ObjectiveTo observe the retinal function and nerve fiber layer (RNFL) thickness after laser in situ keratomileusis (LASIK). MethodsLASIK was performed in 15 cases (30 eyes) with myopia after strict preoperative examination. All examinations such as vision, correction vision, diopter, intraocular pressure, corneal thickness, ocular axis, topography scan and fundus of eye examination were performed before and 1 day, 1 week, 1 month,3 months and 6 months after operation, as well as electroretinography (ERG), visual evoked potential (VEP), optical coherece tomography at same time. ResultsThere was not significant difference in the intraocular pressure, ERG and VEP 1 day after LASIK. The thickness of RNFL decreased 1 week after LASIK (P<0.05) and recovered 1～6 months later. ConclusionLASIK does not disturb the retinal function and RNFL thickness irreversiblely.

ObjectiveTo investigate the effect of filtering surgery on glaucoma.Methods50 glaucoma cases (60 eyes) were underwent trabeculectomy, including paracentesis in advance, suturing of sclera flap and conjunctiva flap, using mitomycin (MMC) and forming anterior chamber as soon as finished operation. All cases were followed up 1 year.ResultsPostoperative IOP was lower than 21 mmHg in 54 eyes, 6 eyes were <30 mmHg when treated with drugs. After operation, there were only 2 eyes had lower vision, the others had higher vision. Two eyes had conjunctiva filtering, two eyes had choroidal separation, but they recovered after non surgical therapy.ConclusionFiltering surgery can decrease common complications, increase vision of early stage, and make IOP recovered to normal.

In this paper, the process performance indexes (PPIs) P(p) and P(pk) were introduced and applied to evaluate the process capability and quality consistence of Chinese medicine products. The historical quality analysis data of Qingkailing injection were collected and taken as the research object. The confidence intervals of P(p) and P(pk) were estimated based on the Bootstrap sampling methods. Results showed that the value and width of the confidence interval P(p) of were smaller that of P(pk) suggesting that the P(pk) index was more sensitive than P(p) in process capability analysis. Within the production period concerned, the P(pk) values estimated from different quality indexes of Qingkailing injection, such as baicalin, cholic acid, geniposide and total nitrogen, were 1.122, 2.055, 1.564 and 0.891, respectively. It could be found that the cholic acid had the highest process capability, followed by the geniposide and baicalin. The total nitrogen had the lowest process capability, indicating that it is necessary to reinforce the quality management of total nitrogen related manufacturing processes. The case studies demonstrate the effectiveness and feasibility of PPIs, which are convenient to be used in production practice of Chinese medicine.

Results Compared with the control,the proliferating ability of EPCs exposed to PEMFs was stronger;the number ofⅧ-related antigen and NOS_3 positive cells increased significantly in EPCs exposed in PEMFs.Conclusion PEMFs promotes the proliferation and differentiation of rat bone marrow EPCs.

Background Oxidative stress is thought to be responsible to diabetes-complicated cataract.Our previous study demonstrated that as an iron chelator,deferiprone can protect lens from oxidative damage.Objective This further study aimed to investigate the role of deferiprone on the formation of diabetic-complicated cataract.Methods Forty 6-week-old Wistar rats were included in the study and randomized into 4 groups.Eight of them were used as the normal control group.Diabetes mellitus animal models were established in 22 rats by the carbonhydratediet and fat diet and the intraperitoneal injection of 40 mg/kg streptozocin (STZ).The deferiprone of 50 mg and 100 mg were intragastrically given in 8 model rats respectively after 3 days once a day for 8 weeks.The opacification of lenses was examined under the slit lamp weekly after treatment.The animals were sacrificed and the lenses were obtained at the eighth week of deferiprone injection.The concentrations of water-soluble protein ( WSP),urine-soluble protein (USP) and alkali-soluble protein (ASP) in rat lens suspension were detected by Bradford method.The super oxide dimutese (SOD),malondialdehyde (MDA) and glutathione (GSH) were determined spectrometically using xanthine oxidase,thiobarbituric acid,dithio bis-nitrobenzoic acid.Results No evidently differences were found in the content of the WSP,USP and ASP among the these groups( F=1.73,0.18,0.09,P＞0.05).The contents of MDA in 50 mg deferiprone group and 100 mg deferiprone group were ( 1.05 ± 0.10 ) mmol/g and ( 1.05 ± 0.22 ) mmol/g respectively,showing a significant decline in comparison with diabetic model group (P＜0.05).The SOD and GSH contents in lens were (321.29±16.57) U/mg,(322.07±22.16) U/mg and (7.83±0.65 ) mg/g,(7.70±0.77 ) mg/g respectively in 50 mg deferiprone group and 100 mg deferiprone group and were considerably elevated in comparison with ( 298.70± 14.69 ) U/mg and ( 5.47 ± 1.01 ) mg/g of diabetic model groups ( P＜0.05 ).No significant differences were found in the indexes mentioned above between 50 mg and 100 mg deferiprone groups(P＞0.05).Conclusions Deferiprone can reduce oxidative stress and improve the energy metabolism of the lens in diabetic rats.

· AIM: To study the in situ relative intraocular position of the iris-claw phakic intraocular lens (PIOL)for high myopia using an anterior chamber optical coherence tomography (AC OCT)prototype.· METHODS: Six PIOLs (11.50 to 22.00D lens powers) were implanted in phakic myopic eyes. Using AC OCT, tomography was taken in the anterior chamber to measure the preoperative anterior chamber depth, postoperative distance between the PIOL and the corneal endothelium (endothelial-optic distance), and the postoperative distance between the PIOL and the crystalline lens.· RESULTS: Preoperative anterior chamber depth ranged from 3.27 to 3.91 mm and the postoperative endothelial-optic distance measured 2,07 to 2,24 mm. The distance between the crystalline lens and the posterior surface of the IOL ranged from 0.82 to 1.32 mm. Several tomography revealed the position of the PIOL on the iris, The pigment layer of the iris did not seem to be disturbed by the presence of the PIOL.· CONCLUSION, The original anterior chamber depths were reduced by 36,1% to 44.6% after implantation. This study of 6 eyes revealed that tomography taken by AC OCT are useful in verifying the intraocular position of the PIOL within the anterior chamber. Adequate space was maintained between the iris-fixated phakic intraocular lens and the corneal endothelium, angle, and crystalline lens.

Objective To observe the perioperative management of cardiac surgery and extracorporeal circulation method in patients with glucose-6-phosphate dehydrogenase deficiency(G6PD).Methods Ten patients with G6PD deficiency underwent uneventful cardiac surgery procedures between January 2005 and December 2010.Twenty patients who had non-G6PD deficiency were as a control group,the selected conditions were the same gender,age,body mass,the risk of heart disease surgery.The preoperative management in patients with G6PD deficiency mainly focused on avoiding the drugs implicated in haemolysis,reducing the surgical stress,using moderate hypothermia extracorporeal circulation and enhancing blood conservation.Observed indicators included the assisted ventilation time,urine volume,the drainage volume of chest tube,the amount transfusion of red blood cells and plasma,the level of hemoglobin and serum total bilirubin in the 2nd day after surgery,ICU stay.Results Compared with the control group,patients with G6PD deficiency had no significant difference in duration of ventilation after the operation,drainage,urine,Hgb,bilirubin levels,and blood transfusion[(9.3 ± 4.5)h vs (8.6 ± 5.7)h,(2100 ±670)ml vs (1950 ± 490) ml,(253 ± 146)ml vs (260 ± 120)ml,(1.3 ± 1.0)U vs (1.8 ± 1.2)U,(96 ± 25)g/L vs (99 ± 12)g/L,and (24 ± 8)μmol/L vs (27 ± 1 l)μmol/L,t =0.978,2.032,1.257,0.891,2.182,2.271,and 1.329,all P ＞ 0.05].The duration of ICU discharge was significantly longer in the glucose-6-phosphate dehydrogenase deficient group[ (2.6 ± 0.6)d vs (1.8 ± 1.5)d,t =2.704,P ＜ 0.05].Conclusions Cardiac surgery can be performed safely in patients with G6PD deficiency with enhanced perioperative management.

Objective To explore the effect of aminolevulinic acid-based photodynamic therapy(ALA-PDT) on alloreactived peripheral blood mononuclear cells(PBMCs).Methods Human PBMCs from different healthy donor were collected and mixed in the one-way mixed lymphocyte culture(MLC) for 5 days. The cells were harvested and aminolevulinic acid(ALA) were added into ALA group and ALA+Light group with ultimate concentrations of 0.5 mmol/L,1.0 mmol/L,1.5 mmol/L,2.0 mmol/L and 2.5 mmol/L.After cultured for 2 hours, 4 hours and 6 hours respectively in 37 ℃ 5% carbon dioxide incubator,Light group and ALA+Light group were irradiated by light of 410 nm wavelength for 1 hour.The MLC cells were treated with the former stimulator cells for 48 hours.The survival of stimulator cells were detected using MTT colorimetric assay and the kill rates of treated cells were calculated.Results The kill rate of ALA+Light group on stimulators was apparently lower than those of Light group, ALA group and control group, (33.0?26.5)% vs (87.1?2.2)%,(89.2?2.5)%,(90.3?1.9)%(All P
