Tumor cell proliferation, infiltration, migration, and neovascularization are known causes of treatment resistance in glioblastoma multiforme(GBM). The purpose of this study was to determine the effect of radiation on the growth characteristics of primary human GBM developed in a nude rat. Primary GBM cells grown from explanted GBM tissues were implanted orthotopically in nude rats. Tumor growth was confirmed by magnetic resonance imaging on day 77(baseline) after implantation. The rats underwent irradiation to a dose of 50 Gy delivered subcuratively on day 84 postimplantation(n = 8), or underwent no radiation(n = 8). Brain tissues were obtained on day 112(nonirradiated) or day 133(irradiated). Immunohistochemistry was performed to determine tumor cell proliferation(Ki-67) and to assess the expression of infiltration marker(matrix metalloproteinase-2, MMP-2) and cell migration marker(CD44). Tumor neovascularization was assessed by microvessel density using von-Willebrand factor(vWF) staining. Magnetic resonance imaging showed well-developed, infiltrative tumors in 11 weeks postimplantation. The proportion of Ki-67-positive cells in tumors undergoing radiation was(71 ± 15)% compared with(25 ± 12)% in the nonirradiated group(P = 0.02). The number of MMP-2-positive areas and proportion of CD44-positive cells were also high in tumors receiving radiation, indicating great invasion and infiltration. Microvessel density analysis did not show a significant difference between nonirradiated and irradiated tumors. Taken together, we found that subcurative radiation significantly increased proliferation, invasion, and migration of primary GBM. Our study provides insights into possible mechanisms of treatment resistance following radiation therapy for GBM.

Background and Aim of the Study: HIV/AIDS is best viewed as a major epidemic which poses serious challenges to mankind on a global scale. The aim of this study was to assess the HIV/AIDS-related knowledge among secondary school students in Bangladesh and investigate the association between secondary school students’ socio-demographic characteristics and their level of knowledge about HIV/AIDS. Methods: Following multistage random sampling technique, a total of 384 students aged 11-17 years were sampled from eight secondary schools and interviewed through a predesigned semi-structured questionnaire. Data analysis was done at three stages including descriptive statistics, bivariate analyses, and multivariate logistic regression. Results: The findings of the study revealed that more than half (55.26%) of the students were above 14 years of age and their ages ranged from 11 to 17 years. This study also found that around three-fourths of the students (75.78%) watched television. With regard to knowledge, this study demonstrated that around two-fifths of the students (36.98%) had very good knowledge about HIV/AIDS and their main sources of HIV/AIDS information were television, newspaper, radio, textbooks, and teachers. The bivariate results of the study indicated that students’ age, gender, type of school, household income, fathers’ and mothers’ literacy, and watching television were significantly associated with level of knowledge about HIV/AIDS. In addition, students’ age, mothers’ literacy, and watching television were found as the significant predictors of knowledge about HIV/AIDS. Watching television was documented as the best single predictor. Conclusion: The results of the study strengthen the assumption that there is an influence of students’ socio-demographic characteristics upon their knowledge about HIV/ AIDS. Moreover, this study suggests that more information on HIV/AIDS should be included in the textbooks of secondary school students in Bangladesh to enhance

肝外胆道肿瘤罕见,其中以横纹肌肉瘤最常见。横纹肌肉瘤是一种软组织恶性肌肉骨骼肿瘤,是儿童非常罕见的一种胆总管恶性肿瘤。它通常表现为阻塞性黄疸和/或瘙痒。如果肿瘤没有局部浸润邻近组织,其影像学表现则类似胆总管囊肿。因此,确诊通常是在手术时或术前通过活检。早期诊断、与胆总管囊肿鉴别、尽早开始治疗对延长患者生存时间有重要意义。该文报道1例10岁男童,反复阻塞性黄疸和发热,术前诊断为胆总管囊肿,术后确诊为胆总管胚胎性横纹肌肉瘤。经手术切除、术后化疗,该患儿预后良好。故必须了解这种罕见的肿瘤可以类似先天性胆总管囊肿,并且在儿童阻塞性黄疸的鉴别诊断时应加以考虑。

Objective: To identify the facial nerve trunk (FNT) very easily. quickly and accurately considering the styloid process as the robust anatomically consistent landmark during parotid surgery. Patients and Methods: This prospective study was conducted between January 2010 to December 2022 at a Tertiary care hospital. It included 130 patients: 84 (65%) males and 46 (35%) females with a mean age of 43.52 ± 15.63 years. Patients presented with pleomorphic adenoma (90), chronic sialectasis (05), parotid cyst (03), parotid sinus (01), mucoepidermoid carcinoma (28), adenoid cystic carcinoma (02) and squamous cell carcinoma (01) were subjected to superficial parotidectomy and total parotidectomy. The outcome was evaluated regarding the clinical success of facial nerve function that considered the location of the styloid process in the triangle technique for identification of the FNT during parotid surgery. Results: All 130 patients underwent superficial and total parotidectomy. The facial nerve trunk was successfully identified as the location of the styloid process in the triangle technique in all the patients with no intra-operative complications. Operative time ranged from 50 to 180 minutes with a mean time 90.70 ± 15.68 minutes. Dysfunction of the angle of the mouth due to the deficit of the marginal mandibular nerve (MMN) was noted in 5 patients (3.8%), 02 had difficulty in eye closure (1.5%). No patient reported surgical site infection, skin flap necrosis and hematoma in this series. Conclusion: Styloid process is the prominent robust landmark in the triangle technique for the identification of facial nerve trunk with relative ease, safety and accuracy in the parotid surgical procedure. This can be a very useful method to locate the FNT and minimize facial nerve injury during parotid surgery.
