Objective To investigate the value of serum markers in the early diagnosis of liver cirrhosis with minimal hepatic encephalopathy (MHE). Methods A prospective analysis was performed for 81 patients who were hospitalized and treated in General Hospital of Ningxia Medical University from April 2020 to February 2022, and all these patients were diagnosed with hepatitis B cirrhosis based on clinical manifestation, laboratory examination, and radiological examination or liver biopsy. According to digital connection test A (NCT-A) and digital symbol test (DST), these patients were divided into simple cirrhosis group with 45 patients and MHE group with 36 patients. Related indices were measured, including liver function [alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), and total bilirubin (TBil)], albumin, blood ammonia, cholinesterase, and prothrombin time. The independent samples t -test was used for comparison of normally distributed continuous data between two groups; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups; the chi-square test was used for comparison of categorical data between groups. The logistic regression analysis and the area under the ROC curve (AUC) were used to investigate the predictive factors for MHE. Results Compared with the simple cirrhosis group, the MHE group had a significant increase in NCT-A score ( Z =-7.110, P < 0.001) and a significant reduction in DST score ( t =12.223, P < 0.001). The univariate analysis showed that there were significant changes in AST, albumin, prothrombin time, cholinesterase, and blood ammonia in the patients with MHE ( Z =-2.319, -2.643, -1.982, -6.594, and -5.331, all P < 0.05), while the multivariate analysis showed that only cholinesterase and blood ammonia were significant predictive factors (all P < 0.05) and were correlated with Child-Pugh score (all P < 0.05). Cholinesterase, blood ammonia, and their combination had an AUC of 0.925, 0.845, and 0.941, respectively, in the diagnosis of MHE, with an optimal cut-off value of 2966, 60, and 0.513, respectively. Conclusion Blood ammonia, cholinesterase, and their combined measurement have a potential clinical value in the early diagnosis of liver cirrhosis with MHE.

Objective:To study the remote multi-disciplinary team (MDT) model in diagnosis and treatment of plague, in order to provide scientific basis for clinical treatment of plague.Methods:A retrospective analysis was made on the diagnosis and treatment process of a case of bubonic plague, a sudden imported Class A infectious disease, which was secondary to septicemic plague, involving a remote MDT team consisting of the Infectious Diseases Department, Intensive Care Unit, Respiratory and Critical Care Department, Cardiology Department, Pharmacy Department, and Nosocomial Infection Department of the General Hospital of Ningxia Medical University.Results:The patient was a middle-aged female who was engaged in herding work on the grassland. The first symptom was a sudden pain in the left lower abdomen for three days, accompanied by chest tightness and shortness of breath. After hospitalization, blood culture indicated Yersinia, abdominal CT indicated left lower abdominal lymph node enlargement, and lymph node puncture fluid was positive for Yersinia pestis nucleic acid. Combined with clinical symptoms and signs, the patient was diagnosed as bubonic plague secondary to septicemic plague, and was isolated for treatment. After remote MDT consultation, comprehensive treatment was given, including anti-infection treatment of streptomycin and ciprofloxacin, short-term application of hormones, nutritional support, and local application of chloramphenicol ointment, etc. Secondary acute pancreatitis occurred during the course of the disease, which improved after symptomatic treatment. Finally, after 20 days of treatment, MDT expert group assessed that it met the discharge criteria. No abnormalities were found in follow-up visits outside the hospital. Conclusion:The remote MDT is effective in the treatment of bubonic plague secondary to septicemic plague, which is worth popularizing.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To explore the influencing factors and the impact of artificial liver treatment on the prognosis and survival of patients with acute-on-chronic liver failure (ACLF).Methods:Clinical data from 201 cases with ACLF from January 2016 to December 2019 was retrospectively analyzed. The survival rate was calculated by the Kaplan-Meier method, the log-rank test of univariate analysis, and the multivariate analysis of the stepwise Cox regression forward method.Results:The median survival time of patients was 6 months, and the survival rates at 6, 9, and 12 months were 51.2%, 38.3%, and 29.9%, respectively. In univariate analysis, age, presence or absence of hypertension and upper gastrointestinal bleeding, treatment method, model for end-stage liver disease (MELD) score, and cholinesterase were associated with prognosis ( P < 0.05). Multivariate regression analysis results showed that MELD score was the main factor affecting the 1-year prognosis of ACLF patients ( P = 0.002). Artificial liver treatment was beneficial for the 1-year prognosis of ACLF patients aged < 50 years or with a MELD score of ≥20 ( P < 0.05 ). The relative risk ratio (RR) of mortality was 2.55 times higher in patients with advanced age (≥50 years old) than that of younger patients ( P < 0.001). Regression analysis was performed using age as a stratification factor, and upper gastrointestinal bleeding was related to the prognosis of younger patients, while choline esterase was related to the prognosis of advanced age. Regression analysis after stratified MELD score showed that age and hypertension were related to the prognosis of patients with MELD score < 20, and treatment method and age were related to the prognosis of patients with MELD score≥20. Conclusion:Artificial liver treatment is beneficial for the 1-year prognosis of ACLF patients. Age, MELD score, hypertension, and upper gastrointestinal bleeding are independent risk factors affecting the prognosis of ACLF patients.

Objective: To investigate the diagnostic value of serum α-enolase (ENO1) in the primary hepatocellular carcinoma. Methods: From May 2012 to March 2017, 163 cases with liver diseases who met the inclusion and exclusion criteria were admitted to the Infectious Diseases Department of the General Hospital of Ningxia Medical University. Among them, 28 cases were of chronic hepatitis B (CHB), 31 cases with liver cirrhosis (LC), 104 cases with hepatocellular carcinoma (HCC), and 18 healthy volunteers (NC). Patient data and serum samples were collected and liver disease related indicators were measured to detect ENO1 levels with enzyme-linked immunosorbent assay (ELISA). The measured indicators were expressed in median. Mann-Whitney U nonparametric test was used to analyze the differences between the data. A Spearman’s correlation analysis was used for bivariate correlation analysis. The sensitivity and specificity of ENO1 and alpha-fetoprotein in the diagnosis of liver cancer were analyzed by ROC curve. Results: Serum level of ENO1 in CHB group, LC group and HCC group was significantly higher than normal group. Serum level of ENO1 in HCC group was higher than CHB group (P = 0.001) and LC group (P < 0.01). Area under the curve (AUC) for serum ENO1 and alpha-fetoprotein were 0.782 (cut-off value 75.96, P = 0.000 1) and 0.800 (cut-off value 27.02, P = 0.000 1), respectively. There was a positive correlation between ENO1 and AFP (P = 0.001). The combined detection had significantly improved the detection efficiency (AUC = 0.835). Serum ENO1 was statistically significant (P < 0.05) in HCC tumor size (AUC = 0.663), tumor metastasis (AUC = 0.681), TNM stage (AUC = 0.710, stage I vs. II), and Edmondson grade (AUC = 0.685) (P < 0.05) and the elevated levels of ENO1 had significantly reduced (P < 0.05) the survival time. Conclusion ENO1 can be a new candidate marker for the diagnosis of early stage HCC and its progression.

This study was aimed to investigate the influence on component content indexes,which included chlorogenic acid and luteolin of honeysuckle by the absorption of chemical insecticide thiamethoxam.High-performance liquid chromatography (HPLC) method was used in the analysis of content determination of component content indexes of honeysuckle samples by different concentrations of thiamethoxam.SPSS was used in the statistical analysis.The results showed that compared to samples from the blank control group,the content of chlorogenic acid had the increasing tendency in the honeysuckle groups with different concentrations of thiamethoxam.However,there was no significant difference among different experiment groups.There was no significant difference on luteolin among honeysuckle groups with different concentrations of thiamethoxam and the blank control group.It was concluded that at the recommended dose and high-powered dose of thiamethoxam,there was some influence on the content of chlorogenic acid.However,there was no significant effect on the content of luteoloside.And the quality scores of both contents were within the range defined in the Chinese Pharmacopoeia(2010 edition).

This article was aimed to study the dynamics of biocontrol endobacteria in roots, stems and leaves of Panax ginseng and soils adjacent roots. Gradient screening and root irrigation methods were used to develop Rif-resistance bacteria and inoculation. Dilution plate method was used to count the number of them in roots, stems and leaves of P. ginseng and soils adjacent roots. The results showed that bacteria which can endure 120 μg·mL-1 Rif was developed, and no change was found on their antagonistic activity against A lternaria panax Whetz and Phytophthora cactorum. In roots and stems of P. ginseng, ge15 and ge25 showed the highest number in the initial.Then, populations of ge15 and ge25 in ginseng roots and stems decreased to a stable status gradually. In ginseng leaves, populations of ge15 and ge25 increased to the highest 3 days after inoculation, then, populations of them were decreased and kept at certain concentration. In ginseng rhizosphere soil, populations of ge15 showed reciprocating change, and which of ge25 showed increase initial, and then decrease to a stable status. It was concluded that endobacteria can keep a certain population in ginseng roots, stems, and leaves. Biocontrol agents based on them will be helpful for ginseng diseases controlling in the field.

By nutrient solution culture method, effects of benzoic acid, diisobutyl phthalate, diisobutyl succinate, palmitic acid, 2,2-bis(4-hydroxyphenyl) propane on root exudates of Panax ginseng were studied. GC-MS results in-dicated that, 15 to 23 components were detected in treatments including control, which were organic acids, alcohol, amino acid esters, phenols, amines, condensed nucleus, saccharine, etc. Through compared with control we found that, phenol and phenolic acids in root exudates increased in most of stress treatments. So we deduced that, the re-laxation of autotoxins from roots to outside environment was stimulated by autotoxins released into soil, and which ac-celerated the autotoxicity to ginseng seedlings.

In this study, endophytic bacteria were isolated from roots of P. ginseng by plate culture method, and as a result, 40 endophytic bacterial strains were isolated, Bacillus spp. and Pseudomonas spp. were predominant. By confront culture method, two antagonistic endophytic bacterial strain, ge15 (Stenotrophomonas maltophilia) and ge25 (Bacillus sp. ) against Cylindrocarpon destructans, Sclerotinia schinseng and Alternaria pana were identified. The inhibition zone of ge15 to them were 5.5, 22.0, 14.8 mm, respectively; and which were 12.7,16.5,9.0 mm for ge25. The Results indicate that endophytic bacteria have biocontrol potential on ginseng pathogens, and which can be used as a bio-control factor on ginseng soilborne diseases control.
