Chinese Journal of Rehabilitation Theory and Practice 2009;15(4):380-381
Objective To observe the effect of intravenous small dose of ketamine combined with continuous infusion of propofol and sufentanyl in painless gastroscopy.Methods 62 patients undergoing painless gastroscopy under intravenous anesthesia were randomly divided into the control group and ketamine group with 31 cases in each group. The cases of the control group were treated with continuous infusion of propofol (target controlled infusion rate: 3.0 μg/ml) and sufentanyl (loading dose: 0.15 μg/kg, basal rate 0.15 μg/kg/h); those of the ketamine group were treated with intravenous small dose of ketamine 0.5 mg/kg combined with continuous infusion of propofol (target controlled infusion rate: 3.0 μg/ml) and sufentanyl (loading dose: 0.1 μg/kg, basal rate 0.1 μg/kg/h). The procedure of gastroscopy was started when patients were in unconsciousness and their vital signs were stable, and the infusion of medicine was stopped when the gastroscopy was finished. The systolic blood pressure (SBP) and heart rate (HR) at the time of before anesthesia, 1 minute after anesthesia, inserting the gastroscope, 10 minutes after inserting the gastroscope, and recovering from the anesthesia were recorded. The cases needing special respiratory management (SRM), displaying body movement (BM) in gastroscopy and post-operative nausea and vomiting (PONV) were recorded. The recovery time (RT) after gastroscopy was also recorded.Results No significant difference was found in SBP, HR, BM, PONV and RT between two groups ( P>0.05). Eight cases in the control group and one case in the ketamine group needed SRM before inserting the gastroscope due to transient respiratory depression ( P<0.01).Conclusion The application of intravenous small dose of ketamine combined with continuous infusion of propofol and sufentanyl in painless gastroscopy is effective and safe.
2.Leptin and chronic renal failure
Chinese Journal of Practical Internal Medicine 2001;0(02):-
Leptin,a polypeptide hormone coded by Ob-gene,has the functions of depressing appetite,reducing caloric intake and enhancing caloric consumption,etc.Leptin has a close relationship with kidney,for it is metabolized and eliminated via kidney.Meanwhile,leptin can also directly affect kidney functions,influencing the process of chronic renal failure.Furthermore,hyper-leptinemia is associated with anorexia,malnutrition and cardiovascular diseases.Different dialysis patterns may also play different roles in cleaning leptin.For example,common dialysis could not clear leptin,but other dialysis modes such as high permeability dialysis,hemodiafiltration,and mastic absorption hemoperfusion can alleviate hyper-leptinemia through cleaning leptin partly.For kidney transplantation patients,hyper-leptinemia may affect the immune balance which has been maintained for a long time.

Aim To observe the effect and primary mechanism of arctigenin ( ARG) in C6 rat glioma. At the same time, to investigate the effect of ARG com-bined with temozolomide. Methods C6 glioma rat model was established, and 90 rats were divided into six groups, which were subcutaneously administered with model, low and high ARG (0. 05 and 0. 1 mg· kg-1 , sc) , temozolomide (20 mg·kg-1 , p. o. ) , low ARG combined with temozolomide(TMZ / ARG 0. 05) and high ARG combined with temozolomide ( TMZ /ARG 0. 1 ) . The tumor specimens of brain were col-lected after tumor graft. Proliferating cell nuclear anti-gen ( PCNA ) , glial fibrillary acidic protein ( GFAP ) and CD40 in tumor specimens were determined by im-munohistochemistry. Results ① Compared with the model group, the tumor sizes of rats in the arctigenin treatment groups were decreased ( P<0. 05 ) . ②ARG
significantly decreased PCNA and CD40 expression ( P<0. 05 ) and increased GFAP expression ( P<0. 05 ) .③ Compared with model group, arctigenin combined with temozolomide decreased the tumor sizes ( P <0. 01 ) , and the tumor inhibition rate was higher than that of the arctigenin and temozolomide. At the same time, arctigenin combined with temozolomide de-creased PCNA and CD40 expression ( P <0. 01 ) and increased GFAP expression ( P <0. 05 ) , which was better than arctigenin and temozolomide. Conclusion Arctigenin inhibits rat glioma growth, and synergizes with temozolomide, which may be associated with in-hibiting PCNA and CD40 expression and strengthening GFAP expression.
