    Objective To investigate the role of piRNA-020829(piR-020829)in regulating malignant proliferation of hepatocellular carcinoma(HCC)and its underlying molecular mechanism. Methods Quantitative real-time PCR was used to detect the expression levels of piR-020829 in HCC tissues and adjacent non-tumor liver tissues. Kaplan-Meier survival analysis was performed to evaluate the correlation between piR-020829 expression and overall survival(OS)and progression-free survival(PFS)in HCC patients. Short hairpin RNA interference technology was employed to knock down piR-020829 expression in SNU387 cells(knockdown group), with SNU387 cells transfected with negative control vector serving as negative control group. piR-020829 mimic was used to overexpress piR-020829 in Hep3B cells(overexpression group), with Hep3B cells transfected with mimic negative control serving as overexpression negative control group. CCK-8 assay was used to detect cell proliferation viability in SNU387/Hep3B cells after piR-020829 knockdown or overexpression. For in vivo experiments, 32 nude mice were randomly divided into 4 groups: antagomir group(tail vein injection of piR-020829 Antagomir), antagomir control group(injection of Antagomir NC), mimic group(injection of piR-020829 mimic), and mimic control group(injection of mimic NC); tumor weight was observed in each group at the end of the experiment. Colony formation assay was used to detect the in vitro proliferative capacity of SNU387/Hep3B cells after piR-020829 knockdown or overexpression. Results Compared with adjacent normal tissues, the expression level of piR-020829 was significantly elevated in hepatocellular carcinoma(HCC)tissues. Survival analysis showed that HCC patients with relatively high expression of piR-020829 had significantly shorter overall survival and progression free survival than those with low expression, indicating that high piR-020829 expression predicts a poor prognosis in HCC patients. In vitro experiments confirmed that knockdown of piR-020829 led to a significant decrease in the proliferation viability and colony formation ability of HCC cells(P<0.05), while treatment with piR-020829 mimic increased HCC cell proliferation activity and colony formation. Nude mouse subcutaneous xenograft experiments demonstrated that treatment with piR-020829 Antagomir resulted in a significantly lower tumor weight compared with the antagomir control group, whereas treatment with piR-020829 mimic led to a significantly higher tumor weight compared with the mimic control group. Immunohistochemical staining of xenograft tumors from the antagomir group showed a significantly lower Ki-67 positive rate than that in the antagomir control group(P<0.05). Knockdown of piR-020829 downregulated the expression of the apoptosis-related proteins B-cell lymphoma-2(Bcl-2)and B-cell lymphoma-xl(Bcl-xl), and upregulated the expression of cysteine-aspartic protease 3(Caspase-3)(P<0.05). Knockdown of piR-020829 also downregulated the expression of the cell cycle-related proteins CDK4 and Cyclin D1(P<0.05). Furthermore, mechanistic investigation revealed that knockdown of piR-020829 significantly upregulated the expression of its target molecule insulin-like growth factor-binding protein 3(IGFBP3)(P<0.05). Conclusion piR-020829 promotes malignant proliferation of HCC cells by targeting and inhibiting IGFBP3 expression, and this molecule may serve as a novel molecular target for anti-HCC targeted therapy.

    Objective To investigate the key downstream genes and molecular mechanisms through which C16∶0 ceramide activates formyl peptide receptor 2(FPR2)to regulate thermogenesis in brown adipose tissue(BAT). Methods Using mouse BAT as the research model, mice were intraperitoneally injected with C16∶0 ceramide [10 mg/(kg·d)] or vehicle for three consecutive days, followed by exposure to 4 ℃ for 24 h. The expression level of uncoupling protein 1(UCP1)in BAT was detected by Western blotting and qPCR. Transcriptome sequencing was further employed to identify genes involved in C16∶0 ceramide-mediated regulation of BAT thermogenesis, and the screened genes were validated by qPCR. Results C16∶0 ceramide significantly reduced both the mRNA expression level of UCP1 in BAT [(0.608±0.066)vs.(1.001±0.033), F=3.879, P=0.017 [and its protein level [(0.725±0.036)vs.(1.000±0.043), F=1.365, P=0.008]. Transcriptome sequencing identified 909 differentially expressed genes(620 up-regulated and 289 down-regulated). GO and KEGG enrichment analyses showed that C16∶0 ceramide significantly down-regulated the peroxisome proliferators-activated receptor(PPAR)and forkhead box O(FOXO)signaling pathways, from which seven genes(SLC27A2、HMGCS2、EHHADH、PCK1、IRS2、SGK2, and PLK3)were selected. Validation in Sox2-CreER+/-Fpr2fl/fl mice revealed that their expression was specifically regulated by the C16∶0 ceramide-FPR2 axis. Conclusion C16∶0 ceramide down-regulates UCP1 expression in mouse BAT via FPR2. This mechanism is closely associated with the PAR and FoxO signaling pathways, and inhibits BAT thermogenesis by regulating the expression of SLC27A2,HMGCS2,EHHADH,PCK1,IRS2,SGK2 and PLK3.

    Objective To investigate the impact of surgical learning curves on complications and intraoperative key indicators after laparoscopic radical hysterectomy for women with cervical cancer. and to analyze, the association between the surgical learningcurve and postoperative complications, so as to provid a theoretical reference for quality controland surgeon training. Methods A total of 102 patients who were diagnosed with early-stage cervical cancer and underwent laparoscopicradical hysterectomy were enrolled in the study. All patients were operated on by the same senior surgeon(chief physician)at the Second Qilu Hospital of Shandong University.Cumulative sum(CUSUM)analysis based on operative time was applied to model the learning curve, dividing the cases into two phases: the learning phase(the first 29 cases)and the mastery phase(the subsequent 73 cases). Intraoperative parameters and postoperative complication rates were then compared between these two phases. Results The optimal CUSUM fitting equation was CUSUMn=-117.850+89.4n-1.759n2+0.009n3(R2=0.956, P<0.05), indicating a strong model fit. Based on this model, the learning phase was attributed to the first 29 cases, while the subsequent 73 cases constituted the mastery phase. In the mastery phase, operative time and intraoperative blood loss were significantly reduced compared to the learning phase(P<0.05). However, there were no statistically significant differences between the two phases in the incidence of intraoperative or postoperative complications(including organ injury, lymphocysts, infections, and ureteral stenosis)(P>0.05). Conclusion CUSUM analysis showed that the surgeon became technically stable after performing around 29 cases. As the learning curve transitioned from the growth phase to the mastery phase, the operative efficiency improved, with shorter surgery times and reduced blood loss. Meanwhile, the rates of intraoperative and postoperative complications remained comparable.

    Objective To investigate the dynamic changes in the endometrial microenvironment before and after frozen embryo transfer(FET)in patients with recurrent implantation failure(RIF), analyze their impact on pregnancy outcomes. Methods This prospective study enrolled 80 patients with RIF(RIF group)and 80 patients undergoing their first FET without RIF(control group)from March 2022 to April 2024. Serum levelsfollicle-stimulating hormone(FSH)and anti-Müllerian hormone(AMH)were measured upon admission. Changes in endometrial microenvironment were evaluated by quantifying cytokines, including vascular endothelial growth factor(VEGF), interleukin-1β(IL-1β), transforming growth factor-β1(TGF-β1), and interferon-γ(IFN-γ), in uterine cavity fluid before and after embryo transfer. Pregnancy outcomes, including biochemical pregnancy, clinical pregnancy, miscarriage rate, and live birth rate, were compared between the two groups. Univariate and multivariate analyses were conducted to identify independent risk factors influencing clinical pregnancy in RIF patients. Results Prior to embryo transfer, levels of IL-1β, TGF-β1, and IFN-γ were significantly higher in the RIF group than in the control group(P<0.05). Post-transfer, VEGF and TGF-β1 levels in the RIF group were significantly lower than those in the control group(P<0.05), whereas IL-1β and IFN-γ levels were significantly elevated(P<0.05). The RIF group also exhibited significantly lower clinical pregnancy and live birth rates compared to the control group(P<0.05). Both univariate and multivariate regression analyses indicated that FSH, AMH, post-transplantation IL-1β, and IFN-γ were significant independent risk factors affecting clinical pregnancy in RIF patients(P<0.05). Conclusion Patients with RIF demonstrate an immune-inflammatory imbalance in the endometrial microenvironment. Serum FSH and AMH levels, as well as post-transfer IL-1β and IFN-γ levels, serve as independent predictors of FET pregnancy outcomes.

    Objective To explore the value of the bronchodilation test(BDT)in assessing the severity of obstruction in the different degrees of pulmonary function obstruction. Methods This retrospective cohort study included 371 patients(202 males, 169 females)diagnosed with asthma at the Department of Respiratory and Critical Care Medicine, between January 1, 2022, and December 31, 2024. Based on baseline FEV1/FVC%(forced expiratory volume in one second to forced vital capacity ratio)and FEV1%(forced expiratory volume in one second)predicted values, patients were stratified into three groups: the mild group(FEV1%≥70%, n=201), the moderate group(FEV1% being 50%-69%, n=93), and the severe group(FEV1%<49%, n=77). All patients underwent the BDT(inhaled salbutamol 400 μg), and lung function parameters(FEV1, FVC, FEV1/FVC%)were recorded before and after BDT. Results Positivity rates were significantly higher in the moderate(80.6%)and severe(79.2%)groups compared to the mild group(36.8%)(χ2=48.865,P<0.001; χ2=40.077, P<0.001). The patients in the mild, moderate and severe groups were 50(37, 60), 56(46, 65.5), and 53(44, 63)years old, respectively, with a statistically significant difference among groups(H=7.202, P=0.027). The cohort comprised 54.4% males and 45.6% females, with no statistically significant difference in sex distribution(χ2=5.904, P=0.052). In the mild group, the improvement in FEV1(190 mL )was significantly greater that that in FVC(130 mL), Z=-4.015, P<0.001. In the severe group, the improvement in FVC(340 mL)was significantly greater than that in FEV1(200 mL),Z=-4.297, P<0.001. After the bronchodilation, FEV1/FVC% increased significantly in both the mild and moderate groups(P<0.01). The FEV1/FVC% decreased in the severe group(P<0.001). Conclusion Compared with patients with mild asthma-related airway obstruction, those with moderate and severe obstruction had higher BDT positivity rates and were older. In patients with mild to moderate obstruction, the dilation test primarily results in improvement in FEV1, whereas patients with severe obstruction show significant improvement in FVC.

    Objective To analyze the clinical characteristics and prognosis of Clostridium difficile infection(CDI)in children of different age groups and to explore risk factors for disease recurrence. Methods Clinical data from 63 children with initial CDI admitted to Childrens Hospital of Shandong University from January 2019 to December 2024 were retrospectively analyzed. Patients were divided into infant group(n=29,<3 years)and child group(n=34,3-12 years). Based on post-treatment recurrence, they were further categorized into recurrence group(n=11)and non-recurrence group(n=52). Employing statistical methods such as the Mann-Whitney U test and χ2 test, this study compared clinical data between two groups, summarized clinical and endoscopic characteristics, and identified risk factors for CDI recurrence through binary logistic regression analysis, with the predictive value of these factors for recurrence evaluated using receiver operating characteristic(ROC)curve analysis. Results Diarrhea and hematochezia were most common in infant group, while diarrhea, abdominal pain, and hematochezia predominated in child group. The incidence of abdominal pain(73.52 % vs. 34.48%)and erythrocyte sedimentation level [7.00(3.75,10.25)mm/h vs. 3.00(2.00,5.00)mm/h]were significantly higher in child group than infant group(P<0.05). All patients underwent colonoscopy. The colonoscopy positivity rate was 62.06% in infant group(predominantly mild), and 64.70% in child group(predominantly moderate). The infant group exhibited a lower degree of endoscopic severity compared to the child group(P<0.05). Patients received single or combined anti-CDI therapy. At 2-month follow-up, there was no significant difference in recurrence rates(17.24% vs. 17.65%)between two groups(P>0.05). Further analysis of recurrence(11 cases)and non-recurrence(52 cases)groups showed higher rate of inflammatory bowel disease(36.36% vs. 1.92%), higher white blood cell count[(12.72±2.44)×109/L vs.(8.89±3.15)×109/L], higher C-reactive protein[11.49(7.31,13.67)mg/L vs. 3.20(1.56,3.65)mg/L], higher fecal calprotectin [341.90(226.80,431.00)μg/g vs. 89.30(29.03,183.28)μg/g] levels in recurrence group(P<0.05)and lower serum prealbumin [(139.00±26.87)mg/L vs.(170.70±46.27)mg/L] in recurrence group(P<0.05). Binary logistic regression identified high fecal calprotectin(OR=1.009, 95%CI:1.001-1.017)was anindependentrisk factor for recurrence in children with CDI. ROC curve analysis demonstrated that fecal calprotectin predicted recurrence with an area under the curve of 0.886, a sensitivity of 0.727, a specificity of 0.942, and an optimal cut-off value of 300.30 μg/g. Conclusion Clinical symptoms and inflammatory markers of CDI vary minimally between age groups, but colonoscopy severity differs. High fecal calprotectin may be an independent risk factor for recurrence, warranting clinical attention.

    Objective To explore the impact of greater omentum repositioning after laparoscopic sleeve gastrectomy(LSG)on reducing postoperative nausea and vomiting(PONV). Methods A retrospective cohort study was conducted to collect the perioperative clinical data of 62 obese patients who underwent LSG in the Department of Gastrointestinal Surgery, The Second Qilu Hospital of Shandong University from January 2023 to January 2024. Among them, 30 patients underwent greater omentum repositioning after LSG(reduction group), and 32 patients only had the gastric incisions sutured and reinforced(control group). The preoperative baseline data and perioperative data of the patients were collected. The frequency scores of PONV, visual analogue scale(VAS)scores, and verbal descriptive scale(VDS)scores between the two groups of patients postoperatively were compared. Results There was no statistically significant differences in surgical duration, reinforcement suture time, and intraoperative blood loss between the two groups(P>0.05). Within 0-12 hours, 12-24 hours, and 24-72 hours after surgery, the frequency score, VAS score, and VDS score of PONV in the reduction group were higher than those in the control group(P>0.05). Conclusion Reduction of the greater omentum during LSG may decrease the occurrence and intensity of PONV in patients.

    Objective To investigate the causal associations between commonly used antihypertensive and lipid-lowering drugs and prevalent ocular diseases in East Asian and European populations using drug-target Mendelian randomization(MR). Methods This cross-ancestry drug-target MR study utilized publicly available genome-wide association study(GWAS)summary data from the GWAS Catalog. Five classes of antihypertensive drugs, including angiotensin-converting enzyme inhibitors(ACEIs), angiotensin II receptor blockers(ARBs), β-blockers(BBs), calcium channel blockers(CCBs), and thiazide diuretics(TDs), and three classes of lipid-lowering drugs, including 3-hydroxy-3-methylglutaryl-CoA reductase(HMGCR)inhibitors, proprotein convertase subtilisin/kexin type 9(PCSK9)inhibitors, and Niemann–Pick C1-like 1(NPC1L1)inhibitors were selected as exposures. Six common ocular diseases(senile cataract, glaucoma, dry eye syndrome, visual impairment, presbyopia, and myopia)were defined as outcomes. Inverse variance weighted(IVW)was employed as the primary analytical method, supplemented by seven additional MR methods for findings with statiscauy significant correlation. Sensitivity analyses were conducted using Cochrans Q test, MR-Egger intercept test, and leave-one-out analysis. Results In East Asian populations, ACEIs were causally associated with increased risks of myopia(OR=1.024, 95%CI: 1.010-1.038, PFDR=0.002), senile cataract(OR=1.022, 95%CI: 1.019-1.024, PFDR<0.001), and glaucoma(OR=1.017, 95%CI: 1.011-1.023, PFDR<0.001); BBs were associated with reduced risk of senile cataract(OR=0.994, 95%CI: 0.989-0.999, PFDR=0.034); PCSK9 inhibitors were associated with reduced risks of presbyopia(OR=0.993, 95%CI: 0.986-0.997, PFDR=0.003)and visual impairment(OR=0.996, 95%CI: 0.992-0.999, PFDR=0.048). In European populations, ACEIs were associated with increased glaucoma risk(OR=1.088, 95%CI: 1.029-1.152, PFDR=0.016); HMGCR inhibitors were associated with increased senile cataract risk(OR=1.194, 95%CI: 1.049-1.359, PFDR=0.022); PCSK9 inhibitors were associated with increased risks of dry eye syndrome(OR=1.106, 95%CI: 1.039-1.176, PFDR=0.004)and presbyopia(OR=1.082, 95%CI: 1.024-1.145, PFDR=0.017), but with reduced glaucoma risk(OR=0.892, 95%CI: 0.822-0.968, PFDR=0.018); NPC1L1 inhibitors were associated with reduced glaucoma risk(OR=0.706, 95%CI: 0.579-0.861, PFDR=0.002). Conclusion ACEIs may increase risks of certain ocular diseases in both East Asian and European populations. BBs may reduce senile cataract risk in East Asians. HMGCR inhibitors may increase cataract risk in Europeans, while NPC1L1 inhibitors may reduce glaucoma risk in Europeans. The effects of PCSK9 inhibitors on ocular diseases exhibit ethnic differences.

    Objective To analyze the changes in operational efficiency of secondary public general hospitals in Shandong Province, compare the efficiency differences among hospitals in different regions(the Provincial Capital Economic Circle, the Jiaodong Economic Circle, and the Lunan Economic Circle)of Shandong, and provide policy references for the differentiated development of secondary public general hospitals. Methods Panel data of secondary public general hospitals from 16 prefecture-level cities(Laiwu City was merged into Jinan City in 2019)and the three economic circles(the Provincial Capital Economic Circle, the Jiaodong Economic Circle, and the Lunan Economic Circle)in Shandong Province from 2014 to 2023 were collected. Input and output indicators were identified, and the Global-Malmquist index model based on the super-efficiency SBM model was used to analyze efficiency changes. Results From 2014 to 2023, the operational efficiency of secondary public general hospitals in Shandong Province increased from 0.948 to 1.320. The efficiency differences among the provincial capital, Jiaodong, and Lunan economic circles were small from 2014 to 2017 but became significant from 2018 to 2023. Among the 16 prefecture-level cities(excluding Laiwu), 15 showed an upward trend in operational efficiency, accounting for 93.75% of the total. Conclusion The operational efficiency of secondary public general hospitals in Shandong Province shows an upward trend but with large fluctuations. Efficiency is more significantly affected by technological changes. There are problems such as unbalanced development of regional technical efficiency and insufficient capacity in responding to major public health events. It is necessary to implement differentiated development strategies such as technological and institutional innovation and scale adjustment to promote the high-quality development of hospitals.

    Objective To systematically analyze the structural characteristics and collaborative logic of Chinas proactive health policy texts, identify existing problems and optimization directions, and provide references for improving the proactive health policy system and enhancing governance efficiency. Methods Using Nvivo 15 software, 50 proactive health policy texts issued at the central level from 2016 to 2024 were coded and analyzed. A three-dimensional analytical framework based on policy instruments, stakeholders, and policy goals was constructed, and content analysis was employed to conduct univariate descriptive statistics and multidimensional cross-analysis. Results In the policy instrument dimension, supply-side(46.76%)and environmental(35.49%)instruments dominated, while demand-side instruments were relatively scarce(17.75%). In the stakeholder dimension, the government(49.08%)occupied a dominant position, with non-governmental organizations severely under-involved(1.74%); the remaining stakeholders, in descending order of participation frequency, were the public(21.21%), healthcare institutions(17.52%), enterprises(5.53%), and research institutions and universities(4.92%). Policy goals were primarily concentrated on optimizing health services(57.14%)and improving public health(29.03%), with relatively weak policy support for accelerating health technology innovation(7.68%), developing the health industry(3.53%), and reducing the medical burden(2.61%). Cross-analysis revealed structural mismatches among policy instruments, stakeholders, and policy goals. Conclusion Chinas proactive health policies exhibit structural characteristics of being supply-driven, government-centered, and service-prioritized. It is recommended to optimize the policy instrument mix by strengthening demand-side instruments and rigid constraints; establish multi-stakeholder collaborative mechanisms to stimulate market and social vitality; and rebalance policy goal prioritization by addressing disadvantages in areas such as medical burden reduction, thereby advancing the proactive health policy system toward more balanced, efficient, and sustainable development.
    Research progress on the mechanism of lncNEAT1 in regulating cellular oxidative stress via the ceRNA network

    Cellular oxidative stress plays critical roles in regulating key pathophysiological processes, including cell proliferation, inflammatory responses, and programmed cell death(e.g., apoptosis, ferroptosis, and autophagy). Recent studies have revealed that the long non-coding RNA nuclear paraspeckle assembly transcript 1(lncNEAT1)serves a pivotal function in cellular stress responses. The expression of lncNEAT1 is induced under oxidative stress; in turn, it modulates oxidative stress levels via molecular mechanisms such as the competitive endogenous RNA(ceRNA)pathway. This bidirectional regulatory interplay constitutes a pivotal link in disease development and progression. LncNEAT1 exerts a dual role in regulating redox homeostasis, either exacerbating or alleviating effects depending on the cell type and pathological context. This review outlines how oxidative stress regulates lncNEAT1 expression and details the mechanisms by which lncNEAT1 functions as a ceRNA to sponge microRNA(miRNA), thereby modulating oxidative stress and cellular damage. These mechanisms include regulating reactive oxygen species(ROS)production, modulating the activity of key transcription factors(e.g., Nrf2, NF-κB, STAT3), and interfering with glutathione(GSH)synthesis. A deeper insight into the regulatory network between lncNEAT1 and oxidative stress is expected to provide novel strategies for elucidating pathogenesis, identifying diagnostic biomarkers, and developing targeted therapies for oxidative stress-related diseases affecting the cardiovascular, cerebrovascular, nervous, and reproductive systems.

    Digitalization and artificial intelligence are two important branches of computer science. In recent years, their applications in the field of dentistry have become increasingly widespread due to the rapid development of information technology. Pediatric dentistry involves multiple disciplines and there are varying oral conditions among children of different ages. Furthermore, childrens cooperation in oral disease treatment is relatively low, which makes clinical work more difficult. Digitalization and artificial intelligence technologies are gradually becoming established in the field of pediatric dentistry. In pediatric dental imaging, deep learning models can be used to assess dental age and detectabnormalities in the number and position of teeth. With regard to pediatric dental diseases, artificial intelligence can help with the screening and detection of tooth decay, the diagnosis of maxillofacial deformities in adolescents, and the design of orthodontic treatment plans. AI can also enhance pediatric dental behavior management and assess childrens oral health status. While ensuring the effectiveness of treatment, it provides children with comfortable, personalized, and highly humane treatment plans, which is of great clinical importance in improving the efficiency of diagnosis and treatment.
