Objective To study the plasticity of hippocampal formation in epilepsy.Methods The optical density (OD)of synaptophysin positive immunoreactive product was examined by image pattern analysis instrument in hippocampus of pentylenetetrazol induced kindling epileptic rats. The examined areas included CA1,CA3 and the dentate gyrus.Results The OD of synaptophysin positive immunoreactive product in hippocampal formation of kindling group was higher than the controls,especially in the mossy fiber layer of the area CA3 and the inner molecular layer in the dentate gyrus. Conclusion The change of synaptophysin resulted from kindling, it also could result in the molecular elements of kindling maintenance.

Objective To investigate clinical results of shoulder hemiarthroplasty in treating comminuted proximal humeral fractures. Methods Shoulder hemiarthroplasty was performed from May 1997 to June 2004 in 28 cases with comminuted proximal humeral fractures who were followed up for mean 2.1 years. American Shoulder & Elbow Surgeon (ASES) score was adopted for evaluating pain after operation, range of active movement and function of daily work. Results Mean ASES score was 87.9(67-96 scores), with mean forward flexion of 132?, external rotation of 40?, mean VAS score of 2.6 and internal rotation at T_ 10 level. Strength and function of 23 cases reached 80% of the normal side six months postoperatively and 90% of the normal side one year postoperatively. Of all cases, 82% were satisfied with the treatment. Conclusion Only reconstruction of normal humeral length, tuberosity fixation and persevering rehabilitation can contribute to a successful result of hemiarthroplasty for the comminuted proximal humeral fractures.

0.05). Radiographic analysis showed quite good results in 77 cases. Complications included delayed union in six cases, severe stiffness in one and neuropraxia in two. Conclusions Open reduction and internal fixation of intracondylar humeral fractures is a safe and effective technique. Meanwhile, triceps-split approach and olecranon osteotomy can obtain same clinical outcome for intracondylar humeral fractures.

Objective To analyze the epidemiological trends of leprosy and evaluate the effectiveness of control in Zhejiang Province. Methods A retrospective study was conducted. Results By the end of 1999, 16 262 leprosy patients had been registered, of them 11 935 had been cured and only 97 were still remained. In 1999, active cases decreased by 99.02% over 1973. The epidemiological trends of leprosy showed the increase of mean age at onset and type ratio, and the decrease of incidence in children. Conclusion The epidemicity of leprosy has been continuously dropping in Zhejiang Province due to the sustained effort and effective control.

ETAN is a marine biomaterial which is made of chitosan,a partially deacetylated derivative of chitin ,and prepared by a foaming technique. The effects of absorbing exudate, stopbleeding,promoting wound healing and biological compatibility were observed in this experiment. The results showed ETAN could promote skin wound healing reduce the scab time of the wound surfaces. Skin tissue was healed quickly after ETAN was coated on wound skin surfaces,and it had marked effects of absorbing exudate,and haemostasis. Its effects were superior to that of gelatin sponge. ETAN could be fused with subcutaneous tisssue embeded subcutaneously two weeks later. The fused skin tissue was returned to normal skin tissue nearly after it was embeded four weeks . These experimental results showed ETAN had a better biological compatibility.

Interleukin 24 ( IL-24) has a good prospect in tumor therapy because it can specifically inhibit proliferation in a variety of tumor cells in vitro and in vivo and induce apoptosis of tumor cells without affecting normal cells .Gene therapies which use recombinant adenovirus as a vector have some limitations that restrict the clinical application of IL-24. In comparison, protein drugs have tremendous advantages .In this paper, the progress in research on IL-24 gene engineering protein is elaborated .

To optimize Chinese hamster ovary (CHO)expression system and establish a process of screening CHO cell lines with high productivity;neomycin-phosphotransferase (NPT)expressed by the resistance marker gene on the expression vector was mutated with amino acid D at 261 changed to G.After selection by culturing with G418;the survival rate of CHO cells bearing mutant-NPT was significantly lower than that of the cells bear-ing wide type NPT.An enhanced green fluorescent protein (EGFP)was genetically linked to the N terminus of the IgG1 Fc fragment part to generate an EGFP-Fc fusion protein regarded as a report gene;which verified that the resistance of mutant-NPT to G418 was weakened.By comparing fluorescence assay of EGFP intensity in stable transfections after selection with the same concentration of G418 for 3 weeks;mutant-selected pools expressed more exogenous protein than the WT-selected pools.Therefore;the ratio of high producers in a transfected cell population greatly increased.

Objective To compare the prevalences of metabolic syndrome(MS)diagnosed with 4 diagnostic criteria by the World Health Organization(WHO,1999),the Inrernational Diabetes Federation(IDF,2005),the Third Report of the National Cholesterol Education Program Expert Panel on Detection,Evaluation and Treatment of High Blood Cholesterol in Adults(NCEP ATPⅢ,2001)and the Chinese Medical Association Diabetes Branch(CDS)respectively. Methods The interrelated parameters were measured in 1399 patients with newly-diagnosed type 2 diabetes mellitus.All the patients were divided into 2 groups:elderly group(259 cases)and non-elderly group(1140 cases),and the different prevalences diagnosed by 4 diagnostic criteria in 2 groups were compared. Results The MS prevalence was 68.0%,47.9%,46.7%and 54.8%in elderly group by WH0,CDS,IDF and NCEP ATPⅢ respectively.The consistent rate was 76.1% between WHO and CDS,and 70.3%between IDF and CDS,and 81.9% between NCEP ATPⅢ and CDS. Conclusions The WHO definition may be more suitable for MS diagnosis in elderly patients with newly-diagnosed type 2diabetes mellitus.

Objective To study the related risk factors of pulmonary embolism(PE) in diabetic patients.Methods 58 diabetic cases were underwent lower limbs 99mTc-MAA veins imaging(and/or ultrasonography) and pulmonary perfusion imaging.The related laboratory data [fasting blood glucose(FBG),blood cholesterol,blood long chain triglycerides(LCT)]and clinial informations [age,disease courses,chest symptoms(chest pain and short of breathe),lower limbs symptoms(swelling,crooted veins and diabetic foot) and acute complication(diabetic ketoacidosis and hyperosmolar non ketotic diabetic coma)]were collected simultaneously.SPSS was used for χ2-test and Logistic regression analysis.Results 28 patients(48.3%) were showed to be with lower limbs deep vein thrombosis (DVT) and by 99Tcm-MAA imaging,10 cases(17.2%) with PE.The PE ratio(32.1%) of the patients with DVT was more higher than no DVT(3.3%)(χ2 = 6.53,P<0.05).Single factor analysis showed the PE ratios had significant difference to factors of chest symptoms,lower limbs symptoms and acute complication(all P<0.05),respectively.There were no significant difference in other factors of age,disease courses,FBG,blood cholesterol,LCT,blood pressure,weight index,DM type(all P>0.05),respectively.Multiplicity analysis indicated:the related risk factors of PE included chest symptoms(Score = 13.316,P<0.01) and lower limbs symptoms(Score = 7.780,P<0.01).There were no significant differences in other factors(all P>0.05),respectively.Conclusion The serious DM with chest symptoms,lower limbs symptoms and/or DVT could be controlled as early as possible by all kinds of treatment.It would decrease the PE complication.
