Objective To detect the distribution of site-174G/C,site-572C/G and site-597G/A of interleukin-6 gene promoter regions in patients with endometriosis,and to analyze polymorphism of the promoter.Methods Interleukin-6 gene promoter region polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism in patients with endometriosis(n=98)and normal controls(n=99).Among the 98 patients with endometriosis,22 were defined as stageⅡ,35 as stage Ⅲ and 41 as stage Ⅳ.Comparisons between the two groups on the genotype of IL-6 gene promoter and the distributed allele frequency were done,and also among the patients of stage Ⅱ,Ⅲ and Ⅳ once significant differences were detected in genotype frequency or allele frequency in disease group and control group.Results At the site-174,the frequencies of GG,GC and CC genotypes were 100%,0% and 0%,respectively,in patients with endometriosis,while 98.99%,1.01% and 0%,respectively,in normal controls.No significant difference was found in the distribution frequency of IL-6 genotype between patients with endometriosis and normal controls.At the site-572,the frequencies of CC,CG and GG genotypes were 55.10%,42.86% and 2.04%,respectively,in patients with endometriosis,while they were 70.71 %,28.28% and 1.01%,respectively,in normal controls.A significant difference existed between the two groups.At the site-597 of IL-6 gene,no GA and AA genotypes were found in the two groups.At the site-572,the frequencies of CC,CG and GG genotypes were 59.09%,40.90% and 0%,respectively,in patients with endometriosis of stage Ⅱ,54.29%,42.86% and 2.85% in patients of stage Ⅲ,and 53.66%,43.90% and 2.44% in patients of stage Ⅳ.No significant difference was found among the three groups.Conclusion Mutations at the sites-174 and-597 of IL-6 gene promoter region were rare.Their distribution frequencies have nothing to do with morbidity of endometriosis.While at the site-572,its distribution frequency of genotype shows correlation with morbidity of endometriosis but does not show correlation with the extent of endometriosis.

Objective To investigate the changes in mechanics of respiration during perioperative period in patients undergoing orthotopic liver transplantation (OLT) without venovenous bypass. Methods Thirty patients of grade Ⅱ～Ⅲ according to the American Society of Anesthesiologists (ASA) classification, undergoing orthotopic liver transplantation without venovenous bypass, were included in this study. The respiratory parameters measured perioperatively included average airway resistance, peak inspiratory pressure, peak expiratory flow rate, dynamic compliance, work of breathing and respiratory drive. The complications of respiratory system during postoperative period were observed. Results Average airway resistance was decreased after abdominal cavity opening, decreased significantly at 5 min new hepatic phase and increased postoperatively. Peak expiratory flow rate and dynamic compliance were increased gradually after induction and increased significantly at anhepatic phase and new hepatic phase but decreased significantly on the first day postoperatively. Work of breathing was decreased after induction and decreased significantly at anhepatic phase and postoperative period. There was no significant difference in peak inspiratory pressure during operation. Compared with the values preoperation, the respiratory drive was decreased significantly during anhepatic phase and new hepatic phase. Total 35 times of postoperative respiratory complications occurred, which included pleural effusion, atelectasis, pulmonary artery hypertension, pulmonary interstitial edema and pnermonia. Conclusions There are obvious changes in respiratory mechanics during perioperative period of OLT, especially in postoperative period. Mechanical respiratory support is essential for patients until respiratory function recovers.

Objective To investigate the degradation kinetics of paeoniflorin-6-O’- benzenesulfonate ( CP-25 ) in vitro. Methods The homogenates of liver and intestine were prepared in vitro, and concentrations of CP-25 in ho-mogenates were detected by HPLC. Results CP-25 was obviously degradable in liver and intestine homogenates, and half life of degradation was decreased when levels of homogenates increased;the metabolisms of CP-25 in dif-ferent homogenates of intestine were diverse, the metabolic actions in duodenum and colon were weaker than those of jejunum and ileum. Conclusion Oral administration of CP-25 suffers first pass elimination from intestine and liver, which suggests the absorption of CP-25 could be further improved by appropriate pharmaceutical preparations.

CP-25 was slightly soluble in water and petroleum ether. The main influence factor of CP-25 stability was humidity. Conclusion The present study provides experimental basis for quality standard and formulation design of CP-25 .

To improve and optimize marine antimicrobial peptide R-1 production by a newly isolated Brevibacillus laterosporus Lh-1, Plackett-Burman (PB) design and response surface methodology (RSM) using central composite design was adopted in culture conditions. MINITAB 15.0 was used for planning the experiments, data analysis, contour diagrams and response optimizations. In this study, PB design was undertaken to evaluate the effects of the fifteen factors. By the statistical regression analysis, the significant factors affecting the novel antimicrobial peptide R-1 in submerged fermentation by Br. laterosporus Lh-1 were determined as follows: glucose, peptone and CaCl2. Then a RSM was used to optimize the above critical internal factors, and the optical concentration of the variables were deter-mined as: 15.72 g/L glucose, 6.01 g/L peptone and 3.29 g/L CaCl2. The content of R-1 was increased from 82.15 kU/mL to 116.27 kU/mL.

To further explore the result of bilingual teaching in pediatrics,we randomly chose 200 undergraduates of 4 class and released students'questionnaires about bilingual teaching with teaching content before and after class to assess students'understanding of bilingual teaching and analysed appraisal result.We found no significant difference of student score between students accepting bilingual teaching and not accepting the bilingual teaching,but there was difference for English tests and expression level.So we think that students can fully accept the bilingual teaching of pediatrics under the premise with selecting appropriate teaching methods and means.
