ObjectiveTo elucidate the mechanism of evolimus (EVR) and its application, efficacy and common adverse reactions in hepatocellular carcinoma (HCC) patients after liver transplantation.MethodRelevant literatures in recent years were searched through websites such as Wanfang, CNKI and PubMed, and the results were read, analyzed and summarized.ResultsCurrently, there are a wide variety of immunosuppressive agents for HCC patients after liver transplantation, and immunosuppressive treatment options are also diverse and there is no unified standard. Today is more widely used clinically used for transplantation immune inhibitors of calcineurin inhibitors (CNIs), but because of its renal toxicity and side effects and recurrence of HCC risk increases, CNIs in HCC patients after liver transplantation using gradually is restricted, and mammalian target of rapamycin (mTOR) inhibitors are valued, gradually into clinical immunosuppression after liver transplantation for treatment provides a new way of thinking. As an mTOR inhibitor, EVR is gradually being applied to HCC patients after liver transplantation.ConclusionAs an mTOR inhibitor only approved for use in HCC patients after liver transplantation in recent years, relevant literature studies have shown that EVR plays an important role in improving the success rate of transplantation, protecting renal function and inhibiting HCC recurrence.
ObjectiveTo summarize the characteristics of hexosamine biosynthesis pathway (HBP) and O-glycosylation and their roles in metabolism of hepatocellular carcinoma. MethodTo review the current literatures on the role of HBP and O-glycosylation in tumors, especially in hepatocellular carcinoma. ResultsThere was metabolic reprogramming in hepatocellular carcinoma cells, and the HBP was a branch of glycolysis pathway, which played an important role in tumorigenesis, development, and metastasis. HBP provided uridine diphosphate-N-acetylglucosamine (UDP-GlcNAc) for O-glycosylation, UDP-GlcNAc was a substrate for OGT, participating in O-glycosylation. O-glycosylation was a type of posttranslational modification that regulates the biological behavior of tumor cells by glycosylation of target proteins in tumor cells. ConclusionHBP and O-glycosylation can be used as intervention targets in the treatment of hepatocellular carcinoma, which provides a potential method for scientific prevention and treatment of hepatocellular carcinoma.
ObjectiveTo summarize the research progress of the pathogenesis, diagnosis and treatment of sarcopenia in liver cirrhosis. MethodThe relevant literatures on studies of the pathogenesis, diagnosis and treatment of sarcopenia in liver cirrhosis in recent years were searched and reviewed. ResultsThe sarcopenia was a major complication that could not be ignored in patients with liver cirrhosis, and was closely related to the patient’s quality of life and prognosis. Various mechanisms such as metabolic abnormalities, malnutrition, myostatin, hyperammonemia, hormonal regulation of muscle homeostasis, ubiquitin-proteasome system and autophagy, physical activity, and dysbiosis of the intestinal flora were involved in the development of sarcopenia. There were various diagnostic methods for sarcopenia, but a unified gold standard was still lacking. In addition, some progress had been made in the treatment of sarcopenia in recent years. ConclusionsAlthough current studies obtains preliminary results about relation between liver cirrhosis and sarcopenia, there still exists many problems to be solved. Further research in future will benefit diagnosis and treatment of patients with sarcopenia in liver cirrhosis.
Objective To investigate the effects of cimetidine on the red cell immune function and interleukin-2(IL-2) in rats with obstructive jaundice. Methods Sixty SD rats were divided into bile duct ligation(BDL) group, cimetidine therapy (BDLC) group and sham operation(SO) group respectively. The red cell immue function and serum IL-2 level were determined with the red cell yeast-rosttes test and radioimmunoassay respectively. Results The red blood cell C3b receptor rosette rate(RBC-C3bRR), the red blood cell immune complex rosette rate(RICR), the red blood cell C3b receptor rosette-forming excited rate(RFER) and serum IL-2 level were significantly lower in BDL group as compared with SO group, the red blood cell C3b receptor rosette-forming inhibitory rate(RFIR) in BDL group was higher than that of SO group. After 7 days’ cimetidine therapy RBCC3bRR, RICR, RFER and IL-2 became higher than those of BDL group, but RFIR was lower than that of BDL group. Conclusion Supplemental cimetidine can significantly enhance the impaired red cell immune function and IL-2 production in rats with obstructive jaundice.
Objective To assess the efficacy and safety of acupuncture for patients with hiccups after stroke. Methods The randomized controlled trials (RCTs) of acupuncture for patients with hiccups after stroke were collected by searching PubMed, The Cochrane Library, CNKI, VIP, and WangFang databases. The quality of the included studies was evaluated and the data were retrieved according to the methods recommended by the Cochrane Collaboration. Meta-analyses were conducted by using RevMan software. Results Three trials involving 143 patients were included. All of them were open-label controlled without observing the effective rate and mortality rate (or dependence rate) at the end of follow-up visit lasting for at least three months. The result of meta-analyses showed that the group of acupuncture plus drug was more effective for hiccup after stroke than the drug group at the end of the treatment, and the difference was significant (OR=9.05, 95%CI 3.17 to 25.82, Plt;0.000 01). The three studies did not report any adverse reactions. Conclusion Although the acupuncture has the short-term improvement trend without adverse events for hiccups after stroke, the confirmed conclusion of long-term effectiveness has not yet been reached because both the methodological quality and the quantity of all included studies are poor, and especially the long-term outcome measures are insufficient. There is no enough evidence to recommend acupuncture as a routine treatment for hiccups after stroke. So more high-quality multi-center RCTs in large scale are required.
ObjectiveTo summarize progress of immune response in severe acute pancreatitis (SAP) and to provide a basis for appropriate immunotheraphy.MethodThe relevant literatures about the effect of immune response in the SAP with infectious complications in recent years were reviewed.ResultsThe inflammatory cascade reaction occurred in the early stage of SAP. Subsequently, the compensatory anti-inflammatory response syndrome (CARS) arised and immune response of the organism was suppressed. At this stage, the rate of infection was higher than before.ConclusionsCARS is one of major reasons in SAP with infectious complications. At present, fluid infusion, fasting, parenteral nutrition and like are major therapies in SAP. If corresponding immunotherapy could be carried out according to immune mechanism of SAP infection, that is, early appropriate immunosuppressive therapy and dynamic monitoring of body’s immune system state should be performed, when it is found that immunosuppression is present, appropriate immunostimulus therapy will be possible to reduce mortality of SAP and improve its prognosis.
ObjectiveTo summarize the research progress of diagnosis and treatment in hypertriglyceridemia pancreatitis in recent years.MethodsThrough the retrieval of relevant literatures, the progress of diagnosis and treatment in hypertriglyceridemia pancreatitis were reviewed.ResultsHypertriglyceridemia pancreatitis is a rare acute pancreatitis, but with the improvement of living standard and the change of diet structure, the incidence of this disease in recent years was increasing, and more likely to lead to complications, causing serious consequences. The treatment of hypertriglyceridemia pancreatitis in addition to the routine treatment of pancreatitis, attention should also be paid to the rapid reduction of blood triglyceride levels, including plasma exchange, the use of low molecular weight heparin and insulin, and the use of lipid-lowering drugs.ConclusionsHypertriglyceridemia pancreatitis is more severe than acute pancreatitis caused by other causes, and the incidence of complications is higher. Maintaining a lower level of blood triglycerides is of great significance for the improvement of this pancreatitis and the prevention of the recurrence of pancreatitis.
ObjectiveTo explore the immune biomarkers for prognosis of breast cancer and to construct a risk assessment model.MethodsThe gene expression of breast cancer samples was retrieved from The Cancer Genome Map (TCGA) database and immune related genes (IRGs) were retrieved from the ImmPort database. Cox proportional hazards regression and least absolute shrinkage and selection operator (LASSO) regression were used for prognostic analysis. Gene set enrichment analysis ( GSEA) was used to explore biological signaling pathways. ESTIMATE and CIBERSORT algorithms were used to explore the relationship between risk score and tumor immune microenvironment.ResultsNine kinds of immune-related differentially expressed genes independently related to prognosis were identified: adrenoceptor beta 1 (ADRB1), interleukin 12B (IL12B), syndecan 1 (SDC1), thymic stromal lymphopoietin (TSLP), fibroblast growth factor 19 (FGF19), fatty acid binding protein 7 (FABP7), interferon epsilon (IFNE), tumor necrosis factor receptor superfamily member 18 (TNFRSF18) and interleukin 27 (IL27). The risk assessment equation constructed by these nine kinds of genes had powerful predictive ability. The “neurotrophin signaling pathway” and “adipocyte factor signaling pathway” were activated in patients of high-risk group, and “leukocyte transendothelial migration” “WNT signaling pathway” “FcεRI signaling pathway” “valine, leucine and isoleucine biosynthesis” and “protein export pathway” were activated in patients of low-risk group. A variety of tumor-killing immune cells were significantly enriched in the tumor-infiltrating immune cells of patients in the low-risk group. The immunosuppressive immune cells were significantly enriched in tumor infiltrating immune cells of patients in high-risk group.ConclusionIRGs prognostic signatures are an effective potential predictive classifier in breast cancer treatment.
