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).

Green prescription is a written prescription aimed at improving health by promoting physical activity and improving diet， with advantages such as high cost-effectiveness， strong feasibility， and minimal harm to patients. The theory of traditional Chinese medicine （TCM） green prescription integrates the health philosophy of "following rule of yin and yang， and adjusting ways to cultivating health"， the exercise philosophy of balancing yin-yang and the five elements， and the dietary philosophy of moderation and balance， which embody core TCM concepts such as treating disease before its onset and harmony between humans and nature. It has also developed traditional exercise practices like Tai Chi， Baduanjin， Wuqinxi， Yi-Gin-Ching， and Qigong， as well as dietary adjustments like medicated diet and herbal wines. However， it is believed that the TCM green prescription currently suffers from insufficient evidence-based research， low patient awareness and acceptance， and weak basic research. Based on this， it is proposed that large-sample clinical trials should be conducted in the future to improve the quality of evidence-based medicine， basic research can be carried out with the help of artificial intelligence and other methods in research design， the hospital information system （HIS） can be used for control at the implementation level， and publicity and patient education can be strengthened through the new media， so as to promote the development and application of the TCM green prescriptions in the field of global health treatment.

Paclitaxel (PTX), a valuable natural product derived from Taxus species, exhibits remarkable anti-cancer properties. It penetrates nanopores in microtubule walls, interacting with tubulin on the lumen surface and disrupting microtubule dynamics, thereby inducing cytotoxic effects in cancer cells. PTX and its derivatives have gained approval for treating various diseases due to their low toxicity, high efficiency, and broad-spectrum application. The widespread success and expanding applications of PTX have led to increased demand, raising concerns about accessibility. Consequently, researchers globally have focused on developing alternative production methods and applying nanocarriers in PTX delivery systems to enhance bioavailability. This review examines the challenges and advancements in PTX sourcing, production, physicochemical properties, anti-cancer mechanisms, clinical applications, trials, and chemo-immunotherapy. It aims to provide a comprehensive reference for the rational development and effective utilization of PTX.

To analyze the changes in lactate dehydrogenase, creatine kinase, creatine kinase isoenzyme, high-sensitivity troponin T, N-terminal B-type natriuretic peptide precursor, homocysteine, and novel inflammatory indices (neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, systemic immune-inflammation index) before and after competitions in amateur marathon runners, and to assess the effects of myocardial injury due to acute exercise and the value of novel inflammatory indices in marathon exercise monitoring. This paper is an analytical study. Amateur athletes recruited by Beijing Hospital to participate in the 2022 Beijing Marathon and the 2023 Tianjin Marathon, and those who underwent health checkups at the Beijing Hospital Medical Checkup Center from January to June 2023 were selected as the study subjects, and 65 amateur marathon runners (41 males and 24 females) and 130 healthy controls (82 males and 48 females) were enrolled in the study according to the inclusion criteria. Peripheral blood was collected one week before, immediately after, and one week after running, and routine blood tests, cardiac enzymes, infarction markers, N-terminal B-type natriuretic peptide precursor, and homocysteine were performed to calculate the values of novel inflammatory indexes. Wilcoxon signed-rank test and Spearman′s rank correlation analysis were used to compare the differences in the levels of each index between the amateur marathon population and the health checkup population, and to compare the changes and correlations of each index at the three time points in the amateur marathoners.The results showed that the neutrophil-lymphocyte ratios of the healthy physical examination population and 65 amateur marathoners 1 week before running were 1.73 (1.33, 2.16) and 1.67 (1.21, 2.16), the platelet-lymphocyte ratios were 122.75 (96.69, 155.89) and 120.86 (100.74, 154.63), and the systemic immune inflammation index was 398.62 (274.50, 538.69) and 338.41 (258.62, 485.38), etc.; on 1 week before running, immediately after running and 1 week after running, lactate dehydrogenase of 65 amateur marathon runners was 173.00(159.00, 196.50)U/L,284.00(237.50, 310.50)U/L, 183.00(165.50, 206.50)U/L, creatine kinase was 131.00(94.30, 188.20)U/L,318.00(212.00, 573.15)U/L,139.00(90.55, 202.40)U/L, creatine kinase isoenzyme was 2.50(1.76, 3.43)μg/L,6.24(4.87, 10.30)μg/L,2.73(1.57, 4.40)μg/L.In 65 amateur marathon runners, lactate dehydrogenase, creatine kinase, creatine kinase isoenzyme, high sensitivity troponin T, N-terminal B-type natriuretic peptide precursor, homocysteine, and novel inflammation markers were significantly elevated in the immediate post-run period compared with 1 week before the run, and the differences were statistically significant ( Z=-7.009, Z=-6.813, Z=-6.885, Z=-7.009, Z=-7.009, Z=-6.656; P<0.05 for the above indicators).Neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and systemic immune-inflammatory index all showed significant positive correlation with the pre-and post-run rates of change of high-sensitivity troponin T ( ρ=0.28, P=0.03; ρ=0.31, P=0.01; ρ=0.27, P=0.03); these 3 markers were also significantly and positively correlated with the pre-and post-run rates of change in a collection of myocardial-related markers such as lactate dehydrogenase, creatine kinase, creatine kinase isozymes, high-sensitivity troponin T, N-terminal B-type natriuretic peptide precursor, and homocysteine, respectively( r=0.446, P=0.039; r=0.452, P=0.033; r=0.449, P=0.036).In addition, the platelet-lymphocyte ratio was positively correlated with the pre-and post-run rates of change in creatine kinase and creatine kinase isoenzymes( ρ=0.27, P=0.03; ρ=0.28, P=0.02).In conclusion, acute myocardial injury may be triggered during marathon exercise. Changes in novel inflammatory markers were significantly associated with changes in myocardial enzymes, infarction markers, N-terminal B-type natriuretic peptide precursors, and homocysteine, which may be of value for the prediction of myocardial injury during exercise.

Hyaluronan and proteoglycan link protein 1(Hapln1)supports active cardiomyogenesis in zebrafish hearts,but its regulation in mammal cardiomyocytes is unclear.This study aimed to explore the potential regulation of Hapln1 in the dedifferentiation and proliferation of cardiomyocytes and its therapeutic value in myocardial infarction with human induced pluripotent stem cell(hiPSC)-derived car-diomyocytes(CMs)and an adult mouse model of myocardial infarction.HiPSC-CMs and adult mice with myocardial infarction were used as in vitro and in vivo models,respectively.Previous single-cell RNA sequencing data were retrieved for bioinformatic exploration.The results showed that recombinant human Hapln1(rhHapln1)promotes the proliferation of hiPSC-CMs in a dose-dependent manner.As a physical binding protein of Hapln1,versican interacted with Nodal growth differentiation factor(NODAL)and growth differentiation factor 11(GDF11).GDF11,but not NODAL,was expressed by hiPSC-CMs.GDF11 expression was unaffected by rhHapln1 treatment.However,this molecule was required for rhHapln1-mediated activation of the transforming growth factor(TGF)-β/Drosophila mothers against decapentaplegic protein(SMAD)2/3 signaling in hiPSC-CMs,which stimulates cell dedifferentiation and proliferation.Recombinant mouse Hapln1(rmHapln1)could induce cardiac regeneration in the adult mouse model of myocardial infarction.In addition,rmHapln1 induced hiPSC-CM proliferation.In conclusion,Hapln1 can stimulate the dedifferentiation and proliferation of iPSC-derived cardiomyocytes by promoting versican-based GDF11 trapping and subsequent activation of the TGF-β/SMAD2/3 signaling pathway.Hapln1 might be an effective hiPSC-CM dedifferentiation and proliferation agent and a po-tential reagent for repairing damaged hearts.

Objective To investigate the social support needs of medical staff in Guangzhou during the post-COVID-19 period,providing a basis for relevant departments to offer targeted social support for medical staff in Guangzhou and improve their of occupational quality of life.Methods A cross-sectional survey was conducted,employing a combination of quota and conven-ience sampling to select subjects,eligible medical staff were invited to complete an online questionnaire.Results The social sup-port with a total score of 20 for medical staff in Guangzhou scored 9(7,11).Among the dimensions of social support,media sup-port scored the lowest.Social support as a whole scored with statistically significant differences across groups of different age,ed-ucational background,and job position(all P＜0.05).The median score was the lowest for those under 25 years,for those with a college degree or below,and highest among administrative staff,with other positions showing equal median score.The five di-mensions of social support ranked on the top concerning the total number of the respondents included patients'understanding and trust for medical staff(93.03％),increasing in salaries and benefits(86.06％),accurate policy promotion and public opinion guidance by media(83.41％),attention to the living conditions of medical staff by media(80.29％),and enhanced regulation of false reporting and inappropriate commentary by media(76.92％).Medical staff under the age of 25 had a high need for pa-tients'following doctor's advice,and medical staff with a collegiate degree or below had a high need for family members or friends to care about their physical and mental health.The five strongest needs for social support ranked on the top concerning the total number of respondents included understanding and trust from patients(75.72％),increased salaries and benefits(53.85％),assistance with household matters by family or friends(42.55％),correct policy promotion and public opinion guidance by media(34.62％),and attention to the living conditions of medical staff from media(33.41％).Conclusion Social support for medical staff in Guangzhou are at a relatively low level,indicating a need for social support from all levels of society.

Objective:To assess the effect of mild intraventricular hemorrhage（IVH）on the early motor development of infants at high risk of brain injury,and to guide the intervention according to its characteristics.Methods:A retrospective cohort study was conducted to select neonates discharged from the Neonatal Unit of Xi 'an Children 's Hospital from February 1，2022 to March 31，2023，with one or more high-risk factors of brain injury.The patients were assigned to low-grade IVH group and no IVH group according to ultrasound diagnosis.The research subjects exclucled other brain injury diseases besides mild IVH.Motor development was assessed using test of infant motor performance(TIMP)，reflecting performance in head control，auditory and visual responses，defensive movements，trunk movements，limb movements，and more.Both groups completed TIMP assessment between discharge and 16 weeks of the corrected age(CA).The differences of TIMP scores between two groups were compared . Results:A total of 329 neonates at high risk for brain injury were recruited，including 98 cases with grade Ⅰ-Ⅱ IVH（low-grade IVH group）diagnosed through brain ultrasonography and 231 controls(no IVH group).The Z scores of TIMP in the low-grade IVH group were lower than that in no IVH group（-0.25 ±0.87 vs.0.03 ±0.71， P=0.015）.The risk factors of brain injury were matched for further comparison.At CA2-5 weeks，the scores in low-grade IVH group of TIMP total scores（74.10 ±12.28 vs.84.24 ±7.71），observation items（10.57 ±1.47 vs.11.24 ±1.29），elicitation（63.17 ±12.13 vs.73.00 ±7.36），sitting（9.14 ±2.90 vs.11.65 ±3.26），supine（22.07 ±4.73 vs.24.79 ±3.55），prone position（10.35 ±3.74 vs.12.82 ±3.15）and lateral position（4.00 ±2.85 vs.5.48 ±2.13）were significantly lower than those in no IVH group（ P<0.05）.At CA6-9 weeks，the scores in low-grade IVH group of sitting position（10.44 ±4.01 vs.12.96 ±3.02），supine position（24.04 ±4.60 vs.26.83 ±3.53），lateral position（4.83 ±2.53 vs.6.25 ±2.6）were significantly lower than those in no IVH group（ P<0.05）.At CA12-15 weeks，the low-grade IVH group showed significant differences in TIMP total score（104.00 ±12.98 vs.114.10 ±13.16），elicitation（92.00 ±12.64 vs.102.00 ±13.10），sitting（17.00 ±3.50 vs.19.13 ±3.55）and lateral position（7.35 ±2.14 vs.9.00 ±2.37）compared with those from no IVH group（ P<0.05）. Conclusion:Mild intraventricular hemorrhage affected the early motor development of high-risk infants with brain injury，mainly manifested as a lag in the ability of head control at CA2-5 weeks，and the trend continued until CA12-15 weeks.Early monitoring of motor ability and intervention of head control ability should be carried out in high-risk children with mild intraventricular hemorrhage.

Objective To explore the value of peripheral blood circulating DNA in predicting the efficacy and prognosis of immunotherapy for advanced non-small cell lung cancer.Method A retrospective study was conducted on 78 NSCLC patients who were admitted to the Respiratory and Critical Care Medicine Department of the First Affiliated Hospital of Hebei North University and were treated with tirelizumab for advanced driver gene negativity from January 2021 to December 2021.After 2 cycles of immunotherapy,the efficacy was evaluated according to the Solid Tumor Efficacy Evaluation Criteria(RECIST 1.1),including complete remission,partial remission,disease stability,and disease progression.CR and PR patients were defined as the experimental group(n=48)Other patients were defined as the control group(n=30),and the ctDNA levels in peripheral blood were measured before and after treatment in both groups.ROC curves were used to analyze the predictive value of periph-eral blood ctDNA levels for achieving objective remission after immunotherapy.All patients were followed up and their progression free survival were calcutated.Using univariate and multivariate regression analysis identified the factors affecting the prognosis of patients after immunotherapy.Using Spearman correlation coefficient analyzed the correlation between ctDNA levels and PFS.Kalplan Meier survival curve were used for survival analysis.Result The peripheral blood ctDNA levels before and after treatment in the experimental group were(4.47±1.21)ng/μL and(2.65±1.14)ng/μL,respectively(t=7.559,P<0.001),while those in the control group were(4.54±1.15)ng/mL and(4.29±1.57)ng/μL,respectively(t=0.699,P=0.487).There was no statistically significant difference in peripheral blood ctDNA levels between the two groups before treatment(t=-0.25,P=0.801).The peripheral blood ctDNA levels in the experimental group decreased compared to the control group after treatment(t=-5.35,P<0.001).The ROC curve analysis showed that the area under the curve for predicting objective remission after immunotherapy based on peripheral blood ctDNA levels was 0.819,with a sensitivity of 81.3%and specificity of 80%.Peripheral blood ctDNA levels were negatively correlated with progression free survival(r=-0.784,P=0.000).Single factor COX regression was used to analyze the clinical and pathological characteristics and ctDNA levels of enrolled patients,and the results showed that the maximum tumor diameter was greater than 5 cm(HR=0.501,95%CI:6.731～35.567)Tumor stage IV(HR=0.392,95%CI:0.227～0.677),treatment approach(HR=15.473,95%CI:6.731～35.567),and ctDNA levels(HR=4.657,95%CI:3.182～6.555)are all influencing factors for PFS in advanced NSCLC patients after immunotherapy.Multiple factor analysis was conducted on the appeal indicators with statistical differences,and the results showed that treatment approach(HR=2.981,95%CI:1.019～8.722)and peripheral blood ctDNA levels(HR=3.918,95%CI:2.619～5.861)It is an independent influencing factor of PFS in advanced NSCLC patients.The Kalplan Meier survival curve was used for analysis,and the results showed that the median PFS of the treatment effective group was 8.4 months,while the median PFS of the control group was 5.4 months.(χ2=49.277,P=0.000).Conclusion Immunotherapy combined with chemotherapy can enhance the ability to kill tumor cells,and peripheral blood ctDNA levels can evaluate the efficacy and prognosis of immunotherapy,which can be used to guide immunotherapy in advanced NSCLC patients.

Objective:To explore the prognostic value of epidermal growth factor receptor (EGFR) co-mutation status in patients with advanced lung adenocarcinoma.Methods:Clinical data of patients with stage ⅢB-Ⅳ lung adenocarcinoma who were first diagnosed in the Department of Respiratory and Critical Care Medicine, First Affiliated Hospital of Hebei North University from January 2019 to December 2022 were collected prospectively. Patients were divided into EGFR mutation group ( n=82) and EGFR co-mutation group ( n=74) according to whether EGFR was combined with other gene mutations. The level of circulating tumor DNA (ctDNA) in peripheral blood was measured by real time fluorescence quantitative PCR. Objective response rate (ORR), disease control rate (DCR), the levels of ctDNA in peripheral blood, and progression-free survival (PFS) were compared between two groups of patients before and after 1 month of treatment. The univariate and multivariate analyses were conducted by Cox proportional hazards regression model. Results:In the EGFR mutation group, there were 45 cases of EGFR19 deletion mutation and 37 cases of EGFR21 mutation. In the EGFR co-mutation group, there were 41 cases of EGFR19 deletion mutation, 33 cases of EGFR21 mutation, 46 cases of TP53 mutation, 16 cases of RB1 mutation, 6 cases of PTEN mutation, 2 cases of MET amplification, 1 case of ERBB2 mutation, 1 case of KRAS mutation, 1 case of RET rearrangement, and 1 case of ALK rearrangement. There were statistically significant differences between the EGFR mutation group and the EGFR co-mutation group in the maximum tumor diameter ( χ2=5.04, P=0.025) and stage ( χ2=3.92, P=0.048). The ORRs of the two groups were 64.63% (53/82) and 37.84% (28/74), respectively, with a statistically significant difference ( χ2=11.19, P<0.001). The DCRs were 96.34% (79/82) and 86.49% (64/74), respectively, with a statistically significant difference ( χ2=4.95, P=0.026). The ctDNA levels in the EGFR mutation group and EGFR co-mutation group after one month of treatment decreased compared to before treatment[2.63 (1.83, 3.30) ng/μl vs. 4.73 (3.92, 5.49) ng/μl, Z=-7.06, P<0.001; 4.26 (2.26, 6.07) ng/μl vs. 5.28 (4.37, 6.09) ng/μl, Z=-5.15, P<0.001], the ctDNA levels in the EGFR co-mutation group were higher than those in the EGFR mutation group before treatment and after 1 month of treatment ( Z=-2.47, P=0.013; Z=-4.29, P<0.001). In the EGFR co-mutation group, the ctDNA levels in peripheral blood of patients who were effectively treated with targeted therapy decreased after 1 month of treatment compared to before treatment [(2.03±0.63) ng/μl vs. (3.92±0.82) ng/μl, t=42.94, P<0.001], the levels of ctDNA in peripheral blood of ineffectively treated patients before and after 1 month of treatment were higher than those of effectively treated patients [(5.84±0.57) ng/μl vs. (3.92±0.82) ng/μl, t=-11.91, P<0.001; (5.87±1.64) ng/μl vs. (2.03±0.63) ng/μl, t=-14.43, P<0.001]. The median PFS of the EGFR mutation group and the EGFR co-mutation group of patients were 10.4 and 8.3 months, respectively, with a statistically significant difference ( χ2=22.28, P<0.001). Univariate analysis suggested that the maximum tumor diameter ( HR=0.10, 95% CI: 0.06-0.16, P<0.001), performance status (PS) score ( HR=0.09, 95% CI: 0.06-0.15, P<0.001), stage ( HR=0.09, 95% CI: 0.05-0.14, P<0.001), pre-treatment ctDNA level ( HR=12.04, 95% CI: 8.21-17.65, P<0.001), ctDNA level after 1 month of treatment ( HR=3.75, 95% CI: 3.10-4.54, P<0.001) and EGFR co-mutations ( HR=2.21, 95% CI: 1.57-3.12, P<0.001) were found to be significant factors affecting the PFS of stage ⅢB-Ⅳ lung adenocarcinoma patients receiving targeted therapy; Multivariate analysis demonstrated that PS score ( HR=0.25, 95% CI: 0.14-0.47, P<0.001), stage ( HR=0.49, 95% CI: 0.24-0.98, P=0.044), pre-treatment ctDNA level ( HR=4.73, 95% CI: 3.08-7.28, P<0.001), ctDNA level after 1 month of treatment ( HR=2.15, 95% CI: 1.65-2.80, P<0.001), and EGFR gene co-mutation ( HR=2.26, 95% CI: 1.40-3.64, P<0.001) were independent risk factors for PFS in stage ⅢB-Ⅳ lung adenocarcinoma patients receiving targeted therapy. Conclusion:Both the EGFR mutation group and EGFR co-mutation group show a decrease in ctDNA levels after targeted therapy for one month compared to before treatment. The median PFS of EGFR co-mutation patients is shorter than that of patients with a single EGFR mutation. PS score, stage, ctDNA levels before and after treatment, and EGFR gene co-mutation are all independent factors affecting PFS in stage ⅢB-Ⅳ lung adenocarcinoma patients after targeted therapy.
