Therapeutic observation of tuina manipulation for lumbar intervertebral disc herniation / 针灸推拿医学（英文版）

Objective:To observe the clinical efficacy of balance-impact tuina therapy for lumbar intervertebral disc herniation (LIDH).Methods:A total of 118 eligible LIDH patients were randomized into an observation group and a control group by the random number table method,with 59 cases in each group.The observation group was intervened by balance-impact tuina therapy,while the control group was intervened by conventional tuina therapy,both for consecutive two weeks.The scores of visual analog scale (VAS),Oswestry disability index (ODI),quality of life questionnaire-core 30 (QOL-C30) were observed before and after treatment;the relapse rate was estimated at the sixth month and twelfth month following the treatment.The data were statistically analyzed.Results:After intervention,the total effective rate was 96.6％ in the observation group versus 91.5％ in the control group,and the between-group difference was statistically significant (P＜0.05).The VAS and ODI scores declined significantly after treatment in both groups (all P＜0.05),and the observation group was markedly lower than the control group (P＜0.05,P＜0.01).The QOL-C30 score increased significantly after treatment in both groups (both P＜0.05),and the observation group was markedly higher than the control group (P＜0.05).The relapse rates at the post-treatment sixth month and twelfth month in the observation group were lower than those in the control group (P＜0.05,P＜0.01).Conclusion:Compared with the conventional tuina therapy,the balance-impact tuina therapy shows advantage in lessening pain,improving the function and enhancing the quality of life in the treatment of LIDH,and it has a lower relapse rate.Thus,this therapy is worth promoting in clinic.

Effect of muscle-tension-balance acupuncture therapy on the motor function and living ability of patients with drop foot and strephenopodia after stroke / 中国针灸

<p><b>OBJECTIVE</b>To compare the difference between muscle-tension-balance acupuncture and conventional acupuncture in the impacts on motor function and living ability of patients with drop foot and strephenopodia after stroke.</p><p><b>METHODS</b>Seventy cases were randomly divided into a muscle-tension-balance acupuncture group (group A) and a conventional acupuncture group (group B), 35 cases in each one. In group A, firstly the acupuncture of weakening technique was applied to Sanyinjiao (SP 6) and Taixi (KI 3) on the musculus extensor side; secondly, the strengthening technique was adopted at Jiexi (ST 41), Shenmai (BL 62) and Yanglingquan (GB 34) on musculus flexor side. In group B, the conventional needling technique was applied to Zusanli (ST 36), Sanyinjiao (SP 6), Xuanzhong (GB 39), etc. The treatment was given once every day in either group, 10 treatments made one session and 3 sessions of treatment were required. The score of Fugl-Meyer motor function of the lower limb on the affected side and Barthel index score were assessed before and after treatment in two groups.</p><p><b>RESULTS</b>After treated for 3 sessions, Fugle-Meyer motor function score and Barthel index score of the patients all increased in two groups (all P < 0.01). The results in group A were better than those in group B (both P < 0.05). The improvements were apparent in the 2nd session of treatment in group A (both P < 0.01), which were superior to those in group B (both P < 0.05).</p><p><b>CONCLUSION</b>Either acupuncture therapy can improve the motor function and living ability of patients with drop foot and strephenopodia after stroke. The muscle-tension-balance acupuncture achieves the efficacy quickly and its efficacy is much better.</p>

Estrogen receptor α and β expressions in hypothalamus-pituitary-ovary axis in rats exposed lactationally to soy isoflavones and bisphenol A / 生物医学与环境科学（英文）

<p><b>OBJECTIVES</b>This paper aims to investigate the uterotrophic activities of lactational exposure to combination of soy isoflavones (SIF) and bisphenol A (BPA) and to examine estrogen receptor α (ERα) and estrogen receptor β (ERβ) expressions in hypothalamus-pituitary-ovary axis and uterus.</p><p><b>METHODS</b>Maternal rats that were breeding about 8 litters were randomly divided into four groups with seven dams in each group. Dams in different treatment groups received corn oil (control), 150 mg/kg BW of SIF, 150 mg/kg BW of BPA or combination of 150 mg/kg BW of SIF and 150 mg/kg BW of BPA, respectively, from postnatal day 5 to 11 (PND5-11) by gavage. On PND12 and PND70, 10 female litters were killed and hypothalamus, pituitary, ovary and uterus were collected. ERα and ERβ expressions in these organs were detected with Western blotting assay. And vaginal opening time and estrus cycle were examined in animals fed for PND70.</p><p><b>RESULTS</b>On PND12, the relative uterine weight of rats treated with ISF or BPA or their combination was significantly higher than that of untreated rats (P<0.05). But the relative uterine weight of rats in the co-exposure group was slightly lower than that in the group only exposed to SIF or BPA. On PND 70, however, the relative uterine weight in each treatment group was not statistically different from that in the control group (P>0.05). Vaginal opening time and estrus cycle in groups treated with SIF or BPA or their combination were similar to those in the control group (P>0.05). Exposure to SIF or BPA or their combination could up-regulate or down-regulate ERα and ERβ expressions in hypothalamus, pituitary, ovary and uterus on PND12 and PND70. These regulation patterns for ERα and ERβ were different in different organs at different time points.</p><p><b>CONCLUSION</b>Lactational exposure to ISF or BPA or their combination could induce uterotrophic responses in neonate rats, which disappeared in later life. But these data fail to suggest a possibility for synergic actions between SIF and BPA. It was also demonstrated that the uterotrophic effects of SIF and BPA exposure might, at least, involve modification of ERα or ERβ expressions in the hypothalamus-pituitary-ovary axis.</p>

Effect of baicalin on HSP70 expression of hippocampal neurons in focal brain ischemia-reperfusion injury rats / 药学学报

<p><b>AIM</b>To investigate the effect of baicalin on the hippocampal neuronal apoptosis and the expression of HSP70 in rats with focal brain ischemia-reperfusion injury.</p><p><b>METHODS</b>One hundred and twenty male Wistar rats were randomly divided into six groups:sham operated group, ischemia-reperfusion group, nimodipine group and three baicalin groups,to which baicalin was administered at doses of 50, 100 and 200 mg x kg(-1), separately. The models of focal brain ischemia-reperfusion injury induced by middle cerebral artery occlusion (MCAO) were used in this study. HE stain was used to observe the pathological changes. Flow cytometry (FCM) was used for determination of neuronal apoptosis. HSP70 protein expression of the neurons was detected with immunohistochemistry. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the expression of the mRNA level of HSP70.</p><p><b>RESULTS</b>Baicalin can significantly relieve the pathological changes and inhibit apoptosis in hippocampus CA1 area, and at the same time increase the expression of HSP70 and HSP70 mRNA.</p><p><b>CONCLUSION</b>Baicalin can relieve brain damage induced by focal brain ischemia-reperfusion in rats, which may be related to inhibiting the process of the neuronal apoptosis. The mechanism of antiapoptosis effect of baicalin may be related to the promotion of transcription of HSP70 mRNA and increasing the expression of the protein.</p>
