Background
Induction of labor is a common obstetric procedure. Acupressure is a natural method that is used for inducing uterine contractions. Nevertheless, few studies have examined the impact of acupressure on the induction of labor.Aim
The aim of this study was to evaluate the effect of acupressure on the initiation of labor.Material and methods
In this randomized clinical trial, 162 nulliparous pregnant women were admitted to the hospital. They were categorized into 3 groups; acupressure, sham acupressure and control. Acupressure points SP6, BL 60 and BL 32 were pressured bilaterally. The intervention was done by the researcher every other day between 9 am and 11 am. The intervention was carried out on women in the afternoon and the following day. Subjects were examined to determine the initiation of labor symptoms48 and 96 h after the start of intervention and at the time of hospitalization. Data were analyzed using the ANOVA, Kruskal–Wallis and Chi-square tests (p < 0.05).Results
There was no significant difference among the groups for spontaneous initiation of labor within 48 h (P = 0.464), and 49–96 h after beginning the intervention (P = 0.111) and 97 h after beginning the intervention to the time of hospitalization for the spontaneous initiation of labor (P = 0.897). There were no significant differences in the secondary outcomes between the groups.Conclusion
According to the finding of this study, it seems that acupressure treatment was not effective in initiating labor as compared with the sham acupressure and the routine care groups. 相似文献2.

There has been an increasing interest in the evolution of urban forests. This research uses historic and digital aerial photography
to quantify changes in tree density in Los Angeles, California since the 1920’s. High-resolution geographic information system
analysis (4 to 6 time periods) of three regions (San Fernando Valley, Hollywood, Los Angeles Basin) of Los Angeles reveals
that there has not always been an increase in tree density with time. Tree densities on public and private land were highest
in the 1940’s in Hollywood, while the San Fernando Valley and Los Angeles Basin experienced a near linear increase in tree
density on both private and public land since the 1920’s. When historic tree density reconstructions were examined for the
15 Los Angeles city council districts from the 1920’s, 1950’s and 2006, most districts in Los Angeles have experienced a significant
increase in tree density, however, there has been wide variation in tree densities among city council districts. Trees densities
have generally been higher on private land since the 1920’s and currently tree densities on private land are significantly
higher than on public land. Results suggest the evolution of urban forests in Los Angeles mirrors the dynamics of urban forests
in desert and grassland cities. It is possible to reconstruct the development of urban forests in sections of cities using
historic and contemporary aerial photography. We estimated that Los Angeles averages approximately 104 trees per hectare (82
private land, 22 public land) based on 2006 imagery at 0.3 m resolution, however, field validation suggests that we identified
only 73% of trees. Although there is still space to plant trees on public land, private land owners will need to be heavily
involved in order to achieve the goals of Los Angeles’ Million Tree Initiative. 相似文献
