Objective To investigate the expression of CXC chemokine receptor 1 (CXCR1) and CXC chemokine receptor 2 (CXCR2) in triplenegative breast cancer (TNBC) and its significance.Methods The EnVision immunohistochemistry system was used to detect the expression of CXCR1 and CXCR2 in 28 specimens from normal tissues adjacent to breast cancer,30 specimens of invasive ductal carcinoma not otherwise specified (IDC-NOS),and 34 TNBC specimens.The relationship between the expression of CXCR1 and CXCR2,and clinical pathological features was analyzed.Results In the adjacent normal tissues of breast cancer,the positive expression rates of CXCR 1 and CXCR2 were 89.3％ and 92.9％,respectively;CXCR1 and CXCR2 expression displayed no significant association with clinicopathological parameters such as age,tumor size,or Scarff-Bloom-Richardson (SBR) score.The positive expression rates of CXCR1 and CXCR2 were 63.3％ and 60.0％,respectively,in the IDC-NOS samples and 23.5％ and 35.3％,respectively,in the TNBC samples.There was a positive correlation between CXCR1 and CXCR2 expression in the TNBC samples (r =0.606,P ＜ 0.001).Conclusion Correlation of CXCR1 and CXCR2 expression with sample type was strong in adjacent normal tissues,moderate in IDC-NOS samples,and low in TNBC samples.CXCR1 expression was positively correlated with CXCR2 expression in all sample types.The expression of CXCR1 or CXCR2 was closely related to the development and promotion of TNBC.

Objective To evaluate the effect of virtual reality(VR)on cognitive function and quality of life in patients with Parkin-son's disease. Methods A systematic search of CBM,CNKI,Wanfang data,VIP,Cochrane Library,Web of Science,Embase,and PubMed was carried out to identify randomized control trials(RCT)about the effect of VR technology on pa-tients with Parkinson's disease from inception to February 29th,2024.The control group received routine cogni-tive training,balance training or physical therapy,and the experimental group received VR technology.The quali-ty of articles was evaluated using the Cochrane Collaboration's 5.1.0 RCT risk assessment tool for bias.The meta-analysis was performed using Revman5.4.GRADE was used to evaluate the evidence quality of outcome indica-tors. Results A total of 13 literatures involving 426 patients were included.Allocation concealment and blind methods were not described in most literatures,and selective reporting of research results or other biases was unclear.VR tech-nology could improve the Motreal Cognitive Assessment(MoCA)score(MD=1.11,95%CI 0.31 to 1.90,P=0.006),Trail Making Test(TMT)-A score(MD=-6.25,95%CI-11.71 to-0.78,P=0.030)and depression scale score(SMD=-0.56,95%CI-0.95 to 0.18,P=0.004)of patients with Parkinson's disease;however,it did not improve TMT-B score(MD=-6.01,95%CI-28.16 to 16.14,P=0.590),Unified Parkinson's Disease Rat-ing Scale(UPDRS)-Part II score(MD=-2.11,95%CI-4.97 to 0.75,P=0.150)and Parkinson's Disease Ques-tionnaire(PDQ-39)score(MD=-0.92,95%CI-4.03 to 2.19,P=0.560).For quality of evidence,MoCA score,UPDRS-Part II score and PDQ-39 score were low,and depression score and TMT score were moderate. Conclusion VR technology can improve the cognitive function and depression of patients with Parkinson's disease;how-ever,no significant improvement is found in activities of daily living and quality of life.

Objective:To estimate the healthy life expectancy (HALE) of registered residents in Jing′an District, Shanghai City.Methods:From June to August in 2017, 14 districts (towns) were selected as the research sites, and 4 159 registered residents were selected as the subjects. The health status data of subjects were collected by using the self-rated health scale, and the health rate of subjects was obtained by using the CHOPIT model. The health rate of residents under 18 years old was replaced by the parameters of 18-year-old group, and Sullivan method was used to calculate the HALE of registered residents in Jing′an District, Shanghai City.Results:The age of 4 159 subjects was (56.46±15.19) years old, ranging from 18 to 98 years old. There were 1 768 males (42.5%). The overall health rate of subjects was 74.96%, of which the health rates of male and female were 76.87% and 72.45% respectively. With the increase of age, the health rate decreased ( Z=265.51, P<0.001), and the health rate of male was higher than that of female (χ2=2 154.54, P<0.001). The HALE of the 0-year-old group was 64.29 years old, in which the male and female were 66.25 and 63.57 years old respectively. Among the 18-year-old group, the HALE was 48.18 years old, with 49.07 years old for male and 47.46 years old for female. The HALE of male was higher than that of female in all age groups. With the increase of age, the HALE decreased gradually. Conclusion:There are significant sex and age differences in HALE in Jing′an District, Shanghai City. The health issue of female and older people should be given more attention.

Objective:To investigate the scientific research ability of undergraduate nursing interns and to analyze the mediating effect of professional identity between achievement motivation and scientific research ability among undergraduate nursing interns.Methods:From November 2019 to December 2019, this study selected 198 nursing undergraduates interning at a ClassⅢ Grade A hospital in Hefei as subjects by convenience sampling. All nursing undergraduates were investigated with the General Information Scale, Scientific Research Ability Self-evaluation Rating Scale of Nursing Staff, Professional Identity Scale for Nurses and Achievement Motivation Scale.Results:Among those undergraduate nursing interns, the total score of scientific research ability was (59.60±22.98) with the highest score in the capacity of writing a research report and the lowest score in the capacity of generating the research idea. Multiple linear regression analysis showed that the scientific research ability of undergraduate nursing interns was influenced by the research time, annual family incomes and the professional identity which explained 71.6% of the total variance. Mediating effect test indicated an indirect effect of achievement motivation on scientific research ability of nursing undergraduates by completely taking professional identity as an intermediary variable.Conclusions:Undergraduate nursing interns have a low to moderate level of scientific research ability. Professional identity has a complete mediating effect in the effect of achievement motivation on scientific research ability which points out that hospitals and universities should take measures to improve the achievement motivation and professional identity of undergraduate nursing interns so as to promote the improvement of their scientific research abilities.

Objective To analyze the effects of glucocorticoid stent implantation combined with nasal endoscopic surgery on nasal ventilation function and serum levels of eosinophil cationic protein(ECP),fibronectin(Fn)and aquaporin-1(AQP-1)in patients with chronic sinusitis with nasal polyp(CSwNP).Methods 60 patients with CSwNP from January 2022 to February 2023 were included in the study,and then they were divided into experimental group and control group,with 30 cases in each,using random number table method.The experimental group was treated with glucocorticoid stent implantation based on the original nasal endoscopic surgery,and the control group was treated with nasal endoscopic surgery,and both groups were treated until 12 weeks after surgery.The two groups of nasal symptoms,quality of life,nasal structure and ventilation function,serum levels of ECP,Fn,AQP-1,and adverse reactions were compared.Results Compared before the treatment,scores of nasal mucosal structure(Lund-Mackay scale),nasal symptom visual analogue scale(VAS)(including:nasal obstruction,runny nose,stuffy head,decreased sense of smell,nasal dryness/scab)and serum levels of ECP were decreased,distance from minimum nasal cross section to anterior nostril(DCAN)was shortened in two groups 12 weeks after treatment,and the experimental group was lower than the control group,the differences were statistically significant(P<0.05).Compared before the treatment,12 weeks after treatment,the nasal minimum cross-sectional area(NMCA),score of world health organization abbreviated quality of life(WHOQOL-100),nasal cavity volume(NCV),serum levels of Fn,AQP-1 were increased in two groups,and the experimental group was higher than the control group,the differences were statistically significant(P<0.05).During treatment,the incidence of adverse reactions was similar between the two groups(P>0.05).Conclusion Glucocorticoid stent implantation combined with nasal endoscopic surgery can control nasal symptoms in patients with CSwNP,improve nasal structure and ventilation function,regulate serum levels of ECP,Fn,AQP-1,and improve patients'quality of life.

ObjectiveTo analyze the epidemiological characteristics of senile dementia death in Jing’an District from 2016 to 2020， as well as the trends of mortality， standardized mortality， years of life lost （YLL） due to early death， years lived with disability （YLD）， and disability-adjusted life year （DALY）， and to provide scientific basis for the prevention and control of senile dementia. MethodsThe distribution of senile dementia in terms of gender， age， marital status and education level was investigated in the senile dementia death cases from 2016 to 2020 in Jing’an District. The YLL， YLD， DALY and their rates of the residents of Jing’an District from 2016 to 2020 were calculated by using Global Burden of Disease （GBD 2019） research method and results in combination with the corresponding population data. ResultsCompared to those without dementia， deaths with dementia were more likely to be female， more likely to be over 80 years old， less likely to be married， and more likely to have education level under middle school. Among the deaths with dementia， only 27.70% of the primary cause of death was dementia， and the other main causes were cerebrovascular disease， coronary heart disease and diabetes mellitus， which accounted for 25.54%， 17.81% and 7.28%， respectively. There was a significant gender difference in the burden of disease on senile dementia in Jing’an District. Mortality， standardized mortality， YLL， YLD and DALY rates of females were higher than those of males. The burden of disease on senile dementia increased with age. The change trend of mortality and YLL rate from 2016 to 2020 was not statistically significant， while the YLD rate and DALY rate showed an upward trend， which was statistically significant. ConclusionAs the life span of residents in Jing’an District increases and the population aging deepens， the burden of disease on senile dementia is still heavy. This requires extensive attention of the whole society， and active exploration of prevention and control strategies and measures for senile dementia， so as to improve the life quality of patients and reduce the burden of disease.

Background Diabetes mellitus is a major public health issue at present. Previous studies have shown that ambient air pollution is a risk factor for diabetes. Objective This study aims to explore the acute effects of ambient air pollution on diabetes related death in Shanghai Jing’an District. Methods Daily air pollution data, meteorological data, and diabetes related mortality data in 2013−2019 in Shanghai Jing’an District were collected. A generalized additive model (GAM) was established to conduct time-series analysis on the short-term effect of ambient air pollution on diabetes related mortality, and gender- and age-stratified analysis on susceptibility of various groups to ambient air pollution exposures. Results For every 10 μg·m⁻³ increase of the concentrations of PM_2.5, PM₁₀, SO₂, and NO₂, the diabetes related mortality increased by 2.47% (95%CI: 1.56%−3.38%), 2.02% (95%CI: 1.29%−2.75%), 5.75% (95%CI: 2.99%−8.58%), and 3.93% (95%CI: 2.49%−5.39%) at lag05 respectively (P<0.05). In the stratified analysis, exposures to increased concentrations of PM_2.5, PM₁₀, SO₂, and NO₂ raised the mortality risks from diabetes in male, female, and ≥65 years oldgroups (P<0.05). However, the differences in mortality risks from diabetes due to air pollution within gender and age groups were statistically insignificant. Conclusion In Shanghai Jing'an District, the elevated levels of ambient air pollutants, including PM_2.5, PM₁₀, SO₂, and NO₂, are significantly associated with the increase of diabetes related mortality, and there are lag effects and cumulative effects. The ≥65 years olds are more susceptible to the impact of air pollution on diabetes related deaths.
