This study aims to explore the effects of Buzhong Yiqi Decoction(BYD) on the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)-stimulator of interferon genes(STING) signaling pathway in the mouse model of autoimmune thyroiditis(AIT) and the mechanism of BYD in alleviating the immune injury. Forty-eight NOD.H-2~(h4) mice were assigned into normal, model, low-, medium-, and high-dose BYD, and selenium yeast tablets groups(n=8). Mice of 8 weeks old were treated with 0.05% sodium iodide solution for 8 weeks for the modeling of AIT and then administrated with corresponding drugs by gavage for 8 weeks before sampling. High performance liquid chromatography was employed to measure the astragaloside Ⅳ content in BYD. Hematoxylin-eosin staining was employed to observe the pathological changes in the mouse thyroid tissue. Enzyme-linked immunosorbent assay was employed to measure the serum levels of thyroid peroxidase antibody(TPO-Ab), thyroglobulin antibody(TgAb), and interferon-γ(IFN-γ). Flow cytometry was employed to detect the distribution of T cell subsets in the spleen. The immunohistochemical method was used to detect the expression of cGAS, STING, TANK-binding kinase 1(TBK1), and interferon regulatory factor 3(IRF3). Real-time PCR and Western blot were employed to determine the mRNA and protein levels, respectively, of markers related to the cGAS-STING signaling pathway in the thyroid tissue. The results showed that the content of astragaloside Ⅳ in BYD was(7.06±0.08) mg·mL~(-1). Compared with the normal group, the model group showed disrupted structures of thyroid follicular epithelial cells, massive infiltration of lymphocytes, and elevated levels of TgAb and TPO-Ab. Compared with the model group, the four treatment groups showed intact epithelial cells, reduced lymphocyte infiltration, and lowered levels of TgAb and TPO-Ab. Compared with the normal group, the model group showed increases in the proportions of Th1 and Th17 cells, a decrease in the proportion of Th2 cells, and an increase in the IFN-γ level. Compared with the model group, the four treatment groups presented decreased proportions of Th1 and Th17 cells and lowered levels of IFN-γ, and the medium-dose BYD group showed an increase in the proportion of Th2 cells. Compared with the normal group, the modeling up-regulated the mRNA levels of cGAS, STING, TBK1, and IRF3 and the protein levels of cGAS, p-STING, p-TBK1, and p-IRF3. Compared with the model group, the four treatment groups showed reduced levels of cGAS, STING, TBK1, and IRF3-positive products, down-regulated mRNA levels of cGAS, STING, and TBK1, and down-regulated protein levels of cGAS and p-STING. The high-dose BYD group showed down-regulations in the mRNA level of IRF3 and the protein levels of p-TBK1 and p-IRF3. The above results indicate that BYD can repair the imbalance of T cell subsets, alleviate immune injury, and reduce thyroid lymphocyte infiltration in AIT mice by inhibiting the cGAS-STING signaling pathway.

OBJECTIVE: To investigate the effect of non-chemotherapy strategy of retinoic acid (ATRA) combined with arsenic trioxide (ATO) on the survival of patients with acute promyelocytic leukemia (APL). METHODS: The data of APL patients with complete information diagnosed in the hematology department of our hospital from June 2009 to November 2024 were retrospective analyzed. All patients in the non-CHT group received ATRA-ATO induction, consolidation and maintenance therapy. Patients in the CHT group received ATRA-ATO+chemotherapy induction therapy, followed by 3 cycles of ATRA-ATO+CHT consolidation therapy and 6-10 cycles of ATRA-ATO maintenance therapy. The primary endpoint was event-free survival (EFS). Secondary endpoints included overall survival (OS), remission rate, differentiation syndrome (DS) and safety. RESULTS: There were 182 patients with APL and 15 patients with early death (ED), accounting for 8.24%, which was related to age and risk stratification. There was no significant difference in remission rate between the non-CHT group and the CHT group (P =0.486). As of February 2025, the median follow-up time of patients was 39.5 months. The EFS of the non-CHT group was significantly better than that of the CHT group (P =0.038). There was no significant difference in OS between the two groups (P =0.442). Subgroup analysis showed that EFS in the non-CHT was longer in standard-risk patients (P =0.012). There was no significant difference in EFS (P =0.585) and OS (P =0.473) between the CHT and non-CHT groups in high-risk patients. The incidence of mild DS was 23.6% in the non-CHT group and 23.1% in the CHT group, respectively, with no statistically significant difference(P =0.937). Compared with CHT group, the incidence of serious adverse events was lower in the non-CHT group. CONCLUSION The non-chemotherapy regimen of ATRA combined with ATO is a feasible method to cure APL patients.

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.

OBJECTIVES: This study aims to analyze the clinical symptoms and imaging manifestations in patients with temporomandibular disorder syndrome (TMD), who are sensitive to sudden temperature drop. METHODS: One hundred and nineteen patients with TMD who attended the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital from December 2022 to December 2023 were included, including 44 males and 75 females, with a mean age of 32.4±13.7 years.The questionnaire was used to determine whether they were sensitive to temperature drop, and the TMD patients were divided into a temperature plunge-sensitive group and a temperature drop insensitive group. The clinical symptoms and imaging manifestations of patients in the two groups were observed. SPSS 25.0 was used for statistical analysis. RESULTS: There was no statistically significant difference between the gender and age of patients in the temperature plunge-sensitive group (50 patients) and the insensitivity group (69 patients) (P>0.05). The percentage of patients with pain was slightly higher in the temperature plunge-sensitive group [86.0% (43/50)] than in the insensitive group [68.1% (47/69)], and the difference was statistically significant (χ²=5.031, P=0.025), while the differences in joint murmur and mouth opening limitation between the two groups were not statistically significant. A total of 238 lateral joints were detected in both groups, the percentage of osteoarthropathic imaging changes was significantly higher in the temperature plunge-sensitive group [82.0% (82/100)] than in the insensitive group [53.6% (74/138)] (χ²=20.675, P<0.001). Magnetic imaging showed that the percentage of joint effusion was higher in patients in the temperature plunge-sensitive group [66.0% (33/50)] than in the insensitive group [42.0% (29/69)], and the difference was statistically significant (χ²=5.602, P=0.018). CONCLUSIONS TMD patients with maxillofacial pain symptoms, joint effusions, and abnormal imaging of osteoarticular structures are more likely to be sensitive to sudden temperature drops.

Objective To study the effect of hesperetin(HSP)on renal ischemia-reperfusion injury(RIRI)in rats and its mechanism.Methods Fifty male SD rats were randomly divided into five groups:sham group,model group(renal ischemia-reperfusion injury I/R),HSP pretreatment(HSP+I/R)group,all-trans retinoic acid pretreatment(ATRA+I/R)group,HSP and ATRA pretreatment(HSP+ATRA+1/R)group.Each group had 10 rats.The sham group only exposed both kidneys by opening the abdominal cavity.In other groups,the RIRI model was established by occluding the bilateral renal pedicles for 45 min,followed by reperfusion for 24 h.Hematoxylin-eosin staining(HE)was used to ascertain the extent of kidney injury.The microplate method was used to measure serum creatinine(Scr)levels,while the urease method was used to measure blood urea nitrogen(BUN)levels.Enzyme-linked immunosorbent assay(ELISA)was used to detect the contents of interleukin-6(IL-6),interleukin-1β(IL-1 β)and tumor necrosis factor-α(TNF-α)in the serum.The kit method was used to examine the levels of superoxide dismutase(SOD),glutathione(GSH),malondialdehyde(MDA)and catalase(CAT)in kidney tissue.The Western blot analysis was conducted to detect the expression of nuclear factor erythroid 2 related factor 2(Nrf2)and its downstream antioxidant proteins heme oxygenase-1(HO-1)and quinone oxide reductase 1(NQO1)in renal tissues.Results The scores for renal tubule damage in sham,I/R and HSP+I/R groups were 0.20±0.45,4.20±0.84 and 2.40±0.55;Scr contents were(55.52±11.23),(207.10±19.22)and(105.60±18.11)μmol·L-1;IL-6 contents were(33.66±6.83),(172.50±8.09)and(105.40±10.03)pg·mL-1.The SOD levels in sham,I/R,HSP+I/R,ATRA+I/R and HSP+ATRA+I/R groups were(57.04±3.44),(37.29±3.60),(51.61±9.41),(32.55±5.58)and(37.40±3.66)U·mg·prot-1;the relative expression levels of Nrf2 were 0.37±0.24,0.57±0.28,1.31±0.34,0.44±0.17 and 0.77±0.25;the relative expression levels of HO-1 protein were 0.26±0.14,0.57±0.30,1.32±0.61,0.53±0.28 and 0.67±0.50.There was significant difference in renal tubule damage score,Scr,IL-6 and SOD indexes in I/R group compared to sham group(P＜0.05,P＜0.01).The above indexes were statistically significant between HSP+I/R group and I/R group(P＜0.05,P＜0.01).Conclusion The activation of HSP may stimulate the Nrf2-antioxidant response element(ARE)pathway,enhance the expression of downstream antioxidant proteins,mitigate the renal damage caused by oxidative stress,and ultimately improve RIRI.

Objective To explore the mechanism of Zhuangxuan Yin in the treatment of children with H1N1 pneumonia through regulating gut microbiota mediated by p38 mitogen-activated protein kinase(p38-MAPK)pathway.Methods A BALB/c mouse model of H1N1 pneumonia was prepared using the H1N1 influenza virus allantoic solution for nasal drop.The model was randomly separated into 5 groups:model group,Zhuangxuan Yin low-,medium-and high-dose groups,and high-dose Zhuangxuan Yin(28.66 g·kg-1)+anisomycin(10 mg·kg-1)group.The control group was infused with sterile physiological saline of equal volume using the same method.After treatment with Zhuangxuan Yin and anisomycin,the lung index of mice in each group was measured,and HE staining was applied to detect the pathological morphology of lung and large intestine tissues.16SrRNA gene sequencing was applied to detect the structural difference of gut microbiota in mice of each group.Enzyme-linked immunosorbent assay(ELASA)was applied to measure the levels of tumor necrosis factor-α(TNF-α),interleukin(IL)-4,IL-6,and IL-1β in bronchoalveolar lavage fluid(BALF)and large intestine tissue of mice in each group.Western Blot was applied to detect the expression of p38-MAPK pathway-related proteins in lung and large intestine tissues of mice in each group.Results Compared with the control group,the lung and large intestine tissues of the model group mice showed obvious pathological damage,the lung index,pathological score of lung and large intestine,ACE index,Shannon index,abundance of class Clostridia,the levels of TNF-α,IL-4,IL-6,and IL-1β in BALF and large intestine tissues,and p-p38-MAPK/p38-MAPK in lung and large intestine tissues increased(P＜0.05).The abundance of class Bacteroidales decreased(P＜0.05).Compared with the model group,the pathological damage in the lung and large intestine tissues of mice in the Zhuangxuan Yin low-,medium-and high-dose groups were reduced.The lung index,pathological score of lung and large intestine,ACE index,Shannon index,abundance of class Clostridia,the levels of TNF-α,IL-4,IL-6,and IL-1β in BALF and large intestine tissues,and p-p38-MAPK/p38-MAPK in lung and large intestine tissues decreased(P＜0.05),the abundance of class Bacteroidales increased(P＜0.05),and in a dose-dependent manner(P＜0.05).Compared with the high-dose Zhuangxuan Yin group,the pathological damage in the lung and large intestine tissues of mice in the high-dose Zhuangxuan Yin+anisomycin group was aggravated,the lung index,pathological score of lung and large intestine,ACE index,Shannon index,abundance of class Clostridia,the levels of TNF-α,IL-4,IL-6,and IL-1β in BALF and large intestine tissues,and p-p38-MAPK/p38-MAPK in lung and large intestine tissues increased(P＜0.05),and the abundance of class Bacteroidales decreased(P＜0.05).Conclusion Zhuangxuan Yin can improve the imbalance of intestinal microbiota in H1N1 pneumonia mice by inhibiting p38-MAPK signal activation,thereby inhibiting inflammation and reducing lung and large intestine tissue damage in mice,which may have a therapeutic effect on children with H1N1 pneumonia.

Objective:To identify the risk factors for intraoperative hemorrhage and transfusion in patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:A total of 1, 442 patients, regardless of gender, of American Society of Anesthesiologists Physical Status classification≥Ⅱ, scheduled for elective OPCABG from June 7, 2021 to March 8, 2023, were enrolled in a prospective, observational study. Patients′ general characteristics, preoperative hemodynamics, preoperative blood routine, duration of operation, the number of transplanted vessels, intraoperative application of vasoactive agents, intraoperative consumption of crystalloid and colloid, urine volume, blood products, use of tranatemic acid and ulinastatin were collected. Univariable and multiple linear regression models were used to screen the risk factors for intraoperative blood loss and infusion volume of concentrated red blood cell (CRBC), and univariable and multivariable logistic regression models were used to screen the risk factors for intraoperative CRBC infusion requirement.Results:One thousand four hundred and twenty patients were finally included. Prolonged operation duration, increased number of transplanted vessels and older age were risk factors for intraoperative blood loss, while male, increased intraoperative usage of fresh frozen plasma (FFP), increased urine volume, and application of ulinastatin and tranexamic acid were protective factors for intraoperative blood loss in OPCABG patients ( P<0.05). Prolonged operation duration and increased intraoperative usage of FFP were risk factors for intraoperative CRBC transfusion volume, while elevation of preoperative hemoglobin levels was a protective factor for intraoperative CRBC transfusion volume in OPCABG patients ( P<0.05). Prolonged operation duration and increased intraoperative usage of FFP were risk factors for intraoperative CRBC infusion requirement, while increased body mass index, elevation of preoperative hemoglobin levels and application of ulinastatin were protective factors for CRBC infusion requirement ( P<0.05). Conclusions:Prolonged operation duration, increased number of transplanted vessels and older age are risk factors for intraoperative blood loss, and increased intraoperative usage of FFP, increased urine volume, and application of ulinastatin and tranexamic acid are protective factors for intraoperative blood loss in OPCABG patients. Prolonged operation duration and increased intraoperative usage of FFP are risk factors for intraoperative CRBC infusion requirement and transfusion volume, elevation of preoperative hemoglobin levels is a protective factor for intraoperative CRBC infusion volume, and increased body mass index, elevation of preoperative hemoglobin levels and intraoperative application of ulinastatin are protective factors for intraoperative CRBC infusion requirement in patients undergoing OPCABG.

Quercetin (Que) is a flavonoid compound widely distributed in nature with various biological activities.Its anti-inflammatory effect plays a crucial role in many diseases,closely related to its regula-tion of histone post-translational modifications.However,there have been no detailed reports on the anti-inflammatory effects of quercetin regulating histone post-translational modifications.In this study,we first investigated the effect of quercetin on the M1 macrophages polarization.The results showed that quercetin can significantly down-regulate the levels of interleukin-1β(IL-1β) and interleukin-6 (IL-6 ) in M1 macrophages.Next,we used the super stable isotope labeling by amino acids in cell culture (super-SI-LAC) method derived from SILAC technology based on mass spectrometry to systematically analyze the post-translational modification levels of histone in macrophages treated with quercetin.A total of 30 his-tone modification sites were quantified,of which 12 histone lysine acetylation marks were significantly downregulated and 4 lysine methylation sites were upregulated (fold change>1.2,P<0.05),and some sites were verified by Western blot (WB),which was consistent with the mass spectrometry results.In conclusion,a comprehensive analysis of quercetin on regulating macrophage histone modifications in this study provides reliable data references and new insights for studying its anti-inflammatory mechanism.
