[Therapeutic effect of Actovegin on acute oral mucositis caused by radiotherapy].

PURPOSE： To explore the clinical effect of Actovegin in the treatment of acute oral mucositis in patients with radiotherapy. METHODS： One hundred and thirteen patients with acute oral mucositis caused by radiotherapy for nasopharyngeal carcinoma admitted to the Department of Oncology, the Fifth People's Hospital of Qinghai Province from July 2015 to September 2017 were randomly divided into the experimental group (57 cases) and control group (56 cases). Patients in the experimental group were treated with Aiweizhi, while patients in the control group were treated with new rehabilitation.

[Effects of different orthodontic treatments on sputum chemokines CX3CL1, RANKL/OPG levels in patients with malocclusion].

Purpose: To investigate the effects of different orthodontic treatments on gingival crevicular fluid chemokine CX3CL1, nuclear factor κB receptor activating factor ligand/osteoprotegerin(RANKL/OPG) levels in patients with malocclusion.

Methods: Ninety-six patients with malocclusion who were scheduled to undergo orthodontic treatment were randomly divided into four groups. All patients were treated with square wire appliance, and 0, 50, 150, 250 g of far-distal orthodontic force were given respectively.

Serum uric acid is an independent predictor of renal outcomes in patients with idiopathic membranous nephropathy.

Purpose: Accumulating evidence suggests that a relationship exists between serum uric acid (UA) and the progression of chronic kidney disease (CKD), but information regarding idiopathic membranous nephropathy (IMN) is limited.

Methods: Patients with renal biopsy-confirmed diagnosis of IMN between 2009 and 2017 were identified. The demographic and clinical data recorded at the time of renal biopsy were considered the baseline values.

Serum C3/C4 ratio is a novel predictor of renal prognosis in patients with IgA nephropathy: a retrospective study.

IgA nephropathy (IgAN) is an autoimmune disease associated with complement activation. It is unclear whether the ratio of serum C3 and C4 concentrations (C3/C4 ratio) can predict renal outcomes in IgAN patients. A total of 1503 patients diagnosed with IgAN via renal biopsy were recorded in this study.

Peptide-Conjugated Quantum Dots Act as the Target Marker for Human Pancreatic Carcinoma Cells.

Background/aims: In the present study, we describe a novel and straightforward approach to produce a cyclic- arginine-glycine-aspartic (RGD)-peptide-conjugated quantum dot (QD) probe as an ideal target tumor biomarker. Due to its specific structure, the probe can be used for targeted imaging of pancreatic carcinoma cells.

Methods: Pancreatic carcinoma cells were routinely cultured and marked with QD-RGD probe.

Mycoplasma penetrans infection is a potential cause of immunoglobulin A nephropathy: a new animal model.

Aim: A new animal model of immunoglobulin A nephropathy (IgAN) was made by infecting mice with Mycoplasma penetrans (Mpe). To examine the pathogenesis of IgAN induced by Mpe infection, tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and nuclear factor-kB (NF-kB) protein levels were compared among study groups.

Methods: To make an experimental IgAN animal model, mice were infected with Mpe, SP-4 medium or phosphate-buffered saline (PBS) via the urinary tract.

Classification of gastric pit patterns by confocal endomicroscopy.

Background: Confocal endomicroscopy is a newly developed endoscopic imaging technology that produces 1000-fold magnification cross-sectional images of the GI surface and subsurface tissue during routine endoscopy. The gastric pit patterns identified by confocal endomicroscopy and correlation with histopathologic examination have not yet been established.

Objective: Our purpose was to explore the appearance of various kinds of gastric pits and clarify the relationship between gastric pit patterns and the histopathologic findings.

[Confocal endomicroscopy for differential diagnosis of indented gastric lesions].

Objective: Confocal endomicroscope (CEM) is a newly developed endoscope based on the integration of a confocal laser scanning microscope at the distal tip of a conventional video endoscope. It can visualize living tissue at a cellular level. The aim of the present study was to assess the value of CEM for prediction of the histopathology of gastric depressed-type lesions during endoscopy.

Confocal endomicroscopy for in vivo detection of microvascular architecture in normal and malignant lesions of upper gastrointestinal tract.

Background And Aim: Confocal laser endomicroscopy allows subsurface analysis of gastrointestinal mucosa during ongoing endoscopy. The present study assessed the feasibility of in vivo detecting superficial vascular architecture by confocal endomicroscopy in normal upper gastrointestinal mucosa and malignant lesions.

Methods: Early gastric cancer in eight patients, superficial esophageal carcinoma in six patients, and asymptomatic normal control in 10 patients were studied by confocal endomicroscopy.

[Non-parameter estimation algorithm to determine stellar effective temperature].

The effective temperature of a star is one of the most important parameters, which determine the continuum and spectral lines in the stellar spectrum. A non-parameter estimation algorithm is proposed to estimate the stellar effective temperature in the present paper. Firstly, the spectrum data is processed by principal component analysis(PCA), then, an estimating model based on a Gaussian kernel function is set up using the PCA data and their temperatures.
