The analysis presented here is based on the blood components of Guanxin Qiwei tablets, the key anti-atherosclerosis pathway of Guanxin Qiwei tablets was screened by network pharmacology, and the anti-atherosclerosis mechanism of Guanxin Qiwei tablets was clarified and verified by cell experiments. HPLC-Q-Exactive-MS/MS technique was used to analyze the components of Guanxin Qiwei tablets into blood, to determine the precise mass charge ratio of the compounds, and to conduct a comprehensive analysis of the components by using secondary mass spectrometry fragments and literature comparison. Finally, a total of 42 components of Guanxin Qiwei tablets into blood were identified. To better understand the interactions, we employed the Swiss Target Prediction database to predict the associated targets. Atherosclerosis (AS) disease targets were searched in disease databases Genecard, OMIM and Disgent, and 181 intersection targets of disease targets and component targets were obtained by Venny 2.1.0 software. Protein interactions were analyzed by String database. The 32 core targets were selected by Cytscape software. Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed in DAVID database. It was found that the anti-atherosclerosis pathways of Guanxin Qiwei tablets mainly include lipid metabolism and atherosclerosis and AGE-RAGE signaling pathway in diabetic complications and other signal pathways. The core targets and the core compounds were interlinked, and it was found that cryptotanshinone and tanshinone ⅡA in Guanxin Qiwei tablets were well bound to TNF, PPARγ, AKT1, PTG2 and other targets. The lipid metabolism and atherosclerotic pathway was verified using human hl-7702 hepatocytes. This study preliminarily identified the potential pharmacodynamic components of Guanxin Qiwei tablets in the treatment of AS diseases and predicted their pathways of action, and verified the relationship between regulating lipid metabolism and atherosclerosis of Guanxin Qiwei tablets in vitro, providing a reference for the further study of the pharmacodynamic material basis and mechanism of action of this prescription. This experiment was approved by the Medical Ethics Committee of Inner Mongolia Medical University (No. YKD202401262).

Objective To explore the characteristics of myocardial injury in patients with acute myocardial infarction(AMI)complicated by pleural effusion and its effect on long-term prognosis.Methods It was a prospective single-center study.Patients with AMI who were admitted to hospital within 15 days from symptom onset and performed echocardiography and cardiac magnetic resonance imaging(CMR)during hospitalization were consecutively enrolled and assigned to the with-pleural effusion group and the without-pleural effusion group according to the echocardiography result.Baseline data,cardiac magnetic resonance myocardial injury index and echocardiography characteristics were compared between the two groups.The occurrence of major adverse cardiovascular and cerebrovascular events(MACCE)was recorded through outpatient follow-up and telephone follow-up,including all-cause death,re-infarction,revascularization,rehospitalization for congestive heart failure and stroke.Cox regression analysis was performed to analyze influencing factors of all-cause death.Results Among 211 patients,31(14.7%)patients had pleural effusion and 180(85.3%)had no pleural effusion.Compared with the group without pleural effusion,the left ventricular end-diastolic diameter was larger,and left ventricular ejection fraction assessed by echocardiography was lower in the group with pleural effusion(P＜0.05).There were no significant differences in infarct size,left ventricular end-diastolic volume,left ventricular end-systolic volume,left ventricular ejection fraction and the presence of microvascular obstruction and intramyocardial hemorrhage between the two groups in CMR(all P＞0.05).At a median follow-up of 31 months,MACCE occurred in 43(20.4%)patients,and there was no significant difference between the two groups(χ2=3.160,P=0.075).Six cases(2.8%)had all-cause death.The incidence of all-cause death was higher in the group with pleural effusion than that in the group without pleural effusion(9.7%vs.1.7%,P<0.05).There was no significant difference in the incidence of other adverse events between the two groups(P＞0.05).Multivariate Cox regression analysis showed that advanced age and presence of pleural effusion were independent risk factors of all-cause death during follow-up.Conclusion Patients with AMI combined with pleural effusion have more severe myocardial injury and higher all-cause mortality.

Gallbladder carcinoma,a relatively rare malignancy within the biliary tract,presents a grave prognosis primarily due to asymptomatic early stages leading to advanced stage diagnosis and the absence of efficacious treatment options.Research has identified chronic inflammation,predom-inantly caused by gallstones,as a critical etiological factor.While surgical intervention offers potential curative outcomes in early stages,the majority of cases are identified too late for optimal surgical outcomes.Chemotherapy and targeted therapy,despite offering new therapeutic avenues,have not significantly improved overall survival rates.Thus,understanding the pathogenesis of gallbladder cancer,especially its association with key genetic and molecular pathways,is imperative for devising novel therapeutic strategies.This review delineates the epidemiology,pathogenesis,current treat-ment modalities,and research advancements in gallbladder cancer,aiming to provide innovative in-sights for clinical management and guide future research endeavors.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective:To explore the clinical effect of a modified surgical procedure for replantation of severed digit-tips in Tamai zones I-II.Methods:From November 2019 to October 2022, the Department of Hand and Foot Microsurgery of the First Affiliated Hospital of Bengbu Medical College employed a modified procedure (to abandon the anatomically labelling of blood vessels and nerves after naked-eye debridement and fracture fixation, then perform the microscopic dissections and anastomoses of blood vessels and nerves, and the anastomosis of dorsal veins though an auxiliary small incision by the lateral nail fold of the severed digit-tip) to replant severed digit-tips in Tamai zones I-II of 26 patients (29 digits). The patients were 20 males (23 digits) and 6 females (6 digits), aged 3-66 years old, with mean age at 28 years old. Nineteen digit-tips were severed in Tamai zone I and 10 in Tamai zone II. The severed digit-tips were 7 of thumbs, 9 of index fingers, 5 of middle fingers, 5 of ring fingers and 3 of little fingers. Causes of injury were 12 of cut, 8 of crush and 6 of avulsion. Postoperative management included infection prevention, antispasmodic for 3 days and keeping in bed for 5 days. The time of surgery was recorded on all patients. Postoperative follow-ups were conducted at outpatient clinics for 6 to 12 months to observe the survival of digit-tips and the appearance, recovery of sensation and motor functions, strength of digits and patient satisfaction.Results:(1)The surgical time was about 1.0 hour for replantation of a severed digit-tip in Tamai zone I, while it took about 1.5 hours for those in Tamai zone II. (2)Survival rate and appearance: all 29 replanted digit-tips survived, except 2 in Tamai zone I which encountered venous occlusion and survived after small incision for bloodletting. Twenty-two digit-tips gained pulp fat pads with full digit pulps. Four avulsed digit-tips had mild atrophy of pulp. The 15 digit-tips severed in Tamai zone I were about 2 mm shorter than the healthy sides, but without deformity. One digit-tip had poor nail appearance due to preoperative fungal infection of nail bed. (3)Sensory recovery: with the British Medical Research Council (BMRC), 23 digit-tips recovered to S 3+, and 2 digit-tips of avulsion and 1 digit-tip of crush recovered to S 3. TPD of the replanted digit-tips were: 4-7 mm in those of cut injury; 6-8 mm in those of crush and 9-11 mm in those of avulsion. (4)Motion and digit strength: results of functional assessment according to the total active mobility standard promoted by China's Society for Surgery of the Hand were: 21 cases of excellent and 5 of good, without pain in digit pulp when pinching and griping. The mobility of the digits with replanted digit-tips of both Tamai zones I and II were close to that of the healthy sides. The motions of the digits with replanted digit-tips in Tamai zone I were close to the healthy sides and the 5 of those in Tamai zone II had 0° in extension and 2°-3° in flexion, due to the severed plane at distal interphalangeal joint. (5)Patient satisfaction: 25 patients were satisfied, however 1 patient was dissatisfied to the poor function of the distal interphalangeal joint due to the severed thumb-tip in Tamai zone II. Conclusion:Modified replantation procedure for severed digit-tip in Tamai zones I-II has significant achievement in cutting down the surgical time through a modified procedure of debridement and fracture fixation (tendon suture) by naked-eyes operation first, followed by dissections and anastomoses of the blood vessels and nerves under the surgical microscope. The auxiliary small incision by the lateral nail fold of digit-tip in Tamai zone I facilitates an exposure of a constant, healthy lateral nail fold vein. It enables the anastomosis with a high-quality vein, hence improves the success rate of replantation. The appearance and function of the replanted digit-tip are found better in the severed digit-tips of cut injury than those with injuries of avulsion and crush.

Objective:To explore and stimulate the pathway mechanism for doctors from core hospitals,which are the high-quality medical resources in loose medical alliances,to sink to the grassroots level on their own initiative and continue to participate in the co-operation,so as to provide useful references for improving the effectiveness of cooperation within medical alliances.Methods:The fuzzy set Qualitative Comparative Analysis(fsQCA)method was used to investigate 205 doctors in the core hospitals of a loose medical alliance in District X of City B.This investigation was grounded in relationship commitment theory,motivation theory,social exchange theory,and cooperation reinforcement theory.Results:The level of relationship commitment of doctors in the core hospitals to proactively participate in cooperation was influenced by multiple factors,including doctors'perception of job significance,opportunity cost perception,organizational support,and teamwork experience.This resulted in the formation of three concurrent driving mechanism pathways:merger-driven effect,experience-enhancing effect,and altruistic trigger effect.Among these factors,the perception of work significance was a necessary condition,and cooperative experience played an important role in doctors'continuous participation.Conclusion:The level of relational commitment of doctors to participate in cooperative efforts is driven by a combination of various factors,with different incentive mechanisms exhibiting heterogeneity within loose medical alliances.Designing appropriate incentive and support strategies tailored to specific contexts can effectively drive the proactive downward flow of high-quality medical resources from core hospitals within loose medical alliances.

Objective:To investigate the effect of integrin αvβ6 on lipid metabolism in colon cancer cells;to identify potential metabolic biomarkers for the diagnosis of colon cancer.Meth-ods:Liquid chromatography-mass spectrometry(LC-MS)-based lipidomic analysis was utilized to investigate the effects of αvβ6 on the changes in SW480 metabolism in colon cancer cell lines.The partial least squares discriminant analysis model showed different lipid profiles in Integrin αvβ6 over-expressed or low-expressed SW480.Results:After Integrin αvβ6 overexpression,a total of 252 lipids showed significant differences in SW480 cells,of which 138 showed up-regulation and 114 showed down-regulation.Moreover,the Methyl phosphatidylcholine(MePC),phosphatidyl-choline(PC),phosphatidylethanolamine(PE)and triglycerides(TG)were also found to have good diagnostic potential in αvβ6 overexpressing cancer cells.Conclusion:Integrin αvβ6 may promote cancer cell invasivness and metastasis by regulating pathways of dysregulated lipid metabolism.These results may provide potential clues to the molecular mechanisms of Integrin αvβ6 on colon cancer cells.

Objective To compare the efficacy and safety of transabdominal preperitoneal hernia repair (TAPP) and open tension-free inguinal hernia repair (Lichtenstein technique) for inguinal hernia after liver and kidney transplantation. Methods A retrospective analysis was conducted on data of 17 patients with inguinal hernia after liver and kidney transplantation. According to the surgical methods, 14 patients with TAPP were assigned to experimental group 1, and 20 patients without a history of organ transplantation during the same period were assigned to control group 1. Additionally, 3 patients with the Lichtenstein technique were assigned to experimental group 2, and 10 patients without a history of organ transplantation during the same period were assigned to control group 2. Statistical analysis was performed to compare operation time, blood loss, and postoperative recovery, and to analyze the impacts of different organ transplantation on surgical method selection. Results The operation time in experimental group 1 was (50.17±14.52) minutes, which was significantly longer than (33.77±10.19) minutes in the control group 1 (P < 0.05). No significant differences were observed between the two groups in terms of blood loss, postoperative ambulation time, and hospital discharge time (P>0.05). In experimental group 2, the operation time was (41.87±12.55) minutes and the blood loss was (10.78±7.56) mL, which was significantly longer than (27.14±10.64) minutes and higher than (5.40±1.56) mL in control group 2 (P < 0.05). There were significant differences in surgical blood loss and hospital discharge time between experimental group 1 and experimental group 2 (P < 0.05). Conclusion TAPP can improve surgical outcomes and safety, and reduce occurrence of complications. For patients with inguinal hernia after kidney transplantation combined with ureteral transplantation, the Lichtenstein technique is safer.

ObjectiveTo explore the efficacy-driving mechanism of Danhong injection （DHI） in the treatment of stable angina pectoris （SAP） based on the composition-activity relationship of target modules and clarify the pharmacological effects of DHI. MethodAccording to the angina frequency （AF） in the Seattle Angina Questionnaire （SAQ） that was obtained in the previous clinical trial， the patients before and after DHI treatment were grouped based on efficacy. The transcriptomic data of the patients before treatment and in the best efficacy group 30 days post-treatment were selected as the data source， and then weighted gene co-expression network analysis （WGCNA） was employed to construct the co-expression network. Relevant modules in the network were identified and associated with clinical features. In addition， the On-modules （Z value below 0） were identified by Zsummary. The topological indicators such as density， centrality， and clustering coefficient were adopted to explore the dynamics of DHI efficacy at the network level and module level， respectively. In addition， the driver genes were screened by the personalized network control （PNC） algorithm. Finally， rat H9C2 cells were used to establish the model of hypoxia/reoxygenation （H/R）， which was used to confirm the potential therapeutic target of DHI for SAP and provide a scientific basis for revealing the therapeutic mechanism of DHI. ResultWe identified 19 modules in the best efficacy group of DHI for SAP， and the comparison between day 0 and day 30 revealed 12 On-modules. The changes of network topological indicators at the network and module levels confirmed the correlation between the best efficacy of DHI treatment and topological dynamics. Finally， the driver genes， Klotho and fibroblast growth factor 22 （FGF22）， in DHI treatment of SAP were verified by the H9C2 cell model of H/R. ConclusionBased on clinical transcriptome data， this study determined the composition-activity relationship of target modules of DHI for SAP， which provided a scientific basis for deciphering the efficacy-driven mechanism of DHI for SAP.
