OBJECTIVE:To study pharmacokinetics of domestic and imported Phenazopyridine hydrochloride tables and bioavailability of domestic tablets, and to evaluate the bioequivalence of two kinds of tablets. METHODS: A randomized crossover design was performed in 18 healthy male volunteers. They received a single oral dose of domestic or imported tablets 200 mg. Plasma concentration of phenazopyridine hydrochloride was measured by HPLC. The pharmacokinetic parameters were calculated by 3p97 software and relative bioavailability was evaluated. RESULTS: The plasma concentration-time curves of domestic and imported tablets conformed to one-compartment model. Main pharmacokinetic parameters of domestic tablets vs. imported tablets were as follows: t1/2Ke(3.52?2.03) h vs. (3.18?1.85)h; tmax(0.76?0.33) h vs. (0.79?0.43)h; Cmax(76.41?70.15) ng?mL-1 vs. (75.49?70.37) ng?mL-1; AUC0~8(159.10?116.32) ng?h?mL-1 vs. (164.65?129.89) ng?h?mL-1; AUC0~∞(237.12?115.06) ng?h?mL-1 vs. (262.69?155.05) ng?h?mL-1. The relative bioavailability of domestic tablets was (96.63?14.05)% compared with imported tablet. There was no significant difference between the pharmacokinetic parameters of two formulations by variance analysis, t-test and 1-2? confidence interval method. CONCLUSION: The domestic and imported tablets are bioequivalent.

Objective To investigate question comprehension and production among agrammatic aphasics, and to explore the mechanisms of any dysfunction in questioning.Methods Twenty aphasics were recruited in this study.According to the Chinese Agrammatism Battery,10 were classified as agrammatic (the agrammatic group) and 10 as non-agrammatic (the non-agrammatic group).Ten normal subjects served as a control group.All the subjects were tested in terms of their comprehension and production of questions using a set of general and what-where-who- why questions (wh-questions).Results No significant difference was found between the two experimental groups with regard to the correct comprehension and production of both general and wh-questions.However,there was a sig- nificant difference in correctness between comprehension and production.The performance of the agrammatic aphasics was worse than that of the non-agramatics and the normal subjects.Conclusion The impaired question comprehen- sion and production of Chinese agrammatic aphasics has its own characteristies which can form a basis for rehabilita- tion planning and outcome prediction.

Objective To investigate the number and activities changes of peripheral blood endothelial progenitor cells (EPCs) in continuous ambulatory peritoneal dialysis (CAPD) patients,and explore the connection between EPCs' number and the levels of advanced glycosylation end products (AGEs),homocysteine (Hcy) and C-reactive protein (CRP).Methods Twenty-five CAPD patients and thirty healthy volunteers were involved.Total mononuclear cells (MNCs) were isolated from peripheral blood of patients.EPCs were characterized as adherent cells by double staining of FITCUEA-1 and DiL-AcLDL binding,and were further demonstrated by positive cells of CD34,CD133 and KDR using flow cytometry.The abilities of cell proliferation,adhesion and migration were further observed by fluorescent microscope.The correlations between the CEPCs' number and the levels of AGEs,Hcy and CRP were analyzed.Results The number and activities including migration and adhesion of EPCs in CAPD group were significantly lower than control group (P < 0.05).The levels of serum AGEs,Hey and CRP in CAPD patients were increased (all P<0.05) and had negative correlation with EPCs' number.Conclusions The number and activities of EPCs decrease in patients with CAPD,and EPCs' number is negatively correlated to the levels of AGEs,Hcy and CRP.

OBJECTIVEThe multi-center, randomized, double-blind, double-simulated and positive-control trial was used to verify the contribution degree of Bushen Huoxue for the treatment of ovulatory dysfunction caused infertility, which provided scientific basis for clinical treatment.
METHODAccording to diagnostic, inclusion and exclusion criteria, we observed 349 patients which were divided into the treated group (n = 177, treated with Bushen Huoxue ricipe) and control group (n = 172, treated with clomiphene). Ovulation rate, pregnancy rate, clinical effective rate of traditional Chinese medicine, endometrium and diameter of dominant follicle were observed. Serum reproductive endocrine hormones were assayed before and after treatment.
RESULTThe treated group showed ovulation rate of 69.34%, with pregnancy rate of 41.35%. The clinical effective rate of treated group and control group were 91.73% and 80.77%. There was remarkable difference in endometrium (P < 0.05) and remarkbale difference in sex hormones PRL and E₂in treated group at prior-treatment and post-treatment (P < 0.05). No adverse effects were found in the experiment. Security indicators did not show abnormal change.
CONCLUSIONThe comparison between the two groups showed that the treated group was significantly different from control group in the pregnancy rate (P < 0.05), without notable difference in ovulation rate. There was significant difference in clinical effective rate between the treated group and control group. Both the two groups could contribute to the mature development and discharge of the follicles. The growth of endometrium and endometrial receptivity in the treated group were higher than control group. The treated group has regulatory effect on PRL and E₂.

BACKGROUND:There are few reports concerning effects of warming the yang and benefiting the marrow for the knee osteoarthritis on the expression of matrix metal oproteinase.
OBJECTIVE:To observe the effect of warming the yang and benefiting the marrow on the expression of matrix metal oproteinase in rabbit models of knee osteoarthritis.
METHODS:Of 96 healthy adult New Zealand rabbits, 72 rabbits were randomly selected for making rabbit models of knee osteoarthritis using plaster external fixation. After success model establishment, the rabbits were randomly assigned to three groups. Model group was left intact. Chinese medicine group received daily intragastric administration of drug extract 24 mL/kg. Drug control group was daily intragastrical y administered Puli Capsule (glucosamine hydrochloride) 24 mg/kg, once a day, until the eighth week of success model induction. An additional 24 New Zealand rabbits served as blank controls.
RESULTS AND CONCLUSION:Using quantitative PCR, matrix metal oproteinase-1, matrix metal oproteinase-3 and matrix metal oproteinase-13 expression was significantly higher in the model group than that in the other three groups. Matrix metal oproteinase-1, matrix metal oproteinase-3 and matrix metal oproteinase-13 expression was significantly lower in the Chinese medicine group and drug control group than that in the model group. These results indicated that warming the yang and benefiting the marrow for knee osteoarthritis in rabbits could effectively inhibit the expression of matrix metal oproteinase in rabbits.

Objective To investigate the usage of distortion product otoacoustic emissions(DPOAE) in normal infants hearing screening.Methods One hundred infants(200 ears) without clinical condition of illness were checked in GSI 70 DPOAE screening.The pure tones were 2,3,4 kHz,the OAE screener scored the test result as a pass,when the responses were above the PASS/REFER line and the signal-to-noise was at least 10 dB.Results Ninty-four infants(188 ears) passed hearing screening. Four infants(8 ears) with ceruminous impaction didn′t pass screening;after extracting impacted cerumen from the external auditory meatus,the 4 infants(8 ears) passed screening.Two infants(2 ears) with secretory otitis media didn′t pass screening,but after medicine treatment for 1 week,they passed screening too.Conclusion DPOAE has advantages in infants hearing screening.J Appl Clin Pediatr,2006,21(3):168-169
