Using updated National Health and Nutrition Examination Survey (NHANES) follow-up data, and a large nationwide representative sample of adult U.S. citizens, the aim of this study was to explore the relationship between dietary flavonol intake, all-cause and cause-specific mortality risks. In this prospective cohort study based on NHANES (2007–2008, 2009–2010, and 2017–2018), a total of 11,679 participants aged 20 years and above were evaluated. The amount and type of food taken during a 24-h dietary recall were used to estimate dietary flavonol intake, which includes total flavonol, isorhamnetin, kaempferol, myricetin, and quercetin. Each analysis of the weighted data was dealt with in accordance with the NHANES reporting requirements' intricate stratification design. The Cox proportional risk regression model or Fine and Gray competing risks regression model were applied to evaluate all-cause and cause-specific mortality risks, respectively. The follow-up period was calculated using the time interval between the baseline and the death date or December 31, 2019 (whichever occurs first). Each data analysis was performed between October 1, 2023, and October 22, 2023. Dietary flavonol intake included total flavonol, isorhamnetin, kaempferol, myricetin, and quercetin. Up to December 31, 2019, National Death Index (NDI) mortality data were used to calculate mortality from all causes as well as cause-specific causes. A total of 11,679 individuals, which represents 44,189,487 U.S. non-hospitalized citizens, were included in the study; of these participants, 49.78% were male (n = 5816), 50.22% were female (n = 5, 863); 47.56% were Non-Hispanic White (n = 5554), 18.91% were Non-Hispanic Black (n = 2209), 16.23% were Mexican American (n = 1895), and 17.30% were other ethnicity (n = 2021); The mean [SE] age of the sample was 46.93 [0.36] years, with a median follow-up of 7.80 years (interquartile range, 7.55–8.07 years). After adjusting covariates, Cox proportional hazards models and fine and gray competing risks regression models for specific-cause mortality demonstrated that total flavonol intake was associated with all-cause (HR 0.64, 95% CI 0.54–0.75), cancer-specific (HR 0.45, 95% CI 0.28–0.70) and CVD-specific (HR 0.67, 95% CI 0.47–0.96) mortality risks; isorhamnetin intake was associated with all-cause (HR 0.72, 95% CI 0.60–0.86), and cancer-specific (HR 0.62, 95% CI 0.46–0.83) mortality risks; kaempferol intake was associated with all-cause (HR 0.74, 95% CI 0.63–0.86), and cancer-specific (HR 0.62, 95% CI 0.40–0.97) mortality risks; myricetin intake was associated with all-cause (HR 0.77, 95% CI 0.67–0.88), AD-specific (HR 0.34, 95% CI 0.14–0.85), and CVD-specific (HR 0.61, 95% CI 0.47–0.80) mortality risks; quercetin intake was associated with all-cause (HR 0.66, 95% CI 0.54–0.81), cancer-specific (HR 0.54, 95% CI 0.35–0.84), and CVD-specific (HR 0.61, 95% CI 0.40–0.93) mortality risks; there was no correlation observed between dietary flavonol intake and DM-specific mortality. According to the current study, all-cause, AD, cancer, and CVD mortality risks declined with increased dietary flavonoid intake in the U.S. adults. This finding may be related to the anti-tumor, anti-inflammatory, and anti-oxidative stress properties of flavonol.

Background Cancer is still a leading cause of mortality. Over the years, cancer therapy has undergone significant advances driven by advancements in science and technology. A promising area of drug discovery in this field involves the development of therapeutic targets for cancer treatment. The urgent need to identify new pharmacological targets arises from the impact of tumor resistance on the effectiveness of current medications. Specifically, the RPS6KB2 gene on chromosome 11 has been implicated in cell cycle regulation and exhibits higher expression levels in tumor tissue. Given this association, there is a potential for this gene to serve as a target for cancer treatment. Methods We conducted an analysis using the GTEx, TCGA, and CCLE databases to explore the relationship between RPS6KB2 and immune infiltration, the tumor microenvironment (TME), microsatellite instability (MSI), and more. Cell proliferation was assessed using EDU detection, while cell invasion and migration were evaluated via wound healing and Transwell assays. Additionally, western blot analysis was employed to measure expression of Bax, Bcl-2, MMP2, MMP9, PCNA, and proinflammatory factors. Results Through data analysis and molecular biology methods, our study carefully examined the potential role of RPS6KB2 in cancer therapy. The data revealed that RPS6KB2 is aberrantly expressed in most cancers and is associated with poor prognosis. Further analysis indicated its involvement in cancer cell apoptosis and migration, as well as its role in cancer immune processes. We validated the significance of RPS6KB2 in hepatocellular carcinoma (HCC), highlighting its capacity to upregulate proinflammatory cytokines. Conclusion Our research indicates that RPS6KB2 is a prognostic biomarker associated with immune infiltration in cancer that can affect antitumor immunity by increasing secretion of proinflammatory factors, providing a potential drug target for cancer treatment.

Tumors are one of the main causes of death in people with illnesses. The therapy of tumors has evolved in recent years along with science and technology, and one such area of drug discovery is developing therapeutic targets for tumor treatment. Finding new pharmacological targets is increasingly urgent since tumor resistance affects how well current medications work. The chromosome 11 gene RPS6KB2 has been implicated in cell cycle regulation and has been found to express at much greater levels in tumor tissue. The association between RPS6KB2 and tumors raises the possibility that this gene could be a target for cancer treatment. Therefore, our study used data analysis and molecular biology methods to examine the potential involvement of RPS6KB2 in tumor therapy carefully. The data demonstrated that RPS6KB2, which has a poor prognosis, is aberrantly expressed in most tumors. Further data showed that RPS6KB2 is involved in tumor cell apoptosis and migration. RPS6KB2 also plays a role in tumor immune processes. We further verified the role of RPS6KB2 in liver cancer, and found that RPS6KB2 can up-regulate pro-inflammatory cytokines. In summary, RPS6KB2 maybe a novel therapeutic target.

Background: To evaluate whether the addition of taxanes to platinum and fluoropyrimidines in adjuvant chemotherapy would result in longer survival than platinum plus fluoropyrimidines in gastric cancer patients who received D2 gastrectomy. Methods: Data of patients with gastric adenocarcinoma who received D2 gastrectomy and adjuvant chemotherapy with platinum plus fluoropyrimidines or taxanes, platinum plus fluoropyrimidines was retrospectively collected and analyzed. 1:1 Propensity score matching analysis was used to balance baseline characteristics between two groups. Survival curves were estimated using Kaplan-Meier method, and the differences were compared using the log-rank test. Results: Four hundred twenty-five patients in the platinum plus fluoropyrimidines group and 177 patients in the taxanes, platinum plus fluoropyrimidines group were included into analysis. No statistical differences in disease-free survival and overall survival were observed between two groups. After propensity score matching, 172 couples of patients were matched, the baseline characteristics were balanced. The median disease-free survival were 15.8 months (95% CI, 9.3~22.4) in the platinum plus fluoropyrimidines group and 22.6 months (95% CI, 15.9~29.4) in the taxanes, platinum plus fluoropyrimidines group (HR = 0.63; 95% CI, 0.48~0.85; P = 0.002). The median overall survival was 25.4 months for patients in the platinum plus fluoropyrimidines group (95% CI, 19.4~31.3) and 33.8 months (95% CI, 23.5~44.2) for those in the taxanes, platinum plus fluoropyrimidines group (HR = 0.68; 95% CI, 0.53-0.87; log-rank test, P = 0.002). Conclusions: For gastric adenocarcinoma patients, the adjuvant triplet combination of taxanes, platinum, and fluoropyrimidines regimen after D2 gastrectomy was superior to platinum plus fluoropyrimidines regimen in disease-free survival as well as overall survival. Trial registration: This project has been registered in the Chinese Clinical Trial Registry (ChiCTR1800019978).

BackgroundTo evaluate whether the addition of taxane to platinum and fluoropyrimidines in adjuvant chemotherapy would result in longer survival than platinum plus fluoropyrimidines in patients who underwent curative gastrectomy.MethodsThis study retrospectively analyzed survival for patients with stage Ⅱ-Ⅲ gastric adenocarcinoma who received curative gastrectomy and adjuvant chemotherapy with platinum plus fluoropyrimidines (PF group) or taxanes and platinum plus fluoropyrimidines (TPF group). Survival curves were estimated using the Kaplan-Meier method, and the differences were compared using the log-rank test.ResultsBaseline characteristics were balanced between the PF group and TPF group. The median disease-free survival (DFS) was 14.9 months (95% CI: 11.0-18.8) in the PF group and 13.8 months (95% CI: 9.3-18.3) in the TPF group (HR=0.90, 95% CI: 0.63-1.29, log-rank test, P=0.560). The median overall survival (OS) was 30.0 months for patients in the PF group (95% CI: 24.5-35.5) and 25.6 months (95% CI: 22.3-28.9) for those in the TPF group (HR=0.93, 95% CI: 0.64-1.35, log-rank test, P=0.705).ConclusionFor stage Ⅱ-Ⅲ gastric adenocarcinoma, the adjuvant triple combination of TPF regimen after curative gastrectomy did not demonstrate survival benefit compared to the PF regimen.

This study investigated the function of SMAD3 (SMAD family member 3) in regulating PAX6 (paired box 6) in non-small cell lung cancer. First, qRT-PCR was employed to detect SMAD3 expression in cancer tissues along with normal tissues and four cell lines, including BEAS-2B, H125, HCC827 and A549 cells. SMAD3 was knocked down by small interference RNA (siRNA), and then its expression was determined via qRT-PCR and Western blot analysis. The correlation between SMAD3 and PAX6 was determined by double luciferase reporter experiments and chromatin immunoprecipitation (ChIP) assay. Cell viability was evaluated by CCK-8 and colony forming assays, while cell migration and invasion were detected by Transwell analysis. SMAD3 and PAX6 were upregulated in lung cancer tissues and cancer cells. Knocking down SMAD3 and PAX6 by transfection with siRNAs specifically suppressed the expression of SMAD3 and PAX6 mRNA and protein levels. SMAD3 could promote PAX6 transcriptional activity by binding to its promoter. Reduced expression of SMAD3 led to the downregulation of PAX6 mRNA and protein levels along with decreased cell migration, invasion, proliferation and viability in A549 and HCC827 cells. PAX6 overexpression altered the si-SMAD3-induced inhibition of cell migration, invasion, proliferation and viability in A549 and HCC827 cells. Additionally, PAX6 knockdown alone also repressed the cell migration, invasion, proliferation and viability of the cell lines. SMAD3 promotes the progression of non-small cell lung cancer by upregulating PAX6 expression.

Interleukin-22 (IL-22) is an IL-10 family cytokine that was recently discovered to be released by T helper 17 (Th17) cells, Th22 cells, etc. Recently, there is emerging evidence that IL-22 is involved in the development and pathogenesis of psoriasis. For instance, IL-22 can inhibit keratinocyte terminal differentiation and can induce psoriasis-like epidermis alterations; serum IL-22 levels were correlated with the disease severity of psoriasis patients, and IL-22 mRNA was positively expressed in the psoriatic skin lesions, but negatively expressed in the normal controls. All these findings suggest that IL-22 may be implicated in psoriasis; therapeutics targeting IL-22 may have promise as a potential therapeutic target for treating psoriasis. In the present review, we summarize recent advances on the role of IL-22 in the pathogenesis and treatment of psoriasis.

Background: The aim of this study was to investigate the analgesic effects of intravenous flurbiprofen axetil for the refractory pain in cancer patients. Methods: 2109 patients were screened from the department of medical oncology, the first affiliated hospital of Anhui medical university in China between October of 2007 and October of 2008. Thirty-seven cases of cancer patients who had bad effect from anaesthetic drugs were received administration of intravenous flurbiprofen axetil with dose of 50 mg/5 ml/day. The pain score was evaluated for pre- and post- treatment by Pain Faces Scale criteria, and the side effects were also observed. Results: Intravenous flurbiprofen axetil increased the analgesic effects. The total effective rate was 92%. The side effects, such as abdominal pain, alimentary tract bleeding which were found in using NSAIDs or constipation, nausea, vomit, sleepiness which were found in using opioid drugs did not be found. Conclusion: Intravenous flurbiprofen axetil could provide better analgesia effects and few side effects to patients with refractory cancer pain. It could also increase analgesia effects when combining with anesthetic drugs in treatment of moderate or severe pain, especially breakthrough pain, and suit to patients who can not take oral drugs for the reason of constipation and psychosomatic symptoms.
