Objective To evaluate the efficacy and safety of a novel gastrointestinal mucosal elevation gel in vivo porcine model. Methods Eight healthy white pigs were selected, which were uesd to bump height evaluation (n=2) and safety evaluation (n=6). The sample (alimentary canal mucosa bump gel sample) and the control sample (disposable endoscopic submucosal filler of alimentary canal) were respectively injected into the submucosa of pig gastric antrum and gastric body. In the evaluation of elevation height, the morphology, persistence, and clinical safety of mucosal elevation were observed and recorded immediately and 30 minutes after injection. In safety evaluation, endoscopic mucosal resection was performed after injection, and the mucosal protrusion shape, product efficacy, and clinical safety were observed and recorded at immediate and 7-day time points. After observation, all animals were euthanized and tissue samples were collected and excised for histopathological evaluation. Results In elevation height evaluation, sample group showed a steep elevation immediately after surgery, exhibiting a more pronounced elevation morphology compared to control group (P=0.019). Only two (25%) sites of the elevation showed slight collapse in 30 minutes after surgery, and the durability notably increased compared to control group (8 all collapsed, P＜0.001). In safety evaluation, the average trauma area of sample group was 1.77 mm², which was significantly lower than control group (2.65 mm², P＜0.001). There was no statistical difference among average injection dose per unit area, surgical time per unit area, and en bloc resection rate. Sample group showed mild ulcers and only 1 (12.5%) site of mild bleeding at immediate time point after surgery. No bleeding, perforation, ulcer or edema was observed in sample group 7 days after surgery, and no statistical difference was identified compared to control group. Histopathological evaluation found that the gastric antrum and body tissues exhibited moderate injury and mild edema at immediate time point, accompanied by mild inflammatory cellular infiltration. At 7-day time point, gastric antrum tissues demonstrated moderate injury, mild edema and mild inflammatory cellular infiltration, with 1 (12.5%) site of tissues infected, while in gastric body tissues, no bleeding was observed, whereas moderate injury and mild edema were evident, accompanied by mild inflammatory cellular infiltration and 3 (37.5%) sites of tissues infected, all of which were not statistically different from control group. Conclusion The novel gastrointestinal mucosal elevation gel exhibited steep elevation morphology, long-lasting elevation height, and favorable efficacy and safety in preclinical animal trials, showing enormous clinical application potential.

Objective:To analyze the correlation between thymus dose-volume parameters and lymphopenia in patients with early-stage breast cancer (BC) receiving adjuvant radiotherapy (RT).Methods:Medical records of 54 patients with early-stage BC who received postoperative adjuvant RT in the Second Affiliated Hospital of Soochow University from January to December 2019 were retrospectively analyzed. Absolute lymphocyte counts (ALC) were collected at 1 month before (baseline) and weekly during RT. Lymphopenia was graded based according to the common terminology criteria for adverse events version 5.0 and nadir/baseline ALC was calculated. The thymus was delineated according to anatomical boundaries in the original RT planning system. Dosimetric parameters were obtained from the dose volume histograms. Stepwise multiple linear regression analysis was used to explore the factors associated with nadir/baseline ALC. The cutoff values of dosimetric parameters for predicting ≥grade 3 lymphopenia were obtained using the receiver operating characteristic (ROC) curve.Results:The proportion of 54 patients experiencing ≥ grade 3 lymphopenia was 38.9%. The median value of thymus volume, mean dose, V 5 Gy, V 10 Gy were 14.02 cm 3, 4.95 Gy, 36.18%, and 6.61%, respectively. Stepwise multiple linear regression analysis revealed that baseline ALC ( P=0.005), quadrant location ( P=0.005) and mean thymus dose ( P<0.001) were significantly associated with nadir/baseline ALC. ROC curve analysis indicated that the cutoff values of thymus mean dose, V 5 Gy and V 10 Gy for predicting ≥ grade 3 lymphopenia were 6.12 Gy, 35.2%, and 7.4%, respectively. Conclusions:Lymphopenia in early-stage BC patients is significantly correlated with high dosimetric parameters of the thymus during postoperative adjuvant RT. Thymus may be considered as an organ at risk during RT.

Background and Aims:Long noncoding RNA(lncRNA)nuclear-enriched abundant transcript 1(NEAT1)is an oncogenic lncRNA that promotes the progression of various cancers through the competing endogenous RNA(ceRNA)mechanism.Using the TargetScan database,we previously identified binding sites between NEAT1 and microRNA-124-3p(miR-124-3p),as well as between miR-124-3p and catenin beta-1(CTNNB1).Therefore,this study was conducted to investigate the expression of NEAT1,miR-124-3p,and CTNNB1 in pancreatic cancer and their interactions affecting pancreatic cancer cell functions.Methods:A dual-luciferase reporter assay was used to validate the relationships among NEAT1,miR-124-3p,and CTNNB1.The expression levels of NEAT1 and miR-124-3p,as well as CTNNB1 protein expression,were detected in pancreatic cancer tissues and adjacent normal tissues,as well as in pancreatic cancer PANC-1 cells and normal pancreatic epithelial H6C7 cells.PANC-1 cells were transfected with NEAT1 siRNA alone or co-transfected with a miR-124-3p inhibitor.After transfection,changes in PANC-1 cell biological functions,epithelial-mesenchymal transition related protein expression,and tumor growth ability in mice were assessed.Results:The dual-luciferase reporter assay confirmed the targeting relationships between NEAT1 and miR-124-3p,as well as between miR-124-3p and CTNNB1.NEAT1 and CTNNB1 expression levels were significantly upregulated,while miR-124-3p expression was downregulated in pancreatic cancer tissues(vs.adjacent tissues)and in PANC-1 cells(vs.H6C7 cells)(all P<0.05).NEAT1 siRNA transfection led to decreased NEAT1 and CTNNB1 expression and increased miR-124-3p expression in PANC-1 cells.However,co-transfection with a miR-124-3p inhibitor suppressed the expression changes in miR-124-3p and CTNNB1(all P<0.05).NEAT1 siRNA transfection significantly reduced PANC-1 cell proliferation,migration,and invasion,while promoting apoptosis.Additionally,E-cadherin protein expression was upregulated,whereas N-cadherin and vimentin protein expression were downregulated.Tumor growth in mice was also significantly inhibited(all P<0.05).These changes were attenuated upon co-transfection with the miR-124-3p inhibitor(all P<0.05).Conclusion:NEAT1 may act as a ceRNA by competitively binding to miR-124-3p,thereby attenuating miR-124-3p-mediated inhibition of CTNNB1.This leads to CTNNB1 upregulation,ultimately promoting the malignant biological behavior of pancreatic cancer cells.

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

Objective To explore early postoperative gait characteristics and clinical outcomes after total knee arthroplasty(TKA).Methods From February 2023 to July 2023,26 patients with unilateral knee osteoarthritis(KOA)were treated with TKA,including 4 males and 22 females,aged from 57 to 85 years old with an average of(67.58±6.49)years old;body mass in-dex(BMI)ranged from 18.83 to 38.28 kg·m-2 with an average of(26.43±4.15)kg·m-2;14 patients on the left side,12 pa-tients on the right side;according to Kellgren-Lawrence(K-L)classification,6 patients with grade Ⅲ and 20 patients with grade Ⅳ;the courses of disease ranged from 1 to 14 years with an average of(5.54±3.29)years.Images and videos of standing up and walking,walking side shot,squatting and supine kneeling were taken with smart phones before operation and 6 weeks after operation.The human posture estimation framework OpenPose were used to analyze stride frequency,step length,step length,step speed,active knee knee bending angle,stride length,double support phase time,as well as maximum hip flexion angle and maximum knee bending angle on squatting position.Western Ontario and McMaster Universities(WOMAC)arthritis index and Knee Society Score(KSS)were used to evaluate clinical efficacy of knee joint.Results All patients were followed up for 5 to 7 weeks with an average of(6.00±0.57)weeks.The total score of WOMAC decreased from(64.85±11.54)before op-eration to(45.81±7.91)at 6 weeks after operation(P＜0.001).The total KSS was increased from(101.19±9.58)before opera-tion to(125.50±10.32)at 6 weeks after operation(P＜0.001).The gait speed,stride frequency and stride length of the affected side before operation were(0.32±0.10)m·s-1,(96.35±24.18)steps·min-1,(0.72±0.14)m,respectively;and increased to(0.48±0.11)m·s 1,(104.20±22.53)steps·min-1,(0.79±0.10)m at 6 weeks after operation(P＜0.05).The lower limb support time and active knee bending angle decreased from(0.31±0.38)sand(125.21±11.64)° before operation to(0.11±0.04)s and(120.01±13.35)° at 6 weeks after operation(P＜0.05).Eleven patients could able to complete squat before operation,13 patients could able to complete at 6 weeks after operation,and 9 patients could able to complete both before operation and 6 weeks after operation.In 9 patients,the maximum bending angle of crouching position was increased from 76.29° to 124.11° before operation to 91.35° to 134.12° at 6 weeks after operation,and the maximum bending angle of hip was increased from 103.70° to 147.25° before operation to 118.61° to 149.48° at 6 weeks after operation.Conclusion Gait analysis technology based on artificial intelligence image recognition is a safe and effective method to quantitatively identify the changes of pa-tients'gait.Knee pain of KOA was relieved and the function was improved,the supporting ability of the affected limb was im-proved after TKA,and the patient's stride frequency,stride length and stride speed were improved,and the overall movement rhythm of both lower limbs are more coordinated.

ObjectiveTo elucidate the principles and methods of the Bayesian probabilistic linkage model， and to demonstrate the effect of applying the model in linking birth and death data. MethodsThrough the Shanghai birth and death registration system， data of 199 025 infants born in 2017 and 1 512 infants who died in 2017 and 2018 were collected. After cleaning the data， the data were divided into monthly blocks and fully linked. The Jaro-Winkler algorithm and Euclidean distance were employed to measure the similarity of fields for matching. A Bayesian probabilistic linkage model was constructed and the linking effect was evaluated using a confusion matrix. ResultsUsing the Bayesian probabilistic linkage model， the birth and death data of infants were effectively linked， revealing that 36.71% of infants who died in Shanghai were born outside the city， and the probability of infant death was 2.6‰. The confusion matrix of the test set showed a recall rate of 0.86， precision of 0.76， and an F-score of 0.81. ConclusionThe practical application of Bayesian probabilistic linkage demonstrates a good model performance， enabling the establishment of birth-death cohorts that more accurately reflect the true levels of infant mortality. Utilizing this technique to integrate data from different departments can effectively improve research efficiency in the field of public health.

Objective To explore the effect of transcranial direct current stimulation(tDCS)based on music therapy on insomnia. Methods From July,2023 to April,2024,70 patients with insomnia in the Fourth Affiliated Hospital of Soochow Univer-sity were randomly divided into control group(n=35)and observation group(n=35).Both groups accepted mu-sic therapy;moreover,the observation group accepted tDCS,and the control group accepted sham tDCS,for four weeks.They were assessed with Pittsburgh Sleep Quality Index(PSQI)total score and sub-score,Hamilton De-pression Scale 17-item(HAMD-17),Hamilton Anxiety Scale(HAMA),Chinese version of Stress Perception Scale(CPSS);and the relative power of resting-state electroencephalography(EEG)and mean blood flow veloci-ty(Vm)of each cerebral artery with transcranial Doppler were measured before and after treatment. Results Five cases dropped down in the control group,and four in the observation group.PSQI total score and sub-score,HAMD-17 score,HAMA score and CPSS score(|t|>3.503,P<0.01)in the observation group decreased after treatment,and were less in the observation group than in the control group(|t|>2.304,P<0.05),except sleep duration,sleep efficiency and CPSS scores.The relative power of δ and θ increased in the observation group,and decreased in α,β and γ(|t|>6.468,P<0.001),and were better in the observation group than in the control group(|t|>2.395,P<0.05).The Vm of each artery increased in the observation group(|t|>4.624,P<0.001),and were more in the observation group than in the control group(|t|>2.147,P<0.05). Conclusion tDCS based on music therapy may further improve sleep quality and EEG activity,increase cerebral blood flow velocity,and reduce adverse emotions in insomnia patients.

Objective To investigate the medication rules of tradition Chinese medicine for the treatment of ulcerative colitis(UC)at remission stage by data mining method,thus to provide reference for clinical prescription and medication.Methods The clinical research or medical case report of UC remission treated by Chinese medicine issued in CNKI,Wanfang Data and VIP from July 2000 to December 2022 were retrieved.Excel 2019 was used to analyze the frequency statistics,and the distribution of the nature,flavor and meridian tropism of the prescribed drugs in the included literature.Modeler 18.0 and SPSS Statistics 26.0 were used for association rules and cluster analysis,and Cytoscape 3.9.1 was used to construct the network diagram of the associated drugs.Results A total of 121 articles were included in the analysis,involving 167 drugs,of which 24 drugs were frequently used,mainly including Atractylodis Macrocephalae Rhizoma,Poria,Aucklandiae Radix,Coptidis Rhizoma,Codonopsis Radix,Paeoniae Radix Alba,Coicis Semen,Astragali Radix,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Angelicae Sinensis Radix,Citri Reticulatae Pericarpium,and Dioscoreae Rhizoma.According to the therapeutic actions,the drugs were mainly classified into deficiency-supplementing drugs,heat-clearing drugs,qi-regulating drugs,urination-promoting and dampness-percolating drugs,blood-stanching drugs,exterior-relieving drugs,interior-warming drugs,astringent drugs,dampness-resolving drugs,and blood-activating and stasis-resolving drugs.The medicinals were mainly warm,mild and cold in nature,and were sweet,bitter and pungent in flavor.Most of the drugs had the meridian tropism of the spleen,stomach,lung and liver.A total of 25 drug association rules were mined out,and five prescriptions were obtained after cluster analysis.Conclusion The Chinese medicine prescriptions for the treatment of UC remission usually deprive from the classical formulas such as Shenling Baizhu San,Sishen Pills,and Tongxie Yaofang.The compatibility of drugs reflects the thoughts of treating UC remission from the perspective of spleen,and embodies the therapies of strengthening the spleen and removing dampness,promoting qi and regulating blood,and focusing on tonifying ministerial fire and supporting yang in the later stage,which has the characteristics of treating both symptoms and root causes simultaneously by using multiple drugs through multiple methods.
