1.Study on the representation and encoding of Chinese characters in DICOM
Chinese Medical Equipment Journal 1989;0(04):-
Character Repertoires are supported by DICOM to encode Characters in different languages, in which UTF-8 and GB18030 are for Chinese characters. Each of them can replace Acquiesced Character Repertoire in Attribute Specific Character Set so that Chinese characters can be encoded in data elements. Utility programs compatible with DICOM are also required to support UTF-8 or GB 18030 for unerring representation and encoding.
2.Safety location of bony tunnel in coraco-clavicular ligament reconstruction: a digital anatomical study
Chinese Journal of Orthopaedic Trauma 2014;16(4):329-333
Objective To determine the safety location of the bony tunnel in reconstruction of the coracoclavicular ligaments on the basis of digital characterization of the anatomy of the clavicle and coracoid process.Methods Unilateral shoulder spiral CT scan was conducted in 30 patients without injury to the clavicle or coracoid process.They were 15 men and 15 women,aged from 20 to 71 years old (average,49.3 years).Thirty 3D digital models of the clavicle and coracoid process were constructed using the CT scan data by Mimics13.0.Half of the models were of the left shoulder and half of the right.Anatomic measurements of the clavicle and coracoid process were carried out on these models.Virtual transclavicular-transcoracoid bony tunnels were established according to the anatomy of the conoid ligament.Parameters of these bony tunnels were measured before the safety location was calculated.Results The mean clavicular length was 147.70 ± 5.34 mm in males and 133.09 ± 6.61 mm in females; the distance between the lateral edge of the clavicle and the center of the conoid tuberosity (CCD) was 35.90 ± 3.16 mm in males and 30.48 ± 0.54 mm in females; the distance between the lateral edge of the clavicle and the center of the trapezoid tuberosity (CTD) was 22.68 ± 1.23 mm in males and 18.69 ± 1.65 mm in females,with significant differences between genders (P < 0.05).There were no significant differences between male and female regarding the ratio of the CCD to the clavicular length,the ratio of CTD to the clavicular length,or the mean internal rotational angle of the coracoid process (P > 0.05).According the attachments of the conoid ligament on the clavicle and coracoid,from the superior-posterior edge of the clavicle to the anterior midpoint of the coracoid basement,the bony tunnels were established.These tunnels nearly bisected the cross section of the clavicle and coracoid basement,35.23° ± 2.36° medially inclined to the sagittal section and 5.91° ± 2.14° posteriorly inclined to the coronal section of the body.Conclusions To ensure that the bony tunnel should pass through the center of the clavicle and coracoid,it should be drilled from the superior-posterior edge of the clavicle and located at the clavicular attachment of the conoid ligament,tilting about 35° medially and 6° posteriorly to aim at the anterior midpoint of the coracoid basement.

Objective To investigate the effects of atorvastutin on the levels of plasm imflammation markers (hs - CRP, MMP - 3, TNF - α) and intima - media thickness(ITM) of the common carotid artery in patient with hyperlipidemic and atherosclerosis. Methods Fifty patient with hyperlipidemic and atherosclerosis were treated with atorvastatin (10mg qd) for 12 weeks. The levels of TC, TG, LDL -C, HDL -C, hs -CRP, TNF -α and MMP -3 were detected with radioimmmuneassay and eolorimetric methods. Color Doppler echo-cardiography was used to measure intima -media thickness(ITM) of the common carotid artery after 6 weeks and 12 weeks. Results TC, TG, LDL -C, hs -CRP, TNF -α and MMP -3 were decreased significantly(P < 0.01)after 12 weeks. IMT was decreased signifi-cantly(P < 0.05) and HDL - C was increased significantly (P < 0.05) after 12 weeks. Conclusion Atorvastatin could be effective in re-ducing blood - fat and anti - inflammatory action , regulating blood vessel endothelium (BVE) function and reversing structural chan-ges in IMT of the common carotid artery.

BACKGROUND:Coracoclavicular ligament reconstruction with transclavicular-transcoracoid driling is an effective surgical technique to treat acromioclavicular dislocation. A good driling in the clavicle leads to a perfect bony tunnel and a good surgery. OBJECTIVE: To observe the effects of different driling positions of the clavicle on the location of bony tunnels in coracoclavicular ligament reconstruction. METHODS:Sixty three-dimensional digital models of the clavicle and coracoid process were constructed by Mimics13.0. Virtual transclavicular-transcoracoid bony tunnels were established according to different surgical planes with different driling positions in the clavicle. Parameters of these bony tunnels were measured, and the safety was evaluated. Option 1: The driling was made 30 mm distal to the clavicle, located in the center of the front and rear edges of the clavicle surface. Option 2: The driling was made 40 mm distal to the clavicle, located in the center of the front and rear edges of the clavicle surface. Option 3: The driling was made at the straight line of tapered nodule tip and the midpoint of the base of the coracoid process, located at the rear edge of the clavicle upper surface. RESULTS AND CONCLUSION: Bony tunnels in option 1 were extremely on the inside of the coracoid. Bony tunnels in options 1 and 2 were not in the center of clavicle. Bony tunnels in option 3 were in the center of both clavicle and coracoid. The method of locating the driling position with a certain distance to the distal clavicle leads to different results in man’s and woman’s models. To ensure that the bony tunnel can pass through the center of clavicle and coracoid, it is suggested to dril at the straight line of tapered nodule tip and the midpoint of the base of the coracoid process and nearby the rear edge of the clavicle upper surface.

Baculovirus has many advantages as vectors for gene transfer. We demonstrated that recombinant baculovirus vectors expressing p35 (Ac-CMV-p35) and eGFP (Ac-CMV-GFP) could be transduced into human kidney 293 cells efficiently. The level of transgene expression was viral dose dependent and high-level expression of the target gene could be achieved under the heterogonous promoter. MTT assay suggested that both Ac-CMV-p35 and Ac-CMV-GFP did not have cytotoxic effect on human embryo kidney 293 cells. Cell growth curve showed the Ac-CMV-p35 and Ac- CMV-GFP transduced and non-transduced cells had similar proliferation rate, so baculovirus-mediated p35expression had no adverse effect on cell proliferation. In addition, baculovirus-mediated p35 gene expression protected human embryo kidney 293 cells against apoptosis induced by various apoptosis inducers such as Actinomycin D, UV or serum-free media. These results suggested that the baculovirus vector mediated p35 gene expression was functional and it could be widely used in molecular research and even gene therapy.
