Chinese Journal of Pathophysiology 2000;0(11):-
AIM: To investigate the effects of c-fos antisense oligoneuleotide and p21 genetic transfection on the intimal proliferation of venous autografts. METHODS: The external jugule veins were autografted into common carotid arteries in the same side in 20 New Zealand rabbits, which were divided evenly into experimental and control group randomly. The transplanted veins of experimental group were immersed in the adenovirus - mediated p21 gene solution for 15 minutes just before anastomosis and coated with c-fos antisense oligoneucleotide glue gel just after anastomosis, while the control was only treated with empty vector. The transplanted vascular sample were taken at 2 weeks after operation. The intimal thickness (IT), degree of restenosis (DR), expression of proliferating cell nuclear antigen (PCNA), quantity of VSMC were determined by immunohischemistry. RESULTS: The IT , DR and expression of PCNA, VSMC were decreased, compared to control group. CONCLUSION: Transfection of c-fos antisense oligoneuleotide and p21 gene inhibits the intimal proliferation of venous antografs. [

International Eye Science 2010;10(1):23-29
AIM: To analyze single nucleotide polymorphisms (SNP) of primary open angle glaucoma- and metabolic syndrome-related genes in primary open angle glaucoma (POAG), in order to elucidate the roles of metabolic syndrome as a risk factor in POAG progress.METHODS: SNP genotypes and alleles of interleukin-6 (IL- 6), IL- 6 receptor (IL- 6R), dopamine D2 receptor (DRD2), beta-fibrinogen (FGB), peroxisome proliferator-activated receptor-γ2 (PPARG), transforming growth factor-β1 (TGF-β1), E-selectin (E-Sel), apolipoprotein A-5 (APOA5), C-reactive protein (CRP), ectonueleotide pyrophosphatase/ phosphodiesterase 1 (ENPP1), hepatic lipase (LIPC), adiponectin (ADIPOQ), paraoxonase 1 (PON1) and serine protease inhibitor E (SERPINE1) genes in POAG (n= 37) and normal control (n=100) groups were measured with ABI Prism 7900HT Fluorescence Quantitative PCR and TaqMan SNP Genotyping fluorescence probe kit.RESULTS: Genotypes and allele frequencies of IL- 6R, IL- 6, FGB, CRP, ENPP1, LIPC, ADIPOQ, PON1, and SERPINE1 in total POAG group were significantly different compared to the control group. CONCLUSION: Metabolic syndrome as a risk factor for POAG may be associated with genotypes and allele frequencies of the related genes.The corresponding gene expression and function can affect POAG progress, including roles of SERPINE1 in extracellular matrix, ENPP1 in insulin inhibition, IL- 6 in endogenous neuroprotection, IL- 6, IL- 6R and E-Sel in autoimmune response, LIPC and FGB in blood hyperviscosity syndrome, ADIPOQ in NOS/NO production, PON1 in vascular endothelial protection.
6.Study of procalcitonin and C-reactive protein in predicting enterog-enous bacterial infection among diarrheal patients after irinotecan chemotherapy
Chinese Journal of Clinical Oncology 2015;(7):382-385
Objective:To investigate procalcitonin and C-reactive protein levels in diarrheal patients who underwent irinotecan che-motherapy. Methods:Procalcitonin and C-reactive protein were detected among 85 diarrheal and 63 non-diarrheal patients after irinote-can chemotherapy. Results:According to WHO classification, patients without diarrhea are classified as grade 0, whereas patients with diarrhea can be classified as gradesⅠ-Ⅳ. In grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣpatients, the levels of procalcitonin were 0.29 ± 0.17, 0.30 ± 0.18, 0.36 ± 0.20, 1.24 ± 0.22, and 2.15 ± 0.26 ng/mL on the second day, respectively. However, on the fourth day, the procalcitonin lev-els were 0.28 ± 0.15, 0.30 ± 0.14, 0.34 ± 0.18, 2.00 ± 0.22, and 2.40 ± 0.28 ng/mL, respectively. Moreover, in grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣ, the levels of C-reactive protein were 6.06 ± 1.85, 6.12 ± 1.16, 6.20 ± 1.68, 22.62 ± 4.55, and 31.26 ± 5.23 mg/L on the second day, respectively. On the fourth day, the C-reactive protein levels were 5.80 ± 1.82, 5.94 ± 1.14, 6.15 ± 1.55, 30.52 ± 4.74, and 38.67 ± 5.68 mg/L, respectively. No significant difference was found between the procalcitonin and C-reactive protein levels of stagesⅠandⅡpa-tients (P>0.05), but a significant difference was found between stagesⅠ, andⅡpatients and stagesⅢandⅣpatients (P<0.05). Con-clusion: Monitoring levels of procalcitonin and C-reactive protein may be helpful in the early evaluation of the severity of diarrhea. This process has prognostic effect and can be used to assess whether patients have enterogenous bacterial infection. Monitoring the lev-els of these proteins has certain clinical value and can be used to guide early anti-infection therapy.
7.Rutin inhibits hydrogen peroxide-induced apoptosis through PI3K/AKT signaling pathway in human lens epithelial cells
Acta Universitatis Medicinalis Anhui 2015;(8):1107-1110
Objective To explore whether PI3K/ AKT signaling pathway participates in the inhibiting effect of Ru-tin on H2 O2-induced apoptosis in human lens epithelial cells( HLEC). Methods HLEC were divided into four groups: control group,H2 O2 group,rutin group,LY294002 group. Cell survival rates were determined by a 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay; cell apoptosis rates were monitored by flow cytometry with Annexin V-FITC and propidiun iodide(PI) staining. Western blot was used to measure the expres-sion levels of AKT and p-AKT. Results H2 O2 induced HLEC apoptosis. Compared with H2 O2 group,rutin group not only increased the expression lever of p-AKT,but also reduced cell apoptosis rate(P < 0. 01). In LY294002 group, LY294002, an inhibitor of PI3K/ AKT signaling pathway,could significantly block the change of these inde-xes produced by rutin group(P < 0. 01), but no significant change compared with H2 O2 group. Conclusion Rutin inhibits H2 O2-induced cell apoptosis and may be associated with PI3K/ AKT signaling pathway.

10.The Antitumor Effects of Mice Peritoneal Macrophages Transferred IL-2 and IFN-Y Gene in vivo
Chinese Journal of Cancer Biotherapy 1994;0(01):-
The eukaryotic expression vector pREP-8-IL-2 or and pREP-8-IFN-? was injected i.p. into mice by calcium phosphate coprecipitation method and IL-2 gene or IFN-? gene was successfully transfected into peritoneal M?s whose expression products could enhance the cytotoxicity of M?s, which secrete some TNF, IL-1 and NO, activate the nonspecific immunity and inhibit the growth of tumor effectively. In particular, IL-2 gene in combination with IFN-? gene transfection were successfully transfected into peritoneal M?s whose high expression products not only significantly enhance the M?s cytotoxicity and made it secrete high level TNF, IL-1 and NO, but also activated the CTLs of spleen and initiated specific immunity and nonspecific immunity . This would produce synergic antitumor effects. The results showed that IL-2 and IFN-? gene transfection produced more antitumor effects than IL-2 or IFN-? gene transfection alone.
