Objective:To investigate the effect of galactose lectin 3 (Gal-3) on the pathogenesis of atrial fibrillation.Methods:This study adopts a case-control study method. 55 patients with non valvular atrial fibrillation (atrial fibrillation group) admitted to the First People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from February to July 2019 were selected, and another 55 healthy individuals who underwent physical examination at our hospital during the same period were selected as the control group. Compare the general data and levels of various laboratory indicators between two groups, including blood routine, fasting blood glucose, blood lipids, liver and kidney function, and plasma Gal-3. Analyze the influencing factors of atrial fibrillation and the predictive value of plasma Gal-3 levels for the onset of atrial fibrillation. The measurement data with normal distribution and the measurement data converted to normal distribution after taking natural logarithm are expressed in xˉ± s. The comparison between the two groups is performed by independent sample t test; The measurement data of non normal distribution is represented by [ M ( Q1, Q3)], and Wilcoxon signed rank sum test is used for inter group comparison; The counting data is represented by examples (%), and the comparison between groups is conducted using χ 2 test. The influencing factors of atrial fibrillation were analyzed using logistic regression analysis. Results:The age, NLR, and blood creatinine levels in the atrial fibrillation group were higher than those in the control group [(71.16±9.17) years vs (60.71±10.11) years, (2.32±0.85) vs (1.74±0.81), (74.18±21.61) μmol/L vs (64.69±18.30) μmol/L, t-values are 5.68, 3.66, 2.48, P-values are <0.001, <0.001, 0.015], total cholesterol, HDL-C, LDL-C Albumin and eGFR water were on average lower than those in the control group [(4.31±1.67) mmol/L vs (5.13±0.78) mmol/L, (0.96±0.21) mmol/L vs (1.21±0.32) mmol/L, (2.35±0.65) mmol/L vs (3.04±0.62) mmol/L, (39.58±3.83) g/L vs (44.66±5.61) g/L, (94.84±29.22) mL/(min·1.73 m 2) vs (111.77±21.51) mL/(min·1.73 m 2)] ,The t-values are 3.30, 4.87, 5.69, 5.54, 3.46, and the P-values are 0.001,<0.001,<0.001,<0.001, 0.001, respectively. The plasma Gal-3 levels in the atrial fibrillation group were higher than those in the control group [(12.79±4.24)] μg/L vs (7.31±2.28) μg/L], the difference was statistically significant ( t=8.43, P<0.001), and the plasma Gal-3 level in the persistent atrial fibrillation group was higher than that in the paroxysmal atrial fibrillation group [(14.03±3.95) μg/L vs (11.51±4.21) μg/L], the difference was statistically significant ( t=2.29, P=0.026). The results of multivariate logistic regression analysis showed that after excluding other factors, Gal-3 remained an independent influencing factor for atrial fibrillation (odds ratio=1.66, 95% confidence interval: 1.29-2.12, P<0.001). Conclusions:Plasma Gal-3 is an influencing factor for the onset of atrial fibrillation. After excluding other factors, Gal-3 remains an independent influencing factor for atrial fibrillation, with an increase of 1 μg/L in Gal-3 increases the risk of atrial fibrillation by 1.66 times.

Fibroblast growth factor receptors (FGFRs) have emerged as promising targets for anticancer therapy. In this study, we synthesized and evaluated the biological activity of 66 pyrazolo[3,4-

Objective:To explore whether hyperuricemia was an independent risk factor for all-cause mortality in patients with atrial fibrillation.Methods:Patients with atrial fibrillation who were confirmed by 12-lead electrocardiogram in 11 hospitals of Kailuan Group from 2006 to 2007 were selected as the research objects.All patients were followed up by prospective cohort study, and all-cause deaths were observed.The last follow-up time was December 31, 2013.Kaplan-Meier curve and Cox proportional hazards model were used to analyze and compare the risk of all-cause mortality in patients with atrial fibrillation in the hyperuricemia group compared with the normal uric acid group.Results:A total of 388 community-based patients with atrial fibrillation were included in the final statistical analysis, with 136 all-cause deaths occurred during an average follow-up period of 6.93 years.The incidence of all-cause mortality was 9.24% per year(36/390)in the hyperuricemia group, whereas 5.16% per year(100/1 937) in the normal uric acid group.In the univariate Cox proportional risk model analysis, the risk ratio (95% CI) of all-cause death in patients with atrial fibrillation in the hyperuricemia group (95% CI) was 1.84(1.26-2.69) times that in the normal uric acid group ( P<0.01). After adjusting for potential confounding variables, the adjusted risk ratio (95% CI) of all-cause death in patients with atrial fibrillation in hyperuricemia group was still 1.94(1.32-2.85) times of that in normal uric acid group ( P<0.01). After adjustment for potential confounding variables, for each 0.01 g/L increase in uric acid (1 g/L=5 950 μmol/L), the risk of all-cause death in patients with atrial fibrillation increased by 1.15 (1.05-1.26) times ( P<0.01). Conclusion:Hyperuricemia was an independent risk factor for all-cause death in patients with atrial fibrillation in community.

Objective:Based on the data of Global Burden of Disease 2019 data, to analyze the past, current, and future burden of disability-adjusted life years (DALYs) in China and compare with the international status.Methods:The total number of DALYs, age-standardized DALY rate, and the composition of different subgroups were extracted and described to analyze the time trend in 2000-2019 and the current situation in 2019 for Chinese female breast cancer. The burden of DALYs in 2050 was predicted by Joinpoint using average annual percent change (AAPC).Results:In 2000-2019, the ranking of DALYs caused by female breast cancer in China rose from the fourth to the second in all female cancers. The total DALYs increased by 48.4%, of which the years lived with disability increased from 4.8% to 8.8%. The age-standardized DALY rate only slightly decreased (AAPC=-0.3%; which increased during 2016-2019, AAPC=1.6%). In 2019, the age-standardized DALY rate for breast cancer in China was 278.0/100 000. The DALYs were 2.88 million (accounting for 14.2% of the global burden and 12.1% of all female cancers burden in China), 26.5% of which attributed known risk factors (overweight and obesity were the largest: 0.34 million DALYs, but some common breast cancer risk factors were not available on the platform, such as menstruation and fertility). In 2050, the prediction suggests that the total DALYs caused by female breast cancer in China will reach 3.80 million person-years-5.16 million person-years, increasing 32.1%-79.4% over 2019. From 2000 to 2019, the peak age of DALYs and DALY rate became older, and the DALYs among females aged 65 years and above increased faster than those younger than 65 years (AAPC were 4.8% and 1.3%, respectively). In 2019, females aged 45-74 (the starting age recommended by local guidelines for breast cancer screening) contributed 74.3% of the total DALYs.Conclusions:Over the past 20 years, the age-standardized DALY rate for breast cancer in female populations in China has not changed obviously. Without the continuous expansion of effective intervention and population aging, the burden of DALYs for female breast cancer in China will increase. DALYs for breast cancer attributed leading risk factors were still limited.

Objective:To detect and analyze the contents of eight metal elements in water samples of plague foci in Yunnan Province.Methods:During the period from December 2015 to November 2016, the plague foci of Yulong, Jianchuan and Lianghe were selected as sampling sites, water samples were collected in areas with rodent activities in the 4 seasons of spring, summer, autumn and winter. The contents of eight metal elements calcium (Ca), iron (Fe), zinc (Zn), chromium (Cr), plumbum (Pb), manganese (Mn), cadmium (Cd) and cuprum (Cu) in water samples were measured by flame atomic absorption spectrometry (FAAS), and the data [median (interquartile distance)] were statistically analyzed.Results:Twenty-six, 58 and 54 water samples were collected from Yulong, Jianchuan and Lianghe plague foci, respectively. The contents of metal elements of Pb and Cd in water samples of the three plague foci [Yulong: 0.19 (0.78) and 0.08 (0.07) mg/L; Jianchuan: 0.23 (0.56) and 0.03 (0.06) mg/L; Lianghe: 0.13 (0.61) and 0.09 (0.08) mg/L] were higher than that of "Environmental Quality Standards for Surface Water" (Pb: 0.10 mg/L, Cd: 0.01 mg/L). There were significant differences in the contents of Ca and Cd elements among the three regions ( P < 0.05), but there was no significant difference in the contents of the other 6 metal elements among the three regions ( P > 0.05). The content of Ca element was the highest in Yulong plague foci, and the lowest in Lianghe plague foci ( P < 0.017). In the Yulong plague foci, there was no statistically significant difference in the content of Fe element in different seasons ( P > 0.05), and the differences in the contents of the other 7 metal elements were statistically significant ( P < 0.05). There was no significant difference in the content of Cr element in Jianchuan plague foci in different seasons ( P > 0.05), and the differences in the content of the other 7 metal elements were statistically significant ( P < 0.05). There was no significant difference in the content of Ca element in Lianghe plague foci in different seasons ( P > 0.05), and the differences in the content of the other 7 metal elements were statistically significant ( P < 0.05). Conclusion:The metal element contents of Pb and Cd are relatively abundant in water samples from 3 plague foci of Yunnan Province, and the seasonal variation trend of metal element content in water samples of Yulong and Jianchuan plague foci is similar.

Recently, the 2019 novel coronavirus (2019-nCoV) pneumonia outbroke in Wuhan and rapidly spread to all over China and even the world. Because of the strong infectivity and various clinical symptoms, it has brought certain difficulties to the epidemic prevention and control. Currently there is no specific drug for 2019-nCoV. Previous drugs used to treat other coronaviruses may be effective, but further clinical trials remain needed. We reviewed literature on the epidemiology, etiology, clinical manifestations, imaging manifestations, laboratory examination, diagnosis, complications, treatment and outcome of 2019-nCoV pneumonia.

Objective:To update the disease burden of colorectal cancer (CRC) in Chinese population by integrating the latest multi-source evidences.Methods:Groups of data from GLOBOCAN, series of Chinese Cancer Registry Annual Report (annual report), Cancer Incidence in Five Continents (CI5), Global Burden of Disease Project 2017 (GBD), China Death Cause Surveillance Datasets and China Health Statistical Yearbooks (yearbook) were used to extract the information. Data on incidence, mortality, disability-adjusted life year (DALY) and percentage distribution of sub-location of CRC were used to analyze the latest disease burden in China, and age-standardized rates by world standard population were mainly used. Joinpoint Trend Analysis Software 4.7.0.0 was applied for time trend analysis. Data related to the economic burden of CRC in China were gathered by literature review.Results:(1) Current status: according to the latest annual report, the incidence and mortality rates of CRC were 17.1 per 100 000 and 7.9 per 100 000, respectively among the covered registration sites in 2015. The incidence ratios of male to female and that of urban to rural were 1.5 and 1.4, with the mortality ratios were 1.6 and 1.4, respectively. Similar to data from the annual report, the mortality rate was reported as 6.9 per 100 000 in 2017 by the surveillance data sets. Data from the GBD project showed that, the DALYs caused by CRC in China in 2017 was 4.254 million person years (doubled compared with that of 1990), accounting for 22.4 % of the global burden of CRC. (2) Time trends: according to the annual reports, from 2009 to 2015, the incidence rate and mortality rate of CRC in China decreased by 10.2 % and 9.5 %, respectively. The same trend was also observed in urban sites, but was opposite in rural areas (increased 20.0 % in incidence and 15.2 % in mortality). Results from the Joinpoint analysis showed that the averaged annual percentage change (AAPC) was estimated as -1.6 % ( P<0.05) in the national mortality rate. Similarly, in the incidence and mortality rates of urban sites appeared as AAPC=-1.5 % and -1.4 % (all P<0.05), but inversely in the incidence rate from the rural sites as AAPC=3.3 % ( P<0.05). The yearbook data showed a 9.8 % increase in urban and 20.6 % increase in rural on the mortality in 2017 when compared with 2004, but the Joinpoint analysis showed no statistical significance ( P<0.05). (3) Distribution of sub-location of CRC: the annual report showed that among all the new CRC cases in China in 2015, colon, rectal and anal cancer accounted for 49.6 %, 49.2 % and 1.2 %, respectively, while the proportions were 51.3 %, 47.6 % and 1.1 %, respectively in 2009. The proportion of colon cancer was continuously higher in the urban (>52 %) than that in the rural areas (<44 %). The CI5 Ⅺ data showed that ascending and sigmoid colons were more commonly seen among all the colon cancers. (4) Economic burden: the average annual growth rate of the medical expenditure per CRC patient in China ranged from 6.9 % to 9.2 %, and the 1-year out-of-pocket expenditure of a newly diagnosed patient accounted for about 60 % of their previous-year household income. Conclusions:In China, the overall disease burden of CRC might have been decreased slightly but generally remained stable in the last several years, however, the rising burden appeared in the rural areas should not be ignored. In consistent with findings from a previous review, men and people from the urban areas are considered the target populations for CRC. The finding of higher proportion of colon cancer in urban areas suggests the impact of development of socioeconomic and medical technologies on CRC development and detection. The economic burden of CRC continued to grow.

Objective:To analyze the disease burden of liver cancer in China.Methods:Based on eight data sources, including the series of Chinese Cancer Registry Annual Report, three national death cause surveys in China, China Health Statistical Yearbook, China Death Cause Surveillance Datasets, GLOBOCAN, Cancer Incidence in Five Continents (CI5), WHO Mortality Database and the Global Burden of Disease (GBD), the information on incidence, mortality and disability-adjusted life year (DALY) of liver cancer, were extracted for the analysis on the past, current and future disease burden caused by liver cancer in China.Results:1) Past situation: The long-term data from 1973 to 2012 reported by the CI5 showed that in urban populations in China (taking Shanghai as an example), the incidence rate of liver cancer in males and females decreased by 41.3 % and 36.3 %, respectively, and that in rural areas (taking Qidong as an example) decreased by 32.3 % and 12.2 %, respectively. The Chinese Cancer Registry Annual Reports showed that the national incidence and mortality rates of liver cancer decreased by 8.1 % and 12.8 % respectively from 2005 to 2015. The Joinpoint analysis based on the data from the China Health Statistics Yearbook also showed a declining trend: the average annual percentage change of liver cancer mortality in China from 2002 to 2017 was -3.0 % ( P<0.05), and that in rural areas was -3.1 % ( P<0.05). 2) Current status: GLOBOCAN estimates that the rates of incidence, mortality and prevalence of liver cancer in China in 2018 were 18.3 per 100 000, 17.1 per 100 000 and 10.8 per 100 000, respectively. According to the latest annual report, the incidence and mortality rates of liver cancer in cancer registration areas in 2015 were 17.6 per 100 000 and 15.3 per 100 000, respectively, and both increased with age. The mortality rate was similar to that reported in 2017 (16.7 per 100 000) by the China Death Cause Surveillance Datasets, and the male to female ratio of live cancer deaths was estimated as 3.1. The GBD 2017 reports that the DALYs caused by liver cancer in China reached 11 153.0 thousand in 2017 (accounting for 53.7 % of the global DALYs) and hepatitis B virus infection was always the leading cause. 3) Prediction: The GLOBOCAN 2018 predicts that, by 2040, the number of liver cancer cases and deaths in China would reach 591 000 and 572 000 (with an increase of 50.5 % and 54.9 %, respectively, compared with those in 2018), with a more significant increase in people over 70 years old. 4) Economic burden: According to the literature review of economic burden data on liver cancer, the direct medical expenditure per patient with liver cancer generally showed a rising trend. Conclusions:Multiple data sources indicate that the incidence and mortality rates of liver cancer in populations in China decreased in the past decades, indicating the effect of population interventions. However, the population-level disease burden are still substantial, and comprehensive intervention strategies need to be continually strengthened and optimized, especially the primary and secondary prevention.

Objective:To investigate the acceptance and attitude toward a novel fecal immunochemical test (FIT) in colorectal cancer screening among populations in China.Methods:From May 2018 to May 2019, 2 474 people aged 50-74 years were recruited from five provinces of China (Zhejiang, Anhui, Jiangsu, Hunan and Yunnan). The general demographic characteristics, acceptance of the new FIT technology and operational difficulties through the whole screening process were obtained through questionnaire survey. Multivariate logistic regression model was used to analyze the factors related to difficulties encountered in sampling stool, reading and uploading results.Results:The subjects were (60.0±6.4) years old, and female, high school of above educated, unemployed/retired/other, married and with medical insurance status of “new rural cooperative medical care (NRCMC)” accounted for 61.7% (1 526), 29.0%(718), 34.3% (849), 92.7% (2 293) and 31.3%(775), respectively. The population's acceptance of the FIT technology was 94.8%. In the process of FIT screening, the percentage of occurred difficulties in sampling stool, reading and uploading results were 33.1% (819), 46.4% (1 147) and 62.9% (1 557), respectively. The main difficulties were the uncertainty about whether the sampling operation was standard (28.0%), the inability to accurately judge the result displayed (32.5%) and the need for help without using a smartphone (44.2%). The results of multivariate logistic regression model analysis showed that people aged 65-74 years old and with medical insurance status of “NRCMC” were more likely to encounter difficulties in sampling, and those who were unemployed/retired/other and living with 3 or more family members were less likely to encounter difficulties in sampling. Those aged 65-74 years old, farmers or migrant workers, and those with “NRCMC” were more likely to encounter difficulties in readingresults, and those with 3 or more family members were less likely to encounter difficulties in reading result. Those with “NRCMC” were more likely to encounter difficulties in uploading results, and those with education level of high school or above, living with more than 3 family members were less likely to encounter difficulties in uploading results.Conclusion:The acceptance of the new FIT technology is relatively high among the subjects. Age, education level, occupation, number of family members living together and medical insurance status might be related to difficulties encountered in sampling stool, reading and uploading results, and it can be further strengthened in terms of the technology and characteristics of sub-populations.
