RESUMO
Objective: To explore the onset features and prognosis in "migratory birds" population with acute myocardial infarction (AMI) in Hainan province. Methods: A total of 1246 patients diagnosed as coronary aretery disease and admitted in our Hospital during 2012-2015 were consecutively enrolled, including "Migratory birds" group (n=197) and Hainan group (n=58). Clinical information, risk factors, interventional strategies and in-hospital outcomes were recorded and compared. Results: The patients' age, histories of hypertension, diabetes, smoking and blood lipids were similar between 2 groups. In "Migratory birds" group, the average time from arriving Hainan to AMI onset was (3.15±2.67) days. Compared with Hainan group, "Migratory birds" group had the higher ratio of acute STEMI occurrence [70.56% (139/197) vs 51.72% (30/58), P=0.003], more patients with single+double coronary artery diseases (P=0.009), and thrombus aspiration (P=0.008); while less stent implantation, P=0.007. "Migratory birds" group also presented the higher ratios of cardiac shock after AMI (12.69%vs 3.45%, P=0.044), and cardiac shock+death (16.24% vs 3.45%, P=0.022). Conclusion: "Migratory birds" AMI patients had the higher ratios of acute STEMI, with more simple lesions and thrombus aspiration, they usually had poor prognosis.
RESUMO
<p><b>OBJECTIVE</b>To explore the molecular mechanism of exocrine immune inflammatory injury of Sjögren's Syndrome and the intervention of Banxia Qinlian Decoction (BQD).</p><p><b>METHODS</b>Totally 18 female NOD mice were randomly divided into the model group, the positive drug group, and the BQD group, 6 in each group. Six female BALB/c mice were recruited as a blank control group. Mice in the blank control group and the model group were gavaged with deionized water at the daily dose of 0.1 mL/10 g body weight. Tripterygium Tablet was administered by gastrogavage to mice in the positive group at the daily dose of 10 mg/kg. BQD was administered by gastrogavage to mice in the BQD group at the daily dose of 60 g crude drugs/kg. After 12 weeks of medication, mice were sacrificed. Their eyeballs were excised and blood collected. Tissues of bilateral parotids and submandibular glands were kept. mRNA transcriptional levels of IL-17, IL-6, type 3 muscarinic acetylcholine receptors (M3R), aquaporin protein-5 (AQP5) were detected by RT-PCR. Expression levels of M3R and AQP5 protein were detected by Western blot. Protein expression levels of IL-17 and IL-6 were detected by ELISA.</p><p><b>RESULTS</b>Compared with the normal group, mRNA transcriptional levels and protein expression levels of IL-17, IL-6, M3R, and AQP5 were significantly up-regulated in the model group (P < 0.01). Compared with the model group, mRNA transcriptional levels and protein expression levels of IL-17, IL-6, M3R, and AQP5 were significantly down-regulated in the positive drug group and the BQD group with statistical difference (P < 0.01, P < 0.05). Compared with the BQD group, mRNA-transcriptional levels of IL-17, IL-6, and M3R, as well as M3R and AQP5 protein expression levels were significantly down-regulated in the positive drug group (all P < 0.01).</p><p><b>CONCLUSION</b>The molecular mechanism of BQD in inhibiting SS exocrine neurotoxic injury might be possibly related to regulating Th17/IL-17 immune inflammatory way.</p>
