In addition, the awareness of schistosomiasis control knowledge increased from 54.3% to 82.7% (χ2 = 188.886, P < 0.01), and the correct rate of attitudes towards schistosomiasis control increased from 88.4% to 98.0% (χ2 = 22.001, P < 0.01), while the correct rate of healthy behaviors increased from 48.2% to 59.7% (χ2 = 11.767, P < 0.01). Conclusions The whole-process health education model may remarkably improve the awareness of schistosomiasis control knowledge and promote the formation of positive attitudes towards schistosomiasis control and correct behaviors among inpatients with ascites type of advanced schistosomiasis, which is of great significance to facilitate patients’ cure.

Clinical application progress of platelet-rich plasma in facial aesthetics / 中国输血杂志

Platelet-rich plasma (PRP) is a kind of autologous blood product. It is a platelet concentrate extracted from autologous blood through centrifugation or apheresis process. It is generally believed that the platelet concentration in PRP should be 4-8 times of the platelet count in the whole blood. Platelets with high concentration can release a variety of growth factors and media after activation, which is conducive to tissue repair and regeneration. PRP has been used in regenerative medicine for more than 30 years, and has achieved good results. In recent years, it has also been widely used in facial aesthetics, involving acne, skin aging, hair loss, chloasma and other fields. In this review, we are not only emphasized the preparation and use of PRP, but also outlined the application progress of PRP in facial aesthetics.

Panic state and related influencing factors among military personnel during coronavirus disease 2019 outbreak / 第二军医大学学报

Objective To explore the panic state and related influencing factors among military personnel during the early epidemic stage of coronavirus disease 2019 (COVID-19). Methods In the early stage of the COVID-19 epidemic, 431 officers and soldiers stationed in Hebei were randomly selected by the cluster sampling method and investigated with psychological stress self-evaluation test (PSET), self-rating anxiety scale, and self-designed questionnaires regarding the knowledge of COVID-19, sources of psychological panic scale, evaluation scale of various information released and risk perception scale. Results A total of 411 valid questionnaires were collected, with an effective rate of 95.36%. The results showed that 5.84% (24/411) of the officers and soldiers were in psychological stress state and 4.14% (17/411) in psychological panic state. The psychological panic score of officers and soldiers in psychological stress state (47.76±6.51) was significantly higher than that in non-stress state (32.95±10.94), and the difference was statistically significant (t＝106.01, P0.01). There were significant differences in their understanding of different dimensions of COVID-19 knowledge (χ2＝91.53, P0.01). The high proportions of lack of understanding were found for COVID-19 related research progress (22.87%, 94/411) and symptoms (20.92%, 86/411). The main sources of psychological panic were the highly infectious trait of the virus, all wearing masks and eye glasses, information from the Internet and so on. Among all kinds of released information, the numbers of cumulative confirmed cases, new confirmed cases and cumulative suspected cases were the concerned epidemic information. The age, degree of anxiety in risk perception, possibility of infection, level of psychological stress and knowledge regarding COVID-19 were the predictors of psychological panic among military personnel (P0.05 or P0.01). Among the dimensions of risk perception, the predictors for apprehension regarding COVID-19 among military personnel included the influence of COVID-19 on individuals and society and event characteristics of COVID-19 (P0.05 or P0.01). For the interventions of panic state, providing relevant medical knowledge was the most needed. Conclusion During the early stage of COVID-19 epidemic, factors such as risk perception and the sources of psychological panic can affect the psychological panic among military personnel. During the CVOID-19 epidemic, corresponding measures should be taken to prevent the psychological panic among the officers and soldiers.

Progress of schistosomiasis control in Dongting Lake regions / 中国血吸虫病防治杂志

As an ancient parasitic disease, schistosomiasis has been endemic in Dongting Lake areas for more than 2 100 years. In the early 20th century, the first human case of schistosomiasis in China was reported in Dongting Lake areas, which was paid extensive attention. After the founding of the People’s Republic of China, large-scale schistosomiasis control activities were launched promptly in Dongting Lake areas, and great successes have been achieved following the three stages of control efforts, including the snail control-based stage, synchronous chemotherapy for humans and livestock-based control stage and infectious source control-based control stage. In 2015, transmission control of schistosomiasis was achieved in Hunan Province. This paper comprehensively describes the discovery and control of schistosomiasis, analyzes the challenges for the current schistosomiasis control programs and proposes the emphasis for future control activities in Dongting Lake areas, so as to provide insights into the schistosomiasis control program in this area.

Objective To predict the changes in the prevalence of Schistosoma japonicum infections in humans and livestock in Hunan Province using the exponential smoothing model and the ARIMA model. Methods The data pertaining to S. japonicum infections in humans and livestock in Hunan Province from 1957 to 2015 were collected, and the exponential smoothing model and the ARIMA model were created using the software Eviews and PASW Statistics 18.0. In addition, the effectiveness of these two models for the prediction of S. japonicum infections in humans and livestock in Hunan Province from 2016 to 2018 was evaluated. Results The exponential smoothing model and the ARIMA model had a high goodness of fit for prediction of S. japonicum infections in humans and livestock in Hunan Province from 1957 to 2015. There was a linear trend in the prevalence of S. japonicum infections in humans and livestock in Hunan Province from 1957 to 2015. The prevalence of S. japonicum infections in humans predicted with the Brown’s linear trend and the prevalence of S. japonicum infections in livestock predicted with the Holt’s linear trend in Hunan Province from 2016 to 2018 fitted better the actual data than the ARIMA model; however, prediction of the ARIMA model indicated that the endemic situation of schistosomiasis remained at a low level in Hunan Province. Conclusion At a low epidemic level, development of highly sensitive tools for monitoring schistosomiasis is urgently needed in Hunan Province to fit the current endemic situation, and the schistosomiasis control measures should be intensified to consolidate the control achievements.

iTRAQ-based quantitative proteomics of cultivated Pseudostellaria heterophylla and its wild type / 药学学报

This work was designed to investigate proteins differentially expressed in cultivated Pseudostellaria heterophylla and its wild type using iTRAQ proteomics approach. The extracted proteins were digested using FASP method and identified by iTRAQ coupled with LC-MS/MS technology and then analyzed by Protein Pilot 5.0 search engine. Proteins differentially expressed were searched through comparison of relatively quantified proteins. The analysis was conducted using GO (gene ontology), KEGG and STRING. A total of 3 775 proteins were detected, among them, 3 676 proteins can be quantified, of which 127 proteins were up-regulated and 205 were down-regulated in cultivated Pseudostellaria heterophylla. We found 71 significantly differentially expressed proteins for further analysis. These proteins were classified into nine categories:heat shock proteins, transferases, oxidoreductases, lyases, isomerases, ligases, hydrolases, tubulin and translocases. The results indicated that the carbohydrate and cellular amino acids metabolism of cultivated Pseudostellaria heterophylla were weaker than its wild type and its ability of responding to stress was much stronger. GWD1, PHS1, GBE1, PGM, and BAM1 are the important proteins to regulate sucrose; metE and CYS are the key proteins that regulate amino acids in cultivated and wild Pseudostellaria heterophylla. This will provide the basic information for exploring the cause of secondary metabolites differences in different ecotype of Pseudostellaria heterophylla and the protein mechanism of its quality formation.
