Objective:To evaluate the efficacy of multimodal prehabilitation in patients with refractory functional constipation undergoing Jinling procedure(modified Duhamel surgery).Methods:In this prospective randomized controlled trial,80 patients with refractory functional constipation scheduled for Jinling procedure at the Department of General Surgery,the General Hospital of Eastern Theater Command between January 2020 and December 2021 were enrolled.Participants were randomly assigned to either the observation group(n=40,multimodal prehabilitation)or control group(n=40,routine nursing care).Outcome measures included:time to first flatus,time to first ambulation,defecation volume on postoperative day 5,length of hospitalization,nutritional markers(hemoglobin,albumin,total protein at postoperative day 7),anxiety/depression scores(Hospital Anxiety and Depression Scale,HADS),and total complication rates.Results:Compared to controls,the first ventilation time(48.02±6.15)h,first ambulation time(49.92±5.58)h,defecation volume on the fifth day(234.50±51.03)mL,hospital stay(13.15±2.64)d,anxiety score(43.68±3.45)points,depression score(43.81±1.58)points,and the total incidence of postoperative complications(15%)were significantly lower in the observation group(all p values<0.05).By contrast,the serum levels of hemoglobin(115.60±11.60)g/l,albumin(41.19±5.79)g/L and total protein(61.64±4.94)g/L on day 7 post-operatively were significantly higher in the observation group than those in the control group(P<0.05).Conclusions:Multimodal prehabilitation enhances postoperative intestinal recovery,reduces complications,improves nutritional status,and shortens hospital stays in refractory functional constipation patients undergoing Jinling procedure,supporting its clinical adoption.

Forensic medicine has been designated as a first-level discipline,presenting new opportunities and challenges for the development of forensic medicine.Since the 1980s,the establishment of foren-sic medicine discipline and the cultivation of high-level forensic talents have become hot topics in the development of forensic medicine in China.Since the 13th Five-Year Plan,the forensic team of Shanxi Medical University has been aiming at the forefront,proposing the development goals of"Five First-class"and the discipline development path"Six Major Achievements".It has selected benchmark disci-plines,identified gaps in disciplinary development,unified thoughts,formulated completion timelines,concentrated superior resources,assigned tasks to individuals,and created an"Organized Fill-in-the-Blank Format"forensic medicine discipline construction model with the characteristics of the new era.The construction model of forensic medicine has achieved good results in the goals,discipline frame-work,scientific research,talent cultivation,discipline team and platform construction,forming a rela-tively complete discipline construction and management system,and accumulating valuable experience for the construction of first-level discipline and high-level talent cultivation of forensic medicine.

The prelimbic cortex (PL) plays a critical role in processing both the sensory and affective components of pain. However, the underlying molecular mechanisms remain poorly understood. In this study, we observed a reduction in hyperpolarization-activated cation current (I_h) in layer V pyramidal neurons of the contralateral PL in a mouse model of spared nerve injury (SNI). The expression of hyperpolarization-activated cyclic nucleotide-gated 2 (HCN2) channels was also decreased in the contralateral PL. Conversely, microinjection of fisetin, a partial agonist of HCN2, produced both analgesic and anxiolytic effects. Additionally, we found that cyclin-dependent kinase 5 (CDK5) was activated in the contralateral PL, where it formed a complex with HCN2 and phosphorylated its C-terminus. Knockdown of CDK5 restored HCN2 expression and alleviated both pain hypersensitivity and anxiety-like behaviors. Collectively, these results indicate that CDK5-mediated dysfunction of HCN2 in the PL underlies nerve injury-induced mechanical hypersensitivity and anxiety.

Recent studies have shown that an imbalance in iron metabolism can affect the composition and microstructural changes of bone, disrupting bone homeostasis and leading to osteoporosis(OP). The imbalance in iron metabolism, along with its induced local abnormal microenvironment and cellular iron death, has become a new focal point in OP research, drawing increasing attention from the academic community regarding the regulation of iron metabolism to prevent and manage OP. From the perspective of traditional Chinese medicine(TCM), iron metabolism imbalance has potential connections to TCM theories regarding internal organs, as well as treatments aimed at tonifying the kidney, strengthening the spleen, and activating blood circulation. Evidence is continually emerging that TCMs and effective components that tonify the kidney, strengthen the spleen, and activate blood circulation can prevent and manage OP by regulating iron metabolism. This article analyzes the relationship between iron and bone, as well as the effects of TCM formulations on improving iron metabolism and influencing bone metabolism, from the perspectives of iron metabolism mechanisms and TCM interventions, aiming to broaden existing clinical strategies for prevention and treatment and inject new momentum into the field of OP as it moves into a new era.

Objective:To investigate the clinical features and characteristics of gene mutation of patients with Hereditary spherocytosis(HS) and report novel mutations found in this work.Method:We reviewed the literatures for the clinical and genetic features of the 35 patients (24 boys and 11 girls, median age 7.8 years) with HS admitted to Wuhan Children′s Hospital from June 2017 to January 2023. Analyze clinical manifestations the blood routine, and biochemical laboratory results, and use Next-generation sequencing (NGS) to detect pathogenic mutation. Mann-Whitney U testing method was used to analyze the hematological parameters between different genotypes. Results:All of the patients showed clinical manifestations of anemia; 33 children had jaundice, 28 children had splenomegaly, and 11 children had gallstones. Gene mutations were detected in all 35 patients. 17 patients carried ANK1 variants, 14 patients harbored SPTB variants, 1 patient carried SPTA1variants, 1 patient carried SLC4A1 variants, and 2 patients harbored both ANK1 and SPTB variants. A total of 39 heterozygous mutations were found, among which 27 were pathogenic, 6 was likely pathogenic and 6 were of unknown significance according to the ACMG guideline; Among 39 mutations identified, 31 were novel. There were no significant differences in peripheral blood cell parameters and hemolysis indicators between the ANK1 mutant group and the SPTB group (all P>0.05). Conclusion:SPTB and ANK1 mutations are the most common mutations in HS pathogenic genes among patients in Hubei, China, and there was no significant difference in phenotype between ANK1 and SPTB genotype. We found 31 unreported novel variants and expanded the spectrum of variation in this type of disease .

Objective:To investigate the effects of Curcumol on the malignant biological characteristics of acute myeloid leukemia (AML)cells and its molecular mechanism,and to provide theoretical and experimental evidence for the anti-leukemia treatment of traditional Chinese medicine.Methods:After the AML cell lines HL-60 and KG-1 cells were treated different concentrations of with Curcumol.The proliferation activity of cells was detected by CCK-8 method,and the expression changes of apoptotic proteins and PI3 K/AKT signaling pathway proteins were detected by Western blot. Real-time quantitative fluorescence polymerase chain reaction (RT-qPCR ) was used to detect the expression of Caspase family mRNA.Results:Curcumol could inhibit the proliferation and induce apoptosis of HL-60 and KG-1 cells,promote apoptosis by up-regulating the expression of Bax and down-regulating the expression of Bcl-2 protein (P<0.05).When Curcumol interferes with HL-60 and KG-1 cells,it can also induce programmed cell death of AML by inhibiting PI3 K/AKT signaling pathway.In addition,after the intervention of Curcumol,the expression of Caspase 3,Caspase 6,Caspase 8 and Caspase 9 were up-regulated in HL-60 cells (P<0.05 ),the expression of Caspase 3,Caspase 8 and Caspase 9 were significantly up-regulated in KG-1 cells (P<0.01),while the expression of Caspase 6 was weakly affected (P<0.05 ),but low concentration of Curcumol (<60 μg/ml)had no effect on the expression of Caspase 6 in KG-1 cells (P>0.05).Conclusion:Curcumol may mediate the programmed death of AML cells by inhibiting the PI3K/AKT signaling pathway,affecting the expression of Bcl-2 family proteins,and promoting the activation of core members of Caspase family,so as to play an anti-leukemia role.

Aim To design the pyrimidoindole deriva-tive N-butyl-9H-pyrimido[4,5-b]indole-2-carboxamide(BFPI)and synthesize it to investigate whether it in-hibits macrophage pyroptosis and foaming effects through the NLRP3/Caspase-1 pathway.Methods BFPI was synthesized using 2,4,6-triethoxycarbonyl-l,3,5-triazine and 2-aminoindole as starting materials and structurally characterized by 1H NMR,13C NMR,and ESI-MS.The in vitro cultured mouse monocyte macro-phage cell line RAW264.7 was divided into blank,model(PA)and therapeutic(BFPI)groups,and the cells in each group were treated with the corresponding culture medium for 24 h.The proliferative viability was detected by MTT assay,and the formation of intracel-lular lipid droplets was detected by oil red O staining,and NLRP3 was detected by Western-blot and RT-qPCR,caspase-1 and MCP-1 mRNA and protein ex-pression levels by Western blot and RT-qPCR.Results Compared with the blank group,the proliferation vi-ability of cells in the model group significantly de-creased and the formation of lipid droplets significantly increased;compared with the model group,the prolif-eration viability of cells in the treatment group signifi-cantly increased and the formation of lipid droplets sig-nificantly decreased,and the differences were statisti-cally significant(P＜0.01);compared with the blank group,the cellular NLRP3,caspase-1 and MCP-1 mR-NA and protein expression levels of cells in the model group significantly increased;compared with the model group,the expression levels of the above indexes of the cells in the treatment group significantly decreased,and the difference was statistically significant(P＜0.01).Conclusions BFPI contributes to delaying macrophage-derived foam cell formation during athero-genesis by inhibiting macrophage NLRP3,caspase-1,and MCP-1 expression and thereby promoting their pro-liferation and inhibiting lipid phagocytosis.

Objective:To document any correlation between eye-tracking test results and cognitive impairment after a stroke.Methods:Forty stroke survivors made up the stroke group, while 20 healthy subjects without a history of stroke formed the normal group. Everyone was given an eye-tracking test, the mini-mental state examination (MMSE), and the Montreal Cognitive Assessment (MoCA). The eye-tracking test results were then tested for any correlation with age, level of education, and the MMSE and MoCA scores.Results:In the static image test and the prosaccade test, the total number of fixations was significantly higher in the stroke group than in the normal group. In the dynamic path test, the ocular motor test and the anti-saccade test, significant differences were observed between the two groups in terms of the duration of total fixation, the fixation duration ratio, and the total number of fixations. In the static image test, the total number of fixations was weakly negatively correlated with the MMSE scores. Total fixation duration and fixation duration ratio were weakly positively correlated with the MoCA scores, while total number of fixations, total saccade distance and average saccade velocity were weakly negatively correlated with the MoCA scores. In the dynamic path test, total fixation duration was weakly positively correlated with the MMSE and MoCA scores. Fixation duration ratio was weakly positively correlated with the MMSE scores and weakly negatively correlated with the MoCA scores. First fixation duration was weakly positively correlated with the MoCA scores. The total number of fixations was weakly positively correlated with age and weakly negatively correlated with the MoCA scores. Total saccade distance was weakly negatively correlated with age and the MoCA scores, and average saccade velocity was weakly negatively correlated with the MMSE and MoCA scores. In the ocular motor test, total fixation duration and fixation duration ratio were weakly positively correlated with the MoCA scores. Total number of fixations, total saccade distance, and average saccade velocity were weakly negatively correlated with the MoCA scores. In the prosaccade test, total fixation duration and fixation duration ratio were weakly positively correlated with the MoCA scores. Total number of fixations was weakly positively correlated with age and weakly negatively correlated with the MoCA scores. Total saccade distance and average saccade velocity were weakly negatively correlated with both the MMSE and MoCA scores. In the anti-saccade test, total fixation duration was weakly and positively correlated with age and the MoCA scores. Fixation duration ratio was weakly and positively correlated with age and the MoCA scores. The total number of fixations was weakly positively correlated with age and weakly negatively correlated with the MoCA scores, and total saccade distance and average saccade velocity were weakly negatively correlated with the MoCA scores.Conclusions:Eye-tracking test results are significantly correlated with post-stroke cognitive impairment, suggesting that such tests can be used in the assessment of post-stroke cognitive dysfunction.
