Computed tomography colonography (CTC) is a well-established technique for evaluation of colorectal cancer (CRC). Signiifcant advances have been made in the technique of CTC since its inception. Besides being an excellent tool for detection of CRC, it is minimally invasive, less time-consuming and well tolerated by patients. Furthermore, it has fewer complications than conventional colonoscopy (CC) or barium enema (BE). The application of new technologies, such as electronic cleansing (EC) and dual-energy CT (DECT), enriches the examination of CTC. In 2005, a standardized reporting scheme, CT colonography reporting and data system (C-RADS), was put forward by the working group on virtual colonoscopy. They proposed that the report should include lesion size, number, morphology, location, attenuation and recommendations for lesion surveillance. New research progress and clinical applications of CTC in CRC are reviewed in this article. In addition, the paper also brielfy touches upon technique, indications, contraindications, safety and risk of CTC.

Objective To study the relationship between needle retaining anddeqi. Methods Manual acupuncture was performed at the left ST36 of 26 naive healthy adult volunteers. Half of them retained the needles for 6 min and others were put the needle out immediately afterdeqi. Hemodynamic parameters of the anterior tibial artery were observed with color Doppler ultrasonography before and at 0, 1, 2, 3, 4, 5 min after acupuncture. Results There was significant difference in Vmax、Vm、Pi and Dist in anterior tibial artery before and 3 min after acupuncture, but wasn't between needle remaining and not. Conclusion Needle retaining cannot change the regional haemodynamics during acupuncture, which suggest it cannot strengthendeqi.

Stroke is common clinically and spasticity is one of the main symptoms.There is some advance in recognition of the spasticity after stroke in the basic and clinic,but it remains obscure.

Objective To study physiological foundation of acupunctureDeqi.Methods 28 healthy volunteers who never experienced acupuncture were recruited. The right Zusanli (ST36) and a site 1.5 cm beside Zusanli (ST36) (nominated as A) were acupunctured at different time. Shallow and deep acupuncturing was inserted at Zusanli (ST36). Only deep acupuncturing was inserted at A. Hemodynamic parameters of the anterior tibial artery including the peak value in the systolic phase (Vmax), the average blood flow velocity (Vm), and the inner diameter of vessels (Dist) were observed with colored Doppler ultrasound before, at the end of acupuncture, and 3 min afterDeqi response. Results There was significant difference in those parameters between before acupuncture and 3 min after deqi response when deep acupuncturing at Zusanli (ST36) (P＜0.05), but was not significant difference when shallow acupuncturing (P＞0.05). There was significant difference in ΔVmax and ΔVm between acupuncture at Zusanli (ST36) and A points (P＜0.05). Conclusion Arterial haemodynamics variation seems to be associated with acupunctureDeqi.

Objective To observe the effects of electroacupuncture at Zusanli (ST36) on lower limbs motor function in patients with stroke. Methods 63 patients were evenly randomized into electroacupuncture group and control group. All the patients received routine rehabilitation training and at the same time,patients in electroacupuncture group, received electroacupuncture at zusanli (ST36). They were assessed with Fugl-Meyer Assessment (lower limb, hip, knee and ankle), gait analysis (gait frequency, gait speed and step length of both sides) and lower limb Composite Spasm Scale (CSS) before and after treatment. Results The scores of Fugl-Meyer Measure, gait analysis, and CSS improved in both groups, and more significantly in electroacupuncture group. Conclusion Electroacupuncture at zusanli (ST36) can significantly improved lower limb motor function without worsening the spasm.

Objective To explore the potential connection between sympathetic response, heart rate and blood pressure modulation after caloric irrigation in order to study the role of vestibular stimuli in cardiovascular control. Method Efferent splanchnic nerve firing rates, ECG and blood pressure were recorded simultaneously during caloric stimuli on intact anesthetized(CON) rats(n=5), sinoaortic denervated (SAD)rats(n=5) and bilateral vestibular destroyed (VD) rats(n=5). Result It was found that after caloric stimulation with ice water mean blood pressure CON rats with intact reflex became lower and the mean heart rates became slower, splanchnic sympathetic nerve activities increased for a moment and then dropped significantly. SAD rats had significant stronger splanchnic sympathetic nerve activities VD rats after caloric stimulation, and their blood pressures changed to apposite directions. The coupled respiratory component on splanhnic sympathetic nerve activities were strongly affected by the caloric stimulation. Conclusion It is suggested that semicircular canal stimulation participate at least in the short-term blood pressure control mechanism and the role of central nervous system on respiratory drive may also be involved. Baro-reflex and vestibular afferent may play different role in the control of blood pressure they may work synergically in some physiological control processed.

Objective To evaluate the relationship between echocardiographic epicardial adipose tissue thickness(EAT) and the presence and severity of coronary artery disease(CAD). Methods One hundredand forty-seven patients (101 patients with CAD and 46 patients with normal coronary arteries by diagnostic coronary angiography) were enrolled. EAT thickness was measured using 2-D echocardiographic parasternal long-and short-axis views. EAT thickness measurements were compared with angiographic findings. Results EAT was significantly higher in CAD group comparison to control group [(7.41 ± 1.63)mm vs (4.41±1.60) mm, P ＜0.01 ]. Furthermore, EAT increased with the severity of CAD [(8.53 ± 1.00)mm vs (6.36 ±1.73)mm, P ＜0.01]. Gensini's score significantly correlated with EAT (r = 0.71, P ＜0.01 ). EAT thickness ≥5.35 mm had 87.13% sensitivity and 80.42% specificity (ROC area 0. 89, P = 0.01,95% CI [0.84 - 0.9;]) for predicting CAD. Conclusions EAT thickness, which is easily and non-invasively evaluated by transthoracic echocardiography, can be an adjunctive marker to classical risk factors for the prediction of CAD, it was significantly correlated with the severity of coronary artery disease.

A 33-year-old male patient with tick-borne encephalitis (TBE) was reviewed, who presented with severe neurological deficits following TBEV infection, and improved in his motor and quality of life after an individualized rehabilitation.

Objective To explore the association of serum bilirubin level at the time of admission with the compos?ite outcome（disability or death）in discharged patients with acute ischemic stroke. Methods In a retrospective cohortstudy from June 1st 2009 to May 31st 2012, we continuously included 3151 patients with acute ischemic stroke and col?lected demography,lifestyle,clinical manifestations and laboratory test data. Functional outcome was measured with themodified Rankin scale (mRS) when subjects were discharged. Disability was defined as mRS≥3 and composite outcomewas defined as mRS≥3 or death. Serum bilirubin was divided into four groups according to the quartile. Multiple Coxregression analysis was used to assess the independent relation between serum bilirubin and disability death and the com?posite outcome. Results There were 407 disabled patients，the disability rate was 12.9%；and 104 patients were dead，the fatality rate was 3.3%.After adjusting for multiple factors, we found the risks of composite outcome with total bilirubin in the four quartile were higher than that in the first quartile, aHR and 95%CI were 1.335(1.047～1.702) respectively；The risks of composite outcome with indirect bilirubin in the four quartile were higher than that in the first quartile, aHR and 95%CI were 1.355(1.062～1.728) respectively; The risks of composite outcome with bilirubin direct in the third and the forth quartile were higher than that in the first quartile, aHR and 95% CI were11.403(1.089～1.807)and 1.431 (1.118～1.833) respectively.With the increase of total bilirubin，indirect bilirubin and direct bilirubin level，the compos?ite outcome of discharged patient was on the increase. Conclusions The study indicated that higher serum bilirubincould increase the risk of composite outcome in ischemic stroke patients, there was dose-response relationship ,and bili?rubin was a independent risk factor.
