A rapid and concise dual-mode aptasensor for ultrasensitive detection of 17β-estradiol

Zhao Fengfeng

Objective: Pollution of endocrine disrupting chemicals has become a global issue. As one of the hormonally active compounds, 17β-estradiol produces the strongest estrogenic effect when it enters the organism exogenously including food intakes, bringing potential harmfulness such as malfunction of the endocrine system. Therefore, in order to assure food safety and avoid potential risks of 17β-estradiol to humans, it is of great significance to develop rapid, sensitive...

Thyrotropin/Thyrotropin receptor signaling deficiency impairs spatial learning and memory

Luan Sisi , Hou Xu , He Zhao , Zhao Jiajun

Purpose: Subclinical hyperthyroidism is associated with cognitive impairment, but the mechanism has remained unclear. As subclinical hyperthyroidism is characterized by significantly decreased thyrotropin (TSH) levels, this study aimed to investigate whether TSH regulates cognitive function.Methods: The correlation between TSH and cognitive impairment was investigated in a cross-sectional population study including 382 participants wi...

Factors associated with dysglycemia and its post-surgical resolution in patients with Pheochromocytomas and Paragangliomas

Zhao Lin , Liu Yecheng , Zhou Xianliang

Background: Pheochromocytomas and paragangliomas (PPGLs) are a group of rare neuroendocrine tumors. Dysglycemia has been observed in patients with PPGLs in some small case series. However, few large studies, and none in China, have described the outcomes of dysglycemia after resection, and the factors associated with the development and resolution of dysglycemia in patients with PPGLs.Methods: We retrospectively analyzed the clinical data of consecutive ...

Levonorgestrel inhibits human endometrial cell proliferation through the up-regulation of gap junctional intercellular communication via the increased expression of Connexin43 and the nuclear translocation of its Ser255 phosphorylation

Zhao Xiaomiao , Tang Xuelian , Xie Meiqing

Context: Gap junction intercellular communication (GJIC) and its constructed protein Connexin (Cx) participates in cell apoptosis and tumorigenesis. Our clinical studies demonstrated that a levonorgestrel (LNG)-releasing intrauterine system can reverse atypical endometrial hyperplasia.Objective: This study assesses whether LNG exerts anti-proliferation effects on human endometrial cells through changes in the GJIC function and Cx43 expression.<p clas...

Challenges in diagnosis and management of silent corticotroph adenomas: insights from three case studies and literature review

Zhao Xinyi , Li Zhenyi , Wang Chun

Silent Corticotroph Adenomas (SCAs) are a type of pituitary tumor that is discovered without obvious clinical symptoms. SCAs are considered to be one of the five "high-risk" tumors due to their aggressive behavior, characterized by high levels of proliferation, rapid progression, and recurrence. Unlike functional corticotropin adenomas, SCAs do not exhibit any clinical or biochemical signs of hypercortisolemia. When the tumor is detected, it often exhibits invasive gro...

The effects of BPA exposure on fat mass and serum leptin concentrations have no impact on bone mineral densities in non-obese premenopausal women.

Liu J. , Zhao H. , Bi Y. , Ma L. , Zhang L. , Zhao L. , Tao B. , Sun L. , Wang T. , Zhao Y. , Wang W. , Xu M. , Chen J. , Ning G.

Objective: Bisphenol A (BPA) exposure may promote obesity, but its effect on bone mineral density (BMD) has not been reported in humans. In the present study, we aimed to examine the complex interplay between BPA exposure, fat mass, fat-free mass, serum estradiol, leptin, osteocalcin levels and BMDs in a group of premenopausal women.Methods: A total of 246 Chinese premenopausal women aged 20 years and older with regular menstrual cycles were investigated...

Morning cortisol and circulating inflammatory cytokine levels: a mendelian randomisation study

Rajasundaram Skanda , Rahman Rezbieara , Woolf Benjamin , Zhao Steven , Gill Dipender

Background: Cortisol is an essential steroid hormone released from the adrenal gland. Plasma cortisol levels follow a circadian rhythm under the control of the Hypothalamic–Pituitary–Adrenal axis, reaching peak levels in the morning. Cortisol has long been known to exert immunosuppressive effects and accordingly, glucocorticoids are central in treating inflammatory disease. Cortisol’s propensity to downregulate certain pro-inflammatory cytokines and upregulate o...

Effects of Diabetes on Clinical Outcomes of Psoriatic Patients With Coronary Artery Disease

Zhao Lin , Sun Lin , Zeng Yan , Zhou Xianliang

Background: Psoriasis is associated with a heightened prevalence of cardiovascular risk factors, including diabetes. However, it is not clear whether diabetes will cause differences on clinical outcomes of psoriatic patients who have already suffered from coronary artery disease.Methods: We conducted a retrospective cohort study of consecutive psoriatic patients with coronary artery disease between January 2017 and May 2022 in our hospital. The clinical ...

Effects of Metabolic Syndrome on Cardiovascular Outcomes of Psoriatic Patients With Coronary Artery Disease

Zhao Lin , Sun Lin , Zeng Yan , Zhou Xianliang

Background: Psoriasis is associated with a heightened prevalence of cardiovascular risk factors, including metabolic syndrome (MetS). As so far, it is not clear whether MetS will cause differences on clinical outcomes of psoriatic patients who have already suffered from coronary artery disease.Methods: We conducted a retrospective cohort study to determine the effects of MetS in psoriatic patients with coronary artery disease. Comparisons were made betwe...

Prolonged exposur to methylprednisolone disrupt the rat adrenal gland steroidogenic pathway and affect intra-adrenal inflammatory mediators

Spiga Francesca , Zhao Zidong , Li Yanyu , Lightman Stafford

Pharmacological treatment with synthetic glucocorticoids, which are widely prescribed for the treatment of numerous inflammatory and autoimmune diseases, can also affect the way the adrenal gland produces cortisol. Indeed, patients undergoing synthetic glucocorticoid treatment can develop adrenal insufficiency. This condition is characterised by reduced responsiveness of the adrenal to ACTH stimulation, and adrenal crisis/shock can occur in response to acute physiological stre...
