L-carnitine combined with traditional Chinese medicine for male infertility: A systematic review and meta-analysis.

Background: Fertility rates are declining globally, and male infertility is increasingly recognized as a significant challenge. This study aims to present the latest findings on the effectiveness and safety of combining traditional Chinese medicine (TCM) with L-carnitine (LC) for treating male infertility. Methods: We searched 8 databases. Randomized controlled trials of TCM combined with LC therapy versus LC alone in the treatment of male infertility. The outcome included: pregnancy rate, sperm motility, concentration, volume, viability and liquefaction time. Subgroup analyses were also performed according to type of TCM, type of dosage form, and different TCM treatments, and the source of the high heterogeneity was explored. The study is registered on PROSPERO (CRD42023421497). Results: 1129 subjects from 12 of the 1833 eligible studies fulfilled the criteria. Compared with LC treatment alone, the combination of TCM and LC significantly improved pregnancy rate [RR = 1.65, 95 % CI (1.37-2.00)], grade (a+b) sperm motility [SMD = 1.56, 95 % CI (1.12, 2.01)], grade (a) sperm motility [SMD = 1.04, 95 % CI (0.69, 1.38)], sperm concentration [SMD = 1.39, 95 % CI (0.91, 1.86)], and sperm viability [SMD = 1.72, 95 % CI (0.83, 2.60)]. Subgroup analyses indicated that Compound Xuanju Capsule and Yougui Capsule demonstrated better efficacy. And the decoction and not-decoction each had their own advantages. Conclusions: The combination of TCM with LC can have a dual effect: increasing pregnancy rates and sperm quality. Therefore, this combination is a recommended therapeutic strategy and a more appropriate type of TCM can be selected according to the patient's own characteristics.

Decoding dynamic visual scenes across the brain hierarchy.

Understanding the computational mechanisms that underlie the encoding and decoding of environmental stimuli is a crucial investigation in neuroscience. Central to this pursuit is the exploration of how the brain represents visual information across its hierarchical architecture. A prominent challenge resides in discerning the neural underpinnings of the processing of dynamic natural visual scenes. Although considerable research efforts have been made to characterize individual components of the visual pathway, a systematic understanding of the distinctive neural coding associated with visual stimuli, as they traverse this hierarchical landscape, remains elusive. In this study, we leverage the comprehensive Allen Visual Coding-Neuropixels dataset and utilize the capabilities of deep learning neural network models to study neural coding in response to dynamic natural visual scenes across an expansive array of brain regions. Our study reveals that our decoding model adeptly deciphers visual scenes from neural spiking patterns exhibited within each distinct brain area. A compelling observation arises from the comparative analysis of decoding performances, which manifests as a notable encoding proficiency within the visual cortex and subcortical nuclei, in contrast to a relatively reduced encoding activity within hippocampal neurons. Strikingly, our results unveil a robust correlation between our decoding metrics and well-established anatomical and functional hierarchy indexes. These findings corroborate existing knowledge in visual coding related to artificial visual stimuli and illuminate the functional role of these deeper brain regions using dynamic stimuli. Consequently, our results suggest a novel perspective on the utility of decoding neural network models as a metric for quantifying the encoding quality of dynamic natural visual scenes represented by neural responses, thereby advancing our comprehension of visual coding within the complex hierarchy of the brain.

Visual identification of three kinds of human decidual tissues from elective termination of pregnancy.

INTRODUCTION: The decidua can be classified into the decidua basalis, decidua capsularis and decidua parietalis. This study aimed to visually identify these three kinds of decidual tissues from fresh samples obtained in early pregnancy based on their macroscopic appearances, which can be discerned visually. METHODS: Decidual samples were collected from 15 pregnant women between 6 and 8 weeks of gestation after elective termination of pregnancy. We identified the three different kinds of fresh decidual tissues in early pregnancy according to their different macroscopic appearances by only the naked eye. H&E staining, in situ immunofluorescence and flow cytometry were performed to confirm the accuracy of this method. RESULTS: We developed a method to discern the three different kinds of decidual tissues according to their individual macroscopic features. We found that the decidua parietalis was a thick tissue with less blood, with one side being intact epidermis and the other side being rough tissue. The decidua basalis had rough surfaces, a dense texture and high blood content. The decidua capsularis was a thin membrane tissue with or without blood clots. CK+/HLA-G+ extravillous trophoblast cells (EVTs) and heme oxygenase-1+ (HMOX1+) decidual macrophages were present in large quantities in the decidua basalis and decidua capsularis but were nearly undetectable in the decidua parietalis. We also found a wide distribution of endovascular extravillous trophoblast cells (enEVTs), which participate in spiral artery remodelling in the decidua basalis. DISCUSSION: We successfully identified three kinds of human decidual tissues from early pregnancy with the naked eye for the first time. This breakthrough method will greatly assist studies related to decidua during early pregnancy.

Efficacy and safety comparison between Lenvatinib and Sorafenib in hepatocellular carcinoma treatment: a systematic review and meta-analysis of real-world study.

OBJECTIVE: Our study aimed to evaluate the efficacy and safety of Lenvatinib compared with Sorafenib for treating hepatocellular carcinoma (HCC) patients under real-world setting. METHODS: We retrieved relevant literature through the PubMed, Embase, Web of Science, and Cochrane Library databases from 1 January 2000 to 25 June 2022. The differences in overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR) as well as treatment adverse related events were evaluated between HCC patients treated with Lenvatinib and Sorafenib using fixed or random-effects models. The MINORS evaluation questionnaire was used to assess the quality of the included literature. RESULTS: This meta-analysis included a total of 9 single-arm studies and 6 comparative studies. In the meta-analysis, Lenvatinib showed significantly longer median OS than Sorafenib ( P  < 0.01, MD = 1.20, 95% CI [0.92-1.48]), as well as median PFS ( P  < 0.01, OR = 2.68, 95% CI [1.59-3.76]), and higher ORR( P  < 0.01, OR = 5.36, 95% CI [3.42-8.40]), DCR( P  < 0.01, OR = 2.17, 95% CI [1.64-2.86]). The occurrence of Hypertension was higher in Lenvatinib than in Sorafenib treatment ( P  < 0.01, MD = 5.27, 95% CI [2.38-11.66]), and there was no significant difference in Hand-foot syndrome between Lenvatinib and Sorafenib. CONCLUSION: We found that treatment with Lenvatinib in HCC patients resulted in better OS, PFS, and higher ORR and DCR compared to Sorafenib. However, safety data indicated that Lenvatinib did not exhibit a significant advantage.

Associations between systemic immunity-inflammation index and heart failure: Evidence from the NHANES 1999-2018.

BACKGROUND: Heart failure (HF) is a disease closely associated with inflammation, and the systemic immune-inflammation index (SII) is a novel inflammatory marker. Therefore, this study aims to explore the relationship between SII and HF. METHODS: We used National Health and Nutrition Examination Survey data from 1998 to 2018 to include adults who reported a diagnosis of HF and complete information on the calculation of SII. SII was calculated as platelet count × neutrophil count/lymphocyte count. We used multiple logistic regression models to examine the association between SII and HF and explored possible influencing factors by subgroup analysis. In addition, we performed smoothed curve fitting and threshold effect analysis to describe the nonlinear relationship. RESULTS: The population-based study involved a total of 48,155 adults ages 20-85. Multivariate logistic regression showed that participants with the highest SII had a statistically significant 32% increased risk of HF prevalence compared to those with the lowest SII (OR = 1.32; 95% CI, 1.06-1.65, P = 0.0144) in a fully adjusted model. Subgroup analysis revealed no significant interactions between SII and specific subgroups (p > 0.05 for all interactions). Furthermore, the association between SII and HF was non-linear; the inflection point was 1104.78 (1000 cells/µl). CONCLUSIONS: Based on our findings, elevated SII levels were found to be strongly associated with the risk of HF, and SII was nonlinearly associated with HF. To validate these findings, a larger prospective investigation is needed to support the results of this study and investigate potential problems.

Association of per- and polyfluoroalkyl substance exposure with metabolic syndrome and its components in adults and adolescents.

Per- and polyfluoroalkyl substances (PFAS) are widespread contaminants, but few studies have explored the relationship between PFAS and levels of metabolic syndrome (MetS) in the population. The available evidence of an association is also conflicting. We selected adults and adolescents with complete PFAS data from the National Health and Nutrition Examination Survey conducted between 2003 and 2018. We analyzed the association between PFAS and MetS using multivariate logistic regression models and evaluated potential nonlinear relationships with restricted cubic spline models. Additionally, we employed weighted quantile sum (WQS) regressions to uncover the multiple exposure effects and relative weights of each PFAS. Finally, we conducted a series of sensitivity analyses to test the robustness of our findings. In this population-based study, we analyzed data from a total of 4,973 adults, aged 20-85 years, and 1,381 adolescents, aged 12-19 years. Using fully adjusted multivariate logistic regression models, we found that serum levels of perfluorodecanoate (PFDA) [0.65 (0.50, 0.85)] and total PFAS [0.92 (0.85, 0.99)] were negatively associated with the prevalence of MetS in adults. Similarly, in adolescents, we observed negative correlations between the prevalence of MetS and levels of PFDA [0.55 (0.38, 0.80)], perfluorooctanoic acid (PFOA) [0.62 (0.39, 1.00)], perfluorooctane sulfonic acid (PFOS) [0.59 (0.36, 0.96)], and total PFAS [0.61 (0.37, 0.99)]. Additionally, our study identified statistically significant negative associations between serum levels of PFAS and certain components of MetS, primarily elevated fasting glucose and lower high-density lipoprotein cholesterol. Our study found that PFAS was associated with a lower prevalence of MetS in both adults and adolescents, offering new insights into the relationship between PFAS and metabolic health. Interestingly, however, we observed conflicting findings across the components of MetS. Specifically, we observed that PFAS had a negative correlation with some metrics and a positive correlation with others. These conflicting results point to a complex interplay between PFAS and various metrics of metabolic health.

High Expression of FOXO3 in Gastric Cancer Tissues is Associated with Poor Prognosis and Immune Cell Infiltration.

BACKGROUND: The purpose of this study was to explore the role of FOXO3 in gastric cancer (GC). METHODS: Data on gastric cancer and normal tissues were collected from the TCGA and GTEx databases. Survival analysis was performed with the Kaplan-Meier method, and the ENCORI online analysis tool was used to predict potential interaction miRNA. The MCPCOUNTER and Tumor Immune Dysfunction and Exclusion (TIDE) algorithm were used to predict the relationship between immune infiltration and FOXO3. Finally, gene set enrichment analysis (GSEA) was used to explore the potential pathways of FOXO3 during the development of GC. RESULTS: We found that mRNA expression level of FOXO3 was remarkably higher in tumor tissue than in normal tissue, and poor prognoses of GC patients were correlated with higher expression of FOXO3. We also found that hsa-miR-18a-5p and hsa-miR-18b-5p can interact with FOXO3 and that high expression of hsa-miR-18a-5p and hsa-miR-18b-5p predicted better prognoses in GC patients. TP53 mutation was significantly associated with high FOXO3 expression, while ARID1A mutation was associated with low FOXO3 expression. Multiple immune cells were found to be related to the expression of FOXO3, and lower expression of FOXO3 may be better suited to immune checkpoint blockade treatment. CONCLUSIONS: We find that FOXO3 is a potential oncogene and that the transcript level of FOXO3 is related to the mutation of TP53 and ARID1A. In addition, FOXO3 may influence immune infiltration and different signal pathways through sponge adsorption of miRNA to impact the prognoses of stomach adenocarcinoma patients.

Integrated network pharmacology and metabolomics to dissect the mechanisms of naringin for treating cervical cancer.

INTRODUCTION: Cervical cancer is one of the malignant cancers with high mortality among women worldwide. Although vaccines and early detection have reduced cervical cancer mortality, it remains a malignancy with a high mortality rate in women. OBJECTIVE: We aimed to develop a novel integrated strategy that combines metabolomics with network pharmacology to explore the therapeutic mechanisms of naringin in cervical cancer. The mechanism of naringin intervention in cervical cancer was initially clarified by metabolomics and network pharmacology. METHODS: The method of LC-MS and network pharmacology for the detection and identification of potential biomarkers and the mechanisms of action of naringin was used. The metabolites were detected and identified based on ultra-high-performance liquid chromatography coupled with Quadrupole-Exactive Orbitrap MS (UHPLC-Q-Exactive Orbitrap MS) and followed by the network pharmacology analysis. RESULTS: In network pharmacology, naringin played a synergetic role through regulatory shared pathways, such as steroid hormone biosynthesis, sphingolipid signaling pathway and arachidonic acid metabolism, etc. Besides, the metabolomics analysis showed that 20 differential metabolites and 10 metabolic pathways were mainly involved in the therapeutic effect of naringin on cervical cancer. The result showed that naringin treatment for cervical cancer mainly occurs through the following metabolic pathways: amino acid metabolism and arachidonic acid metabolism. CONCLUSION: This work provided valuable information and a scientific basis for further studies of naringin in the treatment of cervical cancer.
