The abnormal expression of gastrins and their receptors have close relationship with the occurrenceand the development of some colorectal neoplasms.The high expression of gastrins and their receptors promote colorectal neoplasms cell proliferation and inhibit apoptosis.The biological behavior is mainly rely on the abnormal expression of protein.Using differential proteomics can screen differential expression protein of high expression of gastrin-based colorectal neoplasms in the occurrence and development process,and then with the regulation of specific proteins to achieve the prevention and treatment of colorectal neoplasms purposes.

Primary and secondary prevention clinical trials have demonstrated that statins markedly reduced cardiovascular risks even in patients whose plasma level of low-density lipoprotein cholesterol is lower than that of drug-treatment goal in lipid management guidelines. The reasons are as follows: The "normal" level in guidelines is not the normal level biologically, it is merely an average value in a given human group; The composition of plasma lipids is very complex; Statins have effects other than lipid modifying. Statins should be prescribed in patients without hyperlipidemia but with risk factors or coronary heart disease.

This research is to investigate study the flavonoids from stems of Nelumbo nucifera and the cytotoxic activities of iso- lated compounds. The constituents were separated by column chromatography,and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for cytoxic activities by MTT method. Twelve compounds were isolated and identified as rhamnazin-3-O-beta-D-glucopyranoside (1), luteolin-3', 4'-dimethylether-7-O-beta-D-glucoside (2), kaempferol-3-O-beta-D-xylopyranosyl-(1-->2)-O-beta-D-glucopyranoside (3), quercetin-3,3'-di-O-beta-D-glucopyranoside (4), 1, 8-dihydroxy-3,7-dimethoxyxanthone (5), isorhamnetin-3-O-beta-D-glucopyranoside(6) , kaempferol(7), isorhamnetin (8), quercetin(9), astragalin(10), hyperoside (11) and 1-hy- droxy-3,7,8-trimethoxyxanthone(12). All compounds were isolated from stems of this plant for the first time, and compounds 1-5 were firstly isolated from the family nelumbonaceae. Compounds 24 and 6 showed significant cytotoxic activities against BEL-7402 carcinoma cell lines at a concentration of 1 x 10(-5) mol x L(-1) with the inhibitory rate of 67.36%, 53.25%, 57.78%, 60.13% and 52.11%, respectively.

The risk of stroke increases significantly after transient ischemic attack (TIA). TIA is an independent risk factor for cerebral infarction. This article review s the advances in prediction models of stroke risk after TIA in order to conduct rapid and accurate risk assessment and stratification in patients w ith TIA and develop timely reasonable treatment strategies, thereby reducing the risk of stroke.

Objective Evaluate the safety and efficacy of indwelling healer tube in prevention and cure the conglutination after the surgurey of flexor tendon tenosynovitis. Methods During the year of 2001～2006, We have 38 young patients treated with indwelling of healer tube into the local or partial of the recovering muscle and sinew, then anesthetic and sodium hyaluronate were injected in the tube in certain intervals to lubicate and prevent conglutination after the operations of joint of children flexor tendon tenosynovitis. Then let the young patients do some healing training attne earlystage after surgery. Groups of patient were set up to make comparative analysis and evaluate the effectiveness of indwelling of the healer tubes according to the recovery status of the function of arthrosis and grasp after surgery. Results The result is that the rate of choiceness of 46 sinew is 89.1% in 34 cases with indwelling healer tube after the observing period from 6 months to 2 years, whereas the other group of 44 sinew in 30 cases has the rate of choiceness of 63.6%. The comparison has the significant conclusion of statistics (P<0.05). Conclusion It is convenient and safe to use indwelling healer tube to prevent the conglutination after the operation of joint the broken finger muscle and sinew of children. Therefore it is worth popularizing and promoting.

Objective To evaluate the clinical outcome of lumbar spinal canal stenosis treated by microen-descopic discectomy. Methods The rear guard intervertebral discoscope was used to carry on unilateral or-bilateral "windowing" to relieve the dura mater spinalis and the nerve root oppression thoroughly. The "C" ann machine or laferal side photography position X was used for localization. Approximately 1.5 cm incision was made under local anesthesia or under the shallow epidural anaesthesia at posterior waist, the pathway tube was implanted after progressive expansion, part of lamina of vertebra was removed by drill, endoscope was inserted under the television surveillance to reveal removed lamina of verfebra, the proliferated cohesed articular process, the plump yellow ligament flava and the bulging intervertebral disc nucleus pulposus tis-sues, the nerve root canal was depressed, to relieve thoroughly its oppression, dura mater and nerve root. Results The follow-up continued from 5 months to 36 months. The evaluation with Nakai scale revealed ex-cellent in 168 cases, good in 9 cases, fair in 6 cases. The rate of good results was 96.7%. Conclusions Totally 183 cases were treated with this procedure posterior microendoscropie discectomy shows minimal inva-sion, less blood loss and quick recovery. The stability of lumbar spine can be reserved. It is safe and effec-tive for treating lumbar disc herniation complicated with spinal stenesis.

[Objective]To assess the influence of three-dimensional computed tomography (3D CT) reconstruction on preoperative fracture classification of intraarticular fractures by comparing 3D CT and 2D CT in preoperative fracture classification of tibial plateau fractures and acetabular fractures.[Method]A retrospective study was performed to evaluate 28 tibial plateau fractures and 19 acetabular fractures.Four attending traumatic orthopaedic surgeons used 3D CT and 2D CT respectively to evaluate fractures and rendered fracture classification.Test of agreement was performed to evaluate interobserver and intraobserver agreement about fracture classification.[Result]With the use of 3D CT images,interobserver and intraobserver reliability for fracture classification increased to perfect agreement.[Conclusion]3D CT could improve the reliability of preoperative fracture classification for tibial plateau fractures and acetabular fractures.3D CT is helpful and worthwhile for preoperative evaluation for fracture classification of intraarticular fractures.
