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 explore the current situation and influencing factors of quality of life of septic patients in intensive care unit (ICU) after discharge, and to provide theoretical basis for clinical early psychological intervention and continuity of care.Methods:A prospective observational study was conducted. The septic patients who were hospitalized in the department of critical care medicine of the Affiliated Hospital of Jining Medical University and discharged with improvement from January 1 to December 31, 2022 were selected as the research objects. The demographic information, basic diseases, infection site, vital signs at ICU admission, severity scores of the condition within 24 hours after ICU admission, various biochemical indexes, treatment process, and prognostic indexes of all the patients were recorded. All patients were assessed by questionnaire at 3 months of discharge using the 36-item short-form health survey scale (SF-36 scale), the activities of daily living scale (ADL scale), and the Montreal cognitive assessment scale (MoCA scale). Multiple linear regression was used to analyze the factors influencing the quality of life of septic patients after discharge from the hospital.Results:A total of 200 septic patients were discharged with improvement and followed up at 3 months of discharge, of which 150 completed the questionnaire. Of the 150 patients, 57 had sepsis and 93 had septic shock. The total SF-36 scale score of septic patients at 3 months of discharge was 81.4±23.0, and the scores of dimensions were, in descending order, role-emotional (83.4±23.0), mental health (82.9±23.6), bodily pain (82.8±23.3), vitality (81.6±23.2), physical function (81.4±23.5), general health (81.1±23.3), role-physical (79.5±27.0), and social function (78.8±25.2). There was no statistically significant difference in the total SF-36 scale score between the patients with sepsis and septic shock (82.6±22.0 vs. 80.7±23.6, P > 0.05). Incorporating the statistically significant indicators from linear univariate analysis into multiple linear regression analysis, and the results showed that the factors influencing the quality of life of septic patients at 3 months after discharge included ADL scale score at 3 months after discharge [ β= 0.741, 95% confidence interval (95% CI) was 0.606 to 0.791, P < 0.001], length of ICU stay ( β= -0.209, 95% CI was -0.733 to -0.208, P = 0.001), duration of mechanical ventilation ( β= 0.147, 95% CI was 0.122 to 0.978, P = 0.012), total dosage of norepinephrine ( β= -0.111, 95% CI was -0.044 to -0.002, P = 0.028), mean arterial pressure (MAP) at ICU admission ( β= -0.102, 95% CI was -0.203 to -0.007, P = 0.036) and body weight ( β= 0.097, 95% CI was 0.005 to 0.345, P = 0.044). Conclusions:The quality of life of patients with sepsis at 3 months after discharge is at a moderately high level. The influencing factors of the quality of life of patients with sepsis at 3 months after discharge include the ADL scale score at 3 months after discharge, the length of ICU stay, the duration of mechanical ventilation, the total dosage of norepinephrine, MAP at ICU admission and body weight, and healthcare professionals should enhance the treatment and care of the patients during their hospitalization based on the above influencing factors, and pay attention to early psychological intervention and continued care for such patients.

ObjectiveTo induce the rat model of ulcerative colitis （UC） with spleen-kidney Yang deficiency and liver depression， and explore the efficacy and mechanism of Sishenwan combined with Tongxie Yaofang （SSW&TXYF） based on the therapeutic principles of tonifying spleen， soothing liver， warming kidney， and astringing intestine. MethodSixty male SD rats were randomized into normal， model， mesalazine， and high-， medium-， and low-dose SSW&TXYF groups. The rats in other groups except the normal group were administrated with Sennae Folium decoction and hydrocortisone and received tail clamping for 14 days. On day 14， rats received enema with TNBS-ethanol solution to induce UC. The rats were administrated with corresponding drugs from day 15 of modeling， and the body weight and mental state were observed and recorded. The sucrose preference test was performed from day 25. On day 28， the rectal temperature was measured， and the rats were administrated with 3% D-xylose solution at a dose of 10 mL·kg^-1 by gavage. Blood was sampled 1 h later， from which the serum was collected for measurement of the D-xylose content. The serum， hippocampus， and colorectum samples of rats were collected on day 29. The levels of gastrin （GAS）， adrenocorticotropic hormone （ACTH）， corticosterone （CORT）， cyclic adenosine monophosphate （cAMP）， cyclic guanosine monophosphate （cGMP）， interleukin （IL）-4， tumor necrosis factor （TNF）-α， and interferon （IFN）-γ in the serum and 5-hydroxytryptamine （5-HT） in the hippocampus were determined by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was employed to reveal the colonic lesions. The mRNA and protein levels of p38 mitogen-activated protein kinase （MAPK）， extracellular signal-regulated kinase （ERK）， and c-Jun N-terminal kinase （JNK） in the colon tissue were determined by Real-time PCR and Western blot， respectively. ResultCompared with the normal group， the model group showed decreased body weight， anal temperature， and D-xylose content in the serum and increased GAS content （P<0.01）. The modeling led to cAMP/cGMP unbalance and decreased the ACTH and CORT content in the serum （P<0.01）， the preference for sucrose water， and the 5-HT content in the hippocampus （P<0.01）. Moreover， it shortened the colorectal length and caused massive infiltration of inflammatory cells and severe structural damage in the colon tissue. High， medium， and low doses of SSW&TXYF improved above indicators （P<0.05， P<0.01）， reduced inflammatory infiltration， and repaired the pathological damage of the tissue. Compared with the normal group， the model group showed lowered IL-4 level （P<0.01） and elevated TNF-α and IFN-γ levels （P<0.05， P<0.01） in the serum， as well as up-regulated expression of p38 MAPK， ERK， and JNK （P<0.05， P<0.01）. Compared with the model group， SSW&TXYF elevated the IL-4 level （P<0.01）， lowered the TNF-α and IFN-γ levels （P<0.05， P<0.01）， and down-regulated the mRNA and protein levels of p38 MAPK， ERK， and JNK （P<0.05， P<0.01）. ConclusionA rat model of UC with spleen-kidney Yang deficiency and liver depression was successfully established. SSW&TXYF can significantly mitigate this syndrome by reducing the inflammatory response in the colon and inhibiting the MAPK pathway.

Objective: To study the association between 24 h activities and Fundamental Motor Skills (FMS) among children with autism spectrum disorder (ASD) using compositional data analysis, and the expected changes in FMS after isochronous substitution of each activity, in order to provide reference basis for improving FMS levels in children with ASD. Methods: From October 2023 to April 2024, a total of 301 children with ASD aged 6-10 from 7 special education schools in Jinan, were investigated by cluster random sampling, and 24 h movement behaviors were calculated based on accelerator data. Test of Gross Motor Development- 2 was used to assess FMS. R software was used to perform the descriptive statistical, multiple linear regression and isochronous substitution analyses. Results: The proportion of moderatevigorous physical activity (MVPA) in children with ASD was positively related with FMS scores, locomotor, and object control skills ( β=12.42, 6.32, 6.10, P <0.01). Reallocating 15 min from sleep (SLP) to MVPA resulted in respective increases of 3.66, 1.91, and 1.75 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from sedentary behavior (SB) to MVPA resulted in respective increases of 3.72, 1.88 , and 1.83 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from light physical activity (LPA) to MVPA resulted in respective increases of 3.32, 1.57, and 1.74 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Moreover, reallocating 15 min from SB to LPA resulted in an increase of 0.28 points in locomotor skills ( P <0.05). Dose response analysis revealed that substitution of MVPA for SLP, SB, and LPA in children with ASD enhanced their FMS levels, and their substitution was asymmetrical; and substitution of LPA for SB enhanced locomotor skills level. Conclusions Among the 24 h movement behaviors, increasing the time spent on MVPA and LPA have positive impacts on the FMS of children with ASD. Schools and families should optimize the allocation of 24 h activity time in children with ASD, so as to promote the improvement of FMS levels of children with ASD.

OBJECTIVE To study the fingerprint of Denghong buyang huanwu granules （DBHG）， screen the quality markers， and establish the method for content determination of active ingredients. METHODS HPLC method was adopted. The fingerprints of 10 batches of DBHG （S1-S10） were established by using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 edition）， and similarity evaluation was also performed. Traditional Chinese medicine pieces attribution analysis， cluster analysis （CA）， principal component analysis （PCA） and orthogonal partial least squares discriminant analysis （OPLS-DA） were conducted for common peaks， and quality biomarkers were screened based on variable importance projection （VIP） values＞1. The contents of 10 batches of samples were determined by the same HPLC method， such as salidroside， tyrosol， calycosin-7-O-beta-D-glucoside， scutellarin and calycosin. RESULTS A total of 25 common peaks were obtained in the fingerprints for 10 batches of samples and 6 common peaks were identified， i.e. salidroside， tyrosol， paeoniflorin， calycosin-7-O-beta-D-glucoside， scutellarin， calycosin. Their similarities were greater than 0.9， and 10 common peaks of them were unique components of Erigeron breviscapus. DBHG could be clustered into 2 categories by using CA and PCA； S4-S5， and S7 could be clustered into one category and other samples could be clustered into one category. The corresponding components of peaks 16 （scutellarin）， 12， 15 （calycosin-7-O-beta-D-glucoside）， 13 （paeoniflorin）， and 14 were quality markers. The average contents of salidroside， tyrosol， calycosin-7-O-beta-D-glucoside， scutellarin and calycosin were 1.64， 0.45， 0.31， 0.73， 0.15 mg/g in 10 batches of samples. CONCLUSIONS HPLC fingerprint for DBHG and a method for determining the contents of five active ingredients including salidroside are successfully established. Five quality markers have been screened. It can be used for the quality control of the preparation.

ObjectiveTo construct a mouse model of inflammation-associated colorectal cancer （CAC） by using azoxymethane （AOM）/dextran sulfate sodium （DSS） and investigate the effect of Huangqintang on the gut microbiota structure of mice during the occurrence and development of CAC by 16S rRNA gene high-throughput sequencing. MethodA total of 225 C57BL/6J mice were randomized into 5 groups （n=45）： Normal， model， positive drug （mesalazine）， and high （18 g·kg^-1） and low （9 g·kg^-1）-dose Huangqintang. Except those in the normal group， each mouse was injected with 10 mg·kg^-1 AOM on day 1 and day 5 within 1 week and then given 1.5% DSS solution for 7 days， which was then changed to sterile water for 14 days. This process referred to as one cycle， and mice were treated for a total of 3 cycles. On the first day of DSS treatment， mice were administrated with corresponding drugs by gavage， and the normal group and the model group were administrated with pure water by gavage， once a day until the end of the third cycle. The progression of CAC was divided into inflammation， proliferation， and tumorigenesis stages. At the end of each cycle， the body weight and colon length were measured for mice in each group， and the number of colon tumors in mice was recorded. Meanwhile， the disease activity index （DAI） was determined. The serum levels of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and carbohydrate antigen-199 （CA199）， a tumor marker in the gastrointestinal tract of mice， were measured by ELISA. Hematoxylin-eosin staining was employed to observe colon lesions. At the same time， 3-5 pellets of fresh feces of mice in the normal group， model group， and high-dose Huangqintang group were collected， from which the fecal DNA of mice was extracted for 16S rRNA gene high-throughput sequencing. ResultCompared with the normal group， the model group showed decreased body weight （P<0.01）， increased DAI， and shortened colon length （P<0.05） at the three stages. Compared with the normal group， the model group showed elevated levels of IL-1β， IL-6， and TNF-α （P<0.05） at the proliferation stage and elevated levels of CA199 at the inflammation， proliferation， and tumorigenesis （P<0.01） stages. Compared with the normal group， the model group presented obvious infiltration of inflammatory cells at the inflammation stage， thickening of the muscle layer and abnormal proliferation of mucosal layer cells at the proliferation and tumorigenesis stages， and final formation of advanced intraepithelial tumor lesions. Compared with the model group， the Huangqintang groups showed no significant improvement in the body weight， decreased DAI score， and increased colon length at the three stages， and the increase of colon length in the tumorigenesis stage was significant （P<0.01）. At the tumorigenesis stage， the administration of Huangqintang inhibited tumor formation and growth， reduced the number of tumors （P<0.01）， lowered the levels of IL-6 （P<0.05， P<0.01）， TNF-α （P<0.05， P<0.01）， and IL-1β at the three stages， and decreased CA199 at the inflammation stage as well as at the proliferation and tumorigenesis stages （P<0.01， P<0.05）. Compared with the model group， the administration of Huangqintang reduced inflammation and abnormal cell proliferation， delaying the occurrence of tumors. Compared with the normal group， the model group showcased decreased alpha and beta diversity and altered structure of gut microbiota at the inflammation， proliferation， and tumorigenesis stages. The administration of Huangqintang adjusted the abundance and diversity of gut microbiota to the normal levels. At the inflammation stage， Huangqintang positively regulated two differential phyla （Firmicutes and Bacteroidetes） and three differential genera （Muribaculaceae， Rikenellaceae_RC9_gut_group， and Flavonifractor） in mice. At the proliferation stage， Huangqintang positively regulated two differential phyla （Bacteroidetes and Patescibacteria） and five differential genera （Muribaculaceae， Rikenellaceae_RC9_gut_group， Candidatus_Saccharimonas， norank_f__UCG-010， and Allobaculum）. At the tumorigenesis stage， Huangqintang positively regulated two differential phyla （Proteobacteria and Patescibacteria） and eight differential genera （Muribaculaceae， Candidatus_Saccharimonas， norank_f_UCG-010， Lachnospiraceae_UCG-006， Allobaculum， Bacteroides， Lachnospiraceae_NK4A136_group， and Flavonifractor） in mice. ConclusionHuangqintang can intervene in the AOM/DSS-induced transformation of inflammation to CAC in mice by correcting inflammation and short-chain fatty acid-related microbiota disorders.

Objective To analyze the correlation between serum miR-939 and miR-15b expression and mi-crovascular injury in patients with diabetic retinopathy(DR).Methods A total of 176 patients with type 2 di-abetes diagnosed and treated in the Baoding Second Hospital from January 2021 to October 2022 were selected as the study objects.The subjects were divided into 74 patients without DR(NDR group),62 patients with non-proliferative DR(NPDR group)and 40 patients with proliferative DR(PDR group)according to whether or not DR occurred and the degree of lesions.Real-time fluorescent quantitative PCR was used to detect the relative expression levels of miR-939 and miR-15b in serum of all groups,the level of vascular endothelial growth factor(VEGF)was detected by enzyme-linked immunosorbent assay,and the count percentage of en-dothelial cells(ECs),endothelial progenitor cells(EPCs)and circulating progenitor cells(CPCs)was detected by flow cytometry.Serum levels of miR-939,miR-15b,VEGF and ECs,EPCs and CPCs were compared in 3 groups.Pearson correlation was used to analyze the correlation between serum miR-939 and miR-15b and VEGF,ECs,EPCs and CPCs.Multivariate Logistic regression was used to analyze the factors affecting the oc-currence of DR in patients with type 2 diabetes.Results The relative expression levels of miR-939 and miR-15b in PDR group and NPDR group were lower than those in NDR group,while the serum VEGF levels were higher than those in NDR group,with statistical significance(P＜0.05).ECs in PDR group and NPDR group were higher than those in NDR group,while EPCs and CPCs were lower than those in NDR group,the differ-ence was statistically significant(P＜0.05).Serum miR-939 was negatively correlated with VEGF and ECs(r=-0.407,-0.613,P＜0.05),and positively correlated with EPCs and CPCs(r=0.481,0.486,P＜0.05).Serum miR-15b was negatively correlated with VEGF and ECs(r=-0.539,-0.625,P＜0.05),and positively correlated with EPCs and CPCs(r=0.451,0.483,P＜0.05).Multivariate Logistic regression anal-ysis showed that the duration of type 2 diabetes,hemoglobin A1c,2-hour postprandial blood glucose,VEGF,miR-939 and miR-15b were the influencing factors for the occurrence of DR in type 2 diabetes patients(P＜0.05).Conclusion The expression of miR-939 and miR-15b in serum of DR patients is closely related to VEGF,ECs,EPCs and CPCs,and the expression of miR-939 and miR-15b in serum of DR patients can provide a certain reference for early judgment and evaluation of the degree of microvascular injury.

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 investigate the characteristics of imaging signs of giant cell tumor(GCT)of the hand and foot bones.Methods The clinical,X-ray,CT and MRI images of 18 cases of GCT of hand and foot bones diagnosed by pathology were analyzed retrospectively.And compared with 54 cases of long bone GCT imaging manifestations.Results Among the 18 GCT cases of hand and foot bones,there were 8 cases of hand,10 cases of foot,including 12 cases of short tubular bone and 6 cases of tarsal bone.All lesions were dilatant osteolytic bone destruction involving the joint surface,in which the short tubular bone GCT showed central growth,the tumor occupied the entire wide diameter of the bone,the lesion range was long,consistent with the bone axis,easy to invade the surrounding soft tissue,sclerotic edge,bone ridge,lobed and periosteal reaction were rare,and prone to recurrence after surgery.The GCT of tarsal bone and short tubular bone showed eccentric growth,and there was statistical difference(P<0.05).The probability of pathological fracture in GCT of long bone was significantly greater than that of short tubular bone.There was no significant difference between the two groups in swelling growth,involvement of bone end and ethmoid sign of bone cortex.Conclusion Compared with long bone GCT,hand and foot bones are rare occurrence site of GCT,which is more aggressive than long bone GCT and prone to recurrence after surgery.Full attention should be paid to its imaging characteristics to provide more accurate image information for clinical treatment strategies.
