ObjectiveTo investigate the changes in coagulation system in acute decompensated cirrhosis （ADC） patients with or without sepsis and the association of these changes with short-term prognosis. MethodsA prospective study was conducted among 116 ADC patients who were hospitalized in Nanfang Hospital from January 2021 to July 2023， among whom there were 86 patients with sepsis and 30 patients without sepsis， and 54 patients with sepsis alone who had no chronic liver disease were enrolled as control group. Thromboelastography （TEG） and other conventional coagulation parameters were used to comprehensively evaluate the coagulation function of patients. The data including TEG results and short-term prognosis were collected， and a correlation analysis was performed. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. The Spearman correlation coefficient was calculated to investigate the correlation between different variables. The Logistic regression model was used to perform the univariate and multivariate analyses. ResultsFor the ADC patients with sepsis， the lungs and bloodstream were the main infection sites， and bacteria were the main pathogenic microorganism. TEG results showed that compared with the patients with sepsis alone， the patients with ADC and sepsis had a significant reduction in median maximum amplitude （MA）， a significant increase in coagulation time （K time）， and a significant reduction in α angle （all P<0.05）； the patients with ADC and sepsis had a significantly longer reaction time （R time） than those with ADC alone （P=0.02）， and the patients with sepsis alone had a significantly longer R time than those with ADC and sepsis （P=0.04）. There was no correlation between MA and platelet count in the patients with ADC and sepsis （r=-0.133， P=0.057）， while there was a significant correlation between MA and platelet count in the patients with sepsis alone （r=0.595， P=0.001）. SOFA score was negatively correlated with MA in sepsis patients with or without ADC （r=-0.503 and -0.561， both P<0.001）， and for the patients with ADC and sepsis， R time， K time， and α angle were weakly correlated with SOFA score and had a relatively strong correlation with APTT （all P<0.05）. The patients with ADC alone all survived within 90 days， and compared with the death group， the patients with sepsis alone who survived had significantly higher values of MA and α angle （all P<0.05）； there was a significant difference in α angle on day 90 between the survival group and the death group， no matter whether the patients were comorbid with ADC or not （both P<0.01）， while for the patients with ADC and sepsis， there was no significant difference in MA value on day 90 between the survival group and the death group （P>0.05）. ConclusionFor ADC patients comorbid with sepsis， coagulation function assessment and monitoring should be taken seriously in clinical practice， and TEG parameters and SOFA score should be monitored when necessary to develop individualized treatment regimens.

BACKGROUND:Erythropoietin has anti-inflammatory,anti-apoptotic,and pro-bone defect repair effects.To date,fewer studies have been conducted on its effects and molecular mechanism underlying restorative dentin formation after pulp injury. OBJECTIVE:To explore the effect of erythropoietin on restorative dentin formation after pulp injury. METHODS:(1)Animal experiment:Thirty-two rats were randomly divided into control group(n=16)and experimental group(n=16).In the experimental group,collagen sponges containing erythropoietin were used to directly cap the pulp at the pulp injury,and in the control group,collagen sponges containing PBS were used to directly cap the pulp at the exposed pulp injury.The cavity was then closed with glass ionomer adhesive.After 2 and 4 weeks of treatment,the maxillary bones of the two groups were collected,and the expression of nestin in dentin was detected by immunohistochemistry,and the reparative dentin production was observed by hematoxylin-eosin staining.The maxillae of four Sprague-Dawley rats were taken for immunohistochemical detection of erythropoietin expression in molar and incisor teeth.(2)Cell experiment:Human dental pulp cells,human periodontal ligament cells and human gingival fibroblasts were obtained from human dental tissue,periodontal ligament,and gingival tissue.Real-time reverse transcription PCR(RT-PCR)was used to detect the mRNA expression of erythropoietin.Erythropoietin,dentin sialophosphoprotein,dentin matrix protein 1,and nestin mRNA levels in human pulp cells were detected by RT-PCR under induced or uninduced odontoblastic differentiation.After down-regulation of erythropoietin expression or exogenous administration of erythropoietin intervention under induced or uninduced differentiation odontoblastic differentiation,the relative mRNA expression of dentin sialophosphoprotein and dentin matrix protein 1 in human pulp cells was detected by RT-PCR,and the formation of mineralized nodules was detected by alizarin red S staining,and mRNA and protein expressions of bone morphogenetic protein 2 were detected by RT-PCR and western blot,respectively. RESULTS AND CONCLUSION:(1)Animal experiment:Compared with the control group,the restorative dentin production and nestin expression were higher in the experimental group after 2 and 4 weeks of treatment.The expression of erythropoietin was weakly positive in pulp,odontoblastic cell layer and periodontal membrane of the rat's first maxillary molar,and strongly positive in odontoblasts.(2)Cell experiment:The mRNA expression of erythropoietin was higher in human dental pulp cells than in the other two types of cells.The mRNA expressions of dentin sialophosphorin,dentin matrix protein 1,nestin,erythropoietin and bone morphogenetic protein 2 in human pulp cells increased and the formation of mineralized nodules during odontoblastic differentiation under induction compared with non-induction conditions.The mRNA expression of dentin sialophosphoprotein,dentin matrix protein 1,nestin,bone morphogenetic protein 2 and the formation of mineralized nodules were decreased in human pulp cells after downregulation of erythropoietin under induced odontoblastic differentiation,and the protein expression of bone morphogenetic protein 2 was also decreased.After exogenous erythropoietin intervention,the expression of the above indexes in human dental pulp cells increased.To conclude,erythropoietin can promote the formation of dentin to some extent.

Objective:To report the blood group antigen and antibody specificity identification methods for a patient with high-frequency antibodies, and the process of finding and providing compatible blood for the patient.Methods:A patient sent from the Blood Transfusion Department of Shanxi Provincial People′s Hospital to Taiyuan Blood Center in November 2022 was selected for the study. Classical serological methods were used to determine the patient′s blood type, screen for unexpected antibodies, identify antibodies, and perform crossmatching. High-frequency antibody identification was carried out using red blood cells treated with various enzymes. Blood group genotyping was conducted using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF) and Sanger sequencing. Multiple strategies were employed to address the patient′s blood source problem. The study was approved by the Medical Ethics Committee of Taiyuan Blood Center [Ethics No. 2024 Ethics Review No.(2)].Results:①The patient′s blood type was B, RhD positive. Initial screening of the patient′s serum with multiple screening cells and antibody identification cells in saline medium was negative, but positive in antiglobulin medium. The patient′s serum showed varying reaction intensities with red blood cells treated with different enzymes. ②MALDI-TOF mass spectrometry and Sanger sequencing revealed a homozygous nonsense variant c. 376C>T (p.Gln126Ter) in the ABCG2 gene, resulting in the Jr(a-) phenotype. During family donor selection, the patient′s son was found to have a heterozygous variant c. 376C>T (p.Gln126Ter), and another heterozygous variant c. 421C>A (p.Gln141Lys), which predicted a Jr(a+ w) phenotype. ③Crossmatch tests confirmed the compatibility of blood from the patient′s son, which was used to address the urgent blood requirement. Later, rare blood from a Jr(a-) donor from the Guangzhou Blood Center was used for the patient′s ongoing treatment, saving the patient′s life. Conclusion:Combining classic serological testing with blood group gene typing techniques successfully identified the rare Jr(a-) blood type and high-frequency anti-Jra antibodies. Enzyme-treated red blood cell identification methods confirmed the presence of anti-Jra antibodies. By searching within the family and seeking help from other blood centers, compatible blood was found. This approach may provide insights for resolving similar complex blood matching problems in the future.

Objective:To observe the effect of combining heat-sensitive moxibustion with action observation therapy in the treatment of spastic wrist and hand dysfunction post-stroke.Methods:Ninety stroke survivors with spasmodic wrist and hand dysfunction were randomly assigned to a heat-sensitive moxibustion group, an action observation group, or a combination group, each of 30. In addition to routine rehabilitation treatment, the groups received heat-sensitive moxibustion, action observation therapy or moxibustion followed by action observation therapy in 6 sessions a week over 6 weeks. Surface electromyography signals (iEMG and RMS) were recorded from the affected wrist and hand muscles before and after the treatment. All of the participants were also assessed using the Fugl-Meyer motor assessment for the upper extremities (FMA-UE).Results:After treatment, a significant improvement was observed in the average FMA-UE values, with that of the combination group (17.2±2.1) significantly higher than those of the other two groups. The average iEMG of the wrist flexors and extensors, the extensors of the fingers, and abductor pollicis brevis had increased significantly, with the combination group′s averages significantly higher than those of the other two groups. The average RMS values of those muscles had decreased significantly after the treatment, with those of the combination group significantly lower than the others.Conclusions:Combining heat-sensitive moxibustion and action observation therapy can significantly reduce muscle tension, and promote strength and better functioning of spastic wrist and hand muscles after a stroke. The combination is worthy of clinical application and promotion.

Objective:To explore the regulatory mechanisms underlying the weak expression of ABO blood group antigens due to variants in the non-coding regions of the ABO gene. Methods:From June 2014 to October 2023, a total of 29 samples from the Taiyuan Blood Center and local hospitals, which were serologically identified as having weak ABO antigen expression without detectable coding region mutations, were selected for this study. Full-length ABO gene sequencing was performed using third-generation long-read sequencing technology (Pacific Biosciences) to obtain complete haplotype sequences of the ABO gene. Variants in the non-coding regions were compared and identified to infer their regulatory effects on weak antigen expression. The procedures followed in this study were in accordance with the ethical standards of the World Medical Association′s Declaration of Helsinki (2013 revision). The Medical Ethics Committee of Taiyuan Blood Center has granted an exemption from ethical review. Results:18 bp deletions in the -35 to -18 region of the promoter were identified in 7 samples. Variants in intron 1 (+ 5.8 kb) were detected in 7 samples, including ABO* A (28+ 5792_5793delCT (1 case) and ABO* B (28+ 5793T>C) located in the GATA binding region; ABO* B (28+ 5808C>T) (1 case) in the E-box region; and ABO* B (28+ 5875C>T) (4 cases) in the RUNX1 binding region. Nucleotide variants at splice sites were detected in 2 samples, namely ABO* B (C.98+ 1G>A) and ABO* B (C.204-2A>C). Conclusion:Variants in the non-coding regulatory sequences of the ABO gene are a significant factor contributing to weak ABO antigen expression. In clinical ABO sequencing, it is essential to screen not only the conventional coding regions but also the flanking sequences, introns, and splice sites of the ABO gene to facilitate precise blood transfusion.

Objective To investigate the serum C-C motif chemokine ligand 27(CCL27)and laminin sub-unit gamma-2(LAMC2)levels and prognostic value before transurethral resection of bladder tumor(TURBT)in patients with non-muscle-invasive bladder cancer(NMIBC).Methods A total of 104 patients with NMIBC who underwent primary TURBT at the First Affiliated Hospital of Air Force Medical University from February 2019 to February 2021 were retrospectively selected as the NMIBC group,and another 50 healthy individuals who underwent physical examinations at the same hospital during the same period were se-lected as the control group.The levels of serum CCL27 and LAMC2 before TURBT in the two groups were detected by enzyme-linked immunosorbent assay.Kaplan-Meier curve was used to analyze the effect of serum CCL27 and LAMC2 before TURBT on the prognosis of NMIBC patients.COX regression was used to analyze the prognostic factors of patients with NMIBC.The receiver operating characteristic(ROC)curve was used to analyze the value of serum CCL27 and LAMC2 before TURBT in evaluating the prognosis of NMIBC pa-tients.Results The levels of serum CCL27 and LAMC2 in the NMIBC group before TURBT were higher than those in the control group,and the difference was statistically significant(P<0.05).The levels of serum CCL27 and LAMC2 before TURBT in patients with NMIBC at tumor stage T1 and high-grade pathological grade were higher than those in patients with tumor stage Ta/Tis and low-grade pathological grade,and the difference was statistically significant(P<0.05).The 3-year progression-free survival rate of patients in the high-level CCL27 group was lower than that in the low-level CCL27 group,and the difference was statistically significant(χ2=20.021,P<0.001).The 3-year progression-free survival rate of patients in the high-level LAMC2 group was lower than that in the low-level LAMC2 group,and the difference was statistically signifi-cant(χ2=11.012,P<0.001).Tumor stage T1,high-grade pathological grade,high level of serum CCL27,and high level of serum LAMC2 were risk factors affecting the prognosis of patients with NMIBC(P<0.05).The results of ROC curve analysis showed that the area under the curve and 95%CI of the combined serum CCL27 and LAMC2 before TURBT for the prognosis assessment of NMIBC patients were 0.901(0.881-0.925),which were larger than those of the single detection,and the difference was statistically significant(Z=4.620,4.912,P<0.001).Conclusion The elevated levels of serum CCL27 and LAMC2 before TURBT in NMIBC patients are related to the degree of tumor malignancy,and can serve as prognostic markers for in-dividualized treatment strategies.

Objective To investigate the effect of Shugan Lipi Prescription on patients with diarrhea-predominant irritable bowel syndrome(IBS-D)of liver stagnation and spleen deficiency type from the perspective of bile acid-intestinal flora axis imbalance.Methods From May 2022 to May 2023,a total of 122 patients with IBS-D of liver stagnation and spleen deficiency type admitted to the Xi'an No.9 Hospital were enrolled into the investigation.The patients were randomly divided into the control group and the observation group by random number table method,with 61 patients in each group.The control group was given conventional western medicine treatment with oral administration of Dicetel plus Compound Diphenoxylate Tablets and Bifidobacterium Quadruple Viable Tablets,and the observation group was treated with Shugan Lipi Prescription on the basis of treatment for the control group.One course of treatment covered seven days,and both groups were treated for four courses in total.The changes of Irritable Bowel Syndrome Symptom Severity Scale(IBS-SSS)score,levels of serum bile acid and the fecal levels of intestinal flora such as Bifidobacterium,Lactobacillus,and Enterococcus in the two groups of patients before and after treatment were observed.Moreover,the clinical efficacy and the incidence of adverse reactions during the treatment of the two groups were compared.Results(1)After four courses of treatment,the total effective rate of the observation group was 96.72%(59/61)and that of the control group was 83.61%(51/61),and the intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P<0.05).(2)After treatment,the scores of IBS-SSS items such as abdominal pain,abdominal pain duration,abdominal distension,defecation satisfaction and life interference in the two groups were all decreased when compared with those before treatment(P<0.05),and the decrease in the observation group was significantly superior to that in the control group(P<0.01).(3)After treatment,the levels of serum taurodeoxycholic acid(TDCA),taurocholic acid(TCA)and taurolithocholic acid(TLCA)in the two groups were decreased when compared with those before treatment(P<0.05),and the decrease in the observation group was significantly superior to that in the control group(P<0.01).(4)After treatment,the fecal level of Enterococcus,a kind of pathogenic bacterium,in both groups was decreased when compared with that before treatment(P<0.05),and the fecal levels of probiotics of Bifidobacterium and Lactobacillus in both groups were increased when compared with those before treatment(P<0.05).The effects on the decrease of fecal Enterococcus level and on the increase of fecal Bifidobacterium and Lactobacillus levels in the observation group were significantly superior to those in the control group(P<0.05 or P<0.01).(5)The incidence of adverse reactions in the observation group was 8.20%(5/61)and that in the control group was 6.55%(4/61),and the intergroup comparison showed that the difference was not statistically significant(P>0.05).Conclusion Shugan Lipi Prescription exerts certain therapeutic effect for IBS-D patients of liver stagnation and spleen deficiency type,and is with higher safety.Its therapeutic mechanism may be related to the restoration of the function of bile acid-intestinal flora axis.

Ischemic stroke （IS） is a cerebrovascular disease caused by thrombosis or embolism that interrupts cerebral blood flow， resulting in brain tissue damage. Mitochondria serve as the primary site for energy metabolism and are also involved in key biological processes， including calcium signal regulation， reactive oxygen species generation， and apoptosis initiation. Therefore， the structural and functional integrity of mitochondrial is crucial for neuronal survival， and the mitochondrial quality control （MQC） system is fundamental for maintaining mitochondrial homeostasis. The MQC system maintains mitochondrial network homeostasis by synergistically regulating key processes such as biogenesis， dynamics balance （fusion and fission）， autophagy， oxidative stress clearance， and calcium homeostasis. However， following IS， neurons undergo pathological changes-including inflammatory responses， oxidative stress， and excitatory amino acid toxicity- due to ischemia and hypoxia. These factors collectively disrupt mitochondrial membrane potential and inhibit electron transport chain function， leading to MQC dysfunction. Recent studies have confirmed that acupuncture can restore MQC homeostasis after IS through multiple targets and pathways， specifically including promoting mitochondrial biogenesis， balancing mitochondrial fission and fusion， regulating mitochondrial autophagy， reducing oxidative stress damage， and inhibiting calcium overload. This article systematically reviews the relationship between MQC and IS， with a focus on elucidating the mechanistic basis of acupuncture-mediated IS treatment via regulating key MQC components. These findings provide a theoretical basis for the efficacy of acupuncture in IS management and offer novel perspectives for developing future stroke therapeutic strategies targeting MQC pathways.

Objective:To investigate the current status of treatment delay and analyze its influencing factors in patients with breast cancer-related lymphedema.Methods:Using convenience sampling, 218 patients with breast cancer-related lymphedema from The First Affiliated Hospital of Zhengzhou University between April 2024 and January 2025 were enrolled. The General Information Questionnaire, Lymphedema Self-Management Support Scale for Breast Cancer Survivors (LSMS-BCs), Brief Illness Perception Questionnaire for Breast Cancer-related Lymphedema (BIPQ-BCRL), Perceived Barriers to Health Care-Seeking Decision-Chinese (PBHSD-C), and Health Literacy Scale for Chronic Patients (HLSCP) were used to conduct a cross-sectional survey. Logistic regression identified predictors of treatment delay, with model fit assessed by the Hosmer-Lemeshow test. Discriminative ability was evaluated using receiver operating characteristic (ROC) curve analysis.Results:The study included 218 female BCRL patients, aged (58.31 ± 10.54) years. Among 218 patients, 76 experienced treatment delay, the incidence of treatment delay was 34.8% (76/218). Independent risk factors included junior high school education or below, no regular arm circumference measurement, low self-management support scores, low illness perception scores, high perceived barriers to healthcare-seeking scores, and low health literacy scores (Wald χ2 values were 7.75-15.15, all P<0.05). The Hosmer-Lemeshow test indicated good model fit ( χ2=6.21, P>0.05). The combined predictive model demonstrated significantly better discrimination than individual factors, the area under the curve of ROC was 0.846 ( P<0.01). Conclusions:The incidence of treatment delay is relatively high among breast cancer-related lymphedema patients. Nursing staff should pay special attention to patients with a junior high school education or below, no regular arm circumference measurement, low LSMS-BCs scores, low BIPQ-BCRL scores, high PBHSD-C scores and low HLSCP scores, implement timely interventions to reduce treatment delay in lymphedema patients.
