The study intended to evaluate the effect of high-dese atorvastafin on serum high sensitive C-reactive protein (hs-CRP) and renal function in patients with acute myocardial infarction undergoing elective pereutancous coronary intervention ( PCI ). One hundred and sixty seven patients were randomly divided into two groups: in test group (n =84) patients received oral atorvastatin 80 mg/d and in control group (n = 83) patients received atorvastatin 20 mg/d, the medication in both groups was lasted for 7 days before PCL Compared to levels at 24 h before PCI, serum hs-CRP and creatinine levels at 48 h after PCI were increased in both groups ( both P < 0. 05), and glomerular filtration rate was decreased ( P < 0. 05 ). Compared to control group, serum hs-CRP and creatinine levels 24 h before PCI and 48 h after PCI in test group were significantly lower, and glomerular filtration rate was significantly higher (P <0. 05, respectively). The incidence of contrast-induced nephropathy was lower in test group than that in control group[7% (6/84) vs.18% (15/83), P <0.05]. The results indicate that high-dose atorvastatin might be effective in protecting patients with acute myocardial infarction undergoing elective PCI from contrast-induced nephropathy via inflammatory response inhibition.

Objective To clone and identify the heat shock factors(HSFs)of Schistosoma japonicum and analyze its molec?ular structure and alternative splicing pattern. Methods The New Zealand rabbits were infected with the cercariae of Schistoso?ma japonicum and were killed and dissected 42 days post?infection,and the adult worms of S. japonicum and the livers of the rabbits were harvested. Then,the total RNA was extracted by using Trizol reagent. The Sj?hsf open reading frame(ORF)and the alternative splicing fragments were amplified by RT?PCR from the female,male and egg samples,then cloned and verified by enzyme digestion and sequencing. DNAMAN 8.0,InterPro,Mega 6 combined with the Internet databases were utilized to clarify the gene structure,functional domains,alternative splicing pattern,and the homology and phylogenetic tree of HSFs. Re?sults Sj?hsf ORF and the alternative splicing fragments were amplified from the female,male and egg samples of S. japonicum by RT?PCR. After cloning,the positive recombinant plasmids pBSjHSFf?F,pBSjHSFf?M,pBSjHSFf?E containing Sj?hsf ORF, pBSjHSFs?F,pBSjHSFs?M,pBSjHSFs?E with Sj?hsf alternative splicing fragments were identified by enzyme digestion and se?quencing. Three alternative splicing Sj?hsf isoforms were observed through sequence analysis:Sj?hsf?isoform1(2 050 bp),Sj?hsf ?isoform2(2 086 bp)and Sj?hsf?isoform3(2 111 bp);the GenBank accession numbers were KU954546,KX119143 and KX119144,respectively. All the three isoforms located in the same Contig SJC_S000780 of S. japonicum genome and all ex?pressed at female,male and egg stages,but Sj?hsf?isoform1 with a high?level expression. Sj?HSF?isoform1(671 aa)and Sj?HSF?isoform2(683 aa)had DBD(DNA binding domain),HR?A/B and HR?C domains,while Sj?HSF?isoform3(282 aa)stopped in advance without HR?C domain. Phylogenetic tree analysis of HSFs illustrated that Sj?HSFs belonged to HSF1 family,with a close phylogenetic relationship to Sm?HSFs. Conclusions There are three alternative splicing isoforms of Sj?HSF existing in the female,male and egg stages of S. japonicum,but Sj?HSF?isoform1 expresses in a high?level. This study lays the foundation for further study on molecular mechanisms of Sj?HSFs in regulating the heat shock response system.

Objective To explore the transformation of three-dimensional curve,and to observe effect of three-dimensional remodeling surgery in order to find an ideal method to achieve upper eyelid rejuvenation.Methods Retrospective analysis was conducted after surgical correction for three-dimensional reconstruction in 48 patients with upper eyelid that were female,aged 58 to 76 years;all of them had simultaneous surgery of both eyes.Using double eyelid crease incision to remove loose and redundant skin,we transplanted the herniated fat of the medial orbital septum to the deep surface of the orbicularis oculi muscle in the distinct bony structure of the extra-supraorbital margin,folded and lifted orbital septum fascia;at the same time lifted eyebrow through eyebrow incision,transplanted and filled dermis and muscle fascia flap to remodel the transverse S-shaped stereo curve of the coronal plane of the upper eyelid.Results A lot of 41 cases were followed up more than 6 months from 48 patients,except that one patient had a second surgery due to double eyelid asymmetry after one year,eyelid rejuvenation in 40 patients were improveed.Effect of 33 cases was satisfactory.Satisfaction rate was 80.49％.Less satisfaction were 6 cases,accounting for 14.63％.No satisfaction was 1 case,ac counting for 2.44 ％.Conclusions The surgery can reshape the concavity inside,the full crown outside of upper eyelid by the skin removing,fat shifting,leather fat muscle flap filling,and restore the upper eyelid to three-dimensional full round young shape.It is an ideal surgical method for eye anti-aging treatment.

OBJECTIVETo examine the expression profile and immunofluorescence localization of the major egg antigen p40 of Schistosoma japonicum (Sjp40) during granuloma formation in the liver of infected New Zealand white rabbits.

METHODSNew Zealand white rabbits were infected with S. japonicum cercariae, and the livers were harvested at 29 and 45 days post-infection (dpi). The total RNA of the liver tissues was extracted for expression profiling of Sjp40 by quantitative reverse transcription-PCR (qRT-PCR) with GAPDH of S. japonicum as the endogenous reference gene. The expression of Sjp40 in the liver were detected by Western blotting using anti-Sjp40 monoclonal antibody (mAb) 9G7 or anti-Toxoplasma gondii tSAG1 mAb Y3A8 (control) as the primary antibody. Paraffin sections of the liver were prepared for observing egg granuloma formation using HE staining and for indirect immunofluorescence assay of Sjp40 location in the trapped eggs and egg granulomas.

RESULTSThe level of Sjp40 mRNA in the eggs trapped in rabbit livers was significantly higher at 45 dpi than that at 29 dpi (P<0.05), and Western blotting confirmed the presence of Sjp40 protein in the rabbit livers at both 29 and 45 dpi. Immunofluorescence assay demonstrated localized expression of Sjp40 in the immature eggs in the rabbit liver at 29 dpi, but at 45 dpi fluorescence was detected in clusters of mature eggs containing miracidium and in the surrounding egg granulomas.

CONCLUSIONSThe transcriptional levels of Sjp40 significantly increased with the maturation of eggs trapped in the rabbit livers. Sjp40 protein spread from the eggs to the surrounding egg granuloma at 45 dpi when acute liver granulomatous lesions occur, suggesting that Sjp40 plays a key role in egg granulomas formation in the livers of infected New Zealand white rabbits.

Objective:To explore a new method for correcting the senile blepharochalasis and depression of the upper eyelid.Methods:Fourteen female patients with blepharochalasis and depression of upper eyelid were treated with subcutaneous tissue flap filling during eyebrow lifting. The under-eyebrow incision was used to remove the loose skin and lift the eyebrow, and a subcutaneous tissue flap was made to fill up the upper eyelid depression.Results:All the incisions were healed in one stage without complications such as infection and subcutaneous hematoma. 12 patients were followed up for more than 6 months. In the 3rd month after operation, 1 patient had obvious scar under the eyebrow, 1 patient had skin traction wrinkles at the eyebrow. After 6 months, the incision scar was not obvious in all patients, the appearance of eyebrow ptosis was eliminated, the upper eyelid was smooth and flat, and no absorption and further depression of the upper filler were observed; the effect was satisfactory.Conclusions:The eyebrow lifting combined with the subcutaneous tissue flap filling to correct the senile upper eyelid chalasis and depression is significantly effective with less trauma and complications, and it is worthy to be promoted.

BACKGROUNDNumerous studies have demonstrated that the peroxisome proliferator-activated receptor-γ (PPARγ) plays an important role in regulating endothelial progenitor cells (EPC) function. Telmisartan, as a partial agonist of PPARγ, may have an effect on the regulation of EPC functions. The purpose of this study was to investigate the effects of telmisartan on EPC proliferation and differentiation.

METHODSPeripheral blood derived mononuclear cells containing EPC were isolated from healthy volunteers and then cultured on fibronectin-coated dishes in the presence or absence of telmisartan. The proliferative activity of EPC was determined by colony forming units (CFU) and MTT assay. The migratory activity of EPC was assessed by transwell assay. The expression of endothelial cells (EC) markers, including vascular endothelial cadherin (VE-cadherin), von Willebrand factor (vWF) and endothelial nitric oxide synthase (eNOS), were measured by Western blotting analysis.

RESULTSMorphological analysis revealed that telmisartan significantly increased the proliferation of EPC and the number of endothelial cell colony forming units. Telmisartan could enhance the expression of the makers of mature EC, including VE-cadherin, vWF, and eNOS, which indicated telmisartan could stimulate EPC to differentiate into mature EC. Telmisartan increased the phosphorylation of Akt in EPC. The inhibition of Akt activation significantly attenuated the effect of telmisartan on EPC functions, suggesting that Akt is involved in the stimulatory effect of telmisartan on EPC differentiation.

CONCLUSIONSThe results of this study demonstrate that telmisartan promotes EPC functions via activation of Akt.
