Objective To investigate the effect of early rehabilitation treatment in the patients with small cerebral hemorrhage and its possible mechanisms .Methods 133 patients with cerebral hemorrhage were randomly divided into the routine treatment , non-early rehabilitation and early rehabilitation groups and given the routine drug treatment .The early rehabilitation group and the non-early rehabilitation group were additionally given the rehabilitative training after 2 d and 14 d respectively .The scores of Fugl-Meyer reassessment and the Barthel index were assessed before training and after 4-week training ,and the serum levels of circulat-ing endotheial progenitor cells(EPCs) and vascular endotheial cell growth factors(VEGF) were detected .Results Compared with the routine treatment group and the non-early rehabilitation group ,the scores of Fugl-Meyer reassessment and the Barthel index af-ter treatment in the early rehabilitation group were significantly increased (P< 0 .01) .The serum levels of circulating EPCs and VEGF in the early rehabilitation group were also significantly increased compared with the routine treatment group control (P<0 .01) .Conclusion Early rehabilitation treatment can obviously improve the limb movement function and the daily living ability in the patients with small cerebral hemorrhage ,its mechanisms may be involved with the increase of circulating EPCs and VEGF .

Objective:To evaluate the cytotoxicity of sodium hypochlorite(NaOCl) and chloramine-T at a same available chlorine concentration. Methods: L929 fibroblasts were used to test the cytotoxicity of NaOCl and chloramine-T at a same available chlorine concentration (0.500 0%, 0.250 0%,0.200 0%, 0.150 0%, 0.125 0%, 0.062 5%). Cell viability after 2 h, 30 min or 10 min exposure were measured by MTT assay. Results: Except the 0.500 0%-2 h group and 0.062 5%-30 min group, cell viability of NaOCl groups were higher than chloramine-T group(P<0.05). Conclusion: NaOCl solution has less cytotoxicity than chloramine-T at a same available chlorine concentration lower than 0.250 0%.

Objective To find out the distribution and changing trend of pathogens in positive blood cultures. Methods To analyze 183 isolates from 2010 blood specimens then the results were compared with the relative clinical data. Results A total of 183 strains were isolated from all blood specimens, of which 139 strains (76.0%) were identified as pathogens, where 69 strains (49.6%)being Gram-positive cocci, 57 strains (41.0%) gram-negative bacilli, and 13 strains (9.4%) fungi, respectively. The other 44 strains (24.0%) were contaminated. The major pathogens in 139 strains were Coagulase-negative staphylococci (40 strains, 28.8%), Pseudomonas aeruginosa (17 strains, 12.2%), Escherichia coli (15 strains, 10.8%), fungi 13 strains (9.4%) and Staphylococcus aureus (9 strains, 6.5%). Conclusion The dominant pathogens in positive blood cultures were gram-positive cocci, while gram-negative bacilli cultures were becoming less.

Objective To estimative the relationship between ras gene mutation,PCNA overexpression and the recurrence and prognosis of gallbladder cancer.Methods PCNA was studied by ABC immunohistology, ras gene mutation by PCR-RELP analysis.Results Histology,Nevin staging and operative methods were relevant to the prognosis of gallbladder cancer.The patient with stag IV,V gallbladder cancer had a poor prognosis;radical operations could prolong patients survival time.The mortal risk of patients with ras gene mutation was 1.62 times higher than that without ras gene mutation,with high overexpression of PCNA was 2.2 times higher than that with low expression of PCNA. Conclusions Differentiation degree, Nevin′s staging, mutation of ras gene and overexpresion of PCNA could be the prognostic factors in gallbladder cancer,and could help to select the operative procedure and to eluvate the surrival.

Objective To make clear the relationship between adenoma,malignant transformation of ade- noma and carcinoma in gallbladder.Methodes The nuclear morphometry was performed with a TJTY-300 Auto- matic Image Analyser and PCNA was measured with immunohistochemisty in 25 cases of carcinoma,20 cases of adenoma and 3 cases of normal gallbladder.Results (1) Cell DNA content,atypia and PCNA index were in- creased gradually from the normal cell to dysplasia to malignant transformation of adenoma to carcinoma in gallblad- der;(2) Aneuploidy in gallbladder adenoma and PCNA index had significant relationship to the size of adenoma and gallstones (P

Objectives To analyse the clinical feature,drug and surgical treatment and prognosis of rheumatic diseases associat- ed corneal melting.Design Retrospective case series.Participants 14 patients (22 eyes) with rheumatic diseases associated corneal melting.Methods The clinical data of patients were analysed,including history,visual acuity,slit-lamp microscopy examination,drug and surgical treatment and follow-up results.Main Outcome Measures The clinical feature,therapeutic effects and recurrence. Results The follow-up was 6～24 months.Rheumatic diseases associated corneal melting always firstly occurred from the upper corneal limbus.The marginal lesions of cornea included melting of the stroma,resulting in corneal thinning or even perforation,with neovascu- larization.The corneal lesions in 4 eyes were within 1 quadrant,10 eyes within 2 quadrants,6 eyes within 3 quadrants,and 2 eyes in 4 quadrants.Eight eyes of 5 cases,whose corneal lesions were thinner than 2/3 of normal corneal thickness,received 1% cyclosporine A and 0.5% heparin eyedrops.Among those,the lesions in 3 eyes of 2 cases progressed worse.Fourteen eyes of 9 cases,whose corneal lesions were thicker than 2/3 of normal corneal thickness,received marginal lamellar keratoplasty.Among those,recurrent signs were noted in 10 eyes of 6 cases.Conclusions Rheumatic diseases associated corneal melting has typical clinical features.Local cy- closporine A and heparin treatment are effective for patients in early stage.A high recurrent rate is found for patients in late stage re- ceived marginal lamellar keratoplasty.

Objective To determine the protein and mRNA levels of interleukin-17 (IL-17) in the peripheral blood of patients with systemic lupus erythematosus (SLE), and to analyze the relationship between IL-17 and disease activity. Methods Twenty-six hospitalized SLE patients and twenty-one normal controls were studied. Plasma protein and mRNA of IL-17 in peripheral blood were measured by ELISA and Real-time RT-PCR respectively. Results IL-17 level and its mRNA level increased in SLE patients compared with that in normal controls. Plasma concentration of IL-17 showed a significant positive correlation with SLEDAI score and anti-dsDNA antibody level, and a significant negative correlation with serum C3 level. Conclusions Plasma IL-17 protein and mRNA expression level in SLE patients increased significantly and had close relationship with disease activity, which might suggest that IL-17 play an important role in the pathogenesis of SLE.

Objective To study the multi-slice spiral CT (MSCT) perfusion imaging in evaluating the changes of blood supply of hepatocellular carcinoma( HCC ) before and after transcatheter hepatic arterial chemoembolization (TACE). Methods Before and after TACE, MSCT perfusion was performed in 17 patients with HCC. The perfusion indexes such as hepatic blood flow (HBF), hepatic blood volume(HBV),mean transit time (MTT),hepatic arterial fracture (HAF),permeability surface (PS), hepatic artery perfusion (HAP), portal venous perfusion (PVP) were calculated. The hemodynamic changes of HCC after TACE were evaluated according to perfusion parameters. Results After TACE, HBF,HBV and HAP found in MTT and PS before and after TACE (P > 0.05). Conclusion The parameters of MSCT perfusion imaging( HBF, HBV and HAP) can effectively evaluate the hemodynamic changes of HCC after TACE, and has important value in chnical application.

Objective To evaluate the application of combination of BOLD-fMRI and diffusion tensor tractography (DTT) in pre-operative evaluation of cerebral tumors located at the left language related areas.Methods A non-vocal button pressing semantic judging paradigm was developed and validated in 10 right-handed volunteers at 3 T.After validation, this protocol combined with DTI were applied to 15 patients with left cerebral tumor prior to surgical resection, and 3 of them had aphasia fMRI data analysis was on subject-specific basis by one-sampled t-test.The distance from the tumor to Broca area and pre-central "hand-knot" area were measured separately.Functional language laterality index (LI) was calculated by taking out Broca area and Wernicke area.Three dimensional architecture of frontal lobe white matter fibers, especially arcuate fasciculus, were visualized using diffusion tensor tractography on Volume-one software.The images demonstrating relationship among tumor, language activation areas and white matter fibers were reviewed by neurosurgeons as part of pre-operative planning.One year after the operation, patients were followed up with MRI and language function test Results The non-vocal semantic judging paradigm successfully detect Broca area, Wernicke area and pre-central "hand-knot" area In 12 of 15 patients, the relationship of Broca area and pre-central motor area to the left brain tumor in language related areas was identified, which make the pre-operative neurosurgical plan applicable to minimize the disruption of language and motor.8 patients had the left language dominant hemisphere, 3 patients with the right language dominant hemisphere and 1 patient with bilateral dominance.The other 3 patients' fMRI data were corrupted by patients' motion.Diffusion tensor images were corrupted by motion in 1 patient but demonstrated the impact of tumor on left arcuate fasciculus in 14 patients.Diffusion tensor tractography showed disruption of left arcuate fasciculus in 3 patients, deviation/deformation in 6 cases and unaffected by tumor in the remaining 5 cases.Pre-operative review of language activation maps and diffusion tensor tractography of arcuate fasciculus influenced the surgical approach in all 12 patients.Post-operatively, one patient died accidentally, the remaining 14 patients showed no tumor recurrence after one year follow-up.No patient showed deterioration of language function, though 3 patients who had aphasia pre-operation improved slightly.Conclusion The combination of fMRI and diffusion tensor tractography is helpful for identifying the relationship of brain tumors with language cortex and white matter fibers, which is important for sparing language function during individually surgical plan.
