ABSTRACT
OBJECTIVE:To evaluate the pharmacoeconomics of pantoprazole vs. ranitidine in the treatment of gastricesophagitis reflux disease(GERD). METHODS:Retrieved from PubMed,EMBase,The Cochrane Library,CNKI,VIP and Wanfang database, RCTs about pantoprazole vs. ranitidine in the treatment of GERD were selected until Sept. 2014. Two reviewers independently screened literature in accordance with the inclusion and exclusion criteria,and extracted the data of included studies. Stata 12.0 soft-ware was used to estimate therapeutic efficacy index and cost,and cost-effectiveness analysis was performed with the decision tree model. RESULTS:A total of 7 RCTs were included,involving 1 389 patients. Cost-effectiveness analysis showed that for gradeⅠ-Ⅲ(by Savary-Miller standard)GERD,cost-effectiveness ratios of ranitidine were all lower than those of pantoprazole(gradeⅠ:18.86 vs. 57.93;gradeⅡorⅢ:35.58 vs. 146.13);gradeⅠ,Ⅱ,Ⅲincremental cost-effectiveness ratio(ICER)were 335.53,349.85,349.85. Sensitivity analysis supported this conclusion. CONCLUSIONS:Ranitidine is more economic therapy plan for gradeⅠ-Ⅲ GERD, but its ICER fluctuates greatly. Individual therapy plan should be formulated according to disease condition and economic condition.

ABSTRACT
Objective To investigate the role of nuclear factor(erythroid?derived 2)?like 2(Nrf2)in load?driven bone metabolism in Nrf2 knock?out(KO)mice. Methods The hybridized mice in the same brood were selected through PCR detection and were divided into two groups,i.e.,the Nrf2 knockout(KO)group and the wild?type(WT)group. Ulna of mice was loaded with 4 000 peak microstrains at 2 Hz for 3 consecutive days (120 cycles/day)as scheduled,the relative mineralizing surface(rMS/BS)and the relative bone formation rate(rBFR/BS)of ulna were measured for the two groups. Results Load?induced bone formation was suppressed in KO mice. Compared to the WT control,the relative bone formation rate was roughly 84%lower in KO mice(P<0.01). Conclusion The loss?of?function mutation of Nrf2 in bone diminishes load?driven bone formation.
ABSTRACT
Objective To explore the outcomes of the transplanted kidney as donor for clinical renal transplantation and summarize experience in combination with related literature.Method This study retrospectively analyzed the clinical documents of one case of uremia receiving renal allograft transplantation with the transplanted kidney as the donor in one case of renal transplantation after brain death in February,2015.The donor was a 31-year-old man who received renal transplantation for uremia in November,2014 and obtained normal renal function.Two months later,the patient was brain dead because of neurologic disorder and donated his transplanted kidney.The serum creatinine of the donor was 167 μmol/L,and the glomerular filtration rate was about 35 mL/min befor donation.The recipient was 27 years old who needed transplantation because of chronic renal function failure and uremia.Preoperation tests showed that PRA was negative,and serum creatinine was 1 353 μmol/L.After separating and dissecting the donor kidney carefully,we perfused and compensated the kidney by Lifeport Organ Perfusion and Preservation Conveyor.The warm ischemia time was about 15 min.The renal vein of the donor was anastomized with right external iliac vein of the receptor,artery with right external iliac artery,and ureter with right centrifugal ureter.Result The operating time was more than 3 h.Postoperatively,the recipient was given the immunosuppressive regimen as tacrolimus,mycophenolate mofetil and methylprednisolone to prevent rejection.At 1 st day postoperation,the 24-h urine volume of the receptor was 5 000 mL,serum creatinine was declined gradually to a minimum of 180μmol/L,and there was trace urine protein.The renal function of patient recovered well by now.Meanwhile,the patient was still under the follow-up.Conclusion It is practical that using transplanted kidney as donor kidney for re-transplantation.There were certain clinical significance for shortening the waiting time of renal transplantation in uremia patients and relieving the shortage of transplant kidney.

ABSTRACT
Objective To evaluate the role of transarterial chemoembolization (TACE) as an adjuvant therapy in patients with hepatocellular carcinoma (HCC) treated with hepatectomy. Methods Clinical data of 386 consecutive patients who underwent hepatectomy for HCC were analyzed retrospectively.Of the 386 patients, 156 patients did not undergo TACE served as controls (non-TACE group), the remaining 230 patients underwent TACE (TACE group) preoperatively (n=71), postoperatively (n=86), or both (n =73). For the purpose of comparison, patients who did not undergo preoperative TACE were assigned to group A (n=242), and those patients who underwent preoperative TACE were assigned to group B (n =144). Patients cumulative survival rates were calculated by survival table and analyzed using Kaplan-Meier survival curves. Results There were significantly higher complete necrosis rates in group B (18/144) than those in group A (0/242) ( P ＜ 0.01). The difference between the survival rate of patients with complete necrosis and those with incomplete necrosis was statistically significant (P＜0.01).The 1-,3-,5-and 10-year survival rates were 90.4%(66/73),72.9%(42/73),51.9%(22/73) and 25.4%(2/73) in combined TACE group, 74.0% (50/71) ,46.2%(28/71) ,27.3%(5/71) and 0(0/71) in preoperative TACE group, 88. 0% (73/86) ,59. 6% (39/86) ,36. 7% (11/86) and 0(0/86) in postoperative TACE group, and 75. 8% (110/156), 63.4% (48/156), 31.0% (13/156) and 23.9% (10/156) in non-TACE group,respectively. Combined TACE group got a significantly higher survival rate compared with non-TACE group or preoperative TACE group or postoperative TACE group (P＜0.05). The survival rates in either preoperative or postoperative TACE group were not significantly better than those in non-TACE group (P＞0.05).Conclusions As an adjuvant treatment, combined pre-and post-operative TACE can increase survival rate in patients with surgically resectable HCC. No significant benefit for patient's long term survival when either preoperative or postoperative TACE was performed in addition to surgery.
ABSTRACT
Objective To investigate the short term effect of licartin transarterial infusion in combination with chemoembolization (LTACE) and compare its effect with conventional transcatheter arterial chemoembolization (TACE) for advanced hepatocellular carcinoma (HCC).Methods Seventy-two cases of advanced HCC were included in this analysis.There were 50 males and 22 females with the average age of (58±12) yrs (range 34-86 yrs).Twenty-nine patients received LTACE treatment while the other forty three patients received conventional TACE treatment.Before intervention,there was no variation (P>0.05) in gender (X2 =0.202),Child-Pugh grading for hepatic function (X2=2.428),as well as in white blood cell count (t=1.101)and platelet count (t =0.080) between the two groups except for age and portal vein thrombosis.For LTACE group,30 minutes after the infusion of licartin (27.75 MBq/kg) into proper hepatic artery,an emulsion of 40 rag pharmorubicin and 30 ml uhrafluid lipidol was infused until hemostasis within target artery.For TACE group,only an emulsion of 40 nag pharmorubicin and 30ml uhrafluid lipidol was infused until hemostasis within target artery.Following these interventions,the two groups were given the same treatment to stabilize hepatic function and relief embolization-relating symptoms; Patients' follow-up included clinical symptoms and signs,hepatic and renal function,peripheral blood test,CT and radionuclide study(ECT).All data were analyzed with SPSS 11.5.Measurement data were expressed with mean and processed by t test; numeration data were processed by Chi square test and Fisher precise test; Kaplan-Meier analysis and log-rank test were applied for comparing the survival rate of the two groups.P <0.05 means the exist of a statistic variation.Results After treatment,there was no variation of Albumin,GPT,serum bilirubin,white blood cell,platelet and serum creatinine level between the two groups [t=0.250,0.907,0.629,0.005,0.250,0.453 (7 days) and 0.978,1.250,1.942,0.733,0.315,1.243 (14 days); P >0.05].ECT imaging demonstrated a 55.17% (16/29) uptake ratio of licartin within tumor areas by the time of 7-days follow-up study.The lesions in both LTACE and TACE groups exhibited a decrease in their size and statistically significant difference was demonstrated before and after treatment in either group( t=7.207,8.006,P <0.01).But between the two groups,the tumor size reduction showed no statistical difference,the tumor size in LTACE and TACE groups were( 1.68±0.32),(1.74±0.31)respectively (t =0.786,P>0.05)before treatment and(1.52±0.38),(1.61±0.36) respectively(t=0.891,P>0.05) after treatment.There was no variation between the two groups comparing the 6 months cumulative survival rate(LTACE 52%,TACE 76%,log-rank test,X2=3.080,P >0.05).Conclusion There was no statistically significant differences between LTACE and TACE groups concerning the short term effect and adverse reaction for treatment of advanced HCC.The long term outcomes should be established on the basis of a large-sample,multiconter,randomized trail.
ABSTRACT
Objective To explore a safe and effective hyperthermia interventional therapy temperature for hepatic carcinoma. Methods Eight swines were divided into four groups according to trans-arterial hyperthermic perfusion temperature, 45 ?C , 50 ?C ,55 ?C , and 60 ?C (catheter flowing temperature) groups. The hepatic and renal functions and blood coagulation function were examined before and after the procedur and then all swines were sacrificed and the livers were pathologically analysed,simultoneously with the evaluation of the safe hyperthermic temperature 35 hepatic carcinomas were carried out under this interventional hyperthermochemotherapy via the arterial catheter (80 cm, 5F) placed into the tumoral artery with the perfusion agents warmed to 60～65 ?C (catheter flowing temperature was 47.55?0.44 ?C ). Results The hyperthermic coagulation necrosis, hepatic dysfunction level and fever were found after 55 ?C and 60 ?C hyperthermic perfusion while those of 45 ?C and 50 ?C groups basically remained normal. The tumor growth rate and total efficacy rate were -(0.35?0.32) and 79.2%, respectively, and 0.5, 1, 1.5 year survival rates were 100%, 80%, 60% respectively after follow-up. The adverse effects of the interventional hyperthermochemotherapy was similar to the routine TACE. Conclusions 45 ?C and 50 ?C (catheter flowing temperature) hyperthermochemotherapy for hepatic carcinoma is safe and effective.
