Predictive value of machine learning model based on CT values for urinary tract infection stones.

Preoperative diagnosis of infection stones presents a significant clinical challenge. We developed a machine learning model to predict urinary infection stones using computed tomography (CT) values, enabling preoperative identification. In this study, we included 1209 patients who underwent urinary lithotripsy at our hospital.

Hematoma evacuation based on active strategies versus conservative treatment in the management of moderate basal ganglia hemorrhage: A retrospective study.

Objective: The internal capsule of the basal ganglia is vulnerable to direct pressure from the hematoma and to secondary damage from toxic products of hemorrhage. Our study evaluated the risk and benefits of active strategies including ultra-early surgery and hematoma evacuation through a transsylvian-transinsular approach for moderate basal ganglia hemorrhage.

Methods: We retrospectively collected patients with moderate basal ganglia hemorrhage in two hospitals.

"Cutoff Clipping" Technique as a Tentative Clipping Alternative for Large Aneurysms: A Preliminary Study.

Background: Intraoperative rupture of an aneurysm is potentially devastating. The thin-walled regions (TIWRs) of an aneurysm are associated with rupture risk. This study aimed to describe the feasibility and concerns of the "cutoff clipping" technique for TIWRs disposition of certain complex aneurysms.

Systematic Microwave-Assisted Postsynthesis of Mn-Doped Cesium Lead Halide Perovskites with Improved Color-Tunable Luminescence and Stability.

The metal doping at the Pb position provides improved luminescence performance for the cesium lead halide perovskites, and their fabrication methods assisted by microwave have attracted considerable attention due to the advantages of fast heating and low energy consumption. However, the postsynthetic doping strategy of the metal-doped perovskites driven by microwave heating still lacks systematic research. In this study, the assembly of CsPbBr/CsPbBr with a strong fluorescence peak at 523 nm is used as the CsPbBr precursor, and through the optimization of the postsynthetic conditions such as reaction temperatures, Mn/Pb feeding ratios, and Mn sources, the optimum Mn-doped product (CsPb(Cl/Br):Mn) is achieved.

[Determination of fipronil and its metabolites in livestock and poultry liver by high performance liquid chromatography-tandem mass spectrometry with dispersive solid phase extraction].

The residues of fipronil and its metabolites, namely fipronil-desulfinyl, fipronil-sulfone, and fipronil-sulfide, have attracted increasing attention since the European egg contamination incident. In this study, by optimizing the pretreatment method and chromatographic conditions, a simple extraction method coupled with high performance liquid chromatography-tandem mass spectrometry was developed for the simultaneous determination of fipronil and its metabolites, including fipronil-desulfinyl, fipronil-sulfone, and fipronil-sulfide, in livestock and poultry liver. The optimal pretreatment method for fipronil and its metabolites was determined by comparing the recoveries obtained with different extraction solvents (methanol, acetonitrile, acetone, and ethyl acetate), and by purification with -propyl ethylenediamine (PSA) and octadecylsilane (C18).

Radar Emitter Recognition Based on the Energy Cumulant of Short Time Fourier Transform and Reinforced Deep Belief Network.

To cope with the complex electromagnetic environment and varied signal styles, a novel method based on the energy cumulant of short time Fourier transform and reinforced deep belief network is proposed to gain a higher correct recognition rate for radar emitter intra-pulse signals at a low signal-to-noise ratio. The energy cumulant of short time Fourier transform is attained by calculating the accumulations of each frequency sample value with the different time samples. Before this procedure, the time frequency distribution via short time Fourier transform is processed by base noise reduction.

The value of red cell distribution width in patients with ovarian cancer.

Background: The red cell distribution width (RDW) has attracted attention in the diagnosis of malignant tumors. In this study, we analyzed the correlation between the RDW and ovarian cancer by observing changes in the RDW in patients with ovarian cancer.

Methods: Patients diagnosed with ovarian cancer at the First Affiliated Hospital of Guangxi Medical University, China, from 2012 to 2016, were retrospectively analyzed.

Prevalence of diabetes and determinants: evidence from a minority region in People's Republic of China.

Background: This study aimed to examine the prevalence of diabetes mellitus and other categories of glucose intolerance (impaired glucose tolerance and impaired fasting glucose) and explore the risk factors in an ethnic minority region, Guangxi Zhuang Autonomous Region, People's Republic of China.

Methods: A population-based study enrolled 53,270 residents older than 5 years in Guangxi, People's Republic of China. The prevalence of diabetes was calculated using the 1999 World Health Organization (WHO) oral glucose tolerance test diagnostic criteria.

The Effect of HBV Genotype C on the Development of HCC Differs Between Wild-Type Viruses and Those With BCP Double Mutations (T(1762)A(1764)).

Background: Association of hepatitis B virus (HBV) genotype C with hepatocellular carcinoma (HCC) development remains controversial. HBV basal core promoter (BCP) double mutations (T(1762)A(1764)) are very strong confounding factors of genotypes B and C in HCC development.

Objectives: To investigate the association of HBV genotype C with HCC development after controlling for BCP double mutations.

[Validation of a Chinese version of the child perception questionnaire].

Objective: To translate the original English version of the child perception questionnaire (CPQ(11-14)) into Chinese version and to test the psychometric properties of the Chinese version in order to use among the Chinese children.

Methods: The original English version of CPQ(11-14) was translated into Chinese, and pre-tested and cross-cultural adapted. Subsequently, the Chinese version with a general questionnaire was administered to 218 children aged from 11 to 14, clinical data on caries status and malocclusion were collected through oral health examination.
