Objective To investigate the protective effect of cardamomine(CAR)on anthracycline-induced cardiotoxicity in rats by regulating the pyroptosis mediated by Notch/nuclear factor-κB(NF-κB)signal pathway.Methods The rat model of cardiotoxicity was established by intraperitoneal injection of doxorubicin(DOX).The model rats were randomly divided into DOX group,CAR-L group,CAR-H group and Jagged1 group.Another 10 rats were taken as the control group.The control group and the DOX group were given the same amount of 0.9％NaCl.The CAR-L group and CAR-H group were given 40 and 80 mg·kg-1 CAR by gavage,respectively.The Jagged1 group was given 80 mg·kg-1 CAR+and 25 ng·kg-1 Jagged1 by gavage once a day for 4 weeks.Myocardial injury markers creatine kinase isoenzyme(CK-MB)and troponin Ⅰ(cTn Ⅰ)were detected by kit.The expression of pyroptosis protein Nod-like receptor protein 3(NLRP3)and desquamate D(GSDM-D)were observed by immunohistochemistry.The expression of Notch1 and phosphorylated NF-κB p65(p-NF-κB p65)protein in myocardial tissue was detected by Western blotting.Results The levels of CK-MB in control group,DOX group,CAR-L group,CAR-H group and Jagged1 group were(48.51±5.39),(175.93±13.27),(106.83±9.73),(83.71±8.39)and(126.08±9.74)U·L-1;the levels of cTn Ⅰ were(1.95±0.18),(12.46±1.83),(7.15±0.64),(4.13±0.38)and(8.01±0.78)ng·mL-1;the average optical density of NLRP3 protein were 0.19±0.07,0.36±0.05,0.25±0.05,0.21±0.03 and 0.31±0.06;the average optical density of GSDM-D were 0.18±0.04,0.43±0.06,0.24±0.03,0.19±0.04 and 0.32±0.05.There were significant differences in the above indexes between DOX group and control group(all P＜0.05).There were significant differences in the above indexes between CAR-L group,CAR-H group and DOX group(all P＜0.05),and there were significant differences between CAR-L group and CAR-H group(all P＜0.05).The above indexes in Jagged1 group were significantly different from those in CAR-H group(all P＜0.05).Conclusion CAR can improve myocardial injury in DOX cardiotoxic rats,reduce oxidative stress,inflammatory reaction and pyroptosis,and its mechanism may be related to the inhibition of Notch/NF-κB pathway.

Objective:To investigate the current status of exercise fear in patients with chronic heart failure (CHF) and explore the different potential classifications and influencing factors of exercise fear, in order to provide theoretical basis for formulating targeted interventions.Methods:The subjects of this study were 278 patients with CHF treated in the Department of Cardiology, the First Affiliated Hospital of Xinjiang Medical University from July 2023 to November 2023 using convenience sampling method. A questionnaire survey was conducted using a general information questionnaire, Fear of Activity in Patients with Chronic Heart Failure, Cardiac Exercise Self-Efficacy Instrument, Personal Support Scale From Family, and Multidimensional Fatigue Index-20. Latent profile analysis to identify potential subtypes of motor fear in patients, and unordered multiple logistic regression to evaluate the influencing factors of different subtypes were used.Results:Totally 278 valid questionnaires were collected, including 96 females and 182 males, with a majority aged between 60 and 74 years old, with 114 cases accounting for 41.0%. The 278 CHF patients had a fear of movement score of (34.78 ± 13.17) points were divided into three potential categories based on their fear of movement: low-level fear of movement group (107 cases, 38.5%), moderate fear of movement group (108 cases, 38.8%), and high-level fear of movement group (63 cases, 22.7%). Disordered multiple logistic regression analysis showed that family support level ( OR = 2.520), exercise self-efficacy ( OR = 0.913), and fatigue ( OR = 1.065) were significant influencing factors for high-level exercise fear in CHF patients (all P<0.05), while age, education level, disease course, number of coexisting diseases, family support level, exercise self-efficacy, and fatigue were significant influencing factors for high-level exercise fear in CHF patients ( OR values ranged from 0.007 to 6.292, all P<0.05). Conclusions:There are three potential categories of exercise fear in patients with CHF. Medical staff should develop targeted intervention plans based on the characteristics of different categories of patients to reduce their level of exercise fear.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Coronary artery fistula(CAF)is defined as the direct connection between coronary artery and cardiac cavity,great vessel or other vascular structures.Most CAF are congenital and often present as persistent murmur in asymptomatic children.Although abnormal shunt of most coronary fistulas has little effect on hemodynamics,some larger fistulas can also lead to a series of complications,such as congestive heart failure.Therefore,closed CAF has been recommended to treat or prevent myocardial ischemia,congestive heart failure,endarteritis,arrhythmia,thromboembolism,aneurysm dilatation and rupture and other complications.CAF is a rare congenital heart disease,and bilateral CAF originating from two coronary arteries is even rarer.At present,there are rare systematic reports on bilateral CAF.Therefore,a case of huge bilateral CAF at the same site was reported,and systematically,this kind of case was summarized,so as to improve the clinical attention of diagnosis and treatment of this kind of CAF.Nowadays,some new interventional devices and technologies are emerging with the continuous progress of cardiovascular interventional technology,making the treatment more accurate,safe and effective.At the same time,there is also a clearer understanding of the indications and operating standards for interventional treatment,which is more operable and predictable during the treatment process.Therefore,interventional treatment of CAF may partially replace surgical treatment as the preferred treatment method.

Objective:To analyze the prognostic value of del(1p32)in patients with newly diagnosed multiple myeloma(MM).Methods:The clinical data of 341 newly diagnosed MM attended in Jiangsu Province Hospital were retrospective analyzed.Clinical characteristic combined with genetic features,especially del(1p32),were analyzed for survival and prognostic of patients.Results:Among the 341 patients with newly diagnosed MM,24(7.0％)patients were del(1p32)positive.The progression-free survival(PFS)and overall survival(OS)were significantly shorter in MM patients with del(1p3 2)than those without de1(1p32)(PFS:P＜0.001;OS:P＜0.001).The COX proportional-hazards model showed that del(1 p32)was an independent risk factor for PFS and OS of patients with MM.The patients with both 1q21 gain/amplification and del(1p32),as"double-hit chromosome 1",have worse prognosis than those with only 1q21 gain/amplification or only del(1 p32)(PFS:P＜0.001;OS:P＜0.001).Conclusion:Del(1p32)is an independent risk factor for PFS and OS of patients with MM.Del(1p32)detection should be widely used in the prognostic analysis for newly diagnosed MM patients.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Breast cancer has become the most prevalent malignant tumor among women, putting the health of women at serious risk. Screening for lead compounds in the active ingredients of plant that are effective and less toxic continues to be an important strategy for treating breast cancer. Gerbeloid J, a coumarin isolated from Gerbera piloselloides (L.) Cass., showed significant anti-cancer activity. But there is no report on the effect and mechanism of gerbeloid J on cycle and apoptosis of breast cancer. By using the CCK-8, clone formation, and PI staining assays, the effects of gerbeloid J on the proliferation of MCF-7 and MDA-MB-231 cells were assessed in this study. The effects of gerbeloid J on the apoptosis and mitochondrial function of MCF-7 and MDA-MB-231 cells were assessed using DAPI, Annexin V/TO-PRO-3, Rhod-2 AM, TMRM, DCFDA staining assays, and Western blot. The results demonstrated that gerbeloid J regulated the P21/CDC25C/CDK-1/cyclin B1 pathway and arrested the cell cycle at G2/M phase to suppressed the proliferation of MCF-7 and MDA-MB-231 cells. Additionally, gerbeloid J induced apoptosis through the stimulation of mitochondrial calcium excess, reduction of mitochondrial membrane potential, and promotion of ROS generation, and its mechanism was related to the activation of mitochondrial apoptotic pathway. In conclusion, by regulating the P21/CDC25C/CDK-1/cyclin B1 pathway and activating the mitochondrial apoptosis pathway, gerbeloid J could cause breast cancer cell cycle arrest and apoptosis, which might offer a promising candidate for the creation of new drugs against breast cancer.

Fermented Chinese medicine has long been used. Amid the advance for preservation of experience, the connotation of fermented Chinese medicine has been enriched and improved. However, fermented Chinese medicine prescriptions generally contain a lot of medicinals. The fermentation process is complicated and the conventional fermentation conditions fail to be strictly controlled. In addition, the judgment of the fermentation end point is highly subjective. As a result, quality of fermented Chinese medicine is of great difference among regions and unstable. At the moment, the quality standards of fermented Chinese medicine are generally outdated and different among regions, with simple quality control methods and lacking objective safe fermentation-specific evaluation indictors. It is difficult to comprehensively evaluate and control the quality of fermented medicine. These problems have aroused concern in the industry and also affected the clinical application of fermented Chinese medicine. This article summarized and analyzed the application, quality standards, and the modernization of fermentation technology and quality control methods of fermented Chinese medicine and proposed suggestions for improving the quality standards of the medicine, with a view to improving the overall quality of it.

Objectives: To investigate the role of donor change in the second hematopoietic stem cell transplantation (HSCT2) for hematological relapse of malignant hematology after the first transplantation (HSCT1) . Methods: We retrospectively analyzed patients with relapsed hematological malignancies who received HSCT2 at our single center between Mar 1998 and Dec 2020. A total of 70 patients were enrolled[49 males and 21 females; median age, 31.5 (3-61) yr]. Results: Forty-nine male and 21 female patients were enrolled in the trial. At the time of HSCT2, the median age was 31.5 (3-61) years old. Thirty-one patients were diagnosed with acute myeloid leukemia, 23 patients with ALL, and 16 patients with MDS or other malignant hematology disease. Thirty patients had HSCT2 with donor change, and 40 patients underwent HSCT2 without donor change. The median relapse time after HSCT1 was 245.5 (26-2 905) days. After HSCT2, 70 patients had neutrophil engraftment, and 62 (88.6%) had platelet engraftment. The cumulative incidence of platelet engraftment was (93.1±4.7) % in patients with donor change and (86.0±5.7) % in patients without donor change (P=0.636). The cumulative incidence of CMV infection in patients with and without donor change was (64.0±10.3) % and (37.0±7.8) % (P=0.053), respectively. The cumulative incidence of grade Ⅱ-Ⅳ acute graft versus host disease was (19.4±7.9) % vs (31.3±7.5) %, respectively (P=0.227). The cumulative incidence of TRM 100-day post HSCT2 was (9.2±5.1) % vs (6.7±4.6) % (P=0.648), and the cumulative incidence of chronic graft versus host disease at 1-yr post-HSCT2 was (36.7±11.4) % versus (65.6±9.1) % (P=0.031). With a median follow-up of 767 (271-4 936) days, 38 patients had complete remission (CR), and three patients had persistent disease. The CR rate was 92.7%. The cumulative incidences of overall survival (OS) and disease-free survival (DFS) 2 yr after HSCT2 were 25.8% and 23.7%, respectively. The cumulative incidence of relapse, OS, and DFS was (52.6±11.6) % vs (62.4±11.3) % (P=0.423), (28.3±8.6) % vs (23.8±7.5) % (P=0.643), and (28.3±8.6) % vs (22.3±7.7) % (P=0.787), respectively, in patients with changed donor compared with patients with the original donor. Relapses within 6 months post-HSCT1 and with persistent disease before HSCT2 were risk factors for OS, DFS, and CIR. Disease status before HSCT2 and early relapse (within 6 months post-HSCT1) was an independent risk factor for OS, DFS, and CIR post-HSCT2. Conclusion: Our findings indicate that changing donors did not affect the clinical outcome of HSCT2.

Objective: To investigate the distribution and characteristics of gene mutations in osteosarcoma, and to analyze the frequency and types of detectable mutations, and to identify potential targets for individualized treatment of osteosarcoma. Methods: The fresh tissue or paraffin-embedded tissue samples of 64 cases of osteosarcoma that were surgically resected or biopsied and then subject to next generation sequencing, were collected from Beijing Jishuitan Hospital, China from November 2018 to December 2021. The tumor DNA was extracted to detect the somatic and germline mutations using targeted sequencing technology. Results: Among the 64 patients, 41 were males and 23 were females. The patient age ranged from 6 to 65 years with a median age of 17 years, including 36 children (under 18 years old) and 28 adults. There were 52 cases of conventional osteosarcoma, 3 cases of telangiectatic osteosarcoma, 7 cases of secondary osteosarcoma, and 2 cases of parosteosarcoma. The detection rate of gene mutations was overall 84.4% (54/64). There were 324 variations in 180 mutated genes, including 125 genes with copy number variations, 109 single nucleotide variants, 83 insertions or deletions, and 7 gene fusions. The most common mutated genes were TP53, VEGFA, CCND3, ATRX, MYC, RB1, PTEN, GLI1, CDK4 and PTPRD. Among them, TP53 had the highest mutation rate (21/64, 32.8%), single nucleotide variant was the main mutation type (14/23, 60.9%), and 2 cases carried the TP53 germline mutation. VEGFA and CCND3 showed copy number amplification simultaneously in 7 cases. Conclusions: The high-frequency mutation of TP53 suggests that it plays an important role in the pathogenesis and development of osteosarcoma. VEGFA, CCND3 and ATRX are mutated genes in osteosarcoma and worthy of further studies. Combination of pathologic diagnosis and next generation sequencing with clinical practice can guide individualized treatment for patients with refractory, recurrent and metastatic osteosarcoma.
