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.

OBJECTIVE To mine the adverse drug event （ADE） signals of selinexor， and to provide reference for its clinical safety medication. METHODS ADE data for selinexor reported from July 3rd， 2019 to March 31st， 2023 were collected from the FDA adverse event reporting system （FAERS）. Data mining was performed by using the reporting odds ratio （ROR） and proportional reporting ratio （PRR） methods， and categorization statistics were performed by using the system organ class （SOC） and preferred term （PT） from drug ADE terminology set in the MedDRA （version 26.0）. RESULTS A total of 3 084 ADE reports were obtained for selinexor， with a total of 134 ADE-positive signals. Among the reported genders， there were 127 males and 124 females， with a predominant age of ≥65 years old （4.12%）； the United States had the highest number of reports （96.53%）， with consumers being the main reporters （77.27%）； severe ADR was mainly characterized by hospitalization/prolonged hospitalization （26.26%）， followed by death （17.15%）. The top 3 ADE in the list of frequency were nausea （1 162 times）， fatigue （790 times） and anorexia （610 times）， all of which were mentioned in the selinexor’s instructions. The top 3 signals in the list of strength were device-associated bacteremia （ROR＝115.07， PRR＝114.94）， blepharospasm dysfunction （ROR＝106.70， PRR＝106.54）， and salmonella sepsis （ROR＝99.90， PRR＝99.81）， all of which were not mentioned in the selinexor’s instructions. CONCLUSIONS In addition to the ADE of nausea mentioned in the instruction manual， attention should also paid to device-associated bacteremia， blepharospasm dysfunction， salmonella sepsis， and other ADE not mentioned in the instruction manual when using selinexor in clinical practice； weekly rechecking of the patient’s blood routine should be done to monitor the patient’s blood indexes， symptoms of infection， and so on， to ensure that the safety of 1661962346@qq.com drug use.

Objective In order to explore the influence and effect of case teaching method based on real patients in oto-rhinolaryngology on clinical practice ability of general practice.Methods 96 trainees of general practice in otolaryngology de-partment from January 2018 to January 2021 were randomly divided into two groups:a CBL group and a control group.In the CBL group,CBL teaching method was adopted based on real patients in Otorhinolaryngology.Conventional teaching method was used in the control group.Results The theoretical scores of written test and the examination of clinical skill operation scores of the CBL group and the control group were analyzed.There was significant difference between the two groups(P＜0.05).The students in CBL group were more satisfied with clinical thinking ability,analysis and problem solving ability,active learning abil-ity,learning efficiency,teacher-student interaction,doctor-patient communication ability and consultation skills than the control group.There was significant difference between the two groups(P＜0.05).Conclusion The CBL teaching method can obvi-ously improve the learning enthusiasm and clinical practice ability of general resident training doctors.The teaching quality has been significantly improved.It is of great value to cultivate excellent general practitioners.

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.

Grip strength, 6-meter walking speed and 5-times sit to stand test were conducted by experienced team members.Skin autofluorescence was used to detect skin AGEs.A portable optical scanner was used to detect heavy metals and trace elements using reference points of the palm.Levels of fasting blood glucose, glycosylated hemoglobin, high-density lipoprotein and other common blood biochemical indicators were measured.Results:A total of 106 subjects were enrolled, including 68 in the young and middle-aged group and 38 in the elderly group.The proportion of patients with hypertension(14 ases or 36.8% vs.7 ases or 10.3%), systolic blood pressure[130(120, 140) vs.120(110, 126)mmHg], fasting blood glucose[5.7(5.2, 5.9)mmol/L vs.5.2(4.9, 5.5)mmol/L], glycosylated hemoglobin[6.0(5.7, 6.2)% vs.5.7(5.4, 5.9)%], 8-oxoGsn/Cre[1.9(1.4, 2.6) vs.1.3(1.0, 1.6)], AGEs(2.44±0.46 vs.2.01±0.29), 5-times sit to stand test scores[7.8(6.9, 9.8)s vs.6.0(5.0, 6.8)s], magnesium(31.4±7.2 vs.27.7±6.4), mercury(0.013±0.003 vs.0.008±0.003)and silver[0.011(0.010, 0.012) vs.0.010(0.009, 0.011)]were higher in the elderly group than in the young and middle-aged group, while grip strength[28.0(22.0, 35.1)kg vs.36.6(28.5, 49.1)kg], fat-free mass[44.9(37.5, 51.1)kg vs.53.3(42.4, 58.5)kg], trunk muscle mass[21.0(17.5, 23.9)kg vs.25(19.8, 27.4)kg], appendicular skeletal muscle mass[20.9(17.6, 23.9)kg vs.24.9(19.8, 27.3)kg], calcium[273.3(219.1, 480.0) vs.457.8(428.5, 489.1)], cobalt[0.029(0.027, 0.031) vs.0.031(0.028, 0.034)], selenium[1.44(0.93, 1.71) vs.1.61(1.53, 1.68)]and nickel[3.5(3.3, 4.0)*10 -3vs.3.8(3.6, 4.1)*10 -3]were lower in the elderly group than in the young and middle-aged group( P<0.05). Urinary 8-oxoGsn/Cre levels were positively correlated with age, time of 5-times sit to stand test, AGEs, fasting blood glucose, mercury and aluminum( rs=0.443, 0.292, 0.357, 0.205, 0.316 and 0.214, P<0.05), and negatively correlated with trunk muscle mass, appendicular skeletal muscle mass, fat-free mass, grip strength, silicon and manganese( rs=-0.334, -0.333, -0.332, -0.366, -0.246 and -0.234, P<0.05), with statistical significance. Conclusions:Increased urinary 8-oxoGsn/Cre levels are correlated with decreased muscle mass, poor physical function, accumulation of AGEs, decreased trace element levels and increased heavy metal levels.Therefore, 8-oxoGsn has the potential to be a broadly representative and sensitive indicator for health assessment.

Objective:To study on the effects of gastrointestinal function and portal vein hemodynamics applicated with abdominal hot compressing with evodiae fructus and crude salt after hepatectomy.Methods:A total of 60 patients who underwent hepatectomy were randomly divided into 2 groups by random number table method, with 30 in each group. The control group was treated with conventional basic western medicine, while the treatment group was treated with medicinal evodiae fructus and crude salt hot compress on abdomen on the basis of the control group. The portal vein diameter (PVD), portal venous flow velocity (PVV), recovery time of main clinical indexes, clinical symptom scores and liver function indexes were dynamically monitored at different observation time points.Results:The scores of abdominal distension, nausea and vomiting in the treatment group were significantly lower than those in the control group 3 days after treatment ( t values were -3.489 and -2.740, respectively, all Ps<0.05). The recovery time of bowel sounds, first exhaust time and first defecation time in the treatment group were significantly earlier than those in the control group ( t values were -3.622, -4.297 and -4.151, respectively, all Ps<0.01). With the extension of treatment time, ALT in 2 groups showed a gradual downward trend ( P<0.05 or P<0.01), DBIL in control group was significantly higher at 3 days after treatment than before ( t=-2.157, P=0.039), and TBIL was significantly lower at 7 days after treatment than before ( t=2.175, P=0.038). The PVD ( t values were 3.528, 2.160) and PVV ( t values were 11.096, 4.264) of the treatment group were significantly higher than those of the control group 3 and 5 days after treatment ( P<0.01 or P<0.05). Conclusion:Early application of abdominal hot compressing with evodiae fructus and crude salt hot compress on abdomen after hepatectomy can improve the portal vein blood circulation and promote the rehabilitation of gastrointestinal function in patients with hepatectomy.

Objective:To review the imaging characteristics and evaluate the diagnostic value of Doppler echocardiography for congenitally malposition of septum primum(MSP).Methods:Images of Doppler echocardiography were retrospectirely rewiewed and compared with CTA, operative and necropsy findings in 8 cases with MSP in Xinhua Hospital, and Shanghai Children′s Medical Center, Shanghai Jiaotong University School of Medicine from January 2009 to October 2019.Results:MSP was characterized by the absent of superior limbic band of septum secundum and different degrees of the leftward deviation of septum primum, and the pulmonary veins which connected with the posterior wall of the anatomical left atrium incorporated intothe right atrium. The associated malformations included totally anomalous (7 cases) and partially anomalous (1 case) pulmonary venous drainage directly to the right atrium. Six of 8 cases were diagnosed correctly. In the remaining 2 cases, 1 case misdiagnosed as single atrium, and the other case misdiagnosed as cor triatriatum.Conclusions:MSP could be diagnosed accurately by Doppler echocardiography. This malformation should be distinguished from single atrium and cor triatriatum.
