ABSTRACT
Objective@#To analyze the 13 years trend in proportion, risks factors and clinicopathological characteristics of young women with stage Ⅰa2 to Ⅱa2 cervical cancer by using multi-center data of cervical cancer in China.@*Methods@#The clinicopathological data of 46 313 patients with cervical cancer treated from 37 hospitals in China were obtained from January 2004 to December 2016. Using clinical and pathologic data, each patient's stage was reclassified by the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system. A total of 19 041 patients were selected according to the following criteria: FIGO stage Ⅰa2 to Ⅱa2, underwent type B or C radical hysterectomy and pelvic lymphadenectomy. All the patients were divided into two groups: the study group of 1 888 patients aged 35 years or younger and the control group of 17 153 patients aged over 35 years. The 13 years trend in proportion of young women with stage Ⅰa2 to Ⅱa2 cervical cancer, risks factors and clinicopathological characteristics of two groups were retrospectively analyzed.@*Results@#(1) The total number of hospitalized patients with stage Ⅰa2 to Ⅱa2 cervical cancer increased annually. However, a downward trend of patients aged 35 years or younger was observed (P<0.01) . The constituent ratio of patients aged 35 years or younger was significantly greater during 2004—2010 than that during 2011—2016 [12.6% (820/6 484) and 8.5% (1 068/12 557) , respectively; χ2=82.101, P<0.01]. (2) Compared with patients aged over 35 years, patients aged 35 years or younger had an earlier age at menarche, a later age at marriage, lesser gravida and parity (all P<0.01). The positive rate of high-risk HPV infection was not statistically different between two groups (all P>0.05). (3) The proportions of stage Ⅰ, exophytic type and non-squamous histological type in patients aged 35 years or younger were clearly higher than those in patients aged over 35 years (83.4% vs 68.5%, P<0.01; 63.2% vs 56.2%, P<0.01; 13.9% vs 12.0%, P<0.05, respectively). Whereas the poor differentiation ratios of the two groups had no statistical significance (P>0.05). (4) As for the postoperative pathological risk factors, the rate of surgical margin involvement in patients aged 35 years or younger was lower than that aged over 35 years (1.1% vs 1.8%, P<0.05), and the rate of depth of stromal invasion >1/2 in patients aged 35 years or younger was lower than that in patients aged over 35 years (40.1% vs 50.9%, P<0.01). In addition, there were no significant difference in parametrial margin involvement, tumor size and lymph vascular space invasion between two groups (all P>0.05).@*Conclusions@#The trend in proportion among hospitalized patients for stage Ⅰa2 to Ⅱa2 cervical cancer in young women is decreasing yearly. Compared with cervical cancer in middle-aged and elderly women, cervical cancer in young women have an earlier age at menarche, a higher proportion of stage Ⅰ patients and non-squamous histological type.

ABSTRACT
Objective To analyze the core authors, and their organizations, geographical regional distribution of Chinese Journal of Orthopaedics. Methods The core authors, coauthors and their organizations whose articles were published in Chinese Journal of Orthopaedics between 1995 and 2004 were quantitatively analyzed using literature search through CMCI, which programmed by the People's Liberation Army Medical Library and their geographical regions distribution, the organizations of whom had high quantitative publication were determined using literature metrology methods. Results There were 2660 articles published in Chinese Journal of Orthopaedics between 1995 and 2004. All of 1123 authors of 2660 articles had only one article published which accounted for 69.67% of total first authors on the Chinese Journal of Orthopaedics in ten years. There were 2385 articles with one or more coauthors and the cooperative rate was 89.66%, and cooperative degree was 4.11 in the period of time. There were 275 articles with single author, which accounted for 10.34% of total articles. The articles written by the authors from military hospitals, university affiliated hospitals and provinces-level hospitals were 646(24.28%), 1091(41.01%) and 706(26.54%), respectively during the period. There were 218 core authors with 959(36.05%) articles published and there were 20 high-quantities organizations with 1007(37.86%) articles published in this study. The number one region of published articles was Beijing with 667(25.08%) articles. There were 2443 (91.84%) articles pressed from the organizations of affiliated hospitals of universities, provinces-level hospitals and army hospitals. Among them, Tianjin hospital (101 articles), Beijing Jishuitan hospital (100 articles) and affiliated Xijing hospital of the 4th military medical mniversity (79 articles) occupied 10.53% of the pressed papers and they were in the first three positions.
