OBJECTIVE:To study the pharmacological action of Shaducao oral succus in mice.METHODS:Pole-climbing test,charcoal clearance test,ear-swelling test,ink-propelling test were conducted respectively to observe the antifatigue action of Shaducao oral succus,and its effect on nonspecific immunity,anti-inflammatory and anti-diarrhea effects on mice. RESULTS: Shaducao oral succus markedly prolonged the duration of mice in climbing pole,and it also showed remarkable antifatigue effect. High dose of Shaducao oral succus significantly enhanced mice's charcoal clearance coefficient and clearance capacity index and enhanced mice's immune function.At high,middle and low doses,Shaducao oral succus markedly ameliorated dimethyl benzene-induced otitis,significantly lowered the ink-propelling speed,and satisfactorily relieved diarrhea. CONCLUSION: Shaducao oral succus was proved to be of certain antifatigue,anti-inflammatory and anti-diarrhea effects meanwhile it could enhance the nonspecific immunity of mice.

Objective To explore clinical effect of integrative medical therapy on infantile bronchiolitis. Methods 96 infants with bronchiolitis were randomly divided into a treatment group and a control group. The treatment group was treated with integrated traditional Chinese and western medicine, and the control group was treated with western medicine exclusively. Results The disappearance time for symptoms and signs in the treatment group was shorter than that of the control group. The hospitalized time (or time for observation of outpatient infusion) of the treatment group was also shorter than that of the control group (P＜0.05). The cure rate was 78.0% and the total effective rate was 96.0%% in the treatment group. However, the cure rate was 52.2% and the total effective rate was 69.6% in the control group, which had a significant difference in the two groups (P＜0.05). Conclusion Integrated traditional Chinese and western medicine can obviously shorten course of disease and hospitalized time, and also improve the curative effect of infantile bronchiolitis.

Objective To investigate the effect of sodium ozagrel injection on hemorheology, endothelin (ET) and nitrogen monoxidum (NO) of patients with non-ST segment elevation myocardial infarction (NSEMI). Methods A total of 81 NSEMI patients were divided randomly into two groups: control group and experimental group. Isosorbide mononitrate, low molecular heparin and simvastatin were administered in the control group while sodium ozagrel was added to the experimental group apart from the above-mentioned drugs. The clinical effect of sodium ozagrel was observed. The changes in the indexes of hemorheology, ET and NO were analyzed. Results The clinical effect was significantly better in the experimental group than in the control group (P<0.05). The level of ET was obviously lower after treatment than that in the experimental group and the control group before treatment (P<0.05). The level of NO was obviously higher after treatment than that in the experimental group and the control group before treatment (P<0.05). The changes of ET and NO in the experimental group post-treatment were more significant than those in the control group after-treatment (P<0.05). The level of hemorheology index after treatment was lower than that before treatment in the experimental group (P<0.05). High-shear rate of whole blood viscosity, platelet adherence rate, and fibrin as hemorheology indexes were lower after-treatment than those pretherapy in the control group (P<0.05). Conclusion Sodium ozagrel injection could affect hemorheology,ET and NO of patients with non-ST segment elevation myocardial infarction. Thefore, the therapeutic efficacy can be better if sodium ozagrel is added to the conventional therapy.

BACKGROUND: Mental disorders of college students, especially medical college students, deteriorate year by year.Mental disorders can not only restrict healthy development of body and mind, but also cause social crisis.OBJECTIVE: To survey the prevalence of mental status and the correlation between mental status and family dynamics among medical college students.DESIGN: Randomized cluster sampling.SETTING: Center of Mental Health, the First Affiliated Hospital, Chongqing University of Medical Science.PARTICIPANTS: A total of 801 sophomores were selected from a medical university of Chongqing from November 2004 to June 2005.METHODS: ① Symptom Checklist-90 (SCL-90) was used to evaluate mental status among college students. If those students whose total scores were ≥ 200 and/or the score of any factor in SCL-90 was ≥ 3, they were regarded as having mental problem. The higher the scores were, the severer the mental problemwas. ② Family dynamics questionnaires, including family atmosphere, individuation, systemic logic and disease opinion, were used to evaluate characteristics of family dynamics. There were 4 items: family atmosphere, individuation, systemic logic and disease opinion. The more comfortable and cheerful the family atmosphere was, the lower the scores were; the greater the differentiated degrees were, the lower the scores of individuation were; the more objective the disposal of problems was,the lower the scores of systemic logic were; the more subjective the duty of recovery was, the lower the scores of disease opinion were.MAIN OUTCOME MEASURES: ① Prevalence of mental disorder; ② comparing scores of family dynamics between disorder group and normal group; ③ results of correlation analysis and step regression analysis between mental disorder and family dynamics.RESULTS: Among 801 questionnaires, 747 were involved in the final analysis. ① Prevalence of mental problem was 19.4%. ② The scores of family atmosphere, Individuation, systemic logic and disease opinion were all higher in disorder group than those in normal group, with significant differences (3.10±0.49, 2.66±0.64; 2.92±0.54, 2.77±0.58; 2.79±0.55,2.69±0.54; 2.58±0.67, 2.36±0.62, P ＜ 0.05). ③ The total score of SCL-90 was positive correlation with points of family atmosphere and disease opinion (r=0,184, 0,156, P ＜ 0.05). Family atmosphere, individuation and disease opinion were analyzed by regression equation.C0NCLUSION: Mental status of college students is closely related to family dynamics. Family atmosphere and disease opinion play a great role in mental disorder.

Objective To study dexmedetomidine on the adverse impact of ketamine based anesthesia and sedative effects in indirect inguinal hemia.Methods Eighty children underwent indirect inguinal hemia surgery were randomily divided into two groups after injected muscle with midazolam and ketamine,Group B was injectded with 0.5 μg/kg DEX,but Group A with normal saline,analgesia was with caudal block (lidocaine).The with hemodynamic,level of sedation,recovery time and CHW score were observed.The adverse reactions were recorded.Results Two groups of children have hemodynamically stable,and recovery time had no statistical significance.The two groups of CHW score in Group A (1.6 ± 0.5) points higher than in group B (0.9 ± 0.3) points (P ＜ 0.05).The restlessness rated group (1.52 ± 0.54) points was higher than in group B (0.51 ± 0.48) points (P ＜ 0.05).Compared with Group B,Group A had 12 cases of psychiatric symptoms,10 cases of involuntary movement of limbs,6 cases of severe postoperative agitation nausea,and 8 cases of vomiting (P ＜ 0.05).Conclusion 0.5μg/kg DEX can be safely and effectively used in the pediatric anesthesia,and reduce the adverse reactions caused by ketamine.
