Colorectal cancer(CRC) is one of the most common malignant tumors worldwide, primarily originating from recurrent inflammatory bowel disease(IBD). Therefore, blocking the inflammation-cancer transformation in the colon has become a focus in the early prevention and treatment of CRC. The inflammation-cancer transformation in the colon involves multiple types of cells and complex pathological processes, including inflammatory responses and tumorigenesis. In this complex pathological process, immune cells(including non-specific and specific immune cells) and non-immune cells(such as tumor cells and fibroblasts) interact with each other, collectively promoting the progression of the disease. In traditional Chinese medicine(TCM), inflammation-cancer transformation in the colon belongs to the categories of dysentery and diarrhea, with the main pathogenesis being cold and heat in complexity. This paper first elaborates on the complex molecular mechanisms involved in the inflammation-cancer transformation process in the colon from the perspectives of inflammation, cancer, and their mutual influences. Subsequently, by comparing the pathogenic characteristics and clinical manifestations between inflammation-cancer transformation and the TCM pathogenesis of cold and heat in complexity, this paper explores the intrinsic connections between the two. Furthermore, based on the correlation between inflammation-cancer transformation in the colon and the TCM pathogenesis, this paper delves into the importance of the interaction between inflammation and cancer. Finally, it summarizes and discusses the clinical and basic research progress in the TCM intervention in the inflammation-cancer transformation process, providing a theoretical basis and treatment strategy for the treatment of CRC with integrated traditional Chinese and Western medicine.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To explore the correlation of different HBV DNA loads with peripheral blood lymphocyte subsets and interleukin-6 (IL-6) in patients with chronic hepatitis B.Methods:A cross-sectional study was conducted. A total of 519 patients with chronic hepatitis B admitted to the Fifth Medical Center of the General Hospital of the People′s Liberation Army from April 2019 to June 2024 were included. The patients were divided into high, medium, and low viral load groups and a negative group based on HBV DNA load. Another 100 healthy individuals who underwent physical examinations during the same period were recruited as the control group. The quantities of peripheral blood lymphocyte subsets and IL-6 levels were compared among the groups. Meanwhile, alanine aminotransferase (ALT) levels were recorded and compared among the groups. The correlation of HBV DNA levels with lymphocyte subsets and IL-6 was analyzed using Pearson correlation analysis.Results:HBV DNA loads were negatively correlated with the counts of CD3 +, CD4 +, CD8 +, CD19 +, and CD56 + lymphocyte subsets (correlation coefficients r were -0.483, -0.508, -0.524, -0.573, and -0.561, respectively; all P<0.001) and positively correlated with IL-6 levels ( r=0.862, P<0.05). Compared with the control group, the counts of each lymphocyte subset were higher in the high, medium, and low viral load groups ( P<0.05). In the HBV DNA-negative chronic hepatitis B group, the counts of CD8 + and CD19 + lymphocyte subsets were significantly higher [712.32(526.00,898.64) and 495.62(345.74,645.50) cells/μl] than those in the control group [612.10(479.89,744.31) and 470.32 (396.00,544.64) cells/μl] ( P<0.05). Conclusion:The degree of HBV replication activity in patients with chronic hepatitis B is associated with the immune status of the body, and negatively correlated with the quantities of lymphocyte subsets and positively correlated with IL-6 levels.

Objective To investigate the effects of individual social capital on depressive symptoms among older couples across different socioeconomic statuses(SES)using the actor-partner interdependence model(APIM).Methods A cross-sectional survey was conducted using a staged sampling method,involving 245 older couples from communities in Chengdu,China.Data on household SES,individual social capital,and depression levels were collected.Pearson correlation analysis was performed to examine the relationships among these variables,and the APIM was applied to analyze the actor and partner effects of individual social capital on depression across different SES groups.Results The prevalence of depressive symptoms was 38.2%.Individual social capital of the husbands and wives was negatively correlated with their personal depression levels(actor effects among the husbands:r=-0.218,P<0.01;those among the wives:r=-0.323,P<0.01)and with the spouse's depression levels(partner effects:husband on wife,r=-0.185,P<0.01;wife on husband:r=-0.183,P<0.01).Among high-SES couples,the husband's social capital had a protective effect only on his own depression(β=-0.242,95%CI:-0.462 to-0.054).In contrast,among low-SES couples,the wife's individual social capital exhibited a protective effect against depressive symptoms both for herself(β=-0.658,95%CI:-0.848 to-0.456)and for the husband(β=-0.379,95%CI:-0.630 to-0.143).Conclusion Individual social capital among older couples demonstrates both actor and partner effects on depression levels,with distinct pathways of influence observed across different levels of SES.These findings highlight the importance of considering socioeconomic status when designing interventions to enhance social capital and improve mental health outcomes in older couples.

Objective To evaluate the improvement effect and mechanism of propofol on neuropathic pain(NP)model rats induced by spinal nerve ligation(SNL).Methods An SNL rat model was established,and 30 success-fully modeled rats were randomly divided into SNL group,propofol+SNL group and propofol+7-N1(7-nitroindazole)+SNL group(n=10 each),with sham group as control(n=10).After propofol intervention,Von Frey method was applied to detect mechanical hypersensitivity in rats.The hot claw foot analgesic device was applied to detect the la-tent period of the heat contraction foot reflex.Enzyme-linked immunosorbent assay(ELISA)method was applied to detect the expression level of interleukin-6(IL-6)and interferon-γ(IFN-γ)in the spinal cord of rats.RT-qPCR method was used to detect the mRNA expressions of suppressor of cytokine signaling 3(SOCS3),arginase-1(Arg-1)and cluster of differentiation 68(CD68)in the spinal dorsal horn.Western blot was applied to detect the expression level of proteins related to the nitric oxide/cyclic guanosine monophosphate(NO/cGMP)signaling pathway.Results Compared with the sham group,the mechanical foot contraction reflex threshold,thermal foot contraction reflex latency,and the expression level of Arg-1 mRNA,endothelial nitric oxide synthase(eNOS)and soluble gua-nylate cyclase(sGCa)proteins were significantly reduced in the SNL group(P＜0.05),the level of IL-6 and IFN-γ and the expression level of SOCS3,CD68 mRNA and inducible nitric oxide synthase(iNOS)protein were signifi-cantly increased(P＜0.05).Compared with the SNL group,the mechanical foot reflex threshold,thermal foot reflex latency of rats in the propofol+SNL group,the expression level of Arg-1 mRNA,eNOS and sGCa protein were sig-nificantly increased(P＜0.05),the level of IL-6 and IFN-γ and the expression of SOCS3,CD68 mRNA and iNOS protein were all decreased(P＜0.05).The NO/cGMP signaling pathway inhibitor 7-N1 reversed the improvement effect of propofol on SNL rats(P＜0.05).Conclusions Propofol alleviates NP and injury in SNL rats by activating the NO/cGMP signaling pathway.
