[Objective]To evaluate the efficacy of topical use of 1 g/L tacrolimus eye drops in the treatment of ocular alkali burns.[Methods]A prospective study was performed to evaluate the efficacy of 1 g/L tacrolimus eye drops in the treatment of 12 patients with ocular alkali burns admittedin Zhongshan Ophthalmic Center of Sun Yat-sen University between May 23,2016 and Jan-uary 18,2017. The patients were treated for 1 ~ 18 weeks,with an average of 8.91 ± 5.56 weeks.The degree of ocular alkali burns was evaluated according to Roper-Hall classification system. In this group of patients,there were 2 cases of gradeⅡburns,5 cases of gradeⅢburns and 5 cases of gradeⅣburns. Each patient was given 1 g/L tacrolimus eye drops 2 times a day after admission. The slit lamp microscope and corneal fluorescein sodium staining examination were performed before and 1th week,2nd week,3rd week, 4th week,6th week,8th week respectively after performing topical tacrolimus treatment. Photos were taken to keep records to dynami-cally observe the epithelial repair and anterior segment lesions. Adobe Photoshop CS6 image processing software was used to calculate the area of corneal epithelium repair. The therapeutic effect was evaluated according to the corneal epithelial repair ,visual acuity and complications. The statistical analysis was carried out by SPSS 19.0 software.[Results]4 cases reached good prognosis ,including 2 cases of gradeⅡ and 2 cases of gradeⅢ burns,the corneal epithelium healed and the visual acuity was greater than 0.3. 5 cases had guarded prognosis,including 3 cases of gradeⅢand 2 cases of gradeⅣburns,corneal epithelium healed in 2 cases,corneal epi-thelial repair rate was greater than 50%in 3 cases,in which corneal neovascularization or corneal conjunctiva occurred,and the visu-al acuity was less than 0.3. 3 cases of gradeⅣ burns had poor prognosis:1 had corneal perforation,1 had long term corneal ulcer, and 1 had secondary glaucoma. In 12 cases,the corneal epithelial healing rate reached 99% in 50% patients,and the healing rate was greater than 50%in 75%patients. The visual acuity of 33.3%patients increased by more than three lines,and 66.6%cases had complications. The main factors affecting the prognosis are:The degree of corneal and corneal limbal burns,complication and corneal epithelial repair rate.[Conclusion]1 g/L tacrolimus eye drops can reduce the inflammatory reaction of ocular alkali burns ,reduce the incidence of glaucoma,promote corneal ulcer healing and corneal epithelial repair,and reduce complications caused by corneal lim-bal burns.

Objective To investigate the value of the hippocampal subfield's MRI T2 signal intensity in evaluating the effect of the hydrochloric donepezil for mild cognitive impairment(MCI).Methods 20 MCI patients with hydrochloric donepezil (treatment group) and 20 patients with placebo (control group) were scanned by MRI using FSE-T2 sequence.The margin of hippocampal subfields was outlined manually for each side to measure the MRI T2 signal intensity.The relationship between hippocampal MRI T2 signal intensity and MMSE scores was analyzed in the treatment group.Results Before the treatment, there was no significant difference of the MRI T2 signal intensity between groups.After the treatment, the MRI T2 signal intensity in the bilateral head of the treatment group was significantly decreased compared with the control group(P<0.05).There was an inverse relationship between the MRI T2 signal intensity of the bilateral hippocampal head and MMSE scores in the treatment group(P<0.05).Conclusion The MRI T2 signal intensity in the bilateral hippocampal head could be regarded as a valuable marker in making clinical diagnosis and evaluating the effect of the treatment for MCI in its early stage.

Objective To apply the MRI T2 signal intensity of hippocampal subfield in patients with amnestic mild cognitive impairment (aMCI) as early imageology. Methods From October, 2014 to August, 2015, 20 aMCI patients accepted cognitive training (training group), 20 aMCI patients accepted speech communication (speech group), and 20 age-and gender-matched healthy old people (control group) were scanned with MRI using FSE-T2 sequence. The margin of hippocampal subfields were outlined manually for each side to measure the T2 sig-nal intensity. The correlation between hippocampal T2 signal intensity and the scores of Mini-Mental State Examinatlon (MMSE) was ana-lyzed in the training group. Results Before treatment, T2 signal intensity in the bilateral hippocampal head was significantly high in the aM-CI patients compared with that in the control group (P<0.05). After treatment, T2 signal intensity in left hippocampal head decreased in the training group compared with that in the speech group (P<0.05), similar to the control group (P>0.05). There was negative correlation be-tween left hippocampal head's T2 signal intensity and the scores of MMSE in the training group before and after treatment (r=-0.61, r=-0.54, P<0.05). Conclusion The T2 signal intensity in left hippocampal head may respond to the cognitive function in patients with aMCI in the early stage, that could be used for diagnosis and evaluation in clinic.

Objective To screen the active components of Bushen Huoxue Decoction ( BSHXD) involved in promoting the proliferation of bone marrow mesenchymal stem cells ( MSCs). Methods BSHXD and its subdivisions were extracted with petroleum ether, ethyl acetate, water-free ethanol and water respectively. MSCs were isolated and cultured by the bone marrow adherent method. At the third passage, MSCs were identified by the specific surface markers with immunofluorescence, and their osteogenic and adipogenic differentiation were tested by alizarin red staining and oil red “O” staining. After treated with the extracts of BSHXD and its subdivisions at gradient concentrations for 24 hours, cell viability was detected by methyl thiazolyl tetrazolium (MTT) assay for the screening of active components and optimal concentration. MTT assay was used to describe the growth curve of MSCs treated with the most effective components, and cell cycle was analyzed by flow cytometry. Results Compared with the blank control group, the extracts of BSHXD and its subdivisions could protect MSCs from death to various degrees. Of all the extracts, the ethyl acetate extract of Bushen Division ( BSD) , ethyl acetate extract of BSHXD, ethyl acetate extract of Huoxue Division ( HXD) had the strongest effect, and the effect was dose-dependent, 100 μg/mL being the optimal active concentration while having no any cytotoxic reaction. The results of MTT assay revealed that BSD extracts promoted the proliferation of MSCs significantly and was the most effective component, and then came BSHXD. The results of flow cytometry indicated that BSD extract had the most strongest effect on increasing the amount of MSCs at proliferative phase, and then came BSHXD. Conclusion BSD ethyl acetate extract is the active component of BSHXD for promoting the proliferation of MSCs, showing an effect on increasing the proportion of MSCs at proliferative phase.
