According to the anesthesia method, it was divided into the conventional group and the observation group, 40 cases in each group. The conventional group was anesthetized with propofol, midazolam, sufentanil, and atracurium sulfonate. The observation group was anesthetized with dexmedetomidine on the basis of the conventional group. The changes of vascular dynamics were compared between the two groups before induction (T0), induction 5 min (T1), surgery (T2), extubation immediately (T3) and 5 min after extubation (T4). The changes of immune function, inflammation and stress index in T0, T2 and 24h (T5) were compared between the two groups.Results: There were no significant differences in T0 vascular kinetics, immune function and inflammation stress between the two groups (P<0.05). Compared with T0, MAP, HR and CVP were significantly increased in the conventional group at T3 and T4 (P<0.05), and MAP, HR and CVP were significantly increased in the observation group at T3 (P<0.05). Compared with the conventional group in T3, T4, the MAP, HR, and CVP levels in the observation group at T3 and T4 were significantly lower than the conventional group (P<0.05). Compared with T0, the levels of immune function IgG, IgA, IgM and NK in T2 and T5 were significantly lower in the two groups (P<0.05). There was no significant difference in IgG, IgA, IgM and NK levels between T2 and T5 in the two groups (P>0.05). Compared with T0, the stress levels of NE and E were significantly increased at T2, and the levels of inflammatory factors TNF-αand Cor were significantly increased at T2 and T5 (P<0.05). Compared with the conventional group at T2, the NE and E levels in the observation group were significantly lower than those in the conventional group (P<0.05), and the levels of TNF-α and Cor in the observation group were significantly lower than those in the conventional group at T2 and T5 (P<0.05).Conclusions: Dexmedetomidine anesthesia has little effect on perioperative hemodynamics in elderly patients undergoing thoracoscopic lung cancer radical resection, and can relieve stress response, so it is worthy of clinical application.展开更多

文摘BACKGROUND Lung cancer(LC)is a global medical,social and economic problem and is one of the most common cancers and the leading cause of mortality from malignant neoplasms.LC is characterized by an aggressive course,and in the presence of disease recurrence risk factors,patients,even at an early stage,may be indicated for adjuvant therapy to improve survival.However,combined treatment does not always guarantee a favorable prognosis.In this regard,establishing predictors of LC recurrence is highly important both for determining the optimal treatment plan for the patients and for evaluating its effectiveness.AIM To establish predictors of disease recurrence after radical resection and adjuvant chemotherapy in patients with stage IIb-IIIa lung squamous cell carcinoma(LSCC).METHODS A retrospective case-control cohort study included 69 patients with LSCC who underwent radical surgery at the Orenburg Regional Clinical Oncology Center from 2009 to 2018.Postoperatively,all patients received adjuvant chemotherapy.Histological samples of the resected lung were stained with Mayer's hematoxylin and eosin and examined under a light microscope.Univariate and multivariate analyses were used to identify predictors associated with the risk of disease recurrence.Receiver operating characteristic curves were constructed to discriminate between patients with a high risk of disease recurrence and those with a low risk of disease recurrence.Survival was analyzed using the Kaplan-Meier method.The log-rank test was used to compare survival curves between patient subgroups.Differences were considered to be significant at P<0.05.RESULTS The following predictors of a high risk of disease recurrence in patients with stage IIb-IIa LSCC were established:a low degree of tumor differentiation[odds ratio(OR)=7.94,95%CI=1.08-135.81,P=0.049];metastases in regional lymph nodes(OR=5.67,95%CI=1.09-36.54,P=0.048);the presence of loose,fine-fiber connective tissue in the tumor stroma(OR=21.70,95%CI=4.27-110.38,P=0.0002);and fragmentation of the tumor solid component(OR=2.53,95%CI=1.01-12.23,P=0.049).The area under the curve of the predictive model was 0.846(95%CI=0.73-0.96,P<0.0001).The sensitivity,accuracy and specificity of the method were 91.8%,86.9%and 75.0%,respectively.In the group of patients with a low risk of LSCC recurrence,the 1-,2-and 5-year disease-free survival(DFS)rates were 84.2%,84.2%and 75.8%,respectively,while in the group with a high risk of LSCC recurrence the DFS rates were 71.7%,40.1%and 8.2%,respectively(P<0.00001).Accordingly,in the first group of patients,the 1-,2-and 5-year overall survival(OS)rates were 94.7%,82.5%and 82.5%,respectively,while in the second group of patients,the OS rates were 89.8%,80.1%and 10.3%,respectively(P<0.00001).CONCLUSION The developed method allows us to identify a group of patients at high risk of disease recurrence and to adjust to ongoing treatment.
文摘BACKGROUND Postoperative pain management and cognitive function preservation are crucial for patients undergoing thoracoscopic surgery for lung cancer(LC).This is achieved using either a thoracic paravertebral block(TPVB)or sufentanil(SUF)-based multimodal analgesia.However,the efficacy and impact of their combined use on postoperative pain and postoperative cognitive dysfunction(POCD)remain unclear.AIM To explore the analgesic effect and the influence on POCD of TPVB combined with SUF-based multimodal analgesia in patients undergoing thoracoscopic radical resection for LC to help optimize postoperative pain management and improve patient outcomes.METHODS This retrospective analysis included 107 patients undergoing thoracoscopic radical resection for LC at The Affiliated Cancer Hospital of Zhengzhou University and Henan Cancer Hospital between May 2021 and January 2023.Patients receiving SUF-based multimodal analgesia(n=50)and patients receiving TPVB+SUF-based multimodal analgesia(n=57)were assigned to the control group and TPVB group,respectively.We compared the Ramsay Sedation Scale and visual analog scale(VAS)scores at rest and with cough between the two groups at 2,12,and 24 h after surgery.Serum levels of epinephrine(E),angio-tensin Ⅱ(Ang Ⅱ),norepinephrine(NE),superoxide dismutase(SOD),vascular endothelial growth factor(VEGF),transforming growth factor-β1(TGF-β1),tumor necrosis factor-α(TNF-α),and S-100 calcium-binding proteinβ(S-100β)were measured before and 24 h after surgery.The Mini-Mental State Examination(MMSE)was administered 1 day before surgery and at 3 and 5 days after surgery,and the occurrence of POCD was monitored for 5 days after surgery.Adverse reactions were also recorded.RESULTS There were no significant time point,between-group,and interaction effects in Ramsay sedation scores between the two groups(P>0.05).Significantly,there were notable time point effects,between-group differences,and interaction effects observed in VAS scores both at rest and with cough(P<0.05).The VAS scores at rest and with cough at 12 and 24 h after surgery were lower than those at 2 h after surgery and gradually decreased as postoperative time increased(P<0.05).The TPVB group had lower VAS scores than the control group at 2,12,and 24 h after surgery(P<0.05).The MMSE scores at postoperative days 1 and 3 were markedly higher in the TPVB group than in the control group(P<0.05).The incidence of POCD was significantly lower in the TPVB group than in the control group within 5 days after surgery(P<0.05).Both groups had elevated serum E,Ang Ⅱ,and NE and decreased serum SOD levels at 24 h after surgery compared with the preoperative levels,with better indices in the TPVB group(P<0.05).Marked elevations in serum levels of VEGF,TGF-β1,TNF-α,and S-100β were observed in both groups at 24 h after surgery,with lower levels in the TPVB group than in the control group(P<0.05).CONCLUSION TPVB combined with SUF-based multimodal analgesia further relieves pain in patients undergoing thoracoscopic radical surgery for LC,enhances analgesic effects,reduces postoperative stress response,and inhibits postoperative increases in serum VEGF,TGF-β1,TNF-α,and S-100β levels.This scheme also reduced POCD and had a high safety profile.

Compared with the conventional group in T3, T4, the MAP, HR, and CVP levels in the observation group at T3 and T4 were significantly lower than the conventional group (P<0.05). Compared with T0, the levels of immune function IgG, IgA, IgM and NK in T2 and T5 were significantly lower in the two groups (P<0.05). There was no significant difference in IgG, IgA, IgM and NK levels between T2 and T5 in the two groups (P>0.05). Compared with T0, the stress levels of NE and E were significantly increased at T2, and the levels of inflammatory factors TNF-αand Cor were significantly increased at T2 and T5 (P<0.05).
