Objective To investigate the biodistribution,excretion and other pharmacokinetics,of 188Re-1-hydroxy-1,1-ethylidene disodium phosphonate (HEDP) in cancer patients with osseous metastases who were suffering form bone pain. Methods A single dose (20,30,40,and 50 MBq/kg,10 patients in every group) of 188Re-HEDP was administered as a bolus injection,meanwhile dynamic images on patient's chest were collected for 30 min. Anterior and posterior whole-body images were obtained at 1,2,4,5,12,24,36,48,60 and 72 h after injection of 188Re-HEDP. By region of interest (ROI) technology,the curve of time-background corrected counts of left cardiac ventricle could be generated,and the background-corrected counts of various organs and total whole body could be calculated as a geometric mean using the anterior and posterior scans,and transformed to the percentage injected dose ( % ID). Urine was collected after injection of 188Re-HEDP. Counts of urine were measured by γ counter. Analysis of variance and t-test were used. Results Linear relationship of metabolism of 188Re-HEDP was observed in the doses from 20 to 50 MBq/kg,with correlation coefficient r2 = 0. 9376. A two-compartment model was the best fit for metabolism of 188Re-HEDP with the parameters median area under curve (AUC) 3.32 × 105,3.97 × 105,7.83 × 105,8.58 ×105,respectively; median α 0.06,0.05,0.04,0.06 respectively; median β 1.16 ×10-3,1.16 × 10-3,1.03 × 10-3,1.15 × 10 -3 respectively; median A 3591.21,4858.23,5642. 48,4167.05 respectively; median B 293.97,352.95,614.41,1063.82 respectively; median T1/2(α) 12.51,12.83,15.41,12.02 min respectively; median T1/2(β) 595.47,596.50,673.09,600.93 min respectively in the doses of 20,30,40and 50 MBq/kg. 188Re-HEDP was taken up mainly by bone up to 40% ID at 4 h. Urine profile showed that 66.79 % ID was eliminated within 24 h,being its 74% collected along the first 5 h after-administration.Conclusions In the doses of 20,30,40 and 50 MBq/kg,metabolism of 188Re-HEDP presented linear model. Pharmacokinetics of 188 Re-HEDP followed a two-compartment model administrated by blood vessel.Following injection,188 Re-HEDP was taken up mainly by bone and excreted by uropoietic system.

Objective To explore the effects of bilirubin on myeloid differentiation factor 88 (MyD88)and interleukin-1 receptor associated kinase-4(IRAK-4).Methods Seven-day-old Sprague Daw-ley rats (clean grade),male or female,weighing 12.0 to 15.0 g,were randomly assigned to 6 groups.There were normal saline group(Ⅰ),lipopolysaccharide(LPS)control group (LPS,Ⅱ),15 mg /kg bilirubin con-trol (free-LPS)group (Ⅲ),15 mg /kg group (Ⅳa),30 mg /kg group (Ⅳb)and 50 mg /kg group (Ⅳc), and then subsequently divided into 2 h,5 h and 24 h subgroups in each groups.Some of the 200 newborn rats died amid the experiment.Finally a total of 144 were involved in the analysis of results,and 8 rats in each subgroups.Newborn Sprague Dawley rats were administered at various doses of bilirubin (15 mg /kg, 30 mg /kg and 50 mg /kg respectively)intravenously;1 h after injection,the rats were administered LPS intrap-eritoneally at a dose of 1 mg /kg;MyD88 and IRAK-4 were detected by immunohistochemistry at 2 h,5 h and 24 h after the injection of bilirubin.Results (1 )LPS could stimulate the expression of MyD88 and IRAK-4 in spleen cells (qMyD88 2 h =49.89,qMyD88 5 h =139.54,qIRAK-4 2 h =7.93,qIRAK-4 5 h =24.30,qIRAK-4 24 h =6.97 ,P <0.01 ).(2)Low concentration of bilirubin could promote the expression of MyD88 and inhibit the ex-pression of IRAK-4 (qMyD88 2 h =0.76,qMyD88 5 h =5.05,qIRAK-4 2 h =6.43,qIRAK-4 5 h =22.37,qIRAK-4 24 h =1.50, P <0.01 ).(3)LPS stimulation MyD88 affected by low concentration of bilirubin was not obvious (q2 h =1.48,q5 h =1.45,q24 h =0.10,P >0.05).Effects of medium and high concentration of bilirubin on LPS stim-ulation MyD88 were inhibitory(qⅣb 2 h =42.87,qⅣc 2 h =51.38,qⅣb 5 h =103.61 ,qⅣc 5 h =1 15.44,qⅣb 24 h =1.18,qⅣc 24 h =1 1.66,P <0.01 ).(4)Effects of low,medium and high concentration of bilirubin on LPS stimulation IRAK-4 were inhibitory(qⅣa 2 h =9.52,qⅣb 2 h =14.39,qⅣc 2 h =25.55,qⅣa 5 h =38.83,qⅣb 5 h =54.62,qⅣc 5 h =60.51 ,qⅣa 24 h =2.41 ,qⅣb 24 h =1.47,qⅣc 24 h =7.61 ,P <0.01 ).(5)The inhibition of biliru-bin to MyD88 and IRAK-4 was observed at 2 h,strengthened at 5 h,disappeared at 24 h in low-mid concen-trations of bilirubin(P <0.01 )while still visible at 24 h in high concentration of bilirubin.(6)There was neg-atively correlation between the expression level of MyD88,IRAK-4 and bilirubin concentration(rsMyD88 2 h =-0.86, rsMyD88 5 h =-0.92,rsMyD88 24 h =-0.53,rsIRAK-4 2 h =-0.82,rsIRAK-4 5 h =-0.86,rsIRAK-4 24 h =-0.57,P <0.01).(7) Under the effect of bilirubin and LPS,there were positively correlation between the expression levels of MyD88 and IRAK-4 of spleen cells(r2 h =0.77,r5 h =0.9,r24 h =0.67,P <0.01).Conclusion Bilirubin could inhibit the expression of MyD88 and IRAK-4.As the concentration of bilirubin increasing,its inhibition is more obvious and prolonged.The mechanism that bilirubin affects immune function of newborn rat may be related to regulation of expression of MyD88 and IRAK-4 at toll-like receptor 4 signal pathway.

Objective To study the tolerance to 188Re-1-hydroxy-1 ,1-ethylidene disodium phosphonate(HEDP) in patients with bone pain caused by osseous metastases. Methods Thirty-one patients(10with prostate cancer, 9 with breast cancer, 3 with lung cancer, 5 with liver cancer, 2 with rectal cancer, 1with esophageal cancer and 1 with renal cancer) received a single injection dose of 188Re-HEDP. The patients were divided into four groups according to the injection dose: 20 MBq/kg (6 patients), 30 MBq/kg(6 patients), 40 MBq/kg (9 patients), and 50 MBq/kg (10 patients). Haematological toxicity (WHO grading) of grade Ⅲ- Ⅳ was considered unacceptable. Vital signs and adverse effects after injection were recorded for 8 weeks. Blood counts were measured weekly during a period of 8 weeks. Biochemical parameters and electrocardiogram were assayed at week 4 and 8. Statistical analysis was performed for per-protocol (pp) population (t-test). Results Twenty-seven patients belonged to PP population with 5 in the group of 20 MBq/kg, 5 in the group of 30 MBq/kg, 8 in the group of 40 MBq/kg and 9 in the group of 50 MBq/kg.No obvious adverse effects and no significant change of vital signs, electrocardiogram, liver and renal function were found after injection. Alkaline phosphatase was slightly higher than baseline at week 4 and 8 after therapy, but the difference was not statistically significant. In the 20 MBq/kg group, reversible grade Ⅰ leucopenia was noted in 1 patient. In the 30 MBq/kg group, 2 patients showed reversible grade Ⅰ leucopenia including 1 alone with reversible grade Ⅲ thrombopenia. In the 40 MBq/kg group, reversible grade Ⅰ leucopenia and thrombopenia was observed in 1 patient and reversible grade Ⅱ leucopenia and thrombopenia in another patient. In the .50 MBq/kg group, 3 patients showed reversible grade Ⅱ leucopenia. The lowest level of thrombopenia was at week 4(143.5 × 109/L), leucopenia at week 6 (5.4 × 109/L) and anaemia at week 8(t = 3.1325, 3.3156, 3.4917, all P ＜ 0. 05 compared with baseline). At week 8, the mean level of platelet and leucocyte recovered to baseline. "Bounce pain" was found in 2 of 27 patients (7.41%).Conclusions The dose of 20 MBq/kg, 30 MBq/kg, 40 MBq/kg or 50 MBq/kg of 188Re-HEDP do not cause significant side effects on cancer patients with bone metastases, though there is a tendency that the haematological toxicity may increase as the dose of 188Re-HEDP increases.

To investigate me material basis of Mahuang Fuzi Xixin decoction (MFXD) for anti-inflammation and immune-suppression based on the combined method of serum chemical and serum pharmacological. The LC-MS/MS fingerprints of MFXD, drug-containing serum and blank serum were compared to define the components in plasma. Histamine, β-hexosaminidase released from RBL-2H3 cell infulenced by drug-containing serum at different time points were measured by ELISA. The effect of drug-containing serum on lipopolysaccharide-induced splenocyte proliferation at different time points were determined by MTT. A correlation analysis was made on components of MFXD and pharmacological indexes based the stepwise regression method. After the intragastrical administration with MFXD, 32 components were discovered in rat serum, including 27 prototype components (10 from Mahuang, 13 from Fuzi and four from Xixin) and five unknown components. Compared with blank serum, drug-containing serum could reduce the release of histamine from RBL-2H3 induced by antigen at different time points (P < 0.05); except the 4-hour drug-containing serum, all of the remaining drug-containing serums could inhibit the RBL-2H3 mastocyte degranulation induced by antigen at different time points (P < 0.05). Drug-containing serum could significantly lipopolysaccharide-induced mouse splenocyte proliferation at 15 and 30 min (P < 0.05). A regression analysis was made on the chemical data of components absorbed into blood and pharmacological indexes, i. e. release rate of histamine, release rate of β-hexosaminidase and inhibition rate of splenocyte. This suggested the close correlations among methyl pseudo-ephedrine, pseudoephedrine and histamine released from RBL-2H3 induced by antigen; pseudoephedrine, hypaconine, methyl pseudoephedrine and β-hexosaminidase released from RBL-2H3 induced by antigen; as well as benzoyl hypaconine, benzoylaconine, 14-benzoyl-10-OH-mesaconine, mesaconine and lipopolysaccharide-induced mouse splenocyte proliferation. Methylpseudoephedrine, pseudoephedrine, benzoyl hypaconine, benzoylaconine and mesaconine may be part of material basis of MFXD on anti-inflammation and immune suppression.
