ObjectiveTo perform metabolic associated fatty liver disease (MAFLD) screening among individuals attending community health institutions, to identify the patients at a low, moderate or high risk of advanced liver fibrosis based on fibrosis-4 index (FIB-4) and liver stiffness measurement (LSM) measured by liver transient elastography, and to implement stratified management. MethodsA cross-sectional study was conducted among 630 individuals attending Beijing Baizhifang Community Health Service Center from January to July 2024, and they were divided into MAFLD group and non-MAFLD group. According to body mass index (BMI), the MAFLD group was further divided into lean MAFLD group (BMI<23 kg/m2) and non-lean MAFLD group (BMI≥23 kg/m2). The above groups were compared in terms of demographic features, laboratory markers, hepatic steatosis, and LSM. Fibrosis risk stratification was performed for MAFLD patients based on FIB-4 and LSM, and a closed-loop management system involving referral to tertiary hospitals and follow-up at community health institutions was implemented. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsThere were 445 individuals (70.6%) in the MAFLD group and 185 individuals (29.4%) in the non-MAFLD group. Compared with the non-MAFLD group, the MAFLD group had a significantly lower proportion of male individuals (χ2=4.299, P<0.05), a significant reduction in the level of high-density lipoprotein cholesterol (Z=3.484, P<0.05), and significant increases in body weight (Z=-7.366, P<0.05), BMI (Z=-9.740, P<0.05), waist circumference (Z=-6.397, P<0.05), hip circumference (Z=-6.935, P<0.05), alanine aminotransferase (ALT) (Z=-2.765, P<0.05), fasting blood glucose (Z=-3.646, P<0.05), triglyceride (TG) (Z=-6.569, P<0.05), total cholesterol (Z=-2.033, P<0.05), low-density lipoprotein cholesterol (Z=-2.935, P<0.05), controlled attenuation parameter (CAP) (Z=-19.784, P<0.05), and LSM (Z=-5.703, P<0.05). Within the MAFLD group, there were 124 individuals (27.9%) in the lean MAFLD group and 321 individuals (72.1%) in the non-lean MAFLD group. Compared with the non-lean MAFLD group, the lean MAFLD group had significantly lower body weight (Z=-12.414, P<0.05), BMI (Z=-16.363, P<0.05), waist circumference (Z=-7.733, P<0.05), hip circumference (Z=-8.595, P<0.05), ALT (Z=-2.835, P<0.05), aspartate aminotransferase (Z=-1.972, P<0.05), TG (Z=-2.407, P<0.05), CAP (Z=-4.429, P<0.05), degree of steatosis (χ2=16.588, P<0.05), and LSM (Z=-3.908, P<0.05). Based on the results of FIB-4 and LSM, 76 patients at a moderate or high risk of liver fibrosis should be referred to a higher-level hospital for further management. ConclusionThe detection rate of MAFLD reaches 70.6% among the individuals attending community health institutions, among whom 76 (17.1%) should be referred to a higher-level hospital. Establishing a liver fibrosis risk stratification and management system based on FIB-4 and LSM among MAFLD individuals in communities provides a practical pathway for chronic disease management and referral system construction in community health institutions.

This article reports a case of a male patient, aged 60 years, who developed pyrrolizidine alkaloid-induced hepatic sinusoidal obstruction syndrome (PA-HSOS) due to ingestion of Gynura segetum (Lour.) Merr. The patient presented with ascites and abnormal liver function, and a confirmed diagnosis was made based on radiological examination and liver biopsy. Since the patient was allergic to low-molecular-weight heparin and had no response to supportive therapy, low-dose defibrotide was administered as rescue treatment. After treatment, the patient achieved rapid regression of ascites and recovery of liver function, and liver biopsy reexamination showed alleviation of sinusoidal congestion and hepatocyte regeneration. Self-resolving conjunctival hemorrhage occurred during treatment. This case suggests that for patients with contraindications to standard anticoagulation therapy or those showing no response to such treatment, low-dose defibrotide may be used as an effective and relatively safe alternative treatment regimen.

Epilepsy is a chronic neurological disorder affecting ~65 million individuals worldwide. Abnormal synaptic plasticity is one of the most important pathological features of this condition. We investigated how ubiquitin-specific peptidase 47 (USP47) influences synaptic plasticity and its link to epilepsy. We found that USP47 enhanced excitatory postsynaptic transmission and increased the density of total dendritic spines and the proportion of mature dendritic spines. Furthermore, USP47 inhibited the degradation of the ubiquitinated α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) subunit glutamate receptor 1 (GluR1), which is associated with synaptic plasticity. In addition, elevated levels of USP47 were found in epileptic mice, and USP47 knockdown reduced the frequency and duration of seizure-like events and alleviated epileptic seizures. To summarize, we present a new mechanism whereby USP47 regulates excitatory postsynaptic plasticity through the inhibition of ubiquitinated GluR1 degradation. Modulating USP47 may offer a potential approach for controlling seizures and modifying disease progression in future therapeutic strategies.

ObjectiveTo identify the patients with metabolic dysfunction-associated fatty liver disease (MAFLD) among the health check-up population, and to perform stratified management of patients with the low, medium, and high risk of advanced fibrosis based on noninvasive fibrosis scores. MethodsA cross-sectional study was conducted among 3 125 individuals who underwent physical examination in Beijing Physical Examination Center from December 2017 to December 2019, and they were divided into MAFLD group with 1 068 individuals and non-MAFLD group with 2 057 individuals. According to BMI, the MAFLD group was further divided into lean MAFLD group (125 individuals with BMI<24 kg/m2) and non-lean MAFLD group (943 individuals with BMI≥24 kg/m2). Indicators including demographic data, past history, laboratory examination, and liver ultrasound were compared between groups. Fibrosis-4 (FIB-4) score, NAFLD fibrosis score (NFS), aspartate aminotransferase-to-platelet ratio index (APRI), and BARD score were calculated for the patients in the MAFLD group to assess the risk of advanced fibrosis. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. A logistic regression analysis was used to investigate the influence of each indicator in MAFLD. ResultsCompared with the non-MAFLD group, the MAFLD group had significantly higher age (Z=-9.758, P<0.05), proportion of male patients (χ2=137.555, P<0.05), and levels of body weight (Z=-27.987, P<0.05), BMI (Z=-32.714, P<0.05), waist circumference (Z=-31.805, P<0.05), hip circumference (Z=-26.342, P<0.05), waist-hip ratio (Z=-28.554, P<0.05), alanine aminotransferase (ALT) (Z=-25.820, P<0.05), aspartate aminotransferase (AST) (Z=-16.894, P<0.05), gamma-glutamyl transpeptidase (GGT) (Z=-25.069, P<0.05), alkaline phosphatase (Z=-12.533, P<0.05), triglyceride (Z=-27.559), total cholesterol (Z=-7.833, P<0.05), low-density lipoprotein cholesterol (LDL-C) (Z=-8.222, P<0.05), and uric acid (UA) (Z=-20.024, P<0.05), as well as a significantly higher proportion of patients with metabolic syndrome (MetS) (χ2=578.220, P<0.05), significantly higher prevalence rates of hypertension (χ2=241.694, P<0.05), type 2 diabetes (χ2=796.484, P<0.05), and dyslipidemia (χ2=369.843, P<0.05), and a significant reduction in high-density lipoprotein cholesterol (HDL-C) (Z=23.153, P<0.001). The multivariate logistic regression analysis showed that male sex (odds ratio [OR]=1.45, 95% confidence interval [CI]: 1.203 — 1.737), ALT (OR=1.05, 95%CI: 1.046 — 1.062), LDL-C (OR=1.23, 95%CI: 1.102 — 1.373), and comorbidity with MetS (OR=5.97, 95%CI: 4.876 — 7.316) were independently associated with MAFLD. Compared with the non-lean MAFLD group, the lean MAFLD group had significantly higher age (Z=3.736, P<0.05) and HDL-C (Z=2.679, P<0.05) and significant reductions in the proportion of male patients (χ2=28.970, P<0.05), body weight (Z=-14.230, P<0.05), BMI (Z=-18.188, P<0.05), waist circumference (Z=-13.451, P<0.05), hip circumference (Z=-13.317, P<0.05), ALT (Z=-4.519, P<0.05), AST (Z=-2.258, P<0.05), GGT (Z=-4.592, P<0.05), UA (Z=-4.415, P<0.05), the proportion of patients with moderate or severe fatty liver disease or MetS (χ2=42.564, P<0.05), and the prevalence rates of hypertension (χ2=12.057, P<0.05) and type 2 diabetes (χ2=3.174, P<0.05). Among the patients with MAFLD, 10 patients (0.9%) had an FIB-4 score of >2.67, 4 patients (0.4%) had an NFS score of >0.676, 8 patients (0.7%) had an APRI of >1, and 551 patients (51.6%) had a BARD score of ≥2. ConclusionThere is a relatively high prevalence rate of MAFLD among the health check-up population in Beijing, but with a relatively low number of patients with a high risk of advanced fibrosis, and such patients need to be referred to specialized hospitals for liver diseases.

ObjectiveTo screen for the patients with metabolic dysfunction-associated fatty liver disease (MAFLD) among the physical examination population, to observe the characteristics of MAFLD patients, and to compare the differences in lifestyle between the MAFLD population and the non-MAFLD population. MethodsA cross-sectional study was conducted among 6 206 individuals who underwent physical examination in a physical examination institution in Beijing from December 2015 to December 2019, and according to the new diagnostic criteria for MAFLD, the examination population was divided into MAFLD group and non-MAFLD group. Based on body mass index (BMI), the MAFLD group was further divided into lean MAFLD group (BMI<24 kg/m2) and non-lean MAFLD group (BMI ≥24 kg/m2). Related data were compared between groups, including demographic indicators, education level, work pressure, physical measurement indicators, and lifestyles such as sleep, diet, and exercise. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the chi-square test was used for comparison of categorical data between groups. ResultsOf all individuals in this study, 1 926 (31.1%) had MAFLD and 4 280 (68.9%) did not have MAFLD. Compared with the non-MAFLD group, the MAFLD group had significantly higher age (Z=-14.459, P<0.001), proportion of male patients (χ2=72.004, P<0.001), work pressure (χ2=7.744, P=0.005), body weight (Z=-43.508, P<0.001), BMI (Z=-47.621, P<0.001), waist circumference (Z=-48.515, P<0.001), hip circumference (Z=-42.121, P<0.001), and waist-hip ratio (Z=-43.535, P<0.001), as well as a significantly lower education level (χ2=33.583, P<0.001). In terms of behavior, the MAFLD group had a significantly shorter sleep time (χ2=5.820, P=0.016) and a significantly faster eating speed (χ2=74.476, P<0.001). In terms of diet, the patients in the MAFLD group consumed more high-sodium, high-sugar, and high-calorie diets (χ2=42.667, P<0.001) and low-fiber diet (χ2=4.367, P=0.008). In terms of exercise, the MAFLD group had a significantly higher proportion of patients without exercise habits (χ2=10.278, P=0.001). Further analysis showed that there were 202 individuals (10.5%) in the lean MAFLD group and 1 724 (89.5%) in the non-lean MAFLD group. Compared with the non-lean MAFLD group, the lean MAFLD group had significantly higher age (Z=3.368, P=0.001) and education level (χ2=9.647, P=0.002) and significantly lower proportion of male patients (χ2=27.664, P<0.001), body weight (Z=-18.483, P<0.001), BMI (Z=-23.286, P<0.001), waist circumference (Z=-18.565, P<0.001), and hip circumference (Z=-18.097, P<0.001), and in terms of behavior, the non-lean MAFLD group had a significantly faster eating speed (χ2=4.549, P=0.033). ConclusionThere is a relatively high prevalence rate of MAFLD among the physical examination population in Beijing, with a higher number of people with unhealthy lifestyles compared with the non-MAFLD population.

Objective To investigate the clinical and metabolic factors associated with the development and regression of metabolic dysfunction-associated fatty liver disease(MAFLD)in the physical examination population.Methods A retrospective observational study was conducted on 6 809 individuals who underwent physical examination in a physical examination institution in Beijing from December 2013 to December 2019,with a mean follow-up time of 52.1±13.5 months.According to the new diagnostic criteria for MAFLD,these individuals were divided into MAFLD group and non-MAFLD group,and the two groups were compared in terms of demographic indicators,body measurement indicators,and laboratory indicators at the first(baseline)and last physical examinations.The two-independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data.A Logistic regression analysis was used to investigate the impact of various observation indicators on the development and regression of MAFLD.Results In this study,there were 4 533 individuals(66.6%)in the non-MAFLD group at baseline,among whom 15.6%developed MAFLD at the last physical examination.Compared with the non-MAFLD population,the MAFLD population had significantly higher age(Z=-6.739),number of male patients(χ2=178.534),body weight(Z=-22.302),body mass index(BMI)(Z=-22.818),waist circumference(Z=-23.117),hip circumference(Z=-18.446),systolic blood pressure(SBP)(Z=-13.301),diastolic blood pressure(DBP)(Z=-13.491),fasting blood glucose(FBG)(Z=-11.787),triglyceride(TG)(Z=-16.623),low-density lipoprotein cholesterol(LDL-C)(Z=-10.256),alanine aminotransferase(ALT)(Z=-14.250),aspartate aminotransferase(AST)(Z=-7.481),and proportion of patients with metabolic syndrome(MetS)at baseline(χ2=185.283),and there were more patients with increases in body weight,waist circumference,hip circumference,TG,TC,ALT,and AST at the final physical examination(all P<0.05);these patients had a lower level of HDL-C at baseline(Z=15.416),and there were more patients with a reduction at the last physical examination(P<0.05).There were 2 276 individuals(33.4%)in the MAFLD group at baseline,among whom 23.8%showed regression of MAFLD at the last physical examination.Compared with the population without regression of MAFLD,the population with regression of MAFLD had a significantly younger age(Z=2.185),a significantly higher number of female patients(χ2=0.340),significantly lower levels of body weight(Z=-8.909),BMI(Z=-10.205),waist circumference(Z=-11.183),hip circumference(Z=-7.178),SBP(Z=-3.627),DBP(Z=-3.443),TG(Z=-5.945),ALT(Z=-9.664),and AST(Z=-5.904),and a significantly lower proportion of patients with MetS(χ2=42.082),and there were more patients with reductions in body weight,waist circumference,hip circumference,blood pressure,TG,TC,ALT,and AST at the final physical examination(all P<0.05);these patients had a higher level of HDL-C at baseline(Z=6.778),and there were more patients with an increase at the last physical examination(P<0.05).The multivariate Logistic regression analysis showed that sex and changes in body weight and HDL-C during physical examination were independently associated with the development and regression of MAFLD(all P<0.05).Conclusion There is a relatively high prevalence rate of MAFLD among the physical examination population in Beijing,with a higher proportion of male patients.There are significant metabolic disorders and liver function abnormalities,and changes in body weight and HDL-C are the most important predictive indicators for the development and regression of MAFLD.
