 27% of the 45 women who were cured of their incontinence screened positive, while all 6 of those with severe residual incontinence continued to screen positive. We conclude that surgical treatment of obstetric fistula results in marked improvements in mental heath.     

Outcomes of planned home birth: an integrative review

Current evidence indicates the critical importance of several factors that contribute to improved perinatal outcomes: a facilitating environment at the place of birth, skilled birth attendance, and the continuum of perinatal care for women and newborns. This level of care is often referred to as "first-level" care, and is most readily provided in birthing centers and primary level health facilities. However, there is a body of evidence that has been compiled over the past several decades that addresses the safety of planned home birth, under circumstances that emulate these elements of "first-level" care. These studies demonstrate a remarkable consistency in the generally favorable results of maternal and neonatal outcomes, both over time and among diverse population groups. These outcomes are also favorable when viewed in comparison to various reference groups (birth center births, planned hospital births, and vital statistics). These data should influence policy in support of planned home birth, including policy that endorses building or sustaining a home birth infrastructure in parallel to the efforts to build capacity for facility-based birth. Such public policy would also be in keeping with the fundamental right of women to have choice in childbirth, particularly when options are equally good.     

蚌埠市某高中学生亚健康状况及其影响因素分析

目的了解蚌埠市高中学生的亚健康状况,探讨其影响因素,为开展相关健康教育工作提供参考依据。方法整群选取蚌埠市某高中在校学生1409名,采用自编问卷进行调查,所得数据采用SPSS10.0进行统计分析。结果亚健康状况检出率为58.34%,不同性别学生亚健康状况检出率差异无统计学意义,不同年级学生亚健康状况检出率差异有统计学意义（P〈0.01）。亚健康的主要危险因素为经常熬夜、正在减肥、缺乏体育锻炼、学习压力大、学习成绩不理想、睡眠不足等12项。结论蚌埠市高中学生亚健康问题较为突出。应积极采取有效措施,提高学生的健康水平。     

Community-based situation analysis of maternal and neonatal care in South Africa to explore factors that impact utilization of maternal health services

This community situational analysis determined factors impacting the utilization of maternal health services in South Africa. Quantitative and qualitative research methods were used, including semistructured household interviews, case studies of women with no antenatal care and/or home birth, and verbal/social autopsies of maternal and infant deaths, conducted in three diverse sites across the country. Data analysis used quantitative statistics for the semistructured interviews and a qualitative thematic content approach for the case studies and verbal/social autopsies. Each component was analyzed separately and then triangulated. The following themes emerged: 1) transport and distance to care were the biggest problems, particularly in rural areas; 2) providers' communication with families was very poor; 3) health-seeking behavior was better than anticipated; 4) treatment by health providers and quality of care showed mixed results; 5) HIV/AIDS is a major issue; however, basic maternity and neonatal service quality cannot be overlooked; and 6) families and communities are an untapped resource for improving maternal and neonatal health. Implications for maternal and infant health care in developing countries are discussed, with a particular focus on barriers to utilization and involvement of communities and families in maternity care.     

人血浆高敏感性C反应蛋白与代谢综合征相关性分析

目的:了解我国人群血浆高敏感性C反应蛋白(hs-CRP)水平与代谢综合征(MS)关系及其它影响hs-CRP水平的相关因素。方法:1198例血浆标本来自2006年3月~2006年11月在浙江省桐乡市第三人民医院体检人群。采用Beckm an LX20血生化全自动生化仪及其配套试剂,测定上述空腹血浆标本中血糖(FPG)、甘油三脂(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-c)、低密度脂蛋白胆固醇(LDL-c)和hs-CRP水平。MS诊断标准参照中华医学会推荐标准。采用SPSS13.0统计学软件,分析hs-CRP水平与MS关系及其它影响hs-CRP水平的相关因素。结果:男性hs-CRP水平(x±s=1.55±0.53)高于女性(x±s=1.32±0.56)(P<0.001)。15.3%被检者(183/1198)患有MS,其hs-CRP水平明显高于非MS者(P<0.001)。各MS判断指标中,分别有肥胖、高血压病、糖尿病、高TG、低HDL-c时,其hs-CRP水平也明显升高(P<0.001)。排除年龄、性别影响后,hs-CRP水平与MS显著相关(OR值2.18,P<0.001)。结论:hs-CRP水平与MS密切相关,hs-CRP水平增高可作为独立反映MS发生的标志性检测指标。
