AIM:To study the urinary pharmacokinetics of five anthraquinones after oral administration of Xiexin Decoction(Radix et Rhizoma rhei,Rhizoma coptidis and Radix scutellariae) in rats.METHODS:A high-performance liquid chromatographic method with fluorescence detection(HPLC-FLD) was established and validated the quantification for five anthraquinones(aloe-emodin,rhein,emodin,chrysophanol and physcion) in rat urine.SD rats were given 12 g/kg of Xiexin Decoction.Urine was collected before and after perfusion.Anthraquinones components in urine were measured by HPLC-FLD.Urinary pharmacokinetic parameters were determined according to urinary output-time data.RESULTS:After oral administration of Xiexin Decoction all the five anthraquinones were excreted from the urine.The excretion T_ 1/2 of aloe-emodin,rhein,emodin,chrysophanol and physcion were 3.46?1.18,3.24?0.60,4.69?1.99,4.49?1.63,5.65?1.74 h,respectively.The amounts of aloe-emodin,rhein,emodin,chrysophanol and physcion excreted from urine during 0～48 h were(11.28?4.30)?g,(116.73?17.46)?g,(5.48?2.92)?g,(9.53?2.67)?g,(0.41?0.20)?g,respectively.CONCLUSION:After oral administration of Xiexin Decoction five anthraquinones were excreted from urine and a small quantity of five anthraquinones excreted from urine in rats is less than 10% of oral dose.

Objective To investigate the clinical efficacy of laparoscopic versus open omental patch repair for perforated peptic ulcer. Methods One hundred and twenty-seven patients who underwent omental patch repair for perforated peptic ulcer were analyzed retrospectively. There were 74 cases in the laparoscopic repair group (LR group) and 53 cases in the open repair group (OR group) respectively. Operative time, intraoperative blood loss,postoperative pain at 1 d and 3 d.time to first flatus and resumption of diet, time to drainage removal,surgical site infections (wound infection and intra-abdominal abscess),systemic complications and length of postoperative hospital stay were compared. Results LR group experienced less intraoperative blood loss[(32.7 ±25.6) ml], lower postoperative pain at 3 d[(2.8 ±1.5) scores], earlier time to first flatus [ (25.8 ± 20.1) h] and resumption of diet [ (2.7 ±2.1) d ], shorter time to drainage removal [(2.0±1.5) d], less wound infection (0) and shorter hospital stay[(4.8 ±2.3) d] than those in OR group [(53.2±30.0) ml, (36.9±27.9) h, (3.7±2.0) scores, (3.6±2.3) d,(2.9±2.2) d,9.4%(5/53), (6.6±4.0) d](P< 0.01 or <0.05). There were no significant differences in operative time,postoperative pain at 1 d, incidence of intra-abdominal abscess and systemic complications between the two groups. There were no suture-site leakage, reoperation and death in two groups. Conclusions Laparoscopic omental patch repair for perforated peptic ulcer is safe and efficacious. It has significant advantages over open approach with respects of less postoperative pain,earlier return of bowel function,less wound infection and shorter hospital stay.

Objective To explore clinlical outcomes of using improved computer-assisted fluoroscopic navi-gation to guide the percutaneous vertebroplasty to treat multiple osteoporotic spinal compression fractures. Methods Twenty-eight multiple osteoporotic spinal compression fractures patients with 73 painful vertebral body were got an-terio posterior,lateral and oblique radiographic imaging by using computer-assisted fluoroscopic navigation to imitate anterior- posterior.

It is a safe,precise,minimally invasive method.

Objective To analyze the changes of celluar and humoral immunity in children with juvenile idiopathic arthritis(JIA),as well as the changes in different subtypes,and to investigate the role of cellular and humoral immunity in the pathogenesis of JIA.Methods Ninety-two JIA subjects and 82 controls(healthy children) were included into this study.The levels of T lymphocyte subsets,natural killer (NK)cells,and B cells were analyzed by using flow cytometry.The serum interleukin-1 (IL-1),tumor necrosis factor-α (TNF-α),interleukin-l0 (IL-10),transforming growth factor-β(TGF-β) levels were detected by using enzyme-linked imnmunosorbent assay (ELISA).The serum IgG,IgM,IgA and C3,C4 levels were detected by using velocity scatter turbidimetry.Independent t-test,One-Way ANOVA test and Pearson analysis were adopted for data analysis.Results 1.In the group of JIA,the levels of CD3,CD4,IL-1,TNF-α,IgG,IgM,IgA and C3 were higher than those in the control group(all P ＜ 0.05),while the levels of CD4CD25,CD8,NK cells,IL-10 and TGF-β were lower than those in the control group(all P ＜0.05),and the ratio of CD4/CD8 was higher than that in the control group (P ＜ 0.05).2.In the group of systemic-onset JIA (so-JIA),the levels of CD4,IL-1,TGF-β,IgG,IgM,IgA,C3 and the ratio of CD4/CD8 were higher than those in the oligoarthritis JIA group(all P ＜ 0.05),while the levels of CD4CD25,CD8,IL-10 were lower than those in the oligoarthritis JIA group(all P ＜ 0.05).In the group of polyarthritis JIA,the levels of IL-1,TNF-α,IgG,IgM and IgA were higher than those in the oligoarthritis JIA group(all P ＜0.05),while the levels of CD4CD25,CD8,IL-10 were lower than those in the oligoarthritis JIA group (all P ＜ 0.05) ; In the group of so-JIA,the levels of CD4,TGF-β,C3 and C4 were higher than those in the polyarthritis JIA group (all P ＜ 0.05).3.The value of IL-1,TNF-α were positively correlated with that of C-reactive protein (CRP),erythrocyte sedimentation rate(ESR) in the JIA group(all P ＜ 0.05),while the value of IL-10,TGF-β was negatively correlated with that of CRP,ESR(all P ＜ 0.05).Conclusions There are cellular immunity and humoral immunity disorders in the JIA.Cellular immunity and humoral immunity are all involved in the pathogenesis of JIA.T helper cells are activated and Th1 cytokines increase,suppressive T cells,regulatory T cells impairment and suppressive cytokines decrease but immunoglobin increase,which involve in auto inflammation reaction and articular destruction in JIA.The immunity disturbances are more striking in so-JIA and polyarthritis JIA.IL-1,TNF-α,IL-10 and TGF-β are correlated with the disease activity.

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.

This article was aimed to study the antioxidant and antihyperlipidemic effect of total phenolic composition prepared from pineapple (A nanas comosus L.) leave. It had a rapid absorption after intragastric administration and the principle ingredient, p-coumaric acid, reached the peak concentration after 5 minutes of administration. The mice model with single intragastric administration of lipid and glucose were used in the observation of changes on postprandial glucose, lipid and intestinal lipase at different time points after drug administration. The results showed that phenols of pineapple leave can inhibit triglyceride and glucose absorption in certain extent. No significant effect was observed on inhibition at 30 minutes after the phenol administration. However, the intestinal lipase activity was obviously inhibited in normal mice and the intestinal lipase activity decline caused by acute lipid consumption can be reversed. It was concluded that the phenols pineapple leave may inhibit the absorption of lipids with correlation to lipase activity. It had certain regulation effect on the high postprandial glucose and fat absorption.
