ObjectiveTo explore the effects of Yimei Baijiang formula （YMBJF） on colitis-associated colorectal cancer （CAC） and the nuclear factor kappaB （NF-κB） signaling pathway in mice. MethodsSixty male Balb/c mice of 4-6 weeks old were randomized into 6 groups： Normal， model， capecitabine （0.83 g·kg^-1）， and low-， medium-， and high-dose （4.63， 9.25， 18.50 g·kg^-1， respectively） YMBJF. The mouse model of CAC was established by combining azoxymethane （AOM， 10 mg·kg^-1） and dextran sulfate sodium （DSS， 2%）. At the 5^th week after the start of modeling， the capecitabine group and the YMBJF groups were respectively administrated with the corresponding doses of drugs by gavage once a day for a total of 6 weeks. The body weights and general conditions of mice were measured and observed， and the disease activity index （DAI） was scored. The tumors in the colorectal tissue were counted， and the colorectal length was measured. The histological features of the colorectal tissue in each group of mice were observed by hematoxylin-eosin （HE） staining. The levels of inflammatory cytokines including interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in the serum were determined by enzyme-linked immunosorbent assay （ELISA）. The expression and localization of proliferating cell nuclear antigen-67 （Ki67）， proliferating cell nuclear antigen （PCNA）， and phosphorylated nuclear transcription factor-κB p65 （p-NF-κB p65） proteins were observed by immunohistochemistry （IHC）. The apoptosis of tumor cells was observed by the TUNEL assay. The mRNA levels of IL-6，IL-1β， TNF-α， nuclear transcription factor-κB p65 （NF-κB p65）， NF-κB inhibitor alpha （IκBα）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in the colorectal tissue were quantified by Real-time polymerase chain reaction（Real-time PCR）. The protein levels of NF-κB p65， phosphorylated （p）-NF-κB p65， IκBα， p-IκBα， Bcl-2， and Bax in the colorectal tissue were determined by Western blot. ResultsCompared with the model group， each YMBJF group showed decreases in DAI and tumor number （P0.01）， and the medium-dose and high-dose YMBJF groups showed increases in colorectal length （P0.05）. In addition， each YMBJF group showed alleviated colorectal mucosal pathological injury， declined levels of IL-6， IL-1β， and TNF-α in the serum （P0.05）， reduced expression of Ki67 and PCNA （P0.01）， and down-regulated expression of p-NF-κB p65 （P0.05）. The apoptosis in the medium-dose and high-dose YMBJF groups increased （P0.01）. Each YMBJF group and the capecitabine group showed down-regulated mRNA levels of IL-1β， TNF-α， IL-6， NF-κB p65， and Bcl-2 （P0.05） and up-regulated mRNA levels of IκBα and Bax （P0.05）. The mRNA level of IκBα was up-regulated， and that of Bcl-2 was down-regulated （P0.05） in the high-dose YMBJF group. The protein levels of p-IκBα and Bcl-2 were down-regulated （P0.05） in each YMBJF group. The protein levels of IκBα and Bax were up-regulated in the medium-dose and high-dose YMBJF groups （P0.01）， while those of NF-κB p65 and p-NF-κB p65 were down-regulated （P0.05）. ConclusionYMBJF can reduce the number of tumors， reduce the levels of inflammatory factors， promote tumor cell apoptosis， and inhibit tumor cell proliferation by regulating the direct effector molecules of the NF-κB signaling pathway in the mouse model of CRC.

Chemotherapeutic drugs, such as cisplatin and phenanthriplatin (PhenPt), as STING agonists to induce DNA damage and activate the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) signaling pathway provides a potential strategy for clinical chemo-immunotherapy. However, treatment with Pt-based drugs leads to irreversible ectopia of phosphatidylserine (PS), a major component of the intracellular membrane, to the surface of the cancer cells by enzymes (Xkr8). Exposed PS can bind to immune cell receptors and inhibit the presentation of tumor antigens, leading to immunosuppression and attenuation of chemotherapy. Herein, we report a novel approach to enhance chemo-immunotherapy by constructing siRNA targeted Xkr8 (siXkr8)-mediated tetrahedral framework nucleic acid nanogel structure concurrently loaded with PhenPt (siXkr8-FNG/PhenPt) for co-delivery of siRNA and Pt-based drugs. The results showed that siXkr8-FNG/PhenPt can not only be used as an efficient delivery carrier to deliver siXkr8, block the expression of Xkr8, reduce the exposure of PS on the cancer cells surface, but also act as an immune stimulant to activate cGAS-STING pathway, effectively improve the immunosuppressive microenvironment, produce antitumor immune response, and inhibit tumor growth and metastasis. Overall, this new delivery system is important for improving the effect of Pt-based drug chemotherapy, inducing immune enhancement and nucleic acid drug delivery.

Objective: To determine the internal relationships pf perceived discrimination and rejection sensitivity with social adjustment among college students with left behind experiences, so as to provide a reference for targeted prevention and intervention strategies for social adjustment issues in this population. Methods: A cluster random sampling method was used to select 2 999 college students from 3 universities in Qiqihar and Daqing, Heilongjiang Province. In October, 2024 (T1) and April 2025 (T2), the Discrimination Perception Questionnaire of college students, Rejection Sensitivity Questionnaire, and the Chinese College Student Adjustment Scale (CCSAS) were used to assess students perceptions of discrimination, rejection sensitivity, and social adjustment levels. Independent sample t-test was used for group comparisons. Traditional cross sectional comparisons and cross sectional network analysis were performed using T1 data for the core sample of 1 080 students with left behind experiences (T1). Longitudinal network analysis was performed using paired data from T1 and T2 ( n =1 024) and a preliminary cross lagged model was used to determine the relationships between variables. Sensitivity analysis was performed by including followup data from students without left behind experiences to test the robustness of the results. Results: After gender adjustment, students with leftbehind experiences had higher scores on discrimination perception (13.14±0.16) and rejection sensitivity (92.82±0.73) compared to the non left behind group (10.25±0.12) (89.12±0.55) while the social adjustment score (194.94±1.05) was lower than the non left behind group (202.82±0.79). The differences were statistically significant ( F =212.03, 16.52, 36.02, all P <0.01). Cross sectional network analysis showed that the "anticipated rejection likelihood" was the core node ( EI=-2.27 , BEI =-2.37), playing a key role in inter network connections and overall dynamic regulation. Longitudinal network comparison revealed statistically significant changes in the intensity centrality of the nodes "individual discrimination perception" and "anticipated rejection likelihood" (both P <0.05), while other nodes remained relatively stable. Cross lagged network analysis showed that the predictive effects of T1 on the variables at T2 were not statistically significant (maximum | r |=0.05, FDR corrected P >0.50), but the binomial test indicated a systematic positive correlation trend between the variables (66.7% positive correlation, P =0.04). Sensitivity analysis showed that the bridge effect of the "anticipated rejection likelihood" and "learning adjustment" nodes at T2 was more significant in the left behind group compared to the non left behind group. Conclusion The social adjustment issues of college students with left behind experiences require focused attention on the negative regulatory effect of "rejection cognition" and the positive regulatory effect of "learning adaptation".

Atherosclerosis is a multifocal, smoldering, immunoinflammatory disease caused by lipid accumulation. Acute cardio-cerebrovascular disease caused by AS is one of the most serious life threats in the world. Endothelial cell injury, vascular inflammatory stimulation, abnormal lipid metabolism and coagulation disorder are the main pathological mechanisms of AS. Thrombomodulin (TM) is a transmembrane glycoprotein mainly expressed on the surface of endothelium. It plays a key role in maintaining the dynamic equilibrium of the vascular system through its functions of anti-coagulation, anti-inflammation and cell protection. Recombinant human soluble thrombomodulin (rhsTM), a soluble form of human TM containing the extracellular domain of TM, might be effective in the treatment of AS. This review summarizes the structure and function of TM and the mechanism of rhsTM in the treatment of AS. Aiming to provide new ideas for the prevention and treatment of AS.

ObjectiveTo explore the application law of compound prescriptions containing Coptidis Rhizoma to diabetes and its complications based on data mining. MethodA total of 288 records on formulas containing Coptidis Rhizoma in the treatment of diabetes and its complications and the corresponding syndromes and symptoms were retrieved from the medical records of modern physicians， with 218 on the treatment of diabetes and 70 on the treatment of diabetes complications. The Traditional Chinese Medicine Inheritance Computing Platform （V3.0） was used or data mining on the compositions of the formulas. Moreover， it was employed for the frequency statistics， formula analysis， symptom analysis， association rules analysis， network visualization， and cluster analysis. ResultThe 218 formulas containing Coptidis Rhizoma for the treatment of diabetes involved 190 Chinese medicinals. A total of 12 syndromes showed the occurrence frequency ≥ 6， and the one with the highest frequency was deficiency of both qi and yin， followed by the syndrome of excessive heat in lung and stomach， syndrome of Yin deficiency and effulgent fire， and syndrome of excessive heat and fluid consumption. The dose of Coptidis Rhizoma for the treatment of diabetes ranged from 1.5-30 g， and the most frequently used doses were 10， 6， and 5 g. The medicinal was frequently applied for the traditional Chinese medicine symptoms of dry stool， dry mouth and tongue， and swift digestion with rapid hungering. Moreover， 26 core medicinal pairs， 17 association rules， 3 diagrams on medicinal relationship， and 3 core combinations were yielded. The 70 formulas containing Coptidis Rhizoma for the treatment of diabetes complications involved 184 Chinese medicinals， and the top 3 complications were diabetic nephropathy， diabetic peripheral neuropathy， and diabetic gastroenteropathy. The dose of Coptidis Rhizoma in the treatment of diabetes complications fell in the range of 2-15 g， and 10， 6， and 5 g were most frequently used. ConclusionFormulas containing Coptidis Rhizoma for the treatment of diabetes and its complications mainly target the syndrome of dampness-heat transforming into fire and the syndrome of excessive heat damaging yin. This study can serve as a reference for standard use of Coptidis Rhizoma in the prevention and treatment of diabetes and its complications.

Objective:To explore the effect of probiotics on reducing ventilator-associated pneumonia (VAP) in sepsis patients.Methods:A total of 94 cases were randomly (random number) divided into the probiotic group ( n = 46) and the control group ( n = 48). All of the patients were given enteral nutrition therapy by nasogastric tube within 24-72 h after admission. And patients in the probiotic group were given live combined bifidobacterium, lactobacillus and enterococcus powder besides the regular therapy. The incidence of VAP, bacteremia, mortality, mechanical ventilation time and length of ICU stay were compared between the two groups. Results:Compared with the control group, the incidences of VAP and bacteremia in the probiotics group were significantly lower (χ 2=4.763, P=0.029; χ 2=4.438, P=0.035). There were no significant differences in 28-day mortality and the length of hospital stay between the two groups (χ 2=2.02, P=0.167; t=1.29, P=0.208). Mechanical ventilation time in the probiotics group was significantly shorter than that in the control group ( t=2.16, P=0.038). The Log-Rank test showed that the time of VAP-free in the probiotics group was significantly longer than that in the control group ( P < 0.05). After adjusting for APACHEⅡ score and age, COX proportional risk model analysis showed that the RR values of the probiotics group and the control group for 28-day VAP were 0.18 (95% CI: 0.12-0.74, P=0.025) and 0.21 (95% CI: 0.19-0.95, P=0.042), respectively. Conclusions:Probiotics treatment can reduce the incidence of VAP in sepsis patients.

Objective:This study explored the correlation between Cardiovascular metabolic index (CMI) and hyperuricemia (HUA) in non-obese Chinese population.Methods:73 150 non-obese people who received routine physical examination between January 2014 to December 2017 were included in this cross-sectional study (from Jingjiang People's Hospital of Jiangsu Province, Hangzhou Aeronautical Sanatorium of Chinese Air Force, and Shanghai Changhai Hospital). The anthropometric indexes, lipid parameters including triglycerides, and high-density lipoprotein cholesterol, uric acid, and other clinical parameters were collected, and the CMI values were calculated from the waist-to-body ratio (WHtR). The correlation between CMI and HUA was analyzed by Logistic regression model.Results:Among 39 443 non-obese women, 5 825 patients were HUAs with a prevalence rate of 14.7%; among 33 707 non-obese men, 7 720 were HUAs with a prevalence rate of 22.9%. HUA had no significant association with Waist-to-Hip Ratio (WHR) and WHtR, but only with CMI. The highest quartile of women in CMI was 6.311(5.734, 6.947) and 6.785(6.092, 7.557) in male, P<0.01. Conclusion:CMI is significantly associated with HUA in non-obese Chinese population and is expected to become a new monitoring parameter for the prevention and management of HUA and gout.

Objective: To compare the clinical effect of conventional polyvinyl chloride (PVC) endotracheal tube with silicone wire reinforced endotracheal tube to prevent ventilator-associated pneumonia (VAP) in mechanical ventilation patients. Methods: A total of 240 mechanical ventilation patients in the ICU were enrolled in this study, which were divided into two groups, PVC endotracheal intubation group (PVC group, n=113) and wire reinforced endotracheal intubation group (WR group, n=127). Gender, age, APACHEⅡ score, one-time success rate of intubation, intubation time, the rate of changing endotracheal, ventilation time, rate of tracheotomy and the incidence of VAP were compare between the two groups. Predictive factors for VAP were identified by the univariate and multivariate analyses in step-wise logistic regression model. Results: The rate of changing endotracheal tube in the PVC group was lower than that in the WR group (χ²=5.785, P=0.016); the mechanical ventilation time in the PVC group was shorter than that in the WR group (t=2.180, P=0.018); and compared with the WR group, the PVC group had significantly lower incidence of VAP (χ²=6.215, P=0.012). The univariate analysis showed that the selection of PVC endotracheal tube, APACHE Ⅱ score and mechanical ventilation time were the significant risk factors for VAP (P < 0.05). Multivariate analysis showed that the different selection of endotracheal tube and mechanical ventilation time were independent influencing factors of VAP (P < 0.05). Conclusions PVC tracheal tube can effectively reduce the incidence of VAP in patients with mechanical ventilation.
