Background & Objectives: Multiple sclerosis (MS), neuromyelitis optica (NMO) and acute transverse
myelitis (ATM) are common diseases in neurology; however their corresponding cervical spinal
cord involvements are still ambiguous. The purpose of this study was to demonstrate the utility of
diffusion tensor imaging (DTI) and diffusion tensor tractography (DTT) in identifying the injury in
cervical spinal cord. Methods: Nine patients and nine healthy volunteers were enrolled in this study.
Conventional sequences and DTI scan were performed on each participant. Results: The average
fractional anisotrophy (FA) values of the cervical cord in patients with acute cerebral type MS, acute or
stationary cerebrospinal type MS, acute NMO, or acute ATM were all significantly decreased relative
to the control group (p <0.05). As to the cerebrospinal type MS, the changes in acute-stage patients
were more apparent (p <0.05). The average FA value of the cervical cord in acute NMO was decreased
more extensively, involving the normal-appearing spinal cord (p <0.05). In patients with MS or NMO,
The lesions showed significantly hypointense on FA images and directionally encoded color (DEC)
images, nevertheless the pathological areas on DTI images were no significantly different from those
on routine sequences. On DTT, the fiber tracts in the lesion-involved regions were all sparser than
that in control regions, nevertheless interruption or impairment of fiber tracts could only be noted in
NMO patients. Bilateral differences of average FA values in the cervical cord was noted in one case
with ATM and another case with MS (p <0.05), and the decrease of FA values was significant in the
main side of clinical presentations.
Conclusion: DTI and DTT may be a sensitive measure for early cervical injury in MS, NMO and ATM

OBJECTIVETo investigate the application of intense pulsed light (IPL) depilation in the auricular reconstruction with totally expanded skin and its suitable parameter.
METHODSFrom February 2009 to September 2013, one tissue expander(100 or 150 milliliters) were implanted under the skin of mastoid in 126 patients who suffered from microtia. During the skin expanding, the hair on the expanded skin was depilated by JPL technique. The parameter, operation, interval, the depilation result and the complication were recorded. The autologous rib cartilage frameworks were implanted in the second phase of auricular reconstruction.
RESULTSThe energy of IPL was 20 - 35 J/cm2 (mean 25. 3 J/cm2), the width of pulse was 26 - 30 ms ( mean 27. 9 ms), the interval between two operations was 4 weeks. Ninety-six patients were cured(76. 2%, 96/126). The total depilation efficient is 96. 8% (122/126). A fine banding blisters was found in one patient whose depilation areas was marked by black pen. Skin erythema was found in five patients and skin pigmentation was found in 7 patients. There were no skin necrosis and expander exposure in all patients. During 6 - 12 months of follow-up period, ninety-two patients were cured (73.0%, 92/126) and the total depilation efficient is 92. 9% (117/126).
CONCLUSIONSIPL depilation during the skin expanding is feasible and safe with careful procedure. The hairless expanded skin is enough to cover the framework, as well as the post-auricular area. The appearance of reconstructed ear is better without hair.

Objective In order to improve the surgical treatment for midpiece esophageal carcinoma, different surgical ways were com-pared. Methods From January 2010 to June 2012, 110 patients with midpiece esophageal cancer in our hospital were divided into the Ivor-Lewis group (55 cases) and the Sweet group (55 cases) according to different surgical ways, that is to say Ivor-Lewis surgery via right chest and Sweet surgery through left chest. Length of specimens, rang of tumor invasion, distance of removal, incidence of residual carcinoma in the esophageal edges, number of lymph nodes removed in chest and abdomen, and positive rate of carcinoma infiltrated lymph nodes were compared between the two groups. Questions of surgical anatomy were investigated through questionnaire among surgeons of the two groups, and the scores of both groups were analysed. Results The length of resected specimens and number of lymph nodes removed in Ivor-Lewis group was significantly lager than that of the Sweet group (P<0. 01). The positive rate of carcinoma infiltrated lymph nodes in Ivor-Lewis group was 1. 82%, which was significantly lower than 21. 82% in the Sweet group (P<0. 01). Results of questionnaire showed surgeons have gieven higher scores to Ivor-Lewis group. Conclusion Ivor-Lewis surgery is recommend for upper and midpiece esophageal carcinoma while Sweet surgery is more suitable for cardial and lower esophageal cancer.

Objective To explore the effect of psychological rehabilitation on patients with limb motor dysfunction. Methods 136 cases of hospitalized patients who needed rehabilitation therapy and training were divided into observation group and control group. The control group received conventional rehabilitation, and the observation group received psychological rehabilitation (psychotherapy and medicine) in addition. Symptom Checklist-90 (SCL-90), Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) were assessed before and 8 weeks after treatment. Results Most of the 136 patients were involved in psychological problems, including anxiety, depression, somatization,fear, hostility. There was no difference in the scores of SCL-90, FMA and MBI between 2 groups before treatment (P>0.05). After 8 weeks treatment, the scores of SCL-90 were lower, except psychotism (P>0.05), in the observation group than in the control group (P<0.05),the scores of FMA and MBI were higher in the observation group than in the control group (P<0.01). Conclusion The psychological rehabilitation plays an important role in rehabilitation of limb motor dysfunction.

OBJECTIVE To explore the effect of gene therapy on the nasopharyngeal carcinoma (NPC) cell line CNE-2 by using the combination of TRAIL gene with hTERT promoter. METHODS Total RNA was ex-tracted from PBL (peripheral blood lymphocytes)whose proliferation had been stimulated. TRAIL gene with interleukin 2 signal peptide gene was amplified by RT-PCR and cloned into the vector pGL3-181hTE down-stream to the RT promoter to form an eukaryotic vector. The vector was transfected into CNE-2 cells and HL-7702 cells through lipofection. Flow cytometry (FCM), agarose gel electrophoresis and cell morphology were used to examine the cell apoptosis. RESULTS In tranfected nasopharyngeal carcinoma cells CNE-2, FCM analysis showed that apoptotic peak appeared before G1 phase. A ladder-like pattern of DNA fragmentation appeared upon agarose gel electrophoresis. Many cells exhibited apoptotic changes such as cell shrinkage , nulear condensation , and nuclear fragmenta-tion under transmission electron microscope (TEM). CONCLUSION The recombinant eukaryotic ex-pression vector for TRAIL gene driven by hTERT pro-moter was successfully constructed and shown to induced apoptosis in CNE-2 cells. The results suggest that TRAIL may be a promising target for gene therapy of NPC.

Objective To investigate the morphological factors related to the rupture of very small (≤3mm) anterior communicating artery (AComA) aneurysms, which provides basis for decision-making of whether or not taking intervention in very small un-ruptured AComA aneurysms. Methods (1) One hundred patients with primary AComA aneurysms, admitted to our hospital from January 2008 to June 2013, were enrolled; 84 AComA aneurysms were ruptured while 16 were un-ruptured; the morphological parameters of aneurysms were obtained by three-dimensional reconstruction with CT angiography (CTA) of the patients, and the clinical data and aneurysm morphological parameters were compared between the ruptured aneurysm group and the un-ruptured aneurysm group; multivariate Logistic regression was used to analyze the risk factors of small aneurysm rupture in the AComA, and receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of size ratio (SR) of maximum tumor depth to proximal carrier artery diameter in rupture of small aneurysms in the AComA. (2) Ninety-nine patients with primary AComA aneurysms, admitted to our hospital from June 2013 to January 2016, were enrolled; the parameters from the above analyses were applied to these patients to verify their predictive effectiveness. Results (1) Perpendicular height, AR value (Height/Neck), SR value and vessel angle were significantly different between ruptured aneurysm group and un-ruptured aneurysm group (P<0.05); multivariate Logistic analysis indicated that SR value was the independent risk factor of rupture of very small AComA aneurysms (OR=4.201, 95%CI: 1.175-15.019, P=0.012), and the lager the SR value, the higher the risk of rupture; ROC curve analysis revealed that the area under the curve was 0.699 with the optimal cut-off value being 0.9, and its diagnostic sensitivity, specificity and accuracy was 0.786, 0.625 and 0.760, respectively. (2) The SR value was then applied to the 99 patients, showing a stable predictive potential with sensitivity, specificity and accuracy of 0.676, 0.714 and 0.687, respectively. Conclusion SR value (≥0.9) is identified as independent morphological risk factor for rupture of very small AComA aneurysms; SR value is closely related to the state of aneurysms, which help make a better individualized and effective decision on the treatment of very small AComA aneurysms in clinic.

Objective:
To explore the electrocardiographic characteristics of patients with idiopathic ventricular arrhythmias (VAs) originating from different portions of distal great cardiac veins (DGCV).
Methods:
The study included 49 patients underwent successful RFCA of premature ventricular complex(PVCs)/ventricular tachycardia(VT) from different portions of the DGCV in our department from July 2009 to March 2016. The surface 12-lead electrocardiogram (ECG) and intraventricular ablation mapping features were analyzed. Patients were divided into four groups according to the mapping and ablation results: DGCV1(10 patients), DGCV2 (13 patients), proximalanterior interventricular vein (PAIV, 17 patients)and extend distal great cardiac vein (EDGCV, 9 patients). We analyzed the similarities and differences between surface 12-lead ECG of patients with PVCs/VT from different portions of DGCV, and compared with random chosen 290 patients with PVCs/VT from ventricular outflow tract and adjacent structure.
Results:
A positive R wave in inferior leads, a negative QS morphology in lead aVL and aVR were found among all groups. The different characteristics of surface 12-lead ECG of VAs originating from DGCV were as follows: (1)EDGCV patients demonstrated a positive R or r wave on lead Ⅰ(6/9) while a negative rS or qr wave was evidenced in other three groups (39/40). (2)A positive R pattern on lead V1, V5-V6 (11/13) was presented in patients of DGCV2 group; R (without S or s) wave on V1 (9/10), RS or Rs wave on V5-V6 were found in DGCV1 group; RS or rS wave was seen on lead V1, R(without S)wave in lead V5-V6 (25/26) were found in EDGCV and PAIV group and the amplification of R wave in EDGCV was higher than V1 of PAIV group.(3)Precordial lead transition zone was in front of V1 for DGCV1 and DGCV2 groups (23/23), within V1-V3 for EDGCV group, but on V2 or within V2-V3 for PAIV group.(4)Patients of DGCV1 and DGCV2 demonstrated a longer Pseudo delta wave time(PdW), intrinsicoid deflection time (IDT), significantly larger maximum deflection index (MDI) than those in PAIV and EDGCV groups (
