Criteria for evaluating evidence that laboratory abnormalities are associated with the development of venous thromboembolism

The identification of conditions associated with an increased risk of venous thromboembolism may indicate the need for aggressive prophylaxis during periods of high risk, prolonged anticoagulant therapy after an initial venous thromboembolic episode, the investigation of asymptomatic family members and the avoidance of oral contraceptives. Advances in laboratory medicine have led to the identification and assessment of many proteins responsible for normal hemostasis, and associations between abnormalities in a number of these proteins and venous thromboembolism have been reported. Without the ability to appraise this information critically, physicians may be unable to determine whether or how they should modify their clinical practice. Criteria for determining whether specific laboratory abnormalities have a relationship with venous thromboembolism are proposed here, and one example of the application of these guidelines is provided.     

康复新液治疗复发性口腔溃疡的临床疗效观察

目的分析康复新液治疗复发性口腔溃疡的临床疗效。方法136例复发性口腔溃疡患者,按照计算机分组法分为对照组与实验组,各68例。对照组使用生理盐水治疗,实验组使用康复新液治疗。对比两组疗效、治疗后相关指标变化、临床症状评分及链球菌、韦荣菌与奈瑟菌检测结果。结果实验组患者治疗优良率为97.06%,高于对照组的86.76%,差异有统计学意义(P<0.05)。治疗后,实验组CD3^+、CD4^+、CD8^+、肿瘤坏死因子-α(TNF-α)、白细胞介素-2(IL-2)、白细胞介素-10(IL-10)水平均优于对照组,差异有统计学意义(P<0.05)。实验组患者溃疡面积、溃疡个数、渗出、充血、疼痛、烧灼感疼痛评分均低于对照组,差异有统计学意义(P<0.05)。实验组患者链球菌、韦荣菌与奈瑟菌检测结果分别为(8.00±0.30)、(8.10±0.31)、(8.51±0.35)拷贝/ml,均优于对照组的(7.54±0.26)、(7.71±0.28)、(8.98±0.38)拷贝/ml,差异有统计学意义(P<0.05)。结论康复新液治疗复发性口腔溃疡的疗效显著,可快速缓解疾病症状,具有推广价值。

内蒙古药用植物种质资源调查及保护思路探讨

药用植物种质资源保护是蒙中药材持续健康发展的基础。内蒙古自治区蕴藏着丰富的药用植物种质资源,然而,由于野生资源乱采滥挖严重,导致了遗传多样性的损失和生态环境的破坏;另一方面,长期对种质研究的不重视,蒙中药材只种不选,导致药用植物种质资源匮乏并且种质混杂、退化现象严重,进而严重影响内蒙古自治区蒙中药材的质量和产量。本文通过对全区种质资源现状进行分析,指出现存问题和所关注重点,提出相应的建议对策,旨在引起相关行业科研工作者的重视并提供一定的参考。     

Family Consumer Behaviors,Adolescent Prediabetes and Diabetes in the National Health and Nutrition Examination Survey (2007–2010)

Background: Prediabetes or diabetes (characterized by hemoglobin A1c [HbA1c] levels ≥ 5.7 gm%) has been associated with numerous long-term complications. Family consumer behaviors are important risk factors that lead to impaired glucose tolerance or diabetes. However, few studies have studied the association between the family consumer environment and prediabetes and diabetes in adolescents.

Objective: The aim of this study was to examine the association between family consumer behaviors (healthy food availability and supermarket spending) and adolescent prediabetes and diabetes (ClinicalTrials.gov identifier #NCT03136289.)

Methods: Data from a nationwide survey conducted by the Centers for Disease Control and Prevention (National Health and Nutrition Examination Survey [NHANES] 2007–2010 data) were used for these analyses. Adolescents aged 12–19 years were selected for this study. Bivariate analyses and logistic regression models assessed the relationship between family consumer behaviors and the prevalence of adolescent prediabetes and diabetes. Multivariable models adjusted for age, gender, ethnicity, physical activity, education, income, and household size.

Results: A total of 2520 adolescents were eligible for this study. Adolescents with healthier household food availability had negative odds (odds ratio [OR] = 0.74, 95% confidence interval [CI], 0.55–1.00), as did higher log supermarket spending (OR = 0.69; 95% CI, 0.57–0.85). Interaction models demonstrated that adolescent females had more negative odds of prediabetes/diabetes for both healthier food availability (OR = 0.79, 95% CI, 0.39–1.29) and for greater log supermarket spending (OR = 0.69, 95% CI, 0.57–0.85).

Conclusion: This study shows that both healthy food availability and an increase in supermarket spending were associated with a decreased adjusted prevalence of prediabetes and diabetes in adolescents, with a greater effect in females. These results suggest the need for policy and dietary interventions targeting the consumer environment.     

Sentinel lymph node biopsy in head and neck rhabdomyosarcoma

Head and neck rhabdomyosarcoma lymph node staging is challenging due to varied patterns of lymphatic drainage and the suboptimal predictive value of available imaging modalities. Furthermore, regional relapse rates are unacceptably high, and the toxicity of empiric radiation is undesirable in the pediatric and young adult population. In an attempt to improve locoregional control without excess morbidity, we have adopted routine sentinel lymph node biopsy in head and neck rhabdomyosarcoma, which is safe and feasible in pediatric patients. Of six procedures reported here, pathologic findings led to intensification of regional and/or systemic therapy in two patients.
