Ageing of population is now a phenomenon of the world and has considerable consequences for public services.Ageing is always accompanied with dysfunction of multiple organs,including hypothalamic-pituitaryadrenal axis.Here,we summarized alterations of hormone secretion of adrenal glands in the elderly and their relationships with Alzheimer' s disease.Moreover,we discussed characteristics of pheochromocytoma,primary aldosteronism,and Cushing's syndrome in the elderly.Lack of typical manifestations usually makes difficulty in diagnosis.

Objective To investigate the injury effects and mechanisms of circulating histones on the hepatocytes in patients with hepatitis B virus (HBV )-related liver failure (HBV-LF) .Methods Serum samples from patients with HBV-LF were collected . The levels of serum histone H3 , histone H4 , prothrombin activity (PTA ) ,total bilirubin (TBil) ,creatinine (Cr) and international normalized ratio (INR) of the patients were measured .Model for end-stage liver disease (MELD) score was calculated in the patients .The serum levels of histones were compared between patients and the healthy volunteers . The correlation of histones with the MELD score and PTA was analyzed .The human liver cell line L-02 cells were cultured and treated with the serum of patients or L-02 cellular lysate supernatant preincubated with or without anti-histone H3 and H4 antibodies .The cellular morphology and rate of apoptosis were observed .Intracellular calcium ion concentration and Caspase-3 activity were detected in the cultured L-02 cells treated with histones .Mean of two independent samples was compared using t tests .Relationship between histones and the MELD score or PTA was conducted using Spearman correlation analysis .Results The levels of serum histones in the patients with HBV-LF were much higher than those in the healthy volunteers (H3 :[5 390 .3 ± 1 032 .0] μg/mL vs [42 .7 ± 12 .8] μg/mL , t = 32 .76 , P < 0 .01 ; H4 :[4 205 .1 ± 662 .3] μg/mL vs [40 .3 ± 14 .6] μg/mL ,t = 39 .74 , P< 0 .01) .In addition ,serum histones (H3/H4) levels in patients were negatively correlated with serum PTA (r= - 0 .325 ,P= 0 .038 and r =- 0 .572 ,P= 0 .028 ,respectively) ,but positively correlated with the MELD score (r= 0 .359 ,P= 0 .021 and r = 0 .568 , P = 0 .007 , respectively ) . Both serum of patients with HBV-LF and L-02 lysate supernatant were toxic to cultured L-02 cells .The injury effect was inhibited by anti-histone antibodies ([9 .3 ± 1 .5]% vs [14 .3 ± 0 .6]% , t = 4 .259 , P= 0 .02) .L-02 cells treated with calf thymus histone were cultured for 4 h . Cellular toxicity of histones resulted in Caspase-3 activation . The effect was inhibited by anti-histone antibodies ([3 .5 ± 0 .5]% vs [5 .2 ± 0 .6]% ,t= 4 .243 ,P= 0 .02) .Conclusion The elevated circulating histones in the patients with HBV-LF may aggravate the liver damage .

The utility of circulating tumor cells in breast cancer has been paid more attention. There are many clinical trials all over the world which concerned the whole course of breast cancer. Although the value of detecting circulating tumor cells is different at each stage of breast cancer, the advantage is significant compared with traditional methods in monitoring and evaluating diseases status. Nowadays the treatments of breast cancer are classiifed and individualized, it is possible to ifnd the most timely and optimized regimens after detecting the amount and characteristics of circulating tumor cells.

Objective To analyze the short term prognosis of very low birth weight (VLBW) infants. Methods The clinical data of VLBW infants who were hospitalized from December 2013 to December 2014 and followed up to 6 months of corrected age were retrospectively analyzed. Results A total of 230 VLBW infants were enrolled. Thirty infants (13.0%) died during hospitalization, 40 infants (17.4%) were given up the treatment, 60 infants (26.1%) were improved at discharge, and 100 infants (43.4%) were cured at discharge. In the 30 cases of death, causes of death were mainly neonatal respiratory distress syndrome (18 cases), pulmonary hemorrhage (5 cases), and sepsis (3 cases). In the 200 survived infants at discharge, at 6 months of corrected age of follow-up, 13 infants (6.5%) were lost to follow-up, and 54 infants (27.0%) died, among whom 40 infants died because of giving up therapeutic intervention due to economic factor or discharges without permission. At 1, 3, 6 month of follow-up, the length and weight of VLBW infants were gradually approaching normal, and, however, at 6 months of corrected age, the length and weight of VLBW infants were still obviously below the children’s growth standard. The length of VLBW infants was more deeply below the growth standard than the weight. In 109 infants who had fundus ophthalmoscope, 21 cases had retinopathy of prematurity (ROP) I, and 7 cases had ROP II. In 98 infants who had the hearing screening test, 5 cases failed in one ear and 11 cases failed in both ears. In 95 infants who had the head magnetic resonance imaging (MRI) examination, 10 cases had intracranial hemorrhage and 9 cases had premature brain injury. In 49 infants who completed the neonatal behavioral neurological assessment (NBNA) at corrected age of 42 weeks, the scores were all lower than 35. In 36 infants who were assessed by Gesell developmental scale at the 3 months of corrected age, 11 cases had mild developmental delay and 2 cases had moderate developmental delay. In 24 infants who were assessed at the 6 months corrected age, only 2 cases had mild developmental delay. VLBW infants had a rapid progress in social contact, social behavior, and gross motor movement. Conclusions Economic, neonatal respiratory distress syndrome, pulmonary hemorrhage, and sepsis are pivotal factors for the survival and quality of life of VLBW infants. The surviving VLBW infants have catch-up growth and development.
