Objective: To investigate the effects of asperuloside on cervical cancer based on endoplasmic reticulum(ER) stress and mitochondrial pathway. Methods: Different doses(12.5–800 μg/mL) of asperuloside were used to treat cervical cancer cell lines Hela and CaSki to calculate the half maximal inhibitory concentration(IC_(50)) of asperuloside. The cell proliferation was analyzed by clone formation assay. Cell apoptosis, intracellular reactive oxygen species(ROS) and mitochondrial membrane potential were determined by flow cytometry. The protein expressions of cleaved-caspase-3, Bcl-2, Bax, Cyt-c, cleaved-caspase-4 and glucose-regulated protein 78(GRP78) were analyzed by Western blot. And the inhibitor of ER stress, 4-phenyl butyric acid(4-PBA) was used to treat cervical cancer cells to further verify the role of ER stress in the apoptosis of cervical cancer cells induced by asperuloside. Results: Asperuloside of 325, 650, and 1300 μg/mL significantly inhibited the proliferation and promoted apoptosis of Hela and CaSki cells(P<0.01). All doses of asperuloside significantly increased intracellular ROS levels, reduced mitochondrial membrane potential, significantly reduced Bcl-2 protein expression level, and increased Bax, Cyt-c, GRP78 and cleaved-caspase-4 expressions(P<0.01). In addition, 10 mmol/L 4-PBA treatment significantly promoted cell proliferation and reduced apoptosis(P<0.05), and 650 μg/mL asperuloside could reverse 4-PBA-induced increased cell proliferation, decreased apoptosis and cleaved-caspase-3,-4 and GRP78 protein expressions(P<0.05). Conclusion: Our study revealed the role of asperuloside in cervical cancer, suggesting that asperuloside promotes apoptosis of cervical cancer cells through ER stress-mitochondrial pathway.

Gordon Holmes Syndrome is a rare inherited disease characterized by both neurological and reproductive signs and symptoms. Most patients develop neurologic challenges in early adulthood and cerebellar ataxia occurs as the disease progresses. In the majority of patients, hypogonadism is hypogonadotropic but rarely hypergonadotropic. We report a case of a 26-year-old female in Nigeria, with hypergonadotropic hypogonadism and cerebellar atrophy from a non-consanguineous marriage and no family history.

Intracranial arachnoid cysts (AC) are believed to be congenital and chronic subdural hematomas tend to occur in elderly patients with a history of mild head injury. The association between these two entities sporadically occur in relatively young patients but rare in elderly patients. We report a 65-year-old man who presented with headache and dizziness of 2 months’ duration with a history of head injury. Brain computed tomography (CT) a CSDH in right side and a hygroma in left side. After first operation with burr holes in both sides, the patient underwent an early recurrence of acute subdural hematoma in the right side. The evacuation of this hematoma by a craniotomy allowed seeing an AC that we resected partially with complete recovery of the patient. The association CSDH/AC is rare and possible in elderly patients and there is no consensus on treatment.

Background: Occupational dermatitis is considered as the second most common occupational disease. It accounts for 25% of all lost workdays. Several international studies reported a prevalence of occupational dermatitis in healthcare workers between 17% and 55%. This study aims to identify factors that affect the professional outcome of nurses suffering from occupational dermatitis. Methods: This was a multicenter cross-sectional study concerning nurses declared having occupational dermatitis in the central region of Tunisia. A synoptic sheet related to socio-professional and administrative data was completed. A self-administered Questionnaire going over medical and occupational characteristics was completed during a direct interview. Results: The study involved forty nurses working in four public hospitals in the center of Tunisia. Only 37 workers were included in the study. A professional reclassification was introduced among 19 workers (51% of study population). Work-station adaptation was requested in 14 cases (38%). Exposure to allergens in the workplace was eliminated in 20 cases. Two study participants were transferred to other departments (5.4%) and three people retired (8.1%). A statistically significant association was found between professional reclassification and a history of allergic manifestations (p = 0.003). Similarly, a significant association was found between professional reclassification and the allergic agent (p = 0.014). Workstation layout was significantly associated with a history of allergic manifestations (p = 0.039), the palm hand location (p = 0.04), professional eviction (p Conclusion: This study identified the main factors influencing the occupational outcome of nurses suffering from occupational dermatitis. This outcome depended on a history of atopy (especially allergic rhinitis) and sensitization to allergens (thiuram mix).
