The near infrared （NIR） spectroscopy technique has been applied in many fields because of its advantages of simple preparation, fast response, and non-destructiveness. We investigated the potential of NIR spectroscopy in diffuse reflectance mode for determining the soluble solid content （SSC） and acidity （pH） of intact loquats. Two cultivars of loquats （Dahongpao and Jiajiaozhong） harvested from two orchards （Tangxi and Chun＇an, Zhejiang, China） were used for the measurement of NIR spectra between 800 and 2500 nm. A total of 400 loquats （100 samples of each cultivar from each orchard） were used in this study. Relationships between NIR spectra and SSC and acidity of loquats were evaluated using partial least square （PLS） method. Spectra preprocessing options included the first and second derivatives, multiple scatter correction （MSC）, and the standard normal variate （SNV）. Three separate spectral windows identified as full NIR （800-2500 nm）, short NIR （800-1100 rim）, and long NIR （1100-2500 nm） were studied in factorial combination with the preprocessing options. The models gave relatively good predictions of the SSC of loquats, with root mean square error of prediction （RMSEP） values of 1.21, 1.00, 0.965, and 1.16 °Brix for Tangxi-Dahongpao, Tangxi-Jiajiaozhong, Chun＇an-Dahongpao, and Chun＇an-Jiajiaozhong, respectively. The acidity prediction was not satisfactory, with the RMSEP of 0.382, 0.194, 0.388, and 0.361 for the above four loquats, respectively. The results indicate that NIR diffuse reflectance spectroscopy can be used to predict the SSC and acidity of loquat fruit.

应用近红外漫反射光谱定量分析技术对两个产地三个品种枇杷的可溶性固形物进行无损检测试验研究。通过分析，发现在波长1400～1500nm和1900～2000nm两段范围，样品的可溶性固形物与光谱吸光度之间的相关系数较高；用偏最小二乘回归PLSR、逐步多元线性回归SMLR和主成分回归PCR三种方法分别建立这两个波段和全波段范围的模型，全波段的PLSR模型的效果较优。研究发现一阶和二阶微分光谱建立的模型均不如原始光谱建立的模型效果好。最终建立三个品种枇杷样品的原始光谱在全波段范围经17点平滑后的PLSR模型，模型的校正集和预测集的相关系数分别为0．96和0．95。研究表明近红外光谱检测技术可用于枇杷可溶性固形物含量的定量分析。

目的了解2009年深圳市收治的30例甲型H1N1流行性感冒（流感）确诊病例的流行病学和临床特点。方法30例患者均经2次鼻拭子、咽拭子甲型H1N1流感病毒核酸检测阳性（RT—PCR法），此后每天检测病毒核酸直至连续2d均阴性。第1次病毒核酸检测阳性后立即开始奥司他韦（商品名为达菲）或“中药I号”抗病毒治疗，5d为一疗程。收集患者流行病学、临床和一般实验室资料。统计学处理采用t检验。结果29例患者为输人性病例，另1例为二代病例，系7个月女婴。发病平均年龄（20．42±12．59）岁，离开疫区至发病的平均时间为（53．33±53．08）h，其中2例离开疫区超过8d才发病，其密切接触人群中发现1例隐性感染者。30例患者均有发热，平均最高体温（38．40±0．80）℃，其他临床症状依次为咳嗽17例（56．7％）、流涕9例（30．0％）、咽痛9例（30．0％）、头痛7例（23．3％）、鼻塞2例（6．7％）、肌肉酸痛1例（3．3％）。22例患者在抗病毒治疗5d内病毒核酸转阴，8例在抗病毒治疗第6天或以后病毒核酸转阴。21例在病程7d内病毒核酸转阴，9例在起病后病毒核酸阳性持续8d或以上，后者较前者中性粒细胞计数明显下降，分别为（1．47±1．03）×10^9／L和（2．69±1．63）×10^9／L（t=2．06，P=0．048），血常规异常持续时间也明显延长，分别为（2．78±2．49）d和（0．71±1．31）d，差异有统计学意义（t=2．34，P=0．006）。结论甲型H1N1流感发病年龄偏低，临床症状不严重。部分病例潜伏期可能超过7d，病程7d或抗病毒治疗5d后仍有可能检出病毒，存在亚临床隐性感染的可能。血常规变化与病毒核酸阳性的持续时间存在一定关系。
