1.Clinical and imaging characteristic analysis of 4 cases of reversible posterior encephalopathy syndrome
Chinese Journal of Neurology 2005;0(08):-
Objective To investigate clinical and MRI features of the reversible posterior encephalopathy syndrome (RPES).Methods Clinical and MRI materials of 4 RPES cases confirmed by integrated clinical diagnosis were retrospectively analyzed.Results All the cases presented with a rise of blood pressure.The neural symptom include severe headache (2 cases),dysphoria (3 cases),blur of vision (2 cases),impairment of impermanent memory (1 case),seizure (2 cases).In MRI,the lesions mainly systematically located in posterior parietal lobe and occipital lobe in all cases,or randomly located in frontal lobe (2 cases).Lesions demonstrated high signal on T_2 weighed and water-suppressed sequences in MRI.The lesions dominantly located in cortex in 2 cases,in both cortex and subcortieal white matter in 1 case and in subcortical white matter in 1 case.Four cases resolved their lesions when re-examined. Conclusions RPES represents such characteristic MRI findings as symmetrical distribution of reversible lesions in posterior brain with involvement of cortex or subcortieal white matter.When combined with hypertension and neural symptoms caused by involvement of posterior brain structure,it is helpful for early differential diagnosis of this syndrome.

The detection of blood flow velocity has great significance for blood vessel monitoring and the research of cardiovascular pathogenesis. Blood flow velocity measurement based on ultrasonic is becoming more and more popular in doctors and patients compare to several other techniques in nowadays, as they are non-invasive, cheap and fast. Most of the traditional ultrasonic blood flow velocity measurement methods are based on the Doppler frequency shift, but theses methods have some limitations, such as angle dependence, limited spatial resolution and so on. Therefore, blood flow velocity techniques based on non-Doppler frequency shift also get rapid development in recent years. This article mainly summarizes the techniques of blood flow velocity estimation based on ultrasonic in these two aspects.

Objective: To measure the level of T-lymphocyte subsets and immunoglobulin in severe traumatic brain injury and to explore the clinical significance. Method: 48 cases with severe traumatic brain injury were measured in T-lymphocyte subsets and immunoglobulin of vein blood before and after the rehabilitation therapy. By comparing with the control group and combining clinical evaluation to analyze the immune functional state in the state of TBI and the prognosis. Result:The cellular and humoral immune were inhibited distinctly. The level of CD3 + ,CD4 + ,CD4 +/CD8 +, IgG and IgA of TBI group were lower than the level of the control group. In prognosis, the early immune state of severe disability+vegetable state group was inhibited more seriously than good recovery + mild disability group. Conclusion: The cellular and humoral immune of severe traumatic brain injury were in inhibited state. The severe inhibition of immune, the worse the prognosis.

Objective To investigate the changes of cerebral regional glucose metabolism and regional homogeneity (ReHo) and their relation in patients with major depression disorder (MDD) using 18F-FDG PET/CT and functional MRI (fMRI).Methods A total of 18 MDD patients (6 males,12 females,age:(33.00±7.59) years) and 17 healthy controls (6 males,11 females,age:(34.59±8.96) years) underwent 18F-FDG PET/CT and fMRI.The changes of glucose metabolism on PET and ReHo on fMRI were analyzed individually by SPM and ReHo fMRI 1.0 software.Pearson correlation analysis was used.Results Compared with the glucose metabolism of control subjects,those of MDD patients decreased in the bilateral superior,middle and inferior frontal gyri,bilateral superior and middle temporal gyri,bilateral anterior cingulate cortices,bilateral putamina and caudate nuclei and the left pallidum.Meanwhile the glucose metabolism increased in the bilateral hippocampi and the left thalamus.The ReHo in MDD patients decreased in bilateral superior and middle frontal gyri,left pallidum,bilateral putamina,left anterior cingulate cortex,whereas increased ReHo was found in right hippocampus and right thalamus.The SUV of bilateral superior,middle and inferior frontal gyri,bilateral superior and middle temporal gyri,bilateral putamina,left caudate,left pallidum,left anterior cingulate cortex,bilateral hippocampi and bilateral thalami were correlated with ReHo (r =0.51-0.83,all P<0.05).However,no correlation was found between the SUV and ReHo in right caudate and anterior cingulate cortex (r=0.41,0.37; both P>0.05).Conclusion There may be relative characteristic models of abnormal cerebral metabolism and cerebral dysfunction impairment in MDD patients,and the changes of cerebral regional glucose metabolism may be correlated with the changes of ReHo.

Objective To observe the therapeutic efficiency of naoxintong capsule on the patients with moderate obstructive sleep apnea hypopnea syndrom ( OSAHS ) of cognitive dysfunction. Methods Sixty pa?tients of moderate OSAHS were randomly divided into treatment group and control group, 30 cases in each group. Patients in the treatment group were given naoxintong capsule,three goals,three times a day,at the same time,with double level positive pressure ventilation therapy for 3 months. Patients in the control group accepted double level positive pressure ventilation therapy for 3 months. The questionnaires of Montreal Cognitive Assess? ment( MoCA) were administered to assess cognitive in all the patients before and after treatment. Results There was no statistically significant difference in term of MoCA score between the two groups before treatment( t=0. 14,P>0. 05). After treatment,the MoCA score of the treatment group was (25. 83+1. 70),of control group was (22. 70+2. 51),the difference was statistically significant(t=5. 62,P<0. 05).

ROS-mediated oxidative stress involved in a variety of cellular signal transduction, FOXO3a transcription factor is an intersection in regulating a variety of cellular oxidative stress. FoxO3a has been extensively studied in regulating oxidative stress because of its rather complex and pivotal regulation of cell proliferation, cell cycle arrest, ROS scavenging and apoptosis. This review will elucidate the FOXO3a’s regulatory mechanisms and describe the target genes involved. It will also provide the clinical significance and strategies to target FOXO3a to regulate oxidative stress.
