OBJECTIVE: This study aimed to explore the interplay between the life-course body mass index (BMI) trajectories and insulin resistance (IR) on incident diabetes. METHODS: This longitudinal cohort included 2,336 participants who had BMI repeatedly measured 3-8 times between 1989 and 2009, as well as glucose and insulin measured in 2009. BMI trajectories were identified using a latent class growth mixed model. The interplay between BMI trajectories and IR on diabetes was explored using the four-way effect decomposition method. Logistic regression and mediation models were used to estimate the interaction and mediation effects, respectively. RESULTS: Three distinct BMI trajectory groups were identified: low-stable ( n = 1,625), medium-increasing ( n = 613), and high-increasing ( n = 98). Both interaction and mediation effects of BMI trajectories and IR on incident diabetes were significant ( P < 0.05). The proportion of incident diabetes was higher in the IR-obesity than in the insulin-sensitivity (IS) obesity group (18.9% vs. 5.8%, P < 0.001). After adjusting for covariates, the odds ratios (95% confidence intervals) of the IR, IS-obesity, and IR-obesity groups vs. the normal group were 3.22 (2.05, 5.16), 2.05 (1.00, 3.97), and 7.98 (5.19, 12.62), respectively. IR mediated 10.7% of the total effect of BMI trajectories on incident diabetes ( P < 0.001). CONCLUSION We found strong interactions and weak mediation effects of IR on the relationship between life-course BMI trajectories and incident diabetes. IS-obesity is associated with a lower risk of incident diabetes than IR-obesity.

Objective:To improve the understanding of pediatric acute promyelocytic leukemia with TTMV::RARA fusion gene positive caused by torque teno mini virus (TTMV).Methods:A retrospective analysis was conducted on the clinical data of a patient with relapsed TTMV::RARA fusion gene-positive acute promyelocytic leukemia who was admitted to Children's Hospital Affiliated to Zhengzhou University in July 2024, and literature review was conducted.Results:The patient was a girl with the age of 5 years and 7 months. She presented with joint pain and fever. Combined with bone marrow cell morphology and whole transcriptome sequencing, she was diagnosed with TTMV::RARA fusion gene-positive acute promyelocytic leukemia. After induction therapy with regimens such as retinoic acid +daunorubicin+cytarabine and retinoic acid+venetoclax+homoharringtonine, the joint pain was relieved, but the primary disease did not improve. Subsequently, there was no regular treatment. One year later, the disease recurred and was complicated with severe infection. Her condition improved following anti-infection and induction therapy.Conclusions:TTMV::RARA fusion gene-positive pediatric acute promyelocytic leukemia is a special type of acute promyelocytic leukemia caused by the insertion of viral sequences from TTMV infection. It is rare in clinical practice and difficult to treat, and the overall prognosis may be poor.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective:To compare the efficacy of robot-assisted percutaneous reduction and screw fixation versus open reduction and plate fixation via the sinus tarsi approach in the treatment of Sanders types II and III calcaneal fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 82 patients (90 feet) with calcaneal fractures admitted to the Department of Orthopedic Trauma, Beijing Jishuitan Hospital, Capital Medical University from January 2020 to April 2024, including 74 males and 8 females, aged 24-87 years [(46.4±12.1)years]. According to Essex-Lopresti classification, the fractures were classified as tongue-type in 43 patients and joint-collapse-type in 47. According to Sanders classification, 69 feet were classified as type II and 21 as type III. Forty-seven patients (52 feet) were treated with robot-assisted percutaneous reduction and screw fixation (screw fixation group) and 35 (38 feet) with open reduction and plate fixation via the sinus tarsi approach (plate fixation group). The two groups were compared in terms of the operation duration, intraoperative blood loss, length of hospital stay and time to weight-bearing. The width, height, length, B?hler angle and Gissane angle of the calcaneus before surgery and at 1 day after surgery were compared. The Maryland foot and ankle function score, American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot function score, and visual analogue scale (VAS) score at 1, 3 months postoperatively, and at the last follow-up were compared. The incidence of postoperative complications and removal rate of internal fixation were also detected in the two groups.Results:All the patients were followed up for 9-60 months [(30.0±14.5)months]. There was no significant difference in the operation duration between the two groups ( P>0.05). The intraoperative blood loss, length of hospital stay and time to weight-bearing in the screw fixation group were 10.0(10.0, 20.0)ml, 7.0(5.0, 8.0)days and (5.0±0.8)weeks, which were significantly less or shorter than 30.0(20.0, 50.0)ml, 8.0(6.0, 11.0)days and (6.9±0.7)weeks in the plate fixation group ( P<0.05). The width, height, length, B?hler angle and Gissane angle of the calcaneus at 1 day after surgery were (43.4±4.2)mm, (46.2±4.0)mm, (81.6±5.1)mm, 27.1(20.4, 30.4)° and (113.4±10.1)° in the screw fixation group, which were all improved compared with those before surgery [(47.8±4.6)mm, (39.3±4.8)mm, (79.2±5.9)mm, 9.5(0.0,16.5)° and (119.3±13.4)°] ( P<0.01). The width, height, length and B?hler angle of the calcaneus at 1 day after surgery were (41.6±5.7)mm, (48.4±4.8)mm, (83.1±5.7)mm and 27.3(21.3, 31.6)° in the plate fixation group, which were all improved compared with those before surgery [(47.8±5.0)mm, (41.7±5.1)mm, (80.1±5.9)mm and 12.9(7.2,19.8)°] ( P<0.01), with no significant difference in the Gissane angle ( P>0.05). Before surgery and at 1 day postoperatively, no significant differences were found in the width, length, B?hler angle or Gissane angle of the calcaneus between the two groups ( P>0.05), while the height of the calcaneus in the screw fixation group was lower than that in the plate fixation group ( P<0.05). At 1 month after surgery and at the last follow-up, there were no significant differences in the Maryland foot and ankle function score, AOFAS ankle and hindfoot function score, and VAS score between the two groups ( P>0.05). At 3 months after surgery in the screw fixation group, the Maryland foot and ankle function score was (79.7±3.8)points, significantly higher than (74.7±2.8)points in the plate fixation group ( P<0.01); the AOFAS ankle and hindfoot function score was (77.1±5.0)points, significantly higher than (70.1±3.6)points in the plate fixation group ( P<0.01); the VAS score was 1.0(1.0, 2.0)points, significantly lower than 2.5(2.0, 3.0)points in the plate fixation group ( P<0.01). No significant difference was detected in the incidence of postoperative complications between the two groups ( P>0.05). The removal rate of internal fixation was 10% (5/52) in the screw fixation group, significantly lower than 29% (11/38) in the plate fixation group ( P<0.05). Conclusion:Compared with open reduction and plate fixation via the sinus tarsi approach, robot-assisted percutaneous reduction and screw fixation has the advantages of less intraoperative blood loss, shorter hospital stay, earlier weight-bearing exercises, better early functional recovery and pain relief, and lower internal fixation removal rate in the treatment of Sanders types II and III calcaneal fractures.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.
