Objective: To evaluate the feasibility and effectiveness of dual fluorescence laparoscopy in the localization of ureteral stricture and its blood supply，and to provide a new idea for the treatment of complex ureteral stenosis，thus helping doctors to improve the efficiency of ureteral reconstruction surgery. Methods: Our team developed a dual fluorescence laparoscopic system，which could simultaneously identify the ureter stricture by intra-ureteral injection of methylene blue (MB) and assess the blood supply of the ureteral stumps by intravenous injection of indocyanine green (ICG). Results: The clinical data of 3 patients who underwent lingual mucosa ureteroplasty using dual fluorescence laparoscopy in Zhongnan Hospital of Wuhan University were retrospectively analyzed.All operations were successful，without conversion to open surgery.The operation time was 144，132 and 163 minutes，respectively.The length of harvested lingual mucosa graft was 2.0，2.8 and 3.5 cm，respectively.No intraoperative or postoperative complications occurred.Eight weeks after operation，ureterography showed that the ureter was unobstructed. Conclusion: Dual fluorescence laparoscopy is safe and feasible in the repair of complex ureteral stricture with lingual mucosa graft，which provides a new idea for complex ureteral reconstruction.

Objective To analyze the relationship between serum microRNA(miR)-204 and miR-200b lev-els and clinical efficacy in patients with oral submucosal fibrosis(OSF).Methods A total of 110 patients with OSF who visited Affiliated Hospital of Hebei Engineering University from December 2021 to December 2022 were collected as the study group,another 50 healthy people who underwent physical examination during the same period were collected as the control group.The quantitative real-time PCR(qRT-PCR)method was ap-plied to detect and compare the serum levels of miR-204 and miR-200b in the study group and the control group.The study group was divided into miR-204 high expression group and low expression group,and miR-200b high expression group and low expression group.The clinical efficacy,transforming growth factor β1(TGF-β1),interleukin-6(IL-6),clinical pathological features,and visual analogue scale(VAS)of patients with different levels of serum miR-204 and miR-200b were compared,and Spearman and Pearson methods were applied to analyze the correlation between serum miR-204 and miR-200b levels and various indicators in the study group.Results The serum level of miR-204 and miR-200b in the study group was obviously lower than those in the control group,and the difference was statistically significant(P＜0.05).The total effective rates of patients in the high expression group of miR-204 and the high expression group of miR-200b were both 100.00％,which were higher than the total effective rates of the low expression group of miR-204 and the low expression group of miR-200b(86.79％and 88.89％)respectively,and the differences were statisti-cally significant(P＜0.05).The results of univariate analysis showed that the serum levels of miR-204 and miR-200b in OSF patients with chewing betel nut,mouth opening degree≤28 mm,oral mucosal lesion area＞4 cm2,and VAS score＞3 points were obviously lower than those with non chewing betel nut,mouth opening degree＞28 mm,oral mucosal lesion area≤4 cm2,and VAS score≤3 points,and the differences were statis-tically significant(P＜0.05).The levels of TGF-β1 and IL-6 in patients with high expression of miR-204 and miR-200b were obviously lower than those in patients with low expression of miR-204 and miR-200b,and the differences were statistically significant(P＜0.05).The correlation analysis results showed that the serum levels of miR-204 and miR-200b in patients with OSF were negatively correlated with oral mucosal lesion are-a,VAS score,TGF-β1,IL-6(P＜0.05),and positively correlated with mouth opening degree(P＜0.05).Conclusion The serum levels of miR-204 and miR-200b in patients with OSF are closely related to clinical ef-ficacy,and when the serum levels of miR-204 and miR-200b increase,OSF patients have better clinical efficacy.

Objective:To assess the safety and feasibility of selectively preserving the first branch of the right gastro-omental artery using bidirectional dissection in laparoscopic pylorus-preserving gastrectomy (LPPG).Methods:In this retrospective analysis, we studied preoperative, intraoperative, postoperative, and follow-up data of 30 patients with early gastric cancer treated in the Department of Gastric Cancer in Zhejiang Cancer Hospital (28 patients), Department of Gastrointestinal Surgery in Jiaxing Second Hospital (one patient) and Department of Gastrointestinal Surgery in Hangzhou Red Cross Hospital (one patient) who had undergone selective preservation of the first branch of the right gastro-omental artery during LPPG. The main variables studied were as follows: (1) intraoperative preservation of the first branch of the right gastro-omental artery; (2) the overall surgical situation; and (3) postoperative small bowel follow-through and endoscopy findings.Results:LPPG with selective preservation of the right gastro-omental artery vascular branch was achieved in all 30 of the study patients. The mean operation time was (244.3±29.3) minutes and the median intraoperative blood loss 50 (20–200) mL. The median tumor diameter was 1.2 (0.5–3.6) cm and an average of 32.3±11.6 lymph nodes were dissected. The overall median number of positive lymph nodes was 0 (0–6), and of No. 6 lymph nodes 5.1±1.5. Postoperative feeding resumed at an average of 5.2±0.5 days and the postoperative hospital stay averaged 8.4±3.4 days. Pathological stages were as follows: T1a (14 cases), T1b (10 cases), and T2 (6 cases). Small bowel follow-through imaging showed good results in 28 patients 5 days post-surgery, the remaining two exhibiting good results 9 days post-surgery. There were no instances of delayed gastric emptying, and only one patient (3.3%) developed intra-abdominal infection (resolved with conservative treatment).Conclusion:Selective preservation of the right gastro-omental artery during laparoscopic early gastric cancer surgery is a safe and feasible procedure for treating early mid-gastric body cancer with pyloric preservation.

Objective To investigate cyclin D2(CCND2)expression in papillary thyroid carcinoma(PTC)and its association with the clinicopathological features.Methods The public databases TCGA,TIMER 2.0 and UALCAN were used to explore CCND2 expression level in PTC and adjacent tissues,and its diagnostic value for PTC was analyzed using ROC curves.GO enrichment analysis of CCND2-related differentially expressed genes(DEGs)in PTC was performed,and tumor immune infiltration of CCND2 in thyroid cancer was analyzed using TIMER database and CIBERSORT data source.RT-qPCR and Western blot were used to detect CCND2 expression in normal human thyroid cell line Nthy-ori-3-1 and human PTC cell lines TPC-1 and BCPAP.CCND2 expression was also detected in clinical specimens of PTC and adjacent tissues by immunohistochemistry,and its correlation with clinicopathological features of the patients were analyzed.Results Informatic analysis revealed significantly higher CCND2 mRNA expression in thyroid cancer than in the adjacent tissues(P<0.001)in close correlation with tumor stage,gender,age,pathological subtype,and lymph node involvement(P<0.05).ROC curve analysis showed that at the cutoff value of 4.983,the diagnostic sensitivity,specificity,and accuracy of CCND2 expression for PTC was 83.6%,94.9%,and 78.5%,respectively.CCND2 expression was positively correlated with B cells,CD4+T cells,and macrophages(P<0.001)and negatively with CD8+T cells(P<0.01),and also correlated with memory B-cell infiltration,CD4+T-cell memory activation,M2 macrophages,resting mast cells,and mast cell activation(P<0.05).RT-qPCR,Western blot and immunohistochemistry showed significantly higher CCND2 expression in the PTC cells than in Nthy-ori-3-1 cells(P<0.01)and also in clinical PTC tissues than in the adjacent tissues(P<0.05)in correlation with tumor size,lymph node metastasis and TNM stage(P<0.05).Conclusion CCND2 overexpression is closely correlated with tumor progression and immune cell infiltration in PTC patients..

The density and composition of lymphocytes infiltrating colon tumors serve as predictive factors for the clinical outcome of colon cancer.Our previous studies highlighted the potent anti-cancer properties of the principal compounds found in Garcinia yunnanensis(YTE-17),attributing these effects to the regu-lation of multiple signaling pathways.However,knowledge regarding the mechanism and effect of YTE-17 in the prevention of colorectal cancer is limited.In this study,we conducted isobaric tags for relative and absolute quantification(iTRAQ)analysis on intestinal epithelial cells(IECs)exposed YTE-17,both in vitro and in vivo,revealing a significant inhibition of the Wnt family member 5a(Wnt5a)/c-Jun N-terminal kinase(JNK)signaling pathway.Subsequently,we elucidated the influence and mechanism of YTE-17 on the tumor microenvironment(TME),specifically focusing on macrophage-mediated T helper 17(Th17)cell induction in a colitis-associated cancer(CAC)model with Wnt5a deletion.Additionally,we performed the single-cell RNA sequencing(scRNA-seq)on the colonic tissue from the Wnt5a-deleted CAC model to characterize the composition,lineage,and functional status of immune mesenchymal cells during different stages of colorectal cancer(CRC)progression.Remarkably,our findings demon-strate a significant reduction in M2 macrophage polarization and Th17 cell phenotype upon treatment with YTE-17,leading to the restoration of regulatory T(Treg)/Th17 cell balance in azoxymethane(AOM)/dextran sodium sulfate(DSS)model.Furthermore,we also confirmed that YTE-17 effectively inhibited the glycolysis of Th17 cells in both direct and indirect co-culture systems with M2 macrophages.Notably,our study shed light on potential mechanisms linking the non-canonical Wnt5a/JNK signaling pathway and well-established canonical β-catenin oncogenic pathway in vivo.Specifically,we proposed that Wnt5a/JNK signaling activity in IECs promotes the development of cancer stem cells with β-catenin activity within the TME,involving macrophages and T cells.In summary,our study undergoes the po-tential of YTE-17 as a preventive strategy against CRC development by addressing the imbalance with the immune microenvironment,thereby mitigating the risk of malignancies.

Objective:To investigate alterations in brain functional connectivity (FC) in schizophrenia (SZ) model rats treated with Yudian decoction by using functional magnetic resonance imaging (fMRI).Methods:At 17th day of gestation in healthy SPF grade SD rats, a single intraperitoneal injection of methylazoxymethanol (MAM) (25 mg/kg) was used to induce abnormalities in monoamine neurotransmitters in pregnant female rats, thereby to establish a model of neural development abnormalities in the offspring. Four weeks old male offspring were selected as SZ model rats.Thirty SZ model rats were divided into model group, experimental group, and positive control group according to the body mass matching method, with 10 rats in each group. Additionally, 10 male offspring born to healthy female rats were selected as the blank control group.At 6 weeks of age, the rats in experimental group and positive control group were administered with Yudian decoction (1.54 g/kg) and risperidone (0.24 mg/kg) by gavage, respectively. The rats in blank control group and positive control group were administered with distilled water (6.7 mL/kg) by gavage.All the above interventions were conducted once a day for 14 consecutive days.The fMRI data were acquired from all samples using a 3.0 T MRI scanner. The bilateral hippocampus, bilateral prefrontal cortex, and bilateral striatum were designated as region of interest (ROI). FC comparisons between each pair of ROIs and whole-brain FC were conducted using two-sample t-test. Results:(1) Compared to the control group, the model group demonstrated enhanced whole-brain FC at the left cerebellar granular cell level (SIGMA: x=-2, y=-107, z=48) (cluster size=43, P<0.05, FWE adjusted under cluster-level). The experimental group exhibited increased whole-brain FC at the left cerebellar molecular layer (SIGMA: x=-5, y=-152, z=36) compared to the model group (cluster size=48, P<0.05, FWE adjusted under cluster-level). (2) Using the bilateral hippocampus as ROI, the positive control group exhibited enhanced FC at the deep layer of the superior colliculus (SIGMA: x=13, y=-77, z=27) compared to the model group (cluster size=88, P<0.05, FWE adjusted under cluster-level). The blank control group displayed decreased FC at the right granular insular cortex (SIGMA: x=43, y=19, z=9) compared to the model group (cluster size=125, P<0.05, FWE adjusted under cluster-level). Utilizing the bilateral prefrontal cortex as ROI, the experimental group showed reduced FC at the left cerebellar molecular layer (SIGMA: x=-14, y=-128, z=48) compared to the blank control group (cluster size=68, P<0.05 FWE adjusted under cluster-level). Conclusion:Schizophrenia is associated with abnormal whole-brain functional connectivity, notably characterized by enhanced functional connectivity in the hippocampal region.Yudian decoction demonstrates the capability to inhibit activity in the prefrontal cortex.

Methods Chinese medicine prescriptions for patients with thyroid nodules as clinical first diagnosis in the Department of Thyroid and Breast Surgery in Qingdao Hospital of Traditional Chinese Medicine from August 2018 to August 2023 were collected, and the Traditional Chinese Medicine Inheritance Assistant Platform (V3.0) was used to analyze the medication rules. Results A total of 1 206 traditional Chinese medicine prescriptions for the treatment of thyroid nodules were screened, involving 291 traditional Chinese medicines; the top five most frequently used drugs were Fritillaria thunbergii, Prunella vulgaris, Bupleurum chinense, Poria cocos, and Pinellia ternata; the main function of drugs were clearing heat, tonifying deficiency, resolving phlegm, activating blood circulation, and regulating qi; the main property of the drugs was cold, the main tastes of drugs were bitter, sweet and spicy, and the meridians involved were mainly the lung, liver and spleen meridians; association rule analysis identified 17 high-frequency drug combinations, with Fritillaria thunbergii-Prunella vulgaris as the most frequently occurring drug pair; among the 16 association rules, Radix Scrophulariae-Fritillaria thunbergii and Rhizoma Cyperi-Bupleurum chinense had the highest confidence level; clustering analysis found 6 core drug combinations. Conclusion The main idea of clinical treatment of thyroid nodules in traditional Chinese medicine is to resolve phlegm and reduce nodules, promote qi circulation and blood circulation, and nourish qi and blood; the common herbal combination of Fritillaria thunbergii and Prunella vulgaris is used to clear heat, resolve phlegm, and reduce nodules, and the basic formula for resolving scrofula is based on Xiaoluo Pills, which resolves phlegm, softens hardened nodules, and reduces nodules.

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.
