Objective To study the effect of lentivirus-mediated CCL5-RNAi on the biological behaviors of human breast cancer cells. Methods CCL5-specific siRNA gene was synthesized and cloned into the recombinant lentiviral vector, pGCSIL-GFP. Human high-metastatic breast cancer cells, MDA-MB-231, were infected by CCL5-siRNA recombinant lentivirus, which was set as KD group. Cells infected with CCL5-NC was as NC group, and cells cultured was as CON group. The expression of CCL5 mRNA and protein in MDA-MB-231 cells was detected by RT-PCR and western blot, respectively. Cell growth suppression and cell cycle was observed by MTT assay and fluorescence activated cell sorting (FACS). Colony formation and migration ability were determined by colony-rorming assay and Boyden chamber method. Results After infection of CCL5-siRNA recombinant lentivirus, the expression level of CCL5 mRNA and protein in MDA-MB-231 cells as well as the colony formation and migration ability decreased significantly, but cell's proliferation was not affected obviously. Compared with MDA-MB-231 (0.88± 0.15) and MDA-MB-231/CCL5-NC (1.00±0.07) cells, the expression of CCL5 mRNA in MDA-MB-231/ CCL5-siRNA decreased to 0.18±0.03, P<0.01. Compared with MDA-MB-231/CCL5-NC (1.82±0.18) cells, the expression of CCL5 protein in MDA-MB-231/CCL5-siRNA decreased to 0.33±0.13, P <0.01. Colony-forming assay and Boyden chamber method showed that the colony formation and migration ability of MDA-MB-231/CCL5-siRNA decreased markedly (P<0.05). The clone count in KD group was (0.33± 0.10), which was a significant decrease from (0.97±0.09) (NC group) and (1.04±0.07) (CON group), P<0.05. The number of cells that migrated through the chamber membrane of KD group (38± 15) was less than that of NC group (77±11, P <0.05) and CON group (69±9, P <0.05). However, MTT assay and FACS revealed that the proliferation of MDA-MB-231/CCL5-siRNA was not different from MDA-MB-231/CCL5-NC and MDA-MB-231 (P>0.05), the proliferation index (PI) of group KD, NC and CON were (0.48±0.02), (0.44±0.05) and (0.47±0.02) respectively. The difference was not statistically significant by multiple comparison (P>0.05). Conclusion CCL5-specific siRNA can specifically suppress the colony formation and migration of human high-matastatic breast cancer cells.

Objective: To investigate the efficacy of prussian blue (PB) or its combination with hemoperfusion (HP) in the treatment of acute thallium poisoning. Methods: Forty-seven patients with acute thallium poisoning with complete data hospitalized in the 307th Hospital of PLA from September 2002 to December 2017 were enrolled, and they were divided into mild poisoning group (blood thallium < 150 μg/L, urinary thallium < 1 000 μg/L) and moderate-severe poisoning group (blood thallium ≥ 150 μg/L, urinary thallium ≥ 1 000 μg/L) according to the toxic degrees. All patients were given symptomatic supportive treatments such as potassium supplementation, catharsis, vital organ protections, neurotrophic drugs, and circulation support. The mild poisoning patients were given PB with an oral dose of 250 mg·kg^-1·d^-1, while moderate-severe poisoning patients were given PB combined HP continued 2-4 hours each time. The PB dose or frequency of HP application was adjusted according to the monitoring results of blood and urine thallium. Data of gender, age, pain grading (numeric rating scale NRS), clinical manifestations, blood and urine thallium before and after treatment, length of hospitalization and prognosis were collected. Results: Of the 47 patients, patients with incomplete blood and urine test results, and used non-single HP treatment such as plasmapheresis and hemodialysis for treatment were excluded, and a total of 29 patients were enrolled in the analysis. ①Among 29 patients, there were 20 males and 9 females, median age of 40.0 (34.0, 49.0) years old; the main clinical manifestations were nervous system and alopecia, some patients had digestive system symptoms. There were 13 patients (44.8%) in the mild poisoning group with painless (grade 0) or mild pain (grade 1-3) with mild clinical symptoms, the length of hospitalization was 17.0 (14.2, 21.5) days.
