Objective To investigate the effect and safety of esketamine combined with general anesthesia and ultrasound-guided cervical plexus block in axillary endoscopic thyroidectomy.Methods The subjects of this study,112 female patients who underwent axillary endoscopic thyroidectomy in our hospital from January 2022 to October 2024,were randomly divided into an observation group and a control group,each with 56 cases.All patients were administered with ultrasound-guided cervical plexus block followed by general anesthesia.The observation group was injected with 0.1 mg/kg of esketamine prior to anesthesia induction and continuously pumped with esketamine at a rate of 0.1 mg/(kg·h)during the operation until sutures were completed,while the control group was administered with an equal volume of normal saline following the same procedure.The vital sign indicators[mean arterial pressure(MAP),heart rate(HR)and percutaneous arterial oxygen saturation(SpO2)]immediately after establishing electrocardiogram monitoring(T0),immediately before tracheal intubation(T1),immediately after tracheal intubation(T2),immediately after skin incision(T3)and immediately after the operation(T4)were compared between the two groups.Surgical related indicators such as propofol dosage,remifentanil dosage,and extubation time were also compared between them.Pain visual analogue scale(VAS)scores were performed on patients from the two groups at 1,6,12,and 24 h postoperatively.The 40-item quality of recovery score(QoR-40)was used before the surgeries and 1 d after surgeries to assess the patients.Adverse reactions were also compared.Results The difference was significant in terms of MAP,HR time effect in the two groups(F=24.63,F=20.11,P<0.05)and inter-group MAP,HR values(F=13.54,F=11.49,P<0.05).There were statistically significant differences in the interaction effects of MAP and HR between the two groups(F=4.10,F=3.46,P<0.05).The difference was not statistically significant in time,inter group,and interaction effects of SpO2(P>0.05).The dosage of propofol,remifentanil,and postoperative 1 d drainage in the observation group were less than those in the control group,the differences were statistically significant(P<0.05).The differences were not statistically signiciant in extubation time and awakening time between the two groups(P>0.05).The VAS scores at 1,6,12,and 24 h after operation in the observation groups were lower than those in the control group,the differences were statistically significant(P<0.05).Physical comfort,pain dimension ratings,and total score of the QoR-40 scale:1)those 1 d after operation were lower than those before operation in both groups(P<0.05);2)1 d after operation:those in the control group were lower than those in the observation group(P<0.05).The control group witnessed a remarkable decrease in QoR-40 emotional state rating 1 d after operation than it did before operation(P<0.05),while no significant change was seen by the observation group in this regard(P>0.05).The incidence of coughing after extubation in the observation group was lower than that in the control group(14.29%and 37.50%),the difference was statistically significant(P<0.05).The differences were not statistically signiciant in the incidence of other adverse reactions such as nausea,vomiting,dizziness,headache,respiratory depression,awakening restlessness and awakening delirium between the two groups(P>0.05).The total incidence of adverse reactions in the observation group was significantly lower than that in the control group(25.00%and 66.07%,P<0.05).Conclusion The application of esketamine combined with general anesthesia and ultrasound-guided cervical plexus block in axillary endoscopic thyroidectomy can significantly stabilize hemodynamics in patients,reduce postoperative pain,and promote postoperative recovery.It is worthy clinical application.

OBJECTIVE: To explore the therapeutic mechanism of Liushen Wan (LSW) against colitis-associated colorectal cancer (CAC) by network pharmacology. METHODS: TCMSP, BATMAN-TCM, CNKI, PubMed, Genecards, OMIM, and TTD databases were used to obtain the related targets of LSW and CAC. The common targets of LSW and CAC were obtained using Venny online website. The PPI network was constructed using Cytoscape 3.8.2 to screen the core targets of LSW in the treatment of CAC. GO and KEGG enrichment analysis were conducted using DAVID database. The therapeutic effect of LSW on CAC was evaluated in a C57BL/6J mouse model of AOM/DSS-induced CAC by observing the changes in body weight, disease activity index, colon length, and size and number of the tumor. HE staining and RT-qPCR were used to analyze the effect of LSW on inflammatory mediators. Immunohistochemistry and TUNEL staining were used to evaluate the effect of LSW on the proliferation and apoptosis of AOM/DSS-treated colon tumor cells. Immunohistochemistry and Western blotting were used to detect the effects of LSW on the expression of TLR4 proteins in CAC mice. RESULTS: Network pharmacology analysis identified 69 common targets of LSW and CAC, and 33 hub targets were screened in the PPI network. KEGG pathway enrichment analysis suggested that the effect of LSW on CAC was mediated by the Toll-like receptor signaling pathway. In the mouse model of AOM/DSS-induced CAC, LSW significantly inhibited colitis-associated tumorigenesis, reduced tumor number and tumor load (P < 0.05), obviously improved histopathological changes in the colon, downregulated the mRNA levels of proinflammatory cytokines, and inhibited the proliferation (P < 0.01) and promoted apoptosis of colon tumor cells (P < 0.001). LSW also significantly decreased TLR4 protein expression in the colon tissue (P < 0.05). CONCLUSION LSW can inhibit CAC in mice possibly by regulating the expression of TLR4 to reduce intestinal inflammation, inhibit colon tumor cell proliferation and promote their apoptosis.
