Objective To study the relationship between morning blood pressure surge with carotid artery intima-media thickness in good controlled elderly hypertensive patients.Methods A total of 151well controlled elderly hypertensive patients was selected in this study.Through the ABPM examination,the morning blood pressure peak was calculated,and then these patients were divided into two groups according to the morning blood pressure peak.The patients whose morning blood pressure peak ≤30 mmHg were divided into non-morning blood pressure surge group (NMS group),and the patients whose morning blood pressure peak ＞ 30 mmHg were divided into morning blood pressure surge group (MS group).The carotid IMT of these patients was measured with ultrasonic detection.The hypertension-related factors with blood pressure and morning peak phenomenon and the impact of IMT were analyzed,and the relationship between the morning blood pressure peak and IMT was analyzed with linear regression analysis.Results Two groups of 151 cases were well-controlled hypertension,76 patients with morning blood pressure showed peak phenomenon,accounting for 50.3％.Age,gender,body mass index,blood lipids,blood glucose,the maximum systolic blood pressure,average systolic blood pressure,minimum systolic blood pressure,maximum diastolic blood pressure,average diastolic blood pressure and minimum diastolic blood pressure had no difference between the two groups ( P ＞ 0.05 ).However,the morning blood pressure peak in patients with MS group [ (42.34 ± 7.10)mmHg] and IMT [ (0.89 ± 0.13 )mm] was higher than the NMS group [ (21.16 ±5.23) mmHg,(0.84 ±0.14) mm,P ＜0.01 orP ＜0.05],and carotid IMT and peak morning blood pressure was positively correlated ( r =0.56,P ＜0.01 ).Conclusions Good controlled elderly hypertensive patients remained the phenomenon of the morning blood pressure surge,the morning blood pressure peak might lead to carotid atherosclerosis.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive and lethal human cancers. Cur-rent studies on the relationship between complicated type 2 diabetes mellitus (T2DM) and PDAC prognosis have demonstrated inconsis-tent results. The present study aimed to determine the relationship between complicated T2DM and the clinicopathological characteris-tics of PDAC, and evaluate whether complicated T2DM is a significant predictor for overall survival in patients with resectable PDAC. Methods: In this study, clinicopathological characteristics were observed in 136 patients who underwent surgery for PDAC at the Shengjing Hospital of China Medical University between January 2009 and February 2011. The relationship between complicated T2DM and overall survival of PDAC patients was analyzed using univariate and multivariate analyses. Results:The median age of pa-tients was 60 years (range: 35-80 years). Among the 136 patients, 76(55.9%) were male. The prevalence of complicated T2DM was 27.9%in 136 PDAC cases. Preexisting T2DM was not associated with any of the clinicopathological characteristics (all P>0.05). Uni-variate analysis showed that complicated T2DM (P=0.045), maximum diameter (P=0.011), histological differentiation (P=0.013), pT stage (P=0.034), vessel invasion (P=0.032), and pTNM stage (P=0.030) were significantly associated with the overall survival of PDAC patients. The median overall survival time was 14.2 months for T2DM patients, and 18.8 months for non-T2DM patients. In mul-tivariate analysis, complicated T2DM [hazard ratio (HR), 1.873;95%confidence interval (CI), 1.187-2.954;P=0.007], poorly differenti-ated tumor (HR, 2.647;95%CI, 1.413-4.957;P=0.002), and maximum diameter≥4.0 cm (HR, 1.699;95%CI, 1.094-2.640;P=0.018) were the independent predictors associated with poor overall survival. Conclusion:Complicated T2DM was associated with poor prog-nosis. It could be used as a prognostic predictor in patients with resectable PDAC. If confirmed, these findings may provide a novel ap-proach for individualized adjuvant therapy.

Objective To investigate the risk factors,management and prophylaxis of dangerous placenta previa.Methods The clinical data of 407 cases of placenta previa were reviewed,36 cases of them with dangerous placenta previa.Comparison was made between group A (dangerous placenta previa,36 cases) and group B (non dangerous placenta previa,371 cases) in terms of age,number of pregnancy and number of ceasarean delivery.Results The incidence rates of pregnant women in group A age ≥ 35years,number of pregnancy ≥3times,and cesarean delivery≥2times were 55.6％,61.1％,25.0％,which were significantly higher than those of group B (25.6％,27.7％,2.4％),the differences were statistically significant (x2 =7.71,8.99,21.97,all P ＜ 0.01).Among the 36 cases of dangerous placenta previa,12 cases were diagnosed with concomitant placenta increta.The specificity and sensitivity for detection of placenta increta were 90.5％ (19/21) and 83.9％ (10/12) of ultrasonography respectively,and those were 100.0％ (3/3) and 87.5％ (7/8) of MRI.Of the 36 dangerous placenta previa patients,two patients were treated with induced labour due to unexpected pregnancy under 28 weeks,while the others were refer to surgical operation.5 surgical patients experienced uncontrollable postpartum haemorrhage which necessitated histectomy,while the other 31 cases received conservative operation.Rate of histectomy was 13.9(5/36).Conclusion Dangerous placenta previa is associated with advanced age,multiple pregnancy and multiple cesarean delivery.Accurate preoperational evaluation of the placenta previa should be acquired with ultrasonography and MRI to detect placenta increta,provide information for treatment selection,and prevent postpartum haemorrhage.

OBJECTIVE:To compare in vivo and in vitro permeation behaviors of the ethosome gels of testosterone,testoster-one propionate and testosterone undecanoate. METHODS:The ethosome gels of testosterone,testosterone propionate and testoster-one undecanoate were prepared. With cumulative permeating amount and permeation rate as the indexes,Franz diffusion cell and HPLC were employed to compare in vitro permeation behaviors of 3 kinds of ethosome gels in mouse skin. With testosterone patch as the positive control drug, electrochemistry method was adopted to detect the concentration of testosterone in plasma 0,3,6, 9,12,24,36 and 48 h after applying such 3 kinds of ethosome gels on the back of rats,and then pharmacokinetic parameters were calculated with DAS 2.0 software. RESULTS:24 h cumulative permeating amounts of the ethosome gels of testosterone,tes-tosterone propionate and testosterone undecanoate were(234.31±13.8),(175.63±41.1)and(72.60±15.3)μg/cm2,and the per-meation rates were(10.25±1.9),(7.64±1.4)and(2.96±0.8)μg/(cm2·h),respectively. The pharmacokinetic parameters of the above-mentioned three kinds of ethosome gels and the positive control drug were respectively as follows as cmax of(20.19±2.57), (17.50±2.91),(0.23±0.04),(14.97±2.12)ng/ml,t1/2Ka of(2.80±0.45),(3.36±0.59),(4.02±0.62),(4.20±0.71)h,AUC0-48 h of(13.85±1.96),(13.93±2.13),(0.35±0.07),(11.76±2.31)ng·h/ml. CONCLUSIONS:in vivo and in vitro permeation behav-iors of the ethosome gels of testosterone and testosterone propionate are fairly good.

IFIT family genes are a kind of interferon stimulated genes (ISGs), and play important roles in antiviral sector and immunity regulation. To study the regulatory effect of IFIT family genes during influenza A virus (IAV) infection, we used RNA-sequencing analysis (RNA-Seq) technique and found that when 293T cells were infected by A/WSN/33 (WSN), the concentration of IFIT family genes were increased. Further study reveals that overexpression of IFIT2 or IFIT3 could inhibit IAV replication and transcription, and cause the dose-dependent inhibition of polymerase activity of vRNP. In addition, IFIT2 and IFIT3 encoding protein could colocalize with NS1 in 293T cells infected by WSN, indicating that they might interact with each other. The results suggest that IFIT family genes can inhibit the replication and transcription of IAV, which contributes to our understanding of the regulatory effect of host factors during influenza virus infection.
