Objective To investigate the association of eIF4E and MMP-9 gene polymorphisms with psoriasis vulgaris in Han population of Shandong province.Methods A population based case-control association study was carried out in 188 patients with psoriasis vulgaris and 280 healthy human controls of Han nationality from Shandong province.Taqman SNP genotyping assay was performed to assess three SNPs,including rs4810482 and rs3918254 in MMP-9 gene and rs11723037 in eIF4E gene.Pairwise linkage disequilibrium was evaluated by using Haploview 4.2 software,and the frequencies of alleles and genotypes were analyzed by using Plink 1.07 software.Results The frequency of rs4810482 T allele was significantly lower in patients with psoriasis vulgaris than in the normal human controls(OR =1.49,95％ CI:1.12-1.99,P ＜ 0.01),and the significant difference still remained under recessive and dominant model.Bioinformatic analysis revealed that the rs4810482 altered the binding site of transcription factor,while no association was observed between psoriasis and either of the other two SNPs.Conclusions The SNP rs4810482 located at the upstream regulatory region of MMP-9 gene is significantly associated with psoriasis,hence,MMP-9 gene may be a susceptibility gene for psoriasis in Han population of Shandong province.

Objective To screen for differentially expressed proteins in sera from patients with common types of psoriasis,and to identify plasma protein markers for psoriasis.Methods Serum samples were collected from 6 patients with progressive psoriasis vulgaris,5 patients with erythroderma psoriaticum,and 6 healthy human controls,and then pooled into 3 pools:psoriasis vulgaris pool,erythroderma psoriaticum pool and control pool.After removal of high-abundance albumin and IgG,the pooled samples were analyzed by two-dimensional electrophoresis (2-DE).An electrophoretic gel image analysis software was used to locate differentially expressed protein spots followed by peptide mass fingerprinting with matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS).The National Center for Biotechnology Information (NCBI) protein databases were then searched for the identification of differentially expressed proteins.Results All the three pooled serum samples were well seperated by 2-DE.As the gel image analysis software showed,there were 33 protein spots differentially expressed between the patients with psoriasis vulgaris and the healthy controls,17 between the patients with erythroderma psoriaticum and the healthy controls,and 26 between the patients with psoriasis vulgaris and those with erythroderma psoriaticum.Finally,14 proteins were identified as differentially expressed proteins.The patients with psoriasis vulgaris showed higher expression of complement component 3,interleukin-16,vitamin D-binding protein and α1-antitrypsin compared with the healthy controls; the patients with erythroderma psoriaticum showed increased expression of complement component 3,complement component H,α1-antitrypsin,hemopexin and haptoglobin,but decreased expression of serum amyloid protein compared with the healthy controls,as well as enhanced expression of α1-antitrypsin,complement component H,complement component 4 and haptoglobin compared with those with psoriasis vulgaris.Conclusion Differences exist in serum protein profiles between patients with psoriasis vulgaris and erythroderma psoriaticum,and healthy human controls.

AIM: To evaluate the effects of total flavonoid of chrysanthemum on the expressions of Fas and FasL in male rabbits with dry eye, and to investigate the therapeutic effects of the total flavonoid of chrysanthemum on dry eye.
METHODS: Totally 150 male Japanses white rabbits were divided into blank group ( group A ) , sham -operated group ( group B ) , model group ( group C ) , androgen control treatment group (group D), and total flavonoid of chrysanthemum treatment group ( group E ) . The dry eye model was established with orchiectomy on group C, D and E. Rabbits in group E were treated with total flavonoid of chrysanthemum. Rabbits in group D were treated with androgen intramuscular injection. Rabbits in the group A, group B, group C was treated with normal saline. All rabbits were detected with Schirmer's Ⅰ test and tear break-up time (BUT). Fas, FasL were checked on immunohistochemistry.
RESULTS:The Schirmer's I test values of group E was significantly higher than that of group C ( P<0. 01 ) and the BUT value of group E was significantly longer than that of group C ( P<0. 01 ). The quantity of positive expression of Fas in glandular tube cell and acinar epithelial celland apoptosis cells of group E after treatment at 1, 3, 5mo were significantly lower than that of group C, cell population of the positive expression of FasL was obviously higher than that of group C (P<0. 01).
CONCLUSION:The main component of chrysanthemum is flavonoid, which could significantly inhibit happening of dry eye in rabbit after androgen level lowered and lacrimal gland apoptosis and keep basic tears secretory volume and tear film stability.

Objective To explore effect of physic temperature dropping by ice blanket on incidence of pressure ulcer of stroke patients in ICU, and normalize the basic nursing procedure during temperature reduc-tion.Methods 230 fever patients were randomly divided into the group A(control temperature with ice blan-ket,108 cases)and the group B (control temperature with routine measure,122 cases).Thc incidence of pressure ulcer and surface temperature of pressed position in the two groups were compared.Results The incidence of pressure ulcer and surface temperature of pressed position in group A was lower than those of group B.Conclusions The incidence of pressure ulcer can be reduced by using ice blanket for physic temperature dropping.The pressure of pressed position were descended by alternative prostration and lateral position.

Objective To construct an expression plasmid carrying the specific siRNA of survivin gene,and to evaluate its silencing effect on the expression of survivin gene and its inhibition effect on the growth of gastric cancer cells.Methods The specific siRNA of survivin gene was designed and synthesized,and an expression plasmid pAdGFP-siRNA was constructed.Gastric cancer cell line SGC-7901 was cuhured and transferred with pAdGFP-siRNA,then the silencing of survivin gene expression and the growth inhibition of cancer cell mediated by pAdGFP-siRNA were identified.Results The growth of gastric cancer cells was inhibited after transferring the pAdGFP-siRNA,with the inhibition rate of 68.2% compared to the control group.Immunohistochemistry showed that the specific siRNA markedly silenced the expression of survivin gene in cancer cells.Conclusions The overexpression of survivin gene in gastric cancer cells results in the high proliferation and the resistance to the chemo- and radio-therapy of the cancer cells.The specific siRNA can markedly silence the expression of survivin gene and inhibit the growth of cancer cells.

Objective To evaluate the value of proton magnetic resonance spectrum (1H-MRS) in the differential diagnosis of Alzheimer's disease (AD) and vascular dementia (VD) patients with white matter lesions (WMLs).Methods Multi voxel 1H-MRS were performed to 30 patients with AD,30 patients with VD,and 30 normal control volunteers.The levels of the N-acetylaspartate (NAA),myo-inositol (mI),glutamate (Glu),and creatine (Cr) were measured in the white matter adjacent to the lateral ventricles.The ratios of NAA/Cr,mI/Cr and Glu/Cr were calculated and compared among the group.Comparisons of the 1H-MRS indexes among AD,VD and NC group were conducted by one-way ANOVA.Results NAA/Cr ratios of the region of interesting in AD (1.59±0.15)and VD(1.53±0.12) group were significantly decreased compared with NC (1.79±0.22)group (P＜0.05),and Glu/Cr ratios of the region of interesting in AD(0.41±0.03) and VD(0.49±0.04) group were significantly decreased compared with NC(0.57±0.05) group (P＜0.05).However,there were not significant differences for NAA/Cr ratios of the paraventricular white matter region between AD and VD group (P＞0.05),and Glu/Cr ratios in AD and VD groups were significantly different (P＜0.05).A significantly increased mI/Cr was found in AD (0.68±0.05) group than in VD(0.57±0.04) and NC(0.55±0.03) groups (P＜0.05),and there were no significant changes in mI/Cr ratios between VD and NC groups (P＞0.05).Conciusion Multi-voxel 1H-MRS is an effective method in the differential diagnosis of dementia,and changes of the mI/Cr and Glu/Cr ratios of the white matter adjacent to the lateral ventricles may help to identify the AD and VD patients.

Objective To observe and compare the association of serum levels of of complement component 3(C3)and high-sensitive C-reactive protein(hs-CRP)with insulin resistance in non-diabetic subjects. Methods 587non-diabetic Chinese were recruited. Weight, height, blood pressure, waist circumference, fasting plasma glucose,fasting serum insulin, blood lipids, C3 and hs-CRP were measured. HOMA index(HOMA2-IR)was calculated.Insulin resistance was defined as the upper quartile of HOMA2-IR. Results C3 and hs-CRP were significantly higher in subjects with insulin resistance compared with subjects without insulin resistance. After controlling for age, gender,body mass index, and waist circumference, C3 was positively and significantly correlated with HOMA2-IR(r = 0.19,P＜0.01). As C3 increased, subjects were 3.78(OR= 3.78, P＜0.05)times more likely to suffer from insulin resistance, after adjustment for age, gender, systolic blood pressure, diastolic blood pressure, total cholesterol,triglycerides,high-density lipoprotein cholesterol, and waist circumference. However, hs-CRP was not significantly correlated with insulin resistance. Conclusions Serum complement component 3 has a more marked association with insulin resistance than hs-CRP in non-diabetic Chinese.

The expressions of StAR (steroidogenic acute regulatory protein) mRNA in testes from 7,14,23 and 37 day-old piglets were studied by tissue in situ hybridization. The results indicated that in the testes of piglets, StARmRNA was expressed in Leydig cells of pig testes. The expression level of StARmRNA was lower in 7 days piglets but higher in 14,23,37 days. The results indicated that StAR gene played an important role in steroid biosynthesis.
