Abstract：Objective To investigate the morphological features of the Pneumocystis jirovecii, in order to facilitate early detection and rapid diagnosis of this rare pathogen from a morphology point of view by laboratory technicians. By analyzing the laboratory features and application value of different pathogen detection methods in the diagnosis of Pneumocystis jirovecii pneumonia, we aim to provide the most reliable diagnostic basis for rapid diagnosis of Pneumocystis jirovecii pneumonia.Methods A retrospective analysis was conducted on the test results of bronchoalveolar lavage fluid samples from a comprehensive hospital in Zhangqiu District, Jinan City, Shandong Province, and a hospital in Changde City from April 2022 to October 2022. Five confirmed cases of Pneumocystis jirovecii pneumonia were detected. Its clinical manifestations, laboratory results, and morphological characteristics of pathogens under different stains were analyzed to discuss the advantages and disadvantages of different detection methods. Results Cytological examination of bronchoalveolar lavage fluid found the trophozoites and cysts of Pneumocystis jirovecii by Wright's-Giemsa staining in 4 cases (80%), and the cysts of Pneumocystis jirovecii by Silver hexamine staining in 4 cases (80%), while the metagenomic next-generation sequencing confirmed all the 5 positive results. All 5 patients had different degrees of reduction in the absolute count of peripheral blood lymphocytes, and the serum lactic dehydrogenase and (1-3)-β-D-Glucan were increased. Among the 5 patients in this study, 4 were treated with sulfamethoxazole combined with caspofungin, and 1 was treated with sulfamethoxazole. Three patients were cured and discharged from hospital after treatment, but two died. Conclusions The method of Wright's-Giemsa staining for the cytological examination of bronchoalveolar lavage fluid to find Pneumocystis jirovecii has the unique and irreplaceable advantages as silver staining. Metagenomic next-generation sequencing can further increase the positive detection rate of Pneumocystis jirovecii. The combination of cytological examination of bronchoalveolar lavage fluid with metagenomic nextgeneration sequencing is a powerful diagnostic method for rapid diagnosis of Pneumocystis jirovecii pneumonia, which can diagnose accurately and reduce missed diagnosis.

Objectives To investigate the effects of low level of ambient NO₂ on the death of cardiovascular and cerebrovascular diseases in Enshi city and to identify sensitive population, so as to provide a scientific basis for formulating health policies. Methods The data of air pollutants, meteorological factors and death of cardiovascular and cerebrovascular diseases in Enshi city from 2015 to 2018 were collected. The generalized additive model based on Poisson distribution was used to analyze the effects of low ambient NO₂ level on the death risk of cardiovascular and cerebrovascular diseases in Enshi city. A subgroup analysis was performed on age, gender, and season. Results The average concentrations of major gaseous air pollutants in Enshi city from 2015 to 2018 were NO₂ (21.40 μg/m³), SO₂ (9.68 μg/m³), CO (0.88 mg/m³), and O₃ (61.21 μg/m³), respectively, all of which did not exceed the national secondary standard. The results of single pollutant model analysis showed that each 1 μg/m3 increase in NO₂ concentration in lag0 day was associated with a 0.33% increase (95% CI: 0.06 - 0.72) (P>0.05) in mortality risk of cardiovascular and cerebrovascular diseases. In the female population, each 1 μg/m3 increase in NO2 concentration in lag01 day was associated with a 0.92% increase (95% CI: 0.26 - 1.56) (P<0.05) in mortality risk of cardiovascular and cerebrovascular diseases. In the cold season, each 1 μg/m3 increase in NO₂ concentration in lag0 day was associated with a 0.62% increase (95% CI: 0.12 - 1.12) (P<0.05) in mortality risk of cardiovascular and cerebrovascular diseases. The results of the two-pollutant model showed that after controlling other gaseous pollutants (SO₂, CO or O₃), the effect of NO₂ on the mortality risk of cardiovascular and cerebrovascular diseases in women and the whole population in cold season still existed. Conclusion The low ambient level of NO₂ in Enshi city was significantly associated with increased mortality risk of cardiovascular and cerebrovascular diseases in female population as well as in cold seasons in the whole population. Attention should be paid to the health protection of special populations in areas with low ambient pollution level of NO₂ in special seasons.

Objective To analyze the basic characteristics and variation trend of death causes of permanent residents in Enshi City during 2013-2018, to assess the burden of different diseases, and to provide a scientific basis for formulating disease prevention and control strategies. Methods The death monitoring data of permanent residents in Enshi City, Hubei Province from 2013 to 2018 was collected. The crude mortality, standardized mortality, life expectancy, potential years of life loss (PYLL), standard potential years of life loss (SPYLL), average years of life lost (AYLL), and annual percentage change (APC) were calculated to describe the distribution and trend of death causes. Results The average annual crude death rate and standardized death rate of residents in Enshi City from 2013 to 2018 were 679.43 per 100 000 and 615.02 per 100 000, respectively. The top 5 causes of death were circulatory system diseases, respiratory system diseases, malignant tumors, injuries, and digestive system diseases, accounting for 91.2% of the total deaths. Analysis of life expectancy found that the average life expectancy of local residents from 2013 to 2018 was 78.02 years, and the value in the male group (75.57 years) was lower than that in the female group (80.78 years). Life loss analysis revealed that PYLL caused by various diseases was 171 620 person-years, SPYLL was 171 284.62 person-years, and AYLL was 15.03 years/person in Enshi City from 2013 to 2018. Among all the death causes, the top five in terms of life loss were injuries, malignant tumors, circulatory diseases, respiratory diseases and digestive diseases. Conclusion From 2013 to 2018, the death rate of residents in Enshi City was relatively higher compared with those in other cities in China, the average annual crude death rate was on the rise, and the average annual standardized death rate was on the decline, indicating a highly ageing region. Chronic diseases such as circulatory system diseases, malignant tumors, and respiratory diseases, as well as injuries were the main death causes and caused a heavy burden of diseases, which should be the focus of future prevention and control work. Considering the higher levels of death and life loss indicators of male residents than those of women, targeted prevention and control measures should be taken to narrow the gap between men and women and improve the overall life quality of the whole population.

Objective:To rapidly evaluate the level of healthcare resource demand for laboratory testing and prevention and control of corona virus disease 2019 (COVID-19) in different epidemic situation, and prepare for the capacity planning, stockpile distribution, and funding raising for infectious disease epidemic response.Methods:An susceptible, exposed, infectious, removed infectious disease dynamics model with confirmed asymptomatic infection cases and symptomatic hospitalized patients was introduced to simulate different COVID-19 epidemic situation and predict the numbers of hospitalized or isolated patients, and based on the current COVID-19 prevention and control measures in China, the demands of resources for laboratory testing and prevention and control of COVID-19 were evaluated.Results:When community or local transmission or outbreaks occur and total population nucleic acid testing is implemented, the need for human resources is 3.3-89.1 times higher than the reserved, and the current resources of medical personal protective equipment and instruments can meet the need. The surge in asymptomatic infections can also increase the human resource demand for laboratory testing and pose challenge to the prevention and control of the disease. When vaccine protection coverage reach ≥50%, appropriate adjustment of the prevention and control measures can reduce the need for laboratory and human resources.Conclusions:There is a great need in our country to reserve the human resources for laboratory testing and disease prevention and control for the response of the possible epidemic of COVID-19. Challenges to human resources resulted from total population nucleic acid testing and its necessity need to be considered. Conducting non-pharmaceutical interventions and encouraging more people to be vaccinated can mitigate the shock on healthcare resource demand in COVID-19 prevention and control.
