We present a case of subarachnoid hemorrhage induced by chronic suppurative otitis media and discuss the possible mechanism here. Chronic suppurative otitis media is a common suppurative inflammation of middle ear, which can cause sorts of extracranial and intracranial complications in the situation of lower resistance or higher virulence. However, the condition of subarachnoid haemorrhage caused by chronic suppurative otitis media is quite rare. According to this case and previously published articles, we consider that meningitis may be the main reason of subarachnoid hemorrhage induced by chronic suppurative otitis media.

The understanding of the biological behavior of breast cancer has deepened, hence, local treatments for breast cancer have changed from resection to minimally invasive surgery. For patients with early breast cancer, constructing a minimally invasive interven-tion with low systemic toxicity is a problem, especially for cases involving precancerous lesions. Intraductal therapy for breast cancer, which is performed by inserting reagents through breastfeeding openings using suitable carriers, is a promising, accurate, and minimal-ly invasive method for breast cancer prevention and treatment. The combination of intraductal therapy with new therapeutic strate-gies, such as targeted therapy, endocrine therapy, and immunotherapy, might improve the therapeutic effect. Moreover, the mecha-nisms of intraductal therapy for breast cancer incorporate nanotechnology, molecular imaging, and gene sequencing. Intraductal thera-py is based on clinical and pathologic characteristics of Chinese breast cancer patients, and such characteristics must be determined prior to clinical application. This article mainly discusses the research progress of breast intraductal intervention.

Objective: To investigate the relation between ser um hyaluronic acid (HA) concentration and cryopreservation-reperfusion injury. Methods: The animals were randomly assigned to 3 groups: (1 ) group A: the control; (2) group B: liver allografts were stored in lactated R inger's solution (0℃) for 2 h before implantation; (3) group C:liver allografts were stored in lactated Ringer's solution (0℃) for 4 h before implantation. Th e serum sample and liver specimen were taken up at 2 h and 4 h after transplanta tion to detect the concentration of HA, AST and LDH, and to get pathologic obser vation. Results: Serum HA increased earlier and decreased more s hortly than AST and LDH after transplantation in group A. Serum HA increased sig nificantly in group B and C, much higher than that in group A(P<0.01). The i njury of vascular endothelium and the disorder of hepatic sinuses and hepatic lo b ules were observed in group B and C. In the specimen of 4 h in group C, evident infiltration of inflammatory cell was present. Conclusion: Cryopreservation leads to injury of endothelial cell and reperfusion aggravat es this injury. The serum HA concentration indicates the degree of cold ischemia -reperfusion injury.

Objective To study the usefulness of combined flow cytometry (FCM) and polymerasechain reaction examination for clonal TCR gene rearrangements in the diagnosis of T-cell lymphoma (T-NHL). Methods Histopathologic features, immunohistochemistry, flow cytometric immunophenotyping, cytomorphologic evaluation and TCR gene rearrangements of 32 T-NHL were reviewed retrospectively. The control cases were 18 reactive lesions and 1 histiocytic necrotizing lymphaderitis. Results Out of 32 T-NHL,23 were diagnosed as T-NHL by FCM / TCR gene rearrangements. Of 19 control group, 17 were diagnosed as reactive lesions by FCM / TCR gene rearrangements. The sensitivity, specificity and accuracy were 71.9%, 89.5% and 78.4%, respectively. Conclusions FCM / TCR gene rearrangement is a very important technique in diagnosing T-NHL. Thus, patients with fine needle aspiration cytology can be saved from having an invasive surgery.

Background and purpose:Extranodal natural killer/T-cell lymphoma (ENKTL) is a form of non-Hodgkin’s lymphoma. The ENKTL incidence in China is much higher than that in the Western countries. The disease is highly malignant, not sensitive to chemotherapy, has short survival period and poor prognosis. Epstein-Barr virus (EBV) infection has close relationship with the development of the disease. However, there are still a few patients without EBV infection. This study aimed to discuss the clinical features and prognosis of EBV-encoded small RNA (EBER) in situ hybridization negative ENKTL.Methods:From Aug. 2011 to Oct. 2015, 326 cases were diagnosed with ENKTL from the First Affliated Hospital of Zhengzhou University. The expression of EBER was detected by in situ hy-bridization technique. The clinical pathological characteristics and prognosis of EBER-negative patients were analyzed. Results:In 326 patients with ENKTL, the negative rate of EBER was 2.45% (8/326). In 8 EBER-negative patients, the median survival time was 17 months. The log-rank test revealed that there was a signiifcant difference between EBER-negative and EBER-positive curves (χ2=6.407,P=0.011). Multivariate Cox proportional hazards regression analysis showed that in EBER-negative ENKTL, only lactate dehydrogenase (LDH) predicted survival time (P=0.008). EBV-DNA copy number in plasma was not signiifcantly correlated with survival time (P>0.05).Conclusion:The inci-dence of EBER-negative ENKTL is low. Patients with EBER-negative ENKTL have poorer prognosis than EBER-posi-tive patients. Elevated LDH may be a factor indicating poor prognosis.
