Objective To analyze the proportion and clinicopathological characteristics of HER2-positive breast cancer patients with BRCA1/2 pathogenic variants, and their response to neoadjuvant anti-HER2 targeted therapy. Methods The clinicopathological data of 531 breast cancer patients with germline BRCA1/2 pathogenic variants (201 with BRCA1 variants and 330 with BRCA2 variants) were analyzed. Results Among the 201 BRCA1 and 330 BRCA2 variants, 17 (8.5%) and 42 (12.7%) HER2-positive breast cancer cases were identified, respectively, accounting for 11.1% of all BRCA1/2-mutated breast cancers. Compared with BRCA1/2-mutated HR-positive/HER2-negative patients, HER2-positive patients did not present any significant differences in clinicopathological features; however, compared with triple-negative breast cancer patients, HER2-positive patients had a later onset age and lower tumor grade. Among the 17 patients who received neoadjuvant anti-HER2 targeted therapy, 10 cases achieved pCR (58.8%), whereas 7 cases did not (41.2%). Conclusion HER2-positive breast cancer accounts for more than 10% of BRCA1/2-mutated patients. Approximately 40% of these patients fail to achieve pCR after neoadjuvant targeted therapy. This phenomenon highlights the possibility of combining anti-HER2 targeted agents with poly (adenosine diphosphate-ribose) polymerase inhibitors.

ObjectiveTo observe the intervention effect of Huaiqihuang granules （HQH） on immunoglobulin A vasculitis nephritis （IgAVN） mice and explore the underlying therapeutic mechanism. MethodFifty SPF-grade male Kunming mice were randomly divided into a normal group， an IgAVN model group， a dexamethasone group （2.5 mg·kg^-1·d^-1）， a low-dose HQH group （4 g·kg^-1·d^-1）， and a high-dose HQH group （8 g·kg^-1·d^-1）. The mouse model was established using oral administration of gliadin combined with intravenous injection of India ink. After successful modeling， the mice were euthanized after 4 weeks of gastric gavage according to groups. The 24 h urinary total protein （24 h UTP）， urine β₂-microglobulin （β₂-MG）， serum total protein， albumin， IgA， etc. were detected in each group. Flow cytometry was used to determine the proportion of T helper 17 （Th17） cells in spleen cell suspension. Western blot was employed to detect the expression of adenosine 5'-monophosphate-activated protein kinase α （AMPKα）， phosphorylated AMPKα （p-AMPKα）， acetyl-CoA carboxylase 1 （ACC1）， and phosphorylated ACC1 （p-ACC1） in Th17 cells. Pathological changes in the spleen and kidneys were observed. ResultCompared with the normal group， the IgAVN model group showed significant increases in 24 h UTP， urine β₂-MG， total cholesterol （P<0.05）， serum interleukin-17 （IL-17）， IgA， Th17 proportion in the spleen cell suspension， and IL-17 expression in the spleen tissue （P<0.01）， and significantly decreased serum total protein， albumin， p-AMPKα/AMPKα， and p-ACC1/ACC1 expression of Th17 cells （P<0.01）. Compared with the IgAVN model group， in the 4th week， the 24 h UTP， urine β₂-MG， serum IL-17， IgA levels， and renal IgA deposition were significantly reduced in each treatment group （P<0.01）， and the Th17 proportion and IL-17 expression in spleen tissue were significantly decreased （P<0.05， P<0.01）. Serum albumin levels significantly increased （P<0.05）. Compared with the IgAVN model group， the dexamethasone group and the high-dose HQH group showed increases in serum total protein （P<0.01）， p-AMPKα/AMPKα， and p-ACC1/ACC1 expression of Th17 cells （P<0.05， P<0.01）. The high-dose HQH group showed a significant decrease in total cholesterol level （P<0.05）. Various treatment groups showed different degrees of improvement in spleen and kidney pathological changes. ConclusionHQH may affect Th17 cell differentiation by regulating the AMPK/ACC pathway， correcting immune inflammatory disorders， and exerting therapeutic effects on IgAVN.

Objective:To investigate the clinical efficacy and safety of ZR2 (zevalin + lenalidomide + rituximab) regimen in the treatment of elderly patients with diffuse large B-cell lymphoma (DLBCL).Methods:A retrospective case series study was conducted. The clinical data of 16 elderly (>65 years old) non-germinal center B-cell-like DLBCL patients treated with ZR2 regimen at the Taixing People's Hospital from January 2021 to March 2023 were retrospectively analyzed. The efficacy, adverse reactions and prognosis of patients were observed.Results:Of the 16 patients, 11 were male and 5 were female, with the age [ M ( Q1, Q3)] of 76 years old (70 years old, 78 years old), and 10 cases were Ann Arbor stage Ⅲ-Ⅳ. Among the 16 patients, 9 achieved complete remission, 4 patients achieved partial remission. All 16 patients experienced varying degrees of reversible bone marrow suppression, grade Ⅲ-Ⅳ hematologic adverse reactions included neutropenia (7 cases) and thrombocytopenia (2 cases), and the bone marrow hematopoiesis recovered after treatment with granulocyte colony-stimulating factor and thrombopoietin. The main ≥grade Ⅱ non-hematologic adverse reactions were gastrointestinal reactions (5 cases), liver function abnormalities (3 cases) and peripheral neuropathy (2 cases), which were improved after the appropriate treatment. Two patients discontinued the treatment of this regimen due to disease progression, and 1 patient died from complications after 2 cycles of treatment. No deep vein thrombosis, cardiac toxicity or renal toxicity occurred during the treatment process. Conclusions:The ZR2 regimen is effective in the treatment of elderly DLBCL patients with tolerable adverse reactions.

Objective:To analyze the genetic evolution characteristics of hemagglutinin (HA) and neuraminidase (NA) of influenza B virus in Tongling during 2019-2022 surveillance years.Methods:Twenty-two strains of Victoria influenza B virus isolated from our laboratory during 2019-2022 were selected for whole genome sequencing. The sequence comparison and phylogenetic analysis were conducted by using bioinformatic analysis software.Results:During 2019-2022, seasonal influenza in Tongling City was predominantly caused by influenza B Victoria lineage viruses, which fell within the V1A.3 branch. Among these, 14 strains isolated in the 2021-2022 season were further classified into the V1A.3a.2 sub-branch. Compared with vaccine strains, multiple amino acid mutation sites were detected in both HA and NA proteins of the 22 influenza B Victoria lineage viruses. Notably, all four major antigenic sites (120-loop, 150-loop, 160-helix, and 190-helix regions) in the HA protein exhibited variations. Although no mutations were detected at resistance sites on the NA protein, a change occurred in the glycosylation site at position 197 NETQ in the HA protein.Conclusions:The main amino acid sites of the HA protein of the influenza B Victoria lineage viruses in Tongling City from 2019 to 2022 have undergone significant variation, which may lead to antigenic drift. Therefore, it is essential to strengthen the monitoring of influenza virus mutations.

Objective The current article aimed to explore the previous focuses,highlight the latest progresses and analyze the future trends on the research of medicinal Pteridophyes.Methods 794 scientific names and 414 Chinese names of medical used ferns and lycopods were established as search term from five public documentary libraries(i.e.,Web of Science,PubMed,CNKI,WangFang and Cqvip),respectively.After data cleaning,5465 publications in English and 8918 publications in Chinese were refined as effective datasets.Subsequently,the up-to-date bibliometric methods and visualization software packages were employed to fulfill the graphical bibliometric analyses.Results The yearly publication numbers in both English and Chinese showed fluctuating upward patterns,and each of them has undergone three phases with distinct rates of rise(i.e.,embryonic stage,smoothly-rising stage and sharply-rising stage).Significant national and territorial discrepancies exist in the various types of literature.The topics in English literature on medicinal Pteridophyes mainly included ontogenetic process and phylogeny,plant-environment interactions,and the pharmacological activities of various metabolites(e.g.alkaloids).The Chinese literature is not only concerned with individual development and pharmacological effects,but also focuses on the application of new technologies,emphasizes the application of them in traditional Chinese medicine and traditional Chinese and Western medicine.Moreover,our results pointed out rising hotspot medicinal Pteridophyes species such as Drynaria roosii and Huperzia serrata.Conclusion Our present study implied that the medicinal Pteridophyes have aroused wide attention in domestic and foreign scholar and will be continuous concerned for a long time in the future.Currently,4 different aspects(i.e.,phytoremediation,phylogenetic analysis,pharmacological activity and clinical application)are the main research focal points towards this clade of medical plant species,and it is an important emerging tendency that we should apply the multi-omics technology to investigate the Pteridophyes species and unravel their medical values.

Objective:To analyze the effects of low-dose methimazole treatment on thyroid volume and calcitonin levels in patients with hyperthyroidism.Methods:A total of 100 hyperthyroidism patients who were treated at the Mianyang Central Hospital from January to June 2019 were selected and randomly divided into a control group (50 cases) and an observation group (50 cases) using a random number table method. The control group was treated with once a day and 30 mg/dose of methimazole, while the observation group was treated with twice a day and 10 mg/dose of methimazole. Thyroid volume, and thyroid function [Thyroid growth hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone receptor antibody (TRAb)] before and after treatment in two groups of patients, the changes in serum levels of calcitonin (CT), visfatin, tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were compared. The clinical efficacy of two groups were also compared.Results:The total clinical effective rate of the observation group was higher than that of the control group ( P<0.05). After treatment, the thyroid volume in the observation group was significantly smaller than that in the control group, and the CT level was significantly lower than that in the control group (all P<0.05). After treatment, the TSH level in the observation group was significantly higher than that in the control group, while the levels of FT3, FT4, and TRAb were significantly lower than those in the control group (all P<0.05). After treatment, the levels of Visfatin, TNF-α, and IL-6 in the observation group were significantly lower than those in the control group (all P<0.05). Conclusions:Low dose methimazole can improve thyroid function, reduce thyroid volume, lower body CT and inflammation levels in patients with hyperthyroidism, and has a better therapeutic effect.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
