Surgical margin and other prognostic factors of invasive vulvar squamous cell carcinoma: A clinicopathological mono-center study.

Objective: To evaluate prognostic factors in women with invasive VSCC at Sun Yat-sen University Cancer Center (SYSUCC).

Methods: 137 patients with VSCC at SYSUCC were retrospectively analyzed. The Kaplan-Meier method assessed the overall survival (OS) and progression-free survival (PFS) time.

A novel fractional discrete grey model with variable weight buffer operator and its applications in renewable energy prediction.

With the continuous depletion of global fossil energy, optimizing the energy structure has become the focus of attention of all countries. With the support of policy and finance, renewable energy occupies an important position in the energy structure of the USA. Being able to predict the trend of renewable energy consumption in advance plays a vital role in economic development and policymaking.

piRNAs: biogenesis and their potential roles in cancer.

With the length of about 26-31 nt, PIWI-interacting RNA (piRNA) is a small non-coding RNA (ncRNA) that interacts with PIWI proteins to form the piRNA silencing complex (piRISC). PIWI is a subfamily of Argonaute, and piRNA must bind to PIWI to exert its regulatory role. Current studies indicated that piRNA and PIWI are significantly abnormally expressed in gastric, breast, kidney, colon, and lung cancers, and are involved in the initiation, progression, and metastasis of cancers, which may be the potential diagnostic tools, prognostic markers, and therapeutic targets for cancers.
