By analyzing the current status of randomized controlled trials （RCTs） on functional dyspepsia （FD） and irritable bowel syndrome （IBS） comorbidity， we identified several critical issues which include insufficient repor-ting of FD and IBS subtypes， inadequate risk assessment of drug combination， lack of composite， objective， and long-term outcomes， and weak evidence support for clinical practice guidelines. It is suggested that future clinical research on FD-IBS comorbidity should further strengthen the application of real-world studies. The use of composite outcomes and long-term follow-up is recommended to improve the quality of evidence， while greater attention should be paid to patients' preferences and self-management to enhance the applicability of findings. Based on the existing issues in clinical studies of traditional Chinese medicine （TCM） for FD-IBS comorbidity， we propose to consolidate the foundation of TCM-specific efficacy evaluation to better reflect the advantages of syndrome differentiation and treatment， optimize real-world study designs to better support clinical decision- making， and introduce intelligent objective evaluation technologies to improve the objectivity and accuracy of TCM clinical efficacy assessment.

Animal model research on spleen and stomach diseases in traditional Chinese medicine （TCM） is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present， studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome， liver constraint syndrome， and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome， and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases， including chronic gastritis and gastric precancerous lesions， gastroesophageal reflux disease， functional dyspepsia， inflammatory bowel disease， irritable bowel syndrome， functional constipation， and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic， precise， and integrative development， and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

Objective:To construct a risk prediction model for early post-injury respiratory failure in patients with traumatic cervical spinal cord injury (TCSCI) and validate its efficacy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 393 TCSCI patients admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from January 2020 to October 2024, including 294 males and 99 females, aged 18-82 years [59(45, 72)years]. Among them, 76 patients had respiratory failure (19.3%). The patients were randomly divided into the training set ( n=275) and validation set ( n=118) at a ratio of 7∶3. According to the presence of respiratory failure within one week after admission, 275 patients in the training set were divided into respiratory failure group ( n=53) and non-respiratory failure group ( n=222). The demographic data, injury characteristics, laboratory test results, and imaging findings of the patients were collected. Risk factors were determined through univariate analysis and multivariate Logistic regression analysis and a nomogram prediction model was constructed. The area under the receiver operating characteristic (ROC) curve (AUC) and Hosmer-Lemeshow test were used to evaluate the discrimination and calibration of the model. Decision curve analysis (DCA) was plotted to evaluate the clinical effectiveness of the prediction model. Results:The results of the univariate analysis showed that there were significant differences in history of respiratory diseases, causes of injury, Glasgow coma scale (GCS), American Spinal Injury Association (ASIA) classification, ASIA-motor score (AMS), injury severity score (ISS), clinical pulmonary infection score (CPIS), hypoproteinemia and cervical vertebra fracture and dislocation between the respiratory failure group and non-respiratory failure group in the training set ( P<0.05). The results of multivariate Logistic regression analysis indicated that GCS, ASIA classification, CPIS, and hypoproteinemia were independent risk factors for early post-injury respiratory failure in TCSCI patients ( P<0.05). Based on the above four variables, a Logistic regression equation was constructed: Logit( P)=2.361-0.675×ASIA classification+0.419×CPIS-0.358×GCS+0.854×hypoproteinemia. In the prediction model established based on this equation, the AUC was 0.96 (95% CI 0.94, 0.99) in the training set and 0.89 (95% CI 0.82, 0.96) in the validation set. In the calibration curves of the training set and validation set, the prediction curve and reference curve were approximately overlapping, with the average absolute errors of 0.04 and 0.03. DCA results demonstrated that both the training and validation sets exhibited positive net benefits when threshold probabilities fell within ranges of 0%-78% and 0%-87%, respectively. Conclusion:The risk prediction model for early post-injury respiratory failure in TCSCI patients based on GCS, ASIA classification, CPIS and hypoproteinemia has good predictive efficacy and clinical practicability.

Objective The study aimed to investigate the predictive efficacy of contrast-enhanced ultrasound combined with telomerase reverse transcriptase(TERT)promoter mutation in constructing nomogram model for the prediction of concomitant cervical lymph node metastasis(CLNM)in papillary thyroid microcarcinoma(pTMC).Methods A total of 202 patients with pTMC who underwent partial or total thyroidectomy+lymph node dissection at our hospital from January 2021 to March 2024 were selected.Then,they were divided into the CLNM group(97 patients)and the non-CLNM group(105 patients)according to whether they had concomitant CLNM on postoperative pathological examination.General data and ultrasound(conventional ultrasound and contrast-enhanced ultrasound)characteristics were collected from all patients with pTMC,and Sanger sequencing was used to detect TERT promoter mutations.The influencing factors of pTMC complicated by CLNM were analyzed by single-factor and multifactorial unconditional logistic regression;the nomogram model of pTMC complicating CLNM with contrast-enhanced ultra-sound combined with TERT promoter mutation was constructed by RStudio 4.4.1 software,and the consistency and net benefit of the nomogram model were evaluated by using calibration curves,decision curves,and C-indexes,and the Hosmer-Lemeshow test for goodness of fit of the nomogram model;The predictive efficiency of the nomogram model constructed by combining contrast-enhanced ultrasound and TERT promoter mutation for pTMC complicated by CLNM was evaluated by plotting receiver operating characteristic(ROC)curves using MedCalc22.023 software.Results After postoperative pathological examination,the incidence of CLNM in 202 patients with pTMC was 48.02%(97/202).Univariate analysis showed that thyroglobulin antibodies,number of lesions,aspect ratio,micro-calcifications,enhancement time,enhancement mode,enhancement intensity,capsular continuity,and TERT promoter mutations were associated with pTMC complicating CLNM(P<0.05).Multifactorial unconditional logistic regression showed that multifocal tumours(OR=3.487,95%CI:1.641～7.406,P=0.001),microcalcifications(OR=4.484,95%CI:2.113～9.516,P<0.001),equal or high enhancement(OR=3.187,95%CI:1.460～6.957,P=0.004),disruption of peritoneal continuity(OR=2.201,95%CI:1.051～4.608,P=0.036),and TERT promoter mutation positivity(OR=4.460,95%CI:2.132～10.103,P<0.001)were the independent risk factors for pTMC complicating CLNM.A contrast-enhanced ultrasound combined TERT promoter mutation nomogram model was constructed based on independent risk factors for pTMC complicating CLNM[Logit(p)=-4.486+1.350×number of foci+1.399×microcalcifications+2.124×intensity of enhancement+1.524×capsular continuity+2.175×TERT promoter mutations].The C-index of this nomogram model was 0.899(95%CI:0.893～0.905),the calibra-tion curve alignment was close to the ideal curve,the decision curve was higher than the two extreme curves,and the Hosmer-Lemeshow test showed a P>0.05.The ROC curve analysis showed that the nomogram model constructed with contrast-enhanced ultrasound combined with TERT promoter mutations predicted CLNM in pTMC with an area under the curve of 0.899.This was significantly higher than the area under the curves for contrast-enhanced ultra-sound alone(0.857)and TERT promoter mutations alone(0.697)(P<0.05).Conclusion The contrast-enhanced ultrasound combined with TERT promoter mutations to construct a nomogram model has high predictive efficiency for pTMC complicating CLNM.

Objective This study aimed to investigate how β-glucosidase(GBA)knockdown affects malignant progression in cisplatin(DDP)-resistant ovarian cancer(OC)cells and the role of the EGFR signaling pathway.Methods The A2780/DDP cells were categorized into four groups,with one of them serving as blank control(Con)group,si-NC group(transfected with negative control si-NC),si-GBA group(transfected with si-GBA),and NSC 228155 group(transfected with si-GBA and treated with 2 μmol/L NSC 228155).The protein expression levels of GBA,E-cadherin,N-cadherin,Vimentin,EGFR,p38 mitogen-activated protein kinase(p38 MAPK),phospho(p)-p38 MAPK,extracellular regulated protein kinase(ERK)and p-ERK were detected through Western blot.The relative expression of GBA was evaluated through reverse transcription quantitative polymerase chain reaction.The proliferation activity,migration,and invasion potential were evaluated using cell counting kit-8(CCK-8),plate clone formation,cell scratch healing,and Transwell migration assays.Thirty-six nude mice were divided into six groups(six mice per group):blank control(injected with normal saline),blank control+DDP(treated with DDP),negative control(injected with A2780/DDP cell suspension transfected with si-NC),negative control+DDP(injected with A2780/DDP cell suspension transfected with si-NC and treated with DDP),knockdown(injected with A2780/DDP cell suspension transfected with si-GBA),and knockdown+DDP groups(injected with A2780/DDP cell suspension transfected with si-GBA and treated with DDP).The tumor volume and weight of nude mice were evaluated.Results The relative protein and mRNA expression levels of GBA were significantly higher in the A2780/DDP group than in the A2780 group(P＜0.05).Compared with estimates in the Con and si-NC groups,the proliferation activity,number of cloned cells,scratch repair rate,and number of transmembrane cells in the si-GBA group were significantly lower(P＜0.05).The abundance of E-cadherin expression exhibited a notable elevation(P＜0.05),and expression levels of Vimentin,N-cadherin,and EGFR as well as the p-p38 MAPK/p38 MAPK and p-ERK/ERK ratios were significantly decreased(P＜0.05).The proliferation activity,number of cloned cells,scratch repair rate,and the count of transmembrane cells and the expression level of E-cadherin in the NSC 228155 group were markedly higher and lower,respectively,than those in the si-GBA group(P＜0.05),and the expression levels of Vimentin,N-cadherin,and EGFR as well as the ratios of p-p38 MAPK/p38 MAPK and p-ERK/ERK were significantly increased(P＜0.05).In the nude mouse xenograft study,the tumor size and mass in the blank control+DDP group were notably smaller and lighter,respectively,compared to those in the blank control group(P＜0.05).The tumor volume and weight were significantly lower in the negative control+DDP group than in the negative control group(P＜0.05),significantly lower in the knockdown+DDP group than in the knockdown group(P＜0.05),moreover,they were markedly reduced in the knockdown group in comparison to both the blank control and negative control groups(P＜0.05).Compared with those in the blank control+DDP and negative control+DDP groups,the tumor volume and weight in the knockdown+DDP group were significantly reduced(P＜0.05).Conclusions GBA knockdown suppresses the proliferation,migration,and invasion of DDP-resistant OC cells significantly as well as the growth of subcutaneous xenografts derived from A2780/DDP cells in nude mice.These effects may be mediated through the inhibition of the EGFR/MAPK/ERK signaling pathway.

Objective:To explore the application effect of the BOPPPS[bridge-in(B), objective(O), pre-assessment(P), participatory learning(P), post-assessment(P), Summary(S) ]model combined with scenario-based teaching in out-of-school first aid training for school-aged children, aiming to offer insights for relevant educational practices.Methods:A quasi-experimental study was conducted. Using cluster sampling, 131 school-aged children participating in Wuhan first aid summer camp from July to August 2024 were selected as participants. Among them, 65 children enrolled in July 2024 were assigned to the control group and received training using traditional teaching methods, while 66 children enrolled in August 2024 were assigned to the experimental group and underwent training designed with the BOPPPS model integrated with scenario-based teaching according to the time of entry into the camp. After the training, theoretical exam scores, learning process evaluations, and training satisfaction were compared between the two groups.Results:The control group included 31 boys and 34 girls, aged (9.32 ± 1.83) years; the experimental group included 34 boys and 32 girls, aged (9.71 ± 1.73) years. After the intervention, the total scores of theoretical examination, learning process evaluation, and training satisfaction in the experimental group were (90.27 ± 4.41), (42.79 ± 1.39), and (21.43 ± 2.41) points, respectively, which were higher than those in the control group (82.05 ± 6.29), (38.85 ± 1.91), and (19.54 ± 3.02) points, and the differences were statistically significant ( t=6.94, 3.15, 4.16, all P<0.05). Conclusions:This out-of-school first aid training for school-aged children leveraged the professional expertise of a tertiary grade A hospital′s pediatric department. The integration of the BOPPPS model with scenario-based teaching effectively enhanced the first aid competencies of school-aged children and improved their satisfaction with the training.
