Objective: To investigate the effects of human tissue inhibitor of matelloproteinase 4 (TIMP 4) on vascular smooth muscle cells (VSMCs) migration and the neointimal formation after balloon injury in rats. Methods: The cultured VSMCs were transfected with an adenoviral vector containing human TIMP 4 gene, AdTIMP 4. Effect of TIMP 4 on VSMC migration was investigated by monolayer cell scrape. AdTIMP 4, control adenoviral vector or PBS was transduced into the rat carotid artery from the adventitial after carotid artery injury. Cell number within the internal elastic lamina 4 days after gene transfer was counted and neointima/media area ratio 28 days after gene transfer was calculated. Results: The migration distance of VSMCs infected with AdTIMP 4 was inhibited markedly. Morphometric analysis demonstrated a statistically significant reduction in the number of cells migrated into neointima compared with controls [(32.5?4.8) cells per section, (33.8?7.0) cells per section and (8.2?2.4) cells per section for uninfected, AdGFP treated and AdTIMP 4 treated arteries, respectively]. There was a reduction of intima/media ratio of TIMP 4 treated group by 66.5% compared with control groups 28 days after gene transfer ( P

Objective To discuss the key points of endovascular therapy for complex subclavian artery occlusive diseases. Methods During the period from January 2012 to December 2013, a total of 92 patients with complex subclavian artery occlusive disease were admitted to Xuanwu Hospital of Capital Medical University, Beijing, China. The clinical data were retrospectively analyzed. The features of the lesions, the success rate of endovascular therapy, the use of combined approaches, the relief of symptoms after treatment, etc. were evaluated. Results The complex subclavian artery occlusive diseases could be divided into three types. Type Ⅰ: long segment of the left subclavian artery was occluded; type Ⅱ: ostial stenosis or occlusion of the right subclavian artery; and type Ⅲ: subclavian artery stenosis or occlusion was associated with the ostial disorder of the vertebral artery, or the opening of vertebral artery was affected by the subclavian artery stenosis or occlusion. The technical success rate was 82.6%. Combination use of femoral artery and brachial artery approach was employed in 27.2% of patients, which had improved the technical success rate. After the treatment the symptom improvement rate was 81.6%. Conclusion Upper limb artery approach can improve the re-canalization rate of left subclavian artery with long segment occlusion, and can ensure the accurate positioning of stent at the site of right subclavian artery opening. During the procedure of endovascular intervention for subclavian artery occlusion disease, attention should be paid to the protection of the vertebral artery.

Endovascular aortic repair (EVAR) has been the main treatment means for abdominal aortic aneurysm.It has become an expert consensus that in the case of abdominal aortic aneurysm that is complicated by iliac aneurysm,the preservation of internal iliac artery is necessary because it can prevent the occurrence of gluteal muscle ischemnia,sigmoid ischemia,male sexual dysfunction and other complications.In recent years,with the continuous updating of the endovascular devices it has become possible to retain the internal iliac artery in the performance of EVAR.At present,the reconstruction of internal iliac artery in EVAR includes a variety of techniques,including intraluminal iliac branched device (IBD) technique,sandwich technique,common iliac artery covered-stent bell-bottom (BBT) technique,external iliac artery-internal iliac artery intraluminal shunt technique (reverse chimney technique),and spring coil embolism technique.This article aims to make a summary of all the above mentioned techniques.

Objective To investigate the influence factors of quantitative changes of dendritic cells (DC) in neonate born to HBsAg positive mother.Methods Sixty HBsAg positive mothers and their newborns were enrolled from the Third People's Hospital of Taiyuan from July 2011 to March 2012.The serum hepatitis B virus (HBV) markers and HBV DNA in mothers and newborns before vaccination were determined by chemiluminescence immunoassay (CLIA) and fluorescence quantitative polymerase chain reaction (PCR).The circulating frequencies of DC subsets were determined in the newborns by flow cytometry (FCM).The comparison of data was done by Mann-Whitney test and t test.The correlation analysis was done by Spearman rank correlation analysis and chi square test.Results Among 60 newborns,5 were HBsAg positive and HBV DNA negative.Among 60 HBsAg positive mothers,21 were HBeAg positive and 29 were HBV DNA positive.There was no significant quantitative difference of neonatal myeloid dendritic cells (mDC) and plasmacytoid dendritic cells (pDC) between intrauterine infection group and intrauterine non-infection group (Z=-0.535,P=0.59 and Z=-0.027,P=0.98,respectively).However,mother's HBeAg positive status was closely related with neonatal HBeAg positive status (Pearson contingency coefficient was 0.928,P＜0.01).The frequencies of mDC in newborns born to HBeAg positive mothers were significantly lower than those born to HBeAg negative mothers (0.60±0.57 vs 0.87±0.58; Z=-2.085,P＜0.05).However,there was no significant quantitative differences of mDC and pDC between newborns born to HBV DNA positive mothers and born to negative mothers (Z=-1.272,P=0.20 and Z=-0.806,P=0.42,respectively).The frequencies of pDC were significantly lower in newborns born to mothers with HBV DNA＞ 1 × 107 copy/mL compared to newborns born to HBV DNA negative mothers (0.30±0.18 vs 0.64±0.55; t=-2.996,P=0.005).Conclusions HBeAg positive status of mothers may reduce neonatal frequencies of mDC.Neonatal frequencies of pDC may be reduced when the mothers' HBV DNA loads are more than 1 × 107 copy/mL.

Objective To investigate the influence factors of non-responsiveness and lowresponsiveness to hepatitis B vaccine of infants born to hepatitis 1 surface antigen (HBsAg) positive mothers.Methods A total of 219 HBsAg positive mothers and their full-term neonates were selected from July 2011 to December 2012 in the Third People's Hospital of Taiyuan.Serologic hepatitis B virus (HBV) markers and HBV DNA load of mothers and their neonates were determined.Neonates were followed up for 12 months to observe the effect of HBV intrauterine infection,hepatitis B e antigen (HBeAg) status,sex,delivery mode,feeding option and suffering from infectious disease during followup period on the immune response to hepatitis B vaccine.Chi-square test was used in univariate analyses and unconditional Logistical regression was used in multivariate analyses.Results There were 16 cases of non-responsiveness and 33 cases of low-responsiveness in all 219 neonates.The rate of non-responsiveness and low-responsiveness was 22.37 ％.In univariate analyses,neonatal HBeAg positivity (x2 =4.895,P=0.027),natural birth (x2 =5.210,P=0.022),suffering from infectious diseases during follow-up period (x2 =4.329,P=0.037) were significantly associated with non-responsiveness and low-responsiveness.There was no relationship between mother HBeAg positivity and the level of response to hepatitis B vaccine.In multivariate analyses,natural birth (OR=2.022,95 ％CI:1.045-3.914) and suffering from infectious diseases (OR=2.324,95 ％ CI:1.058-5.103) were associated with non-responsiveness and low-responsiveness.Conclusion Infants born to HBsAg positive mothers with natural birth or suffering from infectious diseases during follow-up period are more likely to be non-responsiveness and lowresponsiveness to hepatitis B vaccine.

Objective:To investigate the characteristics of implicit memory and its related factors in schizophrenic patients with negative and positive symptoms.Methods:Ninety-three schizophrenic patients (including 52 cases of negative symptoms group and 41 cases of positive symptoms group) and 30 normal controls (normal group) were tested with the method of Chinese character word completion method. The reaction time and correct rate were recorded and compared with analysis of variance and t-test, and the correlation with demographic factors was analyzed with Pearson correlation analysis. Results:Accuracy of implicit memory test in schizophrenia group: there were statistically significant differences in the accuracy of patients with different course of disease (≤5 years: (38±5)%, 5-15 years: (34±8)%, ≥15 years: (34±7)%, P<0.05).The differences were statistically significant in the accuracy of patients with different education levels(primary school: (35±6)%, junior and senior high school: (34±7)%, secondary college education and above: (39±5)%, P<0.05).The accuracy of patients with education years < 10 years ((34±7)%) was significantly lower than those with education years ≥10 years ((37±6)%, P<0.05).Reaction time results of implicit memory test in schizophrenia group : there were significant differences in reaction time of patients with different disease course(≤5 years: (3 248±971)ms, 5-15 years: (3 515±672)ms, ≥15 years: (3 925±842)ms, P<0.05).The differences were statistically significant in the reaction time of workers ((3 495±712)ms), farmers ((3 870±878)ms) and soldiers ((3 024±924)ms, P<0.05).The reaction time of patients with clozapine ((3 869±871)ms) was significantly higher than that of patients with olanzapine ((3 393±626)ms, P<0.05).Intergroup results of accuracy: the accuracy of normal control group ((40±5)%) was significantly higher than that of negative symptom group ((33±7)%, P<0.01).The accuracy of negative symptom group was significantly lower than that of positive symptom group ((37±6)%, P<0.01).Intergroup reaction time results: the reaction time of normal control group ((2 660±667)ms) was significantly lower than that of negative symptom group ((3 678±951)ms, P<0.01) and positive symptom group ((3 072±865)ms, P<0.05).The reaction time of negative symptom group ((3 678±951)ms)was significantly higher than that of positive symptom group( P<0.01).There was significant negative correlation between the accuracy of implicit memory and the course of disease in schizophrenia ( r=-0.22, P<0.05). Conclusion:The implicit memory of schizophrenic patients is related to the course of disease, taking drugs, and occupation.There may have differences in implicit memory between patients with negative and positive symptoms of schizophrenia.

OBJECTIVETo investigate the cost-effectiveness of fish oil in patients undergoing major surgery and those with systemic inflammatory response syndrome(SIRS).

METHODSA retrospective study was conducted in patients undergoing major surgery and those with SIRS on admission in the Zhongshan Hospital from January 2008 to December 2011. Fish oil group was enrolled and matched to control group by 1:2 for gender, age, diagnosis, and surgical procedure. There were 220 pairs of patients who were not admitted to ICU, 102 pairs of patients admitted to ICU, and 66 pairs of patients with SIRS. The clinical outcomes and costs were measured and cost-effectiveness analyses were conducted.

RESULTSThe clinical outcomes and costs showed no significant difference between the fish oil group and the control group in those patients who were not admitted to ICU(P>0.05). Fish oil fat emulsion supplementation significantly reduced the length of total hospital stay, postoperative hospital stay, ICU stay, re-operation rate, infection rates, perioperative mortality in patients admitted to ICU and those with SIRS(P<0.05). The cost-effectiveness ratio of non-reoperation rate, non-infection rate, and survival rate were lower in those patients receiving fish oil fat emulsion as compared with those without fish oil administration. Fish oil fat emulsion supplementation could reduce cost-effectiveness ratios of non-reoperation rate, non-infection rate and survival rate by 105 RMB, 160 RMB, and 89 RMB respectively in major surgical patients who admitted to ICU, and by 670 RMB, 280 RMB, and 220 RMB respectively in SIRS patients.

CONCLUSIONSAddition of fish oil fat emulsion to clinical nutrition may have positive effects on critically ill patients. It seems that the effects of fish oil fat are strongly related to the severity of patient's underlying disease. Fish oil fat emulsion supplementation shows acceptable cost-effectiveness ratio and pharmacoeconomic value.
