Objective To investigate the effect of astragalus injection combined with beta-adrenoceptor antagonist on serum levels of brain natriuretic peptide ( BNP) , interleukin1β( IL-1β) , IL-6 and tumor necrosis factorα( TNF-α) in the treatment of elderly patients with heart failure. Methods 78 elderly patients with heart failure from April 2013 to April 2015 in department of cardiology of the second hospital of Yuhang district were selected and divided into control group and experimental group with 39 cases in each group.All patients received correction of the electrolyte and acid-base balance and other conventional treatment.The control group received carvedilol by oral, the experimental group received astragalus injection on the basis of control group, with a course of 30 days.The serum BNP,IL-1β,IL-6 and TNF-αlevels pre-and post-treatment in two groups were compared. Results Compared with pre-treatment, the serum IL-1β,IL-6,TNF-α,and BNP levels post-treatment in two groups were lower(P<0.05).Compared with the control group post-treatment, the IL-1β,IL-6,TNF-αand BNP levels in experimental group were lower(P <0.05).Conclusion Astragalus injection combined with beta-adrenoceptor antagonist could significantly improve the clinical sign of elderly patients with heart failure, the mechanism may be reducing the serum levels of IL-1β,IL-6,TNF-αand BNP.

Objective:Comparison of oxygen therapy effect between three different enteral nutrition solutions was carried out on AECOPD patients with non-invasive ventilation.Methods:A total of 96 patients with acute exacerbation of COPD were divided into three groups of 32 respectively according to the admission order in this prospective study:a continuous feeding group,an intermittent feeding group,and a regular bolus feeding group.Arterial blood gas parameters including PH,PaO2,PaCO2,PaO2/FiO2 of three groups on third day,fifth day,seventh day were recorded and compared to evaluate the enteral nutrition effect,and meanwhile nutritional support costs,duration of mechanical ventilation,and length of ICU stay between groups were also studied.Results:PH Values of continuous feeding group and intermittent feeding group on 7th day are7.38 ± 0.04、7.39 ± 0.01 respectively,better than that of regular bolus feeding group (P＜ 0.05).ICU stay period and duration of mechanical ventilation for continuous feeding group are 12.83 ± 3.00 days and 9.50 ± 1.45 respectively,for the intermittent feeding group are 11.90 ± 2.35 and 9.59 ± 1.50 respectively,the two groups gain significant cost-effective advantages compared to the regular bolus feeding group.(P ＜ 0.05),for nutrition support costs,continuous feeding is less than the intermittent feeding.(.P ＜ 0.05).Conclusion:Continuous feeding and intermittent feeding could significantly improve hypoxia symptom and reduce the length of ICU stay and shorten duration of mechanical ventilation in COPD patients compared with regular bolus feeding group.

Objective To investigate the immune protection of heparin-hinding hemagglutinin ad-hesin(HBHA) and to estimate its potential diagnostic value. Methods Native HBHA were used to stimu-late peripheral blood mononuelear cells (PBMCs) from different infected-cases including PPD negative healthy control, PPD positive latent tuberculosis(LTB) infection, pulmonary tuberculosis, and the IFN-γ/in the supernatant of culture was detected. Meanwhile, HBHA specific IgG antibody in the sera was detected by ELISA. Results The middle level of HBHA specific IFN-γ of the three groups were 49.5 pg/ml, 781.9 pg/ml and 341.8 pg/ml, respectively. IFN-γ of latent tuberculosis group was much higher than that of the control, and slightly higher than that of the patients with pulmonary tuberculosis. And the absorbency of the IgG antibody to HBHA in the three groups was 0.212±0.066, 0.224 ± 0.076 and 0.285±0.078. lgG an-tibody in the patients with pulmonary tuberculosis is higher than that of the healthy, including the control and the latent tuberculosis infection. Conclusion HBHA has good immunogenieity, and it can stimulate the LTB to release high level IFN-γ, suggests that the LTB doesn't develop active tuberculosis may rely on its protection. HBHA specific. IFN-γ release may identify 1,333 from the healthy. Anti-HBHA antibody plays an auxiliary role in the diagnosis of pulmonary tuberculosis.

The item scores and the total scores of the disability assessment tool were significantly negatively correlated with the physiological function domain scores and the psychological function domain scores.Conclusion:The function assessment tool based on the ICF′s rehabilitation set when combined with a numerical rating scale has good structural and criterion-related validity in the assessment of disability due to aging.

Objective To explore the clinical characteristics of elderly patients with tuberculous meningitis (TBM) and analyze the causes of misdiagnosis.Methods The clinical data of patients aged 60 years and over with TBM in Beijing Chest Hospital Affiliated to Capital Medical University from January 2011 to January 2017 were retrospectively analyzed.The clinical characteristics of the elderly patients with TBM were analyzed and compared between misdiagnosis and non-misdiagnosis groups.Results Among 60 elderly patients with TBM,32 cases (53.3%) were misdiagnosed before hospitalization.Among 32 misdiagnosed cases,11 (34.4%) were misdiagnosed as pulmonary infection,6 (18.8%) as infectious diseases with unspecified site,4(12.5%) as upper respiratory tract infections and 3 (9.4%) as cerebral vascular diseases,and so on.The onset time of TBM,fever prevalence and CSF glucose levels were 42.5 (20.3,60.0) d,96.9% (31 cases),1.5(1.1,2.3)mmol/L in misdiagnosis group respectively,and 15.0 (10.0,20.0) d,75.0%(21 cases),2.3(1.4,3.2)mmol/L in non-misdiagnosis group respectively,which was statistically significantly different between the two groups (all P< 0.05).There were no statistically significant differences in age,gender,occupation,residence,complications,comorbidities,radiographic signs between the two groups (all P> 0.05).Conclusions Elderly patients with TBM have atypical clinical manifestations,many comorbidities,and less specific imaging,and especially,the cerebrospinal fluid pathogen sensitivity is low,which may result in higher misdiagnosis rate.

Objective To explore the clinical, therapeutic and genetic features of IVD gene in late-onset non-classical isovaleric aciduria. Methods One boy and two girls presented with intractable vomiting were admitted. Urine organic acids and blood acylcarnitines proifles were analyzed. Isovaleric aciduria was diagnosed and conifrmed by IVD gene analysis. The patients were treated with leucine-restricted diet and the supplements of L-carnitine and glycine. Results Three patients had recurrent vomiting, drowsiness, odor of sweaty feet and metabolic acidosis from the age of 1 to 2 years. All of them had normal intelligence and leukopenia. One had oligocythemia. The blood isovalerylcarnitines (4.6 to 8.2μmol/L) and urine isovalerylglycines (36.1 to 1783.56 mmol/mmol creatinine) were elevated. Six mutations were found in their IVD gene. Four mutations (c.157C>T, c.214G>A, c.1183C>G and c.1208A>G) were reported. Two (c.1039G>A and c.1076A>G) were novel. The patients completely recovered after treatment with protein-restricted diet and the supplements of L-carnitine and glycine. Currently, they were aged 19 months to 14 years with normal physical and psychomotor development. Conclusions The clinical features of late-onset non-classical isovaleric aciduria are complex. It is onset in infants and young children and characteristic of recurrent vomiting and metabolic acidosis, which can be diagnosed by the blood acylcarnitine spectrum, urine organic acid analysis, and conifrmed by genetic analysis. L-carnitine supplement and diet intervention has signiifcant effects.

Objective    To analyze the incidence and possible risk factors of the chronic postsurgical pain (CPSP) in patients undergoing cardiac surgery with cardiopulmonary bypass via median sternotomy. Methods    A total of 248 cardiac surgery patients (104 males, 144 females with age of 20–74 years) were enrolled in this single-center, prospective observational study. The severity of acute postoperative pain at first 7 days was evaluated by numeric rating scale (NRS) and pain at 30 days after surgery and CPSP at 3 and 6 months after surgery was evaluated with modified brief pain inventory. Results    The CPSP at postoperative 6 months occurred in 45.2% (112/248) patients and 24.1% of them suffered moderate to severe pain (NRS≥4). The CPSP at postoperative 3 months occurred in 60.9% (151/248) patients and 25.8% of them suffered moderate to severe pain. Moderate to severe postoperative pain at postoperative 30 days and 3 months, and intraoperative remifentanil infusion were the risk factors of the CPSP at postoperative 6 months. Conclusion    CPSP is common in patients undergoing cardiac surgery with median sternotomy. Moderate to severe postoperative pain at 30 days and 3 months, and intraoperative remifentanil infusion can predict the presence of CPSP at 6 months.

PIM (proviral integration site for moloney murine leukemia virus) kinase plays a key role as an oncogene in various cancers including myeloma, leukemia, prostate and breast cancers. The aberrant expression and/or activation of PIM kinases in various cancers follow an isoform-specific pattern. While PIM1 is predominantly expressed in hematological and solid tumors, PIM2 and PIM3 are largely expressed in leukemia and solid tumors, respectively. All of PIM kinases cause transcriptional activation of genes involved in cell survival and cell cycle progression in cancer. A variety of pro-tumorigenic signaling molecules, such as MYC, p21(Cip1/Waf1)/p27(kip1), CDC25, Notch1 and BAD have been identified as the downstream targets of PIM kinases. So far, three kinds of adenosine triphosphate-competitive PIM inhibitors, SGI-1776, AZD1208, and LGH447 have been in clinical trials for the treatment of acute myelogenous leukemia, prostate cancer, lymphoma, or multiple myeloma. This review sheds light on the signaling pathways involved in the PIM kinase regulation and current status of developing PIM kinase inhibitors as clinical success in combating human cancer.

Sepsis is a clinical syndrome caused by the host reaction disorder induced by infection, which leads to serious organ function damage. Sepsis is a serious disease with high mortality, which is the main reason of death caused by infection. Single nucleotide polymorphisms (SNP) is one of the most common genetic variants in human, and is closely related to the genetic susceptibility, early diagnosis, disease development and prognosis of sepsis. This article makes a review on the relationship between CD14, Toll like receptor (TLR), tumor necrosis factor (TNF), interleukins (IL-1 and IL-6), plasminogen activator inhibitor 1 (PAI-1), angiotensin converting enzyme (ACE) and other gene polymorphisms and genetic susceptibility of sepsis, in order to affect in sepsis on the early prediction, diagnosis, and treatment.

Objective To study the change and characterization of metabolic profile of intestinal contents of the neonatal rats with necrotizing enterocolitis (NEC) using metabolomics approach,in order to figure out potential biomarkers of NEC.Method Twenty rats with three-postnatal day-old fed with special formula were assigned to control group (n =8) and NEC group (n =12) randomly.Experimental NEC of rats in NEC group were induced by exposing to cold stimulation at 4 degrees Celsius for 10 minutes and to hypoxia at 95％ nitrogen for 10 minutes,three times a day for three consecutive days.All the rats were sacrificed after model preparation.Segments of the ileum of all the rats were collected for hematoxylin-eosin staining and subsequent pathological damage evaluation.The intestinal contents of the ileum and colon were collected by perfusion,followed by lyophilization and analyzed by UHPLC-QE-MS in order to conduct the non-target metabolomic determination.The information of the metabolites determined was calculated by multivariable analysis using SIMCA software.Result The pathological damage scores of NEC group were higher than those of the control group [(3.13 ± 0.83) vs.(0.25 ± 0.46),P ＜ 0.001].The results of orthogonal partial least squares discriminant analysis (OPLS-DA) model showed that in the ESI + mode,R2(x) =0.604,R2(y) =0.583,Q2 =0.960,while in the ESI-mode,the OPLS-DA model R2(x) =0.828,R2(y) =0.999,and Q2 =0.713,indicating that there is a significant difference in the intestinal content metabolic profile between the control group and the NEC group.Forty-eight differential metabolites related to NEC were identified.In ESI-mode,there were 22 differential metabolites,including L-isoisoleucine (+ 221％) and D-phenylalanine (+ 230％),L-histidine (+ 284％),xanthine (+ 207％),glutamyl leucine (+ 246％),allose (-70％),myristic acid (-57％) and pentadecanoic acid (-35％).What is more,in the ESI + mode,26 other differential metabolites were identified,including ornithine (+ 268％),D-leucine (+ 176％),L-iso Leucine (+ 213％),acetylcholine (+ 195％),nicotinamide adenine dinucleotide (+ 199％),citrulline (+ 158％),cytosine (-58％),xanthoic acid (-64％).These metabolites were reflected to 33 different metabolic pathways in KEGG databases.The pathway enrichment analysis and pathway topology analysis with MetaboAnalyst indicated that the arginine and proline metabolic pathways,histidine metabolic pathways,and glutathione metabolic pathways were the top altered pathways in the condition of NEC.Conclusion The metabolic profile of intestinal contents in NEC rats was significantly different from that in normal rats,which was characterized by amino acid accumulation,mainly involving the metabolic pathways of arginine,proline,histidine and glutathione.The detection of intestinal contents metabolic profile,especially amino acid metabolize group may be of great significance for the diagnosis of NEC,and improving intestinal microenvironment may be the key strategy for the prevention and treatment of NEC.
