OBJECTIVE To analyze the influential factors for clinical efficacy of polymyxin B combined with other antibiotics in the treatment of carbapenem-resistant Acinetobacter baumannii (CRAB) pulmonary infection. METHODS A retrospective analysis was conducted on the clinical data of patients with CRAB pulmonary infection in our hospital from May 2021 to October 2024. Information such as age, gender, admitting department, infection status, underlying medical conditions, mechanical ventilation time, combination anti-infective treatment regimens, and the Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE-Ⅱ) score 24 h before medication was compiled. Based on the effectiveness of the treatment, patients were divided into treatment-effective group and treatment-ineffective group. Univariate analysis and multivariate Logistic regression analysis were employed to identify independent factors influencing clinical efficacy. RESULTS A total of 156 patients were included, and 108 patients were treated effectively, with an effective rate of 69.23%. The results of univariate analysis indicated that there were statistically significant differences between 2 groups in terms of the duration of mechanical ventilation time, APACHE-Ⅱ score 24 h before medication, the number of complication types, the proportion of abnormal coagulation function, anti-infective treatment course, and hospital stay before medication (P<0.05). The results of multivariate Logistic regression analysis showed that APACHE-Ⅱ score≥15 points 24 h before medication [OR=2.965, 95%CI (1.284, 6.845), P=0.020], mechanical 20251606) ventilation time≥10 d [OR=3.577, 95%CI (1.185, 10.793), P=0.037] and hospital stay≥14 d before medication [OR=2.422, 95%CI (1.036, 5.654), P=0.041] were independent 15120420253@139.com risk factors, and anti-infective treatment course>7 d was a protective factor [OR=0.445, 95%CI (0.221, 0.895), P=0.043]. CONCLUSIONS This study shows that the effective rate of polymyxin B combined with other antibiotics in the treatment of CRAB pulmonary infection is less than 70%. The mechanical ventilation time≥10 d, APACHE-Ⅱ score≥15 points 24 h before medication, and hospital stay≥14 d before medication may lead to treatment failure, whereas anti-infective treatment course>7 d may be associated with treatment success.

Hepatocellular carcinoma (HCC), as the sixth most common malignant tumor worldwide, poses a serious threat to human health due to its insidious onset and high mortality rate. This article reviews the molecular mechanisms and intervention strategies of gut microbiota (GM) homeostasis in the development and progression of HCC, in order to provide new ideas for the intervention and treatment of HCC. Studies have shown that GM dysbiosis, intestinal leakage, microbial-associated molecular pattern, bacterial translocation, and metabolic products play key roles in the progression of HCC. GM imbalance may lead to immune escape, thereby promoting tumor cell proliferation and metastasis. This article elaborates on the association between GM and HCC, deeply analyzes the mechanism of action of GM in the development and progression of HCC, investigates the role of bile acid-related metabolites, short-chain fatty acid-related metabolites, and other metabolites in HCC, and explores the strategies for targeting GM in the treatment of HCC, including probiotics, prebiotics, antibiotics, Toll-like receptor 4 antagonists, and fecal microbiota transplantation. This article emphasizes that maintaining the integrity of the intestinal barrier and GM homeostasis is of great significance in the prevention and treatment of HCC, which provides a direction for developing new diagnosis and treatment strategies.

OBJECTIVE To systematically evaluate the influential factors for the clinical efficacy of tigecycline in the treatment of severe infections caused by multidrug-resistant Gram-negative bacteria (MDR-GNB). METHODS Retrieved from PubMed, Embase, The Cochrane Library, CNKI database, Wanfang database and VIP database, the studies about the influential factors for the clinical efficacy of tigecycline in the treatment of adult patients with severe infections caused by MDR-GNB from the database construction to April 30, 2025. After screening literature, extracting data and evaluating the quality of literature, systematic review was performed by using RevMan 5.3 software. RESULTS A total of 14 studies involving 2 033 patients were included, of which 1 355 patients showed effective treatment outcomes. The meta-analysis results showed that Acute Physiology and Chronic Health Evaluation (APACHE)-Ⅱ > 20 [OR=4.50, 95%CI (2.28, 8.85), P<0.001], malignant tumor [OR=1.96, 95%CI (1.41, 2.72), P<0.001], hemodialysis [OR=2.09, 95%CI (1.40, 3.12), P<0.001], septic shock [OR=3.07, 95%CI (2.00, 4.72), P<0.001], mechanical ventilation [OR=2.31, 95%CI (1.57, 3.39), P<0.001], coagulation dysfunction [OR= 3.03, 95%CI (2.09, 4.37), P<0.001], glucocorticoids use>3 days [OR=2.26, 95%CI (1.14, 4.45), P=0.020], and longer hospitalization time before using tigecycline [OR=3.33, 95%CI (1.34, 8.30), P=0.010] were risk factors for the clinical efficacy of tigecycline in treatment of severe infections caused by MDR-GNB. Tigecycline initial double-dose regimen [OR=0.23, 95%CI (0.13, 0.42), P<0.001], combination therapy [OR=0.15, 95%CI (0.05, 0.48), P=0.001], and prolonged treatment course [OR=0.91, 95%CI (0.88, 0.95), P<0.001] were protective factors. CONCLUSIONS There are many influential factors for the clinical efficacy of tigecycline in the treatment of severe infections caused by MDR-GNB, among which APACHE-Ⅱ score>20, malignant tumor, hemodialysis, septic shock, mechanical ventilation, coagulation dysfunction, glucocorticoids>3 d and longer hospitalization time before using tigecycline before tigecycline (No.20251606) use are risk factors; tigecycline double dose, combined medication and longer treatment course are protective factors.

OBJECTIVES:
To explore the association of the expression of WW domain-containing ubiquitin E3 ligase 1 (WWP1) with immune infiltration in tumor microenvironment (TME) of ovarian cancer.
METHODS:
Ovarian cancer patient data from The Cancer Genome Atlas (TCGA) were used to analyze the association of WWP1 expression with patient prognosis. TISCH2 was utilized to analyze the changes in immune cell subtypes in TME of metastatic tumor and after chemotherapy. The impact of WWP1 on immune cell infiltration, somatic copy number alterations of WWP1 and evolution of immune cell subtypes was evaluated using TIMER and TIGER pseudo-time analysis. A deep learning model was used to analyze TCGA pathological images to investigate the effect of WWP1 on TME of ovarian cancer. RNA-seq analysis was conducted to identify the differentially expressed genes in WWP1-overexpressing SKOV3 cells and validate immune infiltration. Multicolor immunofluorescence assay was used to analyze the immune markers in SKOV3 and SKOV3/DDP cell xenografts in nude mice.
RESULTS:
The patients with high WWP1 expression levels had significantly lower overall survival rate (P=0.0012). High WWP1 expression levels and Stage IV disease were both associated with a poor prognosis (P<0.05). In metastatic ovarian cancer or after chemotherapy, the percentages of malignant tumor cells and tumor-associated fibroblasts increased in the TME, accompanied by elevated WWP1 levels. WWP1 expression level was positively correlated with pro-tumorigenic immunosuppressive cells (r=0.1323-0.3955, P<0.05) and negatively with tumor-inhibiting immune cells (r=-0.1949- -0.1333, P<0.05). Specific copy number alterations of WWP1 also influenced CD8+ T cell percentage and neutrophil infiltration levels in the TME. RNA-seq analysis of WWP1-overexpressing SKOV3 cells and immunofluorescence assay of the tumor-bearing mice yielded findings consistent with those of bioinformatics analysis.
CONCLUSIONS
WWP1 may serve as a prognostic biomarker and a potential target for immune regulation in the TME of ovarian cancer.

Breast cancer (BC) is one of the most prevalent malignant tumors affecting women worldwide, with its incidence rate continuously increasing. As a result, treatment strategies for this disease have received considerable attention. Research has highlighted the crucial role of the Hedgehog (Hh) signaling pathway in the initiation and progression of BC, particularly in promoting tumor growth and metastasis. Therefore, molecular targets within this pathway represent promising opportunities for the development of novel BC therapies. This study aims to elucidate the therapeutic mechanisms by which natural compounds modulate the Hh signaling pathway in BC. By conducting a comprehensive review of various natural compounds, including polyphenols, terpenes, and alkaloids, we reveal both common and unique regulatory mechanisms that influence this pathway. This investigation represents the first comprehensive analysis of five distinct mechanisms through which natural compounds modulate key molecules within the Hh pathway and their impact on the aggressive behaviors of BC. Furthermore, by exploring the structure-activity relationships between these compounds and their molecular targets, we shed light on the specific structural features that enable natural compounds to interact with various components of the Hh pathway. These novel insights contribute to advancing the development and clinical application of natural compound-based therapeutics. Our thorough review not only lays the groundwork for exploring innovative BC treatments but also opens new avenues for leveraging natural compounds in cancer therapy.

Objective To explore the effects of combined exposure to bisphenol A (BPA) and high-fat diet on liver lipid metabolism and hepatocyte senescence in mice, and to elucidate the potential mechanisms of the onset and development of non-alcoholic fatty liver disease (NAFLD). Methods Specific pathogen free C57BL/6J mice were randomly divided into six groups, with 10 mice with equal numbers of each sex in each group. The mice in the control group and the simple BPA group were fed with regular diet, while others four groups of mice were fed with high-fat diet. At the same time, the mice in the simple BPA group were intragastric administered with BPA at a dose of 50 μg/kg body weight, while the mice in the low-, medium- and high-dose BPA+high-fat groups were intragastric administered with BPA at doses of 5, 50 and 500 μg/kg body weight respectively. The mice in the control group and the high-fat group were intragastric administered with the same volume of corn oil once per day for 90 consecutive days. Liver tissues were subjected to hematoxylin-eosin (HE) and Oil Red O staining. Liver coefficients and lipid-stained area ratios were calculated. Serum level of total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, and the activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined using an automatic biochemical analyzer. The hepatic tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-10 levels were quantified by enzyme-linked immunosorbent assay. The relative expression of cholesterol regulatory element binding protein 1 (SREBP1), CCAAT enhancer binding protein α, P16, and phosphorylated histone H2AX (γ-H2AX) in liver tissues was detected using Western blotting. The interaction effect of the combined exposure to BPA and high-fat diet was observed based on the result of mice in the control group, the simple high-fat group, the simple BPA group, and the medium-dose BPA group+high-fat group (the combined exposure group) using a 2×2 factorial design. The results of mice in the simple high-fat group and the low-, medium-, and high-dose BPA+high-fat groups were used to observe the effect of BPA exposure dose under high-fat diet conditions. Results i) The interactive effect of combined exposure to BPA and high fat. The HE and Oil Red O staining results indicated that the combined exposure to BPA and high-fat diet successfully established NAFLD in mice. The interactive effect of combined exposure to BPA and high-fat diet on serum ALT activity and the relative expression of P16 in the liver tissue of female mice, as well as the serum ALT and AST activities and the relative expression of SREBP1 in the liver tissue of male mice was significant (all P<0.05). Specifically, the serum ALT activity of male mice in the combined exposure group was higher than that in the simple high-fat group (P<0.05), while the ALT activity in the serum of female mice in the combined exposure group was lower than that in the simple BPA group (P<0.05). The relative expression of SREBP1 protein in the liver tissue of male mice in the combined exposure group was higher than that in the control group, the simple high-fat group, and the simple BPA group (all P<0.05). For the other indicators, there were no significant differences in the interactive effect of combined exposure to BPA and high-fat diet (all P>0.05). ii) Dose effects of BPA exposure. The HE and Oil Red O staining result showed that the degree of vacuolar steatosis in the liver of female and male mice of medium- and high-dose BPA + high-fat groups was aggravated, and the range of inflammatory cell infiltration was expanded when compared with same-sex mice in the simple high-fat group. The serum ALT activity and the fat stained area ratio, as well as the relative expression of P16 in liver tissue of female mice in high-dose BPA + high-fat group increased (all P<0.05), while the level of IL-10 in liver tissue decreased (P<0.05), compared with the female mice in simple high-fat group. The serum ALT activity, the TNF-α level in liver tissue, and the relative expression of SREBP1, P16 and γ-H2AX proteins in liver tissue of male mice in high-dose BPA + high-fat group increased (all P<0.05), while the IL-6 level in liver tissue decreased (P<0.05), compared with the male mice in simple high-fat group. For the female or male mice in the low- and medium-dose BPA + high-fat groups, only some of the above indicators showed significant changes (all P<0.05). Conclusion The combined exposure to BPA and high-fat diet has a synergistic effect on the onset and development of NAFLD. The mechanism may be related to inducing cellular senescence and modulation of lipid synthesis pathways, thereby affecting liver steatosis. The exposure dose of BPA may affect the synergistic effect.

Corneal transplantation is an effective treatment for corneal blindness, and it is the only hope for patients with corneal blindness. Cornea has no blood vessels and no lymphatic vessels, which is called immune privilege organ, so the success rate of corneal transplantation is significantly higher than that of other organ transplantation, but the rejection reaction after corneal transplantation is still the main reason for the failure of corneal transplantation. The directional movement of immune cells to lymphoid tissue and inflammatory sites is the mainly immune response after organ transplantation. And the regulatory T cells(Treg)play a key role in immune regulation, which can induce immune tolerance by regulating and inhibiting the activation of effector T cells and reduce the rejection reaction after corneal transplantation. In addition, this review also discussed the effectiveness of applying cordyceps sinensis extract FTY720 to enhance the function of Treg. Based on this, we briefly reviewed the sources, mechanism of action and treatment of Treg after corneal transplantation, so as to provide some reference for the subsequent clinical application transformation and basic research.

ObjectiveTo investigate the possible mechanism of Ruyi Heibai Power (如意黑白散, RHP) in the treatment of vitiligo. MethodsTwenty-four C57BL/6 mice were randomly divided into blank group, model group, high-dose and low-dose RHP groups, with 6 mice in each group. Model group, high- and low-dose RHP groups were all applied hydroquinone to establish vitiligo animal model. After modeling, High- and low-dose RHP groups were given 7.02 g/kg and 2.34 g/kg of RHP by gavage, respectively, while the blank group and model group were intragastrically given 10ml/kg of normal saline, once a day for 36 days. After administration, the skin lesions were observed with naked eye, and HE staining was used to observe the melanin content of the skin lesions. Immunohistochemistry was used to determine the expression of CD3+ and CD8+ T cells in skin tissue. Immunofluorescence staining was used to measure the expression of programmed death receptor 1 (PD-1) in the skin lesion tissue. RT-PCR was used to detect programmed cell death ligand 1 (PD-L1) mRNA expression. ELISA was used to detect serum superoxide dismutase (SOD), tumor necrosis factor (TNF-α), and tyrosinase (TYR) levels. ResultsCompared to those in the blank group, the skin of the mice in the model group was pale, and the melanin content was significantly reduced under the microscope after HE staining; the rate of excellent and good skin lesions decreased, and the melanin granules in the cells around the epidermis and hair follicles decreased significantly; the expression of CD3+ and CD8+ T cells in skin tissue increased significantly, and the expressions of PD-L1 mRNA and PD-1 decreased; the content of TYR decreased, while the content of SOD and TNF-α increased (P<0.05). Compared to those in the model group, the skin color of high- and low-dose RHP groups were deepened, and the melanin content increased; the rate of excellent and good skin lesions increased, as well as the melanin granules in the spinous cell layer, basal cells and hair follicles; the expression of CD3+ and CD8+ T cells in the skin lesions decreased, while PD-L1 mRNA and PD-1 expression increased; the content of TYR increased, while the content of SOD and TNF-α decreased (P<0.05). Compared to the low-dose RHP group, the high-dose group had a larger pigment recovery area in the modeling area, an increased rate of excellent and good skin lesions, an increase in spinous cell layer, basal cells, and hair follicle melanin granules, a decrease in CD3+ and CD8+ T cells expression, an increase in the expression of PD-L1 mRNA and PD-1, an elevated TYR content, and decreased SOD and TNF-α contents (P<0.05). ConclusionRHP can increase skin melanin content of vitiligo mice.The mechanism of action may be related to activating the PD-1/PD-L1 signaling pathway, and then reducing the destruction of melanocytes by T cell-mediated autoimmunity.
