OBJECTIVE:To study the pharmacokinetics and relative bioavailability of metformin hydrochloride enteric-coated tablets and validate the bioequivalence between the domestic and the imported metformin hydrochloride enteric-coated tablets.METHODS:An oral single dose(1 000 mg)of domestic or imported metformin hydrochloride enteric-coated tablets was given to 26 healthy volunteers in a randomized crossover study.The time-concentrations of metformin hydrochloride were determined by HPLC.The pharmacokinetic parameters as well as relative bioavailability of the domestic tablets were computed.RESULTS:The concentration-time curves of the two kinds of metformin hydrochloride enteric-coated tablets were in line with one-compartment model.The main pharmacokinetic parameters of the domestic vs.the imported metformin hydrochloride enteric-coated tablets were as follows:Cmax(84.9?16.4)?g?L-1 vs.(84.5?13.8)?g?L-1;tmax(0.67?0.07)h vs.(0.77?0.08)h;t1/2 Ke(1.90?0.17)h vs.(1.79?0.19)h;AUC0～t(161.9?16.8)?g?h?L-1 vs.(157.2?19.7)?g?h?L-1;AUC0～∞(179.7?18.2)?g?h?L-1 vs.(173.4?19.2)?g?h?L-1.The relative bioavailability of the domestic enteric-coated tablets was(109.0?7.2)% as against the imported enteric-coated tablets.CONCLUSION:The two kinds of tablets were bioequivalent.

Objective:To investigate the relationship between some common risk factors of the cerebralvascular diseases and PD.Methods:Case-control study was carried out.Blood glucose,low density lipoprotein cholesterol(LDL-C)and homocysteic acid(Hcy) levels were detected by routine methods.The intima-media thickness(IMT)of carotid artery was measured by color Doppler ultrasound.The PD patients were graded by Unified Parkinson's Disease Rating Scale(UPDRS).Results:The blood glucose and Hcy in PD patients were higher than that in control group,and the LDL-C,IMT of carotid artery in PD were lower than that in control group.The Hcy was positively related to risk of PD,while IMT of carotid artery and LDL-C were negatively related to risk of PD by Spearman analysis.Conclusion:The Hcy level is a risk factor of PD.The LDL-C and IMT of carotid artery in PD patients were lower than that in control group,which suggests that the probability of PD patients who suffer from atherosclerosis is small.

To improve the quality education of medical students,we should attach importance to the construction of teaching staff,improve learning environment,strengthen selected course construction and arrange for students to take social practice.

The practical teaching of clinical medicine is in progress on the last stage of the 5-year university life,so it has the feature of the employment preparation and is influenced by a lot of factors.To make the practical teaching of clinical medicine take the right turning and get a satisfactory result,we should not only lay stress on the construction of teachers'contingents,but also bring the students'initiative to play and tighten up the management.

OBJECTIVE:To explore the clinical efficacy and safety of Leukotriene receptor antagonist combined with Gluco-corticoid nasal spray(called“intranasal steroid”for short)in the treatment of different degree of adenoidal hypertrophy(AH)com-plicated with allergic rhinitis (AR). METHODS:240 AR children with AH were randomly divided into control group,intranasal steroid group and drug combination group,with 80 cases in each group. Control group was given physiological seawater,3 presses each nostrile,in the morning and evening. The intranasal steroid group received Momestasone furoate nasal spray,one press each nostrile,qd. Drug combination group was additionally given leukotriene receptor antagonist Montelukast sodium chewable tablet,4 mg for under 5 year-old and 5 mg for 5-year-old or above,qd,at bedtime. Treatment course of 3 groups lasted for 12 weeks. The change of clinical symptoms and signs(such as nasal obstruction,snore,mouth breathing,etc)and adenoid/pharyngeal ratio(A/N ratio)were compared among 3 groups after treatment as well as the occurrence of ADR. Each group was divided into two sub-groups (medium and severe) according to the severity of AH so as to evaluate therapeutic efficacy. RESULTS:21 children withdrew from the study,including 11 cases in control group,6 in intranasal steroid group and 4 in drug combination group. After treatment,clinical symptom score and A/N in subgroups of drug combination group and intranasal steroid group were all lower than those of control group,with statistical significance(P<0.05). There was no statistical significance in clinical symptom score and A/N between drug combination group and AR complicated with medium AH subgroup from intranasal steroid group(P>0.05). Clini-cal symptom score and A/N of AR complicated with severe AH subgroup from drug combination group were lower than intranasal steroid group,with statistical significance (P<0.05). No obvious ADR occurred in 3 groups. CONCLUSIONS:Intranasal steroid alone and intranasal steroid combined with leukotriene receptor antagonist can improve clinical symptom of AR patients with AH, and reduce adenoid volume. It is suggested to use intranasal steroid firstly for medium AH complicated with AR,and additionally use Leukotriene receptor antagonist for severe AH complicated with AR.
