To compare the pharmacokinetics of syringin, eleutheroside E and isofraxidin after intravenous administration of each monomer and Ciwujia injection. Twenty-four Sprague-Dawley rats were randomly divided into four groups and intravenously administrated with syringin, eleutheroside E, isofraxidin, and Ciwujia injection, respectively. The concentrations of the three components in rat plasma were determined by LC-MS/MS. DAS 2.0 software was applied to calculate the pharmacokinetic parameters while the SPSS 17.0 software was used for statistical analysis. Significant difference (P < 0.05) was found between each monomer and the injection on the main pharmacokinetic parameters such as AUC, CL and t1,/2. Compared with the injection, the group treated with the syringin has obvious decrease in AUC, and increase in CL while the group treated with eleutheroside E has obvious increase in AUC, and decrease in CL The t1/2 of isofraxidin was prolonged in Ciwujia injection. Pharmacokinetic characters of the ingredients in the injection varied greatly from the monomer. Other constituents in the injection may have an impact on the pharmacokinetic profiles of these three components.

To establish a method for the determination of cucurbitacin in plasma samples, in order to study the in vivo pharmacokinetic characteristics of cucurbitacin in rats. Rats were intravenously injected with cucurbitacin. With diphenhydramine as the internal standard (IS), the plasma concentrations of cucurbitacin in rat plasma at different time points were determined by liquid chromatography tandem mass spectrometry (LC-MS/MS). With electrospray ionization source, the positive ion detection in the multiple reaction monitoring mode was conducted to determine the ion-pairs for target compound and IS were m/z 503.2/113.1 and m/z 256.0/167.2, respectively. Agilent ZOBAX SB-C18 column (2.1 mm x 50 mm, 1.8 microm) was adopted and eluted with methanol and 0.1% formic acid (55:45), and the flow rate was 0.2 mL x min(-1). DAS 2.0 software was applied to fit the blood concentration and calculate corresponding pharmacokinetic parameters. The rats were intravenously injected with cucurbitacin at the concentration of 3.0 mg x kg(-1). The target blood quality concentration show good linear relations within the range of 10.5-3 150 microg x L(-1) (R2 = 0.996), the lower limit of the standard curve was 10.5 microg x L(-1), and the signal to noise ratio S/N = 12. Intra- and inter-day precisions RSD was less than 6.9% and 14%, respectively; The accuracy RE ranged between 0.20% and 3.7%; The extraction recoveries ranged between 92.7% and 97.1%. Regarding the pharmacokinetic parameters of tail intravenous injection of cucurbitacin, AUC (0-t) was (811.615 +/- 111.578) microg x h x L(-1), (t1/2) was (1.285 +/- 1.390) h, CL was (3.627 +/- 0.487) L x h x kg(-1), and V(d) was (6.721 +/- 7.429) L x kg(-1). In this study, researchers established a simple, accurate, sensitive and highly specific method for determining the blood concentration of cucurbitacin, and reported the in vivo pharmacokinetic characteristics of cucurbitacin in rats for the first time.

OBJECTIVETo investigate the infection of HEV in Quzhou area of Zhejiang Province.
METHODSAll sera from blood donors in the central blood bank of Quzhou from April 2006 to April 2007 were used. Anti-HEV IgG and anti-HEV IgM were measured by EIA. RT-PCR was also performed to the samples with positive anti-HEV IgM. Genotype and sequence homology were analyzed after sequencing.
RESULTSThe positive ratio of anti-HEV IgG was 40.60%, in which the male infection ratio was higher than the female significantly (43.09% VS 36.09%; chi2=22.6; P < 0.01). The infection ratio was increased with age. The positive ratio of anti-HEV IgM was 0.43%. The positive ratio of anti-HEV IgG and the titers of antibody were higher in the inferior clinical infectors with positive anti-HEV IgM than the negative ones (P < 0.05). Two samples were positive in HEV PCR among 21 samples with positive anti-HEV IgM. The toxemia ratio was 0.4% of all the donors. And the genotype of the two samples with toxemia were both HEV-IV.
CONCLUSIONThe HEV infection was correlation with age and sex significantly and the infection occurred in the adults mainly in Quzhou area. HEV toxemia was not infrequency in the blood donors.

OBJECTIVETo sum up the clinical experience in the management of benign prostatic hyperplasia (BPH) with the prostate weighing over 80 ml by transurethral resection of the prostate (TURP) combined with 2 μm continuous-wave laser vaporesection (LVR).
METHODSWe retrospectively analyzed the clinical effects of TURP combined with 2 μm LVR in the treatment of 46 cases of BPH with the prostate volume > 80 ml.
RESULTSAll the operations were successfully accomplished. The operation time and intraoperative blood loss were (112.0 ± 20.0) min (range 86-176 min) and (77.9 ± 25.9) ml (range 50-200 ml), respectively. The catheters were withdrawn at 7 days after surgery. Transient urinary incontinence occurred in 6 cases and secondary hemorrhage was found in 2 postoperatively. Six-month follow-up revealed no urethral stricture or other complications. Compared with the baseline, the international prostate symptom score (IPSS) was significantly decreased at 6 months after operation (26.3 ± 1.8 vs 11.6 ± 1.7, P <0.05), and so were the quality of life (QOL) score (5.3 ± 0.7 vs 1.3 ± 1.1, P <0.05) and post-void residual urine (PVR) ([115.5 ± 55.6] ml vs [19.9 ± 11.6] ml, P <0.05). However, the maximum urinary flow rate (Qmax) was remarkably increased from (4.1 ± 2.6) ml/s to (16.2 ± 1.7) ml/s (P <0.05).
CONCLUSIONTURP combined with 2 μm LVR is safe and effective for the treatment of BPH with the prostate volume >80 ml.

Objective To observe the therapeutic effectiveness and safety of autologous peripheral blood stem cell transplantation (APBSCT) for poor-risk non-Hodgkin lymphoma (NHL). Methods Ten patients with poor-prognosis NHL were enrolled from October 2003 to October 2008 in our institute. Ten patients were treated by APBSCT with CY+TBI conditioning regimen (Two patients of them were treated by Double-APBSCT with MEC conditioning regimen). Results Hematopoietic reconstitution was observed in all patients.The time of neutrophil count ≥0.5×109L and platelet≥20×109/L were at day 10 (range: 7-14) and day 16 (range: 10-37), respectively. All patients achieved complete remission (CR) after transplantation. Severe toxicity and transplant related mortality were not observed. After a median follow-up of 24 (10-84) months,seven cases were in event-free survival and three cases relapsed. One of three relapsed patients died from progression of disease, the other was still alive after treatment. Conclusion APBSCT in the treatment of patients with poor-prognosis NHL is a safe, convenient and efficient treatment.
