RESUMO

There are insufficient studies comparing the efficacy of aminolevulinic acid hydrochloride topical powder (ALA) photodynamic therapy (PDT) against Nocardia rubra cell wall skeleton (Nr-CWS) therapy in the treatment of cervical low-grade squamous intraepithelial lesion (LSIL) with human papillomavirus (HPV), especially for long-term efficacy. Patients with cervical LSIL and HPV infection were divided into 3 treatment groups based on their own choice. All patients had a follow-up test including HPV testing, cytology and colposcopy at 4 to 6 months and 12 months after the treatment. Among142 patients, patients received 51 ALA PDT and 41 patients received Nr-CWS. Another 50 patients who refused treatment were included in the Observers group. Four to six months or 12 months after treatment, there was significant difference between 3 groups in the clearance rate of HR-HPV infection and the complete remission (CR) rates of cervical LSIL; the CR rates of cervical LSIL in the ALA PDT group was significantly higher than the Nr-CWS group; but there was no significant difference between 2 groups in the clearance rate of HPV infection. The CR rates of cervical LSIL and the clearance rate of HPV infection in the ALA PDT group was significantly higher than the Observers group; the CR rates of cervical LSIL and the clearance rate of HPV infection in the Nr-CWS group was significantly higher than the Observers group; there was no significant difference in the recurrence rates in ALA PDT and Nr-CWS group after 12 months. Both of ALA PDT and Nr-CWS group had lower recurrence rate than the Observers group. The effect of ALA PDT is similar to Nr-CWS in the clearance rate of HR-HPV infection. Compared to the Nr-CWS group, the CR rates of cervical LSIL were considerably greater in the ALA PDT group. The effect of ALA PDT in the clearance rate of HPV infection and CR rates of cervical LSIL was significantly higher than the follow-up group; Both of ALA PDT and Nr-CWS group had lower recurrence rate than the Observers group. For cervical LSIL with HPV infection, ALA PDT is a very successful therapeutic method that is noninvasive.

RESUMO

This study was to conduct a meta-analysis to explore the impact of gross total resection (GTR) and subtotal resection (STR) on survival outcomes in glioma patients. Relevant studies were searched in multiple databases from the available date of inception through 30 December 2021. The weighted mean differences (WMDs), relative risks (RRs), or hazard ratios (HRs) with 95% confidence intervals (CIs) were used to access the effect of GTR versus STR treatments on the outcomes. The histology (low-grade or high-grade) and study population (children and adults) were used for subgroup analysis. Sensitivity analysis was performed for all outcomes. Begg's test and trim-and-fill method were used for publication bias. Totally 100 studies enrolling 62,129 patients were selected in this meta-analysis. The summary results showed that GTR was superior in improving 1-, 2-, 3-, 5-, 10-, 15-year overall survival (OS), OS time, 1-, 3-, 5-year progression-free survival (PFS), recurrence, local control and seizure control among glioma patients. In addition, high-grade patients who underwent GTR had improvements in 1-, 2- and 3-year OS, OS time, and 1-year PFS, while low-grade patients receiving GTR had improvements in 2-, 5- and 15-year OS, recurrence, seizure control, and tumor progression compared with those receiving STR. GTR was likely to be more effective on survival outcomes than STR among patients with gliomas.

RESUMO

Preserving genome stability is essential to prevent aging and cancer. Dietary restriction (DR) is the most reproducible non-pharmacological way to improve health and extend lifespan in various species. Whether DR helps to preserve genome stability and whether this effect is altered by experimental variables remain unclear. Moreover, DR research relies heavily on experimental animals, making the development of reliable in vitro mimetics of great interest. Therefore, we tested the effects of sex and feeding regimen (time-restricted eating, alternate day fasting and calorie restriction) on genome stability in CF-1 mice and whether these effects can be recapitulated by cell culture paradigms. Here, we show that calorie restriction significantly decreases the spontaneous micronuclei (MN), a biomarker of genome instability, in bone marrow cells of females instead of males. Alternate day fasting significantly decreases cisplatin-induced MN in females instead of males. Unexpectedly, daily time-restricted eating significantly exacerbates cisplatin-induced MN in males but not in females. Additionally, we design several culture paradigms that are able to faithfully recapitulate the key effects of these DR regimens on genome stability. In particular, 30% reduction of serum, a mimetic of calorie restriction, exhibits a strong ability to decrease spontaneous and cisplatin-induced MN in immortalized human umbilical vein endothelial cells. We conclude that the effects of different DR regimens on genome stability are not universal and females from each diet regimen sustain a more stable genome than males. Our results provide novel insight into the understanding of how DR influences genome stability in a sex and regimen dependent way, and suggest that our in vitro DR mimetics could be adopted to study the underlying molecular mechanisms.

RESUMO

Glioma represents the most common primary cancer of the central nervous system in adults. Glycosylation is a prevalent post-translational modification that occurs in eukaryotic cells, leading to a wide array of modifications on proteins. We obtained the clinical information, bulk RNA-seq data, and single-cell RNA sequencing (scRNA-seq) from The Cancer Genome Atlas (TCGA), Chinese Glioma Genome Atlas (CGGA), Gene Expression Omnibus (GEO), and Repository of Molecular Brain Neoplasia Data (Rembrandt) databases. RNA sequencing data for normal brain tissues were accessed from the Genotype-Tissue Expression (GTEx) database. Then, the glycosylation genes that were differentially expressed were identified and further subjected to variable selection using a least absolute shrinkage and selection operator (LASSO)-regularized Cox model. We further conducted enrichment analysis, qPCR, nomogram, and single-cell transcriptome to detect the glycosylation signature. Drug sensitivity analysis was also conducted. A five-gene glycosylation signature (CHPF2, PYGL, GALNT13, EXT2, and COLGALT2) classified patients into low- or high-risk groups. Survival analysis, qPCR, ROC curves, and stratified analysis revealed worse outcomes in the high-risk group. Furthermore, GSEA and immune infiltration analysis indicated that the glycosylation signature has the potential to predict the immune response in glioma. In addition, four drugs (crizotinib, lapatinib, nilotinib, and topotecan) showed different responses between the two risk groups. Glioma cells had been classified into seven lines based on single-cell expression profiles. The five-gene glycosylation signature can accurately predict the prognosis of glioma and may offer additional guidance for immunotherapy.

RESUMO

Nonylphenol (NP) is an environmental chemical that affects apoptosis and male infertility. In our study, we found that a high concentration of NP could down-regulate the expression of microRNA-361-3p (miR-361-3p) in the murine GC-1 spermatogonia cell line and in vivo in murine spermatogonia. Additionally, one direct target of this miR, the 3' untranslated region of Killin (Klln) mRNA, was identified. Klln encodes a transcription factor that directly regulates the expression of Tp73 (transcriptionally active p73), whose encoded protein can up-regulate the expression of Puma (p53 upregulated modulator of apoptosis). Thus, our investigation revealed that the expression of Klln, Tp73, and Puma increased upon NP-dependent down-regulation of miR-361-3p, which eventually leads to apoptosis of spermatogonia.

RESUMO

The patient complained of recurrent sore throat for 2 years, who was diagnosed parapharyngeal abscess or tonsillitis for four times during June 16, 2012 to April 16, 2013. Special physical examination: left or right lateral pharyngeal wall is slightly elevated. Routine blood test showed increasing white blood cells and neutrophils. Oropharyngeal CT showed right lateral pharyngeal wall swelling and abscess formation? Repeated puncture showed no obvious purulent secretions. Symptoms were improved after anti-inflammatory treatment, but it recurrently happened later. Bilateral tonsillectomy was performed under general anesthesia on April 29, 2013. Pathological report (May 6, 2013) showed: (left) chronic tonsillitis with lymphoid hyperplasia; chronic inflammation in (right) tonsil tissue, and salivary gland tissue is also observed, considering as the hyperplasia of ectopic salivary gland tissue and interstitial lymphocytic oinfiltration.
