Objective To investigate the correlation between WT1,BCR-ABL genes and interleukin-6(IL-6),vascular endothelial growth factor(VEGF),plasma protein C(PC),plasma protein S(PS)in patients with myeloproliferative neoplasms(MPN).Methods A total of 54 MPN patients treated in this hospital from January 2021 to January 2024 were selected as the MPN group,and 54 healthy subjects undergoing physical examination during the same period were selected as the control group.The gene relative expression levels of WT1,BCR-ABL and levels of IL-6,VEGF,PC,and PS were detected and compared between the two groups.The correlations between WT1,BCR-ABL gene relative expression levels and IL-6,VEGF,PC,PS levels were analyzed,and the diagnostic efficacy of WT1 and BCR-ABL genes for MPN was evaluated by receiver operat-ing characteristic(ROC)curve.Results Compared with the control group,the gene relative expression levels of WT1,BCR-ABL and the levels of IL-6 and VEGF in the MPN group were higher,while the levels of PC and PS were lower,with statistically significant differences(P<0.05).Pearson correlation analysis showed that WT1 and BCR-ABL gene relative expression levels were positively correlated with IL-6 and VEGF levels,and negatively correlated with PC and PS levels(P<0.05).The combined use of WT1 and BCR-ABL genes has higher diagnostic efficacy for MPN than single indicators,with an area under the curve(AUC)of 0.833 and a sensitivity of 88.69%.Conclusion The relative expression levels of WT1 and BCR-ABL genes are correlated with IL-6,VEGF,PC,and PS levels in MPN patients.The combination of WT1 and BCR-ABL genes can effec-tively diagnose MPN.

OBJECTIVE Aimed to investigate the impact of comorbid asthma on chronic rhinosinusitis with nasal polyps(CRSwNP)and identify key proteins and signaling pathways.METHODS Proteomic methods were employed to analyze differentially expressed proteins(DEPs)in nasal lavage fluid(NLF)from control,CRSwNP,and CRSwNP with asthma groups.DIA quantitative analysis technology was used to assess the gradient changes of DEPs among the three groups to determine key proteins affected by comorbid asthma in CRSwNP.RESULTS Compared to the control group,1 377 and 1 006 DEPs were identified in the CRSwNP and CRSwNP with asthma groups,respectively.Peroxiredoxin-5(PRDX5),Ran-Binding Protein 1(RanBP1)(upregulated),and Keratin 9(KRT9)(downregulated)were identified as key proteins affecting CRSwNP with asthma.CONCLUSION Comorbid asthma may promote the occurrence and development of nasal polyps through specific key proteins and signaling pathways,providing new molecular insights into the interaction between CRSwNP and asthma.

Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Objective To explore the mechanism of immediate effect regulated by acupuncture on acupoints in patients with migraine without aura(MwoA)during the interictal period.Methods A total of 28 MwoA patients were enrolled and resting-state functional magnetic resonance imaging(rs-fMRI)were performed at baseline and after acupuncture for 30 minutes.Paired t test was used to compare the differences of regional homogeneity(ReHo)and voxel-mirrored homotopic connectivity(VMHC)between two groups.Additionally,the correlation between the changes of rs-fMRI indexes and clinical scores was analyzed.Results In MwoA patients after acupuncture for 30 minutes,the mean regional homogeneity(mReHo)was decreased in the right lingual gyrus and right cere-bellum and was increased in the right middle frontal gyrus,while the z transformation voxel-mirrored homotopic connectivity(zVMHC)was significantly decreased in the bilateral cuneus compared with baseline.There was no significant correlation between imaging data and clinical scales.Conclusion Patients with MwoA after acupuncture for 30 minutes show abnormal ReHo and VMHC in multiple brain regions,which suggest that the mechanism of immediate effect may act through regulating pain-related brain regions.

OBJECTIVE To explore the independent factors affecting tissue inflammatory cells changes in recurrent nasal polyps.METHODS The clinical data of 31 patients with nasal polyps who underwent endoscopic surgery at the Department of Otolaryngology Head and Neck Surgery,Yantai Yuhuanding Hospital from December 2007 to December 2021 were selected and analyzed by stepwise regression logistic analysis.RESULTS The number of tissue inflammatory cells in recurrent nasal polyps changed compared with that in primary nasal polyps,and the number and percentage of neutrophils in recurrent polyps increased(P<0.05).Logistic analysis revealed that smoking was an independent risk factor for eosinophilia in recurrent nasal polyps,increasing age was an independent factor for lowering neutrophils,and the comorbid allergic rhinitis and the time interval of recurrence were independent factors for lowering and increasing lymphocytes,respectively.CONCLUSION The number of tissue-infiltrating cells is altered in recurrent polyps compared with primary polyps.Smoking is an independent risk factor for eosinophilia in recurrent polyps.

Objective To analyze the relationship between the expression of hsa_circ_401724 and the in-flammatory response in type 2 diabetes mellitus(T2DM)patients and pancreatic islet cell function.Methods A total of 102 patients with T2DM treated in Linfen Central Hospital from April 2017 to December 2022 were selected as the observation group,and 100 healthy subjects with normal glucose tolerance were se-lected as the control group during the same period.The levels of tumor necrosis factor α(TNF-α),interleukin-6(IL-6)and intercellular adhesion molecule-1(ICAM-1)in the blood of the subjects were detected by en-zyme-linked immunosorbent assay to evaluate the levels of inflammatory factors in the subjects.The relative expression level of hsa_circ_401724/U6 was calculated according to the dissolution curve,and the pancreatic islet cell function of the subjects was assessed,including homeostasis model assessment of insulin resistance(HOMA-IR)and homeostatic model assessment beta cell function(HOMA-β)as assessed by homeostasis model.Pearson correlation was used to analyze the correlation between hsa_circ_401724 expression level and inflammation and pancreatic islet cell function,and Logistics regression model was used to analyze the rela-tionship between hsa_circ_401724 expression level and inflammation and pancreatic islet cell function.Results The levels of HOMA-IR,TNF-α,IL-6 and ICAM-1 in observation group were significantly higher than those in control group,while the levels of HOMA-β in observation group were significantly lower than those in control group,with statistical significance(P＜0.05).The relative expression level of hsa_circ_401724 in observation group(0.75±0.13)was significantly higher than that in control group(0.24±0.06),and the difference was statistically significant(P＜0.05).The levels of HOMA-IR,TNF-α,IL-6 and ICAM-1 in hsa_circ_401724 high expression group were significantly higher than those in hsa_circ_401724 low expres-sion group,and the levels of HOMA-β were significantly lower than those in hsa_circ_401724 low expression group.The difference was statistically significant(P＜0.05).The relative expression level of hsa_circ_401724 was positively correlated with the levels of HOMA-IR,TNF-α,IL-6 and ICAM-1(r=0.657,0.671,0.703,0.698,P＜0.05).hsa_circ_401724 expression level was negatively correlated with HOMA-β level(r=-0.611,P＜0.05).The high expression of hsa_circ_401724 was an independent risk factor affecting the levels of HOMA-IR,HOMA-β,TNF-α,IL-6 and ICAM-1 in T2DM patients(P＜0.05).Conclusion The high ex-pression of hsa_circ_401724 is related to the inflammatory response and the decline of pancreatic islet cell function in T2DM patients.

Objectives:This study aims to explore the clinical significance of lateral pelvic sentinel lymph node biopsy (SLNB) using indocyanine green (ICG) fluorescence navigation in laparoscopic lateral pelvic lymph node dissection (LLND) and evaluate the accuracy and feasibility of this technique to predict the status of lateral pelvic lymph nodes (LPLNs).Methods:The clinical and pathological characteristics, surgical outcomes, lymph node findings and perioperative complications of 16 rectal cancer patients who underwent SLNB using ICG fluorescence navigation in laparoscopic LLND in the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during April 2017 and October 2022 were retrospectively collected and analyzed. The patients did not receive preoperative neoadjuvant radiotherapy and presented with LPLNs but without LPLN enlargement (MRI showed the maximum short axes of the LPLNs were ≥5 mm and <10 mm at first visit).Results:All 16 patients were successfully performed SLNB using ICG fluorescence navigation in laparoscopic LLND. Three patients underwent bilateral LLND and 13 patients underwent unilateral LLND. The lateral pelvic sentinel lymph nodes (SLNs) were clearly fluorescent before dissection in 14 patients and the detection rate of SLNs for these patients was 87.5%. Lateral pelvic SLN metastasis was diagnosed in 2 patients and negative results were found in 12 patients by frozen pathological examinations. Among the 14 patients in whom lateral pelvic SLNs were detected, the dissected lateral pelvic non-SLNs were all negative. All dissected LPLNs were negative in two patients without fluorescent lateral pelvic SLNs. The specificity, sensitivity, negative predictive value, and accuracy was 85.7%, 100%, 100%, and 100%, respectively.Conclusions:This study indicates that lateral pelvic SLNB using ICG fluorescence navigation shows promise as a safe and feasible procedure with good accuracy. This technique may replace preventive LLND for locally advanced lower rectal cancer.

Objective:To investigate the expression level of long non-coding RNA (lncRNA) CTC-338M12.4 in tongue squamous cell carcinoma tissues, and its effects on the cell cycle, cell proliferation, and migration of tongue squamous cell carcinoma cells in vitro as well as its molecular mechanisms.Methods:The Gene Expression Omnibus (GEO) database was used to obtain the lncRNA series data set GSE139869, and the differential expression of CTC-338M12.4 in tongue squamous cell carcinoma tissues and adjacent tissues was analyzed. The transcriptional expression levels of CTC-338M12.4 in human immortalized oral keratinocytes (HOK) and tongue squamous cell carcinoma cell lines HN13, TSCCa, CAL-27, Tca8113, SCC15 were detected by using reverse transcription quantitative real-time polymerase chain reaction (qRT-PCR). CAL-27 cells with the lowest expression level of CTC-338M12.4 were selected and were divided into the control group (co-transfected with vectors containing negative sequence) and CTC-338M12.4 group (co-transfected with CTC-338M12.4 overexpression vectors). The proliferation ability of CAL-27 cells in each group was detected by using cell colony formation assay, and the cell cycle distribution of CAL-27 cells was detected by using flow cytometry. The migration ability of CAL-27 cells was detected by using scratch test. The lncACTdb database was used to predict the complementary binding sites between CTC-338M12.4 and miRNA-27a-5p (miR-27a-5p), and dual-luciferase reporter gene assay was used to verify. The expression level of miR-27a-5p in CAL-27 cells of all groups was detected by using qRT-PCR. The protein expression level of related factors on JAK/STAT signaling pathway in CAL-27 cells of all groups was detected by using Western blot.Results:Analysis of GEO database data showed that transcriptional level CTC-338M12.4 in tongue squamous cell carcinoma tissues was lower than that in adjacent tissues, and the difference was statistically significant ( P < 0.01). Transcriptional level CTC-338M12.4 in tongue squamous cell carcinoma HNl3, TSCCa, CAL-27, Tca8113, and SCC15 cells was lower than that in HOK cells, and the differences were statistically significant (all P < 0.05). The transcriptional level relative expression level of CTC-338M12.4 in CAL-27 cells in the CTC-338M12.4 group was higher than that in the control group, and the difference was statistically significant ( P < 0.01). Cell colony formation assay showed that the colong number of CAL-27 cell in the CTC-338M12.4 group was less than that in the control group [(51±10) vs. (114±21)], and the difference was statistically significant ( t = 2.71, P = 0.035). Flow cytometry showed that the proportion of G 0/G 1 phase cells in CAL-27 cells in the CTC-338M12.4 group was higher than that in the control group [(64±3)% vs. (43±4)%], and the difference was statistically significant ( t = 4.87, P = 0.003). The scratch test showed that when scratching, the scratch width of both groups was similar ( P > 0.05); after scratch for 25 h, the scratch width of CAL-27 cells in the CTC-338M12.4 group was wider than that in the control group [(133±15) μm vs. (64±10) μm], and the difference was statistically significant ( t = 3.78, P = 0.009). The dual luciferase reporter gene assay showed that the relative luciferase activity of CAL-27 cells co-transfected with wild-type CTC-338M12.4 sequence and miR-27a-5p sequence was lower than that of CAL-27 cells co-transfected with wild-type CTC-338M12.4 sequence and miR-27a-5p irrelevant sequence, and the difference was statistically significant ( P < 0.001). The relative expression level of transcriptional level miR-27a-5p of CAL-27 cells in the CTC-338M12.4 group was lower than that in the control group, and the difference was statistically significant ( P = 0.003). Western blot showed that the protein expression levels of JAK/STAT signaling pathway p-JAK, p-STAT, p-Raf, p-ERK, and p-mTOR were lower than those in the control group. Conclusions:The level of lncRNA CTC-338M12.4 is low in tongue squamous cell carcinoma. CTC-338M12.4 mediates the inactivation of JAK/STAT signaling pathway via inhibiting miR-27a-5p expression in tongue squamous cell carcinoma CAL-27 cells, thereby leading to cell cycle arrest and inhibiting the cell proliferation and migration of CAL-27 cells.
