Research advance in wood composites in China

Wood composites can generally be classified in three parts: laminated composites, mixed composites and penetrated composites. Every part has its own characteristic and can be further divided. This paper introduces the history and the state of development of wood composites in China. The research about glue-laminated timber is rare and the industry hardly comes to being. A great of achievements have been obtained in mixed composites and it is well industrialized. Many studies on scrimber have been done and the Chinese researchers are looking for a feasible way to develop the scrimber industry in China. Chinese researchers also spent so much energy in studying wood plastic composites (WPC), but it has not been industrialized due to the high cost.

Research progress of integrated traditional Chinese and Western medicine in the treatment of advanced gastric cancer

Gastric cancer(GC)is a malignant tumor originating from the gastric epithelium,and its incidence and mortality rates rank third among all malignant tumors worldwide.It is also one of the most common cancers in China and is treated predominantly by Western medicine in clinical practice.However,with the advancements in medical technology and informatics,the values of traditional Chinese medicine(TCM)in preventing and treating GC and improving prognosis have increasingly been recognized.According to TCM,clinical manifestations of GC can be divided into Yege(dysphagia),regurgitation,stomach pain,and Zhengxia(abdominal mass).Due to the unbalanced distribution of health care resources in China,most GC patients already have progressive or advanced-stage disease at the first diagnosis.As a result,most GC patients have poor physical function,and surgery or chemotherapy alone will aggravate the impairment to the immune function and seriously affect the quality of life.In contrast,TCM therapies have shown promising efficacy in the management of these patients.Here we review the role of the integrated TCM and Western medicine in treating advanced GC.
