Objective To analyze the relationship of the total length of coronary stent and patients’postoperative quality of life. Methods A number of 280 patients who were diagnosed as coronary artery by coronary angiography and successfully completed PCI surgery in our hospital from April 2012 to March 2013 were retrospectively collected.And they were divided into 3 groups according to the total length of the coronary stent,namely:group Ⅰ (68 cases,length of the coronary stent were less than 36 mm),group Ⅱ (156 cases,length of the coronary stent were 36 ~72 mm),and group Ⅲ (56 cases,length of the coronary stent were more than 72 mm).The prognosis and quality of life of patients of the 3 groups were compared.Results There was no significant difference in terms of in-stent restenosis,angina recurrence and target vessel revascularization rates among the 3 groups within 6 months after PCI surgery (P >0.05).But the incidence rate of adverse cardiac events of the 3 groups were significant different,and group Ⅲ were significantly higher than group Ⅱ,group Ⅱwas significantly high-er than in group Ⅰ (P <0.05).It was significant different in terms of the total length of coronary stent aomng the 3 groups (P <0.01).But there was no statistically significant difference in patients’quality of life among the 3 groups (P >0.05).Conclusion Although the total length of coronary stent and patients’postoperative quality of life were of no correlation,it is still recommend to make assessment of vascular lesions carefully before surgery.For patients with stable disease,it is recommend to take conservative medication treatment.Make stent implan-tation only when it’s necessary and the length of coronary stent should be strictly controlled so as to reduce the incidence of adverse cardiac events.

ObjectiveTo explore the childhood trauma experience and its relation to the eye emotion recognition ability in patients with schizophrenia.MethodsSeventy-one schizophrenic patients and fifty-two healthy subjects were assessed with the Childhood Trauma Questionnaire (CTQ) and the Eye Basic Emotion Discrimination Task (EBEDT).ResultsThe CTQ total score in the patients group was significantly higher than those in the control group (47.86 ± 13.26 vs 34.27 ± 7.27,P ＜ 0.01 ).The subscores in emotional abuse,physical abuse,sexual abuse,emotional neglect and physical neglect of CTQ in the patients group were also significantly higher than those in the control group.(all P＜ 0.01 ).Compared with controls,the patients had significantly lower total accuracy( (86.74 ± 6.16vs73.42 ± 11.86) ％,P ＜ 0.01 ) and longer total reaction time ( (2776.75 ± 703.42 vs 4321.40 ± 1956.83 )ms,P ＜ 0.01 )of EBEDT.The significant difference were also found on the accuracy and reaction time of the EBEDT six basic emotion between the two groups ( all P ＜ 0.01 ).Correlation analysis indicated that CTQ total score were negatively correlated with the EBEDT total accuracy ( r=-0.390,P＜0.01 ),and its sub-accuracy of happiness,surprise,sadness,and anger ( respectively r =- 0.419,r =- 0.451,r =- 0.391,r =- 0.344,P ＜ 0.01 ) in the patients group.The correlation between CTQ total score and EBEDT total accuracy was also found in the control group.ConclusionChildhood trauma is related to eye basic emotion recognition in schizophrenia patients,suggesting that the trauma during childhood can affect the social recognition ability.

Objective To evaluate the effectiveness of bioelectrical impedance analysis(BIA) interventions on volume status in hemodialysis patient. Methods Searched The Cochrane Library, PubMed, EMbase, EBsco, Wanfang Data, China Biology Medicine, China National Knowledge Infrastructure to collect clinical trials. The retrieval time was from database to July 15, 2016. The studies were selected according to the inclusion and exclusion criteria and were critically appraised by two reviewers. Then the data of included studies were extracted. Meta-analysis was conducted by using RevMan 5.3 software and descriptive analysis. Results Ten clinical trials were included six random control trial, one controlled clinical trail, three longitudinal study, involving 2009 patients. The results of Meta-analysis showed that the effectiveness of BIA interventions on volume management could improve blood pressure (P=0.001), protect the heart function(left ventricular mass index,P=0.002), compared with the clinical evaluation method, the BIA assessment of dry weight of hemodialysis patients could reduce hospitalization rate 14%. Descriptive analysis showed that BIA intervention volume management had certain advantages for the survival benefit of patients, but the current research was still few, had not yet come to a certain conclusion. Conclusions BIA can improve the management of the volume status and dry weight of hemodialysis patients, so as to it can improve the clinical benefit and survival benefit of patients.Better methods and guidelines for assessing DW and using BIA need to be developed.We propose that experienced HD nursing staff be trained in the use of the BIA to help monitor patient over hydration and approximate dry weight in consultation with the nephrologists responsible for the care of these patients so as to obviate excessive residual over hydration between nephrology reviews.

Aim To explore the protective roles of lic-ochalcone A ( LA) on mice with cigarette smoke-medi-ated acute lung injury and the related mechanisms. Methods In vivo: Mice were exposed to cigarette smoke ( CS) to establish acute lung injury model. The bronchoalveolar lavage fluid ( BALF ) was conducted for cell counting. The mRNA and protein expression of keratinocyte-derived chemokine ( KC ) , tumor necrosis factor alpha ( TNF-α) , interleukin 1β ( IL-1β) and matrix metalloproteinases ( MMP)-9 in lungs were de-termined. The myeloperoxidase ( MPO ) , superoxide dismutase ( SOD ) activities and glutathione ( GSH ) levels in lungs were quantified. The paraffin sections of lungs were prepared and stained with HE. In vitro:Human lung epithelial cells (BEAS-2B) were exposed to cigarette smoke extract ( CSE ) , which induced cell injury. The releases of interleukin 8 (IL-8) and MMP-9 were assessed. The phosphorylation of mitogen-acti-vated protein kinases ( MAPKs, including ERK1/2, p38 and JNK ) and nuclear factor-κB ( NF-κB ) p65 protein were analyzed by Western blot. Results In vi-vo: The accumulation of inflammatory cells was lower in LA groups than that in model group. In comparison with normal control group, the mRNA and protein lev-els of KC, TNF-α, IL-1βand MMP-9 were significant-ly increased in model group. Following treatment with LA, the above indicators were significantly decreased as compared to model group. In the CS-exposed mice, the MPO activity in lungs was significantly increased, meanwhile the SOD activity and GSH level were signif-icantly decreased compared with the air-exposed ani-mals. CS-induced activity of MPO was significantly in-hibited, which were accompanied by increases in SOD and GSH levels by LA. In vitro: CSE-induced mRNA levels of IL-8 and MMP-9 were significantly inhibited by LA at 2 . 5 and 5 μmol · L-1 . The CSE-induced phosphorylation of ERK1/2 and nucleus NF-κB p65 protein expression were prevented by pretreatment with LA. Conclusions LA has protective effects on CS-ex-posed acute lung injury in mice by preventing CS-in-duced pulmonary inflammation, oxidative stress and protease rise. The exploration of the mechanisms sug-gests that LA exerts protective effects via suppressing ERK1/2/NF-κB pathways.

Objective To study any protection against hippocampal neuron damage induced by epilepsy (SE) provided by transcutaneous stimulation (TNS) of the trigeminal nerve and to document any effect of such stimulation on the expression of glutamic acid decarboxylase (GAD) 65/67.Methods Pilocarpine injection was used to induce epilepsy in healthy male Sprague-Dawley rats which were then randomly divided into a treatment group and a model group.Rats which had not received the pilocarpine injection served as normal controls.In the treatment group the rats were given electrostimulation for one month after the first spontaneous seizure following the injection of pilocarpine.In the model group they were given sham TNS for one month.After the month of stimula-tion,immunohistochemistry was used to detect the expression of GAD65/67 in the hippocampus.Terminal deoxy-nucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assays and Nissl staining were applied to deter-mine apoptosis and neuron loss in the hippocampus.Results Significantly less apoptosis was observed in the treatment group than in model group at 24 h,48 h and 72 h post-injection.Compared to the model group,average GAD65/67 expression had increased significantly in the treatment group at 24 h,72 h,1 week,2 weeks and 4 weeks post-stimulation.GAD65 expression reached its peak from 72 h to 1 week post-stimulation,then decreased to the level of the control group by 4 weeks post-stimulation.The expression of GAD67 remained elevated at all the time points employed.Conclusions TNS can significantly protect hippocampal neurons from damage in epilepsy,at least in rats.The underlying anti-epileptic and neuroprotective mechanisms may involve increased inhibitory transmission induced by the stimulation.

Objective To investigate the common chromosome abnormalities in the patients with multiple myeloma and the relationships of cytogenetic abnormalities and clinical features. Methods The interphase fluorescence in situ hybridization (I-FISH) analysis method was designed to detect RB1-/13q14-and 14q32 rearrangements in 49 MM patients. The statistic value of its effect on clinical features were determined. Results FISH disclosed 14q32 translocations in 26 of the 40 (53.1%) patients. 25 out of the 49 (51.02 %) cases were found with deletion of chromosome 13q14 included del(RB1) in 9 (18.4 %) and del(13q14.3) in 18 (36.7 %). 13q14 deletion and 14q32 translocation were simultaneously observed in 18 (36.7 %) cases. Spearman correlation analysis were found associated of 14q32 rearrangement with the percentage of plasma cells in bone marrow (r=0.316, P=0.27). Conclusion The frequency of 13q14 deletion and 14q32 gene translocation in multiple myeloma are high. There is a significant correlation between the presence of 14q32 translocations and chromosome 13 abnormalities in MM patients. The percentage of 14q32 translocation in plasma cells was increased significantly. The 14q32 translocation is an independent prognostic factor.

Objective To investigate the mechanism of hypoxia regulate osteopontin (OPN) secreting by mature dendritic cells (mDCs). Methods CD14 + cells were enriched using anti-CD14 immunomagnetic beads, for inducing to mDCs, CD14 + cells were cultured with GM-CSF and IL-4 in hypoxia or normoxiain vitro. Concentration of OPN and TGF-β1 in supernatant were detected by sandwich ELISA, OPN mRNA detected by RT-PCR. Approach regulating function of A2 R in expressing of OPN by mDCs by using NECA (surrogate of adenosine), A2R agonist (CGS21680), A2R antagonist (SCH58261) and investigate role of TGF-β1 in this process by using rhTGF-β1 and anti-TGF-β1 Ab. Results Hypoxia inreased the level of OPN and OPN mRNA in mDCs, and this effect could be reversed by A2 R antagonist. Under normoxia,both NECA and A2R agonist (CGS21680) could upregulate the level of OPN and OPN mRNA in mDCs significantly, but this positive effect could be reversed by A2 R antagonist. A2 R played a role in regulating TGF-β1, and confirmed TGF-β1 involved in regulation of OPN by using rhTGF-β1 and anti-TGF-β1 Ab. Conclusion High adenosine induce the generation of TGF-β1 through the A2R on mDCs, and then TGF-β1 raise the OPN secreting by mDCs.

Attention is an essential cognitive function which was use to perceive the external world, and it is the basis of all cognitive activities.Other cognitive functions such as working memory, executive function, information processing speed and so on, are also adversely affected in hypoprosexia or hyperfocusing state.Patients with schizophrenia have severe attention disorder, which makes patients unable to successfully complete the task of work or study, thus reduce the quality of life.Attention disorder exists throughout the whole course of this disease, and there is no specific drug for it.In recent years, antipsychotic medications have widespread application, but it has not shown up significantly improvement of attention disorder, worse still, its side effects will exacerbate the disease, which results in the impairment of the patients' ability to learn and explore the novelties.Neuroimaging markers of attention disorder in schizophrenia are the focus of current researches.White matter fibers are important pathways that connect attention networks and maintain the three-dimensional structure of the brain.Previous studies have suggested that attention disorder may be related to abnormalities of white matter fibers connecting various encephalic regions.In particular, abnormalities in the integrity of white matter, such as corpus callosum, cingulum bundle, superior longitudinal fasciculus, inferior fronto-occipital fasciculus, have been reported to be significantly associated with attention disorder in patients with schizophrenia.In this study, the relationship between attention disorder and white matter structure in patients with schizophrenia is reviewed through diffusion tensor imaging (DTI) technique.
