Development of the self-management scale for urolithiasis patients with indwelling double-J tube.

Purpose: To develop a specific self-management scale applicable to patients with indwelling double-J tube in urolithiasis, and to test its reliability and validity.

Methods: The construction and validation of our scale involved three stages. First, an initial version of the questionnaire was formed through literature analysis, group discussions, semi-structured interviews, and the Delphi method.

Neoadjuvant chemotherapy combined with laparoscopic cytoreductive surgery in patients with advanced ovarian cancer.

Purpose: To explore the clinical efficacy and safety of neoadjuvant chemotherapy (NACT) combined with minimally invasive laparoscopic cytoreductive surgery in the treatment of patients with advanced ovarian cancer (AOC).

Methods: The clinical data of 116 patients with AOC were divided into NACT group (NACT combined with laparoscopic cytoreductive surgery, n=58) and control group (cytoreductive surgery alone, n=58). The short-term efficacy, surgery-related indexes, incidence of adverse reactions, and changes in levels of serum human epididymis protein 4 (HE4), vascular endothelial growth factor (VEGF) and carbohydrate antigen 125 (CA125) before and after treatment were compared between the two groups.

Foxc2 and BMP2 Induce Osteogenic/Odontogenic Differentiation and Mineralization of Human Stem Cells from Apical Papilla.

As a transcription factor regulated by bone morphogenetic protein 2 (BMP2), Forkhead c2 (Foxc2) plays a pivot role in osteogenesis/odontogenesis. However, the role of Foxc2 and BMP2 in regulating osteo-/odontogenic differentiation and mineralization of stem cells from apical papilla (SCAP) is still uncertain. In this research, overexpression of Foxc2 gene significantly improved the proliferation of SCAP four days and eight days after transfection, but overexpression of both Foxc2 and BMP2 genes significantly inhibited the proliferation of SCAP eight days after transfection.

[Imaging analysis of jaw defects reparation with antigen-extracted porcine cancellous bone].

At present, most of the bone xenograft for clinical application comes from bovine. In recent years, many studies have been done on the clinical application of porcine xenograft bone. The goal of this study was to evaluate the effect of canine mandibular defects reparation with antigen-extracted porcine cancellous bone by imaging examination.

Treatment evaluation of Wharton's jelly-derived mesenchymal stem cells using a chronic salpingitis model: an animal experiment.

Background: The present study was conducted to evaluate new methods to repair the reproductive function of the oviduct, thereby allowing gametes to combine and grow in vivo under natural circumstances.

Methods: Sixty pathogen-free female New Zealand rabbits were divided into three groups: a wild-type group, an untreated control group, and a treatment group. Disposable sterile newborn sputum suction tubes were inserted into the urogenital tract to instill an Escherichia coli suspension into the uterine cavity to establish the chronic salpingitis model.

[Effect of Electroacupuncture Combined with Rehabilitation Training on Neurological Function and Expression of Neuronal Growth Associated Protein 43 and Synaptophysin in Rats with Focal Cerebral Ischemia/Reperfusion Injury].

Objective: To observe the effect of electroacupuncture (EA) combined with rehabilitation training on motor function and expression of neuronal growth associated protein 43 (GAP-43) and synaptophysin (SYP) in hippocampal CA 3 region in rats with focal cerebral ischemia/reperfusion injury (CI/RI).

Methods: A total of 46 SD rats were randomized into normal control, CI/RI model, rehabilitation training (RT), paralysis-side (unilateral)-EA+RT, and bilateral-EA+RT groups (=6 in the normal control group, and =10 in each of the other group). The CI/RI model was established by occlusion of the middle cerebral artery (MCAO) and reperfusion.

The effect of graded glass-zirconia structure on the bond between core and veneer in layered zirconia restorations.

Objective: The aim of this study was to test the hypothesis that a graded glass-zirconia structure can strengthen the core-veneer bond in layered zirconia materials.

Methods: A graded glass-zirconia structure was fabricated by infiltrating glass compositions developed in our laboratory into a presintered yttria tetrahedral zirconia polycrystal (Y-TZP) substrate by the action of capillary forces. The wettability of the infiltrated glass and Y-TZP substrate was investigated by the sessile drop technique.

The influence of maternal islet beta-cell autoantibodies in conjunction with gestational hyperglycemia on neonatal outcomes.

Objective: To determine the predictive value of the presence of maternal islet beta-cell autoantibodies with respect to neonatal outcomes.

Methods: A total of 311 pregnant women with abnormal 75 g oral glucose tolerance test (OGTT) results were enrolled in this study. Maternal glutamic acid decarboxylase autoantibodies (GADA), islet cell autoantibodies (ICA) and insulin autoantibodies (IAA) were tested in fasting blood both on the day following the routine OGTT and before delivery.

Potential proinflammatory and osteogenic effects of dicalcium silicate particles in vitro.

Background: Due to their biocompatibility and bioactivity, dicalcium silicate (C2S) and hydroxyapatite (HA) are used as coating materials for prosthetic orthopedic and dental implants or as bone substitute materials to fill bone defects. However, prostheses and bone substitutes can release particles that trigger an immune response in the recipient. The immunological effects of C2S particles have not yet been studied.

Valuable radiographic tool for odontogenic jaw keratocyst diagnosis and surgical planning.

Objective: To investigate the clinical use of cone beam computed tomography in the diagnosis of odontogenic jaw keratocyst and to guide computer-aided surgical treatment planning.

Methods: Imaging, image processing, and visualization technologies were used to produce clear diagnosis, provide proper treatment, and formulate favourable prognosis. Cone beam computed tomography was used to collect medical information including site, extent, shape, and other characteristic features of a patient with large odontogenic jaw keratocyst.

Influence of mesoporous silica coating treatment on push-out bond strength of zirconia posts.

This study aimed to evaluate the influence of mesoporous silica coating surface treatments on push-out bond strength of zirconia posts. Zirconia posts (Cosmopost) were treated with vehicle (control), sandblasting plus silane application (SB+SI), a combination of sandblasting, mesoporous silica coating and silane application (SB+MSC+SI) (n=10/group). Specimens were cemented with RelyX Unicem (3M ESPE, Germany) then horizontally segmented into three sections and subjected to a push-out test.

An in vitro evaluation of the zirconia surface treatment by mesoporous zirconia coating on its bonding to resin cement.

The effect of zirconia surface treatment by mesoporous zirconia coating on the microtensile bond strength (MTBS) between zirconia and resin cement was investigated in this work. 160 zirconia specimens were prepared and divided into four groups according to surface treatments: (1) airborne-particle-abrasion treatment (APA); (2) glass infiltration and hydrofluoric acid treatment (GI+HF); (3) mesoporous zirconia coating (MZ); and (4) no treatment (C). The as-prepared zirconia specimens were bonded using Panavia F2.
