The quality of moxa is an important factor affecting moxibustion therapy, and traditionally, 3-year moxa is considered optimal, although scientific data are lacking. This study focused on 1-year and 3-year moxa from Artemisia stolonifera and A. argyi(leaf-to-moxa ratio of 10∶1) as research objects. Scanning electron microscopy(SEM), Van Soest method, and simultaneous thermal analysis were used to investigate the differences in the combustion heat quality of 1-year and 3-year moxa and their influencing factors. The results showed that the combustion of A. stolonifera moxa exhibited a balanced heat release pattern. The 3-year moxa released a concentrated heat of 9 998.84 mJ·mg~(-1)(accounting for 54% of the total heat release) in the temperature range of 140-302 ℃, with a heat production efficiency of 122 mW·mg~(-1). It further released 7 512.51 mJ·mg~(-1)(accounting for 41% of the total heat release) in the temperature range of 302-519 ℃. The combustion of A. argyi moxa showed a rapid heat release pattern. The 3-year moxa released a heat of 16 695.28 mJ·mg~(-1)(accounting for 70% of the total heat release) in the temperature range of 140-311 ℃, with an instantaneous power output of 218 mW·mg~(-1). It further released 5 996.95 mJ·mg~(-1)(accounting for 25% of the total heat release) in the temperature range of 311-483 ℃. Combustion parameters such as-R_p,-R_v, D_i, C, and D_b indicated that the combustion heat quality of 3-year moxa was superior to that of 1-year moxa. It exhibited greater combustion heat, heat production efficiency, flammability, mild and sustained burning, and higher instantaneous combustion efficiency. This study utilized scientific data to demonstrate that A. stolonifera could be used as excellent moxa, and the quality of 3-year moxa surpassed that of 1-year moxa. The research results provide a scientific basis for the in-depth development of A. stolonifera moxa and the improvement of moxa quality standards.

Objectives:To systematically analyze the framework and contents of World Health Organization (WHO) policy and action strategies on rehabilitation using the theory of WHO health service components, to explore the theoretical bases, methodology, framework and core elements of WHO's international rehabilitation policy. Methods:WHO has launched rehabilitation-related policy documents, mainly including Rehabilitation in Health Systems, Rehabilitation in Health Systems: Guide for Action, Rehabilitation Indicator Menu: a tool accompanying the Framework for Rehabilitation Monitoring and Evaluation (FRAME), Template for Rehabilitation Information Collection (TRIC): a tool accompanying the Systematic Assessment of Rehabilitation Situation (STARS), and established systems of international rehabilitation policy architecture system. Using content analysis, this study analyzed in detail the theoretical basis and methodology of international rehabilitation policy, the policy framework, and the core elements of the action strategy and priority areas of rehabilitation service development in perspective of WHO six building blocks of health system, namely leadership and governance, financing, human resources for health, service delivery, medical technology, and health information systems. Results:WHO rehabilitation policy is developed based on WHO's theories of person-centered health services, social determinants of health, and functioning, disability and health of International Classification of Functioning, Disability and Health. WHO rehabilitation policy recognized that the development of rehabilitation was an important pathway achieving United Nations 2030 Sustainable Development Goals 3, ensure healthy lives and promote well-being for all at all ages, i.e. Unlversal Health Coverage. This paper systematically analyzed WHO's international policy framework, action strategies, and development areas, content and priorities in six major areas: leadership and governance, financing, human resources for health, service delivery, medicine and technology, and health information systems. WHO rehabilitation policies advocates to develop national rehabilitation plans, to establish and improve rehabilitation leaderships and the development of mechanism and capacity of rehabilitation governance, to develop multiple approaches of rehabilitation financing, to integrate rehabilitation into health service system, provides different levels of rehabilitation services in the health service continuum, and to build networks of service delivery, to train professionals, to foster rehabilitation information system within health system, to enhance service quality and service coverage, to focus on key areas and priority programs to meet the diverse needs of different populations, and achieve universal health coverage; to include assistive technology into the rehabilitation service system as a field of medicine and technology; and to collect information on functioning and rehabilitation needs, outcomes and impacts of rehabilitation services in the health information system, and conduct evidence-based researches on rehabilitation systems. Conclusion:The framework and contents of WHO's international rehabilitation policies have systematically reviewed at the macro, meso, and micro levels with the perspective of WHO six building blocks of the health system. The goal of rehabilitation development is to achieve universal rehabilitation coverage. The conceptual theories of rehabilitation are based on the theories of people-centered health services and social determinants of health. Rehabilitation is an important initiative to achieve the United Nations 2030 Sustainable Development Goals. The international rehabilitation health policy system is built on six major areas of rehabilitation: leadership and governance, rehabilitation financing, rehabilitation human resources, rehabilitation service delivery, rehabilitation-related medicine and technology, and rehabilitation and health information system. The policy and action strategies for rehabilitation development, as well as specific implementation paths and methods, at macro, meso and micro levels: theory and policy, policy action, and implementation methods and tools have been reviewed and discussed. The implementation of the WHO rehabilitation policies advocates to take the following actions: strengthening the leadership, governance, planning and coordination capacity of rehabilitation services; constructing a reasonable rehabilitation financing mechanism and raising necessary funds for rehabilitation; improving the training and guarantee mechanism of rehabilitation human resources; enhancing the professional capacity of rehabilitation personnel, improving the capacity of rehabilitation service delivery and improving service quality; improving the quality and accessibility of assistive products and assistive technology services; establishing health information system covering functioning, disability and rehabilitation, and conducting scientific researches on rehabilitation.

The historical evolution， fermentation technology and key links of Sojae Semen Praeparatum （SSP） were sorted out by consulting ancient books and modern literature， and the influencing factors and control methods of quality were analyzed and summarized in order to provide reference for the quality control of SSP. After analysis， it was found that in the fermentation process of SSP， fermentation strains， miscellaneous bacteria， temperature and humidity were all important factors affecting the quality of SSP. The condition control of "post fermentation" process has been paid more attention to in the past dynasties. In addition， the delicious SSP recognized in ancient times should be made from mold fermentation， and the breeding and application of fermented mold may be the key point to solve the quality problem of SSP. Therefore， based on the evaluation indexes of SSP in the past dynasties， it is of great significance to study and optimize the technological conditions such as strain， temperature and humidity in depth to improve the quality of SSP.

Objective:To evaluate the safety, efficacy and long-term survival of endoscopic submucosal dissection (ESD) for colorectal precancerous lesions and early cancer in the elderly over 80 years old.Methods:Clinical data of colorectal precancerous lesions and early cancer treated with ESD from January 2007 to December 2014 at Endoscopy Center of Zhongshan Hospital, Fudan University were retrospectively analyzed. A total of 721 patients with 778 lesions were included in this study. These patients were stratified by age: the super-elderly group (≥80 years old, 55 patients, 7.6%) and the non-super-elderly group (<80 years old, 666 patients, 92.4%). The outcomes of ESD, complication incidences, pathological characteristics, and long-term survival were compared between the two groups.Results:Except that the incidence of chronic concomitant diseases in the super-elderly group was significantly higher than that in the non-super-elderly group [54.5% (30/55) VS 31.5% (210/666), P<0.001], other baseline characteristics were not significantly different ( P>0.05). There were no significant differences in the complete resection rate [93.1%(54/58) VS 95.3%(686/720)], the R0 resection rate [89.7% (52/58) VS 93.2% (671/720)], the curative resection rate [84.5% (49/58) VS 90.3% (650/720)], the complication incidence [5.5% (3/55) VS 2.7%(18/666)], or the median hospitalization (2.98 days VS 2.54 days) between the two groups (all P>0.05). The three-year overall survival rates of the super-elderly group and non-super-elderly group were 95.8% and 98.0%, respectively, and the five-year overall survival rates were 85.1% and 97.4%, respectively. Conclusion:Colorectal ESD is safe and effective for elderly patients (age ≥80 years old) despite a significantly higher incidence of chronic concomitant diseases than that in the non-super-elderly patients.

Objective:To explore systematic implementation of World Health Organization Family International Classifications (WHO-FICs) in the field of rehabilitation: the theoretical and policy framework at macro level, governance and management mechanism at meso level, and implementation modules at micro levels, respectively. Methods:The policy and theoretical framework of rehabilitation development was discussed based on the international rehabilitation policy documents of WHO, mainly as World Report on Disability, Global Action Plan on Disability and Rehabilitation in Health Service System. Protocol and roadmap of systematic implementation of WHO-FICs, including International Classification of Diseases (ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Intervention (ICHIβ-2) was proposed. Results:With the use of WHO-FICs, the theoretical and policy framework of rehabilitation was constructed, and the contents and principles of modern rehabilitation services were clarified at macro-level. Rehabilitation is an important part of health service, there are six building blocks: i.e. leadership and governance, financing, human resources for health, service providing, medical technology and health information system. It proposed to use knowledge management system of WHO-FICs, including the classification, nomenclature, definitions, descriptions, terminology and coding systems, to standardize rehabilitation evaluation and statistics. The management and governance system of rehabilitation should be implemented using WHO-FICs. Rehabilitation services are based on the bio-psycho-social model and implemented the principles of people-centered and functioning-oriented. The systematic implementation of WHO-FICs in rehabilitation abide by the model of "Evaluation (ICHI)－Evaluation, Description, Classification and Coding of Functioning (ICF)－Disease Classification, Diagnosis and Coding (ICD)－Rehabilitation Intervention (ICHI)", and with the standardized process of "Evaluation (Functioning and unmet needs)－Diagnose (Disease and Functioning)－Planning of Rehabilitation－Intervention－Evaluation of Outcome". The mic-modules of implementation of WHO-FICs in rehabilitation had been constructed. There were 28 categories of diseases, 7 categories of functioning and 6 categories of rehabilitation interventions in rehabilitation proposed by International Society of Physical and Rehabilitation Medicine. According to ICD-11 and ICF, it proposed to use WHO Disability Assessment Schedule 2.0 (WHODAS 2.0), Brief Model Disability Survey (MDS-B) and VB40 Generic Functioning Domains (VB40), and the ICF core-sets in evaluation of functioning and rehabilitation outcome. The implementation of WHO-FICs in management of medical records and reporting realized the standardized management of medical record, encoding of diseases, functioning and intervention, reporting of performance, and provided tools for billing, reimbursement and payment management of rehabilitation. It proposed to develop WHO-FICs based clinical data sets and big data to implement functioning-related Diagnosis Related Groups and case-mix statistics. Conclusion:With the systematic implementation of WHO-FICs in rehabilitation, the policy and theoretical framework at macro level had been developed. The mechanism of management and governance at meso level had been explored. The application modules and approaches at micro level had been established. A scientific and effective overall solution had been proposed to enhance the scientific, standardized, refined and informatization level, strengthen the level and governance capacity, and improve the quality, safety and the coverage of rehabilitation services.

Objective: To evaluate the safety and efficacy of dental floss traction-assisted endoscopic submucosal dissection (DFS-ESD) for rectal neuroendocrine neoplasm (NEN). Methods: A retrospective cohort study was performed. Clinical data of rectal NEN patients undergoing ESD at Endoscopy Center of Zhongshan Hospital, Fudan University from January 2016 to December 2017 were retrospectively analyzed. Inclusion criteria: 1) age of 18 to 80 years old; 2) maximal diameter of lesions <1.5 cm; 3) tumor locating in the submucosa without invasion into the muscularis propria; 4) no enlarged lymph nodes around bowel and in abdominal cavity; 5) ESD requested actively by patients. A total of 37 patients were enrolled, including 23 male and 14 female cases with mean age of (56.0±11.3) years. All the lesions were single tumor of stage T1, and the mean size was 0.8±0.2(0.5-1.2) cm. Postoperative pathology revealed all samples as neuroendocrine tumors (NET). Seventeen patients received DFS-ESD treatment (DFS-ESD group) and 20 patient received conventional ESD treatment (conventional ESD group). In DFS-ESD group, after the mucosa was partly incised along the marker dots, the endoscopy was extracted, and the dental floss was tied to one arm of the metallic clip. When the endoscope was reinserted, the hemoclip was attached onto the incised mucosa; another hemoclip was attached onto normal mucosa opposite to the lesion in the same way. The submucosa was clearly exposed with the traction of dental floss and the resection could proceed. The conventional ESD group received the traditional ESD operation procedure. The operation time, modified operation time (remaining time after excluding the assembly time of dental floss traction in DFS-ESD group), en bloc resection rate, R0 resection rate, morbidity of operative complication, recurrence and metastasis were compared between two groups. Results: The average tumor size was (0.8±0.2) cm in DFS-ESD group and (0.7±0.2) cm in conventional ESD group (t=0.425, P=0.673). According to postoperative pathological grading of rectal neuroendocrine neoplasm, 13 were G1 and 4 were G2 in DFS-ESD group, while 17 cases were G1 and 3 cases were G2 in conventional ESD group without significant difference (P=0.680). There were no significant differences in baseline data between in the two groups (all P>0.05). All the basal resection margins were negative, the en bloc resection rate was 100% and the R0 resection rate was 100%. Pathological results showed tumor tissue close to the burning margin in 5 cases of conventional ESD group and in 2 cases of DFS-ESD group (P=0.416). The operation time was (17.9±6.6) minutes in conventional ESD group and (14.7±3.3) minutes in DFS-ESD group (t=1.776, P=0.084). The modified operation time of DFS-ESD group was (11.9±2.8) minutes, which was significantly shorter than (17.9±6.6) minutes in conventional ESD group (t=3.425, P=0.002). The hospital stay was (2.3±0.6) days and (2.0±0.5) days in conventional ESD group and DFS-ESD group, respectively, without significant difference (t=1.436, P=0.160). No patient was transferred to surgery, and no delayed bleeding or perforation occurred in either group. There was no recurrence or primary tumor-related death, and all the patients recovered well during a follow-up period of 14(1-24) months. Conclusion Dental floss traction-assisted ESD for rectal neuroendocrine neoplasm can simplify operation and ensure negative basal margin.

Objective To explore the feasibility, safety and effectiveness of endoscopic submucosal dissection ( ESD) in the treatment of the synchronous multiple early cancer or precancerous lesions in esophageal and stomach. Methods A retrospective study was conducted on the data of 5 patients with synchronous multiple early cancer or precancerous lesions in esophageal and stomach who were treated by ESD in Endoscopy Center of Zhongshan Hospital from January 2008 to December 2013. The characteristics of lesions, and results of therapy and follow-up were analyzed. Results All 5 patients were male with mean age of 67. 8±13. 1 years. The mean size of esophageal lesions was 2. 1±0. 9 cm with 1 lesion located in the upper esophagus and 4 in the middle. The mean size of gastric lesions was 2. 5±1. 5 cm with 2 lesions in the antrum, 2 in the gastric angle and 1 in cardia. Lesions in 4 cases were removed at the same time and 1 at different times. All lesions achieved complete resection. Postoperative pathological results showed that there were 2 cases of esophageal precancerous lesions with gastric precancerous lesions, 2 cases of esophageal precancerous lesions with early gastric cancer, and 1 case of early esophageal cancer with early gastric cancer. The 5 patients with 10 lesions all achieved curative resection. Postoperative esophageal stricture occurred in 1 case, which was improved after dilation. Median follow-up time was 72 months, when 3 patients survived and 2 patients died. However, the cause of death was not associated with the treatment. Conclusion ESD is a minimally invasive endoscopic method for treating synchronous multiple primary early cancers in esophagus and stomach.
