Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

Background and Aims:Gastric cancer remains a common malignancy worldwide with a poor prognosis and limited response to current therapies.Ferroptosis,a novel form of regulated cell death,has emerged as a promising therapeutic target in cancer.Terminal nucleotidyltransferase 5B(TENT5B)is downregulated in various tumors,but its role in gastric cancer and ferroptosis remains unclear.This study aimed to investigate the expression pattern and biological function of TENT5B in gastric cancer and to elucidate its underlying mechanisms in regulating ferroptosis.Methods:The expression of TENT5B in gastric cancer was analyzed using TCGA and GEO datasets,and further validated in gastric cancer tissues and cell lines by qRT-PCR and Western blotting.CCK-8,colony formation,wound healing,and Transwell assays were performed to evaluate the effects of TENT5B overexpression on cell proliferation and migration.Ferroptosis was assessed by measuring cell viability,lipid ROS,and MDA levels.Bioinformatics analysis,mRNA stability assays,and rescue experiments were conducted to explore the molecular mechanisms.A subcutaneous xenograft mouse model was used to validate the in vivo effects.Results:TENT5B was significantly downregulated in gastric cancer tissues and cells.Overexpression of TENT5B inhibited cell proliferation and migration while promoting ferroptosis.Mechanistically,TENT5B enhanced PRKAA2 mRNA stability and upregulated its expression,thereby exerting tumor-suppressive effects.In vivo,TENT5B overexpression suppressed tumor growth and elevated PRKAA2 expression.Conclusion:TENT5B functions as a tumor suppressor in gastric cancer by stabilizing PRKAA2 mRNA,promoting ferroptosis,and inhibiting cancer progression.These findings suggest that TENT5B may serve as a promising molecular target for ferroptosis-based therapeutic strategies in gastric cancer.

Objective This study aimed to explore the expression trends of innate immune cells and immune-checkpoint molecules validated by data calculation in the process of oral mucosal carcinogenesis,as well as to explore methods of suppressing oral mucosal carcinogenesis based on immunotherapy by predicting their interactions.Me-thods 1)The cancer genome atlas(TCGA)database comprehensively scores immune cells and immune-checkpoint molecules in the process of oral mucosal carcinogenesis and screens out intrinsic immune cells and immune-check-point molecules that interfere with tumor immune escape.2)Clinical patient blood routine data were collected for the statistical analysis of peripheral blood immune cells during the progression of oral mucosal carcinogenesis.Immune cells in peripheral blood that may affect the progression of oral mucosal carcinogenesis were screened.3)Immunohis-tochemical staining was performed on intrinsic immune cells and immune-checkpoint molecules validated based on da-ta calculation in various stages of oral mucosal carcinogenesis.4)Special staining was used to identify innate immune cells in various stages of oral mucosal carcinogenesis based on data-calculation verification.5)Survival analysis was conducted on intrinsic immune cells and immune-checkpoint molecules validated based on data calculation during the process of oral mucosal carcinogenesis.The association of intrinsic immune cells and immune-checkpoint molecules with the prognosis of oral squamous cell carcinoma was verified.Results The expression of monocytes and neutro-phils increased during the process of oral mucosal carcinogenesis.The expression of eosinophils showed a single peak trend of up and down.The expression of mast cells decreased.In the process of oral mucosal carcinogenesis,the ex-pression of the immune-checkpoint molecules cytotoxic T-lymphocyte-associated protein 4(CTLA4)and programmed cell death-ligand(PD-L1)increased.The expression trends of monocytes,neutrophils,and eosinophils were positively correlated with those of CTLA4 and PD-L1 immune-checkpoint molecules.The expression trend of mast cells was negatively correlated with the expression of CTLA4 and PD-L1.Monocytes,neutrophils,and eosinophils may pro-mote tumor immune escape mediated by CTLA4 and/or PD-L1,thereby accelerating the progression of oral mucosal carcinogenesis.Mast cells may inhibit tumor immune escape mediated by CTLA4 and/or PD-L1,delaying the progres-sion of oral mucosal carcinogenesis.Conclusion Therefore,interference with specific immune cells in innate immu-nity can regulate the expression of CTLA4 and/or PD-L1 to a certain extent,inhibit tumor immune escape,and delay the progression of oral mucosal carcinogenesis.

Objective To investigate the expression levels and clinical significance of differentially expressed microRNAs(miRNAs)based on high-throughput sequencing in patients with left ventricular hypertrophy(LVH)and their possible regulatory mechanisms.Methods The miRNA sequencing was performed on plasma samples from 4 LVH patients and 4 healthy volunteers,and qRT-PCR validation was performed on plasma samples from 25 healthy volunteers and 35 LVH patients.The target genes of the obtained differentially expressed miRNA were predicted.The molecular function(MF),biological process(BP)and cellular components(CC)of these miRNAs were predicted by the Gene Ontology(GO)enrichment analysis,and their signal pathways were predicted by the Kyoto Encyclopedia of Genes and Genomes analysis.Meanwhile,the protein-protein interaction network was constructed.The diagnostic values of 2 differentially expressed miRNAs(hsa-miR-942-5p and hsa-miR-184)in LVH were analyzed by the area under the receiver operating characteristic(ROC)curve(AUCROC).Results A total of 945 differentially expressed miRNAs were identified,of which 1 and 9 were observed to be significantly upregulated and downregulated,respectively.The expression levels of hsa-miR-942-5p and hsa-miR-184 were verified by qRT-PCR to be significantly downregulated.The AUCROC of hsa-miR-942-5p and hsa-miR-184 were 0.694 6 and 0.880 4,respectively.Bioinformatics analysis revealed that the target genes were mainly enriched in the cell senescence,sphingolipid metabolism,and TGF-β,p53,and diabetic metabolism related signaling pathways.Conclusion The expression levels of hsa-miR-942-5p and hsa-miR-184 in plasma of LVH patients are significantly decreased,suggesting that they have good diagnostic potential.

Objective:To analyze the efficacy of vertebroplasty combined with posterior decompression and internal fixation in the treatment of spinal metastases with neurological symptoms.Methods:This study was a retrospective analysis of 32 cases with neurological symptoms caused by spinal metastatic tumor in the Department of Orthopedics, Beijing Friendship Hospital, Capital Medical University from June 2016 to January 2022. All 32 patients (20 males, 12 females) aged between 39 to 85 years were enrolled in this study, with a mean age of (64.8±11.9) years. Surgery time, bleeding volume, modified Tokuhashi score, spinal instability neoplastic score (SINS) were collected. The visual analogue score (VAS), Oswestry disability index (ODI), Karnofsky performance scale (KPS) and American spinal cord injury association (ASIA) score before surgery, 1 month after surgery, 3 months after surgery and 6 months after surgery were collected and analyzed. Measurement data with normal distribution were represented as mean±standard deviation( ± s), and the comparison before and after surgery was conducted using repeated-measures analysis of variance test. Measurement data with skewed distribution were represented as M( Q1, Q3). Results:All 32 patients were followed up for 6 months. The operation time was (209.6±49.0) min, and the blood loss was (462.9±298.3) mL. 14 patients(43.8%) were treated with blood transfusion. The modified Tokuhashi score was 8.09±2.89, and the SINS was 8.81±1.97. The VAS score before surgery, postoperative 1, 3, 6 months were 7.47±0.98, 3.87±0.87, 2.91±0.73 and 2.34±0.60, respectively. ODI score before surgery, postoperative 1, 3, 6 months were 79.13±9.50, 39.14±6.31, 34.43±6.42 and 31.08±4.80, respectively. KPS score before surgery, postoperative 1, 3, 6 months were 49.69±14.70, 64.68±15.02, 71.88±12.81 and 75.63±10.76, respectively. The ASIA grading at 6 months follow-up was improved compared to preoperative baseline. Postoperative complications occurred in 4 cases, including nerve root injury (1 case), bone cement leakage in paravertebral soft tissue (1cases), bone cement leakage in paravertebral vein(1case) and acute thoracic epidural hematoma (1case).Conclusion:Vertebroplasty combined with posterior decompression and internal fixation can effectively relieve pain, relieve the compression of spinal cord and nerve, recover nerve functions, and improve the quality of life of patients with spinal metastatic tumor.
