Objective To investigate the efficacy and safety of intravitreal ranibizumab and (or) triamcinolone combined with laser photocoagulation for macular edema secondary to branch retinal vein occlusion (BRVO) during one year period.Methods The data of 31 eyes from 31 consecutive patients with macular edema secondary to BRVO during one year follow-up visit were retrospectively analyzed.Mean best corrected visual acuity (BCVA) logMAR was (0.74±0.36) and mean central retinal thickness (CRT) was (484.48± 164.81) μm at baseline.All patients received standardized clinical comprehensive examinations including vision,intraocular pressure and optical coherence tomography for diagnosis before treatment.All patients received intravitreal injections of 0.5 mg ranibizumab (0.05 ml) at first visit.The continue PRN treatment were based on the visual acuity changes and the optical coherence tomography findings.Eyes received combined triamcinolone acetonide 0.05 ml (40 mg/ml) and ranibizumab for macular edema recurrence after two injections of ranibizumab and received laser photocoagulation during 10-14 days after third injections of ranibizumab.Mean injection of ranibizumab was 3.52± 2.01,15 eyes with triamcinolone acetonide (0.84 ± 1.21),21 eyes with laser photocoagulation (0.97± 0.95) and 12 eyes with three treatment.Compared the visual acuities and CRTs of the first and the last visits by statistical analysis.Results Mean visual acuity improved significantly to 0.42±0.33 logMAR (t=6.611,P=0.000).Mean improvement of visual acuity was 2.90± 3.07 lines.A gain of three or more logarithmic lines was evaluated in 20/31 eyes (64.52％) at the last visit.Mean CRT was (326.19± 117.80) μm (t=4.514,P=0.000).Mean reduction of CRT was (333.58±134.17) μm.A decrease of 100 μm of CRT was evaluated in 17/31 eyes (54.84％).No severe ocular and systematic side effect was found.Conclusion The efficacy and safety of intravitreal ranibizumab and (or) triamcinolone combined with laser photocoagulation for macular edema secondary to BRVO were assured.

Corticosteroids,anti-vascular endothelial growth factor,antibiotics and antiviral were the main 4 classes of drugs for intravitreal injection.Depending on the class and volume of medication,age and gender of patients,ocular axial lengths or vitreous humour reflux,intraocular pressure (IOP) can be elevated transiently or persistently after intravitreal injection.Transient IOP elevation occurred in 2 weeks after intravitreal injection,and can be reduced to normal level for most patients.Only a small portion of such patients have very high IOP and need intervention measures such as anterior chamber puncture or lowering intraocular pressure by drugs.Long term IOP elevation is refers to persistent IOP increase after 2 weeks after intravitreal injection,and cause optic nerve irreversible damage and decline in the visual function of patients.Thus drug or surgical intervention need to be considered for those patients with high and long period of elevated IOP.Large-scale multicenter clinical trials need to be performed to evaluate the roles of the drug and patients factors for IOP of post-intravitreal injection,and to determine if it is necessary and how to use methods reducing IOP before intravitreal injection.

Objective To study the effect of selective COX-2 inhibitor NS-398 on IL-1α and TNF a expression in HaCaT cells induced by UVA/UVB,and further to explore the mechanism on anti human skin photo damage. Methods The subcuhured HaCaT cells were divided into three groups:simple illuminated group was exposed to UVA/UVB directly,NS-398 interfered group was exposed to UVA/UVB after being treated with NS-398 in different concentrations,and the control group was cultured in normal without any treatment.The expression of IL -1α and TNF-α in supernarant was detected by ELISA kit.Results The level of IL-1α and TNF-α expression in supernatant from simple illuminated group was remarkably higher than that in the control group,NS-398 interfered group showed much lower level than the simple illuminated one,and the expression of IL-1α and TNF-α was dependent on the concentration of NS-398.Conclusions NS-398 can reduce IL-1α and TNF-α expression in HaCaT cells induced by ultraviolet rays,suggesting the possibility of anti human skin photo- damage effect.

Objective Study on the spread and the development history of traditional Chinese medicine in Africa, as well as the present situation and trend, provide reference for better promoting China-Africa cooperation of traditional Chinese medicine. Methods Literature review and historical research methods are used to retrospect the process of traditional Chinese medicine into Africa, and analyze the typical event. Results traditional Chinese medicine was introduced into Africa's history dates back to the period of Zheng He's voyage. In 1963, China sent medical teams to Africa, the TCM comprehensive spread in Africa started. In 2005, China sent the first group of traditional Chinese medicine volunteers to Africa, which a new pattern of TCM spread. Conclusions By sending the medical teams, volunteers, and education training, academic conferences, traditional Chinese medicine was gradually known by the African people. TCM is developing rapidly by the supporting of the government. The opportunity should be seized to promote the comprehensive development of traditional Chinese medicine in Africa.

Objective To compare the effect of different ways of water supply and whether or not drain water from waterlines for overnight on bacterial counts in dental unit waterlines(DUWLs).Methods In the first phase,6 sets of DUWLs were randomly divided into 2 groups (external storage tank water supply group and municipal water sup-ply group);in the second phase,6 sets of DUWLs were all changed to use external storage tank and randomly di-vided into 2 groups (draining water for overnight group and without draining water for overnight group),bacterial count before and within one week of disinfection between two groups at two phases were compared respectively. Results In the first phase,handpiece water of DUWLs was most seriously contaminated by bacteria,the average colony count was 4117 CFU/mL,qualified rate was 15.38%.Before disinfection,no significant difference in bacte-rial count were found among each groups (all P>0.05),bacterial count of DUWLs of all groups severely exceeded the standard(all >3000 CFU/mL).Comparison of bacterial count in DUWLs from different water supply routes after disinfection was not significantly different on day 1(P>0.05),but were significantly different at day 2-7(all P<0.05).On the second day after disinfection,municipal water supply group began to exceed bacteria standard;on the third day after disinfection,external storage tank group began to exceed bacteria standard.Bacterial count in DUWLs after disinfection between draining water for overnight group and without draining water for overnight group was no significantly different on day 1(P>0.05),but were significantly different on day 2-7(all P<0.05). On the fourth day of disinfection,bacterial count of without draining water for overnight group exceeded standard.On day 7 of disinfection,bacterial count in draining water for overnight group exceeded>100 CFU/mL.Conclusion Use of external storage tank,daily change of sterile distilled water,and daily emptying water for overnight can effectively reduce bacterial count in DUWLs.

Objective To investigate the factors associated with vision and hole closure for idiopathic macular hole (IMH) after vitrectomy surgery.Methods Eighty-nine eyes of 89 patients with IMH were enrolled in this retrospective study.There were 15 males and 74 females.The patients aged from 42 to 82 years,with the mean age of (64.13 ± 7.20) years.All subjects underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examinations.The BCVA ranged from 0.01 to 0.4,with the mean BCVA of 0.12 ± 0.09.The MH stages was ranged from 2 to 4,with the mean stages of 3.56 ± 0.77.The basal diameter ranged from 182 μm to 1569 μm,with the mean basal diameter of (782.52± 339.17) μm.The treatment was conventional 25G pars plana vitrectomy combined with phacoemulsification and intraocular implantation.Fortyone eyes received internal limiting membrane peeling and 48 eyes received internal limiting membrane grafting.The follow-up ranged from 28 to 720 days,with the mean follow-up of (153.73 ± 160.95) days.The visual acuity and hole closure were evaluated on the last visit and the possible related factors were analyzed.Results On the last visit,the BCVA ranged from 0.02 to 0.8,with the mean BCVA of 0.26±0.18.Among 89 eyes,vision improved in 45 eyes (50.56％) and stabled in 44 eyes (49.44％).Eighty-six eyes (96.63％) gained MH closure but 3 eyes (3.37％) failed.By analysis,patients of early stages of MH and smaller basal diameter of MH will gain better vision outcome (t=2.092,2.569;P＜ 0.05) and patients of early stage MH will gain high hole closure rate after surgery for IMH (t=-5.413,P＜0.05).However,gender,age,duration,preoperative BCVA,surgery technique,gas types and follow-up time had no relationship with the effect after surgery for IMH (P＞0.05).Conclusions Stages of MH and basal diameter of MH may be the factors associated with the visual outcome for idiopathic macular hole after surgery.However,age,gender,duration,surgery patterns,gas types and followup time showed no effects on operational outcomes.
