Objective To discuss the liver function recovery affected by the portal vein flow in patients who underwent adult-to-adult living donor liver transplantation using the right lobe. Methods Seventy-four donors and recipients were included in this study. Intraoperative Doppler ultrasound (IOUS)were performed before splitting the donor liver and 1 hour after the graft reperfusion. The diameter and velocity of portal vein were measured and recorded for calculation of portal vein flow(PVF). Liver function tests were undertaken at the day 2nd,7th, 15th and 30th postoperative,respectively. Results One hour after reperfusion of 74 grafts,the PVF were significantly increased (2. 84 ± 0. 93) fold. Seventy-four grafts were divided into 4 groups according to the different degrees of the increase of PVF. The levels of blood bilirubin total(TBIL) among 4 groups were differently at the day 2nd,7th, 15th and 30th postoperative. High PVF contributed to recipient's prolonged hyperbilirubinemia ( P ＜0. 001 ). The levels of ALT, AST among 4 groups were differently at the day 7th, 15th and 30th postoperative( P ＜0. 001). Conclusions Detection of portal vein hemodynamics in living donor liver transplantation by IOUS may assist surgeon to anticipate the graft's function and take surgical therapies to secure the graft and the recipient.

Objective To evaluate the clinical efficacy and safety between Alprostadil regular therapy in the patients with ischemic stroke. Methods We searched the electronic databases (WANFANG DATA,CNKI,and OVID) in order to obtain the randomized controlled trial (RCT)with interventions of lipo-prostaglandin E1 from January 1,2003 to March 1,2011. The methodological quality of the trials was assessed using four standards:random allocation program,allocation concealment,blind and quit.A meta-analysis of included clinical trials was performed with Revman 5.0 software. Results 13 trials were included and the data were divided into 3 groups by different outcomes,the effective rate(12 trials),the neurological deficit score(CCS,6 trials) and the daily life score (4 trials). Meta-analysis showed that after treatment,there were differences in neurological deficit (OR:-4.76,95％ CI:8.46,-1.06)and daily life(OR:0.95,95％ CI:-1.52,-0.38) between lipo-PGE1 treatment group and regular treatment group.The effective rate were higher in lipo-PGE1 treatment group than in regular treatment group (OR:3.75,95％ CI:2.45,5.75).The improvement in the overall symptoms of ischemic stroke after lipo-PGE1 therapy was better than regular treatment.In the occurrence of adverse reactions,18 cases appeared in lipo-PGEl treatment group(among which 11 cases were vascular stimulating reactions after injection),1 case in regular treatment group. Conclusions Lipo-prostaglandin E1 is an effective drug for ischemic stroke in view of its improvements in cure rate,neurological deficit and activities of daily life.

Objective To assess the therapeutic effect of combination chemotherapy of gemcitabine and cisplatin by double way plus implantation of radioactive seed 125I implantation in treating stage Ⅲ non-small cell lung cancer. Methods Sixty cases with stage Ⅲ non-small cell lung cancer were randomly divided into two groups with random number table. In group A (in interventional treatment group, n = 30),the gemcitabine 1000 mg/m2 and one third of the cisplatin 100 mg/m2 was given using seldinger technique for transcatheter bronchial arterial infusion chemotherapy on day 1. Two-thirds of the cisplatin 100 mg/m2 was infused in veins on day 2 and 3. The gemcitabine 1000 mg/m2 was infused in veins on day 8, 21 days for a period. In group B (interventional - 125I groups), the method of combination chemotherapy of gemcitabine and cisplatin was the same as in Group A. After ten days of arterial perfusion, 125I seeds were implantated, 21 days for a period. All patients received at least 2 cycles. The imaging evaluation of patients after treatment standards included complete remission (CR), partial remission (PR), stable (SD),progressive disease (PD), effective rate (CR + PR)/30 and clinical benefit rate (CR + PR + SD)/30.Non-parametric rank sum test was used to compare short-term effect of the two groups treatment of two cycles.x2 test was used to compare year survival, Kaplan-Meier method was used to calculate median survival,log-rank test method was used to difference between the groups. Results In group A, there were 17 PR,9SD and 4 PD. The overall response rate was 56. 7% (17/30) and clinical beneficial rate was 86. 7% (26/30). In Group B, there were 2 CR, 21 PR, 7 SD. The overall response rate was 76.7% (23/30) and clinical beneficial rate was 100% (30/30). There was significant difference between the two groups (P =0. 036). In group A, the 1 year survival rate was 46. 7% (14/30) and the 2 year survival rate was 36. 7%(11/30), median survival time (MST) was 10 months . In group B, the 1 year survival rate was 76. 7%(23/30) and the 2 year survival rate was 63. 3% (19/30) , median survival time (MST) was 27 months.There was a significant difference between two group in 1 year survival rate (P = 0. 017), 2 year survival rate (P = 0. 039) and median survival time (P = 0. 006). Conclusion The treatment effects of Ⅲ stage non-small cell lung cancer by gemcitabine and cisplatin combination chemotherapy with double way plus radioactive seed 125I implantation was better than gemcitabine and cisplatin combination chemotherapy with double way.

Objective To observe the therapeutic effects of arsenic trioxide combined with transcatheter arterial chemoembolization on treatment of primary liver cancer with pulmonary metastases.Methods Sixty patients were randomly divided into two groups:group A (treatment group,n =30) and group B (control group,n =30).Group A was received periodic transcatheter arterial chemoembolization (TACE) and 10 mg arsenic trioxide by intravenous infusion for 5 hours per day,3 days after TACE.Each cycle consisted of 14 days' administration,and repeated after 2 weeks.Each patient was received 3-4 successive cycles.Group B was received periodic TACE alone.Objective efficiency,benefit rate,quality of life and the correlates with metastatic tumor size and number in the both groups were recorded.Results The objective efficiency was 26.7％ (8/30),and the benefit rate was 60.0％ (18/30) in group A,while they were 0 and 16.7％ (5/30) in group B with significant statistics differences (x2 =7.067,P =0.008;x2 =11.915,P =0.001).The quality of life was improved in 4 patients and stable in 18 of group A,while no patient was improved and 13 were stable in group B (x2 =9.669,P =0.008).There was a significantly positive correlation between the tumor burden and therapeutic effect (Kendall r =-0.765,P ＜ 0.001 ;Spearman r =-0.821,P ＜ 0.001).Conclusion Arsenic trioxide combined TACE is an effective treatment method in treating primary liver cancer with pulmonary metastases.

Objective To assess the therapeutic outcomes of transcatheter arterial chemoembolization combined with percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis for primary hepatic carcinoma accompanied by portal vein tumor thrombus. Methods Thirty patients with primary hepatic carcinoma accompanied by portal vein tumor thrombosis of type Ⅱ and type Ⅲ were randomly divided into two groups. The Child-Pugh ratings (class A and B) of group A and B were 9 vs 9 (class A) and 5 vs 7 (class B) respectively (χ~2 = 0.201, P > 0.05). The constitution of Type Ⅱ and type Ⅲ portal vein tumor thrombus in group A and B were 8 vs 9 and 6 vs 7 respectively (χ~2 =0.002, P>0.05). The median values of ALT, TBIL, ALB and AFP in group A and B were 58.7U/L vs 70.5 U/L (W=191.5, P>0.05), 21.4 μmol/L vs 21.7μmol/L (W=203, P>0.05), 35.3 g/L vs 37.5 g/L (W = 214, P > 0.05) and 680 μg/L vs 873 μg/L (W = 179. 00, P > 0.05) respectively. Group A was treated with transcatheter arterial chemoembolization (TACE) using emulsion made up of adriamycin, cisplatin, mitomycin and ultraliquidlipiodol plus percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis using emulsion consisted of cisplatin and ultraliquidlipiadol, while group B was treated with TACE only as a control group. Survival analyses were performed via the Kaplan-Meier test in SPSS11.5 with the log-rank tests with an threshold of 0.05. Results The 3, 6 and 12 months survival cases of group A and B were 11 vs 10, 10 vs 3, and 7 vs 0 respectively. The median survival time of group A and group B were 14.0 months and 4.0 months respectively. The difference of the two groups was significantly (χ~2 =11.728, P<0.01). There was no severe side-effect related to therapy in both groups. Conclusion Comparing with the control group, TACE combined with percutaneous injection of chemoembolization agent intra-portal vein tumor thrombosis could significantly prolong the median survival time of patient with primary hepatic carcinoma accompanied by type Ⅱ and type Ⅲ portal vein tumor thrombosis.

Objective To investigate the application effect of stone basket in ureteroscopic holmium laser lithotripsy for treatment of upper ureteral calculi. Methods The clinical data of 96 patients with upper ureteral calculi were retrospectively analyzed, all patients underwent ureteroscopic holmium laser lithotripsy. Forty-eight cases used the stone basket in the operation process (observation group), and 48 cases did not use the stone basket in the operation process (control group). The operation time, length of stay, success rate of lithotripsy, stone residual rate and incidence of postoperative complication were compared between 2 groups. Results The patients of 2 groups successfully completed surgery. There were no statistical differences in operation time, length of stay and incidence of postoperative complication between 2 groups (P>0.05). The success rate of lithotripsy in observation group was significantly higher than that in control group: 97.92% (47/48) vs. 75.00% (36/48), and the stone residual rate was significantly lower than that in control group:4.17%(2/48) vs. 18.75%(9/48), and there were statistical differences (P<0.05). Conclusions The stone basket in ureteroscopic holmium laser lithotripsy for treatment of upper ureteral calculi can thoroughly remove stones. It reduces the incidence of residual stones, does not affect the safety of the operation, and has good clinical value.

Object To develop a new method of discriminating the principle components of Radix Paeoniae Rubra (RPR) from different areas, and to find the reason for forming high-quality of RPR in the place of the genuine. Methods Using Foruier transform infrared (FTIR) absorption spectrometry, the characteristic peaks of fingerprint infrared spectra of RPR samples from 18 habitats were recognized and compared. Results Frequency, intensity and shape of infrared absorption spectra were obviously different between wild and cultivated groups of RPR. The infrared absorption peaks of RPR in Duolun, a famous Chinese orthodox drug, were of distinct characteristics. Conclusion FTIR technique is first applied to rapid analysis of principle component of RPR from different areas. So an operable method in the quality control and discrimination of RPR in the place of the genuine is provided.
