In order to explore the feasibility of planting sweet sorghum in sugarcane growing area to prolong milling duration for bioethanol production, 15 varieties were sown monthly from March to September in Liuzhou of Central Guangxi Zhuang Autonomous Region. Yields of fresh stem, grain and leave were documented. The results showed that all varieties grew well when sown from March to August, but could not get mature when sown after late September. The high fresh stem yields were observed for the varieties Sart and PT3-S, 79.28 t/hm2 and 78.58 t/hm2 for single growing season, and 157.95 t/hm2 and 155.25 t/hm2 for two growing seasons. Ripening began from the end of June to late December, making the feed stock available for ethanol production from July to the end of December, even January next year.

A case of a 69-year-old female patient, with cough, expectoration, chest tightness and shortness of breath for 10 days accompanied by left pleural effusion, was reported. Initially, a large number of suspected malignant lymphoma cells were found in the patient′s pleural effusion through routine cell morphological examination after admission, which was the direction of clinical diagnosis and treatment in the next step. Then the patient was diagnosed as primary pulmonary diffuse large B-cell lymphoma (DLBCL) through imaging, bone marrow and lung biopsy pathology. Finally, the patient was treated effectively with R-CHOP regimen, but she died of respiratory failure 9 weeks later, because she did not receive regular follow-up and treatment after the sixth chemotherapy cycle. Primary pulmonary DLBCL, an extremely rare extranodal lymphoma' lacks specificity clinical manifestations and is easy to be missed and misdiagnosed. DLBCL with a large number of malignant pleural effusion progresses rapidly and has a poor prognosis. The routine cell morphology examination of pleural effusion is simple and intuitive, which can capture key information in the shortest time, preliminarily provide clinical diagnosis and treatment ideas, and provide accurate basis for disease diagnosis.
