Objective:To investigate the impact of donor age on early postoperative liver function recovery in liver transplant recipients, as well as the incidence and risk factors for arterial complications following liver transplantation.Methods:A total of 518 patients who underwent liver transplantation at the Organ Transplantation Center of the Affiliated Hospital of Qingdao University between January 2021 and January 2024 were included in the study. Based on donor age, patients were classified into the elderly donor group (≥70 years, n=28) and the non-elderly donor group (<70 years, n=490). Liver function indicators—including aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), and direct bilirubin (DBIL)—were measured on postoperative days 1, 3, 7, and 14. The incidence of arterial complications, including hepatic artery thrombosis and hepatic artery stenosis, was recorded. Recipients were further categorized into the arterial complication group (n=26) and the non-arterial complication group (n=492) based on postoperative outcomes, and clinical characteristics of donors and recipients were compared. Binary logistic regression analysis was conducted to identify risk factors for arterial complications.Rusults:No significant differences were observed in baseline characteristics between the elderly and non-elderly donor groups ( P>0.05). However, the elderly donor group exhibited significantly higher AST, ALT, TBIL, and DBIL levels at all postoperative time points compared to the non-elderly donor group (all P<0.05). Specifically, on postoperative day 1, AST and ALT levels were (1,024.57±256.49) U/L and (756.24±145.89) U/L in the elderly donor group, compared to (895.23±225.19) U/L and (614.85±126.51) U/L in the non-elderly donor group. On day 3, AST and ALT levels were (402.46±71.61) U/L and (423.31±87.44) U/L versus (226.37±66.54) U/L and (256.79±70.25) U/L, respectively. On day 7, AST and ALT levels were (91.78±21.84) U/L and (92.36±21.62) U/L versus (68.41±18.38) U/L and (77.47±18.16) U/L. By day 14, AST and ALT levels were (67.52±10.35) U/L and (72.17±16.28) U/L versus (35.32±9.27) U/L and (48.56±14.10) U/L, respectively ( P<0.05 for all comparisons). For bilirubin indicators, TBIL and DBIL levels in the elderly donor group were also consistently higher than in the non-elderly donor group. On day 1, TBIL and DBIL were (95.76±21.93) μmol/L and (64.22±15.07) μmol/L, compared to (77.59±20.48) μmol/L and (51.18±12.96) μmol/L. By day 14, TBIL and DBIL levels had decreased to (41.26±8.30) μmol/L and (32.45±6.21) μmol/L, compared to (28.39±7.15) μmol/L and (20.58±5.04) μmol/L in the non-elderly donor group ( P<0.05 for all comparisons). The incidence of hepatic artery complications was 10.71% (3/28) in the elderly donor group and 4.69% (23/490) in the non-elderly donor group, with no statistically significant difference between the two groups ( P>0.05). Statistical analysis employing independent t-tests and χ2 tests demonstrated significant differences between the arterial complication group and non-arterial complication group in donor quality ratio ( P<0.05) and incidence of hepatic arterial hypoperfusion ( P<0.05). Multivariate binary logistic regression analysis, after adjusting for confounding factors (e.g., recipient gender, age, body mass index [BMI], primary disease, and donor-recipient blood type compatibility), identified recipient-to-donor mass ratio ( OR=1.352, P<0.05) and insufficient hepatic arterial blood flow ( OR=1.497, P<0.05) as independent risk factors for arterial complications following liver transplantation. Conclusion:Elderly liver donors can have a certain impact on early postoperative liver function recovery in liver transplant recipients, but have no significant impact on the occurrence of arterial complications after liver transplantation. The mass ratio of recipients to donors and insufficient hepatic arterial blood flow are independent risk factors for arterial complications after liver transplantation.

Patients with alcoholic cirrhosis often experience varying degrees of malnutrition， and the patients with malnutrition are more susceptible to complications such as infections and ascites， which may lead to a poor prognosis. Therefore， it is particularly important to conduct nutritional risk screening for patients in clinical practice， and appropriate nutritional assessment tools should be used to evaluate the nutritional status of patients and develop individualized nutritional supplementation regimens， thereby promoting disease recovery and improving prognosis and quality of life. This article elaborates on the specific methods for nutritional screening， assessment， and management in patients with alcoholic cirrhosis and points out that systematic nutritional screening and assessment can help to identify the patients with malnutrition in the early stage and provide timely intervention. Individualized nutritional supplementation regimens should be adjusted based on the conditions of patients， so as to meet their nutritional needs， promote the recovery of liver function， improve overall health status， and enhance long-term quality of life.

Ulcerative colitis(UC)is a chronic autoimmune disease characterized primarily by impaired intestinal mucosal barrier function.Beneficial bacteria in the intestinal flora are crucial for maintaining intestinal function.Therefore,eliminating harmful bacteria,promoting the regeneration of beneficial bacteria,and reconstructing the intestinal mucosal barrier have become key strategies in the treatment of UC.The traditional Chinese medicine(TCM)"Houchang Theory"elucidates the mech-anism of ulcer formation from the perspective of the"Zhimo"(lipid membrane)structure and a-chieves the purpose of treating UC by thickening the"Zhimo"through syndrome differentiation and treatment.This theory is consistent with the modern medical concept of reconstructing the intestinal mucosal barrier.Fecal microbiota transplantation(FMT),as a transformed product of TCM"Jinzhi"(liquid feces),has been proven to have significant efficacy in the treatment of UC.Based on the TCM"Houchang Theory"and from the perspective of the intestinal mucosal barrier,this article explored the mechanism of"Jinzhi"FMT in the treatment of UC and provides new strategies for clinical treatment.

Objective To investigate the curative effect of early hemoperfusion(HP)in treating patients with sepsis.Methods Early stage sepsis patients admitted to the First People's Hospital of Nanyang City Affiliated to Henan University from January 2020 to December 2022 were selected as the research subjects.These patients were randomly divided into experimental group(62 patients)and control group(31 patients).Early bundle therapy combined with continuous renal replacement therapy(CRRT)were used in both groups as the standard treatment,but only the standard treatment was used in control group.Based on the treatment of control group,the patients in experimental group were treated with HP,the"2-2-1"plan(on the first and second days,connecting resin HP device HA380 in series every 12 hours,and connecting one perfusion device in series on the third day)was applied.The white blood cell count(WBC),C-reactive protein(CRP),procalcitonin(PCT),tumor necrosis factor-α(TNF-α),interleukins(IL-6,IL-10),the hemodynamic indicators(systolic blood pressure,diastolic blood pressure),lactic acid(Lac),sequential organ failure assessment(SOFA),acute physiology and chronic health evaluationⅡ(APACHEⅡ),and the difference in intensive care unit(ICU)hospitalization time of the patients before admission and after 3 day treatment were compared between the two groups.The Kaplan-Meier method was used to draw survival curves and the difference in 28-day survival rates was compared between the two groups.Results After 3 days of treatment,the inflammatory indexes TNF-α,IL-6,IL-10,PCT,CRP,WBC and SOFA score,APACHEⅡscore,Lac in the experimental group all decreased significantly(all P<0.05).In the control group,only the PCT and CRP indexes significantly decreased compared with those before treatment(both P<0.05).Compared with the control group,the difference before and after the change of PCT,CRP,IL-6,IL-10 and SOFA score,APACHEⅡscore,Lac in the experimental group were significant[PCT(μg/L):12.31(6.95,42.69)vs.3.84(1.06,14.47),CRP(mg/L):78.69±64.60 vs.31.49±81.14,IL-6(ng/L):1 357.20(243.96,7 205.50)vs.110.00(-1 749.00,1 377.00),IL-10(ng/L):36.87(5.43,1 218.80)vs.2.67(-11.00,22.79),SOFA score:5(3,7)vs.1(-3,6),APACHEⅡscore:8(5,11)vs.5(-2,7),Lac(mmol/L):3.93±2.89 vs.2.42±2.89,all P<0.05].The clearance rate of inflammatory cytokines IL-6 and IL-10 in the experimental group was higher than that in the control group(IL-6:F=17.93,P<0.001,IL-10:F=6.62,P=0.012).The Kaplan-Meier curve showed the 28-day survival rate of the experimental group was higher than that of the control group(79.03%vs.58.06%),the differences were statistically significant(Log-Rank test:χ2=4.706,P=0.030).Multivariate Cox regression analysis showed that no HP treatment,Lac level before treatment and high APACHEⅡ score were risk factors for death Conclusion HP in the early interventional treatment of sepsis can reduce the levels of inflammatory cytokines and control the inflammatory storm.The HP"2-2-1"treatment frequency can effectively improve the prognosis of septic patients and increase their survival rate.

Objective:To observe the effect of bone forming protein 4 (BMP4) on the proliferation and migration of human retinal pigment epithelium (RPE) cells under oxidative stress, and to preliminarily explore its effect on epithelial-mesenchymal transition (EMT) of RPE cells.Methods:Human RPE cells cultured in vitro were divided into normal group, pure 4-hydroxynonenal (HNE) group (4-HNE group), 4-HNE+NC group and 4-HNE+ small interfering BMP (siBMP4) group. The effect of 4-HNE on the proliferation of RPE cells was detected by thiazole blue colorimetry. The effects of 4-HNE and BMP4 on cell migration were determined by cell scratch test. The expression of BMP4 was detected by immunofluorescence staining, Western blot and real-time quantitative polymerase chain reaction. The transfection efficiency of siBMP4 was observed by fluorescence microscopy. Mitochondrial reactive oxygen species (MitoSOX) were detected by flow cytometry. The expression of EMT markers E-cadherin and Fibronection were detected by immunofluorescence assay. t-test was used for comparison between the two groups, and one-way analysis of variance was used for comparison between the three groups. Results:Compared with normal group, cell proliferation and migration ability of 4-HNE group were significantly enhanced, with statistical significance ( t=21.619, 24.469; P<0.05). The expression of BMP4 in cells was significantly increased, and the difference was statistically significant ( t=19.441, P<0.05). The relative expression levels of BMP4 mRNA and protein were also significantly increased, with statistical significance ( t=26.163, 37.163; P<0.05). After transfection with siBMP4 for 24 h, the transfection efficiency of BMP4 in RPE cells was>90%. Compared with 4-HNE group and 4-HNE+NC group, the relative expression levels of BMP4 protein ( F=27.241), mRNA ( F=36.943), cell mobility ( F=46.723) and MitoSOX expression levels ( F=39.721) in normal group and 4-HNE+siBMP4 group were significantly decreased. The differences were statistically significant ( P<0.05). The epithelial marker E-cadherin increased significantly, while the mesenchymal marker Fibronection decreased significantly, with statistical significance ( F= 51.722, 45.153; P<0.05). Conclusions:BMP4 inhibits RPE proliferation and migration under oxidative stress. BMP4 is involved in inducing EMT in RPE cells.

Objective:To explore the effect of cathepsin L (CTSL) inhibitor on apoptosis of retinal pigment epithelial (RPE) cells and mitochondrial oxidative stress.Methods:RPE cells were cultured in vitro and divided into control group, hydrogen peroxide (H 2O 2) group, and H 2O 2+CTSL inhibitor group. The cells of H 2O 2 group and H 2O 2+CTSL inhibitor group were incubated in the medium containing 400 μmol/L H 2O 2 for 24 hours and 10 μmol/L CTSL inhibitor was added in H 2O 2+CTSL inhibitor group at the same time. The cells of normal group were routinely cultured cells. The follow-up experiment was carried out 24 hours after modeling. The rate of apoptosis was detected by flow cytometry. The expression of CTSL was detected by immunofluorescence staining, Western blot and real time-polymerase chain reaction. The level of mitochondrial super oxide was detected by MitoSOX fluorescent probe, and the mitochondrial structure was observed after MitoTracker staining, the average area, form factors, and branch of mitochondria were quantitatively analyzed. The two groups were compared using two-tailed Student t test, while numerous groups were compared using one-way ANOVA. Results:Compared with control group, the rate of apoptosis in H 2O 2 group was significantly higher ( t=3.307, P=0.029 7), the expression level of CTSL was significantly increased ( t=19.950, 6.916, 14.220; P<0.05). Compared with H 2O 2 group, the expression level of CTSL, the rate of apoptosis and the mitochondrial ROS level in H 2O 2+CTSL inhibitor group were significantly lower ( t=11.940, 4.718, 16.680; P<0.05). The mitochondria of H 2O 2+CTSL inhibitor group were elongated, oval-shaped or rod-shaped, while the mitochondria of H 2O 2 group lost their continuous contour shape and complete structure. The differences of the average area, form factors, and brach of mitochondria among 4 groups were statistically significant ( F=251.700, 34.010, 60.500; P<0.000 1). Conclusions:H 2O 2 can significantly induce apoptosis in RPE cells and increase CTSL expression. CTSL inhibitor can inhibit the H 2O 2-induced apoptosis of RPE cells, lower the mitochondrial super oxide level, and successfully repair the mitochondrial structure.
