This paper focuses on the formation of Chinese medicine symptoms in late-life depression(LLD).It delves into an interdisciplinary study that combines interoception and the Chinese medicine concept of'holism of physique and spirit'.LLD,as a common psychiatric disorder,has significant differences in clinical characteristics from younger patients,often manifesting physical discomfort and cognitive impairment.As a key link in the body-brain axis,interoception plays a central role in regulating emotions and behaviors,and its abnormalities are closely related to the development of LLD.The Chinese medicine concept of'holism of physique and spirit'provides a therapeutic perspective that unifies the body and the spirit,emphasizing the interaction between visceral functions and emotional states.Psychological interventions,including cognitive-behavioral therapy and mindfulness meditation,are effective in improving interoception and reducing depressive symptoms.In this study,the relationship between interoception and LLD was analyzed through embodied cognition theory and fMRI technology,and the application of'holism of physique and spirit'in treating late-life depression.The challenges and opportunities of interdisciplinary research in the field of late-life depression is discussed,and future research directions is proposed,aiming to provide more scientific and effective strategies for the prevention,diagnosis,and treatment of LLD.

Objective·To investigate the regulatory effects and underlying mechanisms of mouse mandibular osteoblasts on B cell differentiation and development.Methods·Single-cell suspensions from mouse mandibular bone were prepared using an optimized enzymatic digestion method and induced to differentiate into osteoblasts in vitro.Osteogenic potential was validated by real-time quantitative PCR(RT-qPCR),alkaline phosphatase(ALP)staining,and alizarin red S(ARS)staining.The spatial localization relationship between osteoblasts and B cells in mandibular tissues was examined via immunofluorescence staining.High-purity hematopoietic progenitor cells were isolated using fluorescence-activated cell sorting.A Transwell co-culture system was established to assess the regulatory effects of different osteoblast concentrations(5×104,2.5×105,and 5×105 cells/well)on B cell differentiation(5×104 cells/well).Flow cytometry and RT-qPCR were employed to evaluate B cell viability and differentiation.Additionally,RT-qPCR was used to analyze the expression of osteoblast-secreted factors associated with B cell development during osteogenic differentiation.Results·Mandibular osteoblasts exhibited robust osteogenic potential,as confirmed by ALP/ARS staining and high expression of osteogenic markers(Runx2,Osx,Ocn,and Alp)via RT-qPCR.Immunofluorescence revealed close spatial proximity between osteoblasts and B cells in mandibular tissues.In the co-culture system,osteoblasts promoted B cell differentiation in a concentration-dependent manner.RT-qPCR and immunofluorescence demonstrated that osteoblasts significantly upregulated key genes involved in B cell development(Ebf1,Rag1,Il7r,and Pax5;all P<0.001).Furthermore,osteoblast-derived factors(Il7,Baff,and Flt3l)were markedly elevated during osteogenic differentiation(all P<0.05).Conclusion·Mandibular osteoblasts enhance B cell differentiation and development in a concentration-dependent manner,likely through secreting growth factors that upregulate critical B cell differentiation genes.

Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

Objective:To study the effects of hypoxia on the autophagy level in the spleen of mice with OSAHS.Methods:Mouse OSAHS hypoxia model was established in 24 C57BL/6 mice and the mice were divided into 3 groups:normoxic group,hypoxic group and resveratrol group(n=8).Real time PCR,Western blot and immunohistochemical staining(IHC)were used to detect the mRNA and protein expression of autophagy related proteins microtube associated protein 1 light chain 3 B(LC3B),myosin-like BCL2 inteacting protein(Beclin1)and autophagy related gene 5(ATG5)in mouse spleen respectively.Results:The mRNA expres-sion of LC3B,Beclin1,and ATG5 in the hypoxic group was lower than that in the normoxic group(P＜0.01,P＜0.01,P＜0.001),resveratrol upregulated the expression levels of LC3B and ATG5 mRNA in the hypoxic group(P＜0.05,P＜0.001),but did not up-regulate the expression of Beclin1(P＞0.05).The protein expression levels of LC3B,Beclin1 and ATG5 in the hypoxic group were lower than that in the normoxic group(P＜0.05,P＜0.05,P＜0.01).Resveratrol upregulated the expression levels of LC3B and ATG5 in the hypoxic group(P＜0.05,P＜0.01),but did not upregulated the expression of Beclin1(P＞0.05).IHC test showed that the expression level of LC3B,Beclin1 and ATG5 in the hypoxic group was lower than that in the normoxic group(P＜0.01,P＜0.01,P＜0.001).Resveratrol increased the expression level of LC3B and ATG5 in the hypoxic group(P＜0.05,P＜0.01),but did not upregulate the expression of Beclin1(P＞0.05).Conclusion:Hypoxia may inhibite the autophagy level of spleen in mice.Resvera-trol derivatives increases the autophagy level of mice under hypoxia condition,but has no significant effect on Beclin1 expression.

Objective To investigate the current status of breastfeeding motivation in early post-partum women and analyze the influencing factors of breastfeeding motivation.Methods A conven-ience sampling method was used to select 205 hospitalized women within 48 to 72 hours postpartum as the study subjects.The women were surveyed using a general information questionnaire,a breastfeed-ing motivation scale,a breastfeeding knowledge questionnaire,and a short-form scale for breastfeed-ing self-efficacy.Multiple linear regression analysis was conducted to explore the influencing factors of breastfeeding motivation among the women.Results The average score for autonomous motivation to-wards breastfeeding among 205 women was(49.94±7.62),and the average score for controlled mo-tivation was(23.76±3.59).The results of multiple linear regression analysis showed that age,par-ticipation in breastfeeding-related courses during pregnancy,planned duration of breastfeeding,skill dimension score of the short-form scale for breastfeeding self-efficacy,and total score on the breast-feeding knowledge questionnaire were influencing factors for the autonomous motivation score towards breastfeeding(P＜0.05);participation in breastfeeding-related courses during pregnancy,skill di-mension score on the short-form breastfeeding self-efficacy,and total score on the breastfeeding knowledge questionnaire were influencing factors for the controlled motivation score towards breast-feeding(P＜0.05).Conclusion The level of breastfeeding motivation in early postpartum women needs to be improved.Healthcare providers should focus on maternal age and planned duration of breastfeeding,strengthen breastfeeding knowledge education,and enhance maternal breastfeeding self-efficacy to improve maternal breastfeeding motivation and breastfeeding rates.

Objective:To explore the effects of Baduanjin and brisk walking on the sleep quality among fe-male college students.Methods:Ninety female college students with poor sleep quality[Pittsburgh Sleep Quality Index(PSQI)≥ 8]were recruited randomly assigned to Baduanjin,brisk walking,and control groups,with 30 par-ticipants in each.The Baduanjin and brisk walking groups participated in 10-week intervention(five 45-minute ses-sions per week),while the control group did not receive any intervention.Baseline and post-intervention assessments were conducted using the PSQI,a lung capacity test,echocardiography,and the Fatigue Scale(FS-14).Results:Af-ter 10 weeks,participants in both the Baduanjin and brisk walking groups got significantly lower PSQI and FS-14 total scores compared to baseline(Ps＜0.001).Cardiopulmonary function indicators,including stroke volume(SV),forced expiratory volume in one second(FEV1.0),the vital capacity-to-body mass index(VC/W),and maximum voluntary ventilation per minute(MVV),also significantly improved(Ps＜0.001).Furthermore,the Baduanjin group had significantly lower PSQI and FS-14 scores than both the brisk walking and control groups(P＜0.001),along with superior improvements in cardiopulmonary function(P＜0.001).Conclusion:This study in-dicates that Baduanjin is particularly effective in improving sleep quality,cardiopulmonary function,and reducing fatigue among female college students,showing advantages over brisk walking.

Objective To investigate the value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced MRI radiomics and signal intensity in hepatobiliary phase(HBP)in predicting the pathological differentiation degree of hep-atocellular carcinoma(HCC).Methods The clinical and imaging data of 224 patients pathologically confirmed with HCC were col-lected.All patients were randomly divided into test group(68 cases)and training group(156 cases)at a ratio of 7︰3.The ITK-SNAP software was used to delineate region of interest(ROI)on arterial phase(AP),portal venous phase(PVP)and HBP,the radiomics features of the tumor tissues were extracted and the radiomics models were established using the FAE software.Logistic regression analysis was used to determine the clinical independent predictors associated with the pathological differentiation degree of HCC and to construct clinical model and clinical-radiomics model.Receiver operating characteristic(ROC)curve was plotted for each model and the area under the curve(AUC)was calculated to compare the diagnostic efficacy of the models.Results Age,alpha-fetoprotein(AFP),and r-glutamyltransferase(r-GT)were independent risk factors for predicting the degree of pathological differentiation of HCC.The AUC of the clinical-radiomics model in the training group and test group were 0.825 and 0.779,respectively,which were higher than those of the radiomics model(0.812 and 0.771)and the clinical model(0.687 and 0.666).Conclusion Gd-EOB-DTPA enhanced MRI radiomics have certain value in predicting the degree of pathological differentiation of HCC,while the predictive value of the signal intensity on HBP and the signal intensity ratio(SIR)on HBP is limited.

Objective:To compare the effect of repeated transcranial magnetic stimulation (rTMS) targeting the M1 hand area, the M1 lower limb area, or the sciatic nerve on the motor functioning and ability in the activities of daily living of persons after a spinal cord injury (SCI).Methods:This was a retrospective analysis of data describing 86 hospitalized SCI patients. They were divided into four groups based on where the rTMS was applied: an M1 hand area group ( n=22), an M1 lower limb area group ( n=20), a sciatic nerve group ( n=24), and a control group ( n=20) who never received rTMS. In addition to conventional medication and rehabilitation training, the M1 hand area group, the M1 lower limb area group and the sciatic nerve group received 10Hz rTMS over the named area for 4 weeks. Before and after the treatment, the Spinal Cord Independence Measure (SCIM) total scores, SCIM indoor activity (SCIM12) sub-scores, Modified Barthel Index (MBI) scores, and lower extremity motor (LEMS) scores were compared among the four groups. Results:After the treatment, the average SCIM, SCIM12, MBI, and LEMS scores had improved significantly in all four groups. The average SCIM [10.00(4.00, 24.75] and MBI scores [12.00(6.75, 31.50)] of the M1 hand area group were then significantly better than the control group′s averages [3.50(0.00, 9.50) and 7.50(1.25, 17.75)]. There was also significantly greater improvement in the average LEMS score of the M1 hand area group [2.00(0.00, 10.00)] compared with both the sciatic nerve group [0.00(0.00, 2.00)] and the control group [0.00(0.00, 1.75)].Conclusions:High-frequency rTMS stimulation of the M1 hand area significantly promotes the recovery of lower limb motor function and self-care ability after an SCI. It is more effective than stimulating the M1 lower limb area or the sciatic nerve.

Objective:To analysis the possible behavior of coders in the reform of Diagnosis Related Groups(DRG)payment mode.Methods:To collect through questionnaires the possible coders'behaviors,and extract the common factors of possible behaviors according to factor analysis,and cluster the coders by the K-means clustering method.Results:Classify the possible coders'behaviors into positive behaviors such as following coding norms and standards,and negative behaviors such as directly coding without detailed reading of medical records.Less than 25 years old were more inclined to adopt negative behaviors,and associate senior titles and higher cognitive level of DRG were more inclined to adopt positive behaviors.The coders are divided into"positive group"who tend to take positive behaviors and"negative group"who take negative behaviors.Conclusion:Coders are more likely to adopt positive behavior,and we should be pay attention to the impact of different demographic characteristics on coders.To adopt different management strategies for different categories of coders,and strengthen training through hierarchical classification,and enhance coders'cognitive of DRG are more conducive to the selection of positive behaviors.
