OBJECTIVEThe aim of this study was to identify six miRNAs expressed in plasma of patients with pancreatic cancer (PCa) and analyze their value as a diagnostic index of pancreatic cancer.

METHODSPlasma total RNAs were extracted from 30 PCa patients and 26 normal controls, and the abundance of six microRNAs was measured using real-time PCR. The possibility to combine them with CA19-9 as diagnostic biomarkers was analyzed.

RESULTSThe expression level of miR-21, miR-210, miR-155, miR-20a, miR-25 and miR-196a in plasma of patients with pancreatic cancer were 1.65×10(6), 5.98×10(4), 2.83×10(3), 3.47×10(6), 2.76×10(6), and 1.03×10(3) (copies/µl), while the normal controls were 4.08×10(5), 2.54×10(4), 8.55×10(2), 1.79×10(6), 9.32×10(5), and 4.67×10(2) (copies/µl), respectively, with a significant difference between the two groups (P < 0.05). The areas under the ROC curve of miR-21, miR-210, miR-155, miR-20a, miR-25 and miR-196a were 0.893, 0.810, 0.820, 0.766, 0.816 and 0.729, respectively. MiR-21 had the highest diagnostic value when it was used as diagnostic marker alone. The combination of miR-155 and miR-25 was more effective to distinguish PCa from normal than to be used alone, and the area under the ROC curve was 0.913 (95%CI 0.838-0.988) .When CA199 associated with miR -210 and miR-25, respectively, the areas under the ROC curves were 0.96 (95%CI was 0-1.0) and 0.942 (95% CI was 0.876-1.0), which were higher than CA199 alone (0.862, 95%CI was 0.748-0.975). There was a high improvement in diagnostic sensitivity and accuracy when miR-210 and miR-25 were combined with CA19-9, respectively.

CONCLUSIONSPlasma miR-21, miR-155, miR-25, miR-210 have diagnostic value for pancreatic cancer, and deserve further study.

Objective:To investigate the clinical efficacy and safety of domestic bortezomib in the treatment of patients with multiple myeloma (MM).Methods:The data of 60 MM patients treated with domestic bortezomib as the basic chemotherapy regimen in 5 medical centers of Qilu Hospital of Shandong University, Heze Municipal Hospital, Weifang People's Hospital, Binzhou Medical University Hospital, Zibo Central Hospital in Shandong Province from January 2018 to June 2019 were retrospectively analyzed, 52 of which were newly treated patients and 8 were relapsed and refractory patients. The patients received at least 2 courses of combined chemotherapy based on domestic bortezomib, and the efficacy was assessed and evaluated every 2 courses.Results:Follow-up until June 30, 2019 showed that some patients were unable to return to the hospital for regular treatment. All patients completed at least 2 courses of treatment, with an overall effective rate (ORR) of 76.7% (46/60); 42 patients completed 4 courses of treatment, with an ORR of 78.6% (33/42); 30 patients completed 6 courses of treatment, with an ORR of 86.7% (26/30); there was no significant difference in ORR of 2, 4 and 6 courses ( P > 0.05). The complete remission+very good partial remission rates of 2, 4 and 6 courses were 16.7% (10/60), 47.6% (20/42) and 66.7% (20/30), respectively, and the difference was statistically significant ( P < 0.01). During the treatment, the adverse events mainly included infection, peripheral neuropathy, herpes, digestive tract symptoms, hematologic toxicities and so on, which were light and moderate mostly, and most of them can be reversed. The total incidence of adverse events in patients who completed 2, 4 and 6 courses of treatment were 91.7% (55/60), 66.7% (28/42) and 36.7% (11/30), respectively. Conclusions:The domestic bortezomib-based chemotherapy regimens have good efficacy in the treatment of MM. The incidence of adverse events is similar to that of the original drug, and patients can tolerate the adverse events.

OBJECTIVETo compare the efficacy and toxicity of the chemotherapeutic regimen containing pirarubicin and mitoxantrone on the treatment of relapsed or refractory acute myeloid leukemia (AML) in adults.

METHODSIn this open prospective multicentre study, we randomly assigned patients with relapsed or refractory AML to receive TAE regimen (pirarubicin+cytarabine+etoposide) versus MAE regimen (mitoxantrone + cytarabine + etoposide). The efficacy and toxicity were compared between the two groups.

RESULTS56 patients entered this clinical trial. The complete remission (CR) rate on TAE arm was 79.0% versus 55.6% on MAE arm with the overall response (OR) rates of 86.8% versus 88.9%, respectively. The CR was higher on TAE arm (P=0.035) but with no significant difference between the two groups regarding the overall response (OR) rate. The regimens were well tolerated in both groups. Hematologic and non-hematologic toxicity were similar except relatively lower the mean dosage of G-CSF, red blood cells and platelets transfusion on TAE arm. No significant differences were seen between the two groups regarding the overall survival and relapse free survival rates.

CONCLUSIONTAE regimen might be an effective salvage therapy in patients with relapsed or refractory AML.

Methods:RNF43 gene was over-expressed and knockdown in mouse melanoma cells line B16-OVA by lentivirus infection; In vivo proliferation of mouse melanoma cells line B16-OVA in the Lv-Ctrl-OE, Lv-RNF43-OE, Lv-Ctrl-KD and Lv-RNF43-KD groups was detected by subcutaneous tumorigenesis assay in mice, and the expression levels of CD8 + T cells perforin and interferon γ (IFN-γ) in tumor immune microenvironment of melanoma were detected by flow cytometry; The expression levels of β-catenin and programmed death-ligand 1 (PD-L1) mRNA in cells were detected by quantitative real-time PCR assay; The effect of RNF43 on the transcriptional regulation of PD-L1 was detected by dual-luciferase reporter gene assay. Results:Stable RNF43 over-expressing and RNF43 knockdown mouse melanoma cells lines Lv-RNF43-OE and Lv-RNF43-KD were successfully constructed. The results of subcutaneous tumorigenesis experiment in mice showed that the tumor mass of the Lv-RNF43-OE group was (0.08±0.06) g, which was significantly smaller than that of the Lv-Ctrl-OE group [ (1.04±0.52) g], with a statistically significant difference ( t=3.71, P=0.032) ; The tumor mass of Lv-RNF43-KD group was (1.94±0.29) g, with no statistically significant difference ( t=-1.70, P=0.164) compared with that of the Lv-Ctrl-KD group (1.15±0.74) g. The flow cytometry results showed that the fluorescence intensity of CD8 + T cell perforin in the Lv-RNF43-OE group was 9 034 ± 2 628, which was significantly higher than that in the Lv-Ctrl-OE group (3 847 ±1 637), with a statistically significant difference ( t=-3.35, P=0.015) ; The fluorescence intensity of CD8 + T cell perforin in the Lv-RNF43-KD group was 966±247, which was significantly lower than that in the Lv-Ctrl-KD group (2 226±646), with a statistically significant difference ( t=3.16, P=0.034) ; The fluorescence intensity of IFN-γ of CD8 + T cell in the Lv-RNF43-OE group was 2 422±429, which was significantly higher than that of 1 688±324 in the Lv-Ctrl-OE group, with a statistically significant difference ( t=-2.73, P=0.034) ; The fluorescence intensity of IFN-γ of CD8 + T cell in the Lv-RNF43-KD group was 614 (454, 863), with a statistically significant difference ( Z=-1.96, P=0.050) compared with 1 159 (1 152, 2 068) in the Lv-Ctrl-KD group. The results of quantitative real-time PCR showed that the relative expression level of β-catenin mRNA in the Lv-RNF43-OE group was 0.67±0.16, which was significantly lower than that of 1.00±0.11 in the Lv-Ctrl-OE group, with a statistically significant difference ( t=2.98, P=0.041) ; The relative expression level of PD-L1 mRNA in the Lv-RNF43-OE group was 0.32±0.09, which was significantly lower than that of 1.00±0.09 in the Lv-Ctrl-OE group, with a statistically significant difference ( t=9.13, P=0.001). The results of the dual-luciferase reporter gene assay showed that the PD-L1 promoter luciferase activity in the pCMV6-NC, RNF43, RNF43+β-catenin and β-catenin groups were 1.00±0.00, 0.84±0.00, 1.49±0.00 and 1.57±0.03 ( F=2 218.33, P<0.001). Further pairwise comparison showed that compared with the pCMV6-NC group, PD-L1 promoter luciferase activity was significantly lower in the RNF43 group ( P<0.001) and significantly higher in the RNF43+β-catenin and β-catenin groups ( P<0.001; P=0.003) ; compared with the RNF43 group, PD-L1 promoter luciferase activity was significantly higher in the RNF43+β-catenin group ( P<0.001) . Conclusion:RNF43 may reduce the expression of PD-L1 mRNA in melanoma by inhibiting the expression of β-catenin and promote CD8 + T cell-mediated anti-tumor immune reaction.
