Objective To investigate the effects of saturated fatty acids and unsaturated fatty acids on proliferation and autophagy of human lung cancer cells. Methods The lung cancer cells A549 were treated with stearic acid (saturated fatty acid) and doconexent (DHA, unsaturated fatty acid), respectively, in concentrations of 0, 30, 60, 120 and 240μmol/L. MTT test and cell clone formation assay were performed to detect the proliferation of A549 cells. The morphology of A549 autophagy was observed by confocal laser scanning microscopy after A549 cells were treated with stearic acid or DHA for 24 hours. Western blotting assay was used to detect the expression of autophagy-related protein after A549 cells were treated with stearic acid or DHA for 12, 24 and 36 hours, respectively. Results 30-240μmol/L stearic acid or DHA both inhibited the proliferation of A549 cells (P<0.05). Both stearic acid and DHA induced autophagy of A549 cells, meanwhile, down-regulated Phospho-mTOR (ser2481) and up-regulated LC3Ⅱ/LC3Ⅰ of A549 cells (P<0.05). Conclusions Both saturated fatty acid and unsaturated fatty acid can inhibit the proliferation and induce autophagy of lung cancer cells. The mechanisms of autophagy may be related to Phospho-mTOR (ser2481) signaling pathway.

Objective: To establish colorectal cancer LoVo and SW620 cell lines that stably interfere with the expression of LINC01224, and to explore the effect of down-regulating the expression of LINC01224 on cell apoptosis. Methods: The GEPIA2 database was used to analyze the expression of LINC01224 in colorectal cancer tissues; qPCR method was used to detect the expression of LINC01224 in 10 human colorectal cancer cells. Three different LINC01224 siRNAs were respectively transfected into human colorectal cancer LoVo cells, and the LINC01224 shRNA lentiviral vector was constructed with the siRNA sequence with the most obvious inhibitory effect of LINC01224 expression. Recombinant lentiviral particles were packaged in HEK293 T cells and then infected with LoVo and SW620 cells. After selection by puromycin, the monoclonal cells that stably interfere with LINC01224 were obtained by limiting dilution method. MTS method detects cell proliferation ability, and flow cytometry detects cell apoptosis rate. Results: The expression of LINC01224 in colorectal cancer tissues was higher than that in normal colorectal tissues, and its expression in 10 types of colorectal cancer cells was also higher than that in normal colorectal epithelial cells HCOEPic. The inhibition rate of siRNA-3 on the expression of LINC01224 in LoVo cells was higher than that of siRNA-1 and siRNA-2. Therefore, siRNA-3 was chosen to design LINC01224 shRNA.Compared with the control group(sh-NC group), the expression level of LINC01224 in the LoVo and SW620 cells of the stable interference LINC01224 group(sh-LINC01224 group) was reduced(P<0.01), and the cell growth rate was slowed down(P<0.01), the rate of apoptosis also increased(P<0.01). Conclusion The shRNA lentiviral interference vector of LINC01224 is successfully constructed, which can stably infect LoVo and SW620 cells, down-regulate the expression of LINC01224 and induce cell apoptosis.

MethodsThe RA patients treated in the Department of Traditional Chinese Medicine and Rheumatology of the China-Japan Friendship Hospital from August 2022 to June 2024 were selected. The demographic information， clinical data， laboratory test results， and traditional Chinese medicine （TCM） symptom information were collected for syndrome differentiation， on the basis of which the characteristics and influencing factors of cold dampness obstruction syndrome were analyzed. ResultsA total of 258 RA patients were selected in this study， including 88 （34.1%） patients with cold dampness obstruction syndrome， 53 （20.5%） patients with dampness and heat obstruction syndrome， 31 （12.0%） patients with wind dampness obstruction syndrome， 29 （11.2%） patients with liver-kidney deficiency syndrome， 19 （7.4%） patients with Qi-blood deficiency syndrome， 14 （5.4%） patients with phlegm-stasis obstruction syndrome， 15 （5.8%） patients with stasis obstructing collateral syndrome and 9 （3.5%） patients with Qi-Yin deficiency syndrome. The patients were assigned into two groups of cold dampness obstruction syndrome and other syndromes. The group of cold dampness obstruction syndrome had lower joint fever， 28-tender joint count （TJC28）， and 28-joint disease activity score （DAS28）-C-reactive protein （CRP） and higher central sensitization， cold feeling of joints， fear of wind and cold， cold limbs， and abdominal distention than the group of other syndromes （P<0.05）. The binary logistic regression analysis showed that central sensitization （OR 5.749， 95%CI 2.116-15.616， P<0.001） and DAS28-CRP （OR 0.600， 95% CI 0.418-0.862， P=0.006） were the independent factors influencing cold dampness obstruction syndrome in RA. ConclusionCold dampness obstruction syndrome is a common syndrome in RA patients. It is associated with central sensitization， cold feeling of joints， abdominal distension and may be a clinical syndrome associated with central sensitization.
