Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease affecting both upper and lower motor neurons. ALS patients develop progressive muscle atrophy, muscle weak and paralysis, finally died of respiratory failure. ALS is characterized by fast aggression and high mortality. What' s more, the disease is highly heterogeneous with unclear pathogenesis and lacks effective drugs for therapy. In this review, we summarize the main pathological mechanisms and the current drugs under development for ALS, which may provide a reference for the drug discovery in the future.

Objective To evaluate the application effect of broth microdilution(BMD)method in susceptibility testing of multidrug-resistant Mycobacterium tuberculosis(MDR-MTB).Methods The Roche's proportion method and BMD method were adopted in drug susceptibility testing on 108 MDR-MTB strains and 11 non-MDR-MTB strains in Hainan Province.Whole genome sequencing(WGS)was performed on strains with inconsistent results by the above two methods.Results The average time to acquire drug susceptibility testing results by Roche's propor-tional method and BMD method were 28.0 and 8.5 days,respectively.Roche's proportional method showed higher resistance rates to isoniazid(INH),rifampicin(RFP),ethambutol(EMB),kanamycin(KM),and capreomycin(CPM)than BMD method(all P＜0.001).BMD method showed higher resistance rates to protionamide(PTO)and para-aminosalicylic acid(PAS)than Roche's proportional method(both P＜0.001).Taking Roche's proportional method as the gold standard,the sensitivity and specificity of BMD method for testing drug resistance were 50.00％-100％and 95.69％-100％,respectively.Except EMB(87.39％)and INH(94.96％),the consistency rates of the BMD method in testing drug resistance of other drugs were all ≥95.00％.The overall consistency rate between Roche's proportional method and WGS was 76.19％(32/42),while the consistency rate between BMD method and WGS was 23.81％(10/42),difference was statistically significant(x2=23.048,P＜0.001).34 MTB strains showed inconsistent results by two drug susceptibility testing methods.Among the 26 MTB strains that were resis-tant in Roche's proportion method but sensitive in BMD method,22 strains(84.62％)had mutations in relevant re-sistance genes.Among the 11 MTB strains that were sensitive in Roche's proportion method but resistant in BMD method,5 strains(45.45％)had mutations in relevant resistance genes.Conclusion BMD method is an accurate and rapid MDR-MTB susceptibility testing method,but further improvement and optimization are still needed.Drug resistance is closely related to mutations in relevant resistance genes.

OBJECTIVE To evaluate the effectiveness， safety， economy， innovation， suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein （EC）， and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin （TB-PPD） were analyzed by the method of systematic review. Cost minimization analysis， cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD， and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation， suitability and accessibility were determined by systematic review and improved Delphi expert consultation， and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness， safety， economy， innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent， while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight， the scores of effectiveness， safety， economy， innovation， suitability， accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD， EC performs better in all dimensions of effectiveness， safety， economy， innovation， suitability and accessibility. However， it is worth noting that EC should further improve its availability in the dimension of accessibility.

Objective: To analyze the direct economic burden caused by measles cases in Shanghai from 2017 to 2019 and its influencing factors. Methods: A total of 161 laboratory-confirmed measles cases reported from January 1, 2017, to December 31, 2019, in Shanghai were included in the study through the "Measles Surveillance Information Reporting and Management System" of the "China Disease Surveillance Information Reporting and Management System". Through telephone follow-up and consulting hospital data, the basic information of population, medical treatment situation, medical treatment costs and other information were collected, and the direct economic burden of cases was calculated, including registration fees, examination fees, hospitalization fees, medical fees and other disease treatment expenses, as well as transportation and other expenses of cases. The multiple linear regression model was used to analyze the main influencing factors of the direct economic burden. Results: The age of 161 measles cases M (Q₁, Q₃) was 28.21 (13.33, 37.00) years. Male cases (56.52%) were more than female cases (43.48%). The largest number of cases was≥18 years old (70.81%). The total direct economic burden of 161 measles cases was 540 851.14 yuan, and the per capita direct economic burden was 3 359.32 yuan. The direct economic burden M (Q₁, Q₃) was 873.00 (245.01, 4 014.79) yuan per person. The results of multiple linear regression model analysis showed that compared with other and unknown occupations, central areas and non-hospitalized cases, the direct economic burden of measles cases was higher in scattered children, childcare children, students, and cadre staff in the occupational distribution, suburban areas and hospitalized, with the coefficient of β (95%CI) values of 0.388 (0.150-0.627), 0.297 (0.025-0.569), 0.327 (0.148-0.506) and 1.031 (0.853-1.209), respectively (all P values<0.05). Conclusion: The direct economic burden of some measles cases in Shanghai is relatively high. Occupation, area of residence and hospitalization are the main factors influencing the direct economic burden of measles cases.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Objective: To systematically introduce the design of case-cohort study and the statistical methods of relative risk estimation and their application in the design. Methods: First, we introduced the basic principles of case-cohort study design. Secondly, Prentice's method, Self-Prentice method and Barlow method were described in the weighted Cox proportional hazard regression models in detail, finally, the data from the Shanghai Women's Health Study were used as an example to analyze the association between obesity and liver cancer incidence in the full cohort and case-cohort sample, and the results of parameters from each method were compared. Results: Significant association was observed between obesity and risk for liver cancer incidence in women in both the full cohort and the case-cohort sample. In the Cox proportional hazard regression model, the partial regression coefficients of the full cohort and the case-cohort sample fluctuated with the adjustment of confounding factors, but the hazard ratio estimates of them were close. There was a difference in the standard error of the partial regression coefficient between the full cohort and the case-cohort sample. The standard error of the partial regression coefficient of the case-cohort sample was larger than that of the full cohort, resulting in a wider 95% confidence interval of the relative risk. In the weighted Cox proportional hazard regression model, the standard error of the partial regression coefficient of Prentice's method was closer to the parameter estimates from full cohort than Self-Prentice method and Barlow method, and the 95% confidence interval of hazard ratio was closer to that of the full cohort. Conclusions: Case-cohort design could yield parameter results closer to the full cohort by collecting and analyzing data from sub-cohort members and patients with the disease, and reduce sample size and improve research efficiency. The results suggested that Prentice's method would be preferred in case-cohort design.

Objective: To explore the medication compliance for secondary prevention drugs and long-term prognosis of patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) between hospitals in different regions of China. Methods: The Optimal Antiplatelet Therapy for Chinese Patients with Coronary Artery Disease (OPT-CAD) study was a prospective, multi-center and registered study. Patients diagnosed as ACS and underwent PCI in OPT-CAD study were selected. Taking the Yangtze River as the dividing line between the south and the north of China, these patients were divided into two groups according to the hospitals where the patients visited, namely the southerns region group (n=1 958) and the northerns region group (n=5 091). In order to reduce selection bias and potential confounding factors, the patients in the two groups were matched by the tendency score, and the patients in the two groups were matched by the 1: 1 nearest match method according to the tendency score. The main endpoint of this study was the major adverse cardiovascular and cerebrovascular events (MACCE) occurring within 5 years after discharge, namely the composite endpoint of cardiac death, myocardial infarction, and/or ischemic stroke. Secondary endpoints were all-cause death, cardiac death, myocardial infarction, ischemic stroke, and type 2, 3, and 5 bleeding events defined by the Academic Research Consortium on Hemorrhage (BARC) within 5 years. The secondary preventive drugs was recorded, including antiplatelet drugs, statins, beta blockers, angiotensin converting enzyme inhibitors/angiotensinⅡreceptor blockers (ACEI/ARB), etc. Before and after the matching, the secondary preventive medication and the incidence of clinical events of the two groups were compared. Results: A total of 7 049 ACS patients, including 1 958 patients in the southern region group and 5 091 patients in the northern region group were enrolled in this study. There were 5 319 males (37.9%), and the aged was (60.7±6.7) years. After propensity score matching, there were 1 324 cases in each group. Before matching, in the northern region group, the proportion of smoking, hypertension and diabetes, previous history (myocardial infarction, PCI and stroke) and family history of coronary heart disease were higher (all P<0.05). The proportion of complex lesions, diffuse lesions, small vessel lesions and thrombotic lesions in the northern region group was higher than that in the southern region group (all P<0.05). Sixty months after discharge, the antiplatelet patterns were quite different between patients in the northern and southern region group (P<0.001). The proportion of clopidogrel monotherapy in the southern region group was higher than that in the northern region group (9.8% (130/1324) vs. 1.1% (14/1324)), while the proportion of aspirin monotherapy in the northern region group was higher than that in the southern region group (67.4% (893/1324) vs. 46.5% (616/1324)). As for the use of other secondary prophylactic drugs, the proportion of patients in southern region group receiving beta blockers (24.5% (325/1324) vs. 16.8% (222/1324), P<0.001) and ACEI/ARB (19.4% (257/1324) vs. 10.0% (133/1324), P<0.001) was higher than that in northern region group. After matching, the incidence of MACCE (8.4%(111/1 324) vs.6.2% (82/1 324), P=0.030) and BARC 2, 3 and 5 bleeding (6.0% (80/1 324) vs. 4.0% (53/1 324), P=0.020) was higher in patients in northern region group. Conclusions: ACS patients who undergo PCI in northern area hospital is at higher prevalence of comorbidities and complicated coronary artery lesions compared to patients in the southern area hospital, and the drug compliance is worse than that in southern area, and the prognosis is also relatively poor.

Objective To systematically analyze the framework and core content of physical activity inclusive school health policies. Methods This study conducted systematic content analysis of key messages of WHO key documents related to physical activity and school health services, and constructed policy and research framework. WHO's key policy documents in the field of school health included: Making Every School a Health-Promoting School Implementation Guidelines, WHO Guidelines on School Health Services, and the Global Criteria and Indicators for Making Every School a Health-Promoting School, and the key documents in the field of physical activity mainly include Global Action Plan for Physical Activity Promotion 2018-2030: Strengthening Physical Activity for a Healthy World, and WHO Guidelines on Physical Activity and Sedentary Behavior (Children and adolescents). Results Physical activity, as a health strategy and development strategy, is one of the most important tools for achieving health-promoting schools. In the area of health and education, the key to building health-promoting schools is to focus on child functioning and development, with the goal of promoting healthy inclusion and equity in schools. In the school setting, physical activity for children and adolescents is integrated into the school health service continuum with a focus on health promotion. At the macro level, the state and relevant authorities should establish a strategic structure and strategic planning for the integration of physical activity into the school health service system. At the meso level, educational institutions should develop and improve school health service policies and programs, and improve school health service tools based on the requirements of WHO school health service guidelines. Child health services are achieved through the provision of high-quality physical education programs and after-school physical activities. At the micro level, guided by global standards for building health-promoting schools, physical activity is promoted in the form of lessons and activities for healthy child development. Integrating physical activity into the school health service system can be done in six areas: school health leadership and governance, school infrastructure funding, school health service delivery that supports physical activity, human resources for school health, school health-related medicine and technology, and school health information system. We need to implement health-promoting school policies, strengthen multi-level school leadership and governance, raise the necessary funds to develop human resources adapted to the construction of health-promoting schools and build programs to support physical activity. Conclusion School health service is an important area for promoting children's health and achieving the UN 2030 Sustainable Development Goals, and physical activity is an important strategy of school health services. Policy documents issued by WHO construct the integration of physical activity into the policy framework of the school health service system, of which the core component is to integrate physical activity into the health-promoting school with educational and physical activity approaches. According to the WHO six building blocks of health service system, the integration of physical activity into the school health requires strengthening school health leadership and governance, improving school infrastructure financing, developing school health human resources, developing school-based health-related medical technologies, and establishing a health information system for sharing student health data.

Objective To explore the theories, content and approaches of integrating physical activity in children's eye health service system in the context of health services. Methods From the perspectives of six building blocks of WHO health system, namely, leadership and governance, financing, human resources for health, service delivery, medical technology, and health information system, we analyzed the policy framework and key contents related to school-based eye health and physical activity, and explored how to promote the implementation of physical activity into the school-based eye health service system, and the integration of physical activity into the eye health continuum: prevention, intervention, rehabilitation, and health promotion. Results In perspective of health system, the integration of physical activity into school-based eye health services should be in accordance with the five principles of cross-cutting health services, namely, universal accessibility and equity, human rights, evidence-based, life-span, and empowerment. According to the World Vision Report, WHO advocates to build a person-centered eye health service system, and person-centeredness is the core concept of the new model of school-based eye health services and physical activity integration. WHO advocates a school-based approach to education and physical activity in health-promoting schools to promote student health, physical activity as a preventive, interventional, rehabilitation and health promotive measure related to children's eye health, and vigorously train professionals within schools who have knowledge and skills related to physical activity and eye health, build an information system on physical activity and children's eye health, and promote the integration of physical activity into the school-based eye health service system. Conclusion Physical activity is an important measure to promote children's eye health and an important component to achieve a person-centered eye health service system. Based on the six building blocks of the WHO health service system, a school-based eye health service that integrates a theoretical and methodological system of physical activity is constructed, requiring the provision of health promotion methods such as education and physical activity in the school setting, to enhance leadership and governance of eye health services based on educational and physical activity approaches in the school setting, establish new funding mechanisms, provide financial security, develop human resources related to physical activity for eye health, improve related service delivery systems, develop high-quality physical activity intervention eye health techniques and equipment, and integrate information on children's physical activity and eye health into school health information systems to achieve children's eye health and promote their physical and mental development.
