A Novel Early Warning Model for Hand, Foot and Mouth Disease Prediction Based on a Graph Convolutional Network.

Objectives: Hand, foot and mouth disease (HFMD) is a widespread infectious disease that causes a significant disease burden on society. To achieve early intervention and to prevent outbreaks of disease, we propose a novel warning model that can accurately predict the incidence of HFMD.

Methods: We propose a spatial-temporal graph convolutional network (STGCN) that combines spatial factors for surrounding cities with historical incidence over a certain time period to predict the future occurrence of HFMD in Guangdong and Shandong between 2011 and 2019.

Silencing of miR-17-5p suppresses cell proliferation and promotes cell apoptosis by directly targeting PIK3R1 in laryngeal squamous cell carcinoma.

Background: Increasing evidence has suggested that microRNAs (miRNAs) act as key post-transcriptional regulators in tumor progression. Previous studies have confirmed that miR-17-5p functions as an oncogene in multiple cancers and contributes to tumor progression. However, the role and biological functions of miR-17-5p in the development of laryngeal squamous cell carcinoma (LSCC) still remain unknown.

Upregulation of ERp57 promotes clear cell renal cell carcinoma progression by initiating a STAT3/ILF3 feedback loop.

Background: ERp57 dysfunction has been shown to contribute to tumorigenesis in multiple malignances. However, the role of ERp57 in clear cell renal carcinoma (ccRCC) remains unclear.

Methods: Cell proliferation ability was measured by MTT and colony forming assays.

Correlation Between HLA-A, B and DRB1 Alleles and Severe Fever with Thrombocytopenia Syndrome.

Objective: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging hemorrhagic fever caused by a tick-borne bunyavirus (SFTSV) in East Asian countries. The role of human leukocyte antigen (HLA) in resistance and susceptibility to SFTSV is not known. We investigated the correlation of HLA locus A, B and DRB1 alleles with the occurrence of SFTS.

Seroprevalence of Enterovirus A71 and Coxsackievirus A16 in Healthy People in Shandong Province, China.

Background: Hand, foot, and mouth disease has become very common in mainland of China in recent years, and enterovirus A71 and coxsackievirus A16 are its major etiologic factors. Here we investigated the seroprevalence of enterovirus A71 and coxsackievirus A16 based on a large group of healthy individuals in Shandong province, China.

Methods: A total of 1378 healthy individuals were tested for serum neutralizing antibodies against enterovirus A71 and coxsackievirus A16 using a micro neutralization test.

Buckwheat Rutin Inhibits AngII-induced Cardiomyocyte Hypertrophy via Blockade of CaN-dependent Signal Pathway.

Buckwheat rutin has been found to be able to inhibit angiotensin II (AngII) - induced hypertrophy in cultured neonatal rat cardiomyocytes, but the mechanism remains uncertain. In this study, myocardial hypertrophy model was made by adding AngII to the medium of cardiac myocytes of neonatal rats; meanwhile, different concentrations of buckwheat rutin were applied to observe their effects. Intracellular Ca(2+) level was detected by Hitachi - 850 fluorospectrophotometer, calcineurin (CaN) activity was measured by colorimetric method, the expression of CaN protein was observed with immunocytochemistry, and the proto - oncogene c - fos mRNA expression was assessed with reverse transcription polymerase chain reaction (RT - PCR).

[Analysis of clinical features and early warning indicators of death from hand, foot and mouth disease in Shandong province].

Objective: To understand the clinical features of death from hand, foot and mouth disease (HFMD) and to explore the early warning index of HFMD death.

Methods: A total of 41 HFMD death cases were collected as case group in Shandong province between 2009 and 2011, and another 123 serious HFMD cases were selected as control group according to the similar gender, place of origin and hospital level, with the ratio at 1:3. We investigated the general situation, clinical treatment, past medical history, clinical symptoms and signs of the ill children, and applied the conditional logistic regression to explore early warning index of HFMD death.

An anionic exchange stir rod sorptive extraction based on monolithic material for the extraction of non-steroidal anti-inflammatory drugs in environmental aqueous samples.

In this study, a stir rod sorptive extraction (SRSE) adsorbent material was prepared by coating poly(4-vinylpyridine-co-ethylene glycol dimethacrylate) [poly(VP-co-EDMA)] monolithic polymer on stir rod, and then applied to the extraction of three non-steroidal anti-inflammatory drugs (NSAIDs) in environmental aqueous samples. The preparation conditions of monolithic material such as the amount of porogen and the ratio of functional monomer to cross-linker were investigated. To achieve the best extraction efficiency, several parameters, including pH value of sample solution, salt concentration in sample matrix, desorption solvent, extraction time, and desorption time, were optimized.

Determination of benzimidazole residues in edible animal food by polymer monolith microextraction combined with liquid chromatography-mass spectrometry.

A sensitive method has been developed for the simultaneous determination of 10 benzimidazole residues and some of their metabolites in egg, milk, chicken, and pork. This method is based on the combination of polymer monolith microextraction (PMME) technique with liquid chromatography and electrospray ionization mass spectrometry (LC-ESI/MS). The extraction was performed with a poly(methacrylic acid-co-ethylene glycol dimethacrylate) (MAA-co-EGDMA) monolithic capillary column.

[Construction and identification of bait recombinant vector of pGBKT7-tumor necrosis factor-alpha converting enzyme cytoplasmic tail in the yeast two-hybrid system].

Objective: To construct the bait vector pGBKT7-TACEc (cytoplasmic tail of tumor necrosis factor-alpha converting enzyme) of Macthmaker GAL4 Two-hybrid System 3, and to test whether it has self-activation and toxic action.

Methods: TACEc gene was amplified by RT-PCR from the mouse testis, and the EcoRI and BamHI sites were introduced into it. The TACEc gene, after sequenced, was cloned into pGBKT7.
