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 effect of the HtrA serine peptidase 3(HTRA3)gene on choroidal neovascu-larization(CNV)and M2 macrophage polarization.Methods Fasting venous blood was collected from 30 patients with wet age-related macular degeneration(wAMD group)and 30 healthy subjects(normal group).The serum HTRA3 messen-ger ribonucleic acid(mRNA)level was detected by quantitative reverse transcription polymerase chain reaction(qRT-PCR).RF/6A cells were randomly divided into the control group,NC-sh group and HTRA3-sh group.Lentiviral vectors of NC-shRNA and HTRA3-shRNA were transfected into RF/6A cells in the NC-sh group and HTRA3-sh group by Lipo-fectamine2000.HTRA3 transfection was detected by qRT-PCR and Western blot.Then,the RF/6A cells were randomly di-vided into the N group,H group,H+NC-sh group and H+HTRA3-sh group.After cell transfection,RF/6A cells in the N group were cultured in a RPMI 1640 complete medium at a normoxia state,and cells in other groups were cultured in a RP-MI 1640 medium with 200 mmol·L-1 CoCl2 at a hypoxia state.Tubule formation was measured by Matrigel.The C57BL/6J mice were divided into the control group,CNV group,CNV+NC-sh group and CNV+HTRA3-sh group,with 12 mice in each group.Mice in the control group were unmodeled mice,and mice in the other groups were laser-induced CNV model mice.NC-shRNA and HTRA3-shRNA lentiviral vectors with a titer of 1 × 1011 TU·mL-1 were administered to mice in the CNV+NC-sh group and CNV+HTRA3-sh group via intravitreal injection.Mice in the control group and CNV group were in-jected with phosphate buffered saline.After 7 days of treatment,the mice were examined by fundus fluorescein angiogra-phy,and the eyeballs received hematoxylin & eosin staining.The mRNA levels of HTRA3,chitinase-like protein 3(Ym-1),arginase 1(Arg-1),inducible nitric oxide synthase(iNOS),cyclooxygenase-2(COX-2)and vascular endothelial growth factor(VEGF)in RF/6A cells or choroidal tissues were detected by qRT-PCR.The protein expression levels of HTRA3,VEGF and nuclear factor kappa B(NF-κB)p65 in RF/6A cells or choroidal tissues were detected by Western blot.Re-sults Compared with the normal group,serum HTRA3 mRNA level of patients in the wAMD group increased(t=11.804,P＜0.001).Compared with the control group and NC-sh group,the expressions of HTRA3 mRNA and protein in RF/6A cells in the HTRA3-sh group decreased(all P＜0.05).Compared with the N group,the number of closed lumen and the mRNA and protein expressions of HTRA3 and VEGF in RF/6A cells in the H group increased(all P＜0.05).Compared with the H+NC-sh group,the number of closed lumen and the mRNA and protein expressions of HTRA3 and VEGF decreased in RF/6A cells in the H+HTRA3-sh group(all P＜0.05).Compared with the control group,the mRNA and protein expression levels of HTRA3 increased,the relative fluorescence intensity of CNV increased,the mRNA levels of Ym-1 and Arg-1 in-creased,the iNOS and COX-2 mRNA levels decreased,and the NF-κB p65 protein expression level increased in mice of the CNV group(all P＜0.05).Compared with the CNV+NC-sh group,the mRNA and protein expression levels of HTRA3 de-creased,the relative fluorescence intensity of CNV decreased,the mRNA levels of Ym-1 and Arg-1 decreased,the mRNA levels of iNOS and COX-2 increased,and the NF-κB p65 protein expression level decreased in mice of the CNV+HTRA3-sh group(all P＜0.05).Conclusion Down-regulation of HTRA3 can inhibit the formation of CNV and the polarization of M2 macrophages.HTRA3 may be an important potential target for the prevention and treatment of wAMD.

Objective To analyze the clinical characteristics of high energy metabolism in lung cancer patients and its correlation with body composition,nutritional status,and quality of life,and to develop a corresponding risk prediction model.Methods Retrospectively analyzed 132 primary lung cancer patients admitted to the First Hospital of Shanxi Medical University from January 2022 to May 2023,and categorized into high(n=94)and low energy metabolism group(n=38)based on their metabolic status.Differences in clinical data,body composition,Patient Generated Subjective Global Assessment(PG-SGA)scores,and European Organization for Research and treatment of Cancer(EORTC)Quality of Life Questionnaire-Core 30(QLQ-C30)scores were compared between the two groups.Logistic regression was used to identify the risk factors for high energy metabolism in lung cancer patients,and a risk prediction model was established accordingly;the Hosmer-Lemeshow test was used to assess the model fit,and the ROC curve was used to test the predictive efficacy of the model.Results Of the 132 patients with primary lung cancer,94(71.2%)exhibited high energy metabolism.Compared with low energy metabolism group,patients in high-energy metabolism group had a smoking index of 400 or higher,advanced disease staging of stage Ⅲ or Ⅳ,and higher levels of IL-6 level,low adiposity index,low skeletal muscle index,and malnutrition(P<0.05),and lower levels of total protein,albumin,hemoglobin level,and prognostic nutritional index(PNI)(P<0.05).There was no significant difference in age,gender,height,weight,BMI and disease type between the two groups(P>0.05).Logistic regression analysis showed that smoking index≥400,advanced disease stage,IL-6≥3.775 ng/L,and PNI<46.43 were independent risk factors for high energy metabolism in lung cancer patients.The AUC of the ROC curve for the established prediction model of high energy metabolism in lung cancer patients was 0.834(95%CI 0.763-0.904).Conclusion The high energy metabolic risk prediction model of lung cancer patients established in this study has good fit and prediction efficiency.

Objective:To investigate the timing and features of fine-needle aspiration biopsy (FNAB) guided by ultrasound for Bethesda Ⅲ thyroid nodules and to further optimize the puncture scheme.Methods:A retrospective analysis was conducted on data from patients who underwent rFNAB for Bethesda Ⅲ thyroid nodules at the China-japan Union Hospital of Jilin University Thyroid Surgery Department from Dec. 2020 to Dec. 2022. The study included 71 cases (73 nodules), consisting of 57 females and 14 males, with an average age of (45.7±10.4) years. Patients were grouped based on rFNAB results: Bethesda Ⅱ as the benign group ( n=21), Bethesda Ⅴ/Ⅵ as the malignant group ( n=39), and the remaining cases categorized as the indeterminate group ( n=13). Data on rFNAB results, puncture interval time, postoperative pathology, ultrasound features, and FNAB characteristics were recorded. Descriptive statistics were used for categorical data, presented as percentages and numbers, while continuous data were presented as mean ± standard deviation ( ± s). The χ2 test or Fisher's exact test was applied for analysis. Results:In this study, rFNAB was performed on 73 Bethesda Ⅲ thyroid nodules. The results showed that 60 nodules (82.2%) received a definite diagnosis, while 13 nodules (17.8%) were indeterminate. There was a statistically significant difference in the calcification classification between the malignant group and the benign group as well as the indeterminate group ( P<0.05). Among the malignant group, 29 patients underwent surgical treatment, with only 2 cases (8.0%) showing intermediate recurrence risk when surgery was performed more than three months after the initial FNAB. Upon reevaluation of the 31 initial FNAB samples from the malignant group, 9 samples (29.0%) exhibited mild cytological atypia, and 22 samples (71.0%) had poor quality specimens, mainly comprising fibrous and calcified components. Conclusions:For nodules initially classified as Bethesda Ⅲ, if suspicious ultrasound features persist or emerge, especially if microcalcifications are present, rFNAB should be performed after a follow-up period exceeding three months. However, during the puncture, multiple points should be targeted at the non-calcified areas of the nodule to enhance the accuracy and reliability of rFNAB.

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 incidence and risk factors of systemic allergic reactions induced by subcutaneous immunotherapy (SCIT) in patients undergoing SCIT injections in Peking Union Medical College Hospital (PUMCH). Methods: This is a single center retrospective cohort study. Using the outpatient information system of PUMCH, the demographic information and injection-related reaction data of patients undergoing SCIT injection in Allergy Department of PUMCH from December 2018 to December 2022 were retrospectively analyzed to count the incidence and risk factors of systemic allergic reactions caused by SCIT. Mann-Whitney nonparametric test or chi-square test was used for single-factor analysis, and multiple logistic regression was used for multiple-factor analysis. Results: A total of 2 897 patients received 18 070 SCIT injections in Allergy Department during the four years, and 40 systemic allergic reactions occurred, with the overall incidence rate of 0.22%. The incidence of systemic allergic reaction was 0.37% when using imported dust mite preparation and 0.15% when using domestic multi-component allergen preparation. The risk factors significantly related with SCIT-induced systemic allergic reactions in patients using imported dust mite preparation were age less than 18 years old (OR=3.186,95%CI: 1.255-8.085), highest injection concentration (OR value could not be calculated because all patients with systemic reactions were injected with highest concentration), and large local reaction in previous injection (OR=22.264,95%CI: 8.205-60.411). The risk factors for SCIT-induced systemic allergic reactions in patients using domestic allergen preparation were 5 or more types of allergens (OR=3.455,95%CI: 1.147-10.402), highest injection concentration (OR=3.794,95%CI: 1.226-11.740) and large local reaction in previous injection (OR=63.577,95%CI: 22.248-181.683). However, SCIT injection in pollen allergic patients during the pollen season did not show a correlation with systemic allergic reaction. Conclusion: The incidence of SCIT-induced systemic allergic reactions was low in the Chinese patient population of this study. Patients with one or more risk factors, such as multiple allergen injection, highest injection concentration, large local reaction in previous injection, should be given high attention and vigilance against systemic allergic reactions.

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: This study aimed to assess the associations between maternal drug use, cytochrome P450 ( CYP450) genetic polymorphisms, and their interactions with the risk of congenital heart defects (CHDs) in offspring. METHODS: A case-control study involving 569 mothers of CHD cases and 652 controls was conducted from November 2017 to January 2020. RESULTS: After adjusting for potential confounding factors, the results show that mothers who used ovulatory drugs (adjusted odds ratio [a OR] = 2.12; 95% confidence interval [ CI]: 1.08-4.16), antidepressants (a OR = 2.56; 95% CI: 1.36-4.82), antiabortifacients (a OR = 1.55; 95% CI: 1.00-2.40), or traditional Chinese drugs (a OR = 1.97; 95% CI: 1.26-3.09) during pregnancy were at a significantly higher risk of CHDs in offspring. Maternal CYP450 genetic polymorphisms at rs1065852 (A/T vs. A/A: OR = 1.53, 95% CI: 1.10-2.14; T/T vs. A/A: OR = 1.57, 95% CI: 1.07-2.31) and rs16947 (G/G vs. C/C: OR = 3.41, 95% CI: 1.82-6.39) were also significantly associated with the risk of CHDs in offspring. Additionally, significant interactions were observed between the CYP450genetic variants and drug use on the development of CHDs. CONCLUSIONS In those of Chinese descent, ovulatory drugs, antidepressants, antiabortifacients, and traditional Chinese medicines may be associated with the risk of CHDs in offspring. Maternal CYP450 genes may regulate the effects of maternal drug exposure on fetal heart development.
