Objective To investigate the characteristics of serum oxidized low density lipoprotein (ox-LDL) and traditional cardiovascular risk factors of premature coronary artery disease (PCAD). Methods Sixty-six patients with coro-nary atrery disease (CAD) confirmed by angiography were selected to be PCAD group, and 56 patients with normal coronary artery confirmed by angiography were included in control group. The serum levels of ox-LDL, high density lipoprotein choles-terol (HDL-C), triglyceride (TG), creatinine (SCr), uric acid (UA), other serum biochemical indicators and differences of the proportions of male, hypertension, diabetes, smoking history and family history of CAD were compared between two groups. Results (1)There were higher serum values of ox-LDL, TG, SCr, UA, fasting blood glucose (FBG) and proportion of male pa-tients in PCAD group than those of control group (P＜0.05), but there was a lower plasma level of HDL-C in PCAD group than that of control group (P＜0.05). There were significant differences in other indicators between two groups. (2) There were positive correlations between UA, SCr and ox-LDL ( rs were 0.243 and 0.186 respectively, P were 0.006 and 0.034 respective-ly). (3)The logistic regression analysis showed that ox-LDL, HDL-C and SCr were influential factors to PCAD(OR were 1.155, 0.143 and 1.052 respectively). Conclusion Elevations of ox-LDL, HDL-C and SCr are independent predictors of PCAD.

Objective To investigate the risk factors of premature atherosclerotic three-vessel coronary artery dis?ease (CHD), and the association between single nucleotide polymorphism (SNP) of CD36 rs3211956, rs7755 and premature CHD. Methods Patient with premature three-vessel coronary artery disease (n=102) which were confirmed by consecutive coronary angiogram (lesion group) and patients (n=72) without CHD (control group) were enrolled in the study. Conventional CHD risk factors were compared between the two groups as well as SNPs of CD36 rs3211956 and rs7755 to disclose inde?pendent risk factor for CHD, which were measured by mass spectrometry. Results Among the conventional CHD risk fac?tors, male, HBP, high LDL-C, low HDL-C were independent risk factors of premature CHD. The GT genotype proportion of rs3211956 was significantly lower (χ2=8.042,P=0.005) in the lesion group than that in control group while the TT genotype proportion is significantly higher in lesion group compared with that in control group (χ2=6.191,P=0.014). Patients with the TT genotype have higher score of BMI than patients with GG or GT genotype (P=0.037). The G allele proportion of rs7755 in the lesion group was significantly higher than control group (χ2=3.636, P=0.047). Patients of the GG genotype have higher scores of BMI but lower level of HDL-C than those with AA or AG genotype (P<0.001). Logistic regression analysis re?vealed that after excluding a number of confounding factors, GG and TT genotype of rs3211956 and GG and GA genotype of rs7755 were respectively one of the independent risk factors for premature CHD. Conclusion The SNPs of CD36 rs7755 and rs3211956 may be the independent risk factors of premature coronary heart disease and might affect the the onset of CHD by affectting BMI and HDL-C.

Objective: To explore the occurrence rate of permanent pacemaker implantation (PPI) with relevant risk factors in patients after mechanical aortic valve replacement. Methods: A total of 1986 consecutive patients with mechanical aortic valve replacement were enrolled in this study. According to PPI conduction caused by severe arrhythmia , the patients were divided into 2 groups: PPI group,n=61 including 27 male with the average age of (53.6 ± 9.03) years and Non-PPI group,n=1925. The median follow-up time was (4.47 ± 4.36) years after valve replacement. Results: The patients in PPI group were with the elder age and higher ratio of pre-existing atrial ifbrillation (AF) than those in Non-PPI group,P<0.05. The overall PPI occurrence rate was 3.07% after valve replacement and the short term incidence rate (within 30 days) was 0.55%, midterm (from 30 day to 1 year) was 0.03%, long term (>1 year) was 2.22%. For PPI indications, there were 70.5% patients with high degree A-V block including 30 of AF combining long intervals, 12 of high degree A-V block, 1 of complete left bundle branch block (LBBB) and 14.8% patients with sick sinus syndrome/sinus arrest/ sinus bradycardia. Conclusion: PPI incidence was at a relative low level, the long term occurrence rate was higher than both short term and midterm; elder age, pre-existing AF could be the high risk factors for PPI requirement, and the major PPI indication was high degree AV block in clinical practice.

Objective To explore the influence of different administration time on antidepressant effect of seven clinical common antidepressants. Methods Male mice were randomly divided into eight groups:venlafaxine (75 mg/kg), sertraline (20 mg/kg), fluoxetine (20 mg/kg), doxepin (15 mg/kg), mirtazapine (15 mg/kg), citalopram (40 mg/kg), trazodo?ne (50 mg/kg) and control (saline) groups. Each group contained 36 mice. Drugs were administered to 6 mice per group 30 min before forced swimming test at the 6 time points (9:00, 13:00 and 17:00 as light phase and 21:00, 1:00 and 5:00 as dark phase). Forced swimming test was applied to determine the influence of dosing time on anti-immobility effect of seven antidepressants at each time point. Results Immobility time in venlafaxine group and sertraline group significant?ly decreased compared with that of control group at all time points(all P<0.05). Moreover, anti-immobility effects of ven?lafaxine, fluoxetine, mirtazapine and doxepin were better during the dark phase than during the light phase (all P<0.05). In addition, immobility time in sertraline group decreased at the late part of dark phase (5:00) and the early part of light phase (9:00) compared with other phases (P<0.05). Conclusions Most antidepressants show 24-h rhythm dependent an?ti-immobility effects, but rhythmic patterns are not completely consistent among different antidepressants. Further study is needed to explore the chronopharmacological mechanism and clinical applications of these antidepressants.

Objective The aim of this study was to explore the inhibitory effect of alcohol extracts of Narcissus bulb on melanogenesis in zebrafish embryos.Methods Zebrafish embryos were exposed to different concentrations of alcohol extracts of Narcissus (0, 50, 100, 200, and 500 μg/mL), and then the formation of melanin was observed.Furthermore, we measured the enzyme activity of tyrosinase (TYR), which plays a pivotal role in melanogenesis.Meanwhile, the spatial and temporal pattern of melanin-specific marker genes were detected.Arbutin (Ar) was used as a positive control in all these experiments.Results The treatment of alcohol extracts of Narcissus bulb inhibited melanogenesis in the zebrafish embryos in a dose-dependent manner.Furthermore, the mRNA expression levels of melanin-related genes such as tyrosinase (TYR), silver (SILV) and Mitfa were significantly reduced after treatment with different concentrations of Narcissus extracts by in-situ and semi-quantitative PCR.Finally, the enzyme activity of tyrosinase was also gradually decreased with increasing concentrations of the alcohol extracts.Conclusions Narcissus alcohol extracts can effectively inhibit the production of melanin in zebrafish embryos.This study provides potential evidence and approaches for the screening of natural whitening compounds using zebrafish models.

Objective To evaluate the influence of the CT enterography (CTE) in different scan phases of small intesti?nal wall and arteriovenous vessels, and to confirm the diagnostic efficiency thereof. Methods A total of 286 patients under?went CTE were collected, and their CT image of three scan phases, including 20 s, 40 s and 60 s after injection, were record?ed. Values of reinforcement of the intestinal wall and arteriovenous enhancing degree in all phases were collected. A statisti?cal analysis was used to confirm the best phase for showing the structure. The diagnostic efficiency of the best phase of CT image was evaluated for the clinical diagnosis of small intestine and vascular lesions. Results (1) The CT value of the small intestinal wall in the intestinal phase was significantly higher than other two phases (P<0.05). There was no significant dif?ference in CT value between arterial phase and portal phase. (2) Comparison between three phases of CT values of ileum showed that artery:arterial phase>intestinal phase, and there is no statistical difference between the intestinal phase and oth?er two phases. The result of CT value of ileum vein showed that intestinal phase>portal phase>arterial phase (P<0.05). (3) The sensitivity was 95.8%, the specificity was 94.9%, the accuracy was 95.1%, the positive predictive value was 79.3%and the negative predictive value was 99.1%using CT image of intestinal period for diagnosing small intestinal diseases. (4) The intestinal period showed small intestinal lesions and confirmed by pathology including 22 cases of small intestinal lympho?ma, 10 cases of stromal tumor, 1 case adenoma, cavernous 3 cases hemangioma and 8 cases of Crohn's disease. The diagno?sis of hemangioma should be combined with arterial phase. Conclusion Small intestinal wall and blood vessels have better display performance in the intestinal phase of multiphase CT enterography, using the arterial phase and intestinal phase scan?ning, we can make an accurate diagnosis for the majority of small intestinal diseases.

OBJECTIVETo analyze the effects of acupuncture on the level of atrial natriuretic peptide (ANP), C-type natriuretic peptide (CNP) in adrenal gland and the content of corticosterone (CORT) in plasma in rats withchronic emotional stress anxiety, and to explore the partial action mechanism of acupuncture on anxiety disorder.

METHODSThirty-two healthy Sprague-Dawley (SD) rats, after 7 days of feeding and domestication, were randomly divided into a blank group (10 rats), a model group (11 rats) and an acupuncture group (11 rats). The rats inthe model group and acupuncture group were treated with unpredictable chronic emotional stress (CES) method toestablish the model of anxiety. Rats in the acupuncture group were treated with acupuncture at "Neiguan" (PC 6)and "Shenmen" (HT 7), once every other day, 30 minutes each time. The model establishment and treatment lasted 15 days. Rats in the blank group were treated with identical immobilization but no treatment was given. Theelevated plus maze was used to test the behavioral changes of rats with anxiety; the level of CORT in plasma wasdetected by ELISA, and the expression level of CNP and ANP in adrenal cortex and medulla was detected by immunohistochemical method.

RESULTS(1) The percentage of open-arms time in total time (OT%) in elevated plus maze in the model group was significantly lower than that in the blank group (P<0. 05); the OT% in the acupuncture group was significantly higher than that in the model group (P<0.01). (2) The content of CORT in plasma in the model group was higher than that in the blank group (P<0. 05), while that in the acupuncture group was significantly lower than that in the model group (P<0. 05). (3) The expression of ANP in adrenal medulla and cortex in the model group was lower than that in the blank group (P<0. 01), while the expression of CNP in adrenal medulla and cortex in the model group was higher than that in the blank group (P<0. 01).

CONCLUSIONThe effects of acupuncture against anxiety are likely to be related to the regulation on the expression of ANP and CNP in adrenal medulla, affecting the release of CORT and inhibition on the activity !f hypothalamic-pituitary-adrenal axis (HPA axis).

Objectives: To evaluate the predictor and risk factor of left ventricular (LV) free wall reverse remodeling in patients with obstructive hypertrophic cardiomyopathy (HCM) after modiifed Morrow procedure by three-layer speckle tracking of echocardiography.
Methods: Our investigation included 2 groups: HCM group, n=60 patients who had successful modified Morrow procedure in our hospital from 2014-06 to 2014-12, there were 41 (68.3%) male with the average age of (39.1 ± 15.2) years. Control group, n=40 healthy subjects. Three-layer speckle tracking echocardiography was conducted to analyze pre-and post-operative LV free wall three-layer myocardium (endocardial, mid, and epicardial layers) changes at longitudinal strain (LS) and circumferential strain (CS). Clinical and echocardiography information were collected at pre-and (6-24) months post-operation. The impact factors for LV free wall reverse remodeling was identiifed by liner regression analysis and the segment’s thickness≥15mm was deifned as the hypertrophic LV free segment.
Results: In HCM group, compared with pre-operative condition, the post-operative thickness of LV free wall including anterior, anterolateral and inferolateral were reduced;while both post-operative LS and CS elevated (-13.8 ± 4.8)%vs (-17.0 ± 5.2)%and (-23.7 ± 3.8)%vs (-25.4 ± 3.7)%, P<0.05. LV mass index by echocardiography was larger than LV mass index by surgical resection (13.5 ± 30.9) g/m2 vs (3.4 ± 2.0) g/m2, P<0.05. Liner regression analysis indicated that the number of pre-operative hypertrophic segments (r=-0.680, P<0.001) and age (r=0.638, P<0.001) were the independent impact factors for post-operative LS;△left ventricular outlfow tract (LVOT) gradient (r=0.386, P=0.005) was the independent impact factor for post-operative CS.
Conclusion:①After modiifed Morrow procedure, LVOT obstruction disappeared which leaded LV free wall reverse remodeling in HCM patients, ②three-layer myocardium of LV free wall all had reverse remodeling, ③better improved LVOT gradient were with less number of hypertrophic segments;the elder patients usually had the better post-operative reverse remodeling.

OBJECTIVE: To investigate the association between health related quality of life (HRQoL) and severity of depression in patients with major depressive disorder (MDD). METHODS: Short Form 36 Health Survey Questionnaire (SF-36) was administered to 103 MDD patients at the baseline and 6-week follow-up. Hamilton Depression Rating for Depression (HAMD) and Clinical Global Impression (CGI) were administered at the baseline, 2- and 6-week follow-up, respectively. RESULTS: All SF-36 component scores in the 6-week follow-up were significantly higher than those at the baseline (P<0.01). The overall and subscale scores of HAMD except weight and CGI scores at the 2- and 6-week follow-up were significantly lower than those at the baseline (all P<0.01). The role-emotion score of the clinical remission group was significantly lower than that of the non-remission group. After a 6-week antidepressant treatment, all SF-36 component scores in both groups were significantly higher than those at the baseline, except body pain in the non-remission group. While scores of role-physical, general health, vitality, social functioning, role-emotion and mental health were significantly higher in the remission group than those in the non-remission group (P<0.05 or P<0.01). A higher overall score of HAMD, scores of cognitive disturbance and CGI were significantly associated with a worse SF-36 at the baseline (P<0.05 or P<0.01). After the 6-week treatment, a worse health transition was significantly associated with higher scores of HAMD and sleep disturbance at the baseline (P<0.01), a worse general health and role-emotion were strongly associated with higher score of anxiety/somatization at the baseline (both P<0.05). Score of general health was positively associated with reduction rate of cognitive disturbance at the 2-week endpoint (P<0.05) and scores of vitality and reported health transition were positively associated with the reduction rate of sleep disturbance at the 2-week endpoint (both P<0.05). CONCLUSION The increasing severity of depression was significantly associated with a worse HRQoL in patients with MDD. A 6-week antidepressant treatment may result in comparable HRQoL improvements. The components of HRQoL vary with severity of various symptoms of depression at the baseline and their early improvement after the treatment.
