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.

Objective:To explore the difference of high-risk factors between early-onset and late-onset pre-eclampsia, and to further understand high-risk factors of pre-eclampsia.Methods:Clinical data of pre-eclampsia pregnant women in 160 medical institutions in China in 2018 were retrospectively analyzed, including 8 031 cases of early-onset pre-eclampsia and 12 969 cases of late-onset pre-eclampsia. The proportion of high-risk factors, different body mass index (BMI) and age stratification between early-onset group and late-onset group were compared.Results:(1) Univariate analysis of high-risk factors: the proportions of high-risk factors in early-onset group and late-onset group were compared, and the differences were statistically significant (all P<0.05). Among them, the proportions of primipara and multiple pregnancy in early-onset group were lower than those in late-onset group, while the proportions of pregnant women with advanced age, irregular antenatal examination, obesity, family history of hypertension, pre-eclampsia, diabetes, kidney diseases, immune system diseases and assisted reproductive technology were higher than those in late-onset group. (2) Hierarchical analysis of BMI: the proportion of pregnant women with BMI≥24 kg/m 2 in early-onset group [48.2% (2 828/5 872) vs 45.5% (4 177/9 181), respectively; P=0.001] and the proportion of pregnant women with BMI ≥28 kg/m 2 in early-onset group [19.5% (1 143/5 872) vs 18.0% (1 656/9 181), respectively; P=0.028] were significantly higher than those in late-onset group. (3) Age stratification analysis: the proportion of pregnant women aged 35-39 years in the early-onset group [21.8% (1 748/8 023) vs 17.5% (2 110/12 068), respectively; P<0.01], the proportion of pregnant women 40-44 years old [6.8% (544/8 023) vs 5.4% (648/12 068), respectively; P<0.01], and the proportion of pregnant women ≥45 years old [0.7% (58/8 023) vs 0.5% (57/12 068), respectively; P=0.021] were significantly higher than those in the late-onset group. (4) Multivariate analysis: advanced age (≥35 years old), multiple pregnancy, irregular antenatal examination or transfer from other hospitals, family history of hypertension (including paternal, maternal and parental lines), previous history of pre-eclampsia, kidney diseases, immune system diseases (systemic lupus erythematosus, antiphospholipid antibody syndrome) and assisted reproductive technology pregnancy were the risk factors affecting the severity of pre-eclampsia (all P<0.05). Conclusion:Pregnant women with high risk factors such as age ≥35 years old, BMI ≥24 kg/m 2 before pregnancy, family history of hypertension, history of pre-eclampsia, chronic kidney diseases, immune diseases (mainly including systemic lupus erythematosus and antiphospholipid syndrome) and assisted reproductive technology are more likely to have early-onset pre-eclampsia.

Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.

Objective:To investigate the current status of quality of life and related health factors of stroke patients and explore the correlation between quality of life and related health factors of stroke patients.Methods:Using the convenient sampling method, a total of 110 stroke patients who were admitted to People's Hospital of Xinjiang Uygur Autonomous Region from March 2018 to March 2020 were selected as the research objects. A questionnaire survey of stroke patients was carried out using general information questionnaires, Stroke Specific Quality of Life Scale (SS-QOL) , Health Promoting Lifestyle ProfileⅡ (HPLPⅡ) and Champion Health Belief Model Scale (CHBMS) to analyze the correlation between their quality of life and related health factors by Pearson correlation analysis. A total of 110 questionnaires were distributed and 103 valid questionnaires were recovered. The effective recovery rate was 93.64%.Results:The total scores of SS-QOL, HPLP Ⅱ, and CHBMS of 103 stroke patients were respectively (115.37±25.43) , (122.38±18.94) and (97.45±15.31) . The total score of SS-QOL in stroke patients was positively correlated with the total score of HPLP Ⅱ ( r=0.564, P<0.05) ; The scores of perceived disease susceptibility and perceived health behavior of CHBMS were positively correlated with the score of each dimension of SS-QOL ( P<0.05) . Conclusions:The quality of life of stroke patients is related to related health factors, suggesting that quality of life of stroke patients can be improved by improving the healthy behavior and belief of them in clinical practice.

Objective: To analyze the expression and prognostic significance of esophageal squamous cell carcinoma associated long non-coding RNA-1 (ESCCAL-1) in esophageal squamous cell carcinoma (ESCC) tissues. Methods: From August 2011 to May 2013, 73 patients with ESCC, who received radical resection in The First Affiliated Hospital of Zhengzhou University and Henan Cancer Hospital, were enrolled. The expressions of ESCCAL-1 in esophageal tumor tissues and corresponding adjacent non-tumor tissues were detected by quantitative real-time polymerase chain reaction (qRT-PCR). T test, chi square test and multivariate analysis were performed for statistical analysis. Results: The expression of ESCCAL-1 was 28.03±9.37 in esophageal tumor tissues of patients with ESCC, which was higher than that in corresponding adjacent normal tissues (11.39±4.15), and the difference was statistically significant (t=2.964, P<0.01). However there were no statistically significant differences in the expressions of ESCCAL-1 among the patients with different age, gender, histological grade, classification of Union for International Cancer Control (UICC), T stage or lymph nodes metastasis (all P>0.05). The median disease-free survival (DFS) time and overall survival (OS) time of patients with low ESCCAL-1 expression were 39 months and 42 months, respectively, which were longer than those of patients with high ESCCAL-1 expression (30 months and 37 months), and the differences were statistically significant (χ²=9.049, P=0.003; χ²=10.165, P=0.001). The results of multivariate analysis showed that ESCCAL-1 expression was the independent risk factor of DFS and OS (high risk (HR)=2.45, 95% confidence interval (CI) 1.22 to 4.93, P=0.012; HR=2.29, 95%CI 1.14 to 4.59, P=0.019). Conclusions ESCCAL-1 may be involved the genesis and development of ESCC. The expression of ESCCAL-1 in esophageal tumor tissues may be a prognostic parameter for patients with ESCC receiving radical resection.

Objective To explore the expression and clinical significance of proliferation associated antigen Ki-67 in acute myeloid leukemia (AML). Methods A total of 45 AML patients (including 36 newly diagnosed AML patients and 9 recurrent AML patients) and 20 healthy volunteers (healthy group) were enrolled from October 2012 to January 2016 in Department of Hematology in Fuxing Hospital. The expression of Ki-67 in bone marrow blast cells were detected by flow cytometry (FCM). The relation between Ki-67 level and clinical characteristics, and the prognostic significance of Ki-67 were studied. Results The positive rate of Ki-67 in newly diagnosed AML, recurrent AML patients and healthy controls were (10.38±8.41)%, (20.99± 11.49) % and (40.77±11.97) %, respectively. The positive rate of Ki-67 in newly diagnosed AML patients or recurrent AML patients were significantly lower than that in healthy controls (all P<0.05). The positive rate of Ki-67 in newly diagnosed AML patients was significantly lower than that in recurrent AML patients (P=0.006). The level of Ki-67 in newly diagnosed AML patients did not significantly correlated with age, FAB subtype, white blood cell count, a history of myelodysplastic syndrome (MDS), level of lactate dehydrogenase (LDH), proportion of blats cells, NPM1 gene mutation, FLT3-internal tandem duplication (ITD) gene mutation, chromosome karyotype and response to induction therapy (all P>0.05). There was no significant difference of overall survival between high Ki-67 expression group and low Ki-67 expression group in newly diagnosed AML patients [(780±110) d vs. (788±118) d, P=0.927]. Conclusions The proliferation of blast cells in AML patients is lower than that in healthy controls. Detecting the level of Ki-67 may provide a reference for choosing the cell cycle specific chemotherapy drugs in clinical practice. Monitoring Ki-67 during AML process contributes to monitoring disease progression and predicting recurrence.

Objective: To study the relationship between morphological characteristics, grading, diagnosis and prognosis in phyllodes tumors (PT) of the breast. Methods: A retrospective study was carried out on 83 PTs diagnosed between 1999 and 2003 that were classified semi-quantitatively according to the WHO recommendation. Follow-up data was available for some cases, and Cox regression analysis was used to evaluate factors affecting metastasis and recurrence. Results: All cases were classified into the benign (57.8%), borderline (28.9%) and malignant (13.3%). The overall recurrence rate for the 72 cases with follow-up data was 20.8% (15/72), and was 17.5% (7/40) in benign, 22.7% (5/22) in borderline and 3/10 in malignant PT, respectively, with no significant difference (P>0.05). The median interval between the initial diagnosis and the first recurrence was 24 months. Lung or bone metastases occurred in 1/22 borderline and 3/10 malignant PT patients 5 years post-surgery. The mitotic count and the degree of stromal cell atypia were significantly correlated with recurrence (P=0.001 and P=0.006). Multivariate analysis showed that severe stromal cell atypia was an independent predictor of recurrence-free survival in PT [HR=6.40 (95% CI=1.378 to 29.732), P=0.018]. Conclusions Each parameter in the histological grading of PT may have different prognostic value, and markedly increased mitotic count and were predictive of relapse.

Objective To study the clinical efficacy of autologous peripheral blood stem cell transplantation for the treatment myocardial infarction,in the same period of coronary artery bypass grafting (CABG).Methods From January 2012 to January 2015,76 patients with myocardial infarction were selected.Patients were divided into transplantation group (n =46) and control group (n =30) on the basis of whether being treated by autologous peripheral blood stem cell transplantation.After myocardial infarction patients were taken to the hospital with the therapy of conventional drug,5 days before CABG,transplantation group was given the autologous peripheral blood stem cell mobilization and expansion,24 hours before CABG,taking autologous peripheral blood stem cell collection.76 patients took CABG with non-cardiopulmonary by pass,transplantation group was given autologous peripheral blood stem cell via transplantation vessels and subepicardial,while the control group was not given the injection of autologous peripheral blood stem cell.The LV morphology,wall motion score index (WMSI) and index of cardiac function before and after the operation in both groups were evaluated by echocardiography.Results Six months after CABG,there was a significant decrease in Left ventricular end-diastolic diameter and wall motion score index,Left ventricular ejection fraction was increased.The indexes of cardiac function in the transplantation group were better than the control group.Conclusion Autologous peripheral blood stem cell transplantation for the treatment myocardial infarction can improve the heart function,and has obvious recent clinical curative effect in the same period of CABG.

Purpose To assess the clinical and pathological features of small gastrointestinal stromal tumours (sGIST).Methods To reevaluated the clinical,histological and immunohistochemical parameters of 21 sGISTs.The standard immunohistochemical panel antibodies were studied on the tumor sections.All data were compared with clinical sGIST.Results There were a total of 7 females and 14 males of sGISTs.The median age was 63 years old.The tumors were predominantly located in the stomach showing a spindle cell morphology and the tumor sizes ranged from 0.5 cm to 1.5 cm.9 sGISTs combined with malignant tumors,which were gastric cancer have been incidentally detected during surgery.As the lesions were small in size,with infrequent bleeding,necrosis,mucosal invasion,ulceration and less mitotic index,sGISTs reoccurred less compared with clinical sGIST.p53,Ki-67 labeling index and microvascular density (MVD) in sGIST were significantly lower than clinical sGIST (P ＜ 0.05).Conclusion sGIST may occure with digestive tract cancer synchronously.p53,Ki-67 labeling index and MVD were lower than clinical GIST,which means better prognosis.
