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.

Objective:To compare the diagnostic efficacy of 18F-fibroblast activation protein inhibitor (FAPI) PET/MR and contrast-enhanced CT in detecting metachronous ovarian metastasis after gastric signet-ring cell carcinoma (GSRCC) surgery, and to evaluate its impact on clinical decision-making. Methods:This study employed a diagnostic test design. A retrospective analysis was conducted on 26 female patients with suspected metachronous ovarian metastasis following GSRCC resection between January 2023 and June 2025 in Renji Hospital, Shanghai Jiao Tong University School of Medicine. All patients underwent both 18F-FAPI PET/MR and contrast-enhanced CT within 2 weeks. Using histopathology or clinical imaging follow-up (≥6 months) as the reference standard, the diagnostic performance of both modalities was compared (McNemar test, Fisher exact test and Delong test), and changes in clinical management were analyzed. Results:Metachronous ovarian metastasis was confirmed in 12 patients (22 lesions). 18F-FAPI PET/MR showed significantly higher sensitivity (90.9%(20/22) vs 72.7%(16/22); χ2=4.10, P=0.043), specificity (100%(30/30) vs 50.0%(15/30); χ2=13.01, P<0.001), and accuracy (96.2%(50/52) vs 59.6%(31/52); χ2=15.43, P<0.001), compared to contrast-enhanced CT, with a significantly higher AUC (0.964 vs 0.815; Z=2.85, P=0.015). It also demonstrated superior detection of extraovarian metastases, including anastomotic recurrence, peritoneal spread, and lymph node involvement ( P values: 0.004-0.031), and identified 5 additional rare-site metastases in 3 patients that were missed by contrast-enhanced CT. Based on 18F-FAPI PET/MR findings, clinical management was adjusted in 6 patients with metastasis. Conclusion:18F-FAPI PET/MR outperforms contrast-enhanced CT in diagnosing metachronous ovarian metastasis and performing whole-body restaging in post-surgical GSRCC patients, therapy provides critical evidence for informing decision-making.

Objective:To investigate the relationship between daily physical exercise and frailty state among elderly inpatients in internal medicine department.Methods:A cross-sectional study was conducted among eligible elderly patients who hospitalized at the internal medicine department of Beijing Hospital from September 2018 to March 2019.Frailty was screened using the FRAIL scale, and their pre-hospitalization daily physical exercise was assessed through a questionnaire upon admission.The statistical methods include correlation analysis and logistic regression univariate and multivariate analysis.Results:A total of 533 eligible elderly patients in internal medicine were included in the study, with 129(24.2%)frail, 296(55.5%)pre-frail, and 108(20.3%)non-frail patients.328 patients(61.5%)exercised more than 5 times a week, while 102 patients(19.1%)hardly exercised at all.Physical exercise frequency had negative correlation with the FRAIL frailty score( r=-0.576, P<0.001).Both univariate and multivariate logistic regression analysis shown daily physical exercise frequency was significantly associated with frailty( OR=0.56, 95% CI: 0.49-0.65, P<0.001)among elderly inpatients in internal medicine. Conclusions:For elderly inpatients in internal medicine department, daily physical exercise frequency is closely related to frailty status, serving as an independent factor in reducing the occurrence of frailty.Therefore, increasing the frequency of daily physical exercises is an effective measure to reduce the risk of frailty for this group of patients.

Objective:To investigate the analgesic effect of Opisthoplatia orientalis Burm. polypeptides (OOBP) on postherpetic neuralgia (PHN) induced by resiniferatoxin (RTX) in rat models, and its effect on the phosphatase and tensin homologue deleted on chromosome ten (PTEN) -induced kinase 1/Parkin (PINK1/Parkin) signaling pathway. Methods:Thirty-two special pathogen-free rats were randomly divided into 2 groups: a blank control group ( n = 8) receiving intraperitoneal injections of physiological saline (0.20 mg/kg) , and a model group ( n = 24) receiving intraperitoneal injections of RTX (0.20 mg/kg) to establish the PHN rat model. The rats' paw withdrawal mechanical threshold (PWMT) was measured on days 1, 4, 7, and 10 after RTX injections. After 10 days of RTX treatment, rat models were randomly assigned to 3 subgroups: PHN group, OOBP group, and gabapentin group, with 8 rats in each group. The OOBP group and gabapentin group were gavaged with OOBP (equivalent to 0.9 g raw drug per kg) and gabapentin (27 mg/kg) respectively, while the PHN group and control group were gavaged with physiological saline. All treatments lasted for 3 weeks, during which PWMT was continuously monitored. One hour after the final dose, rats were sacrificed, and spinal cord tissues and serum samples were collected. Hematoxylin-eosin (HE) staining was performed to observe spinal pathological changes, enzyme-linked immunosorbent assay (ELISA) to detect serum levels of interleukin-10 (IL-10) , tumor necrosis factor-α (TNF-α) , β-endorphin (β-EP) , and calcitonin gene-related peptide (CGRP) , and Western blot analysis to determine the expression of PINK1, Parkin, and ubiquitin-binding protein P62 in rat spinal cord tissues. The entropy weight method was applied to comprehensively evaluate the effect of OOBP on the above cytokines, proteins and other pharmacodynamic indicators in rat models of PHN. Results:From day 1 to day 10 after modeling, PWMT values in the model group were significantly lower than those in the blank control group (all P < 0.05) , and also significantly lower than baseline values prior to modeling (all P < 0.05) . Histopathological analysis of rat spinal cord tissues showed less pathological changes (such as Nissl body swelling and neuronal necrosis) but more normal Nissl bodies in both the gabapentin group and OOBP group compared with the PHN group. ELISA revealed significantly decreased serum levels of TNF-α and CGRP but significantly increased serum levels of β-EP and IL-10 in the OOBP group compared with the PHN group (all P < 0.05) . Western blot analysis showed that expression levels of PINK1 and Parkin were significantly lower in the gabapentin group (0.441 ± 0.061, 0.597 ± 0.180, respectively) and the OOBP group (0.666 ± 0.117, 0.481 ± 0.073, respectively) than in the PHN group (1.033 ± 0.085, 1.088 ± 0.040, respectively, all P < 0.05) ; in contrast, the P62 expression significantly increased in the gabapentin group (0.810 ± 0.086) and OOBP group (0.902 ± 0.153) compared with the PHN group (0.543 ± 0.082, both P < 0.05) . The entropy weight analysis showed that the comprehensive scores were 0.222 and 0.229 in the OOBP group and the gabapentin group respectively, suggesting a greater overall therapeutic effect of OOBP. Conclusion:OOBP may exert analgesic effects in rat models of PHN by downregulating the expression of inflammatory factors and pain-related factors and modulating the PINK1/Parkin signaling pathway, thereby inhibiting mitochondrial autophagy in spinal neurons and reducing inflammatory responses.

Objective:To analyze the efficacy of phantom-less quantitative computer tomography (PL-QCT) for the diagnosis of osteoporosis in patients with lumbar degenerative diseases.Methods:From October 2021 to October 2023, a total of 1 248 patients with lumbar degenerative disease who did not receive anti-osteoporosis treatment in the Department of Spine Surgery, Tianjin Hospital were retrospectively analyzed. There were 520 males and 728 females, aged 62.31±9.37 years (range, 40-87 years), height 1.66±0.08 m (range, 1.43-1.89 m), weight 69.04±8.27 kg (range, 49-93 kg). The mean body mass index was 26.11±3.67 kg/m 2 (range, 14.40-37.11 kg/m 2). Dual-energy X-ray absorptiometry (DXA) and PL-QCT were used to diagnose osteoporosis, and the detection rates of the two diagnostic methods were compared. The receiver operating characteristic (ROC) curve of PL-QCT for the diagnosis of osteoporosis was drawn, the area under the curve (AUC) and 95% confidence interval (CI), sensitivity and specificity were calculated. Results:Among 1 248 patients with lumbar degenerative diseases, 626 (50.2%) were diagnosed as osteoporosis by PL-QCT, 423(33.9%) were diagnosed by spine DXA, 488(39.1%) were diagnosed by hip DXA and 539 patients(43.2%) were diagnosed by dual-site DXA. The detection rate of osteoporosis of PL-QCT was higher than that of spine DXA (χ 2=193.557, P<0.001), hip DXA (χ 2=322.201, P<0.001) and dual-site DXA (χ 2=94.683, P<0.001), and the difference was statistically significant. Taking the diagnostic results of spinal DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 79%, a specificity of 81%, and an AUC and 95% CI of 0.82(0.79, 0.85). Taking the diagnostic results of hip DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 85%, a specificity of 55%, and an AUC and 95% CI of 0.75(0.71, 0.78). Taking the diagnostic results of two-site DXA for osteoporosis as a reference, the ROC curve of PL-QCT for the diagnosis of osteoporosis showed a sensitivity of 72%, a specificity of 75%, and an AUC and 95% CI of 0.81(0.78, 0.83). Conclusion:Compared with DXA, PL-QCT has a higher detection rate of osteoporosis in patients with degenerative lumbar spine disease and good diagnostic efficacy.

Objective:To assess the burden and development trends of tuberculosis (TB) in China from 1990 to 2021 to provide a reference for TB prevention strategies.Methods:Utilizing the 2021 Global Burden of Disease Study data, the study evaluates the burden of TB and latent TB infection (LTBI) in China using age-standardized incidence, prevalence, disability-adjusted life years (DALYs), and infection rates. The Joinpoint regression model was employed to analyze changing trends, and the autoregressive moving average model was integrated to forecast multidrug-resistant TB incidence and LTBI infection rates from 2022 to 2030.Results:In 2021, the age-standardized TB incidence in China was 36.28 per 100 000, the age-standardized prevalence was 30 557.45 per 100 000, the age-standardized DALY rate was 76.22 per 100 000, and the LTBI age-standardized infection rate was 30.48%. Compared to 1990, these figures dropped by 66.72%, 2.82%, 89.41%, and 2.47%, respectively. The age-standardized incidence, prevalence, DALY rate, and infection rate were elevated in individuals aged ≥70 years, and the TB burden was greater in males than in females. The age-standardized TB incidence declined between 1990 and 2021, while the proportion of multidrug-resistant TB patients among newly diagnosed cases, nationwide rose from 3.11% (36 367/1 167 807) in 1990 to 4.12% (25 431/617 725) in 2021. The LTBI age-standardized infection rate exhibited a fluctuating declining trend, averaging a decrease of 0.09%. Predictions for 2022-2030 indicate that China's multidrug-resistant TB incidence will decline slowly, and the LTBI infection rate will initially rise and then gradually fall, reaching 1.10/100 000 and 31.11%, respectively, by 2030.Conclusions:The TB burden in China declined from 1990 to 2021, but TB prevalence and LTBI infection rates remain high, especially among multidrug-resistant cases, males, and the elderly. Implementing systematic LTBI interventions, enhancing early detection/diagnosis in key populations such as the elderly, and promoting short-course treatments are recommended.

Objective:To determine the clinical issues in the Clinical practice guidelines for postoperative pain management in adults (2024 edition). Methods:A preliminary list of clinical issues for the guidelines was developed through literature review, clinical surveys, and expert interviews. This was followed by two rounds of Delphi questionnaire surveys, with quality control and statistical analysis conducted using expert positive coefficient, mean item scores, full score ratio, coefficient of variation, Cronbach′s α coefficient, and expert authority level to finalize the list of clinical issues.Results:The experts participating in the Delphi questionnaire surveys had multidisciplinary collaborative backgrounds and regional representativeness, with a high level of authority. The overall positive coefficient of expert participation in the surveys was 78.9%. Through two rounds of the Delphi method and based on the screening criteria of a mean score ≥3.5, coefficient of variation ≤30%, and full score ratio ≥30%, 17 clinical issues were ultimately included following an expert consensus meeting.Conclusions:Through the Delphi method and rigorous quality control, the clinical issues in the Clinical practice guidelines for postoperative pain management in adults (2024 edition) are determined, laying a foundation for the subsequent development of the guidelines.

Objective:To evaluate the association between body temperature and duration of mechanical ventilation in the intensive care unit (ICU) among patients after coronary artery bypass grafting (CABG).Methods:Clinical data from patients, aged >18 yr, undergoing primary isolated CABG, between 2008 and 2019, were extracted from the Medical Information Mart for Intensive Care Ⅳ version 2.0 database. Participants were stratified into 3 groups based on the mean body temperature in ICU: hypothermia group (<36.0 ℃), normothermia group (36.0 ℃ ≤ temperature <37.3 ℃), and hyperthermia group (≥37.3 ℃). Multivariable linear regression and linear curve fitting were performed to assess the association between body temperature and duration of mechanical ventilation.Results:A total of 4, 588 patients were finally included in the statistical analysis, including 133 cases in hypothermia group, 4, 177 cases in normothermia group and 278 cases in hyperthermia group. The duration of mechanical ventilation was significantly prolonged in both hypothermia and hyperthermia groups compared with normothermia group ( P<0.05). The results of multivariable linear regression demonstrated that each 1 ℃ increase in body temperature was associated with a 2.43 h reduction in the duration of mechanical ventilation in hypothermia group ( P<0.001), and each 1 ℃ temperature elevation corresponded to a non-significant reduction of 0.12 h in hyperthermia group ( P=0.851). The results of linear curve fitting revealed a U-shaped relationship between body temperature and duration of mechanical ventilation, and an inflection point was identified at 36.71 ℃, with duration of mechanical ventilation prolonged with temperatures either below or above this threshold ( P<0.05). Conclusions:Hypothermia during ICU stay following CABG may lead to prolonged mechanical ventilation in patients.

Objective:To evaluate the effectiveness of fosaprepitant in preventing postoperative nausea and vomiting (PONV) following gynecological laparoscopic surgery.Methods:In this randomized parallel-controlled trial, 100 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-64 yr, undergoing elective gynecological laparoscopic surgery under general anesthesia at the First Affiliated Hospital of Zhengzhou University, were selected and divided into 2 groups ( n=50 each) in a ratio of 1∶1 using blocked randomization: fosaprepitant group (group F) and tropisetron group (group T). At 30 min before anesthesia induction, fosaprepitant 150 mg was intravenously infused in group F, and tropisetron 5 mg was intravenously infused in group T, both diluted in 150 ml of normal saline. Anesthesia was induced by intravenous injection of midazolam, etomidate, sufentanil and cisatracurium. Anesthesia was maintained by intravenous infusion of remifentanil and propofol. Patient-controlled intravenous analgesia was performed with hydromorphone at the end of operation until 48 h after operation. Metoclopramide was given as rescue antiemetic. The PONV, requirement for antiemetic drugs and related adverse reactions were recorded within 24 h after surgery. Results:The incidence of PONV (10% vs 30%), the incidence of vomiting(2% vs 16%) and the rescue rate of antiemetic drugs(2% vs 12%)were significantly lower in group F than in group T ( P<0.05). There was no significant difference in the incidence of related adverse reactions between the two groups ( P>0.05). Conclusions:Intravenous infusion of fosaprepitant 150 mg at 30 min before anesthesia induction effectively prevents PONV in patients undergoing gynecological laparoscopic surgery, and the efficacy is superior to that of the conventional use of tropisetron.
