Effect of Butylphthalide soft capsules on cognitive function and dementia-related factors in elderly patients with Parkinson's disease dementia during the COVID-19 pandemic.

Objective: To observe the effect of Butylphthalide soft capsules on improving cognitive function, activity of daily living, and dementia-related factors of elderly patients with Parkinson's disease dementia (PDD) during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: The clinical data of 126 elderly patients with PDD admitted to the Second Affiliated Hospital of Zhengzhou University during the COVID-19 pandemic were analyzed retrospectively. Patients were assigned to a control group (conventional clinical treatment, n=50) and a research group (conventional clinical treatment combined with Butylphthalide soft capsules, n=76).

Curcumin prevents Alzheimer's disease progression by upregulating JMJD3.

The main purpose of this research was to explore the molecular mechanisms of Jumonji Domain-Containing Protein 3 (JMJD3) in Alzheimer's disease (AD) and to analyze its role in the anti-AD mechanism of curcumin (CUR). In the study of AD, JMJD3 overexpression promoted the trimethylation of histone H3 lysine 27 (H3K27me3), downregulated brain-derived neurotrophic factor (BDNF ), improved the abnormality of mitochondrial stress response (MSR) markers, Aβ accumulation, increased cell proliferation and inhibited apoptosis. Upregulating BDNF also achieved above similar results.

Curcumin slows the progression of Alzheimer's disease by modulating mitochondrial stress responses via JMJD3-H3K27me3-BDNF axis.

Disturbance of mitochondrial proteins by amyloid beta-protein (Aβ) that associates with mitochondrial stress responses (MSR) is one of the pathological mechanisms of Alzheimer's disease (AD). This study tried to explore whether the axis of Jumonji domain-containing protein 3 (JMJD3)-trimethylated lysine 27 on histone H3 (H3K27me3)-brain derived neurotrophic factor (BDNF) is involved in the regulation of MSR which in turn intervenes in the process of AD, and whether curcumin (CUR) has a protective role against AD by influencing this axis, aiming to provide insights into AD treatment. AD mouse models presented a significant aggregation of Aβ, with conspicuous pathological changes in brain tissues and an increase in neuronal apoptosis.

The epigenetic silencing of microRNA-433 facilitates the malignant phenotypes of non-small cell lung cancer by targeting CREB1.

Objective: MicroRNAs (miRNAs) play a big role in the regulation of non-small cell lung cancer (NSCLC) development. The objective of this study is to determine how DNA methylation regulates miR-433 in NSCLC.

Methods: The degree of DNA methylation was determined, and the relevance of miR-433 and the features of NSCLC patients were assessed.

Noncoding RNAs: emerging players in skin cancers pathogenesis.

Skin malignancies form in tissues of the skin and are the most frequent cancers in the world, with an increasing incidence and a steady fatality rate. They are classified as melanoma or nonmelanoma cancers, which include basal cell carcinoma and squamous cell carcinoma. Noncoding RNA transcripts have received increased attention after the thorough analysis of the human genome revealed that most of the genomic components are not encoded to protein.

Knocking down LINC01116 can inhibit the regulation of TGF-β through miR-774-5p axis and inhibit the occurrence and development of glioma.

Background: Many studies have shown that non-coding RNAs (ncRNAs), including long non-coding RNA (LncRNA) and micro RNA (miRNA), play a crucial regulatory role in glioma. LINC01116 is a newly discovered LncRNA, and the relationship between LncRNA and glioma is still under exploration.

Method: LncRNAs with potential differences were screened through GEO database, and the expressions of LINC01116 and miR-744-5p/TGF-β1 in glioma tissues were tested using qRT-PCR.

Comprehensive analysis of core genes and key pathways in Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative disease that occurs mostly in middle-aged and older adults. Its main pathological feature is the progressive death of substantia nigra dopaminergic neurons. As the world's population ages, the number of PD patients is increasing.

Long noncoding RNA CASC15 predicts unfavorable prognosis and exerts oncogenic functions in non-small cell lung cancer.

Background: Aberrant expression of long non-coding RNA cancer susceptibility 15 (lncRNA CASC15) has been documented in various human tumors, and upregulation of CASC15 is closely correlated with cancer progression. However, the expression profile and potential biological functions of lncRNA CASC15 in non-small cell lung cancer (NSCLC) have not been fully characterized.

Methods: The expression levels of CASC15 were assessed by qRT-PCR in human NSCLC tissues and by hybridization in NSCLC tissue microarray.

MicroRNA-7 inhibits neuronal apoptosis in a cellular Parkinson's disease model by targeting Bax and Sirt2.

Parkinson's disease (PD) is the second most common age-related neurodegenerative disease. MicroRNA-7 (miR-7) displays neuroprotective properties against PD. However, the biological roles of miR-7 and its underlying molecular mechanisms in PD remain unclear.

Effect of rapamycin (RAPA) on the growth of lung cancer and its mechanism in mice with A549.

Objective: To investigate the effects of rapamycin (RAPA) on the tumor growth of lung cancer in the mice bearing A549 and the mechanisms.

Methods: 60 mice with A549 lung cancer models established were randomly divided into model group, low RAPA dose group and high RAPA dose group. The low dose group underwent intraperitoneal injection of 1.

Helicobacter pylori infection and pepsinogen levels have clinical significance in hypertension patients.

Helicobacter pylori (Hp) infection is known to alter levels of pepsinogens (PG) and is correlated with several disease states, including gastric and cardiovascular diseases. This study sought to assess whether Hp infection is associated with hypertension as well as to identify the value of assessing the PG I/PG II ratio in patients with hypertension. The study included 396 individuals with hypertension who were assessed for infection with Hp by colloidal gold assay.

Up-regulation of miR-335 predicts a favorable prognosis in esophageal squamous cell carcinoma.

Introduction: MicroRNAs (miRNAs) are noncoding RNAs that regulate multiple cellular processes during cancer progression. MiR-335 has recently been identified to be involved in tumorigenesis of several cancers such as ovarian cancer and gastric cancer. However, the regulation of miR-335 in esophageal squamous cell carcinoma (ESCC) has not been reported yet.
