Objective To assess the situation and influencing factors of occupational burnout among the staff at the Center for Disease Control and Prevention (CDC) in Sichuan Province. Methods A total of 1 038 CDC staff members in Sichuan Province were selected as the study subjects using the stratified random sampling method. Occupational burnout of the staff was assessed using the Maslach Burnout Inventory General Survey via an online questionnaire. Results The detection rate of occupational burnout was 42.3% (439/1 038). Binary logistic regression analysis result showed that, after controlling for confounding factors such as education level and alcohol consumption, CDC staffs aged at 20-<31, 31-<41, and 41-<51 years were at higher risk of occupational burnout compared with those ≥51 years (all P<0.05). CDC staffs with 5-<10 or ≥10 years of service had higher occupational burnout risk compared with those with <5 years (both P<0.05). CDC staffs with poor or fair health status, irregular diet, and poor sleep quality had higher risk of occupational burnout compared with those healthy, have regular diet, and good sleep quality (all P<0.05). The risk of occupational burnout increased with higher overtime frequency (all P<0.05). Conclusion Occupational burnout among CDC staffs in Sichuan Province is relatively high. Age, years of service, health status, diet, sleep quality, and overtime frequency are key influencing factors.

To explore the variation laws of volatile oil during the extraction process of Artemisiae Argyi Folium and its impact on the quality of the medicinal solution, as well as to achieve precise control of the extraction process, this study employed headspace solid phase microextraction gas chromatography-mass spectrometry(HS-SPME-GC-MS) in combination with multiple light scattering techniques to conduct a comprehensive analysis, identification, and characterization of the changes in volatile components and the physical properties of the medicinal solution during the extraction process. A total of 82 volatile compounds were identified using the HS-SPME-GC-MS technique, including 21 alcohols, 15 alkenes, 14 ketones, 9 acids, 6 aldehydes, 5 phenols, 3 esters, and 9 other types of compounds. At different extraction time points(15, 30, 45, and 60 min), 71, 72, 64, and 44 compounds were identified in the medicinal solution, respectively. It was observed that the content of volatile components gradually decreased with the extension of extraction time. Through multivariate statistical analysis, four compounds with significant differences during different extraction time intervals were identified, namely 1,8-cineole, terpinen-4-ol, 3-octanone, and camphor. RESULTS:: from multiple light scattering techniques indicated that at 15 minutes of extraction, the transmittance of the medicinal solution was the lowest(25%), the particle size was the largest(0.325-0.350 nm), and the stability index(turbiscan stability index, TSI) was the highest(0-2.5). With the extension of extraction time, the light transmittance of the medicinal solution improved, stability was enhanced, and the particle size decreased. These laws of physicochemical property changes provide important basis for the control of Artemisiae Argyi Folium extraction process. In addition, the changes in the bioactivity of Artemisiae Argyi Folium extracts during the extraction process were investigated through mouse writhing tests and antimicrobial assays. The results indicated that the analgesic and antimicrobial effects of the medicinal solution were strongest at the 15-minute extracting point. In summary, the findings of this study demonstrate that the content of volatile oil in Artemisiae Argyi Folium extracts gradually decreases with the extension of extraction time, and the variation in volatile oil content directly influences the physicochemical properties and pharmacological efficacy of the medicinal solution. This discovery provides important scientific reference for the optimization of Artemisiae Argyi Folium extraction processes and the development and application of process analytical technologies.

Compounds isolated from Epimedium include the total flavonoids of Epimedium , icariin, and its metabolites (icaritin, icariside I, and icariside II), which have similar molecular structures. Modern pharmacological research and clinical practice have proved that Epimedium and its active components have a wide range of pharmacological effects, especially in improving sexual function, hormone regulation, anti-osteoporosis, immune function regulation, anti-oxidation, and anti-tumor activity. To date, we still need a comprehensive source of knowledge about the pharmacological effects of Epimedium and its bioactive compounds on the male reproductive system. However, their actions in other tissues have been reviewed in recent years. This review critically focuses on the Epimedium , its bioactive compounds, and the biochemical and molecular mechanisms that modulate vital pathways associated with the male reproductive system. Such intrinsic knowledge will significantly further studies on the Epimedium and its bioactive compounds that protect the male reproductive system and provide some guidances for clinical treatment of related male reproductive disorders.

OBJECTIVE:
To retrospectively analyze the clinical data of newly diagnosed acute myeloid leukemia (AML) patients treated with venetoclax combined with azacitidine (Ven/Aza) or standard "3+7" regimen and similar regimens, collect real-world study data, compare the treatment response and adverse events between the two regimens, as well as perform survival analysis.
METHODS:
To retrospectively analyze the efficacy, survival, and adverse reactions of newly diagnosed AML patients treated with Ven/Aza (24 cases) and "3+7" regimens (117 cases ) in our hospital from September 2009 to March 2023, as well as factors influencing outcomes. A propensity score matching (PSM) was performed on age and Eastern Cooperative Oncology Group performance status (ECOG PS) to obtain a 1:1 matched cohort of 20 pairs, and the efficacy and survival before and after the matching were compared.
RESULTS:
The median age of patients in the Ven/Aza group was 69 years, while that in the "3+7" group was 56 years (P <0.001). Objective remission rate (ORR) was 62.5% in Ven/Aza group and 74.8% in "3+7" group (P >0.05). The median overall survival (OS) in the Ven/Aza group was 522 days, while that in the "3+7" group was 1 002 days (P >0.05). After controlling the two variables of age and ECOG PS, a PSM cohort of 20 pairs was obtained, in which the ORR was 65% in Ven/Aza group and 60% in "3+7" group (P >0.05). The median OS was 522 days and 629 days, and median progression-free survival (PFS) was 531 days and 198 days between the two groups, respectively. There were no statistically significant differences in OS and PFS between the two groups (both P >0.05). Additionally, the incidence of adverse events in the Ven/Aza group was significantly reduced.
CONCLUSION
The overall cohort shows that the "3+7" regimen has advantages in efficacy and survival, but Ven/Aza regimen is relatively safer. After performing PSM on age and ECOG PS, the Ven/Aza group showed improved efficacy, and a longer median PFS compared to "3+7" group.

OBJECTIVE:
To assess the safety and topical efficacy of prim-O-glucosylcimifugin (POG) and investigate the molecular mechanisms of its therapeutic effects in atopic dermatitis (AD).
METHODS:
The effects of POG on human keratinocyte cell viability and its anti-inflammatory properties were evaluated using cell counting kit-8 assay and reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Subsequently, the impact of POG on the differentiation of cluster of differentiation (CD) 4+ T cell subsets, including T-helper type (Th) 1, Th2, Th17, and regulatory T (Treg), was examined through in vitro experiments. Network pharmacology analysis was used to elucidate POG's therapeutic mechanisms. Furthermore, the therapeutic potential of topically applied POG was further evaluated in a calcipotriol-induced mouse model of AD. The protein and transcript levels of inflammatory markers, including cytokines, lymphocyte-specific protein tyrosine kinase (Lck) mRNA, and LCK phosphorylation (p-LCK), were quantified using immunohistochemistry, RT-qPCR, and Western blot analysis.
RESULTS:
POG was able to suppress cell proliferation and downregulate the transcription of interleukin 4 (Il4) and Il13 mRNA. In vitro experiments indicated that POG significantly inhibited the differentiation of Th2 cells, whereas it exerted negligible influence on the differentiation of Th1, Th17 and Treg cells. Network pharmacology identified LCK as a key therapeutic target of POG. Moreover, the topical application of POG effectively alleviated skin lesions in the calcipotriol-induced AD mouse models without causing pathological changes in the liver, kidney or spleen tissues. POG significantly reduced the levels of Il4, Il5, Il13, and thymic stromal lymphopoietin (Tslp) mRNA in the AD mice. Concurrently, POG enhanced the expression of p-LCK protein and Lck mRNA.
CONCLUSION
Our research revealed that POG inhibits Th2 cell differentiation by promoting p-LCK protein expression and hence effectively alleviates AD-related skin inflammation.

In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma, this article systematically analyzes the historical evolution of the name, origin, harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica, prescription books, medical books and modern literature. The research results showed that Baiji(白及) was the main name, some scholars took Baiji(白芨) as its main name, and there were many other names such as Baiji(白给), Baigen(白根), Baiji(白苙). The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata, and drying, large, white, solid, root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials, there were certain differences between their traits, and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed, with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn, and harvested in autumn was better. The processing and processing technology is relatively simple, and it was used fresh or powdered in past dynasties, while it is mainly sliced for raw use in modern times. Based on the results, it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas, and it should be uniformly written as Baiji(白及). And if the original formula indicates the requirement of processing, it should be operated according to the requirement, if the requirement of processing is not indicated, it can be used in raw form as medicine.

OBJECTIVE To investigate the improvement effects of glycyrrhizin (GL) on Helicobacter pylori (HP)-associated gastritis in rats and its mechanism. METHODS HP-associated gastritis rat model was induced by inoculating with 1×109 cfu/mL HP. The model rats were randomly divided into model group, positive control group (HP standard quadruple group), GL low-dose, medium-dose and high-dose groups (5, 20, 50 mg/kg), with 12 rats in each group. Another 12 healthy rats were selected as normal control group. Except the normal control group and model group were given constant volume of normal saline intragastrically, the other groups were given corresponding drugs intragastrically, once a day, for 30 consecutive days. After administration, rats received 13C urea breath test, and delta-over-baseline (DOB) was recorded; the pathological and cellular morphological changes of gastric mucosa in rats were observed, and pathological scoring was performed; the levels of interleukin-8 (IL-8), IL-1β, tumor necrosis factor-α (TNF-α), reactive oxygen species (ROS) and malondialdehyde (MDA) were detected in gastric mucosa of rats; mRNA expressions of high mobility group box-1 protein (HMGB1) and nuclear factor-κ-B (NF-κB), relative expressions of nitric oxide synthases (iNOS) and HMGB1, the phosphorylation level of NF- κBp65 were also detected in rats. RESULTS Compared with normal control group, the DOB value, histopathological score of gastric mucosa, the levels of IL-8, IL-1β, TNF-α, ROS and MDA, relative expressions of HMGB1 and NF- κB mRNA, relative expressions of iNOS and HMGB1 protein and the phosphorylation level of NF-κB p65 were all increased significantly in model group (P<0.05); the epithelial cells of gastric mucosa in rats were incomplete in structure and decreased in the number, with an increase in cell fragments and vacuoles, and significant cell pyknosis. Compared with model group, the changes of the above indexes in GL groups and positive control group were significantly reversed (P<0.05); the changes in the above indicators in the GL high-dose group were more significant than GL low-dose and medium-dose groups (P<0.05); the pathological changes of gastric mucosal cells in rats had all improved. CONCLUSIONS GL may inhibit inflammation and oxidative stress by inhibiting the activation of HMGB1/NF-κB pathway, thus relieving HP-induced gastric mucosal injury.
