Objective     To compare the short-term efficacy and long-term survival of patients with non-small cell lung cancer (NSCLC) treated by uniportal or three portal thoracoscopic radical resection. Methods     A total of 388 patients who underwent uniportal or three portal thoracoscopic radical resection of lung cancer in the Department of Thoracic Surgery of Anhui Chest Hospital from 2015 to 2016 were analyzed retrospectively. The patients were divided into two groups including an uniportal group and a three portal group according to the procedure. The clinicopathological features, perioperative data and long-term survival of the two groups were compared. Results     Finally, we included 205 patients with 105 males and 100 females at an average age of 58.73±10.93 years. There were 102 patients in the uniportal group and 103 patients in the three portal group. There was no statistical difference in clinicopathological features between the two groups (P>0.05). But compared with the three portal group, the uniportal group had less postoperative drainage, shorter postoperative catheterization time and postoperative hospital stay (P<0.05). There was no statistical difference in the number of lymph node dissection stations between the two groups (P=0.058). The pain score at 24 hours after operation in the uniportal group was significantly lower than that in the three portal group (P<0.001). There was no  statistical difference in the total incidence of complications and the incidence of pulmonary complications between the two groups (P=0.161 and P=0.275). The median survival period and the 1st, 3rd, and 5th year survival rate in the uniportal group was 63.0 months and 95.0%, 75.2%, 51.5%, respectively. The median survival period and the 1st, 3rd, and 5th year survival rate in the three portal group was 61.0 months and 89.3%, 70.9%, 50.5%, respectively. There was no satistical difference in the survival results between the two groups (P=0.440). Conclusion     Uniportal thoracoscopic radical resection of lung cancer is more minimally invasive and safe and effective in the treatment of NSCLC. It can make patients recover faster after operation.

Tripartite motif (TRIM) family proteins are important effectors of innate immunity against viral infections. Here we identified TRIM35 as a regulator of TRAF3 activation. Deficiency in or inhibition of TRIM35 suppressed the production of type I interferon (IFN) in response to viral infection. Trim35-deficient mice were more susceptible to influenza A virus (IAV) infection than were wild-type mice. TRIM35 promoted the RIG-I-mediated signaling by catalyzing Lys63-linked polyubiquitination of TRAF3 and the subsequent formation of a signaling complex with VISA and TBK1. IAV PB2 polymerase countered the innate antiviral immune response by impeding the Lys63-linked polyubiquitination and activation of TRAF3. TRIM35 mediated Lys48-linked polyubiquitination and proteasomal degradation of IAV PB2, thereby antagonizing its suppression of TRAF3 activation. Our in vitro and in vivo findings thus reveal novel roles of TRIM35, through catalyzing Lys63- or Lys48-linked polyubiquitination, in RIG-I antiviral immunity and mechanism of defense against IAV infection.

Objective: To retrospectively analyze the application trend of cohort study in the field of liver cancer in past 27 years and to look forward to the future development trend. Methods: Chinese and English papers reporting the cohort studies of liver cancer conducted in the mainland of China since 1991 were included. The literature management software was used to analyze the publication time, institution, type and objective of the studies and the follow-up performance. Statistical analysis was carried out by using SPSS 21.0. Results: The number and quality of the papers reporting liver cancer-related cohort studies increased significantly in past 27 years and a core English journal group of this field has formed. The average annual growth rates of Chinese and English papers published were 20.4% and 35.2% respectively. About 52.3% of the Chinese papers and 73.5% of the English papers were published in past five years and the quality of these papers was high. The Chinese papers published on Chinese core journals accounted for 49.2%, and the English papers published on SCI periodicals (IF>3) accounted for 47.3%. For the study objective, those published on the domestic journals mainly focused on the pathogenesis of hepatoma (41.5%), studies with large sample size was the common form. The SCI studies mainly focused on the prognosis of liver cancer (40.7%). High-quality SCI papers are more interested in the studies of prognosis, and survival analysis was the common form. Conclusions The application of cohort study in the field of liver cancer gradually increased in China. Large-scale study and prognosis analysis were conducted commonly. However, it is necessary to further improve the researchers’ understanding of cohort study, improve the follow-up quality, and increase the application of scientific evaluation methods, such as survival analysis, for the better solving of clinical problems.

Objective: To describe the 40-years trend for the mortality of colorectal cancer (CRC) in Shanghai and to estimate the effect of age, period, and birth cohort with Age-Period-Cohort (APC) model. Methods: Data on tumor-releated death from 1975 Janurary 1 to 2014 December 31 was derived from the Yangpu District of Shanghai Center for Diseases Prevention and Control tumor registration system. Colonrectal cancer cases (C18.2-C18.9 and C20 in ICD10) were selected for analyses. Crude mortality, age-adjusted mortality, and Average Annual Percent Changes (AAPCs) were calculated for colon cancer and rectal cancer. The difference of AAPCs between male/female and different age groups were tested. An APC model (reference cohort and period were 1900 and 1975, respectively) was constructed to estimate the age-effect, period-effect, and cohort-effect on the colorectal cancer death. Results: During 1975-2014, 6 725 cases died of colorectal cancer (the cased of colon and rectal cancer were 3 684 and 3 041, respectively). The crude mortality and age-adjusted mortality of colon cancer was 8.83/100 000 and 6.76/100 000, respectively. The crude mortality and age-adjusted mortality of rectal cancer were 7.32/100 000 and 5.67/100 000, respectively. For population in Yangpu District, the crude mortality and age-adjusted mortality of colon cancer increased with time, and the crude mortality of rectal cancer increased with time (P<0.001). AAPC of the crude mortality rate (5.6%) and age-adjusted mortality rate (2.3%) of colon cancer were higher than those in rectal cancer (3.0% and -0.3%), respectively (both P values <0.001). AAPC of the crude mortality rate (males vs. females was 6.2% vs. 5.0%, P<0.05) and age-adjusted mortality rate (males vs. females was 2.7% vs. 1.7%, P<0.05) of colon cancer were higher in males than in females. APC model indicted that CRC-related death increased with age. During 1901 to 1941, the RR values of cohort effects for colon and rectal cancer death were 1.09-5.57 and from 1.04-2.28, respectively; During 1946 to 1991, the RR values of cohort effects for colon cancer and rectal cancer were 5.51-4.32 and 2.16-0.89. Conclusion From 1975 to 2014, the mortality of CRC in Yangpu District increased gradually, and colon cancer mortality in males increased faster than that in females. The risk of death from colorectal cancer in the 1946-1991 birth cohort declined.

Hydrological disasters are associated with infectious disease outbreaks and epidemics. Hydrological disasters will lead to water pollution, increased vulnerability to diseases, and increased density of vectors. These factors will facilitate the outbreaks of water-borne/food-borne diseases, vector-borne diseases, and air-borne/contagious diseases. Pre-event preparedness for disasters and post-event reconstruction of both disease surveillance system and water-supply system are key measures to prevent infectious disease outbreaks caused by hydrological disasters. This study reviews the domestic and overseas experiences of controlling infectious diseases after hydrologic disasters, outlines the spectrum of post-disaster infectious disease as well as their epidemiological characteristics, and provides practicable suggestions accordingly.

Objective To explore the application value of monoexponential, biexponential models multiple b values diffusion weighted imaging(DWI) in distinguishing pancreatic cancer from non-tumorous pancreas.Methods Subjects comprised 37 pancreatic cancers confirmed by clinical or surgery.Pancreas multiple b values DWI was performed using 3.0T scanner.Standard apparent diffusion coefficient (ADCstandard) was calculated using monoexponential diffusion model.Pure diffusion coefficient (ADCslow), pseudodiffusion coefficient (ADCfast) and perfusion fraction (f) were calculated using intravoxel incoherent motion(IVIM) diffusion model.Parameters of pancreatic cancers and non-tumorous pancreas were compared using independent samples t test.Results Mean ADCslow value of pancreatic cancer was higher than that of non-tumorous pancreas (0.611×10-3 mm2/s vs 0.521×10-3 mm2/s,P=0.037).Mean ADCfast and f values of pancreatic cancer were lower than that of non-tumorous pancreas (5.066×10-3 mm2/s vs 7.188×10-3 mm2/s,P=0.035;55.8% vs 64.0%,P=0.016;respectively).ADCslow of pancreatic cancer was positively correlated to ADCstandard (r=0.824,P=0.000).ADCfast of pancreatic cancer was negatively correlated to f(r=-0.558,P=0.000).Conclusion ADCslow, ADCfast and f derived from IVIM-DWI model can distinguish pancreatic cancer from non-tumorous pancreas.IVIM-DWI may be a promising and non-invasive tool for early diagnosing and differentiating pancreatic carcinoma from non-tumorous pancreas.

Chronic hepatitis B virus (HBV) infection is a major cause of hepatocellular carcinoma (HCC). In the process from chronic HBV infection to the development of HCC, there is a phenomenon of co-evolution of hepatocytes and HBV. The evolution of hepatocytes includes dedifferentiation and reverse evolution, while the evolution of HBV is mainly "telemorphosis" . Since HBV evolution occurs earlier than the development of HCC, the interaction between them is mainly reflected in the promotion of HCC evolution by HBV mutation. This article briefly summarizes the novel theory termed as cancer evolution and development and elucidates the molecular mechanism of HCC caused by HBV from the perspective of evolution.

Objective: To investigate the clinicopathological features and risk factors in patients with mucinous borderline ovarian tumors (MBOT). Methods: From 1999 to 2006, 66 MBOT patients in our hospital with more than ten-year follow-up were enrolled retrospectively. They were re-classified according to the literature. The clinicopathological features of different subgroups, including age, preoperative serum tumor markers, surgical methods, pathological features, surgical pathology staging, as well as the risk factors of recurrence and survival were analyzed. Results: Median age was 39 years in 66 patients. Before the surgery, 33.3% (20/60) patients had elevated CA125 and 51.7% (30/58) had elevated CA199. The accurate rate for fast frozen pathology of resected specimen was 73.4%. 21 patients underwent conservative surgery and 45 patients underwent extensive surgery. 57 patients underwent comprehensive operation and 43 cases (75.4%) resulted in stage Ⅰ. 48 of the 66 patients (72.7%) had intestinal-type tumors (IMBT) and 18 patients (27.3%) had endocervical-like tumors (EMBT). The median follow-up was 150 months. Eight recurrences (12.1%) were identified. The mean time between surgery to the initial recurrence was 26.4 months (13 to 50 months). Recurrence rate of IMBT was higher than that of EMBT (14.6% versus 5.6%) with no significance (P>0.05). All patients with pseudomyxoma had disease recurrence. Recurrence rate of stage Ⅲ patients was significantly higher than that of stage Ⅰ patients (33.3% versus 9.3%, P<0.05). During the follow-up period, tumor-related death occurred in 2 cases with a 10-year survival rate of 95.4%. Kaplan-Meier method and Log Rank analysis showed that clinical staging and peritonealmyxoma were adverse prognostic factors (P<0.05). Although the recurrence rate of patients undergoing conservative surgery was higher than that of patients with extensive surgery (23.8% versus 6.7%, P=0.047), the overall survival was almost the same between these two groups (P>0.05). Conclusions MBOT patients have relatively good prognosis. IMBT are more common than EMBT subtypes, but recurrence rate and patient survival were almost the same between these two groups. Patients with pseudomyxoma was more likely to have disease recurrence. Patients who underwent conservative surgery resulted in higher recurrence rate but did not affect the overall survival of patient. Pseudomyxoma and clinical staging were adverse prognostic factors in MBOT patients.
