Objective:To investigate the effects of dexmedetomidine (Dex) combined with propofol or cyclopropofol on postoperative stress in laparoscopic ovarian cancer surgery.Methods:A total of 120 ovarian cancer patients who underwent laparoscopic radical resection of ovarian cancer in the Second People′s Hospital of Hengshui from January 2022 to December 2023 were selected and divided into observation group and control group by random number table method, with 60 cases in each group. The control group was given Dex combined with propofol for compound anesthesia, and the observation group was given Dex combined with cyclopropofol for compound anesthesia. The perioperative indicators and intraoperative opioid dosage were compared between the two groups. The heart rate (HR) and mean arterial pressure (MAP) were compared at 3 min after entering the operating room (T 1), intubation (T 2), skin incision (T 3), extubation (T 4) and leaving the operating room (T 5). The Ramsay Sedation Scale (RSS) scores at T 1, T 2, T 3, T 4 and Prince-Henry scores at 2, 6, 12, 24 h after operation were compared. The serum levels of prostin E 2 (PGE 2) and cortisol (Cor) 1 day before operation and 12, 24, 48 h after operation, as well as the incidence of adverse events during treatment were compared between the two groups. Results:The anesthesia recovery time in the observation group was significantly shorter than that in the control group, and the intraoperative dosages of sufentanil and remifentanil were significantly less than those in the control group (all P<0.05). Compared with T 1, there were no significant differences in HR and MAP at T 2, T 3, T 4 in the observation group (all P>0.05); the HR and MAP at T 2, T 3, T 4 in the control group were significantly different from those at T 1 (all P<0.05), and the HR and MAP at T 2, T 3, T 4, T 5 in the observation group were lower than those in the control group (all P<0.05). The RSS scores at T 2, T 3 and T 4 in the observation group were significantly higher than those in the control group (all P<0.05). The Prince-Henry scores at 2, 6, 12, 24 h after operation in the observation group were significantly lower than those in the control group (all P<0.05). The serum PGE 2 and Cor levels at 12, 24 and 48 h after operation in the observation group were significantly lower than those in the control group (all P<0.05). The total incidence of postoperative adverse events in the observation group was 18.33%(11/60), lower than 23.33%(14/60) in the control group ( P<0.05). Conclusions:Compared with Dex combined with propofol, Dex combined with cyclopropofol for compound anesthesia can reduce postoperative stress response in laparoscopic ovarian cancer surgery, improve intraoperative sedation and postoperative analgesia, stabilize hemodynamics, and has good safety.

OBJECTIVE: Therapeutic angiogenesis has become a promising approach for treating ischemic heart disease (IHD). The present study aims to investigate the effects of Qishen Granule (QSG) on angiogenesis in myocardial ischemia (MI) and the potential mechanism. METHODS: In vivo study was conducted on rat model of myocardial infarction. QSG was performed daily at a dose of 2.352 g/kg for four weeks. Cardiac function was assessed by echocardiogram and pro-angiogenic effects were evaluated by Laser Doppler and CD31 expression. Oxygen-glucose deprivation (OGD) was applied in cultured human umbilical vein endothelial cells (HUVECs). Cell viability, wound healing and tube formation assay were used to test functions of HUVECs. ELISA and Western blots were used to assess protein expressions of bone morphogenetic protein 2-delta-like 4-notch homolog 1 (BMP2-Dll4-Notch1) signaling pathway. RESULTS: The results showed that QSG improved heart function, cardiac blood flow and microvessel density in myocardial ischemic rats. In vitro, QSG protected HUVECs by promoting the cell viability and tube formation. QSG upregulated bone morphogenetic protein-2 (BMP2) and downregulated delta-like 4 (Dll4) and notch homolog 1 (Notch1) expressions both in rats and HUVECs. CONCLUSION QSG protected against MI by promoting angiogenesis through BMP2-Dll4-Notch1 pathway. BMP2 might be a promising therapeutic target for IHD.

OBJECTIVE To investigate the effectiveness of resident clinical pharmacist-led medication therapy management （MTM） model in geriatric cardiology departments， and provide reference for optimizing resident pharmaceutical services. METHODS A retrospective cohort study was conducted， incorporating data from inpatients admitted to the Department of Cardiovascular Medicine in the Geriatric Medical Center of our hospital during March to August 2023 （conventional group， n＝ 903） and the same period in 2024 （MTM group， n＝963）. The conventional group received only standard pharmaceutical services （including prospective prescription review and retrospective order evaluation）， while the MTM group received additional resident clinical pharmacist-led interventions-such as medication reconciliation， personalized therapeutic drug monitoring （TDM）， standardized intravenous infusion management， and a four-stage closed-loop monitoring process-based on conventional care. The effectiveness of the MTM model was evaluated by comparing the primary outcome measures （e.g.， intravenous infusion rate， TDM target attainment rate） and secondary outcome measures [e.g.， incidence of drug-drug interactions （DDIs）， incidence of grade 3 or higher acute kidney injury， average length of hospital stay， cholesterol， and medication cost per capita] between the two groups. RESULTS Compared with the conventional group， in terms of primary outcome indexes： both the overall intravenous infusion rate and the use rate of acid-suppressive injection were significantly lowered in the MTM group （P＜0.05）； serum concentration target attainment rates for digoxin and vancomycin were increased significantly （P＜0.05）. For secondary outcome indexes， the MTM group exhibited significant decreases in the work incidence of grade 3 or higher acute kidney injury， the incidence of DDIs， the rate of patients leaving the hospital against medical advice， alanine amino-transferase， aspartate transferase and the per capita total medication cost （P＜0.05）. Additionally， there was a notable increase in the creatinine， estimated glomerular filtration rate and a significant shortening of the per capita length of hospital stay （P＜0.05）. CONCLUSIONS The resident clinical pharmacist-led MTM model can significantly optimize medication therapy processes， enhance medication safety and cost-effectiveness， thus playing a positive role in promoting rational drug use and improving patient outcomes.

Objective:To explore the relevant factors affecting the accuracy of scanning glucose monitoring (FGM) technology in critically ill patients.Methods:A total of 53 patients who were admitted to the Intensive Care Unit (ICU) of the Second Affiliated Hospital of Soochow University and used FGM glucose monitoring from September 2022 to December 2023 were selected by means of a convenience sampling method. The paired data of arterial blood glucose and FGM glucose were analysed. The accuracy of FGM blood glucose measurement in critically ill patients was evaluated using Bland-Altman analysis. The blood glucose data were divided into two groups: the FGM monitoring accuracy group and the FGM monitoring non-accuracy group.. The t-test and χ2 test were used for the comparison of one-way analysis of arterial versus FGM accuracy among critically ill patients with different demographic characteristics. Logistic regression analysis was used to analyze the factors influencing the accuracy of FGM. Results:The results of Bland-Altman analysis of the 53 patients indicated that the mean bias value of FGM blood glucose was elevated at 1.215 mmol/L in comparison with arterial-blood gas analysis blood glucose values. An incidence of exceeding the upper and lower limits of the range was observed, amounting to 6.349%. The discrepancy between the studies was found to be statistically significant (95% CI:1.0394~1.3908, P<0.001). The effects of the changes in height ( OR=0.877, 95% CI:0.780~0.987, P=0.029), changes in leukocyte counts( OR=0.917, 95% CI:0.868~0.969, P=0.002), changes in C-reactive protein( OR=1.009, 95% CI:1.002~1.017, P=0.016), changes in albumin counts( OR=0.986, 95% CI:0.974~0.999, P=0.031), and whether or not sepsis ( OR=3.937, 95% CI:1.192~13.008, P=0.025) on the accuracy of FGM had a statistically significant. Conclusion:The mean bias value of the accuracy of FGM was relatively higher compared with that of arterial blood gas analysis blood glucose values, and the influencing factors involved height, white blood cells, C-reactive protein, albumin, and whether or not sepsis was present. With the development of science and technology, applying the FGM system to critically ill patients has an absolute advantage in determining the overall glycemic trend, and the application value of FGM technology deserves further study.

Beta-amylases (BAMs), key enzymes in starch hydrolysis, play an important role in plant growth, development, and resistance to abiotic stress. To mine the saline-alkali tolerance-related BAM genes in alfalfa (Medicago sativa L.), we identified MsBAM genes in the whole genome. The physicochemical properties, phylogeny, gene structures, conserved motifs, secondary structures, promoter cis-acting elements, chromosome localization, and gene replication relationships of BAM gene family members were analyzed. RNA-seq and quantitative real-time PCR (qRT-PCR) were employed to analyze the expression patterns of BAM family members under saline-alkali stress. The results showed that 54 BAM genes were identified in the genome, which were classified into 8 subgroups according to the phylogenetic tree. The members of the same subgroup had similar gene structures except that those of subgroups 1 and 7 had large differences. Conserved motif analysis showed that all MsBAM proteins had a typical glycohydrolysis domain. The chromosome localization analysis showed that MsBAM gene family members were unevenly distributed on 27 chromosomes. The duplication of gene segments led to the increase in BAM gene number in alfalfa. The promoters of BAM genes contained a large number of elements in response to plant hormones and stress. Transcriptome data and qRT-PCR results showed that the expression levels of most MsBAM genes were up-regulated in response to saline-alkali stress. Under the saline-alkali stress, the expression levels of 28 genes, including MsBAM6, were up-regulated on days 1 and 7, and those of 5 genes, including MsBAM9, were up-regulated by over 2 folds. In addition, under salt-alkali stress, BAM activity and soluble sugar content were significantly increased. These results indicate that BAM genes play a key role in alfalfa in response to saline-alkali stress, laying a foundation for further research in this field.

Ischemic stroke(IS)is a disease caused by insufficient blood and oxygen supply to cerebral vessels,with the main clinical manifestations of hemiplegia,sensory disturbance,aphasia,and ataxia.Studies have shown that hypoxia-inducible factor 1α(HIF-1α),as the core regulatory element of oxygen homeostasis,can be rapidly activated under hypoxia/ischemia conditions,thereby playing an important role in the pathophysiology of IS.In recent years,more and more articles have shown that the active components of tradi-tional Chinese medicine,Chinese patent drugs,and compound traditional Chinese medicine prescriptions can effectively regulate the HIF-1α-related signaling pathway in the treatment of IS,but there is no systematic summary on regulation of the HIF-1α signaling pathway in the treatment of IS.Therefore,this article mainly summarizes the structure and physiological activity of HIF-1α and its mechanisms of action in IS and reviews related studies on Chinese medicine monomers and compound prescriptions in the treatment of IS in the past five years in China and globally.It is pointed out that the Chinese medicine monomers and compound prescriptions can repair brain tissue,alleviate brain tissue damage,and exert a therapeutic effect on IS by regulating the HIF-1α pathway to promote an-giogenesis,inhibit neuroinflammation and oxidative stress,promote energy metabolism,and repair blood-brain barrier damage.

Objective:To construct a predictive model for hemorrhagic transformation (HT) after intravenous thrombolysis in elderly patients with acute cerebral infarction (ACI) using the Lasso-Logistic regression model, and to analyze the clinical utility of this predictive model.Methods:A total of 310 elderly ACI patients who received intravenous thrombolysis with alteplase (rt-PA) at the Beijing Rehabilitation Hospital Affiliated to Capital Medical University from May 2022 to May 2024 were selected. The occurrence of HT within 36 hours after intravenous thrombolysis was recorded, and the patients were divided into the HT group and non-HT group based on the presence or absence of HT. Clinical data were compared between the two groups. Lasso-Logistic regression analysis was used to screen the influencing factors of HT after intravenous thrombolysis in elderly ACI patients. A nomogram predictive model for HT after intravenous thrombolysis in elderly ACI patients was constructed based on these influencing factors, and the clinical value of the nomogram predictive model was analyzed.Results:The incidence of HT within 36 hours after rt-PA intravenous thrombolysis in elderly ACI patients was 29.35%(91/310). The proportions of patients with hypertension, diabetes, anticoagulant use, and atrial fibrillation in the HT group were higher than those in the non-HT group. The onset-to-thrombolysis time (ONT), admission National Institute of Health Stroke Scale (NIHSS) score, pre-thrombolysis peripheral blood platelet count, neutrophil-to-lymphocyte ratio (NLR), and serum levels of high-sensitivity C-reactive protein (hs-CRP), vascular endothelial cadherin (VE-cad), occludin, soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1), and endothelial cell-specific molecule 1 (ESM-1) in the HT group were higher than those in the non-HT group (all P<0.05). Lasso-Logistic regression analysis showed that atrial fibrillation, ONT, admission NIHSS score, pre-thrombolysis peripheral blood NLR, and serum levels of hs-CRP, VE-cad, occludin, sLOX-1, and ESM-1 were independent risk factors for HT after intravenous thrombolysis in elderly ACI patients (all P<0.05). The area under the curve (AUC) of the constructed nomogram predictive model for predicting HT after intravenous thrombolysis in elderly ACI patients was 0.914(95% CI: 0.879-0.949), indicating high predictive efficiency. When the threshold probability range was 0.05-0.83, the nomogram predictive model showed good net benefit in predicting HT after intravenous thrombolysis in elderly ACI patients and had high clinical utility in predicting the risk of HT. Conclusions:Atrial fibrillation, ONT, admission NIHSS score, pre-thrombolysis peripheral blood NLR, and serum levels of hs-CRP, VE-cad, occludin, sLOX-1, and ESM-1 are independent risk factors for HT after intravenous thrombolysis in elderly ACI patients. The nomogram predictive model constructed based on these factors has high predictive efficiency and clinical utility in predicting the risk of HT.
