RESUMEN
Objective: To analyze the correlation between fatty liver index (FLI) and myocardial remodeling. Methods: For cross-sectional study, cluster sampling was used to conduct a follow-up study of "Risk evaluation of cancers in Chinese diabetic individuals: A longitudinal (REACTION) study" among communities of Gucheng and Pingguoyuan of Beijing from April 2015 to September 2015. According to the inclusion and exclusion criteria, 8 848 participants were selected. Biochemical indicators such as body mass index, waist circumference, triglycerides, and γ-glutamyl transpeptidase were detected to calculate the FLI. The correlation between FLI and myocardial remodeling was analyzed. Interventricular septal thickness (IVS), left atrial diameter (LAD), left ventricular end diastolic diameter (LVEDD), and the presence of diastolic dysfunction were measured by color doppler ultrasound. The participants were divided into Q1 group (FLI<30, 4 529 cases), Q2 group (30≤FLI<60, 2 762 cases), and Q3 group (FLI≥60, 1 557 cases) based on FLI levels. Single factor analysis of variance was used for inter-group comparison, logistic regression analysis was used to analyze the correlation between FLI and myocardial remodeling. Results: A total of 8 848 subjects were selected for the study (3 110 male and 5 738 female, mean age: 59.96 years). The IVS of Q1, Q2, and Q3 groups were (9.35±1.08), (9.73±1.22), and (10.07±1.31) mm, respectively. The LAD were (30.94±3.90), (33.37±4.12), and (34.98±4.47) mm, respectively. The LVEDD were (42.51±5.05), (44.43±5.10), and (46.06±5.52) mm, respectively. All increased with the increase of FLI (all P<0.001). FLI was an independent risk factor for IVS thickening, LAD increase, LVEDD increase, and diastolic function decrease. The respective risks for IVS thickening, LAD increase, LVEDD increase, and diastolic function decrease in a population with intermediate and higher FLI levels was 1.62 times (95%CI 1.39-1.89) and 2.53 times (95%CI 2.13-3.00); 2.71 times (95%CI 2.39-3.06) and 5.00 times (95%CI 4.12-6.08); 2.36 times (95%CI 1.85-3.00) and 4.33 times (95%CI 3.33-5.62); and 1.90 times (95%CI 1.63-2.19) and 1.95 times (95%CI 1.60-2.37) than those with lower FLI levels. Conclusion: There is a certain relevance between FLI and myocardial remodeling.

Both periodontitis and diabetes are chronic inflammatory diseases, which are widely prevalent in the world. For more than 50 years, the research on the relationship between periodontitis and type 2 diabetes has been actively carried out. The epidemiological correlation between these diseases has been basically identified, but the impact of periodontal therapy on glycaemic control in patients with type 2 diabetes has been controversial for a long time. Glycaemic control is a key issue in the care of people with diabetes. If the positive effect of periodontal therapy on improving glycemic control in diabetic patients compared with no active treatment can be identified, it will help establish periodontal therapy as an effective auxiliary measure for glycaemic control of diabetes patients, and further confirm the relationship between dental health and systemic diseases. Through reviewing the literature, it has been basically determined that the glycaemic control of diabetes patients can be improved within 6 months after the commencement of non-surgical periodontal therapy. In addition, the guidelines of diabetes and suggestions involved periodontal therapy that are constantly put forward by various countries and health organizations at all levels,while in China with extremely heavy in the burden of diabetes, also should propose the guidelines and suggestions of diabetes in accordance with China's national conditions. Both periodontitis and diabetes are diseases with special emphasis on prevention. To clarify the relationship between periodontitis and diabetes can give enlightenment in preventing the occurrence and development of the two diseases.

Objective: To investigate the association between reproductive lifespan duration (RLD) and urinary albumin-creatinine ratio (UACR) in a Chinese postmenopausal population. Methods: This cross-sectional study included 11 055 naturally postmenopausal women from seven regions of China from May to December 2011. RLD was divided into four groups. Propensity score matching was performed to reduce bias, and logistic regressions and stratifications were conducted to investigate the association between RLD and increased UACR (≥30 mg/g). Mediation effect analysis was performed to quantify the effect of RLD on cardiovascular disease (CVD) induced by elevated UACR. Results: There were 2 373 participants with a RLD of 18-31 years, 2 888 participants with a RLD of 32-34 years, 2 472 participants with a RLD of 35-36 years, and 3 322 participants with a RLD of 37-50 years. The shortest RLD (18-31 years) group was characterized with older age (P<0.001), a higher incidence of CVD (P=0.025), and the highest level of UACR (P<0.001). After adjusting for confounders, women with a longer RLD (37-50 years group) exhibited a lower risk of UACR elevation compared with those with the shortest RLD (18-31 years group) (OR=0.72, 95%CI 0.64-0.82, P<0.001). Every 1-year extension in RLD was linked to a 2% reduction in the risk of UACR elevation (OR=0.98, 95%CI 0.97-0.99, P<0.001). Stratified analysis revealed a more significant association between RLD and UACR in women who were a normal weight (P=0.003) or overweight (P=0.001), in those without CVD history (P=0.001), and in those with impaired estimated glomerular filtration rate (P=0.004). The mediation casual analysis showed that 3.0% of proteinuria inducing CVD events was mediated by RLD (P=0.048). Conclusion: A longer RLD (37-50 years) is associated with a lower UACR in Chinese postmenopausal women.

Objective: Development and validation of a nomogram for predicting the 4-year incidence of type-2 diabetes mellitus (T2DM) in a Chinese population was attempted. Methods: This prospective cohort study was conducted in Shijingshan District Pingguoyuan Community (Beijing, China) from December 2011 to April 2012 among adults aged≥40 years not suffering from T2DM. Finally, 8 058 adults free of T2DM were included with a median duration of follow-up of 4 years. Participants were divided into a modeling group and verification group using simple random sampling at a ratio of 7â¶3. Univariate and multivariate Cox proportional risk models were applied to identify the independent risk predictors in the modeling group. A nomogram was constructed to predict the 4-year incidence of T2DM based on the results of multivariate analysis. The Concordance Index and calibration plots were used to evaluate the differentiation and calibration of the nomogram in both groups. Results: A total of 5 641 individuals were in the modeling group and 2 417 people were in the validation group, of which 265 and 106 had T2DM, respectively, at 4-year follow-up. In the modeling group, age (HR=1.349, 95%CI 1.011-1.800), body mass index (HR=1.347, 95%CI 1.038-1.746), hyperlipidemia (HR=1.504, 95%CI 1.133-1.996), fasting blood glucose (HR=4.189, 95%CI 3.010-5.830), 2-h blood glucose level according to the oral glucose tolerance test (HR=3.005, 95%CI 2.129-4.241), level of glycosylated hemoglobin (HR=3.162, 95%CI 2.283-4.380), and level of γ-glutamyl transferase (HR=1.920, 95%CI 1.385-2.661) were independent risk factors for T2DM. Validation of the nomogram revealed the Concordance Index of the modeling group and validation group to be 0.906 (95%CI 0.888-0.925) and 0.844 (95%CI 0.796-0.892), respectively. Calibration plots showed good calibration in both groups. Conclusion: These data suggest that our nomogram could be a simple and reliable tool for predicting the 4-year risk of developing T2DM in a high-risk Chinese population.

Objective: To explore the characteristics of the association between the triglyceride glucose (TyG) index and nonfatal cardio-cerebrovascular disease risk in a community population. Method: This was a prospective cohort study. From December 2011 to April 2012, the first investigation was conducted among subjects with more than 40-year old who were from Shijingshan district and Pingguoyuan community in Beijing. The second investigation was conducted from April to October 2015. All the subjects were divided into three groups according to the tertile of the TyG index at baseline. The multivariate Cox proportional risk regression model was established to explore the correlation between the TyG index and nonfatal cardio-cerebrovascular disease risk and the Kaplan-Meier survival curve of the TyG index group was drawn. Subgroup analyses were performed according to age, gender, body mass index, type 2 diabetes mellitus (T2DM), hypertension, and hyperlipidemia to determine the correlation characteristics between the TyG index and nonfatal cardio-cerebrovascular disease among subgroups. Results: A total of 9 577 subjects were finally included to analyze. The mean follow-up time of this study was (34.14±3.84) months. During the follow-up, 363 subjects (3.8%) occurred nonfatal cardio-cerebrovascular disease. The multivariate Cox regression analysis results showed that the hazard ratio (HR) of nonfatal cardio-cerebrovascular disease in the high TyG index group was 1.54 (95%CI 1.19-1.98), 1.60 (95%CI 1.23-2.10), and 1.57 (95%CI 1.20-2.05) in the three models, compared with the low TyG index group. The Kaplan-Meier analysis showed that the risk of nonfatal cardio-cerebrovascular disease increased from the low-TyG index group to the high-TyG index group (P=0.015). In the six subgroups analysis, only gender was shown to have a significant interaction effect with the TyG index and nonfatal cardio-cerebrovascular disease risk. In the female population, the risk of nonfatal cardio-cerebrovascular disease is significantly increased with the increase in the TyG index level (P<0.001). Conclusions: A high TyG index is independently related to the increased risk of nonfatal cardio-cerebrovascular disease in the Beijing community population. Gender has a significant interaction with the TyG index and nonfatal cardio-cerebrovascular disease risk. Therefore, the TyG index may be a useful marker to predict the nonfatal cardio-cerebrovascular disease risk of a community population.

Objective: To summarize the correlation between anterior pituitary function and tumor size in patients with different hormone-secreting pituitary adenomas. Methods: This was a retrospective case series study. The clinical data of 1 946 patients with pituitary adenoma hospitalized in the First Medical Center of Chinese PLA General Hospital from January 1, 2005, to December 31, 2020, were collected. The correlation between tumor size and anterior pituitary hormone levels was analyzed using Spearman rank correlation analysis in different types of pituitary adenomas. Results: The median age of the 1 946 patients was 45.1 years, of which 857 (44.0%) were men. The maximum tumor diameter of the patients [M (Q1, Q3)] was 22 (14, 30) mm. Tumor size in nonfunctioning adenomas (n=1 191) was negatively correlated with adrenocorticotropic hormone (ACTH) (r=-0.11, P<0.001), growth hormone (r=-0.13, P<0.001), and luteinizing hormone (men: r=-0.26, P<0.001, women: r=-0.31, all P<0.001). The tumor size of somatotropic adenomas (n=297) was positively correlated with growth hormone (r=0.46, P<0.001), but negatively correlated with male testosterone (r=-0.41, P<0.001). The tumor size of ACTH-secreting pituitary adenomas (n=155) was positively correlated with the ACTH level at 8â¶00 AM (r=0.25, P<0.001); however, no correlation was found with cortisol at 8â¶00 AM (P>0.05). The tumor size of prolactinomas (n=303) was positively correlated with the prolactin level (men: r=0.34, P=0.001; women: r=0.13, P=0.070). Conclusions: The correlation between the function of the anterior pituitary and size of the tumor depends on the cellular origin of the pituitary adenoma and specific type of hormone secretion. In somatotroph adenomas, ACTH-secreting pituitary adenomas, and prolactinomas, there is a positive correlation between tumor size and level of hormones secreted by the corresponding tumors. In patients with nonfunctioning adenomas, the tumor size was negatively correlated with the hormone levels of the pituitary-adrenal and pituitary-growth hormone axes.

Objective: To provide insight into the diagnosis for clinicians, the clinical characteristics, diagnosis and treatment history of 3 patients with 21-hydroxylase deficiency (21-OHD) and testicular adrenal rest tumors (TART) were analyzed. Methods: The clinical, laboratory and imaging data of 3 male patients with 21-OHD and TART, confirmed with CYP21 gene sequencing, from May 2010 to May 2021 in the First Medical Center of Chinese PLA General Hospital were analyzed retrospectively. The treatment strategy and clinical outcome were followed up. Results: All the 3 patients were first diagnosed with bilateral adrenal mass at the age of 27-42 years old. They were 145-162 cm tall. The levels of progesterone, 17-hydroxyprogesterone, and adrenocorticotropic hormone (ACTH) of the 3 patients were relatively high, and that of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) of the 3 patients were low. Testosterone level of 1 patient was significantly elevated, and that of the other 2 patients was below the lower limit of normal range. Testicular ultrasound showed heterogeneous hyperechoic masses in both testes. CT of the adrenal glands showed bilateral adrenal enlargement with mass. All 3 patients were treated with dexamethasone. After 4-96 months of follow-up, 17-hydroxyprogesterone level was kept above the median normal level. One of the patients got married and had a baby after treatment. The sizes of adrenal hyperplasia and testicular masses reduced to various degrees with the change of the testicular masses being proportional to that of adrenal hyperplasia. Conclusions: Patients with 21-OHD are prone to have TART, leading to the impaired testicular function. Early glucocorticold therapy is beneficial to the reduction of TART and restoration of testicular function.

Diabetes is the most important comorbidity of cardiovascular disease, and cardiovascular disease is the main cause of mortality and disability of patients with type 2 diabetes. In order to standardize the diagnosis and treatment of patients with diabetes and cardiovascular disease, the National Health Commission Capacity Building and Continuing Education Center organized the experts from the field of cardiology and endocrinology systematically reviewing the research progresses and expert experiences of relevant disciplines from home and abroad, and formulated this consensus. This consensus covers the diagnosis, drug treatment, and risk factor management for patients with diabetes and cardiovascular disease (including atherosclerotic cardiovascular disease and heart failure) from the perspective of cardiovascular disease and diabetes management aiming to strengthen the comprehensive management of patients and ultimately to improve the prognosis of patients. The management of cardiovascular diseases mainly includes the management of blood pressure, blood lipids, anti-thrombosis, anti-myocardial ischemia, anti-ventricular remodeling and so on. Diabetes management mainly includes lifestyle intervention (including diet, exercise, weight loss, etc.), anti-hyperglycemia therapy (including drugs and insulin), blood glucose monitoring, and hypoglycemic prevention. In addition, specific clinical recommendations are given to patients with special health care needs such as diabetic nephropathy, elderly (>75 years), and cardiovascular critical illness.

Objective: To compare the differences of brain functional damage of subtypes of patients with Cushing's syndrome (CS). Methods: A total of 11 adrenocorticotropic hormone (ACTH)-dependent CS patients and 29 ACTH-independent CS patients were recruited from Chinese PLA General Hospital between September 2015 and March 2017 with confirmed CS. The psychiatric scales and brain task functional magnetic resonance imaging (fMRI) were evaluated. Results: A total of 40 patients (34 females, 6 males) with a mean age of (39.20±12.10) years and a median education level of 12 (9, 16) years were enrolled. ACTH-dependent patients had significantly worse performance than the ACTH-independent patients in response to the depression evaluation (64.6±6.1 vs 56.2±12.8, P=0.008), positive emotion (17.8±4.2 vs 24.3±7.2, P=0.008) and CS life quality [31(29,33) vs 42(29,51), P=0.040]. In the reaction to positive target pictures, ACTH-dependent CS patients showed stronger activation in left superior temporal gyrus compared with patients in ACTH-independent group, while the activation degree of their bilateral dorsal anterior cingulate cortex, bilateralsuperior frontal gyrus and left middle frontal gyrus was much worse. In the reactions to negative target pictures, ACTH-dependent CS patients had weaker activation in bilateral cerebellum, left superior frontal gyrus, left middle frontal gyrus, left precuneus and right postcentral gyrus, compared with patients in the ACTH-independent CS group (P<0.01, AlphaSim corrected). The activation degree of some regions whose brain function was different between the two groups was correlated to the cortisol level, ACTH level, 24 h urinary free cortisol (UFC) level, depression evaluation and negative emotion assessment (all P<0.05). Conclusions: The severity of the depression and the life quality of patients in ACTH-dependent group are worse than ACTH-independent CS patients. The brain function of ACTH-dependent CS patients is much weaker.

BACKGROUND: Caloric restriction (CR) increases both average and maximum lifespan, retards physiological signs of ageing, and delays the onset of several diseases and may mediate neuropathic pain. Neuropathic pain seriously affects the quality of life of patients. In this study, we investigated whether CR exerts anti-nociceptive effects on neuropathic pain, and probed its potential mechanisms. METHODS: Adult rats were divided into two dietary groups: an ad libitum (AL)-fed group and a CR group, which was provided with 60% of the food intake of AL rats for 6 weeks. The effects of 6-week CR on pain behaviour and neuro-inflammation induced by chronic constriction injury of the sciatic nerve were evaluated. RESULTS: Rats subjected to a CR diet had reduced hypersensitivity to mechanical and thermal stimuli after nerve-constriction injury. CR increased the silent information regulator 1 (SIRT1) expression, and suppressed the nerve-constriction-induced production of mitochondrial-derived reactive oxygen species and activation of nuclear factor kappa B accompanied by suppression of mature interleukin-1ß production in the ipsilateral spinal cord dorsal horn. The inhibition of SIRT1 reversed the effects of caloric restriction on pain behaviours. Moreover, CR decreased the phosphorylation of N-methyl-d-aspartate receptor subunits and the mitogen-activated protein kinase family, decreased the sensory neurone excitability, and inhibited the nerve-constriction-induced glial-cell activation. CONCLUSIONS: These results suggest that the effects of CR on pain behaviours in a rat model of nerve injury are via inhibition of excessive neuro-inflammation induced by the injury. CR may be of benefit in patients with neuropathic pain.

Objective: To evaluate the clinical characteristics and etiologies of central diabetes insipidus (CDI). Methods: The clinical data of 230 patients with CDI in the Department of Endocrinology of Chinese PLA General Hospital from 2008 June to 2014 December were collected and analyzed retrospectively. Results: The three most common causes of CDI were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. Among all the CDI, the idiopathic CDI accounted for 37.48%. There were significant differences in age onset and gender distribution among the different causes of CDI. The patients with intracranial germ cell tumors [age of onset(19.2±10.2) years] were younger than the other types of CDI. Germ cell tumors patients were more common in male, and lymphocytic hypophysitis patients were more common in female. The most frequent abnormality of anterior pituitary in patients with CDI was growth hormone deficiency, followed by hypogonadism, adrenal insufficiency and hypothyroidism. The dysfunction of thyroid axis and adrenal axis in patients with germ cell tumor was more common than those in patients with idiopathic and lymphocytic hypophysitis. Conclusions: The most common causes of central diabetes insipidus were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. There were differences in age of onset, gender distribution and abnormal production of anterior pituitary hormones among all causes of CDI patients.

Objective: To analyze clinical features, prognosis and treatment of lymphocytic hypophysitis (LYH). Methods: The clinical data, treatments and outcomes of 18 cases diagnosed as LYH at Chinese PLA General Hospital between January 2001 and July 2017 was respectively reviewed. Results: Eighteen patients with histology-proven LYH (13 females and 5 males ) were identified. All lymphocytic adenohypophysitis (LAH) were females(n=6), two of whom were associated with pregnancy. Eleven patients (6 females and 5 males) had lymphocytic panhypophysitis (LPH) and one(female) had hypothalamitis. Pre-treatment evaluation revealed that 11 patients presented with symptoms of intracranial space-occupying lesions, 12 patients had symptoms of anterior pituitary hormone deficiencies, and 12 patients had central diabetes insipidus (CDI). All patients had space-occupying lesions on magnetic resonance imaging (MRI), which were symmetrically enlarged and homogenously enhanced with or without pituitary stalk thickening. Before or after surgery, 11 patients received immunosuppressant therapy or radiotherapy to alleviate space-occupying effect. After 4-204 months follow-up, 5 patients had a relapse and received immunosuppressants, radiotherapy or surgery to achieve remission. Full recovery (both symptomatic and radiographic) was seen in 6 patients, and 11 patients maintained stable replacement therapy. Conclusions: LYH presents with acute space-occupying effects such as headache, visual disturbances, hypopituitarism, CDI and mild hyperprolactinemia, especially with characteristic radiographic manifestations. Usually, surgery reliably establishes diagnosis, and immunosuppressant therapy is a necessity. On the whole, LYH has a good prognosis.

Objective: To summarize and analyze the clinical features and etiologies in hospitalized patients with syndrome of inappropriate antidiuretics (SIAD) during the past 25 years. Methods: All data of 128 patients with SIAD admitted to Chinese PLA General Hospital since January 1991 to January 2016 were collected. SIAD was diagnosed based on the 1957 criterion. Results: (1) The most frequent causes of increased inappropriate secretion of vasopressin were malignant tumors, lung diseases (e. g. pneumonia), and central nervous system diseases, in which malignant tumors accounted for 38.28% of the SIAD. (2) During the past 25 years, the proportion of malignant diseases declined from 4/7 to 35.29%, while, the proportion of pulmonary infection increased from 1/7 to 35.29% (P<0.05). (3) The patients with malignant tumors had the lowest serum sodium and serum osmolality among all SIAD patients. (4) CT scan had a high diagnostic value for chest and brain detection. (5) Among three SIAD subjects with unknown reasons at onset, two were diagnosed with small cell lung cancer and one with gastric cancer during follow-up. Conclusion: The etiology of SIAD is complex and it could be attributed to multifarious etiological factors. Malignant tumors account for the largest proportion of all patients, and pulmonary infection was ranked in second place. Cautions on tumors have to be taken when serum sodium of a SIAD patient is below 118.1 mmol/L.

Objective: To evaluate the efficacy of 24 h urinary free cortisol (24 h UFC) in the diagnosis of subclinical Cushing's syndrome (SCS), and explore the best diagnostic cut-off value. Methods: The clinical data of patients with adrenal incidentaloma in Chinese PLA General Hospital between January 2008 and December 2016 was retrospectively reviewed and analyzed. All SCS patients were diagnosed based on the current Cushing's syndrome (CS) guidelines and confirmed by histopathology and then treated as study group, and additional patients with non-functional adrenal adenoma (NFA) were enrolled as control group. ROC curve was used to evaluate efficacy of 24 h UFC and 24 h UFC to creatinine ratio (UFCCR), and explore their best cut-off values. Results: There were 161 patients with NFA, of which contained 84 males and 77 females, with a mean age of (51.02±10.49) years old. There were 88 patients with SCS, of which contained 26 males and 62 females, with a mean age of (51.74±10.29) years old. The 24 h UFC and UFCCR levels were significant higher in SCS group than those in NFA group[510 (363, 698) nmol vs 335 (209, 467) nmol for 24 h UFC, and 7.82(4.79, 12.13) ml vs 4.82(2.41, 6.57)ml for UFCCR, both P<0.05]. ROC analysis showed that the optimal cut-off for 24 h UFC was 480 nmol (AUC 0.716, 95% CI: 0.648-0.784, with a sensitivity of 58.0% and a specificity of 79.4%) and the optimal cut-off for UFCCR was 6.84 ml (AUC 0.729, 95% CI: 0.662-0.796, with a sensitivity of 59.1% and a specificity of 78.7%). Conclusions: The recommended cut-off points of 24 h UFC and UFCCR for diagnosing SCS in AI patients were 480 nmol and 6.84 ml, respectively.

Objective: To investigate the clinical value of tumor size in the evaluation of endocrinological and histological natures regarding adrenal incidentaloma (AI) patients. Methods: A total of 1 941 AI patients who were hospitalized in Department of Endocrinology, Chinese PLA General Hospital between January 1997 and December 2016 were retrospectively reviewed. The demographics of patients, imaging features, functional status and histological results were analyzed. Results: Of 1 941 patients, 984 (50.70%) were males, and 957 (49.30%) were females. The median age was 52 years old. Endocrine evaluation according to the mass size showed that the proportion of non-functional AI and primary aldosteronism (PA) was declined from 84.55% (558/660) to 27.95% (45/161) and from 6.82% (45/660) to 0, respectively. The highest frequency of subclinical Cushing's syndrome (SCS), PA and pheochromocytomas were observed in 2.1-4.0, ≤2.0 and 4.0-6.0 cm group, respectively. Histological results showed that in>6 cm group, the frequency of malignancy were sharply increased. Multivariate logistical regression analysis indicated tumor size had a significant association with the presence of malignancy (OR=1.043, 95% CI: 1.033-1.054, P<0.001). A mass size of 4.0 cm was of great value in distinguishing malignant tumors from the benign ones, with a sensitivity of 89.19%, and a specificity of 69.91%. Conclusion: Mass size was of great value in the endocrinological evaluation, as well as distinguishing malignant tumors from the benign ones in AI patients.

Objective: To determine the effect of the surgical and conservative approaches on the metabolic profiles in patients with subclinical Cushing's syndrome (SCS) in adrenal incidentalomas (AI). Methods: A hundred and thirty AI patients with SCS in Department of Endocrinology, PLA General Hospital between January 2008 and December 2016 were studied, surgery was performed in 88 patients (surgical group), and the rest received conservative approach (conservative group). The improvement/worsening of blood pressure, blood glucose, lipid profiles and body weight after a duration of >18 months follow-up were analyzed, respectively. Results: Baseline demographics, clinical characteristics were similar between surgical and conservative groups. In the surgical group, blood pressure, blood glucose, lipid profiles and body weight improved more frequently than that in conservative group (29.69% vs 3.12%, P=0.003; 10.94% vs 3.12%, P=0.262; 7.81% vs 3.12%, P=0.660; 39.06% vs 9.38%, P=0.004, respectively). In conservative group, blood pressure, blood glucose, lipid profiles and body weight worsened more frequently than that in surgical group (28.13% vs 0, P<0.001; 25.0% vs 0, P<0.001; 18.75% vs 0, P=0.003; 40.62% vs 20.31%, P=0.051, respectively). Logistic regression analysis indicated surgical treatment was associated with improvement of blood pressure (OR=10.687, 95%CI: 1.279-89.299) and weight loss (OR=5.541, 95%CI: 1.404-21.872) independently of gender, age, duration of follow-up, serum cortisol level after 1 mg-dexamethasone suppression test and the mass size. Conclusion: In AI patients with SCS, surgery was beneficial in the aspect of metabolic profiles.
