Background and purpose:Nipple secretion is one of the frequent symptoms in mammary gland disease.Clinically,about 1% breast cancer patients demonstrate with nipple secretion as initial symptom.It could be used as a screening tool for the patients with nipple secretion but no palpated mass and increase the possibility of early diagnosis for breast cancer.In 1997,our country developed a new technique——breast fiberoptic ductoscopy(FDS). It uses a ?(0.7) millimeter optic scope to insert into the nipple discharge canal orifice,and depends on introscope technology to observe and record the normal or abnormal changes in mammary gland ductus.Its advantages are not only in highly diagnostic sensitivity(above 90%),but also in accurate location of tumor,so it can be used to diagnose early breast cancer and mammary gland ductal diseases.This study evaluated the clinical effect of breast FDS in diagnosis and treatment of abnormal nipple secretion.Methods:1 000 patients had been under examination by FDS.Results:Of the 1 000 cases,there were 33 cases((3.3%)) of early breast cancer;412 cases(41.2%) of papilloma and papillomatosis;and 480 cases(48%) of either ductal ectasia and or chronic inflammation.Duct endoscoptic biopsy was successfully performed on 30 cases,220 cases(55%) with chromic inflammation were cured by perfusion.453 cases were received operation.The accordance rate with pathologic eiagnosis was 90.7%.Conclusions:FDS is a very important and new method to diagnose breast.FDS could be inserted into 5th ducta lumen of breast and significantly increase the positive detection of breast cancer.Because the position and nature of the lesions can be determined accurately by FDS,tt is used as intervening treatment for some intraductal papilloma and chronic inflammatory disease.FDS will be of great influence on early diagnoses and treatment of the breast cancer.

Objective: To investigate a new method for improving the therapeutic effect on malignant glioma. Methods: A new type of killer cells, named GS-LAK, was induced by means of costimulating the peripheral ginsenoside(GS) and interleukin-2 (IL-2). Comparing with control group-LAK cells, cytotoxicity of GS-LAK cells against malignant glioma cells(BT325) was examined with MTI method. Results: It showed that GS-LAK cells exhibited some advantages over LAKcells in proliferation, cytotoxicity, as well as the utilizing of IL-2. Conclusion: The application of GS-LAK cells mightopen a new prospect to clinical therapeutic approach to malignant glioma.

Objective To investigate the effects of human amniotic membrane on the survival of the crossboundary perforator flap in rats through distal subcutaneous implantation.Methods From February,2016 to December,2016,38 SD rats weighing 270-300 g were randomly divided into experimental group and control group (n=19).A three-territory perforator flap (3 cm× 10 cm) with the iliac artery as the pedicel elevated on the right dorsum of the rats.Experiment group,a section of amnion was sutured to the distal subcutaneous of the flap and then the flap was sutured back to its donor site.Control group,after the flap elevated,directly sutured back to its donor site.The blood flow of the pedicel were detected by laser Doppler flowmetry at the day before surgery,1 day after surgery,3 and 7 days after surgery,with 3 rats in every group.When the rats were anesthetized,biopsies were taken from the choke area Ⅱ at the day before surgery,3 and 7 days after surgery,with 9 rats in every group.When the rats were anesthetized,HE was used to compare the diameter size of the artery and vein at the same site.At day 7,measure the survival area of the flap,and 3 of them observe the vessel of the flap by lead oxide-gelatine technique.Results The survival rate of the experimental group and the control group after 7 days were (89.09±4.23)％ and (74.56-±5.59)％ respectively,the experimental group was significantly higher than that of the control group (t=5.48,P=0.00).X-ray showed that 7 days after operation,the pedicel of iliac artery in the experimental group was bigger than that in the control group.The blood flow detection showed that the blood flow of the experimental group was higher than that of the control group (t=2.39,3.06;P=0.03,0.00,respectively) at day 1 and day 3 after surgery.Hematoxylin eosin staining showed that arteriovenous tube diameter at the Choke Ⅱ were gradually increased on the day3 and day7 after surgery in both group,but the experimental group diameter expanded multiple was higher than that of control group (t=3.52,3.50;P=0.02,0.02,respectively).Conclusion Human Amnion subcutaneous embedding may improve the blood flow of the vascular pedicle,expand the microvascular at Choke area Ⅱ,improve microcirculation,as a result to promote the survival of cross perforator flap,while the mechanism is needed to understanding.
