ObjectiveTo elucidate the efficacy connotation of Shudi Qiangjin pills （SQP） against liver and kidney deficiency in steroid-induced osteonecrosis of femoral head （SONFH） from the perspective of the "disease-syndrome-formula" association and to clarify the underlying mechanisms based on in vivo and in vitro experiment validation. MethodsThe chemical components and the corresponding putative targets of SQP were collected from the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP） v2.0， the Encyclopedia of Traditional Chinese Medicine （ETCM） v2.0， and HERB databases. The SONFH-related genes were identified based on the differential expression profiles of peripheral blood of patients with SONFH compared to the healthy volunteers， and the disease phenotype-related targets were collected from the TCMIP v2.0 database. Then， the interaction network of "SONFH-related genes and candidate targets of SQP" was constructed based on "gene-gene interaction information"， and the major network targets were screened by calculating the topological characteristic values of the network followed by the functional mining according to the Kyoto Encyclopedia of Genes and Genomes （KEGG） database and the SoFDA database. After that， the SONFH rat model was prepared by lipopolysaccharide combined with methylprednisolone injection， and 2.5， 5， 7.5 g·kg^-1 SQP （once per day， equivalent to 1， 2， and 3 times the clinical equivalent dose， respectively） or 7.3×10^-3 g·kg^-1 of alendronate sodium （ALS， once per week， equivalent to the clinical equivalent dose） was given for 8 weeks. The effect characteristics of SQP and ALS in the treatment of SONFH were evaluated by micro-computed tomography scanning， hematoxylin and eosin staining， alkaline phosphatase （ALP） staining， immunohistochemical staining， enzyme-linked immunosorbent assay， and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling（TUNEL）staining， and a comparative efficacy analysis was conducted with ALS. In addition， SONFH cell models were prepared by dexamethasone stimulation of osteoblasts， and the intervention was carried out with the medicated serum of SQP at the aforementioned three doses. Cell counting kit-8， ALP staining， ALP activity assay， alizarin red staining， and flow cytometry were employed to investigate the regulatory effect of SQP on osteoblasts. The expression levels of osteogenesis-related proteins and key factors of the target signaling axis were detected by quantitative real-time polymerase chain reaction and Western blot. ResultsThe network analysis results demonstrated that the candidate targets of SQP primarily exerted their therapeutic effects through key signaling pathways， including phosphoinositide 3-kinase（PI3K）/protein kinase B（Akt）， lipid metabolism and atherosclerosis， prolactin， chemokines， and neurotrophic factors pathways. These pathways were significantly involved in critical biological processes such as muscle and bone metabolism and the regulation of the "neuro-endocrine-immune" network， thereby addressing both modern medical symptoms （e.g.， delayed skeletal maturation and recurrent fractures） and traditional Chinese medicine （TCM） symptoms （e.g.， fatigue， aversion to cold， cold limbs， and pain in the limbs and joints in patients with SONFH characterized by liver and kidney deficiency syndrome. Among these pathways， the PI3K/Akt signaling pathway exhibited the highest degree of enrichment. The in vivo experimental results demonstrated that starting from the 4^th week after modeling， the modeling group exhibited a significant reduction in body weight compared to the control group （P<0.05）. After six weeks of treatment， all dosage groups of SQP showed significantly higher body weights compared to the model group （P<0.01）. Compared with the normal group， the model group exhibited significant decreases in bone mineral density （BMD）， bone volume fraction （BV/TV）， trabecular number （Tb.N）， osteocalcin （OCN）， alkaline phosphatase （ALP） levels in femoral head tissue， and serum bone-specific alkaline phosphatase （BALP） （P<0.01）， along with significant increases in trabecular separation （Tb.Sp）， empty lacunae rate in tissue， and apoptosis rate （P<0.01）. In comparison to the model group， the SQP intervention groups showed significant improvements in BMD， BV/TV and Tb.N （P<0.01）， significant reductions in Tb.Sp， empty lacunae rate and apoptosis rate （P<0.05）， and significant increases in protein levels of OCN and ALP as well as BALP content （P<0.05）. The in vitro experimental results revealed that all dosage groups of SQP medicated serum showed no toxic effects on osteoblast. Compared with the normal group， the model group displayed significant suppression of osteoblast proliferation activity， ALP activity， and calcified nodule formation rate （P<0.01）， significant decreases in mRNA transcription levels of OCN and Runt-related transcription factor 2 （RUNX2） （P<0.01）， significant reductions in protein content of osteopontin （OPN）， typeⅠ collagen （ColⅠ）A1， B-cell lymphoma-2 （Bcl-2）， PI3K， and phosphorylated （p）-Akt （P<0.01）， and a significant increase in apoptosis rate （P<0.01）. Compared with the model group， the SQP medicated serum intervention groups exhibited significant increases in proliferation activity， ALP activity， calcified nodule formation rate， mRNA transcription levels of OCN and RUNX2， and protein content of OPN， ColⅠA1， Bcl-2， PI3K， and p-Akt （P<0.05）， along with a significant decrease in apoptosis rate （P<0.01）. ConclusionSQP can effectively reduce the disease severity of SONFH with liver and kidney deficiency syndrome and improve bone microstructure， with the therapeutic effects exhibiting a dose-dependent manner. The mechanism may be related to its regulation of key processes such as muscle and bone metabolism and the correction of imbalances in the "neuro-endocrine-immune" network， thereby promoting osteoblast differentiation and inhibiting osteoblast apoptosis. The PI3K/Akt signaling axis is likely one of the key pathways through which this formula exerts its effects.

Objective: : Acoustic neuromas, or vestibular schwannomas, pose significant surgical challenges due to their proximity to critical cranial nerves, particularly the facial nerve. The primary goal in their surgical treatment is to achieve maximal tumor removal while preserving neurological function. Recent advancements in surgical technology have introduced neuroendoscopy as an adjunctive tool that can enhance visualization during surgery. This study aimed to evaluate the efficacy of integrating neuroendoscopy with intraoperative electrophysiological monitoring in near-total resection surgeries for acoustic neuroma. Methods: : We conducted a retrospective cohort study comparing 71 patients who underwent neuroendoscopy-assisted microsurgery technique with 68 patients who received standard care group technique. Both groups underwent the suboccipital retrosigmoid sinus approach for tumor resection with intraoperative electrophysiological monitoring. Surgical outcomes, including residual tumor size, facial nerve function, audiological outcomes, and complication rates, were compared between the two groups. Results: : The neuroendoscopy-assisted group demonstrated a significantly smaller residual tumor size, improved immediate and 1-year postoperative House-Brackmann grades, and a higher facial nerve preservation rate compared to the standard care group (p<0.05). There was no significant difference in operation time, blood loss, cerebrospinal fluid leakage, or complication rates between the groups. Word recognition scores after a year were significantly higher in the neuroendoscopy-assisted group (p<0.05). Conclusion : The integration of neuroendoscopy-assisted microsurgery technique in acoustic neuroma surgery improves facial nerve function and residual tumor size without increasing surgical complications. These findings support the utility of this combined approach in enhancing surgical outcomes for patients with acoustic neuroma.

ObjectiveTo systematically review the effect of dual-task training (DTT) on mobility and balance in stroke patients. MethodsCNKI, Wanfang Data, VIP, PubMed, Web of Science, Embase and Cochrane Library were searched for randomized controlled trials (RCT) on DTT in stroke rehabilitation from inception to June, 2025. The quality of the included studies was assessed using the Cochrane Risk of Bias Tool and the PEDro scale. Meta-analysis was performed using RevMan 5.4. ResultsA total of eleven RCT involving 517 stroke patients were included, and the scores of PEDro scale were four to eight. DTT was more effective on the score of Fugl-Meyer Assessment-Lower Extremity (MD = 3.70, 95%CI 1.88 to 5.53, P < 0.001) and Berg Balance Scale (BBS) (MD = 3.04, 95%CI 1.58 to 4.49, P < 0.001), fall incidence (OR = 0.32, 95%CI 0.11 to 0.87, P = 0.025), gait speed under a single-task condition (MD = 0.08, 95%CI 0.03 to 0.12, P = 0.002), gait speed under a dual-task condition (MD = 0.13, 95%CI 0.10 to 0.16, P < 0.001), Timed Up and Go Test time (MD = -2.78, 95%CI -3.85 to -1.72, P < 0.001), and score of modified Barthel Index (MD = 4.77, 95%CI 1.88 to 7.66, P = 0.001). Subgroup analysis indicated that motor-motor DTT was more effective than cognitive-motor DTT on BBS scores and single-task gait speed. ConclusionsDTT can improve mobility and balance in stroke patients, especially with motor-motor tasks.

BACKGROUND:Estrogen receptor α can act as an upstream protein to regulate the expression and phosphorylation level of adenosine monophosphate-activated protein kinase(AMPK).Activation of the estrogen receptor α-AMPK signaling pathway promotes osteogenic proliferation and differentiation.OBJECTIVE:To explore the molecular mechanism of estrogen receptor α regulating AMPK and its effect on osteoblast proliferation and differentiation at osteoblast cell line and molecular biology levels.METHODS:(1)The passaged MC3T3-E1 mouse embryonic osteoblasts were divided into three groups:blank control group,mock group(transfected with pCDNA3.1 control plasmid),and estrogen receptor α group(transfected with pCDNA3.1-estrogen receptor α overexpression plasmid),and RT-qPCR and western blot methods were used to detect the hepatic kinase B1,CaMKKβ,and AMPKα1 mRNA,protein and phosphorylation levels.(2)ChIP-qPCR was used to demonstrate that estrogen receptor α interacts with the hepatic kinase B1 promoter.Dual luciferase assay was used to demonstrate that estrogen receptorα interacts with the hepatic kinase B1 promoter region to activate its transcriptional expression.(3)The cells were divided into three groups:mock+shNC group,estrogen receptor α+shNC group,and estrogen receptor α+shLKB1 group.Changes in the expression levels of hepatic kinase B1,phosphorylated hepatic kinase B1,and phosphorylated AMPKα1 proteins in the cells were detected by western blot.(4)The cells were divided into four groups:mock group,estrogen receptor α group,estrogen receptor α+5 μmol/L Compound C(AMPK inhibitor)group,and estrogen receptor α+10 μmol/L Compound C group.The expression of proteins related to the AMPK signaling pathway and related to osteogenesis and osteoinductivity were detected by western blot method.Cells were transfected for 24 hours and then subjected to osteogenic induction for 14 days.Alkaline phosphatase staining was performed and cell viability in each group was detected.Mineralized nodule formation was detected by alizarin red staining at 21 days of osteogenic induction.(5)The cells were transfected and pretreated with different concentrations of AMPK inhibitor in corresponding groups,and cell viability was detected by cell counting kit 8.RESULTS AND CONCLUSION:(1)Estrogen receptor α activates the AMPK signaling pathway in MC3T3-E1 cells.(2)Estrogen receptor α promotes liver kinase B1 transcription and mediates AMPK signaling pathway activation.(3)Estrogen receptor α promotes the proliferation and differentiation of MC3T3-E1 cells by activating the AMPK signaling pathway,and the expression of AMPKα1,p-AMPKα,osteoprotegerin,osteopontin,and Runx2 proteins was down-regulated under the intervention of AMPK inhibitor,and the viability of osteoblasts was decreased.(4)To conclude,estrogen receptor α activates the AMPK signaling pathway by acting on liver kinase B1 promoter,promotes osteoblast proliferation and osteogenic differentiation,and prevents osteoporosis.

OBJECTIVE To investigate the mechanism through which Chaixian Huashen decoction(CXHSD)ameliorates lipopolysaccharide(LPS)-induced acute lung injury(ALI)in mice.METHODS Component analysis:the components of CXHSD extract were analyzed via ultra-high performance liquid chromatography-high resolution mass spectrometry(UPLC-Q-Exactive HFX).Network pharma-cology analysis was conducted to predict the potential active components and underlying therapeutic targets of CXHSD for ALI treatment.① Animal experiment:mice were randomly divided into the normal control group,model(LPS)group,model+dexamethasone(DEX)4 mg·kg-1 group,model+CXHSD 10 g·kg-1 group,and model+CXHSD 20 g·kg-1 group.Except for the normal control group,ALI was induced in all the mice by intratracheal instillation of LPS.Model+CXHSD groups received daily intra-gastric administration of corresponding treatments for 7 consecutive days.The model+DEX group was administered saline intragastrically for the initial 5 d,followed by DEX for the next 2 d.ALI was induced by intratracheal instillation of LPS 5 mg·kg-1 1 h after the 6th administration of CXHSD/DEX.24 h after modeling,the severity of pulmonary edema was assessed using the wet to dry weight(W/D)ratio,and hematoxylin-eosin(HE)staining was used to evaluate histopathological damage.The levels of myeloperoxidase(MPO),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),IL-1β in lung tissue homogenates and serum were measured by enzyme-linked immunosorbent assay(ELISA).The total protein concentration in bronchoalveolar lavage fluid(BALF)was measured by bicinchoninic acid(BCA)assay.Immunohistochemistry and Western blotting were used to assess the expression levels of toll-like receptor 4(TLR4),myeloid differentiation primary response 88(MyD88),zonula occludens-1(ZO-1)and occludin,as well as the phosphorylation level of nuclear factor-kappa B p65(NF-κB p65).② Cell experiment:RAW264.7 cells were divided into the cell control group,LPS 1 mg·L-1 group,LPS 1 mg·L-1+DEX 1 mg·L-1 group,and LPS 1 mg·L-1+CXHSD 50,100 and 200 mg·L-1 groups.After 24 h of culture,the nitric oxide(NO)content was measured with the nitrate reductase method,the levels of TNF-α,IL-1 β and IL-6 in the cell supernatants of each group were detected by ELISA.RESULTS Network pharmacology analysis indicated that CXHSD might alleviate ALI through the NF-κB pathway.① Com-pared with the normal control group,the W/D ratio was elevated,pathological injuries aggravated(such as alveolar wall thickening,inflammatory infiltration,and alveolar congestion),histopathological damage pronounced,MPO activity increased,and total protein concentrations in BALF raised in the model group,in which levels of TNF-α,IL-6 and IL-1 β in both lung tissue and serum became higher.Concur-rently,LPS increased the expressions of p-NF-κB p65,TLR4 and MyD88,but reduced the expressions of ZO-1 and occludin.Compared with the model group,model+CXHSD groups had their pulmonary edema and lung pathological injury ameliorated as evidenced by alleviated alveolar wall thickening,inflammatory infiltration and alveolar congestion.The levels of MPO,TNF-α,IL-1 β and IL-6 in both lung tissue and serum,and the total protein concentrations in BALF were significantly decreased in the model+CXHSD groups.Additionally,the expressions of TLR4,MyD88,and p-NF-κB p65 were significantly downregulated,while those of ZO-1 and occludin were prominently upregulated.② Compared with the cell control,the levels of TNF-α,IL-1 β,IL-6 and NO in the supernatant of RAW264.7 cells were signifi-cantly increased in the LPS group.Compared with the LPS group,in the supernatant of RAW264.7 cells treated with LPS+CXHSD at 100 mg·L-1,there was no significant difference in TNF-α levels.However,in the other groups treated with LPS+CXHSD,the levels of TNF-α,IL-1 β,IL-6,and the content of NO were significantly reduced.CONCLUSION CXHSD can alleviate LPS-induced ALI by inhibiting the TLR4/NF-κB pathway,attenuating inflammation,and preserving pulmonary barrier integrity.
