The plants of the genus Caragana Fabr. are desert plants of the Leguminosae family, which are widely used in traditional ethnomedicine, with the effects of nourishing Yin and nourishing blood, dispelling wind and removing dampness, clearing heat and detoxifying toxins. The anti-inflammatory effect of Caragana Fabr. has attracted much attention, the research on the related mechanism has made some progress, but it lacks systematic collation. By summarising the anti-inflammatory effects of the active ingredients of Caragana Fabr., the authors found that they have good anti-inflammatory activities on different inflammatory cell models in vitro, and have good improvement effects on rheumatoid arthritis, colitis, complex nephritis, and acute lung injury and other disease models. The anti-inflammatory effects of the active components of this genus mainly include the reduction of the levels of a variety of pro-inflammatory factors, and the signalling pathways involved mainly include TLR4/NF-κB, TLR4/MAPK, TLR4/NF-κB/IRF3, JAK/STAT-1, ERK/STAT-1 and so on. Therefore, the paper mainly reviews the research progress on the anti-inflammatory effects and mechanisms of the Caragana Fabr. plants and their active components according to disease types, with a view to providing reference for the in-depth study of their anti-inflammatory activities and the development of new products with related functions.

Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

OBJECTIVES: To investigate the clinical features and prognosis of children with non-Down-syndrome-related acute megakaryoblastic leukemia (non-DS-AMKL). METHODS: A retrospective analysis was conducted on the medical data of 17 children with non-DS-AMKL who were admitted to Children's Hospital of The First Affiliated Hospital of Zhengzhou University from January 2013 to December 2023, and their clinical features, treatment, and prognosis were summarized. RESULTS: Among the 17 children with non-DS-AMKL, there were 8 boys and 9 girls. Fourteen patients had an onset age of less than 36 months, with a median age of 21 months (range:13-145 months). Immunophenotyping results showed that 16 children were positive for CD61 and 13 were positive for CD41. The karyotype analysis was performed on 16 children, with normal karyotype in 6 children and abnormal karyotype in 9 children, among whom 5 had complex karyotype and 1 had no mitotic figure. Detected fusion genes included EVI1, NUP98-KDM5A, KDM5A-MIS18BP1, C22orf34-BRD1, WT1, and MLL-AF9. Genetic alterations included TET2, D7S486 deletion (suggesting 7q-), CSF1R deletion, and PIM1. All 17 children received chemotherapy, among whom 16 (94%) achieved complete remission after one course of induction therapy, and 1 child underwent hematopoietic stem cell transplantation (HSCT) and remained alive and disease-free. Of all children, 7 experienced recurrence, among whom 1 child received HSCT and died of graft-versus-host disease. At the last follow-up, six patients remained alive and disease-free. CONCLUSIONS Non-DS-AMKL primarily occurs in children between 1 and 3 years of age. The patients with this disorder have a high incidence rate of chromosomal abnormalities, with complex karyotypes in most patients. Some patients harbor fusion genes or gene mutations. Although the initial remission rate is high, the long-term survival rate remains low.

OBJECTIVE: To explore the anti-photoaging properties of salvianolic acid B (Sal B). METHODS: The optimal photoaging model of human immortalized keratinocytes (HaCaT cells) were constructed by expose to ultraviolet B (UVB) radiation. The cells were divided into control, model and different concentrations of Sal B groups. Cell viability was measured via cell counting kit-8. Subsequently, the levels of oxidative stress, including reactive oxygen species (ROS), hydroxyproline (Hyp), catalase (CAT), and glutathione peroxidase (GSH-Px) were detected using the relevant kits. Silent information regulator 1 (SIRT1) protein level was detected using Western blot. The binding pattern of Sal B and SIRT1 was determined via molecular docking. RESULTS: Sal B significantly increased the viability of UVB-irradiated HaCaT cells (P<0.05 or P<0.01). Sal B effectively scavenged the accumulation of ROS induced by UVB (P<0.05 or P<0.01). In addition, Sal B modulated oxidative stress by increasing the intracellular concentrations of Hyp and CAT and the activity of GSH-Px (P<0.05 or P<0.01). The Western blot results revealed a substantial increase in SIRT1 protein levels following Sal B administration (P<0.05). Moreover, Sal B exhibited good binding affinity toward SIRT1, with a docking energy of -7.5 kCal/mol. CONCLUSION Sal B could improve the repair of photodamaged cells by alleviating cellular oxidative stress and regulating the expression of SIRT1 protein.

Objective:To explore the maintenance of sinus rhythm and the changes in functional tricuspid regurgitation(FTR) in patients with atrial fibrillation(AF) combined with FTR following the Mei Mini Maze Procedure, and to analyze the correlation between these two factors.Methods:We retrospectively included 180 patients with AF and FTR who underwent left-sided thoracoscopic AF ablation(the Mei Mini Maze Procedure) at Xinhua Hospital in Shanghai from January 2019 to December 2021. After propensity score matching to eliminate confounding factors, the patients were divided into two groups based on the severity of FTR before surgery: the non-significant FTR group(+ -+ +, 68 cases) and the significant FTR group(≥+ + +, 68 cases). Outpatient follow-up with 24-72 hour dynamic electrocardiogram and transthoracic echocardiography(TTE) was conducted at 3, 6, 12, 24, and 36 months post-discharge. The maintenance of sinus rhythm and changes in FTR were compared between the two groups.Results:All patients successfully completed the Mei Mini Maze Procedure. Compared to preoperative values, the severity of FTR improved in both groups. Non-significant FTR group: 59% of patients(40 cases) had no regurgitation, 27%(18 cases) had mild FTR, 11%(8 cases) had moderate FTR, and 3%(2 cases) had severe FTR; significant FTR group: 19%(n=13) had no regurgitation, 25%(17 cases) had mild FTR, 25%(17 cases) had moderate FTR, and 31%(21 cases) had severe FTR. The Kaplan-Meier(KM) curve revealed that the sinus rhythm maintenance rate at 3 years post-surgery was significantly higher in the non-significant FTR group(72.06%) than in the significant FTR group (57.35%), with a statistically significant difference( P=0.011). Multivariate analysis showed that postoperative FTR ≥ moderate( HR=11.469), preoperative significant FTR( HR=1.206), age over 65 years( HR=3.734), non-paroxysmal AF( HR=2.346), and longer AF duration( HR=1.151) were risk factors for AF recurrence in this cohort. Conclusion:The recovery of sinus rhythm in AF patients is closely related to the severity of FTR. Patients with preoperative significant FTR had a lower rate of sinus rhythm maintenance after surgery. Both preoperative and postoperative significant FTR are risk factors for AF recurrence in AF patients with FTR. Therefore, for patients with significant FTR, simultaneous treatment of FTR during the surgery, including a standard Cox-Maze Ⅳ procedure, may be more beneficial for maintaining postoperative sinus rhythm.

The ocean plays a critical role in the global carbon cycle,and base on the"dual carbon"goals,ocean carbon sinks have received widespread attention.Shellfish aquaculture is one of the most important sources of carbon sinks in fisheries,which has an important impact on the offshore carbon cy-cle.As global temperature rises and ocean acidification intensifies,the capacity of the ocean to absorb CO2 will change.However,the effects of high temperature on the physiology and transcriptome related to carbon metabolism in Mytilus coruscus are not clear enough.This study investigated the effects of high temperatures on the total carbon content,carbon metabolism,antioxidant-related enzyme activities,and the transcriptome of Mytilus coruscus.The results showed that high temperature significantly inhibited the activities of hexokinase and pyruvate kinase,increased carbonic anhydrase activity(P＜0.05),de-creased the ATP content of digestive glands(P＜0.05),and affected glycolysis and the tricarboxylic acid cycle,leading to a significant decrease in the mussel's ability to sequester carbon.High temperature re-sulted in significant(P＜0.05)increases in the levels of reactive oxygen species and malondialdehyde,and enhanced the activities of superoxide dismutase and catalase.Observations by transmission electron microscopy showed that high temperatures damaged the subcellular structure of the digestive gland in Mytilus coruscus,resulting in the shrinkage of the nucleolus,swelling of the endoplasmic reticulum,and a significant reduction in the mitochondrial cristae.Comparative transcriptomic analysis showed that the upregulated DEGs were mainly enriched in protein processing in the endoplasmic reticulum,antigen pro-cessing and presentation,and MAPK signaling pathway.The downregulated DEGs were mainly enriched in necroptosis,DNA replication,and the NF-kappa B signaling pathway.In antioxidant-related DEGs,the upregulated DEGs include vitamin K epoxide reductase,peroxidases,heat shock protein 105 kD,heat shock protein 70 kD,and superoxide dismutase;The downregulated DEGs mainly included NADPH oxidase,glutathione reductase,cytochrome b-245,cytochrome P450,and quinone reductase.The up-regulated genes enriched in the carbon metabolism pathway included chitinase,phosphatidylinositol 4,5-bisphosphate 3-kinase,phosphoenolpyruvate carboxykinase,galactokinase,and inositol trisphosphate 3-kinase.The downregulated genes included aldose-1-epimerase,carbonic anhydrase,galactose mutaro-tase,acyl-CoA synthetase,alcohol dehydrogenase,and hexokinase.In conclusion,high temperature has an inhibitory effect on the activities of enzymes and the expression of genes related to carbon metabolism in Mytilus coruscus.The results of this study are intended to provide a scientific basis for the healthy de-velopment of mussel aquaculture and the assessment of carbon sinks.

Objective:To investigate the current status of the implementation of home-based phototherapy (HBPT) in patients with vitiligo, and to analyze management needs among patients receiving HBPT.Methods:A questionnaire survey was conducted on the application of HBPT among patients with vitiligo who visited the outpatient clinic of the Hospital for Skin Diseases, Chinese Academy of Medical Sciences from December 2021 to November 2022. Additionally, the popularization and usage of HBPT as well as needs of patient management were investigated and analyzed in these vitiligo patients.Results:A total of 496 valid questionnaires were collected from 496 patients with vitiligo (241 males [48.5%] and 255 females [51.5%]) . Their ages at visit ranged from 2 to 67 (30.87 ± 12.36) years. The most commonly affected sites were the head and face (52.2%) , followed by hair (32.1%) , hands and feet (31.4%) , trunk (30.2%) , limbs (24.3%) , neck (19.5%) , and perineum (9.9%) . Among the participants, 320 (64.5%) were currently using or had used HBPT, and 352 (70.8%) expressed a willingness to learn more about HBPT usage guidelines and health education. Regarding the repigmentation outcomes after HBPT: among 312 patients, 54 (17.3%) reported complete recovery, 64 (20.5%) were markedly improved, 142 (45.5%) experienced improvement, and 52 (16.7%) showed no response. Adverse reactions occurred in 223 patients (71.5%) , of whom 28 (9.0%) experienced severe adverse reactions. The most desired guiding information was the adjustment method for phototherapy dosage and treatment duration (184/352, 52.3%) ; the most effective way to receive health education information was through verbal education by medical staff (177/352, 50.3%) .Conclusion:For vitiligo patients who were willing to accept and use HBPT, the most desired guiding information was the adjustment method for phototherapy dosage and treatment duration, and verbal health education by medical staff appeared to be the main way to obtain health education information.

Treatment-resistant depression (TRD) remains a major challenge in psychiatric clinical practice. However, there is still substantial controversy in the academic community regarding how to define and assess it, and treat and manage these patients effectively. This paper reviews the evolution of the concept of "treatment resistance"in depression with a particular focus on comparing the conventional concept of TRD with the recently proposed concept of "Difficult-to-Treat Depression (DTD)". It explores the underlying rationale and logic behind this conceptual shift, and discusses the practical challenges associated with implementing the "DTD" framework in clinical practice. Finally, the paper provides targeted recommendations to address these challenges, aiming to serve as a reference for psychiatric clinicians and researchers in China.

Anticipatory anxiety is a negative emotion that arises when individuals encounter potential threats or uncertainties in the future. It is the core symptom of a variety of anxiety disorders, and is closely associated with the occurrence, severity, treatment outcome, and prognosis of anxiety disorders, which has garnered a growing amount of focus in clinical practice. Nevertheless, scientific research on anticipatory anxiety continues to face obstacles such as unclear pathological mechanisms, the absence of simple and consistent self-assessment tools, and effective interventions. To improve understanding of the role of anticipatory anxiety in the diagnosis and treatment of anxiety disorders, this study reviews pertinent domestic and international literature, and briefly introduces the concept, assessment and measurement, activation paradigm, pathological mechanisms, and interventions of anticipatory anxiety.
