Objective To investigate the role of WNK4 gene Exon8 Ala589Ser polymorphism in the pathogenesis of essential hypertension. Methods This study included 259 hypertensive patients and 235 normotensive patients as control subjects. Exon8 Ala589Ser polymorphism in WNK4 was investigated by PCR-RFLP and confirmed by direct sequencing. Genotype, genotype frequencies and allele frequencies of the polymorphism were compared among patients with essential hypertension and control subjects. At the same time, some clinical biochemical variables, such as the blood sugar and lipids in both groups. All of these results were analyzed with Logistic regression analysis to determine whether the risk of hypertension is associated with the polymorphism and the determined biochemical variables. Results The allele frequency of Exon8 Ala589Ser polymorphism in WNK4 in hypertensive patients was significantly higher (P

9.Clinical observation on acupuncture at points of Shaoyang meridians plus moving cupping on the neck and shoulder for migraine
Journal of Acupuncture and Tuina Science 2017;15(5):377-381
Objective:To observe the efficacy of acupuncture at points of Shaoyang meridians plus moving cupping on neck and shoulder for migraine. Methods:A total of 64 migraine cases were randomly allocated into an observation group and a control group, 32 cases in each group. Random number table method was used in allocation. Acupuncture at points of Shaoyang meridians and cupping on neck and shoulder were used for cases in the observation group, which contain acupuncture 5 times a week and cupping once a week. Oral flunarizine hydrochloride capsules were used for cases in the control group, 10 mg for each dose, 1 dose a day. 2 weeks constitutes a course of treatment. The patients were treated for two courses of treatment in both groups. After that, the changes of visual analogue scale (VAS) and the migraine disability assessment questionnaire (MIDAS) were observed, as well as the clinical efficacy. Results:The total effective rate and recovery and marked effective rate in the observation group were 93.8% and 71.0% respectively, versus 78.1% and 43.8% in the control group, showing statistical significant differences (both P<0.05). There were significant decreases in VAS and MIDAS scores after treatments in both groups (both P<0.05). VAS and MIDAS scores in the observation group were significantly different from those in the control group (both P<0.05). Conclusion: Combining acupuncture at points of Shaoyang meridians and cupping on neck and shoulder can relieve headache and reduce influence of migraine on life. It can produce a better efficacy than oral flunarizine hydrochloride capsules in treating migraine patients.
