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.

objective To evaluate the clinical effect of touqing capsule associated with Fengchi on the vertebral artery type of cervical spondylosis(CSA)in the attack stage.Methods A total of 100 patients with CSA, according to the doctor order, were randomly divided into a control group and a treatment group respectively, with 50 patients in each. The control group was treated with acupuncture therapy, the treatment group was additionally treated with Touqingcapsule on the basis of the control group, and both groups were treated for 20 days. The hemodynamics was detected by transcranial doppler, the change of TCM syndrome integral was observed before and after the treatment, and the clinical efficacy was evaluated.Results After treatment, the treatment group dizziness (1.10 ± 0.33 vs. 2.01 ± 0.26,t=14.909), neck shoulder ache (0.87 ± 0.16 vs. 1.92 ± 0.69,t=10.266), numbness (0.95 ± 0.14)vs. 1.87 ± 0.16,t=29.844), the total integral (2.16 ± 0.75 vs.3.89 ± 1.14,t=8.756) integral were significantly lower than the control group(P<0.01).Treatment group RVA (40.03 ± 5.89 cm/svs. 34.26 ± 6.26 cm/s,t=4.628), the LVA (42.14 ± 5.42 cm/svs.33.89 ± 6.08 cm/s,t=6.985) rise and PI (0.79 ± 0.14 vs.1.04 ± 0.19,t=7.312) reduction were significantly better than those of the control group (P<0.01). The total effective rate in the treatment group was significantly better than the control group (91.7%(44/48)vs. 74.5%(35/47),χ2=3.863, P=3.863).Conclusion Touqing Capsule associated with Fengchi is effective for CSA. Its functional mechanism is correlated with improvement of haemodynamics of vertebral-basilar artery of the CSA patients.

Objective To investigate the effect of moderate static magnetic fields (SMF) on secretion of inflammato?ry factors tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6) and interleukin-8 (IL-8) in human monocytic leukemic cell line THP-1. Methods THP-1 cells at logarithmic phase were divided into control group and magnetic treatment group. CCK-8 method was used to detect cell proliferation after THP-1 cells were exposed to 60 mT, 200 mT and 400 mT static magnetic fields at 18, 24 and 48 h. Then THP-1 cells were divided into control group, magnetic treatment group, LPS activation group and LPS+SMF treatment group. When magnetic treatment group and LPS+SMF treatment group were ex?posed to SMF at 18, 24 and 48 h, the levels of the cytokines TNF-α, IL-6 and IL-8 were determined by ELISA. Results (1) 60 mT, 200 mT and 400 mT SMF had no significant effects on cell proliferation in THP-1 cells (P>0.05). (2)THP-1 cells secreted more TNF-αand IL-6 in 24 h than 18 h in every group, while IL-8 didn′t change. Compared with 24 h, the secre?tion of TNF-αdecreased and IL-6 didn′t change, while IL-8 increased in 48 h. At three sampled time THP-1 cells of LPS activation group secreted more TNF-α, IL-6, IL-8 than those of control group and magnetic treatment group. After magnetic treatment THP-1 cells of LPS+SMF treatment group secreted less TNF-α, IL-6, IL-8 than those of LPS activation group (P<0.05). Conclusion Static magnetic field may have some inhibitory effects on release of TNF-α, IL-6, IL-8 from THP-1 cells, which can provide basic data for the treatment of rheumatoid arthritis.
