Chimeric antigen receptor T-cesll therapy(CAR–T)has achieved groundbreaking advancements in clinical application,ushering in a new era for innovative cancer treatment.However,the challenges associated with implementing this novel targeted cell therapy are increasingly significant.Particularly in the clinical management of solid tumors,obstacles such as the immunosuppressive effects of the tumor microenvironment,limited local tumor infiltration capability of CAR–T cells,heterogeneity of tumor targeting antigens,uncertainties surrounding CAR–T quality,control,and clinical adverse reactions have contributed to increased drug resistance and decreased compliance in tumor therapy.These factors have significantly impeded the widespread adoption and utilization of this therapeutic approach.In this paper,we comprehensively analyze recent preclinical and clinical reports on CAR–T therapy while summarizing crucial factors influencing its efficacy.Furthermore,we aim to identify existing solution strategies and explore their current research status.Through this review article,our objective is to broaden perspectives for further exploration into CAR–T therapy strategies and their clinical applications. 展开更多

BACKGROUND In rare instances,primary liver cancer can be associated with intraocular metastasis(IOM).AIM To investigate the correlation between a diverse range of clinical characteristics and IOM in diabetic patients with primary liver cancer,and to determine potential risk factors in predicting IOM.METHODS We recruited a total of 722 diabetic patients with primary liver cancer.The differences between the IOM and non-intraocular metastasis(NIOM)groups in these patients were assessed using the chi-squared test and Student’s t-test.Binary logistic regression analysis was subsequently used to determine risk factors.Finally,the diagnostic value of IOM in this cohort with primary liver cancer was analyzed by receiver operating characteristic(ROC)curve analysis.RESULTS In all,13 patients had IOM.There were no remarkable intergroup differences with respect to age,sex,histopathological sub-types,or blood biochemical parameters.However,the IOM group had significantly higher alpha-fetoprotein(AFP)and cancer antigen 125(CA125)values than the NIOM group.Binary logistic regression identified AFP and CA125 to be significant risk factors for IOM in diabetic patients with primary liver cancer.ROC curve analysis showed that the area under the curve values for AFP and CA125 were 0.727 and 0.796,with the cut-off values of 994.20 ng/mL and 120.23 U/mL,respectively.The sensitivity and specicity for AFP were 92.3%and 59.9%,while those for CA125 were 84.6%and 70.1%,respectively.CONCLUSION Elevated AFP and CA125 represent significant risk factors for IOM in diabetic patients with primary liver cancer. 展开更多

So, early detection and management are mandatory. Aim: To evaluate the role of Von Willebrand factor (VWF) in predicting the presence of OVs. Patients and Methods: 62 patients with liver cirrhosis representing different Child-Pugh classes were included. The diagnosis of liver cirrhosis was based on the combination of clinical, laboratory and US examinations. All included patients underwent the following investigations: complete blood count, liver function tests (ALT, AST, serum bilirubin, albumin and total protein, prothrombin time (PT) and concentration (PC), INR and serum alkaline phosphatase), serum creatinine, Von Willebrand factor antigen (VWF-Ag) measurement and abdominal US. Upper endoscopic evaluation was done to detect presence or absence of varices (esophageal or gastric) and/or PHG. Results: 38 males and 24 females with their mean age (46 ± 12 years old) were included. Plasma Von Willebrand factor-Ag level was significantly higher in patients with OVs than those without varices (P value = 0.000). Also, its level was significantly higher in patients with higher grade of OVs, G3 than those with G1 or G2 (P value = 0.000). Patients with large OVs including those with G2 and G3 showed significantly higher values of VWF than those with small OVs (NO and G1) (P value = 0.000). VWF was independent predictor for detecting the presence of OVs with good sensitivity (90), specificity (77.3) and accuracy (85.5) at a cutoff value of 1.74 U/ml. Also it was an independent predictor for detecting the presence of large OVs with good sensitivity (91.2), specificity (85.7) and accuracy (88.7) at a cutoff value of 2.16 U/ml. Conclusion: VWF-Ag could be used as a non invasive laboratory independent predictor for the detection of OVs. 展开更多

Gastrointestinal(GI)cancers,including malignancies in the gastrointestinal tract and accessory organs of digestion,represent the leading cause of death worldwide due to the poor prognosis of most GI cancers.An investigation into the potential molecular targets of prediction,diagnosis,prognosis,and therapy in GI cancers is urgently required.Proliferating cell nuclear antigen(PCNA)clamp associated factor(PCLAF),which plays an essential role in cell proliferation,apoptosis,and cell cycle regulation by binding to PCNA,is a potential molecular target of GI cancers as it contributes to a series of malignant properties,including tumorigenesis,epithelial-mesenchymal transition,migration,and invasion.Furthermore,PCLAF is an underlying plasma prediction target in colorectal cancer and liver cancer.In addition to GI cancers,PCLAF is also involved in other types of cancers and autoimmune diseases.Several pivotal pathways,including the Rb/E2F pathway,NF-κB pathway,and p53-p21 cascade,are implicated in PCLAF-mediated diseases.PCLAF also contributes to some diseases through dysregulation of the p53 pathway,WNT signal pathway,MEK/ERK pathway,and PI3K/AKT/mTOR signal cascade.This review mainly describes in detail the role of PCLAF in physiological status and GI cancers.The signaling pathways involved in PCLAF are also summarized.Suppression of the interaction of PCLAF/PCNA or the expression of PCLAF might be potential biological therapeutic strategies for GI cancers. 展开更多

An immunostimulatory factor was identified to be secreted by antigen-pulsed maorophages. This factor was able to induce the generation of antigen specific T helper lymphocytes in vitro as well as in vivo. Further in vitro experiments testing for the genetic restriction of this factor indicated that it is a genetically-restricted antigen specific factor (ASF). The Cunningham plaque assay was used to quantify the generation of T helper lymphocytes by measuring the number of plaque forming cells after sequential incubations of antigen-pulsed maorophages with T lymphocytes, and then spleen cells, and finally the TNP-coated sheep red blood cells. 展开更多

Psoriatic arthritis is an inflammatory arthritis associated with psoriasis.Both rheumatoid factor and anti-cyclic citrullinated peptide antibodies positive psoriatic arthritis patients may be in risk for development of symmetrical polyarthritis pattern.Symmetrical polyarthritis pattern was predominant(42%)among clinical pattern of psoriatic arthritis.Among 10 rheumatoid factor positive patients,8(80%)patients had symmetrical polyarthritis pattern and out of 7 anti-cyclic citrullinated peptide antibody positive patients,7(100%)patients had symmetrical polyarthritis pattern.Association of anti-cyclic citrullinated peptide(P=0.008)and rheumatoid factor(P=0.006)showed statistical significance with symmetrical polyarthritis pattern.Human leukocyte antigen-B*07,*38 and human leukocyte antigen-C*07 were predominantly found in rheumatoid factor and anti-cyclic citrullinated peptide positive psoriatic arthritis patients.Background:Psoriatic arthritis is an inflammatory arthritis associated with psoriasis.It is usually seronegative in nature but a small percentage of patients may be positive for rheumatoid factor and anti-cyclic citrullinated peptide antibodies.Anti-cyclic citrullinated peptide and rheumatoid factor are highly specific for rheumatoid arthritis but their role is not clear in psoriatic arthritis.The prevalence and prognostic value of anti-cyclic citrullinated peptide antibody and rheumatoid factor in psoriatic arthritis patients is not well known.The aim of this study was therefore to investigate the prevalence of anti-cyclic citrullinated peptide antibodies and rheumatoid factor in psoriatic arthritis patients and assess their clinical associations and also to see the distribution of human leukocyte antigen-B and human leukocyte antigen-C locus antigens in anti-cyclic citrullinated peptide antibody and rheumatoid factor positive psoriatic arthritis patients.Methods:Fifty patients with psoriatic arthritis were tested for the presence of rheumatoid factor and anti-cyclic citrullinated peptide antibodies.Polymerase chain reaction was done with sequence specific primer for detection of human leukocyte antigen-B and human leukocyte antigen-C locus antigens in rheumatoid factor and anti-cyclic citrullinated peptide positive psoriatic arthritis patients.Data on five clinical patterns of rheumatological manifestations of psoriatic arthritis patients were collected prospectively on all patients and statistically compared between anti-cyclic citrullinated peptide,rheumatoid factor positive and negative patients by chi-square test.We also see the distribution of human leukocyte antigen-B and human leukocyte antigen-C locus antigens in anti-cyclic citrullinated peptide antibody and rheumatoid factor positive psoriatic arthritis patients.Results:Among 50 psoriatic arthritis patients,rheumatoid arthritis test was positive in 10(20%)patients and anti-cyclic citrullinated peptide was positive in 7(14%)patients.Symmetrical polyarthritis pattern is predominant among clinical pattern of psoriatic arthritis which was found in 21(42%)patients.Among 7 anti-cyclic citrullinated peptide positive psoriatic arthritis patients,symmetrical polyarthritis pattern is predominant and it was found in 7(100%)patients.Among 10 rheumatoid factor positive psoriatic arthritis patients,symmetrical polyarthritis pattern is predominant and it was found in 8(80%)patients.In this study,symmetrical polyarthritis pattern is statistically associated with anti-cyclic citrullinated peptide positive psoriatic arthritis patients(P=0.008)and rheumatoid factor positive psoriatic arthritis patients(P=0.006).Human leukocyte antigen-B*07,*38 and human leukocyte antigen-C*07 were predominantly found in rheumatoid factor and anti-cyclic citrullinated peptide positive psoriatic arthritis patients.Conclusion:Both rheumatoid factor and anti-cyclic citrullinated peptide positive psoriatic arthritis patients may be in risk for development of symmetrical polyarthritis pattern.Among rheumatoid factor and anti-cyclic citrullinated peptide positive psoriatic arthritis patients,Human leukocyte antigen-B*07,*38 and human leukocyte antigen-C*07 alleles were more frequently found alleles. 展开更多

Background:Pancreatic cancer is a malignant tumor of the gastrointestinal tract.Due to its insidious onset,most patients with newly diagnosed pancreatic cancer have missed the opportunity for radical surgery,which offers patients the best chance of survival.The 5-year survival rate of patients with pancreatic cancer can be improved with early diagnosis,and serum tumor makers are an inexpensive and convenient diagnostic tool that is widely used in the diagnosis of malignancies.Objective:To determine the diagnostic value of vascular endothelial growth factor(VEGF),carbohydrate antigen 19-9(CA 19-9),and carcinoembryonic antigen(CEA)in patients with pancreatic cancer and the risk factors of vascular invasion.Methods:An experimental group comprising 52 patients with pancreatic cancer admitted to our department from July 2021 to July 2022 and a control group comprising 21 patients with benign pancreatic diseases during the same period were included in our study.Their serum VEGF,CA 19-9,and CEA levels were detected and compared between the two groups,and the correlation between the three markers in the invaded vessel and non-invaded vessel groups was investigated.The diagnostic value of a single tumor marker and in combination for pancreatic cancer was analyzed,and the three tumor marker levels of the experimental group in different pathological characteristics were detected and compared.Results:The experimental group had higher serum VEGF,CA 19-9,and CEA levels than the control group(P<0.05).Through a receiver operating characteristic(ROC)curve analysis,the combined detection had the highest value for the diagnosis of pancreatic cancer,in which the area under the curve(AUC)was 0.9158(95%CI:0.8415-0.9900),while the sensitivity and specificity were 76.19%and 98.08%,respectively.Serum VEGF and CA 19-9 levels were higher in stage Ⅲ-Ⅳ pancreatic cancer patients and those with tumor metastasis compared with stage Ⅰ-Ⅱ patients and those without metastasis(P<0.05),respectively.Binary logistic regression analysis was performed to determine the risk factors of vascular invasion in pancreatic cancer,and the results showed that only serum VEGF was a risk factor(P<0.05),OR(95%CI):1.001-1.006.Conclusion:Patients with pancreatic cancer have significantly higher serum VEGF,CA 19-9,and CEA levels,and the combined detection of tumor markers is of high clinical value in its diagnosis.In addition,serum VEGF is an independent risk factor of vascular invasion in pancreatic cancer,which can predict vascular invasion to a certain extent. 展开更多
