Hyperhomocysteinemia is an independent risk factor for arterial and venous obstructive vascular di-seases. Raised plasma homocysteine concentrations are caused by genetic and non-genetic factors. The pathogenic mechanism is not clear. It may be associated with endothelium dysfunction, abnormal lipid metabolism, hypertrophy of intima media, increased platelet aggregation and several clotting factors interfered, etc. The metabolism and pathogenic mechanism of homocysteine are reviewed in this article, which provides theoretical foundation for the treatement of hyperhomocysteinemia.

Objective To investigate the influence of anti-depression therapy on inflammatory cytokines and quality of life(QOL) in patients with acute coronary syndrome(ACS) complicating depression.Methods Ninety-four patients with ACS complicating depression(HAMD total score ≥8) were randomly divided into the treatment group and control group,47 cases in each group.The control group was given the conventional drug therapy,pantoprazole 40 mg /d,on this basis the treatment group was given sertraline 50 mg/d.The treatment course in the two groups was 6 months.The change of HAMD score,inflammatory cytokines,QOL and incidence of adverse cardiovascular events were observed and compared between the two groups.Results The HAMD score after 3-,6-month treatment in the treatment group was significantly lower than that in the control group (P<0.05).The levels of inflammatory cytokines after treatment in the two groups were all reduced,while the IL-6 and TNF-α levels in the treatment group were lower than those in the control group (P<0.05);the scores of all dimensions and total scores of SAQ after 6-month treatment in the treatment group were significantly improved,and the anginal attack situation,treatment satisfaction degree and total score were significantly higher than those in the control group (P<0.05).During 12-month follow-up,the incidence rate of major and minor cardiovascular events,alimentary tract hemorrhage events and total events had no statistical difference between the two groups(P>0.05).Conclusion The antidepressant therapy is safe and effective for treating ACS patients,can effectively improve the depression emotion,inhibits inflammatory reaction,relieves somatic symptoms,and improves QOL.

Objective To explore the evaluation value of modified USA National Institutes of Health Stroke Scale (mNIHSS) score combined with bedside transcranial Doppler ultrasonography (TCD) on the early prognosis of ischemic stroke (AIS).Methods One hundred and thirty-six anterior circulation AIS patients were collected,mNIHSS score was evaluated on admission,and emergency bedside TCD examination was performed to evaluate vascular anomalies.After active treatment after discharge,the modified Rankin scale (mRS) score was recorded to evaluate 90 d prognosis.The value of mNIHSS score combined with TCD examination analysis on the prognosis was analyzed.Results If the mNIHSS score > 8 scores was judged to be poor prognosis,the sensitivity was 0.684,the specificity was 0.806,the positive predictive value was 0.578,the negative predictive value was 0.868.If related macro vascular abnormalities in bedside TCD examination were evaluated for clinical prognosis,the sensitivity was 0.736,the specificity was 0.643,the positive predictive value was 0.444,the negative predictive value was 0.863.If both,the specificity was 0.918,the positive predictive value was 0.714,the positive likelihood ratio was 6.41 ;and the two were not available,the negative predictive value was 0.928,negative likelihood ratio was 0.20.Conclusion mNIHSS score combined with TCD examination in evaluating the prognosis of AIS patients can improve the positive or negative predictive value.

Objective To prepare novel alkanethiol modified magnetic silver flower nanoparticles as SERS substrate to chloramphenicol for Raman detection and to determine their enhancement effect.Methods An alkanethiol was chosen as a surface modifier of the substrate and was self-assembled onto the magnetic silver flower nanoparticle surface.The chloram-phenicol molecules were enriched to the surface of the substrate by hydrophobic interaction and the effect for detection of chloramphenicol SERS signal was enhanced.Results It was found that the 1-hexanethiol-modified SERS substrate was able to lead to stronger enhancement than 1-dodecanethiol and octadecanethiol.Fe3 O4@SiO2-Ag-C6 was used to detect the chloramphenicol (10 -3 -10 -10 mol/L) and chloramphenicol in milk (10 -3 -10 -9 mol/L) by surface-enhanced Raman spectroscopy.The detection limits were 0.1 nmol/L (32 ppt) and 1 nmol/L (323 ppt) respectively.Conclusion Alkanethiol modified magnetic silver flower nanoparticles are a highly active SERS substrate, which can be used for detection of low concentrations of analytical substances.

Column chromatography on silica gel was used to study the chemical constituents of traditional Chinese medicine Siegesbeckia pubescens. The chemical structures of the separated compounds were elucidated by spectroscopic data analyses. As a result, eighteen compounds were obtained and identified as 3, 4'-dimethoxy quercetin(1), 3, 3', 4'-trimethoxy quercetin(2), 3, 3'-dimethoxy quercetin(3), 7, 3', 4'-trimethoxy luteolin(4), ursolic acid(5), 2β,19α-dihydroxyursolic acid(6), 2β-hydroxyursolic acid (7), stigmasterol-7-one(8), 5α, 8α-epidioxy-24(R)-methyl-cholesta-6, 22-diene-3β-ol(9), β-sitosterol(10), 2, 6-di(3-hydroxy-4-methoxyphenyl)-3, 7-dioxacyclo [3. 3. 0] octane (11), aurantiamide acetate (12), 3-(m-hydroxyl-p-methoxy)-N-(2'-p-hydroxyl-phenethyl)-2E-acrylamide(13), p-hydroxy benzaldehyde (14), m-hydroxy-p-methoxy benzaldehyde (15), 3, 4, 5-trimethoxybenzoic acid(16), monoethyl malonate(17), and p-hydroxylcinnamic acid(18). Among them, compounds 1-9, 11-18 were isolated from this plant for the first time.

OBJECTIVETo perform a transcriptomics study in differential genes after Xianglian External Lotion (XEL) induced the recovery of drug-resistant Candida albicans strains sensitive to Fluconazole.
METHODSBroth microdilution antifungal susceptibility test was used to detect minimal inhibitory concentration (MIC) of drug-resistant Candida albicans strains induced by XEL. Transcriptome sequencing (RNA-Seq) was used to determine and compare the transcription of primary drug-resistant Candida aIbicans strains and sensitive strains induced by XEL. High expressed genes and signaling pathways strains were analyzed by gene ontology (GO) method.
RESULTSXEL could induce drug-resistant strains of the 6th generations to recover sensitivity. Transcriptome sequencing showed that, as compared with primary drug-resistant strains, there were 165 genes with up-regulated RPKM index and 144 genes with down-regulated RPKM index after XEL induction. GO analyses found that all genes were mainly classified as GO:0015903 (fluconazole transport).
CONCLUSIONSXEL could induce the recovery of drug-resistant Candida albicans strains sensitive to Fluconazole. By analyzing transcriptomes, authors speculated that XEL could recover strain sensitivity to fluconazole by opening fluconazole transport pathway.

Objective To investigate the feasibility and value of CT perfusion imaging in combination of CTA 320-slice CT with dual-low-dose in detection of acute cerebral ischemia.Methods Forty patients with acute stroke underwent perfusion imaging and CTA using a single scan with 320-slice CT with dual-low-dose schedule.CTA,4D-CTA,4D-perfusion imaging and fusion images were generated at a post-processing workstation.All patients also underwent a 3.0T magnetic resonance imaging with DWI for a comparison.Quality of the images,degree of vascular stenosis,and location of ischemic lesions were evaluated.Results The vascu-lar stenosis or occlusion was found in 33 patients,8 of whom were confirmed by the DSA.The ratio of better images of CTA was 82.5%.CTP showed 297 lesions with abnormal perfusion.202 lesions were confirmed as infarct by DWI,while 95 ones were nor-mal on DWI but with increased DLY and TTP and slightly decreased CBF and CBV in 49,increased DLY and TTP and normal CBF and CBV in 21,and increased DLY and TTP and slightly increased CBF and CBV in 25.Conclusion CT perfusion in combination with CTA by 320-slice CT with dual-low-dose is feasible and useful to observe accurately the vascular structures and the ischemic status of the whole brain at early stage.
