Objective To study the clinical effect of sequent anti-coagnlation treatment of ischemic cerebral vascicular disease. Methods 28 frequent TIA and 30 progressive ischemic stroke patients were studyed.The patients with progressive stroke were given gener- al anti-coagnlation and other common therapy firstly.Those who got worse clinical symptoms and signs received uarfafin orally.The effects of before and after uarfarin therapy were compared.Results Of all the 58 patients,24.1% patients recovered completely,50% improved obviously,17.3% improved and 8.6% had no effects,before and after takeing medicines the score Comparison about neurological impair- ment degree has a highly signifient difference(P

Anterior ischemic optic neuropathy (AION) is the ciliary artery-circulatory disorders for the supply of optic nerve head area before the sieve plate prozone and sieve plate district, result in the insufficient blood supply of the optic nerve head and ischemia hypoxia, edema. Clinical manifestations of the type with non-artery inflammatory neuropathy and artery inflammatory neuropathy, which would both eventually lead to the irreversible damage to the optic nerve. In the early phase of AION, the main method is giving a glucocorticoids intravenous drip and a periglomerular injection (or retrobulbar injection) in time, but using the glucocorticoids for a long time or in quantity can cause a series of complications. Therefore, the combination of traditional Chinese and western medicine treatment of AION has become more and more significant in clinic.

Objective To investigate the expression and significances of DPP-4 and IL-6 in febrile seizures(FS).Methods FS were induced in Sprague-Dawley(SD) rats at P14 in a hot water bath by using classical model of hyperthermia-induced seizures.A genome-wide microarray experiment was generated in the rats.The relationship between the differentially expressed genes were analyzed by the method of bioinformatics, and the gene and protein levels of DPP-4 and IL-6 were detected by QPCR,WB and ELISA.Selected 50 children with FS(FS group) and 25 healthy children(control group), and to compare the gene and protein levels of DPP-4 and IL-6 between the two groups.Results Interaction network diagram of differential gene expression showed that there may be interactions between DPP-4 and IL-6.Animal and clinical experiments showed that the DPP-4 and IL-6 gene and protein levels were significantly higher in FS group compared with control group(P<0.05).Conclusion There were high gene and protein expressions of DPP-4 and IL-6 in the FS group compared with the control group.These results indicated that immune and inflammations may play an important role in the FS, and it has provided an attractive pharmacological target for the treatment of FS in clinic.

Objective:To explore the current situation of clinical nurses' disaster nursing ability and its influencing factors, and to provide basis for carrying out clinical nurses' disaster nursing education and training.Methods:By convenient sampling method, 322 clinical nurses from Peking University Shenzhen Hospital in September 2020 were selected. The disaster nursing ability assessment tool and general information questionnaire were used to conduct a questionnaire survey to analyze the current situation of clinical nurses' disaster nursing ability and its main influencing factors.Results:The total score of disaster nursing ability of clinical nurses was (199.07±34.31) points, which was at the middle and lower level; the scores of each dimension from high to low were as follows: disaster preparedness score was (72.94±12.89) points, coping ability score was (80.00±13.82) points, disaster reduction/prevention capability score was (28.19±6.09) points, recovery/reconstruction ability score was (17.94±3.27) points. Regression analysis showed that the highest degree, clinical department, whether they have autonomously studied disaster nursing related courses after work, and whether they have participated in disaster rescue after work were the main influencing factors of clinical nurses' disaster nursing ability ( t values were -4.715-5.508, P<0.05). Conclusions:The overall level of disaster nursing ability of clinical nurses is at the middle and lower level. It should be combined with clinical nurses' work department, whether clinical nurses have disaster rescue experience and whether they have independently studied disaster nursing related courses, and targeted disaster nursing related training should be carried out to improve their disaster nursing knowledge and skill.

Objective:To investigate the potential effect of hyperopia status on subfoveal choroidal thickness (SFCT) in silicone oil (SO)-filled eyes.Methods:This self-comparative study was conducted in Department of Ophthalmology, Central Theater Command General Hospital. The 50 patients (100 eyes) were collected with unilateral macula-on rhegmatogenous retinal detachment from January 2019 to July 2019, who successfully underwent pars plana vitrectomy (PPV) and SO tamponade. Retinal reattachment was observed after surgery in all patients. One month after PPV, the affected eye was wore soft, contact lenses for 24 hours to correct refractive error (RE), depending on its optometry value. The SFCT of the affected eyes was measured using OCT before and after lenses wear. The fellow eyes also received OCT examination at the same time. T test was used to compare SFCT between SO-filled eyes and fellow eyes.Results:The mean RE of the SO-filled eyes was +6.38±1.12 D. The mean SFCT of SO-filled eyes (247.12±17.63 μm) was significantly thinner than that of the fellow eyes (276.32.55±17.63 μm) ( P<0.001). The SFCT of the SO-filled eyes was significantly thinner than fellow eyes, and the difference was statistically significant ( t=-3.95, P<0.001). After lenses wear, the mean SFCT of the SO-filled eyes increased to 276.32±24.86 μm. Compared with before lenses wear, the difference was statistically significant ( t=-4.30, P<0.001). Compared with the fellow eye, the difference was not statistically significant ( t=0.05, P>0.05). Conclusion:SFCT reduction in the SO-filled eyes may be due to the hyperopia status caused by SO, which can be reserved by RE correction.

The regulator of expression of virion(Rev)protein binds specifically to the Rev-responsive element(RRE)RNA in order to regulate the expression of the human immunodeficiency virus(HIV)-1 genes.Fluores-cence indicator displacement assays have been used to identify ligands that can inhibit the Rev-RRE interaction;however,the small fluorescence indicators cannot fully replace the Rev peptide or protein.As a result,a single rhodamine B labeled Rev(RB-Rev)model peptide was utilized in this study to develop a direct and efficient Rev-RRE inhibitor screening model.Due to photon-induced electron transfer quenching of the tryptophan residue on the RB fluorophore,the fluorescence of RB in Rev was weakened and could be dramatically reactivated by interaction with RRE RNA in ammonium acetate buffer(approximately six times).The interaction could reduce the electron transfer between tryptophan and RB,and RRE could also increase RB fluorescence.The inhibitor screening model was evaluated using three known positive Rev-RRE inhibitors,namely,proflavin,6-chloro-9-[3-(2-chloroethylamino)pro-pylamino]-2-methoxyacridine(ICR 191),and neomycin,as well as a negative drug,arginine.With the addition of the positive drugs,the fluorescence of the Rev-RRE decreased,indicating the displacement of RB-Rev.This was confirmed using atomic force microscopy(AFM)and the fluorescence was essentially unaffected by the addition of arginine.The results demonstrated that RB-Rev can be used as a fluorescent probe for recognizing small ligands that target RRE RNA.The Rev-RRE inhibitor screening model offers a novel approach to evaluating and identifying long-acting Rev inhibitors.
