Objective TO explore the etiology and pathogenesis of multiple sclerosis. Methods The information of pa-tients from 413 MS was analyzed comprehensively by the clinical statistical methods. Results Common cold was the com-monest factor causing MS, and fever,fatigue and childbirth were also the common causes. Immunological disturbance exis-ted in MS. CD~+_4 cell decreased in most of MS patients, but the distribution of CD~+_8 cell was not regular. The level of sexhormones was abnormal in MS,but it was not the same in male and female. There were three patients having family histo-ry of MS. Conclusion Virus infection,sex hormones and heredity factors are all related to MS through facilitating immu-nological disturbance.

Objective: To analyze the clinical value of modified endoscopic nipple resection in duodenal papillary adenoma resection Methods: 40 patients with duodenal papillary adenoma were randomly divided into observation group (20 cases) and control group (20 cases)according to the random number table. The patients of control group were treated by conventional resection of papillary adenoma, while the patients of observation group were treated by modified endoscopic nipple resection. The resection rate and the implantation of stent between the two groups were compared. Besides, the occurrence rate of complication and postoperative follow-up between the two groups also were compared. Results: The complete resection rate of observation group (95.00%) was not significant difference with that of control group (90.00%), while en bloc resection rate of observation group (85.00%) significant higher than that of control group (55.00%) (x2=4.28, P<0.05).There was not statistically significant difference between the two groups about the implantation of stent (x2=0.36, P>0.05). In postoperative three months, the difference of recently complication between the two groups was significant (x2=6.14, P<0.05). While the difference of long-term complication between the two groups was no significant (x2=0.36, P>0.05) in more than postoperative three months. After the follow-up of one year, the recurrence rate of observation group (10.34%) was no significant with that of control group (14.29%)(x2=0.17, P>0.05). Conclusion: The modified endoscopic nipple resection can enhance the en bloc resection rate, and reduce the incidence of complications and the recurrence rate. Besides, it has many dominances including higher feasibility in clinical practices. Therefore, its promotion is worthy.

Objective To summarize the features of multiple sclerosis (MS) in China. Methods The clinical manifestations and inducements of 413 MS patients are comprehensively analyzed using clinical statistical method. Other parameters are also analyzed by electromyography and brainstem auditory evoked potential. Results MS in China mainly invades young and middle-aged people, with a higher ratio in female than in male. MS was found mostly acute or subacute in onset and usually due to an inducement mainly consisting of common cold, fever, cyesis and fatigue. The first seen symptoms were various and complicated, but mainly showed different types of visual disturbance such as the acuity of vision decrease, constriction of visual field and diplopia. Limb paralysis, sensory abnormality and visual disturbance were found the commonest symptoms. Lhermitte’s sign was common. Paroxysmal symptoms as algospasm and seizure were relatively common. Electromyography and brainstem evoked potential showed that peripheral nervous system damage might occur in MS. Spinal cord and visual nerve were found the mostly invaded according to the clinical data. Conclusion The features of MS in China should be different from those in the western countries.

The CT findings in 200 cases of increased intracranial pressure without localizing signs were reported 132 out of the 200 cases (63.1%) were CT positive, among them there were 8 cases with brain metastatic cancer, 11 cerebral cysticercosis, 14 intracranial inflammatory lesions, 18 hydrocephalus with symmetrical ventricular enlargement, 66 mass lesions in the brain and 15 others. 77 out of the 209 cases (36.9%) were CT negative, among whom the diagnosis of the 61 cases coincided with that of BIH. It seems that our BIH cases were much different from those typical cases reported abroad, and the cause would be pending further investigation. It is to be noted that the following remarks, according to our study, would be associated with the positive findings in CT examination: 1. age, 60 years; 2. course of disease, within 6 months; 3. papilloedema and/or "soft" signs; and 4. local and severe abnomalities in EEG.

BACKGROUND: Precartilaginous stem cells (PSCs) have strong proliferation ability and differentiation potential,but they are instable and prone to differentiate.Importing exogenous gene could immortalize them and leave phenotype character unchanged.OBJECTIVE: To establish immortalized precartilaginous stem cells (PSCs) from neonatal SD rats in vitro for the further related research about the differentiation mechanism and clinical application of precartilaginous stem cells.DESIGN,TIME AND SETTING: Single sample observation.The study was carried out in the Department of Orthopedics.Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from October 2005 to September 2006.MATERIALS: Neonatal SD rats,irrespective of gender,24-hour old,were used for prepare PSCs.METHODS: By using LipofectamineTM 2000,a gene transfection reagent,plasmid pCMVSV40T/PUR containing the simian virus 40 large T antigene gene (SV40Tag) was transfected into the primary cultured PSCs isolated by immuniomagnetic beads coasted with the second antibody.Colonies were isolated by puromycin selection and expanded by many passages.MAIN OUTCOME MEASURES: Biological character of PSCs; plasmid identification; biological character of transfected cells and identification; RT-PCR; growth curve.RESULTS: Immunomagnetic beads separation system obtains PSCs,which was confirmed as fibroblast growth factor receptor-3 (FGFR-3) positive PSCs.Double restriction enzyme was cut,electrophoresis confirmed pCMV was 3 kb,SV40T was 2.3 kb.A particular anti-puromycin cell clone was acquired,which was confirmed as FGFR-3 positive PSCs.The total RNA was isolated from the positive cell clones,and a 588 bp fragment,which was specific for the SV40T antigene gene,was amplified.The transfected cells were expanded to immortalized cell strain,named as immortalized precartilaginous stem cells (IPSCs).Thepopulation doubling time of IPSCs was (22.98±2.77) hours,no significant effect of subculture,freezing and recovering had been found.CONCLUSION: Precartilaginous stem cells could be isolated from neonatal SD rats,cultured in vitro,and immortalized through the transfection of pCMVSV40T/PUR.

Objective To investigate brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) concentrations in serum and cerebrospinal fluid (CSF) in patients with multiple sclerosis (MS) and neuromyelitis optica (NMO),and their neuroprotective effects.Methods Sixty-two patients (49 patients were MS and 13 patients were NMO) and 21 controls were investigated in our studies.The disability severity in MS and NMO patients in their relapse period was assessed by the Expanded Disability Status Scale (EDSS).MRI scanning of brain,spinal cord or optic nerve was examined and the oligoclonal band in serum and CSF were detected.BDNF and GDNF concentrations in serum and CSF were assessed by Liquid Assay.Results There were no significant differences of BDNF (μg/L,5.616±0.650 in serum and 0.186±0.012 in CSF of MS patients;6.584±0.929 in serum and 0.176± 0.006 in CSF of NMO patients) and GDNF (μg/L,0.039 in serum and 0.080 in CSF of MS patients;0.029 in serum and 0.050 in CSF of NMO patients) concentrations in serum and CSF in patients with MS and NMO in relapse,compared with those in controls.There was a positive correlation between BDNF and GDNF concentrations in CSF (r=0.756,P=0.000),and a negative correlation between BDNF and GDNF concentrations in serum (r=-0.329,P=0.018).There were no correlations of BDNF and GDNF concentrations in serum and CSF with EDSS,blood brain barrier index,Delpech index and Tourtellotte synthesis rate.There were no significant differences of BDNF and GDNF concentration in serum and CSF between NMO/MS patients with and without atrophy.Conclusions The level of BDNF in patients with MS and NMO is correlated with that of GDNF,which may have a synergistic neurotrophic effect on MS and NMO.BDNF and GDNF are not associated with the blood-brain harrier destruction and lgG synthesis in central nervous system.However,associations of BDNF and GDNF with functional disability and neuron atrophy in NMO and MS patients still need further studies.
