Meta-analysis of the efficacy of invisible orthodontic appliances for maxillary molar distalization in adult patients / 口腔疾病防治

Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.

Objective@#To evaluate the performance of four simplified screening methods of elevated blood pressure commonly used among children and adolescents according to Chinese guidelines for prevention and treatment of hypertension (revised in 2018), so as to provide a reference for the early detection of the elevated blood pressure among children and adolescents.@*Methods@#Stratified cluster random sampling method was used to monitor the physical fitness of 5 211 children and adolescents in a city of Shanxi Province from October to November 2021. Chinese guidelines for prevention and treatment of hypertension was considered as gold standard, and sensitivity, specificity, area under the curve (AUC) and Kappa value were calculated to evaluate the screening effectiveness of formula method, height specific method, age group specific method, sex and age specific method for screening elevated blood pressure.@*Results@#The detection rates of elevated blood pressure among children and adolescents screened by gold standard, formula method, height specific method,age group specific method, sex and age specific method were 21.9%, 24.0%, 21.1%, 24.5% and 20.2%, respectively. There was no significant difference between prevalence of elevated blood pressure screened by formula method, sex and age specific method and gold standard( χ 2=1.21, 1.41, P >0.05), whereas height specific method and age group specific method had significant differences with gold standard ( χ 2=20.39, 67.09, P <0.05). AUC was the largest for height specific method [0.94(95% CI =0.93-0.95)], and the smallest for age group specific method [0.87(95% CI = 0.86 -0.88)]. The Kappa values of height specific method (0.89) and sex and age specific method (0.89) were both greater than 0.85 , which were more consistent with the screening effectiveness of gold standard. When comparing by sex, age and body mass index (BMI), the screening effectivenesses were consistent with the overall in boys, 6-11 years and normal body weight groups, while the screening effectivenesses were different in girls, 12-17 years, overweight and obese groups. The AUC (0.87), Kappa value (0.71) and sensitivity (82.33%) of age group specific method were the lowest and the screening effectiveness was the worst.@*Conclusion@#Height specific method is more effective and can be used for early identification and self detection of blood pressure abnormalities among children and adolescents.

Application of two different methods of visual acuity assessment for myopia screening among lower grade elementary school students / 中国学校卫生

Objective@#To explore two visual acuity standards for examining uncorrected visual acuity (UCVA) to define poor vision in lower grade elementary school students, and to compare the difference of screening myopia rates when combined with non cycloplegic auto refraction (NCAR), so as to provide a scientific basis for standardizing UCVA examination methods using CAR as the gold standard of authenticity and reliability.@*Methods@#From March 22nd to April 9th, 2023, a total of 549 first and second grade students aged 7-8 years from a primary school in Hefei City were selected for the study by convenient cluster sampling method. Two methods were employed for UCVA examination:the first method involved charts where the student could not make mistakes in identifying at least half of the characters per line (V1), and the second method used charts with character sizes ranging from 4.0 -4.5, 4.6-5.0 and 5.1-5.3, without allowing 1, 2 and 3 errors per line (V2). While NCAR was performed, then 187 students underwent CAR examination. Paired Wilcoxon rank-sum test and McNemar test were used to compare the differences between V1 and V2 methods in defining poor vision and screening myopia rates. Using CAR as the gold standard, the authenticity and reliability of defining screening myopia rates through the combination of V1 and V2 methods along with NCAR were evaluated.@*Results@#The UCVA examination results for V1 and V2 showed statistically significant differences in both the right eye [5.0(4.9,5.0), 4.9(4.8,5.0)] and the left eye [ 5.0 (4.9,5.0), 4.9(4.8,5.0)] ( Z=-13.95, -13.34, P <0.01). The detection rates of poor vision for the right eye were 43.53% for V1 and 63.21% for V2, and the left eye with 44.08% for V1 and 62.11% for V2, with statistically significant differences ( χ 2= 106.01 , 95.09, P <0.01). When screening myopia rates were assessed for UCNA methods combined with NCAR, the right eye rates were 21.49% for V1 and 24.59% for V2, and the left eye rates were 21.31% for V1 and 23.13% for V2, with statistically significant differences ( χ 2=15.06, 8.10, P <0.01). Using CAR as the gold standard, the detection rates in the right eye and left eye were 16.58 % and 17.11%, respectively. The Youden indices for defining screening myopia in the right eye were 0.80 for V1 and 0.79 for V2, and the left eye with 0.85 for V1 and 0.83 for V2. The agreement rates for the right eye were 91.98 % for V1 and 89.30% for V2, and the left eye with 94.12% for V1 and 91.98% for V2. The Kappa values for the right eye were 0.73 for V1 and 0.67 for V2, and the left eye with 0.81 for V1 and 0.75 for V2.@*Conclusions@#Authenticity and reliability of two UCVA examination methods combined with NCAR in defining screening myopia are higher in V1 than V2 methods. It is recommended to unify the visual acuity examination methods by requiring the correct identification of more than half of the total number of visual markers in a row.

Progress of research on evaluation indicators and standards about high-speed train comfort / 中华劳动卫生职业病杂志

The rapid development of high-speed railway in China has proposed higher requests for the comfort level of high-speed trains. However, there is no internationally unified evaluation criterion for high-speed train comfort currently, which therefore substantially affects the comparability and standardization of research results for high-speed train comfort. This paper systematically reviews the research literature about evaluation indicators and standards related to high-speed train comfort, and finds that there is currently no unified definition, evaluation indicators, as well as evaluation criterion for high-speed train comfort. Most current evaluation criteria are based on a single indicator. Some indicators are simultaneously developed by different apartments and differ between each other, and there is no comprehensive indicator or criteria for high-speed train comfort, restricting the comparison of high-speed train comfort across regions. It is recommended that the administrative department of high-speed railroad in China should organize experts to establish a unified definition of high-speed train comfort, comprehensive evaluation indicators and relevant judgment criteria for high-speed train comfort, in face of the rapid development and globalization of high-speed trains.

Characterization and Comparison Analysis of WHO Monographs on Selected Medicinal Plants and ISO Standards of Chinese Materia Medica / 中国结合医学杂志

Medicinal plants or Chinese materia medica (CMM) are now attracting worldwide attention as they have increasingly prominent advantages over chemical drugs in disease treatment and healthcare. Since the 1990s, World Health Organization (WHO) and International Organization for Standardization established the Technical Committee of Traditional Chinese Medicine (ISO/TC 249) have carried out the development of quality standards on medicinal plants or CMMs respectively, and a considerable number of monographs and international standards have been published. Since the two international organizations adhere to different principles, the standards they develop naturally have different emphasis. Driven by market demand and international trade, ISO mainly takes quality, efficacy and safety into consideration when developing standards, while WHO pays more attention to clinical practice, quality control and medication guidance. Up to now, there is a lack of comparative analysis on the records, background, principles, basic content, and main requirements of quality standards on medicinal plants or CMMs respectively published by WHO and ISO. Therefore, based on international standards of CMM developed by ISO/TC 249 platform and WHO Monographs on Selected Medicinal Plants, this paper systematically compares the purposes, selected principles, standard-developing process, basic content, and main quality requirements to summarize their similarities and differences, and find their merits, aiming to serve as a reference to the development of international standards for CMMs that helps them go global.

Study on the efficacy evaluation criteria of randomized controlled trials of TCM in the treatment for edema / 国际中医中药杂志

Objective:To analyze the efficacy evaluation criteria of the existing TCM treatment for edema RCT research, and to provide reference for the construction of unified standards.Methods:The batabases CNKI, WanFang Data, VIP, CBM, Pubmed and Web of Science were retrieved. The randomized controlled trials for the treatment of edema of TCM research, from September 1, 1993 to July 31, 2022, were screened and included. The content of efficacy evaluation, performed statistics on evaluation standard, the curative effect evaluation indexes, as well as standard composition, usage were extracted. We analyzed the characteristics, application and problems of the existing efficacy evaluation criterion.Results:A total of 123 Chinese articles were included. The included literature involved nephrogenic edema, cardiogenic edema, idiopathic edema, apoplexy limb edema and other edema. In recent years, randomized controlled trials on the treatment of edema by TCM have mainly used four efficacy evaluation criteria. Of which the Guidelines for Clinical Research on New Chinese Medicines (Trial) in 2002 had the highest utilization rate of 29.27%. Secondly, the utilization rate of Standard for Diagnosis and Curative Effect of TCM Diseases and Syndromes was 21.14%. The rest of the criteria were used by less than 6%. While 39.02% of the literature did not use the standards or used self-designed standards. Among the composition of efficacy evaluation indices, the application rate of TCM syndrome or symptom efficacy index was the highest (91.87%), the utilization rate of the Minnesota Living with Heart Failure Questionnaire Indicators was only 4.88%; biochemical tests accounted for a large proportion of Western medical indicators, while the measurement of edema severity was rarely applied. Conclusions:At present, the evaluation criteria of edema curative effect are diversified and insufficiently popularized, which need to be further screened and improved. It is suggested to construct a TCM edema efficacy evaluation model based on the characteristics of edema syndrome, comprehensively evaluate the efficacy from multiple dimensions such as TCM syndromes, western medicine indicators, and quality of life, and improve the scientific indicators.

Reflections on nomenclature and expansion of surgical indications for endoscopic spinal surgery / 国际外科学杂志

In recent years, with the development and maturity of endoscopic technique, endoscopic spinal surgery represented by water media and optical rigid endoscope has been widely used in the treatment of many disorders in the cervical, thoracic and lumbar spine. Endoscopic spinal surgery shows similar clinical effects as traditional open surgery or other minimally invasive procedures, and is favored by spinal surgeons due to its advantages of less trauma and rapid recovery after surgery. However, the large-scale application of endoscopic technique brings problems such as non-standard nomenclature and unreasonable indications. Therefore, this article will summarize the surgical nomenclature and indications of endoscopic spinal surgery, in order to provide a reference for spinal surgeons to understand and apply endoscopic technology reasonably.

Application strategy of the Principles and Guidelines for Human Factors/Ergonomics (HFE) Design and Management of Work Systems in China / 中国职业医学

To provide in-depth information and guidance on ergonomics, the International Labour Organization (ILO) had issued a series of conventions, recommendations, and resolutions on human factors/ergonomics (HFE) and had published HFE guides and toolkits. In 2021, the ILO and the International Ergonomics Association released an international guideline on HFE entitled Principles and Guidelines for Human Factors/Ergonomics (HFE) Design and Management of Work Systems (hereinafter referred to as the HEF Guidelines), aiming to improve the occupational safety, health, and the well-being of workers from the perspective of work system sustainability. There are currently 112 national health standards in China related to HFE, of which 79 (accounting for 71%) are equivalent to relevant standards from the International Organization for Standardization. Most of the recommended standards do not meet the applicability requirements of HFE for the Chinese workforce, as they are different from the national occupational health standard system. At present, China's HFE capability cannot meet the needs of the workforce, and there is still a gap between occupational diseases related to HFE included in the Occupational Disease List of China and those compared to the ILO. In the future, China needs to pay attention to the application of the HEF Guidelines, further improve the technical services for occupational health, include diseases caused by poor ergonomics in the national occupational disease list, strengthen the HFE standard system in the national occupational health standard system, actively promote the application of action-oriented HFE tools, enhance “human-machine coordination” and “person-job matching”, and focus on physical and cognitive HFE design to promote equality in workplace and reduce the occurrence of occupational and work-related diseases.
