OBJECTIVE: To explore the clinical effect of Pinggan Jiangya decoction combined with penetrating needling at Baihui (GV20) in a period of day from 7 am to 9 am in the treatment of grade 1 and 2 essential hypertension (EH). METHODS: A total of 150 cases of grade 1 and 2 EH patients were randomized into an observation group and a control group, 75 cases in each group. In the control group, Pinggan Jiangya decoction was prescribed for oral administration one dose a day, while in the observation group, on the basis of the treatment as the control group, penetrating needling was exerted at GV20 once daily. The treatment duration was 8 weeks. Before and after treatment, the TCM syndrome score, 24 h average systolic blood pressure (24 h ASBP), 24 h average diastolic blood pressure (24 h ADBP), 24 h average pulse pressure difference (24 h PP), morning blood pressure surge (MBPS), 24 h SBP variability (24 h SBPV), 24 h DBP variability (24 h DBPV), serum levels of 5-hydroxytryptamine (5-HT) and melatonin (MT) were compared in the patients of the two groups. The clinical therapeutic effect was observed in the two groups. RESULTS: After the treatment, in the self-comparison of each group, the scores of headache, vertigo, backache, soft knees, tinnitus, 24 h ASBP， 24 h ADBP, 24 h PP, MBPS, 24 h SBPV and 24 h DBPV in the two groups were lower than those before treatment (P<0.01), and the above indexes in the observation group were lower than those in the control group (P<0.01). The level of serum 5-HT after the treatment was lower than that of before the treatment (P<0.01), while the level of MT was higher than that of before the treatment (P<0.01) in both two groups, and the level of 5-HT in the observation group was lower than that of the control group, while the level of MT was higher than that of the control group (P<0.01). The total effective rate of the observation group was 93.3% (70/75), better than 76.0% (57/75) of the control group (P<0.01). CONCLUSION: Pinggan Jiangya decoction combined with penetrating needling at GV20 in a period of day from 7 am to 9 am can regulate the levels of serum MT and 5-HT, effectively reduce blood pressure, improve blood pressure variability, control morning peak blood pressure, and has a remarkable effect in the treatment of grade 1 and 2 EH.
