Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Traditional Chinese medicine(TCM)exerts integrative effects on complex diseases owing to the char-acteristics of multiple components with multiple targets.However,the syndrome-based system of diagnosis and treatment in TCM can easily lead to bias because of varying medication preferences among physicians,which has been a major challenge in the global acceptance and application of TCM.Therefore,a standardized TCM prescription system needs to be explored to promote its clinical application.In this study,we first developed a gradient weighted disease-target-herbal ingredient-herb network to aid TCM formulation.We tested its efficacy against intracerebral hemorrhage(ICH).First,the top 100 ICH targets in the GeneCards database were screened according to their relevance scores.Then,SymMap and Traditional Chinese Medicine Systems Pharmacology(TCMSP)databases were applied to find out the target-related ingredients and ingredient-containing herbs,respectively.The relevance of the resulting ingredients and herbs to ICH was determined by adding the relevance scores of the corresponding targets.The top five ICH therapeutic herbs were combined to form a tailored TCM prescriptions.The absorbed components in the serum were detected.In a mouse model of ICH,the new prescription exerted multifaceted effects,including improved neurological function,as well as attenuated neuronal damage,cell apoptosis,vascular leakage,and neuroinflammation.These effects matched well with the core pathological changes in ICH.The multi-targets-directed gradient-weighting strategy presents a promising avenue for tailoring precise,multipronged,unbiased,and standardized TCM prescriptions for complex diseases.This study provides a paradigm for advanced achievements-driven modern innovation in TCM concepts.

Objective To investigate the correlations of computed tomography (CT), clinical, and pathological features in patients with invasive lung adenocarcinoma positive and negative for spread through air spaces (STAS). Methods A total of 236 patients with invasive lung adenocarcinoma confirmed by surgery and pathology were selected, including 118 patients in STAS-positive group and 118 patients in STAS-negative group. The clinical data, CT signs, and pathological features of the two groups were collected and analyzed. Results There was a correlation between age and the occurrence of STAS. The age of the positive group was higher than that of the negative group. Smoking history and family history of tumor had no correlation with the occurrence of STAS. CT features signs such as nodule type and shape, tumor-lung interface, lobulation sign, spiculation sign, vacuole/cavity, air-bronchogram, pleural indentation sign, vascular changes, mean diameter of tumor, mean diameter of solid component, and the percentage of tumor solid components were significantly different between patients with and without STAS. The incidence of STAS in patients with solid nodules and partial solid nodules was significantly higher than that in patients with ground glass nodules. Multivariate analysis showed that the percentage of tumor solid components, air-bronchogram sign, lobulation sign, and tumor-lung interface were independent risk factors for predicting the occurrence of STAS. Conclusion The clinical data and CT signs of patients with invasive lung adenocarcinoma are related to the occurrence of STAS. CT signs such as the percentage of tumor solid components, air-bronchogram, lobulation sign, and tumor-lung interface are of great significance to STAS prediction. Our findings provide an important basis for selection of personalized clinical treatment plans.

The incidence of psycho-cardiological diseases， i.e.， cardiovascular diseases combined with psychological disorders， is increasing year by year. Brain-derived neurotrophic factor （BDNF） plays a role in the pathogenesis of such diseases. According to the theory of collateral diseases， our team innovates the concept of regulating mental activity by dredging collaterals in the treatment of psycho-cardiological diseases and summarizes the concepts of "heart of Qi and collaterals" and "heart of vessels and collaterals". We believe that obstructed collaterals and disturbed mental activity run through the whole course of psycho-cardiological diseases， being the core pathogenesis. BDNF closely related to the core pathogenesis can regulate nerve and vascular inflammation， alleviate oxidative stress， and mediate a variety of signaling pathways， thereby promoting the survival and repair of nerve cells and vascular endothelial cells to regulate emotion and protect the heart. Therefore， BDNF is one of the potential biomarkers for clinical treatment of psycho-cardiological diseases. Collateral obstruction caused by blood stasis is specifically manifested as collateral deficiency， blood stasis， and Qi stagnation in collaterals. It can easily lead to inflammation， free radical generation， and antioxidant system changes in the patients with psycho-cardiological diseases， which can cause oxidative stress damage， affect the BDNF level， and result in mental disorders， such as anxiety and depression. Disturbed mental activity is mainly caused by the disturbance in the heart of Qi and collaterals， which is specifically manifested as the disturbance of the mind and liver soul. It is prone to cause anxiety or depression symptoms， which is closely related to the BDNF-mediated abnormal activation of neural circuits， nerve injury， and inflammation. This article elaborates on the theoretical connotation and pathological mechanism of regulating mental activity by dredging collaterals in the treatment of psycho-cardiological diseases from the perspective of BDNF， aiming to provide new ideas for the prevention and treatment of psycho-cardiological diseases and collateral diseases.
