Purpose: This study aimed to evaluate the safety and efficacy of gemcitabine and cisplatin (GP) regimen in combination with immune checkpoint inhibitor sintilimab as neoadjuvant therapy for muscle-invasive bladder cancer (MIBC) patients and the feasibility of the following selective bladder sparing surgery. Materials and Methods: Patients with histopathologically confirmed urothelial carcinoma without distant metastases (T2-4a, N ≤ 1, M0, American Joint Committee of Cancer 8th) and with adequate organ function will be enrolled. The therapeutic regimen was sintilimab 200 mg once on day 8, gemcitabine 1,000 mg/m2 and cisplatin 35 mg/m2 once on days 1 and 8, every 21 days for four cycles. The primary endpoint was pathologic complete response (pCR, pT0N0) rate. The secondary end points were ypT < 2 rate, R0 resection rate, event-free survival, and safety. Results: From May 4, 2020, to May 20, 2023, 55 patients were enrolled. Forty-six patients were evaluated for efficacy. Among the 42 patients who underwent surgery, 16 patients (38.0%) achieved pCR. Thirty-three patients (78.6%) achieved pT < 2. With a median follow-up of 15.7 months, the 1-year event-free survival was 91.3%. Notwithstanding the poor pathological baseline characteristic of a high T3-T4a proportion (39.1%), a promising bladder preservation (including 22 patients transurethral resection of bladder tumor, 5 patients partial cystectomy, and 4 surveillances) rate was achieved (67.4%). The most common grade ≥ 3 treatment-related adverse events was neutropenia (n=15, 27.3%), which was related to chemotherapy. There were no grade 3 immune-related adverse events. Conclusion Neoadjuvant GP plus sintilimab is a promising regimen for MIBC patients, with relatively high pT < 2 rate and triggering the emerging roles for the multi-disciplinary team decision-making for bladder sparing surgery.

Objective:To analyze the effects of doctor-nurse-patient shared decision-making (SDM) and enhanced recovery after surgery (ERAS) nursing in patients undergoing radical gastrectomy for gastric cancer.Methods:A total of 186 patients who underwent radical gastrectomy for gastric cancer at the First Affiliated Hospital of Zhengzhou University from December 2022 to January 2024 were selected using convenience sampling and randomly divided into a control group and an observation group, with 93 patients in each group. The control group received routine ERAS nursing, while the observation group received SDM-based ERAS nursing intervention. Postoperative gastrointestinal function recovery, Self-Management Behavior Scale (SMBS), Shared Decision-Making Questionnaire (SDM-Q-9), Satisfaction with Medical Decision-Making Scale, and Decision Conflict Scale (DCS) scores were compared between the two groups.Results:The observation group had significantly shorter time for first flatus, first defecation, first ambulation, drainage tube removal, and hospitalization compared to the control group ( P<0.05). At 30 days postoperatively, SMBS scores in all dimensions were significantly higher in the observation group than in the control group ( P<0.05). SDM-Q-9 and decision-making satisfaction scores were higher, and DCS scores were lower in the observation group compared to the control group, with statistically significant differences ( P<0.05) . Conclusions:Doctor-nurse-patient SDM-based ERAS nursing promotes postoperative gastrointestinal function recovery in patients undergoing radical gastrectomy, enhances self-management ability, increases shared decision-making participation, and reduces decision-making conflict, demonstrating significant clinical value.

Objective To investigate the protective effect and mechanism of Polygonatum sibiricum polysaccharides(PSP)on diabetic cardiomyopathy(DCM).Methods Forty SPF-grade male Sprague-Dawley rats were divided randomly into Control,Model,PSP,and metformin groups.After 4 weeks of feeding a high-fat diet,streptozotocin was injected intraperitoneally to establish a rat model of diabetes mellitus.The drug was administered by gavage for 12 weeks,and body mass and blood glucose were recorded every 2 weeks.Cardiac function was detected by non-invasive echocardiography at week 16.Myocardial histopathological changes and the degree of myocardial fibrosis were assessed by hematoxylin and eosin and Masson staining.Serum interleukin(IL)-6,IL-1β,IL-18,tumor necrosis factor-α(TNF-α),triglycerides,total cholesterol,low-density lipoprotein,and high-density lipoprotein were detected by enzyme-linked immunosorbent assay.Expression levels of the fibrosis-related proteins transforming growth factor(TGF)-β1,Smad2,Collagen-Ⅰ,Collagen-Ⅲ,and the pyroptosis-related proteins NOD-like receptor thermal protein domain associated protein 3(NLRP3),apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),and Caspase-1 were detected in rat myocardial tissues by Western blot.Cellular experiments were performed by exposing H9c2 cells to high glucose(40 mmol/L)to mimic the in vitro DCM model,cell viability was detected by Cell Counting Kit-8 assay,and the apoptotic cell ratio was detected by flow cytometry.Results Rats in the treatment group had significantly lower blood glucose,lipid,and serum inflammatory factor levels compared with the model group(P＜0.05),significantly higher ejection fraction and fractional shortening values(P＜0.05),and improved cardiac function.Myocardial fibers were better aligned and collagen fiber accumulation was reduced,and myocardial tissue levels of NLRP3,ASC,Caspase-1,Collagen-Ⅰ,Collagen-Ⅲ,TGF-β1,and Smad2 were significantly reduced(P＜0.05).In the cellular assay,PSP increased the viability and decreased the proportion of apoptotic cells in high glucose-induced H9c2 cardiomyocytes.Conclusions PSP can improve glucose-lipid metabolism,protect cardiac function,and delay the occurrence of myocardial fibrosis in diabetic rats,and can also improve the viability of cardiomyocytes.Its mechanism of action may be related to the inhibition of cellular pyroptosis and delayed occurrence of ventricular remodeling.

Aromatherapy refers to the method of using the aromatic components of plants in appropriate forms to act on the entire body or a specific area to prevent and treat diseases. Essential oils used in aromatherapy are hydrophobic liquids containing volatile aromatic molecules， such as limonene， linalool， linalool acetate， geraniol， and citronellol. These chemicals have been extensively studied and shown to have a variety of functions， including reducing anxiety， relieving depression， promoting sleep， and providing pain relief. Terpenoids are a class of organic molecules with relatively low lipid solubility. After being inhaled， they can pass through the nasal mucosa for transfer or penetrate the skin and enter the bloodstream upon local application. Some of these substances also have the ability to cross the blood-brain barrier， thereby exerting effects on the central nervous system. Currently， the academic community generally agrees that products such as essential oils and aromatherapy from aromatic plants have certain health benefits. However， the process of extracting a single component from it and successfully developing it into a drug still faces many challenges. Its safety and efficacy still need to be further verified through more rigorous and systematic experiments. This article systematically elaborated on the efficacy of aromatic substances， including plant extracts and natural small molecule compounds， in antibacterial and antiviral fields and the regulation of nervous system activity. As a result， a deeper understanding of aromatherapy was achieved. At the same time， the potential of these aromatic substances for drug development was thoroughly explored， providing important references and insights for possible future drug research and application.

OBJECTIVE: To observe the effects of electroacupuncture (EA) at "Shenting" (GV24) and "Baihui" (GV20) on mitochondrial autophagy in hippocampal neurons and silent information regulator sirtuin 1 (Sirt1)/forkhead box O3 (FOXO3)/PTEN-inducible kinase 1 (PINK1)/Parkin pathway in rats with learning-memory impairment after cerebral ischemia reperfusion injury. METHODS: A total of 35 male SD rats were randomly divided into a sham operation group (9 rats) and a modeling group (26 rats). In the modeling group, middle cerebral artery occlusion method was used to establish the middle cerebral artery ischemia-reperfusion (MCAO/R) model, and 18 rats of successful modeling were randomly divided into a model group and an EA group, 9 rats in each one. EA was applied at "Shenting" (GV24) and "Baihui" (GV20) in the EA group, 30 min a time, once a day for 14 days. After modeling and on 7th and 14th days of intervention, neurologic deficit score was observed; the learning-memory ability was detected by Morris water maze test; the morphology of neurons in CA1 area of hippocampus was detected by Nissl staining; the mitochondrial morphology was observed by transmission electron microscopy; the protein expression of Beclin-1, microtubule-associated protein 1 light chain 3B (LC3B), P62, Sitrt1, FOXO3, PINK1 and Parkin was detected by Western blot. RESULTS: After modeling, the neurologic deficit scores in the model group and the EA group were higher than that in the sham operation group (P<0.001); on 7th and 14th days of intervention, the neurologic deficit scores in the model group were higher than those in the sham operation group (P<0.001), the neurologic deficit scores in the EA group were lower than those in the model group (P<0.05, P<0.01). After modeling, the escape latency in the model group and the EA group was prolonged compared with that in the sham operation group (P<0.001); on 9th-13th days of intervention, the escape latency in the model group was prolonged compared with that in the sham operation group (P<0.001), the escape latency in the EA group was shortened compared with that in the model group (P<0.05, P<0.01, P<0.001). The number of crossing plateau in the model group was less than that in the sham operation group (P<0.001); the number of crossing plateau in the EA group was more than that in the model group (P<0.05). In the model group, in CA1 area of hippocampus, the number of neurons was less, with sparse arrangement, nuclear fixation, deep cytoplasmic staining, and reduction of Nissl substance; the morphology of mitochondrion was swollen, membrane structure was fragmented, and autophagic lysosomes were formed. Compared with the model group, in the EA group, in CA1 area of hippocampus, the number of neurons was increased, the number of cells of abnormal morphology was decreased, and the number of Nissl substance was increased; the morphology of mitochondrion was more intact and the number of autophagic lysosomes was increased. Compared with the sham operation group, in the model group, the protein expression of Beclin-1, FOXO3, PINK1, Parkin and the LC3BⅡ/Ⅰ ratio in hippocampus were increased (P<0.01, P<0.001), while the protein expression of P62 was decreased (P<0.05). Compared with the model group, in the EA group, the protein expression of Beclin-1, Sirt1, FOXO3, PINK1, Parkin and the LC3BⅡ/Ⅰratio in hippocampus were increased (P<0.001, P<0.01), while the protein expression of P62 was decreased (P<0.001). CONCLUSION EA at "Shenting" (GV24) and "Baihui" (GV20) can relieve the symptoms of neurological deficits and improve the learning-memory ability in MCAO/R rats, its mechanism may relate to the modulation of Sirt1/FOXO3/PINK1/Parkin pathway and the enhancement of mitochondrial autophagy.
