Also, the animal study showed a similar antitumor effect between treatment with TRAIL-Mu3 every other day and three time a week, which was better than daily use. All treatments significantly suppressed the growth of xenograft tumor, increased the expression or activity of DR4 and Caspase-3, and down-regulated the expression of XIAP ( P less then 0.05). Conclusion TRAIL-Mu3 could improve antitumor activity in vivo and in vitro through elevating DR4 expression, activating Caspase-3/-8, and inhibiting XIAP activation.Objective To investigate the clinical characteristics of aldosterone producing adenoma (APA) and idiopathic hyperaldosteronism (IHA) complicated with obstructive sleep apnea hypopnea syndrome (OSAHS) and the effect of OSAHS on renin-angiotensin-aldosterone system (RAAS) in APA and IHA patients. Methods The clinical data of 127 patients with primary aldosteronism (PA) diagnosed from May 2010 to Aug. 2019 were retrospectively analyzed. There were 70 cases of APA, 53 cases of IHA. Another 4 cases were primary adrenal hyperplasia (PAH), so not included into further analysis. According to the results of polysomnography, the 123 patients of APA or IHA were divided into OSAHS group (96 cases) and non-OSAHS group (27 cases ). The patients with OSAHS were divided into mild, moderate and severe subgroups based on apnea hypopnea index (AHI).The clinical characteristics, biochemical parameters, plasma renin activity, aldosterone levels, and the ratio of aldosterone to renin activity (ARR) in the patients of APA and IHA cly higher in the patients with PA than normal population, and OSAHS may aggravate glycose, lipid and uric acid metabolism in PA patients. https://www.selleckchem.com/products/s961.html Moderate/severe OSAHS can increase renin levels and decrease ARR values in APA patients, but has no significant effect on RAAS in IHA patients.Objective To summary the clinical diagnosis and treatment of primary aldosteronism (PA) in West China Hospital (WCH) of Sichuan University during 2009-2018. Methods This study enrolled the patients diagnosed as PA and admitted in WCH of Sichuan University from January 2009 to December 2018. The information of the patients including epidemiological and clinical data, diagnosis and treatment as well as therapeutic outcomes were collected and analyzed. Results A total of 853 patients with 1 248 diagnostic cases were included in the analysis, and the diagnosis cases of PA increased year by year from 2009 to 2018. Most patients (74.33%) were confirmed the diagnosis in the Department of Endocrinology and Metabolism and then admitted to the hospital. PA was more frequent in female than in male, with a ratio of female to male about 1.34∶1. Hypertension was the most common chief complaint, in contrast, the proportion of fatigue and/or numbness as the symptoms of hypokalemia was declining. More and more patients were diagnosed because of imaging examination founding adrenal incidentoma. After 2016, more and more patients were diagnosed by recumbent saline suppression test and captopril challenge test, and the number of adrenal venous sampling to classify PA subtypes was increasing to help choosing different treatment options. The proportion of surgical treatment decreased year by year, and more and more patients adopted medical treatment or transferred to surgery with combined treatment instead of simple operation. Conclusion During the past 10 years, remarkable progress was made in the diagnosis and treatment of PA. Hypertension was the most important clinical manifestation of PA, so the screening of PA in hypertensive patients should be strengthened. Adrenal incidentaloma has become prevalent manifestation of PA with an increasing trend, which needs more attention in clinical practice.Objective To explore the electrolyte characteristics between different types of primary aldosteronism (PA), especially the value of serum potassium and the ratio of sodium to potassium after saline infusion test (SIT) in differential diagnosis of PA. Methods The clinical data was collected from 135 patients who received screening for the causes of hypertension from Jan. 2009 to Dec. 2018 in West China Hospital. The patients were divided into two groups essential hypertension group (EH group, 34 patients) and primary aldosteronism group (PA group, 101 patients). PA patients were divided into aldosterone-producing adenoma group (APA group, 60 patients) and idiopathic hyperaldosteronism group (IHA group, 41 patients). To analyze the value of serum potassium and the ratio of sodium to potassium after SIT in the differential diagnosis of PA with receiver operating characteristic (ROC) curve. Results Compared with EH group, the serum potassium level of APA group was lower either before or after SIT ( P less then 0.s of PA.Objective To investigate the the feasibility and diagnostic efficiencyvalue of different screening indexesmethods for screening primary aldosteronism (PA). Methods The clinical data of 499 patients with PA and 479 patients with essential hypertension diagnosed from Jan. 2009 to Dec. 2018 were retrospectively analyzed. The diagnostic performance of different screening indexs was compared by plotting receiver operating characteristic curves (ROC). Results The area under the ROC curve ( AUC) of the plasma aldosterone concentration (PAC) to plasma renin activity (PRA) ratio (ARR) was greater than that of the ratio of the upright PAC to the angiotensin Ⅱ (AT-Ⅱ) (AA2R), upright PRA, upright PAC, supine ARR, and lowest blood potassium ( P 0.05). The calibration curve of the logistic regression model is closer to the 45 ° line, and the consistency between the prediction probability and the actual probability of the logistic regression model is better than that of the decision tree model. Conclusion For the screening of PA, upright ARR seems to be the best single screening index, while AA2R (radioimmunoassay) is not recommended. The diagnostic efficacy of logistic regression model including upright PAC, PRA and lowest blood potassium is better than that of single upright ARR.Primary aldosteronism (PA) is the most common cause of secondary hypertension. The diagnosis procedure of PA includes screening, confirmatory diagnosis and subtype classification. International and national guidelines recommended plasma aldosterone concentration (PAC) to plasma renin activity (PRA) ratio (ARR) to detect possible cases of PA, and one or more tests (fludrocortisone suppression test, saline infusion test, oral sodium loading test, or captopril challenge test) to confirm ARR positive patients. Adrenal venous sampling (AVS) is also recommended as the best method to distinguish unilateral and bilateral adrenal disease when surgical treatment is feasible and desired by the patient. However, many studies find that each of the above diagnostic method has shortcomings. Recently, more and more studies are attempting to explore new methods with higher diagnostic efficiency and more conveniences, including new screening tests, new confirmatory diagnostic tests, new imaging and pathological histology methods.
