Background Conization is being widely accepted for diagnosis and treatment of cervical intraepithelial neoplasia （CIN）. There is controversy as to which factors are most predictive of a positive cone margin and the clinical significance of it. We conducted this study to identify the predictive factors and to evaluate the clinical significance of a positive cone margin in CIN III patients.Methods A retrospective review was conducted of 207 patients who had undergone conization due to CIN III from January 2003 to December 2005 at Peking Union Medical College Hospital. Of these, 67 had a subsequent hysterectomy Univariate and multivariate analysis were utilized to define the predictive factors for a positive cone margin, and to compare the pathologic results of conization with subsequent hysterectomy.Results One hundred and fifty-one （72.9%） were margin free of CIN I or worse, 37 （17.9%） had CIN lesions close to the margin and 19 （9.2%） had margin involvement. A total of 56 cases （27.1%） had positive cone margins （defined as the presence of CIN at or close to the edge of a cone specimen）. Univariate analysis showed that the parity, cytological grade multi-quadrants of CIN III by punch biopsy, gland involvement, as well as the depth of conization were significant factors correlated with a positive cone margin （P 〈0.05）. However the age, gravidity, grade of dysplasia in punch biopsy, as well as the cone methods were not significantly correlated （P 〉0.05）. Multivariate analysis revealed that the cytological grade （OR=1.92）, depth of conization （OR=2.03）, parity （OR=3.02） and multi-quadrants of CIN III （OR=4.60） were significant predictors with increased risk for positive margin. The frequency of residual CIN I or worse in hysterectomy specimens was found to be 55.6% （20/36） in patients who were margin free, 71.4% （15/21） in patients with CIN occurring close to margin, and 80.0% （8/10） in patients with margin involvement. The frequency of residual CIN III or worse was

mammalian target of rapamycin(m TOR) inhibitor as an attractive drug target with promising antitumor effects has been widely investigated. High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.

2005年是中国承诺碳减排目标的基准年份,因而也是中国城市碳减排战略制定和近中期低碳转型的基准年份和对照年份。中国城市2005年CO_2排放数据的一致性、全面性和精准性对于中国所有城市和每个具体城市的目标考核和评估都有重要意义。基于中国高空间分辨率网格数据(CHRED 2.0)、城市层面统计数据以及大量现场调研和走访,建立2005年中国城市CO_2排放数据集,包括工业能源排放、工业过程排放、农业排放、服务业排放、城镇生活排放、农村生活排放、交通排放7个部门的直接排放数据和间接排放数据。该数据集的建立汇总了86名研究人员的工作成果,在企业、城市不同行业与部门、城市工业和城市总化石能源等不同层面进行了大量的交叉验证和数据分析,有效保障了数据的精确性和准确性。结果显示,2005年中国城市碳排放呈现出较大的体量差异和空间格局差异。排放前10的城市几乎比排放后10的城市的排放量高出两个数量级。高排放城市基本都是城市群的核心城市。东部城市直接排放占全国直接排放比例最高,达到44.59%,其次是西部城市21.76%,中部城市22.70%,东北城市10.95%。
