Objective:To explore the longitudinal trajectory of sleep disorders and their influencing factors in newly diagnosed breast cancer patients, and provide theoretical basis for formulating intervention measures to improve sleep quality of breast cancer patients.Methods:A longitudinal study was conducted using convenience sampling to select newly diagnosed breast cancer patients from Shandong Provincial Third Hospital and Shandong First Medical University Affiliated Provincial Hospital from April 2023 to June 2024. General information questionnaires, the Pittsburgh Sleep Quality Index (PSQI), the Concerns About Recurrence Scale (CARS), and the Distress Disclosure Index (DDI) were used for the survey. The Kruskal-Wallis H test and generalized estimating equation models were used to examine sleep disorders and their influencing factors. Results:A total of 473 valid questionnaires were collected. Among the 473 newly diagnosed breast cancer patients, 435 were female and 38 were male, aged (49.5 ± 11.0) years old. The CARS score at admission was (3.00 ± 1.12) points, with concerns about death (0.71 ± 0.67) points and concerns about female characteristics (0.81 ± 0.72) points. The DDI score at admission was (27.00 ± 10.03) points. The PSQI scores at admission, discharge, and one month after discharge were (15.34 ± 3.05), (12.12 ± 3.01), and (10.13 ± 1.78) points, respectively, the difference was statistically significant ( H =33.19, P<0.05). The PSQI scores at these three time points were positively correlated with the CARS score and concerns about death and female characteristics ( r values were 0.42-0.79, all P<0.05), and negatively correlated with the DDI score ( r =-0.41, -0.37, -0.31, all P<0.05). The generalized estimating equation model showed that female gender ( β=1.35, 95% CI 0.27-2.30), education level of junior high school or below ( β=1.89, 95% CI 0.24-3.19), severe pain ( β=1.72, 95% CI 0.32-3.12), moderate pain ( β=2.51, 95% CI 0.37-4.66), invasive special cancer ( β=2.57, 95% CI 1.67-4.07), invasive non-special cancer ( β=2.11, 95% CI 1.98-3.12), partial understanding of the condition ( β=1.91, 95% CI 1.23-3.01), concerns about death ( β=1.61, 95% CI 0.17-2.78), and concerns about femininity ( β=1.34, 95% CI 0.37-2.15) positively predicted the sleep quality index in newly diagnosed breast cancer patients (all P<0.05). Non-invasive cancer ( β=-3.82, 95% CI -6.79--3.36), lack of understanding of the condition ( β=-3.96, 95% CI -7.09--4.62), and DDI score ( β=-1.45, 95% CI -2.14--0.15) negatively predicted the sleep quality index (all P<0.05). Conclusions:The overall sleep quality of newly diagnosed breast cancer patients is low, with the lowest at admission and gradual improvement at discharge and one month after discharge. Medical staff should pay attention to high-risk patients who are female, have lower education levels, higher pain scores, poorer pathological types, and partial understanding of their condition.

Objective To analyze the influence of Dapagliflozin on ventricular remodeling,soluble suppression of tumorigenicity-2(sST2)and brain natriuretic peptide(BNP)in patients with elderly ST-segment elevation myocardial infarction(STEMI)complicated with type 2 diabetes mellitus(T2DM)after percutaneous coronary intervention(PCI).Methods From April 2021 to March 2023,118 elderly patients with STEMI complicated with T2DM treated by PCI were selected from People's Hospital of Hengshui.They were divided into conventional hypoglycemic therapy control(Con,n=59)group and conventional hypoglycemic therapy combined with Dapagliflozin(Dap,n=59)group according to the treatment strategy.All the participants were treated for 24 weeks.The general data,biochemical indexes,BNP,N-terminal pro-B-type natriuretic peptide(NT-proBNP),soluble growth stimulating expression factor 2(sST2)and lipoprotein-associated phospholipase A2(LP-PLA2),left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),and left ventricular mass index(LVMI)were compared between the two groups.Results After 24 weeks of treatment,the BNP,NT-proBNP,fasting plasma glucose(FPG),2 h postprandial blood glucose(2 hPG),glycosylated hemoglobin(HbA1c),LVEDD,LVESD,LVMI,serum sST2 and LP-PLA2 were lower in Dap group than in Con group(P<0.05),while the LVEF was higher in Dap group than in Con group(P<0.05).The total incidence rate of major adverse cardiovascular events was significantly lower in Dap group than in Con group(P<0.05).The incidence rates of adverse drug reactions were 6.78%and 5.08%in the two groups respectively(P>0.05).Conclusions Dapagliflozin can improve the cardiac function and glucose metabolism status in elderly patients with STEMI and T2DM after PCI,and alleviate the ventricular remodeling,with good safety.

Objective:To investigate the clinical efficacy of open anterior myofascial repair surgery on abdominal wall incision hernia.Methods:The retrospective cohort study was conducted. The clinical data of 188 patients who underwent open anterior myofascial repair surgery on abdo-minal wall incision hernia at three medical centers, including Xiangya Hospital of Central South University et al, from December 2016 to December 2024 were collected. There were 85 males and 103 females, aged (62±12)years. Of the 188 patients, 55 cases had large incisional hernia and 133 cases had non-large incisional hernia. Observation indicators: (1) intraoperative conditions; (2) postopera-tive conditions; (3) follow-up. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test or Fisher exact test. Comparison of ordinal data between groups was conducted using the nonparametic test. Results:(1) Intra-operative conditions. The operation time of the 55 patients with large incisional hernia was (145±40)minutes, and the volume of intraoperative blood loss was 40.0(22.5,55.0)mL, cases with fascial defect located in the central anterior abdominal wall, the superolateral quadrant, the inferolateral quadrant were 26, 7, 22, the fascial defect area was 140(99,169)cm2, cases used with self-fixating mesh and flat mesh were 29, 26. The above indicators of the 133 patients with non-large incisional hernia were (124±34)minutes, 35.0(30.0,45.0)mL, 47, 26, 60, 25(12,40)cm2, 67, 66, respectively. There were significant differences in operation time and fascial defect area between patients with large incisional hernia and non-large incisional hernia ( t=-3.651, Z=-10.339, P<0.05), and there was no significant difference in the volume of intraoperative blood loss, defect quadrant distribution, and mesh type ( Z=-0.501, χ2=2.692, 0.086, P>0.05). (2) Postoperative conditions. Of the 55 patients with large incisional hernia, 7 cases developed postoperative seroma, including 5 cases combined with concomitant surgical-site infection, and 4 additional cases developed with surgical-site infection. Of the 133 patients with non-large incisional hernia, 15 cases developed postoperative seroma, including 3 cases combined with concomitant surgical-site infection. There was a significant difference in surgical-site infection between patients with large incisional hernia and non-large incisional hernia ( χ2=10.707, P<0.05), and there was no significant difference in postoperative seroma ( χ2=0.079, P>0.05). The duration of postoperative hospital stay was 7(6, 9)days for the 55 patients with large incisional hernia and 5(4, 6)days for the 133 patients with non-large incisional hernia, showing a significant difference between them ( Z=-6.292, P<0.05). (3) Follow-up. All 188 patients were followed up for 43(range, 29-67)months. During the follow-up, 9 patients experienced hernia recurrence, including 7 patients with large incisional hernia and 2 patients with non-large incisional hernia. For the 7 patients of large incisional hernia with hernia recurrence, 4 cases underwent reoperation and 3 cases received conservative treatment. All 2 patients of non-large incisional hernia with hernia recurrence received conservative treatment. There was no significant difference in hernia recurrence between patients with large incisional hernia and non-large incisional hernia ( χ2=8.432, P<0.05). Results of chronic pain score at postoperative 3 month showed that among 55 patients with large incisional hernia, 40 cases had mild pain, 7 cases had moderate pain, and 8 cases had severe pain. Among 133 patients with non-large incisional hernia, the above indicators were 102, 28, and 3, respectively. There was no significant difference in chronic pain score at postoperative 3 month between patients with large incisional hernia and non-large incisional hernia ( Z=-0.968, P>0.05). Conclusions:Open anterior myofascial repair surgery can be used for the treatment of abdominal wall incision hernia. Compared with non-large incisional hernia, patients with large incisional hernia have longer operation time, are more prone to surgical-site infection, have longer postoperative hospital stay, and are more likely to experience hernia recurrence.

Objective To investigate the effects of Dapagliflozin combined with insulin treatment on blood glucose index and pancreatic β-cell function in overweight/obese type 2 diabetes mellitus(T2DM) patients with different disease durations. Methods A total of 288 patients with impaired pancreatic function who were treated from June 2019 to June 2020 were selected. They were divided into three groups,short duration group (≤10 years group,n=95),medium duration group (10～20 years group,n=96) and long duration group (≥20 years group,n=97). Three groups of patients were treated with Dapagliflozin in addition to the regular insulin therapy for 6 months. Clinical efficacy,blood glucose indices,pancreatic β-cell function and complications during the treatment period were compared among the three groups. Results After treatment,there was a significant decrease in the values of three groups including WC,FPG,2 hPG,HbA1c,TC,TG,LDL-C,BMI,FIns and HOMA-IR(P<0.05). Meanwhile,HDL-C,C-P,HOMA-β and HOMA-IS values showed a significant increase(P<0.05). After treatment,WC,FPG,2 hPG,HbA1c,TC,TG,LDL-C,FIns and HOMA-IR increased in turn(P<0.05),while HDL-C,C-P,HOMA-β and HOMA-IS decreased in turn in ≤10 years group,10～20 years group,≥20 years group(P<0.05). The BMI of 10～20 years group was lower than that of ≤10 years group and ≥20 years group (P<0.05),while the BMI of ≥20 years group was higher than that of ≤10 years group (P<0.05). Conclusions In overweight/obese T2DM patients with different DM durations,Dapagliflozin combined with insulin treatment shows a significant advantage in lowering blood glucose indices and improving pancreatic β-cell function,especially for patients with a shorter disease duration.

Objective:To evaluate the effect of s-ketamine on perioperative myocardial injury in patients undergoing liver transplantation.Methods:This was a prospective randomized controlled study. Sixty American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ patients, aged 18-64 yr, with New York Heart Association classⅠ-Ⅲ, undergoing elective liver transplantation with general anesthesia in our hospital from May to October 2023, were divided into 2 groups ( n=30 each) using a random number table method: s-ketamine group (group S) and control group (group C). In group S, s-ketamine was intravenously injected at a dose of 0.5 mg/kg after induction of anesthesia, followed by an infusion of 0.5 mg·kg -1·h -1 until the end of surgery. The equal volume of normal saline was given instead in group C. Central venous blood samples were collected after induction of anesthesia (T 0), at 30 min of anhepatic phase (T 1), 30 min of neopepatic phase (T 2), abdominal closure (T 3), 24 h after operation (T 4) and 72 h after operation (T 5) for determination of the concentrations of serum high-sensitivity cardiac troponin I, creatine kinase-MB isoenzyme, N-terminal pro-B-type natriuretic peptide, tumor necrosis factor-α, interleukin-6 (IL-6), IL-10 and high-mobility group protein B1 by enzyme-linked immunosorbent assay. The occurrence of adverse cardiac events during surgery and within 24 h after surgery, postoperative mechanical ventilation time, time of intensive care unit stay, and postoperative length of hospital stay were recorded. Results:Compared with group C, the concentrations of serum high-sensitivity cardiac troponin I, creatine kinase-MB isoenzyme, N-terminal pro-B-type natriuretic peptide, tumor necrosis factor-α and IL-6 at T 2-5 and high-mobility group protein B1 at T 2-4 were significantly decreased, the concentrations of serum IL-10 were increased at T 2-5, the incidence of myocardial ischemia was decreased, the mechanical ventilation time was shortened ( P<0.05), and no significant change was found in the time of intensive care unit stay and postoperative length of hospital stay in S group ( P>0.05). Conclusions:Intraoperative usage of s-ketamine can inhibit the inflammatory responses and reduce perioperative myocardial injury in the patients undergoing liver transplantation.

Objective:To explore the effect of esketamine on inflammatory cytokines and myocardial injury markers in children undergoing living-donor liver transplantation (LT).Methods:Considering the inclusion criteria, 50 children with biliary atresia were selected for living donor LT. They were equally randomized into two groups of control (C) and esketamine (E) (25 cases each). Esketamine 0.5 mg/kg was administered to group E during induction and continued at a dose of 0.5 mg·kg –1·h -1 after an induction of anesthesia. Group C provided the same dose of 0.9% sodium chloride injection during induction and then continued to pumping until the end of the procedure. Basic profiles of two groups were recorded. Hemodynamic parameters, such as heart rate (HR), mean arterial pressure (MAP) and central venous pressure (CVP), were monitored at 5 min of anesthesia induction (T 0), 30 min of anhepatic phase (T 1), immediately after repercussion (T 2), 30 min of neohepatic phase (T 3) and end of surgery (T 4) in both groups. Central venous blood samples were collected at T 0, T 1, T 3 and T 4. Serum levels of cardiac troponin I (cTnI), creatine kinase isoenzyme-MB (CK-MB) ,tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) were measured. The incidence of adverse cardiac events, postoperative mechanical ventilation time, ICU stay and hospitalization length were compared. Results:As compared with T 0, mean arterial pressure (MAP) at T 2 declined markedly in group E [(48.6±12.7) mmHg (1 mmHg=0.133 kPa) vs (55.6±10.7) mmHg, P<0.001] and C [(39.3±8.0) mmHg vs (53.2±9.4) mmHg, P<0.001 ] ;As compared with T 0, the TNF-α and IL-6 spiked at T 3 in group C [169.0 (207.1) ng/L vs 43.8 (26.4) ng/L, (132.63±51.75) ng/L vs (51.79±17.83) ng/L, P<0.001] and E [78.5 (138.8) ng/L vs 43.8 (26.4) ng/L, (87.44±32.17) ng/L vs (51.79±17.83) ng/L, P<0.001 ] ; In group C, the concentration of myocardial injury markers CK-MB and cTnI rose at T 3/T 4 compared with T 0[T 3 vs T 0: 5.7 (5.4) μg/L vs 4.0 (3.5) μg/L, 0.09 (0.08) μg/L vs 0.02 (0.02) μg/L; T 4 vs T 0: 5.3 (5.0) μg/L vs 4.0 (3.5) μg/L, 0.07 (0.08) μg/L vs 0.02 (0.02) μg/L, P<0.001 ]. In group E, the levels of CK-MB and cTnI were higher at T 3/T 4 than those at T 0[T 3 vs T 0: 7.0 (5.0) μg/L vs 4.6 (2.1) μg/L, 0.06 (0.09) μg/L vs 0.03 (0.04) μg/L; T 4 vs T 0: 5.4 (4.9) μg/L vs 4.6 (2.1) μg/L, 0.03 (0.06) μg/L vs 0.03 (0.04) μg/L; P<0.001].

Compared with group C, TNF-α and IL-6 decreased in E at T 3/T 4[T 3: 78.5 (138.8) ng/L vs 169.0 (207.1) ng/L, P=0.010; (87.44±32.17) ng/L vs (132.63±51.75) ng/L, P=0.017. T 4: 62.3 (118.3) ng/L vs 141.3 (129.2) ng/L, P=0.001; (74.34±26.38) ng/L vs (100.59±30.40) ng/L, P=0.002]. Compared with group C, cTnI decreased in E at T 3/T 4[0.06 (0.09) μg/L vs 0.09 (0.08) μg/L, P=0.014; 0.03 (0.06) μg/L vs 0.07 (0.08) μg/L, P=0.003]. Compared with group C, the mechanical ventilation time in group E decreased [195 (120) min vs 315 (239) min, P<0.001]. Compared with group C, the incidence of severe hypotension [16%(4/25) vs 48% (12/25), P=0.015 ], bradycardia [12% (3/25) vs 36 % (9/25), P=0.047 ], myocardial ischemia [4 % (1 /25) vs 24 % (6/25), P=0.042 ] and premature ventricular contractions [0 vs 4 %(1/25), P=0.312 ] decreased in group E. Conclusion:Intraoperative dosing of esketamine may suppress inflammatory reactions and alleviate perioperative myocardial injury in children undergoing living-donor LT.
