Objective To study the value of sentinel lymph node (SLN) for forecasting axillary lymph node metastasis in breast cancer. Methods Fifty-six patients with breast cancer underwent SLN methylene blue mapping and biopsy,as well as axillary lymph node dissection.All lymph nodes received routine HE staining and immunohistochemical examination. Results SLN was successfully identified in 52 cases (52/56,92.8%).Routine pathological examination demonstrated metastasis of SLN in 22 cases and metastasis of non-SLN in 1 case,the false negative rate being 4 3% (1/23).In the remaining 29 cases without pathologically verified metastasis,immunohistochemical staining showed 1 case of CK-19 (+) with EMA (+) and another 1 case of CK-19 (+) with CEA (+),without metastasis of non-SLN. Conclusions SLN methylene blue mapping and biopsy may forecast axillary lymph node metastasis in breast cancer.

Objective To analyze the clinical pathologic features and prognosis of triple negative breast cancer. Method A total of 570 cases of breast cancer between January 2005 and June 2007 were analyzed,113 cases were negative for estrogen receptor(ER), progesterone receptor(PR) and HER-2 as the triple negative group, 48 cases were negative for ER, PR and positive for HER-2 as the control group. The clinical pathologic features, recurrence and survival of the patients were compared. Results The median age was 46 years old, 15 cases (13.3%) had a breast cancer family history or oophoroma family history,86.7%(98/113) of pathological types were invasive ductal carcinoma,lymph node metastases were detected in 31.0%(35/113 ) in the triple negative group. No significant difference was found for p53 staining between the triple negative group[58.4%(66/113)positive] and the control group [41.7%(20/48) positive] (P>0.05).The median time of follow-up was 24 months,the loss was 5 cases, 10 cases (9.3%, 10/108) had local recurrence and metastasis,and 8 cases (7.4%,8/108) died from breast cancer metastases,2-year survival rate was 96.2% in the triple negative group.There was no significant difference in local recurrence and survival time between the triple negative group and the control group (P>0.05). Conclusions The incidence of triple negative breast cancer is higher than other data reported. Triple negative breast cancer exhibits the same clinical pathological features compared with ER-/PR-/HER-2 + subtypes,and the prognosis is similar to the controls.

OBJECTIVETo evaluate the efficacy and safety of mechanical thrombectomy with the Solitaire AB device in recanalization of patients with acute ischemic stroke of posterior circulation.
METHODSThe clinical data of 17 consecutive patients with acute ischemic stroke of posterior circulation, treated with the Solitaire AB device from August 2011 to August 2015 in Department of Neurosurgery, the Military General Hospital of Beijing People's Liberation Army, were extracted and then retrospectively analyzed. There were 12 male and 5 female patients with a median age of 60 years (ranging from 44 to 75 years). Among them, 8 cases occluded in basilar artery, 4 cases occluded in vertebral artery and 5 cases occluded in vertebral plus basilar artery. Recanalization rate as well as complications after treatment were analysized. Also, neurological functions of the patients before and after treatment, measured by National Institute of Health stroke scale (NIHSS) score, were compared via t test and the clinical outcomes were assessed by modified Rankin score (mRS) at 90 days after treatment.
RESULTSFifteen patients resulted in successfully recanalization, and 2 cases failed both of whose onset to sheath time were above 7.5 hours. The NIHSS score at 7 days was 11±10, which was significantly decreased compared to the admission NIHSS score 17±5 (t=2.949, P=0.009). No symptomatic intracranial hemorrhage case was found after thrombectomy. At 90 days, one patient died(mRS 6), one patient seriously disabled (mRS 5), two patients moderately seriously disabled (mRS 4), four patients resulted in moderate outcome (mRS 3) and the other 9 patients achieved good outcome (mRS 0 to 2). The dead and seriously disabled cases were both due to failure in recanalization. Two moderately seriously disabled cases were probably attributed to their severe admission condition (NIHSS >20) and prolonged time (onset to sheath time >6 hours).
CONCLUSIONMechanical thrombectomy with the Solitaire AB device contributes to a high rate of recanalization with a low probability of complication and improves functional outcome in patients with acute ischemic stroke of posterior circulation.

Intracranial venous sinus thrombosis is a special type of cerebral vascular disease. It usually originates from the later period of wasting disease, brain trauma, puerperium, blood disease, heart disease, eye/nasal/facial infection, meningitis and septicemia. It occurs in different age and sex. Infants, young children, frail elderly people, postpartum women, chronic disease patients are prone to be affected.Because of lacking of typical clinical manifestations, the clinical diagnosis and treatment of this disease is difficult and easily leading to misdiagnosis and mistreatment, which affects the prognosis of the patients.Because of lacking of standardized diagnosis and treatment strategy, different methods are needed. According to the proceeding reports, we reviewed the current progress of the diagnosis and treatment of intracranial venous sinus thrombosis.
