Decoding the molecular landscape: A novel prognostic signature for uveal melanoma unveiled through programmed cell death-associated genes.

Uveal melanoma (UM) is a rare but aggressive malignant ocular tumor with a high metastatic potential and limited therapeutic options, currently lacking accurate prognostic predictors and effective individualized treatment strategies. Public databases were utilized to analyze the prognostic relevance of programmed cell death-related genes (PCDRGs) in UM transcriptomes and survival data. Consensus clustering and Lasso Cox regression analysis were performed for molecular subtyping and risk feature construction. The PCDRG-derived index (PCDI) was evaluated for its association with clinicopathological features, gene expression, drug sensitivity, and immune infiltration. A total of 369 prognostic PCDRGs were identified, which could cluster UM into 2 molecular subtypes with significant differences in prognosis and clinicopathological characteristics. Furthermore, a risk feature PCDI composed of 11 PCDRGs was constructed, capable of indicating prognosis in UM patients. Additionally, PCDI exhibited correlations with the sensitivity to 25 drugs and the infiltration of various immune cells. Enrichment analysis revealed that PCDI was associated with immune regulation-related biological processes and pathways. Finally, a nomogram for prognostic assessment of UM patients was developed based on PCDI and gender, demonstrating excellent performance. This study elucidated the potential value of PCDRGs in prognostic assessment for UM and developed a corresponding risk feature. However, further basic and clinical studies are warranted to validate the functions and mechanisms of PCDRGs in UM.

Detection of fucosylated extracellular vesicles miR-4732-5p related to diagnosis of early lung adenocarcinoma by the electrochemical biosensor.

Our preliminary investigation has identified the potential of serum fucosylated extracellular vesicles (EVs) miR-4732-5p in the early diagnosis of lung adenocarcinoma (LUAD) by a fucose-captured strategy utilizing lentil lectin (LCA)-magnetic beads and subsequent screening of high throughput sequencing and validation of real-time quantitative polymerase chain reaction (RT-qPCR). Considering the relatively complicated procedure, expensive equipment, and stringent laboratory condition, we have constructed an electrochemical biosensor assay for the detection of miR-4732-5p. miR-4732-5p is extremely low in serum, down to the fM level, so it needs to be detected by highly sensitive electrochemical methods based on the Mg2+-dependent DNAzyme splitting nucleic acid lock (NAL) cycle and hybridization chain reaction (HCR) signal amplification. In this study, signal amplification is achieved through the dual amplification reactions using NAL cycle in combination with HCR. In addition, hybridized DNA strands bind to a large number of methylene blue (MB) molecules to enhance signaling. Based on the above strategy, we further enhance our signal amplification strategies to improve detection sensitivity and accuracy. The implementation of this assay proceeded as follows: initially, miR-4732-5p was combined with NAL, and then Mg2+-dependent DNAzyme splitted NAL to release auxiliary DNA (S1) strands, which were subsequently captured by the immobilized capture probe DNA (C1) strands on the electrode surface. Following this, abundant quantities of DNA1 (H1) and DNA2 (H2) tandems were generated by HCR, and S1 strands then hybridized with the H1 and H2 tandems through base complementary pairing. Finally, MB was bonded to the H1 and H2 tandems through π-π stacking interaction, leading to the generation of a signal current upon the detection of a potential capable of inducing a redox change of MB by the electrode. Furthermore, we evaluated the performance of our developed electrochemical biosensor assay. The results demonstrated that our assay is a reliable approach, characterized by its high sensitivity (with a detection limit of 2.6 × 10-17 M), excellent specificity, good accuracy, reproducibility, and stability. Additionally, it is cost-effective, requires simple operation, and is portable, making it suitable for the detection of serum fucosylated extracellular vesicles miR-4732-5p. Ultimately, this development has the potential to enhance the diagnostic efficiency for patients with early-stage LUAD.

Role of pattern recognition receptors in the development of MASLD and potential therapeutic applications.

Metabolic dysfunction-associated steatotic liver disease (MASLD) has become one of the most prevalent liver diseases worldwide, and its occurrence is strongly associated with obesity, insulin resistance (IR), genetics, and metabolic stress. Ranging from simple fatty liver to metabolic dysfunction-associated steatohepatitis (MASH), even to severe complications such as liver fibrosis and advanced cirrhosis or hepatocellular carcinoma, the underlying mechanisms of MASLD progression are complex and involve multiple cellular mediators and related signaling pathways. Pattern recognition receptors (PRRs) from the innate immune system, including Toll-like receptors (TLRs), C-type lectin receptors (CLRs), NOD-like receptors (NLRs), RIG-like receptors (RLRs), and DNA receptors, have been demonstrated to potentially contribute to the pathogenesis for MASLD. Their signaling pathways can induce inflammation, mediate oxidative stress, and affect the gut microbiota balance, ultimately resulting in hepatic steatosis, inflammatory injury and fibrosis. Here we review the available literature regarding the involvement of PRR-associated signals in the pathogenic and clinical features of MASLD, in vitro and in animal models of MASLD. We also discuss the emerging targets from PRRs for drug developments that involved agent therapies intended to arrest or reverse disease progression, thus enabling the refinement of therapeutic targets that can accelerate drug development.

Dihydroartemisinin-driven selective anti-lung cancer proliferation by binding to EGFR and inhibition of NRAS signaling pathway-induced DNA damage.

Chemotherapeutic agents can inhibit the proliferation of malignant cells due to their cytotoxicity, which is limited by collateral damage. Dihydroartemisinin (DHA), has a selective anti-cancer effect, whose target and mechanism remain uncovered. The present work aims to examine the selective inhibitory effect of DHA as well as the mechanisms involved. The findings revealed that the Lewis cell line (LLC) and A549 cell line (A549) had an extremely rapid proliferation rate compared with the 16HBE cell line (16HBE). LLC and A549 showed an increased expression of NRAS compared with 16HBE. Interestingly, DHA was found to inhibit the proliferation and facilitate the apoptosis of LLC and A549 with significant anti-cancer efficacy and down-regulation of NRAS. Results from molecular docking and cellular thermal shift assay revealed that DHA could bind to epidermal growth factor receptor (EGFR) molecules, attenuating the EGF binding and thus driving the suppressive effect. LLC and A549 also exhibited obvious DNA damage in response to DHA. Further results demonstrated that over-expression of NRAS abated DHA-induced blockage of NRAS. Moreover, not only the DNA damage was impaired, but the proliferation of lung cancer cells was also revitalized while NRAS was over-expression. Taken together, DHA could induce selective anti-lung cancer efficacy through binding to EGFR and thereby abolishing the NRAS signaling pathway, thus leading to DNA damage, which provides a novel theoretical basis for phytomedicine molecular therapy of malignant tumors.

LINC00330/CCL2 axis-mediated ESCC TAM reprogramming affects tumor progression.

BACKGROUND: Tumor-associated macrophages (TAMs) significantly influence the progression, metastasis, and recurrence of esophageal squamous cell carcinoma (ESCC). The aberrant expression of long noncoding RNAs (lncRNAs) in ESCC has been established, yet the role of lncRNAs in TAM reprogramming during ESCC progression remains largely unexplored. METHODS: ESCC TAM-related lncRNAs were identified by intersecting differentially expressed lncRNAs with immune-related lncRNAs and performing immune cell infiltration analysis. The expression profile and clinical relevance of LINC00330 were examined using the TCGA database and clinical samples. The LINC00330 overexpression and interference sequences were constructed to evaluate the effect of LINC00330 on ESCC progression. Single-cell sequencing data, CIBERSORTx, and GEPIA were utilized to analyze immune cell infiltration within the ESCC tumor microenvironment and to assess the correlation between LINC00330 and TAM infiltration. ESCC-macrophage coculture experiments were conducted to investigate the influence of LINC00330 on TAM reprogramming and its subsequent effect on ESCC progression. The interaction between LINC00330 and C-C motif ligand 2 (CCL2) was confirmed through transcriptomic sequencing, subcellular localization analysis, RNA pulldown, silver staining, RNA immunoprecipitation, and other experiments. RESULTS: LINC00330 is significantly downregulated in ESCC tissues and strongly associated with poor patient outcomes. Overexpression of LINC00330 inhibits ESCC progression, including proliferation, invasion, epithelial-mesenchymal transition, and tumorigenicity in vivo. LINC00330 promotes TAM reprogramming, and LINC00330-mediated TAM reprogramming inhibits ESCC progression. LINC00330 binds to the CCL2 protein and inhibits the expression of CCL2 and downstream signaling pathways. CCL2 is critical for LINC00330-mediated TAM reprogramming and ESCC progression. CONCLUSIONS: LINC00330 inhibited ESCC progression by disrupting the CCL2/CCR2 axis and its downstream signaling pathways in an autocrine fashion; and by impeding CCL2-mediated TAM reprogramming in a paracrine manner. The new mechanism of TAM reprogramming mediated by the LINC00330/CCL2 axis may provide potential strategies for targeted and immunocombination therapies for patients with ESCC.

To Investigate the Influence of Smoking Cessation Intention and Common Downstream Variants of HDAC9 Gene on Large Artery Atherosclerotic Cerebral Infarction.

Objective: To investigate the association of smoking cessation intention and single nucleotide polymorphism of HDAC9 gene with LAA-S in Han people in Hainan province. Methods: A case-control study was conducted. Six single nucleotide polymorphisms (SNPS) of HDAC9 gene were genotyped by SNPscan genotyping technique in 248 patients with LAA-S and 237 controls in Hainan Han population. SNP loci (rs10227612, rs12669496, rs1548577, rs2074633, rs2526626, and rs2717344) were genotyped, and the genotype and allele frequencies were compared between the case and control group. At the same time, the distribution of smoking between the case and control group was compared, and the 3-year and 7-year follow-up smoking cessation between the case and control group was compared, so as to find out the effects of smoking cessation intention and HDAC9 SNP on LAA-S. Results: (1) The GT genotype at rs10227612, GG genotype at rs2717344, and GA genotype at rs1548577 in the case group were significantly higher than those in the control group, and the differences were statistically significant. (2) There were significant differences in the distribution of smoking between the case and control group (P < 0.05), and there were significant differences in the smoking cessation after 3 years and 7 years of follow-up between the case and control group (P < 0.05). The intention to quit smoking was positively correlated with the incidence of LAA-S. Conclusion: (1) The rs10227612, rs1548577, rs2074633, rs2717344 of HDAC9 gene may be significantly related to atherosclerotic cerebral infarction of great arteries in Hainan Han population, while rs12669496 and rs2526626 may not be related. (2) According to the statistics of smoking in the case and control group, smoking was related to large artery atherosclerotic cerebral infarction, and the intention to quit smoking was a very important factor affecting the success of smoking cessation.

Clinical Efficacy of Percutaneous Osteoplasty Under Fluoroscopy and Cone-Beam CT Guidance for Painful Sternal Metastases: A Case Series.

Background: Although percutaneous osteoplasty (POP) has been widely accepted and is now being performed for the treatment of painful bone metastases outside the spine. It is emerging as one of the most promising procedures for patients with painful bone metastasis who are unsuitable for surgery or who show resistance to radiotherapy and/or analgesic therapies. However, there are only scarce reports regarding osteoplasty in painful sternal metastases. Subjects and Method: We report four patients with sternal metastases suffered with severe pain of anterior chest wall. The original tumors included lung cancer and thyroid cancer. For the initially pain medication failing, all the four patients received POP procedure under fluoroscopic and cone-beam CT (CBCT) guidance, and obtained satisfying resolution of painful symptoms at 6-month postop follow-up. Conclusion: POP is a safe and effective treatment for pain caused by metastatic bone tumors in the sternum. In practice, however, percutaneous puncture of pathologic sternal fractures can be a challenge because of the long flat contour and the defacement by lytic tumor of bony landmarks. We find that the use of fluoroscopic and CBCT can facilitate POP for flat bone fractures with displacing the trajectory planning, needle advancement, and cement delivery in time.

Long-Term Follow-Up of Combination Therapy with Sintilimab and Anlotinib in Gallbladder Follicular Dendritic Cell Sarcoma: A Rare Case Report.

Follicular dendritic cell sarcoma (FDCS) is a rare malignant neoplasm for which a standardized treatment approach has yet to be established. The prevailing therapeutic strategy typically involves resection followed by adjuvant chemotherapy or radiation. This case report details the long-term follow-up of a 59-year-old Chinese male diagnosed with gallbladder FDCS and liver metastases. The patient received a combination therapy of sintilimab and anlotinib, resulting in a substantial partial response (PR) lasting for a noteworthy duration of 30 months. Notably, this is the first documented instance of gallbladder FDCS with liver metastases being treated with PD-1 antibody and antiangiogenic agents as first-line therapy. These findings suggest that this treatment regimen may offer a potential therapeutic option for patients with gallbladder FDCS and liver metastases, with a duration of PR lasting up to 30 months.

Tumor-suppressive miR-4732-3p is sorted into fucosylated exosome by hnRNPK to avoid the inhibition of lung cancer progression.

BACKGROUND: Aberrant fucosylation observed in cancer cells contributes to an augmented release of fucosylated exosomes into the bloodstream, where miRNAs including miR-4732-3p hold promise as potential tumor biomarkers in our pilot study. However, the mechanisms underlying the sorting of miR-4732-3p into fucosylated exosomes during lung cancer progression remain poorly understood. METHODS: A fucose-captured strategy based on lentil lectin-magnetic beads was utilized to isolate fucosylated exosomes and evaluate the efficiency for capturing tumor-derived exosomes using nanoparticle tracking analysis (NTA). Fluorescence in situ hybridization (FISH) and qRT-PCR were performed to determine the levels of miR-4732-3p in non-small cell lung cancer (NSCLC) tissue samples. A co-culture system was established to assess the release of miRNA via exosomes from NSCLC cells. RNA immunoprecipitation (RIP) and miRNA pull-down were applied to validate the interaction between miR-4732-3p and heterogeneous nuclear ribonucleoprotein K (hnRNPK) protein. Cell functional assays, cell derived xenograft, dual-luciferase reporter experiments, and western blot were applied to examine the effects of miR-4732-3p on MFSD12 and its downstream signaling pathways, and the impact of hnRNPK in NSCLC. RESULTS: We enriched exosomes derived from NSCLC cells using the fucose-captured strategy and detected a significant upregulation of miR-4732-3p in fucosylated exosomes present in the serum, while its expression declined in NSCLC tissues. miR-4732-3p functioned as a tumor suppressor in NSCLC by targeting 3'UTR of MFSD12, thereby inhibiting AKT/p21 signaling pathway to induce cell cycle arrest in G2/M phase. NSCLC cells preferentially released miR-4732-3p via exosomes instead of retaining them intracellularly, which was facilitated by the interaction of miR-4732-3p with hnRNPK protein for selective sorting into fucosylated exosomes. Moreover, knockdown of hnRNPK suppressed NSCLC cell proliferation, with the elevated levels of miR-4732-3p in NSCLC tissues but the decreased expression in serum fucosylated exosomes. CONCLUSIONS: NSCLC cells escape suppressive effects of miR-4732-3p through hnRNPK-mediated sorting of them into fucosylated exosomes, thus supporting cell malignant properties and promoting NSCLC progression. Our study provides a promising biomarker for NSCLC and opens a novel avenue for NSCLC therapy by targeting hnRNPK to prevent the "exosome escape" of tumor-suppressive miR-4732-3p from NSCLC cells.

Genetic predisposition, modifiable lifestyles, and their joint effects on human lifespan: evidence from multiple cohort studies.

OBJECTIVE: To investigate the associations across genetic and lifestyle factors with lifespan. DESIGN: A longitudinal cohort study. SETTING: UK Biobank. PARTICIPANTS: 353 742 adults of European ancestry, who were recruited from 2006 to 2010 and were followed up until 2021. EXPOSURES: A polygenic risk score for lifespan with long (highest quintile) risk categories and a weighted healthy lifestyle score, including no current smoking, moderate alcohol consumption, regular physical activity, healthy body shape, adequate sleep duration, and a healthy diet, categorised into favourable, intermediate, and unfavourable lifestyles. MAIN OUTCOME MEASURES: Lifespan defined as the date of death or the censor date minus the date of birth. RESULTS: Of the included 353 742 participants of European ancestry with a median follow-up of 12.86 years, 24 239 death cases were identified. Participants were grouped into three genetically determined lifespan categories including long (20.1%), intermediate (60.1%), and short (19.8%), and into three lifestyle score categories including favourable (23.1%), intermediate (55.6%), and unfavourable (21.3%). The hazard ratio (HR) of death for individuals with a genetic predisposition to a short lifespan was 1.21 (95% CI 1.16 to 1.26) compared to those with a genetic predisposition to a long lifespan. The HR of death for individuals in the unfavourable lifestyle category was 1.78 (95% CI 1.71 to 1.85), compared with those in the favourable lifestyle category. Participants with a genetic predisposition to a short lifespan and an unfavourable lifestyle had 2.04 times (95% CI 1.87 to 2.22) higher rates of death compared with those with a genetic predisposition to a long lifespan and a favourable lifestyle. No multiplicative interaction was detected between the polygenic risk score of lifespan and the weighted healthy lifestyle score (p=0.10). The optimal combination of healthy lifestyles, including never smoking, regular physical activity, adequate sleep duration, and a healthy diet, was derived to decrease risk of premature death (death before 75 years). CONCLUSION: Genetic and lifestyle factors were independently associated with lifespan. Adherence to healthy lifestyles could largely attenuate the genetic risk of a shorter lifespan or premature death. The optimal combination of healthy lifestyles could convey better benefits for a longer lifespan, regardless of genetic background.

Illuminating the immunological landscape: mitochondrial gene defects in pancreatic cancer through a multiomics lens.

This comprehensive review delves into the complex interplay between mitochondrial gene defects and pancreatic cancer pathogenesis through a multiomics approach. By amalgamating data from genomic, transcriptomic, proteomic, and metabolomic studies, we dissected the mechanisms by which mitochondrial genetic variations dictate cancer progression. Emphasis has been placed on the roles of these genes in altering cellular metabolic processes, signal transduction pathways, and immune system interactions. We further explored how these findings could refine therapeutic interventions, with a particular focus on precision medicine applications. This analysis not only fills pivotal knowledge gaps about mitochondrial anomalies in pancreatic cancer but also paves the way for future investigations into personalized therapy options. This finding underscores the crucial nexus between mitochondrial genetics and oncological immunology, opening new avenues for targeted cancer treatment strategies.

TyG-GGT is a Reliable Non-Invasive Predictor of Advanced Liver Fibrosis in Overweight or Obese Individuals.

BACKGROUND: Liver fibrosis is a predisposing factor for liver cancer. This study will investigate the predictive role of the Triglyceride-glucose and Gamma-glutamyl transferase index (TyG-GGT) as a non-invasive indicator of advanced liver fibrosis in individuals with obesity or overweight. METHOD: We enrolled patients who underwent metabolic and bariatric surgery as well as intraoperative liver biopsies at Zhejiang provincial people's hospital from August 2020 to March 2023. Clinical characteristics, comorbidities, laboratory data, and pathological variables of patients were collected and analysed. Then, we conducted logistics regression model to compare the performance of the TyG-GGT index with other 4 non-invasive models. RESULTS: A total of 65 patients were included in this study. 43(66.2%) of them were female, with the mean body mass index (BMI) of 39.0 ± 7.3 kg/m2. Meanwhile, 24(36.9%) patients were diagnosed with diabetes. Advanced liver fibrosis were observed in 16.9% of patients, while liver cirrhosis was found in 4.6% of patients. The multivariable logistics regression showed that TyG-GGT was an independent risk factor of advanced liver fibrosis (OR = 6.989, P = 0.049). Additionally, compared to another 4 non-invasive liver fibrosis models (NFS = 0.66, FIB4 = 0.65, METS-IR = 0.68, APRI = 0.65), TyG-GGT exhibits the highest AUC value of 0.75. CONCLUSIONS: More than one-third of patients undergoing metabolic and bariatric surgery are afflicted with nonalcoholic steatohepatitis (NASH), and a significant proportion exhibit advanced fibrosis. TyG-GGT was a potentially reliable predictor for screening individuals with overweight or obesity at high risk of advanced liver fibrosis, thus providing clinical guidance for early intervention in this targeted group.

Three-dimensional finite element analysis on stress distribution after different palatoplasty and levator veli palatini muscle reconstruction.

OBJECTIVES: To establish a three-dimensional finite element model of the upper palate, pharyngeal cavity, and levator veli palatini muscle in patients with unilateral complete cleft palate, simulate two surgical procedures that the two-flap method and Furlow reverse double Z method, observe the stress distribution of the upper palate soft tissue and changes in pharyngeal cavity area after different surgical methods, and verify the accuracy of the model by reconstructing and measuring the levator veli palatini muscle. MATERIALS AND METHODS: Mimics, Geomagic, Ansys, and Hypermesh were applied to establish three-dimensional finite element models of the pharyngeal cavity, upper palate, and levator veli palatini muscle in patients with unilateral complete cleft palate. The parameters including length, angle, and cross-sectional area of the levator veli palatini muscle etc. were measured in Mimics, and two surgical procedures that two-flap method and Furlow reverse double Z method were simulated in Ansys, and the area of pharyngeal cavity was measured by hypermesh. RESULTS: A three-dimensional finite element model of the upper palate, pharyngeal cavity, and bilateral levator veli palatini muscle was established in patients with unilateral complete cleft palate ; The concept of horizontal projection characteristics of the palatal dome was applied to the finite element simulation of cleft palate surgery, vividly simulating the displacement and elastic stretching of the two flap method and Furlow reverse double Z method during the surgical process; The areas with the highest stress in the two-flap method and Furlow reverse double Z method both occur in the hard soft palate junction area; In resting state, as measured, the two flap method can narrow the pharyngeal cavity area by 50.9%, while the Furlow reverse double Z method can narrow the pharyngeal cavity area by 65.4%; The measurement results of the levator veli palatini muscle showed no significant difference compared to previous studies, confirming the accuracy of the model. CONCLUSIONS: The finite element method was used to establish a model to simulate the surgical procedure, which is effective and reliable. The area with the highest postoperative stress for both methods is the hard soft palate junction area, and the stress of the Furlow reverse double Z method is lower than that of the two-flap method. The anatomical conditions of pharyngeal cavity of Furlow reverse double Z method are better than that of two-flap method in the resting state. CLINICAL RELEVANCE: This article uses three-dimensional finite element method to simulate the commonly used two-flap method and Furlow reverse double Z method in clinical cleft palate surgery, and analyzes the stress distribution characteristics and changes in pharyngeal cavity area of the two surgical methods, in order to provide a theoretical basis for the surgeon to choose the surgical method and reduce the occurrence of complications.

The Effect of Central Sensitization on Postoperative Neurocognitive Dysfunction in Hospitalized Elderly Patients: A Prospective Cohort Clinical Trial.

OBJECTIVE: To investigate whether central sensitization (CS) in elderly patients was a predictive risk factor for postoperative neurocognitive dysfunction (PNCD). METHODS: One hundred and thirty-three aged patients undergoing total knee arthroplasty (TKA) who received femoral nerve block and general anesthesia were recruited in this research and prospectively assigned into two groups according to the Central Sensitization Inventory (CSI) score: group C (n = 106, CSI score less than 40) and group CS (n = 27, CSI score higher than 40). Scores of Montreal Cognitive Assessment (MoCA), Mini-Mental State Examination (MMSE), Confusion Assessment Method (CAM), Numerical Rating Scale (NRS) and Quality of recovery-40 (QoR-40) questionnaires were assessed. Basic information and clinical records of all participants were also collected. RESULTS: PNCD occurred in 24 (22.6%) of patients in group C and 16 (59.3%) in group CS (p < .05). Multivariate logistic regression analysis revealed that patients with CSI score ≥40 before surgery exhibited higher risk of PNCD after adjustment for other risk factors (p < .05). Compared to group C, the pre- and post-operative NRS scores, pain duration, the WOMAC score, and propofol consumptions for anesthesia induction were significantly increased in group CS (p < .05). CONCLUSION: Hospitalized elderly patients with clinical symptoms of CS scores may have increased risk of PNCD following TKA.

Observation of Serological Index and Efficacy of Abiraterone Hydrochloride Tablets Combined with Endocrine Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer.

PURPOSE: This study reviewed and analysed the serological indexes, clinical efficacy and common clinical indexes of patients with metastatic castration-resistant prostate cancer (mCRPC) treated with combination of abiraterone hydrochloride tablets and endocrine therapy. METHOD: This study is a retrospective analysis. A total of 133 mCRPC patients who were admitted to our hospital from January 2019 to December 2021 were selected as the study subjects. The patients were categorised into the experimental group (n = 51) and control group (n = 82) according to their treatment method. The control group was treated with docetaxel combined with endocrine therapy, whilst the experimental group was treated with combination therapy with abiraterone hydrochloride tablets. Subsequently, the clinical data of the two groups, including serum insulin-like growth factor-1 (IGF-1), human glandular kallikrein 2 (hK2), prostate specific antigen (PSA), vascular endothelial growth factor (VEGF) and serum carcinoembryonic antigen (CEA), were analysed. RESULT: The overall response rate of the experimental group (84.3%) was higher than that of the control group (72.0%). The serum levels of CEA, total prostate specific antigen, free prostate specific antigen, testosterone and androgen receptor splice variant 7 in both groups were lower than those of before treatment, and the values obtained by the experimental group were lower than those of the control group (p < 0.05). After treatment, the levels of CD3+, CD4+ and CD4+/CD8+ in both groups were higher than those before treatment, and the levels of CD8+, IGF-1, hK2, PSA and VEGF in the two groups decreased after treatment (p < 0.05). CONCLUSIONS: The use of abiraterone hydrochloride tablet combined with endocrine therapy for patients with mCRPC is effective and can improve clinical symptoms and serum cytokine levels.

Efficacy and safety of Simiao decoction in the treatment of cervical HPV infection: A systematic review and meta-analysis of randomized clinical trials.

Background: Persistent HPV infection can easily lead to the occurrence and development of cervical cancer and its precancerous lesions. Many studies have shown that Simiao Decoction may be effective in treating HPV infection, but the efficacy and safety of Simiao Decoction for HPV infection have never been systematically evaluated. Purpose: To evaluate the efficacy and safety of Simiao Decoction in the treatment of cervical HPV infection. Study design: A systematic review and meta-analysis of all randomized clinical trials (RCTs) comparing Simiao Decoction versus conventional treatment. Materials and methods: Seven databases were searched from their inception until May 14, 2023. All the RCTs comparing the efficacy and safety of Simiao Decoction versus conventional treatment were selected. Analyses were performed using Review Manager 5.3. HPV negative conversion rate (NCR) was defined as the primary endpoint, and treatment response rate (TRR), and adverse reaction (AR) were defined as the secondary endpoints. The quality of each endpoint was assessed by The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system. Results: Ten RCTs recruiting 799 patients with HPV infection were included. The results showed that compared with conventional treatment, Simiao Decoction improved NCR (RR = 1.45, 95 % CI 1.31, 1.61, P < 0.00001), TRR (RR = 1.24, 95%CI 1.15, 1.33, P < 0.000 01), while it did not increase AR (RR = 0.79, 95%CI 0.46, 1.33, P = 0.37). Most results were robust and the quality of evidence was moderate. Conclusion: Simiao Decoction is safer and more effective than conventional treatment for HPV infection. However, the efficacy and safety of Simiao Decoction should be further assessed by more high-quality RCTs with the outcome of HPV viral load and long-term follow-ups.

The EMT-Related Genes GALNT3 and OAS1 are Associated with Immune Cell Infiltration and Poor Prognosis in Lung Adenocarcinoma.

BACKGROUND: Lung cancer is the main cause of cancer-related death, with epithelial-mesenchymal transition (EMT) playing an important role in the development of this disease. The EMT-related genes Polypeptide N-Acetylgalactosaminyltransferase 3 (GALNT3) and 2'-5'-Oligoadenylate Synthetase 1 (OAS1) are involved in numerous tumor processes. Although these genes have been extensively studied in cancer, they have yet to be analyzed by multi-omics in lung adenocarcinoma (LUAD). METHODS: EMT-related genes were identified by R and Venn diagram. Cox regression and Kaplan-Meier analysis were performed to evaluate patient survival, and the Gene Expression Profiling Interactive Analysis (GEPIA) database was used for correlation analysis. GeneCards and R packages were used to explore gene characterization and functional annotation. The Tumor Immune Estimation Resource (TIMER), Human Protein Atlas (HPA), University of Alabama at Birmingham Cancer (UALCAN), and The Cancer Genome Atlas (TCGA) databases were used to investigate gene expression, which was then confirmed by RT-PCR. Clinicopathological analysis was carried out using the UALCAN database. Functional mechanisms and multi-omics analysis were performed using DNA Methylation Interactive Visualization Database (DNMIVD), Targetscan, TIMER, Tumor-immune System Interactions Database (TISIDB) and cBioportal. Diagnostic values were calculated using ROC curve analysis. RESULTS: A total of 320 EMT-related genes were identified in LUAD. Their characteristics were confirmed in the Database for Annotation, Visualization and Integrated Discovery (DAVID) database by the intersection of 855 and 3600 different genes from the Gene Expression Omnibus (GEO) and EMTome databases, respectively. Expression of the EMT-related genes GALNT3 and OAS1 was associated with the prognosis of LUAD patients. A positive correlation was observed between the expression of GALNT3 and OAS1, and their expression was higher in LUAD tissue than in normal lung tissue. This was confirmed using RT-PCR. Multi-omics analysis revealed that GALNT3 and OAS1 expression was associated with gene mutation and methylation, cellular immune infiltration, and several immune subtypes. A miRNA-GALNT3/OAS1 regulatory network was also found. Receiver operating characteristic (ROC) curve analysis found that GALNT3 and OAS1 expression combined had superior diagnostic value to that of each marker alone. CONCLUSIONS: GALNT3 and OAS1 expression are associated with immune cell infiltration and poor prognosis in LUAD. Their combined expression has high diagnostic value; hence, GALNT3 and OAS1 may be valuable biomarkers for the early detection of LUAD.
