Objective To explore the real experience of patients with aortic dissection (AD) disease during the early phase of the disease. Methods Interpretation phenomenological analysis method was used in the study. Self- structured in- depth interviews were conducted with AD patients who were admitted to the hospital from November 2013 to February 2014, and combining the participation observation method to collect relevant data. Data were analyzed by content analysis. Results 16 cases were interviewed and four advanced themes were extracted: experience of disease symptoms; negative emotion; coping styles; the insight of life. Conclusions AD patients can produce complex psychological experiences when they are informed of the diagnosis because of the experience of pain, sudden critical illness, the role change and so on. Medical staff should pay attention to their psychological status and needs, take corresponding effective measures to promote the further treatment and their physical and psychological rehabilitation.

Objective To explore the changing regularity of humeral distal epiphysial anteverted angulation with ultrasonic measurement. Methods Using an ultrasonic diagnostic apparatus with a high frequency bougie to detect the dextral elbow joint of 203 normal individuals whose age range is from 5 d to 23 years old. The subjects were divided into 5 groups by age (5 d-4 years old, 5-8 years old, 9-12 years old, 13-16 years old, ≥17 years old),and by sex into two large parts.Anteverted angulation of capitellum and lateral semitrochlear ossification center were measured with statistic analysis and correlation calculation.Results Anteverted angulation of capitellum was 48.89?? 8.96?, lateral semitrochlea 33.70?? 7.18?. Anteverted angulation of capitellum enlarges with age growth, and it reaches the climax ( 55.00?? 5.88?) at the age 13-16 years old. There was a significant difference among groups. After 17 years old, anteverted angulation slightly reduces to 52.38?? 8.27?, compared with the climax ( 55.00?? 5.88?), there was no statistical difference. Changing regularity of anteverted angulation was similar to that of capitellum. Just between the 5 d-4 years old group and 5-8 years old group, the difference was significant in angulation enlargement. There was no statistical difference among the groups above the 5-8 years old group, and no significant difference between male and female in humeral distal epiphysial anteverted angulation. Conclusions Ultrasonic examination can clearly display the images of humeral distal epiphysis. Observation and measurement is available for the epiphysial anteverted angulation by acoustic images, and the changing regularity of anteverted angulation can be illustrated.

Objective To observe the clinical efficacy of recombinant human endostatin (endostar)combined with intravenous chemotherapy and intraperitoneal hyperthermic perfusion chemotherapy for advanced ovarian cancer (AOC).Methods Sixty-one patients with AOC were divided into treatment group (31 cases) and control group (30 cases) by table of random digit.The treatment group was given endostar +TP project (paclitaxel intravenous chemotherapy + cisplatin intraperitoneal hyperthermic perfusion chemotherapy).The control group was given endostar + TP project (paclitaxel and cisplatin intravenous chemotherapy).The recurrence rate,survival rate,improvement of quality of life (QOL) and drug side effects were observed in two groups.Results The improvement rate of QOL in treatment group was significantly higher than that in control group [64.5％(20/31) vs.33.3％(10/30),x2 =5.931,P=0.015].The 1-year and 2-year recurrence rate in treatment group were significantly lower than those in control group [17.2％(5/29)vs.41.4％(12/29),34.5％(10/29) vs.62.1％(18/29),P=0.043 and 0.036].The 1-year and 2-year survival rate in treatment group were significantly higher than those in control group [93.1％(27/29) vs.72.4％(21/29),79.3％ (23/29) vs.51.7％ (15/29),P =0.037 and 0.027].The incidence of nausea and vomiting in treatment group was significantly lower than that in control group [67.7％ (21/31) vs.93.3％ (28/30),P =0.012],there was no significant differences in bone marrow suppression,hair loss and liver and renal injury incidence between two groups (P ＞0.05).Conclusion Endostar combined with intravenous chemotherapy and intraperitoneal hyperthermic perfusion chemotherapy for AOC is safe and effective,and can improve patients' QOL,reduce the rate of recurrence and prolong survival time.

OBJECTIVE:To enrich the identification diversity of traditional Chinese medicine(TCM),and provide theoretical guidance for the quality evaluation of TCM. METHODS:According to literature references and traditional identification experienc-es,characteristics including medicinal shape,size,color and lustre,surface,texture,section,odor and other aspects were identi-fied by sense organs such as eyes,hands,nose and mouth. The vivid traditional identification term were obtained through systemat-ic summarization in order to explore the internal relationship with pharmaceutical botany. RESULTS&CONCLUSIONS:As the sim-plest identification method,traditional identification method can rapidly identify the species and quality of TCM,evaluate the quali-ty,and has great significance to solve the security issues of clinical medication and health care in daily life. There was a correlation between the traditional identification and botanical research,which could be able to provide theoretical guidance to characters identi-fication and quality evaluation of TCM.

Objective To investigate the effect of daurinoline on basilar artery vascular smooth muscle. Methods The tension of isolated basilar artery ring of rabbit was measured. The effects of daurinoline on the basilar artery contracted by methoxamine,5-hydroxytryptamine(5-HT),KCl and Histamine( His)were also examined. Dose-response curves of 5-HT and KCl were observed as well. Results Daurinoline exerted obvious relaxation effect on the basilar artery vascular ring contracted by methoxamine,5-HT,KCl and His in a concentration-dependent manner. IC50 of daurinoline in methoxamine,5-HT,KCl and His-treated rabbits was 8.67×10-5,1.78×10-6,6.79×10-7 and 4.98×10-4 mol·L-1,respectively. The change of concentration-response curves of methoxamine,5-HT,KCl and His showed that daurinoline was a non-competitive antagonist. Conclusion Daurinoline exerts marked relaxation effect on basilar artery of rabbits through non-competitive antagonism. The mechanism of relaxation action may be related to blockage of voltage-dependent or receptor-dependent calcium channels.

Objective To realize antimicrobial resistance and carrying status of OXA carbapenemase among imi-penem-resistant Acinetobacter baumannii (IRAB)isolated from patients of Hohhot,so as to provide guidance for the prevention and control of healthcare-associated infection(HAI)caused by multidrug-resistant Acinetobacter bauman-nii .Methods 49 IRAB isolates from 3 tertiary first-class hospitals in Hohhot between January and December 2012 were collected,antimicrobial susceptibility testing was performed by Kirby-Bauer disk diffusion method,four geno-types(blaOXA-51-like ,blaOXA-23-like ,blaOXA-24-like ,blaOXA-58-like )of OXA carbapenemase were detected by polymerase chain reaction (PCR).Results All 49 isolated IRAB strains were found to be highly resistant to antimicrobial agents (81 .63%-100.00%)except to minocycline (8.16%);blaOXA-51-like was identified in 49 strains (100.00%),42 (85.71 %)of which also carried blaOXA-23-like gene ,blaOXA-23-lik and blaOXA-51-like were both found in three hospital, blaOXA-24-like and blaOXA-58-like weren’t found.Conclusion IRAB strains present multidrug resistance,resistant to mi-nocycline is the lowest;blaOXA-23-like is the main drug-resistance mechanism of IRAB in Hohhot.

Objective:To evaluate the relationship between intestinal mucosal mast cells and intestinal flora during intestinal ischemia-reperfusion(I/R) in mice.Methods:Forty-eight healthy male C57BL/6 mice, aged 9-12 weeks, weighing 20-25 g, were divided into 4 groups ( n=12 each) using a random number table method: sham operation group (group Sham), sham operation plus mast cell membrane stabilizer cromolyn sodium (CS) group (group Sham+ CS), I/R group and I/R+ CS group.The intestinal I/R injury was induced by clamping the superior mesenteric artery for 45 min followed by 4 h of reperfusion in I/R and I/R+ CS groups.The superior mesenteric artery was only exposed but not occluded in Sham and Sham+ CS groups.CS 50 mg/kg was intraperitoneally injected once a day for two weeks before surgery in Sham+ CS and I/R+ CS groups.The equal volume of normal saline was intraperitoneally injected once a day for two weeks before surgery in Sham and I/R groups.Mice were then sacrificed and intestinal tissues were harvested for examination of the pathological changes of intestinal mucosa with a light microscope after HE staining, and the damage to intestinal tissues was assessed and scored according to Chiu.The expression of mast cell tryptase was detected using the immunohistochemical SP staining method, and the mast cells were counted.The intestinal contents were collected, the total amount of bacteria in intestinal flora was detected by 1% agarose gel electrophoresis, and the diversity (Chao1 index and Shannon index) and relative abundance of intestinal microbial bacteria were detected by 16S rDNA sequencing method. Results:Compared with Sham group, the Chiu′s score and mast cell count were significantly increased, the expression of mast cell tryptase was up-regulated, the total amount of intestinal flora bacteria was increased, Chao1 index and Shannon index were decreased, the relative abundance of Bacteroidetes, Proteobacteria, Bacteroides and Enterobacteriaceae were increased, and the relative abundance of Firmicutes, Lactobacillus and Bifidobacteria was reduced in I/R group ( P<0.05 or 0.01), and no significant change was found in the parameters mentioned above in Sham+ CS group ( P>0.05). Compared with I/R group, the Chiu′s score and mast cell count were significantly decreased, the expression of mast cell tryptase was down-regulated, the total amount of intestinal flora bacteria was decreased, Chao1 index and Shannon index were increased, the relative abundance of Bacteroidetes, Proteobacteria, Bacteroides and Enterobacteriaceae were reduced, and the relative abundance of Firmicutes, Lactobacillus and Bifidobacteria was increased in I/R+ CS group ( P<0.05 or 0.01). Conclusion:The activation of intestinal mucosal mast cell can lead to imbalance of intestinal flora, decrease the number of probiotics and increase the number of potential pathogenic bacteria, and thus be involved in the pathophysiological mechanism of intestinal I/R injury in mice.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of autoimmune diseases with rapid progession and poor prognosis.The histopathological hallmark in the kidneys of patients with AAV is " pauci-immune" necrotizing crescentic glomerulonephritis,therefore complement was previously suggested not to play a major role in the disease development.However,in the recent years,accumulating evidence from both experimental and clinic study has strongly incriminated alternative complement pathway activation as critically important in the pathogenesis of AAV.In patients with AAV,plasma levels of Bb and FH,components of the alternative complement pathway,are associated with disease activity and prognosis,which might be useful biomarkers in monitoring systemic disease activity and renal disease activity in AAV.The complement activation product C5a and its interaction with C5a receptor play a central role.It is suggested that neutrophils,ANCA and complement system form a positive feedback loop contributing to the development of AAV.Preliminary data of two clinical trials have demonstrated effectiveness and safety of C5a receptor blockade in patients with AAV.Therefore,measurement of complement biomarkers will be helpful in assessing the disease activity of patients and be of great importance for monitoring the efficiency of complement-targeting therapy in the future.
