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.

The potential antiviral and anti-inflammatory mechanism of Anti-601 Mixture, a traditional Chinese medicine compound preparation, was studied by network pharmacology and molecular docking. The chemical constituents and targets of astragali radix, phellodendri chinensis cortex, rhei radix et rhizome, isatidis radix and lonicerae japonicae flos in Anti-601 Mixture were searched by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). The genes corresponding to the target were searched through the UniProt database, and the drug-compound-target (gene) network was constructed by Cytoscape 3.7.2. Then the functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were conducted through Webgestalt to predict the mechanism. The network of drug-compound-target (gene) contained 5 drugs, 100 compounds and 207 targets. Functional enrichment analysis resulted in 717 GO items (P≤0.05), among which 240 were biological process (BP) items, 240 were cell composition (CC) items, and 237 were molecular function (MF) items. The 209 signaling pathways were obtained by enrichment screening of KEGG pathway (P≤0.05). Molecular docking showed that the active ingredients of Anti-601 Mixture, such as Stigmasterol, quercetin, luteolin, acacetin, β-sitosterol, kaempferol,had strong affinity with PTGS2 target. Active compounds in Anti-601 Mixture may regulate multiple signaling pathways including advanced glycation end products and its receptor (AGE-RAGE), IL-17, tumor necrosis factor (TNF) through target of prostaglandin-endoperoxidase synthase 2(PTGS2), thus playing an antiviral and anti-inflammatory role.

Objective To compare the clinical application of Da Vinci robot surgical system (RSS) with traditional open surgery (TOS).Methods From Feb 2015 to Jul 2016,48 cases of upper abdominal surgical disease patients were divided into RSS group (23 cases) and TOS group (25 patients) randomly.Results The anesthesia time [(194 ±16)min vs.(181 ±11)min,t=3.262,P=0.002] and operation time [(167 ± 14) min vs.(158 ± 14) min,t =2.292,P =0.027] were much longer in the RSS,while the blood loss during operation significantly less than the TOS [(128 ± 62) ml vs.(190 ± 86) ml,t =-2.886,P =0.006].The RSS has obvious advantages in 24 h-drainage [(69 ± 27) ml vs.(114 ± 54) ml.t =-3.680,P =0.001],time to out-of-bed activity [(27.7 ± 8.0) h vs.(35.7 ± 9.9) h,t =-3.067,P =0.004],BPS,postoperative exhausting time[(27.2 ±5.9)h vs.(32.8 ±8.3)h,t =-2.690,P =0.01] and length of hospital stay [(10.4 ± 1.8) d vs.(11.8 ± 1.9) d,t =-2.600,P =0.013].But the total hospital cost was higher in RSS [(117 000 ± 10 000) yuan vs.(77 000 ± 8 000) yuan,t =15.087,P =0.000)].Conclusions The RSS is a much minimally invasive surgery,reducing blood loss and postoperative pain,promoting rapid recovery,shortening hospital stay.

Objective To investigate the expression of PD-1 on CD4 +and CD8 + T cells in patients with HBeAg-positive chronic hepatitis B(CHB)treated with telbivudine.Methods Fifty-six HBeAg-positive CHB patients admitted in the First Affiliated Hospital of Zhengzhou University during January 201 3 and June 201 4 were enrolled in this study.The expression of PD-1 on CD4 +and CD8 + T cells was detected with flow cytometry at baseline,24,48 and 72 wks after telbivudine treatment.The relationship of PD-1 expression with alanine aminotransferase (ALT)level,HBeAg seroconversion and HBV DNA loads was analyzed.t test and completely random variance analysis were used to analyze the data.Results The PD-1 expression on CD4 + and CD8 + T cells at baseline was higher in patients with low ALT levels compared to those with high ALT levels(t =1 2.20 and 9.69,both P <0.01 ),while higher levels of PD-1 expression was also observed in patients with high HBV DNA load (≥5 lgIU /mL)compared to those with low HBV DNA load (t =4.39 and 4.85,both P <0.01 ).PD-1 levels on CD4 + and CD8 + T cells presented a declining trend after telbivudine treatment(F =6.98 and 8.97,both P <0.01 ),PD-1 expression in patients with HBeAg seroconversion showed lower levels compared with baseline values (t =1 8.45 and 1 8.01 ,both P <0.01 ). Conclusion In HBeAg-positive CHB patients,the expression of PD-1 on CD4 + and CD8 + T lymphocytes shows a decreasing trend during the treatment with telbivudine,indicating that antiviral therapy may alleviate the immunosuppression in these patients.

To investigate the effects of curcumin on mitochondrial dysfunction induced by high glucose(40 mmol/L glucose, 24 h)in L6 cells, curcumin(10, 20, 40 μmol/L)was administered for 24 h after high glucose culture. The effects of curcumin on the mitochondrial dysfunction were evaluated by mitochondrial membrane potential, reactive oxygen species(ROS), ATP content and mtDNA copy number. The mRNA and protein expression of uncoupling protein 2(UCP2), PPARγ coactivator 1α(PGC-1α)and sirtuin-1(Sirt3)were also determined. As improvement of high glucose damage, curcumin significantly raised mitochondrial membrane potential and ATP content, and decreased ROS level. Curcumin significantly ameliorated the down regulation of UCP2 yet with little effect on mtDNA copy number and PGC-1α and Sirt3 expression. In conclusion, curcumin could significantly ameliorate mitochondrial dysfunction in L6 cells induced by high glucose, which involved the mechanism of multiple antioxidants.

OBJECTIVETo evaluate the clinical value of (18)F-FDG PET/CT in the differentiation between benign lesions and lung cancer for large shadows in patients with pneumoconiosis.

METHODSA retrospective study was conducted in 21 patients with a confirmed diagnosis of pneumoconiosis who had a total of 37 large shadows in the lung fields as shown by whole-body (18)F-FDG PET/CT imaging, and (18)F-FDG uptake was evaluated using the maximum standardized uptake value (SUVmax). Twelve lesions were examined by CT-guided aspiration biopsy, and one case underwent fiberoptic bronchoscopy, as well as tests based on bronchoalveolar lavage fluid and sputum; the other cases were followed up for more than 2 years. The differences between pneumoconiosis nodules with high (18)F-FDG uptake and lung cancer were evaluated by t test.

RESULTSSeventeen lung masses or nodules with high (18)F-FDG uptake were detected in 13 patients; among the 13 patients, 5 lesions of 5 cases were confirmed as non?small cell lung cancer (1 case of squamous cell carcinoma, 3 cases of adenocarcinoma, and 1 case of recurrent squamous cell carcinoma after operation), and 7 lesions of 7 cases were progressive massive fibrosis as shown by CT-guided aspiration biopsy; one case had no tumor cells detected by fiberoptic bronchoscopy, and 2.5-year follow-up revealed no changes in the lesions. The other 8 patients showed no increased (18)F-FDG uptake in their 20 lung nodules, which were confirmed as benign lesions by follow-up. The diameter range of lung cancer was 1.6∼6.8 cm, and the SUVmax range was 4.8∼14.0; the diameter range of pneumoconiosis nodules with high (18)F-FDG uptake was 1.5∼4.6 cm, and the SUVmax range was 2.6∼12.4. There were no significant differences in diameter and SUVmax between the lung cancer and pneumoconiosis nodules with high (18)F-FDG uptake (P > 0.05 for both). (18)F-FDG PET/CT had a specificity of 62.5% (20/32), an accuracy of 67.6% (25/37), a false-positive rate of 37.5% (12/32), and a negative predictive value of 100% (20/20) for the diagnosis of lung cancer. The lung cancer detection rate was 23.8% (5/21).

CONCLUSIONIn (18)F-FDG PET/CT imaging for patients with pneumoconiosis, the lung lesions without (18)F-FDG uptake or symmetrical lesions with high (18)F-FDG uptake are considered as benign pneumoconiosis nodules; however, (18)F-FDG PET/CT might have a limited role in evaluating the solitary lung lesions in patients with pneumoconiosis and needs further study.
