BACKGROUND:
The comparative outcomes of subcutaneous implantable cardioverter-defibrillator (S-ICD) and transvenous ICD (T-ICD) have not been well studied. The aim of this study was to evaluate the safety and efficacy of currently available S-ICD and T-ICD.
METHODS:
The study included 86 patients who received an S-ICD and 1:1 matched to those who received single-chamber T-ICD by gender, age, diagnosis, left ventricular ejection fraction (LVEF), and implant year. The clinical outcomes and implant complications were compared between the two groups.
RESULTS:
The mean age of the 172 patients was 45 years, and 129 (75%) were male. The most common cardiac condition was hypertrophic cardiomyopathy (HCM, 37.8%). The mean LVEF was 50%. At a mean follow-up of 23 months, the appropriate and inappropriate ICD therapy rate were 1.2% vs. 4.7% (χ = 1.854, P = 0.368) and 9.3% vs. 3.5% (χ = 2.428, P = 0.211) in S-ICD and T-ICD groups respectively. There were no significant differences in device-related major and minor complications between the two groups (7.0% vs. 3.5%, χ = 1.055, P = 0.496). The S-ICD group had higher T-wave oversensing than T-ICD group (9.3% vs. 0%, χ = 8.390, P = 0.007). Sixty-five patients had HCM (32 in S-ICD and 33 in T-ICD). The incidence of major complications was not significantly different between the two groups.
CONCLUSIONS
The efficacy of an S-ICD is comparable to that of T-ICD, especially in a dominantly HCM patient population. The S-ICD is associated with fewer major complications demanding reoperation.

Objective To investigate the effectiveness and safety of rosuvastatin and simvastatin in the treatment of hyperlipidemia. Methods The database including CNKI, VIP, Wanfang data base and CBM were retrieved to search the clinical randomized controlled trials (RCT) of rosuvastatin and simvastatin in the treatment of hyperlipidemia, and the data were analyzed with Review Manager 5.2. Results Eighteen RCTs were included with a total sample size of 1819 cases with hyperlipidemia, in which there were 917 patients in rosuvastatin group and 902 in simvastatin group. The Meta-analysis results showed that there were significantly lower serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and significantly higher level of high-density lipoprotein cholesterol (HDL-C) in rosuvastatin group compared with those of simvastatin group [(MD=-0.15, 95%CI:-0.22--0.09, P<0.01), (MD=-0.18, 95%CI:-0.25--0.11, P<0.01), (MD=-0.23, 95%CI:-0.28--0.19, P<0.01) and (MD=-0.11, 95%CI:-0.06--0.15, P<0.01)]. There was no significant difference in the incidence of gastrointestinal adverse reaction between the two groups. Conclusion The current clinical evidences show that rosuvastatin has a better effect on the treatment of hyperlipidemia, and has no adverse reactions.

As an important part of epigenetic marker, DNA methylation involves in the gene regulation and attracts a wide spread attention in biological auxology, geratology and oncology fields. In forensic science, because of the relative stable, heritable, abundant, and age-related characteristics, DNA methylation is considered to be a useful complement to the classic genetic markers for age-prediction, tissue-identification, and monozygotic twins' discrimination. Various methods for DNA methylation detection have been validated based on methylation sensitive restriction endonuclease, bisulfite modification and methylation-CpG binding protein. In recent years, it is reported that the third generation sequencing method can be used to detect DNA methylation. This paper aims to make a review on the detection method of DNA methylation and its applications in forensic science.

AIM: To investigate the efficiency of intravitreal ranibizumab therapy ( IVR ) for polypoidal choroidal vasculopathy ( PCV) in single or multiple polyps.
METHODS: A total 63 patients diagnosed with PCV in Shaoxing City People's Hospital from May 2013 to May 2015 were enrolled and divided into single polyp group and multiple polyps group. All patients received intravitreal ranibizumab 3 monthly and were followed up for 12mo. Observe the changes of best corrected visual acuity ( BCVA ) and central retinal thickness ( CRT ) at different time points.
RESULTS: The single polyps group exhibited a better BCVA, shorter greatest linear dimension, and lower prevalence of fibro - vascular pigment epithelial detachment compared with the multiple polyp group before treatment (P<0. 05). Significant difference of BCVA were observed at 3, 6 and 12mo between the two groups (P<0. 05). BCVA at 3, 6, 12mo was significantly better than that at baseline in single polyps group. The single polyp group exhibited a significantly thinner CRT at 6 and 12mo compared with multiple polyps group (P<0. 05). The single polyp group showed improvement in CRT over the followed up period(P<0. 05). The CRT in multiple polyps group at 3 and 6mo significantly decreased compared with preoperative (P<0. 05).
CONCLUSION: IVR meet better result in PCV patients with multiple polyp and polyp numbers may be valuable to prognosis.

AlM:To compare the efficacy and safety of latanoprost and brimonidine in the treatment of open angle glaucoma, and provide reference for rational drug use.METHODS:A total of 121 cases ( 136 eyes ) who were diagnosed as primary open angle glaucoma were selected in this study, and they were randomly divided into experimental group (62 cases, 70 eyes) and control group ( 59 cases, 66 eyes) according to different drug treatment. Patients in the control group received brimonidine eye drops twice a day, while patients in the experimental group received latanoprost eye drops once a day. The intraocular pressure, visual acuity and adverse reactions were checked of the two groups in the following 3mo.RESULTS:The intraocular pressure of patients in the control group was 18. 1 ± 1. 3mmHg, while the experimental group was 17. 0 ± 0. 9mmHg after 12wk of treatment, which were both lower than before (P<0. 05). The fluctuation of intraocular pressure in the experimental group was significantly lower than that of the control group. There was no significant difference in the LogMAR visual acuity between before and after treatment in the control group, while the LogMAR visual acuity of the experimental group was significantly improved. The control group had hyperemia, burning sensation, tearing, eyelid edema and other adverse side effects, and the experimental group had little adverse reactions. CONCLUSlON: Latanoprost can significantly reduce intraocular pressure in glaucoma patients with in the follow- up time, and reduce the impact of elevated intraocular pressure in the vision of glaucoma patients, with little adverse reaction, worthy of clinical application.

BACKGROUNDThe number of non-responders to cardiac resynchronization therapy (CRT) exposes the need for better patient selection criteria for CRT. This study aimed to identify echocardiographic parameters that would predict the response to CRT.
METHODSForty-five consecutive patients receiving CRT-D implantation for heart failure (HF) were included in this prospective study. New York Heart Association (NYHA) class, 6-minute walk distance, electrograph character, and multi echocardiographic parameters, especially in strain patterns, were measured and compared before and six months after CRT in the responder and non-responder groups. Response to CRT was defined as a decrease in left ventricular endsystolic volume (LVESV) of 15% or more at 6-month follow up.
RESULTSTwenty-two (48.9%) patients demonstrated a response to CRT at 6-month follow-up. Significant improvement in NYHA class (P < 0.01), left ventricular end-diastolic volume (LVEDV) (P < 0.01), and 6-minute walk distance (P < 0.01) was shown in this group. Although there was an interventricular mechanical delay determined by the difference between left and right ventricular pre-ejection intervals ((42.87 ± 19.64) ms vs. (29.43 ± 18.19) ms, P = 0.02), the standard deviation of time to peak myocardial strain among 12 basal, mid and apical segments (Tε-SD) ((119.97 ± 43.32) ms vs. (86.62 ± 36.86) ms, P = 0.01) and the non-ischemic etiology (P = 0.03) were significantly higher in responders than non-responders, only the Tε-SD (OR = 1.02, 95% CI = 1.01 - 1.04, P = 0.02) proved to be a favorable predictor of CRT response after multivariate Logistic regression analysis.
CONCLUSIONThe left ventricular 12 segmental strain imaging is a promising echocardiographic parameter for predicting CRT response.

OBJECTIVETo discuss the effect of calcitonin gene-related peptides (CGRP) on epithelial cadherin (E-cd) expression in human bronchial epithelial cells (HBECs) in vitro.
METHODSThe effect of CGRP on E-cd protein and mRNA expression in both normal and O3-challenged HBECs were determined by immunocytochemistry and RT-PCR. The signal transduction pathways of CGRP were observed by using protein kinase C(PKC) inhibitor (H-7), calmodulin(CaM) inhibitor (W-7) and PKA inhibitor (H-89).
RESULTSCGRP increased E-cd mRNA and protein expressions of normal and O3-challenged HBECs in a dose-dependent manner. CGRP had no effect on cytoplasm E-cd expression. Pre-treatment with H-89, H-7 and W-7, the up-regulatory effect of CGRP on E-cd expression was partly abolished.
CONCLUSIONCGRP increased in cytomembrane E-cd expression of normal and O3-challenged HBECs in a dose-dependent manner. E-cd expression on HBECs was strengthened by CGRP via PKA, PKC and CaM pathways.

OBJECTIVETo explore the anti-aging effect of artemisia burning products (ie. smoke of moxibustion) and its proper intervention parameters.
METHODSAccording to factorial experiment design, 70 SAMP8 mice were randomly divided into one model group (group M) and 6 intervention groups: low concentration with 15 min group (group A1), low concentration with 30 min group (group A2), middle concentration with 15 min group (group B1), middle concentration with 30 min group (group B2), high concentration with 15 min group (group C1), high concentration with 30 min group (group C1). There were 10 cases in each group. Ten age-matched SAMR1 mice were used as normal group (group Z). All the mice in the 6 intervention groups were fumed with artemisia burning products of different concentration and time. The content of serum malondialdehyde (MDA), the activity of superoxide dismutase (SOD) and glutathione reductase (GSH-Px) were tested.
RESULTSMDA content in group M was significantly higher than that in group Z (both P < 0.05), while SOD and GSH-Px activity were significantly lower in group M than that in group Z (both P < 0.05). Results of MDA, SOD and GSH-Px in 6 intervention groups were either of no statistically significant differences, or better than that in group M. Among 6 intervention groups, results of MDA and GSH-Px were better in group B1, while the result of SOD was better in group B2. Time factor didn't make any difference, while concentration of artemisia burning products is meaningful. As to SOD and GSH-Px, there's a strong interaction between the two factors.
CONCLUSIONWith certain concentration and time period, the intervention of artemisia burning products can exert anti-aging effect by increasing antioxydative capability and reducing metabolites of free radicals. Middle concentration and 30 minutes are recommended when intervened with artemisia burning products.

OBJECTIVETo investigate the prognostic value of ultra-sensitive pregnancy associated plasma protein-A (PAPP-A) level in the early phase of acute coronary syndrome (ACS) attack.
METHODSPatients diagnosed as ACS were enrolled and the level of circulatory PAPP-A was measured within 12 hours after ACS attack. The patients were followed at the time of 1st, 6th, and 12th months post-ACS attack in order to observe the incidence of the cardiovascular adverse events. According to the highest quintile, the patients were divided into 2 groups: high level (≥26.08 μg/L) group and low level (<26.08 μg/L) group, to evaluate the association between the level of PAPP-A and the incidence of the cardiovascular events.
RESULTSCompared with the low level group, the incidence of the composite outcome is significantly increased in the high level group, and the values of OR are 4.76, 4.38, 3.75 for 1st, 6th, 12th months respectively (P=0.000). For myocardial infarction (MI) + cardiac death (CD) the values of OR were 9.81, 6.08, 4.12 (P<0.01). Multivariate logistic regression analysis demonstrates that PAPP-A was an independent risk factor for the cardiovascular adverse events in the early, median, and late phase of ACS (P<0.05).
CONCLUSIONIn the early phase of ACS attack, the elevation of PAPP-A is an independent risk factor for the occurrence of cardiovascular adverse events.
