BACKGROUND:Isoflurane is an anesthesia drug that has a certain effect on the nervous system. It possibly causes neurologic disorders through impacting nerve stem cel function or morphology. OBJECTIVE:To investigate the effects of isoflurane on the proliferation and differentiation of neural stem cels in the hippocampus of rats. METHODS:Neural stem cels from the hippocampus of neonatal Sprague-Dawley rats, aged 7 days, were induced and differentiated. Passage 3 cels were obtained and divided into two groups: isoflurane group (a mixture gas of 2.8% isoflurane, 5% CO2 and 95% O2) and control group (a mixture of 5% CO2 and 95% O2).
After intervention of 6 hours folowed by 2 hours of routine culture, anti-BrdU monoclonal antibody immunofluorescent staining was used to detect cel proliferation, and western blot assay to detect the expression of β3-tubulin and glial fibrilary acidic protein. RESULTS AND CONCLUSION:Compared with the control group, the number of BrdU positive cels in the isoflurane group reduced significantly, indicating that isoflurane inhibits the proliferation of neural stem cels. Compared with the control group, the expression of glial fibrilary acidic protein in the isoflurane group up-regulated, but the expression of β3-tubulin had no changes, indicating isoflurane promotes the differentiation of neural stem cels into astrocytes.

Objective To analyze the clinical characters and identify the risk factors in patients diagnosed with systemic lupus erythematosus (SLE) and thrombotic thrombocytopenic purpura (TTP). Methods We retrospectively analyze the clinical features, laboratorial test results and treatment strategy of 20 SLE patients with TTP diagnosed in the First Affiliated Hospital of Zhengzhou University from 2011 to 2018. Multiple logistic regression model was used to determine risk factors for TTP. Results Among 20 SLE with TTP patients, 16 were female and 4 were male. The median age at diagnosis was 47 (14-74) years old. Three cases of TTP were diagnosed during the treatment of SLE, 16 cases were diagnosed after the diagnosis of SLE, while 1 case was diagnosed before SLE. Logistic analysis showed that the independent risk factors for TTP included Systemiclupus erythematosus disease activity index (SLEDAI)>10, renal and CNS involvement (P<0.05). Conclusion Patients with SLE who have moderate or high disease activity, renal and Central nervous system (CNS) involvement significantly increases the risk of TTP.

Objective:To assess the value of amide proton transfer weighted (APTw) imaging in the evaluation of pH changes in infarct core (IC) and ischemic penumbra (IP) in subacute cerebral infarction.Methods:The data of twenty-three subacute cerebral infarction patients with unilateral steno-occlusive disease of the middle cerebral artery (subacute infarction group) from April to November 2019 in the First Affiliated Hospital of Dalian Medical University were prospectively analyzed. Fifteen healthy volunteers were enrolled in this study as the control group. All subjects underwent conventional MRI, DWI, 3D-pseudo continuous arterial spin labeling (3D-pCASL) and APTw sequences. Based on DWI images, relative cerebral blood flow (rCBF) and APTw images to determine the region of IC, blood flow penumbra [cerebral blood flow(CBF)-DWI mismatch area, IP CBF] and metabolic penumbra (APTw-DWI mismatched area, IP APT). 3D ROIs were used to semi-automatically measure the APTw signals and the volume of IC and IP CBF of the patients in subacute infarction group. The comparison of APTw signals between the infarct side and the contralateral side in the subacute infarction group, the comparison of bilateral APTw signals in the control group, and the comparison of APTw signals in the IC and IP CBF regions were performed by paired-sample t test or Wilcoxon signed-rank test. The paired-sample t test or Mann-Whitney U test was used to compare the APTw signals between the two groups. The Friedman test was applied to compare the difference of volumes among IP CBF1.5, IP CBF2.5 and IP APT . Results:There was no significant difference of the APTw signals among the IC, the contralateral side in the subacute infarction group and the control group ( P>0.05). The APTw signals of IP CBF and IC of the infarction group were statistically different ( P<0.05). Compared with the contralateral side of IP CBF1.5 (3.7±1.7, -1.84±1.48, 5.57±2.75), the APTwmax (3.07±1.41, t=-3.012, P=0.006), APTw min [-1.30 (-1.74, -0.57), Z=-2.099, P=0.036], and APTwmax-min(4.51±2.58, t=-3.273, P=0.003) signals in the IP CBF1.5 were decreased ( P<0.05). Compared with the contralateral side of IP CBF2.5 [-1.53 (-2.80, -0.91), 5.31±2.61], the APTw min [-1.08 (-1.60, -0.49), Z=-2.616, P=0.009] and APTwmax-min (4.41±2.72, t=-3.228, P=0.004) signals in the IP CBF2.5 were decreased. The volumes of IP CBF1.5 [107.51(50.08, 138.61)mm 3], IP APT [99.00 (53.27, 121.335) mm 3] and IP CBF2.5 [89.91 (51.53, 139.87) mm 3] were successively reduced (χ2=7.913, P=0.019), and the volume of IP CBF2.5 was significantly smaller than that of IP CBF1.5 ( P=0.037). Conclusion:The acid-base metabolism in the IC of subacute cerebral infarction is not obvious, but the blood flow penumbra has local acid-base metabolism imbalance, and the range of metabolic penumbra coincides with the blood flow penumbra.

Objective:To assess the performance of liver and spleen stiffness measured by MR elastography (MRE) and their combined model in diagnosing liver fibrosis.Methods:From November 2018 to November 2019, 104 patients with chronic liver disease were prospectively enrolled in Beijing Friendship Hospital, all patients underwent MRE scans. Liver and spleen stiffness were measured from MRE elastograms. Liver biopsy was used to identify fibrosis stage (F0—F4). The differences among different fibrosis stages were analyzed by one-way ANOVA or independent samples t test. The Spearman rank correlation analysis was used to evaluate the correlation with fibrosis stages. Liver and spleen stiffness combined model was established by logistic regression. The ROC curve was used to evaluate the performance of the liver, spleen stiffness and combined model in staging fibrosis (≥F1), significant fibrosis (≥F2), advanced fibrosis (≥F3), and cirrhosis (F4).The area under the ROC curve(AUC) was compared using Delong test. Results:The liver and spleen stiffness both showed significant differences among the 5 fibrosis stages ( F=64.058, 32.890, both P<0.001). The liver and spleen stiffness were positively associated with fibrosis stage ( r s=0.89, 0.69, both P<0.001). The AUC of liver stiffness in staging ≥F1, ≥F2, ≥F3 were 0. 91, 0.97, 0.93, respectively. The corresponding AUCs of the spleen stiffness were 0.81, 0.82, 0.85, respectively, which were statistically lower than those of liver stiffness ( Z=2.283, 4.085, 2.314, P=0.022,<0.001, 0.021). In diagnosing F4, the AUCs of liver and spleen stiffness were both 0.95. The AUCs of the liver and spleen combined model were 0.92, 0.97, 0.93, 0.96 in diagnosing ≥F1, ≥F2, ≥F3 and F4, with no significantly differences from liver stiffness (all P>0.05). Conclusions:The liver stiffness measured with MRE have better diagnostic performance than spleen stiffness in staging fibrosis. Parameters combined model slightly improves diagnostic value but without significant difference with liver stiffness in staging early fibrosis. Spleen stiffness evaluation is feasible in detecting cirrhosis.
