ABSTRACT
OBJECTIVE:To observe the clinical efficacy and safety of intravitreal injection of ranibizumab combined with argon laser therapy in the treatment of ischemic neovascular glaucoma. METHODS:A total of 166 patients with neovascular glaucoma selected from our hospital during Mar. 2014-Mar. 2016 were divided into control group and observation group according to random number table,with 88 cases in each group(there were 117 and 125 eyes respectively). Both groups received argon laser photocoagulation therapy twice a week for 1 month. Observation group was additionally given intravitreal injection of Ranibizumab injection(0.5 mg)once a week,for 1 month. Clinical efficacies of 2 groups were observed,and the intraocular pressure and visual acuity of 2 groups were observed before treatment,1 week and 1 month after treatment. The occurrence of ADR was recorded. RESULTS:After 1 month of treatment,total response rate was 95.20％ in observation group,which was significantly higher than 76.92％ in control group,with statistical significance (P<0.05). After 1 week of treatment,intraocular pressures of observation group were lower than before treatment and control group at the same time,while visual acuity was better than before treatment and control group at the same time,with statistical significance (P<0.05). After 1 month of treatment,intraocular pressures of 2 groups were decreased significantly and visual acuity was significantly improved;intraocular pressure was decreased and visual acuity was improved more significantly in observation group than control group,with statistical significance(P<0.05 or P<0.01). The incidences of ADR of 2 groups were 3.41％ and 2.27％,without statistical significance (P>0.05). CONCLUSIONS:The ischemic intravitreal injection of ranibizumab combined with argon laser therapy is better than argon laser therapy alone in the treatment of ischemic neovascular glaucoma,and can significantly reduce intraocular pressure and improve visual acuity with good safety.
ABSTRACT
OBJECTIVE:To study the alleviation effect of nervonic acid on movement disorder of model mice with Parkinson's disease(PD). METHODS:Mice were randomly divided into blank control group(normal suline),model group(normal saline), Levodopa and benserazide hydrochloride tablet group (positive control,calculated by L-dopamine 120 mg/kg),nervonic acid low-dose,medium-dose,high-dose groups(20.0,40.0,80.0 mg/kg),10 in each group. Except for blank control group,mice in other groups were inducced for PD models. After modeling,mice were intragastrically given relevant medicines,once a day,for 14 d. After the last administration,behavioral changes of mice in each group were observed. HPLC was conducted to detect dopa-mine(DA)and its metabolites dihydroxybenzoic acid(DOPAC),homovanillic acid(HVA)concentrations in the striatum of mice. RESULTS:Compared with blank control group,climbing time was extended in model group,drum time was shortened,spontane-ous movement times was decreased,and DA,DOPAC,HVA contents in the striatum were reduced (P<0.05). Compared with model group,climbing time was shortened in Levodopa and benserazide hydrochlo ride tablet group,nervonic acid dose groups, drum time was extended,and DA,DOPAC,HVA contents in the striatum were increased(P<0.05);and spontaneous movement times was increased in Levodopa and benserazide hydrochloride tablet group,and nervonic acid high-dose group(P<0.05). CON-CLUSIONS:Nervonic acid can effectively improve symptoms of movement dysfunction of model mice with PD. The mechanism may associate with increasing DA content in the striatum.
ABSTRACT
Objective To compare three different types of donor livers (C-Ⅰ,C-Ⅱ,C-Ⅲ) in clinical efficacy,complications and survival rate of liver transplantation.Methods Using the retrospective descriptive study method,the clinical data of 422 patients undergoing liver transplantation,including 124 cases of C-Ⅰ,81 cases of C-Ⅱ and 81 cases of C-Ⅲ in recent 6 years (from June 2010 to June 2016) were analyzed.The same surgical method was performed with piggyback liver transplantation.Observation indicators contained (1) recipient postoperative liver function;(2) the postoperative complications;(3) the recipient survival rate.SPSS 19.0 statistical software was used for analysis.Results (1) The curative effect was evaluated by the changes of ALT and TBIL among three groups of recipients postoperatively.As compared with C-Ⅰ transplantation group and CⅢ transplantation group,the level of ALT in C-Ⅱ transplantation group was significantly increased (P ＜0.05),the clinical efficacy was poorer.(2) The incidence of PNF was 3.23％ in C-Ⅰ group,9.88％ in C-Ⅱ group and 9.88％ in C-Ⅲ group (P＜0.05).The incidence of acute rejection was respectively 9.68％ in C-Ⅰ group,38.27％ in C-Ⅱ group and 38.27％ in C-Ⅲ group (P＜0.001).The incidence of SIRS was respectively 5.65％ in C-Ⅰ group,39.50％ in C-Ⅱ group and 39.50％ in C-Ⅲ group (P＜ 0.001).There were significant differences in the incidence of other complications among the three groups.(3) There were 14 deaths within 3 months,accounting for 17.28％,and the survival rate was 82.72％ in C-Ⅱ group,the 1-,3-,and 5-year survival rate was 76.55％,74.18％ and 76.55％ respectively in C-Ⅰ group,and that was 88.02％,85.72％ and 81.11％ respectively in C-Ⅲ group.Conclusion Since June 2015,C-Ⅰ donors grow up more quickly on year-on-year basis than C-Ⅱ.Simultaneously,the sort-term and long-term clinical efficacy is better in C-Ⅰ transplantation group than in C-Ⅱ transplantation group.How to repair the three types of Chinese standard donor organs and optimize the quality is still a hot point to ensure the healthy development of organ transplantation in China,which needs further investigation.

ABSTRACT
Background Many ophthalmologists have proved that the intravitreal injection of plasmin can safely induce posterior vitreous detachment(PVD),but if it can generate the complete PVD need further to seek confirmation.Researches showed that the safe dose and toxicity dose of dispase are very near,so its application is limited.Whether hyaluronidase can induce PVD is still in controversy.Objective This study is to clarity the mechanism of pharmacological vitreolysis with plasmin and hyaluronidase.Methods Plasmin 4μmol/L,2μmol/L and 1μmol/L,plasmin 1μmol/L+ hyaluronidase 20μmol/L,hyaluronidase alone were intravitreally injected in lateral eye of 4 clean New Zealand white rabbits respectively,and 0.1mL BSS was injected as control group.Electron immunocytochemical technique was used to detect the laminin and fibronectin of interface between vitreous and retina in 7 days after intravitreal injection.Other 14 eyes of 7 clean New Zealand white rabbits were used in this study.Plasmin 1μmol/L + hyaluronidase 20μmol/L was intravitreally injected in the lateral eyes,and only plasmin 1μmol/L was injected in the fellow eyes.Plasmin activity in vitreous was evaluated in 15 and 30 minutes,1 hour,2,3,6,12 hours after intravitreal injection.The use of animals followed the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The amounts of laminin and fibronectin in the vitreoretinal interface were decreased in 4μmol/L plasmin group,2μmol/L plasmin group,1μmol/L plasmin group,1μmol/L plasmin+20μmol/L hyaluronidase group compared with control group(P＜0.01).No significant difference was seen in the density of gold particles of anti FN between 20μmol/L hyaluronidase group and control group (P＞0.05).The change of amounts of fibronectin in the vitreoretinal interface was similar to that of laminin.Plasmin activity remained the highest level 1 hour after injection and thereafter gradually decreased and extincted in 12 hours and presented the same trend between plasmin 1μmol/L+hyaluronidase 20μmol/L group and only plasmin 1μmol/L group.Conclusion The mechanism of pharmacological vitreolysis is to dissolve laminin and fibronectin in the interface between vitreous and retina and therefore induce PVD.Combination of plasmin with hyaluronidase can increase the efficiency of pharmacological vitreolysis.The optimum selection of drug in inducing PVD should consider not only its role of lysis laminin and fibronectin but also the role of liquefying the vitreous.

ABSTRACT
Binding sites of five monoclonal antibodies were obtained by reinforceable method of overlapping recombinant prion protein and synthetic peptide. Overlapping peptides of PrP core were expressed in Escherichia coli by insertion of serial PCR amplicons of ovine PrP gene fragments into pET32a. The expressed fusion peptides were then tested for the binding activity to PrP monoclonal antibodies in Western blotting. The binding sites of 5 monoclonal antibodies of ovine PrP were located respectively as follows: 2H3 in 199 aa-213 aa, 4C6, 5F11 and 7F11 in 139 aa-168 aa and 7F1 in 214 aa-227 aa. There oligo peptides were synthesized and used in ELISA test for more accurate localization of the binding sites. The binding sites of 4C6, 5F11 and 7F11 were further confirmed to be in 149 aa-158 aa. This conclusion may contribute to the research for pathogenesis and diagnostic method of scrapie and bovine transmissible spongiform encephalopathy.

In order to provide the "guiding principles of clinical research on mild cognitive impairment (MCI) (protocol)" edited by Beijing United Study Group on MCI of the Capital Foundation of Medical Developments (CFMD) with evidence support, clinical criteria, subtypes, inclusion and exclusion of MCI, and use of rating scales were reviewed. The authors suggested that MCI clinical criteria and new diagnosis procedure from the MCI Working Group of the European Alzheimer's disease Consortium (EADC) may better reflect the heterogeneity of MCI syndrome. Diagnostic rating scales including Clinical Dementia Rating (CDR), Global Deterioration Scale (GDS), Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) and Instrumental Activities of Daily Living (IADL) are very useful in definition of MCI but can not replace its clinical criteria. Absence of major repercussions on daily life in patients with MCI was emphasized, but the patients may have minimal impairment in complex IADL. According to their previous research, the authors concluded that highly recommendable neuropsychological scales with cut-off scores in the screening of MCI cases should include Mini-Mental State Examination (MMSE), logistic memory test such as Delayed Story Recall (DSR), executive function test such as Clock Draw Test (CDT), language test such as Verbal Category Fluency Test (VCFT), etc. And finally, the detection of biological and neuroimaging changes, including atrophy in hippocampus or medial temporal lobe in patients with MCI, was introduced.
ABSTRACT
Mild cognitive impairment (MCI), as a nosological entity referring to elderly people with MCI but without dementia, was proposed as a warning signal of dementia occurrence and a novel therapeutic target. MCI clinical criteria and diagnostic procedure from the MCI Working Group of the European Alzheimer's Disease Consortium (EADC) may better reflect the heterogeneity of MCI syndrome. Beijing United Study Group on MCI funded by the Capital Foundation of Medical Developments (CFMD) proposed the guiding principles of clinical research on MCI. The diagnostic methods include clinical, neuropsychological, functional, neuroimaging and genetic measures. The diagnostic procedure includes three stages. Firstly, MCI syndrome must be defined, which should correspond to: (1) cognitive complaints coming from the patients or their families; (2) reporting of a relative decline in cognitive functioning during the past year by the patient or informant; (3) cognitive disorders evidenced by clinical evaluation; (4) activities of daily living preserved and complex instrumental functions either intact or minimally impaired; and (5) absence of dementia. Secondly, subtypes of MCI have to be recognized as amnestic MCI (aMCI), single non-memory MCI (snmMCI) and multiple-domains MCI (mdMCI). Finally, the subtype causes could be identified commonly as Alzheimer disease (AD), vascular dementia (VaD), and other degenerative diseases such as frontal-temporal dementia (FTD), Lewy body disease (LBD), semantic dementia (SM), as well as trauma, infection, toxicity and nutrition deficiency. The recommended special tests include serum vitamin B12 and folic acid, plasma insulin, insulin-degrading enzyme, Abeta40, Abeta42, inflammatory factors. Computed tomography (or preferentially magnetic resonance imaging, when available) is mandatory. As measurable therapeutic outcomes, the primary outcome should be the probability of progression to dementia, the secondary outcomes should be cognition and function, and the supplement outcome should be the syndrome defined by traditional Chinese medicine. And for APOE epsilon4 carrier, influence of the carrier status on progression rate to dementia and the effect of treatment should be evaluated.
