Clinical implications of forkhead box M1, cyclooxygenase-2, and glucose-regulated protein 78 in breast invasive ductal carcinoma

BACKGROUND Breast infiltrating ductal carcinoma(BIDC)represents the largest heterotypic tumor group,and an in-depth understanding of the pathogenesis of BIDC is key to improving its prognosis.AIM To analyze the expression profiles and clinical implications of forkhead box M1(FOXM1),cyclooxygenase-2(COX-2),and glucose-regulated protein 78(GRP78)in BIDC.METHODS A total of 65 BIDC patients and 70 healthy controls who presented to our hospital between August 2019 and May 2021 were selected for analysis.The peripheral blood FOXM1,COX-2,and GRP78 levels in both groups were measured and the association between their expression profiles in BIDC was examined.Additionally,we investigated the diagnostic value of FOXM1,COX-2,and GRP78 in patients with BIDC and their correlations with clinicopathological features.Furthermore,BIDC patients were followed for 1 year to identify factors influencing patient prognosis.RESULTS The levels of FOXM1,COX-2,and GRP78 were significantly higher in BIDC patients compared to healthy controls(P<0.05),and a positive correlation was observed among them(P<0.05).Receiver operating characteristic analysis demonstrated that FOXM1,COX-2,and GRP78 had excellent diagnostic value in predicting the occurrence of BIDC(P<0.05).Subsequently,we found significant differences in FOXM1,COX-2,and GRP78 levels among patients with different histological grades and metastasis statuses(with vs without)(P<0.05).Cox analysis revealed that FOXM1,COX-2,GRP78,increased histological grade,and the presence of tumor metastasis were independent risk factors for prognostic death in BIDC(P<0.001).CONCLUSION FOXM1,COX-2,and GRP78 exhibit abnormally high expression in BIDC,promoting malignant tumor development and closely correlating with prognosis.These findings hold significant research implications for the future diagnosis and treatment of BIDC.

Clinical implications of diabetes in chronic liver disease:Diagnosis,outcomes and management,current and future perspectives

Diabetes mellitus(DM)is common in liver cirrhosis(LC).The pathophysiological association is bidirectional.DM is a risk factor of LC and LC is a diabetogenic condition.In the recent years,research on different aspects of the association DM and LC has been intensified.Nevertheless,it has been insufficient and still exist many gaps.The aims of this review are:(1)To discuss the latest understandings of the association of DM and LC in order to identify the strategies of early diagnosis;(2)To evaluate the impact of DM on outcomes of LC patients;and(3)To select the most adequate management benefiting the two conditions.Literature searches were conducted using Pub Med,Ovid and Scopus engines for DM and LC,diagnosis,outcomes and management.The authors also provided insight from their own published experience.Based on the published studies,two types of DM associated with LC have emerged:Type 2 DM(T2 DM)and hepatogenous diabetes(HD).High-quality evidences have determined that T2 DM or HD significantly increase complications and death pre and post-liver transplantation.HD has been poorly studied and has not been recognized as a complication of LC.The management of DM in LC patients continues to be difficult and should be based on drug pharmacokinetics and the degree of liver failure.In conclusion,the clinical impact of DM in outcomes of LC patients has been the most studied item recently.Nevertheless many gaps still exist particularly in the management.These most important gaps were highlighted in order to propose future lines for research.

Atypical variants of takotsubo cardiomyopathy: mechanistic and clinical implications

Over past decades,takotsubo cardiomyopathy(TTC)has drawn a substantial interest as a unique form of acute and reversible cardiomyopathy that usually emerges in response to adrenergic hyperactivation associated with a variety of emotional and physical triggers.[1,2]Even though,this phenomenon is generally characterized by an apical balloning pattern(classical variant),it might occasionally present with atypical morphological variants including mid-ventricular,inverted and focal forms of myocardial involvement.

Detection of circulating tumour cells in colorectal cancer:Emerging techniques and clinical implications

Despite several advances in oncological management of colorectal cancer,morbidity and mortality are still high and devastating.The diagnostic evaluation by endoscopy is cumbersome,which is uncomfortable to many.Because of the intra-and inter-tumour heterogeneity and changing tumour dynamics,which is continuous in nature,the diagnostic biopsy and assessment of the pathological sample are difficult and also not adequate.Late manifestation of the disease and delayed diagnosis may lead to relapse or metastases.One of the keys to improving the outcome is early detection of cancer,ease of technology to detect with uniformity,and its therapeutic implications,which are yet to come."Liquid biopsy"is currently the most recent area of interest in oncology,which may provide important tools regarding the characterization of the primary tumour and its metastasis as cancer cells shed into the bloodstream even at the early stages of the disease.By using this approach,clinicians may be able to find out information about the tumour at a given time.Any of the following three types of sampling of biological material can be used in the"liquid biopsy".These are circulating tumour cells(CTCs),circulating tumour DNA,and exosomes.The most commonly studied amongst the three is CTCs.CTCs with their different applications and prognostic value has been found useful in colorectal cancer detection and therapeutics.In this review,we will discuss various markers for CTCs,the core tools/techniques for detection,and also important findings of clinical studies in colorectal cancer and its clinical implications.

DETERMINATION OF SERUM HARRINGTONINE IN PATIENTS WITH ANLL AND ITS CLINICAL IMPLICATION

Harringtonine(H) level in serum was quantified by high-performance liquid chromatographic (HPLC) technique and its pharmacokinetic parameters were determined in 11 patients with ANLL after 4 hours continuous infusion of 4 mg of H. 74 serum samples over the range of H administered 1-6 mg/d were also determined, the dose of H administered paralleled the mean serum H concentration, but the highest concentration were 1.6-7 folds higher than the lowest under the same doses. It seems that the dosage of harringtonine must be individualized in order to achieve better antileukemia effect. It was found that under the similar serum H concentration the marrow blast decrease index (MBDI) in types M4 and M5 of ANLL is much more greater than in M2 after the first course of chemotherapy and in 3 patients of M2, the serum H level and the MBDI show positive correlation.

The possible role and clinical implication of myeloid-derived suppressor cells in the peripheral blood of patients with hepatitis B virus-related acute-on-chronic liver failure

EFNA1 in gastrointestinal cancer:Expression,regulation and clinical significance

Ephrin-A1 is a protein that in humans is encoded by the EFNA1 gene.The ephrins and EPH-related receptors comprise the largest subfamily of receptor proteintyrosine kinases which play an indispensable role in normal growth and development or in the pathophysiology of various tumors.The role of EFNA1 in tumorigenesis and development is complex and depends on the cell type and microenvironment which in turn affect the expression of EFNA1.This article reviews the expression,prognostic value,regulation and clinical significance of EFNA1 in gastrointestinal tumors.

Colorectal cancer:Artificial intelligence and its role in surgical decision making

Despite several advances in the oncological management of colorectal cancer(CRC),there still remains a lacuna in the treatment strategy,which differs from center to center and on the philosophy of the treating clinician that is not without bias.Personalized treatment is essential for the treatment of CRC to achieve better long-term outcomes and to reduce morbidity.Surgery has an important role to play in the treatment.Surgical treatment of CRC is decided based on clinical parameters and investigations and hence likely to have judgmental errors.Artificial intelligence has been reported to be useful in the surveillance,diagnosis,treatment,and follow-up with accuracy in several malignancies.However,it is still evolving and yet to be established in surgical decision making in CRC.It is not only useful preoperatively but also intraoperatively.Artificial intelligence helps to rectify the human surgical decision when clinical data and radiological and laboratory parameters are fed into the computer and may guide correct surgical treatment.
