Objective To compare the clinical curative effect of partial hepatectomy combined with biliary intestinal anastomosis and T tube drainage in the treatment of intrahepatic stones.Methods 72 patients with intrahe-patic stones were selected and randomly divided into observation group and control group.The observation group received lobectomy of liver +bile duct jejunum anastomosis,the control group received lobectomy of liver +T tube drainage treatment.The operation time,intraoperative blood loss,functional exercise time,length of hospital stay, recurrence rate,clinical efficacy and complications were observed.Results The patients were followed up for 6 -12months.The operative time,blood loss,ambulation exercise time,length of hospital stay in the observation group were (158.29 ±32.53)min,(161.42 ±11.75)mL,(3.61 ±0.28)d,(5.31 ±1.17)d,which were significantly more than those in the control group[(127.57 ±26.38)min,(78.29 ±8.36)mL,(2.25 ±0.56)d,(4.86 ± 2.39)d].The recurrence rate of stone of the observation group during the postoperative follow -up was 5.56%, which was significantly lower than 16.67% of the control group (t =4.328,7.196,2.174,2.259,1.862,all P <0.05).The excellent and good rate of the observation group was 94.44%,which was higher than 83.33% of the control group,the difference was statistically significant (χ2 =1.257,P <0.05).6 cases in the observation group had complications (16.67%),including 1 case of incision infection,subphrenic infection in 2 cases,bile leakage in 2 cases,1 case of pulmonary infection.15 cases in the control group had postoperative complications (41.67%), including 3 cases of wound infection,bile leakage in 4 cases,3 cases of biliary tract bleeding,abdominal bleeding in 1 case,2 cases of pulmonary infection,subphrenic infection in 1 case,pleural effusion in 1 case,the difference between the two groups was significant (χ2 =2.291,P <0.05).Conclusion Liver resection is an effective method for treatment of intrahepatic bile duct stones,on the basis of liver resection by intestinal anastomosis in the treatment of intrahepatic bile duct stone long -term effect is better,which can effectively prevent recurrence of the intrahepatic bile duct stone and bile duct cancer,widely used in patients with indications for clinical physicians.

Objective The purpose of this study was to investigate the preventive effect of flurbiprofen axetil or small-dose ketamine for remifentanil-induced postoperative hyperalgesia. Methods 120 anesthetized patients with ASA ⅠorⅡwere randomly divided into three groups. Group A (40 cases) was given 0.5 mg/kg of ketamine by intravenous injection,and 5μg/(kg.min) vein to maintain,group B (40 cases) was given 100 mg of preoperative flurbiprofen axetil by intravenous injection and group C (40 cases) had no flurbiprofen axetil or ketamine which was served as controls. After the treatment, all groups were given continuous intravenous tramadol controlled analgesia (PCIA) . Results After 1 h, 2 h, 4 h and 8 h, the visual analog scale (VAS) of group C was significantly higher than that of group A and group B ( <0.05);after 24 h, there was no statistically significant difference among the three groups in VAS scores ( > 0.05) . The number of fentanyl analgesia were 25 cases and postoperative 24 h PCIA self-control were (8.6 ±4.2) times, which were more than 7 cases and (3.3 ±2.8) times of group A, and 6 cases and (3.2 ± 2.2) times of group B ( <0.05) . Conclusion The preoperative administration of flurbiprofen axetil or intraoperative continuously administered ketamine is able to prevent the occurrence of remifentanil-induced postoperative hyperalgesia, and it will not affect the patient regained consciousness. The method is safe and reliable,so it is worth promoting and popularizing.

OBJECTIVE: To develop a HPLC method for the determination of the concentration of caffeic acid, chlorogenic acid and 1, 3-dicaffeoylquinic acid in rat urine and to observe the excretion of three compounds in rats. METHODS: Rat urine samples, collected at different intervals after vein injection of Dengzhanxixin injection traditional Chinese medicines, added with protocatechuic aldehyde as internal standard, handled by ethyl acetate, then were measured by HPLC. RESULTS: The recoveries of caffeic acid, chlorogenic acid and 1, 3-dicaffeoylquinic acid were about 95%-98%, 90%-95%, 95%-97%, respectively. The cumulative excretions of caffeic acid, chlorogenic acid and 1, 3-dicaffeoylquinic acid in urine within 60 h were (70.97 ± 7.31)%, (87.62 ± 12.23)% and (9.87 ± 2.63)%. Relative standard deviation(RSD) of intra- and inter-day assay was less than 10%. CONCLUSION: The established method is simple, accurate and specific.

This study aim to reveal the total pharmacokinetics of rhein and chrysophanol after oral administration of Quyu Qingre granules (QUQRG) in normal and acute blood stasis rabbits, to identify the pharmacokinetics differences between two groups of rabbits and to evaluate the applicability of the total statistical moment analysis. Based on the concentrations of rhein and chrysophanol in plasma determined by an established HPLC method, and the calculation of main total pharmacokinetic parameters, this study found that total pharmacokinetic parameters VRT, value of blood stasis group is lager than that of normal group and the difference is significant Compared with normal group, total pharmacokinetic parameters AUC,, MRT,, t1/2t, and Vt value of blood stasis group is lager, while the k, and CL, value is smaller. The findings indicated that the absorbed and released time of rhein and chrysophanol was accelerated and the total absorptive amount of these two compounds was increased in rabbits with acute blood stasis, compared with the normal rabbits. Total quantity statistical moment analysis can combine the pharmacokinetics of rhein and chrysophanol and express the pharmacokinetic behavior of these two compounds in QUQRG. The parameters in this paper can provide reference frames for the follow-up development of QUQRG.

Objective To calculate the mean absorbed doses at celluar and subcellular levels for uniformly and non-uniformly distributed Auger electron emitters. Methods The energy deposited in cell or nucleus by Auger electrons was analytically calculated using the polynomial representation of energy loss.S-values were subsequently computed for several target-source combinations.The absorbed dose and dose distribution were calculated for spherically symmetric radionuclide distributions depending linearly and exponentially on the radial position.The dose profile as a function of the source radial coordinate was also evaluated for typical cell sizes.The contributions of photon radiation to absorbed dose in cells were ignored. Results The mean absorbed dose and dose distribution depend largely on the size of target cells,the radiation spectrum and intracellular localization and distribution of radionuclides.The contribution of intranuclear radionuclides to mean absorbed dose was larger than that of extranuclear ones. Conclusion Auger electrons can produce high local energy deposition in cells because of their very low energies and extremely short ranges.Our dose calculation method is simple.The results are reliable and can be used in many fields.
