ABSTRACT
Objective To study the clinical efficacy and safety of Simo Decoction for the treatment of feeding intolerance of near term infants; To explore the value of increase of time averaged mean velocity (TAMV) in the superior mesenteric artery. Methods Totally 85 patients were randomly divided into control group (41 cases) and observation group (44 cases). Both two group were given comprehensive treatment and feeding regulation, lasted for 7 d. The observation group was given Simo Decoction on the basis of the control group, 1 mL/kg each time, 3 times a day, orally or nasal feeding, lasted for 2 days. After the treatment, no gastric retention time, vomiting ceased time, total enteral nutrition time, and hospitalization time were compared, and the total TCM syndrome scores and TAMV increase were observed. Clinical efficacy was evaluated and safety indexes were monitored. Results No gastric retention time, vomiting ceased time, total enteral nutrition time and hospitalization time in the observation group were shorter than the control group (P<0.05). Compared with before treatment, the total TCM syndrome scores in the two groups decreased after treatment (P<0.05); After treatment, the total TCM syndrome scores in the observation group were lower than those in the control group (P<0.05). The total effective rate was 86.36% (38/44) in the observation group and 68.29% (28/41) in the control group. The observation group was significantly better than the control group (P<0.05); After treatment, the TAMV increase in the observation group was higher than that in the control group (P<0.05). No adverse reactions occurred in both groups. Conclusion Simo Decoction can improve the symptoms and shorten the time of hospitalization in the treatment of feeding intolerance of near term infants, with confirmed efficacy and no obvious adverse reactions, which can be prejudged and monitored by monitoring TAMV increase.
ABSTRACT
Objective · To investigate the effects of simo decoction combined with mannitol on the intestinal preparation of magnetically guided capsule endoscopy (MGCE). Methods · A total of 120 patients were enrolled in this randomized controlled trial and randomly divided into two groups according to the random number table. The observation group (n=60) was pretreated with simo decoction 20 mL each time, 3 times a day combined with mannitol 500 mL for oral administration before MGCE examination, while control group (n=60) only was done with mannitol 500 mL for oral administration. Then the intestinal cleanliness and occurrence of adverse reaction were observed.

ABSTRACT
Objective To investigate the effect of Simo decoction oral liquid on inflammatory in acute respiratory distress syndrome (ARDS) mouse serum and the bronchoalveolar lavage fluid (BALF) and to explore the mechanism.Methods Fifty BALB/c mice were divided into normal control group, ARDS model group, small, moderate and large dose Simo decoction oral liquid-treated groups (simplified as Simo groups) according to random number table method (n=10, in each group). The ARDS model mice were replicated by lipopolysaccharide (LPS) tracheal instillation, and the mice in normal control group were given the same amount of normal saline. Immediately after the success of modeling, the mice were gavaged with 1, 2, 4 times the equivalent dose Simo decoction oral liquid of 7.56 mL·kg-1·d-1 in small, moderate or large dose Simo groups respectively, and there was no intervention in the normal control group or ARDS model group. All the mice were sacrificed at 24 hours after the respective drug amount or normal saline was given in various groups. The lung samples were taken for histologic evaluation, and BALF and serum samples were analyzed for the tumor necrosis factor-α(TNF-α), interleukin (IL-1β, IL-6), and in the mean time the level of serum superoxide dismutase (SOD) was detected.Results The pathological observation of lung tissue showed: there was no obvious inflammatory exudation in lung tissue of mice in normal control group; the inflammatory exudation in lung tissue of mice was increased significantly, the level of TNF-α (ng/L: 1759±303 vs. 104±27, 2506±674 vs. 507±46), IL-1β(ng/L: 209±16 vs. 114±11, 7325±826 vs. 3513±498) and IL-6 (ng/L: 144±38 vs. 47±7, 126±38 vs. 15±7) in serum and BALF were significantly increased, and the content of SOD (kU/L: 40.26±2.54 vs. 50.68±3.75) in serum was significantly decreased in ARDS model group (allP < 0.05), indicating that animal model of ARDS was set up successfully. Compared with ARDS model group, in small, moderate and large dose Simo groups, the inflammation exudation in lung tissue of mouse was reduced, the levels of TNF-α, IL-1βand IL-6 in serum and BALF were reduced, and the content of SOD in serum was increased [serum: TNF-α(ng/L) was 1642±276, 1126±154, 817±102 vs. 1759±303, IL-1β(ng/L)was 198±12, 170±11, 141±13 vs. 209±16, IL-6 (ng/L) was 127±22, 82±16, 41±15 vs. 144±38, SOD (kU/L) was 42.11±1.64, 48.09±1.23 vs. 40.26±2.54; BALF: TNF-α(ng/L) was 2479±446, 1632±330, 1067±223 vs. 2506±674, IL-1β(ng/L): 6939±725, 5398±625, 4401±210 vs. 7325±826, IL-6 (ng/L): 106±30, 68±13, 34±10 vs. 126±38, allP < 0.05], showing the Simo decoction inhibiting the lung inflammation and the above levels of indexes inserum and BALF was in a dose-dependent manner, and the changes in large dose Simo group was the most significant 45.18±1.15, .Conclusions Simo decoction oral liquid can inhibit the inflammatory response of ARDS, reduce the oxidative stress and decrease the lung injury of mice with ARDS.
ABSTRACT
Background:Gastrointestinal dysmotility is frequently seen in patients with chronic obstructive pulmonary disease ( COPD). Simo Decoction is used for promoting gastrointestinal motility in clinical practice. Aims:To study the effect of Simo Decoction on gastrointestinal symptoms and motility in patients with COPD. Methods:Thirty-six patients with stable COPD in Shiyan Renmin Hospital from Sep. 2012 to Jun. 2013 were enrolled and received a 28-day course treatment of Simo Decoction oral solution,19 healthy volunteers were served as controls. All subjects were assessed with gastrointestinal symptom rating scale(GSRS). Electrogastrography was performed and levels of vasoactive intestinal peptide(VIP)and intestinal fatty acid-binding protein( I-FABP)in peripheral blood were measured. Patients with COPD were re-examined for the above-mentioned parameters after treated with Simo Decoction. Results:The baseline GSRS score and serum I-FABP level in COPD patients were significantly increased as compared with controls(P<0. 05),while the baseline serum VIP level,as well as the fasting and postprandial normal gastric slow wave percentage in COPD patients were significantly decreased(P <0. 05). After 28-day course of Simo Decoction treatment,all these parameters in COPD patients were improved as compared with those before treatment(P<0. 05),serum levels of VIP,I-FABP and normal gastric slow wave percentage were similar to those of controls. Conclusions:Simo Decoction can ameliorate the gastrointestinal symptoms and dysmotility in patients with COPD. The regulatory effect of Simo Decoction on gastrointestinal motility might be bidirectional.
ABSTRACT
Objective To discuss the efficacy and pharmacological mechanism of Simo decoction to assist the treatment of postoperative gastrointestinal dysfunction. Methods 200 mice (100 male and 100 female) were randomly divided into four groups (n=50). The mice of blank group were feed as normal,and the mice in the other three groups were prepared for colon postoperative gastrointestinal dysfunction model. Then,trimebutine maleate group were given trimebutine maleate while the combined group were given trimebutine maleate and simo decoction through gavage,and model group and blank group were given the same doses of distilled water. One week later,the abdominal ve-nous blood of mice was extracted and serum levels of acetylcholine ( ACH) and norepinephrine ( NE) were detected using ELISA kit. At the samd time,the gastric emptying and intestinal propulsion experiment was carried on. Results After modeling,compared with blank group, MUPA of the rest three groups were significantly decreased (P0. 05). After drug intervention,MUPA of trimebutine maleate group was significantly higher than that of model group,and MUPA of combined group was significantly higher than that of trimebutine maleate group (P<0. 05). In addition,compared with blank group,the gas-tric emptying rate,intestinal propulsion rate,serum ACH concentration and NE concentration of the rest three groups were significantly lower (P<0. 05). Compared with model group,each index of both trimebutine maleate group and combined group was increased,and combined group increased higher (P<0. 05). Conclusion Simo decoction combined trimebutine maleate has high effect to improve the level of ACH and NE of postoperative gastrointestinal dysfunction mice,which benefit to promote gastrointestinal peristalsis and may be one of its pharmaco-logical mechanisms.
ABSTRACT
Objective To investigate the effects of Simo decoction on ghrelin and calcitonin gene-related peptide (CGRP) in diabetic rats.Methods A total of 48 SD rats were divided into healthy control group,diabetes group (DM),DM treated with low dose Simo decoction group (DMTL),DM treated with medium dose Simo decoction group (DM-TM),DM treated with high dose Simo decoction group (DM-TH) and DM prevented with medium dose Simo decoction group (DMPM) ; there were eight rats in each group.The rats of DM group and other intervention groups were intraperitoneally injected with 1％ streptozotoein (STZ) to establish the model.The rats of healthy control group were injected with solvent.At eight weeks after the model successfully established,the rats of each intervention group were gavaged with low dose of Simo decoction (0.15 ml · kg-1 · d-1 ),medium dose of Simo decoction (1.5 ml · kg-1 · d-1 ) and high dose of Simo decoction (3.0 ml · kg-1 ·d-1 ) for two weeks; the rats of control group and DM groups were gavaged with equal volume of 0.9％NaCl.The rats of DM-PM group were gavaged with Simo decoction at 1.5 ml · kg-1 · d-1 for 10 weeks after the model successfully established.Rats were sacrificed at the end of drug intervention and gastric antrum tissues were dissociated for detecting the expression of ghrelin and CGRP by real time polymerase chain reaction (PCR).The data were analyzed by one way ANOVA and t test.Results There was no significant difference in ghrelin expression at mRNA level in gastric antrum tissues between diabetic rats and control group.However after intervened by low dose and medium dose of Simo decoction,the ghrelin expression increased (1.45 ± 0.34,1.87 ± 0.68 compared with 0.87 ±0.28,Dunnett's T3 test,P＜0.05).There was no effects of high dose Simo decoction on the expression of ghrelin in diabetic rats.There was no significant difference in ghrelin between DM-TM and DM-PM.The expression of CGRP at mRNA level in gastric antrum tissues of diabetic rats was significantly higher than that of control group (4.61 ± 1.67 compared with 1.06 ± 0.40,t =5.843,P＜0.01).There was no effects of low dose Simo decoction on CGRP expression of diabetic rats.The expression of CGRP of diabetic rats was down-regulated by medium and high dose of Simo decoction intervention.There was no significant difference in CGRP expression between DM-TM and DM-PM.Conclusions Simo decoction can promote ghrelin expression in gastric antrum of diabetic rats.The expression of CGRP in gastric antrum of diabetic rats significantly increased,but Simo decoction may down-regulate the expression of CGRP in gastric antrum of diabetic rats.
