Objective:
To analyze the epidemiological characteristics and influencing factors of severe fever with thrombocytopenia syndrome (SFTS) in Zhejiang Province from 2019 to 2023, so as to provide the reference for strengthening SFTS prevention and control.
Methods:
Data on laboratory-confirmed SFTS cases in Zhejiang Province from 2019 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System. Meteorological data, geographic environment and socioeconomic factors during the same period were collected from the fifth-generation European Centre for Medium-Range Weather Forecasts, Geospatial Data Cloud, and Zhejiang Statistical Yearbook, respectively. Descriptive epidemiological methods were used to analyze the epidemiological characteristics of SFTS from 2019 to 2023, and a Bayesian spatio-temporal model was constructed to analyze the influencing factors of SFTS incidence.
Results:
A total of 578 SFTS cases were reported in Zhejiang Province from 2019 to 2023, with an annual average incidence of 0.23/105. The peak period was from May to July, accounting for 52.60%. There were 309 males and 269 females, with a male-to-female ratio of 1.15∶1. The cases were mainly aged 50-<80 years, farmers, and in rural areas, accounting for 82.53%, 77.34%, and 75.43%, respectively. Taizhou City and Shaoxing City reported more SFTS cases, while Shaoxing City and Zhoushan City had higher annual average incidences of SFTS. The Bayesian spatio-temporal interaction model showed good goodness of fit. The results showed that mean temperature (RR=1.626, 95%CI: 1.111-2.378) and mean wind speed (RR=1.814, 95%CI: 1.321-2.492) were positively correlated with SFTS risk, while altitude (RR=0.432, 95%CI: 0.230-0.829) and population density (RR=0.443, 95%CI: 0.207-0.964) were negatively correlated with SFTS risk.
Conclusions
SFTS in Zhejiang Province peaks from May to July. Middle-aged and elderly people and farmers are high-risk populations. Taizhou City, Shaoxing City, and Zhoushan City are high-incidence areas. Mean temperature, mean wind speed, altitude, and population density can all affect the risk of SFTS incidence.

ObjectiveTo reveal the active substances and mechanisms of modified Qing'e formula (MQEF) in delaying skin photoaging by ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UPLC-Q-TOF-MS),network pharmacology, and cell experiments. MethodsUPLC-Q-TOF-MS and a literature review were employed to analyze the transdermally absorbed components in mice after the topical application of MQEF. The potential targets of MQEF in treating skin photoaging were retrieved from databases.The compound-potential target network and protein-protein interaction network were constructed to screen the key components and core targets. A photoaging cell model was established by irradiating HaCaT cells with medium-wave ultraviolet B (UVB). The safe doses of bakuchiol (BAK) and salvianolic acid B (SAB) for treating HaCaT cells and the effects of BAK and SAB on the viability of cells exposed to UVB irradiation were determined by the cell counting kit-8 (CCK-8) method.The reactive oxygen species (ROS) fluorescent probe was used to measure the ROS production in the cells treated with BAK and SAB.The expression levels of genes related to oxidative stress,inflammation,collagen metabolism,and circadian rhythm clock were measured by Real-time PCR. ResultsA total of 24 transdermally absorbed components of MQEF were identified,which acted on 367 potential targets,and 417 targets related to skin photoaging were screened out,among which 47 common targets were predicted as the targets of MQEF in treating skin photoaging. MQEF exerted the anti-photoaging effect via key components such as BAK and SAB,which acted on core proteins such as serine/threonine kinase 1 (Akt1) and mitogen-activated protein kinase 3 (MAPK3) and intervened in core pathways such as the tumor necrosis factor (TNF) and phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) signaling pathways.Compared with the model group,the administration of BAK and SAB increased the survival rate of HaCaT cells (P<0.01),down-regulated the mRNA levels of cyclooxygenase-2 (COX-2),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α),matrix metalloproteinase-1 (MMP-1),and matrix metalloproteinase-9 (MMP-9) (P<0.01),and up-regulated the mRNA levels of heme oxygenase-1 (HO-1) and NAD(P)H quinone dehydrogenase 1 (NQO-1) (P<0.05,P<0.01) in photoaged HaCaT cells.In addition,it eliminated excess ROS production induced by UVB and up-regulated the mRNA levels of brain and muscle ARNT-like 1 (BMAL1) and circadian locomotor output cycles kaput (CLOCK) associated with circadian clock (P<0.05,P<0.01). ConclusionMQEF delays skin photoaging through the coordinated effects of various components,multiple targets,and diverse pathways.The key components BAK and SAB in MQEF exhibit anti-photoaging properties,which involve inhibiting oxidative stress,preventing collagen degradation,mitigating inflammation,and maintaining normal skin circadian rhythms by regulating clock gene expression.

Objective:To develop a method of employing flow cytometry to directly detect the γ-H2AX expression levels in peripheral blood lymphocytes of mice through fixation and lysis and to evaluate the feasibility of applying this method to research on the radiation-related biological effects and the efficacy evaluation of radioprotective drugs.Methods:A total of 41 male C57BL/6J mice were used. First, 21 mice were randomly divided into 7 groups according to different radiation doses (0, 1, 2, 4, 6, 8, and 10 Gy) with 3 mice in each group. Blood samples were collected from the tail vein of mice at 1, 4, 8, and 24 h after irradiation and immediately fixed with formaldehyde. Red blood cells (RBC) were lysed with Triton X-100, and γ-H2AX was labeled with specific antibodies. DRAQ5 dye was used to further exclude debris and anucleate cells. The mean fluorescence intensity of γ-H2AX in lymphocyte populations was directly analyzed by flow cytometry through forward and side scatter, and dose-effect curves after irradiation were established. Then, the other 20 mice were divided into radiation alone groups and radiation combined with WR-2721 administration groups at 4 and 6 Gy, respectively, with 5 mice in each group. Blood samples were collected from the tail vein of mice at 1, 4, 8, and 24 h after irradiation to detect the average fluorescence intensity of γ-H2AX in lymphocytes, which was used to evaluate the degree of DNA damage in mice and the therapeutic effect of WR-2721.Results:The expression of γ-H2AX in peripheral blood lymphocytes of mice significantly increased with the increase of radiation doses, and reached a peak at 1-2 h and then decreased. The dose-effect relationship was significant ( R2 = 0.9914). At 24 h after 4 and 6 Gy irradiation, compared with the radiation alone groups, the average fluorescence intensity of γ-H2AX in the radiation combined with WR-2721 administration groups was lower (144.8 ± 8.0 and 109.5 ± 9.7, vs. 178.0 ± 18.5 and 136.6 ± 5.4), with statistically significant difference ( t = 3.78, 5.48, P < 0.05). The average fluorescence intensity of γ-H2AX at 24 h after irradiation was consistent with the lowest values of the three blood cell lines at 7 or 14 d after irradiation. Conclusions:The application of flow cytometry with a fixation/dissolution protocol to directly detect the mean fluorescence intensity of γ-H2AX in peripheral blood lymphocytes of mice has significant application value in radiation biology effect research, radiation protection drug screening, and efficacy evaluation.
