OBJECTIVE To compare the anti-hepatitis mechanisms of Abrus pulchellus subsp. cantoniensis （Hance） Verdc. （AC） and Abrus pulchellus subsp. mollis（Hance） Verdc. （AM）. METHODS SD rats were randomly divided into blank group， AC- treated group， and AM-treated group， with each group consisting of 10 rats. The rats’ orbital venous blood was collected at 5， 15， 30 minutes， and 1， 1.5， 2， 4， 6， 8， 12 hours after gavage administration of 24 g/kg of the corresponding drug （calculated by crude drug） or water， respectively. Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry technology was utilized to identify the prototype components present in the serum. The network pharmacology method was adopted to predict the anti-hepatitis active components， key targets， and signaling pathways of AC and AM. Additionally， molecular docking technology was utilized to verify the binding activity of the core active components with key targets. RESULTS A total of 35 prototype components migrating to the blood of AC and AM were identified in the serum of administered rats， among which 24 were common components. The active components in AC， such as acetylanguidine， physcion， soyasaponin A3 and soyasaponin Ⅰ， as well as those in AM， including vicenin 3， acetylanguidine，soyasaponin Ⅰ and schaftoside， all acted on key targets such as steroid receptor coactivator， phosphatidylinositol-4，5-bisphosphate 3-kinase catalytic subunit alpha， epidermal growth factor receptor （EGFR）， and protein kinase B1（Akt1）. These components modulated pathways in cancer， EGFR tyrosine kinase inhibitor resistance， and the phosphoinositide 3-kinase （PI3K） -Akt pathway， thereby exerting anti-hepatitis effects. Furthermore， the binding energies between these active components and their key targets were all less than －5 kJ/mol. CONCLUSIONS There are differences in the active components of AC and AM against hepatitis， but their mechanisms of action are similar. Both may exert their anti-hepatitis effects through pathways in cancer， EGFR tyrosine kinase inhibitor resistance， and the PI3K-Akt pathway.

Objective:To explore the application effect of group guidance based on intelligent communication matrix in patients with type 2 diabetes mellitus (T2DM) .Methods:Using the convenient sampling method, a total of 60 T2DM patients with poor self-management ability who scored less than 19.6 on Summary of Diabetes Self Care Activities (SDSCA) in the Affiliated Chuzhou Hospital of Anhui Medical University were selected as the research objects from May to June 2020. They were randomly divide into the observation group ( n=30) and the control group ( n=30). The observation group was given continuous group guidance based on intelligent communication matrix, while the control group was given routine health guidance. The SDSCA score, body mass index and glycosylated hemoglobin (HbA1c) before and after intervention were compared between the two groups. Results:After intervention, the SDSCA score of the observation group was higher than that of the control group, HbA1c was lower than that of the control group and body mass index was lower than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The group guidance based on intelligent communication matrix can improve the self-management level of T2DM patients and reduce their body mass index and HbA1c levels, which has clinical application value.

Objective:To explore the diagnostic value of improved 18F-prostate specific membrane antigen (PSMA)-1007 PET-CT score (referred to as PSMA score) and multi parameter magnetic resonance imaging (mpMRI) prostate imaging reporting and data system (PI-RADS) score (referred to as PI-RADS score) for primary prostate cancer (PCa). Methods:A retrospective case series study was conducted. The imaging and clinical data of 134 suspected PCa patients underwent 18F-PSMA-1007 PET-CT and mpMRI examinations at Shanxi Province Cancer Hospital from July 2018 to May 2023 were collected. Pathological diagnosis showed 92 cases of PCa and 42 cases of benign prostatic lesions. The clinical and imaging parameters, as well as the distribution of patients with two scores, were compared between the two groups. The blind diagnosis of benign and malignant lesions was made based on the improved PSMA score (dividing 1 point into 1a and 1b points, 1b, 2 and 3 points were diagnosed as PCa), PI-RADS score (3, 4 and 5 points were diagnosed as PCa) and the combination of the two (diagnosed as PCa when either PSMA score ≥ 1b point or PI-RADS score ≥ 4 points was met). The indicators of the diagnostic efficiency of PSMA score, PI-RADS score and the combination of the two for PCa were calculated. Using pathological results as the gold standard, the receiver operating characteristic (ROC) curve of PSMA score, PI-RADS score and the combination of the two for diagnosing PCa was drawn, and the diagnostic efficiency of the 3 methods was analyzed. Results:The age, serum prostate-specific antigen, and maximum standard uptake value of PET-CT in the PCa group were higher than those in the benign prostatic lesion group, and the differences were statistically significant (all P < 0.05). The sensitivity, specificity, accuracy, false negative rate, false positive rate, positive predictive value, and negative predictive value of PSMA score for diagnosing PCa were 91.30% (84/92), 80.95% (34/42), 88.06% (118/134), 8.70% (8/92), 19.05% (8/42), 91.30% (84/92), and 80.95% (34/42), respectively; those of PI-RADS score were 93.48% (86/92), 61.90% (26/42), 83.58% (112/134), 61.90% (26/42), 38.10% (16/42), 84.31% (86/102), and 81.25% (26/32), respectively; those of the combination of the two were 97.83% (90/92), 88.10% (37/42), 94.78% (127/134), 2.17% (2/92), 11.90% (5/42), 94.74% (90/95), and 94.87% (37/39), respectively. The differences in specificity, accuracy, false negative rate, and false positive rate among the 3 methods were statistically significant (all P < 0.05). ROC curve analysis showed that the area under the curve of PSMA score, PI-RADS score and the combination of the two for diagnosing PCa were 0.930 (95% CI: 0.872-0.967), 0.935 (95% CI: 0.826-0.939) and 0.959 (95% CI: 0.910-0.986), respectively, and the differences between each two methods were statistically significant (all P < 0.05); the sensitivity of PSMA score, PI-RADS score and the combination of the two was 90.11%, 89.13% and 98.09%, and the specificity was 90.48%, 90.48% and 92.09%. Conclusions:Compared with the PI-RADS score, the improved PSMA score can improve the specificity and accuracy of PCa diagnosis, and decrease the false negative and false positive rates; the diagnostic efficiency of the combination of the two is superior.

Purpose: To understand the recurrence risk perception of stroke patients and develop a chain mediation model of recurrence risk perception and health behavior. Methods: A cross-sectional study and convenience sampling were used. Stroke survivors were recruited from the neurology departments of three tertiary hospitals. Their recurrence risk perception, behavioral decision-making, social support, self-efficacy, recurrence worry, and health behavior were measured by relevant tools. Data was analyzed through one-way analysis and regression analysis, and the AMOS 21.0 software was used to explore the mediating relationships between variables. Results: Of the 419 participants, 74.7% were aware of stroke recurrence risk. However, only 28.2% could accurately estimate their own recurrence risk. Recurrence risk perception was significantly correlated with behavioral decision-making, social support, self-efficacy, and health behavior (r = .19 ∼ .50, p < .05). Social support and recurrence risk perception could affect health behavior indirectly through self-efficacy, behavioral decision-making, and worry. Behavioral decision-making acted as a main mediator between recurrence risk perception and health behavior, while the path coefficient was .47 and .37, respectively. The chain mediation effect between recurrence risk perception and health behavior was established with a total effect value of .19 (p < .01). Conclusion Most stroke survivors could be aware of recurrence risk but failed to accurately estimate their individual risk. In the mediation model of recurrence risk perception and health behavior, social support seemed to be an important external factor, while self-efficacy, behavioral decision-making, and worry seemed to act as key internal factors.

Hepatocellular carcinoma is a kind of cancer with a strong invasion, a high incidence rate and mortality, and a poor prognosis. At the time of diagnosis, most patients are already in the advanced stages of a tumor and have lost the chance for radical surgical treatment. Advanced hepatocellular carcinoma treatment has a gradual transition from systemic chemotherapy to targeted therapy, immunotherapy, and combination therapy, especially immune checkpoint inhibitor-based immunotherapy combination therapy, such as combination with bevacizumab monoclonal antibodies and other drugs, or combination with TACE, HAIC, radiotherapy, ablation, and other treatment methods. Combination therapy has significant synergistic effects and thus has already become a future treatment trend for hepatocellular carcinoma. An immunotherapy-based combination therapy plan will run through the whole process of systemic therapy, which is expected to bring better survival benefits to patients with hepatocellular carcinoma. This article reviews the latest research progress in aspects of the first-line treatment of advanced hepatocellular carcinoma.

AIM:To investigate the effects of skeletal muscle mass on cardiac structure and function in rats subjected to abdominal aortic constriction(AAC),and to explore its potential mechanisms.METHODS:(1)Thirty male SD rats were randomly divided into 3 groups:control(CON)group(n=10),muscular atrophy(MA)group(n=10),and muscular hypertrophy(MH)group(n=10).The rats in MA group underwent bilateral tibial nerve removal to induce MA,while those in MH group engaged in weight-bearing running to promote MH.Four weeks later,skeletal muscle sam-ples were collected,and indicators of MA and MH were assessed.(2)Another rats after modeling above were divided into 4 groups:CON group(n=10),cardiac pathological remodeling group(AAC group;n=10),MA+AAC group(n=10),and MH+AAC group(n=10).All rats,except those in CON group which underwent a sham operation,received AAC sur-gery.Four weeks after surgery,cardiac structure and function were assessed by echocardiography,while morphological changes of the soleus and gastrocnemius muscles and myocardium were evaluated by pathological staining.Serum myo-statin(MSTN)level was measured using ELISA.The mRNA expression levels of atrial natriuretic peptide(ANP)and brain natriuretic peptide(BNP)in the myocardium,and MSTN in the skeletal muscle and myocardium were detected by real-time PCR.RESULTS:After 4 weeks of either denervation or weight-bearing running,significant atrophy and hyper-trophy of the gastrocnemius and soleus muscles were observed in MA and MH groups,respectively,compared with CON group.However,no significant differences were noted in heart weight/body weight ratio,left ventricular end-diastolic wall thickness,ejection fraction,or other related indexes among these groups(P>0.05).In comparison to AAC group,the rats in MA+AAC group showed a significant increase in heart weight/body weight ratio and left ventricular end-diastolic an-terior wall thickness,a decrease in end-diastolic internal diameter,an increase in ejection fraction(P<0.05 or P<0.01),and exacerbated myocardial fibrosis.Conversely,in MH+AAC group,there was a significant decrease in heart weight/body weight ratio and left ventricular end-diastolic wall thickness,an increase in end-diastolic internal diameter,and a lower ejection fraction(P<0.05 or P<0.01),with reduced myocardial fibrosis.Compared with AAC group,myocardial ANP and BNP mRNA expression significantly increased in MA+AAC group and decreased in MH+AAC group(P<0.01).Additionally,soleus and gastrocnemius muscle MSTN mRNA expression,myocardial MSTN mRNA expression,and se-rum MSTN level significantly increased in MA+AAC group(P<0.01)and significantly decreased in MH+AAC group(P<0.05).CONCLUSION:Atrophic skeletal muscle exacerbated the pathological remodeling induced by AAC surgery,whereas hypertrophic skeletal muscle mitigated this remodeling.Skeletal muscle mass plays a critical role in cardiac patho-logical remodeling,with MSTN potentially regulating this process.

Pulmonary fibrosis is a respiratory system disorder characterized by damage to alveolar epithelial cells,pathological proliferation and transformation of fibroblasts,excessive deposition of extracellular matrix,leading to structural damage and loss of function in lung tissues,with a high mortality rate and limited effective treatment methods.This article was based on the TCM understanding of"lung connecting to large intestine",namely the theory of"lung and the large intestine being interior-exterior related",and set the modern medical understanding of"lung connecting to large intestine",namely the theory of"gut-lung axis"as the key.Combining the TCM pathogenesis of pulmonary fibrosis and the related mechanisms of"gut-lung axis"in pulmonary fibrosis,it preliminarily expounded the connotation of TCM regulating the"gut-lung axis"to treat pulmonary fibrosis,aiming to provide new ideas for clinical treatment of pulmonary fibrosis through the"gut-lung axis".

Objective:To evaluate the clinical value of the adjusted global antiphospholipid syndrome score (aGAPSS) in patients with persistent antiphospholipid antibodies (aPL).Methods:The clinical data of patients who were continuously positive for aPL from May 2012 to August 2022 were retrospectively analyzed, except for patients complicated with connective tissue diseases. Demographic data, traditional cardiovascular thrombosis risk factors, aPL profile, and clinical manifestations included and not included in antiphospholipid syndrome (APS) were collected, and aGAPSS was calculated for all patients according to risk indicators and the correlation with clinical manifestation was analyzed through rank sum test. The diagnostic value of aGAPSS for different clinical manifestations was evaluated by the receiver operator characteristic (ROC) curve.Results:A total of 67 patients with persistent aPL were enrolled, including 15 patients with persistent extra-criteria positive aPL but did not meet the APS classification criteria and 52 patients with a clear diagnosis of primary APS, of which 20 had a history of thrombosis, 36 had a history of pregnancy morbidity, and 24 had extra-criteria clinical manifestations. Patients with history of any thrombosis or arterial thrombosis scored significantly higher than those with no history of thrombosis [any history of thrombosis 11.50 (8.25, 13.00) vs 8.00 (4.00, 13.00), Z=2.33, P=0.020; arterial thrombosis history 11.00 (9.00, 14.00) vs 8.00 (4.00, 13.00), H=6.21, P=0.043]. The aGAPSS score of patients with extra-criteria clinical manifestations was significantly higher than that of patients without corresponding clinical manifestations [13.00 (8.25, 13.00) vs 8.00 (4.00, 11.00), Z=2.81, P=0.005], and the aGAPSS score of patients with thrombocytopenia was significantly higher than that of patients without thrombocytopenia [12.50 (8.00, 13.25) vs 8.00 (4.00, 13.00), Z=2.23, P=0.026]. A subgroup analysis of pregnant women found no statistically significant difference in aGAPSS scores between groups with or without a history of pregnancy morbidity. With thrombosis as the endpoint event, aGAPSS had the highest diagnostic value at 10 points(sensitivity and specificity were 65.00% and 77.78%, respectively). Conclusion:In patients with postivity aPL positivity, aGAPSS score is correlated with thrombosis history and extra-criteria clinical manifestations, especially thrombocytopenia.

Hepatocellular carcinoma （HCC） is a common tumor in the digestive tract， the formation mechanism of which remains to be fully elucidated. Although surgery， radiation， chemotherapy， targeted therapy， and immunotherapy have achieved significant results in the treatment of HCC， these methods are accompanied by a considerable number of adverse reactions and complications. In recent years， Chinese medicine has shown remarkable efficacy in the treatment of HCC， and both basic experiments and clinical studies have confirmed the effectiveness of Chinese medicine， which exerts therapeutic effects via multiple components and multiple targets. However， the pathogenesis of HCC is exceptionally complex and not fully understood， which means that studies remain to be carried out regarding the specific mechanism of Chinese medicine in preventing and treating HCC. Network pharmacology and molecular biology can be employed to decipher the mechanism of Chinese medicine in the treatment of diseases. Studies have shown that Chinese medicine can regulate various pathways such as the mitogen-activated protein kinase （MAPK）， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Hedgehog， Wnt/β-catenin， nuclear factor-κB （NF-κB）， Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3）， and transforming growth factor-β （TGF-β）/Smad signaling pathways. Chinese medicine can exhibit its anti-HCC effects by inducing cell apoptosis， inhibiting cell proliferation and migration， and blocking the cell cycle via the above pathways. However， the specific mechanisms remain to be systematically studied. This study comprehensively reviews the regulatory effects of Chinese medicine on HCC-related signaling pathways to reveal the molecular mechanisms of Chinese medicine in the treatment of HCC. This view holds the promise of providing new targets， new perspectives， and new therapies for HCC treatment and advancing the modernization and development of Chinese medicine.
