ABSTRACT
Inflammation is the key driver of liver fibrosis progression in non-alcoholic fatty liver disease (NAFLD). Unfortunately, it is often challenging to assess inflammation in NAFLD due to its dynamic nature and poor correlation with liver biochemical markers. Liver histology keeps its role as the standard tool, yet it is well-known for substantial sampling, intraobserver, and interobserver variability. Serum proinflammatory cytokines and apoptotic markers, namely cytokeratin-18, are well-studied with reasonable accuracy, whereas serum metabolomics and lipidomics have been adopted in some commercially available diagnostic models. Ultrasound and computed tomography imaging techniques are attractive due to their wide availability; yet their accuracies may not be comparable with magnetic resonance imaging-based tools. Machine learning and deep learning models, be they supervised or unsupervised learning, are promising tools to identify various subtypes of NAFLD, including those with dominating liver inflammation, contributing to sustainable care pathways for NAFLD.
ABSTRACT
Objective To explore the expression of fibrinogen-like protein 1 (FGL1), the distribution of tumor-infiltrating lymphocytes (TILs), and their relationship with the prognosis of esophageal squamous-cell carcinoma (ESCC) patients. Methods We analyzed retrospectively the clinical data of 120 ESCC patients. The expression of FGL1 was detected through immunohistochemistry. The distributions of intratumoral TILs (iTILs) and stromal TILs (sTILs) were evaluated under a microscope. Survival analysis was used to evaluate the patient outcomes. Results The positive rate of FGL1 in ESCC was 18.3% (22/120), and it was connected to the TNM stage, lymph node status, and TILs. A total of 73 cases (60.8%) showed low levels of iTILs (iTILs≤10%), and 47 cases (39.2%) exhibited high iTIL levels (iTILs > 10%). Similarly, 82 cases (68.3%) presented low levels of sTILs (sTILs≤10%), and 38 cases (31.7%) manifested high sTIL levels (sTILs > 10%). The distribution of iTILs was associated with FGL1, tumor differentiation, and TNM stage, whereas the distribution of sTILs was associated with FGL1, tumor location, and TNM stage. The Kaplan–Meier survival analysis showed that tumor diameter, TNM stage, lymph node status, FGL1, and TILs were associated with the prognosis of patients with ESCC (P < 0.05). Multivariate Cox regression revealed that FGL1, TILs and TNM stage were the influencing factors of prognosis. Conclusion FGL1 expression is associated with the poor prognosis and may be a prognostic biomarker of ESCC. FGL1 combined with TILs can be used as a biomarker to predict ESCC.
ABSTRACT
Objective:To understand the present situation of self-acceptance of elderly in nursing home and explore its influencing factors, so as to provide basis for improving self-acceptance level of elderly in nursing home.Methods:Totally 415 elderly people in 3 Medical and nursing homes in Fuyang city of Anhui province were selected by Self-Acceptance Scale, and influencing factors were analyzed.Results:The total score of Self-Acceptance Scale of the elderly in nursing home was (44.11±7.25) points, the score rate was 67.86% (44.11/65), in the middle level; the results of multiple linear stepwise regression showed that the relationship with children, hobbies, number of children, length of stay in nursing home, frequency of visits and age were the main influencing factors ( F value was 48.228, P<0.001). Conclusion:The self-acceptance of the elderly in nursing home is in the middle level. The nursing home or social should pay attention to the higher age group and the newly admitted elderly in nursing home, give such people timely psychological guidance, help them to plan their later life, cultivate their interests and hobbies through recreational activities, and take corresponding measures to harmonize their relationship with their children in order to improve their self-acceptance level and promote mental health.
ABSTRACT
Objective:To investigate the effect of oblique lateral lumbar intervertebral fusion (OLIF) on inflammatory factors in patients with degenerative spinal canal stenosis (DLSS).Methods:Retrospective analysis of clinical data of 64 DLSS patients in the department of orthopedics, Jizhong Energy Fengfeng Group Hospital from June 2016 to June 2018 was performed. There were 35 males and 34 females, aged (60.70±6.27) years, and the age range was 20 to 80 years. According to the different surgical methods, they were divided into posterior decompression and internal fixation fusion (PLIF) group ( n=32) and OLIF group ( n=32). The coperation time, intraoperative bleeding volume, postoperative bed rest time, hospitalization time , the back and leg pain visual analogue score (VAS) , Japanese Orthopaedic Association(JOA) score of lumbar vertebrae and serum inflammatory factors [tumor necrosis factor-alpha(TNF-α), interleukin-1alpha(IL-1α), C-reactive protein(CRP)] were observed at preoperative, 3 months and last follow-up. Follow-up using outpatient examination and telephone interview was performed and survial up to March 2019. Measurement data were expressed as mean±standard deviation ( Mean± SD), comparison between groups was performed using independent sample t test or analysis of variance of repeated measurement data. Internal comparisons were performed using paired t tests. Count data were expressed as percentage (%), and χ2 test was used. Results:There was no significant difference in operation time between OLIF group and PLIF group ( P>0.05). In OLIF group, the amount of blood loss (119.72±30.41) mL, bedridden time (2.16±0.35) d and postoperative hospital stay (5.18±2.06) d were significantly lower than that of PLIF group[(318.26±94.62) mL, (3.17±0.54) d, (7.35±1.24) d], the differences between the two groups were statistically significant( P<0.05). All patients were followed for 8 months. The 3 months after operation and last follow-up, the VAS scores of back pain in OLIF group [(1.93±0.54) scores, (1.74±0.63) scores]were significantly lower than that in PLIF group [(4.05±0.62) scores, (3.87±0.74) scores]. The VAS scores of leg pain in OLIF group [(1.56±0.71) scores, (1.37±0.52) scores] were significantly lower than that of PLIF group [(3.74±0.79) scores, (2.53±0.59) scores]. The JOA scores of lumbar vertebrae in PLIF group [(22.57 ±1.83) scores, (24.38±1.65) scores] were significantly higher than that of PLIF group [(20.35±1.78) scores, (22.14±1.35) scores], the differences between the two groups were statistically significant( P<0.05). At 3 months after operation, the levels of serum TNF-α(16.95±3.92) ng/L, IL-1α(9.17±3.78) ng/L and CRP (1.97±0.24) mg/L in OLIF group were significantly lower than those in PLIF group [(20.46 ±4.27) ng/L, (11.51±4.25) ng/L, (2.36±0.32) mg/L]. Last follow-up, the level of serum TNF-α(13.47±3.54) ng/L, IL-1α(6.52±2.09) ng/L and CRP (1.42±0.16) mg/L in the OLIF group were significantly lower than those in the PLIF group [(18.08±3.84) ng/L, (8.73±5.43) ng/L, (2.04±0.25) mg/L], the differences between the two groups were statistically significant ( P<0.05). Conclusion:Compared with PLIF, OLIF can reduce the amount of intraoperative bleeding, shorten the recovery time, reduce the expression of inflammatory factors and improve the prognosis of patients with DLSS.
