Objective To explore effects of long-term smoking on secondary prevention for oral aspirin in high-risk stroke patients. Methods A total of 115 high-risk stroke patients who orally took aspirin for secondary prevention in our hospital from August 2012 to August 2014 were selected as the study subjects. According to smoking or not, they were divided into non smoking history group (34 cases) and smoking history group (81 cases). Among them, 36 cases whose smoking time was ≥ 20 years were included in the long-term smoking history group, and 45 cases whose smoking time was 1 to 19 years were included in the short-term smoking history group. The patients were followed up for 12 months. The platelet granule membrane protein (GMP-140), D-dimer (D-D), fibrinogen (FIB), tissue plasminogen activator (t-PA), platelet membrane glycoprotein CD61 and CD62p were determined. The incidence rates of 1-year aspirin resistance and clinical outcome events in the three groups were recorded. Results Before and after treatment, GMP-140, D-D, FIB, CD61 and CD62p in long-term smoking history group were higher than those in short-term smoking history group and non smoking history group while T-PA was lower, and there were significant differences between short-term smoking history group and non smoking history group (P<0.05). The incidence rates of aspirin resistance and clinical outcome events in long-term smoking history group (33.33%, 30.56%) were higher than those in non smoking history group (8.82%, 8.82%)(P<0.05), but there was no significant difference among other groups (P>0.05). Conclusion Long-term smoking history will cause prethrombotic state in stroke patients and increase the incidence rates of aspirin resistance and clinical outcome events.
目的 通过对婴幼儿泌尿系感染并发脓毒症的临床特点、病原菌情况及相关因素的分析,探讨其早期诊断和及时治疗的措施。方法 选取83例我科收治的确诊泌尿系感染合并脓毒症的婴幼儿作为研究对象,回顾性分析其临床表现、实验室检查及治疗预后情况。结果 所选婴幼儿均确诊泌尿系感染合并脓毒症,以男性患儿多见,全身中毒症状重,6月以下多以严重脓毒症、脓毒性休克为首诊表现,尿路刺激症状不明显。有明显细菌感染生物标记物的改变。细菌学培养共检出细菌22株,大肠埃希菌占54.55% (12/22),对头孢吡肟较为敏感,对亚胺培南、美罗培南全部敏感;屎肠球菌占22.73%(5/22),对万古霉素、利奈唑胺、替考拉宁敏感。结论 在婴幼儿常见的感染部位中,泌尿系感染容易被忽略。而小于6月的患儿更易并发严重脓毒症、脓毒症休克等危重症。因此,以脓毒症为首诊表现的婴幼儿应特别警惕泌尿系感染,尽可能早期明确感染部位,防止漏诊。首诊1小时内给予广谱抗生素治疗,可降低婴幼儿脓毒症的病死率,改善患儿预后。
Objective By analyzing the clinical features, laboratory tests, pathogenic bacteria culture and the treatments of infants and toddlers with urinary tract infection UTI accompanied with sepsis, we aim to guide the further clinical treatments and prevention. Methods We selected 83 cases from January 1, 2014 to December 31, 2016 in our hospital as the research objects which were accepted the diagnosis and treatments of urinary tract infection complicated with sepsis. Its clinical manifestations, laboratory tests, bacteriology examination and treatment prognosis were retrospectively analyzed. Results Among the selected infants and toddlers diagnosed with urinary tract infection complicated with sepsis, male patients were more common. Symptoms of systemic poisoning were observed in the majority especially in the children aging under 6 months, with severe sepsis and septic shock as the first manifestation, while conventional symptoms were not obvious. Biological markers of bacterial infection were significantly changed. In bacterial culture, 22 strains of bacteria were detected, Escherichia coli accounted for 54.55% (12/22), were almost sensitive to cefepime, and all sensitive to imipenem and meropenem; Enterococcus following accounted for 22.73% (5/22), could be more sensitive to vancomycin, linezolid, teicoplanin. Conclusion Urinary tract infection is common in under 3 years old babies. Patients aging under 6 months are more likely to be complicated with severe sepsis and septic shock. Therefore, we should be especially vigilant of the UTI among the babies whose first manifestations appear to be sepsis only. It is important to find out the site of infection as early as possible, in order to prevent misdiagnosis. It is also critical to use broad-spectrum antimicrobial therapy within 1 hour when severe sepsis is diagnosed in order to reduce the mortality of sepsis in infants and improve the prognosis.

Objective The Objective of the study was to investigate the effects of the DPP-4 inhibitor on β-cell function in patients with recent-onset latent autoimmune diabetes in adults LADA. Methods Fourteen recently diagnosed LADA patients were randomized into two groups, A and B, to receive insulin therapy with 100 mg/d sitagliptin (group A, n=7) or without sitagliptin (group B, n=7) for 9 months. Results There were no differences in the clinical baseline data between the two groups. During the 9 months of follow-up, there were no significant differences in glucose and glycosylated hemoglobin levels between the two groups. At 9 months, there were not different in group A including fasting C-peptide (FCP), 2-hour postprandial C-peptide (CP), and ΔCP(ΔCP=2 h CP-FCP) levels (P>0.05). Compared with baseline, whereas in group B the levels of FCP, 2-hour CP and ΔCP were significantly decreased compared with baseline (P<0.05). Levels of 2-hour CP were higher in group A, it was higher than group B at 9 months (P<0.05). Conclusion LADA patients treated with sitagliptin and insulin was more likely maintain β-cell function by comparison with insulin alone. Sitagliptin administration in patients with LADA might prolong the insulin-free period.

Objective To investigate the effect of celastrol on the growth of adriamycin-resistant MCF-7/ADR breast cancer cells. Methods The resistance situation of MCF-7/ADR cells to adriamycin and the effect of celastrol on the growth of adriamycin-resistant MCF-7/ADR cells were evaluated by MTT assay. The effect of celastrol on apoptosis in MCF-7/ADR breast cancer cells was determined by annexin V-FITC/PI double staining. The effect of celastrol on cell cycle progression was determined by flow cytometry analysis. Results The resistance index of MCF-7/ADR cells to adriamycin was 14.54. After treatment with celastrol for 48 h, MCF-7/ADR cells displayed markedly inhibited growth in a dose-dependent manner, and calculated IC50 was 1.04 μmol/L. Celastrol decreased the resistance index of MCF-7/ADR from 14.54 to 0.87. The numbers of apoptotic MCF-7/ADR cells, as revealed by annexin V binding, significantly increased upon celastrol treatment (P<0.05). Celastrol treatment caused an increase of cells in G1 phase from (59.22±3.78)% to (77.44±4.21)%, while the percentage of cells in S phase was decreased from(37.51±2.91)% to(19.65±2.25)%(P<0.05). Conclusion These data demonstrated that celastrol induced apoptosis and G1/S cell cycle arrest in MCF-7/ADR cells and consequently displayed potent cytocidal effect on adriamycin-resistant MCF-7/ADR breast cancer cells.

Objective To investigate the therapeutic effects and mechanisms of tetramethylpyrazine (TMP) on streptozocin(STZ)-induced-nephropathy in type 2 diabetic rats. Methods 50 SD rats were randomly divided into normal group(n=10) and model group(n=40). The model rats were fed on high fat and sugar diets for 4 weeks, then given STZ(40 mg/kg,ip). After 72 hours, the fasting blood glucose (FBG) was measured. Rats with high FBG above 16.67mmol/L were randomly divided into four groups: model, metformin(Met, 250 mg/kg)and TMP (80 mg/kg, 160 mg/kg) groups for treating 8 weeks, and both the control and model groups were given equals distilled water by intragastric administration. At the end of the experiment, blood glucose, urine protein, blood urea nitrogen and creatinine were measured. The expression of TLR4 and caspase3 protein in kidney tissue of rats was determined by immunohistochemistry. Pathological changes of kidney were observed under light microscope. Results Compared with the model group, metformin and high dose of TMP administered after 8 weeks, rats can significantly reduce the dynamic fasting blood glucose(P<0.05). Urinary protein excretion of total dynamic decreased significantly (P<0.01, P<0.05); the protein expression of TLR4 and caspase3 in the metformin group and high dose group was significantly lower than that in the model group (P<0.05); kidney tissue pathological damage was significantly reduced. Conclusion TMP has a protective effect on STZ induced nephropathy in type 2 diabetic rats, and its mechanism may be related to the down-regulation of TLR4 expression.
