Objective To detect the expression of serum soluble E?cadherin(sEC)before and after operation in breast cancer patients,and to ex?plore its clinical significance. Methods The levels of sEC in 42 patients with breast cancer and 18 patients with benign breast diseases were tested by enzyme?linked immunosorbent assay(ELISA)before and after operation as well as in 30 healthy controls. Its correlation with clinical and patho?logical characteristics was analyzed. Results The levels of sEC in breast cancer patients before operation were significantly higher than patients with benign breast diseases and controls,which declined significantly after operation. Moreover,the levels of sEC in those with high clinical grading and lymphatic metastasis were also higher than in the ones with low grading and negative lymphatic metastasis(P<0.05). Conclusion The levels of sEC in breast cancer patients before operation are specific and closely related with pathological grade and lymphatic metastasis,which may be a pre?dictive factor for prognosis of breast cancer.

Objective Toinvestigatetherelationshipbetweendifferenttypesofinternalwatershed infarctionandtandemstenosesofinternalcarotidartery(ICA).Methods Atotalof55patientswith internal watershed infarction confirmed by head MRI and diffusion-weighted imaging (DWI )examination were enrolled. They all underwent the extracranial internal carotid artery (ICA ) ultrasonography and intracranial cerebral artery MR angiography (MRA)examinations. According to the findings of imaging,the 55 patients with internal watershed infarction were divided into a simple internal watershed infarction (IWSI)group and an internal watershed infarction accompanied with ipsilateral cortical watershed infarction (C-IWSI)group. The relationship between the two types of internal watershed infarction and tandem stenoses of ICA was analyzed. Results (1 ) Of the 55 patients with internal watershed infarction,24 cases (43. 6%)were in the internal watershed infarction group and 31 cases (56. 4%)were in the C-IWSI group. The ipsilateral vascular stenosis were ICA 20 cases (36. 4%,including extracranial segment 11 cases and intracranial segment 17 cases),middle cerebral artery (MCA)44 cases (80. 0%), and tandem stenoses of ICA 15 cases (27. 3%). (2)Ipsilateral tandem stenoses of ICA:2 cases were in the IWSI group (intracranial ICA+MCA 2 cases);13 cases were in the C-IWSI group (extracranial ICA+intracranial ICA +MCA 4 cases,extracranial ICA + intracranial ICA 1 case,extracranial ICA + MCA 2 cases,and intracranial ICA+MCA 6 cases). (3)Compared with the IWSI group,the incidences of ipsilateral ICA stenosis and tandem stenoses of ICA in patients of the C-IWSI group were higher (54. 8%[n=17]vs. 12. 5%[n=3],41. 9%[n=13]vs. 8. 3%[n =2]),and there were significant differences(P =0. 001, 0.006]). The incidences of extracranial and intercranial ICA stenosis were higher than those of the IWSI group (35. 5%[n=11]vs. 0,45. 2%[n=14]vs. 12. 5%[n=3]),and there were significant differences (P=0.003,0.009).Conclusion Inthedifferenttypesofinternalwatershedinfarction,theincidenceof tandem stenoses of ICA is different. The IWSI patients with ipsilateral cortical watershed infarction often accompany by tandem stenoses of ICA.

The present paper proposed a central-driven structure of upper limb rehabilitation robot in order to reduce the volume of the robotic arm in the structure, and also to reduce the influence of motor noise, radiation and other adverse factors on upper limb dysfunction patient. The forward and inverse kinematics equations have been obtained with using the Denavit-Hartenberg (D-H) parameter method. The motion simulation has been done to obtain the angle-time curve of each joint and the position-time curve of handle under setting rehabilitation path by using Solid Works software. Experimental results showed that the rationality with the central-driven structure design had been verified by the fact that the handle could move under setting rehabilitation path. The effectiveness of kinematics equations had been proved, and the error was less than 3° by comparing the angle-time curves obtained from calculation with those from motion simulation.

Objective To investigate ultrasonographic features of primary and metastatic ovarian yolk sac tumors.Methods Ultrasonographic features of 19 primary lesions and 33 metastatic lesions in 35 patients were retrospectively analyzed.Results Primary tumors were sized (14.6±3.6)cm in maximum diameter,manifesting as cysti-solid masses.Solid components of primary tumors were mainly hypoechoic or isoechoic(16/19)with rich blood supplies.Thirty-three metastatic lesions were located in pelvoceliac cavity(26/33) and liver parenchyma(7/33),sized (9.4±4.5)cm,(9.2±4.9)cm and (5.6±1.6)cm in maximum diameter respectively.Metastatic lesions in pelvoceliac lesions mainly demonstrated as hypoechoic masses(21/26), however lesions in the liver were mainly hyperechoic(5/7).Anechoic regions could be found in 9/26 of the pelvoceliac lesions.Blood supply was found less rich in metastatic masses than that in primary ones.Elevated serum level of alpha fetoprotein (AFP) was observed in all patients; ranging from 217 to 211 682 μg/L.Conclusions Primary and metastatic lesions of ovarian yolk sac tumor have obvious ultrasonographic characteristics.Combined with serum AFP level,the accuracy of diagnosis could be improved.

Objective To explore the best way to diagnose and cure the nephrosis with ureteropelvic junction obstruction(UPJO) in children.Methods The diagnosis of 26 cases of nephrosis with UPJO were confirmed by ultrasonogram and IVU examinations.All patients underwent AndersonHynes procedures.These results were analyzed and summarized.Results All the diagnosis were proved to be correct by operation and pathology examinations,the operations were carried out successfully.Twenty-four cases were followed up for 6 months to 2 years.After the operation,the hematuria,urinary frequency,abdominal mass and distention disappeared,the urine analysis was normal,all cases cured clinically.Ultrasonogram examinations showed the thickness of parenchyma increased and the large kidneys lessened.Significantly improved renal fuoction on IVU examinations was observed in the 24 cases compared with that before the operations.The ureters of 20 cases displayed well.Conclusions The combination of ultrasonogram and IVU is very effective method to diagnose UPJO in children.Anderson-Hynes technique is the best procedure to cure the UPJO.

OBJECTIVE To know the clinical antibacterial use by line category in pediatric outpatients and emergency departments.METHODS The antibacterial use by line category from the 38998 prescriptions of pediatric outpatient and emergency departments of a hospital from Jul 1st to Dec 31st 2008 according to the medicament amount and frequency were surveyed and analyzed.RESULTS First-line antibacterial drug DDDs accounted for 37.4% and 24.7% of the total amount;second-line drug DDDs accounted for 48.7% and 40.8% of the total amount and the third-line drug DDDs accounted for 13.9% and 35.0% of the total amount.The top three by total amount were cefmetazole sodium injection,azithromycin sodium injection and Cefuroxime sodium injection.According to the sorting method of DDDs,the top three were cefprozil dry suspension,azithromycin sodium injection and amoxicillin sodium clavulanate potassium injection.CONCLUSIONS Frequency of the third-line antibacterial drug using is relatively high.Clinicians have a tendency to skip a line category in using drugs.Effective measures should be taken to strengthen the management of antibacterials.

ObjectiveTo analyze the mental health level and the correlative factors of elderly reflux esophaditis patients.Methods86 elderly reflux esophagitis patients were tested with Symptom Check List-90 (SCL-90) and the Correlative Factor Inquiry List.ResultsThe total SCL-90 scores of the patients was 137.5±27, the number of symptomatic items was 29.9±17, which was significantly higher than that of domestic norm ( P<0.01). Besides of psychopathic and phobic, other factor scores of SCL-90 were also significantly higher than that of domestic norm ( P<0.05~0.01). The somatization, depression and anxiety were first three factors according to significant level. The constitution of patients showed the normal distribution at the level of total SCL-90 score.ConclusionMental health level of elderly reflux esophaditis patients is lower than that of normal people. The two primary reasons are long-term trend and stress of disease.
