To observe the effects of preventative moxibustion on analgesia, substance P (SP), prostaglandin (PG) F2α and PGE2 in rats with dysmenorrhea due to cold-dampness stagnation, and to explore the analgesic mechanism. Sixty-four female Wistar non-pregnant rats were randomly divided into a blank group, a model group, a Western medicine group, and a preventative moxibustion group, with 16 rats in each group. Eight qualified diestrus rats were selected from each group. Except for the blank group, the other three groups established models of dysmenorrhea due to cold-dampness stagnation using an ice water bath combined with estradiol benzoate and oxytocin. On the 8th day after modeling, the preventative moxibustion group was treated with gentle moxibustion at Shenque (CV8) and Guanyuan (CV4), and the Western medicine group was given ibuprofen solution for 4 consecutive days. On the 11th day, the intervention groups (i.e. the Western medicine group and the preventative moxibustion group) were treated once again after being injected with oxytocin. The writhing score and the pain threshold of rats were determined; the serum levels of brain-derived neurotrophic factor (BDNF), SP, PGF2α, and PGE2 were measured; the mRNA and protein expression levels of BDNF and its receptor tropomyosin receptor kinase B (TrkB) in the spinal dorsal horn and hypothalamus were detected. Compared with the blank group, the writhing score increased (P<0.01), the pain threshold decreased (P<0.01), the serum levels of BDNF, SP, and PGF2α increased (P<0.01), while the PGE2 decreased (P<0.01); the protein and mRNA expression levels of BDNF and TrkB in the spinal dorsal horn and hypothalamus increased (P<0.01) in the model group. Compared with the model group, the writhing score decreased, the pain threshold increased, the serum BDNF, SP, and PGF2α levels decreased significantly, the serum PGE2 level increased, and the protein and mRNA expression levels of BDNF and TrkB in the spinal dorsal horn and hypothalamus decreased significantly in the preventative moxibustion group and the Western medicine group, while the inter-group differences were significant (P<0.01). Compared with the Western medicine group, the writhing score decreased, the pain threshold increased, the serum BDNF, SP, and PGF2α, levels decreased, the serum PGE2 level increased, and the protein and mRNA expression levels of BDNF and TrkB in the spinal dorsal horn and hypothalamus in the preventative moxibustion group decreased significantly, while the inter-group differences were significant (P<0.05 or P<0.01). Preventative moxibustion at Shenque (CV8) and Guanyuan (CV4) can improve the pain sensitization state of rats with dysmenorrhea due to cold-dampness stagnation, down-regulate the mRNA and protein expression levels of BDNF and TrkB in the spinal dorsal horn and hypothalamus; regulation of the serum SP, PGF2α, and PGE2 levels may be part of the mechanism.

To observe the effects of ginger-partitioned moxibustion at Shenque (CV8) and Guanyuan (CV4) on the expression levels of endocrine-related molecules and their receptors in rats with primary dysmenorrhea (PD) due to cold-dampness stagnation, thus to explore their analgesic mechanisms. Thirty-two female Wistar rats were divided into a normal group, a model group, a ginger-partitioned moxibustion group, and a Western medicine group according to the random number table method, with 8 rats in each group. Except for rats in the normal group, all other rats were treated with oxytocin combined with ice-water bath to establish the rat models of PD due to cold-dampness stagnation. After successful modeling, rats in the normal group and the model group did not receive treatment; rats in the ginger-partitioned moxibustion group received treatments with ginger-partitioned moxibustion at Shenque (CV8) and Guanyuan (CV4); rats in the Western medicine group received ibuprofen by intragastric administration. The writhing response of rats was compared among groups, and the serum levels of prostaglandin F2α (PGF2α), estrogen (estradiol, E2), progesterone (P), and the mRNA expression of PGF2α and E2 receptors in the uterine tissues were detected. No writhing behavior was observed in the normal group; compared with the normal group, the serum PGF2α and E2 levels in the model group were increased (P<0.01), while the P level was decreased (P<0.01), and the mRNA expression levels of the uterine PGF2α and E2 receptors were increased (P<0.01, P<0.05). Compared with the model group, the writhing behavior latency was prolonged, and the writhing response score was decreased in the ginger-partitioned moxibustion group and the Western medicine group (P<0.01); the serum PGF2α and E2 levels in the ginger-partitioned moxibustion group and the Western medicine group were decreased, while the P level was increased (P<0.05 or P<0.01); the mRNA expression levels of the uterine PGF2α and E2 receptors in the ginger-partitioned moxibustion group and the Western medicine group were decreased (P<0.05). Compared with the Western medicine group, the ginger-partitioned moxibustion group showed a prolonged writhing behavior latency, reduced writhing response score (P<0.05), and decreased serum E2 level (P<0.05), while no statistical differences in the serum PGF2α and P levels, or the mRNA expression levels of uterine PGF2α and E2 receptors (P>0.05). The analgesic effect of ginger-partitioned moxibustion on PD due to cold-dampness stagnation may be related to regulating the mRNA expression levels of PGF2α and E2 receptors in the uterine tissues.

Objective: To investigate the effect and mechanism of Bushen Huoxue formula on hippocampal cells apoptosis in rats with vascular dementia (VD ). Method: Totally 75 male SD rats were screened in Morris Water-maze screening, and then randomly divided into the sham-operated group, model group, Nimodipine group, Bushen Huoxue formula high and low dose (10.14, 5.07 g·kg ~1d 11 ) groups. Except the rats in the sham-operated group, all the other four groups received two-vessel occlusion (2-VO) method to establish VD models. The rats in the low-dose and high-dose Bushen Huoxue formula groups and the Nimodipine group received drugs Bushen Huoxue formula tablets and Nimodipine tablets respectively for 30 days. After treatment, all rats were tested by Morris Water-maze; brain hippocampal cells apoptosis was detected by TUNEL method and the expression levels of rat hippocampal extracellular signal-regulated kinase 2 (ERK2 ) and cAMP response element binding protein (CREB) were detected by immunohistochemistry and Western blot. Result: As compared with sham-operated group, the time of escape latency was significantly increased (P < 0.05 ); the number of passing platform and the stayed time in the former platform quadrant were both decreased (P <0.01); the integral absorbance (/A) of hippocampal cells apoptosis was significantly increased,and the average grey value was decreased significantly (P < 0.01 ); IA of hippocampal ERK2 and CREB (immunohistochemical) expression was significantly decreased, and the average grey value was significantly increased (P < 0.01 ); and the protein expression level (Western blot) was significantly decreased in model group (P < 0.01 ). As compared with the model group, Bushen Huoxue formula improved the learning and memory ability of rats, decreased the apoptosis IA (P <0.01 ),increased the average grey value (P < 0.01),and increased the IA and protein expression of ERK2 and CREB in hippocampal tissues (P < 0.05, P < 0.01 ) . Conclusion: Bushen Huoxue formula may inhibit apoptosis of hippocampal cells and improve the learning and memory ability of VD rats through regulating ERK/CREB signaling pathways in hippocampal tissues of rat.
