Objective To observe the influence of exterior-interior meridian acupoint selection on hippocampal cell apoptosis and c-Jun N-terminal kinase ( JNK) in ischemia-reperfusion injury rats, and to explore the possible protective mechanism for ischemia-reperfusion injury. Methods One hundred and twenty SD rats were randomly divided into sham-operation group (SH), model group (I/R), electroacupuncture (EA) group and JNK inhibitor SP600125 ( SP) group. The ischemia-reperfusion model was established by occlusion of middle cerebral artery with intraluminal thread. EA group was given EA on acupoints of Zusanli ( ST 36) , Sanyinjiao ( SP 6) , Chize ( LU 5) , Hegu ( LI 4) , once a day, based on the method of exterior-interior meridian acupoint selection. We observed the neurological behavioral changes by Longa neurological function standard, detected the activation of phosphorylated JNK ( p-JNK) by immunohistochemical method and examined the hippocampal apoptotic index by TUNEL method. Results The neurologic impairment scores of EA group and SP group were lower than I/R group (P<0.05) . Apoptotic index of I/R group was higher than SH group (P<0.01) and that of EA group and SP group was lower than I/R group (P <0.05) . The level of p-JNK in I/R group was higher than SH group ( P <0.01) and that of EA group and SP group was lower than I/R group ( P <0.05). Conclusion Exterior-interior meridian acupoint selection therapy has certain effect on alleviating neurologic impairment and reducing apoptosis in ischemia- reperfusion injury rats, and the mechanism might be associated with the inhibition of the activation of JNK signaling pathway.

Objective To investigate the distribution situation of ABO and Rh blood groups among Zhuang population in Nanning area to guide the scientific voluntary blood donor recruitment and rational storage of blood in this area.Methods 2 052 blood samples from Zhuang population in Nanning area were performed the identification of ABO and Rh blood groups.Whether the gene distributions conforming to the Hardy-Weinberg equilibrium principle was assessed by using the Chi-square test.The data was compared with the distribution characteristics in other areas or other minorities.Results The distribution characteristics of ABO blood groups in Nanning area were O > B> A > AB.Blood group O was highest (46.78%)and blood group AB was lowest (4.34%).The gene frequencies of A,B and O were 0.131 9,0.181 5 and 0.686 6,respectively.The blood groups distribution con-formed to the Hardy-Weinberg equilibrium principle;the RhD positive proportion(RhD+ )in Zhuang population was 99.90%,while the RhD negative (RhD- )proportion was 0.10%,which was lower than that in Han population.No phenotypes of ccdE,CcdE, CCdee,CCdE,CCDEE and ccDee were observed in this study.Conclusion The distribution of the ABO and Rh blood groups among Zhuang population in Nanning still maintains their own exclusive characteristics.The extremely low proportion of RhD- will bring about serious difficulties to the patients with long term blood transfusion.
