Objective To study the TCM syndrome distribution and the laws of blood pressure variability in patients with primary hypertension.Methods Totally 443 patients with primary hypertension were selected; four diagnostic data were collected to conduct syndrome differentiation (main syndrome was chosen for compound syndrome); 24 h ambulatory blood pressure was monitored and blood pressure variability of each syndrome was compared.Results Among 443 cases of patients, liver-kidney yin deficiency syndrome (157 cases) > qi yin deficiency syndrome (83 cases) > yang deficiency syndrome (76 cases) > phlegm dampness syndrome (65 cases) > liver yang hyperactivity syndrome (62 cases). There was statistical significance in ages of different syndromes, but there was no statistical significance in gender, family history and course of disease (P>0.05). Compared with liver-kidney yin deficiency syndrome, 24 h systolic blood pressure and 24 h mean blood pressure of phlegm dampness syndrome were significantly different (P<0.05); circadian rhythm abnormality rates of liver-kidney yin deficiency syndrome, liver yang hyperactivity syndrome, qi yin deficiency syndrome, phlegm dampness syndrome and yang deficiency syndrome were 80.85% (38/47), 66.67% (14/21) ,81.48% (22/27), 86.96% (20/23), and 78.79% (26/33), respectively, without statistical significance in different syndromes (χ2=3.031,P=0.553).Conclusion Among the 443 hypertensive patients, patients with liver-kidney yin deficiency syndrome were the most, and patients with liveryang hyperactivity syndrome were the least. Phlegm dampness syndrome has the highest blood pressure, while liveryang hyperactivity syndrome has the lowest blood pressure. Patients with liver-kidney yin deficiency syndrome are with the highest blood pressure variability, while patients with qi yin deficiency syndrome are with the lowest blood pressure variability.

Objective: To investigate the inlfuence of different blood pressure (BP) circadian rhythm on cardiac function in hypertensive patients.
Methods: A total of 180 hypertensive patients with well controlled day-time blood pressure were divided into 3 groups. Dipper group, n=30, Non-dipper group, n=99 and Reverse dipper group, n=51. The relationship between cardiac function, relevant clinical index and blood pressure circadian rhythm were analyzed.
Results: The mean systolic and diastolic BP, BP classiifcation and the antihypertensive medication were similar among 3 groups.①The ratio of peak mitral E wave to peak mitral annulus E' wave (E/E') increased accordingly from Dipper group, Non-dipper group and Reverse-dipper group as (8.1 ± 2.4), (8.6 ± 2.5) and (9.6 ± 3.2), P<0.05. ②Left atrial volume index (LAVi) in Reverse-dipper and Non-dipper groups were higher than that in Dipper group as (43.8 ± 11.8) ml/m2, (40.7 ± 9.8) ml/m2 and (36.6 ± 8.5) ml/m2, P<0.05 or P<0.01. ③E/E' was positively related to nocturnal systolic BP and age, negatively related to nocturnal BP decline rate (nocturnal BPR); E/E' was independently related to age and BPR. LAVi was positively related to nocturnal systolic BP, pulse pressure, age and hypertension course, negatively related to the mean diastolic BP, day-time diastolic BP and BPR; LAVi was independently related to BPR, pulse pressure and hypertension course. Left ventricular ejection fraction had no statistic differences among 3 groups.
Conclusion: Abnormal blood pressure circadian rhythm was associated with the cardiac injury in hypertensive patients. The cardiac injury increased accordingly from Non-dipper group to Reverse-dipper group and the main damage was in diastolic function.
