ObjectiveBased on literature data mining， this study explores the modeling elements of diarrhea-predominant irritable bowel syndrome （IBS-D） animal models in China and abroad， providing references and suggestions for improving modeling methods and evaluation indicators. MethodsRelevant literature on IBS-D animal experiments from 2014 to 2024 was retrieved through computer searches in databases such as China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， Chinese Medical Journals Full-text Database， and PubMed. Information on experimental animal species， gender， body weight， modeling methods， modeling periods， intervention controls， modeling standards， and detection indicators was organized. Microsoft Excel 2021 software was used to establish a database and perform statistical analysis to examine the characteristics of IBS-D animal models. ResultsA total of 398 articles that met the inclusion criteria were reviewed. The IBS-D animal models were predominantly established using SD rats， Wistar rats， and C57BL/6 mice. Male animals were more commonly used， with rats typically aged 6-8 weeks and mice aged 4-6 weeks. In terms of interventions， piverium bromide was the main Western medicine， Tongxieyaofang was the primary Chinese medicine， and electroacupuncture was the primary acupuncture method. Among the modeling methods， the multi-factor combined composite modeling approach was the most common. Modeling periods were mainly concentrated between 1-14 days and 15-30 days. The success criteria for modeling were mainly evaluated based on the animal's general condition， fecal appearance， visceral sensitivity， gastrointestinal motility， behavior， and pathology. Detection indicators included apparent indexes， pathological markers， biochemical indicators， oxidative stress， brain-gut peptides， neurotransmitters， inflammatory factors， immune function， intestinal permeability， autophagy， apoptosis， proteins related to relevant signaling pathways， intestinal microbiota and its metabolites， etc. ConclusionThere are various methods for establishing IBS-D animal models， but no unified and universally accepted method has been established. The operation of the same modeling methods and the evaluation standards of the models vary across studies. Based on the results of data mining， the authors suggest that the multi-factor combined composite modeling approach most closely reflects the pathophysiological processes of IBS-D， better simulating the complex clinical symptoms of IBS-D patients， such as abdominal pain and diarrhea， and has a high degree of clinical relevance. This method is relatively recommended. While animal models in general align with Western medicine standards， models incorporating traditional Chinese medicine （TCM） syndromes are relatively few. Therefore， one of the future directions for research is to establish IBS-D animal models that meet the combined clinical disease and syndrome requirements of both Western and Chinese medicine.

Objective To explore the efficacy of endoscopic therapy for esophageal and gastric variceal bleeding(EGVB),investigate the risk factors for rebleeding within 1 year,and establish a predictive model accordingly.Methods A retrospective study was conducted using the clinical and follow-up data of 120 EGVB patients who underwent endoscopy at our hospital between January 2021 and December 2022.The efficacy of endoscopic therapy was analyzed,and the patients were divided into a bleeding group and a non-bleeding group based on whether rebleeding occurred within 1 year after treatment.The factors influencing rebleeding within 1 year after treatment were analyzed,and a predictive model was established using logistic regression analysis.The model's goodness of fit was evaluated using the Hosmer-Lemeshow test,and its clinical value was analyzed using the receiver operating characteristic(ROC)curve.Results The hemostasis success rate within 72 hours after endoscopic therapy was 100％in all 120 patients.Four weeks after endoscopic treatment,endoscopic reexamination showed that the complete and partial disappearance rate of varices was 75.83％(91/120),with rebleeding occurring in 10 cases(8.33％).There were 34 cases(28.33％)of cumulative rebleeding at 6 months and 63 cases(52.50％)at 1 year after endoscopic therapy.Nine patients(7.50％)died within 1 year after endoscopic therapy,all of whom were rebleeding cases.A total of 63 patients with rebleeding were included in the bleeding group,and 57 patients without rebleeding were included in the non-bleeding group.Serum sodium＜135 mmol/L(odds ratio[OR]=3.837,95％confidence interval[CI]:1.095-13.445),Child-Pugh grade C(OR=3.835,95％CI:1.137-12.935),esophageal varices degree G3(OR=5.113,95％CI:1.565-16.707),and main portal vein diameter＞12 mm(OR=5.964,95％CI:2.295-15.497)were identified as risk factors of rebleeding within 1 year after endoscopic therapy in EGVB patients(P＜0.05).The risk prediction model for rebleeding within 1 year after endoscopic therapy in EGVB patients was shown as P=1/{1+e[-(-3.815+1.345×serum sodium+1.344×Child-Pugh grade+1.786×main portal vein diameter+1.632×esophageal varices degree)]}.The Hosmer-Lemeshow x2 was 3.158(P=0.856).The area under the curve(AUC)for predicting rebleeding within 1 year after endoscopic therapy in EGVB patients was 0.815,indicating good predictive performance.Clinical validation showed that the model had an accuracy of 82.30％,with sensitivity and specificity being 81.03％and 83.63％,respectively.Conclusion Endoscopic therapy for EGVB achieves a high rate of acute bleeding control,but patients remain at risk of rebleeding.Rebleeding is associated with serum sodium＜135 mmol/L,Child-Pugh grade C,main portal vein diameter＞12 mm,and esophageal varices degree G3.The logistic regression model can effectively predict the probability of rebleeding within 1 year after endoscopic therapy.

Objective To investigate the effects of indirubatin derivative E804 on proliferation and migration of non-small cell lung cancer(NSCLC)A549 cells,and to elucidate the possible mechanism of Nrf2-HO-1/GPX4 pathway.Methods Lung cancer A549 cells were used as the cell model.The proliferation and migration of differ-ent specific inhibitors(Nec-1,CQ,Z-VAD,DFO,Fer-1 and Lip-1)in 0,10 μmol/L E804 and 10 μmol/L E804+groups were observed by MTT and cell scratch assay.The contents of reactive oxygen species(ROS)were de-tected by DCFH-DA fluorescence probe method,the contents of Fe2+were detected by colorimetric method,the contents of reduced glutathione(GSH)were detected by spectrophotometry,and the contents of malondialdehyde(MDA)were detected by micromethod.The expression levels of SLC7A11,Transferrin,GPX4,SLC40A1,Nrf2 and HO-1 were detected by Western blot in cells of 0,2.5,5 and 10 μmol/L E804 groups.Results Compared with the control group(0 μmol/L E804),2.5,5 and 10 μmol/L E804 significantly increased intracellular ROS,Fe2+and MDA levels,and decreased intracellular GSH content(P＜0.01).Meanwhile,the expression levels of SLC7A11,GPX4,SLC40A1,Nrf2 and HO-1 significantly decreased(P＜0.01),and the expression level of Transferrin increased(P＜0.05).Compared with the 10 μmol/L E804 group alone,the apoptosis inhibitor(Z-VAD)group and the ferroptosis inhibitor(DFO,Fer-1 and Lip-1)group could significantly reverse the inhibition of proliferation and migration of A549 cells by 10 μmol/L E804(P＜0.01).Conclution E804 can induce ferrop-tosis and inhibit the proliferation and migration of A549 cells,which may be related to the inhibition of Nrf2-HO-1/GPX4 pathway.

Objective To investigate the value of continuous monitoring of indocyanine green retention rate at 15 minutes(ICG-R15)combined with standard residual liver volume(SRLV)in predicting hepatic insufficiency after partial hepatectomy.Methods Clinical data and SRLV data were collected from 70 patients with hepatocellular carcinoma who were admitted to Department of Hepatobiliary Surgery,Tianjin First Central Hospital,from November 2016 to May 2017.According to the presence or absence of hepatic insufficiency after surgery,the patients were divided into good liver function group with 56 patients and hepatic insufficiency group with 14 patients.Based on preoperative liver function evaluation and contrast-enhanced CT scans,resected liver volume and residual liver volume were calculated,and three-dimensional reconstruction of the liver was performed.Intraoperative ultrasound localization was performed to determine the surgical regimen,and selective hepatic inflow occlusion or intermittent hepatic portal occlusion was selected based on intraoperative conditions.CUSA combined with BIPOLAR drip electric coagulation forceps were used for the partition of liver parenchyma.SRLV was calculated,and ICG-R15 was monitored continuously.The independent-samples t test was used for comparison of continuous data between two groups,and the chi-square test was used for comparison of categorical data between two groups;the area under the ROC curve(AUC)was used to investigate the accuracy in predicting hepatic insufficiency after surgery.A multivariate Logistic regression analysis was used to establish a predictive model for postoperative hepatic insufficiency,and diagnostic criteria were developed for SLRV combined with postoperative ICG-R15 dynamic monitoring in the diagnosis of postoperative hepatic insufficiency.Results There were significant differences between the two groups in ICG-R15 before surgery,immediately after surgery,and on days 3 and 5 after surgery,as well as significant differences in SRLV and Child class(all P＜0.05).The incidence rate of postoperative hepatic insufficiency increased with the increase in ICG-R15 before surgery,immediately after surgery,and on days 3 and 5 after surgery(all P＜0.001).Further comparison between two groups showed that there was a significant difference in the incidence rate of hepatic insufficiency between the ICG-R15＞20%group and the other two groups before surgery,immediately after surgery,and on days 3 and 5 after surgery(all P＜0.001),and there was a significant difference in the incidence rate of hepatic insufficiency between the ICG-R15＜10%group and the 10%≤ICG-R15≤20%group immediately after surgery(P＜0.001).ICG-R15 before surgery,ICG-R15 immediately after surgery,ICG-R15 on day 3 after surgery,and ICG-R15 on day 5 after surgery had an AUC of 0.790,0.857,0.855,and 0.870,respectively,in predicting postoperative hepatic insufficiency,and ICG-R15 immediately after surgery and on days 3 and 5 after surgery had a significantly larger AUC than ICG-R15 before surgery(all P＜0.05).The multivariate analysis showed that increases in SRLV and postoperative ICG-R15 dynamic monitoring(immediately after surgery and on days 3 and 5 after surgery)were independent risk factors for postoperative hepatic insufficiency,while increased body mass index before surgery was an independent protective factor(all P＜0.05).A multivariate Logistic regression predictive model was established and was used to predict hepatic insufficiency after surgery(immediately after surgery and on days 3 and 5 after surgery),and the ROC curve analysis showed that the model had an AUC of 0.963,0.967,and 0.967,respectively,in predicting hepatic insufficiency immediately after surgery and on days 3 and 5 after surgery(all P＜0.01).Diagnostic criteria were developed for SLRV combined with postoperative ICG-R15 dynamic monitoring in the diagnosis of postoperative hepatic insufficiency,i.e.,SLRV＞1 240 mL/m2,ICG-R15＞20%immediately after surgery,or ICG-R15＞25%on day 3 or 5 after surgery,and postoperative hepatic insufficiency could be diagnosed if a patient met any one criterion.These diagnostic criteria had a sensitivity of 100%,a specificity of 60.71%,and a conformity degree of 68.57%.Conclusion Continuous monitoring of ICG-R15 before and after surgery is of guiding significance for predicting postoperative hepatic insufficiency,and ICG-R15 on day 5 after surgery has the highest accuracy.SRLV combined with postoperative ICG-R15 dynamic monitoring can effectively predict the onset of hepatic insufficiency after hepatectomy and can guide clinicians to predict the onset of postoperative hepatic insufficiency in patients with liver cancer and perform clinical intervention as soon as possible.

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Leiomyomas are benign tumors that arise from smooth muscle cells and rarely involve the male genitourinary system. We reported a case of a patient who underwent radical orchiectomy for epididymal tumor. The postoperative pathological diagnosis was epididymal leiomyoma, and there was no recurrence after 9 months of follow-up.

Objective To study the gait characteristics of low back pain(LBP)pilots by three-dimensional gait analysis technique,and provide basic data for the development of targeted rehabilitation programs for LBP pilots.Methods From March 2017 to May 2018,35 LBP pilots were enrolled.The pilots wore sensors accurately and walked straightly for 15 steps.The OptiTrack three-dimensional gait analysis system was used to monitor space distance parameters and joint range of motion.Results The step width[(0.18±0.09)m],step speed[(0.95±0.21)m/s],left foot deflection angle(-4.31±9.64)°,left step length[(0.54±0.14)m],left single support phase time[(452.43±55.98)ms)],and standing phase time[(628.41±122.4)ms]in the LBP pilots were lower than those in the normal population.The right double support phase time was slightly shorter than the left side in the LBP pilots.In-toeing gait presented commonly in the LBP pilots.The right single support phase time[(455.84±51.06)ms]and the standing phase time[(674.59±202.32)ms]were prolonged.The step length on the right was compensatively increased and significantly higher than that on the left(P=0.012).The flexion(6.88±4.47)° and extension(-15.78±5.80)° of the right hip joint and the flexion of the right knee joint(32.03±5.26)° were weaker than those of normal population.Right knee hyperextension was common in LBP pilots.Conclusion In-toeing gait presents commonly in LBP pilots.Their step width,step speed,foot deflection angle,and step length are narrower than those of the normal population.The lower limbs are mainly characterized by reduced flexion of the hip and knee joints and hyperextension of the right knee.It is essential to take more targeted functional exercise to prevent and treat LBP in pilots.

Objective: To discuss the effects of acupuncture plus Tuina (Chinese therapeutic massage) in intervening the mental development, motor function, cerebral hemodynamics, and muscle tone in kids with spastic cerebral palsy (CP). Methods: A retrospective analysis was conducted on 87 kids with spastic CP. They were divided into a control group and an observation group based on their original treatment plan. Kids in the control group received symptomatic treatment, motor development therapy, and Tuina treatment. The observation group was additionally given acupuncture treatment. One month was taken as a treatment course. After six courses, the efficacy, change in muscle tone, mental development, gross motor function, fine motor function, and the systolic velocity (Vs), mean velocity (Vm), and pulsatility index (PI) of the anterior cerebral artery (ACA), middle cerebral artery (MCA), and posterior cerebral artery (PCA) were compared between the two groups. Results: After treatment, the muscle tone score dropped in both groups (P<0.05) and was significantly lower in the observation group than in the control group (P<0.05). The observation group achieved more significant efficacy than the control group (P<0.05). After the intervention, the mental development index (MDI), psychomotor development index (PDI), gross motor function measure (GMFM) score, and fine motor function measure (FMFM) score all increased in both groups (P<0.05) and were notably higher in the observation group than in the control group (P<0.05). After treatment, the Vs and Vm of the ACA, MCA, and PCA were markedly higher in the observation group than in the control group (P<0.05), and the observation group was significantly lower than the control group comparing the PI of the ACA, MCA, and PCA (P<0.05). Conclusion: Based on the symptomatic treatment and motor development therapy, Tuina and acupuncture treatment can effectively treat spastic CP children, manifesting as reducing muscle tone, boosting mental development, and improving motor function and cerebral hemodynamics.
