Objective To analyze the impact of multiple factors on the incidence of pneumothorax associated with CT-guided transthoracic needle aspiration biopsy.Methods The sign of pneumothorax after 162 cases(lesion diameter from 1cm to 6cm)CT-guided transthoracic needle aspiration biopsy was observed and its relationship with multivariate factors were analyzed by multivariate logistic regression model.Results Thirty-two cases presented pneumothorax accounting for 19.8%.Single variate analysis showed that the sign of pneumothorax ralated to intercurrent COPD,distance from lesion and chest wall,needle dwelling time and lesion diameter.67 patients of intercurrent COPD with postoperative pneumothorax occurred in 22 cases (32.8%);With respect to those having lesions close to the chest wall(48 cases),and the cases with the distance between the chest wall and lesions less than 2cm(55 cases)and greater than 2cm(59 cases), the postoperative pneumothorax occurred in 0,14(25.5%),18(30.5%)cases respectively;For those patients with needle in the chest residence time of less than 10 minutes(82 cases),10—20 minutes (51 cases),more than 20 minutes(28 cases)after the occurrence of pneumothorax were 8(9.6%), 10(19.6%),14(50%)cases respectively;In contrast,those with lesion diameter less than 2 cm (65 cases),2—4cm(52 cases),more than 4cm(45 cases)were 19(29.2%),8(15.4%) and 5(11.1%)respectively.The multivariate logistic regression analysis showed that the prior three factors were risk factors of pneumothorax(OR=4.652,4.030,2.855 respectively).Conclusions To avoid the pneumothorax,caution must be taken with respect to CT-guided transthoracic needle aspiration biopsy, patients with intercurrent COPD,long distance between lesion and chest wall,and smaller lesion diameter. For operation the needle dwell time within thorax should be minimized.

Objective To evaluate the biocompatibility of vessel extracellular matrix (VECM) with bladder smooth muscle cells of rabbits,and to discuss the feasibility of vessel extracellular matrix as a matrix for urinary tract reconstruction.Methods Primary cuhured bladder smooth muscle cells (RBSMCs) iso- lated from New Zealand rabbits were implanted on VECM (1?10~6 cells/ml).The effect of VECM on meta- bolic activity,attachment,proliferation of RBSMCs were monitored in vitro by inverted light microscopy and scanning electron microscopy.The extracts of VECM and emulsion were prepared as experimental group and positive controls separately.The culture medium was used as negative control,and simple culture medium without cells was used as blank control.The cell viability was monitored by MTT method after 1-,3-,5-d see- ding.The in vivo tissue response to VECM was investigated by implanting into the subcutaneous sites of the rabbits.Results VECM exhibited nontoxic and bioactive effect on RBSMCs.RBSMCs could be attached to and proliferated on VECM and remained their morphologies.The cell proliferation rates of experimental group were 95.61%、98.34%、102.91%,respectively,after 1,3,5 d;those of negative control group were 100.00% ,respectively;and those of positive control group were 35.14%、38.95%、32.66%,respectively. There was significant difference in the rate between experimental group and positive control (P＜0.01),and no significant difference in the rate between experimental group and negative control (P＞0.05).In vivo, VECM demonstrated favorable tissue compatibility without tissue necrosis and fibrosis.Conclusions VECM exhibits nontoxic and bioactive effects on primary cultured bladder smooth muscle cells.It is a suit- able material for urinary tract reconstruction.

AIMTo study the pharmacokinetics of genistein at different doses in Beagle dogs.

METHODSSuspended in 0.5% CMC-Na solution, genistein was orally administered to Beagle dogs at doses of 2.67, 5.34 and 10.68 mg.kg(-1). At various time intervals, 1.5 mL of blood was drawn from the femoral vein of dogs in their front legs. The plasma was treated with beta-glucuronidase. The genistein in plasma was extracted twice by vortexing with 2.0 mL mixture of methyl tert-tubtyl ether and pentane (v/v = 8:2). The organic phase was removed into the tubes and then evaporated in ventilation cabinet. The residue was dissolved in 50 microL of methanol. 20 microL solution was drawn and detected by high-performance liquid chromatography. The pharmacokinetic parameters were calculated by 3P97 software.

RESULTSThe plasma drug concentration-time data were fitted to the two-compartment model. When the dose was 2.67 mg.kg(-1), the MRT and AUC of parent compound were 52.9 min and 6.7 mg.min. L(-1), respectively. When the dose rose to 5.34 mg.kg(-1), the MRT and AUC of parent compound became 224.8 min and 26.1 mg.min.L(-1), respectively. However, when the dose increased to 10.68 mg .kg(-1), the MRT and AUC of parent compound increased to 267.7 min and 33.2 mg.min L(-1), respectively. The AUC of glucuronidated genistein was 33.9, 70.1 and 140.5 mg.min.L(-1) at the dose of 2.67, 5.34 and 10.68 mg.kg(-1), respectively.

CONCLUSIONDue to significant first pass metabolism, the drug was mainly existed in the form of glucuronidated genistein in the plasma. With the increase of dose, the absorption of genistein became saturated and the half life prolonged.

Objective To compare the effects of hepatic vein occlusion with tourniquet and Satinsky clamp in reseeting liver tumor involving the second hepatic portal.Methods From Jan 2003 to Jun 2006,180 patients underwent major liver resection with the selective hepatic vascular exclusion (SHVE).According to methods of hepatic vein occlusion,they were divided into two groups:Occlusion with tourniquet(tourniquet group,n=95)and occlusion with Satinsky clamp(Satinsky clamp group,n= 85).In tourniquet group,the hepatic veins were encircled and occluded with tourniquet,and in Satinsky clamp group,the hepatic veins were not encircled and clamped directly with Satinsky clamp.Data regarding the intraoperative and postoperative courses of the patients were analyzed.Results There was no difference between the two groups regarding the operating time,ischemia time,intraoperative blood loss and postoperative complications rate.The dissecting time of hepatic veins was significantly shorter in Satinsky group(6.2?2.4 min vs 18.3?6.2 min).lu the tourniquet group,five hepatic veins(one fight hepatic vein and four common trunk of left-middle hepatic veins)could not be dissected and encircled because of the tumors involving the cava hepatic junction.Another patient's common trunk of left-middle hepatic vein was inadvertently lacerated during the dissection.Hepatic veins in these 6 patients were occluded with Satinsky clamp successfully.Conclusion Occlusion with Satinsky clamping is safer and easier procedure than tourniquets in the resection of liver tumor involving the second porta hepatis.

AIMTo study the metabolic kinetics of MN9202 in Beagle dog liver microsome.

METHODSBeagle dog liver microsomes were prepared by using ultracentrifuge method. After incubating 0.4 micromol x L(-1) MN9202 with 1 g x L(-1) microsomes for 30 min at 37 degrees C, the reaction was terminated by adding 0.5 mL alkalization. The RP-HPLC was used to determine the drug in the incubation mixture. The Michaelis-Menten parameters Km, and Vmax in Beagle dog liver microsomes were initially estimated by analyzing Lineweave-Brurk plot. Various selective CYP inhibitors were used to investigate their inhibitory effect on the metabolism of MN9202.

RESULTSThe Km, Vmax and CLint of MN9202 were (22.6 +/- 8.0) micromol x L(-1), (0.54 +/- 0.17) micromol x g(-1) x min(-1) and (0.0242 +/- 0.0009) L x g(-1) x min(-1), respectively. The metabolism of MN9202 was significantly inhibited by ketoconazole (Ket) and troleandomycin (Tro) in Beagle dog liver microsomes. Tranylcypromine (Tra) could inhibit the metabolism of drug as well. While other inhibitors showed little inhibitory effect on the metabolism of MN9202.

CONCLUSIONIt was shown that CYP3A and CYP2C19 were involved in MN9202 metabolism. The inhibitors of human CYP3A and CYP2C19 may have potential interaction with MN9202, and this can reduce the metabolism rate and increase the toxicity of MN9202.

AIMTo study the pharmacokinetics of m-nifedipine (m-Nif) in Beagle dogs.

METHODSThe Beagle dogs were divided into two groups. m-Nif was intravenously administered to the Beagle dogs in group 1 at the dose of 0. 288 mg x kg(-1), and it was orally administered to the Beagle dogs in group 2, 3 and 4 at the dose of 1.152, 3.456 and 10.370 mg x kg(-1), respectively. m-Nif in plasma was detected by reversed phase high performance liquid chromatography. The pharmacokinetic parameters were calculated by 3P97 software.

RESULTSWhen m-Nif was intravenously administered, the plasma concentration-time curve was fit to a two-compartment model and T1/2beta was 117 min. When m-Nif was orally administered, the plasma concentration-time curve was fit to a one-compartment model. T1/2 (Ke) and Cmax were 147 min and 20 microg x L(-1); at the low dose of 1.152 mg x kg(-1). T1/2 (Ke) was 122 min and Cmax was 36 microg x L(-1) at the middle dose of 3.456 mg x kg(-1). T1/2 (Ke) was 144 min and Cmax was 69 microg x L(-1) at the high dose of 10.37 mg x kg(-1), respectively.

CONCLUSIONIt was showed that the speed of elimination of m-Nif was high in Beagle dogs. The absolute bioavailability of m-Nif given orally was very low.

Administration of the immunosuppressive drug cyclosporine (CSA) after autologous peripheral blood stem cell transplantation (APBSCT) induces a systemic auto-immune syndrome resembling graft-versus-host disease (GVHD), this syndrome termed autologous GVHD has significant antitumor activity, it can reduce the incidence of tumor relapse after APBSCT. The antitumor effect of this auto-aggression syndrome can be enhanced by the administration of gamma-interferon (gamma-IFN). Five consecutive patients who received APBSCT received therapy inducing autologous GVHD. Intravenous administration of CSA [1 mg/(kg.d) for 28 days] was begin on the day of transplantation. gamma-interferon (0.025 mg/m(2) qod) was administered sub-cutaneously from days 7 throngh 28 after transplatation. Results showed that four of five occured autologous GVHD-skin demage, five in control didn't occur autologous GVHD. The relapse rate of the treated cases was 20% (1/5) versus 60% (3/5) of the control, and the median survival time of the treated cases was 20 (4 - 30) months versus 10 (2 - 20) months of the control. The data indicates that autologous GVHD results in low relapse rate of the patients rececving APBSCT.
