ABSTRACT
Objective To investigate the level of serum uric acid in patients with diabetes insipidus (DI),summarize the clinical characteristics of central diabetes insipidus (CDI) patients with hyperuricemia (HUA),and analyze the factors affecting the level of serum uric acid in the patients with CDI. Methods The clinical data of DI patients admitted to Peking Union Medical College Hospital from 2018 to 2021 were retrospectively analyzed.The patients were assigned into a child and adolescent group (≤ 18 years old) and an adult group (>18 years old) according to their ages.The demographic and biochemical data between two groups of patients with and without HUA were compared.Spearman correlation analysis and multiple linear regression analysis were performed to analyze the correlations between serum uric acid level and other factors. Results Among the 420 DI patients,411 patients had CDI (97.9%),including 189 patients with HUA (46.0%).Thirteen (6.9%) out of the 189 CDI patients with HUA presented the disappearance of thirst.The prevalence of HUA in children and adolescents was higher than that in adults (χ2=4.193,P=0.041).The level of serum uric acid in the CDI patients with HUA and disappearance of thirst was higher than those without disappearance of thirst (U=2.593,P=0.010).The multiple linear regression predicted serum creatinine (β=0.472,95%CI=2.451-4.381,P<0.001) and body mass index (β=0.387,95%CI=6.18-12.874,P<0.001) as the independent risk factors of serum uric acid level increment in children and adolescents,while serum creatinine (β=0.361,95%CI=1.016-1.785,P<0.001),body mass index (β=0.208,95%CI=2.321-6.702,P<0.001),triglyceride (β=0.268,95%CI=12.936-28.840,P<0.001),and total cholesterol (β=0.129,95%CI=2.708-22.250,P=0.013) were the independent risk factors in adults. Conclusions The patients with CDI were more likely to have HUA,and the prevalence of HUA in children and adolescents was higher than that in adults.Body mass index,serum creatinine,triglyceride,total cholesterol,and disappearance of thirst were the risk factors for the increased level of serum uric acid in CDI patients.

To investigate the efficacy and value of optical genome mapping (OGM) in detecting chromosomal structural variations. In a clinical study about high-precision analysis of genomic structural variation for complex genetic diseases, a retrospective study was performed on the cases with karyotyping at the department of Obstetrics and Gynecology, and Endocrinology of Peking Union Medical College Hospital from January to December 2021. Ten cases with abnormal karyotype was detected by OGM. Partial cases were verified by fluorescence in situ hybridization (FISH), SNP array or CNV-seq. Results of ten cases, nine were detected with abnormality by OGM, including unbalanced chromosomal rearrangements (n=3), translocation (n=5) and paracentric inversion (n=1), and the results were in concordance with other standard assays. However, one case with breakpoint and reconnected at centromere has not been detected. In conclusion, ten samples were comprehensively analyzed by karyotyping, FISH, SNP array or CNV-seq, and OGM, and results demonstrated that optical genome mapping as a new technology can not only detect unbalanced rearrangements such as copy number variants as well as balanced translocations and inversions, but more importantly, it can refine breakpoints and orientation of duplicated segments or insertions. So it can contribute to the diagnosis of genetic diseases and prevent birth defect. However, the current technology is not yet capable of detecting breakpoints of balanced structural variations lying within unmapped regions.

Objective To investigate the effects of metformin on insulin sensitivity and secretion in patients with obesity and insulin resistance. Methods This study enrolled 42 obesity patients with insulin resistance who were regularly followed-up in Peking Union Medical College Hospital from September 2012 to May 2016. They were divided into two groups according to their different status of glucose metabolism: normal glucose tolerance( NGT) and impaired glucose regulation( IGR) . Life style intervention and metformin were given to all these patients. The antropometric and metabolic data were collected before treatment, 3 and 6 months after treatment respectively. Results 42 patients, aged (23.6±6.5) years, including 11 males and 31 females were enrolled. 19 of them were NGT and 23 were IGR (8 of IGT and 15 of IFG) . Among all these patients, fasting insulin was significantly higher at 3 months after treatment(P＜0.05).The same results were shown in group-NGT(P＜0.05). Fasting insulin was significantly lower at 6 months after treatment than at baseline among all patients( P＜0.05) . HOMA-IR showed no significant difference between the baseline and 3 months after treatment, but significantly higher at baseline and 3 months after treatment than 6 months after therapy( P＜0.001) . HOMA-beta was significantly( P＜0.001) lower be-fore treatment and 6 months treatment the effect was more significant than 3 months after treatment among all pa-tients. HOMA-beta was significantly lower at baseline in group-IGR than at baseline in group-NGT ( P＜0.05) . Conclusions The effect of metformin on insulin secretion is earlier than that of improving the insulin sensitivity in patients with obesity and insulin resistance. Metformin is more likely to promote insulin secretion in patients with normal glucose tolerance than those with IGR within 3 months of intervention.

Objective To analyze the effectiveness and safety of laparoscopic sleeve gastrectomy (LSG) in treating obesity and its co-morbidities.Methods The clinical data of obese patients undergoing LSG in Peking Union Medical College Hospital from August 2012 to August 2017 were retrospectively analyzed. Medium-term outcome measures included excess weight loss (%EWL),co-morbidity improvement,and complications.Results Seventy-five obese patients comprising 28 men[ body mass index(BMI):(47.3±7.5)kg/m ) ] and 47 women [BMI (41.1±7.0) kg/m ] were enrolled in this analysis. The common co-morbidities were liver dysfunction (53.3%),dyslipidemia (52.0%),obstructive sleep apnea (45.3%),type 2 diabetes mellitus (38.7%),and arterial hypertension (37.3%),which were improved by 75.0%,58.3%,83.3%,75.0% and 58.3% three years after surgery. The mean %EWL at 1,2,and 3 years after surgery was 81.6±34.7,80.9±30.2 and 79.7±30.8,respectively. The proportions of patients achieving successful weight loss were 81.7% (n=49),81.0% (n=34),and 79.3% (n=23) at 1,2,and 3 years (%EWL>50%). Early severe complications (Clavien-Dindo classification>2) occurred in 2.6% of patients,and the most common late complications was gastroesophageal reflux disease,which could be relieved by acid suppressants.Conclusion LSG is effective and safe in treating obesity and its co-morbidities.
ABSTRACT
Objective To evaluate the prevalence and clinical characteristics of obstructive sleep apnea (OSA) in bariatric surgery population.Methods Consecutive patients undergoing preoperative evaluation for bariatric surgery and referred for sleep monitoring in Peking Union Medical College Hospital from January 2009 to December 2015 were retrospectively analyzed. Age,gender,symptoms of snoring,fatigue,apnea and somnolence,apnea hyponea index (AHI),arterial blood gas,pulmonary function,sleep respiratory monitoring,positive airway therapy of OSA,and postoperative complications were recorded. The clinical characteristics of OSA groups at different severity were compared using AHI≥5 events/hour and AHI≥15 events/hour as cut-off values. Correlation analysis was applied to identify the clinical factors associated with AHI.Results Of 42 patients with complete sleeping monitoring data before bariatric surgery,30(71.4%) were diagnosed as OSA,14 (33.3%) were moderate or severe and 11 (26.2%) were severe. Also,OSA was not detected before the bariatric surgery in 25 cases (83.3%). Compared with patients with AHI<5 events/hour,patients with AHI≥5 events/hour had significantly older age (t=2.869,P=0.007),higher proportion of observed apnea (P=0.035),higher AHI (z=-4.592,P=0.000),higher proportion of night pulse oxygen saturation(SpO) below 90% (z=-2.746,P=0.006),lower mean SpO (t=-2.071,P=0.046) and lower lowest SpO (t=-3.914,P=0.000). Compared with AHI<15 events/hour group,the AHI≥15 events/hour group had significantly higher BMI (t=2.281,P=0.043),male ratio (P=0.005),incidence of hypertension (P=0.011),proportion of observed apnea (P=0.001),percentage of smoking history (P=0.017),partial pressure of carbon dioxide(PaCO)(t=3.478,P=0.002),AHI (z=-4.592,P=0.000),and proportion of night SpO below 90% (z=-4.530,P=0.000); in addition,the forced expiratory volume in one second(FEV1)% predicted (t=-3.377,P=0.002),forced vital capacity(FVC)% predicted (t=-2.342,P=0.026),night time mean SpO (t=-3.392,P=0.007),lowest SpO (t=-5.535,P=0.000) were significantly decreased. Correlation analysis showed that,in populations with normal PaCO (n=36),AHI was positively correlated with age (r=0.450,P=0.006) and BMI (r=0.384,P=0.021) and negatively correlated with FEV1% predicted (r=-0.457,P=0.008) and FVC% predicted (r=-0.432,P=0.013). Partial correlation analysis showed that,after age and BMI were adjusted,AHI was not correlated with FEV1% predicted(r=-0.287,P=0.125)and FVC%predicted(r=-0.241,P=0.200).Conclusion The incidence and underdiagnosis rate of OSA are high in bariatric surgery population. OSA should be routinely screened in bariatric population to reduce the postoperative complication.
ABSTRACT
Traumatic brain injury(TBI)is a major cause of hypothalamopituitary dysfunction. TBI-related hypothalamopituitary dysfunction is more common in the acute phase. Disturbance of pituitary/gonadal axis and growth hormone axis,as well as posterior pituitary dysfunction including central diabetes insipidus and syndrome of inappropriate antidiuretic hormone secretion,are the most frequently seen. During the chronic phase of TBI,anterior hypopituitarism is the major concern,which affects the quality of life. Risk factors for hypothalamopituitary dysfunction following TBI include low Glasgow score,high body mass index,hypoxia,older age,longer intensive care unit stay and longer coma status,radiological evidence of acute brain injury,and increased intracranial pressure. Children and adolescents are in a crucial period of growth and development,and therefore TBI-related pituitary dysfunction during this period can substantially affect the cognition and behaviors. There is currently no reliable biochemical marker predicting hypothalamopituitary dysfunctions. Therefore,it is of great importance to evaluate the pituitary function and take appropriate hormone replacement for moderate-severe TBI patients or mild TBI patients with apparent symptoms,especially for patients with water-electrolyte disturbance and adrenal deficiency. Growth hormone and gonadal hormone replacement therapies are crucial for children and adolescents.
ABSTRACT
<strong>Objective</strong> To evaluate physicians' attitude and knowledge about the management of adult growth hormone deficiency (AGHD) at Peking Union Medical College Hospital and impact factors associated with better decision-making.<strong>Methods</strong> A 21-question anonymous survey was distributed and collected at Peking Union Medical College Hospital, a major teaching hospital in Chinese Academy of Medical Sciences. Data of physicians' educational background, clinical training, patient workload per year and continuing medical education in AGHD were collected. Factors associated with appropriate answers were further analyzed by multivariate regression models.<strong>Results</strong> One hundred and eighteen internal medicine residents, endocrine fellows, attending physicians and visiting physicians responded to the survey. Among them, 44.9% thought that AGHD patients should accept recombinant human growth hormone replacement therapy. Moreover, 56.8% selected insulin tolerance test and growth hormone-releasing hormone-arginine test for the diagnosis of AGHD. Logistic regression analysis of physician demographic data, educational background, and work experience found no consistent independent factors associated with better decision-making, other than continued medical education, that were associated with treatment choice.<strong>Conclusions</strong> The physicians' reported management of AGHD in this major academic healthcare center in Beijing was inconsistent with current evidence. High quality continued medical education is required to improve Chinese physician management of AGHD.

ABSTRACT
Cushing's disease (CD) is a relatively rare disease,characterized by pathological hypercortisolism secondary to excessive adrenocorticotrophic hormone that is secreted by pituitary adrenocorticotrophic hormone adenoma or hyperplasia. In addition to the typical clinical symptoms such as moon face,buffalo hump,and central obesity,the CD patients may also experience mental disorders and cognitive dysfunction. This review mainly focuses on the cognitive state of CD patients,the mechanisms of cognitive impairment caused by high cortisol levels,and the imaging findings (especially magnetic resonance imaging) for the evaluation of cognitive functions.

Because of limited viral replication and lack of cytopathic effect in cell culture, a new PCR-based rapid seroneutralization assay for detection of GII.4 norovirus neutralized antibodies was developed with serum samples from acute-phase patients, convalescent-phase patients and healthy controls. According to this study, neutralizing antibodies were detected in 100% of convalescent-phase sera, and in 2.5% of healthy controls sera. However, all of the acute-phase serum samples could not neutralize virus efficiently. Compared to the results from ELISA (96.2% at sensitivity and 80% at specificity), the present in vitro neutralization assay is more specific and more sensitive.

<p><b>OBJECTIVE</b>To explore the clinical and magnetic resonance imaging (MRI) findings of pituitary hyperplasia due to primary hypothyroidism.</p><p><b>METHOD</b>The clinical presentations, laboratory examinations, and MRI findings of 11 patients with pituitary hyperplasia secondary to primary hypothyroidism diagnosed at our hospitals from the beginning of 2008 to the end of 2011 were retrospectively reviewed.</p><p><b>RESULTS</b>The clinical manifestations in 11 patients included growth arrest(7/8), mental retardation (6/8), cold intolerance and fatigue(6/11), slightly increased body weight (6/11), galactorrhea (3/11), paramenia (8/9), precocious puberty companying vaginal bleeding (2/2),and blurry vision (3/11). Laboratory investigations revealed grossly increased thyroid stimulating hormone, decreased thyroxine, and slightly elevated prolactin levels in all cases. Thyroid antibody was positive in six cases. On MRI, pituitary mass were detected a large intrasellar with/without suprasellar extension in all patients,showing the characteristic of symmetric enlargement. Spherical shape was viewed in 5 cases,with the height of (12.22 ± 3.12)mm. In the other 6 cases, the pituitary mass with the shape of calabash extended superiorly to suprasellar area, with a height of(18.95 ± 2.23)mm. The signal of pituitary mass was isointense to grey matter both on T1 weighted imaging and T2 weighted imaging. Bright short T1 signal in posterior lobe of pituitary was visible. Pituitary stalk was detected only in 4 cases from MRI without dislocation, while the width of pituitary stalk was within the normal limit.</p><p><b>CONCLUSIONS</b>Pituitary hyperplasia should be considered when homogenous enlargement of the pituitary gland is found on MRI. The integration of MRI findings, clinical manifestations, and laboratory findings is helpful for the proper identification of the primary endocrine disease and thus avoid misdiagnosis.</p>

<p><b>BACKGROUND</b>Generalized glucocorticoid resistance syndrome is a rare familial or sporadic condition characterized by generalized, partial, target-tissue insensitivity to glucocorticoids. This syndrome is partially caused by mutations in the human glucocorticoid receptor (hGR) gene. The clinical spectrum of generalized glucocorticoid resistance is broad, ranging from fatigue or no symptoms to severe hypertension with hypokalemic alkalosis. The purpose of this study was to explore the genetic disorder of glucocorticoid resistance syndrome.</p><p><b>METHODS</b>We identified a 56-year-old male patient diagnosed with generalized glucocorticoid resistance syndrome accompanied with an adrenocortical adenoma. This asymptomatic patient referred to Peking Union Medical College Hospital for treatment of his adrenal incidentaloma. Endocrinological evaluation consistently revealed his elevated serum cortisol level. Total RNA was extracted from the patient's peripheral blood mononuclear leukocytes (PBMLs) and entire coding region of hGR alpha was amplified by reverse transcription (RT)-PCR. To confirm the possible mutation identified by sequencing RT-PCR products, genomic DNA sequence of hGR gene from the patient and 50 healthy controls was analyzed by PCR and directly sequencing.</p><p><b>RESULTS</b>A heterozygotic (C→T) substitution at nucleotide position of 1667 (exon 5) in GR alpha gene was found in this patient by sequencing of RT-PCR products of hGR gene. This substitution was also identified at genomic DNA level and it was absent in 100 chromosomes from 50 unrelated health controls. This substitution resulted in a threonine to isoleucine substitution (ACT→ATT) at amino acid 556 in the ligand-binding domain of GR alpha.</p><p><b>CONCLUSION</b>Generalized glucocorticoid resistance in this patient might be caused by a novel heterozygotic mutation in the ligand-binding domain of the GR alpha.</p>

The number of new cases of hypophyseal tumor increases along with the advances in neuroimaging technology in recent years. The common treatment models include surgical treatment, radiotherapy, and medical therapies. This article discusses the application of long-term follow-up in non-operative hypophyseal tumor patients and its influence on the prognosis. Meanwhile, since the medical mode has switched from biomedical model to biopsychosocial medical model, management of hypophyseal tumor should not be limited in its biological aspect, but also from the perspective of psychology by providing more humanistic care to meet the patients'psychological needs.

Obesity has become a major health problem worldwide. The prevalence and morbidity of obesity-related diseases including diabetes, hypertension, cerebro-cardiovascular diseases, and tumors also have remarkably increased. Treatment of obesity poses a challenge for clinicians. Anti-obesity treatment is helpful to improve and even reverse obesity-related complications. Diet control and physical exercises remain the predominant interventions for obese patients. Anti-obesity drugs can be considered in those who respond poorly to behavioral intervention or those who have developed obesity-related complications. The commonly used anti-obesity drugs include gastrointestinal lipase inhibitors and appetite suppressants. Glucagon-like peptide 1 has also been found to be effective in reducing body weight. Some more drugs are under development, which include selective 5-HT 2c agonist, β3 receptor agonist, and melanocortin receptor 4 agonist, may also be promising.
