Tumor necrosis factor-alpha promoter polymorphism is associated with the risk of Parkinson's disease.

Inflammatory events may contribute to the pathogenesis of Parkinson's disease (PD). We conducted a case-control study in a cohort of 369 PD cases and another cohort of 326 ethnically matched controls to investigate the association of tumor necrosis factor-alpha (TNF-alpha) promoter single nucleotide polymorphisms (SNPs) with the risk of PD. The overall genotype distribution at T-1031C and C-857T sites showed significant difference between PD cases and controls (P = 0.0062 and 0.0035, respectively). However, only the more frequent -1031 CC genotype was evidently associated with PD (P = 0.0085, odds ratio: 2.96; 95% CI: 1.38-7.09). Pairwise SNP linkage disequilibrium showed -1031 and -863 sites are in strong linkage disequilibrium (D' = 0.93, Delta(2) = 0.80). Pairwise haplotype analysis among the four sites showed that -1031C-863A may act as a risk haplotype among PD cases (P = 0.0028, odds ratio: 2.18; 95% CI: 1.33-3.69).

The efficacy and safety of Chinese massage in the treatment of acute mastitis: A protocol for systematic review and meta-analysis of randomized controlled trials

Background:The incidence of acute mastitis (AM) in lactating women has been increasing year by year. If there is no timely and appropriate treatment, AM may develop into mammary abscess and septicemia. This special situation has aroused social attention. Chinese massage has been widely used in the treatment of AM in recent years, but there is no systematic review of the effect of Chinese massage on AM. We plan to explore the efficacy and safety of Chinese massage in the treatment of AM.Methods:We will use a computer to search the following 8 electronic databases (PubMed, Web of Science, Cochrane, Embase, Sinomed, China National Knowledge Infrastructure, Chongqing VIP Information, WanFang Data) on November 30, 2021. Randomized controlled trials (RCT) of Chinese massage therapy for AM were screened. Primary outcome measure: overall clinical response rate, breast pain score. Secondary outcome measures: milk secretion, temperature, mass size and time to resolution, White blood cell count, C-reactive protein, and the incidence of adverse reactions. According to the inclusion criteria and exclusion criteria, the included literature will be independently evaluated by two researchers using the RCT bias risk assessment tool in the Cochrane evaluation manual Handbook5.4, and meta-analysis will be performed by RevMan5.4 software. Funnel plots were used to analyze whether the study had publication bias.Results:We will evaluate the clinical effect of Chinese massage therapy on AM based on RCTsConclusion:This study will provide evidence-based evidence for the effectiveness and safety of Chinese massage in the treatment of AM.Protocol registration number:INPLASY2021120019.

The co-mutation of EGFR and tumor-related genes leads to a worse prognosis and a higher level of tumor mutational burden in Chinese non-small cell lung cancer patients

BackgroundLung cancer is the leading cause of cancer mortality in China. The clinicopathologic features and genetic profile of Chinese lung cancer patients need to be investigated. This study evaluated the gene mutation profile, analyzed the frequency of concurrent genes in epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) patients, and determined its prognostic value.MethodsWe collected the clinical data from 151 initially diagnosed patients NSCLC. Tumor samples underwent targeted next-generation sequencing (NGS). Progression-free survival (PFS) and overall survival (OS) were analyzed using the Kaplan-Meier method.ResultsAmong the 151 participants, the mutational profile revealed alterations in 29 genes, where TP53 (37.09%) and EGFR (30.46%) exhibited the highest mutation rates. Mutations in the EGFR gene were most prevalent (40%) in adenocarcinoma (LUAD) and were only present in 8.8% of participants with squamous cell carcinoma (LUSC). The most frequently mutated genes in LUAD patients were TP53 (47%), followed by KRAS (11.7%). In all 39 participants with EGFR mutations, TP53, KRAS, PIK3CA, APC, and FBXW7 were also mutated. Those with only EGFR mutation appeared to have a better prognosis; however, the difference was not statistically significant. Tumor mutational burden (TMB) was roughly significantly increased in patients who harbored EGFR and other mutant driver genes, compared with only EGFR mutant patients. The TMB value was significantly higher in those with P53 mutation than in P53 wild-type patients.ConclusionsWe described the genetic profiles of NSCLC and compared the difference in genetic profiles between LUAD and LUSC. The concomitant genetic alterations might be a poor prognostic factor for patients with EGFR mutation, and TMB might be prognostically related to the co-mutations of EGFR and other genes.     

RECQL4 regulates DNA damage response and redox homeostasis in esophageal cancer

Objective:RECQL4(a member of the RECQ helicase family)upregulation has been reported to be associated with tumor progression in several malignancies.However,whether RECQL4 sustains esophageal squamous cell carcinoma(ESCC)has not been elucidated.In this study,we determined the functional role for RECQL4 in ESCC progression.Methods:RECQL4 expression in clinical samples of ESCC was examined by immunohistochemistry.Cell proliferation,cellular senescence,the epithelial-mesenchymal transition(EMT),DNA damage,and reactive oxygen species in ESCC cell lines with RECQL4 depletion or overexpression were analyzed.The levels of proteins involved in the DNA damage response(DDR),cell cycle progression,survival,and the EMT were determined by Western blot analyses.Results:RECQL4 was highly expressed in tumor tissues when compared to adjacent non-tumor tissues in ESCC(P<0.001)and positively correlated with poor differentiation(P=0.011),enhanced invasion(P=0.033),and metastasis(P=0.048).RECQL4 was positively associated with proliferation and migration in ESCC cells.Depletion of RECQL4 also inhibited growth of tumor xenografts in vivo.RECQL4 depletion induced G0/G1 phase arrest and cellular senescence.Importantly,the levels of DNA damage and reactive oxygen species were increased when RECQL4 was depleted.DDR,as measured by the activation of ATM,ATR,CHK1,and CHK2,was impaired.RECQL4 was also shown to promote the activation of AKT,ERK,and NF-k B in ESCC cells.Conclusions:The results indicated that RECQL4 was highly expressed in ESCC and played critical roles in the regulation of DDR,redox homeostasis,and cell survival.     

Euphoric effect induced by zolpidem: a case study of magnetoencephalography

Initially, zolpidem, a non-benzodiazepine hypnotic agent, was considered to have fewer adverse reactions than traditional benzodiazepines. However, after zolpidem was approved for medical use, an increasing number of case reports have described abuse or dependence complications. We were especially interested in the cases of dependence that presented a paradoxical ‘euphoric’ effect of zolpidem. This article reports the case of a female zolpidem-dependent patient who presented with 6 years of daily use of 400–1400 mg of zolpidem. She reported subjective effects of euphoria, intense craving and the inability to stop drug ingestion. Her diagnoses were zolpidem dependence and a depressive episode induced by substance abuse. To explore the neural mechanisms of the euphoric effect caused by high-dose zolpidem, we performed repeated magnetoencephalography (MEG) recordings. Before undergoing detoxification, her MEG results indicated that cerebellar electrical signal activation increased when taking high zolpidem doses. However, the prefrontal and parietal lobes’ electrical signal activity showed a tendency to recover to a normal state as the withdrawal time progressed to completion. This case suggests that the cerebellum plays a role in the euphoria induced by high zolpidem doses and provides clues for further research.
