AIM: To compare and analyze the stereopsis of intermittent exotropia children under the different backgrounds of dynamic stimuli and static stimuli.
METHODS: We collected 56 children ( male 26, female 30 with intermittent exotropia at the age from 5y to 12y and examined their stereopsis under the different backgrounds of dynamic stimuli and static stimuli using a multidimensional sense perception training software. The differences between the dynamic stereopsis and static stereopsis were compared.
RESULTS: Totally 17 cases ( 30%) had both dynamicstereopsis and static stereopsis, 39 cases ( 70%) had either dynamic or static stereopsis deficit, only 10 cases ( 26%) had dynamic stereopsis, 25 cases ( 64%) static stereopsis left and 4 cases ( 10%) were without any form of stereopsis. The positive rate of dynamic stereopsis was better than the positive rate of static stereopsis, with statistical significance (P<0. 05).
CONCLUSION: Dynamicstereopsis is better than the static stereopsis to intermittent exotropia children.

Endophytic fungi played an important role in the growth of its host plant. To investigate the mycorrhizal characteristics and the distribution of fungi in the root, an endangered wild plant-Dysosma versipellis was collected and observed by electron microscope. The results showed that the host was closely associated with endophytic fungi. The fungi were mainly distributed in the epidermis and cortex. The aseptate and septate fungi with swollen hyphae were observed in some cell of the cortex. The result provides a reference for the study of mycorrhizal structure of Dysosma genus and the interaction between the fungi and its host.

objective To explore the role of cytokines and dendritic cells (DCs) in rat high-risk corneal allograft survival pro- longed by superantigen Staphylococcal Enterotoxin B (SEB) and to compare the different effects between SEB and glucocorticoid. Design Experimental study.Participants Fisher 344 and Lewis rats.Methods The Fisher 344 and Lewis inbred rats were used for high-risk penetrating keratoplasty model.All of the Lewis rat recipients were divided into three groups by blinded fashion.GroupⅠand GroupⅡrats were injected intraperitoneally with 0.2ml saline buffer or SEB (75?g/ml) respectively at 4-day intervals on three occasions before transplantation.GroupⅢrats were injected subconjunctivally with 0.1ml dexamethasone (1mg/ml) daily from the first day after surgery for 2 weeks.The allograft survival was examined under slit-lamp.The concentration of interleukin IL-1?,IL-2,IL-4,IL-5,IL-6, IL-10,TNF-?in rat aqueous humor and peripheral blood were measured by liquichip and the cytokine and CD11c,CD80,MHC-Ⅱex- pression in corneal grafts were examined by immunohistochemestry staining.Main Octcome Measures Mean survival time of the allo- grafts,the level of cytokines in aqueous humor,peripheral blood and corneal grafts.Results Compared with group control,the grafts mean survival time was delayed about 3.8d in group SEB (P=0.00) and 7.1d in group dexamethasone(P=0.01).But there was no signifi- cant difference between group SEB and dexamethone (P=0.26).Liquichip test showed that the level of IL-1?in aqueous humor was re- duced and IL-4,IL-6 and IFN-?,ascended.Only IFN-?,and IL-6 could be found in peripheral blood,and the changing shift of them was similar to that in aqueous humor.The immunohistochemistry staining showed that the expression of IL-2 in rat corneal grafts was signif- icantly decreased but IL-4,IL-6 and IL-10 elevated.The expression of DCs in group SEB was similar to that in group control,which was elevated after keratoplasty,but the phenotype of DCs was not the same.There were predominantly mature DCs in group control while immature DCs in group SEB.Conclusions The immunological inhibiting effect of SEB is same to glucocorticoid,but the mecha- nism is different.SEB can modulate immune response,which might induce immune inhibition via the local production of cytokines and effect on DCs maturation involving corneal graft rejection prevention.

In this paper, the new carbon nanotube modified glassy carbon electrode (F-CNTs/GCE) was prepared to establish a new method for studying the molecular interaction mechanism between baicalin metal complexes (BMC) and bovine serum album (BSA), and the principle of this method was discussed deeply. Under the physiological condition, the thermodynamics and kinetics properties of interaction between BMC and BSA were studied by cyclic voltammetry (CV) to inference their molecular effective mechanism. The results show that the presence of F-CNTs can accelerate the electron transfer, and better response signal was showed in the BMC/BMC-BSA system. The detection of interaction of BMC-BSA used new method show that BMC-BSA generates stable thermodynamically non-covalent compounds, and the obtained average binding sites of BMC-BSA were 1.7; the number of electron transfer in BMC/BMC-BSA reaction process was 2, and non electroactive supramolecular compounds of BMC-BSA were generated by this interacting reaction. The relevant research work provides a new way to study the molecular mechanism for the interaction of drugs with protein, and with a certain reference value for discussion on the non covalent interactions.

Objective To evaluate the capacity of atopy patch test in diagnosis of food allergy in children with atopic dermatitis (AD).Methods Egg and milk,as the most common food allergens among Chinese children,were employed in this study.Skin prick test (SPT) and atopy patch test (APT) with fresh egg and milk were carried out in 68 children with AD.Oral food challenges in an open style were performed to confirm the diagnosis of food allergy.Resuits Of these patients,58(85.3%)were sensitive to egg,40(58.8%)to milk and 34(50.0%) to both.Of 98 patients with positive challenge,47 showed late response,10 immediate reactions.and 41 mixed reactions.The sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV) and the agreement with food challenges in diagnosis of egg/milk allergy were 96.6%/67.5%.90.0%/82.1%,98.2%/84.4%,81.8%/63.9% and 95.6%/73.5%,respectively for APT alone,37.9%/30.0%,100%/89.3%,100%/80.0%,21.7%/47.2% and 47.1%/54.4%,respectively for SPT alone.APT was found to be more sensitive in diagnosis of late-phase reactions than SPT (P<0.01).No significant difference was found in the sensitivity between APT alone and the combination of APT and SPT in parallel algorithm for diagnosis of egg or milk allergy (x2=0.509,0.549,both P>0.05) or in the specificity between APT alone and that in serial algorithm( P=1.000;x2=3.514,P>0.05).Conclusions APT is superior to SPT in diagnosis of late responses to food,and the combination of SPT and APT does not facilitate the diagnosis of food or milk allergy compared with APT alone.

INTRODUCTION:
The aims of this study were to establish weight change, incidence of non-alcoholic fatty liver disease (NAFLD) and cardiovascular risk factors (CvRF) in liver transplant recipients (LTRs).
METHODS:
Eighty-three patients whose mean (standard deviation [SD]) age was 55.6 (8.4) years (median follow-up 73 months) and who underwent their first liver transplantation (LT) at Singapore General Hospital between February 2006 and March 2017 were included in the study. Anthropometric, clinical and demographic data were collected retrospectively from patients' medical records. Diabetes mellitus (DM), hyperlipidaemia and hypertension were regarded as CvRF.
RESULTS:
Compared to baseline, mean (SD) body weight decreased significantly at 1 month post-LT (60.8kg [11.9] versus 64.3kg [13.7],
CONCLUSION
CvRF increased significantly post-LT, and NAFLD occurred in 25.3% of LTRs. Body weight dropped drastically within the first month post-LT, which then returned to baseline level just before the end of first year. This novel finding suggests that nutritional intervention needs to be tailored and individualised, based on events and time from transplant. Although long-term obesity is a significant problem, aggressive oral or enteral nutritional supplements take precedence in the early and immediate post-LT period, while interventions targeted at metabolic syndrome become necessary after the first year.

The osmotic pressure of ammonium sulfate solutions has been measured by the well-established freezing point osmometry in dilute solutions and we recently reported air humidity osmometry in a much wider range of concentration. Air humidity osmometry cross-validated the theoretical calculations of osmotic pressure based on the Pitzer model at high concentrations by two one-sided test (TOST) of equivalence with multiple testing corrections, where no other experimental method could serve as a reference for comparison. Although more strict equivalence criteria were established between the measurements of freezing point osmometry and the calculations based on the Pitzer model at low concentration, air humidity osmometry is the only currently available osmometry applicable to high concentration, serves as an economic addition to standard osmometry.
