Objective To explore the significance of signal and volume change from magnetic resonance imaging (MRI) of hysteromyoma before and after uterine artery embolization (UAE) in the therapy evaluation. Methods MRI was performed in 30 patients (50 hysteromyoma) before and 3,6 and 12 months after UAE. They were grouped by location, signal and size. The MRI signal changes and the hysteromyoma's volume reduction ratio were measured. Results After 3,6,12 months, MRI of hysteromyoma was changed significantly, and all hysteromyomas had lower T2WI signals than before, some of which had higher T1WI signals. Hysteromyoma's volumes were progressively reduced, the majority of which shrinked significantly within 3 months. Evaluated by 12 month's volume changes, significant volume reduction was found in submucous fibroids, and significant difference was showed compared with intramural fibroids and subserosal fibroids (88.9 % vs. 73.7 % and 68.3 %, P=0.036, P=0.019), meanwhile,the latter two had no significant difference (P=0.384). The volume reduction rate in rich cell fibroids was higher than those in ordinary no degeneration fibroids and degeneration type, and there were significant differences (85.7 % vs. 72.1 % and 63.4%, P=0.038, P=0.014). Besides, the latter two had no significant difference (P=0.364). Large fibroids shrinked more obviously than small ones with significant difference (75.2 % vs. 59.6 %, χ2=4.563, P=0.044). Conclusion MRI is useful for the evaluation of efficacy in hysteromyoma before and after UAE, which can provide the better interventional treatment for the patients in regard to different sensitivity of hysteromyoma to UAE.

Objective To investigate the therapeutic effect,safety and its prognostic factors of capecitabine as maintenance treatment agent for prolonging the PFS of patients with recurrent and metastatic breast cancer after they received combination chemotherapy.Methods From January 2011 to June 2013,38 cases with recurrent and metastatic breast cancer were collected in the department of medical oncology of the First Hospital of Lanzhou University.All the 38 patients received NX scheme (vinorelbine combined capecitabine chemotherapy),and some patients among of them had stabile disease after chemotherapy and were administered X scheme (capecitabine,twice a day,2 000 mg/m2 daily,withdrawal for 7 days after a consecutive intake of 14 days,21 days as a cycle,at least 2 cycles) until disease progressed or toxicity could not be tolerated.Adverse reactions and PFS were observed and recorded.Single factor chi square test and multivariate COX proportion hazard model were used to evaluate the relationships between clinic features and RR,PFS.Results The overall response rate (CR + PR) was 55.26％ (21/38),clinical benefit patients rate (CR + PR + SD) was 84.2％ (32/38),with 4 patients of CR (4/32),17 patients of PR,11 patients of SD,6 patients of PD.Thirty-two no progressived patients were administered capecitabine until PD.The median PFS was 10.0 months.Stratification analysis showed that patients whose Karnofsky (KPS) ≥80 had an average PFS of 14.1 months,while an average PFS of 6.8 months for patients whose KPS ＜ 80,with a statistical significance (x2 =6.251,P =0.000).Cox proportion hazard model also showed that age (RR =3.561,95％ CI:1.372-5.216,.x2 =4.025,P =0.031),menopausal status (RR =1.895,95 ％ CI:1.124-4.452,x2 =5.725,P =0.048),KPS score (RR =4.553,95％ CI:1.131-7.703,x2 =11.205,P =0.005),the number of metastasis (RR =5.781,95％ CI:2.321 ～11.243,x2 =3.925,P =0.011) were important prognostic factors for the patients with breast cancer.Major treatment-related adverse reaction was grade Ⅰ-Ⅱ hand-foot syndrome.One patient discontinued treatment because of grade Ⅲ hand-foot syndrome.Conclusion Capecitabine as maintenance treatment can significantly prolong the PFS of patients with recurrent and metastatic breast cancers at remission or stable stage after combination chemotherapy with a better tolerance.Age of patients,menopausal status,KPS score,the number of metastasis are the prognostic factors for the efficacy of NX-X regimen.

Peptide drugs exhibit an irreplaceable role in clinics due to their high specificity, efficiency and low toxicity. At present, more than 80 peptide drugs have been approved for marketing with global sales exceeding $50 billion in 2019. However, with large molecular weights, high hydrophilicity and instability in digestive tract, oral peptide drugs encounter substantial physiological barriers leading to low oral bioavailability. Therefore, peptide drugs are mostly administered by parenteral routes. Although parenteral delivery of peptide drugs achieves high bioavailability, this is associated with inconvenience and discomfort, even causing severe side effects compared with the oral route possessing a high degree of patient compliance. Therefore, numerous studies concentrate on novel strategies to improve the oral bioavailability of peptide drugs. Some delivery technologies such as Eligen™ and Axcess™ have been successfully applied to the oral dosage form of therapeutic peptides and have accelerated relevant oral formulations for Food and Drug Administration (FDA) approval and clinical treatment. In this review, we focus on the oral peptide delivery, mainly summarizing the progress of recent strategies used to overcome oral barriers and the commercialization applications of related patents, which could facilitate the research and development (R&D) of clinical applications of oral delivery techniques for peptide drugs.
