Background Acanthamoeba keratitis is a sort of serious infectious eye disease with high causing-blindness rate.Acanthamoeba keratitis often is misdiagnosed as fungal keratitis or viral keratitis in the early stage.Because conventional clinical diagnosis methods show a low specificity and take a long time,timely treatment often is delayed.Conventional PCR does not apply well because the lesion sample is not enough to extract DNA.However,direct PCR can amplify 18S rRNA conserved sequence of acanthamoeba keratitis without the extraction of DNA.Objective This study was to discuss the feasibility for rapid diagnosis of acanthamoeba keratitis using direct PCR to amplify the gene 18S rRNA fragment.Methods Ten acanthamoeba strains were isolated from 10 eyes with acanthamoeba keratitis in Qingdao Eye Hospital.The sensitivity of the direct PCR assay was tested using different numbers of amoebas.The specificity of the assay was tested using DNA extracted from acanthamoeba,candida albicans,pseudomonas aeruginosa,herpes simplex virus-1 (HSV-1) and normal human corneal epithelial cell.Acanthamoeba keratitis models were established using infected method in clean 6-week-old female BALB/c mice.Corneal lesion samples were obtained 1 day,3,5,7,10,15 days after modeled.The effectivity and feasibility of the direct PCR assay for rapid diagnosis of acanthamoeba keratitis were evaluated and compared with culture method,corneal smear examination and real-time PCR.Results Direct PCR primers could only amplify DNA of acanthamoeba rather than other pathogens,and 10 stains of acanthamoeba were detected at least in each sample.During the development of acanthamoeba keratitis in the mice,the diagnosis positive rate of direct PCR was 80.0%,90.0%,80.0%,70.0%,70.0% and 50.0% in 1 day,3,5,7,10,15 days after modeled with the total positive rate 73.3%,which was higher than 31.7% of culture method,56.7% of corneal smear examination and 61.7% of realtime PCR,with a significant difference between the direct PCR and culture method (P =0.005),but no significant difference was seen in the total positive rate between the direct PCR and real-time PC R (P =0.172) or corneal smear examination (P =0.056).Conclusions The direct PCR assay is a simple,rapid,highly specific and sensitive method for the rapid diagnosis of acanthamoeba keratitis,especially for the limited lesion sample.

AIM:To investigate the serum antibody of aquaporin 4 ( AQP4 - Ab ) in positive expression rate and the significance in patients with neuritis.
●METHODS: A total of 98 cases ( 128 eyes ) of patients with optic neuritis were studied to detect the patient′s serum AQP4-Ab positive rate of antinuclear antibodies ( ANAs) from Jan. 2012 to Dec. 2015 in ophthalmology center of our hospital. According to the expression of AQP4 - Ab group, the best corrected visual acuity between the two groups, peripapillary nerve fiber layer thickness (pRNFL), the volume of the macula, macular RNFL ( mRNFL ) , macular core layer volume ( mlNL ) measurement were compared.
●RESULTS:Ninety-eight patients (128 eyes) with optic neuritis cases diagnosed through examination revealed AQP4-Ab positive in 22 patients ( 22%) , negative in 76 patients ( 78%) , ANAs positive in 21 patients ( 21%) , negative 77 patients ( 79%) . Optic neuritis patients with serum AQP4 - Ab positive rate and ANAs positive significant correlation ( r = 0. 707, P < 0. 05 ). After examination revealed AQP4-Ab patients and negative-positive patients with best corrected visual acuity difference was not statistically significance (P>0. 05). After inspection found pRNFL, macular volume measured value AQP4 - Ab positive patients were significantly less than the negative patients, the differences were statistically significant (P<0. 05). AQP4-Ab positive patients and negative patients the mRNFL, mlNL measured values were not significantly different (P>0. 05).
●CONCLUSION:AQP4-Ab and ANAs expression in optic neuritis patients is a significant correlation. AQP4-Ab positive patients with optic neuritis pRNFL thinning of macular volume are decreased compared with negative patients.

Objective To study the effect of cholecalciterol cholesterol emulsion(CCE)in the zymosan(Z)-induced acute hepatic injury. Meth-ods A total of 36 C57 BL/6 mice were randomly divided into 4 groups,namely negative control(CON)group,CCE group,Z group and CCE+Z group,respectively. There were 9 mice in each group. Mice from CON group and Z group were fed with pure water. Mice from CCE group and CCE+Z group were fed with cholecalciterol cholesterol emulsion 20μL dissolved in 200 mL pure water which was kept in darkness. After 14 days, Z group and CCE+Z group were injected with zymosan at a dose of 500 mg/kg. After 18 hours,all the mice in each group were sacrificed. The liver tissues were harvested for histopathological examination. The serum ALT levels were determined. The molecular expression of IL-6 and IL-18 in liv-er tissue of mice were evaluated by Western blotting and real-time quantitative PCR method. Results The results of histopathological examination showed that liver tissue damage in CCE+Z group was lighter than that of Z group ,and heavier than that of the CON group. Compared to the CON group,Z group had the highest serum ALT level,followed by CCE+Z group,while in Z group was significantly lower than that in CON group(all P<0.05). The expression of IL-6 and IL-18 protein and mRNA showed level of Z group was apparently higher than those of CON group and CCE+Z group(all P<0.05). Conclusion Cholecalciterol cholesterol emulsion can play certain protective effect on zymosan-induced liver injury in mice.

A 56-year-old female patient of Han nationality presented with generalized erythema and vesicles for 6 days,as well as high fever for 2 days.Twenty days prior to hospitalization,the patient received surgical treatment combined with oral methazolamide and glucocorticoids for glaucoma.The patient had a history of allergy to sulfanilamides.On admission,the patient presented with generalized erythema,vesicles and occasional erosions with bilateral eyelid and oral involvement.Nikolsky's sign was positive.Wheezing sound was heard over the right lung.Genetic testing showed that HLA-B5901 allele was positive.The patient was diagnosed with methazolamide-induced toxic epidermal necrolysis (TEN) complicated by pneumonia,and managed with immunoglobulin (25 g/day,5 days),glucocorticoids (the largest dose equivalent to methylprednisolone 160 mg/day),fresh plasma,antibiotics,as well as other supporting and symptomatic treatments.The condition was controlled after 2 weeks,and the patient was cured and discharged from hospital after 25 days.The fact that the patient carried HLA-B5901 allele suggests that HLA-B5901 is strongly correlated with methazolamide-induced TEN or Stevens-Johnson syndrome in Chinese descendants or Han population,besides in Japanese and Korean descendants.
