With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

OBJECTIVE To explore the research status, research hotspot and development trend of brucine by carried out the bibliometric analysis of the domestic and foreign literatures related to brucine. METHODS Literature related to brucine in CNKI and Web of Science database was systematically searched, and literature metrology method was applied based on CiteSpace 5.8.R3 software for visual analysis of publication year, core authors, countries, keywords, etc. RESULTS A total of 439 Chinese and 602 English literatures were included in this study. In the past 40 years, the number of publications related to brucine had shown a steady growth trend. The domestic high-yield authors were mainly members of Cai Baochang's research team. The research content of this team involved the content determination, anti-tumor effect, pharmacokinetics, processing and transformation, and development of new dosage forms of main alkaloids and corresponding nitrogen oxides components in Strychni Semen, etc. Based on country-by-country analysis, China had the highest number of publications, and further research cooperation with other countries was to be developed. Keyword analysis showed that the common research hotspots at home and abroad were mainly in two aspects:anti-tumor pharmacological activity and mechanism research, research on new drug delivery system of brucine. The research on brucine was still in the development stage, and the Chinese literatures had changed from quality control to pharmacological activity and new dosage forms; English literatures mostly focus on the fields of pharmacological activity, new dosage forms and asymmetric synthesis. CONCLUSION The research of brucine is still in the development stage, and the cooperation and communication between research teams need to be strengthened. Toxic reduction and efficiency enhancement will remain the focus and trend of future research.

Quantity is the key factor to ensure the safety and effectiveness of medicines. It is very important to study and determine the traditional measuring units and their quantity values of Tibetan medicine. Based on the literature records of Tibetan medicine and combined with modern experimental verification and investigation research, this study determined the reference, name, and conversion rate of traditional measuring units of Tibetan medicine. Meanwhile, through large sample sampling and repeated quantification of refe-rence of basic units, its weight and volume were clarified. The modern SI volume and weight unit values corresponding to the traditional volume and weight units of Tibetan medicine were deduced, and the correctness, reliability, and practicability of these determination results were demonstrated. This study also put forward some specific suggestions and reference values for formulating the standards of measuring units of weight and volume of Tibetan medicine. It is of great significance in guiding the processing, production, and clinical treatment of Tibetan medicine, and promoting the standardization and standardized development of Tibetan medicine.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.

BACKGROUND: Children and adolescents are in the growth and development stage, so the use of the same reconstruction methods as adults is easy to induce complications including limb length differences, high graft failure rate and re-surgical intervention. Simultaneously, the occurrence of osteoarthritis will also be advanced. OBJECTIVE: To explore the anatomical characteristics of the anterior cruciate ligament between children, adolescents and adults on MRI, and to provide an anatomical basis for the reconstruction of the anterior cruciate ligament in children and adolescents. METHODS: A retrospective analysis of patients undergoing knee MRI examination in Qingdao Municipal Hospital from October 2016 to October 2018 was conducted. These patients were divided into child and adolescent group and adult group (n=48 per group). The angle between the anterior cruciate ligament and the tibia and femur on the sagittal plane and the position of the anterior cruciate ligament tibial insertion, the angle between the anterior cruciate ligament and the tibia on the coronal plane, the tibial insertion of the anterior cruciate ligament and femur, and the position of the femur stop point on the axial position were measured in both groups. The data obtained from the measurement of the anterior cruciate ligament of children and adolescents were processed. The growth curves of the shape and position of the anterior cruciate ligament of children and adolescents were drawn, and the law of its growth changes was analyzed. RESULTS AND CONCLUSION: (1) The angle between the sagittal plane of the anterior cruciate ligament and the femur (t=﹣2.906, P<0.05), the angle between the sagittal plane of the anterior cruciate ligament and the tibia (t=﹣10.280, P < 0.05), the anterior cruciate ligament angle between the coronal plane and the tibia (t=﹣5.714, P<0.05) were smaller in the child and adolescent group than those of the adult group, and the difference was significant. (2) The ratio of the tibia coronal plane of the anterior cruciate ligament (t=﹣7.263, P < 0.05) and the ratio of the anterior cruciate ligament and femur axial plane (t=﹣7.378, P < 0.05) were lower in the child and adolescent group than those of the adult group, and the difference was significant. (3) There was no significant difference in the anterior cruciate ligament and tibia sagittal plane ratio (t=﹣1.588, P>0.05) and anterior cruciate ligament and femoral coronal surface ratio (t=﹣1.647, P>0.05) between the child and adolescent group and the adult group. (4) The growth curve results showed that during the growth and development, the angle between the anterior cruciate ligament and the femur and tibia on the sagittal plane and the angle with the tibia on the coronal plane changed from small to large (P<0.05). The relative position of the tibial insertion in the coronal position changed from small to large, which indicates that during the growth and development, the tibial insertion moved from inside to outside relative to the inside of the tibial plateau on the coronal plane (P < 0.05). (5) The relative position of femoral insertion in the axial position changed from small to large, suggesting that during the growth and development, the femoral insertion moved from the outside to the inside relative to the lateral femoral condyle (P<0.05). (6) There was no significant difference in the tibial insertion and the femoral insertion between the child and adolescent group and adult group (P>0.05).

Objective To compare the effects of general anesthesia and spinal anesthesia on prognosis of cesarean section in parturients with medium and severe pulmonary arterial hypertension (PAH).Methods Parturients with medium and severe PAH,at ≥ 24 weeks of gestation,aged 20-45 yr,undergoing elective cesarean section under general or epidural anesthesia from November 1,2011 to December 31,2017 in our hospital,were divided into general anesthesia group and epidural anesthesia group according to the anesthetic method.General anesthesia was combined intravenous-inhalational anesthesia.The highest temperature within 5 days after surgery,the lowest SpO2 (inhaling oxygen 2-4 L/min via a nasal tube) within 3 days after surgery,duration of intensive care unit stay,time of postoperative use of antibiotics,requirement for targeted drugs for pulmonary hypertension,results of laboratory tests (blood biochemistry,coagulation function),postoperative mechanical ventilation,length of hospital stay,and hospitalization costs were recorded.The Apgar score and weight of the newborn,postoperative complications and death of the newborn and parturients in hospital were recorded.Cox regression analysis was used to identify the risk factors after cesarean section in parturients with medium and severe PAH.Results Fifty-seven parturients were enrolled in this study,with 21 cases in general anesthesia group and 36 cases in epidural anesthesia group.Compared with general anesthesia group,the rate of postoperative mechanical ventilation was significantly decreased,the incidence of adverse events of parturients in hospital and mortality rate were decreased,the postoperative level of albumin was increased,activated partial thromboplastin time was shortened (P＜0.05),and no significant change was found in the other parameters in epidural anesthesia group (P＞ 0.05).The results of Cox regression analysis showed that anesthetic method and preoperative SpO2difference were independent risk factors for cesarean section-related adverse events and death of parturients with medium and severe PAH.The risk of adverse events and death of parturients was significantly higher in general anesthesia group than in epidural anesthesia group (P＜0.05).Conclusion Epidural anesthesia produces better prognosis than general anesthesia when used for cesarean section in parturients with moderate and severe PAH.
