Objective To investigate the value of global longitudinal strain (GLS) in detecting severe coronary artery stenosis (SCAS) in patients with coronary artery disease. Methods Fourty-two patients with SCAS confirmed with coronary arteriongraphy (CAG) underwent two-dimensional strain echocardiography. GLS, wall motion score index (WMSI) and left ventricular ejection fraction (LVEF) were obtained. Taking CAG as gold standard, the sensitivity, specificity and areas under the ROC curve (AUC) of definition of SCAS with GLS, WMSI and LVEF were calculated, respectively. Fifteen healthy volunteers were recruited as control. Results ①Definition of one or more branches with severe stenosis: The sensitivity and specificity was 77.51% and 100% with GLS of -17.50% as a cutoff value, 70.01% and 100% with WMSI of 1.00, and 57.51% and 100% with LVEF of 59.21%. ②Definition of two or more than two branches with severe stenosis: The sensitivity and specificity was 62.52% and 80.81% with GLS of -11.05% as a cutoff value, 56.22% and 65.31% with WMSI of 1.60 and 56.21% and 65.42% with LVEF of 54.31%. ③The correlation coefficient was 0.78 between GLS and LVEF, and -0.82 between WMSI and LVEF. The AUC of detecting one or more branch with severe stenosis with GLS, WMIS and LVEF was 0.87, 0.80 and 0.78, respectively, and AUC of GLS was more than that of LVEF (P<0.01). AUC of detecting two or more than two branches with severe stenosis with GLS, WMIS and LVEF was 0.76, 0.64 and 0.64, AUC of GLS was more than that of LVEF and WMSI (all P<0.01). Conclusion GLS can be used in detecting SCAS, and the value of GLS is better than that of WMIS and LVEF.

To explore the anti-tumor effect of immunotherapy with recombinant protein vaccine based on FGFR-1 of chicken (cFR-1) in a mouse Meth A fibrosarcoma model, tumor volume and survival rate of the mice were observed at a 3-day interval. Microvessel density (MVD) was detected by immunohistochemistry. Auto-antibodies against self-FGFR-1 were detected by Western blotting and ELISA, respectively. The anti-FGFR-1 antibody-producing B cells (APBCs) were detected by enzyme-linked immunospot (ELISPOT) assay. Eighteen days after inoculation of tumor cells, the tumor volume was significantly smaller in cFR-1-immunized group than in mouse FGFR-1 (mFR-1) immunized group and normal saline (NS) control group (P<0.05), and the survival time was significantly longer in cFR-1-immunized group than in the control groups (P<0.01). MVD was significantly lower in cFR-1-immunized group than in mFR-1-immunized group and NS group (16.8+/-5.6 vs 64.6+/-1.8 and 59.6+/-8.7, P<0.01). Antibodies against self-FGFR-1 were found in mFR-1-immunized group, the major antibody subclasses were IgG1 and IgG2b. Compared with the two control groups, the numbers of APBCs in cFR-1-immunized group were significantly increased (P<0.01) These results demonstrated that the cFR-1-related anti-angiogenesis protein vaccine could induce the production of auto-antibodies against self-FGFR-1, which futher inhibit angiogenesis and growth of solid tumor.

Objective To study the effect of gonadotropin releasing hormone agonist(GnRHa)against car-boplation-induced gonadotoxicity in rats. Methods Forty Wistar rats were divided into four groups which received carboplation, GnRHa + carboplation, GnRHa and normal saline respectively(n=10 for each group). Blood samples were collected from the abdominal aorta and the levels of blood follicle stimulation hormone (FSH) and estradiol (E<2>) were determined. Both ovaries and uterus of each rat were removed to measure the amount and the maturity of follicles. Body mass and morphological and pathological features of the rats were also observed. Results Compared with that in control group, the body mass of ovary and uterus decreased (P<0.05), and a significant reduction was observed in the number of ovarian follicles at each grade (P<0.05). The levels of E2 significantly lowered (P<0.05) and the level of FSH markedly ascended in group carboplation. Compared with that in group carboplation, the amount of primitive follicles significantly increased in group GnRHa + carboplation (P<0.05), and carboplation showed markedly protective effect on the ovarian and uterine morphological construction of rats. Conclusion Gn-Rha, appliying to preventing the rat reproduction damage in advance, has the certain protective function.

BACKGROUND: Lung protective ventilation strategies and positive endexpiratory pressure (PEEP) have been widely used as an effective ventilation pattern in clinical practice of administration of acute respiratory distress syndrome (ARDS) in recent years, but there arestill great arguments on the therapeutic effects.OBJECTIVE: To observe the changes of oxygenation index and inflammatory transmitters in peripheral blood and bronchoalveolar lavage fluid(BALF) of different lung areas [superior area of lung (upper lobe), ventral side of inferior lung (heart lobe), and dorsalis inferior lung (diaphragm lobe)] of ARDS dogs caused by pulmonary and extrapulmonary insults under lung protective ventilation treatment.DESIGN: A randomized control animal study.SETTING: Department of Respiratory Medicine, the General Hospital of Chinese PLA.MATERIALS: Twenty-four adult healthy male mongrel dogs were randomly divided into four groups with 6 dogs in each: pulmonary ARDS experimental group, pulmonary ARDS control group, extrapulmonary ARDS experimental group and extrapulmonary ARDS control group.METHODS: Models of extrapulmonary ARDS were induced by intravenous injection of oleic acid (0.1-0.15 mg/kg), and the pulmonary ARDS models were established by intratracheal administration of diocty sulfosuccinate sodium salt. After lung injury, the experimental groups received lung protective ventilation treatment (tidal volume: 8 mL/kg, PEEP: 0.981 kPa)for 3 hours, and the control groups also received ventilation of large tidal volume (tidal volume: 14-17 mL/kg, PEEP: 0 kPa).MAIN OUTCOME MEASURES: ① changes of oxygenation index in each group; ② dynamically observed the changes of the inflammatory transmitters [tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL1β) and interleukin-6 (IL-6)] in pe. Ripheral blood and BALF of different lung areas (upper lobe, heart lobe and diaphragm lobe) of ARDS dogs under lung protective ventilation treatment.RESULTS: All the 24 dogs were involved in the analysis of results. ①After lung injury, the oxygenation indexes were significantly decreased in all the groups, and the oxygenation indexes after lung protective ventilation in the experimental groups were obviously higher than those in the control groups (P < 0.05). At 2 and 3 hours after lung protective ventilation, the oxygenation indexes in the extrapulmonary ARDS experimental group were markedly higher than those in the pulmonary ARDS experimental group (P< 0.05). ② After lung injury, the levels of the inflammatory transmitters in peripheral blood were all obviously increased in all the groups, which were decreased to different extent after the lung protective ventilation treatment,but the therapeutic effect in the pulmonary ARDS experimental group was not as good as that in the extrapulmonary ARDS experimental group. ③The levels of inflammatory transmitters in BALF of lung upper lobe and heart lobe were obviously higher in pulmonary ARDS dogs than in extrapulmonary ARDS dogs.CONCLUSION: The ameliorations of the release of inflammatory transmitters and oxygenation index at different areas are obviously different between ARDS dogs caused by pulmonary and extrapulmonary insults, and lung protective ventilation has good effect on extrapulmonary ARDS dogs,but has bad effect on pulmonary ARDS ones.
