Objective To investigate the clinical values of loop electrosurgical excision procedure (LEEP) in diagnosis and treatment of cervical intraepithelial neoplasia(CIN). Methods Fifty-two patients with cervical intraepithelial neoplasia underwent LEEP following cytology, colposcopy and multiple biopsies, were treated by LEEP. The cure rate, the operative time, bleeding volume and patients reaction of LEEP to the cervical intraepithelial neoplasia were investigated during the follow-up. Results The effective rate was 98.07 % in the patients treated by LEEP. The effective rate was 100 % in the patients in grade CIN Ⅰ or CIN Ⅱ by LEEP. No patients in grade CIN Ⅰ and Ⅱ had recurrence during the follow-up 1 year. The mean operative time was 7.8 minutes. The mean bleeding volume was 10 ml. No secondary bleeding and post-operative infection occurred. All these surgical specimens were checked successfully for pathology diagnosis. Conclusion The advantages to use the LEEP to manage cervical intraepithelial neoplasia include its simpleness to handle, short operative time,less bleeding, less vaginal discharge, safety, and high cure rate. LEEP can offer intact sample for pathological diagnosis. LEEP electrotome is a very ideal therapy for the cervical intraepithelial neoplasia, and can block the development of precancerosis to infiltrating carcinoma effectively.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by the accumulation and proliferation of inflammatory cells in the synovial (joint) lining.By investigating RA pathologic processes and also through experimental models where immune complexes (inflammatory sediments) play a fundamental role.Many other autoantibodies have then come to our knowledge to be associated with the disease.Though it remains unknown the autoimmune pathology of B cells and why the clones of autoreactive B cells survive and proliferate in RA patients,but no doubt these autoantibodies represent a very useful tool in both diagnostic and prognostic terms.In joint synovial fulid,B cells also secrete cytokines,which can be interacted with other cells.B cells express IL-13 receptor a1 (IL-13Ra1),IL-13 can induce CD23 expression on B cells and promote proliferation of naive B cells. In addition,IL-13 is a cytokine which is produced mainly by activated T helper cell 2 (Th2 cells),it can inhibit the production of pro-inflammatory factor and chemokines,and has a certain relationship with the differentiation of B cells. Therefore,it is necessary to summarize the mechanims of RA pathogenesis related with B cells and IL-13,which has great significance in the diagnosis,treatment and basic immunology research of autoimmune diseases such as RA.

Objective To evaluate prognostic indicators in severe traumatic brain injury and intracania hamatomas with hernia and analyze which is the most important indicator.Methods Data of 84 cases with severe traumatic brain injury were retrospectively analyze .Age,GCS,pupil reflex,midline shift,compression of the cisteme,decompression time and complex injury were considered as possible prognostic indicators.SPSS13.0 was employed to analyze the data,Logistic regression(Forward conditional)analysis was done to confirm which are the most important prognostic indicators for severe traumatic brain injury and to evaluate the practical value in predicting prognosis(X2= 22.92,P＜ 0.01).Results 48 patients died and 36 survived.56(67%)patients had a bad prognosis(GCS≤3)and 28(33%)had a good prognosis(GCS ＞3).Those who had a shorter decompression time(≤3h)had a better prognosis than those who had a longer decompression time(＞3h),with the mortality rate of 11% and 67% respectively.Lesser cisteme compression predicts better outcome.GCS,pupil reflex,midline shift,and complex injury didn' t enter the logistic regression equation.According to compression time,90.5% of the cases' prognosis was accurately predicted,according to compression time and cisterne compression,95.2% was accurately predicted.Conclusion The mortality rate of severe traumatic brain injury with hernia was high and surgical intervention was effective.Decompression time and cisteme compression were the most important factors affecting prognosis in severe traumatic brain injury and they could predict prognosis of most cases correctly.

Background Choroidal neovascularization (CNV) is one of the primary causes leading to visual damage in many fundus diseases.Many evidences indicate that macrophage activation and monocyte chemoattractant protein-1 (MCP-1) play important roles in CNV.However, the dynamic expression of macrophage and MCP-1 in the initial stage of CNV is not clear.Objective This study was to investigate the dynamic changes of F4/80 and MCP-1 expressions in retina-choroid tissue with experimental CNV.Methods Laser-induced CNV models were monocularly established in 105 SPF 8-week-old male wild type C57BL/6 mice.The mice were sacrificed at 6,12,24, 48 and 72 hours after photocoagulation, respectively, and the retina-choroid tissue sections and choroidal flatmounts were prepared.The histopathological examination was carried out to observe the changes of morphology and structure as well as inflammatory response in CNV.The expression and distribution of F4/80 and MCP-1 protein in retinachoroid were detected by double immunofluorescence technique.The expression and distribution of F4/80 in choroid were examined by immunofluorescence.The relative expression levels of F4/80 mRNA and the content of MCP-1 protein in RPE-choroid complex were assayed using real-time quantitative PCR and ELISA,respectively.The use and care of the mice complied with the Regulation for the Administration of Affair Concerning Experimental Animals by Ethic Committee of Experimental Animals of Nanjing Medical University.Results The rupture of Bruch membrane, RPE, outer nuclear layer and choroid was exhibited under the optical microscope 6 hours after photocoagulation.Infiltration of inflammatory cells and tissue edema were seen as the lapse of photocoagulation time, and proliferation of vascular endothelial cells was found 72 hours after photocoagulation.F4/80 was expressed in photocoagulation area 6 hours later, and MCP-1 was expressed around the area.With the lapse of photocoagulation time,the expression intensity of MCP-1 weakened and that of F4/80 enhanced.The contents of MCP-1 protein in RPE-choroid complex were (31.25±4.73), (276.31 ±4.20), (331.95 ±5.86), (221.24±4.42), (179.89 ± 4.10) and (130.80 ± 5.90) pg/mg in the normal control group, photocoagulation 6-, 12-, 24-, 48-and 72-hour groups, respectively,with a significant difference among the groups (F=1 416.46 ,P＜0.01).The contents of MCP-1 protein peaked at 12 hours after photocoagulation and then gradually declined.The expression levels of MCP-1 protein in different time groups were higher than those in the normal control group (all at P＜0.01).A significant difference in F4/80 mRNA expression in RPE-choroid complex was also found among the groups (F =762.72, P＜0.01, and a gradually raising tendency was seen over time, showing evidently increase in comparison with the normal control group (all at P＜0.01).Conclusions Inflammatory response occurs in the early stage of experimental CNV.MCP-1 responds to the CNV at early stage,and the accumulation and activation of macrophage play an important role in the development of CNV.

Objective To observe the effect of extract from Branchlets roses on blood glucose and glucose tolerance in diabetes mice induced by alloxan.Methods Diabetes animal model was established by alloxan.Dividing the model mice into eight groups:model group,water extract high,middle,and low dose (3.70,1.85,and 0.93 g/kg) group,and ethanol extract high,middle,and low dose (2.75,1.37,and 0.70 g/kg) group,and metformin (positive drug,200 mg/kg) group,and normal mice were taken as control group.Drug was ig administered to mice 3 d after molding once daily.Blood glucose test paper was used to determine fasting blood glucose 0,10,20,and 28 d after modeling,and the glucose tolerance test was performed 30 d after modeling.Results The extract of Branchlets roses from all the groups could decrease the blood glucose and improve the glucose tolerance,and showed a certain dose-effect relationship.In all the extracts,the alcohol extract had the best effect,but the effect was not as good as the positive control drug metformin hydrochloride group.Conclusion The extract of Branchlets roses can reduce the blood sugar content of diabetic mice,and improve the glucose tolerance.
