Abstract
Objective: To investigate the effect of non-vitamin K antagonist oral anticoagulants (NOAC) on left atrial or atrial appendage (LA/LAA) thrombi in patients with nonvalvular atrial fibrillation (NVAF). Method: Data from 3 042 patients with atrial fibrillation(AF), who underwent transesophageal echocardiography (TEE) examination before cardioversion or catheter ablation for the detection of LA/LAA thrombus in our department from March 2016 to January 2018 were prospectively analyzed. Among these patients, LA/LAA thrombus was detected by TEE in 57 patients. A total of 19 patients who received dabigatran or rivaroxaban for ≥3 weeks and underwent repeated TEE were included, 38 patients were excluded (7 patients with rheumatic heart disease, 1 patient treated with pericardial decortication, 1 patient treated with surgical repair of endocardial cushion defect, 1 patient with LA thrombus associated with the atrial septal occluder device, 14 patients received warfarin therapy, 14 patients did not receive repeated TEE). Results: First repeated TEE results showed that LA/LAA thrombus was not completely resolved in 4 out of 4 patients treated with dabigatran (110 mg bid) for a median time of 119 (47, 258) days, whereas LA/LAA thrombus was completely resolved in 5 out of 11 patients treated with dabigatran (150 mg bid) for a median time of 80 (58, 147) days. Thrombus was completely resolved in 2 out of 2 patients treated with rivaroxaban (15 mg qd) for 110 days and 95 days respectively, and in 1 out of 2 patients treated with rivaroxaban (20 mg qd) for 91 days. Second repeated TEE was performed in 8 patients. Thrombus was resolved completely in 2 out of 3 patients with undissolved thrombus treated by dabigatran (110 mg bid) after increasing the dabigatran dosage (150 mg bid). Thrombus was resolved in 3 (1 patient prolonged treatment with dabigatran 150 mg bid and 2 patients switched to rivaroxaban 20 mg qd) out of 4 patients with undissolved thrombus under the dabigatran 150 mg bid regimen, whereas the thrombus remained unresolved in 1 patient switched to rivaroxaban (15 mg qd). After receiving rivaroxaban 15 mg bid treatment, the thrombus was finally resolved in 1 patient with undissolved thrombus treated by rivaroxaban 20 mg qd. There was no clinical thromboembolism or major bleeding events during the median follow up time of 462 (305, 558) days. Conclusions: Our data show that NOAC is an effective therapeutic option for the treatment of LA/LAA thrombi. When eligible, a higher NOAC dosage may be preferred due to the higher efficacy on thrombus resolvement.

Abstract
Objective: To evaluate the effect of the ischemic post-conditioning (IPC) on the prevention of the cardio-renal damage in patients with acute ST-segment elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PPCI). Methods: A total of 251 consecutive STEMI patients underwent PPCI in the heart center of Tianjin Third Central Hospital from January 2012 to June 2014 were enrolled in this prospective, randomized, control, single-blinded, clinical registry study. Patients were randomly divided into IPC group (123 cases) and control group (128 cases) with random number table. Patients in IPC group underwent three times of inflation/deflation with low inflation pressure using a balloon catheter within one minute after culprit vessel blood recovery, and then treated by PPCI. Patients in control group received PPCI procedure directly. The basic clinical characteristics, incidence of reperfusion arrhythmia during the procedure, the rate of electrocardiogram ST-segment decline, peak value of myocardial necrosis markers, incidence of contrast induced acute kidney injury(CI-AKI), and one-year major adverse cardiovascular events(MACE) which including myocardial infarction again, malignant arrhythmia, rehospitalization for heart failure, repeat revascularization, stroke, and death after the procedure were analyzed between the two groups. Results: The age of IPC group and control group were comparable((61.2±12.6) vs. (64.2±12.1) years old, P=0.768). The incidence of reperfusion arrhythmia during the procedure was significantly lower in the IPC group than in the control group(42.28% (52/123) vs. 57.03% (73/128), P=0.023). The rate of electrocardiogram ST-segment decline immediately after the procedure was significantly higher in the IPC group than in the control group (77.24% (95/123) vs. 64.84% (83/128), P=0.037). The peak value of myocardial necrosis markers after the procedure were significantly lower in the IPC group than in the control group(creatine kinase: 1 257 (682, 2 202) U/L vs. 1 737(794, 2 816)U/L, P=0.029; creatine kinase-MB: 123(75, 218)U/L vs.165(95, 288)U/L, P=0.010). The rate of CI-AKI after the procedure was significantly lower in the IPC group than in the control group(5.69%(7/123) vs. 14.06%(18/128), P=0.034). The rate of the one-year MACE was significantly lower in the IPC group than in the control group(7.32%(9/123) vs. 15.63% (20/128), P=0.040). Conclusion: The IPC strategy performed eight before PPCI can reduce myocardial ischemia- reperfusion injury, decline the rates of CI-AKI and one-year MACE significantly in STEMI patients, thus has a significant protective effect on heart and kidney in STEMI patients.

Abstract
OBJECTIVE The purpose of this study was to evaluate the clinical efficacy of super-selective intracranial artery infusion chemotherapy and to determine correlated prognostic parameters for advanced lung cancer patients with brain metastases. PATIENTS AND METHODS Fifty-four lung cancer patients with brain metastasis who had no previous treatment were enrolled for the study. These patients received super-selective intracranial artery infusion chemotherapy, as well as arterial infusion chemotherapy for primary and metastatic lesions. The procedure was performed once every 4 weeks. Patients were monitored to evaluate short-term clinical outcomes 4 weeks after the first 2 treatments, and follow-up visits performed every 4 weeks after the first 4 treatments until the appearance of disease progression or intolerable toxicity. RESULTS All 54 cases were treated at least 4 times. The overall response rate was 55.56% (30/54), and the disease control rate was 85.19% (46/54). The median overall survival was 7 months, with a 95% confidence interval (CI) of 5.87-8.13 months, and the median progression-free survival was 4 months, with a 95% CI of 3.20-4.80 months. The 6-month survival rate and 1-year survival rate were 81.48% (44/54) and 18.52% (10/54), respectively. CONCLUSION Super-selective intracranial artery infusion chemotherapy provides a clinically efficacious avenue of treatment for lung cancer patients with brain metastases. Pathological classification, Karnofsky performance status, and extracranial metastases may serve as reliable prognostic parameters in determining the clinical outcomes for lung cancer patients with brain metastases.

Abstract
Purpose of StudyHomocysteine is an independent risk factor of ischemic stroke by promoting vascular endothelial dysfunction and thrombotic process through oxidative stress. We previously found that PFO closure may reduce total homocysteine level (tHcy) in plasma. Here, we compare the effect of PFO closure and medical treatment in reducing mild homocysteinemia in PFO-related stroke patients.Methods Used28 PFO-related stroke patients with mildly elevated tHcy (>12 µmol/l) were prospectively recruited in accordance with IRB. 14 received PFO closure and 14 were treated by medical therapy (antiplatelet/anticoagulant) alone. None of the patients were on folate or vitamin B supplementation. Plasma was collected at baseline and 1 year follow-up after treatment. tHcy level was determined by selected reaction monitoring using mass spectrometry.Summary of ResultsCompared to medical therapy, PFO closure resulted in a lower tHcy level during follow-up (PFO closure: 11.13±3.94 µmol/L, medical therapy: 15.48±3.55 µmol/L, p=0.006), with no difference at baseline (PFO closure: 17.77±4.39 µmol/L, medical therapy: 16.47±7.50 µmol/L, p=0.575). Mild hyperhomocysteinemia patients post PFO closure had a significant reduction of tHcy by 37.34% (p=0.0005), with 71.43% of the patients (10 of 14) having tHcy levels back to normal (<12 µmol/l), while most of medically treated patients (13 of 14) stayed abnormal (p=0.4820) (χ2-test, adjusted p=0.002).ConclusionsWe found that compared with routine medical therapy, PFO closure reduced tHcy level in patients with mild hyperhomocysteinemia. Since PFO stroke patients tend to be younger, the life-time risk of even mildly elevated tHcy may be important for future thrombotic risk. Understanding the mechanism of PFO-related tHcy changes is important in optimizing medical treatment (e.g, folate replacement); studies are ongoing.Abstract MP6 Figure 1

Abstract
Purpose of StudyIV tPA is not routinely followed by blood work due to its reputed short half life. While there has been much focus on tPA's extra-vascular effects on the neurovascular unit in the context of hemorrhagic transformation (HT), little is known about its intravascular efficacy, where it has its intended effect. Emerging data suggest that tPA may be most effective in microvasculature and IV therapy may be a good adjunct to intra-arterial therapy. We previously found that the effect of tPA can last more than 72 hr after stroke onset. Now, we report that even routine blood labs can potentially predict HT.Methods Used72 storke patients with IV tPA were recruited on IRB approval. Clinical coagulation profile (PT, PTT, fibrinogen and D-dimer) were performed at 12, 24, 72 hr post tPA. Patients on medications (e.g. anticoagulants) or with conditions (e.g. liver dysfunction, infection) that may affect these labs were excluded.Summary of ResultsCompared to those without HT, HT patients had significantly higher PT and PTT (Fig A,B) as early as 12 hr post IV tPA and throughout the first 3 days of treatment. ROC analysis suggested PT/PTT at 12 and 24 hr has potential to predict tPA-induced HT (Fig C,D. PT: AUC=0.848, p=0.001; PTT: AUC=0.877; p=0.003).ConclusionsHigher PT/PTT level within 72 hr of IV tPA is early marker of tPA-induced HT. Whether these routine labs have value in symptomatic hemorrhage will require further study in a larger cohort. But this proof-of-concept study suggests that tPA efficacy can potentially be followed in real time. The development of a reliable blood test would be of clinical utility to gauge thrombolytic efficacy in real time to guide and triage adjunct treatments.Abstract MP13 Figure 1

Abstract
Purpose of StudyPFO allows venous clots and vasoactive factors to bypass pulmonary filtration and remain in circulation. We previously identified an immediate reduction of procoagulant serotonin (5-HT) in left atrial blood post PFO closure. To understand the long-term effect of PFO closure, we report the change of 5-HT in peripheral venous blood in 1-year followup.Methods Used97 PFO-related stroke patients were recruited on IRB approval. Venous blood was collected at baseline (BL) and 1 year follow-up (FU) of treatments (PFO closure and medical therapy). Plasma 5-HT was quantified by mass spectrometry. Patients with serotonin modifying medications (ie. SSRIs) or conditions (anxiety/depression) were excluded.Summary of Results5-HT level in peripheral venous blood was significantly reduced by 27.27% (BL: 7.57±8.04 µM; FU: 5.51±5.72 µM; p=0.0034) in 61 patients receiving PFO closure (figure 1A). In the 37 PFO patients treated with medicine alone, no changes were observed (BL: 5.79±7.15 µM; FU: 6.25±6.68 µM; p=0.4050) (figure 1B). 5-HT reduction was independently associated with PFO closure after adjusting for age, gender, medical history and medication status in a multivariate regression (figure 1C).ConclusionsWe found that PFO closure independently reduced 5-HT level in peripheral venous blood. These results support the hypothesis that PFO related right-to-left interatrial shunt may foster higher level of procoagulant and vascoactive substances in circulation. While PFO closure decrease prothrombotic markers immediately post closure, this effect is sustained in long term followup up to 1 year. Further studies on the clinical outcome of these PFO patients with respect to their prothrombotic circulatory profiles are ongoing.Abstract 15 Figure 1

Abstract
Preparation and in vitro/in vivo evaluation of mifepristone intravaginal ring formulations were investigated. In the present study, it is reported that a mifepristone intravaginal ring of reservoir design comprising of a mifepristone silicone elastomer core enclosed in a silicone layer. During the preparation of intravaginal ring solid dispersion method was employed which improved the release rate of drug from the intravaginal ring. In vitro release studies performed under sink conditions and the released drug amounts were estimated using UV spectrometry at 310 nm. In addition, the in vivo release profile of in-house devices was evaluated in female New Zealand white rabbits. The rabbit plasma samples were processed and analyzed using a validated HPLC-MS method. Norgestrel was used as internal standard, and plasma samples contained mifepristone and internal standard were deproteinized, and then subjected to HPLC-MS analysis under condition of electrospray ionization in the selected ion monitoring mode. The drug release from intravaginal ring made in house was constant for 21 days in rabbits, which suggested the mifepristone intravaginal ring release system would be useful in clinical practice in the future. The result indicated the in vitro/in vivo correlation is perfect, which explained in vitro release analysis method developed was feasible.

Abstract
AIMS/HYPOTHESIS Two recent genome-wide association studies have identified several novel type 2 diabetes susceptibility variants in intron 15 of the KCNQ1 gene. We aimed to evaluate the effects of the variants in KCNQ1 on type 2 diabetes and metabolic traits in the population of mainland China. METHODS Three candidate single nucleotide polymorphisms were genotyped in 1,912 individuals with type 2 diabetes and 2,041 normal controls using the ligase detection reaction method. RESULTS We confirmed the association of KCNQ1 with type 2 diabetes in the population of mainland China. Allele frequency ORs of the three single nucleotide polymorphisms (SNPs) were: rs2237892 (OR 1.19, 95% CI 1.08-1.31, p = 3.0 x 10(-4)); rs2237895 (OR 1.20, 95% CI 1.09-1.32, p = 1.9 x 10(-4)); and rs2237897 (OR 1.24, 95% CI 1.13-1.36, p = 3.9 x 10(-5)). We also found a significant difference in the distribution of the global haplotypes between the type 2 diabetes group and the normal control group (p = 2.6 x 10(-5)). In addition, in the control group SNP rs2237892 was marginally associated with increasing fasting plasma glucose and SNPs rs2237892 and rs2237897 were associated with HbA(1c). Furthermore, for all three variants, homozygous carriers of the diabetes-associated allele had significantly decreased BMI and waist circumferences. CONCLUSIONS/INTERPRETATION Our investigation confirmed the effects of KCNQ1 variants on type 2 diabetes risk in the Chinese population.
