ABSTRACT
Objective@#To investigate the trends in incidence of malignant tumors in Yuyao City, Zhejiang Province from 2011 to 2018, so as to provide insights into formulation of the malignant tumor control strategy.@*Methods@#Data pertaining to the incidence of malignant tumor in Yuyao City from 2011 to 2018 were captured from the Chronic Disease Surveillance Module of Ningbo Municipal Digital Disease Control and Prevention Platform. The crude incidence, Chinese population-standardized incidence, global population-standardized incidence, cumulative incidence (0 to 74 years of age), and truncated age-standardized incidence (35 to 64 years of age) of malignant tumors were estimated, and the trends in incidence of malignant tumors were analyzed in Yuyao City from 2011 to 2018 using average annual percentage change (AAPC).@*Results@#The crude incidence, Chinese population-standardized incidence, global population-standardized incidence, cumulative incidence (0 to 74 years of age), and truncated age-standardized incidence (35 to 64 years of age) of malignant tumors were 433.78/105, 289.37/105, 224.22/105, 25.83% and 83.34/105 in Yuyao City from 2011 to 2018, with AAPC of 5.90%, 3.31%, 3.31%, 2.84% and 4.24%, respectively (all P<0.05), and the incidence of malignant tumors appeared an overall tendency towards a rise. The incidence of malignant tumors increased with age in Yuyao City from 2011 to 2018, and the incidence of malignant tumors was significantly higher in women than in men at ages of 20 to 54 years, while higher incidence was seen in men than in women at ages of 55 years and older. The ten most common malignant tumors included lung cancer, gastric cancer, colorectal cancer, liver cancer, breast cancer, esophageal cancer, thyroid cancer, pancreatic cancer, prostate cancer and cervical cancer, accounting for 78.84% of all malignancies, and the the incidence of lung cancer, colorectal cancer, breast cancer, thyroid cancer, pancreatic cancer and prostate cancer appeared a tendency towards a rise year by year, with AAPC of 8.37%, 5.36%, 6.42%, 24.81%, 5.49% and 18.78%, respectively (all P<0.05). @*Conclusions@#The of malignant tumors appeared a tendency towards a rise in Yuyao City from 2011 to 2018, and lung cancer, thyroid cancer, specific female cancers, male gastrointestinal and prostate cancers should be given a high priority for cancer control in Yuyao City in the future. Early screening and early diagnosis of cancers should be facilitated among high-risk populations.
ABSTRACT
Objective@#To investigate the use of conventional MR imaging to guide treatment in patients with cholecystolithiasis and diffuse inflammatory thickening of gallbladder wall.@*Methods@#The clinical data of patients who were treated in the Ningbo Huamei Hospital, University of the Chinese Academy of Sciences between January 2017 and January 2018 were analyzed. These patients were divided into two groups: patients with acute cholecystitis (n=139) and patients with viral hepatitis combined with cholecystolithiasis (n=67). Differences in the imaging signs in standardized upper abdominal contrast enhanced MRI examinations were retrospectively analyzed.@*Results@#The imaging signs, including stone location, continuity of gallbladder mucosa, exudation in peri-gallbladder space, edema of intrahepatic portal area showed significant differences between the two groups (all P<0.05). On stratification analysis, the type of thickened gallbladder wall, background of liver parenchyma and extent of edema in intrahepatic catchment area also showed significant differences (all P<0.05). The imaging signs, including non-gallbladder neck ductal stones, concentric thickening of gallbladder wall, continuous mucous membrane in gallbladder and no peri-gallbladder space exudation but diffuse edema of intrahepatic catchment area supported the diagnosis of viral hepatitis combined with gallstones. The imaging signs, including discontinuity of gallbladder mucosa, exudation of peri-gallbladder space, diffuse edema of gallbladder wall without a cirrhotic background and edema in intrahepatic portal area supported the diagnosis of acute calculous cholecystitis of gallbladder.@*Conclusions@#Routine upper abdominal contrast enhanced MRI plays an important role in demonstrating the underlying cause of gallbladder wall diffuse edema thickening in patients with gallstones. It provides an important reference for the choice of clinical treatment pathway.

ABSTRACT
Objective To make comparison of consistency between the ESD's informationcalculated values and TLD readout values based on PHILIPS DigitalDiagnost so as to provide reference for realizing information management of medical exposure radiation dose during DR diagnosis and treatment.Methods TLDs were used to obtain the ESD values on chest,abdomen,vertebral body,pelvis and limbs.The exposure parameters were collected from the DICOM files,and the information value of ESD were calculated through the dose area product (DAP) method and the exposure parameter method.The consistency between information value and TLD readout value was compared by intraclass correlation coefficient and the Bland-Altman method.Results The ESD values obtained from DAP method,exposure parameter method and TLD method are,respectively,(0.730 ± 0.870) mGy,(0.720 ± 0.863) mGy and (0.770 ±0.948) mGy.ICC was 0.988 for ESDDAP-TLD and 0.982 for ESDParameters-TLD,respectively.The Bland-Altman map showed that the D-value of ESD obtained from DAP-TLD and Parameters-TLD beyond the 95％ consistency interval was 6.7％.Conclusions The PHILIPS DR daily diagnosis and treatment process is based on fixed-mode programmed diagnosis and treatment.Under the premise of qualified equipment quality control,the information calculated value based on DICOM files has a good consistency with TLD readout value.

ABSTRACT
Objective To develop Chinese version of the Manchester patient safety framework, and evaluate the feasibility of its clinical application. Methods The Manchester patient safety framework (MaPSaF) was transformed into Chinese version by translation and back-translation together with inquiries from experts. The trial study was done firstly among 136 nurses in five pilot wards and followed by five times of focus-oriented group interviews. A semi-structured, in-depth interview was then performed in 12 randomly selected participants and acquired data were analyzed by category analysis. Result Two themes were abstracted: Chinese version of MaPSaF showed a good practicability, effectiveness and operability and it was effective for deepened understanding of patient′s safety culture. Conclusion The Chinese version of MaPSaF can be used for safety culture evaluation during nursing process in China.
