Objective:To study the comprehensive surgical treatment of brucellosis with chest wall cysts as the main manifestation.Methods:Retrospective analysis was made on the general information epidemiological characteristics, clinical manifestations, laboratory examinations, imaging examinations, treatment and outcomes of five patients with brucellosis mainly manifested by chest wall cysts admitted to the 948 Hospital of the People's Liberation Army from July 2019 to June 2022.Results:Among the 5 patients, there were 4 males and 1 female, aged between 23 and 64 years old, with a clear history of contact with cattle and sheep. The main clinical manifestation was painless cystic masses on the chest wall. Both the serum tiger red plate agglutination test (RBPT) and the test tube agglutination test (SAT) were positive. Four cases were infected with Brucella and one case was infected with Actinobacillus pleuropneumoniae (considered as Brucella infection based on the overall condition). All patients exhibited abnormal chest wall signals (manifesting as hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging) on magnetic resonance imaging(MRI), and were ultimately diagnosed with brucellosis presenting predominantly as chest wall cysts. After complete removal of the chest wall cyst through surgery, a combination treatment of rifampicin capsules and doxycycline hyclate tablets was given for 6 weeks. There were no significant adverse reactions and the wound healed in one stage. During the postoperative follow-up period of 11 - 40 months, MRI reexamination demonstrated no evidence of chest wall cyst recurrence, and all SAT results were negative. Conclusions:Patients with brucellosis presenting as chest wall cysts are clinically rare and lack specific symptoms. Surgical resection of the affected lesion combined with early, standardized, combined, and full course antimicrobial therapy results in a good prognosis for the patient.

Objective To investigate the efficacy of transcranial direct current stimulation(tDCS)on sleep disorder in patients with Parkinson's disease(PD).Methods From July 2021 to July 2023,patients with PD and sleep disorders in the Department of Neurosurgery of the Second People's Hospital of Guangdong Province were selected.The enrolled patients were divided into sham stimulation group(n=28)and true stimulation group(tDCS)(n=29)according to the inclusion and exclusion criteria.MDS-UPDRS,PDSS and other rating scales were used to evaluate the patients.Before and after tDCS treatment,MS-11 was used for intelligent sleep monitor-ing.The baseline and improvement of sleep disorders in the two groups before and after treatment were analyzed.Results Before tDCS treatment,there was no significant difference in general conditions and scale scores between the two groups(P＞0.05).There was no significant difference in polysomnographic monitoring results between the two groups before treatment(P＞0.05).Compared with pre-treatment,there was no significant difference in sleep monitoring results in the sham stimulation group(P＞0.05),while the sleep duration and sleep efficiency signifi-cantly increased,the nighttime awakening duration,nighttime awakening frequency,MDS-UPDRS-Ⅲ score,and LEDD dose significantly decreased in the true stimulation group,with statistical significance(P＜0.05).Conclusion Pharmacological treatment combined with tDCS treatment is effective for sleep disorders and motor function in patients with PD,which could increase the sleep duration and sleep efficiency of PD patients with sleep disorders to a certain extent,reduce the nighttime awakening duration and frequency,thereby improving the fatigue symp-toms during the daytime,and improving the efficacy of conventional pharmacological treatment for PD.

Objective:To screen the differentially expressed genes(DEGs)under high phosphate-induced calcification in the vascular smooth muscle cells(VSMCs)by mRNA high-throughput sequencing technology,and to analyze the key genes and signaling pathways involved in the VSMCs calcification.Methods:The human VSMCs were divided into control group and model group.The cells in model group was exposed to the high-phosphate medium,while the cells in control group were cultured in DMEM supplemented with 10%fetal bovine serum under the same conditions.The VSMCs in two groups,stably transfected,were cultured for 12 d.The morphology of the cells in two groups were observed and photographed under inverted microscope.The DEGs were selected by Hisat2 software,and Gene Ontology(GO)functional and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis were performed by Stringtie software from three aspects,such as biological processes(BP),molecular functions(MF),and cellular components(CC).The calcification of the cells in two groups was observed by Von Kossa staining method.Real-time fluorescence quantitative PCR(RT-qPCR)method was used to analyze the expression levels of alkaline phosphatase(ALP),bone morphogenetic protein 2(BMP2),alpha-smooth muscle actin(α-SMA),tumor protein 53(Tp53),glutathione peroxidase 4(GPX4),ferritin light chain 1(Ftl1),and glycosylphosphatidylinositol-specific phospholipase D1(GPLD1)mRNA in the cells in two groups.Results:Compared with control group,there were 2 524 DEGs in the cells in model group,and there were 1 368 upregulated DEGs and 1 156 downregulated DEGs.Clustering of DEGs between the cells in two groups was distinct.The GO functional and KEGG pathway enrichment analysis results showed that the upregulated DEGs were primarily involved in regulating the microtubule cytoskeleton,cell polarity,protein localization,and cell cycle regulation among BPs;in constructing cell membrane,microtubule organization,chromosomes,and kinetochore among CCs;and functioning in phosphatidylinositol phosphate,Rho GTPase protein binding,transmembrane transport,and protein kinase regulatory activity among MFs.Downregulated DEGs were mainly involved in cytoplasmic translation,protein membrane localization,mRNA metabolism,and protein endoplasmic reticulum localization among BPs;in forming ribosome subunits,cell membrane,and autophagy among CCs;and functioning in single-stranded DNA,ribonucleoprotein complex,growth factor binding,regulating protein kinase activity,and catalytic activity among MFs.Seven signaling pathways were significantly enriched in upregulated genes,most notably in the biosynthesis of glycosylphosphatidylinositol(GPI)anchors;whereas 18 signaling pathways were significantly enriched in the downregulated genes,most notably in ferroptosis.The RT-qPCR results showed that compared with control group,the expression levels of GPX4,Ftl1,and Tp53 mRNA in the cells in model group were significantly decreased(P<0.01),while the expression level of GPLD1 mRNA was significantly increased(P<0.01);compared with control group,the expression level of α-SMA mRNA in the cells in model group was significantly decreased(P<0.01),and the expression levels of ALP and BMP2 mRNA were significantly increased(P<0.01).Conclusion:The VSMCs underwent calcification and normal cells exhibit the DEGs.The key signaling pathways in the calcification induced by high phosphate in the VSMCs include ferroptosis and GPI anchor biosynthesis,mediated primarily through GPX4,Ftl1,Tp53,and GPLD1.

Objective:To explore the intervention effect of sensorimotor training on cognitive function, balance and fall risk of elderly patients with schizophrenia.Methods:The 60 hospitalized elderly schizophrenic patients in Wuxi Mental Health Center were randomly divided into experimental group and control group from June to September 2021, with 30 cases in each group. The control group implemented traditional exercise on the basis of routine nursing. The experimental group received 8-week and 24 times sensorimotor training on the basis of the routine nursing. The Chinese version of the Mini Mental State Examination (MMSE) was used to assess the cognitive level of patients, the Modified Morse Fall Scale (MMFS) was used to assess the risk of falls, and the Berg Balance Scale (BBS) was used to assess the balance function.Results:After 8 weeks of intervention, the total score of MMSE was (26.72 ± 1.71), higher than the total score of the control group (22.36 ± 1.93), the factor scores of temporal orientation, spatial orientation, recollection, attention and calculation, memory and language ability in the experimental group were (4.90 ± 0.31), (4.72 ± 0.53), (2.86 ± 0.35), (4.66 ± 0.61), (2.83 ± 0.47), (6.76 ± 1.09), higher than scores of the control group (4.36 ± 0.56), (3.93 ± 0.66), (2.57 ± 0.50), (3.64 ± 1.03), (2.18 ± 0.67), (5.68 ± 1.02), and the difference was statistically significant( t values were 2.53-9.06, all P< 0.05). The total score of MMFS in the experimental group was (5.93 ± 1.49), which was lower than that in the control group (8.75 ± 2.30). The difference was statistically significant ( t=-5.51, P<0.01). The total score of BBS in the experimental group was (38.83 ± 1.71), which was higher than that in the control group (30.89 ± 1.93). The difference was statistically significant ( t=16.43, P<0.01). Conclusions:Sensorimotor training can improve the level of balance, cognitive function and reduce the risk of falls in elderly patients with schizophrenia.

The biodiversity of the mycobiome, an important component of the oral microbial community, and the roles of fungal-bacterial and fungal-immune system interactions in the pathogenesis of oral lichen planus (OLP) remain largely uncharacterized. In this study, we sequenced the salivary mycobiome and bacteriome associated with OLP. First, we described the dysbiosis of the microbiome in OLP patients, which exhibits lower levels of fungi and higher levels of bacteria. Significantly higher abundances of the fungi Candida and Aspergillus in patients with reticular OLP and of Alternaria and Sclerotiniaceae_unidentified in patients with erosive OLP were observed compared to the healthy controls. Aspergillus was identified as an "OLP-associated" fungus because of its detection at a higher frequency than in the healthy controls. Second, the co-occurrence patterns of the salivary mycobiome-bacteriome demonstrated negative associations between specific fungal and bacterial taxa identified in the healthy controls, which diminished in the reticular OLP group and even became positive in the erosive OLP group. Moreover, the oral cavities of OLP patients were colonized by dysbiotic oral flora with lower ecological network complexity and decreased fungal-Firmicutes and increased fungal-Bacteroidetes sub-networks. Third, several keystone fungal genera (Bovista, Erysiphe, Psathyrella, etc.) demonstrated significant correlations with clinical scores and IL-17 levels. Thus, we established that fungal dysbiosis is associated with the aggravation of OLP. Fungal dysbiosis could alter the salivary bacteriome or may reflect a direct effect of host immunity, which participates in OLP pathogenesis.

BACKGROUND/AIMS: The integration of multiple profiling data and the construction of a transcriptional regulatory network may provide additional insights into the molecular mechanisms of hepatocellular carcinoma (HCC). The present study was conducted to investigate the deregulation of genes and the transcriptional regulatory network in HCC. METHODS: An integrated analysis of HCC gene expression datasets was performed in Gene Expression Omnibus. Functional annotation of the differentially expression genes (DEGs) was conducted. Furthermore, transcription factors (TFs) were identified, and a global transcriptional regulatory network was constructed. RESULTS: An integrated analysis of eight eligible gene expression profiles of HCC led to 1,835 DEGs. Consistent with the fact that the cell cycle is closely related to various tumors, the functional annotation revealed that genes involved in the cell cycle were significantly enriched. A transcriptional regulatory network was constructed using the 62 TFs, which consisted of 872 TF-target interactions between 56 TFs and 672 DEGs in the context of HCC. The top 10 TFs covering the most downstream DEGs were ZNF354C, NFATC2, ARID3A, BRCA1, ZNF263, FOXD1, GATA3, FOXO3, FOXL1, and NR4A2. This network will appeal to future investigators focusing on the development of HCC. CONCLUSIONS: The transcriptional regulatory network can provide additional information that is valuable in understanding the underlying molecular mechanism in hepatic tumorigenesis.
