Abstract
OBJECTIVE To explore the effects of ranitidine on pharmacokinetics of rhein in rats after oral administration of Dachengqi Decoction (DCQD), a compound traditional Chinese herbal medicine. METHODS Twelve male Sprague-Dawley rats were divided into DCQD group and DCQD plus ranitidine group, and were orally administered with DCQD at a dose of 10 g/kg or DCQD (10 g/kg) combined with ranitidine (150 mg/kg), respectively. Blood samples were gathered after a series of time intervals. Metabolism of rhein was determined with a reversed-phase high-performance liquid chromatography with internal standard of 1, 8-dihydroxyanthraquinone and the data were analyzed with DAS 2.1 program. The pharmacokinetic parameters were compared between the two groups. RESULTS The pharmacokinetic parameters of rhein in the DCQD group, including peak concentration (C(max)), area under the plasma concentration-time curve (AUC), distribution phase half-life (t(1/2alpha)), elimination rate constant (K(10)) and central to peripheral transfer rate constant (K(12)), were significantly different to those in the DCQD plus ranitidine group (P<0.05, P<0.01). There were no significant differences in the other parameters between the two groups. CONCLUSION Ranitidine can influence the pharmacokinetics of rhein in rats after oral administration of DCQD.

Abstract
OBJECTIVE To explore the effect of acute pancreatitis (AP) on the pharmacokinetics of herbal ointment micron Liuhe Pill, MLHP) components in anesthetized rats. METHODS Rats were randomly divided into a AP model group (n=6) and a normal group as a control (n=6). The rat model of AP was induced by intraperitoneal injection of L-arginine in rats (15 mg/kg, twice, interval 1 h). Chinese herbal ointment MLHP was used externally on the belly after the 2nd injection for 48 h in both groups. Emodin, rhein, aloe emodin, physcion, chrysophanol from MLHP were detected and quantified in rat serum and pancreas (at 48 h) by high performance liquid chromatography-tandem mass spectrometry. RESULTS Among the five components, only emodin, aloe emodin and physcion from MLHP were detected in all rat serum and most of the rats' pancreas. Rhein and chrysophanol were not detected in both serum and pancreas. T1/2α of emodin and physcion in MLHP were obviously shorter in the AP model group than those in the normal group (P<0.05), while there was no difference for T1/2α of aloe emodin. The peak concentration and area under curve of all three components were much higher in the AP group than those in the normal group with MLHP in external application for 48 h (P<0.05). Furthermore, the mean residence time (MRT) and maximum plasma concentration (Tmax) of emodin and aloe emodin were obviously longer in the AP model group than those in the normal control group (P<0.05). There was no significant difference for Ka of all components between the two groups. Emodin could be detected in all rats' pancreas at 48 h in both groups, while its mean pancreatic concentration was higher in the AP model group than in the normal group (0.61±0.54 ng/mL, 0.42±0.37 ng/mL, respectively,P<0.05). Aloe emodin could be detected in all rats' pancreas at 48 h in both groups and their mean pancreatic concentration were similar (0.31±0.24 ng/mL, 0.33±0.17 ng/mL, respectively,P>0.05). Physcion could be detected in pancreas of most rats in the AP model while only two rats in the normal group. CONCLUSION AP could significantly affect the pharmacokinetics of absorbed components of Chinese herbal MLHP ointment in rats.

Abstract
BACKGROUND This study was aimed at determining the effects and safety of Da-Cheng-Qi decoction (DCQD) or DCQD combined with conservative therapy in patients with intestinal obstruction. MATERIALS AND METHODS PubMed, EMBASE, Cochrane Controlled Trials Register, and several other databases were searched. Randomised controlled trials (RCTs) of DCQD or DCQD plus conservative therapy in patients with intestinal obstruction were eligible. Therapeutic effect was estimated by the improvement of clinical manifestations and diagnostic imaging; dichotomous/ordinal data assessment of overall response to therapy, adverse effects; or continuous variable were identified, including time to first bowel movement, time to first flatus, length of hospital stay. RESULTS Sixty eligible RCTs including 6,095 patients were identified. Response rate: (1) DCQD versus conservative therapy (6 RCTs, 361 patients, RR of respond =1.13; 95% CI 0.97 to 1.31). (2) DCQD plus conservative therapy versus conservative therapy (48 RCTs, 4,916 patients, RR of respond =1.25 which favoured DCQD plus conservative therapy; 95% CI 1.20 to 1.30). Treatment effect remained similar when RCTs at high risk of bias were excluded. Time to first flatus postoperatively: (1) DCQD versus conservative therapy (2 RCTs, 240 patients, SMD=-3.65; 95% CI -8.17 to 0.87). (2) DCQD plus conservative therapy versus conservative therapy (11 RCTs, 1,040 patients, SMD=-2.09 which favoured DCQD plus conservative therapy; 95% CI -3.04 to -1.15). CONCLUSION DCQD combined with conservative therapy may increase the success rate of conservative therapy for intestinal obstruction significantly and can shorten the duration of postoperative ileus in patients undergoing abdominal surgery compared with conservative therapy alone.

Pharmacokinetic and pharmacodynamic comparison of chinese herbal ointment liu-he-dan and micron liu-he-dan ointment in rats with acute pancreatitis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:389576. [PMID: 24693322 PMCID: PMC3947679 DOI: 10.1155/2014/389576] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/15/2013] [Revised: 12/05/2013] [Accepted: 12/26/2013] [Indexed: 02/05/2023]
Abstract
Aim. To compare the pharmacokinetics and pharmacodynamics of herbal ointment Liu-He-Dan (LHD) and micron LHD (MLHD) in rats with acute pancreatitis (AP). Methods. Twenty rats were allocated into normal, AP, LHD, and MLHD groups. LHD or MLHD was applied on rats' abdomens. Plasma levels of emodin, rhein, aloe emodin, physcion, and chrysophanol were determined by high performance liquid chromatography-mass spectrometry-mass spectrometry (HPLC-MS-MS) at different time points, and the pharmacokinetic parameters were calculated. Serum amylase, TNF- α , IL-6, and IL-10 levels, and the pancreatic pathological scores were determined at 48 h after LHD or MLHD treatment. Results. T 1/2 α and area under the curve (AUC) of emodin in the MLHD group were lower than those in the LHD group, while T 1/2 α and AUC of aloe emodin in the MLHD group were higher than those in the LHD group (P < 0.05). T 1/2 α and T max of physcion in the MLHD group were significantly shorter than those in the LHD group (P < 0.05). Compared with the AP group, the amylase, malondialdehyde (MDA), TNF- α , and IL-6 levels decreased significantly after three days of treatment in LHD and MLHD groups, while the levels of superoxide dismutase (SOD), TNF- α , and the pancreatic pathological score, were similar. The pharmacodynamic parameters between the LHD and MLHD groups were similar. Conclusion. MLHD had better pharmacokinetics than, and similar pharmacodynamics to, LHD in the management of rats with AP, which indicated that MLHD might be substituted for LHD in the treatment of AP and thus reduce the amount of medicinal herbs used.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chinese herbal preparation of Liu-He-Dan ointment has been adapted for acute pancreatitis in external application for many years in West China. AIM OF THE STUDY To investigate the effect of acute pancreatitis on the pharmacokinetics of Liu-He-Dan ointment in rats while it was used externally on belly. MATERIALS AND METHODS Twelve male Sprague-Dawley rats were randomly divided into acute pancreatitis model group (n=6) and normal group as a control (n=6). Chinese herbal Liu-He-Dan ointment was used externally on belly. Emodin, rhein, aloe emodin, physcion and chrysophanol in plasma and pancreas (at 48 h) were detected and quantified by liquid chromatography-tandem mass spectrometry. Amylase in plasma were determined with iodide process. RESULTS Among the five components, only emodin, aloe emodin and physcion from Liu-He-Dan were detected in plasma and pancreas. The absorption of each component was tended to decrease in acute pancreatitis group after topically management with Liu-He-Dan ointment on rats' abdomen. The T(max), C(max) and area under curve (AUC) of each component were distinctly lower in AP group than those in normal group (p<0.05). However, the T(1/2α) and mean retention time (MRT) of emodin lasted longer in acute pancreatitis group than those in normal group (p<0.05). There was no statistical difference in the MRT of aloe emodin and physcion between the two groups. Emodin could be detected in all rats' pancreas at 48 h in both groups, while its mean pancreatic concentration was higher in acute pancreatitis model group than in normal group (0.91 ± 0.68, 0.41 ± 0.36, respectively). Physcion could be detected in pancreas of most acute pancreatitis models, but not in normal rats. Aloe emodin was found in all pancreas from acute pancreatitis models while only one in normal group. The level of amylase in Liu-He-Dan group was obviously lower than that in the AP model group (p=0.0055). CONCLUSION We concluded that acute pancreatitis may significantly affect the pharmacokinetics of Liu-He-Dan while external applied on belly, which indicated the dosage modification in AP. However, acute pancreatitis seems to promote the distribution of the detected components into pancreas. The ointment could help relieve the disease of pancreatitis.

Abstract
AIM: To investigate the effect of severe acute pancreatitis (SAP) on pharmacokinetics of Da-Cheng-Qi Decoction (DCQD) components in rats.
METHODS: Rats were divided into SAP group and sham-operation group as a control group (n = 6). Rhein, chrysophanol, rheochrysidin, magnolol, hesperidin and naringin in DCQD were quantified in rat serum by high performance liquid chromatography tandem mass spectrometry for studying their pharmacokinetics.
RESULTS: Early absorption of each DCQD component was tended to degrade in SAP group after treatment with DCQD by gavage. The Cmax (chrysophanol, P = 0.0059; rheochrysidin, P = 0.0288; magnolol, P = 0.0487; hesperidin, P = 0.0277; naringin, P = 0.0023) and AUC (rhein, P = 0.0186; chrysophanol, P = 0.0013; magnolol, P = 0.001; hesperidin, P = 0.0081; naringin, P = 0.0272) of DCQD component were obviously lower in SAP group than in control group. The T1/2α of chrysophanol and rheochrysidin (P = 0.0467 and 0.0005, respectively) and Tmax of chrysophanol and rheochrysidin (P = 0.0101 and 0.0037, respectively) lasted longer in SAP group than in control group.
CONCLUSION: SAP can significantly impact the absorption of DCQD components in rats and their pharmacokinetic parameters.
