ABSTRACT

AIM: To investigate the effect of low-dose aspirin on primary prevention of non-fatal myocardial and cerebral infarction in patients with type 2 diabetes mellitus. METHODS: From January 2015 to December 2016,40-90 years old patients with type 2 diabetes were treated in the Department of Endocrinology of Yijishan Hospital of Wannan Medical College for more than 2 times (the interval of hospitalization was more than 3 months) , we use the hospital's his system to search out-patient and in-patient files, patients were divided into aspirin group and non-aspirin group according to the use of low-dose aspirin within 1 year after the first visit, the basic data of the first visit were collected: name, sex, age, course of diabetes, systolic and diastolic blood pressure, patients were recorded for laboratory markers including fasting blood glucose, glycated hemoglobin, triglyceride, total cholesterol, Low-density lipoprotein, high-density lipoprotein, creatinine, and platelets, complications such as hypertension, coronary heart disease, atrial fibrillation, hyperlipidemia, diabetic nephropathy and arteriosclerosis were recorded. A Chi square test and a Cox proportional hazard model were used to compare baseline data and cerebrovascular disease after the first use of aspirin. RESULTS: Of the 4 176 patients, 2 137 were type 2 diabetes, 417 were eligible for admission, including 198 males, 219 females, 224 aspirin users and 193 non-users. There was no significant difference in the incidence of cerebral infarction between the aspirin group and the non-aspirin group (χ2=0.820, P=0.365). The incidence of non-fatal myocardial infarction was lower than that of the aspirin non-aspirin group (χ2=10.099, P=0.01) , the incidence of massive hemorrhage was significantly higher than that of aspirin-free group χ2=5.425, P=0.020) . In a subgroup analysis of aspirin use, patients younger than 60 years of age had a lower incidence of ischemic stroke (cerebral infarction) and a risk ratio of 0.428 (95%CI: 0.255-0.719, P=0.001) compared with patients older than 60 years of age, the incidence of cerebral infarction was higher in female patients with a risk ratio of 1.574 (95%CI: 1.018-2.434, P=0.041). CONCLUSION: In this study of patients with type 2 diabetes, low-dose aspirin reduced the incidence of nonfatal myocardial infarction but had no significant effect on the incidence of nonfatal ischemic stroke, and significantly increase the incidence of major bleeding events, we should reconsider the use of low-dose aspirin as a potential benefit of nonfatal cerebral infarction in patients with type 2 diabetes.

ABSTRACT

Objective:To investigate the effect of cisplatin on the expression of programmed death factor ligand 1 (PD-L1) in SGC-7901 cells of gastric cancer and the regulation of lymphocyte on the proliferation of gastric cancer cell.Methods:Flow cytometry was used to detect the expression of PD-L1 on the surface of SGC-7901 cells. After cisplatin pretreatment, SGC-7901 cells were co-incubated with the activated lymphocytes. In group B, SGC-7901 + lymphocytes were not treated with cisplatin. Cisplatin treated SGC-7901 + lymphocytes were in group C. The apoptosis of CD 4+ and CD 8+ T cells in each group was detected by flow cytometry. The dissolution rate of SGC-7901 cells was calculated by ADCC method. Results:MTT results showed that cisplatin inhibited the proliferation effect of SGC-7901 cells in a concentration-dependent manner after 48 h′ cisplatin treatment ( F = 128.35, P < 0.05). After SGC-7901 cells were treated with cisplatin for 0, 0.5, 1.0, 2.0, 4.0 mg/L, the expression of PD-L1 on the cell surface was up-regulated, and after cisplatin treatment for more than 1.0 mg/L, the expression began to decline ( F = 477.79, P<0.05). After cisplatin treatment, SGC-7901 cells were co-incubated with lymphocytes, which increased the apoptosis rate of lymphocytes ( F = 524.98 and 122.47, P<0.05). When human peripheral blood mononuclear cells and target SGC-7901 cells were incubated, cisplatin could mediate the killing activity of human peripheral blood mononuclear cells on human SGC-7901 cells, (ADCC effect), and cisplatin could weaken the killing activity ( t = 15.961, P < 0.05). Conclusions:Cisplatin may inhibit the killing activity of human peripheral mononuclear cells to SGC-7901 cells of gastric cancer and weaken the death of gastric cancer cells by inducing the expression of PD-L1 in SGC-7901 cells.

ABSTRACT

Objective To analyze the molecular genetic basis of novel allele HLA-B * 9534 and establish the allele group specific primer PCR method. Methods Genomic DNA was extracted from whole blood by commercial DNA extraction kit. The HLA-B exons 1 to 8 coding sequences of the proband were am-plified by PCR and the amplification product was purified with double enzymes digestion and both strands of exons 2, 3 and 4 were sequenced. The exon 2-4 amplification of the HLA-B * 9534 was performed with al-lele group specific primers PCR and the PCR product was directly sequenced for exon 2 to 4. Results The proband has two HLA-B alleles. The result was assigned for HLA-B * 1518 and B * 4601 combination with a mismatch in 593A/G heterozygote by DNA sequencing of exon 2 to 4 with loci primers. After separating the two alleles of the proband with allele group specific primers polymerase chain reaction method, HLA-B * 4601 and HLA-B * 9534 alleles were identified after sequencing. The HLA-B * 9534 is identical to HLA-B * 1518 except for one nucleotide substitutions in exon 3 at position 593 A→G, this results in amino acid substitution at cedon 174 from Asn to Ser. The sequences of the novel allele have been submitted to GenBank (EU046491) and the allele has been officially nominated by the WHO Nomenclature Committee. Conclusion Identification of a novel HLA-B * 9534 allele and allele group specific primer PCR for HLA-B * 9534 was re-liable.

ABSTRACT

Objective To analyze the nucleotide sequences of novel allele HLA-B*4608. Methods Genomic DNA of the proband was extracted from whole blood by the commercial DNA extraction kit. The HLA-B exons 1-8 of the proband was amplified and the amplified product was cloned by TOPO TA cloning sequencing kit to split the two alleles apart. Both strands of exons 2, 3 and 4 of chosen colonies were sequenced. Results The sequencing results showed HLA-B alleles of the proband as B*5502 and a new allele as proved by blast search. The sequences of the novel allele have been submitted to Genbank(DQ177521,DQ177522,DQ177523). The new allele is similar to HLA-B*4601 except for two nucleotide substitutions in exon 3: T to C at nucleotide position 538 and G to T at nucleotide position 539. These result in an amino acid substitution at codon 156 from W to L. Conclusion This allele is a novel allele and has been officially named B*4608 by the WHO Nomenclature Committee.
