Objective: To study the etiology, clinical manifestation, diagnosis, treatment and precaution of pulmonary embolism following major surgery of gastrointestinal malignant tumors. Methods: Thirty-two cases of pulmonary embolism following major surgery of gastrointestinal malignant tumors were analyzed retrospectively. Results: The most common clinical manifestations were dyspnea, thoracodynia and palpitation. The D-dimer of all cases was positive. The examination of pulmonary arteriography by spiral computed tomography might assist the diagnosis of the disease. Twenty-two patients were discharged through the treatment of oxygen therapy and anticoagulation. Six patients recovered through the treatment of assisted respiration by respirator, thrombolysis and anticoagulation. Four patients died of respiratory failure. Conclusion: The operation of gastrointestinal malignant tumors can increase the incidence of pulmonary embolism. Arteriography by spiral computed tomography and D-dimer can assist the diagnosis and thrombolysis and anticoagulation were effectivel for the treatment.

With esoterica of Infantile Tuina by LI Dexiu and Infantile Tuina Therapy of LIU Kaiyun, the differences and similarities of manipulations, acupoints and the principles of treatment were studied so as to provide theoretical evidence to popularize tuina of LI Dexiu and LIU Kaiyun.

Lignocellulosic biomass represents an abundant, low-cost and renewable source of potentially fermentable sugars. It is acandidate besides petroleum as feedstock for fuel and chemical production. Recent researches on utilizing lignocellulosicsas feedstock boost development of numerous-promising processes for a variety of fuels and chemicals, such as biodiesel, biohydrogen and ethanol. However, high cost in depolymerization is a primary obstacle preventing the use of lignocellulosic biomass as feedstock. Consolidated bioprocessing (CBP), refers to the bioprocess without any exogenous cellulolyotic enzymes added, converting the lignocellulosic material into biochemicals directly, which could potentially avoid the cost of the dedicated enzyme generation step by incorporating enzyme-generating, biomass-degrading and bioproduct-producing capabilities into a single organism through genetic engineering. There are two CBP strategies, native strategy and recombinant strategy. We mainly introduce the recombinant strategy, including its principle, the two responding styles, the contributions of synthetic biology and metabolic engineering and the future challenges.
