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.     

甲状旁腺组织中细胞周期素D1过度表达与Rb肿瘤抑制基因的表达和临床意义

目的探讨甲状旁腺组织中细胞周期素D1(cyclin-D1)及视网膜母细胞瘤易感基因(Rb)的表达及临床意义。方法应用免疫组化技术对36例甲状旁腺腺瘤,10例正常甲状旁腺组织及10例甲状旁腺增生中cyclin-D1及Rb肿瘤抑制基因的表达进行检测。结果腺瘤组cyclin-D1的表达明显高于正常组及增生组(P<0.05),正常组同增生组比较差异无显著性(P>0.05)。Rb的表达正常组、增生组和腺瘤组三者之间比较差异均无显著性(P>0.05)。cyclin-D1过度表达和Rb表达与肿瘤大小、血清钙水平及甲状旁腺素(PTH)水平无关。结论cyclin-D1的过度表达在甲状旁腺腺瘤发生中起重要作用。cyclin-D1过度表达导致Rb磷酸化或表达下调而失去细胞抑制效应可能为甲状旁腺腺瘤发生的机制之一。     

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。     

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).

Safety, tolerability and pharmacokinetic study of recombinant human parathyroid hormone in healthy male Chinese subjects

AIM： To determine the safety, tolerability and pharmacokinetic parameters of a new drug recombinant human parathyroid hormone [ rhPTH （1-84）] in healthy male Chinese subjects. METHODS： domly divided Thirty-six healthy male volunteers were rangroups received into 3 groups. The volunteers in these single subcutaneous injection of rhPTH （ 1-84） in a dosage of 1, 2 and 4 μg/kg respectively. Blood samples were obtained before and after administration within 24 hours. The rhPTH concentrations in sennn were determined by enzyme linked immunosorbent assay （ELISA）. The pharmacokinetic parameters determined with use of standard noncompartmental analysis were the maximum serum concentration （ Cmax ）, the time to attain that concentration （ tmax ）, and the area under the serum concentration-time curve up to 24 hours（ AUC0-24 ） and up to infinity （AUC0-∞）. Dose proportionality of pharmacokinetic parameters （AUC, Cmax of every volunteer of each dosage and A UC was computed from log transformed data） and was examined by mean of analysis of variance （ANOVA） using SPSS software package. In the study, subjects＇ symptoms, objective signs, and vital signs, including blood pressure, heart rate, respiratory rate and body temperature, were checked and 12-lead electrocardiography was recorded before and after drug administration within 24 hours. Routine laboratory tests, including hematology, blood biochemistry, serum electrolyte, and urinalysis, were performed before and after drug administration within at 24 hours.[第一段]
