Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Poor water solubility is the primary obstacle preventing the development of many pharmacologically active compounds into oral preparations. Self-nanoemulsifying drug delivery systems(SNEDDS) have become a widely used strategy to enhance the oral bioavailability of poorly soluble drugs by inducing a supersaturated state, thereby improving their apparent solubility and dissolution rate. However, the supersaturated solutions formed in SNEDDS are thermodynamically unstable systems with solubility levels exceeding the crystalline equilibrium solubility, making them prone to drug precipitation in the gastrointestinal tract and ultimately hindering drug absorption. Therefore, maintaining a stable supersaturated state is crucial for the effective delivery of poorly soluble drugs. Incorporating polymers as precipitation inhibitors(PPIs) into the formulation of supersaturated self-nanoemulsifying drug delivery systems(S-SNEDDS) can inhibit drug aggregation and crystallization, thus maintaining a stable supersaturated state. This has emerged as a novel preparation strategy and a key focus in SNEDDS research. This review explores the preparation design of SNEDDS and the technical challenges involved, with a particular focus on polymer-based S-SNEDDS for enhancing the solubility and oral bioavailability of poorly soluble drugs. It further elucidates the mechanisms by which polymers participate in transmembrane transport, summarizes the principles by which polymers sustain a supersaturated state, and discusses strategies for enhancing drug absorption. Altogether, this review provides a structured framework for the development of S-SNEDDS preparations with stable quality and reduced development risk, and offers a theoretical reference for the application of S-SNEDDS technology in improving the oral bioavailability of poorly soluble drugs.

Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

Objective:To investigate the feasibility and safety of intracardiac echocardiography(ICE)combined with total three-dimensional(T3D)technique in zero-fluoroscopy individualized transseptal puncture.Methods:A total of 112 patients with atrial fibrillation who underwent radiofrequency ablation in Yongchuan Hospital Affiliated to Chongqing Medical University from April 2021 to March 2024 were enrolled,and according to the method for transseptal puncture,they were randomly divided into ICE+T3D group with 56 patients and ICE group with 56 patients.The two groups were analyzed in terms of baseline data,time to atrial reconstruc-tion,time to coronary sinus electrode placement,frequency of ICE probe adjustment during transseptal puncture,duration of transsep-tal puncture,pretreatment time before ablation,incidence rate of complications,and the duration and dosage of X-ray exposure.Results:There were no significant differences in baseline data between the two groups.Compared with the ICE group,the ICE+T3D group had a significantly lower frequency of ICE probe adjustment during transseptal puncture(1.70±0.63 vs.5.34±1.71,P<0.001)and the duration of transseptal puncture(3.66±1.09 min vs.4.90±1.92 min,P<0.001).Compared with the ICE group,the ICE+T3D group had significantly longer time to atrial reconstruction(22.44±3.13 min vs.12.34±2.12 min,P<0.001)and pretreatment time be-fore ablation(49.41±3.52 min vs.37.65±4.04 min,P<0.001).In the ICE+T3D group,43(76.8%)patients achieved zero radiation during pretreatment before ablation,and 13 patients received X-ray due to the difficulty in catheter placement;compared with the ICE group,the ICE+T3D group had a significantly shorter duration of X-ray exposure(1.68±0.72 min vs.3.14±1.95 min,P=0.010)and a significantly lower dosage of X-ray exposure(6.28±2.78 mGy vs.23.85±21.32 mGy,P=0.004).During the stage of transseptal punc-ture,all patients in the ICE+T3D group achieved zero radiation,while 45 patients(80.4%)in the ICE patients received X-ray.In terms of complications,there were no life-threatening complications such as cardiac tamponade,perforation of the aorta by mistake,and embolization in either group,while there was one case(1.8%)of vascular complications in each group.Conclusions:ICE combined with T3D after integration and improvement is a safe and reliable procedure for zero-fluoroscopy individualized transseptal puncture.

Objective To investigate the inhibitory effect of erianin on T cell proliferation and its underlying mechanism.Methods Peripheral blood mononuclear cells(PBMCs)were isolated using density gradient centrifugation,and T cells were purified by magnetic-activated cell sorting(MACS)with immunomagnetic beads,followed by being activated with anti-human CD3 antibodies and anti-human CD28 antibodies.The activated T cells were labeled with carboxyfluorescein succinimidyl ester(CFSE),and the effects of erianin(0.05～0.20 μmol/L)on the proliferation,apoptosis,expression of activation marker cluster of differentiation 25(CD25),cell cycle distribution of activated T cells,as well as the survival rate of resting T cells were assessed using flow cytometry.Enzyme-linked immunosorbent assay(ELISA)was applied to determine the secretion levels of IL-2 and IL-17 in the culture supernatant of erianin-treated activated T cells.Western blotting was employed to examine the impact of erianin on the protein expression of cell division cycle protein 2(CDC2),phosphorylated CDC2(p-CDC2),and Cyclin B1.The differences were observed between the erianin-treated group and the positive control group(activation with CD3/CD28 antibodies).Results CFSE proliferation assay demonstrated that the proliferative rate of activated T cells was in a concentration-dependent decline after 0.05～0.20 μmol/L erianin treatment(P<0.0001),with a half-maximal inhibitory concentration(IC50)of 0.09±0.10 μmol/L.No significant differences were observed in apoptotic rates or survival rates among the erianin-treated groups(activated and resting T cells)and the positive control cells.Analysis of T cell activation markers revealed that erianin had no impact on CD25 expression or IL-2 secretion.However,ELISA results indicated erianin exerted a significant suppression on the secretion of pro-inflammatory cytokine IL-17(P<0.0001).Cell cycle analysis showed that erianin arrested activated T cells at the G2/M phase(P<0.05).Further mechanistic investigations demonstrated that while erianin did not alter CDC2 phosphorylation or total CDC2 expression,but it markedly down-regulated CyclinB1 expression(P<0.01).Conclusion Erianin exhibits potent immunomodulatory activity by suppressing activated T cell proliferation through down-regulating Cyclin B1.

Objective To study the infection of multidrug-resistant organism(MDRO)in elderly pa-tients with catheter-associated urinary tract infection(CAUTI)and analyze the infection factors.Methods The medi-cal records of 175 elderly patients with CAUTI admitted to Jiangsu Province Hospital from January 2021 to July 2022 were selected,the distribution of MDRO infection in elderly patients with CAUTI was analyzed,and the influencing factors of MDRO infection were analyzed.The predictive value of independent risk factors for rele-vant nosocomial infections was analyzed by receiver operating characteristics(ROC)curves.Results Among the 175 elderly patients with CAUTI,87 cases(49.71％)developed MDRO infection and were included in the MDRO infection group),and 88 cases(50.29％)had no MDRO infection and were included in the non-MDRO infection group.A total of 432 MDRO pathogens were detected in the MDRO infection group,inclu-ding 415 strains of Gram-negative bacteria,accounting for 96.06％,186 strains of carbapenem-resistant Acine-tobacter baumannii(43.06％),147 strains of carbapenem-resistant Klebsiella pneumoniae(34.03％),79 strains of carbapenem-resistant Pseudomonas aeruginosa(18.29％)and 3 strains of carbapenem-resistant Escherichia coli(0.69％).There were 17 strains of Gram-positive bacteria(3.94％),all of which were methi-cillin-resistant Staphylococcus aureus.Multivariate analysis showed that the use of carbapenems,tigecycline,polymyxin,and days of central venous intubation were considered as independent risk factors.The area under the curve of MDRO infection was 0.883.Conclusion For elderly patients with CAUTI,it is necessary to take strict antimicrobial management measures,master the indications of antimicrobial application,shorten the hos-pitalization time of patients and reduce the incidence of MDRO infection.

Objective:To investigate the safety,efficacy,and prognosis of high-dose melphalan in combination with autologous hematopoietic stem cell transplantation (ASCT) for the treatment of multiple myeloma (MM). Methods:The clinical data of 17 patients with newly diagnosed MM who underwent ASCT as first-line consolidation therapy at the Yijishan Hospital of Wannan Medical College from March 2020 to October 2022 were retrospectively analyzed. The safety,efficacy,and prognosis of this treatment approach were evaluated. Results:Of the 17 patients,10 were male and 7 were female,with a median age of 56 (45-64) years. The stem cell engraftment rate was 100％,with a median neutrophil engraftment time of+10 (9-12) days and a median platelet engraftment time of+12 (10-21) days. The incidence of oral mucositis and intestinal infection after transplantation was 100％,with 2 cases of pulmonary infection,1 case of urinary tract infection,1 case of skin infection,and 11 cases of transient elevation of serum amylase. After transplantation,13 patients achieved a complete response (CR) or better,and the CR rate showed an increasing trend compared to before transplantation (13/17 vs 8/17;P=0.078). The median follow-up time was 18 (6-36) months,and 15 patients survived without progression,1 patient experienced disease progression,and 1 patient died due to clinical relapse and abandonment of treatment. The 2-year overall survival (OS) rate and progression-free survival (PFS) rate were approximately 90.0％ and 83.9％,respectively. Conclusion:High-dose melphalan in combination with ASCT as first-line consolidation therapy for MM can enhance the depth of patient response,further improve therapeutic efficacy,and the transplant-related complications are controllable,making it a viable option worth promoting in clinical practice.

Objective:To explore expression and prognostic value of oncostatin M(OSM)in endometrial cancer and to analyze relationship between OSM expression and immune cell infiltration in endometrial cancer tissues.Methods:OSM expression in pan-can-cer was analyzed by TIMER database,OSM expression in endometrial cancer and normal tissues was compared,and survival analysis for patients with different OSM expression was performed;relationship between OSM expression and immune cell infiltration was analyzed by TIMER and TISIDB,and ssGSEA algorithm was used to calculate difference in abundance of immune cell infiltration in samples with different OSM expression;GSEA software was applied to perform enrichment analysis;clinical tissue samples were collected for validation.Results:OSM expression was higher in endometrial cancer tissues than that in normal endometrial tissues(P=4.1e-28),and endometrial cancer patients with high OSM expression had prolonged recurrence-free survival(RFS)(P=0.004 8).OSM expression was positively correlated with abundance of immune cell infiltration and genetic markers of immune cells(P<0.05).OSM was mainly enriched in immune-related signaling pathways.OSM expression was higher in endometrial cancer tissues than normal and atypical hyperplastic tissues(P=0.016 9).Proportions of immune cell markers CD4,CD8,and CD68 were increased in tumor tissues with high OSM expression(all P<0.05),which were positively correlated with OSM expression.Conclusion:OSM is highly expressed in endometrial cancer tissues and correlated with prognosis;OSM expression is positively correlated with immune cell infiltration level and can be used as a biomarker for immunotherapy and prognosis.

Purpose: Patients with advanced biliary tract cancer (BTC) have a poor survival. We aim to evaluate the efficacy and safety of nab-paclitaxel plus gemcitabine and cisplatin regimen in Chinese advanced BTC patients. Materials and Methods: Eligible patients with locally advanced or metastatic BTC administrated intravenous 100 mg/m2 nab-paclitaxel, 800 mg/m2 gemcitabine, and 25 mg/m2 cisplatin every 3 weeks. The primary endpoint was progression-free survival (PFS). The secondary endpoints included overall survival (OS) and adverse events, while exploratory endpoint was the association of biomarkers with efficacy. Results: After the median follow-up of 25.0 months, the median PFS and OS of 34 enrolled patients were 7.1 months (95% confidence interval [CI], 5.4 to 13.7) and 16.4 months (95% CI, 10.9 to 23.6), respectively. The most common treatment-related adverse events at ≥ 3 grade were neutropenia (26.5%) and leukopenia (26.5%). Survival analyses demonstrated that carcinoembryonic antigen (CEA) levels could monitor patients’ survival outcomes. A significant increase in the number of infiltrating CD4+ cells (p=0.008) and a decrease in programmed death-1–positive (PD-1+) cells (p=0.032) were observed in the response patients. Conclusion In advanced BTC patients, nab-paclitaxel plus gemcitabine and cisplatin regimen showed therapeutic potential. Potential prognostic factors of CEA levels, number of CD4+ cells and PD-1+ cells may help us maximize the efficacy benefit.
