RESUMEN
Objective: To investigate a modified fusional convergence parameter-total convergence amplitude/distance angle and its relationship with exotropia control, stereoacuity, and other visual functions in intermittent exotropia. Methods: The cross-sectional study included children diagnosed with intermittent exotropia at the First Affiliated Hospital of Nanjing Medical University from August 2020 to June 2021. A modification was made by combining total convergence amplitude using synoptophore and distance angle at distance using prism bars to calculate total convergence amplitude/distance angle. Exotropia control at distance and near measured by Office-based Scale for Assessing Control was classified as good control (scale 0-1) and poor control (scale 2-5). Statistical analysis was performed using Spearman correlation analysis, Mann-Whitney U test, Fisher's exact test, χ2 test, logistic regression analysis, and mediation effect analysis. Results: The study included 212 patients, of which 105 (49.5%) were male and 107 (50.5%) were female. The median (interquartile range) age was 9.0 (8.0, 10.0) years. Of 211 cases, 201 (94.8%) had binocular fusional function, while 11 cases (5.2%) did not have binocular fusional function. Among patients with binocular fusional function, inverse correlation was observed between total convergence amplitude and exotropia control scores for both distance (r=-0.427, P<0.001) and near (r=-0.194, P=0.006). Total convergence amplitude/distance angle was an independent predictive factor for exotropia control at distance (OR=0.195; 95%CI, 0.060-0.630; P=0.006) and near (OR=0.252; 95%CI, 0.085-0.746; P=0.013). Stereoacuity at distance (OR=3.110; 95%CI, 1.311-7.379; P=0.010) and near (OR=2.780; 95%CI, 1.401-5.517; P=0.003) were also factors associated with distance exotropia control. Mediation analysis revealed that stereoacuity was not a mediating factor between the ratio and distance control (distance: P=0.066; near: P=0.181). In patients with ratio≥1.5 °/PD, all the 15 patients demonstrated good control. On the contrary, patients with ratio<1.5 °/PD showed worse exotropia control (distance: P=0.001; near: P=0.040) and larger angles of deviation (distance: P<0.001; near: P<0.001). Conclusion: The modified fusional ratio, total convergence amplitude/distance angle, combining synoptophore and prism bars, could be used to evaluate the severity of intermittent exotropia. A higher ratio may be associated with poorer exotropia control. Though it may also be associated with distance exotropia control, stereoacuity is not the mediating factor between the modified ratio and distance exotropia control.

PURPOSE: The efficacy and safety of local excision (LE) for small (< 1â2 cm) colonic neuroendocrine tumors (NETs) is controversial due to the higher metastasis risk when compared with rectal NETs. The study aimed to evaluate the metastasis risk of T1 colonic NETs and compare patients' long-term prognosis after LE or radical surgery (RS). METHODS: The Surveillance Epidemiology and End Results database was used to identify patients with T1 colonic NETs (2004â2015). Multivariable logistic regression was performed to assess factors associated with metastasis risk. Propensity score matching was used to balance the variables. Cancer-specific survival (CSS) and overall survival (OS) were calculated to estimate the prognosis of patients with T1N0M0 colonic NETs who underwent LE or RS. RESULTS: Of the 610 patients with colonic NETs, 46 (7.54%) had metastasis at diagnosis. Tumor size (11-20 mm) (OR = 9.51; 95% confidence interval (CI): 4.32â21.45; P < 0.001), right colon (OR = 15.79; 95% CI 7.20â38.56; P < 0.001), submucosal infiltration (OR = 2.08; 95% CI 0.84â5.57; P = 0.125) were independent risk factors associated with metastasis. Of the 515 patients with T1N0M0 colonic NETs, the overall long-term prognosis of LE was as good as that of RS groups (after matching, 5-year CSS: 97.9% vs. 94.6%, P = 0.450; 5-year OS: 92.7% vs. 85.6%, P = 0.009). CONCLUSION: Tumor size (11â20 mm) and site (right colon) are associated with metastasis in T1 colonic NETs. In the absence of metastasis, LE could be a viable option for 0â10 mm T1 colonic NETs with well/moderate differentiation in the left colon in terms of long-term survival.

Objective: To investigate the expression level of WT1 gene in patients with classical Philadelphia chromosome (Ph)-negative myeloproliferative neoplasms (MPN) and its correlation with clinical features. Methods: A retrospective study included 252 patients with newly diagnosed MPN in Zhongnan Hospital of Wuhan University from January 2015 to March 2023, including 128 males and 124 females, agedï¼»Mï¼Q1ï¼Q3ï¼ï¼½62 (53, 69) years. The WT1-positive group (n=93) and the WT1-negative group (n=159) were split based on the level of WT1 gene expression, and the variations in clinical indicators between the two groups were compared. Its levels of expression in each subtype and its relationships to thrombotic events and clinically significant variables were analyzed. As of March 31, 2023, the follow-up period [M (Q1, Q3)] was 12.0(6.5,21.0)months. The risk factors of thrombosis in MPN patients were analyzed by using the logistic regression analysis. Results: The WT1 gene expression level in the overall bone marrow samples of 252 patients with newly diagnosed MPN was 0.30% (0.10%, 1.10%). The expression level in primary myelofibrosis (PMF) patients was 1.45% (0.41%, 3.24%), which was higher than 0.15% (0.02%, 0.32%), 0.37% (0.16%, 1.09%) in essential thrombocythemia (ET) and polycythemia vera (PV) patients (both P<0.05). Positive correlations were found between WT1 gene expression levels and JAK2V617F gene mutation load, RDW, MPV (r=0.478, 0.346, 0.236, all P<0.01). While negative correlations between WT1 gene expression levels and PLT, LYM, PTTA, LDH were found (r=-0.339, -0.170, -0.206, -0.388, all P<0.01). Patients in the WT1-positive group exhibited a higher percentage of somatic symptoms, splenomegaly, positive JAK2V617F gene mutation, and higher levels of RDW, LDH, NEUT, and MPV compared to the WT1-negative group. In contrast, the proportion of triple-negative (negative for all three hot mutations of JAK2V617F, CALR and MPL) was lower, and the levels of PLT, LYM and PTTA were lower (all P<0.05). The thrombotic event rates of WT1-positive group and WT1-negative group were 32.3% (30/93) and 32.1% (51/159), respectively, and the difference was not statistically significant (P=0.883). Logistic regression analysis showed that male (OR=2.41,95%CI:1.02-5.71,P=0.046) and positive JAK2V617F gene mutation (OR=3.96,95%CI:1.50-10.42,P=0.005) were risk factors for thrombotic events in ET patients. Conclusions: WT1 gene expression is elevated in PMF patients and correlated with indicators of disease progression and transformation in MPN patients. It can be utilized as an auxiliary diagnostic indicator for classical MPN staging but is not correlated with the incidence of thrombotic events. Male and positive JAK2V617F gene mutation are risk factors for thrombotic events in ET patients.

OBJECTIVE: To analyze the expression of TMEM64 in hepatocellular carcinoma (HCC) and investigate the effect of TMEM64 expression level on proliferation and invasion of HCC cells in vitro. METHODS: We analyzed the expression level of TMEM64 in HCC and adjacent tissues based on data from TCGA and GTEx databases. The prognostic value of TMEM64 for HCC patients was examined using Kaplan-Meier survival analysis and a Cox regression model, and a nomogram was constructed based on TMEM64 expression and clinical characteristics of the patients. Functional enrichment analysis was performed to explore the potential signaling pathways, and immune cell infiltration was assessed using single sample gene set enrichment analysis. We also performed cell experiment to observe the changes in proliferation, migration, and invasion in HCCLM3 cells with TMEM64 knockdown and in Huh7 cells with TMEM64 overexpression using CCK-8, EdU, colony formation, Transwell, and wound healing assays. RESULTS: The expression level of TMEM64 was significantly higher in HCC than in the adjacent tissues (P < 0.05). Kaplan-Meier analysis suggested that a high expression of TMEM64 was associated with poor outcomes of the patients (P < 0.05). Multivariate Cox regression analysis indicated that a high TMEM64 expression was an independent risk factor for overall survival of HCC patients (P < 0.05). TMEM64 expression level was negatively correlated with the levels of immune cell infiltration by NK cells, CD8 + T cells, and plasma pDCs cells (P < 0.05). GO, KEGG, and GSEA enrichment analyses showed that TMEM64 was significantly enriched with tumor invasion and metastasis pathways. The nomogram and calibration curves indicated a moderate prediction reliability of the model. In the cell experiment, TMEM64 knockdown obviously suppressed and TMEM64 overexpression markedly promoted the proliferation, migration, and invasion of HCC cells (P < 0.01). CONCLUSION: A high TMEM64 expression may serve as an independent risk factor for poor prognosis of HCC and promotes proliferation, migration, and invasion of HCC cells in vitro.

OBJECTIVE: The aim of this study was to assess the clinical efficacy of oblique lateral interbody fusion (OLIF) and posterior lumbar interbody fusion (PLIF) for lumbar brucellosis spondylitis. PATIENTS AND METHODS: Between April 2018 and December 2021, 80 cases of lumbar brucellosis spondylitis admitted to our institution were evaluated for eligibility and randomly assigned to either PLIF (group A, lesion removal by posterior approach + interbody fusion + percutaneous pedicle screw internal fixation) or OLIF (group B, lesion removal by anterior approach + interbody fusion + percutaneous pedicle screw internal fixation). The outcome measures included operative time, intraoperative bleeding, hospital stay, preoperative and postoperative visual analogue scale (VAS) ratings, American Spinal Injury Association (ASIA) classification, Cobb angle, and interbody fusion time. RESULTS: PLIF resulted in shorter operative time and hospital stay and less intraoperative bleeding vs. OLIF (p<0.05). All eligible patients showed significantly lower VAS scores, and smaller ESR values and Cobb angles after treatment (p<0.05), but no significant intergroup differences were observed (p>0.05). The two groups showed similar preoperative ASIA (American Spinal Injury Association) classification and interbody fusion time (p>0.05). PLIF was associated with better ASIA classification at three months postoperatively vs. OLIF (p<0.05). CONCLUSIONS: Both surgical techniques are efficient at removing the lesion, relieving pain, maintaining spinal stability, promoting implant fusion, and facilitating prognostic inflammation control. PLIF features a shorter surgical duration and hospital stay, less intraoperative bleeding, and greater neurological improvement vs. OLIF. Nevertheless, OLIF outperforms PLIF in the excision of peri-vertebral abscesses. PLIF is indicated for posterior spinal column lesions, particularly those with spinal nerve compression in the spinal canal, whereas OLIF is indicated for structural bone deterioration in the anterior column, particularly for those with perivascular abscesses.

OBJECTIVE: This study analyzed evidence on the association between prognostic nutritional index (PNI), controlling nutritional status (CONUT), geriatric nutritional risk index (GNRI), and mini-nutritional assessment-short form (MNA-SF) and mortality after hip fracture. MATERIALS AND METHODS: The online databases of PubMed, Scopus, Web of Science, Embase, and Google Scholar were accessed for literature reporting the association between PNI/CONUT/GNRI/MNA-SF and mortality after hip fracture. Data were pooled in a random-effects model. RESULTS: 13 studies were eligible. Meta-analysis of six studies showed that individuals with low GNRI had a significantly higher risk of mortality as compared to those with high GNRI (OR: 3.12 95% CI: 1.47, 6.61 I2=87% p=0.003). Meta-analysis of three studies found that low PNI was not a significant predictor of mortality amongst hip fracture patients (OR: 1.42 95% CI: 0.86, 2.32 I2=71% p=0.17). On pooling data from five studies, it was noted that patients with low MNA-SF scores had a significantly higher risk of mortality in comparison to those with higher scores (OR: 3.61 95% CI: 1.70, 7.70 I2=85% p=0.0009). Only one study was available on CONUT. Heterogeneity of cut-offs and variable follow-up were important limitations. CONCLUSIONS: Our results indicate that MNA-SF and GNRI can predict mortality in elderly patients undergoing surgery for hip fractures. Data is scarce on PNI and CONUT to draw strong conclusions. Variation in cut-offs and follow-up period are important limitations which need to be addressed by future studies.

Objective: To evaluate the screening performance of hypersensitive quantitative fecal immunochemical test (hs-qFIT) and qualitative fecal occult blood test (FOBT) for colorectal cancer and advanced adenoma. Methods: Consecutive participants scheduled to undergo colonoscopy from April 2020 to April 2021 in Qilu Hospital of Shandong University were included in the study. All the participants were 50-75 years old and at moderate to high risk for colorectal cancer. Participants completed hs-qFIT and two kinds of qualitative FOBTs (colloidal gold method and chemical-immunization method) before colonoscopy. The sensitivities and specificities of hs-qFIT and two qualitative FOBTs for colorectal cancer and advanced adenoma were compared. Results: A total of 910 participants were enrolled in the study, including 451 males and 459 females, aged (59.6±6.4) years. There were 22 cases (2.4%) of colorectal cancer, 61 cases (6.7%) of advanced adenoma, 276 cases (30.3%) of non-advanced adenoma, 194 cases (21.3%) of non-adenomatous polyp, 85 cases (9.3%) of other colorectal lesion and 272 cases (29.9%) of non-colorectal lesion. The sensitivities of hs-qFIT for detecting colorectal cancer increased from 72.7% (95%CI: 49.6%-88.4%) to 100% (95%CI: 81.5%-100%) with cut-off value decreasing from 200 ng/ml to 10 ng/ml, and the sensitivities of both colloidal gold method and chemical-immunization method were 63.6% (95%CI: 40.8%-82.0%) (P=0.008). The detection stability of hs-qFIT for colorectal cancer was higher than colloidal gold method (P=0.016) and chemical-immunization method (P=0.031). The sensitivity for detecting advanced adenoma of hs-qFIT at 10 ng/ml was 52.5% (95%CI: 39.4%-65.2%), which was significantly higher than that of colloidal gold method (13.1%, 95%CI: 6.2%-24.8%, P<0.001) and chemical-immunization method (6.6%, 95%CI: 2.1%-16.7%, P<0.001). Conclusions: The sensitivity and detection stability of hs-qFIT for detecting colorectal cancer was higher than qualitative FOBT. Moreover, the sensitivity for detecting advanced adenoma can be further improved using a lower cut-off value.

OBJECTIVE: To investigate the expression of circPCSK5 in gastric cancer (GC) and its role in regulation of the proliferation, invasion and epithelial-mesenchymal transition (EMT) of GC cells. METHODS: High-throughput sequencing was performed in 3 pairs of GC and adjacent gastric mucosa tissues to obtain the differential expression profile of circRNA. The expression of circPCSK5 was detected in 62 patients undergoing radical surgery for GC using RT-qPCR, and the correlation between circPCSK5 expression level and clinicopathological data of the patients was analyzed. The overall survival and disease-free survival of the patients were assessed with Kaplan-Meier survival analysis, and the independent risk factors affecting the patients' prognosis were analyzed using Cox proportional hazards regression model. The stability and subcellular localization of circPCSK5 were assessed using RNase R and actinomycin D assays, fluorescence in situ hybridization and nucleocytoplasmic separation assay. CCK-8 assay, EdU assay and Transwell assay were employed to examine the changes in proliferation, migration and invasion of GC cells with circPCSK5 knockdown or overexpression; Western blotting and RT-qPCR assays were used to detect the expression levels of EMT markers in the transfected cells. RESULTS: The expression of circPCSK5 was significantly upregulated in GC tissues and cells (P < 0.001, P < 0.01). The expression level of circPCSK5 was positively correlated with tumor size, vascular invasion, lymph node metastasis and AJCC stage of GC (P < 0.05). The overall survival and disease-free survival were significantly lower in GC patients with high circPCSK5 expression than in those with low circPCSK5 expression (P < 0.001). High circPCSK5 expression was an independent risk factor for a poor prognosis of GC patients (P < 0.05). Knockdown of circPCSK5 significantly inhibited the proliferation, migration and invasion of HGC27 cells (P < 0.01), increased the expressions of E-cadherin, and decreased the expression of N-cadherin and vimentin (P < 0.01). CircPCSK5 overexpression promoted the proliferation, migration and invasion of MKN45 cells (P < 0.01), reduced E-cadherin expression and increased N-cadherin and vimentin expressions (P < 0.01). CONCLUSION: CircPCSK5 is highly expressed in GC and promotes the proliferation, invasion and EMT of GC cells, suggesting its potential as a prognostic biomarker and therapeutic target for GC.

OBJECTIVE: Chronic cerebral hypoperfusion (CCH) can cause ischemic cerebral white matter lesions (IWML). The aim of this study was to explore the roles of A2A receptors (A2AR) in IWML and the effect of methylation in A2AR gene. MATERIALS AND METHODS: SD rat model of CCH was constructed by bilateral common carotid artery occlusion (BCCAO) method. The rats were then treated with DNA methyltransferase (DNMT) inhibitor (decitabine), agonist (CGS21680) and A2AR inhibitor (SCH58261). Morris water maze and Kluver-Barrera staining were used to assess spatial learning and reference memory after IWML, respectively. Gene transcription and protein expression were measured by qRT-PCR, Enzyme-linked immunosorbent assay (ELISA) and Western blotting, respectively. The concentration of malondialdehyde (MDA), activity of superoxide dismutase (SOD) and DNMT were detected by assay kit. Methylation of A2AR gene promoter region was detected by bisulfite sequencing PCR (BSP). RESULTS: We found that the down-regulated expression of A2AR in corpus callosum under CCH was associated with IWML and cognitive impairment. We further showed that A2AR agonist can reduce the IWML under CCH, and A2AR inhibitor can aggravate the IWML under CCH. We also found that the expression level of DNMTs in corpus callosum and the methylation level in the promoter region of A2AR gene were increased under CCH. DNMT inhibitors could protect white matter by inhibiting the methylation of A2AR promoter and rescue the downregulation of A2AR under CCH. CONCLUSIONS: Our results demonstrate that the downregulation of A2AR mediates IWML in CCH, and A2AR downregulation is related to the increased methylation of A2AR gene promoter. DNMT inhibitors play a protective role in IWML.

The aim of this study is to explore the pathogenesis of granulomatous lobular mastitis (GLM) via pathology and molecular biology. This single-center study included 28 female patients who received a diagnosis of pathologically confirmed GLM from January 2020 to September 2020 at Dongzhimen Hospital of Beijing University of Chinese Medicine. Tissue samples and serum were collected during radical surgery. Western blot and immunohistochemistry were employed to determine caspase-1 and gasdermin D (GSDMD). Transmission electron microscopy (TEM) was used to observe the ultrastructure of cells. Finally, the results were analyzed. The expression of activated GSDMD and caspase-1 were all increased in the lesion group (P < 0.05). The TEM results showed clear features of pyroptosis. We concluded that pyroptosis was important in the development of GLM and inhibitad apoptosis to some degree. The inhibition of pyroptosis response may help to discover new drugs for GLM.

The recurrence of osteosarcoma (OS) after reconstruction using Ti6Al4V prostheses remains a major problem in the surgical treatment of OS. Modification of the surfaces of Ti6Al4V prostheses with antitumor functions is an important strategy for improving therapeutic outcomes. Magnesium (Mg) coating has been shown to be multifunctional: it exhibits osteogenic and angiogenic properties and the potential to inhibit OS. In this study, we determined the proper concentration of released Mg2+ with respect to OS inhibition and biosafety and evaluated the anti-OS effects of Mg-coated Ti6Al4V scaffolds. We found that the release of Mg2+ during short-term and long-term degradation could significantly inhibit the proliferation and migration of HOS and 143B cells. Increased cell apoptosis and excessive autophagy were also observed, and further evidence of AMPK/mTOR/ULK1 signaling pathway activation was obtained both in vitro and in vivo, which suggested that the biofunctional scaffolds induce OS inhibition. Our study demonstrates the ability of an Mg coating to inhibit OS and may contribute to the further application of Mg-coated Ti6Al4V prostheses.

RESUMEN
AIM: To accelerate the acquisition of high-resolution magnetic resonance imaging (MRI) by using the three-dimensional (3D) matrix sequence with compressed sensing and to compare it with conventional two-dimensional (2D) proton-density (PD) and fast spin-echo (FSE) sequences. MATERIALS AND METHODS: 3D matrix, 2D FSE, and PD sequences were acquired from 68 participants using 3 T magnetic resonance imaging (MRI). Two radiologists scored image quality independently on a four-point scale. The structural similarity index (SSIM), and signal- (SNRs) and contrast-to-noise ratios (CNRs) of different anatomical structures of the knee were assessed and compared between sequences using Wilcoxon signed-rank tests and Cohen's kappa. RESULTS: The median acquisition time reduction was 44.5%. There was a substantial to perfect agreement for the rating between the 3D matrix FSE and 2D FSE or PD sequences when evaluating cartilage, subchondral bone, and ligaments (κ=0.783-872, p>0.05). The mean SSIM values between the 3D matrix FSE and 2D FSE, and between the 3D matrix PD and 2D PD sequences was 0.994 and 0.971, respectively, which are acceptable. No significant differences were found in SNR between the 3D matrix FSE and 2D FSE, and between the 3D matrix PD and 2D PD sequences, even though the SNR appeared to be higher on routine 2D sequences. The CNR of subchondral bone-meniscus, subchondral bone-joint fluid, and meniscus-joint fluid did not differentiate significantly between the 3D matrix sequence and routine 2D sequences. CONCLUSIONS: 3D matrix reduced the acquisition time in routine clinical knee MRI without the loss in image quality, SNR, and CNR.
