Objective To evaluate the feasibility and safety of thoracoscopic radical resection of non-small cell lung cancer(NSCLC)patients under laryngeal mask anesthesia. Methods A total of 40 patients with NSCLC from March to August 2016 in NanFang Hospital of Southern Medical University were recruited and divided into two groups,the laryngeal mask anesthesia(n=20)and the intubation anesthesia group(n=20). Patients from two groups were followed up. Post-operativerecovery ,systemic inflammation response and quality of life were assessed. Results There was no significant difference between the laryngeal mask anesthesia and the intubation anesthesia group in the operation time ,the lowest oxygen saturation ,the maximum end-tidal carbon dioxide partial pressure and the surgical field and the satisfaction of anesthesia and blood loss. Post-operative time to eat ,postoperative use of antibiotics , postoperative hospital stay and drainage time were much shorter in the laryngeal mask anesthesia group ,which also had lowerlevel of white blood cells ,neutrophils and C-reactive protein. Patients with NSCLC undergoing laryngeal mask anesthesia had much higher scores in the quality of life evaluation. Conclusion Thoracoscopic radical resectionunder laryngeal mask anesthesia is safe and feasible for NSCLC patients. It has advantages in reducing the systemic inflammatory response ,accelerating the recovery rate and improving postoperative life quality.

Objective:To investigate the role of sterol regulatory element binding protein-1 (SREBP1) in atorvastatin-induced reduction of nucleotide-binding oligomerization domain-like receptor protein 1 ( NLRP1 ) inflammasome expression. Methods:THP-1 cells were treated with phorbol 12-myristate 13-acetate (160 nmol/L) for 12 h to be differentiated into macrophages. The medium was then replaced with serum-free medium containing lipopolysaccharide and ( or ) atorvastatin. The mRNA expression of NLRP1 and SREBP1 were detected by Real-time PCR. The protein expression of NLRP1 and SREBP1 were determined by Western blot. Furthermore, we observed the effect of SREBP1 siRNA on atorvastatin-induced reduction of NLRP1 expression. Results:Atorvastatin inhibited the mRNA and protein expression of NLRP1 and SREBP1 in the THP-1 macrophages. SREBP1 siRNA showed no significant difference on lowering NLRP1 expression when compared with atorvastatin. Treating cells with SREBP1 siRNA and atorvastatin at the same time resulted in more obvious reduction of NLRP1 expression than single use of SREBP1 siRNA or atorvastatin. Conclusion:Atorvastatin might exert anti-inflammatory effect by repressing NLRP1 expression through the SREBP1 path-way.

Objective:To investigate the correlation of preoperative peripheral lymphocyte-to-monocyte ratio(LMR)with the biochemical relapse and prognosis in prostate cancer(PCa)patients treated with endocrine therapy after radical prostatectomy(RP).Methods:Clinical data of 306 prostate cancer patients treated with endocrine therapy after radical prostatectomy were retrospectively analyzed in our hospital from June 2008 to June 2019.The end point of observation was biochemical relapse-free survival(RFS)in all patients receiving RP.The best cutoff value of preoperative LMR was calculated by receiver operating characteristic(ROC)curve.All patients were divided into the high LMR group(LMR≥2.8, n=93, 30.4%)and the low LMR group(LMR<2.8, n=213, 69.6%). The differences in clinical indicators of PCa were compared between high and low LMR groups.CoX regression model on the risk ratio of single and multiple factors were used to analyze the survival effect of preoperative LMR on the prognosis of PCa patients undergoing endocrine therapy after operation.Results:The median follow-up time was ranged from 4 to 132 months.The area under the ROC curve of LMR was 0.582(95% CI: 0.511-0.652, P<0.05), and the cutoff value of the preoperative LMR was 2.8, which was significantly associated with clinical T stage( P=0.023)and lymphatic metastasis( P=0.031). Kaplan-Meier analysis demonstrated that the low LMR group had a short RFS and a poor prognosis(31.0 months vs.38.5 months)than those in the high LMR group( P<0.05). Lymphatic metastasis and preoperative LMR were independent predictors for RFS in PCa patients treated with endocrine therapy after radical prostatectomy. Conclusions:Preoperative peripheral LMR can be used as an auxiliary indicator of the prognosis in PCa patients treated with endocrine therapy after radical prostatectomy.

Objective:To investigate the correlation between the waiting time for radiotherapy after induction chemotherapy and the prognosis of locally intermediate and advanced nasopharyngeal carcinoma, as well as its optimal time.Methods:Retrospective analysis of 101 patients with locally intermediate and advanced nasopharyngeal carcinoma admitted to the Fifth Affiliated Hospital of Sun Yat-sen University from 2017 to 2020 was performed. All patients received at least 2 courses of induction chemotherapy followed by radical radiotherapy. The waiting time for radiotherapy was defined as the time from the end of induction chemotherapy to the start of the first radiotherapy. The relationship between waiting time for radiotherapy and other factors (age, gender and stage, etc.) with progression-free survival (PFS), local recurrence-free survival (LRFS) and distant metastasis-free survival (DMFS) was analyzed through Cox model. The median waiting time for radiotherapy with 3 weeks was used as the boundary, and all patients were divided into ≤3 weeks and>3 weeks groups. The PFS, LRFS and DMFS between two groups were compared using Kaplan-Meier survival analysis. P<0.05 was considered as statistical significance. Results:Cox-regression analysis showed that the waiting time was correlated with PFS, LRFS, and DMFS (all P<0.05). Kaplan-Meier survival analysis suggested that the PFS, LRFS and DMFS in the ≤3 weeks group were significantly better than those in the >3 weeks group (all P<0.05). Under the premises of the T 3 stage, N 2 stage and the increased EB virus DNA replication levels before treatment, the PFS, LRFS and DMFS in the ≤3 weeks group were significantly better than those in the >3 weeks group (all P<0.05). Conclusions:The waiting time for radiotherapy is one of the factors affecting clinical prognosis of locally intermediate and advanced nasopharyngeal carcinoma. The earlier the time, the better the prognosis. Radiotherapy should be delivered within 3 weeks.

Pentraxin 3 (PTX3) was identified as a marker of the inflammatory response and overexpressed in various tissues and cells related to cardiovascular disease. Honokiol, an active component isolated from the Chinese medicinal herb Magnolia officinalis, was shown to have a variety of pharmacological activities. In the present study, we aimed to investigate the effects of honokiol on palmitic acid (PA)-induced dysfunction of human umbilical vein endothelial cells (HUVECs) and to elucidate potential regulatory mechanisms in this atherosclerotic cell model. Our results showed that PA significantly accelerated the expression of PTX3 in HUVECs through the IkappaB kinase (IKK)/IkappaB/nuclear factor-kappaB (NF-kappaB) pathway, reduced cell viability, induced cell apoptosis and triggered the inflammatory response. Knockdown of PTX3 supported cell growth and prevented apoptosis by blocking PA-inducted nitric oxide (NO) overproduction. Honokiol significantly suppressed the overexpression of PTX3 in PA-inducted HUVECs by inhibiting IkappaB phosphorylation and the expression of two NF-kappaB subunits (p50 and p65) in the IKK/IkappaB/NF-kappaB signaling pathway. Furthermore, honokiol reduced endothelial cell injury and apoptosis by regulating the expression of inducible NO synthase and endothelial NO synthase, as well as the generation of NO. Honokiol showed an anti-inflammatory effect in PA-inducted HUVECs by significantly inhibiting the generation of interleukin-6 (IL-6), IL-8 and monocyte chemoattractant protein-1. In summary, honokiol repaired endothelial dysfunction by suppressing PTX3 overexpression in an atherosclerotic cell model. PTX3 may be a potential therapeutic target for atherosclerosis.
