Abstract： Objective： To observe the clinical effect of modified Longdan Xiegan Tang combined with auricular point seed- pressing assisting routine western medicine for insomnia complicated with essential hypertension. Methods： A total of 62 cases of patients with insomnia complicated with essential hypertension were selected and divided into the observation group and the control group according to the random number table method，with 31 cases in each group. Both groups were given routine hypertension management；the control group was given Alprazolam orally before sleep，and the observation group was additionally treated with modified Longdan Xiegan Tang combined with auricular point seed-pressing based on the treatment of the control group. The clinical effects， 24- hour ambulatory blood pressure indexes， traditional Chinese medicine(TCM) syndrome scores， Pittsburgh Sleep Quality Index(PSQI) scores and scores of quality of life in the two groups were compared. The incidence of adverse reactions in the two groups were recorded. Results：The total effective rate was 93.55% in the observation group，higher than that of 74.19% in the control group，the difference being significant(P＜0.05). Before treatment，there was no significant difference being found in the comparison of mean 24-hour diastolic blood pressure(24 h DBP) and 24- hour systolic blood pressure(24 h SBP) between the two groups(P＞0.05). After treatment， the levels of 24- hour DBP and 24- hour SBP in the two groups were decreased when compared with those before treatment(P＜0.05)， and the decrease in the observation group was larger than that in the control group(P＜0.05). Before treatment， there was no significant difference being found in the comparison of scores of TCM syndromes，PSQI and quality of life between the two groups(P＞0.05). After treatment，the scores of TCM syndromes，PSQI and quality of life in the two groups were decreased when compared with those before treatment(P＜0.05)， and the scores in the observation group were lower than those in the control group(P＜0.05). There was no significant difference being found in the comparison of the incidence of adverse reactions between the two groups(P＞0.05). Conclusion： Modified Longdan Xiegan Tang combined with auricular point seed-pressing assisting routine western medicine has a good curative effect in treating insomnia complicated with essential hypertension， which can improve sleep quality， clinical symptoms and quality of life in patients.
