Objective To analyze the correlation between cardiac function and degree of coronary artery lesion in elderly patients with coronary heart disease. Methods A total of 110 elderly patients with coronary heart disease and 30 elderly people without coronary heart disease (non-coronary heart disease group) in the Third People's Hospital of Chengdu were selected for the study. Based on Gensini score, the patients with coronary heart disease were classified into mild, moderate and severe lesion groups. The echocardiographic indicators and myocardial injury indicators [cardiac troponin I (cTnI), creatine kinase (CK), creatine kinase isoenzyme (CK-MB)] were compared among the groups. The correlation between cardiac function indicators and degree of coronary artery lesion and the evaluation value of various indicators on severe coronary artery lesion were analyzed. Results The left ventricular ejection fraction (LVEF) was represented as severe lesion groupmoderate lesion group>mild lesion group> non-coronary heart disease group (P<0.05). LVEF showed a negative correlation with degree of coronary artery lesion (P<0.05), while LVEDD, LVESD, cTnI, CK and CK-MB all exhibited positive correlations with degree of coronary artery lesion (P<0.05). The combined detection of the above indicators demonstrated superior evaluation efficiency on severe coronary artery lesion compared to any single indicator (P<0.05). Conclusion There is a significant correlation between cardiac function and degree of coronary artery lesion in elderly patients with coronary heart disease. Comprehensive evaluation of these indicators is conducive to clinical disease risk stratification and individualized treatment.

Objective To observe the analgesic and rehabilitation effects of non μ-opioids anesthesia/analgesia(NΜOA)based on quadratus lumborum block(QLB)in emergency cesarean section under general anesthesia.Methods The retrospective study method was adopted,50 pregnant women undergoing hysterectomy under emergency general anesthesia in Langfang People's Hospital from January 2023 to December 2024 were selected as the study objects.The patients were divided into μ-opioids anesthesia/analgesia(ΜOA)group and NΜOA group according to different anesthesia/analgesia methods,25 cases in each group.ΜOA group received ΜOA;NΜOA group received NΜOA+QLB.Incisional pain and uterine contraction pain numerical rating scale(NRS)at out of the post-anesthesia care unit(T1),intravenous injection of oxytocin(T2),press the palace bottom 24 hours(T3),out of bed activity after operation(T4)and first analgesic time of incision pain,first analgesic time of uterine contraction pain,first no vomiting eating time,first exhaust time was observed and recorded.The incidence of vasoactive agents during the anesthetic period,rescue analgesia,rescue antiemetic,constipation,sleep disturbance after operation within 48 hours after operation were also recorded.Results The NRS scores at T1,T2,T3 and T4 in ΜOA group were significantly higher than those in NΜOA group(incisional pain 3.36±1.25 vs.1.12±0.97,3.68±1.18 vs.2.00±0.91,5.76±1.67 vs.4.20±1.00,4.48±1.29 vs.3.32±0.95;uterine contraction pain 3.72±1.49 vs.1.24±1.05,4.64±1.60 vs.3.04±1.27,7.56±1.71 vs.5.16±1.37,3.56±0.22 vs.2.56±0.16,all P<0.05).The first analgesic time of incision pain,first analgesic time of uterine contraction pain in ΜOA group were significantly less than that in NΜOA group(hours:3.06±2.02 vs.17.48±10.93,2.68±2.22 vs.15.80±11.39,both P<0.05),the first no vomiting eating time,first exhaust time in ΜOA group were significantly longer than those in NΜOA group(hours:8.56±0.57 vs.6.32±0.14,15.44±1.42 vs.10.16±1.14,both P<0.05),the incidence of vasoactive agents,rescue analgesia,rescue antiemetic,constipation,sleep disturbance after operation within 48 hours in ΜOA group were significantly higher than those in NΜOA group[64.0%(16/25)vs.32.0%(8/25),48.0%(12/25)vs.20.0%(5/25),44.0%(11/25)vs.16.0%(4/25),64.0%(16/25)vs.36.0%(9/25),60.0%(15/25)vs.32.0%(8/25),all P<0.05].Conclusion NΜOA based on QLB safely and effectively reduced side effects of μ-opioids and enhanced recovery compared to ΜOA on emergency cesarean section patients undergoing general anesthesia.

Objectives:This study aimed to observe the disintegration of clopidogrel and ticagrelor in vitro solution with different pH levels and in human digestive tract.Methods:(1)In vitro study:0.9% normal saline was mixed with hydrochloric acid and sodium bicarbonate respectively to mimic fasting gastric fluid,postprandial gastric fluid,gastric fluid after taking acid-inhibiting agent,acid-free gastric fluid and small intestine fluid.The disintegration of clopidogrel and ticagrelor in different pH solutions was observed.(2)In vivo study:12 patients who were admitted to the Department of Geriatric,Peking University First Hospital from 2022.11 to 2023.6 were included and underwent magnetic controlled capsule endoscopy.We observed the disintegration of clopidogrel(n=6)and ticagrelor(n=6)in the digestive tract.Results:(1)In vitro study:clopidogrel began to disintegrate earlier than ticagrelor([21.67±7.53]s vs.[40.00±6.33]s,P=0.001),but clopidogrel disintegrated more slowly than ticagrelor([23.00±9.38]min vs.[8.33±1.97]min,P=0.011).Clopidogrel disintegrated faster in alkaline solution than in acidic and neutral solution([11.50±4.95]min vs.[28.75±2.50]min,P=0.004),and the disintegration rate of ticagrelor in alkaline solutions is comparable to that in acidic and neutral solutions([7.00±1.41]min vs.[9.00±2.00]min,P=0.285).(2)In vivo study:In the study population,the morphology of clopidogrel and ticagrelor began to change after passing through the esophagus,of which 3 cases(clopidogrel 1 case,ticagrelor 2 cases)were in powder state when passing through the cardia,and the remaining 9 cases were basically intact when entering the stomach and completely disintegrated in the stomach.The complete disintegration time of Clopidogrel varied significantly among individuals,ranging from 8 to 33 min,with an average of(18.80±10.38)min,while the complete disintegration time of ticagrelor ranged from 3 to 6 min,with an average of(4.25±1.26)min.Clopidogrel disintegrated slower than ticagrelor(P=0.034).Conclusions:In vitro study,clopidogrel disintegrated more slowly than ticagrelor in solutions at different pH levels.Compared with clopidogrel,the disintegration rate of ticagrelor was less affected by pH.After oral administration of clopidogrel and ticagrelor,clopidogrel disintegrated more slowly than ticagrelor.The difference of complete disintegration time between individuals of ticagrelor was smaller and the disintegration rate was faster.

Objective:To investigate the application effect of quadratus lumborum block (QLB) combined with less opioid anesthesia analgesia in laparoscopic total hysterectomy (LTH) in elderly patients with uterine prolapse.Methods:A total of 86 elderly patients with uterine prolapse who received LTH in the Langfang People’s Hospital from Jan. 2021 to Oct. 2023 were prospectively selected and divided into group A ( n=42) and group B ( n=44) according to the random number table method. Group A received transversus abdominis block (TAPB) + general anesthesia, and group B received QLB combined with less opioid anesthesia + general anesthesia. The pain duration at different time points after operation [Numeric Rating Scale (NRS) method to evaluate resting incision and visceral pain] was compared between the two groups. The dosage of opioids and the additional analgesia rate were compared between the two groups. The sleep quality of the two groups before and 72 hours after operation was compared, and the adverse reactions of anesthesia were counted. Results:Compared with 6 h after operation, NRS scores of resting incision pain and visceral pain in the two groups decreased gradually at 12, 24 and 48 h after operation, and it was lower in group B than in group A. There were statistically significant differences between groups ( P<0.05) . Dosage of sufentanil and remifentanil in group B was lower than that in group A, and the postoperative additional analgesia rate in group B (9.09%) was lower than that in group A (28.57%) ( P<0.05) . 72 hours after surgery, the sleep efficiency and total sleep time of patients in both groups were lower than those before surgery, and they were higher in group B than in group A; The awakening time and number of awakenings in both groups were higher than those before surgery, while they were lower in group B than in group A ( P<0.05) . The total incidence of adverse reactions in group B was 4.76% (2/44) , lower than 23.81% (10/42) of group A ( P<0.05) . Conclusion:QLB combined with less opioid anesthesia analgesia can effectively reduce the degree of incision and visceral pain after LTH in elderly patients with uterine prolapse, reduce the amount of opioids used during operation and the rate of additional analgesia, and reduce the incidence of adverse reactions of anesthesia.

Background: Nasopharyngeal carcinoma (NPC) is characterized by high programmed death-ligand 1 (PD-L1) expression and abundant infiltration of non-malignant lymphocytes, which renders patients potentially suitable candidates for immune checkpoint blockade therapies. Palate, lung, and nasal epithelium clone (PLUNC) inhibit the growth of NPC cells and enhance cellular apoptosis and differentiation. Currently, the relationship between PLUNC (as a tumor-suppressor) and PD-L1 in NPC is unclear. Methods: We collected clinical samples of NPC to verify the relationship between PLUNC and PD-L1. PLUNC plasmid was transfected into NPC cells, and the variation of PD-L1 was verified by western blot and immunofluorescence. In NPC cells, we verified the relationship of PD-L1, activating transcription factor 3 (ATF3), and β-catenin by western blot and immunofluorescence. Later, we further verified that PLUNC regulates PD-L1 through β-catenin. Finally, the effect of PLUNC on β-catenin was verified by co-immunoprecipitation (Co-IP). Results: We found that PLUNC expression was lower in NPC tissues than in paracancer tissues. PD-L1 expression was opposite to that of PLUNC. Western blot and immunofluorescence showed that β-catenin could upregulate ATF3 and PD-L1, while PLUNC could downregulate ATF3/PD-L1 by inhibiting the expression of β-catenin. PLUNC inhibits the entry of β-catenin into the nucleus. Co-IP experiments demonstrated that PLUNC inhibited the interaction of DEAD-box helicase 17 (DDX17) and β-catenin. Conclusions PLUNC downregulates the expression of PD-L1 by inhibiting the interaction of DDX17/β-catenin in NPC.
