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 explore the application effect of dexmedetomidine combined with ciprofol general anesthesia in laparoscopic radical resection of ovarian cancer.Methods:A total of 120 patients who underwent laparoscopic radical resection of ovarian cancer at the Hengshui Second People′s Hospital, Hebei Province from January 2021 to January 2023 were selected as the research objects. They were divided into the control group and the observation group by random number table method, with 60 cases in each group. Both groups underwent surgery under general anesthesia: the control group was given ciprofol, while the observation group was given dexmedetomidine combined with ciprofol. Postoperative recovery, changes in hemodynamics and vital signs, levels of stress indicators, and the occurrence of adverse reactions were compared between the two groups.Results:Compared with the control group, the observation group had fewer presses on the analgesic pump, shorter first flatus time and awakening time, lower Visual Analogue Scale (VAS) score at 1 hour after surgery, and higher Ramsay sedation score (all P<0.05). There were no statistically significant differences in heart rate (HR), mean arterial pressure (MAP), and bispectral index (BIS) between the two groups before induction (T 0) (all P>0.05); MAP at skin incision (T 1), 30 minutes after skin incision (T 2), and after extubation (T 3) in both groups were higher than those at T 0, while HR were lower than those at T 0 (all P<0.05); HR and MAP at T 1, T 2, and T 3 in the observation group were significantly lower than those in the control group (all P<0.05), but there was no statistically significant difference in BIS between the two groups at each time point (all P>0.05). There were no statistically significant differences in serum cortisol (COR) and adrenocorticotropic hormone (ACTH) levels between the two groups at T 0 (all P>0.05); serum COR and ACTH levels at T 3 and 1 hour after surgery (T 4) in both groups were higher than those at T 0 (all P<0.05), and the levels of serum COR and ACTH at T 3 and T 4 in the observation group were lower than those in the control group (all P<0.05). In the control group, there were 3 cases of hypotension, 7 cases of nausea and vomiting, and 1 case of respiratory depression; in the observation group, there were 2 cases of hypotension and 3 cases of nausea and vomiting. No serious adverse reactions occurred in either group, and the total incidence of adverse reactions in the observation group was lower than that in the control group (χ 2=3.354, P<0.05). Conclusions:Dexmedetomidine combined with ciprofol general anesthesia can promote postoperative recovery of patients undergoing laparoscopic radical resection of ovarian cancer, effectively stabilize hemodynamics, and reduce stress response and adverse reactions.

Objective:To investigate the short-term pulmonary function outcomes in children with congenital diaphragmatic hernia (CDH) following surgery and analyze the influencing factors of poor outcomes.Methods:This study retrospectively enrolled 81 children who had undergone surgery for CDH and were discharged after recovery at the Department of Neonatal Surgery, Children's Hospital of Capital Institute of Pediatrics from January 2020 to June 2023. All children had pulmonary function tests before discharge, 6 months to 2 year after discharge. Changes in the pulmonary function parameters at different time points were compared. Based on the results of the final pulmonary function test after discharge, these patients were categorized into a favorable outcome group (32 cases) with normal pulmonary function and an unfavorable outcome group (49 cases) with pulmonary dysfunction. Clinical data of the two groups were compared using two independent samples t-test, rank-sum test, Chi-square test, or Fisher's exact test. Logistic regression analysis was used to explore the factors influencing pulmonary function outcomes. Results:A total of 81 cured and discharged CDH children were included in this study, comprising 34 males (42.0%) and 47 females (58.0%). The first two pulmonary function tests were performed at a mean postnatal age of (30.1±14.1) d (14-75 d) and (8.3±1.3) months (4 months and 14 d to 12 months), respectively. Pre-discharge pulmonary function tests revealed that 13 cases (16.0%) had nearly normal pulmonary function, while 68 cases (84.0%) showed pulmonary function abnormalities with seven cases of restrictive ventilatory dysfunction, 56 cases of obstructive ventilatory dysfunction, and five cases of mixed ventilatory dysfunction. In the children with abnormal pulmonary function before discharge, their second pulmonary function tests showed that some parameters including tidal volume [(7.49±1.35) ml/kg vs. (8.02±2.21) ml/kg], the ratio of time to peak tidal expiratory flow and expiratory time [(23.21±4.95)% vs. (26.50±5.48)%], the ratio of volume to peak expiratory flow and expiratory volume [(26.41±5.79)% vs. (27.55±5.20)%], respiratory system compliance per kg body weight during single occlusion [(0.93±0.22) ml/(cmH 2O·kg) vs. (0.96±0.25) ml/(cmH 2O·kg), 1 cmH 2O=0.098 kPa], functional residual capacity [(52.18±17.83) ml vs. (126.39±26.73) ml], and respiratory system resistance in single occlusion condition [(0.06±0.02) cmH 2O/(ml·s) vs. (0.05±0.01) cmH 2O/(ml·s)] improved after discharge ( t values were－2.41,－6.14,－7.68,－2.26,－18.94, and 4.87, all P<0.05). Eight children with obstructive ventilatory dysfunction were followed up for two years after surgery, of which three had normal lung function and five still showed mild to moderate obstructive ventilatory dysfunction. Logistic regression analysis indicated that liver herniation, severe pulmonary hypertension (PH), low observed-to-expected lung-to-head ratio (o/e LHR), grade C/D diaphragmatic defect, and prolonged invasive ventilation were risk factors for poor pulmonary outcomes [ OR(95% CI) were 5.655(1.410-22.676), 5.610 (1.589-19.804),4.183 (1.234-14.180) and 1.195(1.074- 1.329), all P<0.05]. Conclusions:Although lung function parameters of CDH patients show certain improvement after surgery, many children still have mild to moderate obstructive ventilatory dysfunction, requiring long-term follow-up. Prenatal and postnatal indicators such as liver herniation, severe PH, and low o/e LHR can predict the pulmonary outcomes of children with CDH.

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.
