The Effects of Near-Infrared Phototherapy Preirradiation on Lower-Limb Muscle Strength and Injury After Exercise: A Systematic Review and Meta-analysis.

Objective: To assess near-infrared preirradiation effects on postexercise lower-limb muscle damage and function and determine optimal dosage.

Data Sources: PubMed, Embase, Cochrane Library, EBSCO, Web of Science, China National Knowledge Infrastructure, and Wanfang Data were systematically searched (2009-2023).

Study Selection: Randomized controlled trials of near-infrared preirradiation on lower-limb muscles after fatigue exercise were incorporated into the meta-analysis.

Prognoses in patients with primary gastrointestinal neuroendocrine neoplasms based on the proposed new classification scheme.

Aim: The aim of this study is to investigate the clinicopathological characteristics, as well as explore the prognostic accuracy of the proposed new classification in gastrointestinal NENs (GI-NENs) patients.

Methods: Patients diagnosed with GI-NENs were retrospectively indentified from existing databases of the pathological institute at our institution from January 2009 to November 2015.

Results: We identified 414 patients with GI-NENs, 250 cases were diagnosed as neuroendocrine tumor G1 (NET G1), 25 as neuroendocrine tumor G2 (NET G2), 53 as neuroendocrine tumor G3 (NET G3), 55 as neuroendocrine carcinoma G3 (NEC G3), and 31 as mixed adenoneuroendocrine carcinoma (MANEC); the overall survival (OS) rate at three years were 94.

[Characteristics of Clinicopathology and Genotype in 179 Cases with Gastrointestinal Stromal Tumor].

Objective: To analyze the characteristics of the clinicopathology and genotypes in patients with gastrointestinal stromal tumor (GIST).

Methods: The clinicopathological and genotypic data of 179 patients with GIST, who underwent treatment and genetic testing in the Hostital of West China from September 2009 to February 2009 were collected retrospectively.

Results: The tumor sites of the cases were located in stomach (88 cases, 49.
