Zinner syndrome:A case report and review of the literature / 中华男科学杂志

Objective@#To explore the clinical diagnosis and treatment of seminal vesicle cyst (SVC) associated with ipsilateral renal agenesis (Zinner syndrome) in order to promote the understanding of the disease.@*METHODS@#We retrospectively analyzed the clinical data about 1 case ofZinner syndrome diagnosed and treated in our hospital and reviewed the literature related to this disease in domestic and foreign authoritative databases.@*RESULTS@#The patient was a 23-year-old male, diagnosed with Zinner syndrome, treated bytransrectal aspiration of SVC, and discharged from hospital 3 days postoperatively. Follow-upat 6 months after discharge found that the patient no longer felt perineal discomfort in the endstage of urination, but transrectal ultrasonography of the prostate revealedthe samevolume of fluid in the left seminal vesicles as before,which indicated recurrence.@*CONCLUSIONS@#SVC associated with ipsilateral renal agenesis can be considered asZinner syndrome. Transrectal aspiration of SVCcan relieve the local symptoms of the patient but relapse may easilyoccur. Therefore it is not recommended as the first-choice treatment of the disease.

Staging Based Strategies and Practice for Prostate Cancer / 中国中西医结合杂志

Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.

Expression of tumor buds and its relationship with clinicopathological characteristics in endo-metrial carcinoma / 临床与实验病理学杂志

Purpose To investigate the expression of tumor buds and its relationship with clinicopathological characteristics in endome-trial carcinoma. Methods 47 cases of endometrial carcinoma were observed and analyzed by means of clinicopathologic data and im-munohistochemical staining. The connections between tumor buds and clinicopathologic parameters were studied by statistics. Results Of the 47 endometrial carcinoma cases, tumor buds were seen in 18 cases. Tumor buds were correlated with histological grade, lymph node metastases, vascular invasion, Ki-67 index and survival. There were no associations between tumor buds with age, tumor size, pTNM stage or myometrial invasion depth. Immunohistochemistry demonstrated that the level of N-cadherin, vimentin in bud cells was higher than normal carcinoma cells while the level of CK(AE1/AE3),β-catenin and E-cadherin got the opposite results. Conclu-sion Tumor buds may play an important role in the progression of endometrial carcinoma. The immunohistochemical features of bud cells indicated that tumor buds may be a key step in epithelial-mesenchymal transition.
