Ocular ischemic syndrome(OIS) is a disease seen in cardiology,ophthalmology,neurology and neurosurgery,which is characteristic by brain and ocular symptoms caused by carotid artery obstruction or stenosis.The diagnosis of OIS may be difficult because of its variable presentations and its concealed onset.What is more,its pathogenesis is not completely clear,and therefore its treating efficacy is dissatisfactory so far.The current study on OIS is focused on experimental research.So establishment of suitable animal model is important.Recently years,the creating method of OIS model made a great progress.The selection of model animals,extablishing methods of models and comparison of various models were summarized.

Objective To investigate the low back pain(LBP)of clinic nurses and find out the understanding of related knowledge of LBP in nurses,and improve the occupational protection of nurses.Methods Investigation was carried out in 692 nurses by self-designed questionnaires.Results The incidence of LBP in nurses was 97.4%.The knowledge of LBP and the related occupational protection in nurses were greatly deficient.Conclusions The hospital should pay attention to the protection of LBP in nurses and improve their health.

Background Fungal keratitis can cause serious damage to visual function of corneal infective disease,which is more difficult to treat.In recent years,injecting antifungal drugs to the corneal stroma not only enrich the treatment of the disease,but also achieve good clinical effects.Correctly selecting drug kinds and drug concentration can improve the cure rate,and reduce adverse reactions after treatment,but the related research is rare.Objective This study was to observe the clinical effects of corneal stroma fluconazole injection with different concentration for the treatment of fungal keratitis.Methods Prospective study was performed.One hundred and two patients (102 eyes) diagnosed as fungal keratitis were included from May 2012 to January 2015 in Jizhong Energy Xingtai Mining General Hospital.The patients were randomly divided into 3 groups,The eyedrop treatment group (29 eyes) received 0.5％ fluconazole eyedrops and 5％ natamycin eyedrops treatment.The 0.1％ fluconazole group (35 eyes) and 0.2％ fluconazole group (38 eyes) received 0.1％ and 0.2％ fluconazole corneal stroma injection after eyedrop treatment,respectively.Each group underwent potassium hydroxide wet examination and fungal cultures.The curative effect and adverse reactions were observed.Results Fusarium 41.2％ (42/102),Aspergillus 21.6％ (22/102)and Alternaria mold 17.6％ (18/102) ranked the top three pathogenic species.The distribution of pathogenic fungus among the 3 groups were significantly different (x2 =3.763,P＞0.05).The cure rate of eyedrop treatment group was 44.8％ (13/49),which was significantly lower than 0.1％ fluconazole group (74.3％,26/35) and 0.2％ fluconazole group (81.6％,31/38) (x2 =5.782,9.854;both at P＜0.05).The cure rate was significantly different between 0.1％ fluconazole group and 0.2％ fluconazole group (x2=0.566,P＞0.05).The average cure time of eyedrop treatment group,0.1％ fluconazole group and 0.2％ fluconazole group were (36.28 ± 10.39),(29.14± 7.86) and (21.34 ± 8.57) days,respectively,with a significant difference among the three groups (F =5.336,P=0.006).The acuity of vision was significantly increased after treatment in the 0.1％ fluconazole group and 0.2％ fluconazole group (t =3.009,4.695;both at P ＜ 0.01).The average number of injection in the 0.1％ fluconazole group was (5.71 ± 2.97) times,which was higher than (5.13 ± 1.80) times in the 0.2％ fluconazole group (t=4.471,P＜0.05).Four cases in 0.2％ fluconazole group with eye irritation were observed.After diclofenac sodium eyedrops treatment,the symptoms of 3 cases were disappeared.One case was cured by conjunctival flap covering method.All the cases were followed up for 1-3 months,no adverse reactions and recurrence was found.Conclusions Corneal stroma fluconazole injection is an effective method for treatment of fungal keratitis.In order to reduce the occurrence of adverse reactions,0.1％ fluconazole injection in corneal stroma is recommend for light fungal keratitis patients;for moderate and heavy fungal keratitis patients,0.2％ fluconazole injection in corneal stroma can be performed after failure of 0.1％ fluconazole treatment.

Objective:To study the expression of IQ motif containing GTPase activating protein 1 (IQGAP1 )in oral squamous cell cancer(OSCC)tissue,and to explore the effects of IQGAP1 on cell proliferation and invasion as well as its underlying mechanism. Methods:Expression levels of IQGAP1 in tumor and adjacent normal tissues were examined by western blot and RT-PCR.OSCC cell line SCC-4 cells was transfected with the recombinant plasmid-pcDNA3.1 -IQGAP1 by lipofectamine,and then treated with an Akt in-hibitor.The phosphorylation of Akt,cell proliferation and invasion were detected by western blot,MTT assay and Transwell invasion as-say respectively.Results:Protein and mRNA expression levels of IQGAP1 were higher in cancer tissue than in adjacent normal tissue (P <0.05).Transfection of pcDNA3.1 -IQGAP1 increased IQGAP1 expression,enhanced the capability of cell proliferation and inva-sion (P <0.05),increased p Akt level in the cells.Preconditioning with an Akt inhibitor reduced p Akt level.Furthermore,silencing Akt pathway blocked the increase of cell proliferation and invasion induced by IQGAP1 overexpression(P <0.05).Conclusion:IQ-GAP1 overexprission can mediate the ability of proliferation and invasion of OSCC cells by regulating the activation of Akt pathway.

The whole process of mini-implant was introduced, including preparation, operating methods, points for attention during the procedure, post-operation of implanting and the medical orders. Principles of implanting position and eight normal positions of implanting were introduced. These might be useful for clinical application.

Objective: To reasonably adjust the medical prices on the basis of cancelling drug prices policies. Methods: Taking the data from sample hospitals in Guangdong as example, to discuss how to establish model of medical service item pricing scientifically and reasonably. Results:The model of medical service item pricing has been established and practical care has been estimated. Conclusion:It needs to adjust the charging of medical technical services to achieve the prospective effects of medical reform.

The rise in childhood obesity has lead to an increased number of children with lipid abnormalities,and the predominance of a combined dyslipidemic pattern characterized by a moderate-to-severe elevation in triglycerides,normal-to-mild elevation in low density lipoprotein cholesterol and reduced high density lipoprotein cholesterol.Most of the published guidelines focus on managing primary dyslipidemia in pediatric patients,there is still no general consensus regarding the treatment of obesity-related lipid abnormalities in children.This article reviews screening,diagnosis and management of dyslipidemia associated with obesity in children,and emphasize lifestyle change is critical,in the rare child for whom diet and exercise interventions are insufficient,there are medication options that can be considered.

Objective:To discuss the curative effect of Saccharomyces boulardii Sachets in the treatment of children with hand-foot-mouth disease (HFMD) and explore the influence on serum procalcitonin (PCT) and interleukin-6 and 12 (IL-6 and 12) levels. Methods:Totally 88 cases of children with HFMD were selected and divided into the observation group and the control group at ran-dom. The children in the two groups were given routine medical treatment, such as anti-virus, defervesce, nutrition support and etc. The children in the observation group were additionally given 0. 25g Saccharomyces boulardii Sachets, once a day with warm boiled wa-ter. The changes in serum PCT, IL-6 and 12 levels of the children before and 72 hours after the medical treatment were observed, and the clinical curative effect and adverse reactions were compared as well. Results: After the 72-hour medical treatment, serum PCT, IL-6 and 12 levels of the children in the two groups were declined in different degrees (P<0. 05 or P<0. 01), and the declining rate in the observation group was much higher than that in the control group (P<0. 05). The total clinical efficiency of the observation group was also much higher than that of the control group. The adverse reactions appeared respectively in the control group and the ob-servation group during the medical treatment show no significant difference(P>0. 05). Conclusion:Saccharomyces boulardii Sachets used as adjunctive therapy show favorable curative effect and safety in the treatment of children with HFMD, which can reduce serum PCT, IL-6 and 12 levels, and inhibit the immune inflammatory reaction process in children.
