Cognitive profile in mild cognitive impairment with Lewy bodies

INTRODUCTION@#This study aimed to elucidate the cognitive profile of patients with mild cognitive impairment with Lewy bodies (MCI-LB) and to compare it to that of patients with mild cognitive impairment due to Alzheimer's disease (MCI-AD).@*METHODS@#Subjects older than 60 years with probable MCI-LB (n = 60) or MCI-AD (n = 60) were recruited. All patients were tested with Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) to assess their global cognitive profile.@*RESULTS@#The MCI-AD and MCI-LB patients did not differ in total MMSE and MoCA scores. However, some sub-items in MMSE and MoCA were shown to be screening markers for differentiating MCI-LB from MCI-AD. In the visuoconstructive test, the total score and hands subitem score in the clock-drawing test were significantly lower in MCI-LB than in MCI-AD. As for the executive function, the 'animal fluency test', 'repeat digits backward test' and 'take paper by your right hand' in MMSE all showed lower scores in MCI-LB compared with MCI-AD. As for memory, 'velvet' and 'church' in MoCA and 'ball' and 'national flag' in MMSE had lower scores in MCI-AD than in MCI-LB.@*CONCLUSION@#This study presents the cognitive profile of patients with MCI-LB. In line with the literature on Dementia with Lewy bodies, our results showed lower performance on tests for visuoconstructive and executive function, whereas memory remained relatively spared in the early period.

Single-stranded adeno-associated virus serotype 9 mediated gene expression in astrocyte via intravenous delivery / 上海交通大学学报（医学版）

Objective: To investigate the expression of LacZ gene mediated by intravenous injection of the single-stranded adeno-associated virus serotype 9 (ssAAV9) containing hypoxia-responsive element (HRE) promoter in the cerebral ischemic area, and further identify the types of brain cells that can be transfected by the vector. Methods: A mouse model of permanent left distal middle cerebral artery occlusion (dMCAO) was established. The expression of hypoxia-inducible factor-1 (HIF-1) in cerebral ischemic area was detected at 1 and 5 days after ischemia. The ssAAV vector containing HRE-regulated LacZ gene was packaged into the capsid of AAV9 virus (AAV9-H9LacZ), and AAV9-H9LacZ was injected into mice through jugular vein 1 h after the establishment of dMCAO model. Five days after injection of AAV9-H9LacZ, X-gal staining was used to detect the expression of β-galactosidase (β-gal) encoded by the LacZ gene in the ischemic area and liver tissue. Immunofluorescence double staining was used to detect the expression of β-gal in astrocyte, neurons and vascular endothelial cells. Results: The expression of HIF-1 was increased 1 and 5 days after ischemia. β-gal was mainly expressed in ischemic penumbra of mice injected with AAV9-H9LacZ. There was no positive expression of β-gal in the liver tissue of mice. β-gal was mainly co-expressed with glial fibrillary acidic protein as an astrocyte-specific marker, and a little of β-gal was co-expressed with neuron-specific nuclear protein. Conclusion: After cerebral ischemia, intravenous injection of AAV9-H9LacZ can effectively mediate gene expression in astrocyte in the cerebral ischemia area. HRE can effectively control the expression of the LacZ gene in cerebral ischemia.

Correlations of Four Genetic Single Nucleotide Polymorphisms in Brain-Derived Neurotrophic Factor with Posttraumatic Stress Disorder

OBJECTIVE: To investigate the correlations of four genetic single nucleotide polymorphisms (SNPs) of brain-derived neurotrophic factor (BDNF) with posttraumatic stress disorder (PTSD). METHODS: A total of 300 patients with sporadic PTSD and 150 healthy subjects (the control group) were selected according to the diagnostic criteria of PTSD (DSM-IV), and the genotypes of the BDNF SNPs G-712A, C270T, rs6265, and rs7103411 were detected by polymerase chain reaction and direct DNA sequencing to determine intergroup differences in the genotypes and allele frequencies; the p values were corrected with the permutation test. RESULTS: The genotypes and allele frequencies of the SNPs G-712A, rs6265, and rs7103411 of BDNF showed no significant intergroup differences (p>0.05). However, the genotype and allele frequencies of C270T showed significant differences between the PTSD group and the control group (p<0.05). CONCLUSION: The SNP C270T of BDNF may be associated with PTSD. Individuals carrying the polymorphic T allele of C270T may be more likely to suffer from PTSD.

Research progress of measures for renal perfusion adjustment in sepsis patients / 解放军医学杂志

Sepsis is the result of systemic inflammatory reaction induced by bacteria, virus or fungus infection, and it can lead to shock, multiple organ dysfunction syndrome, and even death. It has become the main cause for death of the patients in intensive care unit (ICU). Acute kidney injury (AKI) is one of the most common, and the most serious complications in the course of sepsis, and it is characterized by acute renal failure (ARF). The incidence of AKI would climb with the severity of sepsis, and it is significantly more eminent than the other factors. Along with the advancement in the research on sepsis, a new understanding in the treatment of renal injury caused by sepsis is gradually obtained, and attention is given to the improvement of renal perfusion. In this review, we review the measures for adjusting the renal perfusion.

To investigate the urination-reducing effect and mechanism of Zhuangyao Jianshen Wan (ZYJCW). In this study, SI rats were subcutaneously injected with 150 mg · kg(-1) dose of D-galactose to prepare the sub-acute aging model and randomly divided into the model group, the Suoquan Wan group (1.17 g · kg(-1) · d(-1)), and ZYJCW high, medium and low dose groups (2.39, 1.20, 0.60 g · kg(-1) · d(-1)) , with normal rats in the blank group. They were continuously administered with drugs for eight weeks. The metabolic cage method was adopted to measure the 24 h urine volume and 5 h water load urine volume in rats. The automatic biochemistry analyzer was adopted to detect urine concentrations of Na+, Cl-, K+. The ELISA method was used to determine serum aldosterone (ALD) and antidiuretic hormone (ADH). The changes in P2X1 and P2X3 mRNA expressions in bladder tissues of rats were detected by RT-PCR. According to the results, both ZYJCW high and medium dose groups showed significant down-regulations in 24 h urine volume and 5 h water load urine volume in (P <0.05, P <0.01), declines in Na+ and Cl- concentrations in urine (P <0.01), notable rises in plasma ALD and ADH contents (P <0.05, P <0.01) and remarkable down-regulations in the P2X1 and P2X3 mRNA expressions in bladder tissues (P <0.01). The ZYJCW low dose group revealed obvious reductions in Na+ and Cl- concentrations in urine (P <0.01). The results indicated that ZYJCW may show the urination-reducing effect by down-regulating the P2X1 and P2X3 mRNA expressions in bladder tissues of rats with diuresis caused by kidney deficiency.

The transport of gastrodin in Caco-2 cells and uptake in Bcap37 and Bcap37/MDR1 cells / 药学学报

Gastrodin (GAS) is the major bioactive component of the extracts from the rhizome of Gastrodia elata Blume. The aim of this study is to investigate the transport of GAS in Caco-2 cells and the interaction of P-glycoprotein and GAS. The apparent permeability coefficients (Papp) of GAS were measured as a function of directions and concentrations. It was demonstrated that the efflux ratio was < 2.0 over the range of 50-500 micromol x L(-1) of GAS from bi-directional transport studies. The transport rate of GAS was dependent on the concentrations. Papp of GAS was not affected by transport directions, GAS concentration or the classical inhibitors of P-glycoprotein (verapamil and GF 120918). The cellular accumulation of GAS in Bcap37/MDR1 cells transected with hMDR1 gene, was similar to that in Bcap37 cells. The accumulation in both cell lines was concentration dependent. GAS did not affect the accumulation of Rhodamine 123 in Bcap37/MDR1 cells over the range of 50-500 micromol x L(-1). It indicated that the transport of GAS in Caco-2 cell monolayers mainly is by passive paracellular transport pathway. P-glycoprotein did not participate in the absorption of GAS in the intestine or the transport across the blood-brain barrier.
