OBJECTIVES: To construct a Z-score regression model for coronary artery diameter based on echocardiographic data from children in Sichuan Province and to establish a Z-score calculation formula. METHODS: A total of 744 healthy children who underwent physical examinations at Sichuan Provincial People's Hospital from January 2020 to December 2022 were selected as the modeling group, while 251 children diagnosed with Kawasaki disease at the same hospital from January 2018 to December 2022 were selected as the validation group. Pearson correlation analysis was conducted to analyze the relationships between coronary artery diameter values and age, height, weight, and body surface area. A regression model was constructed using function transformation to identify the optimal regression model and establish the Z-score calculation formula, which was then validated. RESULTS: The Pearson correlation analysis showed that the correlation coefficients for the diameters of the left main coronary artery, left anterior descending artery, left circumflex artery, and right coronary artery with body surface area were 0.815, 0.793, 0.704, and 0.802, respectively (P<0.05). Among the constructed regression models, the power function regression model demonstrated the best performance and was therefore chosen as the optimal model for establishing the Z-score calculation formula. Based on this Z-score calculation formula, the detection rate of coronary artery lesions was found to be 21.5% (54/251), which was higher than the detection rate based on absolute values of coronary artery diameter. Notably, in the left anterior descending and left circumflex arteries, the detection rate of coronary artery lesions using this Z-score calculation formula was higher than that of previous classic Z-score calculation formulas. CONCLUSIONS The Z-score calculation formula established based on the power function regression model has a higher detection rate for coronary artery lesions, providing a strong reference for clinicians, particularly in assessing coronary artery lesions in children with Kawasaki disease.

OBJECTIVE: To describe survival trends and global patterns of esophageal cancer (EC) using survival data from population-based cancer registries. METHODS: We systematically searched PubMed, EMBASE, Web of Science, SEER, and SinoMed databases for articles published up to 31 December 2023. Eligible EC survival estimates were evaluated according to country or region, period, sex, age group, pathology, and disease stage. RESULTS: After 2010, Jordan exhibited the highest age-standardized 5-year relative survival rates (RSRs)/net survival rates (NSRs) at 41.1% between 2010 and 2014, while India had the lowest, at 4.1%. Survival rates generally improved with diagnostic age across most countries, with significant increases in South Korea and China, of 12.7% and 10.5% between 2000 and 2017, respectively. Survival was higher among women compared to men, ranging from 0.4%-10.9%. Survival rates for adenocarcinoma and squamous cell carcinoma were similar, differing by about 4%. In China, the highest age-standardized RSRs/NSRs was 33.4% between 2015 and 2017. Meanwhile, the lowest was 5.3%, in Qidong (Jiangsu province) between 1992-1996. CONCLUSION Global EC survival rates have improved significantly in recent decades, but substantial geographical, sex, and age disparities still exist. In Asia, squamous cell carcinoma demonstrated superior survival rates compared to adenocarcinoma, while the opposite trend was observed in Western countries. Future research should clarify the prognostic factors influencing EC survival and tailor prevention and screening strategies to the changing EC survival patterns.

This study employed ultrahigh-performance liquid chromatograph-hybrid quadrupole orbitrap high resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS) to detect the chemical constituents of traditional Chinese medicine in Sizi Dingchuan granules. Network pharmacology and molecular docking techniques were then utilized to predict the effects of Sizi Dingchuan granules on bronchial asthma, along with its target molecules and signaling pathways. UHPLC analysis identified 172 compounds, including 84 flavonoids, 38 organic acids and their derivatives, 22 phenylpropanoids, 16 organic oxygen compounds, 3 phenolic compounds, 2 terpenoids, 2 sugars and glycosides, and 5 other compounds. Typical compound fragmentation patterns were documented. Using network pharmacology methods, 117 compounds were ultimately selected for target prediction, establishing a “drug-component-target-disease” network, which revealed that quercetin, schisandrin A, baicalin, gomisin H, and baicalin exhibit multiple targets related to bronchial asthma, suggesting that they may be the active components responsible for the compound’s efficacy in treating this condition. Protein-protein interaction analysis identified core targets including TNF, IL-6, JAK2, STAT3, BCL2, CASP3, and EGFR, primarily clustered within the JAK-STAT signaling pathway. This suggests that the main components of Sizi Dingchuan granules may regulate the balance between Th17 and Treg cells, as well as Th1 and Th2 cell differentiation, by modulating the JAK-STAT signaling pathway, thereby exerting a positive therapeutic effect on bronchial asthma.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the predictive value of serum lipoprotein-associated phospho-lipase A2(Lp-PLA2)for long-term prognosis of elderly patients with stable coronary heart dis-ease(CHD).Methods A retrospective trial was conducted on 198 patients with stable CHD ad-mitted to our hospital from January 2016 to December 2018.All of them were followed up for 5 years,and divided into adverse cardiovascular event group(n=42)and control group(n=156)according to whether adverse cardiovascular events occurred during follow-up.Clinical features and Lp-PLA2 level were compared between the two groups.The predictive value of Lp-PLA2 for adverse cardiovascular events was analyzed in elderly patients with stable CHD within 5 years.Re-sults The adverse cardiovascular event group had significantly older age(74.95±7.02 vs 70.17±6.30 years,P=0.000),larger proportions of diabetes(54.76％vs 27.56％,P=0.001),of coronary artery stenosis ≥75％(69.05％vs 47.44％,P=0.013)and of left ventricular ejection fraction(LVEF)＜50％(50.00％vs 28.21％,P=0.008),and higher Lp-PLA2 level(478.38±187.54 U/L vs 308.17±126.73 U/L,P=0.000)when compared with the control group.The AUC value of age and Lp-PLA2 was 0.683(95％CI:0.590--0.776,P＜0.001)and 0.763(95％CI:0.677--0.848,P=0.763),respectively,in predicting the long-term prognosis in elderly patients with stable CHD.Multivariate logistic regression analysis showed that age,diabetes,coronary artery stenosis ≥75％,LVEF＜50％and Lp-PLA2 were independent influencing factors for adverse cardiovascular events within 5 years in elderly patients with stable CHD(P＜0.05,P＜0.01).Con-clusion Increased Lp-PLA2 level is associated with adverse cardiovascular events within 5 years in patients with stable CHD.

Objective:To investigate the impact of early blood glucose fluctuations after acute multiple injuries on post-traumatic stress disorder (PTSD).Methods:This study was a case-control study. From March 2022 to March 2023, patients with acute multiple injuries who were admitted to the ICU of the Affiliated Hospital of Xuzhou Medical University were selected. According to whether complicated with traumatic brain injury (TBI), the patients were divided into TBI group and non-TBI group. Early post-traumatic blood glucose fluctuations were observed, including stress-induced hyperglycemia (SIH), initial blood glucose value on admission, blood glucose extreme, short-term glycemic variability (GV) and other related indicators. The 72-hour glucose coefficient of variation (Glu-CV) was used to reflect short-term GV. After 1 month, the PTSD checklist for DSM-5 (PCL-5) was used to assess the patient's symptoms of PTSD. The patients were divided into PTSD group and non-PTSD group according to PCL-5 score ≥38. The differences in short-term glucose fluctuations in each groups were compared; the risk factors of PTSD were analyzed by logistic regression; the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of related indicators on the incidence of PTSD.Results:159 patients with acute multiple injuries were selected and defined as the TBI group ( n=94) and non-TBI group ( n=65). The incidence of PTSD, PCL-5 scale scores, the incidence of SIH and 72 h Glu-CV in the TBI group were significantly higher than the non-TBI group (all P<0.05). The incidence of SIH and 72 h Glu-CV in the PTSD group were significantly higher than the non-PTSD group (both P<0.05). Multivariate logistic regression analysis showed that 72 h Glu-CV ( OR=1.333, 95% CI: 1.028-1.727, P=0.030) was the independent risk factor for PTSD after acute multiple injuries, and the area under the ROC curve was 0.861 (95% CI: 0.789-0.933, P<0.001), the sensitivity was 62.9% and the specificity was 93.5%. Conclusion:Patients with acute multiple injuries with TBI are more likely to have early glucose fluctuations and develop PTSD, and increased short-term glucose variability is the independent risk factor for PTSD after acute multiple injuries.

Objective:To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

This study explored the generation site and regulation mechanism of reactive oxygen species(ROS) in the apoptosis of colorectal cancer cells induced by furanodienone(Fur). RKO cells were treated with 200 μmol·L~(-1) of Fur, and the changes in intracellular nicotinamide adenine dinucleotide phosphate oxidase(NOX) activity were detected by the NOX activity detection method. The control group, Fur group, diphenyleneiodonium(DPI) inhibitor group for general NOX, mitochondrial-targeted antioxidant(MitoTEMPO) group, Fur+DPI group, Fur+MitoTEMPO group, and H_2O_2 positive control group were set up. Intracellular ROS levels were detected by the ROS fluorescent staining method, and NOX1-NOX5 protein expressions were detected by Western blot. The NOX1-specific inhibitor ML171 and NOX4-specific inhibitor(GLX351322) were further introduced, and the cell activity was determined by cell counting kit-8(CCK-8) assay. The effects of ROS level change on the protein expressions of NOX4 and peroxiredoxin 1(PRDX1) were measured by Western blot. BAY11-7082, which is an inhibitor of the inhibitor of nuclear factor κB protein α(IκBα), was used to explore the effect of the expression of phosphorylated nuclear factor κB(p-NF-κB) in the nucleus after the Fur treatment on the NOX4 protein level. The lentiviral plasmid and empty plasmid for PRDX1 gene silencing were constructed to transfect RKO cells, and stably transfected strains were screened. The impact of PRDX1 gene knockout on Fur-induced apoptosis was further analyzed using the flow cytometry assay. The findings demonstrate a considerable increase in mitochondrial ROS level in response to Fur treatment, with an increase in intracellular NOX activity. However, the mitochondrial ROS level is significantly reduced in the Fur+DPI group. The results from Western blot and CCK-8 analysis suggest that intracellular NOX1 and NOX4 protein expressions are elevated by Fur treatment, and GLX351322 effectively reverses the pro-apoptotic effect of Fur, while ML171 has a minimal impact on apoptosis rate. Meanwhile, Fur significantly boosts the level of p-NF-κB in the nucleus, whereas the protein levels of p-NF-κB and NOX4 are reduced after the BAY treatment. The regulation of Fur on NOX4 and PRDX1 protein expressions is negatively correlated. In the stably transfected cell strain with PRDX1 gene knockout, the apoptosis rate is considerably higher than that of the negative control group after Fur treatment. The above results indicate that Fur can induce the apoptosis of colorectal cancer cells by promoting the signal transduction of NF-κB in the nucleus and increasing the generation of mitochondrial ROS derived from NOX4 to inhibit the PRDX1 protein expression.

Xanthine oxidoreductase (XOR), the key enzyme catalyzing purine to produce uric acid, including two subtypes, xanthine dehydrogenase (XDH) and xanthine oxidase (XO), respectively, in vivo. Usually, XDH and XO can transform to each other. In this study, based on the principle that the subtype XO or XDH uses different electron acceptors, the methods for the measuring the activities of bovine milk XOR (pure enzyme) and its subtypes were established. The optimal concentrations of substrate xanthine (50 μmol·L^-1) and electron acceptor NAD⁺ (50 μmol·L^-1), pH value (7.80) were investigated. The ranges of the XOR, XO, XDH activity which could be determined were 0.97-17.5 U·L^-1, 1-9 U·L^-1, and 66-1 191 mU·L^-1, respectively. Furthermore, the methods for determining the activities of XOR and its subtypes in mouse liver were established. The preparation of liver samples, the optimal concentrations of xanthine (100 μmol·L^-1) and NAD⁺ (100 μmol·L^-1) were researched. And the activity ranges of XOR, XO and XDH in mouse liver which could be determined were 0.67-3.98, 0.19-1.08, and 0.52-3.55 U·gprot^-1, respectively. With the methods above, the effects of classic XOR inhibitor allopurinal (Allo) on XOR, XO and XDH from both milk and mouse liver were determined. All animal experiments have been approved by the Animal Experimental Center, Institute of Materia Medica, Chinese Academy of Medical Science and Peking Union Medical College (00003346). This study established new methods for the determination of XOR and its subtypes activity in pure enzyme system and in mouse liver, respectively, which were accurate and convenient. It laid the experimental foundation for exploring the different pathophysiological effects of XOR in the body and developing new XOR inhibitors.
