Association of IL-12B rs3212227 and IL-6 rs1800795 Polymorphisms with Susceptibility to Cervical Cancer: A Systematic Review and Meta-Analysis

Background: Primary studies have shown that the IL-12B rs3212227 and IL-6 rs1800795 polymorphisms are associated with an increased risk of cervical cancer. However, conflicting results warrant a meta-analysis to obtain more precise estimates. Methods: A comprehensive literate search on PubMed, Web of Science, Scopus, CNKI, and SciELO was performed to collect all eligible studies up to November 10, 2019. The pooled odds ratios (OR) and 95% confidence intervals (CI) were used to calculate the risk. This meta-analysis was carried out by utilizing CMA software. Results: A total of eleven case-control studies including four studies on IL-12B rs3212227 and seven studies on IL-6 rs1800795 were selected. Pooled ORs revealed that the IL-6 rs1800795 polymorphism was significantly associated with an increased risk of cervical cancer (C vs. G: OR = 1.294, 95% CI 1.071-1.564, p= 0.007; CC vs. GG: OR = 1.633, 95% CI 1.059-2.520, p= 0.027; CC+CG vs. GG: OR = 1.312, 95% CI 1.048-1.643, p= 0.018; and CC vs. CG+GG: OR = 1.592, 95% CI 1.268-1.999, p≤0.001), but not IL-12B rs3212227 polymorphism. Stratified analysis by ethnicity revealed that both IL-12B rs3212227 and IL-6 rs1800795 polymorphisms were associated with risk of cervical cancer in Asian women. Conclusions: Our pooled data revealed that the IL-12B rs3212227 and IL-6 rs1800795 polymorphisms may be used to identify individuals at high risk of cervical cancer in Asian women.     

脊柱-骨盆矢状面参数与腰椎椎间盘突出症相关性研究进展

腰椎椎间盘突出症(LDH)是指腰椎椎间盘发生退行性病理改变,纤维环破裂,髓核组织从破裂处突出/脱出,刺激或压迫神经引起的以腰腿痛为主要症状的病变,给患者的工作生活带来一定影响。近年有研究发现,脊柱-骨盆矢状面参数与LDH密切相关,正常脊柱-骨盆形态可使身体处于最佳平衡状态,若发生改变则平衡状态被破坏,导致脊柱矢状面生物力学发生改变,从而加速脊柱退行性变[1-3]。本文查阅分析脊柱-骨盆矢状面参数与LDH的相关性研究,发现脊柱-骨盆矢状面失衡不仅与LDH的发生机制相关,且与其临床症状和预后也有关联,现综述如下。     

Trends in Cervical Cancer Mortality in Brazilian Women who are Screened and Not Screened

Objective: This study aimed to analyze the trend in cervical cancer (ICD C53) mortality in Brazilian regions in women who are who are screened and not screened from 1996 to 2015. Methods: An epidemiological study, of time series of mortality from cervical cancer performed in 90,856 women under 24 years old (343 women), between 25 and 64 years old (32,703 women), and over 65 years old (10,909 women). The data from this research were collected from the DATASUS, from the SIM Health Surveillance Secretariat files, captured through TABNET selecting the resident population by gender and age group and ICD 10 C53 from 1996 to 2015. Results: Among women, 43.8% were white, and 76% had less than eight years of formal education. Polynomial regression showed an increasing trend in cervical cancer mortality in Brazil for women aged 15 - 24 years (p=0.01). Between 25 - 64 and 65 years or older it remained constant, but high (p=0.07; 0.99). The Northeast region pointed a growing trend in women aged 15 to 24 (p=0.01), 25 to 64 years (p=0.01) and 65 or older (p=0.001). The Northeast presented the highest average growth per year. In the Southeast, South and Midwest regions, decreasing trends were observed despite the high rates. The Joinpoint regression showed a 95% confidence interval, and that mortality from cervical cancer in the North region increased throughout the period analyzed. an increasing trend was observed from 1996 to 1998, whereas in the Midwest region, the trend remained stable throughout the period analyzed. The Federal District presented an upward trend from 1996 to 2015. In Brazil, an upward trend was observed throughout the whole period analyzed. Conclusions: Cervical cancer mortality in younger women is becoming more predominant, in addition to the high rate observed for women aged 65 or older.

目的探讨基于运用Pinnacle^39.10计划系统自动计划模块,在不影响肿瘤靶区剂量分布和危机器官(OAR)受量的前提下,最小子野面积参数对宫颈癌自动调强放疗(AP-IMRT)计划的影响。方法收集2018年9月至2019年6月10例宫颈癌患者进行AP-IMRT计划设计,每例患者设计10个AP-IMRT计划,计划靶区(PTV)处方剂量为50Gy/25f,采用7野均分的固定野照射,最小子野面积分别设置为4 cm^2、9 cm^2、14 cm^2、20 cm^2、25 cm^2、40 cm^2、50 cm^2、60 cm^2、80 cm^2和100 cm^2,最小子野数目为70个,最小子野跳数为7MU。采用直接机器参数优化(DMPO)算法评价靶区及OAR剂量分布。结果随着最小子野面积从4 cm^2增大至100 cm^2,AP-IMRT计划的总机器跳数从(649±32)MU降低至(312±26)MU,总子野数目从(69±1)个降低至(28±3)个,分别降低了53%和48%。AP-IMRT计划PTV的均匀性指数(HI)在子野面积4~100 cm^2的范围内呈递增趋势,最小子野面积60~100 cm^2与最小子野面积为4~50 cm^2的HI相比,差异有统计学意义(P<0.05)。PTV的适形指数(CI)在最小子野面积为4 cm^2、9 cm^2和14 cm^2时差异有统计学意义(P<0.05)。不同最小子野面积的AP-IMRT计划间OAR受照射剂量的差异无统计学意义(P>0.05)。结论在使用Pinnacle^39.10计划系统设计宫颈癌AP-IMRT计划时,最小子野面积参数设置在14~50 cm^2的范围内均可满足临床剂量学要求,同时子野数量和机器跳数显著减少。     

Is there an impact of cervical plating on the development of adjacent segment degeneration following Smith-Robinson procedure? A magnetic resonance imaging study of 84 patients with a 24-year follow-up

BACKGROUND CONTEXT

Anterior cervical discectomy and fusion (ACDF) without and with cervical plating (ACDF+CP) are accepted surgical techniques for the treatment of degenerative cervical disc disorders. The effect of CP on the development of adjacent segment degeneration (ASD) remains unclear.
