Objective To explore the accuracy rate of classical anatomical landmark technique ( anterior , central , and posterior ap-proach) for internal jugular vein (IJV) by ultrasound technique.Methods Sixty-four patients with selective operation were included in this study.The anesthetist marked the anterior approach , central approach, and posterior approach for internal jugular vein at 0°(neu-ral), 30°,and 80°of head rotation, respectively.The accuracy of each anatomical landmark were examined by other anesthetist with ul -trasound technique .Results The accuracy rate of anterior approach and central approach were significantly higher than posterior ap -proach at 0°of head rotation, respectively.The accuracy rate of anterior approach was higher than posterior approach at 30°of head rota-tion.The accuracy rate was similar among anterior , central, and posterior approach at 80°of head rotation.Conclusion The accuracy rate was different in different approach of anatomical landmark for internal jugular vein .

Objective To explore the mental-behavior characteristics in serious internet game addicts.Methods To investigate internet addiction questionnaire, EPQ, social support questionnaire, purpose in life test and sensation seeking scale in 30 serious internet game addicts ( age from 16 ～ 25 years) and 43 non-addicts.Results Internet addicts have obviously lower social support questionnaire score, subjective support score, purpose in life test score and sensation seeking TAS score than non-addicts( P<0.05 or P<0.01 ). Objective support score, the use score for social support and sensation seeking score can forecast the internet addiction extent of the internet addict group. Internet addicts have obviously lower L score of EPQ than non-addicts ( P<0.01 ). There is the negative correlation between N score of the internet addicts and sensation seeking score( r=-0. 452, P<0.05). Conclusions Serious internet game addicts have the metal characteristics of low social support, low purpose in life and low adventure; sensation seeking and social support scale have prognosticative function for internet addiction degree; serious internet game addicts of low N score have high sensation seeking characteristic.

Thyroid cancer is one of common malignant tumor in neck, which can occur in any age. Females are more likely to have this disease than males. Most patients get a nodule on their thyroid, which typically does not cause any symptoms. Surgical resection is an effective method to cure thyroid cancer. In recent years, more and more evidence support that traditional Chinese medicine plays an important role in the recovery of postoperative thyroid carcinoma.

Chronic myeloid leukemia is a kind of malignant cloning hyperplastic disease of hematopoietic stem cell .The treatments based on molecular biological and immunological techniques will become the new therapies .Gene silence can improve the effects of molecular targeted therapeutic drugs through two ways: one is the target mRNA can be digested by siRNA and the other is target gene lose the stability and reduce the generation of protein mediated by miRNA .Adoptive cel-lular immunotherapy is a treatment method through injecting immunocompetent cells such as CIK , NK, etc into the body of cancerous person .This can improve the immunity of body and the effects of molecular targeted therapeutic drugs .The fur-ther study about basic theory , molecular mechanism and clinical effects will be continued .

Objective:To construct the helper virus VCSM13N1 with amber mutation,so as to provide a platform for the selective infective phage(SIP) technique.Methods: A pair of primers with amber stop codon were synthesized and introduced into N1 region of helper virus VCSM13 protein by overlapping extension PCR,and the products were identified by ristriction enzyme digestion and sequencing.The switch on/off efficiency of amber codon was detected with E.coli XL1-Blue and HB2151.The feasibility of using the amber mutant phage as helper virus was determined with anti-HBsAg phage antibody.Comprehensive analysis was also made on the performance of the amber mutant phage.Results: The titer of mutant phage was 2.5?10~(11) when detected with E.coli XL1-Blue,comparable with that of wild phage.The titer of mutant phage was at 10~6 level when E.coli HB2151 was used,being 10 000 folds lower than that of wild phage,when the mutant phages from HB2151 were used to infect E.coli XL1-Blue,the titer peaked at 5?10~(9),being 50 folds lower than that of wild phage.The activity of phage antibody prepared with mutant virus was comparable with the phage antibody prepared with wild phage.Conclusion: The constructed amber mutant phage can be used as helper virus,and it can switch off efficiently in non-suppressing strain HB2151.

Objective To investigate the anti-tumor effects of combined recombinant murine interleukin-12 and GM-CSF gene adenovirus vector(AdCMVIL-12,AdCMVGMCSF) on B16 melanoma.Methods B16 melanoma cells were injected subcutaneous at right back of C57/BL6 mice,48 tumor bearing mice were divided into 4 groups at random,when tumor diameter attained to 5 mm,AdCMVIL-12,AdCMVGM-CSF and AdCMVIL-12+AdCMVGM-CSF and AdCMVLacZ(control) were injected in different groups,tumor growth and immune responses of each group were tested,and the IL-12 and GMCSF levels in serum were observed.Results In combined group,necrosis, lymphocytes and macrophages were found in tumor tissues.30 d after treatment,the average volume in combined group was(60.73?11.36)mm~3, compared with AdCMVLacZ(control) group,and AdCMVIL-12 group,AdCMVGM-CSF group [(675.18?80.59),(186.91?19.15),(223.45?23.11)mm~3],there were significant differences(P
