Objective: To evaluate the feasibility and safety of single-port laparoscopic hysterectomy comparing with multi-port laparoscopic hysterectomy in treatment of benign uterine diseases. Methods: Data were collected retrospectively by review of the medical records of 252 patients who underwent multi-port or single-port laparoscopic surgery for treatment of benign gynecologic diseases. Laparoscopy assisted vaginal hysterectomy (LAVH) was performed for single-port surgery and LAVH and total laparoscopic hysterectomy (TLH) were performed for multi-port surgery. Demographic variables were collected and analyzed by independent t-test and Pearson Chi-Square test. The primary outcome was analyzed by independent t-test and Fisher’s Exact test. Results: A longer operative time was observed in the multi-port surgery group compared with that of the single-port group (p < 0.05). No difference with respect to change of Hemoglobin between the preoperative level and that of the postoperative first day, the number of days from the operation to discharge, uterine weight, and the rate of laparotomy conversion and complications were observed between the two groups. Conclusion: Single-port laparoscopic hysterectomy for treatment of benign uterine diseases is a safe and feasible method.

Splenic hamartoma is a rare benign malformation, composed of an anomalous mixture of normal splenic elements, often found incidentally while working up other complaints or at autopsy. A splenic mass was incidentally found while evaluating the effects of a traffic accident in a 63-year-old woman. Abdominal computed tomography revealed a well-defined splenic mass with rim enhancement. The patient underwent splenectomy. The resected spleen contained a well-defined mass lesion measuring 3.5 cm × 3.0 cm. Microscopic examination revealed disorganized slit-like vascular channels lined by plump endothelial cells without atypia. The cells lining the vascular channels were positive for CD8, CD31, CD34 and vimentin. Endothelial cells that are positive for CD8 are a key feature that differentiates hamartoma from other vascular lesions of the spleen. Although this tumor is very rare, it must be included in the differential diagnosis of splenic mass-forming lesions.

Dear Editor, Telomeres are specific protein-DNA complexes that pro- tect the ends of eukaryotic chromosomes from fusion and degradation and are maintained by a specialized mecha- nism exerted by telomerase and telomere-binding proteins. Mammalian telomeres contain TTAGGG and are associated with a six-protein （e.g. TRF1, TRF2, TIN2, RAP1, POT1, and TPP1） complex called shelterin （de Lange, 2005）, which was involved in telomere homeostasis. Similarly to mammalian telomeres, telomeres in most plants are maintained by tel- omerase and telomere-associated proteins （e.g. AtTBP1, AtTRP1, AtTRB1, POT1, POT2, ku70, and ku80） and consist of tandem arrays of TTTAGGG. Among telomere-associated proteins in Arabidopsis thaliana, AtTRB proteins belong to the SMH （Single-Myb-Histone）-Iike family, in which proteins are composed of an N-terminal Myb domain, a central his- tone Hl-like globular domain, and a C-terminal coiled-coil region.
