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.

Objective:To explore the movement patterns and factors influencing lung tumors tracked using the M6 cyberknife stereotactic radiotherapy(SRT)system and to provide a reference for the implementation of precise stereotactic radiotherapy for lung tumors.Method:A retrospective analysis was conducted on 29 patients with lung tumors who were treated using x-sight lung tracking technology and the M6 cyberknife SRT system at Tianjin Medical University Cancer Institute&Hospital,from January 2022 to August 2024.The tumor location and volume,irradiation dose,isodose line,and number of divisions were recorded.Lung tumor location and SPSS 26.0 software were used to analyze the movement amplitude of tumors in the left and right(LFT/RGT,LR)directions,the anterior-posterior(ANT/POS,AP)direction,and the superior-inferior(SUP/INF,SI)direction.The results are expressed as the mean±standard deviation((x)±s)mm,and a t-test was used for inter-group comparisons.Multiple linear regression was used to analyze the effects of factors such as age,gender,tumor location(upper and lower lungs),and tumor volume on the amplitudes of the lung tumor movements.Result:The average motion amplitudes in the LR direc-tions,AP direction,and SI direction of the tumor target areas were(3.5±1.8)mm,(5.3±1.7)mm,and(7.3±5.4)mm for the upper lung,based on 19 cases,and(3.1±1.6)mm,(4.5±2.2)mm,and(12.2±4.4)mm for the lower lung,based on 10 cases,respectively.There was a statistic-ally significant difference(P=0.015 3)in the amplitude of movements between the lower and upper lung tumors in the SI direction.The lung tumor movement amplitude in the SI direction was influenced by tumor location(P=0.035),and the movement amplitudes in the LR direc-tions and the AP direction were not related to factors such as gender,age,tumor location,and tumor volume.Conclusions:The lung tumor movement amplitudes for the different locations varied depending on the respiratory movement shown by the patient.In the SI direction,the movement amplitude of the lower lung tumors was greater than that of upper lung tumors,and this was due to tumor location effects.The movement amplitudes of the lower and upper lung tumors were similar in the LR directions and AP directions.Furthermore,movement amplitude was not affected by gender,age,tumor location,and tumor volume.

Accurate prediction of drug responses in cancer cell lines(CCLs)and transferable prediction of clinical drug responses using CCLs are two major tasks in personalized medicine.Despite the rapid advancements in existing computational methods for preclinical and clinical cancer drug response(CDR)prediction,chal-lenges remain regarding the generalization of new drugs that are unseen in the training set.Herein,we propose a multimodal fusion deep learning(DL)model called drug-target and single-cell language based CDR(DTLCDR)to predict preclinical and clinical CDRs.The model integrates chemical descriptors,mo-lecular graph representations,predicted protein target profiles of drugs,and cell line expression profiles with general knowledge from single cells.Among these features,a well-trained drug-target interaction(DTI)prediction model is used to generate target profiles of drugs,and a pretrained single-cell language model is integrated to provide general genomic knowledge.Comparison experiments on the cell line drug sensitivity dataset demonstrated that DTLCDR exhibited improved generalizability and robustness in predicting unseen drugs compared with previous state-of-the-art baseline methods.Further ablation studies verified the effectiveness of each component of our model,highlighting the significant contribution of target information to generalizability.Subsequently,the ability of DTLCDR to predict novel molecules was validated through in vitro cell experiments,demonstrating its potential for real-world applications.Moreover,DTLCDR was transferred to the clinical datasets,demonstrating satisfactory performance in the clinical data,regardless of whether the drugs were included in the cell line dataset.Overall,our results suggest that the DTLCDR is a promising tool for personalized drug discovery.

Objective:To explore the applied effectiveness of the Skin and/or tissue,Education,Cooperation,Understanding,Report and Evaluate (SECURE) nursing pathway based on action research method in the prevention process of medical device-related pressure injuries (MDRPI) of patients in the Intensive Care Unit (ICU). Methods:The SECURE nursing pathway based on action research method included the establishment of a skin care team to identify problems,and the formulation of conducting intervention plan,and the development of targeting nursing interventions to prevent the occurrence of MDRPI. A total of 84 patients hospitalized in the ICU of Hebei General Hospital from March 2022 to March 2023 were selected,and they were randomly divided into a control group and an observation group,with 42 patients in each group. The control group implemented routine method to prevent MDRPI during ICU treatment,while the observation group implemented SECURE nursing pathway based on action research method to conduct prevention. The MDRPI incidence,the quality scores of ICU nursing,the scores of the Short Form Health Survey-36 (SF-36) of patients,the assessment of the improvement of MDRPI patients,and the satisfaction of patients for nursing care were compared between the two groups. Results:The MDRPI incidence during ICU treatment in the observation group was 4.76％ (2/42),which was significantly lower than that in the control group,with a statistically significant difference (x2=11.052,P<0.05). The average scores for device usage,prevention assessment,positioning management and preventive nursing after nursing intervention in the observation group were respectively (88.45±2.05),(89.36±2.11),(89.25±2.15) and (91.45±2.25),all of which were significantly higher than those in the control group,with statistically significant differences (t=11.425,12.052,10.052,13.478,P<0.05). After nursing intervention,the average scores for physical function,social function,psychological function and material life as the SF-36 scale in the observation group were (85.47±2.05),(86.48±2.05),(88.46±2.15) and (90.25±2.44),respectively,which were respectively higher than those in the control group,with statistically significant differences (t=12.414,11.045,10.252,10.478,P<0.05). The occurrence time,improvement time of wound and ICU treatment time of presenting MDRPI patients in the observation group were respectively (4.05±0.54) days,(3.45±0.15) days,and (8.12±2.14) days. Compared to the control group,the occurrence time of the observation group was longer,while both the improvement time of wound and ICU treatment time of the observation group were shorter,with statistically significant differences (t=8.485,10.012,13.001,P<0.05). The satisfaction degree of nursing care of patients in the observation group was 95.24％ (40/42),which was significantly higher than that in the control group (x2=12.054,P<0.05). Conclusion:The SECURE nursing pathway based on action research method,which prevents MDRPI of ICU patients,can reduce the MDRPI incidence rate of ICU patients,and enhance the work quality of nursing care for MDRPI. It is helpful to the recovery of ICU patients,which can also shorten the treatment time of ICU patients.

Objective To observe the value of C-arm CT stent precision technology in intracranial arterial stent implantation.Methods Data of 38 patients with symptomatic intracranial atherosclerotic stenosis who underwent intracranial arterial stent implantation were retrospectively analyzed.Stent displayed in 2D-digital subtraction angiography(DSA)during and immediately after implantation were observed,and superselective C-arm CT scanning of target artery and stent precision reconstruction were performed.Subjective scoring of display stent structure in 2D-DSA and stent precision reconstruction images were comparatively analyzed,and the clarity rate of displaying stent and detection rate of related complications were compared.Results Totally 45 stents were implanted in 38 patients.In 2D-DSA,the subjective score was 0 of 1,1 of 20 and 2 of 24 stents,respectively.Stent precision reconstruction image showed that subjective score was 0 of 1 stent and was 3 of 44 stents.The clarity rate of displaying stent in stent precision reconstruction image was 97.78％(44/45),much higher than that of 2D-DSA image(0[0/45],P＜0.001).Among 44 stents displayed in 2D-DSA,poor stent opening and abnormal perforator vessel was observed in each 1 stent,and no clear abnormality was found in the rest stents.Among 44 stents revealed in stent precision reconstruction images,poor stent opening,thromboses in stent and stent mesh protruding into vascular lumen were found each in 2 stents,while perforator vessel spasm and localized stenosis after stent implantation were noticed in 3 stents.Arterial dissection occurred in 8 stents during balloon dilation,after timely implantation of a new stent,stent precision reconstruction images showed the dissection rupture was completely covered.The complications of stent precision reconstruction was higher than that of 2D-DSA(38.64％[17/44]vs.4.55％[2/44].P=0.002).Conclusion C-arm CT stent precision technique had obvious advantages for intracranial artery stent implantation.

Objective To investigate the effects of five-element music on depressive behaviors and intestinal flora in offspring of fear-stress rats during pregnancy.Methods Thirty-six 0.5-day pregnant Wistar rats were divided randomly into a control group,fear-stress group,and five-element music group,and the subsequent litters continued the maternal grouping.Pregnant rats in the fear-stress and five-element music groups were modeled on days 1～19 of gestation using the bystander electric method,while the five-element music group was also exposed to Feather Tune five-element music intervention.The fear behavior and serum glucocorticoid(GC)levels in pregnant rats were assessed on day 20 of pregnancy by open field test and enzyme-linked immunosorbent assay,respectively,to evaluate the effectiveness of the model.Depression in 3-week-old offspring was evaluated by open field,tail suspension,and sucrose preference tests.Norepinephrine(NE),dopamine(DA),and 5-hydroxytryptamine(5-HT)levels in the hippocampus of the offspring were measured by high-performance liquid chromatography.Changes in the intestinal flora of the offspring were analyzed by 16S rRNA sequencing.Expression levels of the proximal colonic proteins claudin1,occludin,and ZO1 in the offspring were measured by Western blot assay.Results Pregnant rats in the fear-stress group stayed longer in the area around the open field(P＜0.05),had fewer entries into the central area(P＜0.001),and had higher serum GC levels compared with those in the blank group(P＜0.001).In contrast,five-element music exposure reversed these behavioral changes(P＜0.05)and serum GC levels(P＜0.001)in the fear-stress group.Offspring in the fear-stress group exhibited decreased open-field crossing frequency(P＜0.01),reduced sucrose preference index,and longer immobility time in the tail suspension test(P＜0.05),compared with those in the blank group,together with significantly decreased NE,DA,and 5-HT levels in the hippocampus(P＜0.05).Rats in the fear-stress group showed decreased diversity of the intestinal flora(P＜0.01)and significant alterations in flora structure,including higher abundance of Proteobacteria,Enterobacteriaceae,Enterococcus,and Escherichia(P＜0.05),and lower abundance of Spirochaetes,Spirochaetaceae,Lachnospiraceae,Ruminococcaceae,Treponema,Prevotella,Coprococcus,Allobaculum,Ruminococcus,and Dorea(P＜0.05).The proximal colonic proteins Claudin1,Occludin,and ZO1 were significantly downregulated(P＜0.05).The open-field crossing frequency,sucrose preference index,and duration of tail suspension immobilization were improved in the five-element music group compared with those in the fear-stress group(P＜0.05),while DA and 5-HT levels were significantly restored in the hippocampus(P＜0.05),species diversity of the intestinal flora increased(P＜0.01)and changes in the abundance of the flora were reversed,and the proximal colonic proteins Occludin and ZO1 expression were significantly upregulated(P＜0.05).Conclusions Five-element music intervention during pregnancy can ameliorate fear-stress-induced depression behaviors and intestinal flora disorders in the offspring.

Objective:To evaluate the effect of thunder-fire moxibustion combined with fire-dragon cupping on patients with acute peripheral facial paralysis with co-morbid anxiety and depression.Methods:A total of 80 patients with acute peripheral facial paralysis with co-morbid anxiety and depression were selected and divided into two groups according to the random number table method,with 40 patients in each group.In the control group,acupuncture therapy combined with routine care was given;in the observation group,thunder-fire moxibustion and fire-dragon cupping therapy were added.Both groups were treated once a day,6 times a week,with 1 d of rest,for 4 consecutive weeks(a total of 24 treatments).The House-Brackmann(H-B)grading,facial clinimetric evaluation(FaCE),self-rating anxiety scale(SAS),and self-rating depression scale(SDS)were used before and after the intervention to evaluate the facial nerve function,quality of life,mental health,and clinical efficacy of the two groups.Results:After treatment,patients in both groups showed improvement in H-B grading,scores of all dimensions of the FaCE scale,and SAS and SDS scores compared to those before treatment,and the differences within the groups were statistically significant(P<0.05).After treatment,the total effective rate was 95.0%in the observation group and 75.0%in the control group,and the difference between the two groups was statistically significant(P<0.05).After treatment,the H-B grading of the observation group was better than that of the control group(P<0.05);the scores of all dimensions of the FaCE scale and SAS and SDS scores of the observation group were better than those of the control group(P<0.05).Conclusion:Adding thunder-fire moxibustion and fire-dragon cupping therapy to acupuncture and routine care can promote the recovery of facial nerve function,reduce anxiety and depression,and improve the patients'living standard,and thus is suitable for popularization and application.

Objective:To explore the characteristics of systemic immune microenvironment during the progression of dextran sulfate sodium(DSS)-induced acute ulcerative colitis(UC)induced in mice by Mass cytometry(CyTOF).Methods:Male C57BL/6 mice were randomly divided into control group and model group.The control group was given normal drinking water for 15 d.The mouse in the model group were given 5%DSS in drinking water,which was changed to normal drinking water after 7 days.In the model group,peripheral blood was collected on days 4,9 and 15,respectively.CyTOF was used to detect the expressions of 33 immune cell markers and changes in cell subsets in peripheral blood of mice,and the characteristics of systemic immune microenvironment in mice with acute UC were analyzed.Results:The cluster analysis of 33 kinds of immune cell markers showed that CD45+cells in peripheral blood of mice with DSS induced acute UC were divided into 23 fine subgroups,among which the proportions of B cell subgroup,T cell subgroup and neutrophil subgroup showed significant changes.A further dimensional reduction cluster analysis of T cell subsets found significant differences in the composition and proportion of the 10 identified T cell subsets.Conclusion:The systemic immune micro-environment map of mice with acute UC induced by DSS has been successfully constructed,and heterogeneity has been found in the systemic immune microenvironment of mice with acute UC.The changes and activation degree of T cell subpopulations are closely re-lated to disease progression and inflammation level.The results of this study provide theoretical basis for assisting the diagnosis,moni-toring the risk,progression,treatment and prognosis of acute UC.

Objective To identify co-expressed genes and potential comorbidity mechanisms between Alzheimer's disease(AD)and epilepsy with publicly available single-cell transcriptome sequencing data from human brains,fol-lowed by functional validation in APP/PS1 double transgenic AD mouse models expressing the chimerical Mo/HuAPP695swe amyloid precursor protein and mutant PS1-dE9 presenilin 1.Methods The single-cell transcriptome sequencing data of brain tissue from AD and epilepsy patients were collected from gene expression omnibus(GEO)database followed by cell clustering,differential expression analysis and gene ontology(GO)func-tional enrichment analysis using R-based tools such as Seurat and cluster Profiler and video electroencephalogram (vEEG)monitoring and Western blot experiments.Results A total of eight major brain cell types were identified,with neurons and glial cells exhibiting shared differentially expressed genes between AD and epilepsy.These co-ex-pressed genes were significantly clustered in pathways related to metal ion homeostasis,synaptic transmission,oxi-dative stress,and immune activation,which suggested common pathological mechanisms involving in synaptic dys-function and neuro-inflammation in both disorders.The vEEG recordings of APP/PS1 mouse model of AD showed 30％of mice exhibited high-frequency epileptic seizures,while 70％showed low-frequency seizure activity.Subse-quent validation in the prefrontal cortex of AD mice confirmed up-regulated expression of key molecular markers(HES5,c-FOS,and RPL10A)identified through single-cell sequencing analysis.Conclusions AD and epilepsy share gene co-expression profiles and functional pathways in specific cell types.The results of research provide a theoretical support for further elucidating their comorbidity mechanisms and developing targeted therapeutic strategy.
