[Effect of oral motor intervention in improving brain function development in preterm infants: a randomized controlled trial].

Objective: To study the effect of oral motor intervention (OMI) on brain function development in preterm infants.

Methods: A total of 112 preterm infants were stratified into small-gestational-age (30-31 weeks) and large-gestational-age (32-33 weeks) according to gestational age at birth. The preterm infants were randomly divided into a control group and an intervention group, with 56 infants in each group.

Resveratrol suppresses hyperoxia-induced nucleocytoplasmic shuttling of SIRT1 and ROS production in PBMC from preterm infants in vitro.

Objective: By assessing silent mating-type information regulation 2 homolog 1 (SIRT1) nucleocytoplasmic shuttling and reactive oxygen species (ROS) levels in peripheral blood mononuclear cells (PBMCs), this study aimed to explore the role of SIRT1 in premature infants after exposure to hyperoxia and assess the protective effects of resveratrol (Res).

Methods: Firstly, ROS levels as well as SIRT1 translocation and expression in PBMCs samples were evaluated from 40 premature infants with different oxygen amounts received at birth. Then, PBMCs, from additional 40 premature infants administered no oxygen at birth, were used to establish an in vitro model of hyperoxia.

[Resveratrol increases sirtuin 1 expression in peripheral blood mononuclear cells of premature infants and inhibits the oxidative stress induced by hyperoxia in vivo].

Objective: To explore the effect of resveratrol on the levels of sirtuin 1 (SIRT1) and reactive oxygen species (ROS) in peripheral blood mononuclear cells (PBMCs) of premature infants exposed to hyperoxia.

Methods: Peripheral blood and isolated PBMCs from premature infants (gestational age<32 weeks) without oxygen supplement were collected and were randomly assigned into four groups: control, air+resveratrol, hyperoxia, and hyperoxia+resveratrol. The PBMCs were cultured in vitro for 48 hours, then the ROS content in PBMCs was measured by laser scanning confocal microscopy.

Coexpression of MYC and BCL-2 predicts prognosis in primary gastrointestinal diffuse large B-cell lymphoma.

Aim: To investigate whether MYC and BCL-2 coexpression has prognostic significance in primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL) patients, and explore its associations with patients' clinical parameters.

Methods: Fresh and paraffin-embedded tumor tissue samples from 60 PGI-DLBCL patients who had undergone surgery at the Tianjin Medical University Cancer Institute and Hospital from January 2005 to May 2010 were obtained, and 30 lymphoid tissue samples from reactive lymph nodes of age- and sex-matched patients represented control samples. Staging and diagnostic procedures were conducted according to the Lugano staging system.

A retrospective analysis of the clinicopathological characteristics of large cell carcinoma of the lung.

The aim of the present study was to analyze and summarize the clinicopathological characteristics of large-cell lung carcinoma (LCLC) of the lung, in order to improve the definite diagnosis rate of LCLC. Clinicopathological data of 174 patients with LCLC, confirmed pathologically, were retrospectively reviewed. The 174 cases of LCLC accounted for 5.

Prognostic factors associated with solitary plasmacytoma.

Solitary plasmacytoma (SP) is a rare tumor with low incidence. The aim of this study was to investigate the clinical features, treatment strategies, and relative prognostic factors of 66 patients with SP. These patients made up 10.

[Differentiation of subtypes of renal cell carcinoma by double-phase helical computed tomography].

Objective: To evaluate the imaging features of different subtypes of renal cell carcinoma (RCC) by double-phase helical computed tomography (CT) and to enhance its pre-operative diagnosis level.

Methods: A total of 460 RCC were reviewed retrospectively. Tumor size, enhancement degree, enhancement drop between corticomedullary (CMP), nephrographic (NP), enhancement pattern, and tumor density (homogeneity, degeneration or necrosis, calcification) were observed respectively.

[Imaging features of nonepithelial tumors of the bladder].

Objective: To summarize the imaging features of nonepithelial tumors of the bladder.

Methods: The Imaging findings in 20 surgically treated patients with pathologically proved nonepithelial tumors of the bladder were retrospectively analyzed. The tumors included leiomyoma (n = 9), pheochromocytoma (n = 6), leiomyosarcoma (n = 2), rhabdomyosarcoma (n = 1), carcinosarcoma (n = 1), inflammatory myofibroblastoma (n = 1).
