Prognostic Value of Preoperative Controlling Nutritional Status in Hypopharyngeal Cancer Patients Undergoing Surgery-Oriented Comprehensive Treatment.

OBJECTIVES: The preoperative controlling nutritional status (pCONUT) score has been shown correlated with the prognosis of some cancerous diseases; however, little is known about the effect of pCONUT score on hypopharyngeal cancer (HPC). Therefore, the objective of our study was to demonstrate the relationship between the pCONUT score and the clinical outcome of patients with HPC. PATIENTS AND METHODS: Ninety-four patients with HPC who underwent surgery between May 2012 and Dec 2020 were enrolled in this study. We evaluated retrospectively their pCONUT scores and calculated the cutoff value regarding the patients' overall survival using the X-tile software. Kaplan-Meier and Cox proportional hazard regression model were used to determine how the pCONUT score affected overall survival. RESULTS: A cutoff level of 4 was determined to be optimal for the pCONUT score, by which the patients were grouped into high pCONUT score (≥4, n = 22, 23.4%) or low pCONUT score (<4, n = 72, 76.6%) groups. The univariate analysis showed that high pCONUT scores correlated with reduced overall survival (hazard ratio: 2.925, 95% confidence interval: 1.526-5.607, P = .001). Furthermore, the multivariate analysis also showed that high pCONUT scores increased the risk of overall death (hazard ratio: 2.639, 95% confidence interval: 1.365-5.101, P = .004). CONCLUSIONS: The pCONUT score is considered a useful prognostic factor in patients with HPC.

Review of antidepressants in clinic and active ingredients of traditional Chinese medicine targeting 5-HT1A receptors.

Serotonin, which also named as 5-hydroxytryptamine (5-HT), is a neurotransmitter, which plays significant roles in a wide range of physiological and pathological processes. Depression is a complex disease that involves numerous factors, increasing evidences have showed that the level of 5-HT was lower in depressed patients and the administration of some selective serotonin re-uptake inhibitors exhibited antidepressant effects. The 5-HT1A receptor is a key protein in the brain serotonin system, modulating the release of 5-HT and other neurotransmitters. Behavioral and molecular biological studies have demonstrated that the differences of 5-HT1A receptor regulation was connected with depression and the responses to antidepressants. In this review, the authors will introduce the structure and function of 5-HT1A receptor and summarize some antidepressants targeting 5-HT1A receptor, including 5-HT1A receptor agonists and antagonists in a clinic, active ingredients of traditional Chinese medicine. And we found the major of drugs by targeting 5-HT1A receptor on the market or in clinical trials mostly have the similar functional groups, such as piperazine, piperidine, and pyrimidine. There are also some literatures found that these functional groups may be the site produce activity. So, we hope that it may provide basis and references for the research of the clinical drugs for depression.

[Effective components of traditional Chinese medicine for regulating TGF-Beta1/Smads signaling pathway in hepatic fibrosis].

Hepatic fibrosis is a liver damage healing response affected by a variety of factors; its formation is associated with multiple cytokines and a variety of signaling pathways. Transforming growth factor beta1( TGF-ß1) is one of the strongest fibrosis cytokines known,and involves almost all the key links in hepatic fibrosis. TGF-ß1/Smads signal pathway is the most classical pathway for TGF-ß1 to play its role in promoting fibrosis as well as one of the most important signaling pathways of hepatic fibrosis formation. Studies for the signal pathway have made a series of scientific research achievements in recently years. Traditional Chinese medicine has the advantages of " multiple ingredients,multiple targets and less side effects",and is widely used in the clinical treatment of hepatic fibrosis.Effective components of traditional Chinese medicine are monomer compounds,which are extracted and purified from traditional Chinese medicine. Nowadays,the molecular biology studies of effective traditional Chinese medicine have become a hotspot. Modern advanced technology and methods can be used to directly clarify the targets and the signaling pathways,reveal the mechanism of traditional Chinese medicine in treating diseases,and promote the modernization and international development of traditional Chinese medicine industry. This review summarized the structure,function and application of TGF-ß1/Smads signaling pathway in the progress of anti-hepatic fibrosis,and analyzed the action mode and possible mechanism of various effective components of traditional Chinese medicine in regulating TGF-ß1/Smads signaling pathway and intervening the treatment of hepatic fibrosis in the past five years,so as to put forward new ideas for innovating new targeted traditional Chinese medicine for hepatic fibrosis.
