深圳市宫颈门诊就诊者高危型人乳头瘤病毒和生殖道沙眼衣原体感染情况

目的 分析深圳地区宫颈门诊就诊者高危型人乳头瘤病毒（high-risk human papillomavirus, HR-HPV）和生殖道沙眼衣原体（genital chlamydia trachomatis, GCT）感染情况及其与子宫颈癌/癌前病变的关联。方法 回顾性地收集2018年1—12月深圳市妇幼保健院妇科宫颈门诊就诊者病历资料,采用非条件Logistic回归分析高危型HPV和GCT与子宫颈病变的关联,计算比值比（odds ratio, OR）和95%置信区间（confidence interval, CI）。结果 本研究纳入深圳市宫颈门诊就诊者881例,平均年龄（36.86±9.46）岁。高危型HPV阳性率为71.7%,GCT的阳性率为7.4%,高危型HPV合并GCT的感染率为5.6%。高危型HPV阳性率随年龄递增（P_趋势=0.001）,而GCT阳性率和高危型HPV合并GCT感染率呈现随年龄逐渐下降的趋势（趋势性P=0.002和0.014）。多因素Logistic回归分析显示,高危型HPV感染与细胞学ASCUS+及病理学CIN1+存在显著关联,OR值及95%CI分别为3.72 （2.35, 5.90）和6.90 （3.79, 12.57）;未发现GCT感染或高危型HPV合并GCT感染与细胞学ASCUS+及病理学CIN1+存在关联。结论 宫颈门诊就诊者是深圳市高危型HPV和GCT感染的重点人群,需有针对性地做好健康教育、安全套促进和常规筛查工作。     

Areca catechu—From farm to food and biomedical applications

The family Arecaceae includes 181 genera and 2,600 species with a high diversity in physical characteristics. Areca plants, commonly palms, which are able to grow in nearly every type of habitat, prefer tropical and subtropical climates. The most studied species Areca catechu L. contains phytochemicals as phenolics and alkaloids with biological properties. The phenolics are mainly distributed in roots followed by fresh unripe fruits, leaves, spikes, and veins, while the contents of alkaloids are in the order of roots, fresh unripe fruits, spikes, leaves, and veins. This species has been reputed to provide health effects on the cardiovascular, respiratory, nervous, metabolic, gastrointestinal, and reproductive systems. However, in many developing countries, quid from this species has been associated with side effects, which include the destruction of the teeth, impairment of oral hygiene, bronchial asthma, or oral cancer. Despite these side effects, which are also mentioned in this work, the present review collects the main results of biological properties of the phytochemicals in A. catechu. This study emphasizes the in vitro and in vivo antioxidant, antimicrobial, anticancer, and clinical effectiveness in humans. In this sense, A. catechu have demonstrated effectiveness in several reports through in vitro and in vivo experiments on disorders such as antimicrobial, antioxidant, or anticancer. Moreover, our findings demonstrate that this species presents clinical effectiveness on neurological disorders. Hence, A. catechu extracts could be used as a bioactive ingredient for functional food, nutraceuticals, or cosmeceuticals. However, further studies, especially extensive and comprehensive clinical trials, are recommended for the use of Areca in the treatment of diseases.     

高效液相色谱法测定人血浆中伏立康唑浓度

目的：建立一种简单高效的高效液相色谱（HPLC）法用来检测人体中伏立康唑的血药浓度，并应用于临床中伏立康唑用药监测，以促进其个体化用药。方法：色谱柱：Kromasil C₁₈（4.6 mm×150 mm，5 μm），柱温：35℃，流速：1.0 mL·min^-1，流动相：甲醇-水（60：40），检测波长：257 nm，内标：酮康唑。对该方法进行方法学验证。结果：该方法专属性良好，血浆中伏立康唑在0.1~20.0 μg·mL^-1范围内线性良好（r=0.999 6），定量下限为0.1 μg·mL^-1。高、中、低3个浓度提取回收率分别为（90.68±10.32）%、（92.82±8.26）%、（97.47±4.58）%；日内精密度RSD分别为5.87%、7.85%、4.10%；日间精密度RSD分别为5.64%、3.30%、2.74%。对某院20例（男12例，女8例）使用伏立康唑抗真菌治疗的患者运用该方法进行了监测，结果显示浓度范围在0.71~13.51 μg·mL^-1之间。结论：本方法专属性高，操作简便，结果准确，可用于临床上伏立康唑血药浓度的检测，从而促进其个体化用药的推广。
