Objective To compare the risk effects of different antiplatelet therapies on gastrointestinal injury and summarize the endoscopic characteristics of gastrointestinal mucosal injury in the elderly. Methods The dyspepsia symptoms, gastrointestinal bleeding and endoscopic findings were retrospectively evaluated among 577 patients who received the antiplatelet therapy with aspirin and/or clopidogrel. Results The risk of dyspepsia symptoms and gastrointestinal bleeding was slightly higher in clopidogrel group than in aspirin group (both P＞0.05, x2=0.48, 0.72), and OR (95% CI): 1.10 (0.59-2.07) and 1.74 (0.48-6.33), for the risk of dyspepsia symptoms and gastrointestinal bleeding, respectively. In aspirin plus clopidogrel group, the risk of dyspepsia symptoms had no significant increase as compared with aspirin or clopidogrel group (x2=0.37, 0.03, for aspirin or clopidogrel group, respectively, both P＞0.05), but the risk of gastrointestinal bleeding was significantly higher than in aspirin group (x2=5.43, P＜0.05), OR (95% CI): 4.77 (1.15-19.79) and slightly higher than in clopidogrel group (P＞0.05). In this study, 57 patients received endoscopy and the detection rate of erosion or ulcer was 78.9%. Erosion (61.4%) was most in the gastric antrum; gastric ulcer (10.6%) located in gastric antrum and angle; duodenal ulcer (18.0%) located in bulb. In patients with dyspepsia symptoms erosion (70.5%), were most likely found but patients with gastrointestinal bleeding showed mainly ulcer (69.2%). Conclusions In the elderly the use of clopidogrel alone is not safer than low-dose aspirin and the combination would increase the risk of gastrointestinal bleeding. The detection rate of erosion or ulcer is high in patients with symptoms. Patients with dyspepsia symptoms most likely show erosion, but patients with gastrointestinal bleeding have mainly ulcer and complex ulcers more common.

Objective To study the mechanism of respiratory tracts inflammation induced by the particles with an aerodynamic diameter of less than 10 ?m (PM10) and to observe the effect of high exposed group. Methods Particles were collected at kitchen, smoking-room, roadside and lake-side (the control group). Suspension of PM10 and rat models treated with PM10, kitchen oil smoke, cigarette smoke, road dust were established with a control group. On 22th day, the counts of total leukocyte and neutrophils in bronchoalveolar lavage fluid (BALF) and superoxide dismutase (SOD), glutathion peroxidase (GSH-Px), malondiadehyde (MDA), Cytokin-induced neutrophil chemotactics (CINC) in lung homogenate were measured and histopathological examinations were conducted on lung tissues. Results The counts of total leukocyte, macrophage and neutrophils in PM10-treat groups and the count of eosinophilia in road dust group increased significantly than those in control group (P

Objective To study Evaluation of serum soluble ST2 protein and brain natriuretic peptide(NT-proBNP)in patients with acute heart failure and prognosis of patients with acute heart failure.Methods Fifty cases patients with acute heart failure from April 2014 to April 2015 in the First Hospital of Traditional Chinese and Western Medicine of Beijing were researched.Detection of all patients with serum ST2,NT-proBNP,50 patients with acute heart failure were divided into heart failure group,50 healthy persons were selected as the control group.The control group and the observation group general heart failure data,the observation group and the control group of cardiac biomarker blood level,cardiac function level NT-proBNP blood concentration level,classification of cardiac function between ST2 blood concentration level were compared.Results Cr,BUN of heart failure group were higher than the control group,there was no significant difference between other indicators(P＞0.05).ST2((0.46±0.07)ng/L)in heart failure group was lower than the control group((0.66±0.20)ng/L),NT-proBNP((4160.20±57.49)ng/L)was higher than the control group((58.97±4.39)ng/L),heart function IV NT-proBNP blood concentration of the highest(9 428.29±75.93)ng/L,followed by grade III(1 921.01±30.27)ng/L,the second lowest(321.02±16.80)ng/L,(P＜0.01).Heart function IV level ST2 blood concentration was the highest(1.95±0.69)ng/L,followed by grade III(1.27±0.61)ng/L,class II minimum(0.78±0.24)ng/L(P＜0.01).Conclusion The serum ST2 and NT-proBNP are used to detect the patients with acute heart failure,can provide accurate diagnosis basis,has a very important value judgment on the classification and prognosis.

OBJECTIVE:To study the feature of fungus infection and the drug susceptibility for the fungus in our hospital.METHODS:Fungi were cultured and isolated by routine procedure and identified by VITEK microbe automatic system.Drug susceptibility test was performed using Rosco paper disk diffusion and broth dilution method with NCCLS M27-A.RESULTS:519 strains of fungi were all Blastocystis,with Monilia albicans making up 70.3%.Mycostatin showed the highest susceptibility,followed by amphotericin B.Fluconazol and itraconazole showed poor susceptibility.CONCLUSION:The resistant strains to common antifungal drugs experienced an obvious increase in clinical practice;therefore,it is imperative to monitor the drug susceptibility of fungi.

Venous valve plays an important role in regulating the venous flow,especially in preventing the blood backflow.It has heen observed that when deep vein thrombosis and dissolved,the valves in the lesions had been destroied or dysfunction.The mechanism of damage of vein valve has not been fully clarified,but as we know,it's common that the inflammatory reaction,due to many unfavorable factors,can cause thrombosis.On the other hand,deep vein thrombosis could bring out the inflammatory reaction as well.So the author will review the development of researching of the destruction of venous valves in recent years.

Objective To explore the recurrence-prevention effect of oral contraceptive and levonorgestrel-releasing intrauterine system (Mirena) after hysteroscopic endometrial polypectomy.Methods One hundred and seventy-four patients who received hysteroscopic endometrial polypectomy were enrolled in this research.The patients were informed and divided into three groups according to their selection:51 cases were given oral contraceptive since one month until 12 months after the surgery (oral contraceptive group); 60 cases were received Mirena since one month after the surgery (Mirena group) ; and 64 cases were received no treatment after the surgery (control group).The groups were followed up at 3,6,12 months after the surgery and compared the recurrence rate,menstruation,level of hemoglobin and complication rate.Results The recurrence rate in oral contraceptive group,Mirena group and control group was 3.9％(2/51),3.3％ (2/60) and 19.0％ (12/63),respectively.The recurrence rate in control group was higher than that in oral contraceptive group and Mirena group,and there was significant difference (P ＜ 0.05).The proportion of low menstruation volume in control group was lower than that in oral contraceptive group and Mirena group,and there was significant difference (P ＜ 0.05).The level of hemoglobin in control group was lower than that in oral contraceptive group and Mirena group [(124.55 ±9.33) g/L vs.(133.71 ± 11.03),(135.89 ±6.88) g/L],and there was significant difference (P ＜ 0.05).The incidence of complication in Mirena group [18.3％ (11/60)] was less than that in oral contraceptive group[35.3％(18/51)],and there was significant difference (P ＜ 0.05).Conclusions Oral contraceptive and Mirena after hysteroscopy for endometrial polys significantly decrease the recurrence rate.The complication rate of Mirena is lower and it is a safe and effective way to treat and prevent the endometrial polyp.
