Objective: To elucidate the biological basis of traditional Chinese medicine (TCM) syndromes from the perspective of “same syndrome, different diseases” in patients with chronic hepatitis B (CHB), liver cirrhosis (LC), and hepatocellular carcinoma (HCC), thereby providing a complementary approach for the diagnosis and treatment of chronic liver diseases (CLD). Methods: To investigate the dynamic characteristics of TCM syndromes in CLD, transcriptomic profiling of peripheral blood mononuclear cells (PBMCs) was performed from patients with CHB, LC, or HCC presenting with three TCM syndromes: liver gallbladder dampness heat syndrome (LGDHS), liver depression spleen deficiency syndrome (LDSDS), and liver kidney Yin deficiency syndrome (LKYDS). These participants were recruited at Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine between August 1, 2018 and December 31, 2021. Differentially expressed genes (DEGs) were identified using the random variance model (RVM) F test with false discovery rate (FDR) correction. Principal component analysis (PCA) and unsupervised hierarchical clustering were applied to visualize sample grouping. Dynamic network biomarkers (DNB) analysis was employed to detect critical transition stages during syndrome evolution, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses to characterize the functional roles and pathway involvement of the DNB members. Random forest (RF) analysis and the area under the receiver operating characteristic (ROC) curves (AUC) were used to rank the importance of candidate genes. External validation was performed using microarray data from an independent CLD cohort (GSE89377) and RNA-seq data from The Cancer Genome Atlas Liver Hepatocellular Carcinoma (TCGA-LIHC) dataset. Additionally, reverse transcription quantitative polymerase chain reaction (RT-qPCR) was performed on an independent cohort of LC patients to validate the expression levels of the candidate genes. Results: The study included a total of 132 participants. DNB analysis identified LDSDS stage as a critical tipping point during TCM syndrome evolution across CHB, LC, and HCC. The phosphoinositide 3-kinase/protein kinase B (PI3K-AKT) signaling pathway was consistently enriched in the DNB analysis across all three types of CLD, suggesting its potential involvement in the critical transition of TCM syndromes. Among the 24 core DNB members of the PI3K-AKT pathway, four genes—integrin subunit beta 1 (ITGB1), collagen type IV alpha 1 chain (COL4A1), collagen type IV alpha 2 chain (COL4A2), and DNA damage inducible transcript 3 (DDIT3)—were identified by RF analysis (Gini score > 1) and ROC analysis. ROC analysis demonstrated high discriminative ability for distinguishing LGDHS from LKYDS in CHB patients, with AUC of 0.7891 for ITGB1, 0.7070 for COL4A1, 0.7148 for COL4A2, and 0.8945 for DDIT3. In the independent CLD cohort (GSE89377), all four genes showed significant stepwise upregulation from normal to CHB, LC, and HCC (all P < 0.05). In the TCGA-LIHC dataset, their expression progressively increased with tumor stage. RT-qPCR validation in an independent LC cohort (30 LGDHS vs. 30 LKYDS) confirmed that ITGB1, COL4A2, and DDIT3 were significantly upregulated in LKYDS compared with LGDHS (P = 0.0152, 0.0186, and 0.0247, respectively), whereas COL4A1 showed a non-significant upward trend (P = 0.1201). Conclusion This study introduces a novel approach to understanding the molecular features underlying TCM syndrome evolution in CLD. The PI3K-AKT pathway and four identified genes (ITGB1, COL4A1, COL4A2, and DDIT3) play crucial roles in the transition from excess (LGDHS) to deficiency (LKYDS) via the critical LDSDS stage. These findings offer potential quantitative biomarkers and therapeutic targets for TCM syndrome differentiation and may help arrest syndrome progression in CLD.

Objective:To establish a normal data model of fetal right ventricular size and function using echocardiography，and to explore the clinical value of quantitative assessment of right ventricular size and function in the diagnosis of congenital heart diseases.Methods:（1）A simple random sampling method was employed to collect 1 004 pregnant women with normal singleton pregnancies at 24 to 32 +6 weeks of gestation who underwent fetal cardiac ultrasound examinations at the First Affiliated Hospital of Air Force Medical University from January 2021 to December 2023. Two-dimensional and M-mode echocardiography were used to measure the right ventricular end-diastolic diameter（RVEDD），right ventricular end-diastolic area（RVEDA），tricuspid annular plane systolic excursion（TAPSE）during systole，and the right ventricular fractional area change（RVFAC）was calculated. The correlations between the above parameters and ultrasound gestational age（USGA）were analyzed. Moreover，percentile growth curves for each parameter were plotted. With the above parameters as dependent variables and the USGA as the independent variable，a Z-score model was established through regression analysis.（2）A stratified sampling method was adopted to select 30 fetuses diagnosed with hypoplastic right heart syndrome（HRHS）and 30 fetuses diagnosed with pulmonary stenosis（PS）during the same period as the case group. The model was verified，and the morphological and functional characteristics of the right ventricle were analyzed. Results:The data of RVEDD，RVEDA，TAPSE，and RVFAC in normal fetuses showed a skewed distribution. Each parameter showed good linear correlations with USGA（ r=0.836，0.834，0.846，0.242；all P<0.001）. The constructed percentile curves for each parameter indicated that RVEDD，RVEDA and TAPSE increased significantly with the growth of USGA，while RVFAC showed a slow downward trend. All parameters in the HRHS group and TAPSE and RVFAC in the PS group deviated significantly from the normal reference range（all P<0.001）. Conclusions:By analyzing RVEDD，RVEDA，TAPSE and RVFAC of normal fetuses，the percentile and Z-score normal reference value models of multiple parameters of fetal right ventricular size and function have been established，providing corresponding standards for quantitative analysis.

The ultimate treatment goal of periodontitis is the structural and functional regeneration of periodontium. However, existing methods for periodontal regeneration have difficulties in regenerating the hierarchical structure. Therefore, stem cell-based tissue engineering has attracted more and more attention for its advantages of self-renewal and multi-lineage differentiation potential. This review summarized the progress of research on periodontal tissue regeneration by combined biomaterials of dental-derived stem cells. It is pointed out that the application of autologous stem cell transplantation is limited by the donor source, and the subsequent research should focus on the development of multi-phase scaffold materials and the attempt to establish a stem cell bank.

Purpose: We aimed to evaluate whether the addition of pemetrexed is effective in improving progression-free survival (PFS) in epidermal growth factor receptor (EGFR)–mutated patients with or without concomitant alterations. Materials and Methods: This multicenter clinical trial was conducted in China from June 15, 2018, to May 31, 2019. A total of 92 non–small cell lung cancer (NSCLC) patients harboring EGFR-sensitive mutations were included and divided into concomitant and non-concomitant groups. Patients in each group were randomly treated with EGFR–tyrosine kinase inhibitor (TKI) monotherapy or EGFR-TKI combined with pemetrexed in a ratio of 1:1. PFS was recorded as the primary endpoint. Results: The overall median PFS of this cohort was 10.1 months. There were no significant differences in PFS between patients with and without concomitant and between patients received TKI monotherapy and TKI combined with pemetrexed (p=0.210 and p=0.085, respectively). Stratification analysis indicated that patients received TKI monotherapy had a significantly longer PFS in non-concomitant group than that in concomitant group (p=0.002). In concomitant group, patients received TKI combined with pemetrexed had a significantly longer PFS than patients received TKI monotherapy (p=0.013). Molecular dynamic analysis showed rapidly emerging EGFR T790M in patients received TKI monotherapy. EGFR mutation abundance decreased in patients received TKI combined chemotherapy, which supports better efficacy for a TKI combined chemotherapy as compared to TKI monotherapy. A good correlation between therapeutic efficacy and a change in circulating tumor DNA (ctDNA) status was found in 66% of patients, supporting the guiding role of ctDNA minimal residual disease (MRD) in NSCLC treatment. Conclusion EGFR-TKI monotherapy is applicable to EGFR-sensitive patients without concomitant alterations, while a TKI combined chemotherapy is applicable to EGFR-sensitive patients with concomitant alterations. CtDNA MRD may be a potential biomarker for predicting therapeutic efficacy.

Objective:To investigate the correlation of c-MET expression with circulating miR-34a and miR-449 level in pancreatic cancer tissue and its clinical significance.Methods:A total of 41 patients with pancreatic cancer treated surgically and pathologically confirmed from March 2015 to March 2017 were collected in Second Affiliated Hospital of Jiaxing Medical College. The expression of hepatocyte growth factor receptor (c-MET) in pathological tissues and matching adjacent normal tissues was determined by immunohistochemistry. The patients were divided into c-MET positive group ( n=26) and c-MET negative group ( n=15) according to the results. Peripheral blood was collected before and 3 months after the operation, and the expressions of circulating miRNA34a (miR-34a) and miR-449 were determined by fluorescence quantitative PCR. The relationships between c-MET in pancreatic cancer tissue and clinicopathological features, prognosis, circulating miR-34a expression, and miR-449 expression were analyzed. The effects of circulating miR-34a and miR-449 expression on TNM stage, lymph node metastasis and prognosis of pancreatic cancer patients were analyzed. Results:The positive rate of c-MET in pancreatic cancer was obviously higher than that in adjacent normal tissue (63.4% vs 24.4%), and the difference was statistically significant ( P<0.05). Compared with c-MET negative group, the TNM stage Ⅲ/Ⅳ cases in c-MET positive group were more (73.1% vs 33.4%), the lymph node metastasis rate in c-MET positive group (76.9% vs 46.7%) were higher, and the follow-up survival time of c-MET positive group was shorter (29.5 mo vs 35 mo), and the survival rate of the c-MET positive group was lower (38.5% vs 53.3%), and the differences were statistically significant (all P<0.05). Before surgery, the expressions of circulating miR-34a and miR-449 in the c-MET positive group were lower than those in the c-MET negative group (0.228±0.068 vs 0.524±0.106, 0.252± 0.063 vs 0.432±0.094, P<0.05). After surgery, the miR-449 expression in c-MET positive group was still lower than that in c-MET negative group (0.414±0.088 vs 0.512±0.114, P<0.05), while there was no statistically significant difference on miR-34a between the two groups. Preoperative miR-34a and miR-449 expression had predictive value for TNM stage, lymphatic metastasis and prognosis ( P<0.05). Conclusions:miR-34a and miR-449 may target c-MET in pancreatic cancer tissue, which could be used as potential tumor markers for pancreatic cancer.

Objective To study changes of serum IL-17 and IL-35 levels in patients with heart failure. Methods 60 patients with heart failure (observation group)were selected as research subjects.60 patients accord-ing to different severity were divided into acute period heart failure (34 cases)and stable stage heart failure (26 ca-ses);60 patients graded according to the NYHA standards were divided into 24 cases of heart failure with grade Ⅱ, 20 cases of grade Ⅲ ,16 cases of grade Ⅳ.According to the different primary diseases :expansion cardiomyopathy group (20 cases in group A),the coronary heart disease group (group B,24 cases),hypertensive heart disease group (group C,16 cases).During the same period,42 healthy elderly people in our hospital were selected as control group. The serum IL-17,IL-35 levels were tested,and the serum IL-17,IL-35 levels in patients with heart failure were ana-lyzed.Results Serum level of IL-17 in the observation group was higher than the control group,and the difference was significant [(15.61 ±4.02)pg/mL vs (9.49 ±3.96)pg/mL,t =9.018,P <0.01].Serum level of IL-35 in the observation group was significantly lower than that of the control group,and the difference was significant[(52.78 ± 4.29)pg/mL vs (61.49 ±4.81)pg/mL,t =11.963,P <0.01].The level of serum IL-17 in acute stage of patients with heart failure was higher than that of stable heart failure,and the difference was significant (t =6.278,P <0.01);IL-35 level in serum of patients with heart failure in acute phase was lower than that of stable heart failure,the difference was significant (t =9.529,P <0.01).With the increase in heart failure grade,serum IL-17 level showed a rising trend,and the differences among three groups had statistical differences (F =6.098,P <0.01);serum IL-35 level decreased,and the differences among three groups had statistical differences(F =8.978,P <0.01).The serum IL-17 level of A group was higher than that in B group and C group,there were significant differences (F =6.096, P <0.01),the serum IL-17 level between B group and C group had no statistical difference (t =0.172,P >0.05). The serum IL-35 level of A group was lower than that of B group and C group,there were significant differences (F =8.978,P <0.01),the serum IL-35 level between B group and C group had no statistical difference (t =0.208,P >0.05).Serum IL-17 and serum IL-35 level was negatively correlated (r =-0.429,P =0.009).Conclusion High expression of IL-17 in elderly patients with heart failure,while IL-35 decreased in elderly patients with heart failure, IL-17,IL-35 are closely related to the senile congestive heart failure and the severity of illness.Serum IL-17 is nega-tively correlated with the level of serum IL-35.

Objective To develop and apply an ICU orientation program based on the Miller pyramid competency model. Methods 45 new ICU nurses in 2013 and 2014 were selected as the experimental group. The experimental group was oriented by the new program,including the orientation of preceptors, workshop-centered orientation courses, checklists-precepting and comprehensive competency evaluation methods. 39 new ICU nurses in 2011 and 2012 were selected as the control group. The control group was oriented by the conventional program,including focused theory classes and traditional precepting.New nurses′ satisfaction with the orientation and the competency were analyzed before and after intervention in two groups. Results Satisfaction with the orientation, self-evaluated competency and peer-evaluated competency in the experimental group were(16.71±1.19) scores, (126.52±3.31) scores and (90.00±2.68) scores respectively,which were much better than the control group and had statistically significant difference in two groups. Conclusions The ICU new nurse orientation program based on the Miller pyramid competency model can improve the new nurses′ satisfaction with the orientation and the competency after the orientation.
