Comparison of outcomes between single- and multiple-perforator-based free perforator flaps: A systematic review and meta-analysis.

Background: Perforator-based free perforator flaps have become an important tool for the reconstruction of tissue defects. The effect of the number of perforators on the outcomes of perforator flaps has been widely debated. This study aimed to compare the outcomes of single- and multiple-perforator-based free perforator flaps in free-flap reconstruction.

Risk Factors for Free Flap Outcomes: A Retrospective Study of 318 Free Flaps for Head and Neck Defect Reconstruction.

Objectives: This study was conducted to identify the risk factors for free flap outcomes in head and neck reconstruction.

Methods: A retrospective review of 318 free flaps were used for head and neck reconstructions in 317 patients over seven years. The patient characteristics, surgical data, and flap outcomes were recorded.

Comparing donor site morbidity between radial and ulnar forearm free flaps: a meta-analysis.

The vascularised forearm free flap is a workhorse flap for the reconstruction of many types of soft tissue defects. However, the difference in donor-site morbidity between the radial forearm free flap (RFFF) and ulnar forearm free flap (UFFF) remains controversial. This study aimed to compare the donor-site outcomes of RFFF and UFFF.

The effectiveness and harms of bortezomib in combination with chemotherapy for mantle cell lymphoma: A protocol for systematic review and meta-analysis.

Background: Chemotherapy with or without consolidation followed by autologous hematopoietic stem cell transplantation is the first-line treatment for mantle cell lymphoma. However, the effectiveness and safety of bortezomib-based chemotherapy for patients with mantle cell lymphoma is still uncertain.

Methods: In this systematic review, the electronic databases of Cochrane Central Register of Controlled Trials, EMBASE, and PUBMED will be searched from inception to May 1, 2020.

MicroRNA‑21 serves an important role during PAOO‑facilitated orthodontic tooth movement.

Periodontal accelerate osteogenesis orthodontics (PAOO) is an extension of described techniques that surgically alter the alveolar bone; however, the specific mechanism underlying the technique is not completely understood. The aim of the present study was to evaluate the roles of microRNA (miR)‑21 during PAOO. Sprague‑Dawley rats were divided into the following four groups: i) Group tooth movement (TM), underwent TM and were administered normal saline (NS); ii) Group PAOO, underwent PAOO + TM and were administered NS; iii) Group agomiR‑21, underwent PAOO + TM and were administered agomiR‑21; and iv) Group antagomiR‑21, underwent PAOO + TM and were administered antagomiR‑21.

MicroRNA-532-3p Suppresses Malignant Behaviors of Tongue Squamous Cell Carcinoma Regulating CCR7.

To provide better therapeutic avenues for treating tongue squamous cell carcinoma (TSCC), a series of experiments about the effects of microRNA (miR)-532-3p on TSCC malignant behaviors were carried out. The result showed that miR-532-3p was down-regulated and C-C chemokine receptor 7 (CCR7) was up-regulated in the tumor tissues compared with those in the paired paratumor tissues. Further, expression of miR-532-3p was detected in four TSCC cell lines, TSCCA, TCA8113, CAL-27, and SCC-25.

Association between polymorphism of TGFA Taq I and cleft lip and/or palate: a meta-analysis.

Background: Cleft lip and palate (CL/P) is one of the most common malformations in humans. Transforming growth factor alpha (TGFA) is a well characterized mammalian growth factor which might contribute to the development of CL/P. This meta-analysis aimed to summarize the association between the TGFA Taq I polymorphisms and CL/P.

C392T polymorphism of the Wnt10a gene in non-syndromic oral cleft in a northeastern Chinese population.

Non-syndromic oral cleft is one of the most common congenital malformations, and more than 40 genes may be involved in its aetiology. Recent studies have shown that the Wnt10a gene may also contribute. We recruited 198 patients with non-syndromic oral clefts, comprising 96 elementary families (restricted to the patients and their parents) and 187 controls, to investigate their associations with the risk of such clefts and their subgroups in a Chinese Han population.

Accelerated OH(-) transport in activated carbon air cathode by modification of quaternary ammonium for microbial fuel cells.

Activated carbon (AC) is a promising catalyst for the air cathode of microbial fuel cells (MFCs) because of its high performance and low cost. To increase the performance of AC air cathodes, the acceleration of OH(-) transport is one of the most important methods, but it has not been widely investigated. Here we added quaternary ammonium to ACs by in situ anchoring of a quaternary ammonium/epoxide-reacting compound (QAE) or ex situ mixing with anion exchange resins in order to modify ACs from not only the external surface but also inside the pores.

Down-regulation of Wnt10a by RNA interference inhibits proliferation and promotes apoptosis in mouse embryonic palatal mesenchymal cells through Wnt/β-catenin signaling pathway.

Cleft palate is one of the most common birth defects. Both environmental and genetic factors are involved in this disorder. Here, we investigated the function of Wnt10a in proliferation and apoptosis of mouse embryonic palatal mesenchymal (MEPM) cells.

Rapid analysis of piperazine ferulate tablets by optic-fiber sensing technology and the similarity of ultraviolet spectra.

A rapid analysis method of piperazine ferulate tablets by optic-fiber sensing technology with UV-vis absorption spectrum was established. Qualitative and quantitative data were obtained and compared by maximum and minimum wavelength, absorbance and contrast spectra. Similarity method was used to identify authenticity of drugs.

[A three-dimensional finite element analysis for the biomechanical characteristics of orthodontic anchorage micro-implant].

Purpose: To establish a three-dimensional finite element model for orthodontic anchorage micro-implant,and to analyze the influence of different titled angles on the biomechanical characteristics of orthodontic anchorage implant-bone interface.

Methods: ANSYS(Analysis System)finite element analysis software was used to perform the finite element modeling of the micro-implant with 7 different tilted angles, including 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees and 90 degrees. A simulated orthodontic force, which was 200 grams, was loaded mesiodistally to the mathematical models.
