BACKGROUND: Studies have shown that the T-shaped plate can be pre-bent to a suitable angle and shape to block the fracture fragments in the quadrilateral region of the acetabulum, especially the fracture line extending to the greater sciatic notch. OBJECTIVE: To investigate the effect of T-shaped plate in the operation of acetabular quadrilateral fracture. METHODS: Totally 31 patients who underwent acetabular fracture surgery in Second Affiliated Hospital of Inner Mongolia Medical University from January 2018 to April 2020 were selected as the research object, of which 18 patients were combined with reconstruction plate and T-shaped plate. During the operation, the reconstruction plate and pre-bending of T-shaped plate were carried out according to the fracture situation, and the transverse plate on the head side of T-shaped plate was bent to the tail end, making the whole plate close to a right angle to match the fracture and fix the fracture block at the top of the square area. The 13 patients were not applied with T-shaped plate as the control group. Other operations were the same as in the experimental group. After treatment, the operation time, intraoperative blood loss, incision length and fracture healing were observed; the X-ray score and the function of the affected hip were evaluated after fracture reduction. RESULTS AND CONCLUSION: (1) The patients were followed up regularly for 24-40 weeks. After good intraoperative reduction of quadrilateral fractures, prebent reconstruction plate and T-shaped plate were placed, and the plate was in good contact with the bone surface. (2) The operation time of the trial group was longer than that of the control group (P < 0.05), and the intraoperative blood loss was less than that of the control group (P < 0.05). (3) Fracture reduction was evaluated according to Matta standard. The excellent and good rate of the trial group was 89% (16/18), and the excellent and good rate of the control group was 85% (11/13). The complete weight-bearing time of the trial group [(7.9±1.6) weeks] was better than that of the control group [(9.5±2.1) weeks] (P < 0.05). (4) It is concluded that T-shaped plate combined with reconstruction plate involving fractures in the quadrilateral region of the acetabulum has a good reduction effect, simple operation, less intraoperative blood loss, and short complete weight-bearing time.

BACKGROUND: 3D bioprinting has become a crucial research field of tissue engineering with the unceasing development of science and technology. Nevertheless, some limitations cannot be resolved. 4D bioprinting is the most emerging technology, and has become the major solution for the next generation of tissue engineering. OBJECTIVE: To introduce the materials and methods of 4D bioprinting in accordance with various shape transformation principles, and to explore the application of 4D bioprinting to tissue engineering and the current challenges. METHODS: “4D bioprinting, 4D biofabriation, printing, smart materials, smart scaffold, shape memory polymers, tissue engineering” in Chinese and English were utilized as search terms. A total of 127 related articles published from January 1, 2016 to January 1, 2021 were retrieved from CNKI, PubMed, and SCIE databases. After screening out by the first author and adding high-quality references, 106 articles were included for review. RESULTS AND CONCLUSION: (1) 4D bioprinting, the latest emerging technology, combines the concept of time with 3D bioprinting as the fourth dimension. 4D bioprinting can create complex and functional structures. (2) 4D bioprinting can make dynamic 3D biological structures by using smart materials. These structures can alter shape under various stimuli. (3) The functional transformation and maturation of printed cell structures are also considered a form of 4D bioprinting. (4) This technology provides an unprecedented potential for tissue engineering. In the field of biomedicine, although this technology has attracted great attention, more research and development are needed to realize clinical application, because it is still in the emerging stage.

Retrieving surface Soil Moisture (SM) from CYGNSS has attracted great attention in recent years, yet its accuracy and efficiency should be further improved. Here, a pre-classification strategy combined with Artificial Intelligence (AI) algorithm is proposed to predict SM from CYGNSS data. This strategy can improve the accuracy of SM estimation due to the use of Al algorithm and is versatile and easy to use. The field SM data of China in 2018 are used as real ground truth values for modeling and prediction. The results show that the predicted SM is in good agreement with the referenced SM. The correlation coefficient (R) between SM retrieved from CYGNSS and ground truth data is as high as 0. 8, and the mean values of Root Mean Square Error (RMSE) and unbiased root mean square error (ubRMSE) are 0. 059 cm³/cm³ and 0. 050 cm³/cm³, respectively. Meanwhile, the results show that the Al-based pre-classification strategy not only significantly improves the accuracy of SM estimation from CYGNSS, but is applicable to other regression and prediction fields for its good generalization and expansibility.

Wireless body sensor network( WBSN) has attracted wide attention in the field of telemedicine monitoring the special population and so on. The energy consumption problem has become a major challenge for the development of the WBSN, and the transmission power control algorithm can save energy consumption effectively. In order to save energy consumption,this paper designed an algorithm based on SPIDNN, which could be used to improve the energy efficiency of WBSN. It adjusted the size of the transmission power dynamically by using the PID control algorithm with self-learning. This paper compared the proposed algorithm with the multiplicative increase additive decrease ( MIAD) algorithm and the algorithm based on the derivative of proportion .integral,derivative(PID). The experimental results show that the proposed algorithm not only improves the packet rate,but also guarantees the quality of the link. In the same experimental environment, the total energy consumption of sending 2 000 packets is reduced by 20% and 16.6% respectively.is superior to MIAD and PID control algorithm, which provides a better solution for the control of energy saving for sensor in wireless domain network.
