OBJECTIVETo study the effect of light quality on growth, polysaccharides content of Ganoderma lucidum.

METHODG. lucidum was planted under different light qualities. The growth of G. lucidum was observed and polysaccharides content was determined in different growth periods.

RESULTThere were significant differences in the form of the thickness and the numbers of ringed of the fruit before the ejection. The maximum content of G. lucidum polysaccharides under different light qualities were appeared in different periods. The content of polysaccharides was higher than that of CK under blue light in the period of budding, parachute phase, after spore ejection. The content of polysaccharides was increased under green light in the period of growth stage. The yield of fruits and spores were different in different light qualities.

CONCLUSIONThe light quality could increase the content of polysaccharides in G. lucidum.

OBJECTIVETo study the effect of light quality on growth, antioxidant enzyme activities of Ganoderma lucidum mycelium.

METHODG. lucidum mycelium was cultured under different light qualities by light emitting diodes (LED). The growth G. lucidum mycelium was observed and antioxidant enzyme activities was determined in different growth periods.

RESULTUnder the red LED, the blue LED and dark condition (CK), the mycelium grew faster than that under other light qualities. The white LED resulted in a largest increase in the amount of the mycelium and always kept the activities of CAT high level. Major fluctuations of POD activities emerged under the green LED, while enhanced severely in the late phase. Under the yellow LED, the activities of SOD appeared high level. However, SOD activities on dark (CK) raised obviously in late period. At the late stage, the content of mycelium polysaccharides was significant higher than that under the blue LED.

CONCLUSIONThe light quality could influence the growth and metabolism of G. lucidum mycelium.

Objective    To review and analyze the clinical manifestations of common aortitis in cardiac surgery. Methods    We screened 41 552 patients who were hospitalized in the Department of Cardiac Surgery of Zhongshan Hospital, Fudan University from 2010 to 2020, analyzed the patients' clinical data, and classified according to the type of diseases. Then we summarized all their clinical manifestations. Results    In our center 145 patients were operated for aortitis diseases, including 75 males and 70 females, with the age of 24-76 (45.6±11.3) years. There were 61 patients of Takayasu's arteritis, 51 patients of Behcet's disease, 8 patients of syphilitic aortitis, 8 patients of systemic lupus erythematosus, 2 patients of Kawasaki disease, 4 patients of ankylosing spondylitis, 10 patients of dry syndrome, and 1 patient of scleroderma. Conclusion    Aortitis is not uncommon in cardiac surgery, and awareness of the disease should be enhanced. So that we can distinguish various types of aortitis and to make proper management to improve patients' prognosis.
