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 observe the effect of continuous blood purification ( CBP ) in treatment of patients with severe viral encephalitis (SVE) combined with status epilepticus (SE).Methods Twenty-four SVE patients combined with SE were collected.Of which 15 cases received conventional treatment was control group, while 9 cases received CBP on the basis of conventional therapy was treatment group.The two groups were observed for curative effects.Results Compared with the control group, the remission time of fever, consciousness recovery, status epilepticus and mechanical ventilation were significantly shortened in treatment group ( all P<0.05 ) .The curative effects between the two groups were no significantly different.Conclusion For SVE patients with SE, the CBP treatment combined with conventional treatment can quickly relieve symptoms and improve the prognosis.

Objective To study the effects and mechanism of evodiamine on human colon cancer cell. Methods After human colon cancer SW620 cell were treated with different doses of evodiamine, the growth of anchorage independence of cancer cell was studied by colony formation in soft agar, and invasion ability was determined by Boyden chamber,and the level of mRNA and protein of midkine gene was detected by real time RT-PCR and Western blot assay, respectively. Results Ecodiamine could significantly inhibit both invasion ability and anchorage independence growth in dose-dependent manners. The level of mRNA and pro-tein of midkine of cancer cells treated with evodiamine reduced in time-and dose-dependent manners Conclusion Evodiamine could inhibit invasion of colon carcinoma cell through down-regulating of midkine expression.

Gefitinib and erlotinib play important roles, which as the representative of the epidermal growth factor receptor tyrosine kinase inhibitors for non-small cell lung cancer (NSCLC).However, preclinical and clinical studies find that many patients exist primary or acquired drug resistance to this drug, which limits the use of molecular targeted therapy drugs.At present, there are many studies focus on delaying or reversing drug resistance and developing new targets, which provide more potential for the molecular targeted therapy of NSCIC.

OBJECTIVETo investigate whether the genistein can increase the radiosensitizing effect on laryngeal squamous carcinoma Hep-2 cells.METHODS Hep-2 cells were treated with genistein, radiation, and genistein plus radiation respectively. DMSO was used as the control group. EdU assay was performed to assess the short-term effect of genistein and (or) radiation on the proliferation of Hep-2 cells. Clonegenic assay was used to detect the survival rate of Hep-2 cells after treatment with radiation doses of 0, 2, 4, 6, 8 Gy and radiation combined with genistein. The data was fitted into the classic single-hit multi-target mathematical model to analyze the long-term effect on cell proliferation death of Hep-2 cells.RESULTSIt was observed that radiation combined with genistein could significantly inhibit the proliferation of Hep-2 cells. And the SER of 10μmol/L genistein was 1.412.CONCLUTIONGenistein can inhibit the proliferation of Hep-2 cells by DNA synthesis inhibition, and can be an adjunct agent of radiotherapy.

Objective:To observe the difference of results of treadmill exercise test (TET) between male smokers and non-smokers .Methods:A total of 200 men with long-term smoking ≥20 cigarette per day were screened from outpatients and treated as smoking group .Another 200 men with similar age ,who didn’ t smoke at all ,were regarded as non-smoking control group (control group) .There were no medical history for hypertension ,hyperlipidemia ,diabetes ,and were nega-tive for electrocardiography and color echocardiography (exclude left ventricular hypertrophy etc .organic heart disease) in two groups .TET results and incidence rate of acute myocardial infarction (AMI) within two years were compared between two groups .Results:Compared with control group ,there were significant rise in TET positive rate (37. 5% vs .57. 5% , P<0.001) and incidence rate of AMI (8.5% vs .17.5% ,P=0.007) within two years in smoking group .Conclusion:Risk of suffering from coronary artery disease is more high in smokers among men .
