ABSTRACT
Objective:To analyze the setup basis and registration rules of the practice scope of physicians in China, and take into account the current situation of individual provinces, for suggestions on further revision of the practice scope of these physicians.Methods:Relevant documents on practice scope setup were retrieved from such databases as CNKI, Wanfang and Weipu databases, while relevant national policies, laws and regulations were reviewed. On-site visits were conducted to health committees and medical institutions in 7 provinces from June 2020 through December 2020. Seminars and special interviews were held with relevant management personnel and doctors of different positions, for the purpose of learning the current physician practice scope setup and their suggestions for reform. Data gained from the above methods were summarized to arrive at reform suggestions for optimizing China′s practice scope setup, with further improvement made based on expert consultation method.Results:Several setbacks were found in the setup of their practice scope in China, namely as unclear setup principles, generalized setup of the national standards, inconsistent setup standards among the provinces, prohibition of cross-category registration, and roadblocks against in changing scope of practice. As the setup of the practice scope should set free manpower, unleash vitality, and delegate power, the practice scope should be changed to three categories of " discipline" , " discipline+ technology" and " comprehensive" . Physicians should be entitled to register separately as " discipline" and " discipline+ technology" as their practice scope, with " comprehensive" practice scope approved by a simple procedure of a notice.Conclusions:The setup and modification of the practice scope should be in a general rather than detailed manner, and conducive to the development of related disciplines. Such measures should also fully unleash the vitality of Chinese physicians, and take into account of both peacetime and emergencies, and both medical service and prevention.
ABSTRACT
Objective:To study the current setup of diagnosis and treatment subjects in China and make reform suggestions in light of existing problems.Methods:Relevant documents on medical institutions′ diagnosis and treatment subjects setup were retrieved from such databases as CNKI, Wanfang and Weipu database, while relevant national policies, laws and regulations were reviewed. On-site visits were conducted to health committees and medical institutions in 7 provinces from June 2020 through December 2020. Seminars and special interviews were held with relevant management personnel and doctors of different positions, for the purpose of learning the current medical institutions′ diagnosis and treatment subjects and their suggestions for reform. Data gained from the above methods were summarized to arrive at reform suggestions for optimizing China′s medical institutions′ diagnosis and treatment subjects, with further improvement made based on expert consultation method.Results:Problems found focus on such areas as inconsistent setup standards for medical treatment subjects, multiple overlapping services, and unclear numbering rules. Based on the disease list and skill list of the DRG system, a novel diagnosis and treatment subject setup method guided by service items could be established. Otherwise, the numbering and categories could changed on the current basis to correct existing problems. The subjects could be divided into such five categories as clinical, oral, traditional Chinese medicine, medical technology, and comprehensive, with level-1 and level-2 subjects set up respectively.Conclusions:In terms of subject functions, the setup of diagnosis and treatment subjects should be regularly adjusted or filed, instead of complete equivalence with administratively licensed subjects. As the current setup of diagnosis and treatment subjects had been in place for years, and had become key references for the department setup and performance appraisal of medical institutions, it was proposed to make adjustment on the current basis for the purpose of correcting existing problems.
ABSTRACT
Objective:To evaluate the comprehensive strength of the specialties included in the medical service capacity improvement project of Henan provincial medical and health institutions, analyze the influencing factors, and provide scientific basis for the specialty construction.Methods:A total of 52 specialties were included in the project. According to the content of construction assessment and acceptance, the questionnaire was designed and filled in by the persons in charge of the specialties from the aspects of basic conditions, medical technical team, medical service ability, medical quality, scientific research and teaching ability. TOPSIS method was used to evaluate the comprehensive strength of specialty, and the main influencing factors were analyzed by single factor analysis, Mann-Whitney U test, correlation analysis and multiple stepwise regression analysis. Results:The research and teaching ability of the specialties had the strongest correlation with the comprehensive strength of the specialties. The scientific research and teaching ability was strongly related to the medical service ability. The number of people holding the post of academic institutes at or above provincial level, the number of industry standards or national guidelines, the number of academic conferences hosted at or above the provincial level, the number of postgraduate training, the number of papers published in SCI and core journals were the main influencing factors of scientific research and teaching ability.Conclusions:It is necessary to improve the level of scientific research and teaching in key specialty to promote the improvement of medical service ability. We should pay more attention to the construction of high-level talents, the cultivation of research-oriented talents, the application of new medical technology and original research.

ABSTRACT
Exoskeleton nursing robot is a typical human-machine co-drive system. To full play the subjective control and action orientation of human, it is necessary to comprehensively analyze exoskeleton wearer's surface electromyography (EMG) in the process of moving patients, especially identifying the spatial distribution and internal relationship of the EMG information. Aiming at the location of electrodes and internal relation between EMG channels, the complex muscle system at the upper limb was abstracted as a muscle functional network. Firstly, the correlation characteristics were analyzed among EMG channels of the upper limb using the mutual information method, so that the muscle function network was established. Secondly, by calculating the characteristic index of network node, the features of muscle function network were analyzed for different movements. Finally, the node contraction method was applied to determine the key muscle group that reflected the intention of wearer's movement, and the characteristics of muscle function network were analyzed in each stage of moving patients. Experimental results showed that the location of the myoelectric collection could be determined quickly and efficiently, and also various stages of the moving process could effectively be distinguished using the muscle functional network with the key muscle groups. This study provides new ideas and methods to decode the relationship between neural controls of upper limb and physical motion.

Objective To evaluate the role of calcineurin ( CaN)/nuclear factor of activated T cell cytoplasmic 4 protein ( NFATc4) signaling pathway in inflammatory responses in lung tissues of rats with ventilator-induced lung injury ( VILI) . Methods Twenty-four clean-grade healthy male Wistar rats, aged 5-8 weeks, weighing 220-250 g, were divided into 3 groups ( n=8 each) using a random number table method: control C (group C), VILI group and cyclosporine A plus VILI group (group CsA+VILI). The animals were anesthetized with pentobarbital and tracheostomized. The rats were mechanically ventilated for 6 h with the tidal volume set at 40 ml/kg and respiratory rate at 40 breaths/min to establish the model of VI-LI. The rats kept spontaneous breathing in group C. CaN specific inhibitor cyclosporine A 10 mg/kg was in-traperitoneally injected at 1 h before ventilation in group CsA+VILI. Rats were sacrificed immediately after ventilation, lung tissues were obtained and stained with hematoxylin and eosin to evaluate lung injury, broncho-alveolar lavage fluid was collected for determination of tumor necrosis factor-alpha ( TNF-α) , inter-leukin-1beta ( IL-1β) and IL-6 concentrations by enzyme-linked immunosorbent assay, and the lungs were removed for determination of the wet to dry weight ratio ( W/D ratio) , expression of intercellular adhesion molecule-1 ( ICAM-1) and vascular cell adhesion molecule-1 ( VCAM-1) ( by real-time polymerase chain reaction) , and expression of calcineurin and NFATc4 in lung tissues ( using Western blot ) . Results Compared with group C, the W/D ratio, lung injury scores and concentrations of IL-1β, IL-6 and TNF-αin BALF were significantly increased, and the expression of CaN, NFATc4, ICAM-1 mRNA and VCAM-1 mRNA was up-regulated in group VILI ( P＜0. 05) . Compared with group VILI, the W/D ratio, lung injury scores and concentrations of IL-1β, IL-6 and TNF-αin BALF were significantly decreased, and the expres-sion of CaN, NFATc4, ICAM-1 mRNA and VCAM-1 mRNA was down-regulated in group CsA+VILI ( P＜0. 05) . Conclusion CaN/NFATc4 signaling pathway mediates inflammatory responses in lung tissues of rats with VILI.
ABSTRACT
Objective To investigate the appropriate method in diagnosing precursor lesions of pancreatic cancer and its treatment. Methods From Jan. 2006 to Dec. 2007, 92 cases were operated for pancreatic neoplasms. Among them 7 cases had pancreatic precursors. The mucinous cystic neoplasm was found in 1 case, intraductal papillary mucinous neoplasm(IPMN) in 2 cases, endocrine tumor in 1 case and pancreatic intraepithelial neoplasia (PanIN) in 3 cases. CA19-9 level was tested by immunoflucence assay. All of the 7 patients were examined by CT. Endoscopic ultrasound(EUS) and endoscopic retrograde cholangio-pancreatography examinations were performed on 1 and 2 patients respectively. Results There was neither specific symptom related to these precursors nor any evidence of mass as revealed by CT or ultrasound. But dilatation and stricture of pancreatic duct were found in PanIN patients, and cystic dilatation of pancreatic duct in pancreatic head was present more in IPMN patients. For cystic neoplasms in pancreatic body and tail, they were commonly solid and isolated. CA19-9 level was slightly elevated in some patients but with no diagnostic value. Surgical resection was done with excellent result. Conclusion For the suspected pancreatic precursors, aggressive diagnostic approach and surgical resection will be the best option and can further prevent cancer development.
