ObjectiveTo investigate the intervention effect of Buzhong Yiqitang （BZYQT） on pulmonary inflammation in mice induced by chronic intermittent hypoxia （CIH） and preliminarily elucidate its mechanism. MethodForty healthy male C57BL/6 mice aged 6-8 weeks were randomly divided into the following groups： normoxia group， model group （exposed to CIH）， and low-， medium-， and high-dose BZYQT groups. The normoxia group was exposed to a normoxic environment， while the model group and the low-， medium-， and high-dose BZYQT groups were exposed to intermittent hypoxia. In the BZYQT groups， the BZYQT （8.1， 16.2， 32.4 g·kg^-1·d^-1） was administered orally 30 min before placing the mice in the hypoxic chamber， while the model group and the normoxia group received an equivalent volume of normal saline. After five weeks of modeling， pulmonary function of the mice was measured using an EMKA animal lung function analyzer， and lung tissue samples were collected after the pulmonary function tests. Hematoxylin-eosin （HE） staining was performed to observe the histopathological changes in the lung tissue of each group. Enzyme-linked immunosorbent assay （ELISA） was used to measure the levels of interleukin-6 （IL-6）， interleukin-8 （IL-8）， tumor necrosis factor-α （TNF-α） in the serum， as well as angiotensin Ⅱ （Ang Ⅱ） and angiotensin-（1-7） ［Ang（1-7）］ in lung tissue. Western blot and immunohistochemistry were used to detect the protein expression of IL-6， IL-8， TNF-α， angiotensin-converting enzyme 2 （ACE2）， and mitochondrial assembly receptor （Mas）. ResultCompared with the normoxia group， the model group showed significant abnormalities in lung function （P<0.05， P<0.01）， lung tissue changes， such as thickening of alveolar walls and inflammatory cell infiltration， increased levels of IL-6， IL-8， TNF-α in the serum and Ang Ⅱ in lung tissue （P<0.01）， decreased level of Ang（1-7） （P<0.01）， increased protein expression of IL-6， IL-8， and TNF-α， and decreased protein expression of ACE2 and Mas （P<0.05， P<0.01）. Compared with the model group， the BZYQT groups showed improvement in lung function （P<0.05， P<0.01）， and HE staining of lung tissue showed approximately normal alveolar wall thickness and reduced inflammatory cell infiltration. Immunohistochemistry and Western blot analysis showed a significant decrease in the expression of inflammatory-related proteins （P<0.05， P<0.01）， and a significant increase in ACE2 and Mas protein expression （P<0.05， P<0.01）. ConclusionBZYQT can improve lung injury in mice exposed to CIH by regulating the ACE2-Ang（1-7）-Mas axis to inhibit inflammatory responses.

Vietnam,as an important country along the "one belt and one road",is closely related to China.Chinese traditional medicine has entered Vietnam and gained strong support from policy and public recognition.It has a good foundation for development and a bright future.Based on the current situation of traditional Chinese medicine exchanges between China and Vietnam and Vietnam's basic national conditions,the author puts forward that exploring new cooperative models through multi-level cooperative projects,which relys on the role of the Chinese Chamber of Commerce,and adheres to the complementary promotion between trade in services and trade in goods.They are the feasible ways for Chinese medicine to develop in Vietnam.The development of Chinese medicine in Vietnam needs the adherance to the four principles of bidirectional positioning,suiting measures to local conditions,standardizing standards and risk prevention.

Objective To explore the application effect of PDCA cycles on the normal limb position of stroke patients with hemiplegia. Methods The stroke patients with hemiplegia (128 cases) were selected as study subjects. Patients(62 cases)during January to September 2014 were set as the control group,and received routine nursing care. Patients(66 cases)during October 2014 to July 2015 were set as the experimental group,and used PDCA cycles management on the normal limb position additionally. The application effect of PDCA cycles on the normal limb position was evaluated through comparing two groups with qualification rates of normal limb position and incidence of complications. Results The qualification rates of normal limb position in the control group was 38.71%(24/62), which was higher than that of the control group, which was 75.76% (50/66) (χ2=16.504, P<0.01). The complications occurred in the control group were strephenopodia (11 cases), foot drop (16 cases), dislocation of shoulder (9 cases), omodynia (27 cases) and myospasm (34 cases), and they were 3 cases, 7 cases, 2 cases, 15 cases and 18 cases in the experimental group respectively. The incidence of complications was lower than those of the control group (χ2=4.001-8.961, P < 0.05), and the difference was statistically significant between two groups. Conclusions PDCA cycles management could improve the qualification rates of normal limb position and reduce the incidence of complications, which was beneficial to the recovery of limb function.
