Objective:To investigate the use of proton pump inhibitors ( PPIs) in the patients with cirrhosis or hepatitis in one hospital and evaluate the use rationality .Methods:A retrospective study was carried out on 211 patients with the diagnosis of hepatitis or cirrhosis in the infectious disease ward between 2013 and 2014 , and the use rationality of PPIs was evaluated .Results: A total of 211 cases were inspected, and among them, 192 ones were treated with PPIs (91%) with 62 ones treated with PPIs irrationally, which accounted for 29.3%of the total cases.The main irrational use of PPIs was long treatment course (24.5%), inadequate prophylaxis indications (5.7%) and purposeless use (2.6%).Conclusion: Irrational use of PPI is common in hepatitis or cirrhosis patients . Clinical pharmacists should strengthen pharmaceutical care to improve the rational drug use .

Objective To investigate in knowledge rate of 120 first aid and satisfaction rate with emergency services among Nanchong citizens. Methods 360 patients who received prehospital first aid from three hospitals and their accompanies were selected from January to June 2010. The investigation content included knowledge rate of 120 first aid and satisfaction rate with emergency services. Results Results showed that about half of those surveyed still did not know the emergency phone"120" and its function, lacked self-help and self-protection knowledge, some respondents felt quite helpless upon daily life of electric shock, gas poisoning, coma and traumatic accidents. The attitude of the majority of emergency personnel was good or better, but still very stiff or irresponsible attitude existed in those few. This undermined the "120" and the image of credibility and emergency personnel. Conclusions There is an urgent need for universal coverage of on-site first aid knowledge and enhance awareness of first aid. Full-time staff in emergency department must pay close attention to the knowledge of first aid training, mastering the technique of bleeding control and bandaging, fixing, handling and CPR, as well as the use of instruments and equipment equipped in vehicles. Only in this way can we continuously improve the treatment of critically ill patients and increase survival rate.

Aim: To investigate the changes of endothelin( ET) receptors by isoproterenol in myocardial cells, and the invervention effects of CPU86017 and its RS isomer. Methods: Primary cultures of neonatal rat cardiomyo-cytes were prepared, and isoproterenol was added to each group for modeling, followed by drug interventions with propranolol, CPU86017 and RS chiral isomer respectively. Results: The expressions of ET_A and ET_B were increased by isoproterenol, in which the level of ET_B was higher than ET_A . This phenomenon was adjusted to different degrees by using propranolol, CPU86017 and RS chiral isomer in a dosage-relevant manner. The infervention effect of RS isomer was better than that of CPU86017 at the high dosage( 10 μmol/L). Conclusion: The cardiovascular effects of CPU86017 and RS chiral isomer could be correlative to the inhibition of the over-expressions of ET_A and ET_B.

ObjectiveTo compare the effects of two methods for the treatment of delayed defecation of neonatal meconium. Methods Sixty-seven neonates with delayed defecation of neonatal meconium were divided into experiment group (n=37) and control group (n=30). The former group was managed with abdominal massage followed by glycerol enema and the latter with abdominal massage followed by anus stimulation.Then the groups were compared in terms of the time for initial defecation of meconium,the volume of defecation,exhanstion time for defecation,abdominal distention and vomiting and serum bilirubin within 7 days.Result The treatment group was superior to the control one in terms of time for initial defecation of meconium,the volume of defecation, exhanstion time for defecation (P<0.05) and the incidences of abdominal distention,vomiting and serum bilirubin within 7 days were significantly lower than the control group (P<0.05).Conclusions The method of glycerol enema combined with abdominal massage is more effective for promoting defecation of neonatal meconium than the method of anus stimulation.It can reduce the incidence of abdominal distension,vomiting and pathological jaundice.

Objective To investigate whether arsenic trioxide(As2O3)with different density is capable of affecting the invasiveness of neuroblastoma(NB)cells,and to give grounds for NB therapy with As2O3.Methods 1.Well-developed NB cells were selected and exposed to 0.75 ?mol/L,1.50 ?mol/L,3.0 ?mol/L As2O3 for 24 h;2.Collect the adherence cells,count the number and float them in nutrient medium again,add them into the transwell polycarbonate membrane plate that was covered by matrigel,there were 2?104 NB cells in each well;3.After 24 h,take off the membrane,fix the cells which cross the membrane with mehanol and dye them with hematoxylin;4.Observe the NB cells and count them,so the capability of invasion of LA-N-5 was evaluated by transwell chamber assay.Results After 24 h with the different density As2O3,the number of invading LA-N-5 cells was significantly lower in As2O3 group than that in control group(the number of invading cells of the As2O3 group was 28.0?4.0,19.33?4.16,6.33?1.53,respectively,the cell number of the control group was 46.33?6.11)(P=0.013,0.003,0);among the experiment groups,there was no difference between 0.75 ?mol/L and 1.50 ?mol/L(P=0.06),and it was significantly different between 0.75 ?mol/L and 3.0 ?mol/L,1.50 ?mol/L and 3.0 ?mol/L(P=0,0.007),the number of invading LA-N-5 cells of 3.0 ?mol/L As2O3 was the least.Conclusions As2O3 could inhibit the invasive potential of NB cells;the inhibitory action of 3.0 ?mol/L As2O3 is the most.

Objective To compare the outcomes of powered-assisted septoplasty with CO_ 2 laser-assisted septoplasty. Methods Thitry patients with limited deviation of nasal septum were analyzed retrospectively. Among 30 patients, 18 underwent powered-assisted septoplasty and the rest underwent CO_ 2 laser-assisted septoplasty. The surgical results were assessed by the visual analogue scale (VSA) and acoustic rhinometry. Results VSA scores significantly improved in both groups after surgery (P

No significant differences were found among different age groups in RV systolic function parameters, whereas a trend of decrease in RV diastolic function was detected. Conclusion Echocardiography can be useful in assessing the structure and function of right heart quantitatively.

Objective To explore the reasons why patients with Keshan disesse complicated with hypertension and their interaction in Fuyu County, Heilongjiang Province. Methods Fifty-three patients with Keshan disease were investigated in January, April and July in 2007. Blood pressure was measured and the risk factors of hypertension were investigated. According to the diagnostic criteria of hypertension, patients were divided into hypertension group and non-hypertension group, and then the risk factors of hypertension, as well as the course of Keshan disease, were compared between the two groups. The risk factors include age, gender, family history of hypertension, salt intake in diet, smoking, drinking and obesity. Results The age of hypertension group[(57.83±8.89)years] was significantly higher than that of non-hypertension group [(51.53 ± 9.43)years, t = 2.3630, P < 0.05) ;while the course of Keshan disease in non-hypertension group [(31.63 ± 8.66)years] was notably longer than that in hypertension group [(25.08±11.41)years, t = 2.0224, P < 0.05] ;No statistically significant difference in gender, family history of hypertension, salt intake in diet, smoking, drinking and obesity was observed between the two groups(χ2 = 0.0072,0.1779,0.0029,0.1555,0.119,0.7679, all P > 0.05). Conclusions Age might be an important factor in patients with Keshan disease accompanied by hypertension, and the role of other risk factors of hypertension should not be overlooked;whether Keshan disease and hypertension can affect each other needs further investigation.
