Kidney-Yang deficiency syndrome is a common geriatric disease that underlies chronic conditions such as diabetic nephropathy, chronic kidney disease, and osteoporosis. As age progresses, the kidney-Yang deficiency syndrome showcases increasingly pronounced manifestations, emerging as a key factor in the comorbidities experienced by elderly patients and affecting their quality of life and overall health status. Traditional Chinese medicine(TCM) has been extensively utilized in the treatment of kidney-Yang deficiency syndrome, with Epimedii Folium, Cinnamomi Cortex, and Lycii Fructus widely used in clinical settings. Despite the complexity of the molecular mechanisms involved in treating kidney-Yang deficiency syndrome, the potential therapeutic value of TCM remains compelling. Delving into the mechanisms of TCM treatment of kidney-Yang deficiency syndrome by regulating the neuro-endocrine-immune system can provide a scientific basis for targeted treatments of this syndrome and lay a foundation for the modernization of TCM. The pathophysiology of kidney-Yang deficiency syndrome involves multiple systems, including the interaction of the neuro-endocrine-immune system, the decline in renal function, the intensification of oxidative stress responses, and energy metabolism disorders. Understanding these mechanisms and their interrelationships can help untangle the etiology of kidney-Yang deficiency syndrome, aiding clinicians in making more precise diagnoses and treatments. Furthermore, the research on the specific applications of TCM in research on these pathological mechanisms can enhance the international recognition and status of TCM, enabling it to exert a greater global influence.

Transfusion-dependent thalassemia (TDT) is a severe genetic chronic hemolytic disease, and growth retardation is a common clinical feature in patients with TDT. Due to the need for regular blood transfusions, these patients often experience iron overload, which leads to various endocrine dysfunctions, including abnormalities in the growth hormone/insulin-like growth factor axis, hypothyroidism, hypoparathyroidism, hypogonadism, adrenal insufficiency, and decreased bone density. This paper reviews the clinical monitoring and intervention measures for growth disorders and related endocrine functions in patients with TDT, providing references for clinicians.

As a secondary endocrine organ, the liver is closely related to the endocrine system. Liver involvement is not uncommon in endocrine diseases, such as hyper/hypothyroidism, diabetes, dysfunction of adrenal and gonadal. It can be manifested in a variety of forms, including hepatocyte injury (elevated transaminase), bile duct injury (cholestasis), hepatocyte steatosis, vascular injury and liver tumor. Direct and indirect liver injury caused by abnormal hormone levels and side effects of drugs for the treatment of endocrine diseases are common pathogenesis. In addition, endocrine diseases can be concomitant with liver diseases, such as autoimmune thyroiditis and autoimmune hepatitis. Systemic diseases can also involve the endocrine system and liver at the same time, such as systemic lupus erythematosus and IgG4 related diseases. For patients with unexplained liver injury, endocrine system diseases should be considered as the differential diagnosis.

BACKGROUND: The industrial revolution has resulted in increased synthesis and the introduction of a variety of compounds into the environment and their potentially hazardous effects have been observed in the biota. The present study was aimed to evaluate the potential endocrine-disrupting effects of chronic exposure to the low concentrations of bisphenol S (BPS) in male rats. METHODS: Weaning male Sprague-Dawley rats (22 days old) were either exposed to water containing 0.1% ethanol for control or different concentrations of BPS (0.5, 5, and 50 μg/L) in drinking water for 48 weeks in the chronic exposure study. After completion of the experimental period, animals were dissected and different parameters (hormone concentrations, histology of testis and epididymis, oxidative stress and level of antioxidant enzymes in the testis, daily sperm production (DSP), and sperm parameters) were determined. RESULTS: Results of the present study showed a significant alteration in the gonadosomatic index (GSI) and relative reproductive organ weights. Oxidative stress in the testis was significantly elevated while sperm motility, daily sperm production, and the number of sperm in epididymis were reduced. Plasma testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) concentrations were reduced and estradiol levels were high in the 50 μg/L-exposed group. Histological observations involved a significant reduction in the epithelial height of the testis along with disrupted spermatogenesis, an empty lumen of the seminiferous tubules, and the caput region of the epididymis. CONCLUSION These results suggest that exposure to 5 and 50 μg/L of BPS for the chronic duration started from an early age can induce structural changes in testicular tissue architecture and endocrine alterations in the male reproductive system which may lead to infertility in males.

BACKGROUND: Particulate matter (PM), a major component of ambient air pollution, accounts for a substantial burden of diseases and fatality worldwide. Maternal exposure to PM during pregnancy is particularly harmful to children's health since this is a phase of rapid human growth and development. METHOD: In this review, we synthesize the scientific evidence on adverse health outcomes in children following prenatal exposure to the smallest toxic components, fine (PM RESULTS: Maternal exposure to fine and ultrafine PM directly and indirectly yields numerous adverse birth outcomes and impacts on children's respiratory systems, immune status, brain development, and cardiometabolic health. The biological mechanisms underlying adverse effects include direct placental translocation of ultrafine particles, placental and systemic maternal oxidative stress and inflammation elicited by both fine and ultrafine PM, epigenetic changes, and potential endocrine effects that influence long-term health. CONCLUSION Policies to reduce maternal exposure and health consequences in children should be a high priority. PM

To investigate the characteristics of the cold and heat properties of each resolution component of Açaí and the material basis of cooling by observing the effect of resolution components, such as Açaí oil, alcohol extract and water extract, on the neurotransmitter, endocrine hormone and immune factor level in mice with deficiency-heat and deficiency-cold syndrome. KM male mice were randomly divided into 12 groups, namely blank group, deficiency-heat model group, deficiency-heat+Açaí group, deficiency-heat+Açaí oil group, deficiency-heat+Açaí alcohol extract group, deficiency-heat+Açaí water extract group, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Açaí group, deficiency-cold+Açaí oil group, deficiency-cold+Açaí alcohol extract group, and deficiency-cold+Açaí water extract group. The mice in deficiency-heat group were given with thyroid tablet solution(160 mg·kg~(-1)), and the mice in deficiency-cold group were given with hydrocortisone solution(25 mg·kg~(-1)) by intragastric administration every afternoon for 14 days. The mice in each administration group received corresponding drug. The neurotransmitter, endocrine hormone and immune factor levels in the mice were measured after the experiment. The Açaí alcohol extract, consistent with the Açaí powder, showed a regulatory effect on the deficiency-heat model mice; Açaí oil and its water extract were consistent with Cinna-momi Cortex, showing a regulatory effect on the deficiency-cold model mice. In this study, on the basis of proving that Açaí was was cool in property, it also revealed that alcohol extract of Açaí was cool while oil and water extract were warm in property based on the effect of Açaí on neuro-endocrine-immune network. The results suggested that the medicine property of Açaí was the result of the comprehensive action of the resolution components with different properties, and the alcohol extract of Açaí was proved as the material basis of Açaí cold medicine by using the methods of homogeneous comparison and heterogeneous disproval.

The aim of this paper was to study the effect of Lepidium meyenii(Maca) on cyclic nucleotides, neurotransmitter levels and hypothalamic-pituitary-adrenal axis and immunization of deficiency-cold and deficiency-heat syndrome rats, in order to explore the cold and hot medicinal properties of Maca. SD rats were divided into blank group, deficiency-cold syndrome group, Cinnamomi Cortex of deficiency-cold syndrome(30 g·kg~(-1)) group, high and low-dose Maca groups(2.4, 1.2 g·kg~(-1)), deficiency-heat syndrome group, Phellodendri Chinensis Cortex(PCC) of deficiency-heat syndrome(5 g·kg~(-1)), and high and low-dose Maca groups(2.4, 1.2 g·kg~(-1)). The rats were treated with intramuscular injection of hydrocortisone(20 mg·kg~(-1)) or dexamethasone sodium phosphate(0.35 mg·kg~(-1)) for 21 days to set up the deficiency-cold and deficiency-heat model. The levels of cAMP, cGMP, NE, DA, 5-HT, CRH, ACTH, CORT and IgM, IgG, C3, C4 were detected by radio immunoassay. Both the high-dose Maca group and the low-dose Maca group can significantly improve the overall state and body weight of rats with deficiency-cold syndrome(P<0.01, P<0.05), significantly increasing cAMP, cAMP/cGMP, NE, DA, ACTH(P<0.01, P<0.001), and significantly decreasing 5-HT(P<0.01, P<0.001). However, high-dose and low-dose Maca groups could not improve the deficiency-heat syndrome, and the levels of cAMP, cGMP, cAMP/cGMP, NE, DA, 5-HT and ACTH were not statistically significant. Maca had a significant regulatory effect on CORT, IgM, IgG and C3 content of rats with deficiency-cold and deficiency-heat syndrome(P<0.01, P<0.05, P<0.001). Maca showed the same effect with Cinnamomi Cortex in adjusting the levels of deficiency-cold rats, but in opposition to Phellodendri Chinese Cortex. This paper confirmed that Maca was slightly warm based on its effect on cyclic nucleotide levels and neuro-endocrine-immune networks by the pharmacological experimental method.

The identification of disease-causing genetic variations is an important goal in the field of genetics. Advancements in genetic technology have changed scientific knowledge and made it possible to determine the basic mechanism and pathogenesis of human disorders rapidly. Many endocrine disorders are caused by genetic variations of a single gene or by mixed genetic factors. Various genetic testing methods are currently available, enabling a more precise diagnosis of many endocrine disorders and facilitating the development of a concrete therapeutic plan. In this review article, we discuss genetic testing technologies for genetic endocrine disorders, with relevant examples. We additionally describe our research on implementing genetic analysis strategies to identify novel causal mutations in hypocalcemia-related disorders.

Constipation is a common functional problem of the digestive system and may occur secondary to diet, drugs, endocrine diseases, metabolic diseases, neurological diseases, psychiatric disorders, or gastrointestinal obstruction. When there is no secondary cause, constipation is diagnosed as functional constipation. The first steps that should be taken to relieve symptoms are diet and lifestyle modifications, and if unsuccessful, laxative therapy should be initiated. If a patient does not respond to laxative therapy, diagnostic anorectal physiological tests are performed, though they are not routinely recommended. However, these tests may be considered earlier in patients strongly suspected to have a defecatory disorder. The revised guideline on the diagnosis and treatment of chronic constipation will undoubtedly aid the individualized management of chronic constipation in clinical practice.

Primary amenorrhea is a symptom with a substantial list of underlying etiologies which presents in adolescence, although some conditions are diagnosed in childhood. Primary amenorrhea is defined as not having menarche until 15 years of age (or 13 years with secondary sex characteristics). Various etiologies of primary amenorrhea include outflow tract obstructions, gonadal dysgenesis, abnormalities of the central nervous system, various endocrine diseases, chronic illnesses, psychologic problems, and constitutional delay of puberty. The management of primary amenorrhea may vary considerably depending on the patient and the specific diagnosis. In this article, the various causes, evaluation, and management of primary amenorrhea are reviewed with special emphasis on congenital sex hormonal disorders.
