Radiotherapy alone and local excision combined with radiotherapy have been alternative treatments of early rectal carcinoma resection.Compared with radical surgery,both radiotherapy alone and local excision combined with radiotherapy can get satisfactory effect,and prevent the high rate of complications and adverse reactions,which will improve the quality of life for patients with rectal carcinoma and should be recommended.

In recent years,the basal and clinical research in gonadal dysgenesis has achieved great progress.Considerable literatures concerning the diagnosis and therapy of these diseases have been published.In this review,we analyzed and summarized some more instructive literatures for clinical practice,discussed the problems and defects in gonadal dysgenesis research in China,and proposed some suggestions.

During surgery and radiation therapy,demands for higher quality of quantification and visualization of cerebral vessels need to be met.Hence,automatic (or semi-automatic) extractions of accurate cerebral vessel information seem particularly important.This paper reviews the cerebral vessel segmentation methods used in recent years,including statistics-based segmentation,deformable model,multi-scale method,prior knowledgebased method,and so on.The methods are divided into the following three categories:voxel intensity based approach,vascular tubular structure based approach,and prior knowledge-based approach.

Podcast,a versatile web-based technology,has been widely employed in international nursing education.In China,however,it is only applied based on its video-related function.The other functions,such as subscribing,participating,mobile,and sharing learning option have not been fully exploited.The studies on application of podcast demonstrate that it can excite the learning interest,alleviate stress and anxiety,and enhance the preclinical educational experience.Moreover,it facilitates the self-study ability.Therefore the podcast is expected to be applied more widely in the domestic nursing education.

Objective　To investigate whether or not the antisense oligodeoxynucleotide (ODN) of vascular endothelial growth factor (VEGF) can supresses the protein expression of VEGF.Methods　SMMC 7721 is a cell line that expresses VEGF.Therefore the medium conditioned by SMMC 7721 stimulates proliferation of bovine aortic endothelial cell (BAEC).Synthesized antisense ODN complementary to one region of VEGF mRNA was added into the medium of SMMC 7721.The expression of VEGF and the stimulation effect of SMMC 7721 was then determined.Result　It was found that by means of inhibition of VEGF expression,the stimulation effect of SMMC 7721 was inhibited by the VEGF antisense ODN in a dose-dependent manner.At a dosage of 1,2.5,5,10μmol/L,the inhibition rate was 63.2%,82.4%,210% and 287.5%,respectively.Conclusion　It is promising that VEGF antisense ODN works as a new gene therapeutic modaliey for antiangiogenesis of HCC.

[Objective]To investigate the late results of pedicle screw system and cage fixation for lumbar broken isthmus spondylolisthesis.[Method]Totally 86 patients with broken isthmus spondylolisthesis were collected and analyzed from October 1996 to October 2002,they were all reduced and fixed with pedicle screw system and cage.Group 1,62 patients were put one cage in the interbody at an angle of 45 degree from posterior to anterior,while Group 2,24 patients were put two cages in the interbody vertically from posterior to anterior.The height of interbody and the most proximal interbody' s height were measured,the rate was calculated.These rate were acquired preoperatively,2 weeks postoperatively and follow-up period respectively.[Result]The follow-up period was 24~96 months,averaged 35 months.The excellent and good rates were 80.23 per cent,according to Nakai standard.Ninteen patients with one degree spondylolisthesis were reduced anatomically after surgery.Fifty-one patients with two degree spondylolisthesis were reduced anatomically except 5 patients with one degree spondylolisthesis left.Sixteen patients with three degree spondylolisthesis were reduced anatomically except 4 patients with one degree spondylolisthesis left.There were loss of spondylolisthesis reduction at follow-up period comparing with 2 weeks postoperatively in two groups.However there was no statistical significance between the two groups.[Conclusion]Lumbar spondylolisthesis should be treated with pedicle screw system and cage,which may decrease the complications such as broken screw and spondylolisthesis recurrency postoperatively.One piece of cage is enough to make interbody stable.It is also an ideal procedure for lumbar spondylolisthesis.

[Objective] To evaluate the efficiency of Halovest external immobilization on the treatment of traumatic cervical fracture or dislocation.[Method]From February 1997 to July 2005,129 patients with cervical fracture or dislocation were treated in our hospital;all the patients were divided into two groups randomly.First group: 70 patients were treated with Halo-vest traction,among them 31 patients were treated with Halo vest combined jacket orthosis;others were treated with Halo vests and surgery(anterior route approach 18 cases,posterior route approach 17 cases,4 patients operated by anterior and posterior approach).The second group: 59 patients were treated with skull traction.Among them 13 patients were treated with skull traction and orthosis,others were treated with skull traction and surgery(anterior route approach 22 cases,posterior route approach 20 cases,4 patients operated by anterior and posterior approach).[Result]All the patients were followed 6~48 months(average 12 months).There was no statistical significance in two groups with reduction of upper cervical spine fracture and dislocation.However on the reduction of lower cervical injury groups,the prognosis with Halo-vest is significantly better than the other group.And the time for bed rest was much less than the skull traction.All the patients' spinal cord function improved obviously after treatment.[Conclusion]Halo-vest external fixation is an easy and effective way to treat cervical injuries.It can improve the reduction of the cervical injuries and it's capability of reduction and maintenance are much better than skull traction.

The translation methods of culture-laded words in TCM formula titles were discussed and analyzed in light of three-dimensional transformations of Eco-Translatology. Translation evaluation criterion was adopted as the degree of three-dimensional transformations including linguistic dimension, cultural dimension and communicative dimension. This paper aimed to contribute to the translation study of TCM formula titles.

Objective To explore the effect of different processes on the contents of active ingredients in Rhizoma Corydalis. Methods Processes of vinegar-boiling, vinegar-frying and alcohol-frying were used to fresh corydalis, boiled corydalis and purchased corydalis. Then the method of extraction by ultrasound with water and by reflux with methanol were used to extract the sample. The contents of Protopine, Tetrahydropalmatine and Dehydrocorydaline in corydalis was determined by RP-HPLC. Agilent TC-C18 (25 mm?4.6 mm, 5 ?m) column was used at 35 ℃, with acetonitrile-0.1% phosphonic acid (pH 5.3 with triethylamine) (28∶72) as mobile phase. The flow rate was 1 mL/min and detection wavelength was set at 280 nm. Results In the sample extracted by water, the contents of active ingredients in processed products were higher than in corydalis. And in the sample extracted by methanol, it also has the tendency that the contents of active ingredients in processed products were higher than in corydalis. The content of Dehydrocorydaline in fresh corydalis which was processed by vinegar-boiling, vinegar-frying and alcohol- frying was high. The content of Tetrahydropalmatine in purchased corydalis which was processed by water-boiling at production place was high. Conclusion The method of determining active ingredients in Rhizoma Corydalis was established. It was convenient and the result was accurate. The process technology that fresh corydalis was boiled by water and then processed or fresh corydalis was processed in production place can be used.
