Objective To explore the mechanisms and the location of the lesion which result in ataxia in patients with Miller Fisher syndrome (short for Fisher syndrome). Methods The clinical features were analyzed and auxiliary examinations were performed in 9 patients with Miller Fisher syndrome, while the pertinent literature was reviewed to analyze the possible mechanism responsible for ataxia in Fisher syndrome. Results All the nine patients manifested the specific clinical features of Fisher syndrome, including external ophthalmoplegia, ataxia, and attenuated or obsolescent tendon reflexes in all the limbs. 8 patients complained diplopia. The symptoms of internal ophthalmoplegia, mydriasis and loss of pupillary light reflex were found in 8 patients. Peripheral facial paralysis was found in 5 cases, glossopharyngeal nerve and vagus nerve paralysis were found in 1 patient. Cerebrospinal fluid (CSF) examinations were performed in 7 patients and showed increase in protein contemt in 6 patients, but CSF specimens in all patients were devoid of leucoytc. Electromyogram (EMG) indicated the existence of myogenic damages in 5 patients. Electroencephalogram was performed in 5 patients and no abnormity was found. Magnetic resonance imaging (MRI) or computerized tomography (CT) scanning of the brain did not reveal any significant abnormities in the cerebellum in all the patients. All the nine patients, who received dexamethasone and some other routine neuroprotective therapies, had a good prognosis. Conclusions On the basis of present study, no definite evidences to support that cerebellar lesion may cause ataxia in the patients with Fisher syndrome. It is assumed that external ophthalmoplegia may play a role in causing ataxia. Further studies are needed to ascertain the exact mechanisms responsible for ataxia in Fisher syndrome.

At present, about one third organ transplantation recipients were hepatocellular carcinoma (HCC) patients even in the most advanced transplant center in the world. HCC especially the early primary HCC has been listed as one of the indications of liver transplantation(LT) in the most organ transplant center in the world. However, due to the tumor recurrence and metastasis following LT, many patients would be dead following transplantation in about 2 years later. Their five-year survival rate was only 50 percent in benign final phase liver disease patients. The current researches for this phenomenon were still shallow both in mechanisms and treatments. How to prevent tumor recurrence has become serious challenges and must be faced in liver transplantation surgery. Obviously, to discover the molecular mechanisms and predisposing factors of following LT recurrence, to explore appropriate standards for LT in HCC patients and to strengthen perioperative management are the only way for increasing LT efficacy.

Objective To investigate the clinical importance and the relationship between the levels of plasma total homocysteine (Hcy), serum folic acid and vitamin B 12 , and the occurrence and development of ischemic leukoaraeosis (LA). Methods Ischemic LA group and normal control group with 100 cases for each were studied. The 100 cases in ischemic LA group were firmly diagnosed by CT or / and MRI. The levels of plasma total Hcy, serum folic acid and vitamin B 12 of the patients in ischemic LA group were measured, and compared with that in control group. Results The level of plasma Hcy in ischemic LA group (19.79?5.25?mol/L) was significantly higher than that in control group (12.02?2.11?mol/L), while the levels of serum folic acid and vitamin B 12 in ischemic LA group (2.08?0.84ng/ml and 140.13?45.49pg/ml) were lower than that in control group (4.39?1.30ng/ml, 297.45?120.23pg/ml). The differences between two groups were statistically significant (P

BACKGROUND: Troponin I (Tn I ) could inhibit the growth of vascular endothelial cells, inhibit neovascularization,through which to inhibit the development and metastasis of solid tumor. Similar to Tn I, TnC also exists in non-muscular tissue, but does it has the analogous activity of anticancer like Tn I ?OBJECTIVE: To explore the effect of recombinant human TnC (rhTnC) on the growth of human umbilical vein endothelial cells (HUV-EC) and mouse xenograft tumor.DESIGN: Controlled observation in vivo and in vitro.SETTING: Research Institute of Medicine, Chongqing K.E.W Pharmaceutical Co., Ltd. and Department of Biochemistry of Chongqing Medical University.MATERIALS: The experiment was conducted in the Biochemical Laboratory of Research Institute of Medicine,Chongqing K.E.W Pharmaceutical Co., Ltd. from March 2003 to December 2004. 100 Kunming mice either male or female of 15-22 g purchased from Chongqing Academy of Chinese Materia Medica. E.coli BL21 (DE3)pLysS/pET3b-TnC provided by Chongqing K.E.W Pharmaceutical Co., Ltd. HUV-EC (Shanghai Institute of Biochemistry and Cell Biology, Chinese Academy of Sciences).METHODS: Human TnC cDNA was obtained from human thymus cDNA library using PCR. The colony was cloned in E.coli and a bacterial strain of gene engineering E.coli BL21 (DE3) pLysS/pET3b-TnC was obtained, which could express hTnC. The recombinant human TnC (rhTnC) was purified with affinity chromatography of Ni-NTA agarose. ①In vitro cell experiment: HUV-ECs were seeded in the 96-well plates at density of 2×103 cells per well and co-cultured with rhTnC of 1, 5, 10, and 50 mg/L for 3 days. The absorption (A value) was detected with microplate reader at 540 nm and the inhibition rate of cell growth was calculated. Meanwhile, the 50% inhibiting dose (IC50 value) was assayed by LOGIT method. ②In vivo animal experiment: Ascites tumor (S-180) that had been inoculated for 7-8 days was harvested. The tumor cells were diluted to 1 ×1010 L-1 and 0.2 rnL was subaxillarily and intraperitoneally injected into each mouse (50 mice in each group). The next day, the mice were randomly divided into 5 groups: rhTnC 20 mg/kg group, rhTnC 10 mg/kg group, rhTnC 5 mg/kg group, Cyclophosphamide (Cy) group and control group with 10 mice in each group. The rhTnC 20,10 and 5 mg/kg groups were given administration at the corresponding doses, once a day for 7 days; 50 mg/kg Cy was given the Cy group one after an interval of day, and the same volume normal saline was given to the control group. One day after the last time of administration, all mice were killed and the tumor was harvested and weighed. The inhibition rate of tumor growth was calculated: tumor inhibition rate=[(Average weight of tumor in control group-Average weight of tumor in drug group)/Average weight of control group]×100%.MAIN OUTCOME MEASURES: Inhibition rate of rhTnC to HUV-EC proliferation in cell experiment in vitro and mouse xenograft tumor in animal experiment in vivo.RESULTS: ①In vitro cell culture showed that rhTnC suppressed HUV-EC proliferation in a dose-dependent manner (IC50=7.5 mg/L). ②Similar to the result of in vitro cell experiment, after intraperitoneal administration, the inhibition rate of rhTnC 5, 10, and 20 mg/kg groups was higher than that of control group (P ＜ 0.01); after subaxillary administration, the inhibition rate of rhTnC 5, 10, and 20 mg/kg groups was also higher than that of control group (P ＜ 0.05-0.01). There was no significant difference in the inhibition rate between two administration approaches (P ＞ 0.05).CONCLUSION: rhTnC is capable of inhibiting the proliferation of HUV-EC dose-dependently, and displays the activities of inhibiting the proliferation of HUV-EC and anti-tumor.

Aiming at the problem of scaffold degradation in bone tissue engineering, we studied the feasibility that controlls bone defect repair effect with the inhomogeneous structure of scaffold. The prediction model of bone defect repair which contains governing equations for bone formation and scaffold degradation was constructed on the basis of analyzing the process and main influence factors of bone repair in bone tissue engineering. The process of bone defect repair and bone structure after repairing can be predicted by combining the model with finite element method (FEM). Bone defect repair effects with homogenous and inhomogeneous scaffold were simulated respectively by using the above method. The simulation results illustrated that repair effect could be impacted by scaffold structure obviously and it can also be controlled via the inhomogeneous structure of scaffold with some feasibility.
