OBJECTIVE:To study the best preparation technology of Gross Saponins tribullu terrestris droping pill. METHODS: The ratio of Gross Spongines Tribullu terrestris to matrix, dripping temperature, dripping distance and dripping speed were investigated by preliminary test and orthogonal test with sphericity, the variation coefficient of weight of pill,time limit of dissolution and appearance of the dropping pill were taken as scoring indexes. Meanwhile, the technical conditions were optimized by orthogonal test on the basis of preliminary test.RESULTS: The optimal technical conditions were as follows: the ratio of matrix to Gross Saponins Tribullu terrestris was 5∶1;the dripping temperature was 85 ℃;the dripping speed was 8 d?min-1 and the dripping distance was 12 cm.CONCLUSION:The technology is simple, feasible and the evaluation indexes were reliable and reasonable and it can meet the requirement for dripping pill specified in China Pharmacopeia (2005 Edition).

Objective To study the effect of dexmedetomidine and midazolam on hemodynamics and sedation in patients with nasal intubation.Methods Forty patients whose ASA grade Ⅰ-Ⅱ and anticipated difficult airway were randomly divided into dexmedetomidine group(group D,20 cases)and midazolam group(group M,20 cases)according to the admission number.In group D,dexmedetomidine 1 μ g/kg were constant speed pumped in 10 minutes.In group M,midazolam 0.03 mg/kg were intravenous injected.Then nasal intubation were carried.Systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial blood pressure(MAP),heart rate(HR),pulse oxygen saturation(SpO2),Ramsay sedation score,rate-pressure product(RPP),tip perfusion index(TPI)were recorded and compared before anesthesia (T0),fiberoptic bronchoscope pass by later nostril(T1),to spy on epiglottis(T2),intubation succeed(T3),after intubation 1 minute(T4)and after intubation 3 minutes(T5).Airway score and postoperative visit were evaluated.Results SBP,DBP,MAP,HR,RPP in group M were significantly higher at T1-T3 than those at T0 (P＜0.05),and were significantly higher than those in group D at the same time(P＜ 0.05).There was no significant difference in group D(P ＞ 0.05).Ramsay sedation score and TPI at T1-T3 in group M were significantly lower than those at To(P ＜0.05).Ramsay sedation score and TPI at T1-T5 in group D were significantly higher than those at T0(P ＜ 0.05),and were significantly higher than those in group M at the same time(P ＜ 0.05).The rate of airway score 1 score and intubation satisfaction in group D were significantly higher than those in group M[100％(20/20)vs.30％(6/20),90％(18/20)vs.50％(10/20)](P＜ 0.05).The rate of throat ache in group D was significantly lower than that in group M[5％(1/20)vs.35％(7/20)](P ＜0.05).Conclusions For difficult airway patients with nasal intubation during dexmedetomidine infusion,hemodynamics is stable and sedation is satisfied.

Objective To observe the regulating effect of inhaling glucocorticoid on imbalance of IL-4/interferon-?(IFN-?) cytokines in children with first onset wheezing .Methods IL-4 and IFN-? levels were examined in separated serum of 60 children wheezing with first onset wheezing,they were divided into abnormal level of IL-4/IFN-? group (n=38) and normal level of IL-4/IFN-? group(n=22,group C) depending on the level of IL-4/IFN-?,and 38 cases with abnormal level of IL-4/IFN-? were randomly divided into group A and B.Group B and C were given routine treatment without intervening treatment,while group A inhaled beclomethasone dipropionate aerosols for 3 months after routine treatment.Twenty healthy children for routine physical examinations in the same period were selected as healthy control group,who were examined for IL-4 and IFN-? with the same methods.Results Before treatment,the levels of IL-4 and IL-4/IFN-? in group A and B were significantly higher than those in group C and healthy control group(Pa

BACKGROUND: The quality of life(QOL) of patients with lung cancer is ffected due to depression, reduced lung function, subjective reduced body force, fatigue, and poor stamina, etc., and the survival of the patientswould be affected by complications or advanced stage cachexia.OBJECTIVE: To investigate the relationship between three gene proteins including p53, p27 and bcl-2 and the pathological characters of non-small cell lung cancer (NSCLC).DESIGN: An experimental trial by employing pathological specimens as subjects.SETTING: Department of respiration of a university affiliated hospital and the Central laboratory of a university.PARTICIPANTS: Totally 76 specimens of NSCLC after surgical resection between June 1997 and December 2002, which were all primary lung cancer without any other therapy.METHODS: The expression of three gene proteins in 76 NSCLC specimens was detected by SP immunohistochemical analysis.MAIN OUTCOME MEASURES: Positive expression of p53, p27 and bcl-2.RESULTS: Among 76 specimens, 28 cases(37%, 28/76) with excessive expression of p53, 34 cases(45%, 34/76) with excessive expression of p27, 37 cases(49%, 37/76) with excessive expression of bcl-2, and 7 cases with excessive expression in all three proteins. The positive expression of p53 elevated with the reduced gradation in differentiation; bcl-2 and p27positive expressions reduced with the reduced gradation in differentiation and there was significant difference between high-differentiation group and low-differentiation group( P ＜ 0. 05) . However, there was no significant relationship between the positive expressions of three proteins and the histological classification, lymph node metastasis, and pathological aging of lung cancer( P ＞ 0.05).CONCLUSION: The excessive expression of p53, p27 and bcl-2 genes might be related with the occurrence and development of NSCLC.

Aim To investigate the therapeutic value of fosinopril in heart failure.Methods Thirty SD rats were divided into three groups at random.Rats in heart failure group and fosinopril group were given an 8 weeks overswimming exercise to induce heart failure and the heart failure rats in fosinogril group were treated with fosinopril orally (2 mg?kg?d-1) for 6 weeks.14 weeks later the hemodynamic indexes, myocardiac apoptosis rate, left ventricular mass index (LVMI) and myocardiac interstitial fibrosis were determined.Results The hemodynamic indexes in heart group were remarkably different from those in normal control group, while there was a significant improvement in fosinopril group (P
