OBJECTIVE To investigate the effects of multiple doses of Shugan jieyu capsules on the pharmacokinetics of voriconazole, rivaroxaban and apixaban in rats. METHODS Male SD rats were randomly divided into voriconazole group (30 mg/kg), rivaroxaban group (2 mg/kg), apixaban group (0.5 mg/kg), Shugan jieyu capsules+voriconazole group (145 mg/kg+30 mg/kg), Shugan jieyu capsules+rivaroxaban group (145 mg/kg+2 mg/kg), Shugan jieyu capsules+apixaban group (145 mg/kg+0.5 mg/kg), with 6 rats in each group. After the rats in each group were consecutively administered solvent (0.5% sodium carboxymethyl cellulose solution) or Shugan jieyu capsules by intragastric gavage for 8 days, they were respectively given voriconazole, rivaroxaban and apixaban solution by intragastric gavage on the 8th day. Blood samples were then collected at different time points (in voriconazole group, rivaroxaban group and corresponding drug combination groups, blood was collected before administration and at 0.17, 0.34, 0.5, 0.75, 1, 1.5, 2, 3, 4, 5, 6, 8, 10 and 12 hours post-administration; in apixaban group and corresponding drug combination group, blood was collected before administration and at 0.08, 0.17, 0.25, 0.34, 0.5, 0.75, 1, 3, 5, 7, 10 and 12 hours post-administration). Ultra-high performance liquid chromatography-tandem mass spectrometry method was employed to determine the mass concentrations of voriconazole, rivaroxaban and apixaban in rat plasma. The main pharmacokinetic parameters of these drugs were calculated using a non-compartmental model, and the comparisons were made between groups. RESULTS Compared with single drug group, after multiple administrations of Shugan jieyu capsules, AUC0-t, AUC0-∞ and cmax of voriconazole were significantly decreased, while CLz/F was significantly increased, and tmax was also significantly prolonged (P<0.05). For rivaroxaban and apixaban, their tmax values were both significantly prolonged (P<0.05). However, there were no statistically significant differences in the other pharmacokinetic parameters between the two groups (P>0.05). CONCLUSIONS The combination of Shugan jieyu capsules can decrease the exposure, increase the clearance, and delay the peak concentration of oral voriconazole. However, it does not affect the exposure levels of rivaroxaban and apixaban, but it does delay the time to reach peak concentration for both drugs.

Background:
The Korean Occupational Stress Scale (KOSS) was developed in 2004. During this time, industrial structures have evolved, and societal awareness of occupational stress has changed. This study aims to develop and validate a revised version of the Korean Occupational Stress Scale (KOSS®19), tailored for workers, reflecting these changes.
Methods:
The KOSS®19 was developed based on the 26-item KOSS–short form (SF) through a review by eight experts. A survey was conducted including 359 service industry workers, comprising the KOSS®19, Burnout, and Depression scales. The KOSS®19 subscales were restructured, and their reliability and validity were evaluated.
Results:
The KOSS®19 composed of eight subscales: hazardous physical environment (2 items), high job demand (3 items), insufficient job control (2 items), low social support (2 items), job insecurity (2 items), organizational injustice (4 items), lack of reward (2 items), and work-life imbalance (2 items). The reliability and validity of the KOSS®19 were found to be satisfactory.
Conclusions
The KOSS®19 is a suitable tool for assessing occupational stress, effectively replacing the original KOSS and KOSS-SF.

Background:
Emotional labor refers to the management of emotions and expressions to meet the emotional requirements of a job role. This study aimed to develop a revised version of the Korean Emotional Labor Scale (KELS®11), based on the first edition (KELS-24) introduced in 2014, and to provide practical applications and guidelines for its use in the Korean workplace through a validation process.
Methods:
The revised version of KELS®11 was derived from the 24-item KELS, following a review process involving eight experts. To validate the scale’s reliability and validity, a self-administered survey was conducted among 359 service industry workers using KELS®11, burnout, and depression scales. KELS®11 was reclassified, and its reliability and validity were evaluated. Receiver operating characteristic curve analysis was conducted to establish sex-specific cutoff values (normal vs. high-risk groups).
Results:
KELS®11 was designed to account for individual, organizational, and cultural contexts. It consists of four subscales and 11 items: “emotional regulation” (2 items), “emotional dissonance” (3 items), “organizational monitoring” (2 items), and “organizational protective system for emotional labor” (4 items). KELS®11 demonstrated good validity (content validity ratio: 0.84; item convergence/discriminant validity success rates: 100%; correlation with burnout: r = 0.185–0.436, p < 0.01; correlation with depression: r = 0.128–0.339, p < 0.05) and reliability (Cronbach’s alpha: 0.597–0.795). Additionally, sex-specific reference values were established to determine risk groups based on the intensity of emotional labor exposure.
Conclusions
KELS®11 is a validated and reliable measurement tool designed to assess the intensity and magnitude of emotional labor in the workplace. The revised tool reflects critical considerations in the development of emotional labor measurement scales.

Background:
Workplace violence refers to any act or threat of physical violence, verbal abuse, harassment, intimidation, bullying, mobbing, or other aggressive and disruptive behaviors that occur at work. This study aims to develop and validate a revision of the Korean Workplace Violence Scale (KWVS®13), based on the first edition of the Korean Workplace Violence Scale (KWVS-24), and to provide practical applications and guidelines for the Korean workplace environment.
Methods:
The revised KWVS®13 was developed by restructuring the 24-item KWVS through a review process involving eight experts. To validate the reliability and validity of KWVS®13, a self-administered survey comprising KWVS®13, burnout, and depression scales was conducted among 359 service industry workers. KWVS®13 was reclassified, and its reliability and validity were assessed. Receiver operating characteristic curve analysis was performed to establish sex-specific cutoff values (normal vs. risk) of the scale.
Results:
KWVS®13 consists of 13 items across four subscales: “psychological and sexual violence from customers” (4 items), “psychological and sexual violence from supervisors or coworkers” (4 items), “physical assault from customers, supervisors, or coworkers” (2 items), and “organizational protective system for workplace violence” (3 items). We found that KWVS®13 shows relatively good validity (content validity ratio for content validity: 0.888; success rate of item convergent and discriminant validity: 100%, and significant correlation coefficient with burnout (r = 0.115–0.83, p < 0.05) and depression (r = 0.098–0.348, p < 0.05) with the exception of Organizational Violence Protection System for Workplace Violence) and reliability (Cronbach’s alpha: 0.827–0.860). The reference values for determining risk groups according to the intensity of exposure to workplace violence are presented separately by sex.
Conclusions
KWVS®13 is a robust and useful measurement tool to objectively and quantitatively assess the intensity and magnitude of workplace violence. It incorporates important considerations for workplace violence assessment and provides a reliable framework for evaluating workplace violence in various professional settings.

Background::Differentiated thyroid cancer (DTC) is commonly diagnosed in women of child-bearing age, but whether pregnancy influences the prognosis of DTC remains controversial. This study aimed to summarize existing evidence regarding the association of pregnancy with recurrence risk in patients previously treated for DTC.Methods::We searched PubMed, Embase, Web of Science, Cochrane, and Scopus based on the prespecified protocol registered at PROSPERO (CRD42022367896). After study selection, two researchers independently extracted data from the included studies. For quantitative data synthesis, we used random-effects meta-analysis models to pool the proportion of recurrence (for pregnant women only) and odds ratio (OR; comparing the risk of recurrence between the pregnancy group and the nonpregnancy group), respectively. Then we conducted subgroup analyses to explore whether risk of recurrence differed by response to therapy status or duration of follow-up time. We also assessed quality of the included studies.Results::A total of ten studies were included. The sample size ranged from 8 to 235, with participants’ age at pregnancy or delivery ranging from 28 to 35 years. The follow-up time varied from 0.1 to 36.0 years. The pooled proportion of recurrence in all pregnant patients was 0.13 (95% confidence intervals [CI]: 0.06-0.25; I2: 0.58). Among six included studies reporting response to therapy status before pregnancy, we observed a trend for increasingly higher risk of recurrence from excellent, indeterminate, and biochemically incomplete to structurally incomplete response to therapy ( Ptrend <0.05). The pooled risk of recurrence in the pregnancy group showed no evidence of a significant difference from that in the nonpregnancy group (OR: 0.75; 95% CI: 0.45-1.23; I2: 0). The difference in follow-up time (below/above five years) was not associated with either the proportion of recurrence in all pregnant patients ( P >0.05) or the OR of recurrence in studies with a comparison group ( P >0.05). Two included studies that focused on patients with distant metastasis also did not show a significant difference in disease recurrence between pregnancy and nonpregnancy groups (OR: 0.51 [95% CI: 0.14-1.87; I2: 59%]). Conclusion::In general, pregnancy appears to have a minimal association with the disease recurrence of DTC with initial treatment. Clinicians should pay more attention to progression of DTC among pregnant women with biochemical and/or structural persistence.Registration::PROSPERO, https://www.crd.york.ac.uk/PROSPERO/; No. CRD42022367896.

Objective:To investigate the effects of modified endoscopic retrograde appendicitis therapy (mERAT) on the treatment of children with different severities of acute appendicitis.Methods:This study was a case-control study. A total of 586 children with acute appendicitis, who were admitted to the Pediatric Department of Second Affiliated Hospital of Air Force Medical University between January 2019 and November 2023, were selected as the research subjects. According to the severity of the disease, the patients were divided into simple appendicitis group, suppurative appendicitis group and perforated appendicitis group. The baseline data, hospitalization treatment and costs, outcomes, and recurrence in each group were analyzed, and the difference in the effectiveness of mERAT between the groups were compared by Kruskal-Wallis H test and χ2 test. Results:Among 586 children, there were 338 males and 248 females. The age at onset was 7.0 (4.6, 9.4) years. There were 475 cases of simple appendicitis, 78 cases of suppurative appendicitis, and 33 cases of perforated appendicitis. There were no significant differences in age and gender among the three groups ( F=0.59, χ2=3.31, both P>0.05). However, there were statistically significant differences in body temperature, white blood cell counts, neutrophil percentage, lymphocyte percentage, nausea or vomiting, right lower abdominal pain, umbilical pain, right lower abdominal tenderness, and right lower abdominal rebound pain ( H=7.56, 161.52, 169.11, and 169.61, χ2=12.05, 13.82, 12.05, 7.74, 20.35, and 94.61, all P<0.05). Also, the treatment time, postoperative hospital stay, total hospital stay, and cost showed statistically significant differences ( H=4.70, 33.66, 34.99, 30.37, all P<0.05). There was no significant difference in the initial treatment success rate (98.1% (466/475) vs. 98.7% (77/78) vs. 90.9% (30/33), P=0.057). During the 30 (23, 36) months of follow-up, the recurrence rate was 7.9% (35/433) in the simple appendicitis group, 20.8% (15/72) in the suppurative appendicitis group, and 30.0% (9/30) in the perforated appendicitis group, with a statistically significant difference ( χ2=23.56, P<0.001). Among the children with recurrent appendicitis, 15 cases still chose mERAT, of them 11 cases (31.2%) had simple appendicitis, 2 cases (2/15) had suppurative appendicitis, and 2 cases (2/9) had perforated appendicitis.The latest time to recurrence in the 3 groups was 32, 35 and 10 months, respectively. Conclusion:Treatment with mERAT has a good effect in pediatric simple appendicitis, but has a higher recurrence rate despite a better initial treatment success rate in suppurative appendicitis and perforated appendicitis.

In order to investigate the molecular mechanism of silk/threonine protein kinase (STK)-mediated blue light response in the algal Chlamydomonas reinhardtii, phenotype identification and transcriptome analysis were conducted for C. reinhardtii STK mutant strain crstk11 (with an AphvIII box reverse insertion in stk11 gene coding region) under blue light stress. Phenotypic examination showed that under normal light (white light), there was a slight difference in growth and pigment contents between the wild-type strain CC5325 and the mutant strain crstk11. Blue light inhibited the growth and chlorophyll synthesis in crstk11 cells, but significantly promoted the accumulation of carotenoids in crstk11. Transcriptome analysis showed that 860 differential expression genes (DEG) (559 up-regulated and 301 down-regulated) were detected in mutant (STK4) vs. wild type (WT4) upon treatment under high intensity blue light for 4 days. After being treated under high intensity blue light for 8 days, a total of 1 088 DEGs (468 upregulated and 620 downregulated) were obtained in STK8 vs. WT8. KEGG enrichment analysis revealed that compared to CC5325, the crstk11 blue light responsive genes were mainly involved in catalytic activity of intracellular photosynthesis, carbon metabolism, and pigment synthesis. Among them, upregulated genes included psaA, psaB, and psaC, psbA, psbB, psbC, psbD, psbH, and L, petA, petB, and petD, as well as genes encoding ATP synthase α, β and c subunits. Downregulated genes included petF and petJ. The present study uncovered that the protein kinase CrSTK11 of C. reinhardtii may participate in the blue light response of algal cells by mediating photosynthesis as well as pigment and carbon metabolism, providing new knowledge for in-depth analysis of the mechanism of light stress resistance in the algae.

WRKY is a superfamily of plant-specific transcription factors, playing a critical regulatory role in multiple biological processes such as plant growth and development, metabolism, and responses to biotic and abiotic stresses. Although WRKY genes have been characterized in a variety of higher plants, little is known about them in eukaryotic algae, which are close to higher plants in evolution. To fully characterize algal WRKY family members, we carried out multiple sequence alignment, phylogenetic analysis, and conserved domain prediction to identify the WRKY genes in the genomes of 30 algal species. A total of 24 WRKY members were identified in Chlorophyta, whereas no WRKY member was detected in Rhodophyta, Glaucophyta, or Bacillariophyta. The 24 WRKY members were classified into Ⅰ, Ⅱa, Ⅱb and R groups, with a conserved heptapeptide domain WRKYGQ(E/A/H/N)K and a zinc finger motif C-X4-5-C-X22-23-H-X-H. Haematococcus pluvialis, a high producer of natural astaxanthin, contained two WRKY members (HaeWRKY-1 and HaeWRKY-2). Furthermore, the coding sequences of HaeWRKY-1 and HaeWRKY-2 genes were cloned and then inserted into prokaryotic expression vector. The recombinant vectors were induced to express in Escherichia coli BL21(DE3) cells and the fusion proteins were purified by Ni-NTA affinity chromatography. HaeWRKY-1 had significantly higher expression level than HaeWRKY-2 in H. pluvialis cultured under normal conditions. High light stress significantly up-regulated the expression of HaeWRKY-1 while down-regulated that of HaeWRKY-2. The promoters of HaeWRKY genes contained multiple cis-elements responsive to light, ethylene, ABA, and stresses. Particularly, the promoter of HaeWRKY-2 contained no W-box specific for WRKY binding. However, the W-box was detected in the promoters of HaeWRKY-1 and the key enzyme genes HaeBKT (β-carotene ketolase) and HaePSY (phytoene synthase) responsible for astaxanthin biosynthesis. Considering these findings and the research progress in the related fields, we hypothesized that the low expression of HaeWRKY-2 under high light stress may lead to the up-regulation of HaeWRKY-1 expression. HaeWRKY-1 may then up-regulate the expression of the key genes (HaeBKT, HaePSY, etc.) for astaxanthin biosynthesis, consequently promoting astaxanthin enrichment in algal cells. The findings provide new insights into further analysis of the regulatory mechanism of astaxanthin biosynthesis and high light stress response of H. pluvialis.

ObjectiveTo explore the intervention effect and mechanism of Buzhong Yiqiwan (BZYQ) on colitis mice. MethodSixty-four C57BL/6 mice were randomly divided into 2 weeks blank group, 2 weeks model group, 2 weeks high-dose BZYQ (12 g·kg-1) group, 2 weeks low-dose BZYQ (6 g·kg-1) group, 4 weeks blank group, 4 weeks model group, 4 weeks high-dose BZYQ (12 g·kg-1) group, and 4 weeks low-dose BZYQ (6 g·kg-1) group. The colitis model was induced in mice by feeding 3% dextran sodium sulfate (DSS) for 7 days. The mice received BZYQ (12 and 6 g·kg-1) by gavage on the 8th day after modeling, once per day, and sacrificed on the 2nd and 4th weeks, correspondingly. The colon length and weight of mice in each group were measured. Hematoxylin-eosin (HE) staining was used for pathological observation and colonic mucosal inflammation was scored. The mRNA and protein expression of NOD-like receptor thermoprotein domain 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), and cysteinyl aspartate-specific protease-1 (Caspase-1) was detected by real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to detect the content of inflammatory cytokines, such as interleukin (IL)-1β, IL-18, and IL-33 in colonic tissues. ResultCompared with the 2 weeks blank group, the 2 weeks model group showed shortened colon length, increased colon weight (P<0.05), loss of epithelial cells, destruction of gland structure, infiltration of a large number of inflammatory cells in mucosa and submucosa, local crypt abscess, and increase in mucosal inflammation score (P<0.01) as revealed by light microscopy, elevated levels of IL-1β, IL-18, and IL-33 in colonic tissues (P<0.05), and increased mRNA and protein expression of NLRP3, ASC, and Caspase-1 (P<0.05). The intervention of BZYQ (12 g·kg-1) restored colon length, alleviated mucosal injury (P<0.05), down-regulated the content of IL-18 (P<0.05), reduced the mRNA expression of NLRP3 and ASC as well as the protein expression of ASC and Caspase-1 compared with the conditions in the 2 weeks model group. Compared with the 4 weeks blank group, the 4 weeks model group showed decreased colon length, increased colon weight (P<0.05), decreased glands in the mucosal layer, expansion of glandular cavity, atrophy of crypt, local connective tissue hyperplasia and lymphocyte infiltration, increased inflammation score (P<0.01) as revealed by the light microscopy, increased expression of IL-1β, IL-18, and IL-33 (P<0.05), and elevated mRNA and expression of NLRP3 inflammasome complex (P<0.05). Compared with the conditions in the 4 weeks model group, the intervention of BZYQ (12 and 6 g·kg-1) could improve colon length and weight (P<0.05), and the intervention of BZYQ (12 g·kg-1) could also improve the inflammation score of the colon (P<0.05). Different from the acute stage, the intervention of BZYQ (12 and 6 g·kg-1) increased the content of IL-33 in the intestinal mucosa and up-regulated the mRNA and protein expression of NLRP3 inflammasome complexes ASC and Caspase-1 (P<0.05). ConclusionBZYQ can relieve the injury of colitis induced by DSS in mice. The mechanism is related to the regulation of intestinal immune response mediated by NLRP3 inflammasome, and it has different regulatory effects in acute and chronic inflammation stages.
