Objective To evaluate the correlation of visual acuity measured using two different types of eye chart in children with amblyopia.Methods 119 cases (213 eyes) amblyopia patients were selected,including 40 cases (80 eyes) of refractive amblyopia,41 cases (58 eyes) of anisometropia amblyopia,and 38 cases (75 eyes) of strabismus amblyopia were selected.Best corrected visual acuity (BCVA) were determined using standard visual chart and visual noise dual chart and the correlation between the two visual acuity result were explored using Spearman's correlation analysis.Results The visual acuity in refractive amblyopia,anisometropia amblyopia and strabismus amblyopia determined by standard visual chart was statistically correlated with that determined by visual noise dual visual acuity chart.Conclusions The visual acuity measured by standard vision chart showed satisfactory linear relationship with that measured by visual acuity chart double among three types of amblyopia,however,the strength of correlation coefficient between different types of amblyopia were different:correlation coefficient in anisometropic amblyopia was the highest,and the coefficient in refractive amblyopia was the lowest.

Objective To investigate the refraction change and nursing character in myopic amblyopia during the perceptual learning treatment. Methods Refraction of 54 children (98 eyes) with myopic amblyopes were selected,which were selected from the amblyopia clinic between 2007 and 2009, the spherical diopter, astigmatism and spherical equivalent were collected before and after perceptual learning,the refractive dynamic was compared according to the degree of amblyopia. Results The spherical average annual growth of myopic amblyopia during treatment was 0.52D, the growth of astigmatism was 0.03D;the spherical equivalent average annual growth was less than 0.50D accounted for 57.14%. The dynamic changes of spherical or SE of mild, moderate and severe amblyopia had significant difference, but the cylinder had not significant difference in change. Conclusions The treatment of perceptual learning in patients has little effect on the growth of refraction in myopic amblyopia, however, it is still necessary to pay close attention to refraction changes of in myopic amblyopia in the course of treatment.

A label-free electrochemical immunosensor using hollow structure nanomaterials based on its ordered porous and big surface area was designed. Au nanocage, with good conductivity, catalysis, and biocompatibility, was prepared and modified on the surface of glassy carbon electrode with graphene to immobilize antibody of microcystin directly. In the absence of microcystin, biosensor can obtain high current response signal of electrochemical probe ( [ Fe( CN) 6 ] 3-/4-. When microcystin was combined with its antibody specifically, the charge density and mass transfer resistance on the surface of electrode increased, resulting in a decrease of the corresponding peak current of [ Fe ( CN ) 6 ] 3-/4-. This change was in proportion to the concentration of microcystin indirectly. Experiment conditions such as cultivation time of antigen and concentration of antibody were optimized. The results showed wide linear range of 0. 05 μg/L-1. 0 mg/L and the detection limit of 0. 017 ng/mL. This sensor has good stability and simple production procedure. This sensor provides a new and simple means for the ultrasensitive determination of microcystins in real water samples.

Epimedin B(EB)is one of the main flavonoid ingredients present in Epimedium brevicornum Maxim.,a traditional herb widely used in China.Our previous study showed that EB was a stronger inducer of melanogenesis and an activator of tyrosinase(TYR).However,the role of EB in melanogenesis and the mechanism underlying the regulation remain unclear.Herein,as an extension to our previous investi-gation,we provide comprehensive evidence of EB-induced pigmentation in vivo and in vitro and eluci-date the melanogenesis mechanism by assessing its effects on the TYR family of proteins(TYRs)in terms of expression,activity,and stability.The results showed that EB increased TYRs expression through microphthalmia-associated transcription factor-mediated p-Akt(referred to as protein kinase B(PKB))/glycogen synthase kinase 3β(GSK3β)/β-catenin,p-p70 S6 kinase cascades,and protein 38(p38)/mitogen-activated protein(MAP)kinase(MAPK)and extracellular regulated protein kinases(ERK)/MAPK pathways,after which EB increased the number of melanosomes and promoted their maturation for melanogenesis in melanoma cells and human primary melanocytes/skin tissues.Furthermore,EB exerted repigmentation by stimulating TYR activity in hydroquinone-and N-phenylthiourea-induced TYR inhibitive models,including melanoma cells,zebrafish,and mice.Finally,EB ameliorated monobenzone-induced depigmentation in vitro and in vivo through the enhancement of TYRs stability by inhibiting TYR misfolding,TYR-related protein 1 formation,and retention in the endoplasmic reticulum and then by downregulating the ubiquitination and proteolysis processes.These data conclude that EB can target TYRs and alter their expression,activity,and stability,thus stimulating their pigmentation function,which might provide a novel rational strategy for hypopigmentation treatment in the pharmaceutical and cosmetic industries.

To investigate whether intrauterine injection of human chorionic gonadotropin (hCG) before the embryo transfer in a frozen-thawed transfer cycle can improve the pregnancy outcome in the patients with repeated implantation failure (RIF).
 Methods: Prospective randomized-controlled trial was adopted. A total of 140 patients, who underwent thawed embryo transplantation and were in line with the diagnosis of RIF, were included. Other patients with some factors, such as uterine malformation, postoperative uterine cavity sticking, tubal effusion, endocrine diseases and endometriosis, were excluded. The patients were randomly divided into 2 groups through the computer random number table: an hCG intrauterine perfusion group and a control group. There was no significant difference in the age, the estradiol level, the number of transplanted embryos, the number of optimal embryos, and the thickness of the endometrium before transplantation between the 2 group (all P>0.05). The hCG+G2 fluid and the G2 fluid were prepared on the day of embryo transfer, and 40 μL of which was injected at an intrauterine site at 3 minutes before embryo transfer in the hCG intrauterine perfusion group and the control group, respectively. The clinical pregnancy rate and implantation rate in the 2 groups were compared.
 Results: The implantation rate and the clinical pregnancy rate in the hCG intrauterine perfusion group were higher than those in the control group (both P<0.05).
 Conclusion: The intrauterine injection of hCG can improve the implantation rate and pregnancy rate in cryopreserved embryo transfer in patients with RIF.

Background: and Purpose The rate of donepezil discontinuation and the underlying reasons for discontinuation in Asian patients with Alzheimer’s disease (AD) are currently unknown. We aimed to determine the treatment discontinuation rates in AD patients who had newly been prescribed donepezil in routine clinical practice in Asia. Methods: This 1-year observational study involved 38 institutions in seven Asian countries, and it evaluated 398 participants aged 50–90 years with a diagnosis of probable AD and on newly prescribed donepezil monotherapy. The primary endpoint was the rate of donepezil discontinuation over 1 year. Secondary endpoints included the reason for discontinuation,treatment duration, changes in cognitive function over the 1-year study period, and compliance as assessed using a clinician rating scale (CRS) and visual analog scale (VAS). Results: Donepezil was discontinued in 83 (20.9%) patients, most commonly due to an adverse event (43.4%). The mean treatment duration was 103.67 days in patients who discontinued. Among patients whose cognitive function was assessed at baseline and 1 year, there were no significant changes in scores on the Mini-Mental State Examination, Montreal Cognitive Assessment, and Trail-Making Test–Black and White scores, whereas the Clinical Dementia Rating score increased significantly (p<0.001). Treatment compliance at 1 year was 96.8% (306/316) on the CRS and 92.6±14.1% (mean±standard deviation) on the VAS. Conclusions In patients on newly prescribed donepezil, the primary reason for discontinuation was an adverse event. Cognitive assessments revealed no significant worsening at 1 year, indicating that continuous donepezil treatment contributes to the maintenance of cognitive function.

One of the distinct hallmarks of cancer cells is aerobic glycolysis (Warburg effect). Lactate dehydrogenase A (LDHA) is thought to play a key role in aerobic glycolysis and has been extensively studied, while lactate dehydrogenase C (LDHC), an isoform of LDHA, has received much less attention. Here we showed that human LDHC was significantly expressed in lung cancer tissues, overexpression of Ldhc in mice could promote tumor growth, and knock-down of LDHC could inhibit the proliferation of lung cancer A549 cells. We solved the first crystal structure of human LDHC4 and found that the active-site loop of LDHC4 adopted a distinct conformation compared to LDHA4 and lactate dehydrogenase B4 (LDHB4). Moreover, we found that (ethylamino) (oxo)acetic acid shows about 10 times selective inhibition against LDHC4 over LDHA4 and LDHB4. Our studies suggest that LDHC4 is a potential target for anticancer drug discovery and (ethylamino) (oxo)acetic acid provides a good start to develop lead compounds for selective drugs targeting LDHC4.
