Objective:To investigate the feasibility of the surgical mode of immediate implant-based breast reconstruction (IIBR) with silicone implants under subcutaneous tissue directly after the total mastectomy in breast cancer.Methods:Data of 53 patients who underwent (skin-sparing mastectomy, SSM) or (nipple-areola-complex-sparing mastectomy, NSM) combined with IIBR in Department of Breast Surgery, Maoming People’s Hospital were retrospectively analyzed. Patients were divided into two groups, 31 cases with the silicone implant placed in different anatomical locations of the chest wall, including subcutaneous tissue, and 22 cases with subpectoral space implantation followed NSM or SSM. The two groups were compared in terms of the short-term and long-term complications, as well as the aesthetic outcome. Within 12 months the local recurrence rate was collected to evaluate the treatment safety of the two groups preserving the thickness of subcutaneous adipose after NSM or SSM.Results:There was no nipple-areola-complex (NAC) or skin flap for both groups, and the time of removing the drainage tube had no significant difference ( P>0.05) . There was no significant difference between the two groups in terms of the short-term complications within 6 months (repeated local infection and unknown effusion occurrence) , the long-term complications after 6 months (local skin with wrinkles sign, prosthesis displacement, and grade III-IV capsular contracture ( P>0.05) . However, the subcutaneous tissue implant group were superior ( P<0.05) in cosmetic outcome because of the breast had better symmetry. What’s more, no local tumor recurrence occurred in either group within 12 months. Conclusions:IIBR of subcutaneous tissue implantation (without patches) is an economical, novel, safe, and effective surgical mode for breast reconstruction, and the key to this operation mode depends on quality control of surgical procedures and the thickness of skin flap ≥ 1cm covering silicone implants. However, due to the cases enrolled in this study is not enough and short follow-up time, further clinical studies are still needed.

Objective To investigate the levels of serum AFP and CEA in healthy physical examination people and their sexual difference.Methods (1 )Healthy physical examination people were divided into the group A(510 males)and group B(477 fe-males);(2)these two groups were subdivided into the group A1 (<40 years old),A2 (40 - <50 years old),A3 (50 - <60 years old),A4(60-<70 years old)and A5 (70 -87 years old),and group B1 (<40 years old),B2(40 -<50 years old),B3 (50 -<60 years old),B4(60-<70 years old)and B5(70-87 years old).The serum AFP and CEA in 987 healthy physical examination peo-ple were measured by the electrochemiluminesence immunoassay,and then the detection results were compared among various groups.Results (1)The detection results of serum AFP and CEA had statistically significant differences between the group A and B (P <0.01);(2)there was no statistical differences among the group A and among the group B.Conclusion The serum AFP and CEA levels in healthy physical examination people in the local area have difference between males and females,which in males are significantly higher than those in females,indicating that the reference range of AFP and CEA should be repectively established ac-cording to different sexes;while the serum AFP and CEA levels have no differences among various age groups in males and fe-males.

The authors have analyzed the present situation of teaching experiment in higher vocational education of china. And then the process of researching and practicing the basic medical experimental technique curriculum reform has been discussed from the aspects such as the teaching aims,curriculum setup,teaching content selection,teaching methods and education evaluation system for the purpose of exploring the experimental teaching mode to fulfill the requirements of the comprehensive career competence of higher vocational education.
