Clinicopathological characteristics and perineural invasion in adenoid cystic carcinoma: a systematic review

IntroductionAdenoid cystic carcinoma is the most frequent malignant tumor of the submandibular gland and the minor salivary glands. It is a malignant neoplasm that, despite its slow growth, shows an unfavorable prognosis.ObjectivesThe aim of this study was to perform a systematic review of the literature on Adenoid cystic carcinoma in the head and neck region and its clinicopathological characteristics, with emphasis on the perineural invasion capacity of the tumor.MethodsA systematic search of articles published between January 2000 and January 2014 was performed in the PubMed/MEDLINE, SciELO, Science Direct, and Scopus databases.ResultsNine articles were selected for this systematic review. These demonstrated that the female gender was more often affected and that malignant tumors showed a high rate of distant metastasis, recurrence, and a low survival rate. The presence of perineural invasion ranged from 29.4% to 62.5% and was associated with local tumor recurrence.ConclusionAdenoid cystic carcinoma is commonly characterized by the presence of pain, high rate of recurrence, metastasis, and a low survival rate. Reporting studies with patient follow-up is of utmost importance for a better clinical-pathological understanding and to improve the prognosis of this pathology.     

微囊化异种甲状旁腺组织移植的研究

目的探讨微囊化异种甲状旁腺(PTG)组织移植对Wistar大鼠甲状旁腺功能低下的治疗作用及微囊的通透性。方法 40只去甲状旁腺Wistar大鼠随机分为微囊组、非微囊组、空囊组、空白对照组。用海藻酸-钡交联微囊包裹兔甲状旁腺组织,移植至Wistar大鼠肾包囊。移植后每隔2周取血测血钙,移植后第16周取移植物进行透射电镜检查及T淋巴细胞、大鼠IgG抗体的免疫组织化学染色。结果微囊组移植后第4周血清钙由(1．62±0．04)mmol／L恢复至正常水平 (2．2～2．6)mmol／L,9例维持至观察期结束(P<0．01),非微囊组、空囊组及空白对照组血清钙差异无统计学意义(P>0．05)。第16周取出移植物检测显示移植物活性良好,微囊周围可见较多T 淋巴细胞浸润,囊壁及囊内IgG抗体染色阳性。结论海藻酸-钡交联微囊可对甲状旁腺组织起到有效的保护作用,使甲状旁腺组织较长时间存活并发挥正常功能。但海藻酸-钡交联微囊并未减轻受体免疫排斥反应的激活且未有效的免疫隔离IgG抗体。     

地方性氟中毒病区胎儿肾上腺皮质细胞超微结构体视学研究

对地方性氟病病区胎儿肾上腺皮质细胞进行超微结构体视学研究。结果显示：病区胎儿肾上腺皮质细胞核比表面和核平均体积缩小，细胞平均截面积和平均体积缩小；线粒体肿胀，平均周长和平均体积增大；粗面内质网体密度缩小。结果表明：机体过量氟对胎儿肾上腺皮质细胞超微结构有损伤作用。     

Effects of Topically Applied Spironolactone on Androgen Stimulated Sebaceous Glands in the Hamster Pinna

The effects of spironolactone (5% SYC-201G, a preparation developed for clinical use in acne vulgaris by Searle Yakuhin K.K.), which is known to have antiandrogenic effects by competitively inhibiting dihydrotestosterone at androgen receptor sites, was topically applied to the androgen stimulated sebaceous glands of adult female golden hamsters. Androgen stimulation, induced by intramuscular injection of testosterone propionate (TP) every other day over a two week period, resulted in a 2.5 to 2.7 time increase in the size of the sebaceous glands of the hamster pinna. Once-daily treatment with 5% SYC-201G or matching placebo was applied to androgen-stimulated hamsters on one pinna only during the same period as TP injection. Comparison between the treated and untreated sides revealed a significant suppression in the sebaceous gland size (p<0.05) by 5% SYC-201G; no such effect was observed with placebo. The difference in the suppression rate of the sebaceous gland size between 5% SYC-201G (23%) and matching placebo (–4.7%) was significant (p<0.01).     

CT导向下经皮射频消融术治疗肾上腺恶性肿瘤

目的对29例肾上腺肿瘤患者行射频消融（RFA）治疗，研究其近期局部治疗效果、不良反应和副作用。方法肾上腺肿瘤患者共29例，病灶总数31个，其中直径≤2．0cm的病灶共5个，2．1-4．0cm者18个，4．1-6．0cm者5个，≥6．1cm者3个，经RFA治疗1个月后行螺旋CT双期增强扫描评价肿瘤治疗效果。结果上述病灶经消融治疗后达到完全坏死者分别为5个、18个、3个、2个。患者无严重并发症出现。结论RFA治疗安全可靠，副作用小，是治疗肾上腺恶性肿瘤的有效方法之一。     

大鼠肾上腺细胞经胶原凝胶三维培养后进行同种移植的实验研究

Objective To investigate a novel method of adrenocotical cells transplantation. Methods Adrenal glands of neonate rats were dissociated into adrenal cortical cells. Cells were cultured in self-made collagen type Ⅰ gel for one week, and then transplanted under the renal capsule of bilateral adrenalectomy mate rats. Blood samples were collected per week after surgery. Animals were sacrificed at the 8th week, and histological characteristics of the allografts, proliferation of transplanted cells, CYP11B1 and CYP11B2 expression as well as plasma aldosterone and corticosterone were observed. Results There were totally 15 rats receiving collagen gel transplantation, and 12 survived 8 weeks post-operation. The plasma cortocosterone level in collagen gel transplantation group was significantly higher than in adrenocortical cell transplantation group, and reached the normal level from 6th to 8th week, but the change in plasma aldosterone level in collagen gel transplantation group was similar to that of adrenocortical cell transplantation group. The adrenocortical cells cultured in gel grew well, and had a high proliferation rate. 95% of them were fasciculata cells which expressed CYP11B1, and the rest were glomerulosa cells which expressed CYP11B2. No inflammatory cell infiltration was observed. Conclusion The proliferation and function of adrenocortical cells could be promoted when they were cultured in collagen gel.
