Progress in diagnosis and treatment of pediatric diabetes in China PEI Zhou, LUO Feihong Journal of Diagnostics Concepts & Practice    2024, 23 (05): 461-466.   DOI: 10.16150/j.1671-2870.2024.05.001 Abstract （460）   HTML （22）    PDF（pc） （925KB）（361）       Knowledge map    Save The global incidence of type 1 diabetes mellitus (T1DM) in children and adolescents aged 0-19 years is about 1 211.9/10 million, with an incidence rate of 149.5/1 million person-years. In China, the incidence of T1DM in children and adolescents aged 0-19 years is about 56/1 million, with an incidence rate of 6.1/1 million person-years. The incidence of type 2 diabetes mellitus (T2DM) in children and adolescents has been rising annually. Epidemiological data shows that the incidence of T2DM among adolescents in the United States increased from 34/100 000 in 2001 to 46/100 000 in 2009 and to 67/100 000 in 2017. In China, the incidence of pediatric T2DM has also shown a significant upward trend, rising from 4.1/100 000 in 1995 to 10.0/100 000 in 2010. The diagnostic criteria for pediatric diabetes in China follow the standards set by the World Health Organization in 2019. Diabetes subtypes related to children include T1DM, T2DM, mixed-type diabetes, and other specific types of diabetes. The typical clinical manifestations of adult diabetes are polydipsia, polyuria, polyphagia, and weight loss (the ‘three P’s and one less’). However, in children with T1DM, these symptoms are more pronounced, while T2DM may present more subtly. Traditional treatment for T1DM primarily involves insulin therapy, but it cannot fundamentally address the issue of impaired pancreatic function. Preventing or delaying β-cell damage and protecting the remaining pancreatic function have become new research directions in T1DM treatment. In addition to traditional insulin therapy and lifestyle interventions, new treatments such as immunotherapy, artificial pancreas, and stem cell transplantation have shown promising clinical results. These advances not only provide new directions for the future treatment of diabetes but also have the potential to transform diabetes from an incurable disease into a treatable one.

Trends in global major disease burden and health conditions—interpretation of the Global Burden of Disease Study 1990-2021 FAN Bonan, LI Yan Journal of Diagnostics Concepts & Practice    2024, 23 (05): 474-483.   DOI: 10.16150/j.1671-2870.2024.05.003 Abstract （2051）   HTML （64）    PDF（pc） （3009KB）（4813）       Knowledge map    Save The Global Burden of Disease Study 2021 (GBD 2021) analyzed 371 diseases and injuries using 100,983 data sources, estimating years lived with disability, years of life lost, disability-adjusted life years, and healthy life expectancy. From 1990 to 2019, the annual rate of change in global all-cause mortality ranged from -0.9% to 2.4%, while deaths increased by 10.8% and 7.5% in 2020 and 2021 respectively due to COVID-19. In 2021, COVID-19 was the second lea-ding cause of death globally, with a mortality rate of 94.0 per 100 000. The mortality rates of other major causes, such as ischemic heart disease and stroke were 108.7 and 87.4 per 100 000, respectively. Global life expectancy rose from 65.5 years in 1990 to 73.3 years in 2019 but dropped to 71.7 years in 2021 due to COVID-19, which reduced life expectancy by 2.2 years, significantly impacting the trend of health improvement. In China, GBD 2021 data shows a significant increase in life expectancy from 1990 to 2021: from 69.9 to 80.7 years for women and from 65.7 to 74.9 years for men. However, non-communicable diseases such as cardiovascular diseases, cancers, and chronic respiratory diseases remain major health threats. In 2021, these diseases had the highest burden among the top ten causes in China, with rising incidence and morta-lity rates. Major health risk factors in China include tobacco, hypertension, and dietary risks. This paper, through the systematic analysis of GBD 2021 data, reveals current trends in disease burden globally and in China, and proposes public health strategy recommendations. China should enhance chronic disease management, improve public health emergency responses, address health inequalities, and promote basic research and international cooperation to improve overall health levels.

Differential diagnosis and treatment of thyroid storm YAN Huixian, LÜ Chaohui Journal of Diagnostics Concepts & Practice    2024, 23 (04): 354-361.   DOI: 10.16150/j.1671-2870.2024.04.002 Abstract （433）   HTML （17）    PDF（pc） （1282KB）（660）       Knowledge map    Save Thyroid storm is a rare, life-threatening endocrine emergency characterized by severe clinical manifestations of thyrotoxicosis. Studies in the United States and Japan show that the annual incidence rates of hyperthyroid storm are (0.57-0.76) per 100 000 people and 0.2/100 000 people, respectively, accounting for 0.22% of all hyperthyroid patients and 5.4% of hospitalized hyperthyroid patients. Even with timely treatment, the mortality rate of patients with hyperthyroidism storm is still as high as 10%-30%; If left untreated, the mortality rate of patients may reach 90%. The misdiagnosis and missed diagnosis rate of hyperthyroidism storm in the Emergency Department is as high as 43.48%. It may be precipitated by abrupt discontinuation of antithyroid drugs or by an acute event such as infection, trauma, thyroid or nonthyroidal surgery, an acute iodine load, or parturition and other rare causes. There are currently no recognized standards or validated clinical tools for diagnosing thyroid storm. The diagnosis of thyroid storm is based upon the presence of biochemical evidence of hyperthyroidism (elevation of free T4 and/or T3 and suppression of TSH), and severe and life-threatening symptoms (hyperpyrexia, cardiovascular dysfunction, and altered mentation). BWPS has been widely used for the identification of thyroid storm for nearly 30 years. The main treatments for thyroid storm consist of symptomatic treatment and specific treatment for the thyroid gland, including removing the cause and treating complications cuse of thionamide, iodine, glucocorticoids and beta-blockers to inhibit new hormone synthesis, block the peripheral conversion of T4 to T3, inhibition of the release of thyroid hormone. If the above treatment do not improve the condition, blood purification therapy (plasmapheresis) can be tried. In addition to specific therapy directed against the thyroid, supportive therapy is essential. After active treatment, most of the status of patients with thyroid storm are improved within 1 to 2 days. After a successful rescue of thyroid storm, hyperthyroidism should be treated by radical treatment. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Current status and challenges in ultrasound diagnosis and treatment of thyroid nodules in China ZHOU Jianqiao, ZHANG Lu, XU Shangyan Journal of Diagnostics Concepts & Practice    2024, 23 (04): 362-370.   DOI: 10.16150/j.1671-2870.2024.04.003 Abstract （429）   HTML （20）    PDF（pc） （1012KB）（1097）       Knowledge map    Save Thyroid nodules (TNs) exhibit a high prevalence rate of 36.9% in China, with a marked preponderance in females over males, and regional variations observed. Ultrasonography (US), due to its non-invasiveness, convenience, and high sensitivity, has emerged as the primary diagnostic tool for TNs. In recent years, advancements in US diagnostic techniques have flourished, including the Thyroid Imaging Reporting and Data System (TIRADS), multimodal US, fine-needle aspiration (FNA) coupled with molecular testing, and artificial intelligence (AI). Notably, the 2020 edition of the Chinese-specific C-TIRADS system has improved diagnostic accuracy by tailoring to China's healthcare landscape. Multimodal US assessment, integrating various US techniques, has significantly enhanced diagnostic efficacy, reducing unnecessary biopsies. Molecular testing and AI-assisted diagnosis have further improved diagnostic precision; however, the generalization capabilities of AI models and their long-term clinical application efficacy remain to be validated. Ultrasound-guided interventional therapies occupy a pivotal position in TN management, including chemical ablation and thermal ablation techniques. Chemical ablation is primarily utilized for cystic-predominant nodules, whereas thermal ablation is suitable for both cystic-solid and solid nodules, with their combined application yielding optimal results. Although the application of thermal ablation in thyroid micropapillary carcinoma remains controversial, preliminary studies have demonstrated its efficacy and safety. Despite the remarkable progress in US technologies for TN diagnosis and treatment, challenges persist, including inconsistent diagnostic criteria, disparities in equipment and technical expertise across regions and hospitals, and the absence of large-scale studies on the long-term efficacy and safety of thermal ablation. Future directions encompass refining risk stratification systems, intensifying research on multimodal US assessment, enhancing the generalization capabilities of AI models, standardizing the application of molecular testing, exploring indications for ablation therapy, and establishing standardized efficacy assessments.

Interpretation of cancer death burden data from disease surveillance sites in China from 2005 to 2020 ZHANG Xin, ZHENG Ying Journal of Diagnostics Concepts & Practice    2024, 23 (04): 371-377.   DOI: 10.16150/j.1671-2870.2024.04.004 Abstract （379）   HTML （39）    PDF（pc） （1154KB）（1086）       Knowledge map    Save In December 2023, the Chinese Center for Disease Control and Prevention published National and subnational trends in cancer burden in China, 2005-2020: an analysis of national mortality surveillance data.on Lancet Public Health, covering the mortality rate and average years of life lost from 23 specific tumor sites in people in 31 provinces and cities across the country. The analysis suggests that in 2020, the number of deaths from cancer in China was 2.3978 million, with a mortality rate of 170.80/100 000. The top 10 tumor deaths cases are as follows: lung cancer 761,000, liver cancer 367,700, stomach cancer 291,200, colorectal cancer 182,400, esophageal cancer 173,300, pancreatic cancer 100,400, breast cancer 57,100, leukemia 54,900, cranial nerve cancer 54,200, cervical cancer 44,800, accounting for 32.0%, 15.3%, 12.1%, 7.6%, 7.2%, 4.2%, 2.4%, 2.3%, 2.3%, 1.9% of the total number of deaths due to tumors, respectively. The mortality rates were 54.57/100 000, 26.19/100 000, 20.74/100 000, 13.00/100 000, 12.34/100 000, 7.15/100 000, 4.06/100 000, 3.91/100 000, 3.86/100 000 and 3.19/100 000, respectively. In 2020, the average years of life lost (AYLL) due to cancer in China was 23.60 years, which was 3.74 years lower than that in 2015. Among them, leukemia caused an AYLL of 37.35 years, with a decrease of 13.36 years from the AYLL of 50.71 years caused by leukemia in 2005, but it was still the tumor that caused the most life loss. Prostate cancer was the tumor that caused the least AYLL. The composition of China’s cancer spectrum is changing to those in developed countries. Lung cancer, breast cancer and colorectal cancer, which are highly prevalent in developed countries, are showing an increasing disease burden trend in China. In 2020, the mortality rates of lung cancer, breast cancer and colorectal cancer all increased during this period, increasing by 78.98%, 19.41% and 47.56% respectively compared with those in 2005. GLOBOCAN2022 suggests that the top 10 cancer incidence rates in China in 2020 are lung cancer (40.8/100 000), breast cancer (33.0/100 000), thyroid cancer (24.6/100 000), liver cancer (20.1/100 000), cervical cancer (15.0/100 000), gastric cancer (13.8/100 000), prostate cancer (13.7/100 000), esophageal cancer (9.7/100 000), uterine cancer (8.7/100 000) and ovarian cancer (6.8/100 000). Five of the top 10 common cancer in China and the United States overlap, and lung cancer is the leading cause of death in both countries. Changes in the spectrum of tumor diseases have made the promotion and implementation of proven tumor prevention and control measures more urgent.

Current status and challenges in diagnosis and treatment of systemic lupus erythematosus in China ZHANG Xin, ZHAO Shengnan, FENG Xuebing Journal of Diagnostics Concepts & Practice    2024, 23 (03): 257-262.   DOI: 10.16150/j.1671-2870.2024.03.002 Abstract （2011）   HTML （45）    PDF（pc） （923KB）（1184）       Knowledge map    Save Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by multiple system involvements. The number of SLE patients in China is large, and patients suffer more severe condition, with low remission rate ，high recurrence rate ，and high risk of infection.The situation of diagnosis and treatment for SLE is still serious. Relevant research released in 2023 shows that there are about 3.41 million cases of SLE patients in the world,and the number of patients in China amounts to 700 000-1 000 000, ranking the first in the world. The average onset age of SLE patients in China is 30.7 years old, and the incidence ratio of women to men is 12∶1.Organ involvement is more common in China, with 45.02% of renal involvement and 37.2% of haematological involvement, which are significantly higher than those in European patients with SLE (27.9% of renal involvement and 18.2% of haematological involvement). The clinical remission rate of SLE patients in China is 2.47%，while the relief rate reported internationally is 22.9%. Currently, the short-term survival rate of SLE patients in China is basically in line with that in the world (5-year survival rate reach 94%), but the long-term survival rate is still not optimistic, declining sharply, with a 25-30 year survival rate of only 30%. In China, 84.13% of SLE patients receive glucocorticoid（GC）therapy, while 42.6% SLE patients receive GC in the world. Infection is the leading cause of death for SLE patients in China, while in western countries, the main causes of death for SLE patients are cardiovascular disease and tumors With the proposal of new classification standards, the introduction of the concept of up-to-date treatment, as well as the use of new treatment methods, the development of SLE diagnosis and treatment will be greatly promoted, and it is expected to further improve the prognosis of patients in China.

Advances in study on diagnosis and treatment of immune-mediated necrotizing myopathy LIU Hongjiang, XIE Qibing Journal of Diagnostics Concepts & Practice    2024, 23 (03): 270-277.   DOI: 10.16150/j.1671-2870.2024.03.004 Abstract （1277）   HTML （24）    PDF（pc） （935KB）（1666）       Knowledge map    Save Immune-mediated necrotizing myopathy (IMNM) is a significant, subtype of idiopathic inflammatory myopathy（IIM）, characterized by symmetrical proximal limb muscle weakness and markedly elevated serum creatine kinase levels. Some patients may also exhibit extra-skeletal muscle manifestations, including rashes, interstitial lung disease, and myocardial involvement. Since its international nomenclature in 2003, IMNM has gained increasing recognition among researchers and clinicians, leading to numerous scientific investigations and clinical applications. The incidence and prevalence of IMNM can vary across different geographic regions and ethnic groups. A small sample survey conducted in the United States reported an incidence of 0.83 per 100,000 and a prevalence of 1.85 per 100,000. In northern Spain, among patients positive for anti-HMGCR antibodies, the incidence was found to be 0.6 per 100,000, with a prevalence of 3 per 100,000. However, there is a notable paucity of relevant data regarding IMNM in China. Identified risk factors for IMNM include susceptibility alleles (e.g., HLA-DRB1*11), the use of statins or immune checkpoint inhibitors, and viral infections. Diagnosing IMNM requires a comprehensive evaluation that includes assessing muscle involvement symptoms, identifying myositis-specific autoantibodies, measuring creatine kinase levels, analyzing muscle biopsy pathology, and conducting related examinations. Currently, there is a lack of prospective randomized controlled studies on the treatment of IMNM. In clinical practice, glucocorticoids and traditional immunosuppressants are primarily employed on an empirical basis. For refractory cases, treatment regimens may involve rituximab and intravenous human immunoglobulin. Therapeutic strategies targeting B cells and the mechanisms underlying pathogenic autoantibody production may offer promising avenues for future treatment. This article systematically reviews the clinical characteristics, diagnostic criteria, relevant auxiliary examinations, and treatment strategies for IMNM, aiming to provide a comprehensive reference for clinicians in understanding, diagnosing, and managing this condition.

The consensus on the diagnosis and treatment of elderly myelodysplastic neoplasm in China (2024) MDS Professional Committee of Hematology Branch of Chinese Geriatrics Society Journal of Diagnostics Concepts & Practice    2024, 23 (03): 285-296.   DOI: 10.16150/j.1671-2870.2024.03.006 Abstract （2091）   HTML （92）    PDF（pc） （1106KB）（5383）       Knowledge map    Save Myelodysplastic syndromes (MDS) are a heterogeneous group of myeloid tumours originating from haematopoietic stem/progenitor cells, with a high prevalence in the elderly. Epidemiological surveys in Europe and the United States have revealed that the incidence of MDS is (4-5)/100 000, which increases with age，and the median age at diagnosis of MDS patients reaches 73-76 years. In Shanghai, China, according to the World Health Organization (WHO) 2008 diagnostic criteria, the average incidence rate was 1.51/100 000, and the median age of onset of MDS was found to be 62 years old in a survey conducted in 3.9 million people from 2004 to 2007, of which about one-third of the patients would be transformed into acute myeloid leukemia (AML), and 53% of the patients would die due to infections, haemorrhages, or comorbidities triggered by cytopenias. Elderly MDS patients have their own characteristics in terms of both treatment choices and disease prognosis due to more comorbidities and weaker health. Clinical characteristics of elderly MDS patients include slightly higher white blood cell count, haemoglobin level and more bone marrow blasts than those of young patients, while neutrophil count and platelet count are significantly higher than those of young patients; the number of mutations in elderly MDS patients is higher, with an average of 1.8 mutations per patient, among which the mutations in ASXL1, TET2, SF3B1, STAG2, SRSF2 and TP53 are more common; while the number of mutations in younger patients averages 1.2 per person, among which U2AF1, ASXL1 and RUNX1 mutations are more common. Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is the only curative treatment for MDS, and myeloablative transplantation is feasible in young patients, but only reduced-intensity conditioning (RIC) allo-HSCT can be performed in elderly patients.The natural course and prognosis of elderly MDS patients varies considerably, and the MDS Composite Prognostic Score, which is composed of the composite age (>70 years old), vulnerability index, and IPSS prognostic subgroups, is able to better predict the tolerance of chemotherapy and adverse treatment effects in MDS patients. This consensus is based on the latest evidence-based data in the study of MDS in the elderly at home and abroad, and has been discussed by the experts of the group, which aims to standardise the diagnosis and the whole management of treatment for elderly MDS patients in China.

Summary and interpretation of the World Health Organization “Global Report on Hypertension” ZHANG Dongyan, LI Yan Journal of Diagnostics Concepts & Practice    2024, 23 (03): 297-304.   DOI: 10.16150/j.1671-2870.2024.03.007 Abstract （3018）   HTML （75）    PDF（pc） （945KB）（5573）       Knowledge map    Save In 2023, the World Health Organization (WHO) released the first document of “Global report on hypertension—The race against a silent killer”. which covers the global prevalence and management of hypertension, analyzes the mortality and disease burden caused by hypertension, explores the risk factors for hypertension, evaluates the cost-effectiveness of blood pressure treatment, and presents successful examples of hypertension management in many countries, especially the global implementation of the WHO-launched HEARTS project for hypertension control. Hypertension is a significant global public health challenge with severe health implications. Over the past 30 years, the number of people with hypertension (defined as systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, or taking antihypertensive medication) has doubled, rising from 650 million in 1990 to 1.3 billion in 2019. Among the global hypertensive population aged 30-79, approximately 54% have been diagnosed, of which 42% are receiving antihypertensive treatment, and only 21% have controlled blood pressure. In 2019, elevated systolic pressure was responsible for over half of cardiovascular disease deaths globally. Increasing the global hypertension control rate to 50% could prevent 76 million deaths from 2023 to 2050. Population-level risk factors for hypertension include high salt and low potassium intake, alcohol consumption, physical inactivity, and air pollution. WHO advocates for the prevention and control of hypertension through measures such as reducing dietary sodium intake, increasing potassium intake, limiting alcohol consumption, quitting smoking, increasing physical activity, and improving air quality. In terms of treatment, WHO guidelines recommend antihypertensive medication for individuals with systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg. For specific populations, it is also recommended to start antihypertensive treatment when systolic blood pressure is between 130-139 mmHg. The use of single-pill combination therapy is also advised to improve adherence and persistence in treatment. The prevalence and management of hypertension in China are also noteworthy. Hypertension is a major cause of mortality and disease burden in the Chinese population. By learning from global successes in hypertension management, China can enhance its efforts in the prevention, control, and monitoring of hypertension, particularly by promoting the application of the HEARTS technical package to improve hypertension management. This report aims to draw attention to major non-communicable diseases, particularly hypertension, as a public health challenge. Through detailed data analysis and successful case studies, the report underscores the importance of hypertension prevention and control, providing scientific evidence for policy-making across countries. This collective effort aims to achieve the global goal of a 25% relative reduction in uncontrolled hypertension prevalence by 2025 compared to 2010. This article will interpret briefly the reports based on the prevalence and management of hypertension in China. Table and Figures | Reference | Related Articles | Metrics | Comments（0）

Interpretation on the report of global stroke data 2022 TANG Chunhua, GUO Lu, LI Qiong, ZHANG Lili Journal of Diagnostics Concepts & Practice    2023, 22 (03): 238-246.   DOI: 10.16150/j.1671-2870.2023.03.06 Abstract （7803）   HTML （304）    PDF（pc） （2270KB）（7661）       Knowledge map    Save In 2022, the World Stroke Organization released two new reports regarding global stroke statistics in the International Journal of Stroke. The reports updated the global incidence and mortality of stroke, evaluated the effects of gender and geographic factors, and provided updated statistics on attributable risk factors associated with stroke. This article briefly interprets the two reports in the context of stroke prevalence and disease burden in China. 2019 Global Burden of Disease Study findings show that stroke remains the second-leading cause of death and the third-leading cause of death and disability combined in the world. From 1990 to 2019, the burden (in terms of the absolute number of cases) increased substantially, with the bulk of the global stroke burden residing in lower-income and lower-middle-income countries. Moreover, people under 70-year-old were observed to have significant increases in stroke prevalence and incidence. The five major risks for stroke globally include high systolic blood pressure, high body mass index, high fasting glucose, environmental particulate matter pollution, and smoking. Stroke prevention and treatment in China are facing great challenges. Stroke has become the leading cause of death and disability among Chinese adults, as well as the leading cause of disability adjusted life year lost. The incidence, prevalence and mortality of stroke in China are geographically high in the north, low in the south and prominent in the central part of the country; the prevalence is higher in rural areas than that in urban areas; the morbidity and mortality rates are higher in men than those in women; the average age of onset is lower than in developed countries; the overall disease burden of ischemic stroke is on the rise, but that of hemorrhagic stroke is on the decline. The awareness of stroke prevention and treatment was low. In conclusion, it is of strategic importance to actively establish a graded stroke prevention and control system that meets the national conditions.

In 2021, WHO approved a total of six molecular diagnostic technologies for TB diagnosis and anti-TB drug resistance detection, and three new TB antigen-based skin tests for TB screening were recommended. To reduce the burden on patients and the health system, WHO recommends a 4-month regimen for drug-susceptible TB and four shorter regimens for the treatment of multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB). In addition, there were 26 drugs for TB treatment in clinical trials, and at least 22 clinical trials evaluating drugs and drug regimens for TB treatment were underway. In 2021， the TB epidemic remains severe in China, with the number of newly diagnosed cases ranking third among the 30 countries. In 2021, a total of 639 548 TB cases and 1 763 deaths were reported nationwide, with an incidence of 45.37/100 000 and a mortality of 0.13/100 000. China has the fourth largest number of MDR/RR-TB patients in the world. However, it is necessary to verify whether the regimens for MDR/RR-TB treatment recommended by WHO are suitable for patients in China.
