ObjectiveTo explore the potential mechanism of Shenqi Jianxin Formula （参芪健心方） in the treatment of chronic heart failure （CHF） from the perspective of regulating mitochondrial autophagy via the PTEN-induced kinase 1 （PINK1）/E3 ubiquitin ligase （Parkin） pathway. MethodsMale SD rats were subjected to abdominal aortic constriction to establish the CHF model. Twenty-four successfully modeled rats were randomly divided into the model group， sacubitril/valsartan group， and low- and high-dose Shenqi Jianxin Formula groups， with 6 rats in each group. Six other rats were set as the sham surgery group， which were only separated the abdominal aorta and then closed the abdomen. Rats in the low-dose and high-dose Shenqi Jianxin Formula groups were given intragastric administration of Shenqi Jianxin Formula suspension at doses of 4.41 g/（kg·d） and 17.64 g/（kg·d）， respectively； the sacubitril/valsartan group received intragastric administration of sacubitril/valsartan sodium tablet suspension at 10 mg/（kg·d）； the sham surgery group and the model group were given normal saline at 10 ml/（kg·d） via intragastric gavage. The intervention lasted for 4 consecutive weeks. Cardiac function indices including left ventricular ejection fraction （LVEF） and left ventricular fractional shortening （LVFS） were detected， and serum brain natriuretic peptide （BNP） content was measured. HE staining and Masson staining were used to observe myocardial histopathological changes. Transmission electron microscopy was employed to examine the ultrastructure of cardiac tissues. Quantitative real-time polymerase chain reaction （Rt-qPCR） was performed to determine the mRNA expressions of PINK1/Parkin pathway-related factors and autophagy-associated proteins including Beclin-1， p62， and microtubule-associated protein 1 light chain 3 （LC3） in myocardial tissues. ResultsCompared with the sham surgery group， the model group showed significant decreases in LVEF and LVFS levels， an increase in serum BNP content， down-regulated mRNA and protein expressions of PINK1， Parkin and Beclin-1 in cardiac tissues， up-regulated mRNA and protein expressions of p62， as well as significant reductions in LC3B mRNA expression， phosphorylated PTEN-induced kinase 1 （p-PINK1） and phosphorylated E3 ubiquitin ligase （p-Parkin） protein levels， and the ratio of microtubule-associated protein 1 light chain 3-Ⅱ to microtubule-associated protein 1 light chain 3-Ⅰ （LC3Ⅱ/LC3Ⅰ） （P＜0.05）. Pathological results revealed obvious myocardial cell edema， necrosis and degeneration， increased disorder of myocardial fiber arrangement， extensive inflammatory cell infiltration， moderate to severe mitochondrial swelling， a few mitochondrial vacuolar changes， and no obvious autophagy in the field of vision in the model group. Compared with the model group， all the above indicators were significantly improved in the high-dose Shenqi Jianxin Formula group and the sacubitril/valsartan group （P＜0.05）. Moreover， the improvement of each index in the high-dose Shenqi Jianxin Formula group was superior to that in the low-dose group （P＜0.05）. In the high-dose Shenqi Jianxin Formula group， myocardial myofibrils were arranged regularly with orderly orientation， the striated structure was clear， and necrotic cells significantly reduced. ConclusionShenqi Jianxin Formula can activate the PINK1/Parkin signaling pathway in myocardial tissues， enhance mitochondrial autophagy， and clear dysfunctional mitochondria， thereby improving cardiac function and delaying the progression of CHF.

Based on the concept of "blood exhaustion" from The Inner Canon of Yellow Emperor （《黄帝内经》）， a three-stage syndrome differentiation and treatment strategy for cancer-related anorexia-cachexia syndrome is proposeed. In the cancer-induced anorexia stage， the pathogenesis is characterized by cancer consuming the spleen and stomach， leading to stagnation of transportation and transformation in the middle jiao （焦）. Treatment should focus on strengthening the spleen， promoting appetite， dispersing accumulation， and aiding digestion， with modified Zisheng Pills （资生丸） in Extensive Notes on Medicine from Xian Xing Studio （《先醒斋医学广笔记》） or Zisheng Decoction （资生汤） in Records of Chinese Medicine with Reference to Western Medicine （《医学衷中参西录》）. In the pre-cachectic stage of malnutrition， the pathogenesis involves insufficient nourishment of blood and qi with essence depletion hindering production. Treatment should focus on nourishing blood and harmonizing ying （营）， warming yang and supplementing qi， and modified Huangqi Jianzhong Decoction （黄芪建中汤） can be used. In the cachectic stage， the pathogenesis involves blood deficiency and essence exhaustion， with blood stasis obstructing the collaterals. The therapeutic approach should focus on tonifying deficiency and replenishing essence， unblocking collaterals， and removing stasis， and modified Buzhong Yiqi Decoction （补中益气汤） and Zuo Gui Beverage （左归饮） are suggested.

The transition of cancer cells from epithelial state to mesenchymal state awarded hepatocellular carcinoma (HCC) stem cell properties and induced tumorigenicity, drug resistance, and high recurrence rate. Reversing the mesenchymal state to epithelial state by inducing mesenchymal-epithelial remodeling could inhibit the progression of HCC. Using high-throughput screening, chrysin was selected from natural products to reverse epithelial-mesenchymal transition (EMT) by selectively increasing CDH1 expression. The target identification suggested chrysin exerted its anti-HCC effect through covalently and specifically binding threonine 205 (Thr205) of alpha-enolase (ENO1). For the first time, we revealed that ENO1 bound β-catenin mRNA, and recruited YTHDF2 to identify the m6A modified β-catenin in the 3'-UTR region to degrade β-catenin mRNA. Eventually, the CDH1 gene expression was improved through the regulation of β-catenin mRNA. ENO1/β-catenin mRNA interaction might be a promising target for cellular plasticity reprogramming. Moreover, chrysin could mediate mesenchymal‒epithelial remodeling through increasing degradation of β-catenin mRNA by promoting the binding of ENO1 and β-catenin mRNA. To the best of our knowledge, chrysin is the first reported small molecule inducing β-catenin mRNA degradation through binding to ENO1. The water-soluble derivative of chrysin may be a natural product-derived lead compound for circumventing metastasis, recurrence, and drug resistance of HCC by mediating mesenchymal‒epithelial remodeling.

OBJECTIVE: To develop a digital intelligent multimodal shift handover system for the intensive care unit (ICU) and evaluate its application effect in ICU shift handovers. METHODS: A research and development team was established, consisting of 1 department director, 1 head nurse, 3 information technology engineers, 3 nurses, and 2 doctors. Team members were assigned responsibilities including overall coordination and planning, platform design and maintenance, pre-application training, collection and organization of clinical feedback, and research investigation respectively. A digital intelligent multimodal shift handover system was developed for ICU based on the Shannon-Weaver linear transmission model. This innovative system integrated automated data collection, intelligent dynamic monitoring, multidimensional condition analysis and visual reporting functions. A cloud platform was used to gather data from multi-parameter vital signs monitors, infusion pumps, ventilators and other devices. Artificial intelligence algorithms were employed to standardize and analyze the data, providing personalized recommendations for healthcare professionals. A self-controlled before-after method was adopted. Before the application of the ICU digital intelligent multimodal shift handover system (from December 2023 to March 2024), the traditional verbal bedside handover was used; from June 2024 to March 2025, the ICU digital intelligent multimodal shift handover system was applied for shift handovers. Questionnaires before the application of the shift handover system were collected in April 2024, and those after the application were collected in April 2025. The shift handover time, handover quality (scored by the nursing handover evaluation scale), satisfaction with doctor-nurse communication (scored by the ICU doctor-nurse scale) before and after the application of the handover system were compared, and nurses' satisfaction with the shift handover system (scored by the clinical nursing information system effectiveness evaluation scale) was investigated. RESULTS: After the application of the ICU digital intelligent multimodal shift handover system, the shift handover time was significantly shorter than that before the application [minutes: 20 (15, 25) vs. 30 (22, 40)], the handover quality was significantly higher than that before the application [score: 84.0 (78.0, 88.5) vs. 71.0 (55.0, 79.0)], and the satisfaction with doctor-nurse communication was also significantly higher than that before the application (score: 84.58±6.79 vs. 74.50±11.30). All differences were statistically significant (all P < 0.05). In addition, the nurses' system effectiveness evaluation scale score was 102.30±10.56, which indicated that nurses had a very high level of satisfaction with the ICU digital intelligent multimodal shift handover system. CONCLUSIONS The application of the ICU digital intelligent multimodal shift handover system can shorten the shift handover time, improve the handover quality, and enhance the satisfaction with doctor-nurse communication. Nurses have a high level of satisfaction with this system.

Objective:To evaluate the safety and effectiveness of fuzuloparib for the treatment of ovarian epithelial cancer patients in the real world setting.Methods:A retrospective analysis was conducted on the baseline data of 4 620 ovarian cancer patients who had received fuzuloparib monotherapy or combination therapy. Another 224 ovarian cancer patients who were willing to receive fuzuloparib monotherapy or combination therapy were prospectively enrolled, and their baseline characteristics, drug effectiveness, and safety data were analyzed.Results:(1) Among the 4 620 patients in the retrospective cohort, the median age of patients was 60 years; tumor types: 89.8% (4 149/4 620) had ovarian cancer. Among patients with clearly documented information, the vast majority had a histological type of serous carcinoma (82.9%, 3 770/4 546) and International Federation of Gynecology and Obstetrics (FIGO) staging of Ⅲ-Ⅳ (90.9%, 1 537/1 691). (2) Among the 224 patients in the prospective cohort, the median age of patients was 57 years; tumor types: 83.9% (188/224) had ovarian cancer. Among patients with clearly documented records, the predominant pathologic type was serous carcinoma (91.9%, 193/210), and FIGO stage was Ⅲ-Ⅳ in 79.9% (139/174). (3) Among the 224 prospective patients: 84 patients received first-line fluzoparib maintenance therapy, 92 patients received fluzoparib maintenance therapy after platinum-sensitive recurrence, 23 patients received direct fluzoparib treatment after platinum-sensitive recurrence, 19 patients received direct fluzoparib treatment after platinum-resistant recurrence. The median follow-up durations were 8.5, 8.7, 7.9, and 6.7 months, respectively. The median durations of fluzoparib treatment were 6.7, 4.8, 3.1, and 1.9 months, respectively. The median progression-free survival (PFS) times were not reached during follow-up, 12.6 months, not reached during follow-up, and 4.8 months, respectively. The 1-year PFS rates were 84.1%, 55.0%, 69.8%, and 45.5%, respectively. The remaining 6 patients received other fluzoparib regimens. (4) Among the 224 patients in the prospective dataset, 205 had safety data recorded. Of these, 127 patients (62.0%, 127/205) experienced treatment-related adverse events, with common events including anemia (24.4%, 50/205), thrombocytopenia (21.0%, 43/205), and leukopenia (19.5%, 40/205). Among the 205 patients, 43 (21.0%, 43/205) experienced grade 3 or higher treatment-related adverse events, with common events including anemia (8.3%, 17/205) and thrombocytopenia (8.3%, 17/205).Conclusions:The effectiveness of fuzuloparib in clinical application is generally consistent with other drugs in the same class, with good safety. This study provids new clinical evidence for the treatment of ovarian cancer with fuzuloparib.

Objective:To explore the preliminary results of using the UreteroPyeloVisClear Catheter (VCC) in the treatment of ureteral stones.Methods:A retrospective analysis was conducted on the clinical data of 18 patients with ureteral stones who underwent treatment with VCC at Beijing Tsinghua Changgung Hospital from November 2023 to March 2024. The cohort consisted of 15 men and 3 women, with a mean age of 53 years (range: 27-75 years). The preoperative CT measurements showed that the mean maximum stone diameter was 9 mm (range: 3-18 mm), and the mean maximum CT value of the stones was 870 HU (range: 260-1 480 HU). The distribution of stones was as follows: 3 cases in the upper ureter, 8 in the middle ureter, and 7 in the lower ureter. Gravity-assisted perfusion was used, and all patients underwent VCC combined with Holmium laser lithotripsy, with flexible ureteroscopy used if necessary. A ureteral stent was routinely placed for 2 weeks postoperatively. Perioperative conditions and complications were analyzed.Results:All 18 patients successfully underwent VCC lithotripsy, with one patient experiencing stone migration during the procedure. The average operation time was 53 minutes (range: 20-100 minutes), and the average lithotripsy time was 25.5 minutes (range: 6–60 minutes). There were no significant changes in serum creatinine or hemoglobin levels on the first postoperative day. The average hospital stay was 2 days (range: 1–3 days). One patient experienced a fever (maximum temperature of 38.5℃), which resolved with antibiotic treatment. The visual analogue scale (VAS) scores on postoperative day 1 were 0 for 15 patients, 2 for 1 patient, 3 for 1 patient, and 4 for 1 patient. No complications of Clavien-Dindo grade Ⅱ or higher were observed. At 1-month follow-up, the stone-free rate (SFR) was 100%(18/18), and no hydronephrosis was observed in the affected kidney.Conclusions:The results of this study indicates that VCC is a safe and effective method for treating ureteral stones, with a low incidence of postoperative complications and a high stone clearance rate.

Objective:To analyze the current status, identify existing issues, and explore countermeasures for the development of " Six-Good" retirement Party branches in medical institutions and scientific research institutes.Methods:In August 2024, ten medical and research institutions were selected. Focusing on the current status and existing issues in Party branch building for retired personnel, questionnaire surveys were conducted among staff members of the Party office and the retired cadres department, as well as retired Party members. Experts in the field of Party building were selected for semi-structured interviews. Core themes were then extracted through content analysis.Results:The questionnaire survey included a total of 399 survey respondents, comprising 112 staff members from the Party office and the retired cadres department, as well as 287 retired Party members. 212 (53.1%) of the respondents belonged to Party branches with over 50 members, 280 (70.2%) of the respondents expressed a preference for establishing Party branches based on similar business functions or former departments prior to retirement. 373 (93.5%) of the respondents believed Party branch committee members were adequately appointed. 33.7% (127/377) of the respondents perceived ideological fluctuations among retirement Party members. 175 (43.9%) of the respondents indicated that learning content was insufficiently diverse. Through interviews with 15 experts, it was found that the construction of retired party branches was faced with issues such as low participation in offline organizational life, insufficient effectiveness in the education and management of party members, limited role play of party members, and prominent service and support pressures. In response, the experts proposed specific suggestions such as innovating organizational forms, strengthening the effectiveness of education and management, and building platforms for role play.Conclusions:The " Six-Good" Party branch building for retired personnel of the medical and scientific research institutions had achieved certain results, but there were also some problems. It is necessary to further optimize organizational settings, strengthen the branch leadership, innovate learning forms, build a platform for role play, strictly implement various systems, and strengthen assistance to difficult party members.
