Aim To investigate the effect of osthole against thrombosis and platelet aggregation.Methods Rat model of artery-vein bypass thrombosis and mouse model of thrombosis by injecting collagen-adrenaline to the vein of the tail were used to measure the thrombus weight and to observe the number of dead mice in 5 min and the recovery mice from hemiplegia in 15 min. ADP,thrombin and arachidonic acid were used to induce platelet aggregation on human and the rate of platelet aggregation in 1,3 and 5 min and the maximum rate of platelet aggregation were detected.Results Osthole inhibited artery-vein bypass thrombosis and reduced thrombus weight in rats to defferent degrees,inhibited the thrombosis induced by collagen-adrenaline and reduced the death rate in 5 min and increased the recovery rate in 15 min. Osthole also inhibited human platelet aggregation induced by ADP,thrombin and arachidonic acid in vitro.The values of IC_(50 )(dose of the drug giving 50% inhibition) were 0.444 g?L~(-1) for ADP,0.186 g?L~(-1) for thrombin, 0.421 g?L~(-1) for arachidonic acid, respectively.Conclusion Osthole exert remarkable effects against thrombosis and platelet aggregation.

Objective To establish and evaluate the method for detection of methicillin-resistant Staphylococcus aureus (MRSA) by the cefoxitin disk diffusion test.Methods The disks with 30 microgramme of cefoxitin and oxacillin recommended by NCCLS were used for the detection of MRSA with PCR by using mecA as the reference.The MIC of cefoxitin to Staphylococcus aureus was also determined.Results Of the 145 test isolates of Staphylococcus aureus,83 isolates showed the mecA-positive by PCR,62 isolates were negative.In cefoxitin disk diffusion tests,82 isolates showed MRSA-positive and 63 isolates were negative.The sensitivity was 98.8% and the specificity was 100%.In oxacillin diffusion tests,the sensitivity was 95.2% and the specificity was 96.8%.Conclusions For the detection of MRSA,the cefoxitin disk diffusion test was consistent with the results by PCR for mecA.The cefoxitin disk diffusion test is easy to be performed and can be used in routine diagnostic works.

Objective To investigate the effects of Panax notoginseng saponins(PNS,三七总皂苷) on extra-vascular lung water(EVLW) and respiratory dynamics in dog with oleic acid induced acute lung injury(ALI).Methods Eighteen Beagle dogs,intubated and mechanically ventilated with intermittent positive pressure ventilation(IPPV) mode(tidal volume(VT) 10 ml/kg, positive end-expiratory pressure(PEEP) 0,inspiratory oxygen concentration(FiO2) 1.00),were randomly assigned into three groups(each n=6): normal control group,ALI model group(induced by intravenous injection of oleic acid) and PNS group(received PNS after the ALI model was constructed).PNS 10 mg/kg being dissolved in 100 ml 5% glucose solution(GS) was pumped into central vein (2.5 ml/min) after ALI model was formed in the PNS group.Similar amount of glucose solution was given to the normal control and model groups.Respiratory dynamics and arterial blood gas(ABG) were monitored every hour.Four hours after the establishment of ALI,the dogs were sacrificed and extra-vascular lung water index(EVLWI) was quantified by a gravimetric measurement.Results In ALI dogs,PNS significantly decreased the index of EVLWI((14.10?1.45) ml/kg vs.(17.97?0.85) ml/kg,P0.05).Conclusion PNS has certain protective effect on dog with oleic acid induced ALI,it may lower EVLW and elevate the Cst total,that is beneficial to the improvement of hypoxemia.

Objective: To explore the relationship between plasma levels of soluble receptor of advanced glycation end products (sRAGE), brain natriuretic peptide (BNP) and cardiac function in patients with sepsis.
Methods: A total of 83 sepsis patients treated in our hospital from 2014-01 to 2015-06 were studied. Plasma levels of sRAGE, BNP were examined at 24 h after admission and they were evaluated by APACHEII scores. According to BNP levels, the patients were divided into 2 groups:Normal cardiac function group, the patients with BNP<500 pg/ml, n=32 and Cardiac dysfunction group, the patients with BNP≥500 pg/ml, n=51. The cardiac function as stroke volume (SV), LVEF, minute volume, E/A were examined by echocardiography. The above indexes were analyzed and compared between 2 groups, the relationship between plasma levels of sRAGE and the occurrence of sepsis was assessed by Logistic regression analysis.
Results: Compared with Normal cardiac function group, the patients in Cardiac dysfunction group presented decreased SV, LVEF, minute volume and E/A;increased APACHEII scores and sRAGE, all P<0.01. Plasma levels of sRAGE in sepsis patients were positively related to BNP (r=0.90, P<0.05) and APACHEII scores (r=0.85, P<0.05). Logistic regression analysis indicated that plasma levels of sRAGE (OR=1.019, 95%CI 1.004-1.035, P<0.05) was independently related to cardiac function in patients with sepsis.
Conclusion: Plasma levels of sRAGE were independently related to cardiac function in patients with sepsis.

Objective To investigate the clinicopathologic characteristics of premalignant and malignant endometrial polyps (EP) in premenopausal and postmenopausal women.Methods A retrospective analysis was conducted in 42 cases of premalignant and malignant EP from 1993 to 2012.Polyps were classified into premenopausal (group A,10 cases) and menopausal (group B,32 cases),including 26 cases of endometrioid adenocarcinoma,4 of clear cell carcinoma,9 of serous adenocarcinoma,and 3 of atypical hyperplasia.Results The prevalence rate of premalignant and malignant EP was 1.42％ (42/2 965),the prevalence rate of malignancy in postmenopausal and postmenopausal women was 0.48％ (10/2 064) and 3.55％ (32/901),respectively.The mean size of EP was (1.6 ± 0.8) cm,abnormal uterine bleeding was positive in 90％ (38/42) of cases.The EP pathological diagnosis showed all were endometrioid adenocarcinoma in group A,while there were 4 of clear cell carcinoma,9 of serous adenocarcinoma in group B.The mean size of EP was (1.1 ± 0.6) and (1.7 ± 0.9) cm in group A and B respectively (P ＜0.05).According to immunohistochemistry,all cases of group A were ER positive,but 41％ (11/27) of group B were ER negative (P =0.059).The PR positive rate was 8/9 and 56％ (15/27) in group A and B,respectively (P =0.169).Conclusions The risk of the EP malignancy rate is higher,while ER,PR positive rate are lower in postmenopausal womcn.Postmenopausal EP,especially accompanied by abnormal uterine bleeding and large polyps should be removed as soon as possible.
