BackgroundClinical supervision is a critical component in the training and professional development of psychological counselors. Scientifically evaluating the effectiveness of clinical supervision is essential， yet reliable and effective tools for such assessments are lacing in China. ObjectiveTo translate Supervision Evaluation and Supervision Competence （SE-SC） Scale into Chinese version and evaluate its reliability and validity in clinical supervision in China， so as to provide a tool for the evaluation of supervisory effectiveness. MethodsThe SE-SC scale was translated， back-translated and culturally adapted， followed by a pilot survey to develop the Chinese version of SE-SC scale. A total of 42 counselors engaged in clinical counseling and receiving supervision at a counseling center in Shanghai from July 2021 to February 2022 were selected as the study participants. Item analysis was conducted to assess item discrimination， with critical ratio method applied to determine which items retention. Hierarchical cluster analysis was performed to compare the structure of Chinese version with the original scale. Criterion-related validity and convergent validity were used to evaluate the validity of the scale， while Cronbach's α coefficient was used to assess its reliability. ResultsChinese version of SE-SC scale consisted of a total of 28 item， including six clusters. Registered supervisors scored significantly higher than internship supervisors on the total score and on clusters three， four， five and six （t=2.536， 2.747， 5.881， 3.718， 6.090， P<0.05）. The total and cluster scores of the Chinese version of the SE-SC scale were positively correlated with self-rated supervision helpfulness and overall satisfaction （r=0.492~0.758， 0.412~0.815， P<0.01）. The Cronbach's α coefficient for the overall scale was 0.975，with values for the six clusters were 0.938， 0.821， 0.962， 0.871， 0.884 and 0.823， respectively. ConclusionChinese version of SE-SC scale demonstrates good reliability and validity， and it can be considered as a promising assessment tool for evaluating the effectiveness of clinical supervision.

OBJECTIVE: We aimed to investigate the patterns of fasting blood glucose (FBG) trajectories and analyze the relationship between various occupational hazard factors and FBG trajectories in male steelworkers. METHODS: The study cohort included 3,728 workers who met the selection criteria for the Tanggang Occupational Cohort (TGOC) between 2017 and 2022. A group-based trajectory model was used to identify the FBG trajectories. Environmental risk scores (ERS) were constructed using regression coefficients from the occupational hazard model as weights. Univariate and multivariate logistic regression analyses were performed to explore the effects of occupational hazard factors using the ERS on FBG trajectories. RESULTS: FBG trajectories were categorized into three groups. An association was observed between high temperature, noise exposure, and FBG trajectory ( P < 0.05). Using the first quartile group of ERS1 as a reference, the fourth quartile group of ERS1 had an increased risk of medium and high FBG by 1.90 and 2.21 times, respectively (odds ratio [ OR] = 1.90, 95% confidence interval [ CI]: 1.17-3.10; OR = 2.21, 95% CI: 1.09-4.45). CONCLUSION An association was observed between occupational hazards based on ERS and FBG trajectories. The risk of FBG trajectory levels increase with an increase in ERS.

The objective of this study was to analyze the effects on cell viability, apoptosis, and cell cycle of non-small cell lung cancer (NSCLC) A549 cells after intervention with Agrimonia pilosa (AP) and investigate Agrimonia pilosa anti-tumor activity in vitro. Meanwhile, liquid chromatography mass spectrometry (LC-MS) metabolomics technology was used to analyze the changes of cellular metabolites and metabolic pathways. The results of this study will provide a theoretical and experimental basis for investigating the mechanism of the effect of Agrimonia pilosa on non-small cell lung cancer A549 cells. The results showed that the cell nucleus of A549 cells crumpled and apoptosis occurred with the increase of drug concentration. The survival rate of the cells decreased, and the inhibition rate reached 21.5% and 91.74% under the low and high dose conditions, respectively. Lactate dehydrogenase (LDH) content increased (P < 0.05). Metabolomics results showed significant differences in metabolism between groups, thirty-three distinct metabolites including LysoPC(24:0/0:0), LysoPC(17:0/0:0) and PC(O-40:5) were deduced. The pathway enrichment showed that the Agrimonia pilosa plays an anti-tumor role mainly by regulating the metabolism of glycerophosphate and purine in A549 cells, in which the effect on glycerophosphate metabolism pathway was most significant. The results of combined pharmacodynamics suggested that Agrimonia pilosa might induce apoptosis and inhibit the growth of A549 cells by regulating LysoPC(24:0/0:0), LysoPC(17:0/0:0) and PC(O-40:5) metabolites in A549 cells.

NAD(P)H: quinone oxidoreductase 1 (NQO1) is a flavin protease highly expressed in various cancer cells. NQO1 catalyzes a futile redox cycle in substrates, leading to substantial reactive oxygen species (ROS) production. This ROS generation results in extensive DNA damage and elevated poly (ADP-ribose) polymerase 1 (PARP1)-mediated consumption of nicotinamide adenine dinucleotide (NAD⁺), ultimately causing cell death. Nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in the NAD⁺ salvage synthesis pathway, emerges as a critical target in cancer therapy. The concurrent inhibition of NQO1 and NAMPT triggers hyperactivation of PARP1 and intensive NAD⁺ depletion. In this study, we designed, synthesized, and assessed a novel series of proqodine A derivatives targeting both NQO1 and NAMPT. Among these, compound T8 demonstrated potent antitumor properties. Specifically, T8 selectively inhibited the proliferation of MCF-7 cells and induced apoptosis through mechanisms dependent on both NQO1 and NAMPT. This discovery offers a promising new molecular entity for advancing anticancer research.

Objective: To explore the current situation and related factors of AIDS discrimination among junior medical students in Jiangxi Province, so as to provide a reference for effective AIDS anti discrimination intervention measures in medical colleges. Methods: Using a convenience sampling approach, 2 484 medical students were selected from five universities in Jiangxi Province from July to August 2023. An anonymous survey was conducted using a general information questionnaire, a AIDS knowledge questionnaire, and the Chinese version of Zelaya s AIDS Stigma Scale. Independent sample t-tests and analysis of variance were carried out to analyze the level of AIDS discrimination among medical students with different characteristics. Multiple stepwise regression analysis was performed to identify the related factors of AIDS discrimination. Results: The total score of AIDS discrimination among medical students was (2.55±0.67). The dimension with the highest score was fear of contracting the disease (2.89±1.01). The results of the multiple stepwise regression analysis showed that the factors related to AIDS discrimination included gender ( β = -0.17 ), grade ( β =-0.08), being an only child or not ( β =-0.04), whether knowing about AIDS knowledge or not ( β =0.22), willingness to use condoms during sexual activity ( β =0.07), willingness to participate in school sexual health knowledge based activities ( β =0.05) and the perceived importance of selfhealth ( β =0.11) ( P <0.05). Conclusions AIDS discrimination is prevalent among junior medical students in Jiangxi Province. Efforts should be undertaken to enhance humanistic education and relevant knowledge dissemination among junior medical students to reduce the level of AIDS discrimination.

Objective:To compare the clinical outcomes between percutaneous Kirschner wire leverage plus plaster fixation and elastic intramedullary nailing in the treatment of radial neck fractures in children.Methods:A retrospective study was conducted to analyze the 60 children with radial neck fracture who had been treated by percutaneous Kirschner wire leverage plus plaster fixation at Department of Pediatric Orthopedics, Children's Hospital of Soochow University from January 2016 to July 2023 (set as an internal fixation-free group). They were 30 males and 30 females (34 left and 26 right sides) with an age of (7.7±3.0) years. At the same time, another cohort of 60 patients were chosen as an intramedullary nailing group who had been treated by percutaneous Kirschner wire leverage plus elastic intramedullary nailing and matched in age and gender with those in the internal fixation-free group. The preoperative fracture angulation, operative time, hospitalization time, fracture angulation on the first postoperative day, fracture angulation at 1 month postoperatively, rate of angulation loss after reduction, Mayo elbow performance score (MEPS) at the last follow-up and complications were compared between the 2 groups.Results:There was no significant difference between the 2 groups in their preoperative general data, showing comparability ( P<0.05). The 120 pediatric patients were followed up for (7.5±3.2) months. The operative time [(27.4±15.0) min] and hospitalization time [(3.4±1.9) d] in the internal fixation-free group were significantly shorter than those in the intramedullary nailing group [(45.4±13.5) min and (4.4±1.3) d] ( P<0.05). The preoperative fracture angulation (50.8°±1.9°), fracture angulation on the first postoperative day (11.3°±1.2°), fracture angulation at 1 month postoperatively (12.1°±1.3°), rate of angulation loss after reduction (2.9%±0.5%), and MEPS at the last follow-up [(90.4±2.0) points] in the internal fixation-free group showed no significant differences from those in the intramedullary nailing group [49.5°±1.7°, 11.1°±1.2°, 13.3°±1.5°, 3.9%±1.4%, and (90.2±2.3) points] ( P>0.05). None of the patients in the internal fixation-free group developed pin-tail irritation sign or premature epiphyseal closure after surgery, whereas 3 patients in the intramedullary nailing group developed pin-tail irritation sign and 2 ones premature epiphyseal closure after surgery, showing a significant difference in the complication rate between the 2 groups [0 (0/60) versus 8.3% (5/60)] ( P<0.05). Conclusions:Percutaneous Kirschner wire leverage plus plaster fixation and close elastic intramedullary nailing can both achieve satisfactory outcomes in the treatment of radial neck fractures in children. However, percutaneous Kirschner wire leverage plus plaster fixation needs shorter operative time and hospitalization time, leads to fewer complications, and requires no reoperation to remove internal fixation.

It is believed that children bronchiolitis obliterans （BO） is located at the lung and closely related to the spleen and kidney. Phlegm， stasis， block and deficiency are the main pathogenesis. This article promotes staged differentiation and treatment of BO considering the clinical manifestations and pathogenesis characteristics. The attack stage is dominated by phlegm and stasis blocking the lung， for which the method of dissolving phlegm and dispelling stasis， relieving cough and calming panting should be used； Xiaoqinglong Decoction（小青龙汤） and Sanzi Yangqin Decoction （三子养亲汤） with modifications and selfmade Modified Wuhu Decoction （五虎汤加味） are recommended for cold-phlegm blocking the lung syndrome and phlegm heat blocking the lung syndrome， respectively. In sustained stage， the upper excess and lower deficiency together with phlegm-stasis blocking the lung are the pathogenesis， for which the method of dissolving phlegm and dispelling stasis， reopening the block and supplementing deficiency is suggested， and Xiaoqinglong Decotion （小青龙汤） and Duqi pills （都气丸） with modifications can be used. In convalescent stage， the pathogenesis is lung-spleen-kidney depletion with residual pathogen. It suggested to supplement the deficiency and consolidate the root， as well as clear the residual pathogen， for which Baogen NO.1 Decoction （宝根1号方） with modifications can be used.

Objective To investigate the protective effects and mechanisms of dexmedetomidine(Dex)on kidney donors after warm ischemia and cold ischemia in rats.Methods A total of twenty-one male SD rats were randomly allocated into the control group,the model group(0 μmol/L Dex group)and the Dex group(1 μmol/L Dex group),with 7 rats in each group.All the rats were killed by bloodletting,the kidneys were extracted after 30 minutes of warm ischemia,and the kidneys of the control group were directly fixed or preserved at-80 ℃.The kidney donors of the model group and the Dex group were respectively refrigerated in the university of Wisconsin organ preserva-tion solution containing 0 μmol/L Dex and 1 μmol/L Dex at 4 ℃ for 24 hours,to simulate the cold ischemia state of the kidney donors.HE staining was performed to observe the morphological changes and the tissue injury score was conducted.The activity of N-acetyl-β-D-glucosaminase(NAG)was determined by colorimetry,the apoptosis level was detected by TUNEL,the expression level of receptor-interacting protein kinase 3(RIPK3)was detected by Western blot,and the expression level of phosphorylation mixed lineage kinase domain like protein(pMLKL)was determined by immunofluorescence method.Results In the control group,there were no obvious abnormalities in glomerular or renal tubules.In the model group,some renal tubules were dilated and tubular epithelial cells were flattened.Compared with the model group,the damage of renal tubules in the Dex group was alleviated.Compared with the control group,kidney injury score,NAG activity,TUNEL positive cell number,pMLKL and RIPK3 expression levels were increased in the model group and the Dex group(P＜0.05).Compared with the model group,kidney injury score,NAG activity,TUNEL positive cell number,and pMLKL expression level were decreased in the Dex group(P＜0.05).Conclusion Dex has protective effects on kidney donors after warm ischemia and cold ischemia,and its mechanism is related to reducing apoptosis and inhibiting necroptosis.
