Double teeth: evaluation of 10-years of clinical material

The aim of the study was to evaluate 10-years of clinical material referring to the rare dental abnormality of double teeth. The study material consisted of case records, operation-books and radiographic or photographic documentation on patients treated in the Department of Oral Surgery, Silesian Medical University, Katowice, from the 1st of June 2000 to the 31st of May 2010. The following features were considered important: age and sex, the reason why the patient reported for treatment, general state of health, the time of recognition and type of double teeth, location of double teeth, complaints and disturbances connected with double teeth, types of radiographs, the radiographic and macroscopic appearance of double teeth and treatment method. Diagnoses were as follows: eight conrescent teeth, two fused teeth, two geminated teeth and one invaginated tooth. The anomaly of a deciduous tooth was referred to in one case only. Double teeth were most often seen in the region of maxillary incisors and molars but rarely in the mandible. The region of incisors was affected chiefly in children and the region of molars in adults. Double incisors are usually recognized prior to treatment whereas double molars as late as during their extraction. In many cases, neither intraoral radiographs nor pantomographs help to confirm double teeth or provide sufficient information to plan the treatment. In such a situation, CT or CBCT should be used in addition to imaging diagnostics. Double teeth among incisors are usually accompanied by occlusal disorders. Therefore the therapeutic management is conducted by a team, including orthodontists.     

慢性乙型肝炎拉米夫定耐药患者HBV基因型及ALT变化的观察

观察慢性乙型肝炎患者用拉米夫定治疗后HBVP基因变异与不同HBV基因型感染及HBV DNA复升水平和转氨酶变化.收集51例慢性乙型肝炎患者用拉米夫定治疗52-78周后发生YMDD变异的血清标本,对照组128例未用拉米夫定治疗的慢性乙型肝炎患者血清标本,应用聚合酶链反应方法,测定HBV DNA基因型;用限制性片段长度多态性分析方法(PCR RELP)测定HBV DNA YMDD变异;同时进行HBV DNA定量分析.结果显示51例拉米夫定治疗后HBV DNA基因变异患者以B型和C型为主,分别为10例(19.6%)和39例(76.47%),B C混和型2例(3.92%),未见其它基因型.拉米夫定治疗引起HBVDNAYMDD变异可以发生在不同HBV基因型感染的慢性乙型肝炎患者中,与对照组比较二者没有显著性差异.     

Mining immune-related genes with prognostic value in the tumor microenvironment of breast invasive ductal carcinoma

The tumor microenvironment (TME) plays an important role in the development of breast cancer. Due to limitations in experimental conditions, the molecular mechanism of TME in breast cancer has not yet been elucidated. With the development of bioinformatics, the study of TME has become convenient and reliable.Gene expression and clinical feature data were downloaded from The Cancer Genome Atlas database and the Molecular Taxonomy of Breast Cancer International Consortium database. Immune scores and stromal scores were calculated using the Estimation of Stromal and Immune Cells in Malignant Tumor Tissues Using Expression Data algorithm. The interaction of genes was examined with protein-protein interaction and co-expression analysis. The function of genes was analyzed by gene ontology enrichment analysis, Kyoto Encyclopedia of Genes and Genomes analysis and gene set enrichment analysis. The clinical significance of genes was assessed with Kaplan-Meier analysis and univariate/multivariate Cox regression analysis.Our results showed that the immune scores and stromal scores of breast invasive ductal carcinoma (IDC) were significantly lower than those of invasive lobular carcinoma. The immune scores were significantly related to overall survival of breast IDC patients and both the immune and stromal scores were significantly related to clinical features of these patients. According to the level of immune/stromal scores, 179 common differentially expressed genes and 5 hub genes with prognostic value were identified. In addition, the clinical significance of the hub genes was validated with data from the molecular taxonomy of breast cancer international consortium database, and gene set enrichment analysis analysis showed that these hub genes were mainly enriched in signaling pathways of the immune system and breast cancer.We identified five immune-related hub genes with prognostic value in the TME of breast IDC, which may partly determine the prognosis of breast cancer and provide some direction for development of targeted treatments in the future.     

Wip1基因沉默对结肠癌细胞化疗敏感性的影响

目的:观察靶向Wip1基因的特异性siRNA序列对结肠癌细胞Wip1基因的抑制效应,探讨Wip1基因沉默对结肠癌细胞化疗敏感性的影响。方法:将Wip1-811 siRNA转染入Wip1高表达的RKO结肠癌细胞株,采用real-time PCR法检测Wip1 mRNA的表达,采用Western blotting方法检测Wip1蛋白表达,采用MTS方法检测结肠癌细胞活力,流式细胞术检测细胞凋亡及细胞周期。结果:Wip1-811 siRNA明显抑制Wip1的表达。抑制Wip1基因表达后,转染组RKO结肠癌细胞对抗肿瘤药物的敏感性增加,5-氟尿嘧啶处理组RKO结肠癌细胞活力由(89.4±6.6)%降至(74.7±3.9)%(P0.05),奥沙利铂处理组细胞活力由(77.9±2.4)%降至(66.7±2.9)%(P0.05)。转染Wip1-811 siRNA后,5-氟尿嘧啶处理组细胞凋亡比例由(7.7±0.5)%升至(12.3±3.2)%(P0.05);奥沙利铂处理组细胞凋亡比例由(14.7±2.1)%升至(34.0±2.1)%(P0.05)。结论:沉默Wip1基因表达能增强结肠癌细胞的化疗敏感性。

A rare coexistence of primary hyperparathyroidism and hyperthyroidism due to toxic nodular goiter--a case report

The frequent association of thyroid and parathyroid disorders has been reported. Most commonly, hyperthyroidism may coexist with hypercalcemia, but the latter is successfully treated when euthyroidism is achieved. However, the concomitant hyperthyroidism with primary hyperparathyroidism is of a rare occurrence. Moreover, it may frequently go unrecognized. In this paper we report a case of a patient with hypercalcemia due to PTH--secreting parathyroid adenoma associated with hyperthyroidism due to toxic nodular goiter. This case demonstrates the dramatic outcome of those two coexisting disorders. We point out that in patients with primary hyperparathyroidism thyroid function test should always be carried out. A proper, first-line treatment of hyperthyroidism will prevent the deterioration of primary hyperparathyroidism course, and thus surgical parathyroid treatment may safely be introduced.
