This study aimed to explore clinical significance of core needle biopsy (CNB) in pathological diagnosis of breast neoplasm. Seventy one breast neoplasm samples were obtained from Tongzhou Maternal and Child Health Hospital of Beijing between the years of 2006 and 2014. Forty five specimens were obtained via CNB and cases offering 26 of them received neoadjuvant chemotherapy. ⋯ CNB could be used for preoperative diagnosis of breast neoplasm, and help to determine proper treatment regimen, thus elevating the rate of breast conserving. However, this method still has several limitations, particularly in immunohistochemical tests of human epidermal receptor protein-2. Neoadjuvant chemotherapy may influence the accuracy of CNB diagnosis.

The XEN Gel Stent (Allergan Inc., CA, USA) has been widely used in minimally invasive glaucoma surgery to lower intraocular pressure considering reasonable efficacy and safety profiles. However, the XEN gel stent could be occluded by fibrin, blood clots, or the iris due to its small lumen design for preventing postoperative hypotony. To date, only a few studies have assessed XEN occlusion after combined phacoemulsification with XEN gel implantation and how to manage this condition. We describe the first case report of XEN gel stent obstruction by cortical material, demonstrated by anterior segment optical coherence tomography (AS-OCT), which resolved effectively after low-energy neodymium-doped yttrium aluminum garnet (Nd: YAG) laser shock wave treatment. ⋯ To the best of our knowledge, this is the first case report on the efficacy of Nd: YAG laser treatment for recanalization of XEN implant occluded by the cortex. Moreover, AS-OCT could provide additional clinical information for recanalization of the XEN gel stent.

The co-expression of CBX8 and PD-L1 and prognostic value in cervical cancer.
Chromobox homolog 8 (CBX8) plays an important role in the occurrence and development of various tumors, and is closely related to the prognosis of patients with cancer. However, the occurrence, development, and prognostic value of CBX8 in cervical cancer have not been reported yet. In this study, immunohistochemistry was used to detect the expression of CBX8 in cervical cancer tissues and the corresponding normal tissues adjacent to the tumor. ⋯ In addition, CBX8 and PD-L1 co-expression model could better predict the prognosis of patients with cervical cancer, and its area under the receiver operating characteristic curve was similar to that of FIGO stage. CBX8 may be an independent prognostic factor for cervical cancer. Moreover, the CBX8 and PD-L1 co-expression model could predict the postoperative survival of patients with cervical cancer objectively and reliably, which will aid clinicians to shunt patients with cervical cancer based on the risk of death, develop a reasonable treatment plan, and provide personalized prognosis.

Secondary Budd-Chiari syndrome (BCS) occurs due to a blockage in the liver caused by invasion or compression by a large lesion. Conventional treatments for BCS do not solve practical problems, wherease liver transplantation has been only applied as a last-resort therapy and as the only opportunity for a radical cure. We explored the feasibility of applying ex vivo liver resection and autotransplantation (ELRA) for the new indications of treating patients with end-stage hepatic alveolar echinococcosis (HAE). Our center has firstly proposed the idea and successfully treated the 49 patients with HAE. This article for the first time reports the application of ELRA in treating patients with BCS secondary to HAE. ⋯ This article for the first time reports the application of ELRA in treating patients with BCS secondary to HAE, not only provides new ideas for alternative treatments of secondary BCS, but also provides a classification system for secondary BCS. This article describes the technical process of outflow tract reconstruction and the experience for expanding the indications for ELRA. Our study demonstrated that ELRA is well feasible for treatment of BCS secondary to advanced HAE.
