The concept of"musculoskeletal imbalance with soft tissue primacy"posits that tendon injury induced by intervertebral disc degeneration constitutes the core pathogenesis of spinal musculoskeletal imbalance.This study systematically elucidates the pathological mechanisms through which tendon injury leads to spinal instability by integrating traditional Chinese medicine(TCM)"musculoskeletal balance"theory with contemporary biomechanical research on disc degeneration.In the process of intervertebral disc degeneration,the change of stress distribution revealed by modern biomechanics is highly consistent with the TCM principle of"tendon impairment affecting bone".Finite element analysis revealing the"stability-instability-restabilization"process further validates the pathological progression from musculoskeletal imbalance to rebalance.This integrated TCM-Western medicine perspective establishes a novel theoretical framework for predicting disease progression and developing personalized therapeutic strategies,particularly in guiding clinical practice of"treating bone disorders through tendon regulation".

Objective:To investigate the influencing factors and prognosis of early recurrence after gastrectomy for gastric cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 2 078 patients who underwent gastrectomy for gastric cancer at six medical centers across China, including Fudan University Shanghai Cancer Center et al, between January 2012 and June 2023 were collected. There were 1 449 males and 629 females, aged (59±11) years. Patients were classified as early recurrence and late recurrence based on the time of post-operative recurrence. Observation indicators: (1) comparison of clinicopathological characteristics between gastric cancer patients with different recurrence types; (2) recurrence and metastasis of tumor; (3) survival of patients after postoperative recurrence of gastric cancer; (4) analysis of influencing factors for early recurrence after gastrectomy for gastric cancer. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the rank sum test. Multivariate analysis was conducted using the Logistic regression model. Kaplan-Meier method was used to calculate survival rate and plot survival curve, and Log-rank test was used for survival analysis. Results:(1) Comparison of clinicopathological characteristics between gastric cancer patients with different recurrence types. Among the 2 078 patients, 1 452 cases had early recurrence and 626 cases had late recurrence. There were significant differences in preoperative carcinoembryonic antigen, preoperative CA19-9, preoperative CA72-4, preoperative albumin, tumor diameter, neoadjuvant therapy, R 0 resection, combined organ resection, scope of gastric resection, nerve and vessel infiltration, degree of tumor differentiation, pathological N staging, pathological TNM staging between early and late recurrence patients ( P<0.05). (2) Recurrence and metastasis of tumor. Among the 2 078 patients, 200 cases had local recurrence, 1 213 cases had hematogenous metastases, 392 cases had distant lymph node metastases, and 731 cases had peritoneal metastases. Among the 1 452 early recurrence patients, 142 cases had local recurrence, 834 cases had hematogenous metastases, 289 cases had distant lymph node metastases, and 507 cases had peritoneal metastases. Among the 626 late recurrence patients, 58 cases had local recurrence, 379 cases had hematogenous metastases, 103 cases had distant lymph node metastases, and 224 cases had peritoneal metastases. One patient may have multiple forms of recurrence and metastasis. There was no significant difference in the above indica-tors between early and late recurrence patients ( χ2=0.13, 1.74, 3.40, 0.14, P>0.05). (3) Survival of patients after postoperative recurrence of gastric cancer. All 2 078 patients were followed up until death after recurrence, with a follow-up time of 31(range, 9?147)months. The 1-, 2-, 3-, and 5-year overall survival rates after recurrence were 33.5%, 17.2%, 10.1%, and 3.3% in early recurrence patients, versus 44.2%, 21.6%, 12.8%, and 5.8% in late recurrence patients, respectively, showing a significant difference in overall survival after recurrence between the two groups ( hazard ratio=0.84, 95% confidence interval as 0.76?0.92, P<0.05). (4) Analysis of influencing factors for early recurrence after gastrectomy for gastric cancer. Results of multivariate analysis showed that combined organ resection, total gastrectomy, pathological TNM staging as stage Ⅲ were independent risk factors for early recurrence after gastrectomy for gastric cancer ( odds ratio=1.31, 1.32, 1.34, 95% confidence interval as 1.01?1.70, 1.06?1.65, 1.05?1.71, P<0.05) and normal preoperative tumor markers, neoadjuvant therapy, R 0 resection were independent protective factors for early recurrence ( odds ratio=0.61, 0.50, 0.38, 95% confidence interval as 0.49?0.76, 0.35?0.72, 0.25?0.58, P<0.05). Conclusions:Compared with patients with late recurrence after gastric cancer surgery, patients with early recurrence have a poor prognosis, in which liver metastases is more common. Combine organ resection, total gastrectomy, pathological TNM staging as stage Ⅲ are independent risk factors for early recurrence, and normal preoperative tumor markers, neoadjuvant therapy, R 0 resection are independent protective factors for early recurrence after gastrectomy for gastric cancer.

Objective:To explore the characteristics of eosinophilic granulomatous polyangiitis (EGPA) and provide a basis for clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the epidemiology, clinical manifestations, laboratory tests, imaging and pathological characteristics, and treatment outcomes of 15 cases of eosinophilic granulomatous vasculitis.Results:Fifteen patients with eosinophilic granulomatous vasculitis were aged (50.7±17.2)years old, with a median time of 182.5 days from onset to diagnosis. Thirteen patients presented with respiratory symptoms as the initial diagnosis, while the other two presented with skin and nervous system damage. These patients were all accompanied by an increase in peripheral blood eosinophils, fluctuating between 10.6% and 60.94%. Thirteen patients had respiratory symptoms, mainly cough, sputum production, shortness of breath, and varied chest computed tomography (CT) findings. Histopathology or alveolar lavage fluid also showed changes in eosinophil count.Conclusions:The clinical manifestations of eosinophilic granulomatous vasculitis are diverse, often involving the respiratory system, as well as multiple systems such as the circulatory system, digestive system, nervous system, urinary system, and skin. However, due to its frequent early manifestations of wheezing, it is often misdiagnosed as refractory asthma. Improving the understanding of eosinophilic granulomatous vasculitis and improving the level of early diagnosis can help improve the prognosis of patients.

Improving the reproducibility of biomedical research results is a major challenge.Researchers reporting their research process transparently and accurately can help readers evaluate the reliability of the research results and further explore the experiment by repeating it or building upon its findings. The ARRIVE 2.0 guidelines, released in 2019 by the UK National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs), provide a checklist applicable to any in vivo animal research report. These guidelines aim to improve the standardization of experimental design, implementation, and reporting, as well as the reliability, repeatability, and clinical translatability of animal experimental results. The use of ARRIVE 2.0 guidelines not only enriches the details of animal experimental research reports, ensuring that information on animal experimental results is fully evaluated and utilized, but also enables readers to understand the content expressed by the author accurately and clearly, promoting the transparency and integrity of the fundamental research review process. At present, the ARRIVE 2.0 guidelines have been widely adopted by international biomedical journals. This article is a Chinese translation based on the best practices of international journals following the ARRIVE 2.0 guidelines in international journals, specifically for the complete interpretation of the ARRIVE 2.0 guidelines published in the PLoS Biology journal in 2020 (original text can be found at https://arriveguidelines.org). The third part of the article includes the items 8-10 of ARRIVE 2.0 Essential 10, which covers "experimental animals" "experimental procedures" and "results". Its aim is to promote the full understanding and use of the ARRIVE 2.0 guidelines by domestic researchers, enhance the standardization of experimental animal research and reporting, and promote the high-quality development of experimental animal technology and comparative medicine research in China.

ObjectiveTo study the effect on quality of life and the bone turnover markers of Buzhong Yiqitang in the treatment of senile osteoporotic vertebral compression fracture （OVCF， syndrome of Qi deficiency in spleen and stomach） after operation based on ''spleen governing muscle''. MethodA total of 135 senile patients with OVCF treated by percutaneous kyphoplasty in Rizhao Hospital of Traditional Chinese Medicine from January 2020 to January 2021 were enrolled in this study. They were randomly assigned to two groups on the basis of block randomization at a ratio of 2∶1 （90 cases in the observation group and 45 cases in the control group）. Both groups were administrated with calcitriol capsules （0.5 μg·d^-1） and caltrate D （1 200 mg·d^-1） for basic treatment of osteoporosis. The observation group was additionally treated with Buzhong Yiqitang. Bone mineral density （BMD）， procollagen type Ⅰ N-terminal propeptide （PINP）， osteocalcin （OST）， β cross-linked C-telopeptide of type 1 collagen （β-CTx）， appendicular skeletal muscle mass index （ASMI）， and quadriceps muscle strength were compared between the two groups before and 6， 12 months after treatment. Additionally， traditional Chinese medicine （TCM） symptom score and visual analogue score （VAS） before and 3， 6 months after treatment， as well as quality of life questionnaire of the European Foundation for osteoporosis （QUALEFFO） score before and 3， 6， 12 months after treatment， were compared between the two groups. ResultA total of 85 patients in the observation group and 41 patients in the control group were followed up. The general curative effect of the observation group was better than that of the control group （χ²=10.503， P<0.05）. Specifically， the observation group had higher PINP， BMD， ASMI， and quadriceps muscle strength but lower β-CTx， TCM symptom score， VAS， and QUALEFFO score than the control group （P<0.05， P<0.01）. No adverse reactions related to Buzhong Yiqitang were observed. ConclusionBuzhong Yiqitang can regulate bone metabolism indexes， promote osteogenesis， increase bone density， enhance skeleton appendiculare and quadriceps muscle strength， relieve clinical symptoms， and improve quality of life in patients with senile OVCF （syndrome of Qi deficiency in spleen and stomach）， being worthy of promotion in clinical application.

Objective:To investigate the clinical significance of MRI dynamic enhancement in defining the upper edge of adenocarcinoma of esophagogastric junction.Methods:The clinical data of 73 patients with adenocarcinoma on the esophagogastric junction operated from Jul 2018 to Aug 2019 in the Affiliated Cancer Hospital of Zhengzhou University were retrospectively analyzed. All patients underwent MRI examination within one week before surgery. First, the T 2WI, diffusion-weighted imaging and dynamic enhanced images of each patient were carefully observed to define the tumor location, size, shape, signal and enhancement mode, then the distances between the upper edge of the tumor and the cardiac incisure on MRI dynamic enhancement were measured independently, and compared with the measured distance in surgical fresh specimens. Results:The mean location of tumor upper edge measured in MRI of 73 patients was (1.75±1.98)cm, while measured in the surgical specimen was (1.72±1.97)cm. There was no significant difference between the two groups ( t=0.572, P=0.569). The intraclass correlation efficient between the two groups was excellent (ICC=0.974, 95% CI: 0.959-0.984, P<0.01). Conclusion:The measurement result of tumor upper edge in MRI is basically consistent with that of surgical specimens. MRI can be used to locate the tumor upper edge for adenocarcinoma of esophagogastric junction before operation.
