OBJECTIVE To explore a new model of intelligent medication education for pharmaceutical outpatient clinics by constructing dynamic HTML web pages through the DeepSeek-V3-0324 large-scale model. METHODS Clinical pharmacists integrated key clinical information such as patients’ basic information， medication history and medication precautions in real time， and generated a standardized medication education list through the DeepSeek-V3-0324 large-scale model and manual review. RESULTS The DeepSeek-V3-0324 large-scale model was applied in the pharmaceutical outpatient clinics to generate a personalized medication education list， which could effectively solve the disunity of pharmacy guidance caused by the lack of standardization of medication education and the difference of individualized experience of pharmacists in the traditional pharmaceutical outpatient clinics in the face of complex cases， and medication errors caused by forgetting or misremembering information among certain special patient populations after receiving medication education. CONCLUSIONS The transformation and application of artificial intelligence technology in pharmaceutical outpatient clinics is an innovation of pharmaceutical outpatient service means， which can provide patients with immediate and personalized medication education and improve the quality of pharmaceutical care. However， it is also necessary to face the lag of database update and the lack of risk management， as well as the lack of diversification of medication education lists.

Objectives:To observe the mitochondrial morphology of normal and triple-negative breast cancer cells, extract mitochondria from normal cells, and investigate the effects of mitochondrial transplantation on proliferation, apoptosis, and stemness of triple-negative breast cancer cells.Methods:The morphology of mitochondria was observed by transmission electron microscope. Mitochondria were extracted by mitochondrial extraction kit, mitochondrial protein was identified by western blot, and mitochondrial activity was detected by mitochondrial membrane potential detection kit. MitoTracker Green or MitoTracker Deep Red fluorescent probes were used to label the mitochondria of living cells, and the degree of mitochondria entering LTT cells was observed by confocal laser microscopy at 12, 24, and 96 hours. The effects of mitochondrial transplantation on proliferation, apoptosis, and stemness of breast cancer cells were examined by CCK8, colony formation assay, flow cytometry, and sphere formation assay after 24 hours of mitochondrial transplantation.Results:The mitochondria of normal cells were rod-shaped or elongated, while the mitochondria of triple-negative breast cancer cells were swollen and vacuolated. Western blot results showed that cytochrome c oxidase subunit I (MT-CO1) protein encoded by mitochondria was present in the isolated mitochondria. The content of heat shock protein 60 (HSP60) was higher in mitochondria than that in cytoplasm. The result of the multi-mode microplate reader showed that the content of mitochondrial J-aggregates/monomer was 1.67±0.06, which was significantly higher than 0.35±0.04 of the control group ( P＜0.001). Exogenous mitochondria were observed in LTT cells at 12, 24, and 96 hours after mitochondrial transplantation. The results of the CCK8 experiment showed that OD450 of LTT cells was 0.27±0.13 after 48 hours transplantation, which was lower than 0.62±0.36 of the control group ( P=0.023). The OD450 of MDA-MB-468 cells was 0.30±0.03, which was lower than 0.65±0.10 of the control group ( P=0.004). After 120 hours of mitochondrial transplantation, OD450 in both groups was still significantly lower than that in the control group (P＜0.01). The number of clones formed by mitochondrial transplantation of LTT cells was 21.33±7.31, which was lower than 35.22±13.59 of the control group ( P=0.016). Flow cytometry showed that the early apoptosis rate of LTT cells was (30.07±2.15)% after 24 hours of mitochondrial transplantation, which was higher than 2.07±1.58 of the control group ( P＜0.001). The proportion of early apoptosis in MDA-MB-468 cells was 24.47%±5.22%, which was higher than (7.83±2.06)% in the control group ( P=0.007). In addition, the number of mitochondria transplanted LTT cells into the cell sphere was 46.25±5.40, which was significantly lower than 62.58±6.43 of the control group ( P＜0.001). Conclusion:Normal mitochondria can enter triple-negative breast cancer cells by co-culture, inhibit the proliferation and stemness of triple-negative breast cancer cells, and promote the apoptosis of triple-negative breast cancer cells.

Objective:To train a deep convolutional neural networks (CNN) using a labeled data set to classify the metaphase chromosomes and test its accuracy for chromosomal identification.Methods:Three thousand and three hundred individuals undergoing surveillance for chromosomal disorders at the Laboratory for Comprehensive Prevention and Treatment of Birth Defects, Ningbo Maternal and Child Health Care Hospital from January 2013 to July 2019 were enrolled. A total of 3 300×46 chromosome images were included, of which 70% were used as the training set and 30% were used as the test set for the deep CNN. The accuracy of chromosome counting and "cutting + recognition + arrangement + automatic analysis" of the model were respectively evaluated. Another 80 images were collected to record the time and accuracy of chromosome classification by geneticists and the model, respectively, so as to assess the practical value of the model.Results:The CNN model was used to count the chromosomes with an accuracy of 61.81%, and the "cutting + recognition + arrangement + automatic analysis" accuracy of the model was 96.16%. Compared with manual operation, the classification time of the CNN model has been greatly reduced, and its karyotyping accuracy was only 3.58% lower than that of geneticists.Conclusion:The CNN model has a high performance for chromosome classification and can significantly reduce the work load involved with the segmentation and classification and improve the efficiency of chromosomal karyotyping, thereby has a broad application prospect.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objective To observe and compare the effect of remimazolam combined with nalbuphine and midazolam combined with nalbuphine on postoperative recovery in elderly patients undergoing fibrobronchoscopy.Methods A total of 112 elderly patients undergoing fibrobronchoscopy,56 males and 56 females,aged ≥ 65 years,BMI 18.5-28.0 kg/m2,ASA physical status I or Ⅱ,were ran-domly divided into two groups:midazolam group and remimazolam group,56 patients in each group.The midazolam group received midazolam 0.03 mg/kg combined with nalbuphine 0.1 mg/kg for anesthesia.The remimazolam group received remimazolam 0.1 mg/kg combined with nalbuphine 0.1 mg/kg for anesthesia.HR,MAP,SpO2,and RR were recorded after entering room,before anesthesia induction,5 minutes after anesthesia induction,and at the end of the operation.The onset time of anesthesia,the time of awakening,the time of operation,the time of discharge,the number of successful cases of sedation,the number of suc-cessful cases of endoscopy,and the occurrence of adverse events were recorded.The satisfaction of the pa-tient,anesthesiologist,and endoscopist were also recorded.Results Compared with the midazolam group,HR and MAP were significantly increased 5 minutes after induction and the end of operation in the remima-zolam group(P＜0.05),the onset time of anesthesia and the time of awakening were significantly short-ened(P＜0.05),the incidence of hypotension,respiratory depression and nausea and vomiting were sig-nificantly reduced(P＜0.05),and the rae of very satisfaction of the operating physician was significantly increased(P＜0.05).There were no significant differences in the time of separation,the success rate of sedation and the success rate of endoscopy between the two groups.Conclusion Compared with midazolam,remimazolam combined with nalbuphine can be safely used for flexible bronchoscopy in elderly patients,reduce recovery time and adverse reactions,which is conducive to rapid postoperative recovery.

Objective:To investigate the clinical efficacy of non-drug interventions in hospice and palliative care(HPC)for improving cancer-related fatigue(CRF)in elderly individuals and its impact on quality of life.Methods:This study presents findings from a single-center randomized controlled trial conducted at Zhejiang Hospital, focusing on 40 elderly patients experiencing cancer-related fatigue(CRF)between February 2022 and February 2023.The participants were randomly assigned into a control group and an intervention group, each consisting of 20 individuals, using the random number table method.Both groups received routine comprehensive treatment, with the intervention group additionally receiving hospice and palliative care(HPC)non-drug intervention.Following 6 weeks of continuous treatment, the study compared the clinical efficacy, changes in CRF, and quality of life before and after treatment between the two groups.Results:Comparing the baseline data of the two groups of patients, the difference was not statistically significant(all P>0.05).After 6 weeks of treatment, patients in the intervention group reported lower levels of current fatigue, general fatigue, worst fatigue in the past 24 hours, and impact of fatigue on various aspects of their lives compared to the control group(all P<0.01).The clinical remission rate of cancer-related fatigue(CRF)in the intervention group was 60%, significantly higher than the 5% in the control group( P<0.01).Additionally, the intervention group showed improvement in overall quality of life and emotional function with decreased symptom areas scores(fatigue, nausea and vomiting, shortness of breath, sleep disorders, and loss of appetite)( P<0.01 for quality of life and emotional function, P<0.05 for symptom areas). Conclusions:Non-pharmacological interventions within the context of hospice and palliative care have been shown to alleviate cancer-related fatigue in elderly cancer patients, ultimately improving their quality of life.These interventions have demonstrated positive effects on various aspects such as overall quality of life, functional status, fatigue, nausea and vomiting, shortness of breath, sleep disorders, and decreased appetite.Furthermore, these interventions are considered safe and effective in the treatment of elderly cancer patients experiencing fatigue.

Objective To analyze the occurrence status and influencing factors of esophageal stenosis after surgery for early esophageal cancer. Methods A total of 285 patients with early esophageal cancer with endoscopic submucosal dissection (ESD) in the hospital from January 2019 to January 2021 were selected as research objects, and they were divided into control group with 237 cases (without esophageal stenosis) and study group with 48 cases (with esophageal stenosis) according to the occurrence of esophageal stenosis after surgery. The operation time, intraoperative blood loss and quality of life were compared between the two groups. The influencing factors of esophageal stenosis were analyzed. Results Compared with the control group, the study group had longer operation time, more intraoperative blood loss, and lower scores in psychological, environmental, physiological and social dimensions, and the between-group differences were statistically significant (P<0.05). Univariate analysis showed that esophageal stenosis after ESD had no correlations with gender, clinical stage, pathological type, history of drinking, the American Society of Anesthesiologists (ASA) classification, and anesthesia method (P>0.05). Patients aged ≥60 years old, damage of the muscularis propria, circumferential extent of lesion >3/4, malnutrition, tissue infiltration depth of M3+SM1, and longitudinal length of lesion >40 mm had a higher incidence of esophageal stenosis (P<0.05). Multivariate Logistics regression analysis showed that malnutrition, age ≥60 years, circumferential extent of lesion >3/4, damage of the muscularis propria, tissue infiltration depth of M3+SM1, and longitudinal length of lesion >40 mm were the main influencing factors for esophageal stenosis after ESD (P<0.05). Conclusion The occurrence of esophageal stenosis after ESD in patients with early esophageal cancer is related to factors such as damage of the muscularis propria, malnutrition, age ≥60 years, tissue infiltration depth of M3+SM1, circumferential extent of lesion >3/4, and longitudinal length of lesion >40 mm. Based on these factors, early prevention and control can be carried out to reduce the incidence of esophageal stenosis after surgery.

Objective:To investigate the mechanism of dexmetomidine (DEX) in improving lung injury in septic mice.Methods:Male C57BL/6 mice were randomly assigned to the blank group (NC), sham operation group (sham), cecal ligation and puncture group (CLP), and Dex treatment group (CLP+DEX), 36 mice per group. Mice in the CLP group were intraperitoneally injected with 1 mL sterile saline 15 min before CLP, and mice in the CLP + DEX group were intraperitoneally injected with 50 μg/kg DEX 15 min before CLP. The survival rate was recorded within 24 h after CLP. The mice were sacrificed at 0, 3, 6, 12, and 24 h after CLP, and lung tissues were collected. The expression levels of cytokines (IL-6, IL-1β, TNF-α) and lncRNA-HOTAIR in the lung of mice were detected by qPCR. RAW264.7 cell were cultured in vitro, LPS (100 ng/mL) and DEX (1 μ mol/L) were used to establish a cell model for studying the mechanism of Dex, and the expression of cytokines (IL-6, IL-1β, TNF-α) and lncRNA-HOTAIR in RAW264.7 cell model were detected by qPCR. In addition, the effect of lncRNA-HOTAIR on sepsis was explored in vivo and in vitro by knockdown or overexpression of HOTAIR.Results:The survival rate of the CLP+DEX group was higher than that of the CLP group within 24 h after surgery, and the levels of IL-6, IL-1β, and TNF-α in the lungs were significantly lower than those in the CLP group at 6, 12, and 24 h after surgery ( P<0.05). In addition, the level of lncRNA HOTAIR showed that the expression level of lncRNA HOTAIR in the lungs of mice were decreased after Dex treatment, and were decreased 1.1 times ( P<0.05), 4.0 times ( P<0.01) and 3.8 times ( P<0.01) at 6, 12, and 24 h, respectively. Compared with the NC group, knockdown of HOTAIR significantly decreased the levels of IL-1β, IL-6, and TNF-α in septic mice ( P<0.05), and overexpression of HOTAIR significantly increased the levels of IL-1β, IL-6, and TNF-α in septic mice ( P<0.01). Conclusions:DEX can reduce the production of inflammatory factors in the lungs of septic mice and improve the survival rate of septic mice. The mechanism may be related to the inhibition of HOTAIR expression.
