With the emergence of unhealthy dietary structures in people’s life， metabolic associated fatty liver disease （MAFLD） has gradually become the most important chronic liver disease in China， and there is also a gradual increase in the cases of MAFLD-associated liver cancer. Adipose tissue not only has the function of energy storage， but also secretes adipokines that play an important role in the development and progression of MAFLD and its associated liver cancer. Studies on the mechanism of adipokines have provided important help for the prevention and treatment of MAFLD， and a large number of studies have shown that the abnormal secretion of adipokines is associated with MAFLD and plays an important regulatory role in the development and progression of liver cancer. Adipokines are not only regulated at the gene level， but they can also interact with genes through specific pathways to co-regulate pathophysiological processes such as inflammation， metabolism， immunity， and cell proliferation in MAFLD and its associated liver cancer. This article reviews the latest studies on the association of adipokines with MAFLD and its associated liver cancer， in order to provide new directions for further research on the pathogenesis of liver cancer.

BACKGROUND:At present,there are some limitations in evaluating the severity of acute spinal cord injury,and a rapid and accurate evaluation method is urgently needed. OBJECTIVE:To analyze the correlation between the expression levels of serum oxidative stress and nerve injury indexes and the severity of the disease in patients with acute spinal cord injury. METHODS:A total of 65 patients were included in the study from August 2020 to May 2022,including 32 patients in the experimental group(acute spinal cord injury)and 33 patients in the control group(simple spinal fracture).American Spinal Injury Association(ASIA)Impairment Scale and neurological function score were evaluated within 8 hours of admission.Meanwhile,serum levels of superoxide dismutase,malondialdehyde,glutathione,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase were detected and compared between the two groups.The correlation between the expression levels of the above serological indicators in serum and ASIA impairment grade and AISA neural function score was analyzed. RESULTS AND CONCLUSION:The average serum levels of superoxide dismutase and glutathione in the experimental group were significantly lower than those of the control group(P<0.001),while the average serum levels of malondialdehyde,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase in the experimental group were higher than those of the control group(P<0.01).The serum levels of superoxide dismutase and glutathione in the experimental group were positively correlated with the damage grade of AISA(r=0.862 4,0.849 3,P<0.01),while the serum levels of malondialdehyde,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with the damage grade of AISA(r=-0.866 1,-0.638 1,-0.746 6,P<0.001),and the serum level of nitric oxide was not significantly correlated with the damage grade of AISA(r=-0.177 5,P>0.05).The serum level of glutathione in the experimental group was positively correlated with AISA sensory function scores(r=0.569 9,P<0.001),while the serum levels of malondialdehyde,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with AISA sensory function scores(r=-0.574 1,-0.099 2,-0.708 6,P<0.05),and the serum levels of superoxide dismutase and nitric oxide were not significantly correlated with AISA sensory function scores(r=0.230 8,-0.376 2,P>0.05).The serum levels of superoxide dismutase and glutathione in the experimental group were positively correlated with ASIA motor function scores(r=0.380,0.524 7,P<0.05);the serum levels of malondialdehyde,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with AISA motor function scores(r=-0.577 9,-0.452 2,-0.662 8,P<0.05);and the level of nitric oxide had no significant correlation with AISA motor function scores(r=-0.049 7,P>0.05).To conclude,the serum levels of superoxide dismutase,malondialdehyde,glutathione,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase in serum of patients with acute spinal cord injury are significantly correlated with ASIA impairment grade and ASIA neural function score,which could be used as biomarkers for early clinical assessment of disease severity.

Purpose To investigate the risk factors of severe hypocalcemia after ultrasound-guided thermal ablation for secondary hyperparathyroidism.Materials and Methods A retrospective case-control study was used to study 91 patients with uremia complicated with secondary hyperparathyroidism in the First People's Hospital of Yulin from May 2019 to May 2023.All patients underwent ultrasound-guided thermal ablation and were divided into severe hypocalcemia group(SH)and non-SH group according to postoperative blood calcium levels.The difference of clinical data between the two groups was compared,and the independent risk factors of SH were investigated by multivariate Logistic regression analysis.Results A total of 317 glands were ablated in 49 cases of microwave ablation and 42 cases of radiofrequency ablation.SH occurred in 57 cases(62.64%)after ablation.The comparison of clinical data between the two groups showed that there were significant differences in the preoperative intact parathyroid hormone(iPTH),decline rate of iPTH 1 d,preoperative serum alkaline phosphatase,the proportion of parathyroid glands≥4 and the total gland volume between the two groups(all P<0.05).Receiver operating characteristic curve analysis was used to obtain the best cut-off point of iPTH 1 d decline rate,the result was 74.59%,the area under the curve was 0.866(95%CI 0.787-0.945)(P<0.05),the sensitivity was 84.2%,and the specificity was 78.1%.Multivariate Logistic regression analysis showed that preoperative alkaline phosphatase(OR=1.015,95%CI 1.005-1.025,P=0.030)and decline rate of iPTH 1 d≥74.59%(OR=30.423,95%CI 5.938-155.858,P<0.001)and parathyroid glands≥4(OR=4.355,95%CI 1.027-18.469,P=0.046)were independent risk factors for postoperative SH(all P<0.05).Conclusion Preoperative alkaline phosphatase and decline rate of iPTH 1 d≥74.59%and the number of parathyroid glands≥4 are independent risk factors for SH after thermal ablation.

Objective To observe the risk factors of recurrence after ultrasound-guided thermal ablation for treating uremia secondary hyperparathyroidism(SHPT).Methods Totally 59 patients with uremia SHPT who underwent ultrasound-guided thermal ablation were enrolled,including 23 cases with(relapse group)and 36 without SHPT recurrence(non relapsed group).Clinical data were compared between groups,univariate and multivariate logistic regression analysis were performed to screen independent risk factors of SHPT recurrence.Results There were significant differences of serum free thyroxine(FT4),urea,intact parathyroid hormone(iPTH)1 day after ablation,1 day decrease rate of iPTH,the maximum diameter of the largest nodule,ablation time,total ablation energy,energy to volume ratio and the proportion of 1 day decrease rate of iPTH≤90%between groups(all P＜0.05).Higher urea,lower energy to volume ratio and 1 day decrease rate of iPTH≤90%were all independent risk factors of SHPT recurrence(all P＜0.05).Conclusion Higher urea,lower energy to volume ratio and 1 day decrease rate of iPTH≤90%were independent risk factors of recurrence after ultrasound-guided thermal ablation for treating uremia SHPT.

Objective: : EID3 (EP300-interacting inhibitor of differentiation) was identified as a novel member of EID family and plays a pivotal role in colorectal cancer development. However, its role in glioma remained elusive. In current study, we identified EID3 as a novel oncogenic molecule in human glioma and is critical for glioma cell survival, proliferation and invasion. Methods: : A total of five patients with glioma were recruited in present study and fresh glioma samples were removed from patients. Four weeks old male non-obese diabetic severe combined immune deficiency (NOD/SCID) mice were used as transplant recipient models. The subcutaneous tumor size was calculated and recorded every week with vernier caliper. EID3 and AMP-activated protein kinase α1 (AMPKα1) expression levels were confirmed by real-time polymerase chain reaction and Western blot assays. Colony formation assays were performed to evaluate cell proliferation. Methyl thiazolyl tetrazolium (MTT) assays were performed for cell viability assessment. Trypan blue staining approach was applied for cell death assessment. Cell Apoptosis DNA ELISA Detection Kit was used for apoptosis assessment. Results: : EID3 was preferentially expressed in glioma tissues/cells, while undetectable in astrocytes, neuronal cells, or normal brain tissues. EID3 knocking down significantly hindered glioma cell proliferation and invasion, as well as induced reduction of cell viability, apoptosis and cell death. EID3 knocking down also greatly inhibited tumor growth in SCID mice. Knocking down of AMPKα1 could effectively rescue glioma cells from apoptosis and cell death caused by EID3 absence, indicating that AMPKα1 acted as a key downstream regulator of EID3 and mediated suppression effects caused by EID3 knocking down inhibition. These findings were confirmed in glioma cells generated patient-derived xenograft models. AMPKα1 protein levels were affected by MG132 treatment in glioma, which suggested EID3 might down regulate AMPKα1 through protein degradation. Conclusion : Collectively, our study demonstrated that EID3 promoted glioma cell proliferation and survival by inhibiting AMPKα1 expression. Targeting EID3 might represent a promising strategy for treating glioma.

Objective:To investigate the effect of preoperative hemoglobin (Hb) level on the risk of developing acute kidney injury (AKI) after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI).Methods:A retrospective study was conducted. The hospitalized patients diagnosed with AMI who underwent PCI from May 2015 to May 2020 in the department of cardiology in the Affiliated Changzhou No.2 People's Hospital of Nanjing Medical University were enrolled. According to the serum creatinine (SCr) level before and after interventional therapy, the patients were divided into an AKI group and a non-AKI group. The difference in patients' Hb levels between the AKI and non-AKI groups was compared. Univariate and multivariate Logistic regression analyses were used to analyze the effects of Hb levels on the risk of AKI after interventional therapy in patients with AMI. Kaplan-Meier survival curve was used to evaluate the effects of Hb levels on patients with AMI in all-cause death in the hospital.Results:A total of 922 AMI patients were enrolled in this study, of which 165 patients (17.9%) developed AKI. Compared with the non-AKI group, female patients in the AKI group had a higher proportion [35.8% (59/165) vs. 26.9% (204/757)], older (age: 69.78±14.56 vs. 66.61±13.44), with a lower rate of smoking [42.4% (70/165) vs. 51.7% (391/757)] and a higher prevalence of hypertension [73.3% (121/165) vs. 63.5% (481/757)], however, the patients in AKI group also had a worse cardiac function [the proportion of Killip grade 3 or above was higher: 33.9% (56/165) vs. 13.9% (105/757)], lower Hb level (g/L: 127.61±22.18 vs. 132.79±19.45), and there were less patients using angiotensin converting enzyme inhibitor/angiotensin Ⅱreceptor blocker [ACEI/ARB, 60.0% (99/165) vs. 74.5% (564/757)] and more patients using diuretics [24.8% (41/165) vs. 17.7% (134/757)] in AKI group, the differences were statistically significant (all P < 0.05). Compared with non-AKI group, patients in AKI group had a longer operation time [operation time > 60 minutes: 4.2% (7/165) vs. 1.5% (11/757)] and received more contrast media during the operative procedure [contrast media > 100 mL: 16.4% (27/165) vs. 3.6% (27/757)], the individuals had a higher rate of intra-operative hypotension [16.4% (27/165) vs. 8.2% (62/757)], and more patients were implanted more than 2 stents [8.5% (14/165) vs. 3.6% (27/757), all P < 0.05]. Univariate Logistic regression analysis suggested that each 1 g/L increase in preoperative Hb level was associated with a 1.2% decrease in the risk of postoperative AKI [odds ratio ( OR) = 0.988, 95% confidence interval (95% CI) was 0.980-0.996, P = 0.003]. Meanwhile, for every 1 standard deviation increase in preoperative Hb level, the risk of postoperative AKI decreased by 22.1% ( OR = 0.779, 95% CI was 0.661-0.918, P = 0.003). The patients were divided into low, medium and high concentration groups according to Hb levels (Hb levels were < 110 g/L, 110-150 g/L, ≥ 150 g/L, respectively), and multivariate Logistic regression analysis showed that the risk of AKI was significantly reduced in the high concentration group compared with that in the low concentration group ( OR = 0.463, 95% CI was 0.241-0.888, P = 0.020). The Kaplan-Meier survival curve analysis indicated that the short term survival after coronary intervention in AMI patients with low Hb concentration was significantly lower than that in patients with medium and high Hb concentration (Log-Rank: χ2= 23.215, P < 0.001). Conclusions:Preoperative lower Hb level is an independent risk factor for postoperative AKI in AMI patients. AMI patients with lower Hb levels have an increased risk of all-cause mortality within 1 month after AMI.
