A 22-year-old Chinese man presented with fever, cough,
hoarseness, neck pain, acute heart failure and hemoptysis. Pulmonary
tuberculosis was proved by sputum culture. Chest imaging showed an aortic arch
pseudoaneurysm and bilateral ground glass opacities. Echocardiography confirmed
cardiomyopathy. With anti-TB drugs, high-dose prednisone and surgery, the life
of this patient was successfully prolonged for more than four months. The concomitant
disorders of aortic pseudoaneurysm, alveolar hemorrhage and cardiomyopathy in
pulmonary tuberculosis are intriguing. We postulate that immune-mediated small
vessel vasculitis triggered by pathogens plays an important role in the
pathogenesis of this disease, rather than a direct TB infection.
In water deficit area, judicious use of water is essential for increasing
area under crop production with limited water supply. Film Mulching has been
advocated as an effective means for conserving soil moisture in rice
production. The effects of high density polyethylene (HDPE) film on increasing
rice production, controlling weeds and residue amount of plastic were studied
under five treatments, including 5, 10, 15 and 20 μm thickness as well as bare
cultivation (CK). The results indicated that the HDPE film mulching mode had
significant effects on weed control, soil temperature, soil moisture,
photosynthetic rate, seedling biomass, yield and residues of plastic film.
Combined with economic effect, it showed that the HDPE film of 10 μm is the
best option for rice production.
