The administration status of enteric coated aspirin in 348 diabetic patients aged over 40 from Xujiahui Subdistrict of Shanghai was surveyed. One hundred and two out 348 patients ( 29. 3% ) used aspirin regularly, among them only 36 cases used the correct dosage (75 - 162 mg/d), accounting for 10. 3% (36/348) of all patients surveyed. The results indicate that aspirin was not used properly in diabetic patients to prevent the heart and cerebrovascular diseases,and it is necessary for medical providers to promote health education for diabetic patients.

Objective To investigate the relationship of obesity with metabolic syndrome.Methods Six hundred and ninety-seven patients were chosen from the routine physical check-up from 2003 to 2005.These cases were divided into three groups according to body mass index(BMI).The detection rate of high triglyceride(TG) and low level of high-density lipoprotein cholesterol(HDL-C) were compared among groups of different BMI levels.The detection rate of hyperglycemia,hyperuricemia and high blood pressure among groups of different BMI levels was compared.Results With BMI increasing,the detection rate of high TG and low HDL-C also increased.The difference among three groups was statistically significant(P

Objective To investigate the physical and mechanical properties of home-made bone cement mixed with different antibiotics.Methods The specimens of bone cement each of 40g were divid-ed in to6groups depending on mixed antibiotics,groupⅠmixed with1g gentamicin,groupⅡwith2g gen tam icin,groupⅢwith1g cephradine,groupⅣwith1.5g cefuroxine,groupⅤwith1g ceftriaxone and groupⅥwith out any antibiotics served as control.The dough time,compressing depth,compressive strength,bending strength and bending elastic modulus were measured respectively,elution examination of antibiotics from bone ce ment was performed by chromatography.Results The dough time and compress-ing depth of the groups were better than that of ISO5833standard,and there was no significant difference a-mong the groups.The com pressive strength and bending strength of the groupⅡwere lower than that ISO5833standard,but there was no significant difference among the groups by analysis of variance.The bending elastic modulus of the groupⅡwas lower than the control group and other groups(P

To study the chemical constituents from Zanthoxylum simulans and their anti-inflammatory activity. The constituents of Z. simulans were isolated and purified using various column chromatographies. Their chemical structures were elucidated using extensive spectroscopic methods. The compounds were assayed inhibitory activity against NO production in LPS stimulated RAW 264.7 cells. Four compounds were obtained from the ethanol extract of Z. simulans and determined to be isozanthpodocarpin B(1), kobusin (2), (+)-fargesin (3), and epieudesmin (4). Compound 1 exhibited NO production inhibitory effect with IC50 value of 14.49 µmol · L(-1). Compound 1 is a new dimeric lignan and may be serve as potential anti-inflammatory agent in the future.

Objective:Comparing the effect of different doses of simvastatin in lowering the serum lipid.Methods:79 patients were randomized into group A and group B,and were given simvastatin 10 mg*d-1 (group A) and 20 mg*d-1 (group B),respectively for a total of 8 weeks.Results:Comparing with baseline,in group A,TC,TG,LDL-C were decreased by 23.4%,20.0% and 30.7%,respectively (P＜0.01); HDL-C was increased by 17.5%.The content of serum TC,TG and LDL-C was decreased to the normal range in 12.8%,28.2% and 15.4% of the patients in group A.For the group B,TC,TG,LDL-C were decreased by 32.7%,22.8% and 42.8%,respectively (P＜0.01); HDL-C was increased by 13.7%.The content of serum TC,TG and LDL-C was decreased to the normal range in 65.0%,57.5% and 65.0% of the group B patients.Conclusion:Oral intake of 20 mg of simvastatin once a day can effectively reduce the serum lipid.The patients can well tolerate and no obvious side effect was observed in our study.

Objective To investigate the awareness of non-respiratory physicians to the diagnosis and medical treatment of chronic obstructive pulmonary disease.Methods A cross-sectional study was conducted in 370 non-respiratory physicians from 9 hospitals of Beijing.All the subjects were required to complete a self-administrated questionnaire.Chi-square test and analysis of variance were used for data analysis.Results The physicians in the first-grade hospitals had lower awareness of COPD than those in the second-or third-grade hospitals (57.5 ± 17.1,67.1 ± 15.0 and 68.9± 13.6,respectively; F=18.75,P＜0.05).Moreover,the residency and attending physicians were found to have lower awareness of COPD than chief physicians (61.4± 12.9,61.4± 15.0 and 79.3± 13.2,respectively; F=34.82,P＜0.05).Conclusion The medical knowledge on the management of COPD might be poor among non-respiratory physicians in Beijing.Primary healthcare workers and non-respiratory physicians should pursue intensive COPD training in the furture.

Objective:To determine berberine and palmatine in Phellodendron chinense Schneid.and its granules.Methods: The reversed-phase ion pair high performance liquid chromatography(RP-HPLC) was used and the validation of the method was tested.The chromatography condition was with Lichrospher C18 column(4.6 mm?250 mm,5 ?m), mobile phase was ACN∶25 mmol/L NaH 2PO 4∶25 mmol/L SDS(2∶1∶1),flow speed was 1.0 ml/min,detection wavelength was 345 nm,and temperature of column was 25℃,Phellodendron chinense Schneid.and its granules were extracted with methanol solution of hydrochloric acid.Results: The theoretical plate number of berberine and palmatine were 14 906 and 14 847,the resolution were 2.33 and 2.86,the tailing factor were 1.09 and 1.06,respectively; all the parameters were suitable for determination.The calibration curves were linear in the range of 40-500 ng,Y=698 278X-3 846,r=1.000(berberine) and 20-250 ng, Y= 536 632X- 7 738, r=0.999 9,r=0.999 4(palmatine).The intra-day and inter-day precision(RSD) at low,middle and high injection amount was all less than 2.5%(berberine) and 1.5%(palmatine).The stability(RSD) was 0.66%(berberine) and 0.70% (palmatine) in 48 h.The recurrence(RSD,n=5) was 0.11%(berberine) and 0.12%(palmatine).The limits of detection was 2.0 ng(berberine) and 1.0 ng(palmatine).The recoveries were 100.4% (RSD=0.12%,n=3) for berberine and 99.80%(RSD=0.22%,n=3) for palmatine.The contents of berberine and palmatine in 3 batch of Phellodendron chinense Schneid.and 5 batch of its granules were determined.Conclusion: Our method can be used for determination of berberine and palmatine in Phellodendron chinense Schneid.and its granules, which is simple and reliable.
