[Expert consensus on the diagnosis and treatment of respiratory diseases exacerbated by nonsteroidal anti-inflammatory drugs （2024, Chengdu）].

Non-steroidal anti-inflammatory drugs-exacerbated respiratory disease （N-ERD） is a chronic respiratory disease characterized by eosinophilic inflammation, featuring chronic rhinosinusitis （CRS）, asthma, and intolerance to cyclooxygenase 1 （COX-1） inhibitors. The use of these medications can lead to an acute worsening of rhinitis and asthma symptoms. This condition has not yet received sufficient attention in China, with a high rate of misdiagnosis and a lack of related research.

Chinese Expert Consensus on the Use of Biologics in Patients with Chronic Rhinosinusitis (2022, Zhuhai).

Background: Chronic rhinosinusitis (CRS) is a common inflammatory disease in otolaryngology, mainly manifested as nasal congestion, nasal discharge, facial pain/pressure, and smell disorder. CRS with nasal polyps (CRSwNP), an important phenotype of CRS, has a high recurrence rate even after receiving corticosteroids and/or functional endoscopic sinus surgery. In recent years, clinicians have focused on the application of biological agents in CRSwNP.

[Effects of simulated 5 500 m hypobaric and hypoxia on HPT axis and intestinal flora in rats].

To investigate the effects of simulated hypoxia environment at an altitude of 5 500 meters on hypothalamic-pituitary-thyroid (HPT) axis and intestinal flora of rats and the correlation between them. The hypoxia model of adult male SD rats was established by hypobaric chamber with simulated altitude of 5 500 m. The hypoxia groups were set for 1, 3, 7, 14, 21 and 28 days, and the normoxic recovery group were set for 1 and 3 days after hypoxia (8 rats per group, hypoxia time 24h per day).

[Effects of rapid and progressive ascent to Tibet plateau on cardiovascular function and stress factors of pre-selected expeditioners for Chinese Antarctic expedition for Kunlun station].

To explore the different effects of rapid and progressive ascent to Tibet plateau on cardiovascular function and stress factors in pre-selected expeditioners for the 31, 32 and 33 Chinese Antarctic expedition for inland station, to provide a scientific basis for the selection of qualified expeditioners. A total of 85 pre-selected expeditioners for the 31, 32 and 33 Chinese Antarctic expedition for Kunlun station were enrolled in this study. According to the different manners of entering the plateau, they were divided into the rapid ascent group by aircraft (RAG, =55) and the progressive ascent group by train (PAG, =30).

Hyperuricemia and clustering of cardiovascular risk factors in the Chinese adult population.

Hyperuricemia is common in China and the relevance of hyperuricemia and cardiovascular disease (CVD) risk has been highlighted, but to date there has been rarely nation-wide study in China. Here, we aim to estimate the current prevalence of hyperuricemia and evaluate the associations between hyperuricemia and cardiovascular risk factors (CRFs) clustering in a large sample of China adults including a plurality of ethnic minorities. Generally, a nationally representative sample of 22983 adults aged ≥18 years was recruited from 2007 to 2011.

[Effect of HIF-1alpha on sex hormone levels and germ cell apoptosis of mice].

Objective: To study the effect of hypoxia on hypothalamus-adenohypophysis-testis axis hormone levels, germ cell apoptosis and hypoxia-inducible factor-1alpha (HIF-1alpha) expression in testis of adolescent mice, and explore HIF-1alpha regulation on the reproductive function of male mice.

Methods: Eighty SPF grade adolescent C57BL/6 mice were randomly divided into normoxia group, hypoxia 3, 7, 14 and 28 d groups. The level of serum testosterone (T), free testosterone (FT), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) was analyzed by ELISA.

[Effects of different altitudes on cardiac hemodynamics and electrocardiogram of healthy male adults].

Objective: To detect the changes of cardiovascular system at different altitudes, so as to prevent and predict the susceptibility to acute mountain sickness.

Methods: The test was performed with noninvasive cardiovascular monitor and electrocardiogram in healthy male Chinese members of the 25th and 26th expeditions to the antarctic kunlun station at different altitudes (40 m, 3 650 m and 4 300 m).

Results: Compared with 40 m, from 3 650 m to 4 300 m, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), systemic vascular resistance (SVR), systemic vascular resistance index (SVRI) significantly increased (P < 0.

Reference data for quantitative ultrasound values of calcaneus in 2927 healthy Chinese men.

Quantitative ultrasound (QUS) is a bone densitometry technique that is rapidly gaining popularity for the assessment of bone status. However, few QUS data are available for men, especially in China. In the present study, a random stratified sample of 2927 Chinese men (10-90 years) was recruited, and bone status was established using measurements by Achilles ultrasonometer.

[Ultrasonic bone mineral density of calcaneus in 1 816 healthy subjects in Guangxi autonomous region].

Objective: To study the relationship between ultrasonic bone mineral density (BMD) of calcaneus and age, height, and body weight, and to establish the normal reference value for stiffness index (SI) of healthy subjects in Guangxi autonomous region and provide scientific foundation for the diagnosis and prevention of osteoporosis.

Methods: SI of calcaneus in 1 816 healthy adults aged 11-90 years (775 men, 1 041 women) were measured with quantitative ultrasound. According to their ages, all the men and women were divided into 13 groups by 5-year age group.

[Bone density of calcaneus of 2769 healthy persons in Zhejiang province].

Objective: To provide a scientific basis for the diagnosis and prevention of osteoporosis in Chinese populations.

Methods: The stiffness index (STI) of the calcaneus was measured with the Achilles Express ultrasound apparatus made in USA among 2769 healthy persons, 1262 males and 1507 females, aged 10 to over 60, in Zhejiang province. The relationships between the STI and sex and age were analyzed.

[Distribution of systemic vascular resistance disorders and its related factors in Hebei province].

Objective: To analyze the distribution features of systemic vascular resistance (SVR) disorder in healthy subjects in Hebei province.

Methods: SVR and systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), pulse pressure (PP), heart rate (HR), cardiac output (CO), cardiac index (CI), stroke volume (SV), stroke index (SI), left ventricular ejection time (LVET), left cardiac work (LCW) and cardiovascular function were determined with Bioz. com Cardio Dynamics.

[Analysis of the levels of serum total calcium and inorganic phosphate of 2,342 children in Beijing].

Objective: To study the changes of serum total calcium (Ca) and inorganic phosphate (P) levels during children growth and related factors.

Methods: Using a stratified-multi-steps-cluster sampling method, we selected 2,342 healthy children aged 10-18 years from urban and suburban areas of Beijing from September 2001 to December 2001 to test the levels of serum Ca and P. Their meal status was also surveyed to analyse the correlation of the leves of serum Ca and P with sex, age, height, weight, and diet on statistic basis.
