2.Effect of Oleanic Acid on Key Enzyme Activity in Insulin-Resistant HepG2 Cell Line
Herald of Medicine 2015;(9):1139-1141
Objective To explore the effect of oleanic acid on key enzyme activity in insulin-resistant HepG2 cells. Methods The HepG2 cells were divided into normal control,model control,metformin,and oleanic acid groups.Glycogen content in insulin-resistant HepG2 cell model were detected by hepatic glycogen test kit upon treatment with oleanic acid.Activities of glucokinase ( GK) ,phosphoenolpyruvate carboxylase kinase (PEPCK),and glucose-6-phosphatase (G-6-Pase) were assayed by the glucose 6-phosphate dehydrogenase coupling colorimetric, lactate dehydrogenase coupling colorimetric and ammonium molybdate constant phosphorus methods. Results The oleanic acid enhanced glucose consumption,lowered the activity of G-6-Pase and PEPCK by 54.8% and 18.8%,respectively,and increased the activity of GK and glycogen content in also insulin-resistant HepG2 cells by 100.6% and 98.6%,respectively. Conclusion Aqueous extracts of shirako play a role in lowering PEPCK and G-6-Pase activities and inhibiting glucogenesis, resulting in the reduction of endogenous glucose in the cell. In addition,it can augment the activity of GK,accelerate the process of glucolysis,increase the glycogen content,and alleviate insulin resistance of HepG2.

Objective To investigate effects of Livin antisense oligodeoxynucleotides(ASODN) on the proliferation and apoptosis of human leukemia(HL60) cells.Methods Livin protein on HL60 cells was examined by immunohistochemistry.Specific phosphorothioate antisense oligodeoxynucleotides and missense oligodeoxynucleotides target Livin mRNA were synthesized and transfected into HL60 cells following cationic liposome.The proliferation inhibition of HL60 cells was assessed by MTT.The expression of Livin mRNA was detected by RT-PCR.Transmission electron microscope and TUNEL technology were used to detect the apoptosis and morphologic change.ResultsASODN of 600 nmol/L inhibited the HL60 cell proliferation and the expressions of Livin mRNA.The percentage of apoptosis detected by TUNEL was 38.48%?4.37%.cellar ultrastructure was markedly destroyed by Livin ASODN.A significant difference was found when compared with the control group(P
5.Pseudomonas aeruginosa Infection of Respiratory Tract in Severe Neurosurgery Patients after Tracheotomy:Clinical Analysis and Management
Chinese Journal of Nosocomiology 2009;0(17):-
OBJECTIVE To study Pseudomonas aeruginosa infection in respiratory tract of severe neurosurgery patients after tracheotomy,and discuss the prevention and management of nosocomial infection.METHODS The data of 19 severe patients admitted in neurosurgery from Dec 2005 to Oct 2007 who underwent tracheotomy were analyzed retrospectively.RESULTS Respiratory tract infection occurred in all 19 cases,the incidence rate was 100%.Eleven species and 73 strains of pathogenic bacteria were found.Thirty(41.10%)strains of P.aeruginosa were found in 12(63.16%)cases,the drug resistance rate was higher.CONCLUSIONS P.aeruginosa is the most important pathogenic bacteriaum of respiratory tract nosocomial infection in severe neurosurgery patients after tracheotomy.Strengthening the sterilization,isolation and airway management and selecting antibiotics based on drug sensitive test are the important methods to prevent and control infection.
6.Detection and Susceptibility to Antibiotics of Mycoplasma in Genitourinary Tract
Chinese Journal of Nosocomiology 2009;0(17):-
OBJECTIVE To investigate the infection status and antibiotic susceptibility of Mycoplasma in our area,so as to instruct the rational use of antibiotics.METHODS Genitourinary secretions were collected with swabs.They were cultured with the diagnostic kit of Mycoplasma(Biomerieux Company).Meanwhile the susceptibility of Mycoplasma against 9 antimicrobial agents was tested with the same kit.According to the instrnction of the kit,the results were read.The data were statistically analyzed.RESULTS A total of 382 samples were collected,and the positive rate was 44.8%.which were composed by Uu 69.6%,Mh2.9%,and Uu+Mh infection 8.8% and low titer Uu+Mh infection 18.7%.The result of drug sensitivity showed that sensitivity of Mycoplasma to pristinamycin PRI,86.5% was the highest,then was to JOS(84.8%)and CIP(26.3%).CONCLUSIONS Ureaplasma urealyticum is the major cause of infection in genitourinary system.It shows serious resistance to commonly used antibiotics.Sensitive antibiotics should be selected based on the results of bacterial culture and drug sensitivity tests so as to raise the clinical curative effects.

9.Prevention, Diagnosis and Treatment of Biliary Tract Complications after Liver Transplantation
Chinese Journal of Bases and Clinics in General Surgery 2003;0(03):-
Objective To investigate the causes of biliary tract complications after liver transplantation, and to put forward effective measures of prevention, diagnosis and treatment. Methods The literatures of recent years were reviewed and summarized. Results The causes of biliary tract complications after liver transplantation are very complex, and there are no standard preventive measures. Treatment differs according to causes. Conclusion One of the most important causes leading to biliary complications is preservative and ischemic injury. Poorly operative techniques and blood supply to biliary tract are also disastrous. Improving T tube placement can reduce the incidence of biliary complications related with T tube. To prevent biliary complications, it is crucial to completely wash the biliary tract, avoid damaging the blood supply to donor biliary tract and manage perfect biliary mucosa-to-mucosa anastomosis without tension. T tube cholangiography combined with noninvasive MRCP enables accurate depiction of the biliary tree and diagnosis of biliary complications. Doppler ultrosonography should be routinely applied postoperatively. Timely application of interventional radiological technique is a valuable nonoperative procedure for treatment of biliary complications. Meanwhile, biliary sludge or cholestasis and mixed infections of biliary tract should be handled actively and properly.
10.Polysaccharidical peptides augmented the functions of tumour infiltrating lymphocytes
Chinese Journal of Pathophysiology 1986;0(02):-
The effects of polysaccharidical peptides (PSP) on the functions of tumour infiltrating lymphocytes (TILs) in vitro was explored. The results showed that PSP, at the concentration of 37-1200?g/ml, promoted the proliferation of TILs in dose-related manner. Combination of PSP with interleukin-2 (IL-2) enhanced the cytotoxicity of TILs and reduced the dose of IL-2 used for activating TILs. The results suggested that PSP could augment the proliferation and cytotoxicity of TILs in vitro.
