Objective To analyze the efficacy of drug-coated balloon in the treatment of hetero-geneous in-stent restenosis.Methods A total of 118 patients who received treatment and diagnosed with heterogeneous in-stent restenosis were selected as study objects,and were divided into two groups using a random table method.The experimental group(n=59)received drug-coated balloon thera-py,and the control group(n=59)received drug-eluting stent therapy.The therapeutic effects of the two different treatment methods on heterogeneous in-stent restenosis were compared.Results There was no significant difference in the incidence of in-stent restenosis in the right coronary artery,cir-cumflex artery,and anterior descending artery between the two groups(P＞0.05).There was no sig-nificant difference between the two groups in the preoperative reference vessel diameter,lesion length,lumen stenosis degree,and localized restenosis(P＞0.05).The postoperative residual ste-nosis rate in the experimental group was significantly higher than that in the control group(P＜0.05).There was no significant difference between the two groups in the preoperative lumen area,neointimal load,stent inner area,neointimal area,incidence of neoatherosclerosis and thrombus(P＞0.05).Operative lumen area of the experimental group was smaller than that of the control group(P＜0.05).No target vessel reconstruction,stent thrombosis,nonfatal myocardial infarction,or cardiac death occurred in two groups during 12 months of follow-up.Conclusion Drug-coated balloons are effective and safe in the treatment of heterogeneous in-stent restenosis,and can obtain similar effects to drug-eluting stents.

Objective To investigate the correlations between lipoprotein associated phospholipase A2(Lp-PLA2),platelet aggregation rate(PAG),the ratio of mean platelet volume to platelet count(MPV/PLT)and major adverse cardiovascular events(MACE)in elderly patients with coronary heart disease(CHD).Methods The clinical data of 162 elderly patients with CHD admitted to Jianhu Hospital affiliated to Nantong University from August 2020 to September 2021 were collected retrospectively.All the patients were treated with aspirin orally and followed up for 1 year.The development of MACE within 1 year was recorded.MACE occurred in 30 patients(development group)and the other 132 patients without MACE were assigned to non-development group.Serum Lp-PLA2,PAG,and MPV/PLT were compared between the 2 groups at admission.Logistic regression was used to analyze the relationship between these parameters and MACE in elderly CHD patients.Receiver operating character(ROC)curve was used to evaluate the value of serum Lp-PLA2,PAG,MPV/PLT alone and jointly at admission in predicting MACE within 1 year.Results The proportions of patients with age≥75 years and hypertension in the development group were significantly higher than those in the non-development group(P<0.05).Serum Lp-PLA2,PAG,MPV/PLT in the development group were also significantly higher than those in the non-development group(P<0.05).Binary logistic regression analysis showed that hypertension,Lp-PLA2,PAG,and MPV/PLT were influence factors of MACE in elderly CHD patients(P<0.05).ROC curve results showed that the area under curve(AUC)values of Lp-PLA2,PAG,MPV/PLT alone or jointly were 0.832,0.817,0.841 and 0.939 in predicting MACE in elderly CHD patients.Conclusion Overexpression of Lp-PLA2,PAG and MPV/PLT are closely related to the development of MACE in elderly CHD patients.During hospitalization,the risk of MACE can be assessed by detecting Lp-PLA2,PAG,and MPV/PLT,and timely clinical intervention can be carried out.

BACKGROUND/AIMS: There has been major progress in our understanding of the irritable bowel syndrome (IBS), and novel treatment classes have emerged. The Rome IV guidelines were published in 2016 and together with the growing body of Asian data on IBS, we felt it is timely to update the Asian IBS Consensus. METHODS: Key opinion leaders from Asian countries were organized into 4 teams to review 4 themes: symptoms and epidemiology, pathophysiology, diagnosis and investigations, and lifestyle modifications and treatments. The consensus development process was carried out by using a modified Delphi method. RESULTS: Thirty-seven statements were developed. Asian data substantiate the current global viewpoint that IBS is a disorder of gut-brain interaction. Socio-cultural and environmental factors in Asia appear to influence the greater overlap between IBS and upper gastrointestinal symptoms. New classes of treatments comprising low fermentable oligo-, di-, monosacharides, and polyols diet, probiotics, non-absorbable antibiotics, and secretagogues have good evidence base for their efficacy. CONCLUSIONS: Our consensus is that all patients with functional gastrointestinal disorders should be evaluated comprehensively with a view to holistic management. Physicians should be encouraged to take a positive attitude to the treatment outcomes for IBS patients.

Probiotics as intestinal flora regulators are increasingly applied in clinical practice;however,the administration of probiotics in immunocompromised individuals is rarely reported.This article is aimed to review the benefits and risks of probiotics in immunocompromised individuals,such as HIV-infected individuals and patients with malignant tumors.The research evidence shows that probiotics can reduce the occurrence of different types of diarrhea,regulate the intestinal immune status and decrease the incidence of complications in immunocompromised patients.Randomized controlled clinical trials have shown that the risk of adverse events is not significantly increased in immunocompromised patients compared to those with intact immune status and the probiotics-related infections are only presented in case reports.

Purpose To explore the accuracy of ALK fused gene expression by immunohistochemistry ( IHC) in non-small cell lung cancer ( NSCLC) patients, and to investigate the clinical and pathological features of ALK-positive NSCLC patients. Methods By u-sing rabbit monoclonal D5F3 antibody, ALK IHC was performed on 234 NSCLC patients. ALK positive cases were confirmed by reverse transcription-polymerase chain reaction ( RT-PCR) . Results The positive incidence of ALK by IHC in 234 NSCLC specimens was 8. 97% (21/234), the positive rate of ALK fused gene verificated by RT-PCR was 5. 98% (14/234). There was significant difference with histological type, age, stage (P<0. 05), but no significant difference with gender, smoking history, tumor differentiation. Of 21 cases of ALK-positive NSCLC patients, the consistency of IHC and RT-PCR was 0 when IHC was ( +) , however, when IHC was or immunohistochemical score was >120, the consistency rate was 100%. Conclusion Although immunohistochemical expres-sion of ALK fused gene may have a certain false positive, IHC or immunohistochemical score> 120 show very high value for ALK fused gene RT-PCR followed by ALK immunohistochemistry in lung cancer is a economical and feasible method for the valuation of ALK fused gene.

Objective To study the significance of morphologic, immunophenotype, cytogenetic features, molecular biology (MICM) and prognosis of t (8;21) acute myeloid leukemia (AML) patients.Methods Morphological, FAB subtypes, flow cytometric immunophenotyping, G-binding technique and RTPCR were performed in 70 AML patients with t (8;21) and AML1-ETO fusion transcripts as compared with normal karyotype 70 AML patients. Results In 70 AML patients with t(8;21), 1 case of M1, 64 cases of M2, 3cases of M4 and 2 cases of ambiguity AL according to FAB classification. The CD13, CD33, CD34 and CD117expression were higher, meanwhile CD19 was positive in 40 %, CD15 was 11%, CD11b was 10 % and CD7 was 7 %. Cytogenetically, 50 % cases had additional chromosomal abnormalities, and main associated recurrent additional abnormalities were loss of a sex chromosome, 9q- and hyperdiploid. AML1/ETO fusion gene transcripts were detected in all 70 AML patients with t(8;21) by RT-PCR. CR rate of t(8;21) AML with CD19were 72 %, t(8;21) AML with CD19 and CD7 were 0; in normal karyotype AML were 31%. Conclusion The t(8;21) is the characteristic chromosome abnormality of M2. In the t(8;21), CD19, CD34 and CD117 expression are high, while CD7 are low. These antigen expression in t(8;21) AML closely correlated with karyotype. CD19 is a marker of good prognosis, but CD7 is a marker of low CR.

Objective To analyze the fusion genes derived from 29 types of chromosome structural aberrations in leukemia patients,and the significances on the MICM typing,risk grouping,and minimal residual disease(MRD)monitoring of leukemia.Methods The bone ulan-ow or blood samples from 141 leukemia patients were analyzed with a novel multiplex nested RT-PCR.In addition.chromosomal karyotypes were investigated in some patients.Results Of the 141 leukemic samples,66(46.8%)carried 13 types of MLL/AF6,MLL/AF9,dupMLL MLI/ENL,CBFβ/MYH11 and TLS,ERG.Fusion genes were positive in 27 of 57 ALL patients(47.4 q%),and 33 of 78 AML patients(42.3%),respectively.In these ALL or AML patients,7 or 6 chromosome structural aberrations were found. Conclusion This multiplex nested RT-PCR reaction could screen 29 types of chromosome structural aberrations at the same time.
