Objective To observe exposure rates of hydroxyapatite artificial eye by comparing hydroxyapatite prosthesis implantation through lateral rhinotomy approach on the orbit and traditional sclera shell hydroxyapatite prosthesis implantation.Methods After eye content was enucleated at postoperative stage I,75 patients received hydroxyapatite prosthesis implantation,among which 26 received direct sclera shell prosthesis implantation (group A) and 49 received implantation through lateral rhinotomy approach on the orbit (group B).During postoperative follow-up from 6 months to 5 years,exposure rates of hydroxyapatite artificial eye under two operation ways were observed and analyzed by x 2 test.Results According to observation,8 cases were exposed in the group A,and 2 cases were repaired by fascia and conjunctival repair.Six cases were healed by prosthesis and sclera replacement.In group B,only 1 case was exposed slightly and recovered after simple conjunctival repair.The incidence of the eye exposure rate using two kinds of operation methods in group A is significantly higher than that in group B (P ＜ 0.05) The difference was statistically significant.Conclusion The exposure of hydroxyapatite artificial eye can be effectively avoided and postoperative complications can be reduced by hydroxyapatite prosthesis implantation through lateral rhinotomy approach on the orbit among patients with severe eyeball ruptures,painful eyeballs of no light perception and atrophy eyes.

0.05). For the toxicity,Neutropenia and anemia were common in the three regimens. Thrombocytopenia was significantly mild on the NP regimen. For the PC regimen,gastrointestinal toxicity and nephrotoxicity were mostly mild,and peripheral neurotoxicity was most common. Conclusions:Efficacy was not significantly different between the three investigated regimens. These regimens could be use as first-line chemotherapy in advanced NSCLC. Toxicities of these regimens were different,so clinicians should apply the chemotherapy according to individual characteristics of patients.

Objective:To elucidate the characterization of antigen-specific memory T cells from PPD~+ individuals after stimulation with BCG in vitro.Methods:PBMCs were isolated from PPD~ -/+ normal human peripheral blood and stimulated with BCG. The level of IFN-? in the culture supernatants was assayed by ELISA and the frequency of IFN-?-producinging cells was detected by ELISPOT. The subsets and frequency of cytokine-producing cells were determined at a single cell level by flow cytometry.Results:After stimulation with BCG, PBMCs from PPD~+ but not PPD~- individuals produced significantly high levels of IFN-? in culture supernatants detected by ELISA(P

Neuroglobin(Ngb)is one of the members of oxygen-carrying globin family.It mainly exists in neurons in a monomeric form,which is closely correlated the oxygen supply to brain.Brain hypoxia/ischemia can induce the high expression of Ngb,and as an endogenous neuroprotective factor,it protects ischemic neurons from ischemia/hypoxia injury.This article reviews the distribution,structure and function of Ngb,and its potential protective effects and mechanisms in cerebral ischemia/hypoxia cerebral injury.

Objective:To explore relationship among severity of cerebral infarction (CI) ,arteriosclerosis and serum level of cystatin C (CysC) in young and middle‐aged patients with atherosclerotic cerebral infarction (ACI) .Methods:A total of 82 young and middle‐aged ACI patients treated in our hospital from Feb 2013 to Sep 2015 were enrolled .According to CI volume ,they were divided into small infarction group (n=36 ) , medium infarction group (n=22 ) and large infarction group (n=24);according to CI severity ,they were divided into mild CI group (n=54) and severe CI group (n=28);ac‐cording to atherosclerotic plaque nature ,they were divided into stable plaque group (n=45) and unstable plaque group (n=37) .Another 46 healthy people were regarded as healthy control group .Serum CysC level during emergency period and recovery period and carotid intima‐media thickness (IMT) were measured and compared among all groups .Results:Com‐pared with emergency period ,there was significant reduction in serum CysC level in all subgroups of ACI during recovery period , P<0. 01 all;compared with healthy control group ,there were significant rise in serum CysC level [recovery peri‐od:(0.81 ± 0.24) mg/L vs .(1.03 ± 0.13) mg/L vs .(1.09 ± 0.19) mg/L vs .(1.18 ± 0.10) mg/L] during emergency period and recovery period in small ,medium and large infarction group ,and that of large infarction group was significantly higher than those of small and medium infarction group (P<0.01 all) .Compared with healthy control group ,there was significant rise in serum CysC level [recovery period:(0.81 ± 0.24)mg/L vs .(1.07 ± 0.15)mg/L vs .(1.19 ± 0.16)mg/L] during emergency period and recovery period in mild and severe infarction group ,and that of severe infarction group was significantly higher than that of mild infarction group ,P<0.01 all .Compared with healthy control group ,there were sig‐nificant rise in serum CysC level[(0.81 ± 0.24)mg/L vs .(1.18 ± 0.15)mg/L vs .(1.39 ± 0.27)mg/L]during emergency pe‐riod and IMT [(0.72 ± 0.10) mm vs .(1.24 ± 0.17) mm vs .(1.30 ± 0.14) mm]in stable plaque group and unstable plaque group ,and those of unstable plaque group were significantly higher than those of stable plaque group ,P<0. 01 all .Conclu‐sion:The serum CysC level significantly rises in ACI patients ,it can be used as an index for ACI prevention and treatment .

Objective To describe the burden of caregivers of children with asthma,and to provide reference for the development of family care support program.Methods Qualitative research was used to carry out semi-structured interviews with 13 caregivers of children with asthma in the pediatric outpatient of the First Affiliated Hospital of Guangzhou Medical University.The data collected were analyzed with Colaizzi 7-step analysis method.Results The carcgiver burden was classified into 4 themes,including time and energy exhaustion,heavy economic burden,insufficient knowledge of care and negative emotions.Conclusions The burden of caregivers of children with asthma has a relatively great impact on the daily work and life,even the physical and mental health.Care workers should be concerned about the status of caregiver burden and provide targeted interventions,which could help caregiver adapt to their roles,maintain and promote the health of children patients and their families.

AIM:To observe the effect of oxymatrine on the expression of Toll-like receptor 4 (TLR4) in brain tissue surrounding cerebral ischemic rats. METHODS: The FCI model with thread embolism of middle cerebral artery occlusion (MCAO) in rats was made, 80 male SD rats were divided randomly into shamed-operation, saline and oxymatrine groups, and the oxymatrine group was further divided into two sub-groups which were dealt with the low and high dose of oxymatrine. The expression level of TLR4 and TLR4 mRNA in the brain tissue surrounding cerebral ischemic was determined simultaneously by the usage of immunohistochemical and RT-PCR method respectively. RESULTS: The expression of TLR4 gene in saline group was higher evidently than that in shamed-operation group (P

Objective To investigate the expression and clinical significance of connective tissue growth factor(CTGF) in colorectal cancer.Methods The expressions of CTGF in 62 patients' colorectal cancer tissues and their corresponding adjacent tissues were detected by SP immunohistochemical method.The results were statistically analyzed.Results The positive rates of CTGF in colorectal cancer and adjacent tissues were 61.3% and 19.4% respectively,and the difference between them was significant(P0.05).Conclusion CTGF may play an important role in the occurrence of colorectal cancer,which contributes a lot to guide clinical treatment and prognosis.

Objective:To study the expression of neuroglobin (Ngb) in rat cerebral ischemia model and the neuroprotective effect of Ngb after ischemia and hypoxia. Methods: Totally 113 Sprague-Dawley rats were randomly divided into sham-operated group, middle cerebral artery occlusion (MCAO) group, hemorrhagic infarction (HI) group and hemin treatment group. The brain water content, infarcted tissue volume, neuropathologic changes (H-E staining) and expression of Ngb (immunocytochemical staining) were examined 3, 6, 12, and 24 h after model establishment. Results: The brain water contents and the infarcted tissue volumes in the hemin treatment group were significantly different from those of the MCAO group and HI group (P
