Objective:To explore the effects of Circ_0000291 on proliferation,apoptosis and immune escape profiling of he-patocellular carcinoma(HCC)cells as a molecular sponge to regulate miR-326 through targeting polypyrimidine tract-binding protein 1(PTBP1).Methods:The expressions of Circ_0000291,miR-326 and PTBP1 in tissue samples and cells were measured by qRT-PCR.Dual luciferase reporter assay was employed to confirm the targeting relationship between Circ_0000291 and miR-326 as well as miR-326 and PTBP1.CCK-8 assay,Transwell assay,flow cytometry assay and ELISA were respectively utilized to determine the prolifera-tion,invasion,apoptosis and the expressions of immune regulation related factors(TNF-α,IFN-γ).Results:Compared with normal tissue and hepatic cells,Circ_0000291 and PTBP1 expressions were overexpressed in HCC tissue and cells,but the expression of miR-326 was obviously down-regulated(all P<0.05).Moreover,functional assays indicated that downregulation of Circ_0000291 could inhibit the proliferation,invasion,and immune escape while induce apoptosis of HCC cells(all P<0.05),which was according-ly exhibited in miR-326 transfection group.Overexpression of Circ_0000291 partly attenuated the anti-tumor effects induced by miR-326(all P<0.05).In HCC,Circ_0000291 could promote the expression of PTBP1 as a molecular sponge to regulate miR-326.Conclu-sion:Circ_0000291 served as a molecular sponge of miR-326 to increase PTBP1 expression and promote the proliferation,invasion and immune escape but inhibit apoptosis of HCC.There upon then,it facilitates the progression of HCC.

Objective:To evaluate the centralized endoscopy management at the disinfection supply center based on an intelligent traceable information system.Methods:From January 2021 to June 2022, 252 colonoscopes were selected after routine colonoscopy at the endoscopy center, and 126 colonoscopes were assigned to the observation group and 126 to the control group. The intelligent traceable information system was used for information input and access in the process of disinfection, washing, recycling and access. The control group administered decentralized management from the endoscopy center, while the observation group administered centralized management from the disinfection supply center. Adenosine triphosphate (ATP) biofluorescence detection method was used to compare the relative light unit values of the surface, the valve and the cavity of endoscopes of the two groups. The positive rate of microbe culture on the surface, the cavity, the biopsy mouth, the air injection mouth and the suction mouth were compared between the two groups. The contents of aerosol particles in endoscope cleaning environment were compared between the two groups. Staff satisfaction with recycling and usage were compared. The labor cost, operating cost and endoscope maintenance rate of centralized management and decentralized management were compared.Results:The qualified rates of valve and cavity cleaning in the observation group [94.4% (119/126), 93.7% (118/126)] were higher than those in the control group [90.5% (114/126), 88.9% (112/126); χ2=5.686, χ2=8.841, P<0.05]. The positive rates of microbial colony growth in the endoscopic cavity, biopsy mouth, air injection mouth and negative pressure suction mouth in the observation group [19.0% (24/126), 17.5% (22/126), 1.6% (2/126), 12.7% (16/126)] were lower than those in the control group [30.2% (38/126), 24.6% (31/126), 4.8% (6/126), 19.8% (25/126); χ2=12.215, χ2=9.003, χ2=6.446, χ2=9.106, P<0.05]. The 0.5 μm and 2.5 μm aerosol particles produced by air in the observation group (40 706 874 ±12 563 749 /m 3, 226 530±87 632 /m 3) were lower than those in the control group (46 892 654±13 209 872 /m 3, 263 281±45 219 /m 3; t=8.223, t=4.265, P<0.05). The labor cost and the operating cost of the observation group were 63 128.45 yuan and 56 320.13 yuan respectively, which were lower than 208 258.25 yuan and 208 415.22 yuan in the control group. The satisfaction with recycling and usage in the observation group [96.1% (98/102), 97.1% (100/103)] was higher than that in the control group [78.4% (80/102), 82.5% (85/103); χ2=13.211, χ2=15.223, P<0.05]. There was no endoscopic maintenance in the observation group, and 2 cases of endoscopic maintenance in the control group.

Objective:To explore the effectiveness of streamlined modular teaching based on the organ system in standardized residency training in emergency medicine.Methods:We enrolled residents on standardized training in the Second Clinical College of Tongji Medical College of Huazhong University of Science and Technology from July 2020 to July 2021. They were randomly divided in a 1∶1 ratio into conventional group (25 trainees, adopting a traditional standardized teaching method) and modular group (25 trainees, adopting streamlined modular teaching based on the organ system in addition to the method of the conventional group). At the end of training, all the trainees were assessed for academic performance and teaching-related indicators through an exam and questionnaire survey, and the teachers were surveyed for the degree of satisfaction with the teaching method. Data were analyzed by the t-test and chi-squared test using SPSS 21.0 software. Results:The modular group had a significantly higher total final exam score than the conventional group [(93.52±0.49) vs. (84.44±0.57), t=12.02, P<0.001]. Specifically, the modular group had significantly higher scores than the conventional group in emergency medicine theory, medical history taking and writing, physical examination and procedures, interpretation of examination results, and treatment and management ( t=3.62, 4.29, 4.22, 10.09, 7.56, all P<0.001). The modular group was also superior to the conventional group in terms of teaching-related indicators (all P<0.05). All participating teachers were satisfied with the new teaching method. Conclusions:The streamlined modular teaching method based on the organ system is beneficial for the standardized training of residents in emergency medicine, which is worthy of promotion.

Objective This study aimed to estimate the therapeutic effects of preformed metal crown(PMC)and pre-fabricated zirconia crowns(ZC)on decayed primary morals in children,as well as to analyze the possible influencing fac-tors.Methods A retrospective cohort study was performed on the data of 192 patients(aged 3 to 8)in the Stomatologi-cal Department of Shenzhen Children's Hospital from October 2021 to December 2021.The decayed mandibular first molars were selected and restored by vital-pulp therapy followed by PMC and ZC,including 96 cases(96 caries)in the PMC group and 96 cases(96 caries)in the ZC group.Oral clinical examination was performed at 3 months,1 year,and 2 years after treatment,overwiewing the clinical therapeu-tic effects and periodontal status of PMC and ZC groups,as well as recording the crown integrity,gingival index(GI),probing bleeding index(BI),plaque index(PLI)and various prosthetic indices.Results No significance differences existed in the periodontal status of PMC and ZC groups at 3 months,1 year,and 2 years after treatment(P>0.05).However,the GI,BI,and PLI in the PMC group were higher than those in the ZC group at 3 months,1 year,and 2 years after treatment,and the difference was dramatically signifi-cant(P<0.05).No significances difference existed in various prosthetic indices(P>0.05),as well as in the GI,BI,and PLI,between the two groups(P>0.05).No significant differences existed in various prosthetic indices between genders after PMC restoration(P>0.05).The scores of girls in various prosthetic indices after ZC restoration were higher than those of boys(P<0.05).Pearson correlation analysis indicated an inverse correlation between age in the PMC group and the GI,BI,PLI,and FDI indices(P<0.01),rather than in the ZC group(P>0.05).Conclusion PMC and ZC can be ap-plied to restore deciduous molar caries.The periodontal status of deciduous teeth in ZC group was superior to that in the PMC group.The periodontal status of deciduous teeth in PMC group may be stable with increased age.

The mechanisms of the chronic pain and depression comorbidity have gained significant attention in recent years. The complement system, widely involved in central nervous system diseases and mediating non-specific immune mechanisms in the body, remains incompletely understood in its involvement in the comorbidity mechanisms of chronic pain and depression. This review aims to consolidate the findings from recent studies on the complement system in chronic pain and depression, proposing that it may serve as a promising shared therapeutic target for both conditions. Complement proteins C1q, C3, C5, as well as their cleavage products C3a and C5a, along with the associated receptors C3aR, CR3, and C5aR, are believed to have significant implications in the comorbid mechanism. The primary potential mechanisms encompass the involvement of the complement cascade C1q/C3-CR3 in the activation of microglia and synaptic pruning in the amygdala and hippocampus, the role of complement cascade C3/C3a-C3aR in the interaction between astrocytes and microglia, leading to synaptic pruning, and the C3a-C3aR axis and C5a-C5aR axis to trigger inflammation within the central nervous system. We focus on studies on the role of the complement system in the comorbid mechanisms of chronic pain and depression.

Objective:To investigate the status of disaster preparedness of pediatric nurses and its influencing factors, as well as the impact path of psychological capital and perceived organizational support on disaster preparedness.Methods:This was a cross-sectional study. A total of 361 pediatric nurses from Henan Provincial People ′s Hospital, the Third Affiliated Hospital of Zhengzhou University, Fuwai Central China Cardiovascular Hospital were sampled from August to October 2021. They were investigated by the general information questionnaire, psychological capital questionnaire, perceived organizational support questionnaire and disaster preparedness questionnaire. SPSS25.0 was used to analyze the questionnaire and scale data, and AMOS23.0 was used to construct a structural equation model about the disaster preparedness of pediatric nurses. Results:The scores of disaster preparedness from pediatric nurses was 4.65 ± 0.92. The level of disaster preparedness was significantly positively correlated with psychological capital and perceived organizational support ( r=0.690, 0.525, both P<0.05). Disaster training and emergency drill 2 dimensions of psychological capital questionnaire (hope, resilience), perceived organizational support were independent contributing factors ( P<0.05). Psychological capital had direct effect on disaster preparedness. And the direct effect was 0.77, the indirect effect was 0.11, the total effect was 0.88, and the direct effect of perceived organizational support on disaster preparedness was 0.21. Conclusions:The score of disaster preparedness of pediatric nurses was in the middle level. Hospital managers should strengthen the training of pediatric nurses in disaster knowledge, operational and simulation exercise, pay attention to the level of nurses' psychological capital and perceived organizational support, so as to provide reference for the follow-up clinical pediatric disaster nursing education and management.

Objective To investigate the mechanism of action of Huzhang Qingmai decoction (HZQMY) on the improvement of cognitive function in mice with chronic cerebral ischemia from the perspective of intestinal flora. Methods A mouse model of chronic cerebral ischemia was established by placing microcoils around the bilateral common carotid arteries to induce bilateral carotid artery stenosis (BCAS). After 12 weeks of intragastric administration, the cognitive function of the mice was measured by the Morris water maze; the myelin damage was analyzed by LFB staining; The contents of the cecum of the mice in each group were extracted and analyzed by 16S rRNA sequencing. Results The results of the water maze experiment showed that the mice in the HZQMY group had a significantly shorter escape latency, increased the number of crossings platform and the percentage of target quadrants. LFB staining showed that the white matter damage in the model group was severe; the white matter damage in the HZQMY group was milder. The results of 16S rRNA sequencing showed that compared with the model group, the abundance of Verrucomicrobiota, Akkermansia, and ErysiPelatoclostridium capsulatum in the intestinal flora in HZQMY group was significantly reduced (P<0.05), while the abundances of Eubacterium_xylanoPhilum and Allobaculum were significantly increased (P<0.05). Conclusion The protective effect of HZQMY, which has the effect of improving cognitive function in mice with chronic cerebral ischemia, may be related to the regulation of intestinal flora in mice with chronic cerebral ischemia.

Objective To explore the mechanism of motherwort in the treatment of nerve injury. Methods The active components of motherwort were obtained by searching TCMSP and BATMAN-TCM databases. The action targets of candidate compounds were collected and predicted from TCMSP and SwissTargetPrediction (STP) databases. The target genes corresponding to the active components of motherwort were obtained by using the standardized database of disease targets (Uniprot). The potential targets of motherwort in the treatment of nerve injury were obtained by mapping the disease genes of nerve injury with the three databases of Genecards, DisGenet and OMIM. The network topology analysis software Cytoscape 3.6.0 was used to construct the action target network of motherwort active components. The protein interaction platform database (STRING) was used to construct the interaction relationship between action targets. The target protein interaction (PPI) network was constructed by introducing Cytoscape 3.6.0 software. Through STRING database, GO enrichment analysis and KEGG pathway enrichment analysis were carried out to analyze the target points of motherwort in the treatment of nerve injury. Results 19 active components were screened from motherwort, involving 654 action targets, including 426 action targets related to nerve injury and 6 key targets. These target genes were mainly involved in biological regulation, oxidative stress response and cell communication and other biological processes. Molecular functions were mainly related to protein binding, ion binding and catalytic reduction. They were enriched outside the cell membrane. Its mechanism was related to signal pathways such as MAPK, Toll-like receptor, PI3K-Akt, TNF, IL-17, and apoptosis. Conclusion The active components of motherwort may play a protective role on nerve injury through anti-inflammation, anti-apoptosis and promoting cell growth.

Vanin-1 is an amidohydrolase that catalyses the conversion of pantetheine into the amino-thiol cysteamine and pantothenic acid (coenzyme A precursor), which plays a vital role in multiple physiological and pathological processes. In this study, an enzyme-activated near-infrared (NIR) fluorescent probe (DDAV) has been constructed for sensitively detecting Vanin-1 activity in complicated biosamples on the basis of its catalytic characteristics. DDAV exhibited a high selectivity and sensitivity toward Vanin-1 and was successfully applied to the early diagnosis of kidney injury in cisplatin-induced kidney injury model. In addition, DDAV could serve as a visual tool for in situ imaging endogenous Vanin-1 in vivo. More importantly, Enterococcus faecalis 20247 which possessed high expression of Vanin-1 was screened out from intestinal bacteria using DDAV, provided useful guidance for the rational use of NSAIDs in clinic. Finally, oleuropein as a potent natural inhibitor for Vanin-1 was discovered from herbal medicines library using a high-throughput screening method using DDAV, which held great promise for clinical therapy of inflammatory bowel disease.
