? 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.

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 evaluate the efficacy of the flexible ureteroscopy and Holmium and FREDDY laser lithotripsy for renal calculi at various locations.Methods From May 2002 to May 2007,338 cases of renal calculi(sized less than 20 mm in diameter)were treated by flexible ureteroscopy and laser lithotripsy in our hospital.The data of the patients were analyzed retrospectively.Among the cases,the calculi were located at the upper or middle calyx or the renal pelvis in 288 patients,at the lower calyx in 37,and in multiple calyxes in 13.All the patients received KUB and IVU before the procedures.With the TerumoTM settled in place,a F8/9.8 Wolf rigid ureteroscope was inserted to observe and dilate the ureteral lumen.Then,an Olympus P3 6.9F flexible ureteroscope was used.When the insertion of the rigid ureteroscope was difficult,a re-ureteroscopy would be tried 2 weeks later with a pig-tail stent in place.The WOM U-100 FREDDY laser and the Lumenis Holmium laser were used to perform the procedure and a pig-tail stent would be set at the end of the procedure.The urethral catheter was removed in the first postoperative day and an intravenous antibiotic prophylaxis was administrated during the first 2 days postoperatively.A follow-up by KUB or non-contrast CT scan was done 4 weeks after the procedure to evaluate the result of the endoscopic nephrolithotripsy.Any residual calculi larger than 4 mm in diameter was taken significant.Results In 28 patients the rigid ureteroscope or the ureteral sheath couldn't be inserted in the first time,and the success rate of the ureteroscopic insertion was 91.7%(310/338).The re-ureteroscopy was successful in the patients after 2 weeks.The calculi were detected in 97.3%(329/338)of the patients,and the procedures succeeded in 306 of them(306/329,93.0%).The success rate of laser nephrolithotomy was 78.0%(32/41)for the lower calyx calculi,which was significantly lower than that for the middle,upper calyxes or renal pelvic calculi 95.1%(274/288),?2=13.601,P=0.000].After 4 weeks,the total evacuation rate of the calculi was 87.6%(296/338).For the calculi in the upper or middle pole or in the renal pelvis,the complete evacuation rate was 90.1%(264/293),which was significantly higher than that for the lower pole 71.1%(32/45),?2=12.929,P=0.000].No patient had ureteric perforation or active bleeding after the surgery.The mean operation time was 35 min(12-55 min).After the operation,11 cases developed nephritic colic.None of them had septicemia or acute renal failure.Gross hematuria disappeared in 1-2 days postperation.Conclusions The flexible ureteroscopy and Holmium and FREDDY laser lithotripsy are safe and effective for renal calculi sized less than 20 mm in diameter,especially for those in the upper,middle poles and renal pelvis.A re-ureteroscopy with the pig-tail stent in place is suggested in two weeks after the failure of the first procedure.

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.

Objective To perform comparative proteomic analysis of human ovarian cancer cell lines for detecting platinum-resistance associated proteins.Methods The total proteins of two sensitive (SKOV3 and A2780)and four resistant(SKOV3/CDDP,SKOV3/CBP,A2780/CDDP and A2780/CBP) human ovarian cancer cell lines were separated by two-dimensional gel electrophoresis(2-DE).The differentially expressed proteins were analyzed using image analysis software,stained with Coomassie Brilliant Blue,then identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS)and database searching.The mRNA and protein levels of the differentially expressed protein which was most significant in all of the four resistant cell lines were validated by RT-PCR and western blotting,respectively.Results Five proteins were found to be significant in four cell lines. Annexin A3 and destrin were up-regulated and nicotinamide-adenine dinucleotide phosphate(NADP)- dependent isocitrate dehydrogenase 1 was down-regulated in all the four resistant samples.Glutathione transferase omega 1 had an increased expression in the other three resistant cell lines except for SKOV3/CBP in which its expression was not changed.However,cofilin 1 represented a different trend.In the two resistant sublines of SKOV3,eofilin 1 had a down-regulation,but it had an up-regulation in the cell lines induced from SKOV3.The expression of annexin A3 was up-regulated by 3-20 fold and the results of RT- PCR and western blotting showed complete consistency with that by 2-DE.Conclusions Proteomic techniques are useful to the identification of the resistance-associated proteins in ovarian cancer platinum- resistant cell lines and five candidates have been found.The five differential proteins might become hopeful candidate biomarkers for resistance.

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.
