The oocyte， as the origin of life， provides half the chromosomes to the embryo and supplies the proteins， substrates， energy， and other support necessary for embryonic development. It is the decisive factor determining the embryo's developmental potential. Infertility caused by reproductive endocrine diseases targets the oocyte as the final target cell. Improving oocyte quality represents a key and difficult point in the field of modern reproductive medicine. The decline of oocyte quality is related to meiosis abnormalities， DNA damage， mitochondrial dysfunction， oxidative stress， and other mechanisms. For oocyte quality problems， there is no unified international guideline to recommend drugs. Because the drug intervention research on oocytes involves strict clinical ethical restrictions， the current relevant research only stays in the animal and in vitro experimental stage and has not yet been applied to the clinic. Traditional Chinese medicine compound formula has a multi-target and multi-pathway regulation mechanism and is widely used in clinics. More and more research began to pay attention to the potential mechanism of traditional Chinese medicine compound formulas in improving oocyte quality. Traditional Chinese medicine compound formula has the advantages of multi-target and multi-channel synergy as well as better safety， individualization， and conformity to clinical ethics in improving oocyte quality. This article systematically reviewed the research progress on traditional Chinese medicine compound formula interventions for oocyte quality， aiming to summarize existing findings and provide recommendations to improve oocyte quality and optimize the clinical diagnosis and treatment of female infertility within traditional Chinese medicine.

BACKGROUND:Arthroscopic anchor repair has become the main treatment method for rotator cuff tears at present.Among them,the insertion status of the anchor is a key factor in the success or failure of the operation.However,currently,the impact of the insertion depth of the anchor on the stress of the bone tunnel and the anchor under different bone density conditions remains unclear.OBJECTIVE:To explore the stress distribution of the bone tunnel and the anchor when the insertion depth of the anchor varies under different bone density conditions by using three-dimensional finite element analysis technology.METHODS:The CT image data of the humerus of volunteers were collected,and the models of the humerus and the anchor were constructed by using Mimics,3-Matic,and Solidworks software.In 3-Matic,holes with distances of 0,2,4,6,and 8 mm from the surface of the humerus were respectively created at the same position of the humerus and assembled with the anchor.In Mimics,values were assigned based on the CT gray value to obtain a model with normal bone mass(T value ≥-1.0).The parameters were changed to construct models with reduced bone mass(-2.5＜T value＜-1.0)and osteoporosis(T value＜-2.5).In each model,a 70 N pulling force was applied to the anchor along the direction tangent to the inner edge of the bone tunnel.The stress distribution and magnitude of the bone tunnel and the anchor when inserted at different depths under different bone density conditions were observed.RESULTS AND CONCLUSION:(1)When the insertion depth was the same,as the bone density decreased,the maximum equivalent stress of the anchor increased,while the maximum equivalent stress of the bone tunnel decreased.(2)When the bone density was the same,as the insertion depth of the anchor increased,the maximum equivalent stress of the anchor decreased.When the insertion depth was 4 mm,the stress of the bone tunnel was the smallest and the distribution was relatively uniform.The stress of the anchor was mainly distributed around the lower anchor hole and the proximal thread,and the stress of the bone tunnel was mainly at the part in contact with the proximal thread.The increase in the insertion depth would change the uniformity and pattern of the stress distribution,while the bone density had a relatively small impact on the stress distribution pattern.(3)It is concluded that the bone density of the humerus is crucial for the anchor repair of rotator cuff tears.It is recommended that clinicians measure the bone density of the greater tuberosity of the humerus before the operation.Excessive insertion depth of the anchor does not significantly increase its stability.Clinicians can conduct personalized preoperative assessments by using the finite element analysis method in combination with the actual situation of patients to achieve the best surgical results.

ObjectiveTo investigate the effect of Sanet Vision Integrator (SVI)-based visuomotor integration training on the severity of neglect symptoms, upper limb motor function and activities of daily living (ADL) in patients with post-stroke unilateral spatial neglect (USN). MethodsFrom July, 2023 to September, 2025, 41 patients with post-stroke USN in Beijing Bo'ai Hospital were enrolled and randomly assigned to control group (n = 20) and experimental group (n = 21). Both groups received conventional rehabilitation and visual scanning training, while the experimental group received supplementary SVI-based visuomotor integration training, including saccadic, rotation and hand-eye coordination training, for eight weeks. They were assessed with Chinese Behavioral Inattention Test-Hong Kong version (CBIT-HK), Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and modified Barthel Index (MBI) before and after treatment. ResultsAfter treatment, all the scores significantly improved in both groups (|t| > 4.004, P < 0.001), and the total scores of CBIT-HK and the core visual search sub-items (star cancellation, line crossing and letter cancellation), FMA-UE and MBI were better in the experimental group than in the control group (t > 2.096, P < 0.05). ConclusionSVI-based visuomotor training can effectively alleviate the USN symptoms, broaden the span of visual attention, facilitate the functional recovery of the affected upper extremity, and improve ADL in patients after stroke.

BACKGROUND:Osteoblasts are the main cell types responsible for bone formation and remodeling,and the normal performance of their function is precisely regulated by various signaling pathways.Among them,the bone morphogenetic protein and Wnt signaling pathways play a key role in osteogenesis. OBJECTIVE:To review the role of bone morphogenetic protein/Wnt signaling pathway in the regulation of osteoblast function and analyze its changes in different physiological and pathological conditions in order to further reveal the molecular mechanism of bone formation and remodeling. METHODS:The Chinese and English search terms"BMP signaling pathway,Wnt signaling pathway,and osteogenesis"were searched in CNKI,Wanfang,and PubMed databases for original researches published from the inception to June 2023.Totally 61 articles were finally selected for analysis and summary.Using the method of the literature review,the studies of the bone morphogenetic protein/Wnt signaling pathway in regulating osteogenesis were sorted out and analyzed. RESULTS AND CONCLUSION:(1)Bone morphogenetic protein and Wnt signaling pathways play important roles in the differentiation,proliferation,and maturation of osteoblasts.Bone morphogenetic protein signaling pathway mainly regulates the expression of osteogenesis-related genes through the activation of Smad protein.Smad protein enters the nucleus and regulates the expression of genes related to osteogenesis.Different Wnt signaling pathway from bone morphogenetic protein mainly depends on the activation of β-catenin to exert its biological effects.(2)The regulatory effect of bone morphogenetic protein/Wnt signaling pathway will be affected by many factors in different physiological and pathological states.Growth factors,hormones,and mechanical stress can affect the activity of bone morphogenetic protein/Wnt signaling pathway to some extent.(3)Bone morphogenetic protein/Wnt signaling pathway interacts with other signaling pathways in the regulation of osteogenesis,and they together constitute a complex regulatory network.(4)Chinese medicine and natural compounds can promote bone health by regulating signaling pathways,providing new possibilities for treating bone diseases.(5)Future studies can further explore the interaction of bone morphogenetic protein/Wnt signaling pathway and other signaling pathways and its changes in different physiological and pathological conditions,resolve the key nodes and regulation mechanism in the complex network,to provide more precise targets for the treatment of bone-related diseases,and also provide new ideas to reveal the molecular mechanism of bone formation and remodeling.

Objective:To investigate the effects of remote ischemic preconditioning (RIPC) on myocardial injury after non-cardiac surgery (MINS) in elderly patients with hip fracture.Methods:A prospective randomized controlled trial was conducted on 78 elderly patients with hip fracture admitted to the Seventh Medical Center of the PLA General Hospital between October 2023 and September 2024. The patients were divided into RIPC group and non-RIPC group using a random number table. They were treated with closed reduction internal fixation, open reduction internal fixation, or hip arthroplasty for hip fracture under regional anesthesia. The RIPC group received RIPC intervention on the day before surgery and after entering the operating room on the day of surgery (3 cycles of 5-minute upper limb exsanguination followed by 5-minute reperfusion using an inflatable tourniquet cuff). The non-RIPC group received the same perioperative management as the RIPC group except RIPC. Plasma high-sensitivity cardiac troponin I (hs-cTnI) concentrations were measured at admission, immediately after surgery, on the morning of the first postoperative day, and on the morning of the third postoperative day and MINS incidence was calculated based on the hs-cTnI concentrations. The incidence of MINS within 3 days postoperatively and the intraoperative complications were compared in the overall cohort and in age-stratified groups (<80 years, ≥80 years). The local adverse reactions at the RIPC application sites were observed within 3 days after surgery.Results:Among the 78 elderly patients with hip fracture, including 21 males and 57 females, aged 60-99 years [79.5(70.0, 87.0)years], 40 were assigned to the RIPC group and 38 to the non-RIPC group. No significant difference was found in the general data of the two groups. There was no significant difference in the overall MINS incidence between the two groups ( P>0.05). In the patients aged <80 years, no MINS incidence was found (0/21) in the RIPC group, compared with 22% (4/18) in the non-RIPC group ( P<0.05), while in the patients aged ≥80 years, no significant difference in MINS incidence was observed between the two groups ( P>0.05). There were no significant differences in intraoperative complication rates in the overall cohort, patients aged <80 years, or patients aged ≥80 years ( P>0.05). None of the patients had local adverse reactions at the RIPC application sites. Conclusion:For elderly patients with hip fracture who received regional anesthesia, RIPC can significantly reduce the incidence of MINS in patients aged <80 years, but exerts no significant effect on MINS incidence in the overall cohort or in patients aged ≥80 years.

Objective:To investigate children's attention deficit hyperactivity disorder symptoms and their im-pact on parental anxiety and depression,as well as the mediating role of parent-child relationship.Methods:A total of 472 children with ADHD who met the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Dis-orders,Fourth Edition(DSM-Ⅳ)were selected.The severity of ADHD symptoms was assessed using the Attention Deficit Hyperactivity Disorder Rating Scale(ADHD-RS),parent-child relationships were assessed using the Parent-Child Relationship Test(PCRT),and parental anxiety and depression were assessed using the Generalized Anxiety Disorder 7-item Scale(GAD-7)and the Patient Health Questionnaire-9(PHQ-9),respectively.Mediation analysis was conducted following structural equation modeling construction.Results:There was a positive correlation be-tween ADHD-RS scores and PCRT scores,parental GAD-7 scores,and PHQ-9 scores(r=0.19-0.29,Ps＜0.001).PCRT scores significantly mediated the relationship between ADHD-RS total scores and parental GAD-7 and PHQ-9 scores(β=0.02-0.03,Ps＜0.05).PCRT scores did not significantly mediate the relationship between ADHD-RS inattention scores and parental GAD-7 and PHQ-9 scores(β=0.01-0.02,Ps＞0.05).PCRT scores significantly mediated the relationship between ADHD-RS hyperactivity/impulsivity scores and parental GAD-7 and PHQ-9 scores(β=0.02,Ps＜0.05).Conclusion:The symptoms of ADHD in children are associated with parental anxiety and depression symptoms,with parent-child relationships mediating this relationship.

Objective:To explore the clinicopathological features and prognosis of double primary cancer of breast cancer and lung cancer.Methods:A total of 40 patients with breast cancer and lung cancer admitted to Beijing Friendship Hospital, Capital Medical University from December 2015 to December 2023 were retrospectively selected, and the clinicopathological characteristics and prognosis of patients with double primary cancer included in the study were analyzed. The count data were expressed as the number of cases and percentage, Chi-test was used for inter-group comparison or Fisher exact probability method was used for single frequency < 5, rank sum test was used for inter-group comparison of two-sample levels, and Kruskal-Walllis H test was used for inter-group comparison of three-sample levels. The survival rate and survival were analyzed by Kaplan-Meier method, and the survival curve was compared by Log-rank method. Results:Among the 40 patients, 50% were patients with simultaneous and metachronous double primary cancer. And there were statistically significant differences between the two groups in the number of lymph node metastases and whether to receive endocrine therapy ( P=0.025, 0.028). There were 32 patients firstly appear breast cancer, while 8 patients firstly appear lung cancer. And there were statistically significant differences in the body mass index and TNM stage of breast cancer between the two groups ( P=0.004, 0.015). The proportion of progesterone receptor positive patients with human epidermal growth factor receptor 2 low-expression in breast cancer was significantly higher than that in patients with HER2 non-expression and HER2 overexpression ( P=0.023). 92.5% of patients had lung adenocarcinoma, and 77.5% of patients were clinical stage I of lung cancer, and the overall survival of patients who received adjuvant therapy after lung cancer surgery was significantly lower than that of patients without adjuvant therapy, the difference was statistically significant ( P<0.001). Conclusion:The prognosis of patients receiving adjuvant therapy after lung cancer surgery is poor, and regular follow-up after breast cancer surgery is helpful for early detection and early treatment of lung cancer.

The activation proteins released by fibroblasts in the tumor microenvironment regulate tumor growth, migration, and treatment response, thereby influencing tumor progression and therapeutic outcomes. Owing to the proliferation and metastasis of tumors, fibroblast activation protein (FAP) is typically highly expressed in the tumor stroma, whereas it is nearly absent in adult normal tissues and benign lesions, making it an attractive target for precision medicine. Radiolabeled agents targeting FAP have the potential for targeted cancer diagnosis and therapy. This comprehensive review aims to describe the evolution of FAPI-based radiopharmaceuticals and their structural optimization. Within its scope, this review summarizes the advances in the use of radiolabeled small molecule inhibitors for tumor imaging and therapy as well as the modification strategies for FAPIs, combined with insights from structure-activity relationships and clinical studies, providing a valuable perspective for radiopharmaceutical clinical development and application.
