Objective:To study the CT and MRI features of xanthogranulomatous cholecystitis (XGC).Methods:Clinical data of 41 patients with XGC admitted to Yueqing Third People's Hospital, Yueqing People's Hospital and Wenzhou Central Hospital from January 1, 2013 to December 30, 2023 were retrospectively analyzed, including 21 males and 20 females, aged 63 (61, 65) years. Data including gender, age, clinical manifestations, CT and MRI features, were recorded.Results:Of the 41 patients, 26 had clinical manifestations of upper abdominal pain accompanied by nausea, vomiting, and fever, and 15 had upper abdominal pain accompanied by jaundice. Forty-one patients had positive percussion pain in liver area, of which 18 had positive Murphy’s sign and 12 had jaundice of the skin and sclera. Among the 25 patients who underwent CT examination, the gallbladder had a longitudinal diameter of 8 (5, 10) cm and a transverse diameter of 4 (3, 6) cm. The thickness of the thickened gallbladder wall was 1.6 (0.4, 1.9) cm. Most cases show diffuse uneven thickening, and a few cases show uniform diffuse or localized thickening. After enhancement, the thickened gallbladder wall can be seen as " sandwich" - or " sandwich cookie" -like enhancement or layered enhancement. Mucosal line is continuous or discontinuous. Eleven cases with low-density nodules between walls showed no enhancement. Among the 16 patients who underwent routine MRI examinations, the gallbladder had a longitudinal diameter of 8 (5, 10) cm and a transverse diameter of 4 (3, 6) cm. The thickness of the thickened gallbladder wall was 1.6 (0.4, 1.9) cm. Most cases show diffuse uneven thickening, and a few cases show uniform diffuse or localized thickening. There were nine cases of multiple small nodules between walls. The thickened gallbladder wall showed heterogeneous signal on T 1-weighted imaging (T 1WI) and T 2-weighted imaging (T 2WI), presenting equal, high, low, or mixed signals. T 1WI showed low signal intensity in reverse phase. Diffusion weighted imaging fat suppression sequence shows multiple small nodules within the wall with high signal intensity. Nine cases of intramural nodules showed high signal intensity on T 1WI in-phase, T 2WI, and T 2WI fat phase, low signal intensity on T 1WI in-phase, and low signal intensity on T 2WI fat suppression sequence. The wall of gallbladder showed " sandwich" - or " sandwich cookie" -like enhancement or layered enhancement. Mucosal line is continuous or discontinuous. Nine cases of intramural nodules showed no enhancement. Conclusions:The CT and MRI features of XGC are diffuse and uneven thickening with nodules between the gallbladder walls in most cases. Nodules with low density on CT plain scan, high signal on T 1WI in-phase, high signal on T 2WI, and low signal on T 1WI out-phase. The thickening of the gallbladder wall after enhancement is characterized by a " sandwich" - or " sandwich cookie" -like enhancement.

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 explore the temporal characteristics and correlation between active exercise rehabilitation behaviour and related symptoms in middle-aged chronic obstructive pulmonary disease(COPD)patients,and to provide a basis for constructing a full cycle precision rehabilitation management system.Methods The ecological momentary assessment method was used to select 63 middle-aged COPD patients from the respiratory and critical care medicine department of a tertiary comprehensive hospital in Wuhan from October 15 to December 1,2024,using convenience sampling.Their active exercise rehabilitation behaviour(number of exercise projects,duration)and related symptoms(dyspnea,fatigue,anxiety)were continuously monitored for a week by using baseline survey,daily active exercise rehabilitation behavior assessment questionnaire,daily symptom assessment questionnaire.A multi-layer linear model was used to analyze the dynamic correlation between active exercise rehabilitation behaviour and symptoms.Results 58 patients were included.During the 1-week ecological momentary assessment,the system triggered a total of 1,218 momentary assessments and obtained 1,120 valid responses(with the valid response rate of 91.95％),with patients completing an average of(2.76±0.39)assessments per day.Multilevel linear models showed that momentary dyspnoea,fatigue,anxiety symptoms and baseline kinesiophobia all significantly negatively influenced active exercise rehabilitation behaviour(P＜0.05).Conclusion There are dynamic changes in the active exercise rehabilitation behaviour and related symptoms of middle-aged COPD patients.Nursing staff should establish a precise rehabilitation intervention system based on symptom fluctuations,strengthen patient self-management efficiency through dynamic monitoring and hierarchical management,and achieve long-term optimization of lung rehabilitation effects.

Objective To investigate the correlation between the expression of microRNA-4319(miRNA-4319)and microRNA-4262(miRNA-4262)in early gastric carcinoma tissue and postoperative recurrence after endoscopic submucosal dissection(ESD).Methods From May 2018 to March 2020,396 patients with early gastric carcinoma who underwent ESD were regarded as the disease group,meantime,98 patients with normal gastric mucosa gastritis confirmed by pathological examination were as the control group.Quantitative reverse transcription polymerase chain reaction(qRT-PCR)method was applied to detect the relative expression levels of miRNA-4319 and miRNA-4262 in tissues;follow up on postoperative recurrence of early gastric carcinoma patients,and the expression levels and clinical pathological characteristics of miRNA-4319 and miRNA-4262 were compared between recurrent and non recurrent patients.Multivariate Logistic regression analysis was applied to analyze the influencing factors of recurrence in early gastric carcinoma patients after ESD;receiver operating characteristic curve(ROC curve)was applied to analyze the predictive value of miRNA-4319 and miRNA-4262 in early gastric carcinoma tissue for recurrence after ESD.Results The expression levels of miRNA-4319 and miRNA-4262 in the disease group were lower than those in the control group,the differences were statistically significant(P＜0.05);The expression levels of miRNA-4319 and miRNA-4262 in the recurrence group were decreased,and the proportion of submucosal invasion was increased,the differences were statistically significant(P＜0.05).The depth of invasion to the submucosal level(OR=3.158,95％CI:1.395～7.151)was a risk factor for recurrence after ESD in patients with early gastric carcinoma(P＜0.05),and miRNA-4262 ≥ 0.76(OR=0.561,95％CI:0.370～0.852)and miRNA-4319 ≥ 0.69(OR=0.482,95％CI:0.255～0.911)were protective factors for recurrence after ESD in patients with early gastric carcinoma(P＜0.05);The area under the curve(AUC)of miRNA-4319,miRNA-4262 and their combination for predicting recurrence after ESD in patients with early gastric carcinoma was 0.889(95％CI:0.854～0.918),0.914(95％CI:0.882～0.940)and 0.964(95％CI:0.940～0.980),respectively,which was superior to the individual predictions of miRNA-4319 and miRNA-4262 respectively(P＜0.05).Conclusion MiRNA-4319 and miRNA-4262 are low expressed in tissues of early gastric carcinoma patients,they are closely related to postoperative recurrence after ESD.
