ABSTRACT

Intramesorectal lymph node metastasis after radical surgery of prostate cancer is rare in clinical practice. This paper reported 2 cases of intramesorectal lymph node metastasis and resection after operation for prostate cancer. Patient 1 underwent laparoscopic radical prostatectomy 5 years ago, who was followed up closely after surgery, and was diagnosed with mesorectal lymph node metastasis by MRI examination. Patient 2 underwent robot-assisted laparoscopic radical prostatectomy 2 months ago, who was followed up by pelvic MRI and mesorectal lymph node metastasis was revealed. Both patients underwent fluorescence laparoscopic mesenteric lymphadenectomy in our department. With 4 to 6 month of follow-up after surgery, MRI examination showed no recurrence of tumor.

ABSTRACT

Based on transcriptome sequencing technology, the mouse model of prediabetes treated with Huangjing Qianshi Decoction was sequenced to explore the possible mechanism of treating prediabetes. First of all, transcriptome sequencing was performed on the normal BKS-DB mouse group, the prediabetic model group, and the Huangjing Qianshi Decoction treatment group(treatment group) to obtain differentially expressed genes in the skeletal muscle samples of mice. The serum biochemical indexes were detected in each group to screen out the core genes of Huangjing Qianshi Decoction in prediabetes. Gene Ontology(GO) database and Kyoto Encyclopedia of Genes and Genomes(KEGG) database were used to conduct signaling pathway enrichment analysis of differentially expressed genes, and real-time quantitative polymerase chain reaction(RT-qPCR) was used to verify them. The results showed that the levels of fasting blood glucose(FBG), fasting insulin(FINS), insulin resistance index(HOMA-IR), total cholesterol(TC), triglycerides(TG), and low-density lipoprotein cholesterol(LDL-C) in the mouse model were significantly decreased after treatment with Huangjing Qianshi Decoction. In the results of differential gene screening, there were 1 666 differentially expressed genes in the model group as compared with the normal group, and there were 971 differentially expressed genes in the treatment group as compared with the model group. Among them, interleukin-6(IL-6) and NR3C2 genes, which were closely related to the regulation of insulin resis-tance function, were significantly up-regulated between the model group and the normal group, and vascular endothelial growth factor A(VEGFA) genes were significantly down-regulated between the model group and the normal group. However, the expression results of IL-6, NR3C2, and VEGFA genes were adverse between the treatment group and the model group. GO functional enrichment analysis found that the biological process annotation mainly focused on cell synthesis, cycle, and metabolism; cell component annotation mainly focused on organelles and internal components; and molecular function annotation mainly focused on binding molecular functions. KEGG pathway enrichment analysis found that it involved the protein tyrosine kinase 6(PTK6) pathway, CD28-dependent phosphoinositide 3-kinase/protein kinase B(PI3K/AKT) pathway, p53 pathway, etc. Therefore, Huangjing Qianshi Decoction can improve the state of prediabetes, and the mechanism may be related to cell cycle and apoptosis, PI3K/AKT pathway, p53 pathway, and other biological pathways regulated by IL-6, NR3C2, and VEGFA.

ABSTRACT

This study aims to investigate the mechanism of Linderae Radix water extract(LRWE) in the prevention and treatment of diarrhea-predominant irritable bowel syndrome(IBS-D) based on serum metabolomics. Eighteen 2-week-old male SD rats were randomized into control, IBS-D model, and LRWE groups. The rats in other groups except the control group received gavage of senna concentrate combined with restraint stress for the modeling of IBS-D. The rats in the LRWE group were administrated with LRWE(5.4 g·kg~(-1)) by gavage, and those in the control and IBS-D model groups with an equal volume of distilled water for a total of 14 days. The visceral sensitivity was evaluated by the abdominal withdrawal reflex(AWR) score, and the degree of diarrhea was assessed by the fecal water content(FWC). The morphological changes of the colon and the morphology and number of goblet cells were observed by hematoxylin-eosin(HE) and periodic acid-schiff(PAS) staining, respectively. Ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) was used for the screening of the potential biomarkers in the rat serum and their related metabolic pathways. The results showed that LRWE reduced the AWR score, decreased FWC, and alleviated visceral sensitivity and diarrhea symptoms in IBS-D rats. HE and PAS staining showed that LRWE mitigated low-grade intestinal inflammation and increased the number of mature secretory goblet cells in the colonic epithelium of IBS-D rats. A total of 25 potential biomarkers of LRWE in treating IBS-D were screened out in this study, which were mainly involved in riboflavin, tryptophan, glycine, serine and threonine metabolism, glyoxylate and dicarboxylate metabolism, and cysteine and methionine metabolism. The regulatory effects were the most significant on the riboflavin and tryptophan metabolism pathways. LRWE may alleviate the visceral hypersensitivity by promoting energy metabolism and amino acid metabolism, enhancing intestinal barrier function, and improving intestinal immune function in IBS-D rats.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of sagittal top compression reduction technique in the treatment of thoracolumbar vertebral fractures.@*METHODS@#A retrospective analysis was conducted on the clinical data of 59 patients with thoracolumbar vertebral fractures who met the selection criteria and were admitted between November 2018 and January 2022. Among them, 34 patients were treated with sagittal top compression reduction technique (top pressure group), and 25 patients were treated with traditional reduction technique (traditional group). There was no significant difference in baseline data between the two groups ( P>0.05), including gender, age, fracture segment, cause of injury, AO classification of thoracolumbar vertebral fractures, thoracolumbar injury classification and severity (TLICS) score, American Spinal Injury Association (ASIA) grading, surgical approach, preoperative vertebral body index, height ratio of the anterior margin of injured vertebra, injured vertebra angle, segmental kyphosis angle, visual analogue scale (VAS) score, and Oswestry disability index (ODI). The operation time, intraoperative blood loss, and incidence of complications between the two groups were recorded and compared. After operation, VAS score and ODI were used to evaluate effectiveness, and X-ray and CT examinations were performed to measure imaging indicators such as vertebral body index, height ratio of the anterior margin of injured vertebra, injured vertebra angle, and segmental kyphosis angle.@*RESULTS@#There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05). No complication such as dural sac, nerve root, or vascular injury was found during operation, and all incisions healed by first intention. Patients in both groups were followed up 6-48 months, with an average of 20.6 months. No loosening, breakage, or failure of internal fixation occurred during follow-up. The imaging indicators, VAS score, and ODI of the two groups significantly improved at 1 week and last follow-up when compared to preoperative ones ( P<0.05). At last follow-up, the VAS score and ODI further significantly improved when compared to 1 week after operation ( P<0.05). At 1 week after operation and last follow-up, the vertebral body index, segmental kyphosis angle, injured vertebra angle, and ODI in the top pressure group were significantly better than those in the traditional group ( P<0.05). There was no significant difference in VAS score and height ratio of the anterior margin of injured vertebra between the two groups at 1 week after operation ( P>0.05), but the two indicators in the top pressure group were significantly better than those in the traditional group at last follow-up ( P<0.05).@*CONCLUSION@#The treatment of thoracolumbar vertebral fractures with sagittal top compression reduction technique can significantly improve the quality of vertebral reduction, and is superior to traditional reduction techniques in relieving pain and improving spinal function.

ABSTRACT

This study analyzed the molecular mechanism of Huangjing Qianshi Decoction(HQD) in the treatment of prediabetes based on network pharmacology and molecular docking. The active components of HQD were identified and screened based on Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP, http://Lsp.nwu.edu.cn/tcmsp.php) and then the targets of the components and the genes related to prediabetes were retrieved, followed by identifying the common targets of the decoction and the disease. The medicinal component-target network was constructed by Cytoscape to screen key components. The protein-protein interaction(PPI) network was established by STRING and hub genes were identified by Cytoscape-CytoNCA, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) of the hub genes with R-clusterProfi-ler. Thereby, the possible signaling pathways were predicted and the molecular mechanism was deduced. A total of 79 active components of HQD and 785 diabetes-related targets of the components were screened out. The hub genes mainly involved the GO terms of tricarboxylic acid cycle, peptide binding, amide binding, hydrolase activity, and kinase activity regulation, and the KEGG pathways of AGE-RAGE signaling pathway, TNF signaling pathway, AMPK signaling pathway, IL-17 signaling pathway, and insulin signaling pathway. Western blot result showed that HQD-containing serum significantly reduced the expression of AKT1, AGE, and RAGE proteins in insulin resistance model cells. HQD's treatment of prediabetes is characterized by multiple pathways, multiple targets, and multiple levels. The main mechanism is that the components zhonghualiaoine, baicalein, kaempferol, and luteolin act on AKT1 and inhibit the AGE-RAGE axis.

ABSTRACT

Ependymal stem cells (EpSCs) are dormant stem cells in the adult spinal cord that proliferate rapidly and migrate to the site of injury after spinal cord injury (SCI). Although they can differentiate into neurons under appropriate conditions in vitro, EpSCs mainly differentiate into astrocytes in vivo. Our previous study confirmed that alternatively polarized macrophages (M2) facilitate the differentiation of EpSCs towards neurons, but the detailed mechanism remains elusive. In the present study, we found that M2 conditioned medium could upregulate the expression of Sirtuin 2 (SIRT2) in EpSCs in vitro through the BDNF/TrkB-MEK/ERK signaling pathway. As an important deacetylase, SIRT2 deacetylated stable Ac-α- tubulin (Acetyl alpha Tubulin) in microtubules and thus promoted EpSC differentiation into neurons. The present study provides a theoretical basis and a new way to improve neural recovery, such as regulating the growth and differentiation of EpSCs by increasing the proportion of M2 cells in the local microenvironment or upregulating the expression of SIRT2 in EpSCs.

ABSTRACT

BACKGROUND: Human urine-derived stem cells are newly discovered adult stem cells, characterized by rich sources, simple extraction, good proliferative ability and multi-directional differentiation potential. In recent years, human urine-derived stem cells have been used for the repair of neurological functions in urinary diseases, such as stress urinary incontinence and vesicoureteral reflux. OBJECTIVE: To explore the biological characteristics of human urine-derived stem cells and to study their repairing effect in a rat model of spinal cord injury. METHODS: Cell phenotypes of human urine-derived stem cells were detected using flow cytometry, and the immunohistochemical staining was used to identify neuron-like cells differentiated from human urine-derived mesenchymal stem cells. Then, an animal model of spinal cord injury at T9 segment was made by Allen method, and after modeling 24 Sprague-Dawley rats were assigned into spinal cord injury group or cell treatment group (n=12/group). In the cell treatment group, the model rats were injected 2 μL of 1.0×1011/L human urine-derived stem cells, while in the spinal cord injury group, the rats were administered the same volume of L-DMEM containing 10% fetal bovine serum. Basso, Beattie and Bresnahan scores were valued at 1, 10, 20, and 30 days after modeling. Spinal cord samples from all the rats were taken out at 30 days after modeling, and Luxol Fast Blue staining, microglia/macrophages staining and glial fibrillary acidic protein staining were used to value the injured area of the spinal cord and the fluorescence intensity of glial fibrillary acidic protein. RESULTS AND CONCLUSION: (1) Flow cytometry showed high expression on CD29 and CD90, and low expression on CD45 in human urine-derived mesenchymal stem cells. Moreover, human urine-derived mesenchymal stem cells could be induced to differentiating into neuron-like cells in vitro. (2) Basso, Beattie and Bresnahan scores showed no significant difference between the two groups at 1 and 10 days after modeling (P > 0.05), while, at 20 and 30 days after modeling, the scores in the cell treatment group were significantly higher than those in the spinal cord injury group (P < 0.05). (3) Luxol Fast Blue staining showed that the injured area of the spinal cord in the cell treatment group was markedly less than that in the spinal cord injury group (P < 0.05), and the glial fibrillary acidic protein showed lower fluorescence intensity in the cell treatment group than the spinal cord injury group (P < 0.05). To conclude, human urine-derived stem cells can differentiate into neuron-like cells and have therapeutic effects in the rat model of spinal cord injury.

ABSTRACT

BACKGROUND: The immediate implantation in the anterior maxillary region is in a high risk of aesthetic complications. OBJECTIVE: To assess the prognosis of the labial bone plate after anterior maxillary repair with immediate implant combined with immediate restoration. METHODS: Thirty-two patients with single failed tooth in the anterior maxillary region were subjected to implantation of ZIMMER implants immediately after minimally invasive extraction. Good primary stability was achieved and immediate restoration was carried out. Final restoration was finished after 6-12 months of osteosynthesis and gingival shaping. The loading situation of the labial bone plate was recorded at 6 months post operation. RESULTS AND CONCLUSION: Final restoration was finished with normal loading in all the patients. No bleeding and swelling of the gingiva was recorded. The horizontal absorption of the labial bone plate at the upper margin, 5 mm and 10 mm below the upper margin was (-2.12±0.05), (-1.54±0.04), and (-1.01±0.06) mm, respectively. Therefore, absorption of the labial bone plate with varying degrees exists after anterior maxillary repair with immediate implant combined with immediate restoration.

ABSTRACT

SPECT-CT integrates CT with SPECT, and can use 18F-fluorodeoxyglucose(FDG) for coincidence imaging. Its imaging can simultaneously indicate the function metabolism information from SPECT and the diagnostic information about anatomy from CT. And the target to no-target(T/NT) ratio can be calculated by using relative semi-quantitative analysis after once imaging. So SPECT-CT is one of the important imaging methods of tumor diagnosis and treatment. However, there is no accepted standard about cut-off level of T/NT ratio in the diagnosis for tumor, also about the selection location of region of interest (ROI) when you calculated the T/NT ratio. If T/NT ratio≥ 2.5 was referred as threshold in the diagnose of malignant tumor, there may be some false positive and false negative. This paper reviews the methods of the selection location of ROI for T/NT ratio in coincidence-CT imaging, and its influence factors, and its value of the diagnosis for benign malignancy, as well as its application progress in tumor diagnosis and treatment. It proves that the increased value by CT to the pure SPECT imaging is that it can more accurately detect lesions anatomically. By the way, it provide more accurate positioning information for the rang of ROI. Thereby, it provide more useful imaging information for clinical biopsy, surgery or the rang of radiotherapy target area.
