Objective To explore the effects of advanced glyeosylation end products (AGEs) on the binding of hepatic nuclear factors to the human insulin receptor (hlR) gene promoter. Methods The oligonueleotides with hlR gene promoter activity, 42 bp (spanning -1 441 to -1 400, US1) or 146 bp (spanning -638 to -493), were artificially synthesized, with point mutations at 5 key G residues in 42 bp US1 m5 oligonucleotides. US1 and rat hepatic nuclear extracts (HNE) were incubated with glucose 6-phosphate, prior to non-competition and competition gel retardation electrophoresis. Results Competition gel retardation electrophoresis showed that the binding capacity of 32p-labeled US1 probe to HNE could be signifficantly decreased with increased US1. US1-AGEs and US1m5 decreased the binding of probe to HNE as well, but only partly affected the electrophoretie bands [1,5,10 ng US1-AGEs: (41.08±2.86)%, (27.64±2.92)%, (15.35±1.81%) vs (52.05±1.79)%]; 5,10 ng US1m5: (5.20± 1.03)%, (1.81±0.21)% vs (52.05±1.79)%]. AGEs formed on HNE could increase the binding of HNE to probe, along with nonspecifie binding increasing. Conclusion The impact of AGEs on hlR gene expression seems to be related to the effects on cis-elements and trans-acting factors.

Objective To investigate the clinical effects of phacoemulsification combined with goniosynechialysis on the treatment of primary angle-closure glaucoma (PACG) with cataract. Methods The retrospective review included 71 patients (98 eyes) with PACG and cataract treated in Tianjin Huanghe Hospital. Patients were underwent phacoemulsification and intraocular lens implantation combined goniosynechialysis. Among these patients, there were 21 males (30 eyes) and 50 females (68 eyes). Patients ranged in age from 53 to 94 years old, everage (73.94 ± 6.43) years old. They were divided into acute angle-closure glaucoma with cataract group (47 patients, 64 eyes) and chronic angle-closure glaucoma with cataract group (24 patients, 34 eyes). The visual acuity, intraocular pressure (IOP), anterior chamber angle, anterior chamber depth (CCT), topical and oral medications and surgical complications were observed before and after surgery in two groups. All the patients were followed up for 6 months. Results At the end of follow-up, postoperative visual acuity, IOP, CCT, anterior chamber angle and IOP-lowing medicine (topical and oral medications) were all improved in the two groups compared with those of preoperative levels (all P < 0.01). There were no statistical differences in preoperative or postoperative average visual acuity, IOP and anterior chamber angle between two groups (all P > 0.05). Values of CCT were significantly higher before and after operation in chronic angle-closure glaucoma with cataract group than those of acute angle-closure glaucoma with cataract group (P < 0.05). No drug-control rate of intraocular pressure was 76.5% (26/34) for chronic angle-closure glaucoma with cataract group than that of acute angle-closure glaucoma with cataract group (100%, 64/64). There was no need on topical medication in acute angle-closure glaucoma with cataract group. There were 14 eyes had corneal edema and 8 eyes appeared iris fibrous exudation in two groups, while no other serious complications. Conclusion For patients with PACG and cataract, the combined surgery of phacoemulsification and goniosynechialysis is a safe and effective therapy that can improve visual acuity and reduce IOP with fewer complications.

Objective To discuss the principle and the value of pereutanous microwave ablation for benign focal liver lesions. Methods Fourteen patients with 15 benign focal liver lesions received percutanous microwave ablation with 15G cool-tip microwave antenna. The maximum diameter of lesion was (26.2±13.6)mm (10 - 57 mm). Results Treatment sessions and total treatment time for single lesion were 1.4±0. 5 (1- 2) and (837±574)s (300- 2057 s). Follow-up range was 1- 35 months (median 6 months). The hepatic lesions were covered by coagulation necrosis region of ablation completely in all cases on contrast-enhanced at 1 month after ablation. The area of coagulation necrosis of ablation decreased on follow-up imaging in patients with more than 3 months follow-up. No complications happened in all cases. Side effects include pain (12/14) and fever (8/14) lasting I -9 days. The increase of serum transaminase decreased to normal at 1 week after ablation. Conclusions Percutanous microwave ablation has the merit of safety,minimal invasion, good ablation result and low incidence of side effect. Under the precondition of eareful choice of indication,pereutanous microwave ablation can be a selective treatment method for benign focal liver lesions.

Objective:To evaluate the role of nuclear factor erythroid 2-related factor/ heme oxygenase-1 (Nrf2/HO-1) signaling pathway in dexmedetomidine-induced reduction of oxygen-glucose deprivation and restoration (OGD/R) injury to microglia.Methods:BV-2 microglia were cultured in high-glucose DMEM culture medium supplemented with 10% fetal bovine serum in an normal culture incubator at 37 ℃ (5%CO 2-21%O 2-74 %N 2). The cells were seeded in 96-well plates at a density of 1.5×10 4 cells/ml (200 μl/well) or 6-well plates at a density of 2×10 5 cells/ml (2 ml/well) and divided into 5 groups ( n=30 each) using a random number table method: control group (group C), dexmedetomidine group (group D), group OGD/R, OGD/R+ dexmedetomidine group (group OGD/R+ D) and OGD/R+ dexmedetomidine+ ML385 group (group OGD/R+ D+ ML). The cells in group C were continuously cultured in a normal culture incubator for 26 h. In group D, dexmedetomidine at the final concentration of 10 μmol/L was added, cells were incubated for 2 h, and then were continuously incubated in a normal culture incubator for 26 h. In OGD/R, OGD/R+ D and OGD/R+ D+ ML groups, the culture medium was replaced with glucose-free DMEM culture medium, cells were cultured for 2 h in an incubator at 37 ℃ (5%CO 2-1%O 2-94 %N 2), the culture medium was replaced with high-glucose DMEM culture medium containing 10% fetal bovine serum and then the cells were cultured for 24 h in a normal incubator.Dexmedetomidine at the final concentration of 10 μmol/L was added at 2 h before OGD in OGD/R+ D and OGD/R+ D+ ML groups.Nrf-2 inhibitor ML385 at the final concentration of 4 μmol/L was added at 30 min before dexmedetomidine was added in group OGD/R+ D+ ML.Cells in 6 wells in each group were selected randomly for assessment of cell viability (by methyl thiazolyl tetrazolium assay) and apoptosis (using flow cytometry), and for determination of the concentrations of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-10 in the supernatant (using enzyme-linked immunosorbent assay), the expression of Nrf2 in nucleus, Nrf2 and HO-1(by Western blot ) and the expression of HO-1 mRNA (by real-time polymerase chain reaction). Results:Compared with group C, the cell viability was significantly decreased, cell apoptosis rate and concentrations of TNF-α, IL-6 and IL-10 in the supernatant were increased, and the expression of Nrf2 in nucleus, Nrf2, HO-1 and its mRNA was up-regulated in OGD/R and OGD/R+ D groups ( P<0.05), and no significant change was found in each parameter mentioned above in group D ( P>0.05). Compared with group OGD/R, the cell viability and IL-10 in the supernatant concentration were significantly increased, cell apoptosis rate and concentrations of TNF-α and IL-6 in the supernatant were decreased and the expression of Nrf2 in nucleus, Nrf2, HO-1 and its mRNA was up-regulated in group OGD/R+ D ( P<0.05), and no significant changes were found in the parameters mentioned above in group OGD/R+ D+ ML ( P>0.05). Compared with group OGD/R+ D, the cell viability and concentration of IL-10 in the supernatant were significantly decreased, cell apoptosis rate and concentrations of TNF-α and IL-6 in the supernatant were increased and the expression of Nrf2 in nucleus, Nrf2, HO-1 and its mRNA was down-regulated in group OGD/R+ D+ ML ( P<0.05). Conclusion:The mechanism by which dexmedetomidine alleviates OGD/R injury to microglia may be related to promoting the activation of Nrf2/HO-1 signaling pathway and inhibition of inflammatory responses.

OBJECTIVETo study the possible mechanism of protective effect for Baicalin on Bacillus pertussis (BP) infected brain tissue and the dose-effect relationship.

METHODSBrain tissues slices were divided into 7 groups: (1) the normal group; (2) the model group: infected by 10% BP; (3) the baicalin group, which was pretreated with baicalin, infected by BP and subdivided into 5 sub-groups according to different doses of baicalin used; (4) the glutamic acid group: cultured with glutamic acid; (5) the baicalin plus glutamic acid group; (6) the peroxide group: cultured with hydrogen peroxide; and (7) the baicalin plus peroxide group. The lactate dehydrogenase (LDH) content in the supernatant of culture was determined and quantitative protein determination was conducted.

RESULTSThe LDH releasing was higher in the model group, glutamic acid group and peroxide group as compared with that in the normal group, 15.10 +/- 4.89 u/g. protein (the same unit below), 15.49 +/- 5.66 and 16.54 +/- 5.47 vs 6.10 +/- 2.87 respectively (P < 0.01). After being pretreated with 0.25 mmol/L baicalin, LDH level decreased significantly to 8.65 +/- 2.43, which was significantly different from that in the model group (P < 0.01), LDH was also decreased in the baicalin plus glutamic acid group (9.93 +/- 2.89) and baicalin plus peroxide group (9.54 +/- 2.82), which was significantly lower than that in the glutamic acid group and the peroxide group respectively (P < 0.01).

CONCLUSIONPretreatment of baicalin has protective effect on BP caused nerve cell injury in rat brain slices, the protection is possibly related with the reduction of glutamic acid and hydrogen peroxide induced damage on nerve cells in vitro.
