OBJECTIVE: To investigate the efficacy and safety of diagnostic-driven therapy for invasive fungal disease(IFD) in patients with myeloid hematologic malignancies. METHODS: A retrospective analysis was conducted on the clinical data of 91 patients with myeloid hematologic malignancies who received diagnostic-driven therapy for IFD at the Second Hospital of Anhui Medical University from January 1, 2020 to December 31, 2023. The patients were divided into two groups based on medication: 44 patients in the caspofungin group and 47 patients in the voriconazole group. The clinical efficacy and adverse reactions of the two groups were compared and analyzed. RESULTS: The overall response rates in the caspofungin and voriconazole groups were 67.4% and 60.0%, respectively. Among patients who transitioned to diagnostic-driven therapy following prophylactic or empirical treatment with triazole antifungal agents, the response rate of the caspofungin group was significantly higher than that of the voriconazole group (76.9% vs 35.3%, P <0.05). A total of 9 patients in both groups experienced adverse reactions, and no grade III or higher adverse reactions occurred. The incidence of grade I-II adverse reactions in the caspofungin group was lower than in the voriconazole group (2.3% vs 17.0%, P <0.05). CONCLUSION In patients with myeloid hematologic malignancies, caspofungin and voriconazole demonstrate comparable clinical efficacy in diagnostic-driven therapy for IFD, but caspofungin is associated with a lower incidence of adverse reactions. Caspofungin exhibits significant effectiveness when initiating diagnostic-driven therapy after prophylactic or empirical treatment with broad-spectrum triazole antifungal agents.

Objective:To explore the changes in number and immune function of mucosal-associated invariant T (MAIT) cells in peripheral blood of patients with newly diagnosed acute myeloid leukemia (AML),and its correlation with the occurrence and development of AML. Methods:Seventy-five clinical samples of patients with newly diagnosed AML and 48 healthy control samples in our hospital from January 2022 to February 2023 were included. Multiparametric flow cytometry was used to detect the number of MAIT cells,membrane surface markers,effector phenotypes and functional indicators in the samples. Results:Compared with healthy controls,the percentage of MAIT cells in CD3+T cells in peripheral blood of newly diagnosed AML patients was significantly reduced (P<0.001). The percentage of MAIT cells in all CD3+T cells in bone marrow of AML patients was similar to that in peripheral blood (P>0.05). Most of MAIT cells in peripheral blood of AML patients were effector memory T cells. Compared with healthy controls,the proportion of effector memory MAIT cells decreased (P<0.05),while the proportion of terminally differentiated effector memory MAIT cells and PD-1+MAIT cells increased significantly (both P<0.05). AML patients' peripheral blood MAIT cells expressed significantly higher levels of granzyme B and perforin than healthy controls (both P<0.05),and secreted significantly lower levels of cytokines such as gamma interferon and tumor necrosis factor α than healthy controls (both P<0.001). Conclusion:Compared with healthy controls,the proportion of MAIT cells in AML patients is reduced and the expression of functional markers is abnormal,suggesting that their function is impaired and may be involved in the occurrence and development of AML.

For the treatment of atrial fibrillation,Professor WU Wei innovatively put forward the theory of heart-blood-vessels trinity and the theory of stasis-toxin causing palpitation.It is believed that atrial fibrillation is caused by stasis and toxin,and affects the heart,blood and vessels.The core pathogenesis of atrial fibrillation is due to qi stagnation,blood stasis and toxin.The treatment for atrial fibrillation should be closely based on the pathogenesis,the therapeutic principles of treating from the perspective of stasis and together by removing toxin gradually is advocated.And the therapy of regulating qi,activating blood and removing stasis is also the way to remove toxin.The medication is based on the modified Taoren Honghua Decoction,which is mainly composed of Persicae Semen,Carthami Flos,Chuanxiong Rhizoma,Corydalis Rhizoma,Rehmanniae Radix,Paeoniae Radix Rubra,Salviae Miltiorrhizae Radix et Rhizoma,Jujubae Fructus,Puerariae Lobatae Radix,Nardostachyos Radix et Rhizoma,Ostreae Concha,Poria,and Polygonati Odorati Rhizoma.According to the characteristics of Lingnan climate and atrial fibrillation mostly being easy to affect the emotions,the pungent drugs in the prescription are usually removed,and the specific herbal pair of Puerariae Lobatae Radix-Nardostachyos Radix et Rhizoma is added to remove toxin according to the differentiation of disease.Moreover,for the treatment of atrial fibrillation,Professor WU Wei also adopts traditional Chinese medicine(TCM)external treatment such as foot bath,acupuncture and moxibustion,and physical-breathing exercise as well as health-care methods for comprehensive regulation,relieving the toxin and restoring the original qi.During the treatment atrial fibrillation,Professor WU Wei follows the principle of precise intervention and comprehensive regulation with Chinese medicine,so as to achieve the purpose of eliminating symptoms,restoring sinus rhythm and improving physical constitution.The thoughts of Professor WU Wei for the syndrome differentiation and treatment of atrial fibrillation will provide reference for the treatment of atrial fibrillation with TCM.

Based on the strategy of metabolomics combined with bioinformatics, this study analyzed the potential allergens and mechanism of pseudo-allergic reactions (PARs) induced by the combined use of Reduning injection and penicillin G injection. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). Based on UPLC-Q-TOF/MS technology combined with UNIFI software, a total of 21 compounds were identified in Reduning and penicillin G mixed injection. Based on molecular docking technology, 10 potential allergens with strong binding activity to MrgprX2 agonist sites were further screened. Metabolomics analysis using UPLC-Q-TOF/MS technology revealed that 34 differential metabolites such as arachidonic acid, phosphatidylcholine, phosphatidylserine, prostaglandins, and leukotrienes were endogenous differential metabolites of PARs caused by combined use of Reduning injection and penicillin G injection. Through the analysis of the "potential allergen-target-endogenous differential metabolite" interaction network, the chlorogenic acids (such as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, and isochlorogenic acid A) and β-lactam allergens in the combination of the two may be mainly regulated by PLD1, PLA2G12A and CYP1A1. The three upstream signal target proteins mainly activate the arachidonic acid metabolic pathway, promote the degranulation of mast cells, release downstream endogenous inflammatory mediators, and induce PARs.

Objective:To investigate the expression of KCTD8 gene in breast ductal carcinoma and its correlation with clinical factors and prognosis.Methods:Immunohistochemistry technology(IHC)were employed to detect protein expression levels of KCTD8 in 27 pairs of breast ductal carci-noma and its paired adjacent tissues.Analyzing the correlation between changes in KCTD8 expres-sion of protein and clinical factors using statistical techniques.RNA expression and methylation data of breast cancer(including intraductal cancer)were analysed from TCGA database.Result:The pro-tein expression of KCTD8 gene in 27 pairs of breast ductal carcinoma tissues showed a decreasing trend compared to adjacent tissues(P＜0.05),and the decreased expression level of protein was cor-related with the tumor size of patients(P＜0.05).The analysis results of the TCGA database indicate that the expression and hypemethylation of KCTD 8 gene in breast cancer(including intraductal can-cer)tissues affected the prognosis of patients.Conclusion:The reduced protein expression level of KCTD8 gene in breast ductal carcinoma may be involved in the development and affect the prog-nosis of patients.

The number of type 2 diabetes(T2DM)accounts for more than 90％of all Diabetes mellitus(DM).The decrease of islet β cell mass and dysfunction are the core links of T2DM.With the prolongation of the course of disease,the number and function of β cells are gradually attenuated,and the damage mechanism has not been elucidated.At present,it is believed that it is closely related to metabolic stress,abnormal regulation of insulin secretion,changes in islet microenvironment,mitochondrial damage,glycolipid toxicity and dedifferentiation of islet β cells.Therefore,the mechanism of islet β cell damage in T2DM is summarized and elaborated in order to provide some reference for the precise intervention of T2DM.

Objective To provide a longitudinal evaluation tool based on the frequency of aggressive be-havior for the aggression assessment of schizophrenia patients.Methods The Life History of Aggression was translated and revised to form the Life History of Aggression-Chinese Version(LHA-CV)based on 369 patients diagnosed with schizophrenia in the Chengdu community and compulsory medical insti-tution.The reliability of LHA-CV was analyzed by means of split-half reliability,test-retest reliability and inter-evaluator consistency.The validity was analyzed by item analysis,construct validity and crite-rion validity.Results Item analysis found that LHA-CV had good homogeneity and discriminant validity.Exploratory factor analysis found that the Kaiser-Meyer-Olkin(KMO)test value was 0.80,and the Bartlett's sphericity test χ2=1203.46(P<0.05),and it revealed four factors including non-physical ag-gression,physical aggression,self-directed aggression and antisocial behavior/consequences.The factor loadings for all 11 items were greater than 0.40.Confirmatory factor analysis was performed on the factor model,Chi-square degree of freedom(χ2/df)was 3.61,root mean square error of approxima-tion(RMSEA)was 0.07,goodness-of-fit index(GFI)was 0.92,comparative fit index(CFI)was 0.90,incremental fit index(IFI)was 0.90,and the discriminant validity of each factor was good.The criterion validity test showed the total score of LHA-CV was positively correlated with the aggressive behavior level of MacArthur Community Violence Instrument,the total score of Buss-Perry Aggression Scale,and the score of Antisocial Personality Disorder Subscale of Personality Diagnostic Question-naire-4th Edition Plus(PDQ-4+_ASPD,P<0.05).The Cronbach's α coefficient of non-physical aggres-sion,physical aggression,self-directed aggression,antisocial behavior/consequences and LHA-CV total score were 0.82,0.73,0.74,0.56 and 0.79,respectively.The test-retest reliability,Spearman-Brown split-half reliability and intra-class correlation coefficient of LHA-CV total score were 0.82(P<0.05),0.66 and 0.99,respectively.Conclusion LHA-CV has good reliability and validity,and can be used as an evaluation tool for longitudinally assessing aggressive behavior in schizophrenia patients.

Objective: To compare the prognosis and perioperative situation of patients with stage Ⅱ endometrial cancer (EC) between radical hysterectomy/modified radical hysterectomy (RH/mRH) and simple hysterectomy (SH). Methods: A total of 47 patients diagnosed EC with stage Ⅱ [International Federation of Gynecology and Obstetrics (FIGO) 2009] by postoperative pathology, from January 2006 to January 2021 in Peking University People's Hospital, were analyzed retrospectively. The patients were (54.4±10.7) years old, and the median follow-up time was 65 months (ranged 9-138 months). They were divided into RH/mRH group (n=14) and SH group (n=33) according to the scope of operation. Then the prognosis of patients between the groups were compared, and the independent prognostic factors of stage Ⅱ EC were explored. Results: (1) The proportions of patients with hypertension in RH/mRH group and SH group were 2/14 and 45% (15/33), the amounts of intraoperative blood loss were (702±392) and (438±298) ml, and the incidence of postoperative complications were 7/14 and 15% (5/33), respectively. There were significant differences (all P<0.05). (2) The median follow-up time of RH/mRH group and SH group were 72 vs 62 months, respectively (P=0.515). According to Kaplan-Meier analysis and log-rank method, the results showed that there were no significant difference in 5-year progression-free survival (PFS) rate (94.3% vs 84.0%; P=0.501), and 5-year overall survival rate (92.3% vs 92.9%; P=0.957) between the two groups. Cox survival analysis indicated that age, pathological type, serum cancer antigen 125 (CA₁₂₅), and estrogen receptor (ER) status were associated with 5-year PFS rate (all P<0.05). But the scope of hysterectomy (RH/mRH and SH) did not affect the 5-year PFS rate of stage Ⅱ EC patients (P=0.508). And level of serum CA₁₂₅ and ER status were independent prognostic factors for 5-year PFS rate (all P<0.05). Conclusions: This study could not find any survival benefit from RH/mRH for stage Ⅱ EC, but increases the incidence of postoperative complications. Therefore, the necessity of extending the scope of hysterectomy is questionable.

Objective: To investigate the association between triiodothyronine (T₃) and inflammatory factors, and its potential effect on long-term outcomes in hospitalized patients with heart failure (HF). Methods: A total of 2 475 patients with HF admitted in Heart Failure Care Unit were consecutively enrolled in this retrospective cohort study from December 2006 to June 2018. Patients were divided into low T₃ syndrome group (n=610, 24.6%) and normal thyroid function group (n=1 865, 75.4%). The median follow-up time was 2.9 (1.0, 5.0) years. A total of 1 048 all-cause deaths were recorded at the final follow-up. The effects of free T₃ (FT₃) and high-sensitivity C-reactive protein (hsCRP) on the risk of all-cause death were evaluated by Cox regression analysis and Kaplan-Meier analysis. Results: The age of the total population was 19-95 (57±16) years, 1 823 cases (73.7%) were male. Compared to those with normal thyroid function, albumin [(36.5±5.4) vs. (40.7±4.7) g/L], hemoglobin [(129.4±25.1) vs. (140.6±20.6) g/L], total cholesterol [3.6 (3.0, 4.4) vs. 4.2 (3.5, 4.9) mmol/L] (all P<0.001) were lower, Whereas age [(60.5±16.0) vs. (55.2±15.4) years], creatinine [105.0 (83.6, 137.0) vs. 87.8 (75.6, 106.3) mmol/L], log N-terminal B-type natriuretic peptide [(8.2±1.3) vs. (7.2±1.4) ng/L] were higher in LT₃S patients (all P<0.001). In Kaplan-Meier survival analysis, patients with lower FT₃ and higher hsCRP had significantly lower cumulative survival (P<0.001), lower FT₃ combined with higher hsCRP subgroup had the highest risk of all-cause death (P_trend<0.001). In multivariate Cox regression analysis, LT₃S was an independent predictor of all-cause mortality (HR=1.40, 95%CI 1.16-1.69, P<0.001). Conclusion: LT₃S is an independent predictor of poor prognosis in patients with heart failure. FT₃ combined with hsCRP improve the predictive value of all-cause death in hospitalized patients with heart failure.
