Objective:To investigate the relationship between the location of anterior cruciate ligament rupture (ACL) and the areas of bone bruises in patients with an acute ACL injury.Methods:A retrospective study was conducted on MRI of patients with ACL injuries from January to June 2019. According to the location of the ACL rupture on the distal to proximal length, the patients were divided into 5 groups, namely Type I, >90%; Type II, 75%-90%; Type III, 25%-75%; Type IV, 10%-25%, Type V, <10%. Gender, weight, body mass index, depth of lateral femoral condyle notch, and medial meniscus injury were compared among the five groups. The sagittal plane images of ePDWSPIRCLEAR sequence were selected to define the layer with the largest contusion areas of femur and tibia respectively. The maximum bone contusion areas of these two layers was measured using Image J 1.52t software.Results:Among the 63 cases of acute ACL injury, three cases (4.8%) were with type I tear, 14 cases (22.2%) with type II tear, 40 cases (63.5%) with type III tear, 2 cases (3.2%) with type IV tear, and 4 cases (6.3%) with Type V tear. There was no contusion of lateral femoral condyle or lateral tibial plateau bone in type I and type IV. The lateral femoral condyle bone contusion areas was 0 (0, 64.12) mm 2 in type II, 182.34 (86.58, 334.38) mm 2 in Type III, 38.64(0, 193.36) mm 2 in Type V with statistically significant difference ( H=21.665, P=0.000). The largest areas of bone contusion in the lateral tibial plateau was 76.78(28.25, 205.57) mm 2 in type II, 120.93(51.78, 239.37) mm 2 in Type III, 190.51(80.86, 238.75) mm 2 in Type V with statistically significant difference ( H=11.939, P=0.018). The maximum bone contused areas of the lateral tibial plateau in the medial meniscus injury group was 48.0(0, 105.97) mm 2, which was smaller than that in the non-injury group 185.67(54.36, 257.41) mm 2 ( H=8.848, P=0.003). The maximum bone contusion areas of the lateral femoral condyle in the injured group was 162.19(63.03, 301.33) mm 2, which was greater than 0(0, 103.37) mm 2 in the uninjured group ( H=11.554, P=0.001). Conclusion:ACL rupture often occurs in the middle segment. The middle segment ACL fracture combined with lateral meniscus injury had with the highest probability and with the largest area of bone contusion of lateral femoral condyle. The fracture of the ACL at the farthest terminal has the largest bone contusion areas of the lateral tibial plateau and with the lowest probability of combined injury of the medial meniscus.

Team training significantly affects the performance of clinicians in neonatal resuscitation, which plays an important role in improving outcomes of asphyxiated newborns. Since 2016, team training was formally described in the Textbook of Neonatal Resuscitation, including 10 key points, which were summarized into three core elements in this review: teamwork, communication, and leadership. We review the application of these three elements in current team training and the main training approaches, aiming to offer a framework for standardized team training and to improve the success rate of neonatal resuscitation.

Objective:To observe the clinical effect of Shutiao Decoction on patients with coronary heart disease and anxiety and depression. Methods:Sixty patients with stable coronary artery disease and anxiety and depression from January 2019 to December 2019 in Kunming Municipal Hospital of Traditional Chinese Medicine were selected. They were divided into a treatment group of 30 cases and a control group of 30 cases according to random number table method. The control group recieved Western medicine routine treatment combined with psychological intervention, the treatment group was treated with Shutiao Decoction on the basis of the control group, and the treatment course of both groups was 4 weeks. Before and after treatment, TCM syndrome score, Seattle Angina Scale (SAQ), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were evaluated. The adverse events were recorded during treatment and clinical efficacy was evaluated. Results:After treatment, the total effective rate in the treatment group was 90.0% (27/30), the control group was 73.3% (22/30), where the difference between the two groups was statistically significant ( Z=-2.515, P=0.012). After treatment, the TCM syndrome score (9.37 ± 6.47 vs. 18.37 ± 6.58; t=-5.341, P<0.01) of the treatment group was significantly lower than that of the control group. Among SAQ domains’ scores, the physical activity limitation, and the stable state of angina pectoris, angina attack in the treatment group were significantly higher than those of the control group ( t values were 2.294, 7.698, 4.677, 3.215, respectively, P<0.05 or P<0.01). The HAMA score of the treatment group was significantly lower than that of the control group (9.20 ± 5.26 vs. 12.17 ± 4.88; t=-2.266, P=0.027). The HAMD score in the treatment group was significantly lower than that of the control group (11.27 ± 5.83 vs. 15.03 ± 6.16; t=-2.433, P=0.018). During the treatment period, the incidence of adverse reactions was 3.33% (1/30) in the treatment group and 6.67% (2/30) in the control group. There was no statistically significant difference between the two groups ( χ2=0.351, P=0.554). Conclusion:Shutiao Decoction combined with western medicine routine treatment can improve patients’ TCM syndromes, relief angina pectoris, anxiety and depression.

Exosome is a sort of vesicle structure attached to cell membrane and released by cells, which contains numerous bioactive molecules, such as proteins, lipids, mRNA, microRNA and DNA fragments. These bioactive molecules are involved in the regulation of many biological processes, not only the participation in the occurrence and development of diverse diseases, but also the close relationship with the invasion and metastasis of tumors. The recent study has indicated that lots of exosomes released from cancer cells participate in a variety of pathological processes as a messenger of cell functions. This article will elaborate the function and application of exosomes in some malignant cancers.

Medical students′ professional spirit cultivation is an important content as well as a basic require-ment of the Preeminent Doctor Education and Training Plan. Currently, there are several problems in medical tal-ents′professional spirit cultivation, such as the unstandardized curriculum, the lack of subjective experience, and the ignorance of the unity of education stages, student differences and coherence. This study intends to explore thedouble teacher method, in which both clinical teaching doctors and medical ethics teachers engage in the medi-cal students′professional spirit cultivation. Its purpose is to build a bridge between medical ethics education in uni-versities and the clinical practice, and further to integrate them through doctors′ and teachers′ joint participation, which will significantly enhance medical students′practice ability of medical moral.
