Objective To summarize our experience on diagnosis and treatment of bilateral primary breast cancer (BPBC). Methods Clinicopathologic records, including clinical manifestations, diagnosis and immunohistochemical expressions of 16 patients with BPBC, treated from 2001 to 2009 in Jiangsu Provincial Cancer Hospital, were analyzed retrospectively. Results The 16 patients with BPBC accounted for 0.47% of all patients diagnosed as malignant tumors of breast during the same period in our hospital. All of the 16 patients were women, with the median age of 53 years (ranged 41-69 years). 7 patients were in bilateral synchronous breast cancer (BSBC), with the median age 47 years (ranged 41-54 years), among whom 5 patients got BSBC just before menopause. 9 patients were in bilateral asynchronous breast cancer (BABC), with the median age 58 years (ranged 43-69 years), among whom 1 patient got BABC before menopause. The median interval between the first and second breast carcinoma of BABC was 52 months (ranged 14-196 months). Conclusions Compared with BABC, the occurrence age of the patients with BSBC was smaller. BABC was more common in premenopausal women. The interval time of BABC was irregular. The active follow-up after the occurrence of contralateral breast cancer and endocrine therapy for estrogen receptor-positive patients were recommended.

objective At present, most operable breast cancers are confirmed by excision biopsy during the operation. If the breast cancer was definitely diagnosed by Fine -Needle Aspiration cytology(FNA) preoperatively, the excision biopsy could be avoid. Methods We diagnosed 118 inpatients of breast mass with physical examination and FNA from September, 1995 to May, 1996. Results The sensitivity and positive predict value of FNA for diagnosing breast cancer are 95.7% and 97.1%. When the palpation and FNA are both positive, the doublepositive predict value for breast cancer is 100% in our study. It is the indication of using FNA that a breast mass was diagnosed as cancer by physical examination. We can treat a breast mass with redical operation directly without excision biopsy, if the breast mass was confirmed as breast cancer by both physical examination and FNA. Conclusion We concluded that the preoperative FNA could partially replace the excision biopsy for confirming breast cancer.

Background There is no effective method to regenerate the optic nerve after injury. It has been recently reported that α-crystallin could promote the survive rate and axon regeneration of retinal ganglion cells (RGCs) effectively. However,the molecular mechanism is not clear. Objective This study was to identify the site of RGCs where the exogenous α-crystallin bind to. Methods RGCs was isolated from retinas of two 2-day-old Long Evans rats and primarily cultured. The positive rate of the RGCs was assessed by counting the number of positive cells for fluorescently-labeled thy1. 1 and cy3 under the fluorescence microscope. The biotinylated exogenous α-crystallin was evaluated by direct coloration and the activity of molecular chaperones was measured by insulin test.After identifying the success of biotinylation along with the activity of molecular chaperones,biotinylated α-crystallin was co-incubated with RGCs and the cells then were reacted to fluorescently labeled avidin for the observation of binding site of exogenous α-crystallin under the laser confocal microscope. Results RGCs of 94% were survived through primary culture. The coloration of biotinylated α-crystallin labeled by the direct coloration method was more intensive, and the value of A450 descended as the decrease of biotinylated α-crystallin concentration,indicating that the α-crystallin was biotinylated successfully. The activity of molecular chaperones of biotinylated α-crystallin was significantly strong but no significant change after being biotinylated after co-incubation of RGCs with biotinylated α-crystallin. Laser confocal microscope examination revealed that co-incubated RGCs with biotinylated α-crystallin showed the red fluorescence on membrane and axon of RGCs rather than cytoplasm and nucleus. The absent response was seen in the control group. Conclusion Exogenous α-crystallin can specifically combine with the membrane of RGCs to play the biological function,but its binding mode and mechanism need further study.
