Abstract
BACKGROUND The majority of global population suffer from various functional gastrointestinal disorders. Pugionium cornutum (L.) Gaertn. (PCG) is used to relieve indigestive symptoms in traditional Chinese medicine. However, little is known about the effects of bioactive components from PCG extracts on gastrointestinal motility. METHODS Crude ethanol extract of PCG (EEP) was prepared from Pugionium cornutum (L.) Gaertn. Different solvents were used to prepare fine extracts from EEP, including water extract of PCG (WEP), petroleum ether extract of PCG (PEEP), dichloromethane extract of PCG (DEP) and ethyl acetate extract of PCG (EAEP). Smooth muscle cell model and colonic smooth muscle stripe model were used to test the bioactive effects and mechanisms of different PCG extracts on contraction and relaxation. Diverse chromatographic methods were used to identify bioactive substances from PCG extracts. RESULTS EEP was found to promote the relaxation of gastric smooth muscle cell and inhibit the contraction of colonic smooth muscle strip. Among the fractions of EEP, EAEP mainly mediated the relaxation effect by stimulating intracellular calcium influx. Further evidences revealed that EAEP was antagonistic to acetylcholine. In addition, COX and NO-GC-PKC pathways may be also involved in EAEP-mediated relaxation effect. Quercetin was identified as a bioactive compound from PCG extract for the relaxation effect. CONCLUSION Our research supports the notion that PCG extracts promote relaxation and inhibits contraction of gastrointestinal smooth muscle at least partially through the effect from quercetin.

Comparative pharmacokinetics of (S)-MP3950, a novel 5-HT4 receptor agonist, in normal and atropine-induced gastrointestinal motility disorders rats. Xenobiotica 2017; 48:824-830. [PMID: 28786731 DOI: 10.1080/00498254.2017.1365974] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/07/2023]
Abstract
1. (S)-MP3950 is the (S)-enantiomer of active metabolite of mosapride, which exhibits higher 5-HT4 receptor agonistic effect than mosapride. It shows promise to become a novel drug candidate for the treatment of gastrointestinal motility disorders (GMDs). However, the pharmacokinetic behavior of (S)-MP3950 in the pathological state of GMDs remains unclear. Herein, we investigated the comparative pharmacokinetics of (S)-MP3950 in normal and GMDs rats. 2. The comparative pharmacokinetics of (S)-MP3950 in normal and atropine-induced GMD rats were studied by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The validated UPLC-MS/MS method was successfully applied to investigate the pharmacokinetic profiles of (S)-MP3950 in normal and atropine-induced GMDs rats. Results showed that comparing to normal rats, Cmax reduced by 73.8%, AUC0-t decreased by 57.6% and AUC0-∞ declined by 56.8% in model rats. Additionally, the elimination half-life (t1/2) and Tmax were prolonged slightly. 3. The pharmacokinetic results demonstrated that the atropine-induced GMDs reduced the absorption of (S)-MP3950. The pharmacokinetics research in the pathological state might provide more useful information for further study of novel gastric motility candidates.

Abstract
Pugionium cornutum (L.) Gaertn. (PCG) is a desert plant with edible and medicinal value. The contents of proximate composition, amino acids and vitamins of fresh and pickled PCG were analyzed. PCG is rich in dietary fiber, protein and vitamins. PCG is a dietary source of potassium and calcium, with low levels of fat and sugar. PCG contains all the 18 hydrolyzed amino acids. Pickled PCG protein is a high quality protein. A large quantity of vitamins are lost during the pickling process. The type and number of mice dejections, gastric emptying and intestinal propulsion were investigated using the water extract of fresh and pickled PCG (WEFP and WEPP) to determine their gastrointestinal prokinetic efficacy. The low-dose WEFP and WEPP promoted the gastrointestinal dynamics and the WEFP and WEPP promoted gastrointestinal activity and act as nonviolent drugs. The results indicate that PCG has great potential as a new functional food source.

Abstract
Background: Metoclopromide have local anesthetic properties. The main object of performing the present study was to evaluate the analgesic effect of metoclopromide 10 mg when added to lidocaine for intravenous regional anesthesia (IVRA) of upper extremities in trauma patients. Materials and Methods: Ninety patients undergoing upper limb producer were randomly allocated to the three groups to receive 3 mg/kg 2% lidocaine diluted with saline to a total dose of 40 ml (Group L, n = 30) or 10 mg metoclopromide plus 3 mg/kg 2% lidocaine diluted with saline to a total dose of 40 ml (group LM, n = 30) or 3 mg/kg 2% lidocaine diluted with saline to a total dose of 40 ml plus 10 mg metoclopromide intravenously (Group IM, n = 30). Results: Our study showed that the onset times for sensory and motor block were significantly shorter in Group LM compared with Group L and Group IM (4.5 ± 0.7 vs. 5.0 ± 0.7 and 5.0 ± 0.6, respectively, P = 0.006 for sensory block; 6.3 ± 0.7 vs. 5.1 ± 0.9 and 5.9 ± 0.6 respectively, P = 0.000 for motor block). The postoperative VAS scores were significantly less at 1, 5, 10, 15, and 30 minutes after tourniquet release in Group LM compared with Group L and Group IM (P < 0.05). Conclusion: The results of our study showed that adding 10 mg metoclopromide to lidocaine for IVRG in trauma patients reduced intraoperative and postoperative analgesic use till 24 hours and improve quality of anesthesia.

Preemptive treatment of nausea and vomiting of pregnancy: results of a randomized controlled trial. Obstet Gynecol Int 2013; 2013:809787.

Abstract
Objectives. To determine whether the initiation of treatment (preemptive treatment) before the symptoms of nausea and vomiting of pregnancy (NVP) versus when the symptoms begin can improve the outcome in patients at a high risk for recurrence of severe NVP. Study Design. Prospective, randomized controlled trial. Results. Preemptive therapy conferred a significant reduction in HG as compared to the previous pregnancy (P = 0.047). In the preemptive arm, there were 2.5-fold fewer cases of moderate-severe cases of NVP than those in the control group (15.4% versus 39.13%) in the first 3 weeks of NVP (P = 0.05). In the preemptive group, significantly more women had their NVP resolved before giving birth (78.2% versus 50%) (P < 0.002). Conclusions. Preemptive treatment with antiemetics is superior to the treatment that starts only when the symptoms have already occurred in decreasing the risk of severe forms of NVP.

Abstract
Through the years, patients have asked their physicians why they needed nasogastric inbutation (NGI), a painful test. Some recent studies have also questioned the utility of NGI for several indications, enabling physicians to use judgment in offering it to patients. This article reviews the use of NGI for its traditional indications: gastrointestinal bleeding, presenting with or without hematemesis; gastric decompression; and the administration of treatment. It concludes with suggestions for limiting the pain of the procedure for patients who need it.
