Relationships among immune traits and MHC B-LBII genetic variation in three chicken breeds / 生物工程学报

We have assessed the relationships between immune trait (antibody titers of Sheep red blood cell, SRBC; Avian influenza, AI; Newcastle disease, ND) and varieties of MHC B-LBHII Gene in local chicken breeds (Wenshang Barred chicken, LH; Laiwu Black chicken, LWH; and Jining Bairi chicken, BR). We selected 300 chickens randomly from the three indigenous chicken populations. The variations of MHC B-L BII gene were detected by directly DNA sequencing and polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). The results indicated that there were about 19-22 nucleotide mutations in the three local breeds, which could affect 16-18 amino acid variations. Another results indicated that there was significantly relationship between seven to eight SNPs of the MHC B-LBII region and some immune traits (P < 0.05 or P < 0.01). Both locus G97A and locus T138A were found in the three species, which were significantly related to the antibodies of SRBC, ND and AI antibody titers (P < 0.05). Among them, the locus G97A was significantly associated with ND antibody titers (P < 0.05) in BR chicken, with SRBC antibody titers (P < 0.05) in LWH chicken, and with H9 antibody titers (P < 0.05) in LH chicken. Furthermore, locus T138A was significantly associated with H9 antibody titers in BR and LH chickens (P < 0.05). All those results suggest relationships among the different varieties of MHC B-LBII and immune traits in the three local breeds.

Effect of Rehabilitation and Local Injection of Botulinum Aoxic A on Spastic Cerebral Palsy / 中国康复理论与实践

@#ObjectiveTo evaluate the efficacy of rehabilitation associated with local intramuscular injection of botulinum toxic A (BTX-A) on spastic cerebral palsy (CP).Methods60 children with spastic CP were divided into experimental group and control group with 30 cases in each group. Cases of experimental group were treated with rehabilitation associated with local intramuscular injection of BTX-A. Cases of control group were treated only with rehabilitation treatment. The therapeutic efficacies of two groups were evaluated with physician rating scale (PRS) and activities of daily living (ADL) evaluation systems.ResultsImprovement of clinical evaluations index-PRS and ADL in experimental group was much more significant than that of control group (P<0.05). ConclusionRehabilitation associated with local intramuscular injection of BTX-A can improve the efficacy of spastic CP.
