Objective:To analyze the characteristics,high-risk factors,and maternal fetal outcomes of intrahe-patic cholestasis of pregnancy(ICP)in twin pregnancies,and provide a basis for clinical intervention.Methods:A retrospective analysis was conducted on 791 cases twin pregnant women who gave birth ≥24 weeks of gestation at Changsha Maternal and Child Health Hospital affiliated to Hunan Normal University from January 1,2021 to No-vember 30,2024.According to whether the pregnant women were complicated with ICP,all included twin pregnant women were divided into two groups,with 732 cases in the non ICP group and 59 cases in the ICP group.The differences in clinical characteristics,high-risk factors,and maternal fetal outcomes between two groups were compared,and Logistic regression analysis was used to identify the influencing factors of ICP in twin pregnancies.Results:①Among the women with twin live births who gave birth at ≥24 weeks of gestation,the incidence of ICP was 7.46％(59/791),and the proportion of mildly elevated total bile acid(TBA)was 83.05％(49/59);The inci-dence of ICP was highest at 34-36+6 weeks of pregnancy,accounting for 52.54％(31/59),and the incidence be-fore full-term was 77.97％(46/59);The treatment rate of TBA lowering drugs was 37.29％(22/59),and the inef-fective rate of drug treatment was 68.18％(15/22).②Univariate analysis found that the proportion of preeclamp-sia(PE)and previous cesarean section history in the ICP group was higher than that in the non ICP group,and the difference was statistically significant(P＜0.05).③ Logistic regression analysis suggests that,PE(OR 3.104,95％CI 1.763-5.466)and a history of previous cesarean section(OR 2.252,95％CI 1.039-4.878)were an inde-pendent risk factor for ICP in twins(P＜0.05).④The gestational age at delivery and birth weight of newborns in the ICP group were lower than those in the non ICP group.The premature birth rate,cesarean section rate,and neonatal transfer rate were higher than those in the non ICP group,and the differences were statistically signifi-cant(P＜0.05).Conclusions:PE and previous cesarean section history are high-risk factors for the occurrence of ICP in twin pregnancies.A detailed understanding of past medical history and active prevention of PE are bene-ficial for preventing the occurrence of ICP in twin pregnancies.

Objective:To explore the efficacy and adverse reactions of CAG regimen combined with venetoclax,chidamide,and azacitidine in the treatment of elderly patients with acute myeloid leukemia(AML).Methods:15 elderly AML patients aged ≥ 60 years old who were admitted to the Hematology Department of our hospital from May 2022 to October 2023 were treated with the CAG regimen combined with venetoclax,chidamide and azacitidine,and the efficacy,treatment-related adverse events,overall survival(OS)and event-free survival(EFS)were analyzed.Results:After one course of treatment,11 out of 15 patients achieved complete response(CR),3 patients achieved CR with incomplete hematologic recovery(CRi),and 1 patient died due to prior infection before efficacy evaluation,and the overall response rate(ORR)was 93.3％(14/15).The median follow-up time was 131(19-275)days,with median OS and EFS both remaining unreached.Next-generation sequencing(NGS)analysis showed that among the 15 patients,13 were detected with gene mutations,and there were 7 genes with mutation frequencies of more than 10％,including ASXL1(4 cases),RUNX1(4 cases),BCOR(3 cases),DNMT3A(3 cases),STAG2(2 cases),IDH1/2(2 cases),and TET(2 cases).Among the 13 patients with detectable mutations,12 patients achieved composite response(CR+CRi).The average recovery time of white blood cell count was 14.6 days after chemotherapy,and the average recovery time of platelets was 7.7 days after chemotherapy.The main adverse event was myelosuppression,with 10 patients accompanied by infection.Except for 1 patient who died due to septic shock during chemotherapy,no patients experienced serious complications such as heart,liver,or kidney damage during the treatment process.Conclusion:The CACAG+V regimen,which combines the CAG regimen with venetoclax,chidamide,and azacitidine,can be applied in the treatment of elderly AML patients,demonstrating good safety and induction remission rate.

Natural products are important sources for the discovery of anti-tumor drugs. Evodiamine is the main alkaloid component of the traditional Chinese herb Wu-Chu-Yu, and it has weak antitumor activity. In recent years, a number of highly active antitumor candidates have been discovered with a significant progress. This article reviews the research progress of evodiamine-based antitumor drug design strategies, in order to provide reference for the development of new drugs with natural products as leads.

Objective:To investigate the efficacy and safety of Venetoclax combined with CACAG regimen in treatment of patients with refractory/relapse acute myeloid leukemia(R/R AML).Methods:The study was a singlecenter prospective clinical trial.The enrolled patients met the criteria for R/R AML.Treatment included Azacidine(75mg/m2,d1-7),Ara-C(75-100 mg/m2,q12h,d1-5),Aclacinomycin(20 mg d1,d3,d5),Chidamide(30 mg d1,d4),Venetoclax(100 mg d1,200 mg d2,400 mg d3-d14,in combination with Triazole Drug,reduced to 100 mg/d),and granulocyte colony-stimulating factor(300 μg/d until neutrophil recovery).The primary endpoint of observation was overall response rate after 1 course of treatment.Results:A total of 19 patients were enrolled from January 2022 to April 2023.After 1 course of treatmen,the overall response rate was 81.3％(13/16),the CR rate was 68.8％(11/16),and the PR was 12.5％(2/16).Among the 11 patients who got CR/CRi,8 cases achieved CRm(minimal residual disease negative CR)and 3 cases did not.As of March 27,2023,the median follow-up time was 111(19-406)days.The six-month overall survival and progression-free survival rates were both 55.7％,the 1-year overall survival and progression-free survival rates were 46.4％and 47.7％,respectively.In addition,compared with the non-CRm group,CRm patients had a better PFS(377 days vsi11 days,P=0.046).Treatment-related adverse events were mainly 3-4 degrees of bone marrow suppression,complicated by various degrees of infection(n=12),hypokalemia(n=12)and hypocalcemia(n=10)and elevated liver enzymes(n=8),of which 3/4 degrees accounted for 47.4％(9/19).Conclusion:The Venetoclax combined with CACAG regimen is an effective salvage therapy for patients with R/R AML,with high remission rate and safety profile.

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 analyze the clinical characteristics of children with Burkitt lymphoma (BL) and to summarize the mid-term efficacy of China Net Childhood Lymphoma-mature B-cell lymphoma 2017 (CNCL-B-NHL-2017) regimen. Methods: Clinical features of 436 BL patients who were ≤18 years old and treated with the CNCL-B-NHL-2017 regimen from May 2017 to April 2021 were analyzed retrospectively. Clinical characteristics of patients at disease onset were analyzed and the therapeutic effects of patients with different clinical stages and risk groups were compared. Survival analysis was performed by Kaplan-Meier method, and Cox regression was used to identify the prognostic factors. Results: Among 436 patients, there were 368 (84.4%) males and 68 (15.6%) females, the age of disease onset was 6.0 (4.0, 9.0) years old. According to the St. Jude staging system, there were 4 patients (0.9%) with stage Ⅰ, 30 patients (6.9%) with stage Ⅱ, 217 patients (49.8%) with stage Ⅲ, and 185 patients (42.4%) with stage Ⅳ. All patients were stratified into following risk groups: group A (n=1, 0.2%), group B1 (n=46, 10.6%), group B2 (n=19, 4.4%), group C1 (n=285, 65.4%), group C2 (n=85, 19.5%). Sixty-three patients (14.4%) were treated with chemotherapy only and 373 patients (85.6%) were treated with chemotherapy combined with rituximab. Twenty-one patients (4.8%) suffered from progressive disease, 3 patients (0.7%) relapsed, and 13 patients (3.0%) died of treatment-related complications. The follow-up time of all patients was 24.0 (13.0, 35.0) months, the 2-year event free survival (EFS) rate of all patients was (90.9±1.4) %. The 2-year EFS rates of group A, B1, B2, C1 and C2 were 100.0%, 100.0%, (94.7±5.1) %, (90.7±1.7) % and (85.9±4.0) %, respectively. The 2-year EFS rates was higher in group A, B1, and B2 than those in group C1 (χ²=4.16, P=0.041) and group C2 (χ²=7.21, P=0.007). The 2-year EFS rates of the patients treated with chemotherapy alone and those treated with chemotherapy combined with rituximab were (79.3±5.1)% and (92.9±1.4)% (χ²=14.23, P<0.001) respectively. Multivariate analysis showed that stage Ⅳ (including leukemia stage), serum lactate dehydrogenase (LDH)>4-fold normal value, and with residual tumor in the mid-term evaluation were risk factors for poor prognosis (HR=1.38,1.23,8.52,95%CI 1.05-1.82,1.05-1.43,3.96-18.30). Conclusions: The CNCL-B-NHL-2017 regimen show significant effect in the treatment of pediatric BL. The combination of rituximab improve the efficacy further.

OBJECTIVE: To investigate the clinical characteristics, treatment, and prognosis of seizures in children with acute lymphoblastic leukemia (ALL) during chemotherapy. METHODS: Children with ALL with seizures during chemotherapy admitted to the Department of Pediatrics, Peking University People's Hospital from January 2010 to March 2022 were retrospectively analyzed. Clinical data including the incidence of seizure, time at seizure onset, causes, management, and prognosis were collected retrospectively. RESULTS: A total of 932 children with ALL were admitted during the study period, of whom, 75 (8%) were complicated with seizures during the period of chemotherapy. There were 40 males and 35 females, with a median age of 7.5 (1-17) years, and 43 cases (57.3%) occurred within the first 2 months of chemotherapy. The underlying diseases were reversible posterior encephalopathy syndrome (n=15), cerebral hemorrhage (n=10, one of whom was complicated with venous sinus thrombosis), intrathecal or systemic methotrexate administration (n=11), brain abscess (n=7, fungal infection in 3 cases, and bacterial in 4), viral encephalitis (n=2), febrile seizure (n=7), hyponatremia (n=7), hypocalcemia (n=2), and unknown cause (n=14). Sixty-four children underwent neuroimaging examination after seizure occurrence, of whom 37 (57.8%) were abnormal. The electroencephalograhpy (EEG) was performed in 44 cases and was abnormal in 24 (54.4%). Fifty-five patients remained in long-term remission with regular chemotherapy, 8 patients received hematopoietic stem cell transplantation, 9 died and 3 lost to follow-up. Symptomatic epilepsy was diagnosed in 18 cases (24%), and was well controlled in 16 with over 1 year of seizure-free. Whereas 2 cases were refractory to anti-seizure medications. CONCLUSION Seizures are relatively common in children with ALL, most commonly due to reversible posterior encephalopathy syndrome, methotrexate-related neurotoxicity, and cerebral hemorrhage. Seizures occurred within 2 months of chemotherapy in most cases. Neuroimaging and EEG should be performed as soon as possible after the first seizure onset to identify the etiology and to improve the treatment regimen. Some cases developed symptomatic epilepsy, with a satisfactory outcome of seizure remission mostly after concurrent antiseizure medication therapy.

OBJECTIVE: To explore the relationship between drug treatment and outcomes in patients with late-onset severe pneumonia (LOSP) after allogeneic stem cell transplantation (allo-SCT). METHODS: We retrospectively analyzed the effects of the initiation time of treatment drugs, especially antiviral drugs and glucocorticoids on the clinical outcomes in 82 patients between January 2016 and August 2021 who developed LOSP after allo-SCT in Peking University People's Hospital. Univariate analysis was performed by Mann-Whitney U test and χ² test, and multivariate analysis was performed by Logistic regression. When multiple groups (n>2) were involved in the χ² test, Bonferroni correction was used for the level of significance test. RESULTS: Of all 82 patients in this study, the median onset time of LOSP was 220 d (93-813 d) after transplantation, and the 60-day survival rate was 58.5% (48/82). The median improvement time of the survival patients was 18 d (7-44 d), while the median death time of the died patients was 22 d (2-53 d). Multivariate analysis showed that the initiation time of antiviral drugs from the onset of LOSP (< 10 d vs. ≥10 d, P=0.012), and the initiation time of glucocorticoids from antiviral drugs (< 10 d vs. ≥10 d, P=0.027) were the factors affecting the final outcome of the patients with LOSP at the end of 60 d. According to the above results, LOSP patients were divided into four subgroups: group A (antiviral drugs < 10 d, glucocorticoids ≥10 d), group B (antiviral drugs < 10 d, glucocorticoids < 10 d), group C (antiviral drugs ≥10 d, glucocorticoids ≥10 d) and group D (antiviral drugs ≥10 d, glucocorticoids < 10 d), the 60-day survival rates were 91.7%, 56.8%, 50.0% and 21.4%, respectively. CONCLUSION Our study demonstrated that in patients who developed LOSP after allo-SCT, the initiation time of antiviral drugs and glucocorticoids were associated with the prognosis of LOSP, and the survival rate was highest in patients who received antiviral drugs early and glucocorticoids later. It suggested that for patients with LOSP of unknown etiology should be highly suspicious of the possibility of a secondary hyperimmune response to viral infection.
