ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory， Qijia Rougan prescription， combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted， and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis （CHB-HF） who met the diagnosis and inclusion criteria were randomly assigned to an observation group （Qijia Rougan prescription + entecavir） and a control group （entecavir）. The treatment duration was 24 weeks. Liver stiffness measurement （LSM）， fibrosis-4 index （FIB-4）， portal vein diameter， hepatitis B serology， biochemical indicators， hepatic fibrosis markers in serum ［hyaluronic acid （HA）， laminin （LN）， procollagen Ⅲ peptide （PⅢP）， and type Ⅳ collagen （Ⅳ-C）］， and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis， with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment， the observation group showed a significant reduction in LSM and FIB-4 （P<0.01）， as well as notable improvements in LN， Ⅳ-C， and various TCM syndrome scores （P<0.05， P<0.01）. When compared to the control group after treatment， the observation group demonstrated significant improvements in LSM， FIB-4， and various TCM syndrome score indicators （P<0.05， P<0.01）， indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment， the observation group had better improvement in regression of stages F2 and F3 （P<0.05）. When compared to the control group after treatment， the observation group exhibited superior improvement in regression of stage F3 （P<0.05）. No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone， the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3， which is a potential “interception” point of the “Zhu Ke Jiao” theory.

AIM: To analyze changes in the anterior chamber angle structure in patients with implantable collamer lens with central-port(ICL V4c)implantation, and to investigate their associations with preoperative anterior segment anatomical parameters.METHODS: Retrospective case study. Patients with myopia or myopia combined with astigmatism who underwent ICL V4c implantation in the Refractive Surgery Center of the Department of Ophthalmology, the 2nd Affiliated Hospital of Harbin Medical University between July 2024 and November 2024 were recruited. Preoperative and postoperative uncorrected visual acuity, best-corrected visual acuity, intraocular pressure, anterior chamber angle(ACA), white-to-white distance(WTW), anterior chamber depth(ACD), angle to angle distance(ATA), horizontal sulcus-to-sulcus distance(HSTS), vertical sulcus-to-sulcus distance(VSTS),crystalline lens rise(CLR), pupil diameter(PD), iris thickness at 750 μm from the scleral spur(IT750),maximal iris thickness(ITM), iris curvature(I-Curv), and iris cross-sectional area(I-Area), angle opening distance(AOD750), thetrabecular-iris angle(TIA750)and the trabecular-iris space area(TISA750)in the temporal, nasal, superior, and inferior directions,as well as the vault at various postoperative time points were measured.RESULTS: The study involved 40 patients(79 eyes)with myopia or myopia combined with astigmatism who underwent ICL V4c implantation(10 males and 30 females)with the mean age of 24.73±3.79 y. Compared with preoperative measurements, at 1 mo postoperatively, the AOD750, TIA750, and TISA750 parameters at the four angles(temporal, nasal, superior, and inferior)all showed a significant reduction(P<0.01). Statistically significant differences in vault were observed at postoperative 1d(0.49±0.1), postoperative 1 wk(0.43±0.14), and postoperative 1 mo(0.41±0.14)(all P<0.001). Correlation analysis indicated that the postoperative state of the anterior chamber angle was jointly influenced by anterior chamber parameters(ACD, ATA, HSTS、VSTS), iris morphology(I-Area, IT750), pupil size(PD), and surgical factors(ICL size, early vault), and that the combination of influencing factors varied across different orientations. Regression analysis showed that ACD was positively correlated with all postoperative anterior chamber angle parameters(P<0.05). IT750 exhibited negative correlations with the temporal and inferior angles(P<0.05). I-Area was positively correlated with temporal AOD750 and TISA750(P<0.05), and PD had negative correlations with temporal TIA750 and nasal AOD750(P<0.05).CONCLUSION: Postoperative anterior chamber angle narrowing is a common phenomenon after ICL V4c implantation. The degree of change exhibits a significant correlation with multiple preoperative anterior segment anatomical parameters. Preoperative comprehensive assessment of ACD, PD, and IT750 may facilitate the evaluation of the risk of postoperative angle changes and the enhancement of surgical safety.

Elderly patients with lung cancer have a significantly increased risk of perioperative cardiopulmonary complications due to physiological decline, high incidence of complications and reduced surgical tolerance, which directly affects postoperative recovery and long-term survival. Although the concepts of minimally invasive surgery and enhanced recovery after surgery have improved clinical outcomes, early recognition and intervention of postoperative complications in elderly patients remains a significant challenge in the field of thoracic surgery. By integrating recent literature and clinical practice, this paper systematically analyzes the pathophysiological mechanism and risk factors of perioperative cardiopulmonary complications in elderly patients with lung cancer, and discusses individualized intervention strategies based on risk stratification and multidisciplinary team, in order to provide theoretical basis and practical guidance for optimizing perioperative management and improving postoperative prognosis in elderly patients.

Objective: To investigate the urban and rural differences in adverse outcomes of pulmonary tuberculosis (PTB) in patients with pulmonary tuberculosis-diabetes mellitus comorbidity (PTB-DM), so as to provide insights into improving the prevention and treatment measures for PTB-DM. Methods: Patients with PTB-DM who were admitted and discharged from 14 designated tuberculosis hospitals in Hangzhou City from 2018 to 2022 were selected. Basic information, and history of diagnosis and treatment were collected through hospital information systems. The adverse outcomes of PTB were defined as endpoints, and the proportions of adverse outcomes of PTB in urban and rural patients with PTB-DM were analyzed. Factors affecting the adverse outcomes of PTB were identified using a multivariable Cox proportional hazards regression model. Results: A total of 823 patients with PTB-DM were enrolled, including 354 (43.01%) urban and 469 (56.99%) rural patients. There were 112 (13.61%) patients with adverse outcomes of PTB. The proportions of adverse outcomes of PTB in urban and rural patients were 14.41% and 13.01%, respectively, with no statistically significant difference (P>0.05). Multivariable Cox proportional hazards regression analysis identified first diagnosed in county-level hospitals or above (HR=2.107, 95%CI: 1.181-3.758) and drug resistance (HR=3.303, 95%CI: 1.653-6.600) as the risk factors for adverse outcomes of PTB in urban patients with PTB-DM, while the treatment/observed management throughout the process (HR=0.470, 95%CI: 0.274-0.803) and fixed-dose combinations throughout the process (HR=0.331, 95%CI: 0.151-0.729) as the protective factors for adverse outcomes in rural patients with PTB-DM. Conclusions There are differences in influencing factors for adverse outcomes of PTB in urban and rural patients with PTB-DM. The adverse outcomes of PTB are associated with first diagnosed hospitals and drug resistance in urban patients, and are associated with the treatment/observed management and fixed-dose combinations throughout the process in rural patients.

Risk prediction models for postoperative pulmonary complications (PPCs) can assist healthcare professionals in assessing the likelihood of PPCs occurring after surgery, thereby supporting rapid decision-making. This study evaluated the merits, limitations, and challenges of these models, focusing on model types, construction methods, performance, and clinical applications. The findings indicate that current risk prediction models for PPCs following lung cancer surgery demonstrate a certain level of predictive effectiveness. However, there are notable deficiencies in study design, clinical implementation, and reporting transparency. Future research should prioritize large-scale, prospective, multi-center studies that utilize multiomics approaches to ensure robust data for accurate predictions, ultimately facilitating clinical translation, adoption, and promotion.

Identifying drug-drug interactions(DDIs)is essential to prevent adverse effects from polypharmacy.Although deep learning has advanced DDI identification,the gap between powerful models and their lack of clinical application and evaluation has hindered clinical benefits.Here,we developed a Multi-Dimensional Feature Fusion model named MDFF,which integrates one-dimensional simplified molec-ular input line entry system sequence features,two-dimensional molecular graph features,and three-dimensional geometric features to enhance drug representations for predicting DDIs.MDFF was trained and validated on two DDI datasets,evaluated across three distinct scenarios,and compared with advanced DDI prediction models using accuracy,precision,recall,area under the curve,and F1 score metrics.MDFF achieved state-of-the-art performance across all metrics.Ablation experiments showed that integrating multi-dimensional drug features yielded the best results.More importantly,we obtained adverse drug reaction reports uploaded by Xiangya Hospital of Central South University from 2021 to 2023 and used MDFF to identify potential adverse DDIs.Among 12 real-world adverse drug reaction reports,the predictions of 9 reports were supported by relevant evidence.Additionally,MDFF demon-strated the ability to explain adverse DDI mechanisms,providing insights into the mechanisms behind one specific report and highlighting its potential to assist practitioners in improving medical practice.

Objective:To analyse the effect of ultrasound-guided percutaneous liver biopsy and the coaxial biopsy needle tract radiofrequency ablation on patients diagnosed with hepatocellular carcinoma who are considered to be at risk of bleeding.Methods:The data of 117 patients with hepatocellular carcinoma who underwent coaxial biopsy needle tract radiofrequency ablation after ultrasound-guided percutaneous liver biopsy in Peking University First Hospital from March 2019 to April 2023 were retrospectively analysed. There were 95 males and 22 females, with the age of (62.0±11.8) years. A comprehensive analysis was conducted on the following variables: the pre-puncture platelet count, the international standardised ratio, anticoagulation therapy, the haemoglobin (Hb) level, the success rate of the liver puncture, the qualified rate of liver puncture specimens, the number of puncture samples, the length of hospital stay, the Hb level after puncture, bleeding within 10 days post-operation, and complications after ablation, including biliary fistula, hemothorax and organ perforation.Results:Among the 117 patients, 60 cases (51.3%) had an international normalized ratio >1.1, 40 cases (34.2%) had thrombocytopenia, that is, <150×10 9/L, and 17 cases (14.5%) received continuous anticoagulation therapy before the operation. It is evident that all 117 patients successfully completed the ultrasound-guided percutaneous liver biopsy, and that all liver biopsy specimens were qualified. The absence of biliary fistula, hemothorax, organ perforation or death in the patients post-ablation was noted. According to the adverse event evaluation criteria, version 5.0, 113 cases (96.6%) were classified as grade 1 and 4 cases (3.4%) were classified as grade 3. The Hb concentration of patients with minor bleeding (grade 1) prior to puncture was (119.7±22.2) g/L, which was significantly higher than the Hb concentration of patients with severe bleeding (grade 3), (76.0±10.4) g/L ( t=3.92, P=0.010). A meticulous examination of the data revealed that there were no statistically significant differences between the two groups with regard to pre-puncture platelet count, pre-puncture international standardised ratio, pre-puncture proportion of receiving anticoagulant drugs, length of hospital stay and number of puncture samples (all P>0.05). Conclusion:For patients with hepatocellular carcinoma who are at risk of bleeding, ultrasound-guided percutaneous liver biopsy followed by coaxial biopsy needle tract radiofrequency ablation can obtain satisfactory liver tissue samples and is relatively safe. There were differences in hemoglobin levels before puncture among patients with different bleeding after puncture.

In terms of the complexity of the"left"and"right"concepts,these directional terms not only indicate spatial orientation but also embody hierarchical order,official titles,systemic imbalances,and temporal sequences.This study explains the medical theory of"liver is born on the left and lung is hidden on the right,"and reveals its implications for ascending and descending of qi movement pathways,sequential patterns,non-equilibrium states,and the centrality of the middle,thus linking the connotation of this theory and its application.In view of this,the theory of"liver is born on the left and lung is hidden on the right"can be used in the clinical diagnosis and treatment of qi-blood-body fluid and emotional diseases,and guides disease prevention and treatment,as well as enhances the subjective initiative of health maintenance and longevity.This study not only deepens the modern interpretation of the classical theory but also provides novel perspectives for its application in disease prevention and treatment.

Objective:To explore the clinical and pathological features and survival outcomes of patients with early-onset intrahepatic cholangiocarcinoma (EOICC).Methods:This is a multicenter, retrospective cohort study. Data of 1 160 intrahepatic cholangiocarcinoma patients undergoing radical resection in 14 tertiary Grade A hospitals in China from January 2010 to November 2021 were retrospectively collected. The cohort included 632 males and 528 females, aged( M (IQR)) 61 (14) years (range: 22 to 93 years). ICC aged ≤50 years at the time of diagnosis was defined as EOICC and >50 years as late-onset intrahepatic cholangiocarcinoma (LOICC). Of these, there were 247 cases in the EOICC group and 913 cases in the LOICC. The clinical and pathological characteristics of both groups were analyzed and compared using the independent sample t-test, Mann-Whitney U test or Kaplan-Meier method. Univariate and multivariate Cox regression models for patient outcomes were constructed and forest graphed. Results:Compared with the patients in the LOICC group, patients in the EOICC group had lower carcinoembryonic antigen levels (2.5(4.0) μg/L vs. 3.1(5.2)μg/L, U=124 899, P=0.009) and CA19-9 level (63.4(524.7)U/ml vs. 77.9(611.3)U/ml, U=120 320, P=0.013), higher levels of ALT (29(35)U/L vs. 24(26)U/L, U=101 214, P=0.013), a lower score of the Eastern US Cooperative Oncology Group (0 score patients: 54.7% vs. 44.1%, χ2=12.472, P=0.014), higher TNM stage ( χ2=11.807, P=0.038), and proportion of lymph node dissection (62.3% vs. 54.1%, χ2=5.355, P=0.021). Patients in the two groups in sex, first diagnosis symptoms, intrahepatic bile duct stone history, nail protein, albumin, total bilirubin, transaminase, liver function Child-Pugh grade, T stage, stage, N stage, preoperative laparoscopic exploration proportion, tumor diameter, vascular invasion proportion, differentiation, margin, intraoperative bleeding, postoperative complications, postoperative hospital days were no statistical significance (all P>0.05). Patients in the EOICC group had better outcomes than the LOICC group (median survival time: 29.7 months vs. 25.0 months, 3-year overall survival: 45.1% vs. 37.8%, P=0.027). Conclusion:EOICC patients are better than LOICC patients in carcinoembryonic antigen, CA19-9, ALT, physical strength status and TNM stage, and the long-term prognosis is also better than LOICC patients.

Objective:To explore the clinical characteristics of biliary system diseases complicated by severe acute pancreatitis(SAP) and the risk factors.Methods:This is a retrospective cohort study. A retrospective analysis was conducted on the clinical data of 159 SAP patients admitted to the Department of Pancreatic and Biliary Surgery,the First Affiliated Hospital of Harbin Medical University from January 2019 to October 2024. There were 105 male cases, 54 female cases;aged (42.3±10.8)years (range:20 to 71 years). Grouping was performed according to the presence or absence of concurrent acute acalculous cholecystitis (AAC) and biliary stricture. There were 58 cases in the AAC group,including 40 males and 18 females;aged (43.8±10.6) years (range:28 to 71 years);101 cases in the non-AAC group,including 64 males and 37 females;aged (41.5±10.8) years (range:20 to 64 years);there were statistically significant differences between the two groups in terms of admission total bilirubin,Balthazar-CTSI score,fasting time,and the proportions of concurrent shock and sepsis (all P<0.05);the time from onset of SAP to diagnosis of AAC( M (IQR)) was 10.5 (13.3) days (range: 3 to 34 days). There were 15 cases in the biliary stricture group,including 13 males and 2 females;age (46.5±10.0) years (range:33 to 63 years);141 cases in the non-biliary stricture group,including 89 males and 52 females;age (41.9±10.8) years (range: 20 to 71 years); there were statistically significant differences between the two groups in the proportions of infected pancreatic necrosis,pancreatic head necrosis,and lower extremity venous thrombosis (all P<0.05);the time from the onset of SAP to the diagnosis of biliary stenosis in patients with biliary stenosis was 2.0 (3.0) months (range: 1 to 19 months). Univariate analysis was performed using independent sample t-test, Mann-Whitney U test, χ 2 test,or Fisher′s exact probability method,and variables with P<0.05 in univariate analysis were included in multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic and predictive value of the multivariate logistic regression model for AAC and biliary stricture. Results:There were statistically significant differences in fasting time,Balthazar-CTSI score,admission total bilirubin,and the proportions of concurrent shock and sepsis between the AAC group and non-AAC group ( P<0.05). Multivariate logistic analysis showed that admission total bilirubin ( OR=1.033,95% CI: 1.010 to 1.058, P=0.004),Balthazar-CTSI score ( OR=1.276,95% CI: 1.036 to 1.572, P=0.022),fasting time ( OR=1.127,95% CI: 1.044 to 1.216, P=0.002), and sepsis ( OR=4.033, 95% CI: 1.419 to 11.462, P=0.009) were independent risk factors for AAC complicated by SAP. The area under the curve (AUC) of the ROC curve was 0.820 (95% CI: 0.752 to 0.888). There were statistically significant differences in the proportions of infected pancreatic necrosis,pancreatic head necrosis,and lower extremity venous thrombosis between the biliary stricture group and non-biliary stricture group ( P<0.05). Multivariate logistic analysis showed that infected pancreatic necrosis ( OR=7.376,95% CI:1.566 to 37.750, P=0.012) and pancreatic head necrosis ( OR=3.898,95% CI:1.180 to 12.877, P=0.026) were independent risk factors for biliary stricture complicated by SAP. The AUC of the ROC curve was 0.806 (95% CI:0.715 to 0.898). Conclusions:AAC typically occurs in the early stage of SAP,and biliary stricture usually occurs in the late stage of SAP. Admission total bilirubin,Balthazar-CTSI score,fasting duration,and concurrent sepsis are independent risk factors for AAC complicating SAP. Infected pancreatic necrosis and pancreatic head necrosis are independent risk factors for biliary stricture complicating SAP.
