We conducted a retrospective analysis of breast cancer subtypes, tumor-nodal-metastatic （TNM） staging, and histopathological grade to investigate the value of these parameters in the treatment strategies of invasive breast cancer.展开更多

Methods： A total of 174 patients with grade 1 essential hypertension were randomly assigned to 3 groups with a random number table after Chinese medicine（CM） syndrome differentiation： the photoelectric and musical treatment group（Group 1, with a self-developed multi-mode audio frequency pulse photoelectric therapeutic apparatus）, acupuncture group（Group 2）, and oral placebo group（Group 3）, 58 cases per group. The curative effect of each group was evaluated by the changes of blood pressure and CM syndrome integral before and after treatment. Results： Compared with Group 3, there were significant decrease of blood pressure and CM syndrome integral in Group 1 and Group 2（P〈0.01）. Compared with Group 2, Group 1 showed the highest decrease in systolic pressure（P〈0.017）. The total effective rate of anti-hypertension in Group 1（91.38%, 53/58） was significantly higher than that in Group 2（74.13%, 43/58） and Group 3（18.97%, 11/58, P〈0.05 or P〈0.01）; and that in Group 2 was also significantly higher than that in Group 3（P〈0.01）. There were significant difference in the total effective rate of CM syndrome integral in both Group 1（93.10%, 54/58） and Group 2（84.48%, 49/58） as compared with Group 3（17.24%, 10/58, P〈0.01）, while there was no significant difference between Group 1 and Group 2（P〉0.05）. Conclusions： The multi-mode audio frequency pulse photoelectric therapeutic apparatus, combining music, laser and electric pulse stimulation, is clinically useful for grade 1 essential hypertension. This ＂three in one＂ therapy method is non-invasive, easy and simple to handle. It is expected to be popularized as a new alternative treatment.展开更多
