RESUMO
Objective: To observe the clinical efficacy of pushing Qiaogong point with varying intensities for treating stage Ⅰ essential hypertension. Methods: A total of 72 patients diagnosed with stageⅠ essential hypertension were enrolled in this study. They were divided into three groups using the random number table method, including a control group, a gentle pushing group, and a heavy pushing group, with 24 patients in each group. All three groups received the same therapeutic lifestyle interventions. The control group received no additional interventions, the gentle pushing group received additional pushing Qiaogong point with gentle strength, and the heavy pushing group received additional pushing Qiaogong point with heavy strength. The treatment duration was 4 weeks, followed by a 4-week follow-up period, during which blood pressure changes were observed and analyzed in all three groups. Results: After treatment, the blood pressure levels in all three groups showed a significant decrease (P<0.05). The effective rate in the control group was 43.5％, in the gentle pushing group was 78.3％, and in the heavy pushing group was 33.3％. The reduction in blood pressure levels in the gentle pushing group was significantly superior to that in both the control group and the heavy pushing group, indicating inter-group statistical significance (P<0.01). The efficacy of the heavy pushing group was comparable to that of the control group, indicating no statistical significance (P>0.05). During the follow-up period, compared with the end of the treatment within the same group, the blood pressure levels remained stable in both the control group and the gentle pushing group, indicating no intra-group statistical significance (P>0.05). The heavy pushing group showed a significant decrease in diastolic blood pressure (DBP) and mean blood pressure (MBP) compared with the end of the treatment, indicating intra-group statistical significance (P<0.05). During the follow-up, the gentle pushing group had lower systolic blood pressure (SBP) and MBP compared with both the heavy pushing group and the control group, indicating inter-group statistical significance (P<0.01), while there was no inter-group statistical significance in comparing the DBP (P>0.05). There was no statistical significance in comparing the SBP, DBP, and MBP between the heavy pushing group and the control group (P>0.05). Conclusion: Pushing Qiaogong point with gentle strength combined with lifestyle interventions showed a higher effective rate and long-term blood pressure stability in the treatment of stage Ⅰ essential hypertension. Pushing Qiaogong point with varying intensities showed varying effects on patients with stage Ⅰ essential hypertension.
RESUMO
Objective To apply joint fixation with breast bracket and body phantom to breast cancer radiotherapy after breast-conserving operation.Methods Totally 36 patients after breast-conserving operation underwent joint fixation with breast bracket and body phantom, whose cone beam computed tomography (CBCT) images were obtained with on board imager (OBI) before radiotherapy. The errors between the CBCT images and planning CT images were acquired by matching.Results The setup errors in the directions of left-right (X), head-foot (Y) and belly-back (Z) were (2.6±0.783), (3.0± 1.027) and (1.6 ±0.872)mm respectively, and the percentages that the setup errors were more than 5 mm were 16.5%, 20.7% and 9.1% respectively.Conclusion Joint fixation with breast bracket and body phantom may decrease the setup error in radiotherapy after breast-conserving operation, especially in the belly-back direction, and thus has high clinical values.
