OBJECTIVE To investigate the effects and potential mechanism of Qiangxin decoction on mitochondrion of rats with chronic heart failure (CHF). METHODS The CHF model was established by ligating the left anterior descending branch of the coronary artery. Modeled rats were divided into model group, Qiangxin decoction low-dose and high-dose groups (12.25, 24.50 g/kg, calculated by crude drug), and chemical medicine group (Sacubitril valsartan sodium tablets, 10.42 mg/kg), with 10 rats in each group; control group was set up without treatment. Each group of rats was orally administered with the corresponding medication or normal saline twice a day for 28 consecutive days. After the last medication, the contents of N-terminal pro-brain natriuretic peptide (NT-proBNP) and adenosine triphosphate (ATP) in serum and phosphatidic acid (PA) and cardiolipin (CL) in myocardial tissue were all detected; the pathological damage and collagen fibrosis of rat myocardial tissue were observed; the apoptosis of myocardial cells was determined; the ultrastructure of myocardial tissue was observed; the protein expressions of mitofusin 1 (Mfn1), Mfn2, optic atrophy protein 1 (OPA1) and dynamin-related protein 1 (Drp1) were all detected in myocardial tissue. RESULTS Compared with control group,the serum content of NT-proBNP, apoptotic rate of myocardial cells, and relative expressions of S-OPA1 and Drp1 proteins were all increased significantly; serum content of ATP,contents of PA and CL, and relative expressions of Mfn1, Mfn2 and L-OPA1 proteins were all significantly reduced (P<0.05). There were abnormal membrane tissue structure in various layers of myocardial tissue, degeneration and necrosis of myocardial cells, and severe fibrosis; the mitochondria were swollen, with reduced or absent cristae, and uneven matrix density. After intervention with Qiangxin decoction, the levels of the aforementioned quantitative indicators in serum and myocardial tissue of rats (excluding CL content in the Qiangxin decoction low- dose group) were significantly reversed (P<0.05); the pathological damage of myocardial tissue had significantly improved, fibrosis had significantly reduced, mitochondrial morphology tended to be normal, cristae had increased, and matrix density was uniform. CONCLUSIONS Qiangxin decoction can regulate myocardial mitochondrial function and structural integrity of CHF rats, thereby improving myocardial energy metabolism and antagonizing myocardial fibrosis, the mechanism of which may be associated with activating PA/Mfn/CL signaling pathway.

Bronchial asthma (asthma) is a complex inflammatory airway disease affecting approximately 100 million children worldwide, imposing a heavy burden on society and families. Studies have shown that the gut microbiota plays a significant role in the occurrence and development of childhood asthma. This paper reviews the research progress on the relationship between gut microbiota and childhood asthma. By elucidating the composition, function, and relationship with the host of gut microbiota, the impact of changes in its composition and function on the development of asthma is revealed. Furthermore, the potential value and application prospects of modulating gut microbiota as a new strategy for asthma treatment are discussed, providing a theoretical reference for in-depth research on the relationship between gut microbiota and the onset of childhood asthma and the development of new therapeutic approaches.

OBJECTIVE:
To investigate the clinical features, treatment and prognosis of extranodal NK/T-cell lymphoma, nasal type (ENKTL) with skin lesions as initial symptom.
METHODS:
The clinical data of 11 ENKTL patients with skin lesions as initial symptom were retrospectively analyzed from August 2016 to January 2023 in Wuhan First Hospital and Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology.
RESULTS:
Among the 11 patients, there were 6 males and 5 females, with a median age of 50(32-80) years. All patients had different forms of skin lesions as initial clinical symptom, including rash, ulcerative mass, painful skin nodules, infiltrating macula, etc. Most of the skin lesions were involved in the limbs and trunk but also appeared in the lower limbs alone. Five patients had hemophagocytic lymphohistiocytosis (HLH) at initial diagnosis, and 8 patients had B symptoms. All patients were diagnosed with advanced clinical staging (Lugano staging IV), and classified as high risk (PINK-E score ≥3). Immunohistochemical examination revealed that the positive rates of CD56 and EBER were both 100%, and the median Ki-67 index was 75%(50%-80%). Plasma EBV-DNA tests were all positive (≥5×102 copies/ml). Most of the induction chemotherapy regimens were combination chemotherapy (MESA, p-Gemox, SMILE) containing pegaspargase or L-asparaginase, or combined with PD-1 monoclonal immunotherapy, or HLH regimens (HLH-04 regimen, L-DEP). The median follow-up time and overall survival (OS) time were both 4.5(0.5-27) months. During the follow-up period, all 8 patients who did not receive autologous hematopoietic stem cell transplantation (ASCT) died, most of whom died of rapid disease progression. Three patients received ASCT, one died of central nervous system recurrence after transplantation, and two survived. The OS of three patients who underwent ASCT was 21, 27, and 19 months, and PFS was 11, 20, and 13 months, respectively. The plasma EBV-DNA copy number was monitored irregularly after transplantation, and the load of EBV was consistent with the changes of the disease.
CONCLUSIONS
Early clinical symptoms of ENKTL patients with skin lesions as initial symptom are more atypical, and early diagnosis is particularly difficult. The disease progresses rapidly and the prognosis is poor. There is still no uniform standard for the best treatment strategy. The survival of patients can be significantly prolonged by applying ASCT as soon as possible after complete remission obtained by high-dose induction chemotherapy.

Objective: To systematically evaluate the clinical efficacy and safety of Tonifying kidney and activating blood therapy for the treatment of diabetic mellitus erectile dysfunction. Methods: China National Knowledge Infrastructure(CNKI), Wanfang Data, VIP, Chinese Biomedical Database(CBM), PubMed, Cochrane Library, Embase and Web of Science were searched from inception until October 20th of 2024,for randomized controlled trials of Tonifying kidney and activating blood therapy for the treatment of diabetic erectile dysfunction. Literature screening, quality evaluation, and data extraction were carried out in accordance with relevant standards. The software of RevMan5.4 was used for the analysis of publication bias. And meta-analysis was conducted to assess the impact of this therapy on IIEF-5, total effective rate, adverse reactions. The evidence levels according to the analysis results were evaluated. Results: Totally 19 RCTs were included, involving 1 612 patients. The result of meta-analysis indicated that Tonifying kidney and activating blood therapy had advantages on the improvement of IIEF-5 scores (MD=3.59,95%CI[2.14,5.03],P<0.01),total effective rate (OR=4.30,95%CI[3.29,5.32],P<0.000 01). However, there was no statistically significant difference in the incidence of adverse reactions(OR=0.98,95%CI[0.48,2.01],P=0.96) between the two groups. Conclusions: Tonifying kidney and activating blood therapy can improve the clinical efficacy and IIEF-5 score for the patients with diabetic erectile dysfunction. But considering the limited quantity of included studies, more high-quality studies still be needed to validate the therapeutic effect.

OBJECTIVE:
To explore the efficacy and safety of Juan Bi Pill (JBP) in treatment of active rheumatoid arthritis (RA).
METHODS:
From February 2017 to May 2018, 115 participants from 4 centers were randomly divided into JBP group (57 cases) and placebo group (58 cases) in a 1:1 ratio using a random number table method. Participants received a dose of JBP (4 g, twice a day, orally) combined with methotrexate (MTX, 10 mg per week) or placebo (4 g, twice a day, orally) combined with MTX for 12 weeks. Participants were required with follow-up visits at 24 and 48 weeks, attending 7 assessment visits. Participants were undergo disease activity assessment 7 times (at baseline and 2, 4, 8, 12, 24, 48 weeks) and safety assessments 6 times (at baseline and 4, 8, 12, 24, 48 weeks). The primary endpoint was 28-joint Disease Activity Score (DAS28-ESR and DAS28-CRP). The secondary endpoints included American College of Rheumatology (ACR) criteria for 20% and 50% improvement (ACR20/50), Health Assessment Questionnaire Disability Index (HAQ-DI), clinical disease activity index (CDAI), visual analog scale (VAS), Short Form-36 (SF-36) score, Medial Outcomes Study (MOS) sleep scale score, serum erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), tender joint count, swollen joint count, and morning stiffness. The adverse reactions were observed during the treatment.
RESULTS:
After 12 weeks of treatment, DAS28-ESR and DAS28-CRP scores in both groups were lower than before treatment (both P<0.01), while the remission rate of DAS28-ESR and DAS28-CRP and low disease activity of JBP group were higher than those in the placebo group (both P<0.01). JBP demonstrated better efficacy on ACR20 and ACR50 compliance rate at 12 and 48 weeks comparing to placebo (all P<0.05). The CDAI and HAQ-DI score, pain VAS and global VAS change of RA patients and physicians, the serum ESR and CRP levels, and the number of tenderness and swelling joints were lower than before treatment at 4, 8, 12, 24, 48 weeks in both groups (P<0.05 or P<0.01), while the reduction of above indices in the JBP group was more obvious than those in the placebo group at 12 weeks (ESR and CRP, both P<0.05) or at 12 and 48 weeks (all P<0.01). There was no difference in adverse reactions between the 2 groups during treatment (P=0.75).
CONCLUSION
JBP combined with MTX could effectively reduce disease activity in patients with RA in active stage, reduce the symptoms of arthritis, and improve the quality of life, while ensuring safety, reliability, and fewer adverse effects. (Trial Registration: ClinicalTrials.gov, No. NCT02885597).

Objective:To establish normal reference value ranges for dynamic balance function parameters in healthy Chinese adults aged 20-69 years. Methods:A total of 100 healthy subjects were selected and evenly divided into five age groups: 20-29, 30-39, 40-49, 50-59, and 60-69 years, with equal gender distribution in each group. Balance function was assessed using the EquiTest system (NeuroCom), with following tests performed Sensory Organization Test (SOT), Motor Control Test (MCT), Adaptation Test (ADT), and Limits of Stability (LOS) test. All parameters were statistically analyzed and expressed as ±S. Results:The normal reference ranges for SOT, MCT, ADT, and LOS parameters were established for each age group. Multiple balance function parameters demonstrated a gradual decline with advancing age, with more pronounced deterioration observed after the age of 60. Specific findings included decreased vestibular ratio and reduced visual preference in SOT, as well as prolonged reaction time, impaired directional control, and reduced maximum excursion in the backward direction during LOS testing. Conclusion:This study is the first to establish age-specific reference ranges for dynamic balance function parameters in a healthy Chinese population aged 20-69 years, providing localized and objective criteria for the assessment of balance function and supporting clinical diagnosis of balance-related disorders in China.

Transarterial radioembolization (TARE) is a widely utilized therapeutic approach for hepatocellular carcinoma (HCC), however, the clinical implementation is constrained by the stringent preparation conditions of radioembolization agents. Herein, we incorporated the superstable homogeneous iodinated formulation technology (SHIFT), simultaneously utilizing an enhanced solvent form in a carbon dioxide supercritical fluid environment, to encapsulate radionuclides (such as 131I,177Lu, or 18F) with lipiodol for the preparation of radiolipiodol. The resulting radiolipiodol exhibited exceptional stability and ultra-high labeling efficiency (≥99%) and displayed notable intratumoral radionuclide retention and in vivo stability more than 2 weeks following locoregional injection in subcutaneous tumors in mice and orthotopic liver tumors in rats and rabbits. Given these encouraging findings, 18F was authorized as a radiotracer in radiolipiodol for clinical trials in HCC patients, and showed a favorable tumor accumulation, with a tumor-to-liver uptake ratio of ≥50 and minimal radionuclide leakage, confirming the feasibility of SHIFT for TARE applications. In the context of transforming from preclinical to clinical screening, the preparation of radiolipiodol by SHIFT represents an innovative physical strategy for radionuclide encapsulation. Hence, this work offers a reliable and efficient approach for TARE in HCC, showing considerable promise for clinical application (ChiCTR2400087731).

Peptide-drug conjugates (PDCs) have emerged as a promising modality in precision oncology, enabling targeted delivery of cytotoxic payloads while minimizing off-target toxicity. The integration of covalent warheads, such as those based on sulfur(VI) fluoride exchange (SuFEx) chemistry, enhances drug-target residence time and tumor accumulation. However, existing screening methods for covalent peptide (CP) libraries require post-translational warhead conjugation, limiting throughput. Here, we present an integrated mRNA display platform that incorporates covalent warheads during ribosomal synthesis, enabling efficient screening of ultra-diverse covalent macrocyclic peptide libraries (>1013 variants). This approach, using site-specific incorporation of N-chloroacetyl-d-phenylalanine and fluorosulfate-l-tyrosine, accelerated the discovery of irreversibly binding (K i = 3.58 μmol/L) Nectin-4-targeting peptide CP-N1-N3 via proximity-triggered SuFEx. The peptide was further conjugated to cytotoxic payloads, yielding the covalent PDC CP-N1-MMAE with potent cytotoxicity (IC50 ≈ 43 nmol/L) against MDA-MB-468 cells. This platform establishes a new paradigm for precision covalent drug discovery.
