2.Alteration of intraocular pigment epithelium-derived factor and vascular endothelial growth factor in patients with diabetic retinopathy
International Eye Science 2007;7(1):23-26
AIM: To determine the aqueous, vitreous, serum levels of pigment epithelium-derived factor (PEDF)and vascular endothelial growth factor(VEGF)in patients with proliferative diabetic retinopathy(PDR), and to speculate on the source of the change in concentration and to discuss its clinical significance.METHODS:Forty-one eyes withproliferative diabetic retinopathy were included in the study, 16 of which were complicated by neovascularization of iris (NVI).Twenty-one eyes with idiopathic macular hole (MH)were as controls. The aqueous, vitreous, serum levels of PEDF and VEGF of all the groups were determined with ELISA. PEDF, VEGF and the levels in the three groups were compared with analysis of variance (ANOVA). The PEDF, VEGF concentrations in aqueous,vitreous and serum were analyzed with Pearson correlation test,and the correlation of PEDF and VEGF levels was also analyzed with Pearson correlation test.RESULTS:The aqueous levels of PEDF decreased significantly in sequence in groups of control, PDR without NVI, PDR with NVI. VEGF levels increased coordinately. The similar findings existed in vitreous samples. The PEDF,VEGF levels in aqueous were not correlated significantly with those in serum,but correlated positively with those in vitreous. The intraocular levels of PEDF had a negative correlation to those of VEGF.CONCLUSION:The reduction of intraocular PEDF level and elevation of intraocular VEGF level may play an important role in the occurrence and progression of PDR. In the development of PDR, the PEDF,VEGF levels in aqueous may be mainly effected by local pathological changes, as anti-angiogenic and pro-angiogenic factors, their unbalanced intraocular distribution may promote the angiogenesis of the iris and retina.
3.Study on effect of lycorine in inducing apoptosis of pulmonary carcinoma cell A549.
China Journal of Chinese Materia Medica 2015;40(16):3278-3282
To explore the effect of lycorine in inducing apoptosis of pulmonary carcinoma cell A549 and its mechanism. In the study, pulmonary carcinoma cell A549 were taken as the experimental subject and processed with different concentrations of lycorine (0, 0.5, 1.0, 2.0, 4.0 and 8.0 μmol x L(-1)). The MTT method was used to observe the cell proliferation. The apoptosis rate of A549 cells was determined by Annexin FITC/PI double staining. The microplate reader was used to detect the activities of Bcl-2, Bax and p53. The changes in mitochondrial membrane potential were measured by the flow cytometry. The expressions of apoptosis-related factors Bcl-2, Bax, p53 and Survivin were determined by Real-time PCR. The results showed that lycorine significantly inhibited the proliferation of A549 cells (P < 0.05), induced the apoptosis on A549 cells (P < 0.05), increased the activities of Bax and p53, reduced Bcl-2 activity and mitochondrial membrane potential, and notably changed the gene expressions of Bcl-2, Bax, p53 and Survivin (P < 0.05). In conclusion, lycorine can induce the apoptosis of A549 cells and be applied to treat pulmonary carcinoma. Its mechanism may be related to the activation of relevant factors in Bcl-2 signaling pathway.

Aim To investigate the effect on antagonism of benthiactzine and atropine against the function of muscarinic acetylcholine receptors by desensitization of nicotinic acetylcholine receptors. Methods The whole cell recording configuration of patch-clamp technique was used and the cell model was rat SCG neurons. To identify antagonists' antimuscarinic effect, mAchRs mediated IM-inhibition was measured and nicotine and oxotremorine were used. Results After de sensitization of nAChRs,the antimuscarinic effect ofboth benthiactzine and atropine decreased compared to the normal condition. The decreased antimuscarinic effect of benthiactzine was weaker than that of atro-pine. The antimuscarinic effect of both benthiactzine and atropine recovered gradually with the recovery of nAChRs from desensitization. Conclusion Desensiti-zation of nAChRs weakens the antagonists' antimuscarinic effect.

Objective To study the clinical effect of SCOFIX on thoracolumbar fracture.Methods The clinical data of twenty-five cases with thoracolumbar fracture treated with SCOFIX system were retrospectively anal- ysed.Results With six to twenty-two months follow-up,anterior height of compressed vertebral bodies was restored from 46.8 %(12%~60%)preoperatively to 92%(90%~100%)postoperatively,and that of posterior height was from 77.5%(26%~86%)to 96.7%(90%~100%).Cobb's angle was from 15.7?(12?~26?)preoperatively to 1.4?(0?~6?)postoperatively.Conclusion SCOFIX system was simple structured,easily used and strongly fixed, and it was a good system in spinal internal fixation and for deeply reseach.

Objective To observe the effects of hypoxia on the expression of connective tissue growth factor(CTGF)and matrix metalloproteinase 9(MMP-9)in lung fibroblasts at different time points.Methods Fibroblasts were cultured at hypoxic condition 0,1.5,3,6,12 h respectively.CTGF mRNA and MMP-9 mRNA level were detected in each group by reverse transcription-polymerase chain reaction(RT-PCR).The concen- tration of CTGF and MMP-9 protein in fibroblasts supernatant were determined using enzyme-linked im- munosorbent assay(ELISA).Results Hypoxia stimulated fibroblasts increased the level of CTGF mRNA with- in 1.5 h,and the levels remained at a plateau up to 6 h,and then decreased by 12 h.The level of MMP-9 mRNA increased significantly within 3 h,and the levels kept the trend for increasing.ELISA revealed that the levels of both CTGF and MMP-9 protein/cell in medium conditioned by fibroblasts exposed to hypoxia were maximal at 12 h.The level of MMP in the CTGF-Ab treated groups was significantly decreased compared to the untreated groups.Conclusions These findings suggest that hypoxia stimulates fibroblasts to release CTGF as a mitogen factor,which initiates the fibrosis cascade and airway remodeling by regulating the balance of extracellular ma- trix synthesis and degradation via MMP-9 which is secreted by fibroblast cells in response to CTGF.

Aim To investigate the effects of newly synthesized 2, 3-dimethyl-2-butylamine derivatives on potassium channels in cortical neurons from rats.Method On cultured cortical neurons, the influences of those novel compounds on I A and I K currents were evaluated using whole-cell patch clamp technique. Result On cortical neurons, these compounds (5),(6),(7),(9) showed no effects on outward potassium currents, while the compounds (4),(8) exhibited inhibition of I K currents. But on a rterial smooth muscle cells(SMCs), all the six compounds had potassium channels opening activities. While the other three compounds had no effects on potassium channels of SMCs, the compound (3) decreased the I K currents evoked on neu rons.Conclusion The novel 2,3-dimethyl-2-butylamine derivati ves had the different modulation of potassium channels on cortical neurons as SM Cs.
