Clinical study on acupuncture intervention time for treatment of peripheral facial paralysis / 中国针灸

<p><b>OBJECTIVE</b>To observe effects of intervention time of local acupuncture at the affected side on the facial nerve injury and the therapeutic effect at acute stage of peripheral facial paralysis.</p><p><b>METHODS</b>Two hundred and seventy-nine cases within 3 days of attack were randomly divided into 4 groups, group A (n=74), group B (n=70), group C (n=74) and control group (n=61). The 4 groups were treated with Prednisone on the third day after attack, and acupuncture was added in the group A, B and C, with Fengchi (GB 20), Yangbai (GB 14), Taiyang (EX-HN 5), Sibai (ST 2), Yingxiang (LI 20), etc. on the affected side and bilateral Hegu (LI 4) selected, and with superficial insertion method used for acupoints on the ear-face parts without manipulating the needles, and electroacupuncture was added from the fifth session of the treatment, and uniform reinforcing-reducing method was used for the distal acupoints selected. The needles were retained for 20 min and the treatment was given for 25 sessions, once other day. The therapeutic effects, the mean therapeutic courses for the cured patients and changes of electroneurography (ENoG) were compared among the groups.</p><p><b>RESULTS</b>The clinical total effective rate was 98.6%, 95.7%, 94.6% and 72.1% in the group A, B, C and the control group, respectively, with a significant difference (P < 0.05), and the therapeutic course for the cured patients increased in the order of the group A, B, C and the control group; and there was no significant difference among the 4 groups in changes of ENoG at the third day and the fourteenth day (both P > 0.05).</p><p><b>CONCLUSION</b>Acute stage is the best opportunity for acupuncture treatment of peripheral facial paralysis, and the earlier the intervention time, the better the therapeutic effect and the shorter the therapeutic course.</p>

Comparative studies of hemorheological parameters in Tibet mini-pigs, Beagle dogs and human / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the relationship of hemorheological parameters between Tibet mini-pigs, Beagle dogs and human.</p><p><b>METHODS</b>Blood samples were collected from adult Tibet mini-pigs, Beagle dogs and human to detect such hemorheological parameters as the whole blood viscosity (WBV) (high, middle, and low shear rate), PV, HCT, ESR and Fi.</p><p><b>RESULTS</b>The male Tibet mini-pigs had significantly lower WBV (150, 30, 5, and 1 s(-1)) and Fi than the female mini-pigs (P<0.05, 0.01, 0.05, 0.01, and 0.01, respectively). The WBV of male Beagle dogs (150 and 1 s(-1)) was significantly lower that in than female dogs (P<0.05). The WBV of male human subjects (1 s(-1)) and HCT were significantly higher, but ESR significantly lower than those in female human subjects P<0.05, 0.01 and 0.01, respectively). WBV (1 s(-1)), PV, and ESR in Beagle dogs were significantly lower, but HCT and Fi significantly higher than those in Tibet mini-pig and human subjects (P<0.05, 0.01, 0.05, and 0.01, respectively). All the hemorheological parameters were similar between Tibet mini-pigs and human (P<0.05).</p><p><b>CONCLUSION</b>The hemorheological parameters of Tibet mini-pigs are closer to those of human than those of Beagle dogs.</p>

Mitochondrial DNA D-loop variation types in Tibet mini-pigs in association with the blood parameters / 南方医科大学学报

<p><b>OBJECTIVE</b>To analyze the mitochondrial DNA (mtDNA) D-loop region sequence variation in Tibet Mini-Pigs in relation to the blood parameters and provide the molecular genetic basis for developing new species of laboratory animals.</p><p><b>METHODS</b>The genomic DNA was extracted from the whole blood samples of 59 Tibet mini-pigs to amplifying the mtDNA D-loop for sequence analysis. Nine physiological and nine biochemical blood parameters of Tibet mini-pigs were measured .</p><p><b>RESULTS</b>Based on the variation of the tandem repeat motif, the mtDNA D-loop region of Tibet mini-pigs was classified into two types, namely type A and B with the percentage of 57.6% and 42.4%, respectively, roughly matching the 3 transform sites (305, 500, 691) at the 5' end. In the 18 blood parameters, only red blood cell count showed significant differences between types A and (P<0.01).</p><p><b>CONCLUSION</b>Based on the sequence variation of the mtDNA D-loop region, Tibet mini-pigs can be divided into two types that show a significant difference in red blood cell count.</p>
