Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

[摘 要] 目的：基于公开的卵巢癌（OC）单细胞测序数据并利用生物信息学方法构建OC上皮细胞亚型，探究上皮细胞异质性及其对OC肿瘤微环境（TME）的影响。方法：使用GSE118828卵巢癌单细胞数据集的分析得到的8种细胞类型及基因表达矩阵结果，使用反卷积方法估计整体转录组测序（bulk RNA-seq）数据中的细胞组成，依据上皮细胞丰度将OC分为高上皮细胞亚型（C1型）和低上皮细胞亚型（C2型）。分析C1型与C2型患者的生存时间及免疫微环境差异。基于C1、C2型及OC早期（Ⅰ~Ⅱ期）、晚期（Ⅲ~Ⅳ期）组间的差异表达基因（DEG），筛选与OC进展相关的上皮细胞相关基因并分析其对TME的影响。通过人类蛋白质图谱（HPA）数据库数据验证OC进展中上皮细胞相关基因的蛋白表达水平。结果：C1型患者的OS明显优于C2型患者（P < 0.05）。C1、C2型具有完全不同的免疫微环境浸润特性，C1型中辅助性T（Th）细胞、M1型巨噬细胞和激活的树突状细胞浸润程度显著高于C2型（均P < 0.05）。晚期高上皮细胞OC患者HAS1、DAPL1、ADH1B基因表达增加（均P < 0.05），同时，DAPL1基因在OC中的表达与巨噬细胞、Treg细胞的浸润程度呈正相关（P < 0.05）。HPA数据库数据证实，DAPL1蛋白在OC组织中表达显著增加。结论：卵巢癌高上皮细胞亚型可能由于Th细胞、M1型巨噬细胞和激活的树突状细胞的高度浸润发挥抗肿瘤作用；上皮细胞相关基因DAPL1的高表达可能会诱导巨噬细胞、Treg细胞的浸润程度，从而促进OC的进展。

Lower extremity arteriosclerosis obliterans(LEASO)is a disease characterized by the formation of atherosclerotic plaques in the lower extremity arteries,leading to arterial stenosis,occlusion,and consequent chronic limb ischemia.This article analyzes the clinical data of a patient with LEASO complicated by an iodine contrast agent allergy,along with the treatment involving intravascular ultrasound(IVUS)-guided endovascular intervention performed without contrast agent,and reviews relevant literature.The patient,a 53-year-old female,presented with coldness and numbness in the left lower extremity and pain after walking for 2 years,symptoms which had worsened over the past 2 months,with a maximum claudication distance of less than 50 meters.The lower extremity arterial CT angiography(CTA)results indicated"left iliac artery occlusion and left superficial femoral artery stenosis."After examination,the patient exhibited allergic symptoms.Upon admission,other diseases were ruled out.Given that the lower extremity symptoms severely impacted the patient's daily life and considering the potential for contrast agent allergy,the use of contrast agent was abandoned.IVUS guidance alone was employed to assess the intravascular condition for the interventional procedure.The surgical interventions chosen were drug-coated balloon angioplasty of the left superficial femoral artery and stent implantation in the left iliac artery.Postoperatively,the patient was able to walk normally,the discomfort resolved,and the treatment outcome was satisfactory.For LEASO patients with contrast agent allergy or other contraindications to contrast use,the sole use of IVUS guidance combined with invasive blood pressure monitoring to intraoperatively assess efficacy can effectively avoid contrast agent administration,providing a valuable reference for clinicians managing such cases.

Objective To compare the efficacy and adherence of rivaroxaban versus low-molecular-weight heparin for prophylactic anticoagulation in cancer patients with venous thromboembolism(VTE).Methods A total of 120 intermediate-to-high VTE risk patients with malignant tumors admitted to Depart-ment of Hematology and Oncology,West China Longquan Hospital of Sichuan University between September 2021 and December 2022,were randomly assigned to the rivaroxaban group(n=60)and the low-molecular-weight heparin group(n=60)using the random number table.The rivaroxaban group received oral Rivaroxa-ban,while the low-molecular-weight heparin group received subcutaneous injections of low-molecular-weight heparin sodium for prophylactic anticoagulation.All patients were followed up for 180 days.The primary end-point was medication adherence.The secondary endpoints included the incidence of VTE,bleeding events,and changes in coagulation parameters.Results The rate of good medication adherence was significantly higher in the rivaroxaban group than in the low-molecular-weight heparin group(95.00％vs.88.33％,P＜0.05).However,there were no statistically significant differences in the incidence of VTE or overall bleeding events between the two groups(P＜0.05).Following treatment,parameters including fibrinogen,prothrombin time(PT),and D-dimer levels showed significant improvement from baseline in both groups.Compared to the low-molecular-weight heparin group,the Rivaroxaban group demonstrated significantly higher fibrinogen levels,shorter PT,and lower D-dimer levels(P＜0.05).Stepwise logistic regression analysis identified the post-treatment platelet(PLT)count as a significant factor influencing bleeding events during prophylactic antico-agulation(P＜0.05).Khorana score≥3(high risk)was identified as a risk factor for bleeding events(P＜0.05).The incidence of clinically relevant non-major bleeding(CRNMB)was higher in the rivaroxaban group[11.67％(7/60)]compared to the low-molecular-weight heparin group[8.33％(5/60)],although the differ-ence was not statistically significant(P＜0.05).Kaplan-Meier curve analysis revealed no significant difference in the cumulative incidence of bleeding-free events between the two groups(P＜0.05).Conclusion Oral ri-varoxaban and subcutaneous low-molecular-weight heparin demonstrate comparable efficacy and safety for VTE prevention in cancer patients,but rivaroxaban significantly improves patient's adherence.

Objective To understand the latent profiles of kinesiophobia in kidney transplant recipients and explore the influencing factors of different profiles.Methods A cross-sectional study was conducted on 230 kidney transplant recipients subjected with convenient sampling from Department of Nephrology,the First Affiliated Hospital of Army Medical University from November 2024 to February 2025.General Information Questionnaire,Tampa Scale of Kinesiophobia-11(TSK-11),Exercise Compliance Questionnaire,Fatigue Scale-14(FS-14),Patient Health Questionnaire-9(PHQ-9)and Chinese Version of the Self-Efficacy to Manage Chronic Disease Scale(C-SEMCD)were used for investigation and latent profile analysis.Univariate analysis and logistic regression analysis were applied to explore the influencing factors of different profiles.Results Kinesiophobia in the participants was classified into 3 latent profiles:fearless movement type-low kinesiophobia group(54 cases,23.48%),cautious movement type-moderate kinesiophobia group(98 cases,42.61%),and resistant movement type-high kinesiophobia group(78 cases,33.91%).Statistical differences were observed among the 3 groups in terms of age,education level,post-operative duration,depression score,fatigue score,and self-efficacy score of chronic disease management(P<0.05).Logistic regression analysis showed that age(OR=8.82,95%CI:1.27～61.10),education level[junior high school or below(OR=0.14,95%CI:0.04～0.50);technical secondary school or senior high school(OR=0.08,95%CI:0.02～0.27)],post-operative duration[<1 year(OR=11.39,95%CI:2.53～51.30);1-5 years(OR=11.05,95%CI:2.48～49.22)],fatigue(OR=1.32,95%CI:1.10～1.59),and depression(OR=1.53,95%CI:1.19～1.98)were influencing factors for resistant movement type-high kinesiophobia in the kidney transplant recipients.Education level(technical secondary school or senior high school:OR=0.32,95%CI:0.12-0.86)and self-efficacy of chronic disease management(OR=0.95,95%CI:0.90-1.00)were influencing factors for cautious movement type-moderate kinesiophobia in the recipients.Conclusion Kinesiophobia in kidney transplant recipients can be classified into 3 latent profiles.Recipients'age,education level,post-operative duration,fatigue,and depression are influencing factors for the resistant movement type-high kinesiophobia,and education level and chronic disease management self-efficacy are important influencing factors for the cautious movement type-moderate kinesiophobia.

Objective:To observe the efficacy and safety of combined lienal polypeptide injection therapy in the treatment of Mycoplasma pneumoniae pneumonia（MPP）in children aged 3 to 14 years old in multiple clinical centers.Methods:A randomized，controlled，multi-center clinical study design was adopted.A total of 240 hospitalized children aged 3 to 14 years old with MPP from 7 hospitals from September 1，2023 to January 31，2024 were included.According to the severity of pneumonia，they were divided into the mild MPP group with 80 cases and the severe MPP/refractory MPP（SMPP/RMPP）group with 160 cases，and then randomly divided into the control group and the experimental group at a ratio of 1 ∶1，using the random number table method.After screening，subjects entered a treatment period of 5 to 7 days.The control group was treated with azithromycin，while the experimental group was treated with azithromycin plus lienal polypeptide injection .The recovery of lung CT，length of hospital stay，duration of fever，cough score，whether mild cases developed into severe or refractory cases，duration of hormone use，use of intravenous immunoglobulin（IVIG），bronchoscopy treatment，and immune function were observed between the two groups to evaluate the efficacy of lienal polypeptide injection.Adverse events after medication，vital signs，blood routine，urine routine，liver function，myocardial enzymes，renal function，and electrocardiogram were observed to evaluate the safety. Results:A total of 231 subjects have completed the trial in the 7 hospitals，including 118 cases in the experimental group and 113 cases in the control group.Main observation index：the rate of lung CT aggravation in the experimental group was lower than that in the control group（2.6% vs 15.3%， P<0.01），and the difference was statistically significant.Secondary indexes：there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.However，the rate of cases of plastic bronchitis（PB）found under bronchoscopy in the experimental group was lower than that in the control group（0 vs 18.8%， P=0.03），and the difference was statistically significant.Among the mild MPP（72 cases），there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and the improvement rate of lung CT between the two groups（all P>0.05）.However，compared with the control group，the rate of cases developing into SMPP/RMPP in the experimental group was less（24.3% vs 48.6%， P=0.03），and the difference in IgG before and after treatment was small［0.53（-0.04，1.18）g/L vs 1.33（0.48，2.25）g/L， P=0.01］.Among the SMPP/RMPP cases（159 cases），the rate of cases of PB found under bronchoscopy in the experimental group was less than that in the control group（0 vs 20%， P=0.04），and the rate of cases with aggravated lung CT in the experimental group was less than that in the control group（1.3% vs 19.5%， P<0.01），and the improvement rate of lung CT in the experimental group was higher than that in the control group（88.8% vs 75.3%， P=0.03），with statistically significant differences.There were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.Two cases in the experimental group developed rashes，which improved after the drug was discontinued.There were no serious adverse reactions such as abnormal vital signs like dyspnea and cyanosis due to the use of lienal polypeptide injection.There were no obvious changes in blood routine，liver function，myocardial enzymes，renal function，electrocardiogram，and urine routine values before and after medication compared with the baseline. Conclusion:The combined use of lienal polypeptide injection in the treatment of MPP in children can reduce the probability of the transformation from mild cases to SMPP/RMPP，reduce the rate of aggravation of the image findings，promote the absorption of lung inflammation，reduce the rate of PB found under bronchoscopy，and has good safety.

Objective To investigate the relationship between serum glucagon-like peptide-1(GLP-1),monocyte chemoattractant protein-1(MCP-1),insulin-like growth factor binding protein-3(IGFBP-3)and glycolipid metabolism,bone metabolism and microvascular complications(MC)in children with type 1 diabe-tes mellitus(T1DM).Methods A total of 211 children with T1DM(T1DM group)admitted to Handan Cen-tral Hospital,Xingtai Traditional Chinese Medicine Hospital,Baoding First Central Hospital and Handan Ma-ternal and Child Health Hospital from January 2021 to February 2023 were selected,patients were divided into MC group(63 cases)and non-MC group(148 cases)according to whether MC was complicated within 1 year,and 108 healthy children who underwent physical examination during the same period were selected as control group.The levels of serum GLP-1,MCP-1,IGFBP-3 and glucose and lipid metabolism indexes[fasting plasma glucose(FPG),fasting insulin(FINS),glycosylated hemoglobin(HbA1c),homeostasis model assessment of insulin resistance(HOMA-IR),total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)]and bone metabolism indexes[bone specific alkaline phosphatase(BALP),osteocalcin(OST),type I collagen cross-linked C-terminal peptide(CTX)]were detec-ted.The correlation between serum GLP-1,MCP-1,IGFBP-3 and glucose and lipid metabolism,bone metabo-lism in children with T1DM were analyzed by Pearson and Spearman correlation coefficient.Taking MC in children with T1DM as the dependent variable,the influencing factors were determined by multivariate uncon-ditional Logistic regression model,and the predictive value of serum GLP-1,MCP-1 and IGFBP-3 for MC were analyzed by receiver operating characteristic curve.Results The levels of serum GLP-1,FINS,HDL-C,BALP,OST and CTX in the T1DM group were lower than those in the control group,while the levels of MCP-1,IGFBP-3,FPG,HbA1c,HOMA-IR,TG and LDL-C in the T1DM group were higher than those in the control group,the differences were statistically significant(P<0.05).Serum GLP-1 in children with T1DM was negatively correlated with FPG,HbA1c,HOMA-IR,TG and LDL-C,and positively correlated with FINS,HDL-C,BALP,OST and CTX(P<0.05).MCP-1 and IGFBP-3 were positively correlated with FPG,HbA1c,HOMA-IR,TG and LDL-C,and negatively correlated with FINS,HDL-C,BALP,OST and CTX(P<0.05).Follow-up for 1 year,the incidence of MC in 211 children with T1DM was 29.86%(63/211).Elevated HbA1c,HOMA-IR,LDL-C,MCP-1 and IGFBP-3 were independent risk factors for MC in children with T1DM,and elevated GLP-1 was an independent protective factor(P<0.05).The area under the curve of ser-um GLP-1,MCP-1 and IGFBP-3 combined to predict MC in children with T1DM was 0.919,which was grea-ter than 0.781,0.788 and 0.794 predicted by serum GLP-1,MCP-1 and IGFBP-3 alone(P<0.05).Conclu-sion The decrease of serum GLP-1 level and the increase of MCP-1 and IGFBP-3 levels are related to glyco-lipid metabolism,bone metabolism disorder and MC in children with T1DM,the combined application of ser-um GLP-1,MCP-1 and IGFBP-3 has a good predictive value for MC in children with T1DM.

Objective:To investigate the effects and mechanism of Shenshuaikang Enema on hypoxia/reoxygenation (H/R) NRK-52E cells; To provide references for Shenshuaikang Enema to treat AKI.Methods:The H/R-induced NRK-52E cell model was established, and control group, model group, drug-containing serum group, drug-containing blood group +p53 agonist group, p53 agonist group, p53 inhibitor group were set up. Cell viability was detected by CCK8. The cell cycle distribution in each group was analyzed using flow cytometry, while cell senescence was assessed via β-galactosidase staining. The levels of IL-6, IL-1β, and TNF-α in the cell supernatant were evaluated using ELISA. Western Blot analyses were conducted to measure the protein expressions of p53, phosphorylated p53 (p-p53), and p21.Results:Compared with model group, NRK-52E cell vitality significantly increased in the drug-containing serum group and p53 inhibitor group ( P<0.01, P<0.05), S phase and G2/M phase percentage was significantly reduced ( P<0.01), β-galactoase staining decreased ( P<0.01), the levels of IL-1β, IL-6 and TNF-α decreased ( P<0.05, P<0.01), the protein expressions of p-p53 and p21 decreased ( P<0.01). Compared with the drug-containing serum group, NRK-52E cell vitality significantly decreased in the drug-containing serum+p53 agonist group and p53 agonist group ( P<0.01), S phase and G2/M phase percentage was significantly increased ( P<0.01), β-galactoase staining increased ( P<0.01), the levels of IL-1β, IL-6 and TNF-α increased ( P<0.01), the protein expressions of p-p53 and p21 increased ( P<0.01 or P<0.05). Conclusion:The drug-containing serum of Shenshuaikang Enema may promote cell proliferation, improve cell cycle arrest, inhibit pro-inflammatory and senescence related secretory phenotypes, and inhibit cell senescence by inhibiting p53/p21 signaling pathway, so as to promote H/ R-induced NRK-52E cell damage repair.

Objective To identify latent classes of medication adherence change trajectories in middle-aged and young patients with hypertension based on the Latent Growth Mixture Modeling(LGMM)and analyze its influencing factors.Methods A convenience sampling method was used to select 258 middle-aged and young patients with hypertension as study subjects.A cross-sectional sur-vey was conducted on their general information,medication beliefs,self-management behaviors,and Family Care Index.Medication adherence was assessed one day before discharge(T0),one month after discharge(T1),three months after discharge(T2),and six months after discharge(T3).LGMM was used to identify latent classes of change trajectories,and univariate analysis and multivari-ate Logistic regression analysis were conducted to explore the influencing factors.Results After ex-cluding 30 invalid data,228 patients were ultimately included in this study.LGMM fitting results showed that medication adherence change trajectories comprised three latent classes:low adherence-fluctuating group(31.58％),medium adherence-continuously increasing group(32.46％),and high adherence-gradually declining group(35.96％).Multivariate Logistic regression analysis results indi-cated that age,medication types,medication belief scores,self-management behavior scores,and Fam-ily Care Index scores were all independent influencing factors for latent classes of medication adherence change trajectories in middle-aged and young patients with hypertension(P＜0.05).Conclusion There is significant population heterogeneity in medication adherence among middle-aged and young pa-tients with hypertension,with varying change trajectories observed.Healthcare professionals should identify target populations early and formulate targeted intervention programs based on the influen-cing factors of different latent classes to effectively improve patients' medication adherence.
