BACKGROUND：Studies have demonstrated that brain-derived neurotrophic factor （BDNF） has a dual effect on epilepsy. However, the relationship between epilepsy-induced brain injury and BDNF remains poorly ***：According to ultrastructural and molecular parameters, to detect the degree of neuronal injury and BDNF expression changes at different brain regions and different kindling times to determine the effects of BDNF on epilepsy-induced brain ***, TIME AND SETTING：A randomized, controlled, animal experiment based on neuropathology and molecular biology was performed at the Department of Physiology and Department of Pathology, Basic Medical College of Jilin University in ***：UltraSensitiveTM SP kit for immunohistochemistry （Fuzhou Maxim Biotechnology, China）, BDNF antibody （concentrated type, Wuhan Boster Biological Technology, China）, JEM-1000SX transmission electron microscopy （JEOL, Japan）, and BH-2 light microscope （Olympus, Japan） were used in the present ***：Wistar rats were randomly assigned to control （n = 6）, sham-surgery （n = 6）, and model （n = 60） groups. The control group rats were not treated; an electrode was embedded into the amygdala in rats from the sham-surgery and model groups; an amygdala kindling epilepsy model was established in the model *** OUTCOME MEASURES：Pathological changes in the temporal lobe and hippocampus were observed by light and electron microscopy at 1, 3, 7, 14, and 21 days following kindling, and BDNF expression in the various brain regions was determined by ***：In the model group, temporal lobe cortical and hippocampal neurons were swollen and the nuclei were laterally deviated. There were also some apoptotic neurons 3 days after kindling. The nucleoli disappeared and the nuclei appeared broken or lysed, as well as slight microglia hyperplasia, at 7 days. Electron microscopic observation displayed chromatin aggregation in the nuclei and slight mitochon

Adhesive ileus in pregnant women

作者： li-na cui Zhong-tai li Affiliated Hospital of Yanbian University Yanbian 133000JilinChina

A female patient was of the pregnancy for less than 24 weeks and suffered from adhesive ileus. The conservative treatment with acupuncture was selected to keep the fetus alive. A single-used filiform needle,0.30 mm x 40 mm was used. Zúsānlǐ(足三里ST 36), Shàngjùxū(上巨虚 ST 37), Tàichōng(太冲 LR 3) and Zhigōu(支沟TE 6) were selected bilaterally. At each acupoint, the needle was inserted rapidly and manipulated with the twisting, lifting and thrusting techniques to induce mild stimulation. Additionally, the electric stimulation was added at ST 36 and ST 37, with the continuous wave, 60 times per minute in frequency. The needles were retained for 25 min in each treatment. During the hospital stay, the treatment was given once every day and the condition of the disorder was observed carefully. The patient was discharged from the hospital in her 30 weeks of pregnancy. Afterward, acupuncture treatment was given once every one or two days in clinic till the weeks 34 of pregnancy. After acupuncture treatment,the conditions of abdominal distention, enteric flatus and defecation were relieved sustainably through to the cesarean section in weeks 34 of pregnancy. Both the patient and her infant were healthy when discharged. It was proved that acupuncture therapy was applicable and effective in the pregnant patient with ileus.

Edge Device Fault Probability Based Intelligent Calculations for Fault Probability of Smart Systems

Tsinghua Science and Technology 2024年第4期29卷 1023-1036页

作者： Shasha li Tiejun cui Wattana Viriyasitavat School of Environmental and Chemical Engineering Shenyang Ligong UniversityShenyang 110159China Chulalongkorn Business School Faculty of Commerce and AccountancyChulalongkorn UniversityBangkok 10900Thailand

In a smart system, the faults of edge devices directly impact the system’s overall fault. Further, complexity arises when different edge devices provide varying fault data. To study the Smart System Fault Evolution Process (SSFEP) under different fault data conditions, an intelligent method for determining the Smart System Fault Probability (SSFP) is proposed. The data types provided by edge devices include the following: (1) only known edge device fault probability;(2) known Edge Device Fault Probability Distribution (EDFPD);(3) known edge device fault number and EDFPD;(4) known factor state of the edge device fault and EDFPD. Moreover, decision methods are proposed for each data case. Transfer Probability (TP) is divided into Continuity Transfer Probability (CTP) and Filterability Transfer Probability (FTP). CTP asserts that a Cause Event (CE) must lead to a Result Event (RE), while FTP requires CF probability to exceed a threshold before RF occurs. These probabilities are used to calculate SSFP. This paper introduces a decision method using the information diffusion principle for low-data SSFP determination, along with an improved method. The method is based on space fault network theory, abstracting SSFEP into a System Fault Evolution Process (SFEP) for research purposes.

nano-effect enhanced cooperative luminescence of Yb^(3+) clusters in bulk materials

Journal of Rare Earths 2024年第3期42卷 473-478,I0002页

作者： Daguang li Jiahao cui Yanhui Dong Hao cui Dan Zhao Weiping Qin State Key Laboratory on Integrated Optoelectronics College of Electronic Science and EngineeringJilin UniversityChangchun130012China

In order to improve the multi-ion cooperative transition, we proposed and exploited a novel nanoscale effect, namely the nanoshell effect in bulk materials. Based on the effect, an optimal material structure was designed by coating the surfaces of Ca F_(2):Yb^(3+)micron size particles with ZrO_(2). An about 2 times higher intensity of cooperative luminescence is observed upon laser excitation at 980 nm. Dynamical analysis exhibits that the novel effect plays a key role in improving the performance of cooperative transitions. Our results also suggest that the nanoshell effect in bulk materials is likely to be significant in some special cases, which have not been reported yet in the literature.
