AIM:To investigate the effects of electroacupuncture at the Taiyang on refractive parameters and the expression of β-catenin and integrin β1 in the ciliary body of mice with form-deprivation myopia(FDM).METHODS:A total of 48 3-week-old healthy C57BL/6J mice were randomly divided into 4 groups: normal control(NC), FDM group, sham acupuncture(sham), and electroacupuncture at Taiyang acupoint(Taiyang), with 12 mice in each group. Mice in the FDM, sham, and Taiyang groups, wore translucent custom-made eye masks on the right eye to induce myopia. The Taiyang group received electroacupuncture stimulation at the Taiyang acupoint, while the sham group underwent non-penetrating stimulation with a blunt wooden stick. No intervention was performed on the NC group. Refraction and axial length were measured by infrared autorefractor and optical coherence tomography(OCT)before modeling and at 4 wk after modeling. The expression levels of β-catenin and integrin β1 in the ciliary body of mice at 4 wk after modeling were detected using quantitative real-time PCR(qPCR)and Western blotting(WB).RESULTS:After modeling for 4 wk, compared with the NC group, the FDM and sham groups showed significantly decreased refractive power(both P<0.05), elongated axial length(both P<0.05), and increased β-catenin and integrin β1 expression. Compared with the FDM and sham groups, the Taiyang group showed significantly increased refractive power(both P<0.05), shortened axial length(both P<0.05), and decreased β-catenin and integrin β1 expression.CONCLUSION:Electroacupuncture stimulation at the Taiyang acupoint effectively delayed the progression of myopia in FDM mice, and this effect may be partially mediated through modulating the expression of β-catenin and integrin β1 in the ciliary body.

OBJECTIVE: To investigate the current status of long-term quality of life in patients with severe acute pancreatitis (SAP) who have been cured and discharged, and to analyze the influencing factors affecting long-term quality of life in SAP cured patients after discharge. METHODS: A retrospective collection was conducted. Patients who were received standardized treatment before being cured and discharged from the hospital admitted to the first department of critical care medcine of the Second Affiliated Hospital of Anhui Medical University from January 2017 to December 2023 were enrolled. According to the 36-item short form health survey scale (SF-36) score, patients were divided into high score group (high quality of life, the top 50% of patients with total SF-36 score) and low score group (low quality of life, the bottom 50% of patients with total SF-36 score). The gender, age, history of hypertension and diabetes, etiology of pancreatitis, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), CT severity index (CTSI), laboratory indicators such as C-reactive protein (CRP), procalcitonin (PCT), blood glucose, and triglycerides upon admission, use of vasoactive drugs, non-invasive/high-flow ventilation, invasive ventilation, retroperitoneal puncture and drainage, open pancreatic surgery treatment and secondary infection during hospitalization were collected, as well as the retention of abdominal drainage tubes at discharge from hospital. Distribute follow-up questionnaires or telephone follow-up surveys through WeChat and Question Star programs to investigate the pancreatic secretion function, chronic abdominal pain, and recurrence of pancreatitis of patients after discharge. Multivariable Logistic regression was used to analyze the relevant factors affecting the long-term quality of life of cured patients with SAP. RESULTS: A total of 86 patients were ultimately enrolled. There were 43 patients in both the high and low score groups. Among 86 patients, 20 experienced acute pancreatitis recurrence, with a recurrence rate of 23.26%. Twenty-two (25.58%) experienced chronic abdominal pain after discharge, and 5 patients (5.81%) needed medication to relieve pain. Thirty-three patients (38.37%) had pancreatic exocrine dysfunction after discharge, characterized by abdominal distension, constipation or diarrhea. Twenty-two patients (25.58%) suffered from pancreatic endocrine dysfunction, and were diagnosed with diabetes. Univariate analysis showed that compared with the high score group, the low score group had more patients with hypertension, initial renal dysfunction, initial severe metabolic acidosis, initial serum calcium < 2.0 mmol/L, blood glucose > 11.1 mmol/L and cultured Gram positive bacteria (from blood/body fluid/pancreatic necrotic tissue) during treatment (48.84% vs. 16.28%, 60.47% vs. 32.56%, 18.60% vs. 4.65%, 88.37% vs. 62.79%, 55.81% vs. 30.23%, 34.88% vs. 13.95%), had higher CTSI score (6.60±1.61 vs. 5.77±1.32), lower hemoglobin level at discharge (g/L: 102.30±18.78 vs. 110.72±16.68), and a lower proportion of etiological interventions after discharge (34.88% vs. 67.44%), the differences were statistically significant (all P < 0.05). Multivariate Logistic regression analysis showed that hypertension [odds ratio (OR) = 4.814, 95% confidence interval (95%CI) was 1.196-19.378], initial serum calcium < 2.0 mmol/L (OR = 6.688, 95%CI was 1.321-33.873) and initial blood glucose > 11.1 mmol/L (OR = 6.473, 95%CI was 1.399-29.950) were risk factors for long-term quality of life in cured SAP patients (all P < 0.05), while post discharge prophylactic intervention was a protective factor for long-term quality of life (OR = 0.092, 95%CI was 0.020-0.425, P < 0.01). CONCLUSIONS Cured SAP patients have varying degrees of impaired secretion function and the possibility of recurrence of acute pancreatitis. Hypertension, initial serum calcium < 2.0 mmol/L and blood glucose > 11.1 mmol/L are independent influencing factors for low long-term quality of life in cured SAP patients. Prevention and intervention targeting the etiology of pancreatitis after discharge can improve the long-term quality of life of cured SAP patients.

Objective : To investigate the effects of branched-chain amino acid(BCAA) on the differentiation of 3T3-L1 preadipocytes and its potential mechanism. Methods : 3T3-L1 preadipocytes were divided into the Control, differentiation medium(DM), low-concentration BCAA, and high-concentration BCAA groups. A CCK-8 assay was utilized to evaluate pre-adipocyte survival under various BCAA concentrations. Oil-red O staining was used to observe the formation of lipid droplets in adipocytes. Intracellular triglyceride(TG) and total cholesterol(TC) were detected by enzymatic method. RT-qPCR and Western blot were used to detect the mRNA and protein expression of Stat3 and adipocyte differentiation-related genes. Results : CCK-8 results showed that the viability of 3T3-L1 cells was not affected when the BCAA concentration was ≤ 10 mmol/L. Compared with the DM group, the low-concentration BCAA groups(0.5 and 1.0 mmol/L) had significantly larger intracellular lipid droplets, increased number of lipid droplets, and elevated levels of the intracellular TC(0.88vs0.68 mmol/g; 0.83vs0.68 mmol/g,P<0.01) and TG(0.77vs0.40 mmol/g; 0.62vs0.40 mmol/g,P<0.01). Nevertheless, the cell differentiation in the high-concentration group(5.0 and 10.0 mmol/L) significantly decreased compared with that in the DM group. Further, levels of PPARγ, C/EBPα, Adiponectin, and FABP4 mRNA and protein expression significantly increased in the low-concentration group, but significantly decreased in the high-concentration group than that in the DM group(P<0.01). In addition, low concentrations of BCAA promoted stat3 phosphorylation, while high concentrations inhibited its phosphorylation(P<0.01). Conclusion BCAA have a dual role in regulating the differentiation of preadipocytes through Stat3, i.e. low concentrations of BCAA induce cell differentiation by promoting Stat3 phosphorylation; whereas high concentrations of BCAA inhibit Stat3 phosphorylation and cell differentiation.

Objective:To analyze the proportion of patients with acute primary angle-closure glaucoma (PACG) after the outbreak of coronavirus disease 2019 (COVID-19) in patients undergoing glaucoma surgery and the factors influencing morbidity.Methods:A cross-sectional study was performed.The cluster sampling method was used to collect 141 glaucoma patients hospitalized for glaucoma surgery after the outbreak of COVID-19 in Xuzhou First People's Hospital from December 16, 2022, to January 16, 2023, and 231 glaucoma patients hospitalized for surgery in the same 1-month period from 2019 to 2020, 2020 to 2021, 2021 to 2022 through the hospital information system.Ninety-two eyes of 92 patients with acute PACG after the outbreak were selected as a study group, and 21 eyes of 21 patients with acute PACG hospitalized during the same 1-month period from 2021 to 2022 were selected as a control group.The proportion of patients with different types of glaucoma during the observation period was analyzed.The proportion of patients with acute PACG and the clinical characteristics of acute PACG were analyzed, including age, sex, visual acuity, intraocular pressure (IOP), and anterior chamber angle status.Epidemiological data such as the use of anti-cold medications, and changes in living habits and moods (including daily water intake and anxiety) of patients after COVID-19 infection were obtained by telephone follow-up.Anxiety levels of patients in the study group were assessed using the Hospital Depression and Anxiety Scale (HADS).The triggering factors of acute PACG attack after the COVID-19 outbreak were analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Xuzhou First People's Hospital (No.xyyll[2023]114).Written informed consent was obtained from each subject.Results:The proportion of acute PACG patients in Xuzhou First People's Hospital within one month after the outbreak in 2022 to 2023 increased significantly compared with the same period in 2021 to 2022, 2020 to 2021 and 2019 to 2020, and the differences were statistically significant ( χ2=31.066, 33.331, 20.804; all at P<0.001).There was no statistical significance in the distribution of the number of eyes with different grades of visual acuity, IOP, the number of eyes with IOP ≥30 mmHg (1 mmHg=0.133 kPa), and the distribution of the number of eyes with different anterior chamber angles between the two groups (all at P>0.05).Patients in the control group had no history of COVID-19 infection or use of cold medicines at disease onset.During disease onset, all 92 (100%) patients in the study group had positive COVID-19 nucleic acid test results, of which 57 (61.96%) patients had a history of oral anti-cold medication use.During the same period, 49 (100%) hospitalized patients with other types of glaucoma had positive COVID-19 nucleic acid test results, of which 20 (40.82%) patients had a history of oral cold medication.There was a statistically significant difference in the proportion of patients taking oral cold drugs between acute PACG and other types of glaucoma in the study group ( χ2=5.764, P=0.016).During the outbreak of COVID-19, the study group reported that the daily water intake had increased to varying degrees than before.In the study group, 76 patients had anxiety, accounting for 82.6%.Multiple linear regression analysis showed that IOP=19.052+ 0.009×daily water intake+ 0.858×HADS score ( R2=0.780), and the standardized coefficients of daily water intake and HADS score were 0.542 and 0.452, respectively.Daily water intake had a greater effect on IOP than HADS score. Conclusions:The proportion of acute PACG patients among hospitalized surgical glaucoma patients increased significantly after the COVID-19 outbreak, which is related to risk factors such as oral anti-cold medications containing vasoconstrictors or antihistamines, increased daily water intake, anxiety and other lifestyle, and mood changes.

Aim To investigate whether SIRT6 overexpression inhibits angiotensin Ⅱ(Ang Ⅱ)-induced cardio-myocyte apoptosis by activating adenosine 5'-monophosphate-activated protein kinase/nuclear factor erythroid 2-related factor 2/heme oxygenase-1(AMPK/Nrf2/HO-1)signaling pathway.Methods The experiment was divided into 4 groups:control group,AngⅡ group,Ang Ⅱ+SIRT6 group,Ang Ⅱ+empty vector(EV)group.The mRNA level of SIRT6 was detected by RT-PCR.The cell activity was measured by MTT assay.The cell apoptosis was analyzed by flow cy-tometry.SIRT6,cardiomyocyte apoptosis related proteins(Bax,cleaved Caspase-3,Bcl-2),DNA damage related pro-teins(γ-H2AX,p-ATM),AMPK/Nrf2/HO-1 signaling pathway related proteins(p-AMPK,Nrf2,HO-1)were measured by Western blot.The reactive oxygen species(ROS)content was determined by DCFH-DA staining.The changes of the above indexes among the groups were observed.Results Compared with control group,the mRNA and protein ex-pression levels of SIRT6 and cell activity were significantly decreased in Ang Ⅱ group.Apoptosis rate,the expressions of Bax,cleaved Caspase-3 were increased,and the expression of Bcl-2 was decreased.The expressions of γ-H2AX and p-ATM were increased,and the expressions of p-AMPK,Nrf2,HO-1 were decreased.The activity of ROS was increased(P＜0.01).Compared with Ang Ⅱ+EV group,the expression of SIRT6 and cell activity were significantly increased in Ang Ⅱ+SIRT6 group.Apoptosis rate,the expressions of Bax and cleaved Caspase-3 were decreased,and the expression of Bcl-2 was increased.The expressions of γ-H2AX and p-ATM were decreased,the expressions of p-AMPK,Nrf2,HO-1 were increased.The activity of ROS was decreased(P＜0.01).Conclusion SIRT6 overexpression inhibits Ang Ⅱ-induced cardiomyocyte apoptosis through activation of AMPK/Nrf2/HO-1 signaling pathway.

BACKGROUND:A previous study by our group found that protein phosphatase 2Cm(PP2Cm)null mice developed significantly fewer symptoms of renal failure relative to wild-type mice,and thus it was speculated that PP2Cm may play an important protective role in the development of renal fibrosis,however,the molecular mechanisms remain undefined. OBJECTIVE:To investigate the effect of the PP2Cm gene on the transcriptome of human renal tubular epithelial cells. METHODS:Cultured human renal tubular epithelial cells were transfected with the PP2Cm gene into human renal tubular epithelial cells using plasmids.The expression of PP2Cm in the cells was detected by fluorescence quantitative PCR assay and western blot assay,and subsequently,cell RNA was separately extracted for transcriptome sequencing to look for differentially expressed genes between transfected and control groups.The resulting differential genes were further subjected to GO analysis and KEGG analysis using bioinformatics methods. RESULTS AND CONCLUSION:There were 796 differentially expressed genes,553 of which were downregulated genes and 243 upregulated genes,in human renal tubular epithelial cells transfected with the PP2Cm gene compared with untransfected blank cells by sequencing analysis.GO analysis results showed that the upregulated genes were significantly enriched in cellular biosynthetic processes,protein translation,intrinsic apoptotic signaling pathways,and so on.The downregulated expressed genes were significantly enriched in endothelial cell proliferation,cell adhesion and other signaling pathways.KEGG analysis results showed that the significantly up-regulated genes were enriched in metabolism-related signaling pathways such as amino acid metabolism and biosynthesis.The downregulated expressed genes were significantly enriched in signaling pathways such as pantothenate and coenzyme A biosynthesis.Our results show that PP2Cm overexpression can affect a number of signaling pathways related to a range of biological processes in renal tubular epithelial cells,which may be important in metabolism-related signaling pathways such as amino acid metabolism and biosynthesis.

Objective:To comprehensively understand the disease burden of liver cirrhosis and other chronic liver diseases caused by alcohol use in China from 1990 to 2019, as well as to predict the trends in disease burden from 2020 to 2030.Methods:The analysis utilized data from the Global Burden of Disease study in 2019 (GBD2019). Key indicators such as incidence rate, mortality rate, disability-adjusted life years (DALY), years of life lost due to premature mortality, and years lived with disability were selected to describe the disease burden of alcohol-related liver cirrhosis and other chronic liver diseases in China from 1990 to 2019. The estimated annual percentage change (EAPC) was used to depict the temporal trends in disease burden. Furthermore, a Bayesian age-period-cohort (BAPC) model was constructed using R software to predict the age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of alcohol-related liver cirrhosis and other chronic liver diseases in China from 2020 to 2030.Results:From 1990 to 2019, the incidence of alcohol-related liver cirrhosis and other chronic liver diseases in China showed an upward trend, with an EAPC of 0.31% (95% CI: 0.10%-0.52%). However, the DALY declined, with an EAPC of -2.81% (95% CI: -2.92% - -2.70%). The ASMR showed a downward trend, with an EAPC of -2.55% (95% CI: -2.66% - -2.45%). The highest incidence of cirrhosis of liver caused by alcohol and other chronic liver diseases was reported in the age group of 35-49 years, while the ASMR increased gradually with age, with a significant rise after the age of 30. The age-standardized DALY rate peaked between the ages of 55 and 64. The disease burden indicators for males were consistently higher than those for females during the same period. According to the predictions of the BAPC model, from 2020 to 2030, the ASIR for cirrhosis of liver caused by alcohol and other chronic liver diseases in the entire population of China was projected to increase from 3.45/100 000 in 2020 to 3.78/100 000 in 2030, a growth of 9.57%. Conversely, the ASMR was expected to decrease from 1.45/100 000 in 2020 to 1.24/100 000 in 2030, a reduction of 14.48%. Conclusions:The disease burden of cirrhosis of liver caused by alcohol and other chronic liver diseases remained serious in China, especially in men and the middle-aged to elderly population. There is a pressing need to prioritize attention and resources towards these groups. Despite the projected decrease in ASMR, the ASIR continued to rise and is expected to persist in its upward trend until 2030.

Objective To study the protective effect of polydatin on lipopolysaccharide-induced injury of human umbilical vein vascular endothelial cells(HUVECs)through the protein Janus kinase 2(JAK2)/signal transducers and activators of transcription 3(STAT3)signaling pathway.Methods HUVECs were cultured in vitro,and 500 ng/ml LPS induced their injury and set as a model group;based on the model group,endothelial cells were inter-vened with different concentrations(10,20,and 40 μmol/L)of polydatin for 24 h,and set as polydatin low concentration group,polydatin medium concentration group,and polydatin high concentration group,respectively;a control group was set as another group.CCK-8,monocyte-endothelial cell adhesion,scratch and Transwell assays were used to detect cell viability,adhesion,migration and invasive ability;ELISA was used to detect interleukin-6(IL-6)and tumor necrosis factor-alpha(TNF-α)levels in the cell supernatant;Western blot was used to detect the expression of proteins related to the JAK2/STAT3 signaling pathway levels of JAK2/STAT3 signaling pathway relat-ed proteins.Results Compared with the control group,the model group showed decreased cell survival(P＜0.01),increased cell adhesion,migration and invasion(P＜0.001,P＜0.05,P＜0.01),increased levels of IL-6 and TNF-α in the cell supernatant(P＜0.001),and increased levels of phosphorylation of JAK2 and STAT3 pro-teins in the cells(P＜0.05).Compared with the model group,LPS damage to cells was attenuated after polydatin intervention,cell survival was increased in polydatin low-,medium-and high-concentration groups(P＜0.05),cell adhesion,migration,and invasion decreased(P＜0.05,P＜0.05,P＜0.001),IL-6 and TNF-α levels in cell supernatants decreased(P＜0.05),and the levels of cellular JAK2 and STAT3 protein phosphorylation lev-els decreased(P＜0.05).Conclusion Polydatin seems to reduce the inflammatory injury of human umbilical vein endothelial cells induced by LPS,reducing the secretion of inflammatory factors,and inhibiting the ability of cell ad-hesion,migration and invasion,which may be related to the down-regulation of JAK2/STAT3 signal pathway by polydatin.
