OBJECTIVETo explore the efficacy and the reproductive endocrinal mechanism of herbal-partitioned moxibustion in the treatment of primary dysmenorrhea.

METHODSOne hundred and seventy-one cases of primary dysmenorrhea were randomized into an herbal-partitioned moxibustion group (group A), an starch-partitioned moxibustion group (group B) and an acupuncture group (group C), 57 cases in each one. In the group A, moxibustion isolated with herbal medicine was applied to Shenque (CV 8). In the group B, moxibustion isolated with starch was used at Shenque (CV 8). In the group C, acupuncture was given at Sanyinjiao (SP 6). The changes of estradiol (E2), progesterone (P) and prostaglandin levels (PGF2alpha) were observed before and after treatment, and the therapeutic effects were compared among the 3 groups.

RESULTSThe therapeutic effect in the group A was better than those in the other two groups [compared the cured rate: 89.8% (44/49) vs 60.0% (30/50), 60.4% (32/53), both P < 0.05]. In the group A, E2 level [(110.99 +/- 12.90) pg/mL vs (83.94 +/- 8.91) pg/mL, P < 0.05] and PGF2alpha level [(24.58 +/- 3.01) pg/mL vs (14.34 +/- 1.48) pg/mL, P < 0.01] were decreased and P level was increased [(4.65 +/- 0.68) ng/mL vs (6.68 +/- 0.95) pg/mL, P < 0.05]. In the group B and C, PGF2alpha level were reduced. Concerning to the regulating of E2 and PGF2alpha levels, the results in the group A were better than those in the group B and C [(-30.16 +/- 10.20) pg/mL vs (10.79 +/- 15.01) pg/mL, (22.81 +/- 12.22) pg/mL; (-13.10 +/- 2.40) pg/mL vs (-6.52 +/- 1.88) pg/mL, (-3.14 +/- 1.19) pg/mL, (see text) P < 0.05]. Concerning to the regulation of P level, the results in the group A and B were better than that in the group C (all P < 0.05).

CONCLUSIONThe herbal-partitioned moxibustion achieves the significant efficacy on primary dysmenorrhea, which could be related to regulating the reproductive endocrinal level. It decreases E2 and PGF2alpha levels and increases P level.

This study was to investigate the effect of peoniflorin on the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream signal molecules in the hippocampus of Alzheimer's disease (AD) rats for exploring the mechanism of peoniflorin protecting hippocampal neurons. AD model rats were established by bilateral intrahippocampal injection of beta-amyloid(1-42) (Abeta(1-42)) and divided randomly into 3 groups: AD model group, peoniflorin low-dose (15 mg x kg(-1)) group and peoniflorin high-dose (30 mg x kg(-1)) group. The vehicle control rats were given bilateral intrahippocampal injection of solvent with the same volume. After peoniflorin or saline was administered (ip) once daily for 14 days, the hippocampuses of all animals were taken out for measuring the expressions of Nrf2, heme oxygenase-1 (HO-1) and gamma-glutamylcysteine synthethase (gamma-GCS) mRNA by reverse transcription PCR, determining the contents of glutathione (GSH), malondialdehyde (MDA) and carbonyl protein (CP) using colorimetric method, and for assaying the expressions of neuronal apoptosis inhibitory protein (NAIP) and Caspase-3 by immunohistochemical staining method. The results showed that peoniflorin markedly increased the expressions of Nrf2, HO-1 and gamma-GCS mRNA, enhanced the level of GSH and decreased the contents of MDA and CP in the hippocampus, as compared with the model group. Peoniflorin also improved the NAIP expression and reduced the Caspase-3 expression in the hippocampus neurons. In conclusion, peoniflorin protects against the Abeta(1-42)-mediated oxidative stress and hippocampal neuron injury in AD rats by activating the Nrf2/ARE pathway.

OBJECTIVETo investigate the protective effect of paeonol on amyloid beta1-42 (Abeta1-42)-induced neurotoxicity and its mechanism.

METHODHippocampal neurons of well-grown newborn SD rats and differentiated SH-SY5Y cell lines were cultured with various concentrations of paeonol (1, 5, 10 micromol x L(-1), respectively) for 6 hours and then incubated with Abeta1-42 oligomer (30 micromol x L(-1)) for 24 hours and 48 hours, respectively. The neuron apoptosis was observed by Heochst33258. Annexin V/PI double stain flow cytometry assay was adopted for determining SH-SY5Y cell apoptosis rate. And the expression of BDNF and Bcl-2 mRNA was detected by RT-PCR.

RESULTCompared with the model group, various concentrations of paeonol (1, 5, 10 micromol x L(-1)) significantly reduced the hippocampal neurons karyopycnosis, decreased the rate of SH-SY5Y cell apoptosis to 22.4%, 18.1% and 16.4%, respectively, and improved the expressions of BDNF and Bcl-2 mRNA.

CONCLUSIONPaeonol relieves Abeta1-42 oligomer-induced neuron injury by increasing BDNF and Bcl-2 expressions.
