Objective To investigate clinical value of inflame factors in child patients with sepsis at different time points before the diagnosis time.Methods A retrospective model was performed in this study.24 child patients with sepsis in Department of Paediatrics from January 2014 to October 2016 were selected.At the time 72 h(group A),48 h(group B),24 h(group C) before the diagnosis time,plasma levels of HBP and serum levels of IL-6,IL-10 were detected by ELISA,and pre calcitonin (PCT) and high sensitive C reactive protein (hs-CRP) were detected by immunofluorescence.Compared to the same period,22 healthy cases were selected as the control.Repeated measure anova and Receiver operating characteristic curve analysis were performed.Results The plasma levels of HBP were (9.69 ± 1.30) μg/L,(12.82 ±2.03) μg/L,(15.46 ± 1.02) μg/L,(18.60 ± 1.10) μg/L at group A,group B,group C before the diagnosis time respectively.The plasma levels of HBP at all time points before the diagnosis time were significantly higher than the control (t =6.27,P ＜ 0.01;t =16.82,P ＜ 0.01;t =25.16,P ＜ 0.01).The serum levels of HBP at group B,group C were significantly higher than the last time point (t =5.62,P ＜0.01;t =10.25,P ＜ 0.01).Receiver operating characteristic curve(ROC) revealed that the areas of HBP at group A(0.823),group B (0.898),was significantly higher than the other inflame factors(Z =2.41,P ＜0.01;Z=2.02,P＜0.05;Z=0.38,P＞0.05;Z=0.32,P＞0.05)(Z=0.43,P＞0.05;Z=0.46,P＞0.05;Z =0.26,P ＞ 0.05;Z =0.57,P ＞ 0.05).It also revealed that at group C,area of PCT(0.941) was significantly higher than the other inflame factors (Z =0.12,P ＞ 0.05;Z =0.08,P ＞ 0.05;Z =0.03,P ＞0.05;Z-0.10,P ＞ 0.05).Conclusions HBP has a wide diagnostic window period for sepsis.IL-6,IL-10,PCT and hs-CRP have diagnostic value in partial periods of sepsis.

Objective To measure and define the distribution of left gastric lymph nodes.Meth- ods From Jan.2004 to Apr.2005,silver clips were set around the root of the left gastric artery in 124 pa- tients with esophageal and gastric cardia carcinoma,X-ray films at 0?and 90?simulator gantry in the radio- therapeutic position were taken.Then,the data of the superior,lower,left,right,anterior and posterior bor- der in each patient was recorded.With SAS 8.02 software,data of minimum area which covered the left gas- tric lymph node in different incidences were obtained.Results According to the analysis of Shapiro- Wilk,Kolmogorov-Smimov,Cramer-von Mises and Anderson-Darling tests,each border was of normal distri- bution,with equal frequency in the male and female,despite the actual results in different genders.Pearson Correlation Coefficients analysis did not suggest a significant relationship between the border and height, weight and size of vertebrae,which formed the minimum area covering the left gastric area at frequency of 100%,95%,90% and 85%,which were drawn out through the calculation.Conclusions Aiming at completely identifying the normal distribution of the left gastric lymph node,more patients are required to be in the pool.For the time being,location in the left gastric area can be obtained from details of the results in the present study.

To investigate the effect of Jiawei Foshou San and its various combined administration on hepatic P450 enzyme activity and hepatocyte morphology in rats. Rats were orally administered with drugs for four weeks and then sacrificed to prepare liver microsomes. The liver microsomes were incubated with the cocktail method; The metabolites were determined with the rapid liquid chromatography with tandem mass spectrometry (LC-MS/MS) to investigate the hepatocyte P450 enzyme activity. In addition, the hepatic pathological changes were observed by using the hematoxylin and eosin (HE) staining. Compared with the control group, the enzyme activity of CYP1A2 and CYP3A4 in the Jiawei Foshou san group showed a significant rise (P < 0.05); the enzyme activity of CYP1A2, CYP2C9, CYP2D6, CYP2E1 and CYP3A4 in the ferulic acid + ligustrazine group and the ligustrazine + tetrahydropalmatine group showed a significant rise (P < 0.05) ; the enzyme activity of CYP1A2, CYP2D6 and CYP2E1 in the ligustrazine group showed a significant rise (P < 0.05); the enzyme activity of CYP3A4 in the ferulic acid group showed a significant reduction (P < 0.05). After the administration with various drugs, the hepatocyte morphologies in the ferulic acid group and the ligustrazine group were normal. The pathological changes were observed in the tetrahydropalmatine group, such as unclear boundary of hepatic lobules, disordered hepatic cell arrangement, blurred edge, anisokaryosis and infiltration of inflammatory cells. The ferulic acid + tetrahydropalmatine group, the ligustrazine + tetrahydropalmatine group and the Jiawei Foshou San group also showed inflammatory infiltration, but with less pathological changes, particularly the Jiawei Foshou San group. The study result shows that Jiawei Foshou San can induce the enzyme activity of CYP1A2 and CYP3A4, and ligustrazine may be the effective substance for inducing CYP1A2. Its combination with ferulic acid and ligustrazine can significantly reduce the liver toxicity of tetrahydropalmatine.

mPem, a homeobox gene, is expressed in a time and stage specific manner during murine ontogeny. Pem transcripts are abundant in 7- and 8-day mouse embryos, but decrease precipitously thereafter. On Day 9 they become abundant in placenta and yolk sac, persisting there until parturition. Although Pem transcripts are not detectable in most of adult tissues, they are present in reproductive system such as testis, epididymis and ovary. This indicates a important role for Pem during embryogenesis and reproductive development. To study the function of mPem protein, we used a GAL4 based yeast two-hybrid assay to screen a 7-day mouse embryo library with full-length of mPem. 3 proteins were found interacting with mPem protein. One of theses is Mdfic. We confirmed the interaction between mPem and Mdfic in yeast and in vitro. Mdfic, MyoD family inhibitor domain containing, encodes the myoD family inhibitor domain (I-mfa domain). The interaction between mPem and Mdfic suggested they maybe form the transcriptional regulator complex to regulate embryo differentiation.

To study the effect of Yinghua Pinggan granule (YHPG) against influenza A/H1N1 virus in vivo and on the immunologic function of infected mice. The intranasal influenza virus infection was adopted in ICR mouse to establish the influenza virus pneumonia model. At the 3rd and 7th day after the infection, the lung index and pathologic changes in lung tissues of mice were detected. Realtime PCR and flow cytometry were employed to observe the virus load in lung tissues and the levels of CD4+, CD8+, and CD4+/CD8+ in peripheral blood. The result showed that at the 3rd and 7th day after the infection, YHPG (15, 30 g x kg(-1)) can significant decrease in the lung index and virus load in lung tissues of mice infected with influenza virus, alleviate the pathologic changes in lung tissues, significantly increase the levels of CD4+ and CD4+/CD8+ ratio and reduce the levels of CD8+ in whole blood. This indicated that YHPG can inhibit the influenza virus replication, alleviate pulmonary damage and adjust the weak immunologic function of infected mice, with a certain therapeutic effect on mice infected by H1N1 virus in vivo.

OBJECTIVETo explore molecular controlling mechanism of mitochondrial injury induced by different density of microwave irradiation.

METHODSRats were exposed to microwave irradiation for 1 hour at average power density of 3 mW/cm(2) or 30 mW/cm(2). After microwave irradiation, the changes of pathological ultrastructure of rat cerebral cortex and hippocampus were observed by electron microscope, and mitochondrial transcription factor A (mtTFA) mRNA expression level were determined by RT-PCR.

RESULTSAfter 3 mW/cm(2) microwave irradiation for 0, 3, 24 h, mitochondrial ultrastructure and mtTFA mRNA expression level didn't significantly change in rat cerebral cortex and hippocampus. After 30 mW/cm(2) microwave irradiation for 0, 3, 24 h, mitochondrial ultrastructure obviously changed, mtTFA mRNA expression in rat hippocampus significantly increased by 67.00%, 80.00%, 30.00% respectively, and in rat cerebral cortex by 133.00%, 86.00%, 233.00% respectively. There were significant differences between the corresponding groups of hippocampus and cerebral cortex (P < 0.01).

CONCLUSIONNo obvious change in mitochondria was found after 3 mW/cm(2) microwave irradiation, but it was found after 30 mW/cm(2) microwave irradiation. Mitochondria injury in cerebral cortex was more severe than that in hippocampus. mtTFA mRNA may have certain regulation in mitochondrial energy metabolism.

BACKGROUNDPulmonary embolism (PE) is a common and often fatal disease. Early after pulmonary thromboembolism, inflammation and associated intimal hyperplasia occur within the pulmonary arteries, similar to what is observed with chronic thromboembolic pulmonary hypertension. This study tested the hypothesis that thrombolytic and anticoagulant agents would have anti-inflammatory effects or inhibit intimal hyperplasia of involved pulmonary arteries.

METHODSSeventy-two male New Zealand white rabbits were randomly divided into two groups (54 rabbits in the PE group and 18 in the sham group). Experimental PE was induced in 54 rabbits by femoral vein injection of autologous blood clots and confirmed with pulmonary angiography, and other 18 rabbits underwent sham operations. Fifty-four rabbits in the PE group were randomly divided into three groups: a control group (treated with normal saline), a low-molecular- weight heparin (LMWH) group (treated with LMWH), and a urokinase (UK) group (treated with UK). Arterial blood gas was analyzed at 2, 7, and 28 days (n = 6 per time point by random group division), then lung tissues were removed and were analyzed for pro-inflammatory cytokines and chemokines, and were stained for intimal hyperplasia.

RESULTSThe overall survival of rabbits undergoing PE was 100%. PE distribution detected on digital signal angiography (DSA) and histopathology was shown in 67% of rabbits (36/54) in the bilateral low lobar pulmonary arteries (PAs). The results showed that alveolar-arterial partial pressure of oxygen (PO2) difference (PA-aO2) significantly increased and PO2 decreased in the control group compared with the sham group. Compared with controls, the UK group had a decreased level of PA-aO2 on day 2 (P < 0.05), however, there was no significant difference in the LMWH group. Compared with controls, the LMWH group had a decreased level of monocyte chemoattractant protein-1 (MCP-1) in affected tissue and serum samples on days 7 and 28 (P < 0.05), and the UK group had decreased levels on days 2 and 7 (P < 0.05). Compared with sham group, all PE groups had an increased level of interleukin-13 (IL-13) and transforming growth factor-β (TGF-β) in unaffected lung tissue samples at days 2 and 7. IL-13 in affected lung tissue in the LMWH group was decreased at all time points compared with controls (P < 0.05). However, TGF-β in affected lung tissue of the LMWH and UK groups increased at day 28. There was less intimal hyperplasia in involved pulmonary arteries at days 7 and 28 in the LMWH group compared with controls; there was no statistical difference in the UK group compared with controls.

CONCLUSIONSUK treatment can rapidly improve the V/Q mismatch in PE and appears a short-term anti-inflammatory benefit. However, LMWH maybe inhibit the later local inflammatory reaction and reduce intimal hyperplasia.

OBJECTIVETo investigate the effects of hydroquinone (HQ) on expression of topoisomerase IIα (TOPOIIα) in human bone marrow mononuclear cells, and to explore the role and possible regulatory mechanism of TOPOIIα involved in toxicity of HQ to hematopoietic cells.

METHODSAfter human bone marrow mononuclear cells were exposed to 50 µmol/L HQ (used the cells which were exposed to sterile distilled water as control); the activity of TOPOII was measured by TOPOII assay kit; the expression levels of TOPOIIα mRNA and protein were detected by RT-PCR technique and Western blotting method respectively; the chromatin immunoprecipitation (ChIP) assay was carried out to study the possible mechanism of TOPOIIα expression changes.

RESULTS(1) The activity of TOPOII was inhibited obviously; the protein and mRNA expression of TOPOIIα were 0.017 ± 0.029 and 0.610 ± 0.128, significantly lower than that in the control with the significant difference (P < 0.01) after treated with HQ for 10 h; (2) The decreased content of TOPOIIα was associated with descended level of histone H4 acetylation than in the control, from 1.198 ± 0.056 to 0.324 ± 0.229, with the significant difference (P < 0.01), without accompanied descended level of histone H3 acetylation, from 1.253 ± 0.045 to 1.177 ± 0.025 (P > 0.05); (3) TOPOIIα mRNA expression decreased gradually after HQ processing, and the chemical modification (histone H4 acetylation) of TOPOIIα promoter happened prior to the mRNA expression.

CONCLUSIONHQ could repress the expression of TOPOIIα in human bone marrow mononuclear cells; the change of histone chemical modification plays an important role in the benzene's hematopoietic toxicity.
