RESUMO
Objective: To identify the predisposing factors, clinical characteristics, and risk factors of disease progression to establish a novel predictive survival model and evaluate its application value for hepatitis B virus-related acute-on-chronic liver failure. Methods: 153 cases of HBV-ACLF were selected according to the guidelines for the diagnosis and treatment of liver failure (2018 edition) of the Chinese Medical Association Hepatology Branch. Predisposing factors, the basic liver disease stage, therapeutic drugs, clinical characteristics, and factors affecting survival status were analyzed. Cox proportional hazards regression analysis was used to screen prognostic factors and establish a novel predictive survival model. The receiver operating characteristic curve (ROC) was used to evaluate predictive value with the Model for End-Stage Liver Disease (MELD) and the Chronic Liver Failure Consortium Acute-on-Chronic Liver Failure score (CLIF-C ACLF). Results: 80.39% (123/153) based on hepatitis B cirrhosis had developed ACLF. HBV-ACLF's main inducing factors were the discontinuation of nucleos(t)ide analogues (NAs) and the application of hepatotoxic drugs, including Chinese patent medicine/Chinese herbal medicine, non-steroidal anti-inflammatory drugs, anti-tuberculosis drugs, central nervous system drugs, anti-tumor drugs, etc. 34.64% of cases had an unknown inducement. The most common clinical symptoms at onset were progressive jaundice, poor appetite, and fatigue. The short-term mortality rate was significantly higher in patients complicated with hepatic encephalopathy, upper gastrointestinal hemorrhage, hepatorenal syndrome, and infection (P < 0.05). Lactate dehydrogenase, albumin, the international normalized ratio, the neutrophil-to-lymphocyte ratio, hepatic encephalopathy, and upper gastrointestinal bleeding were the independent predictors for the survival status of patients. The LAINeu model was established. The area under the curve for evaluating the survival of HBV-ACLF was 0.886, which was significantly higher than the MELD and CLIF-C ACLF scores (P < 0.05), and the prognosis was worse when the LAINeu score ≥ -3.75. Conclusion: Discontinuation of NAs and the application of hepatotoxic drugs are common predisposing factors for HBV-ACLF. Hepatic decompensation-related complications and infection accelerate the disease's progression. The LAINeu model can predict patient survival conditions more accurately.

Objective: To investigate the relationship between plasma Golgi protein 73 (GP73) levels and the occurrence and development of non-alcoholic fatty liver disease (NAFLD), and to establish a diagnostic model based on this combination with lipid metabolism indicators to clarify its diagnostic efficacy and clinical application value for NAFLD. Methods: 225 cases with NAFLD [diagnosed by ultrasound, transient elastography (FibroScan502) and liver biopsy (some patients)] and 108 healthy controls were selected from the Department of Hepatology and Physical Examination Center of Integrated Traditional Chinese and Western Medicine, The Third Hospital of Hebei Medical University. Clinical data, routine peripheral blood and serum biochemical test results were collected. The plasma GP73 level was detected by enzyme-linked immunosorbent assay. SPSS 21.0 statistical software was used for statistical analysis. Binary logistic regression model was used to calculate the NAFLD diagnostic model. Receiver operating characteristic curve was used to evaluate the NAFLD constructed model diagnostic efficacy. Results: NAFLD incidence was significantly reduced in younger age group, mostly in young and middle-aged male. However, the NAFLD incidence was increased with increasing age in female. The analysis of age ratio composition showed that the average age for NAFLD onset was 20 ~ 50 years old, and the incidence rate was as high as 47% in among 30 ~ 39 years old, but the incidence rate was significantly decreased in over 60 years old (4.00%). GP73 was an independent risk factor for the occurrence and development of NAFLD. The diagnostic models of GBT, GB and GT were established by GP73 (G) combined with body mass index (BMI, B) and serum triglyceride (TG, T), and the results showed that the areas under the curves of GBT, GB and GT models were 0.969, 0.937 and 0.909, respectively. The sensitivity and the specificity were 84.90%, 77.80% and 84.00%, and 95.40%, 95.40% and 82.40%, respectively, P < 0.05. The GBT model had efficacy of best diagnostic performance. Conclusion: NAFLD is more common in young and middle-aged male, but with advanced age, the incidence of female patients gradually increases. Plasma GP73 levels are related to the occurrence and development of NAFLD. The GBT model can be used as a new model for non-invasive diagnosis and one of the indicators for clinical evaluation of diagnostic efficacy of NAFLD.

Objective: To determine the diagnostic value of plasma heme oxygenase 1 (HO-1) in the occurrence, development, and pathological stages of chronic hepatitis B-related liver fibrosis. Methods: 211 outpatients and inpatients with chronic hepatitis B (CHB) and 57 healthy controls who visited the Third Hospital of Hebei Medical University were selected. Simultaneously, clinical data, peripheral blood routine and serum biochemical test results of the research subjects were collected. Plasma HO-1 levels were detected by enzyme-linked immunosorbent assay (ELISA). Liver fibrosis (S1 ~ 4) was staged according to liver biopsy and liver stiffness measurement (LSM). Statistical analysis: binary logistic regression was used to analyze the independent risk factors of hepatitis B-related liver fibrosis to establish a diagnostic model, and the receiver operating characteristic curve (ROC) was used to compare and analyze the staging efficiency of HO-1, new model, FIB-4 and APRI for the diagnosis of liver fibrosis. Results: Plasma HO-1 levels were significantly higher in CHB patients than healthy controls [10.11 (7.08 ~ 13.12) ng/ml and 6.71 (5.56 ~ 8.45) ng/ml, (P < 0.001)]. There were 37, 38, 38, and 98 cases with liver fibrosis stages S1, S2, S3, and S4, respectively and plasma HO-1 level was (6.91 ± 2.80) ng/ml, (8.24 ± 2.44) ng/ml, (9.96 ± 3.46) ng/ml, (12.65 ± 3.70) ng/ml, P < 0.001. HO-1, albumin, and platelets (PLT) were independent risk factors for liver fibrosis. A HAP model was established. HAP, FIB-4 and APRI sensitivity and specificity for the diagnosis of liver fibrosis staging were as follows: ≥S2 were 84.62%, 72.35 %, 81.18% and 83.78%, 81.08%, 67.57%; ≥S3 were 80.15%, 82.09%, 85.82% and 88.64%, 76.19%, 60.32%; S4 were 90.82%, 82.29%, 86.46% and 74.37%, 65.77%, 48.65%, respectively. Conclusion: Plasma HO-1 level can reflect the severity of liver fibrosis. HAP diagnostic model can more accurately mirror the process of liver fibrosis than FIB-4 and APRI, and point clinical diagnosis and prognosis assessment.

Objective: To explore the optimal ratio of dihydrotestosterone and hydroxyflutamide (hereinafter referred to as DH), construct a dual release system of androgen and its antagonist, and analyze the application effect of this system in the repair of full-thickness burn wounds in mice. Methods: This study was an experimental study. The HaCaT cells were divided into blank group (without drug culture), low baseline group, medium baseline group, and high baseline group according to the random number table (the same grouping method below), and the last three groups of cells were cultured by adding three different ratios of DH. Under a medium ratio, the mass of dihydrotestosterone in the three baseline groups from low to high was 1.4, 2.8, and 4.0 µg, respectively, and the mass of hydroxyflutamide was 1.2, 1.6, and 2.0 µg, respectively. On this basis, under a small ratio, the mass of dihydrotestosterone was reduced by half and the mass of hydroxyflutamide was increased by half; under a large ratio, the mass of dihydrotestosterone was increased by half and the mass of hydroxyflutamide was reduced by half. After culture of 2 days, the cell proliferation level was detected by cell counting kit 8 (n=4). Sixteen 6-8-week-old male BALB/c mice were used to establish a full-thickness burn wound on the back and divided into blank group, small ratio group, medium ratio group, and large ratio group, with 4 mice in each group. On post injury day (PID) 7, normal saline containing different ratios of DH was locally dropped to the wounds of mice in the last three groups of mice (the total mass of DH in the three ratio groups from small to large was 127.5, 165.0, and 202.5 µg, respectively, and the mass ratios of dihydrotestosterone to hydroxyflutamide (hereinafter referred to as drug mass ratio) were 8â¶9, 8â¶3, and 8â¶1, respectively), afterwards, the administration was repeated every 48 hours until PID 27; normal saline was dropped to the wound of mice in blank group at the aforementioned time points. The wound healing status on PID 0 (immediately), 7, 14, 21, and 28 was observed, and the wound healing rates on PID 7, 14, 21, and 28 were calculated (n=4). On PID 28, the wound tissue was taken, which was stained with hematoxylin and eosin for observing re-epithelialization and with Masson for observing collagen fibers, and the proportion of collagen fibers was analyzed (n=3). Twenty 6-8-week-old male BALB/c mice were used to establish a full-thickness burn wound on the back and divided into ordinary scaffold group, small proportion scaffold group, medium proportion scaffold group, and large proportion scaffold group (with 5 mice in each group). On PID 7, the wound was continuously dressed with a polycaprolactone scaffold without drug and a polycaprolactone scaffold containing DH with a drug mass ratio of 1â¶3, 1â¶1, or 3â¶1 (i.e. the dual release system of androgen and its antagonist, with total mass of DH being about 1.7 mg) prepared by using electrospinning technology until the end of the experiment. Histopathological analyses of tissue (n=3) at the same time points as those in the previous animal experiment were performed. On PID 7 and 14, the wound exudates were collected and the relative abundance of bacterial communities was analyzed using 16S ribosomal RNA high-throughput sequencing (n=3). Results: After culture of 2 days, under a small ratio, the proliferation levels of HaCaT cells in low baseline group and high baseline group were significantly higher than the level in blank group (P<0.05). As the time after injury prolonged, the wounds of all four groups of mice continued to shrink. On PID 14, the wound healing rate of mice in large ratio group was 72.5% (61.7%, 75.1%), which was close to 53.3% (49.5%, 64.4%) in blank group (P>0.05); the wound healing rates of mice in small and medium ratio groups were 74.2% (71.0%, 84.2%) and 70.4% (65.1%, 74.4%), respectively, which were significantly higher than the rate in blank group (with both Z values being -2.31, P<0.05). On PID 21, the wound healing rate of mice in small ratio group was significantly higher than that in blank group (Z=-2.31, P<0.05). On PID 28, the wounds of mice in the three ratio groups were completely re-epithelialized and the epidermis was thicker than that in blank group; compared with that in blank group, the collagen fiber content in the wound tissue of mice in the three ratio groups was higher and arranged more orderly, and the proportions of collagen fibers in the wound tissue of mice in small and large ratio groups were significantly increased (P<0.05). On PID 28, the wounds of mice in ordinary scaffold group were partially epithelialized, while the wounds of mice in the three proportion scaffold groups were almost completely epithelialized. Among them, the wounds of mice in small proportion scaffold group had the thickest epidermis. The proportion of collagen fibers in the wound tissue of mice in small proportion scaffold group was significantly increased compared with that in ordinary scaffold group (P<0.05). On PID 7, the bacterial communities with high relative abundance in the wound exudation of mice in the four groups included bacteria of Corynebacterium, Staphylococcus, and Rhodococcus. On PID 14, the bacterial communities with high relative abundance in the wound exudation of mice in the four groups included bacteria of Stenotrophomonas, Rhodococcus, and Staphylococcus, and the number of bacterial species in the wound exudation of mice in the three proportion scaffold groups was more than that in ordinary scaffold group. Conclusions: When the drug mass ratio is relatively small, DH has the effect of promoting the proliferation of HaCaT cells. The ratio of 8â¶9 is the optimal mass ratio of dihydrotestosterone to hydroxyflutamide, and DH with this mass ratio can promote re-epithelialization and collagen deposition of full-thickness burn wounds in mice, and promote wound healing. The constructed dual release system of androgen and its antagonist with DH in a 1â¶3 drug mass ratio contributes to the re-epithelialization and collagen deposition of the full-thickness burn wounds in mice, and can improve the diversity of wound microbiota.
