Objective To explore the levels and clinical significance of anti-beta 2-glycoprotein 1 antibodies (β_2GP1), matrix metalloproteinase 9 (M M P-9) in the plasma of children with Kawasaki diseases (KD). Methods Serum level of anti-β_2GP1 antibody and MMP-9 was measured in 47 children with KD by ELISA, and the data was analyzed using SPSS11.5 software. Thirty age matched children with infectious diseases(sepsis or pneumonia), exclusive of heart, liver, kidney, blood diseases and autoimmune diseases such as rheumatoid were chosen in the fever control group. Results Coronary artery lesions (CAL)were found in 17 children of KD group (17/47) by Doppler ultrasound examination. Significant differences (P < 0.05) of serum level of anti-β_2GP1 antibody was showed between KD group ((7.46 ± 2.13) U/ml)and the control group ((4.38 ± 0.43) U/ml) ; serum level of MMP-9 was (886.62 ± 92.72) ng/ml and (460.06 ± 179.59) ng/ml in KD group and the control group respectively, with significant difference between the two groups(P < 0.05). In KD group, levels of anti-β_2GP1 were (8.83 ± 0.89) U/ml among children with CAL and (6.18 ± 1.42) U/ml among children without CAL, serum level of MMP-9 was (948.62 ± 81.76) ng/ml and (872.00 ± 34.74) ug/ml respectively, with significant differences(beth P < 0.05). In children with KD, the serum levels of anti-β2GP1 antibody and MMP-9 were significantly correlated (correlation coefficient r = 0.665). Conclusions Serum levels of anti-β_2GP1 antibodies and MMP-9 increased in the acute phase of KD, and were significantly higher in those KD children with CAL.Anti-β_2GP1 antibodies and MMP-9 may play a role in the pathogenesis of KD, and can be used as an important serological indicator of KD with CAL.

Objective To determine the gene polymorphism and serum concentration of mannose-binding lectin (MBL) in patients with psoriasis,and to analyze the relationship between MBL and psoriasis.Methods Totally,67 patients with psoriasis vulgaris and 69 healthy human controls were enrolled in this study.Venous blood samples were obtained from all the subjects.Genomic DNA was extracted,and PCR-restriction fragment length polymorphism (PCR-RELP) analysis was conducted to determine the polymorphism at codon 54 of the MBL gene.Enzyme-linked immunosorbent assay was performed to measure the serum level of MBL.A chi-square goodness-of-fit test was carried out to evaluate Hardy-Weinberg equilibrium,t test to compare the serum concentration of MBL,and chi-square test to compare the frequency of genotypes and alleles of MBL gene codon 54.Results The patients with psoriasis showed higher frequency of GGC/GAC heterozygote but lower frequency of GGC/GGC homozygote (x2 =10.36,P ＜ 0.05),together with increased frequency of GAC allele but decreased frequency of GGC allele (x2 =8.31,P ＜ 0.05),at codon 54 of the MBL gene compared with the healthy controls.The variant allele GAC at codon 54 of the MBL gene was markedly associated with psoriasis (OR =3.383,95％ CI 1.585-7.211,P ＜ 0.05).The serum concentration of MBL was (2.193 7 ± 0.816 3) mg/L in patients with psoriasis,significantly lower than that in the healthy controls ((3.269 5±1.205 8) mg/L,t=6.11,P＜ 0.05).Conclusion MBL might be associated with the pathogenesis of psoriasis to some degree.

Objective To investigate the changes of serum immunoglobulin E(IgE)?T cell subgroups and cytokines in asthmatic children and to provide theoretical basis for the management of asthmatic children.Methods T cell subgroups were determined by indirect immuofluorence method mono clone antibody, the detection of IgE,interleukin(IL) 4,IL 6,IL 8,interferon ?(IFN ?) were done by ELISA method, and 20 normal children were served as control group.Results There were significant differences of CD3 +,CD4 +,CD4 +/CD8 + among the stages of exacerbation and convalescence of asthmatic children and control group.( P0.05).In the stage of convalescence the levels of IL 2,IFN ? were lower than control group( P0.05).Conclusions Allergic asthmatic patients between the exacerbation and convalescence stages still had immunologic imbalance,indicating increased number of CD4 +T cell(mainly Th2 cells)and hyperfunction;the insufficient number and(or) the inactivity of CD8 +T cell may induce immunological disturbance ,which is the major mechanism of asthmatic attacks. These findings suggest the patients in an abnormal immunological state should receive continuous anti allergic therapy.

Objective To investigate the expression of mannose-binding lectin (MBL) in lesions of patients with psoriasis vulgaris,and to explore the relationship between MBL and psoriasis pathogenesis.Methods Immunohistochemistry and Western blot were performed to detect the expression of MBL in lesional and normalappearing perilesional skin of 30 patients with progressive psoriasis vulgaris,as well as in normal skin of 30 healthy human controls.Statistical analysis was carried out by t test using SPSS13.0 software.Results Immunohistochemistry showed that MBL was expressed in lesional psoriatic skin,but weakly expressed or absent in normalappearing perilesional skin and normal control skin,with the relative expression level of MBL in lesional skin significantly higher than that in perilesional skin and normal control skin (0.636 7 ± 0.515 1 vs.0.416 3 ± 0.160 1 and 0.381 6 ± 0.310 9,t =2.24,2.32,respectively,both P ＜ 0.05).Western blot revealed a positive expression of MBL protein in all the skin specimens,and the expression intensity of MBL protein in lesional psoriatic skin was significandy increased compared with perilesional psoriatic skin and normal control skin (0.273 1 ± 0.129 4 vs.0.186 3 ± 0.193 1 and 0.149 2 ± 0.268 7,t =2.05,2.28,respectively,both P＜ 0.05).No significant difference was shown in the expression of MBL protein between perilesional psoriatic skin and normal control skin by immunohistochemistry (t =1.51,P ＞ 0.05) or Western blot (t =0.61,P ＞ 0.05).Conclusion There is a high expression of MBL protein in lesions of patients with psoriasis vulgaris,which may be somewhat associated with the pathogenesis of psoriasis.

A 56-year-old female patient of Han nationality presented with generalized erythema and vesicles for 6 days,as well as high fever for 2 days.Twenty days prior to hospitalization,the patient received surgical treatment combined with oral methazolamide and glucocorticoids for glaucoma.The patient had a history of allergy to sulfanilamides.On admission,the patient presented with generalized erythema,vesicles and occasional erosions with bilateral eyelid and oral involvement.Nikolsky's sign was positive.Wheezing sound was heard over the right lung.Genetic testing showed that HLA-B5901 allele was positive.The patient was diagnosed with methazolamide-induced toxic epidermal necrolysis (TEN) complicated by pneumonia,and managed with immunoglobulin (25 g/day,5 days),glucocorticoids (the largest dose equivalent to methylprednisolone 160 mg/day),fresh plasma,antibiotics,as well as other supporting and symptomatic treatments.The condition was controlled after 2 weeks,and the patient was cured and discharged from hospital after 25 days.The fact that the patient carried HLA-B5901 allele suggests that HLA-B5901 is strongly correlated with methazolamide-induced TEN or Stevens-Johnson syndrome in Chinese descendants or Han population,besides in Japanese and Korean descendants.

The objective of this study was to assess the clinical evidence for or against mood stabilizers as a treatment for Alzheimer's disease (AD). We searched 5 databases from their inception to January 2010. Five randomized clinical trials of mood stabilizers to treat human patients suffering from AD were included. These trials assessed the effectiveness of mood stabilizers as an adjunct treatment to conventional anti-dementia drugs on behavioral and psychological symptoms, especially on agitation. Methodological quality was assessed using the Jadad score. The results suggested a significant effect in favor of placebo on the Mini-Mental Status Examination [n=270, weight mean difference (WMD), -0.89; 95% confidence intervals (CIs) -1.69 to -0.09, P=0.03] and on the Neuropsychiatric Inventory total (NPI total) (n=51, WMD, 3.71; 95% CIs 0.15 to 7.26, P=0.04). There were no significant differences in change scores on total Brief Psychiatric Rating Scale (BPRS total), NPI/BPRS agitation, Cohen-Mansfield Agitation Inventory total and Physical Self Maintenance Scale between mood stabilizers and placebo. Only one of these studies was free of methodological limitations (Jadad score=5). In conclusion, based on the existing evidence, mood stabilizers are ineffective or even harmful as a treatment for AD.

Objective To evaluate the efficacy and safety of pramipexole in treating restless legs syndrome (RLS).Methods A search for randomized,double-blind,and placebo-controlled clinical trials of pramipexole in treating moderate to severe RLS using CNKI,PubMed,Embase and Cochrane Library database was carried out. A meta-analysis of included clinical trials was performed with RevMan 5.0 software.The 2 outcomes that the weighted mean difference(WMD) of change from baseline in International RLS Study Group rating scale(IRLS) score and the relative risk (RR) of response based on the Clinical Global Impression-Improvement (CGI-I) scale score were calculated for efficacy.Safety was assessed with RR of the adverse event (AE).Results A total of 5 clinical trials were included in this meta-analysis,of which 1776 patients were randomly assigned (945 on pramipexole,831 on placebo).The records of patients were pooled.Overall WMD were - 6.34 ( Z =12.76,P ＜ 0.01 ) for the change from baseline in IRLS score,and RR of response based on CGI-I were 1.65 (Z =10.39,P ＜0.01).The overall RR of pramipexole versus placebo were 1.14 ( Z =1.87,P =0.06 ) for AE.Conclusion To treat RLS,pramipexole is an effective and safe drug.

Objective To study the effect of dimethylaminoethano (DMAE) and compound amino acid injection (AA) by mesotherapy on collagen Ⅰ and collagen Ⅲ mRNA expression levels of D-galactose-induced chemical skin aging rats.Methods 80 rats were randomly divided into individual experimental group.At 18 days after D-gal induction,rats of aging treatment groups were treated with intradermal microinjection of 0.2％ DMAE+AA,0.1％ DMAE+AA,0.2％ DMAE,0.1％ DMAE,AA,and saline,respectively,once a week for 4 weeks.At 42 days after treatment,the skin wounds were harvested.HE,PCNA,hydroxyproline and collagen Ⅰ and collagen Ⅲ mRNA expression levels of every group skins were detected.Results Dermal thickness,hydroxyproline content and collagen type Ⅰ and Ⅲ mRNA expression levels of 0.1％ DMAE+ AA and 0.2 ％ DMAE+ AA groups were significantly improved (P＜0.05),but PCNA expression of sham control group was significantly higher than all of aging groups (P＞0.05).Conclusions Local co-injection of DMAE and compound AA directly into targeted tissue under mesotherapy has marked anti-aging effects on D-galactose induced skin aging model of rat by increasing the dermal thickness,collagen content and acceleration of collagen synthesis.

Objective To investigate the performance of DNA microarray in identifying 6 common Candida spp. and validating ERG11 mutations resulting in fluconazolc-resistance in Candida albicans. Methods Oligonucleotide probes were designed and synthesized targeting the species-specific sequence in the internal transcribed spacer 2 (ITS2) region of rDNA of Candida albicans, Candida tropicalis, Candida glabrata, Candida dubliniensis, Candida parapsilosis and Candida krusei, as well as 6 sequences embracing the following mutations respectively in ERG11 gene leading to fluconazole-resistance, i.c., T541C, A 1090G, C1361T, G1537A, G1547A, and T1559C, then arranged onto a chip. Twelve 50-base-pair oligonucleotides were artificially synthesized based on the above specific sequences, and utilized to hybridize with the DNA microarray. Thirty-lbur Candida strains, including 29 C. albicans, 1 Candida tropicalis, 1 Candida glabrata,1 Candida dubliniensis, 1 Candida parapsilosis and 1 Candida krusei, were detected with microarray. Genomic DNA was extracted from these tested strains and underwent multiple PCR for the amplification of ITS2 region and ERGI 1 gene. Sequencing was performed to analyze the sequence of ERG11 in 29 strains of C. albicans and the results were compared with those of DNA microarray hybridization. Results Multiple PCR successfully produced ITS2 fragment of 307-415 bp from all the 34 strains, as well as ERG11 fragment of 1712 bp from 29 C. albicans strains. DNA microarray hybridization offered the same results in species identification of the 34 strains with their given information, as well as in mutation detection of the 29 strains of C. albicans with ERG11 sequencing results. Also, the 6 synthesized oligonucleotides containing the muta- tions were identified precisely as T541C, A1090G, C1361T, G1537A, G1547A, and T1559C, and the 6 species specific oligonucleotieds were identified correctly as C. albicans, C. tropicalis, C. glabrata, C. dubliniensis, C. parapsilosis and C. krusei Both the sensitivity and the specificity of the microarray were 100%. Conclu- sion DNA microarray is a quite reliable method to identify Candida spp. and fluconazole resistance-associ- ated mutations in the ERG11 gene of C. albicans.
