With the increasing use of lower-extremity arterial angioplasty and the clinical use of a variety of vascular preparation devices. Vascular surgeons have more vascular preparation equipment such as cutting balloon, double wire balloon, chocolate balloon, shock wave balloon, AngioJet, Roterax and Acostream. These options can improve clinical outcomes, improve patient experience, and reduce stent placement and associated complications. This article will review the available vascular preparation devices for volume reduction, endovascular lithotripsy, and other special balloons to help clinicians choose the appropriate vascular preparation for their condition to improve perioperative safety and long-term patency.

Objective To investigate the effect of right stellate ganglion block(SGB)on postoper-ative shoulder pain in patients receiving laparoscopic cholecystectomy(LC).Methods A total of 104 pa-tients scheduled for LC from April to August 2022,32 males and 72 females,aged 18-64 years,ASA phys-ical status Ⅰ orⅡ,were selected and randomized into two groups:the stellate ganglion block group(group S,n = 51)and the control group(group C,n = 53).Immediately after intubation,0.2%ropivacaine 4 ml was used for ultrasound-guided right SGB in group S,and saline 4 ml was injected at the same site in group C.The number of cases of post-laparoscopic shoulder pain(PLSP)and the duration of PLSP were re-corded within 48 hours after operation.The VAS pain scores of PLSP were recorded to assess the level of PLSP immediately after operation(T1),2 hours after operation(T2),6 hours after operation(T3),12 hours after operation(T4),24 hours after operation(T5),and 48 hours after operation(T6).The number of effective compressions of the PCIA pump and the salvage analgesia were recorded.The adverse reactions such as nausea,vomiting,and abdominal distension were recorded.Results The incidence of PLSP and the rate of patients with PLSP lasting more than 10 hours in group S was significantly lower than those in group C(P＜0.05),and the degree of PLSP in group S was significantly lower than that in group C at T3-T5(P＜0.05).The number of effective compressions of the PCIA pump and the salvage analgesia rate in group S was significantly lower than those in group C(P＜0.05).The incidence of nausea in group S was significantly lower than that in group C(P＜0.05).Conclusion Right stellate ganglion block can reduce the incidence of PLSP in patients receiving LC,relieve the pain degree of PLSP,and reduce the incidence of adverse reactions.

The application of function-preserving pancreatic surgery as a restrictive resection technique is primarily targeted towards benign or those with borderline or low-grade lesions. This approach has been shown to significantly improve both short-term and long-term quality of life outcomes for patients following surgical intervention. In comparison to conventional laparoscopic procedures, robotic surgical systems have demonstrated superior efficacy and precision when employed in pancreas surgeries, and the safety and reliability are widely recognized within the medical community. Nevertheless, there remains a dearth of research investigating the specific appli-cations of robotic-assisted function-preserving pancreatic surgery. Consequently, the authors compre-hensive review the latest progress on robot-assisted function-preserving pancreatic surgery, while highlighting of surgical scope, techniques utilized during these procedures as well as associated prognostic considerations.

Myeloid neoplasms (MNs) belong to a group of hematological malignancies characterized by the abnormal biological functions of hematopoietic stem progenitor cells. The abnormal immune and hematopoietic microenvironment of patients with MN interact with malignant clonal hematopoietic stem cells, promoting the occurrence and development of their diseases. MN large granular lymphocyte proliferation (MN-LGLP) is a special and rare clinical phenomenon in this type of disease. Currently, research on this disease in domestic and international cohorts is limited. This study analyzes the clinical and laboratory characteristics of this type of patient and explores the impact of LGLP on the clinical characteristics and survival of patients with MN. Patients with MN-LGLP are prone to neutropenia and splenomegaly. The presence of LGLP is not a risk factor affecting the survival of patients with MN-LGLP. STAG, ASXL1, and TET2 are the most common accompanying gene mutations in MN-LGLP, and patients with MN-LGLP and STAG2 mutations have poor prognoses.

Objective To investigate the expression of long non-coding RNA(lncRNA),surfactant associated 1 pseudogene(SFTA1P)in lung squamous carcinoma and its effect on the biological functions of SFTA1P in lung squamous carcinoma cell lines.Methods Based on the cancer genome atlas(TCGA)database,the differential expression of SFTA1P in tumor and normal tissues were compared in patients diagnosed with lung squamous cell carcinoma.Then,the expression of SFTA1P was detected in human normal lung epithelial cell line BEAS-2B and lung squamous cell lines SK-MES-1 and H520 with real-time quantitative polymerase chain reaction(RT-qPCR).SK-MES-1 and H520 cells with overexpression and/or knockdown of SFTA1P were constructed by transfecting the overexpression plasmids(pcDNA3.1-SFTA1P)and small interfering RNAs(si-SFTA1P-1 and si-SFTA1P-2).CCK-8 assay and Transwell assay were used to investigate the effect of SFTA1P on biological functions in lung squamous carcinoma cells.Differential gene expression analysis,correlation analysis and functional enrichment analysis were employed to explore the potential mechanism that SFTA1P may affect biological functions of lung squamous cells.Results Analysis of TCGA showed that the expression of SFTA1P was significantly lower in lung squamous cell carcinoma tissue than adjacent normal tissue(P＜0.05).RT-PCR results showed that the expression of SFTA1P was obviously lower in lung squamous carcinoma cells than the human normal lung epithelial cells(P＜0.05).And the expression level of SFTA1P was relatively lower in the SK-MES-1 cells than the H520 cells(P＜0.05).Overexpression of SFTA1P suppressed the proliferation,migration and invasion of lung squamous carcinoma cells(P＜0.05),while its knockdown promoted these abilities(P＜0.05).Differential gene expression analysis,correlation analysis and functional enrichment analysis indicated that SFTA1P may inhibit MYC,G2m checkpoints and E2f signaling pathways in lung squamous cell carcinoma.Conclusion SFTA1P shows anti-cancer function in lung squamous cell carcinoma,and it may affect the biological functions of lung squamous cell carcinoma cells through down-regulating MYC,G2m checkpoints and E2f signaling pathways.

Chronic venous insufficiency(CVI), a prevalent condition within vascular surgery, displays marked variation in prevalence in the world. The management of CVI poses a significant challenge to healthcare systems and profoundly impacts patients′ well-being, warranting heightened attention. Current therapeutic approaches to CVI encompass both non-surgical and surgical interventions. Non-surgical treatments aim to alleviate symptoms through compression and medication, while surgical methods focus on repairing or removing diseased veins to restore normal blood flow. However, the effectiveness of existing treatments remains suboptimal, necessitating further research and the exploration of novel therapeutic schedule. This review article delves into the attributes and characteristics of current treatment modalities for lower extremity venous insufficiency and speculates on potential future trends in management.

Objective To establish interferon-induced transmembrane protein 3(Ifitm3)knockout mice and to explore the effects of Ifitm3 on the proliferation and differentiation of adult neural stem cells of mice(aNSCs).Methods IFITM3 knockout mice were established by the CRISPR/Cas9 method and identified by genotype identification and Western Blot.The differences between Ifitm3-knockout mice and wild-type mice were analyzed by hematoxylin-eosin(HE)staining and flow cytometry.The aNSCs of wild-type mice and Ifitm3-knockout mice were isolated and cultured,the number and size of neurospheres were detected,The ability of aNSCs to proliferate and differentiate were detected by quantitative reverse-transcription polymerase chain reaction,Western Blot,and immunofluorescence.Results Ifitm3-knockout mice were successfully established.The mice developed normally,and there were no obvious abnormalities either histopathologically or the immune system.In vitro experiments showed that Ifitm3 knockout inhibited the self-renewal potential of aNSCs,led to a decrease in the proliferation ability of aNSCs,and inhibited the differentiation of aNSCs into immature neurons and astrocytes.Conclusions This study finds that a lack of IFITM3 result in the ability of aNSCs to proliferate and differentiate decreased,IFITM3 may regulate the function of aNSCs.

Objective:To investigate the eye movement characteristics of non-emotional pictures and emotion-al pictures in college students with different self-rating levels of depression.Methods:The Baker Depression Ques-tionnaire(BDI-2)was used to select 20 college students in high score group(BDI-2 score≥ 18 points)and 20 col-lege students in low score group(BDI-2 score ≤2 points).In experiment 1 the different finding tasks were used to investigate the difference of eye movement features between the two groups when viewing non-emotional pic-tures.In experiment 2 the expression recognition tasks were used to investigate the difference of the eye movement features between the two groups when viewing emotional pictures.Results:The results of experiment 1 showed that when completing the judgment task,the fixation times of each interest area of non-emotional images was smaller in the high score group than in the low score group(P＜0.01).The results of experiment 2 showed that the reaction time was longer to sad faces than to happy faces in the high score group(P＜0.05),and the correct rate to sad faces was higher in the high score group than in the low score group(P＜0.05).For the eye interest area,the first fixation arrival time was earlier in the high score group than in the low score group(P＜0.001),and the first fixa-tion time and total fixation time were shorter in the high score group than in the low score group(Ps＜0.01).Con-clusion:College students with high self-rating level of depression show a decrease of interest when viewing non-e-motional pictures,and show an advantage in processing negative emotional information and avoiding eye gaze when viewing emotional pictures.

Objective To provide the evidence for the development of personalized health education courses for twin pregnant women.We explored the health education and psychosocial demand of twin pregnant women from the perspective of social ecosystem theory.Methods By purposive sampling,18 twin pregnant women hospitalized in the twin medical center of a tertiary A hospital in Shenyang from January to March 2023 to conduct for semi-structured interviews,and Colaizzi's 7-step analysis method was used to sort out and analyze the data.Results 3 themes were extracted from the health education and psychosocial needs of twin pregnant women.Microsystem:the content needs of twin pregnant women's health education(the guidance needs of nutrition intake and weight growth;the needs for fetus health monitoring guidance;the cognitive needs of twin pregnancy complications;the needs for health education knowledge related to puerperium and the diversification of the choice of teaching methods).Mesosystem:the emotional support needs of twin pregnant women during prenatal and puetperal(the needs of family support and peer education support).Macrosystem:seeking social support and network information support(the demand of community support;the needs of information related to twin pregnant women's hierarchical management system and maternal fetal medical referral process and the needs for network health education information).Conclusion The women with twin pregnancy have different needs for health education content in each stage of pregnancy and puerperium,and there are urgent needs for emotional support and social support.Clinical nurses should construct health education courses according to the needs of twin women,and innovate in content and form,so as to improve the self-care ability of twin pregnant women and the knowledge level of family caregivers,and improve the pregnancy outcome.

‍ ObjectiveTo investigate the protective effect of safranal against sepsis-related liver injury （SRLI） induced by lipopolysaccharide （LPS） in mice and its mechanism. MethodsA total of 32 experimental male C57BL/6 mice were divided into control group， single drug group， model group， and treatment group using the simple random method， with 8 mice in each group. The mice in the single drug group and the treatment group were intraperitoneally injected with safranal （60 mg/kg） for 7 days of pretreatment， and the mice in the model group and the treatment group were intraperitoneally injected with LPS （10 mg/kg） to induce acute liver injury. The activities of serum alanine aminotransferase （ALT） and aspartate aminotransferase （AST） were measured； HE staining was used to observe liver tissue sections； immunohistochemistry was used to analyze the expression of the downstream protein heme oxygenase-1 （HO-1） in the signal pathway； TUNEL was used to analyze the apoptosis of hepatocytes； Western blot was used to measure the expression of total proteins （nuclear factor erythroid 2-related factor 2 ［Nrf-2］ and HO-1） in liver tissue. The human liver cell line L02 was pretreated with safranal （100 μmol/L）， followed by induction of acute hepatocellular injury with LPS （100 ng/mL）， and DCFH-DA fluorescent labeling was used to detect reactive oxygen species （ROS）. ResultsAfter safranal pretreatment， the treatment group had significantly lower levels of ALT and AST than the model group （both P<0.001）， with a relatively intact pseudolobular structure and a smaller necrotic area in the liver. Compared with the model group， the treatment group had significant increases in the expression levels of Nrf2 and HO-1 in liver tissue after safranal+LPS treatment （both P<0.001）， and immunohistochemistry showed that safranal pretreatment increased the number of HO-1-positive cells. In the cell model of LPS-induced acute liver injury， the treatment group had a significant reduction in the production of ROS compared with the model group. ConclusionSafranal can exert a protective effect against SRLI induced by LPS in mice through the Nrf2/HO-1 pathway.
