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.

Objective To study the effect of serum contained Erzhi Tiangui Granule on the secretion function of ovarian granulosa cells from primary senile mice. Methods The serum with decoction from primary senile mice was added to cultured granulosa cells and incubated for 48 h. Then the concentration of estradiol (E2), progesterone (P) and inhibin B (INHB) in cultured medium were measured by chemiluminescence immunoassay (CLIA) and Sandwich ELISA respectively. Results The serum contained Erzhi Tiangui Granule could increase the secretion of E2, P and INHB. Conclusion Erzhi Tiangui Granule can improve the ovarian function of primary senile mice by regulating the secretion function of granulosa cells.

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.

A solid-phase radioimmunoassay (RIA) method was developed for detection of HBsAg. Its reprodu-cibility. sensitivity and specificity were evaluated, and these results were compared with the Abbott kit (AUSRIA).Horse anti-HBs was used both for coating solid phase and iodination. Normal horse serum was applied in the labelled antiserum to prevent the non-specific reaction between different species of animal sera.The cutoff was 2.21? negative control value. The factor 2.21 was derived from the mean S/N value and its 3 SD of 553 normal sera, while the factor of AUSRIA was 2.1. The lowest detectable amount of HBsAg by our RIA method was 4. 1ng/ml, while that by AUSRIA 2. 1ng/ml, which was about 2 times more sensitive than our system.The prevalence of HBsAg in normal population detected by this RIA ranged from 12.9 to 17.7%. that in the patients with acute viral hepatitis was 60.6%. and in chronic viral hepatitis patients 89.9%.As hepatitis B virus infection is quite common in our country, it is important and urgent to use RIA widely to detect HBsAg carrier in the clinical diagnosis, selection of donors and epidemiological investigation.

Objective To discuss the effect of health education to family members of patients with chronic heart failure. Methods 150 patients with family members as accompanies were divided into the observation group and the control group with 75 patients in each group. Health education was given to patients as well as their family members in the observation group, while health education was given only to the patients in the control group. The mastering of disease-related knowledge by family members of the observation group was observed after 15 days. The rehospitalization of the two groups by telephone follow-up was carried out six months after discharge. Results The mastering of disease-related knowledge by family members of the observation group was better compared with before health education. The rehospitalization rate of the observation group was 13.3%, which was lower than 44.0% of the control group. Conclusions Health education to family members of patients with chronic heart failure can increase treatment effect of patients, decrease disease relapse and lower rehospitalization rate.

ObjectiveTo study the possibility of differentiation of human umbilical cord mesenchymal stem cells(HUCMSCs) into human male germ cells,and to explore a new source of cells for the treatement of male infertility.MethodsHUCMSCs were transplanted into the seminiferous tubules of the testis of infertile mice by microinjection.The survival rate,migration and germ cell markers of HUCMSCs in the mice testis were detected via immunohistochemistry,immunofluorescence and confocal laser scanning. ResultsHUCMSCs can survive in the mice testis for at least 120 days,and they can migrate from the lumens to the basement membrane.Immunofluorescence showed that HUCMSCs can further differentiate in the mice testicular environment,and express the germ cell marker.ConclusionsHUCMSCs can survive,migrate and differentiate into early male germ cell-like cells in the infertility mice testis after transplantation.
