Objective To establish an individualized nomogram model and evaluate its efficacy to provide a possible evaluation basis for the prognosis of lower third and abdominal part of oesophageal adenocarcinoma (EAC). Methods Lower third and abdominal part of EAC patients from 2010 to 2015 were chosen from the SEER Research Plus Database (17 Regs, 2022nov sub). The patients were randomly allocated to the training cohort and the internal validation cohort with a ratio of 7∶3 using bootstrap resampling. The Cox proportional hazards regression analysis was used to determine significant contributors to overall survival (OS) in EAC patients, which would be elected to construct the nomogram prediction model. C-index, calibration curve and receiver operating characteristic (ROC) curve were performed to evaluate its efficacy. Finally, the efficacy to evaluate the OS of EAC patients was compared between the nomogram prediction model and TNM staging system. Results In total, 3945 patients with lower third and abdominal part of EAC were enrolled, including 3475 males and 470 females with a median age of 65 (57-72) years. The 2761 patients were allocated to the training cohort and the remaining 1184 patients to the internal validation cohort. In the training and the internal validation cohorts, the C-index of the nomogram model was 0.705 and 0.713, respectively. Meanwhile, the calibration curve also suggested that the nomogram model had a strong capability of predicting 1-, 3-, and 5-year OS rates of EAC patients. The nomogram also had a higher efficacy than the TNM staging system in predicting 1-, 3-, and 5-year OS rates of EAC patients. Conclusion This nomogram prediction model has a high efficiency for predicting OS in the patients with lower third and abdominal part of EAC, which is higher than that of the current TNM staging system.

ObjectiveTo explore the mechanism of herbal cake-separated moxibustion using the classical formula Xiaoyaosan in alleviating neuroimmune inflammatory responses in chronic fatigue syndrome (CFS) rats, based on the regulation of the toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear transcription factor-κB (NF-κB) signaling pathway. MethodsFifty SPF-grade SD rats aged 6-8 weeks were randomly divided into five groups: Normal group, model group, sham herbal cake moxibustion group, Chinese medicine intragastric administration group, and herbal cake-separated moxibustion group, with 10 rats in each group. Except for the normal group, all other groups underwent a 21-day modeling process, followed by behavioral testing. The herbal cake-separated moxibustion and sham herbal cake moxibustion groups received interventions at the Shenque (CV8), Guanyuan (CV4), Zusanli (ST36), and Qimen (LR14) acupoints. The Chinese medicine intragastric administration group was treated with a Xiaoyaosan suspension via gavage. Behavioral tests were conducted after 10 days of continuous intervention. Serum levels of interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF-α), as well as hippocampal levels of IL-1β, IL-6, TNF-α, and NF-κB, were detected by enzyme-linked immunosorbent assay (ELISA). Morphological changes in the hippocampus were observed using hematoxylin-eosin (HE) staining. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression levels of TLR4, MyD88, and NF-κB in the hippocampus. Western blot analysis was performed to detect the relative expression levels of TLR4, MyD88, NF-κB, and p65 proteins in the hippocampus. ResultsCompared with the normal group, the model group showed a significant decrease in upright times during the open field test (P<0.01), as well as significant reductions in total movement distance, resting time, and center region duration (P<0.01). In the tail suspension test, immobility time increased (P<0.01), and struggle times decreased (P<0.01). Serum and hippocampal levels of IL-1β, IL-6, and TNF-α, as well as hippocampal NF-κB levels and TLR4, MyD88, and NF-κB mRNA expression, were significantly elevated (P<0.01). After treatment, compared with the model group, the total movement distance and upright times in the open field test were significantly increased in all treatment groups (P<0.01), while resting time and center region duration were notably prolonged (P<0.05, P<0.01). Immobility time in the tail suspension test was significantly shortened (P<0.01), and struggle times significantly increased (P<0.05). Serum and hippocampal levels of IL-1β, IL-6, TNF-α, hippocampal NF-κB levels, and TLR4 and NF-κB mRNA expression were significantly reduced (P<0.05, P<0.01). Compared with the sham herbal cake moxibustion group, the herbal cake-separated moxibustion group showed a significant extension in center region duration during the open field test (P<0.05) and a significant increase in upright times (P<0.01). In the tail suspension test, immobility time was reduced (P<0.01), and struggle times increased (P<0.01). Serum TNF-α levels in the Chinese medicine intragastric administration group were significantly reduced (P<0.01), while serum IL-6 levels, as well as hippocampal levels of IL-1β, TNF-α, NF-κB, and TLR4, MyD88, and NF-κB mRNA expression, were significantly decreased in both the Chinese medicine intragastric administration group and the herbal cake-separated moxibustion group (P<0.05, P<0.01). Compared with the Chinese medicine intragastric administration group, the herbal cake-separated moxibustion group exhibited significantly increased upright times in the open field test (P<0.01). In the tail suspension test, immobility time was reduced (P<0.01), and struggle times increased (P<0.01). Serum IL-1β, hippocampal TNF-α levels, and TLR4, MyD88, and NF-κB mRNA expression were significantly decreased (P<0.05, P<0.01). ConclusionHerbal cake-separated moxibustion effectively improves fatigue and memory function in CFS rats, regulates neuroimmune inflammatory responses, and its mechanism may be related to the modulation of the TLR4/MyD88/NF-κB signaling pathway.

BACKGROUND:Immunosuppression leads to impaired body immune function and aggravates the disease.Herb-partitioned moxibustion can effectively regulate immune function and improve immunity in the body,but its regulatory mechanism has not been elucidated. OBJECTIVE:To sequence immunosuppressed model rats treated with herb-partitioned moxibustion using bioinformatics techniques based on transcriptomics and to explore the mechanisms by which it regulates immunity. METHODS:Twenty-four Sprague-Dawley rats were randomly assigned to three groups:control,model,and herb-partitioned moxibustion groups,with eight rats in each group.The model and herb-partitioned moxibustion groups were subjected to establishment of an immune suppression model by intraperitoneal injection of cyclophosphamide at a dose of 35 mg/kg for 3 consecutive days.No interventions were administered to the control and model groups after modeling.In contrast,the herb-partitioned moxibustion group received moxibustion treatment at Zhongwan,Shenque,Guanyuan,and Zusanli acupoints using a combination of moxa and herbal cakes,once a day,for 10 consecutive days,with samples being collected the day after the end of the intervention.Peripheral blood was collected from all groups of rats to measure their white blood cell count.RNA-seq was performed on the Illumina sequencing platform,and differentially expressed genes were selected for bioinformatics analysis using the GO and KEGG databases. RESULTS AND CONCLUSION:Compared with the control group,the model group exhibited a significant decrease in white blood cell count(P<0.001).RNA-seq analysis identified 3 026 differentially expressed genes between the model and control groups,with 1 565 upregulated and 1 461 downregulated.There were 535 differentially expressed genes identified between the herb-partitioned moxibustion group and the model group,with 280 upregulated and 255 downregulated.The Venn diagram analysis revealed that 159 genes were downregulated in the model group compared with the control group.However,after moxibustion with herbal cakes,these genes were upregulated.Protein-protein interaction network analysis identified 10 core targets,including Oasl,Oas2,Isg15,Herc6,Mx2,Helz2,Mx1,Syk,Hspa1a,and Ret.According to GO and KEGG analyses,moxibustion with herbal cakes regulated the body through pathways related to immune response,viruses,angiogenesis,and the autoimmune system.To conclude,there is a significant association between herbal cake-separated moxibustion intervention and immune suppression targets,including Oasl,Oas2,Isg15,Herc6,Mx2,Helz2,and Mx1.The intervention exhibits regulatory effects in the pathways related to immune responses,viral activities,and angiogenesis.

ObjectiveTo explore the effects of the Tai Chi training on bone density, bone turnover markers, and heart rate variability for people with high-risk osteoporosis, and to provide evidence for the prevention of osteoporosis at early stage. MethodsSixty-six cases of people with high risk of osteoporosis were included, and they were divided into 33 cases each in the intervention group and the control group using the random number table method. The control group received osteoporosis health education three times a week, and the intervention group received Tai Chi training under the guidance of a trainer three times a week for 40 mins each time on the basis of the control group, and both groups were intervened for 12 weeks. Dual-energy X-ray absorptiometry was used to measure the bone density of L1~L4 vertebrae, bilateral femoral necks and bilateral total hips in the two groups before and after the intervention; enzyme-linked immunosorbent assay was used to determine bone turnover markers before and after the intervention, including pro-collagen type Ⅰ pro-amino-terminal prepropyl peptide (P1NP) and β-collagen type Ⅰ cross-linking carboxy-terminal peptide (β-CTX). Seven cases with good compliance in the intervention group were selected. After wearing the heart rate sensor, they successively performed Tai Chi training and walking activities recommended by the guideline for 20 mins each, and the heart rate variability (HRV) during exercise was collected, including time-domain indexes such as standard deviation of normal sinus intervals (SDNN), root-mean-square of the difference between adjacent RR intervals (RMSSD), frequency-domain metrics such as low-frequency power (LF), high-frequency power (HF), and low-frequency/high-frequency power ratio (LF/HF), as well as nonlinear metrics such as approximate entropy (ApEn), sample entropy (SampEn). ResultsFinally, 63 cases were included in the outcome analysis, including 30 cases in the intervention group and 33 cases in the control group. After the intervention, the differences of L1~L4 vertebrae, bone density of bilateral femoral neck and bilateral total hip in the intervention group were not statistically significant when compared with those before intervention (P>0.05), while the bone density of all parts of the control group decreased significantly compared with that before intervention (P<0.05), and the difference in the bone density of the L1~L4 vertebrae, bilateral femoral neck, and the right total hip before and after the intervention of the intervention group was smaller than that of the control group (P<0.05). The differences in P1NP and β-CTX between groups before and after intervention was not statistically significant (P>0.05). Compared with walking exercise, LF decreased, HF increased and LF/HF decreased during Tai Chi exercise (P<0.05); the time domain indexes and non-linear indexes between groups had no statistically significant difference (P>0.05). ConclusionTai Chi exercise can maintain lumbar, hip, and femoral bone density and improve sympathetic/parasympathetic balance in people at high risk for osteoporosis, but cannot significantly improve bone turnover markers.

Objective To evaluate the efficacy and safety of biomaterial sling in the treatment of female stress urinary incontinence (SUI), so as to explore the possibility of replacing traditional synthetic materials with biomaterials in SUI surgery. Methods Clinical data of 22 SUI patients undergoing retropubic mid-urethral sling surgery in our hospital during Jan.and Dec.2023 were retrospectively collected. Perioperative parameters were analyzed, and all patients were followed up for more than one year. The quality of life was assessed using the incontinence impact questionnaire-short form-7 (IIQSF-7), numerical rating scale (NRS), and urogenital distress inventory-short form-6 (UDI-6). Results All 22 operations were successfully completed. The follow-up was 13-25 (mean 15.2±4.6) months, operation time (47.0±11.1) minutes, hospital stay (0.8± 0.2) days, and pain duration (6.1±4.9) days. One year after surgery, all patients'NRS, IIQSF-7 and UDI-6 scores were significantly reduced (P<0.001). One week after surgery, all patients were improved. No sling exposure or urinary tract infection was found during the follow-up. Conclusion Biomaterial sling is an effective and relatively safe method for the treatment of female SUI, demonstrating satisfactory short-term outcomes. However, the long-term effects still need further research.

ObjectiveTo investigate the differences in clinical efficacy of different medication regimens of Wangbi Tablets (尪痹片) for knee osteoarthritis (KOA) in a real-world setting, providing a basis for rational clinical use of Wangbi Tablets. MethodsA prospective registry study was conducted, involving 2,999 KOA patients registered in 30 hospitals nationwide from January 26th, 2019, to December 17th, 2021. Based on the use of Wangbi Tablets during the observation period, patients were divided into a monotherapy group (1,507 cases) and a combination therapy group (1,492 cases), and the combination group can be further divided into Wangbi Tablets plus Chinese medicine (CM), Wangbi Tablets plus western medicine (WM), and Wangbi Tablets plus Chinese and western medicine (CM+WM) subgroups. The baseline data of patients in the monotherapy group and the combination group were compared, including age, gender, body weight, medication time, clinical stage, K-L grade, and others. Efficacy indicators included the Visual Analog Scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and EuroQol five-dimensional (EQ-5D) health index, which were evaluated before and after 4-, 8- and 12-week treatment, and the difference before and after treatment was calculated after 4, 8 and 12 weeks of treatment. The difference between the baseline and 12 weeks of treatment of all the above indicators was used as the dependent variables, and gender, age, body mass index (BMI), course of disease, K-L grade, and clinical stage were used as independent variables, when multiple linear regression was taken to explore the influencing factors of the efficacy. At the same time, the occurrence of major symptoms (including morning stiffness, joint swelling, soreness of waist and knees, fear of wind, and fear of cold) was counted, and the disappearance of symptoms at each time point was counted after 4, 8, and 12 weeks of treatment. ResultsAt baseline, there were no statistically significant differences in gender and age distribution between the monotherapy and combination therapy groups (P>0.05); the proportion of patients in the acute stage and recovery stage was higher in the monotherapy group than in the combination therapy group, while the proportion in the remission stage was lower (P<0.05); the VAS score was higher in the monotherapy group, and the EQ-5D index was lower (P<0.01), with no statistically significant difference in total WOMAC score between the two groups (P>0.05). Compared to those measured before treatment and at previous timepoint, the VAS score and WOMAC total score significantly decreased in both groups, while EQ-5D value increased (P<0.05). The difference in VAS score between baseline and after 12-week treatment was higher in the monotherapy group than the combination group, while the differences in WOMAC total score and EQ-5D value between baseline and after 4-, 8- and 12-week treatment were higher in the combination group (P<0.05). Multiple linear regression showed that VAS score before treatment had greatest impact on pain improvement (P<0.01), and compared to Wangbi Tablets monotherapy, the combination of Wangbi tablets with WM or CM had larger associations with pain improvement (P<0.05); and Wangbi Tablets had better efficacy when the course of treatment was >28 days (P<0.01). Wangbi Tablets plus WM had a better effect on improving the overall function of the knee joint than Wangbi Tablets alone (P<0.01); and the efficacy of Wangbi Tablets with a course of treatment >28 days was better (P<0.05). The improvement of quality of life of patients in the attack and remission stages was more obvious than that in the recovery stage (P<0.01); Wangbi Tablets plus WM or CM had a better effect on improving quality of life than Wangbi Tablets alone (P<0.05). Before treatment, the proportion of patients with morning stiffness, soreness of waist and knees, fear of wind and chills in the monotherapy group was higher than that in the combination group (P<0.01). The proportion of main symptoms in both groups decreased after 4, 8 and 12 weeks of treatment (P<0.05). After 4 weeks of treatment, the disappearance rate of each main symptom in the combination group was higher than that in the monotherapy group, and after 12 weeks of treatment, the disappearance rate of fear of wind in the monotherapy group was higher than that in the combination group, while the disappearance rate of joint swelling and soreness of waist and knees was lower (P<0.05). ConclusionWangbi Tablets, whether used alone or in combination with other medications, is effective throughout the course of KOA, with greater benefits in improving joint function and quality of life during the acute and remission stages compared to the recovery stage. Combination therapy had a faster onset of effect, but began to converge with monotherapy after 8 weeks. The best efficacy was observed with the combination of Wangbi Tablets with WM, followed by combination with CM.

Objective:To investigate the effect of bone mesenchymal stem cells derived exosomes (BMSC-Exo) on improving hippocampal microangiogenesis, energy metabolism, and behaviors in depression mouse models.Methods:(1) Mouse bone marrow mesenchymal stem cells were isolated and cultured to extract BMSC-Exo; BMSC-Exo morphology was observed by transmission electron microscopy, BMSC-Exo particle diameter ranges were determined by Zetaview analyzer, and expressions of CD9 and CD63 in BMSC-Exo were detected by Western blotting. (2) Depression models were established in 2 mice by chronic unforeseeable mild stress (CUMS); 24 h after stereotaxic injection of phosphate buffer solution (PBS) or DiR labeled BMSC-Exo, BMSC-Exo uptake was detected by in vivo imaging system. (3) Thirty-six mice were randomly divided into control group, model group and BMSC-Exo group ( n=12); CUMS was used to establish depression models in the latter 2 groups; brain stereotaxic injection of 1 μL BMSC-Exo was given to mice in the BMSC-Exo group after modeling, and same amount of PBS was given to the control group; behaviors were observed by forced swimming test (FST), tail suspension test (TST) and open field test (OFT); hippocampal microvascular length and number were detected by alkaline phosphatase staining; energy metabolism in the hippocampus was detected by micro positron emission tomography/computed tomography (mPET/CT); glucose transporter 1 (GLUT1) expression in the hippocampus was detected by Western blotting. Results:(1) BMSC-Exo had a typical disk-like vesicle-like structure with particle size of (100.5±1.4) nm; Western blotting confirmed that CD9 and CD63 expressed in BMSC-Exo. (2) In vivo imaging showed no fluorescence in the brain and liver after PBS injection, but obvious local fluorescence after BMSC-Exo injection. (3) Compared with the control group, the model group and BMSC-Exo group had significantly longer rest time in FST and TST and shorter movement distance and time in the central region of OFT ( P<0.05); compared with the model group, BMSC-Exo group had significantly shorter rest time in FST and TST and longer movement distance and time in the central region of OFT ( P<0.05). Compared with the control group, the model group and BMSC-Exo group had significantly decreased standard uptake value (SUV) of regions of interest, microvascular length and number, and GLUT1 expression in the hippocampus ( P<0.05); compared with the model group, the BMSC-Exo group had significantly higher SUV, microvascular length and number, and GLUT1 expression in the hippocampus ( P<0.05). Positive correlations were noted between hippocampal microvascular length and SUV and between microvascular number and SUV in the 3 groups ( r=0.540, P<0.001; r=0.600, P<0.001). Conclusion:BMSC-Exo could promote microangiogenesis energy metabolism in the hippocampus to improve depression-like behaviors in depression mouse models.

ObjectiveRoot rot is one of the most serious diseases in the cultivation and production of Atractylodes lancea. Trichoderma spp. are effective in the biocontrol of root rot without causing environmental pollution. This study aims to isolate and study a Trichoderma strain capable preventing and controlling root rot from the rhizosphere of A. lancea and to solve the problem of disease prevention and control in the planting and production of A. lancea. MethodTrichoderma T2204 was isolated by the dilution-coating method and identified by ITS sequencing. The inhibitory activities of T2204 and its volatiles against two pathogenic fungal strains were examined by dual-culture and co-culture experiments. The biocontrol potential of T2204 on root rot of A. lancea and the effect of T2204 on the accumulation of medicinal compounds in the rhizosphere of A. lancea were investigated by pot experiments and GC-MS, respectively. In addition, the optimal medium, photoperiod, temperature, pH, and carbon and nitrogen sources for the culture of T2204 were explored. ResultThe Trichoderma isolate T2204 was identified as T. citrinoviride and had direct inhibitory effects on two highly pathogenic strains causing root rot. In the dual-culture experiments with the two pathogenic strains, T2204 showcased the inhibition rates of 77.90% and 76.80%, respectively. In the co-culture experiments with the two pathogenic strains, the volatile organic compounds produced by T2204 showed the inhibition rates of 57.11% and 81.11%, respectively. The pot experiments showed that the survival rate of A. lancea seedlings infected by root rot reached 100% after inoculation with T2204 and was only 50% in the case without inoculation of T2204. After 150 days of cultivation, the dry weight and atractylodin content of the rhizome of A. lancea plants treated with T2204 increased by 32% (P<0.05) and 11%, respectively, compared with the untreated group. The optimal conditions for the growth of T2204 were PDA or PSA medium, photoperiod of 12 h dark/12 h light, 25-30 °C, pH 5-6, carbon sources of glucose, D-fructose, soluble starch, and maltose, and the nitrogen sources of ammonium sulfate and ammonium dihydrogen phosphate. The optimal conditions for the sporulation of T2204 were PSA or CMA medium, photoperiod of 12 h dark/12 h light, 20-30 °C, pH 8, carbon source of sucrose, and nitrogen source of sodium nitrate. ConclusionT2204 could improve the growth and root rot resistance of A. lancea and promote the accumulation of medicinal compounds. The findings laid a foundation for the industrialized production and application of T2204 in the production of A. lancea in the future.

Objective:To investigate the predictive value of infiltrating zone contrast-enhanced ultrasound(CEUS) gradient features in Nottingham grading and pathologically true infiltration of invasive ductal carcinoma(IDC).Methods:A retrospective analysis was performed on 78 female breast cancer patients (95 masses) confirmed by surgical and pathology in the Affiliated Hospital of Jiangsu University from July 2019 to June 2022, which were divided into Grade-Ⅰ (22 masses), Grade-Ⅱ (28 masses), and Grade-Ⅲ (45 masses) according to the Nottingham histological grading system. The differences in the maximum diameter of the infiltration zone and the characteristic parameters of the gradient of the inner and outer edges of the infiltration zone among the three groups of masses were compared, and the differential gradient features among them were analyzed by multivariate ordered Logistic regression and ROC curves. The relationship between the differential gradient characteristics of the infiltration zone and the pathologically true infiltration of the mass was further explored.Results:The univariate analysis showed statistically significant differences among the three groups for peak-arrival time gradient (ΔTTP), ascending branch slope gradient (ΔRS), peak intensity gradient (ΔPI) and area gradient under the curve (ΔAUC) (all P<0.05). Multiple ordered logistic regression analysis showed that ΔTTP, ΔPI and ΔAUC had independent influences on the histologic grading of IDC (all P<0.05), and the area under the curve for the combination of the three in predicting IDC histology grades Ⅰ, Ⅱ and Ⅲ was 0.692, 0.705 and 0.765, respectively. In addition, the maximum diameter of pathologically true infiltration of the mass was positively correlated with ΔTTP ( r=0.621, P<0.05) and negatively correlated with ΔPI ( r=-0.605, P<0.05) and ΔAUC ( r=-0.719, P<0.05). Conclusions:Infiltration zone CEUS gradient features are effective in predicting the histologic grade of IDC and strongly correlate with the degree of pathologically true infiltration of the mass.
