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 observe the effect of acupoint injection with Neostigmine Methylsulfate at Zusanli (ST 36) on gastrointestinal function of patients after laparoscopic cholecystectomy. Methods:Totally 120 patients undergone laparoscopic cholecystectomy were randomized into an acupoint injection group, a muscular injection group, and a blank control group at 1:1:1 by random number table, 40 cases in each group. The blank control group was intervened by conventional post-operation treatment, the acupoint injection group was by acupoint injection with Neostigmine Methylsulfate 2 mL at bilateral Zusanli (ST 36) in addition to the treatment given to the blank control group, and the muscular injection group was by muscular injection with Neostigmine Methylsulfate 2 mL in addition to the treatment given to the blank control group. The two injection groups both received injection twice a day, totally for 3 d at most. The restored time of bowel sounds, initial flatulence time, defecation time and clinical efficacy were observed. Results:After treatment, there were significant differences in comparing the restored time of bowel sounds among the three groups (F=17.30,P<0.05), the acupoint injection group and muscular injection group were significantly different from the blank control group (P<0.05), and there was a significant difference between the acupoint injection group and muscular injection group (P<0.05); there were significant differences in comparing the initial flatulence time among the three groups (F=19.12,P<0.05), and the acupoint injection group was significantly different from the muscular injection group and the blank control group (P<0.05); there were significant differences in comparing the initial defecation time among the three groups (χ2=21.23,P<0.05), while the difference between the acupoint injection group and muscular injection group was statistically insignificant (P>0.05). The total effective rate was 87.5% in the acupoint injection group, versus 72.5% in the muscular injection group and 60.0% in the blank control group, and there were significant differences among the three groups (P<0.05). Conclusion:Acupoint injection with Neostigmine Methylsulfate at Zusanli (ST 36) can shorten the restored time of bowel sounds and flatulence time in patients undergone laparoscopic cholecystectomy, and the efficacy is more significant compared to muscular injection with Neostigmine Methylsulfate.

Objective:To explore the solutions to enhance the professional skills and humanistic quality of neurosurgery in theprimary hospitals, and to improve the neurosurgery medical care level.Methods: a comprehensive analysis of the literature retrieval as well as information collected in practice the first hospital of Zhangjiakou in, extract the problems of neurosurgeon training in primary hospital, to carry out grading treatment requirements, explore the basic path to improve the clinical ability of primary hospital neurosurgeon, and through the establishment of standard clinical operating procedures and systems to ensure the quality of medical service.Results: from Wanfang database retrieved from 2006 to 2015 research journals in Chinese on improving grassroots doctors ability of 819 papers, bibliometric analysis shows that the trend is increasing year by year, in 2015 issued a number is 5.21 times in 2006. There are 28 papers including neurosurgery area, accounting for 3.42% of the total number of papers; the hot topics focus in the mode of training neurosurgery doctors in primary hospitals,transfer the technology of minimally invasive neurosurgery and spreadmodern neurosurgery theory and knowledge.Conclusion: to improve the ability of doctorsof primary hospitals should be combined with the characteristics of local diseasesand primary hospital neurosurgeon status, from making training plan, appropriate to establish the corresponding clinical standard, promote the essential neurosurgery technology, in order to ensure implementation of the tiered diagnosis and treatment .

This paper presents a case of hyperthyroidism with myasthenia gravis (MG),diagnosed by neostigmine-test.Thyrotoxicosis and clinical manifestations of MG were controlled by acetylcholinesterase-inhibitor and immuno-suppressive medicine.Being followed for more than 2 years,the patient had been free of clinical symptoms of MG and his thyroid function was normal.

Idiopathic hypogonadotropic hypogonadism (IHH) is characterized by delayed or absent puberty and lowered sexual function as a result of impaired pulsatile gonadotropin-realeasing hormone (GnRH) secretion.Identification of TAC3/TACR3 mutations as the culprits of IHH revealed that neurokinin B (NKB) signaling pathway was involved in the regulation of pulsatile GnRH secretion.This review focuses on the involvement of NKB signaling in pulsatile GnRH release,the discovery of TAC3/TACR3 mutations and the phenotypes,and treatment of patients who carry TAC3 or/and TACR3 mutations.
