Speculation on optimal numbers of examined lymph node for early-stage epithelial ovarian cancer from the perspective of stage migration.

Introduction: In early-stage epithelial ovarian cancer (EOC), how to perform lymphadenectomy to avoid stage migration and achieve reliable targeted excision has not been explored in depth. This study comprehensively considered the stage migration and survival to determine appropriate numbers of examined lymph node (ELN) for early-stage EOC and high-grade serous ovarian cancer (HGSOC).

Methods: From the Surveillance, Epidemiology, and End Results database, we obtained 10372 EOC cases with stage T1M0 and ELN ≥ 2, including 2849 HGSOC cases.

Evaluation of clinical efficacy of continuous care with improved insulin injection techniques on patients with diabetes mellitus: a randomized controlled trial.

Objective: To investigate the clinical effect of continuous care with improved insulin injection techniques on patients with diabetes mellitus.

Methods: This randomized controlled trial enrolled patients with diabetes mellitus. They were randomly assigned to a control or observation group.

The electronic and optical properties of Al2O3, MO, and MAl2O4 (M = Zn, Mg).

The electronic properties and the imaginary parts of the dielectric function for nanosized ZnAl2O4 and MgAl2O4 are studied compared with those of B4-ZnO, B1-MgO and alpha-Al2O3 using a first-principles pesudopotential plane-wave method. The results show that both the electronic structures and the optical spectra of ZnAl2O4 and MgAl2O4 are different from those of ZnO, MgO and Al2O3 due to the atomic rearrangement, which agrees with the experimental data. The insight mechanism is also discussed.
