Objective To investigate the current status of pelvic floor muscle training(PFMT)adherence for preventing low anterior resection syndrome(LARS)in rectal cancer patients with prophylactic ostomy and analyze its influencing factors.Methods A total of 247 patients who underwent preventive stoma reversal surgery after sphincter-preserving rectal cancer resection between January 2024 and February 2025 at 22 tertiary hospitals in the Beijing-Tianjin-Hebei region were recruited in this study.Their clinical data were collected through a general information questionnaire,a LARS Knowledge-Attitude-Practice and Needs questionnaire,a PFMT Self-Efficacy Scale,and a PFMT Adherence Questionnaire.Univariate analysis,correlation analysis,LASSO regression,and random forest importance ranking were applied to screen the variables,and multiple linear regression analysis was conducted to analyze the significant variables.Results The overall PFMT adherence score was 14.52±4.18 among the 247 patients.The random forest algorithm identified 7 key predictors when the minimum error was achieved at a λ value of 2.293.The top 7 variables in importance ranking were PFMT self-efficacy,total knowledge-attitude-practice(KAP)score,education level,primary caregiver,tumor location,stoma reversal time,and chemoradiotherapy.Multiple linear regression analysis revealed that PFMT self-efficacy(P<0.001,β=0.007,95%CI:0.004～0.009),total KAP score(P<0.001,β=0.052,95%CI:0.035～0.070),stoma reversal time(P<0.030,β=-0.539,95%CI:-1.025～-0.053),and chemoradiotherapy(P<0.045,β=-0.451,95%CI:0.010～0.892)were significant related factors of PFMT adherence(P<0.05).Conclusion PFMT adherence for LARS prevention is at a moderate level in rectal cancer patients with prophylactic ostomy.Key factors such as PFMT self-efficacy,total KAP score,stoma reversal time,and chemoradiotherapy are significantly correlated with PFMT adherence.

Objective To investigate the relationship between the expression of absent in melanoma 2(AIM2)gene in peripheral blood peripheral blood mononuclear cell(PBMC)of patients with advanced gastric cancer(GC)and the intestinal flora and the efficacy of targeted therapy.Methods 83 patients with advanced GC who were treated from January to December 2023 were all given Trastuzumab/Nebuliumab combined with conventional chemotherapy for 4 weeks/course and 3 continuous courses of treatment to evaluate the efficacy of targeted therapy.The abundance of intestinal flora was analyzed using 16S rDNA sequencing technologies.Quantitative real-time PCR(qRT-PCR)was used to detect AIM2 mRNA expression levels in PBMC,which were divided into a high expression group and a low expression group according to the median digit.Pearson correlation analysis was used to investigate the relationship between AIM2 expression and the relative abundance of intestinal flora,the efficacy of targeted therapy and clinical features.Results At the phylum level,the relative abundance of Bacteroidetes(0.70±0.15)and Proteobacteria(0.71±0.21)in the high expression group of AIM2 was significantly lower than that in the low expression group(0.81±0.17,0.80±0.16),and the relative abundance of Firmicutes(0.73±0.12)was significantly higher than that in the low expression group(0.64±0.08),and the differences were statistically significant(t=3.108,2.210,4.061,all P＜0.05).At the genus level,the relative abundance of Bacteroides(0.13±0.02)in the high expression group of AIM2 was significantly lower than that in the low expression group(0.19±0.04),and the relative abundance of Enterococcus(0.31±0.08 vs 0.12±0.05)and Escherichia coli(0.18±0.04 vs 0.10±0.02)was significantly higher than that in the low expression group(0.12±0.05,0.10±0.02),and the differences were statistically significant(t=8.472,153.462,11.722,all P<0.05).Pearson correlation showed that at phylum level,AIM2 expression was positively correlated with the relative abundance of Firmicutes(r=0.598,P<0.05),and negatively correlated with the relative abundance of Bacteroides and Proteobacteria(r=-0.641,-0.520,all P<0.05).At the genus level,AIM2 expression was positively correlated with the relative abundance of Enterococcus and Escherichia coli(r=0.529,0.577,all P<0.05),and negatively correlated with the relative abundance of Bacteroides(r=-0.574,P<0.05).Among the 83 patients with advanced GC,17 cases were effective and 66 cases were ineffective,and the Overall response rate(ORR)was 20.48%.The lesion diameter(5.73±0.74cm)and the proportion of cTNM stage IV(53.85%)in AIM2 high expression group were significantly lower than those in low expression group(6.08±0.51cm,75.00%),and the targeted therapy ORR(30.77%)was higher than that in low expression group(11.36%),with statistical significance(t/χ2/Z=2.477,6.558,4.780,all P<0.05).Conclusion The expression of AIM2 in PBMC of advanced GC patients is closely related to the imbalance of intestinal flora and the effect of targeted therapy.Detection of AIM2 expression is conducive to guiding clinical screening of patients who benefit from targeted therapy.

Alzheimer's disease(AD)is a typical progressive neurodegenerative disease,mainly manifesting as severe cognitive dysfunction,and involving memory,thought processes,and emotion.The kynurenine pathway(KP)is one of the main metabolic pathways of tryptophan,which can be divided into neurotoxicity and neuroprotective branches.Increasing evidence has suggested that KP is involved in the pathogenesis of AD.This review considers the role of KP in the pathogenesis of AD,with reference to the relevant literature on KP interventions in AD in the PubMed database.The result will provide an important reference for the use of KP as a target for AD drug development.

Hepatic stellate cell(HSC)activation is a key link in the development of liver fibrosis.The metabolic reprogramming of activated HSC has become a hot topic in current research,especially the change of glycolysis is an important factor in regulating HSC activation.Based on the metabolic reprogramming in the process of HSC activation,this paper expounds the mechanism of regulating HSC activation and liver fibrosis through glycolysis,and reviews the research progress of traditional Chinese medicine and its active ingredients in regulating HSC glycolysis to prevent and treat liver fibrosis.Liver fibrosis is a complex pathological process involving multiple factors and pathways.From the perspective of regulating the glycolysis of activated HSC,it can provide a new idea for the development of anti-liver fibrosis drugs.

Objective:To investigate the risk factors for severe hyperbilirubinemia complicated by acute bilirubin encephalopathy (ABE), and the value of total serum bilirubin (TSB) and bilirubin (B)/albumin (A) ratio in predicting ABE.Methods:Clinical data of children with severe hyperbilirubinemia admitted to the Affiliated Hospital of Inner Mongolia Medical University, Ordos Central Hospital, People's Hospital of Inner Mongolia Autonomous Region, the Fourth Hospital of Baotou, Tongliao Hospital, Maternal and Child Health Hospital of Hohhot, the Affiliated Hospital of Chifeng University, Manzhouli People's Hospital, and Chifeng Hospital from January 1, 2020, to December 31, 2021, were retrospectively collected. The subjects were divided into ABE and non-ABE groups based on the occurrence of ABE. Multivariate logistic regression analysis was used to identify high-risk factors for ABE. Statistical analysis was performed using t-test, Wilcoxon signed-rank test, or Chi-square tests. Indicators with statistically significant differences were included in the multivariate logistic regression model, and stepwise regression was used to analyze the influencing factors of ABE. Results:(1) A total of 543 children were included in this study, accounting for 3.7% (543/14 831) of the total admissions during the same period. Among the 543 children, 81 (14.9%) had ABE, and 462 (85.1%) did not. The age at admission was (7.2±2.1) d, and the length of hospital stay was (5.2±2.2) d. The breastfeeding initiation time was 2 d (1-4 d) after birth. The peak TSB of the 543 cases was (385.98±51.22) μmol/L, and the age at peak TSB was (4.4±2.1) d. Fourteen cases (2.5%) gradually reached the peak TSB after admission [(392.01±61.24) μmol/L], while 529 cases (97.5%) had already reached the peak TSB at admission [(386.42±50.22) μmol/L]. Among the 543 cases, 356 had a clear etiology (65.6%, with 278 cases having a single cause and 78 cases having more than two causes), and 187 cases (34.4%) had an unknown etiology. (2) Compared with the non-ABE group, the breastfeeding initiation in the ABE group was later [6 h (2-6 h) vs. 2 h (1-3 h), Z=－6.87] and the length of hospital stay was longer [(6.5±1.9) d vs. (5.0±2.1) d, t=0.55]. The proportions of breastfeeding, delayed meconium passage, isoimmune hemolysis, and maternal gestational diabetes, as well as peak TSB and B/A ratio at peak TSB, were higher in the ABE group than in the non-ABE group [64.2% (52/81) vs. 36.8% (170/462), χ2=21.96; 16.0% (13/81) vs. 2.4% (11/462), χ2=27.32; 27.2% (22/81) vs. 10.6% (40/462), χ2=16.61; 24.7% (20/81) vs. 13.6% (63/462), χ2=6.50; (442±68) vs. (375±39) μmol/L, t=－8.55; (11.9±1.6) vs. (9.8±1.2), t=－11.61; all P<0.05]. The admission weight, proportion of transfer from the hospital's obstetrics department, unknown etiology, and breast milk jaundice were lower in the ABE group than in the non-ABE group [(3 098±482) vs. (3 278±493) g, t=3.04; 12.3% (10/81) vs. 42.4% (196/462), χ2=30.48; 3.7% (3/81) vs. 39.8% (184/462), χ2=39.83; 0.0% (0/81) vs. 5.8% (27/462), χ2=3.81; all P<0.05]. (3) Isoimmune hemolysis, peak TSB, and B/A ratio at peak TSB were independent risk factors for ABE [ OR(95% CI) were 2.924 (1.209-7.073), 1.006 (0.997-1.014), and 2.647 (1.841-3.805), respectively]. When the peak TSB was 380.05 μmol/L and the B/A ratio at peak TSB was 10.45, the sensitivity for predicting ABE was 0.963, the specificity was 0.789, and the area under the receiver operating characteristic curve was 0.752. Conclusions:Isoimmune hemolysis, peak TSB, and B/A ratio at peak TSB are independent risk factors for ABE. The B/A ratio at peak TSB and peak TSB can effectively predict ABE.

Objective:To investigate the application value of enhanced recovery after surgery (ERAS) in perioperative period of laparoscopic sleeve gastrectomy (LSG).Method:The retrospective cohort study was conducted. The clinical data of 1 181 patients undergoing LSG in the Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine from January 2021 to December 2023 were collected. There were 242 males and 939 females, aged (31±8)years. Of 1 181 patients, 598 cases receiving routine perioperative care were divided into the control group, and 583 cases receiving perioperative care with ERAS were divided into the ERAS group. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for comparison between the groups. Measurement data with skewed distribution were represented as M( Q1, Q3), and the Mann-Whitney rank sum test was used for comparison between the groups. Count data were expressed as absolute numbers or percentages, and the chi-square test or Fisher exact probability were used for comparison between the groups. Repeated measurement data were analyzed using the repeated ANOVA, with baseline scores as covariates. Simple effects analysis was conducted in case of interaction, and multiple comparisons were adjusted using the Bonferroni method. Results:(1) Postoperative outcomes. The numerical rating scale (NRS) scores for pain at immediate return to the ward and on the third postoperative mornings changed from 5.35±0.93 to 2.57±0.83 in the control group, versus changed from 3.15±0.93 to 0.70±0.65 in the ERAS group, showing significant difference between the two groups ( Ftime=66.58, Fgroup=1 765.85, Finteraction=6.90, P<0.05). After adjusting NRS scores for pain at immediate return to the ward as the baseline, results of simple effects analysis showed that on the third postoperative mornings, the NRS scores in the ERAS group were lower by 1.89, 1.53, and 1.76 respectively compared to the control group ( P<0.05). Cases with nausea at immediate return to the ward and on the third postoperative mornings changed from 497 to 97 in the control group, versus changed from 198 to 11 in the ERAS group, showing signifi-cant difference between the two groups ( χ2=294.45, 398.76,209.39, 73.00, P<0.05). Cases with vomiting at immediate return to the ward and on the third postoperative mornings changed from 243 to 41 in the control group, versus changed from 51 to 2 in the ERAS group, showing significant difference between the two groups ( χ2=160.54, 149.37, 71.76, 35.69, P<0.05). The duration of postoperative hospital stay was (3.22±0.65)days in the control group, versus (2.17±0.49)days in the ERAS group, showing a significant difference between the two groups ( t=-11.89, P<0.05). (2) Complications. The incidence of cases with dehydration within postoperative 30 days was 0.50%(3/598) in the control group, versus 0.69%(4/583) in the ERAS group, showing no significant difference between the two groups ( P>0.05). None of patient in the control group and the ERAS group experienced bleeding, gastric leakage, intra-abdominal infection, and no patient had unplanned secondary surgery within postoperative 30 days. Conclusions:ERAS in perioperative period of LSG are safe and feasible. Compared to routine care, ERAS can significantly reduce postoperative pain, decrease the incidence of postoperative nausea and vomiting, shorten the postoperative hospital stay, and do not increase the rate of postoperative complications or unplanned secondary surgeries within postoperative 30 days.

The STAR tool was used to evaluate and analyze the science, transparency, and applicability of Chinese pathology guidelines and consensus published in medical journals in 2022. There were a total of 18 pathology guidelines and consensuses published in 2022, including 1 guideline and 17 consensuses. The results showed that the guideline score was 21.83 points, lower than the overall guideline average (43.4 points). Consensus ratings scored an average of 27.87 points, on par with the overall consensus level (28.3 points). Areas that scored above the overall level were "conflict of interest" and "working groups", while areas that scored below the overall level were "proposals", "funding", "evidence", "consensus approaches" and "accessibility". To sum up, the formulation of pathology guidelines and consensuses in 2022 is not standardized, and the evidence retrieval process, evidence evaluation methods and grading criteria for recommendations on clinical issues are not provided in the formulation process; the process and method for reaching consensus are not provided, the plan is lacking, and registration is not carried out. It is therefore suggested that guidelines/consensus makers in the field of pathology should attach importance to evidence-based medical evidence, strictly follow guideline formulation methods and processes, further improve the scientific, applicable and transparent guidelines/consensuses in the field, and better provide support for clinicians and patients.
