Objective To analysis the effect of dezocine combined anesthesia on serum levels of IL-6,MDA and SOD in patients after laparoscopic surgery for colon cancer.Methods 48 patients who were undergoing laparoscopic radical resection of colon cancer in our hospital were collected.All patients were randomly divided into experimental group and control group, 24 cases in each group, the control group was given remifentanil combined anesthesia, the experimental group received dezocine combined anesthesia, after surgery, the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α( TNF-α) , malondialdehyde ( MDA ) , superoxide dismutase ( SOD ) and incidence of adverse reactions were detected in all patients. Results After surgery, compared with control group, the serum levels of IL-6 and TNF-αwere lower in the experimental group (P<0.05);the serum level of MDA was lower, and the serum level of SOD was higher in the experimental group(P<0.05);the incidence of adverse reactions was lower in the experimental group(P<0.05).Conclusion The dezocine combined anesthesia can significantly reduce the serum levels of IL-6,TNF-αand MDA in patients after laparoscopic surgery for colon cancer,improve serum SOD level, effectively reduce inflammation and oxidative stress reaction, and have high security.

Objective To explore the application of propofol combined with small dose fentanyl in manual reduction anesthesia in orthopedics.MethodsOctober 2014 to August 2016 in Huzhou central hospital treated 120 cases of acute long bone closed fracture and ankle, shoulder dislocation and other patients, efficient analysis anesthesia, surgery time, patient recovery time, propofol is added volume and total volume, and detection 3min, 1min, 3min, 5min and waking SpO2, HR, MAP, RR values.After administration before it is administered.ResultsAnesthetic effect experimental group total efficiency is higher, the difference was statistically significant (P<0.05);after simultaneous administration of all patients 1min, 3min, 5min signs were lower than prodrug 3min signs, the difference statistically significant (P<0.05), after clear signs of its former administration 3min with no significant difference;experimental group recovery time, propofol bolus of propofol than with total control were lower, the difference was statistically significant (P<0.05);and the two groups were similar to the operation time, the difference was not statistically significant.ConclusionIn summary, propofol combined with entanyl anesthesia for patients to take the treatment of orthopedic manual reduction obviously.

The chemical structures of mequindox related metabolites in chicken plasma had been investigated using high performance liquid chromatography combined with linear ion trap quadrupole(LC-ESI/LTQ) and high performance liquid chromatography combined with ion trap-time of flight-mass spectrometry (LC-ESI/IT-TOF).Samples were separated by Hypersil BDS C_(18) and symmetry Shield columns, respectively, and 0.01% formic acid aqueous(A) and methanol(B) were used as mobile phase with gradient elution.Electros pray ionization mass spectrometric(ESI) source was used and operated in positive ion mode.When chickens were orally administered with mequindox at dosage of 20 mg/kg, blood samples were collected from the brachi al vein.Mequindox and its metabolites were extracted by the mixture of acetonitrile and acetoacetate (3:2, V/V).After solvent evaporated, the residue was dissolved in 30% methanol aqueous and the solution was detected by LC/IT-TOF MS and LC-ESI/LTQ.The molecule weight from LC-ESI/IT-TOF was analyzed by software Shimadzu's Composition and the mass chromatogram from LC-ESI/LTQ was analyzed by software Xcalibur 2.0.7.According to the molecular weight and MS~n data, referring the metabolic reaction rules, five chemical structures of mequindox related metabolites in chicken plasma were identified.Metabolites (M1-M4) were synthesized to verify the structure of metabolites.The metabolites are 3-methyl-2-(1-hydroxy) ethyl-qui-noxaline-N~1,N~4-dioxide(Ml), 3-methyl-2-(1-hydroxy) ethyl-quinoxaline-N~4-oxide(M2), 3-methyl-2-acetyl-quinoxaline-N~4-oxide, 3-methyl-2-acetyl-quinoxaline (M4), 3-hydroxymethyl-2-(1-hydroxy) ethyl-quinoxa-line-N~1,N~4-dioxide (M5).
