Time resolved fluoroimmunoassay (TRFIA) was used to detect the serum level of pepsinogen (PG).And the 13C urea breath test (13C-UBT) was employed to detect the Helicobacter pylori (HP) infection rate for 1060 subjects of health check-up.Statistics showed that the serum PGⅠ level of males was significantly higher than that of females.And the ratio of females with PG Ⅰ ＜ 60 μg/L and PG Ⅰ ＜ 60 μg/L + PG Ⅰ/PG Ⅱ ＜ 6 was significantly higher than that of males.The PG Ⅱ level increased with age while PG Ⅰ/PG Ⅱ decreased.The PG Ⅰ level rose gradually until age of 60 and then maintained at a high level.For the HP-positive group,the serum levels PG Ⅰ and PG Ⅱ were significantly higher than those of the HP-negative group.And the PG Ⅰ/PG Ⅱ ratio was significantly lower than that of the HP-negative group.

Objective To evaluate the efficacy and safety of fractionated CO2 laser combined with 308-nm excimer laser for the treatment of stable vitiligo.Methods Forty-nine patients with 109 lesions of stable vitiligo were enrolled in this clinical trial.Each of these lesions was equally divided into 2 parts along the longest diameter,which were then assigned into the treatment group and control group respectively.The treatment group were treated with fractionated CO2 laser radiation for 15-20 minutes once every two weeks combined with 308-nm excimer laser radiation twice weekly.The control group were only treated with 308-nm excimer laser radiation twice weekly.Efficacy was evaluated on day 3 after 12 consecutive weeks of treatment.Results After the treatment,the total response rate in the treatment group and control group was 92.7％ (101/109) and 77.1％ (84/109) respectively.The marked response rate in the treatment group and control group was 85.4％ (35/41) and 65.8％ (27/41) respectively for lesions on the face and neck (x2 =4.23,P ＜ 0.05),70.6％ (24/34) and 41.2％ (14/34) respectively for lesions on the trunk (x2 =7.27,P＜ 0.01),64.0％ (16/25) and 36.0％ (9/25) respectively for lesions on the extremities (x2 =3.92,P ＜ 0.05),5/9 and 1/9 respectively for lesions on the dorsal hands (X2 =4.00,P ＜ 0.05).The number of sessions of 308-nm excimer laser therapy required for the marked response of vitiligo in the treatment group and control group was 7.24 ± 1.23 and 10.81 ± 2.01 respectively for lesions on the face and neck (t =9.70,P ＜ 0.05),15.10 ± 2.47 and 18.95 ± 3.45 respectively for lesions on the trunk (t =5.29,P＜ 0.05),17.37 ± 3.84 and 21.06 ± 4.23 respectively for lesions on the extremities (t =3.23,P ＜ 0.05).No severe adverse reactions were observed in any of the patients during the treatment.Conclusion Fractionated CO2 laser combined with 308-nm excimer laser is effective and safe in treating stable vitiligo.

AIM: To determine the concentration of nisoldipine in human plasma by HPLC-MS method and investigate the pharmacokinetics of sustained and immediate-release preparations. METHODS: A C 18 column was used to separate nisoldipine from plasma with the mobile phase of a mixture of methanol-water-acetic acid (7525 0.1) at a flow rate of 1.0 ml?min -1. MS: atmospheric pressure electronic spray ionization (AP-ESI) and ion mass spectral (m/z) of 411 were selected to quantify nisoldipine. Internal standard (IS): atmospheric pressure electronic spray ionization and m/z of 441 for nimodipine. RESULTS: The linear range of the standard curve of nisoldipine was 0.2- 50 ?g?L -1 and the determination limit was 0.15 ?g?L -1. The recovery rate was more than 70%, and intra-day relative standard deviation (RSD) and inter-day RSD were less than 10%. After being given a single dose of 10 mg nisoldipine sustained release tablet, sustained release capsule and normal tablet, the half life(t 1/2 /h) were 6.08? 1.48, 7.06? 1.80 and 3.70? 0.25, the time to peak concentration (T peak /h) were 5.4? 0.7, 5.8? 0.4 and 2.0? 0.2, the peak concentration (C max / ?g?L -1) were 3.43? 0.55, 3.71? 0.24 and 9.18? 3.78, the area under time- concentration curve (AUC 0-t / ?g?h -1?L -1) were 31.10? 5.00, 33.63? 7.16 and 32.72? 5.09. But after being given multiple doses of nisoldipine, C max/ ?g?L -1 were 5.20? 0.27, 3.91? 0.22 and 5.30? 1.04, C min / ?g?L -1 were 0.72? 0.10, 0.77? 0.07 and 0.53? 0.07, DF were 175.00%? 16.34%, 177.10%? 18.43% and 247.92%? 57.71% respectively. The bioavailability of sustained- release tablet and capsule were 96%?12% and 102%?9% respectively. CONCLUSION: The determination of concentration of nisoldipine in human plasma by HPLC-MS method is sensitive and accurate. It can be used for the investigation of the bioavailability and pharmacokinetic of nisoldipine.

AIM: To establish a sensitive HPLC method for determining the concentrations of paeonol in human plasma and to evaluate its pharmacokinetic characteristics. METHODS: A single oral dose of 160 mg paeonol capsules was given to 24 Chinese healthy volunteers. Paeonol was separated on a XB-C18 column with tetrahydrofuran-methanol-water-phosphonic acid (6∶60∶34∶0.1, V∶V) as mobile phase. The plasma concentrations of paeonol were determined and its pharmacokinetic parameters were calculated and evaluated using DAS 2.0. RESULTS: The linear range of the paeonol was 10-500 ng/mL and the determination limit was 10 ng/mL. The main pharmacokinetic parameters, as Cmax, tmax, t1/2,AUC0-3, AUC0-∞ after a single dose of paeonol capsules were (116±46)ng/mL,(1.02±0.13) h,(1.03±0.35) h, (174±45) ng/mL, (217±56) ng/mL,respectively. CONCLUSION: The HPLC method for determining paeonol concentration in plasma is rapid, sensitive and suitable for pharmacokinetic studies.

Objective To study the analgesic sites and mechanism of total alkaloids in Papaver nudicaule (TAPN). Methods The sites of analgesic action of TAPN were observed by adopting Formalin test and two different routes of intracerebroventricular (icv), intrathecal (ith) in mice and rats and comparing ED 50 of TAPN in writhing reaction in mice induced by acetic acid by ip and iv administration. Results TAPN significantly lowered pain score of the early and late phase of Formalin response and was more sensitive in the late phase. Inhibition of TAPN at the same dose by ip administration in writhing reaction in mice induced by acetic acid was stronger than that by iv. The ED 50 value of TAPN at any time by ip administration was lower than that by iv administration. By means of central microinjection, TAPN by icv administration induced remarkable analgesic effect in mice, but TAPN by ith administration had no significant analgesic effect. Conclusion The sites of analgesic action of TAPN are mainly at periphery. TAPN has also central analgesic effect, and the site may be at the level above the spinal cord.
