Motor imagery EEG classification and recognition based on differential entropy and convolutional neural network / 中国医学物理学杂志

To address the problem of low accuracy in multi-classification recognition of motor imagery electroencephalogram(EEG)signals,a recognition method is proposed based on differential entropy and convolutional neural network for 4-class classification of motor imagery.EEG signals are extracted into 4 frequency bands(Alpha,Beta,Theta,and Gamma)through the filter,followed by the computation of differential entropy for each frequency band.According to the spatial characteristics of brain electrodes,the data structure is reconstructed into three-dimensional EEG signal feature cube which is input into convolutional neural network for 4-class classification.The method achieves an accuracy of 95.88%on the BCI Competition IV-2a public dataset.Additionally,a 4-class classification motor imagery dataset is established in the laboratory for the same processing,and an accuracy of 94.50%is obtained.The test results demonstrate that the proposed method exhibits superior recognition performance.

Effect of platelet-rich plasma on blood coagulation indexes after hip preserving surgery for osteonecrosis of the femoral head / 中国组织工程研究

BACKGROUND: It was found that platelet-rich plasma injection can change the coagulation function of patients with osteonecrosis of the femoral head. OBJECTIVE: To investigate the effect of platelet-rich plasma injection on coagulation parameters in patients with osteonecrosis of the femoral head after hip preserving surgery, and to evaluate the risk factors of vascular embolism after surgery. METHODS: Totally 75 cases of osteonecrosis of the femoral head treated by drilling and decompression of the femoral head, removing the dead bone in the femoral head and supporting with fibula allograft were selected in the First Affiliated Hospital of Guangzhou University of Chinese Medicine from December 2016 to September 2018. According to whether platelet-rich plasma injection was used during the operation, the patients were divided into two groups. The platelet-rich plasma group contained 42 cases (42 hips). The control group (33 cases, 35 hips) did not use platelet-rich plasma. The other treatments in the two groups were the same. The changes of blood coagulation indexes before and after operation were continuously observed in the two groups. RESULTS AND CONCLUSION: (1) Patients in both groups were followed up for 3 months. (2) Levels of fibrinogen and D-dimer were significantly increased in both groups. However, levels of fibrinogen and D-dimer in one week after operation in the platelet-rich plasma group were 52.5% and 47.0% higher than those in the control group, indicating platelet-rich plasma led to hypercoagulability and a possible high risk of vascular embolism. (3) There were significant differences in prothrombin time, activated partial thromboplastin time and international standardized ratio, but there was no significant clinical significance in both groups. (4) The use of platelet-rich plasma had no effect on platelet level or C-reactive protein.

A study on the effects of four major neonatal diseases on thyroid function / 中国新生儿科杂志

Objective To study the effects of preterm birth, infection, pathological jaundice and asphyxia on neonatal thyroid function. Methods From April 2012 to April 2014,neonates within 7 days after birth admitted to the neonatal department of our hospital were recruited. The neonates with one or more of the 4 aforementioned conditions were assigned to the observation group; the full-term newborns without any diseases to the control group. 2 ml of venous blood from each patient was collected 5-7 days after birth to determine the levels of serum free iodine thyroid original glycine ( FT3 ) , free thyroxine ( FT4 ) and thyroid stimulating hormone ( TSH ) . The thyroid function of newborns in the observation group were re-examined after recovery, and compared among different groups and conditions. Results A total of 220 newborns were recruited in the observation group and 34 in the control group. FT3 in the observation group was significantly lower than the control group ( P＜0. 05 ) . As for FT4 and TSH, no statistically significant differences existed between the two groups ( p＞0. 05 ) . FT3 and FT4 in neonates with severe infection were significantly lower than mild infection ( P＜0. 05 ) . FT3 in the preterm group with gestational age ( GA ) ≤32 weeks was significantly lower than GA＞32 weeks, and FT3 in the jaundice group, serum bilirubin level ≥ 342 mol/L group significantly lower than ＜342 mol/L group (P＜0. 05) . In the observation group, the re-examined FT3 concentration was significantly higher (P＜0. 05) than the result tested 5-7 days after birth while FT4 and TSH didn′t show significant differences. And no significant differences existed between the observation group and the control group in re-examined thyroid functions ( P＞0. 05 ) . The multivariate analysis showed that GA, pathological jaundice, infection and asphyxia were associated with FT3 concentration 5-7 days after birth (P＜0. 05), while the delivery method and gender not (P＞0. 05). Conclusions The main effect of preterm birth, infection, pathological jaundice and asphyxia on thyroid function was to decrease FT3 temporarily. Severe infection might decrease FT4 temporarily. However, the thyroid function would return to normal with recovery.
