To establish murine graft versus host disease (GVHD) model, in order to evaluate the efficacy of human CD40 Ig fusion protein treatment. To establish murine GVHD model, 2 5?10 7 or 5 0?10 7 /L spleen cells of male C57BL/6 mice were intravenously injected into female BALB/c mice, as receipt, respectively, after sub lethally irradiation by 60 Co source. After the induction of GVHD, human CD40 Ig fusion protein was intravenously injected three times at a dose of 50?g, 150?g and 450?g on day 0, 2 and 4, respectively. The results showed that the typical expressions of GVHD were observed 4 or 5 days after the injection of donor spleen cells, and specific male Y chromosome fragment was amplified by genomic PCR in female BALC/c receipts. The mean survival time (MST) of GVHD induced mice was significantly prolonged by the treatment of human CD40 Ig fusion protein. It is suggested that Murine GVHD model successfully established can be used in evaluating the effects of anti GVHD therapies.

Objective: To observe the effects of electroacupuncture (EA) on uterine prostaglandin F2α (PGF2α), cyclooxygenase 2 (COX-2) and nuclear factor κB (NF-κB) in rats with primary dysmenorrhea (PD) and to discuss the possible mechanism in EA intervening PD. Methods: Forty Sprague-Dawley female rats were randomly divided into a blank group, a model group, an EA group and an ibuprofen group, with 10 rats in each group. The PD model was established using estradiol benzoate combined with oxytocin in the model group, EA group and ibuprofen group. At the same time of modeling, rats in the EA group were given EA at Guanyuan (CV 4) and Sanyinjiao (SP 6) once a day for 20 min each time for 10 consecutive days. Ibuprofen was intragastrically administered once a day for 10 consecutive days in the ibuprofen group. The same amount of normal saline was intragastrically administered once a day for 10 consecutive days in the blank group and model group. The number of writhing of rats in each group within 30 min was compared on the 11th day just after the interventions. The uterine homogenate supernatant was separated and the PGF2α level was detected by enzyme-linked immunosorbent assay. Western blot was applied for the detection of the expression levels of COX-2, phospho-NF-κB p65 and NF-κB p65 proteins in uterine tissues. Results: Compared with the blank group, the number of writhing in the model group increased significantly (P<0.01), and the expression levels of PGF2α, COX-2, phospho-NF-κB p65 and NF-κB p65 proteins in uterine tissues were significantly increased (all P<0.01). Compared with the model group, the number of writhing in the EA group and ibuprofen group were significantly reduced (both P<0.01), and the expression levels of PGF2α and COX-2 protein in uterine tissues were significantly reduced (both P<0.01). Compared with the model group, the phospho-NF-κB p65 level in uterine tissues in the EA group was significantly reduced (P<0.01). Compared with the ibuprofen group, the phospho-NF-κB p65 level in the EA group was significantly reduced (P<0.01). Conclusion: The mechanism of EA for PD rats may be related to inhibiting the phosphorylation of NF-κB and reducing the levels of COX-2 and PGF2α in uterine tissues.
