Objective To analyze the correlation of serum hs‐CRP and IL‐6 levels with cerebral hemorrhage volume and nerve function damage .Methods One hundred and two cerebral hemor‐rhage patients served as an experimental group and 64 individuals undergoing physical examina‐tion served as a control group in this study .The patients in experimental group were further di‐vided into mild damage group (n= 29) ,moderate damage group (n= 42) ,severe damage group (n=31) ,10 ml hemorrhage group(n=15) ,10 -30 ml hemorrhage group (n=52) ,and >30 ml hemorrhage group (n=35) .Their serum hs‐CRP and IL‐6 levels were measured on days 1 ,5 ,10 and 15 after admission .Results The serum hs‐CRP and IL‐6 levels in experimental group in‐creased gradually in the first 5 days ,reached their peak on day 5 and then decreased gradually (P<0 .05) .The serum hs‐CRP and IL‐6 levels were significantly higher in severe damage group than in mild and moderate damage groups ( P<0 .05) ,and in experimental group than in control group (9 .46 ± 1 .26 mg/L vs 4 .24 ± 0 .94 mg/L ,P=0 .02) .Conclusion The serum hs‐CRP and IL‐6 levels are related with cerebral hemorrhage volume and nerve function damage ,and can thus be considered as an important parameter in clinical testing .

OBJECTIVE To investigate the expression of keratinocyte growth factor(KGF)in middle ear cholesteatoma and to explore the role of KGF on the hyperproliferation of the cholesteatoma epithelium and the formation and development of cholesteatoma. METHODS The specimens from the cholesteatoma tissue of 20 cases and the corresponding normal external ear skin were examined by immunohistochemical S-P method and quantitative analysis. RESULTS In normal ear skin only stroma staining for KGF was positive. In cholesteatoma epithelium staining for KGF was strongly positive and the stroma staining was stronger than that of normal ear skin. The positive rates of the cholesteatoma and normal external ear skin revealed a significant difference. There was a positive correlation between cholesteatoma epithelium staining for KGF and for Ki67 and the coefflcient of correlation was 0.609(P﹤0.01). CONCLUSION There was correlation between the expression of KGF or Ki67 and the ability of reproduction of middle ear cholesteatoma. Local inflammation might promote hyperproliferation of the epithelium of cholesteatoma by regulating the expression of KGF. It suggested that an autocrine stimulation of KGF correlate with the occurrence and development of cholesteatoma .

Objective To compare the results of 3 methods to treat complete dislocation of acromioclavicular joint. Methods Three different surgical techniques were employed: Dewars procedure (in Group A of 32 cases),tension band wiring (in Group A of 44 cases), and Wolter plate fixation (in Group A of 20 cases). There were 81 males and 15 females, or totally 85 cases of acute dislocation and 11 chronic dislocation. Results 96 cases were followed up with an average period of 50 months. Acording to karlssons standards, in group A, 26 patients were assessed as good, 5 as fair and 1 as poor. In group B, 20 patients were assessed as good, 13 as fair and 11 as poor. In group C, 15 patients were assessed as good, 4 as fair and 1 as poor. There were differences between A and B, C and B. But there werent statistic differences between A and C. Conclusion The Dawers procedure is believed to be a good, simple and safe method to treat acromioclavicular joint dislocation, with no need of a second operation to remove the implant and with less complications.

The finding and research on yeast prion are of great values for biology and medical sciences.Research advances in molecular chaperones, especially in Hsp104p, Hsp70p and Hsp40p, regulating yeast prion [PSI+] propaga-tion,are reviewed.

Multiplicity of signals and diversity of signaling pathways exist during the establishment of mycorrhizal associations together with the regulation of symbiosis-specific genes expression.This mechanism of signal recognition and transduction related with development process of the symbiont was reviewed at the molecular level.

Impotence is one of the more common and serious symptom type of male sexual disturbance.It demonstrates by domestic sampling investigation that about more than 10% of male adult have impotence,and the incidence of impotence goes higher with the growing of age.Warming and invigorating kidney-yang has been the main therapy method for treating impotence.Through years of clinic practices,the treatment for impotence from liver has achieved satisfied effects.

The identification and classification of Thermus to Thermales is revie wed. Up to now, the order Thermales is consist of only one family Thermaceae, w h ich includes 4 genera with 14 valid species about 50 strains, and with 4 unvalid spcecies and more than 50 strains unidentified. The morphology, physiology, G+ C mol%, DND hybridization, fatty acid components, 16S rRNA alignment and secondar y structure analyses have been tools for the taxonomy of Thermales.

Objective To study the inhibition effects of 10-hydroxycamptothecinc and low molecular weight heparins on human hepatocellular carcinoma(HCC)in nude mice.Methods Metastatic model of HCC was established in nude mice.The model mice were randomly divided into 4 groups:the control group,10- hydroxycamptothecinc group,low molecular weight heparins group,and combined treatment group(10-hy- droxycamptothecinc and low molecular weight heparins).Tumor sizes,tumor inhibition rates,tumor metas- tases,intratumoral microvessel density(MVD),CD_(31)and AFP were evaluated.Results In comparison with the control group and the 10-hydroxycamptothecinc group,the tumor sizes of the low molecular weight heparins and the combined treatment group were significantly smaller;the tumor inhibitor rates were 0 versus 76.6%, 79.8%,94.1%;MVD were 21.1?6.5 versus 17.2?3.1,7.1?2.3 and 4.8?1.8;CD_(31)were 31.7?6.1 versus 26.2?5.2,20.9?4.7 and 19.5?2.4;the incidence of liver metastasis was 80% versus 70%,20% and 10%;lung metastasis was 70% versus 60%,20% and 10%;the peritoneal metastasis was 90% versus 60%,30% and 30%.AFP were(121.9?31.4)ng/ml versus(56.2?37.9)ng/ml,(75.6?28.7)ng/ml and(20.7?12.9)ng/ml. Inhibiting effects of growth and metastasis of HCC in 10-hydroxycamptothecinc group,low molecular weight heparins group and combined treatment group were significantly different from those of the control group(F= 9.074,P

Objective To construct the endothelial cell model with overexpressed human protein kinase C ?2(PKC?2) after high glucose inducement in order to study the function of human PKC?2. Methods The PRKCB1 gene was amplified from pMD18-T-PRKCB1 plasmid and then directly cloned into shuttle plasmid pDC315 to construct shuttle plasmid. Then the recombinant shuttle plasmid and adenovirus genomic plasmid pBHGlox△E1,3Cre were cotransfected into 293 cells to construct recombinant adenovirus Ad-PRKCB1. The virus titer was calculated by TCID50. The Ad-PRKCB1 was verified by immunocytochemistry and RT-PCR. Ad-PRKCB1 was transfected into human umbilical vein endothelial cells (HUVECs) followed by the treatment of high glucose (25 mmol/L) for 96 h, and then the cells were observed by laser scanning confocal microscopy (LSCM). Results Restrictive endonuclease digestion and PCR result showed that the target gene was correctly cloned into shuttle plasmid. Cytopathic effect (CPE) was observed under inverted microscope through homologous recombination. The virus titer was 7.9?109 IU/ml. Immunocytochemical staining and RT-PCR indicated the expression of human PKC?2 in the transfected HUVECs. The translocation was observed under LSCM. Conclusion A recombinant adenovirus vector with human PKC?2 and the endothelial cell model with human PKC?2 overexpression by high glucose are constructed successfully.
