Trends of heart disease death and prediction of life expectancy without cause of death in Qidong City in 1990-2019 / 公共卫生与预防医学

Objective To analyze the trend of heart disease death and the life expectancy without cause of death in Qidong City, Jiangsu Province from 1990 to 2019, and to provide reference for the prevention and control of heart disease. Methods Data on heart disease deaths among residents in Qidong City from 1990 to 2019 were collected through the Qidong City Death Registration and Monitoring System. The crude mortality rate (CR) and Chinese age-standardized mortality rate (CASR), potential years of life loss (PYLL), average years of life loss (AYLL), potential life loss years rate (PYLLR), life expectancy, and life expectancy without cause of death were calculated, and the annual percentage change (APC) was used to analyze the trend of heart disease death. Using SAS9.2 software, the death trend prediction was conducted by the ARIMA model in time series analysis. Results From 1990 to 2019, 27,762 residents died of heart disease in Qidong City, with a CR of 81.20/100 000 and an APC of 3.734%. There were 12 358 deaths of heart disease in men, with a CR of 73.24/100 000 and an APC of 3.86%, while there were 15 404 deaths of heart disease in women, with a CR of 88.95/100 000 and an APC of 3.63%. CR showed an upward trend (all P < 0.001). The PYLL for heart disease was 66 192.00 person-years, the AYLL was 13.23 person-years, and the PYLLR was 2.16‰. The life expectancy loss from heart disease was gradually increasing: 0.89 years in 1990 to 1.85 years in 2019, with an APC of 0.405% (P<0.001, a statistically significant trend). The prediction results showed that in 2029, the life expectancy after heart disease would reach 88.17 years. Conclusion From 1990 to 2019, the crude mortality rate of heart disease in Qidong City has showed an increasing trend, leading to an increasing loss of life due to heart disease year by year. The mortality rate and life loss of heart disease in women are higher than those in men. Targeted intervention measures should be further adopted to reduce the mortality rate of heart disease among residents in Qidong.

Experimental study of apoptosis induced by Talniflumate in breast cancer cells / 中国医师杂志

Objective:To explore the effect of the mucin modulator Talniflumate (Tal) on breast cancer cells and its synergistic effect after combined with the chemotherapy drug paclitaxel (PTX).Methods:The breast cancer cells were cultured in vitro. Lymphocyte proliferation activity assay (MTS) was used to detect the effects of different concentrations of Talniflumate alone and paclitaxel on the survival rate of breast cancer cells. The effects of the above drugs on the apoptosis of breast cancer cells were detected by flow cytometry. Western blot was used to detect the expression of glucosamine transferase (GCNT3) (the target of Talniflumate) in breast cancer cells before and after the treatment with Talniflumate. Transcriptome sequencing clarified the changes in related signaling pathways after treatment with Talniflumate. Results:Talniflumate promoted the apoptosis of breast cancer cells MCF7 and MDA-MB-231 cells in a concentration-dependent manner. The combination of Talniflumate and paclitaxel had a significant synergistic killing effect in MCF7 cells but not MDA-MB-231 cells. Western blot indicated that GCNT3 was highly expressed in MCF7 cells, while almost no expression in MDA-MB-231 cells; Talniflumate could reduce the expression of GCNT3 in MCF7 cells and after combined with paclitaxel, the expression of GCNT3 was downregulated more significantly. Transcriptome sequencing suggested that Talniflumate can regulate the expression of multiple signaling pathways such as TNF, p53, and SNARE.Conclusions:Talniflumate could induce apoptosis of breast cancer cell. Talniflumate combined with paclitaxel has a significant synergistic effect in killing tumor cells in breast cancer cells with high GCNT3 expression such as MCF7. The mechanism of Talniflumate induce apoptosis of breast cancer cells may be related to multiple signaling pathways such as TNF, p53, and SNARE.

Objective To study and analyze the trend of diabetes death and the impact of life expectancy in Qidong City, Jiangsu Province from 1990 to 2019, and to provide a basis for formulating health policies. Methods Based on the surveillance data of deaths from all causes in Qidong City and the population data over the years from 1990 to 2019, the residents' diabetes mortality and temporal trends were analyzed. Joinpoint4.7.0.0 software was used to calculate relevant indicators including crude mortality (CR), age-standardized rates by China population (CASR), annual percentage change (APC), potential years of life lost (PYLL), and potential years of life lost rate (PYLLR). Results The CR of diabetes in Qidong City from 1990 to 2019 was 15.12/100 000, with a rate of 12.72/100 000 in males and a rate of 17.45/100 000 in females. The total CASR was 7.58/100 000, including 6.47/100 000 for males and 8.59/100 000 for females. Trend analysis showed that the APC of CR and CASR was 9.31% and 5.26% in males, and 8.12% and 4.40% in females, respectively. The APC of CR and CASR in the 45-64 years old group was 2.59% and 4.85%, respectively. The APC of CR and CASR in the 65 years old and above group was 7.20% and 9.79%, respectively. There were statistically significant differences except for the 15-44 years old group. The life expectancy of residents in Qidong City rose from 73.95 years in 1990 to 82.91 years in 2019 (APC=0.38, P<0.001), and life expectancy without diabetes rose from 74.01 years in 1990 to 83.39 years in 2019 (APC=0.39, P<0.001). Conclusion In the past 30 years, the diabetes mortality and life loss of residents in Qidong City have been increasing year by year and the trend is obvious. Women's diabetes mortality and life loss are higher than those in men. The level and increase rate of diabetes mortality in the high age group are higher than those in the low age group. It is necessary to carry out key intervention for the corresponding population.

Objective To understand the death status, mortality trend, cause of death and life loss of injury and poisoning among residents in Qidong City, Jiangsu Province from 1990 to 2019, and to provide a reference for formulating public health policies. Methods Data on injury and poisoning death of residents in Qidong City from 1990 to 2019 were collected through the death cause registration and monitoring system of Qidong City, Jiangsu Province. Indicators such as crude death rate (CR) and standardized death rate (CASR), average years of lost life (AYLL), and potential years of life lost rate (PYLLR) were calculated. Annual percentage change (APC) was used to analyze the trend of death from injury and poisoning. Results From 1990 to 2019, 18 163 residents in Qidong City, Jiangsu Province died of injuries and poisoning. The CR was 53.12/100 000 (APC=0.74%), and the CASR was 39.43/100 000 (APC=-1.86%). The male CR was 66.90 100 000 (APC=0.75%), and the male CASR was 52.42/100 000 (APC=-1.75%), while the female CR was 39.69/100 000 (APC=0.73%), and the female CASR was 26.63/100 000 (APC=-2.14%). Analysis of the standardized mortality rate showed a downward trend year by year (P<0.001). PYLL caused by injury and poisoning was 318 502.50 person-years (APC=-4.00%), AYLL was 26.02 years/person (APC=-3.26%) and the PYLLR was 10.39‰ (APC=-3.54%). The top five death causes of injury and poisoning are motor vehicle accidents, suicide, drowning, accidental falls and accidental poisoning, accounting for 87.17% of the total deaths from injuries and poisoning. Drowning was the leading cause of death for children aged from 0 to 14. Motor vehicle accidents were the leading cause of death for residents aged from 15 to 64, and accidental falls were the leading cause of death for residents over 65. Conclusion Injury and poisoning are one of the main causes of death among residents in Qidong City, Jiangsu Province. The distribution characteristics of injurie and poisoning deaths of different genders and ages are different. According to their distribution characteristics, targeted and specific measures should be taken to reduce mortality.

APOBEC3B mediated the resistance to cisplatin in non-small cell lung carcinoma / 中国医师杂志

Objective:APOBEC3B (A3B) is an important member of the apolipoprotein B mRNA editing enzyme catalytic polypeptide (APOBEC) family. The study aims to investigate the relationship between A3B expression and prognosis as well as resistance to cisplatin in non-small cell lung cancer (NSCLC).Methods:Real-time quantitative polymerase chain reaction (qRT-PCR) was used to analysis the A3B mRNA expression in 40 NSCLC tissues; Kaplan Meier plotter was used to analyse the correlation between A3B expression and clinical prognosis; in addition, the knock-down A3B expression cell line in human lung adenocarcinoma cell A549 was constructed; MTS and plate cloning experiment were performed to observe the changes in cell cisplatin sensitivity, and γ-H2AX immunofluorescence was used to quantitate the DNA damage.Results:Compared with adjacent tissues, A3B was highly expressed in NSCLC tissues (27/40). Kaplan Meier plotter analysis showed that A3B expression was positively correlated with NSCLC overall survival (OS) [adenocarcinoma: HR=0.64(0.47-0.86), P=0.002 6; squamous cell carcinoma: HR=0.77(0.59-1.01), P=0.006]. Cell-based studies showed that the knock-down A3B expression contributed to sensitivity to cisplatin in A549 cells. Conclusions:A3B mediates the sensitivity of lung cancer to cisplatin. This effect may partly explain why NSCLC patients with high A3B expression have a better prognosis.

Long-term survival trends of bladder cancer from 1972 to 2011 in Qidong / 中国癌症杂志

Background and purpose:There are few studies referring to population-based cancer survival of bladder cancer for more than forty years in China. This paper was to offer basis for assessing long-term survival trends of bladder cancer and the prognosis of this cancer through analysis of the survival rates based on cancer report documents from 1972 to 2011 in Qidong.Methods:The deadline of the last follow-up for survival status of the 1 619 registered cases was Apr. 2012. Cumulative observed survival rate (OS) and relative survival rate (RS) were calculated using Hakulinen’s method performed by the SURV3.01 Software which is developed by Finnish Cancer Registry.Results:The one-, three-, five-, ten-, fifteen-, twenty-, and thirty-year OS rates were 59.91%, 43.49%, 35.98%, 26.91%, 21.30%, 18.37% and 12.24%; and the one-, three-, five-, ten-, fifteen-, twenty-, and thirty-year RS rates were 64.07%, 53.02%, 50.06%, 52.42%, 59.59%, 76.39% and 115.75%, respectively. For males, these OS rates were 60.84%, 43.91%, 36.95%, 27.31%, 21.49%, 18.29% and 12.59%, and RS rates were 65.23%, 53.95%, 52.02%, 54.57%, 62.59%, 79.12% and 117.07%, respectively; For females, these OS rates were 56.61%, 42.03%, 32.44%, 25.65%, 20.78%, 18.80% and 0%, and RS rates, 59.99%, 49.91%, 43.37%, 45.86%, 51.21%, 69.02% and 0%, respectively. There were no statistical differences couldbe found between both sexes (P=0.256). Five-year RS rates of age groups 15-34, 35-44, 45-54, 55-64, 65-74, and more than 75 were 49.10%, 67.53%, 62.77%, 53.92%, 46.59% and 39.85%, and 10-year RS rates, 49.79%, 61.23%, 52.99%, 48.21%, 54.94% and 51.21%, respectively. Remarkable improvement could be seen for the five-, ten-, and fifteen-year RS rates in this setting since 1980’s.Conclusion:The survival outcome from Qidong registered cases with bladder cancer shows gradual progress during the past 2 decades. Early detection and improvement of therapies may be the factors affecting the prognosis of bladder cancer. Although the disparities in survival rates between Qidong and the developed countries are getting narrower, potential for survival improvement still exists.

Intramuscular schwannoma: clinical and magnetic resonance imaging features

<p><b>INTRODUCTION</b>Schwannomas that arise within the muscle plane are called intramuscular schwannomas. The low incidence of these tumours and the lack of specific clinical features make preoperative diagnosis difficult. Herein, we report our experience with intramuscular schwannomas. We present details of the clinical presentation, radiological diagnosis and management of these tumours.</p><p><b>METHODS</b>Between January 2011 and December 2013, 29 patients were diagnosed and treated for histologically proven schwannoma at the National University Hospital, Singapore. Among these 29 patients, eight (five male, three female) had intramuscular schwannomas.</p><p><b>RESULTS</b>The mean age of the eight patients was 40 (range 27-57) years. The most common presenting feature was a palpable mass. The mean interval between surgical treatment and the onset of clinical symptoms was 17.1 (range 4-72) months. Six of the eight tumours (75.0%) were located in the lower limb, while 2 (25.0%) were located in the upper limb. None of the patients had any preoperative neurological deficits. Tinel's sign was present in one patient. Magnetic resonance (MR) imaging showed that the findings of split-fat sign, low signal margin and fascicular sign were present in all patients. The entry and exit sign was observed in 4 (50.0%) patients, a hyperintense rim was observed in 7 (87.5%) patients and the target sign was observed in 5 (62.5%) patients. All patients underwent microsurgical excision of the tumour and none developed any postoperative neurological deficits.</p><p><b>CONCLUSION</b>Intramuscular schwannomas demonstrate the findings of split-fat sign, low signal margin and fascicular sign on MR imaging. These findings are useful for the radiological diagnosis of intramuscular schwannoma.</p>
