A new biosensor was prepared based on conductive polymer poly ( 3 , 4-ethylenedioxythiophene ) ( PEDOT) and 1-pyrenebutanoic acid ( PBA) through π-π stacking, as well as hematin associated with PBA through coordinate bonds of Zr4+ and carboxyl group. Its stability and sensitivity were examined by cyclic voltammetry ( CV) , electrochemical impedance spectroscopy ( EIS) and current-time ( i-t) method. A pair of well defined and quasi-reversible redox peaks was observed when GCE/PEDOT/PBA/hematin was tested by CV in PBS without oxygen. The electron transfer rate constant was estimated to be 4. 8 s-1 . Results indicated that the PEDOT film enhanced the electron transfer process of hematin. When the i-t method was used to detect the response of biosensor to catechol with different concentrations, it displayed a linear response for the reduction of catechol in the range of 0. 5-200 μmol/L. The linear equation was i=0. 018C+0. 006 ( R=0. 9998), and the detection sensitivity was 0. 258 μA (μmol/L· cm2) with a detection limit of 0. 33 nmol/L (S/N=3). The results illustrate that the GCE/PEDOT/PBA/hematin biosensor is very sensitive and stable.

OBJECTIVE:To study the improvement effect of Celosia cristata n-butanol extracts on dysfunctional uterine bleed-ing of rats,and explore its mechanism. METHODS:60 pregnant SD rats were randomly divided into blank group,model group, Gongxuening capsule group (positive control,0.07 g/kg) and C. cristata n-butanol extracts high-dose,medium-dose,low-dose groups(4.32,2.16,1.08 g/kg),10 in each group. Except for the blank group,rats in other groups were intragastrically given mife-pristone and misoprostol on 7th of pregnancy for resulting incomplete abortion to induce models of dysfunctional uterine bleeding. Then rats in administration groups were intragastrically given relevant medicines,rats in blank group and model group were intra-gastrically given normal saline once every morning and evening,for 7 d. On 8th d of pregnancy,uterine bleeding amount,and thromboxane (TXA2),prostacyclin (PGI2) and tumor necrosis factor α(TNF-α) contents in serum were determined. RESULTS:Compared with blank group,uterine bleeding amount in model group was significantly increased(P<0.01),TXA2 content in se-rum was significantly reduced,PGI2 and TNF-α contents were significantly increased(P<0.01). Compared with model group,uter-ine bleeding amounts in administration groups were significantly reduced,TXA2 content in serum was significantly increased(P<0.01);PGI2 and TNF-α contents in serum in Gongxuening capsule group and C. cristata n-butanol extracts high-dose group and TNF-α content in serum in C. cristata n-butanol extracts medium-dose group were significantly reduced (P<0.01). CONCLU-SIONS:C. cristata n-butanol extracts show obvious improvement effect on incomplete drug abortion-induced dysfunctional uterine bleeding of rats,and the mechanism may be related to the regulation of TXA2/PGI2 dynamic balance and inhibition of TNF-α tran-sient secretion.

Pan-colonic motility was studied under normal conditions with a novel capsule-style system. A single use telemetry capsule embedded with one pressure sensor was ingested by subjects. It is capable of transmitting colonic pressure wirelessly greater than 130 h. Time of capsule entering segmental colon was determined by ultrasonic detection for tracing the batteries in capsule. The ultrasonic electrodes were mounted on the surface of subjects' ileocecum, navel as well as the junction of left colon and rectosigmoid colon in sequence. They were identified by abdominal X-rays with radiopaque markers. The confirming X-rays showed all telemetry capsules were detected successfully when passing through the key points in colon. A total of 613 h of colorectal recording was obtained from 20 healthy subjects. When compared with the parameters in the time of waking, the number of contractions and the area under contractions were significantly (P<0.05) decreased during sleep (21 +/- 5 vs 15 +/- 4 h(-1); 463 +/- 54 vs 342 +/- 45 mmHg x s x min(-1)). The colonic motility exhibited significant regional variation in the circadian behavior, as well as in its response to waking and meal. The clinical study proved the reliability and non-invasiveness of the system. It may represent a useful tool for the study on physiology and pathology of colonic motor disorders.
