By systematically combing ancient and modern literature， this paper examined Tribuli Fructus and Astragali Complanati Semen（ACS） used in the famous classical formulas from the aspects of name， origin， production area， harvesting and processing， clinical efficacy， so as to provide a basis for the development of famous classical formulas containing such medicinal materials. The results showed that the names of Tribuli Fructus in the past dynasties were mostly derived from its morphology， and there were nicknames such as Baijili， Cijili and Dujili. The name of ACS in the past dynasties were mostly originated from its production areas， and there were nicknames such as Baijili， Shayuan Jili and Tongjili. Because both of them had the name of Baijili， confusion began to appear in the Song dynasty. In ancient and modern times， the main origin of Tribuli Fructus were Tribulus terrestris， and ancient literature recorded the genuine producing areas of Tribuli Fructus was Dali in Shaanxi and Tianshui in Gansu， but today it is mainly cultivated in Anhui and Shandong. The fruit is the medicinal part， harvested in autumn throughout history. There is no description of the quality of Tribuli Fructus in ancient times， and the plump， firm texture， grayish-white color is the best in modern times. Traditional processing methods for Tribuli Fructus included stir-frying and wine processing， while modern commonly used is purified， fried and salt-processed. The ancient records of Tribuli Fructus were spicy， bitter， and warm in nature， with modern research adding that it is slightly toxic. The main effects of ancient and modern times include treating wind disorders， improving vision， promoting muscle growth， and treating vitiligo. The mainstream base of ACS used throughout history is Astragalus complanatus. Ancient texts indicated ACS primarily originated from Shaanxi province. Today， the finest varieties come from Tongguan and Dali in Shaanxi. The medicinal part is the seed， traditionally harvested in autumn. Modern harvesting occurs in late autumn or early winter， followed by sun-drying. Ancient texts valued seeds with a fragrant aroma as superior， while modern standards prioritize plump， uniform and free of impurities. Traditional processing methods for ACS included frying until blackened and wine-frying， while modern practice commonly employs purification methods. In terms of medicinal properties， the ancient and modern records are sweet and warm in nature. Due to originally classified under Tribuli Fructus， its effects were thus regarded as equivalent to those of Tribuli Fructus， serving as the medicine for treating wind disorders， additional functions included tonifying the kidneys and treating vitiligo. The present record of its efficacy is to tonify the kidney and promote Yang， solidify sperm and reduce urine， nourish the liver and brighten the eye， etc. Based on the textual research results， it is suggested that when developing the famous classical formulas of Tribuli Fructus medicinal materials， we should pay attention to the specific reference object of Baijili， T. terrestris and A. complanatus should be identified and selected， and the processing method should be in accordance with the requirements of the formulas.

OBJECTIVES: A ventricular assist device (VAD) is an electromechanical device used to assist cardiac blood circulation, which can be employed for the treatment of end-stage heart failure and is most commonly placed in the left ventricle. Despite enhancing perfusion performance, the implantation of left ventricular assist device (LVAD) transforms the local intraventricular flow and thus may increase the risk of thrombogenesis. This study aims to investigate fluid-particle interactions and thromboembolic risk under different LVAD configurations using three-dimensional (3D) reconstruction models, focusing on the effects of outflow tract orientation and blood flow rates. METHODS: A patient-specific end-diastolic 3D reconstruction model was initially constructed in stereo lithography (STL) format using Mimics software based on CT images. Transient numerical simulations were performed to analyze fluid-particle interactions and thromboembolic risks for LVAD with varying outflow tract orientations under 2 flow rates (4 L/min and 5 L/min), using particles of uniform size (2 mm), and a blood flow rate optimization protocol was implemented for this patient. RESULTS: When the LVAD flow rate was 5 L/min, helicity and flow stagnation of the blood flow increased the particle residence time (RT) and the risk of thrombogenesis of the aortic root. The percentage of particles traveling toward the brachiocephalic trunk was up to 20.33%. When the LVAD flow rate was 4 L/min, blood turbulence in the aorta was reduced, the RT of blood particles was shortened, and then the percentage of particles traveling toward the brachiocephalic trunk decreased to 10.54%. When the LVAD blood flow rate was 5 L/min and the direction of the outflow pipe was optimal, the RT of blood particles was shortened, and then the percentage of particles traveling toward the brachiocephalic trunk decreased to 11.22%. A 18-month follow-up observation of the patient revealed that the LVAD was in good working order and the patient had no complications related to the implantation of LVAD. CONCLUSIONS Implantation of LVAD results in a higher risk of cerebral infarction; When implanting LVAD with the same outflow tract direction, optimizing flow velocity and outflow tract can reduce the risk of cerebral infarction occurrence.

This study explored how the human cortical folding pattern composed of convex gyri and concave sulci affected single-subject morphological brain networks, which are becoming an important method for studying the human brain connectome. We found that gyri-gyri networks exhibited higher morphological similarity, lower small-world parameters, and lower long-term test-retest reliability than sulci-sulci networks for cortical thickness- and gyrification index-based networks, while opposite patterns were observed for fractal dimension-based networks. Further behavioral association analysis revealed that gyri-gyri networks and connections between gyral and sulcal regions significantly explained inter-individual variance in Cognition and Motor domains for fractal dimension- and sulcal depth-based networks. Finally, the clinical application showed that only sulci-sulci networks exhibited morphological similarity reductions in major depressive disorder for cortical thickness-, fractal dimension-, and gyrification index-based networks. Taken together, these findings provide novel insights into the constraint of the cortical folding pattern to the network organization of the human brain.

However, the efficacy and safety of anti-inflammatory therapy with colchicine in preventing recurrent stroke is unclear. This article reviews the relevant mechanisms of action of colchicine and its role in the prevention of ischemic stroke, aiming to provide reference for the secondary prevention of ischemic stroke.

Gravity is one of the most widespread mechanomechanical signals affecting surface organisms and plays a key role in maintaining normal cardiovascular structure and function.The absence of gravity in the space environment leads to changes in the physiological-mechanical environment of the cardiovascular system,potentially causing adaptive changes or remodelling of the cardiovascular system in terms of structure and function.However,how the cardiovascular system senses,transduces,and responds to altered mechanical stress in the microgravity environment remains poorly understood by humans.In this paper,we reviewed the research findings on mechanoreceptors and mechano-transduction of cardiovascular system in recent years,analyzed the mechanisms of mechanical perception and response to microgravity in cardiovascular system,and predicted the novel mechanoreceptors,key signaling pathways,and potential targets for intervention in space microgravity.This article aims to provide new ideas for combating adaptive changes in the cardiovascular system due to space microgravity.

Dura mater is a tough collagen connective tissue attached to inner surface of skull and wrapped around brain.As a buffer bridge between brain tissue and skull,its physiological function and role in skull development and repair have always been a focus of research.Recent studies have found that dura mater not only directly participates in skull development during skull growth,but also secretes a variety of cytokines that control the development of central nervous system.There are abundant material exchange and cell communication between the two.This article reviews the role of dura in development and repair of skull,and provides clues for further discovery of the relevant mechanisms of dura in development and repair of skull.

Objective:To explore the surgical treatment of lateral condylar fracture of the humerus combined with lateral dislocation of the elbow in adults.Methods:A retrospective study was conducted to analyze the 8 patients who had been treated at Department of Orthopaedic Trauma, Zhengzhou Orthopaedic Hospital for lateral condylar fracture of the humerus combined with lateral dislocation of the elbow from June 2020 to June 2023. There were 3 males and 5 females, with an age of (50.1±12.3) years. All the lateral condylar fractures of the humerus combined with lateral dislocations were treated by open reduction and internal fixation after swelling subsided. Flexion and extension of the elbow and rotation of the forearm were recorded at the last follow-up. Mayo elbow function score (MEPS) was used to evaluate the functional recovery of the elbow.Results:Elbow dislocation was corrected in 2 patients after rectification, but the elbow subluxation still existed because the displacement of the humeral lateral condyle was not reduced. The elbow dislocation still existed in 6 patients because it was difficult to maintain the correction of the dislocation after manual reduction. Follow-ups were conducted for 12.0 (12.0, 18.8) months. At the last follow-up, the flexion-extension was 85.6°±20.3°, rotation 133.1°±24.0°, and MEPS (91.9±8.0) points. The joint stability was significantly improved in the 8 patients compared with that before operation. Obvious pain was reported in none of the patients, and their joint limitation was acceptable.Conclusions:In adults, lateral condylar fracture of the humerus combined with lateral dislocation of the elbow is rare in clinic. Surgical treatment of the condition can achieve satisfactory clinical outcomes, but elbow dysfunction and limited rotation of the forearm may occur in the affected limb.
