In this study, the active components and potential molecular .mechanism of Guizhi Fuling formula in treatment on dysmenorrhea, pelvic inflammation, and hysteromyoma were investigated using network pharmacological methods. Sterols and pentacyclic triterpenes, with high moleculal network degree, revealed promising effects on anti-inflammatory, analgesic, anti-tumor, and immune-regulation, according to D-T network analysis. On the other hand, the targets with high degree were involved in inflammatory, coagulation, angiopoiesis, smooth muscle contraction, and cell reproduction, which showed the novel function in anti-dysmenorrhea, pelvic inflammation, and hysteromyoma. Furthermore, the formula was indicated to play a key role in smooth muscle proliferation, inhibition of new vessels, circulation improvement, reduction of hormone secretion, alleviation of smooth muscle, block of arachidonic acid metabolism, and inflammation in uterus. Thus, the main mechanism of Guizhi Fuling formula was summarized. In conclusion, Guizhi Fuling formula was proven to alleviated dysmenorrhea, pelvic inflammation, and hysteromyoma by acting on multiple targets through several bioactive compounds, regulating 21 biological pathways.

The Mediator Complex plays key roles in activating gene transcription in eukaryotes. Mediator of RNA polymerase II transcription subunit 12 homolog (MED12) is a subunit of the Mediator Complex and regulates the activity of the complex. MED12 is involved in a variety of cellular activities, and mutations in MED12 gene impair MED12 activities and are associated with several diseases, including Opitz-Kaveggia syndrome, Lujan syndrome, uterine leiomyomas and prostate cancer. This review will discuss the biological function of MED12 and the relationship between MED12 mutations and diseases.

OBJECTIVETo study the clinical and pathologic features of gastric schwannomas.

METHODSThe macroscopic and microscopic features of 9 cases of gastric schwannoma were analyzed. Immunohistochemical study for S-100 protein, CD117, CD34, neurofilament, desmin, nestin, glial fibrillary acidic protein, platelet derived growth factor-alpha (PDGFR-α) and vimentin was carried out. Mutation analysis of c-kit gene (exon 9, 11, 13 and 17) and PDGFR-α gene (exon 12 and 18) in 1 case was examined by PCR amplification and direct sequencing.

RESULTSThe patients included 5 males and 4 females. The age of patients ranged from 42 to 81 years (median = 56.5 years). The size of the tumors ranged from 2 to 9 cm in greatest diameter. Follow-up data in 8 cases (from 1 month to 65 months) showed no evidence of recurrence or metastasis. Gross examination showed that gastric schwannomas were homogeneous, firm, yellow-white and bore no true fibrous capsule. Histologically, all cases were composed of fascicles of spindle cells associated with nuclear palisading, Verocay body formation and peripheral cuff of reactive lymphoid aggregates. Some of them showed degenerative changes including cyst formation, calcification, hemorrhage, necrosis and hyalinization. Immunohistochemical study showed that the tumor cells were strongly positive for S-100 protein and vimentin. There was various degree of staining for nestin (8/9) and glial fibrillary acidic protein (6/9). They were negative for CD117, CD34, neurofilament, desmin and smooth muscle actin. One case showed focal positivity for PDGFR-α (1/9), with no mutations found.

CONCLUSIONSGastric schwannomas share similar histologic features with conventional soft tissue schwannomas, in addition to the presence a reactive lymphoid cuff. The clinical, macroscopic, histologic and immunohistochemical features of gastric schwannomas were different from those of gastrointestinal stromal tumors and leiomyomas.
