Objective To evaluate the clinical,neuroimaging and electrophysiology features of 62 patients with multiple system atrophy(MSA).Methods Sixty-two cases with diagnosis of probable MSA were recruited in a retrospective studied.Clinical,neuroimage and external anal sphincter electromyography (EAS-EMG)data was retrospectively analyzed.Results In 62 cases(44 male and 18 female),the onset age was between 37 and 76.Among them,29 cases(46.8 % )were MSA-A,with orthostatie hypotension as the main clinical manifestation;24 cases(38.7 % )were MSA-C,with cerebellar ataxia ag the main chnical manifestation;9 cases(14.5 % )were MSA-P,with extrapyramidal symptoms as the main clinical manifestation.MRI showed that main lesion of MSA-A was in the cerebellum:that of MSA-C was in the cerebellum,pons and medulla;and that of MSA-P was in the putamen.Fifty-one cases did EAS-EMG and 46 cases showed neurogenie impairments.Nineteen cases were initially misdiagnosed with other diseases.Conclusions MSA is easy to be omitted or misdiagnosed at early stage.The diagnostie rate of MSA can be increased by the combination of clinical expressions,neuroimage,EAS-EMG and other necessary examinations.

Objective To investigate the clinical, electrophysiological and pathological features of critical illness polyneuropathy and myopathy (CIPNM). Methods The clinical outcomes, electromyogram Results as well as pathological features in nerves and muscles of 3 patients with CIPNM were investigated and analyzed. Results 3 patients were all provided with assisted respiration after tracheal intubation. 7～10 d after intubation, all the patients emerged muscle strength and tendon reflexes of extremities weakening; while 14 days after that, 2 patients appeared amyotrophy of extremities. Electromyogram showed that the conduction of many motor and sensory nerves for extremities decreased, while the amplitude of compound muscle action potential (CMAP) of part of motor nerves decreased. Biopsy for nerves revealed decreased medullated nerve fibers and regeneration phenomenon of auxiliary fibers; while that for muscles showed neuralgic damage and myopathy-like changes. Conclusion CIPNM can complicate after tracheal intubation. The electrophysiological and pathological examinations for nerves and muscles can be helpful for the diagnosis.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

Objective To analyze the clinical,imaging and pathological features of cortical vein thrombosis (CoVT).Methods Three cases of cortical vein thrombosis were diagnosed in our hospital from February 2010 to October 2012.We reviewed and summarized their clinical manifestation,radiological feature and pathological characteristics.Results All patients were young with acute onset.The main clinical manifestations included headache,epilepsy or limbs weakness.Two cases had intracranial hypertension.One case had decreased activity of protein S.One had increased plasma homocysteine.Brain computed tomography scan showed hypodensity lesion with some hyperdensity inside.Cranial routine magnetic resonance imaging showed long signal in T1-weighed image and T2-weighed image,with occasional short T1 signal inside.Contrast-enhanced magnetic resonance imaging revealed heterogeneous enhancement.All of 3 cases underwent brain biopsy because of the suspected diagnosis of brain tumor.Brain pathology showed the local necrosis and hemorrhage,dilated small vein with congestion or thrombosis.Neuronal degeneration,hyperplasia of gliocyte,hyperplasia of endotheliocyte in small blood vessels with reaction of histiocytes was also displayed.Duration from initial visit to final diagnosis was from 14 days to 2 months.Conclusions CoVT has various clinical and radiological manifestations and it is easy to misdiagnose as brain tumor.Careful analysis of clinical and imaging data could improve its diagnostic accuracy.Brain biopsy would also be helpful for diagnosis.

Objective To analyze the clinical,imaging and pathological features of cortical vein thrombosis (CoVT). Methods Ten patients with CoVT (4 patients with CoVT alone and 6 patients with CoVT and venous sinus thrombosis)treated at Navy General Hospital from January 2006 to Jun 2013 were collected retrospectively.Its etiology,imaging,and pathological features of brain tissue in 3 patients were analyzed. Results Of the 10 patients with CoVT,3 were female and 7 were male.Their mean age was 31 ± 15 years old.(1)Brain CT scan and MRI showed hemorrhagic cerebral infarction,and contrast-enhanced MRI showed scattered heterogeneous enhancement within lesions. DSA could find CoVT at different parts.(2)3 patients underwent brain biopsy because they were initially diagnosed as brain tumor. Pathological examination showed glial cell,endothelial proliferation and phagocytic reaction.Scattered spotty bleeding was observed,and significant expansion of small veins,A few of them had blood stasis and thrombosis. Conclusion CoVT is one kind of intracranial venous thrombosis. It is more common occurred in young and middle aged adults,and most of them were venous sinus thrombosis.It is caused by retrograde thrombosis and spread to cortical veins.CoVT is easily to be misdiagnosed as brain tumor.Combination of clinical and imaging findings is needed for accurate diagnosis.

Objective To suppress the proliferation of lens epithelial cells (LECs) is a primary goal in prevention of after cataract. Recent study demonstrated an effective inhibition of elemene(Ele) on tumor cells. Present study was to investigate the effects of Ele on proliferation and cell cycle of human LECs B3 (HLE-B3). Methods Recombinant human basic fibroblast growth factor(rhbFGF) was utilized to induce proliferation of HLE-B3. Proliferative HLE-B3 was incubated with 80 mg/L Ele in CO_2 incubator for 24 hours. Then the inhibitory effects of Ele on proliferation of HLE-B3 was evaluated by methyl thiazolyl tetrazolium(MTT). The effect of Ele on HLE-B3 morphology was observed under the optical microscope. The effect of Ele on HLE-B3 cell cycle was analyzed by flow cytometer(FCM). Results MTT test showed that the optical density (OD) value of rhbFGF group was remarkably higher than that of control group(0. 599 0 ± 0. 053 1 versus 0. 409 1 ± 0. 042 2) (P ＜ 0. 01), and that of Ele group(0. 450 0 ±0. 061 4) was obviously declined in comparison to rhbFGF group(P ＜0. 01) . The inhibitory rate of Ele was 24.90 %. In proliferation group, the number of HLE-B3 was increased with the normal cell structure and abundant cytoplasm under the optical microscope. However, in Ele group, the number of HLE-B3 was evidently decreased with less cytoplasm, undistinguished cell structure, condensed and aggregated nucleuses. The result of flow cytometer showed that the percentage of HLE-B3 in G_1 phase in rhbFGF group was 42. 062% ± 1. 270% and that in control group was 46. 422% ±3. 765% with a significant difference(P ＜ 0. 05). HLE-B3 in G_1 phase in Ele group (60. 665% ±2.069%) was evidently increased in comparison with rhbFGF group (P ＜ 0. 01). HLE-B3 in S phase in rhbFGF group compared with control group was increased (51.647% ±1.123% versus 31.842% ± 2. 798%) (P ＜ 0. 01), but that in S phase in Ele group(30. 222% ±3.429%) was lower than rhbFGF group (P ＜ 0. 01). HLE-B3 in G_2 phase in rhbFGF group was decreased in comparison with control group (6. 288% ± 0. 966% versus 21. 735% ± 3. 806%, P ＜ 0. 01), and that in G_2 phase in Ele group (9. 112% ± 1. 659%) compared with proliferation group was increased (P ＜ 0. 01). Conclusion Ele could alter the cell cycle of HLE-B3 and effectively inhibit the HLE-B3 proliferation induced by rhbFGF. Ele may be a reliable and effective drug for prevention and treatment of after cataract.

Background Our previous study showed that curcumin suppresses the proliferation of human lens epithelial cells (LECs) in vitro and has an influence on the signal transduction of cyclic adenosine monophosphate (cAMP) and cyclic guanosinc monophosphate (cGMP).Actually,the regulation for biological behavior of LECs in vivo is complex.Objective This study was to investigate the changes of signal transduction of protein kinase (PK) in inhibition of curcumin on human LECs proliferation.Methods HLE-B3 was cultured and then divided into the blank control group,recombinant human basic fibroblast growth factor (rhbFGF) group and rhbFGF+ curcumin group.rhbFGF of 10 ng/ml was added in the medium in the rhbFGF group,and 20 mg/L curcumin was added into rhbFGF-induced cell medium for 24 hours in the rhbFGF+ curcumin group.The expression rates of PKA,PKC,PKG and calmodulin (CaM) in the cells were assayed using flow cytometry.Results The expression rates of PKA protein were (46.847± 1.673) ％,(33.250 ± 2.242) ％ and (71.645 ±2.432) ％ in the blank control group,rhbFGF group and the rhbFGF+ curcumin group,respectively,and the expression rate of PKA protein was significantly reduced in the rhbFGF group compared with the blank control group (t =11.904,P＜0.01),but the expression rate of PKA protein in the rhbFGF+ curcumin group was significnatly higher than that in the rhbFGF group (t=28.430,P＜0.01).In the blank control group,rhbFGF group and the rhbFGF+ curcumin group,the expression rates of PKC protein in the cells were (35.575± 1.937) ％,(50.652±2.068) ％ and (27.662t4.481) ％,those of PKG protein were (63.838±0.486) ％,(86.562 ± 1.325) ％ and (40.733 ± 2.175) ％,while those of CaM protein were (67.408± 1.391)％,(83.887±3.499)％ and (53.785 ± 1.942)％,the expression rates of PKC,PKG and CaM were significantly lower in the rhbFGF group in comparison with the blank control group (all at P＜0.01),and those in the rhbFGF+ curcumin group were significantly declined in comparison with the rhbFGF group (all at P＜0.01).Conclusions Suppression of curcumin on HLE-B3 proliferation probably is associated with the up-regulation of PKA expression and down-regulation of PKC,PKG and CaM expression in the cells.
