Objective　To investigate the biological significance of p185 and p16 in breast cancer. Methods　Immunohistochemical S-P method was used to detect the expression of p185 and p16 proteins in 59 breast carcinomas，and their relations to clinicopathologic features were analyzed. Results　The positive rates of p185 and p16 were 47% and 34% respectively. No significant association was evident between the two proteins. There was also no significant relation between p16 expression and clinicopathologic features. p185 positive rate was 64% in the group of lymph-node involvement that was higher than that being 32% lymph-node negative one (P<0.05). Conclusion　p185 and p16 may play important roles independently in the development of breast cancer through different pathways. p185 detection is of important value in breast cancer.

ObjectiveTo discuss the clinical features, diagnosis and treatment of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome in children.Methods The clinical features and treatment process of two children with MELAS were retrospectively analyzed.ResultsThe main clinical features of MELAS were stroke-like epi-sodes, seizure, visual anomaly and lactic acidosis. Cephalic MRI ifndings performed during episode periods were in accord with the typical radiographic features of MELAS. Gene testing on the two children and their mothers showed the point mutation of A3243G in mitochondrial genome. The symptoms were improved signiifcantly after energy supply and corticosteroid treatment. Conclusions MELAS syndrome is easy to be misdiagnosed due to the varied clinical features. The diagnosis depends on the musclebiopsy and gene testing. Corticosteroid therapy is effective for MELAS syndrome.

The incidence rate of erectile dysfunction (ED) is reportedly as high as 30-90% after radical prostatectomy for prostate cancer, which seriously affects the patients' quality of life. Penile rehabilitation is defined as the use of any drug or device at or after radical prostatectomy to maximize erectile function recovery. A variety of treatment options are available for post-prostatectomy ED patients, including oral phosphodiesterase 5 inhibitors (PDE5I) , intracorporal injections, vacuum erection device, and penile prosthesis. This article presents an overview of the currently used methods for the drug treatment and penile rehabilitation of the ED patients after radical prostatectomy. It seems proper to recommend daily use of a vacuum erection device plus oral PDE5I in the early postoperative period. For those who fail to respond to this therapy, intraurethral alprostadil, intracorporal injections, or a penile prosthesis could be considered.

Objective： To investigate pathophysiologic mechanism about initiation and propagation of epilepsy in a genetically epilepsy-prone rat (GEPR) model. Methods： The hippocampal MF sprouting of P77PMC rats was examined at different stages in the course of recurrent seizures using Timm method of sulfide silver staining. Results：The three groups of P77PMC rats which experienced 30 and less than 30 times of audiogenic seizure ( AGS ) and the Wistar control group did not display MF sprouting in dentate gyrus, however, the group of P77PMC rats which experienced 50 times of AGS was found hippocampal MF sprouting into the inner molecular layer of dentate gyrus. Conclusion：Our findings suggest that hippocampal MF sprouting presented not only in limbic seizure, but also in AGS, the seizure initiated in brainstem but rapidly generalized; in AGS-prone rats, recurrent AGSs can induce MF synaptic reorganization in hippocampus.

Objective To investigate the effect of surgical intervention combined with steroid therapy on infantile hepatitis(INS) with persistent jaundice.Methods Twenty-two patients (19 males,3 females,aged 2-6 months) with persistent jaundice(therapy group) were admitted into hospital in the period of Jan.2007-Dec.2008.The patients were performed with surgical intervention after they were confirmed with diagnosis as INS.Then,sodium chloride,gentamicin and Dexamethasone were used to irrigate the biliary tract during and after the operation for 14 days.Three days after operation,20 mg,15 mg,10 mg,5 mg of methylprednisolone were administered intravenously to the patients every 3 days,followed with 4 mg/(kg?d) prednisone by oral for 2-3 months.The 17 cases of INS with persistent jaundice were treated with medicine as control(control group).By following-up,the jaundice free and 2 years survival rate of 2 groups were compared by counting the cases of jaundice free and recording the survival time.Results Two cases of 22 patients performed with surgical intervention were diagnosed as biliary atresia and others were INS,90.0% patients were free of jaundice in surgical intervention combined with steroid therapy group,which was higher than that in control group(52.9%,P

Objective To study the clinical effect of the combination of cataract ultrasonic emulsification and multifocal aspherical intraocular lens in cataract patients through evaluating different intraocular lenses elimi-nating spherical aberration. Methods 180 patients(180 eyes)with senile cataract were included between,2001 and 2005.The patients were divided into three group (n = 60 each),based on the admition time. Implantion of ReSTOR-SN60D3 is multifocal aspherical intraocular lens(SN60D3),implantion of SN60AT lens is single spheri-cal intraocular lens (SN60AT),and implantion of SN60WF lens is single aspherical intraocular lens (SN60WF group). Three months after operation,the refractive state,focus depth,modulation transfer function(MTF),and higher-order aberrations were measured ,and the visual quality were investigated. Results There was no signifi-cant difference in vision in three groups before operation(P > 0.05). After operation,the UCNVA of SN60D3 group was significantly better than the SN60AT group and SN60WF group(P < 0.05). Under 3 mm pupil diame-ter,spherical aberration of SN60D3 group and SN60WF Z(4,0)were less than SN60AT group(P < 0.05), SN60D3 group and SN60WF only under 5 CPD spatial frequency MTF(HOA)value was superior to the SN60AT group(P<0.05);The score of near vision,reliance on vision correction and limitation of operation of patients in SN60D3 group were higher than other two groups(P<0.05). Visual clarity and day vision fluctuations of patients in SN60D3 group is better than single focal sphere group(P<0.05). Conclusion In multifocal aspherical intra-ocular lens,general spherical aberrations and higher-order aberrations is smaller,effect of naked near vision is bet-ter and the rest of the vision is stable ,which can bring good visual quality for cataract patients after operation.

Objective:To study the effect of overdose fluoride on Smad3 expression during development course of Wistar rat's incisor,and then to explore pathogenesis of dental fluorosis.Methods:20 Wistar rats(10 male rats and 10 female rats)were randomly divided into two groups.Experiment group was feed with water contained 0.1 g/L fluorin and normal group with distilled water was served as control.After 8 weeks all rats were sacrificed.Immunohistochemistry was used to observe the effect of overdose fluorin on Smad3 expression in rat's ameloblast and odontoblast.Results:The immunohistochemistry results demonstrated that in experiment group,Smad3 expression in rat's ameloblast and odontoblast was lower than those in control group,and statistic analysis showed there were significant differences between the two groups(P

Objective To compare two assay methods, namely immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), in the detection of Her-2/neu status in mammary cancer tissues. Methods In 20 samples IHC technique was applied to detect the Her-2 protein in the cytomembrane of mammary cancer, and FISH was used to assess the amplification of Her-2/neu gene, and SPSS 10.0 software was employed to analyze the relationship between the two methods. Results The coincident rate of two methods was 85%, therefore there was a significant positive correlation between the two techniques (?~2=80.00, P=0.00). Conclusion The two assay methods, IHC and FISH showed a good coincidence in the detection of Her-2/neu status in mammary cancer tissues.
