Key words: human papillomavirus infection; cervical cancer, epidemiology; ChinaThere is strong epidemiologic evidence indicating that human papillomavirus (HPV) plays a central role in the etiology of cervical cancer. [1][2][3][4] The women positive for HPV DNA have a risk of developing cervical cancer 15-50 times higher than those without HPV DNA. 1,2,4,5 Although HPV infection is common among young women, only a small minority go on to develop cervical cancer. This situation was reviewed by a group of researchers, who concluded that viral persistence of oncogenic HPV appears to be crucial for the development of cervical cancer. 6 Indeed, HPV-16, -18, -31 and -33 have been officially declared to be oncogenic by the World Health Organization (WHO). 7 The International Biological Study on Cervical Cancer (IBSCC) study group revealed that on average 92.9% of the tumors contained HPV DNA, with a range of 75-100%. 8 Although this international survey included 10 of the 18 regions of the world and provided the most extensive global view of HPV in cervical cancer, there were no data from China, 1 of the largest populations in the world. Furthermore, there are few published data from a well-designed study using a quality-controlled method on the prevalence of either HPV infection or HPV genotypes in cervical cancers in China.We conducted a multicenter study of HPV infection in cervical cancer by selecting 5 geographic regions of China: Shanghai (Eastern China), Guangzhou (Southern China), Sichuan (Western China), Beijing (Northern China) and Hong Kong (Specific Administration Region). MATERIAL AND METHODS PatientsCervical cancer specimens were collected from each of the 5 regions in China, including Shanghai, Guangzhou, Sichuan, Beijing and Hong Kong. Each of the 5 settings (Tumor Hospital, Shanghai Medical University in Shanghai, Tumor Hospital, Sun Yat-sen University of Medical Sciences in Guangzhou, Second Hospital, West China Medical University in Sichuan, Tumor Hospital, Chinese Academy of Medical Sciences in Beijing, and Prince of Wales Hospital, The Chinese University of Hong Kong in Hong Kong) was responsible for collecting 150 or more tumor specimens consecutively from the year 1997 to 1999. Patients from Hong Kong were prospectively recruited with informed consent, and all specimens were freshly frozen. Those specimens collected in other parts of China were paraffin-embedded and retrieved retrospectively from the pathology files in those reference centers. Ethical approvals were obtained from each of the ethical review boards of the respective institutes. Histology reviewAll histologic slides submitted were reviewed by 1 of the investigators (M.K.M.C.) to reestablish the histologic type and

It is well known that pressure is an important parameter in the SCWO process, because it produces changes in the phase behavior and thermodynamics properties of the system. The influence of pressure on the oxidation efficiency of feeds containing isopropyl alcohol as fuel and acetic acid as waste was studied in an autothermal adiabatic transpiring wall reactor at pilot‐plant scale, at pressures from 13 to 25 Mpa, and temperatures from 600 to 750°C. It was found that reaction temperature decreased between 40 and 100°C, when pressure was lowered, and, subsequently TOC removal decreased. At higher‐temperatures, the decreasing of TOC removal due to pressure difference was reduced. The process was simulated at different pressures using a mathematical model previously developed for the reactor. The Anderko‐Pitzer EoS, especially developed for aqueous systems at high‐temperatures and pressures, was used to have accurate values of the heat capacities of the reaction mixture. It was found that having into account only the effect of pressure in the thermodynamical properties and in the concentration of the reagents, the experimental results could not be explained. Thus, the influence of the pressure in the reaction rate equation had to be considered. Results were qualitatively reproduced considering the reaction rate constant variable with pressure, using a constant volume of activation of −1400 cm3/mol. © 2006 American Institute of Chemical Engineers AIChE J, 2006

Endometriosis is a hormonal disease and also an inflammatory condition. Converging evidence indicates that inflammation and coagulation are 2 major host-defense systems that interact with each other. This study was undertaken to test the hypothesis that women with ovarian endometriomas are in a hypercoagulable state as manifested by the altered procoagulant factors and higher percentage of activated platelets in their peripheral blood. Two sets of participants were recruited. The first set consisted of 50 premenopausal women with endometriosis and 50 age-matched healthy women, and the second set consisted of 21 women with endometriosis and 17 age-comparable women without endometriosis. For the first set, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen, and other coagulation factors, along with their demographic, clinical, and anthropometric data, were measured/retrieved. For the second set, only the percentage of activated platelets in peripheral blood was evaluated. We found that women with endometriosis had a significantly shortened APTT and TT and elevated fibrinogen levels as compared with controls. They also had significantly higher percentage of circulating degranuated platelets, and the percentage was significantly reduced 1 month after surgical removal of endometriotic lesions. These findings provide evidence of a hypercoagulable state in women with endometriosis, reflecting the intimate relationship between coagulation and inflammation. They also suggest that these coagulation parameters such as APTT and fibrinogen and others could potentially be used for diagnostic or prognostic purposes. It also underpins the possibility for the use of antithrombotic therapy in the treatment of endometriosis.

Key Clinical Message Tubal hydatidiform mole is rare and mostly treated with salpingectomy. This manuscript presented a case treated with salpingotomy plus methotrexate that possessed a satisfactory outcome. Our report adds to the experience of using salpingotomy in tubal molar patients.

Background: The aim of this study was to determine the effects of different therapies on patients with cervical cancer (CC) with intermediate risk factors. Methods: Clinicopathological data of 596 patients diagnosed with stage I-IIA CC at the Obstetrics and Gynecology Hospital of Fudan University between January 2013 and November 2015 were retrospectively reviewed. Of the patients, 500 patients received adjuvant therapy including chemotherapy (CT), radiotherapy (RT), and sequential chemotherapy and radiotherapy (CT + RT). Patients who displayed at least one intermediate risk factor number were screened. Results: The median follow-up was 62 months. The 5-year progression-free survival (PFS) and overall survival (OS) of the entire cohort were 90.4% and 90.9%, respectively. Univariate analysis showed that tumor stage, tumor size, pathological type, lymphovascular space invasion, and numbers of medium risk factors were not risk factors for early-stage CC. Compared with the control group, patients who received CT, RT, or CT + RT showed improved PFS and OS (P<0.05). The RT group had lower PFS and OS than the CT and CT + RT groups (P<0.05). Among the 318 patients with a single intermediate risk factor, 297 patients received CT, RT, and CT + RT benefit from adjuvant therapy (P<0.05). Of the 253 patients with high-risk factors, 220 patients received CT, RT and CT + RT get improved PFS and OS (P<0.05).Conclusions: Patients who received adjuvant therapy had better postoperative outcomes than those who did not receive adjuvant therapy. Patients had CT alone or CT combined with RT had better efficacy than those had RT alone.
