Objective:To analyze the magnetic resonance imaging (MRI) features of parasellar cavernous haemangioma and improve the diagnosis and differential diagnosis accuracy.Methods:13 patients with parasellar cavernous haemangioma were collected.All the patients were diagnosed by MRI and confirmed by pathology.Based on the pathologic findings,the MRI features were discussed.Results:9 cases presented horizontal dumbbell.The lesions located in the parasellar were larger than the sella turcica.The main body position of the lesions were centered lateral to the parasellar and encasesed the intracavernous internal carotid artery (ICICA).While,1 cases were similar in size and shape.1 case was located in the sella turcica.2 cases was centered lateral to the ICICA.pituitary were detected obscurity in 7 cases and displaced in 6 cases,6 cases appeared extremely high homogeneous intensity on T2-weighted images:as bright as cerebrospinal fluid signal.Only 5 cases underwent three-dimensional arterial spin labelling perfusion imaging (3D-ASL).The lesions revealed marked hypoperfusion.The cases of misdiagnosis were 9,including 4 cpituitary adenomas and 5 meningiomas.Conclusions:The characteristics of MR images ofparasellar cavernous haemangioma were horizontal bottle gourd form,the main body position of the lesions were centered lateral to the parasellar and encasesed the (ICICA),and their extremely high homogeneous intensity on T2-weighted images:as bright as cerebrospinal fluid signal.In cases that are equivocal,3D-ASL were useful in differentiating cavernous haemangiomas from parasellar meningiomas,which could decrease mistaken diagnosis.Graspping the imaging feature and differential diagnosis were helpful for the diagnosis of this disease.

OBJECTIVETo explore effects of Tongxinluo Capsule (TC) on platelet activating factor (PAF), vascular endothelial function, thrombolysis in myocardial infarction (TIMI) blood flow, and heart function in acute myocardial infarction (AMI) patients after delayed percutaneous coronary intervention (PCI).

METHODSTotally 80 AMI inpatients were recruited at Department of Cardiology, People's Hospital of Jiangxi Province, from Jan. 2008 to Sep.2013. Those in line with inclusion criteria were randomly assigned to TC treatment group and the conventional treatment group by random digit table, 40 in each group. Besides, another 40 healthy subjects from examinees at Outpatient Department were recruited as a healthy control group. PCI was performed after 1-week treatment. Then blood samples were collected, and then blood contents of CD62P, CD63, GP II b/III a, ET-1, NO, and plasma von Willebrand factor (vWF) levels were detected. Coronary TIMI blood flow and corrected TIMI frame count (CTFC) were determined during PCI. Meanwhile, noninvasive blood pressure (BP) and heart rate (HR) were recorded before and after PCI, and cardiac function measured. They were compared with the healty control group.

RESULTSCompared with the healthy control group, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 significantly increased, but NO significantly decreased in AMI patients (all P < 0.05). After 1-week intervention of TC, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, NO, and ET-1 significantly decreased (P < 0.05, P < 0.01). Compared with the conventional treatment group at the same time point, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 decreased more significantly in the TC group (P < 0.05, P < 0.01), increased NO levels were also more obviously seen (P < 0.01). The aforesaid parameters changed more obviously at day 30, as compared with those changes at week 1 (P < 0.05, P < 0.01). The TIMI blood flow grade and CTFC were more obviously improved after PCI in the two treatment groups. Better TIMI blood flow was seen in the TC group. TIMI level 3 blood flow rate was higher in the TC group than in the conventional treatment group with statistical difference (P < 0.05). The left ventricular ejective factor (LVEF) after PCI was obviously elevated in the TC group and the conventional treatment group (P < 0.01), and the improvement was more obviously seen in the TC group (P < 0.05). There were 6 cases of recurrent angina, 3 cases of ventricular tachycardial (VT)/ventricular fibrillation (VF), 6 cases of heart failure (HF), 1 case of cardiac sudden death in the conventional treatment group, with the total incidence of cardiovascular events being 40% (16/40). There were 2 cases of recurrent angina, 2 cases of VT/VF, 2 cases of HF, no cardiac sudden death in the TC treatment group, with the total incidence of cardiovascular events being 15% (6/40). There was statistical difference in the recurrent rate of cardiovascular events between the two groups (χ² = 2.27, P < 0.05).

CONCLUSIONTC not only could prevent coronary embolism of AMI patients after delayed PCI, attenuate vascular endothelial injury, but also could improve TIMI blood flow, and strengthen cardiac systolic function.

All metabolism decreased or disappeared in radiation necrosis, Cho was relative high compared with NAA. Brain abscess: Lac increased in the centre of abscess and perilesion was normal.Conclusion MRS has significant value in detecting and differentiating brain lesions.

Objective To describe the characteristic MR findings in the brain in patients with amyotrophic lateral sclerosis (ALS), and to assess the diagnostic value of conventional MR imaging and fractional anisotropy (FA) of diffusion tensor imaging (DTI). Methods Conventional MR imaging was performed in 14 clinically proved ALS patients and 12 age-matched normal controls. Contrast enhanced MR images were acquired in 2 patients. Axial and coronal DTI scans were performed in 10 patients and 12 normal controls with SE-EPI sequence. The b value was 1 000 s/mm 2, the number of diffusion sensitive gradient direction was 25. For quantitative assessment of the corticospinal tract (CST), FA value of bilateral CST was measured at the level of posterior limb (PL) of the internal capsule (IC) and the cerebral peduncle of the midbrain, respectively, and statistical analysis was performed. Results Focal slight low signal intensity on T 1WI and high signal intensity (hyperintense to gray matter) on T 2WI was demonstrated in 6 ALS cases (42.9%) in bilateral PL of the IC, and the high signal was longitudinally continuous from the PL to the cerebral peduncle on T 2WI coronal plane, corresponding to the course of CST. In another 8 ALS cases (57.1%), the focal slight low signal intensity on T 1WI and slight high signal intensity (isointense to gray matter) on T 2WI was revealed in bilateral PL of the IC. No abnormal contrast enhancement was detected in the 2 cases. In control group, the focal slight low signal intensity on T 1WI and slight high signal intensity (isointense to gray matter) on T 2WI was demonstrated in all 12 subjects in bilateral PL of the IC. FA values of the patient group were significantly lower than that of the control group at the level of the PL of the IC (F=7.38, P

Tangcao pill is commonly applied in adjuvant and even alternative therapy for patients with AIDS. However, the herb contains complex ingredients, but with unknown effect against anti-HIV drug and unknown function. Because CYP450 emzyme is the main metabolic enzymes of the drug, it is of important significance to study the regulation of CYP450 enzymes before and after the combined administration of Tangcao pill and EFV. Proteomics, due to its high throughout and high sensitivity, has been widely applied in CYP450 enzyme study. In this paper, liver microsomes were separated through differential centrifugation. Their proteins were separated through SDS-PAGE. The three protein bands that CYP450 enzymes were located were cut and identified by liquid chromatography tandem mass spectrometry. Totally 16 CYP450 isoenzymes were identified. Furthermore, in order to make a quantitative analysis on the effect of tang herb on CYP450 emzyme, the multiple reaction monitoring (MRM) technology based on MS was adopted. The CYP2C11 was selected based on the results of the mass spectrum identification of proteins. The characteristic polypeptides were obtained through searching Expasy blast database. The m/z of the fragment ions was less than 800. In the paper, the m/z of ion pairs of CYP2C11 were 711.5/232.1, 711.5/319.2, 711.5/466.2 and 711.5/595.3, and the m/z of ESAT-6 (internal standard, IS) were 735.5/215.3, 735.5/389.3, 735.5/460.3 and 735.5/524.3. The relative peak (analyte/IS) area was adopted for the relative quantitative analysis. Compared with the EFV single administration group, the EFV and Tangcao pill combined administration group showed a 1.6-fold increase in CYP2C11. The results of the paper indicated that Tangcao pill may affect drug metabolism by regulating metabolic enzymes such as CYP2C11, but the specific mechanism still unknown.

OBJECTIVETo study the combination of Mandibular distraction and orthognathic techniques for the reconstruction of adult hemifacial microsomia.

METHODSThe three-dimensional CT reconstruction data was used with Mimics for preoperation design. The osteotomy location, distraction vector, distraction distance were decided before operation with a surgical guider. At the first stage, internal distractor was implanted after ostetomy through an extra-oral approach. The distraction begun 5-7 days after operation with a frequency of 1 mm/day. After distraction, the distractor was maintained for 3-6 months. At the second stage, the distractor was removed. Le Fort I osteotomy was performed in order to correct the cross-bite and improve the facial contour. Usually, bone graft was inserted into the gap after Le Fort I osteotomy. The genioplasty was also performed if necessary.

RESULTS9 cases of adult hemifacial microsomia with severe mandibular deviation were treated. The facial asymmetry were improved greatly. 1 patient suffered an wound infection in the maxillary region after Le Fort I osteotomy and healed uneventfully with wound irrigation.

CONCLUSIONSMandibular distraction combined with orthognathic surgery is an effective procedure for adult hemifacial microsomia with complicated mandibular hypoplasia.
