Objective To investigate the effect of persistent ST-segment elevation after successful direct percutanous coronary intervention (PCI) on the late phase of left ventricular (LV) systolic function in acute anterior wall myocardial infarction.Methods Serial electrocardiograms were record before PCI and 1 hour after reperfusion in 72 patients with acute anterior wall myocardial infarction. The reduction of ST-segment elevation after successful PCI more than 50% was defined as ST-segment resolution (ST reduction group). Persistent ST-segment elevation was defined as ≥50% of peak ST elevation (ST elevation group). Echocardiography was performed on 2 to 3 weeks (early phase) and 5 to 6 months(late phase)after PCI to evaluate the LV function and ventricular wall motion abnormality (VWMA). Results Fifty-three patients (74%) had early ST segment elevation resolution and 19 patients (26%) did not. The LV function and VWMA were similar in two groups during early phase. But during the late phase, ST elevation group patients had lower LVEF and higher LVEDVI, LVESVI, VWMA index compared with ST reduction group (P

In this study, the embryological characters of Pterocypsela formosana (Asteraceae) were investigated with the traditional paraffin section methods. The anther has 4 sporangiates, the anther wall development follows the dicotyledonous type and comprises of an epidermis, endothelium, a middle layer and a single-layered tapetum, the tapetum belongs to glandular type. Meiosis of the microspore mother cells is of the simultaneous type, for the formation of mostly tetrahedral tetrad, the mature pollen grains are 2 celled. The ovary is bicarpellate, unilocular, one ovule and basal placenta, the ovule is unitegmic, tenuinucellate, inverted campylotropous and with developed endothelium, archesporial cell of megaspore differentiates immediately below the nucellar epidermis and functions as megasporocyte after development and belongs to tenuinucellate ovule type. The megasporocyte undergoes meitotic to form a liner tetrad, only one chalazal megaspore becomes the functional megaspore which forms female gametophyte including 7-celled and 8-nucleated after three successive mitosis, the female gametophyte is of the Polygonum type. Two polar nuclei melt into a secondary nuclei before fertilization, the chalazal antipodal cells are ephemeral and degenerate shortly after forming. Fertilization is porogamous and belongs to premitotic type of syngamy. The division of the primary endosperm nucleus is earlier than the zygote, the endosperm is of the nuclear type with the presence of haustoria, and the embryogeny belongs to asterad type chicory variant. The developed suspensor on early stage has important significance to the embryo development.

Aim To amplify P30 gene and express P30 fusion with GST Methods P30 gene was smplified from T. gondii chromosomal DNA and ligated to pGEM-T and pGEX-4T-1. Screening-positive recombinants were induced for expression, which was subsequently detected by WB Results P30 gene was amplified and GST-fusion was confirmed by rabbit antiT. gondii serum. Conclusions The construction of pGEM-T-P30 and pGEX-4T-1-P30, together with the recombinant protein would lay a base for further investigation of P30 at a molecule-level and application to diagnosis and vaccination

Objective To investigate the distribution modes of NOS nerves and interstitial cells of Cajal (ICCs) in myenteric plexus of human fetal intestine. Methods Small intestine samples from 12 fetuses were collected for the preparation of whole mount preparations and cryo sections examined by immunocytochemistry for c kit receptor tyrosine kinase and histochemistry for NADPH diaphorase. Results ICCs associated with the myenteric plexus in the fetal small intestine were observed in the shape of spindle or ovoid with two to three slender processes forming an independent and complete cellular network. While NOS positive nerves, which constitute the main neuronal component of ganglia, connecting strands, and nerve fibers, were found within the circular muscle layer and myenteric plexus of the small intestine and the latter was especially rich of this kind of nerves. Most of these positive neurons were Dogiel I type neurons and they often gathered in cluster in the ganglia. Each ganglion contained several to dozens of NOS positive neurons. Although no colocalization of ICCs and NOS positive nerves was found by double staining of whole mount preparations and cryo sections, they were closely distributed. Conclusion Our results indicate that NO released by myenteric plexus, an inhibitory neurotransmitter, may possess the function of regulating ICCs and smooth muscle in late stage of the fetus.

Objective To observe the curative effect of pricking bloodletting combined with acupuncture on patients with piriformis injury syndrome.Methods A prospective randomized controlled clinical trial was conducted, 84 patients with piriformis injury syndrome admitted to the Department of Acupuncture and Massage in the First Affiliated Hospital of Xinjiang Medical University from May 2011 to May 2014 were enrolled, and they were divided into observation group and control group by random number table, each group being 42 cases. The patients in the observation group were treated with bloodletting once a week (after bloodletting no other treatment was given), and then once a day of acupuncture was performed for 4 days in a week, completing one therapeutic course; while in the control group, the patient was treated with routine acupuncture once a day for 5 days in a week, finishing one therapeutic course. The interval between two therapeutic courses was 2 days, two courses were carried out, and afterwards the clinical therapeutic effects were evaluated in the two groups. The changes of visual analogue scale (VAS) of two groups before and after treatment and the therapeutic effects were observed.Results The VAS score of the two groups after treatment was lower than that before treatment, and the degree of decrease of VAS score in the observation group was significantly lower than that of thecontrol group (1.50±1.35 vs. 2.69±1.68,P < 0.01); the total effective rate in the observation group was obviously higher than that in the control group [100.00% (42/42) vs. 69.05% (29/42),P < 0.01].Conclusion Pricking bloodletting combined with acupuncture therapy for treatment of piriformis injury syndrome can shorten the course of treatment.

Evidence has indicated that low doses of anti-tumor regimens can induce cell apoptosis in vitro, although different regimens induce apoptosis by different mechanism and pathway. In recent years, new tumor treatment strategy has been mainly focused on inducing tumor cell apoptosis. The present review discusses the advantages and disadvantages of inducing tumor cell apoptosis. The benefit of inducing apoptosis is not to cause inflammatory reaction, but as its disadvantage, it inhibits immune responses, and the phagocytosis of apopotic bodies may result in horizontal transfer of genes (including oncogenes and other oncogenic materials), which can be one of the causes of tumor relapse. This paper proposes that the tumor treatment strategy should be turn into promoting tumor cell necrosis and inducing anti-tumor immune responses.
