Objective: To explore influence of urokinase on expression of soluble CD40 ligand (sCD40L) in patients with acute coronary syndrome (ACS).Methods: A total of 94 ACS patients diagnosed and treated in our hospital from Aug 2013 to Aug 2015 were selected.According to random number table, they were randomly and equally divided into routine treatment group and urokinase group (received small dose urokinase intravenous drip based on routine treatment group).Levels of sCD40L and cardiac troponin T (cTnT) before and after treatment, therapeutic effect and incidence rate of major adverse cardiovascular events (MACE) were measured and compared between two groups.Results: Compared with before treatment, there were significant reductions in levels of sCD40L and cTnT in both groups after treatment, P<0.01 all;compared with routine treatment group after treatment, there were significant reductions in levels of sCD40L [(2.92±0.36) ng/ml vs.(2.58±0.18) ng/ml] and cTnT [(0.10±0.02) μg/L vs.(0.04±0.01) μg/L] in urokinase group, P=0.013, 0.001 successively.Compared with routine treatment group, there was significant rise in total effective rate (76.6% vs.95.7%),and significant reduction in incidence rate of MACE (34.0% vs.4.3%) within six months in urokinase group (P<0.01 both).Conclusion: Urokinase can significantly inhibit expression of sCD40L and reduce release of cTnT, and improve therapeutic effect, and prevent major adverse cardiovascular events in patients with acute coronary syndrome.

Objective To assess the academic influence of research on blood pressure in the world and its frontiers. Methods Papers on blood pressure published from 2004 to 2008 and from 2009 to 2013 in China and foreign coun-tries were retrieved from Web of Science. Their academic influencing power was assessed and their evolution in the past 10 years was displayed by Citespace. Results The world outputs in research on blood pressure increased steadily from 2004 to 2014. The competitive force of the USA-led developed Western countries was strong and stable. The out-puts in research on blood pressure in China increased rapidly, but its influencing power was relatively low. Although progress was made at micro and macro levels,greater advances were achieved at gene,molecular and big data levels in the past 10 years. Conclusion The USA and European countries-led development in research on blood pressure is steady, and it is urgent for China to reduce its gap with USA and European countries.

Objective To know the distribution of arsenic and trace elements in drinking water in the endemic arsenism areas in Shanyin County, Shanxi Province. Methods Drinking water samples were collected from the chronic endemic arsenic poisoning areas of Silizhuang and Shanghexi, Shanyin County, Shanxi Province and HPLC-HG-AFS system was used to analyze the arsenic contents, valence and speciation. The trace elements were determined by ICP-MS. The data were analyzed by SPSS13.0 for windows. Results A total of 63 drinking water samples were determined, 39.68% of them exceeded the standard limit of arsenic level, inorganic arsenic was the main arsenical in drinking water, iAs3+/(iAs3++iAs5+) ratio was 56.17% in the water sample (arsenic was higher than 50 ?g/L) . The contents of Fe, Mn, Hg, Se and Pb in part of drinking water samples exceed the standard limits. No significant difference was seen between the arsenic results determined by HPLC-HG-AFS and ICP-MS. Conclusion Arsenic contamination of drinking water in Shanyin County, Shanxi Province is severe. The most frequently seen arsenic valence state in drinking water is iAs3+. Some trace elements in part of drinking water samples exceed the standard limits, this may aggravate arsenic poisoning.

OBJECTIVE To explore the latency characteristics of speech evoked auditory brainstem response(speech-ABR)from healthy Chinese adults by different stimulation intensities and its significance in neural encoding of speech in the brainstem. METHODS ABRs to speech syllables of 32 subjects were recorded in four stimulus intensities varied from 20 to 80 dB SPL by 20 dB steps, under 11.1/s stimulus rate. A set of featured waves were determined under these intensities, and then the characteristics of their latencies were analyzed. RESULTS A series of featured waves were observed starting from onset response(including V and A waves), transitional C wave, then following frequency-following responses(FFRs), and the offset O wave. As the reduction of stimulus intensity, the latencies of speech-ABR delayed significantly(P

OBJECTIVE:To investigate the effects of uterine arterial embolization combined with Methotrexate and Lactate ethacri-dine on related indexes of mid-pregnant patients with placenta previa abortion. METHODS:The data of 100 mid-pregnant patients with placenta previa who required inducing labor was retrospectively analyzed and divided into observation group(50 cases)and control group(50 cases)by different treatment. Control group received uterine arterial embolization before inducing labor,then received Lac-tate ethacridine injection 100 mg,amniotic injection+Mifepristone tablet 75 mg,and aborted after 2 d. Observation group received uterine arterial embolization after uterine arterial perfusionon both sides,then received Methotrexate for injection 50 mg/side after uter-ine arterial embolization catheter entering uterine artery,Lactate ethacridine injection(the same usage and dosage as control group)+Mifepristone tablet(the same usage and dosage as control group)was given after 12 h. Total parturition,intrapartum hemorrhage,hos-pitalization time,menstruation recovery time,cesarean section,hysterectomy,retained placenta and clearing palace in 2 groups were observed,and postoperative complications were recorded. RESULTS:Intrapartum hemorrhage,hospitalization time,cesarean section rate and hysterectomy rate in observation group were significantly lower than control group,with statistical significance(P<0.05), while there were no significant differences in total parturition,menstruation recovery time,retained placenta rate and clearing palace rate in 2 groups(P>0.05). There was no significant difference in the incidence of postoperative complications in 2 groups(P>0.05). CONCLUSIONS:Uterine arterial embolization combined with Methotrexate and Lactate ethacridine can effectively reduce the hemor-rhage of mid-pregnant patients with placenta previa abortion,shorten hospitalization time,and decrease cesarean section and hysterec-tomy rate.

Objective Postoperative cognitive dysfunction (POCD) is a common complication of cardiac surgery, which seriously affects the prognosis of the patient.This study aimed to explore the risk factors for early POCD in patients undergoing cardiac valve surgery and the correlation between early POCD and the serum S100B protein level.Methods Eighty patients underwent mitral valve replacement surgery in combination with tricuspid plasty.At 1 day before and 5 days after surgery, we assessed the cognitive function of the patients and divided them into a POCD and a non-POCD group.We obtained such data as the age, sex, education, New EuroSCORE Ⅱ, and preoperative NYHA cardiac function grades and left ventricle ejection fraction (LVEF) of the patients, collected the venous blood to determine serum S100B protein concentration by ELISA, and analyzed the independent risk factors of early POCD using single-factor and binary logistic regression analyses.Results POCD was found in 20 (25%) of the patients, , Logistic regression analysis showed the independent risk factors for early POCD to be hyperglycemia (OR=6.038, 95% CI: 1.202-30.337), operation time (OR=6.423, 95% CI: 1.276-32.332), and aspartate aminotransferase (AST, 2 times higher than normal) (OR=12.878, 95% CI: 2.289-72.445).The serum S100B protein concentrations in the POCD group were (1.9±0.3) μg/L and (1.7±0.4) μg/L at 48 and 72 hours after cardiopulmonary bypass, significantly lower than (2.4±0.4) μg/L and (2.1±0.3) μg/L at 30 minutes and 24 hours (P<0.05), and so was it in the non-POCD group at 72 than at 48 hours postoperatively ([1.4±0.4]) vs [1.5±0.4] μg/L, P<0.05).Conclusion Long operation time, perioperative hyperglycemia and high AST are independent predictors and the serum S100B protein level is a significant marker of early POCD.
