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 investigate the changes in common chemical signal molecules of neuroendocrine-immune (NEI) network and intervention of Tongxinluo (TXL, ultramicro-pulverization) of rats under hypoxia qi-asthenia condition. Methods: Forty-five male Wistar rats were randomly assigned to the following groups: control group, qi-asthenia model group and TXL group (n=15). The rats in the former 2 groups were gavaged with CMC-Na (10 ml/ kg) once daily; those in the TXL group were gavaged with TXL (ultramicrot-pulverization) suspended in CMC-Na (10 ml/kg) once daily; After gavage, animals in the qi-asthenia model group and TXL group were placed in a cabin with normal pressure hypoxia (7 h daily, 6 d weekly for 5 weeks). At the end of the experiment, the biological characters of rats were observed and arterial blood gas was analyzed. The serum contents of serotonin (5-HT), norepinephrine (NE), epinephrine (E), dopamine (DA) and IFN-γ and TRH level in the hypothalamus were examined by enzyme linked immunosorbent assay (ELISA); the serum contents of corticosterone (Cort), T3,T4,IL-1β,TNF-α, and corticotropin release hormone(CRH) in the hypothalamus, and adrenocorticotropic hormone/thyroid stimulating hormone(ACTH/TSH) in the hypophysis cerebri were examined using radio-immunity method. Results: Compared with control group, the biological character scores of rats in the qi-asthenia model group were significantly bigher(P
