Objective To provide experimental data by exploring the anatomic structure of adult corpus penis vein and lymphatic vessel and the length after releasing penile superficial ligament. Methods The penis length of 16 adult corpuses was measured immediately after releasing the superficial ligament, and make a statistical analysis between the prolonged portion and corpus height. A total of 40 cases of fresh penis specimens were divided averagely into two groups which were performed by vascular casting, indirect-injection of lymphatic vessel, shiff stating and dissection to observe their anatomic structure. Results Prolonged penis length ranged from 2-3 cm. Indian ink of 10% injected from penile glans and frenulum of prepuce mainly flew back through dorsal and lateral lymphatic vessel, but not through ventral vessel. Conclusion Penis can be prolonged about 2-3 cm by releasing the superficial ligament out of erectile condition. One-third proximal lateral area is advised for injection of bulbocavernosus body because blood vessels are less here. Obstinate edema after penis lengthening surgery has a close relation with the damnification of dorsal superficial vein and dorsal and lateral lymphatic vessel of penis.

The development of body donation remains relatively slow in China.One of its main influencing factors restricted to the development of donation is the anatomy teachers' quality.Lots of volunteers to donate and their families are not satisfied with it,which eventually leads to the failure of the donation.Therefore,enhancing anatomy teachers' quality has become one of the key steps in the donated work.It needs to improve the idea awareness of teachers,to standardize the behavior of teachers,to enhance the role models of teachers,and to carry out a regular humanities education and training to truly realize "people-oriented" goals.

Objective To study the feasibility of model building methods by analyzing the advantages and disadvantages between the two different methods to build off-pump coronary artery bypass graft animal model. Methods Twenty dogs were randomly divided into two groups:brachiocephalic artery group and descending aorta group. Small-caliber heterogeneous vascular vessels were used as bridge vessels. The incision was in the fourth intercostal space of the left chest. Vascular anastomosis was firstly done between the brachiocephalic artery and bridge vessels,or between descending aorta and bridge vessels,prior to coronary vascular and bridge vessels anastomosis. Results The dogs of two groups were not dead during operation. Brachiocephalic artery group and the descending aorta group:aortic vascular anastomosis times were (33.9 ±4.8) min and (29.6 ±3.5) min respectively (P<0.05),coronary vascular anastomosis time were (28.5 ±3.0) min and (28. 1 ± 2. 3) min respectively (P>0. 05). The surgical blood losses of the two groups were (77. 5 ± 16. 2) mL and (66. 5 ± 12. 3) mL re-spectively (P>0. 05). After side clamping descending aorta,femoral blood pressure significantly decreased in descending aorta group,and the two dogs had melena after operation. Conclusion Off-pump coronary artery bypass graft models were both constructed successfully by the two ways. Descending aorta group of femoral artery blood pressure violently fluctuated and had abdominal organs’ ischemia reperfusion in-jury. Though brachiocephalic artery group anastomosis group spent a little longer time,they had stable artery blood pressure during operation. As a result,the way of constructing animal model of brachiocephalic artery group is safer.

Objective To establishing an immortal cell line of familial papillary thyroid carcinoma (FPTC), and explore a new approach for studying familial non-medullary thyroid carcinoma (FNMTC). Methods The specimen from a patient with FPTC was selected, separated, and the primary cells were cultured using DMEM/F12 medium (with TSH, T3, EGF and hydrocortisone). To inducing cell immortalization, the exogenous genes SV40T/TERT were transfected into cells by two ways. RT-PCR was used to detect the expressions of thyroid peroxidase (TPO), thyroid globulin (TG), thyroid stimulating hormone receptor (TSHR) and sodium/iodide co-transporter (NIS). Immunofluorescence method was used to detect the expressions of TPO and GPC3. In order to detect the genomic mutations, the peripheral blood DNA of the patient was extracted. The cell genome was detected. Results The FPTC cells adhered to the plate and showed an irregular polygon shape. The cells can stably grow for six months, FPTC-S (with SV40T transfected) passaged to p26, FPTC cells passaged to p23 and FPTC-ST (with SV40T/TERT transfected) passaged to p19. Both FPTC-S and FPTC-ST can stably express TPO, TG and TSHR in mRNA level. MLH1 R217C mutation existed in the peripheral blood of the patient, and BRAF V600E mutation existed in the primary cultured cells. Either the primary or the immortal cells showed MLH1 R217C mutation. Conclusion This study preliminarily established an immortal cell line of familial papillary thyroid carcinoma with MLH 1 R217C and BRAF V600E mutations. This cell line provides a research model for studying these mutations in FPTC.
