Objective: To establish a real-time quality control scheme based on the median (MD-IC) of internal control cycle threshold value in negative samples (NEG-IC-CT), so as to monitor anomalies such as progressive drift in nucleic acid testing system not covered by conventional internal quality control (IQC) in blood center nucleic acid laboratories, and to verify its feasibility. Methods: The internal control CT values of 54 426 negative samples were retrospectively collected. These samples were from four reagent batches of the two new and old equipment sets during the operation of the Wantai nucleic acid testing system in our blood center. The daily median of NEG-IC-CT values was used as the research indicator. Control limits were calculated using median absolute deviation (MAD) to construct the Median-MAD quality control chart. The monitoring performance of this scheme for the operation status of the testing system was simultaneously evaluated. Results: Statistical analysis showed significant differences in NEG-IC-CT value distribution between the new and old equipment sets, as well as between the two different reagent batches of the old equipment (P<0.000 1). The NEG-IC-CT value performance of the two different reagent batches of the new equipment was no significant difference in distribution (P>0.05). This scheme identified three typies of distinct anomalies. The out-of-control events observed with the old equipment in both the O1 and O2 reagent batches suggested potential performance decay due to equipment aging. The unreported change of reagent batch in time of Phase B with new equipment caused a stepwise drift on the quality control chart. In the later stage of Phase A with the new equipment, an alert was triggered, indicating potential quality risks associated with practices such as the mixed use of the remaining reagents and extremely long operator working hours. Conclusion: The realtime quality control scheme based on NEG-IC-CT value established in this study has been preliminarily validated for its monitoring effectiveness in nucleic acid testing in our blood center. This scheme performed well in detecting differences among testing systems and reagent batches, serving as an effective supplement to routine internal quality control. It can provide an intuitive and effective evaluation method for monitoring the performance of the nucleic acid testing process at blood center.

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.

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.

BACKGROUND:Currently,traditional Chinese medicine has accumulated extensive experience in the treatment and management of ischemic stroke.The application of latent structure combined with association rule analysis to deeply explore and summarize the"medicine-prescription-syndrome"rules is conducive to promoting the optimization of ischemic stroke prevention and treatment strategies.OBJECTIVE:To explore the rules of Chinese medicine in the treatment of ischemic stroke,and provide a reference for the clinical treatment of ischemic stroke based on syndrome differentiationMETHODS:A systematic search was conducted for clinical research literature on traditional Chinese medicine treatment of ischemic stroke from China National Knowledge Infrastructure(CNKI),WanFang,VIP,and SinoMed databases,covering the period from January 1,1990,to August 15,2024.The relevant studies were selected and the data were extracted into an Excel 2019 database for analysis.The frequency of use of Chinese herbs,their properties,meridional tropism,therapeutic effects and associated syndromes were analyzed.High-frequency herbs(＞4％)were subjected to latent structure modeling,comprehensive clustering,and association rule analysis using Lantern 5.0 and RStudio software,followed by summary of medication patterns and potential traditional Chinese medicine syndromes for ischemic stroke.RESULTS AND CONCLUSION:(1)A total of 231 articles were included,involving 203 kinds of traditional Chinese medicine,and the frequency of use was 2 524 times.(2)The high-frequency Chinese herbs were Chuanxiong,Earthworm,Angelica,Astragalus,Salviorrhiza,red peony root,safflower,leech,peach kernel,and pinellia.These herbs had predominantly warm,cold,or neutral properties,with bitter,sweet,and pungent flavors.Primary meridional tropism targets the liver,spleen and heart.Drug for invigorating blood circulation and eliminating stasis,deficiency tonifying drug,calming liver wind drug,expectorant cough suppressant and anti-asthmatic drug were used more frequently.(3)The latent structure model analysis identified 7 latent variables,14 latent classes,6 comprehensive clustering models,and 19 core prescriptions.It is hypothesized that the main traditional Chinese medicine syndromes for ischemic stroke are qi deficiency and blood stasis syndrome,wind-phlegm obstructing the channels syndrome,phlegm and blood stasis obstructing the channels syndrome,and phlegm-heat obstructing the viscera syndrome.(4)The association rule analysis revealed 29 strongly associative rules,including 2 two-item rules and 27 three-item rules.The highest degree of support was Angelica-Chuanxiong,and the highest degree of confidence was Angelica+licorice-Chuanxiong.The results show that ischemic stroke is a syndrome with qi and blood deficiency,liver and kidney Yin deficiency as the root causes,and wind,phlegm,blood stasis,and fire as the manifestations.The treatment is mainly to benefit qi and strengthen health,promote blood circulation and remove blood stasis,combined with pathological factors such as"phlegm and heat,""qi stagnation,""Yin deficiency,"and"liver fire,"supplemented by clearing heat and phlegm,promoting qi stagnation,nourishing liver and kidney,clearing liver and reducing fire.

Pediatric urological non-Hodgkin lymphoma is relatively rare.When a single renal or ureteral tumor with multiple lymph node or bone metastases is present, it is very easy to be misdiagnosed as urinary tumor with metastasis, resulting in unnecessary radical nephrectomy. This paper reports two cases of non-Hodgkin lymphoma presenting with single urinary nodules. Case 1 was diagnosed with a 4.5cm tumor in the right kidney due to fever and fatigue. CT and PET-CT showed multiple bone destruction and lymph node metastasis. Renal biopsy was performed and ALK-positive anaplastic large cell lymphoma was diagnosed. Chemotherapy was effective for 6 months. Case 2 was diagnosed with left hydronephrosis due to intermittent low back pain for 2 weeks. Ultrasound examination revealed ureteral dilation with left hydronephrosis and low echo occupying of the lower ureter. The patient had sudden blurred vision before surgery. MRI examination revealed space occupying in the right optic nerve frame, and PET-CT found multiple bone, lymph nodes and nerve invasion. A lymph node biopsy was performed and Burkitt lymphoma was diagnosed. After 6 months of chemotherapy and radiotherapy, the tumor shrank significantly.

【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.
