ABSTRACT
Aiming at the human-computer interaction problem during the movement of the rehabilitation exoskeleton robot, this paper proposes an adaptive human-computer interaction control method based on real-time monitoring of human muscle state. Considering the efficiency of patient health monitoring and rehabilitation training, a new fatigue assessment algorithm was proposed. The method fully combined the human neuromuscular model, and used the relationship between the model parameter changes and the muscle state to achieve the classification of muscle fatigue state on the premise of ensuring the accuracy of the fatigue trend. In order to ensure the safety of human-computer interaction, a variable impedance control algorithm with this algorithm as the supervision link was proposed. On the basis of not adding redundant sensors, the evaluation algorithm was used as the perceptual decision-making link of the control system to monitor the muscle state in real time and carry out the robot control of fault-tolerant mechanism decision-making, so as to achieve the purpose of improving wearing comfort and improving the efficiency of rehabilitation training. Experiments show that the proposed human-computer interaction control method is effective and universal, and has broad application prospects.

In response to the problem that the traditional lower limb rehabilitation scale assessment method is time-consuming and difficult to use in exoskeleton rehabilitation training, this paper proposes a quantitative assessment method for lower limb walking ability based on lower limb exoskeleton robot training with multimodal synergistic information fusion. The method significantly improves the efficiency and reliability of the rehabilitation assessment process by introducing quantitative synergistic indicators fusing electrophysiological and kinematic level information. First, electromyographic and kinematic data of the lower extremity were collected from subjects trained to walk wearing an exoskeleton. Then, based on muscle synergy theory, a synergistic quantification algorithm was used to construct synergistic index features of electromyography and kinematics. Finally, the electrophysiological and kinematic level information was fused to build a modal feature fusion model and output the lower limb motor function score. The experimental results showed that the correlation coefficients of the constructed synergistic features of electromyography and kinematics with the clinical scale were 0.799 and 0.825, respectively. The results of the fused synergistic features in the K-nearest neighbor (KNN) model yielded higher correlation coefficients ( r = 0.921, P < 0.01). This method can modify the rehabilitation training mode of the exoskeleton robot according to the assessment results, which provides a basis for the synchronized assessment-training mode of "human in the loop" and provides a potential method for remote rehabilitation training and assessment of the lower extremity.

ABSTRACT
Objective:Understand the perceptions of research integrity and their attitudes to related integrity violations among newly recruited researchers in a tertiary hospital.Methods:The electronic questionnaire was distributed to a WeChat group of 123 newly recruited researchers in a tertiary hospital in 2018. The questionnaire included the demographic characteristics, the awareness of research integrity and attitude towards behaviors that violate research integrity.Results:The total number of respondents was 87 and 45.98% respondents received research integrity training. Less than 50% of respondents were familiar with the regulatory requirement of research integrity, the definition of research integrity, fabrication, falsification, plagiarism and other common problems violating research integrity. Regarding attitude towards scientific misconduct, most investigators (82.76%~90.8%) thought it incorrect. 64.37% of investigators would like to report to regulatory authorities if they found scientific misconduct. If the researchers strongly violated research integrity, 80.46%~81.61% of respondents voted for suspending his or her promotion, suspending his or her application for being a mentor and 58.62% of respondents voted for being banned for conducting any research forever. Receiving education of research integrity is an independent influence factor of awareness of fabrication, falsification and plagiarism (FFP).Conclusions:The proportion of newly recruited researchers receiving research integrity training in tertiary hospital is not big and most researchers don't know much about research integrity. Their attitudes to academic misconduct need to be further strengthened. Various measures are urgently needed to carry out to improve the integrity awareness and attitude of newly recruited researchers in tertiary hospitals.

ABSTRACT
Objective: To research the effect of traditional Chinese medicine compound Chaijie Yiganxian (CJYGX) on the hepatic fibrosis in rats and explore the mechanism. Method: Totally 60 SD rats were randomly divided into normal group, model group, positive group (Biejia Jianwan), and low, medium and high-dose CJYGX groups. Except for the normal group, the remaining five groups were involved in establishing the hepatic fibrosis model through the intraperitoneal injection of thioacetamide (TAA). Fourth weeks after modeling, the positive group was given Biejiajian pill (1 g·kg-1·d-1), and high, medium and low-dose CJYGX groups were given CJYGX(7.96, 3.98, 1.99 g·kg-1·d-1), respectively. The model group was given normal saline once a day for 5 weeks. 24 h after the last intragastric administration with chloral hydrate, the rats were anesthetized slightly. Serum and liver tissues were collected. The liver wet weight was weighed electronically, and the liver index was calculated. Liver function indexes[alanine transaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP)] and serum markers[laminin (LN), hyaluronidase (HA), Ⅳ collagen (CⅣ), procollagen Ⅲ (PCⅢ)] of hepatic fibrosis were detected by enzyme linked immunosorbent assay (ELISA). The degree of hepatic fibrosis by Masson stain, mRNA expressions of transforming growth factor-β1 (TGF-β1), Smad2, Smad3, Smad4, Smad7 were detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and protein expression levels of platelet derived growth factor (PDGF), TGF-β1 and α-smooth muscle actin (α-SMA) were detected by immunohistochemical or Western blot. Result: Compared with the blank group, the model group liver index was significantly increased; the contents of ALP, AST and ALT were significantly increased; the liver fibrosis indexes LN, HA, Ⅳ-C, PCⅢ and HYP were significantly increased; the degree of liver fibrosis was significantly increased in Masson tissue; the mRNA expressions of TGF-β1, Smad2, Smad3, Smad4 were significantly increased; and the Smad7 mRNA expression was significantly decreased. The protein expressions of TGF-β1, PDGF and α-SMA increased significantly (Pβ1, Smad2, Smad3, Smad4 and up-regulate mRNA expression of Smad7.Immunohistochemical and Western blot analysis show that, compared with model group, CJYGX could significantly reduce the protein expressions of TGF-β1, PDGF and α-SMA (PPConclusion: Traditional Chinese medicine compound CJYGX may protect TAA-induced hepatic fibrosis injury by interfering with TGF-β1/Smad signaling pathway.

ABSTRACT
Rabies remains a continuous threat to public health in Beijing. In this study, a total of 224 brain tissues were collected from suspected infected stray dogs within Beijing between January 2015 and December 2016. Among them, total of 67 samples were diagnosed positive for rabies. In the phylogenetic analysis, rabies in Beijing is currently a relatively independent public health issue originating from local rabid dogs apart from the imported cases from elsewhere in the country. Because vaccination of unregistered dogs against rabies is still neglected in Beijing and other regions of China, national and local authorities should play central roles in all related aspects, such as development of policies, engagement of stakeholders for public and professional education, entire vaccination process, and animal management.
