Objective:To investigate the prognostic value of neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and prognostic nutritional index (PNI) before radiation in pancreatic cancer patients underwent radiation therapy. Methods:Clinical data of 61 patients with pathologically confirmed pancreatic cancer were retrospectirely analyzed. Query index values for each patient were clinically tested through electronic medical records. Overall survival (OS) data were collected through electronic medical records or telephone follow-up. Survival curves were compared using Kaplan-Meier methodology and log-rank test. Cox regression methodolo-gy was used for univariate analysis. Results:Using log-rank test and univariate regression analysis, we found that patients with lower NLR, PLR, CA19-9, increased PNI, and lower TNM-staging lived longer than those with increased NLR, PLR, CA19-9, lower PNI, and high-er TNM-staging, and that the difference was statistically significant. Through multivariate analysis, we found that NLR (P=0.029, OR 2.344, 95%CI:1.090-5.041) and PNI (P=0.026, OR 0.477, 95%CI:0.248-0.917) were independent predictors of OS in patients with pan-creatic cancer. Conclusion:NLR, PLR, and PNI are simple, effective, and reliable indicators for evaluating the prognosis of pancreatic cancer.

Background The classical theory from Gass holds that idiopathic macular hole (IMH) is due to the dragging of vitreous cortex in the tangent direction on the macular region,while spectral domain OCT (SD-OCT)studies found that the diameters of inner segment/outer segment (IS/OS) absence (DIOA) region was closely associated with vision ability of IMH patients.Enhanced depth imaging (EDI) is thought to be a new method to study the relation between DIOA and subfoveal choroidal thickness (SFCT) ,but there are few relevant reports.Objective This study aimed to observe the correlation between photoreceptor IS/OS junction and SFCT before and after vitrectomy in IMH by EDI SD-OCT.Methods Forty unilateral IMH patients were enrolled in Affiliated Foshan Hospital of Southern Medical University from June 2011 to June 2013.Vitrectomy (23G) was performed on the patients by the same operator.EDI mode of SD-OCT was used to measure DIOA and SFCT in horizontal direction before and 6 months after surgery.The relationship between DIOA and SFCT was evaluated using Pearson linear correlation analysis.Written informed consent was obtained from each patient before medical assessment.Results IMH was anatomically closed after vitrectomy in 34 eyes with the closure rate 85％.The mean DIOA was (1 280±753) μm in preoperation, which was significantly higher than (656 ± 322) μm in postoperation (t =4.989, P =0.000).The mean SFCT was (130±43)μm in preoperation,showing a slight reduce in comparison with (140±38)μrn in postoperation, but there was not statistical significance between them (t =-1.407, P =0.175).Negative correlations were found between DIOA and SFCT in both preoperation and postoperation (preoperation:r=-0.748 ,P=0.000;postoperation: r=-0.686,P =0.001).Conclusions The alteration of DIOA shows a negative correlation with SFCT in IMH eyes,suggesting a contributing role of the choroid in the change of photoreceptors of IMH.

Objective To analyze the ABCD1 gene mutations in 5 cases of X-linked adrenoleukodystrophy(X-ALD) patients and 2 cases of their mothers.Methods Of 5 patients with X-ALD,10 exons and flanking intronic sequences of ABCD1 gene were amplified by polyme-rase chain reaction,and then sequenced directly.The outcomes were compared with normal ABCD1 sequencings to identify the mutation type and site.Thirty normal men were examined in the mean time as control for the confirmation of mutations and gene polymorphisms.Results Three patients showed ABCD1 gene mutations,1 had a point mutation in exon 6,Arg518Gly(CGG→GGG);2 patients showed the same novel mutation in exon 1 with 8 bases deletion(134del8).Four gene polymorphisms were identified in exon 7.They were Gly551X(GGC→GGT),Arg554His(CGT→CAT),Gln567Arg(CAA→CGA) and Val582Ile(GTC→ATC).ABCD1 gene mutation was not found in 2 mothers from 2 unrelated fa-milies with X-ALD.Conclusions Three cases of 5 were detected for ABCD1 gene mutations.Between them,the 134del8 mutation is a novel one.Four new gene polymorphisms were detected in exon 7 in normal Chinese people,which were Gly551X,Arg554His,Gln567Arg and Val582Ile.

Objective To explore the influencing factors for the purity and viability of primary cultured cortical neurons of rat,and optimize the separating and cultivating conditions of the cortical neurons.Methods The primary cotical neurons were cultured in a serum-free culture system of B27-supplemented neurobasal medium.The differences in purity and viability of primary cultured neurons between embr-yonic rat group and newborn rat [postnatal 24 h and 5 d] group were evaluated by morphology,immunocytochemistry of neuron-specific enolase(NSE) and trypan blue staining.The changes of neurons purity and viability in different trypsin digestion time(0 min,5 min and 15 min) at different environment temperatures(20 ℃ and 30 ℃) were assessed by immunocytochemistry and trypan blue staining.Results The primary cultured neurons from fetal and newborn rats grew well.There was no significant difference in embryonic rat and postnatal 1 d newborn rat group[(91.30?1.03)%,(89.50?1.78)% respectively in purity;and(98.20?0.58)%,(97.10?0.98)% respectively in viability].The neurons from 5-days newborn rat were inferior to that from fetal and 1-day newborn rat in purity and viability[(82.00?1.25)% and(92.87?1.56)% respectively].Shortening operation time and adjusting digestion time according to the environment temperatures could improve neuronal viability:A digestion for 15min at the environment temperature of 20 ℃ or for 5 min at 30 ℃ could acquired cells with higher viability [(98.20?0.58)% and(96.70?0.64)% respectively].Conclusions It is an easy,practical choice to culture priamry cortical neurons from postnatal 1 d newborn rats.Optimizing the separating and cultivating condition(environment temperatures,digest time,et al.) will improve the neurons purity and viability.
