Objective To investigate antiviral and immunoregulation effects of indole-2,3-dine(ISA).Methods The BHK-21 cell model infected with Sendai virus was established and the antiviral effect of ISA was observed by cytopathic effect(CPE) method;its effect on immunological function was observed by hemagglutination inhibition test using Sendai virus infected mice model.Results ISA showed cytotoxicity when the concentration was above(0.313)mg?mL~(-1),while ISA showed a dose-dependent antiviral effect without cytotoxicity when the concentration was among 0.156~0.039mg?mL~(-1).ISA at higher dose(2%) could accelerate the production of hemagglutination inhibition antibody in hemagglutination test(P

Breast-Specific Gamma Imaging (BSGI) is an improved and optimizing nuclear medicine breast imaging technique on the basis of traditional gamma camera. It uses a high resolution, small field-of-view scintilla detector. The detector is designed with 3 073 individual detector crystals and 48 position-sensitive photomultiplier tubes. The FOV of detector is 15 cm x 20 cm, and optimal system resolution for breast imaging is 3 mm, can detect the diameter of only 2-3 mm small lesions. BSGI has better sensitivity in detecting subcentimetre or nonpalpable breast cancer. The sensitivity for the diagnosis of breast cancer is high, not influenced by the density of the breast tissue, implants, architectural distortion-or scars from prior surgery or radiation. So it is called a high resolution, small field-of-view breast-specific gamma camera.

Objective The relationship between the clinicopathological features and the prognosis of breast cancer patients was evaluated by the expression of EPB41L4A-AS2 in breast cancer tissues.Methods The relationship between the expression of EPB41L4A-AS2 and the clinical features of breast cancer was evaluated by using the genome meta analysis,TCGA and Gene Expression Library(GEO) datasets.The correlation between EPB41L4A-AS2 and apoptotic pathway was verified by Western blotting.Results The results from Meta -analysis,TCGA and GEO datasets showed that EPB41L4A-AS2 was low in breast cancer tissues and was positively correlated with poor clinical and pathological features.EPB41L4A-AS2 was confirmed an association with the classical apoptosis pathway in breast cancer cell lines.In the meta-analysis of GEO,we found the high expression of EPB41L4A-AS2 with good prognosis.Conclusion EPB41L4A-AS2 inhibits tumor formation and has a high value in clinical prognosis of breast cancer.

Objective: To design a convenient and safe leg support of lithotomy position surgical bed. Methods:Put the gas spring in the device to lift and drop the leg support, instead of turning screw, And then use the new leg support in 80 lithotomy position surgeries. Results:The new device can be operated by one man, it is easy operating and labor saving. There was no leg slip occurred in 80 surgeries, operators all expressed satisfaction. Conclusion: This innovation patent solved the problem of toilsome operating and potential safety hazard, It worth widely use in the clinical.

Obiective To realize real-time data processing in lung ventilation reconstruction based on electrical impedance tomography(EIT). Methods The image reconstruction algorithms, plotting functions and matrix calculations are dynamic transferred with Matlab C++, Mathtools and VC++ to meet the requirements of data processing and imaging in real time.Results Image reconstruction and real-time data processing were realized successfully in lung ventilation based on EIT. Conclusion It provides a new strategy for real-time data processing of image reconstruction by EIT.

BACKGROUND:Anterior cervical discectomy and intervertebral disc replacement have been extensively used in treatment of cervical degenerative disease. Its short-term therapeutic effects are encouraging, but it lacks of long-term and comprehensive evaluation.
OBJECTIVE:To observe the folow-up results of a group of cases of anterior cervical discectomy and Mobi-C intervertebral disc replacement for more than 5 years.
METHODS:A total of 25 cases of cervical spondylosis were treated in the 309 Hospital of Chinese PLA from January to September 2009. 19 of them were folowed up. Al patients received anterior cervical discectomy and Mobi-C intervertebral disc replacement. Twenty-three Mobi-C intervertebral disc prostheses were implanted. The range of motion was measured using lateral X-ray films during extension and flexion. Ectopic ossification was assessed by McAfee method. According to the cervical vertebra MRI images, the degeneration of adjacent segments was determined using Pearce classification. NDI score was used to evaluate the function of cervical spine. Pain improvement was evaluated using visual analogue scale score.
RESULTS AND CONCLUSION: A total of 19 patients were folowed up for 59-65 months, averagely 62 months. No significant difference in range of motion was detected before surgery and during final folow-up (P > 0.05). Ectopic ossification in two cases and the degeneration of adjacent segments in one case were found during final folow-up. No prosthesis loosening or displacement appeared. Visual analogue scale score and NDI score were significantly lower during final folow-up compared with that before surgery (P < 0.05). These results indicate that under the premise of reasonable choice of indications, the therapeutic effect of Mobi-C intervertebral disc replacement for degenerative cervical spondylosis was satisfactory in five-year folow-up. The range of motion was good, and the incidences of ectopic ossification and the degeneration of adjacent segments were low.

OBJECTIVE:To observe the clinical efficacy and ADR of Fuzheng huaji pills in the adjunctive treatment of mid-dle and advanced primary liver cancer. METHODS:122 patients with middle and advanced primary liver cancer who had lost the chance or were unwilling to accept surgery,radiotherapy or chemotherapy were randomly divided into control group (61 cases) and study group(61 cases). The control group received conservative treatment such as hepatoprotecives;the study group was treat-ed with Fuzheng huaji pills 1 pills per time,3 times a day,additionally for 30 days. The tumor volume changes,major clinical symptom scores,quality of life,hemorheology indexes and alpha-fetal protein(AFP),lab index and ADR were compared between 2 groups. RESULTS:After treatment,tumor stable rate of study group was 67.2%,the improvement rate of life quality 27.9%, and AFP(563.35±143.17)pg/L;the scores of liver pain,abdominal distension,loss of appetite and fatigue,and plasma viscosity, whole blood viscosity,erythrocyte sedimentation rate decreased greatly,there were significant differences,compared to control group (P<0.05). One patient in study group suffered from diarrhea,and the symptom was relieved after symptomatic treatment;no obvious ADR was found. CONCLUSIONS:Through stabling tumor, improving major clinical symptom, life quality and hemorheology indexes,Fuzheng huaji pills play a synergistic treatment effect on primary liver cancer.

Objective Cavernous hemangioma of infant was reported as an obscure diagnosis with the different sensitivity to corticosteroid therapy and various natural courses. Therefore, a clinical studies for the biological classification of deep subcutanious vascular lesions might be needed, which was alluded by Mulliken two decades ago. Methods Infants with cavernous hemangiomas accepted normal system corticosteroid therapy during the first 6 months of life before eight-year-follow-up, which continued until the children were 9 to 10 years old. The expression of PCNA and bFGF, and cellular histological characteristics were observed in 12 cases by biopsy. Results There were two major categories of subcutaneous vascular lesions groups: deep capillary hemangiomas, a lesion regressing slowly, and venous malformation, a lesion growing commensurated with the child. They will be also distinguished on the basis of diverse final treatment results, expression of cellular markers, microscopical characteristics, and physical signs. Conclusion The new classification appears to be helpful to make the choice of therapy for infants with "cavernous hemangiomas" , which is proven to be a terminologic confusion.
