BACKGROUND: Acromion morphology is the most important external factor of degenerative rotator cuff tear, and studies on acromion morphology and acromion coverage have been continuing. OBJECTIVE: To investigate the coverage of acromion on rotator cuff tissue in three-dimensional space, measure coronal and sagittal parameters, and explore the relationship of acromial overhang, acromioglenoid angle and acromial coverage angle with degenerative full-thickness rotator cuff tears. METHODS: A total of 56 patients diagnosed with full-thickness rotator cuff tears by shoulder arthroscopic surgery or MRI in the Affiliated Hospital of Xuzhou Medical University from January 2022 to June 2023 were retrospectively collected as the tear group, while 48 patients with non-rotator cuff tear were included as the control group. Clinical data and chest CT data of the patients of the two groups were collected, and the shoulder blades of the patients were reconstructed using Mimics software. Acromial overhang, acromioglenoid angle and acromial coverage angle were measured in 3-matic software. The differences between the measurement parameters were compared between the two groups. Binary Logistic regression analysis and receiver operating characteristic curve analysis were performed to evaluate the ability of the measurement parameters to predict rotator cuff tear. It is generally believed that the parameter had good diagnostic value when the area under the receiver operating characteristic curve was greater than 0.8. RESULTS AND CONCLUSION: (1) The mean acromial overhang in patients with rotator cuff tears was greater than that in controls (P < 0.001). The mean acromial coverage angle was also greater in patients with rotator cuff tears than in controls (P < 0.001). There was no significant difference in the acromioglenoid angle between the two groups (P > 0.05). (2) Binary Logistic regression analysis showed that acromial overhang and acromial coverage angle were both risk factors for rotator cuff tear (P < 0.05). (3) Receiver operating characteristic curve analysis indicated that the areas under the curve of acromial overhang and acromial coverage angle were 0.725 and 0.865, respectively, and the optimal cutoff values were 36.15 mm and 60.65°. (4) The results showed that the acromial overhang and acromial coverage angle were greater in patients with rotator cuff tears than in patients without rotator cuff tears. Both were associated with degenerative full-thickness rotator cuff tears, and they could be used to predict rotator cuff tears, and the acromial coverage angle was more effective in predicting rotator cuff tears.

A strain YJ4 with antibacterial activity was isolated and screened from the intestine of crucian carp, its fermentation broth has strong bacteriostatic effect on Aeromonas hydrophila, Vibrio harveii, Vibrio alginolyticus, Vibrio parahaemolyticus and Aeromonas verge. Morphological characteristics, physiological and biochemical characteristics, 16S rDNA sequence and phylogeny and phylogenetic evolution were analyzed. The results showed that strain YJ4 had 99% homology with Bacillus subtilis, which was identified as Bacillus subtilis. The property study found that Bacillus subtilis YJ4 bacteria liquid was resistant to acid, salt and high temperature, had no toxic effect on fish. The experiment indicates that Bacillus subtilis YJ4 isolated has inhibitory effect on common aquatic pathogens, which has strong tolerance. It is suitable for adding to aquatic feed to prepare pellets and can be used as aquatic microecological preparations. [ABSTRACT FROM AUTHOR]

According to the heat transfer and flow resistance characteristics of the tube belt radiator, the three-dimensional flow and heat transfer model of shutter fin in belt-type radiator was established, and the effects of steering area number and length of the louver fin on the flow and heat transfer performance of radiator were investigated. The results show that when the head wind speed is constant, the heat transfer factor and friction factor of radiator under the arrangement of single-row pipe and three-row pipes are decreased with the increasing of the product of steering area length and number. When the products of steering area length and number are equal, the heat transfer factor and friction factor are increased with the increasing of steering area number. With the single-row pipe layout arranged, the comprehensive performance of radiator is the best when the steering area length and number are respective 1. 5 mm and 3. With three-row of pipes arranged, the comprehensive performance of radiator is the best when the steering area length and number are respective 3. 0 mm and 3. The optimal matching of steering area length and number can effectively improve the comprehensive performance of multi-row pipe layout and narrow the gap with that of single-row pipe layout.

Currently, most harmless disposal refrigerated vehicles use the global positioning system (GPS) to determine the position of disinfection stations and the transport routes of pigs died of diseases. However, the single navigation and positioning information might be unstable when the vehicle was running in remote mountainous area, the information transfer was not continuous, incomplete and untrue. In order to solve this issue, a monitoring system was designed based on radio frequency identification technology (RFID), Beidou navigation satellite system (BDS) and global positioning system (GPS). This paper makes full use of the BDS/GPS dual-mode receiver, which supports positioning and two-way communication functions. On the one hand, it can solve the problem of positioning information instability that occurs when using a single positioning. On the other hand, when the BDS navigation positioning system data appeared to show a deviation, The GPS positioning data from the WGS-84 coordinate system was converted to the CGCS2000 coordinate system of the BDS positioning system, to achieve the purpose of improving the acquisition accuracy of the transport vehicles location information. GAMIT software was used to calculate the 3D coordinates of the observation point, and it was analyzed for the positioning accuracy of combined navigation and single navigation. Floyd algorithm was combined to optimize transportation routes to search for the shortest transportation distance. The harmless transportation vehicles walking map could be drawn from the positioning information of the BDS/GPS dual-mode receiver. The message communication function of BDS satellite was used instead of GSM short message service to realize remote transmission between harmless transportation vehicles and control center. When pigs died of diseases are transported to fixed-point disinfection station, RFID reader will read the vehicle-mounted RFID active electronic tags to recognize the transport vehicles and the GPRS network will transmit the fixed-point disinfection monitoring data to the monitoring center. Monitoring center uses the ArcGIS map display to carry out the real-time monitoring of vehicle transport routes, and uses text to speech to realize the intelligent deployment and management of transport vehicles. Meanwhile, monitoring center obtains the transport routes of pigs died of diseases and the fixed-point disinfection monitoring information by analyzing the received data. After field test, the positioning accuracy of BDS/GPS dual mode receiver was 55.13% higher than that of BDS satellite positioning, and 52.71% higher than that of GPS satellite positioning. The networks packet losses value of vehicle terminal acquisition system was 0.26%, and the error rate of vehicle identification of the disinfection point was 0.97%. The results showed that the monitoring system met the requirements of the monitoring and management system in mountainous areas, and it ran reliable and stable. The study provides an effective method for a transport vehicle for the harmless treatment of dead pigs, accomplishes the comprehensive supervision and management of transport vehicles for the harmless treatment of dead pigs. This system can also be adopted as a reference to harmless disposal systems for other pigs that die of diseases, it has practical value. [ABSTRACT FROM AUTHOR]
