This paper deals with the analysis of the phospholipids and fatty acids in Hippocomnpus kelloggi Jordan et Synder, H. Histrix Kaup, II. trimaculalus Leach, II. kuda Bleeder, II. japonicus Kaup, Solenognathus hardwickii(Gray), Syngnathoides biacufcatus(Bloch) and Tracliyrliamphus serralus (Temminck &. Schlegel).The total phospholipids were extracted with Folch solvent and determined by molybdate blue spec-trophotometric method. The result showed that the contents of total phospholipids in these spccimins were 2. 56-7. 82mg/g.The nine kinds of phospholipid standards of absorbance proportional coefficient were detected in this paper. The phospholipid components were separated and determined by using thin - layer chro-matographic method and Vaskovsky solvent as a specific spray reagent. The quantitative analysis of the distribution of various phospholipids components in these specimen ts were carried out, by using TLC scanning and the corrective method of absorbance proportional coefficient. The resut showed that the Hippocampus contains about five phospholipids: lysophosphatidylcholine, sphingornyelin, phophatidylcholine, phosphatidylinositol, and phosphatidylethanolamine. The phosphatidylserine , phosphatidylglycerol, diphosphatidylglycerol and phosphatidic acid were more in Syugnathus than in Hippocampus, But in all these specimens, the main phospholipid components were lysophos- phatidylcholine, sphingornyelin and phosphatidylcholine.Fourteen fatty acid compositions in these specimens were analysed by GC -MS -DS. The result showed that the main fatty acid were hexadecanoic acid, 9 - octadecenoic acid, 8,11- octadeca-dienoic acid and 1,7,10,13,16,19 - docosahexaenoic acid.

BACKGROUND:Cardiopulmonary exercise test plays a significant role in the evaluation of cardiopulmonary function, but it is limited by expensive equipments and professional personnel, and moreover, the subjects need to bear the maximal exercise intensity. As a result, it is extremely urgent to find a submaximal exercise test characterized by simple operation, low cost and easy to be popularized and used. OBJECTIVE:To compare the maximal oxygen uptake in cardiopulmonary exercise test and 6-minute stair climbing and descending test. METHODS:Sixty-seven volunteers were recruited to undergo the cardiopulmonary exercise test using the Bruce protocol, and then, the maximal oxygen uptake was detected. After that, al the participants were subjected to 6-minute stair climbing and descending test, folowed by determination of the maximal oxygen uptake. RESULTS AND CONCLUSION:The maximal oxygen uptake in the cardiopulmonary exercise test was significantly higher than that in the 6-minute stair climbing and descending test (P < 0.01), and there was a highly positive correlation and consistency between the maximal oxygen uptakes in the two tests (r=0.911,P < 0.01). Therefore, 6-minute stair climbing and descending test can be used to detect the maximal oxygen uptake, which may become an effective method for evaluating cardiopulmonary function.

AIM: To investigate the effect of 17?-estradiol(E2) on myocardial hypertrophy induced by endothelin-1(ET-1) and the related mechanism.METHODS: Myocardial cells from neonate rats were cultured in vitro and myocardial hypertrophy model was established with ET-1.The effects of 17?-estradiol on myocardial hypertrophy were observed.The role of ERK1/2 in the effects of 17?-estradiol was also detected.RESULTS: Compared with control group,ET-1 increased cell protein content,cell surface area and -Leucine(-Leu) incorporation.Pretreatment with E2 for 24 h could inhibit the increase in cell protein content,cell surface area and -Leu incorporation induced by ET-1.ET-1 significantly stimulated ERK1/2 activity,which was prevented by pretreatment with E2.Tamoxifen,estradiol receptor antagonist,partially inhibited the effect of E2.The ability of ET-1 to stimulate -Leu incorporation was significantly blocked by PD98059,which could enhance the inhibitory effect of E2 on the increase of -Leu incorporation in cardiomyocytes induced by ET-1.CONCLUSION: E2 can inhibit cardiomyocyte hypertrophy induced by ET-1.This effect is mediated by estrogen receptor.ERK1/2 signal pathway is closely correlated with the inhibitory effect of E2 on cardiomyocyte hypertrophy induced by ET-1.

Objective To investigate the correlation between Dishevelled protein expression and the proliferation and invasion of glioma cells.Methods 67 cases of brain glioma specimens were collected.The expression of Dishevelled protein was detected with immunohistochemical method.The immunoreactivity score (IRS) of Dishevelled protein,and proliferation index (PⅠ) and invasion index (Ⅱ) were measured and their correlations were analyzed.Results The positive rate of Dishevelled protein in glioma was 65.7 ％ (44/67).IRS,PⅠ and Ⅱ were 4.15±3.13,(30.93±17.92) ％,(20.38±13.36) ％,respectively.Both PⅠ and Ⅱ significantly increased with an increase in the pathological grade of brain glioma (P ＜ 0.001).Furthermore,PⅠ and Ⅱ were significantly higher in the Dishevelled protein-positive group than those in the Dishevelled protein-negative group [(38.27±17.60) ％ vs (16.02±8.92) ％ of PⅠ and (30.03±13.81) ％ vs (10.63±4.41) ％ of Ⅱ,respectively,P ＜ 0.001].PⅠ and Ⅱ of glioma cells were positively correlated with IRS of Dishevelled protein (r =0.940 between PⅠ and IRS,and r =0.953 between Ⅱ and IRS,respectively).Conclusion Dishevelled protein plays an important role in the proliferation and invasion of brain malignant glioma.

Mitogen-activated protein kinases (MAPKs) are important signaling transduction components well conserved in eukaryotes and play essential roles in various physiological, developmental and hormonal responses in plant. In the present study, a MAPK gene, designated as DoMPK4 (GenBank accession No. JX297597), is identified from a rare endangered medicinal orchid species D. officinale using the reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) methods. The full length cDNA of DoMPK4 is 1 518 bp in length and encoded a 369 aa protein with a molecular weight of 42.42 kD and an isoelectric point of 5.55. DoMPK4 protein contained a serine/threonine protein kinase active site (158-170), a MAP kinase site (71-174), and eight conserved motifs. DoMPK4 had a transmembrane (214-232) but no signal peptide. Multiple sequence alignment showed that DoMPK4 shared high identities (74.9%-80.6%) with MAPK proteins from various plants. Phylogenetic analysis demonstrated that DoMPK4 belonged to group A of the MAPK evolutionary tree, and is closely related to monocots. Real time quantitative PCR (qPCR) analysis revealed that DoMPK4 is differentially expressed among the five organs including leaf, stem, root, seed, and protocorm-like body (PLB). The transcription level of DoMPK4 is the highest in the PLBs with 17.65 fold, followed by seeds, roots, and stems with 5.84, 2.28, and 1.64 fold, respectively. The progressive enhancement of DoMPK4 transcripts in the developing PLBs compared to that in the germinating seeds, suggests a role of DoMPK4 during the development of embryogenic PLBs formation in D. officinale.

Objective To investigate the clinical parameters,risk factors,treatment and clinical outcomes of pneumocystis pneumonia(PCP) in children without human immunodeficiency virus(HIV). Methods Retrospective a-nalysis was made for the clinical features,risk factors,treatment and prognoses of the non-HIV infected severe PCP pa-tients hospitalized at Pediatric Intensive Care Unit( PICU) of Children′s Hospital Affiliated to Capital Institute of Pedi-atrics. Results During April of 2010 to April of 2014,there were 10 cases of non-HIV infected severe PCP in PICU of Children′s Hospital Affiliated to Capital Institute of Pediatrics. All of the patients had predisposing diseases,in which 3 cases had connective tissue diseases,2 cases had acute leukemia,3 cases had severe pneumonia and 2 cases had con-genital immunodeficiency. The main clinical manifestations of those 10 patients were fever, cough, tachypnea and obvious dyspnea. All patients developed respiratory failure. The median value of Pediatric Critical Illness Score was 79. The median arterial oxygen pressure was 58 mmHg(1 mmHg=0. 133 kPa). The median oxygenation index was 103 mmHg. The median alveolo-arterial oxygen partial pressure difference was 43. 8 mmHg. The median CD4+T-lympho-cytes counts was 169 ×106/L. Eight patients on admission had mixed infection. Acute respiratory distress syndrome (ARDS) occurred in all of the patients,and 7 cases of them had multiple organ dysfunctions. All of the patients re-quired ventilation support. The median day for invasive mechanical ventilation days was 11 and the median day for non-invasive ventilation days was 6. The pneumothorax occurred in 5 patients. All patients received trimethoprim-Sulfame-thoxazole as initial therapy and Caspofungin treatment in combination in 7 cases of the patients. Six patients had nosoco-mial infection. The median time of PICU stay was 15. 5 days. Six patients survived and the mortality was 40%(4/10 cases) . Conclusions PCP is a kind of fatal diseases which occurred in patients with immunocompromised conditions and concurrent ARDS or multiple organ dysfunctions. Diagnostic suspicion and mechanical ventilation therapy with lung protective ventilation strategies may improve the clinical outcomes of non-HIV-infected PCP in children.
