Objective To assess true vocal fold (TVF) length and cricothyroid distance(CTD) with ultrasonography in male-to-female (MtF)transsexual voice surgery.Methods Five MtF transsexuals were divided into two groups according to their voice change surgery methods.High-frequency ultrasonography was used to measure the length of true vocal folds and cricothyroid distance.Measurements were compared pre-and post-surgery, and correlations with fundamental frequency (F0) were analyzed.Results The ultrasonography measurements clearly showed the laryngeal structure and TVF measurement marks.After vocal fold shortening and retrodisplacement of anterior commissure(VFSRAC) surgery, the ultrasonographic measurements showed that the shortening length of TVF were 0.37 cm(21%),0.69 cm(37%) and 0.40 cm(25%), respectively.The CTD in ultrasonographicimages were 1.0 cm pre-surgery of cricothyroid approximation (CTA) and-0.33 post-surgery of CTA.The displacement of cricoid cartilage was 1.33 cm, which was consistent with the laryngeal CT image.Conclusion Both TVF length and CTD can be shown by high-frequency ultrasonography, which can be used to quantitatively assessment and follow-up MtF transsexual voice surgery.

Peking University Health Science Center has various characteristics of educational manage-ment practice such as clear three level management, diversified management training and strict quality control, and at the same time there exist many deficiencies, such as lack of the implementation of management regulations and the requirements caused by multi-level management and management quality having ups and downs be-cause of human factors and etc.. By introducing life cycle management into national continuing medical educa-tion project management, we make management run through the whole life cycle of national continuing medical education project, namely five aspects of management from reporting and publishing, planning and publicity, holding and supervision, graduation and certificates, as well as summary and feedback, which plays an impor-tant role in standardizing the national continuing medical education project and improving the quality of the project.

Objective To develop a new method, capillary electrophoresis(CE) based on molecular beacon(MB),for rapid detection of polymerase chain reaction(PCR).To explor the roles of the IL-13 gene exon4 A2044G single nucleiotide polymorphism(SNP) in the pathogenesis of bronchial asthma.Methods The IL-13 exon 4 was amplified by PCR with genomic DNA used as templates from 20 healthy persons and 32 patients with dominantly allergic familial history living in the north of china.Then separating the amplification with capillary electrophoresis followed by hybridization of molecular beacons into the PCR product which were sequenced in the end. Results Detected with CE-MB method,there was significant difference in the distribution of A/G in IL-13exon 2044,A allele frequency was higher in asthma compared with normal controls,same as sequencing. Conclusion The method of capillary electrophoresis based on molecular beacon(MB-CE) is able to be developed as a clinical detecting method for genetic variation diseases.IL-13 A2044G SNP is important in the asthmatic mechanism.

ObjectiveTo investigate the clinicopathological features,immunohistochemical phenotype of pancreatic acinar cell carcinoma.MethodsEight cases of pancreatic acinar cell carcinoma admitted to our hospital from January 2001to January 2011were retrospectively analyzed. The clinicopathological characteristics,and immunohistochemical staining for phenotype were analyzed,then the follow-up data were summarized.ResultsAll 8 patients with pancreatic acinar cell carcinoma was male,with a median age of 47 years old.Tumors were located in the pancreatic head in 4 patients,pancreatic body and tail in 4 patients.The average tumor size was 4.5 cm × 4.0 cm × 3.2 cm,the section appeared as gray or gray-red and presented as solid or cystic lesions.Larger tumors were often accompanied by hemorrhage and necrosis.Microscopically,the tumor cells arranged in acinic,cord,trabecular or solid nests.The cytoplasm was abundant and eosinophilic.The nuclear was round,oval,slightly atypia.lmmunohistochemical staining showed diffusely positive for CAM5.2,α-AT,α-ACT and focally positive for CA19-9,CEA,E-cad,β-cat and MUC-1 and only occasionally positive for AFP,NSE,Syn and CgA.Follow-up data showed there was one case of postoperative death due to postoperative pancreatic leakage with abdominal infection.Liver metastasis occurred in 4 cases,among whom,2 cases died.ConclusionsPancreatic acinar cell carcinoma is a rare epithelial malignant tumor of pancreas,with distinct phenotype characteristics.
