The optimization of imaging reconnaissance constellation is of great significance for reconnaissance timeliness. At present, evolutionary algorithms based on Pareto are often used in the optimization of reconnaissance constellation. In order to solve the problems of insufficient selection pressure and poor diversity of such algorithms in the optimization of reconnaissance constellation whose objective function dimension is greater than three, the improved particle swarm optimization algorithm based on relative entropy of fuzzy sets(IFREM-PSO) is proposed. The algorithm improves the adaptive inertial weight strategy and enhances the convergence speed and accuracy. The introduction of variation strategy is conducive to jumping out of the local optimal solution. Improve external archive maintenance policy to enhance diversity. Based on the design and optimization of regional target-oriented visible light reconnaissance constellation, MOPSO, FREM-PSO and the IFREM-PSO are used to optimize the reconnaissance constellation. The experimental results show that the algorithm based on fuzzy relative entropy has a better performance in this problem, and compared with FREM-PSO algorithm, IFREM-PSO algorithm has a significant improvement in convergence speed, and a better performance in convergence effect and diversity.

Objective To investigate the electrophysiological character,seizure symptomatology and seizure transmission mode of cingulate gyrus epilepsy. Methods 10 patients with cingulate gyrus epilepsy confirmed by stereoelectroencephalography(SEEG)and had good postoperative outcomes in Department of Neurosurgery,the Second Hospital of Lanzhou University from March 2015 to June 2022 were analyzed retrospectively,and their electrophysiological character,seizure symptoms and corresponding propagation patterns were analyzed separately. Results Scalp electroencephalography in 4 cases of anterior cingulate gyrus epilepsy and 2 of middle cingulate gyrus epilepsy could provide valuable information for lateral localization of epileptic foci. The scalp electroencephalogram of 4 cases of posterior cingulate gyrus epilepsy was difficult to provide meaningful lateral localization value and was often misleading. Therefore,10 patients underwent SEEG evaluation,which could clearly identify the epileptic focus. Anterior cingulate gyrus epilepsy was mainly characterized by complex motor symptoms with fear. Middle cingulate gyrus epilepsy manifested as goal-directed motor behavior and rigidity posture. Epilepsy in the posterior cingulate gyrus was a pseudo temporal lobe symptom. The anterior cingulate gyrus mainly involved emotional networks. The middle cingulate gyrus mainly involved the pre-motor area and auxiliary motor area in the motor network. The posterior cingulate gyrus mainly spread to the temporal lobe and inferior parietal lobules,causing temporal lobe symptoms. Conclusions Although cingulate epilepsy has variable clinical symptoms and is difficult to locate and diagnose,there is still a certain pattern to follow. Familiarity with functional connectivity of different subdivisions of the cingulate gyrus is a prerequisite for the correct diagnosis and location of epilepsy in this region. In the diagnosis of cingulate epilepsy,SEEG plays an important role in its location. [ABSTRACT FROM AUTHOR]

Objective To explore the use of digital technology to intervene in the precise force stimuli for labial high positioned maxillary canines before the orthodontic treatment so as to improve alveolar crest absorption. Methods 54 maxillary labial low canine teeth from 43 adult orthodontic patients were included and divided into an intervention group and a non-intervention group. The distance between cemento-enamel bone junction and alveolar crest (CEJ-AC) before and after the treatment and other relevant data were statistically analyzed. Results 1. There was no statistical difference of CEJ-AC between the intervention group and the non-intervention group before the treatment; After the treatment, the CEJ-AC in the intervention group was lower than that before the treatment (P < 0.05), and there was no statistical difference of the CEJ-AC in the non-intervention group. 2. Before and after the treatment, there was no statistical difference in the changes of CEJ-AC in patients with thin gingival biotype, but decreased in patients with thick gingival biotype in the intervention group (P < 0.05). 3. The CEJ-AC decreased after the fixed orthodontic therapy intervention group (P < 0.05), and the difference between CEJ-AC before and after the treatment was greater than that in the conventional correction group (P < 0.05), while the reduction value of CEJ-AC of the invisible intervention group after the orthodontic therapy was greater than that in the conventional correction group (P < 0.05). Conclusion Pre-treatment intervention appliance with digitally designed for labial high maxillary canines can improve alveolar crest absorption after the orthodontic treatment in patients with thick gingival biotype. However, there are no significant effects on thin gingival biotype. Interventions prior to fixed or invisible correction are both effective. [ABSTRACT FROM AUTHOR]

BACKGROUND: Stem cell therapy has emerged as a novel treatment for chronic temporal lobe epilepsy that has been widely used in various animal models of epilepsy. However, there is yet no consensus in the therapeutic effect in existing experimental studies. OBJECTIVE: To systemically evaluate the therapeutic efficacy of stem cell therapy in animal models of chronic temporal lobe epilepsy, providing experimental evidence and new ideas for further clinical trials. METHODS: A systematic search of CNKI, WanFang, PubMed, Embase and Web of Science was performed for animal studies related to stem cell therapy for chronic temporal lobe epilepsy published from inception to May 2018. Two reviewers independently extracted data, assessed methodological quality and evaluated evidence quality by using CERQual tool. RESULTS AND CONCLUSION: Eight animal studies were eligible for inclusion, including 284 animals suffering chronic temporal lobe epilepsy. Between-study heterogeneity was substantial, so a qualitative description was performed. Stem cell therapy has some improvement in the seizure frequency and duration of chronic temporal lobe epilepsy in animals, which can promote the recovery from epilepsy in most animals. Other outcomes include memory and learning, stem cell migration, differentiation and integration. The exact efficacy of stem cells cannot be determined due to the lack of rigor, characterization, and evidence quality. We therefore do not have absolute confidence to recommend the clinical use of stem cell therapy for chronic temporal lobe epilepsy. Thus, it is necessary to conduct high-quality preclinical studies to further evaluate the efficacy of stem cell transplantation for chronic temporal lobe epilepsy and its clinical conversion risk before implementation of clinical trials.

Agricultural efficient water saving technology develops very fast in Xinjiang, hut as the main water supply source, the fact that sediment concentration of surface water is high affecting the promotion of the technology. So, it's necessary to research the bed cleaning device which can treat sediment effectively and meet the requirements of drip irrigation and the investment is relatively lower. The water drip gravity sinking sand filter tank has better solved the above problems. In this paper, we took the gravity desilting and filter basin of river water drip irrigation as the research object and studied the effects of water-sediment separation by the physical experiment, which the settling basin was 25 m long and the lateral overflow weir is 5 m, 3 m and 2 m long. The results show that the total processing efficiency of sediment can reach more than 55% under the working condition of the structure and the optimal side weir length is 3 m. 'Hie imported maximum sediment concentration is about 1.5 kg/m3 which meet the pool water quality standard. [ABSTRACT FROM AUTHOR]

输血相关性坏死性小肠结肠炎（TANEC）是坏死性小肠结肠炎的一种亚型，多于新生儿输血后早期（48 h内）发病，早产儿、低出生体重儿（ LBWI）发生率更高。 TANEC的发病机制尚未完全明确。早产儿、LBWI肠道输氧功能差，肠道血流自主调节不成熟，输血后肠道血流动力学改变，造成肠道缺血，导致TANEC；组织兼容性抗原（ HLA）相关免疫反应造成的肠道损伤也与TANEC的发生有关。早产儿延迟结扎脐带、减少医源性失血、明确早产儿、LBWI输血指征、母乳喂养、输血前及输血过程中适当禁食可能有助于降低TANEC的发生率。 [ABSTRACT FROM AUTHOR]
