There is a bidirectional association between tumor-associated macrophage (TAM) and colorectal cancer. Small molecular substances metabolized by colorectal cancer affect the reprogramming of TAM, and TAM in turn regulates the biological behavior of colorectal cancer cells by secreting small molecular substances, and promotes the progression of colorectal cancer. In addition, gut microbiota metabolites are closely related to TAM reprogramming, and intestinal flora imbalance leads to gut barrier damage, favoring bacterial translocation and causing chronic tumorigenic inflammation. Studying the reprogramming mechanism affecting TAM and its relationship with the occurrence and development of colorectal cancer may provide new ideas for the study of immunotherapy in patients with colorectal cancer. This article reviews the research progress of TAM in patients with colorectal cancer, aims to provide a reference for clinical research.
ObjectiveTo summarize the research progress of hydrogels for the regeneration and repair of degenerative intervertebral disc and to investigate the potential of hydrogels in clinical application.MethodsThe related literature about the role of hydrogels in intervertebral disc degeneration especially for nucleus pulposus was reviewed and analyzed.ResultsHydrogels share similar properties with nucleus pulposus, and it plays an important role in the regeneration and repair of degenerative intervertebral disc, which can be mainly applied in nucleus pulposus prosthesis, hydrogel-based cell therapy, non-cellular therapy, and tissue engineering repair.ConclusionHydrogels are widely used in the regeneration and repair of intervertebral disc, which provides a potential treatment for intervertebral disc degeneration.
ObjectiveTo analyze the trend of chronic kidney disease (CKD) disease burden attributable to metabolic factors in China from 1990 to 2021, and to predict the death of CKD due to metabolic factors in China from 2022 to 2046. MethodsBased on the 2021 Global Burden of Disease Database, this paper collected and sorted out the CKD deaths, disability-adjusted life years (DALYs), premature death lost life years (YLLs), and disability life lost years (YLDs) attributed to metabolic factors by different ages and sexes in China from 1990 to 2021, and used the Joinpoint regression model to systematically evaluate the temporal trends of standardized mortality and standardized DALYs rate. The age-period-cohort (APC) model was used to assess age, period, and cohort effects, and the R software Nordpred package was used to predict future changes in the burden of disease. ResultsCompared with 1990, the mortality rate, DALYs rate, YLLs rate, and YLDs rate attributable to metabolic factors of Chinese residents in 2021 showed an upward trend, and the characteristics of male higher than female, higher age group than lower age group. The primary metabolic factor influencing the disease burden of CKD is hyperglycemia. The results of Joinpoint analysis showed a downward trend in the standardized mortality and standardized DALYs rate of CKD attributed to metabolic factors. The results of age-period-cohort model analysis showed that the age effect of CKD attributed to metabolic factors increased significantly, the period effect increased slowly, and the cohort effect showed a downward trend. ConclusionThe disease burden of CKD attributed to metabolic factors in China is generally on the rise, and men, the elderly, and diabetic patients are the key focus of the disease.
ObjectivesTo systematically review the efficacy and safety of laparoscopic pyelolithotomy (LP) versus percutaneous nephrolithotomy (PNL) in treating large (>2 cm) renal pelvic calculi.MethodsDatabases including PubMed, EMbase, Web of Science, The Cochrane Library, CBM, CNKI and WanFang Data were searched for relevant randomized controlled trials (RCTs) comparing LP with PNL for the treatment of large renal pelvic calculi from inception to September 23th, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of eligible studies. Meta-analysis was then performed by using RevMan 5.2 software.ResultsFive RCTs with 447 patients were included. The results of meta-analysis showed that: compared with PNL group, LP group provided a significantly higher stone-free rate (RR=1.07, 95%CI 1.01 to 1.13, P=0.01), lower auxiliary procedure rate (RR=0.36, 95%CI 0.13 to 1.01, P=0.05), less hemoglobin decrease (MD=–0.83, 95%CI –1.05 to –0.61, P<0.000 01) and lower postoperative fever rate (RR=0.36, 95%CI 0.18 to 0.72,P=0.004). However, no significant differences were detected in conversion rate (RR=0.76, 95%CI 0.19 to 3.07, P=0.70), blood transfusion rate (RR=0.40, 95%CI 0.14, to 1.12, P=0.08), postoperative leakage rate (RR=1.87, 95%CI 0.67 to 5.21, P=0.23), operative time (MD=10.49, 95%CI –17.14 to 38.13, P=0.46) and hospital stay (MD=0.53, 95%CI –0.22 to 1.28, P=0.17).ConclusionsLP is superior to PNL with regard to stone-free rate, auxiliary procedure rate, hemoglobin decrease and postoperative fever rate. Due to limited quality and quantity of included studies, more high quality studies are required to verify above conclusions.
