Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ²＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P <0.001). Obese people had the highest detection rate of hyperuricemia (66.95%), followed by overweight people (43.75%), and the difference was statistically significant (P <0.001). Multivariate logistic analysis showed that alcohol drinking (OR=1.836, 95% CI=1.139-2.961, P =0.013) and body mass index ≥ 24 kg/m² (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

Objective In order to determine the incidence and mortality of uterine body cancer in Gansu province in 2019,the epidemic characteristics and the change trend of incidence and death from 2010 to 2019 were analyzed.Methods The quality control qualified data in Gansu province tumor registration center were used,uterine body cancer in urban and rural,age-specific inci-dence(mortality),the China standardized rate by Chinese population,the World standardized rate by World population,cumulative rate,crude incidence(mortality),composition ratio and rank,average annual percentage change(AAPC)and other indicators were calculated.Results In 2019,uterine body cancer in Gansu province ranked the seventh in the incidence of female malignant tumors,with a crude incidence of 4.43/100,000,the China standardized incidence was 3.28/100,000,and the World standardized incidence was 3.19/100,000.In 2019,uterine body cancer in Gansu province ranked the sixth among the mortality of female malignant tumors,with the crude mortality of 0.56/100,000,the China standardized mortality was 0.36/100,000,and the World standardized mortality was 0.35/100,000.The peak of morbidity(mortality)was in the age range of 50 to 54 years old.From 2010 to 2019,the incidence of uterine body cancer in Gansu province showed an overall upward trend.The China standardized incidence was AAPC=4.34%(95%CI:1.60%-7.15%),with a statistically significant trend(P<0.05);The mortality of uterine body cancer showed a fluctuating pat-tern of first rising,then decreasing,and increasing again,showing an overall downward trend.The China standardized mortality was AAPC=-11.35%(95%CI:-26.77%-7.32%),and the trend was not statistically significant(P>0.05).The incidence(mortali-ty)in rural areas was higher than that in urban areas.Conclusion The overall incidence of uterine body cancer in Gansu province is on the rise,and the death is on the decline.However,mortality in rural areas is on the rise.It is recommended to vigorously promote women′s health science popularization and education throughout the province,strictly implement the comprehensive measures of"early detection,early diagnosis,early treatment",and focus on the prevention and control of women aged 50-54,especially strengthening the early diagnosis and treatment of uterine body cancer in rural areas.

Objective To establish human and mouse pancreatic cancer cell strains stably expressing Cas9 protein,green fluorescent protein,red fluorescent proteins,luciferase-tdTomato,and to validate the activity of luciferase and gene editing of Cas9 function for pancreatic cancer research using luciferase and CRISPR/Cas9 system.Methods In human pancreatic cancer cells(AsPC-1,CFPAC-1,HPAC,BxPC-3,HS 766T,MIA PaCa-2,PANC-1,and SW 1990),and mouse pancreatic cancer cell(Pan02),the cells were infected with Cas9-expressing plas-mid pLv-EF1α-Cas9m1.1-Puro,and single-cell clones were selected for culture and expansion.After extracting the total protein,Western blot verified the expression level of Cas9;Infected with fluorescent protein expression plasmids pLv-EF1α-EGFP,pLv-EF1α-mCherry,pLv-EF1α-tdTomato,pLv-EF1α-Luc2-tdT,and selected single cell clones stably expressing fluorescent proteins were cultured and amplified under fluorescence microscope.Cas9 stable expression cell line was selected to be infected with pLv-EF1α-Luc2-tdT,and the mono-clonal culture of stable expression of fluorescent proteins was selected for expansion under fluorescence micro-scope.One of the cell lines were selected to be infected with Lv-EF1a-mCherry,and the mCherry-positive cells were sorted out by flow cytometry,and then the guide RNA of mCherry gene was then infected by lentivirus to tar-get the mCherry gene,and after cell expansion,mCherry knockdown was detected by fluorescence microscope observation and flow cytometry;5 BALB/c Nude mice were subcutaneously inoculated with MIA PaCa-2-Luc2-tdT cells(1.0×107/cells each),and imaged in vivo after 36 days.Results 48 human pancreatic cancer cell strains with stable Cas9 expression were screened(including 23 cells expressing Cas9m1.1,25 cells expressing Cas9m1.1-Luc2-tdT),33 pancreatic cancer cell strains with stable expression of fluorescent proteins were screened(8 cells expressing EGFP,7 expressing mCherry,and 9 each expressing Luc2-tdT and tdTomato).Cells expressing mCherry and Cas9 were infected with mCherry gRNA and mCherry was knocked down.In vivo imaging showed that both bioluminescence and fluorescence luminescence were present in MIA PaCa-2 cells ex-pressing Luc2-tdT.Conclusions 33 pancreatic cancer cell strains with stable expression of fluorescent proteins are successfully established,in which the Luc2-tdT-expressing cell strains have luciferase activity;48 pancreatic cancer cell strains with stable expression of Cas9 are successfully established,and the Cas9 protein has gene edi-ting activity,gene editing activity varies depending on the original cell strains.

Objective:To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors.Methods:This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects′ music listening was investigated using SPSS 25.0 statistical software.Results:All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors ( P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors ( P value>0.05). Conclusions:Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.
