OBJECTIVE:To investigate the effects of Shenmai injection combined with sodium ferulate on infarct size and relat-ed indicators of patients with acute myocardial infarction. METHODS:110 patients with acute myocardial infarction were randomly divided into control group(55 patients) and observation group(55 patients). Patients in the control group received oxygen inhala-tion,coronary expansion by nitrates,water and electrolyte regulation and acid-base balance regulation,thrombolytic fibrinolytic agent utilization,sedation and analgesia by analgesics and other conventional treatments. Meanwhile,50 ml Shenmai injection was given to the control group,dissolved in 200 ml 5% Glucose injection,intravenously,twice a day;observation group was addition-ally given 0.2 g Sodium ferulate for injection,dissolved in 200 ml 5% Glucose injection,intravenously,twice a day. The treat-ment course for both groups was 14 d. Clinical efficacy in 2 groups was observed,myocardial infarction size before and after treat-ment was recorded,hemorheology indexes(whole blood viscosity,fibrinogen and erythrocyte aggregation index),catdiac enzymes index homocysteine(Hcy),and growth arrest-specific gene product 6(Gas6)before and after treatment together with the incidence of adverse reactions were detected. RESULTS:The total effective rate in observation group was significantly higher than it in con-trol group. The difference was statistically significant(P<0.05);before treatment,there were no statistically significant differences in the myocardial infarction size,hole blood viscosity,fibrinogen,erythrocyte aggregation index,and blood level of Hcy and Gas6(P>0.05). After treatment,the myocardial infarct size in 2 groups was reduced,hole blood viscosity,fibrinogen and erythro-cyte aggregation indexes were reduced,and these in observation group were lower than in control group;in the 8 day during the treatment,serum level of Hcy in observation group was reduced;in the 15 day,blood level of Hcy and Gas6 in observation groups was reduced,serum level of Hcy in control group was reduced,and these in observation group was lower than in control group. The differences were statistically (P<0.05). And there were no obvious adverse reactions during treatment. CONCLU-SIONS:Based on conventional treatment,Shenmai injection combined with sodium ferulate shows significant efficacy in the treat-ment of acute myocardial infarction,and can reduce blood level of Hcy and Gas6,improve hemorheology indexes and narrow the myocardial infarct size.

OBJECTIVE:To compare clinical efficacy,safety and economy of urokinase and alteplase each combined with Enoxaparin sodium in the treatment of acute ST segment elevation myocardial infarction (STEMI). METHODS:80 STEMI pa-tients were randomly divided into control group and observation group,with 40 cases in each group. Both groups received Aspirin enteric-coated tablet for antiplatelet aggregation,and Clopidogrel hydrogen sulfate tablet for anticoagulation before thrombolysis. Control group were given urokinase 1 500 000 U added into 0.9% Sodium chloride injection 100 ml,ivgtt,within 30 min;given Enoxaparin sodium injection 7 500 U intramuscularly 12 h after thrombolysis,for 3-5 d. Observation group was given Enoxaparin sodium 60 U/kg,ivgtt,1 mg/ml Alteplase for injection 8 ml with intravenous push,other 42 ml ivgtt within 90 min;continued to receive Enoxaparin sodium with 12 U/(kg·h)micro-pump for 48 h,followed by Low molecular weight heparin calcium injection 5 000 U intramuscularly,bid,for consecutive 5 d. Clinical efficacy of 2 groups were observed,and thrombolytic recanalization situa-tion were observed 30,60,90 and 120 min after thrombolysis. ECG,cost-effectiveness and ADR were also observed. RESULTS:The effective rate of observation group(92.50%)was significantly higher than that of control group(85.00%). The rates of throm-bolytic recanalization in observation group 60,90 and 120 min after thrombolysis were significantly higher than in control group, with statistical significance(P<0.05). Q wave time,Qwave/Rwave and ST segment deviation of observation group after treatment were significantly lower than those of control group,with statistical significance(P<0.05). The total hospitalization cost of obser-vation group was significantly higher than that of control group,with statistical significance(P<0.05);there was no statistical sig-nificance in effective rate and the per unit cost of thrombolytic recanalization rate (P>0.05). The incidence of ventricular aneu-rysm,pericardial effusion,heart failure or cardiac shock,angina pectoris after infarction,severe arrhythmia,death and other as-pects in observation group were significantly lower than in control group,with statistical significance(P<0.05). CONCLUSIONS:Alteplase and enoxaparin thrombolysis therapy is better than urokinase and enoxaparin for STMEI in respects of clinical efficacy, and thrombolytic recanalization with less ADR and better safety;urokinase is cheaper and better than alteplase in cost-effectiveness ratio. Both of them can be used after careful consideration.

The retention mechanism of acid drugs such as naproxen, ibuprofen, diclofenac, phenylalanine and 2,4-dichlorophenoxy acetic acid in microemulsion liquid chromatography has been discussed.The reten tion modeling between capacity factors (k') of acid drugs in microemulsion liquid chromatography and concen tration of surfactant, cosurfactant and lipophilic organic solvent and pH value was set.The results showed the effect of change of concentration of surfactant, cosurfactant and lipophilic organic solvent and pH value on capacity factors of acid drugs in microemulsion liquid chromatography was fully consistent with the theoretical modeling.The retention modeling can better reflect the effect of composition of microemulsion solution and pH value on retention behavior of acid drugs in microemulsion liquid chromatography.

Objective To investigate the condition of inflammation and prethrombotic state (PTS) of the aged patients with coronary heart disease(CHD) complicated with esstential hypertension(EH) and type 2 diabetes mellitns(T2DM). Methods The levds of fasting plasma hs-CRP,D-D and VWF were all measured in 86 CHD patients with EH,84 patients with T2DM,80 patients with EH and T2DM,91 CHD patients and 79 normal cases. Results Compared with normal group,diseases groups had significantly higher hs-CRP,D-D,and VWF,but compared with CHD with EH and T2DM group,other diseases groups had lower hs-CRP,D-D and VWF(P <0.05) ;The concentration of serum hs-CRP was positively correlated with D-D and VWF in CHD group (P < 0. 05). Conclusion The inflammation and hypercoagulable state is more significant in CHD patients with EH and T2DM,thns the levels of plasma hs-CRP,D-D and VWF play an important role in the treatment.

Objective To analyse the pregnancy rate after treatment of tubal pregnancy with the systemic methotrexate (MTX) injection Methods From March 1985 to August 1999, 129 women with confirmed unruptured tubal pregnancy,and desiring to conceive were selected Among them 60 women were successfully treated with systemic MTX, and 69 with unilateral salpingectomy All cases were followed up for 1～15 years Results The rates of subsequent intrauterine pregnancies (IUP) in the MTX group was 73% (44 cases) and of recurrent extrauterine pregnancies (EP) was 8% (5 cases) Among 69 patients treated by salpingectomy, the rates of IUP and EP was 70% (48 cases) and 4% (3 cases) respectively The differences between the two groups were not statistically significant Conclusions The effect of conservative management with MTX was similar to those of salpingectomy The rate of subsequent pregnancy did not increased

The reduced and total vitamic C contents in 40 kinds of vegetables and melons and 18 kinds of fruits were measured. Their variations in different seasons were also investigated.The results showed that, many vegetables and melons were rich in vitamin C in different seasons, such as Chinese cabbage, shallot, spinach, chives in spring, cabbage, spinach, radish, sweetbell greenpepper in summer and chili greenpepper, cabbage, spinach, Chinese cabbage, potato, Chinese potato, turnips, etc. in autumn and winter.The contents of vitamin C in some vegetables and fruits are similar to those listed in "The Composition Table of Food" edited by Institute of Health, Chinese Academy of Medical Science, Beijing.The content of vitamin C of some species varies with seasons, which in general, is higher in autumn than in winter, and much will be lost during the storage period prior to next spring.There is a wide difference among various kinds of fruits. Jujubes are the richest, then the hawthorns and oranges, while some others are very low.Some vegetables have been subjected to blanching before freezing. The contents of reduced and total vitamin C preserved for 2-3 months' in a cold storage were reduced to 4.6-58.4% or 48.2-66.0% of their original contents.

ObjectiveTo investigate the effect of urinary kallidinogenase on the expression of Bcl-2 and Bax in cerebral ischemia-reperfusion injury of rats.Methods Forty eight male adult Sprague-Dawley rats were randomly assigned into four groups: sham operation group, model group,normal saline group andurinary kallidinogenase group.The middle cerebral artery occlusion reperfusion model was made by the suture method. After focal cerebral ischemia-reperfusion, the animals were neurologically assessed on a 5 point scale. The levels of Bcl-2 and Bax expression were measured by immunohistochemical and RT-PCR.Results In model and normal saline group, the expressions of positive Bcl-2 neurocytes and mRNA [(14.28±2.54)/HP, 0.551±0.068 and (16.54± 1.84)/HP, 0.585 ± 0.084] were significantly increased compared with the sham operation group [ (7.58 ± 0.97 )/HP、 0.324 ± 0.042] ( P ＜ 0.05 ) ; The expressions of Bax positive neurocytes and mRNA[( 24.38 ± 3.58 )/HP, 0.540±0.076 and (26.74 ±4.04) /HP, 0.527 ± 0.065] were significantly increased than the sham operation group [ (8.24±1.95 )个/HP, 0.309 ± 0.037] (P ＜0.05). After treatment with urinary kallidinogenase, the expressions of Bcl-2 positive neurocytes and mRNA [(25.61±3.41)/HP, 0.791 ±0.096] were upregulated ( P＜0.05), and the expressions of Bax positive neurocytes and mRNA [( 18.54 ± 2.38)/HP, 0.359±0.053] were down regulated (P＜0.05), compared with model group and normal saline group.ConclusionsUrinary kallidinogenase is significantly related to the upregulation of Bcl-2 expression and the downregulation of Bax expression, which suggest that urinary kallidinogenase could be related with the inhibitory effects on ischemic neurocyte apoptosis.
