Hepatic encephalopathy is a difficult and critical disease with rapid progression and limited treatment methods in the field of liver disease， and it is urgently needed to make breakthroughs in its pathogenesis. Selection of appropriate prevention and treatment strategies is of great importance in delaying disease progression and reducing the incidence and mortality rates. This article reviews the theory of “turbid toxin pathogenesis” and related prevention and treatment strategies for hepatic encephalopathy in traditional Chinese medicine/Zhuang medicine， proposes a new theory of “turbid toxin pathogenesis”， analyzes the scientific connotations of “turbid”， “toxin”， and the theory of “turbid toxin pathogenesis”， and constructs the “four-step” prevention and treatment strategies for hepatic encephalopathy， thereby establishing the new clinical prevention and treatment regimen for hepatic encephalopathy represented by “four prescriptions and two techniques” and clarifying the effect mechanism and biological basis of core prescriptions and techniques in the prevention and treatment of hepatic encephalopathy， in order to provide a reference for the prevention and treatment of hepatic encephalopathy.

End-stage liver diseases,such as cirrhosis and liver cancer caused by hepatitis B,are often combined with hepatic encephalopathy(HE);ammonia poisoning is posited as one of its main pathogenesis mechanisms.Ammonia is closely related to autophagy,but the molecular mechanism of ammonia's regulatory effect on autophagy in HE remains unclear.Sialylation is an essential form of glycosylation.In the nervous system,abnormal sialylation affects various physiological processes,such as neural development and synapse formation.ST3 β-galactoside α2,3-sialyltransferase 6(ST3GAL6)is one of the significant glycosyltransferases responsible for adding α2,3-linked sialic acid to substrates and generating glycan structures.We found that the expression of ST3GAL6 was upregulated in the brains of mice with HE and in astrocytes after ammonia induction,and the expression levels of α2,3-sialylated glycans and autophagy-related proteins microtubule-associated protein light chain 3(LC3)and Beclin-1 were upregulated in ammonia-induced astrocytes.These findings suggest that ST3GAL6 is related to autophagy in HE.Therefore,we aimed to determine the regulatory relationship between ST3GAL6 and autophagy.We found that silencing ST3GAL6 and blocking or degrading α2,3-sialylated glycans by way of Maackia amurensis lectin-Ⅱ(MAL-Ⅱ)and neuraminidase can inhibit autophagy.In addition,silencing the expression of ST3GAL6 can downregulate the expression of heat shock protein β8(HSPB8)and Bcl2-associated athanogene 3(BAG3).Notably,the overexpression of HSPB8 partially restored the reduced autophagy levels caused by silencing ST3GAL6 expression.Our results indicate that ST3GAL6 regulates autophagy through the HSPB8-BAG3 complex.

BACKGROUND:Early identification of patients requiring ventilator support will be beneficial for the outcomes of botulism.The present study aimed to establish a new scoring system to predict mechanical ventilation(MV)for botulism patients. METHODS:A single-center retrospective study was conducted to identify risk factors associated with MV in botulism patients from 2007 to 2022.Univariate analysis and multivariate logistic regression analysis were used to screen out risk factors for constructing a prognostic scoring system.The area under the receiver operating characteristic(ROC)curve was calculated. RESULTS:A total of 153 patients with botulism(66 males and 87 females,with an average age of 43 years)were included.Of these,49 patients(32.0%)required MV,including 21(13.7%)with invasive ventilation and 28(18.3%)with non-invasive ventilation.Multivariate analysis revealed that botulinum toxin type,pneumonia,incubation period,degree of hypoxia,and severity of muscle involvement were independent risk factors for MV.These risk factors were incorporated into a multivariate logistic regression analysis to establish a prognostic scoring system.Each risk factor was scored by allocating a weight based on its regression coefficient and rounded to whole numbers for practical utilization([botulinum toxin type A:1],[pneumonia:2],[incubation period≤1 day:2],[hypoxia<90%:2],[severity of muscle involvement:grade II,3;grade III,7;grade IV,11]).The scoring system achieved an area under the ROC curve of 0.82(95%CI 0.75-0.89,P<0.001).At the optimal threshold of 9,the scoring system achieved a sensitivity of 83.7%and a specificity of 70.2%. CONCLUSION:Our study identified botulinum toxin type,pneumonia,incubation period,degree of hypoxia,and severity of muscle involvement as independent risk factors for MV in botulism patients.A score≥9 in our scoring system is associated with a higher likelihood of requiring MV in botulism patients.This scoring system needs to be validated externally before it can be applied in clinical settings.

Objective To investigate the impact of SARS-CoV-2 infection on male semen quality through meta-analysis and retrospec-tive study.Methods Literature retrieval was conducted in PubMed,CNKI,Wanfang Database and CBM database.Meta-analysis was performed using Stata 15.0.The male patients meeting the inclusion criteria from our hospital were enrolled as study subjects.General demographic data and semen parameters were collected.Single factor analysis of variance and graphing of semen parameters were con-ducted using GraphPad Prism 9.5.1.The test level was set at 0.05.Results A total of 9 studies involving 267 patients were included in the meta-analysis.There were no significant differences in sperm concentration and survival rate before and after SARS-CoV-2 infec-tion(P＞0.05).Semen volume and percentage of normal morphology significantly increased during 1-3 months after infection(P=0.005,P=0.010),with semen volume recovering to pre-infection level＞3 months later(P＞0.05).Sperm motility and progressive mo-tility increased＞3 months after infection(P=0.046,P=0.045),recovering to pre-infection levels(P=0.099,P=0.098).Sperm DNA fragmentation index may be temporarily elevated within 3 months after infection but gradually decreased＞3 months later.In the retrospective study of 8 cases,there were no statistical differences in semen parameters at different stages compared with pre-infection(P＞0.05),but semen parameters showed a negative trend during＜1 month after infection and recovered to pre-infection levels＞3 months later.Conclusion The results of this laboratory study are basically consistent with the meta-analysis.SARS-CoV-2 infection in males only caused short-term negative effects on sperm morphology,vitality and DNA integrity,but generally recovered to pre-infection levels＞3 months after infection.Due to the limitations of study subjects and sample size,the impact of SARS-CoV-2 infection on male semen quality needs to be further confirmed by long-term large-scale prospective studies.

Objective:To explore the mediating effect of perceived organizational support on the relationship between personality traits and perceived self-efficacy of male nurses.Methods:A total of 766 male nurses from 20 level-A general hospitals in Shandong province were selected by convenience sampling method in December 2020. The general status questionnaire, the simplified version of Big Five Personality Inventory, the Perceived Organizational Support Scale and the General Self-efficacy Scale were used to investigate them.Results:The total score and average item score of 766 male nurses' sense of organizational support was 44.05±9.31, 3.38±0.72, and the total score and average item score of general self-efficacy was 26.19±5.65, 2.62±0.57. In 766 male nurses, perceived organizational support had a partial mediating effect on neuroticism and openness, with effect values of 21.71% and 10.19%, respectively. In addition, perceived organizational support had a complete mediating effect on conscientiousness and self-efficacy.Conclusions:The organizational support and self-efficacy of 766 male nurses were above average, and organizational support played a mediating role in the relationship between neuroticism, openness, conscientiousness and general self-efficacy.Nursing managers should give more organizational support to male nurses to change the influence of neuroticism, responsibility, agreeableness and open personality traits on self-efficacy, so as to improve the level of self-efficacy of male nurses.

Objective:To investigate of AIDET communication model in caring for type 2 diabetes mellitus of hospitalized patients.Methods:A total of 113 patients with type 2 diabetes mellitus treated in our department from January 2018 to November 2019 were enrolled, and divided into the control group(receiving a conventional communication mode)and the observation group(receiving an AIDET communication mode)according to a time order in the selecting of the research patients.The changes of self-care behavior and glucose metabolism index were evaluated and analyzed between the two groups.Results:On admission, the fasting blood glucose, 2-h postprandial blood glucose and glycosylated hemoglobin were(9.1±1.7)mmol/L, (13.8±2.9)mmol/L and(8.4±3.5)% in the observation group, and(9.4±2.1)mmol/L, (14.1±3.2)mmol/L and(8.1±2.9)% in the control group, respectively, with no statistically significances( P>0.05). At discharge, the observation group versus the control group showed a statistically significantly improved levels in FPG of(5.9±1.5)mmol/L vs.(7.8±1.9)mmol/L, in 2h-PBG of(10.1±3.7)mmol/L vs.(12.8±3.9)mmol/L and in glycosylated hemoglobin of(6.3±1.2)% vs.(7.5±0.9)%, respectively( P<0.05). The scores of management of poor blood glucose, foot care, blood glucose monitoring, medication compliance, regular exercise and diet control were higher in the observation group than in the control group at discharge( P<0.05). Conclusions:The application of AIDET communication mode can effectively enhance the self-care behavior of patients and help improve the glucose metabolism in hospitalized patients with type 2 diabetes mellitus.It has very positive effects on controlling the development of type 2 diabetes mellitus and improving the quality of life.

Objective    To investigate the characteristics and prognostic value of cellular immune function in severe patients with coronavirus disease 2019 (COVID-19). Methods    A cohort study was conducted to collect the clinical data of 119 severe patients admitted to the Renmin Hospital of Wuhan University (Eastern District) including 60 males (50.4%) and 59 females (49.6%), with an average age of 60.9±14.2 years. The primary endpoint of follow-up was death in the hospital, and the disease outcome classification was the secondary endpoint of follow-up within 30 days after admission. We analyzed the correlation between cellular immune function and COVID-19 prognosis. Results     A total of 22 patients died during this process, and 47 patients were severe/critical during the follow-up period. The counts of CD3+, CD4+, CD8+, and CD19+ in the primary endpoint events were significantly different between the survival group and the death group (all P<0.05). The counts of CD3+, CD4+, CD8+, CD19+ in the secondary endpoint events were significantly different between the normal group and the severe/critical group (all P<0.05). The results of the receiver operating characteristic (ROC) curve showed that the area under the cellular immune function curve of dead patients and severe/critical patients had good predictive value (all P<0.05). Conclusion    Cell immune function has good clinical and prognostic value for COVID-19.
