The notational DSA was first proposed for the application as a managing tool of neuronradiology in the early 70's of 20th centery.Later on,three dimensional image reconstruction(3D DSA) was aquired along with the progressing development of technique and equipment devices.As a rather practical instrument,it has been utilized successfully in the diagnosis and management of head and neck vascular disorders,and abdominal parenchymal diseases during recent years.We comprehensively intoduce the application of rotational DSA for the diagnosis and management in hepatic diseases.

Objective To investigate the correlation between the expression of CD147 and MUC5ac in peripheral small cell lung cancer and the computed tomography (CT) signs.Methods Forty two cases of peripheral non-small cell lung cancer (NSCLC) confirmed by operation and pathology were examined by CT.The positive expression of CD147 and MUC5ac was detected by immunohistochemical staining and the relationship between the expression of CD147 and MUC5ac was analyzed.Results CD147 and MUC5ac were closely related to the lymphatic metastasis of peripheral non-small cell lung cancer (P ＜ 0.05).The positive expression of CD147 is significantly related to tumor size,deep lobulation,spinous process and lymphadenopathy (P ＜ 0.05).MUC5ac is significantly related to tumor size,deep lobulation,spiculation,vascular convergence sign,extrapleural fat Line disappearance,and mediastinal lymphadenopathy (P ＜0.05).Conclusions These results indicate that CD147 and MUC5ac play an important role in the invasion and metastasis of peripheral lung cancer.

Objective:To assess the effect of auto-bone marrow mononuclear cells (BMMNCs) transplantation on reendothelialization and neointima formation in vein grafts. Methods: BMMNCs were extracted from the bone marrows of adult rabbit under sterile environment and were labelled with DAPI before transplanted into vein grafts. Twenty adult rabbits were randomly divided into 2 groups: BMMNCs transplantation group(groupⅠ,n=10) and PBS transplantation group (group Ⅱ, n=10). The left external jugular vein of 20 rabbits were harvested and transplanted between ipsolateral common carotid artery(AVG). Three days later, animals in group Ⅰ were transplanted with BMMNCs(6?108 cells)/100 ?l via periotic veins and those in groupⅡwere injected with 100 ?l PBS. Animals were killed 4 weeks later and graft veins were harvested to observe the reendothelialization and the thickness of vein grafts. Results: We found that the transplanted cells survived and were incorporated into the endothelium of vein grafts in groupⅠ.The endothelium integrity of the vein grafts in groupⅠwas significantly better than that of groupⅡ. The intima thickness of vein grafts in groupⅠwas significantly thicker than that of groupⅡ. Conclusion: BMMCs transplantation therapy may improve reendothelialization of the vein graft and inhibits intimal hyperplasi the vein graft.

Objective To study the effects of cinobufotalin capsule combined with transcatheter arterial chemoembolization in patients with hepatocellular carcinoma.Methods 68 patients with hepatocellular carcinoma from January,2013 to March,2016 were selected and divided into the combination group and chemotherapy group according to the random number table method,each with 34 cases.The combination group was treated with transcatheter arterial chemoembolization and hepatic artery infusion chemotherapy embolization.The levels of D-dimer,tumor markers,clinical efficacy and quality of life scores were observed before and after treatment in 68 patients.Results There was no significant difference in plasma fibrinogen(FIB)in combination group before and after treatment.Before treatment,the levels of FIB)was similar to chemotherapy group.After treatment,the FIB content in the chemotherapy group was significantly higher than before treatment and that in the combination group the differences were statistically significant(P<0.05).After treatment,the levels of cytokeratin 19,carcinoembryonic antigen and neuron-specific enolase in two group were significantly higher than those before treatment(P<0.05).But there was no significant difference between the two groups after treatment.The rate of disease control in the combination group was significantly higher than that in the chemotherapy group(77.5％vs.65.4％,P<0.05).Cases of diarrhea and insomnia in chemotherapy group were similar to the combination group,but the differences of cases of pain and fatigue between two group were statistically significant(P<0.05).Conclusion Cinobufotalin capsule combined with transcatheter arterial chemoembolization can improve the hypercoagulability of the patient's blood,and is beneficial to the treatment of cancer,improve the disease control rate and improve the life of patients.

Objective To investigate the microRNAs(miRNAs)expression profiles in the bowels of patients with Hirschsprung disease(HSCR),and to explore the role of differentially expressed miRNAs in the pathogenesis of HSCR. Methods Twenty - seven HSCR tissues,including spastic segments and distending segments,were obtained from patients with HSCR during operation. Then miRNA microarrays were used to investigate the miRNA expression profiles in 6 HSCR specimens. Bioinformatics software was used to predict target genes of miRNA. Three miRNAs (miR - 145 - 3p,miR - 4505 and miR - 1260a)were chosen and quantificational real - time(qRT)- PCR was per-formed to verify the different expression of those three miRNAs in 27 HSCR tissues. Results The expression of 26 miRNAs in an aganglionic colon segment was found to be more than two fold greater than that in ganglionic segment tis-sues,including 19 up - regulated miRNAs and 7 down - regulated miRNAs in patients with HSCR(all P ﹤ 0. 05). Tar-get genes of miRNAs were found,such as SOX10,RET,L1CAM. qRT - PCR showed the expression of miR - 145 - 3p (1. 42 ± 0. 42,aganglionic segment vs 0. 90 ± 0. 31,ganglionic segment)and miR - 4505(1. 30 ± 0. 30,aganglionic segment vs 0. 76 ± 0. 22,ganglionic segment)displayed a statistical difference between groups(all P ﹤ 0. 001). Be-sides,the expressions of miR - 145 - 3p(1. 53 ± 0. 46,long - segment type vs 1. 16 ± 0. 12,short - segment type)and miR - 4505(1. 42 ± 0. 26,long - segment type vs 1. 00 ± 0. 16,short - segment type)showed a statistical difference be-tween different types(all P ﹤ 0. 001),but miR - 1260a(1. 11 ± 0. 25,aganglionic segment vs 0. 99 ± 0. 21,ganglionic segment)did not show differential expression between different groups(P = 0. 064). Conclusions Abnormal expression of miRNAs was found in HSCR spastic segments,suggesting that miRNAs may be involved in the pathogenesis of HSCR.

Objective To compare different blood purification techniques on serum fibroblast growth factor 23(FGF -23)scavenging effect in patients undergoing maintenance hemodialysis (MHD),in order to choose the best blood purification method for clinical maintenance hemodialysis patients.Methods 60 MHD patients were randomly divided into hemodialysis group (HD),hemodiafiltration group (HDF)and HD +HP group,20 cases in each group. Three groups of patients in the observation 1st start of treatment and observation at the end of the last treatment were detected cacium,phosphorus,FGF -23,intact parathyroid hormone(iPTH).Results After treatment,HD group and HDF group,Ca:t =0.29,P =0.77;P:t =1.65,P =0.11;iPTH:t =16.85,P =0.00;HD group and HD +HP group:Ca:t =0.20,P =0.84;P:t =2.62,P =0.01;iPTH:t =42.64,P =0.00;HDF group and HD +HP group:Ca:t =0.09,P =0.92;P:t =2.18,P =0.04;iPTH:t =31.41,P =0.00.After treatment,FGF -23 in the three groups were decreased significantly than before treatment,and the HD +HP group decreased most significantly(HD group and HDF group,t =4.47,P =0.00;HD group and HD +HP group:t =8.06,P =0.00;HDF group and HD +HP group:t =3.20,P =0.00).Conclusion HD +HP treatment can effectively remove phosphorus maintenance dialysis patients and FGF -23.

Objective To describe the CT and MR imaging features of hepatic inflammatory myofibroblastic tumor(IMT).Methods The CT(n=12)and MRI(n=2)findings of pathologically proved hepatic IMT in 12 patients were retrospectively analyzed.Results All the tumors of the 12 patients were solitary and located in right hepatic lobe.Six tumors were solid and 4 tumors were solid-cystic.The other 2 tumors were periportal soft-tissue infiltration.The tumors appeared as solid or solid-cystic hypodense mass on CT images.The lesions were dark in T1-weighted sequences and slightly bright on T2-weighted sequences.There was homogeneous or inhomogeneous moderate to significant enhancement in solid portion of the tumors.Honeycomb-like enhancement was demontrated both in the peripheral part and at the intratumoral septa of the solid-cystic mass.Conclusion CT and MRI can provide helpful information for the clinical diagnosis and differential diagnosis of hepatic IMT.

Objective To explore the influencing factor of duration of untreated psychosis(DUP) and the relationship between duration of untreated psychosis and treatment outcome in epidemiological first-episode schizophrenia. Methods 912 medical records of the first episode schizophrenia patients were recruited in the study for epidemiological survey . The general medical data, clinical diagnosis, and treatment outcome were collected. DUP was determined refer to symptom onset for schizophrenia (SOS) scale. Patients were divided into short DUP and long DUP groups according to the median values of DUP values. Results Between short DUP and long DUP groups, the difference in marriage was significant ( P < 0. 05). The unmarried patients in the short DUP group (63.7% ) was higher than the long DUP group (52.6% ), the variance was significant (λ2 =5.990, P<0.05). The divorce in the short DUP group (0.6% ) was lower than the long DUP group (4.4% ) , the variance was significant (λ2 =5.079, P<0.01).The simple schizophrenia in the short DUP group (1.5%) was lower than the long DUP group (4. 1% ) , the variance was significant (λ2 =5.868, P<0.05). The treatment outcomes between the two groups had a significant variance ( λ2 =36.093, P < 0.01) , and the Ridit analysis of treatment outcomes between the two groups showed significant difference ( u = 5.183, P<0.01). The marriage,age of onset and clinical diagnosis were significantly correlated with DUP in multiple factor Logistic regression analysis. Conclusion The marriage,age of onset and clinical diagnosis are significantly correlated with DUP in the first episode schizophrenia patients,the longer of DUP and the worse of treatment outcome.
