ObjectiveTo determine the allele frequency and genotypic distribution of plateletactivating factor acetylhydrolase (PAF-AH) gene polymorphism in the patients with sepsis. Methods Ala379Val,Val279Phe site genotypes were determined in patients (n=66) and healthy controls(n=68) by means of restriction fragment length polymorphism analysis of polymerase chain reaction products,DNA sequencing was used to detect the PCR product containing allele gene polymorphism.SPSS13.0 statistical software was use to analyze.Results All the samples by PCR-RFLP analysis of the PAF-AH gene in the Ala379Val site have three kinds of genotypes: in 66 cases of sepsis group there were 1 homozygous Val/Val type,19 heterozygous Val/Ala type,46 homozygous Ala/Ala type.In 68 cases of control group there were 2 Val/Val type,22 Val/Ala type,44 Ala/Ala type.The Ala379Val allele frequency and genotypic distribution in the patients with sepsis was not significantly different from those in the healthy controls.No statistically significant difference was observed between the survival group and the death group ( P＞0.05 ).PAFAH gene of Va1279Phe polymorphism could have three kinds of genotypes.All 66 patients in the sepsis group were the homozygous Val/Val type.Control group 68 cases,only one case was homozygous Phe/Phe type,and the others were homozygous Val/Val type,not found heterozygous Val/Phe type.The Val279Phe genotypic distribution and allele gene frequency in the patients with sepsis was not significantly different from those in the healthy controls; no statistically significant difference was observed no statistically significant difference was observed between the survival group and the death group ( P＞0.05 ).ConclusionNo associations were found between PAF-AH gene Ala379Val and Val279Phe polymorphisms and sepsis susceptibility,prognosis and severity.

OBJECTIVE To investigate the repressor SmeT and other sequences of efflux pump SmeDEF in the clinic isolates of Stenotrophomonas maltophilia to involve in antibiotic resistance. METHODS The mRNA level of smeD examined the resistance profile of the clinical strains to antimicrobials was by agar dilution and their reaction to pump inhibitor was investigated by RT-PCR,and the smeD-smeT fragment was amplified by PCR,and then sequenced.Adding poly(A) to 3′ end of RNA,applying 3′RACE,nested PCR,then sequence-analysis. RESULTS The amino acid sequences of the forepart of SmeT were conservative in all the 7 strains.In antibiotic-resistant strains with positive reaction to pump inhibitor,the intergenic sequences of smeD-smeT were different from those in sensitive ones.The variations in(-165 to-82)nt of smeT and several nucleic acids before the start codon of smeT,possibly involved in antimicrobial resistance.All isolates didn′t have Leu166Gln mutation within the SmeT protein of D457R,which was reported possibly associated with antibiotic resistance.The resistant strains with efflux positively inhibited had Asp218Glu substitution,different from the negatively-inhibited ones. CONCLUSIONS The expression level of SmeDEF is related with the antibiotic resistance of S.maltophilia.The possible resistance mechanism includes the variations in the intergenic smeD-smeT and/or smeT codon sequence.

Objective To study the expression of active efflux pump AdeABC in clinical Acineto-bacter baumannii islates and whether this efflux pump confers resistance to antibiotics. Methods The anti-biotic susceptibility and the function of efflux pump inhibitor were tested by micro-dilution broth method. The expression of adeB was examined by RT-PCR. The controlling gene adeRS was amplified by PCR and se-quenced. Results Thirty multidrug resistance Acinetobacter baumannii isolates and 5 sensitive isolates for PCR were both abtained the expected products of adeB and adeRS. The mRNA expression of adeB in 15 multidrug resistance(MDR) isolates were positive, but there was no expression of adeB in 5 sensitive iso-lates. The mutations of adeRS existed in 2 MDR isolates. Conclusion The expression of AdeABC may in-volved in the resistant mechanisms of the clinical MDR Acinetobacter baumannii isolates.

Objective:To explore the effect of sarpogrelate on platelet function in patients at the bridging stage before coronary artery bypass grafting (CABG).
Methods: A total of 40 consecutive patients with peripheral artery stent and scheduled for CABG in our hospital from 2011-05 to 2013-04 were enrolled in this study. The patients were randomly divided into 2 groups, Low molecular weight heparin (LMWH) alone group, n=19 and Sarpogrelate+LMWH group, n=21. The medications started at 5-7 days before CABG and stopped at 24 h before CABG. The platelet inhibition rates (platelet aggregation induced by collagen+ serotonin) were examined and compared between 2 groups at the baseline (before randomization), 24h and 1h before CABG respectively.
Results: The platelet inhibition rates were similar between 2 groups at the baseline (87.33 ± 6.82) % vs (86.11 ± 6.87) %, P=0.577 and 1h before CABG (62.60 ± 12.39) % vs (56.19 ± 14.99) %, P=0.148. At 24h before CABG, the platelet inhibition rate in Sarpogrelate+LMWH group was higher than that in LMWH alone group (83.87 ± 8.99)%vs (63.13 ± 10.88)%, P<0.001. Compared with the baseline, the falling range of platelet inhibition was lower in Sarpogrelate+ LMWH group at 24h before CABG, (3.46 ± 6.18) % vs (22.98 ± 9.43) %, P<0.001 and the falling range was similar between 2 groups at 1h before CABG (24.73 ± 14.19)%vs (29.92 ± 14.28)%, P=0.257.
Conclusion: Sarpogrelate + LMWH may result better platelet inhibition rate with quicker recovery of platelet function upon the medication stopping, which might be a feasible management in patients at the bridging stage before CABG.

Objective: To explore the effect of the aortic arch type on technical indicators in patients with carotid artery stent implantation.
Methods: We retrospectively analyzed 224 consecutive patients treated in Fu Wai hospital for unilateral carotid artery stent implantation from 2011-01 to 2012-12. We summarized the catheter category, type and the operating techniques including ① retracement, turn and insertion of the catheter, ② retracement, turn of catheter+the guidance of guide wire,③ retracement, turn of catheter+the guidance of guide wire+the supporting of another catheter, ④ using special graphic catheter+the guidance of guide wire+the supporting of another catheter. The procedural X-ray exposure time, dosage of contrast agent and operation related complications were recorded. According to Myla classiifcation, the aortic arches were divided into Myla I, Myla II and Myla III types.
Results: There were 7/224 (3.1%) patients with Myla I aortic arch, 113 (50.4%) with Myla II aortic arch and 104 (46.4%) with Myla III aortic arch. A total of 48/104 (46.2%) Myla III patients used special techniques (tech③, tech④), it was more than the patients with Myla I, (1/7,14.3%) and Myla II (17/113, 15.0%), P<0.01. The patients with Myla III aortic arch had the longer X-ray exposure time and used the higher dose of contrast agent, all P<0.01. The procedural success rate in patients with
Myla III was 96.2%, it was lower than those with Myla I (100%) and Myla II (100%), P=0.045. The procedural complication rate in patients with Myla III was 22.1%, it was higher than those with Myla I (0%) and Myla II (8.9%), P=0.007.
Conclusion: The aortic arch type is the important inlfuential factor for the techniques used in carotid stent implantation. There were more dififculties and complications for stent implantation in patients with Myla III aortic arch.

Objective: To compare the clinical value of total gastrectomy and proximal gastrectomy in the treatment of gastric fundus carcinoma. Methods: 80 patients with gastric fundus cancer were divided into observation group and control group according to the random number method.The observation group was treated with total gastrectomy, and the control group was treated by proximal gastrectomy.The operation-related conditions, such as operation time, intraoperative bleeding and postoperative anal exhaust time of the two groups were compared.After surgery R0 resection rate and 2-year survival rate were analyzed. Results: The operative time in the observation group was (86.3±1.9)min, which was shorter than (102.3±2.6)min in the control group (t=31.424, P<0.05). The intraoperative blood loss of the observation group was (180.5±15.0)mL, which was less than (230.0±25.0)mL of the control group (t=10.738, P<0.05). The anal exhaust time of the observation group was (41.5±2.1)h, which was shorter than (56.9±3.3)h of the control group (t=24.900, P<0.05). The percentage of pathologic R0 resection of the observation group was 32.5%(13/40), which was higher than 5.0%(2/40) of the control group (χ²=8.205, P<0.05). The 1-year survival rate and 2-year survival rate in the observation group were 92.5%, 67.5%, respectively, which were significantly higher than those in the control group(60.0%, 42.5%, χ²=4.943, 5.051, all P<0.05). Conclusion Compared with the proximal gastrectomy, the total gastrectomy in the treatment of gastric fundus carcinoma has shorter operation time, less intraoperative blood loss, quicker postoperative recovery, higher pathologic resection rate and survival rate.
