Objective To investigate the clinical and imaging characteristics of posterior reversible encephalopathy syndrome (PRES).Methods The clinical and imaging data of 7 patients with PRES were analyzed retrospectively.Results Among the 7 cases with PRES, 3 cases were secondary to pregnancy induced hypertension syndrome, 3 cases secondary to renal failure, 1 case secondary to hypertension.The clinical characteristics were that 7 cases presented with headache and disturbance of vision, 6 with epilepsy, 4 with nausea and vomitting, 1 with hemiparesis, 1 with ataxia.Cranial CT examination in 6 cases revealed occipital low density lesions in 3, widely white matter edema in 2, multiple small hematomas in 1, and no lesion in 2. Brain MRI showed that the occipital lobe was involved in 7 cases, cerebellar in 3, brain stem in 2, fronto-parietal subcortical white matter in 2, caudate nucleus in 1, thalamus in 1. The lesion showed gyrus-like abnominal signals in lobes and patchy abnormal signals in the other areas. The lesion showed low or iso-signal in T1WI, high signal in T2WI and Flair. 2 cases enhancement scannings showed no enhancement effect in 1 and gyrus, patchy and ring-like enhancement in another. The lesions demonstrated mild high signals in 2, low signal in 1 and no abnormalmality in 1 on DWI among 4 cases.Conclusions The headache, disturbance of vision and epilepsy are the principal clinical symptom in PRES . The imaging features of PRES are symmetrical long T1 and T2 signals on the bilateral posterior white matters of cerebrum.

AIM: To investigate the angiogenesis in the process of sarcoma 180 (S_(180)) tumor transplantation and changes of regulator factors, and explore the possible mechanism. METHODS: The S_(180) transplanted tumor in the Km mouse was used to detect the tumor angiogenesis by immunohistochemical examination of FⅧ. The levels of VEGF (V) and endostatin (E) in serum and the homogenate of tumor tissue were measured by ELISA and EIA, and the correlation between tumor weight and microvessel count (MVC) and morphology in tumor was also analyzed by multiple ANNOVA method. RESULTS: MVC, the relative count of total vessels and relative total vessel area increased with the development of transplanted S_ 180 . VEGF level in tumor tissue were higher at the 10th and 15th day than the 5th day after tumor transplantation. Endostatin in the tumor tissue and serum both reached the highest level at the 15th day, V/E ratio did not changed in this process. Furthermore, MVC, average vessel area and relative total area had a significant correlation with tumor weight. CONCLUSION: MVC increases in the development of S_(180) transplantation tumor and is related with the tumor weight; the positive regulator of angiogenesis in the tumor tissue is up-regulated during tumor growth, and the regulators in the tumor tissue maintains a relative balance.

Objective To investigate the influence of coix seed triglyceride combined with transcatheter arterial chemoembolization (TACE) therapy on AFP, CD4﹢CD25﹢regulatory T (Treg) cells and cellular immune function in patients with advanced primary hepatocellular carcinoma (HCC). Methods A total of 50 patients with inoperable HCC, whose imaging examination showed no distant metastasis, were divided into the study group (n=25) and the control group (n=25). Coix seed triglyceride together with TACE was employed for the patients of the study group, while only TACE was adopted for the patients of the control group. For the patients of the study group, transcatheter hepatic artery infusion of 100 ml coix seed triglyceride was carried out during the performance of TACE, and postoperative intravenous drip of coix seed triglyceride (200 ml/d) was used for 5 days. The peripheral blood samples were collected one week before and one month after the treatment to detect the changes of AFP and T lymphocyte subsets (CD3﹢, CD4﹢, CD8﹢,CD4﹢/CD8﹢ and Treg) levels. One month after the treatment, enhanced CT, MRI or PET-CT was performed to evaluate the necrosis degree of the tumor. Results After the treatment, AFP levels was decreased in both groups, when compared the preoperative data the differences were statistically significant (P<0.01); the tumor necrosis rate of the study group was (57.7 ±8.2)%, which was slightly higher than (57.7±8.2)% of the control group, however, the difference was not statistically significant (P>0.05). In the study group, the percentage of Treg cells decreased from preoperative (8.27±6.65)%to postoperative (4.22± 1.59)%, the difference was statistically significant (P<0.01). The percentages of CD3﹢ and CD4﹢ and the ratio of CD4﹢/CD8﹢ increased from preoperative (55.78 ±13.66)%, (43.98 ±14.00)% and 1.22 ±0.64 to postoperative (62.29±10.78)%(P<0.01),(51.82±16.32)% (P<0.05) and 1.54±0.80 (P<0.05) respectively, while the percentage of CD8﹢decreased from preoperative (45.71±12.94)%to postoperative (39.70±12.41)%(P<0.05). In the control group, no statistically significant differences in the above mentioned indexes existed between preoperative data and postoperative ones (P>0.05). Conclusion In treating advanced primary HCC, coix seed triglyceride combined with TACE can reduce the percentage of Treg cells, thus, influence the patient’s cellular immune status and possibly decrease the recurrence rate of HCC after TACE therapy.
