BACKGROUND:In 2004, a new biomarker sCD14-subtypes (presepsin) was found and its value was shown in the diagnosis and evaluation of sepsis. This article is a brief overview of the new biomarker. DATA SOURCES:A literature search using multiple databases was performed for articles, especially meta-analyses, systematic reviews, and randomized controlled trials. RESULTS:Compared with other markers, presepsin seems to have a better sensitivity and specificity in the diagnosis of sepsis. Presepsin as a biom1arker is not only suitable for the early diagnosis of sepsis, but also for the assessment of its severity and prognosis. CONCLUSIONS:Presepsin has a higher sensitivity and specificity in the diagnosis of sepsis as a new biomarker, and is a predictor for the prognosis of sepsis. More importantly, preseptin seems to play a crucial role as a supplemental method in the early diagnosis of sepsis. Since there is no multicenter study on the relationship between presepsin and sepsis, further studies on the clinical values of presepsin are needed.

OBJECTIVETo study the effect of Jinlida on changes in expression of skeletal muscle lipid transport enzymes in fat-induced insulin resistance ApoE -/- mice.
METHODEight male C57BL/6J mice were selected in the normal group (NF), 40 male ApoE -/- mice were fed for 16 weeks, divided into the model group (HF), the rosiglitazone group ( LGLT), the Jinlida low-dose group (JLDL), the Jinlida medium-dose group (JLDM), the Jinlida high-dose group (JLDH) and then orally given drugs for 8 weeks. The organization free fatty acids, BCA protein concentration determination methods were used to determine the skeletal muscle FFA content. The Real-time fluorescent quantitative reverse transcription PCR ( RT-PCR) and Western blot method were adopted to determine mRNA and protein expressions of mice fatty acids transposition enzyme (FAT/CD36), carnitine palm acyltransferase 1 (CPT1), peroxide proliferators-activated receptor α( PPAR α).
RESULTJinlida could decrease fasting blood glucose (FBG), cholesterol (TC), triglyceride (TG), free fatty acid (FFA) and fasting insulin (FIns) and raise insulin sensitive index (ISI) in mice to varying degrees. It could also up-regulate mRNA and protein expressions of CPT1 and PPARα, and down-regulate mRNA and protein levels of FAT/CD36.
CONCLUSIONJinlida can improve fat-induced insulin resistance ApoE -/- in mice by adjusting the changes in expression of skeletal muscle lipid transport enzymes.

Malignant tumor is one of the main causes for death in the world at present as well as a major disease seriously harming human health and life and restricting the social and economic development. There are many kinds of reports about traditional Chinese medicine patent prescriptions, empirical prescriptions and self-made prescriptions treating cancer, and prescription rules were often analyzed based on medication frequency. Such methods were applicable for discovering dominant experience but hard to have an innovative discovery and knowledge. In this paper, based on the traditional Chinese medicine inheritance assistance system, the software integration of mutual information improvement method, complex system entropy clustering and unsupervised entropy-level clustering data mining methods was adopted to analyze the rules of traditional Chinese medicine prescriptions for cancer. Totally 114 prescriptions were selected, the frequency of herbs in prescription was determined, and 85 core combinations and 13 new prescriptions were indentified. The traditional Chinese medicine inheritance assistance system, as a valuable traditional Chinese medicine research-supporting tool, can be used to record, manage, inquire and analyze prescription data.

OBJECTIVETo evaluate the impact of nicotine- and tar-free cigarette smoke extract (fCSE) on the serum testosterone (T) level and erectile function of male rats.
METHODSWe randomized 30 male SD rats to three groups of equal number to receive subcutaneous injection of PBS (1.0 ml / 300 g body weight per day), fCSE (1.0 ml/300 g body weight per day), and reduced glutathione hormone (GSH, 200 mg per kg body weight per day) in addition to fCSE (fCSE + GSH), respectively, all for 8 weeks. Then we evaluated the erectile function of the rats by measuring the maximal intracavernous pressure (MICP), mean arterial pressure (MAP), ICP/MAP ratio, time of stimulation to MICP (Tmax), and cavernosal filling fate (CFR). We determined the serum T level, the activities of superoxide dismutase (SOD) , malondialdehyde (MDA), and nitric oxide synthase (NOS) in the cavernosal tissue, and also observed the morphological changes of the corpus cavernosum.
RESULTSCompared with the controls, the rats of the fCSE group showed obvious decreases in the levels of serum T ([5.37 ± 1.43] vs [3.22 ± 1.11] μg/L), NOS ([2.90 ± 0.27] vs [1.67 ± 0.18] U/mg) , and SOD ([18.41 ± 1.09] vs [13.36 ± 1.18] U/mg prot) and erectile function-related indexes MICP ([85.92 ± 6.36] vs [58.99 ± 10.76] mmHg), MICP/MAP (0.86 ± 0.09 vs [0.56 ± 0.08]), and CFR (2.14 ± 0.44 vs 0.89 ± 0.44), but markedly increased Tmax ([29.90 ± 5.78] vs [42.90 ± 8.56]s), with a positive correlation between the serum T level and CFR (r = 0. 364, P < 0.05). Masson staining revealed a lower ratio of the corpus cavernosum smooth muscle tissue to collagen fiber in the fCSE group (0.27 ± 0.04) than in the control (0.98 ± 0.12). Compared with the fCSE group, the fCSE + GSH group exhibited significantly improved MICP ([58.99 ± 10.76 ] vs [77.95 ± 7.71] mmHg), MICP/MAP (0.56 ± 0.08 vs 0.77 ± 0.09), and CFR (0.89 ± 0.44] vs 1.76 ± 0.42) and shortened Tmax ([42.90 ± 8.56 ] vs [32.10 ± 5.84 ] s). The ratio of the corpus cavernosum smooth muscle tissue to collagen fiber was higher in the fCSE + GSH than in the fCSE group (0.77 ± 0.09 vs 0.27 ± 0.04) but still lower than in the control (0.98 ± 0.12).
CONCLUSIONNicotine- and tar-free cigarette smoke extract reduces the serum T level and erectile function of rats, which is related to oxidative stress. Antioxidant therapy can improve erectile function but has a limited value for morphological protection of the penile tissue.

Objective To evaluate the influential factors of iron acquisition during Francisella tularensis LVS infection of mouse macrophages.Methods F.tularensis LVS expressing green fluorescent protein was used to infect murine macrophage J774A.1 cells.Transferrin receptor 1(Tfr1)was detected with mono-antibody and visualized with a goat-anti mouse IgG conjugated to Alexa 594.The expression profile of 5 iron metabolism related genes of J774A.1 murine macrophages uninfected or infected with F.tularensis LVS was determined with real-time PCR.Immunoblot analysis was used to compare the Tfr1 expression of live Francisella infected macrophage with dead bacteria.Tfr1 knock-off in J774A.1 cells was performed with siRNA.The transfected cells were infected with Francisella for immunoblotting and microscopy and infection assay.Results It was revealed that the live vaccine strain of F.tularensis induced the expression of Tfr1 in host macrophages.Gene expression analysis indicated that F.tularensis LVS drove an active iron acquisition program with induction of Tfr1 and iron regulatory proteins(Irp1 and Irp2).It was shown by Western-blotting that the siRNA-Tfrc-1 could knock off about 75% of Tfr1 in J774A.1 cells.It was determined by infection assay that,Tfr1 was knocked off,the bacteria number at 1h infection with Francisella was not different from that of control(F=1.06,P=0.326 5),while it was decreased significantly after 24h of infection(F=24.12,P=0.000 6).Conclusions It is demonstrated that upregulation of the Tfr1 may be mediated by post-transcriptional regulation during early infection,but sustained later through increased expression of Irp 1 and Irp 2.Increased expression of Tfr1 expands the intracellular iron pool through transferrin-mediated delivery and may thus be readily available for uptaking by Francisella.Knocking off the expression of Tfr1 does not affect bacterial invasion.Francisella,however,may fail to proliferate in macrophages in which the expression of transferrin receptor has been suppressed.
