Objective To analyze the relationship between cognitive function, motor ability and the risk of falls in patients during the rehabilitation period after stroke. Methods A total of 330 patients with stroke who received rehabilitation treatment in the hospital from February 2022 to February 2025 were classified into fall group (n=105) and non-fall group (n=225) based on the occurrence of falls during rehabilitation period. The clinical data of patients were collected, and the motor function of patients was evaluated by Fugl-Meyer scale, and the cognitive function of patients was assessed by mini-mental state examination (MMSE). Univariate and logistic multivariate regression analyses were applied to analyze the factors affecting the occurrence of falls. Spearman correlation analysis was performed to analyze the relationship between motor ability, cognitive function and risk of falls. Results The proportions of osteoporosis, malnutrition, sleep disorder and history of falls in the fall group were higher while the education level, Fugl-Meyer score and MMSE score were lower compared to the non-fall group (P<0.05). After logistic multivariate analysis, it was found that osteoporosis, malnutrition, sleep disorder, history of falls, low education level, low Fugl-Meyer score and low MMSE score were risk factors for falls in patients during post-stroke rehabilitation period (P<0.05). Correlation analysis indicated that the motor ability and cognitive function in patients during post-stroke rehabilitation period were negatively associated with the occurrence of falls (r=-0.579, -0.438, P<0.001). Conclusion The cognitive function, motor ability of patients in the post-stroke rehabilitation period are closely related to the risk of falls. Clinically, the risk of falls in patients during post-stroke rehabilitation period can be reduced by improving the motor ability and cognitive function.

Based on the theory of circulation of qi,a theoretical model of the circulation of phase fire in the human body was con-structed.It is proposed that cancer toxicity is the key factor that triggers the disorder of phase fire and hinders the circulation of phase fire.The disorder of phase fire and poor circulation are important pathogenesis of the occurrence and development of cancer toxicity.With the principle of strengthening healthy qi and eliminating evil qi,the Wenzi Jiedu method is used to treat tumors,which plays an important role in warming and nourishing,regulating yin and yang,and eliminating cancer toxicity.The combination of war-ming,nourishing and detoxification can promote the return of the phase fire and make the human body's generation and transformation active,providing a new treatment idea for TCM diagnosis and treatment of tumors with mainly cold poison or mixed cold and heat.

OBJECTIVE To investigate the potential mechanism of Sanqi danshen tablets in the treatment of non-alcoholic fatty liver disease （NAFLD）. METHODS Core targets of Sanqi danshen tablets in the treatment of NAFLD were explored by network pharmacological methods. Gene ontology （GO） functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were also performed. Based on the results obtained from network pharmacological studies， using SD rats as subjects， the NAFLD model was induced by feeding them high-fat diet. The effects of Sanqi danshen tablets on pathological changes such as lipid droplet vacuoles and lipid accumulation in the liver tissue of NAFLD rats， as well as its impact on relative indicators of lipid metabolism， inflammatory responses and oxidative stress， were investigated. RESULTS A total of 20 core targets for the treatment of NAFLD with Sanqi danshen tablets were screened， primarily involved in GO functions such as biological regulation， cellular membrane and binding， and enriched in signaling pathways related to inflammatory responses， oxidative stress and lipid metabolism. Compared with the model group， lipid droplet vacuoles were reduced significantly in low-dose， medium-dose， high-dose groups of Sanqi danshen tablets and positive control （simvastatin） group， the number of lipid droplets decreased significantly and the color became lighter. The contents of total cholesterol， triglyceride （except for medium- dose group of Sanqi danshen tablets）， aspartate transaminase， alanine transaminase， tumor necrosis factor-α （except for low-dose group of Sanqi danshen tablets）， interleukin-17 （except for Sanqi danshen tablets groups） and malondialdehyde （except for low- dose group of Sanqi danshen tablets） in liver tissue were significantly decreased， while the content of superoxide dismutase was significantly increased （P＜0.01 or P＜0.05）. CONCLUSIONS Sanqi danshen tablets exert anti-inflammatory， antioxidant and lipid metabolism regulating effects by influencing the levels of inflammation， oxidative stress and lipids metabolism-related indicators， thereby improving NAFLD in rats.

Colorectal cancer is a malignant tumor that originates from the epithelial cells of the colon and rectum. It has the third highest incidence and the second highest mortality rate among malignant tumors worldwide. With the rapid development of the economy and the increasing Westernization of dietary habits in China， its incidence in China has been rising year by year. Over the past decade， despite the introduction of numerous treatment methods for colorectal cancer， the efficacy of existing therapies remains unsatisfactory. In recent years， traditional Chinese medicine （TCM） has become a major focus in the treatment of colorectal cancer due to its advantages of multi-target， multi-pathway mechanisms and low toxicity and side effects. Vascular endothelial growth factor （VEGF） is an important angiogenic factor that promotes blood vessel formation， providing nutrients and oxygen for tumor growth. It also increases vascular permeability， allowing tumor cells to easily pass through the blood vessel wall into other tissues， thereby facilitating metastasis. Several studies have shown that TCM can inhibit tumor angiogenesis and lymphangiogenesis， promote tumor cell apoptosis， and inhibit the proliferation of colorectal cancer cells by acting on the VEGF signaling pathway， thereby delaying tumor growth. In recent years， research in this field has been rapidly updated， but there is a lack of relevant summaries， making subsequent literature searches inconvenient. Therefore， this article focuses on the physiological functions of the VEGF signaling pathway， its role in the occurrence of colorectal cancer， and the intervention of TCM on VEGF， providing a supplement and summary of relevant information to offer a reference for future research in this area.

Idiopathic oligoasthenospermia （IO） has been increasingly emphasized in the diagnosis and treatment of male infertility. Oxidative stress damage directly affects sperm quality and spermatogenesis， constituting a major causative factor of IO. Firstly， due to its high content of polyunsaturated fatty acids， the sperm plasma membrane is highly sensitive to reactive oxygen species （ROS）， leading to lipid peroxidation accumulation and even inducing ferroptosis. Secondly， deficient downstream key proteins in the base excision repair pathway render sperm unable to repair extensive DNA oxidative damage under oxidative stress. Simultaneously， under oxidative stress， the apoptotic pathway of sperm is cascade-activated， causing rapid loss of motility. ROS further disrupts the hypothalamic-pituitary-gonadal axis， inhibiting testosterone production and ultimately affecting spermatogenesis. Wuzi Yanzongwan，in line with traditional Chinese medicine theory of treating IO through "nourishing kidney essence and harmonizing Yin and Yang"， clinically demonstrates its ability to improve sperm morphology， count， and motility， thereby enhancing male fertility. The research on the pharmacological constituents of Wuzi Yanzongwan primarily involves establishing a characteristic spectrum of Chinese medicine to achieve quality control and exploring the pharmacology of effective components. Studies have found that its main active ingredients consist of flavonoids and phenylpropanoids. Specifically， compounds such as hyperin， acteoside， kaempferol， and schisandrin A are identified as the primary active substances and quality control components. These compounds exhibit strong antioxidant activity and have been partly applied in research related to reproductive endocrine disorders. Tripterygium glycoside is primarily used for modeling of oxidative stress-induced IO. It leads to the accumulation of various lipid peroxides in testicular tissues and concurrently compromises the body's antioxidant capacity. Mechanistic studies have found that Wuzi Yanzongwan can inhibit elevated ROS levels in IO models and enhance the body's antioxidant capacity， thereby ameliorating inflammation， suppressing cell apoptosis， promoting testosterone production， and ultimately alleviating the decline in sperm quality and spermatogenesis caused by oxidative stress.

BACKGROUND:The temporal and spatial expression of fibroblast growth factor receptors 1 and 2 remains a controversial issue during kidney development,so the relationship between them and kidney development remains unclear. OBJECTIVE:To observe the dynamic expression of fibroblast growth factor receptors 1 and 2 during kidney development of mice,and to investigate the relationship between them and kidney development. METHODS:The kidneys of fetal mice[embryotic days(E)12,14,16,and 18]and neonatal mice[neonatal days(N)1,3,7,14,24,and 40]were selected to examine the temporal and spatial expression of fibroblast growth factor receptors 1 and 2 by immunohistochemistry method in kidney tissues,and quantitative analysis was performed using western blot assay. RESULTS AND CONCLUSION:(1)Immunohistochemistry showed that fibroblast growth factor receptor 1 was mainly localized in metanephric tissue surrounding the tip of the ureteral bud at E12.Subsequently,fibroblast growth factor receptor 1 was expressed in immature renal corpuscles at various stages,some distal convoluted tubules and capillary loops.The positive site was mainly concentrated in the generative region.Fibroblast growth factor receptor 2 was initially expressed in both ureteral buds and metanephric tissue.Fibroblast growth factor receptor 2 was localized in immature renal corpuscles,distal tubules,collecting ducts and thin segments of medullary loops with kidney development.However,the expression of renal corpuscles was weak.(2)Stereology and western blot assay showed that the expression of fibroblast growth factor receptor 1 was high before birth and gradually decreased after birth,while the expression was very low after N7 day.The expression level of fibroblast growth factor receptor 2 increased gradually with the kidney development and tended to be stable after N7 day.(3)The results exhibit that fibroblast growth factor receptors 1 and 2 are expressed spatially and temporally during kidney development.It is speculated that fibroblast growth factor receptors 1 and 2 may influence nephron development and maturation,and fibroblast growth factor receptor 2 is critical during the formation of ureteral buds and morphology.

This study aims to investigate the protective effect of resveratrol against liver injury in hindlimb unloading rats. Thirty 2-month-old male SD rats were randomly divided into normal group (Control), hindlimb unloading model group (Model), and hindlimb unloading+resveratrol administration group (Model+Res). The Model + Res group was injected intraperitoneally with 30 mg/kg of resveratrol, and the Control and Model groups were injected intraperitoneally with an equal volume of 0.9% NaCl. Liver tissues were collected after 28 days and analyzed for oxidative stress, inflammatory factors, energy metabolism indices, Na ⁺-K ⁺-ATPase and Ca ²⁺-Mg ²⁺-ATPase activity, and morphological changes were observed by hematoxylin-eosin staining. The protein expression levels of Bax, Bcl-2, p-PI3K, PI3K, p-AKT, and AKT were detected by Western blotting. Compared with the Control group, hepatocytes in the Model group showed swelling, abnormal morphology, nuclear consolidation, and cell membrane disruption. Oxidative stress, inflammatory factor levels, hepatic glycogen accumulation, and energy metabolism were increased in the liver tissues of the Model group, while resveratrol treatment significantly reversed these changes. The results of Western blotting showed that resveratrol significantly reduced the expression of Bax and increased the expression levels of Bcl-2, and the proteins of p-PI3K/PI3K and p-AKT/AKT expression levels. It is suggested that 28 days of hindlimb unloading treatment could lead to liver tissue injury in rats, which is manifested as oxidative stress, inflammatory response, energy metabolism disorder and increased apoptosis level, and resveratrol has a certain mitigating effect on this.
