Objective To compare the effects of propofol intravenous balanced anesthesia with infusion of remifentanil combined with fentanyl to simple infusion of remifentanil or fentanyl during laparoscopic cholecystectomy(LC).Methods Sixty patients scheduled for LC were randomly divided into three groups(n=20): simple remifentanil group(R),remifentanil combined with fentanyl group(RF) and simple fentanyl group(F).Mean arterial pressure(MAP),heart rate(HR) and SpO2 during the anesthesia induction phage,maintenance phage and analepsia phage,the recovery time of spontaneously breathing and consciousness from withdrawal,extubation time,pain score(verbral report score,VRS) and conscious state score(observers assessment of alertness/sedation scale,OAAS) at instant,1 h,3 h,7 h,12 h after extubation and complications of analepsia phage were recorded.Results As compared with the RF Group,the F Group and pre-induction intro-group,the R Group showed lower MAP and quicker HR when induction intubation,higher MPA and quicker HR after operation,and no obvious difference in maintenance phage was found.MAP and HR showed no obvious difference between the RF and F Group as well as within groups in induction and maintenance phage.MAP increased and HR became quicker in the RF Group when extubating and leaving operating room.All observed index at every time showed no significant differences between the R and RF Group after operation,but it prolonged significantly in the F Group.Complications of the three groups showed no statistical difference.VRS of the R Group was significantly higher than that of RF and F groups after operation(P

Objective To evaluate the protective effect of leukocyte-depleted warm blood cardioplegia on immature myocardium in infant.Methods Thirty infants with congenital heart disease whose American Society of Anesthesiologists(ASA) were Ⅱ-Ⅲ,aortic clamping time and bypass time were more than 30,40 minutes were respectively selected and divided into 2 groups:Experimental group and control group.Experimental group were perfused with leukocyte-depleted warm blood cardioplegia while control group perfused with common warm blood cardiplegia.Under monitoring the hemodynamics at surgery,the serum levels of troponin I(cTnI) and intercellular adhesion molecule-1(ICAM-1) in heparinized anticoagulant blood samples from radial artery at different time points [anesthesia induction and before extracorporeal circulation(T1),30 min after aortic clamping(T2) and aortic declamping 5 min(T3),15 min(T4)]were detected.Three pieces of cardiac muscle were taken from right atrium at different time points and the levels of myeloperoxidase(MPO) were detected.Results 1.The serum cTnI and ICAM-1 levels after aortic declamping were higher than those before operation,and the levels in experimental group were lower than those in control group(t=2.358,2.533,2.30,2.639 Pa

To observe the curative effect of treating small -incision cataract extraction by intraocular lens implantation combined with trabeculectomy for primary angle-closure glaucoma with cataract.
●METHODS: Totally 44 cases (52 eyes) of primary angle-closure glaucoma combined with cataract were selected to undergo the combined surgery, in order to observe the patients' pre - and postoperative eyesights, intraocular pressures and the postoperative complications.
●RESULTS: The postoperative eyesight was improved significantly as compared with the preoperative eyesight. The intraocular pressure was declined dramatically. The result was of statistical significance (P<0. 05). All the 52 cases' surgeries were performed by the same surgeon. The surgeries were processed smoothly, with 6 postoperative eyes of anterior chamber inflammation cell response, 3 eyes of anterior chamber fibrinoid exudate, 2 eyes of shallow anterior chamber through mydriasis and treatment with glucocorticoids and non - steroidal eyedrops before absorption, and no complications like malignant glaucoma, cyclodialysis, etc. were reported through mydriasis and pressure bandaging before recovery.
● CONCLUSlON: Treating the primary angle - closure glaucoma combined with cataract through the combined surgery has high reliability and desirable curative effect. The surgical method is simple to learn and applicable for promotion on the basic level.

OBJECTIVETo study the anti-asthmatic effect of sodium ferulate (SF) and its mechanism in guinea pig asthmatic model.

METHODSGuinea pigs were sensitized with ovalbumin as animal asthmatic model and treated with 3 different concentration of SF for 8 days. Levels of endothelin (ET) and nitric oxide (NO) in blood and lung tissue, and eosinophil (EOS) in blood and bronchoalveolar lavage fluid (BLAF) was counted at the end of trial.

RESULTSSF could significantly lower the ET content and increase the NO concentration in serum and lung tissue, reduce the number of EOS in blood and BLAF (P < 0.05, P < 0.01). Stronger effect was showed in the high dose group.

CONCLUSIONMechanism of anti-asthmatic action of SF might be to increase NO concentration, lower ET content, alleviate EOS infiltration.

Une new flavonoids named as notabilisin K (1), together with four known compounds, morusin (2), mulberrofuran A (3), neocyclomorusin (4) and mornigrol F (5) are separated from 95% ethanol extracts of the twigs of Morus notabilis. Compounds 2-5 are separated from this plant for the first time. Notabilisin I, notabilisin J exhibits certain effect against cells of HCT-116, HepG2 and A2780 with IC50 values ranging from 1.47 μmol x L(-1) to 5.46 μmol x L(-1). Morusin exhibits strong effect against five kinds of human cancer cells (BGC823, A2780, HCT-116, HepG2 and NCI-H1650) with IC50 values ranging from 0.74 μmol x L(-1) to 1.58 μmol x L(-1).
