The Chinese version of the test of everyday attention can be used to diagnose attention deficits after brain injury / 中华物理医学与康复杂志

Objective:To explore the value of the Chinese version of the test of everyday attention (TEA) for diagnosing attention deficit after brain injury, and to determine the best cut-off value for each subtest.Methods:A total of 117 healthy adults and 33 brain-injured patients were evaluated using the TEA (Chinese version). The original scores of each sub-test were obtained and statistically compared between the control group and the brain injury group. Receiver operating characteristics (ROC) curves were used to determine the optimal cutoff values in each subtest for diagnosing attention deficits.Results:Significant differences were found between the two groups. Except for the elevator counting test, the area under the ROC curves of all the other subtests (Map Search, Elevator Counting with Distraction, Visual Elevator, Elevator Counting with Reversal, Telephone Search, Telephone Search while Counting and lottery) were between 0.795 and 0.955. The average sensitivities were in the range 74.1-97.0% and the specificities were 58.8% to 94.1%. Maximum Youden indices were used to determine optimal diagnostic cut-off values for each subtest.Conclusions:The TEA (Chinese version) has good clinical applicability. It can be used to diagnose and differentiate different types of attention deficits.

Value of texture analysis in evaluating liver cancer recurrence after transarterial chemoembolization / 中华肝脏病杂志

Objective@#To investigate the feasibility of contrast-enhanced computer tomography (CT) texture analysis in predicting early recurrence after transarterial chemoembolization (TACE) in patients with liver cancer.@*Methods@#A retrospective analysis was performed for 47 patients with liver cancer confirmed by liver biopsy and digital subtraction angiography who underwent upper abdominal contrast-enhanced CT scan before TACE, and according to the presence or absence of focal recurrence within half a year, these patients were divided into early recurrence (ER) group and non-early recurrence (NER) group. The texture analysis was used to delineate tumor boundary layer by layer on the axial contrast-enhanced CT image before liver cancer surgery, and related parameters of tumor heterogeneity, including entropy, mean, non-uniformity, skewness, and kurtosis, were obtained. The independent samples t-test was used for comparison of texture parameters between the two groups. The receiver operating characteristic (ROC) curve was used for the analysis of entropy, mean, and non-uniformity, and the area under the ROC curve (ROC), optical cut-off value, sensitivity, and specificity were calculated to evaluate the efficiency of texture analysis in predicting early focal recurrence after TACE.@*Results@#There were 20 patients in the ER group and 27 in the NER group. The ER group had a maximum major axis length of 88.2±36.3 mm and a maximum minor axis length of 41.4±21.4 mm, and the NER group had a maximum major axis length of 66.9±30.2 mm and a maximum minor axis length of 29.3±19.8 mm; the ER group had significantly higher maximum major and minor axis lengths than the NER group (t = 4.89 and 4.62, P < 0.001). The ER group had significantly higher entropy and non-uniformity values than the NER group, and there were no significant differences in skewness and kurtosis between the two groups. Entropy, non-uniformity, and mean had high efficiency in predicting early recurrence after TACE, and the optimal cut-off value of entropy was 4.135.@*Conclusion@#Volumetric texture analysis of contrast-enhanced CT images before liver cancer surgery has a high value in predicting early recurrence after TACE.

Study on protective effect of astragaloside Ⅳ in septic mice / 中国药理学通报

Aim To study the effect of astragaloside (AS-Ⅳ) in CLP-induced septic mice.Methods C57BL/6 mice were randomly divided into the sham group, CLP group and CLP+ AS-Ⅳ group.Two days before operation, AS-Ⅳ (10 mg·kg-1) solution was intragastrically administered into CLP +AS-Ⅳ group, and the other groups were treated with normal saline.A sepsis model was established by cecal ligation and puncture (CLP).Blood, peritoneal fluid and tissue organs were collected at 6 h and 24 h.Neutrophils of blood were purified by Percoll density gradient.Transwell was used to detect the chemotaxis function of neutrophils.The killing activity of neutrophils was detected by coculture with E.coli.Results The survival rate of AS-Ⅳ-pretreated septic mice significantly increased.The number of neutrophils in peritoneal fluid was enhanced markedly.The number of bacteria in the peritoneal fluid, blood and tissue organs such as liver, lung and kidney significantly decreased after AS-Ⅳ pretreatment.The chemotaxis and killing activity of neutrophils increased significantly in AS-Ⅳ-treated mice (P<0.05).Conclusion Astragaloside displays an immunoprotective effect in CLP-induced septic mice, which is related to the upregulation of CXCR2 expression on neutrophils and the increase of neutrophil antibacterial activity.

The value of heart-type fatty acid-binding protein for early detection of acute myocardial infarction / 中华老年医学杂志

Objective To evaluate the diagnostic value of H-FABP for early detection of acute myocardial infarction(AMI). Methods Serum H-FABP of 126 healthy individuals and 53 AMI patients were measured by self developed ELISA. MYO, cTnI and CK-MB, traditional biochemistry diagnostic markers were estimated at the same time. The dynamic movement of these myocardial indicators for AMI patients, and their diagnostic sensitivity and specificity in the earlier period of AMI onset was analyzed. Results The plasma concentration of H-FABP began to increase at (1.84?0.64) h after AMI onset, earlier than CK-MB and cTnI. The time-concentration dynamic curves of H-FABP was similar to that of MYO and moved to left in comparison with both CK-MB and cTnI. The sensitivity and specificity of H-FABP at 2 h after AMI were 76.47% and 80.41%, and 89.16% and 91.26% at 4 h, respectively;. Conclusions H-FABP is more sensitive and specific in the early diagnosis of AMI within 2 hours and at 4 hours after symptom onset. It is hoped that H-FABP become an important myocardial marker for both early diagnosis and elimination diagnosis of AMI.
