ObjectiveTo assess the efficacy of lymphadenectomy in different regions for esophageal squamous cell carcinomas located differently according to the lymph node grouping by Chinese expert consensus. MethodsThe medical records of 1 061 patients (886 males and 175 females with a median age of 60 (54, 65) years with esophageal cancer from March 2011 to December 2017 in our hospital were retrospectively analyzed. According to the pathological report, the lymph nodes were regrouped according to the Chinese lymph nodes grouping standard of esophageal cancer. The metastasis rate of each group of lymph nodes, the 5-year survival rate of metastatic patients and efficacy index (EI) were calculated. ResultsThe upper thoracic esophageal cancer mainly metastasized to the lymph nodes of C201-203 groups. The middle and lower thoracic tumors mainly metastasized to the lymph nodes of C205-207 groups. The lower thoracic tumor had a higher rate of metastasis to the abdominal lymph nodes. According to the metastasis rate, the mediastinal lymph nodes were divided into three regions: an upper mediastinum (C201-204), a middle mediastinum (C205-206), and a lower mediastinum (C207-209). The EIs of lymph nodes of C201-203 and C205-207 groups were higher. For patients with C201-207 groups metastasis, the 5-year survival rates ranged from 13.39% to 21.60%. For patients with positive lymph nodes in each region, tumors at different primary locations had no statistical difference in long-term survival (P>0.05). Patients with lymph nodes of C205 group in the upper thoracic tumors had lower EI and those in the middle and lower thoracic tumors had higher EIs. ConclusionThe effect of lymph node dissection in each area varies with the location of the tumor. No matter where the tumor is, it is necessary to dissect the upper mediastinal lymph nodes, especially the lymph nodes adjacent to the left and right recurrent laryngeal nerves. Group C205 should be classified into the lower mediastinal lymph nodes.
Objective To explore the research trends of traditional Chinese exercise in the rehabilitation of chronic obstructive pulmonary disease (COPD). Methods The Web of Science core collection database was searched to collect literature on traditional Chinese exercise for COPD rehabilitation published from 2004 to 2023. VOSviewer was used for bibliometric analysis of publication year, author, publication institution and country, citation and co-citation information. Results A total of 125 publications were included. No relevant publication was published from 2004 to 2008. Since 2009, the overall number of publications had shown a fluctuating upward trend, with no publications in 2012. From 2019 to 2023, the number of publications on related topics remained at a high level. Reached maximum publication volume in 2020. The annual citation frequency also showed a fluctuating increase, reaching its peak in 2022. Based on comprehensive analysis, Peter M. Wayne and Wu Weibing were the authors with high productivity, high citation, and frequent collaborations. The country with the highest number of publications was China, and the highest institution was Shanghai University of Sport. Initially, the keywords focused on rehabilitation, exercise testing, aerobic exercise, resistance exercise, and respiratory muscle strength. As the times progressed, the focus shifted to lung function, exercise tolerance, and mental health. The current trends included self-management and telemedicine. Conclusions Traditional Chinese exercises have been widely applied in the clinical practice of COPD rehabilitation, showing an upward trend. Facilitating patient self-management and establishing the role and significance of traditional Chinese exercises in remote healthcare for COPD patients may be the focus of future research.
Objective To investigate the relationship between estimated glucose disposal rate (eGDR) and the incidence of cardiovascular disease (CVD) in individuals without diabetes and those with diabetes. Methods Participants were drawn from the China Health and Retirement Longitudinal Study from 2011 to 2018. Participants were divided into four subgroups based on quartiles of baseline eGDR. In this study, data were analyzed using Kaplan-Meier survival curves, Cox proportional hazards models, restricted cubic spline curves, subgroup analyses, and receiver operator characteristic curves. Results A total of 6 283 participants were included. Among them, 47.2% are male, with an average age of (59.6±9.5) years; 285 cases (4.5%) had diabetes; there were 1 571 cases in Q1 group, 1 572 cases in Q2 group, 1 583 cases in Q3 group, and 1 557 cases in Q4 group. A total of 761 CVD events occurred. According to the multivariate-adjusted model, baseline eGDR levels were significantly associated with the risk of CVD events (P<0.05). Baseline eGDR was associated with the risk of CVD events in individuals without diabetes (P<0.05), but the results were not entirely consistent for those with diabetes [CVD: hazard ratio (HR)=0.85, 95% confidence interval (CI) (0.75, 0.96), P=0.012; heart disease: HR=0.91, 95%CI (0.78, 1.06), P=0.211; stroke: HR=0.74, 95%CI (0.58, 0.93), P=0.012]. Restricted cubic spline curves revealed significant negative linear relationships between baseline eGDR and CVD, heart disease, and stroke. Subgroup analyses with interaction testing revealed that the association between baseline eGDR and CVD was not modified by age, sex, smoking status, alcohol consumption, or dyslipidemia. Receiver operator characteristic curves further demonstrated that baseline eGDR exhibited significantly better predictive performance than the triglyceride-glucose (TyG) index, obesity indices, and the TyG index-obesity composite. Conclusions Low level baseline eGDR is associated with an increased risk of CVD in individuals without diabetes. This finding may help improve risk stratification to guide preventive measures and enhance the prognosis of CVD.
ObjectiveTo systematically investigate the current status of reporting health economics evidence in clinical practice guidelines and expert consensuses published in China from 2021 to 2023, providing references for the formulation and revision of guidelines and consensuses in our country. MethodsComputer searches were conducted in the CNKI, CBM, WanFang Data, China Academic Journals Full-text Database, PubMed, and Web of Science to collect clinical practice guidelines and expert consensuses published in China from 2021 to 2023. Two researchers independently screened the literature, extracted information on the inclusion of economic evidence in guidelines and consensuses, and then used quantitative analysis methods for description. ResultsA total of 4 236 relevant articles were included, of which 1 066 (25.17%) reported health economics evidence; 120 (11.26%) reported health economics evidence in the formation of recommendation opinions; 109 (10.23%) reported health economics evidence in the grading of evidence quality; 832 (78.05%) reported health economics evidence in the interpretation and explanation of recommendation opinions. ConclusionThe reporting rate of health economics evidence in clinical practice guidelines and expert consensuses published in China is not high. The reporting rate of health economics evidence in consensuses is lower than that in guidelines. It is recommended that during the formulation process of guidelines and consensuses, the application of health economics evidence should be further strengthened in aspects such as the formation of recommendation opinions, the grading of evidence quality, and the interpretation and explanation of recommendation opinions, in order to improve the scientific, rigorous, and applicability of clinical practice guidelines and expert consensuses, and to play the role of guidelines and consensuses in optimizing the allocation of health resources, improving clinical diagnosis and treatment effects, and enhancing the quality of medical care.
ObjectivesTo investigate Chinese health practitioners’ usage and demand for clinical practice guidelines in general so as to improve the development and implementation of guidelines.MethodsWe conducted a cross-sectional questionnaire survey that covered health practitioners from different levels of medical institutions in 17 provinces in China. Attitudes, adherence, usage barriers and demands for clinical practice guidelines were investigated.ResultsA total of 953 health practitioners were involved in the survey in which 931 completed the questionnaires. Respondents generally held positive attitudes toward guidelines and agreed that they improved quality of care and standardized diagnosis and treatment. More than 80% of the respondents reported a fine adherence to guidelines. The most reported barriers to follow the guidelines were " several guidelines are competing” and " lack of facilities and medical resources”. Most respondents agreed that it was necessary to establish a national guideline database, appraise implementation effect of guidelines, develop evaluation tools for guidelines that are applicable for Chinese clinical practice, and provide guidelines training.ConclusionsThis study finds favorable attitudes and fine adherence towards clinical guidelines in general in China. However, internal barriers, such as authority of guidelines, and external barriers, such as supplying system and patients’ preference, can affect guideline dissemination and implementation. It is suggested that establishing a national guidelines database, developing evaluation tools for guidelines that fit for Chinese clinical practice, and provision of guideline training, would facilitate the use of guidelines.
ObjectiveTo systematically review the incidence of internet addiction disorder among college students in China.MethodsPubMed, EMbase, VIP, WanFang Data and CNKI databases were electronically searched to collect cross-sectional studies on incidence rate of college students’ internet addiction in China from inception to February 2020. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by Stata 16.0 software.ResultsA total of 65 cross-sectional studies involving 87 702 subjects were included. The results of meta-analysis showed that: the overall incidence of college students’ internet addiction in China was 10.7% (95%CI 9.6% to 11.8%). The incidence of internet addiction from 2011 to 2018 (11.7%, 95%CI 10.2% to 13.2%) was higher than that from 2005 to 2010 (9.6%, 95%CI 8.1% to 11.1%). The incidence in male students (14.6%, 95%CI 13.1% to 16.0%) was higher than that in female students (6.9%, 95%CI 5.9% to 7.8%). The incidence of urban students (12.2%, 95%CI 9.3% to 15.2%) was higher than that of rural students (9.0%, 95%CI 7.3% to 10.6%). The incidence of students who were not satisfied with their major (16.2%, 95%CI 5.5% to 26.8%) was higher than that of satisfied (5.0%, 95%CI 1.3% to 8.8%). The incidence of students with poor academic performance (29.4%, 95%CI 11.9% to 47%) was higher than of excellent academic performance (4.1%, 95%CI 1.9% to 6.4%).ConclusionsThe incidence rate of internet addiction among college students in China shows an obvious upward trend. There are differences in the incidence rates of internet addiction among college students in different regions. The incidence rates of internet addiction are different among different genders, degree of satisfaction with their majors and academic achievements.
ObjectiveTo provide a basis for timely adjustment of cancer prevention and control measures in China through timely understanding of the latest 2022 global cancer statistics reported in the CA: A Cancer Journal for Clinicians published “Global cancer statistics 2022: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries”. MethodsThe statistical data of GLOBOCAN in 2022 were systematically analyzed and the incidence and mortality of cancer by age, sex, type, and region were comprehensively interpreted. The changing trends in cancer were compared between China and the rest of the world, and the potential risk factors as well as current cancer prevention and control measures were summarized. Results① Globally, for both sexes combined, there were an estimated 19.976 million new cases and 9.744 million cancer deaths in 2022. The age-standardized incidence rate (ASIR) was 196.9 per 100 000 and the age-standardized mortality rate (ASMR) was 91.7 per 100 000 in 2022. The ASIR of all cancers was highest in Europe (268.1 per 100 000) and lowest in South-East Asia (109.6 per 100 000), as well as the ASMR of all cancers was highest in Europe (106.3 per 100 000) and lowest in South-East Asia (71.0 per 100 000). The top three cancer types of newly diagnosed cancer cases were lung, breast, and colorectal cancer, while the top three leading causes of cancer deaths were lung, colorectal, and liver cancer. The incidence and mortality rates of all cancers increased with advancing age. The numbers of newly diagnosed cancer cases and cancer deaths, as well as the age-standardized rates were consistently higher among men compared to women. The lung cancer and breast cancer ranked first in terms of newly diagnosed cancer cases among men and women, respectively. Consistently, the lung cancer and breast cancer were also the leading causes of cancer-related deaths among men and women, respectively. ② In China, there were an estimated 4.825 million new cases and 2.574 million cancer deaths. The ASIR was 201.6 per 100 000 and the ASMR was 96.5 per 100 000 in 2022. The ASIR and ASMR both ranked 65th out of 185 countries. The top three cancer types among newly diagnosed cases were lung cancer, colorectal cancer, and thyroid cancer, while the top three leading causes of cancer deaths were lung cancer, liver cancer, and gastric cancer. ConclusionsThe cancers incidences and deaths worldwide in 2022 have declined from that in 2020 (196.9 per 100 000 versus 201.0 per 100 000, 91.7 per 100 000 versus 100.7 per 100 000, respectively). Lung cancer is the leading type of newly diagnosed cancer both in China and globally. However, the second and third most common cancers in China differ from the global picture. In China, colorectal cancer and thyroid cancer take the second and third spots, respectively; Whereas globally, breast cancer and colorectal cancer occupy these positions. Lung cancer is the first ranked leading cause of death in both China and globally. However, there are differences in the second and third most common causes. In China, liver cancer and gastic cancer take the second and third spots, respectively; While globally, colorectal cancer and liver cancer occupy these positions. This study analyzes the characteristics of the disease burden of cancer in China by comparing the epidemiological features of cancer in China and worldwide, aiming to provide scientific evidences for developing comprehensive cancer prevention and control measures tailored specifically to China’s national conditions.
ObjectiveTo systematically review the prevalence of elder abuse in China.MethodsPubMed, EMbase, Web of Science, CNKI, VIP and WanFang Data databases were electronically searched to collect cross-sectional studies on the prevalence of elder abuse in China from inception to June 2019. Two reviewers independently screened literature, extracted data and assessed risk bias of included studies; then, meta-analysis was performed by R 3.5.1 software.ResultsA total of 11 cross-sectional studies involving 23 020 subjects were included. The results of meta-analysis showed that the prevalence of abuse among the elderly in China was 20.29% (95%CI 12.9% to 28.9%). The highest prevalence of elder abuse subtype was psychological abuse with 15.06% (95%CI 10.2% to 20.6%). The prevalence rates were 20.1% in male and 23.64% in female. The prevalence rates in individuals aged between 60 to 70, 70 to 80 and above 80 were 19.76%, 22.24% and 29.19%, respectively. Illiterates and non-illiterates were 29.39% and 22.52% respectively. Normal marital status was 28.24%, and abnormal status was 31.38%. The elderly living alone was the highest (50.67%), compared with family residents (39.42%) and elderly living in pension institutions (29.94%). The elderly without chronic diseases (16.05%) was lower than elderly with chronic diseases (25.49%), and elderly having normal capability of daily living (26.89%) was lower than elderly having reduced capability of daily living (48.78%). Urban residents were 18.46%, while rural residents were 19.69%.ConclusionsThere is a high incidence of elder abuse in China, and it tends to increase with the increase of age. There are certain differences in the prevalence of elder maltreatment among different genders, ages, educational levels, marital status, living forms and spaces, and health conditions. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion.
Neurofibromatosis type 1 (NF1) is an autosomal dominant neoplastic disease caused by mutations in the NF1 gene and one of the most challenging diseases to treat. Patients have a characteristic phenotype with neurofibromas as the main features in different forms, including numerous cutaneous neurofibromas, plexiform neurofibromas involving the primary nerves, or malignant peripheral nerve sheath tumors with a very short survival period after malignant transformation. NF1 patients also suffer from multi-system involvement, with a high rate of deformity and disability, making complete surgical resection more difficult. Currently, there is no consensus on the diagnosis and treatment of NF1 in China, and different disciplines have different understandings of NF1. Multidisciplinary systematic evaluations and cooperative treatments are the keys to improve the treatment, quality of life, and prognosis of NF1 patients. In 2020, the Department of Plastic Surgery of the Ninth People’s Hospital of Shanghai Jiaotong University School of Medicine led the establishment of the first multi-center collaboration group for NF1 in China. Furthermore, the group had worked with renowned experts from the various departments including surgical oncology, medical oncology, dermatology, reproductive medicine, et al. in China to formulate the “Expert consensus on diagnosis and management of neurofibromatosis type 1 (2021 edition)”, aiming to promote standardized and homogeneous treatment covering the whole life cycle of NF1 patients and improve the treatment level and outcome of NF1 patients in China.
