Objective To investigate the therapeutic effect of tumor necrosis factor (TNF)-αsiRNA on typeⅡcolla-gen induced arthritis (CIA) in rats. Methods The expression vectors of siRNA against TNF-αgene were constructed suc-cessfully and were injected by tail veil into CIA rats. Twenty-four CIA rats were randomly divided into 4 groups including model group, empty vector group, TNF-α-siRNA1 group and TNF-α-siRNA2 group. CIA rats were injected with the same dose of phosphate buffered sodium (PBS) and pGFP-V-RS vector respectively in model group and empty vector group, while TNF-α-siRNA1 group and TNF-α-siRNA2 group were injected with TNF-α-siRNA1 eukaryotic expression vector and TNF-α-siRNA2 eukaryotic expression vector respectively. Another 6 rats, which were not established CIA model, were in-jected with PBS (blank control group). The serum expression levels of IL-1 were detected by ELISA on day 1, 5, 9 and 13 af-ter injection. The expression level of TNF-αmRNA was detected by reverse transcriptase polymerase chain reaction (RT-PCR) on day 13. Results The expression level of IL-1 was significantly higher on day 1, 5, 9 and 13 in model group than that of blank group (P＜0.05). The expression levels of IL-1 were significantly lower on day 1, 5 and 9 in TNF-α-siRNA1 group and TNF-α-siRNA2 group than that of model group and blank group (P ＜ 0.05). The expression level of TNF-αmRNA was significantly higher on day 13 in model group than that of blank group (P＜0.05). The expression levels of TNF-αmRNA were significantly lower in TNF-α-siRNA1 group and TNF-α-siRNA2 group than those of model group and emp-ty vector group (P＜0.05). Conclusion TNF-αspecific siRNA can suppress the levels of TNF-αmRNA and IL-1, which provides experimental basis for gene therapy of rheumatoid arthritis.

Background: Parkinson’s disease (PD) is a complex disorder that involves multiple genetic and environmental factors. Several candidate genes have been speculated to be involved in the development of PD. We conducted a case-control study to investigate the association between PD and single nucleotide polymorphisms (SNP) at the OPRM1, DAT, COMT and DRD2 genes in a Taiwanese population. Methods: The study included 260 PD cases and 100 healthy controls. SNPs at OPRM1 (rs1799971), DAT (rs2652510 and rs2550956), COMT (rs4680) and DRD2 (rs1800497) were determined by high-resolution melting (HRM) analysis using a LightCycler®480 instrument. Each genotype was confirmed by direct sequencing. The genotype was checked for Hardy-Weinberg equilibrium. Results: The chi-square test (χ2 ) was used to examine the association between SNP genotypes and PD. The OPRM1 (rs1799971), DAT (rs2652510 and rs2550956), COMT (rs4680) and DRD2 (rs1800497) polymorphisms showed no association with PD. Notably, an additional meta-analysis indicated that DAT rs2652510 was significantly associated with PD risk. Conclusions: In the Taiwanese population the frequency of the OPRM1, DAT, COMT, and DRD2 genotypes exhibits no difference between the PD patients and normal controls. The meta-analysis of the original and available data from published studies resulted in significant p values <0.01 for DAT rs2652510.

Objective To explore the clinical significance of dyslipidemia in patients with systemic lupus erythematosus (SLE).Methods By independent-samples t test,serum lipid level was compared between 326 SLE patients and 300 healthy controls.The total cholesterol (TC),triglyceride (TG),lowdensity lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were partially compared in subgroups of SLE patients.The correlation of serum TC,TG,LDL-C and HDL-C with clinical manifestations and laboratory findings in SLE was analyzed by Pearson or Spearman correlation analysis.Results ①The serum levels of TC [(3.8±1.5) mmol/L],TG [(2.1±1.6) mmol/L] and LDL-C [(2.1±0.9) mmol/L] were significantly higher in SLE group than those of the control group [(3.4±0.6),(0.8±0.4),(1.9± 0.5) mmol/L],and the serum level of HDL-C [(1.2±0.9) mmol/L] was significantly lower in SLE group than that of the control group [(2.0±0.5) mmolFL] (t=4.953,P=0.000; t=14.569,P=0.000; t=3.204,P=0.001; t=-14.335,P=0.000].② The serum levels of TC [(4.0± 1.7) mmol/L],TG [(2.5± 1.7) mmol/L] and LDL-C [(2.2±1.0) mmol/L] were significantly higher in LN group than those of the non-LN group [(3.6±1.0),(1.6± 1.0),(1.9±0.7) mmol/L; t=2.646,P=0.009; t=6.292,P=0.000; t=3.261,P=0.001].③ The serum level of TG [(2.2±1.6) vs (1.8±1.4) mmol/L] was significantly higher in SLE patients with hypocomplementemia than that of the normal ones (t =2.098,P=0.038).The serum level of HDL-C [(1.1 ±0.4) vs (1.6± 1.7) mmol/L] was significantly lower in SLE patients with hypocomplementemia than that of the normal ones (t=-2.375,P=0.020).④ The serum level of TG [(2.3±1.7) vs (2.0±1.4) mmol/L] was significantly higher in anti-dsDNA antibody positive patients than that of negative ones (t=1.989,P=0.048).The serum level of HDL-C [(1.5± 0.4) vs (1.4±1.2) mmol/L] was significantly lower in anti-dsDNA antibody positive patients than that of negative ones (t=-2.979,P=0.003).⑤ The lipid level was correlated with the clinical manifestations and laboratory findings in SLE patients.Conclusion Dyslipidemia exists in patients with SLE and has close correlation with LN,hypocomplementemia and positive anti-dsDNA antibody.

Objective To make the identification of medicinal herbs in Salvia L. quickly and accurately. Methods In this work,DNA barcoding and chemical fingerprint were compared for the identification of herbs in Salvia L. First, the nucleotide sequences of the internal transcribed spacer region two amplified from 48 medicinal plants in Salvia L., and three other groups of medicinal plants in Lamiaceae were sequenced. A molecular phylogeny was constructed using the minimum evolution and maximum parsimony methods according to their sequence diversity. Second, the water-solution bioactive components and lipid soluble components were tested by HPLC. Then a chemical phylogeny was built using HPLC fingerprint data. Comparing the molecular and chemical phylogenetic trees revealed many similarities. Results DNA barcoding was sequencing based and could therefore provide more accurate results within a shorter time especially in large-scale studies. Conclusion The results show that ITS2 region is a novel DNA barcode for the authentication of the species in Salvia L. This is the first work to show the relationship between DNA barcoding and chemical components.

Objective To investigate prevalence of erectile dysfunction(ED)in type 2 diabetic male patients and to analyze its related factors.Methods A total of 904 married male patients with type 2 diabetes were involved in this study and they were interviewed with anonymous questionnaire.An international index of erectile function-5(IIEF-5)was used to determine the severity of ED by self-rating score in age,duration of diabetes,serum level of glycosylated hemoglobin A1c(HbA1c),history of alcohol drinking and smoking,blood pressure and anti-hypertensive medication in diabetic ED patients.Relationship between relevant factors and diabetic ED was analyzed.Results ED was diagnosed in 612 diabetics with prevalence of 67.7 percent(612/904)according to their total scores of IIEF-5.Logistic regression analysis showed that increase in duration of diabetes by five years,age by 10 years,serum level of HbAI c by 2%, systolic blood pressure by 30 mm Hg(1 mm Hg = 0.133 kPa),positive history of smoking and alcohol drinking were all independently associated with prevalence of diabetic ED,with OR of 1.96,1.25,2.32, 1.12,1.67(P

Objective To investigate the differentiatial diagnostic value of 99Tcm-methoxyisobutylisonitrile ( MIBI ) SPECT combined with localizable CT in the evaluation of oxygen intervention for suspicious lung lesions,and to establish a cost-effective imaging modality in the detection of malignant lung lesions.Methods From September 2008 to March 2009,47 consecutive patients with suspicious malignant lung lesions underwent 99Tcm-MIBI SPECT/CT prospectively. Patients with suspicious pneumonia were treated with antibiotics for about 4 d before imaging. All patients were cannulized with a nostril tube for oxygen inhalation before 99Tc-MIBI injection. SPECT combined with localizable CT of the chest was performed at 10 min and 2 h after 99Tcm-MIBI injection. The uptake ratios of lesion to contralateral normal lung parenchyma(early uptake ratio:EUR and delayed uptake ratio:DUR) were compared using independent-samples ttest. In addition,the diagnostic efficiency of uptake ratios of lung lesions was analyzed with receiver operating characteristic (ROC) curve. Results Forty-seven patients ( primary lung cancers:32,metastatic tumors of the lung:4,benign lung diseases:11 ) had 51 lung lesions,including 39 malignant and 12 benign lung lesions. The sensitivity,specificity,accuracy,positive predictive value (PPV),and negative predictive value (NPV) were 94.9% (37/39),83.3% ( 10/12),92.2% (47/51),94.9% (37/39) and 83.3% ( 10/12),respectively. The EUR of malignant lesions was 2.95 ± 1.16,whereas of benign lesions was 1.43 ±0.33. The DUR of the malignant lesions was 3.19 ± 1.74,whereas of benign lesions was 1.60 ±0.32. Both EUR and DUR were significantly different between malignant and benign lung lesions,respectively (t= -4.44,-3.12,respectively,both P＜0.01). The ROC curve showed that EUR value ≥1.625 provided the sensitivity of 97.4% (38/39) and specificity of 83.3% (10/12); DUR value ≥ 1.75provided the sensitivity of 94.9% (37/39) and specificity of 83.3% (10/12). Conclusion 99Tcm-MIBI SPECT combined with localizable CT imaging in oxygen intervention has a potential value in differentiating malignant from benign lung lesions.
