OBJECTIVE: To observe the effect of electroacupuncture (EA) on the intestinal flora in rats with chronic obstructive pulmonary disease (COPD) and explore its possible mechanism based on the gut-lung axis theory. METHODS: A total of 30 male SD rats of SPF grade were randomly divided into a normal control (NC) group, a model group and an EA group, 10 rats in each one. In the model group and the EA group, COPD model was established by intratracheal instillation of lipopolysaccharide combined with cigarette fumigation. In the EA group, EA was applied at bilateral "Feishu" (BL13) and "Zusanli" (ST36), with disperse-dense waves, in frequency of 4 Hz/20 Hz, current of 1-3 mA, 20 min a time, once a day for 14 days continuously. Before and after modeling, as well as after intervention, body weight was observed; after intervention, the lung function indexes (forced expiratory volume in 0.1 second [FEV_0.1], FEV_0.1/forced vital capacity [FVC]%, forced expiratory volume in 0.3 second [FEV_0.3] and FEV_0.3/FVC%) were measured, serum levels of inflammatory factors (tumor necrosis factor-α[TNF-α], interleukin-6[IL-6], interleukin-1β[IL-1β] and interleukin-10[IL-10]) were detected by ELISA, histopathology of lung and colon tissues was observed by HE staining, the intestinal flora were analyzed by 16S rRNA, and the correlations between lung function and intestinal flora were analyzed. RESULTS: Compared with the NC group, in the COPD group, the body weight and lung function indexes were reduced (P<0.01); the lung and colon tissues were damaged, the mean linear intercept (MLI) of alveolus and inflammatory cell numbers of 100 μm² in lung tissue were increased (P<0.01); the serum levels of TNF-α, IL-6 and IL-1β were increased (P<0.01, P<0.05), and the serum level of IL-10 was decreased (P<0.01); α-diversity indexes of intestinal flora were increased (P<0.01); the relative abundance of Bacteroidetes, Proteobacteria and Oscillospira, Bacteroides, Coprococcus was increased (P<0.01), the relative abundance of Firmicutes, Actinobacteria, Tenericutes, TM7 and Lactobacillus, Allobaculum, Bifidobacterium, YRC22 was decreased (P<0.01, P<0.05); 31 different expressed metabolic pathways were identified between the two groups. Compared with the COPD group, in the EA group, the body weight and lung function indexes were increased (P<0.01); the damage of lung and colon tissues was improved, the MLI of alveolus was decreased (P<0.05); the serum levels of TNF-α, IL-6 and IL-1β were decreased (P<0.05), and the serum level of IL-10 was increased (P<0.05); α-diversity indexes of intestinal flora were decreased (P<0.01); the relative abundance of Bacteroidetes, Proteobacteria and Oscillospira, Bacteroides, Coprococcus was decreased (P<0.01, P<0.05), the relative abundance of Firmicutes, Actinobacteria, Tenericutes, TM7 and Lactobacillus, Allobaculum, Bifidobacterium, YRC22 was increased (P<0.01); 35 different expressed metabolic pathways were identified between the two groups. The lung function was positive related with Actinobacteria, Tenericutes, TM7 and YRC22, and was negative related with Bacteroidetes, Proteobacteria and Oscillospira, Bacteroides, Coprococcus. CONCLUSION EA may ameliorate lung function and tissue injury of COPD by regulating intestinal flora dysbiosis and inflammatory response, suggesting an anti-inflammatory effect mediated via "gut-lung" axis.

Combining the knowledge of traditional Chinese medicine and modern medicine on glucolipid metabolism disorders， it is believed that the formation process of glycolipid metabolism disorders can be presented as five states "depression， phlegm-dampness， heat， blood stasis， and deficiency"， and the turbid pathogens run through the whole process. Accordingly， the method of "regulating states and removing turbidity" is proposed， which is specifically the method of resolving depression and turbidity， dispelling phlegm-dampness and turbidity， clearing heat and turbidity， dispelling blood stasis and turbidity， and replenishing deficiency and removing turbidity. Combined with the biological basis of glycolipid metabolism disorder， through the analysis of the clinical application of each method and the related mechanism of action， it is clarified that the method of regulating states and resolving turbidity can play a role in improving glycolipid metabolism disorder by regulating lipid metabolism disorder， insulin resistance， bile acid metabolism abnormality， intestinal bacterial flora， and its metabolite abnormality and other mechanisms of action.

Objective To clarify the bottlenecks in the technology transfer work of public hospitals in China,and try to propose work optimization strategies and suggestions from the perspectives of different stakeholders.Methods The relevant literature about the transformation of scientific and technological achievements in public hospitals was searched on CNKI,and inductively summarize the relevant concepts and categories through the three stages of grounded theory coding.Results Through the three stages of coding,85 initial concepts,29 categories,and 5 main categories were sorted out,and a model attributing the influencing factors of the transformation of scientific and technological achievements in public hospitals was constructed,involving five major entities:public hospitals,medi-cal staff,enterprises,government,and universities.Conclusion The work of transforming scientific and technologi-cal achievements in public hospitals involves multiple stakeholders.It can start from the standardized management of public hospitals,the technological breakthroughs of medical staff,the active leadership of the government,the pro-active integration of enterprises,and the talent cultivation of universities to achieve innovation in talent cultivation mechanisms,industry evaluation mechanisms,profit distribution mechanisms,and intelligent management mecha-nisms.

Objective Understanding the cognitive attitude,influencing factors,and demand elements of medical staff in public hospitals towards the transformation of scientific and technological achievements,and proposing coun-termeasures and suggestions to improve the transformation rate of scientific and technological achievements in pub-lic hospitals.Methods Based on a questionnaire survey of the cognition and needs for the transformation of scientific and technological achievements among medical staff in public hospitals,it investigates medical personnel from 12 public hospitals in Anhui Province.Data processing is conducted using descriptive analysis and moderated mediation effect analysis methods.Results The cognitive attitude is positively correlated with influencing factors(r=0.125,P＜0.01),the degree of cognition is positively correlated with demand elements(r=0.599,P＜0.01),and influencing factors are positively correlated with demand elements(r=0.336,P＜0.01).The impact factors of medical staff in the process of scientific and technological achievement transformation play a partial mediating role between cognitive attitude and demand elements,and the technical title of medical staff has a moderating effect.Conclusion There are bottlenecks in the transformation of scientific and technological achievements by medical staff in public hospitals,in-cluding a weak awareness of transformation,limited transformation capabilities,disconnection between scientific re-search achievements and the market,and an unobvious collaborative effect of"government,education,medical care,production,and research".Public hospitals should improve supporting measures in aspects such as talent cultivation,management systems,professional training,and information construction.
