Objective To report a case presented with atypical clinical and radiological appearance in the early stage and finally pathologically confirmed as chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids ( CLIPPERS) , aiming to improve the understanding of the disorder. Methods The clinical, imaging, laboratory and pathological features as well as treatment and prognosis of a pathologically confirmed CLIPPERS patient with repeated relapsing-remitting course and stepwise progression in nine years were retrospectively analyzed. Results There were five relapsing-remitting processes in total clinical course of nine years. The clinical and radiological appearance was atypical in the early stage. At the first attack, the patient presented with fever, headache, altered consciousness and epileptic seizure. In the following courses, the patient presented with ataxia, blurred vision and limb weakness. Brain MRI (2006-2009) showed multiple abnormal signals including supratentorial white matter, pons and cerebellum with patchy gadolinium enhancement. Treatment with steroids resulted in a favorable clinical and radiological improvement. The symptoms of this attack included limb weakness, blurred vision, dysdipsia and dysarthria. Physical examination showed cognitive dysfunction, multiple cranial nerves injuries and bilateral pyramidal signs. Brain MRI showed multiple abnormal signals involved pons and cerebellum predominantly as well as supratentorial white matter with punctate gadolinium enhancement peppering the pons and cerebellum. A characteristic predominantly T lymphocytic perivascular infiltration was seen on brain biopsy. Both the imaging and histological findings were consistent with the CLIPPERS features. High-dose steroids treatment was given and obvious clinical and radiological improvements were observed. After discharge, steroids were reduced slowly combined with the use of immunosuppressant to avoid relapse of the disorder. Conclusions There is heterogeneity in clinical manifestations of CLIPPERS with repeated relapsing-remitting course and imaging presentations are sometimes atypical in the early stage, which leads to the misdiagonsis and missed diagnosis. Distinctive pathology is the “gold standard” for definite diagnosis. The nosological position of CLIPPERS is still unclear. Repeated relapse-remitting leads to secondary cerebral atrophy and degeneration, with the risk of progressing to primary central nervous system lymphoma. Early and vigorous steroids treatment with continuing maintenance immunotherapy results in the decreased relapse and best long-term prognosis. The neurologist should strengthen the understanding of CLIPPERS for early correct diagnosis and treatment aiming to reduce the functional disability.

Objective To investigate the expression and clinical significance of MUC1,MUC2,MUC4 and MUC5AC in pancreatic ductal adenocarcinoma(PDA).Methods To analyze the expression profiles of MUC1,MUC2,MUC4 and MUC5AC in PDA(n=26),chronic pancreatitis(CP,n=4),normal pancreas(n=16)and intraductal papillary-mucinous neoplasm(IPMN)(n=2),solid-pseudo-papillary tumor of pancreas(SPT)(n=4),serous cystic neoplasm(SCN)(n=1)using immunohistochemistry.Results Positive staining with MUC1 Was exclusively found in normal pancreas and CP tissues(100%);the expression of MUC1,MUC4 and MUCSAC in PDA was 100%,88.5%(23/26)and 76.9%(20/26)in PDA tissue;MUC2 and MUC5AC were expressed in 2 samples of IPMN;none of the four mucins were expressed in Sfrr and SCN.There was no association between the expression of MUC4,MUC5AC and the clinicopathologic parameters in PDA(P＞0.05).Conclusions Multiple mucins were expressed in PDA.Measurement of the mucin profile including all 4 mueins(MUC1,MUC2,MUC4,and MUC5AC)may be helpful in the diagnosis and differential diagnosis of PDA.

Objective To investigate the effects ofShipi-Gushen-Huayu Recipe on the expressions of collagen I, laminin(LN), transforming growth factor-β1(TGF-β1)andα-smooth muscle actin(α-SMA)in adriamycin-induced renal fibrosis in rats.Methods A total of male SD rats were randomly divided into four groups, with 10 rats in each group: a normal group, a model group, a treatment group and a fosinopril sodium group. Except the rats in the normal group, the rest rats were subjected to renal fibrosisvia tail intravenous injection of adriamycin(4 mg/kg). Two weeks after modeling, the rats in the rreatment group and in the fosinopril sodium group were intragastrically administrated daily withShipi-Gushen-Huayu Recipe extract(43 g/kg)and fosinopril solution(2 mg/kg), respectively,both in the normal group and model group with saline. After 30 days, 24-hours urine protein were determined, and the expressions of collagen I, LN, TGF-β1 andα-SMA in kidney tissue were detected with immunohistochemistry staining.Results The expressions of collagen I(24.64±0.67vs. 32.86±0.88), LN(18.71±0.72vs. 28.35±0.87), TGF-β1(14.71±0.68vs. 18.35±0.96)andα-SMA(17.64±0.74vs. 25.86±0.85)in the treatment group were significantly lower than those in the model group(allP<0.01). The expressions of collagen I, LN, TGF-β1 andα-SMA in the fosinopril sodium group were 27.33±0.73, 20.44±0.81, 15.44±0.85 and 19.33±0.77, respectively. There was no statistically significant difference between the expressions of collagen I, LN, TGF-β1 andα-SMA in the treatment group and in the fosinopril sodium group.ConclusionShipi-Gushen-Huayu Recipe can significantly down regulate the expressions of collagen I, LN, TGF-β1 andα-SMA in adriamycin-induced renal fibrosis in rats.

Objective To observe the therapeutic effect of Shenmai injection on rats with acute edematous pancreatitis (AEP) and its mechanism.Methods The model of AEP in rats was induced by intraperitoneal injection of caerulein every one hour for 7 times.One hour after last injection,intravenous Shenmai injection (5 ml · kg-1 · d-1) was given to rats in Shenmai injection treatment (SI) group,while same amount of normal saline was given to rats in control (AEP) group.One hour and 1,3,5,7 d after AEP induction,the blood was taken,and the method of double antibody sandwich enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of amylase,platelet activating factor (PAF),vascular endothelial growth factor (VEGF).The rats were sacrificed at 7 and 14 d,and pancreatic tissue samples were harvested.RT-PCR and Western Blot were used to determine the expression of NF-κB mRNA and protein,and normal pancreatic tissue samples were used as control.The positive expression of CD31 in pancreatic tissue was determined by immunohistochemical method to calculate microvascular density (MVD).Results The serum levels of amylase and PAF in both groups were increased and gradually decreased 3 days later,while the decrement in SI group was greater than that of AEP group.At the 5th day after AEP induction,the serum levels of amylase in SI group and AEP group were (4569 ± 158),(5056 ± 198) U/L,and the serum levels of PAF were (25.30 ± 4.76),(36.06 ± 5.57)μg/L,and the difference between the two groups was statistically significant (P ＜ 0.05).The serum levels of VEGF were increased 1 d after AEP induction,and the increase in SI group was greater than that of AEP group 3 d later,and the serum levels of VEGF were (139.78 ±24.30),(118.51 ±21.70)pg/ml at 5th day,and the difference between the two groups was statistically significant (P ＜ 0.05).The expression levels of NF-κB mRNA and protein of pancreatic tissue in SI group were O.834 ±0.031 and 0.49±0.24,and MVD was 6.41 ± 1.14,while the corresponding values in AEP group were 1.000 ± 0.059,0.93 ± 0.45,3.62 ± 0.89,and the difference between the two groups was statistically significant (P ＜ 0.05 or P ＜ 0.01).Conclusions In the course of acute pancreatitis,Shenmai injection has the therapeutic effects of promoting new angiogenesis,improving the microcirculation,reducing the inflammatory cascade.

Neurosurgical emergencies including intracranial hemorrhage and head trauma have high mortality and morbidity rates and meanwhile are often accompanied with coagulation disorders. On one hand, coagulation disorder follows traumatic brain injury;on the other hand, the increasing use of anticoagulant and antiplatelet treatment for cardiovascular diseases increases the risk of death among patients with brain trauma or bleeding. Once the intracranial pressure increases, such patients need emergency surgical intervention, but coagulation disorder is a relative contraindication. This article reviews the pathogenesis and treatment of coagulation disorders in patients with neurosurgical emergency. It also analyzes clinical monitoring indices for such patients and their variations and summarizes the strategies and measures of perioperative management.

Objective To explore the feasibility of 256-slice whole-brain CT perfusion (CTP) in evaluate graft reperfusion after surgical revascularization and hemodynamic alterations before and after surgery in Moyamoya disease. Methods Twenty-five cases with Moyamoya disease were scanned on a 256-slice CT.CTP was performed pre- and post- surgical revascularization. The wolumetric CT angiographic ( CTA ) images were generated from volumetric data acquired at the arterial phase of CTP. CBF, CBV, TTP and MTT were measured in functional maps at the operated side within middle cerebral artery perfusion areas and contralateral mirroring areas. Relative CBF( rCBF), relative CBV (rCBV), relative TTP (rTTP), relative MTT (rMTT) were also obtained. Differences in perfusion CT values pre- and post operation were assessed with the paired t test or matched-pairs signed-ranks test. Data with normal distribution was present as : (x-)± s,while those with the non-normal distribution were present as M ( P25-P75 ). Results All the direct graft patencies were displayed on volumetric CTA. No significant differences were found between volumetric CTA and conventional CTA. Postoperative CBF, rCBF and rCBV values of the operated side [ 72. 86 (55.54-112. 19) ml · 100 g-1 · min-1 , 1. 31 ( 1.05-1.73), 1.45 ±0. 62] were significantly higher than those before operation [46.72(28.57-57.67) ml · 100 g-1 · min-1, 0.53(0.33-0.82), 1.01 ±0.36](Z=- 2.72, - 2. 98, t = - 2. 85, P ＜ 0. 05 ). Postoperative MTT, TTP and rTTP values of the operated side [ (3.98 ± 2. 36 ) s, ( 17.56 ± 4. 38 ) s, 1.01 ± 0. 09 ] were significantly lower than those before operation [(5.43±2.07) s,(19.40±3.87) s,1.14±0.28] (t=2.41,2.17,2.17, respectively, P＜0.05).However, no significant differences were detected for changes of CBV and rMTT after revascularization ( P ＞0. 05). Conclusion 256-slice CT has the potential value for the non-invasive assessment of both the graft patency and cerebral hemodynamics changes in moyamoya disease after surgery with administration of one contrast medium bolus in a single examination.

Objective Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently described brainstem-predominant inflammatory disorder responsive to steroids with characteristic magnetic resonance imaging(MRI) feature.There was no case report in China.The aim of this study was to characterize the clinical and imaging patterns of CLIPPERS for early diagnosis and treatment.Method Clinical and imaging data and therapeutic methods and following up after treatment of 1 patient diagnosed CLIPPERS were reviewed retrospectively.Results The patient presented with subacute weakness of the lower extremities,gait ataxia and facial numbness.Cerebellar ataxia and pyramidal signs were the main positive signs on neurological examinations.Brain MRI showed punctate gadolinium enhancement peppering the pons and cerebellar.Treatment with steroids led to rapid clinical improvement and marked resolution of MRI lesions which accorded with characteristics of CLIPPERS.Conclusions There are no characteristic clinical manifestations of CLIPPERS.Punctate gadolinium enhancement peppering the pons is the distinct magnetic resonance imaging feature which may suggest the clinical diagnosis of CLIPPERS.Early treatment with steroids can improve the prognosis.
