目的观察中药四磨汤对胆道手术后患者肠功能恢复的影响。方法133例行胆道术患者分为治疗组(90例)和对照组(43例),治疗组患者术前2h和术后每6h口服四磨汤30—40ml,对照组患者术后采用常规治疗,观察记录两组患者肛门排气时间。结果治疗组患者术后肛门排气时间较对照组显著提前(P<0.001)。结论术前、术后口服四磨汤可有效促进胆道手术患者肠功能恢复。

Objective To analyze the spatial distribution patterns of rodent community and the risk factors of disease transmission in natural foci of Xiji County,Ningxia,in order to provide a scientific basis for disease control and prevention.Methods Rodents were captured at different habitats in different latitudes which were selected with a stratified sampling method in 2012-2013.Capture rate of different rodent species and spatial distribution patterns of the animal community were analyzed.Antigen and antibody of hantavirus were detected in lung tissue and blood of the rodents with immunofluorescence and enzyme-linked immunosorbent assay (ELISA),respectively.Serum F1 antibody of Yersinia pestis (Y.pestis) was detected with indirect hemagglutination test and Y.pestis from liver and spleen tissue was cultured in vitro.Results Fourteen species of rodents were captured,belonging to 2 orders,7 families and 9 genera.Among them,ground squirrels and wood mouse were dominant species,accounted for 49.56％ (112/226) and 34.51％ (78/226) of the community,respectively.Infections of hantavirus and Y.pestis were not found in the rodent's community.Conclusion With the improvement of ecological environment in Xiji County,the spatial distribution patterns of rodent community is changing; the risk of zoonotic plague is reduced,but the risk of hemorrhagic fever with renal syndrome is being.
