[Effects of Blood Activating Wind Dissipating Acupuncture on Blood Pressure of Prehypertension Patients].

OBJECTIVE: To observe the effects of blood activating wind dissipating acupuncture (BAWDA) on blood pressure (BP) of prehypertension (PHT) patients. METHODS: Totally 60 PHT patients were assigned to the control group and the acupuncture group according to random digit table, 30 in each group. All patients were intervened by life style. BAWDA was additionally performed in patients in the acupuncture group for 6 weeks (30 times). The improvement of BP after intervened by acupuncture was observed. BP success rates and the proportion of PHT progressing to hypertension (HT) were also observed after 6-week intervention of acupuncture and at 1-year follow-up. RESULTS: Systolic blood pressure (SBP) and diastolic blood pressure (DBP) decreased after 6-week intervention in the acupuncture. The BP control rate was 56.7% (17/30 cases) in the acupuncture group vs.10.0% (3/30 cases) in the control group with statistical difference (chi2 = 14.70, P < 0.01). At 1-year follow-up BP success rate was 36.7% (11/30 cases) in the acupuncture group, remarkably higher than that of the control group [13.3%, (4/30 cases)] (chi2 = 4.36, P < 0.05). CONCLUSIONS: BAWDA showed BP regulating roles in a gradually stable decreasing tendency. It also could elevate BP success rate of PHT, and reduce the risk of PHT progressing to HT.

The effect of procyanidin on expression of STAT1 in type 2 diabetes mellitus SD rats with focal cerebral ischemia.

OBJECTIVES: Diabetes with cerebral infarction is a common disease that severely impacts health. This study investigated the effect of procyanidin (PC) on the expression of signal transducers and activators of transcription (STAT1) in type 2 diabetes mellitus SD rats with focal cerebral ischemia. We then explored the protective mechanisms of PC in type 2 diabetes mellitus SD rats with focal cerebral ischemia, to provide theory evidence for its clinical application. METHODS: We set up a type 2 diabetes mellitus-MCAO model, evaluated neurological function, and used immunohistochemistry methods to measure the activity of STAT1. RESULTS: The brain expression of STAT1 in rats of the sham-operation group was low, but more STAT1 positive cells were found in normal rats with ischemia and in rats with both type 2 diabetes and ischemia when groups were compared with the sham-operation group (p<0.01). Compared with rats that had type 2 diabetes and ischemia, the numbers of STAT1 positive cells after low, medium and high-doses of PC were all decreased (p<0.01), whereby the mid and high-dose groups showed a more substantial decrease (p<0.01) and with no variance between the two groups (p>0.05). CONCLUSIONS: These results indicate that PC has a neuroprotective effect on type 2 diabetes mellitus-MCAO; this may be through decreasing the expression of STAT1, which influences the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway that may inhibit apoptosis to relieve neurological impairment.
