AIM: To study the pharmacokinetics of flavonoids in mice after ig administration of Xiexin Decoction (Radix et Rhizoma rhei, Rhizoma coptidis, Radix Scutellariae). METHODS: Mice were given a single ig dose of Xiexin Decoction 4.5, 9.0 or 18.0 g/kg. Flavonoids in plasma were analysed by HPLC and plasma concentration of baibalin was determined. Pharmacokinetic parameters were calculated from the plasma concentration-time data with the DAS software package. RESULTS: After ig administration of Xiexin Decoction in mice, baicalin, baicalein and another flavonoid were detected in plasma and baicalin concentration was the highest of the three kinds of flavonoids in plasma. After a single ig dose of Xiexin Decoction 4.5, 9.0 or 18.0 g/kg, the pharmacokinetic parameters of baicalin were as follows:T_ 1/2 =2.77、5.69、6.20 h,AUC_ 0-∞ =9.09、23.49、39.57 ?g?h/mL,CL= 12.52 、 6.962 、 11.50 L?h/kg,V_d= 50.11 、 79.56 、 102.95 L/kg,C_ max1 =1.89、3.32、4.79 ?g/mL(T_ p1 = 0.08 h ), C_ max2 =1.46、2.57、4.16 ?g/mL(T_ p2 =3 h), respectively. CONCLUSION: Three kinds of flavonoids can be absorbed after ig administration of Xiexin Decoction in mice, of which baicalin is the major component.

Objective To investigate the effect of ellagic acid extracted from gallnut on multiple myeloma SP2 / 0 cell line and related mechanisms. Methods Multiple myeloma SP2 / 0 cell line was treated for 48 h with different concentrations of ellagic acid in vitro. Cell morphology,proliferation,apoptosis and cell cycle were analyzed with microscope,MTT experiment and flow cytometry,respectively. Tumor cell proliferation and apoptosis-related gene expression of COX-2 were detected by Western blotting. Results Cell cycle was arrested at the G1 phase 48 h after treatment with ellagic acid, the cell in G1 were (55. 21±3. 01)% , (64. 48 ± 0. 43)% , (75. 10 ± 2. 46)% , respectively, with significant difference as compared with control group [(34. 04±1. 74)% ,P<0. 01]. Cell suppression rate (21. 18±5. 92)% ,(44. 58±3. 43)% and (70. 15±2. 90)% ,respectively, in 20,40 and 60 μg·mL-1 ellagic acid treatment groups. Compared with the control group,the differences were significant (P<0. 01). Cell apoptosis rate was (9. 60 ± 0. 56)% , (19. 30 ± 1. 51)% and (35. 10 ± 5. 26)% , respectively, in 20,40 and 60 μg·mL-1 ellagic acid treatment groups,with significant differences as compared with the control group[(3. 23±0. 85)% ,P<0. 01].

MethodsNBNA was performed for 60 newborns with HIE within 12-14 days and DST was also performed at 6th month after birth.ResultsMild and severe degree HIE newborns with low NBNA scores had unfavorable prognosis. Conclusions NBNA and DST can provide evidence for early interference for newborn's HIE.

Objectives To study the status of medical compliance and the reason of non-medical compliance behavior of the Hui diabetics. Methods 121 Hui diabetics were recruited by convenient sampling, investigated by medical compliance questionnaire and interviewed by open questions about the reason of non-medical compliance behavior (e.g. drug therapy, diet therapy, sports therapy, self monitoring and periodic review). Results The mean score of the medical compliance behaviors was (32.69±8.64), and the overall rate of non-medical compliance was 95.9%(116/121) in Hui diabetics. Arranged by the rate of non-medical compliance in descending order, the five dimensions of medical compliance behaviors were sports therapy, self monitoring, periodic review, diet therapy and drug therapy in turn. The reason of non-medical compliance behavior mainly included the cognition of treatment, the economic conditions, job, minority customs and religion. Conclusions Non-medical compliance behaviors existed in five major diabetes therapies in the Hui diabetics. The patients and their families should be educated and conducted individually according to their specific situation to improve the medical compliance behavior.

Objective To investigate the diagnosis and treatment of primary hyperparathyroidism (PHPT) with urolithiasis.Methods The clinical data of 9 PHPT patients who were evaluated with simple metabolic evaluation in 881 urolithiasis from 2000 to 2005 were summarized and the references were reviewed.Results The level of serum calcium was (2.96±0.48)mmol/L before operation, (1.94±0.42) mmol/L after operation.The level of parathyroid hormone(PTH) was(1133.53±788.21)pmol/L before op-eration,(74.52±49.17)pmol/L after operation.The level of serum calcium and PTH changed significantly after the parathyroidectomy (P<0.01).Follow-up for 14 months to 6 years.the ureteral stones fragments with lithotripsy were clear after 3 months and followed without recurrence,although the renal stones without lithotripsy were followed with no significant change.Conclusions Increase of serum calcium or increase of PTH above double with normal serum calcium may be helpful for diagnosis of PHPT with urolithiasis.Ureteral stone with PHPT should be treated together.Renal stone with PHPT may be followed up after the parathv-roidectomy,and be treated until the complications were occurred.It suggests that the maidend diagnosed pa-tient with urolithiasis should be added with simple metabolic evaluation,including serum calcium, phospho-nium and PTH.
