This study aims to explore the protective effect of Chaihu Jia Longgu Muli Decoction on rats with heart failure after myocardial infarction, and to clarify its possible mechanisms, providing a new basis for basic research on the mechanism of classic Chinese medicinal formula-mediated inflammatory response in preventing and treating heart failure induced by apoptosis after myocardial infarction. A heart failure model after myocardial infarction was established in rats by coronary artery ligation. The rats were divided into sham group, model group, and low, medium, and high-dose groups of Chaihu Jia Longgu Muli Decoction, with 10 rats in each group. The low-dose, medium-dose, and high-dose groups of Chaihu Jia Longgu Muli Decoction were given 6.3, 12.6, and 25.2 g·kg~(-1) doses by gavage, respectively. The sham group and model group were given an equal volume of distilled water by gavage once daily for four consecutive weeks. Cardiac function was assessed using color Doppler echocardiography. Myocardial pathology was detected by hematoxylin-eosin(HE) staining, apoptosis was measured by TUNEL assay, and mitophagy was observed by transmission electron microscopy. The levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-1β, and N-terminal pro-B-type natriuretic peptide(NT-proBNP) in serum were detected by enzyme-linked immunosorbent assay(ELISA). The expression of apoptosis-related proteins B-cell lymphoma 2(Bcl-2), Bcl-2-associated X protein(Bax), and cleaved caspase-3 was detected by Western blot. Additionally, the expression of phosphorylated nuclear transcription factor-κB(NF-κB) p65(p-NF-κB p65)(upstream) and nuclear factor kappa B inhibitor alpha(IκBα)(downstream) in the NF-κB signaling pathway was assessed by Western blot. The results showed that compared with the sham group, left ventricular ejection fraction(LVEF) and left ventricular short axis shortening(LVFS) in the model group were significantly reduced, while left ventricular end diastolic diameter(LVEDD) and left ventricular end systolic diameter(LVESD) increased significantly. Myocardial tissue damage was severe, with widened intercellular spaces and disorganized cell arrangement. The apoptosis rate was increased, and mitochondria were enlarged with increased vacuoles. Levels of TNF-α, IL-1β, and NT-proBNP were elevated, indicating an obvious inflammatory response. The expression of pro-apoptotic factors Bax and cleaved caspase-3 increased, while the anti-apoptotic factor Bcl-2 decreased. The expression of p-NF-κB p65 was upregulated, and the expression of IκBα was downregulated. In contrast, the Chaihu Jia Longgu Muli Decoction groups showed significantly improved of LVEF, LVFS and decreased LVEDD, LVESD compared to the model group. Myocardial tissue damage was alleviated, and intercellular spaces were reduced. The apoptosis rate decreased, mitochondrial volume decreased, and the levels of TNF-α, IL-1β, and NT-proBNP were lower. The expression of pro-apoptotic factors Bax and cleaved caspase-3 decreased, while the expression of the anti-apoptotic factor Bcl-2 increased. Additionally, the expression of p-NF-κB p65 decreased, while IκBα expression increased. In summary, this experimental study shows that Chaihu Jia Longgu Muli Decoction can reduce the inflammatory response and apoptosis rate in rats with heart failure after myocardial infarction, which may be related to the regulation of the IκBα/NF-κB signaling pathway.

Objective: Patients with advanced sarcomas have a dismal prognosis with few effective therapies. The purpose of this study was to evaluate the efficacy and safety of anlotinib in the treatment of advanced sarcoma and to explore the relationship between adverse events (AEs) and efficacy. Methods: Data from 45 advanced sarcoma patients who received anlotinib monotherapy at Affiliated Cancer Hospital of Zhengzhou University between June 2018 and August 2021 were retrospectively analyzed. According to Response Evaluation Criteria In Solid Tumors (RECIST) Version 1.1, the objective remission rate (ORR) and disease control rate (DCR) were calculated, and the progression free survival (PFS) and treatment-related AEs were recorded and analyzed. Survival analysis was conducted using the Kaplan-Meier survival rates were compared using the Log rank test. Results: Forty patients were treated for more than 1.5 months and received efficacy evaluation. The ORR and DCR after 3 months were 7.5%(3/40) and 80.0%(32/40), respectively. The overall ORR was 2.5%(1/40), the total DCR was 27.5%(11/40), and the median progression-free survival (m-PFS) was 6.70 months; The m-PFS of alveolar soft tissue sarcoma (ASPS) was 10.27 months, which was significantly longer than that of other subtypes of sarcoma (P=0.048). In addition, the DCR of ASPS and synovial sarcoma (SS) was significantly better than that of osteosarcoma (P<0.05). The most common AEs were elevated thyroid stimulating hormone (17.8%, 8/45), anemia (15.6%, 7/45), fatigue (11.1%, 5/45). Five patients developed grade 3 AEs after treatment; The PFS of patients with hand-foot syndrome after treatment was significantly longer than that of patients without hand-foot syndrome (14.10 vs 6.00, P=0.024). Conclusions: The efficacy of anlotinib in the treatment of ASPS and SS is better than that of other subtypes. The PFS in the group with hand-foot syndrome was significantly longer than that of the group without hand-foot syndrome.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Objective:To investigate the malignant potential of histopathological class B3 and B5a lesions by ultrasound-guided core needle biopsy (CNB).Methods:Retrospective analysis of the histopathological results of 712 breast lesions that successively underwent CNB process and surgical resection in the Shanghai General Hospital from January 2018 to December 2022, of which 47 lesions were reported as class B3 and 70 lesions as class B5a.Results:CNB identified 47 category B3 lesions, comprising 19 cases of atypical ductal hyperplasia, 17 papillary lesions, 8 phyllodes tumors, and 3 complex sclerosing lesions. Of these cases, surgical pathology was in full agreement with CNB pathology in 27 instances, indicating a concordance rate of 57.4% (27/47) and an inconsistency rate of 42.6% (20/47). Out of the 20 inconsistent cases, 70.0% (14/20) were upgraded based on the findings from the surgical pathology.Specifically, 4 cases of atypical ductal hyperplasia and 2 cases of intraductal papilloma were upgraded to invasive breast cancer (B5b) after surgery. Among the 4 cases with puncture pathology indicating atypical ductal hyperplasia and one complex sclerosing lesion, these five lesions were upgraded to ductal carcinoma in situ (B5a) after surgery. Two puncture pathologies were diagnosed as atypical ductal hyperplasia, and these were upgraded to ductal carcinoma in situ with microinvasion (B5b) after surgery. One puncture pathology indicated a borderline phyllodes tumor, and this was upgraded to malignant phyllodes tumor (B5b) after surgery. And 30.0% (6/20) resulted in downgrade after surgery, specifically 4 cases of atypical ductal hyperplasia, which were downgraded to breast adenopathy (B2). Of these, 1 puncture pathology was identified as atypical ductal hyperplasia and one as a borderline phyllodes tumor, which were both downgraded to fibroadenoma (B2). Seventy lesions were diagnosed as B5a lesions by CNB pathology, with 28 of them showing complete concurrence with the surgical pathology, a concordance rate of 40.0% (28/70), and an inconsistency rate of 60.0% (42/70). Of the 42 cases with discrepancies, all 42 were upgraded, yielding an upgrading rate of 100% (42/42). Of these, 21 were upgraded to ductal carcinoma in situ with microinvasion (B5b) and 21 to invasive breast cancer (B5b).Conclusions:Lesions with CNB pathology in categories B3 and B5a have a high rate of postoperative escalation. B3 and B5a lesions should be treated with considerable care, especially atypical ductal hyperplasia, which should be surgically resected, and CNB examination should be performed twice if necessary.
