To discuss the effect of varicella vaccination on the clinical characteristics of herpes zoster (shingles) cases aged 20 years and under, and analyze its clinical features. Based on the Yichang Health Big Data Platform, a descriptive study was conducted to collect the information of cases aged 20 years and under in three medical institutions of Yichang Central People's Hospital, Yichang First People's Hospital and Yichang Second People's Hospital from March 2019 to September 2020. According to the history of varicella vaccine, cases were divided into vaccination group and non-vaccination group, and their clinical features and outcomes were compared. The results showed that 46 shingles cases, aged from 7 to 20 years old, were included in this study. 26 males (56.5%), 20 females (43.5%), 15 cases in vaccination group (32.6%) and 31 cases in non-vaccination group (67.4%). 28 cases had thoracic involvement, followed by lumbar (n=8), cranial (n=7) involvements and extremities (n=7). The spread of herpes skin area: 2 cases involved too large area, 21 cases of 10 cm×10 cm, 14 cases of 5 cm×5 cm, 9 cases of 1 cm×1 cm. Herpes number: 26 cases had 10-49 herpes, followed by <10 herpes (n=9), uncountable herpes (n=7) and 50-99 herpes (n=4). The clinical course[M(Q1,Q3)] lasted 20.5 (13.5,24.8) d averagely, 5 cases had postherpetic neuralgia (PHN) and 1 case had respiratory complications. Shingles decrustation time was significantly shorter in vaccination group (Z=-2.01, P<0.05), and there was no significant difference in other characteristics by vaccination. In conclusion, the number and spread of shingles in most children and adolescents are less, and the complications such as PHN are less. Varicella vaccination can reduce the decrustation time and relieve shingles cases with some clinical symptoms.

Background Air pollution is a major public health concern. Air Quality Health Index (AQHI) is a very important air quality risk communication tool. However, AQHI is usually constructed by single-pollutant model, which has obvious disadvantages. Objective To construct an AQHI based on the joint effects of multiple air pollutants (J-AQHI), and to provide a scientific tool for health risk warning and risk communication of air pollution. Methods Data on non-accidental deaths in Yunnan, Guangdong, Hunan, Zhejiang, and Jilin provinces from January 1, 2013 to December 31, 2018 were obtained from the corresponding provincial disease surveillance points systems (DSPS), including date of death, age, gender, and cause of death. Daily meteorological (temperature and relative humidity) and air pollution data (SO2, NO2, CO, PM2.5, PM10, and maximum 8 h O3 concentrations) at the same period were respectively derived from China Meteorological Data Sharing Service System and National Urban Air Quality Real-time Publishing Platform. Lasso regression was first applied to select air pollutants, then a time-stratified case-crossover design was applied. Each case was matched to 3 or 4 control days which were selected on the same days of the week in the same calendar month. Then a distributed lag nonlinear model (DLNM) was used to estimate the exposure-response relationship between selected air pollutants and mortality, which was used to construct the AQHI. Finally, AQHI was classified into four levels according to the air pollutant guidance limit values from World Health Organization Global Air Quality Guidelines (AQG 2021), and the excess risks (ERs) were calculated to compare the AQHI based on single-pollutant model and the J-AQHI based on multi-pollutant model. Results PM2.5, NO2, SO2, and O3 were selected by Lasso regression to establish DLNM model. The ERs for an interquartile range (IQR) increase and 95% confidence intervals (CI) for PM2.5, NO2, SO2 and O3 were 0.71% (0.34%–1.09%), 2.46% (1.78%–3.15%), 1.25% (0.9%–1.6%), and 0.27% (−0.11%–0.65%) respectively. The distribution of J-AQHI was right-skewed, and it was divided into four levels, with ranges of 0-1 for low risk, 2-3 for moderate risk, 4-5 for high health risk, and ≥6 for severe risk, and the corresponding proportions were 11.25%, 64.61%, 19.33%, and 4.81%, respectively. The ER (95%CI) of mortality risk increased by 3.61% (2.93–4.29) for each IQR increase of the multi-pollutant based J-AQHI , while it was 3.39% (2.68–4.11) for the single-pollutant based AQHI . Conclusion The J-AQHI generated by multi-pollutant model demonstrates the actual exposure health risk of air pollution in the population and provides new ideas for further improvement of AQHI calculation methods.

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

Objective: To estimate the risk for type 2 diabetes mellitus (T2DM) death attributed to insufficient whole grain intake in seven regions of China from 2005 to 2018. Methods: Based on China National Nutrition and Health Surveys and China Adult Chronic Disease and Nutrition Surveillance, ordinary Kriging method and locally weighted regression were used to estimate the level of whole grain intake of Chinese residents from 2005 to 2018. Based on the results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 and Chronic Diseases Risk Factors Surveillance in China, we calculated the population attributable fraction (PAF), attributable death number and attributable mortality rate of T2DM due to insufficient whole grain intake in people aged ≥20 years in different regions of China, and we used the 2010 Chinese census data to compare the changes in T2DM deaths attributed to insufficient intake of whole grains in seven regions of China. Results: The whole grain intake levels of Chinese people over 20 years old in 2002, 2010 and 2015 were 19.0 g/d, 14.3 g/d and 19.8 g/d, respectively. The estimated overall whole grain intake level was 20.1 g/d in Chinese residents in 2018, and the intake level was 19.4 g/d in men and 20.8 g/d in women. Among the seven regions, the intake level was highest in northern China (47.4 g/d) and lowest in southwestern China (6.0 g/d). In 2018, the PAF was lowest in northern China (12.8%) and highest in southwestern China (19.3%). From 2005 to 2018, the PAF varied in the seven regions, and the PAF in northeastern China fluctuated around 18.5%. Other regions showed downward trends, especially in northern China and northwestern China, decreased by 26.4% and 21.2%, respectively. Over the past 14 years, the number of attributable deaths in the seven regions showed upward trends, with the highest annual average growth rate of 6.7% in southern China and the lowest annual average growth rate of 2.4% in northern China. In 2018, the standardized T2DM mortality rate attributed to insufficient whole grain intake in China was 3.13/100 000, and the attributable mortality was 3.21/100 000 in men and 3.05/100 000 in women. The standardized attributable mortality rate was highest in southwestern China (3.97/100 000) and lowest in northern China (1.78/100 000). From 2005 to 2018, the standardized attributable mortality rate increased by 11.5% in men and decreased by 8.1% in women. The standardized attributable mortality rate in southwestern, southern and central China increased by 23.7%, 21.3% and 4.2%, respectively. The standardized attributable mortality rate in northern, northwestern, eastern and northeastern China decreased by 20.9%, 11.0%, 4.5% and 3.9%, respectively. Conclusion: The whole grain intake level of Chinese residents was low, and the whole grain intake of residents in all seven regions should be increased, especially in the southwest, and men should have more whole grain intake than women to reduce the death risk in patients with T2DM.

BACKGROUND@#Epilepsy accounts for a significant portion of the global disease burden. However, little is known about the disease burden of epilepsy in China and its provinces.@*METHODS@#We assessed the burden of epilepsy in China and its provinces, municipalities, and autonomous regions from 1990 to 2019. Burden was measured as incidence, prevalence, deaths, years lived with disability, years of life lost, and disability-adjusted life years (DALYs), by age, sex, year, and province. We used the Socio-Demographic Index (SDI) to determine the association between the provincial development level and age-standardized DALY rates of epilepsy from 1990 to 2019.@*RESULTS@#In 2019, epilepsy caused 1367.51 thousand (95% uncertainty interval [UI]: 979.92-1837.61 thousand) DALYs, and the age-standardized DALY rate was 99.77 (95% UI: 71.33-133.52)/100,000. The age-standardized incidence and prevalence rates for epilepsy in China were 24.65/100,000 and 219.69/100,000, increased by 45.00% (95% UI: 8.03-98.74%) and 35.72% (95% UI: 0.47-86.19%) compared with that in 1990, respectively. From 1990 to 2019, the proportion of DALY caused by epilepsy in the age group under 25 years steadily decreased. The proportion of DALYs caused by epilepsy in people aged 50 years and over increased from 9.45% and 10.22% in 1990 to 29.01% and 32.72% for male and female individuals in 2019, respectively. The highest age-standardized mortality rates were seen in Tibet (4.26 [95% UI: 1.43-5.66]/100,000), Qinghai (1.80 [95% UI: 1.15-2.36]/100,000), and Yunnan (1.30 [95% UI: 0.88-1.62]/100,000), and the lowest mortality rates were in Guangdong (0.48 [95% UI: 0.39-0.64]/100,000), Zhejiang (0.56 [95% UI: 0.44-0.70]/100,000), and Shanghai (0.57 [95% UI: 0.41-0.73]/100,000). The age-standardized DALY rates across the country and in provinces, municipalities, and autonomous regions generally decreased as their SDI increased.@*CONCLUSIONS@#The disease burden of epilepsy is still heavy in China, especially in the western provinces. The incidence and prevalence of epilepsy increased between 1990 and 2019, and the burden of epilepsy in the elderly increases gradually. This study provides evidence on epilepsy prevention and care of different regions in China.

In vitro studies have established the prevalent theory that the mitochondrial kinase PINK1 protects neurodegeneration by removing damaged mitochondria in Parkinson's disease (PD). However, difficulty in detecting endogenous PINK1 protein in rodent brains and cell lines has prevented the rigorous investigation of the in vivo role of PINK1. Here we report that PINK1 kinase form is selectively expressed in the human and monkey brains. CRISPR/Cas9-mediated deficiency of PINK1 causes similar neurodegeneration in the brains of fetal and adult monkeys as well as cultured monkey neurons without affecting mitochondrial protein expression and morphology. Importantly, PINK1 mutations in the primate brain and human cells reduce protein phosphorylation that is important for neuronal function and survival. Our findings suggest that PINK1 kinase activity rather than its mitochondrial function is essential for the neuronal survival in the primate brains and that its kinase dysfunction could be involved in the pathogenesis of PD.

Objective:To explore the risk factors of seroma after laparoscopic totally extraperitoneal hernia repair.Methods:The clinical data of 236 patients underwent laparoscopic totally extraperitoneal hernia repair from July 2018 to June 2021 in Jiaozhou Central Hospital of Qingdao City were retrospectively analyzed. The related risk factors of seroma after laparoscopic totally extraperitoneal hernia repair were analyzed.Results:Among 236 patients, the seroma occurred in 36 cases (seroma group), the incidence of seroma was 15.25%; no seroma occurred in 200 cases (non-seroma group). There were statistical differences in the duration of disease ≥5 years, scrotal hernia, internal inguinal ring defect ≥3 cm, rupture of hernia sac, experience of operators <5 years between 2 groups ( P<0.01 or <0.05); there were no statistical difference in age, body mass, type of patch, preoperative complications (including diabetes, chronic obstructive pulmonary disease and cardiac cerebrovascular disease) and operative time between 2 groups ( P>0.05). Multivariate Logistic regression analysis result showed that the duration of disease ≥5 years, scrotal hernia, rupture of hernia sac and experience of operators<5 years were independent influencing factors of seroma after laparoscopic totally extraperitoneal hernia repair ( OR = 5.147, 5.006, 0.044 and 3.315; 95% CI 1.513 to 17.516, 1.845 to 13.583, 0.008 to 0.240 and 1.029 to 10.679; P<0.01 or<0.05). Conclusions:The duration of disease ≥5 years, scrotal hernia, rupture of hernia sac and experience of operators<5 years are independent influencing factors of seroma after laparoscopic totally extraperitoneal hernia repair, and preoperative assessment of risk factors is helpful to reduce the incidence of seroma.

Objective: To analyze mortality and its trend of chronic respiratory diseases (CRD) in China from 1990 to 2019. Methods: Based on the provincial results of China from the 2019 Global Burden of Disease (GBD) study, the average annual percent change (AAPC) of standardized mortality rates of different CRDs were analyzed by using Joinpoint 4.8.0.1, and the age-standardized mortality rate of CRD was calculated by using the GBD 2019 world standard population. Based on the comparative risk assessment theory of GBD, the attributable deaths due to 12 CRD risk factors were estimated, including smoking, indoor air pollution, occupational gas exposure, particulates and smog exposure, environmental particulate pollution, low temperature, passive smoking, ozone pollution, occupational exposure to silica, occupational asthma, high body mass index, high temperature and occupational exposure to asbestos. Results: From 1990 to 2019, the number of deaths and standardized mortality of chronic obstructive pulmonary disease (COPD) showed a downward trend (P<0.001). The number of COPD deaths decreased from 1 244 000 (912 000 - 1 395 000) in 1990 to 1 037 000 (889 000 - 1 266 000) in 2019. AAPC=-0.9% (95%CI: -1.5% - -0.3%), P<0.001; The standardized mortality rate decreased from 217.9/100 000 (163.3/100 000 - 242.0/100 000) in 1990 to 65.2/100 000 (55.5/100 000 - 80.1/100 000) in 2019. AAPC= -4.2% (95%CI:-5.2% - -3.2%), P<0.001. The number of deaths from asthma decreased from 40 000 (30 000 - 58 000) in 1990 to 25 000 (20 000 - 31 000) in 2019. AAPC=-2.0% (95%CI: -2.6% - -1.4%), P<0.001; The standardized mortality rate of asthma decreased from 6.4/100 000 (4.7/100 000 - 9.5/100 000) in 1990 to 1.5/100 000 (1.2/100 000 - 1.9/100 000) in 2019. AAPC=-5.1% (95%CI: -5.8% - -4.4%), P<0.001. The number of pneumoconiosis deaths decreased from 11 000 (8 000 - 14 000) in 1990 to 10 000 (8 000 - 14 000) in 2019, AAPC=-0.2%(95%CI:-0.4% - 0.1%), P=0.200; The standardized mortality rate of pneumoconiosis decreased from 1.4/100 000 (1.0/100 000 - 1.7/100 000) in 1990 to 0.5/100 000 (0.4/100 000 - 0.7/100 000) in 2019. AAPC=-3.1% (95%CI: -3.4% - -2.8%), P<0.001. The number of deaths from pulmonary interstitial diseases and pulmonary sarcoidosis increased from 3 000 (3 000 - 6 000) in 1990 to 8 000 (6 000 - 10 000) in 2019, AAPC=3.5% (95%CI: 2.7% - 4.2%), P<0.001; The corresponding standardized mortality rate changed little from 1990 to 2019, and AAPC was not statistically significant.The age-standardized mortality rates of different CRDs were higher in men than those in women. In 1990 and 2019, the mortality rates of COPD, asthma, pneumoconiosis and interstitial pulmonary disease and pulmonary sarcoidosis increased with age. In 2019, the population attributable fractions (PAFs) for smoking, environmental particulate pollution, occupational gas exposure, particulate and smog exposure, low temperature exposure and passive smoking were 71.1% (68.0% - 74.3%), 24.7% (20.1% - 30.0%), 19.3% (13.0% - 25.4%), 15.7% (13.6% - 18.3%) and 8.8% (4.5% - 13.1%) respectively in men, and the PAFs for environmental particulate pollution, smoking, low temperature exposure, occupational gas exposure, particulate and smog exposure, and passive smoking were 24.1% (19.6% - 29.3%), 21.9% (18.7% - 25.2%), 16.4% (14.0% - 19.2%), 15.6% (10.2% - 21.1%) and 14.7% (7.9% - 21.3%) respectively in women. Conclusions: During 1990-2019, the overall death level of CRD decreased significantly in China, but it is still at high level in the world. Active prevention and control measures should be taken to reduce the death level caused by CRD.

Objective:To analyze the death rate of asthma among Chinese people aged 0-19 years in 2018 and the trend of asthma mortality between 2008 and 2018, in order to guide the research of asthma control management and prevention strategy, and reduce the mortality of childhood asthma in China.Methods:Data from the national disease surveillance points system (DSPs) was adopted.The mortality rates of 0-19-year-old people in different age groups, genders, places of residence and geographical regions from 2008 to 2018 were calculated, and the national death toll of asthma was estimated as well.The annual percentage change (APC) and average annual percentage change (AAPC) were calculated, and the death rate of asthma among Chinese people aged 0-19 years in 2018 and change trend of asthma mortality from 2008 to 2018 were analyzed.Results:In 2018, there was no significant gender diffe-rence in asthma mortality among Chinese people aged 0-19 years among different age groups, places of residence and geographical regions(all P>0.05). From 2008 to 2018, the mortality rate of people aged 0-19 fluctuated from 0.023/100 000 to 0.046/100 000, the highest mortality rate was in 2009 and 2012, and the lowest was in 2018. It was estimated that the total number of deaths among people aged 0-19 years reached the highest in 2009 (148 cases) and the lowest in 2018 (70 cases). It is estimated that the total number of deaths among people aged 0-19 years in China from 2008 to 2018 was 1 158 cases.From 2008 to 2018, the total mortality rate of asthma in Chinese population aged 0-19 years decreased significantly (AAPC=-7.6%, 95% CI: -10.4%--4.7%). There was a significant decrease in male group(AAPC=-7.4%, 95% CI: -12.5%--2.0%), female group(AAPC=-7.5%, 95% CI: -12.7%--2.0%), 1-<5 years old group(AAPC=-11.4%, 95% CI: -17.9%--4.5%), 15-19 years old group(AAPC=-14.4%, 95% CI: -24.8%--2.6%), rural group(AAPC=-9.0%, 95% CI: -13.1%--4.8%) and central areas(AAPC=-13.1%, 95% CI: -24.0%--0.5%), with statistical significance(all P<0.05). Conclusions:The total mortality of asthma in 0-19-year old population decreased significantly from 2008 to 2018.The mortality rate of asthma in 0-19-year old people in China is at the low level around the world.

Objective@#To examine increases in average height among Chinese children and adolescents.@*Methods@#The data were obtained from the China Health and Nutrition Survey conducted during the period 1989-2015. A stratified multistage cluster sampling method was utilized to select participants aged 2-22 years in each province. Linear regression was used to examine the effects of age, birth cohort, and survey period on height.@*Results@#A total of 15,227 males and 13,737 females were included in the final analysis. Age (A) showed a continuous effect on height. The average heights of the investigated groups increased continuously during the investigation period. By 2015, the average height of the overall group increased by 7.87 cm compared to the average height during the 1989 survey. Moreover, birth year (cohort, C) also had a stable effect on height. Using the height of individuals born in or before 1975 as a reference, the average height of each birth cohort increased in comparison to the previous birth cohort.@*Conclusions@#The height of Chinese children and adolescents was affected by age, period, and cohort effects, and this effect is governed by certain rules. The age-period-cohort model can be used to analyze the trends of children's and adolescent's heights. The findings provide a scientific basis for the formulation of children's and adolescents' growth and development policies in China.

BACKGROUND@#Colorectal cancer (CRC) is the fourth cause of cancer death in China. We aimed to provide national and subnational estimates and changes of CRC premature mortality burden during 2005-2020.@*METHODS@#Data from multi-source on the basis of the national surveillance mortality system were used to estimate mortality and years of life lost (YLL) of CRC in the Chinese population during 2005-2020. Estimates were generated and compared for 31 provincial-level administrative divisions in China.@*RESULTS@#Estimated CRC deaths increased from 111.41 thousand in 2005 to 178.02 thousand in 2020; age-standardized mortality rate decreased from 10.01 per 100,000 in 2005 to 9.68 per 100,000 in 2020. Substantial reduction in CRC premature mortality burden, as measured by age-standardized YLL rate, was observed with a reduction of 10.20% nationwide. Marked differences were observed in the geographical patterns of provincial units, and they appeared to be obvious in areas with higher economic development. Population aging was the dominant driver which contributed to the increase in CRC deaths, followed by population growth and age-specific mortality change.@*CONCLUSIONS@#Substantial discrepancies were observed in the premature mortality burden of CRC across China. Targeted considerations were needed to promote a healthy lifestyle, expand cost-effective CRC early screening and diagnosis, and improve medical treatment to reduce CRC mortality among high-risk populations and regions with inadequate healthcare resources.

Objective@#To analyze the characteristics of the second primary tumor affecting the survival of patients with lymphoma, and to explore the risk factors of death from the second primary tumor.@*Methods@#The medical records and related death information of 1 173 lymphoma patients who had already died with known causes were collected. The basic causes of death and the characteristics of patients who died of the second primary tumor were analyzed. Cox regression model was used to analyze the risk factors of lymphoma patients who died of the second primary tumor.@*Results@#Among the 1 173 patients who had died, 94 (8.0%) died of the second primary tumor, 935 (79.7%) died of the primary lymphoma and 144 (12.3%) died of other diseases. The second primary tumor accounted for 17.5% (38/217) of all causes of death in patients with the survival period of more than 5 years, and the second primary tumor accounted for 28.3% (17/60) of all causes of death in patients with the survival period of more than 10 years. Among 94 cases who died of second primary tumors, 31 died of lung cancer, 15 died of gastric cancer, 13 died of liver cancer, 9 died of pancreatic cancer, 6 died of colorectal cancer, 6 died of second primary lymphoma and 14 died of other types of tumors. Univariate Cox regression analysis showed that age, first-line treatment effect, and chest or mediastinal radiotherapy were associated with the death from second primary tumors for lymphoma patients (all P<0.05). Multivariate Cox regression analysis showed that the effect of first-line treatment (P=0.030) and the chest or mediastinal radiotherapy (P=0.039) were independent factors for the death of lymphoma patients from the second primary tumor.@*Conclusions@#The second primary tumor is an important factor affecting the survival of lymphoma patients, and the risk of death from second primary tumors increases significantly over time. The effect of first-line treatment and radiotherapy in the chest or mediastinum are independent factors for the death of lymphoma patients from the second primary tumor.

@# BACKGROUND:The aim of this study is to investigate the diagnostic and prognostic value of neutrophil CD64 (nCD64) as a novel biomarker in sepsis patients. METHODS: One hundred fifty-one adult patients diagnosed with sepsis and 20 age-matched healthy controls were enrolled in the study. Patients with sepsis were further subdivided into a sepsis group and a septic shock group. nCD64 expression, serum procalcitonin (PCT) level, C-reactive protein (CRP) level, and white blood cell (WBC) count were obtained for each patient, and Sequential Organ Failure Assessment (SOFA) scores were calculated. RESULTS: nCD64 expression was higher in the sepsis group with confirmed infection than in the control group. The receiver operating characteristic (ROC) curve of nCD64 was higher than those of SOFA score, PCT, CRP and WBC for diagnosing infection. The area under the curve (AUC) of nCD64 combined with SOFA score was the highest for all parameters. The AUC of nCD64 for predicting 28-day mortality in sepsis was signifi cantly higher than those of PCT, CRP, and WBC, but slightly lower than that of SOFA score. The AUC of nCD64 or PCT combined with SOFA score was signifi cantly higher than that of any single parameter for predicting 28-day mortality. CONCLUSION: nCD64 expression and SOFA score are valuable parameters for early diagnosis of infection and prognostic evaluation of sepsis patients.

Objective@#To analyze the disease burden of pancreatic cancer in China in 1990 and 2017.@*Methods@#Province-specific data in China from the Global Burden of Disease Study (GBD) 2017 were used to describe the change of death status, disease burden of pancreatic cancer in Chinese population by specific province and age groups, including incidence, mortality, disability-adjusted life years (DALY), years of life lost (YLL) due to premature mortality and years lived with disability (YLD) in 1990 and 2017. Meanwhile the incidence, mortality, DALY rate, YLL rate, YLD rate were standardized by the GBD global standard population in 2017.@*Results@#In 2017, the new cases of pancreatic cancer, incidence and age-standardized incidence accounted for 83.6 thousand, 5.92/100 000 and 4.37/100 000 in China, with an increase of 230.94%, 180.45% and 49.88% compared with 1990, respectively. The total number of deaths, mortality and age-standardized mortality appeared as 85.1 thousand, 6.02/100 000, 4.48/100 000, with an increase of 236.08%, 184.80% and 47.51% respectively. The incidence and mortality of pancreatic cancer increased with age and accelerated from the age of 55 to 59 both in 1990 and 2017. The highest incidence and mortality showed in 85-89 years old in 2017 and in 90-94 years old in 1990. The standardized DALY rate of pancreatic cancer increased from 71.00/100 000 in 1990 to 94.32/100 000 in 2017, increased by 32.84%. The standardized YLL rate increased from 70.39/100 000 to 93.42/100 000, increased by 32.72%. The standardized YLD rate increased from 0.62/100 000 to 0.90/100 000, increased by 45.80%. In terms of age distribution, DALY rate, YLL rate and YLD rate of pancreatic cancer basically showed an increasing trend with age in 1990 and 2017. In 2017, Jiangsu (7.61/100 000), Shanghai (7.52/100 000) and Liaoning (6.84/100 000) ranked the top three provinces in terms of standardized mortality. Compared with 1990, Henan (104.28%), Sichuan (94.02%) and Hebei (90.39%) saw the fastest increase in standardized mortality.@*Conclusions@#The incidence, mortality and disease burden of pancreatic cancer in China increased significantly from 1990 to 2017. Prevention and control measures should be strengthened to reduce the disease burden of pancreatic cancer.

Objective: To understand the causes of death and long-term prognosis of lymphoma patients. Methods: Data from 6 200 patients with lymphoma admitted to the Department of Lymphoma, Peking University Cancer Hospital, from January 1995 to Decem-ber 2017, were collected. Those who had died and whose causes of death were known were selected. Clinical records and information on death were collected. Results: A total of 1,173 patients were selected, 742 of whom were male (63.3% ), and 431 were female (36.7%). The median age was 56 (8-92) years. There were 77 cases (6.6%) of Hodgkin's lymphoma, 1,095 cases (93.4%) of non-Hodg-kin's lymphoma, and 1 case of unclear pathological classification. Overall population survival was 0-253 months, with a median surviv-al rate of 20 months. The direct causes of death included lymphoma in 688 (58.7%), various infectious diseases in 119 (10.1%), cardio-vascular diseases in 96 (8.2%), secondary primary tumors in 68 (5.8%), and other diseases in 202 cases (17.2%). The underlying causes of death included lymphoma in 936 (79.8%), secondary primary tumors in 94 (8.0%), cardiovascular diseases in 75 (6.4%), respiratory diseases in 32 (2.7%) and other diseases in 36 cases (3.1%). The underlying causes of death in cases wherein survival time exceeded 5 years included lymphoma in 129 (59.4%), secondary primary tumors in 38 (17.5%), cardiovascular diseases in 35 (16.1%), and other dis-eases in 15 cases (6.9%). The underlying causes of death in cases wherein survival time exceeded 10 years included lymphoma in 28 (46.7%), secondary primary tumors in 17 (28.3%), cardiovascular diseases in 7 (11.7%), and other diseases in 8 cases (13.3%). Conclu-sions: Primary tumors remain the main cause of death in patients with lymphoma. After primary tumors, secondary primary tumors and cardiovascular diseases are the most common causes of death, and with the prolongation of survival, the risk of death caused by these factors increases significantly.

Objective To explore the role of curcumin in inducing autophagy and apoptosis of human hepatocarcinoma cell line Huh7, and the effect of autophagy inhibition on curcumin-induced apoptosis. Methods Human hepatocarcinoma cell line Huh7 was cultured using curcumin (5, 10, 20, and 40 μmol/L)-contained medium, and the proliferation ability was detected by CCK-8 kit. After culturing Huh7 cells using 5-40 μmol/L curcumin-contained medium for 48 h, the expression levels of microtubule-associated protein 1 light chain 3 (LC3)-Ⅱ and LC3- were measured by Western blotting, and the ratio of LC3-Ⅱ to LC3- was calculated. The autophagosome was observed under fluorescence microscope. The apoptosis level of Huh7 cells was measured by flow cytometry. Then Huh7 cells were cultured using the medium containing 5 mmol/L autophagy inhibitor 3-methyladenine (3-MA) and 20 μmol/L curcumin, and the apoptotic and autophagic levels were detected. Results CCK-8 assay showed that curcumin could significantly inhibit the proliferation of Huh7 cells in a dose dependent manner (P0.05, P0.01). Western blotting analysis showed that curcumin significantly increased the ratio of LC3-Ⅱ to LC3- (P0.05, P0.01). Immunofluorescence microscopy showed that the number of autophagosome increased after adding 20 μmol/L curcumin. Compared with the Huh7 cells cultured with the medium containing curcumin alone at 20 μmol/L, the the ratio of LC3-Ⅱ to LC3- was significantly decreased in the Huh7 cells cultured with the medium containing curcumin and 3-MA (P0.01), and the number of autophagosome decreased. Flow cytometry showed that the 5-40 μmol/L curcumin significantly induced the apoptosis of Huh7 cells (P0.05, P0.01), and 3-MA combined with curcumin could significantly decrease the apoptosis of Huh7 cells compared with 20 μmol/L curcumin alone (P0.05). Conclusion Curcumin induces the apoptosis of Huh7 cells, inhibits proliferation and increases autophagy level, and inhibition of autophagy can attenuate the apoptotic effect of curcumin on Huh7 cells.
