Objective To investigate the effects of different degrees and duration of hypothermia on severe traumatic brain injury in dogs. Methods Thirty-six one-year-old healthy dogs weighing 13-15 kg were used in this study. Traumatic brain injury model was estabhshed according to the method described by Feeney. Orthogonal design was used in this experiment. Two empirical factors: temperature (factor A) and duration (factor B) were used. Body temperature was maintained at 38 ℃ (A1), 31 ℃ (A2) or35 ℃ (A3) for 6 h (B1) or 12 h (B2).The dogs were divided into 6 groups: group A1B1 , A1B2, A2B1, A2B2, A3B1 and A3B2. Blood gas analysis was performed after the target temperature was maintained for the target duration. Neurological deficit was assessed and scored (0 = no deficit, 500 = severe neurological deficit) and blood samples were obtained at 24, 48 and 72 h after brain injury for determination of serum concentrations of neuron-specific enolase (NSE) and myelin basic protein (MBP) and plasma S-100β protein concentration. Brains were removed at the 72 h after brain injury for determination of Bcl-2 and Bax expression and detection of apoptosis in the brain. Results Hypothermia significantly decreased serum NSE, MBP and plasma S-100β concentrations, neuronal apoptosis and NDS scores;up-regulated Bcl-2 expression and down-regulated Bax expression in brain tissue in the 4 hypothermia groups (group A2B1, A2B2, A3B1 and A3B2) as compared with the control groups (group A1 B1, A1 B2). Best neuroprotective effects were observed in group A3 B1 (35 ℃ for 6 h) in terms of serum NSE, NBP and plasma S-100β concentrations, neuronal apoptosis and cerebral Bax and Bcl-2 expression, but there was no significant difference in the NDS scores among the 4 hypothermia groups. Conclusion Hypothermia can provide neuroprotection in a dog model of traumatic brain injury but the neuroprotective effect is independent of the degree and duration of hypothermia.

Objective To observe the efficacy of lowering blood pressures and TCM syndrome on the mild to moderate hypertension via the treatment of auricular syndrome differentiation combined with magnetic point application;To provide reference for clinical treatment of hypertension by non-pharmaceutical therapy. Methods Totally 260 patients with mild to moderate hypertension were randomly divided into control group and treatment group, 130 cases for each. The control group was given Norvasc by conventional oral dosage, and the treatment group was given auricular syndrome differentiation and Yongquan (KI1) magnetic point application additionally. SBP, DBP and TCM syndrome scores of the two groups were observed before and after treatment to evaluate the antihypertensive efficacy and TCM syndrome efficacy. The side effects were also observed. Results After treatment, SBP of the two groups decreased significantly (P<0.05), with no significant difference (P>0.05). DBP of the treatment group decreased significantly (P<0.05), with significant difference compared with the control group (P<0.05). There was no significant difference in antihypertensive efficacy between the two groups (P>0.05). TCM syndrome of treatment group improved significantly compared with the control group (P<0.05). The total effective rate of TCM syndromes in treatment group was better than the control group (P<0.05), without side effects. Conclusion Auricular syndrome differentiation combined with magnetic point application can not only significantly improve the TCM syndrome of patients with mild to moderate hypertension, but also has synergistic hypotensive efficacy and high safety.
