Objective:To investigate the clinical effacies of endoscopic midline and paramedian supracerebellar infratentorial (SCIT) approaches during resection of pineal tumors.Methods:The clinical data of 4 patients with pineal tumors resected via SCIT approach under neuroendoscope in our hospital from December 2017 to March 2019 were analyzed retrospectively. All patients underwent MR imaging plain and enhanced scans before operation. The tumors were resected via SCIT approach under general anesthesia in lateral subduction position (three were via paramedian SCIT approach and one was via midline SCIT approach). The patients were followed up for 3-12 months and the brain MR imaging was reexamined.Results:The tumors were completely resected in 4 patients. Two patients were confirmed to have mixed germ cell tumors, one was confirmed to have seminoma, and the other one was confirmed to have mature teratoma by postoperative pathology. One achieved good recovery after surgery. Two were treated with whole brain and spinal cord radiotherapy, the original lesion in one patient recurred 4 months after resection and systemic chemotherapy was given, and so far, no recurrence was noted; and the other one achieved good recovery. One did not receive chemoradiotherapy due to economic reasons and relapsed 4 months after surgery.Conclusion:It is safe and effective to resect the tumors in pineal region via midline and paramedian SCIT approaches with neuroendoscopy; the best approach should be selected according to the blood supply, size and location of the lesions.

Objective To investigate the correlation between 23 metals and metalloids elements in the urine and thyroid function indicators in the blood of traffic police. Methods A cross-sectional study was performed to assess the effects of 23 metals and metalloids elements in the urine on blood thyroid function indicators in 166 traffic policemen (122 field staff and 44 internal staff) in Wuhan, Hubei Province. Each subject received an occupational health examination. Results After multiple corrections for false detection rates, in the polymetallic model, the levels of urinary manganese and urinary uranium were positively correlated with the levels of thyroid peroxidase antibody (TPOAb) in the blood (β = 66.57, 95% CI 2.92-130.22, P = 0.040 and β = 62.43, 95% CI 14.37-110.49, P = 0.011), and the level of urinary uranium was positively correlated with thyroid stimulating hormone (TSH) levels in the blood (β = 6.20, 95% CI 2.68-9.72 , P = 0.001). Urinary uranium level was negatively correlated with free thyroxine level in the blood (FT4) (β = -2.03, 95 % CI (-3.67 )- (-0.39), P = 0.015), and urinary lead level was negatively correlated with blood TSH level (β = -4.59, 95% CI (-8.67) - (-0.51), P = 0.027). Conclusion Manganese exposure is related to the increase of TPOAb level in blood, uranium exposure is related to the increase of TPOAb and TSH levels and the decrease of FT4 level in blood, and lead exposure is related to the decrease of TSH level in blood, suggesting that more attention should be paid to the effects of heavy metals on the thyroid of traffic police.

Objective To understand the situation of cancer screening of community residents and its association with the knowledge of cancer core knowledge, and to provide reference for the formulation of secondary cancer prevention measures. Methods A cross-sectional survey was conducted among 2 037 residents aged 18-79 who lived in Bao 'an District, Shenzhen. Multivariate Logistic regression analysis was used to investigate the relationship between core knowledge and cancer screening behavior after adjusting for age, gender, education, marriage, occupation and smoking. Results The cancer screening rate of community residents was 28.10%, and the screening rate of middle-aged and elderly people aged 40-79 was 33.50 %.The proportion of “not very well understanding”, “partial understanding” and “basic understanding” of the core knowledge of cancer were 43.91%, 42.33% and 13.76%, respectively, which was higher than that of the non-participants. Multivariate analysis showed that the women, the higher the level of education of college/university or above and the higher the level of knowledge of cancer prevention core knowledge, the higher the probability of participating in cancer screening was OR (95%CI ) : 2.40 (1.86-3.12), 1.65 (1.29-2.10), 1.38 (1.18 - 1.62), respectively. Conclusion The proportion of cancer screening in community residents needs to be improved, and the degree of core knowledge of cancer is closely related to cancer screening behavior. It is suggested to increase the publicity and education of the core knowledge of cancer, and at the same time, carry out the health education of secondary cancer prevention for the key population such as men and people with low education level, so as to improve the proportion of “early detection, early diagnosis and early treatment” of cancer.
