Osteoporosis is a common bone disease， whose incidence is still on the rise， posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress， inflammatory response， and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation， oxidative stress， etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB （NF-κB） ligand （RANKL） pathway， osteoprotegerin （OPG） pathway， Wnt/β-catenin pathway， NF-κB pathway， mitogen-activated protein kinase （MAPK） pathway， adenosine monophosphate （AMP）-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway， and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine， aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

BACKGROUND: China is seeing a growing demand for rehabilitation treatments for post-stroke upper limb spastic paresis (PSSP-UL). Although acupuncture is known to be effective for PSSP-UL, there is room to enhance its efficacy. OBJECTIVE: This study explored a semi-personalized acupuncture approach for PSSP-UL that used three-dimensional kinematic analysis (3DKA) results to select additional acupoints, and investigated the feasibility, efficacy and safety of this approach. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This single-blind, single-center, randomized, controlled trial involved 74 participants who experienced a first-ever ischemic or hemorrhagic stroke with spastic upper limb paresis. The participants were then randomly assigned to the intervention group or the control group in a 1:1 ratio. Both groups received conventional treatments and acupuncture treatment 5 days a week for 4 weeks. The main acupoints in both groups were the same, while participants in the intervention group received additional acupoints selected on the basis of 3DKA results. Follow-up assessments were conducted for 8 weeks after the treatment. MAIN OUTCOME MEASURES: The primary outcome was the Fugl-Meyer Assessment for Upper Extremity (FMA-UE) response rate (≥ 6-point change) at week 4. Secondary outcomes included changes in motor function (FMA-UE), Brunnstrom recovery stage (BRS), manual muscle test (MMT), spasticity (Modified Ashworth Scale, MAS), and activities of daily life (Modified Barthel Index, MBI) at week 4 and week 12. RESULTS: Sixty-four participants completed the trial and underwent analyses. Compared with control group, the intervention group exhibited a significantly higher FMA-UE response rate at week 4 (χ² = 5.479, P = 0.019) and greater improvements in FMA-UE at both week 4 and week 12 (both P < 0.001). The intervention group also showed bigger improvements from baseline in the MMT grades for shoulder adduction and elbow flexion at weeks 4 and 12 as well as thumb adduction at week 4 (P = 0.007, P = 0.049, P = 0.019, P = 0.008, P = 0.029, respectively). The intervention group showed a better change in the MBI at both week 4 and week 12 (P = 0.004 and P = 0.010, respectively). Although the intervention group had a higher BRS for the hand at week 12 (P = 0.041), no intergroup differences were observed at week 4 (all P > 0.05). The two groups showed no differences in MAS grades as well as in BRS for the arm at weeks 4 and 12 (all P > 0.05). CONCLUSION: Semi-personalized acupuncture prescription based on 3DKA results significantly improved motor function, muscle strength, and activities of daily living in patients with PSSP-UL.

Malignant pleural effusion(MPE)is a common complication in patients with advanced malignant tumors,which not only significantly reduces their quality of life but also shortens their survival duration.Despite the widespread use of traditional treatment methods such as thoracentesis and pleurodesis,their efficacy is limited accompanied by high recurrence rates.Therefore,exploring novel therapeutic strategies becomes particularly urgent.In recent years,immunotherapy has attracted extensive attention for its potential in cancer treatment.This article systematically reviews the roles of CD4+T cell subsets,including regulatory T cells(Treg),T helper cell(Th)17,Th9,and Th22 cells,within the immunosuppressive microenvironment of MPE.These cell subsets are involved in the formation of the immunosuppressive state of MPE through various mechanisms and play key roles in the occurrence and development of the disease.In addition,the article discusses in detail the role of immune checkpoint molecules,such as programmed death protein 1(PD-1),PD-1 ligand(PD-L1),and cytotoxic T-lymphocyte-associated protein 4(CTLA-4),in the immune evasion of MPE.The abnormal expressions of these molecules provide opportunity for tumor cells to evade immune system surveillance.At the same time,this article also summarizes the application prospects of novel immunotherapy strategies,such as adoptive cell therapy(ACT)and chimeric antigen receptor T cell(CAR-T)therapy,in the treatment of MPE.These innovative therapies offer possibilities for improving the prognosis of MPE patients through activating and enhancing the anti-tumor immune response.

OBJECTIVE To investigate the relationship between clinical features and human papillomavirus(HPV)infection and the expression of hypoxia-inducible factor(HIF)and vascular endothelial growth factor(VEGF)in patients with pharyngeal and laryngeal papilloma.METHODS Adult patients with pharyngeal and laryngeal papilloma admitted to Beijing Tongren Hospital Affiliated to Capital Medical University from October 2022 to February 2024 were selected as the test group,and adult patients with non-inflammatory non-tumor throat lesions were selected as the control group.Clinical data and pathological tissue samples were collected.The differences of pharyngeal and laryngeal papilloma patients in symptoms,age,gender,smoking,drinking,the number of lesion involved sites and the number of operations were compared.Real-time fluorescence quantitative PCR was used to detect the expression of HPV DNA,HIF cDNA and VEGF cDNA in the pathological tissues.RESULTS The symptoms of pharyngeal papilloma are less severe than those of laryngeal papilloma.There were no statistically significant differences between the two groups in terms of gender and alcohol consumption(P>0.05),but there were statistically significant differences in terms of age,smoking,the number of lesions involved and the number of operations(P<0.05).The number of lesion involved sites was positively correlated with the expression of HIF and VEGF(r=0.3553、r=0.2693,P<0.05).The number of operations was positively correlated with the expression of VEGF(r=0.2515,P<0.05).The expression levels of HIF and VEGF in laryngeal papilloma were higher than those in pharyngeal papilloma and control group(F=9.174,H=23.737,P<0.001).The expression levels of HIF and VEGF in HPV-positive tissue were higher than those in HPV-negative tissue(t=3.899,t=6.463,P<0.001).The HPV positive rate of laryngeal papilloma(97.9%,46/47)was higher than that in pharyngeal papilloma(21.7%,10/46)and control group(13.6%,3/22)(χ2=53.114、χ2=46.647,P<0.001).CONCLUSION HPV infection is one of the important causes of pharyngeal papilloma.The low infection status of pharyngeal papilloma may lead to low expression of HIF and VEGF in the tumor,which makes its clinical features different from laryngeal papilloma.

OBJECTIVE To investigate the improved anesthesia method of arytenoid cartilage reduction under general anesthesia in the treatment of arytenoid dislocation.METHODS The clinical data of 12 patients who underwent modified arytenoid cartilage reduction under general anesthesia in Beijing Tongren Hospital from July 2020 to March 2024 were retrospectively analyzed.To evaluate and analyze the modified anesthesia method of maintaining low degree of neuromuscular block during operation,the recovery of arytenoid cartilage movement and sound after operation.RESULTS All the 12 patients successfully completed arytenoid cartilage reduction.The articulation,arytenoid movement and glottis closure were improved significantly.Compared with the total voice handicap index(VHI),physical scores,functional scores and emotional scores before reduction,the scores at 1 month after surgery were significantly lower[83.5(75-91)vs.13(7-19),30.5(26.5-33)vs.5.5(3-7),25.5(22.5-29)vs.4(2-6),26(23.5-30)vs.4(1.5-6),P<0.001].No complications such as laryngeal spasm and laryngeal edema occurred during perioperative period.CONCLUSION Arytenoid cartilage reduction under modified general anesthesia has high safety,good patient cooperation and high reduction success rate.It provides a new option for the treatment of arytenoid dislocation.

Objective To explore the guiding value of thromboelastography(TEG)in blood transfusion therapy for patients undergoing liver rupture repair.Methods A total of 106 patients who underwent liver rupture repair and were admitted to the hospital from June 2021 to June 2024 were selected.According to the random number table method,the patients were divided into 53 patients who underwent liver rupture repair with TEG detection blood transfusion(study group)and 53 patients who underwent liver rupture repair with conventional coagulation function detection blood transfusion(control group).General information of patients was collected.The levels of coagulation function indicators,the dosage of blood products and intraoperative complications of patients in the study group and the control group before blood transfusion and 24 hours after blood transfusion were compared.Results 24 hours after blood transfusion,the fibrinogen level in the study group was higher than that in the control group,while the prothrombin time,activated partial thromboplastin time and thrombin time were shorter than those in the control group,and the differences were statistically sig-nificant(P<0.05).The dosages of red blood cells,frozen plasma,platelets and cryoprecipitate in the study group were all lower than those in the control group,and the differences were statistically significant(P<0.05).The total incidence of intraoperative complications in the study group was lower than that in the con-trol group,and the difference was statistically significant(P<0.05).Conclusion TEG has significant guiding value in blood transfusion therapy for patients undergoing liver rupture repair.

Approximately 25%of cancers worldwide are related to obesity and sedentary lifestyle.Changing behavior(exer-cise)may be a cost-effective means of prevention and treatment.Studies have found that exercise plays an important role in reducing cancer risk,inhibiting tumor growth,improving cancer-related quality of life,and improving the effectiveness of treatment.However,this protection mechanism is largely unclear.Clarifying the mechanism of action is essential to fully exploit the potential of exercise therapy,this article reviews the possible mechanisms for exercise to reduce the risk of cancer.

Radiotherapy can cause functional and morphological changes in the brain tissues of patients with primary or metastatic malignant brain tumors, leading to radiation-induced brain injury. However, the pathogenesis of radiation-induced brain injury has not yet been unanimously determined, and its research advances and treatment protocols are yet to be elucidated and improved. In this study, we explore the pathogenesis of radiation-induced brain injury from the perspective of vascular injury, inflammatory reactions, neuronal dysfunction, glial cell injury, and gut microbiota and reviewed the advances in research on its treatment and prevention. The purpose is to provide a reference and theoretical basis for the research and clinical diagnosis and treatment of radiation-induced brain injury.

Objective:To investigate the effects of sleep disorders (SD) on the radiation injury of hematopoietic stem cells (HSCs) in bone marrow (BM).Methods:Totolly 56 C57BL/6J male mice aged 6-8 weeks were enrolled in this study. They were subjected to whole body irradiation of 60Co γ-rays with doses of 5.0 and 7.5 Gy. A SD model was established using a SD device. According to the random number table method, the mice were divided into seven groups: the control group (Con group), the SD group, the mere radiation group (IR group), the group of post-irradiation SD (IR+ SD group), the group of post-irradiation SD treated with phosphate buffer solution (IR+ SD+ PBS group), the group of post-irradiation SD treated with GSK2795039 (IR+ SD+ GSK group), and the group of post-irradiation SD treated with N-acetylcysteine (IR+ SD+ NAC group), with in eight mice each group. The changes in the peripheral blood of the mice after 5.0 Gy irradiation were detected using the collected tail venous blood, and the survival rates of the mice after 7.5 Gy irradiation were observed. The changes in the density and count of bone marrow cells were observed using hematoxylin and eosin (HE) staining. The number of hematopoietic stem cells in bone marrow (LSK cells), as well as their apoptosis level and changes in cell cycle, were detected using flow cytometry. Furthermore, indicators of LSK, such as reactive oxygen species(ROS) and mitochondrial-derived reactive oxygen species (mtROS), were analyzed. Nicotinamide adenine dinucleotide phosphate (NADP+ /NADPH) and glutathione (GSSG/GSH) were detected using an enzyme microplate reader in order to observe the oxidative stress level of LSK. Furthermore, flow cytometry was employed to sort the LSK cells from the mice, and flow cytometry was used to detect the expression of NADPH oxidase 2(NOX2) and cysteinyl aspartate specific proteinnase-1(Caspase-1), and polymerase chain reaction (PCR) was used to detect the expression of inflammatory factors such as NOX1-4, interleukin 1β (IL-1β), interleukin 6 (IL-6), interleukin 18 (IL-18), and tumor necrosis factor α (TNF-α). Results:Compared to the IR group, the IR+ SD group exhibited significantly slower recovery of white blood cells (WBC) and platelets (PLT) ( t = 4.39, 6.37, P < 0.05), the bone marrow cell count decreasing from (2.14 ± 0.38) × 10 7 to (3.59 ± 0.29) × 10 7 ( t = 8.55, P < 0.05), significantly decreased proportion of G 0-phase LSK cells, significantly increased proportion of apoptotic cells ( t = 7.53, 8.21, P < 0.05), and significantly increased DCFH-DA, MitoSOX, and NADP+ /NADPH ( t = 22.99, 29.47, 3.77, P<0.05). In the case of IR, SD further promoted the activation of NOX2 and led to increases in the mRNA expression of downstream inflammatory factors such as IL-1β, IL-6, IL-18, and TNF-α ( t = 6.95, 6.01, 8.39, 4.91, 5.56, P < 0.05). Inhibition of NOX2-ROS could prevent the SD-induced aggravation of post-irradiation hematopoietic injury. This significantly reduced the apoptotic rate of LSK cells and the expression of inflammatory factors, ultimately accelerating the hematopoietic recovery of LSK cells ( t = 9.24, 3.92, P < 0.05). Conclusions:SD can aggravate the IR-induced injury of hematopoietic stem cells in bone marrow, primarily by activating the NOX2-ROS-Caspase-1 axis. This will increase the levels of intracellular inflammatory factors and ROS, promote cell apoptosis, and ultimately inhibit the hematopoietic recovery of bone marrow.

Cardiomyopathy is a group of heterogeneous myocardial diseases with a variety of specific phenotypes that can lead to cardiovascular death or progressive heart failure in severe cases.Because of the severity and complexity of these diseases,the search for new regulatory mechanisms to prevent and treat cardiomyopathy is particularly urgent.Iron death is a form of programmed cell death that differs from other forms of iron dependence and is characterized by the accumulation of iron-dependent lipid peroxides.Studies have shown that iron death can be involved in the occurrence and progression of cardiomyopathy through different signaling pathways.Therefore,targeted regulation of iron death is a new strategy to prevent cardiomyopathy.In this paper,the mechanism of iron death and its important role in cardiomyopathy were reviewed to find the potential relationship between iron death and cardiomyopathy and provide more ideas for the treatment of various cardiomyopathies in the future.
