Analysis of individualised strategy in microvascular decompression for trigeminal neuralgia / 中华显微外科杂志

Objective:To investigate the clinical efficacy of individualised microvascular decompression (MVD) for trigeminal neuralgia (TN), so as to provide individualised treatment strategies and new thoughts for treatment.Methods:Clinical data of 46 patients who had TN and treated in the Department of Neurosurgery at the First Affiliated Hospital of Anhui Medical University from January 2021 to September 2023 were retrospectively studied. The study consisted of 19 males and 27 females, with an average age of morbidity at (58.3 ± 9.0) years old. Preoperative pain ratings and surgical outcomes were evaluated using the Barrow Neurological Institute (BNI) pain rating scale, and of which 27 patients were rated at BNI grade IV and 19 at grade V before surgery. A posterior trans-sigmoid sinus approach was applied in surgery on all patients, which could be performed in various ways depending on the vascular conditions identified during surgery. Ten patients were treated with microsurgery, 12 with endoscopic surgery and 24 with combined endoscopic surgery and microsurgery. After having identified the responsible vessel(s), a vascular decompression for the affected trigeminal nerve was performed and the nerve decompression was achieved by a polyester pad. Long-term postoperative follow-ups were conducted via telephone interviews or outpatient visits.Results:A total of 46 patients received the microvascular decompression surgery. Among them, 43 cases (93.5%) achieved immediate and complete pain relief of BNI grade I after surgery, and 3 cases (6.5%) achieved partial pain relief of BNI grade Ⅱ. Four patients developed facial numbness and sensory reduction, 2 developed facial paralysis (of House-Brackmann grade Ⅱ of 1 patient and grade Ⅲ of the other), 8 developed pneumocephalus, 4 developed postoperative fever, and 2 developed subcutaneous effusion. After treatment, the pneumocephalus and fever were cured, subcutaneous effusion was disappeared in 1 patient, but remained in the other. The mean follow-up period for the 46 patients was 16.2 (1-33) months. During the follow-up, 2 of the 3 patients of BNI grade Ⅱ immediately after surgery had complete remission to BNI grade Ⅰ and the other had recurrence and aggravation at BNI grade Ⅳ.Conclusion:The complexity of the responsible vessels is one of the important factors to be considered in the microvascular decompression strategy for trigeminal neuralgia. An individualised surgical plan according to a specific vascular condition identified in the surgery, is a best possible or worthiness surgical strategy in the treatment for a TN.

Clinicopathological features of intravascular large B-cell lymphoma and collision tumors of five cases / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics, diagnosis and differential diagnosis of intravascular large B-cell lymphoma (IVLBCL) and its collision tumors. Methods: Five cases of IVLBCL were collected, including 2 cases of collision tumors, and 1 case complicated with liver cirrhosis. The morphology and immunophenotype were analyzed. The related literature was reviewed. Results: There were 2 females and 3 males, aged from 53 to 73 years, with a median age of 65 years. The tumors were located in the lower extremities, right cerebellar hemisphere, left kidney, bilateral nasal cavity, and liver, respectively. Cases 2 and 3 were incidentally found in meningioma and renal cell carcinoma tissues, respectively. Case 5 had a background of liver cirrhosis. Morphologically, atypical large lymphoid cells were located in small blood vessels and capillary lumen, with little cytoplasm, hyperchromasia, prominent nucleoli, and obvious mitotic figures. Immunohistochemically, the IVLBCL tumor cells expressed CD20 and PAX5; 2 cases were CD5 positive. One of the 5 cases was GCB phenotype, and 4 cases were non-GCB phenotype. All cases expressed C-MYC (positive rate was 10%-40%). PD-L1 was positive in 4 cases (positive rate was 60%-90%). Ki-67 proliferation index was 70%-90%. CKpan, CD3, TDT, and CD34 were negative. In case 2, meningioma cells were positive for PR, EMA, and vimentin, but negative for CKpan and PD-L1. In case 3, renal carcinoma cells were positive for CKpan, PAX8, EMA, vimentin, CAⅨ and CD10, while PD-L1 was negative. No EBER expression (by in situ hybridization) or C-MYC gene translocation (FISH, break-apart probe) was detected in any of the 5 cases. Three patients were followed up, and all died within 1-13 months. Conclusions: IVLBCL is a highly aggressive lymphoma, with occult clinical manifestations and poor prognosis. Collision tumors of IVLBCL are extremely rare. A better understanding of IVLBCL would help pathologists avoid misdiagnoses.

The Mechanism of miR-124 in Depression / 生物化学与生物物理进展

Depression is a prevalent mental illness worldwide, its multifaceted pathogenesis is still in the exploratory stage. MicroRNA (miRNA), as a crucial epigenetic regulator, plays an important role in depression. miR-124 is one of the most abundant miRNAs in the central nervous system including neurons and microglia, and involved in various biological events like neuron development and differentiation, synaptic and axonal growth, neural plasticity, inflammation and autophagy. Recent studies have reported abnormal expression of miR-124 in both depression patients and animal models. Most of the studies showed that miR-124 is upregulated in the hippocampus or prefrontal cortex in stress-induced rodent depression animal models such as CUMS, CSDS, CORT, CRS and LH but some evidence for divergence. Upregulation of miR-124 expression may be involved in depression-like behavior via CREB/BDNF/TrkB pathway, GR pathway, SIRT1 pathway, apoptosis and autophagy pathways by directly targeting these genes including Creb, Bdnf, Sirt1, Nr3c1, Ezh2 and Stat3. The downregulation of miR-124 expression in neurons is mainly involved in the neurogenesis and neuroplasticity impairments in depression by targeting the Notch signaling pathway and DDIT4/TSC1/2/mTORC1 pathway. The downregulation of miR-124 expression also was found in the activated microglia in the stress-induced models, and resulted in neuroinflammation. In summary, the abnormal expression of miR-124 in the brain of depression-related models and its related mechanisms are complex and even contradictory, and still need further research. This review provides a summary of the research progress of miR-124 in depression.

An Enhancer LncRNA Regulates NFE2 Expression and Proliferation in Human Leukemic K562 Cells / 生物化学与生物物理进展

ObjectiveTranscription factor NFE2 was observed abnormal expression in myeloproliferative neoplasm (MPN) patients. However, how NFE2 is transcriptionally regulated remains ambiguous. This study aims to explore the elements and molecular mechanisms involved in the transcriptional regulation of NFE2. MethodsActive enhancers were predicted by public NGS data and conformed experimentally via dual luciferase reporter assay. After that, PRO-seq and GRO-seq data was used to detect enhancer RNAs transcribed from these enhancers. RACE was utilized to clone the full length enhancer RNA (eRNA) transcripts, and RT-qPCR was used to measure their expression in different leukemia cell lines as well as the transcript levels during induced differentiation. Finally, to investigate the molecular function of the eRNA, overexpression and knockdown of the eRNA via lentivirus system was performed in K562 cells. ResultsWe identified three enhancers regulating NFE2 transcription, which located at -3.6k, -6.2k and +6.3k from NFE2 transcription start site (TSS) respectively. At the -3.6k enhancer, we cloned an eRNA transcript and characterized that as a lncRNA which was expressed and located in the nucleus in three types of leukemia cell lines. When this lncRNA was overexpressed, expression of NFE2 was upregulated and decreases of K562 cell proliferation and migration ability were observed. While knocking down of this lncRNA, the level of NFE2 decreases correspondingly and the proliferation ability of K562 cells increases accordingly. ConclusionWe identified an enhancer lncRNA that regulates NFE2 transcription positively and suppresses K562 cell proliferation.

Relationship Among Fungal Diversity at Different Levels of Root System of Stellaria dichotoma var. lanceolata， Soil Properties， and Main Components of Medicinal Materials in Lithosol Habitats / 中国实验方剂学杂志

ObjectiveTo explore the interaction among root fungi of Stellaria dichotoma var. lanceolata， soil factors， and main components of medicinal materials in lithosol habitats. MethodHigh-throughput sequencing technology was employed to determine the fungal community of the root system of S. dichotoma var. lanceolata at different levels （bulk soil， rhizosphere soil， rhizoplane soil， and root interior） and the soil properties of the root system （bulk and rhizosphere）， and the relationship among the fungal community， soil properties， and the main components of medicinal materials was analyzed. ResultThe total phosphorus， available phosphorus， alkaline nitrogen， dissolved organic carbon， and soil water content in the rhizosphere soil of S. dichotoma var. lanceolata were slightly higher than those in the rhizosphere， but the difference was not significant. Ascomycota is the dominant phylum of root fungi in S. dichotoma var. lanceolata. In the progressive level of bulk-rhizosphere-rhizoplane-root interior system， although the fungal diversity gradually decreased， the abundance of Hypocreales， a new phylum （unclassified_ k_ Fungi）， Helotiales， and Natipusilales gradually increased， among which Hypocreales is the most important fungal group in the root system of S. dichotoma var. lanceolata. The structural equation model （SEM） shows that the physicochemical factors of the root-soil play an important regulatory role in the fungal community and the main components of medicinal herbs， with soil total nitrogen， alkaline nitrogen， soil water content， and pH being the main regulatory factors. Soil nitrogen content is the key to promoting the main components of the medicinal herbs， and Penicillium fungi are the key fungal group to regulate the main components of the medicinal herbs. ConclusionIt highlights that the physicochemical properties of the soil of S. dichotoma var. lanceolata play a crucial role in the fungal community and the components of medicinal materials. Hypocreales fungi in the root of S. dichotoma var. lanceolata were an important group， and Penicillium fungi had a certain role in mediating the components of medicinal materials.

Advances in relapse risk factors of anti-N-methyl-D-aspartate receptor encephalitis / 中华神经科杂志

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune encephalitis mediated by anti-NMDAR antibody. Current studies have found that most patients with anti-NMDAR encephalitis have a good prognosis after immunotherapy and tumor therapy, but there are still 4.5%-36.4% patients with relapse. It is important to identify the risk factors for the prevention of relapse. This article aims to review the relapse risk factors of NMDAR encephalitis in order to provide help for the prevention of relapse.

Correlation of serum antibody titers with clinical features and prognosis of anti leucine-rich glioma inactivated 1 antibody encephalitis / 中华神经科杂志

Objective:To analyze the relationship between serum antibody titers, clinical characteristics, and prognosis in patients with encephalitis induced by anti leucine-rich glioma inactivated 1 (LGI1) antibody.Methods:Clinical data of 20 patients diagnosed with encephalitis in the Department of Neurology, First Hospital of Shanxi Medical University from February 2015 to February 2021 were collected and retrospectively analyzed. Patients were divided into 2 groups based on their serum anti LGI1 antibody titers, namely the high titer group (1∶100, 1∶320) and the low titer group (1∶10, 1∶32). The clinical characteristics, laboratory test results, and prognosis of the 2 groups of patients were compared. Relusts The age of the 20 patients with anti LGI1 antibody encephalitis ranged from 27 to 69 (53.5±11.2) years, with a male to female ratio of 1∶1. There were 9 patients in the low titer group and 11 patients in the high titer group. There was no statistically significant difference in the types and quantities of clinical symptoms between the 2 groups. Patients in the high titer group were more prone to abnormal lesions on cranial magnetic resonance imaging (10/11 vs 3/9, P=0.014). There was no statistically significant difference between the 2 groups in the presence or absence of cerebrospinal fluid anti LGI1 antibodies (9/11 vs 4/9, P=0.160). During the follow-up, it was found that 1/20 patient died of pulmonary embolism, 7/20 of patients were able to recover to their predisease state, and 9/20 of patients had residual memory impairment. In the high titer group, 3/11 of patients experienced recurrence, while there was no recurrence in the low titer group. There was no statistically significant difference in the neurological prognosis between the 2 groups at 3 months of discharge and follow-up (the number of patients whose modified Rankin Scale score≤2: 10/10 vs 8/9, P=0.474). Conclusions:Patients with high serum anti LGI1 antibody titers are more likely to develop intracerebral lesions. Higher antibody titers may be associated with a higher risk of disease recurrence. There was no significant correlation between serum antibody titers and neurological outcomes.
