? AIM: To investigate the efficacy and safety of phacoemulsification combined with intraocular lens implantation in the treatment of shallow anterior chamber with cataract.?METHODS: Retrospective case series. From February 2014 to July 2015 in our hospital,65 eyes in 65 patients with cataract were enrolled and divided into mild and high risk of shallow anterior chamber group. Best-corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , central anterior chamber dept ( CACD ) , angle opening distance ( AOD ) , complications pre- and post treatment, were observed and analyzed as outcome measures.?RESULTS: In this study, the mild shallow anterior chamber group included 34 eyes; postoperative BCVA were improved in 29 eyes, with 4 eyes remaining stable and decreased in 1 eye; BCVA was improved in 16 eyes, with 10 eyes remaining stable and decreased in 5 eyes in high risk of shallow anterior chamber group postoperatively. BCVA had a better prognosis in the mild shallow anterior chamber group than another group ( t=-2. 956, P<0. 05). Meanwhile, IOP decreased by 5. 71± 2. 07mmHg and CACD increased by 1. 37 ± 0. 38mm in the mild shallow anterior chamber group, by 9. 77±4. 04mmHg and 1. 67±0. 43mm respectively in high risk group, and the difference has statistical significance ( t=-5. 02,-3. 04; P<0. 05). The mean preoperative nasal AOD500 was 200. 57± 33. 74μm, and they were 346. 62 ± 101. 37μm and 410. 75 ± 137. 48μm and 398. 69 ± 122. 28μm respectively at postoperative 1d, 1 and 3mo, and all nAOD500 comparing with preoperative were increased obviously, and the difference has statistical significance (F=203. 75, P<0. 01). And AOD500 at temporal, superior and inferior presented similar trends. Complications were corneal edema ( 5 eyes ) , transient intraocular hypertension ( 2 eyes ) , posterior capsular opacification ( 4 eyes ) , and posterior capsular rupture (1 eye).?CONCLUSION:Micro incision cataract surgery is useful, effective and safe in patients with cataract and shallow anterior chamber which can stabilize or improve BCVA, reduce IOP, deepen CACD and open the anterior chamber angle.

AIM: To investigate the regulatory effects of nuclear factor-κB ( NF-κB) and activator protein-1 (AP-1) on the expression of ectopic trypsin and proinflammatory cytokines in influenza A virus (IAV)-induced myocardi-tis.METHODS:Male BALB/c mice of 8 weeks old ( n=40) were randomly divided into 4 groups:normal control group ( NC) , infection control group ( IC) , NF-κB inhibitor group ( NI) and AP-1 inhibitor group ( AI) .The mice in NC group and IC group were instilled intranasally with 15μL saline and 40 plaque forming units ( PFU) IAV, respectively.The mice in NI group and AI group were infected intranasally with 40 PFU IAV and injected intraperitoneally with 10 mg/kg NF-κB inhibitor pyrrolidine dithiocarbamate ( PDTC) or 2.5 mg/kg AP-1 inhibitor nordihydroguaiaretic acid ( NDGA) once daily. The mice were euthanized at day 9 after instillation, and the hearts were removed for pathological and biochemical analysis. RESULTS:IAV infection induced significant up-regulation of ectopic trypsin, and proinflammatory cytokines interleukin 6 (IL-6), IL-1βand tumor necrosis factor-α(TNF-α) in the myocardium, and triggered acute myocarditis.PDTC signifi-cantly inhibited NF-κB activation and up-regulation of ectopic trypsin and proinflammatory cytokines, and effectively sup-pressed IAV replication and myocardial inflammatory response (P<0.01).NDGA effectively inhibited AP-1 activity (P<0.01) and mildly suppressed up-regulation of proinflammatory cytokines ( P<0.05) , but had no effects on the expression of ectopic trypsin, IAV replication and the extent of myocarditis ( P>0.05) .CONCLUSION:IAV infection induces up-regulation of ectopic trypsin and proinflammatory cytokines in myocardium predominantly by the activation of NF-κB.AP-1 signaling pathway might be only partially involved in the regulation of proinflammatory cytokines.

Objective To evaluate the killing effects of cytosine deaminase (CD) gene mediated by adeno virus vector on human pancreatic cancer cell lines in vitro. Methods After CD gene was cloned into pAdTrack CMV CD, pAdTrack CMV CD and pAdEasy 1 were recombinated in bacteria. The newly recombinated Ad CD containing green fluorescent protein (GFP) was propagated in 293 cells and purified by cesium chloride gradient centrifugation. Human pancreatic cancer cell lines Patu 8988 and SW 1990 were infected with this virus, then 5 FC was added, XTT assay was used to estimate relative numbers of viable cell. Results The positive clones were selected by using endonuclease to digest the combinatants and the concentration of viral liquids containing CD gene was 2?10 11 PFU/ml. It was found that significant cytotoxic activities were possessed by 5 FC for CD gene transduced pancreatic cell lines, but little effects on the nontransduced pancreatic carcinoma cells. Conclusions CD gene mediated by adenovirus has a high infectivity and is efficient for gene therapy of pancreatic carcinoma cell lines. These data demonstrate the therapeutic efficacy of an enzyme as a prodrug strategy in experimental pancreatic cancer.

CG. And that was why SSP failed to determine the allele.Conclusion The difficulty in HLA genotyping by SSP resulted from the primers, which involved unknown sequence of Exon 1 at locus B in the studied sample.

Objective To investigate the DNA methylation feature and DNA methylation regulation to its transcription and expression of O6-methylguanine-DNA methyltransferase gene (MGMT) in NaAsO2-treated HaCaT cells. Methods HaCaT cells were treated 72 hours at intervals and repeatedly by 3.13, 6.25,12.50, and 25.00 μmol/L NaAsO2, MGMT gene promoter region was amplified in the transcription initiation site - 329 - + 93 region by bisulfate-sequencing polymerase chain reaction (BSP), the mRNA transcription and the protein expression of MGMT was detected by real-time quantitative PCR and Western blotting. NaAsO2-untreated HaCaT cell was set as a blank control, and human epidermal squamous carcinoma cell strain A431 was set as a positive control. Results Among the groups of HaCaT cells treated with 3.13, 6.25, 12.50 and 25.00 μmol/L NaAsO2, the positive rates of the DNA methylation of promoter region in MGMT gene were 0.63%(l/160), 6.25% (10/160), 10.63%( 17/160) and 18.75% (30/160), respectively, and methylated CpG sites were mainly located in - 249--146 region relative to transcription start site. There was no DNA methylation in the blank control. There were significant differences between the blank control and the NaAsO2-treated cells (x2 = 76.687, P< 0.05). Average levels of MGMT mRNA were 1.518 31 ± 0.180 54, 1.425 22 ± 0.180 39, 1.014 54 ± 0.096 79 and 0.887 72 ± 0.020 00, respectively among the groups of HaCaT cells treated with 3.13, 6.25, 12.50 and 25.00 μmol/L NaAsO2, compared with the blank control cells(1.198 29 ± 0.159 97), there were significant differences(F = 37.359, P < 0.05). Average levels of MGMT protein were 1.174 47 ± 0.064 75, 0.848 83 ± 0.057 01, 0.471 63 ± 0.023 34 and 0.240 34 ± 0.014 43, respectively among the groups of HaCaT cells treated with 3.13, 6.25, 12.50 and 25.00 μmol/L NaAsO2, compared with the blank control cells (1.066 19 ± 0.061 24), there were significant differences(F = 20.687, P < 0.05). Conclusions Arsenic can cause CpC island hypermethylation in the promoter region of MGMT gene, which results in inhibited MGMT mRNA transcription and protein expression. It might be one of the important mechanisms of arsenic-induced skin lesion.

To investigate the expression of the HO-1 gene in PC12 cells in hypoxic environment and gain further insight to the role of HO-1 in cerebral ischemia, PC12 cells were exposed to hypoxia environment (95% N2, 5% CO2) for 0.5 h, 1 h, 4 h, 8 h, 12 h, 24 h respectively. The level of HO-1 mRNA was examined by reverse transcriptase polymerase chain reaction (RT-PCR); the volume of COHb in the media were measured spectrophotometrically and the cGMP concentration of PC12 cell extracts was determined by radioimmunoassay. We found that after exposure to hypoxia for 1 h, 4 h, 8 h, 12 h, 24 h, HO-1 mRNA increased by 3%, 4%, 17%, 31% 36% as compared with that in control group respectively (P < 0.01 or P < 0.05); the COHb increased by 12%, 29%, 59%, 88%, 94% as compared with that in control group respectively (P < 0.01 or P < 0.05), and the cGMP concentration were 2.2, 3.4, 5.2, 8.1, 10.9-fold as that of the control group (P < 0.01). We are led to conclude that hypoxia induced the expression of HO-1 gene, the production of endogenous CO, and the concentration of cGMP was elevated as well.
