Abstract
BACKGROUND Tumor growth rate (TGR), denoted as percentage change in tumor size per month, is a well-established indicator of tumor growth kinetics. The predictive value of early on-treatment TGR (EOT-TGR) for immunotherapy remains unclear. We sought to establish and validate the association of EOT-TGR with treatment outcomes in patients with advanced non-small-cell lung cancer (aNSCLC) undergoing anti-PD-1/PD-L1 (programmed cell death protein 1/programmed death-ligand 1) therapy. PATIENTS AND METHODS This bicenter retrospective cohort study included a training cohort, a contemporaneously treated internal validation cohort, and an external validation cohort. Computed tomography images were retrieved to calculate EOT-TGR, denoted as tumor burden change per month during a period between baseline and the first imaging evaluation after immunotherapy. Kaplan-Meier methodology and Cox regression analysis were conducted for survival analyses. RESULTS In the pooled cohort (n = 172), 125 patients (72.7%) were males; median age at diagnosis was 58 (range 28-79) years. Based on the training cohort, we determined the optimal cut-off value for EOT-TGR as 10.4%/month. Higher EOT-TGR was significantly associated with inferior overall survival [OS; hazard ratio (HR) 2.93, 95% confidence interval (CI) 1.47-5.83; P = 0.002], worse progression-free survival (PFS; HR 2.44, 95% CI 1.46-4.08; P = 0.001), and lower objective response rate (3.3% versus 20.9%; P = 0.040) and durable clinical benefit rate (6.7% versus 41.9%; P = 0.001). Results were reproducible in the two validation cohorts for OS and PFS. Among 43 patients who had a best response of progressive disease in the training cohort, those with high EOT-TGR had worse OS (HR 2.64; P = 0.041) and were more likely to progress due to target lesions at the first tumor evaluation (85.2% versus 0.0%; P <0.001). CONCLUSIONS Higher EOT-TGR was associated with inferior OS and immunotherapeutic response in patients with aNSCLC undergoing anti-PD-1/PD-L1 therapy. This easy-to-calculate radiologic biomarker may help evaluate the abilities of immunotherapy to prolong survival and assist in tailoring patients' management.

Abstract
Objective:To investigate the effect of Nasopore on nasal packing in functional endoscopic sinus surgery.Method:A total of 117 chronic rhinosiunsitis with or without nasal polyps patients undergone bilateral functional endoscopic sinus surgery and finished follow up visit were recruited. In accordance with various nasal packing materials in operation, patients were divided into Nasopore group, Sorbalgon group, Merocel group and Sorbalgon combined Mercel group. The VAS score was measured and differences were observed in patients of four groups in terms of subjective symptoms,post-operation adverse reaction and recovery of mucosa of operative nasal cavity in 2,4,8 and 12 weeks.Result:①The postoperative VAS symptoms score regarding nasal obstruction, nasal pain, head pressure feeling and discomfort in removal of the nasal packing in Nasopore group were significantly better than those in the other groups(P<0.05).②In Nasopore group,incidences of adverse reactions in epiphora, dysphagia, bleeding after removal nasal packing,surrounding mucosa scratches, nasal packing incarceration were significantly lower than that in the other groups(P<0.05). The incidences of fever,sneezing,bleeding in operation day and faint when removing nasal packing in four groups had no statistical differences(P> 0.05).③The postoperative Lund-Kennedy endoscopic mucosa morphology score in 2,4,8 and 12 weeks in four groups had no statistical differences(P> 0.05), and in each group the score was significantly lower as time changes(P<0.05).Conclusion:The Nasopore packing has definite hemostatic efficacy,little postoperative discomfort and nice mucosal healing outcome as well in patients after functional endoscopic sinus surgery.It indicates that Nasopore is an effective and reliable packing material in FESS.

Abstract
OBJECTIVE To investigate the binding of the chemosynthetic analogue of N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) FAM-Aca-SDKP to hepatic stellate cell-T6 (HSC-T6) cells and basic physical characteristics. METHODS The Ac-SDKP analogue short-peptide FAM-Aca-SDKP carrying green fluorescence was synthesized chemically. Quantitative real-time PCR was used to evaluate its effect on the secretion of HSC collagen and verify the consistency in the biological effect between FAM-Aca-SDKP and Ac-SDKP. A fluorescence microscope was used to observe the binding between FAM-Aca-SDKP and HSC-T6, and flow cytometry was used to evaluate the time-concentration effect of the binding between FAM-Aca-SDKP and HSC-T6. The t-test or rank sum test was used for the statistical analysis of different types of data. RESULTS After HSC-T6 was incubated with Ac-SDKP or FAM-Aca-SDKP for 24 hours, the expression of type I collagen in HSC-T6 was increased, when the action time was 0.5 hour, Ac-SDKP and FAM-Aca-SDKP caused a 30%-50% reduction in the expression of type I collagen. After HSC-T6 was incubated with FAM-Aca-SDKP, strong green fluorescence was observed on cell surface under a fluorescence microscope, and after Ac-SDKP was added, Ac-SDKP significantly reduced the fluorescence intensity on cell surface due to competitive inhibition. Flow cytometry showed that when the concentration of FAM-Aca-SDKP was 0-50μmol/L, the rate of fluorescence-positive cells rapidly increased from 0 to 12%; when the concentration was 50-100μmol/L, the rate of fluorescence-positive cells only increased from 12% to 14%; co-incubation with Ac-SDKP significantly reduced the rate of fluorescence-positive cells. The number of positive cells reached the peak at the 45-minute point of the incubation and then decreased gradually. CONCLUSIONS FAM-Aca-SDKP can bind to the surface of HSC-T6 cells, and this process has ligand-receptor binding characteristics such as competitive inhibition, saturability, and time-concentration effect.
