Objective To investigate the correlation between serum level of gamma-glutamyl transferase (GGT) and coronary heart disease (CHD) in military pilots. Methods Sixty male military pilots hospitalized in Airforce General Hospital having coronary angiography examination(CAG) from March 2005 to May 2015 were involved then were divided into CHD group (n = 24) and control group (n = 36) according to the results of coronary angiography (CAG). The patients with CHD were divided into low score group (Gensini score ≤ 20) and high score group (Gensini score > 20) according to Gensini score. Results There were significant increase of the level of TG, GGT and decrease of the level of HDL-C in CHD group than those in control group(P<0.05);there was no significant difference with the level of GTT between high score group and low score group (P > 0.05); logistic regression analysis showed that serum GGT was an independent risk factor of CHD in military pilots (OR = 1.168, P < 0.01). Conclusion Serum GGT is associated with CHD in military pilots and is the independent risk factor of CHD in the pilots.

At present, most of the common medical clothes in clinic are uniform medical clothes, but there is no special clothes for patients in intensive care unit (ICU). In recent years, with the extensive application of critical ultrasound in the field of critical medicine, it is obviously difficult to meet the clinical needs on traditional patients' clothes. Guangdong Provincial People's Hospital designed a patient's clothing for critical ultrasound examination. The left/right chest, lateral chest, groin and abdomen of the patient's clothing body were covered with cloth and marked areas. When critically ill patients need to be examined by ultrasound and electrocardiogram, the site can be quickly located only by removing the cloth. At the same time, it can protect patients' privacy, avoid aggravating the condition due to cold, increase patients' comfort in clothing, and also facilitate medical care. It is worthy popularizing in clinic because of its practicability and novel design.

Since 2010, the incidence of severe fever with thrombocytopenia syndrome (SFTS) has been increased. Owing the progress in diagnosis and treatment, the overall mortality of SFTS in China has decreased, while the mortality in critical SFTS patients is still high. In order to provide guidance and working procedures for clinicians to diagnose and treat critical SFTS, the National Medical Center for Major Public Health Events invited experts to discuss and formulate this consensus based on their experience and up-to-date knowledge on SFTS.

Artemisia annua is the main natural source of artemisinin production. In A. annua, extended drought stress severely reduces its biomass and artemisinin production while short-term water-withholding or abscisic acid (ABA) treatment can increase artemisinin biosynthesis. ABA-responsive transcription factor AabZIP1 and JA signaling AaMYC2 have been shown in separate studies to promote artemisinin production by targeting several artemisinin biosynthesis genes. Here, we found AabZIP1 promote the expression of multiple artemisinin biosynthesis genes including AaDBR2 and AaALDH1, which AabZIP1 does not directly activate. Subsequently, it was found that AabZIP1 up-regulates AaMYC2 expression through direct binding to its promoter, and that AaMYC2 binds to the promoter of AaALDH1 to activate its transcription. In addition, AabZIP1 directly transactivates wax biosynthesis genes AaCER1 and AaCYP86A1. The biosynthesis of artemisinin and cuticular wax and the tolerance of drought stress were significantly increased by AabZIP1 overexpression, whereas they were significantly decreased in RNAi-AabZIP1 plants. Collectively, we have uncovered the AabZIP1-AaMYC2 transcriptional module as a point of cross-talk between ABA and JA signaling in artemisinin biosynthesis, which may have general implications. We have also identified AabZIP1 as a promising candidate gene for the development of A. annua plants with high artemisinin content and drought tolerance in metabolic engineering breeding.
