Background Excimer laser corneal refractive surgery is widely used because it reduces the dependency of refractive error eye to glasses.However,the adverse effects of anti-inflammatory drugs is a problem after operation.Lotemax eyedrops is a kind of steroidal anti-inflammatory drug,with a good effect on the operative eye.But its influence on intraocular pressure(IOP) after long-term topical administration is less studied.Objective This study was to investigate the influence of lotemax eyedrops on IOP after long-term topical administration in myopic eyes received excimer laser corneal refractive surgery.Methods An one-month retrospective case serial study was adopted.The case history data of 1552 eyes from 1552 Patients who received excimer laser corneal refractive surgery were collected in Tangshan Eye Hospital from 2011 January to 2012 January,including 321 eyes with laser in situ keratomileusis(LASIK),608 eyes with sub-Bowman keratomileusis (SBK) and 623 eyes with femtosecond laser for flap excimer laser in situ keratomileusis(FS-LASIK).Lotemax eyedrops was topically administered after operation 4 times per day initial and then decreased 1 time weekly for 1 month.IOP was measured in before,1 week,2 weeks,3 weeks,4 weeks after operation with non-contact tonometer.The increasing range of IOP was divided into <5 mmHg,5-15 mmHg and > 15 mmHg after operation.Optical head parameters were measured by Heidelberg retina tomography when IOP increasing after operation.Results Within 1 month,elevated IOP was found in 47 of 1552 eyes after administration of lotemax eyedrops,including 3.12% (10/321) in the LASIK group,3.29% (20/608) in the SBK group and 2.73% (17/623) in the FS-LASIK group,without significant difference among them(x2 =1.95,P>0.05).The IOP elevated 1 week after operation and remained normal after that till drug withdrawal in all eyes.There were no significant differences in the disk area (1.65 ±0.44) mm2 vs.(1.66 ±0.44) mm2,disk volume (0.40 ±0.09)mm3 vs.(0.39±0.08) mm3 and mean nerve fiber layer thickness (0.28 ± 0.08) mm vs.(0.29 ± 0.07) mm in IOP elevation duration compared with 1 month after IOP recovery(t =0.34,0.81,0.48,P>0.05).Conclusions Topical administration of 0.5% lotemax eyedrops after excimer laser corneal refractive surgery leads to reversible high IOP.It is very important to monitor the IOP during use of the drug.

AIM:Nitroxyl ( HNO) increases myofilament Ca 2+responsiveness relative to increases in intracel-lular Ca2+in cardiac muscle.In this study, we further investigated this effect of HNO on trabecular muscles from phospho-lamban knockout ( PLB-KO) and wide-type ( WT ) mice using a novel HNO donor , 1-nitrosocyclohexyl acetate ( NCA ) . METHODS:Trabecular muscles were dissected from the right ventricles of the rat hearts and mounted between a force transducer and a motor arm.The muscles were superfused with K-H solution (pH 7.4) at room temperature.Fura-2 was loaded into the trabecular muscles via electrophoresis .The length of the sarcomere was set to 2.2~2.3μm.During stead-y-state activations, the maximal Ca2+-activated force and Ca2+required for 50% activation were measured.RESULTS:The intracellular Ca 2+transients and force of the PLB-KO muscles at baseline were higher than those of the WT muscles and exhibited a negative force-frequency relationship (FFR).NCA (2.5μmol/L) increased systolic force in both PLB-KO group and WT group at any given [Ca2+]o.However, there was more dramatic increase in the force development due to moderate increases in the intracellular Ca 2+transients in the WT muscles when external Ca 2+increased from 1.5 to 4.5 mmol/L under NCA.NCA did not affect the negative FFR in PLB-KO muscle.Steady-state force-Ca2+relations obtained from skinned muscles were not different between the 2 groups, while NCA increased Ca2+responsiveness in skinned mus-cles from both PLB-KO and WT mice.CONCLUSION:HNO increases force development in both PLB-KO and WT mus-cles as a result of increases in myofilament Ca 2+responsiveness .The increased intracellular Ca 2+transients are accompa-nied by greater force development in WT mice , suggesting that HNO improves Ca 2+activation and establishes HNO as a positive inotropic agent with novel mechanisms .

Stereotactic radiotherapy (SRT), also known as stereotactic ablative radiotherapy (SABR), includes stereotactic radiosurgery and stereotactic body radiotherapy (SBRT). This technique has the characteristics of large single fractional dose, few fractions, high equivalent biological doses, and rapid fall off-target doses. It can be implemented by relatively special equipment such as Gamma knife, Cyberknife, Tomotherapy and Vero 4D RT system, etc. In many cases, SBRT technique is employed based on linear accelerators. SRT differs from conventional radiotherapy in terms of the plan design and plan evaluation. Consequently, it is necessary to discuss the differences and provide guidance for clinical application and research.

Objective To explore the metabolic characteristic of prostate cancer (PCa) in central gland with magnetic resonance (MR) spectroscopic, and evaluate the value of MRS in the differential diagnosis of benign prostatic hyperplasia nodus. Methods MR images were performed in 38 cases with prostate disease by 3.0T MR, 11 cases with PCa in central gland and 27 cases with benign prostatic hyperplasia nodus. All the cases were scanned by routine, then by the combined MRS. MRS findings were reviewed in 27 cases with benign prostatic hyperplasia (BPH) and 11 cases with PCa (3 in central gland origin, 8 with large tumor invading both peripheral zone and central gland). (Cho+Cr)/Cit ratios of PCa and BPH were retrospectively measured, (Cho+Cr)/Cit of PCa voxels were compared with that of BPH voxels. Results Significantly higher choline levels and lower citrate levels were observed in central gland of PCa compared with BPH. In the glandular BPH region, the amount of Cit was high; while in the stromal region, the Cit and Cho level was much lower. The average (Cho+Cre)/Cit values of PCa and BHP were 1.94±1.43 and 0. 83±0. 28 respectively, the difference in ratio between both was statistically significant (P<0. 01). Conclusions The combined use of MRI and MR spectroscopy is propitious for differentiating prostate cancer in central gland and benign prostatic hyperplasia nodus and for increasing the diagnostic accuracy of prostate cancer.
