Vascular cognitive impairment (VCI) is a large class syndrome caused by a variety of cerebrovascular diseases from mild cognitive impairment to dementia.In the VCI animal experiments,choosing a reliable test method is particularly important for evaluating animal cognitive function and the improving the quality of animal models.

Objective To investigate the expression of ACTH in normal and hyperplastic adrenal cortical tissue, and to explore the relationship between plasma ACTH concentration and expression level of ACTH in adrenal cortical tissue of patients with adrenal cortical hyperplasia. Methods The expression of ACTH in adrenal cortical tissue was examined by immunohistochemical technique, and the result was analyzed by computer-assisted image analyzing system. Besides, plasma ACTH concentration was measured by RIA. The correlation between plasma ACTH concentration and expression level of ACTH in adrenal cortical tissue of patients with adrenal cortical hyperplasia was studied. Results The expression of ACTH was significantly higher in adrenal cortical tissue of patients with ACTH-independent adrenal cortical hyperplasia than those with ACTH-dependent adrenal cortical hyperplasia and normal adrenocortical tissue (both P0.05). Conclusion ACTH expression exists in normal adrenal cortical tissue. Local ACTH overproduction appears to participate in the pathogenesis of ACTH-independent adrenal cortical hyperplasia.The raised concentration of plasma ACTH influences the expression of ACTH in cortical tissue of patients with ACTH-dependent adrenal hyperplasia.

Purpose Progressive hypertensive intracerebral hemorrhage (PHICH) is often observed in clinical ward,but its prognosis is undetermined.This study is to investigate the duration and the risk factors of progressive hypertensive intracerebral hemorrhage.Methods The diagnosis of PHICH was determined by comparing the first and second CT scans.Potential risk factors including the sex,age,location of hematoma,blood pressure,coagulopathy and the duration of admission to the first CT scan were analyzed.Results In a cohort 143 patients,the PHICH were found in 41 cases(28.7%)after the second scan,and among them,32 patients(22.4%)were necessary to perform craniotomy for evacuation of hematoma,most of the PHICH occurred within 24 hours after onset.Older age,thalamus bleeding,high systolic blood pressure within 6 hours,coagulapathy and shorter duration from admission to the first CT scan were the predictors associated with PHICH.Conclusion PHICH occurs in almost 1/4 of hypertensive intracerebral hemorrhage,predominantly in elder,thalamus bleeding,coagulapathy,high systolic blood pressure within 6 hours and shorter duration between onset and the first CT scan.CT examination within 24 hours after admission is crucial to reveal the exact condition of the patient.

Objective To evaluate effectiveness of microvascular decompression in the treatment of trigeminal neuralgia. Methods 126 cases of trigeminal neuralgia were operated on by microvascular decompression via suboccipital retrosigmoid approach. It was found that nerves were compressed by vessels nerves in 122 cases. Cotton of Teflon was implanted between oppressive trigeminal nerve roots and vessels by minimally invasive surgery. Results 113 of 126 cases were followed up postoperatively for (1～9)years. Pain disappeared or died down in 110 cases. The total effective rate was 97.3%(110/113). Conclusions Microvascular decompression is effective treatment for trigeminal neuralgia.

Objective To summary the clinical characteristics of epileptic spasm(ES)that is the unique form of seizures in childhood. Methods A total of 149 patients with ES who visited our hospital from May 2009 to June 2015 were collected. The documents of clinical data, treatment and outcome were analyzed retrospectively. The statistical analysis of some clinical characteristics and prognosis of patients were performed. Results There were 97(65.1%) male and 52 (34.9%) female in the 149 patients. The onset age of ES was from 30 days to 42 months (median value was 6 months) including 17 patients more than 12 months.The peak age of onset was 4-7 months. One hundred and forty-seven patients manifested clustered spasm. One pair of twins showed single spasm.Other types of seizure were seen before ES onset in 13 (8.7%) patients, and after ES onset in 42 (28.2%) patients.Eighty-three patients (55.7%) were diagnosed as West syndrome (WS). There were 46 patients (30.9%) with cryptogenic cause, 103 patients (69.1%) diagnosed with symptomatic epilepsy, in which 69 patients were with a clear cause. The proportions of developmental delay in the cryptogenic and symptomatic patients were 74.5% and 92.2% after the onset of the ES. The degree of developmental delay was linearly related to the course of ES. The hyperarrhythmia of electroencephalogram (EEG) background was seen in 122 patients (81.9%), and there was no significant difference in hyperarrhythmia between different etiology groups or different onset age groups. The short-term efficiency of topiramate evaluated within one month was 30.5% in 59 newly diagnosed patients. The short-term effective rate of adrenocorticotropic hormone (ACTH) was 80.3% in total 76 patients, but single ACTH treatment was associated with an increased recurrent rate. Conclusion ES is a highly age dependent seizure type that mainly found in WS,which typically follows a EEG hyperarrhythmia and developmental delay. The treatment of ES is difficult. ACTH combined with effective antiepileptic drugs (AEDS) is currently the most reasonable drug treatment program.

Objective To summarize the clinical features and transsphenoidal microsurgical experiences of pituitary adenomas in the elderly patients over 70 years old Methods Twenty four elderly patients accepted transsphenoidal microsurgery were conductded a retrospective review,whose clinical data including clinical main presentation,histological types,surgical conditions,perioperative treatment and outcome were also analyzed Results There were 16 non functional adenomas (66 7%) and 18 giant macroadenomas(75%) respectively Visual deterioration was the commonest complain in 20 (83 3%) Despite the majority of patients having coexisting medical conditions,we had no mortality and no postoperative adjunctive morbidity with an average hospital stay of 17 8 days For an average follow up of 3 5 years,we did observe major patients(79 2%) vision had improved Conclusions Pituitary adenomas in the elderly are most frequently non functional macroadenomas that present with visual deterioration and hypopituitarism If special care is devoted to the perioperative treatment,in particular to fluid and electrolyte balances,transsphenoidal microsurgery is safe and effective in hands of an experienced team

This paper is to evaluate the biocompatibility and cytotoxicity of a new Ni-free Zr-based bulk metallic glass (BMG), Zr60.14 Cu22.31 Fe4.85 Al9.7 Ag3, by comparing it with conventional Ti6Al4V alloy. According to ISO 10993-5: 1999 and GB/T 16886.5-1997 standards, Zr60.14 Cu22.31 Fe4.85 Al9.7 Ag3, pure Zr and Ti6Al4V materials were extracted with surface area of sample/volume of medium ratio being 1 cm2/mL and 0.5 cm2/mL, respectively. The viabilities of MG-63 cells (Human osteosarcoma cell line) cultured in the BMG medium extracts for 1, 3 and 5 days were determined by CCK-8 assay. The cellular morphology of MG-63 cells cultured on the surface of samples for 3 days was tested through laser scanning confocal microscopy (LSCM) and scanning electron microscopy (SEM). The relative growth rate (RGR) of MG-63 cells cultured in Zr60.14 Cu22.31 Fe4.85 Al9.7 Ag3 and pure Zr were both more than 85%, indicating that the cytotoxicity of BMG was relatively low and met the national biomedical material eligibility standard. There was insignificant difference in the morphology of MG-63 cells cultured in the BMG medium extracts and the control group through LSCM and SEM, which showed the BMG had excellent biological compatibility. The Zr-based bulk metallic glass Zr60.14 Cu22.31 Fe4.85 Al9.7 Ag3 and the conventional Ti6Al4V alloy both had no obvious cytotoxicity to MG-63 cells. These results provided evidence that the new Zr-based bulk metallic glass could be potential replacement material for the orthopedic surgical implant.
