β-Thalassemia (β-thal) is a common hematological disorder in the Guangxi Zhuang Autonomous Region of Southern China. Heterozygous β-thal is usually associated with reduced hematological indices and increased Hb A2 levels. However, the preventive program of the regional government only conducts the screening of hematological indices [complete blood count (CBC)] especially at primary hospitals. In this study, we describe a male β-thal patient presenting normal hematological indices but with a high Hb A2 level. We proposed that hemoglobin (Hb) analysis and CBC should be performed together in the preventive screening program in regions with a high thalassemia incidence to avoid misdiagnosis.

[Objective]The varieties of processing high-quality tea flowers were screened and supporting processing technology was studied in order to provide references for better development of tea flowers in the future. [Method]Dried flowers varieties were screened through sensory quality evaluation. The effects of different drying temperature and withering time on tea flower quality and main biochemical components were studied to determine its optimum processing parameters. [Result]There are several major tea plants in Guangxi suitable for producing high quality flower tea such as Liubaocha, Nanshan-baimaocha, Taicha12, Baxiancha, Lingyun-baimaocha, Fuyun 6, Guiping-xishancha, Fengqing-dayecha and Longsheng-longjicha. Liubaocha, Nanshan-baimaocha and Taicha12 were good sources for great-flavor dried flower. Longsheng-longjicha and Baxiancha were good sources for elegant dried flower. Fuyun 6, Guiping-xishancha and Fengqing-dayecha were good sources for fragrant dried flower. The best tea flowers were produced under natural withering for 6.0 h and drying for 2.0 h at 90 °C after microwave fixation. [Conclusion]The quality among the main cultivated tea varieties vary a lot, hence different styles of dried tea flower can be produced based on individual quality. Drying temperate and withering time, two key factors in processing quality, should be regarded as top priorities. [ABSTRACT FROM AUTHOR]
