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.

Strain QJ16,one of some methanotrophic bacteria isolated from soil samples utilizing the separate device designed by our laboratory;was studied in detail and identified as one of the Genus methylomonas through 16S rDNA sequencing and comparison. The culturing and reaction conditions for methane utilization of this strain were investigated. The results indicated that the optimal conditions for the growth of strain QJ16 were methane gas as carbon source and the coexistence of NH4Cl and KNO3 as nitrogen source,the cultivation temperature of 30℃ and medium initial pH 6～7,and the optimal Cu2+ concentration of 15 ?mol/L.

Chronic prostatitis is a common male disease, and its pathogenesis is not yet clear. Most scholars believe that oxidative stress and immune imbalance are the keys to the occurrence and progression of chronic prostatitis. Currently immunotherapy of chronic prostatitis remains in the exploratory stage. This article relates the active ingredients of 5 Chinese medicinal herbs (total glucosides of paeony, tripterigium wilfordii polglycosidium, curcumin, geniposide, and quercetin) for the treatment of chronic prostatitis and their possible action mechanisms as follows: 1) inhibiting the immune response and activation and proliferation of T-cells, and adjusting the proportion of Th1/Th2 cells; 2) upregulating the expression of Treg and enhancing the patient's tolerability; 3) suppressing the activation of the NF-kB factor, reducing the release of iNOS, and further decreasing the release of NO, IL-2 and other inflammatory cytokines, which contribute to the suppression of the immune response; 4) inhibiting the production of such chemokines as MCP-1 and MIP-1α in order to reduce their induction of inflammatory response. Studies on the immune mechanisms of Chinese medicinal herbs in the treatment of chronic prostatitis are clinically valuable for the development of new drugs for this disease.

Objective To investigate clinicopathologic characteristics of obsolete Bennett fractures and their surgical treatment and prognosis. Methods From August 2008 to April 2010,13 patients with obsolete Bennett fracture were admitted to our department.They were 12 men and one woman,with an average age of 34.3 years (from 17 to 42 years).They had a fracture history of over 4 weeks to as long as 12 weeks (average,7.9 weeks).In all patients,after X-ray examinations,the radio-dorsal ligament complex of the first carpometacarpal joint was properly released,fracture gaps were cleared up,fracture fragments were anatomically reduced and fixed with a Kirschner wire,and at last the first metacarpal joint was fixed with the Kirschner wire crossing the joint Postoperatively all patients were immobilized with cast plaster for 4 weeks before the Kirschner wires acrross the joint were removed.Gradual rehabilitation was conducted.The X-rays were taken every month. Results The patients were followed for 6 to 24 months(average,14 months).The fractures healed in all the patients,with an average healing time of 3 months.No dislocation of the joints occurred.Injury to articular cartilage of the trapezium bone occurred in one patient,and no apparent pain was experienced in the other 12 patients.According to the Total Active Motion assessment,the thumb function was rated as excellent in 9 cases,good in 2,moderate in one and poor in one,with a good to excellent rate of 84.6％.Conclusions In obsolete Bennett fractures,the radio-dorsal ligament complex of the first carpometacarpal joint will have cicatricial contracture,preventing reduction of the fragments of the radio-dorsal joint.Therefore it is important to properly release the radio-dorsal ligament complex to achieve anatomical reduction of the radio-dorsal joint.An injury history of over 3 months and complicated injury to the trapezium bone cartilage may be significant factors affecting the prognosis of obsolete Bennett factures.

?AlM: To study the correlation between monocular mild myopic juvenile myopia degree and dominant eye.
? METHODS: Totally 158 patients with juvenile monocularly mild myopia in our hospital from December 2012 to December 2013 were retrospectively analyzed, and cylindrical mirror astigmatism was used for spherical equivalent conversion. On the basis of the myopic degree, they were divided into three groups, 30 cases in group A (-0. 25~-0. 75D), 92 cases in B group (-1. 0~-2. 0D), 36 cases in group C (-2. 25 ~ -3. 0D). The card hole method was selected to measure dominant eye for subjectsat nearly 33cm and 5m. After glasses correction of ametropia, the far and near dominant eyes were received measurement again.
?RESULTS:The monocular mild myopia of dominant eye was compared with the non-dominant eye adjustment function, and there was no significant difference ( P>0. 05 ) . The dominant eye, non - dominant eye mean diopter and other correlations of eyes in the three groups were compared, and there was no significant difference (P>0. 05). The dominant eye of three groups at 5m was compared, and there was significant difference (P<0. 05). The dominant eye of three groups at 33cm was compared, and there was significant difference (P<0. 05). Dominant eye at different visual distance was compared, and there was significant difference (P<0. 05). Monocular uncorrected eye was compared with dominant eye mild afte myopia glassesr, and there was significant difference (P< 0. 05).
?CONCLUSlON: The formation of myopic anisometropia is related to the degree of clearly seeing objects, although glasses correction can improve the clarity and visual, but affect the choice of the dominant eye, because the myopic anisometropia appears most early in the dominant eye, therefore optician correction stage, which should be taken into consideration, and avoid the severity of the adolescent myopia.

AIM: To observe the effect of intravenous methylprednisolone combined with peri - orbital injection of triamcinolone acetonide for diffuse - type orbital inflammatory pseudotumor.
METHODS: Diffuse - type orbital inflammatory pseudotumor in 15 cases ( 19 eyes ) were treated. Intravenous implosive methylprednisolone therapy (0. 5g/ d) was used in the first 3d, and 0. 5g once a week in the following 3wk, ended by 0. 25g once a week in the last 6wk, which meant the total dose was 4. 5g and the whole course lasted for 10wk. At the same time, peri - orbital injection of triamcinolone acetonide ( 40mg ) was performed once in every 3wk, totally 2-4 times.
RESULTS: Eight eyes from 7 cases were completely cured, 11 eyes from 8 cases were partly cured. No recurrence and severe complications were observed in the treatment duration.
CONCLUSION: Intravenous methylprednisolone combined with peri - orbital injection of triamcinolone acetonide is effective, safe and feasible in treatment of diffuse type orbital pseudotumor with less complications.
