Objective To investigate the relationship between neurogenic bowel dysfunction (NBD) and substance P in rats suffering from spinal cord injury (SCI). Methods 60 male Sprague-Dawley rats, weighted (220±40) g, were randomly divided into three groups: sham group (n=20), normal group (n=20) and model group (n=20) and then were subdivided into subgroups of 24 h, 1 week, 3 weeks, and 5 weeks respectively after SCI. SCI model was established at thoracic 10 segment of rat with NYU impactor device. The colon tissue of the rats was resected and stored. Substance P in serum and tissue was measured by ELISA. The tissue was examined by real-time RT-PCR and Western blotting to analyze the expression of substance P. Results The colon intestinal transmission function decreased and delineated at minimum value at 3 weeks in the model group. There was statistical significance with respect to the content of substance P in serum and tissue between the sham group and model group at 3 weeks. The expression of substance P in the sham group was (3.12±0.51) times of the model group (P<0.05). Conclusion Substance P may take part in NBD after SCI in rats.

This study is to investigate protective effect of safflor yellow B (SYB) against vascular endothelial cells (VECs) injury induced by angiotensin-II (Ang-II). VECs were cultured and divided into six groups: control group, Ang-II group, Ang-II + SYB (1 micromolL(-1)) group, Ang-II + SYB (10 micromolL(-1)) group, Ang-II + SYB (100 micromolL(-1)) group and Ang- II + verapamil (10 micromolL(-1)) group. Except control group, all of VECs in other groups were treated with Ang- II at the final concentration of 0.1 micromolL(-1). Mitochondria membrane potential (MMP) and free calcium concentration ([Ca2+]i) were measured by laser scanning confocal microscopy, and mitochondria complex IV activity was detected by BCA method. The levels of reactive oxygen species (ROS) in VECs were analyzed by fluorescence detector and apoptosis of VECs was observed by flow cytometer. Caspase 3 was determined by Western blotting method. Comparing with control group, Ang-II was able to increase [Ca2+]i and ROS level, decrease MMP level, inhibit complex IV activity and enhance caspase 3 activity in VECs, as a result, enhance apoptosis of VECs. But SYB could significantly reduce the result induced by Ang- II relying on different dosages (P < 0.05 or P < 0.01). SYB was able to eliminate the effect of Ang-II on VECs via regulating [Ca2+]i, mitochondrial structure and function and inhibiting apoptosis.

OBJECTIVE To set up and evaluate the microscopic observation drug susceptibility assay(MODS)technology and use it to detect rapidly Mycobacterium tuberculosis(MTB).METHODS The 24-hole cell culture plate method of liquid culture were used to set up MODS technology.The MODS technology was used to detect MTB and non-M.tuberculosis(NMT)isolates comparing with Lowenstein-Jensen(L-J) method.RESULTS When bacterial concentration was 3?103 CFU/ml,the time of reading test-result was the seventh day by MODS;four kinds of NMT(M.phlei,M.kansasii,M.chelonaeand M.marinum) in the liquid medium in the observation was similar to the growth of cording,it was difficult to distinct from the cording of MTB in the liquid medium;When using the 4-Nitro-benzoic acid 800 ?g/ml,thiophene-2-carboxylic acid hydrazine 2.5 ?g/ml for testing conditions,the correct diagnosis can be improved;the test results of clinical isolates by MODS were highly concordance rate with the results of L-J.If the results of L-J was the golden standard,the sensitivity,specificity,positive and negative predictive value as well as accuracy by MODS was 95.7%,100%,100%,99.9% and 97% respectively.CONCLUSIONS The results of MODS in detection of MTB are highly concordance wih the results of L-J method;MODS assay can be used for rapid detection of tuberculosis,with a rapid,simple,inexpensive,and other advantages.
