Purpose To investigate the feasibility of 30 ml low-dose contrast medium in reducing the accumulation of contrast medium in venous system while maintaining enough artery enhancement in 256-slice CT angiography (CTA) of intracranial and cervical arteries.Materials and Methods Sixty patients with head and neck CTA were recruited prospectively,and they were randomly divided into group A and group B.The scan parameters of the two groups were identical,but the protocol of contrast medium injection was different.Group A was injected 60 ml contrast medium and 30 ml saline successively with the rate of 4.0 ml/s.Group B was injected 30 ml contrast medium and 50 ml saline successively with the rate of 5.0 ml/s.CT attenuation values of aortic arch,common carotid artery,subclavian artery,cerebral middle artery,superior vena cava,innominate vein,subclavian vein,internal jugular vein were measured,and the image quality was evaluated.Results The average CT values of superior vena cava,right innominate vein,right subclavian vein in two groups had significant differences (P＜0.05).The average CT values of left brachial vein,left subclavian vein,left and right internal jugular vein in two groups had no significant differences (P＞0.05).The average CT values of aortic arch,left and right common carotid artery,left and right subclavian artery,left and right cerebral middle artery in two groups had significant differences (P＜0.05).The scores of image quality in two groups also had significant difference (P＜0.05).Conclusion Head-and-neck CTA with 30 ml low-dose contrast medium is feasible and the images are satisfactory for diagnosis,which can reduce the dose of contrast medium and accumulation of contrast medium in venous system,while maintaining enough artery enhancement.

BACKGROUNDKAI1 is a new identified metastasis-suppressor gene whose expression in many types of tumors has been reported. The aim of study is to investigate the role of KAI1 protein in development of lung cancer and its values in predicting the prognosis of lung cancer.

METHODSThe expressions of KAI1 protein were detected in benign pulmonary disease tissue, precancerous disease tissue, lung cancer tissue and metastatic lung cancer tissue in local lymph node using tissue microarray and immunohistochemical method. The relationship between expression of KAI1 protein and clinicopathological parameters of patients with lung cancer was analyzed by Chi-Square test and Fisher exact test.

RESULTSThe positive rate of KAI1 expression was 100.0% in 10 cases of benign pulmonary diseases, 66.7% in 12 cases of precancerous diseases, 24.7% in 89 cases of primary lung cancer and 0 in metastatic lung cancer tissue in local lymph node respectively. The KAI1 protein expression in primary lung cancer tissues had no remarkable relationship with age and gender of the patients and the location of cancer, but had significant relationship with the histological type and differentiated degree of tumor, P-TNM stages and lymph node metastatic status.

CONCLUSIONSThe abnormal expression of KAI1 protein may participate in malignant progression of lung cancer. Its downregulation may promote the invasion and metastasis of tumor cell. Detection of the expression of KAI1 protein may be helpful to predict the prognosis of lung cancer.

Objective To explore the application value of triggered angiography non-contrast enhanced (TRANCE) technology in diagnosing lower limb arterial occlusive disease.Methods Totally 22 lower limb arterial occlusive disease patients were randomly selected,and then underwent TRANCE and DSA examinations.The arteries from the abdomen to the lower limb were divided into abdominal aorta,common iliac artery,external iliac artery,internal iliac artery,superficial femoral artery,deep femoral artery,popliteal artery,anterior tibial artery,posterior tibial artery and peroneal artery.Totally 337 sections displayed clearly were chosen to go through examinations by TRANCE and DSA.Results Of the 337 sections there were 312 ones with the same stenoses found by TRANCE and DSA,TRANCE found 16 sections with worse stenoses and 9 milder ones than by DSA.There were 153 sections with the same moderate stenoses (≥50％) displayed by TRANCE and DSA;Of the 153 sections,there were 15 ones with worse stenoses and 6 ones with milder stenoses found by TRANCE than by DSA.Kappa value of the two methods was 0.905.Conclusion TRANCE technology is a non-invasive,safe and nonradiative diagnosing method for the lower limb arterial occlusive disease.

Objective To investigate the relationship between peripheral inflammatory cytokines and anxiety symptoms in patients with the first?episode generalized anxiety disorder. Methods 48 patients diagnosed with the first?episode generalized anxiety disorder according to ICD?10 criteria and 48 healthy sub?jects were recruited. Peripheral levels of IL?1, IL?2, IL?4, IL?5, IL?6, IL?8, IL?10, IL?12p70, GM?CSF and IFN?γ of both groups were evaluated by enzyme?linked immunosorbent assay ( ELISA) ,and CRP was evalua?ted by immunoturbidimetric method. Generalized Anxiety Disorder Scale( GAD?7) and State?Trait Anxiety Inventory ( STAI ) were used to assess the levels of overall anxiety, state anxiety and trait anxiety. Results The levels of CRP ( ( 1. 19 ± 0. 80 ) mg/L vs ( 0. 68 ± 0. 70 ) mg/L, t=3. 31 ) , IL?1α( ( 70. 34 ± 3.60)pg/ml vs (16.94±3.42)pg/ml, t=74.50),IL?2((7.25±3.42)pg/ml vs (4.95±2.31)pg/ml, t=3.85), IL?4((102.02±73.14)pg/ml vs (75.55±32.78)pg/ml, t=2.29),IL?6((12.55±2.37)pg/ml vs (2.71±1.35) pg/ml, t=14.79),IL?8((44.64±16.21)pg/ml vs (35.69±11.70)pg/ml, t=3.10),IL?12((18.16±24.17) pg/ml vs (10.82±4.72)pg/ml, t=2.06),IFN?γ((23.32±15.52)pg/ml vs (16.48±6.80)pg/ml, t=2.79), GM?CSF((19.07±11.12)pg/ml vs (13.40±8.54)pg/ml, t=2.80) in patients with the first?episode general?ized anxiety disorder were significantly higher than normal controls(P<0.05) . Both SAI and TAI had signifi? cantly positive correlation with the levels of IL?1α, IL?2, IL?6, IL?8, IL?12, IFN?γ and GM?CSF ( r=0.24?0.76, P<0.05) . Conclusion The levels of some peripheral inflammatory cytokines in patients with the first?episode generalized anxiety disorder are significantly increased,and they have positive correlation with gener?al anxiety,state anxiety and trait anxiety,which may suggest some immune system defects in the patients.

Objective: To study the prevalence, clinical and genetic characteristics of primary carnitine deficiency (PCD). Methods: From January 2013 to December 2017, 720 667 newborns and their mothers were tested for PCD by tandem mass spectrometry. Potential mutations of carnitine transporter gene SLC22A5 among suspected PCD patients were analyzed. Dietary guidance and L-carnitine supplementation were provided to the parents. Growth and intelligence development were surveyed during follow-up. Results: In total 21 neonates and 6 mothers were diagnosed with PCD, which yielded an incidence of 1 in 34 317. Eighteen SLC22A5 mutations were detected, which included 4 novel mutations, namely c. 1484T>C, c. 394-1G>T, c. 431T>C and c. 265-266insGGCTCGCCACC. Eighteen patients were found to carry compound heterozygous mutations and 3 have carried homozygous SLC22A5 mutations. Three mothers carried compound heterozygous mutations and 2 carried homozygous mutations. Common mutations included c. 1400C>G (42.3%), c. 760C>T (11.5%) and c. 51C>G (7.7%). During the 8 ~ 42 month follow-up, neonates with PCD showed no clinical symptoms but normal growth. Blood level of free carnitine was raised in all mothers after the treatment. Conclusion The incidence of neonatal PCD in Henan is 1 in 34 317, with the most common mutation being c. 1400C>G. Above finding has enriched the spectrum of SLC22A5 gene mutations.

Objective To establish nasopharyngeal carcinoma cell line (CNE1) with eIF1 gene stable over-expression and to study its effects on the proliferation and migration of nasopharyngeal carcinoma cells.Methods EIF1 over-expression vector was constructed by adopting the pEGFPC1 eukaryotic expression system for transfecting nasopharyngeal carcinoma CNE1 cells.Thus the stably transfected EIF1-elF1 and its control cells were obtained.The over-expression situation of eIF1 in these cells was verified by real time fluorescence quantitative PCR(qPCR) and Western blot.The proliferation and migration activity of CNE1-eIF1 cells were tested by adopting the cell proliferation and migration tests.Results The enzyme digestion electrophoresis identification and sequencing showed that the pEGFPC1-eIF1 eukaryotic expression vector was successfully constructed.After mRNA and protein expression identification,compared with the reloading plasmid transfection group,the eIF1 gene mRNA and protein expression levels in nasopharyngeal carcinoma cell line CNE1 stably over-expressing eIF1 were up-regulated by 2.85 folds and 2.58 folds respectively (P＜ 0.05),while its proliferation and migration activities were down-regulated by 55 ％ and 36 ％ respective (P＜ 0.05).Conclusion The nasopharyngeal carcinoma cell line over-expressing elF1 is successfully constructed,the eIF 1 over-expression could significantly down-regulate the proliferation and migration activities of nasopharyngeal carcinoma cells,suggesting that eIF1 has potential anti-tumor effect.
