The density and composition of lymphocytes infiltrating colon tumors serve as predictive factors for the clinical outcome of colon cancer.Our previous studies highlighted the potent anti-cancer properties of the principal compounds found in Garcinia yunnanensis(YTE-17),attributing these effects to the regu-lation of multiple signaling pathways.However,knowledge regarding the mechanism and effect of YTE-17 in the prevention of colorectal cancer is limited.In this study,we conducted isobaric tags for relative and absolute quantification(iTRAQ)analysis on intestinal epithelial cells(IECs)exposed YTE-17,both in vitro and in vivo,revealing a significant inhibition of the Wnt family member 5a(Wnt5a)/c-Jun N-terminal kinase(JNK)signaling pathway.Subsequently,we elucidated the influence and mechanism of YTE-17 on the tumor microenvironment(TME),specifically focusing on macrophage-mediated T helper 17(Th17)cell induction in a colitis-associated cancer(CAC)model with Wnt5a deletion.Additionally,we performed the single-cell RNA sequencing(scRNA-seq)on the colonic tissue from the Wnt5a-deleted CAC model to characterize the composition,lineage,and functional status of immune mesenchymal cells during different stages of colorectal cancer(CRC)progression.Remarkably,our findings demon-strate a significant reduction in M2 macrophage polarization and Th17 cell phenotype upon treatment with YTE-17,leading to the restoration of regulatory T(Treg)/Th17 cell balance in azoxymethane(AOM)/dextran sodium sulfate(DSS)model.Furthermore,we also confirmed that YTE-17 effectively inhibited the glycolysis of Th17 cells in both direct and indirect co-culture systems with M2 macrophages.Notably,our study shed light on potential mechanisms linking the non-canonical Wnt5a/JNK signaling pathway and well-established canonical β-catenin oncogenic pathway in vivo.Specifically,we proposed that Wnt5a/JNK signaling activity in IECs promotes the development of cancer stem cells with β-catenin activity within the TME,involving macrophages and T cells.In summary,our study undergoes the po-tential of YTE-17 as a preventive strategy against CRC development by addressing the imbalance with the immune microenvironment,thereby mitigating the risk of malignancies.

Objective:To investigate the role of dopamine receptors in the central amygdala (CeA) in reduction of the anxiety level by propofol in a mouse model of post-traumatic stress disorder (PTSD).Methods:Fifty-six SPF healthy adult male C57BL/6 mice, aged 10 weeks, weighing 20-25 g, were divided into 7 groups ( n=8 each) using a random number table method: control group (C group), PTSD group (P group), PTSD+ propofol group (PP group), PTSD+ fat emulsion group (PF group), PTSD+ propofol+ normal saline group (PPN group), PTSD+ propofol+ dopamine receptor D1 (DRD1) antagonist group (PP+ DRD1-Ant group), and PTSD+ propofol+ DRD2 antagonist group (PP+ DRD2-Ant group). The PTSD model was developed by continuous plantar electric shock for 3 days. Propofol 120 mg/kg was intraperitoneally injected after successful establishment of the model in PP group, and the equal volume of fat emulsion was intraperitoneally injected in PF group. In PPN group, PP+ DRD1-Ant group and PP+ DRD2-Ant group, the equal volume of normal saline, DRD1 antagonist hydrochloride and DRD2 antagonist eticlopride hydrochloride were injected in bilateral CeA regions, respectively, 30 min later the efficacy of drugs reached the peak, and then propofol 120 mg/kg was intraperitoneally injected. The anxiety levels were measured at 4 h (T 1) and day 3 after propofol injection (T 2) by the open field test and elevated cross maze test. Results:Compared with C group, the time spent entering the open and central areas was significantly shortened at T 1, 2, and the number of entering the open and central areas was decreased at T 1, 2 in P group ( P<0.001). Compared with P group, the time spent entering the open and central areas was significantly prolonged at T 1, the number of entering the open and central areas was increased at T 1 ( P<0.001), and no significant change was found at T 2 in PP group ( P>0.05), and no significant change was found in the aforementioned parameters at T 1, 2 in PF group ( P>0.05). Compared with PPN group, the time spent entering the open and central areas was significantly shortened at T 1, and the number of entering the open and central areas was decreased at T 1 in PP+ DRD2-Ant group ( P<0.001), and no significant change was found at T 1 in PP+ DRD1-Ant group ( P>0.05). Conclusions:Activation of DRD2 in the CeA is involved in the process by which propofol reduces the anxiety level of mice with PTSD.

Objective:To explore the risk factors of acute kidney injury(stage 3)developed within 48 hours in elderly patients with sepsis, and to use them to develop a risk prediction model and then evaluate and externally validate the model.Methods:Clinical data of all elderly patients(age≥ 60 years)with sepsis in the intensive care medicine information database(MIMIC-Ⅳ v1.0)were extracted.Independent risk factors were determined by multivariate logistic regression analysis.A risk prediction model was constructed, a nomogram was drawn, and the receiver operating characteristic curve(ROC)and the Hosmer-Lemeshow(H-L)test were used to evaluate the model's prediction accuracy and R-squared.Clinical data of elderly patients(age≥ 60 years)with sepsis admitted to the Department of Critical Care Medicine of the Second People's Hospital of Hefei from May 2019 to October 2021 were retrospectively collected and fed into the prediction model to conduct external validation.Results:A total of 1 977 elderly patients with sepsis were screened out from the MIMIC-IV database and included in the training set, of whom, 544 developed AKI-stage 3 within 48 hours.Univariate analysis was performed for factors that might be associated with acute kidney injury in elderly patients with sepsis.Compared with the normal group that did not progress to AKI stage 3, there were statistically significant differences in 28 indicators, such as the duration of ICU stay, intravenous fluid intake in 24 hours, and use of vasoactive drugs[5(3, 9)d vs.7(4, 12)d; 2.05(1.17, 3.27)ml·kg -1·h -1vs.2.37(1.47, 4.10)ml·kg -1·h -1; 761(53.11%) vs.375(68.93%), P<0.001]. Based on the results of multivariate logistic regression analysis, a prediction model was finally constructed with 9 variables: albumin( OR=0.983, 95% CI: 0.966-0.999, P=0.040), aspartate transaminase( OR=1.000, 95% CI: 1.000-1.000, P<0.001), APTT( OR=1.005, 95% CI: 1.001-1.009, P=0.028), total bilirubin( OR=1.003, 95% CI: 1.001-1.004, P=0.001), serum creatinine( OR=1.005, 95% CI: 1.004~1.007, P<0.001), Charlson score( OR=1.117, 95% CI: 1.061-1.177, P<0.001), intravenous fluid intake in 24 hours( OR=1.101, 95% CI: 1.034-1.173, P=0.003), weight( OR=1.023, 95% CI: 1.018-1.029, P<0.001), and mechanical ventilation( OR=2.412, 95% CI: 1.843-3.157, P<0.001). Then a nomogram was generated.The area under the ROC curve(AUC)of the prediction model was 0.755(95% CI: 0.731-0.780), and the H-L test was conducted( χ2=10.89, P=0.208>0.05), indicating a good fit.Data from 102 elderly patients were included in the validation set, with 27 cases that had developed AKI-stage3 within 48 hours, and were fed into the prediction model, with an AUC of 0.778(95% CI: 0.676-0.880)and χ2=3.72 and P=0.882>0.05 from the H-L test, consistent with the results of the training set. Conclusions:The model has some predictive value for acute kidney injury in elderly patients with sepsis.

Objective: This study aimed to determine the efficacy of dose-enhanced immunochemotherapy followed by autologous peripheral blood stem cell transplantation (ASCT) in young patients with newly diagnosed high-risk aggressive B-cell lymphoma. Methods: A retrospective study was conducted to examine the clinical and survival data of young patients with high-risk aggressive B-cell lymphoma who received dose-enhanced immunochemotherapy and ASCT as first-line treatment between January 2011 and December 2018 in Blood Diseases Hospital. Results: A total of 63 patients were included in the study. The median age range was 40 (14-63) years old. In terms of the induction therapy regimen, 52 cases received R-DA-EP (D) OCH, and the remaining 11 received R-HyperCVAD/R-MA. Sixteen (25.4% ) patients achieved partial response in the mid-term efficacy assessment, and ten of them were evaluated as complete response after transplantation. The median follow-up was 50 (8-112) months, and the 3-year progression-free survival (PFS) rate and overall survival (OS) rate were (83.9±4.7) % and (90.4±3.7) % , respectively. Univariate analysis demonstrated that age-adjusted international prognostic index ≥2 scores was a negative prognostic factor for OS (P=0.039) , and bone marrow involvement (BMI) was an adverse prognostic factor for OS (P<0.001) and PFS (P=0.001) . However, multivariate analysis confirmed that BMI was the only independent negative predictor of OS (P=0.016) and PFS (P=0.001) . Conclusions: The use of dose-enhanced immunochemotherapy in combination with ASCT as first-line therapy in the treatment of young, high-risk aggressive B-cell lymphoma results in good long-term outcomes, and BMI remains an adverse prognostic factor.

Traditional Chinese Medicine (TCM) has certain advantages in the treatment of precancerous lesions of gastric cancer (PLGC) based on the holistic concept and the thought of syndrome differentiation. Currently, it is generally divided into 6 kinds of syndromes: liver and stomach qi stagnation syndrome, liver and stomach heat stagnation syndrome, spleen and stomach weakness syndrome (including spleen and stomach qi deficiency syndrome with coldness), spleen and stomach damp heat syndrome, stomach yin deficiency syndrome and blood stasis in stomach collateral syndrome. Clinically, the doctor should treat PLGC patients according to different syndrome types by using Chinese medicine prescription, which could improve the gastric mucosal pathological state, gastroscopy and clinical symptoms, to rehibit the development of precancerous lesions, reduce the incidence rate of gastric cancer. In the future, the doctors shouldreach the consensus of treating PLGC with TCM diagnosis, and focus on the research of TCM compounds or monomers with obvious curative effect, increase the times of follow-up, and evaluate the long-term curative effect.

PURPOSE:
The combined use of antibiotics and anti-inflammatory medicine to manage bacterial endotoxin-induced inflammation following injuries or diseases is increasing. The cytokine level produced by macrophages plays an important role in this treatment course. Ciprofloxacin and indomethacin, two typical representatives of antibiotics and anti-inflammatory medicine, are cost-effective and has been reported to show satisfactory effect. The current study aims to investigate the effect of ciprofloxacin along with indomethacin on the secretion of inflammatory cytokines by macrophages in vitro.
METHODS:
Primary murine peritoneal macrophages and RAW 264.7 cells were administrated with lipopolysaccharide (LPS) for 24 h. The related optimal dose and time point of ciprofloxacin or indomethacin in response to macrophage inflammatory response inflammation were determined via macrophage secretion induced by LPS. Then, the effects of ciprofloxacin and indomethacin on the secretory functions and viability of various macrophages were determined by enzyme-linked immunosorbent assay and flow cytometry analysis, especially for the levels of interleukin (IL)-1β, IL-6, IL-10, and tumor necrosis factor (TNF)-α. The optimal dose and time course of ciprofloxacin affecting macrophage inflammatory response were determined by testing the maximum inhibitory effect of the drugs on pro-inflammatory factors at each concentration or time point.
RESULTS:
According to the levels of cytokines secreted by various macrophages (1.2 × 106 cells/well) after administration of 1 μg/mL LPS, the optimal dose and usage timing for ciprofloxacin alone were 80 μg/mL and 24 h, respectively, and the optimal dose for indomethacin alone was 10 μg/mL. Compared with the LPS-stimulated group, the combination of ciprofloxacin and indomethacin reduced the levels of IL-1β (p < 0.05), IL-6 (p < 0.05), IL-10 (p < 0.01)), and TNF-α (p < 0.01). Furthermore, there was greater stability in the reduction of inflammatory factor levels in the combination group compared with those in which only ciprofloxacin or indomethacin was used.
CONCLUSION
The combination of ciprofloxacin and indomethacin suppressed the levels of inflammatory cytokines secreted by macrophages in vitro. This study illustrates the regulatory mechanism of drug combinations on innate immune cells that cause inflammatory reactions. In addition, it provides a new potential antibacterial and anti-inflammatory treatment pattern to prevent and cure various complications in the future.

Objective To discuss the main reasons for the difference of sedum development between Daur adults in Inner Mongolia and Xinjiang. Methods Nine circumference values and six skin fold thickness of 544 adults of Daur nationality (304 in Xinjiang and 240 in Inner Mongolia) were investigated by random sampling. Circumferences, skin fold thickness and obesity indexes of Daur nationality in Xinjiang and Inner Mongolia were analyzed. Results There were significant differences in 8 circumference without thigh circumference, 2 skin fold thickness such as triceps skinfold, subscapularis skinfold, 3 obesity indexes such as Verv index, body fat rate, body mass index(BMI). Correspondence analysis showed that subcutaneous fat development was stronger in northern regions than in southern regions. Conclusion The Daur nationality in Inner Mongolia has more fat and less muscle than that in Xinjiang. The problems of overweight and obesity in both regions are serious. It is suggested to pay attention to exercise and diet. Low temperature,lack of physical exercise, low temperature, low economic and medical standards and unhealthy eating habits can thicken subcutaneous fat.
