Objective To observe the clinical characteristics and prognosis in children with high take -off coronary artery.Methods The clinical characteristics,laboratory examinations and prognosis were retrospectively ana-lyzed in 49 children with high take -off coronary artery who had been admitted to Beijing Children′s Hospital Affiliated to Capital Medical University from April 2009 to December 201 2.Results Among 49 medical records of children with high take -off coronary artery,34 cases were male and 1 5 cases were female,with a mean age of (9.28 ±4.42)years old,and the youngest patient was 1 3 months old,and the oldest patient was 1 7 years and 2 months old.The 64 -section multidetector CT angiography of all patients showed one or both coronary arteries originated from 1 .0 cm higher than the junction area of sinus and aorta,including 38 high take -off of the left coronary artery,7 high take -off of the right coronary artery and 4 high take -off of both coronary arteries.The chief complaints of the patients included chest pain (22 cases,44.90%),chest tightness(1 3 cases,26.53%),declining of exercise tolerance(7 cases,1 4.29%),fatigue (5 cases,1 0.20%),palpitation(3 cases,6.21 %),syncope(1 case,2.04%).Electrocardiogram(ECG)of those pa-tients showed ST -T changes,atrioventricular block,sinus tachycardia,pathological Q -wave,proiosystole and bundle branch block.Ultrasonic cardiogram(UCG)indicated 1 4 patients with the enlarged left ventricle,including 2 patients with ejection fraction lower than 60%.After 1 0 days hospitalization,the anesis of chest pain and chest tightness were significantly different statistically(P <0.05),but there was no significant difference in ECG and UCG.Thirty -nine out of 49 children were followed for 1 year.After 3 months,6 patients with ST -T problem showed normal ST -T segment. After 6 months,1 0 patients with ST -T problem showed normal ST -T segment.After 1 year,1 7 patients with ST -T problem showed normal ST -T segment.Conclusions High take -off coronary artery is a rare malformation of the coronary artery,which can cause myocardial ischemic,leading to multiple clinical manifestations and may result in ECG changes and the left ventricle enlargement.High take -off coronary artery can be confused with myocarditis and myocar-dial lesion clinically.Patients receiving systemic treatment may have their symptoms released,but ECG and UCG may not relieve in a short term.Patients with high take -off coronary artery need long -term observation.

Objective To evaluate the therapeutic efficacy of percutaneous drainage of solitary retroperitoneal abscess under CT guidance.Methods A retrospective analysis was made for percutaneous drainage of solitary retroperitoneal abscess with CT guidance in 13 patients including 4 at the tail of pancreas, 3 nearby the head of pancreas,3 in perirenal space,2 in posterior renal space and 1 case was by the side of psoas muscle.The maximum diameters of retroperitoneal abscess were between 3.5cm and 8cm.Results Out of 13 patients,8 with one time drainage,3 with twice drainages and 2 with thrice drainages.The mean duration of drainage was 16 days with no recurrence or residual lesions during clinical follow up.Conclusion CT guided percutaneous drainage of solitary retroperitoneal abscess is effective and minimally invasive.(J Intervent Radiol,2007,16:828-830)

Objective:To validate the clinical value of CT-guided curve-needle percutaneous ethanol injection (CNPEI) for celiac plexus block analgesia. Methods: Thirty-two patients with end-stage cancer, including 13 complicated with extensive retroperitoneal lymph node enlargement and fusion, were enrolled in this study. All patients complained of refractory upper abdominal pain and had received narcotic analgesics and radiotherapy, but the analgesic effect was not good. CT-guided CNPEI was therefore prescribed. Results: The effective rates of CT-guided CNPEI were 100%, 100%, 96.9%, 90.6%, 87.5%, and 84.4% immediately,and at 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 16 weeks after treatment, respectively. All enlarged lymph nodes had obvious necrosis and became shrunk. Conclusion: Combined application of bilateral anterior and posterior diaphragmatic crura block and trans-lymph node block can produce good analgesic effects, and curve-needle puncture make the above technique simpler.

Objective:To validate the therapeutic value of CT-guided percutaneous ethanol injection (PEI) in the treatment of metastatic adrenal tumors. Methods: Thirty-one foci (diameter ranging from 1.5 cm to 7.2 cm) in 25 patients with metastatic adrenal tumors were treated with CT-guided PEI for more than twice. Plain and enhanced CT scans were performed 1-2 months after PEI to observe the size and necrosis of the tumors. Results: Post-PEI enhanced CT scan showed that 18 of the 20 foci with diameters less than 3 cm completely necrotized; 11 foci with diameters between 3 cm and 7.2 cm necrotized partially, and 2 foci completely necrotized after another 2-3 courses of PEI treatment. Conclusion: CT-guided PEI is a simple and minimally invasive means for treatment of metastatic adrenal tumors, and the therapeutic effect is satisfactory.

Objective To address the neural basis of Chinese idioms processing with different kinds of stimuli using an event-related fMRI design.Methods Sixteen native Chinese speakers were asked to perform a semantic decision task during fMRI scanning.Three kinds of stimuli were used: Real idioms (Real-idiom condition);Literally plausible phrases (Pseudo-idiom condition,the last character of a real idiom was replaced by a character with similar meaning);Literally implausible strings (Non-idiom condition,the last character of a real idiom was replaced by a character with unrelated meaning).Reaction time and correct rate were recorded at the same time.Results The error rate was 2.6%,5.2% and 0.9% (F = 3.51,P0.05 )for real idioms,pseudo-idioms and wrong idioms, respectively.Similar neural network was activated in all of the three conditions.However,the right hippocampus was only activated in the real idiom condition,and significant activations were found in anterior portion of left inferior frontal gyrus (BA47)in real-and pseudo-idiom conditions,but not in non-idiom condition.Conclusion The right hippocampus plays a specific role in the particular wording of the Chinese idioms.And the left anterior inferior frontal gyms (BA47)may be engaged in the semantic processing of Chinese idioms.The results support the notion that there were specific neural bases for Chinese idioms processing.

Objective To determine if Shenfu injectio(SFI)has any analeptic action in patients emerging from general anesthesia.Methods Eighty-six ASAⅠorⅡadult patients undergoing elective abdominal surgery under general anesthesia were randomly divided into 2 groups(n=43 each):SFI group and control group.The patients were premedicated with intramuscular phenobarbital 0.1g and atropine 0.5mg.Anesthesia was induced with propofol 2 mg?kg~(-1),fentanyl 4-5?g?kg~(-1) and vecuronium 0.1 mg?kg~(-1) and maintained with propofol infusion(2-4 mg?kg~(-1)?h~(-1)),0.5%-1.0% isoflurane inhalation and intermittent i.v.boluses of fentanyl and vecuronium.The patients were intubated and mechanically ventilated.The propofol infusion and isoflurane inhalation were stopped during skin closure.The patients were still unconscious and on mechanical ventilation at the end of surgery and transferred to PACU with a tube in trachea.As soon as the patients reached the PACU,SFI 1 ml?kg~(-1) in Ringer's solution 100 ml was infused over 10 min.In control group the patients received Ringer's solution 100 ml without SFI.The following times were recorded:(1)the time when the patients opened their eyes on command;(2)the time when mechanical ventilation was stopped;(3)the time when oxygen inhalation was stopped;(4)the extubation time;(5)the time of staying in PACU.Venous blood samples were taken before(T_0) and 5,15 and 45 min(T_(1,2,3))after SFI infusion for determination of plasma?-endorphin concentration.Results The awakening time,the mechanical ventilation time,oxygen inhalation time,extubation time and duration of PACU stay were significantly shorter in SFI group than in control group.There were no significant differences in MAP and HR after SFI between the two groups.The plasma?-endorphin concentration was significantly higher in group SFI than in control group.Conclusion Shenfu injectio can make patients emerging from general anesthesia faster.

AIM:To compare the efficiency of fibrin glue to suture technique in pterygium surgery performed with limbal autograft under different methods of anesthesia.
METHODS: A prospective randomised clinical trial was carried out in 60 eyes of 55 patients operated for primary nasal pterygium, which were divided into two groups randomly: experimental group ( 30 eyes in 27 patients ) was under surface anesthesia ( oxybuprocaine ) and control group ( 30 eyes in 28 patients ) was under local anesthesia ( 20g/L lidocaine ). Autologous limbal graft taken from the superotemporal limbus was used to cover the sclera by a fibrin tissue adhesive after pterygium excision. Patients were followed up at least for 6mo. Time of operation, matching degree of graft and VAS score were mainly observed and recorded.
RESULTS: In experimental group the average surgery time was shorter (P=0. 008) and matching degree of graft ( 93%) was better than control group ( 83%) , the differences had statistical significance(P<0.05).
CONCLUSION: The surface anesthesia is enough when using fibrin glue for graft fixation in pterygium surgery, which will shorten surgery time and get better matching degree of graft.

Objective The present study was to explore association of PvuⅡand XbaⅠpolymorphism in ER-?gene with genetic susceptibility for breast cancer without BRCAl/2 gene mutation. Methods 113 BRCA1/2 negative hereditary breast cancer patients from independent families and 113 agematched healthy control subjects were analyzed. Genotype analysis was conducted by polymerase chain reaction (PCR) and then DNA direct sequencing. The odd-ratios (OR) and 95% confidence intervals (CI) was calculated by unconditional logistic regression model. Results The frequency of PvuⅡpolymorphism CC(PP) ,CT(Pp) ,TT(pp) genotype in patients was found in 16 cases(14.2% ), 58 cases(51. 3% ) , and 39 cases (34. 5% ). The distribution of AA (xx) , AG (Xx) , GG (XX) genotype of XbaⅠpolymorphism were found in 76 cases ( 67. 2% ) , 34 cases ( 30. 1% ), and 3 cases ( 2. 7% ) among patients. Among premenopausal women, CT genotype of PvuⅡconfered a significantly increased risk for breast cancer compared with CC genotype ( adjusted OR = 2. 07; 95% CI, 0. 68 - 6. 30) ; Carriers of GG of XbaⅠhad a decreased risk for breast cancer (adjusted OR =0. 11; 95 % CI, 0. 01 - 1. 27) compared with AA genotype. Furthermore, combined analysis of two polymorphisms indicated individuals carrying PvuⅡCT and XbaⅠAA genotype were at increased risk for breast cancer as compared with those with PvuⅡCC and XbaⅠGG genotype (Oft = 11.43, 95% CI, 1.12-116.7) among premenopausal women. Conclusions PvuⅡand XbaⅠpolymorphisms in ER-?gene could be a candidate locus for low penetrance breast cancer susceptibility in Chinese population, especially among premenopausal women.
