Doctor-patient communication not only depends on the medical group but is also affected by the patient group and the specific situation. Effective doctor-patient communication requires the doctors to improve their communication skills， the patients to have relevant knowledge regarding a certain symptom or disease， and mutual trust between the doctor and patient. The information ecology theory mainly analyzes the relationships between various ecological elements and the ecological development mechanisms in the process of information activities from the perspective of the ecosystem， as well as attaches importance to the mutual influences and roles of information subjects and objects， information contents， information environment， and information technology within the system， which is consistent with the influencing factors of doctor-patient communication. Based on the information ecology theory， this paper analyzed the new problems faced by doctor-patient communication under the information technology environment from the four dimensions， including information subjects and objects， information itself， information context， and information technology. It was proposed that effective doctor-patient communication required to re-examine the influencing factors of doctor-patient communication， as well as construct a doctor-patient community， including a community of knowledge， communication， emotion， and interest， so that the four factors of doctor-patient communication can form a new balance in the dynamic development， with a view to providing practical guidance for doctor-patient trust and effective doctor-patient communication.

Objective To explore the clinical value of artificial intelligence (AI) quantitative parameters in distinguishing pathological grades of stageⅠ invasive adenocarcinoma (IAC). Methods Clinical data of patients with clinical stageⅠ IAC admitted to Yantaishan Hospital Affiliated to Binzhou Medical University from October 2018 to May 2023 were retrospectively analyzed. Based on the 2021 WHO pathological grading criteria for lung adenocarcinoma, IAC was divided into gradeⅠ, grade Ⅱ, and grade Ⅲ. The differences in parameters among the groups were compared, and logistic regression analysis was used to evaluate the predictive efficacy of AI quantitative parameters for grade Ⅲ IAC patients. Parameters were screened using least absolute shrinkage and selection operator (LASSO) regression analysis. Three machine learning models were constructed based on these parameters to predict grade Ⅲ IAC and were internally validated to assess their efficacy. Nomograms were used for visualization. Results A total of 261 IAC patients were included, including 101 males and 160 females, with an average age of 27-88 (61.96±9.17) years. Six patients had dual primary lesions, and different lesions from the same patient were analyzed as independent samples. There were 48 patients of gradeⅠ IAC, 89 patients of grade Ⅱ IAC, and 130 patients of grade Ⅲ IAC. There were statitical differences in the AI quantitive parameters such as consolidation/tumor ratio (CTR), ect among the three goups. (P<0.05). Univariate analysis showed that the differences in all variables except age were statistically significant (P<0.05) between the group gradeⅠ+grade Ⅱand the group grade Ⅲ . Multivariate analysis suggested that CTR and CT standard deviation were independent risk factors for identifying grade Ⅲ IAC, and the two were negatively correlated. Grade Ⅲ IAC exhibited advanced TNM staging, more pathological high-risk factors, higher lymph node metastasis rate, and higher proportion of advanced structure. CTR was positively correlated with the proportion of advanced structures in all patients. This correlation was also observed in grade Ⅲ but not in gradeⅠand grade ⅡIAC. CTR and CT median value were selected by using LASSO regression. Logistic regression, random forest, and XGBoost models were constructed and validated, among which, the XGBoost model demonstrated the best predictive performance. Conclusion Cautious consideration should be given to grade Ⅲ IAC when CTR is higher than 39.48% and CT standard deviation is less than 122.75 HU. The XGBoost model based on combined CTR and CT median value has good predictive efficacy for grade Ⅲ IAC, aiding clinicians in making personalized clinical decisions.

(+)-Strebloside, a significant bioactive compound isolated from the roots of Streblus asper Lour., demonstrates inhibitory effects against multiple malignancies. However, its specific function and underlying mechanistic pathways in Non-Hodgkin lymphoma (NHL) remain unexplored. This investigation sought to elucidate the role and potential mechanisms of (+)-strebloside-induced NHL cell death. The results demonstrated that (+)-strebloside significantly induced apoptosis and ferroptosis in NHL cells, including those from Raji cell-derived xenograft models. Mechanistic analyses revealed that (+)-strebloside enhanced six-transmembrane epithelial antigen of prostate 3 (STEAP3)-induced ferroptosis in NHL, and STEAP3 inhibition reduced the proliferation-inhibitory effects of (+)-strebloside. Furthermore, (+)-strebloside suppressed NHL proliferation through the mitogen-activated protein kinase (MAPK) pathway, and extracellular signal-regulated kinase (ERK) inhibition diminished the proliferation-inhibitory activity induced by (+)-strebloside. These findings indicate that (+)-strebloside presents promising therapeutic potential for NHL treatment.

OBJECTIVE: To identify phytochemical constituents present in the extract of flowers of Xanthoceras sorbifolia and evaluate their anti-oxidant and anti-hyperglycemic capacities. METHODS: The AlCl₃ colorimetric method and Prussian Blue assay were used to determine the contents of total flavonoids and total phenolic acids in extraction layers, and the bioactive layers was screened through anti - oxidative activity in vitro. The Waters ACQUITY UPLC system and a Waters ACQUITY UPLC BEH C₁₈ column (2.0 mm × 150 mm, 5 μm) were used to identify the ingredients. And anti-oxidative ingredients were screened by off-line UPLC-QTOF-MS/MS-free radical scavenging. The ameliorative role of it was further evaluated in a high-fat, streptozotocin-induced type 2 diabetic rat model and the study was carried out on NADPH oxidase (PDB ID: 2CDU) by molecular docking. RESULTS: Combined with the results of activity screening in vitro, the anti - oxidative part was identified as the ethyl acetate layer. A total of 24 chemical constituents were identified by liquid chromatography-mass spectrometry in the ethyl acetate layer and 13 main anti-oxidative active constituents were preliminarily screened out through off-line UPLC-QTOF-MS/MS-free radical scavenging. In vivo experiments showed that flowers of X. sorbifolia could significantly reduce the blood glucose level of diabetic mice and alleviate liver cell damage. Based on the results of docking analysis related to the identified phytocompounds and oxidase which involved in type 2 diabetes, quercetin 3-O-rutinoside, kaempferol-3-O-rhamnoside, isorhamnetin-3-O-glucoside, and isoquercitrin showed a better inhibitory profile. CONCLUSION The ethyl acetate layer was rich in flavonoids and phenolic acids and had significant anti-oxidant activity, which could prevent hyperglycemia. This observed activity profile suggested X. sorbifolia flowers as a promising new source of tea to develop alternative natural anti-diabetic products with a high safety margin.

Transradial approach is the classical access for coronary angiography and percutaneous coronary intervention (PCI). With the increase in the number of interventional procedures, some disadvantages of the transradial approach have also been found, it is easy to lead to various complications, such as radial artery occlusion, radial nerve injury, and puncture difficulties after radial artery spasm. Therefore, some experts put forward the approach of distal radial artery approach for interventional therapy, which has the advantages of convenient positioning, easy postoperative hemostasis, less damage to the proximal radial artery and improving patients' comfort. However, there is no special distal radial artery hemostat in clinic, which limits the development of this approach to a certain extent. Therefore, based on the principles of anatomy and physics, cardiovascular physician at Jiading District District Central Hospital in Shanghai designed and invented a distal radial artery hemostatic device, which is convenient for clinical hemostasis of distal radial artery puncture, and obtained the National Utility Model Patent (patent number: ZL 2021 2 2097829.6). The hemostatic device consists of a glove body with a silicone gasket protruding towards the skin on the inner surface and a binding component. The patient's hand is inserted into the glove body, and after being fixed by the restraint component, the silicone gasket can effectively compress the location of the radial artery puncture point, and play a good hemostatic effect with less pressure, avoid the common complications of proximal radial artery hemostatic, and reduce the discomfort of the patient. Has good application value.

Objective To investigate the acute toxicity,irritation,and other effects of Shexiang Anhe hemorrhoid ointment on hemorrhoid-phased model rats by examining the TLR4/p38 MAPK/NF-κB signaling pathway.Methods Sixteen New Zealand rabbits were randomly divided into an intact skin Shexiang Anhe hemorrhoid ointment group,intact skin control group,broken skin Shexiang Anhe hemorrhoid ointment group,and broken skin control group,with four rabbits in each group.In the experimental group,20 g of Shexiang Anhe hemorrhoid ointment(1 g/mL)was evenly applied to an area on the rabbits depleted of hair,and an equal volume of solvent(mixture of glycerol,lanolin,and water)was evenly applied to the area on the backs of the rabbits in the control group once a day for 14 days.Another 40 rats were taken and randomly divided into a normal group,model group,Maillard group,and hemorrhoid cream group,with 10 animals in each group.The cream was applied once a day for 14 days.The acute toxicity of the cream in the intact and broken skin of rabbits was observed by hematoxylin and eosin staining and other method after treatment.In situ photographs were taken of the perianal tissues of rats with hemorrhoids to observe the efficacy of Shexiang Anhe hemorrhoid ointment,and the length and width of the ulcers were measured with vernier calipers to calculate the area.Quantitative real time polymerase chain reaction was used to detect the expression of TLR4,p38 MAPK,and NF-κB mRNA in the perianal tissues of the rats.Results Compared with rabbits in the control groups with intact or broken skin,rabbits in the administered group showed no significant difference in body mass.The mean values for the irritation evaluation points for Shexiang Anhe hemorrhoid ointment on rabbits with broken skin for 1 h,24 h,48 h,and 72 h were 1.5,1,0.5,and 0.25,respectively,showing there was no obvious skin irritation.In the hemorrhoidal rats,Shexiang Anhe hemorrhoid ointment treatment significantly reduced hemorrhoid symptoms after 14 days administration;the ulcer area was significantly smaller(P＜0.05)and TLR4,p38 MAPK,and NF-κB mRNA levels were significantly lower compared with the findings in the model group(P＜0.05).Conclusions Shexiang Anhe hemorrhoid ointment is a safe topical treatment with minimal acute toxicity and irritation to the skin and achieved good efficacy in the treatment of hemorrhoidal rats.Its mechanism of action may be related to the inhibition of the TLR4/p38 MAPK/NF-κB signaling pathway.

Objective To observe the effect of abdominal acupuncture in treating allergic rhinitis(AR).Methods Twenty-seven AR patients who attended Fangshan Hospital,Beijing University of Chinese Medicine from August to October 2022 were selected.They were divided into treatment group(15 cases)and control group(12 cases)according to randomized numerical table method.The treatment group received abdominal acupuncture.The control group at the same point was used one-time sterile cannula acupuncture to simulate acupuncture,but no needle was inserted into the acupoint.Two groups were treated,3 times a week for 4 weeks.The visual analogue scale(VAS),rhinoconjunctivitis quality of life questionnaire(RQLQ),Pittsburgh sleep quality index(PSQI)scores,and the histamine(HIS),leukotriene D4(LTD4),immunoglobulin E(IgE)levels were compared between two groups before and after treatment.Results At each time point after treatment,the VAS,RQLQ,PSQI scores and HIS,LTD4,IgE levels of patients in treatment group were significantly lower than those before treatment(P<0.05).There were no statistically significant differences in VAS,RQLQ,and PSQI scores,the HIS,LTD4,and IgE levels after 2-week treatment in both groups(P>0.05).After 4-week treatment and follow-up 4-week,the VAS,RQLQ,and PSQI scores,the HIS,and LTD4 levels in treatment group were significantly lower than those in control group(P<0.05).Conclusion Abdominal acupuncture has good therapeutic effect on AR and significantly improves life quality of the patients,which can reduce the levels of HIS,LTD4 and IgE.The therapy is worthy of clinical application.

Objective To investigate the predictive value of preoperative blood inflammatory markers for the recurrence risk in patients with basal cell carcinoma(BCC).Methods A total of 225 patients with BCC were divided into the high-risk recurrence group(155 cases)and the low-risk recurrence group(70 cases).General information and preoperative hematological indicators were collected in the two groups of patients.The neutrophil-to-lymphocyte ratio(NLR),lymphocyte-to-monocyte ratio(LMR),systemic inflammation marker(SIM)and platelet-to-lymphocyte ratio(PLR)were calculated.Receiver operating characteristic(ROC)curves were used to determine the predictive value of hematological markers with statistically significant differences between the two groups for BCC recurrence and to establish optimal cutoff values.Univariate and multivariate Logistic regression analyses were conducted to identify factors influencing BCC recurrence.A multivariate Logistic regression model was established to predict the recurrence risk of BCC.Area under the curve(AUC)and the Hosmer-Lemeshow test were used to evaluate the prediction efficiency and goodness-of-fit of the model.Results ROC analysis identified that optimal cutoff values for LMR and SIM were 5.12 and 0.86,respectively.Univariate Logistic regression analysis showed that LMR,SIM,ulceration at the primary tumor site,UV exposure and tumor maximum diameter were factors influencing BCC recurrence.Multivariate Logistic regression revealed that SIM≥0.86,tumor maximum diameter≥2.0 cm and UV exposure were risk factors for BCC recurrence,while LMR≥5.12 had a protective effect.The Logistic prediction model for BCC recurrence risk was Logit(P)=-1.598-1.517×LMR+1.323×SIM+2.406×UV exposure+3.465×tumor maximum diameter,with good model fit(P=0.725)and an AUC of 0.869(95%CI:0.822-0.917)for predicting BCC recurrence risk.Conclusion Monitoring preoperative LMR and SIM levels can assist in assessing the risk of recurrence in BCC patients and provide important guidance for clinical decision-making.

Objective:To investigate the risk factors for high-output stoma (HOS) in patients undergoing rectal cancer radical resection combined with terminal ileostomy.Methods:A retrospective analysis was conducted on the medical records of 104 patients who underwent radical resection for rectal cancer combined with terminal ileostomy at Northern Jiangsu People′s Hospital from January 2020 to December 2022. Among them, 77 were male and 27 were female, with ages ranging from 31 to 84 years and an average age of 62.60 years. HOS was defined as an average stoma output ≥1500 mL/24 h within 3 days after resuming oral intake. Based on the presence of HOS post-surgery, patients were divided into the HOS group ( n=29) and the non-HOS group ( n=77). The two groups were compared based on gender, age, body mass index (BMI), preoperative albumin, hemoglobin, fasting blood glucose, surgery duration, surgical approach, intraoperative blood loss, postoperative albumin, hemoglobin, white blood cell count, and C-reactive protein (CRP). Data were analyzed using SPSS27.0. Continuous data were expressed as mean±standard deviation( ± s), and independent t-tests or non-parametric tests were used for group comparisons. Chi-square tests were used for categorical data, and logistic regression was employed to evaluate the influence of various factors on the occurrence of HOS. Results:There were no statistically significant differences between the two groups in terms of gender, preoperative albumin, hemoglobin, fasting blood glucose, surgery duration, surgical approach, intraoperative blood loss, postoperative albumin, hemoglobin, or white blood cell count ( P>0.05). Univariate logistic regression analysis indicated that older patients were more likely to develop HOS ( P=0.037, OR=1.047), those with lower BMI were at higher risk of HOS ( P<0.001, OR=0.448), and elevated postoperative CRP was associated with an increased likelihood of HOS ( P<0.001, OR=1.027). Multivariate logistic regression analysis showed that BMI ( OR=0.302, 95% CI: 0.164-0.555, P<0.001) and postoperative CRP ( OR=1.045, 95% CI: 1.023-1.068, P<0.001) were independent risk factors for the occurrence of HOS. Conclusion:Lower BMI and elevated postoperative CRP are significant independent risk factors for the development of HOS in rectal cancer patients.
