AIM: To observe the therapeutic effect and safety of improved extra panretinal photocoagulation ( E - PRP) in the treatment of high risk proliferative diabetic retinopathy (hsPDR).
METHODS: A total of 88 consecutive cases (102 eyes) with hsPDR were diagnosed by fundus fluorescein angiography(FFA) from February 2011 to December 2014 in our hospital . Fifty two eyes had been treated by improved E - PRP with 532nm frequency - doubled laser. Fifty eyes had been treated by standard PRP. All cases were checked by FFA and fundus photocoagulation every 3mo. Patients with persisting neovascularization or non perfusion area were treated with laser again. All cases were followed up 6-36mo.
RESULTS: The postoperative visual acuity had no statistical difference between two groups ( P > 0. 05). In improved E - PRP group, retinal non perfusion area and neovascularization disappeared in 35 eyes ( 67%). Effective rate was 88%. Six eyes (12%) underwent pars plana vitrectomy because of vitreous hemorrhage, fiberosis and stretched retinal detachment. In standard PRP group, retinal nonperfusion area and neovascularization disappeared in 23 eyes ( 46%). Effective rate was 66%. Seventeen eyes(34%) underwent pars plana vitrectomy because of anterior retina bleeding or vitreous hemorrhage. The rate of neovascularization disappeared and effective rate had statistical difference between two groups (P<0. 05).
CONCLUSION: It is a safe and effective methods to treat hsPDR by improved E-PRP and it was more effective than traditional PRP.

Objective:To evaluate the security, efficacy and side effects of E_2 transdermal patch (Fem-7) in the treatment of menopausal syndrome. Methods:A total of 60 cases with menopausal syndrome (blood serum FSH >30 U/L,E_2 <109.8 pmol/L) were randomly divided into treatment group ( Fem-7 group) and control group (estrodiol valerate (E_2V) group) for 12 weeks treatment. Fem-7 group changed patch every 7 days and took the 2 mg medroxyprogesterone (MPA) every day. While the E_2V group took the 2 mg MPA and 1.5 mg E_2 V every day. Serum E_2, FSH, lipoprotein and coagulation function were evaluated at baseline and at the 12th week of the treatment. In addition, menopausal symptoms and some other index of security and side effects were also observed. Results:Kupperman indix in both groups was decreased and the mean value of E_2 was increased obviously. Hepatic function, renal function, coagulation function and blood glucose were no obvious change. Lipoproteina was descended markedly in Fem-7 group. Other index of security in both groups was no obvious change. Conclusions:Fem-7 patch is secure and valid for relieving symptom of menopause, especially for the women who is not sutable for oral medication.

Objective To explore the expression of 10 kDa interferon-gamma-induced protein(IP-10)in pathological scar and its role in the pathogenesis of pathological scar.Methods Imrnunohistochemistry was performed to detect the expression and distribution of IP-10 in 28 patients with keloid(group K),34 patients with hypertrophic scar(group HS),and 20 normal controls(group N).The data were collected and analyzed statistically.Results The expression of IP-10 was significantly higher in groups K and HS than in group N(P＜0.01),but no significant difference in the expression of IP-10 was found between groups K and HS.Conclusion IP-10 may enhance the formation of pathological scar by attracting T lymphocytes and inducing immune/inflammatory response.

Objective To study a improved technique by releasing the orbicularis retaining ligament in orbicularis oculi muscle supension blepharoplasty. Release of the orbicularis retaining ligament could cut off the contact between orbitomalar skin and periosteum at inferior orbital rim, and carry the point of tightening orbitomalar skin in orbicularis oculi muscle supension blepharoplasty. Methods There were 409 patients with apparent orbitmalar fold. The methods of releasing orbicularis retaining ligament and orbital septum fixation were added to improve the orbicularis oculi muscle supension blepharoplasty. Results 409 cases were treated using this method over the past 3 years. All results were satisfactory. No complications were observed. Conclusion This improved method of orbicularis oculi muscle supension blepharoplasty is useful for orbitomalar skin rolling, especially for orbitmalar fold. The release allows effective redraping and upward mobilization of the orbicularis of the lower lid and the premalar soft tissues. This method is a simple, safe and effective procedure for the correction of tear trough deformity and well-demarcated lid/cheek junction in lower eyelid belpharoplasty. It is one of the best choices for lower eyelid blepharoplasty.

Epiretinal membrane (ERM) is a relatively common macular disease that forms along the surface of the internal limiting membrane (ILM) of the retina to some reason.The pathogenesis is not clear.Microincision vitrectomy surgery has been confirmed as a minimally invasive and very safe modality of treatment.Deciding when to perform a vitrectomy can be difficult.There are many factors which can affect the postoperative visual acuity,such as age,the thickness of macular,integrity of photoreceptor inner segment/outer segment (IS/OS) junction.

Background Treatment of corneal ulceration by transplanting drug-loaded amniotic membrane has been used widespreadly abroad,however,seldom study is found in China up to now.Objective This study was to explore the sustained release property and the efficacy of the drug-loaded amniotic membrane.Methods The bacteriostatic area of amniotic membrane fragments immersed with different concentrations (5,20,30 g/L) of levofloxacin for different time points (5,15,30,60 minutes) was evaluated by in vitro test.Bacterial corneal ulceration models were established in 20 rabbits by injected 0.7 MCF staphylococcus aureus suspension (0.1 ml) into the central corneal stroma to form the cloudy area of 4.0-6.0 mm.Then the rabbits were randomized into two groups.Regular amniotic membrane transplantation was performed laterally and 0.5％ levofloxacin drops was topically administered after operation in the amnion+levofloxacin drops group,and drug-loading amnion transplantation was used in the drug-loading amnion group.Aqueous humor of 0.1 ml was collected in 30 minutes,1 hour,2,3.5,5.5 hours after levofloxacin was administered and 1 day,3,7,10,14,21 days after operation for the detect of levofloxacin level with high-performance liquid chromatography.The corneal symptom was scored based on McNeill's criteria in 1 week,2 weeks and 4 weeks and the ulceration area was assessed under the slit lamp in the first week.The pathological examination was carried out in the fourth week after surgery.Results The mean bacteriostatic area was bigger with the increase of levofloxacin concentration,and bacteriostatic area in amnion immersed for 15 minutes was bigger than that of 5 minutes (P＜0.01).The levofloxacin concentration of aqueous humor after transplantation was decreased by extending the time,and that in 30 minutes and 5.5 hours after operation was (0.873±0.264) mg/L and (0.106±0.027) mg/L,respectively,in the amnion+levofloxacin drops group,and that in day 1,3,7 after surgery in the drug-loading amnion group was higher than at 30 minutes in the amnion+levofloxacin drops group,showing all significant differences (all P =0.00).In the first,second and fourth week after operation,the corneal symptom score was 1.7±0.6,1.3±0.5,0.2±0.4 in the drug-loading amnion group and 2.2±0.8,2.0±0.6,1.5±0.8 in the amnion+ levofloxacin drops group,with the significant differences among the different groups and time points (Fgroup =9.49,P =0.01 ;Ftime =22.96,P=0.01).The corneal ulceration area was (1.6±0.6) mm2 in the drug-loading amnion group and (3.2±0.8) mm2 in the amnion+levofloxacin drops group 1 week after operation,showing a significant difference between them (t =3.98,P =0.00).Histopathological revealed that the various layers of cornea tissue appeared irregular arrangement in the amnion + levofloxacin drops group 4 weeks after operation with 1-2 layers of new squamous epithelium.Disorder hypothallus structure,more inflammatory cells and residual vascular cavity were visible.However,new squamous epithelium of 4-5 layers was seen in the drug-loading amnion group,and inflammatory cells and residual vascular cavity were less than the amnion+levofloxacin drops group 4 weeks after operation.Conclusions Levofloxacin-loaded amniotic membrane can sustained release levofloxacin and maintain an effective drug concentration in aqueous humor,which improves the treating efficacy for staphylococcus aureus corneal ulceration.
