The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

Objective:To investigate the iodine nutrition status of key population in Fuzhou City, and to provide scientific basis for adjusting intervention strategies.Methods:From March to October 2021, a survey was conducted on iodine nutrition status of key population in 12 counties (cities, districts) of Fuzhou City. Each county (city, district) was divided into 5 sampling areas according to the east, west, south, north and middle directions. One township (street) was selected from each area, and 40 non-boarding children aged 8 - 10 (age balanced, half male and half female) from one primary school and 20 pregnant women (early, middle and late pregnancy balanced) were selected as survey subjects. Household salt samples and random urine samples were collected, and the salt iodine and urine iodine levels were tested by direct titration and arsenic and cerium catalytic spectrophotometry, respectively. Children's thyroid volume was measured by B-ultrasonography. At the same time, in cooperation with Fuzhou Maternal and Child Health Hospital, the thyroid stimulating hormone (TSH) testing results of heel blood of full-term natural delivery newborns in Fuzhou City in 2021 were collected.Results:A total of 2 400 children were monitored for salt iodine, urine iodine and goiter. The median salt iodine was 24.40 mg/kg, with an iodine salt coverage rate of 93.04% (2 233/2 400), a qualified rate of iodized salt of 97.40% (2 175/2 233), and a consumption rate of qualified iodized salt of 90.62% (2 175/2 400). The median urine iodine was 181.47 μg/L. The rate of goiter was 1.04% (25/2 400). A total of 1 200 pregnant women were monitored for salt iodine and urine iodine. The median salt iodine was 24.10 mg/kg, the coverage rate of iodized salt was 91.08% (1 093/1 200), the qualified rate of iodized salt was 97.90% (1 070/1 093), and the consumption rate of qualified iodized salt was 89.17% (1 070/1 200). The median urine iodine was 128.10 μg/L. The median TSH level in the heel blood of 14 242 newborns was 3.38 mU/L, and the proportion of TSH level > 5 mU/L was 30.96% (4 410/14 242).Conclusions:In 2021, children in Fuzhou City are at an appropriate level of iodine, but pregnant women are insufficient of iodine. We should continue to maintain comprehensive prevention and control measures mainly based on salt iodization, provide health education for pregnant women, and strengthen monitoring of TSH level in newborns.

The Chinese Guidelines on Diagnosis and Management of Atrial Fibrillation, jointly formulated by the Chinese Society of Cardiology, Chinese Medical Association and the Heart Rhythm Committee of Chinese Society of Biomedical Engineering, was first released on June 15, 2023.

This article interpreted the emergency management part in the guidelines in detail by reviewing relevant literature.

Objective:To learn about the implementation of various prevention and control measures after achieving the stage goal of eliminating iodine deficiency disorders (IDD) in Fuzhou City, and to evaluate the prevention and control effect.Methods:In September 2020, an assessment and evaluation was conducted on elimination of IDD in 12 counties (cities, districts) under the jurisdiction of Fuzhou City, with specific reference to the "Evaluation Content and Judgment Standards for Elimination of Iodine Deficiency Disorders" (2019 version). Using the target evaluation table for eliminating IDD, 4 management indicators of organizational and leadership, monitoring and prevention measures, iodized salt management and health education in 12 counties (cities, districts) from 2016 to 2020 were evaluated. Using stratified random sampling method, 2 townships/streets were selected from each county (city, district), and 20 pregnant women were sampled from each township/street. At the same time, two villages (neighborhood committees) were randomly selected from each township/street, and 20 children aged 8 - 10 (age balanced, half male and half female) were randomly selected from each village (neighborhood committee). The edible salt samples and instant urine samples of children and pregnant women were collected to detect the contents of salt iodine and urinary iodine; the iodine supplementation status of pregnant women was investigated by iodine supplementation rate questionnaire; the goiter in children was measured by B-ultrasound.Results:The management indicators scores of all 12 counties (cities, districts) were > 85 points, with an average score of 92.75 points. Changle District had the highest score (98 points), and Taijiang District had the lowest score (90 points). A total of 1 457 household salt samples were collected and tested in the city, including 967 samples from children aged 8 - 10 and 490 samples from pregnant women. The median salt iodine was 24.24 mg/kg, and the coverage rate of iodized salt was 93.62% (1 364/1 457). The qualified rate of iodized salt was 97.80% (1 334/1 364), and the coverage rate of qualified iodized salt was 91.56% (1 334/1 457). Except for Gulou District (88.33%, 106/120), Taijiang District (85.00%, 102/120), Mawei District (86.67%, 104/120), Changle District (89.34%, 109/122) and Minqing County (88.43%, 107/121), the coverage rate of qualified iodized salt was < 90%, the coverage rate of qualified iodized salt in the remaining counties (cities, districts) was > 90%. A total of 967 urine samples were collected from children, the median urinary iodine was 187.80 μg/L. The median urinary iodine of children in all counties (cities, districts) ranged from 140.08 to 269.70 μg/L. A total of 967 children were examined, and the goiter rate was 0.72% (7/967). The goiter rate ranged from 0 to 2.44% in all counties (cities, districts). A total of 490 urine samples were collected from pregnant women, with a median urinary iodine of 148.48 μg/L. Among them, the median urinary iodine of pregnant women in Gulou District (184.23 μg/L), Mawei District (262.85 μg/L), Jin'an District (176.80 μg/L), Luoyuan County (166.60 μg/L) and Yongtai County (157.62 μg/L) was > 150 μg/L, the median urinary iodine of pregnant women in other counties (cities, districts) was between 100 and 150 μg/L. A total of 490 pregnant women were investigated for iodine supplementation, the iodine supplementation rate was 94.90% (465/490). Except for Gulou District (85.00%, 34/40), Cangshan District (85.00%, 34/40) and Lianjiang County (87.50%, 35/40), the iodine supplementation rate < 90%, the iodine supplementation rate of pregnant women in other counties (cities, districts) was > 90%.Conclusions:The IDD prevention and control measures in Fuzhou City have been well implemented, and all counties (cities, districts) in Fuzhou City have maintained the state of eliminating IDD, and continued to consolidate the prevention and control achievements.

Liddle syndrome and Gordon syndrome are two rare single-gene inherited hypertension diseases. In patients≤40 years, the prevalence of Liddle syndrome is about 1% and Gordon syndrome is uncertain all over the word, for which is often misdiagnosed and mistreated. The therapies of those diseases are targeted at gene mutation sites, as well as combined with modified lifestyle, and can achieve satisfactory diseases control. This paper reports a patient who is diagnosed with Liddle syndrome and Gordon syndrome at the same time. We aimed to consolidate and improve the diagnosis and accurate treatment of those two diseases by sharing, studying and discussing together with clinical doctors.

ObjectiveTo study the accumulation and absorption of dry matter and nutrients in Curcuma phaeocaulis from Sichuan， the origin of Curcumae Radix （tuber） and Curcumae Rhizoma （rhizome）， to explore the growth and development laws and nutrient demand characteristics of the medicinal species， and thus to lay a theoretical basis for rational fertilization. MethodThe plant growth indexes， dry matter accumulation， and nutrient content of C. phaeocaulis at different growth stages in Sichuan were measured and analyzed. ResultThis medicinal species featured the dominant growth of aboveground leaves and stems before October and growth of underground part （particularly the rhizomes and tubers） from October. During the whole growth period， the accumulation of nitrogen， phosphorus， potassium， calcium， magnesium， iron， manganese， zinc， and copper per plant was 2 450.31， 907.09， 3 171.18， 625.94， 493.38， 14.53， 2.24 ， 2.93， 0.46 mg， respectively， with the order of potassium > nitrogen > phosphorus > calcium > magnesium > iron > zinc > manganese > copper. ConclusionThe species needs sufficient potassium and nitrogen， appropriate amount of phosphorus， calcium， and magnesium， a small amount of iron， and very little zinc， manganese， and copper for growth， and potassium is particularly important. Nitrogen， phosphorus， and potassium fertilizers supply macroelements and nitrogen fertilizer should be supplemented at seedling stage， leafy stage， early rhizome expansion stage， tuber expansion stage， and the second expansion stage of rhizome. Phosphorus and potassium fertilizers should be applied at seedling stage， tuber expansion stage， secondary expansion stage of rhizome， and dry matter accumulation stage of tuber and rhizome. At seedling stage， leafy stage， early rhizome expansion stage， tuber expansion stage， and the second expansion stage of rhizome， a variety of medium and trace elements-containing foliar fertilizers should be used.

The World Health Organization (WHO) released the WHO 2020 guidelines on physical activity and sedentary behaviour in November 2020. Compared with the 2010 WHO guidelines, this guideline has incorporated more extensive medical evidence and made targeted recommendations for special populations. The main content includes physical activity and sedentary behaviour advice for children and adolescents, adults, older adults, pregnant and postpartum women, people with chronic conditions, and disability. This review will interpret the 2020 WHO guidelines in detail.

Background: Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. Methods: Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. Results: The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. Conclusion The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

In order to effectively manage the atrial fibrillation patients, West China Hospital has established an integrated general-specialty management model within medical consortium. This model takes the atrial fibrillation-stroke integrated management outpatient clinic as the platform, combines general practice and specialty to provide standardized care for atrial fibrillation patients. The model was characterized by primary diagnosis, two-way referral, up and down linkage, and differential management for acute and chronic conditions. This article, taking West China Hospital as an example, introduces the integrated team of cardiologists and general practitioners in the tertiary hospital with general practitioners in the community, and the preliminary accomplishment in the management of atrial fibrillation within the medical consortium. It would provide a reference for the long-range management of atrial fibrillation in other provinces and cities.
