ObjectiveTo study the imaging characteristics of SPN of adenocarcinoma (ASPNs) on 18F-FDG PET/CT.MethodsThe morphological and metabolic features of 35 ASPNs on FDG PET/CT were retrospectively reviewed.SUVmax (SUV) was measured and ΔSUVmax was calculated according to ΔSUVmax =(SUVmax on delay imaging - SUVmax on early imaging)/SUVmax on early imaging × 100％.Statistical analysis was performed by software SPSS 11.5 using t-test,analysis of variance and Fisher exact test.Results( 1 ) Fifteen ASPNs (42.86％,15/35) presented as nodular pattern on FDG PET imaging,while 20 (57.14％,20/35) as lamellar,cloudy or ill-defined patterns.The SUVmax of these ASPNs followed a descending order of nodular,lamellar,cloudy and ill:defined on both early and delay imaging (F =30.696 and 24.758,both P＜0.001).(2)There were 54.29％ (19/35) ASPNs with SUVmax ≥2.5 and 45.71％ (16/35) ASPNs with SUVmax ＜2.5.(3) Of 35 ASPNs,24(68.57％ ) were solid nodules and 11(31.43％) were ground glass nodules with SUVmax =4.54 ±2.69 and 1.30±0.87,respectively (t =-5.234,P ＜O.001 ).(4) The SUVmax of ASPNs on delay FDG imaging (4.22 ±3.52) was significantly higher than that on early imaging (3.49 ±2.72) (t =-4.021,P ＜0.001 ).However,SUVmax was dependent on SUVmax on the early imaging:when SUVmax ≥2.5,ΔSUVmax was positive in 94.74％ (18/19) of ASPNs; while SUVmax ＜2.5,ΔSUVmax was positive in 56.25％ (9/16) of ASPNs (P =0.013).(5) Of 31 ASPNs with cell differentiation data,there were 10/17 well-differentiated ASPNs and 13/14 poorly-differentiated ASPNs with positive ΔSUVmax ( P =0.045 ).The average SUVmax of well-differentiated ASPNs was significantly lower than that of poorly-differentiated ASPNs ( 1.70 ± 1.51 vs 4.91 ± 2.69,t =- 3.951,P ＜ 0.001 ).Conclusions The morphological and metabolic features of ASPNs are diversified.It is common for ASPN to present with SUVmax ＜ 2.5.ΔSUVmax may be helpful for differentiating malignant from benign SPNs.

Background: Acute aortic dissection is known as the most dangerous aortic disease, with management and prognosis determined as the disruption of the medial layer provoked by intramural bleeding. The objective of this study was to evaluate the safety and necessity of antiplatelet therapy on patients with Stanford Type B aortic dissection (TBAD) who underwent endovascular aortic repair (EVAR). Methods: The present study retrospectively analyzed 388 patients with TBAD who underwent EVAR and coronary angiography. The primary outcomes were hemorrhage, death, endoleak, recurrent dissection, myocardial infarction, and cerebral infarction in patients with and without aspirin antiplatelet therapy at 1 month and 12 months. Results: Of those 388 patients, 139 (35.8%) patients were treated with aspirin and 249 (64.2%) patients were not treated with aspirin. Patients in the aspirin group were elderly (57.0 ± 10.3 years vs. 52.5 ± 11.9 years, respectively, χ2 = 3.812, P < 0.001) and had more hypertension (92.1% vs. 83.9%, respectively, χ2 = 5.191, P = 0.023) and diabetes (7.2% vs. 2.8%, respectively, χ2 = 4.090, P = 0.043) than in the no?aspirin group. Twelve patients (aspirin group vs. no?aspirin group; 3.6% vs. 2.8%, respectively, χ2 = 0.184, P = 0.668) died at 1?month follow?up, while the number was 18 (4.6% vs. 5.0%, respectively, χ2 = 0.027, P = 0.870) at 12?month follow?up. Hemorrhage occurred in 1 patient (Bleeding Academic Research Consortium [BARC] Type 2) of the aspirin group, and 3 patients (1 BARC Type 2 and 2 BARC Type 5) in the no?aspirin group at 1?month follow?up ( χ2 = 0.005, P = 0.944). New hemorrhage occurred in five patients in the no?aspirin group at 12?month follow?up. Three patients in the aspirin group while five patients in the no?aspirin group had recurrent dissection for endoleak at 1?month follow?up (2.3% vs. 2.2%, respectively, χ2 = 0.074, P = 0.816). Four patients had new dissection in the no?aspirin group at 12?month follow?up (2.3% vs. 3.8%, respectively, χ2 = 0.194, P = 0.660). Each group had one patient with myocardial infarction at 1?month follow?up (0.8% vs. 0.4%, respectively, χ2 = 0.102, P = 0.749) and one more patient in the no?aspirin group at 12?month follow?up. No one had cerebral infarction in both groups during the 12?month follow?up. In the percutaneous coronary intervention (PCI) subgroup, 44 (31.7%) patients had taken dual?antiplatelet therapy (DAPT, aspirin + clopidogrel) and the other 95 (68.3%) patients had taken only aspirin. There was no significant difference in hemorrhage (0% vs. 1.1%, respectively,χ2 = 0.144, P = 0.704), death (4.8% vs. 4.5%, respectively, χ2 = 0.154, P = 0.695), myocardial infarction (2.4% vs. 0%, respectively,χ2 = 0.144, P = 0.704), endoleak, and recurrent dissection (0% vs. 3.4%, respectively, χ2 = 0.344, P = 0.558) between the two groups at 12?month follow?up. Conclusions: The present study indicated that long?term oral low?dose aspirin was safe for patients with both TBAD and coronary heart disease who underwent EVAR. For the patients who underwent both EVAR and PCI, DAPT also showed no increase in hemorrhage, endoleak, recurrent dissection, death, and myocardial infarction.

OBJECTIVETo establish a method to test citrinin (CIT) in monascus products by immuno-affinity chromatography (IAC)-high performance liquid chromatography (HPLC), and to detect the content of CIT in monascus products in Fujian province.

METHODSIAC-HPLC was applied to detect the CIT content in monascus products. The conditions to use HPLC were as follows: C(18) reversed-phase chromatographic column, 150.0 mm×4.6mm×3 µm; mobile phase: the volume ratio of acetonitrile and 0.1% phosphoric acid solution at 65:35; isocratic elution; column temperature: 28°C; flow velocity: 0.8 ml/min; fluorescence detector, excitation wavelength (λ(ex)) was 331 nm and emission wavelength (λ(em)) was 500 nm. The standard curved was established by the linear regression of peak area (Y) to CIT content (X, ng/ml). The accuracy and precision of the method would then be verified. And 32 kinds of monascus products were determined and their color values were compared by this method.

RESULTThe standard curve established in this study was Y = 4634.8X-136.42, r = 1.000; whose limits of detection was 20 µg/kg and the limits of qualification was 64 µg/kg. In the range between 200 and 800 µg/kg, the standard recovery rate was 98.9% - 110.0% (n = 3), and the relative standard deviation (RSD) was 0.51% - 1.76%. Out of the 32 samples, CIT was detected from 11 samples of monascus rice, 9 samples of monascus powder and 5 samples of monascus pigments, the content was around 0.212 - 14.500 mg/kg. 4 out of 7 functional monascus samples were detected out CIT, whose content at 0.142 - 0.275 mg/kg.

CONCLUSIONThe method to detect CIT in monascus products by IAC-HPLC has been established.

OBJECTIVETo study the clinical effectiveness and safety of nasal intermittent positive pressure ventilation (NIPPV) in the initial treatment of neonatal respiratory distress syndrome (NRDS) and the initial setting of NIPPV parameters.

METHODSOne hundred neonates with NRDS were divided into NIPPV group (n=50) and nasal continuous positive airway pressure (NCPAP) group (n=50). A randomized controlled study was conducted to compare the effectiveness of NIPPV versus NCPAP in the initial treatment of NRDS from the following aspects: reducing CO2 retention, improving oxygenation, reducing second endotracheal intubation and second use of pulmonary surfactant (PS), reducing the duration of invasive respiratory support, reducing the duration of oxygen use, and reducing the incidence of air leak, abdominal distension and ventilator-associated pneumonia.

RESULTSAfter 1 and 6 hours of noninvasive respiratory support, the NIPPV group was superior to the NCPAP group with respect to the reduction in CO2 retention and improvement in oxygenation (P<0.05); in addition, compared with the NCPAP group, the NIPPV group had significantly lower rates of second endotracheal intubation and second PS use, significantly shorter duration of invasive respiratory support and time of FiO2 >0.21, and significantly lower incidence of apnea and ventilator-associated pneumonia (P<0.05); there were no significant differences in the incidence of air leak and abdominal distention between the two groups.

CONCLUSIONSNIPPV is effective and safe in the initial treatment of NRDS and holds promise for clinical application.
