Expression, Prognostic Value, and Immune Infiltration of MTHFD Family in Bladder Cancer.

BACKGROUND: The Methylenetetrahydrofolate Dehydrogenase (MTHFD) family plays an important role in the development and prognosis of a variety of tumors; however, the role of the MTHFD family in bladder cancer is unclear. METHODS: R software, cBioPortal, GeneMANIA, and online sites such as String-LinkedOmics were used for bioinformatics analysis. RESULTS: MTHFD1/1L/2 was significantly upregulated in bladder cancer tissues compared with normal tissues, high expression of the MTHFD family was strongly associated with poorer clinical grading and staging, and bladder cancer patients with upregulated expression of MTHFD1L/2 had a significantly worse prognosis. Gene function and PPI network analysis revealed that the MTHFD family and related genes play synergistic roles in the development of bladder cancer. 800 co-expressed genes related to the MTHFD family were used for functional enrichment analysis, and the results showed that many genes were associated with various oncogenic pathways such as cell cycle and DNA replication. More importantly, the MTHFD family was closely associated with multiple infiltrating immune lymphocytes, including Treg cells, and immune molecules such as TNFSF9, CD274, and PDCD1. CONCLUSION: Our study shows that MTHFD family genes may be potential prognostic markers and therapeutic targets for patients with bladder cancer.

Incidence, Prognostic Factors, and Survival of Patients with Renal Cancer: A Population-Based Study.

BACKGROUND: The main objective of this article is to understand trends in the incidence of renal cancer and to construct a nomogram to predict the prognosis of patients with renal cancer by analyzing clinical parameters. METHODS: We extracted data from the Surveillance, Epidemiology and End Results (SEER) database for patients with renal cancer from 2010 to 2015. The incidence rate was calculated to understand the trend of renal cancer in recent years, and the Kaplan-Meier method was used to analyze the relationship between patients' clinical variables and overall survival. Nomogram and calibration curves were constructed based on factors predicted by multivariate Cox regression. RESULTS: Data from 68,496 eligible renal cancer patients were included in the study. The incidence of renal cancer was higher in men than women and tended to stabilize over time. We further found that age, gender, marital status, AJCC stage, histological type, metastatic disease, and surgery were independent parameters for prognosis in renal cancer patients. Finally, a nomogram was constructed based on the above parameters, and its validity was verified with the agreement index and calibration curve. CONCLUSION: Renal cancer incidence trend gradually stabilized. Seven independent parameters for renal cancer patients were obtained by analysis and utilized to construct a nomogram that could provide guidance for clinical practice.

Incidence, prognostic factors and survival in bladder cancer patients: a population-based study.

Background: The aim of this study was to investigate the incidence, epidemiologic characteristics, prognostic factors and survival of patients with bladder cancer. Methods: Bladder cancer patients diagnosed between 2010 and 2015 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate Cox proportional hazards regression analyses were used to identify the independent prognostic factors for overall survival. Kaplan-Meier survival analysis and nomogram analysis were constructed based on the identified independent prognostic factors. Results: A total of 95,329 eligible bladder cancer patients were included in this study. Eight independent risk factors, including age, histologic type, race, tumor, node and metastasis (TNM) stage, American Joint Committee on Cancer (AJCC) stage, surgery, tumor metastasis and summary stage, were recognized by using multivariate logistic regression models. By comprising these factors, a predictive nomogram was constructed to predict the 1-, 3-, and 5-year overall survival possibilities. The concordance index and calibration curve showed that the nomogram had robust and accurate performance. Conclusions: Bladder cancer is the most common cancer of the urinary system, but the overall incidence has been decreasing yearly since 1992. Our results demonstrate eight factors significantly associated with overall survival in bladder cancer patients. Based on these factors, we established and validated a nomogram, which has the potential to provide an individualized prediction of overall survival in patients with bladder cancer.

[Huanshao Capsules for oligoasthenospermia: A multicentered clinical trial].

Objective: To investigate the clinical efficacy and safety of Huanshao Capsules (HSC) in the treatment of oligoasthenospermia with spleen and kidney asthenia. METHODS: This randomized, open, multicentered, positive drug controlled clinical trial included 200 cases of oligoasthenospermia with spleen and kidney asthenia, which were assigned to a trial and a control group of equal number to be treated with HSC at the dose of 3 capsules tid and Wuziyanzong Pills at 6 g bid, respectively, both for 12 weeks. We compared the semen volume, sperm concentration, sperm count, sperm motility and percentage of progressively motile sperm (PMS) as the main therapeutic indicators as well as the pregnancy rate as the secondary therapeutic indicator between the two groups of patients before and at 4, 8 and 12 weeks after medication. RESULTS: Totally, 190 of the patients completed the clinical observation, 96 in the trial and 94 in the control group. Compared with the baseline, the patients of the trial group showed significant time-dependent increases at 4, 8 and 12 weeks after medication in the mean sperm concentration (14.78 vs 15.33, 20.98 and 28.78 ×106/ml, P < 0.05), percentage of grade a sperm (12.17% vs 15.05%, 21.17% and 26.97%, P < 0.05), PMS (24.78% vs 28.97%, 37.23% and 47.67%, P < 0.05), and sperm viability (38.64% vs 44.18%, 51.67% and 60.45%, P < 0.05). The pregnancy rate was significantly higher in the trial than in the control group 29.17% vs 18.09%, P < 0.05). CONCLUSIONS: Huanshao Capsules can improve the semen quality and pregnancy rate in the treatment of oligoasthenospermia patients with spleen and kidney asthenia, and therefore deserves a wide clinical application.
