Changing trend of the disease burden of liver cirrhosis in China from 1990 to 2019 / 临床肝胆病杂志

ObjectiveTo investigate the prevalence of liver cirrhosis and the changing trend of the disease burden of liver cirrhosis in the Chinese population from 1990 to 2019， and to provide a data reference for formulating the prevention and treatment strategies for liver cirrhosis in China. MethodsThe Global Burden of Disease Study 2019 was used to collect the data on the incidence rate， mortality rate， disability-adjusted life years （DALY）， years of life lost （YLL）， and years lived with disability （YLD） of liver cirrhosis. The Joinpoint regression model was used to analyze the changing trend of disease burden； the age-period-cohort （APC） model was used to evaluate age， period， and cohort effects； R software BAPC package was used to predict future changes in disease burden. ResultsFrom 1990 to 2019 in China， there were increases in the numbers of liver cirrhosis cases and prevalent cases in the general population， as well as in the male and female populations， while there was a reduction in the number of deaths. From 1990 to 2019， the standardized incidence rate， standardized prevalence rate， and standardized mortality rate of liver cirrhosis in the Chinese population showed a downward trend， with a mean annual reduction of 0.62% （95% confidence interval ［CI］： -0.74% to -0.50%， t=9.99， P<0.001）， 0.44% （95%CI： -0.53% to -0.35%， t=13.18， P<0.001）， and 3.02% （95%CI： -3.12% to -2.93%， t=7.58， P<0.001）， respectively. From 1990 to 2019， the standardized DALY， YLL， and YLD rates of liver cirrhosis in the Chinese population also showed a downward trend， with a mean annual reduction of 3.27% （95%CI： -3.37% to -3.18%， t=6.22， P<0.001）， 3.32% （95%CI： -3.42% to -3.22%， t=9.31， P<0.001）， and 1.42% （95%CI： -1.49% to -1.34%， t=4.93， P<0.001）， respectively. From 1990 to 2019， the incidence rate of liver cirrhosis in the Chinese population first increased and then decreased with age， while the mortality rate showed an increasing trend， and the risks of disease onset and death showed a decreasing trend with time and birth cohort. The predictive model showed that the standardized incidence rate， prevalence rate， mortality rate， and DALY rate of liver cirrhosis in China will show a decreasing trend from 2020 to 2030. Alcohol was the most important risk factor for both male and female populations， followed by medication. ConclusionThe disease burden of liver cirrhosis in China shows a decreasing trend from 1990 to 2019， with sex and age differences， especially in the middle-aged male population. Effective measures should be taken for intervention.

Role of Akkermansia muciniphila in nonalcoholic fatty liver disease / 临床肝胆病杂志

Nonalcoholic fatty liver disease （NAFLD） has become the most common chronic liver disease in the world， and it is also one of the main causes of liver cirrhosis and hepatocellular carcinoma， so it is particularly important to curb the development and progression of NAFLD in a timely manner. However， due to its complex pathogeneses， there are currently no effective methods for radical treatment. As a new generation of probiotics， Akkermansia muciniphila （Akk bacteria） can improve metabolic disorders of the body， and more and more studies have shown that Akk bacteria have a potential therapeutic effect on metabolic diseases， especially NAFLD. Therefore， this article briefly reviews the mechanism of action of Akk bacteria in NAFLD， in order to provide new ideas for improving the treatment of NAFLD and creating new therapies.

Long-term auditory monitoring in children with Alport syndrome based on different degrees of renal injury / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate long-term auditory changes and characteristics of Alport syndrome（AS） patients with different degrees of renal injury. Methods:Retrospectively analyzing clinical data of patients diagnosed AS from January 2007 to September 2022, including renal pathology, genetic detection and hearing examination. A long-term follow-up focusing on hearing and renal function was conducted. Results:This study included 70 AS patients, of which 33（25 males, 8 females, aged 3.4-27.8 years） were followed up, resulting in a loss rate of 52.9%.The follow-up period ranged from 1.1to 15.8 years, with 16 patients followed-up for over 10 years. During the follow-up, 10 patients presenting with hearing abnormalities at the time of diagnosis of AS had progressive hearing loss, and 3 patients with new hearing abnormalities were followed up, which appeared at 5-6 years of disease course. All of which were sensorineural deafness. While only 3 patients with hearing abnormalities among 13 patients received hearing aid intervention. Of these patients,7 developed end-stage renal disease（ESRD）, predominantly males （6/7）. The rate of long-term hearing loss was significantly different between ESRD group and non-ESRD group（P=0.013）. There was no correlation between the progression of renal disease and long-term hearing level（P>0.05）. kidney biopsies from 28 patients revealed varying degrees of podocyte lesion and uneven thickness of basement membrane. The severity of podocyte lesion was correlated with the rate of long-term hearing loss（P=0.048）, and there was no correlation with the severity of hearing loss（P>0.05）. Among 11 cases, theCOL4A5mutationwas most common （8 out of 11）, but there was no significant correlation between the mutation type and hearing phenotype（P>0.05）. Conclusion:AS patients exhibit progressive hearing loss with significant heterogeneity over the long-term.. THearing loss is more likely to occur 5-6 years into the disease course. Hearing abnormalities are closely related to renal disease status, kidney tissue pathology, and gene mutations, emphasizing the need for vigilant long-term hearing follow-up and early intervention.

TRIB3 promotes pulmonary fibrosis through inhibiting SLUG degradation by physically interacting with MDM2

Pulmonary fibrosis (PF) is the pathological structure of incurable fibroproliferative lung diseases that are attributed to the repeated lung injury-caused failure of lung alveolar regeneration (LAR). Here, we report that repetitive lung damage results in a progressive accumulation of the transcriptional repressor SLUG in alveolar epithelial type II cells (AEC2s). The abnormal increased SLUG inhibits AEC2s from self-renewal and differentiation into alveolar epithelial type I cells (AEC1s). We found that the elevated SLUG represses the expression of the phosphate transporter SLC34A2 in AEC2s, which reduces intracellular phosphate and represses the phosphorylation of JNK and P38 MAPK, two critical kinases supporting LAR, leading to LAR failure. TRIB3, a stress sensor, interacts with the E3 ligase MDM2 to suppress SLUG degradation in AEC2s by impeding MDM2-catalyzed SLUG ubiquitination. Targeting SLUG degradation by disturbing the TRIB3/MDM2 interaction using a new synthetic staple peptide restores LAR capacity and exhibits potent therapeutic efficacy against experimental PF. Our study reveals a mechanism of the TRIB3-MDM2-SLUG-SLC34A2 axis causing the LAR failure in PF, which confers a potential strategy for treating patients with fibroproliferative lung diseases.

IgD multiple myeloma: report of 1 case and review of literature / 白血病·淋巴瘤

Objective:To investigate the clinical features of IgD multiple myeloma (MM) and the effect and prognosis of daratumumab-based combination therapy.Methods:The clinicopathological data of a IgD MM patient with disease progression and extramedullary infiltration treated with daratumumab in the Affiliated Hospital of Qingdao University in December 2019 were retrospectively analyzed.Results:The 74-year-old woman was diagnosed as IgD MM by bone marrow aspiration and immunofixation electrophoresis. The patient was given VD (bortezomib, dexamethasone), RD (lenalidomide, dexamethasone) and ID (ixazomib, dexamethasone) regimens. In June 2020, the patient developed multiple subcutaneous nodules, and she was assessed as progressive disease with extensive extramedullary infiltration. After treated with daratumumab-PAD (liposomal doxorubicin, bortezomib, dexamethasone) regimen, the patient's subcutaneous nodules were significantly reduced and partially disappeared, and the general condition was significantly improved. But the patient was in a cachexia state and finally died of the irregular treatment and disease progression.Conclusions:IgD MM has a low incidence and a short survival period, and there is no uniform standard treatment. The early application of daratumumab combined with proteasome inhibitors, immunomodulators, cytotoxic drugs and hematopoietic stem cell transplantation may improve the overall survival of patients.

The cell cycle inhibitor P21 promotes the development of pulmonary fibrosis by suppressing lung alveolar regeneration

The cell cycle inhibitor P21 has been implicated in cell senescence and plays an important role in the injury-repair process following lung injury. Pulmonary fibrosis (PF) is a fibrotic lung disorder characterized by cell senescence in lung alveolar epithelial cells. In this study, we report that P21 expression was increased in alveolar epithelial type 2 cells (AEC2s) in a time-dependent manner following multiple bleomycin-induced PF. Repeated injury of AEC2s resulted in telomere shortening and triggered P21-dependent cell senescence. AEC2s with elevated expression of P21 lost their self-renewal and differentiation abilities. In particular, elevated P21 not only induced cell cycle arrest in AEC2s but also bound to P300 and β-catenin and inhibited AEC2 differentiation by disturbing the P300-β-catenin interaction. Meanwhile, senescent AEC2s triggered myofibroblast activation by releasing profibrotic cytokines. Knockdown of P21 restored AEC2-mediated lung alveolar regeneration in mice with chronic PF. The results of our study reveal a mechanism of P21-mediated lung regeneration failure during PF development, which suggests a potential strategy for the treatment of fibrotic lung diseases.

Studies on the mechanism of inhibitory effect of lithium chloride on the proliferation of human Tenon capsule fibroblasts / 中华实验眼科杂志

Objective:To investigate the effect of lithium chloride (LiCl) on the gap junctional intercellular communication (GJIC) in human Tenon capsule fibroblasts (HTFs) and its underlying mechanism.Methods:The Tenon capsule tissue of a patient who underwent strabismus surgery in Dezhou People's Hospital in April 2019 was collected and cut into tissue blocks of dimensions 1 mm×1 mm×1 mm.Primary culture and subculture were carried out, and the 4th-generation HTFs were taken for experiment.HTFs were divided into the control group and LiCl treatment group and were cultured with cell medium without or with 80 mmol/L LiCl for another 48 hours according to grouping.The cell scratch and dye labeling technique were used to label the coupling index and evaluate the GJIC function.The expression and localization of Cx43 in HTFs were detected by immunofluorescence staining.The expression levels of Cx43 mRNA and protein were detected by real-time fluorescence quantitative PCR and Western blot, respectively.The study protocol was approved by an Ethics Committee of Dezhou People's Hospital (No.2019-023). Written informed consent was obtained from the subject.Results:The cultured spindle-shaped HTFs grew adhering to the wall showing radial monolayer or vortexlike, and the cytoplasm was vimentin positive.Results of dye tracer experiment of cell scratch showed that the cell coupling index of LiCl treatment group was 9.04±0.53, which was significantly higher than 4.94±0.39 of the control group ( t=-18.79, P<0.01). Immunofluorescence staining showed that the Cx43 fluorescence was dotted in the cell membrane between adjacent cells in the control group, and Cx43 staining was obviously enhanced in the LiCl treatment group.The results of real-time fluorescence quantitative PCR showed that with relative expression level of Cx43 mRNA in the control group set to 1, the relative expression level of Cx43 in the LiCl treatment group was significantly increased to 1.97±0.23, showing a statistical significance between them ( t=-14.426, P<0.01). Western blot showed that the relative expression level of Cx43 protein was 0.871±0.057 in the LiCl treatment group, which was significantly higher than 0.446±0.028 in the control group ( t=-11.682, P<0.01). Conclusions:LiCl can enhance the GJIC function between HTFs by upregulating the expression levels of Cx43 mRNA and protein, suggesting that the enhanced GJIC function by LiCl may be one of the mechanisms of its inhibition on HTFs proliferation.
