Objective:To evaluate the role of hemopexin (HPX) in cerebral ischemia-reperfusion (I/R) injury in rats.Methods:One hundred and twenty healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 250-280 g, were divided into sham operation group (S group, n=36), cerebral I/R group (I/R group, n=36), vehicle group (V group, n=24), and HPX group ( n=24). The model of cerebral I/R injury was established by 120 min middle cerebral artery occlusion followed by reperfusion in anesthetized rats.At 6, 12 and 24 h of reperfusion, 4 rats in S group and I/R group were sacrificed, and the ischemic penumbra of the ipsilateral cerebral cortex was obtained to detect the expression of HPX by Western blot.In I/R, V and HPX groups, 0.9% normal saline 10 μl, 0.1% NaN 3 10 μl, and 1.86 mg/ml HPX 10 μl were injected into the lateral ventricle, respectively, immediately after reperfusion.Eight rats in each group were selected, and neurological deficit was scored at 1-7 days of reperfusion.Eight rats in each group were sacrificed at 1 and 7 days of reperfusion, brains were removed, and brain tissues were obtained for measurement of infarct size, and the percentage of infarct size was calculated. Results:Compared with S group, the expression of HPX in cerebral ischemic penumbra was significantly up-regulated at 24 h of reperfusion in I/R group, and the neurological deficit scores were significantly decreased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was increased at 1 and 7 days of reperfusion in I/R, V and HPX groups ( P<0.05). Compared with I/R group, the neurological deficit scores were significantly increased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was decreased at 1 and 7 days of reperfusion in HPX group ( P<0.05), and no significant change was found in the above indicators in V and I/R groups ( P>0.05). Conclusion:Up-regulation of HPX expression is the endogenous protective mechanism of cerebral I/R injury in rats.

Objective:To evaluate the prediction value of preoperative Fibrinogen(FIB) in combination with neutrophil-lymphocyte ratio(NLR)for the prognosis of operable pancreatic cancer patients.Methods:The clinical data of 124 patients who underwent radical resection for pancreatic cancer in our hospital from Jan 2010 to Dec 2018 were retrospectively analyzed.The patients were divided into three groups according the high and low NLR, FIB value which defined by the receiver operating characteristic curve (ROC). The clinicopathological data and overall median survival time were compared between the three groups.Results:Univarate analysis showed that age, tumor stage, NLR, FIB and F-NLR score were associated with the prognosis( P<0.05), while multivariate analysis showed that high F-NLR score was the independent prognostic factor. The median survival time of patients with F-NLR scores 0, 1 and 2 group was 30.6, 20.3 and 13.9 months( P<0.05). The prognosis of high F-NLR score was significantly worse than that of low F-NLR score( P<0.05). Conclusions:A high preoperative F-NLR score was a promising predictor for the prognosis of pancreatic cancer patients after radical resection.

Objective To investigate the esthetic effect of anterior ultra-thin veneers which were fabricated from heat pressed IPS e.max press ingots of high translucency.Methods The whole 62 anterior teeth of 12 patients,who wanted to receive aesthetic restorative treatment,were invloved in the study.Grooves with 0.5 mm depth were marked at the center of the labial face by the use of spherical diamond burs with 1 mm in diameter.At the cervix of the teeth,the design of 0.3 mm shallow concave shoulder was adopted.IPS e.max HT ingots of different color were chosen to be hotpressed; the straining technique was used on the marginal ridge and incisor ridge of the ultra thin veneers after they had been carefully trimmed.Subsequently,the restorations were bonded with Variolink Veneer resin cement.After a short-term follow-up for 3 years,a modified USPHS criterion was used to evaluate the esthetic effect.Results The thickness of the ultra-thin veneers fabricated by heat pressing was 0.3-0.5 mm,marginal integrity of the veneers was perfect and fitted well with the marginal finishing line of the abutment,and then the translucency of veneers was high.There was no edge discoloring after the veneers were used for 6 months to 3 years,and they might produce an excellent chameleon effect by mixing the color of adjacent teeth and gums,and appeared a surface morphology of natural enamel after carefully carved.In the short-term clinical observation,none of the 62 veneers fractured or fell off; there was no case of dentin hypersensitivity.Conclusions Ultra-thin veneers fabricated from IPS e.max Press ingots have the following advantages,a simple operating procedure,high mechanical strength,and satisfactory esthetic effect.

AIM: To observe the therapy effect of standard prescription on ametrop amblyopia in hyperopic children.
METHODS: This study included 270 cases ( 54 eyes ) with complete data, and followed up 24mo. All the amblyopic children were given standard prescription and were divided into progressive addition glass group, under corrected group and full corrected group. And all were observed for their therapy effect and the average healing time in low hyperopic, moderate hyperopic and high hyperopic children with ametropic amblyopia respectively.
RESULTS: In low hyperopic children, the difference of the therapy effect of the three corrected methods were insignificant in two years. The meam cure time of the three corrected methods were ( 7. 33 ± 2. 11 ) mo in progressive addition glass group;(9. 0±3. 71)mo in under corrected grope;(12. 5±5. 17) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=1. 66, P>0. 05) was statistically insignificant; the difference between progressive addition glass group and full corrected grope ( t = 3. 92, P < 0. 01 ) was statistically significant; the difference between under corrected grope and full corrected grope ( t = 2. 33, P < 0. 05 ) was statistically significant. In moderate hyperopic chileren, the differences of the therapy effect of the three corrected methods were significant in two years (χ2=6. 75;P<0. 05). The difference between progressive addition glass group and under corrected grope (χ2 = 6. 3; P < 0. 01 ) was statistically significant; the difference between progressive addition glass group and full corrected grope (χ2=8. 1;P<0. 005) was statistically significant. The mean cure time of the three corrected methods were ( 14. 0±4-87) mo in progressive addition glass group; ( 16. 93±4-58)mo in under corrected grope; (17. 93±4. 42) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=2. 88, P<0. 01) was statistically significant; the difference between progressive addition glass group and full corrected grope ( t= 3. 9, P<0. 01 ) was statistically significant;the difference between under corrected grope and full corrected grope ( t = 1. 01, P > 0. 05 ) was statistically insignificant. In high hyperopic amblyopic children, the difference of the therapy effect and the healing time of the three corrected methods were insignificant in two years. (χ2=2. 43, P>0. 05. t=1. 49, P>0. 05;t=1. 46,P>0. 05;t=1. 11, P>0. 05).
CONCLUSION:Under standard prescription, application of progressive multifocal glasses provides a new effective treatment for ametropic amblyopia in hyperopic children, and makes up the deficiency of the whole straightening and under correction in clinical treatment.
