AIM:To evaluate the effect of intrave-nous oxycodone administration at different timing on rebound pain following the resolution of inter-costal nerve blockade after thoracoscopic surgery.METHODS:A total of 114 patients undergoing elec-tive thoracoscopic surgery under general anesthe-sia between January and July 2024 were selected.The patients were aged 18 to 64 years,regardless of gender,with a BMI of 18 to 30 kg/m2,and classi-fied as ASA Ⅰ-Ⅱ.The patients were randomly divided into three groups using a random number table:control group(Group C),oxycodone administration at the end of surgery group(Group Q1),and oxyco-done administration 6 hours postoperatively group(Group Q2),with 38 patients in each group.Group C received a normal saline injection at the end of surgery,Group Q1 received an intravenous injec-tion of oxycodone 0.04 mg/kg at the end of sur-gery,and Group Q2 received an intravenous injec-tion of oxycodone 0.04 mg/kg at 6 hours postoper-atively.Patients in the three groups were treated with a postoperative intravenous self-control anal-gesic pump(PCIA).The occurrence of rebound pain was recorded,the time of the first analgesic pump press,the number of presses,the dosage of sufent-anil,and the need for rescue analgesia were also recorded.Numerical Rating Scale(NRS)scores at rest and during movement were recorded at 6,8,12,24,48 and 72 hours postoperatively.The Pitts-burgh Sleep Quality Index(PSQI)was used to as-sess the sleep quality of patients the night before surgery and for two nights postoperatively.Adverse reactions such as respiratory depression,postoper-ative nausea and vomiting(PONV),and pruritus were recorded.RESULTS:Compared with group C and Q1,the incidence of rebound pain,postopera-tive sufentanil consumption,effective compression frequency of PCIA from 0-24 hours after surgery,and the rate of rescue analgesia were lower in Groups Q2(P＜0.05);Compared to Group C,the NRS scores at rest and during movement at 8,12,and 24 hours postoperatively were significantly lower in Groups Q1 and Q2(P＜0.05).However,compared to Group Q1,Group Q2 exhibited lower NRS scores at rest and during movement at 8,12,and 24 hours postoperatively(P＜0.05).On the first postoperative night,the PSQI scores of patients in Group Q2 were significantly better than those in Groups C and Q1(P＜0.05).There was no statistical-ly significant difference in the incidence of PONV among the three groups(P＞0.05).No respiratory depression,drowsiness,or pruritus were observed postoperatively in any of the groups.CONCLUSION:Intravenous injection of 0.04 mg/kg oxycodone 6 hours after surgery can reduce the occurrence of rebound pain after intercostal nerve block resolu-tion in thoracoscopic surgery and improves pa-tients' sleep quality.

Alzheimer's disease(AD)is a preva-lent neurodegenerative disorder,characterized by the accumulation of beta-amyloid plaques,the phosphorylation of Tau proteins,and neuronal loss.As the global population ages,the incidence of AD is rising,and there is currently no effective cure.Herbal monomers have garnered interest due to their multifaceted pharmacological effects and low toxicity.This paper aims to provide a comprehen-sive overview of the mechanisms of Nrf2,NF-κB,PI3K/Akt,MAPK and other signalling pathways in the pathogenesis of AD.It also explores the modu-lation of these pathways by various TCM mono-mers,such as leptomeningine and tanshinone ⅡA,and details the research progress to date.For in-stance,Leptosine has been shown to activate Nrf2,thereby reducing oxidative stress,while Tanshinone ⅡA has been observed to inhibit the NF-κB path-way,leading to a reduction in inflammation.Not-withstanding the encouraging indications for the treatment of AD with TCM monomers,there are several challenges that must be addressed.Firstly,the precise mechanism of action remains to be ful-ly elucidated.Secondly,there are significant chal-lenges related to pharmacokinetics and bioavailabil-ity.Thirdly,the sample size of clinical studies is lim-ited and of variable quality.Fourthly,the quality control process is complex.Finally,interactions with other drugs must be taken into account.
