Methods Chinese databases including China National Knowledge Internet (CNKI),VIP database,Wanfang Data,China Biology Medicine (CBM) were searched to collect the randomized control trials (RCTs) from inception to November 2014. According to the inclusion and exclusion criteria, the literatures were screened, datas were extracted, and methodological qualities were assessed, then a Meta-analysis was performed by using RevMan software, version 5.3. Results 8 RCTs involved 557 patients were included. The results of this Meta-analysis showed that the elderly tumor patients′quality of life in terminal care patients were superior to that in routine care patients with statistically significant difference [ standardized mean difference was 4.78, 95%confidence interval (95%CI) 2.06-7.50, P<0.01). The satisfaction of patients and their family members in terminal care patients were superior to that in routine care patients and there were statistically significant difference (relative risk was 1.55, 95%CI 1.20-2.00, P<0.01). Conclusions For elderly tumor patients, terminal care can improve their quality of life, and improve the satisfaction of patients and their families.

Objective To investigate the expression patterns of fibroblast growth factor 23 (FGF23) in osteoblast and its responses to calcium, phosphate, exogenous PTH and 1,25(OH)_2D~3. Methods The primary rat calvarial osteoblasts were cultured in MEM medium which containing 10% FBS, then were harvested when cells were in half-confluence, confluence, osteoid deposition and osteoid mineralization stages respectively. The procedure was monitored under microscopy. Total RNA was extracted from cells according to the Trizol procedure. FGF23 mRNA levels were determined by Real-time PCR. Further, the confluent osteoblasts were treated with 3.2 mmol/L CaCl_2, 4.4 mmol/L β-glycerophosphate, 10~(-9) mol/L rhPTH(1-34) and 10~(-8) mol/L 1,25(OH)_2D_3 respectively for 3 days, and same volume of the medium was added as the control. The gene expressions were determined by Real-time PCR. Results FGF23 expression was transiently up-regulated at cell confluent stage and down-regulated after that. The FGF23 mRNA levels were 7.5-fold higher in confluent cells compared with that in half-confluent cells (P<0.001). The markedlly stimulating effect (about 16 times) on FGF23 expression was stimulated by exogenous 1,25(OH)_2D_3 treatment while no significant effect was found on FGF23 mRNA levels by CaCl_2,β-glycerophosphate, and rhPTH(1-34) treatments when compared with the control. Conclusions The FGF23 expression in osteoblast is developmental stage-related and its powerful stimulator is 1,25(OH)_2D.

Objective To explore the patterns of motor and linguistic activation in cortical and its correlations with abnormal gray matter in patients with malformations of cortical development(MCD)and epilepsy.Methods Seven MCD patients with epilepsy(2 patients with focal cortical dysplasia,2 heterotopia,2 schizencephaly,and 1 polymicrogyria)underwent blood-oxygen-level-dependent(BOLD)functional MRI(fMRI)in a 3 T MR scanner when practicing bilateral fingers tapping,toes twisting,verb generation,and picture naming.Functional images were post-processed by using SPM 5 software based on a general linear model(GLM)to generate activations above a uniform threshold with the cluster size (≥30 voxels,P ＜0.001 corrected).The activations were recognized and classified by two experienced neuroradiologists,and then compared with that in abnormal gray matter.Results The clusters and intensities of motor activations were mainly located in the sensormotor cortex(SMC)and premotor area (PMA).In linguistic tasks,activations produced by verb generation were found in language-associated cortical regions and PMA with higher activation in Wemicke area,picture naming significantly in the visual cortex,and language in Broca area.Combination of the two linguistic tasks produced significant clusters and intensities in language cortex.For MCD patients with abnormal cortical abnormalities,motor and language task could produce neuronal activities within normal as well as abnormal cortex regions.In 6 patients who underwent resective surgery,epileptic seizures decreased significantly,and the follow-up images demonstrated no new neurological dysfunctions and cognitive impairments.Conclusions fMRI can visualize neuronal activities in patients with MCD and epilepsy and demonstrate the motor and linguistic activations occurring in normal and abnormal gray matter.It should be cautious for surgery in patient with MCD and epilepsy.

A multi-residue analysis method was developed for the determination of 38 kinds of pesticides in nuts (almonds, peanuts, cashew nuts and walnuts) by QuEChERS-ultra-high performance liquid chromatography-tandem mass spectrometry.The pesticide residues were extracted with acetonitrile.The extract was cleaned up with PSA, C18 and Oasis PRiME HLB, and then analyzed by UPLC-MS/MS with multiple reaction monitoring (MRM) mode.External standard method was employed to quantify.The limits of detection (LODs, S/N=3) of this method were between 0.01 and 10 μg/kg, and the limits of quantitation (LOQs, S/N=10) were between 0.05-20 μg/kg.All of the tested pesticides showed good linear relationship (r>0.991).The practical samples were determined at three spiked levels and the average recoveries were between 51.0% and 126.0%.The RSDs were less than 20%.This method was simple, sensitive and accurate, and could be used for the routine analysis of pesticide residues in nuts.

Objective To establish diagnostic models for pancreatic carcinoma(PC)and to find out the biomarkers related to PC.Methods Serum samples obtained from subjects including PC patients,pancreatic benign disease patients and normal controls were examined with strong anionic exchange chromatography(SAX2)chips for protein profiling using surface enhanced laser desorption/ionization-time of flight-mass spectrometry(SELDI-TOF-MS).The decision tree models and logistic regression models for evaluating the value of serum biomarkers were assessed.SELDI immunoassay and ELISA were used to identify the biomarker and its level in serum respectively.Results Twentysix mass peaks were different between PC patients and normal controls(P＜0.0 1)and 16 mass peaks were different between patients with PC and with pancreatic benign disease(P＜0.05).The decision tree model had a sensitivity of 83.3%and a specificity of 100.0%in differentiation of PC,which was better than that of CA19-9 by ROC curve.There were significant differences in 6 mass peaks among different stages of PC(P＜0.01).Logistic regression model showed a sensitivity of 81.6%and a specificity of 80.6%in diagnosis of early PC.The M/Z 28068 protein was identified as C14orf166 with a sensitivity of more than 82%and a specificity of more than 88%in diagnosis of PC.Conclusions The diagnostic models based on SELDI-TOF-MS were superior to CA19-9 in diagnosis of PC.The identified biomarker C14orf166 is expected to play a role in the diagnosis of PC.

[Summary] The high-risk subjects of type 2 diabetes mellitus ( T2DM) in normal glucose tolerance ( NGT) were screened. The subjects with NGT at baseline were divided into high-risk and low-risk groups according to the diagnostic threshold of insulin area under the curve ( AUCINS ) 108. 43 mU/L. The incidence of prediabetes and/or T2DM was significantly increased in high risk group in comparison with low risk group ( 29. 41 vs 2. 21%, P<0. 01). The result suggests that the diagnosis threshold for AUCINS≥108. 43 mU/L can be used to screen the high-risk subjects of T2DM in NGT.
