Objective To analyze micronucleus abnormalities in the peripheral blood lymphocytes of industrial radiation workers and the influencing factors, and to provide a reference for radiation protection. Methods The occupational health monitoring data of 661 industrial radiation workers were collected from the occupational health examination system of Gansu Provincial Center for Disease Control and Prevention. The abnormalities in the micronucleus of peripheral blood lymphocytes were analyzed. The influencing factors were identified by logistic regression. Results The micronucleus abnormality rate was 6.05% for the 661 industrial radiation workers. There was no significant difference in micronucleus abnormality rate between sexes (P > 0.05). Comparison of age groups showed that the rate of micronucleus abnormality increased with age, and workers over 50 years of age has the highest rate of micronucleus abnormalities (17.81%); there was a significant difference between age groups (P < 0.05). There was a significant difference in micronucleus abnormality rate between occupational categories (P < 0.05). There was a significant difference in micronucleus abnormality rate between groups with different years of work (P < 0.05). Logistic regression analysis showed that age and years of work were the risk factors for micronucleus abnormality rate (P < 0.05); age was an independent risk factor for micronucleus abnormality rate (P < 0.05). Conclusion The effect of low-dose ionizing radiation on micronucleus abnormality rate of industrial radiation workers is related to age and working years. Attention should be paid to occupational health monitoring of radiation workers, especially those with advanced age.

The Roles of Small Extracellular Vesicles and Small Extracellular Vesicles-derived Non-coding RNA in Non-alcoholic Fatty Liver Disease / 生物化学与生物物理进展

Extracellular vesicles (EVs) are a kind of exsomes secreted by cells, which all cells release them as part of their normal physiology and during acquired abnormalities. EVs can be broadly divided into two categories by their sizes, small EVs (sEVs) and medium/large EVs (m/l EVs). As a kind of extracellular vesicle, sEVs are mostly discoid vesicles with diameters ranging from 40 nm to 200 nm. The medium/large EVs are elliptical with a diameter more than 200 nm. sEVs play a crucial role in intercellular communication and have emerged as important mediators in the development and progression of liver diseases. In this review, we discussed the current understanding of the role of sEVs, particularly sEV derived non-coding RNA in non-alcoholic fatty liver disease (NAFLD) and their potential as diagnostic and therapeutic targets. sEVs are small membrane-bound particles secreted by cells, which fuse with plasma membrane and release to extracellular matrix. Depending on the cell of origin, sEVs could contain many cell constituents, including various DNA, RNA, lipids, metabolites, and cytosolic and cell-surface proteins, biomolecules. In addition, many RNA and DNA molecules contained by sEVs, such as mRNA, microRNA (miRNA), long noncoding RNA (lncRNA) and mitochondrial DNA (mtDNA), can be transferred to recipient cells to effectively promote their biological response, physiological and pathological functions. Such sEVs-mediated responses can be disease promoting or restraining. The intrinsic properties of sEVs in regulating complex intracellular pathways has advanced their potential utility in the therapeutic control of many diseases. Recent studies reviewed here also indicate a functional, targeted, mechanism-driven accumulation of specific cellular components in sEVs, suggesting that they have a role in regulating intercellular communication. Many studies have also shown the involvement of sEVs’ noncoding RNAs (ncRNAs) in controlling cell activities and their crucial functions in regulating lipid metabolism. sEVs ncRNAs, including miRNAs, lncRNAs, and circular RNAs (circRNAs) regulate physiological functions and maintain lipid metabolism homeostasis. miRNA are small non-coding RNA molecules that regulate posttranscriptional gene expression by repressing messenger RNA-targets. These circulating miRNAs are easily accessible, disease-specific and sensitive to small changes, which makes them ideal biomarkers for diagnostic, prognostic, predictive or monitoring purposes. Specific miRNA signatures can be reflective of disease status and development or indicators of poor treatment response in liver diseases. And lncRNAs have been shown to regulate gene expression by interacting with transcription factors or chromatin-modifying enzymes, which regulate gene expression by binding to target mRNAs. Then circRNAs contributed to NAFLD progression by acting as miRNA sponges, functional protein sponges, or novel templates for protein translation. Finally, sEVs could be engineered to deliver diverse therapeutic payloads, including short interfering RNAs, antisense oligonucleotides and so on, with an ability to direct their delivery to a desired target. The potential of targeting sEVs with lncRNAs and miRNAs not only could be potential diagnostic biomarkers for NAFLD, but also have potential therapeutic effects on NAFLD, which might provide new ideas for the NAFLD treatment. In conclusion, this review provides an overview of the current understanding of the roles of sEVs ncRNAs in NAFLD, so we suggest that further research into sEVs could lead to new diagnostic tools and therapeutic strategies for NAFLD.

Study on chemical compositions and hepatotoxicity of water extract and ethanol precipitate of processed products of Psoralea corylifolia / 中国药房

OBJECTIVE To study the content changes of 5 chemical compositions in water extract and ethanol precipitate of different processed products of Psoralea corylifolia， and to preliminarily evaluate its hepatotoxicity. METHODS The water extracts from crude product of P. corylifolia and processed products by Leigong method， running water rinsing method， and salt stir-frying method were prepared， as well as the ethanol precipitates of processed products by Leigong method and salt stir-frying method were prepared. The contents of psoralenoside， isopsoralenoside， psoralen， isopsoralen and bakuchiol were determined by high- performance liquid chromatography and compared. The median lethal concentration （LC50） and maximum non-lethal concentration （MNLC） of each sample to wild-type zebrafish juveniles were calculated after 72 h of treatment with different concentrations of water extracts from raw product and processed products by running water rinsing method， Leigong method and salt stir-frying method， different concentrations of ethanol precipitates from processed products by Leigong method and salt stir-frying method， and the acetaminophen was used as the positive control. The basic morphology of wild-type zebrafish juveniles and the liver phenotype of transgenic zebrafish juveniles were observed after 72 h of treatment with the above samples （MNLC）. Pearson correlation analysis was used to evaluate the correlation between component content and hepatotoxicity. RESULTS Compared with the water extract of raw products， the contents of psoralenoside and isopsoralenoside in the water extract of different processed products were generally decreased （P＜0.05）， while the contents of psoralen， isopsoralen and bakuchiol in the ethanol precipitate of Leigong method and salt stir-frying products were significantly increased （P＜0.05）. The LC50 of water extracts of crude product and processed products by running water rinsing method， Leigong method， salt stir-frying method， and ethanol precipitates of processed products by Leigong method and salt stir- frying method were 2.45， 5.00， 5.38， 1.55， 2.36， 0.64 g/L （calculated by crude drug）， and MNLC were 2.21， 4.53， 5.02， 1.37， 2.13， 0.53 g/L （calculated by crude drug）. Compared with the blank control group， the zebrafish juveniles in each sample treatment group showed different degrees of deformity， the liver relative fluorescence intensity was significantly weakened （P＜0.05 or P＜ 0.01）. Fat-soluble components such as bakuchiol， isopsoralen and psoralen were highly correlated with liver fluorescence intensity （R 2＞0.7）. CONCLUSIONS The processed products of P. corylifolia mainly compose of psoralenoside and isopsoralenoside after water extraction， the contents of psoralen， isopsoralen and bakuchiol increase after alcohol precipitation， and the hepatotoxicity is positively correlated with the contents of liposoluble compositions in P. corylifolia.

Maxent modeling for predicting the global potential distribution of talaromycosis marneffei / 中国热带医学

@#Abstract: Objective　To predict the potential distribution of talaromycosis marneffei (TSM) and analyze its driving factors, so as to provide evidence for the surveillance and prevention of this disease. Methods　The data of all laboratory-confirmed, non-duplicating TSM published in the English and Chinese literature from the first case in January 1964 to December 2018 was collected. A Maxent ecology model using environmental variables, Rhizomys distribution and HIV/AIDS epidemic was developed to forecast ecological niche of TSM worldwide, as well as identify the driving factors. Results　A total of 705 articles (477 in Chinese and 228 in English) were obtained during the study period. After excluding imported cases, a total of 100 foci information were included in the model. The area under the receiver operating characteristic (ROC) curve (AUC) of the model was 0.997 for the training set and 0.991 for the test set. Maxent model revealed that Rhizomys distribution, mean temperature of warmest quarter, precipitation of wettest month, HIV/AIDS epidemic and mean temperature of driest quarter were the top 5 important variables affecting TSM distribution. In addition to identifying traditional TSM endemic areas (South of the Yangtze River in China, Southeast Asian, North and Northeast India), other potential endemic areas were also identified, including parts of the North of the Yangtze River, Central America, West Coast of Africa, East Coast of South America, the Korean Peninsula and Japan. Conclusion　Our finding has discovered hidden high-risk areas and provided insights about driving factors of TSM distribution, which will help inform surveillance strategies and improve the effectiveness of public health interventions against TM infections.

Pathogenic characteristics of bloodstream infections in patients with hematological diseases and the impact of stem cell transplantation on them / 中国热带医学

@#Abstract: Objective To investigate the epidemiological characteristics of pathogens causing bloodstream infection in hematology patients during treatment and to compare the effects of allogeneic hematopoietic stem cell transplantation (HSCT) on them, so as to provide evidence for the diagnosis and treatment of bloodstream infection. Methods A total of 292 cases with bloodstream infection in hematology wards of the PLA General Hospital were collected from 2017 to 2021, which were divided into HSCT group and N-HSCT group according to whether performed HSCT or not. The epidemiological characteristics and influence of pathogenic bacteria in blood stream infection were analyzed and compared between the two groups. Results A total of 362 strains of pathogenic bacteria were collected from 292 cases, including 106 strains in HSCT group (84 cases) and 256 strains in N-HSCT group (208 cases). Bloodstream infections were more common in acute myeloid leukemia (130/392, 44.52%), followed by non-Hodgkin's lymphoma (74/292, 25.34%). The rate of once bloodstream infection in HSCT group was higher than that in N-HSCT Group, but the rate of twice bloodstream infections in N-HSCT group was higher. Gram-negative Bacilli were the most common pathogens (56.08%), with Escherichia coli being absolutely dominant (109/362, 30.11%), followed by Klebsiella pneumoniae (39/362, 10.77%). Coagulase-negative staphylococci (CoNS) (107/362, 29.56%) were the most common Gram-positive cocci. The detection rate of fungi in HSCT group (10/106, 9.43%) was significantly higher than that in N-HSCT Group (3.52%). The drug resistance rate of the common pathogenic bacteria was at a high level, and there was a certain proportion of multi-drug resistant strains (except for Pseudomonas aeruginosa). The resistance rates of CoNS to penicillin, gentamicin, moxifloxacin, clindamycin and rifampicin in HSCT group were higher than those in N-HSCT Group. The resistance rate of Escherichia coli to piperacillin/tazobactam, cephalosporins and etapenem in HSCT group was significantly higher than that in N-HSCT group. Conclusions The pathogens of blood stream infection in hematology patients are complicated and various. It is difficult for clinical diagnosis and treatment to detect multiple infections and multiple pathogens. HSCT patients have a higher risk of fungal bloodstream infection and more multi-drug resistant strains detected. Therefore, the identification of bloodstream infection and multi-drug resistant strains associated with HSCT patients should prompt surveillance.

Application of fluorescence in situ hybridization technique to verify the clonalities of non-clonal cytogenetic abnormalities identified in Myelodysplastic syndrome / 中华医学遗传学杂志

OBJECTIVE@#To assess the value of fluorescence in situ hybridization (FISH) technique for the verification of the clonalities of non-clonal cytogenetic abnormalities (n-CCA) identified by conventional chromosome banding analysis (CBA) in patients with Myelodysplastic syndrome (MDS).@*METHODS@#Clinical data and results of karyotyping and FISH assays for 91 patients of MDS with n-CCA identified by CBA were retrospectively analyzed. In total 94 non-clonal +8, 5q-, -7/7q- or 20q- were detected by CBA, among which 43 (45.7%) were verified to be clonal abnormalities by FISH.@*RESULTS@#The detection rates for +8, 5q-, -7/7q- and 20q- by FISH were 47.6% (30/63), 25% (2/8), 41.7% (5/12), 40% (2/5) and 66.7% (4/6), respectively, with the positive cells accounting for 4% to 90% of all counted cells, with a median value of 7%. The 91 patients were divided into three groups including ≥ 20, 10 ~< 20 and < 10 based on the numbers of metaphase cells in CBA, and the detection rates by FISH for the three groups were 43.7% (31/71), 33.3% (3/9) and 63.6% (7/11), respectively, which showed no statistically difference (P > 0.05). Continuous CBA and FISH surveys were conducted for 26 patients who received supportive treatment, and the results revealed that 91.7% (11/12) of FISH-verified positive abnormalities had persisted, whereas 92.9% (13/14) of the n-CCA verified as negative by FISH was transient.@*CONCLUSION@#Nearly half of the CBA identified n-CCA have been verified as clonal aberrations by FISH, and the FISH detection rate showed no correlation with the number of metaphase cells. FISH test is strongly recommended for verifying the clonalities of n-CCA detected by CBA, and continuous cytogenetic survey of the patients with MDS is necessary.

Herbal Textual Research on Pruni Semen in Famous Classical Formulas / 中国实验方剂学杂志

This article has systematically sorted out and verified the name， origin， producing area， quality evaluation， harvesting and processing of Pruni Semen by consulting ancient materia medica， medical books， prescription books and modern literature， in order to provide a basis for the development of famous classical formulas containing Pruni Semen. The results showed that Pruni Semen， as a medicinal material， has been widely used in medical literature of past dynasties since it was collected in Shennong Bencaojing， and also included under the names such as Yuhe， Yuzi and Yuli， and aliases such as Jueli， Queli and Chexiali. The primordial plants mentioned in the past dynasties involve about 12 species of Rosaceae， but with Prunus humilis， P. japonica and P. glandulosa as mainstream varieties used in the past dynasties， while the 2020 edition of Chinese Pharmacopoeia stipulates that the basal plants are P. humilis， P. japonica and P. pedunculata. Most of the ancient records for the origin of Pruni Semen are found everywhere in high mountains， valleys and hills， modern literature records that its origin varies according to its base， for example， P. humilis and P. japonica are mainly produced in Hebei， eastern Inner Mongolia， Liaoning， Shandong and other regions of China， and P. pedunculata is mainly produced in Inner Mongolia. Modern literature summarizes its quality as faint yellow， full and fulfilling， neat and not broken， and non-oiling， and the small Pruni Semen is better than the big Pruni Semen. The ancient processing methods of Pruni Semen mainly include blanching and peeling， blanching and peeling followed by frying， and blanching and peeling followed by pounding， with the common feature of blanching and peeling. The successive editions of Chinese Pharmacopoeia stipulate that it should be pounded when used. Based on the results of the herbal textual research and the writing time of Bianzhenglu， and combined with the market survey of Pruni Semen， it is suggested that P. humilis or P. japonica should be used as the origin of Pruni Semen in Sanpiantang， and it is harvested when the fruits are ripe， the kernels are collected by removing the stones， and processed by blanching， peeling and pounding consulting the decoction method in the current edition of Chinese Pharmacopoeia.

Construction of predictive model for pregnancy-related anxiety risk in pregnant women based on LASSO regression / 环境与职业医学

Background Pregnancy-related anxiety has a negative impact on the physical and mental health of pregnant women and the normal growth and development of the fetus. Establishing prediction models for pregnancy-related anxiety to screen associated predictive factors may provide important opportunities for prenatal intervention. Objective To establish a prediction model of pregnancy-related anxiety risk of pregnant women. Methods From January to July 2021, a questionnaire survey on pregnancy-related anxiety and predictors was conducted among pregnant women having routine prenatal check-ups provided by an obstetrics clinic of a tertiary grade A hospital in Ningxia. The socio-demographic characteristics of the subjects were collected, and the pregnant women were evaluated by the Life Event Scale (LES), Perceived Social Support Scale (PSSS), Family APGAR Index (APGAR), and Pregnancy-related Anxiety Questionnaire (PAQ). R 4.2.0 software was used to fit all selected variables by least absolute shrinkage and selection operator (LASSO) regression to identify predictors of pregnancy-related anxiety in the second and third trimesters. On the basis of logistic regression analysis, prediction models of pregnancy-related anxiety in the second and third trimesters were constructed, and the model nomogram and receiver operating characteristic curve (ROC) were drawn. The prediction effect of the model was evaluated by area under the curve (AUC). A calibration chart was drawn to evaluate the calibration of the model. Results A total of 1500 questionnaires were distributed, and 1448 valid questionnaires were recovered, with an effective rate of 96.53%. Among the 1448 pregnant women, the overall positive rate of pregnancy-related anxiety was 28.80% (417/1448), and the positive rates in the second and third trimesters were 29.21% (276/935) and 27.49% (141/513), respectively. The predictors entering the the second trimester model were age of marriage, family care, social support, family expectations for the fetus, physical condition during pregnancy, and whether experiencing life stressful events during pregnancy. The predictors entering the the third trimester model were pregnancy intention, physical discomfort, and whether experiencing life stress during pregnancy. A risk prediction model of pregnancy-related anxiety for the second trimester was established: risk of pregnancy-related anxiety=−0.07× marriage age +0.12× family care −0.03× social support −0.65× family expectation of fetal sex +0.42× physical condition during pregnancy +0.47× whether experiencing life stressful events during pregnancy. A risk prediction model of pregnancy-related anxiety for the third trimester was established: risk of pregnancy-related anxiety=−5.69+0.82× pregnancy intention +1.06× physical discomfort +0.94× whether experiencing life stressful events during pregnancy. The ROC curves of the two models were drawn. The AUC of the second trimester model was 0.71, and the AUC of related validation model was 0.68. The AUC of the third trimester model was 0.72, and the AUC of related validation model was 0.66. Conclusion The risk prediction models of pregnancy-related anxiety constructed based on LASSO regression and logistic regression have good prediction ability, and they suggest that pregnant women in the second trimester with short marriage age, high family care, low social support, family expectations for fetal sex, average physical condition, and experiencing life stress during pregnancy, and pregnant women in the third trimester with spontaneous pregnant intention, unintended pregnancy, physical discomfort, and experiencing life stress during pregnancy are high-risk groups for pregnancy-related anxiety.

OBJECTIVE@#To investigate the clinical and prognostic characteristics of primary acute myeloid leukemia (AML) with 11q23/KMT2A rearrangements.@*METHODS@#Clinical data of 90 patients with primary AML and 11q23/KMT2A rearrangements were analyzed retrospectively.@*RESULTS@#By karyotyping analysis, 80 of the 90 patients had translocations involving 11q23/KMT2A, with t(9;11)(p22;q23), t(6;11)(q27;q23), t(10;11)(p12;q23) and t(11;19)(q23;p13) being the most common ones, while 10 cases were found to have non-translocation abnormalities. The overall complete remission (CR) rate was 75.6%, and patients with t(6;11) had lower CR rate compared with non-t(6;11) patients (47.1% vs. 82.2%, P = 0.005). After a median follow-up of 24.5 months, the patients receiving allo-hematopoietic stem cell transplantation (allo-HSCT) had significantly higher 3-year overall survival (OS) (80.3% vs. 16.6%, P < 0.001) and 3-year event-free survival (EFS) (73.5% vs. 16.3%, P < 0.001) compared with non-transplant patients. Patients with t(6;11) had the lowest 3-year OS (11.8% vs. 56.0%, P < 0.001) and 3-year EFS (5.9% vs. 53.8%, P < 0.001) compared with other type of abnormalities. No significant difference was noted in the survival between patients with t(9;11) and non-t(9;11) regardless whether they had received HSCT.@*CONCLUSION@#The clinical characteristics of primary AML with 11q23/KMT2A rearrangements are heterogeneous. Patients did not receive HSCT had poorer survival, particularly with the presence of t(6;11). Allo-HSCT could significantly improve the survival of such patients.

Analysis of clinical characteristics of ovarian clear cell carcinoma in perimenopausal women based on ultrasound imaging / 中华老年医学杂志

Objective:To examine the ultrasound images, clinical features, intraoperative conditions, and pathological features of ovarian clear cell carcinoma(OCCC)during perimenopause, in order to improve the early diagnosis of OCCC via ultrasound examination.Methods:A retrospective analysis of 29 patients, aged 42-72(56.8±7.4)years, who were surgically treated and pathologically diagnosed with OCCC at our hospital between 1 September 2015 and 31 December 2022, including 10 in the non-menopausal phase, 3(10.3%)in early menopausal transition, 7(24.1%)in late menopausal transition, and 19(65.5%)in the post-menopausal phase.The number of pregnancies(1.86±1.04)and the number of births(0.97±0.56)were also recorded.Results:In 29 cases, the masses contained solid components, and the ultrasound manifestations were as follows: (1)single-compartment cystic masses(solid components accounted for <50% of the total volume)were found in 11 cases, with clear borders, regular morphology, ground-glass echoes inside the cystic cavity, multiple solid protrusions inside the cystic cavity, and blood flow signals inside the solid components on color Doppler flow imaging(CDFI); (2)multi-compartment cystic masses(solid components accounted for <50% of the total volume)occurred in 8 cases, with largely clear borders, ground-glass echoes inside the cystic cavity, multiple solid protrusions inside the cavity, thick walls where the protrusions were attached, varying thickness of walls separating the cystic cavities, and blood flow signals inside the solid components, walls where there were solid attachments and thicker parts of the separating walls on CDFI; (3)there were 7 cases with predominantly solid cystic masses(the solid components accounted for >50% of the total volume), unclear borders, poor translucency, irregular morphology of the solid components, uneven internal echoes, and blood flow signals in the solid component on CDFI; (4)solid masses(the solid components accounted for >95%of the total volume)were seen in 3 cases with unclear borders, irregular morphology, uneven internal echoes, and a small number of cystic cavities(cystic portion <5%), with poor translucency in the cystic cavities and blood flow signals in the solid components on CDFI.Intraoperative exploration of ascites was performed in 17 cases, and adhesion between the mass and surrounding organs was found in 27 cases.Postoperative pathological results revealed 26 cases with high grade tumors and 3 cases with intermediate grade tumors.There were 3 cases with bilateral OCCC, 13 with left side OCCC and 13 with right side OCCC.According to the FIGO pathological staging system, 12 cases were in stage Ⅰ, 10 in stage Ⅱ, 5 in stage Ⅲ and 2 in stage Ⅳ.Comparison of different pathological stages(early stages Ⅰ and Ⅱ versus late stages Ⅲ and Ⅳ)showed statistically significant differences in the ratio of pathological stages between patients with different ultrasonographic manifestations( χ2=11.163, P<0.05), and the results of two-by-two comparisons showed that OCCC patients with ultrasonographic manifestations of solid masses(solid component accounting for >95%of the total volume)were more often in the late stage at the time of onset, while OCCC patients with a high number of cystic components within the lesions were more likely to be in the early stage at the time of onset.OCCC patients with more cystic components in the lesions tended to have an earlier onset and a better prognosis. Conclusions:When ultrasound imaging shows primarily a single chamber cystic solid mass in a patient in the perimenopausal phase with an endometriosis history, together with signs of specialized examination and pelvic adhesion during transvaginal sonography, a diagnosis of OCCC should be suspected.It is of great significance to pay attention to transvaginal sonography examination, ultrasound image features and clinical symptoms in perimenopausal women for the early diagnosis of OCCC.

Mortality and years of life lost of pancreatic cancer in Baoshan District of Shanghai from 2009 to 2021 / 上海预防医学

ObjectiveTo investigate the mortality and years of life lost of pancreatic cancer in Baoshan District of Shanghai，from 2009 to 2021， and to provide scientific evidence for the prevention and control of pancreatic cancer in the future. MethodsThe death surveillance data of Baoshan District from 2009 to 2021 were collected from the Shanghai chronic disease surveillance information management system. Crude mortality， standardized mortality，potential years of life lost （PYLL）， potential years of life lost rate （PYLLR） ， average years of potential life lost （AYLL） ， annual percentage change （APC） were calculated to analyze the trend of mortality and life loss of pancreatic cancer. ResultsFrom 2009 to 2021， a total of 2117 deaths of pancreatic cancer were reported in Baoshan District， accounting for 7.05% of all cancer deaths. The average age of the death cases was （71.18±10.97）years. The youngest was 3 years old and the oldest was 96 years old. The death component ratio of pancreatic cancer increased with time （P<0.05）， and the average death age of women was higher than that of men （P<0.05）. The crude mortality of pancreatic cancer was 17.38/105 in Baoshan District from 2009 to 2021， showing a rising tendency （P<0.05） with APC of 3.74%. The standardized mortality of pancreatic cancer was 7.84/105. The crude mortality of pancreatic cancer was 19.71/105 in men and 14.89/105 in women， both showed a tendency towards a rise （P<0.05 ） with APC of 4.44% and 2. 89%， respectively. The crude mortality of pancreatic cancer showed a tendency towards a decline in residents at ages of 45 to 60 years （ P<0.05 ）， with APC of 4.74%. The PYLL and PYLLR of pancreatic cancer were 8 115 person-years and 0.67‰ in Baoshan District from 2009 to 2021， while the AYLL of pancreatic cancer was 3.83 years per person. The PYLL was higher in men than in women. ConclusionThe mortality rate of pancreatic cancer in Baoshan District shows an increasing trend. The healthy life of elderly and men is affected largely by pancreatic cancer. It is necessary to strengthen the health education on the prevention/control of pancreatic cancer and healthy life style， thereby improving the tertiary prevention system of pancreatic cancer.
