Objective:To determine the incidence of adrenal incidentalomas(AIs) in patients with diabetes mellitus and the metabolism profiles.Methods:A total of 615 hospitalized patients with diabetes mellitus in the Department of Endocrinology and Metabolism of Peking University People′s Hospital from March 2020 to May 2021 were retrospectively included in this study. AIs were screened by unenhanced chest computed tomography(CT) retrospectively and subsequently confirmed by multiplanar reconstruction. Participants′ physical indicators, metabolic profiles, and adrenal function parameters were collected. Unpaired t test, Mann-Whitney U test, and Chi-Square test were adopted to compare the metabolism profiles between diabetes mellitus patients with or without AIs. Regression models were used to estimate the correlations between AIs and the metabolism profiles such as blood glucose, blood lipids, blood pressure, and the adrenal function parameters.Results:Twenty-seven out of 615 participants were detected with AIs(4.4%). Patients with AIs had higher body mass index, waist circumference, and hip circumference than patients without AIs [(29.4±5.1)kg/m 2vs(26.8±3.8)kg/m 2,P=0.018; (102.3±11.7)cm vs(95.8±10.3)cm, P=0.002; (107.3±10.1)cm vs(101.4±7.6)cm, P=0.008]. The levels of serum uric acid and urinary albumin/creatinine ratio were also significantly increased in patients with AIs [(409.6±118.1)μmol/L vs(357.4±100.6)μmol/L, P=0.009; 21.25(7.49, 180.24)mg/g vs 8.60(4.71, 34.56)mg/g, P=0.010]. Besides, individuals with AIs were also associated with a higher risk of co-existing hypertension( P=0.045). Conclusion:The incidence of AIs in patients with diabetes is 4.4%. The presence of AIs in patients with diabetes may associated with increased risk of obesity and hypertension.

Introducción: El desarrollo de la tolerancia inmunológica frente a los autoantígenos se denomina autotolerancia. La Diabetes Mellitus tipo 1A (1ADM) es un trastorno metabólico secundario a la destrucción autoinmune de las células beta pancreáticas e insulitis. La miastenia grave (MG) es una enfermedad autoinmune causada por el bloqueo postsináptico de la placa mioneural por AAcs contra los receptores de acetilcolina (ACRA) o contra moléculas de la membrana postsináptica. La asociación entre DM1A y MG se puede observar en el síndrome poliglandular tipo III, caracterizado por enfermedad autoinmune de la glándula tiroides asociada con otras entidades autoinmunes. Método: Reporte de Casos, cuatro pacientes entre 7-19 años, con asociación de MG y DM1A atendidos en el Hospital Garrahan. Conclusión: La Tiroiditis de Hashimoto y la Enfermedad Celíaca son las enfermedades autoinmunes relacionadas más frecuentemente con DM1A en nuestra población. La bibliografía describe la asociación de MG y Tiroiditis de Hashimoto y su coexistencia con DM1A se describe en el Síndrome Poliglandular III. En este trabajo presentamos 4 casos de DM1A asociado con MG fuera de dicho síndrome (AU)
Introduction: The development of immune tolerance to autoantibodies (AAbs) is referred to as self-tolerance. Type 1A Diabetes Mellitus (1ADM) is a metabolic disorder secondary to autoimmune destruction of pancreatic beta cells and insulitis. Myasthenia gravis (MG) is an autoimmune disease caused by postsynaptic blockade of the myoneural plate by AAbs against acetylcholine receptors (Acra) or against postsynaptic membrane molecules. The association between 1ADM and MG may be observed in polyglandular syndrome type III, characterized by autoimmune disease of the thyroid associated with other autoimmune conditions. Methods: Case report; four patients between 7-19 years old, with an association of MG and 1ADM seen at the Garrahan Hospital. Conclusion: Hashimoto's thyroiditis and celiac disease are autoimmune diseases most frequently related to 1ADM in our population. In the literature, the association of MG and Hashimoto's thyroiditis has been described and its coexistence with 1ADM is reported in polyglandular syndrome III. In this study we present 4 cases of 1ADM associated with MG unrelated to this syndrome. (AU)

OBJECTIVES@#To study the association between early-life factors (including birth weight, method of birth, gestational age, and history of gestational metabolic disorders) and pubertal timing in girls.@*METHODS@#The stratified cluster sampling method was used to select the girls in grades 2-3 and 7-8 from three primary schools and three middle schools in Guangzhou, China from March to December, 2019, and breast development was examined for all girls. A questionnaire survey was performed to collect the information on early-life factors. The multivariate logistic regression model was used to evaluate the association of gestational metabolic disorders, birth weight, method of birth, and gestational age with pubertal timing in girls. The Bootstrap method was used to assess the mediation effect of body mass index (BMI) (Z score) between high birth weight (≥4 000 g) and pubertal timing.@*RESULTS@#A total of 1 665 girls were enrolled, among whom 280 (16.82%) were judged to have early pubertal timing. The multivariate logistic regression analysis showed that high birth weight was associated with the increased risk of early pubertal timing (OR=2.12, 95%CI: 1.19-3.66, P=0.008). Nevertheless, no significant association was observed between other early-life factors and pubertal timing (P>0.05). The OR for the mediation effect of BMI (Z score) between high birth weight and early pubertal timing was 1.25 (95%CI: 1.09-1.47), accounting for 29.33% of the total effect of high birth weight on early pubertal timing.@*CONCLUSIONS@#High birth weight is associated with the increased risk of early pubertal timing in girls, and overweight/obesity may play a partial mediating role in the association between high birth weight and early pubertal timing in girls.

Introduction: Urolithiasis has increased in recent decades. Autosomal dominant polycystic kidney disease (ADPKD), the most common of all hereditary kidney diseases, occupies a predominant position in terms of incidence. Objectives: Identify the frequency of occurrence of urinary metabolic disorders in Cuban urolithiasis patients with and without ADPKD. Methods: A descriptive cross-sectional study was conducted of 579 adult patients without ADPKD selected by simple random sampling, and 21 patients with ADPKD, from the total urolithiasis patients undergoing renal metabolic evaluation at the Renal Physiopathology Laboratory of the Institute of Nephrology in the period 2010-2015. Data were obtained from medical records and reports of renal metabolic studies. Information was processed with the statistical software SPSS version 22.0. Average and standard deviation were estimated and use was made of frequency distribution analysis and homogeneity testing. Results: A predominance was found of female sex among patients with ADPKD (57.1 percent) and male sex among patients without ADPKD (63.4 percent). The most common disorders were hypercalciuria (45.3 percent) and hypophosphatemia (17.1 percent) in the non-polycystic population, and increased uric acid clearance (38.1 percent) and hypercalciuria (23.8 percent) in polycystic patients. Statistically significant differences were found in uric acid clearance increase (p = 0.01) and hyperphosphatemia (p = 0.04). Conclusions: The main metabolic disorders of lithiasis patients, polycystic as well as non-polycystic, are increased uric acid clearance, hypercalciuria, hyperuricosuria and hypophosphatemia, with a varying order of presentation. Increased uric acid clearance and hyperphosphatemia are more common in polycystic lithiasis patients(AU)

Resumen El objetivo del trabajo fue analizar los valores de hemoglobina glucosilada en el tercer trimestre de embarazo como predictores alternativos de la diabetes gestacional en pacientes del Noreste de México. Se trata de un estudio retrospectivo de casos y controles a partir de 121 expedientes de pacientes embarazadas, divididos en dos grupos, pacientes con diabetes gestacional (casos) y gestantes con valores glucémicos normales (controles). Se analizaron los factores de riesgo asociados a la diabetes gestacional y se obtuvo un punto de corte para la hemoglobina glucosilada. Se encontró que la obesidad materna, la edad y el antecedente del padecimiento fueron asociados significativamente con la diabetes gestacional. Valores de hemoglobina glucosilada ≥5% incrementaron el riesgo de padecer diabetes mellitus gestacional 4 veces y, aunado a un factor de riesgo, la probabilidad se incrementó 7 veces. Se concluye que los valores de hemoglobina glucosilada en el tercer trimestre de embarazo podrían emplearse como prueba diagnóstica de la diabetes gestacional en pacientes del Noreste de México. Sin embargo, aunque las diferencias encontradas fueron estadísticamente significativas, los resultados se deben interpretar con cautela y requieren su confirmación con estudios que incluyan una muestra mayor.
Abstract The objective of this study was to analise glycosylated hemoglobin values in the third trimester of pregnancy as an alternative predictor of gestational diabetes in North East Mexican cohort patients. This is a retrospective case-control study based on 121 records of pregnant patients, divided into two groups, patients with gestational diabetes (cases) and pregnant women with normal glycemic values (control). The risk factors associated with gestational diabetes were analised and a cut-off point for glycosylated hemogestaglobin was obtained. It was found that maternal obesity, age and a history of the condition were significantly associated with gestational diabetes. Values of glycosylated hemoglobin ≥5% increased the risk of suffering from gestational diabetes 4 times, and coupled with a risk factor, the risk increased 7 times. It is concluded that glycosylated hemoglobin values in the third trimester of pregnancy could be used as a diagnostic test for gestational diabetes in patients from the North East of Mexico. Although the differences found were statistically significant, our results must be interpreted with caution and require confirmation by studies with a larger sample.

Objective:To investigate the association of tumor necrosis factor-α(TNF-α)gene G308A single nucleotide polymorphism(SNP)with childhood obesity and metabolic disorders.Methods:A total of 620 obese children admitted to our pediatric department from January 2015 to December 2019 were selected as research subjects, who were divided into metabolic non-healthy group( n=267)and metabolic healthy group( n=353), and 260 healthy children were selected as the control group. Single nucleotide polymorphism of TNF-α gene G308A was detected, serum TNF-α level, obesity indicators, glucose and lipid metabolism indicators were compared among the children in various groups. Results:No significant differences in body mass index(BMI), waist circumference, hip circumference, and serum TNF-α level were found between metabolic non-healthy group and metabolic healthy group( P>0.05), but higher than those in control group( P<0.05). There were no significant differences in fasting plasma glucose(FPG)and total cholesterol(TC) levels among the three groups( P>0.05). The levels of fasting insulin(FINS), fasting glucagon(FGC), HbA 1C, triglyceride(TG), and low density lipoprotein-cholesterol(LDL-C)in metabolic non-health group and metabolic health group were significantly higher than those in control group, higher in metabolic non-health group compared with metabolic healthy group( P<0.05). HDL-C level in two obese groups was significantly lower than that in control group, lower in metabolic non-health group compared with metabolic healthy group( P<0.05). The frequencies of GG genotype and allele G in metabolic non-healthy group and metabolic healthy group were significantly lower than those in control group, lower in metabolic non-health group compared with metabolic healthy group. The frequencies of AA, GA genotypes and allele A were significantly higher in metabolic non-health group than those in metabolic healthy group( P<0.05). There were no significant differences in TNF-α, FPG, and TC among AA, GA and GG groups( P>0.05). BMI, waist circumference, hip circumference, FINS, FGC, HbA 1C, TG, HDL-C and LDL-C were comparable between AA type and GA type( P>0.05), but revealed a significant difference compared with GG type( P<0.05). Pearson correlation analysis showed that the level of TNF-α was positively correlated with BMI, waist circumference, hip circumference, FPG, FINS, FGC, HbA 1C, TC, TG, and LDL-C( P<0.05), but negatively correlated with HDL-C( P<0.05). Conclusion:TNF-α gene G308A single nucleotide polymorphism is associated with obesity and metabolic disorders in children.

Parkinson's disease (PD) is the second major neurodegenerative disease.The pathogenesis of PI) is still unclear.It is generally believed that neural damage, mitochondrial dysfunction, inflammation, oxidative stress and autophagy dysfunction caused by the transmission and aggregation of a- synuclein play an important role in the occurrence and development of PD.More and more research show- that metabolic disorder is one of the pathogenesis of PD.We examined whether overexpression of a- synuclein could induce metabolic disorder in mice and the possible mechanisms.Mice were divided into two groups: Thyl-aSYN transgenic mice (TG) and the control wild-type (WT) group.The rotarod test was used to analyze motor function in mice.We detected the body weight, plasma insulin content, glucose tolerance and insulin tolerance in the two group mice.The morphology of islets in the two groups were observed by hematoxylin eosin (HE) staining, and the islets were isolated to detect the glucose- stimulated insulin secretion (GSIS).The results showed that compared with the WT group, exercise tolerance of 12-month-old TG group decreased by 23.1% (P < 0.05) , body weight increased by 7% (P < 0.01), glucose tolerance decreased (P < 0.05), insulin tolerance decreased (P < 0.05), and insulin contents in the peripheral blood decreased by 20% (P < 0.05).Compared with the WT group, the levels of ce -syn proteins in the pancreas of the TG group increased by 1.32 times (P < 0.05) , the area of islets in the TG group decreased (P < 0.05 ) , the number of islets decreased (P < 0.01) , and the insulin secretion function decreased (P< 0.01).This study showed that the role of a-synuclein in PD is not limited to the damage of dopaminergic neurons, it also can affect metabolism and the morphology and function of peripheral organs, which provides a new theoretical basis for the pathogenesis of PD.

The aim of this study was to evaluate the effects and mechanisms of berberine (BBR) against dexamethasone (Dex)-induced metabolic disorders. 3T3-L1 cells were differentiated by Dex treatment and then treated with BBR (2.5, 5, 10 μmol·L-1). Lipid accumulation was detected using oil-red O staining. After review and approval of the ethics committee of the Institute of Materia Medica, Peking Union Medical College, Chinese Academy of Medical Sciences, C57BL/6N mice were randomly divided into three groups. In the BBR treatment group, mice were subcutaneously implanted with an osmotic pump containing Dex and gavaged with BBR (100 mg·kg-1·day-1) for 4 weeks. The model control group was implanted with a Dex osmotic pump with no other treatment. Mice given a saline-filled osmotic pump were used as a negative control. During the study, food intake and body weight were measured weekly. Subcutaneous fat and visceral fat was detected by MRI. At the end of the experiment the plasma levels of total cholesterol (CHO), triglyceride (TG), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), glucose (Glu), and muscle mass were measured. The expression of peroxisome proliferator-activated receptor γ (PPARγ) and AMP-activated protein kinase α (AMPKα) in 3T3-L1 cells and epididymal fat of C57BL/6N mice was evaluated through RT-PCR and Western blot analysis. The results showed that BBR inhibited Dex-induced adipocyte differentiation in 3T3-L1 preadipocytes by up to 23% in a dose-dependent manner. In C57BL/6N mice, berberine alleviated hyperlipidemia and hyperglycemia and reduced visceral fat accumulation induced by Dex. The results from RT-PCR and Western blot analysis showed that BBR reduced PPARγ expression and increased the phosphorylation of AMPKα in 3T3-L1 cells as well as in adipose tissue. Berberine might alleviate Dex-induced metabolic disorder and visceral fat accumulation by modulating PPARγ and AMPK expression.

As the most prevalent and abundant transcriptional modification in the eukaryotic genome, the continuous and dynamic regulation of N6-methyladenosine (m6A) has been shown to play a vital role in physiological and pathological processes of cardiovascular diseases (CVDs), such as ischemic heart failure (HF), myocardial hypertrophy, myocardial infarction (MI), and cardiomyogenesis. Regulation is achieved by modulating the expression of m6A enzymes and their downstream cardiac genes. In addition, this process has a major impact on different aspects of internal biological metabolism and several other external environmental effects associated with the development of CVDs. However, the exact molecular mechanism of m6A epigenetic regulation has not been fully elucidated. In this review, we outline recent advances and discuss potential therapeutic strategies for managing m6A in relation to several common CVD-related metabolic disorders and external environmental factors. Note that an appropriate understanding of the biological function of m6A in the cardiovascular system will pave the way towards exploring the mechanisms responsible for the development of other CVDs and their associated symptoms. Finally, it can provide new insights for the development of novel therapeutic agents for use in clinical practice.

OBJECTIVE@#To examine whether Caulerpa okamurae ethanolic extract (COE) could inhibit obesity-mediated inflammation, improve glucose metabolism and increase insulin sensitivity, using in vitro cell models of RAW 264.7 macrophages and 3T3-L1 adipocytes.@*METHODS@#We cocultured 3T3-L1 adipocytes in direct contact with lipopolysaccharide-stimulated RAW 264.7 macrophages and induced insulin resistance in 3T3-L1 adipocytes with tumor necrosis factor-α (TNF-α) in the presence or absence of 250 µg/mL of COE. We investigated various markers of inflammation, glucose regulation and insulin sensitivity in these models using Griess reagent to measure nitric oxide (NO) production, 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxyglucose to measure glucose uptake, Western blot analysis to quantify protein expression and reverse transcriptase-polymerase chain reaction to evaluate mRNA expression.@*RESULTS@#We found that COE (250 µg/mL) significantly inhibited the lipopolysaccharide-induced inflammatory response in RAW 264.7 macrophages by downregulating NO production, nitric oxide synthase 2 expression and nuclear translocation of nuclear factor-κB. COE also showed similar anti-inflammatory activity in coculture, along with decreased TNF-α, interleukin-6 and monocyte chemoattractant protein mRNA expression. In addition, COE also improved glucose uptake in coculture by upregulating glucose transporter-4 (GLUT-4) and adiponectin and reducing serine phosphorylation of insulin receptor substrate-1 (IRS1). In the TNF-α-induced insulin resistance model of 3T3-L1 adipocytes, COE significantly improved both basal and insulin-stimulated glucose uptake, accompanied by phosphorylation of IRS1 at tyrosine 632, phospho-5' adenosine monophosphate-activated protein kinase α and glycogen synthase kinase-3β (Ser9) as well as upregulation of GLUT-4.@*CONCLUSION@#Together, these findings suggest that COE has potential to treat or prevent obesity-induced metabolic disorders.

Metabolic syndrome (MS) is a group of syndromes caused by the disorder of metabolism of various substances in the body. The main clinical manifestations are dyslipidemia, central obesity, hypertension, abnormal glucose tolerance and insulin resistance. With the changes of diet structure and habits, the incidence rate of MS is increasing, and the patients are younger. It is an important factor in many diseases, such as diabetes, atherosclerosis, coronary heart disease, hyperlipidemia, cirrhosis and some cancers. MS has seriously affected people's lives and health. Central obesity and insulin resistance are recognized as important pathogenic factors. At present, the pathogenesis of MS and its components has not been fully understood. The clinical manifestations of metabolic syndrome are complex and diverse. Traditional Chinese medicine (TCM) believes that the occurrence of metabolic syndrome is related to such factors as proper diet, emotional disorders, excessive escape and little movement, old age and physical deficiency. TCM scholars have studied the pathogenesis of MS in such pathological factors as phlegm and blood stasis, such visceral functions as liver, spleen and kidney, roles of Qi and blood, and emotional factors. As the basic substance of organism, Qi is closely related to the process of metabolism. The occurrence of MS is closely related to the rise and fall of Qi moving to and from the body as well as the abnormal gasification function of the transformation of Qi. Qi is derived from the five internal organs, which are respectively called Heart Qi, liver Qi, spleen Qi, lung Qi and kidney Qi. The "Qi of the five internal organs" is involved in the whole process of the generation, transportation and excretion of the essence of the body. Based on the "Qi of five internal organs", this paper discusses the pathogenesis of MS with phlegm, blood stasis and water drink as pathological factors.

Polycystic ovary syndrome (PCOS) is a heterogeneous clinical entity that is defined as the association of hyperandrogenism with chronic an ovulation in women without specific underlying diseases of the adrenal or pituitary glands. PCOS is also associated with a metabolic disturbance with complex inter relation of obesity, insulin resistance and endocrine abnormalities remains unresolved. However, several studies link obesity, body fat distribution and nutritional habits with the hormonal and metabolic profiles of PCOS. Moreover, intervention studies have suggested that reducing weight and hyper insulinaemia either by diet alone or by a combination of diet with drugs improves hirsutism, fertility, hormonal and metabolic profiles of PCOS. In fact, the evaluation of nutritional factors in PCOS is helpful for the screening of metabolic abnormalities and the management of women with PCOS. A point of particular interest in the management of PCOS is that the choice of contraception remains difficult in these high cardiovascular risk women. The lack of prospective studies to evaluate long-term metabolic and cardiovascular tolerance necessitates care and the assessment of other hormonal possibilities
