Malignant tumors are one of the major diseases that endanger human life and health. Chinese medicine has unique advantages in clinical anti-tumor treatment. However, how to translate the anti-tumor effects of Chinese medicine into clinical practice is the core issue that must be addressed in the process of treating malignant tumors with traditional Chinese medicine (TCM). Unlike modern chemical drugs, the compatibility application of Chinese medicine is the key factor that determines whether Chinese medicine can achieve optimal anti-tumor efficacy and realize the goal of "enhancing efficacy and reducing toxicity". The formulation structure based on this compatibility is the basic form for the safe, efficient, and rational clinical use of anti-tumor Chinese medicine, and it mainly includes three categories: herb pairs, tri-herbal combinations, and compound compatibility. Although herb pairs have the characteristics of a simple structure and strong targeting (enhancing efficacy and reducing toxicity), they often have a single effect and cannot fully address the complex pathogenesis of tumors. As a result, herb pairs are rarely used alone in practice. Compared to herb pairs, tri-herbal combinations broaden the application scope of herbs in clinical treatment, but their therapeutic range remains limited. The traditional "sovereign, minister, assistant, and guide" compound prescription, which includes herb pairs and tri-herbal combinations, improves the efficacy of herbs in treating serious diseases, hypochondriasis, chronic diseases, and miscellaneous disorders. However, due to the limitations of its historical background, it has not been integrated with modern clinical practice and modern pharmacological research, which restricts the development of compound compatibility theory. With the emergence of modern medical technology, it has been combined with traditional compatibility theory of Chinese medicine to create an innovative modern compatibility theory. This includes the "aid medicine" theory derived from modern Chinese medicine pharmacology, which compensates for the inability of the "sovereign, minister, assistant, and guide" theory to accurately apply medicine. Additionally, the "state-targeted treatment based on syndrome differentiation" theory, developed from pharmacology and modern medicine, addresses the deficiency in disease cognition in the "sovereign, minister, assistant, and guide" theory. Under the guidance of these compatibility forms and theories, clinical anti-tumor Chinese medicine can exert its maximum anti-tumor efficacy, which is of great significance for the application of Chinese medicine in clinical tumor treatment.

Background::T-cell-mediated immunity is crucial for the effective clearance of viral infection, but the T-cell-mediated immune responses that are induced by booster doses of inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in people living with human immunodeficiency virus (PLWH) remain unclear.Methods::Forty-five PLWH who had received antiretroviral therapy (ART) for more than two years and 29 healthy controls (HCs) at Beijing Youan Hospital were enrolled to assess the dynamic changes in T-cell responses between the day before the third vaccine dose (week 0) and 4 or 12 weeks (week 4 or week 12) after receiving the third dose of inactivated SARS-CoV-2 vaccine. Flow cytometry, enzyme-linked immunospot (ELISpot), and multiplex cytokines profiling were used to assess T-cell responses at the three timepoints in this study.Results::The results of the ELISpot and activation-induced marker (AIM) assays showed that SARS-CoV-2-specific T-cell responses were increased in both PLWH and HCs after the third dose of the inactivated SARS-CoV-2 vaccine, and a similar magnitude of immune response was induced against the Omicron (B.1.1.529) variant compared to the wild-type strain. In detail, spike-specific T-cell responses (measured by the ELISpot assay for interferon γ [IFN-γ] release) in both PLWH and HCs significantly increased in week 4, and the spike-specific T-cell responses in HCs were significantly stronger than those in PLWH 4 weeks after the third vaccination. In the AIM assay, spike-specific CD4 + T-cell responses peaked in both PLWH and HCs in week 12. Additionally, significantly higher spike-specific CD8 + T-cell responses were induced in PLWH than in HCs in week 12. In PLWH, the release of the cytokines interleukin-2 (IL-2), tumour necrosis factor-alpha (TNF-α), and IL-22 by peripheral blood mononuclear cells (PBMCs) that were stimulated with spike peptides increased in week 12. In addition, the levels of IL-4 and IL-5 were higher in PLWH than in HCs in week 12. Interestingly, the magnitude of SARS-CoV-2-specific T-cell responses in PLWH was negatively associated with the extent of CD8 + T-cell activation and exhaustion. In addition, positive correlations were observed between the magnitude of spike-specific T-cell responses (determined by measuring IFN-γ release by ELISpot) and the amounts of IL-4, IL-5, IL-2 and IL-17F. Conclusions::Our findings suggested that SARS-CoV-2-specific T-cell responses could be enhanced by the booster dose of inactivated COVID-19 vaccines and further illustrate the importance of additional vaccination for PLWH.

Objective:To explore and screen the immunophenotypic characteristics of acute promyelocytic leukemia (APL) by multiparameter flow cytometry (MFC).Methods:A retrospective and descriptive study. A total of 130 acute myeloid leukemia (AML) patients who registrated in Hebei Yanda Lu Daopei Hospital were studied, among which there were 44 classical APL (cAPL), 24 microgranular variant of APL (APLv) and 62 non-APL patients (including NPM1 mut AML and AML with KMT2A rearrangement). MFC immunotyping was used to analyze and compare the median expression intensity (MEI) of side scatter (SSC), along with the ratio of the MEI on leukemic cells with those on lymphocytes (T/L MEIR), the median fluorescence intensity (MDFI) of CD34, myeloperoxidase (MPO), CD64 and CD9 on leukemic cells, as well as the ratios of these MDFIs on leukemic cells with those on lymphocytes (T/L MDFIR). Receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic efficiency of the multiparameters model for distinguishing cAPL and non-APL, APLv and non-APL. Results:The MEI and T/L MEIR of SSC in the cAPL group were higher than those in the APLv and non-APL groups ( P<0.05), and these two parameters in APLv group were higher than those in the non-APL group, respectively ( P<0.05). The MDFIs of CD34 in cAPL and APLv groups were higher than those in the non-APL group ( P<0.05), and the T/L MDFIR of CD34 was higher in APLv group than non-APL group ( P<0.05). The MDFIs of MPO and CD9, as well as the T/L MDFIRs in cAPL and APLv groups were both higher than those in the non-APL group, respectively ( P<0.05). The MDFI and T/L MDFIR of CD64 in the cAPL group were higher than those in non-APL group, respectively ( P<0.05). ROC curve results showed that the area under the curve (AUC) of MEI of SSC, the MDFI of CD64 and CD9, as well as the T/L MEIR of SSC and T/L MDFIR of CD9 were 0.932, 0.816, 0.893, 0.960 and 0.894 for diagnosing cAPL, respectively, and the AUC of these parameters were 0.725, 0.737, 0.791, 0.729 and 0.736 for diagnosis APLv, respectively ( P<0.05). Conclusion:MFC method can analyze and screen the immunophenotypic characteristics of APL for differential diagnosis of cAPL, APLv and non-APL patients.

Objective To investigate the impact of Pseudomonas aeruginosa(PA)infection on the function of pulmonary vascular endothelial cells,and explore the mechanism of this bacterium in exacerbating lung inflammation in mice.Methods Two hours after human lung microvascular endothelial cell(HULEC-5a)were infected with the PA strain PAO1,the mRNA levels of autophagy-related gene 5(ATG5),6-phosphofruc-to-2-kinase/fructose-2,6-bisphosphatase 3(PFKFB3),and calcium adhesion protein 5(CDH5)were deter-mined by reverse transcription real-time fluorescent quantitative PCR(RT-qPCR).The protein levels of ATG5,PFKFB3,and vascular endothelial calcium adhesion protein(VE-cadherin)were detected by immunofluores-cence.After the expression of ATG5 and PFKFB3 was respectively knocked down by small interfering RNA(siRNA),RT-qPCR was employed to measure the mRNA levels of ATG5,PFKFB3,and CDH5,and immunofluorescence to detect the protein levels of PFKFB3 and VE-cadherin.In addition,the lactate assay kit was used to determine the level of lactate in the cells.After mice were infected with PAO1,lung inflammation was assessed through his-topathological section staining.Confocal microscopy was employed to capture and analyze fluorescence-labeled PFKFB3 and VE-cadherin in endothelial cells.Results Compared with the control group,the HULEC-5a cells infected with PAO1 showed up-regulated mRNA and protein levels of PFKFB3(all P<0.05),down-regulated mRNA level of CDH5(P =0.023),disrupted continuity and down-regulated protein level of VE-cadherin(P<0.001),and elevated lactate level(P =0.017).Compared with PAO1-infected HULEC-5a cells,knocking down PFKFB3 led to the up-regulated mRNA level of CDH5(P =0.043),lowered lactate level(P =0.047),and restored continuity of VE-cadherin;knocking down ATG5 led to up-regulated mRNA and protein levels of PFKFB3(P =0.013 and P =0.003),elevated lactate level(P =0.015),and down-regulated mRNA level of CDH5(P =0.020)and protein level of VE-cadherin(P =0.001).The HE staining results showed obvious red blood cell leakage,inflammatory cell infiltration,alveolar septal widening,and partial detachment of vascu-lar endothelial cells in the alveoli of PA-infected mice.Immunofluorescence staining showed up-regulated expres-sion of PFKFB3 and decreased fluorescence signal of VE-cadherin in endothelial cells of infected mice compared with normal mice.Conclusion PA may regulate the PFKFB3 pathway via AGT5 to disrupt the function of pulmo-nary vascular endothelial cells,thereby exacerbating the inflammation in the lungs of mice.

Objective:To evaluate the changes of ventricular function in the twin-to-twin transfusion syndrome (TTTS) fetuses before and after fetoscopy laser photocoagulation (FLP) by fetal heart qualifiction (fetal HQ) technology.Methods:A total of 30 TTTS pregnant women who underwent FLP and delivered in the Third Affiliated Hospital of Zhengzhou University from January 2023 to November 2023 were prospectively selected as the TTTS group, including 30 donor fetuses and 30 recipient fetuses. The control group included 34 normal monochorionic diamniotic (MCDA) twins (68 fetuses) at the same gestational age. The changes of cardiac function of donor and recipient fetuses before and one day, one week and one month after FLP treatment were investigated by fetal HQ. The correlations between stage and global strain(GS) and fractional area change(FAC) of ventricle were analyzed. The inter-observer and intera-observer repeatability tests were performed.Results:①Before FLP treatment, fractional shortening(FS)10-24 of left ventricle and FS10-11 of right ventricle in donor group were lower than the control group (all P<0.05).GS, FAC, FS10-24 of left ventricle and GS, FAC, FS1-24 of right ventricle in recipient group were lower than the control group (all P<0.05). In the donor group, Quintero stage was moderately positively correlated with GS of right ventricle and moderately negatively correlated with FAC of right ventricle ( rs=0.535, -0.515; P=0.004, 0.006). But there were no correlation between Quintero stage and GS and FAC of left and right ventricle in recipient group (all P>0.05). ②After FLP treatment, the left ventricular systolic function of the donor group recovered to the normal level one day after operation ( P>0.05). But the FS16-24 of left ventricle were lower than the control group one week after operation, and the FS21-24 of left ventricle were still lower than the control group one month after operation(all P<0.05). One day after operation, the systolic function of the right ventricle in the donor group decreased, and GS, FAC and FS6-24 of the right ventricle were lower than the control group (all P<0.05). However, the right ventricular systolic function recovered to the normal level one week after operation ( P>0.05). ③After FLP, the systolic function of left ventricle and right ventricle recovered in recipient group, especially for right ventricle. One month after operation, only FS12-16 of left ventricle were lower than the control group ( P<0.05). But GS and FAC of left and right ventricle and 24 segments FS of right ventricle recovered to the control level (all P>0.05). ④The ICC of left and right ventricular parameters were greater than 0.75, indicating good repeatability ( P<0.05). Conclusions:Fetal HQ technology can sensitively evaluate fetal heart function in TTTS fetuses with good repeatability. Before FLP, the ventricular function of donor and recipient fetuses are affected to varying degrees.After FLP, the left and right ventricular function of the donor and recipient fetuses are improved to varying degrees and have different recovery rules.

ObjectiveOvarian cancer is the third most common gynecologic cancer worldwide, with the second highest mortality rate among gynecologic cancers, and age-standardized rates are gradually increasing in many low- and middle-income countries. At present, its etiology and pathogenesis are not clear. There are no obvious symptoms in the early stage, and when the symptoms become obvious, it often indicates the advanced stage. The 5-year survival rate of the advanced stage is only 17%, which poses a great threat to women's health. Therefore, an in-depth study of the etiology and pathogenesis of ovarian cancer is very important to the exploration of prevention and treatment methods for ovarian cancer. Based on the clinical characteristics of ovarian cancer in traditional Chinese and Western medicine, and combined with the existing evaluation methods of animal models, this study evaluated the animal model of ovarian cancer, and provided analysis and suggestions. MethodThis study searched China National Knowledge Infrastructure (CNKI), Wanfang data, VIP information database, and PubMed database using the keywords "ovarian cancer" and "animal model", excluded the articles that did not meet the criteria, and then classified the remaining studies. Combined with the clinical diagnostic criteria of Western medicine and traditional Chinese medicine syndrome differentiation, the related indicators of ovarian cancer animal models were assigned and the degree of agreement was evaluated. ResultThe use of the transplanted animal model exhibited the highest frequency, followed by that of the induced model. The degree of agreement of traditional Chinese medicine for each model was lower than that of Western medicine. The induced ovarian cancer model had a high degree of clinical agreement and was similar to human ovarian cancer in terms of tumor growth pattern, disease progression and complications, which is an ideal animal model of ovarian cancer. Although this animal model can simulate the etiology and pathogenesis of ovarian cancer to a certain extent and reflect some indicators of traditional Chinese and Western medicine, it lacks differentiation of traditional Chinese medicine syndromes. ConclusionOn the basis of the original model, the animal model of ovarian cancer was added with Qi deficiency syndrome, blood deficiency syndrome, Qi stagnation syndrome, blood stasis syndrome, heat-toxin syndrome, and Yang deficiency syndrome to establish an animal model combining traditional Chinese medicine disease and syndrome of ovarian cancer, which could better simulate the clinical actual situation of traditional Chinese and Western medicine and lay a solid foundation for the study of integrated traditional Chinese and Western medicine for the treatment of ovarian cancer.

OBJECTIVE
To study the anti-ulcerative colitis(UC) effect of Sargentodoxae Caulis and explore its mechanism.
METHODS
The UC mice model induced by dextran sodium sulfate was used to evaluate the anti-UC effect of Sargentodoxae Caulis. The ingredients of Sargentodoxae Caulis were obtained according to the CNKI and PubMed website, component targets were screened by SwissTargetPrediction database, GEO gene chip was used to extract UC differential genes, then a network of "ingredients-targets-disease" of the Sargentodoxae Caulis was constructed. After screening the core targets, protein interaction and cluster analysis, biological process and pathway enrichment analysis were performed, and the reliability of network analysis was preliminarily verified by molecular docking and literatures.
RESULTS
Sargentodoxae Caulis could significantly improve the disease activity index score, colon shortening and colonic histopathological changes of UC mice, and had a good anti-UC effect. The network analysis found that the core components of the anti-UC of Sargentodoxae Caulis include (+)-Dihydroxyurearetic acid, Isorhaponigenin and Pinosylvin, and 63 core targets, such as EGFR, STAT1 and LCK, regulating PI3K-Akt signal pathway and cancer proteoglycan and other related signal pathways of immune anti-inflammatory and anti-cancer, and it could affect the biological processes such as amino acid modification, kinase activity regulation, cell reaction and oxidative stress to treat UC. Molecular docking and literature showed that the constructed network had high reliability.
CONCLUSION
Sargentodoxae Caulis has a good anti-UC effect, and its mechanism may be closely related to the regulation of intestinal immune inflammation and cell proliferation, differentiation and migration. It has the characteristics of multi-component, multi-target and multi-way.
