Objective To investigate the clinical efficacy of Jiedu Huayu Granules(mainly composed of the Chinese herbal medicines of Artemisiae Scopariae Herba,Rhei Radix et Rhizoma,Hedyotis Diffusae Herba,Paeoniae Radix Rubra,Curcumae Radix and Acori Tatarinowii Rhizoma)in the treatment of liver failure(LF)and to observe their effects on endoplasmic reticulum stress and inflammatory response.Methods From May 2022 to May 2024,a total of 102 patients with LF of toxin-heat-stasis stagnation syndrome were collected from Hepatology Department of Yulin Traditional Chinese Medicine Hospital,and were divided into the control group and the study group by using a table of random numbers,with 51 cases in each group.The two groups were given comprehensive western medicine treatment for inhibiting inflammatory response and protecting liver,regulating intestinal microecology,counteracting viral infection,decreasing transaminase level and treating jaundice.Additionally,the study group was treated with Jiedu Huayu Granules.The course of treatment for the two groups covered eight weeks.Before and after treatment,the two groups were observed in the changes of traditional Chinese medicine(TCM)syndrome scores,biochemical indicators,inflammatory factors and endoplasmic reticulum stress indicators.After treatment,the clinical efficacy and the incidence of adverse reactions of the two groups of patients were compared.Results(1)After eight weeks of treatment,the total effective rate of the study group was 86.27%(44/51)and that of the control group was 68.63%(35/51),and the intergroup comparison(tested by chi-square test)showed that the efficacy of the study group was significantly superior to that of the control group(P<0.05).(2)After treatment,the TCM syndrome scores in both groups were significantly decreased compared with those before treatment(P<0.01),and the decrease in the study group was significantly superior to that in the control group(P<0.05).(3)After treatment,the serum levels of biochemical indicators of total bilirubin(TBIL),total bile acid(TBA),alanine transaminase(ALT),and aspartate transaminase(AST)in the two groups were significantly decreased compared with those before treatment(P<0.05),and the decrease in the study group was significantly superior to that in the control group(P<0.05 or P<0.01).(4)After treatment,the serum levels of inflammatory factors of interleukin 6(IL-6),tumor necrosis factor α(TNF-α),transforming growth factor β(TGF-β),and C-reactive protein(CRP)in the two groups were significantly decreased compared with those before treatment(P<0.05),and the decrease in the study group was significantly superior to that in the control group(P<0.01).(5)After treatment,the levels of endoplasmic reticulum response indicators such as glucose-regulated protein 78(GRP78),CCAAT enhancer-binding protein homologous protein(CHOP),and cysteine aspartic acid specific protease 12(caspase-12)in the two groups were significantly decreased compared with those before treatment(P<0.05),and the decrease in the study group were significantly superior to those in the control group(P<0.01).(6)The incidence of adverse reactions in the study group was 15.69%(8/51)and that in the control group was 17.65%(9/51),and the comparison between the two groups showed that the difference was not statistically significant(P>0.05).Conclusion The combined use of Jiedu Huayu Granules with comprehensive western medicine treatment exerts certain efficacy in treating patients with LF of toxin-heat-stasis stagnation syndrome.The combined therapy is effective on relieving clinical symptoms and improving liver function,and is helpful for relieving endoplasmic reticulum stress and inflammatory response.

Objective To evaluate the combination score of albumin-bilirubin index(ALBI)and alkaline phosphatase(ALP)in predicting the prognosis of patients with cirrhosis complicated by portal hypertension after receiving transjugular intrahepatic portosystemic shunt(TIPS).Methods A total of 61 patients with cirrhosis complicated by portal hypertension,who received TIPS treatment at the Lishui Municipal Central Hospital of China from January 2016 to June 2024,were retrospectively collected.According to the Youden index of ALBI and ALP,the optimal cut-off values were calculated,and the patients were divided into low ALBI-low ALP group(0-point group),high ALBI-high ALP group(2-point group),and high ALBI-low ALP or low ALBI-high ALP group(one-point group).The efficacy of ALBI-ALP score in predicting the prognosis of patients was evaluated,and the survival rate and median survival time were compared between each other among the three groups.The independent risk factors affecting the survival time of patients were analyzed.Results The maximum Youden indexes of ALBI and ALP were 0.31 and 0.34 respectively,and the optimal cut-off values were-1.56 and 108.50 respectively.There were statistically significant differences in MELD score,Child-Pugh classification,and alanine aminotransferase level between each other among the three groups(all P＜0.05).The area under the ROC curve(AUC)of ALBI-ALP score was 0.77(95％ CI:0.66-0.89,P=0.000 2),which was better than 0.52 of the MELD score(95％ CI:0.37-0.67,P=0.77)as well as better than 0.57 of the Child-Pugh classification(95％ CI:0.43-0.72,P=0.34).The total mortality of patients was 49.18％.The mortality in the 0-point group was 11.11％(2/18),which was significantly lower than 59.46％(22/37)in the one-point group as well as than 100％(6/6)in the 2-point group,and the differences were statistically significant(x2=18.20,P＜0.001).In the 0-point group,as a large number of patients were still alive at the end of the study,the median survival time was unable to be calculated.The median survival time in the one-point group was 38.00 months(95％ CI:23.01-52.99 months),which in the 2-point group was only 1.00 month(95％ CI=0.00-2.60 months),the difference was statistically significant(x2=33.08,P＜0.000 1).In the 0-point group,one-point group and 2-point group,the one-year survival rates were 100％,66％ and 17％respectively,the 2-year survival rates were 100％,64％ and 17％ respectively,and the 3-year survival rates were 90％,53％ and 0％ respectively.Cox multivariate regression analysis showed that the combination score of ALBI and ALP(HR=7.11,95％ CI:2.95-17.15)was an independent risk factor for the survival time of patients with cirrhosis complicated by portal hypertension after receiving TIPS.Conclusion The combination score of ALBI and ALP can effectively predict the prognosis of patients with cirrhosis complicated by portal hypertension after receiving TIPS,and this score is an independent risk factor affecting the survival time of patients.

Objective To discuss the effect of PI3K-AKT signaling pathway regulated by microRNA-155(miRNA-155)targeted protein tyrosine phosphatase non-receptor type 21(PTPN21)on the proliferation,migration and invasion of hepatocellular carcinoma(HCC)cells.Methods Lentivirus transfection was used to silence the expression of miRNA-155 in human Huh7 HCC cells,and real-time fluorescent quantitative polymerase chain reaction(RT-qPCR)was used to detect the silencing effect of miR-155.After obtaining stable cell lines,the cell lines were randomly divided into Blank group(normal Huh7 cells),shNC group(Huh7 cells+empty miR-155 vector),sh-miR-155(Huh7 cells+miR-155 silencing),sh-miR-155+Recilisib group(Huh7 cells+miR-155 silencing+PI3K-AKT agonist),shNC+Recilisib group(Huh7 cells+empty miR-155 vector+PI3K-AKT agonist).Dual luciferase assay was used to determine whether PTPN21 was the downstream of miR-155.The cell proliferation ability of cells in each group was detected by MTT assay.The apoptosis level of each group was tested by flow cytometry.The invasion and migration ability of cells was assessed by Transwell assay.Western blot analysis was used to observe the differences in protein expression of PTPN21,PI3K,P-PI3K,AKT,P-AKT,and apoptosis-related proteins including BAX,BCL-2 and caspase-3 in all groups.Results The expression level of miR-155 in sh-miR-155 group was lower than that in Blank group and shNC group(P＜0.000 1),and the difference in miR-155 expression level between Blank group and shNC group was not statistically significant(P＞0.05).MTT results showed that A values of Huh7 cells at 2,3,4 and 5 day in sh-miR-155 group were lower than those in Blank group and shNC group(P＜0.000 1),while these differences between Blank group and shNC group were not statistically significant(P＞0.05).In sh-miR-155 group the A values at 2,3,4 and 5 day were lower than those in sh-miR-155+Recilisib group and shNC+Recilisib group(P=0.0052 and P＜0.0001,respectively),while the A values at 2,3,4 and 5 day in sh-miR-155+Recilisib were lower than those in shNC+Recilisib group(P＜0.000 1).There was no significant differences in cell migration and number of invasion cells between the Blank group and shNC group(P＞0.05).After activation of PI3K-AKT signaling pathway,the migration and invasion capacity of HCC cells in the shNC+Recilisib group were significantly enhanced when compared with the Blank group(P＜0.000 1).In contrast,the number of migrated and invaded Huh7 cells after miR-155 silencing was significantly lower than that in the Blank group and shNC group(P＜0.000 1)and this phenomenon became reversed by PI3K agonist.Compared with the sh-miR-155 group,in the sh-miR-155+Recilisib group the migration and invasion ability of HCC cells was enhanced(P=0.000 2).Lentiviral transfection of Huh7 human HCC cells to silence miR-155 and downregulate miR-155 inhibiting PTPN21 regulation of the PI3K-AKT signaling pathway,thus inhibiting the invasion,migration and proliferation ability of HCC cells and promoting the apoptosis of HCC cells.Conclusion miR-155 inhibits the migration,invasion and proliferation of HCC cells through targeting PTPN21 regulation of PI3K-AKT signaling pathway.The miR-155 may be a potential therapeutic target for HCC in the future.(J Intervent Radiol,2024,32:44-51)

Objective:To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients.Methods:Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control.Results:Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95% CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95% CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern ( OR=0.71, 95% CI: 0.52-0.98) and fruit-aquatic products-potato patterns ( OR=0.71, 95% CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns ( OR=0.60, 95% CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern ( OR=1.41, 95% CI: 1.03-1.94; OR=1.68, 95% CI: 1.13-2.51) and egg-milk-bean pattern ( OR=1.75, 95% CI: 1.25-2.46; OR=1.56, 95% CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q2 group), egg-milk-bean pattern ( Q3 group)" was higher ( OR=6.79, 95% CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q3 group), egg-milk-bean pattern ( Q2 group), oil-salt pattern ( Q2 group)" had higher control rate of 2 h PBG ( OR=12.78, 95% CI: 1.26-130.05, P=0.031). Conclusions:A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.

Objective:To describe the prevalence of food allergy among children aged 0-5 years in China and to explore related influencing factors.Methods:Multistage stratified random sampling method was used to collect data from 275 surveillance sites of the China National Nutrition and Health Survey of Chinese children and lactating mothers programs in 31 provinces (autonomous regions and municipalities) of China in 2016-2017. A total of 70 107 participants aged 0-5 years were included in this study. The study collected information of participants' demographic characteristics and food allergies by face-to-face questionnaire. The prevalence of food allergy was analyzed, using the complex data weighting method. The logistic regression models were used to analyze the influencing factors related to food allergy.Results:The overall prevalence of self-reported food allergy among children aged 0-5 years was 4.81%. Prevalence rates in infants aged 0-5 months, and 6-23 months and preschool children aged 2-5 years were 0.81%, 4.68% and 5.26%, respectively. The results of logistic analysis showed that there was a significantly positive correlation between factors including children from 6 months to 5 years old, urban area, southwest area, first-born, mothers with college education or above, and the prevalence of food allergy in children. Shrimp, poultry eggs, crab shellfish, fruit, milk and fish appeared the common allergic foods in children aged 0-5 years, with prevalence rates of self-reported food allergy as 1.55%, 1.25%, 0.99%, 0.97%, 0.87% and 0.86%, respectively. The proportion of single food allergy in children with allergies was 69.85%.Conclusions:Among children aged 0-5 years, the prevalence of self-reported food allergy increases with age, in China. Foods that is prone to allergies include fish, shrimp, crab, shellfish, poultry eggs, milk and fruits, etc. Most allergies were only caused by single food in children, under observation.

Purpose To explore the clinicopathological features of cholangitis lenta.Methods The clinical data of 12 patients with cholangitis Lenta were collected,HE staining,his-tochemical staining and immunohistochemistry were used to de-tect the clinicopathological changes in 12 cases of cholangitis lenta,and the relevant literature was reviewed.Results All the 12 patients with cholangitis Lenta had acute history and ab-normal liver function,9 cases(75.0％)had abnormal white blood cell count,11 cases(91.7％)had abdominal infection,8 cases(66.7％)had systemic inflammatory response syndrome(SIRS)and 8 cases(66.7％)were diagnosed as sepsis.The common pathological manifestations included spotty necrosis(100％),piecemeal necrosis(100％),confluent necrosis(75.0％),bridging necrosis(66.7％),hepatocyte and capil-lary cholestasis(75.0％),and mild edema in portal area(33.3％).12 cases showed proliferation of bile ductules around the portal area,inspissated bile in dilated bile ductules and no cholestasis in interlobular bile ducts.12 cases had the basis of primary liver disease.2 patients(16.7％)died after being transferred to another hospital for treatment,and 10 patients(83.3％)survived,which lasted for 7 to 55 months.Conclu-sion Cholangitis Lenta shows unique clinical manifestations and morphological features,it is often accompanied by underly-ing diseases.The pathological manifestation of cholangitis Lenta in liver biopsy suggests that patients may have sepsis and/or ab-dominal infection,and therefore its diagnosis should be com-bined with clinical features,laboratory examination and imaging manifestations.

Objective:To investigate the application value of peri-gastric devasculariza-tion without dissociation of esophagus for portal hypertension.Methods:The retrospective and descriptive study was conducted. The clinical data of 94 patients with portal hypertension who were admitted to three medical centers, including 75 cases in the People′s Hospital of Ningxia Hui Autonomous Region, 12 cases in the People′s Hospital of Wuhai and 7 cases in the People′s Hospital of Wuzhong, from July 2018 to December 2022 were collected. There were 68 males and 26 females, aged 46(range, 21-70)years. All 94 patients underwent peri-gastric devascularization without dissociation of esophagus. Observation indicators: (1) intraoperative condition; (2) postoperative complications; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measure-ment data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Intraoperative condition. All 94 patients underwent surgery success-fully without operation death, including 82 cases receiving open surgery and 12 cases receiving laparoscopic surgery. The operation time and volume of intraoperative blood loss were (183±85)minutes and 289(range, 158-560)mL, respectively, for the 94 patients. (2) Postoperative complications. Of 94 patients, early portal vein thrombosis occurred in 24 cases, intra-abdominal infection occurred in 2 cases, hepatic encephalopathy occurred in 1 case, pulmonary embolism occurred in 1 case, intra-abdominal hemorrhage requiring operation to stop bleeding occurred in 1 case and pleural effusion requiring drainage occurred in 1 case. All patients with postoperative complications were cured after treatment. None of the 94 patient had postoperative esophageal complications such as odynophagia or dysphagia. (3) Follow-up. All 94 patients were followed up for 38(range, 6-60)months. Of the 45 patients with paraesophageal vein, there were 36 cases of thinner and 9 cases of occlusion of the distal subphrenic paraesophageal vein after surgery, respectively. Cases with esophageal varices disappearance, cases with mild and moderate residual of esophageal varices, cases with severe residual of esophageal varices, cases with recurrence of esophageal varices, cases with esophageal varices bleeding were 7, 70, 9, 4, 4 in the 94 patients after surgery. Cases with esophageal varices disappearance was 7 in the 45 patients with paraesophageal vein, versus 0 in the 49 patients without paraesophageal vein, showing a significant difference between them ( P<0.05). Of 94 patients, 17 cases developed postoperative late portal vein thrombosis and cavernous transformation, 7 cases developed liver cancer, 1 case had hepatic encephalopathy, and 6 cases died. Conclusion:Peri-gastric devascularization without dissociation of esophagus is safe and feasible for the treatment of portal hypertension.

Protein corona (PC) has been identified to impede the transportation of intravenously injected nanoparticles (NPs) from blood circulation to their targeted sites. However, how intestinal PC (IPC) affects the delivery of orally administered NPs are still needed to be elucidated. Here, we found that IPC exerted "positive effect" or "negative effect" depending on different pathological conditions in the gastrointestinal tract. We prepared polystyrene nanoparticles (PS) adsorbed with different IPC derived from the intestinal tract of healthy, diabetic, and colitis rats (H-IPC@PS, D-IPC@PS, C-IPC@PS). Proteomics analysis revealed that, compared with healthy IPC, the two disease-specific IPC consisted of a higher proportion of proteins that were closely correlated with transepithelial transport across the intestine. Consequently, both D-IPC@PS and C-IPC@PS mainly exploited the recycling endosome and ER-Golgi mediated secretory routes for intracellular trafficking, which increased the transcytosis from the epithelium. Together, disease-specific IPC endowed NPs with higher intestinal absorption. D-IPC@PS posed "positive effect" on intestinal absorption into blood circulation for diabetic therapy. Conversely, C-IPC@PS had "negative effect" on colitis treatment because of unfavorable absorption in the intestine before arriving colon. These results imply that different or even opposite strategies to modulate the disease-specific IPC need to be adopted for oral nanomedicine in the treatment of variable diseases.

PEP06 is a novel endostatin-Arg-Gly-Asp-Arg-Gly-Asp(RGDRGD)30-amino-acid polypeptide featuring a terminally fused RGDRGD hexapeptide at the N terminus.The active endostatin fragment of PEPO6 directly targets tumor cells and exerts an antitumoral effect.However,little is known about the kinetics and degradation products of PEP06 in vitro or in vivo.In this study,we investigated the in vitro metabolic stability of PEP06 after it was incubated with living cells obtained from animals of different species;we further identified the degradation characteristics of its cleavage products.PEP06 underwent rapid enzymatic degradation in multiple types of living cells,and the liver,kidney,and blood play important roles in the metabolism and clearance of the peptides resulting from the molecular degradation of PEP06.We identified metabolites of PEP06 using full-scan mass spectrometry(MS)and tandem MS(MS2),wherein 43 metabolites were characterized and identified as the degradation metabolites from the parent peptide,formed by successive losses of amino acids.The metabolites were C and N terminal truncated products of PEP06.The structures of 11 metabolites(M6,M7,M16,M17,M21,M25,M33,M34,M39,M40,and M42)were further confirmed by comparing the retention times of similar full MS spectrum and MS2 spectrum information with reference standards for the synthesized metabolites.We have demonstrated the metabolic stability of PEP06 in vitro and identified a series of potentially bioactive downstream metabolites of PEP06,which can support further drug research.
