ive] To observe the effects of Shengjiang Capsule (SC) on gastric evacuation and to study its mechanism. [Methods] Eight-week-old SD rats were randomly allocated to five groups. Group A served as normal control, and Group B were treated with high dosage of SC, Group C with low dosage of SC, Group D with Zhike Baizhu Decotion and Group E with cisapride. After ten days of treatment, gas tric evacuation of rats was detected by isotope tracing method, erythrocyte-acetycholinesterase activity by micro-hydroxylamine method and plasma motilin (Mot) and somatostatin (SS) levels by radioimmunoas-say. [Results] Thirty-minute gastric evacuation rate was (51.44?.38)%, (40.82 + 7.24)% and (40.22?.16)% in Group B, Group C and Group D respectively, which was higher than that in Group A [ (33.18?.32)%]. Erythrocyte-acetycholinesterase activity, Mot and SS levels were (0.856?.128) umol/h, (124.26?5.94) ng/L and (39.42?.96) ng/L, and (0.726?.164 ) umol/h, (119.86 ?9.38) ng/L and (38.33 ?.64) ng/L in Group B and Group C respectively, which were higher than those in Group A [ (0.576 ?.150)/umol/h, (91.28 + 26.84) ng/L and (28.22 ?7.68)ng/L]. [Conclusion] SC can promote gastric evacuation, and its mechanism may be re lated to the increase of the cholinergic nerve function and plasma Mot and SS levels.

Objective:To compare the incidence of complications associated with arm and chest ports by Meta-analysis.Methods:To Janurary 2019, studies published in PubMed, Embase, CINAHL, Cochrane, CBM and Wanfang regarding complication comparison between arm ports and chest ports were searched. Newcastle-Ottawa Scale was applied to evaluate the quality of studies. Review Manager 5.3 software was applied to conduct this meta-analysis.Results:A total of 19 articles covering 4 203 patients were included. The results showed that the incidence of pneumothorax ( OR value was 0.22, 95% CI0.05-0.88, P value was 0.03) and artery injury ( OR value was 0.24, 95% CI0.07-0.77, P value was 0.02) between arm ports group and chest ports group were statistically significant. No significant difference was observed in infection ( OR value was 0.81, 95% CI0.58-1.12, P value was 0.20), thrombosis ( OR value was 1.25, 95% CI0.64-2.45, P value was 0.52), extravasation ( OR value was 1.13, 95% CI0.54-2.35, P value was 0.75), catheter misplacement ( OR value was 1.58, 95% CI0.95-2.61, P value was 0.08), skin incision ( OR value was 0.64, 95% CI0.23-1.74, P value was 0.38), sepsis ( OR value was 0.68, 95% CI0.27-1.70, P value was 0.41) and exudate ( OR value was 0.88, 95% CI0.32-2.42, P value was 0.80). Conclusion:The incidence of pneumothorax and artery injury in arm ports is significantly lower than in chest ports, there was no difference in other complications. More studies are needed to further confirm the advantages of arm ports.
