Objective To explore the effect of advanced glycosylation end products (AGEs) on expression of connective tissue growth factor (CTGF) in cultured rat vascular smooth muscle cells (VSMCs) and the mechanism of accelerated atherosclerosis in diabetes. Methods VSMCs were isolated and cultured from the thoracic aorta of rat. Reverse transcription polymerase chain reaction (RT-PCR) and Western immunoblot analysis were used to detect the expression level of CTGF mRNA and protein. Results The expression of CTGF mRNA and protein were increased by AGE-BSA in the time- and dose-dependent manners(P<0.05). Conclusions AGEs may increase the expression activity of CTGF in cultured vascular smooth muscle cells.

Objective:To study the effect of psoralen on the proliferation, invasion and migration of HTB-47 and CRL-1932 renal cancer cells cultured in vitro, and to further explore the internal mechanism of psoralen inhibiting renal cancer.Methods:The experimental group was HTB-47 and CRL-1932 renal cancer cells treated with dimethyl sulfoxide solution containing 30 μg/ml psoralen, and the control group was renal cancer cells treated with dimethyl sulfoxide. Scratch test, CCK8, Transwell, and Western blot were used to detect the effect of psoralen on renal cancer cells.Results:Compared with the control group, the proliferation, invasion and migration of renal cancer cells treated with psoralen in the experimental group were significantly inhibited. In the renal cancer cells treated with psoralen, the protein expression levels of MKI67, PCNA, MMP2 and MMP9 were significantly decreased (all P<0.05). Conclusions:Psoralen can significantly inhibit the proliferation, invasion and migration of HTB-47 and CRL-1932 renal cancer cells in vitro. The mechanism may be to inhibit the progression of renal cancer by regulating MKI67, PCNA, MMP2 and MMP9.

Objective To investigate the short-term efficacy and security of combined treatment of iodine-125 seeds and transeathether arterial chemoembolization in liver neoplasms. Methods Transcathether arterial chemoembolization underwent in experimental group (28 cases) with liver neoplasm. The treatment plan was formulated with treatment planning system and a median of 25 seeds per patient (range, 15--40 seeds) were implanted under CT or B ultrasound guidance in 2 weeks after the procedure. Transcathether arterial ehemoembolizafion underwent after the implanted regularity. Blood routine and liver function were detected before and after the procedure. X ray check and abdomen CT scan were performed each 2 months. Control group (32 cases) were treated with transcathether arterial chemoembolization alone. Analysis of variance and Chi-square test were used for statistics. Results All seeds were released to the target places successfully and no seed was found to be lost or migrated in experimental group. Transient elevation of the serum ALT and AST but recovered in 2 week. WBC, Hb, IgA and IgG were showed no significant changes. The severe complication was not found in those eases. The responsive rate of tumor was 75.0% (21/28), 37.5% (12/32) in experimental group and control group, respectively(X2 = 8.485,P = 0.004). The survival rate of 6 months was 92.9% (26/28), 75.0% (24/32) in experimental group and control group, respectively(X2=2.263,P=0.132). The surviral rate of 12 months was 72.0% (18/25), 43.3% (13/30) in experimental group and control group, respectively (X2 = 4.556, P=0.033). Conclusion It is simple, feasible, safe and short-termly effective for liver neoplasms in treatment combined iodine-125 seeds implantation with transcathether arterial chemoembolization.

OBJECTIVETo explore the feasibility of genetic algorithm (GA) on multiple objective blending technology for extractions of Cortex Fraxini.

METHODAccording to that the optimization objective was the combination of fingerprint similarity and the root-mean-square error of multiple key constituents, a new multiple objective optimization model of 10 batches extractions of Cortex Fraxini was built. The blending coefficient was obtained by genetic algorithm. The quality of 10 batches extractions of Cortex Fraxini that after blending was evaluated with the finger print similarity and root-mean-square error as indexes.

RESULTThe quality of 10 batches extractions of Cortex Fraxini that after blending was well improved. Comparing with the fingerprint of the control sample, the similarity was up, but the degree of variation is down. The relative deviation of the key constituents was less than 10%.

CONCLUSIONIt is proved that genetic algorithm works well on multiple objective blending technology for extractions of Cortex Fraxini. This method can be a reference to control the quality of extractions of Cortex Fraxini. Genetic algorithm in blending technology for extractions of Chinese medicines is advisable.

Fusobacterium nucleatum (F. nucleatum) is an early pathogenic colonizer in periodontitis, but the host response to infection with this pathogen remains unclear. In this study, we built an F. nucleatum infectious model with human periodontal ligament stem cells (PDLSCs) and showed that F. nucleatum could inhibit proliferation, and facilitate apoptosis, ferroptosis, and inflammatory cytokine production in a dose-dependent manner. The F. nucleatum adhesin FadA acted as a proinflammatory virulence factor and increased the expression of interleukin(IL)-1β, IL-6 and IL-8. Further study showed that FadA could bind with PEBP1 to activate the Raf1-MAPK and IKK-NF-κB signaling pathways. Time-course RNA-sequencing analyses showed the cascade of gene activation process in PDLSCs with increasing durations of F. nucleatum infection. NFκB1 and NFκB2 upregulated after 3 h of F. nucleatum-infection, and the inflammatory-related genes in the NF-κB signaling pathway were serially elevated with time. Using computational drug repositioning analysis, we predicted and validated that two potential drugs (piperlongumine and fisetin) could attenuate the negative effects of F. nucleatum-infection. Collectively, this study unveils the potential pathogenic mechanisms of F. nucleatum and the host inflammatory response at the early stage of F. nucleatum infection.
