[Analysis of correlation between high expression of nucleoporin 85 (NUP85) and immune cell infiltration in hepatocellular carcinoma].

Objective To investigate the significance of nucleoporin 85 (NUP85) ex-pression in hepatocellular carcinoma (HCC) and analyze its relevance to immune response. Methods A comprehensive analysis was conducted using various online databases to assess the mRNA and protein expression of NUP85 in HCC, as well as its mutation status and prognostic diagnostic value. The immune relevance of NUP85 was evaluated using single-cell sequencing data and resources from the Tumor Immune Estimation Resource (TIMER) and the Gene Expression Profiling Interactive Analysis 2021 (GEPIA2021) databases. The drug sensitivity of NUP85 was analyzed through the Genomic Landscape of Cancer (GSCA) and the Clinical Bioinformatics Home. Co-expressed genes of NUP85 in HCC were filtered using the Hepatocellular Carcinoma Comprehensive Molecular Database (HCCDB), and the correlation between NUP85 and its related genes was analyzed using the R language "limma" package. The gene ontology (GO) functions, Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Set Enrichment Analysis (GSEA) of NUP85 and its related genes were performed using the R language "clusterProfiler" package. The Clinical Bioinformatics Home was utilized to construct heatmaps and prognostic risk scoring models for NUP85 and its related genes. Results NUP85 mRNA and protein expression were upregulated in HCC, showing high levels across dif-ferent stages and grades, which indicates a poor prognosis for patients. The mutation rate of NUP85 in HCC samples was 19%, significantly affecting the overall survival (OS), disease-specific survival (DSS), and progression-free survival (PFS) of patients. NUP85 was highly expressed in various immune cells, including macrophages, B cells, and T cells, and was positively correlated with the infiltration levels of multiple immune cells. The expression of NUP85 was significantly correlated with multiple drugs, such as Milademetan (PD0325901), a structural analog of Vemurafenib (PLX4720), and Regorafenib (PD0325901). The GO functions of NUP85 and its co-expressed genes were mainly enriched in organelle fission, nuclear division, and chromosome segregation, while the KEGG pathways were primarily enriched in the cell cycle and kinesin proteins. These factors significantly and unfavorably affected the OS of HCC patients, and the areas under the ROC curve (AUC) for the 1-year, 3-year, and 5-year OS prognostic diagnosis of HCC patients were all greater than 0.7. Conclusion The high expression of NUP85 in HCC is correlated with a poor prognosis and is related to various immune cells and drugs, making it a potential biomarker for di-agnosis, treatment, and prognosis in HCC.

Association of lifestyle and occupational exposure factors with human semen quality: a cross-sectional study of 1060 participants.

The incidence of male infertility (MI) is rising annually. However, the lifestyle and occupational exposure factors contributing to MI remain incompletely understood. This study explored the effects of self-reported lifestyle and occupational exposure factors on semen quality. Among 1060 subjects invited to participate, 826 were eligible. The participants' general characteristics, lifestyle, and occupational exposure factors were collected immediately before or after semen evaluation through an online questionnaire. Initially, univariate analysis was used to investigate the relationship between the abovementioned factors and semen quality. The results indicated significant associations between low semen quality and various factors, including age, BMI, infertility type and duration, abstinence time, semen and sperm parameters, smoking, alcohol consumption, irregular sleep habits, and frequent exposure to high temperatures and chemicals at work (p < 0.05). Then, multivariate analysis was conducted to identify factors independently associated with low semen quality. Adjustment for relevant confounders was achieved by including factors with a p-value < 0.25 from univariate analyses as covariates in the binomial and ordered logistic regression models. The results suggested that alcohol consumption was a positive factor for sperm concentration (odds ratio [OR] = 0.60; 95% confidence interval [CI] = 0.36-0.99; p = 0.045). The groups with a BMI ≥ 24 and <28 kg/m2 showed a significant decrease in sperm progressive motility when compared to the reference group (BMI < 24 kg/m2) (OR = 0.63; 95% CI = 0.46-0.87, p = 0.005). In addition, the groups that drank green tea <1 time/week (OR = 1.52, 95% CI = 1.05-2.2) and 1-4 times/week (OR = 1.61, 95% CI = 1.02-2.54) exhibited significantly increased sperm DFI values compared with the group that drank green tea 5-7 times/week. In conclusion, these findings underscore the importance of maintaining a normal weight and regularly consuming green tea for men.

Causal effects and metabolites mediators between immune cell and risk of breast cancer: a Mendelian randomization study.

Introduction: The incidence and mortality of female breast cancer remain high, and the immune microenvironment of breast cancer has undergone significant alterations. However, the impact of blood immune cell levels on the risk of breast cancer is not fully understood. Therefor this study aims to investigate the causal relationship between blood immune cell levels and the risk of breast cancer. Methods: A Mendelian randomization (MR) analysis was employed to assess the causal relationship between immune cells and the risk of breast cancer, as along with their potential mediating factors. Genetic statistics of metabolites breast cancer and immune cells were obtained from the GWAS Catalog, while the genome-wide association study (GWAS) statistics of breast cancer were extracted from the UK biobank. Two-sample MR analysis were performed using inverse-variance weighted (IVW) to ascertain the causal association between immune cells and the risk of breast cancer. Furthermore, 1,400 metabolites were analyzed for their mediating role between immune cells and the risk of breast cancer. Results: MR analysis through IVW method revealed that genetically predicted CD24+ CD27+ B cells were associated with a decreased risk of breast cancer (OR = 0.9978, 95% CI: 0.996-0.999, p = 0.001), while IgD- CD38+ B cells were linked to an increased risk of breast cancer (OR = 1.002, 95% CI: 1.001-1.004, p = 0.005). Additional CD14+ CD16+ monocytes were associated with an increased risk of breast cancer (OR = 1.000, 95% CI: 1.000-1.001, p = 0.005). Mediation analysis revealed a positive causal relationship between IgD- CD38+ B cells and Glycerate levels, with the latter also exhibiting a positive causal relationship with the risk of breast cancer (p < 0.05). Conversely, IgD- CD38+ B cells displayed a negative causal relationship with Succinoyltaurine levels, and the latter also demonstrated a negative causal relationship with the risk of breast cancer (p < 0.05). Conclusion: This MR study provides novel genetic evidence supporting a causal relationship between IgD- CD38+ B cells and the risk of BC. Moreover, it is identified that IgD- CD38+ B cells contribute to an increased risk of BC through both positive and negative mediation effects involving Glycerate and Succinoyltaurine.

Access to innovative anticancer medicines in China: a national survey on availability, price and affordability.

OBJECTIVES: This study aimed to investigate the availability, price, and affordability of nationally negotiated innovative anticancer medicines in China. DESIGN: Retrospective observational study based on data from a nationwide medical database. DATA SOURCES/SETTING: Quarterly data about the use of innovative anticancer medicines from 2020 to 2022 were collected from the Chinese Medicine Economic Information Network. This study covered 895 public general hospitals in 30 provincial administrative regions in China. Of the total hospitals, 299 (33.41%) were secondary and 596 (66.59%) were tertiary. MAIN OUTCOME MEASURES: The adjusted WHO and Health Action International methodology was used to calculate the availability and affordability of 33 nationally negotiated innovative anticancer medicines in the investigated hospitals. Price is expressed as the defined daily dose cost. RESULTS: On average, the total availability of 33 innovative anticancer medicines increased annually from 2020 to 2022. The median availability of all investigated medicines in tertiary hospitals from 2020 to 2022 was 24.04%, 33.60% and 37.61%, respectively, while the indicators in secondary hospitals were 4.90%, 12.54% and 16.48%, respectively. The adjusted prices of the medicines newly put in Medicare (in March 2021) decreased noticeably, with the decline rate ranging from 39.98% to 82.45% in 2021 compared with those in 2020. Most generic brands were priced much lower than the originator brands. The affordability of anticancer medicines has improved year by year from 2020 to 2022. In comparison, rural residents had lower affordability than urban residents. CONCLUSIONS: The overall accessibility of 33 nationally negotiated innovative anticancer medicines improved from 2020 to 2022. However, the overall availability of most anticancer medicines in China remained at a low level (less than 50%). Further efforts should be made to sufficiently and equally benefit patients with cancer.

Dendrobium officinale Polysaccharides as a Natural Functional Component for Acetic-Acid-Induced Gastric Ulcers in Rats.

Dendrobium officinale is an important edible and medicinal plant, with the Dendrobium officinale polysaccharide (DOP) being its primary active constituent, known for its diverse biological activities. In this study, DOP was extracted and characterized for its structural properties. The potential of DOP to ameliorate gastric ulcers (GUs) was investigated using an acetic-acid-induced GU model in rats. The results demonstrated that DOP exerted a multifaceted protective effect against GU, mitigating the deleterious impact on food intake and body weight in rats. DOP exhibited its protective action by attenuating cellular damage attributed to oxidative stress and inflammatory reactions mediated by enhanced activities of SOD, GSH, and GSH-PX, coupled with a downregulation in the expression of pro-inflammatory cytokines, including IL-1ß, IL-6, and TNF-α. Furthermore, DOP effectively inhibited apoptosis in gastric mucosa cells of acetic-acid-induced GU rat models and facilitated the self-repair of damaged tissues. Remarkably, the DOP-200 and DOP-400 groups outperformed omeprazole in reducing the expression of IL-6 and malondialdehyde (MDA) in tissues, as well as IL-1ß, IL-6, and TNF-α in serum. These groups also exhibited an improved expression of SOD in tissues and SOD, GSH, and GSH-PX in serum. A Western blot analysis of gastric mucosa demonstrated that the DOP-200 and DOP-400 groups significantly reduced the expression of NF-κBp65, phosphorylated NF-κBp65, FoxO3a, and Bim. The observed antagonism to GU appeared to be associated with the NF-κB cell pathway. Additionally, qRT-PCR results indicate that DOP reduced the mRNA transcription levels of IL-6, and TNF-α, which shows that the healing of GU is related to the reduction in the inflammatory reaction by DOP. However, the expression of EGF and VEGF decreased, suggesting that the mechanism of DOP inhibiting GU may not be directly related to EGF and VEGF, or there is an uncertain competitive relationship between them, so further research is needed.

Arenobufagin regulates the p62-Keap1-Nrf2 pathway to induce autophagy-dependent ferroptosis in HepG2 cells.

Hepatocellular carcinoma (HCC) is the most prevalent type of primary liver cancer, accounting for the overwhelming majority of malignant liver tumors. Therefore, how to effectively prevent and cure HCC has become a research hotspot. Many studies have shown that arenobufagin can induce apoptosis, ferroptosis, and autophagy of tumor cells. An increasing number of studies have shown that autophagy is closely linked to ferroptosis. In this study, HepG2 cells and BALB/c nude mice were used as research objects to explore the effect and preliminary mechanism of hepatoma cell autophagy and ferroptosis induced by arenobufagin. We found that arenobufagin can significantly inhibit tumor growth in vivo, and interestingly, we found that arenobufagin inhibited ferroptosis-related proteins Nrf2 and COX-2 in a dose-dependent manner and decreased the levels of reduced glutathione (GSH) and superoxide dismutase (T-SOD) in tissues, while increased the level of reduced malondialdehyde (MDA). In addition, we found that arenobufagin increased the levels of COX-2 and MDA in cells, decreased the levels of Nrf2, GSH, and T-SOD, increased the levels of tissue reactive oxygen species (ROS) and lipid ROS in a dose-dependent manner, and promoted ferroptosis in HepG2 cells. HepG2 cells were preprotected by autophagy inhibitor chloroquine (CQ) and ferroptosis inhibitor deferoxamine (DFO), and then treated with arenobufagin. It was found that CQ partially reversed the changes of COX-2 and Nrf2 expression and lipid peroxidation induced by arenobufagin-induced autophagy and HepG2 cells. Interestingly, CQ partially reversed the inhibition of arenobufagin on cytoplasmic junction protein (Keap1) and heme oxygenase-1 (HO-1) in p62-Keap1-Nrf2 pathway. At the same time, we found that the effect of arenobufagin on oxidative stress of HepG2 cells overexpressed by Nrf2 was significantly less than that of the control group. To sum up, arenobufagin promotes autophagy-dependent ferroptosis of HepG2 cells by inducing autophagy and regulating p62-Keap1-Nrf2 pathway. It is suggested that arenobufagin can be used as a potential intervention therapy.

Cinobufacini injection delays hepatocellular carcinoma progression by regulating lipid metabolism via SREBP1 signaling pathway and affecting macrophage polarization.

ETHNOPHARMACOLOGICAL RELEVANCE: Cinobufacini injection, an aqueous extract of the toad, is a commonly used anti-tumor animal herbal medicine in clinical practice. It has the effects of detoxifying, reducing swelling, and relieving pain. AIMS OF THE STUDY: To investigate the effects of Cinobufacini injection on hepatocellular carcinoma progression by regulating lipid metabolism and macrophage polarization in the tumor microenvironment and to identify the potential molecular mechanisms. MATERIALS AND METHODS: To establish the axillary transplantation tumor model of hepatocellular carcinoma Hepa1-6 in C57BL/6 mice, and to evaluate the inhibitory effect of Cinobufacini injection on hepatocellular carcinoma in vivo as well as drug delivery security. Combined metabolomics and transcriptomics analysis of the effect of Cinobufagin Injection on tumor microenvironment. An in vitro mouse co-culture model of peritoneal macrophages and Hepa1-6 cells was established to research the effects of Cinobufacini injection on macrophage polarization, hepatocellular carcinoma cell growth, migration, and changes in lipid metabolism. Cinobufacini injection inhibition of the AMPK/SREBP1/FASN signaling pathway regulating cholesterol metabolism and affecting macrophage polarization was examined using qRT-PCR, lentiviral transfection, immunofluorescence, and Western blot. RESULT: In vivo experiments demonstrated that Cinobufacini injection treatment significantly inhibited the growth of Hepa1-6 hepatomas, along with a reduction in cholesterol content and a decrease in the percentage of M2 macrophages in tumor tissue. In vitro, we found that Cinobufacini injection inhibits IL-4-induced M2 macrophage polarization, reduces the cholesterol content of Hepa1-6 cells in a co-culture system, and inhibits the promotion of hepatocellular carcinoma cells by M2 macrophages. In addition, successful overexpression of SREBP1 in Hepa1-6 cells showed more pronounced cellular activity whereas Cinobufacini injection inhibited this change and reduced intracellular lipid levels. CONCLUSION: Cinobufacini injection inhibits cholesterol synthesis within the tumor microenvironment via the AMPK/SERBP1/FASN signaling pathway, which in turn blocks the M2 polarization of macrophages, leading to the weakening of hepatocellular carcinoma growth and migration, and the promotion of its apoptosis. Our findings provide an important Introduction to understanding the molecular mechanism of Cinobufacini injection's anticancer activity and provide reliable theoretical and experimental support for its clinical application.

Paris polyphylla saponins II inhibits invasive, migration and epithelial-mesenchymal transition of melanoma cells through activation of autophagy.

Malignant melanoma is a kind of malignant tumor derived from normal epidermal melanocytes or original nevus cells. It has a high degree of malignancy, rapid progress, dangerous condition, and poor prognosis. In recent years, the innovation of traditional Chinese medicine has broadened the scope and effect of tumor treatment. It is a hotspot and breakthrough to find new anti-tumor invasion and migration drugs from natural plants or traditional Chinese medicine. This study explored the role of PPII in promoting autophagy to inhibit EMT of melanoma cells, the role of the PI3K/Akt signaling pathway in the invasion and migration of melanoma cells induced by PPII. We found that PPII effectively inhibited the proliferation, invasion and migration of melanoma B16 and B16F10 in vitro, and induced autophagy. We also established the xenograft tumor and metastatic tumor model of C57BL/6 mice with B16F10 cells. Results showed that PPII effectively inhibited the growth of transplanted tumors, induced autophagy and inhibited the expression level of EMT related protein; Metastasis experiment showed that PPII inhibited the invasion and migration of B16F10, the effect of inhibiting lung metastasis is the most significant. Further mechanism studies showed that the inhibition of PPII on melanoma invasion and migration is related to its induction of autophagy and then inhibition of EMT.

A UPLC-QTOF/MS-based hepatic tissue metabolomics approach deciphers the mechanism of Huachansu tablets-based intervention against hepatocellular carcinoma.

Huachansu (HCS) tablets, classified as well-known traditional Chinese medicine (TCM) preparation, have been proved to be effective in the treatment of hepatocellular carcinoma (HCC) in clinical studies. However, the underlying mechanism of HCS tablets against HCC has not been comprehensively elucidated. In this study, a rat model of HCC was established with diethylnitrosamine (DEN) inducer. The efficacy of HCS tablets against HCC was assessed through liver histopathological examination and evaluation of biochemical indicators. A metabolomics method based on UPLC-Q-TOF/MS combined with multivariate data analysis was established to identify differential metabolites related to the inhibition effect of HCS tablets on HCC, and then the relevant metabolic pathway analysis was performed to investigate the anti-HCC mechanisms of HCS tablets. The results showed that compared to the control group, the HCC model group showed a significant increase in the values of HCC-related biochemical indicators and the number of tumor nodules, indicating the successful establishment of the HCC rat model. Upon treatment with HCS tablets, the values of HCC-related biochemical indicators decreased, liver fibrosis and nuclear deformation were also significantly alleviated. A total of 15 differential metabolites associated with the anti-tumor effect of HCS tablets on HCC were screened and annotated through hepatic tissue metabolomics studies. Analysis of metabolic pathways revealed that the therapeutic effects of HCS tablets on HCC mainly involved the pentose and glucuronate interconversions and arachidonic acid metabolism. Further western blotting corroborated that the alteration in arachidonic acid (AA) level after the intervention of HCS tablets was related to the inhibition of cPLA2α expression in rat liver tissues. In conclusion, HCS tablets exhibit a certain anti-tumor effect on HCC, and the metabolomics method based on UPLC-Q-TOF/MS combined with further verification at the biochemical level is a promising way to reveal its underlying mechanism.

Causal association between constipation and risk of colorectal cancer: a bidirectional two-sample Mendelian randomization study.

Background: Colorectal cancer (CRC) is a globally significant health concern, necessitating effective preventive strategies through identifying modifiable risk factors. Constipation, characterized by infrequent bowel movements or difficulty passing stools, has been proposed as a potential CRC risk factor. However, establishing causal links between constipation and CRC remains challenging due to observational study limitations. Methods: Mendelian randomization (MR) utilizes genetic variants as instrumental variables, capitalizing on genetically determined variation to assess causal relationships. In this dual-sample bidirectional MR study, we extracted genetic data from independent cohorts with CRC (Include colon cancer and rectal cancer) and constipation cases. Genome-wide association studies (GWAS) identified constipation and CRC-associated genetic variants used as instruments to infer causality. The bidirectional MR analysis evaluated constipation's impact on CRC risk and the possibility of reverse causation. Results: Employing bidirectional MR, we explored the causal relationship between constipation and CRC using publicly available GWAS data. Analysis of constipation's effect on CRC identified 26 significant SNPs, all with strong instrumental validity. IVW-random effect analysis suggested a potential causal link [OR = 1.002(1.000, 1.004); P = 0.023], although alternative MR approaches were inconclusive. Investigating CRC's impact on constipation, 28 significant SNPs were identified, yet IVW analyses found no causal effect [OR = 0.137(0.007, 2.824); P = 0.198]. Other MR methods also yielded no significant causal association. We analyzed constipation separately from colon and rectal cancer using the same methodology in both directions, and no causal relationship was obtained. Conclusion: Our bidirectional MR study suggests a potential constipation-CRC link, with mixed MR approach outcomes. Limited evidence supports constipation causing CRC. Reliable instruments, minimal heterogeneity, and robust analyses bolster these findings, enriching understanding. Future research should explore additional factors to enhance comprehension and clinical implications.

Phycobiliprotein Peptide Extracts from Arthrospira platensis Ameliorate Nonalcoholic Fatty Liver Disease by Modulating Hepatic Lipid Profile and Strengthening Fat Mobilization.

Arthrospira platensis phycobiliprotein peptide extracts (PPEs) exhibit potential mitigative effects on hepatic steatosis. However, the precise role of PPEs in addressing high-fat-induced nonalcoholic fatty liver disease (NAFLD), as well as the underlying mechanism, remains to be elucidated. In this study, NAFLD was induced in rats through a high-fat diet (HFD), and the rats were subsequently treated with PPEs for a duration of 10 weeks. The outcomes of this investigation demonstrate that PPE supplementation leads to a reduction in body weight gain, a decrease in the accumulation of lipid droplets within the liver tissues, alterations in hepatic lipid profile, regulation of lipolysis-related gene expression within white adipose tissues and modulation of intestinal metabolites. Notably, PPE supplementation exhibits a potential to alleviate liver damage by manipulating neutral lipid metabolism and phospholipid metabolism. Additionally, PPEs appear to enhance fat mobilization by up-regulating the gene expression levels of key factors such as HSL, TGL, UCP1 and UCP2. Furthermore, PPEs impact intestinal metabolites by reducing the levels of long-chain fatty acids while concurrently increasing the levels of short-chain fatty acids. The findings from this study unveil the potential of PPE intervention in ameliorating NAFLD through the modulation of hepatic lipid profile and the reinforcement of the fat mobilization of intestinal metabolites. Thus, PPEs exhibit noteworthy therapeutic effects in the context of NAFLD.

An integrated model of CDCA5 and FOXM1 expression combined with a residual disease that predicts prognosis in ovarian cancer patients.

Ovarian cancer (OC) is the most prevalent type of gynecologic cancer, leading to global death. Unfortunately, less than half of patients diagnosed with this cancer survive for up to five years. The factor forkhead box M1 (FOXM1) is a crucial oncoprotein in ovarian cancer and is currently recognized as a potential therapeutic target. The role of the Cell division cycle-associated 5 (CDCA5) is critical for advancing different types of cancers. However, the significance of CDCA5 in OC from a clinical perspective is not well comprehended. This study aimed to build a risk prognosis model and assess the data supporting the prognostic usefulness of CDCA5 and FOXM1 expression in patients with OC. In OC, we found that CDCA5 and FOXM1 were expressed. To establish the existence of variables that were independently related to PFS and OS, Cox regression, data from clinics, and Kaplan-Meier analysis were used. A risk score model and nomogram were created using the independent prognostic parameters. The accuracy of the model's predictions was then evaluated using decision curve analysis (DCA), calibration curve, and receiver operating characteristic(ROC) analysis. Finally, the patients were separated into groups based on their cut-off value, and then the differences in survival were investigated. Significant correlations were found between OC and CDCA5, and FOXM1 expression levels (P <0.0001). Serous ovarian tumors (P=0.025) and even specific subgroups of high-grade serous ovarian tumors were shown to have elevated CDCA5 expression levels. In our database, FOXM1 expression levels were discovered to be related to intestinal metastases (P=0.014). In OC, the expression of FOXM1 was positively correlated with the overexpression of CDCA5 (rs=0.46, P<0.0001). The results of the multivariate analysis indicated that residual disease (RD) (P=0.005), CDCA5 expression level (P=0.028), and FOXM1 expression level (P<0.0001) were identified as independent prognostic factors for PFS. Additionally, RD (P=0.023) and FOXM1 expression level (P<0.0001) were identified as independent prognostic factors for OS. While the prediction model's performance with RD was poor (AUC=0.645 for PFS, AUC=0.650 for OS), the model's performance with tissue biomarkers was enhanced (AUC=0.797 for PFS, AUC=0.741 for OS). The nomogram and risk score method showed a benefit for prognosis prediction. In summary, poor outcomes are predicted by CDCA5, which is overexpressed in OC patients and has a positive correlation with the level of FOXM1 expression. An aid to prognosis prediction in patients with OC and a resource for therapy planning is a risk prognosis model based on CDCA5 and FOXM1 expression with RD.

Factors associated with postoperative muscle reconnection in children's congenital muscular torticollis.

Background: In prior studies, there has been no report of clinical observation of postoperative reconnection of the sternocleidomastoid muscle (SCM) in children with congenital muscular torticollis (CMT). Therefore, the objective of this study is to investigate the factors associated with postoperative reconnection of the SCM in children with CMT, and to provide clinical evidence. Methods: A retrospective study was conducted, wherein 83 CMT children without any missing data were followed up from November 2019 to June 2021. The age at the time of surgery, sex, preoperative and postoperative follow-up duration, laterality, neck mass history, preoperative physical therapy history, and severity type were recorded. The severity classification of CMT was based on clinical features and ultrasound images of SCM. The postoperative reconnection of SCM was measured. Results: Out of 83 patients, ten had postoperative reconnection. The rate of postoperative reconnection of SCM in children with CMT who had undergone unipolar SCM release surgery was 18.994 times higher than in patients who had not undergone such surgery. This difference was statistically significant [odds ratio (OR) =18.994, 95% confidence interval (CI): 1.583 to 227.897, P=0.020]. Conclusions: The history of SCM release surgery in CMT children can predict the postoperative reconnection of SCM, which will aid in determining the optimal surgical approach for recurrent CMT patients.

14-3-3ζ targets ß-catenin nuclear translocation to maintain mitochondrial homeostasis and promote the balance between proliferation and apoptosis in cisplatin-induced acute kidney injury.

Cisplatin is a chemotherapeutic agent that is used extensively to treat solid tumors; however, its clinical application is limited by side effects, especially nephrotoxicity. Cisplatin-induced acute kidney injury (AKI) is characterized by DNA damage, cell-cycle arrest, and mitochondrial oxidative stress. Recent research demonstrated that 14-3-3ζ plays an important role in cancers, nerve disease, and kidney disease, although the regulatory mechanisms underlying cisplatin-induced AKI have yet to be fully elucidated. In the present study, we found that 14-3-3ζ mRNA was upregulated in human kidney organoids (GSE145085) when treated with cisplatin; subsequently, this was confirmed in experimental mice. The application of a protein interaction inhibitor for 14-3-3 (BV02) resulted in a decline in renal function, along with apoptosis, mitochondrial dysfunction, and oxidative stress in cisplatin-induced AKI. Accordingly, the knockdown of 14-3-3ζ in cisplatin-treated NRK-52E cells led to increased apoptosis, cell-cycle arrest, the production of reactive oxygen species (ROS), and lipid dysbolism. Furthermore, the blockade of 14-3-3ζ, both in vivo and in vitro, suppressed ß-catenin and its nuclear translocation, thus downregulating expression of the downstream gene cyclin D1 in cisplatin-induced damage. In contrast, the overexpression of 14-3-3ζ alleviated the injury caused by cisplatin both in vivo and in vitro. Furthermore, a non-specific agonist of ß-catenin, BIO, reversed the effects of 14-3-3ζ knockdown in terms of cisplatin-induced damage in NRK-52E cells by activating ß-catenin. Next, we verified the direct interaction between 14 - 3-3ζ and ß-catenin by CO-IP and immunofluorescence. Collectively, these findings indicate that 14-3-3ζ protects against cisplatin-induced AKI by improving mitochondrial function and the balance between proliferation and apoptosis by facilitating the nuclear translocation of ß-catenin.

[Effect of mild moxibustion at 45 ℃ with different durations at "Zusanli" （ST36） on the inflammatory factors in the abdominal aorta of hyperlipidemia rats].

OBJECTIVE: To investigate the effects of mild moxibustion at 45°C on the chronic inflammatory response of the abdominal aorta in rats with hyperlipidemia and the effects of different moxibustion durations. METHODS: Thirty-six SD rats were randomly divided into the following groups： blank control group (2 weeks), model group (2 weeks), moxibustion group (2 weeks), blank group (4 weeks), model group (4 weeks), and moxibustion group (4 weeks). A model of hyperlipidemia with chronic inflammation was established through high-fat diet feeding for 8 weeks. Rats in the moxibustion groups received mild moxibustion treatment at bilateral "Zusanli"(ST36) at 45 °C, 10 min every time, once a day, for consecutive 2 or 4 weeks. The morphology of the abdominal aorta in each group was observed by using HE staining. Contents of serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), oxidized low-density lipoprotein (ox-LDL), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), endothelin-1 (ET-1) and the contents of nitric oxide (NO), ox-LDL, and ET-1 in the abdominal aorta were measured by using ELISA. Protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta of rats in each group were detected by using Western blot and real-time fluorescence quantitative PCR respectively. The positive expression of IL-6 in the abdominal aorta of rats was detected by Immunofluorescence. RESULTS: Compared to the blank control group, rats in the model group had increased contents of LDL, TC, TG, ox-LDL, VCAM-1, ICAM-1, IL-6, TNF-α, and ET-1 in the serum, increased contents of ox-LDL and ET-1 in the abdominal aorta, increased protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta(P<0.01, P<0.05, P<0.001), with decreased HDL content in the serum, decreased NO content in the abdominal aorta (P<0.01, P<0.05), as well as dark pink abdominal aorta, rough textures in the adventitia, media, and intima, and rough endothelial layer. Compared to the model group(2 weeks), LDL, ICAM-1, ET-1 contents in the serum, ox-LDL content in the abdominal aorta were decreased(P<0.05), while serum IL-6 and TNF-α contents, and NO content in the abdominal aorta were significantly increased(P<0.01, P<0.05), with smoother vascular walls, and relatively clear nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(2 weeks). Compared to the model group(4 weeks), contents of LDL, TC, TG, VCAM-1, ICAM-1, IL-6, TNF-α, ox-LDL, and ET-1 in the serum, ox-LDL and ET-1 contents in abdominal aorta, protein and mRNA expressions of IL-6 and TNF-α in the abdominal aorta were significantly decreased(P<0.05, P<0.01), while HDL content in the serum and NO content in the abdominal aorta were significantly increased(P<0.05, P<0.01), with smoother vascular walls, and relatively clear nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(4 weeks). In addition, content of HDL in the serum were significantly increased(P<0.05), while TNF-α content in the serum, protein expression of IL-6 in the abdominal aorta were significantly decreased (P<0.001, P<0.05), with smoother vascular walls, and clearer nucleus and surrounding tissue structures of abdominal aorta in the moxibustion group(4 weeks), in comparison with the moxibustion group(2 weeks). CONCLUSION: Mild moxibustion of 45 °C at ST36 can improve vascular endothelial damage and inflammatory response induced by high-fat diet by regulating serum lipids, vascular tone, adhesion molecules, and inflammatory factors, of which the effect of moxibustion intervention for 4 weeks is more significant.

Acupoint Thread Embedding Combined With Wenshen Bugu Decoction for the Treatment of Aromatase Inhibitor-Associated Musculoskeletal Symptom Among Postmenopausal Breast Cancer Patients: Study Protocol of a Randomized Controlled Trial.

BACKGROUND: Aromatase inhibitors (AIs) are recommended as the preferred therapy for postmenopausal women with hormone receptor-positive (HR+) breast cancer. As a result, aromatase inhibitor-associated musculoskeletal symptom (AIMSS) have become a major problem leading to therapy discontinuation and decreased quality of life in patients receiving adjuvant AIs treatment. Multiple therapies have been attempted, but have yielded limited clinical results. This study will be performed to determine whether acupoint thread embedding (ATE) combined with Wenshen Bugu Decoction can effectively treat AIMSS, so as to improve the AIs medication compliance of postmenopausal breast cancer patients. METHODS: This study will utilize a randomized, 2 parallel groups controlled trial design. A total of 128 eligible postmenopausal breast cancer women with AIMSS will be randomized to receive a 12-week treatment with Wenshen Bugu Decoction alone (control group) or in combination with ATE (treatment group) in a 1:1 ratio. The primary outcome will be the 12 week Brief Pain Inventory Worst Pain (BPI-WP) score. The secondary outcome measures will include response rate, Brief Pain Inventory-Short Form (BFI-SF), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Functional Assessment of Cancer Therapy-Endocrine Symptom (FACT-ES), Functional Assessment of Cancer Therapy-Breast (FACT-B), bone marrow density (BMD), blood markers of bone metabolite, Morisky medication adherence scale-8 (MMAS-8), credibility and expectancy, and survival outcomes. DISCUSSION: This trial may provide clinical evidence that ATE combined with Wenshen Bugu Decoction can be beneficial for treating AIMSS among postmenopausal breast cancer survivors. Our findings will be helpful to enhance the quality of life and reduce the occurrence of AIs withdrawal.

Targeting TCF19 sensitizes MSI endometrial cancer to anti-PD-1 therapy by alleviating CD8+ T cell exhaustion via TRIM14-IFN-ß axis.

Immune checkpoint blockade (ICB) therapies display clinical efficacy in microsatellite instable (MSI) endometrial cancer (EC) treatment, the key mechanism of which is reversing T cell exhaustion and restoration of anti-tumor immunity. Here, we demonstrate that transcription factor 19 (TCF19), one of the most significantly differentially expressed genes between MSI and microsatellite stable (MSS) patients in The Cancer Genome Atlas (TCGA)-EC cohort, is associated with poor prognosis and immune exhaustion signature. Specifically, TCF19 is significantly elevated in MSI EC, which in turn promotes tripartite motif-containing 14 (TRIM14) transcription and correlates with hyperactive signaling of the TANK-binding kinase 1 (TBK1)-interferon regulatory factor 3 (IRF3)-interferon ß (IFN-ß) pathway. The TCF19-TRIM14 axis promotes tumorigenicity under non-immunological background, and the enhanced downstream secretion of IFN-ß facilitates CD8+ T cell exhaustion through cell differentiation reprogramming. Finally, using humanized models, we show that a combination of TCF19 inhibition and ICB therapy demonstrates more effective anti-tumor responses. Together, our study indicates that targeting TCF19 is a potent strategy for alleviating CD8+ T cell exhaustion and synergizing with ICB in tumor treatment.

Identification and quantitative analysis of the chemical constituents of Gandouling tablets using ultra-high-performance liquid chromatography with quadrupole time-of-flight mass spectrometry.

Gandouling tablets are used in a clinical agent for the treatment of hepatocellular degeneration; however, their chemical constituents have not been elucidated. Here, we screened and identified the chemical constituents of Gandouling tablets using ultra-high-performance liquid chromatography (UHPLC)-quadrupole time of flight/mass spectrometry. A method for the quality evaluation of Gandouling tablets was developed by combining the UHPLC fingerprints and the simultaneous quantitative analysis of multiple active ingredients. For fingerprint analysis, 20 shared peaks were identified to assess the similarities among the 10 batches of Gandouling tablets and the similarity was >0.9. The levels of nine representative active ingredients were simultaneously determined to ensure consistency in quality. A total of 99 chemical components were identified, including 18 alkaloids, 20 anthraquinones, 13 flavonoids, 11 phenolic acids, 9 polyphenols, 7 phenanthrenes, 5 sesquiterpenes, 3 curcuminoids, 2 lignans, 2 isoflavones, 2 dianthranones, and 7 other components. The retention times, molecular formulae, and secondary fragmentation information of these compounds were analyzed, and the cleavage pathways and characteristic fragments of some of the representative compounds were elucidated. This systematic analysis used to identify the chemical components of Gandouling tablets lays the foundation for its further quality control and research on their pharmacodynamic substances.

An integrated analytical strategy to decipher the metabolic profile of alkaloids in Compound Kushen injection based on UHPLC-ESI-QTOF/MSE.

Compound Kushen injection (CKI) is a kind of sterilised water-soluble traditional Chinese medicine preparation that has been used for the clinical treatment of a variety of cancers (hepatocellular carcinoma, lung cancer, etc.) for 19 years. However, to date, the metabolism-related study on CKI in vivo has not been conducted.An integrated analytical strategy was established to investigate the metabolic profile of alkaloids of CKI in rat plasma, urine, and faeces based on ultra-high performance liquid chromatography-electrospray quadrupole time-of-flight mass spectrometry in MSE mode (UHPLC-ESI-QTOF/MSE).Nineteen prototype alkaloids (including 12 matrine-type alkaloids, 2 cytisine-type alkaloids, 3 lupinine-type alkaloids, and 2 aloperine-type alkaloids) of CKI were identified in vivo. Furthermore, 71 metabolites of alkaloids (including 11 of lupanine-related metabolites, 14 of sophoridine-related metabolites, 14 of lamprolobine-related metabolites, and 32 of baptifoline-related metabolites) were tentatively characterised. Metabolic pathways involved in the metabolism of phase I (include oxidation, reduction, hydrolysis, and desaturation), phase II (mainly include glucuronidation, acetylcysteine or cysteine conjugation, methylation, acetylation, and sulphation), and associated combination reactions.The integrated analytical strategy was successfully used to characterise the prototype alkaloids and their metabolites of CKI in vivo, and the results laying a foundation for further study its pharmacodynamic substances.
