Objective To analyze the progress and current status of ethical research in the field of organ donation and transplantation in China by bibliometric analysis. Methods Literature review was conducted from CNKI between January 2000 to December 2023. The number of published articles, the cooperation network of core authors, the cooperation network of publication institutions, the co-occurrence of keywords, the emergent keywords and the clustering of keywords were analyzed by CiteSpace 6.2.6. Results A total of 399 valid articles were obtained. The three peaks in the trend of published articles were affected by current policy events and the development of transplantation technology. From 2000 to 2014, the number of published articles showed an upward trend. At this stage, these studies focused on ethical speculation in the field of organ donation and transplantation. From 2015 to 2023, the number of published articles showed a fluctuating trend. During this stage, these researches highlighted the work system of donation and transplantation and ethical issues in medical practice. Organ donation and ethical review after citizen death became the research frontiers. The co-occurrence knowledge map of authors reflected that the authors mainly served as single nodes, lacking of communication among authors. Twenty-five core authors were identified. Diverse publication institutions were searched including medical departments from colleges and universities, ethics research institutions, organ transplantation departments from hospitals, ethics committees from hospitals and human Organ Procurement Organization (OPO), etc. The First Hospital of Kunming published the largest number of articles. A total of 252 keywords and 13 emergent words were extracted. The keywords with the highest degree of emergency consisted of brain death, organ donation, legislation and ethical review. A total of 14 keyword clusters were generated, including organ transplantation, organ donation, organ donation after citizen’s death, ethics, ethical review and medical staff. Conclusions The cooperation among authors and institutions is insufficient in the field of organ donation and transplantation ethics. Multi-center research and cooperation among authors should be strengthened. Extensive efforts should be made to strengthen the exploration and empirical research of ethical issues based on current work system and medical practice, aiming to provide ethical basis and defense for the reform and practice of organ donation and transplantation.

Knowledge Tracing (KT) is a key task in educational data mining, aiming at modeling students􀆳 changing knowledge states over time to infer students􀆳 proficiency on concepts. However, most of existing knowledge tracing methods ignore the reliability and high-dimensional sparsity of the student-concept space based on the student-exercise-concept relationship, and do not combine the student􀆳s response to the exercise to generate a reliable response representation. To address the above issues, a reliable response representation enhanced knowledge tracing method is proposed. Specifically, firstly, the student-exercise space is divided into fine-grained student-exercise spaces based on the student's response records, and different student-concept spaces are obtained based on the exerciseconcept space; secondly, the reliability of the student-concept space is obtained from both the relative reliability and absolute reliability of the student-concept space, and a reliable and low-dimensional student-concept space is obtained using dimensionality reduction methods; thirdly, the reliable response representation of the exercise is obtained by combining the student􀆳s response to the exercise and the exercise representation method under two response conditions; finally, the student􀆳s knowledge state at different timesteps is evaluated using a long short-term memory network and the obtained reliable response representation. Experimental results on four real datasets demonstrate the effectiveness and interpretability of the proposed method. [ABSTRACT FROM AUTHOR]

BACKGROUND: The treatment of cervical spondylosis with total disc replacement can retain the range of motion of the cervical lesion segment and can effectively improve the symptoms of cervical spondylosis with sympathetic symptoms. OBJECTIVE: To investigate the clinical efficacy of total disc replacement for cervical spondylosis with sympathetic symptoms. METHODS: Retrospective analysis was made on 56 patients with cervical spondylosis with obvious sympathetic symptoms such as dizziness and headache who were operated on from December 2018 to December 2021. The sagittal parameters of the cervical spine before, 3 months after surgery and at the last followup were observed and compared, including cervical sympathetic symptom score and Japanese Orthopaedic Association Scores, operation segment angle, C2- C7 Cobb angle, C2-C7 sagittal vertical axis and T1 slope. The correlation between the changes in sympathetic symptoms and Japanese Orthopaedic Association Scores before and after surgery and the changes in cervical sagittal parameters before and after surgery was analyzed. RESULTS AND CONCLUSION: (1) All patients showed improvement in sympathetic symptoms after surgery, and the sympathetic symptom scores and Japanese Orthopaedic Association Scores were significantly improved at 3 months and at the last follow-up compared with those before surgery (P < 0.05), but Japanese Orthopaedic Association Scores did not show significant differences at the last follow-up compared with those at 3 months after surgery (P > 0.05). (2) The cervical sagittal parameters increased at 3 months and at the last follow-up compared with those before surgery, but not at the last follow-up compared with those at 3 months after surgery (P > 0.05). (3) The pre- and post-operative change values of sympathetic symptom scores significantly correlated with the preand post-operative change values of operation segment angle and C2-7 Cobb angle (P < 0.05). (4) The results indicate that total disc replacement has a good effect in the treatment of cervical spondylosis with sympathetic symptoms, which is conducive to restoring the sagittal parameters of the cervical spine and alleviating the sympathetic symptoms of patients.

Objective: To investigate the epidemiological situation of hearing impairment in children aged 0～14 years in Suzhou, and to analyze the risk factors of the disease. Methods: Using the method of multi-stage and random sampling,1478 samples were selected from 46 streets and 51 towns in the region from January 2020 to January 2022. On-site investigation was carried out using the 《WHO Survey Plan on Ear Diseases and Hearing Impairment》. Pure tone audiometry was performed on children aged 0～14 years with AA222 screening audiometer. Hearing threshold greater than or equal to 26dB indicated that there was hearing impairment. The epidemiology of hearing impairment in children aged 0~14 years in Suzhou was investigated, and the risk factors of hearing impairment were analyzed. Results: 1478 subjects aged 0~14 years were included, 1459 of whom had complete data, with a recovery rate of 98.71%. All the subjects were divided into hearing impairment group (n=42) and non-hearing impairment group (n=1417) according to the occurrence of hearing impairment. The incidence of hearing impairment was 2.88%. Among them, the prevalence rate of male was higher than that of female, the prevalence rate of 8~14 years was higher than that of 0~7 years, and the prevalence rate of town was higher than that of countryside. The incidence of hearing impairment was related to the previous use of ototoxic drugs, family history of positive deafness, maternal perinatal infection, hyperbilirubinemia, neonatal asphyxia, maternal disease during pregnancy, adverse living habits during maternal pregnancy, adverse social environmental factors during maternal pregnancy, gender and age (P<0.05), but not related to head and neck deformities, bacterial meningitis, previous disease history in infancy and place of residence (P>0.05). Multivariate Logistic regression analysis showed that age 8~14 years, previous use of ototoxic drugs, had maternal perinatal infection, had hyperbilirubinemia, had maternal disease during pregnancy, had adverse living habits during maternal pregnancy, had adverse social environmental factors during maternal pregnancy, had family history of positive deafness, and had neonatal asphyxia were risk factors for hearing impairment (P<0.05). Conclusion: The incidence of hearing impairment in children aged 0～14 years in Suzhou is 2.88%, most of whom were aged 8~14 years. The incidence of hearing impairment is affected by many factors, such as the previous use of ototoxic drugs, maternal perinatal infection, hyperbilirubinemia, maternal disease during pregnancy, adverse living habits during maternal pregnancy, adverse social environmental factors during maternal pregnancy, family history of positive deafness, neonatal asphyxia and so on.

Objective To investigate the effect of curcumin (Cur) regulating N-methyl-D-aspartate receptor (NMDAR)/calcium ion (Ca2+ )/calmodulin dependent protein kinase Ⅱ (CaMKⅡ) signaling pathway on isoflurane (ISO) - induced postoperative cognitive dysfunction (POCD) in young mice. Methods Seventy-two C57BL/6J mice were separated into the control group, the ISO group, the low-dose Cur group (Cur-L group, 50 mg/kg), the medium-dose Cur group (Cur-M group, 100 mg/kg), the high-dose Cur group (Cur-H group, 200 mg/kg) and the Cur-H+NMDA (NMDAR activator) group (200 mg/kg+8 mg/kg), with 12 animals in each group. After 30 min of corresponding drug treatment, the mice in the control group inhaled a mixed gas containing 30% oxygen and air for 2 hours, and mice in the other groups inhaled 2% ISO for 2 hours, once a day for 14 days. Twenty-four hours after the last treatment, Morris water maze test was used to detect the learning and spatial memory abilities of mice. HE staining was used to detect the pathological changes in hippocampal CA1 area. Immunofluorescence staining was used to detect the positive expression of neuron specific nucleoprotein (NeuN) in hippocampus CA1 region of mice. TUNEL staining was used to detect neuronal apoptosis. Enzyme linked immunosorbent assay was used to detect levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in hippocampal CA1 tissue. Western blot assay was used to detect NMDAR1 and CaMK Ⅱ protein expression in mouse hippocampal CA1 tissue. Intracellular Ca2+ concentration in hippocampal CA1 region was detected by fluorescence probe. Results Compared with the control group, the pathological damage of hippocampal CA1 region of mice was severe in the ISO group, and the escape latency was prolonged. The apoptosis rate of neural cells, levels of IL-1β and TNF-α, expression levels of NMDAR1 and CaMKⅡ protein, and the concentration of Ca2+ in hippocampal CA1 region were increased (P＜0.05). Times of crossing platform and the number of NeuN positive cells were decreased in the ISO group (P＜0.05). Compared with the ISO group, pathological damages of hippocampal CA1 region of mice were alleviated in the Cur-L group, the Cur-M group and the CurH group, the escape latency was shortened, and the apoptosis rate of neural cells, levels of IL-1β and TNF-α, expression levels of NMDAR1 and CaMKⅡ protein, and the concentration of Ca2+ in hippocampal CA1 region were decreased (P＜ 0.05). Times of crossing platform and the number of NeuN positive cells were increased (P＜0.05), which was dosedependent. NMDA attenuated the improvement effect of high-dose Cur on ISO induced POCD in mice (P＜0.05). Conclusion Curcumin may improve ISO-induced POCD in mice by inhibiting NMDAR/Ca2+ /CaMKⅡ signaling pathway [ABSTRACT FROM AUTHOR]

A single- factor design was used to investigate the effects of dietary casein phosphopeptide (CPP) on calcium metabolism of laying hens during late laying period. A total of 800 Hyline brown laying hens aged 58 weeks were randomly divided into five groups. The hens in the control group were fed a basal diet (T1 group). The experimental groups were fed the basal diets supplemented with 0.5 (T2 group), 1.0 (T3 group), 1.5 (T4 group), and 2.0 (T5 group) g/kg CPP, respectively. The results showed as follows: compared with the control group, the qualified rates of eggs in groups T2, T3, T4 and T5 were significantly increased (P<0.05); the tibia calcium content and tibia strength in T3 group were increased, while the serum alkaline phosphatase activity in T2 and T3 groups was significantly decreased (P<0.05). In duodenum, the carbonic anhydrase activity in T2 group was increased (P<0.05), the gene relative expressions of calcium binding protein and calcium pump in T4 group were significantly up-regulated (P<0.05), and the gene relative expressions of sodium- calcium exchange bodies in T3 and T5 groups were significantly up- regulated (P<0.05). The contents of calcium- binding protein in egg⁃ shell gland of T2 and T3 groups were increased (P<0.05). The relative gene expression level of alkaline phosphatase in experimental (T2, T3, T4, T5) group was up-regulated (P<0.05), while that of carbonic anhydrase was significantly down-regulated (P<0.05). In conclusion, dietary CPP can improve egg qualification rate and related enzyme activities in intestinal tract and eggshell gland of laying hens, and promote the serum calcium content and tibia strength. The T2 and T3 groups supplemented with 0.5 to 1.0 g/kg CPP had the best effect. [ABSTRACT FROM AUTHOR]

As a network analysis task that can capture user’s personalized information, community search aims at mining the community of query nodes that can satisfy the cohesion requirement. Most of the existing community search methods can only locate a single-scale community where query nodes are located. A Multi-Scale Community Search method based on Spectral Wavelet (MSCS＿SW) is proposed, which can mine the multi-scale community of query nodes by using spectral wavelet and local modularity. Specifically, firstly, the modularity matrix and the Laplacian are constructed, and decomposed to obtain the relevant eigenvectors. Secondly, based on the spectral theory and the graph wavelet, the scale-dependent local modularity is designed. Thirdly, based on the normalized Laplacian Matrix and the feature space of local modularity, a linear programming problem is designed to solve the sparse indicator vectors related to query at a given scale. Finally, the community boundary truncation strategy is used to add nodes to maximize the local modularity. Experimental results on synthetic network and real-world network datasets demonstrate the efficiency and effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

Taking 13 cities in Beijing, Tianjin and Hebei as the research objects, this paper constructed the urban smart development index system from three aspects: smart space construction, smart element allocation and smart welfare performance, measured the urban smart development level in Beijing, Tianjin and Hebei from 2008 to 2018, and used ArcGIS software to realize the temporal and spatial measurement performance of smart development level. The obstacle degree model was used to reveal the criterion-level factors that hinder the smart development of Beijing, Tianjin and Hebei cities. The main conclusions are as follows: (1) The smart development level in Beijing, Tianjin and Hebei is low, the research period shows a weak fluctuation and downward trend, and there is room for improvement. (2) From the spatial difference of smart development level, the double core trend with Beijing and Tianjin as the high level is obvious, showing a downward trend from the center to the surrounding. (3) From the overall barrier performance of study area, smart welfare performance accounts for the largest proportion, smart space construction takes the second place, and smart factor allocation is the lowest. (4) The obstacles to smart development in different cities vary. The obstacles in Beijing and Tianjin are mainly focused on smart welfare performance. As the main core area to undertake Beijing's noncapital functions, smart space construction and smart element allocation are the obstacles in most cities. [ABSTRACT FROM AUTHOR]
