Abstract
Objective: To explore the safety and effectiveness of early stent implantation in patients with acute anterior circulation large artery disease. Methods: Patients were recruited from the RESCUE-RE study (a registration study for Critical Care of Acute Ischemic Stroke After Recanalization). Patients who were diagnosed with acute ischemic stroke within 24 hours of onset and given endovascular treatment after consultation from July 2018 to May 2019 from 18 sub-centers nationwide were retrospectively enrolled. According to whether the stents were placed during the operation, the patients were divided into two groups: stenting group and non-stenting group. The baseline between the two groups was matched by propensity score. The matching variables included age, sex, baseline National Institutes of Health Stroke Scale (NIHSS) score, baseline Glasgow Coma Scale (GCS) score, history of stroke, smoking and onset to hospital time. The primary clinical outcome was 90-day good neurological outcome [defined as modified Rankin score (mRS) 0-2]. Secondary outcomes include 90-day mortality, 24-hour re-occlusion of the responsible artery, and symptomatic intracranial hemorrhage. The differences in clinical endpoints between the two groups were compared. Result: A total of 899 patients with acute anterior circulation artery stenosis or occlusion were included in the study, with a mean age of(66±12)years,and 532(59.18%) were male. There were 193 patients in the stenting group and 706 patients in the non-stenting group. After the baseline data between the two groups were matched by propensity score, 169 patients were enrolled in each of two groups respectively. After matching, the proportion of patients in the stenting group with etiological diagnosis of large atherosclerosis [82.53% (137/166) vs 55.69% (93/167)] and the proportion of patients with previous history of hypertension [63.31% (107/169) vs 47.93% (81/169)] in the stenting group were higher than those in the non-stenting group (both P<0.05). While the proportion of patients in the non-stenting group with cardiogenic embolism [37.73%(63/167) vs 11.45%(19/166)]and the proportion of patients with atrial fibrillation [18.93% (32/169) vs 10.65%(18/169)]was higher(all P<0.05). In the stenting group, the time from onset to recanalization was longer[519 (408, 620)min vs 469 (365, 690)min], and the proportion of general anesthesia [50.89% (86/169) vs 35.50% (60/169)] was higher in the stenting group(both P<0.05). In addition, in the stenting group, the proportion of patients receiving mechanical thrombectomy[67.46% (114/169) vs 88.76% (150/169)] and arterial thrombolysis [2.37% (4/169) vs 18.93% (32/169)] was lower than non-stenting group during the operation, while the proportion of patients receiving balloon dilation [53.85% (91/169) vs 13.61% (23/169)]was higher(both P<0.05). The proportion of patients in stent group receiving antiplatelet drugs before operation was higher [13.46% (21/169) vs 8.70% (14/169)](both P<0.05). In terms of clinical outcome, compared with the non-stenting group, the proportion of patients in the stenting group with good neurological function in 90 days was lower [44.79% (73/169) vs 56.36% (93/169)], and the proportion of death at 90 days was higher[15.98% (27/169) vs 8.88% (15/169)] (both P<0.05). There was no significant difference between the two groups in 24-hour re-occlusion[8.88% (15/169) vs 9.47% (16/169)] and symptomatic intracranial hemorrhage[5.92% (10/169) vs 4.76% (8/169)](both P>0.05). Conclusion: For patients with acute anterior circulation artery disease, early stent therapy may increase the proportion of patients with adverse neurological outcomes.

Abstract
Objectives: To investigate the correlation between stress hyperglycemia ratio (SHR) and outcomes in patients with acute ischemic stroke treated with endovascular treatment. Methods: In a multicenter registration study for RESCUE-RE (a registration study for critical care of acute ischemic stroke after recanalization), eligible patients with large vessel occlusion stroke within 24 hours after onset who received endovascular treatment between July 2018 and May 2019 were enrolled. SHR was calculated as the fasting glucose concentration divided by the estimated average glucose concentration and then categorized into four groups according to the quartiles (group Q1, group Q2, group Q3 and group Q4). The primary outcome was poor neurological outcomeat day 90 fromstroke onset [defined as modified Rankin scale (mRS) of 3-6]. Secondary outcomes included early neurological deterioration (END), death within 3 months after stroke onset, and symptomatic intracranial hemorrhage.Multivariable logistic and Cox regression modelswere used to assess the correlation between quartiles of SHR and prognosis in patients with endovascular treatment. Results: A total of 592 patients were enrolled in the study, with a mean age of (63±12) years, and 68.07% were male.The median National Institute of Health stroke scale(NIHSS) score on admission was15(11, 20), and the median SHR was 1.23 (1.07, 1.47), with SHR<1.07 in group Q1, 1.07≤SHR<1.23 in group Q2, 1.23≤SHR<1.47 in group Q3 and SHR≥1.47 in group Q4, respectively. The rate of complete recanalization was lower in group Q4 than that of group Q1 (70.27% vs 83.67%, P=0.026). After fully adjusted for potential covariates, the risk of poor neurological outcome at day 90 from stroke onset in group Q4 was 2.38 folds that of group Q1(adjusted OR= 2.38, 95%CI: 1.57-3.57,P=0.003). The risk of death within 3 months of patients in group Q4 was 1.80 times that of the patients in group Q1, but the difference was not statistically significant(adjusted HR=1.80, 95%CI: 0.90-3.62, P=0.098). Conclusion: Higher SHR was correlated with poor neurological outcome at 3 months in large artery occlusion related acute ischemic stroke patients receiving endovascular therapy.

Abstract
Objective: To investigate the correlation of the expression of platelet microRNA-223 (miR-223) with the degree of platelet activation and the severity of coronary lesions in patients with coronary artery disease (CAD). Methods: A total of 204 consecutive patients underwent coronary artery angiography (CAG) at Beijing Anzhen Hospital between April and December 2016 were enrolled. According to CAG results, all the patients were divided into two groups: 112 patients in CAD group and 92 patients in control group. Real-time fluorescent quantitative PCR was used to detect the expression level of platelet miR-223 and mRNA of its target gene P2Y12. Flow cytometry was performed to detect the expression of platelet associated complement-1 (PAC-1). Results: Compared with control group, the expression level of platelet miR-223 in CAD group was higher [(1.27 (1.17, 1.32) vs 0.73 (0.64, 0.79), P<0.001], while the expression level of P2Y12 mRNA was lower [0.75 (0.51, 0.96) vs 1.00 (0.80, 1.64), P<0.001]. The positive expression rate of PAC-1 of CAD group was higher than that of control group (P<0.001). The expression level of platelet miR-223 was negatively correlated with the expression of P2Y12 (r=-0.39, P=0.02), but positively correlated with the expression of PAC-1 (r=0.50, P<0.001). The platelet miR-223 expression level had a positive correlation with the Gensini score in CAD group (r=0.90, P<0.001), but had no significant correlation with platelet aggregation (r=-0.06, P=0.36). Conclusion: The expression level of platelet miR-223 in patients with CAD may be an indicator for monitoring platelet activation and assessing the severity of CAD.

Abstract
OBJECTIVES Studies on treatment of community-acquired pneumonia (CAP) in China are scarce. We performed a study to investigate empiric antibiotic practices for patients hospitalized with CAP in China and the risk factors for treatment failure. METHODS Data were collected from a national Chinese hospitalization database. Adult patients who were diagnosed with CAP between 1 October 2014 and 30 September 2015 were identified. We studied initial empiric antibiotic regimens, microbiologic sampling, treatment failure, in-hospital mortality and length of hospital stay. RESULTS We included 18 043 adult patients from 185 hospitals who met all the study inclusion criteria. The most common initial antibiotic regimen for CAP was monotherapy with a fluoroquinolone (14.8%, 2671/18 043). The most common initial antibiotic (used alone or in combination with other antibiotics) was levofloxacin (15.7%, 4597/29 278 (this denominator represents the total number of initial antibiotics)). The microbiologic sampling rate was 26.9% (4851/18 043). A total of 4050 (22.4%) of 18 043 patients experienced treatment failure. Multivariate logistic regression demonstrated that older age, male sex, coexisting lung cancer and use of regimens not covering atypical pathogens were risk factors for treatment failure. In-hospital mortality was 2.1% (380/18 043). The median hospital length of stay was 11 days (interquartile range, 8-15 days). CONCLUSIONS Patients receiving Chinese guideline-adherent regimens had better outcomes, and atypical pathogen active regimens were associated with a lower treatment failure rate and shorter length of hospital stay.

Abstract
The aim of this study was to identify changes in the base sequence of the upstream regulatory region of the transthyretin (TTR) gene. Whole-blood DNA was extracted from ten subjects belonging to a family with familial amyloidosis vitreoretinopathy; the upstream regulatory sequence was amplified by polymerase chain reaction, detected by gel electrophoresis, and sequenced. The DNA sequence of the upstream regulatory region of the TTR gene was successfully sequenced, and a point mutation (-743A→T) was identified in six of the ten blood samples: four patients and two family members without disease incidence. Therefore, a point mutation was identified in the upstream regulatory region of the TTR gene in a Han Chinese family with familial vitreous amyloidosis.
