ObjectiveTo construct and validate a clinical prediction model for Qi deficiency and blood stasis syndrome in chronic heart failure （CHF），aiming to assist clinical diagnosis and provide tools and methods for individualized treatment of CHF. MethodsThe clinical data of patients with chronic heart failure treated at Dongzhimen Hospital of Beijing University of Chinese Medicine from January 2022 to January 2024 were retrospectively collected. The patients were randomly divided into a training group and a validation group with a ratio of 7∶3. First， the least absolute shrinkage and selection operator （LASSO） regression analysis was used to preliminarily screen the predictive factors affecting the diagnosis of Qi deficiency and blood stasis syndrome in CHF. Subsequently， the Logistic regression method was applied to conduct a more in-depth and detailed analysis of these factors. Variables with P<0.05 in the results of the multi-factor Logistic regression were carefully selected and included. Based on the regression coefficients obtained from this analysis， a model was constructed， and a nomogram was accurately drawn. Using R software，the receiver operating characteristic （ROC） curve，calibration curve，and decision curve analysis （DCA） were precisely drawn. These analyses were used to comprehensively evaluate the model from three crucial aspects： discrimination，calibration，and clinical applicability. Additionally， the accuracy，specificity，sensitivity，positive predictive value，and negative predictive value of the model were meticulously calculated to conduct a more all-round and comprehensive assessment. ResultsIn total， 168 cases were successfully obtained in the training group， and 71 cases were included in the validation group. After a thorough comparison， it was found that there were no statistically significant differences in the baseline data between the two groups. After being rigorously screened by the LASSO-multivariate logistic regression method， dark red tongue，smoking history，cardiac troponin I，and N-terminal pro-B-type natriuretic peptide （NT-ProBNP） were identified as the influencing factors for diagnosing patients with the Qi deficiency and blood stasis syndrome in CHF. The constructed model demonstrated an area under the curve （AUC） of 0.812 in the training group and 0.719 in the validation group. The calibration curve showed that the predicted curve of the model was close to the actual observed curve. DCA indicated that the model could provide substantial clinical benefits for patients at the decision thresholds ranging from 0.2 to 0.9. ConclusionThe clinical prediction model for Qi deficiency and blood stasis syndrome in chronic heart failure constructed in this study shows good performance. It has certain application value in clinical practice， which may contribute to the improvement of the diagnosis and treatment of CHF patients with this syndrome.

Objective To evaluate the clinical efficacy of oral use of Jiawei Puji Xiaodu Granules(mainly composed of Lonicerae Japonicae Flos,Forsythiae Fructus,Taraxaci Herba,Violae Herba,Schizonepetae Herba,Arctii Fructus,Gleditsiae Spina,Paeoniae Radix Rubra,Moutan Cortex,and Phragmitis Rhizoma)combined with external application of Xiaozhong Sanjie Ointment(mainly composed of Scutellariae Radix,Coptidis Rhizoma,Phellodendri Chinensis Cortex,and Gleditsiae Spina,etc.)in the treatment of acute tonsillitis in children,and to observe their effects on the immune function and related inflammatory indexes of the patients.Methods A total of 116 children with acute tonsillitis of heat stagnation in the lung and stomach type were randomly divided into the control group and the observation group,with 58 cases in each group.The control group was treated with Cefixime Dispersible Tablets,while the observation group was treated with Jiawei Puji Xiaodu Granules for oral use and Xiaozhong Sanjie Ointment for external application.Both groups were treated for 14 days and then were followed-up for a period of 6 months.The changes of traditional Chinese medicine(TCM)syndrome scores,white blood cell(WBC)count,T lymphocyte subset CD3+,CD4+,CD8+ and CD4+/CD8+ levels,and serum levels of tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β),interleukin 6(IL-6)and C-reactive protein(CRP)in the two groups were observed before and after the treatment.Moreover,the clinical efficacy and time for the disappearance of clinical symptoms were compared between the two groups,and the occurrence of adverse reactions and the recurrence of tonsillitis in the two groups were monitored at the same time.Results(1)During the trial,there were 8 cases falling off in the control group but none case falling off in the observation group,and eventually 50 cases in the control group and 58 cases in the observation group completed the full course of treatment.(2)After 14 days of treatment,the total effective rate of the observation group was 98.28%(57/58),while that of the control group was 90.00%(45/50).The intergroup(tested by rank sum test)showed that the clinical efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(3)After treatment,the time for the disappearance of sore throat,time for the disappearance of purulent spots,time for subsiding fever and time for the tonsils recovering to normal in the observation group were all significantly shorter than those in the control group(P＜0.05).(4)After treatment,the scores of primary and secondary symptoms and the overall symptom scores in the two groups were significantly lower than those before treatment(P＜0.05),and the reduction of the scores in the observation group was significantly superior to that in the control group(P＜0.05).(5)After treatment,the levels of T lymphocyte subset CD3+,CD4+ and CD4+/CD8+ in the two groups were significantly higher(P＜0.05)while the level of CD8 + was significantly lower(P＜0.05)than those before treatment,and the increase in the levels of CD3+,CD4+ and CD4+/CD8+ and the reduction of the CD8+ level of the observation group were significantly superior to those of the control group(P＜0.05).(6)After treatment,the levels of WBC,TNF-α,IL-1β,IL-6 and CRP in the two groups were significantly lower than those before treatment(P＜0.05),and the reduction in the observation group was significantly superior to that in the control group(P＜0.05).(7)During the treatment period,no skin allergy,nausea,vomiting or other gastrointestinal adverse reactions occurred in the two groups,which showed a high degree of safety.(8)The 6-month follow-up showed that the recurrence rate of tonsillitis in the observation group was 5.17%(3/58),which was significantly lower than that of 24.00%(12/50)in the control group,and the difference was statistically significant(χ2 = 8.330,P＜0.05).Conclusion The efficacy of Jiawei Puji Xiaodu Granules combined with Xiaozhong Sanjie Ointment exert notable curative effect for children with acute tonsillitis of heat stagnation in the lung and stomach type.The combined therapy can significantly shorten the duration of the disease,improve the clinical symptoms of the children and effectively reduce the recurrence rate of tonsillitis.The therapeutic mechanism may be related to the enhancement of the immune function and the inhibition of inflammatory response.

The clinical research in the field of extracorporeal life support (ECLS) in 2023 has focused on the efficacy of veno-arterial extracorporeal membrane oxygenation (ECMO) in patients with infarct-related cardiogenic shock. Additionally, the research also explored the efficacy of prone positioning during veno-venous ECMO, transfusion strategies, and the impact of obesity on outcomes. Awake veno-venous ECMO has shown novel therapeutic potential, but its optimal practice methods and management strategies remain to be determined. In in-hospital cardiac arrest patients, extracorporeal cardiopulmonary resuscitation has demonstrated higher survival rates and better neurological recovery compared to conventional cardiopulmonary resuscitation. The effectiveness of extracorporeal carbon dioxide removal varies among patients with different types of respiratory failure. Future research should focus on optimizing the application strategies and process management of ECLS technologies, investigating personalized therapy, and studying how to improve long-term rehabilitation and quality of life for survivors.

Cardio-oncology is an emerging cross-discipline， which has received extensive attention and rapid development at home and abroad in recent years， while the construction of related disciplines in the field of traditional Chinese medicine （TCM） is still in its initial stage. By sorting out the construction of oncology and cardiology related disciplines at home and abroad at this stage， and clarifying the significance and main research contents of the discipline， it is proposed that the construction of TCM related disciplines should be oriented to the four main aspects， including clinical practice， scientific research， talent training and promotion of cultural characteristics. Therefore， actively carrying out multidisciplinary crossing， cultivating related professional talent team， and forming TCM diagnosis and treatment guidelines or consensus to support clinical practice is the essential foundation for the construction of TCM cardio-oncology discipline. Meanwhile， fully exploring the characteristics and advantages of TCM is the key to the construction process of the discipline， such as writing and summarising and analysing relevant high-quality clinical case reports of TCM for evidence-based optimisation， as well as widely applying the concept of "treating disease before it arises" of TCM characteristics to the clinical prevention and treatment of the relevant diseases and scientific research， etc.， so as to comprehensively guarantee the development of the discipline of TCM cardio-oncology.

Emphasizing symptom efficacy is an important manifestation of the personalized diagnosis and treatment of traditional Chinese medicine （TCM）. However， in current clinical practice of TCM， there are challenges such as diverse symptom expressions， difficulty in standardization， inconsistent evaluation standards for symptom efficacy， lack of universal quantitative methods， and complexity in collecting complete and accurate symptom information. These issues hinder the full and effective utilization of symptom information. Addressing the current research status and existing problems of symptom terminology standardization， quantification and grading of symptom efficacy， and collection of symptom information， this paper proposes methodological strategies for effectively recording and utilizing TCM symptom efficacy information in the era of big data. These strategies include collecting TCM symptom information based on patient reporting， standardizing the evaluation of TCM symptom efficacy from measurement scales and evaluation dimensions， integrating TCM symptom efficacy evaluation into clinical diagnosis and treatment processes， and utilizing artificial intelligence technology to acquire and process TCM symptom efficacy information. TCM symptom efficacy evaluation strategies based on patient perspectives and artificial intelligence technology will help fully explore the value of data elements， promote the objective demonstration of the specific efficacy of TCM， and facilitate the discovery of effective patterns.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Critical care medicine is a discipline dedicated to the diagnosis and treatment of severe illnesses,demanding extensive knowledge,advanced skills,and exceptional teamwork and communication abilities.However,the complexity and dynamic nature of critically ill patients often render traditional face-to-face teaching methods insufficient.Emerging educational approaches like virtual reality(VR)and augmented reality(AR)offer simulated environments,but lack the depth of interaction with the real world,constraining the educational outcomes.Mixed reality(MR),which integrates elements of both VR and AR,provides an immersive and highly interactive learning experience by seamlessly bridging the virtual and real worlds.Although MR has begun to establish itself in medical education,its application in critical care medicine remains in its early stages.This article aims to elucidate the characteristics and evolution of MR,alongside its potential value and applications in critical care medical education.

Investigating the species/biovars,distribution patterns,and genetic correlations of Brucella from sheep in north-west China is critical to reveal the population and epidemiological characteristics of the Brucella melitensis.In this study,con-ventional identification and AMOS-PCR were used to determine the species/biovars of Brucella isolated from 13 regions in northwest China.MLST and MLVA-16 genotyping methods were used to analyze the genetic characteristics of the strains.Con-ventional identification and AMOS-PCR detection revealed that 59 Brucella melitensis were isolated in this study,in-cluding 22 strains from Inner Mongolia,17 strains from Xin-jiang,13 strains from Gansu,and 7 strains from Qinghai,of which 58 strains were B.melitensis biovar 3,and one strain was B.melitensis biovar 1.MLST analysis indicated that 90％(53/59)of B.melitensis were of ST8 sequence type,the dominant epidemic population.The MLVA-11 survey demonstrated that 59 B.melitensis strains clustered into six MLVA-11 genotypes,and 87％of the strains were of MLVA-11 genotype 116.Therefore,the predominant strains in the northwest region were from the Eastern Mediterranean lineage.MLVA-16 divided 59 strains of B.melitensis into 40 gen-otypes,eight of which were shared genotypes.Each genotype was composed of two to seven strains from the same region,thereby indicating that the cases of each shared genotype were outbreaks from a common source of infection.All shared MLVA-16 genotypes comprised strains from the same province,thus indicating apparent regional clustering characteristics of strains in each province.In a genetic comparison between populations and isolated strains from the spleens of sheep,multiple identical MLVA-16 genotypes were found to be composed of strains from different hosts.These findings indicated a transmission path-way from sheep/goats to humans.B.melitensis biovar 3 was the main pathogen causing animal brucellosis in the northwest re-gion,and infected sheep were the main brucellosis infection source in the regional population.The ST8 strains were the domi-nant epidemic population,and the MLVA genotype of strains in each region showed clear regional clustering characteristics.

Objective:To analyze the effect of recombinant human thrombopoietin(rhTPO)on platelet(PLT)reconstitution after autologous peripheral blood stem cell transplantation(APBSCT)in patients with multiple myeloma(MM).Methods:The clinical data of 147 MM patients who were diagnosed in the First Affiliated Hospital of Soochow University and received APBSCT as the first-line therapy were retrospectively analyzed.According to whether rhTPO was used during APBSCT,the patients were divided into rhTPO group(80 cases)and control group(67 cases).The time of PLT engraftment,blood product infusion requirements,the proportion of patients with PLT recovery to ≥ 50 × 109/L and ≥ 100 × 109/L at+14 days and+100 days after transplantation,and adverse reactions including the incidence of bleeding were compared between the two groups.Results:There were no significant differences between the two groups in sex,age,M protein type,PLT count at the initial diagnosis,median duration of induction therapy before APBSCT,and number of CD34+cells reinfused(all P＞0.05).The median time of PLT engraftment in the rhTPO group was 10(6-14)days,which was shorter than 11(8-23)days in the control group(P＜0.001).The median PLT transfusion requirement in the rhTPO group during APBSCT was 15(0-50)U,which was less than 20(0-80)U in the control group(P=0.001).At+14 days after transplantation,the proportions of patients with PLT 2 50 × 109/L in the rhTPO group and the control group were 66.3％and 52.2％,while the proportions of patients with PLT ≥ 100 × 109/L were 23.8％and 11.9％,respectively,with no significant differences(all P＞0.05).At+100 days after transplantation,the proportion of patients with PLT ≥ 50 × 109/L in rhTPO group and control group was 96.3％and 89.6％,respectively(P＞0.05),but the proportion of patients with PLT ≥ 100 × 109/L in rhTPO group was higher than that in control group(75.0％vs 55.2％,P=0.012).There was no difference in the overall incidence of bleeding events in different locations during period of low PLT level of patients between the two groups.In rhTPO group,the rhTPO administration was well tolerated,and the incidences of abnormal liver and kidney function and infection were similar to those in the control group.Conclusion:When MM patients undergo first-line APBSCT,subcutaneous injection of rhTPO can shorten the time of platelet engraftment,reduce the transfusion volume of blood products,and be well tolerated,moreover,more patients have achieve a high level of PLT recovery after transplantation,which is very important for ensuring the safety of APBSCT and maintenance therapy.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Sepsis-induced cell lysis and necrosis lead to the passive release of mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) into circulation. These DNAs bind to pattern recognition receptor (PRR), triggering excessive inflammatory cytokines production and increasing mortality. Three prime repair exonuclease 1 (TREX1) is a 3' to 5' exonuclease that rapidly degrades single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA) by cleaving phosphodiester bonds. This process can prevent the accumulation of damaged DNA in the cytoplasm, thereby averting abnormal inflammation and pathological immune responses. TREX1 thus plays a significant role in regulating DNA-related damage caused by sepsis. However, the role and underlying mechanisms of TREX1 in sepsis have not been thoroughly discussed. This review aims to elucidate the structure and function of TREX1 and its mediated immune regulatory mechanisms, with the hope of clarifying the potential role of TREX1 in the field of sepsis.
