Effects of dexmedetomidine on plasma motilin and postoperative nausea and vomiting in patients undergoing gynecological laparoscopic surgery / 医学研究生学报

Objective Increased pneumoperitoneum and intra-abdominal pressure during laparoscopic surgery may cause postoperative nausea and vomiting (PONV), avoiding the occurrence of which can accelerate postoperative recovery of the patients. In this study, we observed the effects of dexmedetomidine (DEX) on plasma motilin (MTL) and PONV in patients undergoing gynecologic laparoscopic surgery. Methods Eighty female patients underwent gynecological laparoscopic surgery under elective general anesthesia in our hospital from June 2017 to June 2018. We randomly assigned the patients to a control and a DEX group of equal number, the former injected intravenously with isotonic saline for 10 minutes at 40 minutes before the completion of surgery and the latter with DEX 0.5 μg/kg at 40 minutes before the end of and DEX 2.5 μg/kg + sufentanil 2.5 μg/kg after surgery. We compared the cough and sedation agitation scores (SAS) of the patients before and after extubation, the MTL concentration before and at 2, 24 and 48 hours after surgery, and the incidence and severity of PONV at 2, 24 and 48 hours postoperatively between the two groups. Results Compared with the controls, the patients of the DEX group showed significantly decreased cough and SAS scores before and after extubation (P < 0.05), MTL concentration at 2 hours ([478.81 ± 42.94] vs [391.39 ± 54.49] pg/mL, P < 0.05) and 24 hours after surgery ([385.64 ± 38.03] vs [321.96 ± 36.50] pg/mL, P < 0.05), and incidence rate of severe PONV at 2 hours (25.0% vs 5.0%, P < 0.05) and 24 hours postoperatively (20.0% vs 2.5%, P < 0.05). Intravenous pump injection of DEX at 0.5 µg/kg before the end of surgery can inhibit the postoperative release of MTL, effectively reduce the incidence and severity of PONV, and contribute to early recovery of the patients undergoing gynecologic laparoscopic surgery. Conclusion In gynecological laparoscopic surgery,0.5 µg/kg DEX used before the end of the surgery and low-dose maintenance of PCIA can inhibit the release of MTL after operation, effectively reduce the incidence and severity of PONV and improve the recovery quality of patients during anesthesia recovery period at the same time.

Influences of Chinese herbal compound Qinghuayin on serum IL-10 ,NO , GAS and plasma MTL in animal model of chronic atrophic gastritis in rats / 西安交通大学学报(医学版)

Objective To explore the effects of Chinese herbal compound Qinghuayin on the pathological changes of gastric mucosa and interleukin-10 (IL-10) ,nitric oxide (NO) ,gasmn (GAS) and motilin (MTL) in the serum in the animal model of chronic atrophic gastritis (CAG ) in rats .Methods We divided 53 Wistar rats randomly into blank control group (n=8) and CAG model group (n=45) ,and the animal model of CAG in rats was replicated by combination of disease and syndrome .After confirming the sampled rat model was successful built , the other 40 CAG rats in CAG model group were divided into model group ,vitacoenzyme tablet group ,low-dosage TMC group ,medium-dosage TMC group ,and high-dosage TMC group (each group n=8) .With the corresponding drug intervention to different rats for 30 days , the rats were executed . Then their blood was drawn from the abdominal aorta and the gastric tissue was taken to analyze the changes of serum IL-10 ,NO ,GAS and MTL concentrations and gastric mucosa pathology . Results Compared with blank control group , model group had various degrees of gastric mucosa atrophy ; decreased concentrations of serum IL-10 and GAS ; increased NO and MTL ( P<0 .01 ) .Compared with model group,Qinghuayin could improve gastric mucosa pathology in different degrees and increase the concentrations of IL-10 and GAS . Decrease the concentrations of NO and MTL( P<0 .05 or P<0 .01 ) . What's more. The curative effect in high-dosage TMC group was better( P<0. 01 ). Conclusion Chinese herbal compound Qinghuayin can effectively regulate the lopsided expressions of serum IL-10 . NO .GAS and MTL and reverse the pathological and histological changes in the gastric mucosa of CAG rats .

Dalitong granule combined with electroacupuncture in the treatment of functional dyspepsia: A randomized controlled trial / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore clinical short and long-term effect of combining dalitong granule (DG) and electroacupuncture group (EA) in the treatment of functional dyspepsia.</p><p><b>METHODS</b>Totally 640 patients with confirmed functional dyspepsia were randomly divided into 4 groups using a randomized digital table: the DG group, the EA group, the combined group and the control group, 160 cases in each group. The DG group was treated with 6 g DG 3 times daily; the EA group was treated with puncture of points Zusanli (ST36), Zhongwan (CV12), Neiguan (PC6), Taichong (LR3) and Gongsun (SP4) twice daily; the combined group with above-mentioned DG and EA; and the control group with 5 mg mosapride 3 times, 20 mg pantoprazole and 25 mg amitriptylines twice daily. The treatment course was 4 weeks for all groups. The symptom score, quality of life score by Short Form 36 Health Survey Questionnaires (SF-36), plasma motilin by radioimmunoassay, electrogastrographic frequencies by electrogastrogram (EGG) and gastric emptying by B-sonography were examined, and adverse reactions were observed before, at the end of treatment and 60 weeks post-treatment.</p><p><b>RESULTS</b>In the DG group 1 case dropped out for not taking medicine strictly and 1 case was lost to follow-up, while 1 case in the EA group and 2 cases in the combined therapy group were lost to follow-up. Compared with pre-treatment, quality of life score, plasma motilin, electrogastrographic frequencies and gastric emptying were all increased significantly, while symptom score was decreased significantly at the end of treatment in each group (P<0.01); in the combined group quality of life score, plasma motilin, electrogastrographic frequencies and gastric emptying were all significantly higher than those in the other groups, while symptom score was significantly lower than in the other groups (P<0.05). Compared with at the end of treatment, these indices changed insignificantly in the combined group and the EA group 60 weeks post-treatment (P>0.05), but the 4 increased indices were all decreased significantly, and symptom score was increased significantly in the DG and the control groups (P>0.05). The short and long-term total effective rates in the combined group were all significantly higher than those in the other treatment groups (P<0.05 or P<0.01). No serious adverse reaction occurred in the four groups.</p><p><b>CONCLUSION</b>Combined treatment of DG and EA could increase both plasma motilin and electrogastrographic frequencies, promote gastric emptying, alleviate the symptom of dyspepsia so as to increase quality of life, with better safety and long-term effect.</p>

Objective To investigate the influence of Zengshiling oral liquid on gastric emptying,plasma motilin (MOT) and small intestine propulsion of young rat. Methods Experiment animal were divided into five groups randomly:control group,large dose of Zengshiling oral liquid group,normal dose of Zengshiling oral liquid group,small dose of Zengshiling oral liquid group and Motilium group. The rats were gavaged by 0.9% of NaCl and corresponding drug. 7 days later,gastric emptying was assayed by phenol red,plasma MOT levels and carbon powder propelling rate of small intestine were also assayed. Results The rate of gastric emptying of Zengshiling oral liquid groups were significantly higher than control group (P
