Objective To understand the concentration of cement dust in nonmetallic mineral products industry in Guilin City,provide basis for the prevention of cement pneumoconiosis. Methods A total of 29 enterprises that produce cement dust in the non-metallic mineral products industry in Guilin City were randomly investigated. The places and positions that produce cement dust in the non-metallic mineral products industry in Guilin City were identified through the field investigation of occupational health,andon-site sampling and testing were conducted according to the national occupational health standards. Results In 2020,there were 29 enterprises with cement dust in the non-metallic mineral products industry in Guilin City. The content of free silica in dust of small enterprises was 0.79%-7.85%,and that of micro-enterprises was 1.47%-5.96%.The exceedance rates of total dust and respirable dust concentration in workplaces of small enterprises were 46.51% and 51.16%,respectively. The exceedance rate of total dust and respirable dust concentration in the workplace of micro enterprises were 29.73% and 29.73%,respectively.The exceedance rates of total dust and respirable dust concentration in positions of small enterprises were 31.67% and 53.33%,respectively. The exceedance rates of total dust and respirable dust concentration in positions of micro enterprises were 12.50% and 32.50%,respectively. There were no statistically significant differences in the exceedance rates of total dust and respirable dust concentration in workplaces among different scale enterprises（χ²=2.36,3.77,both P>0.05）,there were statistically significant differences in the exceedance rates of total dust and respirable dust concentration in positions among different scale enterprises（χ²=4.83,4.21,both P<0.05）.In the four positions of cement dust working sites detecting dust concentration-time weighted average（C_TWA）,the exceedance rate of total dust C_TWA in batching operation point was the highest at 85.71%,and the exceedance rate of respirable dust C_TWA in batching operation point was the highest at 64.29%.There were statistically significant differences in the exceedance rates of total dust and respirable dust detection results among different working sites（χ²=20.22,7.83,both P<0.05）. In the four positions of cement dust working sites detecting C_TWA,the exceedance rate of total dust C_TWA in cement grinding operation point was the highest at 42.11%,and the exceedance rate of respirable dust C_TWA in batching operation point was the highest at 75.00%.There were no statistically significant differences in the exceedance rates of total dust and respirable dust detection results among different working sites（χ²=3.26,1.28,both P>0.05）. Conclusions The concentration of cement dust exceeds the standard in workplaces and posts of nonmetallic mineral products industry,which is easy to cause the occurrence of cement pneumoconiosis in workers to a certain extent. The relevant functional departments should strengthen the supervision of occupational health,strengthen the supervision and law enforcement of occupational health,further implement the employer's main responsibility system,and protect the physical and mental health of workers.

Objective To study the pulmonary toxic effect of fine particulate matter（PM_2.5） on rats of different gender by acute exposure to PM_2.5 by tracheal instillation. Methods SD rats of SPF grade were randomly divided into saline control group,PM_2.5 high,medium and low dose（PM_2.5 powder dry weight of 13.5,4.5,1.5 mg/kg） groups. After tracheal instillation for seven days,dissected and calculated the lung organ coefficient. The changes of malondialdehyde（MDA）,superoxide dismutase（SOD）,total protein（TP） and albumin（ALB） were detected, and hematoxylin and eosin（HE） staining were used to observe the pathological changes of lung tissue. Results The coefficien to flung organs in each group increased with the increase of exposure dose,and the differences between the high-dose group of female mice[（0.758±0.263）%] and the control group[（0.530±0.026）%],the low-dose group of male mice[（0.476±0.049）%] and the female mice[（0.565±0.057）%] were statistically significant（both P<0.05）.Compared with the control group,the MDA content of female mice increased with the increase of PM_2.5 dose（P<0.05）. There was a statistically significant difference in MDA content between female mice in the high-dose group[（1.159±0.162）nmol/mgprot] and male mice[（0.865±0.155）nmol/mgprot]（P<0.05）. The TP content of male mice in the medium and high dose groups[（0.264±0.069）,（0.396±0.124）g/L] was lower than that of female mice at the same dose[（0.508±0.219）,（0.812±0.140）g/L]（both P<0.05）. The ALB content in the middle dose group[（1.009±0.970）g/L] and high dose group[（1.479±0.874）g/L] of female mice increased compared to the same sex control group[（0.219±0.141）g/L]（P<0.05）,while the ALB content in the high dose group of male mice[（0.840±0.278）g/L] increased compared to the same sex control group[（0.253±0.185）g/L]（P<0.01）. HE staining showed that with the increase of exposure dose,the alveolar wall of rats gradually thickened,and large areas of alveolar consolidation appeared in the medium and high dose groups,with female mice having more severe lesions than male mice. Conclusion Acute exposure to PM_2.5 can cause oxidative stress damage to rat lung tissue,damage alveolar epithelium,and change pulmonary capillary permeability,with gender differences in this type of damage.

Objective To study the effect and mechanism of zinc intervention on the learning ability of APP/PS1 transgenic mice with prenatal chronic stress and offspring chronic stress. Methods After prenatal chronic stress,32 APP/PS1 transgenic male rats were selected from their offspring. After normal feeding to the age of six months,they were randomly divided into four groups：high,medium and low dose groups（30.34,15.18,6.1 mg/kg） and blank control group,eight rats in each group.From the age of six months,they were subjected to chronic stress for three months and zinc intervention was added at the same time. After the stress treatment,the Morris water maze test was used to test learning and memory ability,pathology of hippocampal CA3 region of mice was observed by hematoxylin eosin（HE） staining,Aβ_1-40 and Aβ_1-42 in hippocampus were detected by ELISA,and the expression level of BACE1 in hippocampus were detected by Western blot. Results Morris water maze：compared with the blank control group,the incubation period of zinc intervention group was shorter,and the number of crossing platforms was more（all P<0.01）.HE staining：the structure of hippocampal CA3 area in the blank control group was disordered,the cells were necrotic and loose,and the number of nerve cells in the zinc intervention group was large,the state was good,and the structure was clear.ELISA experiment and Western blot experiment：compared with the control group,the expression levels of Aβ_1-40,Aβ_1-42 and BACE1 in all dose groups decreased（all P<0.05）. Conclusion The supplement of certain zinc can reduce the expression levels of Aβ_1-40,Aβ_1-42 in hippocampus by decreasing the production of BACE1,so as to improve the damage of hippocampus and learning and memory ability of APP/PS1 transgenic mice caused by prenatal chronic stress combined with offspring chronic stress.

Objective To explore the mediating role of perceived ageism between alienation and expectation regarding aging of rural seniors,provide specific countermeasures for maintaining the mental health of rural seniors,and provide a reference basis for further promoting healthy aging. Methods By using the method of convenient sampling,437 seniors from six villages in Hunan Province were selected as the subjects of the survey from July to September 2021. The investigation was performed by the perceived ageism questionnaire,alienation scale and aging expectation scale. Results The total score[M（P₂₅,P₇₅）] of the aging expectation of the rural elderly was [67.00（61.00,74.00）]points,the total score of perceived ageism was [1.00（1.00,4.00）] points,and the total score of alienation was （33.29±10.44）points. The perceived ageismand alienation were negatively correlated with aging expectation（r=-0.303,-0.477,both P<0.01）,and perceived ageism was positively correlated with alienation（r=0.425,P<0.01）. The perceived ageism partially mediated the alienation and aging expectation of the rural elderly,and the indirect effect accounted for 18.25% of the total effect. Conclusions The level of expectation regarding aging of rural seniors is in the middle level,alienation and perceived ageism are important influencing factors of expectation regarding aging,and perceived ageism plays an intermediary role in the influence of alienation on expectation regarding aging. Therefore,the state should promote a series of anti-discrimination measures,the society should also increase the publicity of respecting and loving the elderly,and the government should regularly screen the alienated seniors groups to ensure the mental health of seniors.The rural grass-roots workers should guide the formation of social interaction among seniors to achieve the meaning of life,and the rural seniors should actively cultivate their enthusiasm to participate in social practice and face age discrimination with a positive attitude. With the joint efforts of many aspects,it is achievable to raise the expectation regarding aging level of seniors and promote healthy aging.

Objective To analyze the monitoring results of routine immunization coverage rate in Beihai City in 2021,evaluate the monitoring quality of reported vaccination rates in Beihai City and analyze the reasons. Methods The estimated vaccination rate,difference（D）,ratio（R） and deletion rate were used to evaluate and analyze the routine immunization data of Beihai City in 2021. Results In 2021,the complete rate of routine immunization reports in Beihai City was 100%. The reported vaccination rates of basic immunization for HepB,OPV,DTP,MMR,MenA,JE and HepA in Beihai City ranged from 99.02% to 99.43%,and the estimated vaccination rates ranged from 91.31% to 111.62%. The reported vaccination rates of booster immunizations for DTP4,MMR2,JE2,OPV4,DT,MenA+C1-2 ranged from 97.92% to 99.42%,and the estimated vaccination rates ranged from 48.32% to 92.10%. D-value of HepB,DTP,MenA and JE in municipal basic immunity were evaluated as reliable（D≤5%）,while OPV,MMR and HepA were suspected（5%<D≤15%）. Enhanced immunity of DTP,MMR,JE,DT and MenA+C2 were suspected（5%<D≤15%）,while OPV and MenA+C1 were unreliable（D>15%）. City level R-value evaluation was reliable（0.95≤R≤1.05）. The leakage rate was reasonable for all vaccines except JE,which was evaluated as unreasonable. Conclusion The reported vaccination rate of routine immunization in Beihai City remains at a high level,but there may be problems of insufficient mapping and inflated vaccination rates,indicating that the quality of routine immunization monitoring work needs to be further improved.

Objective To systematically analyze the spatial and temporal variation characteristics of inhalable particle（PM₁₀）,fine particle（PM_2.5）,NO₂,SO₂,CO and O₃,provide scientific basis for the prevention and control of air pollutants in "Wuchangshi" area. Methods Based on data from national air quality monitoring sites in "Wuchangshi" area from 2016 to 2020,the spatial and temporal variation characteristics and correlation of six air pollutants were analyzed. Results As for spatial distribution patterns,obviously differences existed for six pollutants in "Wuchangshi" area from 2016 to 2020. Except SO₂ and O₃,the mean concentration of all pollutants was the highest in Urumqi. From 2016 to 2020,the annual mean concentrations of PM₁₀,PM_2.5,NO₂,CO and SO₂ decreased by 13.3%,9.3%,17.9%,25.9% and 45.2%,respectively. In contrast,the annual mean concentration of O₃ increased by 23.8%. The concentrations of PM₁₀,PM_2.5,NO₂,CO and SO₂ were more serious in winter,and the lowest in summer. The highest concentration of O₃ occurred in spring and summer,and the lowest in winter. The daily concentrations of PM₁₀,PM_2.5,CO and NO₂ presented double peaks distribution,the peak of PM₁₀ and PM_2.5 concentration occurred at 00：00-02：00 at night,while the daytime peaks occurred at 10：00-13：00 and 14：00-16：00,respectively. The peak of NO₂ and CO concentration occurred at 23：00-01：00 and 09：00-11：00,respectively. The peak of SO₂ and O₃ concentration occurred at 13：00-16：00 and 16：00-17：00,respectively. The concentrations of PM₁₀,PM_2.5,NO₂,SO₂ and CO in "Wuchangshi" area were significantly positively correlated with each other,while O₃ and the five pollutants were significantly negatively correlated. Conclusion Except O₃,the air pollution in "Wuchangshi" area has been improving year by year,but the pollution of PM₁₀ and PM_2.5 still exceeds the second-level concentration limit,so the emphasis should be placed on the coordinated prevention and control of O₃ and atmospheric particulate pollution in "Wuchangshi" area.
