Objective To explore the clinical application value of combined detection of serum brain natriuretic peptide (BNP),homocysteine(HCY) and blood lipids in the patients with heart failure.Methods The levels of serum BNP,HCY,TC,TG,HDL-C,LDL-C,ApoA,ApoB and Lpa were detected in 100 patients with heart failure (observation group) and contemporaneous 100 persons (control group) undergoing healthy physical examination.Then the comparative analysis was performed.Results Compared with the control group,the BNP and HCY levels in the observation group were significantly increased(P<0.05);among 7 indicators of the blood lipid,the Lpa level in the observation group was increased compared with the control group,while the TC,HDL-C and LDL-C levels were significantly decreased(P<0.05),and the TG,ApoA and ApoB levels had no statistical differences between the two groups(P>0.05).Conclusion Serum BNP,HCY,TC,HDL-C,LDL-C and Lpa levels have close correlation with heart failure,especially the combined detection of BNP,HCY and Lpa,which has predictive and diagnostic value in heart failure and is worthy of clinical popularization and application.

Objective To analyze the VP1-VP4 genetic region of enterovirus 71 ( EV71 ) strains isolated from children with severe or mild hand, foot and mouth disease ( HFMD) in Shenzhen in 2012. Methods EV71 strains were isolated from five children with mild HFMD and five children with severe HFMD in Shenzhen in 2012.Reverse transcription-polymerase chain reaction ( RT-PCR) method was used to amplify the sequence of VP1-VP4 genes of EV71 strains.The sequences of the amplified products were analyzed by comparing with those of the EV71 reference strains ( A, B and C genotypes) published in Gen-Bank using nucleotide alignment, amino acid alignment and phylogenetic tree analysis.Results The homo-geneity between the EV71 strains isolated from severe and mild cases was 95.1%-98.2% in nucleotides and 99.2%-100% in amino acids.The VP1-VP4 nucleotide sequences of 5 strains isolated from severe cases and 5 strains from mild cases in Shenzhen shared 87.9%-97.8% homologies in nucleotides and 97.3%-99.9% homologies in amino acids with the genotype C EV71 reference strain.The EV71 strains isolated from children in Shenzhen were highly similar with the EV71 strain (FJ439769) isolated in Fuyang in 2008 and the one isolated in Jingdezhen in 2011 (JQ806378, C4a subtype) in nucleotide sequences.Mutations at the residue 31 in the VP1 region ( N→D ) were detected in 3 strains isolated from children with severe HFMD.Conclusion All of the 10 EV71 strains isolated in Shenzhen in 2012 belonged to the sub-genotype C4a.The mutation ( aa31 N→D) in the VP1 region of EV71 might be related to the different clinical mani-festations of HFMD cases in Shenzhen area.

Flocculent gene FLO1 and its truncated form FLO1c with complete deletion of repeat unit C were expressed in a non-flocculent industrial strain Saccharomyces cerevisiae CE6 to generate recombinant flocculent strains 6-AF1 and 6-AF1c respectively. Both strains of 6-AF1 and 6-AF1c displayed strong flocculation and better cell growth than the control strain CE6-V carrying the empty vector under acetic acid stress. Moreover, the flocculent strains converted glucose to ethanol at much higher rates than the control strain CE6-V under acetic acid stress. In the presence of 0.6% (V/V) acetic acid, the average ethanol production rates of 6-AF1 and 6-AF1c were 1.56 and 1.62 times of that of strain CE6-V, while the ethanol production rates of 6-AF1 and 6-AF1c were 1.21 and 1.78 times of that of strain CE6-V under 1.0% acetic acid stress. Results in this study indicate that acetic acid tolerance and fermentation performance of industrial S. cerevisiae under acetic acid stress can be improved largely by flocculation endowed by expression of flocculent genes, especially FLO1c.

Objective To investigate the application value of DWI based on biexponential signal decay model with extended b-fac-tor range in differential diagnosis of benign and malignant breast lesions.Methods A total of 57 patients with breast tumor under-went DWI based on the biexponential model with 12 b-factors (0,10,20,50,100,200,400,600,800,1000,1 200 and 1 500 s/mm2 ), including benign lesions in 1 9 patients (24 breast tumors,defined as benign group)and malignant ones in 38 (47 tumors,defined as malignant group ).The values of slow apparent diffusion coefficient,fast apparent diffusion coefficient and fraction of fast ADC of le-sions were measured at a workstation (Advantage Windows 4.5).Differences in these parameters between the benign and malignant groups were compared.Results The ADCslow,ADCfast and ffast were(1.434±0.291)×10 -3 mm2/s,(2.744±0.050)×10 -3 mm2/s and (0.677±0.130)% in benign group,and (0.614±0.196)×10 -3 mm2/s,(2.692±0.068)×10 -3 mm2/s and (0.446±0.112)% in malig-nant one,respectively.The statistical differences in ADCslow and ffast were found between two groups (P <0.05),whereas no difference in ADCfast was found.Conclusion Biexponential signal decay model of DWI with extended b-factor range can provide helpful tissue characterization parameters for the differential diagnosis of benign and malignant breast lesions.

AIM: To observe the effect of continuous epidural analgesia (CEA) of tramadol on postoperative gastrointestinal function and serum motilin level in the patients with cholecystectomy. METHODS: Twenty eight ASAⅠ-Ⅱpatients (8 male, 20 female) aged 24-56 yr, scheduled for elective cholecystectomy under epidural anesthesia, were randomly divided into tramadol group (T, n=14) and control group (C, n=14). The combination of tramadol 800 mg+ bupivacaine 150 mg+ droperidol 5 mg, which diluted with normal saline to 100 ml and pumped 2 ml?h -1, was administered in group T. The combination in group C was bupivacaine 150 mg+ droperidol 5 mg. The VAS values, the first anorectum exhaust timing (FAET), and the time of the first eliminating stool timing (FEST) were recorded, and serum motilin level measured with radioimmunoassay at the different times after surgery. RESULTS: There was a significant difference in the mean VAS values between group T ( 1.2? 1.2) and group C ( 3.3? 1.3) (P

Objective:To observe the effects of sera Th1/Th2-typed cytokines in patients allergic rhinitis (AR) who were treated with kebimin decoction(KD),and to study the therapeutic mechanism of KD in AR.Methods:60 patients of AR were randomly divided into two groups (treating group,TG and control group,CG). Patients in TG were treated with KD,while those in CG were treated with Xinfang Rhinitis Capsule before and after treatment,the levels of serum Th1-typed cytokines IFN-?、IL-2、IL-12 and Th2-typed cytokines IL-4、IL-5、IL-10 were determined by enzyme-linked immune sorbent assay (ELISA); and compared with 30 healthy controls.Results:The levels of serum Th2-typed cytokines IL-4、IL-5、IL-10 were higher and the levels of Th1-typed cytokines IFN-?、IL-2、IL-12 were lower in AR than that in healthy control ( P 05).Conclusion:Kebimin decoction is highly effective in treating allergic rhinitis by regulating the levels of Th1、Th2-typed cytokines,correcting the imbalance Th1/Th2-typed cytokines network.
