Objective To investigate changes of metabolic syndrome (MS ) in patients with adrenocortical adenoma (ACA ). Methods Sixty‐five patients with aldosterone producing adenoma (APA) ,43 patients with cortisol‐secreting adenoma (CSA) and 24 patients with nonfunctional adrenal adenoma (NAA) were evaluated. Body Mass Index (BMI) ,blood pressure ,plasma lipid ,fasting and 2 h postprandial plasma glucose ,plasma and urinary aldosterone ,plasma potassium ,basic and upright plasma renin activity (PRA ) ,plasma and urinary cortisol ,plasma ACTH and plasma potassium ACA were examined and compared with those from 53 patients of essential hypertension (EH ) and 58 controls. Adrenalectomy was performed for all the patients with adrenocortical adenoma. The data after operation were compared with those before operation. Results (1) The prevalence of MS was 38.5% ,41.9% , 20.8% ,24.5% and 17.5% in the groups respectively. The prevalence of obesity/overweight was higher in CSA group than in the other groups. There were 44.6% patients with hyperglycemia in APA group ,and 48.8% in CSA group. The prevalence of hypertension was the highest in APA and EH group ,followed by CSA group ,NAA and control groups. There were 55.4% patients with lipid disturbance in APA group , and 46.5% in CSA group. (2 ) We divided all APA and CSA patients into groups with or without MS. The APA patients with MS had higher plasma aldosterone than those without MS. The CSA patients with MS had higher 08 :00 and 24 :00 plasma cortisol than those without MS. (3) After operation ,the plasma and urinary aldosterone were decreased and the plasma potassium was increased in APA patients. The 08 :00 ,24 :00 plasma cortisol and urinary cortisol were decreased and the 08 :00 plasma ACTH was increased in CSA patients. There were no significant differences in hormonal measurements of NAA patients before and after operation. (4 ) The prevalence of MS was 27.7% ,27.9% and 29.2% in three groups after operation. The systolic and diastolic blood pressures were decreased in APA patients after operation ,and the systolic blood pressure decreased in CSA patients. There was no significant difference in MS measurements of NAA patients before and after operation. Conclusions Our study indicates that patients with functional adrenocortical adenoma have a significantly higher prevalence of metabolic syndrome which is related to over secretion of adrenal cortex hormone. After operation ,accompanying normalization of hormonal secretion ,the condition of MS in functional adrenocortical adenoma patients is improved.

Cancers of the digestive system account for a large portion of malignant tumors in humans,and the trend is on the rise.The formation of neovascularization is the dominant factor in the metastasis of tumors.The vascular endothelial growth factor(VEGF) is well documented as the most potent inducer of angiogenesis.It promotes the formation of new blood vessels in several aspects,such as proliferation of endothelial cells,endothelial cell migration and increased vascular permeability.So VEGF is regarded as an important factor in the development of digestive system tumors.The purpose of this review is to investigate the relationship between VEGF and digestive system tumors.

Objective:To investigate the relationship between college freshman adaptation and adverse childhood events,and to explore the mediating role of personality characteristics.Methods:A sample of 523 college freshmen from a key university in Sichuan Province was assessed with the China College Student Adjustment Scale (CCSAS),Adverse Childhood Events Questionnaire (ACEQ) and Eysenck Personality Questionnaire-Revised,Short Scale for Chinese(EPQ-RSC).Results:The rate of adverse childhood events of college freshmen was 87％ in current study.The total scores of adaptation were negatively correlated with the scores of adverse childhood events influence and neuroticism (r ＝-0.13,-0.51,Ps ＜ 0.01),while positively correlated with introversion-extroversion and lie (r ＝ 0.47,0.25,Ps ＜ 0.01).The scores of adverse childhood events influence were negatively correlated with scores of introversion-extroversion (r ＝-0.08,P ＜0.05) and lie (r ＝-0.12,P ＜0.01),while positively correlated with scores of neuroticism (r ＝ 0.17,P ＜ 0.01).Introversion-extroversion and neuroticism mediated the relationship between adverse childhood events influence and college freshman adaptation,the mediating effects were 51.65％ and 58.10％.Conclusion:College freshman adaptation may be closely associated with adverse childhood events influence and personality characteristics.Personality characteristics may play a mediating role between adverse childhood events influence and adaptation in college freshman.

BACKGROUND: Transcranial Doppler(TCD) spectrum analysis techniques cannot measure the diameters of blood vessels and therefore and not be used to calculate the changes of brain blood flow. A formula was designed for regional cerebral blood flow loss index(rCBFLI) following arteriostenosis when arteriostenosis index formula was deduced; the former may provide a reference to assess cerebral function.OBJECTIVE: To introduce the formula of cerebral blood flow loss ratio obtained basing on TCD results.DESIGN: Retrospective controlled study based on patients with cerebral middle arteriostenosis diagnosed with TCD and healthy people.SETTING: At the departments of neurology in a university hospital and in a military medical university affiliated hospital of Chinese PLA.PARTICIPANTS: Between October 1994 and December 2000,43 patients who were confirmed of arteriostenosis with TCD at outpatient or neurological ward of the First Affiliated Hospital of Fujian Medical University were enrolled into this study,and their TCD results were compared with 908 normal controls between March 1992 and September 2000.METHODS: Stenosis index (STI) formula was deduced from TCD results of 31unilateral and 12 bilateral stenoses at middle cerebral artery(MCA) . STI = 1- [ normal average blood velocity (Vm0) ÷ average blood velocity at stenosisSince(PI1 ÷PI0) may be equal to [post-stenosis blood flow(Q1) ÷ normal blood flow(Q0)],regional cerebral blood flow loss index is concluded as:MAIN OUTCOME MEASURES: rCBFLI,relationship between STI and Vm,as well as between rCBFLI and STI.RESULTS: rCBFLI formula was used to calculate the rCBFLI of 31 patients following unilateral MCA stenosis. rCBFLI of these 31 patients was obtained by Pearson statistical analysis. STI was found to be related to the average blood velocity at stenosis with relative coefficient(Vm) of(r) =0.76( P ＜ 0. 001 )and r = 0. 83 ( P ＜ 0. 001 ) . rCBFLI was proved to be correlated with Vm and STI with r = 0. 76( P ＜ 0. 01 ) and r = 0. 81 in 55 side MCA stenoses,and the difference was of statistical significance( P ＜ 0. 001 ).CONCLUSION: rCBFLI can be used to assess the decrement of regional brain blood flow due to the stenosis of supplying artery; also,it can be used to observe the changes of brain hemodynamics if combined with STI.

Objective To investigate the prevalence of year-round respiratory viral infection in children with lower respiratory tract infection (LRTI), and the relationship between respiratory viral infection and allergen sensitization in exacerbating asthma. Methods A total of 231 hospitalized children with acute LRTI were investigated from May 2013 to April 2014. The 5 most common respiratory viruses were isolated from nasopharyngeal aspirate using multiplex reverse transcription-polymerase chain reaction, including respiratory syncytial virus (RSV), adenovirus (AV), parainfluenza virus (PIV), influenza virus (IFV) and rhinovirus (RV). Atopic sensitization was defined if more than 1 serum specific immunoglobulin E level measured using immunofluorescence experiment was over 0.35 IU/mL. Results RSV was the most common pathogen of bronchiolitis in hospitalized children through the year. RV or IFV infections were more prevalent in asthma exacerbations compared to other LRTIs. AV was more likely to cause pneumonia. RV and IFV were associated with asthma exacerbations in children with atopic sensitization, but not in nonatopic children. Conclusion RV and IFV are associated with hospitalization for asthma exacerbation in children with atopic sensitization.
