BACKGROUND:Traditional Chinese medicine has rich experience and unique advantages in the empirical treatment of phlegm-heat and Fu-organs excess syndrome of ischemic stroke.In order to further explore the therapeutic targets and mechanisms of traditional Chinese medicine for this disease,it is crucial to establish a stable and reliable animal model of phlegm-heat and Fu-organs excess syndrome combined with empirical symptoms of ischemic stroke. OBJECTIVE:To explore the establishment method and evaluation system of the rat model of ischemic stroke with phlegm-heat and Fu-organ excess syndrome. METHODS:Sixty male Sprague-Dawley rats were randomly divided into four groups:blank control group(n=12),ischemic stroke group(n=18),disease+syndrome group(n=18),phlegm-heat and Fu-organ excess syndrome group(n=12),all of which were given high-fat diet for 25 days.On the 26th day,the rats in the blank control group and ischemic stroke group were intragastrically given normal saline and high fat diet,while those in the other two groups were intragastrically given autologous feces suspension and high fat diet for 3 continuous days.After gavage,ischemic stroke models were established using the suture method in the ischemic stroke group and disease+syndrome group.The changes in diet,water intake,body mass,body temperature,fecal traits,nasal secretions,sputum in the throat,and tongue image were recorded.Neurological deficits,tongue image,blood lipid levels,morphological changes of brain tissue and carotid artery,and the serum levels of motilin and somatostatin were detected. RESULTS AND CONCLUSION:Compared with the control group,the rats in the disease+syndrome group had shortness of breath,listlessness,irritability,bradykinesia,a large number of secretions around the nose,audible and heavy sputum in the throat,decreased diet and water intake,increased body mass,body temperature,and slingual vein score,decreased fecal pellet count,Bristol score and fecal moisture content,increased serum total cholesterol,triglyceride,low-density lipoprotein and somatostatin levels,decreased motilin level,increased neurological deficit score,significant pathological changes of the carotid artery,and significant morphological changes of the brain tissue.The ischemic stroke group only showed pathological changes of ischemic brain tissue,without the characteristics of phlegm-heat and Fu-organ excess syndrome.The phlegm-heat and Fu-organ excess syndrome group could present with the typical characteristics of traditional Chinese medicine syndromes,without the pathological changes of brain tissue with ischemic stroke.To conclude,the compound modeling method of high-fat induction combined with suture method and autologous feces gavage can establish an animal model of ischemic stroke with phlegm-heat and Fu-organ excess syndrome.

OBJECTIVE: To evaluate the effectiveness of early internal fixation combined with free anterolateral thigh perforator flap (ALTPF) transplantation in the treatment of open ankle fracture-dislocation. METHODS: A retrospective analysis was performed on the clinical data of 13 patients with open ankle fracture-dislocation who were admitted and met the inclusion criteria between January 2021 and May 2024. Among them, there were 9 males and 4 females, with the ages ranging from 23 to 61 years (mean, 45.3 years). Fracture types included 5 cases of simple medial or lateral malleolar fracture-dislocation, 7 cases of bimalleolar (medial and lateral) fracture-dislocation, and 1 case of trimalleolar fracture-dislocation. Additionally, 3 cases were complicated with bone defects (1 medial malleolus defect and 2 lateral malleolus defects). All injuries were classified as type ⅢB according to the Gustilo-Anderson classification for open fractures. The size of wound defects ranged from 7 cm×5 cm to 18 cm×12 cm. The time from injury to surgery was 2-20 hours (mean, 4 hours). All patients underwent emergency thorough debridement upon admission. The fracture-dislocation was temporarily stabilized with an external fixator, and the wound was covered with antibiotic-impregnated bone cement sheets or vacuum sealing drainage. Definitive internal fixation of the fracture and free ALTPF transplantation were performed 5-7 days after the initial emergency procedure. Postoperatively, wound healing, flap survival, and fracture union were monitored. At last follow-up, clinical outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score. RESULTS: All 13 patients were followed up 6-24 months (mean, 8.2 months). All flaps survived completely, and all fractures achieved union, with an union time of 3-11 months (mean, 5.5 months). One patient developed a superficial infection at the wound margin, which healed after regular dressing changes and drainage. No internal fixation-related complication (e.g., deep infection, implant loosening, or secondary ankle instability) were observed. At last follow-up, the total AOFAS ankle-hindfoot score was 78.6±13.5, with 3 excellent, 7 good, 2 fair, and 1 poor cases, yielding an excellent and good rate of 76.9%. CONCLUSION Early internal fixation combined with ALTPF transplantation for open ankle fracture-dislocation can shorten the treatment course and maximize the recovery of ankle joint function.

【Objective】 To investigate the status quo of disease perception and partner support of erectile dysfunction (ED) patients, and to analyze their correlation. 【Methods】 With convenient sampling method, 220 ED patients in a first-class hospital in Taiyuan were surveyed with the short version of disease perception questionnaire (BIPQ) and partner support coping questionnaire (DCI). 【Results】 The BIPQ score was (41.90±7.33), and the DCI score was (116.79±20.37). Pearson correlation analysis showed that except life influence, treatment control and emotional influence, the mutual support dimension of partner support of ED patients was correlated with all dimensions of disease perception (r=-0.173, 0.151, -0.182, 0.163, 0.188,P<0.05).Except cognitive comprehension, the negative support dimension of partner support of ED patients was correlated with the dimensions and total score of disease perception (r=0.399, 0.185, -0.167, -0.306, 0.269, 0.445, 0.320, 0.357,P<0.05). 【Conclusion】 ED patients have negative disease perception, and their partners have better coping strategies. Medical staff may pay more attention to partner support so as to reduce patients’ negative perception of disease and promote recovery.

Nuclear receptor corepressor (NCoR1) interacts with various nuclear receptors and regulates the anabolism and catabolism of lipids. An imbalance in lipid/energy homeostasis is also an important factor in obesity and metabolic syndrome development. In this study, we found that the deletion of NCoR1 in intestinal epithelial cells (IECs) mainly activated the nuclear receptor PPARα and attenuated metabolic syndrome by stimulating thermogenesis. The increase in brown adipose tissue thermogenesis was mediated by gut-derived tricarboxylic acid cycle intermediate succinate, whose production was significantly enhanced by PPARα activation in the fed state. Additionally, NCoR1 deletion derepressed intestinal LXR, increased cholesterol excretion, and impaired duodenal lipid absorption by decreasing bile acid hydrophobicity, thereby reversing the possible negative effects of intestinal PPARα activation. Therefore, the simultaneous regulatory effect of intestinal NCoR1 on both lipid intake and energy expenditure strongly suggests that it is a promising target for developing metabolic syndrome treatment.

Objective To investigate the effects of the rhein on the mitochondria fission and epithelial-mesenchymal transition(EMT)of breast cancer cells MDA-MB-231.Methods Human breast cancer cells were intervened with rhein,and the cells were divided into control group(0 μmol·L-1),low dose rhein group(100 μmol·L-1),and high dose rhein group(200 μmol·L-1).The proliferation activity of the cells was detected by CCK-8,and migrations was detected by Scratch-healing migration assay.The morphology and distribution of mitochondria were detected by transmission electron microscope,and the expression levels of Dynamin-related protein 1(Drp1),mitofusin2(Mfn2),E-cadherin,Vimentin proteins were detected by Western blot.Results Compared with control group,Rhein significantly reduced the protein expression of Drp1、Vimentin(P<0.05),and increased E-cadherin and Mfn2,thus down-regulating mitochondria fission,inhibiting cell proliferation and migration.High dose Rhein was better than low dose.Conclusion Rhein can inhibit the proliferation and migration of breast cancer cells by reducing the expression of Drp1,Vimentin and up-regulating Mfn2,E-cadherin proteins.

Chronic pain can develop from acute pain, and it is not only difficult to cure, but also easy to develop secondary psychological problems and negative emotions such as anxiety and depression, and the hippocampal plays a vital role in chronic pain. The morphological and functional changes in the hippocampus mediate the development and maintenance of chronic pain. This review focuses on the role of hippocampal abnormalities in chronic pain in recent years, in order to provide new ideas for the treatments of chronic pain and related dysthymic disorder complications in the future.

Objective:To investigate the association between the expression of long non-coding RNA genes and the HULC rs7763881 polymorphism, recurrence, and metastasis after radical resection in patients with hepatocellular carcinoma (HCC).Methods:Paraffin tissue samples were selected from 426 cases diagnosed with HCC between January 2004 to January 2012. The expression of different genotypes of HULC gene locus rs7763881 in paraffin tissues was detected by PCR, and the association between different genotype expressions and clinical case characteristics of HCC [gender, age, TNM stage, alpha-fetoprotein, tumor maximum diameter (cm), vascular invasion, tumor capsule, tumor grade] was analyzed. Cox proportional risk regression model was used to analyze the correlation between different genotypes and clinicopathological features, prognosis, and recurrence. Survival analysis between different genotypes was performed using the Kaplan–Meier method for a parallel log-rank test.Results:There were 27 (6.3%) cases in the whole group who lost to follow-up. A total of 399 (93.7%) specimens were included in the study, and 105 (26.3%), 211 (52.9%) and 83 (20.8%) were included in the rs77638881 AA, AC, and CC genotypes, respectively. Kaplan-Meier curve showed that the postoperative overall survival and recurrence-free survival rate were significantly higher in patients with the AA than AC/CC genotype ( P < 0.05). Univariate analysis showed that the AC/CC genotype was closely related to tumor vascular invasion and recurrence or metastasis of HCC ( P < 0.05). Cox multivariate analysis results showed that patients with the AA genotype were taken as references, and the results showed that the risk of recurrence and metastasis in patients with the CA/CC genotype increased to varying degrees, with statistical significance ( P < 0.05). Conclusion:The rs7763881 polymorphic loci located on the HULC gene are closely related to HCC recurrence and metastasis after radical resection. Thus, it may be an indicator for evaluating HCC recurrence and metastasis.

This study reported the diagnosis and treatment of cytochrome P450 oxidoreductase deficiency (PORD) in a male infant. The patient was admitted to Children's Hospital Affiliated to Shandong University at the age of 38 days due to nasal obstruction and feeding difficulties presented at 10 d after birth, as well as less weight gain. Physical examination showed craniosynostoses, hand and foot deformities, and normal external genitalia. Laboratory examination revealed mildly elevated serum adrenocorticotrophic hormone and decreased level of baseline cortisol. A homozygous mutation of c.1370G>A(p.R457H) in POR gene was detected by whole-exome sequencing, which confirmed the diagnosis of PORD. Skeletal deformities complicated by external genital malformations and/or adrenocortical hormone abnormalities are important diagnostic indicators for PORD.
