Objective To discuss the effect of the modified structure of oxygen equipment on oxygen inhalation effect of patients receiving oxygen therapy.Methods The structure of oxygen equipment was modified.and 80 patients who required oxygen therapy were divided into the modified group and the non-modified group according to odd and even number of hospital admission sequence randomly with 40 patients in each group.The modified group used the modified oxygen equipment,the non-modified group used traditional one.The differences of respiration,heart rate and blood oxygen saturation rate between the two groups before oxygen inhalation,30 minutes and 2 hours after oxygen were compared.Results There was no significant difference in the respiration,heart rate and blood oxygen saturation rate between the two groups.Conclusions The modified oxygen equipment doesn't affect the oxygen therapy effect of patients,besides,it avoids the problems of pollution and the complicated disinfection procedure of the structure of the humidifier bottle,fluid and breathing vessel of the traditional equipment.

Objective: To evaluate the effectiveness in Group Interpersonal Psychotherapy by alleviating the symptoms and improving social function in depressive inpatients. Methods:60 inpatients meeting criteria of DSM-Ⅵ for Major Depression were randomly assigned to experimental group and control group, 30 cases each. The experimental group received integral intervention including antidepressants and Group Interpersonal Psychotherapy, while the control group received mono-therapy of antidepressants for 12 weeks. Interpersonal problem was identified before the therapy. HAMD, SDSS were administered at the end of screening day and 12 week to both group. Result:1.Interpersonal problems areas (grief, interpersonal disputes, role transition and interpersonal deficit) in depressive inpatients showed a significant difference (5%,55%,30%,10%,?~2=3.187,P

ObjectivesTo assess the cardiovascular function in obese children.MethodsA total of 30 obese children and 50 age- and sex-matched normal weight children were enrolled and treadmill test was performed. Exercise tolerance, the time to target heart rate and continuous T-wave alternans (TWA) during treadmill test were compared between two groups. ResultsCompared with normal weight children, the exercise tolerance was decreased and the time to target heart rate was shortened, while the incidence of continuous TWA was increased in obese children and there was signiifcant difference between two groups (P<0.01).ConclusionsObesity may lead to cardiovascular dysfunction in childhood which should be concerned.

Objective To investigate the mortality and cause of death in inpatients with cerebral infarction. Methods The clinical data of 515 patients with cerebral infarction as the underlying cause of death from January 2005 to December 2009 were analyzed retrospectively. The hospital mortality, direct cause of death,and constituent ratio of the cause of death were calculated. The clinical features,such as classification of the Trial of Org 10 172 in acute stroke treatment( TOAST),age and duration of hospital-ization were analyzed. Results ( 1 )The hospital mortalities in patients with cerebral infarction from 2005 to 2009 were 2. 0%(91/4 659),2. 1%(110/5 264),1. 9%(95/5 035),1. 2%(100/8 656),and 1. 0%(119/11 640),respectively. The overall mortality rate was 1. 5%(515/35 254),basically had a declining trend year by year(χ2 =42. 39;P<0. 01).(2)The mortalities of the inpatients with cerebral infarction in the young( <45 years),middle-aged(45 to 59 years),elderly(60 to 74 years),and aged ( >74 years)groups were 1. 1%( 22/2 009 ),1. 0%( 112/11 158 ),1. 5%( 221/14 311 ),and 2. 1%(160/7 776),respectively. They increased with increasing age(P<0. 01).(3)The TOAST classification in 515 died patients were as follows:57. 3%(n=295)for large-artery atherosclerosis,19. 4%(n=100) for cardioembolism,14. 4%(n=74)for cryptogenic stroke,7. 0%(n=36)for small-artery occlusion and 1. 9%(n=10)for other reasons. The five leading direct cause of death were cerebral hernia 49. 3%(n=254),primary central respiratory and circulatory failure 25.0%(n=129),pneumonia 8. 9%(n =46), cerebral-cardiac syndrome 5. 8%( n =30 ),and multiple organ failure 5. 6%( n =29 ).( 4 ) The mean age of death was 67 ± 12 years old. The patients who died of cerebral hernia and primary central respiratory and circulatory failure were younger than those who died of pneumonia(65 ± 13,68 ± 11,and 75 ± 10,respectively;all P<0. 01). The median length of hospital stay was 3 days. The length of hospital stay in patients who died of hernia,primary central respiratory and circulatory failure,and cerebral-cardiac syndrome were significantly shorter than those who died of pneumonia and multiple organ failure( the median length of hospital stay was 3. 0,3. 0,3. 0,12. 5,and 9. 0 days,respectively;all P <0. 05). Conclusions The mortality of hospitalized patients with cerebral infarction have a declining trend year by year. Brain disease itself is the most important reason of early death for patients with cerebral infarction, indicating that it is the important point of prevention and treatment in clinical work.

OBJECTIVE:To investigate the efficacy of compound azintamide enteric-coated tablet plus mosapride citrate dispersible tablet for abdominal distention in patients with functional dyspepsia(FD).METHODS:A total of 80 patients with the chief complaint of abdominal distention were randomized to treatment group(Group A,n=40) to be treated with mosapride citrate dispersed tablets plus compound azintamide enteric-coated tablet,or control group in which the patients were treated bu mosapride citrate dispersed tablets(Group B,n=20) or compound azintamide enteric-coated tablets(Group C,n=20).Comp-ound azintamide enteric-coated tablets were administered orally tid(2 tablets) immediately after meal while the mosapride citrate dispersed tablets(5mg) were administered orally tid 30min before meal for 2 weeks.The main outcome measures were changes of symptom scores of abdominal distension,the total effective rates in improvement of abdominal distension,and drug side effects before and after treatment.RESULTS:After 1-week and 2-week treatment,the average index scores of abdominal distention in the treatment group(Group A) were significantly lower than in the control groups(Group B and Group C) (P

Objective To explore the oxidative damage and genotoxicity of organic chemical pollutants from running water and the source water in Baotou reach of the Yellow River to mice. Methods The Kunming mice were treated with the organic extract solutions of the Yellow River water and running water by gavage at different concentration,once a day and the activity of the superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and the content of malondialdehyde (MDA) in the liver and kidney and the rate of micronucleus were determined. Results SOD and GSH-Px activity in the liver and kidney in the groups treated with the water of three sections of Yellow River in Baotou City decreased as the exposure dose increased. Except the low concentration group of running water,the MDA content in the liver and kidney and the micronucleus rate increased significantly compared with the control (P

Objective To investigate the causes,preventive measures and treatment of digestive tract injury during laparoscopic cholecystectomy (LC). Methods From January 2000 to December 2007,totally 21 640 patients underwent LC in our hospital,among them,16 had digestive tract injury including injuries in the stomach and duodenum in 14 patients,in the colon in 1,and in the ileum in 1. Results Among the 16 cases,13 were detected during the operation,and thus laparoscopic repair were performed on 3 of the cases,and conversion to open surgery were carried out for the other 10 for repair of the injured tract (7 cases) or major resection of the stomach and Roux-en-Y anastomosis (3 cases). The other 3 patients were confirmed after LC;they received open surgery for repair of the ileum,colostomy or intra-abdominal cavity drainage. In the 16 cases,one patient died of duodenal leakage complicated with multiple organ dysfunction syndrome in 7 days after the operation;the other 15 patients were cured and discharged from hospital without severe complications. Conclusions Most of the digestive tract injury cases during LC are caused by pericholecystic inflammatory adhesion,which leads to insufficient exposure of the surgical field resulting in the tear or perforation of the digestive tract. Proper treatment in early stage is the key to the prognosis of the patients and prevention of severe complications.

OBJECTIVE:To compare the effects of different doses of ramipril on blood pressure and renal function of early di-abetic nephropathy patients. METHODS:A total of 108 patients with early diabetic nephropathy selected from our hospital during May 2014-Dec. 2015 as research objects were divided into group A,B,C,with 36 cases in each group. All groups were given Ramipril tablets,5 mg for group A,2.5 mg for group B,1.25 mg for group C,qd,for 8 weeks. Blood pressure(SBP,DBP)and renal function indexes(24 h urine protein,β 2-microglobulin,UAE)were compared among 3 groups before and after treatment. The occurrence of ADR was also recorded in 3 groups. RESULTS:Before treatment,there was no statistical significance in blood pressure or renal function indexes among 3 groups(P>0.05). After treatment,blood pressures 24 h urine protein,β2-microglobulin and UAE of 3 groups were decreased significantly;those indexes of group A were significantly lower than group B and C,with sta-tistical significance(P<0.05). There was no statistical significance in each index between group B and C(P>0.05). Both hypoten-sion and hypoglycemia occurred in 3 groups during treatment,but were recovered after stopping treatment. CONCLUSIONS:High dose of ramipril(5 mg,qd)shows good effects on early diabetic nephropathy and reduces urinary protein excretion,but doesn't af-fect its safety.

Three compounds were isolated from the leaves of Rabdosia amethystoides (Benth) C.Y.Wu et Hsuan. They were identified as Irabdosinaiol (Ⅰ), oleauolic acid (Ⅱ), ?-sitostcrol (Ⅲ) on the basis of chcmical reactions and spectral data. compounds Ⅰ and Ⅱ were isolated for the first time from this plant.

Objective To investigate the relationship between the polymorphism of adiponectin -11 ,377C> G gene and the risk of coronary heart disease(CHD). Methods A total of 126 CHD patients and 130 healthy controls were enrolled and the frequency of each genotypes and allele gene of adiponectin -11 ,377C > G were detected by polymerase chain reaction fragment length polymorphism (PCR-RFLP). Results (1) The adiponectin gene -11,377C > G sites existed gene polymorphism and the three genotypes were GG, CG and CC. (2) There was statistical difference between CHD group and control group; The G allele frequency of CHD group was significantly higher than that in control group (P < 0.05); The frequency of the C allele gene in CHD group was significantly decreased (P < 0.05). (3) There was no statistical difference of frequency distribution of each genotype and allele gene of adiponectin -11,377C > G between acute coronary syndrome (ACS) group and stable angina group . ( 4 ) The risk of CHD were increased in CHD patients with G allele gene of adiponectin-11,377C > G (P < 0.05). Conclusions The polymorphism of adiponectin -11,377C > G is associated with the increased risk of CHD. The increased G allele gene frequency may represent the increased risk of CHD.
