Pupillary exudative membrane could occur after cataract extraction and intraocular lens implantation. Tissue plasminogen activator (10?g) was injected into the anterior chamber for treatment of the membrane, and its effect and toxicity were investigated. The membrane was dissolved completely in 5 of 7 eases in a mean time of 1.3 hours (0.5-3 hours), and dissolved partially in 2 cases. After the injection, on the second day the membrane recurred in 2eases, and headache and periorbital pain occurred on the involved side in 2 cases. No corneal endothelial toxic reaction was seen.

Aspheric intraocular lenses(IOLs)have been shown to provide better quality of vision than spherical IOLs.However,these lenses are not ideal for all patients.Surgeons may have different strategies for compensating for the patients's cornea spherical aberration,targeting a postoperative spherical aberration of zero or +0.10 ?m.But we must know that the negative spherical aberration aspheric IOLs require very good centration with respect to the visual axis of the eye.

Recently more and more ophthalmologists selected a multifocal intraocular lens (IOL) for their cataract patient in order to get good unaided reading vision. Although the design of IOL have made a great progress, we are still dissatisfied compared with our natural crystal lens. Understanding the design theory and improving our surgery technique are basic for better utilization the multifocal IOL. Does the multifocal IOL reduce contrast sensitivity? Should we implant the multifocal IOL in pediatric cataract surgery? How can we deal with the residual refractive error after multifocal IOL implantation? In this editorial, we try to clarify these problems to make us select and use multifocal IOL better.

Cataract and age-related macular degeneration (AMD) often present concurrently in aged persons. There has been a longstanding controversy among clinicians as to whether cataract surgery is contraindicated in eyes with AMD. Most of previous researches indicated that cataract surgery could accelerate the progression of AMD. However recently studies suggested that cataract surgery improved visual function of the patients and didn't accelerate the progression of AMD. These are related to the development of cataract surgery and the using of phacoemulsification technique.

Thrombolysis is still an important treatment modality in patients with ST-segment elevation myocardial infarction (STEMI) in a hospital without percutaneous coronary intervention (PCI) facility. However, the optimal treatment after thrombolysis is still unclear. Conservative treatment after thrombolysis was recommended in the past. "Guidelines for percutaneous coronary intervention (2009)" also suggested that the condition of STEMI patients should be evaluated to determine whether the patient should be transferred to a hospital with PCI facility. But this suggestion lacksed evidence-based support. In recent years, several clinical trials suggested that immediate transfer to the nearest interventional centre for PCI was plausible regardless of success or failure in thrombolysis in local hospital, and this might reduce the incidence of cardiovascular events in patients with STEMI.

Objective To investigate the clinical efficacy and safety of transurthral electrovaporization of the prostate(TUVP) for benign prostatic hyperplasia( BPH) at high risk.Methods Forty-eight patients with BPH at high risk were treated with transurthral electrovaporization of the prostate(TUVP).The clinical data and therapeutic results were measured.Results All patients went through the perioperiative period safely and had been followed up for 3 to 14 months.Postvoid residual ( PVR) , the International Prostate Symptom Score (IPSS) and quality of life (QOL) before operations were (97.5 ± 16.9) ml, ( 28.4 ± 2.3 ) score and (5.5 ±0.6) score respectively.Three months after operation ,PVR ,IPSS and QOL were( 30.2 ± 12.3 ) ml, (8.2 ± 1.3 ) score and( 1.9 ±0.5) score respectively,there was significant difference between them(t =22.31,53.16,31.94,all P<0.05).Conclusion TUVP is an effective and safe method in treating BPH patients at high risk.

OBJECTIVE: To investigate the effect of enzymatically modified low density lipoprotein(E-LDL) on differation and maturation of human dendritic cells(DC) in peripheral blood and the effect of diltiazem on it.METHODS: Human monocytes were isolated by using gradient centrifugation method and cultured in DC Cellgro medium containing rhGM-CSF and rhIL-4 for 5 days,then DC was then obtained.DC were treated with E-LDL or E-LDL plus diltiazem for 48 hours,the morphological changes were observed under the microscope,and the FACS was used to investigate the expression of DC(CD1a,CD80,CD86 and HLA-DR).PBS group was set up for comparison.RESULTS: The morphological changes were nor observed.The expressions of CD1a,CD80,CD86 and HLA-DR in each groups were significant different(P

Objective To observe the alteration of Bcl-2 and Fas-L at various intervals after traumatic brain injury and study the relationship between the alteration and the post-injury interval. Method The rat brain contusion was incurred by falling impact injury, paraffin section was cut after the test group rats were killed after various survival interval and stained with antibody of Bcl-2 and Fas-L, the hemotoxylin and eosin (HE) staining was carried out meanwhile. The staining results were measured quantitatively with computer imaging analysis system. Results Positive staining nerve celis were observed around the contusion area. At 30min after injury, a few Bcl-2 could be found around the wound, the intensity and the quantity of Bcl-2 positive celis increased significantly as post-injury interval extended. At 4h, the intensity came to a peak. Then the staining decreased. Although some Fas-L positive staining celis could be found around the wound at 30min after injury, the staining increased insignificantly from Ih to 4h after the injury. After 4h, the Fas-L positive staining cell increased significantly both in intensity and in quantity as post-injury interval extended. Conclusion There is a rule that the expression of Bcl-2 and Fas-L alters along with post-injury interval extension, which will be of value in time estimation of brain injury.

1.5mm)and received CTR scleral fixation.Visual acuity before and after surgery were examined.IOL tilt and decentration were measured with PentaCam system.Complications were also recorded.Main Outcome Measures Postoperative visual improvement,IOL position and complications.Results At the last postoperative examination,best corrected visual acuities of all eyes were increased(P=0.000).The mean IOL tilt was 4.33?2.96?before and 4.11?2.05?after CTR fixation,the mean decentration was 2.56?0.90mm before and 1.19?0.71mm after.No significant differences were found in IOL tilt before and after CTR fixation(P=0.844),but there were significant differences in IOL decentration(P=0.009).Posterior capsular opacification was found in 8 eyes(20.5%)during the follow-up period,and 2 eyes(5.1%)received Nd:YAG posterior capsulotomy.1 eye received IOL scleral fixation because of capsule rupture during CTR implantation.2 eyes suffered from temporary IOP elevation after surgery.No other severe complications occurred.Conclusions Phacoemulsification with CTR and IOL implantation is effective and safe for congenital subluxated lenses.CTR scleral fixation is a necessary supplement for severely subluxated lenses and progressive cases.

Objective To evaluate the effect on the corneal endothelial cell after phacoemulsification using the microburst mode with high vacuum. Design Prospective,observational case series. Participants 98 age-related cataract patients (120 eyes). Metheds All patients having phacoemulsification with the Alcon Legacy 20000 Everest software were assigned to 1 of 3 groups (the burst mode group,the pulse mode group and the continuous mode group). Main Outcome Measures Actual power,effect phaco time,visual acuity,corneal edema,and corneal endothelial cell loss. Results The mean actual power of the burst group was statistically lower than those of the other two groups,the effect phaco time of the burst group was statistically shorter than those of the other two groups. The corneal edema and the endothelial cell loss of the burst group were less than those of the other two groups. Conclusion The microburst mode with high vacuum increased efficiency of ultrasound power and decreased the loss of endothelial cell. (Ophthalmol CHN,2006,15: 201-205)
