BACKGROUND:Traditional treatment of tibia and fibula fractures complicated with skin soft tissue defect is mainly external fixation, wound debridement and dressing plus skin graft or skin flap transplantation after the infection is control ed and granulation grow. This method is disadvantageous due to high cost, great pain, long hospitalization stay, infection and necrosis, even the possibility of amputation.
OBJECTIVE:To explore the clinical efficacy of vacuum sealing drainage (VSD) and external fixator in the treatment of tibia and fibula open fractmes complicated with skin defects.
METHODS:A total of 38 patients with severe open fractures of tibia and fibula complicated with skin defects were selected from Benxi Central Hospital between January 2009 and September 2013. The size of skin defects was more than 5 cm2. After external fixation, the patients underwent complete debridement and dressing, fol owed by VSD treatment for 5-7 days. After granulation tissue grew and the wound became fresh, the patients received intermedite thickness skin graft. And 15 cases treated without VSD were retrospectively selected, serving as control group. The infection control rate and wound healing time in the two groups were compared.
RESULTS AND CONCLUSION:After 5-7 days of VSD treatment, VSD dressings were removed, wound infection was control ed, local wound granulation tissue was fresh. Both the wound and fractures were healed wel , no osteomyelitis or amputation occurred. Among the involved 38 patients, 23 cases were cured, 12 cases were effective, and three cases were ineffective. The total effective rate showed significant differences compared with the control group (92%vs. 53%;P<0.05). VSD can completely remove the wound secretions and necrotic tissue, improve local microcirculation, eliminate the infection, VSD plus external fixator and skin grating is a simple and effective method in treatment of tibia and fibula open fractures with soft tissue defects.

Objective We aim to investigate the association between peptidylarginine deiminase type 4 (PADl4) and colorectal cancer by genotyping threetag single nucleotide polymorphisms (tagSNP) genetic maker, to explore the role of polymorphism of PAD14 gene in development of colorectal cancer. Methods A case-control study was conducted using TaqMan-PCR methods to analyze the genotypes of three TagSNPs such as rs1886302, rs2477131 and rs1635561 for 515 patients with colorectal cancer and 549 health controls. Results There is significantly different in allelic frequencies and genotype frequencies of rs1886302 between cases and controls (P=0.039 and 0.040,respectively). The OR value of A allele and AA genotype is 0.796 and 0.731,respectively,and A allele may reduce the probability of incidence of colorectal cancer. No association Was found among SNPs of rs2477131 and rs1635561 within intronl and intron 15 in terms of coloretal cancer. Conclusion Rs1886302 on PADI4 might be a susceptible SNP to coloretal cancer.

Objective: To investigate the influence of high-fat diet on glucose metabolism and fatty acid composition of serum phospholipid in OLETF rats, a model of spontaneous type 2 diabetes mellitus. Method: Twenty male OLETF rats of 14 w age were divided into 2 groups randomly. The dietary fat in two groups contained identical percentages of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. Oral glucose tolerance test and measurement of insulin level were performed after 10 w treatment. The fatty acid composition of serum phospholipid in rats was observed as well. Results:The food intakes were comparable in 2 groups. The body weight gain in high-fat group was higher than standard group during the experiment. The result of oral glucose tolerance test and measurement of insulin level showed that the glucose metabolism in two groups had no significant difference. Only the percentage of total n-6 polyunsaturated fatty acids, 18:3(n-3) of serum phospholipid were comparable, percentages of other fatty acids were significantly different in two groups. Conclusion:With the comparable fatty acid composition, higher dietary fat lead to more body weight gain, but had no significant influence on glucose metabolism in OLETF rats. The amount of dietary fat had significant effect on fatty acids composition of serum phospholipid in OLETF rats.

Aim To establish a combined method ofβ-glucuronidase hydrolysis and LC-MS-MS analysis for the determination of scutellarein in human plasma, and investigate the pharmacokinetics of scutellarin prepara-tion in healthy male volunteers. Methods Plasma samples were prepared by enzymolysis with β-glucu-ronidase and protein precipitation with methanol. The analytes scutellarein and quercetin ( IS ) were separa-ted on an Agilent ZORBAX SB C18 column ( 2. 1 mm × 150 mm, 5 μm) with the mobile phases consisting of acetonitrile, methanol and water. Multiple reaction monitoring ( MRM) on MS was used to monitor precur-sor to produce ion transitions of m/z 285. 0→136. 8 for scutellarein and m/z 301. 1→120. 8 for IS. After method validation, this method was applied to deter-mine the plasma concentration of scutellarein in 12 male volunteers following single oral administration of 120 mg scutellarin preparation. Drug And Statistic soft-ware (1. 0) was used to process data and the pharma-cokinetic parameters were calculated. Results The assay was validated with linear range of 4 . 01-513. 38μg · L-1 for scutellarein. The intra- and inter-batch precisions ( RSD%) were within 7. 22%. The absolute recoveries were more than 84. 23%. The pharmacoki-netic parameters after a single dose were as follows:Cmax (μg · L-1 ): 159. 97 ± 58. 14; AUC(0-19) (μg · L-1·h):1151. 37 ±279. 80; AUC(0-∞)(μg·L-1· h):1194. 13 ± 264. 51; Tmax ( h):6. 33 ± 1. 67; T1/2 (h):2. 83 ± 0. 60. Conclusion The assay method is proved to be sensitive, accurate and convenient. It can be successfully applied to a pharmacokinetic study of scutellarin in healthy male volunteers.
