Objective:To analyze the relationship between electroencephalogram(EEG)reactivity and early neurological deficits in elderly acute cerebral infarction(ACI)patients with cerebral microbleeds.Methods:Clinical data were collected from 51 elderly ACI patients with cerebral microbleeds admitted to our hospital from July 2018 to April 2020, who formed the ACI with cerebral microbleeds group, and were retrospectively analyzed.The ACI group was composed of 47 patients with ACI treated at our hospital during the same period.All patients underwent EEG examination.EEG reactivity, sleep waves and other signs were monitored.Early neurological deficits were recorded 2 hours after thrombolysis in elderly ACI patients with cerebral microbleeds, assessed using the National Institutes of Health Stroke Scale(NIHSS), and divided into subgroups.Baseline data and EEG-related findings were compared between the two groups.The relationship between the severity of early neurological deficits and EEG reactivity was analyzed.Results:EEG reactivity and the positive detection rate for sleep waves were lower(33.33% or 17/51 vs.65.96% or 31/47, 27.45% or 14/51 vs.61.70% or 29/47, χ2=10.417 and 11.652, P=0.000 and 0.001)and early neurological deficits were more serious( Z=2.381, P=0.017)in the ACI with cerebral microbleeds group than in the ACI group.The proportions of cases with EEG reactivity and negative sleep waves were higher(91.18% or 31/34 vs.8.82% or 3/34, 86.49% or 32/37 vs.13.51% 5/37, χ2=17.771 and 13.147, both P=0.000)and the levels of vWF were lower(6.24±1.79 mg/L vs.13.48±2.23 mg/L, t=12.039, P=0.000)in elderly patients with moderate and severe ACI accompanied by cerebral microbleeds than in elderly patients with mild ACI accompanied by cerebral microbleeds.Logistic regression analysis showed that absence of EEG reactivity( OR=18.994, P=0.000), negative sleep waves( OR=11.520, P=0.001)and low levels of vWF( OR=0.283, P=0.001)were correlated with the degree of early neurological deficits in elderly ACI patients with cerebral microbleeds, with absence of EEG reactivity having the most significant impact.The results of receiver operating characteristic(ROC)curve showed that the area under the ROC curve(AUC)of absent EEG reactivity for predicting early moderate and severe neurological impairment was 0.803(95% CI: 0.650-0.956, P<0.001), indicating a certain degree of predictive value. Conclusions:Elderly ACI patients with cerebral microbleeds are associated with different degrees of functional neurological deficits in early stages, and the degree of neurological deficits may be related to absence of EEG reactivity.In the future, EEG reactivity may be considered as a risk assessment tool for the progression of neurological deficits in elderly ACI patients with cerebral microbleeds.

Objective To investigate the differential diagnosis of early-stage Parkinson disease(PD) and vascular Parkinsonism(VP) by 99Tcm-TRODAT-1 single photon emission computed tomography brain imaging.Methods 99Tcm-TRODAT-1 SPECT brain imaging was performed on 47 patients with early-stage PD,26 with early-stage VP and 30 age-matched healthy control subjects.The radioactive ratio of striatum to cerebullum was calculated by region of interest(ROI) technique.The results were analyzed and compared.Results The distribution and quantities of 99Tcm-TRODAT-1 uptake were reduced in contralateral striatum to clinically symptomatic side of the patients with early-stage PD(P0.05).The radioactive ratio of striatum to cerebullum contralateral to the affected limb in the patients with early-stage PD was lower than that in the healthy control subjects while that to patients with early-stage VP were similar to that in the healthy control subjects.Conclusion 99Tcm-TRODAT-1 single photon emission computed tomography brain imaging and semiquantitative analysis are useful to differentiate VP from PD.

Objective To explore the expression and significance of TGF-β1 and CTGF in the occurrence and development of patients with subarachnoid hemorrhage. Methods Cerebrospinal fluid TGF-β1 and CTGF concentrations in all subjects were serially detected by ELISA. Results Mean total TGF-β1 and CTGF in patients were elevated more than that in controls at the first day(P＜0.05).Thereafter the levels of TGF-β1 and CTGF fell by the third day, then rose to the second peak at the tenth day and remained significantly increase until the sixteenth day(P＜0.05).The levels of TGF-β1 was positive correlated CTGF. Conclusion The expressions of TGF-β1 and CTGF in patients with subarachnoid hemorrhage showed two peaks character. After SAH, the concentration of TGF-β1 and CTGF concentration is related to chronic communicating hydrocephalus.

PNAS-4 is a novel pro-apoptosis gene identified latetly. In recent years, there has been a large number of research reports on the basic studies about PNAS-4 in cancer gene therapy and gene therapy of PNAS-4 alone or combined with chemotherapy or radiotherapy manifested a good application prospect, but its molecular mechanisms to promote apoptosis is not clear yet. In this paper, recent research about PNAS-4 in cancer gene therapy is briefly reviewed, and recent hypotheses on its molecular mechanisms to promote apoptosis are especially elucidated. Based on its newly identified characteristics of structural domain, we made a point that PNAS-4 might regulate functions of some target protein related to apoptosis by deSumoylation as a new deSumoylating isopeptidase, and consequently promote apoptosis.
