3.Role of PPAR? in Pathogenesis of Colorectal Cancer
Chinese Journal of Bases and Clinics in General Surgery 2003;0(04):-
Objective To investigate the role of PPAR? in the pathogenesis of colorectal cancer. Methods Literatures about PPAR? and the pathogenesis of colorectal cancer were reviewed and analyzed.Results PPAR? is expressed in the nucleuses of glandular epithelia lining colon and rectum. It is normally suppressed by wild-type adenomatous polyposis coli (APC) but is up-regulated by enhanced ?-catenin/T cell factor-4 (TCF-4) binding to TCF-4-responsive elements in the PPAR promoter when an inactivating APC mutation occurs, which indicates PPAR is a potential downstream target of the APC/?-catenin/TCF-4 signaling pathway in colorectal cancer. Consistent with PPAR’s role as an APC/?-catenin/TCF-4 target, some studies reported that PPAR mRNA is frequently overexpressed in colorectal cancers of both humans and rodent animals, which indicates that PPAR is relevant to the tumorigenesis of colorectal cancer. Conclusion PPAR? is closely related with the pathogenesis of colorectal cancer.

Chinese Journal of Postgraduates of Medicine 2013;36(z1):5-7
Objective To analyze the distribution and drug resistance of Escherichia coli which separated from clinical.Methods Collecting the bacteria specimens to separating and training Escherichia coli,and then screening and monitoring drug susceptibility by The Dark Horse Microbial Analysis System,from January 2010 to July 2011.Results The Escherichia coli 486 strains which separated from clinical,the male 297 cases,female 189 cases,secretion separation 236 strains was the highest rate (48.56%),sputum 165 strains (33.95%),urine 39 strains (8.02%),and the rest of the sample 46 strains (9.47%).ESBLs 198 strains,which resistance in 19 antibiotics were higher than Escherichia coli,and it was multiple antibiotic resistance such as Aminoglycoside,Quinolone etc; Escherichia coli strains were sensitive to imipenem.Conclusion Escherichia coli which separated in surgery,respiratory tract,and urinary had a large proportion,and Resistance of Escherichia coli was serious,we should according to the Drug sensitivity of Escherichia coli,choose reasonable application of antibiotics,especially the ESBLs strains.We should strengthen the resistance testing,to provide reference for clinical rational drug use.
5.New era in autoantibodies detection: quantitation
Chinese Journal of Laboratory Medicine 2014;37(8):561-563
Autoantibodies are useful laboratory parameters for diagnosis of autoimmune diseases (AID).Methods for the detection of autoantibodies have achieved quantitative or semi-quantitative to some extent.Furthermore,with the development of detection technology,high-throughout and quantitative technology has been the trend in autoantibody measurement.Compared with qualitative results,the quantitative ones may provide more values for diagnosis,prediction,prognosis and therapeutic monitoring for AID.Therefore,although quantitative technology of autoantibodies is still faced a number of challenges,the detection for autoantibodies has come into the era of quantitation.
6.Sites of action of propofol and isoflurane on somatosensory pathway
Chinese Journal of Anesthesiology 1994;0(03):-
Objective To determine the sites of action of propofol and isoflurane on somatosensory pathway using median nerve somatosensory evoked potential(MnSSEP) .Methods Twenty-six ASA I - II patients aged 20-50 yrs were randomly divided into two groups: I propofol group( n = 13) and H isoflurane group( n = 13) .In propofol group patients received propofol infusion at a rate of 10 mg?kg-1?h-1 .Oxygen was administered via mask and respiration was assisted or controlled to maintain SpO2 at 96%-100% and PETCO2 at 35-45 mm Hg. The propofol infusion was continued until the patient failed to respond to verbal command. Six minutes later if the patient was still breathing spontaneously, the rate of propofol infusion was increased to 20-40 mg?kg-1?h-1 . In isoflurane group anesthesia was induced with propofol 2 mg ? kg-1 and intubation was facilitated by succinylcholine and anesthesia was maintained with isoflurane inhalation and intermittent iv boluses of vecuronium. The end-tidal isoflurane concentration was maintained at 0.5,1.0 and 1.5 MAC. Each concentration was maintained for 15 minutes. MAP, HR, SpO2,PCTCO2, T0(naso-pharyngeal) and BIS were continuously monitored. MnSSEP( Viking IV D type) was measured and recorded before induction of anesthesia(baseline) and in propofol group when patients became unconscious and apneic; in isoflurane group when end-tidal isoflurane reached 0.5,1.0 and 1.5 MAC.Results In group I there was no change in both latencies and amplitudes of N9 and N13'.With increasing infusion rate, propofol gradually prolonged the latencies and decreased the amplitudes of N60, P45, N35, N20 and P25 waves. In isoflurane group there was no change in the latencies and amplitudes of N9. There was no change in the latencies of N13', but the amplitudes decreased at 1.0 and 1.5 MAC. With increasing concentration, isoflurane gradually prolonged the latencies and decreased the amplitudes of P45, N60, N35, N20 and P25 waves. At 1.5 MAC the inter-peak latencies between N13'-N20 and N13'-P25 were prolonged. Conclusions The sites of action of different infusion rates of propofol and different concentrations of isoflurane are different on somatosensory pathway. The higher the doses, more widespread are the sites of action.
