Objective: This study aims to investigate the anatomical relationship among the nerve roots, intervertebral space, pedicles, and intradural rootlets of the cervical spine for improving operative outcomes and exploring neuroventral decompression approach in posterior endoscopic cervical discectomy (PECD). Methods: Cervical computed tomography myelography imaging data from January 2021 to May 2023 were collected, and the RadiAnt DICOM Viewer Software was employed to conduct multiplane reconstruction. The following parameters were recorded: width of nerve root (WN), nerve root-superior pedicle distance (NSPD), nerve root-inferior pedicle distance (NIPD), and the relationship between the intervertebral space and the nerve root (shoulder, anterior, and axillary). Additionally, the descending angles between the spinal cord and the ventral (VRA) and dorsal (DRA) rootlets were measured. Results: The WN showed a gradual increase from C4 to C7, with measurements notably larger in men compared to women. The NSPD decreased gradually from the C2–3 to the C5–6 levels. However, the NIPD showed an opposite level-related change, notably larger than the NSPD at the C4–5, C5–6, and C7–T1 levels. Furthermore, significant differences in NIPD were observed between different age groups and genders. The incidence of the anterior type exhibited a gradual decrease from the C2–3 to the C5–6 levels. Conversely, the axillary type exhibited an opposite level-related change. Additionally, the VRA and DRA decreased as the level descended, with measurements significantly larger in females. Conclusion A prediction of the positional relationship between the intervertebral space and the nerve root is essential for the direct neuroventral decompression in PECD to avoid damaging the neural structures. The axillary route of the nerve root offers a safer and more effective pathway for performing direct neuroventral decompression compared to the shoulder approach.

ObjectiveTo explore the biological foundation of colorectal adenoma in damp-heat accumulation syndrome and the possible anti-tumor mechanism of Shenbai Jiedu prescription. MethodEight patients with colorectal adenoma in damp-heat accumulation syndrome， 11 patients with non-damp-heat accumulation syndrome， and 10 patients with colorectal cancer recruited by Jiangsu Provincial Hospital of Traditional Chinese Medicine from February 2019 to December 2020 meeting the inclusion criteria were clinically obtained， and the tissue of the three groups of patients was subjected to transcriptome sequencing to screen for the differentially expressed genes between the syndrome and the diseases. The intersection of the differentially expressed genes between the syndrome and the disease was taken for further screening of the differentially expressed genes sequentially increasing or sequentially decreasing in patients with non-damp-heat accumulation syndrome， damp-heat accumulation syndrome， and colorectal cancer， and functional enrichment analysis and signaling pathway enrichment analysis were carried out. Real-time polymerase chain reaction （Real-time PCR） was used to detect the effect of Shenbai Jiedu prescription on the expression of the above key differential genes. ResultBy comparing the damp-heat accumulation syndrome and non-damp-heat accumulation syndrome， a total of 384 differentially expressed genes were screened， of which 203 were up-regulated genes， and 181 were down-regulated genes. By comparing the colorectal adenoma of colorectal cancer and damp-heat accumulation syndrome， a total of 2 965 differentially expressed genes were screened， of which 2 460 were up-regulated genes， and 505 were down-regulated genes. The intersection of differentially expressed genes of the two groups was taken， and a total of 58 differentially expressed genes with the same changes were screened. The gene ontology functions were mainly enriched in UDP-galactose： β-N-acetylglucosamine beta-1，3-galactosyltransferase activity， N-acetyllactosaminide beta-1，3-N-acetylglucosaminyltransferase activity， and poly-N-acetyllactosamine biosynthetic process. Kyoto Encyclopedia of Genes and Genomes （KEGG） signaling pathways were mainly enriched in glycosphingolipid biosynthesis-globo and isoglobo series， glycosphingolipid biosynthesis-lacto and neolacto series， and IL-17 signaling pathway. Shenbai Jiedu prescription significantly inhibited the expression of key genes involved in the enrichment， such as FOSB and B3GALT5， in a dose-dependent manner （P<0.05）. ConclusionGlycolipid metabolism may be the biological foundation of colorectal adenoma in damp-heat accumulation syndrome， and Shenbai Jiedu prescription may inhibit colorectal adenoma carcinogenesis by down-regulating the expression of FOSB and B3GALT5.

ObjectiveTo observe the effects of Shenbai Jiedu prescription on fecal metabolomics and intestinal flora diversity distribution in patients with colorectal adenoma and explore its potential targets. MethodA total of 21 patients diagnosed with colorectal adenoma were enrolled in this study. Following a four-week administration of Shenbai Jiedu prescription， their clinical symptoms were observed， and fecal samples of patients before and after treatment were collected. Untargeted metabolomics and metagenomic analysis based on liquid chromatography-mass spectrometry （LC-MS） were employed to investigate the possible metabolic pathway of Shenbai Jiedu prescription and its influence on the distribution of intestinal flora in patients. ResultThe total scores of traditional Chinese medicine （TCM） syndromes of patients after drug administration decreased significantly （P<0.01）. The results of untargeted metabolomics showed that the distribution of metabolites exhibited aggregation before and after drug administration， and a total of 106 differential metabolites were screened out （P<0.05）. The Kyoto encyclopedia of genes and genomes （KEGG） enrichment analysis revealed that arginine-proline metabolism， ferroptosis， glycine， and serine and threonine metabolism were significantly enriched metabolic pathways （P<0.05）. Notably， L-4-hydroxyglutamate semialdehyde， glutathione， isopentenyl pyrophosphate， creatinine， 4-acetamido-2-aminobutanoic acid， and guanidoacetic acid were found to be involved in these aforementioned metabolic pathways. Furthermore， the association between these metabolites and different intestinal flora was analyzed， and the results showed that Shenbai Jiedu prescription could interfere with metabolic pathways such as amino acid and ferroptosis in patients with colorectal adenoma by regulating intestinal flora such as Lachnoclostridium， Eggerthella， and Dialister （P<0.05）. ConclusionShenbai Jiedu prescription may improve the clinical symptoms of patients by increasing the abundance of intestinal beneficial bacteria， reducing the abundance of harmful bacteria， and regulating metabolic pathways such as amino acid and ferroptosis in patients with colorectal adenoma. This study may provide some research ideas and directions for Shenbai Jiedu prescription to interfere with colorectal adenoma recurrence and carcinogenesis.

Colorectal adenoma is a benign tumor originating from the mucosal glandular epithelium of the colorectum and belongs to the category of intraepithelial neoplasia. Its etiology and pathogenesis are not completely clear， and some patients have genetic factors. In recent years， with the improvement in living standards， the incidence of colorectal adenoma has gradually increased due to high-fat diets， intestinal flora disorder， and emotional disturbance. As one of the precancerous lesions of colorectal cancer， colorectal adenoma is increasingly threatening human health. Surgical resection is the most direct and effective method for the treatment of colorectal adenoma， but some patients with colorectal adenoma have the possibility of recurrence after resection. At present， there is still a lack of effective prevention and treatment measures for the recurrence of colorectal adenoma. Traditional Chinese medicine （TCM） plays a unique advantage in improving the clinical symptoms of patients with colorectal adenoma and preventing postoperative recurrence and carcinogenesis. Therefore， this review summarized the clinical research and mechanism of TCM compounds in the prevention and treatment of colorectal adenoma in recent years. The clinical study on the prevention and treatment of colorectal adenoma by TCM compounds can be divided into internal treatment， external treatment， and internal and external combined treatment. The internal treatment mainly focuses on strengthening the spleen， and the external treatment includes retention enema， acupoint application， and other methods. The internal and external combined treatment is mainly based on the internal administration of TCM compounds combined with acupuncture， retention enema， and acupoint stimulation. The study on the mechanism of TCM compounds in preventing and treating colorectal adenoma was mainly explored from the aspects of regulating intestinal flora， regulating cell proliferation immune function， and achieving anti-inflammation. This review summarized the research progress of TCM compounds in the prevention and treatment of colorectal adenoma in recent years and provided a reference for future treatment with TCM.

Objective:To analyze the factors related to the occurrence of electrocoagulation syndrome after esophageal tumor endoscopic submucosal dissection (ESD), thus to construct and validate a nomogram prediction model.Methods:A total of 240 patients who underwent esophageal tumor ESD in the First Affiliated Hospital of Xi'an Medical University, Huazhou District of Weinan City People's Hospital of Shaanxi Province, and Chenggu County Hospital of Shaanxi Province from October 2018 to May 2024 were selected as the study objects. The patients were divided into a modeling group and a validation group using the "createDataPartition" of caret package in R software at a ratio of 7∶3. Univariate and multivariate logistic regression were used to analyze the factors related to the occurrence of esophageal tumor post-endoscopic submusocal dissection electrocoagulation syndrome (PEECS) in the modeling group, and the nomogram prediction model was constructed. C-index and calibration curve were used to verify the prediction model.Results:All data in the modeling group ( n=168) and the validation group ( n=72) were comparable. Univariate analysis showed that gender ( OR=2.15, 95% CI: 1.38-3.76, P=0.004), age ( OR=2.53, 95% CI: 1.39-4.61, P=0.001), surgical time ( OR=5.88, 95% CI: 2.15-8.41, P<0.001) and lesion length ( OR=5.16, 95% CI: 1.85-7.33, P<0.001) were related factors influencing the occurrence of esophageal tumor PEECS. Multivariate analysis showed that gender ( OR=2.94, 95% CI: 1.46-5.33, P=0.011), age ( OR=2.12, 95% CI: 1.20-3.88, P=0.042), surgical time ( OR=4.62, 95% CI: 2.11-7.26, P<0.001) and lesion length ( OR=3.93, 95% CI: 1.78-5.94, P=0.003) were independent factors for the occurrence of esophageal tumor PEECS. Based on the above indexes, a nomogram prediction model for the occurrence of esophageal tumor PEECS was constructed, and its C-index value was 0.787 (95% CI: 0.692-0.863). The calibration curve showed that with the modeling group as the internal verification and the validation group as the external verification, the predicted probability was in good agreement with the actual probability. Conclusion:Gender, age, surgical time and lesion length are independent factors influencing the occurrence of esophageal tumor PEECS. The nomogram prediction model based on the above indexes has high predictive efficacy.

Fibromyalgia syndrome (FMS), also known as fibromyalgia, is clinically characterized by diffuse chronic muscle and bone pain, accompanied by fatigue, sleep disturbances, depressive episodes, and cognitive and intestinal dysfunction. Due to lack of clear specific laboratory indicators and appropriate imaging examinations, FMS diagnosis is mostly based on clinical symptoms, but FMS clinical symptoms of lack specificity, and current clinical diagnostic criteria are mostly exclusive criteria, which is prone to missed diagnosis and misdiagnosis. In order to further promote the standardized diagnosis and treatment of FMS, this paper makes extensive references to laboratory-related diagnostic indexes of FMS (Tau, adiponectin, serum cathepsin S, cystatin C, serum ferritin, nitric oxide, neutrophil/lymphocyte ratio, platelet distribution width and mean platelet volume) at home and abroad, aiming to provide new ideas for early diagnosis and intervention of FMS.
