Objective To investigate the correlation between the degree of pathogenetic condition and cogni-tive impairment in young OSAHS patients. Methods Sixty-three patients (18~44 years old) were divided into 3 groups according to the assessment criteria regarding the degrees of pathogenetic conditions of hypoxemia and its persistence time: mild group(the lowest SaO2 ≥ 85 %, n = 20 ), moderate group (the lowest SaO2 : 65 ~ 84 %, n =24), and severe group (the lowest SAO2<65%, n= 19). Twenty-five healthy young adults were selected as the control group. All the subjects were tested with event-related potential, namely P300, the polysomnogram and the mini-mental state examination scale(MMSE). Results P300 latency in patients of three OSAHS groups was sig-nificantly prolonged as 326.1±12.7, 346.9±19.1, and 34.9±18.3 ms, as compared with those of control group: 311.9±18.3 ms (P< 0.05, respectively). In severe group, P300 latency was markedly increased compared with mild and moderate groups(P<0.01, P<0.05, respectively). No obvious differences were observed between mild and moderate groups(P=0. 095). The difference of hypoxemia lasting time could influence the P300 latency, such as when the hypoxemia lasting time was 4~60 seconds, the latency was 338. 12±13.7 ms, and when the hypoxemia lasting time increased to 60 ~ 140 s, the latency was prolonged to 354.74±16.7 ms(P = 0. 031 ). There was no difference among all groups in the P300 amplitudes. The MMSE scores for all patients were within normal limits andthere were differences between serve and control group(RA -RB=9. 91, P= 0. 003). Conclusion Among patients with OS-AHS, the impairment of cognitive function is con'anon. The degrees of pathogenetic conditions of hypoxemia and its lasting time may be used to evaluate the impairment degree of cognitive function in patients with OSAHS.

Lactic acid production of twelve strains of LAB isolated from broiler intestine and tolerance property of three strains were investigated. The results of lactic acid production showed that among all strains K6 exhibited the most rapid production during the first twelve hours, the seconds were K9 and C1; D17 exhibited the highest production of lactic acid by twenty-four hours, C1 exhibited the highest production of lactic acid by forty-eight hours. The pH values in three strains of K9、D17 and C1 culture showed the fast decline during the first twelve hours, with the final values significantly lower than those of other strains cultures. The results of tolerance property showed that the survival counts of C1could be detected when pH value was at 2 after three hours, but the survival counts of D17 and K9 could not be detected after one hour. When pH value was at 2.5 after three hours ,the survival counts of C1 declined from 10~ 8.2 /mL to 10~ 4.8 /mL, K9 from 10~ 8.2 /mL to 10~ 4.6 /mL, the survival counts of D17 could not be detected. 0.08% bile had few effects on the survival counts of three strains; when incubated in the medium with 0.40% bile, the survival counts of C1 declined from 10~ 8.4 /mL to 10~ 6.5 /mL,D17 from 10~ 10.3 /mL to 10~ 7.5 /mL, and K9 from 10~ 9.8 /mL to 10~ 7.7 /mL. When the group treated with 37℃ for 20 minutes was served as the control, the survival counts of C1 and K9 was not detected when treated with 80℃, but the survival counts of D17 were 10~ 4.9 /mL, when treatment with 65℃ the survival counts of C1 and K9 decreased significantly .

A rapid method for the simultaneous determination of berberine (BBR), matrine (MT) and oxymatrine (OMT) by nonaqueous capillary electrophoresis (NACE) was developed. Optimum separation of the analytes was obtained on a 50cm×50μm i.d. fused-silica capillary using a non-aqueous buffer system of 70mM ammonium acetate, 7.0% acetic acid and 10% acetonitrile at 25kV and 20℃. The relative standard deviations (R.S.D.) of the migration times and peak areas of the three active components were 0.06%-0.20% and 0.12%-3.41% for berberine, 0.11%-0.60% and 0.74%-1.63% for matrine, 0.15% and 0.45% for oxymatrine, respectively. Detection limits of berberine, matrine and oxymtrine were 0.18μg/mL, 4.08μg/mL and 4.16μg/mL, respectively. In the tested concentration range, good linear relationships (0.9992 for berberine, 0.9988 for matrine and 0.9988 for oxymatrine) were observed. The linear calibration ranges were 0.45-360.0μg/mL for berberine, 8.16-408.0μg/mL for matrine and 20.8-416.0μg/mL for oxymatrine. This method has been successfully applied to the phytochemical analysis of alkaloids extracts from two commonly used traditional Chinese herbal drugs: Sophora flavescens Ait. (Kushen) and Cortex phellodendri chinensis (Huangbai) and their medicinal preparations.

A HPLC-MS/MS multiple-reaction monitoring (MRM) quantitative analysis was made to establish a determination method for drug concentrations of costunolide (Co) and dehydrocostuslactone (De) in blood samples in the positive ion mode, with diazepam as the internal standard substance, in order to study the pharmacokinetic process of sesquiterpene lactones costunolide and dehydrocostuslactone after the oral administration of Weichang'an pills, and provide an theoretical basis for further studies on the substance basis for the anti-diarrhea effect of Weichang'an pills. In the blood samples, Co and De showed a good linearity within concentration ranges 0.700 0-769.7, 2.510-956.0 μg x L(-1), respectively. The results of precision, stability and recovery experiences proved the stability and reliability of the plasma concentration determination method. After the oral administration, the concentrations of Co and De in plasma increased with the increase in dose, with T(max) between 10.65-12.98 h, indicating a long time to reach peak plasma concentrations; C(max) of costunolide and dehydrocostuslactone ranged between 3.750-5.450,15.34-44.52 μg x L(-1), respectively. The in vivo adsorption of Co and De conformed to the one-compartment model, with a longer time to attain the peak plasma concentrations. These results provided an experimental basis for revealing the active substance basis and clinical medication of Weichang'an pills.
