The bone immune microenvironment is closely related to the onset and progression of bone destruction in rheumatoid arthritis. The Chinese medicine diagnosis of rheumatoid arthritis bone destruction is mostly "deficiency of liver and kidney", "damp-heat paralysis and obstruction" and "phlegm stasis and obstruction of ligaments", thus we propose three main treatment principles, including tonifying the liver and kidney, clearing heat and dampness, activating blood and resolving phlegm. In this paper, we try to discuss the ideas and methods of using Chinese medicine to intervene in the bone immune microenvironment from the perspective of the Chinese medicine pathogenesis of rheumatoid arthritis bone destruction.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

OBJECTIVE: To investigate the safety and efficacy of reinforced radiculoplasty in the treatment of symptomatic sacral Tarlov cysts (TCs). METHODS: A retrospective analysis was performed on the clinical data and follow-up data of 71 patients with symptomatic sacral TCs who underwent reinforced radiculoplasty in the Neurosurgery Department of Peking University Third Hospital from June 2018 to March 2021. All the operations were performed under neuroelectrophysiological monitoring. Intraoperative cyst exploration, partial resection of the cyst wall, narrowing of the leak, nerve root sleeve radiculoplasty and artificial dural reinforcement were performed. The incidence of postoperative complications and new neurological dysfunction was analyzed. Visual analogue scale (VAS) was used to assess the changes of pain before and after surgery. The Japanese Orthopedics Association (JOA) low back pain score was used to evaluate the changes in nerve function before and after surgery. RESULTS: In the study, 71 patients had 101 TCs, 19 (18.8%) TCs originated from the left S1 nerve, 26 (25.7%) originated from the left S2 nerve, 3 (3.0%) originated from the left S3 nerve, 14 (13.9%) originated from the right S1 nerve, 33 (32.7%) originated from the right S2 nerve, 6 (5.9%) originated from the right S3 nerve, all the TCs underwent reinforced radiculoplasty. Deep infection (1 case), subcutaneous effusion (1 case), fat li-quefaction (1 case) and urinary tract infection (4 cases) were recorded postoperatively. The patients were followed up for 12-43 months (median, 26 months). Two cases had new urinary retention after operation, and the catheter was removed at the end of the first and second months respectively. One case had new fecal weakness, which improved after 3 months. Compared with preoperation, VAS decreased significantly at the last follow-up [median, 6 (4-9) vs. 1 (0-5), Z=-7.272, P < 0.001], JOA score increased significantly [median, 20 (16-25) vs. 27 (18-29), Z=-7.265, P < 0.001]. There were 18 cured cases (25.4%), 41 excellent cases (57.7%), 8 effective cases (11.3%), and 4 invalid cases (5.6%). The total efficiency was 94.4% (67/71). Two (1.98%) cysts recurred. CONCLUSION For patients with symptomatic sacral TCs, reinforced radiculoplasty can significantly improve the pain and nerve function, which is safe and reliable.

Intertrochanteric fractures have become a severe public health problem in elderly patients. Proximal femoral nail anti-rotation (PFNA) is a commonly used intramedullary fixation device for unstable intertrochanteric fractures. Pelvic perforation by cephalic screw is a rare complication. We reported an 84-year-old female who fell at home and sustained an intertrochanteric fracture. The patient underwent surgery with PFNA as the intramedullary fixation device. Routine postoperative examination revealed medial migration of the helical blade that eventually caused pelvic perforation. We performed a cemented total hip arthroplasty as the savage procedure. At the latest follow-up of 12 months after total hip arthroplasty, the patient had no pain or loosening of the prosthesis in the left hip. Pelvic perforation should be considered when choosing PFNA as the intramedullary fixation device, especially in patients with severe osteoporosis wherein the helical blade can be easily inserted during the operation. The lack of devices to avoid oversliding of the helical blade in PFNA is an unreported cause of this complication and should be considered in such cases.

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.

PURPOSETo observe the therapeutic effect of interventional embolization and haemorrhage control in multiple trauma patients with a major abdominal or pelvic injury.

METHODSData of 160 multiple trauma patients with a major abdominal or pelvic injury were retrospectively analyzed. They were admitted into the Department of Emergency of the First Affiliated Hospital of Zunyi Medical College from October 2013 to April 2016. Eighty-seven patients who received emergent intervention for embolization and haemorrhage control were set as group A, including 72 males and 15 females, with an average age of (39.32 ± 14.0) years. Patients underwent emergent intervention for embolization and hemostasis. The other 73 patients who received traditional surgeries were set as group B, including 62 males and 11 females, with an average age of (38.48 ± 13.12) years. The time from admission to emergency intervention, the time of interventional embolization, transfusion during hospitalization, length of stay and prognosis were observed. The whole treatment and prognosis were compared between group A and group B.

RESULTSIn group A, the average time from admission to intervention exploration was (132.05 ± 86.80) min, the average operation time was (149 ± 49.69) min, the average hospitalization time was (18.37 ± 4.71) days, the average amount of RBC transfusion during hospitalization was (7.2 ± 4.33) units, and the mortality was 4.60% (4 patients died). The corresponding data in group B were respectively (138.95 ± 82.49) min, (183 ± 52.39) min, (22.72 ± 6.63) days, (12.23 ± 5.43) units, and 9.59% (7 cases died). There was no statistical difference in the time from admission to operation between the two groups (p > 0.05), but there was statistical difference in operation time, RBC transfusion, hospitalization time, prognosis, and mortality between the two groups (all p < 0.05).

CONCLUSIONThe emergent intervention for embolization and haemorrhage control of multiple trauma patients with a major abdominal or pelvic injury and visceral organ haemorrhage has the advantages of less trauma, shorter operation time, shorter hospital stay, less blood transfusion in comparison to the traditional emergency surgeries.

OBJECTIVETo observe the effect of different manipulative reduction for children's distal radioulnar fracture and dorsal dislocation.

METHODSFrom June 2013 to June 2014, 80 children with distal radioulnar fracture and dorsal dislocation were treated by bone setting manipulative reduction including 51 males and 29 females with an average age of 6.5 years old ranging from 3 to 14 years old. Time from injury to treatment was 1 h to 6 d, 31 cases were on the right, 49 cases were on the left. Among them, 45 cases were type I of overlapping displacement, 35 cases were type II. The displacement of the fracture was observed by clinical manifestations and X-ray examination. Under fluoroscopy, different techniques were used for reduction and fixation. After 3 weeks of over wrist fixation, the splints were overturned and fixed again for 1 to 2 weeks, then were removed. The wrist joint function was evaluated based on Dienst criteria.

RESULTSEighty cases of fracture were successfully operated one time, all reached anatomic reduction or near anatomic reduction. Eighty children were followed up for 3 months to 1 year. All the fractures healed, and the healing time was 4 to 5 weeks with an average of 4.6 weeks. All patients removed the splint 3 months later, the results were excellent in 72 cases, good in 7 cases and fair in 1 case, the excellent and good rate was 98.75%.

CONCLUSIONSBone setting manipulation for children's distal radioulnar fracture and dorsal dislocation can get good reduction. At 1 month after the removal of the splint, wrist function and finger strength gradually recovered and returned to normal after 3 months.

OBJECTIVETo explore the clinical effect of closed reduction and minimally invasive treatment of humeral shaft fractures in children.

METHODSFrom July 2011 to April 2015, 39 cases of pediatric humeral shaft fractures were treated by closed reduction and external fixation, including 27 males and 12 females with a mean age of 8.6 years old ranging from 3 to 14 years old. Time from injury to the treatment was 2 h to 7 days with an average of 2.7 days. There were 6 cases of upper fracture, 21 cases of middle fracture and 12 cases of lower fracture. All children were closed injury, appeared pain, swelling, local deformity and limited mobility and other symptoms after injury. X-ray examination showed humeral shaft fracture. Neer score of shoulder joint function and HSS score of elbow joint function were used to record and analyze the pain, function and activity of shoulder and elbow joint before and after treatment.

RESULTSAll the 39 cases were followed up for 6 to 12 months with a mean of 8.6 months. Two cases appeared postoperative superficial infection of the needle, and healed after dress; other cases gained good pinhole healing. There were significant differences in the pain, function and activity of the shoulder of Neer score before and after the treatment (<0.05). There were significant differences in the pain and function of the elbow of HSS before and after treatment (<0.05). According to the evaluation of Neer score of shoulder function, the total score was 88.82±2.50, 29 cases were excellent, 9 cases were good, and 1 case was fair. According to the evaluation of HSS score of elbow joint function evaluation, the total score was 91.51±5.09, 30 cases were excellent, 7 cases were good, 2 cases were general.

CONCLUSIONSManual closed reduction combined with external fixation for the treatment of humeral shaft fractures in children has advantages of less trauma, definite reduction effect, reliable fixation and benefit for early functional exercise of the shoulder and elbow joint. This therapy can be used as one of clinical methods for the treatment of humeral shaft fractures in children.

Objective To compare the outcomes of percutaneous pedicle instrumentation combined with vertebral augmentation or vertebra pedicle instrumentation for treatment of osteoporotic thoracolumbar fractures (OVCF) in elderly patients.Methods A retrospective case cohort study was conducted on 62 patients with OVCF manifesting non-neurological symptoms treated from January 2009 to January 2012.There were 22 males and 30 females,with a mean age of 61.3 years (range,55 to 70 years).Fracture level was T11 in 8 patients,T12in 20,L1 in 22 and L2 in 12.Treatments included percutaneous pedicle instrumentation combined with vertebral fracture fixation in 36 patients (Group A) and percutaneous pedicle instrumentation combined with vertebral augmentation in 26 patients (Group B).Operation time,intraoperative blood loss,anterior vertebral body height,sagittal Cobb angle and visual analogue score (VAS) were compared between the two groups.Results All patients were followed up for average 46.5 months (range,36 to 58 months).Operation time in Group A [(82.6 ±16.2) min] was shorter than that in Group B [(96.8 ± 20.6) min] (P ＜ 0.05).Blood loss in Group B [(40.5 ± 10.2) ml] was less than that in Group A [(52.2 ± 15.5) ml] (P ＜ 0.05).Before operation and 3 days and 1 year after operation,the anterior vertebral body height and sagittal Cobb angle in Group A showed no significant differences compared to Group B (all P ＞ 0.05).At the final follow-up,the ratio of anterior vertebral height and Cobb angle in Group B [(87.8 ± 2.5) ％,(7.8 ± 3.5) °] were better than these in Group A [(82.6 ±3.2)％,(9.1 ± 1.8)°] (P＜0.05).VAS showed no statistical significance between the two groups before and after operation (P ＞ 0.05).Bone cement leakage was seen in four patients in Group B.During the perioperative period,there were 3 patients with lung infection in Group A and 1 patient with lower limb deep vein thrombosis in Group B.No implant failure occurred in both groups.Conclusion Both procedures are effective in treating elderly patients with OVCF,but percutaneous pedicle instrumentation combined with vertebral augmentation is associated with better results in maintaining vertebral height and preventing kyphosis.
