Neuroinflammatory responses play an important role in the pathogenesis of various diseases, particularly those affecting the central nervous system. Inhibition of neuroinflammation is a crucial therapeutic strategy for the management of central nervous system disorders. The intestinal microbial-gut-brain axis serves as a key regulatory pathway that modulates neuroinflammatory processes. Intestinal flora metabolites such as short-chain fatty acids, indoles and their derivatives, lipopolysaccharides, trimethylamine oxide, and secondary bile acids exert direct or indirect effects on neuroinflammation. Studies have shown that electroacupuncture (EA) modulates the composition of the intestinal microbiota and its metabolites, while also suppressing neuroinflammation by targeting the TLR4/NF- κ B, NLRP3/caspase-1, and microglial cell M2-type transformation pathways. This review discusses the mechanisms by which EA regulates neuroinflammation via intestinal microbiota and its metabolites, providing information and a foundation for further investigation of the precise therapeutic mechanisms of EA in neurological disorders.

Objective: To observe the characteristics of the evolution of liver indexes in patients with relapsed/refractory multiple myeloma (RRMM) treated with CAR-T-cells based on BCMA. Methods: Retrospective analysis was performed of patients with RRMM who received an infusion of anti-BCMA CAR-T-cells and anti-BCMA combined with anti-CD19 CAR-T-cells at our center between June 1, 2019, and February 28, 2023. Clinical data were collected to observe the characteristics of changes in liver indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), and direct bilirubin (DBIL) in patients, and its relationship with cytokine-release syndrome (CRS) . Results: Ninety-two patients were included in the analysis, including 41 patients (44.6%) in the group receiving a single infusion of anti-BCMA CAR-T-cells, and 51 patients (55.4%) in the group receiving an infusion of anti-BCMA combined with anti-CD19 CAR-T-cells. After infusing CAR-T-cells, 31 patients (33.7%) experienced changes in liver indexes at or above grade 2, which included 20 patients (21.7%) with changes in one index, five patients (5.4%) with changes in two indexes, and six patients (6.5%) with changes in three or more indexes. The median time of peak values of ALT and AST were d17 and d14, respectively, and the median duration of exceeding grade 2 was 5.0 and 3.5 days, respectively. The median time of peak values of TBIL and DBIL was on d19 and d21, respectively, and the median duration of exceeding grade 2 was 4.0 days, respectively. The median time of onset of CRS was d8, and the peak time of fever was d9. The ALT, AST, and TBIL of patients with CRS were higher than those of patients without CRS (P=0.011, 0.002, and 0.015, respectively). CRS is an independent factor that affects ALT and TBIL levels (OR=19.668, 95% CI 18.959-20.173, P=0.001). The evolution of liver indexes can be reversed through anti-CRS and liver-protection treatments, and no patient died of liver injury. Conclusions: In BCMA-based CAR-T-cell therapy for RRMM, CRS is an important factor causing the evolution of liver indexes. The evolution of liver indexes after CAR-T-cell infusion is transient and reversible after treatment.

Objective: To explore the changes in bacterial community structure, antibiotic resistance genome, and pathogen virulence genome in river water before and after the river flowing through Haikou City and their transmission and dispersal patterns and to reveal anthropogenic disturbance's effects on microorganisms and resistance genes in the aquatic environment. Methods: The Nandu River was divided into three study areas: the front, middle and rear sections from the upstream before it flowed through Haikou City to the estuary. Three sampling sites were selected in each area, and six copies of the sample were collected in parallel at each site and mixed for 3 L per sample. Microbial community structure, antibiotic resistance, virulence factors, and mobile genetic elements were analyzed through bioinformatic data obtained by metagenomic sequencing and full-length sequencing of 16S rRNA genes. Variations in the distribution of bacterial communities between samples and correlation of transmission patterns were analyzed by principal co-ordinates analysis, procrustes analysis, and Mantel test. Results: As the river flowed through Haikou City, microbes' alpha diversity gradually decreased. Among them, Proteobacteria dominates in the bacterial community in the front, middle, and rear sections, and the relative abundance of Proteobacteria in the middle and rear sections was higher than that in the front segment. The diversity and abundance of antibiotic resistance genes, virulence factors, and mobile genetic elements were all at low levels in the front section and all increased significantly after flow through Haikou City. At the same time, horizontal transmission mediated by mobile genetic elements played a more significant role in the spread of antibiotic-resistance genes and virulence factors. Conclusions: Urbanization significantly impacts river bacteria and the resistance genes, virulence factors, and mobile genetic elements they carry. The Nandu River in Haikou flows through the city, receiving antibiotic-resistant and pathogen-associated bacteria excreted by the population. In contrast, antibiotic-resistant genes and virulence factors are enriched in bacteria, which indicates a threat to environmental health and public health. Comparison of river microbiomes and antibiotic resistance genomes before and after flow through cities is a valuable early warning indicator for monitoring the spread of antibiotic resistance.

OBJECTIVE:
To investigate the expression of fibroblast growth factor receptor 2 (FGFR2) in clear cell renal cell carcinoma (ccRCC; or kidney renal clear cell carcinoma, KIRC), to analyze the relationship between the expression of FGFR2 and the clinical pathological features and prognosis of ccRCC, to study the relationship between the expression of FGFR2 and other molecules, and to explore its role in the development of ccRCC.
METHODS:
Gene expressional and clinical information of ccRCC patients were downloaded from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus(GEO) database. Next, the data were transformed and collated. In the study, 104 clinical ccRCC samples and corresponding paracancerous normal tissue samples were collected from Department of Urology, Peking University First Hospital. Immunohistochemistry (IHC) was performed and the staining results were scored, so as to compare the expression of FGFR2 in ccRCC and paracancerous normal tissues. Besides, quantify real-time polymerase chain reaction (qRT-PCR) was used to detect the mRNA expression level of FGFR2 in normal renal epithelial cell lines (293) and ccRCC cell lines (786-O, 769-P, OSRC-2, Caki-1, ACHN, and A498). In addition, the relationship between FGFR2 expression and clinical pathological characteristics (including TNM staging and pathological grading) and survival prognosis in ccRCC patients was further analyzed. Furthermore, the relationship between FGFR2 expression and B cells, T cells, natural killer (NK) cells and neutrophil infiltration in the ccRCC patients was analyzed, and the Biological General Repository for Interactionh Datasets (BioGRID) was used to builds protein-protein interaction (PPI) networks to study molecules that interacted with the FGFR2 protein.
RESULTS:
In the TCGA database, the expression of FGFR2 was down-regulated in ccRCC tissue samples compared with normal tissue samples, and the expression in the GEO database also showed this differences. Furthermore, FGFR2 expression was downregulated in ccRCC clinical samples and ccRCC cell lines, compared with corresponding paracancerous normal tissue or normal renal epithelial cell lines. In addition, FGFR2 high expression was associated with earlier, lower-level ccRCC and was associated with a better prognosis in the patients with ccRCC. Moreover, FGFR2 expression was not significantly related to B cells, T cells, NK cells and neutrophil infiltration, and the PPI network showed that FGFR2 protein interacted with certain molecules.
CONCLUSION
Our work sheds light on the potential role of FGFR2 in the development of ccRCC, suggesting that FGFR2 may serve as a prognostic marker and potential therapeutic target for patients with ccRCC.

ObjectiveLymphomatosis cerebri (LC) is a very rare variant of central nervous system lymphoma (PCNSL). However, there are few reports at present and LC has worse prognosis than other types of PCNSL. Hence, this study reports 3 cases of LC whose pathologic features had been clarified through stereotactic brain biopsy, to better characterize LC in order to improve early diagnosis and treatment. MethodsFrom January 2017 to July 2020, the clinical manifestations, imaging and neuropathology of 3 patients diagnosed with LC in Lingnan Hospital of the Third Affiliated Hospital of Sun Yat-sen University were retrospectively analyzed. ResultsThe 3 patients were 44-year-old, 61-year-old, and 64-year-old males with neurological dysfunction such as progressive cognitive decline, blurred vision, and lower limb weakness. Magnetic resonance imaging (MRI) revealed diffuse white matter lesions in the bilateral brain, which were manifested as long T1 and long T2 signal and demonstrated increased signal intensity on T2-fluid attenuated inversion recovery (T2-FLAIR) sequences and slightly higher in diffusion weighted imaging (DWI). Stereotactic brain biopsy specimen showed diffuse B cells infiltration, CD20 (+), consistent with LC. ConclusionsLC is a rare variant of central nervous system lymphoma that usually has no specific clinical performance, so the doctor can easily succumb to misdiagnosis and missed diagnosis. MRI evidence of bilateral hemispheric involvement should be alerts for this diagnosis. Brain biopsy should be early performed to clarify the pathology, which is of great significance for early diagnosis and prognosis.

OBJECTIVE:
To investigate the expression and clinical significant of VCAN and its related molecules in patients with MM.
METHODS:
Ficoll density gradient centrifugation method was used to speared the bone marrow mononuclear cell in 25 cases of MM before and after treatment, the relative mRNA expression of VCAN and their related molecules (FAK, FN, MK, and HAS) in bone marrow was detected by real-time quantitative PCR, and their protein expression was determined by Western bolt.
RESULTS:
The expression of VCAN, FK and FN in the effective group after treatment was significantly lower than that before treatment (P<0.05), however, the expression of MK and HAS showed no statistically significantly different before and after treatment (P<0.05). The expression of VCAN of patients in non remission group was significantly higher than that in control group (P<0.05). The expression of FAK and FN of patients in no remission group was significant increased as compared with the patients in newly diagnosed group (P<0.05). The relative expression of VCAN mRNA in the patients at 3rd stage was significantly higher than those at the 1st stage (P<0.05) and control group but showed no significant difference to the patients at 2nd stage (P<0.05). The expression of VCAN and its related proteins (FAK, MK, FN) showed positively correlation in bone marrow mononuclear cells of MM patients (P<0.05). The correlation between VCAN and HAS was not statistically significant (r=0.259,P>0.05). Survival analysis showed that the relative expression of VCAN mRNA was associated with OS (P=0.049) and PFS (P=0.041) in MM patients.
CONCLUSION
VCAN and its related molecules are highly expressed in MM patients; VCAN may act as potential biomarker in the development of multiple myeloma.

OBJECTIVE:
To explore the expression and clinical significance of EZH2 in DLBCL patients accompanied by HBV infection.
METHODS:
The clinicopathological data of 59 patients with DLBCL accompanied by HBV infection in our hospital from February 2015 to October 2017 were analyzed retrospectively. The patients were divided into HBV negative and HBV positive groups by serological testing before surgery. The expression of EZH2 was detected by immumohistochemical staining, and the clinicopathological characteristics and survival were analyzed and compared between these two groups.
RESULTS:
There were 30 patients (50.8%) in the HBV negative group and 29 patients (49.2%)in the HBV positive group. The differences of age, LDH level and IPI score between two groups were statistically significant (P<0.05). The expression of EZH2 in HBV- positive group was significantly higher than that in the HBV- negative group (P<0.05), where the expression of EZH2 correlated with the expression of the BCL-6 (r=0.282, P<0.05), especially in the GCB-DLBCL (r=0.549, P<0.05). PFS was not significantly different between two groups of HBV (P>0.05), while the PFS in the R-CHOP regimen group was higher than that in the CHOP regimen group (P<0.05). COX multivariate analysis showed that both the chemotherapy regimen without R and the increased level of LDH were the risk factors affecting the prognosis of DLBCL patients (P<0.05).
CONCLUSION
EZH2 highly expresses in HBV positive group, suggesting that the significance of EZH2 in DLBCL with HBV infection is worth further explore.
