AIMTo investigate the change of NMDAR1 (zeta 1) subunit expression in temple cortex, frontal lobe, hippocampus and cerebellum of three different group rat after 98 dB wide frequency noise exposure.

METHODSWestern Blot and RT-PCR technique, combined with auditory brainstem response (ABR) measurement.

RESULTS(1) Expressions of NMDAR1 (zeta 1) subunit in frontal cortex, temple cortex, hippocampus and cerebellum have no difference, but AD model rat is much weaker than the control group. (2) Expression of NMDAR2A (epsilon 1) in temple cortex for physiological saline groups rat have a mostly increase (plus noise), moreover, those are weakest expression in hippocampus. NMDAR1 (zeta 1) subunit in cerebellum have highest expression, moreover, it is weakest in temple cortex. (3) NMDAR1 (zeta1), NMDAR2A (epsilon 1) subunit expression in hippocampus for three groups rat have a down-regulation after adding noise. (4) NMDAR1 (zeta 1), NMDAR2A (epsilon 1) subunit mRNA expression in control group have no remarkable difference in different cortex. (5) Expressions of NMDAR2A (epsilon 1) in frontal temple cortex, hippocampus for AD model rat are less than that of other groups, weakest in cerebellum, weaker in frontal.

CONCLUSIONWide band frequency noise can reduce the expression of NMDAR1 (zeta 1) subunit in hippocampus and cerebellum of AD model rat, however, the way of regulation is not in the mRNA level. Wide band frequency noise can inhibit the expression of NMDAR2A (epsilon 1) in hippocampus, temple cortex of AD model rat, which has been regulated by mRNA level and have cortex area difference.

In 2012, the preparation process and quality standard for Guizhi Fuling capsule were improved. To compare the effects and differences of capsules before (2011) and after(2012-2014) the improvement, evaluation models for intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma were applied in rats. Models were induced by oxytocin, liqiud bacteria mixture and estrogen loading, respectively. The capsules (12 batchs/year, 48 bathcs in all), sampled randomly in 2011-2014, the effects were assessed using the three models. In anti-dysmenorrhea models, remarked reduction of writhing frequency, ET-1 and PGF2α content in uterus could be detected, as well as extension of writhing latency. In pelvic inflammation rats, depression of TNF-α and raise of IL-2 were induced by earh batch of capsules. In hysteromyoma model, uterine weight and smooth muscle proliferation, including E2 and P level in plasma, were lowered obviously by all batchs of capsules. Secondly, Guizhi Fuling capsules produced in 2012-2014 revealed better effectiveness than the ones manufactured in 2011. Moreover, pharmacodynamics indexes of the samples made in 2011 differed significantly between groups, which could not be observed in the ones ot 2012-2014. After tne preparation process and quality standard improvement, the effectiveness and homogeneity of Guizhi Fuling capsules were enhanced.

AIMTo determine the exact roles of prolactin (PRL) in the pathogenesis of rheumatoid arthritis (RA) and supply experimental basis for clinical treatment of RA, and to investigate the expression of matrix metalloproteinase-9 (MMP-9) in the synovium of adjuvant arthritis rats.

METHODSForty rats were divided into four groups (n = 10): (1) Normal control group (group A); (2) Adjuvant arthritis control group (group B); (3) Hyperprolactinemic adjuvant arthritis group (group C); (4) Hypoprolactinemic adjuvant arthritis group (group D). The content of PRL in the serum was detected by radio-immunoassay method. The activity of MMP-9 was analyzed by gelatin zymography. The alteration of MMP-9 immunoreactivity were investigated by means of immunohistochemistry in the synovium of all groups. The expressions of MMP-9 were investigated by Western blot in the synovium of all groups.

RESULTSCompared with group A, the activity and expression of MMP-9 of group B in the synovium were highly increased. The activity and expression of MMP-9 in the synovium were the most distinctive in group C. Compared with group B, the activity and expression of MMP-9 in the synovium were decreased in group D, but still higher than group A.

CONCLUSIONThe present results indicated that PRL might involved in the pathogenesis of RA by regulating the secretion of MMP-9 in the synovium.
