ABSTRACT
Objective@#To observe the effects of axial vascular network flap of scalp or anterolateral thigh perforator flap with fascia lata on repairing defects after radical resection of scalp carcinoma in patients.@*Methods@#From February 2006 to December 2015, twenty-one patients with scalp carcinoma were admitted to our hospital, and the carcinoma invaded external lamina or full-thickness of skull and dura mater. After perfect preoperative examination, carcinoma and scalp tissue in 3 to 5 cm from the edge of carcinoma, external lamina or full-thickness of skull and invaded dura mater were resected and sentinel lymph nodes around carcinoma were cleaned in 3 to 4 days after admission. The postoperative defects with size reached from 11 cm×8 cm to 22 cm×18 cm. The flap transplantation was performed at the same time when quick frozen pathological examination results of resected scalp carcinoma margin tissue, skull, dura mater margin and basal tissue, and sentinel lymph nodes showed completely negative. Defects in 3 elderly patients were repaired by single or multiple axial scalp vascular network flaps, with the resected flaps size ranged from 12 cm×7 cm to 19 cm×14 cm. Defects in the other 18 patients were repaired by anterolateral thigh perforator flaps with fascia lata, with the resected flaps size ranged from 13 cm×10 cm to 23 cm×19 cm and the resected fascia lata size ranged from 8 cm×7 cm to 10 cm×10 cm. The head donor site of flap was repaired by medium thickness skin of head and back; the thigh donor site of flap was repaired by medium thickness skin of thigh on the same side. All patients gave up postoperative radiotherapy, chemotherapy, and other follow-up treatments.@*Results@#After operation, the flap and skin in all patients survived completely, with no vascular crisis or other condition. During the follow-up for 6 months to 9 years, all patients showed good appearance except for baldness in operation area of head, with no obvious malformation in head donor site of flap and skin, no swollen external hernia in the brain tissue, and no local recurrence or distant metastasis of carcinoma. The appearance of thigh donor site of flap and skin was good, with normal muscle strength and movement of lower limbs.@*Conclusions@#Patients with scalp carcinoma were performed with radical resection of carcinoma, and axial vascular network flap of scalp or anterolateral thigh perforator flap with fascia lata were applied to repair the postoperative defects, with good appearance of head operation area and no local recurrence or distant metastasis of carcinoma.
ABSTRACT
Objective To optimize the matrix formula of propranolol hydrochloride gels. Methods On the basis of single factor experiment, central composite design-response surface method was used to optimize the formula. Addition levels of glycerol (A), PEG-400 (B) and HPMC (C) were evaluated as the independent variables.Eight-hour accumulative penetration amount per unit area measured by HPLC was used as the index. Quadratic polynomial was used to estimate the relationship between the index and the independent variables, and to delineate response surface and overlay contour plots in order to select the optimal formulations.Finally, predicted responses were verified. Results The optimized formula consisted of 18.53% glycerol, 8.54% PEG-400 and 2.35% HPMC.The quadratic polynomial regression model of 8-h accumulative penetration amount per unit area:R1=-7 415. 69+306. 10A+167. 47B+4 820. 59C-8. 26A2-9. 81B2-1 025. 75C2 , and the cumulative transmittance was 49.6%. Conclusion A credible model is established by using central composite design-response surface method and the formula of propranolol hydrochloride gels is optimized and the gel is stable and controllable.

ABSTRACT
Objective To investigate the histogenesis,clinicopathological features and biological behavior of goblet cell carcinoid (GCC) of the appendix. Methods 3 cases of GCC of the appendix were studied by light microscopy and immunohistochemistry. Results 3 cases all occured in men. Microscopically: the tumor was composed of goblet cells containing mucin-filled with basal round to crescentic nuclei without atypia.These tumor cells were arranged in single forms,nests or acinus with no central lumen. 1 case was composed of simple goblet cells and typical carcinoid cells were seen in other 2 cases arranged in trabeculae and tubule.There was transition between goblet cells with tubelar and crypt epithelium.Immunohistochemical staining revealed that goblet cells were positively reacted with CgA, Syn, CEA, CK and p53 in 1 case. Conclusions Goblet cell carcinoid of the appendix arise from a pluripotent cell with divergent neuroendocrine and mucinous differentiation .It is a subtype of carcinoids of the appendix.The diagnosis mainly bases on its morphologic changes and immunohistochemical findings. The unpredictable behavior of this tumor is probably related to its component and the degree of infiltration.
