on. MDRO infections in malignant tumors mainly include carbapenem-resistant Acinetobacter baumannii and carbapenem-resistant Escherichia coli. There are differences in terms of MDRO strains in different years and different infection sites, and there are many risk factors regarding MDRO infection in patients with malignant tumors. Intervention should be taken in order to reduce the rate of MDRO infection.Breast cancer (BC) in adolescents and young adults (AYAs) accounts for 5.6% of BC in all women. BC in this population is often characterized as aggressive. Two-thirds of BC in AYAs belong to the hormone-receptor positive (HR(+))/human epidermal growth factor receptor 2 negative (HER2(-)) subtype. However, the underlying pathogenesis of this subtype has not been fully elucidated. To study HR(+)/HER2(-) BC in AYAs, we downloaded the available RNA-seq data from The Cancer Genome Atlas (TCGA) database and then performed differential expression gene screening and constructed a protein-protein interaction (PPI) network, identified the key genes, and did gene set enrichment analysis (GSEA). Based on the analyses, 32.26% of patients were in stage III. Additionally, we identified 1671 differentially expressed genes (DEGs) and 35 key genes. In addition, GSEA showed that ether lipid metabolism and complement and coagulation cascades were significantly enriched in the GNAI1 high expression phenotype. The key genes CXCL2, CXCL5, CXCL3, GPR37L1, NPY2R, OXGR1, NPW, CCL21, GNAI1, SAA1, GRM4, HCAR2, CX3CL1, GRM8, CCL28, SSTR1, PENK, P2RY12, NMUR1, NMU, ADCY5, TAS1R1, OXER1, GNG13, CCL16, CCR8, NPY5R, CXCL11, CXCL10, CXCL9, CXCL1, CXCL6, CCR4, and ANXA1 may be molecular markers of tumorigenesis of HR(+)/HER2(-) BC in AYAs. In addition, ether lipid metabolism and complement and coagulation cascades may be key pathways for GNAI1 regulation in HR(+)/HER2(-) BC in AYAs.SIRT3 is a mitochondrial deacetylation protein that can promote the invasion and migration of cancer cells. We explored the effects of SIRT3 regulation of the AMPK/PPAR signaling pathway on triglycerides and the invasion and metastasis of cervical cancer cells. Immunohistochemical methods were used to detect SIRT3. The expression of AMPK and PPAR proteins in different cervical lesions was analyzed in combination with clinicopathological parameters. qRT-PCR and western blotting were used to determine the expression levels of SIRT3 in the C33a and SiHa cervical cancer cell lines. AF-353 manufacturer To observe the effects of altering SIRT3 levels by lentivirus transfection and the consequent changes in AMPK and PPAR protein expression, oil red O staining was used to determine intracellular triglycerides, and scratch assays and Transwell chamber experiments were performed to evaluate cervical cancer cell migration and invasion. Our data indicate that SIRT3, AMPK, and PPAR protein expression levels show an increasing trend with cervical lesion severity and are related to the degree of lymph node metastasis and differentiation; moreover, increased expression of SIRT3 can promote the expression of AMPK and PPAR proteins, is beneficial to the formation of intracellular neutral fat, and enhances the ability of cells to metastasize and invade. Our results suggest that SIRT3 activates AMPK/PPAR signaling pathways involved in cancer lipid metabolism and promotes metastasis and cell invasion.Primary large B-cell lymphomas involving the cerebellopontine angle (CPA) are uncommon. Fewer than 20 cases of large B-cell lymphoma at the CPA have been reported worldwide. Herein, we report a rare case of B-cell lymphoma in a 67-year-old woman who presented with dysphagia and dizziness and showed a lesion involving the right CPA on magnetic resonance imaging (MRI). The primary diagnosis was metastatic tumor; however, postoperative pathology confirmed a diffuse large B-cell lymphoma. The initial symptoms were resolved completely at the 2-month postoperative follow-up, and the postoperative course was uneventful. Large B-cell lymphoma should be included in the differential diagnosis of CPA lesions.Intramedullary cysticercosis of the cervical spine is extraordinarily rare; prior reports are limited to single cases. We review cases of intramedullary cysticercosis, and summarize the features and outcome. Herein, we report a 38 year old woman with progressive quadriplegia, paresthesia in bilateral upper limbs, neck pain and headache for 1 month. She had dyspnea for 1 week. A gross total resection was performed, and after the surgery, the patient was given prednisolone per day orally, for 2 weeks. Oral albendazole 400 mg/day was started 2 days after the start of prednisolone. Ag-ELISA was performed 2 months after the completion of treatment and no residual lesion was seen. At the 6-month postsurgical follow-up, no recurrence of the cysticercosis was noted. Cysticercosis of the cervical spine is extraordinarily rare. Preoperative identification of intramedullary cysticercosis is challenging, and the exact diagnosis depends on histopathological evidence and Ag-ELISA. With symptoms of the nervous system, surgical resection should be performed in time.

Breast cancer is still a leading threat to women's lives. Long non-coding RNAs (lncRNA) associated with cancer progression are getting attention. The objective of this study was to investigate the role of lncRNA MAFG-antisense 1 (MAFG-AS1) and mechanisms of action in breast cancer.

The expression of MAFG-AS1, microRNA-3196 (miR-3196) and transcription factor AP-2 alpha (TFAP2A) was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The cell proliferation was assessed by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay. The number of colonies was observed through colony formation assay. The protein levels of Cyclin D1, Ki67, Bcl-2 associated X protein (Bax), B-cell lymphoma2 (Bcl-2), Hexokinase II (HK2), lactate dehydrogenase A (LDHA), TFAP2A, Janus kinase 2 (JAK2), phosphorylated-JAK2 (p-JAK2), signal transducer and activator of transcription 3 (STAT3), and phosphorylated-STAT3 were quantified by western blot. The cell apoptosis was monitored using flow cytometry.
