Objective To explore the clinical value of dual-source CT(DSCT) in the diagnosis of coronary artery disease by comparing the result of DSCT and coronary angiography(CAG).Methods From July 2009 to August 2010,36 patients with suspected coronary hear disease underwent both DSCT coronary angiography(DSCTCA) and selective GAG examination.The results of DSCT coronary angiography were compared with CAG which was the gold standard of diagnosing coronary disease.The sensitivity,specificity,positive and negative predictive value,and accuracy of DSCT were evaluated.Results 144 coronary arteries were well evaluated of 36 cases.The sensitivity,specificity,positive and negative predictive value,and accuracy of DSCT in the diagnosis of coronary hear disease were 100.00%,66.67%,93.75%,100.00% and 97.20% respectively by the number of patients;The McNemar test showed no significant difference between two methods( x2 =0.500,P >0.05 ) with a higher diagnosis concordance (Kapp =0.768,P <0.01).By detecting moderate to severe coronary artery stenosis,the sensitivity,specificity,positive and negative predictive value,accuracy were 95.24%,96.08%,90.91%,98.00%,95.83%,respectively.The McNemar test showed no significant difference between two methods(x2 =0.167,P >0.05) with a higher diagnosis concordance ( Kapp =0.899,P < 0.01 ).Conclusion DSCT has a diagnostic accuracy of coronary heart disease close to that CAG,especially in evaluating patients with moderate to severe coronary artery stenosis,it has high compliance and consistency with CAG.DSCT is a noninvasive,safe and reliable radiographic method.

Objective To summarize the experience of applying choledochoscopy, duodenoscopy and laparoscopy, one-stage suturing of common bile duct, to treat cholecystolithiasis and choledocholithiasis that failed to respond to ordinary endoscopic sphincterotomy (EST). Methods Retrospectively analyzed the clinical data of twenty-five pa-tients with choledocholithiasis complicated with cholecystolithiasis. 25 cases of failure to endoscopic stone extraction underwent LC and laparoscopic common bile duct exploration with primary suture of (BD) from June 2013 to June 2015. Results One patient was converted to laparotomy with small incision. The other one had residual stones and therefore underwent a second EST. After the treatment, two patients developed hyperamylasemia, which was cured by conservative therapy; One patient had bile leakage, which was treated by percutaneous drainage with no serious complications and death. No long-term complication was found in a portion of patients followed up until now. Conclusion In properly selected patients of duodenoscopy management-failed, synchronous treatment of combined application of three endoscopies in laparoscopic surgery with primary suture of (BD) is feasible, effective and safe.

Objective To evaluate the application value of dual-source CT coronary angiography in low tube voltage setting and the influence of heart rate on image quality and radiation doses.Methods 323 patients suspected of coronary artery disease received retrospective ECG-gating coronary angiography with dual-source CT scanner,who were divided into low tube voltage group (100 kVp,n =201) and conventional voltage group (120 kVp,E group,n =122).No beta-blockers were taken before CT scan.All patients in low tube voltage group were divided into four groups according to the heart rate (HR):group A,HR≤59 beats per minute (bpm),n =50; group B,60≤HR <69 bpm,n =64; group C,70≤HR <91bpm,n =62;group D,HR ≥ 91 bpm,n =25.All images were transferred to a workstation for further processing.The best R-R interval reconstruction images of all groups were evaluated.The value of pitch,CT volume dosage index(CTDIvol),dose length product(DLP) and effective dose(E)were recorded.The pitch,the score of imaging quality of coronary artery segments and the radiation dose were compared with One-Way ANOVA.The influence of heart rate on image quality and radiation doses of coronary artery was analyzed.Results The value of pitch in groups A-D was 0.24 ± 0.03,0.29 ± 0.04,0.33 ± 0.05,0.38 ± 0.06,respectively,with statistical difference (F =62.57,P < 0.05).The value of CTDIvol in groups A-E was (21.59±7.97),(20.24±6.03),(18.23±7.55),(18.14 ±5.75),(38.62±16.21)mGy,respectively,with statistical difference (F =85.16,P < 0.05).The value of E in group A-E was (5.31 ±2.18),(4.85 ±1.70),(4.49 ± 1.86),(4.37 ±1.50),(8.75 ± 4.07) mSv,respectively,with statistical difference(F =44.83,P < 0.05).The image score was (4.65 ±0.46),(4.55 ± 0.53),(4.55 ±0.53),(4.47 ±0.72),(4.66 ± 0.44) (F =1.89,P > 0.05).Conclusions No beta-blockers was taken before CT scan,and a high quality image could be acquired by using dual-source CT coronary angiography in low tube voltage setting(100 kVp).When the auto ECG-gating is selected,medium and low HR have little influences on radiation dose,while the radiation dose could be decreased significantly at higher HR,but the possibility to obtain the high quality image decreased.

Portal vein thrombosis (PVT) is one of the most common complications of liver cirrhosis. Due to coagulation disorder and the risk of bleeding in liver cirrhosis, there are many controversies over the treatment of liver cirrhosis with PVT in clinical practice. Common therapies for PVT include anticoagulant therapy, intervention, and thrombolysis. This article elaborates on the current status of the treatment of liver cirrhosis with PVT, in order to provide help for the development of standard and reasonable clinical treatment strategies.

Objective:
To explore the therapeutic value of interventional methods for hemorrhage caused by mandibular arteriovenous malformations.
Methods:
The clinical data of 7 patients (3 males and 4 females) with mandibular arteriovenous malformations treated by interventional therapy from January 2012 to January 2018 in the First Affiliated Hospital, Zhengzhou University were retrospectively analyzed. Of all patients, 4 patients suffered from sudden massive hemorrhage and 3 patients suffered from spontaneous repeated bleeding. The age ranged from 8.0 to 13.0 (10.6±1.7) years. Of the 7 patients, 3 underwent interventional embolization via arteries and veins, and 4 underwent embolization only via arteries. The embolic materials were polyvinyl alcohol granules and coils. The follow-up period was 9—18 months and the curative effect was observed.
Results:
Among the 7 patients, 4 cases of acute massive hemorrhage were effectively controlled after interventional operation, 3 cases of chronic bleeding disappeared after interventional operation. No recurrence of bleeding occurred during the follow-up period, only 1 patient presented with oral infection and gingival swelling and hyperplasia. The symptoms were effectively controlled after anti-infection and debridement. No severe complications occurred in all patients.
Conclusion
Interventional therapy for ateriovenous malformation with hemorrhage is effective, safe and feasible, which is worthy of clinical application.

Objective: To explore the value of nanoparticles (CN) in lateral cervical lymph node mapping in papillary thyroid carcinoma using carbon. Methods: Thyroid cancer patients with suspicious lymph node metastasis but without typical signs of metastatic disease from March 2016 to November 2017 in Fudan University Shanghai Cancer Center were prospectively included in the cohort. Neck dissection was performed in all patients (compartmentsⅡ-Ⅴ). Suspicious lateral lymph node metastasis was identified using pre-operative ultrasound or computed tomography. CN were used for lymph node mapping during surgery. Results: A total of 70 surgeries were performed in 67 patients, among which 57 were found to have lateral lymph node metastasis (81.4%). The median number of CN-dyed lateral lymph nodes was 6. Compartment IV had the highest number of CN-dyed positive lymph nodes as well as the highest rate of metastasis, followed by compartmentⅢ. In compartmentsⅢandⅣ, the incidence of lymph node metastasis was significantly higher in the CN-dyed group than in the CN-undyed group (P<0.001). When the final pathology of neck dissection was set as the gold standard, lateral CN-dyed lymph node biopsy was found to have a sensitivity of 86.0%; its negative predictive value was 61.9% and its overall accuracy was 88.6%. Conclusions:Injection of CN during surgery was a potential method of mapping lateral lymph nodes in papillary thyroid carcinoma. CompartmentⅢ-ⅣCN-dyed lymph node biopsy had a satisfactory sensitivity and thus, served as a reasonable range for lymph node biopsy.
