RESULTSGood results were achieved in all the patients with primary healing. No flap necrosis happened. The result was satisfactory.

CONCLUSIONSWith bilateral subdermal soft tissue "C" flaps and " lambda" flap, nasal base depression deformities and lip whistle deformities can be corrected. It is an ideal method for correction of deformities after BCCL repair.

To prepare ginseng saponin Compound K with ultrasound-assisted total zymolytic ginseng saponins. The conversion rate was taken as the index to detect the pre-treatment factors such as ultrasonic power and ultrasonic time, as well as the impact of enzymatic factors, such as pH value, temperature, concentration of substrate, dosage of enzyme and reaction time, on the conversion rate. The response surface method was used to optimize the preparation conditions. The enzymolytic products were identified with MS, 1H-NMR and 13C-NMR. The results showed that the optimum conditions of the ultrasound-assisted enzymolysis were 250 W for ultrasonic power, 15 min for ultrasonic time, 5.5 for enzymolytic pH, 50 degrees C for enzymolytic temperature, 36 h for enzymolytic time, 4:5 for enzymolytic dosage: substrate and 1.0 g x L(-1) for concentration of substrate. The relative molecular mass of reaction products was 622.4. Therefore, the nuclear magnetic map verified that the reaction product was rare ginseng saponin Compound K. Under the above conditions, based on the total zymolytic ginseng saponins, the conversion rate of rare ginseng saponin Compound K was 6.91% in proportion to the total of ginsenosides. The process features gentle reaction conditions, high conversion rate and simple and reliable process, which is suitable for industrial production.

Objective To explore the changes of renin-angiotensin-aldosterone system in pediatric severe sepsis treated with continuous blood purification(CBP).Methods Prospective study,35 cases of critically ill children diagnosed with severe sepsis and admitted to PICU of Shanghai Children's Hospital of Shanghai Jiaotong University from June 2012 to May 2014 served as reseach objective.Based on the monitoring of vital signs,including central venous pressure,arterial blood pressure,mean arterial pressure,patients were treated with conventional therapy,as antibiotics,fluid therapy,and CBP by mode of continuous veno-venous hemodiafiltration or high volume hemofiltration.Plasma levels of rennin activity,angiontensin Ⅱ and aldosterone were measured by radioimmunoassay before and 24 h after CBP.Twenty-five cases of blood samples taken from the children collected from health care for liver function examination were matched as control group.Results Plasmalevelsofrenninactivitywere(2.11 ±1.93) pg/(L·h),(1.27±1.56) μg/(L·h),(0.37 ± 0.22) μg/(L· h) before and 24 h after CBP and control group,respectively.The levels of angiontensin Ⅱ were (426.78 ±332.37) ng/L,(364.40 ± 325.51) ng/L,(41.70 ± 10.81) ng/L,respectively.And the levels of aldosterone were (255.12 ± 218.18) ng/L,(134.92 ± 104.13) ng/L,(106.88 ±43.18) ng/L,respectively.The plasma levels of rennin activity,angiontensin Ⅱ,and aldosterone were higher in sepsis cases than in control group,while decreased obviously after CBP treatment(P ＜0.01,P ＜0.05).Eleven cases died and mortality was 31.4％ (11/35).After 24 h of CBP,the mean arterial pressure improved in 26 cases with septic shock and dopamine dose reduced(P ＜ 0.01).Conclusion The reaction of renin-angiotensin-aldosterone system is increased significantly in pediatric severe sepsis.CBP can down-regulate the levels of rennin activity,angiotensin Ⅱand aldosterone,but not worsen the circulation function.

The coding sequence for the mature peptide of porcine lactoferrin (Plf) was synthesized according to the codon usage of lactobacillus, to establish optimized porcine lactoferrin Lactobacillus expression system. The gene was ligated into the Xho I/BamH I site of Lactobacillus expression vector pPG612.1 and the recombinant plasmid pPG612.1-plf was transformed individually into Lactobacillus casei ATCC393, Lactobacillus pentosus KLDS1.0413, Lactobacillus plantarum KLDS1.0344 or Lactobacillus paracasei KLDS1.0652 by electroporation. After induction with xylose, expression of the recombinant proteins was detected by Western blotting and confocal laser scanning microscopy. Secretion of recombinant Plf proteins from four recombinant species was determined quantitatively by ELISA. The antibacterial activities of recombinant proteins were measured by agar diffusion method. The result shows that Plf was correctly expressed in four species of recombinant lactobacillus, with molecular weight of about 73 kDa. The expression levels in recombinant Lactobacillus casei, Lactobacillus pentosus, Lactobacillus plantarum, Lactobacillus paracasei were 9.6 μg/mL, 10.8 μg/mL, 12.5 μg/mL and 9.9 μg/mL, respectively. Antimicrobial activity experiment shows that the recombinant proteins were active against E. coli, Staphylococcus aureus, Salmonella typhimurium, Listeria, Pasteurella. The recombinant Plf expressed by recombinant Lactobacillus plantarum showed the best antibacterial activity among all recombinant lactobacillus species. These data represent a basis for the development and application of porcine lactoferrin from recombinant lactobacillus.

Objective To compare the perioperative outcomes of laparoscopic liver resection (LLR) versus open liver resection (OLR) for hepatocellular carcinoma (HCC).Methods A total of 89 HCC patients undergoing liver resection between January 2012 and November 2016 were enrolled.Nonparametric tests were employed to compare the clinicalpathological characters and preoperative outcomes.Results No significant difference was observed in clinicalpathological features and postoperative morbidity.LLR group had shorter hospital stay (Z =4.642,P ＜0.01),lower serum ALT level in 1st,3rd and 5 day (Z =2.157,3.089,2.384,all P ＜0.05) and AST level in 1st-and 3rd-day postoperatively (Z =2.688,2.566,all P ＜0.05).The growth rate in serum total protein (TP) and albumin (ALB) postoperatively is higher for LLR group (y =2.348 4x + 51.696 vs.y =0.902 9 + 35.532),(y =1.539 9x + 29.68 vs.y =0.732 9x + 30.406).Conclusion LLR allows quicker liver function recovery and shortens patients' postoperative hospital stay.

OBJECTIVE: To study the relationship between the radiotherapy resistance and autophagy. To provide a theoretiacal basis for drugs that regulate autophagy to improve radiotherapy sensitivity. METHOD: Flow cytometry (FCM) was performed to analyze the distribution of the cell cycle of CNE2 and CNE2/DDP cells under the action of X radiation. The expression of autopagy-specific gene Beclin1 and microtubule-associated protein light chain 3β (MAPLC3β) in CNE2 and CNE2/DDP cells was determined by real time PCR and Immumofluorescence staining. RESULT: CNE2/DDP and their parental CNE2 cells produced the G2-M phase arrest under the action of X radiation. With the radiation dose increasing,The cells which in the G2-M phase were more and more (P<0. 05). The G2-M phase arrest in CNE2/DDP cells was more obvious than in CNE2 cells (P<0. 05). The expression of Beclin1 and MAPLC3β in CNE2 and CNE2/DDP cells increased under the action of X radiation. What's more, the raise was more and more obvious with the increase of the irradiation dose(P<0. 05). The expression levels of Beclin1 and MAPLC3β in CNE2/DDP was lower than that in CNE2 cells (P<0. 05). CONCLUSION Autophagic cell death may be the one manner of death in nasopharyngeal carcinoma CNE2 and CNE2/DDP cells under the action of X radiation. The radiation resistance of CNE2/DDP cells may be related to the low expression of autophagy-related genes.
