ObjectiveTo evaluate the clinical efficacy of Xu's Shenqiyizhu （SQYZ） decoction combined with chemotherapy in the treatment of cancer-related fatigue （CRF） of stagnated-toxin spleen deficiency type after gastric cancer surgery and explore its possible mechanism. MethodsFifty postoperative gastric cancer patients with CRF of stagnated-toxin spleen deficiency type were selected and randomly divided into an experimental group and a control group by using a random number table，with 25 cases in each group. The control group was treated with FLOT chemotherapy （50 mg·m^-2 docetaxel （iv drip on day 1） + 85 mg·m^-2 oxaliplatin （iv drip on day 1） + 200 mg·m^-2 calcium folinate （iv drip on day 1） + 2 600 mg·m^-2 fluorouracil （iv drip for 24 h on day 1），once every three weeks） and basic and symptomatic supportive treatment. The experimental group was treated with Xu's SQYZ decoction （decocted twice，200 mL taken orally twice a day） in addition to the treatment of the control group. One course of treatment lasted for three weeks，with a total of four courses conducted. Observation was performed on the piper fatigue scale （PFS） scores，karnofsky performance status （KPS） scores，European Organization for Research and Treatment of cancer quality of life questionnaire （EORTC QLQ-C30） scores，traditional Chinese medicine syndrome scores，and serum levels of tumor necrosis factor-α （TNF-α），interferon-γ （IFN-γ），and interleukin-6 （IL-6）detected via enzyme linked immunosorbent assay （ELISA） before and after treatment in the two groups. The safety test results before and after treatment for the two groups of patients，as well as the occurrence of adverse events during treatment， were recorded. Transcriptome sequencing data of peripheral blood samples from gastric adenocarcinoma patients and normal individuals were downloaded from the gene expression omnibus （GEO） database，and differentially expressed genes between the tumor and normal groups were identified. Differential gene enrichment analysis was made based on the Kyoto Encyclopedia of Genes and Genomes （KEGG） and Gene Ontology （GO）. The CRF relevance scores of genes were retrieved from the GeneCards database. Results① Compared with that before treatment，the total PFS score in the experimental group was significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group showed significantly reduced total PFS score （P<0.05）. ② Compared with that before treatment，the KPS score in the experimental group decreased significantly （P<0.05）. Compared with the control group after treatment，the experimental group exhibited a significantly decreased KPS score （P<0.05）. The experimental group demonstrated significantly increased functional scores （physical function，role function，emotional function，social function，and overall health） （P<0.05） and significantly reduced symptom scores （fatigue，shortness of breath，loss of appetite，constipation，and diarrhea） of the EORTC QLQ-C30 scale after treatment compared with before treatment. Compared with the control group after treatment，the experimental group presented significantly increased functional scores （physical function，emotional function，social function，and overall health） （P<0.05） and significantly reduced symptom scores （fatigue，nausea and vomiting，shortness of breath，loss of appetite，and diarrhea） of the EORTC QLQ-C30 scale （P<0.05）. Compared with those before treatment，the traditional Chinese medicine syndrome scores （eating too little and poor digestion，fatigue and weakness，postprandial bloating，abnormal bowel movements，lassitude and weakness，and total score） in the experimental group were significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group had significantly reduced traditional Chinese medicine syndrome scores （eating too little and poor digestion，fatigue and weakness，nausea and vomiting，and sallow complexion） （P<0.05）， which indicated better efficacy in the experimental group than in the control group （χ²=7.996，P<0.05）. The serum levels of TNF-α，IL-6，and IFN-γ were significantly correlated with each other （P<0.01）. Compared with those before treatment，the levels of serum cytokines TNF-α，IL-6，and IFN-γ in the experimental group were significantly reduced （P<0.05）. Compared with the control group after treatment，the experimental group showed significantly reduced serum levels of cytokines TNF-α，IL-6，and IFN-γ （P<0.05）. ③ There were no significant intra-group and inter-group differences in the safety test results of the two groups before and after treatment. During the treatment period，there was no significant difference in the incidence of adverse reactions between the two groups of patients. ④ Compared with the normal group，the tumor group exhibited a total of 328 significantly up-regulated genes in the peripheral blood （P<0.05），and KEGG and GO analyses showed that they were significantly enriched in signaling pathways such as TNF （P<0.05）. ⑤ TNF，IL6，IFNG， and other cytokine encoding genes may be key pathogenic genes for CRF. ConclusionXu's SQYZ decoction can alleviate symptoms such as fatigue in postoperative chemotherapy patients with gastric cancer and improve their functional status and quality of life. Its mechanism may be related to improving cytokine imbalance.

Peri-implant diseases are characterized by the resorption of hard tissue and the inflammation of soft tissue. Epigenetics refers to alterations in the expression of genes that are not encoded in the DNA sequence, influencing diverse physiological activities, including immune response, inflammation, and bone metabolism. Epigenetic modifications can lead to tissue-specific gene expression variations among individuals and may initiate or exacerbate inflammation and disease predisposition. However, the impact of these factors on peri-implantitis remains inconclusive. To address this gap, we conducted a comprehensive review to investigate the associations between epigenetic mechanisms and peri-implantitis, specifically focusing on DNA methylation and microRNAs (miRNAs or miRs). We searched for relevant literature on PubMed, Web of Science, Scopus, and Google Scholar with keywords including "epigenetics," "peri-implantitis," "DNA methylation," and "microRNA." DNA methylation and miRNAs present a dynamic epigenetic mechanism operating around implants. Epigenetic modifications of genes related to inflammation and osteogenesis provide a new perspective for understanding how local and environmental factors influence the pathogenesis of peri-implantitis. In addition, we assessed the potential application of DNA methylation and miRNAs in the prevention, diagnosis, and treatment of peri-implantitis, aiming to provide a foundation for future studies to explore potential therapeutic targets and develop more effective management strategies for this condition. These findings also have broader implications for understanding the pathogenesis of other inflammation-related oral diseases like periodontitis.

Objective: To investigate the aberrant alterations of microRNAs ( miRNAs) in exosomes derived from bone marrow stromal cells ( BMSCs) in the bone marrow supernatants of patients with acute myeloid leukemia (AML) and their impact on the prognosis of AML patients . Methods: Bone marrow supernatant samples were col- lected from three AML patients and three healthy donors . Exosomes were isolated using a commercial kit , identif- ying the morphology and marker expression , and subjected to miRNA sequencing to determine differentially ex- pressed miRNAs (DE-miRNAs) . The DE-miRNAs were then intersected with the exosomal miRNA expression pro- files of primary AML cells (GSE64029) to exclude AML cell - derived signals and to identify BMSC-derived DE - miRNAs . Subsequently , candidate miRNAs were identified through Cox regression and Lasso regression analyses based on data from The Cancer Genome Atlas (TCGA) . A prognostic risk model for AML was constructed , and pa- tients were stratified into high-risk and low-risk groups according to the median risk score . The prognostic value and clinical relevance of the model were further validated . Finally , the target genes of the candidate miRNAs were pre- dicted , followed by pathway enrichment analysis , construction of key regulatory networks , and correlation analysis between the expression levels of key miRNAs and their corresponding target genes . Results: Isolated exosomes ex- hibited a typical cup-shaped morphology with intact structures with particle size of 30 - 150 nm , and expressed exo- somal markers CD63 , ALIX , and TSG101 . miRNA sequencing identified 103 DE-miRNAs in AML patients com- pared with healthy donors; after intersection with the GSE64029 dataset , 83 BMSC-derived DE-miRNAs were re- tained . Among these , five candidate miRNAs ( miR-25-3p , miR-532-5p , miR-194-5p , miR-10a-5p , and miR- 20a-5p) were used to construct the prognostic model . Kaplan-Meier survival analysis demonstrated significantly lon- ger overall survival in the low-risk group compared with the high-risk group (P < 0. 05) . The areas under the ROC curve for the training/validation cohorts were 0. 80/0. 74 , 0. 80/0. 78 , and 0. 79/0. 64 at 1 , 2 , and 3 years , re- spectively . The prognostic model was significantly associated with risk stratification , patient age , and FAB classifi- cation (P < 0. 05) . KEGG pathway enrichment revealed that target genes of the candidate miRNAs were closely linked to cancer-related signaling pathways , including hepatocellular carcinoma , breast cancer , and non-small cell lung cancer. Correlation analysis indicated that the candidate miRNAs were significantly associated with key genes such as HIF1A , CREB1 , PIK3CA , IGF1R , PIK3R1 , TIAM1 , CRK , and PTEN (P < 0. 05) . Conclusion AML patients exhibit distinct miRNA expression profiles in BMSC-derived exosomes . A five-miRNA signature ( miR-25 - 3p , miR-532-5p , miR-194-5p , miR-10a-5p , and miR-20a-5p) demonstrates robust prognostic performance , sup- porting its potential clinical utility in risk stratification and outcome prediction for AML.

Colorectal cancer （CRC）， a most common malignant tumor of the digestive tract， is often manifested by abdominal pain， changes in stool quality， blood in the stool， and weight loss， with rising morbidity and mortality year by year. The onset and development of CRC involve a variety of mechanisms， in which tumor microenvironment （TME） and tumor-associated macrophages （TAMs） have received increasing attention. TAMs influence the tumor development via immune escape and angiogenesis promotion and are associated with the prognosis of tumors. In recent years， traditional Chinese medicine （TCM） has been widely researched and applied in the treatment of cancers. Studies have discovered that TCM mainly exerts the therapeutic effects on CRC by inhibiting the proliferation， metastasis， and angiogenesis， promoting the apoptosis， and inducing autophagy of tumor cells and boosting the immune function. TCM as an effective treatment approach can regulate TAMs to inhibit tumor growth. Moreover， the active components and targets of TCM can be taken as new research directions of immunotherapy. This review describes TAMs and their roles in CRC progression and summarizes the molecular targets and mechanisms of different active components， compound prescriptions， and novel preparations of TCM against CRC， aiming to provide a mechanism reference for the clinical treatment of CRC with TCM and give new insights into the in-depth research on the prevention and treatment of CRC-related diseases with TCM.

ObjectiveBy starting with the combination of Os Draconis， Bupleuri Radix， and Ostreae Concha， the role of mineral medicine Os Draconis in the combination of the Bupleuri Radix-containing tri-herbal medicines was preliminarily explored from the perspective of supramolecular system formation. Method① The appearance and Tyndall phenomenon of single decoction of Os Draconis， Bupleuri Radix， and Ostreae Concha， as well as co-decoction of Bupleuri Radix-Os Draconis， Bupleuri Radix-Os Draconis-Ostreae Concha， and Bupleuri Radix-Ostreae Concha were observed， and the average particle size， dispersion coefficient， and Zeta potential of suspension particles in each decoction were determined. The micromorphology of supramolecular structures was observed by scanning electron microscope （SEM）. ② The pH of different compatibility systems， liquid viscosity coefficient， liquid surface tension， freeze-dried powder yield rate， and other physical properties were determined， and the interaction of different compatibility systems was detected by infrared absorption spectroscopy （FTIR） and UV-visible spectrophotometry （UV-Vis）. ③ The composition and content difference of different compatible systems were determined by high-performance liquid chromatography （HPLC） and ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry （UPLC-Q-TOF-MS）. ResultCompared with the single decoction， the co-decoction had more obvious turbidity and Tyndall phenomenon. The particles in the co-decoction suspension were smaller and more evenly distributed， and the Zeta potential was reduced， indicating a more stable system. Under SEM， Bupleuri Radix was irregularly lamellar， and Bupleuri Radix-Os Draconis and Bupleuri Radix-Os Draconis-Ostreae Concha were mainly spherical nanoparticles. Bupleuri Radix-Ostreae Concha was irregularly lamellar， with a small number of spherical nanoparticles. The pH of the single decoction of Bupleuri Radix and co-decoction increased， and the viscosity coefficient increased. The liquid surface tension decreased. The freeze-dried powder yield rate of the Bupleuri Radix-Os Draconis co-decoction was the highest， followed by Bupleuri Radix-Ostreae Concha decoction and Bupleuri Radix-Os Draconis-Ostreae Concha decoction， and the yield rate of Bupleuri Radix single decoction was the lowest. The main change of FTIR was the stretching vibration of -OH， and the co-decoction moved to the low-frequency direction obviously. UV-Vis showed that the maximum absorption occurred at 295.8 nm for all groups， and the absorption intensity was different （Bupleuri Radix-Os Draconis>Bupleuri Radix-Os Draconis-Ostreae Concha>Bupleuri Radix-Ostreae Concha>Bupleuri Radix）. The components of Bupleuri Radix were used as the indexes， and the content of methanol extract determined by HPLC was higher than that of water extract， and the components of Bupleuri Radix single decoction were mainly saikosaponin a （SSa） and saikosaponin c （SSc）， which were slightly higher after co-decoction compatibility. UPLC-Q-TOF-MS could identify 37 compounds in both single decoction and co-decoction. ConclusionThe combination of Bupleuri Radix， Os Draconis， and Ostreae Concha can form a smaller， more uniform， and stable nano-sized supramolecular system， which is conducive to the dissolution of the main components of Bupleuri Radix， and the Os Draconis contributes the most in this process.

Objective: To evaluate the effectiveness and safety of modified Xiaoyao powder for postpartum depression (PPD) by conducting a systematic review of randomized controlled trials (RCTs). Methods: The Chinese National Knowledge Infrastructure Databases (CNKI), the Chinese Scientific Journals Database (VIP), Wanfang, Google Scholar, the SinoMed, Embase, Cochrane Library, and PubMed databases were searched from their inception to April 25, 2023. The Cochrane Risk of Bias tool was used to assess the quality of the trials. We applied the risk ratio to present dichotomous data and the mean difference to present continuous data. Data with similar characteristics were pooled for meta-analysis and heterogeneity was assessed using I2. Results: This review included 35 trials involving 2848 participants. The quality of the included studies was low (unclear randomization processes and insufficient reporting of blinding). Participants treated with modified Xiaoyao powder plus Western medicine showed lower Hamilton Depression Scale (HAMD) depression score than those who used Western medicine alone (mean difference = −2.15; 95% confidence interval:−2.52 to 1.78; P < .00001), and higher effective rate (relative risk = 1.19; 95% confidence interval: 1.15 to 1.24; P < .00001), When comparing modified Xiaoyao alone with Western medicine, the HAMD depression score remained low, however, the efficacy rate was higher in the modified Xiaoyao group. Regarding adverse events, the modified Xiaoyao group reported weight gain, nausea, and diarrhea, but no severe adverse events were reported. Conclusion Modified Xiaoyao may help relieve depression in PPD when used alone or in combination with Western medicine, with minor side effects. Therefore, future high-quality, large-sample size RCTs are warranted.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective To investigate the impact of hemoglobin(Hb)level on the risk of all-cause mortality in elderly patients with stable coronary artery disease(SCAD)treated by percutaneous coronary intervention(PCI).Methods A retrospective cohort study was conducted on 195 elderly SCAD patients treated by PCI in our hospital from June 2016 to December 2017,a total of 180 case were followed up.They were divided into four groups based on quartiles of Hb levels:Q1 group[≤122(108.28±12.53)g/L,n=47],Q2 group[122＜Hb≤137(130.07±4.33)g/L,n=43],Q3 group[137＜Hb≤148(142.67±3.10)g/L,n=46],and Q4 group[＞148(158.36±8.50)g/L,n=44].Their clinical data were collected and compared among the groups.All patients were followed up,with all-cause mortality as endpoint.Cox regression analysis was used to evaluate the impact of Hb level on all-cause mortality in elderly SCAD patients treated by PCI.Results For the 180 patients with complete follow-up,the median follow-up time was 703(415,1121)d,and the incidence of all-cause mortality was 10.00％(totally 18 deaths).And the incidence was 25.50％(12 deaths),7.00％(3 death),4.30％(2 deaths)and 2.30％(1 death)in Q1,Q2,Q3,and Q4 groups,respectively,with statistically significant differences(P＜0.01).Univariate Cox regression analysis showed age was a risk factor for all-cause death(P＜0.01),while Hb level,BMI,smoking history,dyslipidemia,and aspirin use were a risk facotr for all-cause death(P＜0.05,P＜0.01).Further multivariate Cox regression analysis revealed Hb level was a risk facotr for all-cause death(HR=0.96,95％CI:0.93-0.99,P＜0.01).The risk of all-cause mortality was 3.68 times higher in the Q1 group than the Q2 group(HR=3.68,95％CI:1.01-13.45,P＜0.05),and there was no correlation in the incidence between the Q3 and Q4 groups(P＞0.05).Conclusion Low Hb level is an independent predictor for all-cause mortality in elderly SCAD pa-tients after PCI.

Objective:To explore the effectiveness and safety of laparoscopic-assisted liposuction in the treatment of gynecomastia.Methods:A retrospective study was conducted on 115 male breast development patients from January 2021 to May 2023 at the First Affiliated Hospital of Henan University and Shaoguan Hospital of Southern Medical University. The patients were divided into two groups based on surgical methods: the laparoscopic combined liposuction technique group (observation group) and the traditional areola incision group (control group). The control group consisted of 59 cases, aged between 18 and 52 years (26.2±5.2); There were 56 cases in the observation group, aged between 18 and 55 years (26.5±5.2). The differences in surgical time, intraoperative blood loss, drainage tube removal time, incidence of surgical complications, postoperative drainage volume, pain visual analog scale (VAS), and patient satisfaction were compared between two groups of patients.Results:The intraoperative bleeding volume, drainage tube removal time, and postoperative drainage volume in the observation group were 12.25±2.23, 2.85±0.53, and 80.52±7.53, respectively, all of which were lower than those in the control group (26.53±2.35, 4.22±0.59, 81.25±8.54, respectively), and the differences were statistically significant (all P<0.05).The incidence of sensory abnormalities in the nipple areola area of the observation group was 1.8% (1/56), which was lower than the 10.2% (6/59) of the control group, and the difference was statistically significant ( P<0.05).The postoperative breast shape, nipple shape, and incision score of the observation group were 81.15±18.52, 77.85±22.15, and 72.58±10.56 points, respectively, all higher than the control group's 69.34±18.48, 78.12±21.75, and 60.35±9.35 points, and the differences were statistically significant (all P<0.05). Conclusions:Laparoscopic combined with liposuction technology for the treatment of gynecomastia can reduce intraoperative bleeding and postoperative drainage volume and shorten the time for removing drainage tubes with better safety.
