OBJECTIVETo explore the delayed protection of exercise preconditioning from the relative myocardial ischemia-reperfusion injury.

METHODSThe experiment included the vivo experiment and the vitro experiment, 32 Wistar rats in each experiment were divided into 4 groups randomly: control group (CN), relative ischemia reperfusion group (IR), exercise preconditioning group (EP) and Exercise preconditioning + relative ischemia-reperfusion group (EI). We detected the third loading exercise time, the levels of MDA in serum in vivo experiment and the Cardiac function parameter, the levels of MDA in coronary effluent in vitro experiment.

RESULTS(1) The vivo experiment: The third loading exercise time of EI group [(71.67 +/- 9.00) min] increased significantly compared with that of IR group [(58.67 +/- 4.13) min] (P < 0.05); The levels of MDA in serum of EP group (107.00 +/- 35.99) micromol/L and EI group [(152.23 +/- 29.94) micromol/L] decreased significantly contrasted to IR group (313.20 +/- 43.40 micromol/L) (P < 0.05). (2) The vitro experiment: The PRP (heart rate * left ventricular developed pressure) in reperfusion period of CN group and EP group were stable relatively, while it reached the peak after 30 minutes and almost recovered to the level before ischemia in EI group. The parameter of IR group recovered slightly but was lower significantly than that before ischemia. There was significant difference between the recovery rate of Cardiac function of EI group and that of IR group. The increase of MDA in coronary effluent after Ischemia-reperfusion of EP group (0.34 +/- 0.24 micromol/L) and EI group [(0.41 +/- 0.26) micromol/L] decreased significantly contrasted to that of IR group [(1.27 +/- 0.52) micromol/L] (P < 0.05).

CONCLUSIONEP has the obvious delayed protection from the relative myocardial ischemia-reperfusion injury.

ObjectiveTo observe the effect of dressing and moxibustion-pretreatment on the local joint swelling and stress hormone in hypothalami of rats with adjuvant arthritis (AA) at early and secondary stages.MethodsForty Wistar rats were randomly divided into 5 groups: normal group, early and secondary model groups, early and secondary pre-dressing and moxibustion (PDM) groups. The dressing with Chinese herb and moxibustion was stuck on Dazhui point (GV14) before the AA model established. The effects of dressing and moxibustion-pretreatment on the feet swelling and corticotropin-releasing-hormone (CRH), beta-endorphin (β-EP) and neuropeptide-Y (NPY) in hypothalami were observed.ResultsThe right feet swelling rate at early and secondary stages obviously increased after modeling ( P<0.01), and it became lower in early and secondary PDM groups than in model groups at the same phases ( P<0.05～0.01). The level of hypothalamic CRH was higher after modeling ( P<0.05～0.01), compared with early model group, it had a tendency to going down in early PDM group, moreover, in secondary PDM group the level was similar with the normal group. The level of hypothalamic β-EP increased significantly in early model group ( P<0.01), and lightly changed in secondary model group, it decreased in early PDM group but increased in secondary PDM group, compared with model groups at the same stages ( P<0.05). The level of hypothalamic NPY increased significantly after modeling, and it declined in the secondary PDM group ( P<0.05).ConclusionDressing and moxibustion-pretreatment can relief feet swelling of AA rats, which may be related with its regulative effect on the level of hypothalamic CRH, β-EP and NPY.

OBJECTIVETo explore Mechanisms of electroacupuncture in anti-inflammation and immunoregulation, and to compare differences among "Dazhui" (GV 14), "Mingmen "(GV 4) and non-acupoint in these actions.

METHODSAdjuvant arthritis rat model was made. The rats were divided into 5 groups: normal group, model group, "Dazhui" (GV 14) electroacupuncture group, "Mingmen" (GV 4) electroacupuncture group and non-acupoint electroacupuncture group. Effects of electroacupuncture on local joint inflammation and corticotropin-releasing hormone (CRH), beta-endorphin (betaEP) and interleukin-2 (IL-2) contents in the hypothalamus were observed and differences of the actions among different points were compared.

RESULTSCRH content in the hypothalamus in the "Dazhui" (GV 14) electroacupuncture group decreased as compared with the model group (P < 0.05); there was no significant change in beta-EP and IL-2 contents of the hypothalamus in the 3 electroacupuncture groups as compared with the model group (P > 0.05); there was positive correlation between CRH and IL-2 contents, and between IL-2 and beta-EP contents in the hypothalamus. The swelling rate of the toe in the "Dazhui" (GV 14) group and the "Mingmen" (GV 4) group was lower than that in the non-acupoint group (P < 0 05).

CONCLUSIONElectroacupuncture exerts anti-inflammation and immunoregulation possibly via regulation of CRH, IL-2 and beta-EP each other, and the anti-inflammation action of "Dazhui" (GV 14) and "Mingmen" (GV 4) is stronger than that of non-acupoint.

Objective To discuss the role of FAT2 gene in the ovarian epithelial carcinoma (OEC) and predict and analyze the possible mechanism and clinical value of FAT2 in the occurrence and development of ovarian cancer. Methods Data of 311 patients with OEC in the TCGA database were analyzed by cbioprotal online analysis platform. Kaplan-Meier method was used to analyze the relationship between the FAT2 genetic alteration and ovarian cancer survival. The FAT2 gene related proteins, protein network and enrichment analysis were performed by GeneCards database. Results In 311 patients, mutation of FAT2 gene was found in 12 patients with a mutation rate of 4%, amplification in 7 cases (2.3%), multiple mutations in 3 cases (1%) and deletion in 2 cases (0.6%). Kaplan-Meier curve showed that the total survival of patients with FAT2 genetic alteration was significantly longer than that in patients without FAT2 genetic alteration (P=0.0338). There was no significant difference in the disease-free survival time between the two groups (P=0.387). Twenty-one FAT2 related protein, such as CTNNB1, ARVCF and CTNND1 were down expressed in OEC tissues. The FAT2 related protein enrichment was analyzed, and Wnt signaling pathway, cell-cell adhesion and other cell physiological activities were found. Conclusion FAT2 may play the role in cancer suppressor gene in OEC, which induces the degradation of key protein CTNNB1 in Wnt pathway. The Over expression of FAT2 might be a good prognostic factor in ovarian cancer and can be used as a potential prognostic marker and a therapeutic target.

OBJECTIVETo study the protective effect of volatile anesthetics, isoflurane and sevoflurane, on ischemic neurons after cerebral ischemia-reperfusion in rats and its possible molecular mechanism.

METHODSRat cerebral ischemia-reperfusion model was developed by occlusion of the middle cerebral artery (MCA) and bilateral common carotid arteries (CCAs) 1 h after reperfusion. Using flow cytometry (FCM) and Northern blot hybridization, we calculated the number of apoptotic bodies and detected the expression of bcl-2 mRNA and interleukin-1beta converting enzyme (ICE) mRNA.

RESULTSThe apoptotic bodies in hippocampus analyzed by FCM peaked at appeared 24 h after reperfusion, and decreased about 54% and 40%, respectively, after treatment with isoflurane and sevoflurane, as compared with ischemic group. There was no significant difference in the expression of bcl-2 mRNA and ICE mRNA between the inhaled anesthetic groups and ischemic group in hippocampus 24 h after MCA/CCAs occlusion.

CONCLUSIONIsoflurane and sevoflurane partially inhibit apoptosis but have no significant effect on the expression of bcl-2 and ICE genes.

OBJECTIVETo investigate the relationship of gut flora and gut-derived endotoxin with minimal hepatic encephalopathy (MHE).

METHODSPatients with hepatitis B virus-related liver cirrhosis (HBV-LC) were screened for MHE using the number connect test-A (NCT-A) and digital symbol test (DST) and divided into the following groups: HBV-LC with (+) MHE (n = 26) and HBV-liver cirrhosis without (-) MHE (n = 25); in addition, one healthy immediate family member of each patient in the HBV-LC + MHE group was enrolled as a control. Each participant provided fecal and blood samples. PCR amplification and 454 pyrosequencing were used to detect bacterial 16S rRNA in feces. Turbidimetric Limulus amebocyte lysate assay was used to detect level of endotoxin in serum. The significance of inter-group differences was assessed by one-way ANOVA or Student's t-test.

RESULTSThe three groups showed different distributions of gut flora. The differences in the microbial communities' members and distributions were related to disease or health status, but not to the patient's genetic makeup or diet. In particular, the HBV-LC + MHE patients showed significantly lower amounts of different bacterial species and abundance of these species than the other two (non-MHE) groups (P less than 0.05). The healthy control family members had a richer diversity of gut flora than their counterparts with HBV-LC + MHE (P less than 0.05). The HBV-LV + MHE patients also had higher serum levels of endotoxin.

CONCLUSIONDevelopment of minimal hepatic encephalopathy in patients with HBV-LC may be related to a gut flora disorder or higher levels of endotoxin in serum.

OBJECTIVETo study the early change of serum nitric oxide (NO) after acute heat exposure with trauma and the effect of NO on mean arterial pressure (MAP), thus to provide theoretical basis for studying the mechanism of NO effect in acute stress.

METHODSThe rabbit model of acute heat exposure combined with trauma was established. The animals were divided into four groups, including control, trauma, hyperthermia and hyperthermia combined with trauma. The levels of NO were measured at different time points: 0 h, 1 h, 2 h and MAP was monitored throughout the whole experiment.

RESULTSThe concentration of NO declined at first and then increased at 1 h or so after acute heat exposure and trauma. The levels of NO in hyperthermia with trauma group at 1 h, 2 h were (42.75 +/- 8.24), (59.54 +/- 9.05) micro mol/L respectively (P < 0.05), while those in control group were (56.63 +/- 3.79) and (55.22 +/- 7.15) micro mol/L, the difference at 1h between two groups was significant (P < 0.05). Under the circumstance of hyperthermia and trauma, the level of MAP declined to the lowest point at 60 - 70 min and then showed a transient rise, after that, the level declined rapidly.

CONCLUSIONSAt the early stage of acute heat exposure and trauma, the concentration of serum NO declined at first and then increased, and had certain relationship with the change of MAP.
