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 investigate the safety and efficacy of posterior apical total intervertebral release (IVR) combined with posterior column osteotomy (PCO) in the treatment of rigid scoliosis.Methods:This study retrospectively analyzed the clinical and radiographic data of 27 patients with rigid scoliosis who underwent posterior total IVR combined with PCO in the apical region from July 2017 to September 2023. There were 10 males and 17 females with an age of 19.3±8.8 years (range 11-48 years). Among them, there were 16 cases of idiopathic scoliosis, 7 cases of neuromuscular scoliosis, 1 case of congenital scoliosis, 1 case of Marfan syndrome with scoliosis, 1 case of neurofibromatosis with scoliosis, and 1 case of osteogenesis imperfecta with scoliosis. The mean Cobb angle of the main curve was 75.4°±13.7° (range 58.7°-110.2°) preoperatively. The mean flexibility of the main curvature is 15.7%±4.7% (range 2.5%-24.3%). Preoperative computer tomography showed that the area of the IVR channel in the convex and concave side of the apical region was 128.1±23.3 mm 2 and 89.5±18.6 mm 2, respectively. The area of the convex IVR was significantly higher than that of the concave IVR. Results:All 27 patients underwent surgery successfully. Total IVR was performed at an average of 3.4±0.7 levels in the apical region. SPO and Ponte osteotomy were performed at 2.7±0.7 and 4.9±1.1 levels, respectively. The mean fusion segment is 11.2±2.0. The operation time, estimated blood loss, and follow-up time were 7.5±0.9 hours (range 6.0-9.8 hours), 1 103.7±845.1 ml (range 300-4 500 ml), and 20.0±14.2 months (range 5-56 months), respectively. The preoperative, postoperative, and final follow-up's mean coronal Cobb angles of the main curve were 75.4°±13.7°, 18.2°±6.5° and 18.6°±6.5°, respectively. The mean correction rate was 75.7%±5.3%. In cases of thoracolumbar kyphosis, the preoperative, postoperative, and final follow-up mean sagittal Cobb angles were 47.2°±4.7°, 22.8°±9.1° and 23.8°±8.9°, respectively. The mean correction rate was 49.5%±18.9%. The mean axial vertebral rotation (AVR) in the IVR region was 24.6°±7.6° preoperatively and was corrected to 11.6°±5.6° postoperatively. The mean correction rate for AVR was 54.0%±11.3%. The coronal, sagittal Cobb angles and AVR postoperatively were significantly lower than those preoperatively ( P<0.001). This case series reported 4 cases of postoperative pleural effusion and 1 case of pulmonary infection, and all of them were cured through conservative treatment. One patient developed incision infection 2 months postoperatively and recovered through debridement surgery. Two patients had proximal junctional kyphosis, one of them underwent revision surgery, and another case was treated with braces. Conclusion:Posterior multi-segment total IVR combined with PCO is a safe and effective surgical procedure for the treatment of rigid scoliosis. The procedure of total IVR was recommended as a supplement for better release of the rigid spine when traditional release methods are not effective.

Objective·To analyze infertility couples,dyadic coping level by using latent profile analysis(LPA),and explore the heterogeneity and related factors of different profiles.Methods·From September to November 2023,257 newly diagnosed infertility couples in pre-infertility treatment with assisted reproductive technology(ART)were recruited from Reproductive Medicine Center,Renji Hospital,Shanghai Jiao Tong University School of Medicine.All couples were evaluated by using general information questionnaire,Fertility Problem Inventory(FPI),Dyadic Coping Inventory(DCI),and Fertility Quality of Life(FertiQoL)Tool.LPA was used to explore the dyadic coping profiles of the couples before ART treatment,and general information,FPI scores and FertiQoL scores were compared among the profiles.Multinomial Logistic regression analysis was used to explore the related factors of different profiles.Results·A total of 257 couples with infertility were included,with an average age of(30.15±3.07)years for females,(31.82±3.82)years for males,(3.75±2.16)years for marriage,and(2.90±1.92)years for infertility;there were 118 couples caused by male infertility,109 couples caused by female infertility,and 30 couples caused by both infertility;the average DCI score for males was(128.25±19.15)points,while for females it was(129.91±18.32)points.According to the dyadic coping levels,the infertile couples were divided into four profiles:common positive coping group(153 couples,59.5％),common negative coping group(85 couples,33.1％),male positive coping group(12 couples,4.7％),and male negative coping group(7 couples,2.7％).There were statistically significant differences in the infertile couples'age,FPI score,FertiQoL score,and remarriage rate among the four profiles(P＜0.05).Multinomial Logistic regression analysis results showed that,with the common positive coping group as the reference,the common negative coping group had older men(OR=1.122,95％CI 1.004-1.254,P=0.036),higher FPI scores for both males and females(male:OR=1.019,95％CI 1.003-1.035,P=0.018;female:OR=1.020,95％CI 1.004-1.036,P=0.015),and lower FertiQol scores for males(OR=0.966,95％CI 0.937-0.996,P=0.029).Conclusion·There are four types of dyadic coping profiles in infertile couples before ART treatment.Compared with the common positive coping couples,higher reproductive pressure,elder age,and lower perceived fertility quality of life of males,and higher reproductive pressure of females are all risk factors for common negative coping couples.

Objective·To explore the effect of a prehospital multimodal prehabilitation program on the preoperative functional status and postoperative recovery of patients with gastrointestinal malignant tumors.Methods·A total of 78 patients with gastrointestinal malignant tumors,hospitalized in Shanghai General Hospital,Shanghai Jiao Tong University School of Medicine from June to December 2023,were enrolled.They were divided into the standard group(SD group,n=40)and the prehospital multimodal prehabilitation group(PMP group,n=38)by using random number table.From the time the operation was agreed upon by both the doctor and patient to the day before the operation,the SD group followed the routine preoperative guidance,while the PMP group received a home-based prehospital multimodal prehabilitation program.The general data of patients were collected,and the six-minute walk distance(6MWD)was compared between the two groups at baseline and on the day before operation.The length of postoperative hospitalization,time to first flatus,time to first ambulation,time to first oral intake,drainage removal time and postoperative complication rate were also compared between the two groups.Results·There was no difference in general data and duration of preoperative intervention of patients between the two groups.At baseline,there was no significant difference in 6MWD between the two groups.On the day before operation,the 6MWD in the PMP group was higher than that in the SD group(P=0.016).Changes in 6MWD in the PMP group were significantly higher compared to SD group during the preoperative period,with values of(23.42±13.59)m vs.(-3.75±12.08)m(P＜0.001).Time to first flatus,time to first ambulation and time to first oral intake in the PMP group were earlier than those in the SD group(P＜0.05).However,there was no significant difference in drainage removal time,postoperative hospitalization and postoperative complication rate between the two groups(P＞0.05).Conclusion·Prehospital multimodal prehabilitation can improve the preoperative function and accelerate the postoperative recovery in patients with gastrointestinal malignancies.

Objective To explore the activation of tumor necrosis factor-α(TNF-α)signaling pathway and the expressions of the associated inflammatory factors in NPHP1-defective renal tubular epithelial cells.Methods A human proximal renal tubular cell(HK2)model of lentivirus-mediated NPHP1 knockdown(NPHP1KD)was constructed,and the expressions of TNF-α,p38,and C/EBPβ and the inflammatory factors CXCL5,CCL20,IL-1β,IL-6 and MCP-1 were detected using RT-qPCR,Western blotting or enzyme-linked immunosorbent assay.A small interfering RNA(siRNA)was transfected in wild-type and NPHP1KDHK2 cells,and the changes in the expressions of TNF-α,p38,and C/EBPβ and the inflammatory factors were examined.Results NPHP1KDHK2 cells showed significantly increased mRNA expressions of TNF-α,C/EBPβ,CXCL5,IL-1β,and IL-6(P<0.05),protein expressions of phospho-p38 and C/EBPβ(P<0.05),and IL-6 level in the culture supernatant(P<0.05),and these changes were significantly blocked by transfection of cells with siRNA-C/EBPβ(P<0.05).Conclusion TNF-α signaling pathway is activated and its associated inflammatory factors are upregulated in NPHP1KDHK2 cells,and C/EBPβ may serve as a key transcription factor to mediate these changes.

Objective To optimize the method of combining azomethane oxide(AOM)and dextran sodium sulfate(DSS)to create a colitis-associated colon cancer(CAC)model,and to explore the pathogenesis of the intestinal flora in CAC.Methods Model groups A and B were established by one and two injections of AOM,respectively,combined with free drinking of DSS,and a normal control group was injected intraperitoneally with normal saline combined with purified water(n=10 mice per group).The better modeling scheme was selected by comprehensive evaluation of the disease activity index score,colon length,tumor rate,and mortality.Serum levels of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),and tumor markers CA199,CEA,and CA724 were detected by enzyme-linked immunosorbent assay.Colon lesions were evaluated by hematoxylin and eosin(HE)staining.Changes in the intestinal microbiota in CAC mice were detected by 16S rDNA high-throughput gene sequencing analysis of mouse feces.Results Both single and enhanced AOM injections combined with DSS induced CAC mice;however,colon growths were larger,more closely arranged,and their morphological size was more consistent in group B compared with group A,with a tumor-formation rate of 100％.IL-6 levels were increased in the model group compared with the normal group(P＜0.05).TNF-α levels were increased in the model group compared with the normal group(P＞0.05).The CA199 and CEA levels were also significantly increased(P＜0.05),but CA724 levels were not.Infiltration of inflammatory cells in the colon detected by HE pathology was accompanied by high-grade intraepithelial tumor-like changes on the surface of the lumen.The diversity and abundance of intestinal bacteria were decreased in CAC mice compared with normal mice:phyla Verrucomicrobiota and Actinobacteriota were significantly increased(P＜0.05),Bacteroidota and Campilobacterota were significantly decreased(P＜0.05).Akkermansia,Prevotellaceae,Ruminococcus,and Bifidobacterium were significantly increased(P＜0.05),and Roseburia,Rikenellaceae_RC9_gut_group,Anaeroplasma,and Muribaculaceae were significantly decreased(P＜0.05).Conclusions Two injections of AOM combined with 1.5％(1.5 g/100 mL)DSS induced CAC model mice with a high colon-tumorigenesis rate,uniform tumor morphology,and low mortality,and may thus be the preferred modeling scheme for pharmacodynamic experiments.Disorders or dysfunction of the intestinal flora may lead to increased permeability,loss of intestinal mucosal barrier function,and the release of enterogenic endotoxins,Resultsing in a sustained inflammatory response,as an indirect or direct cause of CAC pathogenesis.

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.

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.
