Effect of reinforcing qi for resolving masses method on expressions of MEK2 and p-ERK protein in estrogen induced uterine leiomyoma model guinea pigs' uterine tissue / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To explore the effect of reinforcing qi for resolving masses method (RQRMM) on expressions of extracellular signal regulated kinase 2 (MEK2) and phosphorylation extracellular signal regulated kinase (p-ERK) protein in estrogen induced uterine leiomyoma model Guinea pigs' uterine tissue.</p><p><b>METHODS</b>Guinea pigs were randomly divided into five groups, i.e., the model group, the high dose group, the middle dose group, the low dose group, and the Western medicine group (mifepristone). The normal control group was set up. The uterine leiomyoma model in guinea pigs was established by castrating and subcutaneous injecting estradiol (E2). The protein expression levels of MEK2 and p-ERK of guinea pigs' uterine tissues were detected by immunohistochemical assay.</p><p><b>RESULTS</b>The protein expressions of MEK2 and p-ERK in the uterine muscular tissue of Guinea pigs' uterine tissue were higher in the model group than in the normal group (P < 0.01). They decreased to some degree in the high dose group, the middle dose group, and the low dose group. Of them, the protein expressions of MEK2 and p-ERK were significantly lower in the high dose group than in the model group and the Western medicine group (P < 0.01).</p><p><b>CONCLUSION</b>RQRMM could treat uterine leiomyoma possibly through intervening the MAPK/ERK cell signal pathway to inhibit the proliferation of myoma cells.</p>

Effect of tongjingning granule on primary dysmenorrhea / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the mechanisms of tongjingning granule (TJN) on primary dysmenorrhea (PD).</p><p><b>METHODS</b>One hundred and twenty PD patients were treated with TJN, and 40 patients treated with aspirin as controls. The levels of serum estrogen (E2) and progestin (P) content in the luteal metaphase and anaphase (MI/AI) as well as endothelin (ET) and calcitonin gene related peptide (CGRP) in the metaphase and menstrual stage before and after treatment in partial patients were determined.</p><p><b>RESULTS</b>The therapeutic effect , and the curative markedly-effective rate and improvement rate of main accompanied symptoms of severe and moderate PD patients in the treated group were superior than those in the control group (P < 0.01). The level of E2 and ET were significantly decreased, and the content of P and CGRP were significantly increased in the treated group after treatment respectively (P < 0.01).</p><p><b>CONCLUSION</b>JTN not only can regulate ovarian hormone, ET and CGRP, but shows advantages in adjusting spirits and emotions, improving homeostasis and consolidating the therapeutic effect.</p>
