The nutritional status in early life have been gradually recognized that it can change the status of development and metabolism of adults.Epidemiological evidence and animal model study have found that low birth weight is the risk factors of adult metabolic syndrome and cardiovascular disease.Insulin resistance is a common pathophysiological basis.Renin-angiotensin system and insulin signaling systems interact to promote the development of insulin resistance.

10pg/ml and IL-8≥70 pg/ml as the critical value,PCT and IL-6 levels had diagnostic sensitivities of 90.6% and 75.0%,and specificities of 83.3% and 77.7%,respectively.The combination of PCT and IL-6 had a sensitivity of 81.2%,and specificity of 94.2%.The positive predictive value was of 96.2% and the negative predictive value of 73.0%.CONCLUSIONS Serum PCT appears to be a promising indicator in differentiating viral infection from bacterial gastroenteritis,but the combination of PCT and IL-6 has a more clinical value.

Objective To observe the influence of silymarin on expressions of transforming growth factor-?1(TGF-?1) and collagen type Ⅲ(Col Ⅲ) in rats with experimental tubulointerstitial fibrosis(TIF) induced by unilateral ureteral obstruction(UUO).Methods Se-venty-two Sprague-Dawley rats were randomly divided into 3 groups:sham operation group(n=24),model group(n=24) and silymarin treatment group(n=24).The rats in model group and treatment group were operated by ligation of left-ureter.The rats in sham opera-tion group operated by dissociating left-ureter were taken as controls.Rats in treatment group were fed with silymarin [30 mg/(kg?d)]24 h before operation,and rats in model group and sham operation group were treated by intragastric administration with the same volume nomal saline at the same time.Eight rats were killed at day 7,14,and 21,respectively.The score of TIF changes,histologically,was evaluated under light microscope.Expressions of TGF-?1 and Col Ⅲ in tubulointerstitial tissue in 3 groups were investigated by immunohistochemistry.Results 1.The TIF pathological index in treatment group was less than that in model group,but more than sham operation group at day 14 and 21(Pa

Background Acanthamoeba keratitis is a sort of serious infectious eye disease with high causing-blindness rate.Acanthamoeba keratitis often is misdiagnosed as fungal keratitis or viral keratitis in the early stage.Because conventional clinical diagnosis methods show a low specificity and take a long time,timely treatment often is delayed.Conventional PCR does not apply well because the lesion sample is not enough to extract DNA.However,direct PCR can amplify 18S rRNA conserved sequence of acanthamoeba keratitis without the extraction of DNA.Objective This study was to discuss the feasibility for rapid diagnosis of acanthamoeba keratitis using direct PCR to amplify the gene 18S rRNA fragment.Methods Ten acanthamoeba strains were isolated from 10 eyes with acanthamoeba keratitis in Qingdao Eye Hospital.The sensitivity of the direct PCR assay was tested using different numbers of amoebas.The specificity of the assay was tested using DNA extracted from acanthamoeba,candida albicans,pseudomonas aeruginosa,herpes simplex virus-1 (HSV-1) and normal human corneal epithelial cell.Acanthamoeba keratitis models were established using infected method in clean 6-week-old female BALB/c mice.Corneal lesion samples were obtained 1 day,3,5,7,10,15 days after modeled.The effectivity and feasibility of the direct PCR assay for rapid diagnosis of acanthamoeba keratitis were evaluated and compared with culture method,corneal smear examination and real-time PCR.Results Direct PCR primers could only amplify DNA of acanthamoeba rather than other pathogens,and 10 stains of acanthamoeba were detected at least in each sample.During the development of acanthamoeba keratitis in the mice,the diagnosis positive rate of direct PCR was 80.0%,90.0%,80.0%,70.0%,70.0% and 50.0% in 1 day,3,5,7,10,15 days after modeled with the total positive rate 73.3%,which was higher than 31.7% of culture method,56.7% of corneal smear examination and 61.7% of realtime PCR,with a significant difference between the direct PCR and culture method (P =0.005),but no significant difference was seen in the total positive rate between the direct PCR and real-time PC R (P =0.172) or corneal smear examination (P =0.056).Conclusions The direct PCR assay is a simple,rapid,highly specific and sensitive method for the rapid diagnosis of acanthamoeba keratitis,especially for the limited lesion sample.

Objective To explore the relationship between TLR3 mRNA expression on peripheral blood mononuclear cells(PBMCs)and acute rotavirus(RV)diarrhea.Methods Sixty-one children with acute RV diarrhea served as study subject,the expression of TLR3 mRNA on PBMCs was detected by real-time fluorescence quantitative RT-PCR.the concentrations of IFN-γand TNF-α in serum were measured by the method of Enzyrme-linked immunosorbent assay(EUSA).Results The expression of TLR3 on PBMCs and the serum levels of IFN-γ and TNF-α in the serious diarrhea group were 0. 820±0.051,(33.67±12.88)Pg/ml, (62.21±14.65)pg/ml,respectively,while it were 0.717±0.040,(24.01±10.06)pg/ml,(50.99± 12.18)pg/ml in the slight diarrhea group,and 0.525±0.029,(12.52±5.19)pg/ml,(28.65±7.44)pg/ml in the control group.Compared with the control group.the expression of TLR3 on PBMCs and the serum levels of IFN-γ,TNF-α in the serious and slight diarrhea group were significantly higher(P<0.01).There were significant differences between the serious and slight diarrhea group(P<0.01).There were positive relationship between the expression of TLR3 on PBMCs and tHe serum IFN-γ,TNF-α levels(r=0.431,P< 0.05,r=0.372,P<0.05).Conclusion The expression of TLR3 on PBMCs in children with acute rotavirus dialThea iS up-regulated,TLR3 and its mediated immune response are associated with the development of acute rotavirus diarrhea.

BACKGROUND:Experiments have shown that the col agen substrate has the capability of stimulating cartilage generation, but the stimulating role of different types of col agen substrates remains controversial. OBJECTIVE:To investigate the effect of type I and type II col agen on the biological characteristics of human chondrocytes cultured in vitro. METHODS:Human chondrocytes at passage were cultured onto the ordinary culture plates (ordinary plate), type I col agen-coated culture plates (type I plate), and type II col agen-coated culture plates (type II plate). cellgrowth curves were determined by MTT method after cells were cultured for 10 days. By ELISA, PCR, and 1,9-dimethyl methyleneblue technology, type I and type II col agen and glycosaminoglycan contents were quantitatively detected in cartilage cells 28 days after culture. RESULTS AND CONCLUSION:The number of cartilage cells was the highest in type II plate, which was twice of that in type I plate and five times of that in ordinary plate. Cartilage cells in type II plate secreted the least amount of type I col agen, which showed significant differences compared with the ordinary plate (P<0.01) and had no statistical y significant difference with type I plate (P>0.01). Cartilage cells in type II plate secreted the most amount of type II col agen and glycosaminoglycan, showing significant differences compared with the other two plates (P<0.01). The cartilage cells cultured in col agen plates are better than that cultured in ordinary culture plate, type II col agen culture plate is better than type I col agen culture plate in maintaining cellshape, extending the dedifferentiation pattern, and promoting celldifferentiation.
