OBJECTIVE:To study the effects of Tibetan medicine Zuotai on the activities of cytochrome oxidase (CYP1A2) and drug metabolism enzyme N-acetyltransferase 2(NAT2)in rats. METHODS:70 SD rats were equally randomized into a normal control (normal saline) group,the groups of single administration of low,middle and high-dose (1.2,3.8 and 12 mg/kg) Zuotai and the groups of multiple administrations thereof(once daily for 12 consecutive days). The rats were given drugs ig. caffeine(25 mg/kg)was given ig to the rats in the normal control group and the groups of single administration on the 2nd day,and to those in the groups of multiple administrations on the 13th day. 5 h later,their urine was collected and added with vitamin C based on 10 mg/ml. High performance liquid chromatography (HPLC) was adopted to determine the cafeine metabolites contents of 5-acetami-do-6-formamido-3-methyl-uric acid(AFMU),1-methylxanthine(1X),1-methyl-uric acid(1U)and 1,7-dimethyl uric acid(17U) in rats’urine,and the activities of CYP1A2 and NAT2 were reflected through (AFMU+1X+1U)/17U and AFMU/(AFMU+1X+1U). RESULTS:Compared with normal control group,the(AFMU+1X+1U)/17U and AFMU/(AFMU+1X+1U)in rats were de-creased,namely the activities of CYP1A2 and NAT2 were lower in the groups of single administration of middle-dose Zuotai and multiple administrations of middle and high-dose Zuotai than in the normal control group. There was statistical difference (P<0.05). CONCLUSIONS:Zuotai can obviously inhibit the activities of CYP1A2 and NAT2 in rats.

OBJECTIVE To investigate the effect of new baicalin(BC) metal ions(Co2+,Cu2+, and Ni2+)complexes(BMCs)on ion channels Kv1.4 and Cav3.2. METHODS HEK293 or CHO cells loaded with various ion channels(hERG,Kv1.2,Kv1.3,Kv1.4,Kv1.5,Kv1.6,Kv1.7,Kv1.8,Kir1.1, Kir2.1,KCNQ and Cav3.2)were obtained by stable transfection method. Whole-cell patch-clamp tech?nique was used to record current changes of each ion channel induced by BC and BMC in 10μmoL · L-1. The effect of different concentrations(0.3,1,3,10 and 30μmoL · L-1)of BC-Co and BC-Cu on Kv1.4 and Cav3.2 current was detected by whole-cell patch-clamp technique. RESULTS A model of HEK293 cells or CHO cells that stably expressed various ion channels was obtained. BMCs (BC-Co,BC-Cu and BC-Ni)had some impact on various ion channels,especially on Kv1.4 and Cav3.2. The inhibitory rate induced by BC-Co,BC-Cu and BC-Ni(10 μmol · L-1)was 91%,76% and-10%,respectively,for Kv1.4;and 43%,57%and-14%,respectively,for Cav3.2. IC50 of BC-Co was 1.69 and 0.81μmoL·L-1 for Kv1.4 and Cav3.2. IC50 of BC-Cu was 1.66 and 0.58μmoL · L-1 for Kv1.4 and Cav3.2. CONCLUSION BC-Cu and BC-Co concentration-dependently inhibit Kv1.4 and Cav3.2 ion channels.

Background Chemical crosslinking agent can be used to strengthen the intensity of sclera tissue,but the intensity of the sclera may be influenced by different crosslinking methods.Objective The aim of this study was to compare the effectiveness of collagen crosslinking on porcine sclera between whole-eye crosslinking method and scleral strip crosslinking method.Methods Whole-eye crosslinking or sclera strip crosslinking was performed on 70 fresh porcine eyeballs in five groups using 1％ genipin,1％ glutaraldehyde or PBS respectively for 40 minutes.After crosslinking,10 sclera strips with l0 mm×4 mm from the temporal lateral were prepared in every group for the stress-strain measurement using a Instron5848 microtester,and the other 4 scleral strips in each group were extracted for the thermal shrinkage temperature test.Results Biomechanical property test reveled that the elastic modulus value of sclera strips reduced by 70.0％-82.8％ in the whole-eye crosslinking method group compared with scleral stip crosslinking method group after treated with 1％ genipin ((8.98 ± 1.81) MPa vs.(10.85 ± 1.83) MPa,t =3.375,P =0.003)) and 1％ glutaraldehyde((12.78 ±2.91) MPa vs.(18.25 ±5.16) MPa,t =4.007,P =0.001)) ;The tensile stress of whole-eye crosslinking method group was 54.9％-90.1％ of scleral stips method group,showing significant decline after corsslinked of whole-eye in 5％,10％,15％ and 20％ strain conditions (all P ＜ 0.05).Thermomechanics test showed that the thermal shrinkage temperature was lower in the whole-eye crosslinking group compared with scleral stip crosslinking group after treated with both 1％ genipin ((68.8 ±0.9)℃ vs.(74.8± 1.3)℃,t=11.129,P=0.000)) and 1％ glutaraldehyde((73.3±0.9)℃ vs.(79.3±1.3)℃,t=11.112,P=0.000)).Conclusions Different crosslinking methods have an influence on the efficacy of collagen crosslinking on porcine sclera.Sclera strip crosslinking offers a better crosslinking intensity for selera.

OBJECTIVETo compare the difference in the clinical efficacy on posterior circulation ischemia between acupuncture at stellate ganglion and conventional acupuncture as well as the impacts on blood pressure.

METHODSEighty cases of posterior circulation ischemia were randomized into an observation group (40 cases) and a control group (40 cases). In the observation group, acupuncture was applied to the bilateral stellate ganglions on the neck, stimulated with reinforcing technique by rotating the needles. In the control group, the acupuncture of reducing technique was applied to Fengchi (GB 20), Baihui (GV 20), Neiguan (PC 6) and Taichong (LR 3) in the excess syndrome. The even needling or reinforcing technique was applied to Fengchi (GB 20), Baihui (GV 20), Ganshu (BL 18), Shenshu (BL 23) and Zusanli (ST 36) for the deficiency syndrome. The treatment was given once every 3 days and 4 treatments were required totally in the two groups. The changes in total syndrome score, peak Systolic blood flow velocity (Vp) of vertebral artery and basilar artery, systolic and diastolic blood pressures were compared before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSThe total syndrome score was reduced apparently after treatment compared with that before treatment in the two groups (P < 0.01), and the reducing was more obvious in the observation group as compared with that in the control group (P < 0.01). The total effective rate was 87.5% (35/40) in the observation group, higher than 67.5% (27/40, P < 0.05) in the control group. After treatment, the reduced Vp of vertebral artery was not improved apparently as compared with that before treatment in the control group, Vp in blood velocity abnormality (including vascular spasm, stenosis or reduced velocity) of vertebral artery and basilar artery was all improved as compared with that before treatment in the two groups (P < 0.01), and the improvements in the observation group were more obvious than those in the control group (P < 0.01). After treatment, the systolic and diastolic pressures were reduced as compared with those before treatment in the two groups, and the reduced systolic and diastolic pressures in the observation group were more apparent than those in the control group (P < 0.01).

CONCLUSIONAcupuncture at stellate ganglion achieves the satisfactory efficacy in the treatment of posterior circulation ischemia and the significant efficacy of reducing blood pressure, more advanced than the conventional acupuncture.
