Using GIS technology, this study investigated the spatiotemporal distribution pattern of influenza incidence in Xinjiang from 2014 to 2023 based on influenza surveillance data. The study revealed a noticeable fluctuation trend in influenza incidence rates in Xinjiang, particularly notable spikes observed in 2019 and 2023. The results of the 3-year moving average showed a significant long-term upward trend in influenza incidence rates, confirmed by Theil-Sen method (MAD = 2.

Background: Different prostate cancer patients take different amounts of time to progress to castration-resistant prostate cancer (CRPC), and this difference in time determines the patient's ultimate survival time. If the time to progression to CRPC can be estimated for each patient, the treatment can be better individualized.

Objective: Castration-resistant prostate cancer is a challenge in attacking prostate cancer, the aim of the paper is to analyze the correlation between lactate dehydrogenase (LDH) and CRPC occurrence based on the restricted cubic spline model, and to provide a theoretical basis for LDH as a prognostic biomarker for prostate cancer patients.

With the ever-evolving cannabis industry, low-cost and high-throughput analytical methods for cannabinoids are urgently needed. Normally, (potentially) psychoactive cannabinoids, typically represented by Δ9-tetrahydrocannabinol (Δ9-THC), and nonpsychoactive cannabinoids with therapeutic benefits, typically represented by cannabidiol (CBD), are the target analytes. Structurally, the former (tetrahydrocannabinolic acid (THCA), cannabinol (CBN), and THC) have one olefinic double bond and the latter (cannabidiolic acid (CBDA), cannabigerol (CBG), and CBD) have two, which results in different affinities toward Ag(I) ions.

Background: Gene-environment interaction is related to the prevalence of hypertension, but the impact of genetic polymorphisms on hypertension may vary due to different geography and population.

Objective: To explore the impact of the interaction among occupational stress and MTHFR gene and SELE gene polymorphism on the prevalence of hypertension in Xinjiang oil workers.

Methods: A case-control study was conducted on 310 oil workers.

Objective: To investigate the effect of sleep disorders on hypertension in oil workers and its mediating effect analysis.

Methods: Between June and September 2019, 1420 workers aged 20-60 years(745 males and 675 females; 384 aged 30 years, 563 aged 30-45 years and 473 aged 45 years) from six oilfield bases in Karamay City, Xinjiang Uygur Autonomous Region were surveyed using a two-stage randomized whole-group sampling method. Their current conditions, and the information on gender, age, ethnicity, personal monthly income, education level, job title, smoking, alcohol consumption, height, weight, and shift work of the oil workers were investigated by the basic questionnaire.

Objective: The aim of this study is to explore sleep status and hypertension among oil workers in Xinjiang, China. It may provide new ideas and basis for the precise prevention and treatment of hypertension in occupational population.

Methods: Sleep status and hypertension were investigated in 3,040 workers by a multi-stage cluster sampling method in six oil field bases in Karamay City, Xinjiang.

The photodegradation of methyl orange in water by the catalyst TiO or the oxidants (HO, KIO) or their combination (TiO + HO, TiO + KIO) under UV light illumination is studied. During the above process, as far as the photodiscoloration degree of methyl orange is concerned, the effect sequence is KIO + TiO >> KIO > TiO + HO > TiO > HO; as far as the photomineralization degree of methyl orange is concerned, the effect sequence is TiO ≈ TiO + HO > HO > KIO + TiO >> KIO; as for the catalysis of TiO, h plays more important role than HO, the inorganic ions ([Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text]) are generated, especially for the amount of [Formula: see text]. Active HO is generated, we can measure HO by terephthalic acid (TA) indirectly: TA reacts with HO to form highly fluorescent product, namely 2-hydroxyterephthalic acid (TAOH).

Background: High-sensitivity C-reactive protein (hs-CRP) is not only a marker of inflammation but also a prognostic factor for ischemic stroke. The objective of our study was to investigative the association between hs-CRP levels and outcomes of patients with small-artery occlusion (SAO).

Methods: We selected 718 participants diagnosed with SAO (according to Trial of Org 10172 in Acute Stroke Treatment classification) using the stroke registry of the Department of Neurorehabilitation of Tianjin HuanHu Hospital.

PbMoO4 and PbWO4 are prepared by the simple precipitation method in this work, they show the photocatalytic activities for the degradation of methyl orange in water under the UV light illumination. In the above photocatalytic degradation processes, methyl orange concentration decreases quickly, the total organic carbon (TOC) decreases slowly; inorganic ions (SO4(2-), NO3(-), NO2(-), NH4(+)) can be formed and measured by the ion chromatograph; the pH value in the systems decreases gradually; a small quantity of HO˙(-)·can be generated and measured by the terephthalic acid (TA) indirectly. In order to estimate the roles of active species during the above photocatalytic degradation processes, isopropanol, (NH4)2C2O4, and 1,4-benzoquinone as the scavengers for HO˙, h(+), O2˙(-) are introduced into the systems, respectively.
