RESUMEN

To investigate the correlation between serum thyroid-stimulating hormone (TSH) levels and glycolipid metabolism in patients with polycystic ovary syndrome (PCOS). From January 2021 to November 2022, 105 patients with PCOS were selected for this retrospective study. All patients were administered drug-induced ovulation treatment and were divided into 2 groups according to ovulation status. There were 67 and 38 patients in the ovulation and non-ovulation groups, respectively. Venous blood (5 mL) was collected on the day after admission from the non-ovulation group and on the day of physical examination from the ovulation group. Several indicators were measured, including TSH, fasting plasma glucose (FPG), glycosylated hemoglobin, total cholesterol (TC), high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride (TG), albumin (ALB), prealbumin (PA), and transferrin (TF). Weight, BMI, waistline, and hipline in the non-ovulation group were significantly higher than those in the ovulation group (P < .05). There were no significant differences in glycosylated hemoglobin, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol levels between the non-ovulation and ovulation groups (P > .05). Compared with the ovulation group, the levels of TSH, FPG, TC, and TG in the non-ovulation group were significantly higher (P < .05). Serum ALB, PA, and TF the non-ovulation group were significantly higher than those in the ovulation group (P < .05). Correlation analysis showed that TSH was negatively correlated with weight, BMI, waistline, hipline, waist-hip ratio, FPG, ALB, PA, and TF in the non-ovulation group (P < .05) and had no significant correlation with TC and TG (P > .05). Our findings demonstrate TSH levels may be associated with weight, BMI, waistline, hipline, waist-hip ratio, FPG, ALB, PA, and TF in patients with PCOS.

RESUMEN

IFN-α receptor (IFNAR) is critical for maintaining the crosstalk between cancer cells and lymphocytes. We investigated IFNAR1 expression in peripheral blood CD4+ and CD8+ T cells and explored their relationships with plasma cytokines, chemosensitivity and infiltrated T cells in the tumor microenvironment (TME) of colorectal cancer (CRC). The levels of IFNAR1, IFN-γ, and PD1 in peripheral T cells were tested using flow cytometry. Immunohistochemical staining of IFNAR1 in CRC tissues was performed. A cytometric bead array was used to determine the plasma concentrations of cytokines. In CRC patients, IFNAR1 levels were significantly increased in peripheral blood T cells, and plasma IL-6 levels were also significantly increased. Pearson correlation analysis revealed that IFNAR1 expression in CD8+ T cells was negatively associated with plasma IL-2, IFN-γ, and TNFα. IFNAR1 expression in CD4+ T cells was positively associated with TME infiltrated levels of CD8+ T cells. The levels of CD8+ T cells with IFNAR1 and plasma IFN-γ were associated with chemosensitivity. Collectively, IFNAR1 levels in CD4+ and CD8+ T cells were significantly upregulated in CRC patients and positively associated with T-cell infiltration. IFNAR1 may be a chemotherapy biomarker for predicting response.

RESUMEN

Objective To investigate the standard prescription in patients with stable chronic obstructive pulmonary disease (COPD) and to provide a reference for rational drug use. Methods A total of 157 patients with COPD in our hospital were included into the study from June 2016 to January 2017. Of patients, there were 3 patients with mild airflow limitation, 18 patients with moderate airflow limitation, 39 patients with severe airflow limitation and 97 patients with extremely severe airflow limitation. The self-made questionnaire was used to understand the basic situation, complications and irrational drug use. Results Most severe and extremely severe COPD patients were male, and most of them combined with high blood pressure and cardiovascular disease. Of the 157 patients, 12 cases with moderate airflow limitation used inhaled therapy of corticosteroids/bronchodilator medications, 45 cases combined with pneumocardial disease used compound methoxyphenamine, 26 cases used leukotriene receptor antagonist, 14 cases used antibiotics for no obvious infection symptom and 11 cases used systemic corticosteroids in stable COPD. All of them belong to rational drug use. Conclusion There are some unreasonable situations of drug using in patients with stable COPD. The medical staff should strictly control indications, strengthen the education for drug use, guide rational drug use and avoid the occurrence of adverse consequences.

RESUMEN

Colloidal perovskite oxide nanocrystals have attracted a great deal of interest owing to the ability to tune physical properties by virtue of the nanoscale, and generate thin film structures under mild chemical conditions, relying on self-assembly or heterogeneous mixing. This is particularly true for ferroelectric/dielectric perovskite oxide materials, for which device applications cover piezoelectrics, MEMs, memory, gate dielectrics and energy storage. The synthesis of complex oxide nanocrystals, however, continues to present issues pertaining to quality, yield, % crystallinity, purity and may also suffer from tedious separation and purification processes, which are disadvantageous to scaling production. We report a simple, green and scalable "self-collection" growth method that produces uniform and aggregate-free colloidal perovskite oxide nanocrystals including BaTiO3 (BT), Ba(x)Sr(1-x)TiO3 (BST) and quaternary oxide BaSrTiHfO3 (BSTH) in high crystallinity and high purity. The synthesis approach is solution processed, based on the sol-gel transformation of metal alkoxides in alcohol solvents with controlled or stoichiometric amounts of water and in the stark absence of surfactants and stabilizers, providing pure colloidal nanocrystals in a remarkably low temperature range (15 °C-55 °C). Under a static condition, the nanoscale hydrolysis of the metal alkoxides accomplishes a complete transformation to fully crystallized single domain perovskite nanocrystals with a passivated surface layer of hydroxyl/alkyl groups, such that the as-synthesized nanocrystals can exist in the form of super-stable and transparent sol, or self-accumulate to form a highly crystalline solid gel monolith of nearly 100% yield for easy separation/purification. The process produces high purity ligand-free nanocrystals excellent dispersibility in polar solvents, with no impurity remaining in the mother solution other than trace alcohol byproducts (such as isopropanol). The afforded stable and transparent suspension/solution can be treated as inks, suitable for printing or spin/spray coating, demonstrating great capabilities of this process for fabrication of high performance dielectric thin films. The simple "self-collection" strategy can be described as green and scalable due to the simplified procedure from synthesis to separation/purification, minimum waste generation, and near room temperature crystallization of nanocrystal products with tunable sizes in extremely high yield and high purity.

RESUMEN

The degrading regulations of combined pollutants of chlorfenvinfos and fenthion in red soil were studied, in which soil incubation, gas chromatography with nitrogen-phosphorus detection for analysis are utilized. The main conclusions drawn are as follows: under combined pollution condition, the degrading amount of fenthion was significantly higher than that of fenthion alone in soil; under saturated soil humidity, the degrading amount of fenthion was less changed, while that of chlorfenvinfos was increased by 33.3% - 1250%. Soil drought made degradation amount of fenthion decreased a little, while made chlorfenvinfos increased significantly prior to the 21st day after addition of pesticide; nitrogen fertilizer application stimulated both fenthion and chlorfenvinfos degraded; the chemical degrading amount of fenthion in soil with organic matter eliminated was decreased by 22.4% - 30.8%, while that of chlorfenvinfos was increased 42.1% - 2370% at the earlier stage, and was decreased 11% - 17.3% at the later stage. Therefore, there are differences of degrading regulation between single pesticide pollutant and combined pesticide pollutants in soil, and the degradation of organophosphorus pesticides in combined pollutants are influenced with each other.
