Objective To investigate the efficacy of externally applied mirabilite combined with infrared irradiation in promoting wound healing following biliary tract surgery.Methods Patients who underwent open surgery for biliary tract disease in our department between January 2022 and April 2025 were randomly assigned to one of three groups:(1)Combination group(n=60),which received postoperative wound treatment with mirabilite application combined with infrared irradiation;(2)Mirabilite group(n=60),treated with mirabilite application alone;and(3)Infrared group(n=60),treated with infrared irradiation alone.The primary outcomes included wound healing grade on postoperative day 7,pain intensity measured on days 3,5,and 7,and wound healing status up to discharge.For cases with suboptimal healing,the duration required for complete healing following intervention was documented.Secondary outcomes encompassed length of postoperative hospital stay and Vancouver Scar Scale(VSS)scores—assessing scar pigmentation,thickness,vascularity,and pliability—evaluated at 3 months postoperatively.Results The combination group exhibited significantly lower rates of poor wound healing,shorter postoperative hospital stays,improved VSS scores—particularly in terms of scar thickness and pliability—and reduced pain levels on the 3rd and 5th postoperative days compared to the other two groups(P<0.05).Conclusions The combined use of mirabilite and infrared irradiation for surgical incisions following biliary tract surgery represents an effective,economical,and readily accessible adjuvant therapy.It significantly reduces the incidence of impaired wound healing and effectively alleviates early postoperative pain,thereby demonstrating strong potential for clinical promotion.

With the development of medical technology, the survival rate of cancer patients continues to improve, and the number of stoma patients is increasing day by day. Self-management refers to patients monitoring and managing their own diseases to maintain and improve physical health. Good self-management ability can enhance patient treatment compliance, reduce the incidence of stoma and surrounding complications, improve health outcomes, and raise patient quality of life. This article reviews the research progress on self-management of stoma patients, with the aim of providing reference for research on self-management of stoma patients.

The symptoms of prostate cancer and the complications caused by treatment have a serious impact on the quality of life of prostate cancer patients. Conducting symptom assessment on patients is beneficial for judging disease progression and prognosis, and can provide a basis for symptom management and subsequent treatment, thereby improving their quality of life. This article reviews the symptom assessment tools for prostate cancer, including their evaluation content, reliability and validity, scoring methods, application status, and evaluation. The aim is to provide reference for the selection and development of symptom assessment tools for prostate cancer patients.

Objective:To investigate the role of miR-581 overexpression on the proliferation of human colorectal cancer cell line SW620. Methods:The expression group,colorectal cancer SW620 cells were transfected with recombinant lentivirus vector ( LV-miR-581) and miR-581 mimics(miR-581),the negative control group were transfected with negative control lentiviral vector (LV-GFP) and negative control mimics (vector).

Up-regulation of miR-581 markedly enhanced human colorectal cancer SW620 cells proliferation than those in the cells transfected with control vector ( P<0. 05 ) . Conclusion: Forced expression of miR-581 accelerates the proliferation of colorectal cancer SW620 cells.

Objective:To study the expression and regulation of TLR2/4 in mycobacterium tuberculosis heat shock proteins 16. 3 (mycobacterium tuberculosis heat shock proteins 16. 3,MTB Hsp16. 3) effect on mouse bone marrow-derived macrophages in vitro. Methods:Bone marrow cells were isolated from tibia and femurs of BALB/c mice and incubated with GM-CSF,then detected the expression of CD11b and F4/80 with flow cytometry and observed morphology. The M0 macrophages were stimulated with MTB Hsp16. 3 for 0 h,12 h,24 h,36 h,48 h and 72 h. Real-time PCR detected the expression of TLR2/4 in intracellular at different time point. Silencing macrophages cell surface TLR2/4 molecules by siRNA technology which stimulated with MTB Hsp16. 3 for 0 h,12 h,24 h,36 h,48 h and 72 h. Real-time PCR detected the expression of TLR2/4,Ym-1,Fizz1,IL-10,TNF-α,iNOS and TGF-βin intracellular at different time point. Results:Morphology analysis showed that MTB Hsp16. 3 stimulated macrophages were round cells stretching out pseudopodia,whereas MTB Hsp16. 3 stimulated silencing TLR2/4 macrophages had elongated fibroblastoid. Real time PCR detected the expression of TLR2/4 were upregulated after MTB Hsp16. 3 stimulated M0 macrophages. MTB Hsp16. 3 stimulated silencing TLR2/4 macrophages the expression of IL-6, TNF-α, iNOS were upregulated, whereas IL-10, TGF-β, Ym-1 and Fizz1 were downregulated. Conclusion:MTB Hsp16. 3 may stimulated M0 macrophages to M2 macrophages and suppress M1 macrophages through binding with TLR2/4 receptor,which may be involved the progresss of MTB evaded macrophage phagocytosis.

Objective To study the cytochemical changes of hepatocytes in mice exposed to hypoxia. Methods The mice were divided into two groups(n=45, all males, hypoxia group=36, control group=9). The mice of the hypoxia group lived in hypoxia (O 2:10%). Using imaging analytical instrument LEICA-500IW, We observed cytochemical changes of the hepatocytes. The PAS, LDH, cytochrome oxidase, Mg 2+ dependent ATPase activity of hepatocytes was assayed. Results Compared with the controls, the LDH activity of hepatocytes increased dramatically, the longer the hypoxic time, the higher the LDH activity of the hepatocytes; the cytochrome oxidase activity of hepatocytes decreased sharply, the longer the hypoxic time, the lower the cytochrome oxidase activity of the hepotocytes.Conclusion Hypoxia can injury the hepatocytes of the mice and result in sharp changes of the hepatic cytochemistry.;
