Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Patients with panvascular disease (PVD) often experience bleeding events while receiving standard antithrombotic therapy. Based on the theory of "guarding the channel passages", the retention of blood stasis is considered as a crucial pathological basis for PVD. The combination of the retention of blood stasis and the failure of the channel passages to contain blood constitutes the core pathogenesis of bleeding events in this condition. According to their pathogenesis and clinical characteristics, bleeding events in PVD are categorized into a bleeding stage and a stable stage. During the bleeding stage, treatment should focus on stanching bleeding and dispersing stasis to restore normal circulation in the channel passages. During the stable stage, treatment should aim to dispel stasis and generate new blood to harmonize the channel passages. In clinical practice, physicians should dynamically weigh the risks of bleeding and ischemia against the intensity of antithrombotic therapy. The ultimate goal is to harmonize qi and blood and ensure that blood remains properly contained within the channel passages, thereby reducing the risk of bleeding events and enhancing overall patient benefit.

Objective To reveal the scientific output and trends in pulmonary nodules/early-stage lung cancer prediction models. Methods Publications on predictive models of pulmonary nodules/early lung cancer between January 1, 2002 and June 3, 2023 were retrieved and extracted from CNKI, Wanfang, VIP and Web of Science database. CiteSpace 6.1.R3 and VOSviewer 1.6.18 were used to analyze the hotspots and theme trends. Results A marked increase in the number of publications related to pulmonary nodules/early-stage lung cancer prediction models was observed. A total of 12581 authors from 2711 institutions in 64 countries/regions published 2139 documents in 566 academic journals in English. A total of 282 articles from 1256 authors were published in 176 journals in Chinese. The Chinese and English journals which published the most pulmonary nodules/early-stage lung cancer prediction model-related papers were Journal of Clinical Radiology and Frontiers in Oncology, respectively. Chest was the most frequently cited journal. China and the United States were the leading countries in the field of pulmonary nodules/early-stage lung cancer prediction models. The institutions represented by Fudan University had significant academic influence in the field. Analysis of keywords revealed that multi-omics, nomogram, machine learning and artificial intelligence were the current focus of research. Conclusion Over the last two decades, research on risk-prediction models for pulmonary nodules/early-stage lung cancer has attracted increasing attention. Prognosis, machine learning, artificial intelligence, nomogram, and multi-omics technologies are both current hotspots and future trends in this field. In the future, in-depth explorations using different omics should increase the sensitivity and accuracy of pulmonary nodules/early-stage lung cancer prediction models. More high-quality future studies should be conducted to validate the efficacy and safety of pulmonary nodules/early-stage lung cancer prediction models further and reduce the global burden of lung cancer.

[Objective] To systematically evaluate the therapeutic effect of washed red blood cells and white suspended red blood cells on patients with autoimmune hemolytic anemia, and to provide reference for their clinical treatment. [Methods] CNKI, Wanfang, VIP, PubMed, Embase, Cochrane Library and other databases from the establishment of the database to August 2024 were searched, including the randomized controlled trials of washed red blood cells and white suspended red blood cells in the treatment of autoimmune hemolytic anemia that met the requirements. After literature screening, data extraction and quality evaluation, meta-analysis was performed using Review manager 5.3 software and Stata 15.1 software to analyze the therapeutic effect of blood transfusion in the primary outcome, hematological indicators (Hb, Ret, RBC, and TBIL) of the two groups after blood transfusion and the occurrence of adverse blood transfusion reactions. [Results] After screening, 10 literatures meeting the criteria were retrieved, and a total of 753 patients with autoimmune hemolytic anemia were treated with washed red blood cell infusion in the observation group and white suspended red blood cell infusion in the control group. Meta-analysis suggested that there was no significant difference in the therapeutic effect of transfusion between patients who received washed red cells and those received white suspended red cells[SMD=1.16, 95%CI (0.87, 1.54), P>0.05]. The hematological indexes of the two groups after transfusion (Hb [SMD=0.04, 95%CI (-0.14, 0.22), P>0.05]、Ret[SMD=-0.15, 95%CI (-0.34, 0.03), P>0.05]、RBC[SMD=0.08, 95%CI (-0.10, 0.26), P>0.05] and TBIL [SMD=-0.02, 95%CI (-0.18, 0.15), P>0.05]) and the incidence of transfusion adverse reactions[SMD=0.8, 95%CI (0.47, 1.39), P>0.05] were not significantly different. [Conclusion] Based on the current study, the efficacy and safety of infusion of washed red blood cells and white suspended red blood cells are comparable in patients with autoimmune hemolytic anemia. However, considering the simple preparation process of washed red blood cells and the low price, infusion of washed red blood cells is recommended for patients with autoimmune hemolytic anemia.

Traditional Chinese medicine (TCM) offers a rich theoretical foundation and clinical experience for the prevention and treatment of cardiovascular-kidney-metabolic syndrome(CKM), demonstrating unique advantage. Building on previous work in managing diabetes, its complications, and chronic kidney disease, our team has proposed a five-phase evolution theory of "constraint, heat, deficiency, stasis, and toxin" as the core pathogenesis. These phases correspond to the pathological progression of constraint of phlegm-dampness, constraint transforming into heat, heat damaging qi and yin, stasis accumulated in the collateral vessels, and toxin induced by deficiency and stasis. In the prevention and treatment of CKM by TCM, it is emphasized to integrate the concept of "treating disease before it arises" with constitution theory, and incorporate the "2-5-8" prevention and treatment strategy, which combines prevention with treatment, tailors interventions to different phases, and employs comprehensive treatment modalities. Our goal is to leverage TCM's holistic advantages in preventing and treating CKM.

ObjectiveTo evaluate the efficacy of Shexiang Baoxinwan in treating stable angina pectoris with Qi stagnation and blood stasis syndrome in patients with coronary artery disease (CAD) complicated with anxiety and depression and explore its underlying mechanisms. MethodsThis study employed a randomized, double-blind, and placebo-controlled clinical trial design. Patients admitted to the hospital were randomly assigned to the observation group and the control group, with 52 patients in each group. Patients in the observation and control groups received Shexiang Baoxinwan and placebo, respectively, both in combination with conventional Western medication. The dose was 45.0 mg, three times daily, for a total duration of eight weeks. The primary outcome was the Seattle Angina Questionnaire (SAQ) scores before and after treatment. Secondary outcomes included changes in traditional Chinese medicine (TCM) syndrome score, the patient health questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7), inflammatory markers [interleukin-18 (IL-18), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), CD40, etc.], monoamine neurotransmitters [e.g., dopamine (DA)], vascular endothelial function markers [e.g., endothelin-1(ET-1)], adipokines, and ischemia-modified albumin (IMA). Adverse reactions were also recorded. ResultsA total of 92 patients completed the study, with 44 in the observation group and 48 in the control group. Compared with baseline, both groups showed significant decreases in PHQ-9, GAD-7, and TCM syndrome scores following treatment (P<0.05), along with a significant increase in SAQ scores (P<0.05). In the observation group, DA levels were significantly increased (P<0.05), while levels of IL-18, TNF-α, CD40, ET-1, and IMA were decreased (P<0.05). In contrast, the control group exhibited significantly increased CD40 levels (P<0.05). Compared with the control group after treatment, the observation group showed significant improvements in the SAQ dimensions of physical limitation, angina stability, treatment satisfaction, and disease perception, as well as in TCM syndrome score, PHQ-9 score, IL-18, CD40, ET-1, and IMA (P<0.05). No adverse reactions were observed in either group during treatment. ConclusionShexiang Baoxinwan can improve anxiety and depression, alleviate angina symptoms, and reduce TCM symptoms of Qi stagnation and blood stasis in CAD patients. The mechanism may involve anti-inflammation, improvement of vascular endothelial function, reduction of IMA, and increase of monoamine neurotransmitter levels.
