Methods One hundred and twenty patients who received radical gastrectomy for gastric cancer were randomly divided into two groups.Patients in the control group received continuous gastrointestinal decompression to drain the gastric juices after radical gastrectomy,whereas patients in the treatment group received vacuum sealed drainage.The postoperative variables between the two groups were compared,including time of bowel sound reoccurrence,time of the first flatus,indwelling time of gastric tube,days of hospitalization,and complications,such as anastomotic leakage,intestinal obstruction,wound infection,pulmonary infection,fever, and pharyngitis.SPSS 13.0 was used to analyze the data. Results Significant differences in the following variables were observed in patients between the two groups:time of bowel sound reoccurrence,time of the first flatus,indwelling time of gastric tube,and length of hospitalization of the patients.The value of each of these variables was much smaller in the treatment group than in the control group(P<0.05).No significant difference was found in the incidence of anastomotic leakage,intestinal obstruction,and wound infection among patients between the two groups(P>0.05). However,a significant differences were observed in the incidence of pulmonary infection,fever,and pharyngitis among the patients between the two groups(P<0.05),with much lower incidence of the variables in the treatment group than in the control group. Conclusions Vacuum sealed drainage used in gastric cancer patients after radical gastrectomy can accelerate the recovery of gastrointestinal function and reduce postoperative complications.Moreover,it shortens the indwelling time of the gastric tube, thereby making the patients feel comfortable without the disturbance from the gastric tube.展开更多

A series of programs have been implemented by the Chinese government to restore degraded grasslands in this region, and major function-oriented zones(MFOZs) applied in 2014, have divided the region into three zones, i.e., the development prioritized, restricted, and prohibited zones, based on environmental carrying capacity, as well as the utilization intensity of grassland. This study identified various restoration approaches adopted in different MFOZs, and assessed the effects of the approaches in order to determine the most effective approaches. We collected 195 questionnaires from herders to analyze the effects of the various restoration approaches, and additional remote sensing and statistical data were also used for the analysis. Four distinct differences in the ecological and socioeconomic characteristics were found in three MFOZs.(1) Five technologies were applied in the study areas.(2) The grassland recovery rate was higher in development prioritized zones than in restricted and prohibited zones during 2000 and 2016, and especially high and very high coverage grasslands increased in the areas where crop-forage cultivation and grass seeding dominated in the prioritized zones.(3) The net income of households in the development prioritized zone was the best of all three zones.(4) The degree of awareness and willingness of herders to restore grassland was more positive in development prioritized zones than in restricted zones, where more herders adopted approaches with a combination of enclosure + deratization + crop-forage cultivation + warm shed. Based on these findings, it is recommended that decision-makers need to increase their efforts to narrow the gap of willingness and behavior between herders and other stakeholders, such as researchers and grassland administrators, in order to ensure grassland sustainability in the MFOZs. It is also beneficial to understand the effects of restoration on the ecological carrying capacities in different zones depending on the different development goals.展开更多
