OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors （DTIs） in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital （the Affiliated Hospital of UESTC）， a multidisciplinary working group was established. Through literature review and the Delphi method， clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework； systematic searches were conducted in CNKI， Medline， Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations （each with an expert consensus rate exceeding 90%） on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection， dosing ranges， key monitoring points， and safety management strategies for parenteral DTIs in various scenarios， including the perioperative period of ventricular assist device implantation， the perioperative period of cardiac surgery， perioperative patients with lower-extremity atherosclerotic disease， the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome， the perioperative period of carotid artery stenting in patients with carotid stenosis， the perioperative period of patients with right heart thrombosis， and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition， warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

Objective To explore the symptom prevalence in the patients with pulmonary nodules in Lingnan area and to investigate the influencing factors,thus to provide data support for the construction of differentiation and treatment system of symptoms-syndrome elements-syndromes-constitutions for patients with pulmonary nodules,and to promote the establishment of secondary prevention system of lung cancer with the in-depth participation of traditional Chinese medicine(TCM).Methods A cross-sectional study was adopted to investigate patients with pulmonary nodules who admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine from August 2023 to January 2024.Data collection covered the basic information,clinical characteristics and symptoms of the patients.Likert four-level scale was used for the grading of the severity of the symptoms,multivariate linear regression was adopted to construct three regression models,and then the factors influencing the severity of symptoms of patients with pulmonary nodules were explored.Results(1)A total of 274 patients were enrolled in the analysis,including 160 females and 114 males,with a mean age of(54.44±12.00)years old and the symptom scores averaging(3.97±3.80)point.The included patients with pulmonary nodules were characterized by females outnumbering males,a higher proportion of middle-aged and elderly people,multiple pulmonary nodules being more common.(2)The analysis of the symptoms of the 274 patients showed that symptoms with an incidence over 30%were fatigue(116 cases,42.34%),cough(105 cases,38.32%),expectoration of white sputum(89 cases,32.48%),and irritability and distress(87 cases,31.75%).(3)Multivariate linear regression analysis after variable adjustment suggested that the overall symptomatic severity in the male was milder than that in the female[β=-1.67,95%CI(-2.67,-0.68),P<0.001],and symptom score was positively correlated with age[β=0.07,95%CI(0.03,0.10),P<0.001],history of exposure to secondhand smoke[β=1.27,95%CI(0.26,2.27),P=0.015],history of exposure to other hazardous substances[β=1.96,95%CI(0.39,3.53),P=0.015],and history of allergy[β=2.38,95%CI(1.22,3.54),P<0.001]significantly.Conclusion The overall symptoms of patients with pulmonary nodules in Lingnan area are mild,and the high prevalence of symptoms are fatigue,cough,expectoration of white sputum,and irritability and distress.The symptom severity is correlated with gender,age,history of exposure to secondhand smoke,history of exposure to other hazardous substances,and history of allergy.

Originating in Huangdi Neijing,this theory was pioneered by ZHANG Zhongjing,who established the principles of concurrent heart-lung treatment and integrated therapeutic approaches.It further developed during the Ming-Qing period and has been widely applied in modern clinical practice.This article systematically traces the developmental trajectory of the heart-lung correlation theory in traditional Chinese medicine and analyzes its clinical application in elucidating the pathogenesis and therapeutic strategies for lung cancer complicated by cardiovascular comorbidities.According to this theoretical framework,lung cancer accompanied by cardiovascular comorbidities exhibits a pathomechanism characterized by fundamental deficiency with symptomatic excess.The deficiency manifests as qi-blood depletion or impaired descent of gathering qi,while the excess is reflected in phlegm-stasis coagulation or heat-toxin accumulation.Key pathological features include progressive transformation,meridian disharmony,deteriorating vital substances,and disruption of inter-organ relationships.Treatment adheres to the principles of concurrent heart-lung intervention,integrated cardiopulmonary modulation,and reciprocal organ regulation.Core therapeutic strategies involve eliminating pathogenic factors,promoting circulation,tonifying deficiencies,and harmonizing functions with specific interventions determined through pattern differentiation.For the pattern of phlegm and blood stasis coagulation affecting both the heart and lung,treatment is guided by the principle of simultaneous treatment of phlegm and stasis,coordinated regulation of heart-lung function,and prioritization of qi circulation.Commonly used formulas include Gualou Xiebai Banxia Decoction and Xuefu Zhuyu Decoction.In cases of heat toxin accumulation in the heart and lungs,therapy follows the principle of clearing heart-lung fire and dredging collaterals,often using combinations of insect-derived medicines and vine-derived herbs,such as earthworm and Chinese star jasmine stem.In instances of heart-lung qi-blood deficiency,the therapeutic approach emphasizes simultaneous fortification and qi and blood circulation.Formulas such as modified Renshen Yangrong Decoction or Shengxian Decoction,combined with Taohong Siwu Decoction,are commonly used.These formulas strengthen qi without stagnating blood,promote blood circulation without harming healthy qi,and gradually eliminate pathogens.These three treatment approaches embody the characteristics of integrated heart-lung therapy,emphasizing dynamic regulation and holistic concepts.The focus remains on addressing both manifestation and root causes through flexible herb selection to achieve optimal therapeutic outcomes.

Objective:To develop an artificial intelligence (AI)-based platelet review strategy to identify abnormal platelet histograms with no significant difference between initial impedance platelet count (PLT-I) and PLT-F results.Methods:This study included 5 119 routine blood analysis in Nanfang Hospital of Southern Medical University and its Ganzhou branch from July 2023 and March 2024. Specimens exhibiting abnormal platelet histograms and an initial platelet count >40×10?/L underwent review using the fluorescent platelet count (PLT-F) channel. Consistency of the results was defined as a difference between impedance platelet count (PLT-I) and PLT-F less than ±20% of the PLT-F results. A deep learning model was developed using platelet and red blood cell histogram data from a training set of 3 807 specimens. The model′s diagnostic performance was evaluated on an independent external validation set ( n=805) using receiver operating characteristic (ROC) curve analysis. Changes in the number of reviewed samples and sample turnaround time were analyzed to assess its clinical utility. Results:The deep learning model based on platelet and red blood cell histograms achieved an area under the ROC curve (AUC) of 0.854 in the training set. At a cutoff value of 0.1, the sensitivity was 0.954 and specificity was 0.358. The model could reduce review by 16.80% (190/1 131). In the validation set, the AUC was 0.805, with a sensitivity of 0.955 and specificity of 0.307, corresponding to a reduction of 17.41% (47/270) in reviewed specimens.Conclusion:The platelet review prediction model developed based on deep learning technology can efficiently identify samples with consistent results before and after review, reducing unnecessary reviews and shortening specimen testing time, thereby improving the efficiency of platelet test.

Based on the discussions in the The Inner Canon of Yellow Emperor （《黄帝内经》）， it is proposed that in the course of the disease， "bind" represents the initial stage of pulmonary nodules， while "accumulation" represents the final form. In terms of the pathogenesis， "two colds interacting" represented by "body cold" and "cold fluid retention" are the prerequisites for the formation of pulmonary nodules， while "disorder of qi" represented by "fainting" is the core of the formation. The specific manifestation is the disturbance of pivot of shaoyang （少阳） or shaoyin （少阴）， resulting in a complex of cold and heat， and then phlegm and stasis are suddenly generated and further formed into nodules. Therefore， the treatment principle should be to regulate the cardinal mechanism， dissolve phlegm and blood stasis. Depending on the complex degree of cold and heat， it is suggested to use Chaihu Guizhi Decoction （柴胡桂枝汤）， Chaihu Guizhi Ganjiang Decoction （柴胡桂枝干姜汤）， or Chaihu Xianxiong Decoction （柴胡陷胸汤） for disturbance of shaoyang pivot， while for shaoyin pivot dysfunction， modified Mahuang Fuzi Xixin Decoction （麻黄附子细辛汤） or Shengjiang Powder （升降散） can be used.

ObjectiveTo investigate the tumor inhibition effect and mechanism of Yifei Sanjie Pills （益肺散结丸， YSP） on lung cancer. MethodsLewis lung cancer tumor-derived mice were established and divided into four groups including model control group， cisplatin group， cisplatin + YSP low-dose group and cisplatin + YSP high-dose group， with 12 mice in each group. The corresponding interventions were given for 14 days. The tumor volume was measured on the 0th， 3rd， 7th， 10th and 14th days of administration to evaluate the tumor growth. The plasma and tumor tissue were collected on the 15th day. Plasma from the model group， the cisplatin group and the cisplatin+YSP high-dose group were selected， and plasma exosomes were extracted； the differences in miRNA expression among the groups were detected and analyzed by second-generation sequencing technology， and the potential mechanism of action of YSP was investigated by principal component analysis， biofunctional enrichment analysis and miRNA-target gene regulatory network analysis. Quantitative real-time PCR was used to detect the expression of miRNA-615-3p in tumor tissues， and the relationship between miRNA-615-3p and overall survival of lung cancer were analyzed using the Kaplan-Meier plotter （kmplot.com） database. ResultsCompared to that of the model control group， the tumor volume of the cisplatin group on day 10， and the cisplatin + YSP low- and high-dose groups on day 7， 10， and 14 were significantly reduced （P＜0.05 or P＜0.01）. Compared to that of the cisplatin group， the tumor volume of the cisplatin + YSP low- and high-dose groups on day 10 and 14 was significantly reduced （P＜0.05）. The principal component analysis of miRNA expression profiles showed significant differences in miRNA expression between different intervention groups. There were 21 differentially expressed miRNAs between the model control group and the cisplatin group， 50 differentially expressed miRNAs between the model control group and the cisplatin+ YSP high-dose group， and 6 differentially expressed miRNAs between the cisplatin group and the cisplatin+ YSP high-dose group. Biological function enrichment analysis showed that the differentially expressed miRNAs were mainly involved in the regulation of signaling pathways related to cell growth， proliferation， differentiation， autophagy and other biological activities. The miRNA-target gene regulatory network showed the top 20 genes that were targeted， among which there were proven miRNAs and genes related to lung cancer， and miRNAs that needed further investigation. The expression of miRNA-615-3p in tumor tissues decreased significantly in the cisplatin group and cisplatin+YSP high-dose group compared to that of the model group（P＜0.05 or P＜0.01）. The miRNA-615-3p was negatively correlated with the survival prognosis of lung cancer（P＜0.05）. ConclusionCisplatin combined with YSP can effectively inhibit the proliferation of Lewis lung cancer tumors， and the tumor-suppressive effect is related to the regulation of multiple miRNAs， especially the downregulation of miRNA-615-3p expression.
