BACKGROUND: Atlantoaxial dislocation is often facilitated by interlaminar bone grafting. However, there are relatively few reports on the treatment of complex atlantoaxial dislocation with posterior atlantoaxial lateral mass interarticular release and fusion. OBJECTIVE: To explore the safety and effectiveness of atlantoaxial dislocation treated by simple posterior atlantoaxial lateral block interarticular release and fusion. METHODS: We retrospectively analyzed the clinical data of 30 patients with atlantoaxial dislocation who were treated from January 2017 to July 2021, all of whom suffered from reducible atlantoaxial dislocation. Posterior atlantoaxial lateral mass interarticular release and fusion were performed in all patients. During the surgery, patented instruments were used to release the atlantoaxial lateral mass joint, and posterior screw reduction and fixation were used with bone grafting in the lateral mass joint space. The postoperative follow-up period was 6 to 24 months, mean (13.0±5.4) months. During the follow-up period, cervical MRI was reviewed to observe the decompression of the upper cervical spine. X-ray films and CT scans were reviewed to observe the reduction of the upper cervical spine, as well as the internal fixation for looseness and breakage. CT scans were reviewed to assess interlateral block implant fusion. The Japanese Orthopaedic Association score was used to evaluate the improvement of spinal cord function. The neck disability index and the quality of life scale were used to assess the improvement of daily life function. The atlanto-anterior interspace and atlanto-planar spinal effective space were used to evaluate atlantoaxial repositioning and decompression. RESULTS AND CONCLUSION: (1) The surgery of 30 patients went smoothly, and no serious complications such as spinal nerve and vertebral artery injuries occurred during the operation. Postoperative review of cervical MRI showed that the spinal cord compression was lifted. X-ray film and CT showed that the atlanto-anterior gap was significantly reduced; the effective space of atlantoaxial spinal cord was significantly increased, and neurological dysfunctional symptoms were significantly reduced. (2) During the follow-up period, X-ray film and CT showed that the internal fixation was solid; no broken nails or rods occurred, and there was no recurrence of atlantoaxial dislocation. (3) The Japanese Orthopaedic Association scores, neck disability index, and quality of life scores were significantly improved at the last follow-up compared with the preoperative period (P < 0.05). The average improvement rate of Japanese Orthopaedic Association scores at the last follow-up was 73.1%. The average neck disability index was 8.80%. All of the patients had a continuous bone-scalp connection between atlantoaxial lateral block joints to achieve osseous fusion. (4) These findings indicate that the use of simple posterior atlantoaxial lateral block interarticular release and fusion for the treatment of atlantoaxial dislocation can significantly increase the fusion rate and shorten the fusion time.

Different from the current rolling bearing fault diagnosis which mainly focuses on the qualitative analysis stage, a quantitative fault diagnosis method for rolling bearings based on image classification is proposed. The overlapping sampling method is used to enhance the one‑dimensional time series data, and then the Markov transition field (MTF) method is used to convert the one‑dimensional time series data into two‑dimensional images, which provide two‑dimensional image samples for inputting into the neural network model and retain the time‑domain information. The ResNeXt and ResNeSt modified residual networks with fine‑tuning processing based on transfer learning are built and trained to classify fault images and realize fault diagnosis. The confusion matrix method and t‑distributed stochastic neighbor embedding (t‑SNE) visualization method are used to carry out experiments. The results show that the proposed method for rolling bearing fault diagnosis can realize the quantitative diagnosis of multi‑working condition rolling bearing fault, and has higher diagnosis accuracy and faster training speed.

Objective To understand the current situation of nosocomial infection management in primary medical institutions in Guizhou Province, and to provide reference for standardizing the professional development of nosocomial infection management in primary medical institutions. Methods By using the method of electronic questionnaire survey, the management of nosocomial infection in primary medical institutions in Guizhou Province from April 1 to 30, 2022 was investigated, and 611 valid questionnaires were retrieved. Results Among the 611 primary health care institutions, 401 medical institutions set up nosocomial infection committees, 149 medical institutions set up independent nosocomial infection management departments, 321 medical institutions were equipped with full-time staff for nosocomial infection management, and 573 medical institutions were equipped with part-time staff for nosocomial infection management. In total, 321 primary health care institutions were equipped with 334 full-time staff for nosocomial infection management. The average age was (35.19±8.57) years old, the gender was mainly female, the major was nursing, and the degree was bachelor degree or below. The management of nosocomial infection in different types of primary health care institutions was compared and analyzed, and there were differences in age, professional background, educational background, and working years of nosocomial infection department (P < 0.05). The focus of the full-time staff of nosocomial infection management was the issue of salary. Conclusion The construction of the organizational structure of nosocomial infection management in private grass -roots medical institutions in Guizhou Province needs to be strengthened, and some full-time staff are engaged in nosocomial infection management for a short time, so they need to strengthen their ability and training.

To address the lack of transparency in traditional manufacturing supply chain management, the vulnerability to data tampering, and the insufficient traceability capabilities, which result in a lack of trust between supply chain organizations and increased opportunity costs, this paper designed the TMSCT framework by using blockchain technology. Firstly, it designed a master-slave chain collaboration mechanism to enable trustworthy collaboration while protecting privacy. Secondly, it implemented a hybrid on-chain and off-chain storage mode to alleviate storage pressure on distributed nodes. Finally, it constructed a B-Merkle tree based on Bloom filter and Merkle tree to quickly determine if the current block contained the target data. Experimental results demonstrate that the B-Merkle tree effectively reduces the average processing latency of query requests. The proposed framework outperforms existing solutions in terms of data existence verification, privacy protection, flexibility, and alleviating storage pressure on nodes. [ABSTRACT FROM AUTHOR]

To mitigate the potential for control command mishaps during aircraft fly-arounds, a comprehensive risk assessment model was established in this study, employing a blend of fault tree analysis (FTA) and analytic hierarchy process (AHP). This model aids in the development of risk control strategies for controllers in the event of command accidents during fly-around control, and also validates the efficacy of the proposed measures. Risk factors were meticulously examined at each level to discern their interconnections, thereby facilitating the construction of a fault tree model for fly-around control command accidents. Subsequently, the Analytic Hierarchy Process was integrated to ascertain the weightage of each risk indicator tier. Concurrently, based on the cumulative weightage ranking of each index, fly-around control command accident control measures were suggested. The proposed plan was ultimately validated using Changsha Area Controlled Airspace as an example. The findings reveal that while factors such as thunderstorms, wind shear, convoluted coordination procedures, and aircraft deviation from planned routes continue to play a significant role in fly-around command incidents, their importance has diminished by 6. 2 percent. Moreover, issues such as a lack of experienced controllers, high sector traffic, and frequent scheme alterations have been effectively addressed. The results underscore that the proposed scheme can significantly reduce the prominence of basic events occurring in fly-around control command accidents. It also minimizes safety risks associated with extreme weather conditions and excessive workload, thereby enhancing the stability and reliability of the control system. [ABSTRACT FROM AUTHOR]

The citation analysis based on the citation frequency ignores the difference in the utility of citations to the cited documents, and it is inevitable that the resource evaluation and academic influence judgment based on this will be interfered by "invalid" citations. To eliminate "invalid" citations and improve the quality of measurement and evaluation data, the article selects typical features such as citation attributes. functions, objects, and emotions from the perspective of citation utility, and establishes a citation annotation framework, in order to test the effectiveness of logistic regression and support vector machine methods on automatic citation classification in annotated datasets, and to construct a "core citation recognition model from the perspective of utility". Specifically, in the data annotation stage, in addition to manual indexing, a large-scale pre trained language model dialogue system ChatGPT is also used for automatic classification and modeling performance testing, in order to provide new ideas for automatic citation classification methods and application practices.
