Osteoporosis is a common senile bone metabolism disease, clinically characterized by decreased bone mass, destruction of bone microstructure, increased bone fragility, and easy fracture. It tends to occur in the elderly and postmenopausal women, seriously threatening the quality of life and physical and mental health of the elderly. At present, the treatment of osteoporosis is mainly based on oral western medicines, such as calcium, Vitamin D, and bisphosphonates. Still, there are drawbacks such as a long medication cycle and many adverse reactions. In recent years, due to the advantages of multi-component, multi-pathway, and multi-target, some traditional Chinese medicines and effective ingredients can regulate the osteogenic and osteoclastic differentiation process in both directions and are widely used in the prevention and treatment of osteoporosis. Hippophae rhamnoides is a commonly used herbal medicine, and its fruits are rich in flavonoids, polyphenols, fatty acids, vitamins, and trace elements, which have been proven to have a good anti-osteoporosis effect. Isorhamnetin is the main effective ingredient of Hippophae rhamnoides fruits, which has many pharmacological effects such as anti-inflammation, anti-oxidative stress, anti-aging, and anti-tumor. Studies have shown that isorhamnetin can participate in the regulation of bone metabolism and has a good anti-osteoporosis effect. However, the pharmacological effects and related mechanisms of isorhamnetin against osteoporosis have not been systematically summarized. Therefore, this paper reviewed the pharmacological effects and related mechanisms of isorhamnetin against osteoporosis by referring to relevant literature to provide more basis for the development and application of isorhamnetin.

To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen, kidney essence deficiency, liver constraint transforming into fire, and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen (TE 21), Tinggong (SI 19), Tinghui (GB 2), Shenmai (BL 62) to regulate qi and blood, and supporting with Baihui (GV 20), Yintang (EX-HN 3), Taichong (LR 3), and Yanglingquan (GB 34) to soothe the liver, resolve constraint, and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction (益气聪明汤) and Tongqi Powder (通气散), and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder (温清散) to navel moxibustion.

OBJECTIVE To provide reference for rational clinical use of immune checkpoint inhibitor (ICI). METHODS Electronic medical record information of patients who received ICI treatment from January 1st 2020 to December 31st 2023 at a certain hospital was collected. Patients were divided into thyroid immune-related adverse event (irAE) group (subdivided into clinical hypothyroidism, clinical hyperthyroidism, subclinical hypothyroidism, and subclinical hyperthyroidism subgroups) and non- thyroid irAE group based on whether they experienced immune-induced thyroid irAE. Univariate and multivariate Logistic regression analyses were employed to analyze the influencing factors of ICI-related thyroid adverse events. RESULTS A total of 382 patients who received ICI treatment were included, with 137 cases in the thyroid irAE group (accounting for 35.9%) and 245 cases in the non-thyroid irAE group (accounting for 64.1%). Multivariate Logistic regression analysis, following univariate screening, revealed that ICI combined with radiotherapy was positively associated with the occurrence of thyroid irAE [odds ratio (OR)=2.157, 95% confidence interval (CI) (1.144, 4.066), P<0.05], while lung squamous cell carcinoma was negatively associated with the occurrence of thyroid irAE [OR=0.600, 95%CI (0.369, 0.975), P<0.05]. Among various thyroid irAE, nasopharyngeal malignancy was positively associated with the occurrence of immune-related clinical hyperthyroidism [OR=4.678, 95%CI (1.149, 19.042), P<0.05]; ICI combined with radiotherapy [OR=2.622, 95%CI (1.227, 5.603), P<0.05] and lung adenocarcinoma [OR=2.013, 95%CI (1.078, 3.759), P<0.05] were positively associated with the occurrence of immune-related subclinical hyperthyroidism. Age was negatively associated with the occurrence of immune-related clinical hypothyroidism [OR=0.944, 95%CI (0.896, 0.995), P<0.05]; age [OR=0.963, 95%CI (0.932, 0.994), P<0.05] and ICI combined with chemotherapy [OR=0.332, 95%CI (0.137, 0.802), P<0.05] were negatively associated with the occurrence of immune-related subclinical hypothyroidism. CONCLUSIONS Among patients receiving ICI treatment, younger patients are more prone to thyroid irAE. Patients receiving ICI combined with chemotherapy are less likely to experience subclinical hypothyroidism, while ICI combined with radiotherapy significantly increases the risk of thyroid adverse events.

Objective:
To explore the impacts of coal mine dust on lung function in rats, so as to provide the basis for the early prevention and treatment of coal worker's pneumoconiosis.
Methods:
Seventy-two SPF-grade 8-week-old male Sprague-Dawley rats were randomly divided into the coal dust group, the coal-silica dust group, the silica dust group and the control group. The rats in the first three groups of rats were administered 1 mL corresponding dust suspension into the lungs using non-exposure tracheal instillation, while the rats in the control group were administered 1 mL normal saline. Respiratory rate (f), forced vital capacity (FVC), peak expiratory flow (PEF) and dynamic pulmonary compliance (Cdyn) were measured at 1, 3 and 6 months after dust exposure. Lung tissues were collected to measure reactive oxygen species (ROS) and adenosine triphosphate (ATP) levels using corresponding ELISA kits and ATP assay kits, respectively. The relative mRNA expressions of peroxisome proliferators-activated receptor gamma coactivator 1-alpha (PGC-1α) and mitochondrial transcription factor A (TFAM) were detected using real-time fluorescent quantitative polymerase chain reaction assay. The relative protein expressions of PGC-1α and TFAM were detected using Western blotting.
Results:
There was no interaction between dust type and exposure duration on f (P>0.05), but there were interactions on FVC, PEF and Cdyn (all P<0.05). Compared with the control group at 6 months after dust exposure, the f of the rats in the silica dust group were increased, while the FVC and PEF of the rats in the coal-silica dust and silica dust groups were decreased, and Cdyn of the rats in the coal dust, coal-silica dust and silica dust groups were decreased (all P<0.05). There were interactions between dust type and exposure duration on ROS and ATP levels, the relative mRNA and protein expressions of PGC-1α and TFAM (all P<0.05). Compared with the control group at 3 and 6 months after dust exposure, the ROS levels in the rats in the coal dust, coal-silica dust and silica dust groups were increased, while the ATP levels, the relative mRNA and protein expressions of PGC-1α and TFAM were decreased (all P<0.05).
Conclusion
The lung function impairment in rats caused by different types of coal mine dust is related to PGC-1α-mediated mitochondrial biogenesis dysfunction, which leads to increased ROS levels, decreased ATP and TFAM levels.

With the rapid development of artificial intelligence (AI) technology, the ethical governance of AI has gained increasing attention. The Recommendation on the Ethics of Artificial Intelligence was issued by the United Nations Educational, Scientific and Cultural Organization in 2021, which clarified several principles for the ethical governance of AI. In the field of rehabilitation medicine, the research and application of AI technology have significantly improved patients’ quality of life and survival. However, due to the specificity of the service population in rehabilitation medicine, which is mostly for the sick, injured, disabled, and elderly, a series of complex ethical issues have also arisen. This paper analyzed in detail the ethical issues and challenges encountered in the research and application of AI technology in the field of rehabilitation medicine from various aspects, such as informed consent, security of privacy and data, patients’ physical and mental rehabilitation, compliance regulation, protection of specific groups, and promotion of equity. According to the principles of the Recommendation on the Ethics of Artificial Intelligence and others, response strategies were proposed, including multi-party collaboration and interdisciplinary cooperation, improving and refining relevant laws and regulations, strengthening ethical education across society, establishing accountability mechanisms, increasing investment, promoting equity, and other measures, to promote the healthy development of research and application of AI technology in the field of rehabilitation, as well as benefit humanity.

Alzheimer’s disease (AD) is a prevalent neurodegenerative condition characterized by progressive cognitive decline and memory loss. As the incidence of AD continues to rise annually, researchers have shown keen interest in the active components found in natural plants and their neuroprotective effects against AD. Quercetin, a flavonol widely present in fruits and vegetables, has multiple biological effects including anticancer, anti-inflammatory, and antioxidant. Oxidative stress plays a central role in the pathogenesis of AD, and the antioxidant properties of quercetin are essential for its neuroprotective function. Quercetin can modulate multiple signaling pathways related to AD, such as Nrf2-ARE, JNK, p38 MAPK, PON2, PI3K/Akt, and PKC, all of which are closely related to oxidative stress. Furthermore, quercetin is capable of inhibiting the aggregation of β‑amyloid protein (Aβ) and the phosphorylation of tau protein, as well as the activity of β‑secretase 1 and acetylcholinesterase, thus slowing down the progression of the disease.The review also provides insights into the pharmacokinetic properties of quercetin, including its absorption, metabolism, and excretion, as well as its bioavailability challenges and clinical applications. To improve the bioavailability and enhance the targeting of quercetin, the potential of quercetin nanomedicine delivery systems in the treatment of AD is also discussed. In summary, the multifaceted mechanisms of quercetin against AD provide a new perspective for drug development. However, translating these findings into clinical practice requires overcoming current limitations and ongoing research. In this way, its therapeutic potential in the treatment of AD can be fully utilized.

Objective:
To examine the application of multi-disciplinary treatment (MDT) in the diagnosis and management of recurrence and metastasis of adenoid cystic carcinoma (ACC) of the palate, as well as the treatment of concurrent massive palatal bleeding. This article aimed to provide references for the diagnosis and treatment of patients with advanced oral cancer, along with strategies for managing massive hemorrhage.
Methods:
This article reported on the MDT process for a patient diagnosed with ACC of the left upper palate, who experienced skull base recurrence and lung metastasis following surgery and radiotherapy. The case was further complicated by massive palatal hemorrhage. Additionally, the article analyzed patients with ACC recurrence and significant hemorrhage in the context of relevant literature. The patient was a 36-year-old female with ACC located in the left palate, initially diagnosed at clinical stage T3N0M0 in 2013. She underwent an extensive resection of the palatal lesion, followed by radioactive 125I seed implantation, which was guided by a radiotherapy planning system (TPS) and a digital guide. The patient was monitored for four years post-surgery, during which no signs of tumor recurrence were observed. However, at the fifth year of follow-up, the patient developed recurrence with lung metastasis, classified as T4N0M1. Following a multidisciplinary consultation involving the oral and maxillofacial surgery, radiotherapy, medical oncology, and thoracic surgery, the patient underwent a procedure comprising left subtotal maxillary resection, autologous free flap transplantation, and thoracoscopic resection of pulmonary metastases. After surgery, the patient received 60 Gy of radiotherapy and was orally administered Anlotinib hydrochloride capsules to suppress tumor growth. After 31 months of follow-up, the patient reported experiencing slight bleeding in the mouth. A craniomaxillofacial CT scan revealed that the tumor had grown aggressively, resulting in destruction of the skull base. Consequently, the patient was admitted to the hospital. On the second day of admission, she experienced a sudden episode of oral bleeding. Despite the application of pressure, the bleeding continued unabated. An emergency tracheotomy was performed to relieve the obstruction of the patient’s respiratory tract, and a red blood cell suspension was transfused to address the hemorrhagic shock. Following an urgent consultation with the vascular interventional surgery department, super-selective embolization was promptly employed to effectively halt the bleeding and achieve rapid vascular occlusion. An individualized treatment plan was developed under MDT, incorporating postoperative radiotherapy, targeted therapies, and immunotherapy to manage the tumor.
Results:
Through the MDT model, the patient successfully achieved emergency hemostasis, and normal vital signs were restored. With the addition of radiotherapy and immune-targeted drug treatment, tumor progression was effectively controlled, leading to an improved quality of life for the patient, who successfully survived for 129 months with the tumor by July 2024. A review of the relevant literature indicated that MDT offered significant advantages in the management of adenoid cystic carcinoma. In selecting surgical methods, the team administering MDT could comprehensively evaluate factors such as the patient’s age, physical condition, tumor location, size, and extent of invasion to develop a personalized treatment plan. Radical surgical resection was a common treatment option for ACC. Postoperative tissue defects could be restored to their corresponding functions and aesthetic appearance through autologous tissue reconstruction, utilizing techniques such as peroneal myocutaneous flaps or iliac myocutaneous flaps, or by the implantation of artificial materials. In complex cases involving positive margins, recurrence, and metastasis, the MDT model employed interdisciplinary collaboration to devise a comprehensive treatment plan that may have included re-operation, radiotherapy, and chemotherapy, with the aim of minimizing the risk of ACC recurrence and controlling distant metastasis. Massive bleeding resulting from advanced oral cancer presented a complex medical challenge, influenced by various risk factors such as tumor type, metastasis, treatment options, and the patient’s overall condition. Early identification of bleeding risks, along with strategies to mitigate the adverse effects of bleeding on disease progression—through supportive care, medical treatment, surgical intervention, and interventional therapy—could significantly enhance patients’ quality of life.
Conclusion
The MDT model can provide comprehensive, precise, and personalized treatment plans for patients with advanced oral cancer and massive hemorrhage and improve the effectiveness of treatment strategies.

BackgroundIn recent years, the incidence of non-suicidal self-injury (NSSI) behaviors among adolescents has been increasing annually. Self-esteem and alexithymia are strongly associated with NSSI behaviors, and alienation is closely linked to both self-esteem and alexithymia. However, there is limited research on the relationship between alienation and NSSI behaviors among adolescents in China. ObjectiveTo analyze the relationship between alienation and NSSI behaviors among adolescents, and to explore the factors influencing NSSI behaviors in this population, so as to provide insights for the prevention and treatment of NSSI behaviors in adolescents. MethodsAdolescents admitted to the Department of Psychiatry and Psychology at the 923rd Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from September 1, 2021 to March 1, 2023, who met the diagnostic criteria for NSSI in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), were selected as the study group (n=60). Concurrently, middle school students from Nanning were recruited as the control group (n=60). Participants were assessed using Adolescent Self Harm Scale (ASHS), Rosenberg Self-Esteem Scale (RSES), Toronto Alexithymia Scale (TAS) and Adolescent Students′ Alienation Scale (ASAS). Pearson correlation analysis was employed to examine the relationships between scale scores in the study group, and Logistic regression analysis was used to identify the influencing factors of NSSI behaviors among adolescents. ResultsThe RSES score of the study group was significantly lower than that of the control group (t=-7.033, P<0.01). The TAS and ASAS scores of the study group were significantly higher than those of the control group (t=5.591, 8.124, P<0.01). The ASHS score was negatively correlated with RSES score (r=-0.410, P<0.01) and positively correlated with ASAS score (r=0.555, P<0.01). The RSES scores of the study group were negatively correlated with TAS and ASAS scores (r=-0.317, -0.590, P<0.05 or 0.01). Logistic regression analysis showed that being female (OR=0.714, 95% CI: 0.042~0.709) was a protective factor for NSSI behaviors among adolescents, while high alienation (OR=1.028, 95% CI: 1.013~1.043) and residing in rural areas (OR=6.692, 95% CI: 2.038~21.967) were risk factors for NSSI behaviors among adolescents. ConclusionAlienation was positively correlated with NSSI behaviors in adolescents. Female adolescents had a lower risk of NSSI behaviors, while those with higher levels of alienation or residing in rural areas were more prone to NSSI behaviors.

Objective :
To observe the brain tissue injury during hypoxia-ischemia, as well as the pathological changes and the expression of ferroptosis-related factors after the use of Shenfu injection(SFI), and to explore the protective effect of SFI on hypoxic-ischemic brain injury(HIBD) by inhibiting ferroptosis.
Methods :
An animal model of HIBD in SD rats was constructed and intervened with SFI. Pathologic changes in brain tissue were observed by HE staining methods. Nissen staining was used to observe neuron survival. Glutathione Peroxidase 4(GPX4) and Divalent Metal Transporter 1(DMT1) expression were detected in brain tissue by Western blot, immunohistochemistry and immunofluorescence. Reduced Glutathione(GSH), Lactate Dehydrogenase(LDH), Malondialdehyde(MDA), Superoxide Dismutase(SOD) and tissue iron content were determined with the kits. BV-2 microglial cell line(BV2) cells were culturedin vitroand divided into control group(Ctrl group), oxygen-glucose deprivation group(OGD group), iron ferroptosis-inducing group(Erastin group), iron ferroptosis-inhibiting group(Fer-1 group), Shenfu injection group(SFI group), and Erastin+Shenfu injection group(Erastin+SFI group). 2′,7′-Dichlorodihydrofluorescein diacetate(DCFH-DA) reactive oxygen species(ROS) fluorescent probe was used to detect the ROS release level; Immunofluorescence was used to observe intracellular GPX4, DMT1 expression.
Results :
Compared with the Sham group, rats in the HIBD group showed significant neuronal cell damage in brain tissue, decreased GPX4 expression(P<0.01), increased DMT1 expression(P<0.01), decreased GSH and SOD levels(P<0.01), and increased LDH, MDA and tissue iron levels(P<0.05,P<0.05,P<0.01). In contrast, after the intervention of SFI, GPX4 expression was elevated(P<0.01), DMT1 expression decreased(P<0.01), GSH and SOD levels were elevated(P<0.01), and LDH, MDA, and tissue iron levels decreased(P<0.05,P<0.05,P<0.01). The cells experiments showed that compared with the Ctrl group, the OGD group had a significantly higher ROS content and a decrease in the expression of GPX4 fluorescence intensity, and an increase in the fluorescence intensity of DMT1(P<0.01), compared with the OGD group, the ROS content was reduced in the SFI group, while the expression of GPX4 was elevated and the expression of DMT1 was reduced(P<0.01).
Conclusion
Hippocampal and cortical regions are severely damaged after HIBD in neonatal rats, and their brain tissues show decreased expression of GPX4 and increased expression of DMT1. The above suggests that ferroptosis is involved in HIBD brain injury in neonatal rats. In contrast, Shenfu injection has a protective effect on HIBD experimental animal model and BV2 cell injury model by reducing iron aggregation and ROS production.
