OBJECTIVE:To establish RP-HPLC method for the simultaneous determination content of rabeprazole(RAB)and its two metabolites thioether-rabeprazole(TE)and demethylated thioether-rabeprazole(DMTE)in human plasma.METHODS:The plasma samples were extracted with ethyl acetate;The Diamonsil C 18 reversed-phase column was used as analytical column,the mobile phase was consisted of methanol-water-glacial acetic acid-triethylamine(40∶60∶0.4∶0.1)with a flow rate at1.0ml/min,the ultraviolet detection wavelength was288nm.RESULTS:Good separation of chromatographic peaks of RAB,TE and DMTE were manifested.The mean recovery of which were110.40%,87.28%and98.21%respectively.CONCLUSION:The method was sensitive and accurate,and it meets the requirements for the study of pharmacokinetic of rabeprazole.

Objective To study the characteristics and clinical value of blink reflex in patients with diabetes mellitus. Methods Blink reflex were measured in 40 diabetes melletus and 30 normal adults. Results The result showed that diabetic group R1, R2 and R2' wave latency was significantly longer than the control group,meanwhile their amplitudes were significantly lower than that of control. And to 112 and R2' extended significantly,which showed that the damage to the central nervous system in diabetes can affect the brain stem. With the extension of duration of diabetes BR abnormal rate gradually increased. Conclusion It was concluded that BR provide an objective and sen-sitive index for the damage of the central nervous system in diabetes.

Objective To explore the effect of clinical application of self-starting devices in patients after major abdominal surgery. Methods From January 2007 to June 2009, 90 patients with major abdominal surgery were randomly divided into the observation group and the control group with 45 patients in each. The observation group using self-starting devices 6 hours after surgery, the control group used the traditional approach to sit and lie. The effect of the two groups was compared. Results Significant difference existed in recovery of bowel movement, wound healing and incidence of pressure sore between the two groups. Conclusions Application of self- starting devices in patients after major abdominal surgery can promote recovery of bowel movement and wound healing and prevent incidence of pressure sore, so that patients can recover early.

Objective To compare the short-term perioperative outcomes of video-assisted mini-thoracotomy(VAMT),multiple port-video-assisted thoracoscopic surgery(MP-VATS)and single utility port-VATS(SP-VATS)in treatment of early stage non-small cell lung cancer(NSCLC).Methods A total of 157 cases of early stage NSCLC patients were collected and divided into three groups:66 cases received VAMT treatment as group VAMT;45 cases received MP-VATS treatment as group MP-VATS;46 cases received SP-VATS treatment as group SP-VATS.The intraoperative and postoperative conditions,lung function indexes including forced expiratory volume in one second(FEV1),forced vital capacity(FVC)and maximal voluntary ventilation(MVV)among the groups were compared.Results There were no significant differences in the operation time and the number of lymph node dissection among the SP-VATS group,MP-VATS group and group VAMT[(154.89±32.34)min vs(158.43±36.78)min vs(161.21±40.02)min,(12.34±4.55)pieces vs(12.47±3.81)pieces vs(11.78±3.32)pieces,P>0.05];the incision length,blood loss,amount and time of postoperative drainage and the postoperative ambulation in groupSP-VATS were significantly lower than group MP-VATS and VAMT[(4.11±0.65)cm vs(6.42±0.65)cm vs(12.14±2.23)cm;(170.31±45.68)ml vs(166.23±43.21)ml vs(228.96±63.21)ml;(623.42±231.56)ml vs(681.23±278.54)ml vs(924.54±324.51)ml;(5.27±1.32)d vs(7.43±2.27)d vs(7.66±2.89)d;(3.36±0.78)d vs(4.62±1.26)d vs(4.78±1.43)d,all P<0.05].The time of postoperative drainage and postoperative ambulation in group SP-VATS was significantly lower than group MP-VATS(P<0.05);The rate of postoperative complications in group SP-VATS was 2.17%,significantlylower than 15.15% in group VAMT(P<0.05);The postoperative recurrence rate within 6 months among the group SP-VATS, group MP-VATS and group VAMT were no significant difference(6.67% vs 4.44% vs 3.03%,P>0.05);After surgery,the lung function(FEV1,FVC,MVV)among the three groups were significantly decreased,and the group SP-VATS was significantly higher than VAMT group(P<0.05),but there was no significant difference with group MP-VATS(P>0.05).Conclusion The SP-VATS for early stage NSCLC has similar short-term efficacy with VAMT and MP-VATS,but SP-VATS has faster recovery and maller postoperative pulmonary dysfunction.

OBJECTIVE:To establish a method for the contents determination of 5 coumarins in sulphur-fumigated and no sul-phur-fumigated Glehnia littoralis,and investigate the effect of sulphur fumigation on the coumarins in G. littoralis. METHODS:HPLC was performed on the column of Hypersil ODS C18 with mobile phase of acetonitrile-0.1% phosphoric acid (gradient elu-tion)at a flow rate of 1.0 ml/min,detection wavelength was 295 nm,column temperature was 30 ℃,and the volume was 20 μl. RESULTS:The linear range was 0.121 5-12.15 μg/L for psoralen,0.389-38.9 μg/L for xanthotoxin,0.055-5.5 μg/L for bergapten, 0.070 5-7.05 μg/L for imperatorin and 0.092 5-9.25 μg/L for isoimperatorin(r≥0.999 7);RSD of precision test was lower than 1.0,RSDs of reproducibility and stability tests were lower than 3.0;recovery was 98.01%-101.97%(RSD<3.0%,n=6). CON-CLUSIONS:The content of coumarins in G. littoralis was obviously decreased after sulphur fumigation. the method is simple and accurate,and canbe used for the quality control of sulphur-fumigated and no sulphur-fumigated G. littoralis.
