Praziquantel ( PQT ) concentrations in plasma after iv 20 mg/kg decayed rapidly with tip of 0.36 h. The absorption of PQT was rapid following the intramuscular doses of 10,20,40mg/kg or intragastic dose of 100mg/kg, but the phase of elimination was much longer than that after iv. Both of MAT1m and MATig were greater than MRTiv. The bioavailability of ig was 13.2%, suggesting a strong first-pass effect. The kinetics of PQT elimination was linear after intramuscular dose of either 10 or 20 mg/kg, but nonlinear process was found when the dose was increased to 40mg/kg.By any route of iv, im and ig administration, the concentrations of PQT in the bile were much lower than the peripheral plasma concentrations and changed in parallel to the later with high levels after iv, medium levels after im and much low levels after ig.

DPP-4 inhibitors are new oral hypoglycemic drugs and hot spots developed and launched in recent years, and they pro-vide new choices for the clinical treatment of type 2 diabetes. In China, DPP-4 inhibitors that are approved to use in the treatment of type 2 diabetes are all imported products currently. In the paper, the current intellectual property situation of DPP-4 inhibitors that are developed and approved at home and abroad is researched and analyzed. Reasonable use of the patent information of DPP-4 inhibitors that is about to expire or have failed can provide good guidance for the subsequent development of DPP-4 inhibitors in domestic with promising curative effect and good market prospects, and can generate new patents in order to enhance the market competitiveness.

Objective To explore the application value of 320-slice spiral CT myocardial perfusion technique in the evaluation of cardiac function in patients with coronary artery disease.Methods 24 patients with known reversible myocardial ischemia with coro-nary heart disease and 13 cases of normal were detected by 320-slice spiral CT myocardial perfusion scan in resting and after dobu-tamine-induced stress,measured the values of cardiac function indexes(ESV、EDV、SV、EF)in resting and after dobutamine-induced stress respectively,the results were analyzed by paired t test and independent sample t test,when the P value is less than 0.05,con-sidered statistically significant or correlation.Results The values of cardiac function indexes (ESV,EDV,SV)between the resting and after dobutamine-induced stress were significantly different except EF value in normal group.But only the EF value was signifi-cantly different in CHD,the rest values of cardiac function indexes(ESV,EDV,SV)no significant difference.Each corresponding value of cardiac function indexes in resting and after dobutamine-induced stress was significantly different between the CHD and the normal.Conclusion The dobutamine-induced stress myocardial perfusion with 320-slice spiral CT can judge the impaired degree of cardiac function in patients with myocardial ischemia,provide the basis for comprehensive evaluation of coronary artery disease and its prognosis.

Objective To analyze the relationships between the drinking water fluoride and bone mineral density (BMD), and serum osteocalcin (BGP) and to explore the BMD and serum BGP as significant early screening biomarkers for fluorosis especially for early bone damage in endemic fluorosis areas. Methods Wamiao (severe endemic fluorosis area, as fluoride exposed group) and Xinhuai (non endemic fluorosis area, as control group) Village were selected in 2006. One hundred and fouty-six objects were chosen from 2 villages (103 in Wamiao, 43 in Xinhuai). The sex, age, body height, body weight, drinking water fluoride in each object's household well, BMD, and serum BGP were investigated, and the dose-response relationships were analyzed between the drinking water fluoride and BMD, and serum BGP. CurveExpert 1.3 Software was used to fit the dose-response relationships between the rate of abnormal BMD, the rate of abnormal serum BGP, and the drinking water fluoride. Results The levels of drinking water fluoride in males' and females' families in fluoride exposed group were [(2.38±0.68), (2.62±0.91 )mg/L] significant higher than that in control group [(0.35±0.08), (0.36±0.07)mg/L], the difference being statistically significant(t values were 14.27 and 11.08,and P<0.01, respectively). BMD in males in fluoride exposed group [(0.78±0.07)g/cm2] was significant lower than that in control group[(0.83±0.08)g/cm2], the difference being statistically significant (t=2.37,P<0.05). Serum BGP in males and females in fluoride exposed group [(4.17±0.67), (4.11±0.57) μg/L] were significant higher than that in control group [(1.48±0.40), (1.44±0.39)μg/L], the difference being statistically significant (t values were 17.64 and 19.40, and P<0.01, respectively]. BMD in the group with drinking water fluoride≥2.92 mg/L[(0.66±0.15 )g/cm2] was significant lower than that in the group with drinking water fluoride<0.42 mg/L [(0.76±0.12)g/cm2], the difference being statistically significant (P<0.01). The levels of serum BGP in the groups with the drinking water 0.42-,2.05-, ≥.92 mg/L[(3.83±1.07), (4.22±0.72), (3.99±0.63) μg/L] were significant higher than that in the group with the drinking water<0.42 mg/L [(1.44±0.37) μg/L], the difference being statistically significant (P<0.01). The equation for the dose-response relationship between the drinking water fluoride and the rate of abnormal BMD was y=(0.284-0.058x)-1.260, r=0.999 94; and y=100.05/(1+78.62e-4.5x), r=0.999 99 for the drinking water fluoride and the rate of abnormal serum BGP. Conclusions There were significant dose-response relationships between drinking water fluoride and BMD and serum BGP. It indicated that BMD and BGP might be considered as early screening biomarkers for endemic fluorosis, especially for the bone damage.

Objective To evaluate hemodynamic changes in liver treated by transjugular intrahepatic portosystemic stent-shunt(TIPSS)with hepatic computed tomography(CT)perfusion,Doppler ultrasound and portal vein pressure measurement,as well as the correlation among these methods.Methods Hepatic CT perfusion was performed in 9 cirrhotic patients one week before TIPSS and 72 hours after TIPSS. Intraoperative portal vein pressure was measured before and after portosystemic shunt establish.The follow- up hepatic CT perfusion were carried out in 3 cases at 3 months and 6 months postoperatively.The hemodynamic surveillance by Doppler ultrasound were performed in 48 hours and 3 months after TIPSS for 9 cases,and in 6 months after TIPSS for 6 cases.Two cases underwent venography and portal vein pressure measurement in 6 months after TIPSS treatment.Results The mean of portal vein perfusion(PVP),total hepatic blood flow(THBF),hepatic perfusion index(HPI)and portal vein free pressure(PVFP)before TIPSSwere(0.92?0.18)ml?min~(-1)?ml~(-1),(1.28?0.17)ml?min~(-1)?ml~(-1),(28?8)%,and (23.92?0.86)mmHg,respectively.In 72 hours after TIPSS,the mean of PVP,THBF,HPI and PVFP were(0.21?0.15)ml?min~(-1)?ml~(-1),(0.74?0.18)ml?min~(-1)?ml~(-1),(74 +13)%,and (12.62?1.54)mm Hg,respectively.After treatment,the mean of PVP was(0.49?0.05)ml?min~(-1)? ml~(-1)at 3 months and(0.57?0.03)ml?min~(-1)?ml~(-1)at 6 months,respectively.There was negative correlation between PVP and PVFP before TIPSS(r=0.678,P0.05).Moreover,a signifieant correlation was found between the degree of portal vein pressure decrease and portal vein perfusion decrease(r=0.867,P
