Ductal carcinoma in situ belongs to the early stage of breast cancer.The treatment of ductal carcinoma in situ is similar with that of the breast cancer.Because of the low mortality rate in patients with ductal carcinoma in situ,there was an excessive treatment in the treatment of ductal carcinoma in situ.So the key to the treatment of ductal carcinoma in situ was to improve the quality of life.The present study shows that the effect of conserving surgery with radiotherapy is same with mastectomy's in the treatment of breast ductal carcinoma in situ.Sentinel lymph node biopsy can also be used to evaluate the patient's axillary status.For patients with ductal carcinoma in situ with breast conserving surgery,radiotherapy and endocrine therapy can reduce the recurrence rate of ipsilateral breast cancer.Radiotherapy and endocrine therapy have also become the standard treatment for ductal carcinoma in situ.

Dystonia is common in children with cerebral palsy. It can cause motor dysfunction, and is frequently associated with altered speech articulation, abnormal swallowing, and excessive drooling. Although trihexyphenidyl (Artane) is an anticholinergic agent with a long history of use in the management of dystonia in adults, information is limited regarding the use of trihexyphenidyl in children. This study reviewed the clinical experience of the use of trihexyphenidyl in children with cerebral palsy for dystonia, with special emphasis on benefits and tolerability.

Dendritic cells(DCs) are known as the most efficient antigen-presenting cells that are potent stimulators of both B and T cell immune responses.The biological characteristics and culture in vitro of DCs,preparation of DC vaccines,experimental and clinical studies in tumor immunotherapy by DC vaccines are reviewed in this article.

Objective To investigate the relative factors of insulin resistance(IR)during elective abdominal surgery and the mechanism of IR induced by surgery.Methods Fourteen patients underging elective abdominal surgery were studied.Fasting blood glucose(FBG),fasting plasma insulin(FPI),plasma TNF-α,IL-6 and CRP were tested for elective surgery patients on the day before,during operation and on one day after surgery.Insulin resistance index(HOMA-IR)and the index of insulin secretion(HOMA-β)were ealculated with homeostasis model assessment(HOMA).Insulin receptor and GLUT4 mRNA expression in skeletal muscle were assessed before operation and at the end of operation by use of RT-PCR.Results Significant differences were found in fasting blood glucose (5.95±1.08)mmol/L vs(8.92±2.41)mmol/L,fasting plasma insulin(19.95±3.33)mU/L vs(25.44±5.36)mU/L,IL-6(33.98±5.01)ng/L vs(45.29±7.81)ng/L and plasma TNF-α(86.70±9.27)ng/L vs(114.46±15.33)ng/L during and after operation(P＜0.01).A significant elevation of HOMA-IR levels was found after operation compared with that before operation[(9.59±2.89)vs(4.111.86)](P＜0.001).However there wag no significant difference in HOMA-β among three points(groups)of time(P=0.103).The result of RT-PCR showed that the expression of GLUT4 in muscle of patients at the end of operation reduced significantly compared with preoperation(t=12.488,P＜0.001)but there was no significance in INSR mRNA expression(P=0.165).ISI showed negative correlation with opermive time(r=-0.736、P＜0.001),blooding during operating (r=-0.594、P=0.032)and post-operative TNF-α(r=-0.641、P=0.018).Conclusion Insulin resistance occurs in elective abdominal surgery patients.The defective site is at postreceptor.To shorten the operation time,control the intensity of surgery and reduce the bleeding is helpful for decreasing IR.

Objective To explore the diagnostic value of spiral CT for the intestinal obstruction of unknown causes.Methods The CT findings of 115 intestinal obstructive patients with unknown causes were analyzed retrospectively.Results Of the 115 patients,the diagnosis of intestinal obstruction was comfirmed by CT in 110 cases patients,the correct diagnostic rate was 95.7%.Conclusions Abdominal CT is a rapid、simple and effective means for diagnosis of the location、cause and degree of obstruction in cases of intestinal obstruction with unknown cause.It can act as an important basis for the treatment program by doctors.

During spermatogenesis, lysine-rich histones in spermatogenic cells are progressively replaced by arginine-rich protamine. In this study, the nucleoprotein transition in spermatogenic cells of Wistar rat was investigated using aniline blue staining, PTA staininig (both to demonstrate lysine-proteins) and NQS (1, 2-naphthoquinone4-sodium sulfonate) staining (to demonstrate arginine-protein). Under light microscope, the nuclei of spermatogonia and spermatocytes were intensely aniline blue positive and the nuclei of young spermatids moderately positive, while the nuclei of late elongated spermatids and spermatozoa were aniline blue negative. The nuclei of spermatogonia and young spermatids were basicallyy NQS negative and there were a few granules of weak NQS positive in the nuclei of primary spermatocytes, while the nuclei of late elongated spermatids and spermatozoa were NQS positive. Under the electron microscope, the PTA positive chromatin in the nuclei of early spermatids with round nucleus (steps 1 to 8)was fibrillar or granular in appearance. Along with the condensation of nuclei of spermatids(steps 9 to 13), the nuclear stain ability increased. The positive chromatin in the nuclei of spermatids (steps 14, 15) was disappeared progressively, in the direction from cranial to caudal along with the further condensation of nuclei. The nuclei of late spermatids with elongated nucleus (steps 18, 19) and spermatozoa were PTA negative. These observations suggest that the nucleoprotein transition from histones to protamine (S_1) occur during spermiogenesis and that this process could be divided into two consecutive steps, i. e. from histones through an intermediate phase of transition proteins to protamine.

Objective To research the visualization of congenital heart disease by three-dimensional echocardiographic(3DE) virtual endoscopy(VE) system. Methods Datasets.from 10 healthy children and 22 patients with congenital heart disease were collected (10 patients with atrial septal defects, 6 patients with ventricular septal defects and 6 patients with tetralogy of Fallot). 3DE heart models were reconstructed by virtual reality computing techniques and visualization in scientific computing techniques. The VE system was programmed under the C++ 6.0 language condition,the visualization toolkit (VTK) platform was employed to carry out the graphics and visualization utilities. The virtual eye can move along the navigation paths in the heart by manual camera movements. Results The VE can provide special information in aspects of intracardiac anatomy, The visible heart models show precisely complex anatomy structure and spatial relationships. 3DE intracardiac endoscopic imaging can thus be visualized and navigated successfully by the VE system. Conclusions 3DE VE is a new system for the visualization of congenital heart disease.

Objective To investigate the relation of the peripheral blood C-reactive protein (CRP)and procalcitonin (PCT) and multiple organ dysfunction syndrome( MODS ) for patients with multiple trauma.Methods A total of 136 patients with multiple trauma were divided into MODS group (49 cases) and non MODS group (87 cases),and 50 healthy volunteers were chosen as control group. Peripheral blood CRP and PCT concentration were detected at different times. Results The highest concentration of peripheral blood CRP in MODS group was appeared on 48 h [(38.7 ± 2.7) mg/L], CRP concentrations in MODS group were significantly different with non MODS group and control group (P ＜0.05). The highest concentration of peripheral blood PCT in MODS group was appeared on 24 h [(20.3 ± 1.7)μ g/L], PCT concentrations in MODS group were significantly different with non MODS group and control group (P＜ 0.05). Conclusions CRP and PCT are relevant to the occurrence of MODS in trauma acute stage. The observation of peripheral blood CRP and PCT concentrations can predict the occurrence of MODS.
